Notes to Condensed Consolidated Financial Statements (unaudited)


 
1.    Basis of Accounting Presentation
Our accompanying Condensed Consolidated Financial Statements (unaudited) reflect all normal recurring adjustments that are necessary, in the opinion of management, to present fairly the results of operations in accordance with GAAP in the United States of America. The accompanying financial statements contain our accounts and that of our majority-owned or controlled subsidiaries.
The accompanying financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.2018. Income for interim periods may not be indicative of results for the calendar year due to weather variations and other factors.
The Condensed Consolidated Financial Statements (unaudited) have been prepared pursuant to the rules and regulations of the SEC. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations, although we believe that the disclosures made in this quarterly reportQuarterly Report on Form 10-Q are adequate to make the information herein not misleading.
2.    Recent Accounting Pronouncements


Recently Issued Accounting Pronouncements


We are currently evaluating the impact of certain ASUs on our Condensed Consolidated Financial Statements (unaudited) and Notes to Condensed Consolidated Financial Statements (unaudited), which are described below:

ITEM 1. FINANCIAL STATEMENTS (continued)

Notes to Condensed Consolidated Financial Statements (unaudited) (continued)

StandardDescriptionEffective DateEffect on the financial statements or other significant matters
ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments
The pronouncement clarifies and improves certain areas of guidance related to the recently issued standards on credit losses, hedging, and recognition and measurement. Topics 1, 2, and 5 of this update amends ASU 2016-13 as it relates to accrued interest, transfers between investment classifications, expected recoveries and reinsurance recoverables. Topic 3 improves guidance related to fair value hedges. Topic 4 of this update relates to codification improvements to ASU 2016-01.Annual periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted.We maintain investments in U.S. Treasury, corporate and mortgage-backed debt securities, which are pledged as collateral for trust accounts related to our wholly-owned insurance company. These debt securities are classified as available for sale ("AFS"). Upon adoption of ASU 2019-04 and 2018-14, we expect to revise our impairment model for AFS debt securities by implementing an allowance approach instead of an 'other than temporary' impairment model. We have recorded balances for trade receivables that also fall within the scope of the standard. We are currently assessing our process of recording reserves for uncollectible receivables to evaluate whether significant changes to our policy will be necessary to comply with the current expected credit loss model. ASC 326 also defines additional presentation and disclosure requirements. We are currently reviewing the impact of these requirements on our disclosures related to credit in our Notes to Condensed Consolidated Financial Statements (unaudited). We are unable to reasonably estimate the quantitative impact of adoption on our Condensed Consolidated Financial Statements (unaudited). We expect to adopt this ASU on its effective date.
ASU 2016-13,  Financial Instruments-Credit Losses (Topic 326)
The pronouncement changes the impairment model for most financial assets, replacing the current "incurred loss" model. ASU 2016-13 will require the use of an "expected loss" model for instruments measured at amortized cost. It will also require entities to record allowances for available-for-sale debt securities rather than impair the carrying amount of the securities. Subsequent improvements to the estimated credit losses of available-for-sale securities will be recognized immediately in earnings instead of over time as they are under historic guidance.Annual periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for annual or interim periods beginning after December 15, 2018.We maintain investments in U.S. Treasury, corporate and mortgage-backed debt securities which are pledged as collateral for trust accounts related to our wholly-owned insurance company. These debt securities are classified as available for sale. We are currently evaluating the impact of adoption, if any, on our Condensed Consolidated Financial Statements (unaudited) and Notes to Condensed Consolidated Financial Statements (unaudited).
ASU 2018-11, Leases (Topic 842): Targeted Improvements
The pronouncement allows entities the option to initially apply ASC 842 at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption.Annual periods beginning after December 15, 2018, including interim periods therein. Early adoption is permitted.We are the lessee for substantially all of our current leasing activity. Upon adopting ASC 842 we will begin recognizing right-of-use assets and liabilities associated with operating leases (other than short term operating leases) on our Condensed Consolidated Balance Sheets (unaudited). The impact of this change on the balance sheet is not reasonably estimable at this time. We do not anticipate the adoption of ASC 842 will have a material impact to our results of operations or cash flows. We are implementing a new lease accounting system, which we will utilize to capture, track, and account for lease data. We began system testing at the end of June 2018 and anticipate full system implementation prior to the effective date of these standards. ASC 842 provides lessees the option of electing an accounting policy, by class of underlying asset, in which the lessee may choose not to separate nonlease components from lease components. We currently anticipate adopting this practical expedient for certain classes of leases. Further, we tentatively expect to elect the "practical expedient package" described in ASC 842-10-65-1. We maintain a substantial number of easements and expect the provisions of ASU 2018-01 will ease the process of implementing ASC 842. We tentatively plan to elect the transition method provided in ASU 2018-11. We intend to adopt these standards effective January 1, 2019.
ASU 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842
The pronouncement offers a practical expedient for accounting for land easements under ASU 2016-02. This practical expedient allows an entity the option of not evaluating existing land easements under ASC 842. New or modified land easements will still require evaluation under ASC 842 on a prospective basis beginning on the date of adoption.
ASU 2016-02, Leases (Topic 842)
The pronouncement introduces a lessee model that brings most leases on the balance sheet. The standard requires that lessees recognize the following for all leases (with the exception of short-term leases, as that term is defined in the standard) at the lease commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term.

StandardDescriptionEffective DateEffect on the financial statements or other significant matters
ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans
The pronouncement modifies the disclosure requirements for defined benefit pension or other postretirement benefit plans. The guidance removes disclosures that are no longer considered cost beneficial, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. The modifications affect annual period disclosures and must be applied on a retrospective basis to all periods presented.Annual periods ending after December 15, 2020. Early adoption is permitted.
We are currently evaluating the effects of this pronouncement on our Notes to Condensed Consolidated Financial Statements (unaudited). We expect to adopt this ASU on its effective date.


Recently Adopted Accounting Pronouncements
StandardAdoption
ASU 2018-02, Income Statement—Reporting Comprehensive Income2019-01, Leases (Topic 220)842): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income
We adopted this ASU effective March 31, 2018. Upon adoption, $9.5 million of tax effects that were stranded in accumulated other comprehensive loss as a result of the implementation of the TCJA were reclassified to retained deficit. This change is reflected on our Condensed Statements of Consolidated Equity (unaudited).
ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)
We adopted this ASU effective January 1, 2018. The adoption of this standard did not have a material impact on our Condensed Consolidated Financial Statements (unaudited) or Notes to Condensed Consolidated Financial Statements (unaudited).

3.    Revenue Recognition
ASC 606 Adoption. In 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606). ASU 2014-09 outlines a single, comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The core principle of the new standard is that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (ASC 606): Principal versus Agent Considerations, and ASU 2016-12, Revenue from Contracts with Customers (ASC 606): Narrow-Scope Improvements and Practical Expedients. We adopted the provisions of ASC 606 beginning on January 1, 2018 using a modified retrospective method, which was applied to all contracts. No material adjustments were made to January 1, 2018 opening balances as a result of the adoption. As required under the modified retrospective method of adoption, results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with ASC 605.

Beginning in 2018 with the adoption of ASC 606, the Condensed Statements of Consolidated Income (Loss) (unaudited) disaggregates “Customer revenues” (i.e. ASC 606 Revenues) from “Other revenues,” both of which are discussed in more detail below.
Customer Revenues. Substantially all of our revenues are tariff-based, which we have concluded is within the scope of ASC 606. Under ASC 606, the recipients of our utility service meet the definition of a customer, while the operating company tariffs represent an agreement that meets the definition of a contract. ASC 606 defines a contract as an agreement between two or more parties, in this case us and the customer, which creates enforceable rights and obligations. In order to be considered a contract, we have determined that it is probable that substantially all of the consideration to which we are entitled from customers will be collected upon satisfaction of performance obligations. We maintain common utility credit risk mitigation practices, including requiring deposits and actively pursuing collection of past due amounts. In addition, our regulated operations utilize certain regulatory mechanisms that facilitate recovery of bad debt costs within tariff-based rates, which provides further evidence of collectibility.
We have identified our performance obligations created under tariff-based sales as 1) the commodity (natural gas or electricity, which includes generation and capacity) and 2) delivery. These commodities are sold and / or delivered to and generally consumed by customers simultaneously, leading to satisfaction of our performance obligations over time as gas or electricity is delivered to customers. Due to the at-will nature of utility customers, performance obligations are limited to the services requested and received to date. Once complete, we generally maintain no additional performance obligations.
Transaction prices for each performance obligation are generally prescribed by each operating company’s respective tariff. Rates include provisions to adjust billings for fluctuations in fuel and purchased power costs and cost of natural gas. Revenues are adjusted for differences between actual costs subject to reconciliation and the amounts billed in current rates. Under or over recovered revenues related to these cost recovery mechanisms are included in regulatory assets or liabilities on the Condensed Consolidated Balance Sheets (unaudited) and are recovered from or returned to customers through adjustments to tariff rates. As we provide and deliver service to customers, revenue is recognized based on the transaction price allocated to each performance obligation. In general, revenue recognized from tariff-based sales is equivalent to the value of natural gas or electricity supplied and billed each period, in addition to an estimate for deliveries completed during the period but not yet billed to the customer.
In addition to tariff-based sales, our Gas Distribution Operations segment enters into balancing and exchange arrangements of natural gas as part of our operations and off-system sales programs. We have concluded that these sales are within the scope of ASC 606. Performance obligations for these types of sales include transportation and storage of natural gas and can be satisfied at a point in time or over a period of time, depending on the specific transaction. For those transactions that span a period of time, we record a receivable or payable for any cumulative gas imbalances, as well as for any gas inventory borrowed or lent under a Gas Distributions Operations exchange agreement.
Revenue Disaggregation and Reconciliation. We disaggregate revenue from contracts with customers based upon reportable segment as well as by customer class. As our revenues are primarily earned over a period of time and we do not earn a material amount of revenues at a point in time, revenues are not disaggregated as such below. The Gas Distribution Operations segment provides natural gas service and transportation for residential, commercial and industrial customers in Ohio, Pennsylvania, Virginia, Kentucky, Maryland, Indiana and Massachusetts. The Electric Operations segment provides electric service in 20 counties in the northern part of Indiana.

Customer Accounts Receivable. Accounts receivable on our Condensed Consolidated Balance Sheets (unaudited) includes both billed and unbilled amounts, as well as certain amounts that are not related to customer revenues. Unbilled amounts of accounts receivable relate to a portion of a customer’s consumption of gas or electricity from the date of the last cycle billing date through the last day of the month (balance sheet date). Factors taken into consideration when estimating unbilled revenue include historical usage, customer rates and weather. The opening and closing balances of customer receivables for the six months ended June 30, 20182019 are presented in the table below. We had no significant contract assets or liabilities during the period. Additionally, we have not incurred any significant costs to obtain or fulfill contracts.

Utility revenues are billed to customers monthly on a cycle basis. We generally expect that substantially all customer accounts receivable will be collected within the month following customer billing, as this revenue consists primarily of monthly, tariff-based billings for service and usage.
Other Revenues. As permitted by accounting principles generally accepted in the United States, regulated utilities have the ability to earn certain types of revenue that are outside the scope of ASC 606. These revenues primarily represent revenue earned under Alternative Revenue Programs. Alternative Revenue Programs represent regulator-approved programs that allow for the adjustment of billings and revenue for certain broad, external factors, or for additional billings if the entity achieves certain objectives, such as a specified reduction of costs. We maintain a varietycommon utility credit risk mitigation practices, including requiring deposits and actively pursuing collection of these programs, including demand side management initiativespast due amounts. In addition, our regulated operations utilize certain regulatory mechanisms that recover costs associated with the implementation of energy efficiency programs, as well as normalization programs that adjust revenues for the effects of weather or other external factors. Additionally, we maintain certain programs with future test periods that operate similarly to FERC formula rate programs and allow forfacilitate recovery of bad debt costs incurredwithin tariff-based rates, which provides further evidence of collectibility. It is probable that substantially all of the consideration to replace aging infrastructure. When the criteria to recognize Alternative Revenue have been met,which we establish a regulatory asset and present revenueare entitled from Alternative Revenue Programs on the Condensed Statementscustomers will be collected upon satisfaction of Consolidated Income (Loss) (unaudited) as “Other revenues.” When amounts previously recognized under Alternative Revenue accounting guidance are billed, we reduce the regulatory asset and record a customer account receivable.

4.    Earnings Per Share
Basic EPS is computed by dividing net income availableattributable to common shareholders by the weighted-average number of shares of common stock outstanding for the period. The weighted-average shares outstanding for diluted EPS includes the incremental effects of the various long-term incentive compensation plans. The calculation of diluted earnings per share excludesplans and forward agreements when the impact of forward agreements (seewould be dilutive (See Note 5 "Equity"), which had an anti-dilutive effect for the periods outstanding. The computation of diluted average common shares for the three months ended June 30, 2017 is not presented since we had a net loss on the Condensed Statements of Consolidated Income (Loss) (unaudited) during the period and any incremental shares would have had an anti-dilutive impact on EPS..

5.    Equity
Common Stock. As of June 30, 2019, we had 600,000,000 shares of common stock authorized for issuance, of which 373,249,295 shares were outstanding.
ATM Program and Forward Sale Agreement. On May 3, 2017,November 1, 2018, we entered into fourfive separate equity distribution agreements, pursuant to which we may sell, from time to time, up to an aggregate value of $500.0 million of our common stock. During the three and six months ended June 30, 2017, we issued 1,318,461 shares of common stock under the program at an average price of $25.88 per share, receiving proceeds, net of fees, of $33.8 million. There was no activity under the ATM program in 2018. As of June 30, 2018, the ATM program (including impacts of forward sales agreements discussed below) had approximately $10.0 million of equity available for issuance. The program expires on December 31, 2018.2020.
On November 13, 2017,December 6, 2018, under the ATM program, we executed a forward agreement, which allows us to issue a fixed number of shares at a price to be settled in the future. From November 13, 2017December 6, 2018 to December 8, 2017, 6,345,86010, 2018, 4,708,098 shares were borrowed from third parties and sold by the dealer at a weighted average price of $27.24$26.55 per share. We may settle this agreement in shares, cash, or net shares by November 12, 2018.December 6, 2019. Had we settled all 6,345,860the shares under the forward agreement at June 30, 2018,2019, we would have received approximately $169.4$123.8 million, based on a net price of $26.70$26.30 per share.
Private PlacementAs of Common Stock. On May 4, 2018,June 30, 2019, the ATM program (including impacts of the forward sale agreement discussed above) had $309.4 million of equity available for issuance. We did not have any activity under the ATM program for the three and six months ended June 30, 2019.
Preferred Stock. As of June 30, 2019, we completed the sale of 24,964,163had 20,000,000 shares of $0.01 par value commonpreferred stock at a priceauthorized for issuance, of $24.28 per share in a private placement to selected institutional and accredited investors.which 440,000 shares of preferred stock were outstanding.

