Description of Business
DPL is a regional energy company organized in 1985 under the laws of Ohio. DPL has 1 reportable segment: the Utility segment. See Note 1110 – Business Segments for more information relating to this reportable segment. The terms “we,” “us,” “our” and “ours” are used to refer to DPL and its subsidiaries.

DPL is an indirectly wholly-owned subsidiary of AES.

DP&L, a wholly-owned subsidiary of DPL that does business as AES Ohio, is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave Ohio consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, retail transmission and distribution services are still regulated. DP&LAES Ohio has the exclusive right to provide such transmission and distribution services to approximately 528,000532,000 customers located in West Central Ohio. Additionally, DP&LAES Ohio provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. AES Ohio sources all of the generation for its SSO customers through a competitive bid process. Principal industries located in DP&L’sAES Ohio’s service territory include automotive, food processing, paper, plastic, health care, data management, manufacturing and defense. DP&L's AES Ohio'ssales typically reflect the general economic conditions, seasonal weather patterns of the area and the growthmarket price of energy efficiency initiatives. However,electricity. AES Ohio owned interests in the impacts of weather, energy efficiency programsretired Hutchings Coal Station until its transfer in 2020, and economic changes in customer demand were largely offset in 2019 bycurrently owns numerous transmission facilities. DP&L’s Decoupling Rider, which was in place from January 1, 2019 until December 18, 2019.See Note 3 – Regulatory Matters for more information.

DPL also has a wholly-owned business trust, DPL Capital Trust II, formed for the purpose of issuing trust capital securities to investors.

DP&L’sAES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, DP&LAES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses and records regulatory assets when incurred costs are expected to be recovered in future customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs.

DPL and its subsidiaries employed 644 people ascosts or overcollections of June 30, 2020, of which 643 were employed by DP&L. Approximately 58% of all DPL employees are under a collective bargaining agreement, which expires October 31, 2020.riders.

The preparation of financial statements in conformity with GAAP requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the revenues and expenses of the periods reported. Actual results could differ from these estimates. Significant items subject to such estimates and judgments include: recognition of revenue including unbilled revenues, the carrying value of property, plant and equipment; the valuation of derivative instruments; the valuation of insurance and claims liabilities; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; liabilities recorded for income tax exposures; litigation; contingencies; the valuation of AROs; and assets and liabilities related to employee benefits.

On January 1, 2020, we adopted ASC 326 Financial Instruments - Credit Losses and its subsequent corresponding updates ("ASC 326"). The new standard updates the impairment model for financial assets measured at amortized cost, known as the Current Expected Credit Loss ("CECL") model. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities are required to use a new forward-looking "expected loss" model that generally results in the earlier recognition of an allowance for credit losses. For available-for-sale debt securities with unrealized losses, entities measure credit losses as it was done under previous GAAP, except that unrealized losses due to credit-related factors are now recognized as an allowance on the balance sheet with a corresponding adjustment to earnings in the income statement.

We applied the modified retrospective method of adoption for ASC 326. Under this transition method, we applied the transition provisions starting at the date of adoption. The new current expected credit loss model primarily impacts the calculation of expected credit losses on our trade accounts receivable. The adoption of ASC 326 and application

The allowance for credit losses primarily relates to utility customer receivables, including unbilled amounts. Expected credit loss estimates are developed by disaggregating customers into those with similar credit risk characteristics and using historical credit loss experience. In addition, we also consider how current and future economic conditions are expected to impact collectability, as applicable, including the economic impacts of the COVID-19 pandemic on our receivable balance as of June 30, 2020.March 31, 2021. Amounts are written off when reasonable collections efforts have been exhausted. On March 12, 2020, the PUCO issued an emergency order prohibiting electric utilities, including us, from discontinuing electric utility service to customers. This order along with the economic impacts of COVID-19 has resulted in an increase in past due customer receivable balances, and thusDuring 2021, the current period provision and the allowance for credit losses have increased during the second quarter of 2020.decreased due to lower past due customer receivable balances. See Note 1413 – Risks and Uncertainties for additional discussion of the COVID-19 pandemic.

DP&L ESP Ordersand SEET Proceedings
On October 23, 2020, AES Ohio law requires utilities entered into a Stipulation and Recommendation (settlement) with the staff of the PUCO and various customers, and organizations representing customers of AES Ohio and certain other parties with respect to, file either an ESP or MROamong other matters, AES Ohio's applications pending at the PUCO for (i) approval of AES Ohio's plan to establish SSO rates. From Novembermodernize its distribution grid (the Smart Grid Plan), (ii) findings that AES Ohio passed the SEET for 2018 and 2019, and (iii) findings that AES Ohio's current ESP 1 2017 through December 18, 2019, DP&L operated pursuant to an approved ESP plan, which was initially approved on October 20, 2017 (ESP 3). On November 21, 2019,satisfies the PUCO issued a supplemental order modifying ESP 3,SEET and as a result DP&L filed a Notice of Withdrawal of its ESP 3 Application and requested to revert to the ESP rates that were in effect prior to ESP 3. The Notice of Withdrawal was approved by the PUCO on December 18, 2019. The PUCO order required, among other things, DP&L to conduct both an ESP v. MRO Test to validate that the ESP is expected to be more favorable in the aggregate than what would be experienced under an MRO, and a prospective SEET, which were filed with the PUCO on April 1, 2020. A comment period was set for July 2020 and an evidentiary hearing regarding this matter(MFA) regulatory test. The settlement is scheduled for October 2020 (if needed) with a final ruling expected in early 2021. DP&L is also subject to, an annual retrospective SEET. The ultimate outcomeand conditioned upon, approval by the PUCO. A hearing was held in January 2021 for consideration of the ESP v. MRO and SEET proceedings could havethis settlement; a material adverse effect on DP&L’s results of operations, financial condition and cash flows.commission order is pending.

Certain parties which intervened in the ESP proceedings have filed petitions for rehearing of the recent PUCO ESP orders; some of which seek to eliminate DP&L’s RSC from the ESP 1 rates that are currently in place and others seek to re-implement the 2017 ESP, but without the DMR. We are unable to predict the outcomes of these petitions, but if these result in terms that are more adverse than DP&L's current ESP rate plan, it could have a material adverse effect on our results of operations, financial condition and cash flows.

Decoupling
On January 23, 2020 DP&LAES Ohio filed with the PUCO requesting approval to defer its decoupling costs consistent with the methodology approved in its Distribution Rate Case. If approved, deferral would be effective December 18, 2019 and going forward would reduce impacts of weather, energy efficiency programs and economic changes in customer demand. An evidentiary hearing was held on this matter on May 4, 2021.

FERC Proceedings
On November 15, 2018 the FERC issued a Notice of Proposed Rulemaking (NOPR) to address amortization of excess accumulated deferred income taxes resulting from the TCJA and their impact on transmission rates. Such notice requires all public utility transmission providers with stated transmission rates under an Open Access Transmission Tariff (OATT) to determine the amount of excess deferred income taxes caused by the TCJA. On March 3, 2020, DP&LAES Ohio filed an application before the FERC to change its transmission rate from a stated rate to a formula rate, which was accepted by the FERC and made effective as of May 3, 2020, subject to further proceeding and potential refunds. The formulaAn uncontested settlement was filed December 10, 2020, which would increase the rates that were in effect prior to the filing but are a reduction from the rate includes adjustments to flow back over time the excess deferred income taxes caused by the TCJA. The NOPR, therefore, no longer applies to DP&L. The rate changes will increase revenues by approximately $4.1 million through the end of 2020 as of thethat became effective date, subject to refund based on finalMay 3, 2020. Among other things, the settlement establishes new depreciation rates for our transmission assets and an authorized return on equity (ROE) of 9.85%, which would rise to 9.99% if the FERC were to approve in a separate ongoing proceeding a return on equity “adder” to recognize our continued membership in PJM. The 9.85% ROE (base) and 9.99% ROE (base + incentive) levels are subject to a four-year moratorium on other proposed ROE changes. Proposals to raise or lower the ROE could be filed with an effective date after the moratorium expires on April 14, 2025. The required flowback of excess deferred taxes under the NOPR was also addressed and resolved as part of this formula transmission rate settlement. On April 15, 2021, the FERC approved rates.the transmission rate settlement.

Note 4 – Fair Value

The fair value of current financial assets and liabilities, debt service reserves and other deposits approximate their reported carrying amounts. The estimated fair values of our assets and liabilities have been determined using available market information. By virtue of these amounts being estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

Table of Contents
Level 1 inputs are used for money market accounts that are considered cash equivalents. The fair value is determined by reference to quoted market prices and other relevant information generated by market transactions.
Level 2 inputs are used to value derivatives such as interest rate hedge contracts which are valued using a benchmark interest rate. Other Level 2 assets include open-ended mutual funds in the Master Trust, which are valued using the end of day NAV per unit.
Level 3 inputs such as certain debt balances are considered a Level 3 input because the notes are not publicly traded. Our long-term debt is fair valued for disclosure purposes only.

All of the inputs to the fair value of our derivative instruments are from quoted market prices.

Our long-term debt is fair valued for disclosure purposes only and most of the fair values are determined using quoted market prices in inactive markets. These fair value inputs are considered Level 2 in the fair value hierarchy. As the Wright-Patterson Air Force Base note is not publicly traded, the fair value inputs are considered Level 3 in the fair value hierarchy as there are no observable inputs. Additional Level 3 disclosures are not presented since our long-term debt is not recorded at fair value.

Note 5 – Derivative Instruments and Hedging Activities

In the normal course of business, DPL enters into various financial instruments, including derivative financial instruments. We use derivatives principally to manage the interest rate risk associated with our long-term debt. The derivatives that we use to economically hedge these risks are governed by our risk management policies for forward and futures contracts. Our net positions are continually assessed within our structured hedging programs to determine whether new or offsetting transactions are required. We monitor and value derivative positions monthly as part of our risk management processes. We use published sources for pricing, when possible, to mark positions to market. All ofFor further information on our derivative instruments are used for risk management purposes and are designated as cash flow hedges if they qualify under FASC 815 forhedge accounting purposes.policies, See Note 1 – Overview and Summary of Significant Accounting Policies – Financial Derivatives and Note 6 - Derivative Instruments and Hedging Activities of Item 8 – Financial Statements and Supplementary Data in our Form 10-K.

