Note regarding forward-looking statements

This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Investors and prospective investors should understand that many factors govern whether any forward-looking statement contained herein will be or can be realized. Any one of those factors could cause actual results to differ materially from those projected. These forward-looking statements include, but are not limited to, statements concerning our plans, strategies, objectives, expected performance, expenditures, recovery of expenditures through rates, stated on either a consolidated or segment basis, and any and all underlying assumptions and other statements that are other than statements of historical fact. All forward-looking statements are based on assumptions that management believes to be reasonable; however, there can be no assurance that actual results will not differ materially.

Factors that could cause actual results to differ materially from the projections, forecasts, estimates and expectations discussed in this Quarterly Report on Form 10-Q include, among other things, our debt obligations; any changes to our credit rating or the credit rating of certain of our subsidiaries; our ability to execute our growth strategy; changes in general economic, capital and commodity market conditions; pension funding obligations; economic regulation and the impact of regulatory rate reviews; our ability to obtain expected financial or regulatory outcomes; our ability to adapt to, and manage costs related to, advances in technology; any changes in our assumptions regarding the financial implications of the Greater Lawrence Incident; compliance with the agreements entered into with the U.S. Attorney’s Office to settle the U.S. Attorney’s Office’s investigation relating to the Greater Lawrence Incident; potential incidents and other operating risks associated with our business; continuing and potential future impacts from the COVID-19 pandemic; our ability to obtain sufficient insurance coverage and whether such coverage will protect us against significant losses; the outcome of legal and regulatory proceedings, investigations, incidents, claims and litigation; any damage to our reputation, including in connection with the Greater Lawrence Incident; compliance with applicable laws, regulations and tariffs; compliance with environmental laws and the costs of associated liabilities;

fluctuations in demand from residential, commercial and industrial customers; economic conditions of certain industries; the success of NIPSCO's electric generation strategy; the price of energy commodities and related transportation costs; the reliability of customers and suppliers to fulfill their payment and contractual obligations; potential impairment of goodwill; changes in taxation and accounting principles; the impact of an aging infrastructure; the impact of climate change; potential cyber-attacks; construction risks and natural gas costs and supply risks; extreme weather conditions; the attraction and retention of a qualified workforce; the ability of our subsidiaries to generate cash; our ability to manage new initiatives and organizational changes; the performance of third-party suppliers and service providers; changes in the method for determining LIBOR and the potential replacement of the LIBOR benchmark interest rate; and other matters in the “Risk Factors” section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, and in our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2020, many of which risks are beyond our control. In addition, the relative contributions to profitability by each business segment, and the assumptions underlying the forward-looking statements relating thereto, may change over time.

All forward-looking statements are expressly qualified in their entirety by the foregoing cautionary statements. We undertake no obligation to, and expressly disclaim any such obligation to, update or revise any forward-looking statements to reflect changed assumptions, the occurrence of anticipated or unanticipated events or changes to the future results over time or otherwise, except as required by law.

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, 2019. 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 Report on Form 10-Q are adequate to make the information herein not misleading.

We continue to monitor how COVID-19 is affecting our workforce, customers, suppliers, operations, financial results and cash flow. The extent of the impact in the future will vary and depend on the duration and severity of the impact on the global, national and local economies. See Note 3, “Revenue Recognition,” Note 9, “Regulatory Matters,” and Note 14, “Income Taxes,” for information on COVID-19.

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:


Standard	Description	Effective Date	Effect 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	This 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 have held discussions with our third-party specialist and identified the disclosure requirements that will impact our Notes to Condensed Consolidated Financial Statements (unaudited). We will adopt this ASU on its effective date.
ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes	This pronouncement simplifies the accounting for income taxes by eliminating certain exceptions to the general principles in ASC 740, income taxes. It also improves consistency of application for other areas of the guidance by clarifying and amending existing guidance.	Annual periods beginning after December 15, 2020 Early adoption is permitted.	We have evaluated the amendments of this pronouncement and determined it does not have an impact on the Condensed Consolidated Financial Statements (unaudited) and Notes to Condensed Consolidated Financial Statements (unaudited). We continue to monitor the guidance as it relates to new activity or transactions that could impact our Condensed Consolidated Financial Statements (unaudited) and Notes to Condensed Consolidated Financial Statements (unaudited). We expect to adopt this ASU on its effective date.
ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Statements	This pronouncement provides temporary optional expedients and exceptions for applying GAAP principles to contract modifications and hedging relationships to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates.	Upon issuance on March 12, 2020, and will apply though December 31, 2022.	We continue to evaluate the temporary expedients and options available under this guidance, and the effects of this pronouncement on our Condensed Consolidated Financial Statements (unaudited) and Notes to Condensed Consolidated Financial Statements (unaudited). We are currently identifying and evaluating contracts that may be impacted. As of September 30, 2020, we have not applied any expedients and options available under this ASU.

Standard	Description	Effective Date	Effect on the financial statements or other significant matters
ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivative and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity	This pronouncement simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity's own equity. Specifically, the ASU "simplifies accounting for convertible instruments by removing major separation models required under current GAAP." In addition, the ASU "removes certain settlement conditions that are required for equity contracts to qualify for it" and "simplifies the diluted earnings per share (EPS) calculations in certain areas."	Annual period beginning after December 15, 2021. Early adoption is permitted for annual period beginning after December 15, 2020.	This pronouncement does not impact any securities we currently have on our balance sheet. We will continue to evaluate the effects of this pronouncement on our Condensed Consolidated Financial Statements (unaudited) and Notes to Condensed Consolidated Financial Statements (unaudited) as it pertains to any relevant future activity. We are currently evaluating the timing of our adoption of this ASU.

Recently Adopted Accounting Pronouncements


Standard			Adoption
ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments			In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (ASC 326). ASC 326 revised the GAAP guidance on the impairment of most financial assets and certain other instruments that are not measured at fair value through net income. ASC 326 introduces the current expected credit loss (CECL) model that is based on expected losses for instruments measured at amortized cost rather than incurred losses. It also requires entities to record an allowance 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 debt securities will be recognized immediately in earnings, instead of over-time as they would under historic guidance. In 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivative and Hedging, and Topic 825, Financial Instruments. This pronouncement clarified and improved certain areas of guidance related to the recently issued standards on credit losses, hedging, and recognition and measurement. We adopted ASC 326 effective January 1, 2020, using a modified retrospective method. Adoption of this standard did not have material impact on our Condensed Consolidated Financial Statements (unaudited). No adjustments were made to the January 1, 2020 opening balances as a result of this adoption. As required under the modified retrospective method of adoption, results for the reporting periods beginning after January 1, 2020 are presented under ASC 326, while prior period amounts are not adjusted. See Note 3, "Revenue Recognition," and Note 11, "Fair Value," for our discussion of the implementing these standards.
ASU 2016-13, Financial Instruments-Credit Losses (Topic 326)

3. Revenue Recognition

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 sale of the Massachusetts Business was completed on October 9, 2020. Refer to Note 6, "Assets and Liabilities Held for Sale," for further details. 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 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 nine months ended September 30, 2020 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. We maintain common utility credit risk mitigation practices, including requiring deposits and actively pursuing collection of past due amounts. Our regulated operations also utilize certain regulatory mechanisms that facilitate recovery of bad debt costs within tariff-based rates, which provides further evidence of collectibility. In connection with COVID-19, certain state regulatory commissions instituted regulatory moratoriums that impacted our ability to pursue our standard credit risk mitigation practices. Following the issuance of these moratoriums, certain of our regulated operations have been authorized to recognize a regulatory asset for bad debt costs above levels currently in rates. While several of these moratoriums remain in place, we have reinstated our common credit mitigation practices where moratoriums have expired (see Note 9, "Regulatory Matters," for additional information on regulatory moratoriums and regulatory assets). It is probable that substantially all of the consideration to which we are entitled from customers will be collected upon satisfaction of performance obligations.

Allowance for Credit Losses. We adopted ASC 326 effective January 1, 2020. See "Recently Adopted Accounting Pronouncements" in Note 2, "Recent Accounting Pronouncements," for more information about ASC 326.

Each of our business segments pool their customer accounts receivables based on similar risk characteristics, such as customer type, geography, payment terms, and related macro-economic risks. Expected credit loss exposure is evaluated separately for each of our accounts receivable pools. Expected credit losses are established using a model that considers historical collections experience, current information, and reasonable and supportable forecasts. Relevant and reliable internal and external inputs used in the model include, but are not limited to, energy consumption trends, revenue projections, actual charge-offs data, recoveries data, shut-off orders executed data, and final bill data. We continuously evaluate available reasonable and supportable information relevant to assessing collectability of current and future receivables. We evaluate creditworthiness of specific customers periodically or when required by changes in facts and circumstances. When we become aware of a specific commercial or industrial customer's inability to pay, an allowance for expected credit losses is recorded for the relevant amount. We also monitor other circumstances that could affect our overall expected credit losses; these include, but are not limited to, creditworthiness of overall population in service territories, adverse conditions impacting an industry sector, and current economic conditions.

At each reporting period, we record expected credit losses using an allowance for credit losses account. When deemed to be uncollectible, customer accounts are written-off. A rollforward of our allowance for credit losses for the three and nine months ended September 30, 2020 are presented in the tables below:


Three Months Ended September 30, 2020 (in millions)	Gas Distribution Operations		Electric Operations		Corporate and Other		Total
Beginning balance	$	25.4	$	5.2	$	0.8	$	31.4
Current period provisions	8.2		2.3		—		10.5
Write-offs charged against allowance	(4.3)		(0.5)		—		(4.8)
Recoveries of amounts previously written off	2.2		—		—		2.2
Ending balance of the allowance for credit losses	$	31.5	$	7.0	$	0.8	$	39.3


Nine Months Ended September 30, 2020 (in millions)	Gas Distribution Operations		Electric Operations		Corporate and Other		Total
Beginning balance(1)	9.1		3.1		0.8		13.0
Current period provisions	30.6		6.7		—		37.3
Write-offs charged against allowance	(18.1)		(3.0)		—		(21.1)
Recoveries of amounts previously written off	9.9		0.2		—		10.1
Ending balance of the allowance for credit losses	31.5		7.0		0.8		39.3
(1)Total beginning balance differs from that presented in the Condensed Statements of Consolidated Balance Sheet (unaudited) as it excludes Columbia of Massachusetts. Columbia of Massachusetts' customer receivables and related allowance for credit losses are classified as held for sale at September 30, 2020.

As of September 30, 2020, we have also evaluated the adequacy of our allowance for credit losses in light of the suspension of shut-offs for nonpayment due to COVID-19 that remain in effect for certain jurisdictions, as well as the economic downturn. Our evaluation included an analysis of customer payment trends in 2020, economic conditions, receivables aging, and considerations of past economic downturns and corresponding allowance for credit losses and customer account write-offs. In addition, we considered benefits available under governmental COVID-19 relief programs, the impact of unemployment benefits initiatives, and flexible payment plans being offered to customers affected by or experiencing hardship as a result of COVID-19, which could help to mitigate the potential for increasing customer account delinquencies. Based upon this evaluation, we have concluded that the allowance for credit losses as of September 30, 2020 adequately reflected the collection risk and net realizable value for our receivables. We will continue to monitor changing circumstances and will adjust our allowance for credit losses as additional information becomes available.

4. Earnings Per Share

Basic EPS is computed by dividing net income (loss) available 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 and forward agreements when the impact would be dilutive. The dilutive effects of forward agreements for the nine months ended September 30, 2019 relate to forward agreements settled in the fourth quarter of 2019. The computation of diluted average common shares for the three and nine months ended September 30, 2020 and the three months ended September 30, 2019 is not presented as we had a net loss on the Condensed Statements of Consolidated Income (Loss) (unaudited) during those periods, and any incremental shares would have had an anti-dilutive impact on EPS. The computation of diluted average common shares is as follows:

5. Equity

Common Stock. As of September 30, 2020, we had 600,000,000 shares of common stock authorized for issuance, of which 383,114,130 shares were outstanding.