The common stock issued in connection with the private placement was registered on Form S-1, filed with the SEC on May 11, 2018.
Private Placement of Preferred Stock. On June 11, 2018, we completed the sale of 400,000 shares of 5.650% Series A Fixed-Rate Reset Cumulative Redeemable Perpetual Preferred Stock (the "Series A Preferred Stock") at a price of $1,000 per share. The transaction resulted in $400.0 million of gross proceeds or $394.4 million of net proceeds, after deducting commissions and sales expenses. The Series A Preferred Stock was issued in a private placement pursuant to SEC Rule 144A. We agreed pursuant to a registration rights agreement to file with the SEC a registration statement enabling holders to exchange their unregistered shares of Series A Preferred Stock for publicly registered shares with substantially identical terms.
Proceeds from the issuance of the Series A Preferred Stock were used to pay a portion of the notes tendered in June 2018 and the redemption of the remaining notes in July 2018. See Note 15, “Long-term Debt” for additional information regarding the tender offer and redemption.
Dividends on the Series A Preferred Stock accrue and are cumulative from the date the shares of Series A Preferred Stock were originally issued to, but not including, June 15, 2023 at a rate of 5.650% per annum of the $1,000 liquidation preference per share. On and after June 15, 2023, dividends on the Series A Preferred Stock will accumulate for each five year period at a percentage of the $1,000 liquidation preference equal to the five-year U.S. Treasury Rate plus (i) in respect of each five year period commencing on or after June 15, 2023 but before June 15, 2043, a spread of 2.843% (the “Initial Margin”), and (ii) in respect of each five year period commencing on or after June 15, 2043, the Initial Margin plus 1.000%. The Series A Preferred Stock may be redeemed by us at our option on June 15, 2023, or on each date falling on the fifth anniversary thereafter, or in connection with a ratings event (as defined in the Certificate of Designation of the Series A Preferred Stock).
Holders of Series A Preferred Stock generally have no voting rights, except for limited voting rights with respect to (i) potential amendments to our certificate of incorporation that would have a material adverse effect on the existing preferences, rights, powers or duties of the Series A Preferred Stock, (ii) the creation or issuance of any security ranking on a parity with the Series A Preferred Stock if the cumulative dividends payable on then outstanding Series A Preferred Stock are in arrears, or (iii) the creation or issuance of any security ranking senior to the Series A Preferred Stock. The Series A Preferred Stock does not have a stated maturity and is not subject to mandatory redemption or any sinking fund. The Series A Preferred Stock will remain outstanding indefinitely unless repurchased or redeemed by us. Any such redemption would be effected only out of funds legally available for such purposes and will be subject to compliance with the provisions of our outstanding indebtedness.
    
In addition, 20,000 shares of Series B–1 Preferred Stock, par value $0.01 per share, were issued as a distribution with respect to the Series B Preferred Stock in order to enhance the voting rights of the Series B Preferred Stock to comply with the New York Stock Exchange’s minimum voting rights policy. Holders of Series B–1 Preferred Stock are not entitled to receive dividend payments and have no conversion rights. The Series B–1 Preferred Stock is paired with the Series B Preferred Stock and may not be transferred, redeemed or repurchased except in connection with the simultaneous transfer, redemption or repurchase of the underlying Series B Preferred Stock.

6.    Gas in Storage
We use both the LIFO inventory methodology and the weighted-average cost methodology to value natural gas in storage. Gas Distribution Operations prices natural gas storage injections at the average of the costs of natural gas supply purchased during the year. For interim periods, the difference between current projected replacement cost and the LIFO cost for quantities of gas temporarily withdrawn from storage is recorded as a temporary LIFO liquidation credit or debit within the Condensed Consolidated Balance Sheets (unaudited). Due to seasonality requirements, we expect interim variances in LIFO layers to be replenished by year end. We had a temporary LIFO liquidation debit of $12.9$12.3 million and zero as of June 30, 20182019 and December 31, 2017,2018, respectively, for certain gas distribution companies recorded within “Prepayments and other,” on the Condensed Consolidated Balance Sheets (unaudited).
7.    Asset Retirement Obligations
In the second quarter of 2018, we made revisions to the estimated costs associated with refining the CCR compliance plan. The CCR rule requires the continued collection of data over time to determine the specific compliance solution. The change in estimated costs resulted in an increase to the asset retirement obligation liability of $62.5 million that was recorded in June 2018. See Note 17-C, "Environmental Matters," for additional information on CCRs.

Certain operating costs of our distributionoperating companies are significant, recurring in nature and generally outside the control of the distributionoperating companies. Some states allow the recovery of such costs through cost tracking mechanisms. Such tracking mechanisms allow for abbreviated regulatory proceedings in order for the distributionoperating companies to implement charges and recover appropriate costs. Tracking mechanisms allow for more timely recovery of such costs as compared with more traditional cost recovery mechanisms. Examples of such mechanisms include GCR adjustment mechanisms, tax riders, and bad debt recovery mechanisms.mechanisms, electric energy efficiency programs, MISO non-fuel costs and revenues, resource capacity charges, federally-mandated costs and environmental-related costs.
A portion of the distribution companies'Gas Distribution revenue is related to the recovery of gas costs, the review and recovery of which occurs through standard regulatory proceedings. All states in our operating area require periodic review of actual gas procurement activity to determine prudence and to permit the recovery of prudently incurred costs related to the supply of gas for customers. Our distribution companies have historically been found prudent in the procurement of gas supplies to serve customers.
Certain of our distribution companies have completed rate proceedings involving infrastructure replacement or are embarking upon regulatory initiatives to replace significant portions of their operating systems that are nearing the end of their useful lives. Each LDC's approach to cost recovery may be unique, given the different laws, regulations and precedent that exist in each jurisdiction.
Columbia of Ohio. On January 10, 2018, the PUCO issued an entry to investigate the impacts of the TCJA including an invitation to utilities and other interested stakeholders to file public comments including: (1) those components of utility rates that the PUCO will need to reconcile with the TCJA; and (2) the process and mechanics for how the PUCO should do so. The PUCO also directed utilities to record a regulatory liability for the estimated reduction in federal income tax resulting from the TCJA. On February 15, 2018, Columbia of Ohio filed comments proposing to: (1) reflect the impact of the TCJA on its application to adjust rates associated with its IRP rider, subsequently filed on February 27, 2018; and (2) file a reduction in other base rates no later than October 15, 2018 reflecting the impact of the TCJA. The PUCO issued a procedural schedule on May 24, 2018 and a hearing was held on July 10, 2018.
On January 31, 2018, the PUCO approved Columbia of Ohio’s application to extend its IRP for an additional five years (2018-2022), allowing Columbia of Ohio to continue to invest and recover on its accelerated main replacements. The Office of the Ohio Consumers’ Counsel filed an application for rehearing asserting certain issues with Columbia of Ohio's application. On May 9, 2018, the PUCO issued an order denying the application for rehearing.
As referred to above, Columbia of Ohio filed its most recent application to adjust rates associated with its IRP rider on February 27, 2018, which requested authority to increase annual billings by approximately $2.3 million (net of the impact of the TCJA) reflecting recovery of and return on approximately $207 million of incremental IRP capital additions in 2017. A stipulation was filed with the PUCO on March 28, 2018. On April 25, 2018, the PUCO approved Columbia of Ohio’s annual IRP tracker adjustment with rates effective May 1, 2018.
On December 1, 2017, Columbia of Ohio filed an application that requested authority to implement a rider to begin recovering plant and associated deferrals related to its CEP. The CEP was established in 2011 and allows for deferral of interest, depreciation and property taxes on certain plant investments not recovered through its IRP modernization tracker. The application requested authority to increase annual revenues, through the requested rider, by approximately $70 million, with biennial increases up to approximately $98 million in 2022. On May 9, 2018, the PUCO appointed an independent auditor to assist the PUCO with the review of the accounting accuracy, prudency and compliance of Columbia of Ohio with its Commission-approved CEP deferrals. The audit of the CEP is expected to be completed by September 4, 2018 at which point we anticipate a full procedural schedule will be established.
NIPSCO Gas. On January 3, 2018, the IURC initiated an investigation to review and consider the possible implications of the TCJA on utility rates. The Commission ordered a two phase investigation. Phase 1 solely dealt with the prospective changes in rates to reflect the change in tax rates. In accordance with the procedural schedule, on March 26, 2018, NIPSCO filed revised gas tariffs reflecting the impact of the change in tax rate for its applicable rates and charges. The IURC approved NIPSCO's Phase 1 filing on April 26, 2018. The revised tariffs were effective May 1, 2018. The stipulation and settlement agreement filed on April 20, 2018, in NIPSCO’s gas rate case (discussed immediately below) resolved all issues in Phase 2.
On September 27, 2017, NIPSCO filed a base rate case with the IURC, seeking an annual revenue increase of $143.5 million (inclusive of amounts being recovered through various tracker programs). As part of this filing and among other items, NIPSCO proposed to update base rates for ongoing infrastructure improvements, revised depreciation rates and ongoing level of expenses to reflect the current costs of providing natural gas service. NIPSCO submitted a rebuttal on March 28, 2018 updating its request, including the impact of the TCJA, seeking a revised annual revenue increase of $138.1 million. On April 20, 2018, a settlement

agreement was filed with the IURC seeking, among other items, an annual revenue increase of $107.3 million. An order from the IURC is expected in the third quarter of 2018 with rates expected to be effective October 1, 2018 for Phase 1 implementation.
On November 8, 2017, NIPSCO filed a petition with the IURC seeking approval of NIPSCO’s federally mandated pipeline safety compliance plan. As part of the aforementioned settlement agreement filed in NIPSCO’s gas base rate case proceeding, NIPSCO and the parties to the settlement agreement settled all issues in this proceeding as well, including moving certain costs from the base rate proceeding to this pipeline safety compliance plan. The updated four year compliance plan includes a total estimated $91.5 million of capital costs and $35.5 million of expected operating and maintenance costs. NIPSCO is requesting all associated accounting and ratemaking relief, including establishment of a periodic rate adjustment mechanism. An IURC order is expected in the third quarter of 2018.
On April 30, 2013, the Governor of Indiana signed Senate Enrolled Act 560, the TDSIC statute, into law. Among other provisions, this legislation provides for cost recovery outside of a base rate proceeding for new or replacement electric and gas transmission, distribution and storage projects that a public utility undertakes for the purposes of safety, reliability, system modernization or economic development. Provisions of the TDSIC statute require that, among other things, requests for recovery include a seven-year plan of eligible investments. Once the plan is approved by the IURC, eighty percent of eligible costs can be recovered using a periodic rate adjustment mechanism. The cost recovery mechanism is referred to as a TDSIC mechanism. Recoverable costs include a return on, and of, the investment, including AFUDC, post-in-service carrying charges, operation and maintenance expenses, depreciation and property taxes. The remaining twenty percent of recoverable costs are to be deferred for future recovery in the public utility’s next general rate case. The periodic rate adjustment mechanism is capped at an annual increase of no more than two percent of total retail revenues. On April 2, 2018, NIPSCO filed a new seven-year gas TDSIC plan with the IURC beginning in 2019. The filing seeks approval of a total capital expenditure level of approximately $1.25 billion. An IURC order is expected in the fourth quarter of 2018.
On February 27, 2018, NIPSCO filed TDSIC-8 requesting to recover an incremental increase to revenue of $0.8 million (net of the impacts of TCJA) associated with incremental capital investment of $77.9 million made in the second half of 2017. An IURC order was expected in the second quarter of 2018, with new rates effective in July. On June 20, 2018, the Indiana Supreme Court issued an order reversing the IURC and the Court of Appeals in NIPSCO’s gas TDSIC-4 proceeding and held that periodic rate increases are available only for specific projects designated in the threshold proceeding and multiple-unit-projects not identified with particularity are not recoverable through the tracker. A revised TDSIC-8 was filed on July 18, 2018 and reduced the previous February 27, 2018 request by $0.2 million associated with incremental capital investment of approximately $54 million. An order on the revised filing is expected in the third quarter of 2018. In the second quarter of 2018, NIPSCO recorded a liability of $2.5 million associated with the TDSIC-4 through TDSIC-8 filings for a related passback of revenue previously billed to customers. Timing of this passback has not yet been determined.
Columbia of Massachusetts. On February 2, 2018, the Massachusetts DPU opened an investigation into the effect of the reduction in federal income tax rates on the rates charged by utility companies. Columbia of Massachusetts was directed to account for any revenues associated with the difference between previous and current income tax rates and excess deferred income taxes as regulatory liabilities effective January 1, 2018. Companies were ordered to submit a proposal to revise rates by May 1, 2018. The order indicates that if a company files a base rate case prior to the conclusion of the investigation, it must address the TCJA issues as part of the case. Since CMA filed a base rate case on April 13, 2018, the changes in base rates and the regulatory liability disposition related to the TCJA are reflected in the case. On June 29, 2018, the Massachusetts DPU required companies in a rate case to reduce rates as of July 1, 2018 or, in the alternative, defer this rate reduction to coincide with the effective date of new rates in a rate case, provided that tax savings from July 1, 2018 through the effective date of new rates accrue interest at prime rate. On July 2, 2018, Columbia of Massachusetts filed tariffs reflecting revised rates incorporating the lower federal corporate income tax rate for effect July 1, 2018. In the filing, Columbia of Massachusetts noted the Massachusetts DPU stated it would address the refund of any tax savings accrued from January 1, 2018, through June 30, 2018, in a separate phase of its investigation. On July 10, 2018, the Massachusetts DPU approved the tariffs effective July 1, 2018, finding the adjustment is in the public interest, as it provides an immediate benefit to ratepayers.
As noted above, on April 13, 2018, Columbia of Massachusetts filed a rate case with the Massachusetts DPU, seeking approval for an annual revenue increase of approximately $43.8 million which is offset by revenue decreases in other rate factors of $19.7 million, representing a net increase in operating revenues of $24.1 million. Included in the filing is a proposal to adjust rates and address the regulatory liability disposition related to the TCJA. Rates are expected to go into effect March 1, 2019, upon approval from the Massachusetts DPU. On June 29, 2018, Columbia of Massachusetts filed a letter with a settlement negotiations update noting the Office of the Attorney General and Columbia of Massachusetts continue to discuss the possibility of a negotiated settlement.

On July 7, 2014, the Governor of Massachusetts signed into law Chapter 149 of the Acts of 2014, An Act Relative to Natural Gas Leaks (“the Act”). The Act authorizes natural gas distribution companies to file gas infrastructure replacement plans with the Massachusetts DPU to address the replacement of aging natural gas pipeline infrastructure. In addition, the Act provides that the Massachusetts DPU may, after review of the plans, allow the proposed estimated costs of the plan into rates as of May 1 of the subsequent year. On October 31, 2017, Columbia of Massachusetts filed its GSEP for the 2018 construction year. Columbia of Massachusetts proposed to recover incremental revenue of $9.7 million associated with incremental capital investment of $83.9 million to be made during calendar year 2018. The filing included a request for approval of an alternative calculation or a waiver to allow collection of the $3.1 million revenue requirement that exceeds the GSEP cap provision as previously calculated. On January 29, 2018, Columbia of Massachusetts filed a revision to its GSEP tracker for the 2018 construction season reducing the proposed revenue requirement to reflect the impact of the TCJA. The revenue requirement was reduced by $2.4 million due to the TCJA. An order was received from the Massachusetts DPU on April 30, 2018, approving an incremental revenue requirement of $6.1 million associated with the incremental capital investment of $83.9 million, with new rates effective May 1, 2018. The order did not approve the alternative cap calculation and the portion of the revenue requirement that exceeds the GSEP cap provision. On May 21, 2018, Columbia of Massachusetts filed a motion for reconsideration on the Massachusetts DPU’s denial of Columbia of Massachusetts’s request for a waiver on the 1.5% revenue cap calculation. On June 21, 2018, the Massachusetts DPU issued an order granting a waiver on the revenue cap allowing an incremental revenue requirement of $6.5 million with new rates effective July 1, 2018.
Columbia of Pennsylvania. On February 12, 2018, the Pennsylvania PUC established a docket to investigate the impact of the TCJA on customer rates. The Pennsylvania PUC directed Pennsylvania utilities to account for any revenues associated with the difference between previous and current income tax rates and excess deferred income taxes as regulatory liabilities effective January 1, 2018. On May 17, 2018, the Pennsylvania PUC issued an order directing utilities that do not have a pending rate case to implement a negative surcharge in their billings to reflect the annual reduction in federal tax expense and associated revenue requirement for each utility, effective July 1, 2018. Since Columbia of Pennsylvania has a pending rate case, it is not required to implement the negative surcharge, and it has made a proposal in its pending rate case regarding the use of 2018 tax over-collection proceeds.
As highlighted above, on March 16, 2018, Columbia of Pennsylvania filed a rate case with the Pennsylvania PUC, seeking approval for an annual revenue increase of $46.9 million. Included in the filing is a proposal to adjust rates as a result of the TCJA. On March 21, 2018, Columbia of Pennsylvania filed a supplement to the rate case, under which it proposes to hold the overcollection of taxes during 2018 until the effective date of new base rates as credit to rate base for a period beginning January 2019 not to exceed three years. A decision on Columbia of Pennsylvania’s rate request is expected in the fourth quarter of 2018 with new rates to be implemented in December 2018.
Columbia of Virginia. On January 8, 2018, the VSCC issued an order regarding the TCJA requiring Columbia of Virginia and other Virginia utilities subject to the TCJA to accrue regulatory liabilities reflecting the impacts of the reduced corporate income tax rate effective January 1, 2018. In addition, pursuant to the order, Columbia of Virginia is required to reflect the impacts of the TCJA in its annual informational filing, including: (1) the expected cost of service impacts through calendar year 2018; (2) the amount of protected and unprotected excess accumulated deferred income taxes as of December 31, 2017, and the estimated reversal of such excess deferred income taxes during calendar year 2018; and (3) such additional information that the utility wishes to include addressing the financial and cost of service impacts of the TCJA and the appropriate treatment of the accrued regulatory liabilities. On April 25, 2018 the VSCC, by order, supplemented the above annual informational filing requirements of the January 8, 2018 order to include a proposed rate reduction that reflects the cost savings from the TCJA. This April 25, 2018 order directs that if a utility desires to propose an alternative method for returning the tax savings to customers, then it may instead file a rate case that incorporates the income tax savings. As a result of these orders, Columbia of Virginia made the decision to file a rate case. This rate case is expected to be filed by August 28, 2018.
Columbia of Kentucky. On January 26, 2018, in accordance with the Kentucky PSC investigation related to the TCJA, Columbia of Kentucky filed testimony and proposed a reduction to base rates effective May 1, 2018, to reflect the tax expense reduction as a result of the TCJA. Columbia of Kentucky was directed to account for any revenues associated with the difference between previous and current income tax rates and excess deferred income taxes as regulatory liabilities effective January 1, 2018. Columbia of Kentucky proposed to include the impact of the excess deferred taxes in rates effective October 2018 and to return the revenue related to the regulatory liability subsequent to this date. On April 30, 2018 Columbia of Kentucky received an order from the Kentucky PSC requiring implementation of interim proposed rates that are subject to future adjustment effective May 1, 2018. The order directs Columbia of Kentucky to file, by September 1, 2018, revised TCJA adjustment factors reflecting the tax expense savings from January 1, 2018, through April 30, 2018, and an estimate of the annual reduction due to the excess accumulated deferred income taxes to be effective with the first billing cycle of October 2018.