Cash Flow Hedges
As part of our risk management processes, we identifyIn August 2020, the relationships between hedging instruments and hedged items, as well as the risk management objective and strategy for undertaking various hedge transactions. The fair values of cash flow hedges determined by current public market prices will continue to fluctuate with changes in market prices up to contract expiration. With the adoption of ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted improvements to Accounting for Hedging Activities effective January 1, 2019, we are no longer required to calculate effectiveness and thus the entire change in the fair value of a hedging instrument is recorded in other comprehensive income and amounts deferred will be reclassified to earnings in the same income statement line as the hedged item in the period in which it settles.

As of June 30, 2020, we have 2 interest rate swaps to hedge the variable interest on ourthe $140.0 million variable interest rate tax-exempt First Mortgage Bonds.Bonds expired, as the associated debt reached maturity. The interest rate swaps havehad a combined notional amount of $140.0 million and settlesettled monthly based on a one-month LIBOR. The AOCL associated with the swaps will bewas amortized out of AOCL into interest expense over the remaining life of the underlying debt.

We also had previously entered into interest rate derivative contracts to manage interest rate exposure related to anticipated borrowings of fixed-rate debt. These interest rate derivative contracts were settled in 2013 and we continue to amortize amounts out of AOCIAOCL into interest expense.

Income tax expense for the six months ended June 30, 2020 and 2019 was calculated using the estimated annual effective income tax rates for 2020 and 2019 of 71.1% and 12.3%, respectively. Management estimates the annual effective tax rate based on its forecast of annual pre-tax income. To the extent that actual pre-tax results for the year differ from the forecasts applied to the most recent interim period, the estimated rates could be materially different from the actual effective tax rates. DPL’s effective combined state and federal income tax rate for all operations was 50.0% and 37.2%(3.8)% for the three and six months ended June 30, 2020, respectively.March 31, 2021. This rate is higher thandifferent from the combined federal and state statutory rate of 22.3%22.5% primarily due to the flowthrough of the net tax benefit related to the reversal of excess deferred taxes of DP&LAES Ohio and the reversalas a percentage of an uncertain tax position; these were partially offset by an adjustment to our deferred tax balances.pre-tax book income.

AES files federal and state income tax returns which consolidate DPL and its subsidiaries. Under a tax sharing agreement with AES, DPL is responsible for the income taxes associated with its own taxable income and records the provision for income taxes using a separate return method. Effective with the approval of DP&L's 2017 ESP, through November 21, 2019, DPL was restricted from making tax sharing payments to AES throughout the term of the DMR and amounts that would otherwise have been tax sharing liabilities were converted to deemed capital contributions. With the November 21, 2019 order from the PUCO that removed the DMR, this requirement was eliminated. During the six months ended June 30, 2020, DPL received a payment from AES of $52.0 million against its tax receivable balance as part of a $150.0 million payment from AES. See Note 9 – Shareholder's Deficit for additional information.

Note 8 – Benefit Plans

DP&LAES Ohio sponsors a defined benefit pension plan for the majority of its employees.

We generally fund pension plan benefits as accrued in accordance with the minimum funding requirements of ERISA and, in addition, make voluntary contributions from time to time. There were $9.8 million and $7.5 million in employer contributions during each of the six-month periodsthree months ended June 30,March 31, 2021 and 2020, and 2019.respectively.

In addition, DP&LAES Ohio provides postretirement health care and life insurance benefits to certain retired employees, their spouses and eligible dependents. We have funded a portion of the union-eligible benefits using a Voluntary Employee Beneficiary Association Trust. These postretirement health care benefits and the related unfunded obligation of $9.6$8.8 million at June 30, 2020March 31, 2021 and $9.6$9.0 million at December 31, 20192020 were not material to the financial statements in the periods covered by this report.

Note 9 – Shareholder's Deficit

Capital Contributions from AES
In DP&L's six-year 2017 ESP, the PUCO imposed restrictions on DPL making dividend payments to its parent company, AES, during the term of the ESP, as well as on making tax-sharing payments to AES during the term of the DMR. The PUCO also required that existing tax payments owed by DPL to AES, and similar tax payments that accrue during the term of the DMR, be converted into equity investments in DPL. With the November 21, 2019 order from the PUCO that removed the DMR and the subsequent approval of DP&L's ESP 1 rate plan, these requirements were eliminated. See Note 3 – Regulatory Matters in Item 8. — Financial Statements and Supplementary Data of our Form 10-K for additional information on changes to DP&L's ESP and the removal of the DMR.

Table of Contents
For the six months ended June 30, 2019, DPL had a current tax benefit. Consequently, there was no conversion of current tax liabilities to AES capital contributions for the six months ended June 30, 2019.

During the six months ended June 30, 2020, DPL received $150.0 million in a cash contribution from AES, which DPL then used to make a $150.0 million capital contribution to DP&L. The contribution at DPL represented an equity capital contribution of $98.0 million and a payment of $52.0 million against its tax receivable. The proceeds from the capital contribution at DP&L will primarily be used for funding needs to support DP&L's capital expenditure program, mainly new investments in and upgrades to DP&L’s transmission and distribution system.

Note 109 – Contractual Obligations, Commercial Commitments and Contingencies

Guarantees
In the normal course of business,Previously, DPL entersentered into various agreements with its wholly-owned subsidiary, AES Ohio Generation, providing financial or performance assurance to third parties. These agreements arewere entered into primarily to support or enhance the creditworthiness otherwise attributed to thisthe subsidiary on a stand-alone basis, thereby facilitating the extension of sufficient credit to accomplish this subsidiary's intended commercial purposes.

At With the completion of our plan to exit generation, AES Ohio Generation currently does not require such assurances to third parties, and existing guarantees will expire in June 30, 2020,2021. During the three months ended March 31, 2021, DPL had $11.9 million of guarantees on behalf of AES Ohio Generation to third parties for future financial or performance assurance under such agreements. The guarantee arrangements entered into by DPL with these third parties cover select present and future obligations of AES Ohio Generation to such beneficiaries and are terminable by DPL upon written notice to the beneficiaries within a certain time. At June 30, 2020 and December 31, 2019, we had no outstanding balance of obligations covered by these guarantees.

To date, DPL hasdid not incurredincur any losses related to the guarantees of AES Ohio Generation’sthese obligations, and we believe it is unlikely that DPL would be required to perform or incur any losses in the future associated with any of the above guarantees. At March 31, 2021, DPL had $1.9 million of such guarantees on behalf of AES Ohio Generation. There were no outstanding balances for commercial transactions covered by these guarantees at March 31, 2021 or December 31, 2020.

Equity Ownership Interest
DP&LAES Ohio has a 4.9% equity ownership interest in OVEC, which is recorded using the cost method of accounting under GAAP. DP&LAES Ohio, along with several non-affiliated energy companies party to an OVEC arrangement, receive and pay for OVEC capacity and energy and are responsible for OVEC debt obligations and other fixed costs in proportion to their power participation ratios under the arrangement, which, for DP&L,AES Ohio, is the same as its equity ownership interest. At June 30, 2020,March 31, 2021, DP&LAES Ohio could be responsible for the repayment of 4.9%, or $64.0$62.0 million, of $1,306.0$1,264.5 million OVEC debt obligations if they came due, comprised of both fixed and variable rate securities with maturities from 2022 to 2040. OVEC could also seek additional contributions from DP&LAES Ohio to avoid a default in the event that other OVEC members defaulted on their respective OVEC obligations. One of the other OVEC members had filed for bankruptcy protection and the bankruptcy court had approved that member's rejection of the OVEC arrangement and its related obligations. Subsequent to that decision, another entity has assumed that member's ownership interest and all related liabilities.

Contingencies
In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under various laws and regulations. We believe the amounts provided in our Condensed Consolidated Financial Statements, as prescribed by GAAP, are adequate considering the probable and estimable contingencies. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various legal proceedings, claims, tax examinations and other matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in our Condensed Consolidated Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided as of June 30, 2020,March 31, 2021, cannot be reasonably determined.

Environmental Matters
DPL’s and DP&L’sAES Ohio’s current and previously-owned facilities and operations are subject to a wide range of federal, state and local environmental regulations and laws. The environmental issues that may affect us include:

The federal CAA and state laws and regulations (including State Implementation Plans) which require compliance, obtaining permits and reporting as to air emissions;
Litigation with federal and certain state governments and certain special interest groups;groups regarding whether modifications to or maintenance of certain coal-fired generating stations require additional permitting or pollution control technology, or whether emissions from coal-fired generating stations cause or contribute to global climate changes;
Rules and future rules issued by the USEPA, the Ohio EPA or other authorities that require or will require substantial reductions in SO2, particulates, mercury, acid gases, NOx and other air emissions;
Rules and future rules issued by the USEPA, the Ohio EPA or other authorities that require or will require reporting and reductions of GHGs;
2423

Table of Contents
Rules and future rules issued by the USEPA, the Ohio EPA or other authorities associated with the federal Clean Water Act, which prohibits the discharge of pollutants into waters of the United States except pursuant to appropriate permits; and
Solid and hazardous waste laws and regulations, which govern the management and disposal of certain waste. The majority of solid waste created from the combustion of coal and fossil fuels consists of fly ash and other coal combustion by-products.

In addition to imposing continuing compliance obligations, these laws and regulations authorize the imposition of substantial penalties for noncompliance, including fines, injunctive relief and other sanctions. In the normal course of business, we have investigatory and remedial activities underway at our facilities to comply, or to determine compliance, with such regulations. We record liabilities for loss contingencies related to environmental matters when a loss is probable of occurring and can be reasonably estimated in accordance with the provisions of GAAP. Accordingly, we have immaterial accruals for loss contingencies for environmental matters. We also have several environmental matters for which we have not accrued loss contingencies because the risk of loss is not probable, or a loss cannot be reasonably estimated. We evaluate the potential liability related to environmental matters quarterly and may revise our estimates. Such revisions in the estimates of the potential liabilities could have a material adverse effect on our results of operations, financial condition and cash flows.

We have several pending environmental matters associated with our previously-owned and operated coal-fired generation units. Some of these matters could have a material adverse effect on our results of operations, financial condition and cash flows.