ATM Program and Forward Sale Agreements. On November 1, 2018, we entered into five separate equity distribution agreements pursuant to which we were able to sell up to an aggregate of $500.0 million of our common stock. Four of these agreements were then amended on August 1, 2019, and one was terminated. Pursuant to the four agreements, as amended, we may sell, from time to time, up to an aggregate of $434.4 million of our common stock.

On August 6, 2020, 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 August 7, 2020 to September 3, 2020, 2,809,029 shares were borrowed from third parties and sold by the dealer at a weighted average price of $23.25 per share. We may settle this agreement in shares, cash, or net shares by December 15, 2020. Had we settled all the shares under the forward agreement at September 30, 2020, we would have received approximately $64.6 million, based on a net price of $23.01 per share.

On September 4, 2020, under the ATM program, we executed a separate forward agreement similar to that discussed above. From September 4, 2020 to September 16, 2020, 1,452,102 shares were borrowed from third parties and sold by the dealer at a weighted average price of $22.28 per share. We may settle this agreement in shares, cash, or net shares by December 15, 2020. Had we settled all the shares under the forward agreement at September 30, 2020, we would have received approximately $32.0 million, based on a net price of $22.05 per share.

As of September 30, 2020, the ATM program (including the impacts of the forward sale agreements discussed above) had approximately $103.0 million of equity available for issuance. The program expires on December 31, 2020.

6. Assets and Liabilities Held For Sale

On February 26, 2020, NiSource and Columbia of Massachusetts entered into an Asset Purchase Agreement with Eversource (the "Asset Purchase Agreement"). Upon the terms and subject to the conditions set forth in the Asset Purchase Agreement, NiSource and Columbia of Massachusetts agreed to sell to Eversource, with certain additions and exceptions: (1) substantially all of the assets of Columbia of Massachusetts and (2) all of the assets held by any of Columbia of Massachusetts’ affiliates that primarily relate to the Massachusetts Business, and Eversource agreed to assume certain liabilities of Columbia of Massachusetts and its affiliates. The liabilities assumed by Eversource under the Asset Purchase Agreement did not include, among others, any liabilities arising out of the Greater Lawrence Incident or liabilities of Columbia of Massachusetts or its affiliates pursuant to civil claims for injury of persons or damage to property to the extent such injury or damage occurs prior to the closing in connection with the Massachusetts Business.

On July 2, 2020, NiSource, Columbia of Massachusetts, Eversource and Eversource Gas Company of Massachusetts, a wholly-owned subsidiary of Eversource (“EGMA”), filed with the Massachusetts DPU a joint petition for the approval of the purchase and sale of the Massachusetts Business ("the Transaction") and a proposed multi-year rate plan. Additionally, the petition sought approval of a settlement agreement executed on July 2, 2020 (the “Settlement Agreement”) among, NiSource, Columbia of Massachusetts, Eversource, EGMA, the Massachusetts Attorney General’s Office ("Massachusetts AGO"), the Massachusetts Department of Energy Resources ("DOER"), and the Low-Income Weatherization and Fuel Assistance Program Network. Under the terms of the Settlement Agreement, NiSource agreed to make a payment in lieu of penalties in full settlement of all of the pending and potential claims, lawsuits, investigations or proceedings settled by and released by the Settlement Agreement in the amount of $56.0 million. This payment, which was withheld from the proceeds received from Eversource, will be used to create an Energy Relief Fund that will benefit customers of the Massachusetts Business.

The Settlement Agreement was conditioned on its approval in full by the Massachusetts DPU no later than September 30, 2020; however, this deadline was extended to October 7, 2020. The Settlement Agreement was approved by the Massachusetts DPU on October 7, 2020, and the closing of the Transaction occurred on October 9, 2020. On October 9, 2020, NiSource and Columbia of Massachusetts received net proceeds from the sale of $1,112.6 million, which includes the $1,100.0 million purchase price and an estimate of Columbia of Massachusetts' net working capital, net of closing costs and the $56.0 million payment in lieu of penalties. Under the Asset Purchase Agreement, the final net working capital amount will be determined within 120 days from the closing date. In connection with the sale of the Massachusetts Business, NiSource and Eversource entered into a Transition Services Agreement (TSA). See Note 18-B, "Legal Proceedings," and Note 18-D, "Other Matters," for additional information regarding the sale and TSA, respectively.

As of September 30, 2020, the Massachusetts Business continues to meet the requirements under GAAP to be classified as held for sale, and the assets and liabilities of the Massachusetts Business are measured at fair value, less costs to sell. Our estimated

Table of Contents

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

total pre-tax loss on classification as held for sale recorded in the the three and nine months ended September 30, 2020 is $35.6 million and $400.2 million, respectively, based on September 30, 2020 asset and liability balances, estimated net working capital and estimated transaction costs, including the $56.0 million payment in lieu of penalties described above. This estimated pre-tax loss is presented as Loss on Classification as Held for Sale on the Condensed Statements of Consolidated Income (Loss) (unaudited) and is subject to change based on actual transaction costs, net working capital, and asset and liability balances as of the close of the transaction on October 9, 2020.

The Massachusetts Business had the following pretax income (loss) for the three and nine months ended September 30, 2020 and 2019:


	Three Months Ended September 30,		Nine Months Ended September 30,
(in millions)	2020	2019	2020	2019
Pretax Income (Loss)	($74.1)	($55.2)	($402.9)	$183.5

The pretax income (loss) amounts exclude allocated executive compensation expense and interest expense for intercompany and external debt that was not assumed by Eversource or required to be repaid at closing. The pretax income (loss) amounts for the three and nine months ended September 30, 2020 and 2019 include costs directly related to the Greater Lawrence Incident. In addition, the pretax loss amounts for the three and nine months ended September 30, 2020 include the Loss on Classification as Held for Sale. The major classes of assets and liabilities classified as held for sale on the Condensed Consolidated Balance Sheets (unaudited) at September 30, 2020 were:

7. Property, Plant and Equipment

In the second quarter of 2020, we received approval from MISO to retire the R.M. Schahfer Generating Station in 2023. As a result of this approval, we have reclassified $903.8 million in net book value of certain plant and equipment for the R.M. Schahfer Generating Station from “Net utility plant” to “Other Property, at cost, less accumulated depreciation” on the Condensed Consolidated Balance Sheets (unaudited). The amount of plant and equipment reclassified to other property is based on current estimates of the plant and equipment that will not be utilized at retirement. As more information about plant and equipment that can be utilized beyond 2023 becomes available, additional amounts may be reclassified to other property. Depreciation expense will continue to be recorded at the composite depreciation rate approved by the IURC. See Note 18-D, "Other Matters," for additional information.

8. Asset Retirement Obligations

During 2020, 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 $70.3 million that was recorded in 2020. See Note 18-C, "Environmental Matters," for additional information on CCRs.

9. Regulatory Matters

Cost Recovery and Trackers

Comparability of our 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 generally result in a corresponding increase in operating revenues and, therefore, have essentially no impact on total operating income results.

Certain costs of our operating companies are significant, recurring in nature and generally outside the control of the operating 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 operating 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, bad debt recovery 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 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.

A portion of the Electric Operations 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.

Infrastructure 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.

COVID-19 Regulatory Filings

In response to COVID-19, we have engaged, or have received directives from, the regulatory commissions in the states in which we operate, as described below.

Columbia of Ohio filed a Deferral Application and a Transition Plan with the PUCO on May 29, 2020. The Deferral Application requested approval to record a regulatory asset for COVID-19 incremental costs, foregone revenue from late payment fees, and bad debt expense from certain classes of customers. An order approving the Deferral Application was received on July 15, 2020. The Transition Plan requested the resumption of activities that were suspended in March 2020, including resumption of disconnects due to non-payment and billing of late payment fees beginning with the August 2020 billing cycle. The PUCO approved the Transition Plan on June 17, 2020. As of September 30, 2020, $1.9 million of incremental COVID-19 related costs were deferred to a regulatory asset. Recovery of the regulatory asset will be addressed in a future regulatory proceeding.

NIPSCO received a COVID-19 order from the IURC on June 29, 2020. This order extended the disconnection moratorium and the suspension of collection of late payment fees, deposits and reconnection fees through August 14, 2020. The order requires utilities to offer payment arrangements of at least six months and requires NIPSCO to provide the IURC with information about NIPSCO’s communications with delinquent customers. On August 12, 2020, the IURC issued an order affirming the expiration of the disconnect moratorium after August 14, 2020, while requiring that six month payment plans be offered to all customers and extending the suspension for collection of late payment fees, deposits, and reconnection fees through October 12, 2020 for residential customers only. On October 7, 2020 the Office of Utility Consumer Counselor ("OUCC") filed a motion for the IURC to extend these temporary consumer protections for an additional 60 days. On October 27, the IURC issued a docket entry denying the OUCC's motion. The June 29, 2020 order also authorized NIPSCO to create a regulatory asset for COVID-19 related incremental bad debt expense as well as the costs to implement the requirements of the order. As of September 30, 2020, $4.8 million of incremental bad debt expense and costs to implement the requirements of the order were deferred to a regulatory asset. Recovery of the regulatory asset will be addressed in future base rate proceedings.

Columbia of Pennsylvania received a secretarial letter issued by the Pennsylvania PUC on May 13, 2020 authorizing Pennsylvania utilities to create a regulatory asset for incremental bad debt expense incurred since March 13, 2020, above levels currently in rates. While Columbia of Pennsylvania is not authorized to defer any other incremental costs, it is required to track extraordinary non-recurring costs, and any offsetting benefits received, in connection with COVID-19. On October 13, 2020, the Pennsylvania PUC entered an order modifying its March 13, 2020 emergency order, which established a moratorium on utility service terminations. As modified, the moratorium still applies to residential customers with incomes at or below 300% of the federal poverty income guidelines (“protected customers”). For all other customers, the moratorium will be lifted on November 9, 2020, but utilities must comply with several notice requirements beyond those already in place in Pennsylvania in order to proceed with service terminations. For residential customers who are subject to termination under the revised moratorium, as of November 1, 2020, the standard winter service moratorium will be in effect until April 1, 2021, which will render service termination for delinquent accounts impractical during that period. The Pennsylvania PUC’s October 13, 2020 order also includes the following requirements: a utility shall offer a payment arrangement for a period of no less than 18 months to small business customers, as defined by a utility’s tariff, with past due amounts; utilities shall waive all connection,

Table of Contents

ITEM 1. FINANCIAL STATEMENTS (continued)

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

reconnection, late payment fees and deposit fees otherwise required for service for protected customers. Additionally, the October 13, 2020 order authorizes utilities to create a regulatory asset for any incremental expenses incurred above those embedded in rates resulting from the directives contained in the Order. As of September 30, 2020, $1.3 million of incremental bad debt expense was deferred to a regulatory asset. Recovery of any regulatory asset will be addressed in future base rate proceedings.

On March 16, 2020, the VSCC ordered a moratorium on service disconnections for unpaid bills due to the effects of COVID-19, which was subsequently extended through October 5, 2020 to allow the Virginia General Assembly to address the issue. The order also suspended late payment fees, required utilities to offer payment plans of up to 12 months, and required utilities to provide certain information about customer accounts receivables to the VSCC. The VSCC moratorium expired on October 6, 2020; however, the directives requiring utilities to offer payment plans of up to 12 months and suspending service disconnections or charging of late payment fees to customers that are current on such payment plans remain in effect. On October 16, 2020, the Virginia General Assembly passed legislation that would extend the moratorium on service disconnections and late payment fees; action from the Governor on the legislation is pending. Columbia of Virginia continues its suspension of service disconnections and late payment fees until the result of the pending legislation is known. Columbia of Virginia received an order from the VSCC on April 29, 2020 authorizing Columbia of Virginia to create a regulatory asset for incremental bad debt expense, suspended late payment fees, reconnection costs, carrying costs and other incremental prudently incurred costs related to COVID-19. We are evaluating the impact of the order. Recovery of any regulatory asset, when recorded, will be addressed in future base rate proceedings.