Columbia of Maryland. On February 13, 2018, Columbia of Maryland filed a proposal with the Maryland PSC to reduce rates as a result of TCJA with an annual revenue decrease of $1.3 million. Columbia of Maryland was directed to account for any revenues associated with the difference between previous and current income tax rates and excess deferred income taxes as regulatory liabilities effective January 1, 2018. On March 14, 2018, Columbia of Maryland received approval, effective April 2, 2018, to implement new rates and pass-back the overcollection of taxes from the first quarter of 2018.
On April 13, 2018, Columbia of Maryland filed a request with the Maryland PSC to increase base rates by $6.1 million, inclusive of the impacts of the TCJA. On July 31, 2018, Columbia of Maryland filed a settlement with the Maryland PSC. If approved as filed, the settlement would result in an annual revenue increase of $3.7 million. An order from the PSC is expected in the fourth quarter of 2018.
Electric Operations Regulatory Matters
Cost Recovery and Trackers. Comparability of Electric Operations line item operating results is impacted by regulatory trackers that allow for the recovery in rates of certain costs such as those described below. Increases in the expenses that are the subject of trackers result in a corresponding increase in operating revenues and therefore have essentially no impact on total operating income results.
Certain operating costs of the Electric Operations are significant, recurring in nature, and generally outside the control of NIPSCO. The IURC allows for recovery of such costs through cost tracking mechanisms. Such tracking mechanisms allow for abbreviated regulatory proceedings in order for NIPSCO to implement charges and recover appropriate costs. Tracking mechanisms allow for more timely recovery of such costs as compared with more traditional cost recovery mechanisms. Examples of such mechanisms include electric energy efficiency programs, MISO non-fuel costs and revenues, resource capacity charges, federally mandated costs and environmental-related costs.
A portion of NIPSCO's revenue is related to the recovery of fuel costs to generate power and the fuel costs related to purchased power. These costs are recovered through a FAC, a quarterly regulatory proceeding in Indiana.
As noted aboveInfrastructure Replacement and Federally-Mandated Compliance Programs
All of our operating utility companies have completed rate proceedings involving infrastructure replacement or enhancement, and have embarked upon initiatives to replace significant portions of their operating systems that are nearing the end of their useful lives. Each company's approach to cost recovery is unique, given the different laws, regulations and precedent that exist in each jurisdiction.

(3)An order on the partial settlement agreement, including the resolution of outstanding TCJA impacts to rates is currently pending before the IURC. The as-filed request and partial settlement agreement also includes $83.6 million and $85.3 million, respectively, of reductions to the fuel component of base rates related to a two phase investigation. Phase 1 solely dealtproposed change in service structure.
Additional Regulatory Matters
Columbia of Massachusetts. On December 21, 2018, the Massachusetts DPU issued an order approving the pass back of approximately $95.8 million in excess deferred taxes associated with the prospective changes inTCJA with new rates to reflect the change in tax rates. On March 26, 2018, effective on February 1, 2019.
NIPSCO filed revised electric tariffs reflecting the impact of the change in tax rate for its applicable rates and charges. The IURC approved NIPSCO's Phase 1 filing on April 26, 2018. The revised tariffs were effective May 1, 2018. On July 31, 2018, NIPSCO filed an unopposed motion requesting that the over-collection of income taxes from January 1, 2018 through April 30, 2018 be passed back in NIPSCO’s TDSIC-4 filing, also filed on July 31, 2018, and requesting that all other Phase 2 issues be handled in a rate case filing to be made in the fourth quarter of 2018. The impact on NIPSCO electric of the Phase 2 investigation is unknown at this time.
Electric. On March 29, 2018, WCE, which is currently owned by BP p.l.c ("BP") and BP Products North America, which operates the BP Refinery, filed a petition at the IURC asking that the combined operations of WCE and BP be treated as a single premise, and the WCE generation be dedicated primarily to BP Refinery operations beginning in May 2019 as WCE has self-certified as a qualifying facility at FERC. BP Refinery plansplanned to continue to purchase electric service from NIPSCO at a reduced demand level beginning in May 2019. NIPSCO is currently evaluating the impact2019; however, a settlement agreement was filed on November 2, 2018 agreeing that BP and WCE would not move forward with construction of the WCE petition, including the associated impacts on revenue. NIPSCO anticipates filing ana private transmission line to serve BP until conclusion of NIPSCO’s pending electric rate case incase. The IURC approved the fourth quarter of 2018, in part, to address anticipated revenue loss resulting from this filing. NIPSCO also anticipates filing an updated Integrated Resource Plan in the fourth quarter of 2018, which will evaluate demand-side and supply-side resource alternatives to reliably and cost effectively meet NIPSCO customers' future energy requirements over the ensuingsettlement agreement as filed on February 20, years.  
On January 30, 2018, NIPSCO made a TDSIC-3 rate adjustment mechanism filing requesting a revenue decrease of $1.8 million to be billed over six months, associated with $75.0 million of incremental capital expenditures made from May 1, 2017 to November 30, 2017. The decrease was due to the impact of the TCJA as well as a shorter billing period compared to TDSIC-2. TDSIC-3 was approved on May 30, 2018 and became effective for the first billing cycle of June. Additionally, the TDSIC-2 rates revised for tax reform approved as a part of NIPSCO’s Phase 1 filing described above were made effective on May 1, 2018, until TDSIC-3 rates went into effect. The impact of TCJA on TDSIC-2 was an approximate decrease in revenue of $1.2 million for the period from January through May 2018. NIPSCO made a TDSIC-4 rate adjustment mechanism filing on July 31, 2018 seeking an incremental semi-annual revenue decrease of $10.6 million due primarily to the pass back of a $14.1 million TCJA electric base rate customer refund for the period January through May 2018. The TCJA refund offsets a $3.5 million increase associated with $77.1 million of incremental capital expenditures from December 2017 through May 2018. An order approving the request is expected in the fourth quarter of 2018.

On February 1, 2018, NIPSCO and certain other MISO transmission owners filed with the FERC a request for waiver of tariff provisions to allow for implementation of TCJA provisions into 2018 transmission formula rates as soon as possible. On March 15, 2018, the FERC issued an order granting the request for waiver and set the effective date of the waiver at January 1, 2018. In the March billing cycle, the MISO began billing the new transmission rates reflecting the lower federal tax rate. In addition, the MISO began to re-bill January and February 2018 affected revenues and costs in the March 2018 billing cycle, and completed the re-settlement in the April 2018 billing cycle. The new 2018 transmission formula rates will lower revenue by approximately $8.5 million in 2018 associated with NIPSCO's multi-value projects.
Material Updates to Regulatory Assets and Liabilities Since December 31, 2017
TCJA-Related Regulatory Liabilities.As referenced above, during the six months ended June 30, 2018, we recorded additional TCJA-related regulatory liabilities of $65.0 million to reflect 2018 collections from customers which we believe are probable of being refunded back to customers once new customer rates are approved by our regulators.
As discussed in Note 13, "Income Taxes," in 2018 we began amortizing regulatory liabilities associated with excess deferred income taxes, which resulted in a $7.4 million and $17.8 million income tax benefit for the three and six months ended June 30, 2018, respectively. Related to this activity, we recorded an offsetting reserve of $4.7 million and $12.4 million (net of tax) in "Customer revenues" to reflect the probable future passback of this earnings benefit to customers for the three and six months ended June 30, 2018, respectively. In certain jurisdictions, we received additional regulatory guidance on the treatment and passback period of excess deferred income taxes, indicating that such a reserve was not required as of June 30, 2018.
Bailly Generating Station. During the six months ended June 30, 2018, we reclassified approximately $245 million from "Other property, at cost, less accumulated depreciation" to “Regulatory assets (noncurrent)” on the Condensed Consolidated Balance Sheets (unaudited) in connection with the retirement of Bailly Generating Station Units 7 and 8. Refer to Note 17-D, "Other Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited) for additional information.2019.
9.8.    Risk Management Activities
We are exposed to certain risks relating to our ongoing business operations, namely commodity price risk and interest rate risk. We recognize that the prudent and selective use of derivatives may help to lower our cost of debt capital, manage our interest rate exposure and limit volatility in the price of natural gas.

Commodity Price Risk Management
We, along with our utility customers, are exposed to variability in cash flows associated with natural gas purchases and volatility in natural gas prices. We purchase natural gas for sale and delivery to our retail, commercial and industrial customers, and for most customers the variability in the market price of gas is passed through in their rates. Some of our utility subsidiaries offer programs whereby variability in the market price of gas is assumed by the respective utility. The objective of our commodity price risk programs is to mitigate the gas cost variability, for us or on behalf of our customers, associated with natural gas purchases or sales by economically hedging the various gas cost components using a combination of futures, options, forwards or other derivative contracts.
NIPSCO received IURC approval to lock in a fixed price for its natural gas customers using long-term forward purchase instruments. The term of these instruments may range from five to ten years and is limited to twenty20 percent of NIPSCO’s average annual GCA purchase volume. Gains and losses on these derivative contracts are deferred as regulatory liabilities or assets and are remitted to or collected from customers through NIPSCO’s quarterly GCA mechanism. These instruments are not designated as accounting hedges.
Interest Rate Risk Management
As of June 30, 2018,2019, we have forward-starting interest rate swaps with an aggregate notional value totaling $750.0$500.0 million to hedge the variability in cash flows attributable to changes in the benchmark interest rate during the periods from the effective dates of the swaps to the anticipated dates of forecasted debt issuances, which are expected to take place by the end of 2019.2024. These interest rate swaps are designated as cash flow hedges. The effective portions of the gains and losses related to these swaps are recorded to AOCI and are recognized in "Interest expense, net" concurrently with the recognition of interest expense on the associated debt, once issued. If it becomes probable that a hedged forecasted transaction will no longer occur, the accumulated gains or losses on the derivative will be recognized currently in "Other, net."
In March 2018, we initiated settlement of forward-starting interest rate swaps with a notional value of $250.0 million. These derivative contracts were accounted for as cash flow hedges. As part of the transaction, the associated net unrealized gain of $21.2 million was recognized immediatelynet" in "Other, net" on the Condensed Statements of Consolidated Income (Loss) (unaudited) due to the probability associated with the forecasted borrowing transaction no longer occurring..
There were no amounts excluded from effectiveness testing for derivatives in cash flow hedging relationships at June 30, 20182019 and December 31, 2017.2018.
Our derivative instruments measured at fair value as of June 30, 20182019 and December 31, 20172018 do not contain any credit-risk-related contingent features.

Risk management assets and liabilities include interest rate swaps, exchange-traded NYMEX futures and NYMEX options and non-exchange-based forward purchase contracts. When utilized, exchange-traded derivative contracts are based on unadjusted quoted prices in active markets and are classified within Level 1. These financial assets and liabilities are secured with cash on deposit with the exchange; therefore, nonperformance risk has not been incorporated into these valuations. Certain non-exchange-traded derivatives are valued using broker or over-the-counter, on-line exchanges. In such cases, these non-exchange-traded derivatives are classified within Level 2. Non-exchange-based derivative instruments include swaps, forwards, options and treasury lock agreements.options. In certain instances, these instruments may utilize models to measure fair value. We use a similar model to value similar instruments. Valuation models utilize various inputs that include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, other observable inputs for the asset or liability and market-corroborated inputs, (i.e., inputs derived principally from or corroborated by observable market data by correlation or other means). Where observable inputs are available for substantially the full term of the asset or liability, the instrument is categorized within Level 2. Certain derivatives trade in less active markets with a lower availability of pricing information and models may be utilized in the valuation. When such inputs have a significant impact on the measurement of fair value, the instrument is categorized within Level 3. Credit risk is considered in the fair value calculation of derivative instruments that are not exchange-traded. Credit exposures are adjusted to reflect collateral agreements which reduce exposures. As of June 30, 20182019 and December 31, 20172018, there were no material transfers between fair value hierarchies. Additionally, there were no changes in the method or significant assumptions used to estimate the fair value of our financial instruments.
We have entered into forward-starting interest rate swaps to hedge the interest rate risk on coupon payments of forecasted issuances of long-term debt. These derivatives are designated as cash flow hedges. Credit risk is considered in the fair value calculation of each agreement. As they are based on observable data and valuations of similar instruments, the hedges are categorized within

Level 2 of the fair value hierarchy. There was no exchange of premium at the initial date of the swaps, and we can settle the contracts at any time. For additional information, see Note 9,8, "Risk Management Activities."
NIPSCO has entered into long-term forward natural gas purchase instruments that range from five to ten years to lock in a fixed price for its natural gas customers. We value these contracts using a pricing model that incorporates market-based information when available, as these instruments trade less frequently and are classified within Level 2 of the fair value hierarchy. For additional information, see Note 9,8, “Risk Management Activities.”
Available-for-sale securities are investments pledged as collateral for trust accounts related to our wholly-owned insurance company. Available-for-sale securities are included within “Other investments” in the Condensed Consolidated Balance Sheets (unaudited). We value U.S. Treasury, corporate debt and mortgage-backed securities using a matrix pricing model that incorporates market-based information. These securities trade less frequently and are classified within Level 2. Total unrealized gains and losses from available-for-sale securities are included in other comprehensive income. The amortized cost, gross unrealized gains and losses and fair value of available-for-sale securities at June 30, 20182019 and December 31, 20172018 were:

Realized gains and losses on available-for-sale securities were immaterial for the three and six months ended June 30, 20182019 and 2017.2018.
The cost of maturities sold is based upon specific identification. At June 30, 2018,2019, approximately $3.2$11.5 million of U.S. Treasury debt securities and approximately $3.7$4.2 million of Corporate/Other debt securities have maturities of less than a year.


There are no material items in the fair value reconciliation of Level 3 assets and liabilities measured at fair value on a recurring basis for the three and six months ended June 30, 20182019 and 2017.2018.