Note 1110 – Business Segments

DPL manages its business through 1 reportable operating segment, the Utility segment. The primary segment performance measure is income / (loss) from continuing operations before income tax as management has concluded that this measure best reflects the underlying business performance of DPL and is the most relevant measure considered in DPL’s internal evaluation of the financial performance of its segment. The Utility segment is discussed further below.

Utility Segment
The Utility segment is comprised of DP&L’sAES Ohio’s electric transmission and distribution businesses, which distribute electricity to residential, commercial, industrial and governmental customers. DP&LAES Ohio distributes electricity to more than 528,000approximately 532,000 retail customers located in a 6,000-square mile area of West Central Ohio. DP&L’sAES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, DP&LAES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses recording regulatory assets when incurred costs are expected to be recovered in future customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs. The Utility segment includes revenues and costs associated with our investment in OVEC and the historical results of DP&L’sAES Ohio’s Hutchings Coal generating facility,Station, which was closed in 2013. This facility did not transfer2013 and transferred to AES Ohio Generation as part of DP&L's Generation Separation on October 1, 2017. Thus, it is grouped within the Utility segment for segment reporting purposes. In addition, regulatory deferrals and collections, which include collections and amortization of fuel deferrals from historical periods, are includeda third party in the Utility segment.fourth quarter of 2020.

Included within the “Other” column are other businesses that do not meet the GAAP requirements for disclosure as reportable segments as well as certain corporate costs, which include interest expense and loss on early extinguishment of debt on DPL's long-term debt as well as adjustments related to purchase accounting from the Merger. The accounting policies of the reportable segment are the same as those described in Note 1 – Overview and Summary of Significant Accounting Policies of our 10-K. Intersegment sales, costs of sales and expenses are eliminated in consolidation. Certain shared and corporate costs are allocated between "Other" and the Utility reporting segment.

Note 1211 – Revenue

Revenue is primarily earned from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities. For further discussion of our Retail, Wholesale, RTO ancillary, and Capacity revenues, see Note 14 — Revenue in Item 8.—Financial Statements and Supplementary Data of our Form 10-K.

DPL's revenue from contracts with customers was $148.3$172.1 million and $168.6$167.0 million for the three months ended June 30,March 31, 2021 and 2020, and 2019, respectively, and $315.3 million and $371.9 million for the six months ended June 30, 2020 and 2019, respectively.

Note 1312 – Discontinued Operations

Conesville - In May 2020, AEP, the operator of the formerly co-owned Conesville EGU, retired Conesville Unit 4 as planned. On JuneJune 5, 2020, DPL and AES Ohio Generation, together with AEP, completed the transfer of their interests in the retired Unit 4, including the associated environmental liabilities, to an unaffiliated third-party purchaser. As a result, DPL made cash expenditures of $0.6 million and recognized a gain on the transfer of $4.5 million for the three and six months ended June 30, 2020. For the transaction, DPL will make additional quarterly cash expenditures, totaling $3.4$4.0 million, through July 2022.2022,

of which $2.2 million has been paid through March 31, 2021. The transfer of Conesville Unit 4 was the last step in DPL's plan to exit its AES Ohio Generation business operations.

Stuart and Killen - On May 31, 2018, DPL and AES Ohio Generation retired the Stuart Station coal-fired and diesel-fired generating units and the Killen Station coal-fired generating unit and combustion turbine, as planned. On December 20, 2019, DPL and AES Ohio Generation, together with AES Ohio Generation's joint owners in the retired Stuart and Killen generating facilities, completed the transfer of the retired generating facilities, including the associated environmental liabilities, to an unaffiliated third-party purchaser.

DPL determined that the transfer of Conesville along with the transfers of Conesville, Stuart and Killen along within 2019 and the sales of the Peaker Assets in 2018 and Miami Fort and Zimmer in 2017 constitute the disposal of a group of components, which, as a whole, represent a strategic shift to exit its AES Ohio Generation business. As such, the disposal of this group of components qualifies to be presented as discontinued operations. Therefore, the results of operations assets and liabilities of this group of components were reported as such in the Condensed Consolidated Statements of Operations and Condensed Consolidated Balance Sheets for all periods presented.

Cash flows from operating activities for discontinued operations were $(2.7)$(0.2) million and $6.8$6.2 million for the three months ended June 30,March 31, 2021 and 2020, and 2019, respectively, and $3.6 million and $11.6 million for the six months ended June 30, 2020 and 2019, respectively. Cash flows from investing activities for discontinued operations were $(0.6)$(0.4) million and $4.4$5.1 million respectively, for the three and six months ended June 30, 2020. There were no material cash flows from investing activities for the threeMarch 31, 2021 and six months ended June 30, 2019.

AROs of Discontinued Operations
Prior to the transfer of the retired Stuart and Killen generating facilities, the facilities carried ARO liabilities consisting primarily of river intake and discharge structures, coal unloading facilities, landfills and ash disposal facilities. In the first quarter of 2019, DPL reduced the ARO liability related to the Stuart and Killen ash ponds and landfills by $22.5 million based on updated internal analyses that reduced estimated closure costs associated with these ash ponds and landfills. As these plants were no longer in service, the reduction to the ARO liability was recorded as a credit to depreciation and amortization expense in the same amount. The credit to depreciation and amortization expense is included in operating and other expenses of discontinued operations for the six months ended June 30, 2019 in the table above.2020, respectively.

Note – 1413 Risks and Uncertainties

COVID-19 Pandemic

The COVID-19 pandemic has severely impacted global economic activity, including electricity and energy consumption, and caused significant volatility and negative pressure in financial markets. The global impact of the outbreak has been rapidly evolving and many countries, including the United States,U.S., have reacted by instituting quarantines, mandating business and school closures and social distancing measures as well as restricting travel. TheResponses to the COVID-19 pandemic by the State of Ohio has implemented, among other things, stay-at-homeand its residents and businesses, in particular, continue to evolve, including with respect to business and school closures and limitations and other social distancing measures and the effectiveness and timing of vaccine availability and distribution efforts. Social distancing measures designed to slow the spread of the virus, which has resulted in decreasedsuch as business closures and operations limitations, impact energy demand within our service territory, though these stay-at-home restrictions have now been lifted in our service territory. On March 12, 2020, the PUCO also issued an emergency order prohibiting electric utilities, including us, from discontinuing electric utility service to customers. This prohibition is currently scheduled to end for DP&L on September 1, 2020, pending approval by the PUCO. We are taking a variety of measures in response to the spread of COVID-19 to ensure our ability to transmit, distribute and sell electric energy, ensure the health and safety of our employees, contractors, customers and communities and provide essential services to the communities in which we operate. In addition to reduced revenues and lower margins resulting from decreased energythe impacts to demand within our service territory, we also have incurred and expect to continue to incur expenses relating to COVID-19, and such expenses may includeincluding those that relate to events outside of our control.

For the three and six months ended June 30, 2020, the COVID-19 pandemic primarily impacted our retail sales demand, as the economic impact of the pandemic started to materialize in Ohio in the second half of March 2020 and more so in the second quarter of 2020. For commercial and industrial customers, weather-normalized volumes of kWh sold decreased by 11.0% and 19.9%, respectively, for the three months ended June 30, 2020 as compared to the same period in the prior year. For residential customers, weather-normalized volumes of kWh sold increased by 8.5% for the three months ended June 30, 2020 as compared to the same period in the prior year. We also have incurred, and expect to continue to incur, expenses relating to COVID-19; however, see Note 3 – Regulatory Matters for a discussion of regulatory measures, which partially mitigate the impact of these expenses. The magnitude and duration of the COVID-19 pandemic is unknown at this time and may have material and adverse effects on our results of operations, financial condition and cash flows in future periods.

Note 1 – Overview and Summary of Significant Accounting Policies

Description of Business
DP&L, which does business as AES Ohio, is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave Ohio consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, retail transmission and distribution services are still regulated. DP&LAES Ohio has the exclusive right to provide such transmission and distribution services to approximately 528,000532,000 customers located in West Central Ohio. Additionally, DP&LAES Ohio provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. DP&L has 1 reportable segment, the Utility segment. In addition to DP&L'sAES Ohio electric transmission and distribution businesses,sources all of the Utility segment includes revenues and costs associated with DP&L's investment in OVEC and the historical results of DP&L’s Hutchings Coal generating facility, which is now closed.generation for its SSO customers through a competitive bid process. Principal industries located in DP&L’sAES Ohio’s service territory include automotive, food processing, paper, plastic, health care, data management, manufacturing and defense. DP&L's AES Ohio'ssales typically reflect the general economic conditions, seasonal weather patterns of the area and the growthmarket price of energy efficiency initiatives. However,electricity. AES Ohio owned interests in the impacts of weather, energy efficiency programsretired Hutchings Coal Station until its transfer in 2020, and economic changes in customer demand were largely offset in 2019 bycurrently owns numerous transmission facilities. DP&L’s Decoupling Rider, which was in place from January 1, 2019 until December 18, 2019.See Note 3 – Regulatory Matters for more information. DP&LAES Ohio sells its proportional share of energy and capacity from its investment in OVEC into the wholesale market.AES Ohio has 1 reportable segment, the Utility segment.

Financial Statement Presentation
DP&LAES Ohio does not have any subsidiaries.

We have evaluated subsequent events through the date this report is issued.

Certain immaterial amounts from prior periods have been reclassified to conform to the current period presentation.

These financial statements have been prepared in accordance with GAAP, as contained in the FASB ASC, for interim financial statements and Article 10 of Regulation S-X issued by the instructions of Form 10-Q and Regulation S-X.SEC. Accordingly, certainthey do not include all the information and footnote disclosures normally included in thefootnotes required by GAAP for annual financial statements prepared in accordance with GAAP have been omitted from this interim report.fiscal reporting periods. Therefore, our interim financial statements in this report should be read along with the annual financial statements included in our Form 10-K for the fiscal year ended December 31, 2019.2020.

In the opinion of our management, the Condensed Financial Statements presented in this report contain all adjustments necessary to fairly state our financial position as of June 30, 2020;March 31, 2021; our results of operations for the three and six months ended June 30,March 31, 2021 and 2020, and 2019, our cash flows for the sixthree months ended June 30,March 31, 2021 and 2020 and 2019 and the changes in our equity for the three and six months ended June 30, 2020March 31, 2021 and 2019.2020. Unless otherwise noted, all adjustments are normal and recurring in nature. Due to various factors, interim results for the three and six months ended June 30, 2020March 31, 2021 may not be indicative of our results that will be realized for the full year ending December 31, 2020.2021.