On August 31, 2020, with the Maryland governor's executive order prohibiting residential utility service terminations set to expire on September 1, 2020, the Maryland PSC issued an emergency order that prohibited residential service terminations until October 1, 2020. The Maryland PSC's August 31, 2020 emergency order also includes the following requirements: effective October 1, 2020, Maryland utilities may proceed with residential service terminations; utilities must give notice at least 45 days before terminating service on a residential account; structured payment plans offered to applicable residential customers must allow a minimum of 12 months to repay, or 24 months for certified low income customers; utilities are prohibited from collecting or requiring down payments or deposits as a condition of beginning a payment plan by any residential customer; and utilities are prohibited from refusing to negotiate or denying a payment plan to a residential customer due to such customer's failure to meet the terms and conditions of an alternate payment plan during the past 18 months. Columbia of Maryland received an order issued by the Maryland PSC on April 9, 2020, authorizing Maryland utilities to create a regulatory asset for incremental COVID-19 related costs, including incremental bad debt expense, incurred to ensure that customers have essential utility service during the state of emergency in Maryland. Such incremental costs must be offset by any benefit received in connection with COVID-19. As of September 30, 2020, Columbia of Maryland has deferred $0.5 million of incremental bad debt expense and COVID-19 related costs to a regulatory asset. Recovery of the regulatory asset will be addressed in future base rate proceedings.

Columbia of Kentucky received an order from the Kentucky PSC on September 21, 2020 lifting the disconnection moratorium for all customers, effective October 20, 2020. The September 21, 2020 order also lifted the suspension of late payment and reconnection fees for non-residential customers as of October 20, 2020. For residential customers, the moratorium on late payment and reconnection fees is extended to December 31, 2020 and tracking of lost revenue is required. Residential customers with accumulated arrearages for service provided on or after March 16, 2020 through October 1, 2020 will be notified and placed on a default payment plan of equal installments for nine months beginning with the November 2020 billing cycle. Residential customers on a payment plan that default shall be offered another payment plan. Carrying charges may be applied to all arrearages arising during the default payment plan period at a rate no greater than the utility’s long-term debt rate. The Kentucky PSC order allows Columbia of Kentucky to create a regulatory asset for carrying charges on all arrearages arising during the default payment plan period. Recovery of the regulatory asset, when recorded, will be addressed in future base rate proceedings. Columbia of Kentucky is engaged with peer utilities and is working closely with the Kentucky PSC on the implementation of the September 21, 2020 order, including exploring flexible payment plans for customers who need financial assistance in order to mitigate the amount of uncollectible customer receivables and tracking of COVID-19 related costs.

10. 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.

Risk management assets and liabilities on our derivatives are presented on the Condensed Consolidated Balance Sheets (unaudited) as shown below:

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 to certain customers 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 10 years and is limited to 20% 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 September 30, 2020, we have two forward-starting interest rate swaps with an aggregate notional value totaling $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 2024. These interest rate swaps are designated as cash flow hedges. The gains and losses related to these swaps are recorded to AOCI and will be 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 the Condensed Statements of Consolidated Income (Loss) (unaudited).

There were no amounts excluded from effectiveness testing for derivatives in cash flow hedging relationships at September 30, 2020 and December 31, 2019.

Risk Management Assets and Liabilities. 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, and 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 September 30, 2020 and December 31, 2019, 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.

Credit risk is considered in the fair value calculation of each of our forward-starting interest rate swaps, as described in Note 10, "Risk Management Activities." 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.

NIPSCO has entered into long-term forward natural gas purchase instruments 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 10, “Risk Management Activities.”

Available-for-Sale Debt Securities. Available-for-sale debt securities are investments pledged as collateral for trust accounts related to our wholly-owned insurance company. 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.

We adopted ASC 326 effective January 1, 2020. See "Recently Adopted Accounting Pronouncements" in Note 2, "Recent Accounting Pronouncements," for more information about ASC 326. Upon adoption of ASC 326, our available-for-sale debt securities impairments are recognized periodically using an allowance approach instead of an 'other than temporary' impairment model. At each reporting date, we utilize a quantitative and qualitative review process to assess the impairment of available-for-sale debt securities at the individual security level. For securities in a loss position, we evaluate our intent to sell or whether it is more-likely-than-not that we will be required to sell the security prior to the recovery of its amortized cost. If either criteria is met, the loss is recognized in earnings immediately, with the offsetting entry to the carrying value of the security. If both criteria are not met, we perform an analysis to determine whether the unrealized loss is related to credit factors. The analysis focuses on a variety of factors that include, but are not limited to, downgrade on ratings of the security, defaults in the current reporting period or projected defaults in the future, the security's yield spread over treasuries, and other relevant market data. If the unrealized loss is not related to credit factors, it is included in other comprehensive income. If the unrealized loss is related to credit factors, the loss is recognized as credit loss expense in earnings during the period, with an offsetting entry to the allowance for credit losses. The amount of the credit loss recorded to the allowance account is limited by the amount at which security's fair value is less than its amortized cost basis. If the credit losses in the allowance for credit losses are deemed uncollectible, the allowance on the uncollectible portion will be charged off, with an offsetting entry to the carrying value of the security. Subsequent improvements to the estimated credit losses of available-for-sale debt securities will be recognized immediately in earnings instead of over-time as they would under historic guidance. During the nine months ended September 30, 2020, we recorded $0.7 million as an allowance for credit losses on available-for-sale debt securities as a result of the analysis described above. Continuous credit monitoring and portfolio credit balancing mitigates our risk of credit losses on our available-for-sale debt securities.

The amortized cost, gross unrealized gains and losses, allowance for credit losses, and fair value of available-for-sale securities at September 30, 2020 and December 31, 2019 were:


September 30, 2020 (in millions)	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses(1)		Allowance for Credit Losses		Fair Value
Available-for-sale debt securities
U.S. Treasury debt securities	$	31.5	$	0.4	$	—	$	—	$	31.9
Corporate/Other debt securities	124.6		7.0		(1.0)		(0.7)		129.9

Total	$	150.1	$	4.3	$	(0.2)	$	—	$	154.2

(1)Fair value of U.S. Treasury debt securities and Corporate/Other debt securities in an unrealized loss position without an allowance for credit losses is $0 and $20.4 million, respectively, at September 30, 2020.

(2)Fair value of U.S. Treasury debt securities and Corporate/Other debt securities in an unrealized loss position without an allowance for credit losses is $17.2 million and $12.2 million, respectively, at December 31, 2019.

Realized gains and losses on available-for-sale securities were immaterial for the three and nine months ended September 30, 2020 and 2019.

The cost of maturities sold is based upon specific identification. At September 30, 2020, approximately $7.0 million of U.S. Treasury debt securities and approximately $5.8 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 as of September 30, 2020 and December 31, 2019.

Non-recurring Fair Value Measurements

We measure the fair value of certain assets on a non-recurring basis, typically annually or when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. These assets include goodwill.

As of September 30, 2020, the Massachusetts Business met the requirements under GAAP to be classified as held for sale, and the assets and liabilities of the Massachusetts Business are measured at fair value, less costs to sell. Our estimated total pre-tax loss for the three and nine months ended September 30, 2020 is $35.6 million and $400.2 million, respectively. For additional information, see Note 6, "Assets and Liabilities Held for Sale."

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. As of September 30, 2020, there was no change in the method or significant assumptions used to estimate the fair value of long-term debt.

Long-term debt (including current portion)	$	9,230.3	$	10,723.5	$	7,869.6	$	8,764.4

12. 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-party financial institutions through wholly-owned and consolidated special purpose entities. The three agreements expire between May 2021 and October 2021 and may be further extended if mutually agreed to by the parties thereto.

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 September 30, 2020, the maximum amount of debt that could be recognized related to our accounts receivable programs is $275.0 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 September 30, 2020 and December 31, 2019:


(in millions)	September 30, 2020		December 31, 2019
Gross receivables	$	421.7	$	569.1
Less: Receivables not transferred	190.5		215.9
Net receivables transferred	$	231.2	$	353.2
Short-term debt due to asset securitization	$	231.2	$	353.2

For the nine months ended September 30, 2020 and 2019, $122.0 million and $139.1 million, respectively, was recorded as cash flows used for financing activities related to the change in short-term borrowings due to securitization transactions. Fees associated with the securitization transactions were $0.6 million and $0.6 million for the three months ended September 30, 2020 and 2019, respectively and $2.1 million and $2.0 million for the nine months ended September 30, 2020 and 2019, respectively. Columbia of Ohio, NIPSCO and Columbia of Pennsylvania remain responsible for collecting on the receivables securitized, and the receivables cannot be transferred to another party.

13. Goodwill

The following presents our goodwill balance allocated by segment as of September 30, 2020:


(in millions)	Gas Distribution Operations		Electric Operations		Corporate and Other		Total
Goodwill	$	1,485.9	$	—	$	—	$	1,485.9

For our annual goodwill impairment analysis performed as of May 1, 2020, we completed a quantitative "step 1" fair value measurement of our reporting units with a goodwill balance. This analysis incorporated the latest available income statement and cash flow projections, including significant, identifiable impacts of COVID-19 on the operations of each of our goodwill reporting units. We also incorporated other significant inputs to our fair value calculations, including discount rate and market multiples, to reflect current market conditions. The step 1 analysis performed indicated that the fair value of each reporting unit that is allocated goodwill significantly exceeded its carrying value. As a result, no impairment charge was recorded as of the May 1, 2020 test date.

During the fourth quarter of 2019, in connection with the preparation of the year-end financial statements, we assessed the matters related to Columbia of Massachusetts (see Note 18-B, "Legal Proceedings") and determined a quantitative "step 1"

Table of Contents

ITEM 1. FINANCIAL STATEMENTS (continued)

NiSource Inc.

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

impairment analysis was required for our Columbia of Massachusetts reporting unit. The December 31, 2019 impairment analysis indicated that the fair value of the Columbia of Massachusetts reporting unit was below its carrying value. As a result, we reduced the Columbia of Massachusetts reporting unit goodwill balance to zero and recognized a goodwill impairment charge totaling $204.8 million in 2019.

14. Income Taxes

Our interim effective tax rates reflect the estimated annual effective tax rates for 2020 and 2019, adjusted for tax expense associated with certain discrete items. The effective tax rates for the three months ended September 30, 2020 and 2019 were 27.3% and 283.3%, respectively. The effective tax rates for the nine months ended September 30, 2020 and 2019 were 42.0% and 18.8%, respectively. These effective tax rates differ from the federal statutory tax rate of 21% primarily due to increased amortization of excess deferred federal income tax liabilities, as specified in the TCJA, tax credits, state income taxes and other permanent book-to-tax differences. These adjustments have a relative impact on the effective tax rate proportionally to pretax income or loss.

The decrease in the three month effective tax rate of 256.0% in 2020 compared to 2019 is primarily attributable to the relative impact of permanent differences on lower pre-tax loss in 2019, offset by increased amortization of excess deferred federal income tax liabilities, as specified in the TCJA, in 2020.

The increase in the nine month effective tax rate of 23.2% in 2020 compared to 2019 is primarily attributed to increased amortization of excess deferred federal income tax liabilities and lower state income taxes, offset by the non-deductible payment in lieu of penalties (see Note 6, "Assets and Liabilities Held for Sale," for additional information on the payment in lieu of penalties).

There were no material changes recorded in 2020 to our uncertain tax positions recorded as of December 31, 2019.

CARES Act Tax Matters. The CARES Act was enacted on March 27, 2020 in response to the COVID-19 pandemic. The CARES Act contains numerous income tax provisions, such as relaxing limitations on the deductibility of interest and the use of net operating losses arising in taxable years beginning after December 31, 2017. Under the provisions of the CARES Act, we have deferred payroll tax payments of approximately $21.7 million through September 30, 2020. We continue to monitor additional guidance to clarify provisions in the CARES Act (as well as under the TCJA) to determine if such guidance could ultimately increase or lessen their impact on our business and financial condition. There are no material income tax impacts on our consolidated financial position, results of operations, and cash flows during the three and nine months ended September 30, 2020.

15. 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. We determined that, for certain rate-regulated subsidiaries, the future recovery of postretirement benefit costs is probable, and we record regulatory assets and liabilities for amounts that would otherwise have been recorded to expense or accumulated other comprehensive loss. Current rates of rate-regulated companies include postretirement benefit costs, including amortization of the regulatory assets and liabilities that arose prior to inclusion of these costs in rates. For most plans, cash contributions are remitted to grantor trusts.