Non-recurring Fair Value Measurements. There were no significant non-recurring fair value measurements recorded during the three and six months ended June 30, 2018.2019.
B.    Other Fair Value Disclosures for Financial Instruments. The carrying amount of cash and cash equivalents, restricted cash, customer deposits and short-term borrowings is a reasonable estimate of fair value due to their liquid or short-term nature. Our long-term borrowings are recorded at historical amounts.
The following method and assumptions were used to estimate the fair value of each class of financial instruments.
Long-term Debt. The fair value of outstanding long-term debt is estimated based on the quoted market prices for the same or similar securities. Certain premium costs associated with the early settlement of long-term debt are not taken into consideration in determining fair value. These fair value measurements are classified within Level 2 of the fair value hierarchy. For the three and six months endedJune 30, 20182019, there was no change in the method or significant assumptions used to estimate the fair value of long-term debt.

11.10.    Transfers of Financial Assets
Columbia of Ohio, NIPSCO and Columbia of Pennsylvania each maintain a receivables agreement whereby they transfer their customer accounts receivables to third partythird-party financial institutions through wholly-owned and consolidated special purpose entities. The three agreements expire between August 20182019 and March 2019May 2020 and may be further extended if mutually agreed to by the parties thereto.
Table of Contents
ITEM 1. FINANCIAL STATEMENTS (continued)
NiSource Inc.
Notes to Condensed Consolidated Financial Statements (unaudited) (continued)

All receivables transferred to third parties are valued at face value, which approximates fair value due to their short-term nature. The amount of the undivided percentage ownership interest in the accounts receivables transferred is determined in part by required loss reserves under the agreements.
Transfers of accounts receivable are accounted for as secured borrowings resulting in the recognition of short-term borrowings on the Condensed Consolidated Balance Sheets (unaudited). As of June 30, 2018,2019, the maximum amount of debt that could be recognized related to our accounts receivable programs is $320.0 million.
The following table reflects the gross receivables balance and net receivables transferred as well as short-term borrowings related to the securitization transactions as of June 30, 20182019 and December 31, 2017:2018:

Fees associated with the securitization transactions were $0.7$0.6 million and $0.6$0.7 million for the three months ended June 30, 20182019 and 2017,2018, respectively and $1.5$1.4 million and $1.3$1.5 million for the six months ended June 30, 20182019 and 2017,2018, respectively. We remain responsible for collecting on the receivables securitized, and the receivables cannot be transferred to another party.

We applied the qualitative "step 0"For our annual goodwill impairment analysis to our reporting units for the annual impairment testmost recently performed as of May 1, 2018. For this test,2019, we completed a qualitative "step 0" analysis for all reporting units other than our Columbia of Massachusetts reporting unit. In the step 0 analysis, we assessed various assumptions, events and circumstances that would have affected the estimated fair value of the applicable reporting units as compared to their base linebaseline May 1, 2016 "step 1" fair value measurement. The results of this assessment indicated that it was not more likely than not that ourthe fair values of these reporting unit fair valuesunits were less than the reporting unittheir respective carrying values, accordingly, no "step 1" analysis was required.

The results of our Columbia of Massachusetts reporting unit were negatively impacted by the Greater Lawrence Incident (see Note 17, "Other Commitments and Contingencies"). As a result, we completed a quantitative "step 1" analysis for the May 1, 2019 goodwill analysis for this reporting unit. As of June 30, 2019, goodwill at Columbia of Massachusetts totaled $204.8 million. The
Table of Contents

step 1 analysis performed indicated that the fair value of the Columbia of Massachusetts reporting unit substantially exceeds its carrying value. As a result, no impairment charge was recorded as of the May 1, 2019 test date. This analysis incorporated the latest available cash flow projections reflecting the estimated ongoing impacts of the Greater Lawrence Incident on Columbia of Massachusetts' operations. We also incorporated other significant inputs to our fair value calculation (e.g. discount rate, market multiples) to reflect current market conditions. We will continue to monitor the impacts of the incident for events that could trigger a new impairment analysis including, but not limited to, unfavorable regulatory outcomes and NTSB investigation results.
13.12.    Income Taxes
Our interim effective tax rates reflect the estimated annual effective tax rates for 20182019 and 2017,2018, adjusted for tax expense associated with certain discrete items. The effective tax rates for the three months ended June 30, 2019 and 2018 were 19.6% and 2017 were 18.3% and 37.5%, respectively. The effective tax rates for the six months ended June 30, 2019 and 2018 were 20.3% and 2017 were 18.5% and 36.2%, respectively. These effective tax rates differ from the Federalfederal statutory tax rate of 21% in 2018 and 35% in 2017, primarily due to the effects of tax credits, state income taxes, the amortization of excess deferred federal income tax liabilities, as specified in the TCJA and in utility ratemaking proceedings, and other permanent book-to-tax differences.
The decreaseincrease in the three and six month effective tax raterates of 1.3% and 1.8%, respectively, in 20182019 versus the same period in 20172018 is primarily due to the changerelative impact of permanent differences on higher estimated pre-tax income in the Federal statutory rate due2019 compared to the enactment of the TCJA. Additionally, in 2018 we began amortizing a portion of our regulatory liability associated with excess deferred taxes which resulted in a current year income tax benefit of $7.4 million and $17.8 million for the three and six months ended June 30, 2018, respectively. Refer to Note 8, "Regulatory Matters," for additional information.2018.
There were no material changes recorded in 20182019 to our uncertain tax positions as of December 31, 2017.2018, however it is reasonably possible the total amount of our unrecognized tax benefits related to state tax positions will significantly change within the next 12 months. We cannot reasonably estimate the range of this potential change at this time.
14.13.    Pension and Other Postretirement Benefits
We provide defined contribution plans and noncontributory defined benefit retirement plans that cover certain of our employees. Benefits under the defined benefit retirement plans reflect the employees’ compensation, years of service and age at retirement. Additionally, we provide health care and life insurance benefits for certain retired employees. The majority of employees may

become eligible for these benefits if they reach retirement age while working for us. The expected cost of such benefits is accrued during the employees’ years of service. For most plans, cash contributions are remitted to grantor trusts.
For the six months ended June 30, 2018,2019, we contributed $1.4$1.3 million to our pension plans and $11.3$11.7 million to our other postretirement benefit plans.

14.    Long-Term Debt
On April 1, 2019, NIPSCO repaid $41.0 million of May 31, 2018, two of our qualified pension plans paid lump sums in excess of the respective plan's 2018 service cost plus interest cost, thereby meeting the requirement for settlement accounting. A settlement charge of $3.5 million was recorded during the second quarter of 2018. As a result of the settlement, these pension plans were remeasured. The remeasurements led to an increase to the pension benefit obligation, net of plan assets, of $1.1 million, a net decrease to regulatory assets of $2.3 million, and a net credit to accumulated other comprehensive loss of $0.1 million. Net periodic pension benefit cost for 2018 increased by $1.1 million as a result of the interim remeasurement.

15.    Long-Term Debt
On March 15, 2018, we redeemed $275.1 million of 6.40% senior unsecured notes at maturity.
In June 2018, we executed a tender offer for $209.0 million of outstanding notes consisting of a combination of our 6.80% notes due 2019, 5.45% notes due 2020 and 6.125% notes due 2022. In conjunction with the debt retired, we recorded a $12.5 million loss on early extinguishment of long-term debt, primarily attributable to early redemption premiums.
On June 11, 2018, we closed our private placement of $350.0 million of 3.65% senior unsecured notes maturing in 2023 which resulted in approximately $346.6 million of net proceeds after deducting commissions and expenses. We used the net proceeds from this private placement to pay a portion of the redemption price for the notes subject to the tender offer described above.
In July 2018, we redeemed $551.1 million of outstanding notes representing the remainder of our 6.80% notes due 2019, 5.45% notes due 2020 and 6.125% notes due 2022. During the third quarter of 2018, we anticipate recording a $33.0 million loss on early extinguishment of long-term debt, primarily attributable to early redemption premiums.
16.    Short-Term Borrowings
We generate short-term borrowings from our revolving credit facility, commercial paper program, letter of credit issuances, accounts receivable transfer programs and term loan borrowings. Each of these borrowing sources is described further below.
We maintain a revolving credit facility to fund ongoing working capital requirements, including the provision of liquidity support for our commercial paper program, provide for issuance of letters of credit and also for general corporate purposes. Our revolving credit facility has a program limit of $1.85 billion and is comprised of a syndicate of banks led by Barclays. On February 20, 2019, we extended the termination date of our revolving credit facility to February 20, 2024. At June 30, 20182019 and December 31, 2017,2018, we had no outstanding borrowings under this facility.
Our commercial paper program has a program limit of up to $1.5 billion with a dealer group comprised of Barclays, Citigroup, Credit Suisse and Wells Fargo. We had no$911.0 million and $978.0 million of commercial paper outstanding as of June 30, 2018 and $869.0 million outstanding as of December 31, 2017.
As of June 30, 20182019 and December 31, 2017, we had $10.2 million and $11.1 million of stand-by letters of credit,2018, respectively. All stand-by letters of credit were under the revolving credit facility.
Transfers of accounts receivable are accounted for as secured borrowings resulting in the recognition of short-term borrowings on the Condensed Consolidated Balance Sheets (unaudited). We had no$320.0 million in transfers as of June 30, 20182019 and $336.7$399.2 million as of December 31, 2017.2018. Refer to Note 11,10, "Transfers of Financial Assets," for additional information.
On April 18, 2018, we entered into a multiple-draw $600.0 million term loan agreement with a syndicate of banks led by MUFG Bank, Ltd. The term loan matures April 17, 2019, at which point any and all outstanding borrowings under the agreement are due. Interest charged on borrowings depends on the variable rate structure we elected at the time of each borrowing. Under the agreement, we borrowed an initial tranche of $150.0 million on April 18, 2018 with an interest rate of LIBOR plus 50 basis points and a second tranche of $450.0 million on May 31, 2018 with an interest rate of LIBOR plus 55 basis points.

On April 17, 2019, we amended our existing term loan agreement with a syndicate of banks, with MUFG Bank Ltd. as the Administrative Agent, Sole Lead Arranger and Sole Bookrunner. The amendment increased the amount of our term loan from $600.0 million to $850.0 million and extended the maturity date to April 16, 2020. Interest charged on borrowings depends on the variable rate structure we elect at the time of each borrowing. The available variable rate structures from which we may choose are defined in the term loan agreement. Under the agreement, we borrowed $850.0 million on April 17, 2019 with an interest rate of LIBOR plus 60 basis points.

16.    Leases
ASC 842 Adoption. In February 2016, the FASB issued ASU 2016-02, Leases (ASC 842). ASU 2016-02 introduces a lessee model that brings most leases onto the balance sheet. The standard requires that lessees recognize the following for all leases (with the exception of short-term leases, as that term is defined in the standard) at the lease commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. In 2018, the FASB issued ASU 2018-01, Leases (ASC 842): Land Easement Practical Expedient for Transition to ASC 842, which allows us to not evaluate existing land easements under ASC 842, and ASU 2018-11, Leases (ASC 842): Targeted Improvements, which allows calendar year entities to initially apply ASC 842 prospectively from January 1, 2019.
We adopted the provisions of ASC 842 beginning on January 1, 2019, using the transition method provided in ASU 2018-11, which was applied to all existing leases at that date. As such, results for reporting periods beginning after January 1, 2019 will be presented under ASC 842, while prior period amounts will continue to be reported in accordance with ASC 840. We elected a number of practical expedients, including the "practical expedient package" described in ASC 842-10-65-1 and the provisions of ASU 2018-01, which allows us to not evaluate existing land easements under ASC 842. Further, ASC 842 provides lessees the option of electing an accounting policy, by class of underlying asset, in which the lessee may choose not to separate nonlease components from lease components. We elected this practical expedient for our leases of fleet vehicles, IT assets and railcars. We elected to use a practical expedient that allows the use of hindsight in determining lease terms when evaluating leases that existed at the implementation date. We also elected the short-term lease recognition exemption, allowing us to not recognize ROU assets or lease liabilities for all leases that qualify.
Adoption of the new standard resulted in the recording of additional lease liabilities and corresponding ROU assets of $57.0 million on our Condensed Consolidated Balance Sheets (unaudited) as of January 1, 2019. The standard had no material impact on our Condensed Statements of Consolidated Income (unaudited) or our Condensed Statements of Consolidated Cash Flows (unaudited).
Lease Descriptions. We are the lessee for substantially all of our leasing activity, which includes operating and finance leases for corporate and field offices, railcars, fleet vehicles and certain IT assets. Our corporate and field office leases have remaining lease terms between 1 and 25 years with options to renew the leases for up to 25 years. We lease railcars to transport coal to and from our electric generation facilities in Indiana. Our railcars are specifically identified in the lease agreements and have lease terms between 1 and 3 years with options to renew for 1 year. Our fleet vehicles include trucks, trailers and equipment that have been customized specifically for use in the utility industry. We lease fleet vehicles on 1 year terms, after which we have the option to extend on a month-to-month basis or terminate with written notice. ROU assets and liabilities on our Condensed Consolidated
Table of Contents
ITEM 1. FINANCIAL STATEMENTS (continued)

Notes to Condensed Consolidated Financial Statements (unaudited) (continued)

Balance Sheets (unaudited) do not include obligations for possible fleet vehicle lease renewals beyond the initial lease term. While we have the ability to renew these leases beyond the initial term, we are not reasonably certain to do so.
We lease the majority of our IT assets under 4 year lease terms. Ownership of leased IT assets is transferred to us at the end of the lease term. We have not provided material residual value guarantees for our leases, nor do our leases contain material restrictions or covenants. Lease contracts containing renewal and termination options are mostly exercisable at our sole discretion. Certain of our real estate and railcar leases include renewal periods in the measurement of the lease obligation if we have deemed the renewals reasonably certain to be exercised.
With respect to service contracts involving the use of assets, if we have the right to direct the use of the asset and obtain substantially all economic benefits from the use of an asset, we account for the service contract as a lease. Unless specifically provided to us by the lessor, we utilize NiSource's collateralized incremental borrowing rate commensurate to the lease term as the discount rate for all of our leases.
Lease costs for the three and six months ended June 30, 2019 are presented in the table below. These costs include both amounts recognized in expense and amounts capitalized as part of the cost of another asset. Income statement presentation for these costs (when ultimately recognized on the income statement) is also included:

17.    Other Commitments and Contingencies
A. Guarantees and Indemnities. We and certain of our subsidiaries enter into various agreements providing financial or performance assurance to third parties on behalf of certain subsidiaries as a part of normal business. Such agreements include guarantees and stand-by letters of credit. These agreements are entered into primarily to support or enhance the creditworthiness otherwise attributed to a subsidiary on a stand-alone basis, thereby facilitating the extension of sufficient credit to accomplish the subsidiaries’ intended commercial purposes. As of June 30, 20182019 and December 31, 2017,2018, we had issued stand-by letters of credit of $10.2 million and $11.1 million, respectively. million.
B. Legal Proceedings. On September 13, 2018, a series of fires and explosions occurred in Lawrence, Andover and North Andover, Massachusetts related to the delivery of natural gas by Columbia of Massachusetts (the "Greater Lawrence Incident"). The Greater Lawrence Incident resulted in one fatality and a number of injuries, damaged multiple homes and businesses, and caused the temporary evacuation of significant portions of each municipality. The Massachusetts Governor’s Office declared a state of emergency, authorizing the Massachusetts DPU to order another utility company to coordinate the restoration of utility services in Lawrence, Andover and North Andover. The incident resulted in the interruption of gas service for approximately 7,500 gas meters, the majority of which serve residences and approximately 700 of which serve businesses, and the interruption of other utility service more broadly in the area. Columbia of Massachusetts has replaced the cast iron and bare steel gas pipeline system in the affected area and restored service to nearly all of the gas meters. See “ - D. Other Matters - Greater Lawrence Pipeline Replacement” below for more information.
We are subject to inquiries by federal and state government authorities and regulatory agencies regarding the Greater Lawrence Incident. The NTSB, the U.S Attorney’s office and the SEC have pending investigations related to the Greater Lawrence Incident, as described below. We are also subject to inquiries from the Massachusetts DPU and the Massachusetts Attorney General’s Office. We are cooperating with all inquiries and investigations. The outcomes and impacts of the current investigations and any future investigations that may be commenced related to such inquiries are uncertain at this time.
NTSB Investigation. As noted above, the NTSB is investigating the Greater Lawrence Incident. The parties to the investigation include the PHMSA, the Massachusetts DPU, Columbia of Massachusetts, and the Massachusetts State Police. We are cooperating with the NTSB and have provided information to assist in its ongoing investigation into relevant facts related to the event, the probable cause, and its development of safety recommendations.
According to the preliminary public report that the NTSB issued on October 11, 2018, an over-pressurization of a low-pressure gas distribution system occurred that was related to work being done on behalf of Columbia of Massachusetts on a pipeline replacement project in Lawrence. According to the report, sensing lines detected a drop in pressure in a portion of mainline that was being abandoned, causing a regulator to open up and increase pressure in the system to a level that exceeded the maximum allowable operating pressure of the distribution system.
On November 14, 2018, the NTSB issued an urgent safety recommendationreport regarding natural gas distribution system project development and review. In its report, the NTSB identified certain factors that it believes contributed to the Greater Lawrence Incident and made safety recommendations. The NTSB recommended that the Commonwealth of Massachusetts eliminate the

professional engineer licensure exemption for public utility work and require a professional engineer’s seal on public utility engineering drawings, which is now law in Massachusetts. The NTSB also made recommendations to us related to engineering plan and constructability review processes, records and documentation, management of change processes, and control procedures during modifications to gas mains. We are in the process of implementing these recommendations. The NTSB investigation is ongoing. While the NTSB investigation is pending, we are prohibited from disclosing information related to the investigation without approval from the NTSB.
Since the Greater Lawrence Incident, we have identified, and moved ahead with, additional steps to enhance system safety and reliability and to safeguard against over-pressurization. Some of these measures have already been completed and others are in process. These Company-wide safety measures will include enhanced measures as called for in the NTSB’s recommendations. We have committed to a program to install over-pressurization protection devices on all of our low-pressure systems, which is described in “ - D. Other Matters.”
Massachusetts Regulatory and Legislative Matters. Under Massachusetts law, the DPU is authorized to investigate potential violations of pipeline safety regulations and to assess a civil penalty of up to $209,000 for a violation of federal pipeline safety regulations. A separate violation occurs for each day of violation up to $2.1 million for a related series of violations. The Massachusetts DPU also is authorized to investigate potential violations of the Columbia of Massachusetts emergency response plan and to assess penalties of up to $250,000 per violation per day, or up to $20 million per related series of violations. Further, as a result of the declaration of emergency by the Governor, the DPU is authorized to investigate potential violations of the DPU's operational directives during the restoration efforts and assess penalties of up to $1 million per violation. Pursuant to these authorities, the DPU has conducted an initial investigation in connection with the Greater Lawrence Incident. Columbia of Massachusetts is subject to further investigation by the DPU or a potential compliance action, the timing and outcome of which are uncertain at this time.
The Massachusetts DPU has retained an independent evaluator to conduct a statewide examination of the safety of the natural gas distribution system and the operational and maintenance functions of natural gas companies in the Commonwealth of Massachusetts. Through authority granted by the Massachusetts Governor under the state of emergency, the Chair of the Massachusetts DPU will direct all natural gas distribution companies operating in the Commonwealth to fund the statewide examination. The statewide examination is underway and we have responded to the evaluator’s information requests. The Phase I report, which was issued on May 15, 2019, included a program level assessment and evaluation of natural gas distribution companies. The Phase I report's conclusions were statewide and contained no specific conclusions about Columbia of Massachusetts. The evaluation has now entered Phase II, which is focused on field assessments of each individual gas company and is expected to conclude later this year.
On November 30, 2018, Columbia of Massachusetts entered into a consent order with the Massachusetts DPU in connection with a notice of probable violation issued in March 2018, stemming from a 2016 report. The Division found that Columbia of Massachusetts violated certain pipeline safety regulations related to pressure limiting and regulating stations in Taunton, Massachusetts. As part of the consent order, Columbia of Massachusetts was fined $75,000 and entered into a compliance agreement under which it agreed to take several actions related to its pressure regulator stations within various timeframes, including the adoption of a Pipeline Safety Management System ("SMS"), the American Petroleum Institute’s (API) Recommended Practice 1173. Columbia of Massachusetts is complying with the order.
On December 17, 2018, the Massachusetts DPU issued an order requiring Columbia of Massachusetts to enter into an agreement with a Massachusetts-based engineering firm to monitor Columbia of Massachusetts’ remaining restoration and recovery work in Lawrence, Andover and North Andover, Massachusetts. The order requires Columbia of Massachusetts to take measures to ensure that adequate heat and hot water and gas appliances are provided to all affected properties, repave all affected streets, roadways, sidewalks and other areas in accordance with applicable DPU standards and precedents, consult with the affected communities and discuss plans for restoring affected hard or soft surfaces, and replace all gas boilers and furnaces and other gas-fired equipment at affected residences. Under the order, all restoration work beginning in 2019 is required to be completed no later than October 31, 2019, unless an earlier or later date is agreed to with any of the affected communities. We have agreed to complete the gas appliance replacement work by September 15, 2019. We have also reached an agreement with the affected communities with regard to the timing and scope of hard and soft surface repairs, which is discussed in "Private Actions" below. On June 11, 2019, the Massachusetts DPU issued an order requiring Columbia of Massachusetts to comply with the terms of the agreement reached with the affected communities for the restoration of hard and soft surfaces. Also, under both the December 17, 2018 and June 11, 2019 orders, Columbia of Massachusetts is required to maintain quantitative measures, which must be verified by officials of the affected communities, to track its progress in completing all of the remaining work. Estimates for the cost of this work are included in the estimated ranges of loss noted below, which is discussed in “- D. Other Matters - Greater Lawrence Incident Restoration"

and " - Greater Lawrence Pipeline Replacement” below. Our failure to adhere to any of the requirements in the order may result in penalties of up to $1 million per violation.
In December 2018, the President of Columbia of Massachusetts testified before a joint state legislative committee on telecommunications, utilities and energy with other industry officials about gas system safety in Massachusetts and regulatory oversight. Increased scrutiny related to these matters, including additional legislative oversight hearings and new legislative proposals, is expected to continue during the current two-year legislative session.
On December 31, 2018, the Massachusetts Governor signed into law legislation requiring a certified professional engineer to review and approve gas pipeline work that could pose a “material risk” to public safety, consistent with the NTSB’s recommendation. The Massachusetts DPU has issued interim guidelines and the existing moratorium has been lifted. The DPU issued an Order Opening Inquiry (Notice of Inquiry) on March 18, 2019, and Columbia of Massachusetts has submitted comments.
U.S. Department of Justice Investigation. The Company and Columbia of Massachusetts are subject to a criminal investigation related to the Greater Lawrence Incident that is being conducted under the supervision of the U.S. Attorney's Office for the District of Massachusetts. The initial grand jurysubpoenas were served on the Company and Columbia of Massachusetts on September 24, 2018. The Company and Columbia of Massachusetts are cooperating with the investigation. We are unable to estimate the amount (or range of amounts) of reasonably possible losses associated with any civil or criminal penalties that could be imposed on the Company or Columbia of Massachusetts.
U.S. Congressional Hearing. In November 2018, executives of the Company and Columbia of Massachusetts testified at a U.S. Senate hearing regarding the Greater Lawrence Incident and natural gas pipeline safety. Increased scrutiny related to these matters, including additional federal congressional hearings and new legislative proposals, is expected to continue through 2019.
SEC Investigation. On February 11, 2019, the SEC notified the Company that it is conducting an investigation of the Company related to disclosures made prior to the Greater Lawrence Incident. We are cooperating with the investigation.
Private Actions. Various lawsuits, including several purported class action lawsuits, have been filed by various affected residents or businesses in Massachusetts state courts against the Company and/or Columbia of Massachusetts in connection with the Greater Lawrence Incident. A special judge has been appointed to hear all pending and future cases and the class actions will be consolidated into one class action. On January 14, 2019, the special judge granted the parties’ joint motion to stay all cases until April 30, 2019 to allow mediation, and the parties subsequently agreed to extend the stay until July 25, 2019. The class action lawsuits allege varying causes of action, including those for strict liability for ultra-hazardous activity, negligence, private nuisance, public nuisance, premises liability, trespass, breach of warranty, breach of contract, failure to warn, unjust enrichment, consumer protection act claims, negligent, reckless and intentional infliction of emotional distress and gross negligence, and seek actual compensatory damages, plus treble damages, and punitive damages.
On July 26, 2019, the Company, Columbia of Massachusetts and NiSource Corporate Services Company, a subsidiary of the Company, entered into a term sheet with the class action plaintiffs under which they agreed to settle the class action claims in connection with the Greater Lawrence Incident. Columbia of Massachusetts agreed to pay $143 million into a settlement fund to compensate the settlement class and the settlement class agreed to release Columbia of Massachusetts and affiliates from all claims arising out of or related to the Greater Lawrence Incident. The following claims are not covered under the proposed settlement because they are not part of the consolidated class action: (1) physical bodily injury and wrongful death; (2) insurance subrogation, whether equitable, contractual or otherwise; and (3) claims arising out of appliances that are subject to the Massachusetts DPU orders. Emotional distress and similar claims are covered under the proposed settlement unless they are secondary to a physical bodily injury. The settlement class is defined under the term sheet as all persons and businesses in the three municipalities of Lawrence, Andover and North Andover, Massachusetts, subject to certain limited exceptions. The proposed settlement is subject to negotiation and execution of a final settlement agreement, and preliminary and final court approvals.
Many residents and business owners have submitted individual damage claims to Columbia of Massachusetts. We also have received notice from three parties indicating an intent to assert wrongful death claims. In Massachusetts, punitive damages are available in a wrongful death action upon proof of gross negligence or willful or reckless conduct causing the death. In addition, the Commonwealth of Massachusetts is seeking reimbursement from Columbia of Massachusetts for its expenses incurred in connection with the Greater Lawrence Incident. The outcomes and impacts of such private actions are uncertain at this time except as set forth below.
We are discussing potential settlements with plaintiffs asserting certain bodily injury and wrongful death claims. On April 25, 2019, we entered into a settlement agreement with certain of these plaintiffs involving bodily injury claims, subject to certain

conditions, including court approval. On July 3, 2019, we entered into a settlement with one of the parties that indicated an intent to assert a wrongful death claim.
On May 7, 2019, Columbia of Massachusetts and the municipalities of Lawrence, Andover and North Andover jointly announced that they reached a settlement for expenses incurred by the municipalities in connection with the Greater Lawrence Incident, and for compensating the municipalities to repave affected streets, roadways and sidewalks.
Financial Impact. We estimate that total costs related to third-party claims resulting from the incident will range from $994 million to $1,020 million, depending on the final outcome of ongoing reviews and the number, nature, and value of third-party claims. These costs include, but are not limited to, personal injury and property damage claims, damage to infrastructure, and mutual aid payments to other utilities assisting with the restoration effort. These costs related to third-party claims do not include costs of certain third-party claims that we are not able to estimate, nor do they include non-claims related expenses resulting from the incident and the estimated capital cost of the pipeline replacement, which are set forth in " - D. Other Matters - Greater Lawrence Incident Restoration" and "- Greater Lawrence Incident Pipeline Replacement," respectively, below.
The process for estimating costs associated with third-party claims relating to the Greater Lawrence Incident requires management to exercise significant judgment based on a number of assumptions and subjective factors. As more information becomes known, including additional information resulting from the NTSB investigation and private actions, management’s estimates and assumptions regarding the financial impact of the Greater Lawrence Incident may change. The increase in estimated total costs related to third-party claims from those disclosed in our Form 10-K for the year ended December 31, 2018 resulted primarily from receiving additional information regarding legal claims and the required scope of the restoration work inside the affected homes.
It is not possible at this time to reasonably estimate the total amount of any expenses associated with government investigations and fines, penalties or settlements with certain governmental authorities, including the Massachusetts DPU and other regulators, that we may incur in connection with the Greater Lawrence Incident. Therefore, the foregoing amounts do not include estimates of the total amount that we may incur for any such fines, penalties or settlements.
The aggregate amount of third-party liability insurance coverage available for losses arising from the Greater Lawrence Incident is $800 million. Total expenses related to the incident have exceeded the total amount of insurance coverage available under our policies. While a substantial amount of expenses related to the Greater Lawrence Incident has already been recovered from insurance carriers, a few insurers providing liability insurance to the Company or Columbia of Massachusetts continue to review our claim under the terms and conditions of the respective insurance policies. We are not able to estimate the amount of expenses that will not be covered by insurance, but these amounts are material to our financial statements. Certain types of damages, expenses or claimed costs, such as fines or penalties, may be excluded under the policies.
Refer to "- D. Other Matters - Greater Lawrence Incident Restoration," below for a summary of third-party claims-related expense activity and associated insurance recoveries recorded since the Greater Lawrence Incident.
In addition, we are party to certain other claims and legal proceedings arising in the ordinary course of business, none of which areis deemed to be individually material at this time.
Due to the inherent uncertainty of litigation, there can be no assurance that the resolution of any particular claim or proceeding related to the Greater Lawrence Incident or otherwise would not have a material adverse effect on our results of operations, financial position or liquidity. If one or more of such matters were decided against us, the effects could be material to our results of operations in the period in which we would be required to record or adjust the related liability and could also be material to our cash flows in the periods that we would be required to pay such liability.
C. Environmental Matters. Our operations are subject to environmental statutes and regulations related to air quality, water quality, hazardous waste and solid waste. We believe that we are in substantial compliance with the environmental regulations currently applicable to our operations.
It is management's continued intent to address environmental issues in cooperation with regulatory authorities in such a manner as to achieve mutually acceptable compliance plans. However, there can be no assurance that fines and penalties will not be incurred. Management expects a significant portion of environmental assessment and remediation costs to be recoverable through rates for certain of our companies.
As of June 30, 20182019 and December 31, 2017,2018, we had recorded a liability of approximately $109.7$108.5 million and $111.4$101.2 million, respectively, to cover environmental remediation at various sites. The current portion of this liability is included in "Legal and environmental" in the Condensed Consolidated Balance Sheets (unaudited). The noncurrent portion is included in "Other noncurrent liabilities" in the. We

recognize costs associated with environmental remediation obligations when the incurrence of such costs is probable and the amounts can be reasonably estimated. The original estimates for remediation activities may differ materially from the amount ultimately expended. The actual future expenditures depend on many factors, including currently enacted laws and regulations, the nature and extent of impact and the method of remediation. These expenditures are not currently estimable at some sites. We periodically adjust our liability as information is collected and estimates become more refined.
Electric Operations' compliance estimates disclosed below are reflective of NIPSCO's Integrated Resource Plan submitted to the IURC on November 1, 2016.October 31, 2018. See section D, "Other Matters NIPSCO 2018 Integrated Resource Plan," below for additional information.

The actions listed below could require further reductions in emissions from various emission sources. We will continue to closely monitor developments in these matters.
Future legislative and regulatory programs could significantly limit allowed GHG emissions or impose a cost or tax on GHG emissions. Additionally, rules that increase methane leak detection, require emission reductions or impose additional requirements

for natural gas facilities could restrict GHG emissions and impose additional costs. We carefully monitor all GHG reduction proposals and regulations.
Clean Power Plan.CPP and ACE Rules. On October 23, 2015,July 8, 2019, the EPA issued apublished the final ACE rule to regulate CO2 emissions from existing fossil-fuel EGUs under section 111(d) ofand repealed the CAA.CPP. The finalACE rule establishes national CO2 emission-rateemission guidelines for states to use when developing plans to limit carbon dioxide at coal-fired electric generating units based on heat rate improvement measures. The coal-fired units at NIPSCO’s R.M. Schahfer Generating Station and Michigan City Generating Station are potentially affected sources, and compliance requirements for these units which NIPSCO plans to retire by 2023 and 2028, respectively, will be determined by future Indiana rulemaking. The ACE rule notes that states have “broad flexibility in setting standards that are applied to each state’s mix of affected EGUs to establish state-specific emission-rateperformance for designated facilities” and mass-emission limits. The final rule requires each state to submit a plan indicating how the state will meet the EPA's emission-rate or mass-emission limit, including possibly imposing reduction obligations on specific units. Ifthat a state does not submitmay set a satisfactory plan,“business as usual” standard for sources that have a remaining useful life “so short that imposing any costs on the electric generating unit is unreasonable.” State plans are due by 2022, and the EPA will imposehave six months to determine completeness and then one additional year to determine whether to approve the submitted plan. States have the discretion to determine the compliance period for each source. As a federal plan on that state.