The preparation of financial statements in conformity with GAAP requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the revenues and expenses of the periods reported. Actual results could differ from these estimates. Significant items subject to such estimates and judgments include: recognition of revenue including unbilled revenues, the carrying value of property, plant and equipment; the valuation of derivative instruments; the valuation of insurance and claims liabilities; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and

On January 1, 2020, we adopted ASC 326 Financial Instruments - Credit Losses and its subsequent corresponding updates ("ASC 326"). The new standard updates the impairment model for financial assets measured at amortized cost, known as the Current Expected Credit Loss ("CECL") model. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities are required to use a new forward-looking "expected loss" model that generally results in the earlier recognition of an allowance for credit losses. For available-for-sale debt securities with unrealized losses, entities measure credit losses as it was done under previous GAAP, except that unrealized losses due to credit-related factors are now recognized as an allowance on the balance sheet with a corresponding adjustment to earnings in the income statement.

We applied the modified retrospective method of adoption for ASC 326. Under this transition method, we applied the transition provisions starting at the date of adoption. The new current expected credit loss model primarily impacts the calculation of expected credit losses on our trade accounts receivable. The adoption of ASC 326 and application of CECL on our trade accounts receivable did not have a material impact on our condensed financial statements.

The allowance for credit losses primarily relates to utility customer receivables, including unbilled amounts. Expected credit loss estimates are developed by disaggregating customers into those with similar credit risk characteristics and using historical credit loss experience. In addition, we also consider how current and future economic conditions are expected to impact collectability, as applicable, including the economic impacts of the COVID-19 pandemic on our receivable balance as of June 30, 2020.March 31, 2021. Amounts are written off when reasonable collections efforts have been exhausted. On March 12, 2020, the PUCO issued an emergency order prohibiting electric utilities, including us, from discontinuing electric utility service to customers. This order along with the economic impacts of COVID-19 has resulted in an increase in past due customer receivable balances, and thusDuring 2021, the current period provision and the allowance for credit losses

Note 3 – Regulatory Matters

DP&L ESP Ordersand SEET Proceedings
On October 23, 2020, AES Ohio law requires utilities entered into a Stipulation and Recommendation (settlement) with the staff of the PUCO and various customers, and organizations representing customers of AES Ohio and certain other parties with respect to, file either an ESP or MROamong other matters, AES Ohio's applications pending at the PUCO for (i) approval of AES Ohio's plan to establish SSO rates. From Novembermodernize its distribution grid (the Smart Grid Plan), (ii) findings that AES Ohio passed the SEET for 2018 and 2019, and (iii) findings that AES Ohio's current ESP 1 2017 through December 18, 2019, DP&L operated pursuant to an approved ESP plan, which was initially approved on October 20, 2017 (ESP 3). On November 21, 2019,satisfies the PUCO issued a supplemental order modifying ESP 3,SEET and as a result DP&L filed a Notice of Withdrawal of its ESP 3 Application and requested to revert to the ESP rates that were in effect prior to ESP 3. The Notice of Withdrawal was approved by the PUCO on December 18, 2019. The PUCO order required, among other things, DP&L to conduct both an ESP v. MRO Test to validate that the ESP is expected to be more favorable in the aggregate than what would be experienced under an MRO, and a prospective SEET, which were filed with the PUCO on April 1, 2020. A comment period was set for July 2020 and an evidentiary hearing regarding this matter(MFA) regulatory test. The settlement is scheduled for October 2020 (if needed) with a final ruling expected in early 2021. DP&L is also subject to, an annual retrospective SEET.

MRO and SEET proceedings could havethis settlement; a material adverse effect on DP&L’s results of operations, financial condition and cash flows.commission order is pending.

Certain parties which intervened in the ESP proceedings have filed petitions for rehearing of the recent PUCO ESP orders; some of which seek to eliminate DP&L’s RSC from the ESP 1 rates that are currently in place and others seek to re-implement the 2017 ESP, but without the DMR. We are unable to predict the outcomes of these petitions, but if these result in terms that are more adverse than DP&L's current ESP rate plan, it could have a material adverse effect on our results of operations, financial condition and cash flows.

Decoupling
On January 23, 2020 DP&LAES Ohio filed with the PUCO requesting approval to defer its decoupling costs consistent with the methodology approved in its Distribution Rate Case. If approved, deferral would be effective December 18, 2019 and going forward would reduce impacts of weather, energy efficiency programs and economic changes in customer demand. An evidentiary hearing was held on this matter on May 4, 2021.

Distribution Rate Case
On November 30, 2020, AES Ohio filed a new Distribution Rate Case with the PUCO. This rate case proposes a revenue increase of $120.8 million per year and incorporates the DIR investments that were planned and approved in the last rate case but not yet included in distribution rates, other distribution investments since September 2015 and investments necessitated by the tornados that occurred on Memorial Day in 2019. The rate case also includes a proposal for increased tree-trimming expenses and certain customer demand-side management programs and

In response to the PUCO’s COVID-19 emergency orders, DP&L filed an Application on March 23, 2020, requesting waiversrecovery of certain ruleprior-approved regulatory assets for tree trimming, uncollectible expenses and tariff requirements and deferral of certain costs and revenues including those related to deposits and reconnection fees, late payment fees, credit card fees; and waived or uncollected amounts associated with putting customers on payment plans. On May 20, 2020, the PUCO approved the application and required DP&L to filerate case expense. This case is pending a plan outlining the timing and steps it plans to take in an effort to return to normal operations. The authorized deferral of those certain costs and revenues must be offset by COVID-19 related savings. DP&L filed its plan on July 15, 2020 and is awaiting approval by the PUCO. Recovery of these deferrals will be addressed in a future rate proceeding.commission order.

FERC Proceedings
On November 15, 2018 the FERC issued a Notice of Proposed Rulemaking (NOPR) to address amortization of excess accumulated deferred income taxes resulting from the TCJA and their impact on transmission rates. Such notice requires all public utility transmission providers with stated transmission rates under an Open Access Transmission Tariff (OATT) to determine the amount of excess deferred income taxes caused by the TCJA. On March 3, 2020, DP&LAES Ohio filed an application before the FERC to change its transmission rate from a stated rate to a formula rate, which was accepted by the FERC and made effective as of May 3, 2020, subject to further proceeding and potential refunds. The formulaAn uncontested settlement was filed December 10, 2020, which would increase the rates that were in effect prior to the filing but are a reduction from the rate includes adjustments to flow back over time the excess deferred income taxes caused by the TCJA. The NOPR, therefore, no longer applies to DP&L. The rate changes will increase revenues by approximately $4.1 million through the end of 2020 as of thethat became effective date, subject to refund based on finalMay 3, 2020. Among other things, the settlement establishes new depreciation rates for our transmission assets and an authorized return on equity (ROE) of 9.85%, which would rise to 9.99% if the FERC were to approve in a separate ongoing proceeding a return on equity “adder” to recognize our continued membership in PJM. The 9.85% ROE (base) and 9.99% ROE (base + incentive) levels are subject to a four-year moratorium on other proposed ROE changes. Proposals to raise or lower the ROE could be filed with an effective date after the moratorium expires on April 14, 2025. The required flowback of excess deferred taxes under the NOPR was also addressed and resolved as part of this formula transmission rate settlement. On April 15, 2021, the FERC approved rates.the transmission rate settlement.

Note 4 – Fair Value

The fair value of current financial assets and liabilities, debt service reserves and other deposits approximate their reported carrying amounts. The estimated fair values of our assets and liabilities have been determined using available market information. By virtue of these amounts being estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. For further information on our valuation techniques and policies, see Note 5—Fair Value in Item 8. — Financial Statements and Supplementary Data of our Form 10-K.

(a)    Includes credit valuation adjustment

Our financial instruments are valued using the market approach in the following categories:

Level 1 inputs are used for money market accounts that are considered cash equivalents. The fair value is determined by reference to quoted market prices and other relevant information generated by market transactions.
Level 2 inputs are used to value derivatives such as interest rate hedge contracts which are valued using a benchmark interest rate. Other Level 2 assets include open-ended mutual funds in the Master Trust, which are valued using the end of day NAV per unit.
Level 3 inputs such as certain debt balances are considered a Level 3 input because the notes are not publicly traded. Our long-term debt is fair valued for disclosure purposes only.

All of the inputs to the fair value of our derivative instruments are from quoted market prices.

Our long-term debt is fair valued for disclosure purposes only and most of the fair values are determined using quoted market prices in inactive markets. These fair value inputs are considered Level 2 in the fair value hierarchy. As the Wright-Patterson Air Force Base note is not publicly traded, the fair value inputs are considered Level 3 in

the fair value hierarchy as there are no observable inputs. Additional Level 3 disclosures are not presented since our long-term debt is not recorded at fair value.

Note 5 – Derivative Instruments and Hedging Activities

In the normal course of business, DP&L enters into various financial instruments, including derivative financial instruments. We use derivatives principally to manage the interest rate risk associated with our long-term debt. The derivatives that we use to economically hedge these risks are governed by our risk management policies for forward and futures contracts. Our net positions are continually assessed within our structured hedging programs to determine whether new or offsetting transactions are required. We monitor and value derivative positions monthly as part of our risk management processes. We use published sources for pricing, when possible, to mark positions to market. All ofFor further information on our derivative instruments are used for risk management purposes and are designated as cash flow hedges if they qualify under FASC 815 forhedge accounting purposes.policies, See Note 1 – Overview and Summary of Significant Accounting Policies – Financial Derivatives and Note 6 - Derivative Instruments and Hedging Activities of Item 8 – Financial Statements and Supplementary Data in our Form 10-K.

Cash Flow Hedges
As part of our risk management processes, we identifyIn August 2020, the relationships between hedging instruments and hedged items, as well as the risk management objective and strategy for undertaking various hedge transactions. The fair values of cash flow hedges determined by current public market prices will continue to fluctuate with changes in market prices up to contract expiration. With the adoption of ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted improvements to Accounting for Hedging Activities effective January 1, 2019, we are no longer required to calculate effectiveness and thus the entire change in the fair value of a hedging instrument is recorded in other comprehensive income and amounts deferred will be reclassified to earnings in the same income statement line as the hedged item in the period in which it settles.

