Change in Accounting Principle
Leases
Lessee
We determine if an arrangementIn the third quarter of 2020, Washington Gas made a voluntary change in accounting principle for calculating the market-related value of assets (MRVA) used in the determination of net periodic pension and other post-retirement benefit plan costs. The change uses the fair value approach for the fixed income investments and related derivatives, which represent a separate asset class of the plan assets, compared to the prior method that utilized a calculated value for all investments where gains and losses arising from changes in fair value were deferred and amortized into the calculation of the MRVA over a period of five years. The MRVA is a leaseused in the calculation of the expected return on assets and the lease classificationrecognized actuarial gain or loss components of net periodic benefit cost. The gains and losses for other plan assets will continue to be deferred and amortized into the MRVA over a five-year period.
We believe that using the fair value approach for the fixed income investments and related derivatives in our plan assets is preferable because the Company will immediately recognize the gains and losses of the fixed income investments and derivatives in MRVA rather than deferring them over a five-year period, which results in a better matching of the change in fixed income investments and the related pension obligations.
We have retrospectively applied this change in accounting principle to all applicable prior period financial information presented herein as required. The change in accounting principle increased retained earnings $9.4 million and decreased accumulated other comprehensive income (loss), net of taxes, $0.4 million, with a net increase of $9.0 million in common shareholder’s equity at inception.

ASU 2016-02, Leases (Topic 842), ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842, ASU 2018-11, Targeted Improvements, and ASU 2018-20, Narrow-Scope Improvements for Lessors, including other subsequent ASUs clarifying the guidance.

ASU 2016-02 requires recognition of a right-to-use asset and lease liability by lessees on the statement of financial position and disclosure of key information about leasing arrangements. Lessor accounting remains substantially unchanged but the standard modifies what qualifies as a sales-type and direct financing lease and eliminated real-estate specific provisions. The standard requires application using a modified retrospective approach.

ASU 2018-01 provides an optional election not to evaluate existing and expired land easements not previously accounted for as a lease.

ASU 2018-11 allows entities to elect to report comparative periods presented after adoption under the old lease standard (ASC Topic 840, Leases) and recognize a cumulative effect adjustment to the opening balance at the date of adoption. The update also provides lessors a practical expedient not requiring the separation of lease and non-lease components provided that certain conditions are met.

ASU 2018-20 allows lessors to include and exclude certain costs from variable payments. The ASU also requires lessors to allocate certain variable payments to the lease and non-lease components when the changes in facts and circumstances on which the variable payments are based occur.


January 1, 2019
Leases, with terms longer than 12 months, for which Washington Gas is the lessee have been reflected on the balance sheet by recording an increase to non- current assets and an increase to deferred credits net of the current portion that is recorded in current liabilities. Upon adoption, Washington Gas recorded lease liabilities of $58.9 million and a right-of-use asset of $43.2 million, net of lease incentives and prepaid or deferred rent balances of $15.7 million.  Washington Gas utilized the transition practical expedients which allow entities to not have to reassess whether an arrangement contains a lease and the lease classification under the provisions of ASC Topic 842, land easements, and not separating out the lease and non-lease components for certain classes of assets. As a result of the transition practical expedients, Washington Gas’ operating leases on transition are consistent with its conclusions under ASC 840.  Washington Gas has also elected to present prior comparative information under ASC 840. See Note 3 - Leases for further information and the new required lease disclosures.

ASU 2017-12 amends the hedge accounting and recognition requirements by expanding an entity’s ability to hedge non-financial and financial risk components and reduce the complexity in fair value hedges of interest rate risk. Additionally, this standard eliminates the requirement to separately measure and disclose the ineffective portion of the hedge with the entire change in the fair value of a hedging instrument to be presented in the same statement of operations line as the hedged item. Early adoption is permitted.

ASU 2018-16 adds the OIS rate based on SOFR as a fifth U.S. benchmark interest rate for hedge accounting purposes. This standard should be adopted in conjunction with ASU 2017-12 if not early adopted.

Capitalized implementation costs should be presented in the statement of financial position as a prepaid expense and amortized over the term of the hosting arrangement, presented in the statements of operations in the same line items as prepayment of fees associated with the hosting arrangement. The updates in this standard may be applied on a prospective or retrospective basis. Early adoption is permitted.January 1, 2019We early adopted this standard on a prospective basis.

NOTE 2. REVENUE FROM CONTRACTS WITH CUSTOMERS
CREDIT LOSSES

TheOn January 1, 2020, the Company adopted ASU 2014-09, Revenue2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (CECL) model. The measurement of expected credit losses under the CECL model is applicable to financial assets measured at amortized cost and off-balance sheet credit exposures. The CECL model requires the expected credit losses to consider past events, including historical experience, current conditions and reasonable and supportable forecasts. When measuring credit losses, financial assets with similar risk characteristics should be pooled, and credit losses should be recognized over the contractual term of the financial asset. In addition, entities may make a one-time irrevocable election on certain eligible financial instruments to elect fair-value treatment on an instrument-by-instrument basis.
Our assessment concluded that our cash equivalents, accounts receivables, unbilled revenue, contract assets, and a long term receivable from Contracts with Customers (Accounting Standard Codification (ASC) 606) and subsequent ASUs clarifyingone of our trading partners that is part of a collaborative arrangement are within scope of the guidance on October 1, 2018,new standard. We adopted the standard using the modified retrospective method of adoption. Under thisa modified-retrospective approach prior year results are not required to be restated. Adoption of this standard did not change the timing or pattern of revenue recognition andthrough a cumulative-effect adjustment wasto retained earnings at January 1, 2020. Prior periods presented for comparative purposes are not adjusted. Upon implementation of ASU 2016-13, we recorded a $1.5 million increase to the Company's allowance for doubtful accounts and a decrease to retained earnings, including a $1.4 million increase to allowance for doubtful account associated with utility customer receivables and a $0.1 million reduction to “Deferred charges and other assets-Other” associated with a long-term receivable from a trading partner under Washington Gas' asset optimization programs. Washington Gas also elected to account for its cash equivalents at fair value.
Utility Customer Receivables: Washington Gas is exposed to customer credit risk resulting from the non-payment of utility bills. To manage this customer credit risk, Washington Gas customers are offered budget billing options or higher risk customers may be required to provide a cash deposit until the requirement for deposit refunds are met. Washington Gas can recover a portion of non-payments from customers in future periods through the rate-setting process. For accounts receivable and unbilled revenue generated by the utility business, an allowance for doubtful accounts is recognized using a historical loss-rate based on historical payment and collection experience. This rate may be adjusted based on management’s expectations of unusual macroeconomic conditions and other factors. Washington Gas regularly evaluates the reasonableness of the allowance based on a combination of factors, such as the length of time receivables are past due, historical expected payment, collection experience, financial condition of customers, and other circumstances that could impact customers' ability or desire to make payments.
Based on previous collection experience, Washington Gas has not recorded upon adoption.an allowance for doubtful accounts for its contract assets associated with our energy management services projects with the federal government. Refer to Note 14 Related Party Transactions for further information.
Washington Gas Asset Optimization: The Utility operates under an existing wholesale counterparty credit policy that is designed to mitigate credit risk. Credit limits are established for each counterparty and credit enhancements such as letters of credits, parent guarantees and cash collateral maybe required. The creditworthiness of all counterparties is continuously monitored. The allowance for doubtful accounts is estimated by applying 30-year historical default rates for one-year receivables sourced from external credit rating agencies to the accounts receivable and unbilled revenue balances associated with counterparties the Utility has determined to be below investment grade. In the event that a counterparty no longer exhibits similar risk characteristics, the associated receivable is evaluated individually.
Washington Gas also has a long-term receivable from a trading partner totaling $1.4 million in “Deferred charges and other assets Other”, of which no portion of the balance is past due. The trading partner was evaluated and assigned an internal credit rating in accordance with our credit policy. An allowance for doubtful accounts is recorded based on historical default rates published by external credit rating agencies and a rate commensurate with the period in which the receivable is expected to be collected. Estimated credit loss reserve was recorded as a reduction to “Deferred charges and other assets Other”.

COVID-19: On March 11, 2020, the World Health Organization declared the outbreak of a strain of novel coronavirus disease, COVID-19, a global pandemic. Governments in affected areas in which we operate have imposed a number of measures designed to contain the outbreak, including business closures, travel restrictions, quarantines and cancellations of gatherings and events. These measures have resulted in widespread challenges to businesses and the job market. The increased unemployment rates could impact the ability of the Company’s customers to pay for services. As a result comparative disclosuresof regulatory orders, we have temporarily suspended customer disconnections for operating results fornon-payment, temporarily suspended collection activities and temporarily waived assessing and billing late payment fees. We resumed assessing late payment fees in Maryland in October 2020 following a regulatory order. The suspension of collection activities has caused our overall accounts receivable portfolio to age more than historical levels. However, we do not expect the increase in credit losses to have a significant impact on net income. In addition, the Public Service Commission of the District of Columbia (PSC of DC), the Public Service Commission of Maryland (PSC of MD) and the Virginia State Corporation Commission (SCC of VA) each issued an Order authorizing Washington Gas to establish a regulatory asset to capture and track the incremental COVID-19 related costs. For the three and nine months ended September 30, 2019 are not applicable because implementing2020, Washington Gas has recorded total $4.7 million and $7.7 million in deferrals of incremental bad debt expense to COVID-19 regulatory assets across all three jurisdictions, respectively.
As of September 30, 2020, we have evaluated the new standard did not changeadequacy of our allowance for credit losses in light of the timing or patternsuspension of revenue recognition.shut-offs for nonpayment due to COVID-19 and the economic downturn. Our evaluation included an analysis of customer payment trends in 2020, economic conditions, receivables aging, and considerations of past economic downturns, the actions the company is taking to assist customers with past due balances, and the corresponding allowance for credit losses and customer account write-offs. Based on this evaluation, we have concluded that the allowance for credit losses as of September 30, 2020 adequately reflected the collection risk and net realizable value for our receivables. We will continue to monitor changing circumstances and will adjust our allowance for credit losses as additional information becomes available.