On February 9, 2016, the U.S. Supreme Court stayed implementation of the CPP until litigation is decided on its merits. On October 16, 2017, the EPA published in the Federal Register a Notice of Proposed Rulemaking that would repeal the CPP. On December 28, 2017, in a separate but related action, the EPA published an Advanced Notice of Proposed Rulemaking in the Federal Register to solicit information from the public about a potential future rulemaking to limit greenhouse gas emissions from existing fossil-fuel EGUs.result, NIPSCO will continue to monitor this matter and cannot estimate its impact at this time. Should costs be incurred to comply with the CPP, NIPSCO believes such costs will be eligible for recovery through customer rates.
Waste
CERCLA. Our subsidiaries are potentially responsible parties at waste disposal sites under the CERCLA (commonly known as Superfund) and similar state laws. Under CERCLA, each potentially responsible party can be held jointly, severally and strictly liable for the remediation costs as the EPA, or state, can allow the parties to pay for remedial action or perform remedial action themselves and request reimbursement from the potentially responsible parties. Our affiliates have retained CERCLA environmental liabilities, including remediation liabilities, associated with certain current and former operations. These liabilities are not material to the Condensed Consolidated Financial Statements (unaudited).
MGP. A program has been instituted to identify and investigate former MGP sites where Gas Distribution Operations subsidiaries or predecessors may have liability. The program has identified 6463 such sites where liability is probable. Remedial actions at many of these sites are being overseen by state or federal environmental agencies through consent agreements or voluntary remediation agreements.
We utilize a probabilistic model to estimate our future remediation costs related to our MGP sites. The model was prepared with the assistance of a third party and incorporates our experience and general industry experience with remediating MGP sites. We complete an annual refresh of the model in the second quarter of each fiscal year. No material changes to the estimated future remediation costs were noted as a result of the refresh completed as of June 30, 2018.2019. Our total estimated liability related to the facilities subject to remediation was $105.5$105.4 million and $106.9$97.5 million at June 30, 20182019 and December 31, 2017,2018, respectively. The liability represents our best estimate of the probable cost to remediate the facilities. We believe that it is reasonably possible that remediation costs could vary by as much as $25$20 million in addition to the costs noted above. Remediation costs are estimated based on the best available information, applicable remediation standards at the balance sheet date and experience with similar facilities.
CCRs. On April 17, 2015, the EPA issued a final rule for regulation of CCRs. The rule regulates CCRs under the RCRA Subtitle D, which determines them to be nonhazardous. The rule is implemented in phases and requires increased groundwater monitoring, reporting, recordkeeping and posting of related information to the Internet. The rule also establishes requirements related to CCR management and disposal. The rule will allowallows NIPSCO to continue its byproduct beneficial use program.
To comply with the rule, NIPSCO incurred capital expenditures to modify its infrastructure and manage CCRs. The publication of the CCR rule also resulted in revisions to previously recorded legal obligations associated with the retirement of certain NIPSCO facilities. The actual asset retirement costs related to the CCR rule may vary substantially from the estimates used to record the increased asset retirement

obligation due to the uncertainty about the compliance strategies that will be used and the preliminary nature of available data used to estimate costs. In addition, to comply with the rule, NIPSCO will be required to incur future capital expenditures to modify its infrastructure and manage CCRs. Capital compliance costs are currently expected to total approximately $193 million. As allowed by the EPA, NIPSCO will continue to collect data over time to determine the specific compliance solutions and associated costs and, as a result, the actual costs may vary.
NIPSCO has filed a petition on November 1, 2016initial CCR closure plans for R.M. Schahfer Generating Station and Michigan City Generating Station with the IURC seeking approvalIndiana Department of the projects and recovery of the costs associated with CCR compliance. On June 9, 2017, NIPSCO filed with the IURC a settlement reached with certain parties regarding the CCR projects and treatment of associated costs. The IURC approved the settlement in an order on December 13, 2017.

Environmental Management.
Water
ELG. On November 3, 2015, the EPA issued a final rule to amend the ELG and standards for the Steam Electric Power Generating category. The final rule became effective January 4, 2016. The rule imposes new water treatment and discharge requirements on NIPSCO's electric generating facilities to be applied between 2018 and 2023. On April 25, 2017, the EPA published notice in the Federal Register that the EPA is reconsidering the ELG in response to several petitions for reconsideration. On September 18, 2017, the EPA postponed the earliest compliance dates for flue gas desulfurization wastewater and bottom ash transport water requirements from 2018 to 2020 to potentially consider revisions to technology and numeric limits achievable. NIPSCO is unable to estimate the financial impact of the EPA reconsideration at this time. Based upon a preliminary study of the November 3, 2015 final rule, capital compliance costs were expected to be approximately $170 million. On November 1, 2016,The EPA is expected to release a draft ELG reconsideration rule in 2019. However, NIPSCO filed a petition withdoes not anticipate material ELG compliance costs based on the IURC seeking approval of the projects and recovery of the costs associated with ELG compliance. Given the current postponement of certain compliance dates under the ELG rule, NIPSCO has agreed with the settling parties,preferred option announced as part of the settlement agreement discussed in the "CCRs" subsection above, that these ELG projects and related costs would be addressed in a later proceeding.NIPSCO's 2018 Integrated Resource Plan (discussed below).
D.D. Other Matters.
NIPSCO 20162018 Integrated Resource Plan.Environmental, regulatory andMultiple factors, but primarily economic factors,ones, including low natural gas prices, advancing cost effective renewable technology and aging coal-fired units,increasing capital and operating costs associated with existing coal plants, have led NIPSCO to pursue modification ofconclude in its current electric generation supply mix to include less coal-fired generation. Due to enacted CCR and ELG (subsequently postponed) regulations, NIPSCO would expect to have incurred over $1 billion in operating, maintenance, environmental and other costs if theOctober 2018 Integrated Resource Plan submission that NIPSCO’s current fleet of coal-fired generating units were to remain operational.
On November 1, 2016, NIPSCO submitted its 2016coal generation facilities will be retired earlier than previous Integrated Resource Plan with the IURC. Plan’s had indicated.
The planIntegrated Resource Plan evaluated demand-side and supply-side resource alternatives to reliably and cost effectively meet NIPSCO customers' future energy requirements over the ensuing 20 years. The 2016preferred option within the Integrated Resource Plan indicated that the most viable option for customersretires R.M. Schahfer Generating Station (Units 14, 15, 17, and NIPSCO involves18) by 2023 and Michigan City Generating Station (Unit 12) by 2028. These units represent 2,080 MW of generating capacity, equal to 72% of NIPSCO’s remaining generating capacity (and 100% of NIPSCO's remaining coal-fired generating capacity) after the retirement of Bailly Generating Station (UnitsUnits 7 and 8) as soon as mid-2018 and two units (Units 17 and 18) at the R.M. Schahfer Generating Station by 2023. It is projected over the long term that the cost to customers to retire these units at these dates will be lower than maintaining and upgrading them for continued generation.
We committed to the retirement of the Bailly Generating Station units in connection with the filing of the 2016 Integrated Resource Plan, pending approval by the MISO. In the fourth quarter of 2016, the MISO approved NIPSCO's plan to retire the Bailly Generating Station units by8 on May 31, 2018.
On February 1, 2018, as previously approvedThe current replacement plan includes renewable sources of energy, including wind, solar, and battery storage to be obtained through a combination of NIPSCO ownership and PPAs.
In January 2019, NIPSCO executed two 20 year PPAs to purchase 100% of the output from renewable generation facilities at a fixed price per MW. The facilities supplying the energy will have a combined nameplate capacity of approximately 700 MW. NIPSCO's purchase requirement under the PPAs is dependent on satisfactory approval of the PPAs by the MISO,IURC. NIPSCO commenced a four-month outage of Bailly Generating Station Unit 8submitted the PPAs to the IURC for approval in order toFebruary 2019 and the IURC approved the PPAs on June 5, 2019. Payments under the PPAs will not begin work on convertinguntil the unit to a synchronous condenser (a piece of equipment designed to maintain voltage to ensure continued reliability onassociated generation facilities are constructed by the transmission system). Approximately $15 million of net book value of Unit 8 remained in “Net Utility Plant” as itowner / seller which is currently expected to remain used and useful upon completion of the synchronous condenser, while the remaining net book value of approximately $142 million was reclassified to “Regulatory assets (noncurrent)” on the Condensed Consolidated Balance Sheets (unaudited). On May 31, 2018, Units 7 and 8 were retired from service. As a result, the remaining net book value of Unit 7 of approximately $103 million was reclassified to “Regulatory assets (noncurrent)” on the Condensed Consolidated Balance Sheets (unaudited).These amounts continue to be amortized at a rate consistent with their inclusion in customer rates.
NIPSCO anticipates updating its Integrated Resource Plan in a filingcomplete by the end of 2018.
NIPSCO Pure Air. NIPSCO had a service agreement with Pure Air, a general partnership between Air Products2020 for one facility and Chemicals, Inc. and First Air Partners LP, under which Pure Air provided scrubber services to reduce sulfur dioxide emissions for Units 7 and 8 atby the Bailly Generating Station. Services under this contract commenced on July 1, 1992 and expired on June 30, 2012. The agreement was renewed effective July 1, 2012 for ten years, requiring NIPSCO to payend of 2021 for the services underother facility.
Also in January 2019, NIPSCO executed a combinationBTA with a developer to construct a renewable generation facility with a nameplate capacity of fixed and variable charges. We made an exhaustive effort to obtain information needed from Pure Air to determine the status of Pure Air as a VIE. However, NIPSCO was not able to obtain this information and, as a result, it was not determined whether Pure Air was a VIE and whether NIPSCO was the primary beneficiary. Payments under this agreement were $7.6 million and $10.4 million for the six months ended June 30, 2018 and 2017, respectively. In accordance with GAAP, the renewed agreement was evaluated to determine whether the arrangement qualified as a lease. Based on the termsapproximately 100 MW. Once complete, ownership of the agreement,facility would be transferred to a partnership owned by NIPSCO, the arrangement qualified for capital lease accounting. Asdeveloper and an unrelated tax equity partner. The aforementioned partnership structure will result in full NIPSCO ownership after the effective datePTC are monetized from the project (approximately 10 years after the facility goes into service). NIPSCO's purchase requirement under the BTA is dependent on satisfactory approval of the new agreement was July 1, 2012, we capitalized this lease beginningBTA by the IURC and timely completion of construction. NIPSCO submitted the BTA to the IURC for approval in February 2019. An IURC order is anticipated in the third quarter of 2012.2019. Required FERC filings will occur after receiving the IURC order. Construction of the facility is expected to be complete by the end of 2020.
Greater Lawrence Incident Restoration. In addition to the amounts estimated for third-party claims described above, we estimate we will incur other incident-related costs totaling between $430 million and $440 million, depending on the incurrence of future restoration work. Such costs include certain consulting costs, claims center costs, labor and related expenses incurred in connection with the incident and insurance-related loss surcharges. The amounts set forth above do not include the estimated capital cost of the pipeline replacement, which is set forth below in - D. Other Matters - Greater Lawrence Pipeline Replacement." The increase in estimated total incident-related expenses from those disclosed in our Form 10-K for the year ended December 31, 2018 resulted primarily from receiving additional information regarding the extended period of time over which the restoration work would take place, higher than anticipated costs from vendors, expenses associated with government investigations, the incurrence of insurance-related loss surcharges and increased estimates for consultants and claim center costs.
As further discussed above in this Note 17- B. Legal Proceedings, the aggregate amount of third-party liability insurance coverage available for losses arising from the Greater Lawrence Incident is $800 million. Expenses related to the incident have exceeded the total amount of insurance coverage available under our policies. While a substantial amount of expenses related to the heading "NIPSCO 2016 Integrated Resource Plan," NIPSCO retiredGreater Lawrence Incident has already been recovered from insurance, a few insurers providing liability insurance to the generation station units serviced by Pure Air on May 31, 2018.

Greater Lawrence Pipeline Replacement. In connection with the closureGreater Lawrence Incident, Columbia of Bailly Units 7Massachusetts, in cooperation with the Massachusetts Governor’s office, replaced the entire affected 45-mile cast iron and 8, NIPSCO paidbare steel pipeline system that delivers gas to approximately 7,500 gas meters, the termination paymentmajority of which serve residences and approximately 700 of which serve businesses impacted in the Greater Lawrence Incident. This system was replaced with plastic distribution mains and service lines, as well as enhanced safety features such as pressure regulation and excess flow valves at each premise. At the request of the Massachusetts DPU, which was instructed by the Massachusetts Governor through his executive authority under a state of emergency, Columbia of Massachusetts hired an outside contractor to Pure Air duringserve as the second quarterChief Recovery Officer for the Greater Lawrence Incident, responsible for command, control and communications. Columbia of Massachusetts restored gas service to nearly all homes and workplaces in December 2018. Cash flows associatedWith the restoration and recovery efforts now substantially complete, the service of the Chief Recovery Officer is complete and the next phase of the effort is being managed by Columbia of Massachusetts under the third party oversight of a Massachusetts-based engineering firm as set forth above under “ - B. Legal Proceedings.”
Since the Greater Lawrence Incident and through June 30, 2019, we have invested approximately $250 million of capital spend for the pipeline replacement. We estimate this replacement work will ultimately cost between $250 million and $260 million. We maintain property insurance for gas pipelines and other applicable property in the approximate amount of $300 million. Columbia of Massachusetts has filed a claim with this payment are presented within operating activities onits property insurer and discussions around the Condensed Statements of Consolidated Cash Flows (unaudited).claim and recovery have commenced.

The outcome of such a proceeding is uncertain. In accordance with ASC 980-360, if it becomes probable that a portion of the pipeline replacement cost will not be recoverable through customer rates and an amount can be reasonably estimated, we will reduce our regulated plant balance for the amount of the probable disallowance and record an associated charge to earnings. This could result in a material adverse effect to our financial condition, results of operations and cash flows. Additionally, if a rate order is received allowing recovery of the investment with no or reduced return on investment, a loss on disallowance may be required.

20.    Business Segment Information
OurAt June 30, 2019, our operations are divided into two primary reportable segments. The Gas Distribution Operations segment provides natural gas service and transportation for residential, commercial and industrial customers in Ohio, Pennsylvania, Virginia, Kentucky, Maryland, Indiana and Massachusetts. The Electric Operations segment provides electric service in 20 counties in the northern part of Indiana.
The following table provides information about our business segments. We use operating income as our primary measurement for each of the reported segments and make decisions on finance, dividends and taxes at the corporate level on a consolidated basis. Segment revenues include intersegment sales to affiliated subsidiaries, which are eliminated in consolidation. Affiliated sales are recognized on the basis of prevailing market, regulated prices or at levels provided for under contractual agreements. Operating income is derived from revenues and expenses directly associated with each segment.

