Safety
As part of AES, safety is one of our core values. Conducting safe operations at our facilities, so that each person can return home safely, is the cornerstone of our daily activities and decisions. Safety efforts are led globally by the AES Chief Operating Officer and supported by safety committees that operate at the local site level. Hazards in the workplace are actively identified and management tracks incidents so remedial actions can be taken to improve workplace safety.

We work with the AES Safety Management System (“SMS”), a Global Safety Standard that applies to all AES employees and employees of AES subsidiaries, as well as contractors working in AES facilities and construction projects. The SMS requires continuous safety performance monitoring, risk assessment and performance of periodic integrated environmental, health and safety audits. The SMS provides a consistent framework for all AES operational businesses and construction projects to set expectations for risk identification and reduction, measure performance and drive continuous improvements. The SMS standard is consistent with the OHSA 18001/ISO 45001 standard. Our safety performance is also measured by both leading and lagging metrics. Our leading safety metrics track safety observations, safety meeting engagement and the reporting of non-injury significant injury potential incidents. Our lagging safety metrics track lost workday cases, severity rate, and recordable incidents.

SERVICE COMPANY


The Service Company provides services including operations, accounting, legal, human resources, information technology and other corporate services of a similar nature on behalf of companies that are part of the U.S. SBU, including, among other companies, DPL and DP&LAES Ohio. The Service Company allocates the costs for these services based on cost drivers designed to result in fair and equitable allocations. This includes ensuring that the regulated businessesutilities served, including DP&LAES Ohio, are not subsidizing costs incurred for the benefit of other businesses. See Note 1211 – Related Party Transactions of Notes to DPL's Consolidated Financial Statements and Note 1211 – Related Party Transactions of Notes to DP&L'sAES Ohio's Financial Statements.


SEASONALITY


The power delivery business is seasonal, and weather patterns have a material effect on energy demand. In the region we serve, demand for electricity is generally greater in the summer months associated with cooling and in the winter months associated with heating compared to other times of the year. DP&L'sAES Ohio's sales typically reflect the seasonal weather patterns but can also be impacted by economic activity, COVID-19, and the growthnumber of retail customers we have. The impacts of weather, energy efficiency initiatives, however, afterprograms and economic changes in customer demand were almost entirely eliminated in 2019 by AES Ohio’s Decoupling Rider, which was in place from January 1, 2019 until December 18, 2019. AES Ohio has requested authority from the approval ofPUCO to create a regulatory asset for the distribution rate order in 2018, our distributionongoing revenues that would have been decoupled from weathercharged in the Decoupling Rider going back to December 18, 2019. A hearing on this request was held in May 2021 and energy efficiency variations. Becauseis pending a decision by the PUCO. See Note 2 – Regulatory Matters of the impactNotes to DPL's Consolidated Financial Statements and Note 2 – Regulatory Matters of the new decoupling rider (effective January 1, 2019) and because DPL's generation has greatly decreased in recent years dueNotes to plant sales and closures, we expect that weather and other factors influencing demand will have minimal impact on our net operating results going forward.AES Ohio's Financial Statements.


Storm activity can also have an adverse effect on our operating performance. Severe storms often damage transmission and distribution equipment, thereby causing power outages, which reduce revenues and increase repair costs. Partially mitigating this impact is DP&L’sAES Ohio’s ability to timely recover certain O&M repair costs related to severe storms.


MARKET STRUCTURE


Retail rate regulation
DP&L's deliveryAES Ohio's distribution service to all retail customers as well as the provisions of its SSO service are regulated by the PUCO. In addition, certain costs are considered to be non-bypassable and are therefore assessed to all DP&LAES Ohio retail customers, under the regulatory authority of the PUCO, regardless of the customer’s retail electric supplier. DP&L'sAES Ohio's transmission rates are subject to regulation by the FERC under the Federal Power Act.


Ohio law establishes the process for determining SSO and non-bypassable rates charged by public utilities. Regulation of retail rates encompasses the timing of applications, the effective date of rate changes, the cost basis upon which the rates are set and other service-related matters. Ohio law also established the Office of the OCC,Ohio Consumers' Counsel, which has the authority to represent residential consumers in state and federal judicial and administrative rate proceedings.


Ohio legislation extends the jurisdiction of the PUCO to the records and accounts of certain public utility holding company systems, including DPL. The legislation extends the PUCO's supervisory powers to a holding company system's general condition and capitalization, among other matters, to the extent that such matters relate to the costs associated with the provision of public utility service. Based on existing PUCO and FERC authorization, regulatory assets and liabilities are recorded on the balance sheets of both DPL and DP&L. AES Ohio. See Note 32 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements and Note 32 – Regulatory Matters of Notes to DP&L'sAES Ohio's Financial Statements.

The six-year 2017 ESP establishes DP&L's1 established AES Ohio's framework for providing retail service on a going-forward basis including rate structures, non-bypassable charges and other specific rate recovery true-up rider mechanisms. For more information regarding AES Ohio's ESP, see Note 2 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements and Note 2 – Regulatory Matters of Notes to AES Ohio's Financial Statements.


On September 26, 2018, the PUCO issued the DRO establishing new base distribution rates for DP&LAES Ohio, which became effective October 1, 2018. The DRO approved, without modification, a stipulation and recommendation previously filed by DP&LAES Ohio, along with various intervening parties and the PUCO staff. The DRO established a revenue requirement of $248.0 million for DP&L'sAES Ohio's electric service base distribution rates which reflects an increase to distribution revenues of approximately $29.8 million per year. In addition to the increase in base distribution rates, among other matters, therates. The DRO also providesprovided for a return on equity of 9.999% and a cost of long-term debt of 4.8%.


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. For more information, regarding DP&L's ESP and DRO, see Note 32 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements and Note 32 – Regulatory Matters of Notes to DP&L'sAES Ohio's Financial Statements.


In December 2018, DP&LAES Ohio filed a Distribution Modernizationits Smart Grid Plan (“DMP”) with the PUCO proposing to invest $576.0 million in capital projects over the next 10 years. There are eight principal components of DP&L’s DMP: Smart Grid Plan: 1) Smart Meters, 2) Self-Healing Grid, 3) Customer Engagement, 4) Enhancing Sustainability and Embracing Innovation. 5) Telecommunications, 6) Physical and Cyber Security, 7) Governance and Analytics and 8) Grid Modernization R&D.


These initiatives will also allow DP&LOn October 23, 2020, AES Ohio 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, be ready to leverage and integrate Distributed Energy Resources into its grid, including demonstrations of community solar, energy storage, microgrids, as well as Electric Vehicle charging infrastructure. If approved, DP&L will implement a comprehensive grid modernization project that will deliver benefits to customers, society as a whole and to the Company.

On January 22, 2019, DP&L filed a request withamong other matters, AES Ohio's applications pending at the PUCO for a two-year extension(i) approval of AES Ohio's plan to modernize its DMR through October 2022,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 satisfies the SEET and the more favorable in the proposed amountaggregate (MFA) regulatory test. A hearing was held in January 2021 for consideration of $199.0 millionthis settlement and on June 16, 2021, the PUCO issued their opinion and order accepting the stipulation as filed. Several applications for eachrehearing of the two additional years. The request was made pursuantPUCO's orders relating to the PUCO’s October 20, 2017 ESPcomprehensive settlement were filed and denied on December 1, 2021. The OCC appealed this PUCO Order to the Ohio Supreme Court on December 6, 2021; this appeal remains pending. Consistent with AES' earlier statement of intent, with the PUCO's issuance of their opinion and order, which approved the DMRduring 2021 DPL received $150.0 million from AES and, had the option for DP&Lin turn, DPL made a capital contribution of $150.0 million to file for a two-year extension. The extension request was set at a level expectedAES Ohio to reduce debt obligations at both DP&L and DPL andenable AES Ohio to position DP&L seek to make capital expenditures to maintainimprove its infrastructure and modernize its electric grid. To that end, DP&L’s DMP investments are contingent upon the PUCO approving the two-year extensiongrid while maintaining liquidity. For more information, see Note 2 – Regulatory Matters of its DMR.Notes to DPL's Consolidated Financial Statements and Note 2 – Regulatory Matters of Notes to AES Ohio's Financial Statements.


Ohio law and the PUCO rules contain targets relating to renewable energy peak demand reduction and energy efficiency standards. If any targets are not met, compliance penalties will apply unless the PUCO makes certain findings that would excuse performance. DP&LAES Ohio is currently in full compliance with energy efficiency, peak demand reduction and renewable energy targets. DP&L is required to file an energy efficiency portfolio plan to demonstrate how it plans to meet the standards. On June 15, 2017, DP&L filed an energy efficiency portfolio plan for programs in years 2018 through 2020, which was settled and approved by the PUCO on December 20, 2017. DP&LAES Ohio recovers the costs of its compliance with Ohio energy efficiency and renewable energy standards through separate ridersits Standard Offer Rate Tariff, which areis reviewed and audited by the PUCO.


The costs associated with providing high voltage transmission service and wholesale electric sales and ancillary services are subject to FERC jurisdiction. While DPL has market-basedAES Ohio implemented a formula-based rate authority for wholesale electric sales, DPL would be requiredits transmission service, effective May 3, 2020. For more information, see Note 2 – Regulatory Matters of Notes to file an application at FERC under section 101DPL's Consolidated Financial Statements and Note 2 – Regulatory Matters of Title 18 of the Code of Federal RegulationsNotes to change any of its cost-based transmission or ancillary service rates.AES Ohio's Financial Statements.


As a member of PJM, DP&LAES Ohio receives revenues from the RTO related to DP&L’sAES Ohio’s transmission assets and incurs costs associated with its load obligations for retail customers. Ohio law includes a provision that would allow Ohio electric utilities to seek and obtain a reconcilable rider to recover RTO-related costs and credits. DP&LAES Ohio continues to recover non-market-based transmission and ancillary costs through its transmission rider.nonbypassable Transmission Cost Recovery Rider.


DP&LIn response to filings made by AES Ohio and AES Ohio Generation, filed an application before the FERC to adjust their rates with respect to reactive power provided to PJM from their generation units. On March 3, 2017, DP&L, AES Ohio Generation, and certain intervening parties filed an Offer of Settlement that was approved by the FERC on May 16, 2017. The changes from current2017 reactive power rates for the generation facilities that were not material. Additionally,owned at that time. In the same order, FERC has referred to the FERC’s Office of Enforcement for investigation, an issue regardingAES Ohio’s reactive power charges under the previously effective rates in light of changes in DP&L’sAES Ohio’s generation portfolio.

Several other utilities within PJM are also being investigated by FERC’s Office of Enforcement with respect to the same issue of changes in the generation portfolio that occurred in between rate proceedings. In connection with transactions and other matters discussed above, there have been subsequent reactive power filings made, including filings to reflect: the transfer

DP&L is subject to a SEET threshold and is required to apply general rules for calculating earnings and comparing them to a comparable group to determine whether there were significantly excessive earnings during a given calendar year. In future years, the SEET could have a material effect on results of operations, financial condition and cash flows. See Note 3 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements and Note 3 – Regulatory Matters of Notes to DP&L's Financial Statements.

Ohio Competition
Since January 2001, DP&L’sAES Ohio’s electric customers have been permitted to choose their retail electric generation supplier. DP&LAES Ohio continues to have the exclusive right to provide delivery service in its state-certified territory and the obligation to procure and provide electricity to SSO customers that do not choose an alternative supplier. The PUCO maintains jurisdiction over DP&L’sAES Ohio’s delivery of electricity, SSO and other retail electric services.


As part of Ohio’s electric deregulation law, all of the state’s investor-owned utilities were required to join an RTO. DP&LAES Ohio is a member of the PJM RTO. The role of the RTO is to administer a competitive wholesale market for electricity and ensure reliability of the transmission grid. PJM ensures the reliability of the high-voltage electric power system serving more than 5065 million people in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia. PJM coordinates and directs the operation of the region’s transmission grid, administers the world’s largest competitive wholesale electricity market and plans regional transmission expansion improvements to maintain grid reliability and relieve congestion.

Like other electric utilities and energy marketers, AES Ohio Generation may sell or purchase electric products in the wholesale market. AES Ohio Generation competes with other generators, power marketers, privately and municipally-owned electric utilities and rural electric cooperatives when selling electricity. The ability of AES Ohio Generation to sell this electricity will depend not only on the performance of its generating unit, but also on how AES Ohio Generation’s prices, terms and conditions compare to those of other suppliers.


ENVIRONMENTAL MATTERS


DPL’s and DP&L'sAES Ohio's current and former facilities and operations are and/or were subject to a wide range of federal, state and local environmental laws, rules and regulations. The environmental issues that may affect us include the following. However,are discussed below; however, as describeddiscussed further below, as a result ofDPL’s retirement of its Stuart and Killen generating stations, the sale of its ownership interest in the Miami Fort and Zimmer generating stations, the planned 2020 retirement of Conesville and our exiting of our generation business, certain of these environmental regulations and lawsrequirements are now notno longer expected to have a material impact on DPL with respect to these generating stations. and AES Ohio.

In addition to imposing continuing compliance obligations, theseenvironmental laws, rules 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 laws, rules and 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 a number of 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 or cash flows.

We have several pending environmental matters associated with our previously-owned and operated coal-fired generation units. We do not expect these matters to have a material adverse impact on our results of operations, financial condition or cash flows.

Biden Administration Actions Affecting Environmental Regulations
On January 20, 2021, President Biden issued an Executive Order (the "EO") titled “Protecting Public Health and the Environment and Restoring Science to Executive Orders fromTackle the Climate Crisis” directing agencies to, among other tasks, review regulations issued under the previous administration to determine whether they should be suspended, revoked, or revised. As provided for by the EO, the USEPA submitted a letter to the U.S. President, the USEPA is currently evaluating various existing regulationsDepartment of Justice seeking to be considered for repeal, replacement,obtain abeyances or modification. We cannot predict at this time the likely outcomestays of the USEPA’sproceedings in pending litigation that seeks review of theseregulations promulgated during the Trump Administration. The Biden Administration also issued a Memorandum titled “Regulatory Freeze Pending Review” directing agencies to refrain from proposing or other existing regulations or what impact itissuing any rules until the Biden Administration has reviewed and approved those rules.

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 owners plan to submit a request for termination of the consent decree.EGUs.
Notices of Violation Involving Co-Owned Units
In June 2000, the USEPA issued an NOV to the then DP&L-operated Stuart generating station (co-owned by AES Ohio Generation, Dynegy and AEP Generation) for alleged violations of the CAA. The NOV contained allegations consistent with NOVs and complaints that the USEPA had brought against numerous other coal-fired utilities in the Midwest. The NOV indicated the USEPA may: (1) issue an order requiring compliance with the requirements of the Ohio SIP; or (2) bring a civil action seeking injunctive relief and civil penalties of up to $27,500 per day for each violation. To date, neither action has been taken. DPL cannot predict the outcome of this matter.
In January 2015, DP&L received NOVs from the USEPA alleging violations in opacity at the Stuart and Killen generating stations in 2014. On February 15, 2017, the USEPA issued an NOV alleging violations in opacity at the Stuart generation stationStation in 2016. Operations at boththe Stuart and KillenStation have ceased.

Clean Water Act – Regulation of Water Discharge
On January 7, 2013, the Ohio EPA issued a final NPDES permit to the Stuart Station which included a compliance schedule for performing a study to justify an alternate thermal limitation or take undefined measures to meet certain temperature limits. On February 1, 2013, DP&L appealed various aspects of the final permit to the Environmental Review Appeals Commission. As a result of DPL’s decision to retire the Stuart Station we do not expect this to have a material impact on us.
Clean Water Act rules for Seleniumselenium.
On July 13, 2016,Notice of Potential Liability for Third Party Disposal Site
In December 2003, AES Ohio and other parties received notices that the USEPA published the final updated chronic aquatic life criterionconsidered AES Ohio and other parties PRPs for the pollutant selenium in freshwater per section 304(a)Tremont City Landfill site, located near Dayton, Ohio. On October 16, 2019, AES Ohio received another notice from the USEPA claiming that AES Ohio is a PRP for the portion of the CWA. The rule will be implemented after state rulemaking occurs, and requirements will be incorporated into NPDES permits with compliance schedules in some cases. Itsite known as the barrel fill.

Regulation of Waste Disposal
In 2002, DP&LAES Ohio and other parties received a special notice that the USEPA considered DP&LAES Ohio to be a PRP for the clean-up of hazardous substances at a third-party landfill known as the South Dayton Dump (“Landfill”). Several of the parties voluntarily accepted some of the responsibility for contamination at the Landfill and, in May 2010, three of those parties, Hobart Corporation, Kelsey-Hayes Company and NCR Corporation (“PRP Group”), filed a civil complaint in Ohio federal court (the “District Court”) against DP&LAES Ohio and numerous other defendants, alleging that the defendants contributed to the contamination at the landfill and were liable for contribution to the PRP group for costs associated with the investigation and remediation of the site.

While DP&LAES Ohio was able to get the initial case dismissed, the PRP Group subsequently, in 2013, entered into an additional Administrative Settlement Agreement and Order on Consent (“ASAOC”) with the USEPA relating to vapor intrusion and again filed suit against DP&LAES Ohio and other defendants. Trial for that issue was scheduled to be held in 2019, but the District Court recently vacated that trial date and it is unknown when it will be rescheduled. Plaintiffs also attempted to addadded an additional ASAOC they entered into in 2016 pertaining to the investigation and remediation of all hazardous substances present in the Landfill - potentially including undefined areas outside the original dump footprint - to the vapor intrusion trial proceeding. The District Court allowed the claim to be added to the litigation2013 vapor intrusion ASAOC settled in early 2020, but ruled that the 2016 ASAOC could notremains to be adjudicated until after completion of the remedial investigation feasibility study, which is expected to be complete years after the vapor intrusion trial.study.

Regulation of CCR
On October 19, 2015, a USEPA rule regulating CCR under the Resource Conservation and Recovery Act as nonhazardous solid waste became effective.effective (CCR Rule). The rule established nationally applicable minimum criteria for the disposal of CCR in new and currently operating landfills and surface impoundments, including location restrictions, 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 ("WINWIIN Act"), which includes provisions to implement the

CCR ruleRule through a state permitting program, or if the state chooses not to participate, a possible federal permit program. EPAThe USEPA has indicated that they will implement a phased approach to amending the CCR Rule. On February 20, 2020, the USEPA published a proposed rule to establish a federal CCR permit program that would operate in states without approved CCR permit programs. The USEPA has indicated that they will implement a phased approach to amending the CCR rule, which is ongoing. With the sale of our coal-fired generating stations, we expect that the impact of these regulations would be limited to our interest in OVEC.
The CCR Rule, current or proposed amendments to the CCR Rule, the results of groundwater monitoring data or the outcome of CCR-related litigation could have a material adverse effect on our results of operations, financial condition and cash flows.
On September 13, 2017,August 28, 2020, the USEPA indicatedpublished the CCR Part A Rule that, it would reconsideramong other amendments, required certain provisionsCCR units to cease waste receipt and initiate closure by April 11, 2021. The CCR Part A Rule also allowed for extensions of the April 11, 2021 deadline if EPA determines certain criteria are met. Facilities seeking such an extension were required to submit a demonstration to EPA by November 30, 2020. On January 11, 2022, EPA released pre-publication versions of proposed determinations regarding nine CCR Part A Rule demonstrations, including for OVEC’s Clifty Creek. On the same day, EPA issued four compliance-related letters notifying certain other facilities of their compliance obligations under the federal CCR regulations. The determinations and letters include interpretations regarding implementation of the CCR ruleRule. It is too early to determine the direct or indirect impact of these letters or any determinations that may be made.
Clean Water Act - Regulation of Water Discharge
AES Ohio and other utilities at times have applied the Nationwide Permit 12 (NWP 12) issued by the U.S. Army Corps of Engineers (Corps) in responsecompleting 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 July 6, 2020, the U.S. Supreme Court stayed the district court order, allowing the use of NWP 12 for oil and gas pipeline projects except for Keystone XL. On January 13, 2021, the U.S. Army Corps of Engineers published a final rulemaking for the reissuance and modification of NWPs, including NWP 12, relating exclusively to two petitions it receivedthe construction of oil or natural gas pipelines and the new NWP 57 for construction of electric or telecommunication utility lines. It is too early to reconsiderdetermine whether future outcomes or decisions related to this matter could have a material adverse effect on our results of operations, financial condition and cash flows.
On April 23, 2020, the final rule.U.S. Supreme Court issued a decision in the Hawaii Wildlife Fund v. 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 equivalent of a direct discharge from the point source into navigable waters. A number of legal cases relevant to the determination of "functional equivalent" are ongoing in various jurisdictions. It is too early to determine whether the CCRSupreme Court decision or the result of litigation related to "functional equivalent" may have a material adverse effect on our results of operations, financial condition and cash flows.