NOTE 3. REVENUE FROM CONTRACTS WITH CUSTOMERS
The Company recognizes revenue from contracts with customers to depict the transfer of goods or services to customers at an amount it expects to be entitled to in exchange for those goods or services. Washington Gas sells natural gas and distribution services to residential, commercial, industrial and governmental customers through regulated tariff rates approved by regulatory commissions in the jurisdictions where it operates (District of Columbia, Maryland, and Virginia).operates. Customers are billed monthly based on regular meter readings. Customer billings are based on two main components: (i) a fixed service fee and (ii) a variable fee based on usage. For customers who choose to purchase their natural gas from Washington Gas, the bill will include a usage based charge for the cost of the commodity. Revenue is recognized over time as the natural gas is delivered or as the service is performed. AsSince meter readings are performed on a cycle basis, Washington Gas recognizes accrued revenue for any services rendered to its customers but not billed at month-end. The tariff sales are generally considered daily or “at-will” contracts as customers may cancel their service at any time (subject to notification requirements in the tariff), and revenue generally represents the amount Washington Gas is entitled to invoice. There are certain contracts that have terms of one year or longer. For these contracts, revenue is recognized based on the amount Washington Gas is entitled to bill the customer.
Customers have the choice to purchase natural gas from competitive service providers. Washington Gas charges the competitive service providers balancing fees to manage the natural gas transportation imbalances. Where regulations require, Washington Gas issues customers a consolidated bill to include the natural gas supplied by the competitive service providers and distribution of natural gas.

ashington Gas has an unconditional right to payment, except for contract assets related to Washington Gas’ area-wide contract, which requires project acceptance by the federal government for the right to payment to occur. As of September 30, 2019, contract assets of $40.5 million have been recorded for financed projects within “Unbilled revenues” on the condensed balance sheets. Washington Gas did not have any contract liabilities at September 30, 2020 and 2019. The Company does not have transaction price amounts allocated to future performance obligations. The Company applies the practical expedient available under ASC Topic 606 and does not disclose information about the remaining performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts for which revenue is recognized at the amount to which the Company has the right to invoice for performance completed, and (iii) contracts with variable consideration that is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct good or service that forms part of a single performance obligation.
The following table shows the opening and closing balances of contract assets from contracts with customers for the reporting periods, which were included within "Receivables" on Washington Gas' balance sheets.

On January 1,(a) Decrease in contract asset in 2019 was due to the Company adopted ASU 2016-02, Leases (ASC 842) and the following subsequent ASUs which amended the guidance: ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842, ASU 2018-10, Codification Improvements, and ASU 2018-11, Leases Targeted Improvements, and ASU 2018-20, Narrow-Scope Improvements for Lessors. The new leasing standard requires lessees to recognize a ROU asset and lease liability for leases classified as an operating lease. The significant effects of adopting this standard and the qualitative and quantitative disclosures required to enable userssale of the financial statementscontract asset. Refer to assess the amount, timing, and uncertainty of cash flows arising from leases are included"Project financing" in Note 1-Accounting Policies and below.14 Related party transactions for detail discussion.
Adoption of the new standard had a material impact to our balance sheet but did not have a material impact to our statement of operations. On January 1, 2019, the Company recorded ROU assets of $43.2 million (net of lease incentives and prepaid or deferred rent of $15.7 million), current lease liability of $2.8 million and non-current lease liability of $56.1 million related to our operating leases. The Company currently does not have finance leases. We elected to implement the new leasing standard retrospectively at the beginning of the period of adoption through a cumulative-effect adjustment. Under this approach, prior year results are not required to be restated and disclosures associated with prior periods are reported under ASC 840.

Lessee Leases
The Company elected to use the transition practical expedient which allows an entity not to reassess whether any expired or existing contracts are, or contain, leases; the lease classification for any expired or existing leases; and the initial direct costs for any existing leases. The practical expedient also allows an entity not to reassess whether existing or expired land easements that were not previously accounted for as a lease under Topic 840 was also elected. The Company elected not to separate lease and non-lease components for its building leases and has elected not to record a ROU asset and lease liability for short-term leases. Short-term leases are defined as leases with a term of 12 months or less at the commencement date, including extension options that are reasonably certain of being exercised, and do not include an option to purchase the underlying asset. Short-term lease costs for the period were not material.
Washington Gas has operating leases for our corporate headquarters and other corporate offices, communication tower space, and certain office equipment. Our leases have remaining lease terms from 1 to 22 years. Some of the leases include options to extend the lease terms for 1 to 5 years with prior written notice or automatically renew if either party does not provide intent to terminate. The leases generally have options to terminate with notice prior to the end of the lease term based on the contract terms. Refer to Note 13-Related Party Transactions for discussion of leases with associated companies.

representing the government’s obligation to remit principal and interest, and recorded a “Payable to associated company” to WGL Energy Systems for the construction work performed for the same amount. WGL Energy Systems now directly obtains third-party project financing for its energy management services projects. As work is performed, Washington Gas establishes a contract asset in “Unbilled revenue” representing the government’s obligation to remit principal and interest and records a “Payable to associated company” to WGL Energy Systems for the construction work performed for the same amount.
As of September 30, 2019, Washington Gas recorded $40.5 million of contract assets in “Unbilled revenues” and a $40.5 million payable to WGL Energy Systems in “Payables to associated companies,” respectively, for energy management services projects financed by WGL Energy Systems that were not complete. There was no project financing obligation on Washington Gas’ balance sheet as of September 30, 2019.
As of December 31, 2018, Washington Gas recorded $85.3 million of contract assets in “Unbilled revenues,” $15.5 million in a corresponding short-term financing to third-party lenders in “Notes payable and project financing,” and $69.7 million accounts payable to WGL Energy Systems in “Payables to associated companies” for energy management services projects that were not complete.
In October 2018, WGL Energy Systems repaid $53.0 million drawn by Washington Gas from a third-party lender for a specific project for which the lender demanded repayment due to delays in achieving final acceptance from the federal government agency customer. The $53.0 million was included in “Payables to associated companies” on Washington Gas’ balance sheet as of December 31, 2018. On January 16, 2019, the federal government agency customer provided notification of final acceptance as of December 14, 2018. In February 2019, WGL sold the receivables, and accordingly, Washington Gas reversed the associated amount in “Payables to associated companies” and “Unbilled revenue” on its balance sheet.
Washington Gas did not record a corresponding reserve for bad debts related to these contract assets at September 30, 2019 and December 31, 2018, based on our previous collection experience with receivables that have been financed for government agencies with minimal credit risk.

Silver Spring, Merger Commitments
In connection with the Merger, Washington Gas and AltaGas have made commitments related to the terms of settlement agreement with PSC of DC and the conditions of approval from PSC of MD and SCC of VA. As of September 30, 2020, the remaining unpaid liability for previously expensed merger commitments was $15.9 million.

Additionally, there are a number of operational commitments that have an impact on the ongoing business of Washington Gas, including reductions of leak backlogs, conducting a root cause analysis related to customer service, increasing supplier diversity, achieving synergy savings benefits, developing protocols for moving meters from inside to outside customers’ premises, as well as reporting and tracking related to all the commitments.
Contingencies
We account for contingent liabilities utilizing ASC Topic 450, Contingencies. By their nature, the amount of the contingency and the timing of a contingent event and any resulting accounting recognition are subject to our judgment of such events and our estimates of the amounts. Actual results related to contingencies may be difficult to predict and could differ significantly from the estimates included in reported earnings.
Antero Contract
In June 2019, a jury trial was held in the County Court for Denver, Colorado to consider a contractual dispute relating to gas pricing between Washington Gas and its affiliate WGL Midstream and Antero Resources Corporation (Antero). Following the trial, the jury returned a verdict in favor of Antero for $95.9 million, of which $11.2 million was against Washington Gas, and $84.7 million against WGL Midstream. Following the official entry of the judgment, the Company filed an appeal on August 16, 2019. Arguments on the appeal occurred on November 4, 2020.
As a result of this verdict, it was determined that a loss contingency is probable and Washington Gas recorded an estimated liability and recognized a loss in June 2019. In addition, Washington Gas recorded a receivable from our trading partner, and a receivable related to sharing with our customers as the contract relates to asset optimization. Washington Gas has been accruing interest expense on a monthly basis associated with the liability since June 2019. At September 30, 2020, the estimated liability with court fees and accrued interest was $12.3 million recorded in “Accounts payable and accrued liabilities” on Washington Gas' balance sheets. The net receivable from our trading partner was $1.3 million in “Deferred charges and other assets-Other”, and sharing with customers was $5.0 million in “Regulatory assets - Gas costs” on the balance sheets. For the nine months ended September 30, 2020 the interest expense associated with the legal liability was immaterial. For the nine months ending September 30, 2019, the net pre-tax loss recorded as a result of the verdict was $3.0 million in “Utility cost of gas” on Washington Gas’ statements of operations.

Regulatory Contingencies
Certain legal and administrative proceedings incidental to our business, including regulatory contingencies, involve Washington Gas. In our opinion, we have recorded an adequate provision for probable losses or refunds to customers for regulatory contingencies related to these proceedings.
Maryland Incident
Show-Cause OrderOn April 23, 2019, the National Transportation and Safety Board (NTSB) held a hearing during which it found, among other things, that the probable cause of the August 10, 2016, explosion and fire at an apartment complex on Arliss Street in Silver Spring, Maryland “was the failure of an indoor mercury service regulator with an unconnected vent line that allowed natural gas into the meter room where it accumulated and ignited from an unknown ignition source. Contributing to the accident was the location of the mercury service regulators where leak detection by odor was not readily available.” Washington Gas disagrees with the NTSB’s probable cause findings. Following this hearing, on June 10, 2019, the NTSB issued an accident report.
In connection withFollowing the incident, a total of 37 civil actions related to the incident have been filed and are pending against WGL and Washington Gas in the Circuit Court for Montgomery County, Maryland. All cases have been consolidated for discovery purposes. All of these suits seek unspecified damages for personal injury and/or property damage. A trial date for eight bellwether civil actions has been scheduled for December 2, 2019. In addition, two suits were recently filed related to the incident, one each in the Superior Court for the District of Columbia and one in the Circuit Court of Montgomery County, Maryland.
At this stage of the litigation, the outcome is not yet determinable and management is unable to make an estimate of any potential loss or range of potential losses that are reasonably possible of occurring. As a result, management has only recorded a reserve for a few of the actions for which a settlement offer was made. Washington Gas maintains excess liability insurance coverage from highly-rated insurers, subject to a nominal self-insured retention. Washington Gas believes that this coverage will be sufficient to cover any significant liability that may result from this incident.
Regulatory Contingencies
Certain legal and administrative proceedings incidental to our business, including regulatory contingencies, involve Washington Gas. In our opinion, we have recorded an adequate provision for probable losses or refunds to customers for regulatory contingencies related to these proceedings.
Merger Commitments
In connection with the Merger, AltaGas and WGL made commitments related to the terms of the Public Service Commission of the District of Columbia (PSC of DC) settlement agreement and the conditions of approval from the Public Service Commission of Maryland (PSC of MD) and the State Corporation Commission of Virginia (SCC of VA). Among other things, these commitments include rate credits distributable to both residential and non-residential customers, gas expansion and other programs, various public interest commitments, and safety programs. The cumulative amount expensed as of September 30, 2019 was $136.6 million, of which $118.7 million has been paid, including $1.1 million and $7.6 million paid in the three and nine months ended September 30, 2019, respectively. In March 2019, the PSC of MD directed that the $3.9 million Most Favored Nation adjustment, originally recorded as a commitment expense, should be used to offset future rates under Washington Gas’ natural gas expansion program in Maryland. As a result, Washington Gas reversed the commitment expense in the fi