For the nine months ended September 30, 2020, we contributed $2.1 million to our pension plans and $16.7 million to our other postretirement benefit plans.

Total Net Periodic Benefit Cost	$	13.7	$	30.8	$	8.1	$	7.5

During the third quarter of 2020, three of our qualified pension plans met the requirement for settlement accounting. A settlement charge of $8.0 million was recorded during the third quarter of 2020. These pension plans were remeasured as a result of the settlements of all three plans, as well as the transfer of employees into and out of two qualified pension plans transferred to Eversource at the closing of the sale of the Massachusetts Business. The remeasurements led to a decrease to the net pension asset of $6.1 million, an increase to the pension benefit obligation, net of plan assets, of $0.2 million, a net decrease to regulatory assets of $1.4 million, and a net credit to accumulated other comprehensive loss of $0.2 million. Net periodic pension benefit cost for 2020 decreased by $1.4 million as a result of the interim remeasurement.

The following table provides the key assumptions that were used to calculate the pension benefit obligation and the net periodic benefit cost for the plans that triggered settlement accounting:


	September 30, 2020
Weighted-average Assumption to Determine Benefit Obligation
Discount rate	2.28	%
Weighted-average Assumptions to Determine Net Periodic Benefit Costs for the period ended
Discount rate - service cost	3.39	%
Discount rate - interest cost	2.65	%
Expected return on assets	5.20	%

16. Long-Term Debt

On April 13, 2020, we completed the issuance and sale of $1.0 billion of 3.60% senior unsecured notes maturing in 2030, which resulted in approximately $987.8 million of net proceeds after deducting commissions and expenses.

On August 18, 2020, we completed the issuance and sale of $1.25 billion of 0.95% senior unsecured notes maturing in 2025 and $750.0 million of 1.70% senior unsecured notes maturing in 2031, which resulted in approximately $1,980.4 million of net proceeds after deducting commissions and expenses.

In August 2020, we executed tender offers for $969.3 million of outstanding notes consisting of a combination of our 4.45% notes due 2021, 2.65% notes due 2022, 3.85% notes due 2023, 3.65% notes due 2023, 6.25% notes due 2040, and 5.95% notes due 2041. In August and September 2020, we redeemed $609.3 million of outstanding notes representing the remainder of our 4.45% notes due 2021, 2.65% notes due 2022, 3.85% notes due 2023, and 3.65% notes due 2023 and all of our 5.89% notes due 2025. In conjunction with the debt retired, we recorded a $231.7 million loss on early extinguishment of long-term debt, primarily attributable to early redemption premiums.

In September 2020, Columbia of Massachusetts redeemed $25.0 million of its outstanding 6.26% notes due 2028. In conjunction with the debt retired, Columbia of Massachusetts recorded an $11.7 million loss on early extinguishment of long-term debt, primarily attributable to early redemption premiums. Under the terms of the Asset Purchase Agreement, Columbia of Massachusetts’ net working capital at the closing of the sale of the Massachusetts Business was increased by 50% of the debt extinguishment costs, which was approximately $5.3 million.

17. Short-Term Borrowings

We generate short-term borrowings from our revolving credit facility, commercial paper program, accounts receivable transfer programs and term loan agreement. 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. We had no outstanding borrowings under this facility as of September 30, 2020 and December 31, 2019.

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 $307.0 million of commercial paper outstanding as of September 30, 2020 and $570.0 million of commercial paper outstanding as of December 31, 2019.

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 $231.2 million in transfers as of September 30, 2020 and $353.2 million in transfers as of December 31, 2019. Refer to Note 12, "Transfers of Financial Assets," for additional information.

On April 1, 2020, we terminated and repaid in full our existing $850.0 million term loan agreement with a syndicate of banks led by MUFG Bank, Ltd. and entered into a new $850.0 million term loan agreement with a syndicate of banks led by KeyBank National Association. Any and all outstanding borrowings under the term loan agreement are due by March 31, 2021. 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 1, 2020 with an interest rate of LIBOR plus 75 basis points. On October 14, 2020, we terminated and repaid in full our $850.0 million term loan agreement with proceeds from the sale of the Massachusetts Business.

Other than for the term loan, revolving credit facility and certain commercial paper borrowings, cash flows related to the borrowings and repayments of the items listed above are presented net in the Condensed Statements of Consolidated Cash Flows (unaudited) as their maturities are less than 90 days.

18. 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 September 30, 2020 and December 31, 2019, we had issued stand-by letters of credit of $10.2 million.

We have provided guarantees related to our future performance under BTAs for our renewable generation projects. At September 30, 2020, our guarantees for the Rosewater and Indiana Crossroads BTAs totaled $195.6 million. The amount of each guaranty will decrease upon the substantial completion of the construction of the facilities. See “- D. Other Matters - NIPSCO 2018 Integrated Resource Plan,” below for more information.

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 for approximately 7,500 gas meters, the majority of which served residences and approximately 700 of which served 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. On September 1, 2020, the Massachusetts Governor terminated the state of emergency declared following the Greater Lawrence Incident.

We have been subject to inquiries and investigations by government authorities and regulatory agencies regarding the Greater Lawrence Incident, including the Massachusetts DPU and the Massachusetts Attorney General's Office, as described below. On February 26, 2020, the Company and Columbia of Massachusetts entered into agreements with the U.S. Attorney’s Office for the District of Massachusetts to resolve the U.S. Attorney’s Office’s investigation relating to the Greater Lawrence Incident, and on July 2, 2020, the Company and Columbia of Massachusetts entered into an agreement with the Massachusetts Attorney General’s Office (among other parties) to resolve the Massachusetts investigations, as described below.

NTSB Investigation. As previously disclosed, the NTSB concluded its investigation into the Greater Lawrence Incident. We have requested closure of one remaining safety recommendation and are awaiting response from the NTSB.

Massachusetts Investigations. Under Massachusetts law, the Massachusetts DPU is authorized to investigate potential violations of pipeline safety regulations and to assess a civil penalty of up to $218,647 for a violation of federal pipeline safety regulations. A separate violation occurs for each day of violation up to $2.2 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 $20.0 million per related series of violations. Further, as a result of the declaration of emergency by the Governor, the Massachusetts DPU is authorized to investigate

Table of Contents

ITEM 1. FINANCIAL STATEMENTS (continued)

NiSource Inc.

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

potential violations of the Massachusetts DPU's operational directives during the restoration efforts and assess penalties of up to $1.0 million per violation. The Massachusetts DPU conducted investigations of Columbia of Massachusetts pursuant to these authorities and approved a Settlement Agreement resolving its investigations on October 7, 2020 (defined and further described below).

On October 25, 2019, the Massachusetts DPU issued two orders opening public investigations into Columbia of Massachusetts with respect to the Greater Lawrence Incident. The Massachusetts DPU opened the first investigation under its authority to determine compliance with federal and state pipeline safety laws and regulations, and to investigate Columbia of Massachusetts’ responsibility for and response to the Greater Lawrence Incident and its restoration efforts following the incident. The Massachusetts DPU opened the second investigation under its authority to determine whether a gas distribution company has violated established standards regarding acceptable performance for emergency preparedness and restoration of service to investigate efforts by Columbia of Massachusetts to prepare for and restore service following the Greater Lawrence Incident. These investigations were resolved by the Massachusetts DPU order dated October 7, 2020 approving the Settlement Agreement (defined and further described below).

In connection with its investigation related to the Greater Lawrence Incident, on February 4, 2020, the Massachusetts Attorney General's Office issued a request for documents primarily focused on the restoration work following the incident. This investigation was resolved by the Massachusetts DPU order dated October 7, 2020 approving the Settlement Agreement (defined and further described below).

On July 2, 2020, NiSource, Columbia of Massachusetts, Eversource and Eversource Gas Company of Massachusetts, a wholly-owned subsidiary of Eversource (“EGMA”), filed with the Massachusetts DPU a joint petition for the approval of the purchase and sale of the Massachusetts Business (the “Transaction”) as contemplated by the Asset Purchase Agreement and a proposed multi-year rate plan. The Asset Purchase Agreement provides for various closing conditions, including the receipt of the approval of the Massachusetts DPU and the final resolution or termination of all pending actions, claims and investigations, lawsuits or other legal or administrative proceedings against Columbia of Massachusetts and its affiliates under the jurisdiction of the Massachusetts DPU and all future actions, claims and investigations, lawsuits or other legal or administrative proceedings against NiSource, Columbia of Massachusetts and their affiliates relating to the Greater Lawrence Incident under the jurisdiction of the Massachusetts DPU, each as determined by NiSource in its reasonable discretion (the “DPU Required Resolution”).

The petition included and sought approval of a settlement agreement executed on July 2, 2020 (the “Settlement Agreement”) among, NiSource, Columbia of Massachusetts, Eversource, EGMA, the Massachusetts Attorney General’s Office ("Massachusetts AGO"), the Massachusetts Department of Energy Resources ("DOER"), and the Low-Income Weatherization and Fuel Assistance Program Network (together with NiSource, Columbia of Massachusetts, Eversource, EGMA, the Massachusetts AGO and the DOER, the “Settling Parties”). The Settlement Agreement was conditioned on its approval by the Massachusetts DPU no later than September 30, 2020; however, this deadline was extended to October 7, 2020. The Settlement Agreement was approved by the Massachusetts DPU on October 7, 2020, and the closing of the Transaction occurred on October 9, 2020.

Set forth below are certain of the descriptions of the provisions of the Settlement Agreement related to the DPU Required Resolution. The Settlement Agreement includes other provisions, including generally provisions related to ratemaking and activities of Eversource and EGMA to occur after the closing of the Transaction and other conditions, as further described in the Settlement Agreement.

Termination of Massachusetts DPU Regulatory Matters. Under the Settlement Agreement, the Settling Parties agreed that the terms of the Settlement Agreement achieve the DPU Required Resolution under the Asset Purchase Agreement. Further, under the Settlement Agreement, Columbia of Massachusetts took responsibility for the Greater Lawrence Incident and agreed not to contest facts in the record sufficient to support the Massachusetts DPU’s investigations into pipeline safety and emergency response in the two public investigations that the Massachusetts DPU opened pursuant to the October 25, 2019 orders referenced above (DPU 19-140 and 19-141, respectively). If adjudicated, Columbia of Massachusetts could have been subject to the payment of penalties potentially up to the maximum allowed by law.

The Settling Parties also agreed that, upon the closing of the Transaction, (1) all pending actions, claims, investigations, lawsuits and proceedings against NiSource, Columbia of Massachusetts and their affiliates, and all of the respective directors, officers, employees, agents and representatives of NiSource and Columbia of Massachusetts and their affiliates (such entities and individuals, collectively referred to as the “Discharged Persons”), under the Massachusetts DPU’s jurisdiction, shall be

considered settled, resolved, and terminated; and (2) all future actions, claims, investigations, lawsuits and proceedings, whether known or unknown, against the Discharged Persons, in each case, relating to, arising out of, or in connection with the Greater Lawrence Incident (as defined in the Asset Purchase Agreement), under the jurisdiction of the Massachusetts DPU shall be considered settled, resolved, and terminated. This includes the Massachusetts DPU’s investigations into pipeline safety and emergency response in DPU 19-140 and 19-141, respectively, as well as any other regulatory matters that could have been raised by the Massachusetts DPU relating to, arising out of, or in connection with the Greater Lawrence Incident.

The Settling Parties also agreed that, upon the closing of the Transaction, all pending actions, claims, investigations, lawsuits, and proceedings against the Discharged Persons, which are the subject of the Consent Order, shall be settled, resolved, and terminated. The “Consent Order” is a consent order the Massachusetts DPU issued on August 14, 2020 in DPU 19-140, which included Compliance Actions (as defined in the Consent Order) that corresponded to the entirety of cases pending before the Massachusetts DPU as of July 2, 2020. The Settling Parties further agreed, upon the closing of the Transaction, that the Consent Order (and the Massachusetts DPU’s associated Compliance Actions) addresses all outstanding pipeline safety compliance investigations, inquiries, or ongoing matters, regardless of whether subject to notices of probable violations (NOPVs) or related to the Greater Lawrence Incident, existing as of the execution date of the Settlement Agreement.