In June 2015, the USEPA and the U.S. Army Corps of Engineers ("the agencies") published a rule or any reconsiderationdefining federal jurisdiction over waters of the U.S., known as the "Waters of the U.S." (WOTUS) rule. This rule, which initially became effective in August 2015, could expand or otherwise change the number and types of waters or features subject to CWA permitting. However, after repealing the 2015 WOTUS rule on October 22, 2019, the agencies, on April 21, 2020, issued the final “Navigable Waters Protection” (NWP) rule which again revised the definition of waters of the U.S. On August 30, 2021, the U.S. District Court for the District of Arizona issued an order vacating and remanding the NWP Rule. This vacatur of the NWP Rule applies nationwide. As such, the agencies are interpreting waters of the U.S. consistent with the pre-2015 regulatory regime until further notice. On December 7, 2021, the Agencies published a proposed rule to define the scope of waters regulated under the Clean Water Act. The proposed rule would restore regulations defining WOTUS that were in place prior to 2015, with updates to be consistent with relevant Supreme Court decisions. A second rulemaking process is planned to further build upon this proposed rule. On January 24, 2022, the U.S. Supreme Court granted certiorari on a wetlands case (Sackett v. EPA) on the limited question of: “whether the Ninth Circuit set forth the proper test for determining whether wetlands are ‘waters of the United States’ under the Clean Water Act.” The Ninth Circuit employed Justice Kennedy’s “significant nexus” test from his concurring opinion in the 2006 Rapanos v. United States decision; the plurality opinion in Rapanos required a water body to have a “continuous surface connection” with a water of the United States in order to be considered a wetland covered by the CWA. In Sackett v. EPA, the Court may finally provide clarity on which of these two tests from the 2006 Rapanos decision controls. It is too early to determine whether any outcome of litigation or current or future revisions to rules interpreting federal jurisdiction over waters over the U.S. might have a material impact on our business, financial condition orand results of operations.
Notice of Violation Involving Co-Owned UnitsClimate Change Legislation and Regulation
On September 9, 2011, DP&L received an NOV from the USEPA with respectAlthough we have exited our generation business, our continuing operations face certain risks related to its co-owned Stuart generating station based onexisting and potential international, federal, state, regional and local GHG legislation and regulations, including risks related to increased capital expenditures or other compliance costs which could have a compliance evaluation inspection conducted by the USEPA and the Ohio EPA in 2009. The notice alleged non-compliance by DP&L with certain provisions of the RCRA, the CWA NPDES permit program and the station’s storm water pollution prevention plan. The notice requested that DP&L respond with the actions it has subsequently taken or plans to take to remedy the USEPA’s findings and ensure that further violations will not occur. Based on its review of the findings, although there can be no assurance, we believe that the notice will not result in any material adverse effect on DPL’sour results of operations, financial condition orand cash flows. Except as noted in the discussion below, at this time, we cannot estimate the costs of compliance with existing, proposed or potential international, federal, state or regional GHG emissions reductions legislation or initiatives due in part to the fact that many of these proposals are in earlier stages of development and any final laws or regulations, if adopted, could vary drastically from current proposals. Any international, federal, state or regional legislation adopted in the U.S. that would require the reduction of GHG emissions could have a material adverse effect on our business and/or results of operations, financial condition and cash flows.

On the international level, on December 12, 2015, 195 nations, including the U.S., finalized the text of an international climate change accord in Paris, France (the “Paris Agreement”), which agreement was signed and officially entered into on April 22, 2016. The Paris Agreement calls for countries to set their own GHG emissions targets, make these emissions targets more stringent over time and be transparent about the GHG emissions reporting and the measures each country will use to achieve its GHG emissions targets. A long-term goal of the Paris Agreement is to limit global temperature increase to well below two degrees Celsius from temperatures in the pre-industrial era. The U.S. withdrawal from the Paris Agreement became effective on November 4, 2020. However, on January 20, 2021, President Biden signed and submitted an instrument for the U.S. to rejoin the Paris Agreement, which became effective on February 19, 2021. In November 2021, the international community gathered in Glasgow at the 26th Conference to the Parties on the UN Framework Convention on Climate Change (“COP26”), during which multiple announcements were made, including a call for parties to eliminate certain fossil fuel subsidies and pursue further action on non-carbon dioxide GHGs.

Item 1A – Risk Factors
Investors should consider carefully the following risk factors that could cause our business, operating results and financial condition to be materially adversely affected. 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. The categories of
15

risk we have identified in Item 1A. — Risk Factors include risks associated with our operations, governmental regulation and laws and our indebtedness and financial condition. These risk factors should be read in conjunction with the other detailed information concerning DPL set forth in the Notes to DPL's Consolidated Financial Statements and concerning DP&LAES Ohio set forth in the Notes to DP&L'sAES Ohio's Financial Statements in Part II – Item 8 – Financial Statements and Supplementary Data and additional information in Part II – Item 7 – Management’sManagement's Discussion and Analysis of Financial Condition and Results of Operations herein. The risks and uncertainties described below are not the only ones that we face. In light of executing on our plan to exit generation, our generation business and the risks associated with that business have significantly lessened, such as risks associated with operations of generation plants and with greenhouse gas emission requirements.


We may not always be able to recover our costs to deliver electricity to our retail customers. RISKS ASSOCIATED WITH OUR OPERATIONS

The costs we can recover and the return on capital we are permitted to earn for certain aspects of our business are regulated and governed by the laws of Ohio and the rules, policies and procedurescurrent outbreak of the PUCO.
In Ohio, retail generation rates are not subject to cost-based regulation, whilenovel 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 transmission and distribution businesses are still regulated. Even though rate regulation is premisedsystems and other facilities, results of operations, financial condition and cash flows. Further, the spread of the COVID-19 outbreak has caused 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 full recoveryMarch 13, 2020 the United States declared a national emergency with respect to COVID-19.

The outbreak of prudentlyCOVID-19 has 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 have incurred costs and a reasonable rate of return on invested capital, there can be no assurance that the PUCO will agree that allexpect to continue to incur expenses relating to COVID-19, including expenses relating to events outside of our costs have been prudently incurred or are recoverable. On May 1, 2008, SB 221, an Ohio electric energy bill, was adopted that requires all Ohio distribution utilities to file either an ESP or an MRO and established a significantly excessive earnings test for Ohio public utilities that measures a utility’s earnings to determine whether there have been significantly excessive earnings during a given calendar year. There can be no assurance that the regulatory process in which rates are determined will always result in rates that will produce a full or timely recovery of our costs or permitted rates of return. Accordingly, the revenue DP&L receives may or may not match its expenses at any given time.

The impact of the laws, rules, policiesoutbreak continues to evolve and procedures that set or govern electric rates, permitted ratesmany countries, including the United States, have implemented various types of return, rate structures, operation of a competitive bid structure to supply retail generation service to SSO customers, reliability initiatives, capital expenditures and investments and the recovery of thesesocial distancing and other costs onmeasures to address the outbreak. In addition to contributing to economic slowdown or a fullrecession, COVID-19 or timely basis through rates, power market prices, and the frequency and timing of rate increases,another pandemic could have a material and adverse effecteffects on our results of operations, financial condition and cash flows.


Our increased costsflows due to, renewable energyamong other factors:

further decline in customer demand as a result of general decline in business activity;
further destabilization of the markets and energy efficiency requirements may not be fully recoverabledecline in business activity negatively impacting our customer growth or the future.
Ohio law contains annual targets for energy efficiency which begannumber of customers in 2009 and require increasing energy reductions each year compared to a baseline energy usage, up to 22.3% by 2027. Peak demand reduction targets began in 2009 with increases in required percentages each year, up to 7.75% by 2020. The renewable energy standards have increased our costs and are expected to continue to increase (and could materially increase) these costs. DP&L is entitled to recover costs associated with its renewable energy compliance costs,service territory as well as its energy efficiencyour customers’ ability to pay for our services when due (or at all);
delay or inability in obtaining regulatory actions and demand response programs. Ifoutcomes that could be material to our business, including for recovery of COVID-19 related expenses and losses such as uncollectible customer amounts and the review and approval of our applications, rates and charges by the PUCO;

negative impacts on the health of our essential personnel, especially if a significant number of them are unableaffected, and on our operations as a result of implementing stay-at-home, quarantine and other social distancing measures;
a deterioration in our ability to timelyensure business continuity during a disruption, including increased cybersecurity attacks related to the work-from-home environment;
delays or fully recoverinability 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.

We will continue to review and modify our plans as conditions change. Despite our efforts to manage and remedy these costs, itimpacts to us, their ultimate impact also depends on factors beyond our knowledge or control, including the
16

duration and severity of this outbreak as well as third-party actions taken to contain its spread and mitigate its public health effects.

COVID-19 continues to present material uncertainty which could have a material adverse effect onmaterially and adversely affect our transmission and distribution systems, results of operations, financial condition and cash flows. In addition, if we were found notTo 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 beour level of indebtedness, our need to generate sufficient cash flows to service our indebtedness and our ability to comply with the covenants contained in compliance with these standards, monetary penalties could apply. These penalties are not permitted to be recovered from customers and significant penalties could have a material adverse effect onthe agreements that govern our results of operations, financial condition and cash flows. The demand reduction and energy efficiency standards by design result in reduced energy and demand that could have a material adverse effect on our results of operations, financial condition and cash flows.indebtedness.


We may be negatively affected by a lack of growth or a decline in the number of customers.

Customer growth is affected by a number of factors outside our control, such as population changes, job and income growth, housing starts, new business formation and the overall level of economic activity. A lack of growth, or a decline, in the number of customers in our service territory could have a material adverse effect on our results of operations, financial condition and cash flows and may cause us to fail to fully realize anticipated benefits from investments and expenditures.

We are subject to numerous environmental laws, rules and regulations that require capital expenditures, increase our cost of operations, and may expose us to environmental liabilities.
We are subject to various federal, state, regional and local environmental protection and health and safety laws and regulations governing, among other things, the remediation of retired generation and other facilities, storage, handling, use, storage, disposal and transportation of coal combustion residuals and other materials, some of which may be defined as hazardous materials, the emission and discharge of hazardous and other materials into the environment; and the health and safety of our employees. Such laws, rules and regulations tend to become stricter over time, and we could also become subject to additional environmental laws, rules and regulations and other requirements in the future. Environmental laws, rules and regulations also require us to comply with inspections and obtain and comply with a wide variety of environmental licenses, permits, inspections and other governmental authorizations. These laws, rules and regulations often require a lengthy and complex process of obtaining and renewing licenses, permits and other governmental authorizations from federal, state and local agencies. If we are not able to timely comply with inspections and obtain, maintain or comply with all environmental laws, rules and regulations, and all licenses, permits and other government authorizations required to operate our business, then our operations could be prevented, delayed or subject to additional costs. A violation of environmental laws, rules, regulations, licenses, permits or other requirements can result in substantial fines, penalties, other sanctions, permit revocation, facility shutdowns, the imposition of stricter environmental standards and controls or other injunctive measures affecting operating assets. In addition, any actual or alleged violation of these laws, rules or regulations and other requirements may require us to expend significant resources to defend against any such actual or alleged violations. DPL owns an undivided interest in one generating station operated by our co-owner. As a non-controlling owner in this generating station, DPL is responsible for its pro rata share of expenditures for complying with environmental laws, rules, regulations, licenses, permits and other requirements, but has limited control over the compliance measures taken by our co-owner. Under certain environmental laws, we could also be held strictly, jointly and severally responsible for costs relating to contamination at our past or present facilities and at third-party waste disposal sites. We could also be held liable for human exposure to such hazardous substances or for other environmental damage.

In particular, we are subject to potentially significant remediation expenses, enforcement initiatives, private-party lawsuits and reputational risk associated with CCR. CCR, which consists of bottom ash, fly ash and air pollution control wastes generated at our current and former coal-fired generation plant sites, is currently handled and/or has been handled in the past in the following ways: placement in onsite CCR ponds; disposal and beneficial use in onsite and offsite permitted, engineered landfills; use in various beneficial use applications, including encapsulated uses and structural fill; and used in permitted offsite mine reclamation. CCR currently remains onsite at several of our facilities, including in CCR ponds. The USEPA's final CCR rule, which became effective in October 2015 and is currently subject to litigation and undergoing revisions by the USEPA, regulates CCR as nonhazardous solid waste and establishes national minimum criteria for existing and new CCR landfills, impoundments and ponds, including location restrictions, design and operating criteria, groundwater monitoring, corrective action and closure

requirements and post-closure care. On December 16, 2016, President Obama signed the Water Infrastructure Improvements for the Nation (WIIN) Act into law, 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 primary enforcement mechanisms for the CCR rule could be actions commenced by the USEPA, states and private lawsuits. Compliance with the CCR rule, amendments to the federal CCR rule, or other federal, state, or foreign rules or programs addressing CCR may require us to incur substantial costs. In addition, CCR, particularly with respect to its beneficial use and regulation as nonhazardous solid waste, has been the subject of interest from environmental non-governmental organizations and the media. Any of the foregoing could have a material adverse effect on our results of operations, financial condition and cash flows.

From time to time we are subject to enforcement and litigation actions for claims of noncompliance with environmental laws, rules and regulations or other environmental requirements. DPL cannot assure that it will be successful in defending against any claim of noncompliance. Any actual or alleged violation of these laws, rules, regulations and other requirements may require us to expend significant resources to defend against any such actual or alleged violations and expose us to unexpected costs. Our costs and liabilities relating to environmental matters could have a material adverse effect on our results of operations, financial condition and cash flows. See Item 1 - Business - Environmental Matters for a more comprehensive discussion of these and other environmental matters impacting us.

We are reliant upon the performance of a co-owner who operates our remaining co-owned operational EGU.
We co-own an EGU operated by one of our co-owners. Poor operational performance by our co-owner, misalignment of co-owners’ interests with our own or lack of control over costs (such as fuel costs) incurred at this station could have an adverse effect on us. In addition, any sale of this co-owned EGU by the co-owner to a third party could enhance the risk of a misalignment of interests, lack of cost control and other operational failures.

The use of non-derivative and derivative instruments in the normal course of business could result in losses that could negatively impact our results of operations, financial position and cash flows.
From time to time, we use non-derivative and derivative instruments, such as swaps, options, futures and forwards, to manage financial risks. These trades are affected by a range of factors, including fluctuations in interest rates and optimization opportunities. We have attempted to manage our risk exposure by establishing and enforcing risk limits and risk management policies. Despite our efforts, however, these risk limits and management policies may not work as planned and fluctuating prices and other events could adversely affect our results of operations, financial condition and cash flows. In the absence of actively quoted market prices and pricing information from external sources, the valuation of these instruments can involve management’s judgment or the use of estimates. As a result, changes in the underlying assumptions or use of alternative valuation methods could affect the reported fair value of some of these contracts. We could also recognize financial losses as a result of volatility in the market values of these contracts, a counterparty failing to perform or the underlying transactions which the instruments are intended to hedge failing to materialize, which could result in a material adverse effect on our results of operations, financial condition and cash flows.

The Dodd-Frank Act contains significant requirements related to derivatives that, among other things, could reduce the cost effectiveness of entering into derivative transactions.
In July 2010, The Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act) was signed into law. The Dodd-Frank Act contains significant requirements relating to derivatives, including, among others, a requirement that certain transactions be cleared on exchanges that would necessitate the posting of cash collateral for these transactions. We are considered an end-user under the Dodd-Frank Act and therefore are exempt from most of the collateral and margining requirements. We are required to report our bilateral derivative contracts, unless our counterparty is a major swap participant or has elected to report on our behalf. Even though we qualify for an exception from these requirements, our counterparties that do not qualify for the exception may pass along any increased costs incurred by them through higher prices and reductions in unsecured credit limits or be unable to enter into certain transactions with us. The occurrence of any of these events could have a material adverse effect on our results of operations, financial condition and cash flows.


Our business is sensitive to weather and seasonal variations.

Weather conditions significantly affect the demand for electric power and, accordingly, our business is affected by variations in general weather conditions and unusually severe weather. As a result of these factors, our operating revenues and associated operating expenses are not generated evenly by month during the year. We forecast electric sales based on the basis of normal weather, which represents a long-term historical average. In addition, severe or unusual weather, such as hurricanesfloods, tornadoes and ice or snow storms,snowstorms, may cause outages and property damage that may

require us to incur additional costs that may not be insured or recoverable from customers. While DP&LAES Ohio is permitted to seek recovery of storm damage costs, if DP&LAES Ohio is unable to fully recover such costs in a timely manner, it could have a material adverse effect on our results of operations, financial condition and cash flows.


Our membership in a regional transmission organization presents risks that could have a material adverse effect on our results of operations, financial condition and cash flows.

On October 1, 2004, in compliance with Ohio law, DP&LAES Ohio turned over control of its transmission functions and fully integrated into PJM, a regional transmission organization.


The rules governing the various regional power markets may also change from time to time which could affect our costs and revenues and have a material adverse effect on our results of operations, financial condition and cash flows. We may be required to expand our transmission system according to decisions made by PJM rather than our internal planning process. Various proposals and proceedings before the FERC may cause transmission rates to change from time to time. In addition, PJM developed and continues to refine rules associated with the allocation and methodology of assigning costs associated with improved transmission reliability, reduced transmission congestion and firm transmission rights that may have a financial effect on us. We also incur fees and costs to participate in PJM.


SB 221 includes a provision that allows electric utilities to seek and obtain recovery ofNon-market-based RTO-related charges. Therefore, non-market-based costscharges are being recovered from all retail customers through the transmission rider.Transmission Rider. If in the future, however, we are unable to recover all of these costs in a timely manner this could have a material adverse effect on our results of operations, financial condition and cash flows.


As members of PJM, DP&LAES Ohio and AES Ohio Generation are also subject to certain additional risks including those associated with the allocation of losses caused by unreimbursed defaults of other participants in PJM markets among PJM members and those associated with complaint cases filed against PJM that may seek refunds of revenues previously earned by PJM members including DP&LAES Ohio and AES Ohio Generation. These amounts could be significant and have a material adverse effect on our results of operations, financial condition and cash flows.