rst quarter of 2019. Further, there are additional regulatory commitments that will be recorded when the costs are incurred in the future, including the hiring of damage prevention trainers in each jurisdiction for a total amount of $2.4 million over 5 years; investing up to $70.0 million over a 10 year period to further extend natural gas service; and spending $7.5 million for leak mitigation within three years of the Merger close.
Application for Approval of Reduction of Distribution Rates
On January 12, 2018, Washington Gas filed applications to reduce customer rates in Maryland, Virginia, and the District of Columbia to reflect the impact of the Tax Act, including both the impact of the re-measurement of deferred tax assets and liabilities and reduction of the federal tax rate to 21%. Washington Gas began tracking the impact of the Tax ActNTSB hearing, on revenue requirements beginning January 1, 2018, recording all impacts to regulatory assets and liabilities. In Maryland and the District of Columbia, rates have been adjusted for the impact of the Tax Act. In Virginia, the SCC of VA dismissed the application on March 15, 2018. Washington Gas filed a new general rate case on July 31, 2018 incorporating the effects of the Tax Act. On September 16, 2019, the Hearing Examiner (HE) issued a report to the SCC of VA recommending the Company increase its liability balance for the Tax Act to $35.4 million and for it to be refunded to customers in a one-time sur-credit. Accordingly, at September 30, 2019, Washington Gas recorded an $18.9 million adjustment to the liability and will refund the credits after the SCC of VA’s final order is issued. See the discussion below for a further discussion of the HE’s report.
Virginia Jurisdiction
Virginia Rate Case. On July 31, 2018, Washington Gas filed an application with the SCC of VA to increase its base rates for natural gas service by $37.6 million, which includes $14.7 million of revenue associated with natural gas pipeline replacement initiatives previously approved by the SCC of VA and paid by customers through a monthly rider. Additionally, the requested revenue increase incorporated the effects of The Tax Act. Interim rates became effective, subject to refund, for usage in the January 2019 billing cycle. On April 12, 2019, Washington Gas filed rebuttal testimony and revised its original return on equity down from 10.6% to 10.3% and its overall rate of return down from 7.94% to 7.81%. Evidentiary hearings were held on April 30 and May 1, 2019. Post hearing briefs were filed on July 3, 2019. On September 16, 2019, the HE issued a report to the SCC of VA which recommended among other things: (i) no increase in base rate revenue; (ii) a return on equity of 9.2% compared to the current authorized return on equity rate of 9.5%; (iii) unprotected plant-related and non-plant-related excess deferred income tax should be amortized as a reduction in rates over 5 years compared to amortizing using Average Rate Assumption Method (ARAM) and over 15 years, respectively; (iv) refund $5.6 million to customers for tax savings related to the October 2017 to December 2017 period as part of the Tax Act savings owed to customer, and (v) write off a $7.1 million regulatory asset related to flowthrough income taxes that the company had recovered previously flowed through depreciation income tax deductions via the SAVE rider. For the nine months ended September 30, 2019, Washington Gas made the following pre-tax adjustments based on the HE’s recommendations: (i) reduced “Operating revenues-Utility” by $7.6 million to accrue additional amounts of liability subject to refund; (ii) reduced “Operating revenues-Utility” by $13.3 million associated with the revised amortization of the Tax Act liability; and (iii) wrote off $2.0 million in “Regulatory Assets - Other” and charged to “Operation and maintenance” expense. Additionally, the Company reduced income tax expense by $11.8 million related to the amortization of excess deferred income tax, and recorded a $5.5 million after-tax impairment of a tax regulatory asset related to flowthrough income taxes. Reply comments on the HE’s report were filed by Washington Gas on October 21, 2019. Washington Gas filed reply comments challenging eleven recommendations contained in the HE’s report, including some of the items highlighted above, where the bases for the findings either disregard or are contrary to the substantial evidentiary record.
Maryland Jurisdiction
Maryland Show-Cause Order. On September 5, 2019, the PSC of MD ordered the Company, within 30 days, to (i) provide a detailed response to the NTSB’s probable cause findings, and (ii) provide evidence regarding the status of a 2003 mercury regulator replacement program, and if the program was not completed, to show cause why the Commission should not impose a civil penalty on the Company. On September 16, 2019,
The Company timely responded to the PSC of MD granted the Company a 14-day extension to file its Response to theMD’s Show-Cause Order. On October 18, 2019, the Company filed its Response to the Show-Cause Order, (i) providing a detailed response to the NTSB’s probable cause findings, and (ii) providing evidence regarding the status of aits 2003 mercury regulator replacement program and demonstrating cause why the CommissionPSC of MD should not impose a civil penalty on the Company. Following the Company’s response, certain intervenors filed written comments and a public hearing was held on the matter, with some intervenors and members of the public advocating for penalties against the Company. The Company filed its rejoinder comments and the Show-Cause Order is working its way through the regulatory proceeding process with the PSC of MD has not adopted a procedural schedule with respect to this matter but has indicatedMD. An evidentiary hearing was conducted on September 24 – 25, 2020. Initial briefs were filed on October 28, 2020 and reply briefs will be filed on November 13, 2020.
Management believes that it will schedule one public hearing near the apartment complex at Arliss Street. Given the early stage of the Show-Cause proceeding, the outcome is not yet determinable and management is unable to predict the likelihood of a civil penalty or make an estimate of any potential civil penalty or range of potential civil penalty.

Financial Guarantees
At September 30, 2019 and December 31, 2018, there were no guarantees to external parties.

Antero Contract

In June 2019, a jury trial was held in the County Court for Denver, Colorado to consider a contractual dispute relating to gas pricing between Washington Gas and WGL Midstream (together, the Companies) and Antero Resources Corporation (Antero). Following the trial, the jury returned a verdict in favor of Antero for $95.9 million, of which $11.2 million was against Washington Gas, and $84.7 million against WGL Midstream. Following the official entry of the judgment, the Company filed an appeal on August 16, 2019.
As a result of this verdict, it was determined that a loss contingency is probable and Washington Gas has recorded an estimatedaccrued $330,000 to reflect the minimum liability of $11.2 million in “Accounts payable and accrued liabilities” on the balance sheet as of September 30, 2019, of which $2.6 million had already been recorded in a prior period. Washington Gas has also recorded a receivable from our trading partner of $1.3 million net in “Accounts payable and accrued liabilities” and sharing with customers as the contract relates to asset optimization of $4.5 million in “Deferred charges and other assets - Gas costs”. In addition, Washington Gas has recorded an accrual for estimated court fees of $0.1 million, and an accrual of interest expense associated with the liability.
For the nine months ending September 30, 2019, the net pre-tax loss recorded as a result of delinquent mercury regulator replacement status reporting. Though the verdict was $3.0Company is unable to estimate the maximum possible penalty, other parties have recommended penalties ranging from $620,500 (PSC of MD Staff, which argued the Company should pay a minimum penalty for failing to provide annual reports detailing progress in replacing the mercury regulators) to $123.3 million in “Utility cost(Office of gas”People's Counsel, which argued the Company should absorb all costs of removal and relocation of mercury service regulators and pay a fine of $25,000 per day for each day mercury service regulators remain on Washington Gas’ statements of operations. the Company’s system).
Environmental Matters
We are subject to federal, state and local laws and regulations related to environmental matters. These laws and regulations may require expenditures over a long time frame to control environmental effects. Almost all of the environmental liabilities we have recorded are for costs expected to be incurred to remediate sites where we or a predecessor affiliate operated manufactured gas plants (MGPs).
Washington Gas has identified up to ten sites where it or its predecessors may have operated MGPs. Washington Gas last used any such plant in 1984. In connection with these operations, we are aware that coal tar and certain other by-products of the gas manufacturing process are present at or near some former sites and may be present at others.
At September 30, 20192020 and December 31, 2018,2019, Washington Gas reported a liability of $10.4 million and $10.7 million, and $11.3 millionrespectively, on an undiscounted basis related to future environmental response costs. These estimates principally include the minimum liabilities associated with a range of environmental response costs expected to be incurred. At both September 30, 20192020 and December 31, 2018,2019, Washington Gas estimated the maximum liability associated with all of its sites to be approximately $35.8 million and $29.4 million, respectively.$30.7 million. The estimates were determined by Washington Gas’ environmental experts, based on experience in remediating MGP sites and advice from legal counsel and environmental consultants. The variation between the recorded and estimated maximum liability primarily results from differences in the number of years that will be required to perform environmental response processes and the extent of remediation that may be required.
Washington Gas is currently remediating its East Station property, located in Washington D.C. adjacent to the Anacostia River in Washington D.C., including ground water pump and treat, tar recovery, soil encapsulation and other treatment. Under a 2012 consent decree with the District of Columbia and the federal government, Washington Gas is also conducting a remedial investigation and feasibility study on an adjacent property owned by the District of Columbia. The Draft Remedial Investigation Report was submitted to the National Park Service (NPS) and the Department of Energy and Environment (DOEE) on June 12, 2020. Additional remediation may be required at this property.

Washington Gas received a letter in February 2016 from the DOEE and National Park Service regarding the Anacostia River Sediment Project, indicating that the District of Columbia is conducting a separate remedial investigation and feasibility study of the river to determine if and what cleanup measures may be required and to prepare a natural resource damage assessment. The sediment project draft remedial investigation reportOn December 27, 2019, DOEE issued on March 30, 2018an Anacostia River Sediment Project Proposed Plan, a River-wide Feasibility Study, and supporting documents for public comment. Although the Proposed Plan identifies East Station as one of seventeenfifteen potential environmental cleanup sites.sites, DOEE is proposing to continue the remediation of East Station under Washington Gas’ existing Consent Decree rather than as part of the Anacostia River Sediment Project. DOEE issued an Interim Record of Decision for remediation of “Early Action Areas” (that do not include East Station) in the Anacostia River by September 30, 2020. We are not able to estimate the total amount of potential damagescosts or timing associated with the District of Columbia’s environmental investigation on the Anacostia River at this time. While an allocation method has not been established, Washington Gas has accrued an amount for estimated study costs based on a potential range of estimates.