EXECUTIVE SUMMARY




This Management’s Discussion and Analysis of Financial Condition and Results of Operations (Management’s Discussion) analyzes our financial condition, results of operations and cash flows and those of our subsidiaries. It also includes management’s analysis of past financial results and certain potential factors that may affect future results, potential future risks and approaches that may be used to manage those risks. See "Note regarding forward-looking statements" at the beginning of this report for a list of factors that may cause results to differ materially.
Management’s Discussion is designed to provide an understanding of our operations and financial performance and should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2017.2018.
We are an energy holding company under the Public Utility Holding Company Act of 2005 whose subsidiaries are fully regulated natural gas and electric utility companies serving customers in seven states. We generate substantially all of our operating income through these rate-regulated businesses which are summarized for financial reporting purposes into two primary reportable segments: Gas Distribution Operations and Electric Operations.
Refer to the “Business” section of our Annual Report on Form 10-K for the fiscal year ended December 31, 20172018 for further discussion of our regulated utility business segments.
Our goal is to develop strategies that benefit all stakeholders as we address changing customer conservation patterns, develop more contemporary pricing structures and embark on long-term investment programs. These strategies are intended to improve reliability and safety, enhance customer service and reduce emissions while generating sustainable returns. Additionally, we continue to pursue regulatory and legislative initiatives that will allow residential customers not currently on our system to obtain gas service in a cost effective manner.
Greater Lawrence Incident: The Greater Lawrence Incident occurred on September 13, 2018. The following table summarizes expenses incurred and insurance recoveries recorded since the Greater Lawrence Incident. The amounts set forth in the table below do not include the estimated capital cost of the pipeline replacement described below and as set forth in Note 17- D, "Other Matters - Greater Lawrence Pipeline Replacement," in the Notes to Condensed Consolidated Financial Statements (unaudited).

Including the $757 million recorded during 2018, we estimate that total costs related to third-party claims as set forth in Note 17, "Other Commitments and Contingencies - B. Legal Proceedings," will range from $994 million to $1,020 million, depending on the final outcome of ongoing reviews and the number, nature and value of third-party claims. We expect to incur a total of $430 million to $440 million in other incident-related costs, inclusive of the $266 million recorded during 2018 as set forth in Note 17, "Other Commitments and Contingencies - D. Other Matters .
We also expect to incur other expenses, including expenses associated with government investigations and fines, penalties or settlements with governmental authorities in connection with the Greater Lawrence Incident, the amounts and timing of which cannot be estimated at this time.

(1)Additional collections of insurance proceeds in the amount of $125 million were received subsequent to the June 30, 2019 balance sheet date.
To the extent that we are not successful in collecting reimbursement in the amount recorded for such recoveries as of June 30, 2019, it could result in a charge to earnings. We are currently unable to predict the timing or amount of future insurance recoveries in excess of that currently recorded in Accounts Receivable
Since the Greater Lawrence Incident and through June 30, 2019, we have invested approximately $250 million of capital spend for the pipeline replacement. We estimate this replacement work will ultimately cost between $250 million and $260 million. Columbia of Massachusetts has filed a claim with its property insurer of the Greater Lawrence Incident and discussions around the claim and recovery have commenced. The recovery of any capital investment not reimbursed through insurance will be addressed in a future regulatory proceeding. The outcome of such a proceeding is uncertain. If at any point Columbia of Massachusetts concludes it is probable that any portion of this capital investment is not recoverable through customer rates, that portion of the capital investment, if estimable, would be immediately charged to earnings.
Refer to Note 17-B and D, "Legal Proceedings" and "Other Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited), "Summary of Consolidated Financial Results," "Results and Discussion of Segment Operation - Gas Distribution Operations," and "Liquidity and Capital Resources" in this Management's Discussion for additional information related to the Greater Lawrence Incident.
Summary of Consolidated Financial Results
Our operations are affected by the cost of sales. Cost of sales for the Gas Distribution Operations segment is principally comprised of the cost of natural gas used while providing transportation and distribution services to customers. Cost of sales for the Electric Operations segment is comprised of the cost of coal, related handling costs, natural gas purchased for the internal generation of electricity at NIPSCO and the cost of power purchased from third-party generators of electricity.
The majority of the cost of sales are tracked costs that are passed through directly to the customer, resulting in an equal and offsetting amount reflected in operating revenues. As a result, we believe net revenues, a non-GAAP financial measure defined as operating revenues less cost of sales (excluding depreciation and amortization), provides management and investors a useful measure to analyze profitability. The presentation of net revenues herein is intended to provide supplemental information for investors regarding operating performance. Net revenues do not intend to represent operating income, the most comparable GAAP measure, as an indicator of operating performance and are not necessarily comparable to similarly titled measures reported by other companies.

On a consolidated basis, we reported net income available to common shareholders of $283.1 million, or $0.76 per basic share for the three months ended June 30, 2019, compared to net income available to common shareholders of $23.2 million, or $0.07 per basic share for the threesame period in 2018. The increase in income available to common shareholders during 2019 was primarily due to lower operating expenses due to insurance recoveries recorded related to the Greater Lawrence Incident and an increase in revenue due to new rates from base rate proceedings and infrastructure replacement programs.
For the six months ended June 30, 2018, compared to a net loss available to common shareholders of $44.4 million, or $0.14 per basic share for the same period in 2017. The increase in2019, we reported net income available to common shareholders during 2018 was due primarily to a loss on early extinguishment of long-term debt in 2017 and decreased income taxes and operating expenses, partially offset by a decrease in net revenues as discussed below.
For the three months ended June 30, 2018, we reported operating income of $118.4$488.2 million, or $1.31 per basic share compared to $124.0 million for the same period in 2017. The lower operating income was primarily due to decreased net revenues, attributable to a regulatory revenue reserve in 2018 resulting from the probable future refund of certain collections and new rates as a result of implementation of regulatory outcomes related to the lower income tax rate under the TCJA. These decreases were offset by increased net revenues due to weather variability between the three months ended June 30, 2018 compared to the same period in 2017, as well as from new rates from infrastructure replacement programs. Other operating expenses decreased due to lower outside service costs and employee and administrative costs, partially offset by higher depreciation expense.
On a consolidated basis, we reported net income available to common shareholders of $299.3 million, or $0.86 per basic share for the six months ended June 30, 2018, compared to $166.9 million, or $0.51 per basic share for the same period in 2017. The2018. Similar to the quarter-to-date period, the increase in net income available to common shareholders during 2019 was primarily due to lower operating expenses due to insurance recoveries recorded related to the Greater Lawrence Incident and new rates from base rate proceedings and infrastructure replacement programs. These increases were offset by an interest rate swap settlement gain in 2018 and additional dilution in 2019 resulting from preferred stock dividend commitments.
Operating Income
For the three months ended June 30, 2019, we reported operating income of $463.5 million compared to operating income of $118.4 million for the same period in 2018. As noted above, the increase in operating income was primarily due to lower operating expenses due to insurance recoveries recorded related to the Greater Lawrence Incident and new rates from base rate proceedings and infrastructure replacement programs. These increases were partially offset by increased depreciation due to regulatory outcomes of NIPSCO's gas rate case and capital expenditures being placed into service.

For the six months ended June 30, 2019, we reported operating income of $837.7 million compared to operating income of $519.0 million for the same period in 2018. The drivers for this increase were consistent with that of the quarter-to-date period.
Other Deductions, net
Other deductions, net reduced income by $94.4 million in the second quarter of 2019 compared to a reduction in income of $88.4 million in the prior year. This change is primarily due to lower actuarial investment returns on pension and other postretirement benefit assets in 2019 of $9.2 million and higher interest expense of $5.4 million in 2019 driven by decreased regulatory deferrals from Columbia of Ohio's CEP. These variances were partially offset by a loss on early extinguishment of long-term debt of $12.5 million which was recorded in 2017 and decreased income taxes and operating expenses partially offset by a decrease in net revenues as discussed below.
For the six months ended June 30, 2018, we reported operating incomesecond quarter of $519.0 million compared to $539.4 million for the same period in 2017. The lower operating income was primarily due to decreased net revenues, attributable to a regulatory revenue reserve in 2018 resulting from the probable future refund of certain collections and new rates as a result of implementation of regulatory outcomes related to the lower income tax rate under the TCJA. These decreases were offset by increased net revenues due to weather variability between the six months ended June 30, 2018 compared to the same period in 2017, as well as from new rates from infrastructure replacement programs. Other operating expenses decreased due to lower outside service and materials and supplies costs, partially offset by higher depreciation expense.2018.

Income Taxes
On December 22, 2017, the President signed into law the TCJA, which, among other things, enacted significant changes to the Internal Revenue Code of 1986, as amended, including a reduction in the maximum U.S. federal corporate income tax rate from 35% to 21%, and certain other provisions related specifically to the public utility industry, including the continuation of certain interest expense deductibility and excluding 100% expensing of capital investments. These changes were effective January 1, 2018.
The decreaseincrease in income tax expense from 20172018 to 20182019 is primarily attributable to the decreaseincreased income before income taxes in the federal corporate incomesecond quarter of 2019, as well as a higher effective tax rate andin 2019 due to the effectrelative impact of amortizing the regulatory liability associated with excess deferredpermanent differences on higher estimated pre-tax income taxes.in 2019 compared to 2018.

For the six months ended June 30, 2018,2019, we invested $832.5$843.5 million in capital expenditures across our gas and electric utilities. These expenditures were primarily aimed at furthering the safety and reliability of our gas distribution system construction of new electric transmission assets and maintaining our existing electric generation fleet.
We continue to execute on an estimated $30 billion in total projected long-term regulated utility infrastructure investments and expect to invest a total of approximately $1.7$1.6 to $1.8$1.7 billion in capital during 20182019 to continue to modernize and improve our system across all seven states.

Liquidity
As discussed in further detail below in "Liquidity and Capital Resources," theThe enactment of the TCJA has and will continue to have an unfavorable impact on our liquidity in 2018;2019; however, through income generated from operating activities, amounts available under our short-term revolving credit facility, commercial paper program, accounts receivable securitization facilities, term loan borrowings, long-term debt agreements and our ability to access the capital markets, we believe there is adequate capital available to fund our operating activities, and capital expenditures and the effects of the Greater Lawrence Incident in 20182019 and beyond. AtAs of June 30, 20182019 and December 31, 2017,2018, we had $2,228.0$952.5 million and $998.9$974.6 million, respectively, of net liquidity available, consisting of cash and available capacity under credit facilities.
These factors and other impacts to the financial results are discussed in more detail within the following discussions of “Results and Discussion of Segment Operations” and “Liquidity and Capital Resources.”
Regulatory Developments
During the quarter ended June 30, 2018,2019, we continued to move forward on core infrastructure and environmental investment programs supported by complementary regulatory and customer initiatives across all seven states of our operating area. The discussion below summarizes significant regulatory developments that transpired during the second quarter of 2018:
Gas Distribution Operations
NIPSCO is awaiting an order on the settlement with parties on its base rate case pending before the IURC. The request, which seeks NIPSCO's first natural gas base rate increase in more than 25 years, supports continued investment in system upgrades, technology improvements and other measures to increase pipeline safety and system reliability. If the settlement is approved as filed, it will result in an annual revenue increase of $107.3 million, inclusive of amounts being recovered through various tracker programs and reflecting the impact of the TCJA. An order is expected from the IURC in the third quarter of 2018.
NIPSCO's application for a new seven-year gas infrastructure modernization program remains pending before the IURC. The filing represents approximately $1.25 billion of gas infrastructure investments through 2025. The program allows for modernization of underground natural gas infrastructure and recovery of associated costs through the TDSIC. An

IURC order on the new seven-year plan is expected in the fourth quarter of 2018. On July 18, 2018, NIPSCO filed its latest revised TDSIC-8, covering approximately $54 million of investments made in the second half of 2017. This request remains pending before the IURC with an order expected the third quarter of 2018.
Columbia of Pennsylvania's base rate case remains pending before the Pennsylvania PUC. Filed on March 16, 2018, the request seeks approval for an annual revenue increase of $46.9 million to upgrade and replace the underground natural gas distribution pipelines and enhance pipeline safety. An order is expected in the fourth quarter of 2018 with new rates to be implemented in December 2018.
On April 25, 2018, the PUCO approved Columbia of Ohio’s annual IRP tracker adjustment. The order allowed recovery to begin on approximately $207 million of infrastructure investments made in 2017 with the May 2018 billing cycle. This well-established pipeline replacement program covers replacement of priority mainline pipe and targeted customer service lines.
Columbia of Massachusetts' base rate case remains pending before the Massachusetts DPU. The request, filed April 13, 2018, seeks authorization to increase base rates to recover operating costs associated with federal and state regulatory mandates and capital costs associated with upgrading its gas distribution infrastructure. If approved as filed, the request would increase annual revenues by $24.1 million, net of infrastructure trackers and impacts of the TCJA. If approved, rates are expected to go into effect March 1, 2019.
Also at Columbia of Massachusetts, the Massachusetts DPU approved the 2018 GSEP on April 30, 2018. This approval authorizes recovery of incremental capital investments of $83.9 million. New rates were effective May 1, 2018.
On July 31, 2018, Columbia of Maryland filed a settlement in its base rate case pending before the Maryland PSC. If approved as filed, the settlement would result in an annual revenue increase of $3.7 million. A Maryland PSC order is expected in the fourth quarter of 2018.
Electric Operations
NIPSCO continues to execute on its seven-year electric infrastructure modernization program, which includes enhancements to its electric transmission and distribution system designed to further improve system safety and reliability. The IURC-approved program represents approximately $1.25 billion of electric infrastructure investments expected to be made through 2022. On January 30, 2018, NIPSCO filed its latest tracker update request, covering $75.0 million in incremental investments made from May 2017 through November 2017. The filing was approved by the IURC on May 30, 2018 with rates in effect with the first billing cycle of June 2018. NIPSCO filed its latest update request on July 31, 2018 seeking a semi-annual incremental rate decrease of $10.6 million, due primarily to the pass-back to customers of a $14.1 million base rate refund for the January through May 2018 period related to the TCJA. An order approving the request is expected in the fourth quarter of 2018.
NIPSCO's two major transmission projects were completed and placed into service in June 2018. The 100-mile 345-kV and 65-mile 765-kV projects are expected to enhance region-wide system flexibility and reliability, and represent an investment of approximately $600 million.

Gas Distribution Operations










Comparability of line item operating results may be impacted by regulatory, tax and depreciation trackers (other than those for cost of sales) that allow for the recovery in rates of certain costs. Therefore, increases in these tracked operating expenses are generally offset by increases in net revenues and have essentially no impact on net income.
Three months endedMonths Ended June 30, 20182019 vs. June 30, 20172018 Operating Income
For the three months ended June 30, 2018,2019, Gas Distribution Operations reported operating income of $39.1$379.0 million, a decreasean increase of $4.6$339.9 million from the comparable 20172018 period.
Net revenues for the three months ended June 30, 20182019 were $407.5$470.4 million, an increase of $2.6$62.9 million from the same period in 2017.2018. The change in net revenues was primarily driven by:
The effects of colder weather in 2018 of $10.3 million.
New rates from base rate proceedings and infrastructure replacement programs of $8.5 million.
The effects of increased customer usage and growth of $5.3$65.6 million.
Higher regulatory, tax and depreciation trackers, which are offset in operating expense, of $2.9$7.4 million.
Partially offset by:

This weather adjustment is partially offset by a favorable variance of $3.9 million resulting from an update in the TCJA of $6.4 million.weather-related normal heating degree day methodology (discussed below).

Operating expenses were $7.2$277.0 million higherlower for the three months ended June 30, 20182019 compared to the same period in 2017.2018. This change was primarily driven by:
Insurance recoveries recorded, net of third-party claims and other expenses recorded, related to the Greater Lawrence Incident of $331.9 million.
Partially offset by:
Increased depreciation of $5.1$27.6 million due to regulatory outcomes of NIPSCO's gas rate case and higher capital expenditures placed in service.
Increased employee and administrative expenses of $9.7 million.
Higher regulatory, tax and depreciation trackers, which are offset in net revenues, of $7.4 million.
Increased property taxes of $4.7 million due to higher capital expenditures placed in service and increased amortization of property taxes previously deferred as a regulatory asset.
Six Months Ended June 30, 2019 vs. June 30, 2018 Operating Income
For the six months ended June 30, 2019, Gas Distribution Operations reported operating income of $654.4 million, an increase of $293.6 million from the comparable 2018 period.
Net revenues for the six months ended June 30, 2019 were $1,362.4 million, an increase of $216.1 million from the same period in 2018. The change in net revenues was primarily driven by:

Increased residential and commercial customer growth of $7.2 million.
Higher revenues of $8.6 million resulting from an update in the weather-related normal heating degree day methodology (see further detail below), partially offset by a $3.7 million revenue decrease from the effects of warmer weather in 2019.
Operating expenses were $77.5 million lower for the six months ended June 30, 2019 compared to the same period in 2018. This change was primarily driven by:

Weather
In general, we calculate the weather-related revenue variance based on changing customer demand driven by weather variance from normal heating degree days. Our composite heating degree days reported do not directly correlate to the weather-related dollar impact on the results of Gas Distribution Operations. Heating degree days experienced during different times of the year or in different operating locations may have more or less impact on volume and dollars depending on when and where they occur. When the detailed results are combined for reporting, there may be weather-related dollar impacts on operations when there is not an apparent or significant change in our aggregated composite heating degree day comparison.