Costs associated with new transmission projects could have a material adverse effect on our results of operations, financial condition and cash flows.

Annually, PJM performs a review of the capital additions required to provide reliable electric transmission services throughout its territory. PJM traditionally allocated the costs of constructing these facilities to those entities that benefited directly from the additions. Over the last several years, however, some of the costs of constructing new large transmission facilities have been “socialized” across PJM without a direct relationship between the costs assigned to and benefits received by particular PJM members. To date, the additional costs charged to DP&LAES Ohio for new large transmission approved projects have not been material. Over time, as more new transmission projects are constructed and if the allocation method is not changed, the annual costs could become material. DP&LAES Ohio is recovering the Ohio retail jurisdictional share of these allocated costs from its retail customers through the transmission rider.Transmission Rider. To the extent that any costs in the future are material and we are unable to recover them from our customers, such costs could have a material adverse effect on our results of operations, financial condition and cash flows.

If we were found not to be in compliance with the mandatory reliability standards, we could be subject to sanctions, including substantial monetary penalties.
As an owner of a bulk power transmission system, DP&L is subject to mandatory reliability standards promulgated by the NERC and enforced by the FERC. The standards are based on the functions that need to be performed to ensure the bulk power system operates reliably and is guided by reliability and market interface principles. In addition, DP&L is subject to Ohio reliability standards and targets. Compliance with reliability standards may subject us to higher operating costs or increased capital expenditures. Although we expect to recover costs and expenditures from customers through regulated rates, there can be no assurance that the PUCO will approve full recovery in a timely manner. If we were found not to be in compliance with the mandatory reliability standards, we could be subject to sanctions, including substantial monetary penalties, which could have a material adverse effect on our results of operations, financial condition and cash flows.


We rely on access to the financial markets. General economic conditions and disruptions in the financial markets could adversely affect our ability to raise capital on favorable terms, or at all, and cause increases in our interest expense.
From time to time we rely on access to the capital and credit markets as a source of liquidity for capital requirements not satisfied by operating cash flows. These capital and credit markets experience volatility and disruption from time to time and the ability of corporations to raise capital can be negatively affected. Disruptions in the capital and credit markets make it harder and more expensive to raise capital. It is possible that our ability to raise capital on favorable terms, or at all, could be adversely affected by future market conditions, and we may be unable to access adequate funding to refinance our debt as it becomes due or finance capital expenditures. The extent of any impact will depend on several factors, including our operating cash flows, financial condition and prospects, the overall supply and demand in the credit markets, our credit ratings, credit capacity, the cost of financing, the financial condition, performance and prospects of other companies in our industry or with similar financial circumstances and other general economic and business conditions. It may also depend on the performance of credit counterparties and financial institutions with which we do business. Access to funds under our existing financing arrangements is also dependent on the ability of our counterparties to meet their financing commitments. Our inability to obtain financing on reasonable terms, or at all, with creditworthy counterparties could adversely affect our results of operations, financial condition and cash flows. If our available funding is limited or we are forced to fund our operations at a higher cost, these conditions may require us to curtail our business activities and increase our cost of funding, both of which could reduce our profitability. See Note 7 – Long-term debt of Notes to DPL's Consolidated Financial Statements and Note 7 – Long-term debt of Notes to DP&L's Financial Statements for information regarding indebtedness. See also Item 7A - Quantitative and Qualitative Disclosure about Market Riskfor information related to market risks.


Our transmission and distribution system is subject to operational, reliability and capacity risks.

The ongoing reliable performance of our transmission and distribution system is subject to risks due to, among other things, weather damage, intentional or unintentional damage, equipment or process failure, catastrophic events, such as fires and/or explosions, facility outages, labor disputes, accidents or injuries, operator error or inoperability of key infrastructure internal or external to us and events occurring on third party systems that interconnect to and affect our system. The failure of our transmission and distribution system to fully operate and deliver the energy demanded by customers could have a material adverse effect on our results of operations, financial condition and cash flows, and if such failures occur frequently and/or for extended periods of time, could result in adverse regulatory action. In addition, the advent and quick adoption of new products and services that require increased levels of electrical energy cannot be predicted and could result in insufficient transmission and distribution system capacity. Also, as a result of the above risks and other potential risks and hazards associated with transmission and distribution operations, we may from time to time become exposed to significant liabilities for which we may not have adequate insurance coverage. We maintain an amount of insurance protection that we believe is adequate, but there can be no assurance that our insurance will be sufficient or effective under all circumstances and against all hazards or liabilities to which we may be subject. Further, any increased costs or adverse changes in the insurance markets may cause delays or inability in maintaining insurance coverage on terms similar to those presently available to us or at all. A successful claim for which we are not fully insured could have a material adverse effect on our results of operations, financial condition and cash flows.


Current and future conditions in the economy may adversely affect our customers, suppliers and other counterparties, which maycould materially and adversely affect our results of operations, financial condition and cash flows.

Our business, results of operations, financial condition and cash flows have been and will continue to be affected by general economic conditions. Slowing economic growth, credit market conditions, fluctuating consumer and business confidence, fluctuating commodity prices and other challenges currently affecting the general economy, have caused and may continue to cause some of our customers to experience deterioration of their businesses, cash flow shortages and difficulty obtaining financing. As a result, existing customers may reduce their electricity consumption and may not be able to fulfill their payment obligations to us in a normal, timely fashion. In addition, some existing commercial and industrial customers may discontinue their operations. Sustained downturns, recessions or a sluggish economy generally affect the markets in which we operate and negatively influence our energy operations. A contracting, slow or sluggish economy could reduce the demand for energy in areas in which we are doing business. For example, during economic downturns, our commercial and industrial customers may see a decrease in demand for their products, which in turn may lead to a decrease in the amount of energy they require. Furthermore, projects which may result in potential new customers may be delayed until economic conditions improve. Some of our suppliers, customers, other counterparties and others with whom we transact business may also experience financial difficulties, which may impact their ability to fulfill their obligations to us or result in their declaring bankruptcy or similar insolvency-type proceedings.us. For example, our counterparties on

forward purchase contracts and financial institutions involved in our credit facility may become unable to fulfill their contractual obligations.obligations to us or result in their declaring bankruptcy or similar insolvency-like proceedings. We may not be able to enter into replacement agreements on terms as favorable as our existing agreements. Reduced demand for our electric services, failure by our customers to timely remit full payment owed to us and supply delays or unavailability could have a material adverse effect on our results of operations, financial

condition and cash flows. In particular, the projected economic growth and total employment in DP&L’sAES Ohio’s service territory are important to the realization of our forecasts for annual energy sales.

The level of our indebtedness, and the security provided for this indebtedness, could adversely affect our financial flexibility, and a material change in market interest rates could adversely affect our results of operations, financial condition and cash flows.
As of December 31, 2018, the carrying value of DPL's debt was $1,475.9 million and the carrying value of DP&L's debt was $586.1 million. Of DP&L's indebtedness, there was $576.1 million of First Mortgage Bonds, tax-exempt bonds and a term loan outstanding as of December 31, 2018, which are each secured by the pledge of substantially all of the assets of DP&L under the terms of DP&L’s First & Refunding Mortgage. This level of indebtedness and related security could have important consequences, including:

increasing our vulnerability to general adverse economic and industry conditions;
requiring us to dedicate a substantial portion of our cash flow from operations to make payments on our indebtedness, thereby reducing the availability of our cash flow to fund other corporate purposes;
limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and
limiting, along with the financial and other restrictive covenants in our indebtedness, our ability to borrow additional funds, as needed.

If DP&L issues additional debt in the future, we will be subject to the terms of such debt agreements and be required to obtain regulatory approvals. To the extent we increase our leverage, the risks described above would also increase. Further, actual cash requirements in the future may be greater than expected. Accordingly, our cash flows from operations may not be sufficient to repay all of the outstanding debt as it becomes due and, in that event, we may not be able to borrow money, sell assets or otherwise raise funds on acceptable terms, or at all, to refinance our debt as it becomes due. For a further discussion of our outstanding debt obligations, see Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations - Financial Condition, Liquidity and Capital Requirements and Note 7 – Long-term debt of Notes to DPL's Consolidated Financial Statements and Note 7 – Long-term debt of Notes to DP&L's Financial Statements.

DP&L has variable rate debt that bears interest based on a prevailing rate that is reset based on a market index that can be affected by market demand, supply, market interest rates and other market conditions. We also maintain both cash on deposit and investments in cash equivalents from time to time that could be impacted by interest rate fluctuations. As such, any event which impacts market interest rates could have a material effect on our results of operations, financial condition and cash flows. In addition, rating agencies issue ratings on our credit and our debt that affect our borrowing costs under our financial arrangements and affect our potential pool of investors and funding sources. Credit ratings also govern the collateral provisions of certain of our contracts. If the rating agencies were to downgrade our credit ratings further, our borrowing costs would likely further increase, our potential pool of investors and funding resources could be reduced, and we could be required to post additional collateral under select contracts. These events would likely reduce our liquidity and profitability and could have a material adverse effect on our results of operations, financial condition and cash flows.


Economic conditions relating to the asset performance and interest rates of our pension and postemployment benefit plans could materially and adversely impact our results of operations, financial condition and cash flows.

Pension costs are based upon a number of actuarial assumptions, including an expected long-term rate of return on pension plan assets, level of employer contributions, the expected life span of pension plan beneficiaries and the discount rate used to determine the present value of future pension obligations. Any of these assumptions could prove to be wrong, resulting in a shortfall of our pension and postemployment benefit plan assets compared to obligations under our pension and postemployment benefit plans. Further, the performance of the capital markets affects the values of the assets that are held in trust to satisfy future obligations under our pension and postemployment benefit plans. These assets are subject to market fluctuations and will yield uncertain returns, which may fall below our projected return rates. A decline in the market value of the pension and postemployment benefit plan assets will increase the funding requirements under our pension and postemployment benefit plans if the actual asset returns do not recover these declines in value in the foreseeable future. Future pension funding

requirements, and the timing of funding payments, may also be subject to changes in legislation. We are responsible for funding any shortfall of our pension and postemployment benefit plans’ assets compared to obligations under the pension and postemployment benefit plans, and a significant increase in our pension liabilities could materially and adversely impact our results of operations, financial condition and cash flows. We are subject to the Pension Protection Act of 2006, which requires underfunded pension plans to improve their funding ratios within prescribed intervals based on the level of their underfunding. As a result, our required contributions to these plans, at times, have increased and may increase in the future. In addition, our pension and postemployment benefit plan liabilities are sensitive to changes in interest rates. When interest rates decrease, the discounted liabilities increase benefit expense and funding requirements. Further, changes in demographics, including increased numbers of retirements or changes in life expectancy assumptions, may also increase the funding requirements for the obligations related to the pension and other postemployment benefit plans. Declines in market values and increased funding requirements could have a material adverse effect on our results of operations, financial condition and cash flows.


Counterparties providing materials or services may fail to perform their obligations, which could harmmaterially and adversely impact our results of operations, financial condition and cash flows.

We enter into transactions with and rely on many counterparties in connection with our business, including for purchased power, for our capital improvements and additions and to provide professional services, such as actuarial calculations, payroll processing and various consulting services. If any of these counterparties fails to perform its obligations to us or becomes unavailable, our business plans may be materially disrupted, we may be forced to discontinue certain operations if a cost-effective alternative is not readily available or we may be forced to enter into alternative arrangements at then-current market prices that may exceed our contractual prices and cause delays. Although our agreements are designed to mitigate the consequences of a potential default by the counterparty, our actual exposure may be greater than relief provided by these mitigation provisions. Any of the foregoing could result in regulatory actions, cost overruns, delays or other losses, any of which (or a combination of which) could have a material adverse effect on our results of operations, financial condition and cash flows.


Further, from time to time our construction program may callcalls for extensive expenditures for capital improvements and additions, including the installation of upgrades, improvements to transmission and distribution facilities, as well as other initiatives. As a result, we may engage contractors and enter into agreements to acquire necessary materials and/or obtain required construction related services. In addition, some contracts may provide for us to assume the risk of price escalation and availability of certain metals and key components. This could force us to enter into alternative arrangements at then-current market prices that may exceed our contractual prices andor cause construction delays.delays in a significant manner. It could also subject us to enforcement action by regulatory authorities to the extent that such a contractor failure resulted in a failure by DP&LAES Ohio to comply with requirements or expectations, particularly with regard to the cost of the project. If these events were to occur, we might incur losses or delays in completing construction.

Accidental improprieties and undetected errors in our internal controls and information reporting could result in the disallowance of cost recovery, noncompliant disclosure or incorrect payment processing.

Our internal controls, accounting policies and practices and internal information systems are designed to enable us to capture and process transactions and information in a timely and accurate manner in compliance with GAAP in the United States of America, laws and regulations, taxation requirements and federal securities laws and regulations in order to, among other things, disclose and report financial and other information in connection with the recovery of our costs and with our reporting requirements under federal securities, tax and other laws and regulations and to properly process payments. We have also implemented corporate governance, internal control and accounting policies and procedures in connection with the Sarbanes-Oxley Act of 2002. Our internal controls and policies have been and continue to be closely monitored by management and our Board of Directors. While we believe these controls, policies, practices and systems are adequate to verify data integrity, unanticipated and unauthorized actions of employees, temporary lapses in internal controls due to shortfalls in oversight or resource constraints could lead to improprieties and undetected errors that could result in the disallowance of cost recovery, noncompliant disclosure and reporting or incorrect payment processing. The consequences of these events could have a material adverse effect on our results of operations, financial condition and cash flows.

New accounting standards or changes to existing accounting standards could materially affect how we report our results of operations, financial condition and cash flows.
DPL's Consolidated Financial Statements and DP&L's Financial Statements are prepared in accordance with accounting principles generally accepted in the United States of America. The SEC, FASB or other authoritative bodies or governmental entities may issue new pronouncements or new interpretations of existing accounting standards that may require us to change our accounting policies. These changes are beyond our control, can be

difficult to predict and could materially affect how we report our results of operations, financial condition and cash flows. We could be required to apply a new or revised standard retroactively, which could adversely affect our financial condition. In addition, in preparing our Financial Statements, management is required to make estimates and assumptions. Actual results could differ significantly from those estimates.

We are subject to extensive laws and local, state and federal regulation, as well as litigation and other proceedings that could affect our operations and costs.
As an electric utility, DP&L is subject to extensive regulation at both the federal and state level. For example, at the federal level, DP&L is regulated by the FERC and the NERC and, at the state level, by the PUCO. The regulatory power of the PUCO over DP&L is both comprehensive and typical of the traditional form of regulation generally imposed by state public utility commissions. We face the risk of unexpected or adverse regulatory action. Regulatory discretion is reasonably broad in Ohio. DP&L is subject to regulation by the PUCO as to our services and facilities, the valuation of property, the construction, purchase, or lease of electric facilities, the classification of accounts, rates of depreciation, the increase or decrease in retail rates and charges, the issuance of securities and incurrence of debt, the acquisition and sale of some public utility properties or securities and certain other matters. As a result of the Energy Policy Act of 2005 and subsequent legislation affecting the electric utility industry, we have been required to comply with rules and regulations in areas including mandatory reliability standards, cybersecurity, transmission expansion and energy efficiency. Complying with the regulatory environment to which we are subject requires us to expend a significant amount of funds and resources. The failure to comply with this regulatory environment could subject us to substantial financial costs and penalties and changes, either forced or voluntary, in the way we operate our business that could have a material adverse effect on our results of operations, financial condition and cash flows.

We may be subject to material litigation, regulatory proceedings, administrative proceedings, audits, settlements, investigations and claims from time to time which may require us to expend significant funds to address. There can be no assurance that the outcome of these matters will not have a material adverse effect on our business, results of operations, financial condition and cash flows. Asbestos and other regulated substances are, and may continue to be, present at our facilities, and we have been named as a defendant in asbestos litigation. The continued presence of asbestos and other regulated substances at these facilities could result in additional litigation being brought against us, which could have a material adverse effect on our results of operations, financial condition and cash flows. See Item 1 - Business - Competition and Regulation, Item 1 - Business - Environmental Matters, and Item 3 - Legal Proceedings for a summary of significant regulatory matters and legal proceedings involving us.

Tax legislation initiatives or challenges to our tax positions could adversely affect our operations and financial condition.
We are subject to the tax laws and regulations of the U.S. federal, state and local governments. From time to time, legislative measures may be enacted that could adversely affect our overall tax positions regarding income or other taxes. There can be no assurance that our effective tax rate or tax payments will not be adversely affected by these legislative measures.

For example, the United States federal government recently enacted tax reform that, among other things, reduces U.S. federal corporate income tax rates, imposes limits on tax deductions for interest expense and changes the rules related to capital expenditure cost recovery. There are a number of uncertainties and ambiguities as to the interpretation and application of many of the provisions of the newly enacted tax reform measure. Given the unpredictability of these possible changes and their potential interdependency, it remains difficult to assess the overall effect such tax changes will have on our earnings and cash flow, and the extent to which such changes could adversely impact our results of operations. As the impacts of the new law are determined, and as yet-to-be-released regulations and other guidance interpreting the new law are issued and finalized, our financial results could be materially impacted.

In addition, U.S. federal, state and local tax laws and regulations are extremely complex and subject to varying interpretations. There can be no assurance that our tax positions will be sustained if challenged by relevant tax authorities and if not sustained, there could be a material adverse effect on our results of operations, financial condition and cash flows.


If we are unable to maintain a qualified and properly motivated workforce, it could have a material adverse effect on our results of operations, financial condition and cash flows.

One of the challenges we face is to retain a skilled, efficient and cost-effective workforce while recruiting new talent to replace losses in knowledge and skills due to resignations, terminations or retirements. This undertaking could

require us to make additional financial commitments and incur increased costs. If we are unable to successfully attract and retain an appropriately qualified workforce, it could have a material adverse effect on our results of operations, financial condition and cash flows. In addition, we have employee compensation plans that reward the performance of our employees. We seek to ensure that our compensation plans encourage acceptable levels for risk and high performance through pay mix, performance metrics and timing. We may not be able to successfully train new personnel as current workers with significant knowledge and expertise retire. We also may be unable to staff our business with qualified personnel in the event of significant absenteeism related to a pandemic illness. Excessive risk-taking by our employees to achieve performance targets, through mitigated by policies and procedures, could result in events that have a material adverse effect on our results of operations, financial condition and cash flows.


We are subject to collective bargaining agreements that could adversely affect our business, results of operations, financial condition and cash flows.

We are subject to collective bargaining agreements with employees who are members of a union. Over half of our employees are represented by a collective bargaining agreement that expires on October 31, 2020.agreement. While we believe that we maintain a satisfactory relationship with our employees, it is possible that labor disruptions affecting some or all of our operations could occur during the period of the collective bargaining agreement or at the expiration of the collective bargaining agreement before a new agreement is negotiated. Work stoppages by, or poor relations or ineffective negotiations with, our employees or other workforce issues could have a material adverse effect on our results of operations, financial condition and cash flows.


The use of non-derivative and derivative instruments in the normal course of business could result in losses that could materially and adversely impact our results of operations, financial position and cash flows.