NOTE 11.12. DERIVATIVES
Derivative Instruments
Washington Gas enters into contracts that qualify as derivative instruments and are accounted for under ASC Topic 815. These derivative instruments are recorded at fair value on our balance sheetsheets and Washington Gas does not currently designate any derivatives as hedges under ASC Topic 815. Washington Gas’ derivative instruments relate to: (i) Washington Gas’ asset optimization program; (ii) managing price risk associated with the purchase of gas to serve utility customers and (iii) managing interest rate risk.
Asset Optimization.Washington Gas optimizes the value of its long-term natural gas transportation and storage capacity resources during periods when these resources are not being used to physically serve utility customers. Specifically, Washington Gas utilizes its transportation capacity assets to benefit from favorable natural gas prices between different geographic locations and utilizes its storage capacity assets to benefit from favorable natural gas prices between different time periods. As part of this asset optimization program, Washington Gas enters into physical and financial derivative transactions in the form of forward, futures and option contracts with the primary objective of securing operating margins that Washington Gas will ultimately realize. The derivative transactions entered into under this program are subject to mark-to-market accounting treatment under ASC Topic 820.
Regulatory sharing mechanisms provide for the annual realized profit from these transactions to be shared between Washington Gas’ shareholdersshareholder and customers; therefore, changes in fair value are recorded through earnings, or as regulatory assets or liabilities to the extent that it is probable that realized gains and losses associated with these derivative transactions will be included in the rates charged to customers when they are realized. Unrealized gains and losses recorded to earnings may cause significant period-to-period volatility; this volatility does not change the operating margins that Washington Gas expects to ultimately realize from these transactions through the use of its storage and transportation capacity resources.
Washington Gas has a collaborative arrangement with a third party to facilitate the asset optimization program. The collaborative arrangement allocates a tiered percentage of profits or losses to the third party as compensation for its participation. The costs recorded by Washington Gas related to the collaborative arrangement totaled $2.4 million and $2.5 million for the three months ended September 30, 2020 and 2019, respectively, and $5.8 million and $3.8 millionfor the nine months ended September 30, 2020 and 2019, respectively. These amounts were recorded in “Utility cost of gas” on Washington Gas’ statements of operations. Either party may terminate the collaborative arrangement through the delivery of a termination notice. In such an event, Washington Gas may make a payment upon termination.
All physically and financially settled contracts under our asset optimization program are reported on a net basis in the statements of operations in “Utility cost of gas.”gas”. Total net margins recorded to “Utility cost of gas” after sharing and management fees associated with all asset optimization transactions for the three months ended September 30, 2020 was a net gain of $5.1 million including an unrealized loss of $1.3 million. During the three months ended September 30, 2019, waswe recorded a net loss of $1.2 million including an unrealized loss of $6.5 million.million . During the threenine months ended September 30, 2018,2020, we recorded a net gain of $7.7$19.7 million including an unrealized gain of $3.3$5.5 million. Total net margins recorded to “Utility cost of gas” after sharing and management fees associated with all asset optimization transactions forDuring the nine months ended September 30, 2019, waswe recorded a net gain of $8.3 million including an unrealized gain of $0.1 million and athe $3.0 million loss related to the Antero Contract. During the nine months ended September 30, 2018, we recorded a net gain of $28.5 million including an unrealized gain of $11.8 million. Refer to Note 10-11 - Commitments and Contingencies for further discussion of the Antero Contract.
Managing Price Risk.To manage price risk associated with acquiring natural gas supply for utility customers, Washington Gas enters into physical and financial derivative transactions in the form of forward, option and other contracts, as authorized by its regulators. Any gains and losses associated with these derivatives are recorded as regulatory liabilities or assets, respectively, to reflect the rate treatment for these economic hedging activities.
Managing Interest-Rate Risk. Washington Gas may utilize derivative instruments that are designed to minimize the risk of interest-rate volatility associated with planned issuances of debt securities. Any gains and losses associated with these types of derivatives are recorded as regulatory liabilities or assets, respectively, and amortized in accordance with regulatory requirements, typically over the life of the related debt. As of September 30, 2019 and December 31, 2018, Washington Gas does not have any interest rate swaps in derivatives.

Collateral
Washington Gas utilizes standardized master netting agreements, which facilitate the netting of cash flows into a single net exposure for a given counterparty. As part of these master netting agreements, cash, letters of credit and parent company guarantees may be required to be posted or obtained from counterparties in order to mitigate credit risk related to both

Any collateral posted that is not offset against derivative assets and liabilities is included in “Other prepayments” inon the condensed balance sheet.sheets. Collateral received and not offset against derivative assets and liabilities is included in “Customer deposits and advance payments” inon the accompanying condensed balance sheet.sheets.
At September 30, 20192020 and December 31, 2018,2019, Washington Gas had $3.3$1.0 million and $7.4$5.2 million, respectively, in collateral deposits posted with counterparties that are not offset against derivative asset and liabilities. At September 30, 20192020 and December 31, 2018,2019, Washington Gas had $0.1 million and $0.2$0.1 million, respectively, cash collateral held representing an obligation, and are not offset against derivative asset and liabilities.
Certain derivative instruments of Washington Gas contain contract provisions that require collateral to be posted if the credit rating of Washington Gas falls below certain levels or if counterparty exposure to Washington Gas exceeds a certain level (credit-related contingent features). At September 30, 20192020 and December 31, 2018,2019, Washington Gas was notrequired to post collateral related to a derivative liability that contained a credit-related contingent feature.

NOTE 12.13. FAIR VALUE MEASUREMENTS
We measure the fair value of our financial assets and liabilities using a combination of the income and market approaches in accordance with ASC Topic 820. These financial assets and liabilities primarily consist of derivatives recorded on our balance sheetsheets under ASC Topic 815 and short-term investments, other long-term receivable, commercial paper and long-term debt outstanding required to be disclosed at fair value. Under ASC Topic 820, fair value is defined as the exit price, representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To value our financial instruments, we use market data or assumptions that market participants would use, including assumptions about credit risk (both our own credit risk and the counterparty’s credit risk) and the risks inherent in the inputs to valuation.
We enter into derivative contracts in the futures and over-the-counter (OTC) wholesale and retail markets. These markets are the principal markets for the respective wholesale and retail contracts. Our relevant market participants are our existing counterparties and others who have participated in energy transactions at our delivery points. These participants have access to the same market data as Washington Gas. Valuations are generally based on pricing service data or indicative broker quotes depending on the market location. We measure the net credit exposure at the counterparty level where the right to set-off exists. The net exposure is determined using the mark-to-market exposure adjusted for collateral, letters of credit and parent guarantees. We use published default rates from Standard & Poor’s Ratings Services and Moody’s Investors Service as inputs for determining credit adjustments.
ASC Topic 820 establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three levels of the fair value hierarchy under ASC Topic 820 are described below:
Washington Gas Light Company
Part I-Financial Information
Item 1-Financial Statements (continued)
Notes to Condensed Financial Statements (Unaudited)

Level 1.  Level 1 of the fair value hierarchy consists of assets or liabilities that are valued using observable inputs based upon unadjusted quoted prices in active markets for identical assets or liabilities at the reporting date. Washington Gas did not have any Level 1 derivativesIncluded in this category are cash equivalents and Rabbi trust investments in money market funds which are recorded on the balance sheets at September 30, 2019 or December 31, 2018.fair value on a recurring basis.
Level 2. Level 2 of the fair value hierarchy consists of assets or liabilities that are valued using directly or indirectly observable inputs either corroborated with market data or based on exchange traded market data. Level 2 includes fair values based on industry-standard valuation techniques that consider various assumptions: (i) quoted forward prices, including the use of mid-market pricing within a bid/ask spread; (ii) discount rates; (iii) implied volatility and (iv) other economic factors. Substantially all of these assumptions are observable throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the relevant market. At September 30, 2019 and December 31, 2018, Level 2 financial assets and liabilities included energy-related physical and financial derivative transactions such as forward, option and other contracts for deliveries at active market locations.
Level 3.  Level 3 of the fair value hierarchy consists of assets or liabilities that are valued using significant unobservable inputs at the reporting date. These unobservable assumptions reflect our assumptions about estimates that market participants would use in pricing the asset or liability, including natural gas basis prices and annualized volatilities of natural gas prices. A significant change to any one of these inputs in isolation could result in a significant upward or downward fluctuation in the fair value measurement. These inputs may be used with industry standard valuation methodologies that result in our best estimate of fair value for the assets or liabilities at the reporting date.
Our Commodity and Market Risk (C&MR) Group determines the valuation policies and procedures. The C&MR Group reports to AltaGas’ Vice President of Commodity Risk. In accordance with Washington Gas valuation policy, we may utilize a variety of valuation methodologies to determine the fair value of Level 3 derivative contracts, including internally developed valuation inputs and pricing models. The prices used in our valuations are corroborated using multiple pricing sources, and we periodically conduct assessments to determine whether each valuation model is appropriate for its intended purpose. The C&MR Group also evaluates changes in fair value measurements on a daily basis.
At September 30, 2019 and December 31, 2018, Level 3 derivative assets and liabilities included: (i) physical contracts valued at illiquid market locations with no observable market data; (ii) long-dated positions where observable pricing is not available over the majority of the life of the contract; (iii) contracts valued using historical spot price volatility assumptions and (iv) valuations using indicative broker quotes for inactive market locations.
Our level 2 and level 3 derivatives are recorded on the balance sheets at fair value on a recurring basis.

Other financial instruments including commercial paper, unsecured notes, and other long-term receivables are recorded on the balance sheets at amortized cost. The fair value of the long-term receivable from one of our trading partners related to the Antero contract approximates its carrying value using Level 2 input to estimate the credit loss associated with the receivable. The carrying cost of our commercial paper approximates fair value using Level 2 inputs. The fair value of Washington Gas unsecured notes was estimated based on valuation techniques using indirectly observable inputs corroborated with market data and therefore is classified as Level 2.

A financial instrument’s classification within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy.

