The ESI also recovers costs associated with CL&P’s system resiliency program, which was implemented as part of CL&P's rate case settlement agreement that was approved by PURA in April 2018.program. The ESI is adjusted periodically and reconciled annually in accordance with the policies and procedures of the PURA, with any differences refunded to, or recovered from, customers.

An FMCC,A Federally Mandated Congestion Charge (FMCC), which recovers any costs imposed by the FERC as part of the New England Standard Market Design, including locational marginal pricing, locational installed capacity payments, any costs approved by the PURA to reduce these charges, as well as other costs approved by PURA.  The FMCC has both a bypassable component and a non-bypassable component, and is adjusted periodically and reconciled annually in accordance with the policies and procedures of the PURA, with any differences refunded to, or recovered from, customers.

Distribution Rate Case: CL&P's distribution rates were established in an April 2018 PURA-approved rate case settlement agreement with rates effective May 1, 2018, and incremental step adjustments effective May 1, 2019 and May 1, 2020.

SourcesCL&P Settlement Agreement: In accordance with a 2021 settlement agreement, CL&P agreed that its current base distribution rates would be frozen, subject to certain customer credits, until no earlier than January 1, 2024. The rate freeze applied only to base distribution rates (including storm costs) and Availability of Electric Power Supply

As noted above, CL&P does not ownto other rate mechanisms such as the retail rate components, rate reconciling mechanisms, formula rates and any generation assets and purchases energy supplyother adjustment mechanisms. The rate freeze also did not apply to serve its SS and LRS loads from a variety of competitive sources through requests for proposals. During 2020, CL&P supplied approximately 51 percent of its customer load at SS or LRS rates while the other 49 percent of its customer load had migrated to competitive energy suppliers.  In termsany cost recovery mechanism outside of the total number of CL&P customers, this equatesbase distribution rates with regard to 23 percent being on competitive supply, while 77 percent remain with SSgrid-modernization initiatives or LRS. Because this customer migration is only for energy supply service, it has no impactany other proceedings that were either pending or that could be initiated during the rate freeze period, that could have placed additional obligations on CL&P's electric distribution business or its operating income.

CL&P periodically enters into full requirements contracts for SS loads for periods of up to one year. CL&P typically enters into full requirements contracts for LRS loads every three months. Currently, CL&P has full requirements contracts in place for 100 percent of its SS loads for the first half of 2021. For the second half of 2021, CL&P has 40 percent of its SS load under full requirements contracts and intends to purchase an additional 60 percent of full requirements. None&P. The approval of the SS load for 2022 has been procured. CL&P has fullsettlement agreement satisfied the Connecticut statute of rate review requirements contracts in place for its LRS loads through March 2021 and intendsthat requires electric utilities to purchase 100 percent of full requirements for the remainder of 2021.

NSTAR Electric does not own any generating facilities that are used to supply customers, and purchases its energy requirements from competitive energy suppliers.

NSTAR Electric owns, operates and maintains a total of 70 MW of solar power facilities on twenty-two sites in Massachusetts.  NSTAR Electric will sell energy from these facilities into the ISO-NE market, with proceeds credited to customers.

Rates

NSTAR Electric is subject to regulation by the DPU, which, among other things, has jurisdiction over rates, certain dispositions of property and plant, mergers and consolidations, issuances of long-term securities, acquisition of securities, standards of service and construction and operation of facilities.  The present general rate structure for NSTAR Electric consists of various rate and service classifications covering residential, commercial and industrial services.

Under Massachusetts law, all customers of NSTAR Electric are entitled to choose their energy suppliers, while NSTAR Electric remains their electric distribution company.  NSTAR Electric purchases power from competitive suppliers on behalf of, and passes the related cost through to, its customers who do not choose a competitive energy supplier (basic service). Electric distribution companies in Massachusetts are required to obtain and resell power to retail customers through basic service for those who choose not to buy energy from a competitive energy supplier.  Most of the residential customers of NSTAR Electric have continued to buy their power from NSTAR Electric at basic service rates.  Most commercial and industrial customers have switched to a competitive energy supplier.

The Cape Light Compact, an inter-governmental organization consisting of the 21 towns and two counties on Cape Cod and Martha's Vineyard, serves 200,000 customers through the delivery of energy efficiency programs, consumer advocacy, competitive electricity supply and green power options.  NSTAR Electric continues to provide electric service to these customers including the delivery of power, maintenance of infrastructure, capital investment, meter reading, billing, and customer service.

The rates established by the DPU for NSTAR Electric are comprised of the following:

A basic service charge that represents the collection of energy costs incurred as a result of providing electric generation service supply to all customers that have not migrated to competitive energy suppliers, including costs related to charge-offs of uncollectible energy costs from customers.  Basic service rates are reset every six months (every three months for large commercial and industrial customers). Additionally, the DPU has authorized NSTAR Electric to recover the cost of its NSTAR Green wind contracts through the basic service charge. Basic service costs are reconciled annually, with any differences refunded to, or recovered from, customers.Operations.

CL&P Performance Based Rate MakingA: PURA currently has an open proceeding to evaluate and eventually implement performance based regulation (PBR) for electric distribution charge, which includes a fixed customer chargecompanies.

The transmission charge is reconciled annually to actual costs incurred and reviewed by the DPU, with any difference refunded to, or recovered from, customers.

A transition charge that represents costs to be collected primarily from previously held investments in generating plants, costs related to existing above-market power contracts, and contract costs related to long-term power contract buy-outs. The transition charge is reconciled annually to actual costs incurred and reviewed by the DPU, with any difference refunded to, or recovered from, customers.

A renewable energy charge that represents a legislatively-mandated charge to support the Massachusetts Renewable Energy Trust Fund.

An energy efficiency charge that represents a legislatively-mandated charge to collect costs for energy efficiency programs. The energy efficiency charge is reconciled annually to actual costs incurred and reviewed by the DPU, with any difference refunded to, or recovered from, customers.

Reconciling adjustment charges that recover certain DPU-approved costs, including pension and PBOP benefits, low income customer discounts, credits issued to net-metering facilities installed by customers, payments to solar facilities qualified under the state solar renewable energy target program, attorney general consultant expenses, long-term renewable contracts, company-owned solar facilities, vegetation management costs, credits related to the Tax Cuts and Jobs Act of 2017, grid modernization costs, and storm restoration. These charges are reconciled annually to actual costs incurred and reviewed by the DPU, with any difference refunded to, or recovered from, customers.

NSTAR Electric has signed long-term commitments for the purchase of energy from renewable energy facilities.

Distribution Rate Case: NSTAR Electric's distribution rates were established in a 2017 DPU-approved rate case with rates effective February 1, 2018. DPU-approved inflation-based adjustments to annual base distribution amounts were effective January 1, 2019, 2020 and 2021.

Service Quality Metrics: NSTAR Electric is subject to service quality (SQ) metrics that measure safety, reliability and customer service, and could be required to pay to customers a SQ charge of up to 2.5 percent of annual transmission and distribution revenues for failing to meet such metrics. NSTAR Electric will not be required to pay a SQ charge for its 2020 performance as the company achieved results at or above target for all of its SQ metrics in 2020.

Sources and Availability of Electric Power Supply

As noted above, CL&P does not own any generation assets and purchases energy supply to serve its SS and LRS loads from a variety of competitive sources through requests for proposals. During 2023, CL&P supplied approximately 56 percent of its customer load at SS or LRS rates while the other 44 percent of its customer load had migrated to competitive energy suppliers.  In terms of the total number of CL&P customers, this equates to 25 percent being on competitive supply, while 75 percent remain with SS or LRS. Because customer migration is limited to energy supply service, it has no impact on CL&P's electric distribution business or its operating income.

As approved by PURA, CL&P periodically enters into full requirements supply contracts for SS loads for periods of up to one year. CL&P typically enters into full requirements supply contracts for LRS loads every three months. If CL&P does not obtain full requirements supply contracts for 100 percent of the customer load for any period, it is authorized by PURA to meet the remaining load obligations directly through the ISO-NE wholesale markets. Currently, CL&P has full requirements supply contracts in place for 100 percent of its SS load for the first half of 2024. For the second half of 2024, CL&P has 70 percent of its SS load under full requirements supply contracts and intends to purchase an additional 30 percent of full requirements. Ten percent of the SS load for 2025 has been procured. CL&P obtained a full requirements supply contract for its LRS load through June 2024 and intends to purchase 100 percent of full requirements for LRS for the remainder of 2024. CL&P is prepared to self-manage the LRS load if unable to obtain full requirements supply contracts for LRS.

As approved by the NHPUC, PSNH has signed long-term commitments for the purchase of energy from renewable energy facilities.

Distribution Rate Case: On June 27, 2019, the NHPUC approvedPSNH’s distribution rates were established in a December 2020 NHPUC-approved settlement agreement, that was reached by PSNH, the NHPUC Staff, the Office of the Consumer Advocate, and another settling party, to implement a temporary annual base distribution rate increase of $28.3 million. Although newwith rates were implemented on August 1, 2019 to customers, the provisions of the temporary base distribution rate increase were effective July 1, 2019. The settlement agreement also permitted PSNH to recover approximately $68.5 million in unrecovered storm costs over a five-year period beginning August 1, 2019, with debt carrying charges, which is included in the temporary rate increase.

On May 28, 2019, PSNH filed an application with the NHPUC for a permanent increase in base distribution rates of approximately $70 million, effective July 1, 2020, which included the temporary rate increase request. Temporary rates remained in effect with a reconciliation of permanent rates retroactive to July 1, 2019 once permanent rates were set.

On December 15, 2020, the NHPUC approved an October 9, 2020 settlement agreement on permanent rates between PSNH and all parties to the proceeding. The NHPUC approved a permanent rate increase of $45.0 million effective January 1, 2021, inclusive of the temporary rate increase referenced above.2021. PSNH was also permitted three step increases, effective January 1, 2021, August 1, 2021, and August 1, 2022, to reflect plant additions in calendar years 2019, 2020 and 2021, respectively. The NHPUC approved a rate increase effective February 1, 2022 designed to collect $1.1 million dollars annually to fund a reserve account to pay for arrearage forgiveness for customers with past due balances and the New Start Program. On December 23, 2020,October 20, 2022, the NHPUC approved the firstthird step adjustment for 20192021 plant in service to recover a revenue requirement of $10.6$8.9 million, subject to reconciliation after completion of an audit,with rates effective JanuaryNovember 1, 2021.2022. The settlement agreement also established an authorized regulatory ROE of 9.3 percent with a 54.4 percent common equity ratio in PSNH’s capital structure and provided for a new tracker to recover regulatory assessments, vegetation management costs, property tax costs, and lost distributiontotal approved revenue attributable to net metering.

Generation Divestiture

On January 10, 2018, PSNH completedrequirement increase was collected over the sale of its thermal generation assets. The original purchase price of $175 million was adjusted to reflect working capital adjustments, closing date adjustments and proration of taxes and fees prior to closing. As a result of these adjustments, net proceeds from the saleremainder of the thermal assets totaled $116.8 million. On August 26, 2018, PSNH completed the sale of its hydroelectric generation assets. The original purchase price of $83 million was adjusted to reflect contractual adjustments, resulting in net proceeds of $77.2 million. The difference between the carrying value of the hydroelectric generation assets and the sale proceeds resulted in a gain of $17.3 million. An estimated gain from the sale of these assets was included as an offset to the total remaining costs associated with the sale of generation assets that were securitized on May 8, 2018.

rate year (November 1, 2022 – July 31, 2023).
On May 8, 2018, PSNH Funding issued $635.7 million of securitized RRBs pursuant to a finance order issued by the NHPUC on January 30, 2018 to recover remaining costs resulting from the divestiture of PSNH’s generation assets, which included the deferred costs resulting from the sale of the thermal generation assets. These RRBs are secured by a non-bypassable charge recoverable from PSNH customers. PSNH recorded regulatory assets and other deferred costs in connection with the generation asset divestiture and the securitization of remaining costs, which are probable of recovery through collection of the non-bypassable charge.

On May 15, 2020, the NHPUC Audit Staff issued a final report on the audit of PSNH’s generation asset divestiture-related costs and resulting securitized and stranded costs. The findings in the audit report as well as other aspects of the divestiture process were further investigated by NHPUC Staff through the discovery phase, which was completed in July 2020. On September 30, 2020, PSNH filed a settlement agreement on the generation asset divestiture-related costs with the NHPUC Audit Staff. The settlement agreement resolved all issues with respect to PSNH’s divestiture of its generating assets and the recovery of $12.0 million of divestiture-related costs incurred above the $635.7 million amount previously securitized. On December 17, 2020, the NHPUC approved the additional $12.0 million proposed in the settlement agreement to be recovered over a one-year period through the SCRC rate beginning February 1, 2021.

Sources and Availability of Electric Power Supply

PSNH does not own any generation assets and as approved by the NHPUC, purchases energy supply from a variety of competitive suppliers for its energy service customers through requests for proposals issued twice per year, for six-month terms, for approximately 8064 percent of its residential and small C&I customers and for 159 percent of its large C&I customers.

During 2020,2023, PSNH supplied approximately 4637 percent of its customer load at default energy service rates while the other 5463 percent of its customer load had migrated to competitive energy suppliers. Because this customer migration is only forlimited to energy supply service, it has no impact on PSNH’s electric distribution business or its operating income.

ELECTRIC TRANSMISSION SEGMENT

Each of CL&P, NSTAR Electric and PSNH ownseach own and maintainsmaintain transmission facilities that are part of an interstate power transmission grid over which electricity is transmitted throughout New England.  Each of CL&P, NSTAR Electric and PSNH, and most other New England utilities, are parties to a series of agreements that provide for coordinated planning and operation of the region's transmission facilities and the rules by which they acquire transmission services.  Under these arrangements, ISO-NE, a non-profit corporation whose board of directors and staff are independent of all market participants, serves as the regional transmission organization of the New England transmission system.  

Wholesale Transmission Rates

Wholesale transmission revenues are recovered through FERC-approved formula rates.  Annual transmission revenue requirements include recovery of transmission costs and include a return on equity applied to transmission rate base. Transmission revenues are collected from New England customers, including distribution customers of CL&P, NSTAR Electric and PSNH.  The transmission rates provide for an annual true-up of estimated to actual costs.  The financial impacts of differences between actual and estimated costs are deferred for future recovery from, or refund to, transmission customers.

Transmission Rate Base

Transmission rate base under our FERC-approved tariff primarily consists of our investment in transmission net utility plant less accumulated deferred income taxes. Under our FERC-approved tariff, investments in net utility plant generally enter rate base after they are placed in commercial operation. At the end of 2023, our estimated transmission rate base was approximately $9.8 billion, including approximately $4.1 billion at CL&P, $3.9 billion at NSTAR Electric, and $1.8 billion at PSNH.

FERC ROE Complaints

Four separate complaints were filed at the FERC by combinations of New England state attorneys general, state regulatory commissions, consumer advocates, consumer groups, municipal parties and other parties (collectively, the "Complainants")Complainants). In each of the first three complaints, filed on October 1, 2011, December 27, 2012, and July 31, 2014, respectively, the Complainants challenged the NETOs' base ROE of 11.14 percent that had been utilized since 2005 and sought an order to reduce it prospectively from the date of the final FERC order and for the separate 15-month complaint periods. In the fourth complaint, filed April 29, 2016, the Complainants challenged the NETOs' base ROE billed of 10.57 percent and the maximum ROE for transmission incentive (incentive cap) of 11.74 percent, asserting that these ROEs were unjust and unreasonable.

In response to appeals of the FERC decision in the first complaint filed by the NETOs and the Complainants, the U.S. Court of Appeals for the D.C. Circuit (the Court) issued a decision on April 14, 2017 vacating and remanding the FERC's decision. On October 16, 2018, FERC issued an order on all four complaints describing how it intends to address the issues that were remanded by the Court. FERC proposed a new framework to determine (1) whether an existing ROE is unjust and unreasonable and, if so, (2) how to calculate a replacement ROE.

On November 21,During 2019 and 2020, FERC also issued Opinion No. 569 affecting themultiple decisions in two pending transmission ROE complaints against the Midcontinent ISO (MISO) transmission owners, in which FERC adopted a new methodologymethodologies for determining base ROEs. Various parties sought rehearing. On December 23, 2019,August 9, 2022, the NETOs filed supplementary materials inCourt issued a decision vacating these MISO FERC decisions and remanded to FERC to reopen the NETOs' four pending cases to respond toproceedings. At this new methodology because oftime, Eversource cannot predict how and when FERC will address the uncertainty of the applicability to the NETOs' cases. On May 21, 2020, the FERC issued its order in Opinion No. 569-ACourt’s findings on the rehearingremand of the MISO transmission owners' cases, in which FERC again changed its methodology for determiningopinions or any potential associated impact on the MISO transmission owners' base ROEs. Various parties appealed the MISO transmission owners' opinion. On November 19, 2020, the FERC issued Opinion No. 569-B denying rehearing of Opinion No. 569-A and reaffirmed the methodology previously adopted in Opinion No. 569-A. The new methodology differs significantly from the methodology proposed by FERC in its October 16, 2018 order to determine the NETOs' base ROEs in itsNETOs’ four pending ROE complaint cases.

Given the significant uncertainty regarding the applicability of the FERC opinions in the MISO transmission owners' two complaint cases to the NETOs' pending four complaint cases, Eversource concluded that there is no reasonable basis for a change to the reserve or recognized ROEs for any of the complaint periods at this time. As well, Eversource cannot reasonably estimate a range of any gain or loss for any of the four complaint proceedings at this time.

Transmission Projects

During 2020, we were involved in the planning, development and construction of a series of electric transmission projects that enhance system reliability and improve capacity. For more information on transmission projects, see "Business Development and Capital Expenditures – Electric Transmission Business" in the accompanying Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations.

Northern Pass was Eversource's planned 1,090 MW HVDC transmission line that would have interconnected from the Québec-New Hampshire border to Franklin, New Hampshire and an associated alternating current radial transmission line between Franklin and Deerfield, New Hampshire. As a result of a final decision received on July 19, 2019 from the New Hampshire Supreme Court, whereby the court denied Northern Pass’ appeal and affirmed the NHSEC’s denial of Northern Pass’ siting application on NPT, Eversource concluded that construction of NPT was no longer probable and that there was no constructive path forward for the project. In 2019, Eversource terminated the project and permanently abandoned any further development.  As a result, substantially all of the capitalized project costs, which totaled $318 million, certain of which were subject to cost reimbursement agreements, were impaired. In total, this resulted in a pre-tax impairment charge of $239.6 million within Operating Income on the statement of income for the year ended December 31, 2019, and was reflected in the Electric Transmission segment. For further information, see "Critical Accounting Policies - Impairment of Northern Pass Transmission" in the accompanying Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations.

Transmission Rate Base

Transmission rate base under our FERC-approved tariff primarily consists of our investment in transmission net utility plant less accumulated deferred income taxes. Under our FERC-approved tariff, and with the exception of transmission projects that received specific FERC approval to include CWIP in rate base, transmission projects generally enter rate base after they are placed in commercial operation. At the end of 2020, our estimated transmission rate base was approximately $8.0 billion, including approximately $3.6 billion at CL&P, $3.1 billion at NSTAR Electric, and $1.3 billion at PSNH.

NATURAL GAS DISTRIBUTION SEGMENT

On October 9, 2020, Eversource acquired certain assets and liabilities that comprised NiSource’s natural gas distribution business in Massachusetts, which was previously doing business as CMA, pursuant to an asset purchase agreement (the Agreement) entered into on February 26, 2020 between Eversource and NiSource Inc. (NiSource). The cash purchase price was $1.1 billion, plus a target working capital amount of $69.6 million, which is subject to adjustment to reflect actual working capital as of the closing date that has not yet been finalized. Eversource financed the asset acquisition through a combination of debt and equity issuances in a ratio that was consistent with our consolidated capital structure. The natural gas distribution assets acquired from CMA were assigned to Eversource Gas Company of Massachusetts (EGMA), an indirect wholly-owned subsidiary of Eversource formed in 2020. The LNG assets acquired from CMA were assigned to Hopkinton LNG Corp.

EGMA distributes natural gas to approximately 332,000336,000 customers in 6566 communities throughout Massachusetts covering 1,206 square miles.Massachusetts. Yankee Gas distributes natural gas to approximately 246,000252,000 customers in 7485 cities and towns in Connecticut covering 2,632 square miles.Connecticut. Total throughput (sales and transportation) in 20202023 was approximately 66.967.1 Bcf for NSTAR Gas, 54.954.2 Bcf for EGMA, and 54.656.4 Bcf for Yankee Gas. Our natural gas businesses provide firm natural gas sales and transportation service to eligible retail customers who require a continuous natural gas supply throughout the year, such as residential customers who rely on natural gas for heating, hot water and cooking needs, as well as commercial and industrial customers thatwho rely on natural gas for space heating, hot water, cooking and commercial and industrial applications.

A portion of the storage of natural gas supply for NSTAR Gas and EGMA during the winter heating season is provided by Hopkinton LNG Corp., an indirect, wholly-owned subsidiary of Eversource Energy. NSTAR Gas has access to facilities consisting of a LNG liquefaction and vaporization plant and three above-ground cryogenic storage tanks having an aggregate capacity of 3.0 Bcf of liquefied natural gas and facilities that include additional storage capacity of 0.5 Bcf. Total vaporization capacity of these facilities is 0.21 Bcf per day. EGMA has access to approximately 1.8 Bcf of LNG and 0.2 Bcf of Liquefied Petroleum Gas (LPG) storage, with a total vaporization capacity of 0.17 Bcf per day. Yankee Gas owns a 1.2 Bcf LNG facility, which also has the ability to liquefy and vaporize up to 0.1 Bcf per day. This facility is used primarily to assist Yankee Gas in meeting its supplier-of-last-resort obligations and also enables it to provide economic supply and make economic refill of natural gas, typically during periods of low demand.

NSTAR Gas, EGMA and Yankee Gas generate revenues primarily through the sale and/or transportation of natural gas.  All NSTAR Gas and EGMA retail customers have the ability to choose to purchase gas from third party marketers under the Massachusetts Retail Choice program. In the past year in Massachusetts, Retail Choice represented only approximately one percent of the total residential load, while Retail Choice represented approximately 5950 percent of the total commercial and industrial load. Retail natural gas service in Connecticut is partially unbundled: residential customers in Yankee Gas' service territory buy natural gas supply and delivery only from Yankee Gas while commercial and industrial customers may choose their natural gas suppliers. For customers who purchase natural gas from NSTAR Gas, EGMA and Yankee Gas, the purchased natural gas commodity cost is passed through to those customers without mark-up. NSTAR Gas, EGMA and Yankee Gas do not earn a profit on the cost of purchased gas.

Firm transportation service is offered to customers who purchase natural gas from sources other than NSTAR Gas, EGMA or Yankee Gas. NSTAR Gas and EGMA have the ability to offer interruptible transportation and interruptible natural gas sales service to high volume commercial and industrial customers. Yankee Gas offers interruptible transportation and interruptible natural gas sales service to commercial and industrial customers thatwho have the ability to switch from natural gas to an alternate fuel on short notice. NSTAR Gas, EGMA and Yankee Gas can interrupt service to these customers during peak demand periods or at any other time to maintain distribution system integrity.

Rates

NSTAR Gas and EGMA are subject to regulation by the DPU and Yankee Gas is subject to regulation by the PURA, both of which, among other things, have jurisdiction over rates, certain dispositions of property and plant, mergers and consolidations, issuances of long-term securities, standards of service and construction and operation of facilities.

Retail natural gas delivery and supply rates are established by the DPU and the PURA and are comprised of:

A distribution charge consisting of a fixed customer charge and a demand and/or energy charge that collects the costs of building, maintaining, and expanding the natural gas infrastructure to deliver natural gas supply to its customers.  This also includes collection of ongoing operating costs.

A seasonal cost of gas adjustment clause (CGAC) at NSTAR Gas and EGMA that collects natural gas supply costs, pipeline and storage capacity costs, costs related to charge-offs of uncollected energy costs and working capital related costs.  The CGAC is reset semi-annually with any difference being recovered from, or refunded to, customers during the following corresponding season. In addition, NSTAR Gas and EGMA file interim changes to the CGAC factor when the actual costs of natural gas supply vary from projections by more than five percent.

A Purchased Gas Adjustment (PGA) clause which is evaluated monthly and allowsat Yankee Gas to recoverthat collects the costs of the procurement of natural gas for its firm and seasonal customers. The PGA is evaluated monthly.  Differences between actual natural gas costs and collection amounts from September 1st through August 31st of each PGA year are deferred and then recovered from, or refunded to, customers during the following PGA year.  Carrying charges on outstanding balances are calculated using Yankee Gas' weighted average cost of capital in accordance with the directives of the PURA.

A local distribution adjustment clause (LDAC) at NSTAR Gas and EGMA that collects all energy efficiency and related program costs, environmental costs, pension and PBOP related costs, attorney general consultant costs, credits related to the Tax Cuts and Jobs Act of 2017, gas system enhancement program (GSEP) costs, and costs associated with low income customers.customers, and costs associated with a geothermal pilot program.  The LDAC is reset annually with any difference being recovered from, or refunded to, customers during the following period and provides for the recovery of certain costs applicable to both sales and transportation customers.

8


A Conservation Adjustment Mechanism (CAM) at Yankee Gas, which allows 100 percent recovery of conservation costs through this mechanism including program incentives to promote energy efficiency.  A reconciliation of CAM revenues to expenses is performed annually with any difference being recovered from, or refunded to, customers with carrying charges during the following year.

A Gas System Improvement (GSI) reconciliation mechanism at Yankee Gas, which collects the costs of certain Distribution Integrity Management Program (DIMP) and core capital plant in service above and beyond the level that is recovered through the distribution charge. The GSI is adjusted and reconciled annually, with any differences refunded to, or recovered from, customers.

A System Expansion Rate (SER) Reconciliation Mechanismreconciliation mechanism at Yankee Gas, which compares distribution system expansion investment costs and revenues for newfrom system expansion customers with the level projected in current distribution customer rates.  This reconciliation is performed annually and customer rates are adjusted accordingly.

A Revenue Decoupling Mechanism (RDM) at NSTAR Gas and EGMA that reconciles annual base distribution rate recovery amounts recovered from customers to the pre-established level of baseline distribution delivery service revenue requirement approved by the DPU in 2020.DPU. The pre-established level of baseline distribution delivery service revenue requirement is also subject to adjustment in accordance with provisions of the November 2020 NSTAR Gas distribution rate case and the October 2020 EGMA rate settlement agreement.

A RDM at Yankee Gas that reconciles annual base distribution rate recovery amounts recovered from customers to the pre-established level of baseline distribution delivery service revenue requirement approved by the PURA effective January 1, 2019, January 1, 2020 and March 1, 2021.PURA. The pre-established level of baseline distribution delivery service revenue requirement is also subject to adjustment at each of these dates in accordance with provisions of the 2018 rate case settlement agreement.

NSTAR Gas purchases financial contracts based on the New York Mercantile Exchange (NYMEX) natural gas futures in order to reduce cash flow variability associated with the price for approximately one-third of its normal winter season natural gas supplies.  These purchases are made under a program approved by the DPU in 2006.  This practice attempts to minimize the impact of fluctuations in natural gas prices to NSTAR Gas' firm natural gas customers.  These financial contracts do not procure natural gas supply.  All costs incurred or benefits realized when these contracts are settled are included in the CGAC.

NSTAR Gas is subject to SQ metrics that measure safety, reliability and customer service and could be required to pay to customers a SQ charge of up to 2.5 percent of annual distribution revenues for failing to meet such metrics.  NSTAR Gas will not be required to pay a SQ charge for its 2020 performance as it achieved results at or above target for all of its SQ metrics in 2020.

NSTAR Gas' 2019 plant additions are allowed recovery beginning on November 1, 2021.  Thus, the reduced revenue requirement reflects the removal of this recovery, among other adjustments.2020. The DPU also approved NSTAR Gas' proposal to continue its ongoing Gas System Enhancement Program (GSEP), the inclusion of GSEP investments since 2015 into base rates, and the implementation of a 10-year performance-based ratemakingPBR plan through November 1, 2030, which includes an inflation-based adjustment mechanismadjustments to annual base distribution rates. The decision allows an authorized regulatory ROEamounts effective annually beginning November 1, 2021. For further information, see "Regulatory Developments and Rate Matters - Massachusetts" in the accompanying Item 7, Management's Discussion and Analysis of 9.9 percent on a capital structure including 54.77 percent equity. The decision also approves a geothermal pilot program.

Yankee Gas: Yankee Gas distribution rates were set in a December 2018 PURA approved rate case settlement agreement, with rates effective November 15, 2018. The 2018 Yankee Gas settlement agreement required Yankee Gas to implement a GSI cost recovery mechanism to further invest capital to replace aging infrastructure. The GSI mechanism allows for recoveryFinancial Condition and Results of costs associated with capital additions of approximately $26 million to $37 million annually, which is incremental to the $150 million included in base distribution rate base per year. The settlement agreement also provides Yankee Gas the opportunity to seek recovery of additional capital spending above these levels with PURA approval. PURA ordered an accelerated replacement program for Yankee Gas to fully replace its cast iron and bare steel facilities in 11 years and fully replace copper services and certain steel mains and services in 14 years from the date of the rate case. Yankee Gas was also authorized to continue its ongoing natural gas system expansion program, implement a revenue decoupling rate mechanism, and recover merger costs. The settlement agreement included a regulatory ROE of 9.3 percent. In addition, the distribution rates charged to customers were adjusted to reflect the prospective impacts of the lower federal corporate income tax rate, the overcollection of the lower income tax rate from January 1, 2018, and the EDIT from the Tax Cuts and Jobs Act of 2017. Although new rates were effective January 1, 2019, the provisions of the settlement agreement took effect November 15, 2018. PURA also approved step adjustments effective January 1, 2019, January 1, 2020 and March 1, 2021.Operations.

EGMA: OnEGMA’s distribution rates were established in a DPU-approved October 7, 2020 the DPU approved a rate settlement agreement, with Eversource, EGMA, NiSource, Bay State, the Massachusetts Attorney General's Office, the DOER and the Low-Income Weatherization and Fuel Assistance Program Network, which requested approval of the February 26, 2020 asset purchase agreement between Eversource and NiSource, as well as a rate stabilization plan, among other items. The settlement agreement included an authorized regulatory ROE of 9.70 percent as of January 1, 2021, a 53.25 percent equity component of its capital structure, and established rate base equal to $995 million as of the closing on October 9, 2020.

The approved rate stabilization plan includes base distribution rate increases of $13 million on November 1, 2021 and $10 million on November 1, 2022. The settlement agreement includes2022, and two rate base resets during an eight-year rate plan, occurring on November 1, 2024 and November 1, 2027. The two rate base resets adjust distribution rates to account for capital additions (including the roll-in of GSEP capital additions), depreciation expense, property taxes, and return on rate base for capital additions placed into service through December 31, 2023, for the first rate base reset occurring on November 1, 2024, and through December 31, 2026, for the second rate base reset occurring on November 1, 2027. Notwithstanding the two distribution rate increases, the two rate base reset provisions, and potential adjustments for qualifying exogenous events, EGMA agreed not to file for an increase or redesign of distribution base rates effective prior to November 1, 2028.

TheYankee Gas: Yankee Gas distribution rates were established in a December 2018 PURA-approved rate case settlement agreement, with rates effective November 15, 2018. PURA also permitsapproved step adjustments effective January 1, 2020 and January 1, 2021.

Natural Gas Replacement and Expansion

Massachusetts: Pursuant to Massachusetts legislation, in October of each year, NSTAR Gas and EGMA file GSEP Plans with the DPU for the following construction year. The GSEP Program is designed to accelerate the replacement of certain natural gas distribution facilities in the system to less than 25 years.  The GSEP includes a tariff that provides NSTAR Gas and EGMA an opportunity to collect the costs for the program on an annual basis through a reconciling factor.  On April 30th each year, the DPU approves the GSEP rate recovery factor that goes into effect on May 1st.

NSTAR Gas' distribution rate case application filed on November 8, 2019 included a proposal to include GSEP additions through 2018 into base distribution rates and to continue the operation of the GSEP mechanism for GSEP investments made after 2018. In addition, the filing included a proposal for a customer connection surcharge, which would be used to reduce up-front contribution in aid of construction (CIAC) costs for customers seeking to connect to the company’s distribution system. On October 30, 2020, the DPU approvedopened Docket “DPU 20-80 The Future of Gas” to examine the Company’srole of Massachusetts natural gas local distribution companies (LDCs) in helping to meet the state’s 2050 climate goals. In December 2023, the DPU issued an order for this docket. The DPU will consider and, in some cases, require new processes and analysis for traditional natural gas investments, which may require significant changes to the LDC planning process and business models. The DPU intends to put policies and structures in place that would protect customers as Massachusetts works to decarbonize the building sector, which may involve subsequent dockets and regulatory proceedings and potentially recasting the role of LDCs in Massachusetts. The DPU preserved customer connection surcharge proposal, allowingchoice for energy needs and encouraged further development of decarbonized alternatives, such as the surchargenetworked geothermal systems that NSTAR Gas is piloting in Framingham, Massachusetts. At this time, Eversource cannot predict the ultimate outcome of this proceeding, as the Company and other LDCs are seeking formal clarity from the DPU to be implemented beginning November 1, 2021.fully understand the resulting impact to their natural gas businesses and the associated timing of any impacts. The Company does not believe there is any indication of an inability to recover costs or risk of impairment of our natural gas assets at this time.

Connecticut: Yankee Gas' December 2018 PURA approvedPURA-approved rate case settlement agreement included an accelerated pipeline replacement cost recovery program. The Gas System Improvement (GSI)GSI rate recovers accelerated pipeline replacement as well as other capital investment through an annual reconciliation. The Company filedYankee Gas files its first GSI reconciliation annually on March 1, 20191st for rates effective April 1, 2019 and will continue to file annually on March 1 for rates effective April 1.1st.

In 2013, in accordance with Connecticut law and regulations, the PURA approved a comprehensive joint natural gas infrastructure expansion plan (the "Expansion Plan") filed by Yankee Gas and other Connecticut natural gas distribution companies.  In January 2015, the PURA approved a joint settlement agreement proposed by Yankee Gas and other Connecticut natural gas distribution companies and regulatory agencies that clarified the procedures and oversight criteria applicable to the Expansion Plan.  Yankee Gas received approval from PURA for its 2014 through 2019 System Expansion Reconciliations. The Company intends to file its 2020 System Expansion Reconciliation in March 2021 as required by PURA.

In September 2021, PURA undertook a review of Connecticut natural gas companies’ infrastructure system expansion plan (SEP) to determine if the SEP continues to be in the best interest of the state’s comprehensive energy strategy. On April 27, 2022, PURA issued an order for the immediate winding down of the SEP by (1) ending the enrollment of new customers in the SEP program and permitting only a specific group of potential customers who have executed a services agreement with a natural gas company on or before a specified date (subsequently approved as August 16, 2022) to qualify for incentives under the current SEP; (2) directing all surplus non-firm margin to be deferred as a regulatory liability and applied to rate base in a future rate proceeding; and (3) directing the natural gas companies to cease all outbound and passive marketing regarding the SEP. On July 15, 2022, Yankee Gas appealed the portion of this order pertaining to the deferral of non-firm margin as a reduction to future rate base. On October 24, 2023, Yankee Gas informed the Connecticut Superior Court that the parties mutually agreed to resolve the appeal through a stipulation, which clarified that PURA will decide in Yankee Gas’s next gas rate case the ratemaking treatment of the deferred non-firm margin. Yankee Gas evaluated the prospective impact of this proceeding and does not believe the impact will be material to its future financial position, results of operations and cash flows.

Sources and Availability of Natural Gas Supply

NSTAR Gas maintains aand EGMA maintain flexible resource portfolioportfolios consisting of natural gas supply contracts, transportation contracts on interstate pipelines, market area storage and peaking services. NSTAR Gas purchasesand EGMA purchase transportation, storage, and balancing services from Tennessee Gas Pipeline Company and Algonquin Gas Transmission Company, as well as other upstream pipelines that transport natural gas from major natural gas producing regions in the U.S., including the Gulf Coast, Mid-continent region, and Appalachian Shale supplies(as well as Ontario, Canada specific to EGMA), which supply to the final delivery points in the NSTAR Gas and EGMA service area.areas. NSTAR Gas purchases all of its natural gas supply under a firm, competitively bid annual portfolio management contract. In addition to the firm transportation and natural gas storage supplies discussed above, NSTAR Gas utilizes on-system LNG facilities to meet its winter peaking demands. These LNG facilities are located within NSTAR Gas' distribution system and are used to liquefy and store pipeline natural gas during the warmer months for vaporization and use during the heating season. During the summer injection season, excess pipeline capacity and supplies are used to deliver and store natural gas in market area underground storage facilities located in Maryland and Pennsylvania. Stored natural gas is withdrawn during the winter season to supplement flowing pipeline supplies in order to meet firm heating demand. NSTAR Gas has firm underground storage contracts and total storage capacity entitlements of approximately 6.6 Bcf, of which 3.5 Bcf LNG storage is provided by Hopkinton LNG Corp. in facilities located in two different locations in Massachusetts.

EGMA maintains a flexible resource portfolio consisting of natural gas supply contracts, transportation contracts on interstate pipelines, market area storage and peaking services. EGMA purchases transportation, storage, and balancing services from Tennessee Gas Pipeline Company and Algonquin Gas Transmission Company, as well as other upstream pipelines that transport natural gas from major natural gas producing regions in the U.S. as well as Canada, including the Gulf Coast, Mid-continent region, Appalachian Shale, and Dawn, Ontario supplies to the final delivery points in the EGMA service area. EGMA purchases the majority of its natural gas supply under a number of firm, competitively bid annual portfolio management contracts, and manages a portion of its portfolio itself.own portfolio. In addition to the firm transportation and natural gas storage supplies discussed above, NSTAR Gas and EGMA utilizesutilize on-system LNG andfacilities (and also LPG facilities for EGMA) to meet its winter peaking demands. These LNG and LPG facilities are located within NSTAR Gas' and EGMA’s distribution systemsystems and are used to liquefy pipeline natural gas and/or receive liquefied natural gas or liquefied petroleum gas to be stored during the warmer months for vaporization and use during the heating season. During the summer injection season, excess pipeline capacity and supplies are used to deliver and store natural gas in market area underground storage facilities located in Maryland and Pennsylvania. Stored natural gas is withdrawn during the winter season to supplement flowing pipeline supplies in order to meet firm heating demand. EGMANSTAR Gas has firm underground storage contracts and total storage capacity entitlements of approximately 6.6 Bcf, and 2.03.5 Bcf LNG storage is provided by Hopkinton LNG Corp. in facilities located in two different locations in Massachusetts. EGMA has firm underground storage contracts and total storage capacity entitlements of approximately 8.6 Bcf, and 1.9 Bcf LNG and LPG storage is provided by Hopkinton LNG Corp. in facilities located at eightseven different locations in Massachusetts.

The PURA requires Yankee Gas to meet the needs of its firm customers under all weather conditions. Specifically, Yankee Gas must structure its supply portfolio to meet firm customer needs under a design day scenario (defined as the coldest day in 30 years) and under a design year scenario (defined as the average of the four coldest years in the last 30 years). Yankee Gas also maintains a flexible resource portfolio consisting of natural gas supply contracts, transportation contracts on interstate pipelines, off-system storage and its on-system 1.2 Bcf LNG storage facility in Connecticut to meet consumption needs during the coldest days of winter. Yankee Gas obtains its interstate capacity from the three interstate pipelines that directly serve Connecticut: the Algonquin, Tennessee and Iroquois Pipelines, which connect to other upstream pipelines that transport natural gas from major natural gas producing regions, including the Gulf Coast, Mid-continent, Canadian regions and Appalachian Shale supplies.

Based on information currently available regarding projected growth in demand and estimates of availability of future supplies of pipeline natural gas, each of NSTAR Gas, EGMA and Yankee Gas believes that in order to meet the long-term firm customer requirements in a reliable manner, will necessitate a combination of pipeline, storage, and non-pipeline solutions.solutions will be necessary.

The rates established by the PURA, DPU and NHPUC are comprised of the following:

A base rate, which is comprised of fixed charges based on meter/fire connection sizes, as well as volumetric charges based on the amount of water sold. Together these charges are designed to recover the full cost of service resulting from a general rate proceeding.

In Connecticut, a revenue adjustment mechanism (RAM) that reconciles earned revenues, with certain allowed adjustments, on an annual basis, to the revenue requirement approved by the PURA in AWC-CT’s last rate case (2013), which is an annual amount of $178.0 million.PURA.

In Connecticut and New Hampshire, a water infrastructure conservation adjustment (WICA) charge, and in Massachusetts, an annual main replacement adjustment mechanism (MRAM) charge, which is applied between rate case proceedings and seeks recovery of allowed costs associated with eligible infrastructure improvement projects placed in-service. The WICA is updated semi-annually in Connecticut and annually in New Hampshire. In Connecticut, an annual WICA reconciliation mechanism reconciles earned WICA revenue to the approved WICA revenue with any differences refunded to, or recovered from, customers.

In Massachusetts, treatment plant surcharges, which are a series of three surcharges (one fixed and two volumetric in nature) that are designed to recover certain operating costs and the costs of the lease of the treatment plant located in Hingham.  These surcharges were applicable only to customers in Hingham, Hull and Cohasset. On July 31, 2020, we sold our water system and treatment plant that supplies water to the towns of Hingham, Hull and North Cohasset to the town of Hingham, Massachusetts. For further information, see "Regulatory Developments and Rate Matters - Massachusetts - Sale of Water System" in the accompanying Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations.

Sources and Availability of Water Supply

Our water utilities obtain their water supplies from owned surface water sources (reservoirs) and groundwater supplies (wells) with a total supply yield of approximately 118135 million gallons per day, as well as water purchased from other water suppliers. Approximately 9998 percent of our annual production is self-supplied and processed at nineten surface water treatment plants and numerous well stations, which are all located in Connecticut, Massachusetts, and New Hampshire.

The capacities of Aquarion’s sources of supply, and water treatment, pumping and distribution facilities, are considered sufficient to meet the present requirements of Aquarion’s customers under normal conditions. On occasion, drought declarations are issued for portions of Aquarion’s service territories in response to extended periods of dry weather conditions.

NUCLEAR FUEL STORAGE

CL&P, NSTAR Electric, PSNH, and several other New England electric utilities are stockholders in three inactive regional nuclear generation companies, CYAPC, MYAPC and YAEC (collectively, the Yankee Companies).  The Yankee Companies have completed the physical decommissioning of their respective nuclear power facilities and are now engaged in the long-term storage of their spent nuclear fuel.  The Yankee Companies fund these costs through litigation proceeds received from the DOE and, to the extent necessary, through wholesale, FERC-approved rates charged under power purchase agreements with several New England utilities, including CL&P, NSTAR Electric and PSNH. CL&P, NSTAR Electric and PSNH, in turn recover these costs from their customers through state regulatory commission-approved retail rates. The Yankee Companies collect amounts that we believe are adequate to recover the remaining plant closure and fuel storage cost estimates for the respective plants. We believe CL&P and NSTAR Electric will recover their shares of these obligations from their customers. PSNH has recovered its total share of these costs from its customers.

We consolidate the assets and obligations of CYAPC and YAEC on our consolidated balance sheet because our ownership and voting interests are greater than 50 percent of each of these companies.

Each of the states in which we do business also has Renewable Portfolio Standards (RPS) requirements, which generally require fixed percentages of our energy supply to come from renewable energy sources such as solar, wind, hydropower, landfill gas, fuel cells and other similar sources.

Connecticut's RPS statute requires increasing percentages of the electricity sold to retail customers to have direct ties to renewable sources. In 2020,2023, the total RPS obligation was 2935.0 percentand will ultimately reach 4848.0 percent in 2030. CL&P is permitted to recover any costs incurred in complying with RPS from its customers through its GSCgeneration service charge rate.

Massachusetts' RPS program requires electricity suppliers to meet renewable energy standards. For 2020,2023, the requirement was 27.71RPS and Clean Energy Standard (CES) requirements were 59.2 percent, and will ultimately reach 39.3163.1 percent in 2025. Massachusetts electric suppliers were also required to meet Alternative Energy Portfolio Standards (APS) of 5.75 percent and Clean Peak Energy Standards (CPS) of 6.0 percent in 2023. Those requirements will reach 6.25 and 9.00 percent in 2025, respectively. NSTAR Electric is permitted to recover any costs incurred in complying with RPSthese requirements from its customers through rates. NSTAR Electric also owns renewable solar power facilities. The RECs generated from NSTAR Electric's solar power facilities are sold to other energy suppliers, and the proceeds from these sales are credited back to customers.

New Hampshire's RPS provision requires increasing percentages of the electricity sold to retail customers to have direct ties to renewable sources. In 2020,2023, the total RPS obligation was 21.723.4 percent and it will ultimately reach 25.2 percent in 2025. The costs of the RECs are recovered by PSNH through rates charged to customers.

Hazardous Materials RegulationsEnvironmental Regulation and Matters

We are subject to various federal, state and local environmental legislation and regulation with respect to water quality, air quality, natural/working lands (wetlands, resource areas, habitat), hazardous materials and other environmental matters. Our environmental policy includes formal procedures and a task-scheduling system in place to help ensure environmental compliance. The Board’s Governance, Environmental and Social Responsibility Committee also provides oversight of climate issues, environmental matters and compliance. We also identify and address potential environmental risks through our Enterprise Risk Management (ERM) program in addition to rigorous audits of our facilities, vendors, and processes.

Additionally, projects may not be constructed or significantly modified without a review of the environmental impact of the proposed construction or modification by the applicable federal or state agencies. Many of our construction projects require the submission of comprehensive permitting applications to various local, state and federal agencies. The permits we receive outline various best management practices and restoration requirements to address construction period-impacts.

We have recorded a liability for what we believe, based upon currently available information, is our reasonably estimable environmental investigation, remediation, and/or Natural Resource Damagesnatural resource damages costs for waste disposal sites for which we have probable liability. Under federal and state law, government agencies and private parties can attempt to impose liability on us for recovery of investigation and remediation costs at hazardous wastecontaminated sites. As of December 31, 2020,2023, the liability recorded for our reasonably estimable and probable environmental remediation costs for known sites needing investigation and/or remediation, exclusive of recoveries from insurance or from third parties, was $102.4$128.2 million, representing 6365 sites. These costs could be significantly higher if additional remediation becomes necessary or when additional information as to the extent of contamination becomes available.

The most significant liabilities currently relate to future clean-up costs at former MGP facilities. These facilities were owned and operated by our predecessor companies from the mid-1800's to mid-1900's. By-products from the manufacture of natural gas using coal resulted in fuel oils, hydrocarbons, coal tar, purifier wastes, metals and other waste products that may pose a potential risk to human health and the environment. We currently have partial or full ownership responsibilities at former MGP sites that have a reserve balance of $92.2$117.1 million of the total $102.4$128.2 million as of December 31, 2020.2023. MGP costs are recoverable through rates charged to our customers.

When planning environmental investigations and remediation of impacted properties, we work closely with the municipalities and environmental regulators to ensure that our remediation plans adhere to applicable regulations while protecting human health and the environment. In many cases, these remediation projects are designed to address opportunities for beneficial reuse of the property.

Global Climate Change and Greenhouse Gas Emission Issues

Eversource assesses the regulatory, physical and transitional impacts related to climate change to develop mitigation strategies including evaluating the impacts of more severe weather events, financial risks, changing customer behaviors, and opportunities to reduce emissions in our operations and for the region through clean energy and emerging technologies investments.

Regulatory Impacts of Climate Change: Global climate change continues to receive increasing focus from the federal and state governments. The Biden administration has communicated a strong focus on addressing climate change by setting a U.S. target of reducing greenhouse gas (GHG) emissions by 50 percent by 2030, compared to 2005 levels, and achieving net-zero emissions by 2050 economy-wide. The plan calls for aggressive measures focused on clean transportation, clean energy and climate investments targeted at environmental justice communities. In support of this plan, federal funding and incentive programs for clean transportation and energy offer opportunities for Eversource to invest in projects that have the ability to reduce emissions in the region while benefiting our communities and shareholders. Similarly, some of the states in which we operate have aggressive climate goals and implementation plans. In Connecticut, legislation includes a target to achieve zero-carbon electricity by 2040. In response to the 2021 Massachusetts climate legislation calling for increased electrification of the transportation and building sectors, in 2023, Eversource developed an Electric Sector Modernization Plan (ESMP) detailing steps the Company will take over the next five and ten years to help ensure reliability and resiliency while supporting a clean energy future. Similarly, the Massachusetts “Future of Gas” docket (DPU 20-80) looks to identify ways for natural gas local distribution companies to support the state’s net zero by 2050 climate goal. These state regulations and related policies may introduce risks and opportunities to our businesses if demands for energy or heating change.

Eversource continually evaluates the evolving regulatory landscape concerning climate change, which could potentially lead to additional requirements and additional rules and regulations that could impact how we operate our businesses. Potential future environmental statutes and regulations, such as additional greenhouse gas reduction regulations to address global climate change, could impose significant additional costs and there can be no assurance that regulators will approve the recovery of those costs.

Physical and Transitional Impacts of Climate Change: Eversource assesses the physical impacts of climate change that are event-driven or due to longer-term shifts in climate patterns, as well as transitional impacts related to a shift to a lower-carbon economy and changes to address mitigation and adaptation requirements. To address physical and transitional impacts related to climate change, maintain resiliency across our system, and enable potential opportunities for our business, we are pursuing the following actions:

Improving our system resiliency in response to climate change through vegetation management, pole and wire strengthening, flood proofing, and other system hardening measures;
Implementing a grid modernization plan that will enhance our electric distribution infrastructure to improve resiliency and reliability and increase opportunities to facilitate integration of distributed energy resources and electric vehicle infrastructure;
Focusing on improving the efficiency of our electric and natural gas distribution systems, preparing for increased opportunities that clean energy advancements create, and providing customers with ways to optimize their energy efficiency;
Investigating emerging technologies such as energy storage and automation programs that improve reliability;
Implementing programs to address risks that may impact water availability and water quality; and
Evaluating opportunities for our natural gas system and exploring alternative, less carbon-intense, technologies like renewable natural gas and geothermal for heating.

Physical risks from climate change may be acute due to increased severity of extreme weather events or chronic due to changes in precipitation patterns and extreme variability in weather patterns, rising mean temperatures and/or rising sea levels, and shifting weather conditions, such as changes in precipitation, extreme heat, more frequent and severe storms, droughts, wildfires and floods. These risks may result in customers’ energy and water usage increasing or decreasing depending on the duration and magnitude of the changes, degradation of water quality and our ability to reliably deliver our services to customers. Severe weather may cause outages, potential disruption of operations, and property damage to our assets.

Our actions to improve system reliability and resiliency allow our business to operate under changing conditions and meet customer expectations. System improvements are designed to withstand severe weather impacts and include installing new and stronger infrastructure like poles, wires and related system equipment, as well as enhanced year-round tree trimming. We are reinforcing existing critical facilities to withstand storm surges and all future substations are being “flood hardened” to better protect our system against storm surges associated with the increasing risk of severe weather. We created our comprehensive emergency preparedness and response plans in partnership with state and community leaders so that when a storm occurs, we can provide customers and municipalities with timely and accurate information, while safely and promptly restoring power. Additionally, we collaborate with other utility providers and industry partners across the country to better understand storm hazards and develop solutions to improve our system reliability.

Eversource has made a corporate commitment to reduce Scope 1 and 2 GHG emissions from our operations and reach carbon neutrality by 2030. In December 2023, we submitted an application to the Science Based Target initiative (SBTi) seeking validation of a broader GHG target, which will expand our emission reduction efforts and include indirect Scope 3 sources. Greenhouse gas emissions from our operations consist primarily of line loss (emissions associated with the energy lost when power is transmitted and distributed across the electric system), methane leaks from our natural gas distribution system, operating our facilities and vehicle fleet, and sulfur hexafluoride (SF6) leaks from electric equipment. To measure our influences on climate change, we quantify and publicly report our operational carbon footprint through a third-party verified GHG emission inventory on an annual basis. Our initiatives to reduce GHG emissions across our company include improving energy efficiency and expanding the use of renewable energy at our buildings, utilizing alternative fuels and introducing more hybrid vehicles into the company fleet, reducing fugitive emissions of methane and SF6 by replacing leak-prone natural gas pipes, improving maintenance of SF6 electrical equipment, and piloting innovative technologies, such as alternative SF6 electrical equipment.
13



Our business is also exposed to climate-related transitional risks, such as policy, legal and reputational impacts, and technology and market changes as we enable broad decarbonization of the electrical and building sectors in support of regional policies and targets. We actively support local, state and federal emission reduction goals to address climate change and pursue climate-related opportunities that enable continued business success while serving the needs of our customers. Our clean energy investments help reduce regional emissions while improving shareholder value. Meanwhile, our energy efficiency solutions and electric vehicle infrastructure investments allow our customers to make choices that minimize climate-related impacts.

Additionally, as our business transitions to support a low carbon economy, human capital needs will also change with the potential to impact our workforce. As new technologies are implemented, we will need to recruit, develop and possibly retrain employees to meet the need for new skill sets.

Electric and Magnetic Fields  

For more than twentyforty years, published reports have discussed the possibility of adverse health effects from electric and magnetic fields (EMF) associated with electric transmission and distribution facilities, andincluding appliances, and wiring in buildings and homes. Although weakSome epidemiology studies have reported a possible statistical association between adverse health risk associations reportedeffects and exposure with EMF. The association identified in some epidemiologyof these studies remain unexplained most researchers, as well as numerousand inconclusive. Numerous scientific review panels, considering all significant EMF epidemiology and laboratory studies, have concluded that the available body of scientific information does not support thea conclusion that EMF affects human health.

health at levels expected in the vicinity. In accordance with recommendations of various regulatory bodies and public health organizations, we use design principles that help reduce potential EMF exposures associated with new transmission lineslines.

HUMAN CAPITAL

Item 1A.Risk Factors

Global climate changeIn addition to the matters set forth under "Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995" included immediately prior to Item 1,Business,above, we are subject to a variety of material risks. Our susceptibility to certain risks, including those discussed in detail below, could exacerbate other risks. These risk factors should be considered carefully in evaluating our risk profile. There may be additional risks and greenhouseuncertainties (either currently unknown or not currently believed to be material) that could adversely affect our financial position, results of operations, and cash flows.

Cybersecurity Threats and Attacks:

Cyberattacks, including acts of war or terrorism, targeted directly on or indirectly affecting our systems or the systems of third parties on which we rely, could severely impair operations, negatively impact our business, lead to the disclosure of confidential information and adversely affect our reputation.

Cyberattacks that seek to exploit potential vulnerabilities in the utility industry and seek to disrupt electric, natural gas emission issuesand water transmission and distribution systems are increasing in sophistication, magnitude and frequency. Various geo-political conflicts and acts of war around the world continue to result in increased cyberattacks against critical infrastructure. A successful cyberattack on the information technology systems that control our transmission, distribution, natural gas and water systems or other assets could impair or prevent us from managing these systems and facilities, operating our systems effectively, or properly managing our data, networks and programs. The breach of certain information technology systems could adversely affect our ability to correctly record, process and report financial information. A major cyber incident could result in significant expenses to investigate and to repair system damage or security breaches and could lead to litigation, fines, other remedial action, heightened regulatory scrutiny and damage to our reputation.

We have received an increased focusinstituted safeguards to protect our information technology systems and assets. We deploy substantial technologies to system and application security, encryption and other measures to protect our computer systems and infrastructure from state governmentsunauthorized access or misuse. Specifically, regarding vulnerabilities, we patch systems where patches are available to deploy, and have technologies that detect exploits of vulnerabilities and proactively block the exploit when it happens. We also interface with numerous external entities to improve our cybersecurity situational awareness. The FERC, through the North American Electric Reliability Corporation (NERC), requires certain safeguards to be implemented to deter cyberattacks. These safeguards may not always be effective due to the evolving nature of cyberattacks. We maintain cyber insurance to cover damages, potential ransom and defense costs related to breaches of networks or operational technology, but it may be insufficient in limits and coverage exclusions to cover all losses.

Any such cyberattacks could result in loss of service to customers and a significant decrease in revenues, which could have a material adverse impact on our financial position, results of operations and cash flows.

For further information, see Item 1C, Cybersecurity included in this Annual Report on Form 10-K.

The unauthorized access to, and the misappropriation of, confidential and proprietary Company, customer, employee, financial or system operating information could adversely affect our business operations and adversely impact our reputation.

In the regular course of business, we, and our third-party suppliers, rely on information technology to maintain sensitive Company, customer, employee, financial and system operating information. We are required by various federal government.and state laws to safeguard this information. Cyber intrusions, security breaches, theft or loss of this information by cybercrime or otherwise could lead to the release of critical operating information or confidential Company, customer or employee information, which could adversely affect our business operations or adversely impact our reputation, and could result in significant costs, fines and litigation. We employ system controls to prevent the dissemination of certain confidential information and periodically train employees on phishing risks. We maintain cyber insurance to cover damages, potential ransom and defense costs arising from unauthorized disclosure of, or failure to protect, private information, as well as costs for notification to, or for credit monitoring of, customers, employees and other persons in the event of a breach of private information. This insurance covers amounts paid to address a network attack or the disclosure of personal information, and costs of a qualified forensics firm to determine the cause, source and extent of a network attack or to investigate, examine and analyze our network to find the cause, source and extent of a data breach, but it may be insufficient to cover all losses. While we have implemented measures designed to prevent network attacks and mitigate their effects should they occur, these measures may not be effective due to the continually evolving nature of efforts to access confidential information.

Offshore Wind Business Risk:

Our financial position and future results could be materially adversely affected if we are unable to sell our 50 percent interests in three offshore wind projects on the timelines, terms and pricing we expect, if we and the counterparties are unable to satisfy all closing conditions and consummate the purchase and sale transactions with respect to our offshore wind assets, if Sunrise Wind does not win in the OREC contract solicitation process, if we are unable to qualify for investment tax credits related to these projects, if we experience variability in the projected construction costs of the offshore wind projects, if there is a deterioration of market conditions in the offshore wind industry, and if the projects do not commence operation as scheduled or within budget or are not completed.

16


Our offshore wind business includes 50 percent ownership interests in three jointly-owned offshore wind projects being developed and constructed. The EPA initiateddevelopment and construction of these offshore wind electric generation facilities involves numerous significant risks including meeting construction schedules, federal, state and local permitting and regulatory approval processes, scheduling or permitting delays, cost overruns, higher interest rates, tax strategies and changes to federal tax laws impacting the offshore wind partnership’s ability to monetize tax attributes, new legislation impacting the industry, the cancellation of any projects, and actions of our strategic partner. Operational risks of these offshore wind electric generation facilities include maintaining continuing interconnection arrangements, power purchase agreements, or other market mechanisms, as well as interconnecting utility and Regional Transmission Organizations rules, policies, procedures and FERC tariffs that permit future offshore wind project operations, and capacity factors once projects are placed in operation. These risks could impact our offshore wind partnership’s ability to generate returns from its offshore wind projects and result in lower investment returns.

We have entered into agreements to sell our interest in the three offshore wind projects, however we may be unable to complete the sales of these projects on the timelines and for the sales value we expect. If the ultimate sales value of our interest in these projects is lower than expected, or we are unable to sell our interests, it could have an adverse effect on our financial condition and results of operations. The sales agreements are subject to certain regulatory approvals as well as other conditions, and we may be unable to satisfy all closing conditions necessary to consummate the purchase and sale transactions. The purchaser of the Revolution Wind and South Fork Wind projects may be unable to reach a rulemaking addressing greenhousepartnership agreement with Ørsted, which is a condition of closing that transaction. The sale of the Sunrise Wind project to Ørsted is dependent on the successful outcome of Sunrise Wind’s re-bidding process of its OREC contract in the New York solicitation. If Sunrise Wind were to lose to a competing bid in the New York solicitation, then the existing OREC contract for Sunrise Wind will be cancelled according to the state’s requirements, and Eversource and Ørsted’s joint venture for Sunrise Wind will remain in place. That scenario could adversely impact the ability to sell the Sunrise Wind project in the future, and could result in the project to be abandoned. If the Sunrise Wind project were to be abandoned, there would be cancellation and other abandonment costs incurred, and those costs could be above amounts already assumed in our impairment evaluation and reflected in the current fair value on our balance sheet, which could have an adverse effect on our financial condition and results of operations.

Future cash flows resulting from the expected sales are also impacted by the ability to qualify the Revolution Wind project for investment tax credit adders, as included in the Inflation Reduction Act. Evaluating the project’s qualifications to achieve these investment tax credit adders requires significant judgment, and we may be unable to meet these qualifications. Additionally, for Revolution Wind and South Fork Wind, there could be cost overruns on the projects through each project's respective commercial operation date, which would not be recovered in the expected sales price and other potential future payments to maintain transaction economics required of Eversource. Amounts incurred above those that have already been assumed in our impairment evaluation and reflected in the current fair value on our balance sheet would adversely impact our financial position, results of operations and cash flows.

These risks could adversely affect the ultimate value of the wind projects and result in an additional, significant impairment in a future period, which could have a material adverse effect on our financial condition and results of operations. Lower-than-expected sales prices, or the inability to sell the wind projects, could also result in liquidity issues, negatively impact certain of our financial metrics and operations plan, or could result in a downgrade in our credit rating, which could increase our cost of borrowing and cost of capital or restrict our ability to access the capital markets.

Regulatory, Legislative and Compliance Risks:

The actions of regulators and legislators could result in outcomes that may adversely affect our earnings and liquidity.

The rates that our electric, natural gas emissions and water companies charge their customers are determined by their state regulatory commissions. These commissions also regulate the companies' accounting, operations, the issuance of certain securities and certain other matters. The FERC regulates the transmission of electric energy, the sale of electric energy at wholesale, accounting, issuance of certain securities and certain other matters, including reliability standards through the NERC. The regulatory process may be adversely affected by the political, regulatory and economic environment in 2009,the states in which we operate.

Under state and federal law, our electric, natural gas and water companies are entitled to charge rates that are sufficient to allow them an opportunity to recover their prudently incurred operating and capital costs and a reasonable rate of return on invested capital, to attract needed capital and maintain their financial integrity, while also protecting relevant public interests. Our electric, natural gas and water companies are required to engage in regulatory approval proceedings as a part of the process of establishing the terms and rates for their respective services. Each of these companies prepares and submits periodic rate filings with their respective state regulatory commissions for review and approval, which allows for various entities to challenge our current or future rates, structures or mechanisms and could alter or limit the rates we are allowed to charge our customers. These proceedings typically involve multiple parties, including governmental bodies and officials, consumer advocacy groups, and various consumers of energy, who have differing concerns. Any change in rates, including changes in allowed rate of return, are subject to regulatory approval proceedings that can be contentious, lengthy, and subject to appeal. This may lead to uncertainty as to the ultimate result of those proceedings. Established rates are also subject to subsequent prudency reviews by state regulators, whereby various portions of rates could be adjusted, subject to refund or disallowed, including cost recovery mechanisms. The ultimate outcome and timing of regulatory rate proceedings, or challenges to certain provisions in our distribution tariffs could have a significant effect on our ability to recover costs or earn an adequate return. Adverse decisions in our proceedings could adversely affect our financial position, results of operations and cash flows. We continue to experience challenges related to the regulatory environment in Connecticut with respect to our electric distribution, natural gas, and water businesses.

17


The federal, state and local political and economic environment currently has, and may in the future have, an adverse effect on regulatory decisions with negative consequences for us. These decisions may require us to cancel, reduce, or delay planned development activities or other planned capital expenditures or investments or otherwise incur costs that we may not be able to recover through rates. There can be no assurance that regulators will approve the recovery of all costs incurred by our electric, natural gas and water companies, including costs for construction, operation and maintenance, and storm restoration. The inability to recover a significant amount of operating costs could have an adverse effect on our financial position, results of operations, and cash flows. Changes to rates may occur at times different from when costs are incurred. Additionally, catastrophic events at other utilities could result in our regulators and legislators imposing additional requirements that may lead to additional costs for the companies. In addition to the risk of disallowance of incurred costs, regulators may also impose downward adjustments in a company’s allowed ROE as well as assess penalties and fines. These actions would have an adverse effect on our financial position, results of operations and cash flows.

The FERC has jurisdiction over our transmission costs recovery and our allowed ROEs. If FERC changes its methodology on developing ROEs, there could be a negative impact on our results of operations and cash flows. Additionally, certain outside parties have filed four complaints against transmission-owning electric companies within ISO-NE alleging that our allowed ROEs are unjust and unreasonable. An adverse decision in any of these four complaints could adversely affect our financial position, results of operations and cash flows.

The FERC also has jurisdiction over our transmission rate incentives such as the regional transmission organization (RTO) participation ROE incentive adder, CWIP in rate base incentive and the abandoned plant incentive. If the FERC changes its policies regarding these incentives, there could be a negative impact on our financial position, results of operations and cash flows. Additionally, the FERC issued a findingSupplemental Notice of Proposed Rulemaking (NOPR) on Transmission Incentives that concludedproposes to eliminate the existing RTO ROE incentive adder for utilities that greenhouse gas emissions are "air pollution" that endangers public healthhave been participating in an RTO for more than three years. A FERC decision approving this proposal could adversely affect our financial position, results of operations and welfarecash flows.

FERC's policy has encouraged competition for transmission projects, even within existing service territories of electric companies, as it looks to expand the transmission system to accommodate state and should be regulated.  The EPA has mandated greenhouse gas emission reporting beginningfederal policy goals to utilize more renewable energy resources as well as to enhance reliability and resilience for extreme weather events. Implementation of FERC's goals, including within our service territories, may expose us to competition for construction of transmission projects, additional regulatory considerations, and potential delay with respect to future transmission projects, which may adversely affect our results of operations and lower rate base growth.

Changes in 2011 for emissions for certain aspectstax laws, as well as the potential tax effects of business decisions could negatively impact our business, including volumeresults of gas supplied to large customersoperations, financial condition and fugitive emissions of SF6 gas and methane.cash flows.

We are continually evaluatingexposed to significant reputational risks, which make us vulnerable to increased regulatory oversight or other sanctions.

Because utility companies, including our electric, natural gas and water utility subsidiaries, have large customer bases, they are subject to adverse publicity focused on the reliability of their distribution services and the speed with which they are able to respond to electric outages, natural gas leaks and similar interruptions caused by storm damage or other unanticipated events, including those related to climate change. Adverse publicity of this nature could harm our reputation and the reputation of our subsidiaries; may make state legislatures, utility commissions and other regulatory risksauthorities less likely to view us in a favorable light; and may cause us to be subject to less favorable legislative and regulatory uncertainty presentedoutcomes, legal claims or increased regulatory oversight. Unfavorable regulatory outcomes can include more stringent laws and regulations governing our operations, such as reliability and customer service quality standards or vegetation management requirements, as well as fines, penalties or other sanctions or requirements. Further, we rely upon purchased power and purchased natural gas supply from third parties to meet customers’ energy requirements.Due to a variety of factors, including the inflationary economic environment, geo-political conflicts, and increased customer energy demand, the cost of energy supply in New England remains high. We also may be required to implement rolling blackouts by ISO-NE, the region’s independent grid operator if enough capacity is not available in the area to meet peak demand needs. The significant supply cost increases, as well as any failure to meet customer energy requirements, could negatively impact the satisfaction of our customers and our customers’ ability to pay their utility bills, which could have an adverse impact on our business, reputation, financial position, results of operations and cash flows.

Addressing any adverse publicity, regulatory scrutiny or enforcement or other legal proceedings is time consuming and expensive and, regardless of the factual basis for the assertions being made, can have a negative impact on the reputation of our business, on the morale and performance of our employees and on our relationships with respective regulators, customers and counterparties. We are unable to predict future legislative or regulatory changes, initiatives or interpretations or other legal proceedings, and there can be no assurance that we will be able to respond adequately to such actions. The direct and indirect effects of negative publicity, and the demands of responding to and addressing it, may have a material adverse effect on our financial position, results of operations and cash flows.

Costs of compliance with environmental laws and regulations, including those related to climate change, concerns.  Such concerns could potentially leadmay increase and have an adverse effect on our business and results of operations.

Our subsidiaries’ operations are subject to additionalextensive and increasing federal, state and local environmental statutes, rules and regulations that govern, among other things, water quality (including treatment of PFAS (Per- and Polyfluoroalkyl Substances) and lead), water discharges, the management of hazardous material and solid waste, and air emissions. Compliance with these requirements requires us to incur significant costs relating to environmental permitting, monitoring, maintenance and upgrading of facilities, remediation, and reporting. For our water business, compliance with proposed water quality regulations, including those for PFAS and lead, could require the construction of facilities and replacement of customer lead service lines, respectively.

18


The costs of compliance with existing legal requirements or legal requirements not yet adopted may increase in the future. Although we have recorded liabilities for known environmental obligations, these costs can be difficult to estimate due to uncertainties about the extent of contamination, remediation alternatives, the remediation levels required by state and federal agencies, and the financial ability of other potentially responsible parties. An increase in such costs, unless promptly recovered, could have an adverse impact howon our business and our financial position, results of operations and cash flows.

For further information, see Item 1,BusinessOther Regulatory and Environmental Matters, included in this Annual Report on Form 10-K.

Risks Related to the Environment and Catastrophic Events:

The effects of climate change, including severe storms, could cause significant damage to any of our facilities requiring extensive expenditures, the recovery for which is subject to approval by regulators.

Climate change creates physical and financial risks to our operations. Physical risks from climate change may include an increase in sea levels and changes in weather conditions, such as changes in precipitation, extreme heat and extreme weather events. Customers’ energy and water needs vary with weather conditions, primarily temperature and humidity. For residential customers, heating and cooling represent their largest energy use. For water customers, conservation measures imposed by the communities we operateserve could impact water usage. To the extent weather conditions are affected by climate change, customers’ energy and water usage could increase or decrease depending on the duration and magnitude of the changes.

Severe weather induced by climate change, such as extreme and frequent ice and snow storms, tornadoes, micro-bursts, hurricanes, floods, droughts, wildfires, and other natural disasters, may cause outages and property damage, which may require us to incur additional costs that may not be recoverable from customers. The cost of repairing damage to our general utilityoperating subsidiaries' facilities and the potential disruption of their operations due to storms, natural disasters or other catastrophic events could be substantial, particularly as regulators and customers demand better and quicker response times to outages. If, upon review, any of our state regulatory authorities finds that our actions were imprudent, some of those restoration costs may not be recoverable from customers and could result in penalties or fines. The inability to recover a significant amount of such costs could have an adverse effect on our financial position, results of operations and cash flows. We maintain property insurance, but it may be insufficient in limits and coverage exclusions to cover all losses. Additionally, these types of weather events risk interruption of the supply chain and could disrupt the delivery of goods and services required for our operations.

Transitional impacts related to climate change may have an adverse effect on our business and results of operations due to costs associated with new technologies, evolving customer expectations and changing workforce needs.

Initiatives to mitigate the impacts of climate change, support a transition to cleaner energy, and reduce emissions, may have a material adverse financial impact to our business. These couldimpacts include federal "capthe costs associated with the development and trade" laws, carbon taxes,implementation of new technologies to maintain system reliability and fuelresiliency and lower emissions, including grid modernization and energy taxes.storage. An increase in such costs, unless promptly recovered, could have an adverse impact on our financial position, results of operations and cash flows. There may also be financial and reputational risks if we fail to meet evolving customer expectations, including enabling the integration of residential renewables and providing low carbon solutions, such as electric vehicle infrastructure and energy efficiency services. Additionally, actions to mitigate climate change may result in a transition in our workforce that must adapt to meet the need for new job skills. Associated costs include training programs for existing employees and workforce development as we transition to new technologies and clean energy solutions.

Adequacy of water supplies and contamination of our water supplies, the failure of dams on reservoirs providing water to our customers, or requirements to repair, upgrade or dismantle any of these dams, may disrupt our ability to distribute water to our customers and result in substantial additional costs, which could adversely affect our financial position, results of operations and cash flows.