Termination of Massachusetts AGO Matters. Under the Settlement Agreement, the Settling Parties agreed that, upon the closing of the Transaction, the Settlement Agreement shall constitute receipt from the Massachusetts AGO of an agreement, settlement, compromise, and consent: (1) to terminate with prejudice all pending actions, claims, lawsuits, investigations, or proceedings under the jurisdiction of the Massachusetts AGO against the Discharged Persons relating, arising out of, or in connection with, the Greater Lawrence Incident; and (2) not to commence on its own behalf any new action, claim, lawsuit, investigation or proceeding against any of the Discharged Persons relating, arising out of, or in connection with, the Greater Lawrence Incident.

Payment in Lieu of Penalties. Under the Settlement Agreement, the Settling Parties agreed that, at the closing of the Transaction, NiSource will make a payment in lieu of penalties in full settlement of all of the pending and potential claims, lawsuits, investigations or proceedings settled by and released by the Settlement Agreement in the amount of $56.0 million. This payment was withheld from the proceeds received from Eversource at the closing of the Transaction on October 9, 2020. See Note 6, "Assets and Liabilities Held for Sale," for additional information.

Energy Relief Fund. Under the Settlement Agreement, the Settling Parties agreed that the funds derived from the NiSource payment described above will be used to create an “Energy Relief Fund,” comprised of two components, designated as the “Merrimack Valley Renewal Fund” and the “Arrearage Forgiveness Fund,” in each case as further described in the Settlement Agreement. The Merrimack Valley Renewal Fund is jointly administered by the Massachusetts AGO and DOER. The Arrearage Forgiveness Fund is jointly administered by the Massachusetts AGO and Eversource.

U.S. Department of Justice Investigation. On February 26, 2020, the Company and Columbia of Massachusetts entered into agreements with the U.S. Attorney’s Office to resolve the U.S. Attorney’s Office’s investigation relating to the Greater Lawrence Incident. Columbia of Massachusetts agreed to plead guilty in the United States District Court for the District of Massachusetts (the “Court”) to violating the Natural Gas Pipeline Safety Act (the “Plea Agreement”), and the Company entered into a Deferred Prosecution Agreement (the “DPA”).

On March 9, 2020, Columbia of Massachusetts entered its guilty plea pursuant to the Plea Agreement, which the Court accepted. Subsequently, Columbia of Massachusetts and the U.S. Attorney’s Office modified the Plea Agreement. On June 23, 2020, the Court sentenced Columbia of Massachusetts in accordance with the terms of the modified Plea Agreement. Under the modified Plea Agreement, Columbia of Massachusetts is subject to the following terms, among others: (i) a criminal fine in the amount of $53,030,116, which has been paid; (ii) a three year probationary period that will terminate early upon a sale of Columbia of Massachusetts or a sale of its gas distribution business to a qualified third-party buyer consistent with certain requirements, but in no event before the end of the one-year mandatory period of probation; (iii) compliance with each of the NTSB recommendations stemming from the Greater Lawrence Incident; and (iv) employment of an in-house monitor until the end of the term of probation or until the sale of Columbia of Massachusetts or its gas distribution business, whichever is earlier. On October 13, 2020, the Court, upon agreement of the U.S. Attorney's Office and Columbia Gas of Massachusetts, modified the terms of probation by ending the term of the in-house monitor.

Under the DPA, the U.S. Attorney’s Office agreed to defer prosecution of the Company in connection with the Greater Lawrence Incident for a three-year period (which three-year period may be extended for twelve (12) months upon the U.S. Attorney’s Office’s determination of a breach of the DPA) subject to certain obligations of the Company, including, but not limited to, the following: (i) the Company will use reasonable best efforts to sell Columbia of Massachusetts or Columbia of Massachusetts’ gas distribution business to a qualified third-party buyer consistent with certain requirements, and, upon the completion of any such sale, the Company will cease and desist any and all gas pipeline and distribution activities in the District of Massachusetts; (ii) the Company will forfeit and pay, within 30 days of the later of the sale becoming final or the date on which post-closing adjustments to the purchase price are finally determined in accordance with the agreement to sell Columbia of Massachusetts or its gas distribution business, a fine equal to the total amount of the profit or gain, if any, from any sale of Columbia of Massachusetts or its gas distribution business, with the amount of profit or gain determined as provided in the DPA; and (iii) the Company agrees as to each of the Company’s subsidiaries involved in the distribution of gas through pipeline facilities in Massachusetts, Indiana, Ohio, Pennsylvania, Maryland, Kentucky and Virginia to implement and adhere to each of the recommendations from the NTSB stemming from the Greater Lawrence Incident. Pursuant to the DPA, if the Company complies with all of its obligations under the DPA, including, but not limited to those identified above, the U.S. Attorney’s Office will not file any criminal charges against the Company related to the Greater Lawrence Incident. If Columbia of Massachusetts withdraws its plea for any reason, if the Court rejects any aspect of the Plea Agreement, or if Columbia of Massachusetts should fail to perform an obligation under the Plea Agreement prior to the sale of Columbia of Massachusetts or its gas distribution business, the U.S. Attorney's Office may, at its sole option, render the DPA null and void. The sale of the Massachusetts Business was completed on October 9, 2020. The Company is not required to forfeit or pay any funds within 30 days of the sale of the Massachusetts Business because the Company did not realize a profit or gain from the sale as provided in the DPA.

U.S. Congressional Activity. On September 30, 2019, the U.S. Protecting Our Infrastructure of Pipelines and Enhancing Safety (PIPES) Act authorizing PHMSA expired. There is no effect on PHMSA's authority. Action on past re-authorization bills has extended past the expiration date and action on this re-authorization is expected to continue into 2021. Pipeline safety jurisdiction resides with the U.S. Senate Commerce Committee and is divided between two committees in the U.S. House of Representatives (Energy and Commerce, and Transportation and Infrastructure). The Senate passed its bill on August 7, 2020. The House of Representatives has yet to reconcile its legislation and act. Certain legislative proposals, if enacted into law, may increase costs for natural gas industry companies, including the Company.

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 have been 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 motion for preliminary approval and the settlement documents were filed on September 25, 2019. The preliminary approval court hearing was held on October 7, 2019 and the court issued an order granting preliminary approval of the settlement on October 11, 2019. The Court granted final approval of the settlement on March 12, 2020.

With respect to claims not included in the consolidated class action, many of the asserted wrongful death and bodily injury claims have settled, and we continue to discuss potential settlements with remaining claimants. 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.

Shareholder Derivative Lawsuit. On April 28, 2020, a shareholder derivative lawsuit was filed by the City of Detroit Police and Fire Retirement System in the United States District Court for the District of Delaware against certain of the Company’s current and former directors, alleging breaches of fiduciary duty with respect to the pipeline safety management systems relating to the distribution of natural gas prior to the Greater Lawrence Incident and also including claims related to the Company’s proxy statement disclosures regarding its safety systems. The remedies sought include damages for the alleged breaches of fiduciary duty, corporate governance reforms, and restitution of any unjust enrichment. The defendants have filed a motion to dismiss the lawsuit. The motion to dismiss is fully briefed. Because of the preliminary nature of this lawsuit, the Company is not able to estimate a loss or range of loss, if any, that may be incurred in connection with this matter at this time.

Financial Impact. Since the Greater Lawrence Incident, we have recorded expenses of approximately $1,036 million for third-party claims and fines, penalties and settlements associated with government investigations. We estimate that total costs related to third-party claims and fines, penalties and settlements associated with government investigations resulting from the incident will range from $1,036 million to $1,050 million, depending on the number, nature, final outcome and value of third-party claims. With regard to third-party claims, these costs include, but are not limited to, personal injury and property damage claims, damage to infrastructure, business interruption claims, and mutual aid payments to other utilities assisting with the restoration effort. These costs do not include costs of certain third-party claims and fines, penalties or settlements associated with government investigations that we are not able to estimate. These costs also do not include non-claims related and government investigation-related legal expenses resulting from the incident, the capital cost of the pipeline replacement and the payment in lieu of penalties, which are set forth in " - D. Other Matters - Greater Lawrence Incident Restoration," "- Greater Lawrence Incident Pipeline Replacement," and Note 6, "Assets and Liabilities Held for Sale," respectively.

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, management’s estimates and assumptions regarding the financial impact of the Greater Lawrence Incident may change.

The aggregate amount of third-party liability insurance coverage available for losses arising from the Greater Lawrence Incident is $800 million. We have collected the entire $800 million. Total expenses related to the incident have exceeded the total amount of insurance coverage available under our 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.

We are also party to certain other claims, regulatory and legal proceedings arising in the ordinary course of business in each state in which we have operations, none of which we believe to be individually material at this time.

Due to the inherent uncertainty of litigation, there can be no assurance that the outcome or resolution of any particular claim, proceeding or investigation related to the Greater Lawrence Incident or otherwise would not have a material adverse effect on our results of operations, financial position or liquidity. Certain matters in connection with the Greater Lawrence Incident have had or may have a material impact as described above. If one or more of such additional or other 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 September 30, 2020 and December 31, 2019, we had recorded a liability of $93.4 million and $104.4 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." 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 October 31, 2018. Refer to " - D. Other Matters - NIPSCO 2018 Integrated Resource Plan," below for additional information.

Air

Future legislative and regulatory programs could significantly limit allowed GHG emissions or impose a cost or tax on GHG emissions. Additionally, rules that require further GHG reductions or impose additional requirements for natural gas facilities could impose additional costs. NiSource will carefully monitor all GHG reduction proposals and regulations.

ACE Rule. On July 8, 2019, the EPA published the final ACE rule, which establishes emission 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 the end of 2023 and 2028, respectively, will be determined by future Indiana rulemaking. The ACE rule notes that states have “broad flexibility in setting standards of performance for designated facilities” and that a state may set a “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 have 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 result, NIPSCO will continue to monitor this matter and cannot estimate its impact at this time.

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 63 such sites where liability is probable as of September 30, 2020. After the sale of the Massachusetts Business, the retained number of identified sites is 54. 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 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, 2020. Our total estimated liability related to the facilities subject to remediation was $88.3 million and $102.2 million at September 30, 2020 and December 31, 2019, 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 $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 allows NIPSCO to continue its byproduct beneficial use program.

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

To comply with the rule, NIPSCO completed capital expenditures to modify its infrastructure and manage CCRs during 2019. 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 requirements that will be established by environmental authorities, compliance strategies that will be used, and the preliminary nature of available data used to estimate costs. As allowed by the rule, 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 initial CCR closure plans for R.M. Schahfer Generating Station and Michigan City Generating Station with the Indiana Department of 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. Based upon a study performed in 2016 of the final rule, capital compliance costs were expected to be approximately $170 million. On October 13, 2020, the EPA published a final rule that revises the ELG for certain water streams and considers coal unit retirement dates. NIPSCO does not anticipate material ELG compliance costs based on the preferred option announced as part of NIPSCO's 2018 Integrated Resource Plan (discussed below).

D. Other Matters.

NIPSCO 2018 Integrated Resource Plan. 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 Integrated Resource Plan submission that NIPSCO’s current fleet of coal generation facilities will be retired earlier than previous Integrated Resource Plans had indicated.

In the second quarter of 2020, the MISO approved NIPSCO's plan to retire the R.M. Schahfer Generating Station in 2023. In accordance with ASC 980-360, the net book value of certain plant and equipment for the R.M. Schahfer Generating Station was reclassified from "Net utility plant" to "Other property, at cost, less accumulated depreciation" on the Condensed Consolidated Balance Sheets (unaudited). The December 2019 NIPSCO electric rate case order included approval to create a regulatory asset upon the retirement of the R.M. Schahfer Generating Station. The order allows for the recovery of and on the net book value of the station by the end of 2032. Refer to Note 7, "Property, Plant and Equipment" for further information.

In connection with the MISO's approval of NIPSCO's planned retirement of the R.M. Schahfer Generating Station, we recorded $4.6 million of plant retirement-related charges in the second quarter of 2020. These charges were comprised of write downs of certain capital projects that have been cancelled and materials and supplies inventory balances deemed obsolete due to the planned retirement. These charges are presented within "Operation and maintenance" on the Condensed Statements of Consolidated Income (Loss). As more information becomes available, the retirement date of the R.M. Schahfer Generating Station will be finalized, and additional plant retirement-related charges may be incurred.