As of June 30, 2020, we have 2two interest rate swaps to hedge the variable interest on ourthe $140.0 million variable interest rate tax-exempt First Mortgage Bonds.Bonds expired, as the associated debt reached maturity. The interest rate swaps havehad a combined notional amount of $140.0 million and settlesettled monthly based on a one-month LIBOR. The AOCL associated with the swaps will bewas amortized out of AOCL into interest expense over the remaining life of the underlying debt.

Note 10 – Contractual Obligations, Commercial Commitments and Contingencies

Equity Ownership Interest
DP&LAES Ohio has a 4.9% equity ownership interest in OVEC, which is recorded using the cost method of accounting under GAAP. DP&LAES Ohio, along with several non-affiliated energy companies party to an OVEC arrangement, receive and pay for OVEC capacity and energy and are responsible for OVEC debt obligations and other fixed costs in proportion to their power participation ratios under the arrangement, which, for DP&L,AES Ohio, is the same as its equity ownership interest. At June 30, 2020,March 31, 2021, DP&LAES Ohio could be responsible for the repayment of 4.9%, or $64.0$62.0 million, of $1,306.0$1,264.5 million OVEC debt obligations if they came due, comprised of both fixed and variable rate securities with maturities from 2022 to 2040. OVEC could also seek additional contributions from DP&LAES Ohio to avoid a default in the event that other OVEC members defaulted on their respective OVEC obligations. One of the other OVEC members had filed for bankruptcy protection and the bankruptcy court had approved that member's rejection of the OVEC arrangement and its related obligations. Subsequent to that decision, another entity has assumed that member's ownership interest and all related liabilities.

Contingencies
In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under various laws and regulations. We believe the amounts provided in our Condensed Financial
40

Table of Contents
Statements, as prescribed by GAAP, are adequate considering the probable and estimable contingencies. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various legal proceedings, claims, tax examinations and other matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in our Condensed Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided as of June 30, 2020,March 31, 2021, cannot be reasonably determined.

Environmental Matters
DP&L’sAES Ohio’s current and previously-owned facilities and operations are subject to a wide range of federal, state and local environmental regulations and laws. The environmental issues that may affect us include:

The federal CAA and state laws and regulations (including State Implementation Plans) which require compliance, obtaining permits and reporting as to air emissions;
Litigation with federal and certain state governments and certain special interest groups;groups regarding whether modifications to or maintenance of certain coal-fired generating stations require additional permitting or pollution control technology, or whether emissions from coal-fired generating stations cause or contribute to global climate changes;
Rules and future rules issued by the USEPA, the Ohio EPA or other authorities that require or will require substantial reductions in SO2, particulates, mercury, acid gases, NOx and other air emissions;
Rules and future rules issued by the USEPA, the Ohio EPA or other authorities that require or will require reporting and reductions of GHGs;
Rules and future rules issued by the USEPA, the Ohio EPA or other authorities associated with the federal Clean Water Act, which prohibits the discharge of pollutants into waters of the United States except pursuant to appropriate permits; and
Solid and hazardous waste laws and regulations, which govern the management and disposal of certain waste.

In addition to imposing continuing compliance obligations, these laws and regulations authorize the imposition of substantial penalties for noncompliance, including fines, injunctive relief and other sanctions. In the normal course of business, we have investigatory and remedial activities underway at our facilities to comply, or to determine compliance, with such regulations. We record liabilities for loss contingencies related to environmental matters when a loss is probable of occurring and can be reasonably estimated in accordance with the provisions of GAAP. Accordingly, we have immaterial accruals for loss contingencies for environmental matters. We also have several environmental matters for which we have not accrued loss contingencies because the risk of loss is not probable, or a loss cannot be reasonably estimated. We evaluate the potential liability related to environmental matters quarterly and may revise our estimates. Such revisions in the estimates of the potential liabilities could have a material adverse effect on our results of operations, financial condition and cash flows.

Note 11 – Revenue

Revenue is primarily earned from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities. For further discussion of our Retail, Wholesale, RTO ancillary, and Capacity revenues, see Note 13 — Revenue in Item 8.—Financial Statements and Supplementary Data of our Form 10-K.

Note – 12 Risks and Uncertainties

COVID-19 Pandemic

The COVID-19 pandemic has severely impacted global economic activity, including electricity and energy consumption, and caused significant volatility and negative pressure in financial markets. The global impact of the outbreak has been rapidly evolving and many countries, including the United States,U.S., have reacted by instituting quarantines, mandating business and school closures and social distancing measures as well as restricting travel. TheResponses to the COVID-19 pandemic by the State of Ohio has implemented, among other things, stay-at-homeand its residents and businesses, in particular, continue to evolve, including with respect to business and school closures and limitations and other social distancing measures and the effectiveness and timing of vaccine availability and distribution efforts. Social distancing measures designed to slow the spread of the virus, which has resulted in decreasedsuch as business closures and operations limitations, impact energy demand within our service territory, though these stay-at-home restrictions have now been lifted in our service territory. On March 12, 2020, the PUCO also issued an emergency order prohibiting electric utilities, including us, from discontinuing electric utility service to customers. This prohibition is currently scheduled to end for DP&L on September 1, 2020, pending approval by the PUCO. We are taking a variety of measures in response to the spread of COVID-19 to ensure our ability to transmit, distribute and sell electric energy, ensure the health and safety of our employees, contractors, customers and communities and provide essential services to the communities in which we operate. In addition to reduced revenues and lower margins resulting from decreased energythe impacts to demand within our service territory, we also have incurred and expect to continue to incur expenses relating to COVID-19, and such expenses may includeincluding those that relate to events outside of our control.

For the three and six months ended June 30, 2020, the COVID-19 pandemic primarily impacted our retail sales demand, as the economic impact of the pandemic started to materialize in Ohio in the second half of March 2020 and more so in the second quarter of 2020. For commercial and industrial customers, weather-normalized volumes of kWh sold decreased by 11.0% and 19.9%, respectively, for the three months ended June 30, 2020 as compared to the same period in the prior year. For residential customers, weather-normalized volumes of kWh sold increased by 8.5% for the three months ended June 30, 2020 as compared to the same period in the prior year. We also have incurred, and expect to continue to incur, expenses relating to COVID-19; however, see Note 3 – Regulatory

DPL – Revenues
Retail customers, especially residential and commercial customers, consume more electricity on warmer and colder days. Therefore, our retail sales demand is affected by the number of heating and cooling degree-days occurring during a year. Cooling degree-days typically have a more significant effect than heating degree-days since some residential customers do not use electricity to heat their homes. Because of the impact of the Decoupling Rider (effective January 1, 2019 through December 18, 2019), weather had a minimal impact on our 2019 net operating results. Additionally, our retail revenues are affected by regulated rates and riders including the changes to our ESP described in Note 3 - Regulatory Matters of our Form 10-K and Note 3 – Regulatory Matters of Notes to DPL's Condensed Consolidated Financial Statements.

Factors affecting DPL's wholesale sales volume include wholesale market prices; retail demand throughout the entire wholesale market area; unit availability to sell into the wholesale market; and weather conditions.

(a)Heating and cooling degree-days are a measure of the relative heating or cooling required for a home or business. The heating degrees in a day are calculated as the degrees that the average actual daily temperature is below 65 degrees Fahrenheit. For example, if the average temperature on March 20th was 40 degrees Fahrenheit, the heating degrees for that day would be the 25-degree difference between 65 degrees and 40 degrees. Similarly, cooling degrees in a day are calculated as the degrees that the average actual daily temperature is above 65 degrees Fahrenheit.
(b)30-year average is computed from observed degree-days in the Dayton area on a trailing 30-year basis.

RESULTS OF OPERATIONS BY SEGMENT - DPL

DPL manages its business through one reportable operating segment, the Utility segment. The primary segment performance measure is income / (loss) from continuing operations before income tax as management has concluded that this measure best reflects the underlying business performance of DPL and is the most relevant measure considered in DPL’s internal evaluation of the financial performance of its segment. The Utility segment is discussed further below.

Utility Segment
The Utility segment is comprised of DP&L’sAES Ohio’s electric transmission and distribution businesses, which distribute electricity to residential, commercial, industrial and governmental customers. DP&LAES Ohio distributes electricity to more than 528,000approximately 532,000 retail customers located in a 6,000-square mile area of West Central Ohio. DP&L’sAES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, DP&LAES Ohio applies the accounting standards for regulated operations to its electric transmission and distribution businesses recording regulatory assets when incurred costs are expected to be recovered in future

customer rates and regulatory liabilities when current cost recoveries in customer rates relate to expected future costs. The Utility segment includes revenues and costs associated with our investment in OVEC and the historical results of DP&L’sAES Ohio’s Hutchings Coal generating facility,Station, which was closed in 2013. This facility did not transfer2013 and transferred to AES Ohio Generation as part of DP&L's Generation Separation on October 1, 2017. Thus, it is grouped within the Utility segment for segment reporting purposes. In addition, regulatory deferrals and collections, which include collections and amortization of fuel deferrals from historical periods, are includeda third party in the Utility segment.fourth quarter of 2020.

Included within the “Other” column are other businesses that do not meet the GAAP requirements for disclosure as reportable segments as well as certain corporate costs, which include interest expense and loss on early extinguishment of debt on DPL's long-term debt as well as adjustments related to purchase accounting from the Merger. The accounting policies of the reportable segment are the same as those described in Note 1 – Overview and Summary of Significant Accounting Policies of our 10-K. Intersegment sales, costs of sales and expenses are eliminated in consolidation. Certain shared and corporate costs are allocated between "Other" and the Utility reporting segment.

See Part I, Item 1, Note 1110 – Business Segments of Notes to DPL's Condensed Consolidated Financial Statements for additional information regarding DPL’s reportable segment.