Our water business faces an inherent strategic risk related to adequacy of supply (i.e., water scarcity). Water scarcity risk is heightened by multiple factors. We expect that any costsclimate change will cause both an increase in demand due to increasing temperatures and a potential for a decrease of these rulesavailable supply due to shifting rainfall and recharge patterns. Regulatory constraints also present challenges to permit new sources of supply in the region. In Connecticut, where the vast majority of our dams are located, impounded waterways are required to release minimum downstream flow. New regulations would be recovered from customers.are being phased into effect over the next one to five years that will increase the volume of downstream releases required across our Connecticut service territory, depleting the volume of supply in storage that is used to meet customer demands. This combination of factors may cause an increased likelihood of drought emergencies and water use restrictions that could adversely affect our ability to provide water to our customers, and reputational/brand damage that could negatively impact our water business.

Our water supplies, including water provided to our customers, are also subject to possible contamination from naturally occurring compounds and elements or non-organic substances, including PFAS and lead. Our water systems include impounding dams and reservoirs of various sizes. Although we believe our dams are structurally sound and well-maintained, significant damage to these facilities, or a significant decrease in the water in our reservoirs, could adversely affect our ability to provide water to our customers until the facilities and a sufficient amount of water in our reservoirs can be restored. A failure of a dam could result in personal injuries and downstream property damage for which we may be liable. The failure of a dam would also adversely affect our ability to supply water in sufficient quantities to our customers. Any losses or liabilities incurred due to a failure of one of our dams may not be recoverable in rates and may have a material adverse effect on our financial position, results of operations and cash flows. We maintain liability insurance, but it may be insufficient in limits and coverage exclusions to cover all losses.

19


Physical attacks, including acts of war or terrorism, both threatened and actual, could adversely affect our ability to operate our systems and could adversely affect our financial results and liquidity.

Physical attacks, including acts of war or terrorism, both threatened and actual, that damage our transmission and distribution systems or other assets could negatively impact our ability to transmit or distribute energy, water, natural gas, or operate our systems efficiently or at all. Because our electric transmission systems are part of an interconnected regional grid, we face the risk of widespread blackouts due to grid disturbances or disruptions on a neighboring interconnected system. Similarly, our natural gas distribution system is connected to transmission pipelines not owned by Eversource. If there was an attack on the transmission pipelines, it could impact our ability to deliver natural gas. If our assets were physically damaged and were not recovered in a timely manner, it could result in a loss of service to customers, a significant decrease in revenues, significant expense to repair system damage, costs associated with governmental actions in response to such attacks, and liability claims, all of which could have a material adverse impact on our financial position, results of operations and cash flows. We maintain property and liability insurance, but it may be insufficient in limits and coverage exclusions to cover all losses. In addition, physical attacks against third-party providers could have a similar effect on the operation of our systems.

Business and Operational Risks:

Strategic development or investment opportunities in electric transmission, distributed generation, or clean-energy technologies may not be successful, which could have a material adverse effect on our business prospects.

We are pursuing investment opportunities in electric transmission facilities, distributed generation and other clean-energy infrastructure, including interconnection facilities. The development of these projects involve numerous significant risks including federal, state and local permitting and regulatory approval processes, scheduling or permitting delays, increased costs, tax strategies and changes to federal tax laws, new legislation impacting the industry, economic events or factors, environmental and community concerns, design and siting issues, difficulties in obtaining required rights of way, and competition from incumbent utilities and other entities. Also, supply constraints in New England have led to significant increases in commodity costs which may impact our ability to accomplish our strategic objectives. Further, regional clean energy goals may not be achieved if local, state, and federal policy is not in alignment with integrated planning of our infrastructure investments.

Our transmission and distribution systems may not operate as expected, and could require unplanned expenditures, which could adversely affect our financial position, results of operations and cash flows.

Our ability to properly operate our transmission and distribution systems is critical to the financial performance of our business. Our transmission and distribution businesses face several operational risks, including the breakdown, failure of, or damage to operating equipment, information technology systems, or processes, especially due to age; labor disputes; disruptions in the delivery of electricity, natural gas and water; increased capital expenditure requirements, including those due to environmental regulation; catastrophic events resulting from equipment failures such as wildfires and explosions, or external events such as a solar event, an electromagnetic event, or other similar occurrences; increasingly severe weather conditions due to climate change beyond equipment and plant design capacity; human error; global supply chain disruptions; and potential claims for property damage or personal injuries beyond the scope of our insurance coverage. Many of our transmission projects are expected to alleviate identified reliability issues and reduce customers' costs. However, if the in-service date for one or more of these projects is delayed due to economic events or factors, or regulatory or other delays, including permitting and siting, the risk of failures in the electric transmission system may increase. We also implement new information technology systems from time to time, which may disrupt operations. Any failure of our transmission and distribution systems to operate as planned may result in increased capital costs, reduced earnings or unplanned increases in operations and maintenance costs. The inability to recover a significant amount of such costs could have an adverse effect on our financial position, results of operations and cash flows.

New technology and alternative energy sources could adversely affect our operations and financial results.

Advances in technology that reduce the costs of alternative methods of producing electric energy to a level that is competitive with that of current electric production methods, could result in loss of market share and customers, and may require us to make significant expenditures to remain competitive. These changes in technology, including micro-grids and advances in energy or battery storage, could also alter the channels through which electric customers buy or utilize energy, which could reduce our revenues or increase our expenses. Economic downturns or periods of high energy supply costs typically can lead to the development of legislative and regulatory policy designed to promote reductions in energy consumption and increased energy efficiency and self-generation by customers. Additionally, in response to risks posed by climate change, we may need to make investments in our system including upgrades or retrofits to meet enhanced design criteria, which can incur additional costs over conventional solutions.

We rely on third-party suppliers for equipment, materials, and services and we outsource certain business functions to third-party suppliers and service providers, and substandard performance or inability to fulfill obligations by those third parties could harm our business, reputation and results of operations.

We outsource certain services to third parties in areas including information technology, transaction processing, human resources, payroll and payroll processing and certain operational areas. Outsourcing of services to third parties could expose us to substandard quality of service delivery or substandard deliverables, which may result in missed deadlines or other timeliness issues, non-compliance (including with applicable legal requirements and industry standards) or reputational harm, which could negatively impact our results of operations. Our contractual arrangements with these contractors typically include performance standards, progress payments, insurance requirements and security for performance. The global supply chain of goods and services remains volatile, and as a result, we are seeing delivery delays of certain goods, particularly certain types
20


of transformers. If significant difficulties in the global supply chain cycle or inflationary impacts were to worsen, they could adversely affect our results of operations, or adversely affect our ability to work with regulators, unions, customers or employees.

The loss of key personnel, the inability to hire and retain qualified employees, or the failure to maintain a positive relationship with our workforce could have an adverse effect on our business, financial position and results of operations.

Our operations depend on the continued efforts of our employees. Retaining key employees and maintaining the ability to attract new employees are important to both our operational and financial performance. We cannot guarantee that any member of our management or any key employee at the Eversource parent or subsidiary level will continue to serve in any capacity for any particular period of time. Our workforce in our subsidiaries includes many workers with highly specialized skills maintaining and servicing the electric, natural gas and water infrastructure that cannot be quickly replaced due to the technically complex work they perform. We have developed strategic workforce plans to identify key functions and proactively implement plans to assure a ready and qualified workforce, but we cannot predict the impact of these plans on our ability to hire and retain key employees. Labor disputes, work stoppages or an inability to negotiate future collective bargaining agreements on commercially reasonable terms, as well as the increased competition for talent or the intentional misconduct of employees or contractors, may also have an adverse effect on our business, financial position and results of operations.

Financial, Economic, and Market Risks:

Limits on our access to, or increases in, the cost of capital may adversely impact our ability to execute our business plan.

We use short-term debt and the long-term capital markets as a significant source of liquidity and funding for capital requirements not obtained from our operating cash flow. If access to these sources of liquidity becomes constrained, our ability to implement our business strategy could be adversely affected. In addition, interest rates have increased and may continue to increase in the future. As a result, interest rates on future credit facilities and debt offerings could be higher than current levels, causing our financing costs to increase accordingly, which could adversely impact our financial position, results of operations and cash flows. A downgrade of our credit ratings or events beyond our control, such as a disruption in global capital and credit markets, could increase our cost of borrowing and cost of capital or restrict our ability to access the capital markets and negatively affect our ability to maintain and to expand our businesses.

Market performance or changes in assumptions may require us to make significant contributions to our pension and other postretirement benefit plans.

We provide a defined benefit pension plan and other postretirement benefits for a substantial number of employees, former employees and retirees. Our future pension obligations, costs and liabilities are highly dependent on a variety of factors, many of which are beyond our control. These factors include estimated investment returns, interest rates, discount rates, health care cost trends, benefit changes, salary increases and the demographics of plan participants. If our assumptions prove to be inaccurate, our future costs could increase significantly.In addition, various factors, including underperformance of plan investments and changes in law or regulation, could increase the amount of contributions required to fund our pension plan in the future. Additional large funding requirements, when combined with the financing requirements of our construction program, could impact the timing, amounts, and number of future financings and negatively affect our financial position, results of operations and cash flows.

Goodwill, investments in equity method investments, and long-lived assets if impaired and written down, could adversely affect our future operating results and total capitalization.

We have a significant amount of goodwill on our consolidated balance sheet, which, as of December 31, 2023, totaled $4.53 billion. The carrying value of goodwill represents the fair value of an acquired business in excess of the fair value of identifiable assets and liabilities as of the acquisition date. We test our goodwill balances for impairment on an annual basis or whenever events occur, or circumstances change that would indicate a potential for impairment. A determination that goodwill is deemed to be impaired would result in a non-cash charge that could materially adversely affect our financial position, results of operations and total capitalization.

We assess our investments (recorded as either long-lived assets or equity method investments) for impairment whenever events or circumstances indicate that the carrying amount of the investment may not be recoverable. To the extent the value of the investment becomes impaired, the impairment charge could have a material adverse effect on our financial condition and results of operations.

Our counterparties may not meet their obligations to us or may elect to exercise their termination rights, which could adversely affect our earnings.

We are exposed to the risk that counterparties to various arrangements that owe us money, have contracted to supply us with energy or other commodities or services, or that work with us as strategic partners, including on significant capital projects, will not be able to perform their obligations, will terminate such arrangements or, with respect to our credit facilities, fail to honor their commitments. Should any of these counterparties fail to perform their obligations or terminate such arrangements, we might be forced to replace the underlying commitment at higher market prices and/or have to delay the completion of, or cancel, a capital project. Should any lenders under our credit facilities fail to perform, the level of borrowing capacity under those arrangements could decrease. In any such events, our financial position, results of operations, or cash flows could be adversely affected.

As a holding company with no revenue-generating operations, Eversource parent's liquidity is dependent on dividends from its subsidiaries, its commercial paper program, and its ability to access the long-term debt and equity capital markets.

Eversource parent is a holding company and as such, has no revenue-generating operations of its own. Its ability to meet its debt service obligations and to pay dividends on its common shares is largely dependent on the ability of its subsidiaries to pay dividends to, or repay borrowings from, Eversource parent, and/or Eversource parent's ability to access its commercial paper program or the long-term debt and equity capital markets. Prior to funding Eversource parent, the subsidiary companies have financial obligations that must be satisfied, including among others, their operating expenses, debt service, preferred dividends of certain subsidiaries, and obligations to trade creditors. Should the subsidiary companies not be able to pay dividends or repay funds due to Eversource parent, or if Eversource parent cannot access its commercial paper programs or the long-term debt and equity capital markets, Eversource parent's ability to pay interest, dividends and its own debt obligations would be restricted.

Item 1B.    Unresolved Staff Comments

We do not have any unresolved SEC staff comments.

Item 1C. Cybersecurity

The Company’s policies, practices and technologies allow it to protect its information systems and operational assets from threats. The Board of Trustees and its Finance and Audit Committees continue to provide substantial and focused attention to cyber and system security. The Finance Committee of the Board of Trustees is responsible for oversight of the Company’s enterprise-wide risks, including risks associated with cyber and physical security, and the Company’s programs and practices to monitor and mitigate these risks.

Management prepares comprehensive cyber security reports that are discussed at each meeting of the Finance Committee. The reports focus on the changing threat landscape and the risks to the Company, describe Eversource’s cyber security drills and exercises, attempted and actual breaches on our systems, cyber incidents within the utility industry and around the world, and mitigation strategies. In addition, third-party experts of cyber security risks provide periodic assessments to the utility industry and the Company in particular to the Finance Committee. The Company regularly reviews and updates its cyber and system security programs, and the Finance Committee continues to enhance its robust oversight activities, including meetings with financial, information technology, legal and accounting management, other members of the Board, representatives of the Company’s independent registered public accounting firm, and outside advisors and experts in cyber security risks, at which cyber and system security programs and issues that might affect the Company’s financial statements and operational systems are discussed.

The Company has a robust Enterprise Risk Management Program which has identified cyber security as a top enterprise risk. The managing and monitoring of risks are the responsibility of the Company’s Risk Committee, which meets quarterly and is chaired by the Chief Financial Officer.

The Company is committed to continuous monitoring and assessment of cyber security controls. The Chief Information Security Officer is responsible for developing, implementing, and enforcing our cyber security program and information security policies to protect the Company’s information systems and operational assets. The Chief Information Security Officer position requires at least 15 years of relevant information security experience and relevant security certifications. The Chief Information Security Officer reports directly to the Chief Information Officer and provides regular updates to the executive management team. Our Chief Information Security Officer has over 20 years of relevant experience.

The Company created a Cyber Governance Committee, which includes the Chief Information Security Officer, Chief Information Technology Officer, Chief Accounting Officer, members of the executive management team, and other assurance functions such as Corporate Compliance, Enterprise Risk Management, and Internal Audit.

To assess, identify and manage material risks from cybersecurity threats and to prevent, detect, mitigate and remediate a cyber security or ransomware incident, the following key processes and programs have been implemented and are performed by the Company’s Cyber Security Group, which is overseen by the Chief Information Security Officer:

Implementation of security solutions and standards based on industry best practices to prevent unauthorized access. The Company’s cyber program has been modeled after the National Institute of Standards and Technology framework; a widely accepted framework utilized by critical infrastructure industries.
Periodic external assessments, including outside system access testing, are performed. Rigorous auditing of all safeguards is performed on a regular basis. Risk assessments are held to identify and address new and changing risks to protect systems and sensitive data. Identified areas are monitored and improvements are implemented.
Eversource participates in information sharing programs both within and outside the utility industry, including with the U.S. government and industry organizations, to be able to identify and respond to emerging threats.
The Company maintains current incident response and business continuity plans, which are periodically updated and tested.
Network activity is monitored on an ongoing basis.
Anti-phishing and malware tools are utilized and assessed.
Employees are trained to recognize phishing attempts and are periodically tested. Results of phishing testing are benchmarked against other companies both within and outside the utility industry.

22


Specific to third parties, Eversource has implemented formal screening processes for any applicable vendors by the Company’s Cyber Security Group as part of the Procurement process. The vendors are risk ranked based on the type of work being performed. Periodic rescreening is performed on critical vendors. Vendors are required to attest to their business continuity programs and provide evidence of appropriate insurance and indemnification agreements. The Company bars sourcing from countries included on the Department of Homeland Security’s list of Prohibited Nations to further protect the Company’s supply chain. The Company maintains cyber insurance which covers breaches of networks and operational technology. Our existing insurance limits may be inadequate to cover a material cyber incident. This could expose us to potentially significant claims and damages.

As of December 31, 2023, there were no risks from cybersecurity threats, including due to any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the Company, its business strategy, results of operations, or financial condition.

Item 1A.Risk Factors

In addition to the matters set forth under "Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995" included immediately prior to Item 1,Business,above, we are subject to a variety of material risks. Our susceptibility to certain risks, including those discussed in detail below, could exacerbate other risks. These risk factors should be considered carefully in evaluating our risk profile. There may be additional risks and uncertainties (either currently unknown or not currently believed to be material) that could adversely affect our financial position, results of operations, and cash flows.

Cybersecurity Threats and Attacks:

Cyberattacks, including acts of war or terrorism, targeted directly on or indirectly affecting our systems or the systems of third parties on which we rely, could severely impair operations, negatively impact our business, lead to the disclosure of confidential information and adversely affect our reputation.

Cyberattacks that seek to exploit potential vulnerabilities in the utility industry and seek to disrupt electric, natural gas and water transmission and distribution systems are increasing in sophistication, magnitude and frequency. Various geo-political conflicts and acts of war around the world continue to result in increased cyberattacks against critical infrastructure. A successful cyberattack on the information technology systems that control our transmission, distribution, natural gas and water systems or other assets could impair or prevent us from managing these systems and facilities, operating our systems effectively, or properly managing our data, networks and programs. The breach of certain information technology systems could adversely affect our ability to correctly record, process and report financial information. A major cyber incident could result in significant expenses to investigate and to repair system damage or security breaches and could lead to litigation, fines, other remedial action, heightened regulatory scrutiny and damage to our reputation.

We have instituted safeguards to protect our information technology systems and assets. We deploy substantial technologies to system and application security, encryption and other measures to protect our computer systems and infrastructure from unauthorized access or misuse. Specifically, regarding vulnerabilities, we patch systems where patches are available to deploy, and have technologies that detect exploits of vulnerabilities and proactively block the exploit when it happens. We also interface with numerous external entities to improve our cybersecurity situational awareness. The FERC, through the North American Electric Reliability Corporation (NERC), requires certain safeguards to be implemented to deter cyberattacks. These safeguards may not always be effective due to the evolving nature of cyberattacks. We maintain cyber insurance to cover damages, potential ransom and defense costs related to breaches of networks or operational technology, but it may be insufficient in limits and coverage exclusions to cover all losses.

Any such cyberattacks could result in loss of service to customers and a significant decrease in revenues, which could have a material adverse impact on our financial position, results of operations and cash flows.

Diversity & Inclusion.Our offshore wind business includes 50 percent ownership interests in three jointly-owned offshore wind projects being developed and constructed. The development and construction of these offshore wind electric generation facilities involves numerous significant risks including meeting construction schedules, federal, state and local permitting and regulatory approval processes, scheduling or permitting delays, cost overruns, higher interest rates, tax strategies and changes to federal tax laws impacting the offshore wind partnership’s ability to monetize tax attributes, new legislation impacting the industry, the cancellation of any projects, and actions of our strategic partner. Operational risks of these offshore wind electric generation facilities include Our commitmentmaintaining continuing interconnection arrangements, power purchase agreements, or other market mechanisms, as well as interconnecting utility and Regional Transmission Organizations rules, policies, procedures and FERC tariffs that permit future offshore wind project operations, and capacity factors once projects are placed in operation. These risks could impact our offshore wind partnership’s ability to Diversity & Inclusion (D&I) is critical to building a diverse, empoweredgenerate returns from its offshore wind projects and engaged team that delivers great service safely to our customers.

Additionally, our leadership behaviors underscore the importance of creating inclusive teams, where employees’ voices and contributions are essential to delivering superior customer service.lower investment returns.

Eversource’s executive leadership team promotesWe have entered into agreements to sell our interest in the three offshore wind projects, however we may be unable to complete the sales of these projects on the timelines and supports D&I by building diverse, inclusive work teamsfor the sales value we expect. If the ultimate sales value of our interest in these projects is lower than expected, or we are unable to sell our interests, it could have an adverse effect on our financial condition and results of operations. The sales agreements are subject to certain regulatory approvals as well as other conditions, and we may be unable to satisfy all closing conditions necessary to consummate the purchase and sale transactions. The purchaser of the Revolution Wind and South Fork Wind projects may be unable to reach a partnership agreement with high engagement, growingØrsted, which is a pipelinecondition of diverse talent, leveraging multiple perspectivesclosing that transaction. The sale of the Sunrise Wind project to improve customer service, using diverse suppliers, engaging with multicultural organizationsØrsted is dependent on the successful outcome of Sunrise Wind’s re-bidding process of its OREC contract in the New York solicitation. If Sunrise Wind were to lose to a competing bid in the New York solicitation, then the existing OREC contract for Sunrise Wind will be cancelled according to the state’s requirements, and Eversource and Ørsted’s joint venture for Sunrise Wind will remain in place. That scenario could adversely impact the ability to sell the Sunrise Wind project in the future, and could result in the project to be abandoned. If the Sunrise Wind project were to be abandoned, there would be cancellation and other abandonment costs incurred, and those costs could be above amounts already assumed in our communitiesimpairment evaluation and supportingreflected in the workcurrent fair value on our balance sheet, which could have an adverse effect on our financial condition and results of the D&I council and business resource groups.

Eversource's BoardFuture cash flows resulting from the expected sales are also impacted by the ability to qualify the Revolution Wind project for investment tax credit adders, as included in the Inflation Reduction Act. Evaluating the project’s qualifications to achieve these investment tax credit adders requires significant judgment, and we may be unable to meet these qualifications. Additionally, for Revolution Wind and South Fork Wind, there could be cost overruns on the projects through each project's respective commercial operation date, which would not be recovered in the expected sales price and other potential future payments to maintain transaction economics required of Trustees is committed to diversityEversource.

Regulatory, Legislative and Compliance Risks:

The actions of regulators and legislators could result in outcomes that may adversely affect our earnings and liquidity.

Compensation, HealthThe rates that our electric, natural gas and Wellness Benefitswater companies charge their customers are determined by their state regulatory commissions. We are committed to These commissions also regulate the health, safetycompanies' accounting, operations, the issuance of certain securities and wellnesscertain other matters.

Our electric, natural gas and water companies are required to engage in regulatory approval proceedings as a part of the process of establishing the terms and rates for their respective services. Each of these companies prepares and submits periodic rate filings with their respective state regulatory commissions for review and approval, which allows for various entities to challenge our current or future rates, structures or mechanisms and could alter or limit the rates we are allowed to charge our customers. These proceedings typically involve multiple parties, including governmental bodies and officials, consumer advocacy groups, and various consumers of energy, who have differing concerns. Any change in rates, including changes in allowed rate of return, are subject to regulatory approval proceedings that buildcan be contentious, lengthy, and strengthen employees’ leadership and skill set.

The FERC also has jurisdiction over our transmission rate incentives such as the environment,regional transmission organization (RTO) participation ROE incentive adder, CWIP in rate base incentive and initiativesthe abandoned plant incentive. If the FERC changes its policies regarding these incentives, there could be a negative impact on our financial position, results of operations and cash flows. Additionally, the FERC issued a Supplemental Notice of Proposed Rulemaking (NOPR) on Transmission Incentives that address local, high-priority concernsproposes to eliminate the existing RTO ROE incentive adder for utilities that have been participating in an RTO for more than three years.

Implementation of FERC's goals, including significant volunteer hourswithin our service territories, may expose us to competition for construction of transmission projects, additional regulatory considerations, and potential delay with respect to future transmission projects, which may adversely affect our employees.results of operations and lower rate base growth.

SeeChanges in tax laws, as well as the potential tax effects of business decisions could negatively impact our business, results of operations, financial condition and cash flows.

We are exposed to significant reputational risks, which make us vulnerable to increased regulatory oversight or other sanctions.

Because utility companies, including our electric, natural gas and water utility subsidiaries, have large customer bases, they are subject to adverse publicity focused on the reliability of their distribution services and the speed with which they are able to respond to electric outages, natural gas leaks and similar interruptions caused by storm damage or other unanticipated events, including those related to climate change. Adverse publicity of this nature could harm our reputation and the reputation of our subsidiaries; may make state legislatures, utility commissions and other regulatory authorities less likely to view us in a favorable light; and may cause us to be subject to less favorable legislative and regulatory outcomes, legal claims or increased regulatory oversight. Unfavorable regulatory outcomes can include more stringent laws and regulations governing our operations, such as reliability and customer service quality standards or vegetation management requirements, as well as fines, penalties or other sanctions or requirements. Further, we rely upon purchased power and purchased natural gas supply from third parties to meet customers’ energy requirements.Due to a variety of factors, including the inflationary economic environment, geo-political conflicts, and increased customer energy demand, the cost of energy supply in New England remains high. We also may be required to implement rolling blackouts by ISO-NE, the region’s independent grid operator if enough capacity is not available in the area to meet peak demand needs. The significant supply cost increases, as well as any failure to meet customer energy requirements, could negatively impact the satisfaction of our customers and our customers’ ability to pay their utility bills, which could have an adverse impact on our business, reputation, financial position, results of operations and cash flows.

Addressing any adverse publicity, regulatory scrutiny or enforcement or other legal proceedings is time consuming and expensive and, regardless of the factual basis for the assertions being made, can have a negative impact on the reputation of our business, on the morale and performance of our employees and on our relationships with respective regulators, customers and counterparties. We are unable to predict future legislative or regulatory changes, initiatives or interpretations or other legal proceedings, and there can be no assurance that we will be able to respond adequately to such actions. The direct and indirect effects of negative publicity, and the demands of responding to and addressing it, may have a material adverse effect on our financial position, results of operations and cash flows.

Costs of compliance with environmental laws and regulations, including those related to climate change, may increase and have an adverse effect on our business and results of operations.

Our subsidiaries’ operations are subject to extensive and increasing federal, state and local environmental statutes, rules and regulations that govern, among other things, water quality (including treatment of PFAS (Per- and Polyfluoroalkyl Substances) and lead), water discharges, the management of hazardous material and solid waste, and air emissions. Compliance with these requirements requires us to incur significant costs relating to environmental permitting, monitoring, maintenance and upgrading of facilities, remediation, and reporting. For our water business, compliance with proposed water quality regulations, including those for PFAS and lead, could require the construction of facilities and replacement of customer lead service lines, respectively.

18


The costs of compliance with existing legal requirements or legal requirements not yet adopted may increase in the future. Although we have recorded liabilities for known environmental obligations, these costs can be difficult to estimate due to uncertainties about the extent of contamination, remediation alternatives, the remediation levels required by state and federal agencies, and the financial ability of other potentially responsible parties. An increase in such costs, unless promptly recovered, could have an adverse impact on our business and our financial position, results of operations and cash flows.

For further information, see Item 11, 1,Executive CompensationBusinessOther Regulatory and Environmental Matters, included in this Annual Report on Form 10-K,10-K.

Risks Related to the Environment and Catastrophic Events:

The effects of climate change, including severe storms, could cause significant damage to any of our facilities requiring extensive expenditures, the recovery for which is subject to approval by regulators.

Climate change creates physical and financial risks to our operations. Physical risks from climate change may include an increase in sea levels and changes in weather conditions, such as changes in precipitation, extreme heat and extreme weather events. Customers’ energy and water needs vary with weather conditions, primarily temperature and humidity. For residential customers, heating and cooling represent their largest energy use. For water customers, conservation measures imposed by the communities we serve could impact water usage. To the extent weather conditions are affected by climate change, customers’ energy and water usage could increase or decrease depending on the duration and magnitude of the changes.

Severe weather induced by climate change, such as extreme and frequent ice and snow storms, tornadoes, micro-bursts, hurricanes, floods, droughts, wildfires, and other natural disasters, may cause outages and property damage, which may require us to incur additional costs that may not be recoverable from customers. The cost of repairing damage to our operating subsidiaries' facilities and the potential disruption of their operations due to storms, natural disasters or other catastrophic events could be substantial, particularly as regulators and customers demand better and quicker response times to outages. If, upon review, any of our state regulatory authorities finds that our actions were imprudent, some of those restoration costs may not be recoverable from customers and could result in penalties or fines. The inability to recover a significant amount of such costs could have an adverse effect on our financial position, results of operations and cash flows. We maintain property insurance, but it may be insufficient in limits and coverage exclusions to cover all losses. Additionally, these types of weather events risk interruption of the supply chain and could disrupt the delivery of goods and services required for our operations.

Transitional impacts related to climate change may have an adverse effect on our business and results of operations due to costs associated with new technologies, evolving customer expectations and changing workforce needs.

Initiatives to mitigate the impacts of climate change, support a transition to cleaner energy, and reduce emissions, may have a material adverse financial impact to our business. These impacts include the costs associated with the development and implementation of new technologies to maintain system reliability and resiliency and lower emissions, including grid modernization and energy storage. An increase in such costs, unless promptly recovered, could have an adverse impact on our financial position, results of operations and cash flows. There may also be financial and reputational risks if we fail to meet evolving customer expectations, including enabling the integration of residential renewables and providing low carbon solutions, such as electric vehicle infrastructure and energy efficiency services. Additionally, actions to mitigate climate change may result in a transition in our workforce that must adapt to meet the need for new job skills. Associated costs include training programs for existing employees and workforce development as we transition to new technologies and clean energy solutions.

Adequacy of water supplies and contamination of our water supplies, the failure of dams on reservoirs providing water to our customers, or requirements to repair, upgrade or dismantle any of these dams, may disrupt our ability to distribute water to our customers and result in substantial additional costs, which could adversely affect our financial position, results of operations and cash flows.

Our water business faces an inherent strategic risk related to adequacy of supply (i.e., water scarcity). Water scarcity risk is heightened by multiple factors. We expect that climate change will cause both an increase in demand due to increasing temperatures and a potential for a decrease of available supply due to shifting rainfall and recharge patterns. Regulatory constraints also present challenges to permit new sources of supply in the region. In Connecticut, where the vast majority of our dams are located, impounded waterways are required to release minimum downstream flow. New regulations are being phased into effect over the next one to five years that will increase the volume of downstream releases required across our Connecticut service territory, depleting the volume of supply in storage that is used to meet customer demands. This combination of factors may cause an increased likelihood of drought emergencies and water use restrictions that could adversely affect our ability to provide water to our customers, and reputational/brand damage that could negatively impact our water business.

Our water supplies, including water provided to our customers, are also subject to possible contamination from naturally occurring compounds and elements or non-organic substances, including PFAS and lead. Our water systems include impounding dams and reservoirs of various sizes. Although we believe our dams are structurally sound and well-maintained, significant damage to these facilities, or a significant decrease in the water in our reservoirs, could adversely affect our ability to provide water to our customers until the facilities and a sufficient amount of water in our reservoirs can be restored. A failure of a dam could result in personal injuries and downstream property damage for which we may be liable. The failure of a dam would also adversely affect our ability to supply water in sufficient quantities to our customers. Any losses or liabilities incurred due to a failure of one of our dams may not be recoverable in rates and may have a material adverse effect on our financial position, results of operations and cash flows. We maintain liability insurance, but it may be insufficient in limits and coverage exclusions to cover all losses.

Physical attacks, including acts of war or terrorism, both threatened and actual, could adversely affect our ability to operate our systems and could adversely affect our financial results and liquidity.

Physical attacks, including acts of war or terrorism, both threatened and actual, that damage our transmission and distribution systems or other assets could negatively impact our ability to transmit or distribute energy, water, natural gas, or operate our systems efficiently or at all. Because our electric transmission systems are part of an interconnected regional grid, we face the risk of widespread blackouts due to grid disturbances or disruptions on a neighboring interconnected system. Similarly, our natural gas distribution system is connected to transmission pipelines not owned by Eversource. If there was an attack on the transmission pipelines, it could impact our ability to deliver natural gas. If our assets were physically damaged and were not recovered in a timely manner, it could result in a loss of service to customers, a significant decrease in revenues, significant expense to repair system damage, costs associated with governmental actions in response to such attacks, and liability claims, all of which could have a material adverse impact on our financial position, results of operations and cash flows. We maintain property and liability insurance, but it may be insufficient in limits and coverage exclusions to cover all losses. In addition, physical attacks against third-party providers could have a similar effect on the operation of our systems.

Business and Operational Risks:

Strategic development or investment opportunities in electric transmission, distributed generation, or clean-energy technologies may not be successful, which could have a material adverse effect on our business prospects.

We are pursuing investment opportunities in electric transmission facilities, distributed generation and other clean-energy infrastructure, including interconnection facilities. The development of these projects involve numerous significant risks including federal, state and local permitting and regulatory approval processes, scheduling or permitting delays, increased costs, tax strategies and changes to federal tax laws, new legislation impacting the industry, economic events or factors, environmental and community concerns, design and siting issues, difficulties in obtaining required rights of way, and competition from incumbent utilities and other entities. Also, supply constraints in New England have led to significant increases in commodity costs which may impact our ability to accomplish our strategic objectives. Further, regional clean energy goals may not be achieved if local, state, and federal policy is not in alignment with integrated planning of our infrastructure investments.

Our transmission and distribution systems may not operate as expected, and could require unplanned expenditures, which could adversely affect our financial position, results of operations and cash flows.

Our ability to properly operate our transmission and distribution systems is critical to the financial performance of our business. Our transmission and distribution businesses face several operational risks, including the breakdown, failure of, or damage to operating equipment, information technology systems, or processes, especially due to age; labor disputes; disruptions in the delivery of electricity, natural gas and water; increased capital expenditure requirements, including those due to environmental regulation; catastrophic events resulting from equipment failures such as wildfires and explosions, or external events such as a solar event, an electromagnetic event, or other similar occurrences; increasingly severe weather conditions due to climate change beyond equipment and plant design capacity; human error; global supply chain disruptions; and potential claims for property damage or personal injuries beyond the scope of our insurance coverage. Many of our transmission projects are expected to alleviate identified reliability issues and reduce customers' costs. However, if the in-service date for one or more of these projects is delayed due to economic events or factors, or regulatory or other delays, including permitting and siting, the risk of failures in the electric transmission system may increase. We also implement new information technology systems from time to time, which may disrupt operations. Any failure of our transmission and distribution systems to operate as planned may result in increased capital costs, reduced earnings or unplanned increases in operations and maintenance costs. The inability to recover a significant amount of such costs could have an adverse effect on our financial position, results of operations and cash flows.

New technology and alternative energy sources could adversely affect our operations and financial results.

Advances in technology that reduce the costs of alternative methods of producing electric energy to a level that is competitive with that of current electric production methods, could result in loss of market share and customers, and may require us to make significant expenditures to remain competitive. These changes in technology, including micro-grids and advances in energy or battery storage, could also alter the channels through which electric customers buy or utilize energy, which could reduce our revenues or increase our expenses. Economic downturns or periods of high energy supply costs typically can lead to the development of legislative and regulatory policy designed to promote reductions in energy consumption and increased energy efficiency and self-generation by customers. Additionally, in response to risks posed by climate change, we may need to make investments in our system including upgrades or retrofits to meet enhanced design criteria, which can incur additional costs over conventional solutions.

We rely on third-party suppliers for equipment, materials, and services and we outsource certain business functions to third-party suppliers and service providers, and substandard performance or inability to fulfill obligations by those third parties could harm our business, reputation and results of operations.

We outsource certain services to third parties in areas including information technology, transaction processing, human resources, payroll and payroll processing and certain operational areas. Outsourcing of services to third parties could expose us to substandard quality of service delivery or substandard deliverables, which may result in missed deadlines or other timeliness issues, non-compliance (including with applicable legal requirements and industry standards) or reputational harm, which could negatively impact our results of operations. Our contractual arrangements with these contractors typically include performance standards, progress payments, insurance requirements and security for performance. The global supply chain of goods and services remains volatile, and as a result, we are seeing delivery delays of certain goods, particularly certain types
20


of transformers. If significant difficulties in the global supply chain cycle or inflationary impacts were to worsen, they could adversely affect our results of operations, or adversely affect our ability to work with regulators, unions, customers or employees.

The loss of key personnel, the inability to hire and retain qualified employees, or the failure to maintain a positive relationship with our workforce could have an adverse effect on our business, financial position and results of operations.

Our operations depend on the continued efforts of our employees. Retaining key employees and maintaining the ability to attract new employees are important to both our operational and financial performance. We cannot guarantee that any member of our management or any key employee at the Eversource parent or subsidiary level will continue to serve in any capacity for any particular period of time. Our workforce in our subsidiaries includes many workers with highly specialized skills maintaining and servicing the electric, natural gas and water infrastructure that cannot be quickly replaced due to the technically complex work they perform. We have developed strategic workforce plans to identify key functions and proactively implement plans to assure a ready and qualified workforce, but we cannot predict the impact of these plans on our ability to hire and retain key employees. Labor disputes, work stoppages or an inability to negotiate future collective bargaining agreements on commercially reasonable terms, as well as the “Our People” sectionincreased competition for talent or the intentional misconduct of employees or contractors, may also have an adverse effect on our business, financial position and results of operations.

Financial, Economic, and Market Risks:

Limits on our access to, or increases in, the cost of capital may adversely impact our ability to execute our business plan.

We use short-term debt and the long-term capital markets as a significant source of liquidity and funding for capital requirements not obtained from our operating cash flow. If access to these sources of liquidity becomes constrained, our ability to implement our business strategy could be adversely affected. In addition, interest rates have increased and may continue to increase in the future. As a result, interest rates on future credit facilities and debt offerings could be higher than current levels, causing our financing costs to increase accordingly, which could adversely impact our financial position, results of operations and cash flows. A downgrade of our 2019 Sustainability Report locatedcredit ratings or events beyond our control, such as a disruption in global capital and credit markets, could increase our cost of borrowing and cost of capital or restrict our ability to access the capital markets and negatively affect our ability to maintain and to expand our businesses.

Market performance or changes in assumptions may require us to make significant contributions to our pension and other postretirement benefit plans.

We provide a defined benefit pension plan and other postretirement benefits for a substantial number of employees, former employees and retirees. Our future pension obligations, costs and liabilities are highly dependent on a variety of factors, many of which are beyond our website, for more detailed information regardingcontrol. These factors include estimated investment returns, interest rates, discount rates, health care cost trends, benefit changes, salary increases and the demographics of plan participants. If our human capital programsassumptions prove to be inaccurate, our future costs could increase significantly.In addition, various factors, including underperformance of plan investments and initiatives. Nothing onchanges in law or regulation, could increase the amount of contributions required to fund our website, includingpension plan in the future. Additional large funding requirements, when combined with the financing requirements of our Sustainability Report or sections thereof, shall be deemed incorporated by reference into this Annual Report.construction program, could impact the timing, amounts, and number of future financings and negatively affect our financial position, results of operations and cash flows.

Goodwill, investments in equity method investments, and long-lived assets if impaired and written down, could adversely affect our future operating results and total capitalization.

We have a significant amount of goodwill on our consolidated balance sheet, which, as of December 31, 2023, totaled $4.53 billion. The carrying value of goodwill represents the fair value of an acquired business in excess of the fair value of identifiable assets and liabilities as of the acquisition date. We test our goodwill balances for impairment on an annual basis or whenever events occur, or circumstances change that would indicate a potential for impairment. A determination that goodwill is deemed to be impaired would result in a non-cash charge that could materially adversely affect our financial position, results of operations and total capitalization.

We assess our investments (recorded as either long-lived assets or equity method investments) for impairment whenever events or circumstances indicate that the carrying amount of the investment may not be recoverable. To the extent the value of the investment becomes impaired, the impairment charge could have a material adverse effect on our financial condition and results of operations.

Our counterparties may not meet their obligations to us or may elect to exercise their termination rights, which could adversely affect our earnings.

We are exposed to the risk that counterparties to various arrangements that owe us money, have contracted to supply us with energy or other commodities or services, or that work with us as strategic partners, including on significant capital projects, will not be able to perform their obligations, will terminate such arrangements or, with respect to our credit facilities, fail to honor their commitments. Should any of these counterparties fail to perform their obligations or terminate such arrangements, we might be forced to replace the underlying commitment at higher market prices and/or have to delay the completion of, or cancel, a capital project. Should any lenders under our credit facilities fail to perform, the level of borrowing capacity under those arrangements could decrease. In any such events, our financial position, results of operations, or cash flows could be adversely affected.

As a holding company with no revenue-generating operations, Eversource parent's liquidity is dependent on dividends from its subsidiaries, its commercial paper program, and its ability to access the long-term debt and equity capital markets.

Eversource parent is a holding company and as such, has no revenue-generating operations of its own. Its ability to meet its debt service obligations and to pay dividends on its common shares is largely dependent on the ability of its subsidiaries to pay dividends to, or repay borrowings from, Eversource parent, and/or Eversource parent's ability to access its commercial paper program or the long-term debt and equity capital markets. Prior to funding Eversource parent, the subsidiary companies have financial obligations that must be satisfied, including among others, their operating expenses, debt service, preferred dividends of certain subsidiaries, and obligations to trade creditors. Should the subsidiary companies not be able to pay dividends or repay funds due to Eversource parent, or if Eversource parent cannot access its commercial paper programs or the long-term debt and equity capital markets, Eversource parent's ability to pay interest, dividends and its own debt obligations would be restricted.

Item 1B.    Unresolved Staff Comments

We do not have any unresolved SEC staff comments.

Item 1C. Cybersecurity

The Company’s policies, practices and technologies allow it to protect its information systems and operational assets from threats. The Board of Trustees and its Finance and Audit Committees continue to provide substantial and focused attention to cyber and system security. The Finance Committee of the Board of Trustees is responsible for oversight of the Company’s enterprise-wide risks, including risks associated with cyber and physical security, and the Company’s programs and practices to monitor and mitigate these risks.

Management prepares comprehensive cyber security reports that are discussed at each meeting of the Finance Committee. The reports focus on the changing threat landscape and the risks to the Company, describe Eversource’s cyber security drills and exercises, attempted and actual breaches on our systems, cyber incidents within the utility industry and around the world, and mitigation strategies. In addition, third-party experts of cyber security risks provide periodic assessments to the utility industry and the Company in particular to the Finance Committee. The Company regularly reviews and updates its cyber and system security programs, and the Finance Committee continues to enhance its robust oversight activities, including meetings with financial, information technology, legal and accounting management, other members of the Board, representatives of the Company’s independent registered public accounting firm, and outside advisors and experts in cyber security risks, at which cyber and system security programs and issues that might affect the Company’s financial statements and operational systems are discussed.

The Company has a robust Enterprise Risk Management Program which has identified cyber security as a top enterprise risk. The managing and monitoring of risks are the responsibility of the Company’s Risk Committee, which meets quarterly and is chaired by the Chief Financial Officer.

The Company is committed to continuous monitoring and assessment of cyber security controls. The Chief Information Security Officer is responsible for developing, implementing, and enforcing our cyber security program and information security policies to protect the Company’s information systems and operational assets. The Chief Information Security Officer position requires at least 15 years of relevant information security experience and relevant security certifications. The Chief Information Security Officer reports directly to the Chief Information Officer and provides regular updates to the executive management team. Our Chief Information Security Officer has over 20 years of relevant experience.

The Company created a Cyber Governance Committee, which includes the Chief Information Security Officer, Chief Information Technology Officer, Chief Accounting Officer, members of the executive management team, and other assurance functions such as Corporate Compliance, Enterprise Risk Management, and Internal Audit.

To assess, identify and manage material risks from cybersecurity threats and to prevent, detect, mitigate and remediate a cyber security or ransomware incident, the following key processes and programs have been implemented and are performed by the Company’s Cyber Security Group, which is overseen by the Chief Information Security Officer:

Implementation of security solutions and standards based on industry best practices to prevent unauthorized access. The Company’s cyber program has been modeled after the National Institute of Standards and Technology framework; a widely accepted framework utilized by critical infrastructure industries.
Periodic external assessments, including outside system access testing, are performed. Rigorous auditing of all safeguards is performed on a regular basis. Risk assessments are held to identify and address new and changing risks to protect systems and sensitive data. Identified areas are monitored and improvements are implemented.
Eversource participates in information sharing programs both within and outside the utility industry, including with the U.S. government and industry organizations, to be able to identify and respond to emerging threats.
The Company maintains current incident response and business continuity plans, which are periodically updated and tested.
Network activity is monitored on an ongoing basis.
Anti-phishing and malware tools are utilized and assessed.
Employees are trained to recognize phishing attempts and are periodically tested. Results of phishing testing are benchmarked against other companies both within and outside the utility industry.

22


Specific to third parties, Eversource has implemented formal screening processes for any applicable vendors by the Company’s Cyber Security Group as part of the Procurement process. The vendors are risk ranked based on the type of work being performed. Periodic rescreening is performed on critical vendors. Vendors are required to attest to their business continuity programs and provide evidence of appropriate insurance and indemnification agreements. The Company bars sourcing from countries included on the Department of Homeland Security’s list of Prohibited Nations to further protect the Company’s supply chain. The Company maintains cyber insurance which covers breaches of networks and operational technology. Our existing insurance limits may be inadequate to cover a material cyber incident. This could expose us to potentially significant claims and damages.

As of December 31, 2023, there were no risks from cybersecurity threats, including due to any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the Company, its business strategy, results of operations, or financial condition.

Item 1A. Risk Factors

In addition to the matters set forth under "Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995" included immediately prior to Item 1, Business, above, we are subject to a variety of material risks. Our susceptibility to certain risks, including those discussed in detail below, could exacerbate other risks. These risk factors should be considered carefully in evaluating our risk profile. There may be additional risks and uncertainties (either currently unknown or not currently believed to be material) that could adversely affect our financial position, results of operations, and cash flows.

Cybersecurity Threats and Data Privacy Risks:Attacks:

Cyberattacks, including acts of war or terrorism, targeted directly on or indirectly affecting our systems or the systems of third parties on which we rely, could severely impair operations, negatively impact our business, lead to the disclosure of confidential information and adversely affect our reputation.

Cyberattacks that seek to exploit potential vulnerabilities in the utility industry and seek to disrupt electric, natural gas and water transmission and distribution systems are increasing in sophistication, magnitude and frequency. Various geo-political conflicts and acts of war around the world continue to result in increased cyberattacks against critical infrastructure.A successful cyberattack on the information technology systems that control our transmission, distribution, natural gas and water systems or other assets could impair or prevent us from managing these systems and facilities, operating our systems effectively, or properly managing our data, networks and programs. The breach of certain information technology systems could adversely affect our ability to correctly record, process and report financial information. A major cyber incident could result in significant expenses to investigate and to repair system damage or security breaches and could lead to litigation, fines, other remedial action, heightened regulatory scrutiny and damage to our reputation.

We have instituted safeguards to protect our information technology systems and assets. We deployeddeploy substantial technologies to system and application security, encryption and other measures to protect our computer systems and infrastructure from unauthorized access or misuse. Specifically, regarding vulnerabilities, we patch systems where patches are available to deploy, and have technologies that detect exploits of vulnerabilities and proactively block the exploit when it happens. We also interface with numerous external entities to improve our cybersecurity situational awareness. The FERC, through the North American Electric Reliability Corporation (NERC), requires certain safeguards to be implemented to deter cyberattacks. These safeguards may not always be effective due to the evolving nature of cyberattacks. We maintain cyber insurance to cover damages, potential ransom and defense costs related to breaches of networks or operational technology, but it may be insufficient in limits and coverage exclusions to cover all losses.

Any such cyberattacks could result in loss of service to customers and a significant decrease in revenues, which could have a material adverse impact on our financial position, results of operations and cash flows.

For further information, see Item 1C, Cybersecurity included in this Annual Report on Form 10-K.

The unauthorized access to, and the misappropriation of, confidential and proprietary Company, customer, employee, financial or system operating information could adversely affect our business operations and adversely impact our reputation.

In the regular course of business, we, and our third-party suppliers, rely on information technology to maintain sensitive Company, customer, employee, financial and system operating information. We are required by various federal and state laws to safeguard this information. Cyber intrusions, security breaches, theft or loss of this information by cybercrime or otherwise could lead to the release of critical operating information or confidential Company, customer or employee information, which could adversely affect our business operations or adversely impact our reputation, and could result in significant costs, fines and litigation. We employ system controls to prevent the dissemination of certain confidential information and periodically train employees on phishing risks. We maintain cyber insurance to cover damages, potential ransom and defense costs arising from unauthorized disclosure of, or failure to protect, private information, as well as costs for notification to, or for credit monitoring of, customers, employees and other persons in the event of a breach of private information. This insurance covers amounts paid to avert, prevent or stopaddress a network attack or the disclosure of personal information, and costs of a qualified forensics firm to determine the cause, source and extent of a network attack or to investigate, examine and analyze our network to find the cause, source and extent of a data breach, but it may be insufficient to cover all losses. While we have implemented measures designed to prevent network attacks and mitigate their effects should they occur, these measures may not be effective due to the continually evolving nature of efforts to access confidential information.

Pandemic Risks, including COVID-19 Related Risks:Offshore Wind Business Risk:

As evidenced byOur financial position and future results could be materially adversely affected if we are unable to sell our 50 percent interests in three offshore wind projects on the global pandemictimelines, terms and pricing we expect, if we and the counterparties are unable to satisfy all closing conditions and consummate the purchase and sale transactions with respect to our offshore wind assets, if Sunrise Wind does not win in the OREC contract solicitation process, if we are unable to qualify for investment tax credits related to these projects, if we experience variability in the projected construction costs of the 2019 novel coronavirus (COVID-19), global pandemics result in widespread disruption to the overall economicoffshore wind projects, if there is a deterioration of market and outlook, which could cause various unfavorable impacts to our customers, vendors, employees, regulators, and operations and could adversely affect our financial position, results of operations and cash flows.

We continue to respond to COVID-19 by taking steps to mitigate the potential risks to Eversource posed by its spread. We provide a critical service to our customers, which means it is paramount that we keep our employees who operate our businesses safe, and minimize unnecessary risk of exposure to COVID-19. We have updated and implemented our company-wide pandemic plan to address specific aspects of the COVID-19 pandemic. This plan guides our emergency response, business continuity, and the precautionary measures we are taking on behalf of employees and our customers.

Cybersecurity attacks: We, as well as othersconditions in the poweroffshore wind industry, and utility industry, have continued to experience significant events where outside parties, utilizing sophisticated methods, have attempted to compromise both our vendors and employees to try to gain access to our email systems,if the projects do not commence operation as well as attempting to access our other systemsscheduled or networks. Eversource waswithin budget or are not affected by the SolarWinds event. We continue to implement strong cybersecurity measures and have increased the education of our employees and contractors to ensure that our systems remain functional in order to both serve our operational needs with a remote workforce and to ensure uninterrupted service to our customers. Our incident response team works with compromised vendors to assist them in improving their security posture. We also continuously review and update our response plans to include responding to an event while in a remote work environment.completed.

Access to, or cost of, capital resources: We utilize the commercial paper market extensively for our short-term borrowing needs. At the onset of the pandemicOur offshore wind business includes 50 percent ownership interests in the United States, liquidity in the commercial paper credit market began to deteriorate rapidly. However, federal legislative actions, including actions taken by the Federal Reserve, have provided sufficient liquidity and stabilization of the credit markets. We continue to monitor the ability for us to access the global capital and credit markets; however, if we are unable to access these markets, then our financial condition may be adversely affected. We have had open, full access to the capital markets throughout the COVID-19 pandemic.

Actions of regulators: We continue to work closely with our state regulatory commissions and consumer advocates on customer assistance measures, including payment plan options in order to mitigate the impact on customer rates in the future, as well as financial hardship and arrearage management programs for those customers who are unable to pay their utility bills. We developed these long-term solutions for customers in order to help minimize the extent of the impact of COVID-19 on customer receivable balances and customers’ affordability in light of the current financial impact they may experience. We believe that we have in place, or are developing, successful mechanisms with our state regulatory commissions to recover our incremental costs associated with COVID-19, while balancing the impact on our customers’ bills and our operating cash flows, however our financial condition may be adversely affected depending on the outcome of planned proceedings before our state regulatory commissions.

Timing of strategic development opportunities: The successful execution of our timeline for developing ourthree jointly-owned offshore wind projects is based on several factors, including statebeing developed and federal sitingconstructed. The development and permitting approvals. We implemented,and continue to update, mitigation plans that addressed permitting delays due to COVID-19 work restrictions between March and June 2020 that resulted in a moderate impact to our offshore wind projects siting and permit filing timelines. However, we are unable to assess the potential impact that a reintroductionconstruction of work restrictions in response to a future resurgence in COVID-19 infections would have on our projects’ timelines.

Suppliers and Vendors: We have instituted measures to ensure our supply chain remains open to us; however, there could be global shortages that will impact our maintenance, capital programs, and storm response that we currently cannot anticipate.

Loss of key personnel: We continue to adjust our pandemic plan to address various scenarios including reduced workforce levels and limited mutual aid in the event of a significant storm event. We have implemented remote work arrangements for our workforce by enabling nearly half of our employees to work from home and taking extra precautions for our field-based employees. We have taken significant safety measures to ensure adequate social distancing for our field crews to safely provide essential services to our customers. We have also adopted protocols to ensure the safety and health of those employees who work onsite in critical facilities. We continue to monitor COVID-19 developments affecting our workforce and will take additional precautions that we determine are necessary in order to mitigate the impacts. Although to date our workforce continues to be able to safely and reliably deliver our critical services to customers, we are unable to predict the extent of the impact of COVID-19 on our employees.

The extent of the impact to us in the future will vary and depend in large part on the duration, scope and severity of the pandemic and the timing and extent of COVID-19 relief legislation, and the resulting impact on economic, health care and capital market conditions. The future impact will also depend on the outcome of planned proceedings before our state regulatory commissions to recover our incremental costs associated with COVID-19, which include uncollectible customer receivable expenses. As a result, we are currently unable to estimate the potential impact of COVID-19 to our financial position, results of operations and cash flows.

Business Risks:

Strategic development opportunities associated with offshore wind or investment opportunities in electric transmission or clean-energy opportunities may not be successful, and projects may not commence operation as scheduled or be completed, which could have a material adverse effect on our business prospects.

We are pursuing broader strategic development investment opportunities that will benefit the Northeast region related to the construction ofthese offshore wind electric generation facilities and investment opportunities in electric transmission facilities and other clean-energy infrastructure. The development of these activities involves numerous significant risks around schedule, cost, capacity factors, tax strategies and permitting (both on and offshore). Various external factors could result in increased costs or result in delays or cancellation of these projects. Risks includeincluding meeting construction schedules, federal, state and local permitting and regulatory approval processes, scheduling or permitting delays, cost overruns, higher interest rates, tax strategies and changes to federal tax laws impacting the offshore wind partnership’s ability to monetize tax attributes, new legislation impacting the industry, changes to federal income tax laws, economic events or factors, environmental and community concerns, design and siting issues, difficulties in obtaining required rightsthe cancellation of way, competition from incumbent utilities and other entities,any projects, and actions of our strategic partners. Should anypartner. Operational risks of these factors result in significant delays or cancellations, our financial position, results of operations, and cash flows could be materially adversely affected, or our future growth opportunities may not be realized as anticipated.

Eversource has a joint and equal partnership with Ørsted for the development and operation of three offshore wind projects. Offshore wind is currently an emerging industry in the U.S., but it has a very robust operational and construction history in Europe. As such, siting, permitting, tax legislation, and supply chain are currently being addressed for the first time in the U.S. The projects currently being developed by our partnership may not achieve the results we anticipate. The partnership’s ability to generate revenue from offshore wind projects depends on meeting our construction schedules, controlling cost overruns,electric generation facilities include maintaining continuing interconnection arrangements, power purchase agreements, or other market mechanisms, as well as interconnecting utility and Regional Transmission Organizations rules, policies, procedures and FERC tariffs that permit future offshore wind project operations. Afteroperations, and capacity factors once projects are placed in operation, capacity factors will directly affect revenues generated from these investments. Other factors that may have an adverseoperation. These risks could impact on our anticipated project returns include significant schedule delays resulting from federal, state or local permitting processes. Specifically, the approval from the BOEM is a critical path item in the projects' timeline. Any changes to tax laws or to Eversource’soffshore wind partnership’s ability to monetize tax attributes associated with thesegenerate returns from its offshore wind projects could also have a material adverse effect on cash flows and projectresult in lower investment returns.

As a result of legislative and regulatory changes,We have entered into agreements to sell our interest in the states in which we provide service have implemented new selection procedures for new major electric transmission,three offshore wind projects, however we may be unable to complete the sales of these projects on the timelines and other clean energy facilities. These procedures requirefor the review of competing projects and permit the selection of only those projects that are expected to provide the greatest benefit to customers.sales value we expect. If the ultimate sales value of our interest in these projects in whichis lower than expected, or we have invested are not selected for construction, or even ifunable to sell our projects are selected, then legislative or regulatory actions could result in our projects not being probable of entering the construction phase, whichinterests, it could have a materialan adverse effect on our financial condition and results of operations. The sales agreements are subject to certain regulatory approvals as well as other conditions, and we may be unable to satisfy all closing conditions necessary to consummate the purchase and sale transactions. The purchaser of the Revolution Wind and South Fork Wind projects may be unable to reach a partnership agreement with Ørsted, which is a condition of closing that transaction. The sale of the Sunrise Wind project to Ørsted is dependent on the successful outcome of Sunrise Wind’s re-bidding process of its OREC contract in the New York solicitation. If Sunrise Wind were to lose to a competing bid in the New York solicitation, then the existing OREC contract for Sunrise Wind will be cancelled according to the state’s requirements, and Eversource and Ørsted’s joint venture for Sunrise Wind will remain in place. That scenario could adversely impact the ability to sell the Sunrise Wind project in the future, and could result in the project to be abandoned. If the Sunrise Wind project were to be abandoned, there would be cancellation and other abandonment costs incurred, and those costs could be above amounts already assumed in our impairment evaluation and reflected in the current fair value on our balance sheet, which could have an adverse effect on our financial condition and results of operations.

Future cash flows resulting from the expected sales are also impacted by the ability to qualify the Revolution Wind project for investment tax credit adders, as included in the Inflation Reduction Act. Evaluating the project’s qualifications to achieve these investment tax credit adders requires significant judgment, and we may be unable to meet these qualifications. Additionally, for Revolution Wind and South Fork Wind, there could be cost overruns on the projects through each project's respective commercial operation date, which would not be recovered in the expected sales price and other potential future payments to maintain transaction economics required of Eversource. Amounts incurred above those that have already been assumed in our impairment evaluation and reflected in the current fair value on our balance sheet would adversely impact our financial position, results of operations and cash flows.

We outsource certain business functions to third-party suppliersThese risks could adversely affect the ultimate value of the wind projects and service providers, and substandard performance by those third partiesresult in an additional, significant impairment in a future period, which could harmhave a material adverse effect on our business, reputationfinancial condition and results of operations. Lower-than-expected sales prices, or the inability to sell the wind projects, could also result in liquidity issues, negatively impact certain of our financial metrics and operations plan, or could result in a downgrade in our credit rating, which could increase our cost of borrowing and cost of capital or restrict our ability to access the capital markets.

We outsource certain services to third parties in areas including information technology, transaction processing, human resources, payrollRegulatory, Legislative and payroll processingCompliance Risks:

The actions of regulators and certain operational areas. As a result of our acquisition of the Columbia Gas of Massachusetts (CMA) assets from NiSource on October 9, 2020, we have entered into a Transition Services Agreement with NiSource whereby NiSource is performing certain services on behalf of our newly formed Eversource Gas Company of Massachusetts in the areas of information technology, transaction processing, human resources, payroll and payroll processing and certain operational areas for periods ranging from 1 to 24 months. Outsourcing of services to third partieslegislators could expose us to substandard quality of service delivery or substandard deliverables, which may result in missed deadlines or other timeliness issues, non-compliance (including with applicable legal requirements and industry standards) or reputational harm, which could negatively impact our results of operations. We also continue to pursue enhancements to standardize our systems and processes. If any difficulties in the operation of these systems were to occur, they couldoutcomes that may adversely affect our resultsearnings and liquidity.

The rates that our electric, natural gas and water companies charge their customers are determined by their state regulatory commissions. These commissions also regulate the companies' accounting, operations, the issuance of operations,certain securities and certain other matters. The FERC regulates the transmission of electric energy, the sale of electric energy at wholesale, accounting, issuance of certain securities and certain other matters, including reliability standards through the NERC. The regulatory process may be adversely affected by the political, regulatory and economic environment in the states in which we operate.

Under state and federal law, our electric, natural gas and water companies are entitled to charge rates that are sufficient to allow them an opportunity to recover their prudently incurred operating and capital costs and a reasonable rate of return on invested capital, to attract needed capital and maintain their financial integrity, while also protecting relevant public interests. Our electric, natural gas and water companies are required to engage in regulatory approval proceedings as a part of the process of establishing the terms and rates for their respective services. Each of these companies prepares and submits periodic rate filings with their respective state regulatory commissions for review and approval, which allows for various entities to challenge our current or adversely affectfuture rates, structures or mechanisms and could alter or limit the rates we are allowed to charge our customers. These proceedings typically involve multiple parties, including governmental bodies and officials, consumer advocacy groups, and various consumers of energy, who have differing concerns. Any change in rates, including changes in allowed rate of return, are subject to regulatory approval proceedings that can be contentious, lengthy, and subject to appeal. This may lead to uncertainty as to the ultimate result of those proceedings. Established rates are also subject to subsequent prudency reviews by state regulators, whereby various portions of rates could be adjusted, subject to refund or disallowed, including cost recovery mechanisms. The ultimate outcome and timing of regulatory rate proceedings, or challenges to certain provisions in our distribution tariffs could have a significant effect on our ability to work with regulators, unions, customersrecover costs or employees.

Our transmission and distribution systems may not operate as expected, and could require unplanned expenditures, whichearn an adequate return. Adverse decisions in our proceedings could adversely affect our financial position, results of operations and cash flows. We continue to experience challenges related to the regulatory environment in Connecticut with respect to our electric distribution, natural gas, and water businesses.

Our ability to properly operate our transmission
17


The federal, state and distribution systems is critical to the financial performance of our business. Our transmissionlocal political and distribution businesses face several operational risks, including the breakdown, failure of, or damage to operating equipment, information technology systems, or processes, especially due to age; labor disputes; disruptionseconomic environment currently has, and may in the deliveryfuture have, an adverse effect on regulatory decisions with negative consequences for us. These decisions may require us to cancel, reduce, or delay planned development activities or other planned capital expenditures or investments or otherwise incur costs that we may not be able to recover through rates. There can be no assurance that regulators will approve the recovery of electricity,all costs incurred by our electric, natural gas and water; increased capital expenditure requirements,water companies, including those due to environmental regulation; catastrophic events such as fires, explosions, a solar event, an electromagnetic event, or other similar occurrences; extreme weather conditions beyond equipment and plant design capacity; human error; and potential claimscosts for property damage or personal injuries beyond the scope of our insurance coverage. Many of our transmission projects are expected to alleviate identified reliability issues and reduce customers' costs. However, if the in-service date for one or more of these projects is delayed due to economic events or factors, or regulatory or other delays, the risk of failures in the electric transmission system may increase. Any failure of our transmission and distribution systems to operate as planned may result in increased capital costs, reduced earnings or unplanned increases inconstruction, operation and maintenance, costs.and storm restoration. The inability to recover a significant amount of suchoperating costs could have an adverse effect on our financial position, results of operations, and cash flows. Changes to rates may occur at times different from when costs are incurred. Additionally, catastrophic events at other utilities could result in our regulators and legislators imposing additional requirements that may lead to additional costs for the companies. In addition to the risk of disallowance of incurred costs, regulators may also impose downward adjustments in a company’s allowed ROE as well as assess penalties and fines. These actions would have an adverse effect on our financial position, results of operations and cash flows.

New technologyThe FERC has jurisdiction over our transmission costs recovery and alternative energy sourcesour allowed ROEs. If FERC changes its methodology on developing ROEs, there could be a negative impact on our results of operations and cash flows. Additionally, certain outside parties have filed four complaints against transmission-owning electric companies within ISO-NE alleging that our allowed ROEs are unjust and unreasonable. An adverse decision in any of these four complaints could adversely affect our financial position, results of operations and financial results.

cash flows.
Advances in technology that reduce the costs of alternative methods of producing electric energy to a level that is competitive with that of current electric production methods, could result in loss of market share and customers, and may require us to make significant expenditures to remain competitive. These changes in technology could also alter the channels through which electric customers buy or utilize energy, which could reduce our revenues or increase our expenses. Economic downturns or periods of high energy supply costs typically can lead to the development of legislative and regulatory policy designed to promote reductions in energy consumption and increased energy efficiency and self-generation by customers.

The lossFERC also has jurisdiction over our transmission rate incentives such as the regional transmission organization (RTO) participation ROE incentive adder, CWIP in rate base incentive and the abandoned plant incentive. If the FERC changes its policies regarding these incentives, there could be a negative impact on our financial position, results of key personnel,operations and cash flows. Additionally, the inabilityFERC issued a Supplemental Notice of Proposed Rulemaking (NOPR) on Transmission Incentives that proposes to hireeliminate the existing RTO ROE incentive adder for utilities that have been participating in an RTO for more than three years. A FERC decision approving this proposal could adversely affect our financial position, results of operations and retain qualified employees,cash flows.

FERC's policy has encouraged competition for transmission projects, even within existing service territories of electric companies, as it looks to expand the transmission system to accommodate state and federal policy goals to utilize more renewable energy resources as well as to enhance reliability and resilience for extreme weather events. Implementation of FERC's goals, including within our service territories, may expose us to competition for construction of transmission projects, additional regulatory considerations, and potential delay with respect to future transmission projects, which may adversely affect our results of operations and lower rate base growth.

Changes in tax laws, as well as the potential tax effects of business decisions could negatively impact our business, results of operations, financial condition and cash flows.

We are exposed to significant reputational risks, which make us vulnerable to increased regulatory oversight or other sanctions.

Because utility companies, including our electric, natural gas and water utility subsidiaries, have large customer bases, they are subject to adverse publicity focused on the reliability of their distribution services and the speed with which they are able to respond to electric outages, natural gas leaks and similar interruptions caused by storm damage or other unanticipated events, including those related to climate change. Adverse publicity of this nature could harm our reputation and the reputation of our subsidiaries; may make state legislatures, utility commissions and other regulatory authorities less likely to view us in a favorable light; and may cause us to be subject to less favorable legislative and regulatory outcomes, legal claims or increased regulatory oversight. Unfavorable regulatory outcomes can include more stringent laws and regulations governing our operations, such as reliability and customer service quality standards or vegetation management requirements, as well as fines, penalties or other sanctions or requirements. Further, we rely upon purchased power and purchased natural gas supply from third parties to meet customers’ energy requirements.Due to a variety of factors, including the inflationary economic environment, geo-political conflicts, and increased customer energy demand, the cost of energy supply in New England remains high. We also may be required to implement rolling blackouts by ISO-NE, the region’s independent grid operator if enough capacity is not available in the area to meet peak demand needs. The significant supply cost increases, as well as any failure to maintainmeet customer energy requirements, could negatively impact the satisfaction of our customers and our customers’ ability to pay their utility bills, which could have an adverse impact on our business, reputation, financial position, results of operations and cash flows.

Addressing any adverse publicity, regulatory scrutiny or enforcement or other legal proceedings is time consuming and expensive and, regardless of the factual basis for the assertions being made, can have a positive relationshipnegative impact on the reputation of our business, on the morale and performance of our employees and on our relationships with respective regulators, customers and counterparties. We are unable to predict future legislative or regulatory changes, initiatives or interpretations or other legal proceedings, and there can be no assurance that we will be able to respond adequately to such actions. The direct and indirect effects of negative publicity, and the demands of responding to and addressing it, may have a material adverse effect on our workforce couldfinancial position, results of operations and cash flows.

Costs of compliance with environmental laws and regulations, including those related to climate change, may increase and have an adverse effect on our business financial position and results of operations.

Our subsidiaries’operations depend onare subject to extensive and increasing federal, state and local environmental statutes, rules and regulations that govern, among other things, water quality (including treatment of PFAS (Per- and Polyfluoroalkyl Substances) and lead), water discharges, the continued effortsmanagement of hazardous material and solid waste, and air emissions. Compliance with these requirements requires us to incur significant costs relating to environmental permitting, monitoring, maintenance and upgrading of facilities, remediation, and reporting. For our employees. Retaining key employeeswater business, compliance with proposed water quality regulations, including those for PFAS and maintaininglead, could require the abilityconstruction of facilities and replacement of customer lead service lines, respectively.

The costs of compliance with existing legal requirements or legal requirements not yet adopted may increase in the future. Although we have recorded liabilities for known environmental obligations, these costs can be difficult to attract new employees are important to both our operational and financial performance. We cannot guarantee that any member of our management or any key employee at the Eversource parent or subsidiary level will continue to serve in any capacity for any particular period of time. In addition, a significant portion of our workforce in our subsidiaries, including many workers with specialized skills maintaining and servicing the electric, natural gas and water infrastructure, will be eligible to retire over the next five to ten years. Such highly skilled individuals cannot be quickly replacedestimate due to uncertainties about the technically complex work they perform. We have developed strategic workforce plans to identify key functionsextent of contamination, remediation alternatives, the remediation levels required by state and proactively implement plans to assure a readyfederal agencies, and qualified workforce, but we cannot predict the impactfinancial ability of these plans on our ability to hire and retain key employees. Labor disputes, work stoppages or an inability to negotiate future collective bargaining agreements on commercially reasonable terms, as well as the intentional misconduct of employees or contractors, may alsoother potentially responsible parties. An increase in such costs, unless promptly recovered, could have an adverse effectimpact on our business and our financial position, and results of operations.operations and cash flows.

For further information, see Item 1,BusinessOther Regulatory and Environmental Matters, included in this Annual Report on Form 10-K.

Risks Related to the Environment and Catastrophic Events:

The effects of climate change, including severe storms, could cause significant damage to any of our facilities requiring extensive expenditures, the recovery for which is subject to approval by regulators.

Climate change creates physical and financial risks to our operations. Physical risks from climate change may include an increase in sea levels and changes in weather conditions, such as changes in precipitation, extreme heat and extreme weather events including drought.events. Customers’ energy and water needs vary with weather conditions, primarily temperature and humidity. For residential customers, heating and cooling represent their largest energy use. For water customers, conservation measures imposed by the communities we serve could impact water usage. To the extent weather conditions are affected by climate change, customers’ energy and water usage could increase or decrease depending on the duration and magnitude of the changes.
18



Severe weather induced by climate change, such as extreme and frequent ice and snow storms, tornadoes, micro-bursts, hurricanes, floods, droughts, wildfires, and other natural disasters, may cause outages and property damage, which may require us to incur additional costs that may not be recoverable from customers. The cost of repairing damage to our operating subsidiaries' facilities and the potential disruption of their operations due to storms, natural disasters or other catastrophic events could be substantial, particularly as regulators and customers demand better and quicker response times to outages. If, upon review, any of our state regulatory authorities finds that our actions were imprudent, some of those restoration costs may not be recoverable from customers.customers and could result in penalties or fines. The inability to recover a significant amount of such costs could have an adverse effect on our financial position, results of operations and cash flows. We maintain property insurance, but it may be insufficient in limits and coverage exclusions to cover all losses. Additionally, these types of weather events risk interruption of the supply chain and could disrupt the delivery of goods and services required for our operations.

ContaminationTransitional impacts related to climate change may have an adverse effect on our business and results of operations due to costs associated with new technologies, evolving customer expectations and changing workforce needs.

Initiatives to mitigate the impacts of climate change, support a transition to cleaner energy, and reduce emissions, may have a material adverse financial impact to our business. These impacts include the costs associated with the development and implementation of new technologies to maintain system reliability and resiliency and lower emissions, including grid modernization and energy storage. An increase in such costs, unless promptly recovered, could have an adverse impact on our financial position, results of operations and cash flows. There may also be financial and reputational risks if we fail to meet evolving customer expectations, including enabling the integration of residential renewables and providing low carbon solutions, such as electric vehicle infrastructure and energy efficiency services. Additionally, actions to mitigate climate change may result in a transition in our workforce that must adapt to meet the need for new job skills. Associated costs include training programs for existing employees and workforce development as we transition to new technologies and clean energy solutions.

Adequacy of water supplies and contamination of our water supplies, the failure of dams on reservoirs providing water to our customers, or requirements to repair, upgrade or dismantle any of these dams, may disrupt our ability to distribute water to our customers and result in substantial additional costs, which could adversely affect our financial position, results of operations and cash flows.

Our water business faces an inherent strategic risk related to adequacy of supply (i.e., water scarcity). Water scarcity risk is heightened by multiple factors. We expect that climate change will cause both an increase in demand due to increasing temperatures and a potential for a decrease of available supply due to shifting rainfall and recharge patterns. Regulatory constraints also present challenges to permit new sources of supply in the region. In Connecticut, where the vast majority of our dams are located, impounded waterways are required to release minimum downstream flow. New regulations are being phased into effect over the next one to five years that will increase the volume of downstream releases required across our Connecticut service territory, depleting the volume of supply in storage that is used to meet customer demands. This combination of factors may cause an increased likelihood of drought emergencies and water use restrictions that could adversely affect our ability to provide water to our customers, and reputational/brand damage that could negatively impact our water business.