In connection with the planned retirement of the Schahfer Generating Station and the Michigan City Generating Station, the current capacity replacement plan includes lower-cost, reliable, cleaner energy resources to be obtained through a combination of NIPSCO ownership and PPAs. To this effect, NIPSCO has entered into a number of agreements with counterparties, as described below.

In January 2019, NIPSCO executed a 20 year PPA, referred to as the Jordan Creek PPA, to purchase 100% of the output from renewable generation facilities at a fixed price per MWh. The facility supplying the energy will have a nameplate wind capacity of approximately 400 MW. NIPSCO submitted the Jordan Creek PPA to the IURC for approval in February 2019 and the IURC approved the Jordan Creek PPA on June 5, 2019. Payments under the Jordan Creek PPA will not begin until the associated generation facility is constructed by the owner / seller, which is currently scheduled to be complete by the end of 2020. While NIPSCO is monitoring any possible impact the COVID-19 pandemic may have on the expected completion date of this project, we do not expect delays.

Also in January 2019, NIPSCO executed a BTA, referred to as the Rosewater BTA, with a developer to construct a renewable generation facility with a nameplate wind capacity of approximately 100 MW. Ownership of the facility will be transferred to a

Table of Contents

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

joint venture whose members include NIPSCO, the developer and an unrelated tax equity partner. NIPSCO and the tax equity partner are obligated to make cash contributions to the partnership at the date construction is substantially complete. The aforementioned joint venture is expected to be fully owned by NIPSCO after the wind PTCs are monetized from the project. NIPSCO's purchase requirement under the Rosewater BTA is dependent on satisfactory approval of the Rosewater BTA by the IURC, successful execution of an agreement with a tax equity partner and timely completion of construction. NIPSCO submitted the Rosewater BTA to the IURC for approval in February 2019, and the IURC approved the Rosewater BTA on August 7, 2019. The required FERC approvals for the project were received in December 2019. NIPSCO executed an equity capital contribution agreement with a tax equity partner in July 2020. Construction of the facility is scheduled to be completed by the end of 2020; however, this project could experience a construction delay due to the COVID-19 pandemic. While NIPSCO is continuing to monitor the impact the COVID-19 pandemic may have on the expected completion date of this project, we do not expect delays.

On October 1, 2019, NIPSCO announced the opening of its next round of RFP to consider potential resources to meet the future electric needs of its customers. The RFP closed on November 20, 2019, and NIPSCO continues to evaluate the results. NIPSCO is considering all sources in the RFP process and is expecting to obtain adequate resources to facilitate the retirement of the R.M. Schahfer Generation Station by the end of 2023. The planned replacement by the end of 2023 of approximately 1,400 MW from this coal-fired generation station could provide incremental capital investment opportunities for 2022 and 2023. Currently, half of the capacity in the replacement plan is targeted to be owned by joint ventures that will include NIPSCO and unrelated financial investors as the members. The remaining new capacity is expected to be primarily in the form of PPAs. NIPSCO has initiated the appropriate regulatory compliance filings related to the new capacity, starting with two solar PPAs filed with the IURC in July 2020. We expect to continue finalizing agreements with counterparties and initiating regulatory compliance filings into 2021.

In October 2019, NIPSCO executed a BTA, referred to as the Indiana Crossroads BTA, with a developer to construct an additional renewable generation facility with a nameplate wind capacity of approximately 300 MW. Ownership of the facility will be transferred to a joint venture whose members include NIPSCO, the developer and an unrelated tax equity partner. NIPSCO and the tax equity partner are obligated to make cash contributions to the partnership at the date construction is substantially complete. The aforementioned joint venture is expected to be fully owned by NIPSCO after the wind PTCs are monetized from the project. NIPSCO's purchase requirement under the Indiana Crossroads BTA is dependent on satisfactory approval of the Indiana Crossroads BTA by the IURC, successful execution of an agreement with a tax equity partner, and timely completion of construction. NIPSCO submitted the Indiana Crossroads BTA to the IURC for approval on October 22, 2019, and the IURC approved the Indiana Crossroads BTA on February 19, 2020. Required FERC filings are expected to be filed in the fourth quarter of 2020. Construction of the facility is expected to be completed by the end of 2021.

In June 2020, NIPSCO executed three additional 20 year PPAs to purchase 100% of the output from renewable generation facilities at a fixed price per MWh. The facilities supplying the energy will have a combined nameplate solar capacity of approximately 500 MW and 30 MW storage capacity. NIPSCO's purchase requirement under the PPAs is dependent on satisfactory approval of the PPAs by the IURC. NIPSCO submitted two of the PPAs to the IURC for approval in July 2020. An IURC order is anticipated by the end of the fourth quarter of 2020. NIPSCO plans to submit the third PPA to the IURC for approval in the fourth quarter of 2020. If approved by the IURC, payments under the PPAs will not begin until the associated generation facilities are constructed by the owner / seller, which is expected to be complete by the second quarter of 2023.

In October 2020, NIPSCO executed three solar BTAs with a developer to construct additional renewable generation facilities with a nameplate solar capacity of approximately 900 MW and 135 MW of storage capacity. Ownership of the facilities will be transferred to joint ventures whose members include NIPSCO and an unrelated tax equity partner. NIPSCO and the tax equity partner are obligated to make cash contributions to the partnerships at the date construction is substantially complete. The aforementioned joint ventures are expected to be fully owned by NIPSCO after the solar ITCs are monetized from the project. NIPSCO's purchase requirement under the BTAs is dependent on satisfactory approval of the BTAs by the IURC, successful execution of an agreement with a tax equity partner, and timely completion of construction. NIPSCO plans to submit the BTAs to the IURC for approval in the fourth quarter of 2020. Construction of the facility with a nameplate capacity of 265 MW is expected to be completed by the end of 2022. Construction of the facilities with a nameplate capacity of 635 MW and 135 of storage capacity are expected to be completed by the end of 2023.

On May 1, 2020, President Donald Trump issued an executive order (the “EO”) prohibiting any transaction initiated after that day that (i) involves bulk-power system equipment designed, developed, manufactured or supplied by persons owned by, controlled by or subject to the jurisdiction or direction of a foreign adversary and (ii) poses an unacceptable risk to national

security. Implementing regulations from the U.S. Secretary of Energy are still pending. The EO also requires the U.S. Secretary of Energy to review the risk of existing bulk-power system equipment sourced from foreign adversaries and to establish a task force to review and recommend federal procurement policies and procedures consistent with the considerations identified in the EO. On July 8, 2020, the U.S. Department of Energy issued a Request for Information (“RFI”), seeking input from industry stakeholders to “understand the energy industry’s current practices to identify and mitigate vulnerabilities in the supply chain” for components of bulk-power system equipment. The RFI identifies the following governments as “foreign adversaries”: China, Cuba, Iran, North Korea, Russia and Venezuela. The RFI notes that the U.S. Secretary of Energy retains authority to amend this list at any time and such countries have been identified only for the purposes of the EO. In the future, certain bulk-power system equipment owned or operated by NiSource could possibly be considered to be sourced from a foreign adversary within the meaning of the EO.

Greater Lawrence Incident Restoration. In addition to the amounts estimated for third-party claims and fines, penalties and settlements associated with government investigations described above, since the Greater Lawrence Incident, we have recorded expenses of approximately $441 million for other incident-related costs. We estimate that total other incident-related costs will range from $445 million and $455 million, depending on the incurrence of costs associated with resolving outstanding third-party claims discussed above in " - B. Legal Proceedings." Such costs include certain consulting costs, legal costs, vendor 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 capital cost of the pipeline replacement, which is set forth below.

As discussed in "- B. Legal Proceedings," the aggregate amount of third-party liability insurance coverage available for losses arising from the Greater Lawrence Incident is $800 million. We have collected the entire $800 million. Expenses related to the incident have exceeded the total amount of insurance coverage available under our policies.

The following table summarizes expenses incurred and insurance recoveries recorded since the Greater Lawrence Incident. This activity is presented within "Operation and maintenance" and "Other, net' in our Condensed Statements of Consolidated Income (Loss) (unaudited).

Greater Lawrence Pipeline Replacement. In connection with the Greater Lawrence Incident, Columbia of Massachusetts, in cooperation with the Massachusetts Governor’s office, replaced the entire affected 45-mile cast iron and bare steel pipeline system that delivers gas to approximately 7,500 gas meters, the majority 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.

We have invested approximately $258 million of capital spend for the pipeline replacement; this work was completed in 2019. We maintain property insurance for gas pipelines and other applicable property. Columbia of Massachusetts has filed a proof of loss with its property insurer for the pipeline replacement. In January 2020, we filed a lawsuit against the property insurer, seeking payment of our property claim. We are currently unable to predict the timing or amount of any insurance recovery under the property policy. This pipeline replacement cost is part of the Massachusetts Business that was classified as held for sale at September 30, 2020. The assets and liabilities of the Massachusetts Business have been recorded at fair value, less costs to sell, which has resulted in a loss being recorded as of September 30, 2020. The sale of the Massachusetts Business was completed on October 9, 2020. See Note 6, "Assets and Liabilities Held for Sale," for additional information.

State Income Taxes Related to Greater Lawrence Incident Expenses. As of December 31, 2018, expenses related to the Greater Lawrence Incident were $1,023 million. In the fourth quarter of 2019, we filed an application for Alternative Apportionment with the MA DOR to request an allocable approach to these expenses for purposes of Massachusetts state

Table of Contents

ITEM 1. FINANCIAL STATEMENTS (continued)

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

income taxes, which, if approved, would result in a state deferred tax asset of approximately $50 million, net. The MA DOR issued a denial during the first quarter of 2020. We filed an application for abatement in the second quarter of 2020 and believe it is reasonably possible that the application will be accepted or an alternative method will be proposed by the MA DOR within the next three to six months.

Voluntary Separation Program. On August 5, 2020, we commenced a voluntary separation program for certain employees. Expense for the voluntary separation program will be recognized in the period when the employee accepts the offer, absent a retention period. For employees that have a retention period, expense will be recognized over the remaining service period. Employee acceptance under the voluntary separation program is determined by management based on facts and circumstances of the benefits being offered. The total severance expense for employees who were accepted under the voluntary separation program offered in August 2020 is approximately $38 million, which will be recognized over the remaining service period of the applicable employees. For the three and nine months ended September 30, 2020, we recognized $23.4 million in severance expense related to the program, all of which was outstanding at September 30, 2020. This activity is presented within "Operation and maintenance" in our Condensed Statements of Consolidated Income (Loss) (unaudited) and within "Accrued compensation and employee benefits" in our Condensed Consolidated Balance Sheets (unaudited).

Transition Services Agreement. In connection with the sale of the Massachusetts Business, NiSource and Eversource entered into a Transition Services Agreement (TSA). Under the TSA, NiSource will provide Eversource certain finance and accounting, gas operations, customer, human resources, information technology and other specific services, The duration of the TSA varies by service, generally lasting 12 to 24 months from the date of the sale. As the TSA commenced on October 9, 2020, we did not record any revenue for the TSA for the three and nine months ended September 30, 2020.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

NiSource Inc.

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, 2019.

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 six states, following the sale of our Massachusetts Business, which closed on October 9, 2020. See "Columbia of Massachusetts Asset Sale" below for additional information. 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, 2019 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.

Columbia of Massachusetts Asset Sale: On February 26, 2020, NiSource and Columbia of Massachusetts entered into an Asset Purchase Agreement with Eversource (the "Asset Purchase Agreement"). Upon the terms and subject to the conditions set forth in the Asset Purchase Agreement, we sold the Massachusetts Business to Eversource for net proceeds of $1,112.6 million in cash, subject to adjustment for the final working capital amount. The sale was approved by the Massachusetts DPU on October 7, 2020, and closed on October 9, 2020. As a result of the sale, we have transitioned to executing the TSA with Eversource. For additional information, see Note 6, "Assets and Liabilities Held for Sale," and Note 18-D, "Other Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited).