From time to time, we use non-derivative and derivative instruments, such as swaps, options, futures and forwards, to manage financial risks. These trades are affected by a range of factors, including fluctuations in interest rates and optimization opportunities. We have attempted to manage our risk exposure by establishing and enforcing risk limits and risk management policies. Despite our efforts, however, these risk limits and management policies may not work as planned and fluctuating prices and other events could adversely affect our results of operations, financial condition and cash flows. In the absence of actively quoted market prices and pricing information from external sources, the valuation of these instruments can involve management’s judgment or the use of estimates. As a result, changes in the underlying assumptions or use of alternative valuation methods could affect the reported fair value of some of these contracts. We could also recognize financial losses as a result of volatility in the market values of these contracts, a counterparty failing to perform or the underlying transactions which the instruments are

intended to hedge failing to materialize, which could result in a material adverse effect on our results of operations, financial condition and cash flows.

Potential security breaches (including cybersecurity breaches) and terrorism risks could materially and adversely affect our businesses.

We operate in a highly regulated industry that requires the continued operation of sophisticated systems and network infrastructure at our generation stations, fuel storage facilitiestransmission, distribution and transmission and distributionother facilities. We also use various financial, accounting and other systems in our businesses. These systems and facilities are vulnerable to unauthorized access due to hacking, viruses, other cybersecurity attacks and other causes. In particular, given the importance of energy and the electric grid, there is the possibility that our systems and facilities could be targets of terrorism or acts of war. We have implemented measures to help prevent unauthorized access to our systems and facilities, including network and system monitoring, identification and deployment of secure technologies and certain other measures to comply with mandatory regulatory reliability standards. Pursuant to NERC requirements, we have a robust cybersecurity plan in place and are subject to regular audits by an independent auditor approved by the NERC. We routinely test our systems and facilities against these regulatory requirements in order to measure compliance, assess potential security risks and identify areas for improvement. In addition, we provide cybersecurity training for our employees and perform exercises designed to raise employee awareness of cyber risks on a regular basis. To date, cyber-attacks on our business and operations have not had a material impact on our operations or financial results. Despite these efforts, if our systems or facilities were to be breached or disabled, we may be unable to recover them in a timely manner to fulfill critical business functions, including the supply of electric services to our customers, and we could experience decreases in revenues and increases in costs that could have a material adverse effect onmaterially and adversely affect our results of operations, financial condition and cash flows.flows


In the course of our business, we also store and use customer, employee and other personal information and other confidential and sensitive information, including personally identifiable information and personal financial information. If our or our third-party vendors’ systems were to be breached or disabled, sensitive and confidential information and other data could be compromised, which could result in negative publicity, remediation costs and potential litigation, damages, consent orders, injunctions, fines and other relief.


To help mitigate these risks, we maintain insurance coverage against some, but not all, potential losses, including coverage for illegal acts against us. However, insurance may not be adequate to protect us against all costs and liabilities associated with these risks.


RISKS ASSOCIATED WITH GOVERNMENTAL REGULATION AND LAWS

We may not always be able to recover our costs to deliver electricity to our retail customers. The costs we can recover and the return on capital we are permitted to earn for the most substantial part of our business are regulated and governed by the laws of Ohio and the rules, policies and procedures of the PUCO.

In Ohio, transmission and distribution businesses are regulated. Even though rate regulation is premised on full recovery of prudently incurred costs and a reasonable rate of return on invested capital, there can be no assurance that the PUCO will agree that all of our costs have been prudently incurred or are recoverable. There can be no assurance that the regulatory process in which rates are determined will always result in rates that will produce a full or timely recovery of our costs or permitted rates of return. Accordingly, the revenue AES Ohio receives may or may not match its expenses at any given time.

Changes in or reinterpretations of, or the unexpected application of the laws, rules, policies and procedures that set or govern electric rates, permitted rates of return, rate structures, operation of a competitive bid structure to supply retail generation service to SSO customers, reliability initiatives, capital expenditures and investments and the recovery of these and other costs on a full or timely basis through rates, power market prices and the frequency and timing of rate increases, could have a material adverse effect on our results of operations, financial condition and cash flows.

Our increased costs due to renewable energy and energy efficiency requirements may not be fully recoverable in the future.

Ohio law contains annual targets for energy efficiency which began in 2009 and require increasing energy reductions each year compared to a baseline energy usage, up to 22.3% by 2027. Peak demand reduction targets

Table of Contents
began in 2009 with increases in required percentages each year, up to 7.75% by 2020. The renewable energy standards have increased our costs and are expected to continue to increase (and could materially increase) these costs. AES Ohio is currently entitled to recover costs associated with its renewable energy compliance, as well as its energy efficiency and demand response programs. If, in the future, we are unable to timely or fully recover these costs, it could have a material adverse effect on our results of operations, financial condition and cash flows. In addition, if we were found not to be in compliance with these standards, monetary penalties could apply. These penalties are not permitted to be recovered from customers and significant penalties could have a material adverse effect on our results of operations, financial condition and cash flows. The demand reduction and energy efficiency standards by design result in reduced energy and demand that could have a material adverse effect on our results of operations, financial condition and cash flows.

We are subject to numerous environmental laws, rules and regulations that require capital expenditures, increase our cost of operations and may expose us to environmental liabilities.

We are subject to various federal, state, regional and local environmental protection and health and safety laws and regulations governing, among other things, the remediation of retired generation and other facilities, storage, handling, use, storage, disposal and transportation of coal combustion residuals and other materials, some of which may be defined as hazardous materials, the emission and discharge of hazardous and other materials or items into the environment, such as GHGs; and the health and safety of our employees. Such laws, rules and regulations can become stricter over time, and we could also become subject to additional environmental laws, rules and regulations and other requirements in the future. Environmental laws, rules and regulations also require us to comply with inspections and obtain and comply with a wide variety of environmental licenses, permits, inspections and other governmental authorizations. These laws, rules and regulations often require a lengthy and complex process of obtaining and renewing licenses, permits and other governmental authorizations from federal, state and local agencies. If we are not able to timely comply with inspections and obtain, maintain or comply with all environmental laws, rules and regulations and all licenses, permits and other government authorizations required to operate our business, then our operations could be prevented, delayed or subject to additional costs. A violation of environmental laws, rules, regulations, licenses, permits or other requirements can result in substantial fines, penalties, other sanctions, permit revocation, facility shutdowns, the imposition of stricter environmental standards and controls or other injunctive measures affecting operating assets. In addition, any actual or alleged violation of these laws, rules or regulations and other requirements may require us to expend significant resources to defend against any such actual or alleged violations. AES Ohio has an ownership interest in OVEC, which operates generating stations. We generally are responsible for our respective pro rata share of expenditures for complying with environmental laws, rules, regulations, licenses, permits and other requirements at this generating station, but have limited control over the compliance measures taken by the operator. Under certain environmental laws, we could also be held strictly, jointly and severally responsible for costs relating to contamination at our past or present facilities and at third-party waste disposal sites. We could also be held liable for human exposure to such hazardous substances or for other environmental damage.

In particular, we are subject to potentially significant remediation expenses, enforcement initiatives, private-party lawsuits and reputational risk associated with CCR, which consists of bottom ash, fly ash, boiler slag and flue gas desulfurization materials generated from burning coal generated at our formerly owned coal-fired generation plant sites. CCR currently remains onsite at OVEC's EGUs, including in CCR ponds. Compliance with the CCR rule, amendments to the federal CCR rule, or other federal, state, or foreign rules or programs addressing CCR may require us to incur substantial costs. In addition, CCR, particularly with respect to its beneficial use and regulation as nonhazardous solid waste, has been the subject of interest from environmental non-governmental organizations and the media. Any of the foregoing could have a material adverse effect on our results of operations, financial condition and cash flows.

From time to time we are subject to enforcement and litigation actions for claims of noncompliance with environmental laws, rules and regulations or other environmental requirements. We cannot assure that we will be successful in defending against any claim of noncompliance. Any actual or alleged violation of these laws, rules, regulations and other requirements may require us to expend significant resources to defend against any such actual or alleged violations and expose us to unexpected costs. Our costs and liabilities relating to environmental matters could have a material adverse effect on our results of operations, financial condition and cash flows. See Item 1 - Business - Environmental Matters for a more comprehensive discussion of these and other environmental matters impacting us.

Concerns about GHG emissions and the potential risks associated with climate change have led to increased regulation and other actions that could impact our business.

Although we have exited our generation business, our continuing operations face risks from regulatory developments related to climate change, as well as the physical impacts of climate change. At the federal, state and regional levels, policies are under development or have been developed to regulate GHG emissions. There currently is no U.S. federal legislation imposing mandatory GHG emission reductions (including for CO2) that affects our current operations. In addition, it is likely that there will be increased focus on climate change from a President Biden administration and a Democrat-controlled U.S. Congress, both of which may result in additional legislation and regulations regarding GHG emissions.

In December 2015, the parties to the United Nations Framework Convention on Climate Change convened for the 21st Conference of the parties and the resulting Paris Agreement established a long-term goal of keeping the increase in global average temperature well below 2°C above pre-industrial levels. We anticipate that the Paris Agreement will continue the trend toward efforts to de-carbonize the global economy. Although the U.S. was officially able to withdraw from the Paris Agreement on November 4, 2020, on January 20, 2021, President Biden began the 30-day process of rejoining the Paris Agreement, which became effective for the U.S. on February 19, 2021. In November 2021, the international community gathered in Glasgow at the 26th Conference to the Parties on the UN Framework Convention on Climate Change (COP26), during which multiple announcements were made, including a call for parties to eliminate certain fossil fuel subsidies and pursue further action on non-carbon dioxide GHGs.

Any existing or future international, federal, state or regional legislation or regulation of GHG emissions, to the extent directly or indirectly applicable to our electric transmission and distribution operations, could have a material adverse impact on our financial performance.

Furthermore, according to the Intergovernmental Panel on Climate Change, physical risks from climate change could include, but are not limited to, increased runoff and earlier spring peak discharge in many glacier and snow-fed rivers, warming of lakes and rivers, an increase in sea level, changes and variability in precipitation and in the intensity and frequency of extreme weather events. Physical impacts may have the potential to significantly affect our business and operations. For example, extreme weather events could result in increased downtime and operation and maintenance costs at our electric power transmission and distribution assets and facilities. Variations in weather conditions, primarily temperature and humidity, would also be expected to affect the energy needs of customers. A decrease in energy consumption could decrease our revenues. In addition, while revenues would be expected to increase if the energy consumption of customers increased, such increase could prompt the need for additional investment in generation capacity.

If any of the foregoing risks materialize, we expect our costs to increase or revenues to decrease and there could be a material adverse effect on our business and on our consolidated results of operations, financial condition, cash flows and reputation if such changes are significant. Please see “Item 1. Business - Environmental Matters” for additional information of environmental matters impacting us, including those relating to regulation of GHG emissions.

If we were found not to be in compliance with the mandatory reliability standards, we could be subject to sanctions, including substantial monetary penalties.

As an owner of a bulk power transmission system, AES Ohio is subject to mandatory reliability standards promulgated by the NERC and enforced by the FERC. The standards are based on the functions that need to be performed to ensure the bulk power system operates reliably and is guided by reliability and market interface principles. In addition, AES Ohio is subject to Ohio reliability standards and targets. Compliance with reliability standards may subject us to higher operating costs or increased capital expenditures. Although we expect to recover costs and expenditures from customers through regulated rates, there can be no assurance that the PUCO will approve full recovery in a timely manner. If we were found not to be in compliance with the mandatory reliability standards, we could be subject to sanctions, including substantial monetary penalties, which could have a material adverse effect on our results of operations, financial condition and cash flows.

The failure to comply with this regulatory environment could subject us to substantial financial costs and penalties and changes, either forced or voluntary, in the way we operate our business that could have a material adverse effect on our results of operations, financial condition and cash flows.

We are subject to litigation, regulatory proceedings, administrative proceedings, audits, settlements, investigations and claims from time to time that require us to expend significant funds to address. There can be no assurance that the outcome of these matters will not have a material adverse effect on our business, results of operations, financial condition and cash flows. Asbestos and other regulated substances are, and may continue to be, present at our facilities, and we have been named as a defendant in asbestos litigation. The continued presence of asbestos and other regulated substances at these facilities could result in additional litigation being brought against us, which could have a material adverse effect on our results of operations, financial condition and cash flows. See Item 1 - Business - Competition and Regulation, Item 1 - Business - Environmental Matters, and Item 3 - Legal Proceedings for a summary of significant regulatory matters and legal proceedings involving us.

Tax legislation initiatives or challenges to our tax positions could adversely affect our operations and financial condition.

We are subject to the tax laws and regulations of the U.S. federal, state and local governments. From time to time, legislative measures may be enacted that could adversely affect our overall tax positions regarding income or other taxes. There can be no assurance that our effective tax rate or tax payments will not be adversely affected by these legislative measures.

In addition, U.S. federal, state and local tax laws and regulations are extremely complex and subject to varying interpretations. There can be no assurance that our tax positions will be sustained if challenged by relevant tax authorities and if not sustained, there could be a material adverse effect on our results of operations, financial condition and cash flows.

RISKS RELATED TO OUR INDEBTEDNESS AND FINANCIAL CONDITION

The level of our indebtedness, and the security provided for this indebtedness, could adversely affect our financial flexibility, and a material change in market interest rates could adversely affect our results of operations, financial condition and cash flows.

As of December 31, 2021, the carrying value of DPL's debt was $1,460.5 million and the carrying value of AES Ohio's debt was $574.3 million. Of AES Ohio's indebtedness, there was $565.0 million of First Mortgage Bonds as of December 31, 2021, which are secured by the pledge of substantially all of the assets of AES Ohio under the terms of AES Ohio’s First & Refunding Mortgage. DPL's revolving credit facility is also secured by a pledge of common stock that DPL owns in AES Ohio. This level of indebtedness and related security has important consequences, including:

increasing our vulnerability to general adverse economic and industry conditions;
requiring us to dedicate a substantial portion of our cash flow from operations to make payments on our indebtedness, thereby reducing the availability of our cash flow to fund other corporate purposes;
24

Table of Contents
limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and
limiting, along with the financial and other restrictive covenants in our indebtedness, our ability to borrow additional funds, as needed.

If AES Ohio issues additional debt in the future, we will be subject to the terms of such debt agreements and be required to obtain regulatory approvals. To the extent we increase our leverage, the risks described above would also increase. Further, actual cash requirements in the future may be greater than expected. Accordingly, our cash flows from operations may not be sufficient to repay all of the outstanding debt as it becomes due and, in that event, we may not be able to borrow money, sell assets or otherwise raise funds on acceptable terms, or at all, to refinance our debt as it becomes due. Additionally, any failure to comply with covenants in the instruments governing our debt could result in an event of default thereunder. For a further discussion of our outstanding debt obligations, see Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations - Financial Condition, Liquidity and Capital Requirements and Note 6 – Long-term debt of Notes to DPL's Consolidated Financial Statements and Note 6 – Long-term debt of Notes to AES Ohio's Financial Statements.

DPL and AES Ohio have variable rate debt that bears interest based on a prevailing rate that is reset based on a market index that can be affected by market demand, supply, market interest rates and other market conditions. We also maintain both cash on deposit and investments in cash equivalents from time to time that could be impacted by interest rate fluctuations. As such, any event which impacts market interest rates could have a material effect on our results of operations, financial condition and cash flows. In addition, rating agencies issue ratings on our credit and our debt that affect our borrowing costs under our financial arrangements and affect our potential pool of investors and funding sources. Credit ratings also govern the collateral provisions of certain of our contracts. If rating agencies downgrade our credit ratings further, our borrowing costs would likely further increase, our potential pool of investors and funding resources could be reduced, and we could be required to post additional collateral under select contracts. These events would likely reduce our liquidity and profitability and could have a material adverse effect on our results of operations, financial condition and cash flows.

We rely on access to the financial markets. General economic conditions and disruptions in the financial markets could adversely affect our ability to raise capital on favorable terms, or at all, and cause increases in our interest expense.

From time to time we rely on access to the capital and credit markets as a source of liquidity for capital requirements not satisfied by operating cash flows. These capital and credit markets experience volatility and disruption from time to time and the ability of corporations to raise capital can be negatively affected. Disruptions in the capital and credit markets make it harder and more expensive to raise capital. Our ability to raise capital on favorable terms, or at all, can be adversely affected by unfavorable market conditions or declines in our creditworthiness, and we may be unable to access adequate funding to refinance our debt as it becomes due or finance capital expenditures. The extent of any impact will depend on several factors, including our operating cash flows, financial condition and prospects, the overall supply and demand in the credit markets, our credit ratings, credit capacity, the cost of financing, the financial condition, performance and prospects of other companies in our industry or with similar financial circumstances and other general economic and business conditions. It may also depend on the performance of credit counterparties and financial institutions with which we do business. Access to funds under our existing financing arrangements is also dependent on the ability of our counterparties to meet their financing commitments and our satisfying conditions to borrowing. Our inability to obtain financing on reasonable terms, or at all, with creditworthy counterparties could adversely affect our results of operations, financial condition and cash flows. If our available funding is limited or we are forced to fund our operations at a higher cost, these conditions may require us to curtail our business activities and increase our cost of funding, both of which would adversely impact our profitability. See Note 6 – Long-term debt of Notes to DPL's Consolidated Financial Statements and Note 6 – Long-term debt of Notes to AES Ohio's Financial Statements for information regarding indebtedness. See also Item 7A - Quantitative and Qualitative Disclosure about Market Riskfor information related to market risks.

DPL is a holding company and parent of DP&LAES Ohio and other subsidiaries. DPL’s cash flow is dependent on the operating cash flows of DP&LAES Ohio and its other subsidiaries and their ability to pay cash to DPL.

DPL is a holding company with no material assets other than the ownership of its subsidiaries, and accordingly all cash is generated by the operating activities of its subsidiaries, principally DP&LAES Ohio. As such, DPL’s cash flow is largely dependent on the operating cash flows of DP&LAES Ohio and its ability to pay cash to DPL. See Item 7 - Management’s DiscussionThe impact of the December 2019

See Note 3 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements and Note 3 – Regulatory Matters of Notes to DP&L's Financial Statements for more information the regulatory environment. As part of the PUCO’s approval of the Merger, DP&L agreed to maintain certain capital structure levels. See Note 10 – Equity of Notes to DPL's Consolidated Financial Statements and Note 10 – Equity of Notes to DP&L's Financial Statements for information related to these capital structure levels and restrictions on DP&L's equity and its ability to declare and pay dividends to DPL. While we do not expect any of the foregoing to significantly affect DP&L’s ability to pay funds to DPL in the near future, aA significant limitation on DP&L’sAES Ohio’s ability to pay dividends or loan or advance funds to DPL could have a material adverse effect on DPL’s results of operations, financial condition and cash flows. In addition, as a result of any non-compliance with PUCO requirements, the PUCO could impose additional restrictions on DP&L operations that could have a material adverse effect on our results of operations, financial condition and cash flows.


Our ownership by AES subjects us to potential risks that are beyond our control.

All of DP&L’sAES Ohio’s common stock is owned by DPL, and DPL is an indirectly wholly owned subsidiary of AES. Due to our relationship with AES, any adverse developments and announcements concerning AES may impair our ability to access the capital markets and to otherwise conduct business. In particular, downgrades in AES’s credit ratings could result in DPL’s or DP&L’sAES Ohio’s credit ratings being downgraded.