Our water supplies, including water provided to our customers, are also subject to possible contamination from naturally occurring compounds and elements or man-made substances.

non-organic
substances, including PFAS and lead.Our water systems include impounding dams and reservoirs of various sizes. Although we believe our dams are structurally sound and well-maintained, significant damage to these facilities, or a significant decrease in the water in our reservoirs, could adversely affect our ability to provide water to our customers until the facilities and a sufficient amount of water in our reservoirs can be restored. A failure of a dam could result in personal injuries and downstream property damage for which we may be liable. The failure of a dam would also adversely affect our ability to supply water in sufficient quantities to our customers. Any losses or liabilities incurred due to a failure of one of our dams may not be recoverable in rates and may have a material adverse effect on our financial position, results of operations and cash flows. We maintain liability insurance, but it may be insufficient in limits and coverage exclusions to cover all losses.

19


Physical attacks, including acts of war or terrorism, both threatened and actual, could adversely affect our ability to operate our systems and could adversely affect our financial results and liquidity.

Physical attacks, including acts of war or terrorism, both threatened and actual, that damage our transmission and distribution systems or other assets could negatively impact our ability to transmit or distribute energy, water, natural gas, or operate our systems efficiently or at all. Because our electric transmission systems are part of an interconnected regional grid, we face the risk of widespread blackouts due to grid disturbances or disruptions on a neighboring interconnected system. Similarly, our natural gas distribution system is connected to transmission pipelines not owned by Eversource. If there was an attack on the transmission pipelines, it could impact our ability to deliver natural gas. If our assets were physically damaged and were not recovered in a timely manner, it could result in a loss of service to customers, a significant decrease in revenues, significant expense to repair system damage, costs associated with governmental actions in response to such attacks, and liability claims, all of which could have a material adverse impact on our financial position, results of operations and cash flows. We maintain property and liability insurance, but it may be insufficient in limits and coverage exclusions to cover all losses. In addition, physical attacks against third-party providers could have a similar effect on the operation of our systems.

Regulatory, LegislativeBusiness and ComplianceOperational Risks:

Strategic development or investment opportunities in electric transmission, distributed generation, or clean-energy technologies may not be successful, which could have a material adverse effect on our business prospects.

We are pursuing investment opportunities in electric transmission facilities, distributed generation and other clean-energy infrastructure, including interconnection facilities. The actionsdevelopment of regulatorsthese projects involve numerous significant risks including federal, state and legislators could significantlylocal permitting and regulatory approval processes, scheduling or permitting delays, increased costs, tax strategies and changes to federal tax laws, new legislation impacting the industry, economic events or factors, environmental and community concerns, design and siting issues, difficulties in obtaining required rights of way, and competition from incumbent utilities and other entities. Also, supply constraints in New England have led to significant increases in commodity costs which may impact our ability to recover costsaccomplish our strategic objectives. Further, regional clean energy goals may not be achieved if local, state, and federal policy is not in a timely manner and can affectalignment with integrated planning of our earnings and liquidity.infrastructure investments.

The rates that our electric, natural gasOur transmission and water companies charge their customers are determined by their state regulatory commissions and by the FERC. These commissions also regulate the companies' accounting, operations, the issuance of certain securities and certain other matters. The FERC also regulates the transmission of electric energy, the sale of electric energy at wholesale, accounting, issuance of certain securities and certain other matters, including reliability standards through NERC.

Under state and federal law, our electric, natural gas and water companies are entitled to charge rates that are sufficient to allow them an opportunity to recover their prudently incurred operating and capital costs and a reasonable rate of return on invested capital, to attract needed capital and maintain their financial integrity, while also protecting relevant public interests. Each of these companies prepares and submits periodic rate filings with their respective regulatory commissions for review and approval, which allows for various entities to challenge our current or future rates, structures or mechanismsdistribution systems may not operate as expected, and could alter or limit the rates we are allowed to charge our customers and may not match the timing of when costs are incurred. Additionally, catastrophic events at other utilities could result in our regulators and legislators imposing additional requirements that may lead to additional costs for the Company.

There is no assurance that regulators will approve the recovery of all costs incurred by our electric, natural gas and water companies, including costs for construction, operation and maintenance, as well as a reasonable return on their respective regulated assets. The amount of costs incurred by the companies, coupled with increases in fuel and energy prices, could lead to consumer or regulatory resistance to the timely recovery of such costs, thereby adversely affecting our financial position, results of operations and cash flows.

The FERC has jurisdiction over our transmission costs recovery and our allowed ROEs. Certain outside parties have filed four complaints against all electric companies under the jurisdiction of ISO-NE alleging that our allowed ROEs are unjust and unreasonable. An adverse decision in any of these four complaintsrequire unplanned expenditures, which could adversely affect our financial position, results of operations and cash flows.

FERC's policy has encouraged competitionOur ability to properly operate our transmission and distribution systems is critical to the financial performance of our business. Our transmission and distribution businesses face several operational risks, including the breakdown, failure of, or damage to operating equipment, information technology systems, or processes, especially due to age; labor disputes; disruptions in the delivery of electricity, natural gas and water; increased capital expenditure requirements, including those due to environmental regulation; catastrophic events resulting from equipment failures such as wildfires and explosions, or external events such as a solar event, an electromagnetic event, or other similar occurrences; increasingly severe weather conditions due to climate change beyond equipment and plant design capacity; human error; global supply chain disruptions; and potential claims for property damage or personal injuries beyond the scope of our insurance coverage. Many of our transmission projects even within existingare expected to alleviate identified reliability issues and reduce customers' costs. However, if the in-service date for one or more of these projects is delayed due to economic events or factors, or regulatory or other delays, including permitting and siting, the risk of failures in the electric transmission system may increase. We also implement new information technology systems from time to time, which may disrupt operations. Any failure of our transmission and distribution systems to operate as planned may result in increased capital costs, reduced earnings or unplanned increases in operations and maintenance costs. The inability to recover a significant amount of such costs could have an adverse effect on our financial position, results of operations and cash flows.

New technology and alternative energy sources could adversely affect our operations and financial results.

Advances in technology that reduce the costs of alternative methods of producing electric energy to a level that is competitive with that of current electric production methods, could result in loss of market share and customers, and may require us to make significant expenditures to remain competitive. These changes in technology, including micro-grids and advances in energy or battery storage, could also alter the channels through which electric customers buy or utilize energy, which could reduce our revenues or increase our expenses. Economic downturns or periods of high energy supply costs typically can lead to the development of legislative and regulatory policy designed to promote reductions in energy consumption and increased energy efficiency and self-generation by customers. Additionally, in response to risks posed by climate change, we may need to make investments in our system including upgrades or retrofits to meet enhanced design criteria, which can incur additional costs over conventional solutions.

We rely on third-party suppliers for equipment, materials, and services and we outsource certain business functions to third-party suppliers and service territoriesproviders, and substandard performance or inability to fulfill obligations by those third parties could harm our business, reputation and results of electric companies. Implementationoperations.

We outsource certain services to third parties in areas including information technology, transaction processing, human resources, payroll and payroll processing and certain operational areas. Outsourcing of FERC's goals, including within our service territories, mayservices to third parties could expose us to competitionsubstandard quality of service delivery or substandard deliverables, which may result in missed deadlines or other timeliness issues, non-compliance (including with applicable legal requirements and industry standards) or reputational harm, which could negatively impact our results of operations. Our contractual arrangements with these contractors typically include performance standards, progress payments, insurance requirements and security for constructionperformance. The global supply chain of transmission projects, additional regulatory considerations,goods and potential delay with respectservices remains volatile, and as a result, we are seeing delivery delays of certain goods, particularly certain types
20


of transformers. If significant difficulties in the global supply chain cycle or inflationary impacts were to future transmission projects, which mayworsen, they could adversely affect our results of operations, and lower rate base growth.

or adversely affect our ability to work with regulators, unions, customers or employees.

Changes in tax laws, as well asThe loss of key personnel, the potential tax effects of business decisionsinability to hire and retain qualified employees, or the failure to maintain a positive relationship with our workforce could negatively impact our business, results of operations (including our expected project returns from our planned offshore wind facilities), financial condition and cash flows.

We are exposed to significant reputational risks, which make us vulnerable to increased regulatory oversight or other sanctions.

Because utility companies, including our electric, natural gas and water utility subsidiaries, have large customer bases, they are subject to adverse publicity focused on the reliability of their distribution services and the speed with which they are able to respond to electric outages, natural gas leaks and similar interruptions caused by storm damage or other unanticipated events. Adverse publicity of this nature could harm our reputation and the reputation of our subsidiaries; may make state legislatures, utility commissions and other regulatory authorities less likely to view us in a favorable light; and may cause us to be subject to less favorable legislative and regulatory outcomes or increased regulatory oversight. Unfavorable regulatory outcomes can include more stringent laws and regulations governing our operations, such as reliability and customer service quality standards or vegetation management requirements, as well as fines, penalties or other sanctions or requirements.

Costs of compliance with environmental laws and regulations, including those related to climate change, may increase and have an adverse effect on our business, financial position and results of operations.

Our subsidiaries' operations depend on the continued efforts of our employees. Retaining key employees and maintaining the ability to attract new employees are subjectimportant to extensive federal, stateboth our operational and local environmental statutes, rulesfinancial performance. We cannot guarantee that any member of our management or any key employee at the Eversource parent or subsidiary level will continue to serve in any capacity for any particular period of time. Our workforce in our subsidiaries includes many workers with highly specialized skills maintaining and regulationsservicing the electric, natural gas and water infrastructure that govern, among other things, water quality, water discharges,cannot be quickly replaced due to the managementtechnically complex work they perform. We have developed strategic workforce plans to identify key functions and proactively implement plans to assure a ready and qualified workforce, but we cannot predict the impact of hazardousthese plans on our ability to hire and solid waste, and air emissions. Compliance with these requirements requires usretain key employees. Labor disputes, work stoppages or an inability to incur significant costs relating to environmental monitoring, maintenance and upgradingnegotiate future collective bargaining agreements on commercially reasonable terms, as well as the increased competition for talent or the intentional misconduct of facilities, remediation and permitting.

The costs of compliance with existing legal requirementsemployees or legal requirements not yet adoptedcontractors, may increase in the future. An increase in such costs, unless promptly recovered, couldalso have an adverse impacteffect on our business, and our financial position and results of operations and cash flows.

For further information, see Item 1, Business - Other Regulatory and Environmental Matters, included in this Annual Report on Form 10-K.operations.

Financial, Economic, and Market Risks:

Our goodwill is recorded at an amount that, if impaired and written down, could adversely affect our future operating results and total capitalization.

We have a significant amount of goodwill on our consolidated balance sheet, which, as of December 31, 2020, totaled $4.4 billion. The carrying value of goodwill represents the fair value of an acquired business in excess of the fair value of identifiable assets and liabilities as of the acquisition date. We test our goodwill balances for impairment on an annual basis or whenever events occur, or circumstances change that would indicate a potential for impairment. A determination that goodwill is deemed to be impaired would result in a non-cash charge that could materially adversely affect our financial position, results of operations and total capitalization. The annual goodwill impairment test in 2020 resulted in a conclusion that our goodwill was not impaired.

Our counterparties may not meet their obligations to us or may elect to exercise their termination rights, which could adversely affect our earnings.

We are exposed to the risk that counterparties to various arrangements that owe us money, have contracted to supply us with energy or other commodities or services, or that work with us as strategic partners, including on significant capital projects, will not be able to perform their obligations, will terminate such arrangements or, with respect to our credit facilities, fail to honor their commitments. Should any of these counterparties fail to perform their obligations or terminate such arrangements, we might be forced to replace the underlying commitment at higher market prices and/or have to delay the completion of, or cancel, a capital project. Should any lenders under our credit facilities fail to perform, the level of borrowing capacity under those arrangements could decrease. In any such events, our financial position, results of operations, or cash flows could be adversely affected.

Limits on our access to, or increases in, the cost of capital may adversely impact our ability to execute our business plan.

We use short-term debt and the long-term capital markets as a significant source of liquidity and funding for capital requirements not obtained from our operating cash flow. If access to these sources of liquidity becomes constrained, our ability to implement our business strategy could be adversely affected. In addition, higher interest rates wouldhave increased and may continue to increase in the future. As a result, interest rates on future credit facilities and debt offerings could be higher than current levels, causing our cost of borrowing,financing costs to increase accordingly, which could adversely impact our financial position, results of operations.operations and cash flows. A downgrade of our credit ratings or events beyond our control, such as a disruption in global capital and credit markets, could increase our cost of borrowing and cost of capital or restrict our ability to access the capital markets and negatively affect our ability to maintain and to expand our businesses.

Market performance or changes in assumptions may require us to make significant contributions to our pension and other postretirement benefit plans.

We provide a defined benefit pension plan and other postretirement benefits for a substantial number of employees, former employees and retirees. Our future pension obligations, costs and liabilities are highly dependent on a variety of factors, many of which are beyond our control. These factors include estimated investment returns, interest rates, discount rates, health care cost trends, benefit changes, salary increases and the demographics of plan participants. If our assumptions prove to be inaccurate, our future costs could increase significantly. In addition, various factors, including underperformance of plan investments and changes in law or regulation, could increase the amount of contributions required to fund our pension plan in the future. Additional large funding requirements, when combined with the financing requirements of our construction
20


program, could impact the timing, amounts, and number of future financings and negatively affect our financial position, results of operations and cash flows.

Goodwill, investments in equity method investments, and long-lived assets if impaired and written down, could adversely affect our future operating results and total capitalization.

We have a significant amount of goodwill on our consolidated balance sheet, which, as of December 31, 2023, totaled $4.53 billion. The carrying value of goodwill represents the fair value of an acquired business in excess of the fair value of identifiable assets and liabilities as of the acquisition date. We test our goodwill balances for impairment on an annual basis or whenever events occur, or circumstances change that would indicate a potential for impairment. A determination that goodwill is deemed to be impaired would result in a non-cash charge that could materially adversely affect our financial position, results of operations and total capitalization.

We assess our investments (recorded as either long-lived assets or equity method investments) for impairment whenever events or circumstances indicate that the carrying amount of the investment may not be recoverable. To the extent the value of the investment becomes impaired, the impairment charge could have a material adverse effect on our financial condition and results of operations.

Our counterparties may not meet their obligations to us or may elect to exercise their termination rights, which could adversely affect our earnings.

We are exposed to the risk that counterparties to various arrangements that owe us money, have contracted to supply us with energy or other commodities or services, or that work with us as strategic partners, including on significant capital projects, will not be able to perform their obligations, will terminate such arrangements or, with respect to our credit facilities, fail to honor their commitments. Should any of these counterparties fail to perform their obligations or terminate such arrangements, we might be forced to replace the underlying commitment at higher market prices and/or have to delay the completion of, or cancel, a capital project. Should any lenders under our credit facilities fail to perform, the level of borrowing capacity under those arrangements could decrease. In any such events, our financial position, results of operations, or cash flows could be adversely affected.

As a holding company with no revenue-generating operations, Eversource parent's liquidity is dependent on dividends from its subsidiaries, its commercial paper program, and its ability to access the long-term debt and equity capital markets.

Eversource parent is a holding company and as such, has no revenue-generating operations of its own. Its ability to meet its debt service obligations and to pay dividends on its common shares is largely dependent on the ability of its subsidiaries to pay dividends to, or repay borrowings from, Eversource parent, and/or Eversource parent's ability to access its commercial paper program or the long-term debt and equity capital markets. Prior to funding Eversource parent, the subsidiary companies have financial obligations that must be satisfied, including among others, their operating expenses, debt service, preferred dividends of certain subsidiaries, and obligations to trade creditors. Should the subsidiary companies not be able to pay dividends or repay funds due to Eversource parent, or if Eversource parent cannot access its commercial paper programs or the long-term debt and equity capital markets, Eversource parent's ability to pay interest, dividends and its own debt obligations would be restricted.

Item 1B.    Unresolved Staff Comments

We do not have any unresolved SEC staff comments.

Item 1C. Cybersecurity

The Company’s policies, practices and technologies allow it to protect its information systems and operational assets from threats. The Board of Trustees and its Finance and Audit Committees continue to provide substantial and focused attention to cyber and system security. The Finance Committee of the Board of Trustees is responsible for oversight of the Company’s enterprise-wide risks, including risks associated with cyber and physical security, and the Company’s programs and practices to monitor and mitigate these risks.

Management prepares comprehensive cyber security reports that are discussed at each meeting of the Finance Committee. The reports focus on the changing threat landscape and the risks to the Company, describe Eversource’s cyber security drills and exercises, attempted and actual breaches on our systems, cyber incidents within the utility industry and around the world, and mitigation strategies. In addition, third-party experts of cyber security risks provide periodic assessments to the utility industry and the Company in particular to the Finance Committee. The Company regularly reviews and updates its cyber and system security programs, and the Finance Committee continues to enhance its robust oversight activities, including meetings with financial, information technology, legal and accounting management, other members of the Board, representatives of the Company’s independent registered public accounting firm, and outside advisors and experts in cyber security risks, at which cyber and system security programs and issues that might affect the Company’s financial statements and operational systems are discussed.

The Company has a robust Enterprise Risk Management Program which has identified cyber security as a top enterprise risk. The managing and monitoring of risks are the responsibility of the Company’s Risk Committee, which meets quarterly and is chaired by the Chief Financial Officer.

The Company is committed to continuous monitoring and assessment of cyber security controls. The Chief Information Security Officer is responsible for developing, implementing, and enforcing our cyber security program and information security policies to protect the Company’s information systems and operational assets. The Chief Information Security Officer position requires at least 15 years of relevant information security experience and relevant security certifications. The Chief Information Security Officer reports directly to the Chief Information Officer and provides regular updates to the executive management team. Our Chief Information Security Officer has over 20 years of relevant experience.

The Company created a Cyber Governance Committee, which includes the Chief Information Security Officer, Chief Information Technology Officer, Chief Accounting Officer, members of the executive management team, and other assurance functions such as Corporate Compliance, Enterprise Risk Management, and Internal Audit.

To assess, identify and manage material risks from cybersecurity threats and to prevent, detect, mitigate and remediate a cyber security or ransomware incident, the following key processes and programs have been implemented and are performed by the Company’s Cyber Security Group, which is overseen by the Chief Information Security Officer:

Implementation of security solutions and standards based on industry best practices to prevent unauthorized access. The Company’s cyber program has been modeled after the National Institute of Standards and Technology framework; a widely accepted framework utilized by critical infrastructure industries.
Periodic external assessments, including outside system access testing, are performed. Rigorous auditing of all safeguards is performed on a regular basis. Risk assessments are held to identify and address new and changing risks to protect systems and sensitive data. Identified areas are monitored and improvements are implemented.
Eversource participates in information sharing programs both within and outside the utility industry, including with the U.S. government and industry organizations, to be able to identify and respond to emerging threats.
The Company maintains current incident response and business continuity plans, which are periodically updated and tested.
Network activity is monitored on an ongoing basis.
Anti-phishing and malware tools are utilized and assessed.
Employees are trained to recognize phishing attempts and are periodically tested. Results of phishing testing are benchmarked against other companies both within and outside the utility industry.

22


Specific to third parties, Eversource has implemented formal screening processes for any applicable vendors by the Company’s Cyber Security Group as part of the Procurement process. The vendors are risk ranked based on the type of work being performed. Periodic rescreening is performed on critical vendors. Vendors are required to attest to their business continuity programs and provide evidence of appropriate insurance and indemnification agreements. The Company bars sourcing from countries included on the Department of Homeland Security’s list of Prohibited Nations to further protect the Company’s supply chain. The Company maintains cyber insurance which covers breaches of networks and operational technology. Our existing insurance limits may be inadequate to cover a material cyber incident. This could expose us to potentially significant claims and damages.

As of December 31, 2023, there were no risks from cybersecurity threats, including due to any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the Company, its business strategy, results of operations, or financial condition.

EVERSOURCE ENERGY AND SUBSIDIARIES

The following discussion and analysis should be read in conjunction with our consolidated financial statements and related combined notes included in this combined Annual Report on Form 10-K.  References in this combined Annual Report on Form 10-K to "Eversource," the "Company," "we," "us," and "our" refer to Eversource Energy and its consolidated subsidiaries.  All per-share amounts are reported on a diluted basis.  The consolidated financial statements of Eversource, NSTAR Electric and PSNH and the financial statements of CL&P are herein collectively referred to as the "financial statements."  Our discussion of fiscal year 20202023 compared to fiscal year 20192022 is included herein. Unless expressly stated otherwise, for discussion and analysis of fiscal year 20182021 items and of fiscal year 20192022 compared to fiscal year 2018,2021, please refer to Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, in our combined 20222019 Annual Report on Form 10-K, which is incorporated herein by reference.

Refer to the Glossary of Terms included in this combined Annual Report on Form 10-K for abbreviations and acronyms used throughout this Management's Discussion and Analysis of Financial Condition and Results of Operations.  

The only common equity securities that are publicly traded are common shares of Eversource. Our earnings discussion includes financial measures that are not recognized under GAAP (non-GAAP) referencing our earnings and EPS excluding the impairment charges for the offshore wind investments, a loss on the disposition of land that was initially acquired to construct the Northern Pass Transmission project and was subsequently abandoned, certain transaction and transition costs, and our earnings and EPS excluding charges at CL&P related to an October 2021 settlement agreement that included credits to customers and funding of various customer assistance initiatives and a 2021 storm performance penalty imposed on CL&P by PURA. EPS by business is also a non-GAAP financial measure and is calculated by dividing the Net Income Attributable to Common Shareholders of each business by the weighted average diluted Eversource common shares outstanding for the period. The earnings and EPS of each business discussed below do not represent a direct legal interest in the assets and liabilities of such business, but rather represent a direct interest in our assets and liabilities as a whole. EPS by business is a financial measure not recognized under GAAP, calculated by dividing the Net Income Attributable to Common Shareholders of each business by the weighted average diluted Eversource common shares outstanding for the period. Our earnings discussion also includes non-GAAP financial measures referencing our 2020 earnings and EPS excluding certain acquisition costs related to our purchase of the assets of Columbia Gas of Massachusetts and our 2019 earnings and EPS excluding the impairment charge for the NPT project.

We use these non-GAAP financial measures to evaluate and provide details of earnings results by business and to more fully compare and explain our 2020 and 2019 results without including these items. This information is among the primary indicators we use as a basis for evaluating performance and planning and forecasting of future periods. We believe the acquisitionimpacts of the impairment charges for the offshore wind investments, the loss on the disposition of land associated with an abandoned project, transaction and transition costs, and the NPT impairment chargeCL&P October 2021 settlement agreement, and the 2021 storm performance penalty imposed on CL&P by PURA are not indicative of our ongoing costs and performance. We view these charges as not directly related to the ongoing operations of the business and therefore not an indicator of baseline operating performance. Due to the nature and significance of the effect of these items on Net Income Attributable to Common Shareholders and EPS, we believe that the non-GAAP presentation is a more meaningful representation of our financial performance and provides additional and useful information to readers of this report in analyzing historical and future performance of our business. These non-GAAP financial measures should not be considered as alternatives to reported Net Income Attributable to Common Shareholders or EPS determined in accordance with GAAP as indicators of operating performance.

The outbreak of COVID-19 has not resulted in significant operational or earnings impacts. We believe that we have in place, or are developing, successful mechanisms with our state regulatory commissions that allow, or will allow, us to recover our incremental costs associated with COVID-19, which include uncollectible customer receivable expenses. We are continuing to closely monitor the COVID-19 pandemic, and we continue to operate under our pandemic response plan.

Strategic and Regulatory Items:

On October 9, 2020, Eversource completed the acquisition of certain assets and liabilities that comprised NiSource’s natural gas distribution business in Massachusetts, CMA, for a cash purchase price of $1.1 billion, plus a target working capital amount of $69.6 million, which is subject to adjustment to reflect actual working capital as of the closing date. On October 7, 2020, the DPU approved the rate plan related to the acquisition. The approved rate stabilization plan includes base distribution rate increases of $13 million on November 1, 2021 and $10 million on November 1, 2022. The settlement agreement includes two rate base resets during an eight-year rate plan, occurring on November 1, 2024 and November 1, 2027.

On December 15, 2020,February 13, 2024, we initiated an exploratory assessment of monetizing our water distribution business and are exploring the NHPUC approvedpotential sale of the business.

Strategic Developments:

On February 13, 2024, Eversource announced that it has executed an October 9, 2020 settlement agreement that included a permanent rate increaseto sell its existing 50 percent interests in the South Fork Wind and Revolution Wind projects to Global Infrastructure Partners (GIP). As part of $45.0this transaction, Eversource expects to receive approximately $1.1 billion of cash proceeds upon closing, which includes the sales value related to the 10 percent energy community ITC adder of approximately $170 million effective January 1, 2021 at PSNH. PSNH was also permitted three step increases, effective January 1, 2021, August 1, 2021,related to Revolution Wind, and August 1, 2022, to reflect plant additions in calendar years 2019, 2020 and 2021, respectively. The settlement agreement allowedexit these projects while retaining certain cost sharing obligations for the effectconstruction of Revolution Wind. The purchase price is subject to future post-closing adjustment payments based on, among other things, the progress, timing and expense of construction at each project. The cost sharing obligations provide that Eversource would share equally with GIP in GIP’s funding obligations for up to approximately $240 million of incremental capital expenditure overruns incurred during the construction phase for the Revolution Wind project, after which GIP’s obligations for any additional capital expenditure overruns would be shared equally by Eversource and Ørsted. Additionally, Eversource’s financial exposure will be adjusted by certain purchase price adjustments to be made following commercial operation of the permanentRevolution Wind project and closing of South Fork as a result of final project economics, which includes Eversource’s obligation to maintain GIP’s internal rate increaseof return for each project as specified in the agreement. Eversource currently expects that South Fork Wind will reach full commercial operation prior to be extended back to the temporary rate period. In lieu of a customer rate increase for this recoupment of revenue, the NHPUC directed a portionclosing of the total EDIT regulatory liabilitysale with GIP and Eversource does not expect any material cost sharing or other purchase price adjustment payments for South Fork Wind. Closing of the transaction is currently expected to offset bill impacts to customers.occur in mid-2024.

On October 30, 2020,January 24, 2024, Ørsted signed an agreement with Eversource to acquire Eversource’s 50 percent share of Sunrise Wind. The sale is subject to the DPU approvedsuccessful selection of Sunrise Wind in the ongoing New York fourth solicitation for offshore wind capacity, signing of an NSTAR Gas base distribution rate increaseOREC contract with NYSERDA, finalization of $23.0 million effective November 1, 2020. NSTAR Gas' 2019 plant additions are allowed recovery beginning on November 1, 2021. sale agreements, receipt of final federal construction permits, and relevant regulatory approvals. If Sunrise Wind is not successful in the solicitation, then the existing OREC contract for Sunrise Wind will be cancelled according to the state’s requirements, and Eversource and Ørsted’s joint venture for Sunrise Wind will remain in place. In that scenario, Ørsted and Eversource would then assess their options in determining the best path forward for Sunrise Wind and its assets, which include the BOEM offshore lease area.

InOn January 2021, BOEM released its Draft Environmental Impact Statement (EIS)25, 2024, Eversource and Ørsted submitted a new proposal for Sunrise Wind in the South Fork Wind project, which assessed the environmental, social, and economic impacts of constructing the project.New York fourth offshore wind solicitation.

All wind turbines are expected to be installed and caused volatility inplaced into service by the financial markets. Due to the inherent uncertaintyend of the unprecedented and evolving situation, we continue to closely monitor how COVID-19 related developments affect Eversource. Based on available information, we have not experienced significant impacts directly related to the pandemic that have adversely affected our current operations or results of operations. The extent of the impact to us in the future will vary and depend in large part on the duration, scope and severity of the pandemic and the timing and extent of COVID-19 relief legislation, and the resulting impact on economic, health care and capital market conditions. The future impact will also depend on the outcome of planned proceedings before our state regulatory commissions to recover our incremental costs associated with COVID-19, which include uncollectible customer receivable expenses.March 2024.

Operational: We provide a critical service to our customers and have taken extensive measures to maintain its safety and reliability. We have implemented our company-wide pandemic plan, which guides our emergency response, business continuity, and the precautionary measures we are taking to ensure the safety, health, and well-being of our employees, our customers, and our communities. We continue to adjust our company-wide pandemic plan to address various scenarios, including reduced workforce levels and limited mutual aid in the event of a significant storm event, and have implemented protective measures to mitigate the impact of COVID-19 on our workforce. We have implemented work from home policies where appropriate, resulting in nearly half of our employees working remotely. For our employees performing essential functions that are required onsite, such as field crews and system operations, we have taken significant safety measures, including establishing social distancing measures, the use of personal protective equipment, increasing facility sanitization efforts, and enabling critical operations to be shifted to different control center locations if necessary. At this time, our workforce staffing levels continue to enable us to safely and reliably deliver our critical services to customers.

We continue to prepare for the re-entry of our employees working remotely. Our re-entry plan includes a multi-phase approach that is measured and gradual. The plan is informed by public health guidance with the safety of our employees and customers as our highest priority. We are in the early phase of our re-entry plan and have returned fewer than 100 remote employees to the workplace. We have had increased short duration return to work for critical business needs, such as storm response and essential training. State and federal guidelines, external conditions, and critical business priorities continue to inform the pace of our re-entry plan. Significant health and safety measures and pandemic protocols will remain in place, including social distancing requirements, the use of personal protective equipment, sanitization efforts and employee training, for all employees currently working onsite and specific plans have been developed for our eventual re-entry to the workplace.

In mid-March, we suspended non-critical work inside customer premises, which included energy audits inside our customers’ homes and businesses. These activities resumed in early July with the implementation of new health and safety guidelines for the restart of energy efficiency services to customers. This delay did not have a significant impact on our 2020 spending levels or incentives earned. As of the date of our filing, we do not expect a significant impact on our 2021 energy efficiency program spending and efforts, which assumes the continuation of energy efficiency programs throughout 2021. Actual energy efficiency spending levels will depend on the extent and duration of the pandemic.

Among the states we serve, COVID-19 had initially spread in a rapid manner in Connecticut and Massachusetts during the outbreak that began in mid-March. During the summer, these states had seen a decrease in the infection rate and daily confirmed cases, as well as more capacity in hospitals, and improved testing availability and contact tracing, as compared to the initial outbreak. Beginning in October, the spread of COVID-19 began to increase at a significant pace, surpassing infection levels from the initial outbreak, peaking in December 2020 and January 2021 in each of the states we serve. Since those peak levels, there has been a downward trend in the daily confirmed cases, infection rates and positive test rates.

Financial: Overall, our future financial position, results of operations, and cash flows could be negatively impacted by COVID-19 as it relates to the collectability of customer receivables and customer payment plans, elimination of late payment revenues, lower sales volumes primarily from PSNH's commercial and industrial customers, energy efficiency spending levels and incentives earned, and increased expenses for cleaning and supplies for personal protective equipment. Other potential negative financial impacts relate to market volatility on our equity and debt securities, access to, as well as cost of, capital resources, and the ability of various third-party vendors and suppliers to fulfill their obligations.

As of December 31, 2020, our allowance for uncollectible customer receivable balance of $358.9 million, of which $194.8 million relates to hardship accounts that are specifically recovered in rates charged to customers, adequately reflected the collection risk and net realizable value for our receivables.  We continue to evaluate the adequacy of the uncollectible allowance based on an ongoing assessment of accounts receivable collections and customer payment trends, economic conditions, delinquency statistics, aging-based quantitative assessments, the impact on residential customer bills because of energy usage and change in rates, flexible payment plans and financial hardship arrearage management programs being offered to customers, and COVID-19 developments, including any potential federal governmental pandemic relief programs and the expansion of unemployment benefit initiatives, which help to mitigate the potential for increasing customer account delinquencies. Additionally, management considered past economic declines and corresponding uncollectible reserves as part of the current assessment. This evaluation has shown that our operating companies have experienced an increase in aged receivables and some lower cash collections from customers because of the moratorium on disconnections and the economic slowdown resulting from the COVID-19 pandemic.

Based upon the evaluation performed, in 2020, we increased the allowance for uncollectible accounts for amounts incurred as a result of COVID-19 by $31.5 million for Eversource ($2.8 million for CL&P, $11.0 million for NSTAR Electric, $2.3 million for PSNH and $15.4 million at our natural gas businesses). These COVID-19 related uncollectible amounts were deferred either as incremental regulatory costs or deferred through existing regulatory tracking mechanisms that recover uncollectible energy supply costs, as we believe it is probable that these costs will ultimately be recovered from customers in rates. We believe that we have in place, or are developing, successful mechanisms with our state regulatory commissions that allow, or will allow, us to recover our incremental costs associated with COVID-19, which include uncollectible customer receivable expenses, while balancing the impact on our customers’ bills and our operating cash flows. 

In March 2020, Connecticut, Massachusetts and New Hampshire each established moratoria on disconnections of residential and commercial customers for non-payment for utility service.  In all three states, a moratorium for lower income hardship residential customers will remain in place through the normal state regulated winter moratorium that ends in the spring of 2021.  In Connecticut and New Hampshire, the moratorium for all remaining customers has expired.  In Massachusetts, the moratorium on commercial utility disconnections ended on September 1, 2020 and the moratorium on residential non-hardship disconnections was extended to April 1, 2021.

We continue to work closely with our state regulatory commissions and consumer advocates on customer assistance measures, including payment plan options in order to mitigate the impact on customer rates in the future, as well as financial hardship and arrearage management programs for those customers who are unable to pay their utility bills. We developed these long-term solutions for customers in order to help minimize the extent of the impact of COVID-19 on customer receivable balances and customers’ affordability in light of the current financial impact they may experience. Our operating companies also eliminated late payment charges beginning in March 2020, with New Hampshire being the only state with a defined restart date of April 1, 2021. In 2020, we have waived $6.1 million of late payment charges that would have otherwise been recognized within revenues as a benefit to pre-tax earnings.

For the year ended December 31, 2020, net incremental costs incurred as a result of COVID-19 totaled $35.2 million and related to uncollectible expense that impacts earnings, facilities and fleet cleaning, sanitizing costs and supplies for personal protective equipment, net of cost savings. We have deferred $24.0 million of these net incremental COVID-19 costs on the balance sheet, of which $15.8 million of that deferral related to uncollectible expense that impacts earnings and $8.2 million related to cleaning and supplies for personal protective equipment. Incremental COVID-19 expenses that reduced pre-tax earnings totaled $11.1 million on the statement of income. For further information on Connecticut, Massachusetts and New Hampshire COVID-19-related regulatory developments, see "Regulatory Developments and Rate Matters - COVID-19 Regulatory Dockets" included in this Management’s Discussion and Analysis.

An extended economic slowdown has resulted in lower demand for electricity, natural gas and/or water by our commercial and industrial customers. However, fluctuations in retail sales volumes for CL&P, NSTAR Electric, Yankee Gas, NSTAR Gas, EGMA, and our Connecticut water distribution business do not materially impact earnings due to their respective state regulatory commission-approved distribution revenue decoupling mechanisms. Overall, our risk of exposure to lower demand and resulting lost sales revenues is limited as our regulated utilities are under cost-of-service rates with revenue decoupling mechanisms (with the exception of PSNH) and a significant portion of uncollectible expenses are tracked for ultimate recovery. Our revenue decoupling mechanisms allow us to recover an annual revenue stream that is decoupled from actual customer usage, and each is reconciled each year as part of our annual decoupling filing in each respective jurisdiction.

We continue to monitor Eversource parent’s and our operating companies’ ability to access the global capital and credit markets. At the onset of the pandemic in the United States, liquidity in the commercial paper credit market began to deteriorate rapidly. However, federal legislative actions, including actions taken by the Federal Reserve, have provided sufficient liquidity and stabilization of the credit markets. An extended economic slowdown could result in Eversource parent and our operating companies finding difficulty in accessing necessary capital resources and incurring higher costs for those capital resources. At this time, based on available information and the current market trends, we believe we will continue to have access to needed liquidity and capital resources to successfully execute our projected capital expenditures and strategies. We expect our existing borrowing availability under our commercial paper programs, our existing revolving credit facilities that serve to backstop those commercial paper programs, in addition to access to the debt and equity markets, will be sufficient to meet our future liquidity and capital resource needs.

Our electric distribution segment earnings increased $30.7$15.2 million in 2020,2023, as compared to 2019,2022, due primarily to a base distribution rate increases at CL&Pincrease effective MayJanuary 1, 2020 and May 1, 2019,2023 at NSTAR Electric, effective January 1, 2020, and at PSNH effective July 1, 2019, higher earnings from CL&P's capital trackertracking mechanism due to increased electric system improvements, andan increase in interest income primarily on regulatory deferrals, the impact of a new regulatory tracking mechanism at PSNH that allows for the PSNH rate settlement agreement approved in December 2020. Therecovery of previously incurred operating expenses associated with poles acquired on May 1, 2023, and higher AFUDC equity income. Those earnings increase wasincreases were partially offset by higher operations and maintenance expense, (primarily attributable to higher storm restoration costs),interest expense, higher property and other tax expense, higher depreciation expense higher property tax expense, higher interest expense, and the absence of the 2019 recognition of carrying charges on PSNH's 2013 through 2016 storm costs approved for recovery.lower pension income.
 
Our electric transmission segment earnings increased $246.0$46.8 million in 2020,2023, as compared to 2019, due primarily to the absence in 2020 of the 2019 impairment of NPT, which resulted in an after-tax charge of $204.4 million, or $0.64 per share. Excluding the NPT impairment charge, earnings increased $41.6 million in 2020, as compared to 2019,2022, due primarily to a higher transmission rate base as a result of our continued investment in our transmission infrastructure and a higher benefit from the annual billing and cost reconciliation filing with FERC.lower effective tax rate.

Those earnings decreases were partially offset by higher earnings from capital trackertracking mechanisms due to continued investments in natural gas infrastructure, base distribution rate increases effective November 1, 2023 and lowerNovember 1, 2022 at NSTAR Gas and effective November 1, 2022 at EGMA, and an increase in interest expense due to a property tax settlement. EGMA's natural gas distribution business earned $13.9 million from October 9, 2020 through December 31, 2020. The earnings increase was partially offset by higher operations and maintenance expense and higher depreciation expense.income primarily on regulatory deferrals.

Our water distribution segment earnings increased $6.3decreased $3.7 million in 2020,2023, as compared to 2019,2022, due primarily to an after-tax gain of $3.5 million on the sale of the water systemhigher depreciation, operations and treatment plant of the Hingham, Massachusetts business, higher revenues from our Connecticut business' capital tracker mechanism due to increased infrastructure improvements, and a gain on the sale of land, partially offset by higher property taxmaintenance expense and a higher effective tax rate.interest expense.

(2) The proceeds from these Eversource parent issuances funded a portion of the purchase price for the CMA asset acquisition and refinanced short-term borrowings.

In January 2021, PSNH provided a redemption noticeyear due to the holders of the PSNH 4.050% Series Q First Mortgage Bonds that PSNH will redeem the $122 million of bonds on March 1, 2021, the par call date, in advance of the June 1, 2021 maturity date.

Rate Reduction Bonds: PSNH's RRB payments consist of principal and interest and are paid semi-annually. PSNH paid $43.2 million of RRB principal payments and $20.2 million of interest payments in 2020, and $52.3 million of RRB principal payments and $26.8 million of interest payments in 2019.

Common Share Issuances and 2019 Forward Sale Agreement: On June 15, 2020, Eversource completed an equity offering of 6,000,000 common shares at a price per share of $86.26. Eversource used the net proceeds of this offering to fund a portion of the purchase of the assets of CMA that closed on October 9, 2020. The issuance of these common shares resulted in proceeds of $509.2 million, net of issuance costs.

In June 2019, Eversource completed an equity offering consisting of 5,980,000 common shares issued directly by the Company and 11,960,000 common shares issuable pursuant to a forward sale agreement with an investment bank. Under the forward sale agreement, 11,960,000 common shares were borrowed from third parties and sold by the underwriters. The forward sale agreement allowed Eversource, at its election and prior to May 29, 2020, to physically settle the forward sale agreement by issuing common shares in exchange for net proceeds at the then-applicable forward sale price specified by the agreement (initially, $71.48 per share) or, alternatively, to settle the forward sale agreement in whole or in part through the delivery or receipt of shares or cash. The forward sale price was subject to adjustment daily based on a floating interest rate factor and would decrease in respect of certain fixed amounts specified in the agreement, such as dividends.

Eversource issued 6,000,000 common shares under the forward sale agreement in December 2019. On March 23, 2020, Eversource physically settled a portion of the forward sale agreement by delivering 1,500,000 common shares in exchange for net proceeds of $105.7 million. Subsequently, on March 26, 2020, Eversource physically settled the remaining portion of the forward sale agreement by delivering 4,460,000 common shares in exchange for net proceeds of $314.1 million. The forward sale price used to determine the cash proceeds received by Eversource was calculated based on the initial forward sale price, as adjusted in accordance with the forward sale agreement.

The March and June 2020 common share issuances of 5,960,000 and 6,000,000, respectively, resulted in total proceeds of $929.0 million, net of issuance costs. The June and December 2019 common share issuances of 5,980,000 and 6,000,000, respectively, resulted in total proceeds of $852.3 million. These issuances were reflected in shareholders’ equity and as financing activities on the statements of cash flows.

Issuances of shares under the forward sale agreement were classified as equity transactions. Accordingly, no amounts relating to the forward sale agreement were recorded in the financial statements until settlements took place. Prior to any settlements, the only impact of the forward sale agreement to the financial statements was the inclusion of incremental shares within the calculation of diluted EPS using the treasury stock method. See Note 21, "Earnings Per Share," to the financial statements for information on the forward sale agreement’s impact on the calculation of diluted EPS.

Eversource used the net proceeds received from the direct issuance of common shares and the net proceeds received from settlement of the forward sale agreement to repay short-term debt under the commercial paper program, to partially fund the purchase of the assets of CMA, to fund capital spending and clean energy initiatives, and for general corporate purposes.

Cash Flows:  Cash flows provided by operating activities totaled $1.68 billion in 2020, compared with $2.01 billion in 2019. Operating cash flows were unfavorably impacted by the timing of cash collections on our accounts receivable, the timing of collections for regulatory tracking mechanisms primarily related to transmission costs and the impact of the CL&P temporary rate suspension, andfluctuations in cash payments made in 2020 for storm restoration costs of approximately $196 million related to Tropical Storm Isaias. Also contributing to the unfavorable impact was the absence of $68.8 million in DOE Phase IV proceeds received by CYAPC and YAEC in 2019. Partially offsetting these unfavorable impacts were the favorableflows from operations (including timing of cash payments made on our accounts payable, the absence of a $29.0 million payment made in 2019 to the DOE by CYAPC to partially settle its pre-1983 spent nuclear fuel obligation,storm costs and a decrease of $10.3 million in Pension and PBOPregulatory recoveries), dividends paid, capital contributions made in 2020, as compared to 2019.

Our receivables, net of reserves, on the balance sheet have increased $206.5 million ($58.3 million at CL&P, $56.3 million at NSTAR Electric, and $20.0 million at PSNH) in 2020, as compared to 2019, due primarily to an increase in delinquent receivables from customers attributable to the moratorium on disconnections and the economic slowdown resulting from the COVID-19 pandemic. Receivables, net of reserves, also increased due to the addition of EGMA of $65.8 million as of December 31, 2020.
Cash flows provided by operating activities totaled $2.01 billion in 2019, compared with $1.83 billion in 2018.  The increase in operating cash flows was due primarily to a decrease in 2019 of approximately $148 million of major storm restoration cost payments, $116 million in lower payments made in 2019 to the DOE by CYAPC to partially settle its pre-1983 spent nuclear fuel obligation, and a $73.2 million decrease in pension and PBOP cash contributions made in 2019, as compared to 2018. Also contributing to the increase were $102.8 million of lower income tax payments made in 2019, as compared to 2018, $68.8 million in DOE Phase IV litigation proceeds received by CYAPC and YAEC in 2019, and the timing of cash collections on our accounts receivables. Partially offsetting these favorable impacts were the timing of collections for regulatory tracking mechanisms, which were significantly impacted by the timing of collections of purchased power and transmission costs at NSTAR Electric, and the timing of accounts payable cash payments and other working capital items.

In 2020, we paid cash dividends of $744.7 million and issued non-cash dividends of $22.8 million in the form of treasury shares, totaling dividends of $767.5 million, or $2.27 per common share. In 2019, we paid cash dividends of $663.2 million and issued non-cash dividends of $22.8 million in the form of treasury shares, totaling dividends of $686.0 million, or $2.14 per common share. Our quarterly common share dividend payment was $0.5675 per share in 2020, as compared to $0.535 per share in 2019.  On February 9, 2021, our Board of Trustees approved a common share dividend payment of $0.6025 per share, payable on March 31, 2021 to shareholders of record as of March 4, 2021.  The 2021 dividend represents an increase of 6.2 percent over the dividend paid in December 2020.

Beginning in 2019, Eversource issues treasury shares to satisfy awards under the Company's incentive plans, shares issued under the dividend reinvestment and share purchase plan, and matching contributions under the Eversource 401k Plan.

In 2020, CL&P, NSTAR Electric and PSNH paid $69.5 million, $262.0 million and $22.3 million, respectively, in common stock dividends to Eversource parent.  

Investments in Property, Plant and Equipment on the statements of cash flows do not include amounts incurred on capital projects but not yet paid, cost of removal, AFUDC related to equity funds, and the capitalized and deferred portions of pension and PBOP expense.  In 2020, investments for Eversource, CL&P, NSTAR Electric and PSNH were $2.94 billion, $834.0 million, $907.0 million and $342.6 million, respectively.  

On October 9, 2020, Eversource completed the CMA asset acquisition for a cash purchase price of $1.1 billion plus a target working capital amount of $69.6 million, which is subject to adjustment to reflect actual working capital as of the closing date. The purchase price included in investing cash outflows on the statement of cash flows of $1.11 billion reflects the payment to NiSource, which excludes restricted cash accounts Eversource funded of $56.8 million.

Eversource, CL&P, NSTAR Electric and PSNH each uses its available capital resources to fund its respective construction expenditures, meet debt requirements, pay operating costs, including storm-related costs, pay dividends, and fund other corporate obligations, such as pension contributions. Eversource's regulated companies recover their electric, natural gas and water distribution construction expenditures as the related project costs are depreciated over the life of the assets. This impacts the timing of the revenue stream designed to fully recover the total investment plus a return on the equity and debt used to finance the investments. The current growth in Eversource's construction expenditures utilizesregulated companies spend a significant amount of cash foron capital improvements and construction projects that have a long-term return on investment and recovery period, totaling approximately $2.94 billion in cash capital spend in 2020.period. In addition, Eversource'sEversource uses its capital resources to fund investments in its offshore wind business, totaled $237.8 million in 2020, which are recognized as long-term assets. These factors have resulted in current liabilities exceeding current assets by $1.78$2.09 billion, $316.3$308.5 million and $271.3$143.6 million at Eversource, NSTAR Electric and PSNH, respectively, as of December 31, 2020.2023.

We expect the future operating cash flows of Eversource, CL&P, NSTAR Electric and PSNH, along with our existing borrowing availability and access to both debt and equity markets, will be sufficient to meet any working capital and future operating requirements, and capital investment forecasted opportunities.

As of December 31, 2020, $1.022023, $1.95 billion of Eversource's long-term debt, including $450.0 million, $250.0 million, $282.0 million, and $40.2 million for$1.35 billion at Eversource parent NSTAR Electric, PSNH, and Aquarion, respectively, will mature$139.8 million at CL&P, matures within the next 12 months. The current portion of long-term debt on the Eversource balance sheet also includes $31.0 million related to fair value adjustments from our various business combinations that will be amortized within the next 12 months and have no cash flow impact. Eversource, with its strongsolid credit ratings, has several options available in the financial markets to repay or refinance these maturities with the issuance of new long-term debt. Eversource, CL&P, NSTAR Electric and PSNH will reduce their short-term borrowings with operating cash flows or with the issuance of new long-term debt, determined by considering capital requirements and maintenance of Eversource's credit rating and profile.  

We expectCash and Cash Equivalents totaled $53.9 million as of December 31, 2023, compared with $374.6 million as of December 31, 2022.

As a result of the CL&P and Eversource parent long-term debt issuances in January 2024, $139.8 million and $990.9 million, respectively, of current portion of long-term debt were reclassified as Long-Term Debt on CL&P’s and Eversource parent’s balance sheets as of December 31, 2023.

Rate Reduction Bonds: PSNH's RRB payments consist of principal and interest and are paid semi-annually. PSNH paid $43.2 million of RRB principal payments in each of 2023 and 2022, and paid $16.2 million and $17.6 million of interest payments in 2023 and 2022, respectively.

Common Share Issuances and 2022 Equity Distribution Agreement: On May 11, 2022, Eversource entered into an equity distribution agreement pursuant to which it may offer and sell up to $1.2 billion of its common shares from time to time through an “at-the-market” (ATM) equity offering program. In 2023, no shares were issued under this agreement. In 2022, Eversource issued 2,165,671 common shares, which resulted in proceeds of $197.1 million, net of issuance costs. Eversource used the net proceeds received for general corporate purposes.

Cash Flows:  Cash flows from operating activities primarily result from the transmission and distribution of electricity, and the distribution of natural gas and water. Cash flows provided by operating activities totaled $1.65 billion in 2023, compared with $2.40 billion in 2022. Operating cash flows were unfavorably impacted by an increase in regulatory under-recoveries driven primarily by the timing of collections for the CL&P non-bypassable FMCC and other regulatory tracking mechanisms, the timing of cash payments made on our accounts payable, a $26.7 million increase in cash payments to vendors for storm costs, an $11.9 million increase in cost of removal expenditures, and the timing of other working capital items. In 2023, CL&P increased the flow back to customers of net revenues generated by long-term state-approved energy contracts by providing these credits to customers through the non-bypassable FMCC retail rate. The reduction in the CL&P non-bypassable FMCC retail rate decreased the regulatory over-recovery balance and created an under-recovery balance as of December 31, 2023, which resulted in a decrease to amortization expense of $802.3 million in 2023, as compared to 2022, and is presented as a cash outflow in Amortization on the statement of cash

flows. The impacts of regulatory collections are included in both Regulatory Recoveries and Amortization on the statements of cash flows. These unfavorable impacts were partially offset by the timing of cash collections on our accounts receivable, the absence in 2023 of $78.4 million of payments in 2022 related to withheld property taxes at our Massachusetts companies, a decrease of $76.3 million in pension contributions made in 2023 compared to 2022, the absence in 2023 of $72.0 million of customer credits distributed in 2022 at CL&P as a result of the October 2021 settlement agreement and the 2021 storm performance penalty for CL&P’s response to Tropical Storm Isaias, and a $38.7 million increase in operating cash flows due to lower income tax payments.

In 2023, we paid cash dividends of $919.0 million and issued non-cash dividends of $23.4 millionin the form of treasury shares, totaling dividends of $942.4 million, or $2.70 per common share. In 2022, we paid cash dividends of $860.0 million and issued non-cash dividends of $23.1 million in the form of treasury shares, totaling dividends of $883.1 million, or $2.55 per common share. Our quarterly common share dividend payment was $0.675 per share in 2023, as compared to $0.6375 per share in 2022.  On January 31, 2024, our Board of Trustees approved a common share dividend payment of $0.715 per share, payable on March 29, 2024 to shareholders of record as of March 5, 2024.  

Eversource issues treasury shares to satisfy awards under the Company's incentive plans, shares issued under the dividend reinvestment and share purchase plan, and matching contributions under the Eversource 401k Plan.

In 2023, CL&P, NSTAR Electric and PSNH paid $330.4 million, $327.4 million and $112.0 million, respectively, in common stock dividends to Eversource parent.  

Investments in Property, Plant and Equipment on the statements of cash flows do not include amounts incurred on capital projects but not yet paid, cost of removal, AFUDC related to equity funds, and the capitalized and deferred portions of pension and PBOP income/expense.  In 2023, investments for Eversource, CL&P, NSTAR Electric, and PSNH alongwere $4.34 billion, $1.09 billion, $1.38 billion and $605.1 million, respectively. Capital expenditures were primarily for continuing projects to maintain and improve infrastructure and operations, including enhancing reliability to the transmission and distribution systems.

Capital contributions in the offshore wind investments, including the 2023 contribution for the tax equity investment in South Fork Wind, are included in Investments in Unconsolidated Affiliates on the statements of cash flows. Proceeds received from the sale of the uncommitted lease area of $625 million in 2023 and from an October 2023 distribution of $318 million received primarily as a result of being a 50 percent joint owner in the Class B shares of South Fork Wind which was restructured as a tax equity investment, are included in Proceeds from Unconsolidated Affiliates on the statement of cash flows. Proceeds from the October 2023 distribution were used to pay down short-term debt. Proceeds from Unconsolidated Affiliates also includes proceeds received from the liquidation of an equity method investment in a renewable energy investment fund of $147.6 million in 2023.

Contractual Obligations: For information regarding our cash requirements from contractual obligations and payment schedules, see Note 9, "Long-Term Debt," Note 10, "Rate Reduction Bonds and Variable Interest Entities," Note 11A, "Employee Benefits - Pension Benefits and Postretirement Benefits Other Than Pension," Note 13, "Commitments and Contingencies," and Note 14, "Leases," to the financial statements.

EasternOur transmission projects are designed to improve the reliability of the electric grid, meet customer demand for power and increases in electrification of municipal infrastructure, strengthen the electric grid's resilience against extreme weather and other safety and security threats, and enable integration of increasing amounts of clean power generation from renewable sources, such as solar, battery storage, and offshore wind. In Connecticut, Massachusetts Transmission Projects: These projects consist of a portfolio of electric transmission upgrades in southernand New Hampshire, northern Massachusettsour transmission projects include transmission line upgrades, the installation of new transmission interconnection facilities, substations and continuing into the greater Boston metropolitan area, of which 28 upgrades are in Eversource's service territory (two in New Hampshirelines, and 26 in Massachusetts). The two New Hampshire upgrades, including the Merrimack Valley Reliability Project, have been placed in service, and 23 Massachusetts upgrades have been placed in service. On December 17, 2019, the Massachusetts Siting Board issued a favorable decision on the Sudbury-Hudson Reliability Project, the last project requiring such approval. On January 17, 2020, the Town of Sudbury and Protect Sudbury, a community group, appealed the decision to the Massachusetts Supreme Judicial Court. Oral arguments are scheduled for March 1, 2021. The majority of remaining upgrades are under construction and are expected to be placed in service in 2022. We estimate our portion of the investment will be approximately $750 million, of which $525 million has been spent and capitalized through December 31, 2020.transmission substation enhancements.

Southeastern Massachusetts Transmission Projects: These projects consist of a portfolio of electric transmission and substation upgrades in southeastern Massachusetts, including Cape Cod, required to reinforce the Southeastern Massachusetts transmission system and bring the system into compliance with applicable national and regional reliability standards. ISO-NE reassessed the need for projects that had yet to be constructed and reconfirmed the need for the majority of the originally identified reinforcements in July 2020. Twelve upgrades in Eversource's service territory were reconfirmed, and a single upgrade was deemed to no longer be required. Of the twelve upgrades, four require siting approvals from the Massachusetts regulatory agencies, of which one has received approval, two are before the agencies and one, a joint project with National Grid, has yet to be filed. Three substation projects will be permitted locally, three projects are under construction and two projects have been placed in-service. We estimate our portion of the investment will be approximately $175 million, of which $28 million has been spent and capitalized through December 31, 2020.

Hartford-Area Transmission Projects: This portfolio of projects consisted of 27 projects in the Hartford, Connecticut area. In the third quarter of 2020, the final projects were placed in service and as of December 31, 2020, CL&P has spent and capitalized $303 million in costs associated with this portfolio. Additional restoration costs in the first quarter of 2021 will bring the total investment to approximately $304 million.

Seacoast Reliability Project: The Seacoast Reliability Project consisted of a 13-mile, 115kV transmission line within several New Hampshire communities, using a combination of overhead, underground and underwater line designs that helped meet the growing demand for electricity in the Seacoast region. The project was placed in service on May 29, 2020 and resulted in an investment of approximately $124 million.

Ready Path Solution: The Ready Path Solution was chosen in 2020 by ISO-NE as part of the first competitive solicitation for reliability upgrades in New England to meet the energy shortfall that will be created with the retirement of the Mystic Generating Station in Massachusetts in 2024. Our portion of the portfolio consists of installing new equipment at Eversource’s existing North Cambridge Substation with an estimated investment of approximately $14 million. The project is advancing permitting and engineering with construction scheduled to start in 2021.

All project costs are anticipated to be fully recoverable through transmission rates.

Acquisition of Assets of Columbia Gas of Massachusetts: On October 9, 2020, Eversource acquired certain assets and liabilities that comprised NiSource’s natural gas distribution business in Massachusetts, which was previously doing business as CMA, pursuant to an asset purchase agreement (the Agreement) entered into on February 26, 2020 between Eversource and NiSource Inc. (NiSource). The cash purchase price was $1.1 billion, plus a target working capital amount of $69.6 million, which is subject to adjustment to reflect actual working capital as of the closing date that has not yet been finalized. Eversource financed the asset acquisition through a combination of debt and equity issuances in a ratio that was consistent with our consolidated capital structure. The natural gas distribution assets acquired from CMA were assigned to EGMA, an indirect wholly-owned subsidiary of Eversource formed in 2020. The LNG assets acquired from CMA were assigned to Hopkinton LNG Corp. EGMA distributes natural gas to approximately 332,000 residential, commercial and industrial customers with over 5,000 miles of natural gas distribution pipeline across more than 60 communities in Massachusetts, adding to the approximately 303,000 natural gas customers that Eversource already serves in Massachusetts.

The transaction required approval by the DPU, the Maine Public Utilities Commission, the FERC, and the Federal Communications Commission, and review under the Hart-Scott-Rodino Act.

The liabilities assumed by Eversource under the Agreement specifically excluded any liabilities (past or future) arising out of, or related to, the fires and explosions that occurred on September 13, 2018 in Lawrence, Andover and North Andover, Massachusetts related to the delivery of natural gas by CMA, including certain subsequent events, all as described and in the DPU's Order on Scope dated December 23, 2019 (D.P.U. 19-141) (the Greater Lawrence Incident or GLI). The liabilities assumed also excluded any further emergency events prior to the closing of the acquisition related to the restoration and reconstruction with respect to the GLI, including any losses arising out of, or related to, any litigation, demand, cause of action, claim, suit, investigation, proceeding, indemnification agreements or rights. Eversource did not assume any of CMA's or NiSource Inc.'s third party debt obligations or notes payable.

EGMA Rate Settlement Agreement: On October 7, 2020, the DPU approved a rate settlement agreement, which requested approval of the February 26, 2020 asset purchase agreement between Eversource and NiSource, as well as a rate stabilization plan, among other items. The settlement agreement included an authorized regulatory ROE of 9.70 percent as of January 1, 2021, a 53.25 percent equity component of its capital structure, and established rate base equal to $995 million as of the closing on October 9, 2020.

The approved rate stabilization plan includes base distribution rate increases of $13 million on November 1, 2021 and $10 million on November 1, 2022. The settlement agreement includes two rate base resets during an eight-year rate plan, occurring on November 1, 2024 and November 1, 2027. The two rate base resets adjust distribution rates to account for capital additions (including the roll-in of GSEP capital additions), depreciation expense, property taxes, and return on rate base for capital additions placed into service through December 31, 2023, for the first rate base reset occurring on November 1, 2024, and through December 31, 2026, for the second rate base reset occurring on November 1, 2027. Notwithstanding the two distribution rate increases, the two rate base reset provisions, and potential adjustments for qualifying exogenous events, EGMA agreed not to file for an increase or redesign of distribution base rates effective prior to November 1, 2028.

The settlement agreement also permits EGMA to seek recovery of both transaction and integration costs as a result of the asset acquisition after December 31, 2026, subject to DPU review and approval, and subject to certain conditions, such as demonstrating savings resulting from the acquisition.

Offshore Wind Business: OurEversource’s offshore wind business includes 50 percent ownership interests in North East Offshore and Bay State Wind,wind partnerships, which togethercollectively hold PPAs and contracts for the Revolution Wind, South Fork Wind and Sunrise Wind projects, as well as offshore leases issued by BOEM. Ourand a tax equity investment in South Fork Wind. The offshore wind projects are being developed and constructed through a joint and equal partnershippartnerships with Ørsted. This partnership also participates in new procurement opportunities for offshore wind energy in the Northeast U.S.

Eversource has a 50 percent ownership interest in North East Offshore, which holds the Revolution Wind and South Fork Wind projects, as well as a 257 square-mile ocean lease off the coasts of Massachusetts and Rhode Island. Eversource also has a 50 percent ownership interest in Bay State Wind, which holds the Sunrise Wind project. Bay State Wind's separate 300-square-mile ocean lease is located approximately 25 miles south of the coast of Massachusetts adjacent to the North East Offshore area. In aggregate, the Bay State Wind and the North East Offshore ocean lease sites jointly-owned by Eversource and Ørsted could eventually develop at least 4,000 MW of clean, renewable offshore wind energy. As of December 31, 2020,2023 and 2022, Eversource's total equity investment balance in its offshore wind business was $887.1$515.5 million an increase of $237.8 million, as compared to 2019.and $1.95 billion, respectively.

We are preparing our final project designs and advancing the appropriate federal, state and local siting and permitting processes along with ourExpected Sales of Offshore Wind Investments: On May 25, 2023, Eversource announced that it had completed a strategic review of its offshore wind partner, Ørsted, allinvestments and determined that it would pursue the sale of which is competitively sensitive. We currently expect to make investments in ourits offshore wind businessinvestments. On September 7, 2023, Eversource completed the sale of its 50 percent interest in an uncommitted lease area consisting of approximately $300175,000 developable acres located 25 miles off the south coast of Massachusetts to Ørsted for $625 million in an all-cash transaction.

In September of 2023, Eversource made a contribution of $528 million using the proceeds from the lease area sale to $500 million during 2021,invest in a tax equity interest for South Fork Wind. South Fork Wind was restructured as a tax equity investment, with Eversource purchasing 100 percent ownership of a new Class A tax equity membership interest. As a result of this investment, Eversource expects to receive investment tax credits after the turbines are placed in service for South Fork Wind and meet the requirements to qualify for the ITC. These credits will be utilized to reduce Eversource’s federal tax liability or generate tax refunds over the next 24 months. All of South Fork Wind’s twelve turbines are expected to be installed and placed into service by the end of March 2024.

On January 24, 2024, Ørsted signed an agreement with Eversource to acquire Eversource’s 50 percent share of Sunrise Wind. The sale is subject to advancing ourthe successful selection of Sunrise Wind in the ongoing New York fourth solicitation for offshore wind capacity, signing of an OREC contract with NYSERDA, finalization of sale agreements, receipt of final project designsfederal construction permits, and federal, staterelevant regulatory approvals. If Sunrise Wind is not successful in the solicitation, then the existing OREC contract for Sunrise Wind will be cancelled according to the state’s requirements, and local permitting processes.Eversource and Ørsted’s joint venture for Sunrise Wind will remain in place. In that scenario, Ørsted and Eversource would then assess their options in determining the best path forward for Sunrise Wind and its assets, which include the BOEM offshore lease area. If Sunrise Wind’s revised bid is successful in the new solicitation, Sunrise Wind would have 90 days to negotiate a new OREC agreement at the re-bid price. In a successful re-bid, Ørsted would become the sole owner of Sunrise Wind, while Eversource would remain contracted to lead the project’s onshore construction. If Sunrise Wind is successful in the re-bid, Ørsted would pay Eversource 50 percent of the negotiated purchase price upon closing the sale transaction, with the remaining 50 percent paid when onshore construction is completed and certain other milestones are achieved. On January 25, 2024, Eversource and Ørsted submitted a new proposal for Sunrise Wind in the New York fourth offshore wind solicitation.

On February 13, 2024, Eversource announced that it has executed an agreement to sell its existing 50 percent interests in the South Fork Wind and Revolution Wind projects to Global Infrastructure Partners (GIP). As part of this transaction, Eversource expects to receive approximately $1.1 billion of cash proceeds upon closing, which includes the sales value related to the 10 percent energy community ITC adder of approximately $170 million related to Revolution Wind, and to exit these projects while retaining certain cost sharing obligations for the construction of Revolution Wind. The purchase price is subject to future post-closing adjustment payments based on, among other things, the progress, timing and expense of construction at each project. The cost sharing obligations provide that Eversource would share equally with GIP in GIP’s funding obligations for up to approximately $240 million of incremental capital expenditure overruns incurred during the construction phase for the Revolution Wind project, after which GIP’s obligations for any additional capital expenditure overruns would be shared equally by Eversource and Ørsted. Additionally, Eversource’s financial exposure will be adjusted by certain purchase price adjustments to be made following commercial operation of the Revolution Wind project and closing of South Fork as a result of final project economics, which includes Eversource’s obligation to maintain GIP’s internal rate of return for each project as specified in the agreement. Eversource currently expects that South Fork Wind will reach full commercial operation prior to closing of the sale with GIP and Eversource does not expect any material cost sharing or other purchase price adjustment payments for South Fork Wind.

Factors that could result in Eversource’s total net proceeds from the transaction to be lower or higher include Revolution Wind’s eligibility for federal investment tax credits at other than the anticipated 40 percent level; the ultimate cost of construction and extent of cost overruns for Revolution Wind; delays in constructing Revolution Wind, which would impact the economics associated with the purchase price adjustment; and a benefit due to Eversource if there are lower operation costs or higher availability of the projects through the period that is four years following the commercial operation date of the Revolution Wind project.

Closing a transaction with GIP would be subject to customary conditions, including certain regulatory approvals under the Hart Scott Rodino Act and by the New York Public Service Commission and the FERC, as well as other conditions, among which is the completion and execution of the partnership agreements between GIP and Ørsted that will govern GIP’s new ownership interest in those projects following Eversource’s divestiture. Closing of the transaction is currently expected to occur in mid-2024. If closing of the sale is delayed, additional capital contributions made by Eversource would be recovered in the sales price. Under the agreement, Eversource’s existing credit support obligations are expected to roll off for each project around the time that each project completes its expected capital spend.

Impairment: Equity method investments are assessed for impairment when conditions exist as of the balance sheet date that indicate that the fair value of the investment may be less than book value. Eversource continually monitors and evaluates its equity method investments to determine if there are indicators of an other-than-temporary impairment. If the decline in value is considered to be other-than-temporary, the investment is written down to its estimated fair value, which establishes a new cost basis in the investment. Subsequent declines or recoveries after the reporting date are not considered in the impairment recognized. Investments that are other-than-temporarily impaired and written down to their estimated fair value cannot subsequently be written back up for increases in estimated fair value. Impairment evaluations involve a significant degree of judgment and estimation, including identifying circumstances that indicate an impairment may exist at the equity method investment level, selecting discount rates used to determine fair values, and developing an estimate of discounted future cash flows expected from investment operations or the sale of the investment.

In connection with the process to divest its offshore wind business, Eversource identified indicators for impairment in both the second and fourth quarters of 2023. In each impairment assessment, Eversource evaluated its investments and determined that the carrying value of the equity method offshore wind investments exceeded the fair value of the investments and that the decline in fair value was other-than-temporary. The completion of the strategic review in the second quarter of 2023 resulted in Eversource recording a pre-tax other-than-temporary impairment charge of $401 million ($331 million after-tax) to reflect the investment at estimated fair value based on the expected sales price at that time. This established a new cost basis in the investments. Negative developments in the fourth quarter of 2023, including a lower expected sales price, additional projected construction cost increases, and the October 2023 OREC pricing denial for Sunrise Wind, resulted in Eversource conducting an impairment evaluation and recognizing an additional pre-tax other-than-temporary impairment charge of $1.77 billion ($1.62 billion after-tax) and establishing a new cost basis in the investments as of December 31, 2023. The Eversource statement of income reflects a total pre-tax other-than-temporary impairment charge of $2.17 billion ($1.95 billion after-tax) in its offshore wind investments for the year ended 2023.

The impairment evaluations involved judgments in developing the estimates and timing of the future cash flows arising from the expected sales price of Eversource’s 50 percent interest in the wind projects, including expected sales value from investment tax credit adder amounts, less estimated costs to sell, and uncertainties related to the Sunrise Wind re-bid process in New York’s offshore wind solicitation. Additional assumptions in the fourth quarter assessment included revised projected construction costs and estimated project cost overruns, estimated termination costs, salvage values of Sunrise Wind assets, and the value of the tax equity ownership interest. The assumptions used in the discounted cash flow analyses are subject to inherent uncertainties and subjectivity. The use of different assumptions, estimates, or judgments with respect to the estimation of future cash flows could materially change the impairment charges. The impairment evaluations were based on best information available at the impairment assessment dates. New information from events or circumstances arising after the balance sheet date, such as the January 25, 2024 re-bid of Sunrise Wind in the New York solicitation, are not included in the December 31, 2023 impairment evaluation. All significant inputs into the impairment evaluations were Level 3 fair value measurements.

The expected cash flows arising from the anticipated sales are a significant input in the impairment evaluation. In the fourth quarter of 2023, project construction forecasts were updated, and these new forecasts reflected additional expenditures for construction and scheduling related pressures, including the availability and increased cost of installation vessels and supply chain cost increases related to foundation fabrication. In determining the current fair value of the investments, these updated projections exceeded the previously estimated projections for construction expenditures, which resulted in a revised sales price that was significantly lower than the previous bid value. Another significant assumption in the impairment evaluation includes the probability of payment of future cost overruns on the three wind projects through each project's respective commercial operation date, which would not be recovered in the expected sales price. This assumption was based on construction projections updated in the fourth quarter of 2023 exceeding prior estimates. An increase in expected cost overruns could result in a significant impairment in a future period.

Another key assumption in the impairment model of our offshore wind investments was investment tax credit (“ITC”) adders that were included in the Inflation Reduction Act and were a separate part of the sales price value offered by GIP. An ITC adder is an additional 10 percent of credit value for ITC eligible costs and include two distinct qualifications related to either using domestic sourced materials (domestic content) or construction of an onshore substation in a designated community (energy community). Similar to the base ITC of 30 percent of the eligible costs, any ITC adders generated would be used to reduce an owner’s federal tax liability and could be used to receive tax refunds from prior years as well. Management believes there is a high likelihood that the 10 percent energy community ITC adder is realizable, and that ITC adder would amount to approximately $170 million of additional sales value related to Revolution Wind and that it would qualify for the ITC adder after it reaches commercial operation in 2025. Although management believes the ITC adder value is realizable, there is some uncertainty at this time as to whether or not those ITC adders can be achieved, and management continues to evaluate the project’s qualifications and to monitor guidance issued by the United States Treasury Department. A change in the expected value or qualification of ITC adders could result in a significant impairment in a future period.

Another fourth quarter 2023 development included in the impairment evaluation is the key judgment regarding the probability of future cash inflows and outflows associated with the sale or abandonment of the Sunrise Wind project and the expected outcome of the New York fourth offshore wind solicitation in 2024. In June 2023, Sunrise Wind filed a petition with the New York State Public Service Commission for an order authorizing NYSERDA to amend the Sunrise Wind OREC contract to increase the contract price to cover increased costs and inflation. At that time, management expected the contract repricing would be successful given NYSERDA’s public support for pricing adjustments. On October 12, 2023, the New York State Public Service Commission denied this petition. Subsequent to the denial, on November 30, 2023, the general terms of an expedited offshore wind renewable energy solicitation in New York were released. A primary condition for Sunrise Wind to participate in this new solicitation was to agree to terminate its existing OREC agreement. As of December 31, 2023, Eversource and Ørsted were considering whether to submit a new bid for Sunrise Wind, the price at which a new bid would be made, and the probability of success in the new bidding process. The December 31, 2023 impairment evaluation included management’s judgment of the likelihood of possible future scenarios that included the Sunrise Wind project continuing with its existing OREC contract, the project re-bidding and being selected in the new solicitation, the project re-bidding and not being selected, or the project not moving forward. The unfavorable development of the October 2023 denial of the OREC pricing petition, management’s assessment of the likelihood of success in the competitive New York re-bidding process, and the increased costs to build the project, have resulted in management’s assumption that the Sunrise Wind project will ultimately be abandoned, and therefore, no sales value was modeled in the impairment evaluation. Additionally, in the abandonment assumption, management has assumed the loss of contingent sales value associated with any related ITC adders and has estimated future cash outflows for Eversource’s share of cancellation costs required under Sunrise Wind’s supplier contracts, partially offset by expected salvage value and expected cost overruns not incurred in the case of abandonment that are included in the fourth quarter 2023 impairment charge. An increase in expected cancellation costs could result in a significant impairment in a future period.