Your Energy, Your Future: Our plan to replace 80% of our coal generation capacity by the end of 2023 and all of our coal generation by the end of 2028 with primarily renewable resources is well underway. In October 2020, we executed three BTAs for 900 MW solar nameplate capacity and 135 MW of storage capacity. The three projects were selected following a comprehensive review of bids submitted through the RFP process that NIPSCO underwent in late 2019. The projects complement previously executed BTAs and PPAs with a combined nameplate capacity of 400 MW and 1,300 MW, respectively. For additional information, see Note 18-D, "Other Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited).

NiSource Next: We have launched a comprehensive, multi-year program designed to deliver long-term safety, sustainable capability enhancements and cost optimization improvements. This program will advance the high priority we place on safety and risk mitigation, further enable our safety management system ("SMS"), and enhance the customer experience. NiSource Next is designed to leverage our current scale, utilize technology, define clear roles and accountability with our leaders and employees, and standardize our processes to focus on operational rigor, quality management and continuous improvement. An initial step in this program is the voluntary separation program that was announced in August 2020. Total severance expense for employees who were accepted under the voluntary separation program offered in August 2020 is approximately $38.0 million. The majority of these separation costs will be expensed in 2020. For additional information, see Note 18-D, "Other Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited). One of the expected benefits of the NiSource Next initiative, along with the sale of the Massachusetts Business, is a projected reduction in ongoing operation and maintenance costs by approximately 8% in 2021 compared to 2020.

COVID-19: The safety of our employees and customers, while providing essential services during the COVID-19 pandemic, is paramount. Since March 2020, we have taken a proactive, coordinated approach intended to prevent, mitigate and respond to

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

NiSource Inc.

COVID-19 by utilizing our Incident Command System (ICS). The ICS includes members of our executive council, a medical review professional, and members of functional teams from across our company. The ICS monitors state-by-state conditions and determines steps to conduct our operations safely for employees and customers.

We have implemented procedures designed to protect our employees who work in the field and who continue to work in operational and corporate facilities, including social distancing, wearing face coverings, temperature checks and more frequent cleaning of equipment and facilities. We have also implemented work-from-home policies. We have minimized non-essential work that requires an employee to enter a customer premise and limited company vehicle occupancy to one person, where possible. We continue to employ physical and cyber-security measures to ensure that our operational and support systems remain functional. Our actions to date have mitigated the impact of COVID-19 on our employees. We have had a limited amount of known COVID-19 cases within our company. We will continue to follow CDC guidance and implement safety measures intended to ensure employee and customer safety during this pandemic.

Since the beginning of the COVID-19 pandemic, we have been helping our customers navigate this challenging time. We suspended disconnections soon after this outbreak began. While the suspension of disconnections has been lifted in some states, suspensions are likely to continue in other states through the end of the year. In all states, we plan to continue our payment assistance programs to help customers deal with the impact of COVID-19. Additionally, we continue to have dialogue with the state regulatory commissions for each of our operating companies regarding COVID-19. Regulatory deferrals have been allowed by the state regulatory commissions in all states in which we operate. For information on the state specific suspension of disconnections and COVID-19 regulatory filings, see Note 9, "Regulatory Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited). The CARES Act was enacted on March 27, 2020 and provides monetary-relief and financial aid to individuals, business, nonprofits, states and municipalities. We are continuing to promote multiple resources available to customers including benefits from the CARES Act, such as additional funding for both the Low-Income Home Energy Assistance Program and the Community Services Block Grant to help support income-qualified customers. We are sharing energy efficiency tips to help customers save energy at home and promoting our budget plan program, which allows customers to pay about the same amount each month.

While we have experienced lower revenue, higher expenses for personal protective equipment and supplies, and higher bad debt expense, COVID-19 has not materially impacted our results of operation as of September 30, 2020. Refer to "Results and Discussion of Segment Operation" in this Management's Discussion for additional segment specific information. We did experience lower cash flows from operations for the nine months ended September 30, 2020 in comparison to the same period in 2019 due, in part, to slower collections of customer accounts receivable; however, we believe we have sufficient liquidity as a result of the issuance of $1.0 billion notes in April 2020, the remaining cash proceeds received from the sale of the Massachusetts Business in October 2020, the available capacity under our short-term revolving credit facility and accounts receivable securitization facilities, and our anticipated ability to access capital markets. Additionally, we have reduced our expected 2020 capital investments by $145 million. We do not anticipate any other material changes to our capital construction programs or our renewable generation projects. While we have not experienced any significant issues in our supply chain, we are actively managing the materials, supplies, and contract services for our generation, transmission, distribution, and customer services functions.

Our future operating results and liquidity may be impacted by COVID-19, but the extent of the impact is uncertain as we approach the winter months and experience fluctuations in the number of confirmed COVID-19 cases. Such ongoing impact of COVID-19 includes, but is not limited to:

•Lower revenue and cash flow during the fourth quarter of 2020, in comparison to the fourth quarter of 2019, resulting from the decrease in commercial and industrial gas and electric demand as businesses comply with re-opening plans in each state and as businesses experience negative economic impact from COVID-19, potentially offset by higher residential demand.

•Lower revenue and cash flow during the fourth quarter of 2020, in comparison to the fourth quarter of 2019, due to the continuing suspension of late payment and reconnection fees in some jurisdictions.

•A decline in revenue in 2021 due to an increase in customer attrition rates, as well as lower revenue growth if customer additions slow due to a prolonged economic downturn.

•A continued increase in bad debt and decrease in cash flows in the fourth quarter of 2020 and into 2021 resulting from the suspension of shut-offs and the inability of our customers to pay for their gas and electric service due to job loss or other factors, partially offset by regulatory deferral.

•A continued delay in cash flows in 2020 as customers utilized the more flexible payment plans.

NiSource Inc.

•An increase in internal labor costs from higher overtime in the fourth quarter of 2020.

•The impact of the employer payroll tax credit and payroll tax payment deferral under the CARES Act. We believe the deferral of payroll tax payments could provide a cash flow benefit in 2020 by delaying about $30.0 million of payroll tax payments. The IRS continues to provide additional guidance related to the employer tax credit. We do not expect the impact of employer payroll tax credits to be material.

Greater Lawrence Incident: For the three and nine months ended September 30, 2020, we have incurred $2.0 million and $16.0 million of third-party claims and other incident-related costs associated with the Greater Lawrence Incident, respectively. For additional information, see Note 18-B and D, "Legal Proceedings" and "Other Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited).

We have invested approximately $258 million of capital spend for the pipeline replacement; this work was completed in 2019. We maintain property insurance for gas pipelines and other applicable property. Columbia of Massachusetts has filed a proof of loss with its property insurer for the pipeline replacement. In January 2020, we filed a lawsuit against the property insurer, seeking payment of our property claim. We are currently unable to predict the timing or amount of any insurance recovery under the property policy. This pipeline replacement cost is part of the Massachusetts Business that is classified as held for sale at September 30, 2020. The assets and liabilities of the Massachusetts Business have been recorded at fair value, less costs to sell, which has resulted in a loss being recorded as of September 30, 2020. The sale of the Massachusetts Business was completed on October 9, 2020. See Note 6, "Assets and Liabilities Held for Sale," in the Notes to Condensed Consolidated Financial Statements (unaudited) for additional information.

Refer to Note 18-B and D, "Legal Proceedings" and "Other Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited), "Summary of Consolidated Financial Results," and "Results and Discussion of Segment Operation - Gas Distribution Operations," in this Management's Discussion for additional information related to the Greater Lawrence Incident.

Our operations are affected by the cost of sales. Cost of sales (excluding depreciation and amortization) 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 (excluding depreciation and amortization) 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 (excluding depreciation and amortization) are tracked costs that are passed through directly to the customer, resulting in an equal and offsetting amount reflected in operating revenues.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

NiSource Inc.

On a consolidated basis, we reported a net loss available to common shareholders of $186.7 million, or $0.49 per basic share for the three months ended September 30, 2020, compared to a net loss available to common shareholders of $7.2 million, or $0.02 per basic share for the same period in 2019. The increase in loss was primarily due to a loss on early extinguishment of debt in 2020. This was partially offset by higher income tax benefit in the third quarter of 2020 (see "Income Taxes" below).

For the nine months ended September 30, 2020, we reported a net loss available to common shareholders of $143.4 million, or $0.37 per basic share compared to net income available to common shareholders of $481.0 million, or $1.29 per basic share for the same period in 2019. The drivers for this decrease were consistent with that of the quarter-to-date period, with the addition of higher operating expenses due to insurance recoveries recorded in 2019, net of third-party claims and other costs, related to the Greater Lawrence Incident and a loss recorded for the classification as held for sale of the Massachusetts Business during 2020 (see Note 6, "Assets and Liabilities Held for Sale," in the Notes to the Condensed Consolidated Financial Statements (unaudited) for additional information).

Operating Income

For the three months ended September 30, 2020, we reported operating income of $92.8 million compared to operating income of $91.0 million for the same period in 2019.

For the nine months ended September 30, 2020, we reported operating income of $332.7 million compared to operating income of $928.7 million for the same period in 2019. The decrease in operating income was primarily due to the loss recorded for the classification as held for sale of the Massachusetts Business (see Note 6, "Assets and Liabilities Held for Sale," in the Notes to the Condensed Consolidated Financial Statements (unaudited) for additional information) and higher operating expenses due to insurance recoveries recorded in 2019, net of third-party claims and other costs, related to the Greater Lawrence Incident. In addition, COVID-19 impacted our results of operation as we have experienced a decrease in the commercial and industrial demand for gas and electric and incremental COVID-19 related expenses. We also experienced an increase in severance and outside services expenses related to the NiSource Next initiative. These expense increases were partially offset by new rates from regulatory proceedings, as well as an increase in the residential demand for electric primarily due to COVID-19.

Other Deductions, net

Other deductions, net reduced income by $330.6 million in the third quarter of 2020 compared to a reduction in income of $94.6 million in the prior year. This increase was primarily driven by a loss on early extinguishment of debt in 2020, partially offset by income from the sale of emission reduction credits in 2020. See Note 16, "Long-Term Debt," in the Notes to the Condensed Consolidated Financial Statements (unaudited) for additional information on the loss on early extinguishment of debt.

Other deductions, net reduced income by $508.6 million during the nine months ended September 30, 2020 compared to a reduction in income of $285.3 million in the prior year. The drivers for this change were consistent with that of the quarter-to-date period, partially offset by lower non-service pension costs driven by a decrease in the pension benefit obligations.

Income Taxes

For the three months ended September 30, 2020, the increase in income tax benefit from 2019 to 2020 is primarily attributable to the increased loss before income taxes in the third quarter of 2020, as well as a lower effective tax rate in 2020 due to the relative impact of permanent differences on lower pre-tax loss in 2019 compared to 2020.

For the nine months ended September 30, 2020, the change from an income tax expense to an income tax benefit from 2019 to 2020 is primarily attributable to the change from income before income taxes in 2019 to loss before income taxes in 2020, offset by a higher effective tax rate in 2020 due to increased amortization of excess deferred federal income tax liabilities, as specified in the TCJA in 2020 compared to 2019.

Refer to Note 14, "Income Taxes," in the Notes to Condensed Consolidated Financial Statements (unaudited) for information on income taxes and the change in the effective tax rate.

Capital Investment

For the nine months ended September 30, 2020, we invested $1,292.2 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, system modernization projects and maintaining our existing electric generation fleet.

NiSource Inc.

We continue to execute on an estimated $40 billion in total projected long-term regulated utility infrastructure investments and expect to invest a total of approximately $1.7 to $1.8 billion in capital during 2020 as we continue to focus on growth, safety and modernization projects across our operating area.

Liquidity

A primary focus of ours is to ensure the availability of adequate financing to fund our ongoing safety and infrastructure investment programs, which typically involves the issuance of debt and/or equity. During 2020, we took certain actions to enhance our liquidity. In April 2020, we terminated and repaid in full our existing $850.0 million term loan agreement and entered into a new $850.0 million term loan agreement. On October 14, 2020, this term loan was repaid in full with proceeds from the sale of the Massachusetts Business. Also, in April 2020, we completed the issuance and sale of $1.0 billion of senior unsecured notes resulting in approximately $987.8 million of net proceeds.