DP&LAES Ohio – Revenues
Retail customers, especially residential and commercial customers, consume more electricity on warmer and colder days. Therefore, our retail sales demand is affected by the number of heating and cooling degree-days occurring during a year. Cooling degree-days typically have a more significant effect than heating degree-days since some residential customers do not use electricity to heat their homes. Because of the impact of the Decoupling Rider (effective January 1, 2019 through December 18, 2019), weather had a minimal impact on our 2019 net operating results. Additionally, our retail revenues are affected by regulated rates and riders including the changes to our ESP described in Note 3 - Regulatory Matters of our Form 10-K and Note 3 – Regulatory Matters of Notes to DP&L'sAES Ohio's Condensed Financial Statements.

KEY TRENDS AND UNCERTAINTIES

FollowingDuring the issuanceremainder of the DRO in September 20182021 and the resulting changes to the Decoupling Rider effective January 1, 2019, our financial results were not driven by retail demand and weather but were impacted by customer growth within our service territory. However, the Decoupling Rider was removed with the approved withdrawal of the 2017 ESP and reversion to DP&L's ESP 1 rate plan in December 2019. As such,beyond, we expect our results are againwill be primarily impacted by retail demand and weather. As discussed in Note 3 – Regulatory Mattersof Notes to DPL's Condensed Consolidated Financial Statements and Note 3 – Regulatory Matters of Notes to AES Ohio's Condensed Financial Statements in Part I, Item 1 of this report, AES Ohio has requested PUCO approval to defer its decoupling costs consistent with the methodology approved in its DRO. If approved, the deferral would be effective as of December 18, 2019 and going forward would reduce impacts of weather, energy efficiency programs and economic changes in customer demand. In addition, DPL's and DP&L'sAES Ohio's financial results are likely to be driven by other factors including, but not limited to:

regulatory outcomes;
the passage of new legislation, implementation of regulations or other changes in regulation; and
the timely recovery of transmission and distribution expenditures.

COVID-19 Pandemic

In December 2019, a novel strain of coronavirus (COVID-19) was reported to have surfaced in Wuhan, China.The COVID-19 has since spread to over 180 countries, including every state in the United States. On March 11, 2020 the World Health Organization declared COVID-19 a pandemic and on March 13, 2020 the United States declared a national emergency with respect to COVID-19. On March 12, 2020, the PUCO issued an emergency order prohibiting electric utilities, including us, from discontinuing electric utility service to customers. This prohibition is currently scheduled to end for DP&L on September 1, 2020, pending approval by the PUCO.

The outbreak of COVID-19 has severely impacted global economic activity, including electricity and energy consumption, and caused significant volatility and negative pressure in financial marketsmarkets. Responses to the COVID-19 pandemic by the State of Ohio and reduced the demand for energyits residents and businesses, in our service territory. The global impact of the outbreak has been rapidly evolving and many countries,particular, continue to evolve, including the United States, have reacted by instituting quarantines, mandatingwith respect to business and school closures and restricting travel.limitations and other social distancing measures and the effectiveness and timing of vaccine availability and distribution efforts.

Social distancing measures designed to slow the spread of the virus, such as business closures and operations limitations, impact energy demand within our service industry. In addition to reduced revenues and lower margins resulting from decreased energythe impacts to demand within our service territory, we also have incurred and expect to continue to incur expenses relating to COVID-19, and such expenses may include those that relate to events outside of our control. We experienced impacts from the pandemic in 2020 and into 2021 and expect to continue to experience impacts for the remainder of 2020,2021, and any such impacts during the third quarterthat time or in other future periods could have a material and adverse effecteffects on our results of operations, financial condition and cash flows. The following discussion highlights our assessment of the impacts of the COVID-19 pandemic on our current financial and operating status, and our financial and operational outlook based on information known as of this filing. Also see Part II, "Item 1A-Risk Factors of this1A. Risk Factors" to our Form 10-Q.10-K.

Business Continuity - AsDuring the COVID-19 pandemic, progresses, we are taking a variety of measures to ensure our ability to generate, transmit, distribute and sell electric energy, to ensure the health and safety of our employees, contractors, customers and communities and to provide essential services to the communities in which we operate. We continue to respond to this global crisis through comprehensive measures to protect our employees and others while fulfilling our vital role in providing our customers with electric energy. While there have been stay-at-home restrictions in place in Ohio, our operations are considered essential and have not been significantly disrupted. Stay-at-home restrictions have been lifted in our service territory, and non-essential employees are beginning to return to work at our locations in stages. Mostmost of our management and administrative personnel are able to work remotely, and we have not experienced significant issues affecting our operations or ability to maintain effective internal controls and produce reliable financial information.

Demand - TheAs the economic impact of the COVID-19 pandemic started to materialize in Ohio in the second half of March 2020 and more so incontinued for the second quarterduration of 2020. For the three2020 and six months ended June 30, 2020,into 2021, the COVID-19 pandemic primarily impacted our retail sales demand. For commercial and industrial customers,demand, including for the quarter ended March 31, 2021, as shown by the changes in weather-normalized volumes of kWh sold decreased by 11.0% and 19.9%, respectively, for the three months ended June 30, 2020 compared to the same period in the prior year. For residential customers, weather-normalized volumes of kWh sold increased by 8.5% for the three months ended June 30, 2020 compared to the same period in the prior year. See Note 12 – Revenue of Notes to DPL's Condensed Consolidated Financial Statements and Note 11 – Revenue of Notes to DP&L's Condensed Financial Statements for a disaggregation of retail revenues by customer class. The declines for commercial and industrial customers were more severe in April and May, and partially recovered in Juneclass as stay-at-home orders were lifted, while the increase for residential stayed consistent. While we cannot predict the length and magnitude of the pandemic or how it could ultimately impact global or local economic conditions, continuous and/or further declines in future demand would adversely impact our financial results for 2020 and beyond.follows:

Government and Other(3.9)%

Liquidity - We anticipate havingcontinuing to have sufficient liquidity to make all required payments, including payments for salaries and wages owed to our employees, during the COVID-19 pandemic. We doalso continue to not foresee a significant impact to our access to capital or our liquidity position as a result of the COVID-19 pandemic. On June 19, 2020 DPL closed a $415.0 million issuance of senior unsecured notes, and the proceeds from this issuance together with cash on hand were used to redeem in-full the remaining balance of $380.0 million of DPL's 7.25% senior unsecured notes. These bonds were redeemed at par plus accrued interest and a make-whole premium of $30.8 million on July 20, 2020. Additionally, on July 31, 2020 DP&L issued $140.0 million of taxable First Mortgage Bonds and used the proceeds to purchase at par value the $140.0 million of outstanding tax-exempt Ohio Air Quality Development Authority Collateralized Pollution Control Revenue Refunding Bonds that had been issued in 2015.

Credit Exposures - We continue to monitor and manage our credit exposures in a prudent manner. During the three monthsyear ended June 30,December 31, 2020, we experienced credit-related impacts from utility customers due to the prohibition of electric utilities, including us, from discontinuing electric utility service to customers through September 1, 2020 and due to the economic impacts of the COVID-19 pandemic. This has resultedpandemic, which began to improve in an increase in past due customer receivable balances,2021. See Note 2 – Supplemental Financial Information of Notes to DPL's Condensed Consolidated Financial Statements and Note 2 – Supplemental Financial Information or Notes to AES Ohio's Condensed Financial Statements for further discussion of our allowance for credit losses has increased $2.3 million for both DPL and DP&L during the second quarter of 2020. We expect significant economic disruptionslosses. If these credit-related impacts from the COVID-19 pandemic potentially for the remainder of 2020 and beyond. If these disruptions occur,continue into 2021 or beyond, further deterioration in our credit exposures and customer collections couldmay result. However, as discussed in Note 3 – Regulatory Matters of Notes to DPL's Condensed Consolidated Financial Statements and Note 3 – Regulatory Matters of Notes to DP&L'sAES Ohio's Condensed Financial Statements in Item 8. - Financial Statements and Supplementary Data of our Form 10-K, DP&L’sAES Ohio’s uncollectible expense is deferred for future collection. The prohibition from discontinuing electric utility service is currently scheduled to end for DP&L on September 1, 2020, pending approval by the PUCO.

Supply Chain - Our supply chain management has remained robust during this challenging time and we continue to closely manage and monitor developments.

Capital Projects - During the COVID-19 pandemic, our construction projects are proceeding without material delays. For further discussion of our capital requirements, see Part I, Item 2 Management’sManagement's Discussion and Analysis of Financial Condition and Results of Operations Capital Resources and Liquidity of this Form 10-Q.

CARES Act - The Coronavirus Aid, Relief, and Economic Security (CARES)("CARES") Act was passed by the U.S. Congress and signed into law on March 27, 2020. While we currently expect a limited impact from this legislation on our business, certain elements, primarilywe have deferred the deferralpayment of federal payroll taxes may provide some cash benefits in accordance with the near term.

Income Taxes - The demands placed onprovisions of this act. At March 31, 2021, the U.S. Government to respond to the pandemic may cause delays to the expected issuance of regulations pursuant to the TCJA enacted in 2017. Our interpretation of the TCJA may change as the U.S. Treasury and the Internal Revenue Service issue additional guidance. Such changes may be material.total deferral was approximately $2.1 million.

Regulatory Environment
DPL’s, DP&L’sAES Ohio’s and our other subsidiaries’ facilities and operations are subject to a wide range of regulations and laws by federal, state and local authorities. As well as imposing continuing compliance obligations, these laws and regulations authorize the imposition of substantial penalties for noncompliance, including fines, injunctive relief and other sanctions. In the normal course of business, we have investigatory and remedial activities underway at these facilities and operations in an effort to comply, or to determine compliance, with such regulations. We record liabilities for losses that are probable and can be reasonably estimated. In addition to matters discussed or updated herein, our 20192020 Form 10-K and Form 10-Q previously filed with the SEC during 2020 describe2021 describes other regulatory matters which have not materially changed since those filings.that filing.

Ohio House Bill 6 - In late July 2020, Senate Bill 346 and House Bill 738 were introduced in the Ohio General Assembly seeking to repeal– Legislation was passed, Ohio House Bill 6.128, that repeals Ohio House Bill 6 among other things, doesprovisions related to a nuclear fund and decoupling, effective June 30, 2021. Other provisions from Ohio House Bill 6 currently remain in place, which include the following: beginning January 1, 2020, permitted Ohio utilities, such as DP&LAES Ohio, tomay defer, recover or credit the net proceeds from selling energy and capacity received as part of DP&L'stheir interest in OVEC and itstheir OVEC-related costs through a statewide non-bypassable recovery mechanism for recovery of prudently incurred OVEC costs through 2030; eliminates the annual energy efficiency targets for Ohio utilities after 2020; and allows Ohio utilities to construct customer-sited

renewable generation for mercantile customers or groups of mercantile customers, the costs of which may only be recovered from those customers. If these provisions from Ohio House Bill 6 isare repealed without a replacement with comparable provisions, it could have a material adverse effect on our results of operations, financial condition and cash flows.