A summary of the significant estimates and assumptions included in the 2023 impairment charges is as follows:

Management will continue to monitor and evaluate all facts and circumstances in the offshore wind sales process and the impact on its investment balance. Adverse changes in facts and circumstances of estimates and timing of future cash flows and the factors described above could result in the recognition of additional, significant impairment charges that could be material to the financial statements.

The impairment charge was a non-cash charge and did not impact Eversource’s cash position. Eversource will continue to make future cash expenditures for required cash contributions to its offshore wind investments up to the time of disposition of each of the offshore wind projects. Capital contributions are expected until the sales are completed and changes in the timing and amounts of these contributions would be adjusted in the sales prices and therefore not result in an additional impairment charge. Proceeds from the transactions will be used to pay off parent company debt. Eversource’s offshore wind investments do not meet the criteria to qualify for presentation as a discontinued operation.

Our offshore wind projects are subject torequire receipt of federal, state and local approvals necessary to construct and operate the projects. The federal permitting process is governedled by BOEM, and state approvals are required from New York, Rhode Island and Massachusetts. South Fork Wind and Revolution Wind have received all required approvals to start construction. Significant delays in the siting and permitting process resulting from the timeline for obtaining approval from BOEM and the state and local agencies as well as the impact of COVID-19, could adversely impact the timing of these projects'Sunrise Wind’s' in-service dates.date.

Federal Siting and Permitting Process: The South Fork Wind project has commenced the federal siting and permitting process for each of our offshore wind projects commence with the filing of itsa Construction and Operations Plan (COP) application with BOEM. BOEM in 2018. The first major milestone inprovides a review schedule for the project’s COP approval and conducts environmental and technical reviews of the COP. BOEM review process is an issuance of a Notice of Intent to completeissues an Environmental Impact Statement (NOI), which South Fork Wind received in 2018. In August 2020, we received the final review schedule from BOEM regarding South Fork Wind’s COP approval. In January 2021, BOEM released its Draft Environmental Impact Statement (EIS) for the South Fork Wind project, which assessedthat assesses the environmental, social, and economic impacts of constructing the project. Identified impacts were negligibleproject and recommends measures to major adverse impactsminimize impacts. The Final EIS will inform BOEM in deciding whether to marineapprove the project or to approve with modifications and terrestrial archaeological resourcesBOEM will then issue its Record of Decision. BOEM issues its final approval of the COP following the Record of Decision.

Revolution Wind and to historic,Sunrise Wind filed their COP applications with BOEM in March 2020 and non-historic visual resources fromSeptember 2020, respectively. For the Revolution Wind project, construction and operations. TheBOEM released its Draft EIS also analyzed four alternatives to be evaluated as parton September 2, 2022 and its Final EIS on July 17, 2023. On August 21, 2023, BOEM issued its Record of Decision, which concluded BOEM’s environmental review of the process. Eachproject and identified the recommended configuration. Final approval of the identified alternative configurations had a similar level of environmental impacts, and if an alternative configuration was selected, the South ForkRevolution Wind project would still meetwas received on November 20, 2023. For the contractual output underSunrise Wind project, BOEM released its PPA. ADraft EIS on December 16, 2022 and its Final EIS on December 15, 2023. The Record of Decision is expected in the thirdfirst quarter of 20212024 and a final decisionapproval of Sunrise Wind is expected in January 2022.the second quarter of 2024.

Based on BOEM’s final review schedule and final United States Army Corps of Engineers approval, we expect to start construction on South Fork in early 2022. South Fork Wind, isRevolution Wind and Sunrise Wind are each designated as a “Covered Project” pursuant to Title 41 of the Fixing America’s Surface Transportation Act (FAST41) and a Major Infrastructure Project under Section 3(e) of Executive Order 13807, which provides greater federal attention on meeting the project’sprojects’ permitting timelines.

Revolution Wind and Sunrise Wind filed their COP applications with BOEM in March 2020 and September 2020, respectively. Both projects received FAST41 designation in 2020. We are awaiting BOEM to outline its timeline for completing the review of each of the Revolution Wind and Sunrise Wind COPs in an NOI, which we expect to receive in 2021.

State and Local Siting and Permitting ProcessProcess:: South Fork Wind commenced the New York state siting process in 2018. On September 17, 2020, South Fork Wind filed a Joint Proposal in the New York State Article VII siting application. Amongst other things, the Joint Proposal included proposed mitigations to certain environmental, community and construction impacts associated with constructing electrical infrastructure. South Fork Wind was initially joined by PSEG Long Island and several citizens advocacy organizations. On October 9, 2020, the Joint Proposal was signed by the New York Departments of Public Service, Environmental Conservation, Transportation and State as well as the Office of Parks, Recreation and Historic Preservation. Hearings in the state siting process concluded in December 2020 and a decision is expected in mid-2021.

On September 10, 2020, the Town of East Hampton and the East Hampton Town Trustees announced that they had reached an agreement with South Fork Wind to issue the necessary easements and other real estate rights necessary to construct the South Fork Wind project. The Town approved the easements on January 21, 2021 and Trustees approved the lease on January 25, 2021.

State permitting applications in Rhode Island for Revolution Wind and in New York for Sunrise Wind were filed in December 2020. TheOn July 8, 2022, the Rhode Island Energy Facilities Siting Board issued a Final Decision and Order approving the Revolution Wind application was deemed completeproject and granting a license to construct and operate.

On November 17, 2022, the New York Public Service Commission approved an order adopting a Joint Proposal filed by Sunrise Wind and granting a Certificate of Environmental Compatibility and Public Need. On November 18, 2022, Sunrise Wind filed its Phase 1 Environmental Management and Construction Plan (EM&CP) with the New York Public Service Commission, which details the plans on Januarylimited onshore construction activities subject to state and local jurisdiction. On March 27, 2023, Sunrise Wind filed its EM&CP for Phase 2, which covers the remainder of the project components. On June 22, 20212023, Sunrise Wind received approval of the Phase 1 EM&CP. On July 13, 2023, the New York State Public Service Commission approved Sunrise Wind’s notice for authorization to proceed with construction for Phase 1. On December 18, 2023, Sunrise Wind received approval of the Phase 2 EM&CP.

On November 9, 2022, the Towns of Brookhaven and Suffolk County executed the easements and other real estate rights necessary to construct the Sunrise Wind project. On November 28, 2022, the Town of North Kingstown and the preliminary hearingQuonset Development Corporation approved Revolution Wind’s real estate PILOT terms and the personal property PILOT agreement necessary to construct the Revolution Wind project.

Construction Process: South Fork Wind received all required approvals to start construction and the project entered the construction phase in early 2022. All major onshore construction activities, including the project’s underground onshore transmission line and the onshore interconnection facility located in East Hampton, New York are complete. Offshore construction activities began in the fourth quarter of 2022, and installation of the subsea transmission cable, the monopile foundations and offshore substation was completed in 2023. Installation of the project’s 11-megawatt wind turbines continued throughout 2023 and four of South Fork Wind’s twelve turbines were placed into service by January 1, 2024, meeting the project commercial operation date requirements under the power purchase agreement with LIPA. All wind turbines are expected to be installed

For Revolution Wind, on October 31, 2023, the joint venture made its final investment decision to advance to full onshore and offshore construction and installation, and major construction began in the fourth quarter of 2023 upon receipt of all necessary federal, state and local approvals. For Sunrise Wind, once all necessary federal, state and local approvals are received and the joint venture has made its final investment decision, informed in part by the outcome of the New York fourth solicitation, then major construction is expected to begin. Sunrise Wind has started limited onshore construction activities.

FERC Regulatory Matters

FERC ROE Complaints: Four separate complaints were filed at the FERC by combinations of New England state attorneys general, state regulatory commissions, consumer advocates, consumer groups, municipal parties and other parties (collectively, the Complainants). In each of the first three complaints, filed on October 1, 2011, December 27, 2012, and July 31, 2014, respectively, the Complainants challenged the NETOs' base ROE of 11.14 percent that had been utilized since 2005 and sought an order to reduce it prospectively from the date of the final FERC order and for the separate 15-month complaint periods. In the fourth complaint, filed April 29, 2016, the Complainants challenged the NETOs' base ROE billed of 10.57 percent and the maximum ROE for transmission incentive (incentive cap) of 11.74 percent, asserting that these ROEs were unjust and unreasonable.

The ROE originally billed during the period October 1, 2011 (beginning of the first complaint period) through October 15, 2014 consisted of a base ROE of 11.14 percent and incentives up to 13.1 percent. On October 16, 2014, the FERC issued Opinion No. 531-A and set the base ROE at 10.57 percent and the incentive cap at 11.74 percent for the first complaint period. This was also effective for all prospective billings to customers beginning October 16, 2014. This FERC order was vacated on April 14, 2017 by the U.S. Court of Appeals for the D.C. Circuit (the Court).

All amounts associated with the first complaint period have been refunded. Eversource has recorded a reserve of $39.1 million (pre-tax and excluding interest) for the second complaint period as of both December 31, 20202023 and 2019.2022. This reserve represents the difference between the billed rates during the second complaint period and a 10.57 percent base ROE and 11.74 percent incentive cap. The reserve consisted of $21.4 million for CL&P, $14.6 million for NSTAR Electric and $3.1 million for PSNH as of both December 31, 20202023 and 2019.2022.

On October 16, 2018, FERC issued an order on all four complaints describing how it intends to address the issues that were remanded by the Court. FERC proposed a new framework to determine (1) whether an existing ROE is unjust and unreasonable and, if so, (2) how to calculate a replacement ROE. Initial briefs were filed by the NETOs, Complainants and FERC Trial Staff on January 11, 2019 and reply briefs were filed on March 8, 2019. The NETOs' brief was supportive of the overall ROE methodology determined in the October 16, 2018 order provided the FERC does not change the proposed methodology or alter its implementation in a manner that has a material impact on the results.

The FERC order included illustrative calculations for the first complaint using FERC's proposed frameworks with financial data from that complaint. Those illustrative calculations indicated that for the first complaint period, for the NETOs, which FERC concludes are of average financial risk, the preliminary just and reasonable base ROE is 10.41 percent and the preliminary incentive cap on total ROE is 13.08 percent.

If the results of the illustrative calculations were included in a final FERC order for each of the complaint periods, then a 10.41 percent base ROE and a 13.08 percent incentive cap would not have a significant impact on our financial statements for all of the complaint periods. These preliminary calculations are not binding and do not represent what we believe to be the most likely outcome of a final FERC order.

On November 21, 2019, FERC issued Opinion No. 569 affecting the two pending transmission ROE complaints against the Midcontinent ISO (MISO) transmission owners, in which FERC adopted a new methodology for determining base ROEs. Various parties sought rehearing. On December 23, 2019, the NETOs filed supplementary materials in the NETOs' four pending cases to respond to this new methodology because of the uncertainty of the applicability to the NETOs' cases.

On May 21, 2020, the FERC issued its order in Opinion No. 569-A on the rehearing of the MISO transmission owners' cases, in which FERC again changed its methodology for determining the MISO transmission owners' base ROEs. Various parties appealed the MISO transmission owners' opinion. On November 19, 2020, the FERC issued Opinion No. 569-B denying rehearing of Opinion No. 569-A and reaffirmed the methodology previously adopted in Opinion No. 569-A. The new methodology differs significantly from the methodology proposed by FERC in its October 16, 2018 order to determine the NETOs' base ROEs in its four pending cases. FERC Opinion Nos. 569-A and 569-B were appealed to the Court. On August 9, 2022, the Court issued its decision vacating MISO ROE FERC Opinion Nos. 569, 569-A and 569-B and remanded to FERC to reopen the proceedings. The Court found that FERC’s development of the new return methodology was arbitrary and capricious due to FERC’s failure to offer a reasonable explanation for its decision to reintroduce the risk-premium financial model in its new methodology for calculating a just and reasonable return. At this time, Eversource cannot predict how and when FERC will address the Court’s findings on the remand of the MISO FERC opinions or any potential associated impact on the NETOs’ four pending ROE complaint cases.

Given the significant uncertainty regarding the applicability of the FERC opinions in the MISO transmission owners'owners’ two complaint cases to the NETOs'NETOs’ pending four complaint cases, Eversource concluded that there is no reasonable basis for a change to the reserve or recognized ROEs for any of the complaint periods at this time. As well, Eversource cannot reasonably estimate a range of any gain or loss for any of the four complaint proceedings at this time.

Eversource, CL&P, NSTAR Electric and PSNH currently record revenues at the 10.57 percent base ROE and incentive cap at 11.74 percent established in the October 16, 2014 FERC order.
41



A change of 10 basis points to the base ROE used to establish the reserves would impact Eversource’s after-tax earnings by an average of approximately $3 million for each of the four 15-month complaint periods. FromProspectively from the date of a final FERC order implementing a new base ROE, based off of estimated 2023 rate base, a change of 10 basis points to the base ROE would impact Eversource’s 2021future annual after-tax earnings by approximately $5$5.5 million or $0.01 per share, per year, and will increase slightly over time as we continue to invest in our transmission infrastructure.

FERC Notice of Inquiry on ROE: On March 21, 2019, FERC issued a Notice of Inquiry (NOI) seeking comments from all stakeholders on FERC's policies for evaluating ROEs for electric public utilities, and interstate natural gas and oil pipelines. On June 26, 2019, the NETOs jointly filed comments supporting the methodology established in the FERC’s October 16, 2018 order with minor enhancements going forward. The NETOs jointly filed reply comments in the FERC ROE NOI on July 26, 2019. On May 12, 2020, the NETOs filed supplemental comments in the NOI ROE docket. At this time, Eversource cannot predict how this proceeding will affect its transmission ROEs.

38


FERC Notice of Inquiry and Proposed Rulemaking on Transmission Incentives: On March 21, 2019, FERC issued an NOI seeking comments on FERC's policies for implementing electric transmission incentives. On June 26, 2019, Eversource filed comments requesting that FERC retain policies that have been effective in encouraging new transmission investment and remain flexible enough to attract investment in new and emerging transmission technologies. Eversource filed reply comments on August 26, 2019. On March 20, 2020, FERC issued a Notice of Proposed Rulemaking (NOPR) on transmission incentives. The NOPR intends to revise FERC’s electric transmission incentive policies to reflect competing uses of transmission due to generation resource mix, technological innovation and shifts in load patterns. FERC proposes to grant transmission incentives based on measurable project economics and reliability benefits to consumers rather than its current project risks and challenges framework.  On July 1, 2020, Eversource filed comments generally supporting the NOPR.

On April 15, 2021, FERC issued a Supplemental NOPR that proposes to eliminate the existing 50 basis point return on equity for utilities that have been participating in a regional transmission organization (RTO ROE incentive) for more than three years. On June 25, 2021, the NETOs jointly filed comments strongly opposing FERC’s proposal. On July 26, 2021, the NETOs filed Supplemental NOPR reply comments responding to various parties advocating for the elimination of the RTO Adder. If FERC issues a final order eliminating the RTO ROE incentive as proposed in the Supplemental NOPR, the estimated annual impact (using 2023 estimated rate base) on Eversource's after-tax earnings is approximately $19.5 million. The Supplemental NOPR contemplates an effective date 30 days from the final order.

At this time, Eversource cannot predict howthe ultimate outcome of these proceedings, will affectincluding possible appellate review, and the resulting impact on its transmission incentives.

FERC Transmission Transparency Settlement: On December 28, 2015, FERC initiated a proceeding to review the NETOs' regional and local transmission formula rates due to a lack of transparency, finding that the formula rates appeared to lack sufficient details to determine how costs are derived and recovered in rates. Parties engaged in further settlement negotiations and reached an agreement in principle on October 22, 2019. On June 15, 2020, the NETOs filed an uncontested Settlement Agreement with FERC, which was signed by all six New England state regulatory commissions, New England States Committee on Electricity, New England Municipals and all the NETOs. On December 28, 2020, the FERC issued an order approving the Settlement Agreement, which establishes annual formula rate transparency procedures effective June 15, 2021, implements a new regional and local rate structure effective January 1, 2022, and contains a rate moratorium through December 31, 2024.

Regulatory Developments and Rate Matters

Electric, Natural Gas and Water Utility Base DistributionRetail Tariff Rates: Each Eversource utility subsidiary is subject to the regulatory jurisdiction of the state in which it operates:  CL&P, Yankee Gas and Aquarion operate in Connecticut and are subject to PURA regulation; NSTAR Electric, NSTAR Gas, EGMA and Aquarion operate in Massachusetts and are subject to DPU regulation; and PSNH and Aquarion operate in New Hampshire and are subject to NHPUC regulation.  The regulated companies' distribution rates are set by their respective state regulatory commissions, and their tariffs include mechanisms for periodically adjusting their rates for the recovery of specific incurred costs.  

Base Distribution Rates:In Connecticut, electric, and natural gas and water utilities serving more than seventy-five thousand customers are required to file a distribution rate case or for PURA to initiate a rate review, within four years of the last rate case. PURA can elect to convene a general rate hearing at an interval of less than four years unless prohibited from doing so by an agency decision or other law. CL&P's and Yankee Gas' base distribution rates were each established in 2018 PURA-approved rate case settlement agreements. Aquarion is not required to initiateOn October 27, 2021, PURA approved a settlement agreement for CL&P that included a current base distribution rate freeze until no earlier than January 1, 2024. The approval of the settlement agreement satisfied the Connecticut statute of rate review withrequirements that requires electric utilities to file a distribution rate case within four years of the PURA on a set schedule. Aquarion rates were established in a 2013 PURA-approvedlast rate case.

On March 15, 2023, PURA issued a final decision that rejected Aquarion Water Company of Connecticut’s (AWC-CT) application with PURA to amend its existing rate schedules. AWC-CT filed an appeal on the decision and on May 25, 2023, the State of Connecticut Superior Court granted a permanent stay of certain orders affecting base rates, which will keep existing rates in place until the appeal is completed. For further information, see "Regulatory Developments and Rate Matters - Connecticut," below.

In Massachusetts, electric distribution companies are required to file at least one distribution rate caseschedules every five years, and natural gas local distribution companies to file at least one distribution rate caseschedules every 10 years, and those companies are limited to one settlement agreement in any 10-year period. NSTAR Electric's base distribution rates were established in a 2017November 2022 DPU-approved rate case. NSTAR Gas' base distribution rates were established in an October 2020 DPU-approved rate case. EGMA's base distribution rates were established in an October 2020 DPU-approved rate settlement agreement. Aquarion is not required to initiate a rate review with the DPU. AquarionAquarion’s base distribution rates were established in a 2018 DPU-approved rate case.

In New Hampshire, PSNH's base distribution rates were established in a December 2020 NHPUC-approved rate case settlement agreement. AquarionAquarion's base distribution rates were established in a 2013July 2022 NHPUC-approved rate case further revised in 2016. On December 18, 2020, Aquarion filed an applicationsettlement agreement, with the NHPUC for a permanent increase in base rates,single step adjustment approved on January 19, 2023. Rates were effective FebruaryMarch 1, 2021.2023.

Electric, Natural Gas and Water Utility Retail Rates: The Eversource electric distribution companies obtain and resell power to retail customers who choose not to buy energy from a competitive energy supplier.  CL&P, NSTAR Electric and PSNH enter into full requirements energy supply procurement contracts for its customers that choose to purchase power from the electric distribution company (standard offer, basic service or default energy service, respectively). The natural gas distribution companies procure natural gas for firm and seasonal customers. These energy supply and natural gas supply procurement costs are recovered from customers in energy supply rates that are approved by the respective state regulatory commission.  The rates are reset periodically (every six months for electric residential customers) and are fully reconciled to their costs.  New energy supply rates for residential customers are established effective July 1st at CL&P and NSTAR Electric and effective August 1st at PSNH. Each electric and natural gas distribution company fully recovers its energy supply costs through approved regulatory rate mechanisms on a timely basis and, therefore, such costs have no impact on earnings. Increases or decreases in energy supply retail rates result in corresponding fluctuations in both energy supply procurement revenues and purchased power or purchased natural gas expenses on the statements of income.

The electric and natural gas distribution companies also recover certain other costs in retail rates on a fully reconciling basis through regulatory commission-approved cost tracking mechanisms and, therefore, recovery of these costs has no impact on earnings. Costs recovered through cost tracking mechanisms include, among others, electric retail transmission charges, energy efficiency program costs, electric retail transmission charges, electric restructuring and stranded costscost recovery revenues (including securitized RRB charges), certain capital tracking mechanisms for infrastructure improvements, and additionally for ourthe Massachusetts companies,utilities, pension and PBOP benefits, and net metering for distributed generation.generation, and solar-related programs. The reconciliation filings compare the total actual costs allowed to revenue requirements related to these services and the difference between the costs incurred (or the rate recovery allowed) and the actual costs allowed is deferred and included, to be either recovered or refunded, in future customer rates.  These cost tracking mechanisms also include certain incentives earned, return on rate base and on capital tracking mechanisms, and carrying charges that are billed in rates to customers, which do impact earnings.

COVID-19 Regulatory Dockets: In Connecticut, PURA opened a docket to address COVID-19 developments, including issuing orders on March 18, 2020, April 29, 2020 and May 15, 2020 that authorized electric, natural gas and water utilities to establish a regulatory asset for COVID-19 uncollectible customer receivable expenses and costs associated with the related orders.  PURA’s April 29, 2020 order, as supplemented on May 15, 2020, also allowed the inclusion of working capital costs in the regulatory asset, and authorized electric, natural gas and water utilities to establish a payment plan program designed to assist any customer who requests financial assistance during the COVID-19 pandemic. On July 10, 2020, PURA denied a request from a coalition of large industrial customers to reduce or suspend certain electric and natural gas charges during the COVID-19 pandemic.

In Massachusetts, on July 31, 2020, the DPU approved and adopted a coalition of electric, natural gas and water utilities’ comprehensive Customer Assistance Plan involving extended payment plans and waiver of late fees, extended plans under available arrearage management plans (AMPs), and continuation of the Shut-Off Moratorium. On September 3, 2020, the DPU approved the 2020 small commercial arrearage forgiveness program (AFP) proposed by the electric and natural gas distribution companies. In its interim order dated December 31, 2020, the DPU established certain cost tracking and data reporting requirements for the distribution companies and will allow each company to record, defer, and track incremental cost areas, subject to the DPU’s final determination of the ratemaking treatment in D.P.U. 20-58 and D.P.U. 20-91. In D.P.U. 20-91, the DPU will adjudicate the contested cost-recovery provisions identified in the Ratemaking Proposal and consider proposals to expand alternative customer bill payment options. The distribution companies’ Ratemaking Proposal for COVID-19 financial-related impacts includes recovery requests for each of the following five cost categories: (1) cash working capital; (2) arrearage forgiveness; (3) bad debt; (4) COVID-19 O&M expenses; and (5) waived fees.

In New Hampshire, on October 5, 2020, the NHPUC approved an agreement governing collections and disconnection activities, deposit activities, flexible payment plans, and special arrangements for income-qualified customers for all New Hampshire utilities including Eversource’s electric and water utilities. The terms of that agreement continue through at least April 2021. Also, on August 18, 2020, the NHPUC Staff recommended that utilities in New Hampshire be permitted to create a regulatory asset for waived fees and incremental bad debt related to the COVID-19 pandemic. On November 13, 2020, the NHPUC Staff revised its recommendation arguing that waived fees should not be included in any regulatory asset related to the COVID-19 pandemic. The New Hampshire utilities disputed that recommendation on December 4, 2020, and on December 16, 2020, the NHPUC Staff renewed its November 13, 2020 recommendation. The NHPUC has yet to act on that recommendation.

Storm Event:

On August 4, 2020, Tropical Storm Isaias caused catastrophic damage to our electric distribution system, which resulted in significant amounts and durations of customer outages, primarily in Connecticut. In terms of customer outages, this storm was one of the worst in CL&P’s history. PURA has opened an investigation into CL&P's response to Tropical Storm Isaias.  PURA will also investigate the prudence of costs incurred by CL&P to restore service as part of its response.  CL&P is fully participating in PURA’s investigations and believes that these storm restoration costs were prudently incurred and meet the criteria for cost recovery.  As a result, management does not expect the storm costs to have a material impact on the results of operations of Eversource or CL&P.

Based on current estimates, the storm resulted in deferred storm restoration costs on our balance sheets of approximately $228 million at CL&P and $245 million at Eversource as of December 31, 2020. The estimated cost of restoration will change as additional cost information becomes available, final storm costs are deferred or capitalized, and post-storm restoration work is completed. The majority of incremental storm costs relate to third-party vendors that are external field crews needed to restore power and address municipal priorities. CL&P’s current estimate of total storm costs includes its projection of the cost of such vendors, but that estimate will change as CL&P receives and examines all storm related invoices.

Connecticut:

CL&P Storm Investigation:Performance Based Rate Making: On August 7,May 26, 2021, in accordance with an October 2020 Connecticut law, PURA opened a proceeding to begin to evaluate and eventually implement performance based regulation (PBR) for electric distribution companies. PURA is conducting the proceeding in two phases. On January 25, 2023, PURA staff issued a proposal outlining a suggested portfolio of PBR elements for further exploration and potential implementation in the second phase of the proceeding. On April 26, 2023, PURA issued a noticefinal decision on the first phase and identified various objectives to guide PBR development and evaluate adoption of a PBR framework. The decision commenced Phase 2 by initiating three reopener dockets focused on revenue adjustment mechanisms, performance metrics and integrated distribution system planning with final decisions expected in 2025.

On November 16, 2023, PURA issued a straw proposal in the first reopener that it had opened a docketfocused on revenue adjustment mechanisms. The proposal outlines potential additions and reforms to investigate the preparation forcurrent revenue adjustment mechanisms, such as multi-year rate plans, earnings sharing mechanisms and responsethe revenue decoupling mechanism, which would apply at the time of CL&P’s next distribution rate case. The straw proposal is not authoritative and technical sessions are continuing prior to Tropical Storm Isaias by Connecticut utilities, including CL&P. Hearings were completed in January 2021 and a final decisiondecision. PURA is currently expected to issue a straw proposal in the second reopener focusing on April 28, 2021. Ifperformance incentive mechanisms (PIMs) in the April 28, 2021 final decision concludes thatfirst quarter of 2024.The three reopener dockets continue to progress through the Phase 2 process. We continue to monitor developments in this proceeding, and at this time, we cannot predict the ultimate outcome of this proceeding and the resulting impact to CL&P failed to comply with applicable storm performance standards, then a separate proceeding will be initiated on May 7, 2021 to examine if and what amount of any civil penalty could potentially be imposed on CL&P, with a final decision currently anticipated on July 14, 2021.&P.

CL&P Rate SuspensionStorm Filing:: On December 22, 2023, CL&P initiated a docket seeking a prudency review of approximately $634 million of catastrophic storm costs for twenty-four weather events from January 1, 2018 to December 31, 2021. In the filing, CL&P requested PURA establish a rate to collect $50 million annually from customers from the date of the final decision in this proceeding. This rate would be effective until the next distribution rate case and would replenish the under-collected storm reserve and reduce future carrying charges for customers.

CL&P Advanced Metering Infrastructure Filing: On July 31, 2020, PURA temporarily suspended its June 26, 2020 approval of certain delivery rate components effective July 1, 2020, and ordered CL&P submitted to restore rates to those in effect asPURA its proposed $512 million Advanced Metering Infrastructure investment and implementation plan. On August 17, 2021, PURA issued a Notice of June 30, 2020 in order to allow PURA time to reexamine the rates to ensure thatRequest for an Amended EDC Advanced Metering Infrastructure Proposal. On November 8, 2021, CL&P is not over-collecting revenuessubmitted an Amended Proposal in response to this request with an updated schedule for the short-term. Rates were adjusted effective August 1, 2020. PURA indicated that this was due toyears 2022 through 2028, which included additional information as required by PURA. As required, the convergenceplan includes a full deployment of advanced metering functionality and a numbercomposite business case in support of recent events, including the COVID-19 crisis and its corresponding effect on customer energy usage, as well as the warmer than normal weather in July.Advanced Metering Infrastructure plan. On December 2, 2020,January 3, 2024, PURA issued a final decision inregarding CL&P’s Advanced Metering Infrastructure investment and implementation plan, which it adjustedCL&P most recently estimated at $766.4 million for capital costs and one-time operating expenses. In CL&P’s view, the timingfinal decision does not provide a reasonable path for cost recovery and delays implementation by a year. In addition, the final decision modifies the prudence standard for recovery of costs expended on the project, improperly linking recovery to outcomes not known at the outset of the annual rate adjustmentsproject. On January 18, 2024, CL&P submitted a motion for reconsideration to PURA asking that the Revenue Decoupling Mechanism Charge,agency modify these aspects of the Transmission Adjustment Clause charge, the Non-Bypassable Federally Mandated Congestion Charge, and the Electric System Improvements Tracker so that these rates take effect on May 1st of each year, as opposed to the current process of adjusting rates each January 1 and July 1. The final decision also modified the calculation of carrying charges and shifted the timing of recovery to rely on more actual versus forecasted information, among other changes.decision.

40Termination of Park City Wind’s Power Purchase Agreement with CL&P: On October 2, 2023, Park City Wind LLC and CL&P signed an agreement to terminate the Park City Wind offshore wind generation PPA, at the request of Park City Wind LLC. The termination agreement was effective on October 13, 2023, the date of PURA approval. In October 2023, Park City Wind LLC paid a termination payment of $12.9 million to CL&P resulting from the termination of the PPA, which CL&P will return to customers.


Aquarion Water Company of Connecticut Distribution Rate Case: On August 29, 2022, Aquarion Water Company of Connecticut (AWC-CT) filed an application with PURA to amend its existing rate schedules to address an operating revenue deficiency. AWC-CT’s rate application requested approval of rate increases of $27.5 million, an additional $13.6 million, and an additional $8.8 million, effective March 15, 2023, 2024, and 2025, respectively. On March 15, 2023, PURA issued a final decision that rejected this request. In this decision, PURA ordered a base distribution rate decrease of $2.0 million effective March 15, 2023. The temporary suspensiondecision allows an authorized regulatory ROE of 8.70 percent. On March 30, 2023, AWC-CT filed an appeal on the decision and requested a stay of the decision with the State of Connecticut Superior Court. On April 5, 2023, the Court temporarily granted AWC-CT’s request to stay and on May 25, 2023 granted a permanent stay of certain orders affecting base rates, has resultedwhich will keep existing rates in place until the appeal is completed. The stay included the condition that AWC-CT place any revenue received from customers above the rates and amounts authorized in the March 15, 2023 decision in a current period under-recovery of costs, which results in an increase to our regulatory assets, with no impactseparate, interest bearing account until further order.

NSTAR Electric’s PBR mechanism allows for an annual adjustment to base distribution rates for inflation, exogenous events and future capital additions based on a historical five-year average of total capital additions. NSTAR Electric submitted its first annual PBR Adjustment filing on September 15, 2023 and on December 26, 2023, the original requestDPU approved a $104.9 million increase to base distribution rates effective January 1, 2024. The base distribution rate increase was comprised of $38.0a $50.6 million inflation-based adjustment and a $54.3 million K-bar adjustment for capital additions based on the difference between the historical five-year average of total capital additions and the base capital revenue requirement.

NSTAR Electric’s Electric Sector Modernization Plan (ESMP) Filing: Massachusetts state law requires the electric distribution companies to file a comprehensive distribution system plan by January 29, 2024, to proactively upgrade the distribution system (and, where applicable, the associated transmission system) to: (i) improve grid reliability, communications and resiliency; (ii) enable increased, timely adoption of renewable energy and distributed energy resources; (iii) promote energy storage and electrification technologies necessary to decarbonize the environment and economy; (iv) prepare for future climate-driven impacts on the transmission and distribution systems; (v) accommodate increased transportation electrification, increased building electrification and other potential future demands on distribution and, where applicable, the transmission system; and (vi) minimize or mitigate impacts on Massachusetts ratepayers, thereby helping the state realize its statewide greenhouse gas emissions limits and sublimits under the law. On January 29, 2024, NSTAR Electric filed its ESMP with the DPU. NSTAR Electric’s plan meets these requirements by providing a comprehensive view of all the investments required to build a safer, more reliable, more resilient electric distribution system taking into account the needs of environmental justice communities. For the five-year period from 2025 through 2029, the proposed incremental capital investment is $608 million and the incremental expense amount is $211 million. NSTAR Gas' 2019 plant additions are allowed recovery beginning on November 1, 2021.  Thus, the reduced revenue requirement reflects the removal of this recovery, among other adjustments. The DPU also approved NSTAR Gas' proposal to continue its ongoing Gas System Enhancement Program (GSEP),must approve, approve with modification, or reject the inclusion of GSEP investments since 2015 into base rates, and the implementation of a 10-year performance-based ratemaking plan, which includes an inflation-based adjustment mechanism to annual base distribution rates. The decision allows an authorized regulatory ROE of 9.9 percent on a capital structure including 54.77 percent equity. The decision also approves a geothermal pilot program. The impact of the rate case decision resulted in a pre-tax charge to earnings in 2020 of $2.7 million at NSTAR Gas, primarily due to certain plant-related disallowances.ESMP filing within seven months after filing.

SaleTermination of Water System:SouthCoast Wind’s Power Purchase Agreements with NSTAR Electric: On August 28, 2023, SouthCoast Wind Energy LLC and NSTAR Electric signed agreements to terminate three SouthCoast Wind offshore wind generation PPAs, at the request of SouthCoast Wind Energy LLC. The termination agreements were effective on September 29, 2023, the date of DPU approval. In October 2023, SouthCoast Wind Energy, LLC paid a termination payment totaling $32.5 million to NSTAR Electric resulting from the termination of the PPAs, which NSTAR Electric will return to customers.

PSNH Distribution Rates:Pole Acquisition Approval: On June 27, 2019,November 18, 2022, the NHPUC issued a decision that approved a settlementproposed purchase agreement that was reached bybetween PSNH theand Consolidated Communications, in which, PSNH would acquire both jointly-owned and solely-owned poles and pole assets. The NHPUC Staff, the Office of the Consumer Advocate, and another settling party, to implement a temporary annual base distribution rate increase of $28.3 million. Although new rates were implemented on August 1, 2019 to customers, the provisions of the temporary base distribution rate increase were effective July 1, 2019. The settlement agreement also permittedauthorized PSNH to recover approximately $68.5certain expenses associated with the operation and maintenance of the transferred poles, pole inspections, and vegetation management expenses through a new cost recovery mechanism, the PPAM, subject to consummation of the purchase agreement. The purchase agreement was finalized on May 1, 2023 for a purchase price of $23.3 million. Upon consummation of the purchase agreement, PSNH established a regulatory asset of $16.9 million for operation and maintenance expenses and vegetation management expenses associated with the purchased poles incurred from February 10, 2021 through April 30, 2023 that PSNH is authorized to collect through the PPAM regulatory tracking mechanism. The establishment of the PPAM regulatory asset resulted in unrecovered storm costs over a five-year period beginning Augustpre-tax benefit recorded in Amortization expense on the PSNH statement of income in 2023.

PSNH Energy Efficiency Plan: On February 24, 2022, a state law was enacted that directed that the joint utility energy efficiency plan and programming framework in effect on January 1, 2019, with debt carrying charges, which is included in2021 be utilized going forward, including utility performance incentive payments, lost base revenue calculations, and Evaluation, Measurement, and Verification process. Additionally, the temporarylaw established a process for future plan proposals, including the 2024 through 2026 triennial plan, and includes a mechanism for future rate increase.increases based on the consumer price index.

On May 28, 2019, PSNH filed an application with the NHPUC for a permanent increase in base distribution rates of approximately $70 million, effective July 1, 2020, which included the temporary rate increase request. Temporary rates remained in effect with a reconciliation of permanent rates retroactive to July 1, 2019 once permanent rates were set.

On December 15, 2020,November 30, 2023, the NHPUC approved an October 9, 2020 settlement agreementa three-year joint utility energy efficiency plan for 2024 through 2026, of which, $158 million is the PSNH program budget over the next three years. Additionally, on permanent rates between PSNH and all parties to the proceeding. The NHPUC approved a permanent rate increase of $45.0 million effective January 1, 2021, inclusive of the temporary rate increase referenced above. PSNH was also permitted three step increases, effective January 1, 2021, August 1, 2021, and August 1, 2022, to reflect plant additions in calendar years 2019, 2020 and 2021, respectively. On December 23, 2020,22, 2023, the NHPUC approved the first step adjustmentannual LBR rate for 2019 plant in service2024, allowing PSNH to recover aapproximately $14 million in revenue requirementthat would have been collected if not for the implementation of $10.6 million, subject to reconciliation after completion of an audit, effective January 1, 2021. The settlement agreement also established an authorized regulatory ROE of 9.3 percent with a 54.4 percent common equity ratio in PSNH’s capital structure and provided for a new tracker to recover regulatory assessments, vegetation management costs, property tax costs, and lost distribution revenue attributable to net metering. In addition, base distribution rates were adjusted to reflect the refund of EDIT from the Tax Cuts and Jobs Act of 2017.energy efficiency measures.

The settlement agreement allowed for the effect of the permanent rate increase to be extended back to the temporary rate period. In lieu of a customer rate increase for this recoupment of revenue, the NHPUC directed a portion of the total EDIT regulatory liability to offset bill impacts to customers. The impact of the settlement agreement resulted in an after-tax benefit to earnings in 2020 of $11.0 million at Eversource ($7.2 million at PSNH), due primarily to the reconciliation of permanent rates back to the temporary rate period resulting in a reduction of the EDIT regulatory liability, which reduced Income Tax Expense on the statement of income, and the allowed recovery of previously expensed costs. The earnings impact was partially offset by the negative impact from the over-refunding of the change in the 2018 federal corporate income tax rate as a result of the Tax Cuts and Jobs Act of 2017 that was reflected in temporary rates, which reduced Operating Revenues on the statement of income.

PSNH Generation Asset Divestiture-Related Costs: On May 15, 2020, the NHPUC Audit Staff issued a final report on the audit of PSNH’s generation asset divestiture-related costs and resulting securitized and stranded costs. The findings in the audit report as well as other aspects of the divestiture process were further investigated by NHPUC Staff through the discovery phase, which was completed in July 2020. On September 30, 2020, PSNH filed a settlement agreement on the generation asset divestiture-related costs with the NHPUC Audit Staff. The settlement agreement resolved all issues with respect to PSNH’s divestiture of its generating assets and the recovery of $12.0 million of divestiture-related costs incurred above the $635.7 million amount previously securitized. On December 17, 2020, the NHPUC approved the additional $12.0 million proposed in the settlement agreement to be recovered over a one-year period through the SCRC rate beginning February 1, 2021.

Legislative and Policy Matters

Federal: Connecticut:On March 27, 2020, President Trump signed the $2.2 trillion bipartisan Coronavirus Aid, Relief,June 29, 2023, Connecticut enacted Public Act No. 23-102 (Substitute Senate Bill No. 7) (the Act) that encompasses 40 sections. The Act prohibits recovery in retail rates of certain costs incurred by utilities, including costs for consultants and Economic Security (CARES) Act. Among other provisions, the CARES Act providesoutside counsel for loansrate cases, membership dues, and other benefits to small and large businesses, expanded unemployment insurance, direct payments to those with wages middle-income and below, new appropriations funding for health care and other priorities, and tax changes like deferrals of employer payroll tax liabilities coupled with an employee retention tax credit and rollbacks of Tax Cuts and Jobs Act of 2017 limitations on net operating losses and certain business interest limitation. For the year ended December 31, 2020, we have recorded a tax liability of approximately $39 million related to the deferral of employer payroll tax liability provision. Fifty percentlobbying. None of the deferral of employer payroll tax liability must be paid by December 31, 2021 and the remaining amount by December 31, 2022.

The Act also makes prospective adjustments to the “Consolidated Appropriations Act, 2021.” The Housetiming and procedures used in the retail rate setting process, including (1) requiring additional procedural steps to be satisfied for proposed settlements of Representatives and Senate previously passedcases; (2) increasing the billdeadline to issue a final decision on an application from a water company to amend base rates from 200 days to 270 days; (3) authorizing PURA to elect to evaluate if rates should be reduced on an interim basis if a utility earns an ROE that exceeds its authorized ROE by 50 basis points over a rolling 12-month period ending with overwhelming support. The legislation includes tax extenders as part of Division EE, the “Taxpayer Certainty and Disaster Tax Relief Act of 2020.” The provisions within the law include the extensiontwo most recent consecutive financial quarters (instead of the Investment Tax Credit (ITC) for solarcurrent standard of 100 basis points); and (4) authorizing PURA to elect to convene a general rate hearing at 26 percent for facilitiesan interval of less than four years unless prohibited from doing so by an agency decision or other law. The Act is prospective, not retroactive and therefore, does not change obligations or rate provisions established by settlements implemented prior to the construction of which begins through the end of 2022, at 22 percent for facilities the construction of which begins in 2023, and postponement of the date after which solar facilities placed in service receive only a 10 percent ITC to December 31, 2025, the extension of the ITC at 30 percent (with no phase-down) to offshore wind if construction begins by December 31, 2025 (qualifying offshore wind includes facilities located in the inland navigable waters or in the coastal waters of the U.S.), and the extension and expansion of the CARES Act employee retention tax credit for the period from January 1, 2021 through June 30, 2021, including increasing the credit rate from 50 percent to 70 percent of qualified wages, and increasing the per-employee creditable wages limit from $10,000 per year to $10,000 for each quarter. The tax credit provision impacts to Eversource are still being evaluated but are a significant positive development for the Company and provides the opportunity to generate additional tax credits in its renewable energy projects when the projects become operational.Act.

Massachusetts: On January 28, 2021,The Act also prohibits CL&P’s electric system improvements (ESI) capital tracking mechanism from being reauthorized in the Massachusetts Legislature approved legislation which permitsnext general distribution proceeding. The ESI will therefore remain in place until base distribution rates are adjusted in CL&P’s next general distribution rate proceeding. The Act also excludes storms and other emergencies affecting 70 percent or more of an electric distribution company’s customers from the 2020 law requiring credits for residential customers who are without power for 96 or natural gas distribution companies to assist Massachusetts municipalities in responding to the risks of climate change by owning solar facilities equal to up to 10 percent of the total installed solar generating capacity in Massachusetts as of July 31, 2020. Such facilities may be paired with energy storage where feasible to do so. This legislation is anticipated to allow each of Eversource’s Massachusetts operating companies to own up to approximately 280 MWs of solar generating facilities in addition to the 70 MWs previously constructed at NSTAR Electric.more consecutive hours.

Connecticut: On October 8, 2020, Connecticut enactedLastly, the Act was amended by Public Act 20-5No. 23-204 (House Bill Number 7006), September Special Session (the Act).

Critical Accounting Policies

The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and, at times, difficult, subjective or complex judgments. Changes in these estimates, assumptions and judgments, in and of themselves, could materially impact our financial position, results of operations or cash flows. Our management discusses with the Audit Committee of our Board of Trustees significant matters relating to critical accounting policies. Our critical accounting policies are discussed below. See the combined notes to our financial statements for further information concerning the accounting policies, estimates and assumptions used in the preparation of our financial statements.  

Regulatory Accounting:  Our regulated companies are subject to rate regulation that is based on cost recovery and meets the criteria for application of accounting guidance for rate-regulated operations, which considers the effect of regulation on the timing of the recognition of certain revenues and expenses. The regulated companies' financial statements reflect the effects of the rate-making process. The rates charged to the customers of our regulated companies are designed to collect each company's costs to provide service, plus a return on investment.

We believe that the operations of each of our regulated companies currently satisfy the criteria for application of regulatory accounting. If events or circumstances should change in a future period so that those criteria are no longer satisfied, we would be required to eliminate any associated regulatory assets and liabilities and the impact would be recognized in the statement of income and may result in a material adverse effect on results of operations and financial condition.

The application of accounting guidance for rate-regulated enterprises results in recording regulatory assets and liabilities. Regulatory assets represent the deferral of incurred costs that are probable of future recovery in customer rates. Regulatory assets are amortized as the incurred costs are recovered through customer rates. In some cases, we record regulatory assets before approval for recovery has been received from the applicable regulatory commission. We must use judgment to conclude that costs deferred as regulatory assets are probable of future recovery. We base our conclusion on certain factors, including, but not limited to, regulatory precedent.

Regulatory liabilities represent either revenues received from customers to fund expected costs that have not yet been incurred or probable future refunds to customers. We make judgments regarding the future outcome of regulatory proceedings that involve potential future refund to customers and record liabilities for these loss contingencies when probable and reasonably estimable based upon available information. Regulatory liabilities are recorded at the best estimate, or at a low end of the range of possible loss. The amount recorded may differ from when the uncertainty is resolved. Such differences could have a significant impact on our financial statements.

We continually assess whether the regulatory assets and liabilities continue to meet the criteria for probable future recovery or refund. This assessment includes consideration of recent orders issued by regulatory commissions, the passage of new legislation, historical regulatory treatment for similar costs in each of our jurisdictions, discussions with legal counsel, the status of any appeals of regulatory decisions, and changes in applicable regulatory and political environments. We believe that we will continue to be able to defer and recover prudently incurred costs, including additional storm costs, based on the legal and regulatory framework.

We use judgment when recording regulatory assets and liabilities; however, regulatory commissions can reach different conclusions about the recovery of costs, and those conclusions could have a material impact on our financial statements. The ultimate outcome of regulatory rate proceedings could have a significant effect on our ability to recover costs or earn an adequate return. Established rates are also often subject to subsequent prudency reviews by state regulators, whereby various portions of rates could be adjusted, subject to refund or disallowed. Storm restoration and pre-staging costs are subject to prudency reviews from our regulators. We have $1.75 billion of deferred storm costs that either have yet to be filed with the applicable regulatory commission, are pending regulatory approval, or are subject to prudency review as of December 31, 2023. Tropical Storm Isaias resulted in deferred storm restoration costs of approximately $232 million at CL&P as of December 31, 2023. While it is possible that some amount of the Tropical Storm Isaias costs may be disallowed by PURA, any such amount cannot be estimated at this time. We believe that our storm restoration costs were prudently incurred, meet the criteria for cost recovery and are probable of recovery.

45


We believe it is probable that each of theour regulated companies will recover its respective investments in long-lived assets and the regulatory assets that have been recorded. If we determine that we can no longer apply the accounting guidance applicable to rate-regulated enterprises, or that we cannot conclude it is probable that costs will be recovered from customers in future rates, the applicable costs would be charged to net income in the period in which the determination is made.

Pension, SERP and PBOP:  We sponsor Pension, SERP and PBOP Plans to provide retirement benefits to our employees.  Plan assets and the benefit obligation are presented on a net basis and we recognize the overfunded or underfunded status of the plans as an asset or liability on the balance sheet. These amounts are remeasured annually using a December 31st measurement date. For each of these plans, several significant assumptions are used to determine the projected benefit obligation, funded status and net periodic benefit cost.expense/income. These assumptions include the expected long-term rate of return on plan assets, discount rate, compensation/progression rate and mortality and retirement assumptions.  We evaluate these assumptions at least annually and adjust them as necessary.  Changes in these assumptions could have a material impact on our financial position, results of operations or cash flows.

Expected Long-Term Rate of Return on Plan Assets Assumption:  In developing the expected long-term rate of return, we consider historical and expected returns, as well as input from our consultants.  Our expected long-term rate of return on assets is based on assumptions regarding target asset allocations and corresponding expected rates of return for each asset class.  We routinely review the actual asset allocations and periodically rebalance the investments to the targeted asset allocations.  For the year ended December 31, 2020,2023, our expected long-term rate-of-return assumption used to determine our pension and PBOP expense was 8.25 percent for the Eversource Service plansPension and 7 percent for the AquarionPBOP plans.  For the forecasted 20212024 pension and PBOP expense, an expected long-term rate of return of 8.25 percent for the Eversource Service plansPension and 7 percent for the AquarionPBOP plans will be used reflecting our target asset allocations.

Discount Rate Assumptions:  Payment obligations related to the Pension, SERP and PBOP Plans are discounted at interest rates applicable to the expected timing of each plan's cash flows.  The discount rate that was utilized in determining the pension, SERP and PBOP obligations was based on a yield-curve approach.  This approach utilizes a population of bonds with an average rating of AA based on bond ratings by Moody's, S&P and Fitch, and uses bonds with above median yields within that population.  As of December 31, 2020,2023, the discount rates used to determine the funded status were within a range of 2.44.9 percent to 2.75.0 percent for the Pension and SERP Plans, and within a range of 2.55.0 percent to 2.65.2 percent for the PBOP Plans.  As of December 31, 2019,2022, the discount rates used were within a range of 3.05.1 percent to 3.45.2 percent for the Pension and SERP Plans, and within a range of 3.2 percent to 3.35.2 percent for the PBOP Plans.  The decrease in the discount rates used to calculate the funded status resulted in an increase to the Pension and SERP Plans’ projected benefit obligation of $98.9 million and an increase to the PBOP Plans' liabilityprojected benefit obligation of $603.0$12.0 million and $68.3 million, respectively, as of December 31, 2020.2023.  

The Company uses the spot rate methodology for the service and interest cost components of Pension, SERP and PBOP expense because it provides a relatively precise measurement by matching projected cash flows to the corresponding spot rates on the yield curve.  The discount rates used to estimate the 20202023 expense were within a range of 2.64.9 percent to 3.55.3 percent for the Pension and SERP Plans, and within a range of 2.75.1 percent to 3.65.4 percent for the PBOP Plans.  

Mortality Assumptions:  Assumptions as to mortality of the participants in our Pension, SERP and PBOP Plans are a key estimate in measuring the expected payments a participant may receive over their lifetime and the corresponding plan liability we need to record. The mortality assumption is composed of a base table that represents the current expectation of life expectancy of the population adjusted by an improvement scale that attempts to anticipate future improvements in life expectancy. In 2020, a revised scale for2023, our mortality assumption utilized the Society of Actuaries base mortality table was released,tables (Pri-2012), adjusted to reflect Eversource’s own mortality experience, and we utilized it in our measurements.projected generationally using the MP-2021 improvement scale.

Compensation/Progression Rate Assumptions:  This assumption reflects the expected long-term salary growth rate, including consideration of the levels of increases built into collective bargaining agreements, and impacts the estimated benefits that Pension and SERP Plan participants will receive in the future.  As of December 31, 20202023 and 2019,2022, the compensation/progression rates used to determine the funded status were within a range of 3.5 percent to 44.0 percent.  

Health Care Cost Assumptions: The Eversource Service PBOP Plan is not subject to health care cost trends. As of December 31, 2020,2023, for the Aquarion PBOP Plan, the health care trend rate used to determine the funded status for pre-65 retirees is 6.36.75 percent, with an ultimate rate of 5 percent in 2023,2031, and for post-65 retirees, the health care trend rate and ultimate rate is 3.5 percent.

Actuarial Determination of ExpenseGains and Losses::  Pension, SERP and PBOP expense is determined by our actuaries and consists of service cost and prior service cost, interest cost based on the discounting of the obligations, and amortization of actuarial gains and losses, offset by the expected return on plan assets.  Actuarial gains and losses represent the amortization of differences between actuarial assumptions and actual information or updated assumptions. Pre-taxUnamortized actuarial gains or losses arising at the December 31st measurement date are primarily from differences in actual investment performance compared to our expected return and changes in the discount rate assumption. The Eversource Service Pension and PBOP Plans use the corridor approach to determine the amount of gain or loss to amortize into net periodic benefit expense/income. The corridor approach defers all actuarial gains and losses arising at remeasurement and the net unrecognized actuarial gain or loss balance is amortized as a component of expense forif, as of the Pension and SERP Plans was $56.9 million, $63.7 million and $39.6 million forbeginning of the years ended December 31, 2020, 2019 and 2018, respectively.year, that net gain or loss exceeds 10 percent of the greater of the market value of the plan’s assets or the projected benefit obligation. The amount of net unrecognized actuarial gain or loss in excess of the 10 percent corridor is amortized to expense over the estimated average future employee service period. For the Eversource Service Pension Plan, the net actuarial gain or loss is amortized as a component of expense over the estimated average future employee service period of seven years. For the Eversource Service PBOP Plans,Plan, the net unrecognized actuarial gain or loss was within the 10 percent corridor and therefore there was net periodic PBOP incomeno amortization to expense during 2023.

A decrease in the discount rate used to determine our pension funded status would increase our projected benefit obligation at December 31st, resulting in a higher unamortized actuarial loss to be recognized in future years’ pension expense, subject to exceeding the 10 percent corridor. A decrease in the discount rate at December 31st would also result in a decrease in the interest cost component and an increase in the service cost component of $51.6 million, $41.5 million and $45.0 million for the years ended December 31, 2020, 2019 and 2018, respectively.  subsequent year’s benefit plan expense.

The calculated expected return on plan assets is determined by applying the assumed long-term rate of return to the Pension and PBOP Plan asset balances. This calculated expected return is compared to the actual return or loss on plan assets at the end of each year to determine the investment gains or losses to be immediately reflected in unamortized actuarial gains and losses.  An underperformance of our pension plan investment returns relative to the expected returns would increase our pension liability at December 31st, resulting in a higher unamortized actuarial loss to be recognized in future years’ pension expense, subject to exceeding the 10 percent corridor, and a lower expected return on assets component of pension expense in future years’ pension expense.

Net Periodic Benefit Expense/Income: Pension, SERP and PBOP expense/income is determined by our actuaries and consists of service cost and prior service cost/credit, interest cost based on the discounting of the obligations, amortization of actuarial gains and losses, and the expected return on plan assets. For the Pension and SERP Plans, pre-tax net periodic benefit income was $108.4 million and $181.6 million for the years ended December 31, 2023 and 2022, respectively, and there was pre-tax net periodic benefit expense of $23.6 million for the year ended December 31, 2021.  For the PBOP Plans, pre-tax net periodic benefit income was $57.3 million, $79.8 million and $60.5 million for the years ended December 31, 2023, 2022 and 2021, respectively.  

The change in pension, SERP and PBOP expense/income arising from the annual remeasurement does not fully impact earnings. Our Massachusetts utilities recover qualified pension and PBOP expenses related to their distribution operations through a rate reconciling mechanism that fully tracks the change in net pension and PBOP expenses each year, therefore the change in their pension and PBOP expense does not impact earnings. Our electric transmission companies' rates provide for an annual true-up of estimated to actual costs, which include pension expenses, therefore the change in their pension expense does not impact earnings. Any differences between the fixed level of PBOP expense included in our formula rate and the PBOP expense calculated in accordance with authoritative accounting guidance is accumulated as a regulatory asset or liability, and is expected, over time, to be recovered from or returned to customers. Additionally, the portion of our pension and PBOP expense that relates to company labor devoted to capital projects is capitalized on the balance sheet instead of being charged to expense.

Forecasted ExpensesExpense/Income and Expected Contributions:  We estimate that expensenet periodic benefit income in 20212024 for the Pension and SERP Plans will be approximately $28$90 million and income in 2021 for the PBOP Plans will be approximately $58$65 million. The decrease in pension income from 2023 to 2024 is driven primarily by higher amortization of actuarial loss due to unrecognized actuarial loss arising in 2023, partially offset by the absence in 2024 of a 2023 SERP settlement charge and a decrease in the interest cost component due to a lower discount rate. The increase in PBOP income from 2023 to 2024 is driven primarily by favorable expected return on assets due to a higher asset balance and a decrease in the interest cost component due to a lower discount rate. For the PBOP Plans, there is no amortization of actuarial loss in 2024. Pension, SERP and PBOP expenseexpense/income for subsequent years will depend on future investment performance, changes in future discount rates and other assumptions, and various other factors related to the populations participating in the plans.

Our policy is to fund the Pension Plans annually in an amount at least equal to the amount that will satisfy all federal funding requirements.

Goodwill:  We recorded goodwill on our balance sheet associated with previous mergers and acquisitions, all of which totaled $4.45$4.53 billion as of December 31, 2020.2023. We have identified our reporting units for purposes of allocating and testing goodwill as Electric Distribution, Electric Transmission, Natural Gas Distribution and Water Distribution.  Electric Distribution and Electric Transmission reporting units include carrying values for the respective components of CL&P, NSTAR Electric and PSNH.  The Natural Gas Distribution reporting unit includes the carrying values of NSTAR Gas, Yankee Gas and EGMA. We recorded $42 million of goodwillarising from the acquisition of CMA on October 9, 2020. The Water Distribution reporting unit includes the Aquarion water utility businesses.  As of December 31, 2020,2023, goodwill was allocated to the reporting units as follows: $2.54 billion to Electric Distribution, $577 million to Electric Transmission, $441$451 million to Natural Gas Distribution and $884$961 million to Water Distribution.

We are required to test goodwill balances for impairment at least annually by considering the fair values of the reporting units, which requires us to use estimates and judgments. Additionally, we monitor all relevant events and circumstances during the year to determine if an interim impairment test is required. We have selected October 1st of each year as the annual goodwill impairment test date. Goodwill impairment is deemed to exist if the carrying amount of a reporting unit exceeds its estimated fair value. If goodwill were deemed to be impaired, it would be written down in the current period to the extent of the impairment.

In assessing goodwill for impairment, an entity is permitted to first assess qualitatively whether it is more likely than not that goodwill impairment exists as of the annual impairment test date. A quantitative impairment test is required only if it is concluded that it is more likely than not that a reporting unit’s fair value is less than its carrying amount.

We performed an impairment testassessment of goodwill as of October 1, 20202023 for the Electric Distribution, Electric Transmission, Natural Gas Distribution and Water Distribution reporting units. ThisOur qualitative assessment included an evaluation required the consideration of severalmultiple factors that impact the fair value of the reporting units, including general, macroeconomic and market conditions, and entity-specific assumptions that affect the future cash flows of the reporting units. Key considerations include discount rates, utility sector market performance and merger transaction multiples, the Company's share price and credit ratings, analyst reports, financial performance, cost and risk factors, internal estimates and projections of future cash flows and net income.  income, long-term strategy, the timing and outcome of rate cases, and recent regulatory and legislative proceedings.

The 20202023 goodwill impairment assessment resulted in a conclusion that goodwill is not impaired and no reporting unit is at risk of a goodwill impairment. Theimpaired. We believe that the fair value of the reporting units was substantially in excess of carrying value. Adverse regulatory actions, changes in the regulatory and political environment, or changes in significant assumptions could potentially result in future goodwill impairment indicators.

Long-Lived Assets: Impairment evaluations of long-lived assets, including property, plant and equipment and other assets, involve a significant degree of estimation and judgment, including identifying circumstances that indicate an impairment may exist. ImpairmentAn impairment analysis is required when events or changes in circumstances indicate that the carrying value of a long-lived asset may not be recoverable. Indicators of potential impairment include a deteriorating business climate, unfavorable regulatory action, decline in value that is other than temporary in nature, plans to dispose of a long-lived asset significantly before the end of its useful life, and accumulation of costs that are in excess of amounts allowed for recovery. The review of long-lived assets for impairment utilizes significant assumptions about operating strategies and external developments, including assessment of current and projected market conditions that can impact future cash flows.

Impairment of Northern Pass Transmission:  Northern Pass was Eversource's planned 1,090 MW HVDC transmission line that would have interconnected from the Québec-New Hampshire border to Franklin, New Hampshire and an associated alternating current radial transmission line between Franklin and Deerfield, New Hampshire.  As If indicators are present for a result oflong-lived asset or asset group, a final decision received on July 19, 2019 from the New Hampshire Supreme Court, whereby the court denied Northern Pass’ appeal and affirmed the NHSEC’s denial of Northern Pass’ siting application on NPT, Eversource concluded that construction of NPT was no longer probable and that there was no constructive path forward for the project. In 2019, Eversource terminated the project and permanently abandoned any further development. 

Based on the conclusion that the construction of Northern Pass was no longer probable, Eversource recorded an impairment charge in 2019 for allcomparison of the project costs associated with Northern Pass, which were primarily engineering design, siting, permitting and legal costs, along with appropriate allowances for funds usedundiscounted expected future cash flows to the carrying value is performed. No impairments occurred during construction, and recognized a receivable for certain cost reimbursement agreements. Additionally, Eversource recorded an impairment charge associated with the land acquired to construct Northern Pass in order to recognize the land at its estimated fair value based on assessed values and transaction costs. In total, this resulted in a pre-tax impairment charge of $239.6 million within Operating Income on the statement of income for the year ended December 31, 2019, and was reflected in the Electric Transmission segment. The after-tax impact of the impairment charge was $204.4 million, or $0.64 per share, after giving effect to the estimated fair value of the related land, reimbursement agreements, and the impact of expected income tax benefits associated with the impairment charge. As a result of the decision to terminate the NPT project and permanently abandon any further development, Eversource does not expect any future cash expenditures associated with this project.2023.

Equity Method Investments: Investments in affiliates where we have the ability to exercise significant influence, but not control, over an investee are initially recognized as an equity method investment at cost. Any differences between the cost of an investment and the amount of underlying equity in net assets of an investee are considered basis differences and are determined based upon the estimated fair values of the investee's identifiable assets and liabilities. For our offshore wind equity method investment, basis differences are related to intangible assets for PPAs that will be amortized over the term of the PPAs, and equity method goodwill that are not amortized. Capitalized interest associated with our offshore wind equity method investment is included in the investment balance.

44


Equity method investments are assessed for impairment when conditions exist as of the balance sheet date that indicate that the fair value of the investment ismay be less than book value. Eversource continually monitors and evaluates its equity method investments to determine if there are indicators of an other-than-temporary impairment. If the decline in value is considered to be other-than-temporary, the investment is written down to its estimated fair value, which establishes a new cost basis in the investment. Subsequent declines or recoveries after the reporting date are not considered in the impairment recognized. Investments that are other-than-temporarily impaired and written down to their estimated fair value cannot subsequently be written back up for increases in estimated fair value. Impairment evaluations involve a significant degree of judgment and estimation, including identifying circumstances that indicate an impairment may exist at the equity method investment level, selecting discount rates used to determine fair values, and developing an estimate of undiscounteddiscounted future cash flows.flows expected from investment operations or the sale of the investment.

In 2020,connection with the process to divest its offshore wind business, Eversource recorded an other-than-temporaryidentified indicators for impairment in both the second and fourth quarters of $2.8 million within Other Income, Net2023. In each impairment assessment, Eversource evaluated its investments and determined that the carrying value of the equity method offshore wind investments exceeded the fair value of the investments and that the decline was other-than-temporary. The impairment evaluations involved judgments in developing the estimate and timing of future cash flows, including key judgments in determining the most likely outcome of the projects, the likelihood of realization of investment tax credit adders, and the likelihood of future spending amounts and cost overruns, as well as potential cancellation costs and salvage values of Sunrise Wind assets. The assumptions used in the discounted cash flow analyses are subject to inherent uncertainties and subjectivity. The use of different assumptions, estimates, or judgments with respect to the estimation of future cash flows could materially change the impairment charges. The impairment evaluations were based on best information available at the statement of income, related to a write-off of an investment within a renewable energy fund.impairment assessment date.

In 2018, Eversource recorded an other-than-temporary impairmentManagement will continue to monitor and evaluate all facts and circumstances in the offshore wind sales process and the impact on its investment balance. Adverse changes in facts and circumstances of $32.9 million within Other Income, Net on our statementestimates and timing of income, related to Access Northeast, an equity method investment. Eversource identified a September 2018 non-Eversource natural gas series of explosions in eastern Massachusetts, compounded by an adverse legislative environment, as negative evidence that indicated potential impairment of our investment in Access Northeast. In 2018, management determined that the future cash flows and the factors described above could result in the recognition of the Access Northeast project were uncertainadditional, significant impairment charges and could no longer be reasonably estimated and thatmaterial to the book value of ourfinancial statements.

On April 1, 2019, pursuant to a provision in the partnership agreement jointly entered into by Eversource, Enbridge, Inc. and National Grid plc, through Algonquin Gas Transmission, LLC, the Access Northeast project was terminated.investments carrying value.

Income Taxes: Income tax expense is estimated for each of the jurisdictions in which we operate and is recorded each quarter using an estimated annualized effective tax rate. This process to record income tax expense involves estimating current and deferred income tax expense or benefit and the impact of temporary differences resulting from differing treatment of items for financial reporting and income tax return reporting purposes. Such differences are the result of timing of the deduction for expenses, as well as any impact of permanent differences, non-tax deductible expenses, or other items that directly impact income tax expense as a result of regulatory activity (flow-through items). The temporary differences and flow-through items result in deferred tax assets and liabilities that are included in the balance sheets.

48


We also account for uncertainty in income taxes, which applies to all income tax positions previously filed in a tax return and income tax positions expected to be taken in a future tax return that have been reflected on our balance sheets. The determination of whether a tax position meets the recognition threshold under applicable accounting guidance is based on facts and circumstances available to us.

PursuantThe interpretation of tax laws and associated regulations involves uncertainty since tax authorities may interpret the laws differently. Ultimate resolution or clarification of income tax matters may result in favorable or unfavorable impacts to net income and cash flows, and adjustments to tax-related assets and liabilities could be material.

Significant management judgment is required in determining the provision for income taxes, primarily due to the Tax Cutsuncertainty related to tax positions taken, as well as deferred tax assets and Jobs Actliabilities and valuation allowances. We evaluate the probability of 2017, Eversource had remeasured its existingrealizing deferred federaltax assets by reviewing a forecast of future taxable income and our intent and ability to implement tax balancesplanning strategies, if necessary, to reflectrealize deferred tax assets. We also assess negative evidence, such as the decrease inexpiration of historical operating loss or tax credit carryforwards, that could indicate the U.S. federal corporate incomeinability to realize the deferred tax rate from 35 percentassets. Valuation allowances are provided to 21 percent. The remeasurement resulted in provisional regulated excess accumulatedreduce deferred income tax (excess ADIT or EDIT) liabilitiesassets to the amount that will benefit our customersmore likely than not be realized in future periods. As of December 31, 2020, these EDIT liabilities were estimatedThis requires management to be approximately $2.78 billionmake judgments and were included in regulatory liabilities onestimates regarding the balance sheet. Eversource's regulated companies are in the process of, or will be, refunding the EDIT liabilities to customers based on orders issued by applicable state regulatory commissions.

Actual income taxes could vary from estimated amounts due to the ADIT liabilities.future impacts of various items, including future changes in income tax laws, not realizing expected tax planning strategy amounts, as well as results of audits and examinations of filed tax returns by taxing authorities.

Accounting for Environmental Reserves:  Environmental reserves are accrued when assessments indicate it is probable that a liability has been incurred and an amount can be reasonably estimated. Increases to estimates of environmental liabilities could have an adverse impact on earnings. We estimate these liabilities based on findings through various phases of the assessment, considering the most likely action plan from a variety of available remediation options (ranging from no action required to full site remediation and long-term monitoring), current site information from our site assessments, remediation estimates from third party engineering and remediation contractors, and our prior experience in remediating contaminated sites.  If a most likely action plan cannot yet be determined, we estimate the liability based on the low end of a range of possible action plans. A significant portion of our environmental sites and reserve amounts relate to former MGP sites that were operated several decades ago and manufactured natural gas from coal and other processes, which resulted in certain by-products remaining in the environment that may pose a potential risk to human health and the environment, for which we may have potential liability.  Estimates are based on the expected remediation plan. Our estimates are subject to revision in future periods based on actual costs or new information from other sources, including the level of contamination at the site, the extent of our responsibility or the extent of remediation required, recently enacted laws and regulations or a change in cost estimates.  

Fair Value Measurements:  We follow fair value measurement guidance that defines fair value as the price that would be received for the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price).  We have applied this guidance to our Company's derivative contracts that are not elected or designated as "normal purchasespurchases” or normal sales" (normal),“normal sales,” to marketable securities held in trusts, and to our investments in our Pension and PBOP Plans. Fair value measurements are also incorporated into the accounting for goodwill, long-lived assets, equity method investments, and AROs, and in the valuation of the acquisition of CMA in 2020.business combinations and asset acquisitions. The fair value measurement guidance was also applied in estimating the fair value of preferred stock, long-term debt and RRBs.

Changes in fair value of our derivative contracts are recorded as Regulatory Assets or Liabilities, as we recover the costs of these contracts in rates charged to customers.  These valuations are sensitive to the prices of energy and energy-related products in future years for which markets have not yet developed and assumptions are made.

We use quoted market prices when available to determine the fair value of financial instruments.  When quoted prices in active markets for the same or similar instruments are not available, we value derivative contracts using models that incorporate both observable and unobservable inputs.  Significant unobservable inputs utilized in the models include energy and energy-related product prices for future years for long-dated derivative contracts and market volatilities.  Discounted cash flow valuations incorporate estimates of premiums or discounts, reflecting risk-adjusted profit that would be required by a market participant to arrive at an exit price, using available historical market transaction information. Valuations of derivative contracts also reflect our estimates of nonperformance risk, including credit risk.

Weather, fluctuations in energy supply costs,rates, conservation measures (including utility-sponsored energy efficiency programs), and economic conditions affect customer energy usage and water consumption. Industrial sales volumes are less sensitive to temperature variations than residential and commercial sales volumes. In our service territories, weather impacts both electric and water sales volumes during the summer and both electric and natural gas sales volumes during the winter; however, natural gas sales volumes are more sensitive to temperature variations than electric sales volumes. Customer heating or cooling usage may not directly correlate with historical levels or with the level of degree-days that occur.

Fluctuations in retail electric sales volumes at PSNH impact earnings ("Traditional" in the table above). For CL&P, NSTAR Electric, NSTAR Gas, EGMA, Yankee Gas, and our Connecticut water distribution business, fluctuations in retail sales volumes do not materially impact earnings due to their respective regulatory commission-approved distribution revenue decoupling mechanisms ("Decoupled" in the table above). These distribution revenues are decoupled from their customer sales volumes, which breaks the relationship between sales volumes and revenues recognized.

Electric and Natural Gas Distribution Revenues:
Base Distribution Revenues:
Base electric distribution revenues increased $97.5$36.6 million in 2020, as compared to 2019, due primarily to the impact of CL&P's base distribution rate increases effective May 1, 2020 and May 1, 2019, which include recovery of storm costs and certain other items that do not impact earnings, the NSTAR Electrica base distribution rate increase at NSTAR Electric effective January 1, 2020, and the impact of the PSNH temporary base distribution rate increase effective July 1, 2019, which includes recovery of storm costs and certain other items that do not impact earnings.

The increase in total electric distribution revenues was partially offset by the impact of the December 2020 PSNH settlement agreement driven by the negative impact from the over-refunding of the change in the 2018 federal corporate income tax rate as a result of the Tax Cuts and Jobs Act of 2017 that was reflected in temporary rates.2023.

Base natural gas distribution revenues increased $34.3$18.5 million in 2020, as compared to 2019, due primarily to base distribution rate increases at Yankee Gas effective JanuaryNovember 1, 20202023 and November 1, 2022 at NSTAR Gas and effective November 1, 2020.2022 at EGMA.

Tracked Distribution Revenues: Tracked distribution revenues consist of certain costs that are recovered from customers in retail rates through regulatory commission-approved cost tracking mechanisms and therefore, recovery of these costs has no impact on earnings. However, tracked revenues doRevenues from certain of these cost tracking mechanisms also include certain incentives earned, return on rate base and on capital tracking mechanisms, and carrying charges that are billed in rates to customers, which do impact earnings. Costs recovered through cost tracking mechanisms include, among others, energy supply and natural gas supply procurement and other energy-related costs, electric retail transmission charges, energy efficiency program costs, electric restructuring and stranded cost recovery revenues (including securitized RRB charges), certain capital tracking mechanisms for infrastructure improvements, and additionally for the Massachusetts utilities, pension and PBOP benefits, and net metering for distributed generation.generation, and solar-related programs. Tracked revenues also include wholesale market sales transactions, such as sales of energy and energy-related products into the ISO-NE wholesale electricity market, sales of natural gas to third party marketers, and the sale of RECs to various counterparties.