Impairment of long-lived assets would negatively affect our consolidated results of operations and net worth.
Long-lived assets are amortized or depreciated over their estimated useful lives. Long-lived assets are evaluated for impairment only when impairment indicators are present. The recoverability assessment of long-lived assets requires making estimates and assumptions to determine fair value, as described above. See Note 17 – Fixed-asset impairments or Notes to DPL's Consolidated Financial Statements for more information on the impairment of fixed assets.

Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with DPL’s audited Consolidated Financial Statements and the related Notes thereto and DP&L’sAES Ohio’s audited Financial Statements and the related Notes thereto included in Item 8 – Financial Statements and Supplementary Data of this Form 10-K. The following discussion contains forward-looking statements. Our actual results may differ materially from the results suggested by these forward-looking statements. See “Forward-Looking Statements” at the beginning of this Form 10-K and Item 1A – Risk Factors. For a list of certain abbreviations or acronyms in this discussion, see Glossary of Terms at the beginning of this Form 10-K.


OVERVIEW OF 2021 RESULTS AND STRATEGIC PERFORMANCE

The most important matters on which we focus in evaluating our financial condition and operating performance and allocating our resources include: (i) recurring factors which have significant impacts on operating performance such as: regulatory action, environmental matters, weather and weather-related damage in our service area, customer growth, and the local economy; (ii) our progress on performance improvement and growth strategies designed to maintain high standards in several operating areas (including safety, customer satisfaction, operations, financial and enterprise-wide performance, talent management/people, capital allocation/sustainability and corporate social responsibility) simultaneously; and (iii) our short-term and long-term financial and operating strategies. For a discussion of how we are impacted by regulation and environmental matters, please see Note 2 – Regulatory Matters of the Notes to DPL's Consolidated Financial Statements, Note 2 – Regulatory Matters of the Notes to AES Ohio's Financial Statements and “Environmental Matters” in “Item 1 - Business.”

Operational Excellence

Our objective is to optimize AES Ohio’s performance in the U.S. utility industry by focusing on the following areas: safety, operations (reliability and customer satisfaction), financial and enterprise-wide performance (efficiency and cost savings, talent management/people, capital allocation/sustainability and corporate social responsibility). We set and measure these objectives carefully, balancing them in a way and to a degree necessary to ensure a sustainable high level of performance in these areas simultaneously compared to our peers. We monitor our performance in these areas, and where practical and meaningful, compare performance in some areas to peer utilities. Because some of our financial and enterprise-wide performance measures are company-specific performance goals, they are not benchmarked.

Our safety performance is measured by both leading and lagging metrics. Our leading safety metrics track safety observations, safety meeting engagement and the reporting of non-injury significant injury potential incidents. Our lagging safety metrics track lost workday cases, severity rate, and recordable incidents. We are committed to excellence in safety and have implemented various programs to increase safety awareness and improve work practices.

AES Ohio measures delivery reliability by Customer Average Interruption Duration Index ("CAIDI"), System Average Interruption Duration Index ("SAIDI") and System Average Interruption Frequency Index ("SAIFI") and benchmarks the reliability metrics against other utilities at both the state and national levels. AES Ohio also measures customer centricity on more of an individual basis by the industry metric of Customers that Experience Multiple Interruption of five or more times (“CEMI-5”). We measure customer satisfaction using Research America Utilities Market Research - Consumer Insight. Monitoring performance in the areas such as competitive rates, operational reliability and customer service supports our ongoing work to deliver reliable service to our customers.

EXECUTIVE SUMMARY


The following review of results of operations compares the results for the year ended December 31, 2021 to the results for the year ended December 31, 2020.

DPL – Revenues
Retail customers, especially residential and commercial customers, consume more electricity on warmer and colder days. Therefore, our retail sales volumedemand 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. Additionally, our retail revenues are affected by regulated rates and riders, including the changes to our ESP, described in Note 2 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements.

Heating and Cooling Degree-days (a)

(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.

either by sale or retirement within the last year.retired in 2018 and sold in 2019, and Conesville, which was retired in May 2020 and sold in June 2020. See Part II, Item 8, Note 1514 – Discontinued Operations in the Notes to DPL's Consolidated Financial Statements.Statements for further discussion.



RESULTS OF OPERATIONS BY SEGMENT DPL Inc.


Beginning with the second quarter of 2018, DPL has presented the results of operations of Miami Fort Station, Zimmer Station, the Peaker Assets, Stuart Station and Killen Station as discontinued operations as a group of components for all periods presented. For more information, see Note 15 – Discontinued Operations of Notes to DPL's Consolidated Financial Statements. AES Ohio Generation now only has operating activity coming from its undivided ownership interest in Conesville, which does not meet the threshold to be a separate reportable operating segment. Because of this, DPL now manages its business through only 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 segments. The Utility segment is discussed further below:

Table of Contents

Utility Segment
The Utility segment is comprised primarily 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 525,000534,000 retail customers who are located in a 6,000 square6,000-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 and recordsrecording 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’s Beckjord Facility,AES Ohio’s Hutchings Coal Station, which was closed in 20142013 and transferred to a third party in the firstfourth quarter of 2018, and the Hutchings EGU, which was closed in 2013. These assets did not transfer to AES Ohio Generation as part of DP&L's Generation Separation on October 1, 2017. Thus, they are grouped within the Utility segment for segment reporting purposes. In addition, regulatory deferrals and collections, which include fuel deferrals in historical periods, are included in the Utility segment.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 andas well as adjustments related to purchase accounting from the Merger.DPL's undivided interest in Conesville is now included within the "Other" column as it no longer meets the requirement for disclosure as a reportable operating segment, since the results of operations of the other generation plants are now presented as discontinued operations. The accounting policies of the reportable segments are the same as those described in Note 1 – Overview and Summary of Significant Accounting Policies. Intersegment sales, costs of sales and profitsexpenses are eliminated in consolidation. Certain shared and corporate costs are allocated amongbetween "Other" and the Utility reporting segments.segment.

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 this Form 10-K.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. Additionally, our retail revenues are affected by regulated rates and riders, including the changes to our ESP, described in Note 2 – Regulatory Matters of Notes to AES Ohio's Financial Statements.

KEY TRENDS AND UNCERTAINTIES


Following the issuance of the DRO in September 2018During 2022 and the resulting changes to the decoupling rider effective January 1, 2019,beyond, we expect that our financial results will no longer be driven primarily by retail demand and weather but will be impacted by customer growth within our service territory. See further discussion on these changesweather. As discussed in Note 32 – Regulatory Mattersof Notes to DPL's Consolidated Financial Statements and Note 2 – Regulatory Matters of Notes to DPL's ConsolidatedAES Ohio's 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 distribution rate order. If approved, the deferral would be effective as of December 18, 2019 and Note 3 – Regulatory Mattersgoing forward would reduce impacts of Notes to DP&L's Financial Statements.weather, energy efficiency programs and economic changes in customer demand. In addition, DPL's and DP&L's AES 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 regulations; and
timely recovery of transmission and distribution expenditures;expenditures.

COVID-19 Pandemic
The COVID-19 pandemic has impacted global economic activity, including electricity and energy consumption, and caused significant volatility in financial markets. Responses to the COVID-19 pandemic by the State of Ohio and its residents and businesses continue to evolve as virus variants emerge, vaccine availability and usage continues and the state and businesses review and adjust the scope and requirements of social distancing measures.
exiting generation assets currently owned by AES Ohio Generation.

Operational
As partSocial 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 the 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 announced plancontrol. We experienced impacts from the pandemic in 2021 and into 2022 and expect to exitcontinue to experience impacts for the remainder of 2022. The following discussion highlights our generation businesses,assessment of the impacts of the COVID-19 pandemic on May 31, 2018,our current financial and operating status, and our financial and operational outlook based on information known as of this filing. Any impacts in future periods could have material and adverse effects on our results of operations, financial condition and cash flows. Also see "Item 1A. Risk Factors" of this Form 10-K.

Business Continuity - During the COVID-19 pandemic, we retiredare taking a variety of measures to ensure our ability to transmit, distribute and sell electric energy, to ensure the Stuarthealth and Killen EGUs. In addition, we closed on a salesafety of our Peaker assetsemployees, 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 stay-at-home restrictions have been lifted in our service territory, most 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. We prioritize the safety of our people and continue to develop targeted strategies, in line with legal and regulatory requirements, to promote vaccination in our business.

Demand - As the economic impact of the COVID-19 pandemic started to materialize in Ohio in March 2018. See2020 and continued for the duration of 2020 and into 2021, the COVID-19 pandemic primarily impacted our retail sales demand. Retail sales demand decreased in 2020 mostly from commercial and industrial customers, but started to recover in 2021 as shown by the changes in weather-normalized volumes of kWh sold by customer class as follows:

As noted above, we also have incurred and expect to continue to incur expenses relating to COVID-19, however see Note 15 - Discontinued Operations in the2 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements for additional information. In October 2018, AEP,a discussion of regulatory measures which partially mitigate the operatorimpact of these expenses. While we have continued to experience COVID-19 impacts into 2022, we continue to expect that such impacts would not be material, particularly if less expansive social distancing measures and improvements in energy demand continue. The magnitude and duration of the co-owned Conesville EGU,COVID-19 pandemic is unknown at this time, however, and could have material and adverse effects on our results of operations, financial condition and cash flows in future periods.

Liquidity - We anticipate having sufficient liquidity to make all required payments, including payments for salaries and wages owed to our employees, during the pandemic. We do not foresee a significant impact to our access to capital or our liquidity position as a result of the pandemic. For further discussion of our financial condition, liquidity, and capital requirements, see Part II, Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations - Capital Resources and Liquidity of this Form 10-K.

Credit Exposures - We continue to monitor and manage our credit exposures in a prudent manner. During the year ended 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. AES Ohio implemented and continues to offer extended payment plans to customers during the pandemic. In 2021, collections improved and credit-related impacts were not significant. If credit-related impacts from the COVID-19 pandemic occur in 2022 or beyond, deterioration in our credit exposures and customer collections could result. However, as discussed in Note 2 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements and Note 2 – Regulatory Matters of Notes to AES Ohio's Financial Statements in Item 8. - Financial Statements and Supplementary Data of our Form 10-K, AES Ohio’s uncollectible expense is deferred for future collection.

Supply Chain - We continue to closely manage and monitor developments in our supply chain. We are experiencing certain minor delays and price increases, but these have not materially impacted our operations or capital projects to date.

Capital Projects - During the COVID-19 pandemic, our construction projects have experienced some indications of delays and price increases; however, they are currently proceeding without material delays. For further discussion of our capital requirements, see Part II, Item 7 – Management's Discussion and Analysis of Financial Condition and Results of Operations – Capital Resources and Liquidity of this Form 10-K.

CARES Act - The Coronavirus Aid, Relief, and Economic Security ("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, we deferred the payment of federal payroll taxes in accordance with the provisions of this act. The total deferred was approximately $2.1 million, and at December 31, 2021, the total remaining unpaid balance was approximately $1.1 million, which will be paid in 2022.

Macroeconomic and Political


United States Tax LawReference Rate Reform

In December 2017, the U.S. federal government enacted the TCJA. The legislation significantly revised the U.S. corporate income tax system by, among other things, lowering corporate income tax rates and introducing new limitations on interest expense deductions beginning in 2018. These changes will materially impact our effective tax rate in future periods. Specific provisions of the TCJA and their potential impacts on us are noted below. Our interpretation of the TCJA may change as the U.S. Treasury Department and the Internal Revenue Service issue additional guidance. Such changes may be material.
Lower Tax Rate - The corporate tax rate decreased from 35 percent to 21 percent beginning in 2018. In addition to deferred tax remeasurement impacts, the lower tax rate resulted in the recognition, at December 31, 2017, of a regulatory liability at DP&L. The regulatory liability reflects deferred taxes that will flow back to ratepayers over time. For further details, see Deferred income taxes payable through rates of Note 3 – Regulatory Matters and Note 8 – Income Taxes of Notes to DPL's Consolidated Financial Statements and "Deferred income taxes payable through rates of Note 3 – Regulatory Matters and Note 8 – Income Taxes of Notes to DP&L's Financial Statements.
SAB 118 - As further explained in Note 8 – Income Taxes of Notes to DPL's Consolidated Financial Statements and Note 8 – Income Taxes of Notes to DP&L's Financial Statements, we have concluded our analysis of the implementation impacts of the TCJA and included adjustments to our previous estimates in accordance with the guidance of SAB 118.
Limitation on Interest Expense Deductions - The TCJA introduced a new limitation on the deductibility of net interest expense beginning January 1, 2018. The deduction is limited to interest income, plus 30 percent of tax basis EBITDA through 2021 (30 percent of EBIT beginning January 1, 2022). This determination is made at the

consolidated group level. The limitation does not apply to interest expense attributable to regulated utility property. The U.S. Treasury Department and Internal Revenue Service have released proposed regulations to clarify how the exception will apply to regulated utility holding companies. These proposed regulations are prospective; we have not adopted them for 2018.
Cost Recovery -The TCJA amended depreciation rules to provide full expensing (100% bonus depreciation) for assets that commence construction and are placed in service before January 1, 2023. This provision is phased down by 20 percent ratably through 2027. The immediate full expensing provision is elective, but it does not apply to regulated utility property. This change is not expected to impact our effective tax rate; however, if elected, it could impact taxable income and cash taxes in future periods.
State Taxes -The reactions of the individual states to federal tax reform is still evolving. These state and municipalities will assess whether and how the federal changes will be incorporated into their tax legislation.
On January 10, 2018 the PUCO initiated a proceeding to consider the impacts of the TCJA to determine the appropriate course of action to pass benefits resulting from the legislation on to ratepayers. The PUCO also directed Ohio utilities to record deferred liabilities for the estimated reduction in federal income tax resulting from the TCJA beginning January 1, 2018. Under the terms of the ESP, DPL will not make tax sharing payments and if our rates are reduced as a result of the TCJA, DPL's cash flows could be adversely affected. See Note 8 – Income Taxes of Notes to DPL's Consolidated Financial Statements and Note 8 – Income Taxes of Notes to DP&L's Financial Statements for more information.

LIBOR Phase Out

In July 2017, the U.K.UK Financial Conduct Authority announced thethat it intends to phase out of LIBOR by the end of 2021. TheIn the U.S., the Alternative Reference Rate Committee withinat the Federal Reserve is responsibleidentified the Secured Overnight Financing Rate ("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 transition fromovernight, one-month, three-month, six-month, and 12-month USD LIBOR rates through June 30, 2023. The IBA expects to a new benchmark replacement rate. While wemake separate announcements in this regard following the outcome of the consultation. We maintain financial instruments that use LIBOR as an interest rate benchmark and will continue to engage with counterparties to make this transition.

Inflation - In the full impactmarkets in which we operate, there have been higher rates of inflation in recent months. If inflation continues to increase in our markets, it may increase our expenses that we may not be able to pass through to customers. AES Ohio may have the phase out is uncertain until a new replacement benchmark is determinedability to recover operations and maintenance costs through the regulatory process, however, timing impacts on recovery may vary.
implementation plans are more fully developed.


Regulatory Environment
For a comprehensive discussion of the market structure and regulation of DPL and DP&LAES Ohio, see Part I, Item 1 - Business – Competition and Regulation.


In December 2018, DP&LDistribution Rate Case - On November 30, 2020, AES Ohio filed a Distribution Modernization Plan (“DMP”)new distribution rate case with the PUCO. This rate case proposes a revenue increase of $120.8 million. A hearing on this case was held beginning in January 2022 and the case is pending a commission order.

Stipulation and Recommendation - On October 23, 2020, AES Ohio entered into a Stipulation and Recommendation (the Settlement) with the staff of the PUCO proposingand various customers, and organizations representing customers of AES Ohio and certain other parties with respect to, invest $576.0 million in capital projects over the next 10 years. There are eight principal components of DP&L’s DMP: 1) Smart Meters, 2) Self-Healing Grid, 3) Customer Engagement, 4) Enhancing Sustainability and Embracing Innovation. 5) Telecommunications, 6) Physical and Cyber Security, 7) Governance and Analytics, and 8) Grid Modernization R&D.

On January 22, 2019, DP&L filed a request withamong other matters, AES Ohio’s applications pending at the PUCO for a two-year extension(i) approval of AES Ohio’s plan to modernize its DMR through October 2022,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 satisfies the SEET and the more favorable in the proposed amountaggregate (MFA) regulatory test. A hearing was held in January 2021 for consideration of $199.0 million for each of the two additional years. The request was made pursuant to the PUCO’s October 20, 2017 ESP order, which approved the DMRthis settlement and had the option for DP&L to file for a two-year extension. The extension request was set at a level expected to reduce debt obligations at both DP&L and DPL and to position DP&L to make capital expenditures to maintain and modernize its electric grid. To that end, DP&L’s DMP investments are contingent uponon June 16, 2021, the PUCO approvingissued their opinion and order accepting the two-year extensionstipulation as filed.

Ohio House Bill 6 – Legislation was passed, Ohio House Bill 128, that repeals Ohio House Bill 6 provisions 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 AES Ohio, may defer, recover or credit the net proceeds from selling energy and capacity received as part of its DMR.their interest in OVEC and their OVEC-related costs through a statewide non-bypassable recovery mechanism 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 are repealed without a replacement with comparable provisions, it could have a material adverse effect on our results of operations, financial condition and cash flows.

CAPITAL RESOURCES AND LIQUIDITY


Cash,As of December 31, 2021, cash, cash equivalents and restricted cash for DPL and DP&LAES Ohio was $111.7$26.7 million and $66.2$14.5 million, respectively, and available borrowing capacity at DPL and AES Ohio was $35.0 million and $175.0 million, respectively.DPL and AES Ohio had aggregate principal amounts of long-term debt outstanding of $1,412.8 million and $582.2 million, respectively, at December 31, 2018. At that date, neither DPL nor DP&L had short-term investments. DPL and DP&L had aggregate principal amounts of debt outstanding of $1,488.4 million and $593.8 million, respectively, at December 31, 2018.2021.

Approximately $103.6 million of DPL's debt and $4.6 million of DP&L's debt matures within the next twelve months, which we expect to repay using a combination of cash on hand, net cash provided by operating activities and/or net proceeds from the issuance of new debt. 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 or otherwise could have material adverse effects on our financial condition and results of operations. In addition, changes in the timing of tariff increases or delays in the regulatory
43

determinations as well as unfavorable regulatory outcomes could affect the cash flows andhave a material adverse effect on our results of operations, offinancial condition and cash flows. See "RISKS ASSOCIATED WITH GOVERNMENTAL REGULATION AND LAWS" and "RISKS RELATED TO OUR INDEBTEDNESS AND FINANCIAL CONDITION" in Part I, Item 1a - Risk Factors and "COMPETITION AND REGULATION" in Part I, Item 1 - Business. From time to time, we may elect to repurchase our business.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.