Reference Rate Reform
As discussed in Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations, of our Form 10-K, in July 2017, the U.K.UK Financial Conduct Authority announced that it intends to phase out LIBOR by the end of 2021. In the U.S., the Alternative Reference Rate Committee at the Federal Reserve identified the Secured Overnight Financing Rate (SOFR)("SOFR") as its preferred alternative rate for LIBOR; alternative reference rates in other key markets are under development. On November 30, 2020, the ICE Benchmark Association ("IBA") announced it had begun consultation on its intention to cease publication of two specific LIBOR rates by December 31, 2021, while extending the timeline for the overnight, one-month, three-month, six-month, and 12-month USD LIBOR rates through June 30, 2023. On March 5, 2021, IBA published a feedback statement for the consultation, announcing its intention to cease the publication of these rates on the specified dates. We maintain financial instruments that use LIBOR as an interest rate benchmark andbenchmark. Although the full impact of the reform remains unknown, we have begun to engage with our counterparties to discuss specific action items to be undertaken in order to prepare for amendments when they become due.

Environmental Matters
In addition to imposing continuing compliance obligations, these laws and regulations authorize the imposition of substantial penalties for noncompliance, including fines, injunctive relief and other sanctions. In the normal course of business, we have investigatory and remedial activities underway at our facilities to comply, or to determine compliance, with such regulations. We record liabilities for loss contingencies related to environmental matters when a loss is probable of occurring and can be reasonably estimated in accordance with the provisions of GAAP. Accordingly, we have immaterial accruals for loss contingencies for environmental matters. We also have several environmental matters for which we have not accrued loss contingencies because the risk of loss is not probable, or a loss cannot be reasonably estimated. We evaluate the potential liability related to environmental matters quarterly and may revise our estimates. Such revisions in the estimates of the potential liabilities could have a material adverse effect on our results of operations, financial condition and cash flows. We refer to the discussion in “Item 1. Business - Environmental Matters” in our 20192020 Form 10-K for a discussion of certain recent developments in environmental laws and regulations.

We have several pending environmental matters associated with our previously-owned stations. Some of these matters could have a material adverse effect on our results of operations, financial condition and cash flows.

As a result of DPL’s retirement and subsequent sale of its Stuart and Killen generating stations, the sale of its ownership interest in the Miami Fort and Zimmer generating stations and the retirement and subsequent sale of Conesville, the following environmental matters, regulations and requirements are now not expected to have a material impact on DPL:
CSAPR and associated updates;
MATS and any associated regulatory or judicial processes;
NAAQS; and
the Affordablepotential Clean Energy Rule.Air Act Section 111(d) regulations for greenhouse gases from existing electric generating units.

Clean Air Act - Cross State Air Pollution Rule
RegulationCSAPR, which became effective in January 2015, addresses the "good neighbor" provision of CCR
Onthe CAA, which prohibits sources within each state from emitting any air pollutant in an amount which will contribute significantly to any other state’s nonattainment, or interference with maintenance of, any NAAQS. The CSAPR is implemented, in part, through a market-based program under which compliance may be achievable through the acquisition and use of emissions allowances created by the USEPA. In October 19, 2015,2016, the USEPA published a final rule to update the CSAPR to address the 2008 ozone NAAQS (“CSAPR Update Rule”). The CSAPR Update Rule found that NOx ozone season emissions in 22 states (including Ohio) affect the ability of downwind states to attain and maintain the 2008 ozone NAAQS, and accordingly, the USEPA rule regulating CCR underissued federal implementation plans that both generally provide updated CSAPR NOx ozone season emission budgets for electric generating units within these states and that implement these budgets through modifications to the Resource Conservation and Recovery Act as nonhazardous solid waste became effective. The rule established nationally applicable minimum criteria forCSAPR NOx ozone season allowance trading program. In December 2018, the disposal of CCR in new and currently operating landfills and surface impoundments, including location restrictions,USEPA determined that the 2016 CSAPR Update Rule fully satisfied 20 states (including Ohio) good neighbor obligations with respect to the 2008 Ozone NAAQS (“CSAPR Close-Out Rule”), obviating the need

design and operating criteria, groundwater monitoring, corrective action and closure requirements and post-closure care. The primary enforcement mechanisms under this regulation would be actions commenced by the states and private lawsuits. On December 16, 2016, President Obama signed into law the Water Infrastructure Improvements for the Nation Act (WIIN Act), which includes provisions to implement the CCR rule through a state permitting program, or if the state chooses not to participate, a possible federal permit program. The USEPA has indicated that they will implement a phased approach to amending the CCR Rule which is in process. On February 20, 2020, the US EPA published a proposed rule to establish a federal CCR permit program that would operate in states without approved CCR permit programs. On July 29, 2020, the USEPA released a pre-publication version of final amendments to the CCR rule titled “A Holistic Approach to Closure Part A: Deadline to Initiate Closure”. It is too early to determine whether the CCR rule or any revisions to or reconsideration of the rule may have a material impact on our business, financial condition or results of operations.

Litigation Involving Previously Co-Owned Stations
As a result of a 2008 consent decree entered into with the Sierra Club and approved by the U.S. District Court
for the Southern District of Ohio, DPL USEPA to promulgate Federal Implementation Plans (FIPs) in these states. In October 2019, the D.C. Circuit vacated and remanded the other previous owners of the Stuart generating station were subject to
certain specified emission targets related to NOX, SO2 and particulate matter. The consent decree also includes
commitments for energy efficiency and renewable energy activities. An amendment to the consent decree was
entered into and approved in 2010 to clarify how emissions would be computed during startups. Given that all
of the commitments have been met and with the retirement of the Stuart generating station, DPL and the other previous owners submitted a request for termination of the consent decree to the U.S. District Court.CSAPR Close-Out Rule. On July 14, 2020, the U.S. District Court granted the request and terminated the Consent Decree.

Clean Water Act - Regulation of Water Discharge
DP&L and other utilities at times apply the Nationwide Permit 12 (NWP 12) issued by the U.S. Army Corps of Engineers (Corps) in completing transmission and distribution projects that may involve waters of the U.S. NWP 12 is the nationwide permit for Utility Line Activities, specifically those required for construction and maintenance, provided the activity does not result in the loss of greater than 1/2-acre of waters of the U.S. for each single and complete project.

On April 15, 2020, in a proceeding involving the construction of the Keystone XL pipeline, the U.S. District Court for the District of Montana (Montana District Court) vacated NWP 12 and enjoined its application. On April 27, 2020, the Corps moved for the Montana District Court to stay pending appeal those portions of the April 15, 2020 order that vacate NWP 12 and enjoin its application. In the alternative, the Corps asked the Montana District Court to stay its vacatur and injunction as they relate to anything other than the Keystone XL pipeline. On May 11, 2020, following a request from the Corps, the Montana District Court amended its order to vacate NWP 12 only for oil and gas pipeline construction projects, allowing electric utility T&D projects to continue. On May 13, the Corps appealed the Montana District Court decision with the Ninth Circuit Court and requested a stay. On May 28, 2020, the NinthD.C. Circuit deniedordered the USEPA to issue FIPs addressing seven states’ (including Ohio) outstanding 2008 NAAQS “good neighbor” obligations by March 15, 2021. On April 30, 2021, the USEPA published a motionfinal rule to stay. On June 16,address the 2020 D.C. Circuit decision. The USEPA is issuing new or amended federal implementation plans for 12 states, including Ohio, with revised CSAPR NOx ozone season emission budgets for electric generating units within these states via a new CSAPR NOx Ozone Season Group 3 Trading Program.

County of Maui case related to whether a Clean Water Act permit is required when pollutants originate from a point source but are conveyed to navigable waters through a nonpoint source such as groundwater. The U.S. Supreme Court held that discharges to groundwater require a permit if the addition of the pollutants through groundwater is the functional equivalentof a direct discharge from the point source into navigable waters. It is too early to determine whether this decision may have a material impact on our business, financial condition or results of operations.Operations.

On July 31, 2020 DP&L issued $140.0 million of taxable First Mortgage Bonds and on August 3, 2020 used the proceeds to purchase at par value the $140.0 million of outstanding tax-exempt Ohio Air Quality Development Authority Collateralized Pollution Control Revenue Refunding Bonds that had been issued in 2015. The new taxable First Mortgage Bonds carry an interest rate of 3.20% and mature on July 31, 2040. As a result of this refinancing, the $140.0 million tax-exempt First Mortgage Bonds are presented as long-term debt as of June 30, 2020.

From time to time, we may elect to repurchase our outstanding debt through cash purchases, privately negotiated transactions or otherwise when management believes such repurchases are favorable to make. The amounts involved in any such repurchases may be material.

We depend on timely and continued access to capital markets to manage our liquidity needs. The inability to raise capital on favorable terms, to refinance existing indebtedness or to fund operations and other commitments during times of political or economic uncertainty could have a material adverse effect on our results of operations, financial condition and cash flows. In addition, changes in the timing of tariff increases or delays in regulatory determinations could affect the cash flows and results of operations of our businesses.

Our discussion of DPL’s financial condition, liquidity and capital requirements include the results of its principal subsidiary DP&LAES Ohio.

LIQUIDITY
We expect our existing sources of liquidity to remain sufficient to meet our anticipated operating needs. Our business is capital intensive, requiring significant resources to fund operating expenses, construction expenditures, scheduled debt maturities and carrying costs, taxes and dividend payments. For 20202021 and subsequent years, we expect to satisfy these requirements with cash from operations, funds from debt financing and/or equity capital contributions as our internal liquidity needs and market conditions warrant. We also expect that the borrowing capacity under bank credit facilities will continue to be available to manage working capital requirements during those periods. During the six months ended June 30, 2020, DPL received $150.0 million in a cash contribution from AES, which DPL then used to make a $150.0 million capital contribution to DP&L. The contribution at DPL represented an equity capital contribution of $98.0 million and a payment of $52.0 million against its tax receivable. The proceeds from the capital contribution at DP&L will primarily be used for funding needs to support DP&L's capital expenditure program, mainly new investments in and upgrades to DP&L’s transmission and distribution system.