Customers have the choice to purchase electricity from each Eversource electric utility or from a competitive third party supplier. For customers who have contracted separately with these competitive suppliers, revenue is not recorded for the sale of the electricity commodity, as the utility is acting as an agent on behalf of the third party supplier. For customers that choose to purchase electric generation from CL&P, NSTAR Electric or PSNH, each purchases power on behalf of, and is permitted to recover the related energy supply cost without mark-up from, its customers, and records offsetting amounts in revenues and purchased power related to this energy supply procurement. CL&P, NSTAR Electric and PSNH each remain as the distribution service provider for all customers and charge a regulated rate for distribution delivery service recorded in revenues. Certain eligible natural gas customers may elect to purchase natural gas from each Eversource natural gas utility or may contract separately with a
gas supply operator. Revenue is not recorded for the sale of the natural gas commodity to customers who have contracted separately with these
operators, only the delivery to a customer, as the utility is acting as an agent on behalf of the gas supply operator.

Tracked distribution revenues increased/(decreased) in 2020,2023, as compared to 2019,2022, due primarily to the following:

The decreaseincrease in energy supply procurement within electric distribution was driven primarily by lowerhigher average prices, partially offset by higherlower average supply-related sales volumesvolumes. The decrease in 2020,energy supply procurement within natural gas distribution was driven by lower average prices and lower average supply-related sales volumes. Fluctuations in retail transmission revenues are driven by the recovery of the costs of our wholesale transmission business, such as compared to 2019. those billed by ISO-NE and Local and Regional Network Service charges. For further information, see "Purchased Power, Purchased Natural Gas and Transmission" expense below.

The increasedecrease in CL&P’s FMCC revenues was driven by a decrease in the retail Non-Bypassable Federally Mandated Congestion Charge (NBFMCC) rate, which reflects the impact of returning net benefits of higher wholesale market sales received in the ISO-NE market for long-term state approved energy contracts at CL&P, FMCC regulatory tracking mechanismwhich are then credited back to customers through the retail NBFMCC rate. CL&P’s average NBFMCC rate in effect from January 1, 2022 through April 30, 2022 was $0.01423 per kWh and from May 1 through August 31, 2022 was $0.01251 per kWh. As a result of the CL&P RAM proceeding in Docket No. 22-01-03, CL&P reduced the average NBFMCC rate effective September 1, 2022 from $0.01251 per kWh to $0.00000 per kWh. As part of a November 2022 rate relief plan, CL&P further reduced the average NBFMCC rate effective January 1, 2023 to a credit of $0.01524 per kWh. These rate reductions returned to customers the net revenues generated by long-term state-approved energy contracts with the Millstone and Seabrook nuclear power plants. The average NBFMCC rate changed to $0.00000 per kWh effective July 1, 2023. As a result of the increase2023 CL&P RAM decision, the average NBFMCC rate changed to $0.00293 per kWh effective September 1, 2023.

The decrease in electric distribution wholesale market sales revenue within electric distribution was due primarily to lower average electricity market prices received for wholesale sales at CL&P, NSTAR Electric and PSNH. ISO-NE average market prices received for CL&P’s wholesale sales decreased to an average price of $36.60 per MWh in 2023, as compared to $82.88 per MWh in 2022, driven primarily by lower natural gas prices in New England. Volumes sold into the newmarket were primarily from the sale of output generated by the Millstone PPA and Seabrook PPA that CL&P entered into by CL&P in 2019, as required by regulation. Beginning in the fourth quarter of 2019, CL&P sells the energy purchased from Millstone Nuclear Power Station (Millstone)and Seabrook into the wholesale market and uses the proceeds from the energy sales to offset a portion of the contract costs. The net costs under the contract aresales or net cost amount is refunded to, or recovered from, customers in the non-bypassable component of the CL&P FMCC rate.

The addition of EGMA increased total operating revenues at the natural gas distribution segment by $154.8 million.

Electric Transmission Revenues:  Electric transmission revenues increased $147.1$107.2 million in 2020, as compared to 2019, due primarily to a higher transmission rate base as a result of our continued investment in our transmission infrastructure and a higher benefit from the annual billing and cost reconciliation filing with FERC.infrastructure.

Other Revenues and Eliminations: Other revenues primarily include the revenues of Eversource's service company, most of which are eliminated in consolidation. Eliminations are also primarily related to the Eversource electric transmission revenues that are derived from ISO-NE regional transmission charges to the distribution businesses of CL&P, NSTAR Electric and PSNH that recover the costs of the wholesale transmission business.business in rates charged to their customers.

required by regulation, and transmission costs. These electric and natural gas supply procurement costs, other energy-related costs, and
transmission costs are recovered from customers in rates through commission-approved cost tracking mechanisms, which have no impact on
earnings (tracked costs). The variance in Purchased Power, FuelPurchased Natural Gas and Transmission expense decreased in 2020,2023, as compared to 2019,2022, is due primarily to the following:

The increasevariance in purchased power expenseenergy supply procurement costs is offset in Operating Revenues (tracked energy supply procurement revenues). The decrease in other electric distributions costs was primarily the result of a decrease in long-term renewable contract costs and lower net metering costs at the electric distribution business in 2020 as compared to 2019, was driven primarily by the impact of energy purchases from the new Millstone PPA and higher average supply-related sales volumes,NSTAR Electric, partially offset by lower average prices. The decrease in natural gas supplyhigher long-term contractual energy-related costs at ourCL&P that are recovered in the non-bypassable component of the FMCC mechanism, and by higher net metering costs at PSNH.

Total natural gas costs decreased due primarily to lower average prices and lower average salespurchased supply volumes, partially offset by an increase in the addition of EGMA natural gas supply costs as a result of the CMA asset acquisition of $58.8 million.retail cost deferral.

The decrease in transmission costs in 2020, as compared to 2019, was primarily the result of a decrease in the retail transmission cost deferral, which reflects the actual costscost of transmission service compared to estimated amounts billed to customers. This wascustomers and a decrease in costs billed by ISO-NE that support regional grid investments. These decreases were partially offset by an increase in Local Network Service charges, which reflect the cost of transmission service provided by Eversource over our local transmission network, and an increase in costs billed by ISO-NE that support regional grid investments.network.

Depreciation expense increased in 2020, as compared to 2019, dueprimarily to higher utilitynet plant in service balances, and due to the addition of EGMA utility plant balancespartially offset by a decrease in approved depreciation rates as a resultpart of the CMA asset acquisition of $10.9 million.rate case decision effective January 1, 2023 at NSTAR Electric.

Amortization expense includes the deferralsdeferral of energy supply, energy-related costs and other costs that are included in certain regulatory commission-approved cost tracking mechanisms, and the amortization of certain costs as those costs are collected in rates.  These deferrals adjustmechanisms.  This deferral adjusts expense to match the corresponding revenues. Energy supply and energy-relatedrevenues compared to the actual costs incurred. These costs are recovered from customers in rates and have no impact on earnings. Amortization decreasedexpense also includes the amortization of certain costs as those costs are collected in 2020, as compared to 2019, due to the deferrals for the under recovery of energy purchases related to the Millstone PPA at CL&P and due to the deferral of other energy supply and energy-related costs.rates.

49Amortization decreased due primarily to the deferral adjustment of energy-related and other tracked costs at CL&P (included in the non-bypassable component of the FMCC mechanism), NSTAR Electric and PSNH, which can fluctuate from period to period based on the timing of costs incurred and related rate changes to recover these costs. The decrease in the CL&P FMCC mechanism was driven primarily by the November 2022 rate relief plan, which reduced the non-bypassable FMCC rate effective January 1, 2023. The reduction in the CL&P non-bypassable FMCC retail rate decreased the regulatory over-recovery balance and created an under-recovery balance as of December 31, 2023, which resulted in a decrease to amortization expense of $802.3 million. The decrease was also driven by the impact of a new regulatory tracking mechanism at PSNH that allows for the recovery of operating expenses associated with poles acquired from Consolidated Communications on May 1, 2023. The establishment of the PPAM regulatory asset resulted in a pre-tax benefit of $16.9 million recorded in Amortization expense on the statement of income in 2023.


The decrease was partially offset by the amortization of historical exogenous property taxes that were approved for recovery effective January 1, 2023 at NSTAR Electric and effective November 1, 2022 at NSTAR Gas and EGMA, and an unfavorable regulatory adjustment resulting from NSTAR Gas’ GSEP reconciliation filing that resulted in an increase to amortization expense of $9.0 million recorded in 2023.

Energy Efficiency Programs expense increased in 2020, as compared to 2019, due primarily to the deferral adjustment and the timing of the recovery of energy efficiency costs at CL&P, PSNH and NSTAR Gas whichand EGMA, partially offset by a decrease at NSTAR Electric. The deferral adjustment reflects the actual costs of energy efficiency programs compared to the amounts billed to customers and the timing of the recovery of energy efficiency costs. The increase was also due to the addition of EGMA energy efficiency program costs as a result of the CMA asset acquisition of $14.4 million. The increase was partially offset by a decrease in spending on certain large energy efficiency projects in 2020, compared to 2019 at NSTAR Electric, due to timing.customers. The costs for the majority of the state energy policy initiatives and expanded energy efficiency programs are recovered from customers in rates and have no impact on earnings.

Taxes Other Than Income Taxes expense increased in 2020, as compared to 2019, due primarily to an increase inhigher employment-related taxes based on the timing of payroll pay periods, higher property taxes as a result of higher assessments and higher utility plant balances, and higher Connecticut gross earnings taxes at CL&P, and due to the addition of EGMA property taxes as a result of the CMA asset acquisition of $9.7 million. The increase was partially offset by a decrease of $21.4 million related to CL&P's remittance of energy efficiency funds to the State of Connecticut. Energy efficiency funds collected from customers after July 1, 2019 are no longer subject to remittance to the State of Connecticut. The increase was also partially offset by a decrease in property tax at NSTAR Gas relating to the resolution of disputed property taxes for prior years.

Impairment of Northern Pass Transmission reflects an impairment charge of $239.6 million that was recorded in the second quarter of 2019 as a result of the July 19, 2019 New Hampshire Supreme Court decision. The after-tax impact of this impairment charge was $204.4 million.taxes.

Interest Expense increased in 2020, as compared to 2019, due primarily to an increase in interest on long-term debt as a result of new debt issuances ($27.3200.3 million) and, an increase in interest on short-term notes payable ($43.8 million), higher amortization of debt discounts and premiums, net ($4.62.7 million), and an increase in interest expense on regulatory deferrals ($1.3 million), partially offset by a decrease in interest on notes payable ($16.9 million), a decrease in interest expense at NSTAR Gas relating to the resolution of disputed property taxes for prior years ($5.7 million), and an increase in capitalized AFUDC related to debt funds and other capitalized interest ($3.663.1 million), and a decrease in RRB interest expense ($1.3 million).

Impairments of Offshore Wind Investments relates to impairment charges in the second and fourth quarters of 2023 associated with Eversource’s offshore wind equity method investments resulting from the expected sale of the 50 percent interests in three jointly-owned offshore wind projects. See "Business Development and Capital Expenditures – Offshore Wind Business" included in this Management's Discussion and Analysis of Financial Condition and Results of Operations.

Other Income, Net decreased in 2020, as compared to 2019,increased due primarily to a decrease in equity in earnings related to Eversource's equity method investments ($28.0 million), the absence in 2020 of the recognition of the equity component of the carrying charges related to PSNH storm costs recordedan increase in interest income in the first quarter of 2019primarily from regulatory deferrals ($5.243.7 million) and loweran increase in capitalized AFUDC related to equity funds ($3.030.8 million), partially offset by an increasea decrease related to pension, SERP and PBOP non-service income components ($13.186.9 million), a loss on the disposition of land in 2023 compared to gains on the sales of property in 2022 ($9.0 million), a decrease in equity in earnings related to Eversource’s equity method investments ($7.4 million), and investment losses in 2023 compared to investment income in 2022 driven by market volatility ($6.8 million). Other Income, Net also increased due to a benefit in 2023 from the liquidation of Eversource’s equity method investment in a renewable energy fund in excess of its carrying value, partially offset by a charitable contribution made with a portion of the proceeds from the liquidation in 2023.

Income Tax Expense increased in 2020, as compared to 2019,decreased due primarily to higherlower pre-tax earnings ($23.5449.6 million), higherlower state taxes ($12.63.4 million), by the absence in 2020 of the impairment of NPT ($35.2 million), by a decrease in tax planning benefits ($9.5 million), the sale of Hingham water system ($12.5 million), return to provision adjustments ($3.3 million), and an increase in items that impact our tax rate as a result of regulatory treatment (flow-through items) and permanent differences ($4.1 million), partially offset by an increase in share-based payment excess tax benefits ($5.17.4 million), an increase in amortization of EDIT ($11.32.4 million), and a decreaselower return to provision adjustments ($66.7 million), partially offset by lower share-based payment excess tax benefits ($2.6 million), and an increase in reserves ($233.0 million) primarily related to the impairment of Eversource’s offshore wind investment valuation allowance ($11.6 million).reserve of $224.0 million and $8.8 million relating to an uncertain tax position.

NSTAR Electric's distribution revenues increased $32.6$37.4 million due primarily to the impact of itsa base distribution rate increase effective January 1, 2020.2023.
PSNH's distribution revenues increased $24.9decreased $0.8 million due primarily to the impacta decrease in sales volumes as a result of its temporarymilder weather in 2023 compared to 2022, partially offset by a base distribution rate increase effective JulyAugust 1, 2019, which includes recovery of storm costs and certain other items that do not impact earnings.
The increase in PSNH’s total distribution revenues was partially offset by the impact of the December 2020 settlement agreement driven by the negative impact from the over-refunding of the change in the 2018 federal corporate income tax rate as a result of the Tax Cuts and Jobs Act of 2017 that was reflected in temporary rates.2022.

Tracked Distribution Revenues: Tracked distribution revenues consist of certain costs that are recovered from customers in retail rates through regulatory commission-approved cost tracking mechanisms and therefore, recovery of these costs has no impact on earnings. However, tracked revenues doRevenues from certain of these cost tracking mechanisms also include certain incentives earned, return on rate base and on capital tracking mechanisms, and carrying charges that are billed in rates to customers, which do impact earnings. Costs recovered through cost tracking mechanisms include, among others, energy supply procurement and other energy-related costs, retail transmission charges, energy efficiency program costs, electric restructuring and stranded cost recovery revenues (including securitized RRB charges), certain capital tracking mechanisms for infrastructure improvements, and additionally for NSTAR Electric, pension and PBOP benefits, and net metering for distributed generation.generation, and solar-related programs. Tracked revenues also include wholesale market sales transactions, such as sales of energy and energy-related products into the ISO-NE wholesale electricity market and the sale of RECs to various counterparties.

51Customers have the choice to purchase electricity from each Eversource electric utility or from a competitive third party supplier. For customers who have contracted separately with these competitive suppliers, revenue is not recorded for the sale of the electricity commodity, as the utility is acting as an agent on behalf of the third party supplier. For customers that choose to purchase electric generation from CL&P, NSTAR Electric or PSNH, each purchases power on behalf of, and is permitted to recover the related energy supply cost without mark-up from, its customers, and records offsetting amounts in revenues and purchased power related to this energy supply procurement. CL&P, NSTAR Electric and PSNH each remain as the distribution service provider for all customers and charge a regulated rate for distribution delivery service recorded in revenues.

The decrease in energy supply procurement at NSTAR Electric reflects both lower average prices andPSNH was driven by lower average supply-related sales volumes, for 2020,partially offset by higher average prices. Fluctuations in retail transmission revenues are driven by the recovery of the costs of our wholesale transmission business, such as compared to 2019.those billed by ISO-NE and Local and Regional Network Service charges. For further information, see "Purchased Power and Transmission" expense below.

The increasedecrease in CL&P’s FMCC revenues was driven by a decrease in the retail Non-Bypassable Federally Mandated Congestion Charge (NBFMCC) rate, which reflects the impact of returning net benefits of higher wholesale market sales received in the ISO-NE market for long-term state approved energy contracts at CL&P, FMCC regulatory tracking mechanismwhich are then credited back to customers through the retail NBFMCC rate. CL&P’s average NBFMCC rate in effect from January 1, 2022 through April 30, 2022 was $0.01423 per kWh and from May 1 through August 31, 2022 was $0.01251 per kWh. As a result of the CL&P RAM proceeding in Docket No. 22-01-03, CL&P reduced the average NBFMCC rate effective September 1, 2022 from $0.01251 per kWh to $0.00000 per kWh. As part of a November 2022 rate relief plan, CL&P further reduced the average NBFMCC rate effective January 1, 2023 to a credit of $0.01524 per kWh. These rate reductions returned to customers the net revenues generated by long-term state-approved energy contracts with the Millstone and Seabrook nuclear power plants. The average NBFMCC rate changed to $0.00000 per kWh effective July 1, 2023. As a result of the increase2023 CL&P RAM decision, the average NBFMCC rate changed to $0.00293 per kWh effective September 1, 2023.

The decrease in wholesale market sales revenue was due primarily to lower average electricity market prices received for wholesale sales at CL&P, NSTAR Electric and PSNH. ISO-NE average market prices received for CL&P’s wholesale sales decreased to an average price of $36.60 per MWh in 2023, as compared to $82.88 per MWh in 2022, driven primarily by lower natural gas prices in New England. CL&P’s volumes sold into the newmarket were primarily from the sale of output generated by the Millstone PPA and Seabrook PPA that CL&P entered into by CL&P in 2019, as required by regulation. Beginning in the fourth quarter of 2019, CL&P sells the energy purchased from Millstone and Seabrook into the wholesale market and uses the proceeds from the energy sales to offset a portion of the contract costs. The net costs under the contract aresales or net cost amount is refunded to, or recovered from, customers in the non-bypassable component of the CL&P FMCC rate.

Transmission Revenues: Transmission revenues increased $61.7$21.9 million at CL&P, $54.2$36.1 million at NSTAR Electric and $31.2$49.2 million at PSNH in 2020, as compared to 2019, due primarily to a higher transmission rate base as a result of our continued investment in our transmission infrastructure and a higher benefit from the annual billing and cost reconciliation filing with FERC.infrastructure.

Purchased Power Costs: IncludedThe variance in purchased powerenergy supply procurement costs is offset in Operating Revenues (tracked energy supply procurement revenues). The variance in other electric distribution costs at CL&P is due to higher long-term contractual energy-related costs that are recovered in the non-bypassable component of the FMCC mechanism, at NSTAR Electric is due to a decrease in long-term renewable contract costs associated with providing electric generation service supplyand lower net metering costs, and at PSNH is due primarily to all customers who have not migrated to third party suppliers and the cost of energy purchase contracts, as required by regulation.higher net metering costs.

The increase at CL&P was due primarily to the new Millstone PPA energy purchases and higher average supply-related sales volumes, partially offset by lower average prices.
The decrease at NSTAR Electric was due primarily to lower expense related to the procurement of energy supply resulting from lower average prices and lower average supply-related sales volumes.
The decrease at PSNH was due primarily to lower expense related to the procurement of energy supply resulting from lower average prices, partially offset by higher average supply-related sales volumes.

Transmission Costs: Included in transmission costs are charges that recover the cost of transporting electricity over high-voltage lines from generation facilities to substations, including costs allocated by ISO-NE to maintain the wholesale electric market.

The decreaseincrease in transmission costs at CL&P was due primarily to a reduction toan increase in Local Network Service charges, which reflect the cost of transmission service provided by Eversource over our local transmission network, and an increase resulting from the retail transmission cost deferral, which reflects the actual costs of transmission service compared to estimated amounts billed to customers.

Depreciation expense increased in 2020, as compared to 2019, for CL&P, NSTAR Electric and PSNH due to higher net plant in service balances. The increase at NSTAR Electric was partially offset by a decrease in approved depreciation rates as part of the rate case decision effective January 1, 2023.

Amortization of Regulatory (Liabilities)/Assets, Net expense includes the deferralsdeferral of energy supply, energy-related costs and other costs that are included in certain regulatory-approvedregulatory commission-approved cost tracking mechanisms, and the amortization of certain costs as those costs are collected in rates. These deferrals adjustmechanisms. This deferral adjusts expense to match the corresponding revenues. Energy supply and energy-relatedrevenues compared to the actual costs incurred. These costs are recovered from customers in rates and have no impact on earnings. Amortization expense also includes the amortization of certain costs as those costs are collected in rates. The variance in Amortization of Regulatory (Liabilities)/Assets, Net increased at CL&P and decreased at NSTAR Electric and PSNH in 2020, as compared to 2019,is due primarily to the deferralsfollowing:

The decrease at CL&P was due primarily to the deferral adjustment of energy supplyenergy-related and energy-relatedother tracked costs that are included in the non-bypassable component of the FMCC mechanism, which can fluctuate from period to period based on the timing of costs incurred and related rate changes to recover these costs. The decrease in the FMCC mechanism was driven primarily by the CL&P November 2022 rate relief plan, which reduced the non-bypassable FMCC rate effective January 1, 2023. The reduction in the CL&P non-

bypassable FMCC retail rate decreased the regulatory over-recovery balance and created an under-recovery balance as of December 31, 2023, which resulted in a decrease to amortization expense of $802.3 million.
The decrease at NSTAR Electric was due to the deferral adjustment of energy-related costs and other tracked costs, partially offset by an increase due to the amortization of historical exogenous property taxes that were approved for recovery effective January 1, 2023 in the November 2022 NSTAR Electric distribution rate case decision.
The decrease at PSNH was due to the deferral adjustment of energy-related and other tracked costs, as well as the impact of a new regulatory tracking mechanism at PSNH that allows for the recovery of operating expenses associated with poles acquired from Consolidated Communications on May 1, 2023. The establishment of the PPAM regulatory asset resulted in a pre-tax benefit of $16.9 million recorded in Amortization expense on the PSNH statement of income in 2023.

Energy Efficiency Programs expense includes costs of various state energy policy initiatives and expanded energy efficiency programs that are recovered from customers in rates, most of which have no impact on earnings.

EARNINGS SUMMARY

CL&P's earnings increased $47.0decreased $14.2 million in 2020,2023, as compared to 2019,2022, due primarily to higher operations and maintenance expense, higher interest expense, higher depreciation expense, lower pension income, a higher effective tax rate, and higher property and other tax expense. The earnings decrease was partially offset by higher earnings from its capital tracking mechanism due to increased electric system improvements.

NSTAR Electric's earnings increased $52.1 million in 2023, as compared to 2022, due primarily to higher revenues as a result of the base distribution rate increasesincrease effective MayJanuary 1, 2020 and May 1, 2019,2023, an increase in transmission earnings driven by a higher transmission rate base, and higher earnings from its capital tracker mechanism due to increased electric system improvements. The earnings increase was partially offset by higher depreciation expense, higher propertytax expense, and higher interest expense.

NSTAR Electric's earnings increased $13.0 million in 2020, as compared to 2019, due primarily to the base distribution rate increase effective January 1, 2020, an increase in transmission earnings driven by a higher transmission rate base,interest income primarily on regulatory deferrals, and higher energy efficiency incentives earned.AFUDC equity income. The earnings increase was partially offset by higher operations and maintenance expense, higher interestproperty and other tax expense, higher depreciationinterest expense, and higher property taxdepreciation expense.

PSNH's earnings increased $13.3$24.1 million in 2020,2023, as compared to 2019,2022, due primarily to the temporary base distribution rate increase effective July 1, 2019, an increase in transmission earnings driven by a higher transmission rate base and the impact of thea new regulatory tracking mechanism at PSNH rate settlement agreement approved in December 2020 that was due primarily to the reconciliation of permanent rates back to the temporary rate period. The settlement agreement primarily resulted in a benefit to income tax expenseallows for the reductionrecovery of the EDIT regulatory liability, partially offset by a reduction in revenues driven by the negative impact from the over-refunding of the change in the 2018 federal corporate income tax rate as a result of the Tax Cuts and Jobs Act of 2017 that was reflected in temporary rates.previously incurred operating expenses associated with poles acquired on May 1, 2023. The earnings increase was partially offset by higher operations and maintenanceinterest expense, higher property taxdepreciation expense, and the absence of the 2019 recognition of carrying charges on its 2013 through 2016 storm costs approved for recovery.lower pension income.

Item 7A.    Quantitative and Qualitative Disclosures about Market Risk

Market Risk Information

Commodity Price Risk Management:  Our regulated companies enter into energy contracts to serve our customers, and the economic impacts of those contracts are passed on to our customers.  Accordingly, the regulated companies have no exposure to loss of future earnings or fair values due to these market risk-sensitive instruments.  Eversource's Energy Supply Risk Committee, comprised of senior officers, reviews and approves all large-scale energy related transactions entered into by its regulated companies.

Other Risk Management Activities

We have an Enterprise Risk Management (ERM) program for identifying the principal risks of the Company.  Our ERM program involves the application of a well-defined, enterprise-wide methodology designed to allow our Risk Committee, comprised of our senior officers of the Company, to identify, categorize, prioritize, and mitigate the principal risks to the Company.  The ERM program is integrated with other assurance functions throughout the Company including Compliance, Auditing, and Insurance to ensure appropriate coverage of risks that could impact the Company.  In addition to known risks, ERM identifies emerging risks to the Company, through participation in industry groups, discussions with management and in consultation with outside advisers.  Our management then analyzes risks to determine materiality, likelihood and impact, and develops mitigation strategies.  Management broadly considers our business model, the utility industry, the global economy, climate change, sustainability and the current environment to identify risks.  The Finance Committee of the Board of Trustees is responsible for oversight of the Company's ERM program and enterprise-wide risks as well as specific risks associated with insurance, credit, financing, investments, pensions and overall system security including cyber security.  The findings of the ERM process are periodically discussed with the Finance Committee of our Board of Trustees, as well as with other Board Committees or the full Board of Trustees, as appropriate, including reporting on how these issues are being measured and managed.  However, there can be no assurances that the ERM process will identify or manage every risk or event that could impact our financial position, results of operations or cash flows.

Interest Rate Risk Management:  We manageInterest rate risk is associated with changes in interest rates for our outstanding long-term debt. Our interest rate risk exposure in accordance withis significantly reduced as typically all or most of our written policies and procedures by maintaining a mix ofdebt financings have fixed and variable rate long-term debt.interest rates.  As of December 31, 2020,2023, all of our long-term debt except for $11.7 million of fees and interest due for CYAPC's spent nuclear fuel disposal costs, was at a fixed interest rate.

Credit Risk Management:  Credit risk relates to the risk of loss that we would incur as a result of non-performance by counterparties pursuant to the terms of our contractual obligations.  We serve a wide variety of customers and transact with suppliers that include IPPs, industrial companies, natural gas and electric utilities, oil and natural gas producers, financial institutions, and other energy marketers.  Margin accounts exist within this diverse group, and we realize interest receipts and payments related to balances outstanding in these margin accounts.  This wide customer and supplier mix generates a need for a variety of contractual structures, products and terms that, in turn, require us to manage the portfolio of market risk inherent in those transactions in a manner consistent with the parameters established by our risk management process.

Our regulated companies are subject to credit risk from certain long-term or high-volume supply contracts with energy marketing companies.  Our regulated companies manage the credit risk with these counterparties in accordance with established credit risk practices and monitor contracting risks, including credit risk.  As of December 31, 2020,2023, our regulated companies held collateral (letters of credit or cash) of $10.0$32.0 million from counterparties related to our standard service contracts. As of December 31, 2020,2023, Eversource had $34.6$28.7 million of cash posted with ISO-NE related to energy transactions.

For further information on cash collateral deposited and posted with counterparties, see Note 1O, "Summary of Significant Accounting Policies - Supplemental Cash Flow Information," to the financial statements.

If the respective unsecured debt ratings of Eversource or its subsidiaries were reduced to below investment grade by either Moody's, S&P or S&P,Fitch, certain of Eversource's contracts would require additional collateral in the form of cash or letters of credit to be provided to counterparties and independent system operators.  Eversource would have been and remains able to provide that collateral.

Management’s Report on Internal Controls Over Financial Reporting

Eversource Energy

Management is responsible for the preparation, integrity, and fair presentation of the accompanying consolidated financial statements of Eversource Energy and subsidiaries (Eversource or the Company) and of other sections of this annual report.  Eversource's internal controls over financial reporting were audited by Deloitte & Touche LLP.

Management is responsible for establishing and maintaining adequate internal controls over financial reporting.  The Company's internal control framework and processes have been designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.  There are inherent limitations of internal controls over financial reporting that could allow material misstatements due to error or fraud to occur and not be prevented or detected on a timely basis by employees during the normal course of business.  Additionally, internal controls over financial reporting may become inadequate in the future due to changes in the business environment.  

Under the supervision and with the participation of the principal executive officer and principal financial officer, Eversource conducted an evaluation of the effectiveness of internal controls over financial reporting based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  Based on this evaluation under the framework in COSO, management concluded that internal controls over financial reporting were effective as of December 31, 2020.2023.

Management has excluded from our assessment of and conclusion on the effectiveness of internal controls over financial reporting the internal
controls of Eversource Gas Company of Massachusetts (EGMA). On October 9, 2020, Eversource completed the acquisition of certain assets and liabilities that comprised NiSource’s natural gas distribution business in Massachusetts, which was previously doing business as Columbia Gas of Massachusetts (CMA). The natural gas distribution assets acquired from CMA were assigned to EGMA, and are included in the consolidated financial statements of the Company as of and for the year ended December 31, 2020, constituting 3.4 percent and 5.8 percent of total and net assets, respectively, as of December 31, 2020, and 1.7 percent and 1.2 percent of revenues and net income attributable to common shareholders, respectively, for the year ended December 31, 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Trustees and Shareholders of Eversource Energy:
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Eversource Energy and subsidiaries (the “Company”) as of December 31, 2020,2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020,2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
As described in the Management’s Report on Internal Controls Over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Eversource Gas Company of Massachusetts (previously doing business as Columbia Gas of Massachusetts), which was acquired on October 9, 2020, and whose financial statements constitute 3.4% and 5.8% of total and net assets, respectively, 1.7% of revenues, and 1.2% of net income attributable to common shareholders of the consolidated financial statement amounts as of and for the year ended December 31, 2020. Accordingly, our audit did not include the internal control over financial reporting at Eversource Gas Company of Massachusetts.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2020,2023, of the Company and our report dated February 17, 2021,14, 2024, expressed an unqualified opinion on those financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Controls Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Regulatory Accounting - Impact of Rate Regulation on the Financial Statements - Refer to Note 2 to the Financial Statements

Critical Audit Matter Description

The Company’s utility companies are subject to rate regulation by the Federal Energy Regulatory Commission and by their respective state public utility authorities in Connecticut, Massachusetts, or New Hampshire (the “Commissions”). The rate regulation by these Commissions is based on cost recovery. The regulated companies’ financial statements reflect the effects of the rate-making process. The rates charged to the customers of the Company’s regulated companies are designed to collect each company’s cost to provide service, plus a return on investment.

The application of accounting guidance for rate-regulated enterprises results in recording regulatory assets and liabilities. Regulatory assets represent the deferral of incurred costs that are probable of future recovery in customer rates. Regulatory assets are amortized as the incurred costs are recovered through customer rates. In some cases, the Company records regulatory assets before approval for recovery has been received from the applicable regulatory commission. The Company must use judgment to conclude that costs deferred as regulatory assets are probable of future recovery. The Company bases its conclusion on certain factors, including, but not limited to, regulatory precedent. Regulatory liabilities represent either revenues received from customers to fund expected costs that have not yet been incurred or probable future refunds to customers.

The Company uses judgment when recording regulatory assets and liabilities; however, regulatory commissions can reach different conclusions about the recovery of costs, and those conclusions could have a material impact on the Company’s financial statements. Management believes it is probable that each of the regulated companies will recover its respective investment in long-lived assets, including regulatory assets. If management were to determine that it could no longer apply the accounting guidance applicable to rate-regulated enterprises to any of the regulated companies’ operations, or if management could not conclude it is probable that costs would be recovered from customers in future rates, the costs would be charged to net income in the period in which the determination is made.

Accounting for the economics of rate-regulation impacts multiple financial statement line items and disclosures, such as regulated property, plant, and equipment, regulatory assets and liabilities, operating revenues, depreciation expense and depreciation expense.amortization of regulatory assets. While management has indicated it expects to recover costs from customers through regulated rates, there is a risk that the Commissions will not approve full recovery of such costs or full recovery of all amounts invested in the utility business and a reasonable return on that investment. We identified the impact of rate-regulation as a critical audit matter due to the significant judgments made by management to support its assertions about impact of future regulatory orders on the financial statements. Management judgments include assessing the probability of recovery in future rates of incurred costs and of a refund to customers. Given that management’s accounting judgments are based on assumptions about the outcome of future decisions by the Commissions, auditing these judgments requires specialized knowledge of accounting for rate regulation and the rate setting process due to its inherent complexities.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the uncertainty of future decisions by the Commissions included the following, among others:

• We tested the effectiveness of management’s controls over the evaluation of the likelihood of (1) the recovery in future rates of costs incurred as property, plant, and equipment and deferred as regulatory assets, and (2) a refund or a future reduction in rates that should be reported as regulatory liabilities. We tested the effectiveness of management’s controls over the initial recognition of amounts as property, plant, and equipment; regulatory assets or liabilities; and the monitoring and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates, a refund, or a future reduction in rates.

• We evaluated the Company’s disclosures related to the applicability and impacts of rate regulation, including the balances recorded and regulatory developments disclosed in the financial statements.

• We read relevant regulatory orders issued by the Commissions for the Company and other public utilities, regulatory statutes, interpretations, procedural memorandums, filings made by intervenors, and other publicly available information to assess the likelihood of recovery in future rates or of a future refund or reduction in rates based on precedents of the Commissions’ treatment of similar costs under similar circumstances. We evaluated the external information and compared it to management’s recorded regulatory asset and liability balances for completeness.

• For regulatory matters in process, we inspected the Company’s filings with the Commissions and the filings with the Commissions by intervenors that may impact the Company’s future rates, for any evidence that might contradict management’s assertions.

• We made inquiries of management, including legal counsel, and obtained the regulatory orders and analysis from management that support the probability of recovery, refund, or future reductions in rates for regulatory assets and liabilities to assess management’s assertion that amounts are probable of recovery, refund, or a future reduction in rates.

Investments in Unconsolidated Affiliates – Impact of Offshore Wind Impairment and Offshore Wind Divestiture - Refer to Note 6 to the Financial Statements

Critical Audit Matter Description

Eversource’s offshore wind business includes 50 percent ownership interests in each of North East Offshore and South Fork Class B Member, LLC, which collectively hold three offshore wind projects. North East Offshore holds the Revolution Wind project and the Sunrise Wind project. South Fork Class B Member, LLC holds the South Fork Wind project. Eversource’s offshore wind business also includes a noncontrolling tax equity investment in South Fork Wind through a 100 percent ownership in South Fork Wind Holdings, LLC Class A shares. The offshore wind projects are being developed and constructed through joint and equal partnerships with Ørsted.

In the second quarter of 2023, the Company announced that it had completed the strategic review of its offshore wind investments and determined that it would continue to pursue the sale of its offshore wind investments. The Company also entered into a purchase and sale agreement with Ørsted for its 50% interest in an uncommitted lease area and committed to provide tax equity for the South Fork Wind project through a new tax equity ownership interest. In connection with the conclusion of the strategic review, Eversource evaluated its aggregate investment in the projects, uncommitted lease area, and other related capitalized costs and determined that the carrying value of the equity method offshore wind investment exceeded the fair value of the investment and that the decline was other-than-temporary. The estimate of fair value was based on the expected sale price of the Company’s 50 percent interest in the three contracted projects based on the most recent bid value, the sale price of the uncommitted lease area included in the purchase and sale agreement, expected investment tax credits and potential investment tax credit adder amounts, the value of the tax equity ownership interest, and the expectation of a successful repricing of the Sunrise Wind Offshore Renewable Energy Credit (“OREC”) contract. As a result, the Company recognized an other-than temporary impairment charge in the second quarter of 2023.

In the fourth quarter of 2023, The New York State Public Service Commission denied Sunrise Wind’s petition to amend its OREC contract to increase the contract price to cover increased costs and inflation. Also during the fourth quarter, project construction forecasts were updated, and these new forecasts reflected additional expenditures for construction and scheduling related pressures, including the availability and increased cost of installation vessels and supply chain cost increases related to foundation fabrication. In determining the current fair value of the investments, these updated projections exceeded the previously estimated projections for construction expenditures, which resulted in a revised sales price that is now significantly lower than the previous bid value. Accordingly, the Company also recognized an other-than temporary impairment charge in the fourth quarter of 2023.

We identified the evaluation of other-than-temporary impairment charge for the offshore wind investment as a critical audit matter. It involves a significant degree of judgment and estimation, including identifying circumstances that indicate an impairment may exist at the equity method investment level, selecting discount rates used to determine fair values, and developing an estimate of discounted future cash flows expected from
64


investment operations or the sale of the investment. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to the price and the discount rate used in the discounted future cash flow method.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the discount rate used to determine fair market values and the estimates of discounted future cash flows expected from the sale of the investment.

•    We tested the effectiveness of management’s controls over impairment considerations including the aggregate investment in the projects, the sale price of the uncommitted lease area, and other related capitalized costs, as well as the discounted cash flow analysis for the offshore wind investments. We tested the effectiveness of management’s controls over the initial recognition of the impairment charge.

•    We evaluated the Company’s disclosures related to the impairment charges disclosed in the financial statements.

•    We evaluated the assumptions utilized within the discounted cash flow model used in the Company’s impairment analysis.

•    We made inquiries of management and evaluated the full impairment analysis from management that supported the other-than-temporary impairment charge in accordance with ASC 323-10-35-32A “Equity Method and Joint Ventures – Subsequent Measurement”.

Management’s Report on Internal Controls Over Financial Reporting

The Connecticut Light and Power Company

Management is responsible for the preparation, integrity, and fair presentation of the accompanying financial statements of The Connecticut Light and Power Company (CL&P or the Company) and of other sections of this annual report.  

Management is responsible for establishing and maintaining adequate internal controls over financial reporting.  The Company's internal control framework and processes have been designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.  There are inherent limitations of internal controls over financial reporting that could allow material misstatements due to error or fraud to occur and not be prevented or detected on a timely basis by employees during the normal course of business.  Additionally, internal controls over financial reporting may become inadequate in the future due to changes in the business environment.  

Under the supervision and with the participation of the principal executive officer and principal financial officer, CL&P conducted an evaluation of the effectiveness of internal controls over financial reporting based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  Based on this evaluation under the framework in COSO, management concluded that internal controls over financial reporting were effective as of December 31, 2020.2023.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholder of The Connecticut Light and Power Company:

Opinion on the Financial Statements

We have audited the accompanying balance sheets of The Connecticut Light and Power Company (the “Company”) as of December 31, 20202023 and 2019,2022, the related statements of income, comprehensive income, common stockholder’s equity, and cash flows, for each of the three years in the period ended December 31, 2020,2023, and the related notes and the schedule listed in the Index at Item 15 of Part IV (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20202023 and 2019,2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020,2023, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Regulatory Accounting - Impact of Rate Regulation on the Financial Statements - Refer to Note 2 to the Financial Statements

Critical Audit Matter Description

The Company is subject to rate regulation by the Federal Energy Regulatory Commission and the state public utility authority in Connecticut (the “Commissions”). The rate regulation by these Commissions is based on cost recovery. The Company’s financial statements reflect the effects of the rate-making process. The rates charged to the customers are designed to collect the Company’s cost to provide service, plus a return on investment.

The application of accounting guidance for rate-regulated enterprises results in recording regulatory assets and liabilities. Regulatory assets represent the deferral of incurred costs that are probable of future recovery in customer rates. Regulatory assets are amortized as the incurred costs are recovered through customer rates. In some cases, the Company records regulatory assets before approval for recovery has been received from the applicable regulatory commission. The Company must use judgment to conclude that costs deferred as regulatory assets are probable of future recovery. The Company bases its conclusion on certain factors, including, but not limited to, regulatory precedent. Regulatory liabilities represent either revenues received from customers to fund expected costs that have not yet been incurred or probable future refunds to customers.

The Company uses judgment when recording regulatory assets and liabilities; however, regulatory commissions can reach different conclusions about the recovery of costs, and those conclusions could have a material impact on the Company’s financial statements. Management believes it is probable that the Company will recover its investment in long-lived assets, including regulatory assets. If management were to determine that it could no longer apply the accounting guidance applicable to rate-regulated enterprises to the Company’s operations, or if management could not conclude it is probable that costs would be recovered from customers in future rates, the costs would be charged to net income in the period in which the determination is made.

6671


Accounting for the economics of rate-regulation impacts multiple financial statement line items and disclosures, such as regulated property, plant, and equipment, regulatory assets and liabilities, operating revenues, depreciation expense and depreciation expense.amortization of regulatory assets. While management has indicated it expects to recover costs from customers through regulated rates, there is a risk that the Commissions will not approve full recovery of such costs or full recovery of all amounts invested in the Company and a reasonable return on that investment. We identified the impact of rate-regulation as a critical audit matter due to the significant judgments made by management to support its assertions about impact of future regulatory orders on the financial statements. Management judgments include assessing the probability of recovery in future rates of incurred costs and of a refund to customers. Given that management’s accounting judgments are based on assumptions about the outcome of future decisions by the Commissions, auditing these judgments requires specialized knowledge of accounting for rate regulation and the rate setting process due to its inherent complexities.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the uncertainty of future decisions by the Commissions included the following, among others:

• We tested the effectiveness of management’s controls over the evaluation of the likelihood of (1) the recovery in future rates of costs incurred as property, plant, and equipment and deferred as regulatory assets, and (2) a refund or a future reduction in rates that should be reported as regulatory liabilities. We tested the effectiveness of management’s controls over the initial recognition of amounts as property, plant, and equipment; regulatory assets or liabilities; and the monitoring and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates, a refund, or a future reduction in rates.

• We evaluated the Company’s disclosures related to the applicability and impacts of rate regulation, including the balances recorded and regulatory developments disclosed in the financial statements.

• We read relevant regulatory orders issued by the Commissions for the Company and other public utilities, regulatory statutes, interpretations, procedural memorandums, filings made by intervenors, and other publicly available information to assess the likelihood of recovery in future rates or of a future refund or reduction in rates based on precedents of the Commissions’ treatment of similar costs under similar circumstances. We evaluated the external information and compared it to management’s recorded regulatory asset and liability balances for completeness.

• For regulatory matters in process, we inspected the Company’s filings with the Commissions and the filings with the Commissions by intervenors that may impact the Company’s future rates, for any evidence that might contradict management’s assertions.

• We made inquiries of management, including legal counsel, and obtained the regulatory orders and analysis from management that support the probability of recovery, refund, or future reductions in rates for regulatory assets and liabilities to assess management’s assertion that amounts are probable of recovery, refund, or a future reduction in rates.

Management’s Report on Internal Controls Over Financial Reporting

NSTAR Electric Company

Management is responsible for the preparation, integrity, and fair presentation of the accompanying consolidated financial statements of NSTAR Electric Company and subsidiary (NSTAR Electric or the Company) and of other sections of this annual report.  

Management is responsible for establishing and maintaining adequate internal controls over financial reporting.  The Company's internal control framework and processes have been designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.  There are inherent limitations of internal controls over financial reporting that could allow material misstatements due to error or fraud to occur and not be prevented or detected on a timely basis by employees during the normal course of business.  Additionally, internal controls over financial reporting may become inadequate in the future due to changes in the business environment.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholder of NSTAR Electric Company:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of NSTAR Electric Company and subsidiary (the “Company”) as of December 31, 20202023 and 2019,2022, the related consolidated statements of income, comprehensive income, common stockholder’s equity, and cash flows, for each of the three years in the period ended December 31, 2020,2023, and the related notes and the schedule listed in the Index at Item 15 of Part IV (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20202023 and 2019,2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020,2023 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Regulatory Accounting - Impact of Rate Regulation on the Financial Statements - Refer to Note 2 to the Financial Statements

Critical Audit Matter Description

The Company is subject to rate regulation by the Federal Energy Regulatory Commission and the state public utility authority in Massachusetts (the “Commissions”). The rate regulation by these Commissions is based on cost recovery. The Company’s financial statements reflect the effects of the rate-making process. The rates charged to the customers are designed to collect the Company’s cost to provide service, plus a return on investment.

The application of accounting guidance for rate-regulated enterprises results in recording regulatory assets and liabilities. Regulatory assets represent the deferral of incurred costs that are probable of future recovery in customer rates. Regulatory assets are amortized as the incurred costs are recovered through customer rates. In some cases, the Company records regulatory assets before approval for recovery has been received from the applicable regulatory commission. The Company must use judgment to conclude that costs deferred as regulatory assets are probable of future recovery. The Company bases its conclusion on certain factors, including, but not limited to, regulatory precedent. Regulatory liabilities represent either revenues received from customers to fund expected costs that have not yet been incurred or probable future refunds to customers.

The Company uses judgment when recording regulatory assets and liabilities; however, regulatory commissions can reach different conclusions about the recovery of costs, and those conclusions could have a material impact on the Company’s financial statements. Management believes it is probable that the Company will recover its investment in long-lived assets, including regulatory assets. If management were to determine that it could no longer apply the accounting guidance applicable to rate-regulated enterprises to the Company’s operations, or if management could not conclude it is probable that costs would be recovered from customers in future rates, the costs would be charged to net income in the period in which the determination is made.

7378


Accounting for the economics of rate-regulation impacts multiple financial statement line items and disclosures, such as regulated property, plant, and equipment, regulatory assets and liabilities, operating revenues, depreciation expense and depreciation expense.amortization of regulatory assets. While management has indicated it expects to recover costs from customers through regulated rates, there is a risk that the Commissions will not approve full recovery of such costs or full recovery of all amounts invested in the Company and a reasonable return on that investment. We identified the impact of rate-regulation as a critical audit matter due to the significant judgments made by management to support its assertions about impact of future regulatory orders on the financial statements. Management judgments include assessing the probability of recovery in future rates of incurred costs and of a refund to customers. Given that management’s accounting judgments are based on assumptions about the outcome of future decisions by the Commissions, auditing these judgments requires specialized knowledge of accounting for rate regulation and the rate setting process due to its inherent complexities.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the uncertainty of future decisions by the Commissions included the following, among others:

• We tested the effectiveness of management’s controls over the evaluation of the likelihood of (1) the recovery in future rates of costs incurred as property, plant, and equipment and deferred as regulatory assets, and (2) a refund or a future reduction in rates that should be reported as regulatory liabilities. We tested the effectiveness of management’s controls over the initial recognition of amounts as property, plant, and equipment; regulatory assets or liabilities; and the monitoring and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates, a refund, or a future reduction in rates.

• We evaluated the Company’s disclosures related to the applicability and impacts of rate regulation, including the balances recorded and regulatory developments disclosed in the financial statements.

• We read relevant regulatory orders issued by the Commissions for the Company and other public utilities, regulatory statutes, interpretations, procedural memorandums, filings made by intervenors, and other publicly available information to assess the likelihood of recovery in future rates or of a future refund or reduction in rates based on precedents of the Commissions’ treatment of similar costs under similar circumstances. We evaluated the external information and compared it to management’s recorded regulatory asset and liability balances for completeness.

• For regulatory matters in process, we inspected the Company’s filings with the Commissions and the filings with the Commissions by intervenors that may impact the Company’s future rates, for any evidence that might contradict management’s assertions.

• We made inquiries of management, including legal counsel, and obtained the regulatory orders and analysis from management that support the probability of recovery, refund, or future reductions in rates for regulatory assets and liabilities to assess management’s assertion that amounts are probable of recovery, refund, or a future reduction in rates.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20202023 and 2019,2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020,2023, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Regulatory Accounting - Impact of Rate Regulation on the Financial Statements - Refer to Note 2 to the Financial Statements

Critical Audit Matter Description

The Company is subject to rate regulation by the Federal Energy Regulatory Commission and the state public utility authority in New Hampshire (the “Commissions”). The rate regulation by these Commissions is based on cost recovery. The Company’s financial statements reflect the effects of the rate-making process. The rates charged to the customers are designed to collect the Company’s cost to provide service, plus a return on investment.

The application of accounting guidance for rate-regulated enterprises results in recording regulatory assets and liabilities. Regulatory assets represent the deferral of incurred costs that are probable of future recovery in customer rates. Regulatory assets are amortized as the incurred costs are recovered through customer rates. In some cases, the Company records regulatory assets before approval for recovery has been received from the applicable regulatory commission. The Company must use judgment to conclude that costs deferred as regulatory assets are probable of future recovery.

Regulatory liabilities represent either revenues received from customers to fund expected costs that have not yet been incurred or probable future refunds to customers.

The Company uses judgment when recording regulatory assets and liabilities; however, regulatory commissions can reach different conclusions about the recovery of costs, and those conclusions could have a material impact on the Company’s financial statements. Management believes it is probable that the Company will recover its investment in long-lived assets, including regulatory assets. If management were to determine that it could no longer apply the accounting guidance applicable to rate-regulated enterprises to the Company’s operations, or if management could not conclude it is probable that costs would be recovered from customers in future rates, the costs would be charged to net income in the period in which the determination is made.

Accounting for the economics of rate-regulation impacts multiple financial statement line items and disclosures, such as regulated property, plant, and equipment, regulatory assets and liabilities, operating revenues, depreciation expense and depreciation expense.amortization of regulatory assets. While management has indicated it expects to recover costs from customers through regulated rates, there is a risk that the Commissions will not approve full recovery of such costs or full recovery of all amounts invested in the Company and a reasonable return on that investment. We identified the impact of rate-regulation as a critical audit matter due to the significant judgments made by management to support its assertions about impact of future regulatory orders on the financial statements. Management judgments include assessing the probability of recovery in future rates of incurred costs and of a refund to customers. Given that management’s accounting judgments are based on assumptions about the outcome of future decisions by the Commissions, auditing these judgments requires specialized knowledge of accounting for rate regulation and the rate setting process due to its inherent complexities.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the uncertainty of future decisions by the Commissions included the following, among others:

• We tested the effectiveness of management’s controls over the evaluation of the likelihood of (1) the recovery in future rates of costs incurred as property, plant, and equipment and deferred as regulatory assets, and (2) a refund or a future reduction in rates that should be reported as regulatory liabilities. We tested the effectiveness of management’s controls over the initial recognition of amounts as property, plant, and equipment; regulatory assets or liabilities; and the monitoring and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates, a refund, or a future reduction in rates.

• We evaluated the Company’s disclosures related to the applicability and impacts of rate regulation, including the balances recorded and regulatory developments disclosed in the financial statements.

• We read relevant regulatory orders issued by the Commissions for the Company and other public utilities, regulatory statutes, interpretations, procedural memorandums, filings made by intervenors, and other publicly available information to assess the likelihood of recovery in future rates or of a future refund or reduction in rates based on precedents of the Commissions’ treatment of similar costs under similar circumstances. We evaluated the external information and compared it to management’s recorded regulatory asset and liability balances for completeness.

• For regulatory matters in process, we inspected the Company’s filings with the Commissions and the filings with the Commissions by intervenors that may impact the Company’s future rates, for any evidence that might contradict management’s assertions.

• We made inquiries of management, including legal counsel, and obtained the regulatory orders and analysis from management that support the probability of recovery, refund, or future reductions in rates for regulatory assets and liabilities to assess management’s assertion that amounts are probable of recovery, refund, or a future reduction in rates.

COMBINED NOTES TO FINANCIAL STATEMENTS

Refer to the Glossary of Terms included in this combined Annual Report on Form 10-K for abbreviations and acronyms used throughout the combined notes to the financial statements.

1.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A.     About Eversource, CL&P, NSTAR Electric and PSNH
Eversource Energy is a public utility holding company primarily engaged, through its wholly-owned regulated utility subsidiaries, in the energy delivery business.  Eversource Energy's wholly-owned regulated utility subsidiaries consist of CL&P, NSTAR Electric and PSNH (electric utilities), Yankee Gas, NSTAR Gas and Eversource Gas Company of Massachusetts (EGMA)EGMA (natural gas utilities), and Aquarion (water utilities). Eversource provides energy delivery and/or water service to approximately 4.34.4 million electric, natural gas and water customers through 9twelve regulated utilities in Connecticut, Massachusetts and New Hampshire.

On October 9, 2020, Eversource completed the acquisition of certain assets and liabilities that comprised NiSource’s natural gas distribution business in Massachusetts, which was previously doing business as Columbia Gas of Massachusetts (CMA). The natural gas distribution assets acquired from CMA were assigned to EGMA, an indirect wholly-owned subsidiary of Eversource formed in 2020. The LNG assets acquired from CMA were assigned to Hopkinton LNG Corp. The cash purchase price was $1.1 billion, plus a target working capital amount of $69.6 million, which is subject to adjustment to reflect actual working capital as of the closing date that has not yet been finalized. Eversource's consolidated financial information includes the results of EGMA beginning from the date of acquisition on October 9, 2020. See Note 24, "Acquisition of Assets of Columbia Gas of Massachusetts," for further information.

Eversource, CL&P, NSTAR Electric and PSNH are reporting companies under the Securities Exchange Act of 1934.  Eversource Energy is a public utility holding company under the Public Utility Holding Company Act of 2005.  Arrangements among the regulated electric companies and other Eversource companies, outside agencies and other utilities covering interconnections, interchange of electric power and sales of utility property are subject to regulation by the FERC. Eversource's regulated companies are subject to regulation of rates, accounting and other matters by the FERC and/or applicable state regulatory commissions (the PURA for CL&P, Yankee Gas and Aquarion, the DPU for NSTAR Electric, NSTAR Gas, EGMA and Aquarion, and the NHPUC for PSNH and Aquarion).

CL&P, NSTAR Electric and PSNH furnish franchised retail electric service in Connecticut, Massachusetts and New Hampshire.Hampshire, respectively. NSTAR Gas and EGMA are engaged in the distribution and sale of natural gas to customers within Massachusetts and Yankee Gas is engaged in the distribution and sale of natural gas to customers within Connecticut. Aquarion is engaged in the collection, treatment and distribution of water in Connecticut, Massachusetts and New Hampshire. CL&P, NSTAR Electric and PSNH's results include the operations of their respective distribution and transmission businesses. The distribution business also includes the results of NSTAR Electric's solar power facilities and PSNH's generation facilities prior to sale in 2018. PSNH completed the sales of all its thermal and hydroelectric generation assets in 2018.facilities.

Eversource Service, Eversource's service company, and several wholly-owned real estate subsidiaries of Eversource, provide support services to Eversource, including its regulated companies.

B.     Basis of Presentation
The consolidated financial statements of Eversource, NSTAR Electric and PSNH include the accounts of each of their respective subsidiaries. Intercompany transactions have been eliminated in consolidation.  The accompanying consolidated financial statements of Eversource, NSTAR Electric and PSNH and the financial statements of CL&P are herein collectively referred to as the "financial statements."  

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Eversource consolidates the operations of CYAPC and YAEC both of which are inactive regional nuclear power companies engaged in the long-term storage of their spent nuclear fuel. Eversource consolidates the operations of CYAPC and YAEC because CL&P's, NSTAR Electric's and PSNH's combined ownership and voting interests in each of these entities is greater than 50 percent.  Intercompany transactions between CL&P, NSTAR Electric, PSNH and the CYAPC and YAEC companies have been eliminated in consolidation of the Eversource financial statements.  

Eversource holds several equity ownership interests that are not consolidated and are accounted for under the equity method.method, including 50 percent ownership interests in three offshore wind projects and a tax equity investment in one of the projects. See Note 6, “Investments in Unconsolidated Affiliates,” for further information on Eversource’s equity method investments and impairment charges recorded in 2023 to the offshore wind investments carrying value.

86


In accordance with accounting guidance on noncontrolling interests in consolidated financial statements, the Preferred Stock of CL&P and the Preferred Stock of NSTAR Electric, which are not owned by Eversource or its consolidated subsidiaries and are not subject to mandatory redemption, have been presented as noncontrolling interests in the financial statements of Eversource.  The Preferred Stock of CL&P and the Preferred Stock of NSTAR Electric are considered to be temporary equity and have been classified between liabilities and permanent shareholders' equity on the balance sheets of Eversource, CL&P and NSTAR Electric due to a provision in the preferred stock agreements of both CL&P and NSTAR Electric that grant preferred stockholders the right to elect a majority of the CL&P and NSTAR Electric Boards of Directors, respectively, should certain conditions exist, such as if preferred dividends are in arrears for a specified amount of time.  The Net Income reported in the statements of income and cash flows represents net income prior to apportionment to noncontrolling interests, which is represented by dividends on preferred stock of CL&P and NSTAR Electric.

91


Eversource's utility subsidiaries' electric, natural gas and water distribution and transmission businesses are subject to rate-regulation that is based on cost recovery and meets the criteria for application of accounting guidance for entities with rate-regulated operations, which considers the effect of regulation on the differences in the timing of the recognition of certain revenues and expenses from those of other businesses and industries. See Note 2, "Regulatory Accounting," for further information.

COVID-19 has adversely affected workers and the economy and caused volatility in the financial markets. Due to the inherent uncertainty of the unprecedented and evolving situation, we continue to closely monitor how COVID-19 related developments affect Eversource. Based on available information, we have not experienced significant impacts directly related to the pandemic that have adversely affected our current operations or results of operations. The extent of the impact to us in the future will vary and depend in large part on the duration, scope and severity of the pandemic and the timing and extent of COVID-19 relief legislation, and the resulting impact on economic, health care and capital market conditions. The future impact will also depend on the outcome of planned proceedings before our state regulatory commissions to recover our incremental costs associated with COVID-19.

We believe that we have in place, or are developing, successful mechanisms with our state regulatory commissions that allow, or will allow, us to recover our incremental costs associated with COVID-19, which include uncollectible customer receivable expenses, while balancing the impact on our customers’ bills and our operating cash flows. See Note 1F, "Summary of Significant Accounting Policies - Allowance for Uncollectible Accounts," for discussion of our evaluation of the allowance for doubtful accounts as of December 31, 2020 in light of the COVID-19 pandemic.

An extended economic slowdown has resulted in lower demand for electricity, natural gas and/or water by our commercial and industrial customers. However, fluctuations in retail sales volumes for CL&P, NSTAR Electric, Yankee Gas, NSTAR Gas, EGMA, and our Connecticut water distribution business do not materially impact earnings due to their respective state regulatory commission-approved distribution revenue decoupling mechanisms.

As of December 31, 2020, we did not identify indicators or triggering events for impairments to our goodwill, long-lived assets, available-for-sale debt securities, or equity method investment carrying values.

Certain reclassifications of prior year data were made in the accompanying financial statements to conform to the current year presentation.

As of December 31, 20202023 and 2019,2022, Eversource's carrying amount of goodwill was approximately $4.45$4.53 billion and $4.43$4.52 billion, respectively. Eversource performs an assessment for possible impairment of its goodwill at least annually.  Eversource completed its annual goodwill impairment assessment for each of its reporting units as of October 1, 20202023 and determined that no impairment exists.  See Note 25,24, "Goodwill," for further information.

C.     Accounting Standards
Accounting Standards Issued but Not Yet Effective: In December 2019,Certain reclassifications of prior year data were made in the FASB issued Accounting Standards Update (ASU) 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes, which eliminates certain exceptionsaccompanying financial statements to conform to the general principles of current income tax guidance in ASC 740 and simplifies and improves consistency in application of that income tax guidance through clarifications of and amendments to ASC 740. The guidance is effective in the first quarter of 2021. The ASU is not expected to have a material impact on the financial statements of Eversource, CL&P, NSTAR Electric and PSNH.year presentation.

Accounting Standards Recently Adopted: On January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which provides a model for recognizing credit losses on financial instruments based on an estimate of current expected losses, requiring immediate recognition of credit losses expected over the life of a financial instrument. The Company determined the impacts of this standard on the allowance for credit losses on its financial instruments, primarily accounts receivable.  As of January 1, 2020, the Company recorded increases to the allowance for uncollectible accounts for late feesC.     Cash and other receivable amounts of $1.6 million, $0.9 million, $0.2 million and $0.3 million at Eversource, CL&P, NSTAR Electric and PSNH, respectively. The impact to retained earnings, net of tax, was $1.5 million, $0.9 million, $0.2 million and $0.3 million at Eversource, CL&P, NSTAR Electric and PSNH, respectively.

The Company also adjusted the allowance for uncollectible amounts of hardship receivables and other low-income assistance programs, which are ultimately collectible in rates at specified points in time under approved regulatory mechanisms. The impact on the allowance, which was offset in other long-term assets on the balance sheets, was an increase of $22.2 million and $21.3 million at Eversource and CL&P, respectively, and a decrease of $1.5 million at NSTAR Electric as of January 1, 2020. See Note 1F, “Summary of Significant Accounting Policies - Allowance for Uncollectible Accounts,” for further information.

87


The Company adopted ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment as of January 1, 2020. The ASU simplified the accounting for goodwill impairment by removing a complex step in the goodwill impairment test. Under the guidance, goodwill impairment is measured as the amount by which its carrying value exceeds its fair value. The ASU did not have an impact on the financial statements of Eversource.

On January 1, 2020, the Company adopted ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The ASU aligned the requirements for capitalizing costs incurred to implement a cloud computing arrangement with existing internal-use software guidance. The prospective implementation of this standard did not have a material impact on the financial statements of Eversource, CL&P, NSTAR Electric or PSNH for the year ended December 31, 2020.

On January 1, 2020, the Company prospectively adopted ASU 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The ASU modified fair value disclosure requirements. The standard includes new disclosure requirements for Level 3 unobservable inputs and eliminated the requirement to disclose certain information relating to transfers between levels. The modified disclosures are included in Note 1I, “Summary of Significant Accounting Policies - Fair Value Measurements,” and Note 4, “Derivative Instruments.”

The Company adopted ASU 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans – General, Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans as of January 1, 2020. The guidance eliminated certain disclosures about defined benefit plans, added new disclosures, and clarified other requirements. This guidance is effective for fiscal years ending after December 15, 2020. Adoption of this guidance did not have a material effect on our annual financial statement disclosures. The modified disclosures are included in Note 11A, “Employee Benefits - Pension Benefits and Postretirement Benefits Other Than Pension.”

D.     Impairment of Northern Pass Transmission
Northern Pass was Eversource's planned 1,090 MW HVDC transmission line that would have interconnected from the Québec-New Hampshire border to Franklin, New Hampshire and an associated alternating current radial transmission line between Franklin and Deerfield, New Hampshire. As a result of a final decision received on July 19, 2019 from the New Hampshire Supreme Court, whereby the court denied Northern Pass’ appeal and affirmed the NHSEC’s denial of Northern Pass’ siting application on NPT, Eversource concluded that construction of NPT was no longer probable and that there was no constructive path forward for the project. In 2019, Eversource terminated the project and permanently abandoned any further development.  As a result, substantially all of the capitalized project costs, which totaled $318 million, certain of which were subject to cost reimbursement agreements, were impaired.

Based on the conclusion that the construction of Northern Pass was no longer probable, Eversource recorded an impairment charge in 2019 for all of the project costs associated with Northern Pass, which were primarily engineering design, siting, permitting and legal costs, along with appropriate allowances for funds used during construction, and recognized a receivable for certain cost reimbursement agreements. Additionally, Eversource recorded an impairment charge associated with the land acquired to construct Northern Pass in order to recognize the land at its estimated fair value based on assessed values and transaction costs. In total, this resulted in a pre-tax impairment charge of $239.6 million within Operating Income on the statement of income for the year ended December 31, 2019 and was reflected in the Electric Transmission segment. The after-tax impact of the impairment charge was $204.4 million, or $0.64 per share, after giving effect to the estimated fair value of the related land, reimbursement agreements, and the impact of expected income tax benefits associated with the impairment charge. As a result of the decision to terminate the NPT project and permanently abandon any further development, Eversource does not expect any future cash expenditures associated with this project.

E.     Cash Equivalents
Cash includes cash on hand. At the end of each reporting period, any overdraft amounts are reclassified from Cash to Accounts Payable on the balance sheets. Cash Equivalents include short-term cash investments that are highly liquid in nature and have original maturities of three months or less.  

F.D.     Allowance for Uncollectible Accounts
Receivables, Net on the balance sheets primarily includes trade receivables from retail customers and customers related to wholesale transmission contracts, wholesale market sales, sales of RECs, and property rentals. Receivables, Net also includes customer receivables for the purchase of electricity from a competitive third party supplier, the current portion of customer energy efficiency loans, property damage receivables and other miscellaneous receivables. There is no material concentration of receivables.

Receivables are recorded at amortized cost, net of a credit loss provision (or allowance for uncollectible accounts).

Receivables are presented net of expected credit losses at estimated net realizable value by maintaining an allowance for uncollectible accounts. Effective January 1, 2020, the The current expected credit loss (CECL) model wasis applied to receivables for purposes of calculating the allowance for uncollectible accounts. This model is based on expected losses and results in the recognition of estimated expected credit losses, including uncollectible amounts for both billed and unbilled revenues, over the life of the receivable at the time a receivable is recorded.

Receivables, net of reserves, increased $206.5 million ($58.3 million at CL&P, $56.3 million at NSTAR Electric, and $20.0 million at PSNH) in 2020, as compared to 2019, due primarily to an increase in delinquent receivables from customers attributable to the moratorium on disconnections and the economic slowdown resulting from the COVID-19 pandemic. Receivables, net of reserves, also increased due to the addition of EGMA of $65.8 million as of December 31, 2020.

88


The allowance for uncollectible accounts is determined based upon a variety of judgments and factors, including the application ofan aging-based quantitative assessment that applies an estimated uncollectible percentage to each receivable aging category. Factors in determining credit loss include historical collection, write-off experience, analysis of delinquency statistics, and management's assessment of collectability from customers, including current economic conditions, customer payment trends, the impact on customer bills because of energy usage trends and changes in rates, flexible payment plans and financial hardship arrearage management programs offered to customers, reasonable forecasts, and expectations of future collectability and collection efforts. Management continuously assesses the collectability of receivables and adjusts estimates based on actual experience and future expectations based on economic indicators,conditions, collection efforts and other factors. Management also monitors the aging analysis of receivables to determine if there are changes in the collections of accounts receivable. Receivable balances are written off against the allowance for uncollectible accounts when the customer accounts are no longer in service and these balances are deemed to be uncollectible.

As of December 31, 2020, management evaluated the adequacy of the allowance for uncollectible accounts in light of the COVID-19 pandemic and the related economic downturn. This evaluation included an analysis of collection and customer payment trends, economic conditions, delinquency statistics, aging-based quantitative assessments, the impact on residential customer bills because of energy usage and change in rates, flexible payment plans and financial hardship arrearage management programs being offered to customers, and COVID-19 developments, including any potential federal governmental pandemic relief programs and the expansion of unemployment benefit initiatives, which help to mitigate the potential for increasing customer account delinquencies. Additionally, management considered past economic declines and corresponding uncollectible reserves as part of the current assessment. This evaluation has shown that our operating companies have experienced an increase in aged receivables and some lower cash collections from customers because of the moratorium on disconnections and the economic slowdown resulting from the COVID-19 pandemic. Based upon the evaluation performed, for the year ended December 31, 2020, management increased the allowance for uncollectible accounts for amounts incurred as a result of COVID-19 by $31.5 million for Eversource ($2.8 million for CL&P, $11.0 million for NSTAR Electric, $2.3 million for PSNH and $15.4 million at our natural gas businesses). These COVID-19 related uncollectible amounts were deferred either as incremental regulatory costs or deferred through existing regulatory tracking mechanisms that recover uncollectible energy supply costs, as management believes it is probable that these costs will ultimately be recovered from customers in rates.

Management concluded that the reserve balance as of December 31, 20202023 adequately reflected the collection risk and net realizable value for Eversource’sits receivables. Management will continue to evaluate the adequacy of the uncollectible allowance in future reporting periods based on an ongoing assessment of accounts receivable collections, delinquency statistics, and analysis of aging-based quantitative assessments.

The PURA allows CL&P and Yankee Gas to accelerate the recovery of accounts receivable balances attributable to qualified customers under financial or medical duress (uncollectible hardship accounts receivable) outstanding for greater than 180 days and 90 days, respectively.  The DPU allows NSTAR Electric, and NSTAR Gas and EGMA to recover in rates amounts associated with certain uncollectible hardship accounts receivable. Management also believes that uncollectible hardship accounts receivable at EGMA will be recoverable in future rates. These uncollectible hardship customer account balances are included in Regulatory Assets or Other Long-Term Assets on the balance sheets. Hardship customers are protected from shut-off in certain circumstances, and historical collection experience has reflected a higher default risk as compared to the rest of the receivable population. As a result of the adoption of ASU 2016-13, management aligned the allowance for uncollectible hardship accounts across all regulatory jurisdictions, usingManagement uses a higher credit risk profile for this pool of trade receivables as compared to non-hardship receivables. Implementation impacts of the accounting standard on the allowance for uncollectible hardship accounts are reflected in the rollforward of the uncollectible allowance in the table below. The allowance for uncollectible hardship accounts is included in the total uncollectible allowance balance.

Amounts include uncollectible costs for hardship accounts and other customer receivables, including uncollectible amounts related to uncollectible energy supply costs and COVID-19. The increase in the allowance for uncollectible hardship accounts in both 2023 and 2022 at Eversource and CL&P primarily relates to increased customer enrollment in disconnection prevention programs in Connecticut.

G.(2)    In connection with PSNH’s pole purchase agreement on May 1, 2023, the purchase price included the forgiveness of previously reserved receivables for reimbursement of operation and maintenance and vegetation management costs.

E.    Transfer of Energy Efficiency Loans

I.G.     Fair Value Measurements
Fair value measurement guidance is applied to derivative contracts that are not elected or designated as "normal purchases" or "normal sales" (normal) and to the marketable securities held in trusts. Fair value measurement guidance is also applied to valuations of the investments used to calculate the funded status of pension and PBOP plans, the nonrecurring fair value measurements of nonfinancial assets such as goodwill, long-lived assets, equity method investments, and AROs, and in the valuation of the acquisition of CMA in 2020.business combinations and asset acquisitions. The fair value measurement guidance was also applied in estimating the fair value of preferred stock, long-term debt and RRBs.
93



Fair Value Hierarchy:  In measuring fair value, Eversource uses observable market data when available in order to minimize the use of unobservable inputs.  Inputs used in fair value measurements are categorized into three fair value hierarchy levels for disclosure purposes.  The entire fair value measurement is categorized based on the lowest level of input that is significant to the fair value measurement.  Eversource evaluates the classification of assets and liabilities measured at fair value on a quarterly basis.  

The levels of the fair value hierarchy are described below:

Level 1 - Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities as of the reporting date.  Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.  

Level 2 - Inputs are quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs are observable.

Level 3 - Quoted market prices are not available.  Fair value is derived from valuation techniques in which one or more significant inputs or assumptions are unobservable.  Where possible, valuation techniques incorporate observable market inputs that can be validated to external sources such as industry exchanges, including prices of energy and energy-related products.  

Uncategorized - Investments that are measured at net asset value are not categorized within the fair value hierarchy.

Determination of Fair Value:  The valuation techniques and inputs used in Eversource's fair value measurements are described in Note 4, "Derivative Instruments," Note 5, "Marketable Securities," Note 6, "Investments in Unconsolidated Affiliates," Note 7, "Asset Retirement Obligations," Note 11A, "Employee Benefits – Pension Benefits and Postretirement Benefits Other Than Pension," Note 15, "Fair Value of Financial Instruments," Note 24, "Acquisition of Assets of Columbia Gas of Massachusetts," and Note 25,24, “Goodwill,” to the financial statements.

J.H.     Derivative Accounting
Many of the electric and natural gas companies' contracts for the purchase and sale of energy or energy-related products are derivatives.  The accounting treatment for energy contracts entered into varies and depends on the intended use of the particular contract and on whether or not the contract is a derivative.  