DP&LAES Ohio must first seek approval from the PUCO to issue new stocks, bonds, notes and other evidences of indebtedness. Annually, DP&LAES Ohio must receive authority to issue and assume liability on short-term debt, not to exceed 12 months, pursuant to Section 4905.401 of themonths. AES Ohio Revised Code. DP&L received an order from the PUCO on December 15, 2021 granting authority through December 31, 20192022 to, among other things, issue up to $300.0 million in aggregate principal amount of short-term indebtedness. DP&LAES Ohio must also receive authority to issue and assume liability on long-term debt, in excess of 12 months, pursuant to Section 4905.40 of themonths. AES Ohio Revised Code. DP&L last received approval in 20162020 to, among other things, issue up to $455.0$140.0 million in aggregate principal amount of long-term indebtedness for a term not to exceed 30 years at an interest rate not to exceed 6.60%. DP&LFirst Mortgage Bonds. AES Ohio also has restrictions on the amount of new debt that may be issued due to contractual obligations of AES and by financial covenant restrictions under existing debt obligations. DP&LAES Ohio does not believe such restrictions will be a limiting factor in our ability to issue debt in the ordinary course of prudent business operations. In 2019, DP&L filed for approval to, among other things, issue up to $425.0 million in aggregate principal amount of long-term indebtedness for a term not to exceed 40 years at an interest rate not to exceed 5.75%.

Liquidity
We expect our existing sources of liquidity to remain sufficientcash balances, cash generated from operating activities and borrowing capacity on our existing credit facilities will be adequate to meet our anticipated operating needs.needs, including interest expense on our debt and any dividends to our equity owners. Our business is capital intensive, requiring significant resources to fund operating expenses, construction expenditures, scheduled debt maturities and carrying costs, potential margin requirements related to energy hedges, taxes and any dividend payments. For 20192022 and subsequent years, we expect to satisfy these requirements with a combination of cash from operations, and funds from debt financing and funds from equity capital contributions as our internal liquidity needs and market conditions warrant. We also expect that the borrowing capacity under bank credit facilitiesthe DPL Credit Agreement and the AES Ohio Credit Agreement will continue to be available to manage working capital requirements during those periods. In addition, DP&L's 2017 ESP provides for a DMR, which will be used for debt obligations at DPL and DP&L. See Note 3 – Regulatory Matters for more information.

At December 31, 2018, DPL and DP&L have access to the following revolving credit facilities:
$ in millions Type Maturity Commitment Amounts available as of December 31, 2018

DP&L's revolving credit facility has a commitmentThe absence of $175.0 million, with a $50.0 million letter of credit sublimit and a feature that provides DP&L theadequate liquidity could adversely affect our ability to increase the size of the facility by an additional $100.0 millionoperate our business and extending the term of the facility from May 2018 to July 2020. At December 31, 2018, DP&L had nothing drawn under this facility and had one letter of credit in the amount of $1.1 million outstanding, with the remaining $173.9 million available to DP&L. Fees associated with this facility were not material during the years ended December 31, 2018, 2017 or 2016.

DPL has a revolving credit facility of $205.0 million, with a $200.0 million letter of credit sublimit and a feature that provides DPL the ability to increase the size of the facility by an additional $95.0 million. This facility is secured by a pledge of common stock that DPL owns in DP&L, limited to the amount permitted to be pledged under certain Indentures dated October 3, 2011 and October 6, 2014 between DPL and Wells Fargo Bank, NA and U.S. Bank National Association, respectively, as Trustee and a limited recourse guarantee by AES Ohio Generation secured by assets of AES Ohio Generation. DPL further secured the credit facility through a leasehold mortgage on additional assets of AES Ohio Generation. The facility expires in July 2020; however, DPL's credit facility has a springing maturity feature providing that if, before July 1, 2019, DPL has not refinanced its senior unsecured bonds due October 2019 to have a maturity date that is at least six months later than July 31, 2020, then the maturity of this facility shall be July 1, 2019. At December 31, 2018, there were five letters of credit in the aggregate amount of $14.0 million outstanding under this facility, and nothing borrowed on the facility, with the remaining $191.0 million available to DPL. Fees associated with this facility were not material during the years ended December 31, 2018, 2017 or 2016.

Capital projects are subject to continuing review and are revised in light of changes in financial and economic conditions, load forecasts, legislative and regulatory developments and changing environmental laws, rules and regulations, among other factors.

DPL is projecting to spend an estimated $628.0 million in capital projects for the period 2019 through 2021, which includes expected spending under DP&L's Distribution Modernization Plan ("DMP") filed with the PUCO in December 2018. DP&L's 2017 ESP also provided for a DMR to pay debt obligations at DPL and DP&L and position DP&L to modernize and/or maintain its transmission and distribution infrastructure. See Note 3 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements and Note 3 – Regulatory Matters of Notes to DP&L's Financial Statements for more information. On January 22, 2019, DP&L filed a request with the PUCO for a two-year extension of its DMR through October 2022, in the proposed amount of $199.0 million for each of the two additional years. The request was made pursuant to the PUCO’s October 20, 2017 ESP order, which approved the DMR and had the option for DP&L to file for a two-year extension. The extension request was set at a level expected to reduce debt obligations at both DP&L and DPL and to position DP&L to make capital expenditures to maintain and modernize its electric grid. To that end, DP&L’s DMP investments are contingent upon the PUCO approving the two-year extension of its DMR.

DP&L is subject to the mandatory reliability standards of NERC and Reliability First Corporation (RFC), one of the eight NERC regions, of which DP&L is a member. NERC has recently changed the definition of the Bulk Electric System to include 100 kV and above facilities, thus expanding the facilities to which the reliability standards apply. DP&L’s 138 kV facilities were previously not subject to these reliability standards. Accordingly, DP&L anticipates spending approximately $221.0 million within the next five years to reinforce its 138-kV system to comply with these new NERC standards. Our ability to complete capital projects and the reliability of future service will be affected by our financial condition, the availability of internal funds and the reasonable cost of external funds. We expect to finance our construction additions with a combination of cash on hand, short-term financing, long-term debt and cash flows from operations.

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 certain contracts. These events may have an adverse effect on our results of operations, financial condition and cash flows.

AES Ohio is subject to the mandatory reliability standards of NERC and ReliabilityFirst Corporation, one of the six NERC regions, of which AES Ohio is a member. AES Ohio anticipates spending approximately $78.0 million within the next five years to reinforce its transmission system to comply with mandatory NERC and FERC Form 715 planning requirements. These anticipated costs are included in the overall capital projections above.

Debt Covenants
For information regarding our long-term debt covenants, see Note 6 – Long-term debt of Notes to DPL's Consolidated Financial Statements and Note 6 – Long-term debt of Notes to AES Ohio's Financial Statements.

Credit Ratings
Our ability to borrow money or to refinance existing indebtedness and the interest rates at which we can borrow money or refinance existing indebtedness are affected by our credit ratings. In addition, any suchthe applicable interest rates on DPL’s Credit Agreement and AES Ohio’s Credit Agreement (as well as the amount of certain other fees in the agreements) are dependent upon the credit ratings of DPL and AES Ohio. Downgrades in the credit ratings of AES could result in DPL's or AES Ohio’s credit ratings being downgraded. Any reduction in our debt or credit ratings may adversely affect the trading price of our outstanding debt securities. Non-investment grade companies may experience higher costs to issue new securities.

Off-Balance Sheet Arrangements


DPL – Guarantees
In the normal course of business, DPL enters into various agreements with its wholly-owned subsidiary, AES Ohio Generation, providing financial or performance assurance to third parties. These agreements are entered into primarily to support or enhance the creditworthiness otherwise attributed to these subsidiaries on a stand-alone basis, thereby facilitating the extension of sufficient credit to accomplish this subsidiary's intended commercial purposes. During the year ended December 31, 2018, DPL did not incur any losses related to the guarantees of these 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 December 31, 2018, DPL had $23.6 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 present and future obligations of AES Ohio Generation to such beneficiaries and are terminable at any time by DPL upon written notice to the beneficiaries. We had no outstanding balance of obligations for commercial transactions covered by these guarantees at December 31, 2018. The carrying amount of obligations for commercial transactions covered by these guarantees and recorded in our Consolidated Balance Sheets was $0.9 million at December 31, 2017.

DP&L owns a 4.9% equity ownership interest in OVEC which is recorded using the cost method of accounting under GAAP. At December 31, 2018, DP&L2021, AES Ohio could be responsible for the repayment of 4.9%, or $68.1$55.5 million, of a $1,389.6$1,131.7 million debt obligation comprised of both fixed and variable rate securities with maturities between 20192022 and 2040. This would only happen if this electric generation companyOVEC defaulted on its debt payments. At December 31, 2018,2021, we have no knowledge of such a default.

Patterson Air Force Base (WPAFB)WPAFB note. These long-term debt amounts include current maturities but exclude unamortized debt discounts, premiums and fair value adjustments.


DP&L’sAES Ohio’s Long-term debt at December 31, 20182021 consists of its First Mortgage Bonds, tax-exempt First Mortgage Bonds and the WPAFB note. These long-term debt amounts include current maturities but exclude unamortized debt discounts.


See Note 76 – Long-term debt of the Notes to DPL's Consolidated Financial Statements and Note 76 – Long-term debt of the Notes to DP&L'sAES Ohio's Financial Statements.


Interest payments:
Interest payments are associated with the long-term debt described above. The interest payments relating to variable-rate debt are projected using the interest rates in effect at December 31, 2018.2021.

Pension and postretirement payments:
At December 31, 2018, DPL, through its principal subsidiary DP&L, had estimated future benefit payments as outlined in Note 9 – Benefit Plans of Notes to DPL's Consolidated Financial Statements and Note 9 – Benefit Plans of Notes to DP&L's Financial Statements. These estimated future benefit payments are projected through 2028. This amount also includes postretirement benefit costs.


Electricity purchase commitments:
DPL enters into long-term contracts for the purchase of electricity. In general, these contracts are subject to variable quantities or prices and are terminable only in limited circumstances.


Purchase orders and other contractual obligations:
At December 31, 2018, 2021, DPL and DP&LAES Ohio had various other contractual obligations including non-cancelable contracts to purchase goods and services with various terms and expiration dates. Due to uncertainty regarding the timing and payment of future obligations to the Service Company, and DPL's and DP&L'sAES Ohio's ability to terminate such obligations upon 90 days' notice, we have excluded such amounts in the contractual obligations table above. SeeThis table also does not include:

Reserve for uncertain tax positions:
Due to the uncertainty regarding the timing of future cash outflows associated with our unrecognized tax benefits of $3.5$0.4 million at December 31, 2018,2021, we are unable to make a reliable estimate of the periods of cash settlement with the respective tax authorities and have not included such amounts in the contractual obligations table above.


CRITICAL ACCOUNTING POLICIES AND ESTIMATES


DPL’s Consolidated Financial Statements and DP&L’sAES Ohio’s 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. Our significant accounting policies are described in Note 1 – Overview and Summary of Significant Accounting Policies of Notes to DPL's Consolidated Financial Statements and Note 1 – Overview and Summary of Significant Accounting Policies of Notes to DP&L'sAES Ohio's Financial Statements.


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 allowances for deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; the valuation of AROs; and assets and liabilities related to employee benefits.



Revenue Recognition (including Unbilled Revenue)
Revenue is primarily earned from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transferAt the end of controleach month, amounts of promised goods or servicesenergy delivered to customers since the date of the last meter reading are estimated and the corresponding unbilled revenue is accrued. In making our estimates of unbilled revenue, we use complex models that consider various factors including known amounts of energy usage by nearly all residential, small commercial and industrial customers; estimated line losses; and estimated customer rates based on prior period billings. Given the use of these models, and that customers are billed on a monthly cycle, we believe it is unlikely that materially different results will occur in an amount that reflectsfuture periods when revenue is billed. The effect on 2021 revenues and ending unbilled revenues of a one percentage point change in estimated line losses for the consideration to which we expect to be entitled in exchangemonth of December 2021 is immaterial. An allowance for those goods or services. Revenuepotential credit losses is recorded net of any taxes assessed onmaintained and collected from customers, whichamounts are remitted to the governmental authorities.written off when normal collection efforts have been exhausted.


Income Taxes
We are subject to federal and state income taxes. Our income tax provision requires significant judgment and is based on calculations and assumptions that are subject to examination by the U.S. Internal Revenue Service and other tax authorities. We regularly assess the potential outcome of tax examinations when determining the adequacy of our income tax provisions by considering the technical merits of the filing position, case law and results of previous tax examinations. Accounting guidance for uncertainty in income taxes prescribes a more-likely-than-not recognition threshold and measurement requirements for financial statement reporting of our income tax positions. Tax reserves have been established which we believe to be adequate in relation to the potential for additional
49

Table of Contents
assessments. Once established, reserves are adjusted only when there is more information available or when an event occurs necessitating a change to the reserves. While we believe that the amount of the tax reserves is reasonable, it is possible that the ultimate outcome of current or future examinations may be materially different than the reserve amounts.

Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of the existing assets and liabilities, and their respective income tax bases. We establish a valuation allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized.


Regulatory Assets and Liabilities
Application of the provisions of GAAP relating to regulatory accounting requires us to reflect the effect of rate regulation in DPL’s Consolidated Financial Statements and DP&L’sAES Ohio’s Financial Statements. For regulated businesses subject to federal or state cost-of-service rate regulation, regulatory practices that assign costs to accounting periods may differ from accounting methods generally applied by non-regulated companies. When it is probable that regulators will permit the recovery of current costs through future rates charged to customers, we defer these costs as Regulatory assets that otherwise would be expensed by non-regulated companies. Likewise, we recognize Regulatory liabilities when it is probable that regulators will require customer refunds through future rates and when revenue is collected from customers for expenses that are not yet incurred. Regulatory assets are amortized into expense and Regulatory liabilities are amortized into income over the recovery period authorized by the regulator.


We evaluate our Regulatory assets to determine whether or not they are probable of recovery through future rates and make various assumptions in our analyses. The expectations of future recovery are generally based on orders issued by regulatory commissions or historical experience, as well as discussions with applicable regulatory authorities. If recovery of a regulatory asset is determined to be less than probable, it will be expensed in the period the assessment is made. We currently believe the recovery of our Regulatory assets is probable. See Note 32 – Regulatory Matters of Notes to DPL's Consolidated Financial Statements and Note 32 – Regulatory Matters of Notes to DP&L'sAES Ohio's Financial Statements.


AROsPension and Postretirement Benefits
In accordance with the provisions of GAAP relating to the accounting for AROs, legal obligations associated with the retirement of long-lived assets are required to be recognized at their fair value at the time those obligations are incurred. Upon initial recognition of a legal liability, costs are capitalized as part of the related long-lived asset and allocated to expense over the useful life of the asset. These GAAP provisions also require that components of previously recorded depreciation related to the cost of removal of assets upon future retirement, whether legal AROs or not, must be removed from a company’s accumulated depreciation reserve and be reclassified as a regulatory liability. We make assumptions, estimates and judgments that affect the reported amounts of assets, liabilities and expenses as they relate to AROs. These assumptions and estimates are based on historical experience and assumptions that we believe to be reasonable at the time. See Note 41Property, PlantOverview and EquipmentSummary of Significant Accounting Policies of Notes to DPL's Consolidated Financial Statements and Note 41Property, PlantOverview and EquipmentSummary of Significant Accounting Policies of Notes to DP&L'sAES Ohio's Financial Statements for more information.


Impairments
In accordance with the provisions of GAAP relating to theinformation on our accounting for impairments, long-lived assets are reviewed for impairment whenever events or circumstances indicate that the carrying amount may not be recoverable. When required, impairment losses on assets to be held and used are recognized based on the fair value of the asset group. Impairment losses on assets held-for-sale are recognized based on the fair value of the disposal group. We determine the fair value of these assets based upon estimates of future cash flows, market value of similar assets, if available, or independent appraisals, if required. In analyzing the fair value and recoverability using future cash flows, we make projections based on a number of assumptions and estimates of growth rates, future economic conditions, assignment of discount rates and estimates of terminal values. An impairment loss is recognized if the carrying amount of the long-lived asset is not recoverable from its undiscounted cash flows. The measurement of impairment loss is the difference between the carrying amount and fair value of the asset.

policies regarding Pension and Postretirement BenefitsBenefits.
We account for and disclose pension and postemployment benefits in accordance with the provisions of GAAP relating to the accounting for pension and other postemployment plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost, and funding requirements of the plans. See Note 9 – Benefit Plans of Notes to DPL's Consolidated Financial Statements and Note 9 – Benefit Plans of Notes to DP&L's Financial Statements for more information.


Contingent and Other Obligations
During the conduct of our business, we are subject to a number of federal and state laws and regulations, as well as other factors and conditions that potentially subject us to environmental, litigation, insurance and other risks. We periodically evaluate our exposure to such risks and record estimated liabilities for those matters where a loss is considered probable and reasonably estimable in accordance with GAAP. In recording such estimated liabilities, we may make assumptions, estimates and judgments that affect the reported amounts of assets, liabilities and expenses as they relate to contingent and other obligations. These assumptions and estimates are based on historical experience and assumptions and may be subject to change. We believe such estimates and assumptions are reasonable.

Table of Contents
Overview
We are subject to certain market risks including, but not limited to, changes in commodity prices for electricity and fluctuations in interest rates. We use various market risk-sensitive instruments, including derivative contracts, primarily to limit our exposure to fluctuations in interest rates. Our U.S. Risk Management Committee (U.S. RMC), comprised of members of senior management, is responsible for establishing risk management policies and the monitoring and reporting of risk exposures related to our operations. The U.S. 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

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 financial performance; and we may not be adequately hedged against our exposure to changes in interest rates.


Purchased power costs
DP&LAES Ohio conducts competitive bid auctions to purchase power for SSO service, as all of DP&L's AES Ohio's SSO is sourced through the competitive bid auction.


As a result of DPL's exit from the majority of its coal-fired generation, changes in the prices of fuel and purchased power are not expected to have a material impact on our results of operations, financial position or cash flows. Further, AES Ohio's exposure to fluctuations in the price of power is limited because we recover our power purchased from the competitive bid auction through the Standard Offer Rate tariff.


Interest rate risk
BecauseWe use long-term debt as a significant source of capital in our normal investingbusiness, which exposes us to interest rate risk. We do not enter into market risk sensitive instruments for trading purposes. We manage our exposure to interest rate risk through the use of fixed-rate debt and borrowing activities,by refinancing existing long-term debt at times when it is deemed economic and prudent. In regard to our financial results are exposedfixed rate debt, the interest rate risk with respect to fluctuationslong-term debt primarily relates to the potential impact a change in interest rates which we manage throughhas on the fair value of our regular financing activities. We maintain both cashfixed-rate debt and not on deposit and investments in cash equivalents that may be affected by adverse interest rate fluctuations. DPL and DP&L have both fixed-rate and variable rate long-term debt. On November 21, 2016, the DP&L $200.0 million variable-rate First Mortgage Bonds were hedged with floating for fixed interest rate swaps, reducingour financial condition or results of operations. Our interest rate risk exposure for the term of the bonds. On January 1, 2018 the interest rate on these First Mortgage Bonds was adjusted and as a result the bonds are no longer fully hedged and are treated as variable.our fixed-rate debt is associated with refinancing activity. Market indexes can be affected by market demand, supply, market interest rates and other economic conditions. See Note 76 – Long-term debt of Notes to DPL's Consolidated Financial Statements and Note 76 – Long-term debt of Notes to DP&L'sAES Ohio's Financial Statements.

At December 31, 2018,2021, our variable rate debt consisted of $65.0 million under DPL's revolving credit facility and $0.0 million under AES Ohio's revolving credit facility. At December 31, 2021, a 1%100-basis point change in interestthe applicable rates on our variable-rate debt would result in an approximately $14.9approximate $0.7 million change in DPL's interest expense and an approximately $5.9approximate $0.0 million change in DP&L'sAES Ohio's interest expense.