 Transfers between different levels of the fair value hierarchy may occur based on fluctuations in the valuation inputs and on the level of observable inputs used to value the instruments from period to period. It is our policy to show both transfers into and out of the different levels of the fair value hierarchy at the fair value as of the beginning of the period. Transfers out of Level 3 during the three and nine months ended September 30, 2019 and 2018 were due to valuations that experienced an increase in observable market inputs. Transfers into Level 3 during the three and nine months ended September 30, 2019 and 2018 were due to an increase in unobservable market inputs, primarily pricing points. All amounts recorded to income are from the utility cost of gas.
The following table below sets forthpresents the line items on the statements of operationsunrealized gains (losses) attributable to which amounts are recorded for the three and nine months ended September 30, 2019 and 2018, respectively, related toLevel 3 derivative instruments measured at fair value measurements using significant Level 3 inputs.on a recurring basis.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
INTRODUCTIONIntroduction
This Management’s Discussion and Analysis of Financial Condition and Results of Operations (Management’s Discussion and Analysis) analyzes the financial condition, results of operations and cash flows of Washington Gas. This discussion follows the format permitted in accordance with General Instruction H(2) of Form 10-Q, in light of Washington Gas’ status as a wholly owned subsidiary of AltaGas as permitted under General Instruction H(1) of Form 10-Q. It also includes management’s narrative analysis of results of operations and reasons for material changes. This narrative discusses past financial results and potential factors that may affect future results, potential future risks and approaches that may be used to manage them. Except where the content clearly indicates otherwise, “Washington Gas,” “we,” “us,” “our” or the “Company,”"Company" refers to Washington Gas Light Company.
Management’s Discussion and Analysis is designed to provide an understanding of our operations and financial performance and should be read in conjunction with the Company’scompany’s financial statements and the Notes to Condensed Financial StatementsStatements.
COVID-19
On March 11, 2020, the World Health Organization declared the outbreak of a strain of novel coronavirus disease, COVID-19, a global pandemic. Governments in affected areas in which we operate have imposed a number of measures designed to contain the outbreak, including business closures, travel restrictions, quarantines and cancellations of gatherings and events. Washington Gas activated a pandemic response team to monitor COVID-19 developments closely. The pandemic response team has led Company efforts to mitigate the impacts to our business, and has implemented pandemic and business continuity plans to protect our employees, customers and communities. To date, Washington Gas has been able to respond to pandemic-related challenges with minimal disruption to its operations and business and it has not experienced unavailability of a significant portion of its personnel as a result of COVID-19.
As a result of regulatory orders, we have temporarily suspended customer disconnections for non-payment, temporarily suspended collection activities, and temporarily waived assessing and billing late payment fees. We resumed assessing late payment fees in Maryland in October 2020 following a regulatory order. The suspension of collection activities has caused our overall accounts receivable portfolio to age more than historical levels. However, we do not expect the increase in credit losses to have a significant impact on net income. The PSC of DC, PSC of MD, and SCC of VA each have issued an Order authorizing Washington Gas to establish a regulatory asset to capture and track the incremental COVID-19 related costs, including incremental credit losses, which allows for assessment of recovery of those costs in future base rate cases. As of September 30, 2020, we have recorded $9.0 million of incremental COVID-19 related costs to regulatory assets across all three jurisdictions, primarily bad debt expense, and services and supplies. Additionally, we waived late payment fees of $1.6 million and $4.4 million for the three and nine months ended September 30, 2020, respectively.
No material impairments of our long-lived assets were recorded through the date of this quarterly report, as well as Washington Gas’ Form 10-KTno triggering events or changes in circumstances had occurred.
Unfavorable economic conditions due to COVID-19 have reduced demand for natural gas. Compared to prior period, the lower commercial usage in DC and VA, waived late fees, and lower service initiation fees have resulted in a decrease to net revenue. Based on the year to date results and our current estimates of COVID-19 impacts, and assuming normal weather for the period ending December 31, 2018. Our operations are seasonal and, accordingly, our operating results for the periods presented are not indicativeremainder of the year, Washington Gas expects lower commercial usage due to COVID-19 that could negatively impact our financial results. However, due to significant uncertainty related to the pandemic and its economic impact, management's judgment and estimates regarding the situation could change in the future, and current expected outcomes and actual results may differ.

The $51.9 million increase in net income was mainly from an increase in net revenues driven by the impact of rate cases, accelerated pipe replacement programs and our asset optimization program, partially offset by negative impacts from warmer weather and the COVID-19 pandemic.
Our chief operating decision maker utilizes earnings before interest, tax, depreciationthe non-GAAP measure, Earnings Before Interest, Taxes, Depreciation and amortizationAmortization (EBITDA), as the primary measure of profit and loss in assessing the results of operations. EBITDA includes operating income and other income (expense). We believe that our use of EBITDA enhances the ability to evaluate Washington Gas’Gas' performance because it excludes interest and income tax expense, which are affected by corporate-wide strategies of AltaGas such as capital financing and tax sharing allocations.financing. It also excludes depreciation and amortization which do not affect cash flow.flows.

Net RevenuesOperating revenues decreased by $58.1 million in the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019 mainly driven by the reduction in gas costs, effects of weather and consumption patterns and a negative impact from the COVID-19 pandemic, partially offset by the impact from rate cases.
We also utilize the non-GAAP measure of net revenues, calculated as revenues less the associated cost of energy and applicable revenue taxes, to assist in the analysis of profitability. The cost of the natural gas commodity (as adjusted for Asset Optimization sharing) and revenue taxes are included in the rates that Washington Gas charges to customers as reflected in operating revenues. Accordingly, changes in the cost of gas and revenue taxes associated with sales made to customers generally have no direct effect on utility net revenues, operating income or net income. Net revenues should not be considered an alternative to, or a more meaningful indicator of our operating performance than operating revenues. Additionally, net revenues may not be comparable to similarly titled measures of other companies.

Accelerated replacement programs Approved
The $3.0 million and $8.8 million increase for the three months and nine months ended September 30, 2020 compared to the same periods of the prior year were due to approved accelerated replacement programs arethat were in place with an associated surcharge mechanism to recover the cost, including a return, on those capital investments.
Impact of rate cases — The decrease in net revenues primarily reflects the impact of the HE’s report regarding the Company’s pending Virginia rate case. The report recommends a shorter amortization period of both excess deferred taxes and revenues collected based on the previous federal tax rate. The report also recommends no increase to base rates, and accordingly net revenues reflect a higher reserve recorded against new base rates put in effect January 1, 2019. Refer to “Rates and Regulatory Matters” for further discussion of these matters.
Asset optimization — We recorded a net loss of $1.3
$6.3 million including an unrealized loss of $6.5and $11.4 million increase for the three months and nine months ended September 30, 2020 compared to the same periods prior year associated with our energy-related derivativesderivatives. Refer to Note 12-Derivatives for detail discussion.
Estimated effects of weather and consumption patterns
In the District of Columbia, where Washington Gas does not have a billing mechanism to offset the effects of weather on revenues, the comparatively warmer weather primarily caused the variance to net revenues. Natural gas consumption patterns may be affected by shifts in weather patterns and non-weather-related factors such as customer conservation.
Net revenue for the quarterthree months ended September 30, 2019,2020 was negatively impacted by lower commercial usage in DC and VA due to COVID-19, resulting in a total decrease in net revenue of $2.0 million, compared to a net gain of $7.7 million including an unrealized gain of $3.3 millionthe same period 2019.
Weather was 14.7% and 10.5% warmer than normal for the quarternine months ended September 30, 2018. When these derivatives settle, any unrealized amounts will ultimately reverse2020 and Washington Gas expects to realize margins2019, respectively, with an additional negative impact from lower commercial usage in combination with related transactions that these derivatives economically hedge. The large swings in the valuations are partiallyDC and VA due to movements in unobservable inputs used in the valuationCOVID-19, driving lower net revenues of long-dated forward contracts. We believe that these values are not reflective of our ultimate cash flows as these purchases are utilized in the optimization of our long-term natural gas transportation and storage capacity resources, the value of which is not reflected at fair value.

Accelerated replacement programs — Approved accelerated replacement programs are in place with an associated surcharge mechanism to recover the cost, including a return, on those capital investments.
Customer growth — Average active customer meters increased by approximately 13,000 at the nine months ended September 30, 2019, over the number of average active customer meters at the end of the same period of 2018. Washington Gas added 8,290 and 8,759 new customers in the nine months ended September 30, 2019 and 2018, respectively, supported by additional capital and rate base. Adding new customers directly drives earnings growth through additional distribution revenues.

Interruptible revenue (net of sharing) — The increase in Interruptible revenue, net of sharing, is due to higher rates in Maryland and lower margin sharing in District of Columbia.
Asset optimization — We recorded a net gain of $8.3 million including an unrealized gain of $0.1 million associated with our energy-related derivatives for the nine months ended September 30, 2019, compared to a net gain of $28.5 million including an unrealized gain of $11.8 million for the nine months ended September 30, 2018.
Loss related to Antero Contractunder Asset optimization— We recorded the net pre-tax loss of $3.0 million in “Utility cost of gas” on the statements of operations for the nine months ended September 30, 2019 due to the litigation related to the Antero Contract. Refer to Note 10 - Commitments and Contingency for further discussion.
Impact of rate cases — The decrease in net revenues primarily reflects the impact of the HE’s report regarding the Company’s pending Virginia rate case. The report recommends a shorter amortization period of both excess deferred taxes and revenues collected based on the previous federal tax rate, as well as no incremental base revenues. Partially offsetting these adjustments are new base rates in Maryland, effective December 2018. Refer to “Rates and Regulatory Matters” for further discussion of these matters.

Gas Service to Firm Customers
The volume of gas delivered to firm customers is highly sensitive to weather variability as a large portion of the natural gas delivered by Washington Gas is used for space heating. Washington Gas’ rates are established based on an assumption of normal weather. The tariffs in the Maryland and Virginia jurisdictions include provisions that consider the effects of the RNA and the WNA/CRA mechanisms, respectively, that are designed to, among other things, eliminatemitigate the effects of weather variationseffect on net revenues.revenues of variations in weather from normal levels (refer to the section entitled Weather Risk“Weather Risk” in the Form 10-K for year ended December 31, 2019 for a further discussion of these mechanisms and other weather-related instruments included in our weather protection strategy)discussion).
Gas Service to Interruptible Customers
Washington Gas may curtail or interruptCustomers whose service can be temporarily interrupted in order for the regulated utility to this classmeet the needs of customer when the demand by firm customers exceeds specified levels.pay a lower delivery rate than firm customers and they must be able to readily substitute an alternate fuel for natural gas. Per approved tariffs, Washington Gas retains a majority of the margins earned on interruptible gas and delivery sales. Washington Gas has sharing mechanisms in all three jurisdictions where itthe District of Columbia that shares a portionmost of interruptiblethese margins with firm customers.
Gas Service for Electric Generation
Washington Gas delivers natural gas for use at two electric generation facilities in Maryland that are each owned by independent companies. Washington Gas shares with firm customers a significant majority of the margins earned from natural gas deliveries to these customers. Therefore, changes in the volume of interruptible gas deliveries to these customers do not materially affect either net revenues or net income.
LIQUIDITY AND CAPITAL RESOURCESLiquidity and Capital Resources
General Factors Affecting Liquidity
Washington Gas generally meets its liquidity and capital needs through cash on hand, retained earnings, the issuance of commercial paper and long-term debt, and equity infusionscontributions from its parent holding companies, routed through Wrangler.Wrangler SPE. Access to short-term debt markets is necessary forprovides funding to our short-term liquidity requirements, the most significant of which include buying natural gas and pipeline capacity, and financing both accounts receivable and storage gas inventory. We have accessed long-term capital markets primarily to fund capital expenditures and retire matured long-term debt.
Our ability to access debt capital markets depends on our credit ratings, general market liquidity, and demand for our credit securities. In addition, under Under the Merger commitments agreed to by AltaGas and Washington Gas, during the Merger andincluding other rules imposed by regulatory commissions or state laws in Washington Gas’ service territory, the Company is prohibited and/or restricted in its ability to make advances or issue loans to an affiliate or parent holding company without prior regulatory commission approval.