The application of derivative accounting is complex and requires management judgment in the following respects: identification of derivatives and embedded derivatives, election and designation of a contract as normal, and determination of the fair value of derivative contracts.  All of these judgments can have a significant impact on the financial statements.  The judgment applied in the election of a contract as normal (and resulting accrual accounting) includes the conclusion that it is probable at the inception of the contract and throughout its term that it will result in physical delivery of the underlying product and that the quantities will be used or sold by the business in the normal course of business.  If facts and circumstances change and management can no longer support this conclusion, then a contract cannot be considered normal, accrual accounting is terminated, and fair value accounting is applied prospectively.  

The fair value of derivative contracts is based upon the contract terms and conditions and the underlying market price or fair value per unit.  When quantities are not specified in the contract, the Company determines whether the contract has a determinable quantity by using amounts referenced in default provisions and other relevant sections of the contract.  The fair value of derivative assets and liabilities with the same counterparty are offset and recorded as a net derivative asset or liability on the balance sheets.  

Regulatory assets or regulatory liabilities are recorded to offset the fair values of these derivative contracts related to energy and energy-related products, as contract settlements are recovered from, or refunded to, customers in future rates. All changes in the fair value of these derivative contracts are recorded as regulatory assets or liabilities and do not impact net income.

For further information regarding derivative contracts, see Note 4, "Derivative Instruments," to the financial statements.

L.J.     Allowance for Funds Used During Construction
AFUDC represents the cost of borrowed and equity funds used to finance construction and is included in the cost of the electric, natural gas and water companies' utility plant on the balance sheet.  The portion of AFUDC attributable to borrowed funds is recorded as a reduction of Interest Expense, and the AFUDC related to equity funds is recorded as Other Income, Net on the statements of income.  AFUDC costs are recovered from customers over the service life of the related plant in the form of increased revenue collected as a result of higher depreciation expense.

The average AFUDC rate is based on a FERC-prescribed formula using the cost of a company's short-term financings and capitalization (preferred stock, long-term debt and common equity), as appropriate.  The average rate is applied to average eligible CWIP amounts to calculate AFUDC.

2.     REGULATORY ACCOUNTING

Eversource's utility companies are subject to rate regulation that is based on cost recovery and meets the criteria for application of accounting guidance for rate-regulated operations, which considers the effect of regulation on the timing of the recognition of certain revenues and expenses. The regulated companies' financial statements reflect the effects of the rate-making process.  The rates charged to the customers of Eversource's regulated companies are designed to collect each company's costs to provide service, plus a return on investment.  

The application of accounting guidance for rate-regulated enterprises results in recording regulatory assets and liabilities.  Regulatory assets represent the deferral of incurred costs that are probable of future recovery in customer rates.  Regulatory assets are amortized as the incurred costs are recovered through customer rates.  Regulatory liabilities represent either revenues received from customers to fund expected costs that have not yet been incurred or probable future refunds to customers.

Management believes it is probable that each of the regulated companies will recover its respective investments in long-lived assets and the regulatory assets that have been recorded.  If management were to determine that it could no longer apply the accounting guidance applicable to rate-regulated enterprises, or if management could not conclude it is probable that costs would be recovered from customers in future rates, the applicable costs would be charged to net income in the period in which the determination is made.

Storm Costs, Net: The storm cost deferrals relate to costs incurred for storm events at CL&P, NSTAR Electric and PSNH that each company expects to recover from customers.  A storm must meet certain criteria to qualify for deferral and recovery with the criteria specific to each state jurisdiction and utility company. Once a storm qualifies for recovery, all qualifying expenses incurred during storm restoration efforts are deferred and recovered from customers. Costs for storms that do not meet the specific criteria are expensed as incurred. In addition to storm restoration costs, CL&P and PSNH are each allowed to recover pre-staging storm costs. Management believes all storm costs deferred were prudently incurred and meet the criteria for specific cost recovery in Connecticut, Massachusetts and New Hampshire, and that recovery from customers is probable through the applicable regulatory recovery processes. Each electric utility company either recovers a carrying charge on its deferred storm cost regulatory asset balance or the regulatory asset balance is included in rate base.

Multiple tropical and severe storms over the past several years have caused extensive damage to Eversource’s electric distribution systems resulting in significant numbers and durations of customer outages, along with significant pre-staging costs. Storms in 2023 that qualified for future recovery resulted in deferred storm restoration costs and pre-staging costs totaling $542 million at Eversource, including $178 million at CL&P, $192 million at NSTAR Electric, and $172 million at PSNH. Management believes that all of these storm costs were prudently incurred and meet the criteria for specific cost recovery. Of Eversource’s total deferred storm costs, $1.75 billion either have yet to be filed with the applicable regulatory commission, are pending regulatory approval, or are subject to prudency review (including $975 million at CL&P, $526 million at NSTAR Electric and $246 million at PSNH) as of December 31, 2023. These storm cost totals exclude storm funding amounts that are collected in rates, which are recorded as a reduction to the deferred storm cost regulatory asset balance.

CL&P, NSTAR Electric and PSNH are seeking approval of their deferred storm restoration costs through the applicable regulatory recovery process. As part of CL&P’s October 1, 2021 settlement agreement, CL&P agreed to freeze its current base distribution rates (including storm costs) until no earlier than January 1, 2024. On December 22, 2023, CL&P initiated a docket seeking a prudency review of approximately $634 million of catastrophic storm costs for twenty-four weather events from January 1, 2018 to December 31, 2021. In the filing, CL&P requested PURA establish a rate to collect $50 million annually from customers from the date of the final decision in this proceeding. This rate
97


would be effective until the next distribution rate case and would replenish the under-collected storm reserve and reduce future carrying charges for customers.

CL&P’s storm events include the August 4, 2020 Tropical Storm Isaias, which resulted in deferred storm restoration costs of approximately $232 million at CL&P as of December 31, 2023. Although in 2021 PURA found that CL&P’s performance in its preparation for, and response to, Tropical Storm Isaias fell below applicable performance standards in certain instances, CL&P believes it presented in its 2023 storm filing, credible evidence demonstrating there is no reasonably close causal connection between the alleged sub-standard performance and the storm costs incurred. While it is possible that some amount of storm costs may be disallowed by PURA, any such amount cannot be estimated at this time. CL&P continues to believe that these storm restoration costs associated with Tropical Storm Isaias were prudently incurred and meet the criteria for cost recovery; and as a result, management does not expect the storm cost review by PURA to have a material impact on the financial position or results of operations of CL&P.

Regulatory Tracking Mechanisms:The regulated companies' approved rates are designed to recover costs incurred to provide service to customers. The regulated companies recover certain of their costs on a fully-reconciling basis through regulatory commission-approved tracking mechanisms. The differences between the costs incurred (or the rate recovery allowed) and the actual revenues are recorded as regulatory assets (for undercollections) or as regulatory liabilities (for overcollections) to be included in future customer rates each year.  Carrying charges are recovered in rates on all material regulatory tracking mechanisms.

The electric and natural gas distribution companies recover, on a fully reconciling basis, the costs associated with the procurement of energy and natural gas supply, electric transmission related costs from FERC-approved transmission tariffs, energy efficiency programs, low income assistance programs, certain uncollectible accounts receivable for hardship customers, restructuring and stranded costs as a result of deregulation (including securitized RRB charges), certain capital tracking mechanisms for infrastructure improvements, and additionally for the Massachusetts utilities, pension and PBOP benefits, net metering for distributed generation, and solar-related programs.

CL&P, NSTAR Electric, Yankee Gas, NSTAR Gas, EGMA and the Aquarion Water Company of Connecticut each have a regulatory commission approved revenue decoupling mechanism. Distribution revenues are decoupled from customer sales volumes, where applicable, which breaks the relationship between sales volumes and revenues.  Each company reconciles its annual base distribution rate recovery amount to the pre-established levels of baseline distribution delivery service revenues. Any difference between the allowed level of distribution revenue and the actual amount realized during a 12-month period is adjusted through rates in the following period. 

Benefit Costs:   Deferred benefit costs represent unrecognized actuarial losses and gains and unrecognized prior service costs and credits attributable to Eversource's Pension, SERP and PBOP Plans are accounted for in accordance with accounting guidance on defined benefit pension and other PBOP plans.Plans. The liability (or asset) recorded by the regulated companies to recognizerecord actuarial losses and gains and prior service costs and credits arising at the December 31st remeasurement date of the funded status of their retireethe benefit plans is offset byas a regulatory asset (or offset by aor regulatory liability in the case of a benefit plan asset) in lieu of a charge to Accumulated Other Comprehensive Income/(Loss), reflecting ultimate recovery from customers through rates.  The regulatory asset (oror regulatory liability)liability is amortized aswith the recognition of actuarial gainslosses and lossesgains and prior service cost are amortizedcosts and credits to net periodic benefit cost forexpense/income over the pension and PBOP plans.  All amounts are remeasured annually.estimated average future employee service period using the corridor approach.  Regulatory accounting is also applied to the portions of Eversource's service company costs that support the regulated companies, as these amounts are also recoverable.  As these regulatory assets or regulatory liabilities do not represent a cash outlay for the regulated companies, no carrying charge is recovered from customers. See Note 11A, "Employee Benefits - Pension Benefits and Postretirement Benefits Other Than Pension," for further information on regulatory benefit plan amounts recognizedarising and amortized during the year.

Eversource, CL&P, NSTAR Electric, and PSNH recover benefit costs related to their distribution and transmission operations from customers in rates as allowed by their applicable regulatory commissions.  NSTAR Electric, recoversNSTAR Gas and EGMA recover qualified pension and PBOP expenses related to itstheir distribution operations through a rate reconciling mechanism that fully tracks the change in net pension and PBOP expenses each year.  The electric transmission companies' rates provide for an annual true-up of estimated to actual costs, which include pension and PBOP expenses.

Income Taxes, Net:  The tax effect of temporary book-tax differences (differences between the periods in which transactions affect income in the financial statements and the periods in which they affect the determination of taxable income, including those differences relating to uncertain tax positions) is accounted for in accordance with the rate-making treatment of the applicable regulatory commissions and accounting guidance for income taxes.  Differences in income taxes between the accounting guidance and the rate-making treatment of the applicable regulatory commissions are recorded as regulatory assets.  As these assets are offset by deferred income tax liabilities, no carrying charge is collected.  The amortization period of these assets varies depending on the nature and/or remaining life of the underlying assets and liabilities.  For further information regarding income taxes, see Note 12, "Income Taxes," to the financial statements.  

Securitized Stranded Costs: In 2018, a subsidiary of PSNH issued $635.7 million of securitized RRBs to finance PSNH's unrecovered remaining costs associated with the divestiture of its generation assets. Securitized regulatory assets, which are not earning an equity return, are being recovered over the amortization period of the associated RRBs. The PSNH RRBs are expected to be repaid by February 1, 2033. For further information, see Note 10, "Rate Reduction Bonds and Variable Interest Entities.Entities," to the financial statements.

Goodwill-related:  The goodwill regulatory asset originated from a 1999 transaction, and the DPU allowed its recovery in NSTAR Electric and NSTAR Gas rates.  This regulatory asset is currently being amortized and recovered from customers in rates without a carrying charge over a 40-year period, and as of December 31, 2023, there were 16 years of amortization remaining.

Storm Restoration Costs, Net:Asset Retirement Obligations: The storm restoration cost deferrals relate to costs incurred for storm events at CL&P, NSTAR Electric and PSNH that each company expects to recover from customers.  A storm must meet certain criteria to qualify for deferral and recoveryassociated with the criteria specific to each state jurisdiction and utility company. Once a storm qualifies for recovery, all qualifying expenses incurred during storm restoration efforts are deferred and recovered from customers. Costs for storms that do not meet the specific criteria are expensed as incurred. In addition to storm restoration costs, CL&P and PSNH are each allowed to recover pre-staging storm costs. Management believes storm restoration costs deferred were prudently incurred and meet the criteria for specific cost recovery in Connecticut, Massachusetts and New Hampshire, and that recovery from customers is probable through the applicable regulatory recovery processes. Each electric utility company either recovers a carrying charge on its deferred storm restoration cost regulatory asset balance or the regulatory asset balance is included in rate base. Of the total deferred storm restoration costs, $591 million is either pending regulatory approval or has yet to be filed with the applicable regulatory commission (including $390 million at CL&P, $166 million at NSTAR Electric and $35 million at PSNH).

Storm Event: On August 4, 2020, Tropical Storm Isaias caused catastrophic damage to our electric distribution system, which resulted in significant amounts and durations of customer outages, primarily in Connecticut. In terms of customer outages, this storm was onedepreciation of the worst in CL&P’s history. PURA has opened an investigation into CL&P's response to Tropical Storm Isaias.  PURA will also investigate the prudence of costs incurred by CL&P to restore service as part of its response.  CL&P is fully participating in PURA’s investigationsregulated companies' ARO assets and believes that these storm restoration costs were prudently incurred and meet the criteria for cost recovery.  As a result, management does not expect the storm costs to have a material impact on the results of operations of Eversource or CL&P.

Based on current estimates, the storm resulted in deferred storm restoration costs on our balance sheets of approximately $228 million at CL&P and $245 million at Eversource as of December 31, 2020. The estimated cost of restoration will change as additional cost information becomes available, final storm costs are deferred or capitalized, and post-storm restoration work is completed. The majority of incremental storm costs relate to third-party vendors that are external field crews needed to restore power and address municipal priorities. CL&P’s current estimate of total storm costs includes its projectionaccretion of the cost of such vendors, but that estimate will change as CL&P receives and examines all storm related invoices.

Regulatory Tracker Mechanisms:The regulated companies' approved rates are designed to recover costs incurred to provide service to customers. The regulated companies recover certain of their costs on a fully-reconciling basis through regulatory commission-approved tracking mechanisms. The differences between the costs incurred (or the rate recovery allowed) and the actual revenuesARO liabilities are recorded as regulatory assets (for undercollections) or asin accordance with regulatory accounting guidance. The regulated companies' ARO assets, regulatory assets, and ARO liabilities (for overcollections) to be included in future customer rates each year.  Carrying chargesoffset and are excluded from rate base. These costs are being recovered in rates on all material regulatory tracker mechanisms.

CL&P, NSTAR Electric and PSNH each recover, on a fully reconciling basis,over the costs associated with the procurement of energy, transmission related costs from FERC-approved transmission tariffs, energy efficiency programs, low income assistance programs, certain uncollectible accounts receivable for hardship customers, and restructuring and stranded costs as a result of deregulation (including securitized RRB charges), and additionally for the Massachusetts utilities, pension and PBOP benefits and net metering for distributed generation. Energy procurement costs at NSTAR Electric include the costs related to its solar power facilities.

CL&P, NSTAR Electric, Yankee Gas, NSTAR Gas and EGMA each have a regulatory commission approved revenue decoupling mechanism. Distribution revenues are decoupled from customer sales volumes, where applicable, which breaks the relationship between sales volumes and revenues.  Each company reconciles its annual base distribution rate recovery amount to the pre-established levels of baseline distribution delivery service revenues. Any difference between the allowed level of distribution revenue and the actual amount realized during a 12-month period is adjusted through rates in the following period. 

CL&P Rate Suspension: On July 31, 2020, PURA temporarily suspended its June 26, 2020 approval of certain delivery rate components effective July 1, 2020, and ordered CL&P to restore rates to those in effect as of June 30, 2020 in order to allow PURA time to reexamine the rates to ensure that CL&P is not over-collecting revenues in the short-term. Rates were adjusted effective August 1, 2020. On December 2, 2020, PURA issued a final decision in which it adjusted the timinglife of the annual rate adjustments for the Revenue Decoupling Mechanism Charge, the Transmission Adjustment Clause charge, the Non-Bypassable Federally Mandated Congestion Charge,underlying property, plant and the Electric System Improvements Tracker so that these rates take effect on May 1st of each year, as opposed to the current process of adjusting rates each January 1 and July 1. The temporary suspension of rates has resulted in a current period under-recovery of costs, which results in an increase to our regulatory assets, with no impact on the statement of income other than carrying charges, and a delay in the collection of our costs. This deferral is reflected within Regulatory Tracker Mechanisms in the table above.equipment.

Derivative Liabilities:  Regulatory assets are recorded as an offset to derivative liabilities and relate to the fair value of contracts used to purchase energy and energy-related products that will be recovered from customers in future rates.  These assets are excluded from rate base and are being recovered as the actual settlements occur over the duration of the contracts.  See Note 4, "Derivative Instruments," to the financial statements for further information on these contracts.

Goodwill-related:  The goodwill regulatory asset originated from a 1999 transaction, and the DPU allowed its recovery in NSTAR Electric and NSTAR Gas rates.  This regulatory asset is currently being amortized and recovered from customers in rates without a carrying charge over a 40-year period, and as of December 31, 2020, there were 19 years of amortization remaining.

Asset Retirement Obligations: The costs associated with the depreciation of the regulated companies' ARO assets and accretion of the ARO liabilities are recorded as regulatory assets in accordance with regulatory accounting guidance. The regulated companies' ARO assets, regulatory assets, and ARO liabilities offset and are excluded from rate base. These costs are being recovered over the life of the underlying property, plant and equipment.

Other Regulatory Assets:  Other Regulatory Assets primarily include environmental remediation costs, certain uncollectible accounts receivable for hardship customers, certain exogenous property taxes and merger-related costs allowed for recovery, contractual obligations associated with the spent nuclear fuel storage costs of the CYAPC, YAEC and MYAPC decommissioned nuclear power facilities, environmental remediationwater tank painting costs, losses associated with the reacquisition or redemption of long-term debt, certain uncollectible accounts receivable for hardshipremoval costs incurred that exceed amounts collected from customers, certain merger-related costs allowed for recovery, water tank painting costs, and various other items.

Regulatory Costs in Other Long-Term Assets:  Eversource's regulated companies had $196.9$241.7 million (including $84.1$166.7 million for CL&P, $69.8$21.9 million for NSTAR Electric and $4.3$1.2 million for PSNH) and $146.0$210.8 million (including $51.8$135.9 million for CL&P, $55.7$19.8 million for NSTAR Electric and $18.0$1.0 million for PSNH) of additional regulatory costs not yet specifically approved as of December 31, 20202023 and 2019,2022, respectively, that were included in long-term assetsOther Long-Term Assets on the balance sheets.  These amounts represent incurred costs for which recovery has not yet been specifically approvedwill be reclassified to Regulatory Assets upon approval by the applicable regulatory agency.  However, basedBased on regulatory policies or past precedent on similar costs, management believes it is probable that these costs will ultimately be approved and recovered from customers in rates. As of December 31, 2020, net incremental2023 and 2022, these regulatory costs as a resultincluded $82.1 million (including $64.0 million for CL&P and $7.3 million for NSTAR Electric) and $64.0 million (including $52.8 million for CL&P and $3.5 million for NSTAR Electric), respectively, of COVID-19 deferred by Eversource totaled $24.0 million, of which $15.8 million ($3.0 million at CL&P, $6.8 million at NSTAR Electric and $0.6 million at PSNH) was related to non-tracked uncollectible expense and $8.2 million ($1.7 million at CL&P, $5.1 million at NSTAR Electric and $0.5 million at PSNH) related to facilities and fleet cleaning, sanitizing costs and supplies for personal protective equipment.hardship costs.

Equity Return on Regulatory Assets:  For rate-making purposes, the regulated companies recover the carrying costs related to their regulatory assets.  For certain regulatory assets, the carrying cost recovered includes an equity return component.  This equity return which is not recorded on the balance sheets, totaled $0.2sheets. The equity return for PSNH was $10.2 million and $0.5$4.1 million for CL&P as of December 31, 20202023 and 2019, respectively, and $5.1 million and $6.5 million for PSNH as of December 31, 2020 and 2019,2022, respectively. These carrying costs will be recovered from customers in future rates.

EDIT due to Tax Cuts and Jobs Act of 2017: Pursuant to the Tax Cuts and Jobs Act of 2017, Eversource had remeasured its existing deferred federal income tax balances to reflect the decrease in the U.S. federal corporate income tax rate from 35 percent to 21 percent. The remeasurement resulted in provisional regulated excess accumulated deferred income tax (excess ADIT or EDIT) liabilities that will benefit our customers in future periods and were recognized as regulatory liabilities on the balance sheet. EDIT liabilities related to property, plant, and equipment are subject to IRS normalization rules and will be returned to customers using the same timing as the remaining useful lives of the underlying assets that gave rise to the ADIT liabilities.

Eversource's regulated companies (except for the Connecticut water business) are in the process of or will be, refunding the EDIT liabilities to customers based on orders issued by applicable state and federal regulatory commissions. For PSNH (effective January 1, 2021), CL&P (effective May 1, 2019) and Yankee Gas (effective November 15, 2018), the refund of EDIT liabilities was incorporated into base distribution rates. For NSTAR Electric (effective January 1, 2019) and NSTAR Gas (effective February 1, 2019), the refund of EDIT liabilities occurred in rates through a new reconciling factor. The Connecticut water business has not yet begun to reflect the refund of EDIT in distribution rates. See "Recent Regulatory Developments" below for information on the PSNH 2020 rate settlement agreement and the impact on the EDIT balance.

Cost of Removal:  Eversource's regulated companies currently recover amounts in rates for future costs of removal of plant assets over the lives of the assets.  The estimated cost to remove utility assets from service is recognized as a component of depreciation expense, and the cumulative amount collected from customers but not yet expended is recognized as a regulatory liability.  Expended removal costs that exceed amounts collected from customers are recognized as regulatory assets, as they are probable of recovery in future rates.

Deferred Portion of Non-Service Income Components of Pension, SERP and PBOP:  Regulatory liabilities were recorded for the deferred portion of the non-service related components of net periodic benefit expense/(income) for the Pension, SERP and PBOP Plans. These regulatory liabilities will be amortized over the remaining useful lives of the various classes of utility property, plant and equipment.

99


AFUDC - Transmission:  Regulatory liabilities were recorded by CL&P and NSTAR Electric for AFUDC accrued on certain reliability-related transmission projects to reflect local rate base recovery.  These regulatory liabilities will be amortized over the depreciable life of the related transmission assets.

Other Regulatory Liabilities:Other Regulatory Liabilities primarily include EGMA’s acquired regulatory liability as a result of the 2020 DPU-approved rate settlement agreement and the CMA asset acquisition on October 9, 2020, and various other items.

FERC ROE Complaints:Complaints:  As of December 31, 2020,2023 and 2022, Eversource has a reserve established for the second ROE complaint period in the pending FERC ROE complaint proceedings, which was recorded as a regulatory liability and is reflected within Regulatory TrackerTracking Mechanisms in the table above.  The cumulative pre-tax reserve (excluding interest) as of December 31, 20202023 and 2022 totaled $39.1 million for Eversource (including $21.4 million for CL&P, $14.6 million for NSTAR Electric and $3.1 million for PSNH). See Note 13E, "Commitments and Contingencies – FERC ROE Complaints," for further information on developments in the pending ROE complaint proceedings.

96Regulatory Developments:


Recent Regulatory Developments2022 CL&P Rate Relief Plan:: On November 28, 2022, Governor Lamont, DEEP, Office of Consumer Counsel, and CL&P jointly developed a rate relief plan for electric customers for the winter peak season of January 1, 2023 through April 30, 2023. On December 16, 2022, PURA approved the rate relief plan. As part of the rate relief plan, CL&P reduced the Non-Bypassable Federally Mandated Congestion Charge (NBFMCC) rate effective January 1, 2023 to provide customers with an average $10 monthly bill credit from January through April 2023. This rate reduction accelerated the return to customers of net revenues generated by long-term state-approved energy contracts with the Millstone and Seabrook nuclear power plants of approximately $90 million. The rate relief plan also included instituting a temporary, flat monthly discount for qualifying low-income hardship customers effective January 1, 2023. This flat-rate credit will continue until a new low-income discount rate that was approved by PURA in an October 19, 2022 decision is implemented in 2024. These aspects of the rate relief plan do not impact CL&P’s earnings but do impact its future cash flows. Also as part of the rate relief plan, CL&P committed to contribute $10 million to an energy assistance program for qualifying hardship customers, which was distributed as a bill credit to those customers during 2023. CL&P recorded a current liability of $10 million on the balance sheet and a charge to expense on the statement of income for the year ended December 31, 2022 associated with the customer assistance program.

PSNH2022 NSTAR Electric Distribution Rates:Rate Case: On December 15, 2020,November 30, 2022, the NHPUC approved an October 9, 2020 settlement agreement on permanent rates between PSNHDPU issued its decision in the NSTAR Electric distribution rate case and all parties to the proceeding. The NHPUC approved a permanentbase distribution rate increase of $45.0$64 million effective January 1, 2021, inclusive2023. The DPU approved a renewal of the temporaryPBR plan originally authorized in its previous rate increase previously approved. PSNH wascase for a five-year term, with a corresponding stay out provision. The PBR plan term has the possibility of a five-year extension. The PBR mechanism allows for an annual adjustment to base distribution rates for inflation and exogenous events. The DPU also permitted three step increases, effectiveallowed for adjustments to the PBR mechanism for the recovery of future capital additions based on a historical five-year average of total capital additions, beginning with the January 1, 2021, August 1, 2021, and August 1, 2022, to reflect plant additions in calendar years 2019, 2020 and 2021, respectively. On December 23, 2020, the NHPUC approved the first step adjustment for 2019 plant in service to recover a revenue requirement of $10.6 million, subject to reconciliation after completion of an audit, effective January 1, 2021.2024 PBR adjustment. The settlement agreement also establisheddecision allows an authorized regulatory ROE of 9.39.80 percent withon a 54.4 percent common equity ratio in PSNH’s capital structure and provided for a new tracker to recover regulatory assessments, vegetation management costs, property tax costs, and lost distribution revenue attributable to net metering. In addition, base distribution rates were adjusted to reflect the refund of EDIT from the Tax Cuts and Jobs Act of 2017.including 53.2 percent equity.

The settlement agreementAmong other items, the DPU approved an increase to the annual storm fund contribution collected through base distribution rates from $10 million to $31 million, and allowed for the effectrecovery of the permanent rate increase to be extended backstorm threshold costs of $1.3 million per storm event subsequent to the temporary rate period. In lieueighth storm in a calendar year (six recovered in base rates plus two additional storms). The DPU approved cost recovery of a customer rate increase for this recoupment of revenue, the NHPUC directed a portion of NSTAR Electric’s outstanding storm costs beginning on January 1, 2023 and January 1, 2024, subject to reconciliation from future prudency reviews. In a subsequent compliance filing, the total EDIT regulatory liabilityDPU allowed recovery to offset bill impacts to customers. The impact of the settlement agreement resulted in an after-tax benefit to earnings in 2020 of $11.0 million at Eversource ($7.2 million at PSNH), due primarily to the reconciliation of permanent rates back to the temporary rate period resultingcommence for outstanding storm costs occurring between 2018 and 2022 and interest in a reductiontotal of the EDIT regulatory liability, which reduced Income Tax Expense on the statement$162.1 million over a five-year period starting January 1, 2023. In addition, NSTAR Electric will begin to recover 2021 exogenous storms and interest in a total of income, and$220.9 million over a five-year period beginning January 1, 2024. The DPU also approved the allowed recovery of previously expensed costs. The earnings impact was partially offset by the negative impacthistorical exogenous property taxes of $30.8 million incurred from the over-refunding of the change in the 2018 federal corporate income tax rate as2020 through 2022 over a two-year period and $8.3 million incurred from 2012 through 2015 over a five-year period effective January 1, 2023. As a result of the Tax Cuts and Jobs Act of 2017 that was reflected in temporary rates, which reduced Operating Revenuesthis decision, these deferred property taxes were reclassified from Other Long-Term Assets to Regulatory Assets on the statement of income.NSTAR Electric December 31, 2022 balance sheet.

PSNH Generation Asset Divestiture-Related Costs2023 NSTAR Electric Distribution Rates: On MayNSTAR Electric submitted its first annual PBR Adjustment filing on September 15, 2020,2023 and on December 26, 2023, the NHPUC Audit Staff issuedDPU approved a final report$104.9 million increase to base distribution rates effective January 1, 2024. The base distribution rate increase was comprised of a $50.6 million inflation-based adjustment and a $54.3 million K-bar adjustment for capital additions based on the auditdifference between the historical five-year average of PSNH’s generation asset divestiture-related coststotal capital additions and resulting securitizedthe base capital revenue requirement.

2022 NSTAR Gas Distribution Rates: NSTAR Gas’ PBR mechanism allows for an annual adjustment to base distribution rates for inflation and stranded costs.exogenous events. NSTAR Gas submitted its second annual PBR Adjustment filing on September 15, 2022 and on October 31, 2022, the DPU approved a $21.7 million increase to base distribution rates for effect on November 1, 2022. The findings in the audit report as well as other aspectsincrease is inclusive of the divestiture process were further investigated by NHPUC Staff through the discovery phase, which was completed in July 2020. On September 30, 2020, PSNH filed a settlement agreement on the generation asset divestiture-related costs with the NHPUC Audit Staff.$4.5 million permanent increase related to exogenous property taxes and a $5.4 million increase related to an October 6, 2021 mitigation plan filing that delayed recovery of a portion of a base distribution rate increase originally scheduled to take effect November 1, 2021. The settlement agreement resolved all issues with respect to PSNH’s divestiture of its generating assets andDPU also approved the recovery of $12.0historical exogenous property taxes incurred from November 1, 2020 through October 31, 2022 of $8.2 million of divestiture-related costs incurred above the $635.7 million amount previously securitized. On December 17, 2020, the NHPUC approved the additional $12.0 million proposed in the settlement agreement to be recovered over a one-yeartwo-year period through the SCRC rate beginning Februarya separate reconciling mechanism effective November 1, 2021.2022. As a result of the settlement agreement, the $12.0 million of divestiture-related coststhis decision, these deferred property taxes were transferredreclassified from Other Long-Term Assets to Regulatory Assets on the Eversource and PSNH balance sheets as of December 31, 2020.2022 balance sheet.

2023 NSTAR Gas Rate CaseDistribution Rates:: On NSTAR Gas submitted its third annual PBR Adjustment filing on September 15, 2023 and on October 30, 2020,2023, the DPU approved a $25.4 million increase to base distribution rates, of which, $15.5 million was associated with a base rate increase of $23.0 million effective November 1, 2020, compared toadjustment and the original request of $38.0 million. NSTAR Gas' 2019 plant additions are allowed recovery beginningremainder for a prior period exogenous cost adjustment, for effect on November 1, 2021.  Thus, the reduced revenue requirement reflects the removal of this recovery, among other adjustments. The DPU also approved NSTAR Gas' proposal to continue its ongoing Gas System Enhancement Program (GSEP), the inclusion of GSEP investments since 2015 into base rates, and the implementation of a 10-year performance-based ratemaking plan, which includes an inflation-based adjustment mechanism to annual base distribution rates. The decision allows an authorized regulatory ROE of 9.9 percent on a capital structure including 54.77 percent equity. The decision also approves a geothermal pilot program. The impact of the rate case decision resulted in a pre-tax charge to earnings in 2020 of $2.7 million at NSTAR Gas, primarily due to certain plant-related disallowances.

EGMA Rate Settlement Agreement: On October 7, 2020, the DPU approved a rate settlement agreement, which approved the CMA asset acquisition as well as a rate stabilization plan, among other items. See Note 24, "Acquisition of Assets of Columbia Gas of Massachusetts" for further information.2023.

2022 EGMA Distribution Rates: As established in an October 7, 2020 EGMA Rate Settlement Agreement approved by the DPU, on September 16, 2022 EGMA filed for its second base distribution rate increase and on October 31, 2022, the DPU approved a $6.7 million increase to base distribution rates and a $3.3 million increase to the Tax Act Credit Factor for effect on November 1, 2022. The DPU also approved the recovery of historical exogenous property taxes incurred from November 1, 2020 through October 31, 2022 of $8.6 million over a two-year period through a separate reconciling mechanism effective November 1, 2022. EGMA will request recovery of incremental property taxes incurred after October 31, 2022 in future exogenous filings. As a result of this decision, these deferred property taxes were reclassified from Other Long-Term Assets to Regulatory Assets on the Eversource December 31, 2022 balance sheet.

2023 PSNH Pole Acquisition Approval: On November 18, 2022, the NHPUC issued a decision that approved a proposed purchase agreement between PSNH and Consolidated Communications, in which, PSNH would acquire both jointly-owned and solely-owned poles and pole assets. The NHPUC also authorized PSNH to recover certain expenses associated with the operation and maintenance of the transferred poles, pole inspections, and vegetation management expenses through a new cost recovery mechanism, the Pole Plant Adjustment Mechanism (PPAM), subject to consummation of the purchase agreement. The purchase agreement was finalized on May 1, 2023 for a purchase price of $23.3 million. Upon consummation of the purchase agreement, PSNH established a regulatory asset of $16.9 million for operation and maintenance expenses and vegetation management expenses associated with the purchased poles incurred from February 10, 2021 through April 30, 2023 that PSNH is authorized to collect through the PPAM regulatory tracking mechanism. The establishment of the PPAM regulatory asset resulted in a pre-tax benefit recorded in Amortization expense on the PSNH statement of income in 2023.

(1)These assets are primarily comprised of computer software, hardware and equipment at Eversource Service and buildings at The Rocky River Realty Company.

On October 9, 2020, Eversource completed the CMA asset acquisition. EGMA’s net plant assets of $1.20 billion are reflected in the natural gas distribution asset category as of December 31, 2020.

On July 31, 2020, Eversource sold its water system and treatment plant that supplies water to the towns of Hingham, Hull and North Cohasset to the town of Hingham, Massachusetts. Net property, plant and equipment of $63.9 million and goodwill of $23.6 million were included in determining the gain on sale. Proceeds from the sale were $110.5 million, with a pre-tax gain of $16.0 million (after-tax gain of $3.5 million) recognized within Operations and Maintenance Expense on the statement of income for the year ended December 31, 2020. The assets and liabilities associated with the sale of the business were previously reflected in the Water Distribution segment and reporting unit.

Depreciation:Depreciation of utility assets is calculated on a straight-line basis using composite rates based on the estimated remaining useful lives of the various classes of property (estimated useful life for PSNH distribution and the water utilities).  The composite rates, which are subject to approval by the appropriate state regulatory agency, include a cost of removal component, which is collected from customers over the lives of the plant assets and is recognized as a regulatory liability.  Depreciation rates are applied to property from the time it is placed in service.
101



Upon retirement from service, the cost of the utility asset is charged to the accumulated provision for depreciation.  The actual incurred removal costs are applied against the related regulatory liability.

4.     DERIVATIVE INSTRUMENTS

The electric and natural gas companies purchase and procure energy and energy-related products, which are subject to price volatility, for their customers.  The costs associated with supplying energy to customers are recoverable from customers in future rates.  These regulated companies manage the risks associated with the price volatility of energy and energy-related products through the use of derivative and non-derivative contracts.

Many of the derivative contracts meet the definition of, and are designated as, normal and qualify for accrual accounting under the applicable accounting guidance.  The costs and benefits of derivative contracts that meet the definition of normal are recognized in Operating Expenses on the statements of income as applicable, as electricity or natural gas is delivered.

Derivative contracts that are not designated as normal are recorded at fair value as current or long-term Derivative Assets or Derivative Liabilities on the balance sheets.  For the electric and natural gas companies, regulatory assets or regulatory liabilities are recorded to offset the fair values of derivatives, as contract settlement amounts are recovered from, or refunded to, customers in their respective energy supply rates.  

The gross fair values of derivative assets and liabilities with the same counterparty are offset and reported as net Derivative Assets or Derivative Liabilities, with current and long-term portions, on the balance sheets.  The following table presents the gross fair values of contracts, categorized by risk type, and the net amounts recorded as current or long-term derivative assets or liabilities:

Derivative Contracts at Fair Value with Offsetting Regulatory Amounts
Commodity Supply and Price Risk Management:  As required by regulation, CL&P, along with UI, has capacity-related contracts with generation facilities.  CL&P has a sharing agreement with UI, with 80 percent of the costs or benefits of each contract borne by or allocated to CL&P and 20 percent borne by or allocated to UI.  The combined capacities of these contracts as of December 31, 20202023 and 20192022 were 675682 MW and 676674 MW, respectively. The capacity contracts extend through 2026 and obligate both CL&P and UI to make or receive payments on a monthly basis to or from the generation facilities based on the difference between a set capacity price and the capacity market price received in the ISO-NE capacity markets.  In addition, CL&P had a contract to purchase 0.1 million MWh of energy per year through 2020.

As of December 31, 2020 and 2019, Eversource had New York Mercantile Exchange (NYMEX) financial contracts for natural gas futures in order to reduce variability associated with the price of 8.9 million and 9.6 million MMBtu of natural gas, respectively.

For the years ended December 31, 2020, 20192023, 2022 and 2018,2021, there were losses of $21.2$3.9 million, $20.7gains of $10.1 million and $25.0losses of $7.1 million, respectively, deferred as regulatory costs, which reflect the change in fair value associated with Eversource's derivative contracts.

Fair Value Measurements of Derivative Instruments
Derivative contracts classified as Level 2 in the fair value hierarchy relate to the financial contracts for natural gas futures.  Prices are obtained from broker quotes and are based on actual market activity.  The contracts are valued using NYMEX natural gas prices.  Valuations of these contracts also incorporate discount rates using the yield curve approach.  

The fair value of derivative contracts classified as Level 3 utilizes significantboth observable and unobservable inputs.  The fair value is modeled using income techniques, such as discounted cash flow valuations adjusted for assumptions related to exit price. Significant observable inputs for valuations of these contracts include energy and energy-related product prices in future years for which quoted prices in an active market exist.  Fair value measurements categorized in Level 3 of the fair value hierarchy are prepared by individuals with expertise in valuation techniques, pricing of energy and energy-related products, and accounting requirements.  The future capacity prices for periods that are not quoted in an active market or established at auction are based on available market data and are escalated based on estimates of inflation in order to address the full term of the contract.  

Valuations of derivative contracts using a discounted cash flow methodology include assumptions regarding the timing and likelihood of scheduled capacity payments and also reflect non-performance risk, including credit, using the default probability approach based on the counterparty'scounterparty’s credit rating for assets and the Company'sCompany’s credit rating for liabilities. Significant observable inputs for valuations of these contracts include energy-related product prices in future years for which quoted prices in an active market exist. Valuations incorporate estimates of premiums or discounts that would be required by a market participant to arrive at an exit price, using historical market transactions adjusted for the terms of the contract.  

The following is a summaryFair value measurements were prepared by individuals with expertise in valuation techniques, pricing of energy-related products, and accounting requirements. All derivative contracts were classified as Level 2 in the fair value hierarchy as of December 31, 2023, and were classified as Level 3 derivative contracts and the rangeas of the significant unobservable inputs utilized in the valuations over the duration of the contracts:

Exit price premiums of 7.1 percent through 11.4 percent, or a weighted average of 10.3 percent, are alsounobservable inputs applied to these contracts and reflect the uncertainty and illiquidity premiums that would be required based on the most recent market activity available for similar type contracts. The risk premium was weighted by the relative fair value of the net derivative instruments.As of December 31, 2022, these exit price premiums were a Level 3 significant unobservable input and ranged from 2.9 percent through 7.1 percent, or a weighted average of 6.1 percent. As of December 31, 2023, exit price premiums are no longer considered significant in the valuation of the derivative contracts.

As of December 31, 2022, Level 3 significant unobservable inputs also utilized in the valuation of CL&P’s capacity-related contracts included forward reserve prices of $0.44 per kW-Month through $0.50 per kW-Month, or a weighted average of $0.47 per kW-Month, over the period 2023 through 2024. As of December 31, 2023, these forward reserve price inputs are now observable.

Significant increases or decreases in future capacity or forward reserve prices in isolation would decrease or increase, respectively, the fair value of the derivative liability.  Any increases in risk premiums would increase the fair value of the derivative liability.  Changes in these fair values are recorded as a regulatory asset or liability and do not impact net income.

For the years ended December 31, 2020, 20192023, 2022 and 2018,2021, Eversource had equity in earnings net of impairment, of unconsolidated affiliates of $14.2$15.5 million, $42.2$22.9 million, and $3.8$14.2 million, respectively. Eversource received dividends from its equity method investees (excluding proceeds received from sale or liquidation of $21.8investments) of $20.1 million, $48.9$26.2 million, and $22.3$21.6 million, respectively, for the years ended December 31, 2020, 20192023, 2022 and 2018.2021.

Investments in affiliates where Eversource has the ability to exercise significant influence, but not control, over an investee are initially recognized as an equity method investment at cost. Any differences between the cost of an investment and the amount of underlying equity in net assets of an investee are considered basis differences, and are determined based upon the estimated fair values of the investee's identifiable assets and liabilities. The carrying amount of Eversource’s offshore wind investments, exceededwhich include 50 percent ownership interests in two offshore wind joint ventures and a 100 percent ownership in a tax equity investment, do not represent controlling financial interests. Eversource’s offshore wind investments, its share of underlyingthe natural gas pipeline and other investments included in the table above are accounted for under the equity in net assets by $264.1 million and $240.3 million, respectively, as of December 31, 2020 and 2019. As of December 31, 2020, these basis differences are primarily comprised of $168.3 million of equity method goodwill that is not being amortized, intangible assets for PPAs, which will be amortized over the term of the PPAs, and capitalized interest.method.

Offshore Wind Business: Eversource'sEversource’s offshore wind business includes 50 percent ownership interests in each of North East Offshore and Bay State Wind,South Fork Class B Member, LLC, which togethercollectively hold PPAs and contracts forthree offshore wind projects. North East Offshore holds the Revolution Wind project and the Sunrise Wind project. South Fork Class B Member, LLC holds the South Fork Wind and Sunriseproject. Eversource’s offshore wind business also includes a noncontrolling tax equity investment in South Fork Wind projects, as well as offshore leases through BOEM. Eversource'sa 100 percent ownership in South Fork Wind Holdings, LLC Class A shares. The offshore wind projects are being developed and constructed through a joint and equal partnershippartnerships with Ørsted. On February 8, 2019, Eversource and Ørsted entered into an equal partnership to acquire key offshore wind assets in the Northeast. Eversource has a 50 percent ownership interest in North East Offshore, which holds the Revolution Wind and South Fork Wind projects, as well as a 257 square-mile lease off the coasts of Massachusetts and Rhode Island. Eversource also has a 50 percent ownership interest in Bay State Wind, which holds the Sunrise Wind project. Bay State Wind's separate 300-square-mile ocean lease is located approximately 25 miles south of the coast of Massachusetts adjacent to the North East Offshore area.

Impairment
In September of Equity Method Investments: 2023, Eversource made a contribution of $528 million using the proceeds from the lease area sale to invest in a tax equity interest for South Fork Wind. South Fork Wind was restructured as a tax equity investment, with Eversource purchasing 100 percent ownership of a new Class A tax equity membership interest. As a result of this investment, Eversource expects to receive investment tax credits after the turbines are placed in service for South Fork Wind and meet the requirements to qualify for the ITC. These credits will be utilized to reduce Eversource’s federal tax liability or generate tax refunds over the next 24 months. All of South Fork Wind’s twelve turbines are expected to be installed and placed into service by the end of March 2024.

On January 24, 2024, Ørsted signed an agreement with Eversource to acquire Eversource’s 50 percent share of Sunrise Wind. The sale is subject to the successful selection of Sunrise Wind in the ongoing New York fourth solicitation for offshore wind capacity, signing of an OREC contract with NYSERDA, finalization of sale agreements, receipt of final federal construction permits, and relevant regulatory approvals. If Sunrise Wind is not successful in the solicitation, then the existing OREC contract for Sunrise Wind will be cancelled according to the state’s requirements, and Eversource and Ørsted’s joint venture for Sunrise Wind will remain in place. In that scenario, Ørsted and Eversource would then assess their options in determining the best path forward for Sunrise Wind and its assets, which include the BOEM offshore lease area. If Sunrise Wind’s revised bid is successful in the new solicitation, Sunrise Wind would have 90 days to negotiate a new OREC agreement at the re-bid price. In a successful re-bid, Ørsted would become the sole owner of Sunrise Wind, while Eversource would remain contracted to lead the project’s onshore construction. If Sunrise Wind is successful in the re-bid, Ørsted would pay Eversource 50 percent of the negotiated purchase price upon closing the sale transaction, with the remaining 50 percent paid when onshore construction is completed and certain other milestones are achieved. On January 25, 2024, Eversource and Ørsted submitted a new proposal for Sunrise Wind in the New York fourth offshore wind solicitation.

On February 13, 2024, Eversource announced that it has executed an agreement to sell its existing 50 percent interests in the South Fork Wind and Revolution Wind projects to Global Infrastructure Partners (GIP). As part of this transaction, Eversource expects to receive approximately $1.1 billion of cash proceeds upon closing, which includes the sales value related to the 10 percent energy community ITC adder of approximately $170 million related to Revolution Wind, and to exit these projects while retaining certain cost sharing obligations for the construction of Revolution Wind. The purchase price is subject to future post-closing adjustment payments based on, among other things, the progress, timing and expense of construction at each project. The cost sharing obligations provide that Eversource would share equally with GIP in GIP’s funding obligations for up to approximately $240 million of incremental capital expenditure overruns incurred during the construction phase for the Revolution Wind project, after which GIP’s obligations for any additional capital expenditure overruns would be shared equally by Eversource and Ørsted. Additionally, Eversource’s financial exposure will be adjusted by certain purchase price adjustments to be made following commercial operation of the Revolution Wind project and closing of South Fork as a result of final project economics, which includes Eversource’s obligation to maintain GIP’s internal rate of return for each project as specified in the agreement. Eversource currently expects that South Fork Wind will reach full commercial operation prior to closing of the sale with GIP and Eversource does not expect any material cost sharing or other purchase price adjustment payments for South Fork Wind.

Factors that could result in Eversource’s total net proceeds from the transaction to be lower or higher include Revolution Wind’s eligibility for federal investment tax credits at other than the anticipated 40 percent level; the ultimate cost of construction and extent of cost overruns for Revolution Wind; delays in constructing Revolution Wind, which would impact the economics associated with the purchase price adjustment; and a benefit due to Eversource if there are lower operation costs or higher availability of the projects through the period that is four years following the commercial operation date of the Revolution Wind project.

Closing a transaction with GIP would be subject to customary conditions, including certain regulatory approvals under the Hart Scott Rodino Act and by the New York Public Service Commission and the FERC, as well as other conditions, among which is the completion and execution of the partnership agreements between GIP and Ørsted that will govern GIP’s new ownership interest in those projects following Eversource’s divestiture. Closing of the transaction is currently expected to occur in mid-2024. If closing of the sale is delayed, additional capital contributions made by Eversource would be recovered in the sales price. Under the agreement, Eversource’s existing credit support obligations are expected to roll off for each project around the time that each project completes its expected capital spend.

Impairment:Equity method investments are assessed for impairment when conditions exist as of the balance sheet date that indicate that the fair value of the investment ismay be less than book value. Eversource continually monitors and evaluates its equity method investments to determine if there are indicators of an other-than-temporary impairment. If the decline in value is considered to be other-than-temporary, the investment is written down to its estimated fair value, which establishes a new cost basis in the investment. Subsequent declines or recoveries after the reporting date are not considered in the impairment recognized. Investments that are other-than-temporarily impaired and written down to their estimated fair value cannot subsequently be written back up for increases in estimated fair value. Impairment evaluations involve a significant degree of judgment and estimation, including identifying circumstances that indicate an impairment may exist at the equity method investment level, selecting discount rates used to determine fair values, and developing undiscountedan estimate of discounted future cash flows.flows expected from investment operations or the sale of the investment.

During

In connection with the process to divest its offshore wind business, Eversource identified indicators for impairment in both the second and fourth quarters of 2023. In each impairment assessment, Eversource evaluated its investments and determined that the carrying value of the equity method offshore wind investments exceeded the fair value of the investments and that the decline in fair value was other-than-temporary. The completion of the strategic review in the second quarter of 2023 resulted in Eversource recording a pre-tax other-than-temporary impairment charge of $401 million ($331 million after-tax) to reflect the investment at estimated fair value based on the expected sales price at that time. This established a new cost basis in the investments. Negative developments in the fourth quarter of 2023, including a lower expected sales price, additional projected construction cost increases, and the October 2023 OREC pricing denial for Sunrise Wind, resulted in Eversource conducting an impairment evaluation and recognizing an additional pre-tax other-than-temporary impairment charge of $1.77 billion ($1.62 billion after-tax) and establishing a new cost basis in the investments as of December 31, 2023. The Eversource statement of income reflects a total pre-tax other-than-temporary impairment charge of $2.17 billion ($1.95 billion after-tax) in its offshore wind investments for the year ended 2023.

The impairment evaluations involved judgments in developing the estimates and timing of the future cash flows arising from the expected sales price of Eversource’s 50 percent interest in the wind projects, including expected sales value from investment tax credit adder amounts, less estimated costs to sell, and uncertainties related to the Sunrise Wind re-bid process in New York’s offshore wind solicitation. Additional assumptions in the fourth quarter assessment included revised projected construction costs and estimated project cost overruns, estimated termination costs, salvage values of Sunrise Wind assets, and the value of the tax equity ownership interest. The assumptions used in the discounted cash flow analyses are subject to inherent uncertainties and subjectivity. The use of different assumptions, estimates, or judgments with respect to the estimation of future cash flows could materially change the impairment charges. The impairment evaluations were based on best information available at the impairment assessment dates. New information from events or circumstances arising after the balance sheet date, such as the January 25, 2024 re-bid of Sunrise Wind in the New York solicitation, are not included in the December 31, 2023 impairment evaluation. All significant inputs into the impairment evaluations were Level 3 fair value measurements.

The expected cash flows arising from the anticipated sales are a significant input in the impairment evaluation. In the fourth quarter of 2023, project construction forecasts were updated, and these new forecasts reflected additional expenditures for construction and scheduling related pressures, including the availability and increased cost of installation vessels and supply chain cost increases related to foundation fabrication. In determining the current fair value of the investments, these updated projections exceeded the previously estimated projections for construction expenditures, which resulted in a revised sales price that was significantly lower than the previous bid value. Another significant assumption in the impairment evaluation includes the probability of payment of future cost overruns on the three wind projects through each project's respective commercial operation date, which would not be recovered in the expected sales price. This assumption was based on construction projections updated in the fourth quarter of 2023 exceeding prior estimates. An increase in expected cost overruns could result in a significant impairment in a future period.

Another key assumption in the impairment model of our offshore wind investments was investment tax credit (“ITC”) adders that were included in the Inflation Reduction Act and were a separate part of the sales price value offered by GIP. An ITC adder is an additional 10 percent of credit value for ITC eligible costs and include two distinct qualifications related to either using domestic sourced materials (domestic content) or construction of an onshore substation in a designated community (energy community). Similar to the base ITC of 30 percent of the eligible costs, any ITC adders generated would be used to reduce an owner’s federal tax liability and could be used to receive tax refunds from prior years as well. Management believes there is a high likelihood that the 10 percent energy community ITC adder is realizable, and that ITC adder would amount to approximately $170 million of additional sales value related to Revolution Wind and that it would qualify for the ITC adder after it reaches commercial operation in 2025. Although management believes the ITC adder value is realizable, there is some uncertainty at this time as to whether or not those ITC adders can be achieved, and management continues to evaluate the project’s qualifications and to monitor guidance issued by the United States Treasury Department. A change in the expected value or qualification of ITC adders could result in a significant impairment in a future period.

Another fourth quarter 2023 development included in the impairment evaluation is the key judgment regarding the probability of future cash inflows and outflows associated with the sale or abandonment of the Sunrise Wind project and the expected outcome of the New York fourth offshore wind solicitation in 2024. In June 2023, Sunrise Wind filed a petition with the New York State Public Service Commission for an order authorizing NYSERDA to amend the Sunrise Wind OREC contract to increase the contract price to cover increased costs and inflation. At that time, management expected the contract repricing would be successful given NYSERDA’s public support for pricing adjustments. On October 12, 2023, the New York State Public Service Commission denied this petition. Subsequent to the denial, on November 30, 2023, the general terms of an expedited offshore wind renewable energy solicitation in New York were released. A primary condition for Sunrise Wind to participate in this new solicitation was to agree to terminate its existing OREC agreement. As of December 31, 2023, Eversource and Ørsted were considering whether to submit a new bid for Sunrise Wind, the price at which a new bid would be made, and the probability of success in the new bidding process. The December 31, 2023 impairment evaluation included management’s judgment of the likelihood of possible future scenarios that included the Sunrise Wind project continuing with its existing OREC contract, the project re-bidding and being selected in the new solicitation, the project re-bidding and not being selected, or the project not moving forward. The unfavorable development of the October 2023 denial of the OREC pricing petition, management’s assessment of the likelihood of success in the competitive New York re-bidding process, and the increased costs to build the project, have resulted in management’s assumption that the Sunrise Wind project will ultimately be abandoned, and therefore, no sales value was modeled in the impairment evaluation. Additionally, in the abandonment assumption, management has assumed the loss of contingent sales value associated with any related ITC adders and has estimated future cash outflows for Eversource’s share of cancellation costs required under Sunrise Wind’s supplier contracts, partially offset by expected salvage value and expected cost overruns not incurred in the case of abandonment that are included in the fourth quarter 2023 impairment charge. An increase in expected cancellation costs could result in a significant impairment in a future period.

Management will continue to monitor and evaluate all facts and circumstances in the offshore wind sales process and the impact on its investment balance. Adverse changes in facts and circumstances of estimates and timing of future cash flows and the factors described above could result in the recognition of additional, significant impairment charges that could be material to the financial statements.

The impairment charge was a non-cash charge and did not impact Eversource’s cash position. Eversource will continue to make future cash expenditures for required cash contributions to its offshore wind investments up to the time of disposition of each of the offshore wind projects. Capital contributions are expected until the sales are completed and changes in the timing and amounts of these contributions would be adjusted in the sales prices and therefore not result in an additional impairment charge. Proceeds from the transactions will be used to pay off parent company debt. Eversource’s offshore wind investments do not meet the criteria to qualify for presentation as a discontinued operation.

Capital contributions in the offshore wind investments, including the 2023 contribution for the tax equity investment in South Fork Wind, are included in Investments in Unconsolidated Affiliates on the statements of cash flows. Proceeds received from the 2023 sale of the uncommitted lease area and from an October 2023 distribution of $318 million received primarily as a result of being a 50 percent joint owner in the Class B shares of South Fork Wind which was restructured as a tax equity investment, are included in Proceeds from Unconsolidated Affiliates on the statement of cash flows.

As of December 31, 2023, Eversource’s share of underlying equity in net assets of the offshore wind business exceeded the carrying amount of the offshore wind investments as a result of the 2023 impairments. As of December 31, 2022, the carrying amount of Eversource’s offshore wind investments exceeded its share of underlying equity in net assets by $343.1 million. The basis differences as of December 31, 2022 were primarily comprised of $168.9 million of equity method goodwill that was not being amortized, intangible assets for PPAs, and capitalized interest.

Liquidation of Renewable Energy Investment Fund: On March 21, 2023, Eversource’s equity method investment in a renewable energy investment fund was liquidated by the fund’s general partner in accordance with the partnership agreement. Proceeds received from the liquidation totaled $147.6 million and are included in Proceeds from Unconsolidated Affiliates on the statement of cash flows for the year ended December 31, 2020,2023. A portion of the proceeds was used to make a charitable contribution to the Eversource recorded an other-than-temporary impairmentEnergy Foundation (a related party) of $2.8$20.0 million withinin 2023. The liquidation benefit received in excess of the investment’s carrying value and the charitable contribution are included in Other Income, Net on the statement of income, related to a write-off of an investment within a renewable energy fund.income.

During the year endedNSTAR Electric: As of December 31, 2018, Eversource recorded an other-than-temporary impairment2023 and 2022, NSTAR Electric's investments included a 14.5 percent ownership interest in two companies that transmit hydro-electricity imported from the Hydro-Quebec system in Canada of $32.9$9.6 million within Other Income, Net on the statement of income, related to Access Northeast, a natural gas pipeline and storage project, which represented the full carrying value of our equity method investment. On April 1, 2019, pursuant to a provision in the partnership agreement jointly entered into by Eversource, Enbridge, Inc. and National Grid plc, through Algonquin Gas Transmission, LLC, the Access Northeast project was terminated.$9.3 million, respectively.

7.     ASSET RETIREMENT OBLIGATIONS

Eversource, including CL&P, NSTAR Electric and PSNH, recognizes a liability for the fair value of an ARO on the obligation date if the liability's fair value can be reasonably estimated, even if it is conditional on a future event.  Settlement dates and future costs are reasonably estimated when sufficient information becomes available.  Management has identified various categories of AROs, primarily CYAPC's and YAEC's obligation to dispose of spent nuclear fuel and high level waste, and also certain assets containing asbestos and hazardous contamination. Management has performed fair value calculations reflecting expected probabilities for settlement scenarios.

The fair value of an ARO is recorded as a long-term liability in Other Long-Term Liabilities with a corresponding amount included in Property, Plant and Equipment, Net on the balance sheets.  The ARO assets are depreciated, and the ARO liabilities are accreted over the estimated life of the obligation and the corresponding credits are recorded as accumulated depreciation and ARO liabilities, respectively.  As the electric and natural gas companies are rate-regulated on a cost-of-service basis, these companies apply regulatory accounting guidance and both the depreciation and accretion costs associated with these companies' AROs are recorded as increases to Regulatory Assets on the balance sheets.  

A reconciliation of the beginning and ending carrying amounts of ARO liabilities is as follows:

Eversource's amounts include CYAPC and YAEC's AROs of $330.3$315.8 million and $337.7$320.5 million as of December 31, 20202023 and 2019,2022, respectively. The fair value of the ARO for CYAPC and YAEC includes uncertainties of the fuel off-load dates related to the DOE's timing of performance regarding its obligation to dispose of the spent nuclear fuel and high level waste and other assumptions, including discount rates.  The incremental asset recorded as an offset to the ARO liability was fully depreciated since the plants have no remaining useful life.  Any changes in the ARO liability are recorded with a corresponding offset to the related regulatory asset.  The assets held in the CYAPC and YAEC spent nuclear fuel trusts are restricted for settling the ARO and all other nuclear fuel storage obligations.  For further information on the assets held in the spent nuclear fuel trusts, see Note 5, "Marketable Securities," to the financial statements.

8.     SHORT-TERM DEBT

Short-Term Debt - Borrowing Limits:  The amount of short-term borrowings that may be incurred by CL&P and NSTAR Electric is subject to periodic approval by the FERC.  Because the NHPUC has jurisdiction over PSNH's short-term debt, PSNH is not currently required to obtain FERC approval for its short-term borrowings.  On October 25, 2019,November 30, 2023, the FERC granted authorization that allows CL&P to issue total short-term borrowings in an aggregate principal amount not to exceed $600 million outstanding at any one time, through December 31, 2021.2025.  On December 18, 2019,2023, the FERC granted authorization that allows NSTAR Electric to issue total short-term borrowings in an aggregate principal amount not to exceed $655 million outstanding at any one time, through December 31, 2021.2025.

Long-Term Debt Provisions:  The utility plant of CL&P, PSNH, Yankee Gas, NSTAR Gas, EGMA and a portion of Aquarion is subject to the lien of each company's respective first mortgage bond indenture.  The Eversource parent, NSTAR Electric and a portion of Aquarion debt is unsecured. Additionally, the long-term debt agreements provide that Eversource and certain of its subsidiaries must comply with certain covenants as are customarily included in such agreements, including equity requirements for NSTAR Electric, NSTAR Gas and Aquarion.  Under the equity requirements, NSTAR Electric's and Aquarion's senior notes must maintain a certain consolidated indebtedness to capitalization ratio as of the end of any fiscal quarter and NSTAR Gas' outstanding long-term debt must not exceed equity.

CL&P's obligation to repay the Pollution Control Revenue Bonds (PCRBs) is secured by first mortgage bonds.  The first mortgage bonds contain similar terms and provisions as the applicable series of PCRBs.  If CL&P fails to meet its obligations under the first mortgage bonds, then the holder of the first mortgage bonds (the issuer of the PCRBs) would have rights under the first mortgage bonds.  CL&P's tax-exempt PCRBs will be subject to redemption at par on or after September 1, 2021.

Certain secured and unsecured long-term debt securities are callable at redemption price or are subject to make-whole provisions.

No long-term debt defaults have occurred as of December 31, 2020.2023.

CYAPC's Pre-1983 Spent Nuclear Fuel Obligation:  Under the Nuclear Waste Policy Act of 1982, the DOE is responsible for the selection and development of repositories for, and the disposal of, spent nuclear fuel and high-level radioactive waste. CYAPC is obligated to pay the DOE for the costs to dispose of spent nuclear fuel and high-level radioactive waste generated prior to April 7, 1983 (pre-1983 Spent Nuclear Fuel). CYAPC has partially paid this obligation and recorded an accrual for the fullits remaining liability thereof to the DOE. This liability accrues interest costs at the 3-month Treasury bill yield rate. For nuclear fuel used to generate electricity prior to April 7, 1983, payment may be made any time prior to the first delivery of spent fuel to the DOE. Fees for disposal of nuclear fuel burned on or after April 7, 1983 were billed to member companies and paid to the DOE.
107



As of December 31, 20202023 and 2019,2022, as a result of consolidating CYAPC, Eversource has consolidated $11.7$12.5 million and $11.6$11.9 million, respectively, in pre-1983 spent nuclear fuel obligations to the DOE. In December 2019, CYAPC paid $29 million to the DOE to partially settle this obligation. The obligation includes accumulated interest costs of $8.7$9.5 million and $8.6$8.8 million as of December 31, 20202023 and 2019,2022, respectively.  CYAPC maintains a trust to fund amounts due to the DOE for the disposal of pre-1983 spent nuclear fuel.  For further information, see Note 5, "Marketable Securities," to the financial statements. Fees for disposal of nuclear fuel burned on or after April 7, 1983 were billed to member companies and paid to the DOE.

10.    RATE REDUCTION BONDS AND VARIABLE INTEREST ENTITIES

Rate Reduction Bonds: OnIn May 8, 2018, PSNH Funding, a wholly-owned subsidiary of PSNH, issued $635.7 million of securitized RRBs in multiple tranches with a weighted average interest rate of 3.66 percent, and final maturity dates ranging from 2026 to 2035.  The RRBs are expected to be repaid by February 1, 2033. RRB payments consist of principal and interest and are paid semi-annually, beginning on February 1, 2019. The RRBs were issued pursuant to a finance order issued by the NHPUC onin January 30, 2018 to recover remaining costs resulting from the divestiture of PSNH’s generation assets.

The proceeds were used by PSNH Funding to purchase PSNH’s stranded cost asset-recovery property, including its vested property right to bill, collect and adjust a non-bypassable stranded cost recovery charge from PSNH’s retail customers. The collections are used to pay principal, interest and other costs in connection with the RRBs. The RRBs are secured by the stranded cost asset-recovery property. Cash collections from the stranded cost recovery charges and funds on deposit in trust accounts are the sole source of funds to satisfy the debt obligation. PSNH is not the owner of the RRBs, and PSNH Funding’s assets and revenues are not available to pay PSNH’s creditors. The RRBs are non-recourse senior secured obligations of PSNH Funding and are not insured or guaranteed by PSNH or Eversource Energy.

PSNH Funding was formed solely to issue RRBs to finance PSNH's unrecovered remaining costs associated with the divestiture of its generation assets. PSNH Funding is considered a VIE primarily because the equity capitalization is insufficient to support its operations. PSNH has the power to direct the significant activities of the VIE and is most closely associated with the VIE as compared to other interest holders. Therefore, PSNH is considered the primary beneficiary and consolidates PSNH Funding in its consolidated financial statements. The following tables summarize the impact of PSNH Funding on PSNH's balance sheets and income statements:

Variable Interest Entities - Other: The Company's variable interests outside of the consolidated group include contracts that are required by regulation and provide for regulatory recovery of contract costs and benefits through customer rates.  Eversource, CL&P and NSTAR Electric hold variable interests in VIEs through agreements with certain entities that own single renewable energy or peaking generation power plants, with other independent power producers and with transmission businesses.  Eversource, CL&P and NSTAR Electric do not control the activities that are economically significant to these VIEs or provide financial or other support to these VIEs.  Therefore, Eversource, CL&P and NSTAR Electric do not consolidate these VIEs.

11.     EMPLOYEE BENEFITS

A.     Pension Benefits and Postretirement Benefits Other Than Pension
Eversource provides defined benefit retirement plans (Pension Plans) that cover eligible employees and are subject to the provisions of ERISA, as amended by the Pension Protection Act of 2006. Eversource's policy is to annually fund the Pension Plans in an amount at least equal to an amount that will satisfy all federal funding requirements. In addition to the Pension Plans, Eversource maintains non-qualified defined benefit retirement plans (SERP Plans), which provide benefits in excess of Internal Revenue Code limitations to eligible participants consisting of current and retired employees.

Eversource also provides defined benefit postretirement plans (PBOP Plans) that provide life insurance and a health reimbursement arrangement created for the purpose of reimbursing retirees and dependents for health insurance premiums and certain medical expenses to eligible employees that meet certain age and service eligibility requirements. The benefits provided under the PBOP Plans are not vested, and the Company has the right to modify any benefit provision subject to applicable laws at that time. Eversource annually funds postretirement costs through tax deductible contributions to external trusts.

The Pension, SERP and PBOP Plans cover eligible employees, including, among others, employees of the regulated companies. Because the regulated companies recover retiree benefit costs from customers through rates, regulatory assets are recorded in lieu of recording an adjustment to Accumulated Other Comprehensive Income/(Loss) as an offset to the funded status of the Pension, SERP and PBOP Plans.  Regulatory accounting is also applied to the portions of the Eversource Service retiree benefit costs that support the regulated companies, as these costs are also recovered from customers.  Adjustments to the Pension, SERP and PBOP Plans' funded status for the unregulated companies are recorded on an after-tax basis to Accumulated Other Comprehensive Income/(Loss).  For further information, see Note 2, "Regulatory Accounting," and Note 16, "Accumulated Other Comprehensive Income/(Loss)," to the financial statements.  

Funded Status:  The Pension, SERP and PBOP Plans are accounted for under the multiple-employer approach, with each operating company's balance sheet reflecting its share of the funded status of the plans.  Although Eversource maintains marketable securities in a benefit trust, the SERP Plans do not contain any assets.  For further information, see Note 5, "Marketable Securities," to the financial statements.  The following tables provide information on the plan benefit obligations, fair values of plan assets, and funded status:

Actuarial (Loss)/Gain: For the year ended December 31, 2020,2023, the increase in the benefit obligationactuarial loss was primarily attributable to a decrease in the discount rate, which resulted in an increase to Eversource's pension liability of $603.0 million. The increase in thePension and SERP Plans’ projected benefit obligation was partially offset by the actual return on assets exceeding the expected asset return and changes in the mortality assumption.of $98.9 million. For the year ended December 31, 2019,2022, the increase in the benefit obligationactuarial gain was primarily attributable to a decreasean increase in the discount rate, which resulted in an increasea decrease to Eversource's pension liability of $813.1 million, which was partially offset by changes in actual plan experience and changes in other assumptions.

The pensionPension and SERP Plans' funded status includes the current portionPlans’ projected benefit obligation of the SERP liability totaling $6.8 million and $8.7 million as of December 31, 2020 and 2019, respectively, which is included in Other Current Liabilities on the balance sheets.

The Eversource PBOP funded status includes prepaid assets of $34.7 million and $62.7 million recorded in Other Long-Term Assets and liabilities of $24.5 million and $25.8 million included in Accrued Pension, SERP and PBOP on the balance sheets as of December 31, 2020 and 2019, respectively.

Actuarial Gain/(Loss): For the year ended December 31, 2020,2023, the increase in the benefit obligationactuarial gain was primarily attributable to changes to termination, retirement, and dependency rates that were updated as a result of an experience study performed in 2023, updated census data, changes to plan provisions, and other assumption changes, which resulted in a decrease to the Eversource PBOP projected benefit obligation of $17 million. The actuarial gain was partially offset by a decrease in the discount rate, which resulted in an increase to the Eversource PBOP liabilityprojected benefit obligation of $68.3 million, and by changes in our retirement assumptions.$12 million. For the year ended December 31, 2019,2022, the increase in the benefit obligationactuarial gain was primarily attributable to a decreasean increase in the discount rate, which resulted in an increasea decrease to the Eversource PBOP liabilityprojected benefit obligation of $88.6$180.1 million.

Expense:  Eversource charges net periodic benefit plan expense/(income) for the Pension, SERP and PBOP Plans to its subsidiaries based on the actual participant demographic data for each subsidiary's participants.  The actual investment return in the trust is allocated to each of the subsidiaries annually in proportion to the investment return expected to be earned during the year. The Company utilizes the spot rate methodology to estimate the discount rate for the service and interest cost components of benefit expense, which provides a morerelatively precise measurement by matching projected cash flows to the corresponding spot rates on the yield curve.

The components of net periodic benefit plan expense/(income) for the Pension, SERP and PBOP Plans, prior to amounts capitalized as Property, Plant and Equipment or deferred as regulatory assetsassets/(liabilities) for future recovery or refund, are shown below. The service cost component of net periodic benefit plan expense/(income), less the capitalized portion, is included in Operations and Maintenance expense on the statements of income. The remaining components of net periodic benefit plan expense/(income), less the deferred portion, are included in Other Income, Net on the statements of income. Pension, SERP and PBOP expense reflected in the statements of cash flows for CL&P, NSTAR Electric and PSNH does not include the intercompany allocations or the corresponding capitalized and deferred portion,of net periodic benefit plan expense/(income), as these amounts are cash settled on a short-term basis.

Eversource Contributions:   Based on the current status of the Pension Plans and federal pension funding requirements, there is no minimum funding requirement for our Eversource currently expectsService Pension Plan in 2024 and we do not expect to make pension contributions of $130.0in 2024. We do not expect to make any contributions to the Eversource Service PBOP Plan in 2024.

Eversource contributed $5.0 million and $1.9 million to the Aquarion Pension and PBOP Plans, respectively, in 2021, of which $78.9 million will be contributed by CL&P.  The remaining $51.1 million is expected to be contributed by other Eversource subsidiaries, primarily Eversource Service.2023. Eversource currently estimates contributing $2.8$5.0 million and $2.4 million to the Aquarion Pension and PBOP Plans, respectively, in 2021.2024.  

Fair Value of Pension and PBOP Plan Assets:  Pension and PBOP funds are held in external trusts.  Trust assets, including accumulated earnings, must be used exclusively for Pension and PBOP payments.  Eversource's investment strategy for its Pension and PBOP Plans is to maximize the long-term rates of return on these plans' assets within an acceptable level of risk.  The investment strategyguidelines for each asset category includes a diversification of asset types, fund strategies and fund managers and it establishes target asset allocations that are routinely reviewed and periodically rebalanced.  PBOP assets are comprised of assets held in the PBOP Plan trust, as well as specific assets within the Pension Plan trust (401(h) assets).  The investment policy and strategy of the 401(h) assets is consistent with that of the defined benefit pension plan. Eversource's expected long-term rates of return on Pension and PBOP Plan assets are based on target asset allocation assumptions and related expected long-term rates of return.  In developing its expected long-term rate of return assumptions for the Pension and PBOP Plans, Eversource evaluated input from consultants, as well as long-term inflation assumptions and historical returns. Management has assumed long-term rates of return of 8.25 percent for the Eversource Service Pension Plan assets, the Eversource Service PBOP Plan assets and PBOPthe Aquarion Pension Plan assets, and a 7 percent long-term rate of return for the Aquarion PlansPBOP Plan, to estimate its 20212024 Pension and PBOP costs.

C.    Share-Based Payments
Share-based compensation awards are recorded using a fair-value based method at the date of grant.  Eversource, CL&P, NSTAR Electric and PSNH record compensation expense related to these awards, as applicable, for shares issued or sold to their respective employees and officers, as well as for the allocation of costs associated with shares issued or sold to Eversource's service company employees and officers that support CL&P, NSTAR Electric and PSNH.  