At June 30, 2020,March 31, 2021, DP&LAES Ohio and DPL have access to the following revolving credit facilities:

If the rating agencies were to reduce our debt or credit ratings, our borrowing costs may increase, our potential pool of investors and funding resources may be reduced, and we may be required to post additional collateral under selected contracts. These events could have an adverse effect on our results of operations, financial condition and cash flows. In addition, any such reduction in our debt or credit ratings may adversely affect the trading price of our outstanding debt securities.

MARKET RISK

We are subject to certain market risks including, but not limited to, changes in commodity prices for electricity and fluctuations in interest rates. Our Risk Management Committee (RMC), comprised of members of senior management, is responsible for establishing risk management policies and the monitoring and reporting of risk

exposures. The RMC meets on a regular basis with the objective of identifying, assessing and quantifying material risk issues and developing strategies to manage these risks.

The disclosures presented in this section are based upon a number of assumptions; actual effects may differ. The safe harbor provided in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 shall apply to the disclosures contained in this section. For further information regarding market risk, see Item 1A.—Risk Factors and Item 7A - Quantitative and Qualitative Disclosures about Market Risk of our Form 10-K. Our businesses may incur substantial costs and liabilities and be exposed to price volatility as a result of risks associated with the electricity markets, which could have a material adverse effect on our results of operations,

financial condition and cash flows. In addition, we may not be adequately hedged against our exposure to changes in interest rates.

Interest Rate Risk
Because of our normal investing and borrowing activities, our financial results are exposed to fluctuations in interest rates which we manage through our regular financing activities. We maintain both cash on deposit and investments in cash equivalents that may be affected by adverse interest rate fluctuations. DPL has fixed-rate long-term debt. After the refinancing of the tax-exempt first mortgage bonds, DP&L only has fixed-rate long-term debt.

As of June 30, 2020, we have two interest rate swaps to hedge the variable interest on our $140.0 million variable interest rate tax-exempt First Mortgage Bonds. The interest rate swaps have a combined notional amount of $140.0 million and settle monthly based on a one-month LIBOR. The

Long-term debt maturities and repayments occurring in the next twelve months are discussed under "CAPITAL RESOURCES AND LIQUIDITY".

Critical Accounting Estimates

DPL’s Condensed Consolidated Financial Statements and DP&L’sAES Ohio’s Condensed Financial Statements are prepared in accordance with GAAP. In connection with the preparation of these financial statements, our management is required to make assumptions, estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and the related disclosure of contingent liabilities. These assumptions, estimates and judgments are based on our historical experience and assumptions that we believe to be reasonable at the time. However, because future events and their effects cannot be determined with certainty, the determination of estimates requires the exercise of judgment. Our critical accounting estimates are those which require assumptions to be made about matters that are highly uncertain.

Different estimates could have a material effect on our financial results. Judgments and uncertainties affecting the application of these policies and estimates may result in materially different amounts being reported under different conditions or circumstances. Historically, however, recorded estimates have not differed materially from actual results. Significant items subject to such judgments include: the carrying value of property, plant and equipment; unbilled revenues; the valuation of derivative instruments; the valuation of insurance and claims liabilities; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; liabilities recorded for income tax exposures; litigation; contingencies; the valuation of AROs; assets and liabilities related to employee benefits and intangible assets. Refer to our Form 10-K for the year ended December 31, 20192020 for a complete listing of our critical accounting policies and estimates. We have reviewed and determined that these remain as critical accounting policies as of and for the sixthree months ended June 30, 2020.March 31, 2021.

Item 4 – Controls and Procedures

Disclosure Controls and Procedures
DPL and DP&LAES Ohio, under the supervision and with the participation of its management, including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), evaluated the effectiveness of our “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of June 30,
67

Table of Contents
2020,March 31, 2021, to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and include controls and procedures designed to ensure that information required to be disclosed by us in such reports is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosures.

Changes in Internal Controls over Financial Reporting — There were no changes that occurred during the fiscal quarter covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite the fact that most of our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the COVID-19 situation on our internal controls to minimize the impact on their design and operating effectiveness.

Part II – Other Information

Item 1 – Legal Proceedings

In the normal course of business, we are subject to various lawsuits, actions, claims, and other proceedings. We are also, from time to time, involved in other reviews, investigations and proceedings by governmental and regulatory agencies regarding our business, certain of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. We have accrued in our Financial Statements for litigation and claims where it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We believe the amounts provided in our Financial Statements, as prescribed by GAAP, for these matters are adequate considering the probable and estimable contingencies. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various legal proceedings, claims and other matters (including those matters noted below), and to comply with applicable laws and regulations will not exceed the amounts reflected in our Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided for in our Financial Statements, cannot be reasonably determined, but could be material.

Our Form 10-K for the fiscal year ended December 31, 2019 and Form 10-Q for the quarter ended March 31, 2020 and the Notes to DPL’s Consolidated Financial Statements and DP&L’sAES Ohio’s Financial Statements included therein contain descriptions of certain legal proceedings in which we are or were involved. The information in or incorporated by reference into this Item 1 to Part II is limited to certain recent developments concerning our legal proceedings and new legal proceedings, since the filing of such FormsForm 10-K, and 10-Q, and should be read in conjunction with such Forms 10-K and 10-Q.Form 10-K.

Item 1A – Risk Factors

A listing of the risk factors that we consider to be the most significant to a decision to invest in our securities is provided in our Form 10-K as supplemented in our Form 10-Q for the three months ended March 32, 2020. Except as described below, there hasThere have been no material change in ourchanges to the risk factors as previously disclosed in our Form 10-K and 2020 first quarter Form 10-Q. If any of the events described in our risk factors occur, it could have a material adverse effect on our results of operations, financial condition and cash flows.

The risks and uncertainties described in our risk factors are not the only ones we face. In addition, new risks may emerge at any time, and we cannot predict those risks or estimate the extent to which they may affect our business or financial performance. Our risk factors should be read in conjunction with the other detailed information concerning DPL and DP&L set forth in the Notes to DPL’s and DP&L’s Financial Statements found in Part I, Item 1, and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections included in our filings.

As part of the filing of this Quarterly Report Form on Form 10-Q, we are further revising, clarifying and
68

Table of Contents
supplementing our risk factors, including those contained in our Form 10-K. The risk factor below amends and supersedes the risk factor that we filed in connection with the 2020 first quarter Form 10-Q and should be considered together with the other risk factors described in our Form 10-K:

The current outbreak of the novel coronavirus, or COVID-19, has adversely affected, and it or the future outbreak of any other highly infectious or contagious diseases could materially and adversely affect, our generation facilities, transmission and distribution systems, results of operations, financial condition and cash flows. Further, the spread of the COVID-19 outbreak has caused severe disruptions in the U.S. and global economy and financial markets and could potentially create widespread business continuity issues of an as yet unknown magnitude and duration.

In December 2019, a novel strain of coronavirus (COVID-19) was reported to have surfaced in Wuhan, China. COVID-19 has since spread to over 180 countries, including every state in the United States. On March 11, 2020 the World Health Organization declared COVID-19 a pandemic, and on March 13, 2020 the United States declared a national emergency with respect to COVID-19. On March 12, 2020, the PUCO issued an emergency order prohibiting electric utilities, including us, from discontinuing electric utility service to customers, which prohibition is currently scheduled to end September 1, 2020 for DP&L pending PUCO approval.

The outbreak of COVID-19 has severely impacted global economic activity, caused significant volatility and negative pressure in financial markets and reduced the demand for energy in our service territory. In addition to reduced revenues and lower margins resulting from decreased energy demand within our service territory, we also will incur expenses relating to COVID-19, and such expenses may include those that relate to events outside of our control. The global impact of the outbreak has been rapidly evolving and many countries, including the United States, have reacted by instituting quarantines, mandating business and school closures and restricting travel. Many experts predict that the outbreak will trigger a period of global economic slowdown or a global recession. COVID-19 or another pandemic could have material and adverse effects on our results of operations, financial condition and cash flows due to, among other factors:

further decline in customer demand as a result of general decline in business activity;
further destabilization of the markets and decline in business activity negatively impacting our customer growth or the number of customers in our service territory as well as our customers’ ability to pay for our services when due (or at all);
delay or inability in obtaining regulatory actions and outcomes that could be material to our business, including for recovery of COVID-19 related expenses and losses and the review and approval of our applications, rates and charges by the PUCO;
difficulty accessing the capital and credit markets on favorable terms, or at all, and a severe disruption and instability in the global financial markets, or deteriorations in credit and financing conditions which could affect our access to capital necessary to fund business operations or address maturing liabilities on a timely basis;
negative impacts on the health of our essential personnel, especially if a significant number of them are affected, and on our operations as a result of implementing stay-at-home, quarantine and other social distancing measures;
a deterioration in our ability to ensure business continuity during a disruption, including increased cybersecurity attacks related to the work-from-home environment;
delays or inability to access, transport and deliver materials to our facilities due to restrictions on business operations or other factors affecting us and our third-party suppliers;
delays or inability to access equipment or the availability of personnel to perform planned and unplanned maintenance, which can, in turn, lead to disruption in operations;
delays or inability in achieving our financial goals, growth strategy and digital transformation; and
delays in the implementation of expected rules and regulations, including with respect to the TCJA.

We will continue to review and modify our plans as conditions change. Despite our efforts to manage and remedy these impacts to the Company, their ultimate impact also depends on factors beyond our knowledge or control, including the duration and severity of this outbreak as well as third-party actions taken to contain its spread and mitigate its public health effects.

The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19. Nevertheless, COVID-19 presents material uncertainty which could materially and adversely affect our transmission and distribution systems, results of operations, financial condition and cash flows.

To the extent COVID-19 adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this ‘‘Risk Factors’’ section, such as those relating to our level of indebtedness, our need to generate sufficient cash flows to service our indebtedness and our ability to comply with the covenants contained in the agreements that govern our indebtedness.