Equity price risk
At December 31, 2018,2021, approximately 33%42% of the defined benefit pension plan assets were comprised of investments in equity securities and 67%58% related to investments in fixed income securities, cash and cash equivalents and alternative investments. The equity securities are carried at their market value of approximately $105.2$151.8 million at December 31, 2018.2021. A hypothetical 10% decrease in prices quoted by stock exchanges would result in a $10.5$15.2 million reduction in fair value at December 31, 20182021 and approximately a $1.6$1.9 million increase to the 20192022 pension expense. See Note 8 – Benefit Plans of Notes to DPL's Consolidated Financial Statements and Note 8 – Benefit Plans of Notes to AES Ohio's Financial Statements for more information on our pension plans.


Credit risk
Credit risk is the risk of an obligor's failure to meet the terms of any investment contract, loan agreement or otherwise perform as agreed. Credit risk arises from all activities in which success depends on issuer, borrower or counterparty performance, whether reflected on or off the balance sheet. We limit our credit risk by assessing the creditworthiness of potential counterparties before entering into transactions with them and continue to evaluate their creditworthiness after transactions have been originated. We use the three leading corporate credit rating agencies and other current market-based qualitative and quantitative data to assess the financial strength of counterparties on an ongoing basis. We may require various forms of credit assurance from counterparties to mitigate credit risk.

Item 8 – Financial Statements and Supplementary Data
This report includes the combined filing of DPL and DP&L. Throughout this report, the terms “we,” “us,” “our” and “ours” are used to refer to both DPL and DP&L, respectively and altogether, unless the context indicates otherwise. Discussions or areas of this report that apply only to DPL or DP&L will clearly be noted in the section.

Report of Independent Registered Public Accounting Firm


To the Shareholder and Board of Directors of DPL Inc.


Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of DPL Inc. (the Company) as of December 31, 20182021 and 2017,2020, the related consolidated statements of operations, comprehensive income / (loss), shareholder’s deficit and cash flows and shareholder’s equity for each of the three years in the period ended December 31, 2018,2021, and the related notes and financial statement schedule listed in the Index at Item 15 (collectively referred to as the “financial“consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 20182021 and 2017,2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 20182021, in conformity with U.S. generally accepted accounting principles.


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


We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America.PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.



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

Regulatory Accounting
Description of the MatterAs described in Note 2 to the consolidated financial statements, the Company applies the provisions of FASC 980 “Regulated Operations,” which gives recognition to the ratemaking and accounting practices of the PUCO and the FERC. Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory liabilities generally represent obligations to provide refunds or future rate reductions to customers for previous overcollections or the deferral of revenues collected for costs that the Company expects to incur in the future. Accounting for the economics of rate regulation affects multiple financial statement line items, including property, plant, and equipment; regulatory assets and liabilities; revenues; and depreciation expense, and related disclosures in the Company’s consolidated financial statements.
Auditing the Company’s regulatory accounting was complex due to significant judgments made by management to support its assertions about the impact of future regulatory orders on the consolidated financial statements. In particular, there is subjectivity involved in assessing the impact of current and future regulatory orders on events that have occurred through December 31, 2021, judgment required to evaluate the relevance and reliability of audit evidence to support impacted account balances and disclosures, and judgments involved in assessing the probability of recovery in future rates of incurred costs or refunds to customers. These assumptions have a significant effect on the financial statements and related disclosures.
How We Addressed the Matter in Our AuditTo test the Company’s accounting for regulatory assets and liabilities, our audit procedures included, among others, reviewing relevant regulatory orders, statutes and interpretations; filings made by intervening parties; and other publicly available information, to assess the likelihood of recovery of regulatory assets in future rates or of a refund or future reduction in rates for regulatory liabilities based on precedents for the treatment of similar costs under similar circumstances. We evaluated the Company’s assertions regarding the probability of recovery of regulatory assets or refund or future reduction in rates for regulatory liabilities, to assess the Company’s assertion that amounts are probable of recovery or of a refund or future reduction in rates.

Note 1 – Overview and Summary of Significant Accounting Policies


Description of Business
DPL is a diversified regional energy company organized in 1985 under the laws of Ohio. DPL has one1 reportable segment, the Utility segment. See Note 1312 – Business Segments for more information relating to our reportable segment. The terms “we”, “us”, “our” and “ours” are used to refer to DPL and its subsidiaries.


On November 28, 2011, DPL was acquired by AES in the Merger and DPL became a wholly-owned subsidiary of AES. Following the merger of DPL and Dolphin Subsidiary II, Inc., DPL became an indirectly wholly-owned subsidiary of AES.


DP&L,AES Ohio, DPL's wholly-owned subsidiary, is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave consumers the right to choose the electric generation supplier from whom they purchase retail generation service,service; however, transmission and distributiondistribution services are still regulated. DP&LAES Ohio has the exclusive right to provide such service to its approximately525,000 534,000 customers located in West Central Ohio. 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. Since January 2016, DP&L has been sourcingAES Ohio sources all of the generation for its SSO customers through a competitive bid process. Through September 30, 2017, DP&LAES Ohio owned undivided interests inmultiple coal-fired power stations the retired Hutchings Coal Station until its transfer in 2020 and multiple peaking electric generating facilities as well ascurrently owns numerous transmission facilities. On October 1, 2017, the DP&L-owned generating facilities, excluding the Beckjord Facility and Hutchings EGU, were transferred to AES Ohio Generation, an affiliate of DP&L and wholly-owned subsidiary of DPL, through an asset contribution agreement to a subsidiary that was merged into AES Ohio Generation. Also, Stuart Station Unit 1 was retired on October 1, 2017. Principal industries located in DP&L’sAES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. DP&L'sAES Ohio's sales reflect the generalgeneral economic conditions, seasonal weather patterns of the area, and the market price of electricity. Through the dateelectricity and customer energy efficiency initiatives. AES Ohio also sells its proportional share of Generation Separation, DP&L sold energy and capacity from its investment in OVEC into the wholesale market.


DPL’s other primary subsidiaries includeare MVIC and AES Ohio Generation.Miami Valley Lighting. MVIC is our captive insurance company that provides insurance services to DPLAES Ohio and our subsidiaries.other subsidiaries, and Miami Valley Lighting provides street and outdoor lighting services to customers in the Dayton region. In prior periods, AES Ohio Generation owns an undivided interest in Conesville Unit 4. AES Ohio Generation sellswas also a primary subsidiary and sold all of its energy and capacity into the wholesale market. DPL's subsidiaries are wholly-owned.

On December 8, 2017, AES Ohio Generation completed the sale of the Miami Fort and Zimmer stations to subsidiaries of Dynegy in accordance with an asset purchase agreement dated April 21, 2017. In addition, on March 27, 2018, DPL and AES Ohio Generation completed the sale of their Peaker assets to Kimura Power, LLC. Further, on May 31, 2018, DPL and AES Ohio Generation retired the Stuart Station coal-firedits only remaining operating asset in May 2020 and diesel-fired generating units and the Killen Station coal-fired generating unit and combustion turbine, as planned.sold it in June 2020. See Note 1514 – Discontinued Operations for additional information.DPL's subsidiaries are wholly-owned.


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 or overcollections of riders.

DPL and its subsidiaries employed 659 people at January 31, 2019, of which 647 were employed by DP&L. Approximately 57% of all DPL employees are under a collective bargaining agreement.


Financial Statement Presentation
We prepare Consolidated Financial Statements for DPL. DPL’s Consolidated Financial Statements include the accounts of DPL and its wholly-owned subsidiaries except for DPL Capital Trust II which is not consolidated, consistent with the provisions of GAAP.

AES Ohio Generation's undivided ownership interests in certain coal-fired generating stations are included in the financial statements at amortized cost, net of subsequent impairments. Operating revenues and expenses are included on a pro rata basis in the corresponding lines in the Consolidated Statement of Operations.

Through June 2018, DP&L had undivided ownership interests in numerous transmission facilities. These undivided interests in jointly-owned facilities were accounted for on a pro rata basis in the Consolidated Financial Statements. In June 2018, DP&L closed on a transmission asset transaction with Duke and AEP, where ownership stakes in certain previously co-owned transmission assets were exchanged to eliminate co-ownership. Each previously co-owned transmission asset became wholly-owned by one of DP&L, Duke or AEP after the transaction. See Note 4 – Property, Plant and Equipment for more information.


All material intercompany accounts and transactions are eliminated in consolidation. We have evaluated subsequent events through the date this report is issued.


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


Use of Management Estimates
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: the carrying value of Property, plant and equipment; unbilled revenues; the valuation
61

Table of derivative instruments;Contents
revenues; the valuation of insurance and claims liabilities; the valuation of allowances for receivables and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; the valuation of AROs; and assets and liabilities related to employee benefits.


Cash and Cash Equivalents
Cash and cash equivalents are stated at cost, which approximates fair value. All highly liquid short-term investments with original maturities of three months or less are considered cash equivalents.

Restricted Cash
Restricted cash includes cash which is restricted as to withdrawal or usage. The restrictions relate to cash required for certain balance requirements.

The following table summarizes cash, cash equivalents and restricted cash amounts reported within the Consolidated Balance Sheets that reconcile to the total of such amounts as shown on the Consolidated Statements of Cash Flows:

The following table is a rollforward of our allowance for credit losses related to the accounts receivable balances for the years ended December 31, 2021 and 2020:
$ in millionsBeginning Allowance BalanceCurrent Period ProvisionWrite-offs Charged Against AllowancesRecoveries CollectedEnding Allowance Balance
2021$2.8 $(0.4)$(3.5)$1.4 $0.3 
2020$0.4 $3.0 $(2.3)$1.7 $2.8 

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 would impact collectability, as applicable, including the economic impacts of the COVID-19 pandemic on our receivable balance as of December 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 through September 1, 2020 due to the economic impacts of COVID-19. This order along with the economic impacts of COVID-19 has resulted in an increase in past due customer receivable balances in 2020, and thus the current period provision and the allowance for credit losses increased during the prior year. During 2021, the current period provision and allowance for credit losses decreased due to lower past due customer receivable balances. See Note 16 – Risks & Uncertainties for additional discussion of the COVID-19 pandemic. As discussed in Note 2 – Regulatory Matters, AES Ohio’s uncollectible expense is deferred for future collection.

Inventories
Inventories are carried at average cost, net of reserves, and include materials and supplies used for utility operations.

Regulatory Accounting
As a regulated utility, AES Ohio applies the provisions of FASC 980 “Regulated Operations”, which gives recognition to the ratemaking and accounting practices of the PUCO and the FERC. Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory assets have been included as allowable costs for ratemaking purposes, as authorized by the PUCO or established regulatory practices. Regulatory liabilities generally represent obligations to make refunds or future rate reductions to customers for previous over collections or the deferral of revenues collected for costs that AES Ohio expects to incur in the future.

The deferral of costs (as regulatory assets) is appropriate only when the future recovery of such costs is probable. In assessing probability, we consider such factors as specific orders from the PUCO or the FERC, regulatory precedent and the current regulatory environment. To the extent recovery of costs is no longer deemed probable, related regulatory assets would be required to be expensed in current period earnings. Our regulatory assets and liabilities have been created pursuant to a specific order of the PUCO or the FERC or established regulatory practices, such as other utilities under the jurisdiction of the PUCO or the FERC being granted recovery of similar costs. It is probable, but not certain, that these regulatory assets will be recoverable, subject to approval by the PUCO or the FERC. Regulatory assets and liabilities are classified as current or non-current based on the term in which recovery is expected. See Note 2 – Regulatory Matters for more information.

Property, Plant and Equipment
New property, plant and equipment additions are stated at cost. For regulated transmission and distribution property, cost includes direct labor and material, allocable overhead expenses and an allowance for funds used during construction (AFUDC). AFUDC represents the cost of borrowed funds and equity used to finance regulated construction projects. Capitalization of AFUDC and interest ceases at either project completion or at the date specified by regulators. AFUDC and capitalized interest was $3.7 million, $3.0 million and $3.2 million in the years ended December 31, 2021, 2020 and 2019, respectively.

For substantially all depreciable property, when a unit of property is retired, the original cost of that property less any salvage value is charged to Accumulated depreciation and amortization, consistent with composite depreciation practices.

Impairment of Long-lived Assets
GAAP requires that we test long-lived assets for impairment when indicators of impairment exist. If an asset is deemed to be impaired, we are required to write down the asset to its fair value with a charge to current earnings. The net book value of our property, plant, and equipment was $1,700.8 million and $1,565.3 million as of December 31, 2021 and 2020, respectively. We do not believe any of these assets are currently impaired. In making this assessment, we consider such factors as: the overall condition and distribution capacity of the assets; the expected ability to recover additional expenditures in the assets; and the anticipated demand and relative pricing of retail electricity in our service territory.

Depreciation
Depreciation expense is calculated using the straight-line method, which allocates the cost of property over its estimated useful life. For DPL’s transmission and distribution assets, straight-line depreciation is applied monthly on an average composite basis using group rates that approximated 3.7% in 2021, 3.8% in 2020 and 4.0% in 2019. Depreciation expense was $72.9 million, $70.0 million and $67.9 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Intangibles
Intangibles include software and renewable energy credits. Renewable energy credits are carried on a weighted average cost basis and amortized as they are used or retired.

Software is amortized over seven years. Amortization expense was $3.2 million, $3.3 million and $4.4 million for the years ended December 31, 2021, 2020 and 2019, respectively. The estimated amortization expense of this internal-
63

Table of Contents
use software over the next five years is $9.9 million ($2.8 million in 2022, $2.1 million in 2023, $1.9 million in 2024, $1.6 million in 2025 and $1.5 million in 2026).

Implementation Costs Related to Software as a Service
DPL has recorded prepayments for implementation costs related to software as a service in support of utility customer services of $8.0 million and $4.1 million as of December 31, 2021 and 2020, respectively, and these are recorded within Other Non-current Assets on the accompanying Consolidated Balance Sheets.

Debt Issuance Costs
Costs incurred in connection with the issuance of long-term debt are deferred and presented as a direct reduction from the face amount of that debt and amortized over the related financing period using the effective interest method. Debt issuance costs related to a line-of-credit or revolving credit facility are deferred and presented as an asset and amortized over the related financing period. Make-whole payments in connection with early debt retirements are classified as cash flows used in financing activities.

Financial Instruments
Our Master Trust investments in debt and equity financial instruments of publicly traded entities are classified as equity investments. These equity securities are carried at fair value and unrealized gains and losses on these securities are recorded in Other income. As these financial instruments are held to be used for the benefit of employees or former employees participating in employee benefit plans and are not used for general operating purposes, they are classified as non-current in Other non-current assets on the Consolidated Balance Sheets. See
Note 4 – Fair Value for additional information.

Financial Derivatives
We have contracts involving the physical delivery of energy. Because these contracts qualify for the normal purchases and normal sales scope exception in ASC 815, we have elected to account for them as accrual contracts, which are not adjusted for changes in fair value.

We have, in the past, used interest rate hedges to manage the interest rate risk of our variable rate debt. We used cash flow hedge accounting when the hedge or a portion of the hedge was deemed to be highly effective, which resulted in changes in fair value being recorded within accumulated other comprehensive loss, a component of shareholder’s deficit. We elected not to offset net derivative positions in the financial statements. Accordingly, we did not offset such derivative positions against the fair value of amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral under master netting agreements. See Note 5 – Derivative Instruments and Hedging Activities for additional information.

Insurance and Claims Costs
In addition to insurance obtained from third-party providers, MVIC, a wholly-owned captive subsidiary of DPL, provides insurance coverage solely to us and our subsidiaries for workers’ compensation, general liability and property damage on an ongoing basis. Insurance and claims costs associated with MVIC include estimated liabilities of approximately $2.3 million and $3.2 million at December 31, 2021 and 2020, respectively, within Accrued and other current liabilities on the DPL Consolidated Balance Sheets. DPL has estimated liabilities for medical, life, disability and other reserves for claims costs below certain coverage thresholds of third-party providers of approximately $9.7 million and $11.1 million at December 31, 2021 and 2020, respectively, within Accrued and other current liabilities and Other non-current liabilities on the balance sheets. The estimated liabilities for workers’ compensation, medical, life and disability costs at DPL are actuarially determined using certain assumptions. There is uncertainty associated with these loss estimates, and actual results may differ from the estimates. Modification of these loss estimates based on experience and changed circumstances is reflected in the period in which the estimate is re-evaluated.

Revenue Recognition
Revenues are recognized from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Energy sales to customers are based on the reading of their meters that occurs on a systematic basis throughout the month. We recognize the revenues on our Consolidated Statements of Operations using an accrual method for retail and other energy sales that have not yet been billed, but where electricity has been consumed. This is termed “unbilled revenues” and is a widely recognized and accepted practice for utilities. At the end of each month, unbilled revenues are determined by the estimation of unbilled energy provided to customers since the date of the last meter reading, estimated line losses, the assignment of unbilled energy provided to customer classes and the average rate per customer class.

The power sales and purchases within DP&L’s service territory are reported on a net hourly basis as revenues or purchased power on our Consolidated Statements of Operations. We record expenses when purchased electricity is received and when expenses are incurred. All of the power produced at the generation station is sold to an RTO. We record expenses when purchased electricity is received and when expenses are incurred. For additional information, see Note 1413 – Revenue.


AllowanceAccounting for Uncollectible AccountsTaxes Collected from Customers and Remitted to Governmental Authorities
We establish provisionsAES Ohio collects certain excise taxes levied by state or local governments from its customers. AES Ohio’s excise taxes and certain other taxes are accounted for uncollectible accounts by using both historical average loss percentages to project future losseson a net basis and by establishing specific provisions for known credit issues. Amounts are written off when reasonable collections efforts have been exhausted.

Property, Plant and Equipment
We record our ownership share of our undivided interestrecorded as a reduction in our jointly-held station as an asset in property, plant and equipment. New property, plant and equipment additions are stated at cost. For regulated transmission and distribution property, cost includes direct labor and material, allocable overhead expenses and an allowance for funds used during construction (AFUDC). AFUDC represents the cost of borrowed funds and equity used to finance regulated construction projects. For non-regulated property, cost also includes capitalized interest. Capitalization of AFUDC and interest ceases at either project completion or at the date specified by regulators. AFUDC and capitalized interest was $0.5 million, $1.7 million and $2.1 millionrevenues in the years ended December 31, 2018, 2017 and 2016, respectively.accompanying Consolidated Statements of Operations. The amounts of such taxes were as follows:

Years ended December 31,
$ in millions202120202019
Excise taxes collected$48.7 $48.1 $50.1 

For unregulated generation property, cost includes direct labor and material, allocable overhead expenses and interest capitalized during construction per the provisions of GAAP related to the accounting for capitalized interest.

For substantially all depreciable property, when a unit of property is retired, the original cost of that property less any salvage value is charged to Accumulated depreciation and amortization, consistent with composite depreciation practices.

Property is evaluated for impairment when events or changes in circumstances indicate that its carrying amount may not be recoverable.


Repairs and Maintenance
Costs associated with maintenance activities are recognized at the time the work is performed. These costs, which include labor, materials and supplies and outside services required to maintain equipment and facilities, are capitalized or expensed based on defined units of property.