Eversource Incentive Plans:  Eversource maintains long-term equity-based incentive plans in which Eversource, CL&P, NSTAR Electric and PSNH employees, officers and board members are eligible to participate.  The incentive plans authorize Eversource to grant up to 6,700,000 7,400,000new shares for various types of awards, including RSUs and performance shares, to eligible employees, officers, and board members. As of December 31, 20202023 and 2019,2022, Eversource had 2,876,6014,587,376 and 3,302,526903,183 common shares, respectively, available for issuance under these plans.

Eversource accounts for its various share-based plans as follows:

RSUs - Eversource records compensation expense, net of estimated forfeitures, on a straight-line basis over the requisite service period based upon the fair value of Eversource's common shares at the date of grant.  The par value of RSUs is reclassified to Common Stock from Capital Surplus, Paid In as RSUs become issued as common shares.

Performance Shares - Eversource records compensation expense, net of estimated forfeitures, on a straight-line basis over the requisite service period. Performance shares vest based upon the extent to which Company goals are achieved.  Vesting of outstanding performance shares is based upon both the Company's EPS growth over the requisite service period and level of payout is determined based on the total shareholder return as compared to the Edison Electric Institute (EEI) Index during the requisite service period.  The fair value of performance shares is determined at the date of grant using a lattice model. Compensation expense is subject to volatility until payout is established.

RSUs:  Eversource granted RSUs under the annual long-term incentive programs that are subject to three-year graded vesting schedules for employees, and one-year graded vesting schedules, or immediate vesting, for board members.  RSUs are paid in shares, reduced by amounts sufficient to satisfy withholdings for income taxes, subsequent to vesting.  A summary of RSU transactions is as follows:

20202022 Federal Legislation: On March 27, 2020, President TrumpAugust 16, 2022, the Inflation Reduction Act of 2022 (IRA) was signed into law. This is a broad package of legislation that includes incentives and support for clean energy resource development. Most notable for Eversource, the $2.2 trillion bipartisan Coronavirus Aid, Relief,investment tax credit (ITC) on offshore wind projects increases from 30 percent to 40 percent if certain requirements for labor and Economic Security (CARES) Act. Among otherdomestic content are met. The act also re-establishes the production tax credit for solar and wind energy projects, gives increased credit for projects in certain communities, and sets credits for qualifying clean energy generation and energy storage projects. The tax provisions of the CARES Act providesIRA provide additional incentives for loansoffshore wind projects and other benefits to small and large businesses, expanded unemployment insurance, direct paymentscould reduce retail electricity costs for our customers related to those clean energy investments. The IRA includes other tax provisions focused on implementing a 15 percent minimum tax on adjusted financial statement income and a one percent excise tax on corporate share repurchases. The Department of Treasury and the Internal Revenue Service issued some guidance during 2023; however, they are expected to issue additional needed guidance with wages middle-income and below, new appropriations funding for health care and other priorities, and tax changes like deferrals of employer payroll tax liabilities coupled with an employee retention tax credit and rollbacks of Tax Cuts and Jobs Act of 2017 limitations on net operating losses and certain business interest limitation. For the year ended December 31, 2020, we have recorded a tax liability of approximately $39 million relatedrespect to the deferral of employer payroll tax liability provision. Fifty percentapplication of the deferral of employer payrollnewly enacted IRA provisions in the future. We will continue to monitor and evaluate impacts on our consolidated financial statements. We currently do not expect the alternative minimum tax liability must be paid by December 31, 2021 and the remaining amount by December 31, 2022. Other than the cash flow benefit described, the CARES Act did notchange to have a material impact.

On December 27, 2020, President Trump signed into law H.R. 133, the “Consolidated Appropriations Act, 2021.” The House of Representatives and Senate previously passed the bill with overwhelming support. The legislation includes tax extenders as part of Division EE, the “Taxpayer Certainty and Disaster Tax Relief Act of 2020.” The provisions within the law include the extension of the Investment Tax Credit (ITC) for solar at 26 percent for facilities the construction of which begins through the end of 2022, at 22 percent for facilities the construction of which begins in 2023, and postponement of the date after which solar facilities placed in service receive only a 10 percent ITC to December 31, 2025, the extension of the ITC at 30 percent (with no phase-down) to offshore wind if construction begins by December 31, 2025 (qualifying offshore wind includes facilities located in the inland navigable watersimpact on our earnings, financial condition or in the coastal waters of the U.S.), and the extension and expansion of the CARES Act employee retention tax credit for the period from January 1, 2021 through June 30, 2021, including increasing the credit rate from 50 percent to 70 percent of qualified wages, and increasing the per-employee creditable wages limit from $10,000 per year to $10,000 for each quarter. The tax credit provision impacts to Eversource are still being evaluated but are a significant positive development for the Company and provides the opportunity to generate additional tax credits in its renewable energy projects when the projects become operational.cash flows.

13.     COMMITMENTS AND CONTINGENCIES

A.     Environmental Matters
Eversource, CL&P, NSTAR Electric and PSNH are subject to environmental laws and regulations intended to mitigate or remove the effect of past operations and improve or maintain the quality of the environment.  These laws and regulations require the removal or the remedy of the effect on the environment of the disposal or release of certain specified hazardous substances at current and former operating sites. Eversource, CL&P, NSTAR Electric and PSNH have an active environmental auditing and training program and each believes it is substantially in compliance with all enacted laws and regulations.

Environmental reserves are accrued when assessments indicate it is probable that a liability has been incurred and an amount can be reasonably estimated.  The approach used estimates the liability based on the most likely action plan from a variety of available remediation options, including no action required or several different remedies ranging from establishing institutional controls to full site remediation and monitoring.  These liabilities are estimated on an undiscounted basis and do not assume that the amounts are recoverable from insurance companies or other third parties.  The environmental reserves include sites at different stages of discovery and remediation and do not include any unasserted claims.

These reserve estimates are subjective in nature as they take into consideration several different remediation options at each specific site.  The reliability and precision of these estimates can be affected by several factors, including new information concerning either the level of contamination at the site, the extent of Eversource's, CL&P's, NSTAR Electric's and PSNH's responsibility for remediation or the extent of remediation required, recently enacted laws and regulations or changes in cost estimates due to certain economic factors. It is possible that new information or future developments could require a reassessment of the potential exposure to required environmental remediation.  As this information becomes available, management will continue to assess the potential exposure and adjust the reserves accordingly.  

The amounts recorded as environmental reserves are included in Other Current Liabilities and Other Long-Term Liabilities on the balance sheets and represent management's best estimate of the liability for environmental costs, and take into consideration site assessment, remediation and long-term monitoring costs.  The environmental reserves also take into account recurring costs of managing hazardous substances and pollutants, mandated expenditures to remediate contaminated sites and any other infrequent and non-recurring clean-up costs.  A reconciliation of the activity in the environmental reserves is as follows:

20195715159
EversourceCL&PNSTAR ElectricPSNH

The increase in the reserve balance was due primarily to the addition of 9 MGPone environmental site at NSTAR Gas, two additional sites at the EGMA natural gas business resulting from the CMA acquisitionNSTAR Electric, three additional sites at CL&P, and changes in cost estimates at thecertain MGP sites at our natural gas companies MGP sites and at CL&PPSNH for which additional remediation will be required.

Included in the number of sites and reserve amounts above are former MGP sites that were operated several decades ago and manufactured natural gas from coal and other processes, which resulted in certain by-products remaining in the environment that may pose a potential risk to human health and the environment, for which Eversource may have potential liability.  The reserve balances related to these former MGP sites were $92.2$117.1 million and $67.9$112.6 million as of December 31, 20202023 and 2019,2022, respectively, and related primarily to the natural gas business segment.

As of December 31, 2020, for 6 environmental sites (1 for CL&P) that are included in the Company's reserve for environmental costs, the information known and the nature of the remediation options allow for the Company to estimate the range of losses for environmental costs.  As of December 31, 2020, $41.7 million (including $0.9 million for CL&P) had been accrued as a liability for these sites, which represents the low end of the range of the liabilities for environmental costs.  Management believes that additional losses of up to approximately $33 million ($0.5 million at CL&P) may be incurred in executing current remediation plans for these sites.  
125


As of December 31, 2020,2023, for 1519 environmental sites (7(11 for CL&P and 21 for NSTAR Electric) that are included in the Company's reserve for environmental costs, management cannot reasonably estimate the exposure to loss in excess of the reserve, or range of loss, as these sites are under investigation and/or there is significant uncertainty as to what remedial actions, if any, the Company may be required to undertake.  As of December 31, 2020, $17.52023, $39.9 million (including $2.6$12.6 million for CL&P and $0.4$0.3 million for NSTAR Electric) had been accrued as a liability for these sites.

As of December 31, 2020,2023, for 7 environmental sites (1 for CL&P) that are included in the Company's reserve for environmental costs, the information known and the nature of the remediation options allow for the Company to estimate the range of losses for environmental costs.  As of December 31, 2023, $29.4 million (including $0.4 million for CL&P) has been accrued as a liability for these sites, which represents the low end of the range of the liabilities for environmental costs.  Management believes that additional losses of up to approximately $17.7 million ($0.5 million at CL&P) may be incurred in executing current remediation plans for these sites.
As of December 31, 2023, for the remaining 4239 environmental sites (including 74 for CL&P, 1011 for NSTAR Electric and 98 for PSNH) that are included in the Company's reserve for environmental costs, the $43.2$58.9 million accrual (including $8.8$0.8 million for CL&P, $4.3$5.1 million for NSTAR Electric and $7.1$7.6 million for PSNH) represents management's best estimate of the probable liability and no additional loss is anticipatedestimable at this time.

PSNH, NSTAR Gas, EGMA and Yankee Gas have rate recovery mechanisms for MGP related environmental costs, therefore, changes in their respective environmental reserves do not impact Net Income. CL&P is allowed to defer certain environmental costs for future recovery.  NSTAR Electric does not have a separate environmental cost recovery regulatory mechanism.

Renewable Energy and Purchase Contracts includes long-term commitments of NSTAR Electric pertaining to the Vineyard Wind LLC contract awarded under the Massachusetts Clean Energy 83C procurement solicitation. NSTAR Electric, along with other Massachusetts distribution companies, entered into 20-year contracts to purchase electricity generated by this 800 megawatt offshore wind project. Construction on the Vineyard Wind project commenced in 2022. Estimated energy costs under this contract are expected to begin when the facilities are in service in 2024 and range between $100 million and $200 million per year under NSTAR Electric’s 20-year contract, totaling approximately $2.6 billion.

As required by 2018 regulation, CL&P and UI each entered into PURA-approved ten-year contracts in 2019 to purchase a combined total of approximately 9 million MWh annually from the Millstone Nuclear Power Station generation facility. On March 15, 2019, CL&P and UI each signed a ten-year contract with the owner of Millstone Nuclear Power Station in order to purchasefacility, which represents a combined amount of approximately 50 percent of the facility's output (approximately 40 percent by CL&P). The Millstone Nuclear Power Station has a 2,112 MW nameplate capacity. PURA approved the contracts on September 18, 2019. Energy deliveries and payments under these contracts began in the fourth quarter of 2019.

CL&P and UI were alsoAlso as required by 2018 regulation, to enterCL&P and UI each entered into PURA-approved eight-year contracts in 2019 to purchase a combined amount of approximately 18 percent of the facility'sSeabrook Nuclear Power Plant’s output (approximately 15 percent by CL&P) from the Seabrook Nuclear Power Plant beginning January 1, 2022. The Seabrook Nuclear Power Plant has an approximate 1,250 MW nameplate capacity. On November 22, 2019, CL&P and UI each signed an eight-year contract with the owner of the Seabrook Nuclear Power Plant. PURA approved the contracts on November 27, 2019.

The total estimated remaining future cost of the Millstone Nuclear Power Station and Seabrook Nuclear Power Plant energy purchase contracts are $3.6$2.4 billion and are reflected in the table above. CL&P sells the energy purchased under these contracts into the market and uses the proceeds from these energy sales to offset the contract costs.  As the net costs under these contracts are recovered from customers in future rates, the contracts do not have an impact on the net income of CL&P. These contracts do not meet the definition of a derivative, and accordingly, the costs of these contracts are being accounted for as incurred.

Excluded from the table above are long-term commitments of NSTAR Electric pertaining to the Massachusetts Clean Energy 83D contract, for which construction had not commenced by December 31, 2020. Estimated costs under this contract are expected to begin in 2023 and range between $150 million and $415 million per year under a 20-year contract, totaling approximately $6.7 billion.

The contractual obligations table above does not include long-term commitments signed by CL&P and NSTAR Electric, as required by the PURA and the DPU, respectively, for the purchase of renewable energy and related products that are contingent on the future construction of energy facilities.facilities, such as the long-term commitments of NSTAR Electric pertaining to the Massachusetts Clean Energy 83D contract entered into in 2018.

Natural Gas Procurement:  Eversource's natural gas distribution businesses have long-term contracts for the purchase, transportation and storage of natural gas as part of its portfolio of supplies, which extend through 2045. Long-term purchases for natural gas procurement include contracts of EGMA, which was formed as a result of the CMA asset acquisition.

Purchased Power and Capacity:  These contracts include capacity CfDs ofwith generation facilities at CL&P through 2026, and various IPP contracts or purchase obligations for electricity which extend through 2024 for CL&P and 2031 for NSTAR Electric and 2023 for PSNH.

CL&P, along with UI, has 3 capacity CfDs consisting of 2 generation units and 1 demand response project.  The combined capacities of these contracts as of December 31, 2020 and 2019 were 675 MW and 676 MW, respectively. The capacity CfDs extend through 2026 and obligate both CL&P and UI to make or receive payments on a monthly basis to or from the generation facilities based on the difference between a set contractual capacity price and the capacity market prices received by the generation facilities in the ISO-NE capacity markets.  CL&P has a sharing agreement with UI, whereby UI shares 20 percent of the costs and benefits of these contracts.Electric. CL&P's portion of the costs and benefits ofunder these capacity contracts will be paid by,are recovered from, or refunded to, CL&P's customers.

The contractual obligations table above does not include CL&P's, NSTAR Electric's or PSNH's standard/basic service contracts for the purchase of energy supply, the amounts of which vary with customers' energy needs.

Peaker CfDs:  CL&P, along with UI, has 3three peaker CfDs for a total of approximately 500 MW of peaking capacity through 2042.  CL&P has a sharing agreement with UI, whereby CL&P is responsible for 80 percent and UI for 20 percent of the net costs or benefits of these CfDs.  The Peaker CfDs pay the generation facility owner the difference between capacity, forward reserve and energy market revenues and a cost-of-service payment stream for 30 years.  The ultimate cost or benefit to CL&P under these contracts will depend on the costs of plant operation and the prices that the projects receive for capacity and other products in the ISO-NE markets.  CL&P's portion of the amounts paid or received under the Peaker CfDs are recovered from, or refunded to, CL&P's customers.

Transmission Support Commitments:  Along with other New England utilities, CL&P, NSTAR Electric and PSNH have entered into a series of agreements in the 1980’s to support the costs of, and receive rights to use, transmission and terminal facilities that were built to import electricity from the Hydro-Québec system in Canada. CL&P, NSTAR Electric and PSNH wereare obligated to pay, over a 30-year20-year period ending in 2020,2040, their proportionate shares of the annual operation and maintenance expenses and capital costs of those facilities. On December 18, 2020, the parties to these agreements submitted to FERC an offer of settlement and amendments to these agreements implementing the terms of an extension for an additional 20-year period. The parties have requested these terms to be placed in effect as of January 1, 2021 or such other date as authorized by FERC. The estimated future annual costs included in the contractual obligations table above, are subject to the approval of these amendments by FERC and can vary as a result.

C.     Spent Nuclear Fuel Obligations - Yankee Companies
CL&P, NSTAR Electric and PSNH have plant closure and fuel storage cost obligations to the Yankee Companies, which have each completed the physical decommissioning of their respective nuclear power facilities and are now engaged in the long-term storage of their spent fuel. The Yankee Companies fund these costs through litigation proceeds received from the DOE and, to the extent necessary, through wholesale, FERC-approved rates charged under power purchase agreements with several New England utilities, including CL&P, NSTAR Electric and PSNH. CL&P, NSTAR Electric and PSNH, in turn recover these costs from their customers through state regulatory commission-approved retail rates. The Yankee Companies collect amounts that management believes are adequate to recover the remaining plant closure and fuel storage cost

estimates for the respective plants. Management believes CL&P and NSTAR Electric will recover their shares of these obligations from their customers. PSNH has recovered its total share of these costs from its customers.

Spent Nuclear Fuel Litigation:
The Yankee Companies have filed complaints against the DOE in the Court of Federal Claims seeking monetary damages resulting from the DOE's failure to accept delivery of, and provide for a permanent facility to store, spent nuclear fuel pursuant to the terms of the 1983 spent fuel and high-level waste disposal contracts between the Yankee Companies and the DOE. The court previously awarded the Yankee Companies damages for Phases I, II, III and IIIIV of litigation resulting from the DOE's failure to meet its contractual obligations. These Phases covered damages incurred in the years 1998 through 2012,2016, and the awarded damages have been received by the Yankee Companies with certain amounts of the damages refunded to their customers.

DOE Phase IVV Damages - On May 22, 2017,March 25, 2021, each of the Yankee Companies filed a fourthfifth set of lawsuits against the DOE in the Court of Federal Claims. The Yankee Companies sought monetary damages totaling $104.4 million for CYAPC, YAEC and MYAPC,Claims resulting from the DOE's failure to begin accepting spent nuclear fuel for disposal covering the years from 20132017 to 2016 (DOE Phase IV). On February 21, 2019,2020. The Yankee Companies filed claims seeking monetary damages totaling $120.4 million for CYAPC, YAEC and MYAPC. Pursuant to a June 2, 2022 court order, the Yankee Companies received a partial summary judgment and partial final judgment in their favor for the undisputed amount ofwere subsequently permitted to include monetary damages of $103.2 million.  The court awarded CYAPC, YAEC and MYAPC damages of $40.7 million, $28.1 million and $34.4 million, respectively. The DOE did not appealrelating to the court's judgment and the decision became final on April 23, 2019. On June 12, 2019, each of the Yankee Companies received the damages proceeds. On June 12, 2019, the court accepted an offer of judgmentyear 2021 in the amount of $0.5 million to settle the disputed amount of approximately $1 million inDOE Phase IV contested damages.V complaint. The Yankee Companies receivedsubmitted a supplemental filing to include these costs of $33.1 million on June 8, 2022. The DOE Phase V trial is expected to begin in the $0.5 million payment in July 2019.spring of 2024.

In September 2019, the Yankee Companies made a required informational filing with FERC as to the use of proceeds, for which approval was received in the fourth quarter of 2019. In December 2019, YAEC and MYAPC returned proceeds of $5.4 million and $21.0 million, respectively, to its member companies, of which the Eversource utilities (CL&P, NSTAR Electric and PSNH) received a total of $2.8 million from YAEC and $5.0 million from MYAPC. The Eversource utilities refund these amounts received to their utility customers. Also, in December 2019, CYAPC paid $29.0 million to the DOE to partially settle its pre-1983 spent nuclear fuel obligation.

D.    Guarantees and Indemnifications
In the normal course of business, Eversource parent provides credit assurances on behalf of its subsidiaries, including CL&P, NSTAR Electric and PSNH, in the form of guarantees. Management does not anticipate a material impact to net income or cash flows as a result of these various guarantees and indemnifications. 

Guarantees issued on behalf of unconsolidated entities, including equity method offshore wind investments, for which Eversource parent is the guarantor, are recorded at fair value as a liability on the balance sheet at the inception of the guarantee. The fair value of guarantees issued on behalf of unconsolidated entities are recorded within Other Long-Term Liabilities on the balance sheet, and were $4.4 million and $4.2 million as of December 31, 2023 and 2022, respectively. Eversource regularly reviews performance risk under these guarantee arrangements, and inbelieves the likelihood of payments being required under the guarantees is remote. In the event it becomes probable that Eversource parent will be required to perform under the guarantee, the amount of probable payment will be recorded. The fair value of guarantees issued on behalf of unconsolidated entities are recorded within Other Long-Term Liabilities on the balance sheet, and was $0.5 million as of December 31, 2020.

E.    FERC ROE Complaints
NaNFour separate complaints were filed at the FERC by combinations of New England state attorneys general, state regulatory commissions, consumer advocates, consumer groups, municipal parties and other parties (collectively, the Complainants). In each of the first 3three complaints, filed on October 1, 2011, December 27, 2012, and July 31, 2014, respectively, the Complainants challenged the NETOs' base ROE of 11.14 percent that had been utilized since 2005 and sought an order to reduce it prospectively from the date of the final FERC order and for the separate 15-month complaint periods. In the fourth complaint, filed April 29, 2016, the Complainants challenged the NETOs' base ROE billed of 10.57 percent and the maximum ROE for transmission incentive (incentive cap) of 11.74 percent, asserting that these ROEs were unjust and unreasonable.

123


The ROE originally billed during the period October 1, 2011 (beginning of the first complaint period) through October 15, 2014 consisted of a base ROE of 11.14 percent and incentives up to 13.1 percent. On October 16, 2014, the FERC issued Opinion No. 531-A and set the base ROE at 10.57 percent and the incentive cap at 11.74 percent for the first complaint period. This was also effective for all prospective billings to customers beginning October 16, 2014. This FERC order was vacated on April 14, 2017 by the U.S. Court of Appeals for the D.C. Circuit (the Court).

All amounts associated with the first complaint period have been refunded, which totaled $38.9 million (pre-tax and excluding interest) at Eversource and reflected both the base ROE and incentive cap prescribed by the FERC order. The refund consisted of $22.4 million for CL&P, $13.7 million for NSTAR Electric and $2.8 million for PSNH.

Eversource has recorded a reserve of $39.1 million (pre-tax and excluding interest) for the second complaint period as of both December 31, 20202023 and 2019.2022. This reserve represents the difference between the billed rates during the second complaint period and a 10.57 percent base ROE and 11.74 percent incentive cap. The reserve consisted of $21.4 million for CL&P, $14.6 million for NSTAR Electric and $3.1 million for PSNH as of both December 31, 20202023 and 2019.2022.

On October 16, 2018, FERC issued an order on all 4four complaints describing how it intends to address the issues that were remanded by the Court. FERC proposed a new framework to determine (1) whether an existing ROE is unjust and unreasonable and, if so, (2) how to calculate a replacement ROE. Initial briefs were filed by the NETOs, Complainants and FERC Trial Staff on January 11, 2019 and reply briefs were filed on March 8, 2019. The NETOs' brief was supportive of the overall ROE methodology determined in the October 16, 2018 order provided the FERC does not change the proposed methodology or alter its implementation in a manner that has a material impact on the results.

The FERC order included illustrative calculations for the first complaint using FERC's proposed frameworks with financial data from that complaint. Those illustrative calculations indicated that for the first complaint period, for the NETOs, which FERC concludes are of average financial risk, the preliminary just and reasonable base ROE is 10.41 percent and the preliminary incentive cap on total ROE is 13.08 percent.

If the results of the illustrative calculations were included in a final FERC order for each of the complaint periods, then a 10.41 percent base ROE and a 13.08 percent incentive cap would not have a significant impact on our financial statements for all of the complaint periods. These preliminary calculations are not binding and do not represent what we believe to be the most likely outcome of a final FERC order.

129


On November 21, 2019, FERC issued Opinion No. 569 affecting the two pending transmission ROE complaints against the Midcontinent ISO (MISO) transmission owners, in which FERC adopted a new methodology for determining base ROEs. Various parties sought rehearing. On December 23, 2019, the NETOs filed supplementary materials in the NETOs' four pending cases to respond to this new methodology because of the uncertainty of the applicability to the NETOs' cases.

On May 21, 2020, the FERC issued its order in Opinion No. 569-A on the rehearing of the MISO transmission owners' cases, in which FERC again changed its methodology for determining the MISO transmission owners' base ROEs. Various parties appealed the MISO transmission owners' opinion. On November 19, 2020, the FERC issued Opinion No. 569-B denying rehearing of Opinion No. 569-A and reaffirmed the methodology previously adopted in Opinion No. 569-A. The new methodology differs significantly from the methodology proposed by FERC in its October 16, 2018 order to determine the NETOs' base ROEs in its four pending cases. FERC Opinion Nos. 569-A and 569-B were appealed to the Court. On August 9, 2022, the Court issued its decision vacating MISO ROE FERC Opinion Nos. 569, 569-A and 569-B and remanded to FERC to reopen the proceedings. The Court found that FERC’s development of the new return methodology was arbitrary and capricious due to FERC’s failure to offer a reasonable explanation for its decision to reintroduce the risk-premium financial model in its new methodology for calculating a just and reasonable return. At this time, Eversource cannot predict how and when FERC will address the Court’s findings on the remand of the MISO FERC opinions or any potential associated impact on the NETOs’ four pending ROE complaint cases.

Given the significant uncertainty regarding the applicability of the FERC opinions in the MISO transmission owners'owners’ two complaint cases to the NETOs'NETOs’ pending four complaint cases, Eversource concluded that there is no reasonable basis for a change to the reserve or recognized ROEs for any of the complaint periods at this time. As well, Eversource cannot reasonably estimate a range of any gain or loss for any of the four complaint proceedings at this time.

Eversource, CL&P, NSTAR Electric and PSNH currently record revenues at the 10.57 percent base ROE and incentive cap at 11.74 percent established in the October 16, 2014 FERC order.

A change of 10 basis points to the base ROE used to establish the reserves would impact Eversource’s after-tax earnings by an average of approximately $3 million for each of the four 15-month complaint periods.

F.     Eversource and NSTAR Electric Boston Harbor Civil ActionCL&P Regulatory Matters
In 2016, the United States AttorneyCL&P Tropical Storm Isaias Response Investigation: On April 28, 2021, PURA issued a final decision on behalf of the United States Army Corps of Engineers filed a civil action in the United States District Court for the District of Massachusetts against NSTAR Electric, HEEC, and the Massachusetts Water Resources Authority (togetherCL&P’s compliance with NSTAR Electric and HEEC, the "Defendants").  The action allegedits emergency response plan that the Defendantsconcluded CL&P failed to comply with certain permittingstorm performance standards and was imprudent in certain instances regarding its preparation for, and response to, Tropical Storm Isaias. Based on its findings, PURA ordered CL&P to adjust its future rates in a pending or future rate proceeding to reflect a monetary penalty in the form of a downward adjustment of 90 basis points in its allowed rate of return on equity (ROE), which is currently 9.25 percent. On July 14, 2021, PURA issued a final decision in a penalty proceeding that included an assessment of $28.6 million, consisting of a $28.4 million civil penalty for non-compliance with storm performance standards to be provided as credits on customer bills and a $0.2 million fine for violations of accident reporting requirements to be paid to the State of Connecticut’s general fund. The $28.4 million performance penalty was credited to customers on electric bills beginning on September 1, 2021 over a one-year period. The $28.4 million is the maximum statutory penalty amount under applicable Connecticut law in effect at the time of Tropical Storm Isaias, which is 2.5 percent of CL&P’s annual distribution revenues. The liability for the performance penalty was recorded as a current regulatory liability on CL&P’s balance sheet and as a reduction to Operating Revenues on the year ended December 31, 2021 statement of income.

CL&P Settlement Agreement: On October 1, 2021, CL&P entered into a settlement agreement with the DEEP, Office of Consumer Counsel, Office of the Attorney General and the Connecticut Industrial Energy Consumers, resolving certain issues that arose in then-pending regulatory proceedings initiated by PURA. PURA approved the settlement agreement on October 27, 2021. In the settlement agreement, CL&P agreed to provide a total of $65 million of customer credits, which were distributed based on customer sales over a two-month billing period from December 1, 2021 to January 31, 2022. CL&P also agreed to irrevocably set aside $10 million in a customer assistance fund to provide bill payment assistance to certain existing non-hardship and hardship customers carrying arrearages, as approved by PURA, with the objective of disbursing the funds prior to April 30, 2022. Those customers were provided with $10 million of bill forgiveness in the first quarter of 2022. CL&P recorded a current regulatory liability of $75 million on the balance sheet associated with the provisions of the settlement agreement, with a $65 million pre-tax charge as a reduction to Operating Revenues associated with the customer credits and a $10 million charge to Operations and Maintenance expense associated with the customer assistance fund on the year ended December 31, 2021 statement of income.

In exchange for the $75 million of customer credits and assistance, PURA’s interim rate reduction docket was resolved without findings. As a result of the settlement agreement, neither the 90 basis point reduction to CL&P’s return on equity introduced in PURA’s storm-related decision issued April 28, 2021, nor the 45 basis point reduction to CL&P’s return on equity included in PURA’s decision issued September 14, 2021 in the interim rate reduction docket, will be implemented. CL&P also agreed to freeze its current base distribution rates, subject to the customer credits described above, until no earlier than January 1, 2024. The rate freeze applied only to base distribution rates (including storm costs) and not to other rate mechanisms such as the retail rate components, rate reconciling mechanisms, formula rates and any other adjustment mechanisms. The rate freeze also did not apply to any cost recovery mechanism outside of the base distribution rates with regard to grid-modernization initiatives or any other proceedings that were either pending or that could be initiated during the rate freeze period, that could have placed additional obligations on CL&P. The approval of the settlement agreement satisfied the Connecticut statute of rate review requirements that requires electric utilities to file a distribution rate case within four years of the last rate case.

As part of the settlement agreement, CL&P agreed to withdraw with prejudice its pending appeals of PURA’s decisions dated April 28, 2021 and July 14, 2021 related to the placementStorm Isaias and agreed to waive its right to file an appeal and seek a judicial stay of the HEEC-owned electric distribution cable beneath Boston Harbor.  September 14, 2021 decision in the interim rate reduction docket. The settlement agreement assures that CL&P will have the opportunity to petition for and demonstrate the prudency of the storm costs incurred to respond to customer outages associated with Storm Isaias in a future ratemaking proceeding.

The parties reached a settlement pursuant to which HEEC agreed to install a new 115kV distribution cable across Boston Harbor to Deer Island, utilizing a different route, and remove portionscumulative pre-tax impact of the existing cable. Construction ofsettlement agreement and the new distribution cableStorm Isaias assessment imposed in PURA’s April 28, 2021 and July 14, 2021 decisions totaled $103.6 million, and the after-tax earnings impact was completed in August 2019 and removal of the portions of the existing cable was completed in January 2020. All issues surrounding the current permit from the United States Army Corps of Engineers are expected to be resolved, and subsequently, such litigation then dismissed with prejudice.

NSTAR Electric agreed to provide a rate base credit of $17.5$86.1 million, to the Massachusetts Water Resources Authorityor $0.25 per share, for the new cable. This negotiated credit resulted in the initial $17.5 million of construction costs on the new cable being expensed as incurred, all of which was fully expensed in 2018. In connection with the new cable that was placed into service, a corresponding ARO was recognized for approximately $32 million within Other Long-Term Liabilities on the Eversource and NSTAR Electric balance sheets as ofyear ended December 31, 2019.2021.

G.     Litigation and Legal Proceedings
Eversource, including CL&P, NSTAR Electric and PSNH, are involved in legal, tax and regulatory proceedings regarding matters arising in the ordinary course of business, which involve management's assessment to determine the probability of whether a loss will occur and, if probable, its best estimate of probable loss.  The Company records and discloses losses when these losses are probable and reasonably estimable, and discloses matters when losses are probable but not estimable or when losses are reasonably possible.  Legal costs related to the defense of loss contingencies are expensed as incurred.

14.     LEASES

Eversource, including CL&P, NSTAR Electric and PSNH, has entered into lease agreements as a lessee for the use of land, office space, service centers, vehicles, information technology, and equipment. These lease agreements are classified as either finance or operating leases and the liability and right-of-use asset are recognized on the balance sheet at lease commencement.  Leases with an initial term of 12 months or less are not recorded on the balance sheet and are recognized as lease expense on a straight-line basis over the lease term.

Eversource determines whether or not a contract contains a lease based on whether or not it provides Eversource with the use of a specifically identified asset for a period of time, as well as both the right to direct the use of that asset and receive the significant economic benefits of the asset. Eversource has elected the practical expedient to not separate non-lease components from lease components and instead to account for both as a single lease component, with the exception of the information technology asset class where the lease and non-lease components are separated.

The provisions of Eversource, CL&P, NSTAR Electric and PSNH lease agreements contain renewal options. The renewal options range from one year to twenty years. The renewal period is included in the measurement of the lease liability if it is reasonably certain that Eversource will exercise these renewal options.

For leases entered into or modified after the January 1, 2019 implementation date of the leases standard under Topic 842, the discount rate utilized for classification and measurement purposes as of the inception date of the lease is based on each company's collateralized incremental interest rate to borrow over a comparable term for an individual lease because the rate implicit in the lease is not determinable.

CL&P and PSNH entered into certain contracts for the purchase of energy that qualify as leases.  These contracts do not have minimum lease payments and therefore are not recognized as a lease liability on the balance sheet and are not reflected in the future minimum lease payments table below.  Expense related to these contracts is included as variable lease cost in the table below. The expense and long-term obligation for these contracts are also included in Note 13B, "Commitments and Contingencies - Long-Term Contractual Arrangements," to the financial statements.  

The components of lease cost, prior to amounts capitalized, are as follows:

17.     DIVIDEND RESTRICTIONS

Eversource parent's ability to pay dividends may be affected by certain state statutes, the ability of its subsidiaries to pay common dividends and the leverage restriction tied to its consolidated total debtindebtedness to total capitalization ratio requirement in its revolving credit agreements.  Pursuant to the joint revolving credit agreement of Eversource, CL&P, PSNH, NSTAR Gas, Yankee Gas, EGMA and Aquarion Water Company of Connecticut, the joint revolving credit agreement of Eversource and EGMA, and to the NSTAR Electric revolving credit agreement, Eversource is required to maintain consolidated total indebtedness to total capitalization ratio of no greater than 70 percent at the end of each fiscal quarter and each other company is required to maintain consolidated total indebtedness to total capitalization ratio of no greater than 65 percent at the end of each fiscal quarter. As of December 31, 2020,2023, all companies were in compliance with suchsuch covenant and in compliance with all such provisions of the revolving credit agreements that may restrict the payment of dividends as of December 31, 2020.2023.

The Retained Earnings balances subject to dividend restrictions were $4.61$4.14 billion for Eversource, $2.17$2.65 billion for CL&P, $2.53$3.14 billion for NSTAR Electric and $615.0$655.8 million for PSNH as of December 31, 2020.2023.

CL&P, NSTAR Electric and PSNH are subject to Section 305 of the Federal Power Act that makes it unlawful for a public utility to make or pay a dividend from any funds "properly included in its capital account." Management believes that this Federal Power Act restriction, as applied to CL&P, NSTAR Electric and PSNH, would not be construed or applied by the FERC to prohibit the payment of dividends from retained earnings for lawful and legitimate business purposes. In addition, certain state statutes may impose additional limitations on such companies and, including but not limited to, on NSTAR Gas, Yankee Gas, EGMA, Aquarion Water Company of Connecticut, Aquarion Water Company of Massachusetts and Aquarion Water Company of New Hampshire.Aquarion’s operating companies. Such state law restrictions do not restrict the payment of dividends from retained earnings or net income.

In 2022, Eversource issued 2,165,671 common shares, which resulted in proceeds of $509.2 million, net of issuance costs.

In June 2019, Eversource completed an equity offering consisting of 5,980,000 common shares issued directly by the Company and 11,960,000 common shares issuable pursuant to a forward sale agreement with an investment bank. Under the forward sale agreement, 11,960,000 common shares were borrowed from third parties and sold by the underwriters. The forward sale agreement allowed Eversource, at its election and prior to May 29, 2020, to physically settle the forward sale agreement by issuing common shares in exchange for net proceeds at the then-applicable forward sale price specified by the agreement (initially, $71.48 per share) or, alternatively, to settle the forward sale agreement in whole or in part through the delivery or receipt of shares or cash. The forward sale price was subject to adjustment daily based on a floating interest rate factor and would decrease in respect of certain fixed amounts specified in the agreement, such as dividends.

Eversource issued 6,000,000 common shares under the forward sale agreement in December 2019. On March 23, 2020, Eversource physically settled a portion of the forward sale agreement by delivering 1,500,000 common shares in exchange for net proceeds of $105.7 million. Subsequently, on March 26, 2020, Eversource physically settled the remaining portion of the forward sale agreement by delivering 4,460,000 common shares in exchange for net proceeds of $314.1 million. The forward sale price used to determine the cash proceeds received by Eversource was calculated based on the initial forward sale price, as adjusted in accordance with the forward sale agreement.

The March and June 2020 common share issuances of 5,960,000 and 6,000,000, respectively, resulted in total proceeds of $929.0$197.1 million, net of issuance costs. The June and December 2019 common share issuances of 5,980,000 and 6,000,000, respectively, resulted in total proceeds of $852.3 million. These issuances were reflected in shareholders’ equity and as financing activities on the statements of cash flows.

Issuances of shares under the forward sale agreement were classified as equity transactions. Accordingly, no amounts relating to the forward sale agreement were recorded in the financial statements until settlements took place. Prior to any settlements, the only impact of the forward sale agreement to the financial statements was the inclusion of incremental shares within the calculation of diluted EPS using the treasury stock method. See Note 21, "Earnings Per Share," to the financial statements for information on the forward sale agreement’s impact on the calculation of diluted EPS.

Eversource used the net proceeds received from the direct issuance of common shares and the net proceeds received from settlement of the forward sale agreement to repay short-term debt under the commercial paper program, to partially fund the purchase of the assets of CMA, to fund capital spending and clean energy initiatives, and for general corporate purposes.

Dividends on the preferred stock of CL&P and NSTAR Electric totaled $7.5 million for each of the years ended December 31, 2020, 20192023, 2022 and 2018.2021.  These dividends were presented as Net Income Attributable to Noncontrolling Interests on the Eversource statements of income. Noncontrolling Interest – Preferred Stock of Subsidiaries on the Eversource balance sheets totaled $155.6 million as of December 31, 20202023 and 2019.2022.  On the Eversource balance sheets, Common Shareholders' Equity was fully attributable to Eversource parent and Noncontrolling Interest – Preferred Stock of Subsidiaries was fully attributable to the noncontrolling interest.

For the years ended December 31, 2020, 20192023, 2022 and 2018,2021, there was no change in ownership of the common equity of CL&P and NSTAR Electric.  

21.     EARNINGSEARNINGS/(LOSS) PER SHARE

Basic EPSearnings/(loss) per share is computed based upon the weighted average number of common shares outstanding during each period.  Diluted EPSearnings/(loss) per share is computed on the basis of the weighted average number of common shares outstanding plus the potential dilutive effect of certain share-based compensation awards and the equity forward sale agreement, as if they were converted into outstanding common shares.  The dilutive effect of unvested RSU and performance share awards as well as the equity forward sale agreement, is calculated using the treasury stock method.  RSU and performance share awards are included in basic weighted average common shares outstanding as of the date that all necessary vesting conditions have been satisfied.  

As described in Note 18, "Common Shares," earnings per share dilution, if any, related to the forward sale agreement is determined under the treasury stock method until settlement of the forward sale agreement. Under this method, the number of Eversource common shares used in calculating diluted EPS is deemed to be increased by the excess, if any, of the number of shares that would be issued upon physical settlement of the forward sale agreement less the number of shares that would be purchased by Eversource in the market (based on the average market price during the same reporting period) using the proceeds receivable upon settlement (based on the adjusted forward sale price at the end of that reporting period). Share dilution occurs when the average market price of Eversource's common shares is higher than the adjusted forward sale price. Eversource physically settled all remaining shares under the forward sale agreement as of March 26, 2020.

For the yearyears ended December 31, 2020,2023, 2022 and 2021, there were 39,560no antidilutive share awards excluded from the EPS computation, as their impact would have been antidilutive. Antidilutive shares pertained to a purchase option extended to underwriters in connection with Eversource's common share issuance on June 15, 2020. See Note 18, "Common Shares," for further information. There were 0 antidilutive share awards excluded from the computation for the years ended December 31, 2019 or 2018.computation.

22.    REVENUES

Revenue is recognized when promised goods or services (referred to as performance obligations) are transferred to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. A five-step model is used for recognizing and measuring revenue from contracts with customers, which includes identifying the contract with the customer, identifying the performance obligations promised within the contract, determining the transaction price (the amount of consideration to which the company expects to be entitled), allocating the transaction price to the performance obligations and recognizing revenue when (or as) the performance obligation is satisfied.

Retail Tariff Sales: Regulated utilities provide products and services to their regulated customers under rates, pricing, payment terms and conditions of service, regulated by each state regulatory agency. The arrangement whereby a utility provides commodity service to a customer for a price approved by the respective state regulatory commission is referred to as a tariff sale contract, and the tariff governs all aspects of the provision of regulated services by utilities. The majority of revenue for Eversource, CL&P, NSTAR Electric and PSNH is derived from regulated retail tariff sales for the sale and distribution of electricity, natural gas and water to residential, commercial and industrial retail customers.

The utility's performance obligation for the regulated tariff sales is to provide electricity, natural gas or water to the customer as demanded. The promise to provide the commodity represents a single performance obligation, as it is a promise to transfer a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer. Revenue is recognized over time as the customer simultaneously receives and consumes the benefits provided by the utility, and the utility satisfies its performance obligation. Revenue is recognized based on the output method as there is a directly observable output to the customer (electricity, natural gas or water units delivered to the customer and immediately consumed). Each Eversource utility is entitled to be compensated for performance completed to date (service taken by the customer) until service is terminated.

In regulated tariff sales, the transaction prices are the rates approved by the respective state regulatory commissions.  In general, rates can only be changed through formal proceedings with the state regulatory commissions. These rates are designed to recover the costs to provide service to customers and include a return on investment. Regulatory commission-approved tracking mechanisms are included in these rates and are also used to recover, on a fully-reconciling basis, certain costs, such as the procurement of energy supply, retail transmission charges, energy efficiency program costs, net metering for distributed generation, and restructuring and stranded costs.costs, among others. These tracking mechanisms result in rates being changed periodically to ensure recovery of actual costs incurred.incurred and the refund of any overcollection of costs.

CustomersElectric customers may elect to purchase electricity from each Eversource electric utility or may contract separately with a competitive third party supplier. Certain eligible natural gas customers may elect to purchase natural gas from each Eversource natural gas utility or may contract separately with a gas supply operator. Revenue is not recorded for the sale of the electricity or the natural gas commodity to customers who have contracted separately with these suppliers, only the delivery to a customer, as the utility is acting as an agent on behalf of the third party supplier.

Wholesale Transmission Revenues:  The Eversource electric transmission-owning companies (CL&P, NSTAR Electric and PSNH) each own and maintain transmission facilities that are part of an interstate power transmission grid over which electricity is transmitted throughout New England. CL&P, NSTAR Electric and PSNH, as well as most other New England utilities, are parties to a series of agreements that provide for coordinated planning and operation of the region's transmission facilities and the rules by which they acquire transmission services.  The Eversource electric transmission-owning companies have a combination of FERC-approved regional and local formula rates that work in tandem to recover all their transmission costs. These rates are part of the ISO-NE Tariff. Regional rates recover the costs of higher voltage transmission facilities that benefit the region and are collected from all New England transmission customers, including the Eversource distribution businesses. Eversource's local rates recover the companies' totalcosts of transmission revenue requirements, less revenues received from regional rates and other sources,facilities that do not provide a benefit to the region, and are collected from Eversource's distribution businesses and other transmission customers. The distribution businesses of Eversource, in turn, recover the FERC approved charges from retail customers through annual or semiannual tracking mechanisms, which are retail tariff sales.

The utility's performance obligation for regulated wholesale transmission sales is to provide transmission services to the customer as demanded. The promise to provide transmission service represents a single performance obligation. The transaction prices are the transmission rate formulas as defined by the ISO-NE Tariff and are regulated and established by FERC. Wholesale transmission revenue is recognized over time as the performance obligation is completed, which occurs as transmission services are provided to customers. The revenue is recognized based on the output method. Each Eversource utility is entitled to be compensated for performance completed to date (e.g., use of the transmission system by the customer).

Wholesale Market Sales Revenues: Wholesale market sales transactions include sales of energy and energy-related products into the ISO-NE wholesale electricity market, sales of natural gas to third party marketers, and also the sale of RECs to various counterparties. ISO-NE oversees the region's wholesale electricity market and administers the transactions and terms and conditions, including payment terms, which are established in the ISO-NE tariff, between the buyers and sellers in the market. Pricing is set by the wholesale market. The wholesale transactions in the ISO-NE market occur on a day-ahead basis or a real-time basis (daily) and are, therefore, short-term. Transactions are tracked and reported by ISO-NE net by the hour, which is the net hourly position of energy sales and purchases by each market participant. The performance obligation for ISO-NE energy transactions is defined to be the net by hour transaction. Revenue is recognized when the performance obligation for these energy sales transactions is satisfied, which is when the sale occurs and the energy is transferred to the customer. For sales of natural gas, transportation, and natural gas pipeline capacity to third party marketers, revenue is recognized when the performance obligation is satisfied at the point in time the sale occurs and the natural gas or related product is transferred to the marketer. RECs are sold to various counterparties, and revenue is recognized when the performance obligation is satisfied upon transfer of title to the customer through the New England Power Pool Generation Information System. Wholesale transactions also include the sale of CL&P’s, NSTAR Electric’s and PSNH’s transmission rights associated with their proportionate equity ownership share in the transmission lines of the Hydro-Québec system in Canada.

Other Revenues from Contracts with Customers: Other revenues from contracts with customers primarily include property rentals that are not deemed leases. These revenues are generally recognized on a straight-line basis over time as the service is provided to the customer. Other revenues also include revenues from Eversource's service company, which is eliminated in consolidation.

Amortization of/(Reserve for) Revenues Subject to Refund:Eversource has recorded a regulatory liability, A reserve is recorded as a reduction to revenues to reflect the difference between the 35 percent federal corporate income tax rate included in rates chargedwhen future refunds to customers andare deemed probable. The reserve is reversed as refunds are provided to customers in rates. Amortization of Revenues Subject to Refund within the 21 percent federal corporate income tax rate, effective January 1, 2018Electric Distribution segment in 2022 represents the reversal of a 2021 reserve at CL&P established to provide bill credits to customers as a result of the Tax Cutssettlement agreement on October 1, 2021 and Jobs Acta storm performance penalty assessed by PURA. The reserve was reversed as customer credits were distributed to CL&P’s customers in retail electric rates. Total customer credits as a result of 2017, until rates billed to customers reflect the lower federal tax rate. The Connecticut water business has not yet reflected the change in the federal corporate income tax rate in distribution rates2021 settlement and continues to accrue the regulatory liability. CL&P and Yankee Gas each have fully refunded this regulatory liability by the endcivil penalty of 2018 and 2020, respectively, and in 2019, PSNH began$93.4 million were recorded as a reserve for revenues subject to refund thiswithin current regulatory liabilityliabilities and reflected as a reduction to customers in rates. NSTAR ElectricOperating Revenues on the 2021 income statement. The settlement amount of $65 million was refunded over a two-month billing period from December 1, 2021 to January 31, 2022 and NSTAR Gas were not required to make refunds to customers for the higher federal corporate income tax rate billed to customers in thecivil penalty of $28.4 million was refunded over a one year billing period, between Januarywhich began September 1, 2018 to the effective dates of each company's 2018 rate changes. EGMA will begin refunding this amount in November 2021.

Alternative Revenue Programs: In accordance with accounting guidance for rate-regulated operations, certain of Eversource's utilities' rate making mechanisms qualify as alternative revenue programs (ARPs) if they meet specified criteria, in which case revenues may be recognized prior to billing based on allowed levels of collection in rates. Eversource's utility companies recognize revenue and record a regulatory asset or liability once the condition or event allowing for the automatic adjustment of future rates occurs. ARP revenues include both the recognition of the deferral adjustment to ARP revenues, when the regulator-specified condition or event allowing for additional billing or refund has occurred, and an equal and offsetting reversal of the ARP deferral to revenues as those amounts are reflected in the price of service in subsequent periods.

139


Eversource’s ARPs include the revenue decoupling mechanism, and the annual reconciliation adjustment to transmission formula rates, described below.

and certain capital tracker mechanisms. Certain Eversource electric, natural gas and water companies, including CL&P and NSTAR Electric, have revenue decoupling mechanisms approved by a regulatory commission (decoupled companies). Decoupled companies’ distribution revenues are not directly based on sales volumes. The decoupled companies reconcile their annual base distribution rate recovery to pre-established levels of baseline distribution delivery service revenues, with any difference between the allowed level of distribution revenue and the actual amount realized adjusted through subsequent rates.

The transmission formula rates provide for the annual reconciliation and recovery or refund of estimated costs to actual costs.  The financial impacts of differences between actual and estimated costs are deferred for future recovery from, or refund to, transmission customers.  This transmission deferral reconciles billed transmission revenues to the revenue requirement for our transmission businesses.

Other Revenues: Other Revenues include certain fees charged to customers that are not considered revenue from contracts with customers. Other revenues also include lease revenues under lessor accounting guidance of $4.3$4.6 million ($0.7 million at CL&P and $2.5 million at NSTAR Electric), $4.0 million ($0.8 million at CL&P and $2.7$2.5 million at NSTAR Electric), and $4.4$4.8 million, ($1.00.8 million at CL&P and $2.7$3.1 million at NSTAR Electric) for the years ended December 31, 20202023, 2022 and 2019,2021, respectively.

Intercompany Eliminations: Intercompany eliminations are primarily related to the Eversource electric transmission revenues that are derived from ISO-NE regional transmission charges to the distribution businesses of CL&P, NSTAR Electric and PSNH that recover the costs of the wholesale transmission business, and revenues from Eversource's service company. Intercompany revenues and expenses between the Eversource wholesale transmission businesses and the Eversource distribution businesses and from Eversource's service company are eliminated in consolidation and included in "Eliminations" in the tabletables above.

Receivables: Receivables, Net on the balance sheet includeprimarily includes trade receivables from our retail customers and receivables arising from ISO-NE billingcustomers related to wholesale transmission contracts, and wholesale market transactions, sales, of natural gas and capacity to marketers, sales of RECs, and property rentals. In general, retail tariff customers and wholesale transmission customers are billed monthly and the payment terms are generally due and payable upon receipt of the bill.

Unbilled Revenues: Unbilled Revenues on the balance sheet represent estimated amounts due from retail customers for electricity, natural gas or water delivered to customers but not yet billed. The utility company has satisfied its performance obligation and the customer has received and consumed the commodity as of the balance sheet date, and therefore, the utility company records revenue for those services in the period the services were provided. Only the passage of time is required before the company is entitled to payment for the satisfaction of the performance obligation. Payment from customers is due monthly as services are rendered and amounts are billed. Actual amounts billed to customers when meter readings become available may vary from the estimated amount.

Unbilled revenues are recognized by allocating estimated unbilled sales volumes to the respective customer classes, and then applying an estimated rate by customer class to those sales volumes. Unbilled revenue estimates reflect seasonality, weather, customer usage patterns, customer rates in effect for customer classes, and the timing of customer billing. The companies that have a decoupling mechanism record a regulatory deferral to reflect the actual allowed amount of revenue associated with their respective decoupled distribution rate design.

Practical Expedients: Eversource has elected practical expedients in the accounting guidance that allow the company to record revenue in the amount that the company has a right to invoice, if that amount corresponds directly with the value to the customer of the company's performance to date, and not to disclose related unsatisfied performance obligations. Retail and wholesale transmission tariff sales fall into this category, as these sales are recognized as revenue in the period the utility provides the service and completes the performance obligation, which is the same as the monthly amount billed to customers. There are no other material revenue streams for which Eversource has unsatisfied performance obligations.

23.     SEGMENT INFORMATION

Eversource is organized into the Electric Distribution, Electric Transmission, Natural Gas Distribution and Water Distribution reportable segments and Other based on a combination of factors, including the characteristics of each segments' services, the sources of operating revenues and expenses and the regulatory environment in which each segment operates.  These reportable segments represent substantially all of Eversource's total consolidated revenues.  Revenues from the sale of electricity, natural gas and water primarily are derived from residential, commercial and industrial customers and are not dependent on any single customer.  The Electric Distribution reportable segment includes the results of PSNH's generation facilities prior to sales in January and August 2018, and NSTAR Electric's solar power facilities. Eversource's reportable segments are determined based upon the level at which Eversource's chief operating decision maker assesses performance and makes decisions about the allocation of company resources.  

The remainder of Eversource's operations is presented as Other in the tables below and primarily consists of 1) the equity in earnings of Eversource parent from its subsidiaries and intercompany interest income, both of which are eliminated in consolidation, and interest expense related to the debt of Eversource parent, 2) the revenues and expenses of Eversource Service, most of which are eliminated in consolidation, 3) the operations of CYAPC and YAEC, 4) Eversource Water Ventures, Inc., parent company of Aquarion, 5) the results of other unregulated subsidiaries, which are not part of its core business, and 6)5) Eversource parent's equity ownership interests that are not consolidated, which primarily include the offshore wind business, a natural gas pipeline owned by Enbridge, Inc., and a renewable energy investment fund.fund that was liquidated in 2023.

In the ordinary course of business, Yankee Gas, NSTAR Gas and EGMA purchase natural gas transmission services from the Enbridge, Inc. natural gas pipeline project described above. These affiliate transaction costs total $77.7 million annually and are classified as Purchased Power, FuelPurchased Natural Gas and Transmission on the Eversource statements of income.

Each of Eversource's subsidiaries, including CL&P, NSTAR Electric and PSNH, has 1one reportable segment.

24.     ACQUISITION OF ASSETS OF COLUMBIA GAS OF MASSACHUSETTS

On October 9, 2020, Eversource acquired certain assets and liabilities that comprised NiSource’s natural gas distribution business in Massachusetts, which was previously doing business as CMA, pursuant to an asset purchase agreement (the Agreement) entered into on February 26, 2020 between Eversource and NiSource Inc. (NiSource). The cash purchase price was $1.1 billion, plus a target working capital amount of $69.6 million, which is subject to adjustment to reflect actual working capital as of the closing date that has not yet been finalized. Eversource financed the acquisition through a combination of debt and equity issuances in a ratio that was consistent with our consolidated capital structure. The natural gas distribution assets acquired from CMA were assigned to EGMA, an indirect wholly-owned subsidiary of Eversource formed in 2020. The LNG assets acquired from CMA were assigned to Hopkinton LNG Corp. EGMA distributes natural gas to approximately 332,000 residential, commercial and industrial customers with over 5,000 miles of natural gas distribution pipeline across more than 60 communities in Massachusetts, adding to the approximately 303,000 natural gas customers that Eversource already serves in Massachusetts.

The transaction required approval by the DPU, the Maine Public Utilities Commission, the FERC, and the Federal Communications Commission, and review under the Hart-Scott-Rodino Act.

The liabilities assumed by Eversource under the Agreement specifically excluded any liabilities (past or future) arising out of, or related to, the fires and explosions that occurred on September 13, 2018 in Lawrence, Andover and North Andover, Massachusetts related to the delivery of natural gas by CMA, including certain subsequent events, all as described and in the DPU's Order on Scope dated December 23, 2019 (D.P.U. 19-141) (the Greater Lawrence Incident or GLI). The liabilities assumed also excluded any further emergency events prior to the closing of the acquisition related to the restoration and reconstruction with respect to the GLI, including any losses arising out of, or related to, any litigation, demand, cause of action, claim, suit, investigation, proceeding, indemnification agreements or rights. Eversource did not assume any of CMA's or NiSource Inc.'s third party debt obligations or notes payable.

Rate Settlement Agreement: On October 7, 2020, the DPU approved a rate settlement agreement with Eversource, EGMA, NiSource, Bay State, the Massachusetts Attorney General's Office, the DOER and the Low-Income Weatherization and Fuel Assistance Program Network, which requested approval of the February 26, 2020 Agreement, as well as a rate stabilization plan, among other items. The settlement agreement included an authorized regulatory ROE of 9.70 percent as of January 1, 2021, a 53.25 percent equity component of its capital structure, and established rate base equal to $995 million as of the closing on October 9, 2020.

The approved rate stabilization plan includes base distribution rate increases of $13 million on November 1, 2021 and $10 million on November 1, 2022. The settlement agreement includes 2 rate base resets during an eight-year rate plan, occurring on November 1, 2024 and November 1, 2027. The 2 rate base resets adjust distribution rates to account for capital additions (including the roll-in of GSEP capital additions), depreciation expense, property taxes, and return on rate base for capital additions placed into service through December 31, 2023, for the first rate base reset occurring on November 1, 2024, and through December 31, 2026, for the second rate base reset occurring on November 1, 2027. Notwithstanding the 2 distribution rate increases, the 2 rate base reset provisions, and potential adjustments for qualifying exogenous events, EGMA agreed not to file for an increase or redesign of distribution base rates effective prior to November 1, 2028.

The settlement agreement also permits EGMA to seek recovery of both transaction and integration costs as a result of the asset acquisition after December 31, 2026, subject to DPU review and approval, and subject to certain conditions, such as demonstrating savings resulting from the acquisition.

Preliminary Purchase Price Allocation: The allocation of the total purchase price to the estimated fair values of the assets acquired and liabilities assumed has been determined based on the accounting guidance for fair value measurements, which defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The preliminary allocation of the cash purchase price as of October 9, 2020 is as follows:
(Millions of Dollars)
Current Assets$145 
Restricted Cash57 
PP&E1,195 
Goodwill42 
Other Noncurrent Assets, excluding Goodwill128 
Other Current Liabilities(81)
Other Noncurrent Liabilities(317)
Cash Purchase Price$1,169 

The fair values of CMA's assets and liabilities were determined based on significant estimates and assumptions, including Level 3 inputs, that are judgmental in nature. The allocation of the total purchase price includes adjustments to reflect plant that will not earn a return and to reduce rate base to the allowed $995 million as specified in the rate settlement agreement. Eversource also recorded a $6.7 million liability for the future refund to customers for CMA's overcollection of the lower income tax rate beginning in 2018.

The excess of the purchase price over the estimated fair values of the assets acquired and liabilities assumed was recognized as goodwill. The goodwill reflects the value paid by Eversource primarily for expanding its natural gas infrastructure within its existing jurisdiction. The goodwill resulting from the acquisition has been assigned to the Natural Gas Distribution reporting unit.
136



Under the terms of the settlement agreement, a portion of the proceeds of the sale due to NiSource was withheld and used to establish an Energy Relief Fund comprised of two components, an Arrearage Forgiveness Fund and a fund which is restricted for energy efficiency and clean energy measures in the Merrimack Valley. As a result, Eversource funded restricted cash accounts and established a liability totaling $56.8 million on the acquisition date. By December 31, 2020, $15.4 million of the Arrearage Forgiveness Fund was credited back to customers and the remainder was paid back to NiSource. The purchase price included in investing cash outflows on the statement of cash flows of $1.11 billion reflects the payment to NiSource, excluding the restricted cash funds.

Pro Forma Financial Information: The following unaudited pro forma financial information reflects the pro forma combined results of operations of Eversource and the CMA business acquired and reflects the amortization of purchase price adjustments assuming the acquisition had taken place on January 1, 2019. The unaudited pro forma financial information has been presented for illustrative purposes only and is not necessarily indicative of the consolidated results of operations that would have been achieved or the future consolidated results of operations of Eversource. Pro forma net income excludes the impact of assets and liabilities not assumed by Eversource, such as amounts directly associated with the GLI incident, and non-recurring costs associated with the transaction.

Revenues and Net Income: The impact of CMA on Eversource's accompanying consolidated statement of income included operating revenues of $154.8 million and net income attributable to common shareholders of $13.9 million for the year ended December 31, 2020.

Transactions recognized separately from the business combination: Eversource has entered into a Transition Services Agreement (TSA) with NiSource, under which NiSource is providing certain administrative functions. Eversource has recorded $15.9 million in Operating Expenses on the statement of income related to TSA and pre-TSA costs in the fourth quarter of 2020. In addition, Eversource recorded $2.0 million in Energy Efficiency expense related to the implementation of new energy efficiency programs as specified in the rate settlement agreement.

25.    GOODWILL

In a business combination, the excess of the purchase price over the estimated fair values of the assets acquired and liabilities assumed
is recognized as goodwill. The following table presents Eversource’s goodwill by reportable segment:

Balance as of December 31, 2023$2,543.6 $576.8 $451.0 $960.7 $4,532.1 

Eversource completed the acquisition of TWC on October 3, 2022, resulting in the addition of $44.8 million of goodwill, all of which was allocated to the Water Distribution reporting unit. Eversource completed the acquisition of NESC on December 1, 2021, resulting in the addition of $22.2 million of goodwill, which included measurement period increases in 2022 totaling $0.5 million. Eversource completed two water acquisitions in 2023, resulting in the addition of $9.5 million of goodwill. The goodwill was allocated to the Water Distribution reporting unit. For further information on the acquisitions of TWC and NESC, see Note 18, “Common Shares,” to the financial statements.

Goodwill is evaluated for impairment at least annually and more frequently if indicators of impairment arise. In accordance with the accounting standards, if the fair value of a reporting unit is less than its carrying value (including goodwill), the goodwill is tested for impairment. Goodwill is not subject to amortization, however is subject to a fair value based assessment for impairment at least annually and whenever facts or circumstances indicate that there may be an impairment.  A resulting write-down, if any, would be charged to Operating Expenses.   

In assessing goodwill for impairment, an entity is permitted to first assess qualitatively whether it is more likely than not that goodwill impairment exists as of the annual impairment test date. A quantitative impairment test is required only if it is concluded that it is more likely than not that a reporting unit’s fair value is less than it’s carrying amount. The annual goodwill assessment included a qualitative evaluation of multiple factors that impact the fair value of the reporting units, including general, macroeconomic and market conditions, and entity-specific assumptions that affect the future cash flows of the reporting units. Key considerations include discount rates, utility sector market performance and merger transaction multiples, the Company's share price and credit ratings, analyst reports, financial performance, cost and risk factors, internal estimates and projections of future cash flows and net income, long-term strategy, the timing and outcome of rate cases, and recent regulatory and legislative proceedings.

Eversource's reporting units for the purpose of testing goodwill are Electric Distribution, Electric Transmission, Natural Gas Distribution and Water Distribution. These reporting units are consistent with the operating segments underlying the reportable segments identified in Note 23, "Segment Information," to the financial statements.

Eversource completed the CMA asset acquisition on October 9, 2020, resulting in the addition of approximately $42 million of goodwill, which was allocated to the Natural Gas Distribution reporting unit. On July 31, 2020, Eversource sold its water system and treatment plant that supplies water to the towns of Hingham, Hull and North Cohasset to the town of Hingham, Massachusetts, resulting in a reduction to goodwill of $23.6 million. This goodwill was previously reflected in the Water Distribution reporting unit.

Eversource completed its annual goodwill impairment testassessment for the Electric Distribution, Electric Transmission, Natural Gas Distribution and Water Distribution reporting units as of October 1, 20202023 and determined that 0no impairment existed. There were no events subsequent to October 1, 20202023 that indicated impairment of goodwill. The annual goodwill assessment included an evaluation of the Company's share price and credit ratings, analyst reports, financial performance, cost and risk factors, long-term strategy, growth and future projections, as well as macroeconomic, industry and market conditions.  This evaluation required the consideration of several factors that impact the fair value of the reporting units, including conditions and assumptions that affect the future cash flows of the reporting units. Key considerations include discount rates, utility sector market performance and merger transaction multiples, and internal estimates of future cash flows and net income.

Management, on behalf of Eversource, CL&P, NSTAR Electric and PSNH, is responsible for establishing and maintaining adequate internal controls over financial reporting.  The internal control framework and processes have been designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.  There are inherent limitations of internal controls over financial reporting that could allow material misstatements due to error or fraud to occur and not be prevented or detected on a timely basis by employees during the normal course of business.  Additionally, internal controls over financial reporting may become inadequate in the future due to changes in the business environment.  Under the supervision and with the participation of the principal executive officer and principal financial officer, an evaluation of the effectiveness of internal controls over financial reporting was conducted based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  Based on this evaluation under the framework in COSO, management concluded that internal controls over financial reporting at Eversource, CL&P, NSTAR Electric and PSNH were effective as of December 31, 2020.2023.

Management, on behalf of Eversource, CL&P, NSTAR Electric and PSNH, evaluated the design and operation of the disclosure controls and procedures as of December 31, 20202023 to determine whether they are effective in ensuring that the disclosure of required information is made timely and in accordance with the Securities Exchange Act of 1934 and the rules and regulations of the SEC.  This evaluation was made under management's supervision and with management's participation, including the principal executive officer and principal financial officer as of the end of the period covered by this Annual Report on Form 10-K.  There are inherent limitations of disclosure controls and procedures, including the possibility of human error and the circumventing or overriding of the controls and procedures.  Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.  The principal executive officer and principal financial officer have concluded, based on their review, that the disclosure controls and procedures of Eversource, CL&P, NSTAR Electric and PSNH are effective to ensure that information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934 (i) is recorded, processed, summarized, and reported within the time periods specified in SEC rules and regulations and (ii) is accumulated and communicated to management, including the principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosures.

On October 9, 2020, Eversource completed the acquisition of certain assets and liabilities that comprised NiSource’s natural gas distribution business in Massachusetts (formerly Columbia Gas of Massachusetts (CMA)). The natural gas distribution assets acquired from CMA were assigned to EGMA and are part of the natural gas distribution segment. As of December 31, 2020, Eversource management has excluded EGMA from its evaluation of disclosure controls and procedures and management’s report on internal controls over financial reporting.

There have been no changes in internal controls over financial reporting for Eversource, CL&P, NSTAR Electric and PSNH during the quarter ended December 31, 20202023 that have materially affected, or are reasonably likely to materially affect, internal controls over financial reporting.

Item 9B.    Other Information

During the quarter ended December 31, 2023, none of the Company’s directors or officers adopted, modified, or terminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement,” as such terms are defined under Item 408 of Regulation S-K.

No additional information is required to be disclosed under this item as of December 31, 2020,2023, as this information has been previously disclosed in applicable reports on Form 8-K during the fourth quarter of 2020.2023.

COMPENSATION DISCUSSION AND ANALYSIS

CL&P is a wholly-owned subsidiary of Eversource Energy.  Its board of directors consists entirely of executive officers of Eversource Energy system companies.  CL&P does not have a compensation committee, and the Compensation Committee of Eversource Energy's Board of Trustees determines compensation for the executive officers of CL&P, including their salaries, annual incentive awards and long-term incentive awards. All of CL&P’s “Named Executive Officers,” as defined below, also serve as officers of Eversource Energy and one or more other subsidiaries of Eversource Energy.  Compensation set by the Compensation Committee of Eversource Energy (the Committee) and set forth herein is for services rendered to Eversource Energy and its subsidiaries by such officers in all capacities.

This Compensation Discussion and Analysis (CD&A) provides information about Eversource Energy’s compensation principles, objectives, plans, policies and actions for the Named Executive Officers. The discussion describes the specific components used in Eversource Energy’s compensation programs and approach to executive compensation, how Eversource Energy measures performance, and how Eversource Energy’s compensation principles were applied to compensation awards and decisions that were made by the Compensation Committee for the Named Executive Officers, as presented in the tables and narratives that follow. Given the unprecedented events of the past year, this discussion also describes how Eversource Energy effectively responded to the COVID-19 pandemic to safeguard Eversource Energy’s employees, customers and the communities that Eversource Energy serves, how the Compensation Committee considered the effects of the pandemic in its compensation decisions and how Eversource Energy worked to increase diversity in the workforce and raise awareness of the need for racial justice in our society. While this discussion focuses primarily on 2020 information, it also addresses decisions that were made in prior periods to the extent that these decisions are relevant to the full understanding of Eversource Energy’s compensation programs and the decisions that were made regarding 2020 performance. The CD&A also contains an assessment of performance measured against established 2020 goals and additional accomplishments, the compensation awards made by the Compensation Committee, and other information relating to Eversource Energy’s compensation programs, including:

Summary of 2020 Accomplishments

2020 and the COVID-19 Pandemic

From the beginning of the COVID-19 pandemic, Eversource Energy set out to continue to focus first and foremost on the safety and well-being of Eversource Energy stakeholders, to do for each of the groups noted below what Eversource Energy might be able to do in order to help them navigate through the effects of the pandemic and to assist Eversource Energy customers, employees, the people and organizations who live in and operate in the communities Eversource Energy serves, the society we live in, and you, Eversource Energy shareholders, in navigating the effects of the pandemic. Eversource Energy acted boldly and decisively as COVID-19 emerged as a public health crisis, and immediately implemented many changes to the way Eversource Energy conducts business, while continuing to remain focused on operational and financial performance.

The results and actions taken that Eversource Energy reports in this CD&A relate to 2020 performance in totality, some of which were specifically in response to the pandemic, and which have hopefully made living in a pandemic environment a little more tolerable. These include:

For Eversource Energy customers – Eversource Energy took steps to ensure that any personal contact between Eversource Energy employees (both in the field and those working remotely) and customers was performed safely and in accordance with all public health guidelines to reduce to the greatest extent possible the risk of transmission of the virus. Eversource Energy restored service following a substantial number of storms in a safe and effective manner, instituted a voluntary moratorium on customer shutoffs for non-payment, and offered broad payment and arrearage forgiveness plans to provide assistance from the economic pressures impacting Eversource Energy customers. Eversource Energy also made communicating with the Company easier, including the implementation of a new 24-hour call center, a dedicated team set up to help small business customers apply for COVID-19 related federal assistance, and the continuation of industry-leading energy efficiency programs done by quickly moving to virtual energy audits.

For Eversource Energy’s communities – Eversource Energy continued support to communities through volunteer activity and virtual events, with employees contributing over 26,000 hours to volunteerism, and contributed $8.1 million in sponsoring or supporting the many events noted in this CD&A. Eversource Energy Sustainability accomplishments are making a difference in making Eversource Energy communities a healthier place to live. Please see the disclosures in the 2020 Sustainability/ESG section under the headings Community and Awards.

For society – Beyond the pandemic, 2020 saw a heightened focus on the criticality of racial equity and justice. In response, Eversource Energy increased efforts to raise awareness of the need for social and racial justice along with related efforts to further diversity, equity
141


and inclusion in the workplace and workforce and help support the vision for racial justice. Eversource Energy’s racial equity task force, focused town hall discussions, and learning hub on racial and social justice speak to this commitment.

For Eversource Energy’s employees – Eversource Energy responded to the pandemic very quickly, taking the lead to implement work from home practices at the very beginning stage of the crisis, making numerous changes to work practices as a direct result of the pandemic, and continuing career development and company-paid educational opportunities for employees. Over 800 new Eversource Gas Company of Massachusetts employees, formerly Columbia Gas of Massachusetts (Columbia Gas) employees, were successfully on-boarded. No employees, whether from Columbia Gas or otherwise, lost their jobs due to the pandemic. Eversource Energy has also continued open, regular and transparent communications with employees, and has worked in close communication and cooperation with union leadership to keep employees safe and help them continue to grow. The partnership with union leadership has been instrumental and essential in helping to deal with the many challenges of 2020.

The sections within this CD&A titled “2020 Financial and Operational Accomplishments” and “2020 Annual Incentive Program Assessment” provide additional information with respect to some of the other actions taken by Eversource throughout the year in response to the pandemic.

Changes to 2021 Executive Compensation Programs

Due to the hardships experienced by Eversource Energy’s customers and communities as a result of COVID-19 and the extended outages that took place in CL&P’s service territory in 2020 following Storm Isaias, and in spite of excellent overall performance by Eversource Energy’s executives in 2020, the Compensation Committee determined that it would freeze base salaries for the senior executive officers, including the Named Executive Officers, at 2020 levels, rather than provide market based base salary increases. In addition, in Eversource Energy’s engagement sessions with shareholders, Eversource Energy received comments relative to the 50/50 mix of RSUs and Performance Shares in the long-term incentive program. As a result, the Committee revised the Performance Share Program in response to these shareholder comments and to further align Eversource Energy’s compensation programs with the Committee’s pay for performance philosophy, such that 75 percent of the 2021 – 2023 Program’s long-term incentive opportunity will consist of Performance Shares and 25 percent will consist of RSUs.

2020 Performance Assessment – COVID-19

With regard to the performance goals established by the Committee prior to the spread of the virus and whether changes to those goals should be considered as a result of the pandemic, the Committee discussed the established performance goals throughout its 2020 meetings, and concluded that it would not change them, as it determined that despite the additional challenges, the Operating Plan and related performance goals could still be executed under the direction and oversight of Eversource Energy’s Chief Executive Officer and his executive team without revision.