Our credit ratings depend largely on our financial performance and the ratings of our parent companies, WGL and AltaGas. A ratings downgrade could both increase our borrowing costs and trigger the need for us to post additional collateral with our wholesale counterparties or other creditors. Further, a negative change in WGL’s or AltaGas’ ratings outlook or any downgrade in their credit ratings could negatively impact our ratings outlook or downgrade our credit ratings. Such downgrades could limit our access to the credit markets and increase the costs of borrowing under available credit lines. Washington Gas has ring fencing measures in place that were further expanded during the Merger regulatory approval process. The ring-fencing measures financially separate Washington Gas from WGL, AltaGas and its non-utility affiliates as a way to protect consumers of regulated utility services from financial instability or bankruptcy that may be experienced by its parent or affiliates.
On September 13, 2019, Washington Gas issued an aggregate principal amount of $300 million and 3.65% fixed interest rate, medium-term notes that are due in September 2049. The proceeds from these notes will be used for general corporate purposes, including the retirement of short-term debt and $50 million long-term debt due in November 2019, capital expenditures, acquisition of property and working capital needs.
As of September 30, 2019, total consolidated capitalization, including current maturities of long-term debt and notes payable and project financing, comprised 50.2% common equity, 0.9% preferred stock and 48.9% long and short-term debt. This capitalization ratio varies during the year primarily due to the seasonal nature of Washington Gas’ business. See discussion regarding seasonal impacts on working capital in Short-Term Cash Requirements and Related Financing below.
Our plans provide for sufficient liquidity to satisfy our financial obligations. Generally, pursuant to its Merger commitments, Washington Gas can make dividend payments in the ordinary course of business unless any of the following regulatory limitations apply: (i) Washington Gas will not pay extraordinary dividends to its parent for three years from the date of the Merger close, (ii) Washington Gas will not pay dividends to its parent company if Washington Gas’ senior unsecured debt rating is below investment grade or (iii) Washington Gas will not make a dividend payment to its parent company if the payment would result in its equity level to drop below 48%. At September 30, 2019,2020, we had no significant restrictions on our cash balances or retained earnings that would affect the payment of dividends.
During the first and third quarter of 2020, Washington Gas received a $125.0 million and $50.0 million cash capital contribution from Wrangler SPE, respectively. The proceeds are used to support the Company's construction program, to repay its short-term debt and for other corporate purposes.
As of September 30, 2020, we believe that our cash flows from operations and sources of funding will provide sufficient liquidity to satisfy our financial obligations. However, as the impact of the COVID-19 pandemic on the economy and operations evolves, we will continue to assess our liquidity needs, the ability to access capital markets for commercial paper or long-term debt financing, and potential impacts due to the ability of our customers to pay for services. Should the Company’s cash flow be materially impacted owing to virus-driven circumstances, the Company may find itself without adequate cash flow to fund its operations, and we may need additional liquidity.
Short-Term Cash Requirements and Related Financing
Washington Gas has seasonal short-term cash requirements to fund the purchase of storage gas inventory in advance of the winter heating season. At September 30, 2019 and December 31, 2018, Washington Gas had balances in gas storage of $92.5 million and $103.9 million, respectively. Washington GasThe Company collects the cost of gas under cost recovery mechanisms approved by itsour regulators. Additionally, Washington Gas may be required to post cash collateral for certain purchases. Washington Gas is also subject to the collateral requirements of its counterparties. At September 30, 2019, Washington Gas was not required to post any cash collateral to counterparties.
In the first and fourth quarters of each calendar year, Washington Gas’ large sales volumes cause its cash requirements to peak when combined storage inventory, accounts receivable, and unbilled revenues are at their highest levels. In the second and third quarters of each calendar year, after the heating season, Washington Gas typically experiences a seasonal net loss due to reduced demand for natural gas. During this period, large amounts of Washington Gas’ current assets are converted to cash, which cash.

Variations in the timing of customer collections under Washington Gas’ gas cost recovery mechanisms can significantly affect its short-term cash requirements. At September 30, 2019 and December 31, 2018, Washington Gas had $5.0 million and $2.2 million in net under-collections from customers, respectively, reflected in current assets as gas costs due from customers. Amounts under-collected or over-collected from customers during the current gas cost recovery cycle are deferred as a regulatory asset or liability on the balance sheet until September 1 of each year, at which time the accumulated amount is transferred to gas costs due from/to customers as appropriate. At September 30, 2019 and December 31, 2018, Washington Gas had a net regulatory asset of $12.4 million and $26.4 million, respectively, related to under-collections from customers related to each current gas recovery cycle.
Washington Gas uses short-term debt in the form of commercial paper or unsecured short-term bank loans to fund seasonal cash requirements. Our policy is to maintain back-up bank credit facilities in an amount equal to or greater than our expected maximum commercial paper position.
On July 19, 2019, Washington Gas entered into an amendedclassifies certain commercial paper balances as "Long-term debt" on the balance sheets based on its ability and restated senior unsecured revolving credit facility withintent to refinance these balances on a long-term basis.

To manage credit risk, Washington Gas may require certain customers and suppliers to provide deposits, including collateral from wholesale counterparties. At September 30, 2019 and December 31, 2018, the total of these deposits and collateral reported as current liabilities in “Customer deposits and advance payments” were $42.9 million and $54.4 million, respectively. The majority of these balances are customer deposits and customer credit balances. Deposits from customers may be refunded at various times throughout the year based on customer payment habits. At the same time, other customers make new deposits that cause the balance of customer deposits to remain relatively steady. There are no restrictions on Washington Gas’ use of these customer deposits. Washington Gas pays interest to its customers on these deposits in accordance with the requirements of its regulatory commissions. In addition, customers may have credit balances due to budget credits, over payments and Company provided credits. Budget credits, which is the most frequent type of credit, occurs only for customers on the budget bill program and happens normally in the warmer months when customers’ actual bill is less than the budget bill amount. Refer to the section entitled “Credit Risk” for further discussion of our management of credit risk.
Project Financing
Washington Gas previously obtained third-party project financing on behalf of the federal government to provide funds during the construction of certain energy management services projects entered into under Washington Gas’ area-wide contract. The construction work is performed by WGL Energy Systems on behalf of Washington Gas. Washington Gas recorded a contract asset in “Unbilled revenues” representing the government’s obligation to remit principal and interest and financing obligation in “Notes payable and project financing”.
As of September 30, 2019, Washington Gas had no energy management services projects that were financed through Washington Gas and not yet complete. As of December 31, 2018, Washington Gas had $69.7 million in “Unbilled revenues” on the condensed balance sheet and$15.5 million in “Notes payable and project financing,” for energy management services projects that were financed through Washington Gas and not yet complete.
See Note 5-Short-Term Debt of the Notes to Condensed Financial Statements for a further discussion of project financing.
Long-Term Cash Requirements and Related Financing
The primary drivers of our long-term cash requirements are capital expenditures and long-term debt maturities. Our capital expenditures primarily relate to adding new utility customers and system supply and maintaining the safety and reliability of Washington Gas’ distribution system.
Security Ratings
The table below reflects the current credit ratings for the outstanding debt instruments of Washington Gas.

Additionally, failure to pay principal or interest on any other indebtedness may be deemed a default under our credit agreements. A default, if not remedied, may lead to a suspension of further loans and/or acceleration in which obligations becomebecoming immediately due and payable. In addition, certain of the credit facilities of Washington Gas contain cross-default provisions.provisions, that would declare Washington Gas in default on its credit facility if it were to default on certain of its other indebtedness.

For certain of Washington Gas’ natural gas purchase and pipeline capacity agreements, the counterparty may withhold service or deliveries or may require additional credit support if the long-term debt of Washington Gas is downgraded below the lower of a BBB- rating by Standard & Poor’s or a Baa3 rating by Moody’s Investors Service, or if Washington Gas is deemed by a counterparty not to be creditworthy. For certain other agreements, the counterparty may require additional credit support if the counterparty’s credit exposure to Washington Gas exceeds a contractually defined threshold amount, or if Washington Gas’ credit rating declines by a certain rating level. Based on its current credit ratings, Washington Gas would not be required to provide additional credit support to its counterparties for these agreements if its long-term credit rating was to be downgraded by one rating level.

Cash Flows FromProvided by Operating Activities
Washington Gas’Gas' cash flows from operating activities principally reflect gas sales and deliveries and the cost of operations. The volume of gas sales and deliveries is dependent primarily on factors external to the utility, such as growth of customer demand, weather, market prices for energy, economic conditions and measures that promote energy efficiency. Unbilled revenue and weather normalization, ratemaking adjustments and decoupling mechanisms in place, changes in delivery volumes from levels assumed when rates were approved may affect the timing of cash flows but not net income. The price at which the utility provides energy to customers is determined in accordance with regulatory-approved tariffs. In general, changes in the utility’s cost of gas may affect the timing of cash flows but not net income because the costs are recovered in accordance with rate agreements. In addition, Washington Gas’ cash flow is impacted by the timing of derivative settlements.
Net income is the result of cash and non-cash (or accrual) transactions. Only cash transactions affect Washington Gas’ cash flows from operating activities. Principal non-cash charges include depreciation, accrued or deferred pension and other post-retirement benefit costs and deferred income tax expense. Non-cash charges or credits may also be accrued under the revenue decoupling and cost reconciliation mechanisms in the utilities’ rate plans.
Net cashCash flows provided by operating activities for nine months ended September 30, 2019 was $254.1 million compared to net cash provided by operating activities of $150.8were $262.7 million for the nine months ended September 30, 2018. The increase in cash flows provided by operating activities was primarily driven by cash payment of merger commitments and related expenses in the prior period.
Cash Flows From Financing Activities
Cash flows provided by financing activities for the nine months ended September 30, 2019 totaled $41.5 million2020, compared to $221.9$254.1 million for the nine months ended September 30, 20182019. The increase was mainly due to increased payments of short-term debts.driven by decreased cash collateral posted with counterparties associated with our derivative asset and liabilities.
In September 2019, Washington Gas issued $300 million medium-term note to fund its general corporate needs. For the nine months ended September 30, 2018, Washington Gas received $303 million capital infusion from its parent company.

For financial statement impact from Antero Contract, Refer to Note 10- Commitments and Contingencies of the Notes to Condensed Financial Statements.
CREDIT RISK
Wholesale Credit Risk
Washington Gas enters into transactions with wholesale counterparties for the purpose of meeting firm ratepayer commitments, to optimize the value of its long-term capacity assets, and for hedging natural gas costs. Certain wholesale suppliers that sell natural gas to Washington Gas may have relatively low credit ratings or may not be rated by major credit rating agencies. In the event of a counterparty’s failure to deliver contracted volumes of gas or fulfill its payment obligations, Washington Gas may incur losses that would typically be passed through to its sales customers under the purchased gas cost adjustment mechanisms; however, Washington Gas may be at risk for financial loss to the extent these losses are not passed through to its customers.
Washington Gas operates under an existing wholesale counterparty credit policy that is designed to mitigate credit risks through requirements for credit enhancements including, but not limited to, letters of credit, parent guarantees and cash collateral when deemed necessary. In accordance with this policy, Washington Gas has obtained credit enhancements from certain of its counterparties. If certain counterparties or their guarantors meet the policy’s creditworthiness criteria, Washington Gas may grant unsecured credit to those counterparties or their guarantors. The creditworthiness of all counterparties is continuously monitored.
The following table provides information on our credit exposure, net of collateral, to wholesale counterparties as of September 30, 2019.