Through income generated from operating activities, amounts available under our short-term revolving credit facility, commercial paper program, accounts receivable securitization facilities, long-term debt agreements, remaining cash proceeds received from the sale of the Massachusetts Business in October 2020, and our ability to access the capital markets, we expect to have adequate capital available to fund our operating activities, capital expenditures, and the effects of COVID-19 through 2020 and beyond. As of September 30, 2020 and December 31, 2019, we had $1,591.4 million and $1,409.1 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.”

Cost of sales (excluding depreciation and amortization) for the Gas Distribution Operations segment is principally comprised of the cost of natural gas used while providing transportation and distribution services to customers. The cost of sales (excluding depreciation and amortization) are tracked costs that are passed through directly to the customer resulting in an equal and offsetting amount reflected in operating revenue. In addition, comparability of operation and maintenance expenses, depreciation and amortization, and other taxes may be impacted by regulatory, depreciation and tax trackers that allow for the recovery in rates of certain costs. Therefore, increases in these tracked operating expenses are offset by increases in operating revenues and have essentially no impact on net income.

•Lower cost of sales (excluding depreciation and amortization) billed to customers, which is offset in operating expense, of $10.0 million.

•The effects of decreased commercial and industrial usage primarily related to COVID-19 of $2.6 million.

•The effects of decreased late payment and reconnection fees primarily related to COVID-19 of $1.2 million.

Operating expenses were $0.2 million lower for the three months ended September 30, 2020 compared to the same period in 2019. This change was primarily driven by:

•Lower third-party claims and other costs related to the Greater Lawrence Incident of $18.9 million.

•Lower employee and administrative expenses of $16.1 million.

•Lower depreciation and amortization of $14.1 million due to a $15.0 million decrease in depreciation and amortization as a result of classifying the Massachusetts Business as held for sale, offset by a $0.9 million increase in depreciation and amortization primarily due to higher capital expenditures placed in service.

•Lower cost of sales (excluding depreciation and amortization) billed to customers, which is offset in operating revenue, of $10.0 million.

•Lower outside service costs of $5.1 million primarily related to decreased consulting costs in 2020.

Partially offset by:

•Loss on classification as held for sale related to the Massachusetts Business of $35.6 million.

•Severance and outside services expenses related to the NiSource Next initiative of $18.8 million.

•Third-party consulting costs incurred for the separation and transition of the Massachusetts Business to Eversource of $11.0 million.

•Third-party consulting costs incurred for the separation and transition of the Massachusetts Business to Eversource of $16.2 million.

•Increased property taxes of $7.8 million due to higher capital expenditures placed in service.

•Increased bad debt expense primarily related to COVID-19 of $6.7 million.

•Increased expenses primarily due to the impact of COVID-19 related materials & supplies, outside services, and sequestration expenses of $5.6 million.

Partially offset by:

•Lower cost of sales (excluding depreciation and amortization) billed to customers, which is offset in operating revenue, of $200.2 million.

•Lower depreciation and amortization of $27.4 million due to a $35.0 million decrease in depreciation and amortization as a result of classifying the Massachusetts Business as held for sale, offset by a $7.6 million increase in depreciation and amortization primarily due to higher capital expenditures placed in service.

•Lower employee and administrative expenses of $26.0 million.

•Lower regulatory, tax and depreciation trackers, which are offset in operating revenue, of $10.9 million.

•Lower outside service costs of $10.9 million primarily related to decreased consulting costs in 2020.

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.

Weather in the Gas Distribution Operations service territories for the third quarter of 2020 was about 28% colder than normal and about 600% colder than 2019, leading to increased operating revenues of $2.3 million for the quarter ended September 30, 2020 compared to the same period in 2019.

Weather in the Gas Distribution Operations service territories for the nine months ended September 30, 2020 was about 8% warmer than normal and about 4% warmer than 2019, leading to decreased operating revenues of $29.4 million for the nine months ended September 30, 2020 compared to the same period in 2019.

Throughput

Total volumes sold and transported for the three months ended September 30, 2020 were 168.9 MMDth, compared to 172.5 MMDth for the same period in 2019. This decrease is due to decreased usage by industrial customers primarily due to COVID-19.

Total volumes sold and transported for the nine months ended September 30, 2020 were 715.8 MMDth, compared to 749.7 MMDth for the same period in 2019. This decrease is primarily attributable to warmer weather in 2020 compared to 2019 and decreased usage by commercial and industrial customers primarily due to COVID-19.

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 operating income recorded in the period. The gas costs included in revenues are matched with the gas cost expense recorded in the period and the

Cost of sales (excluding depreciation and amortization) for the Electric Operations segment is principally comprised of the cost of coal, related handling costs, natural gas purchased for 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 (excluding depreciation and amortization) are tracked costs that are passed through directly to the customer resulting in an equal and offsetting amount reflected in operating revenue. In addition, comparability of operation and maintenance expenses and depreciation and amortization may be impacted by regulatory and depreciation trackers that allow for the recovery in rates of certain costs. Therefore, increases in these tracked operating expenses are offset by increases in operating revenues and have essentially no impact on net income.

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.

Weather in the Electric Operations’ territories for the third quarter of 2020 was about 8% warmer than normal and about 17% cooler than in 2019, which had an immaterial impact on operating revenues for the quarter ended September 30, 2020 compared to the same period in 2019.

Weather in the Electric Operations’ territories for the nine months ended September 30, 2020 was about 12% warmer than normal and about 5% cooler than in 2019, which had an immaterial impact on operating revenues for the nine months ended September 30, 2020 compared to the same period in 2019.

Sales

Electric Operations sales for the third quarter of 2020 were 4,080.1 GWh, a decrease of 275.8 GWh compared to the same period in 2019. This decrease was primarily attributable to decreased usage by industrial and commercial customers due to COVID-19 and higher self-generation by industrial customers, partially offset by increased usage by residential customers primarily due to COVID-19.

Electric Operations sales for the nine months ended September 30, 2020 were 11,044.7 GWh, a decrease of 1,066.7 GWh compared to the same period in 2019. This decrease was primarily attributable to decreased usage by industrial and commercial customers due to COVID-19 and higher self-generation by industrial customers, partially offset by increased usage by residential customers primarily due to COVID-19.

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 operating income 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 Operations

have led NIPSCO to conclude in its October 2018 Integrated Resource Plan submission that NIPSCO’s current fleet of coal generation facilities will be retired earlier than previous Integrated Resource Plan’s had indicated.

The Integrated 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 preferred option within the Integrated Resource Plan retires the R.M. Schahfer Generating Station by the end of 2023 and the Michigan City Generating Station by the end of 2028. These stations represent 2,080 MW of generating capacity, equal to 72% of NIPSCO’s remaining capacity and 100% of NIPSCO's remaining coal-fired generating capacity. In the second quarter of 2020, the MISO approved NIPSCO's plan to retire the R.M. Schahfer Generating Station in 2023. The planned replacement by the end of 2023 of approximately 1,400 MW of retiring coal-fired generation station could provide incremental capital investment opportunities of approximately $1.8 to $2.0 billion, primarily in 2022 and 2023. Refer to Note 7, "Property, Plant and Equipment" and Note 18-D, "Other Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited) for further information.

The current replacement plan includes lower-cost, reliable, cleaner energy resources to be obtained through a combination of NIPSCO ownership and PPAs. We expect to secure additional agreements with counterparties and initiate regulatory compliance filings into 2021. Refer to Note 18-D, "Other Matters," in the Notes to Condensed Consolidated Financial Statements (unaudited) for additional information on the NIPSCO Integrated Resource Plan.

Liquidity and Capital Resources

Greater Lawrence Incident: As discussed in the "Executive Summary" and Note 18, “Other Commitments and Contingencies,” in the Notes to the Condensed Consolidated Financial Statements (unaudited), due to the inherent uncertainty of litigation, there can be no assurance that the outcome or resolution of any particular claim related to the Greater Lawrence Incident will not continue to have an adverse impact on our cash flows. Through income generated from operating activities, amounts available under the short-term revolving credit facility, and our ability to access capital markets, we believe we have adequate capital available to fund the estimated future incremental costs associated with the Greater Lawrence Incident. Previous costs in excess of insurance recoveries were primarily funded through short-term borrowings. The sale of the Massachusetts Business was completed on October 9, 2020. On October 14, 2020, we used a portion of the proceeds from the Massachusetts Business sale to pay down these short-term borrowings. For more information, see Note 6, "Assets and Liabilities Held for Sale," in the Notes to the Condensed Consolidated Financial Statements (unaudited).

Operating Activities

Net cash from operating activities for the nine months ended September 30, 2020 was $858.6 million, a decrease of $373.2 million compared to the nine months ended September 30, 2019. This decrease was primarily driven by year over year increase in net payments related to the Greater Lawrence Incident. During 2020, we paid approximately $222 million compared to insurance recoveries of $242 million, net of payments, during 2019. Additionally, we had lower accounts receivable collections in 2020 compared to 2019 due to the impact of COVID-19. Offsetting these cash outflows are lower spend on gas inventory due to warmer weather and lower usage in 2020, and an increase in cash from the recent NIPSCO Electric base rate proceeding.

Investing Activities

Net cash used for investing activities for the nine months ended September 30, 2020 was $1,399.9 million, an increase of $6.1 million compared to the nine months ended September 30, 2019. This increase was driven by increased net available-for-sale debt security purchases in 2020.

Our capital expenditures for the nine months ended September 30, 2020 were $1,292.2 million compared to $1,310.0 million for the comparable period in 2019. The decrease was driven primarily by 2019 spend related to the Greater Lawrence Pipeline Replacement and a year-over-year reduction in Electric TDSIC investments, partially offset by an increase in customer growth, NIPSCO Gas tracked investments and IT modernization projects. We project total 2020 capital expenditures to be approximately $1.7 to $1.8 billion.

Our cost of removal expenditures for the nine months ended September 30, 2020 were $102.1 million compared to $84.5 million for the comparable period in 2019. The increase was driven by additional cost of removal projects completed by NIPSCO and Columbia of Ohio.

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 September 30, 2020, the collateral requirement that would be required in the event of a downgrade below the ratings trigger levels would amount to approximately $74.6 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.

Equity. Our authorized capital stock consists of 620,000,000 shares, $0.01 par value, of which 600,000,000 are common stock and 20,000,000 are preferred stock. As of September 30, 2020, 383,114,130 shares of common stock and 440,000 shares of preferred stock were outstanding.

Contractual Obligations. Aside from the previously referenced issuances and repayments of long-term debt and payments associated with the Greater Lawrence Incident, there were no material changes during the nine months ended September 30, 2020 to our contractual obligations as of December 31, 2019.

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. Refer to Note 18, “Other

Off Balance Sheet Arrangements

We, along with certain of our subsidiaries, enter into various agreements providing financial or performance assurance to third parties on behalf of certain subsidiaries. Such agreements include guarantees and stand-by letters of credit.

Refer to Note 18, “Other Commitments and Contingencies,” in the Notes to Condensed Consolidated Financial Statements (unaudited) for additional information about such arrangements.

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. We manage risk through 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 10, "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 September 30, 2020 or December 31, 2019.

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 $3.2 million and $10.9 million for the three and nine months ended September 30, 2020, and $4.7 million and $14.7 million for the three and nine months ended September 30, 2019, 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 10, "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 September 30, 2020 and December 31, 2019.

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.

We closely monitor the financial status of our banking credit providers. We evaluate the financial status of our banking partners through the use of market-based metrics such as credit default swap pricing levels, and also through traditional credit ratings provided by major credit rating agencies.

Although certain individual state regulatory commissions have instituted regulatory moratoriums in connection with COVID-19 that continue to impact our ability to pursue our credit risk mitigation practices for customer accounts receivable, we believe this to be temporary, and we expect to reinstate our common credit mitigation practices upon expiration of the state specific moratoriums. See the COVID-19 discussion in the introduction to the "Executive Summary" for risks that have been identified related to COVID-19 and refer to Note 9, "Regulatory Matters" in the Notes to Condensed Consolidated Financial Statements (unaudited) for state specific regulatory moratoriums.