The definition of “normal” weather was updated during the first quarter of 2019 to reflect more current weather pattern data and more closely align with the regulators' jurisdictional definitions of “normal” weather. Impacts of the change in methodology will be reflected prospectively and disclosed to the extent it results in notable year-over-year variances in net revenues.
Weather in the Gas Distribution Operations service territories for the second quarter of 20182019 was about 4% colder11% warmer than normal and about 37% colder20% warmer than 2017,2018, leading to increaseddecreased net revenues of $10.3$4.9 million for the quarter ended June 30, 20182019 compared to the same period in 2017.2018 in total. The change in weather-related net revenues was primarily driven by:
The effects of warmer weather in 2019 of $8.8 million.
Offset by:
An update in the weather-related normal heating degree day methodology resulting in a favorable variance of $3.9 million, as discussed above.
Weather in the Gas Distribution Operations service territories for the six months ended June 30, 20182019 was about 1% warmer than normal and about 22% colder1% warmer than 2018. Due to the change in 2017, leading to increasedmethodology, net revenues of $34.9increased by $4.9 million for the six months ended June 30, 20182019 compared to the same period in 2017.2018. The change in weather-related net revenues was primarily driven by:

Economic Conditions
All of our Gas Distribution Operations companies have state-approved recovery mechanisms that provide a means for full recovery of prudently incurred gas costs. Gas costs are treated as pass-through costs and have no impact on the net revenues recorded in the period. The gas costs included in revenues are matched with the gas cost expense recorded in the period and the difference is

Comparability of line item operating results may be impacted by regulatory and depreciation trackers (other than those for cost of sales) that allow for the recovery in rates of certain costs. Therefore, increases in these tracked operating expenses are offset by increases in net revenues and have essentially no impact on net income.
Three months endedMonths Ended June 30, 20182019 vs. June 30, 20172018 Operating Income
For the three months ended June 30, 2018,2019, Electric Operations reported operating income of $82.4$85.7 million, a decreasean increase of $3.2$3.3 million from the comparable 20172018 period.

LowerIncreased rates on incremental capital spend on infrastructure replacement programs and electric transmission projects of $7.2 million.
Higher regulatory and depreciation trackers, which are offset in operating expense, of $11.0 million.
Decreased rates from implementation of regulatory outcomes related to the TCJA of $8.6$3.1 million.
Lower industrial and commercial usagefuel handling costs of $6.8 million.
A regulatory revenue reserve in 2018 resulting from the probable future refund of certain collections from customers as a result of the lower income tax rate from the TCJA of $3.8$1.8 million.

Weather
In general, we calculate the weather-related revenue variance based on changing customer demand driven by weather variance from normal heating or cooling degree days. Our composite heating or cooling degree days reported do not directly correlate to the weather-related dollar impact on the results of Electric Operations. Heating or cooling degree days experienced during different times of the year may have more or less impact on volume and dollars depending on when they occur. When the detailed results are combined for reporting, there may be weather-related dollar impacts on operations when there is not an apparent or significant change in our aggregated composite heating or cooling degree day comparison.
The definition of “normal” weather was updated during the first quarter of 2019 to reflect more current weather pattern data and more closely align with the regulators' jurisdictional definitions of “normal” weather. Impacts of the change in methodology will be reflected prospectively and disclosed to the extent it results in notable year-over-year variances in net revenues.
Weather in the Electric Operations’ territories for the second quarter of 20182019 was about 71% warmer9% cooler than normal and about 48% warmer43% cooler than in 2017,2018, resulting in increaseddecreased net revenues of $6.5$8.5 million for the quarter ended June 30, 20182019 compared to the same period in 2017.2018.

Sales
Electric Operations sales for the second quarter of 20182019 were 4,085.93,812.0 gwh, a decrease of 85.4273.9 gwh compared to the same period in 2017.2018. This decrease was primarily attributable to the effects of cooler weather on residential and commercial customers and higher internal generation from large industrial customers during the second quarter of 2019.
Electric Operations sales for the six months ended June 30, 20182019 were 8,197.87,755.5 gwh, a decrease of 38.0442.3 gwh compared to the same period in 2017.2018. The drivers for this decrease are consistent with the quarter-to-date period.
BP Products North America. AmericaOn March 29, 2018, WCE, which is currently owned by BP p.l.c ("BP") and BP Products North America, which operates the BP Refinery, filed a petition at the IURC asking that the combined operations of WCE and BP be treated as a single premise, and the WCE generation be dedicated primarily to BP Refinery operations beginning in May 2019 as WCE has self-certified as a qualifying facility at FERC. BP Refinery plansplanned to continue to purchase electric service from NIPSCO at a reduced demand level beginning in May 2019, however a settlement agreement was filed on November 2, 2018 agreeing that BP and WCE would not move forward with construction of a private transmission line to serve BP until conclusion of NIPSCO’s pending electric rate case. The IURC approved the settlement agreement as filed on February 20, 2019. Refer to Note 8,7, "Regulatory Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited) for additional information.
Economic Conditions
NIPSCO has a state-approved recovery mechanism that provides a means for full recovery of prudently incurred fuel costs. Fuel costs are treated as pass-through costs and have no impact on the net revenues recorded in the period. The fuel costs included in revenues are matched with the fuel cost expense recorded in the period and the difference is recorded on the Condensed Consolidated Balance Sheets (unaudited) as under-recovered or over-recovered fuel cost to be included in future customer billings.
Electric Supply
NIPSCO 20162018 Integrated Resource Plan. On February 1,Multiple factors, but primarily economic ones, including low natural gas prices, advancing cost effective renewable technology and increasing capital and operating costs associated with existing coal plants, have led NIPSCO to conclude in its October 2018 as previously approved byIntegrated Resource Plan submission that NIPSCO’s current fleet of coal generation facilities will be retired earlier than previous Integrated Resource Plan’s had indicated.

Liquidity and Capital Resources
Greater Lawrence Incident: As discussed in "Executive Summary" and Note 17, “Other Commitments and Contingencies,” we have recorded losses associated with the Greater Lawrence Incident and have invested capital to replace the entire affected 45-mile cast iron and bare steel pipeline system that delivers gas to the impacted area. As discussed in the Executive Summary and Note 17 referenced earlier in this paragraph, we expect to incur additional expenses and liabilities in excess of our recorded liabilities and estimated additional costs associated with the Greater Lawrence Incident. The timing and amount of future financing needs will depend on the ultimate timing and amount of payments made to third parties in connection with the Greater Lawrence Incident and the timing and amount of associated insurance recoveries. Since the Greater Lawrence Incident and through June 30, 2019, we have collected $410 million from insurance providers which has aided liquidity. As of June 30, 2019, we have a recorded insurance receivable balance of $260 million. Insurance proceeds in the amount of $125 million were received subsequent to the June 30, 2019 balance sheet date. We expect to collect the remainder of the recorded insurance receivable balance by the end of 2019.
Through income generated from operating activities, amounts available under our short-term revolving credit facility, commercial paper program, accounts receivable securitization facilities, term loan borrowings, long-term debt agreements and our ability to access the capital markets, we believe there is adequate capital available to fund these expenditures.
Operating Activities
Net cash from operating activities for the six months ended June 30, 20182019 was $809.5$926.2 million, an increase of $158.1$116.7 million compared to the six months ended June 30, 2017.2018. This increase was driven by changes in gas prices, which impacted regulatory assetsinsurance recoveries related to the Greater Lawrence Incident, partially offset by related cash payments for claims and regulatory liabilities as discussed further below. Additionally, cash from operations increased as a result of lower operations and maintenance spend in the current year, higher sales due to colder weather during the winter heating season and increased rates from infrastructure replacement programs.
Regulatory Assets and Liabilities.other expenses. For the six months ended June 30, 2018 the source2019, we received approximately $108 million of cashinsurance recoveries, net of payments for expenses, related to regulatory assets and liabilities is primarily attributablethe Greater Lawrence Incident. Refer to the over-collection of gas costs which resulted from decreasing gas prices during the period.
Income Taxes. Rates for our regulated customers include provisions for the collection of U.S. federal income taxes. The reductionNote 17-D "Other Matters" in the U.S. federal corporate income tax rate as a result of the TCJA has, and is expectedNotes to continue to lead to a decrease in the amount billed to customers through rates, ultimately resulting in lower cash collections from operating activities. As discussed in further detail in Note 8, "Regulatory Matters," our regulated subsidiaries are engaged with the relevant state utility commissions to address the impacts of the TCJA on future customer rates. Through the first six months of 2018, billings to customers decreased approximately $15 million compared to the same period in 2017 as a result of adjustments to certain rates in our Kentucky, Ohio, Maryland and Indiana jurisdictions. Additionally, during the first half of 2018, we recorded additional TCJA-related regulatory liabilities of $65.0 million related to 2018 collections from customers, which we believe are probable of being refunded back to customers once new customer rates are approved by our regulators.
In addition, we will be required to pass back to customers “excess deferred taxes,” which represent amounts collected from customers in the past to cover deferred tax liabilities that, as a result of the passage of the TCJA, are now expected to be less than the originally billed amounts. Approximately $1.5 billion of excess deferred taxes related to implementation of the TCJA were recorded within "Regulatory liabilities (noncurrent)" on the Condensed Consolidated Balance SheetsFinancial Statements (unaudited) as of December 31, 2017. The majority of these balances relate to temporary book-to-tax differences on utility property protected by IRS normalization rules. Once modified rates are approved by our regulators, we expect this portion of the balances will be passed back to customers over the remaining average useful life of the associated property. The pass back period for the remainder of the balance will be determined by our state utility commissions in future proceedings. Our estimate of the amount and pass-back period of excess deferred taxes is subject to change pending final review by the utility commissions of the states in which we operate.
As of June 30, 2018, we had a recorded deferred tax asset of $493.5 million related to a Federal NOL carryforward. As a result of being in an NOL position, we were not required to make any cash payments for Federal income tax purposes during the six months ended June 30, 2018 or 2017. This NOL carryforward expires in 2030; however, we expect to fully utilize the carryforward benefit prior to its expiration.further information.
Investing Activities
Net cash used for investing activities for the six months ended June 30, 20182019 was $871.1$898.0 million, an increase of $85.2$26.9 million compared to the six months ended June 30, 2017.2018. This increase was mostly attributable to increasedhigher cost of removal expenditures and higher capital expenditures in 2019.
Our cost of removal expenditures for the six months ended June 30, 2019 were $55.7 million compared to $46.1 million for the comparable period in 2018. The increase was driven by additional cost of removal projects completed at our Michigan City generating station.
Our capital expenditures for the six months ended June 30, 20182019 were $832.5$843.5 million compared to $732.2$832.5 million for the comparable period in 2017.2018. The increase in capital spend was driven by an increaseadditional capital spending related to the Greater Lawrence Incident, partially offset by a decrease in planned capital expenditures inspending at NIPSCO related to the current yearconclusion of electric transmission and the timing of payments through June 2018 compared to June 2017.CCR projects. We project total 20182019 capital expenditures to be approximately $1.7$1.6 to $1.8$1.7 billion.

Certain of our subsidiaries have agreements that contain “ratings triggers” that require increased collateral if our credit rating or the credit ratings of certain of our subsidiaries are below investment grade. These agreements are primarily for insurance purposes and for the physical purchase or sale of power. As of June 30, 2018,2019, the collateral requirement that would be required in the event of a downgrade below the ratings trigger levels would amount to approximately $52.9$64.7 million. In addition to agreements with ratings triggers, there are other agreements that contain “adequate assurance” or “material adverse change” provisions that could necessitate additional credit support such as letters of credit and cash collateral to transact business.

Market Risk Disclosures
Risk is an inherent part of our businesses. The extent to which we properly and effectively identify, assess, monitor and manage each of the various types of risk involved in our businesses is critical to our profitability. We seek to identify, assess, monitor and manage, in accordance with defined policies and procedures, the following principal market risks that are involved in our businesses: commodity price risk, interest rate risk and credit risk. Risk management for us is a multi-faceted process with oversight by the Risk Management Committee that requires constant communication, judgment and knowledge of specialized products and markets. Our senior management takes an active role in the risk management process and has developed policies and procedures that require specific administrative and business functions to assist in the identification, assessment and control of various risks. These may include, but are not limited to market, operational, financial, compliance and strategic risk types. In recognition of the increasingly varied and complex nature of the energy business, our risk management process, policies and procedures continue to evolve and are subject to ongoing review and modification.
Commodity Price Risk
We are exposed to commodity price risk as a result of our subsidiaries’ operations involving natural gas and power. To manage this market risk, our subsidiaries use derivatives, including commodity futures contracts, swaps, forwards and options. We do not participate in speculative energy trading activity.
Commodity price risk resulting from derivative activities at our rate-regulated subsidiaries is limited, since regulations allow recovery of prudently incurred purchased power, fuel and gas costs through the ratemaking process, including gains or losses on these derivative instruments. If states should explore additional regulatory reform, these subsidiaries may begin providing services without the benefit of the traditional ratemaking process and may be more exposed to commodity price risk.
Our subsidiaries are required to make cash margin deposits with their brokers to cover actual and potential losses in the value of outstanding exchange traded derivative contracts. The amount of these deposits, some of which is reflected in our restricted cash balance, may fluctuate significantly during periods of high volatility in the energy commodity markets.
Refer to Note 9,8, "Risk Management Activities," in the Notes to Condensed Consolidated Financial Statements (unaudited) for further information on our commodity price risk assets and liabilities as of June 30, 20182019 or December 31, 2017.2018.
Interest Rate Risk
We are exposed to interest rate risk as a result of changes in interest rates on borrowings under our revolving credit agreement, commercial paper program, accounts receivable programs and term loan, which have interest rates that are indexed to short-term market interest rates. Based upon average borrowings and debt obligations subject to fluctuations in short-term market interest rates, an increase (or decrease) in short-term interest rates of 100 basis points (1%) would have increased (or decreased) interest expense by $2.9$5.1 million and $5.9$10.0 million for the three and six months ended June 30, 2018,2019, and $4.1$2.9 million and $8.9$5.9 million for the three and six months ended June 30, 2017,2018, respectively. We are also exposed to interest rate risk as a result of changes in benchmark rates that can influence the interest rates of future debt issuances.
Refer to Note 9,8, "Risk Management Activities," in the Notes to Condensed Consolidated Financial Statements (unaudited) for further information on our interest rate risk assets and liabilities as of June 30, 20182019 and December 31, 2017.2018.

Credit Risk
Due to the nature of the industry, credit risk is embedded in many of our business activities. Our extension of credit is governed by a Corporate Credit Risk Policy. In addition, Risk Management Committee guidelines are in place which document management approval levels for credit limits, evaluation of creditworthiness, and credit risk mitigation efforts. Exposures to credit risks are monitored by the risk management function which is independent of commercial operations. Credit risk arises due to the possibility that a customer, supplier or counterparty will not be able or willing to fulfill its obligations on a transaction on or before the settlement date. For derivative-related contracts, credit risk arises when counterparties are obligated to deliver or purchase defined commodity units of gas or power to us at a future date per execution of contractual terms and conditions. Exposure to credit risk is measured in terms of both current obligations and the market value of forward positions net of any posted collateral such as cash and letters of credit.