Retail Credit Risk
Washington Gas is at risk of non-payment of utility bills by customers. To manage this customer credit risk, Washington Gas may require cash deposits from high risk customers to cover payment of their bills until the requirements for the deposit refunds are met. In addition, Washington Gas has a POR program in Maryland and the District of Columbia, whereby it purchases receivables from participating energy marketers at approved discount rates. Under the program, Washington Gas is exposed to the risk of non-payment by the retail customers for these receivables. This risk is factored into the approved discount rate at which Washington Gas purchases the receivables. Base rates include a provision for recovery of uncollectible accounts based on historical levels of charge offs of accounts receivable. Washington Gas also has a provision in its Gas Administrative Charge mechanism that includes an allowance for commodity amounts included in uncollectible accounts.
MARKET RISK
We are exposed to various forms of market risk including commodity price risk, weather risk and interest-rate risk. The following discussion describes these risks and our management of them.
Price Risk
In addition, Washington Gas faces pricehas a POR program in Maryland and the District of Columbia, whereby it purchases receivables from participating energy marketers at approved discount rates, which incorporates the risk associated withof non-payment by the purchase and saleretail customers for these receivables.
COVID-19 has created widespread challenges in the job market that have resulted in increased unemployment rates, which could impact the ability of natural gas.the Company’s customers to pay for services. To assist the communities it serves, Washington Gas generally recovers the cost of the natural gas to serve customers through gas cost recovery mechanisms as approvedhas temporarily suspended customer disconnections for non-payment, temporarily suspended collection activities and temporarily waived assessing and billing late payment fees. We resumed assessing late payment fees in jurisdictional tariffs; therefore, a changeMaryland in the price of natural gas generally has no direct effect on Washington Gas’ net income. However, Washington Gas is responsible for following competitive and reasonable practices in purchasing natural gas for its customers.October 2020.
To manage price risk associated with its natural gas supply to its firm customers, Washington Gas: (i) actively manages its gas supply portfolio to balance sales and delivery obligations; (ii) injects natural gas into storage during the summer months when prices are generally lower, and withdraws that gas during the winter heating season when prices are generally higher and (iii) enters into hedging contracts and other contracts that may qualify as derivative instruments related to the sale and purchase of natural gas.
Washington Gas executes commodity-related physical and financial contracts in the form of forward, futures and option contracts as part of an asset optimization program that is managed by its internal staff. Under this program, Washington Gas realizes value from its long-term natural gas transportation and storage capacity resources when they are not being fully used to serve utility customers. Regulatory sharing mechanisms in all three jurisdictions allow the profit from these transactions to be shared between Washington Gas’ customers and shareholders.

Weather Risk
We are exposed to various forms of weather risk. Washington Gas’ operations are seasonal, with a significant portion of its revenues derived from the delivery of natural gas to residential and commercial heating customers during the winter heating season. Weather conditions directly influence the volume of natural gas delivered by Washington Gas. Weather patterns tend to be more volatile during “shoulder” months within our calendar year in which Washington Gas is going into or coming out of the primary portion of its winter heating season. During the shoulder months within quarters ending June 30 (particularly in April and May) and December 31 (particularly in October and November), customer heating usage may not highly correlate with historical levels or with the level of heating degree days that occur, particularly when weather patterns experienced are not consistently cold or warm.
Washington Gas does not have a weather related instrument or billing adjustment mechanism in the District of Columbia and as a result, its revenues are volume driven and current rates are based upon an assumption of normal weather. Without weather protection strategies, variations from normal weather will cause our earnings to increase or decrease depending on the weather pattern.
Billing Adjustment Mechanisms. In Maryland, Washington Gas has an RNA billing mechanism that is designed to stabilize the level of net revenues collected from Maryland customers by eliminating the effect of deviations in customer usage caused by variations in weather from normal levels and other factors such as conservation. In Virginia, Washington Gas has a WNA billing adjustment mechanism that is designed to eliminate the effect of variations in weather from normal levels on utility net

Item 2-Management’s Discussion and Analysis of
Financial Condition and Results of Operations (continued)


revenues for residential, commercial and industrial and group metered apartment customers. Additionally, in Virginia, as part of the CARE plan, Washington Gas has a CRA mechanism that eliminates the effect of conservation for residential customers.
For the RNA, WNA and CRA mechanisms, periods of colder-than-normal weather generally would cause Washington Gas to record a reduction to its revenues and establish a refund liability to customers, while the opposite would generally result during periods of warmer-than-normal weather. However, factors such as volatile weather patterns and customer conservation may cause the RNA and the CRA mechanisms to function conversely because they adjust billed revenues to provide a designed level of net revenue per meter.
Interest-Rate Risk
We are exposed to interest-rate risk associated with our short-term and long-term financing. Washington Gas has previously utilized derivative instruments in order to reduce its exposure to the risk of interest-rate volatility, with resulting gains and losses typically being recovered through each jurisdiction’s overall allowed rate of return.
Short-Term Debt. At September 30, 2019 and December 31, 2018, Washington Gas had outstanding notes payable, including commercial paper and project financing of $117.0 million, and $311.5 million, respectively. The carrying amount of our short-term debt approximates fair value. A change of 100 basis points in the underlying average interest rate for our commercial paper would have caused a change in interest expense of approximately $2.2 million.
Long-Term Debt. At September 30, 2019 and December 31, 2018, Washington Gas had outstanding fixed-rate MTNs and other long-term debt of $1,331.1 million and $1,035.0 million, respectively, excluding current maturities. As of September 30, 2019, the fair value of Washington Gas’ fixed-rate debt was $1,501.5 million. Our sensitivity analysis indicates that fair value would increase by approximately $77.4 million or decrease by approximately $71.8 million if interest rates were to decline or increase by 10%, respectively, from current market levels. In general, such an increase or decrease in fair value would impact earnings and cash flows only if Washington Gas were to reacquire some or all of these instruments in the open market prior to their maturity.
A total of $1,202.5 million, or approximately 89.3% of the face amount of Washington Gas’ outstanding long-term debt, excluding current maturities, have make-whole call options which would require us to pay a premium over the face amount if we were to exercise them.
 Refer to Note 11-Derivatives of the Notes to Condensed Financial Statements for a further discussion of our interest-rate risk management activity.
RATES AND REGULATORY MATTERSRegulatory Matters
Washington Gas makes its requests to modify existing rates based on its determination of the level of net investment in plant and equipment, operating expenses, and a level of return on invested capital that is just and reasonable. The following is an update of significant current regulatory matters in Washington Gas’Gas' jurisdictions.

On January 10, 2019,13, 2020, Washington Gas filed an application for rehearingauthority to increase charges for gas service in the District of Columbia. The requested rates are designed to collect approximately $35.2 million in total annual revenues. Of the requested revenue increase, $9.1 million represents costs currently collected through the PROJECTpipes surcharge; therefore, the incremental amount of the base rate increase is approximately $26.1 million. A procedural schedule was established with hearings scheduled for November 2020. The Company expects new rates to be implemented in the late first quarter or early second quarter of 2021.
Maryland Jurisdiction
Maryland 2020 Rate Case. On August 28, 2020, the company filed a rate increase application in Maryland. The requested rates are designed to collect approximately $28.4 million in total annual revenues requesting a 10.45% rate of return on equity. Of the requested revenue increase, $5.8 million represents costs currently collected through the STRIDE surcharge; therefore, the incremental amount of the base rate increase is approximately $22.6 million. On August 31, 2020 the PSC of MD alleging two errorsdocketed the application and assigned the case to the Public Utility Law Judge (PULJ) division. On September 28, 2020 the PULJ division held a prehearing conference and established a procedural schedule which anticipates a final decision on or about March 26, 2021. The Company expects new rates to be implemented in the agency’s final order.

In addition, WGL requested interim authority to provide specific services to SEMCO and AltaGas, pending Commission review of the application. On June 27, 2019 the SCC of VA issued a final order approving the revised service agreement and the new affiliate agreement (“service agreements”). The service agreements are limited to five years from the date of the order. Additionally, the service agreements are subject to certain administrative requirements which Washington Gas did not oppose. On September 25, 2019 as directed by the SCC of VA, Washington Gas submitted signed and executed copies of the agreements between SEMCO and AltaGas.
Virginia Rate Case - 2018. On July 31, 2018, Washington Gas filed an application with the SCC of VA to increase its base rates for natural gas service by $37.6 million, which includes $14.7 million of revenue associated with natural gas pipeline replacement initiatives previously approved by the SCC of VA and paid by customers through a monthly rider. Additionally, the requested revenue increase incorporated the effects of The Tax Act. Interim rates became effective, subject to refund, for usage in the January 2019 billing cycle. On April 12, 2019, Washington Gas filed rebuttal testimony and revised its original return on equity down from 10.6% to 10.3% and its overall rate of return down from 7.94% to 7.81%.

gulatoryMaryland. On March 16, 2020, the Governor of MD issued an Executive Order which ordered regulated utilities to cease disconnections and billing of late fees for residential customers through May 1, 2020, which was subsequently amended to extend the order through August 31, 2020. On September 22, 2020, the PSC of MD took an action that had the effect of extending the moratorium on service disconnections through November 15, 2020. Due to the winter moratorium on disconnections (November 1 to March 31), this has the effect of delaying residential terminations until April 1, 2021. On April 9, 2020, the PSC of MD issued an order and authorized each utility company to establish a regulatory asset to record the effects of incremental collection and other costs related to flowthrough income taxesCOVID-19 prudently incurred beginning on March 16, 2020. On August 27 and 28, 2020 the PSC of MD held Public Conference (PC) 53 to review the impact of the Executive Order on utilities and the service they provide. On August 31, 2020 the PSC of MD issued an order directing that (1) Utilities may not engage in service terminations and or charge late fees until October 1, 2020 and any notices of termination for residential accounts sent before October 1, 2020 are invalid; (2) a Public Service Company must give notice at least 45 days before terminating service on a residential account; (3) structured payment plans offered by Public Service Companies to residential customers in arrears or unable to pay must allow a minimum of 12 months to repay, with that period extending to 24 months for customers certified as low income; (4) prohibited any Public Service Company from collecting or requiring down payments or deposits as a condition of beginning a payment plan by any residential customer; and (5) prohibited any Public Service Company from refusing to negotiate or denying a payment plan to a residential customer receiving service because the company had recovered previously flowed through depreciation income tax deductions viacustomer failed to meet the SAVE rider. terms and conditions of an alternate payment plan during the past 18 months. On September 4, 2020 the PSC of MD issued a second notice in PC 53 requesting filings by Maryland’s investor-owned utilities proposing arrearage forgiveness and/or arrearage management programs. As requested by the PSC of MD, investor-owned utilities in Maryland filed a joint proposed Arrearage Management Program (AMP) plan on October 7, 2020, to be followed by a legislative-style hearing on November 9 - 10, 2020.
Virginia. On March 16, 2020, the SCC of VA issued an order which prohibited disconnections of electricity, gas, water and sewer utility services during the coronavirus public health emergency, and established certain consumer protection measures. While the SCC of VA order was extended, the disconnection order, but not the consumer protections expired on October 5, 2020. However, following the expiration of the disconnection order, the Virginia General assembly, on October 16, 2020, approved legislation that would extend the disconnection prohibition for residential customers for non-payment of bills or fees until the Governor determines the prohibition does not need to remain in place or until at least 60 days after the state of emergency declared March 12, 2020 expires, whichever is sooner. The legislation also codified the consumer protection plans, requiring utilities to offer customers in arrears fee-free repayment plans without deposit or eligibility requirements. Though not yet effective at the time of publication of this Form 10-Q, the legislation is expected to take effect following the Assembly’s consideration of any gubernatorial amendments in November. On April 29, 2020, the SCC of VA issued an order approving a request from Washington Gas and other Virginia utilities to create a regulatory asset to record incremental prudently incurred costs and suspended late payment fees attributable to the COVID-19 pandemic. The October 16, 2020 legislation approved by the general assembly established certain reporting requirements for utilities to report bad debt information and provides utilities with certain exemptions from such requirements based on utilities’ particular facts and circumstances.