2020 Financial and Operational Accomplishments

In 2020, Eversource Energy continued to outperform its peers financially, strengthened its position as a leader in ESG, and met or exceeded all of the goals set by the Committee, all while keeping Eversource employees and customers safe. The following is a summary of some of the most important accomplishments in 2020:

FINANCIAL PERFORMANCE: 2020 earnings per share equaled $3.55 per share, and non-GAAP earnings per share equaled $3.64; non-GAAP earnings excludes transactional costs relating to the highly successful acquisition in 2020 of the assets of Columbia Gas. 1

1Non-GAAP EPS presented in this Item 11 excludes the one-time transactional costs of $0.09 per share relating to the acquisition in 2020 of the assets of Columbia Gas. Eversource Energy uses this non-GAAP financial measure to more fully compare and explain 2020 results without including the impact of the transactional costs of the Columbia Gas acquisition. Due to the effect of the acquisition costs on net income attributable to common shareholders, management believes that the non-GAAP presentation is a more meaningful representation of Eversource Energy’s financial performance and provides additional information to readers in analyzing historical and future performance of the business. Non-GAAP financial measures should not be considered as alternatives to Eversource Energy’s consolidated net income attributable to common shareholders.

142


DIVIDENDS PAID: The Board of Trustees increased the annual dividend rate by 6.1 percent for 2020 to $2.27 per share, which exceeded the median dividend growth rate of 4.5 percent for the utilities that constitute the Edison Electric Institute Index (EEI Utility Index).

es-20201231_g3.jpg

SHAREHOLDER RETURN: Eversource Energy’s Total Shareholder Return (TSR) in 2020 was 4.5 percent, compared to negative 1.2 percent for the EEI Index, the 5th highest TSR in the EEI Utility Index of 39 companies. Eversource continued to outperform the EEI Utility Index over the last one-, three-, five- and 10-year periods and the Standard & Poor’s 500 over the last three- and 10-year periods. An investment of $1,000 in Eversource’s common shares for the 10-year period beginning January 1, 2011 was worth $3,726 on December 31, 2020. The following chart represents the comparative total shareholder returns for the periods ended December 31, 2020:

es-20201231_g4.jpg

STRATEGIC INITIATIVES AND REGULATORY OUTCOMES: Although Eversource Energy faced challenges caused by the restrictions resulting from the pandemic, Eversource completed the acquisition of the assets of Columbia Gas in seven months; the acquisition was immediately accretive to earnings and is expected to be increasingly so in future years. As part of the acquisition regulatory approval process, Eversource successfully reached a positive 8-year rate settlement agreement for the new entity, Eversource Gas Company of Massachusetts. Eversource achieved constructive outcomes in the PSNH and NSTAR Gas subsidiary rate reviews, completed the sale by the Aquarion Water Company of assets located in Hingham, Massachusetts in satisfaction of a predecessor company agreement, and successfully executed several storm cost recovery proceedings in the three states Eversource serves.

CREDIT RATING: Eversource Energy continues to hold an A- level Corporate Credit Rating at Standard & Poor’s. There is no other holding company with a higher credit rating in the EEI Utility Index.

143


RELIABILITY PERFORMANCE: Electric System Reliability, measured by months between interruptions, was top decile for the industry in 2020; customer power interruptions were on average 19.2 months apart.

es-20201231_g5.jpg

RESTORATION PERFORMANCE: The average system outage duration was 64.0 minutes, also top decile for the fastest restoration time.

es-20201231_g6.jpg

SAFETY: Eversource’s safety performance was 0.7, measured by days away, restricted or transferred (DART) per 100 workers, which continued to outperform the industry in 2020. In addition to the safety performance as measured by DART, the policies and procedures established at the onset of the pandemic contributed significantly to the successful overall safety performance.

es-20201231_g7.jpg

144


GAS EMERGENCY RESPONSE: On-time response to gas customer emergency calls was 99.6 percent, meeting the industry average.

es-20201231_g8.jpg

CUSTOMERS: Eversource continued to add to its customer messaging programs, including those relating to COVID-19, realized all-time highs in both digital messaging and estimated time-to-restore communications, led the industry in the early implementation of customer service termination moratoria, and implemented extended customer forgiveness and payment programs. However, Eversource acknowledged that as a result of Tropical Storm Isaias, which caused extensive, catastrophic damage to the CL&P distribution system and many prolonged outages, its customers and government leaders felt that the performance fell short of their expectations.

CLEAN ENERGY LEADERSHIP: Regarding Eversource’s offshore wind projects, Eversource continued to advance the New London State Pier project in Connecticut, giving the partnership access to the leading offshore wind port in the Northeast; reached a comprehensive settlement for the joint Eversource/Ørsted South Fork project with the Town of East Hampton, New York and the Board of Trustees for South Fork relating to the installation of the onshore transmission facilities to be constructed in those two communities; and submitted Construction and Operating Plans with the U.S. Bureau of Ocean Energy Management for the joint Eversource/Ørsted Revolution Wind and Sunrise Wind projects. In June of 2020, Eversource began construction of a first in the nation community battery storage project at the Provincetown, Massachusetts town transfer station. Eversource’s electric vehicle charging infrastructure program met its targets, Eversource led efforts to expand Massachusetts’ utility scale solar program, and the energy efficiency programs, while slowed by the COVID-19 pandemic, continued to perform at a national leading level as rated by the American Council for an Energy Efficient Economy.

2020 Sustainability/ESG

SUSTAINABILITY: Eversource’s social and environmental accomplishments, which once again in 2020 received widespread recognition, are a measure of the strong commitment to corporate responsibility and are reflected in the high ratings from leading sustainability rating firms. In 2020, Eversource was ranked top quartile within a peer group of comparably sized U.S. utilities whose ESG performance is assessed by the two leading sustainability rating firms. Eversource also continued to take steps to implement and ensure progress towards its industry leading goal to be carbon neutral in their operations by 2030.

COMMUNITY: Despite the challenges of the pandemic, Eversource continued to make a significant impact in the communities it serves through its corporate philanthropy programs and extensive employee volunteer programs. Eversource’s employees devoted 26,000 hours in 2020 to volunteerism in the service territory communities, mostly all under constraints imposed by the pandemic. Eversource’s 2020 charitable giving totaled $8.1 million, including a record amount in contributions by employees to the United Way along with major event lead sponsorships for the Eversource Walk for Children’s Hospital of Boston, Eversource Walk and 5K Run for Easterseals New Hampshire, Mass General Cancer Center/Eversource Every Day Amazing Race, Eversource Hartford Marathon, Travelers Championship and Special Olympics in Connecticut and New Hampshire. Most of these events were held virtually, and many Eversource employees assisted in producing the events to help ensure their success. The Eversource Energy Foundation continues to provide direct support to organizations and large regional initiatives within Eversource’s service territories. In addition, Eversource provided accelerated and targeted community support to COVID-19 relief organizations.

DIVERSITY: Eversource continued to support many programs and agencies that address racial and ethnic disparities in our customers’ communities and beyond. Eversource also continues to develop a workforce that fully reflects the diversity of the people and communities Eversource serves. Eversource’s hiring practices emphasize diversity, and encourage employees to embrace different people, perspectives and experiences in our workplace and within our communities – regardless of their race, color, religion, national origin, ancestry, sex, gender identity, age, disability, marital status, sexual orientation, active military or veteran status. Eversource continued its successful drive to increase workforce diversity; in 2020, 47.6 percent of new hires and promotions into leadership roles were women or people of color. In addition, in response to the social unrest last year, Eversource conducted listening sessions with our business resource groups and established a racial equity task force. Eversource also started a highly attended employee town hall series focused on taking action to advance racial equality and to disrupt racism. In addition, Eversource launched a webinar series on employee resilience and self-care, and created a robust self-service, online communication and learning hub on racial and social justice.

EMPLOYEES/HUMAN CAPITAL MANAGEMENT: Eversource recognizes that its employees are its most valuable asset. Eversource has developed strategic workplans as part of the annual business and workforce planning process to address immediate and long-range needs to ensure that Eversource acquires, develops and retains excellent talent. Virtual learning and development opportunities were provided to employees, including on-boarding sessions with specific focus on engaging new Eversource Gas Company of Massachusetts employees. No employees, whether from the acquired company Columbia Gas or otherwise, were subject to lay-offs as a result of the pandemic. Interactive engagement and support tools were offered to promote remote worker effectiveness supporting the workforce with business, leadership and technical knowledge. Employee development programs were aligned to the strategic workforce plan to support succession within all levels of the organization. Programs like the Growth Opportunities for Leadership Development and the engineering associate cohort programs promoted educational and professional development opportunities for recent college graduates. Tuition assistance programs, paid internships, co-ops and other pipeline development programs continued to the greatest extent possible to ensure progress in future workforce technical skills and competencies. Through targeted training, development and educational activities, Eversource offered high performers numerous learning experiences to ensure their growth and development as future leaders. Thought provoking stretch assignments, high impact cross-functional team memberships, senior management interaction and exposure, targeted coaching and feedback, and diverse learning experiences that promote interdependent thinking, embrace alternative perspectives, while building teamwork and collaboration represent examples of key components of Eversource’s key talent program. With a strong focus on Diversity, Equity and Inclusion, discussions, programs and activities were offered to provide education and experiences to further emphasize messages of Racial and Social Justice. Additionally, Eversource leveraged educational partnerships in critical trade and technical areas and has developed proactive sourcing strategies to attract experienced workers in highly technical roles in areas like engineering, electric and gas operations, and energy efficiency. As part of this process, Eversource identified critical roles and developed succession plans to ensure Eversource has talent now and for the future. Eversource also provides employees with fair pay, comprehensive benefits, and a variety of field and classroom training opportunities throughout their careers to support their ongoing success on the job.

AWARDS: Eversource continued to receive numerous local and national awards in 2020 recognizing Eversource as a leader and catalyst in the areas of Sustainability and ESG.

Eversource was again ranked in the top 100 of America’s Most Just Companies by FORBES/JUST Capital. The listing recognizes corporate social responsibility and commitment to local communities and celebrates public companies for their positive impact and leadership on priorities such as ethical leadership, environmental impact, customer treatment, fair pay and benefits, equal opportunity and shareholder return.

For the second year in a row, Newsweek magazine ranked Eversource as the #1 energy company in their 2021 list of the Most Responsible Companies. This listing is based on an analysis of a company’s corporate social responsibility, as well as a public survey.

For the third consecutive year, Eversource was selected to be included in the Bloomberg Gender-Equality Index, which recognizes companies who have shown their commitment to advancing women’s equality in the workplace and transparency in gender reporting.

Eversource was included in 3BL Media’s ranking of the top 100 Best Corporate Citizens of 2020 for leading ESG transparency and performance among 1,000 of the largest U.S. public companies.

Eversource was recognized by the U.S. Department of Labor as a HIRE Vets Medallion Award recipient for its commitment to recruiting, employing, and retaining veterans. We are proud to support veteran careers.

The National Organization on Disability (NOD) honored Eversource as a 2020 Leading Disability Employer.

Achievement of the 2020 performance goals, additional accomplishments and the Compensation Committee’s assessment of Company and executive performance are more fully described in the section below titled “2020 Annual Incentive Program Assessment.” Specific decisions regarding executive compensation based upon the Committee’s assessment of Company and executive performance and market data are also described below.

Pay for Performance Philosophy

The Compensation Committee links the compensation of the executive officers, including the Named Executive Officers, to performance that will ultimately benefit customers, employees, and shareholders. Eversource’s compensation program is intended to attract and retain the best executive talent in the industry, motivate executives to meet or exceed specific stretch financial and operational goals each year, and compensate executives in a manner that aligns compensation directly with performance. Eversource strives to provide executives with base salary, performance-based annual incentive compensation, and performance-based long-term incentive compensation opportunities that are competitive with market practices and that reward excellent performance.

Executive Compensation Governance

What Eversource DOES:
üPay for Performance
üShare ownership and holding guidelines
üBalanced incentive metrics
üDelivery of the majority of incentive compensation opportunity in long-term equity
üBroad financial and personal misconduct clawback policy relating to incentive compensation
üDouble-trigger change in control vesting provisions
üShareholder engagement meetings throughout the year between management and Eversource shareholders that discuss compensation governance
üFor 2021, 75 percent of long-term incentive compensation will be tied to performance
ü100 percent of long-term incentive compensation paid in equity
üIndependent compensation consultant
üAnnual Say-on-Pay vote
üPayout limitations on incentive awards
üLimited executive and Trustee trading window

What Eversource DOESN’T do:
ûTax gross ups in any new or materially amended executive compensation agreements
ûHedging, pledging or similar transactions by executives and Trustees
ûLiberal share recycling
ûDividends on equity awards before vesting
ûDiscounts or repricing of options or stock appreciation rights
ûChange in control agreements (since 2010)

The executive share ownership and holding guidelines noted in this CD&A emphasize the importance of aligning management with shareholders. Under the share ownership guidelines, which require Eversource’s Chief Executive Officer to hold shares equal to six times base salary, Eversource requires executives to hold 100 percent of the shares awarded under the Company’s stock compensation program until the share ownership guidelines have been met.

Eversource’s Incentive Plan includes a clawback provision that requires executives and all other participants to reimburse the Company for incentive compensation received, not only if earnings are subsequently required to be restated as a result of noncompliance with accounting rules caused by fraud or misconduct, but also for a willful material violation of Eversource’s Code of Business Conduct or significant breach of a material covenant in an employment agreement. The Plan also imposes limits on awards and on Trustee compensation and prohibits repricing of awards and liberal share recycling.

Eversource prohibits gross ups in all new or materially amended executive compensation agreements.

Eversource has a “no hedging and no pledging” policy that prohibits the purchase of financial instruments or otherwise entering into any transactions that are designed to have the effect of hedging or offsetting any decrease in the market value of its common shares.

Eversource’s employment agreements and incentive plan require a “double-trigger” change in control to accelerate compensation.

Named Executive Officers

The executive officers of CL&P listed in the Summary Compensation Table and whose compensation is discussed in this CD&A are referred to as the “Named Executive Officers” under SEC regulations. For 2020, CL&P’s Named Executive Officers were:

Overview of Eversource’s Compensation Program

The Role of the Compensation Committee. The Eversource Board of Trustees has delegated to the Compensation Committee overall responsibility for establishing the compensation program for those senior executive officers, whom we refer to in this CD&A as “executives” and whom are deemed to be “officers” under the SEC’s regulations that determine the persons whose compensation is subject to disclosure. In this role, the Committee sets compensation policy and compensation levels, reviews and approves performance goals and evaluates executive performance. Although this CD&A refers principally to compensation for the Named Executive Officers, the same compensation principles and practices apply to all executives. The compensation of Eversource’s Chief Executive Officer is subject to the further review and approval of all of the independent Eversource Trustees.

Elements of Compensation. Total direct compensation consists of three elements: base salary, annual cash incentive awards, and long-term equity-based incentive awards. Indirect compensation is provided through certain retirement, perquisite, severance, and health and welfare benefit programs.

Eversource’s Compensation Objectives. The objectives of Eversource’s compensation program are to attract and retain superior executive talent, motivate executives to achieve annual and long-term performance goals set each year, and provide total compensation opportunities that are competitive with market practices. With respect to incentive compensation, the Committee believes it is important to balance short-term goals, such as producing earnings, with longer-term goals, such as long-term value creation for shareholders, maintaining a strong balance sheet, and being a leader in clean energy and sustainability. The Committee also places great emphasis on operating performance, customer service, safety, sustainability and workforce diversity. Eversource’s compensation program utilizes performance-based incentive compensation to reward individual and corporate performance and to align the interests of executives with Eversource Energy’s customers, employees, and shareholders. The Committee continually increases expectations to motivate executives and employees to achieve continuous improvement in carrying out their responsibilities to customers to deliver energy and water reliably, safely, mindful of the environment and employee well-being, and at a reasonable cost, while providing an above-average total return to Eversource shareholders.

Setting Compensation Levels. To ensure that Eversource achieves its goal of providing market-based total direct compensation levels to attract and retain top quality management, the Committee provides executives with target compensation opportunities approximately equal to median compensation levels for executive officers of companies in the utility industry comparable to Eversource in size. To achieve that goal, the Committee and its independent compensation consultant work together to determine the market values of executive direct and indirect compensation elements by using competitive market compensation data.

The Committee reviews competitive compensation data obtained from utility and general industry surveys and a specific group of peer utility companies. Incumbent compensation levels may be set below the market median for those executives who are new to their roles, while long-tenured, high performing executives may be compensated above median. The review by Pay Governance performed in December 2020 indicated that Eversource’s aggregate executive compensation levels continue to be aligned with median market rates.

Role of the Compensation Consultant. The Committee has retained Pay Governance as its independent compensation consultant. Pay Governance reports directly to the Committee and does not provide any other services to Eversource. With the consent of the Committee, Pay Governance works cooperatively with Eversource’s management to develop analyses and proposals for presentation to the Committee. The Committee generally relies on Pay Governance for peer group market data and information as to market practices and trends to assess the competitiveness of the compensation Eversource pays to executives and to review the Committee’s proposed compensation decisions.

Pay Governance Independence. In February 2021, the Committee assessed the independence of Pay Governance pursuant to SEC and NYSE rules, and concluded that it is independent and that no conflict of interest exists that would prevent Pay Governance from independently advising the Committee. In making this assessment, the Committee considered the independence factors enumerated in Rule 10C-1(b) under the Securities Exchange Act of 1934, as well as the written representations of Pay Governance that Pay Governance does not provide any other services to Eversource, the level of fees received from Eversource as a percentage of Pay Governance’s total revenues, the policies and procedures employed by Pay Governance to prevent conflicts of interest, and whether the individual Pay Governance advisers with whom the Committee consulted own any Eversource Energy common shares or have any business or personal relationships with members of the Committee or the Eversource executives.

Role of Management. The role of Eversource’s management, and specifically the roles of Eversource’s Chief Executive Officer and the Executive Vice President of Human Resources and Information Technology, are to provide current compensation information to the compensation consultant and analyses and recommendations on executive compensation to the Committee based on the market value of the position, individual performance, experience and internal pay equity. Eversource’s Chief Executive Officer also provides recommendations on the compensation for the other Eversource Named Executive Officers. None of the executives makes recommendations that affect their individual compensation.

MARKET ANALYSIS

The Compensation Committee seeks to provide executives with target compensation opportunities using a range that is approximately equal to the median compensation levels for executive officers of utility companies comparable to Eversource. Set forth below is a description of the sources of the compensation data used by the Committee when reviewing 2020 compensation:

Competitive Compensation Survey Data. The Committee reviews compensation information obtained from surveys of diverse groups of utility and general industry companies that represent Eversource’s market for executive officer talent. Utility industry data serve as the primary reference point for benchmarking officer compensation and are based on a defined peer set, as discussed below, while general industry data are derived from compensation consultant surveys and serve as a secondary reference point. General industry data are used for staff positions and are size adjusted to ensure a close correlation between the market data and the Company’s scope of operations.
148


The Committee references this information, which it obtains from Pay Governance, to evaluate and determine base salaries and incentive opportunities.

Peer Group Data. In support of executive pay decisions, the Committee consulted with Pay Governance, which provided the Committee with a competitive assessment analysis of Eversource’s executive compensation levels as compared to the 18 peer group companies listed in the table below. This peer group, which the Committee reviews annually, was chosen because these companies are similar to Eversource Energy in terms of size, business model and long-term strategies.

Alliant Energy CorporationDominion Energy, Inc.Pinnacle West Capital Corporation
Ameren CorporationDTE Energy CompanyPPL Corporation
American Electric Power Co., Inc.Edison InternationalPublic Service Enterprise Group, Inc.
CenterPoint Energy, Inc.Entergy CorporationSempra Energy
CMS Energy Corp.FirstEnergy Corp.WEC Energy Group, Inc.
Consolidated Edison, Inc.NiSource Inc.Xcel Energy Inc.

The Committee adjusts the target percentages of annual and long-term incentives based on the survey data and recommendations from the Chief Executive Officer, after discussion with the compensation consultant, to ensure that they are approximately equal to competitive median levels.

The Committee periodically reviews the general market for supplemental benefits and perquisites using utility and general industry survey data, including data obtained from companies in the peer group.

MIX OF COMPENSATION ELEMENTS

Eversource targets the mix of compensation for its Chief Executive Officer and its other Named Executive Officers so that the percentages of each compensation element are approximately equal to the competitive median market mix. The mix is heavily weighted toward incentive compensation, and incentive compensation is heavily weighted toward long-term compensation. Since the most senior positions have the greatest responsibility for implementing Eversource’s long-term business plans and strategies, a greater proportion of total compensation is based on performance with a long-term focus.

The Committee determines the compensation for each executive based on the relative authority, duties and responsibilities of the executive. Eversource’s Chief Executive Officer’s responsibilities for the strategic direction and daily operations and management of Eversource are greater than the duties and responsibilities of the other executives. As a result, Eversource’s Chief Executive Officer’s compensation is higher than the compensation of those other executives. Assisted by the compensation consultant, the Committee regularly reviews market compensation data for executive officer positions similar to those held by Eversource’s executives, including its Chief Executive Officer.

The following table sets forth the contribution to 2020 Total Direct Compensation (TDC) of each element of compensation at target, reflected as a percentage of TDC, for the Named Executive Officers. The percentages shown in this table are at target and therefore do not correspond to the amounts appearing in the Summary Compensation Table.

RISK ANALYSIS OF EXECUTIVE COMPENSATION PROGRAM

The overall compensation program includes a mix of compensation elements ranging from a fixed base salary that is not at risk to annual and long-term incentive compensation programs intended to motivate executives and other eligible employees to achieve individual and corporate performance goals that reflect an appropriate level of risk. The fundamental objective of the compensation program is to foster the continued growth and success of Eversource’s business. The design and implementation of the overall compensation program provide the Committee with opportunities throughout the year to assess risks within the compensation program that may have a material effect on Eversource and its shareholders.

The Compensation Committee assesses the risks associated with the executive compensation program on an ongoing basis by reviewing the various elements of incentive compensation. The annual incentive program is designed to ensure an appropriate balance between individual and corporate goals, which were deemed appropriate and supportive of Eversource’s annual business plan. Similarly, the long-term incentive program is designed to ensure that the performance metrics are properly weighted and supportive of Eversource’s strategy. The Committee reviewed the overall compensation program in the context of risks identified in the annual operating plan. The annual and long-term incentive programs were designed to include mechanisms to mitigate risk. These mechanisms include realistic goal setting and discretion with respect to actual payments, in addition to:

A mix of annual and long-term performance awards to provide an appropriate balance of short- and long-term risk and reward horizon;

A variety of performance metrics, including financial, operational, customer service, ESG, diversity and safety goals and other strategic initiatives for annual performance awards to avoid excessive focus on a single measure of performance;

Metrics in Eversource’s long-term incentive compensation program that use earnings per share growth and relative total shareholder return, which are both robust measures of shareholder value and which reduce the risk that employees might be encouraged to pursue other objectives that increase risk or reduce financial performance;

The provisions of Eversource’s annual and long-term incentive programs, which cap awards at 200 percent of target;

Eversource’s expansive clawback provisions on incentive compensation, including clawback for material violations of the Eversource Code of Business Conduct; and

Stock ownership requirements for all executives, including Eversource’s NEOs, and prohibitions on hedging, pledging and other derivative transactions related to Eversource common shares.

Based on these factors, the Compensation Committee and the Board of Trustees believe the overall compensation program risks are mitigated to reduce overall compensation risk.

Results of Eversource's 2020 Say-on-Pay Vote. Eversource provides its shareholders with the required opportunity to cast the annual advisory vote on executive compensation (a Say-on-Pay proposal). At Eversource’s Annual Meeting of Shareholders held on May 6, 2020, 89 percent of the votes cast on the Say-on-Pay proposal were voted to approve the 2019 compensation of the Named Executive Officers, as described in Eversource’s 2020 proxy statement. Say-on-Pay results of the Company, along with utility and general industry peers, are reviewed by the Committee annually to help assess whether Eversource shareholders continue to deem its executives’ compensation to be appropriate. The Committee has and will continue to consider the outcome of Eversource’s s Say-on-Pay votes when making future compensation decisions for the Named Executive Officers.

ELEMENTS OF 2020 COMPENSATION

Base Salary

Base salary is designed to attract and retain key executives by providing an element of total compensation at levels competitive with those of other executives employed by companies of similar size and complexity in the utility and general industries. In establishing base salary, the Compensation Committee relies on compensation data obtained from independent third-party surveys of companies and from an industry peer group to ensure that the compensation opportunities Eversource offers are capable of attracting and retaining executives with the experience and talent required to achieve its strategic objectives. Adjustments to base salaries are generally made on an annual basis except in instances of promotions.

When setting or adjusting base salaries, the Committee considers annual executive performance appraisals; market pay movement across industries (determined through market analysis); targeted market pay positioning for each executive; individual experience; strategic importance of a position; recommendations of the Chief Executive Officer; and internal pay equity.

Due to the hardships experienced by Eversource’s customers and communities as a result of COVID-19 and the extended outages that took place in 2020 in Connecticut following Storm Isaias, and in spite of excellent performance by the executives in 2020, the Compensation Committee determined that it would freeze base salaries for Eversource’s senior executive officers, including its Named Executive Officers, at 2020 levels, rather than provide market based base salary increases.

Incentive Compensation

Annual incentive and long-term incentive compensation are provided under Eversource’s Incentive Plan, which was approved by its shareholders in 2018. The annual incentive program provides cash compensation intended to reward performance under Eversource’s annual operating plan. The long-term stock-based incentive program is designed to reward demonstrated performance and leadership, motivate future performance, align the interests of the executives with those of shareholders, and retain executives during the term of grants. The annual and long-term programs are designed to strike a balance between Eversource’s short- and long-term objectives so that the programs work in tandem.

In addition to the specific performance goals, the Committee assesses other factors, as well as the executives’ roles and individual performance and then makes annual incentive program awards at the levels and amounts disclosed in this CD&A.

2020 ANNUAL INCENTIVE PROGRAM ASSESSMENT

In early February of 2020, the Committee established the terms of the 2020 Annual Incentive Program. As part of the overall program, and after consulting with Pay Governance, the Committee set target award levels for each of Eversource’s Named Executive Officers that ranged from 70 percent to 125 percent of base salary.

At the February 2020 meeting, the Committee determined that for 2020 it would continue to base 70 percent of the annual incentive performance goals on Eversource’s overall financial performance and 30 percent of the annual performance goals on Eversource’s overall operational performance. The Committee also determined the specific goals that would be used to assess performance, with potential ratings on each goal ranging from zero percent to 200 percent of target. The Committee assigned weightings to each of the goals. For the financial component, the following goals were used: earnings per share, weighted at 60 percent, dividend growth, weighted at 10 percent, and advancement of strategic growth initiatives and regulatory outcomes, weighted at 30 percent. For the operational component, the Committee used the following goals: combined service reliability and restoration goals, weighted at 50 percent, and combined safety ratings, gas service response, diversity promotions and hires of leadership employee positions, and sustainability, customer and clean energy initiatives, weighted at 50 percent.

In establishing the individual annual performance goals, the Committee sets stretch goals for both the Financial and Operational components. Many of the goals use performance ranges, as opposed to threshold or target metrics, whereby the lower end of the performance range does not represent average or less compared to industry peers, or other similar performance benchmarks, but requires performance that exceeds industry standards, peer performance and other benchmarks in order to be met, while achievement at the higher end of the range represents top-of-industry performance. Achieving performance of these stretch goals within the particular range will therefore justify an assessment beyond target.

2020 Performance Goals

es-20201231_g10.jpg

At the December 2020 meeting of the Committee, Eversource’s management provided an initial review of its 2020 performance, followed in February 2021 by a full assessment of the performance goals, the additional accomplishments noted below under the caption “Additional Factors” and the overall performance of Eversource and its executives. In addition to these meetings, the Committee and the Eversource Board were provided updates during 2020 on corporate performance. At the February 8, 2021 meeting, the Committee determined, based on its assessment of the financial and operational performance goals, to set the level of achievement of combined financial and operational performance goals results at 161 percent, reflecting the strong performance of Eversource and its executive team in executing Eversource’s Operating Plan and adapting quickly to the COVID-19 pandemic to keep its customers and employees safe and to maintain effective operations. In arriving at this determination, the Committee determined that the weighted financial performance goals result was 116 percent and the weighted operational performance goals result was 45 percent. In making the awards, the Committee made its determinations on the results without factoring the pandemic into its deliberations and did not take into account the additional complexities involved in executing the Operating Plan and accomplishing the goals. Eversource’s Chief Executive Officer recommended to the Committee awards for its executives (other than himself) based on his assessment of each of the executive’s individual performance towards achievement of the performance goals and the additional accomplishments of Eversource, together with each of the executive’s contributions to the overall performance of Eversource. The actual awards determined by the Committee were also based on the same criteria.

Financial Performance Goals Assessment

FINANCIAL PERFORMANCE: Eversource’s non-GAAP earnings per share in 2020, which excludes the Columbia Gas asset acquisition transactional costs, increased by 5.5 percent when compared to non-GAAP earnings per share in 2019, and met the established goal of $3.64. Eversource was able to achieve this goal through effective management of the 2020 Operating Plan on a day-by-day basis and by overcoming several challenges to plan achievement, including higher than plan O&M expenses caused primarily by the significant number and severity of storm events and the financial and operational impacts of the COVID-19 pandemic.

In determining that it was appropriate to assess the earnings per share goal based on recurring, non-GAAP earnings, the Committee considered the fact that the one-time transactional costs of the complex Columbia Gas asset acquisition, which were the only costs excluded in the calculation of non-GAAP earnings, were a significant strategic opportunity for Eversource, completed in an accelerated timeframe with constructive regulatory outcomes. The Committee determined the earnings per share goal to have attained a 150 percent performance result.

152


DIVIDEND GROWTH: Eversource increased its dividend to $2.27 per share, a 6.1 percent increase from the prior year, significantly above the utility industry’s median dividend growth of 4.5 percent for the EEI Utility Index. The Committee determined this goal to have attained a 160 percent performance result.

es-20201231_g3.jpg

STRATEGIC INITIATIVES AND REGULATORY OUTCOMES: Although Eversource faced challenges caused by the restrictions resulting from the pandemic, it successfully completed the acquisition of the assets of Columbia Gas in seven months; the acquisition was immediately accretive to earnings and is expected to be increasingly so in future years. As part of the acquisition regulatory approval process, Eversource successfully reached a constructive 8-year rate settlement agreement for the new entity, Eversource Gas Company of Massachusetts. Eversource achieved constructive outcomes in the PSNH and NSTAR Gas subsidiary rate reviews, completed the sale by the Aquarion Water Company of assets located in Hingham, Massachusetts in satisfaction of a predecessor company agreement, and successfully executed several storm cost recovery proceedings in the three states Eversource serves. The Committee determined this goal to have attained a 200 percent performance result.

Operational Performance Goals Assessment

RELIABILITY PERFORMANCE: Electric System Reliability, measured by months between interruptions, was top decile in the industry in 2020; customer power interruptions were on average 19.2 months apart. The Committee determined this goal to have attained a 175 percent performance result.

es-20201231_g5.jpg

153


RESTORATION PERFORMANCE: The average system outage duration was 64.0 minutes, which was in the top decile of the industry for the fastest restoration time. The Committee determined this goal to have attained a 175 percent performance result.

es-20201231_g6.jpg

SAFETY: Eversource’s safety performance was 0.7, measured by days away, restricted or transferred (DART) per 100 workers, which continued to outperform the industry in 2020. In addition to the safety performance as measured by DART, the policies and procedures Eversource established at the onset of the pandemic were and continue to be a significant and successful part of our overall safety performance. The Committee determined this goal to have attained a 150 percent performance result.

es-20201231_g7.jpg

GAS EMERGENCY RESPONSE: On-time response to gas customer emergency calls was 99.6 percent, meeting industry standards. The Committee determined this goal to have attained a 100 percent performance result.

es-20201231_g8.jpg

154


DIVERSITY: Eversource continued to support many programs and agencies that address racial and ethnic disparities in its customers’ communities and beyond. Eversource also continues to develop a workforce that fully reflects the diversity of the people and communities Eversource serves. Eversource’s hiring practices emphasize diversity, and encourage employees to embrace different people, perspectives and experiences in its workplace and within its communities – regardless of their race, color, religion, national origin, ancestry, sex, gender identity, age, disability, marital status, sexual orientation, active military or veteran status. Eversource continued its successful drive to increase workforce diversity; in 2020, 47.6 percent of new hires and promotions into leadership roles were women or people of color. In addition, in response to the social unrest last year, Eversource conducted listening sessions with its business resource groups and established a racial equity task force. Eversource also started a highly attended employee town hall series focused on taking action to advance racial equality and to disrupt racism. In addition, Eversource launched a webinar series on employee resilience and self-care, and created a robust self-service, online communication and learning hub on racial and social justice. The Committee determined this goal to have attained a 200 percent performance result.

SUSTAINABILITY: Eversource’s goal in 2020 was to be in the 75th percentile performance of a peer group of comparably sized U.S. utilities whose ESG performance is assessed by two leading sustainability rating firms. Eversource’s performance was determined to be at the 85th percentile of the peer group. The Committee determined this goal to have attained a 150 percent performance result.

CUSTOMERS: Eversource continued to add to its customer messaging programs, including those relating to COVID-19, realized all-time highs in both digital messaging and estimated time to restore communications, led the industry in the early implementation of customer service termination moratoria, and implemented extended customer forgiveness and extended payment programs. However, Eversource acknowledged that as a result of Tropical Storm Isaias, which caused extensive, catastrophic damage to CL&P’s distribution system and many prolonged outages, its customers’ and government leaders’ perception was that its performance fell short of their expectations. In recognition of this sentiment, the Committee did not attribute any performance percentage value to the customer goals in its overall assessment to the goals, such that the goal was assessed at zero percent.

CLEAN ENERGY LEADERSHIP: Regarding Eversource’s offshore wind projects, Eversource continued to advance the New London State Pier project in Connecticut, giving the Eversource/Ørsted partnership access to the leading offshore wind port in the Northeast; reached a comprehensive settlement for the joint Eversource/Ørsted South Fork project with the Town of East Hampton, New York and the Board of Trustees for South Fork relating to the installation of the onshore transmission facilities to be constructed in those two communities; and submitted Construction and Operating Plans with the U.S. Bureau of Ocean Energy Management for the joint Eversource/Ørsted Revolution Wind and Sunrise Wind projects. In June of 2020, Eversource began construction of a first in the nation community battery storage project at the Provincetown, Massachusetts town transfer station. Eversource’s electric vehicle charging infrastructure program met its 2020 targets; Eversource led efforts to expand Massachusetts’ utility scale solar program, and Eversource’s energy efficiency programs, while slowed by the COVID-19 pandemic, continued to perform at national leading level as noted by the American Council for an Energy Efficient Economy. The Committee determined this goal to have attained a 125 percent performance result.

Additional Factors

The following important financial, strategic, operational, environmental and customer-focused results were also considered by the Committee in assessing overall financial and operational performance, but were not given specific weightings or assigned a specific performance assessment score:

Eversource was again ranked in the top 100 of America’s Most Just companies by FORBES/JUST Capital. The listing recognizes corporate social responsibility and commitment to the local communities and celebrates public companies for their positive impact and leadership on priorities such as ethical leadership, environmental impact, customer treatment, fair pay and benefits, equal opportunity and shareholder return.

Again this year, Newsweek magazine ranked Eversource as the #1 energy company in their 2021 list of the Most Responsible Companies. This listing is based on an analysis of a company’s corporate social responsibility, as well as a public survey.

For the third consecutive year, Eversource was selected to be included in the Bloomberg Gender-Equality Index, which recognizes companies who have shown their commitment to advancing women’s equality in the workplace and transparency in gender reporting.

Eversource was included in 3BL Media’s ranking of the top 100 Best Corporate Citizens of 2020 for leading ESG transparency and performance among 1,000 of the largest U.S. public companies.

Eversource was recognized by the U.S. Department of Labor as a HIRE Vets Medallion Award recipient for its commitment to recruiting, employing, and retaining veterans. We are proud to support veteran careers.

The National Organization on Disability (NOD) honored Eversource as a 2020 Leading Disability Employer. Now in its sixth year, the NOD Leading Disability Employer Seal is a recognition of organizations that are leading the way in disability inclusion and tapping into the many benefits of hiring talent who are differently-abled, including high rates of productivity and dedication, and greater employee engagement across the workforce.

Eversource was one of only four energy companies included in Barron’s 2020 Most Sustainable Companies list. Barron’s bases this list on 230 performance indicators that address environmental, social and governance matters.

Eversource was again selected as a “most honored” company by Institutional Investor magazine in its survey of some 1,500 portfolio managers and investment analysts. Eversource was designated as the #2 utility company in each of the eight company categories, including those related to ESG.

Eversource’s 2020 charitable giving totaled $8.1 million, including major event lead sponsorships for the Eversource Walk for Children’s Hospital of Boston, Eversource Walk and 5K Run for Easterseals New Hampshire, Mass General Cancer Center/Eversource Every Day Amazing Race, Eversource Hartford Marathon, Travelers Championship, and Special Olympics in Connecticut and New Hampshire. Most of these events were held “virtually”, and many Eversource employees assisted in carrying out of these events to help ensure their success.

Individual Executives' Performance Factors Considered by the Committee

It is the Committee’s philosophy to provide incentives for Eversource executives to work together as a highly effective, integrated team to achieve or exceed the financial, operational, safety, customer, sustainability, strategic and diversity goals and objectives. The Committee also reviews and assesses individual executive performance. The Committee based the annual incentive payments on team performance and the Committee’s assessment of each of Eversource’s executive’s individual performance in supporting the performance goals, additional achievements, and overall results of Eversource. With respect to Eversource’s Chief Executive Officer, the Committee and Eversource’s independent Trustees assessed his performance. Based on the recommendations of Eversource’s Chief Executive Officer as to executives other than himself, the Committee assessed the performance of the Named Executive Officers and Eversource to be excellent in totality and approved annual incentive program payments for its Named Executive Officers at levels that ranged from 149 percent to 167 percent of target. These payments reflected the individual and team contributions of each of the Named Executive Officers in achieving the goals and the additional accomplishments and the overall performance of the Company.

In determining Mr. Judge’s annual incentive payment of $2,750,000, which was 161 percent of target and which reflects his and Eversource’s excellent 2020 performance, the Eversource Committee and Board considered the totality of Eversource’s success in accomplishing the goals set by the Committee. The Committee also reviewed the additional accomplishments of Eversource and the superior leadership of Mr. Judge, who again led a very high- performing company to another successful year, including Mr. Judge’s continued emphasis on the importance of both protecting the planet and pushing for racial and social justice while ensuring a focus on the safety of Eversource employees and the public from the very beginning of the pandemic, which he continues to do to this day.

Long-Term Incentive Program

General Discussion and Changes for 2021

Eversource’s long-term incentive program is intended to focus on its longer-term strategic goals and to help retain its executives. A new three-year program commences every year. For the three programs described below, each of Eversource’s executive’s target long-term incentive opportunity consisted of 50 percent Performance Shares and 50 percent RSUs. However, for the 2021 – 2023 Program, Eversource has increased the percentage of total long term incentive opportunity that is provided in performance shares to a mix of 75 percent Performance Shares and 25 percent RSUs in response to shareholder comments that it received at shareholder engagement sessions that suggested that the percentage of performance shares should be increased, and to further align its compensation programs with the Committee’s pay for performance philosophy. Performance Shares are designed to reward long-term achievements as measured against pre-established performance measures. RSUs are designed to provide executives with an incentive to increase the value of the Eversource’s common shares in alignment with shareholder interests, while also serving as a retention component for executive talent. Eversource believes these compensation elements create a focus on continued Company and share price growth to further align the interests of Eversource executives with the interests of Eversource shareholders.

Performance Share Grants

General

Performance Shares are designed to reward future financial performance, measured by long-term earnings growth and shareholder returns over a three-year performance period, therefore aligning executive compensation with performance. Performance Shares are granted as a target number of Eversource Energy common shares. The number of Performance Shares is determined by dividing the target grant value in dollars by the average daily closing prices of Eversource common shares on the New York Stock Exchange for the ten business days preceding the grant date and rounding to the nearest whole share. Until the end of the performance period, the value of dividends that would have been paid with respect to the Performance Shares had the Performance Shares been actual common shares will be deemed to be invested in additional Performance Shares, which remain at risk and do not vest until actual performance for the period is determined.

Performance Shares under the 2020 – 2022 and 2019 – 2021 Programs

For the 2020 – 2022 Program, the Committee determined it would measure performance using: (i) average diluted earnings per share growth (EPSG); and (ii) relative total shareholder return (TSR) measured against the performance of companies that comprise the EEI Index. As in previous years, the Committee selected EPSG and TSR as performance measures because the Committee continues to believe that they are generally recognized as the best indicators of overall corporate performance. The Committee considers it a best practice to use a combination of relative and absolute metrics, with absolute EPS growth serving as a key input to shareholder value and relative TSR serving as the output.

The Committee also determined that for the 2020-2022 Program it would increase the degree of EPSG performance required to achieve a target (100 percent) award from that required under previous years’ Programs, and modified the Program by adding additional levels for which no award of shares would be made.

The number of Performance Shares awarded at the end of the three-year period ranges from zero percent to 200 percent of target, depending on EPSG and relative TSR performance as set forth in the performance matrix below. Performance Share grants are based on a percentage of annualized base salary at the time of the grant and are measured in dollars. The target number of shares under the 2020-2022 Program for the Named Executive Officers ranged from 90 percent to 240 percent of base salary. Vesting at 100 percent of target occurs at various combinations of EPSG and TSR performance. In addition, the value of any performance shares that actually vest may increase or decrease over the vesting period based on Eversource’s share price performance. The number of performance shares granted at target were approved as set forth in the table below. The Committee and the independent members of the Eversource Board determined the Performance Share grants for its Chief Executive Officer. Based on input from Eversource’s Chief Executive Officer, the Committee determined the Performance Share grants for each of its other executive officers, including the other Named Executive Officers.

For the 2019 — 2021 Program, the Committee used the same performance measures of EPSG and TSR and used the same criteria used in the 2018 — 2020 Program.

The performance matrices set forth below describe how the Performance Share payout will be determined under the 2020 – 2022 Long-Term Incentive Programs and how the Performance Share payout was determined under the 2018 – 2020 Program and will be determined under the 2019 - 2021 Program. Three-year average EPSG is cross-referenced with the actual three-year TSR percentile to determine actual performance share payout as a percentage of target,

Results of the 2018 – 2020 Performance Share Program

The 2018 – 2020 Program was completed on December 31, 2020. The actual performance level achieved under the Program was a three-year average adjusted EPS growth of 5.4 percent and a three-year total shareholder return at the 92nd percentile, which, when interpolated in accordance with the criteria established by the Committee, resulted in vesting performance share units at 156 percent of target. 2019 and 2020 non-GAAP earnings per share, which excluded the Northern Pass Transmission Project impairment charge in 2019, as disclosed in Eversource’s 2020 proxy statement CD&A, and the Columbia Gas acquisition transaction costs charge in 2020, were the basis for performance level assessment determined by the Committee at its February 2020 and 2021 meetings. Please see “2020 Annual Incentive Program Assessment – FINANCIAL PERFORMANCE,” above. At its February 8, 2021 meeting, the Committee confirmed that the actual results achieved were calculated in accordance with established performance criteria. The number of Performance Shares awarded to Eversource’s Named Executive Officers were approved as set forth in the table below.

Restricted Share Units (RSUs)

General

Each RSU granted under the long-term incentive program entitles the holder to receive one common share at the time of vesting. All RSUs granted under the long-term incentive program vest in equal annual installments over three years. RSU holders are eligible to receive reinvested dividend units on outstanding RSUs held by them to the same extent that dividends are declared and paid on Eversource common shares. Reinvested dividend equivalents are accounted for as additional RSUs that accrue and are distributed with the common shares issued upon vesting of the underlying RSUs. Common shares, including any additional common shares in respect of reinvested dividend equivalents, are not issued for any RSUs that do not vest.

The Committee determined RSU grants for each Eversource executive officer participating in the long-term incentive program. RSU grants are based on a percentage of annualized base salary at the time of the grant. In 2020, the percentage used for each Eversource Named Executive Officer was based on their position in Eversource and ranged from 90 percent to 240 percent of base salary. The Committee reserves the right to increase or decrease the RSU grant from target for each executive officer under special circumstances. The Committee and all other independent members of the Eversource Board determined the RSU grants for its Chief Executive Officer. Based on input from Eversource’s Chief Executive Officer, the Committee determined the RSU grants for each of the other executive officers, including Eversource’s Named Executive Officers.

All RSUs are granted on the date of the Committee meeting at which they are approved. RSU grants are subsequently converted from a percent of salary into common share equivalents by dividing the value of each grant by the average closing price for Eversource common shares over the ten trading days prior to the date of the grant. RSU grants at 100 percent of target were approved as set forth in the table below.

Clawbacks

If Eversource’s earnings were to be restated as a result of noncompliance with accounting rules caused by fraud or misconduct, or if a plan participant engages in a willful material violation of the Eversource Code of Business Conduct or material corporate policy, or the breach of a material covenant in an employment agreement, as determined by the Eversource Board of Trustees, the participant will be required by Eversource’s 2018 Incentive Plan to reimburse Eversource for incentive compensation awards received by them for that year.

No Hedging and No Pledging Policy

Eversource has a long-standing policy prohibiting the purchase of any financial instruments or otherwise entering into transactions designed to have the effect of hedging or offsetting any decrease in the value of its common shares or other equity securities of Eversource or its subsidiaries by its Trustees and executives, including exchange-traded options to purchase or sell securities of Eversource (so-called “puts” and “calls”) or
160


financial instruments that are designed to hedge or offset any decrease in the market value of securities of Eversource (including, but not limited to, prepaid variable forward contracts, equity swaps, collars and exchange funds). This policy also prohibits short sales, the holding of any Eversource common shares in a margin account, borrowing shares, selling future securities that establish a position that increases in value as the value of the Eversource’s stock decreases, or pledging Eversource’s common shares. The policy applies to Trustees and executives but not to non-executives and does not apply to broad-based index funds or similar transactions.

Share Ownership Guidelines and Retention Requirements

The Committee has approved share ownership guidelines to further emphasize the importance of share ownership by Eversource officers. As indicated in the table below, the guidelines call for Eversource’s Chief Executive Officer to own common shares equal to six times base salary, executive vice presidents to own a number of common shares equal to three times base salary, senior vice presidents to own common shares equal to two times base salary, and all other officers to own a number of common shares equal to one to one and one half times base salary. Officers and Eversource Trustees may only transact in Eversource Energy common shares during approved trading windows and are subject to continuing compliance with these share ownership guidelines.

Executive OfficerBase Salary Multiple
Chief Executive Officer6
Executive Vice Presidents3
Operating Company Presidents / Senior Vice Presidents2
Vice Presidents1 – 1.5

Eversource requires that its officers attain these ownership levels within five years after promotion. All of Eversource’s officers, including Eversource’s Named Executive Officers, have either satisfied these share ownership guidelines or are expected to satisfy them within the applicable timeframe. Common shares, whether held of record, in street name, or in individual 401(k) accounts, and RSUs satisfy the ownership requirements. Unvested performance shares do not count toward satisfying the ownership guidelines. In addition to these share ownership guidelines noted above, all Eversource officers must hold the net shares awarded under Eversource’s incentive compensation plan until the share ownership guidelines have been met.

Other Benefits

Retirement Benefits

Eversource provides a qualified defined benefit pension program for certain officers, which is a final average pay program subject to tax code limits. Because of such limits, Eversource also maintains a supplemental non-qualified pension program. Benefits are based on base salary and certain incentive payments, which is consistent with the goal of providing a retirement benefit that replaces a percentage of pre-retirement income. The supplemental program compensates for benefits barred by tax code limits, and generally provides (together with the qualified pension program) benefits equal to approximately 60 percent of pre-retirement compensation (subject to certain reductions) for Messrs. Judge, Lembo, Schweiger and Nolan, and approximately 50 percent of such compensation for Mr. Butler. The supplemental program was discontinued in 2012 for newly elected officers.

For certain participants, the benefits payable under the Supplemental Non-Qualified Pension Program differ from those described above. The program benefit payable to Mr. Schweiger is fully vested and is further reduced by benefits he is entitled to receive under previous employers’ retirement plans.

Also see the narrative accompanying the “Pension Benefits” table and accompanying notes for more detail on the above program.

401(k) Benefits

Eversource offers a qualified 401(k) program for all employees, including executives, subject to tax code limits. After applying these limits, the program provides a match of 50 percent of the first eight percent of eligible base salary, up to a maximum of $11,400 per year for Messrs. Judge, Lembo, Schweiger and Nolan. For Mr. Butler, Eversource provides a match of 100 percent of the first three percent of eligible base salary, up to a maximum of $8,550 per year.

Deferred Compensation

Eversource offers a non-qualified deferred compensation program for its executives. In 2020, the program allowed deferral of up to 100 percent of base salary, annual incentives and long-term incentive awards. The program allows participants to select investment measures for deferrals based on an array of deemed investment options (including certain mutual funds and publicly traded securities).

See the Non-Qualified Deferred Compensation Table and accompanying notes for additional details on the above program.

Perquisites

Eversource provides executives with limited financial planning benefits, vehicle leasing and access to tickets to sporting events. The current level of perquisites does not factor into decisions on total compensation.

161


Contractual Agreements

Eversource maintains contractual agreements with all of its Named Executive Officers that provide for potential compensation in the event of certain terminations, including termination following a Change in Control. Eversource believes these agreements are necessary to attract and retain high quality executives and to ensure executive focus on Eversource business during the period leading up to a potential Change in Control. The agreements are “double-trigger” agreements that provide executives with compensation in the event of a Change in Control followed by termination of employment due to one or more of the events set forth in the agreements, while still providing an incentive to remain employed with the Company for the transition period that follows.

Under the agreements, certain compensation is generally payable if, during the applicable change in control period, the executive is involuntarily terminated (other than for cause) or terminates employment for “good reason.” These agreements are described more fully in the Tables following this CD&A under “Payments Upon Termination.” The Company has not entered into a Change in Control or employment agreement with any executive since 2010.

Tax and Accounting Considerations

Section 162(m) of the Internal Revenue Code precludes a public company from taking an income tax deduction in any one year for compensation in excess of $1 million payable to its named executive officers who are employed on the last day of the fiscal year, unless certain specific performance goals are satisfied. Until January 1, 2018, there was an exception to the $1 million limitation for performance-based compensation meeting certain requirements. This exception was repealed, effective for taxable years beginning after December 31, 2017 and the limitation on deductibility generally was expanded to include all Named Executive Officers. As a result, compensation paid to Named Executive Officers in excess of $1 million per officer will not be deductible unless it qualifies for transition relief applicable to certain arrangements in place as of and not modified after November 2, 2017.

The Committee believes that the availability of a tax deduction for forms of compensation should be one of many factors taken into consideration of providing market-based compensation to attract and retain highly qualified executives. The Committee believes it is in Eversource’s best interests to retain discretion to make compensation awards, whether or not deductible.

Eversource has adopted the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 718, Compensation-Stock Compensation. In general, Eversource and the Committee do not consider accounting considerations in structuring compensation arrangements.

Equity Grant Practices

Equity awards noted in the compensation tables are made annually at the February meeting of the Compensation Committee (subject to further approval by all of the independent members of the Eversource Board of Trustees of its Chief Executive Officer’s award) when the Committee also determines base salary, annual incentive opportunities, long-term incentive compensation grants, and annual and long-term performance plan awards. The date of this meeting is chosen at least a year in advance, and therefore awards are not coordinated with the release of material non-public information.

(1)    Reflects the aggregate grant date fair value of restricted share units (RSUs) and performance shares granted in each fiscal year, calculated in accordance with FASB ASC Topic 718.

RSUs were granted to each Named Executive Officer in 2020 as long-term compensation, which vest in equal annual installments over three years. Each of the Named Executive Officers was also granted performance shares as long-term incentive compensation. These performance shares will vest based on the extent to which the performance conditions described in the CD&A are achieved as of December 31, 2022. The grant date fair values for the performance shares, assuming achievement of the highest level of both performance conditions, are as follows: Mr. Judge: $5,038,577; Mr. Lembo: $1,213,649; Mr. Schweiger: $1,297,979; Mr. Nolan: $1,070,429; and Mr. Butler: $924,116.

Holders of RSUs and performance shares are eligible to receive dividend equivalent units on outstanding awards to the same extent that dividends are declared and paid on Eversource common shares. Dividend equivalent units are accounted for as additional common shares that accrue and are distributed simultaneously with those common shares that are issued upon vesting of the underlying RSUs and performance shares. No dividends are paid unless and until the underlying shares vest.

(2)    Includes payments to the Named Executive Officers under the 2020 Annual Incentive Program: Mr. Judge: $2,750,000; Mr. Lembo: $950,000; Mr. Schweiger: $950,000; Mr. Nolan: $850,000; and Mr. Butler: $700,000.

(3)    Includes the actuarial increase in the present value from December 31, 2019 to December 31, 2020 of the Named Executive Officers’ accumulated benefits under all of Eversource’s defined benefit pension programs and agreements, determined using interest rate and mortality rate assumptions consistent with those appearing in the footnotes to this Annual Report on Form 10-K. The Named Executive Officer may not be fully vested in such amounts. More information on this topic is set forth in the Pension Benefits table. There were no above-market earnings in deferred compensation value during 2020, as the terms of the Deferred Compensation Plan provide for market-based investments, including Eversource common shares.

(4)    Includes matching contributions allocated by us to the accounts of Named Executive Officers under the 401k Plan as follows: $11,400 for each of Messrs. Judge, Lembo, Schweiger and Nolan, and $8,550 for Mr. Butler. For Mr. Judge, the value shown includes financial planning services valued at $5,000 and $12,434 representing the value in 2020 of a company-owned vehicle provided to Mr. Judge. For Mr. Lembo, the value shown includes financial planning services valued at $5,000 and $5,585 representing the value in 2020 of a company-owned vehicle provided to Mr. Lembo. None of the other Named Executive Officers received perquisites valued in the aggregate in excess of $10,000.

(5)    The amounts in the Adjusted SEC Total column reflect an adjustment to the total compensation reported in the column marked SEC Total. The Adjusted SEC Total subtracts the actuarial change in pension value disclosed in the column titled “Change in Pension Value and Non-Qualified Deferred Earnings” as further described in footnote 3 above in order to reflect compensation earned during the year by the executive without consideration of pension benefit impacts. The amounts in this column differ substantially from, and are not a substitute for, the amounts noted in the SEC Total.

(1)    Awards and market values of awards appearing in the table and the accompanying notes have been rounded to whole units.

(2)A total of 83,765 unvested RSUs vested on February 5, 2021 (Mr. Judge: 46,351; Mr. Lembo: 10,400; Mr. Schweiger: 10,644; Mr. Nolan: 8,106; and Mr. Butler: 8,243). A total of 52,269 unvested RSUs will vest on February 7, 2022 (Mr. Judge: 28,560; Mr. Lembo: 6,514, Mr. Schweiger: 6,719; Mr. Nolan: 5,292 and Mr. Butler: 5,184). A total of 23,266 unvested RSUs will vest on February 6, 2023 (Mr. Judge: 12,281; Mr. Lembo: 2,959; Mr. Schweiger: 3,164; Mr. Nolan: 2,609 and Mr. Butler: 2,253).

(3)    The market value of RSUs is determined by multiplying the number of RSUs by $86.51, the closing price per common share on December 31, 2020, the last trading day of the year.

(4)    Reflects the target payout level for performance shares granted under the 2018 – 2020 Program, the 2019 – 2021 Program and the 2020 – 2022 Program.

The performance period for the 2018 – 2020 Program ended on December 31, 2020. Awards under that program are set forth in the CD&A under the “Results of the 2018 – 2020 Performance Share Program.”

The performance share awards for 2019 – 2021 Program and the 2020 – 2022 Program will be based on actual performance results as a percentage of target, subject to reduction for applicable payroll withholding taxes. As described more fully under “Performance Shares” in the CD&A and footnote (1) to the Grants of Plan-Based Awards table, performance shares will vest following a three-year performance period based on the extent to which the two performance conditions are achieved. Under the 2019 – 2021 Program, a total of 87,012 performance shares (including accrued dividend equivalents) will vest based on the extent to which the two performance conditions described in the CD&A are achieved as of December 31, 2021. Assuming achievement of these conditions at a target level of performance, the amount of the awards would be as follows: Mr. Judge: 48,834; Mr. Lembo: 10,668; Mr. Schweiger: 10,668; Mr. Nolan: 8,049; and Mr. Butler: 8,793. Under the 2020 – 2022 Program, a total of 69,791 performance shares (including accrued dividend equivalents) will vest based on the extent to which the two performance conditions described in the CD&A are achieved as of December 31, 2022. Assuming achievement of these conditions at a target level of performance, the amount of the awards would be as follows: Mr. Judge: 36,842; Mr. Lembo: 8,874; Mr. Schweiger: 9,491; Mr. Nolan: 7,827; and Mr. Butler: 6,757. No dividends are paid unless and until the underlying shares vest.

(5)    The market value is determined by multiplying the number of performance shares in the adjacent column by $86.51, the closing price of Eversource Energy common shares on December 31, 2020, the last trading day of the year.

In all cases, the distribution of common shares are reduced by that number of shares valued in an amount sufficient to satisfy payroll tax withholding obligations.

(2)    Values realized on vesting of RSUs granted under the 2017 – 2019, 2018 – 2020 and 2019 – 2021 Programs were based on $93.66 per share, the closing price of Eversource Energy common shares on February 14, 2020. Values realized on vesting of performance shares granted under the 2017 – 2019 Program were based on $95.65 per share, the closing price of Eversource common shares on February 20, 2020.

PENSION BENEFITS IN 2020

The Pension Benefits Table shows the estimated present value of accumulated retirement benefits payable to each Named Executive Officer upon retirement based on the assumptions described below. The table distinguishes between benefits available under the qualified pension plan program (QP), the pension equity plan program (PEP), the supplemental pension program (SERP), and the supplemental pension (Excess). See the narrative above in the CD&A under the captions “Other Benefits – Retirement Benefits” and “Contractual Agreements” for more detail on benefits under these plans and our agreements.

The values shown in the Pension Benefits Table for Messrs. Judge, Lembo, Schweiger and Nolan were calculated as of December 31, 2020 based on benefit payments in the form of a lump sum. For Mr. Butler, we assumed a payment of benefits in the form of a contingent annuitant option. Such earned pension program benefit value could otherwise have changed because of the reduction in mortality factors and potentially rising interest rates.

The values shown in this Table for the Named Executive Officers were based on benefit payments on the actual ages or the earliest possible ages for retirement with unreduced benefits for the Named Executive Officers: Mr. Judge: age 60, Mr. Lembo, age: 62, Mr. Schweiger: age 55, Mr. Nolan: age 62 and Mr. Butler: age 62.

In addition, we determined benefits under the qualified pension program using tax code limits in effect on December 31, 2020. For Messrs. Judge, Lembo, Schweiger and Nolan, the values shown reflect actual 2020 salary and annual incentives earned in 2019 but paid in 2020 (per applicable supplemental program rules). For Mr. Butler, the values shown reflect actual 2020 salary and annual incentives earned in 2020 but paid in 2021 (per applicable supplemental program rules).

We determined the present value of benefits at retirement age using the discount rate within a range of 2.48 percent to 2.54 percent under ACS 715-30 pension accounting for the 2020 fiscal year end measurement as of December 31, 2020. This present value assumes no pre-retirement mortality, turnover or disability. However, for the postretirement period beginning at retirement age, we used the 2020 IRS lump sum mortality table for Messrs. Judge, Lembo, Schweiger and Nolan. We used the RP2014 Employee Table Projected Generationally with Scale MP2020 for Mr. Butler. This new mortality table (as published by the Society of Actuaries in 2014) and projection scale were used by the Eversource Pension Plan for year-end 2020 financial disclosure. Additional assumptions appear in the footnotes to this Annual Report on Form 10-K.

The aggregate balances reflect a significant level of earnings on previously earned and deferred compensation.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

The discussion and tables below show compensation payable to each Named Executive Officer who is still an employee of Eversource, in the event of: (i) voluntary termination; (ii) involuntary not-for-cause termination; (iii) termination in the event of death or disability; and (iv) termination following a change in control. No amounts are payable in the event of a termination for cause. The amounts shown assume that each termination was effective as of December 31, 2020, the last business day of the fiscal year.

Generally, a “change in control” means a change in ownership or control effected through (i) the acquisition of 30 percent or more of the combined voting power of common shares or other voting securities (20 percent for Mr. Butler, excluding certain defined transactions); (ii) the acquisition of more than 50 percent of Eversource common shares, excluding certain defined transactions (for Messrs. Judge, Lembo, Schweiger and Nolan); (iii) a change in the majority of the Eversource Board of Trustees, unless approved by a majority of the incumbent Trustees; (iv) certain reorganizations, mergers or consolidations where substantially all of the persons who were the beneficial owners of the outstanding common shares immediately prior to such business combination do not beneficially own more than 50 percent of the voting power of the resulting business entity (excluding in certain cases defined transactions); and (v) complete liquidation or dissolution of Eversource, or a sale or disposition of all or substantially all of the assets of Eversource other than, for Mr. Butler, to an entity with respect to which following completion of the transaction more than 50 percent of common shares or other voting securities is then owned by all or substantially all of the persons who were the beneficial owners of common shares and other voting securities immediately prior to such transaction.

In the event of a change in control, the Named Executive Officers are generally entitled to receive compensation and benefits following either involuntary termination of employment without “cause” or voluntary termination of employment for “good reason” within the applicable period (generally two years following a change in control). The Compensation Committee believes that termination for good reason is conceptually the same as termination “without cause” and, in the absence of this provision, potential acquirers would have an incentive to constructively terminate executives to avoid paying severance. Termination for “cause” generally means termination due to a felony or certain other convictions; fraud, embezzlement, or theft in the course of employment; intentional, wrongful damage to Eversource property; gross misconduct or gross negligence in the course of employment or gross neglect of duties harmful to Eversource; or a material breach of obligations under the agreement. “Good reason” for termination generally exists after assignment of duties inconsistent with executive’s position, a material reduction in compensation or benefits, a transfer more than 50 miles from the executive’s pre-change in control principal business location (or for Messrs. Judge, Lembo, Schweiger and Nolan, an involuntary transfer outside the greater Boston metropolitan area), or requiring business travel to a substantially greater extent than required prior to the change in control.

The summaries above do not purport to be complete and are qualified in their entirety by the actual terms and provisions of the agreements and plans, copies of which have been filed as exhibits to this Annual Report on Form 10-K.
167



Payments Upon Termination

Regardless of the manner in which the employment of a Named Executive Officer terminates, the executive is entitled to receive certain amounts earned during the executive’s term of employment. Such amounts include:

Vested RSUs and certain other vested awards;
Amounts contributed and any vested matching contributions under the deferred compensation program;
Pay for unused vacation; and
Amounts accrued and vested under the pension/supplemental and 401k programs (except in the event of a termination for cause under the supplemental program).

The following table describes additional compensation payable to the Named Executive Officers in the event of voluntary termination, involuntary termination not for cause, termination in the event of death or disability and termination following a change in control. No benefits are provided in the event of termination for cause. See the section above captioned “Pension Benefits in 2020” for information about the pension program, supplemental program and other benefits, and the section captioned “Nonqualified Deferred Compensation in 2020.”

(2)    For Voluntary Termination and Termination Not For Cause, and Termination Upon Death or Disability: Represents 100 percent of the performance share awards under the 2018 – 2020 Long-Term Incentive Program, 67 percent of the performance share awards under the 2019 – 2021 Long-Term Incentive Program and 33 percent of the performance share awards under the 2020 – 2022 Long-Term Incentive Program.

For Termination Following a Change in Control: Represents actuarial present values at year-end 2020 of amounts payable solely under employment agreements upon termination (which are in addition to amounts due under the pension program). For Messrs. Judge, Schweiger, Nolan and Butler, pension benefits were calculated by adding three years of service (two years for Mr. Lembo). A lump sum of this benefit value is payable to Messrs. Judge, Lembo, Schweiger and Nolan. Pension amounts shown in the table are present values at year-end 2020 of benefits payable upon termination as described with respect to the Pension Benefits Table above.

(5)    The amount noted in the Involuntary Termination, Not for Cause: Represents for Mr. Butler the value of two years’ employer contributions toward active health, long-term disability, and life insurance benefits, plus a payment to offset any taxes thereon. For Termination Following a Change in Control: represents estimated cost to Eversource at year-end 2020 (estimated by consultants) of providing post-employment health and welfare benefits beyond those available to non-executives upon involuntary termination. The amounts shown in the table for Messrs. Judge, Schweiger and Nolan represent the value of three years (two years for Mr. Lembo) of continued health and welfare plan participation. The amounts shown in the table for Mr. Butler represent the value of three years of employer contributions toward active health, long-term disability, and life insurance benefits, plus a payment to offset any taxes on the value of these benefits, less the value of one year of retiree health coverage at retiree rates.

(6)    The amount noted for Involuntary Termination, Not for Cause: Represents the cost to Eversource of reimbursing Mr. Butler for two years of financial planning and tax preparation fees. The amounts noted for Termination Following a Change in Control: Represents the cost to Eversource of reimbursing Messrs.

(7)    For Termination Following a Change in Control: Represents payments made to offset costs associated with certain excise taxes under Section 280G of the Internal Revenue Code. Executives may be subject to certain excise taxes under Section 280G if they receive payments and benefits related to a Termination Following a Change in Control that exceed specified Internal Revenue Service limits. Contractual agreements with the above executives provide for a grossed-up reimbursement of these excise taxes. The amounts in the table are based on the Section 280G excise tax rate of 20 percent, the statutory federal income tax withholding rate of 35 percent, the applicable state income tax rate, and the Medicare tax rate of 1.45 percent.

(8)    For Involuntary Termination, Not for Cause: Represents for Mr. Butler a severance payment (two-times the sum of base salary plus relevant annual incentive award) in addition to any non-compete agreement payment described above. For Termination Following a Change in Control: Represents severance payments in addition to any non-compete agreement payments described in the prior note. For Messrs. Judge, Schweiger and Nolan, this payment equals three-times the sum of base salary plus relevant annual incentive award (two-times the sum for Messrs. Lembo and Butler.) These payments do not replace, offset or otherwise affect the calculation or payment of the annual incentive awards.

(9)    For Involuntary Termination, Not For Cause and Termination Following a Change in Control: Represents payments made under agreements or Eversource programs to Mr. Butler as consideration for agreement not to compete with Eversource following termination of employment, equal to the sum of base salary plus relevant annual incentive award. These payments do not replace, offset or otherwise affect the calculation or payment of the annual incentive awards.

PAY RATIO

Eversource's Chief Executive Officer to median employee pay ratio is calculated pursuant to the requirements of Item 402(u) of Regulation S-K. Eversource identifies a new median employee each year. For 2020, Eversource identified the median employee by reviewing the 2020 total cash compensation of all full-time employees, excluding Eversource’s Chief Executive Officer, who were employed by Eversource and its subsidiaries on December 31, 2020. In Eversource’s assessment of median employee compensation, pay was annualized for those employees who commenced work during 2020. Otherwise, no assumptions, adjustments, or estimates were made with respect to total cash compensation, and the compensation for any full-time employees who were not employed by Eversource at the end of 2020 was not annualized. Eversource believes the use of total cash compensation for all employees is a consistently applied compensation measure, as Eversource does not widely distribute annual equity awards to employees.

After identifying the median employee based on total cash compensation, Eversource calculated the annual total compensation for such employee using the same methodology used for its Named Executive Officers as set forth in the 2020 Summary Compensation Table.

Mr. Judge had 2020 annual total compensation of $14,575,276, as reflected in the Summary Compensation Table. Eversource’s median employee’s annual total compensation for 2020 was $140,054. Eversource’s 2020 Chief Executive Officer to median employee pay ratio is 104 to 1.

Eversource Energy

Incorporated herein by reference is the information contained in the sections captioned "Trustee Independence" and "Related Person Transactions" of Eversource Energy's definitive proxy statement for solicitation of proxies, expected to be filed with the SEC on or about March 26, 2021.22, 2024.

Certain information required by this Item 13 has been omitted for CL&P, NSTAR Electric and PSNH pursuant to Instruction I(2)(c) to Form 10-K, Omission of Information by Certain Wholly-Owned Subsidiaries.

CL&P

Eversource Energy's Code of Ethics for Senior Financial Officers applies to the Senior Financial Officers (Chief Executive Officer, Chief Financial Officer and Controller) of Eversource Energy, CL&P and certain other Eversource Energy subsidiaries.  Under the Code, one's position as a Senior Financial Officer in the company may not be used to improperly benefit such officer or his or her family or friends.  Under the Code, specific activities that may be considered conflicts of interest include, but are not limited to, directly or indirectly acquiring or retaining a significant financial interest in an organization that is a customer, vendor or competitor, or that seeks to do business with the company; serving, without proper safeguards, as an officer or director of, or working or rendering services for an organization that is a customer, vendor or competitor, or that seeks to do business with the company. Waivers of the provisions of the Code of Ethics for Trustees, executive officers or directors must be approved by Eversource Energy's Board of Trustees.  Any such waivers will be disclosed pursuant to legal requirements.

Eversource Energy's Code of Conduct, which applies to all Trustees, directors, officers and employees of Eversource Energy and its subsidiaries, including CL&P, contains a Conflict of Interest Policy that requires all such individuals to disclose any potential conflicts of interest.  Such individuals are expected to discuss their particular situations with management to ensure appropriate steps are in place to avoid a conflict of interest.  All disclosures must be reviewed and approved by management to ensure a particular situation does not adversely impact the individual's primary job and role.

Eversource Energy's Related Persons Transactions Policy is administered by the Corporate Governance Committee of Eversource Energy's Board of Trustees.  The Policy generally defines a "Related Persons Transaction" as any transaction or series of transactions in which (i) Eversource Energy or a subsidiary is a participant, (ii) the aggregate amount involved exceeds $120,000 and (iii) any "Related Persons" has a direct or indirect material interest.  A "Related Persons" is defined as any Trustee or nominee for Trustee, any executive officer, any shareholder owning more than 5 percent of Eversource Energy's total outstanding shares, and any immediate family member of any such person.  Management submits to the Corporate Governance Committee for consideration any Related Persons Transaction into which Eversource Energy or a subsidiary proposes to enter.  The Corporate Governance Committee recommends to the Eversource Energy Board of Trustees for approval only those transactions that are in Eversource Energy's best interests.  If management causes the company to enter into a Related Persons Transaction prior to approval by the Corporate Governance Committee, the transaction will be subject to ratification by the Eversource Energy Board of Trustees.  If the Eversource Energy Board of Trustees determines not to ratify the transaction, then management will make all reasonable efforts to cancel or annul such transaction.

The directors of CL&P are employees of CL&P and/or other subsidiaries of Eversource Energy, and thus are not considered independent.

The Audit Committee pre-approves all auditing services and permitted audit-related or other services (including the fees and terms thereof) to be performed for us by our independent registered public accounting firm, subject to the de minimis exceptions for non-audit services described in Section 10A(i)(1)(B) of the Securities Exchange Act of 1934, which are approved by the Audit Committee prior to the completion of the audit. The Audit Committee may form and delegate its authority to subcommittees consisting of one or more members when appropriate, including the authority to grant pre-approvals of audit and permitted non-audit services, provided that decisions of such subcommittees to grant pre-approvals are presented to the full Audit Committee at its next scheduled meeting.  During 2020,2023, all services described above were pre-approved by the Audit Committee or its Chair.  

The Audit Committee has considered whether the provision by the Deloitte Entities of the non-audit services described above was allowed under Rule 2-01(c)(4) of Regulation S-X and was compatible with maintaining the independence of the registered public accountants and has concluded that the Deloitte Entities were and are independent of us in all respects.