Critical Accounting Policies
For a description of our critical accounting policies, refer to Management's Discussion and Analysis within our Form 10-K for the year ended December 31, 2019. We adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments onJanuary 1, 2020. Refer to Note 2 — Credit Losses for the accounting policy related to credit losses. In the third quarter of 2020, Washington Gas made a voluntary change in accounting principle for calculating the market-related value of assets used in the determination of net periodic pension and other post-retirement benefit plan costs. Refer to Note 1— Accounting Policies for further discussion. There were no other new critical accounting policies or changes during the nine months ended September 30, 2019, Washington Gas made the following pre-tax adjustments based on the HE’s recommendations: (i) reduced “Operating revenues-Utility” by $7.6 million to accrue additional amounts of liability subject to refund; (ii) reduced “Operating revenues-Utility” by $13.3 million associated with the revised amortization of the Tax Act liability; and (iii) wrote off $2.0 million in “Regulatory Assets - Other” and charged to “Operation and maintenance” expense. Additionally, the Company reduced income tax expense by $11.8 million related to the amortization of excess deferred income tax, and recorded $5.5 million after-tax impairment of a tax regulatory asset related to flowthrough income taxes. Reply comments on the HE’s report were filed by Washington Gas on October 21, 2019.2020.
Washington Gas filed reply comments challenging eleven recommendations contained in the HE’s report, including some of the items highlighted above, where the bases for the findings either disregard or are contrary to the substantial evidentiary record.

CRITICAL ACCOUNTING POLICIES
Preparation of financial statements and related disclosures in compliance with GAAP requires the selection and the application of appropriate technical accounting guidance to the relevant facts and circumstances of our operations, as well as our use of estimates to compile the financial statements. The application of these accounting policies involves judgment regarding estimates and projected outcomes of future events, including the likelihood of success of particular regulatory initiatives, the likelihood of realizing estimates for legal and environmental contingencies, and the probability of recovering costs and investments.
We have identified the following critical accounting policies that require our judgment and estimation, where the resulting estimates may have a material effect on the financial statements:
revenue from contracts with customers;
accounting for unbilled revenue;
accounting for regulatory operations — regulatory assets and liabilities;
accounting for income taxes;
accounting for contingencies;
accounting for derivatives;
accounting for fair value instruments;
impairment of long-lived assets; and
accounting for pension and other post-retirement benefit plans.
For a description of these critical accounting policies, refer to Management’s Discussion and Analysis within our Form 10-KT. There were no new critical accounting policies or changes to our critical accounting policies during the three month period ended September 30, 2019.

ITEM 1. LEGAL PROCEEDINGS

TheFrom time to time the Company is involved in various litigation matters arising out of the normal course of business. In particular, the nature of our business ordinarily results in periodic regulatory proceedings before various state and federal authorities. For information regarding pending federal and state regulatory matters, see Note 10-Commitments11 — Commitments and Contingencies of the Notes to Condensed Financial Statements.
Silver Spring, Maryland IncidentShow-Cause Order
On April 23, 2019, the National Transportation and Safety Board (NTSB) held a hearing during which it found, among other things, that the probable cause of the August 10, 2016, explosion and fire at an apartment complex on Arliss Street in Silver Spring, Maryland “was the failure of an indoor mercury service regulator with an unconnected vent line that allowed natural gas into the meter room where it accumulated and ignited from an unknown ignition source. Contributing to the accident was the location of the mercury service regulators where leak detection by odor was not readily available.” Washington Gas disagrees with the NTSB’s probable cause findings. Following this hearing, on June 10, 2019, the NTSB issued an accident report.
In connection with the incident, a total of 37 civil actions related to the incident have been filed and are pending against WGL and Washington Gas in the Circuit Court for Montgomery County, Maryland. All cases have been consolidated for discovery purposes. All of these suits seek unspecified damages for personal injury and/or property damage. A trial date for eight bellwether civil actions has been scheduled for December 2, 2019. In addition, two suits were recently filed related to the incident, one each in the Superior Court for the District of Columbia and one in the Circuit Court of Montgomery County, Maryland.
At this stage of the litigation, the outcome is not yet determinable and management is unable to make an estimate of any potential loss or range of potential losses that are reasonably possible of occurring. As a result, management has only recorded a reserve for a few of the actions for which a settlement offer was made. Washington Gas maintains excess liability insurance coverage from highly-rated insurers, subject to a nominal self-insured retention. Washington Gas believes that this coverage will be sufficient to cover any significant liability that may result from this incident.
In connection with the incident, onOn September 5, 2019, the PSC of MD ordered the Company within 30 days, to (i) provide a detailed response to the NTSB’s probable cause findings and (ii) provide evidence regarding the status of a 2003 mercury regulator replacement program and, if the program was not completed, to show cause why the PSC of MD should not impose a civil penalty on the Company. (Show-Cause Order).
On September 16, 2019,The Company timely responded to the PSC of MD granted the Company a 14-day extension to file its Response to theMD’s Show-Cause Order.
On October 18, 2019, the Company filed its Response to the Show-Cause Order, (i) providing a detailed response to the NTSB’s probable cause findings, and (ii) providing evidence regarding the status of aits 2003 mercury regulator replacement program and demonstrating cause why the PSC of MD should not impose a civil penalty on the Company. Following the Company’s response, certain intervenors filed written comments and a public hearing was held on the matter, with some intervenors and members of the public advocating for penalties against the Company. The Company filed its rejoinder comments and the Show-Cause Order is working its way through the regulatory proceeding process with the PSC of MD. An evidentiary hearing was conducted on September 24-25, 2020. Initial briefs were filed on October 28, 2020 and reply briefs will be filed on November 13, 2020.

Item 1A. Risk Factors
ITEM 1A. RISK FACTORS

The PSC of MD has not adopted a procedural schedule with respectCOVID-19 global health pandemic poses challenges to this matter but has indicated that it will schedule one public hearing near the apartment complex at Arliss Street.
Given the early stagehealth and safety of the Show-Cause proceeding,Company’s personnel and the strength of communities it serves. These challenges could negatively impact the Company’s cash flow and results of operations.
As the COVID-19 pandemic continues to unfold, governments in the jurisdictions in which Washington Gas operates have maintained measures designed to contain the outbreak, including business closures and restrictions, travel restrictions and border closings, quarantines and restrictions on gatherings and events. The magnitude, outcome and duration of the pandemic remains uncertain. As a result, it is not yet determinablecurrently possible to accurately quantify the total potential impact of the pandemic on Washington Gas’ operations or financial results.
We have identified the following as potential direct or indirect impacts to our business and managementoperations from the pandemic:
key employees and personnel: Although the Company has been designated an essential service provider and its essential employees and operations are exempt from government mandated closures and stay-at-home orders, our ability to keep essential operating personnel in place may be challenged as a result of COVID-19 outbreaks or quarantines. Employees who either contract or are exposed to the virus must isolate themselves from others, and combined with the health consequences of the virus, could be limited in their ability to perform key activities. Should there be a widespread inability of our workforce, or that of our contractors, to perform their duties, this would have an adverse impact on our ability to continue normal operations. In addition, unavailability of personnel could impact the Company’s ability to expand its business by decreasing construction activities and slowing the pace of the Company’s accelerated pipeline replacement programs. Also, we may face allegations of liability to the extent that we are unable to effectively protect our workforce against the transmission of the virus;
return to work: As Washington Gas reintegrates its personnel back into the workplace in response to the lifting of government stay-at-home orders, it may incur additional costs to adapt the workplace to meet applicable health and safety requirements. Shortages in PPE may require the corporation to revise or delay such reintegration plans. To the extent that it is unable to predicteffectively protect its workforce against the likelihoodtransmission of the virus, Washington Gas may face allegations of liability. Additionally, the Company must maintain flexibility in the event of new stay-at-home orders that could occur in the event infection rates increase.
adverse impacts on cash flows: COVID-19 could impact gas demand through business closures or other impacts. Additionally, widespread challenges to various businesses and to the job market as a civil penalty, result of the virus have resulted in increased business closures and unemployment rates, which could impact the ability of the Company’s customers to pay for services. Each jurisdiction in which Washington Gas serves issued mandates prohibiting suspension and/or collection activities for nonpayment of customer accounts, all of which remain in place to varying degrees. Should the Company’s cash flow be materially impacted owing to virus-driven circumstances, the Company may find itself without adequate cash flow to fund its operations;
counterparty and supplier risk: There is increased exposure that certain of our contract counterparties and suppliers could fail to meet their obligations to us. Such increased non-performance by a significant counterparty or supplier could adversely affect our operations and financial results.
privacy and cybersecurity: There has been an observed increase in volume and sophistication of targeted cyberattacks since the declaration of the global pandemic. Further, pandemic-adjusted operations, such as work from home arrangements and remote access to the company’s systems, may pose heightened risk of cybersecurity and privacy breaches.
access to capital: The uncertainty in the global financial markets could make an estimatecapital increasingly hard to access.
IT infrastructure: Pandemic-adjusted operations, such as work from home arrangements, have put additional stress on the company’s IT infrastructure as a result of anyremote access demands and online meetings. A failure of such infrastructure could severely limit the ability of the company to conduct ordinary operations.
These risks may adversely impact the Company’s ability to carry out its business plans for 2020. Washington Gas is closely monitoring developments related to COVID-19, including the existing and potential civil penalty or range of potential civil penalty.