Depreciation
Depreciation expense is calculated usingPension and Postretirement Benefits
We recognize in our Consolidated Balance Sheets an asset or liability reflecting the straight-line method,funded status of pension and other postretirement plans with current-year changes from actuarial gains or losses related to our regulated operations, that would otherwise be recognized in AOCL, recorded as a regulatory asset as this can be recovered through future rates. Such changes that are not related to our regulated operations are recognized in AOCL. All plan assets are recorded at fair value. We follow the measurement date provisions of the accounting guidance, which allocates the costrequire a year-end measurement date of property over its estimated useful life. For DPL’s generation, transmissionplan assets and distribution assets, straight-line depreciation is applied monthly on an average composite basis using group rates that approximated 4.3%obligations for all defined benefit plans.

We account for and disclose pension and postretirement benefits in 2018, 5.0% in 2017 and 6.1% in 2016 (including property classified in non-current assets of discontinued operations and held-for-sale businesses in 2017 and 2016). Depreciation expense was $66.5 million, $70.4 million and $67.0 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Regulatory Accounting
As a regulated utility, DP&L appliesaccordance with the provisions of FASC 980 “Regulated Operations”, which gives recognitionGAAP relating to the ratemakingaccounting for pension and accounting practicesother postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the PUCOplans. Consistent with the requirements of FASC 715, we apply a disaggregated discount rate approach for determining service cost and the FERC. Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory assets have been included as allowable costsinterest cost for ratemaking purposes, as authorized by the PUCO or established regulatory practices. Regulatory liabilities generally represent obligations to make refunds or future rate reductions to customers for previous over collections or the deferral of revenues collected for costs that DP&L expects to incur in the future.our defined benefit pension plans and postretirement plans.


The deferral of costs (as regulatory assets) is appropriate only when the future recovery of such costs is probable. In assessing probability, we consider such factors as specific orders from the PUCO or FERC, regulatory precedent and the current regulatory environment. To the extent recovery of costs is no longer deemed probable, related regulatory assets would be required to be expensed in current period earnings. Our regulatory assets and liabilities have been created pursuant to a specific order of the PUCO or FERC or established regulatory practices, such as other utilities under the jurisdiction of the PUCO or FERC being granted recovery of similar costs. It is probable, but not certain, that these regulatory assets will be recoverable, subject to PUCO or FERC approval. Regulatory assets and liabilities are classified as current or non-current based on the term in which recovery is expected. See Note 38Regulatory MattersBenefit Plans for more information.

Inventories
Inventories are carried at average cost, net of reserves, and include coal, limestone and materials and supplies used for utility operations.

Intangibles
Intangibles include software, emission allowances and renewable energy credits. Emission allowances are carried on a first-in, first-out (FIFO) basis for purchased emission allowances. Net gains or losses on the sale of excess emission allowances, representing the difference between the sales proceeds and the cost of emission allowances, are recorded as a component of our fuel costs and are reflected in Operating income when realized. Emission allowances are amortized as they are used in our operations on a FIFO basis. Renewable energy credits are carried on a weighted average cost basis and amortized as they are used or retired.

Software is amortized over seven years. Amortization expense was $6.6 million, $5.7 million and $6.6 million for the years ended December 31, 2018, 2017 and 2016, respectively. The estimated amortization expense of this internal-use software over the next five years is $15.0 million ($4.2 million in 2019, $3.2 million in 2020, $3.0 million in 2021, $2.6 million in 2022 and $2.0 million in 2023).


Income Taxes
Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of the existing assets and liabilities and their respective income tax bases. We establish an allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. Our tax positions are evaluated under a more likely than not recognition threshold and measurement analysis before they are recognized for financial statement reporting. Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid within one year. Our policy for interest and penalties is to recognize interest and penalties as a component of the provision for income taxes in the Consolidated Statement of Operations.


Income taxes payable, which are includable in allowable costs for ratemaking purposes in future years, are recorded as regulatory assets or liabilityliabilities with a corresponding deferred tax liability or asset. Investment tax credits that reduced federal income taxes in the years they arose have been deferred and are being amortized to income over the useful lives of the properties in accordance with regulatory treatment. See Note 32 – Regulatory Matters for additional information.


DPL and its subsidiaries file U.S. federal income tax returns as part of the consolidated U.S. income tax return filed by AES. The consolidated tax liability is allocated to each subsidiary based on the separate return method which is specified in our tax allocation agreement and which provides a consistent, systematic and rational approach. See Note 87 – Income Taxes for additional information.


Related Party Transactions
In the normal course of business, DPL enters into transactions with related parties. All material intercompany accounts and transactions are eliminated in DPL’s Consolidated Financial InstrumentsStatements. See Note 11 – Related Party Transactions for more information on Related Party Transactions.
Our Master
DPL Capital Trust investments in debt and equity financial instruments of publicly traded entities are classified as equity investments. These equity securities are carried at fair value and unrealized gains and losses on these securities are recorded in Other income. As these financial instruments are held to be usedII
DPL has a wholly-owned business trust, DPL Capital Trust II (the Trust), formed for the benefitpurpose of employees participatingissuing trust capital securities to third-party investors. In 2003, DPL deconsolidated the Trust upon adoption of the accounting standards related to variable interest entities and currently treats the Trust as an unconsolidated subsidiary. The Trust holds mandatorily redeemable trust capital securities. The investment in employee benefit plansthe Trust, which amounts to $0.2 million and are not used for general operating purposes, they are classified as non-current in$0.2 million at December 31, 2021 and 2020, respectively, is included within Other deferrednoncurrent assets on the Consolidated Balance Sheets.consolidated balance sheets.

Table of long-lived assets until the completion of the sale, at which point, any additional loss is recognized. If the fair value of the business subsequently exceeds the carrying amount while the business is still held-for-sale, any impairment expense previously recognized will be reversed up to the lower of the previously recognized expense or the subsequent excess.Contents

Assets and liabilities related to a business classified as held-for-sale are segregated in the current balance sheet in the period in which the business is classified as held-for-sale. Assets and liabilities of held-for-sale businesses are classified as current when they are expected to be disposed of within twelve months. Transactions between the business held-for-sale and businesses that are expected to continue to exist after the disposal are not eliminated to appropriately reflect the continuing operations and balances held-for-sale. See Note 15 – Discontinued Operations for further information.

Discontinued Operations
Discontinued operations reporting occurs only when the disposal of a business or a group of assets represents a strategic shift that has (or will have) a major effect on our operations and financial results. We report financial results for discontinued operations separately from continuing operations to distinguish the financial impact of disposal transactions from ongoing operations. Prior period amounts in the statement of operations and balance sheetsheets are retrospectively revised to reflect the businesses determined to be discontinued operations. The cash flows of businesses that are determined to be discontinued operations are included within the relevant categories within operating, investing and financing activities on the face of the Consolidated Statements of Cash Flows.


Transactions between the businesses determined to be discontinued operations and businesses that are expected to continue to exist after the disposal are not eliminated to appropriately reflect the continuing operations and balances held-for-sale. The results of discontinued operations include any gain or loss recognized on closing or adjustment of the carrying amount to fair value. See Note 1514 – Discontinued Operations for further information.


Accounting for Taxes Collected from Customers and Remitted to Governmental Authorities
DP&L collects certain excise taxes levied by state or local governments from its customers. DP&L’s excise taxes and certain other taxes are accounted for on a net basis and recorded as a reduction in revenues in the accompanying Consolidated Statements of Operations. The amounts for the years ended December 31, 2018, 2017 and 2016, were $51.7 million, $49.4 million and $50.9 million, respectively.

Cash and Cash Equivalents
Cash and cash equivalents are stated at cost, which approximates fair value. All highly liquid short-term investments with original maturities of three months or less are considered cash equivalents.

Restricted Cash
Restricted cash includes cash which is restricted as to withdrawal or usage. The nature of the restrictions includes restrictions imposed by agreements related to deposits held as collateral and cash collected under the DMR which is restricted to pay debt obligations at DPL and DP&L and position DP&L to modernize and/or maintain its transmission and distribution infrastructure.

The following table provides a summary of cash, cash equivalents, and restricted cash amounts reported on the Consolidated Balance Sheet that reconcile to the total of such amounts as shown on the Consolidated Statements of Cash Flows:
$ in millions December 31, 2018 December 31, 2017

Financial Derivatives
All derivatives are recognized as either assets or liabilities in the balance sheets and are measured at fair value. Changes in the fair value are recorded in earnings unless the derivative is designated as a cash flow hedge of a forecasted transaction or it qualifies for the normal purchases and sales exception.

We use interest rate hedges to manage the interest rate risk of our variable rate debt. We use cash flow hedge accounting when the hedge or a portion of the hedge is deemed to be highly effective, which results in changes in fair value being recorded within accumulated other comprehensive income, a component of shareholder’s equity. We have elected not to offset net derivative positions in the financial statements. Accordingly, we do not offset such derivative positions against the fair value of amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral under master netting agreements. See Note 6 – Derivative Instruments and Hedging Activities for additional information.

Insurance and Claims Costs
In addition to insurance obtained from third-party providers, MVIC, a wholly-owned captive subsidiary of DPL, provides insurance coverage solely to us and our subsidiaries for workers’ compensation, general liability, and property damage on an ongoing basis. Insurance and Claims Costs on DPL’s Consolidated Balance Sheets associated with MVIC include estimated liabilities of approximately $4.1 million and $3.0 million at December 31, 2018 and 2017, respectively. DPL has estimated liabilities for medical, life, disability, and other reserves for claims costs below certain coverage thresholds of third-party providers of approximately $4.3 million and $4.4 million at December 31, 2018 and 2017, respectively, within Other current liabilities and Other deferred credits on the balance sheets. The estimated liabilities for workers’ compensation, medical, life and disability costs at DPL are actuarially determined using certain assumptions. There is uncertainty associated with these loss estimates, and actual results may differ from the estimates. Modification of these loss estimates based on experience and changed circumstances is reflected in the period in which the estimate is re-evaluated.

Pension and Postretirement Benefits
We recognize in our Consolidated Balance Sheets an asset or liability reflecting the funded status of pension and other postretirement plans with current-year changes from actuarial gains or losses related to our regulated operations, that would otherwise be recognized in AOCI, recorded as a regulatory asset as this can be recovered through future rates. Such changes that are not related to our regulated operations are recognized in AOCI. All plan assets are recorded at fair value. We follow the measurement date provisions of the accounting guidance, which require a year-end measurement date of plan assets and obligations for all defined benefit plans.


We account for and disclose pension and postretirement benefits in accordance with the provisions of GAAP relating to the accounting for pension and other postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the plans. Consistent with the requirements of FASC 715, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans.

2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit CostThis standard changes the presentation of non-service costs associated with defined benefit plans and updates the guidance so that only the service cost component will be eligible for capitalization.
Transition method: retrospective for presentation of non-service cost and prospective for the change in capitalization.
January 1, 2018For the years ended December 31, 2017 and 2016 we reclassified non-service pension costs from Operating expenses to Other expense of $2.2 million and $3.2 million, respectively.
2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)This standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows.
Transition method: retrospective.
January 1, 2018For the years ended December 31, 2017 and 2016, we reclassified from "Net cash used in investing activities" to "Net increase / (decrease) in cash, cash equivalents and restricted cash" $27.1 million and ($11.8) million, respectively.

It also amends certain disclosures of financial instruments.
Transition method: modified retrospective. Prospective for equity investments without readily determinable fair value.
January 1, 2018We adopted this standard January 1, 2018. At that date, we transferred $1.6 million ($1.0 million net of tax) of unrealized gains from AOCI to Accumulated Deficit.

Adoption of FASC Topic 606, "Revenue from Contracts with Customers"326, "Financial Instruments - Credit Losses"
On January 1, 2018,2020, we adopted ASU 2014-09, "Revenue from Contracts with Customers",ASC 326 Financial Instruments - Credit Losses and its subsequent corresponding updates ("FASC 606"ASC 326"). The core principlenew 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 this standard isan 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 entity shall recognize revenueallowance on the balance sheet with a corresponding adjustment to depictearnings in the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. income statement.

We applied the modified retrospective method of adoption to those contracts which were not completed asfor ASC 326. Under this transition method, we applied the transition provisions starting at the date of January 1, 2018. Results for reporting periods beginning January 1, 2018 are presented under FASC 606, while prior period amounts were not adjusted and continue to be reportedadoption. The CECL model primarily impacts the calculation of our expected credit losses in accordance with our historic accounting under the previous revenue recognition standard. For contracts that were modified before January 1, 2018, we have not retrospectively restated the contracts for modifications. We instead reflected the aggregate effect of all modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price. We do not expect thegross customer trade accounts receivable. The adoption of ASC 326 and the new revenue standard toapplication of CECL on our trade accounts receivable did not have a material impact toon our net income on an ongoing basis.Consolidated Financial Statements.

(a)ASU 2016-01 “Recognition and Measurement of Financial Assets and Financial Liabilities” was effective as of January 1, 2018. This ASU requires the change in the fair value of equity instruments to be recorded in income rather than in OCI. Equity Instruments were defined to include all mutual funds, regardless of the underlying investments. Therefore, as of January 1, 2018, AOCI of $1.6 million ($1.0 million net of tax) was reversed to Accumulated Deficit.

Distribution Rate OrderAES Ohio ESP and SEET Proceedings, Comprehensive Settlement
On September 26, 2018 the PUCO issued the DRO establishing new base distribution rates for DP&L, which became effective OctoberOhio law requires utilities to file either an ESP or MRO plan to establish SSO rates. From November 1, 2018. The DRO2017 through December 18, 2019, AES Ohio operated pursuant to an approved without modification, a stipulation and recommendation

previously filed by DP&L, along with various intervening parties and the PUCO staff. The DRO established a revenue requirement of $248.0 million for DP&L's electric service base distribution rates which reflects an increase to distribution revenues of approximately $29.8 million per year. In addition to the increase in base distribution rates, and among other matters, the DRO provides for a return on equity of 9.999% and a cost of long-term debt of 4.8% and for the following items:

DIR– The DRO authorized DP&L to begin charging a Distribution Investment Rider ("DIR") set initially at $12.2 million annually, effective October 1, 2018. The DIR revenue requirement shall be updated quarterly and will increase as DP&L makes qualified investments in its distribution network, subject to annual revenue limits which increase each year; the revenue limit for 2019 is $22.0 million. The DIR will expire in November 2022 unless DP&L files a base distribution rate case on or before October 31, 2022, in which case the DIR will expire in November 2023.

Decoupling Rider – The DRO eliminated provisions in the existing decoupling rider which allowed DP&L to recover lost revenues resulting from the implementation of energy efficiency programs and replaced it with a revenue requirement that attempts to eliminate the impacts of weather and demand on DP&L’s revenues from residential and commercial distribution customers beginning January 1, 2019. As a result, in years with very mild weather and/or decreased demand, DP&L will be able to accrue a regulatory asset for recovery through the rider to normalize the revenues. Conversely, in periods of extreme temperatures or high demand for electricity, DP&L may record a liability for future reimbursement to customers. The rider also includes a one-time $3.7 million revenue requirement based on the increase in the number of DP&L’s residential and commercial customers from the rate case test year until September 30, 2018. Such amount was accrued and included in revenues in the third quarter of 2018 and will be collected by DP&L in 2019.

TCJA – The DRO partially resolved the TCJA impacts. The new distribution rates include the impacts of the decrease in current federal income taxes beginning October 1, 2018. The DRO did not designate how much DP&L may owe for any overcollection of taxes from January 1, 2018 through September 30, 2018, nor did it resolve any decrease in future rates related to amortization of excess accumulated deferred income taxes (“ADIT”). The DRO did, however, stipulate that DP&L must refund its customers an amount no less than $4.0 million per year for the first five years of the amortization period unless all balances owed are fully returned within the first five years. For more on the impacts of the TCJA, see below.

Vegetation Management Costs – The DRO authorizes DP&L to defer as a regulatory asset, with no carrying costs, annual expenses for vegetation management performed by third-party vendors. For calendar year 2018 annual expenses which are incremental to the baseline of $10.7 million can be deferred up to a $4.6 million cap. For calendar years 2019 and thereafter, annual expenses in excess of $15.7 million can be deferred up to a $4.6 million annual cap. Annual spending of less than the vegetation management baseline amounts will result in a reduction to the regulatory asset or creation of a regulatory liability. For 2018, DP&L accrued a regulatory asset for the maximum amount of $4.6 million based upon such provisions and spending above the baseline.

In December 2018, DP&L filed a Distribution Modernization Plan (“DMP”) with the PUCO proposing to invest $576.0 million in capital projects over the next 10 years. There are eight principal components of DP&L’s DMP: 1) Smart Meters, 2) Self-Healing Grid, 3) Customer Engagement, 4) Enhancing Sustainability and Embracing Innovation. 5) Telecommunications, 6) Physical and Cyber Security, 7) Governance and Analytics, and 8) Grid Modernization R&D.

ESP Order
On March 13, 2017, DP&L filed an amended stipulation to its 2017 ESP,plan, which was subject to approval by the PUCO. A final decision was issued by the PUCOinitially approved on October 20, 2017 modifying(ESP 3). On December 18, 2019, the PUCO approved AES Ohio's Notice of Withdrawal and adoptingreversion to its prior rate plan (ESP 1). Among other items, the amended stipulationPUCO Order approving the ESP 1 rate plan includes:

Reinstating the non-bypassable RSC Rider, which provides annual revenues of approximately $79.0 million;
Continuation of AES Ohio's Transmission Cost Recovery Rider, Storm Rider and recommendation. The six-year 2017 ESP establishes DP&L's framework for providing retail service on a going-forward basis including rate structures, non-bypassable charges and other specific rate recovery true-up mechanisms which include, but are not limited to, the following:
Bypassablebypassable standard offer energy ratesrate for DP&L’sAES Ohio's customers based on competitive bid auctions;
and
A placeholder rider to recover grid modernization costs, called the Infrastructure Investment Rider.
The establishment
Separate from the ESP process, AES Ohio filed a petition seeking recovery of ongoing OVEC costs through a three-year non-bypassable Distribution ModernizationLegacy Generation Rider (DMR) designedand was granted approval effective January 1, 2020.

On October 23, 2020, AES Ohio entered into a Stipulation and Recommendation (the Settlement) with the staff of the PUCO and various customers, and organizations representing customers of AES Ohio and certain other parties with respect to, collect $105.0 million in revenue per year to pay debt obligationsamong other matters, AES Ohio's applications pending at DPL and DP&L and position DP&Lthe PUCO for (i) approval of AES Ohio's plan to modernize and/or maintain its transmissiondistribution grid (the Smart Grid Plan), (ii) findings that DP&L passed the SEET for 2018 and distribution infrastructure with an option2019, and (iii) findings that AES Ohio's current ESP 1 satisfies the SEET and the more favorable in the aggregate (MFA) regulatory test. A hearing was held in January 2021 for DP&L to fileconsideration of this settlement and on June 16, 2021, the PUCO issued their opinion and order accepting the stipulation as filed. Several applications for

an extension rehearing of the riderPUCO's orders relating to the Settlement were filed and denied on December 1, 2021. The OCC appealed this final PUCO Order to the Ohio Supreme Court on December 6, 2021; this appeal remains pending.

The settlement provides, among other items, for an additional two yearsthe following:

Approval of the Smart Grid Plan outlined in an amountthe Smart Grid Plan application filed by AES Ohio with the PUCO, as modified by the terms of the settlement, including, subject to approval by the PUCO. Consistent with that settlementoffsetting operational benefits and the PUCO order,certain other conditions, a return on January 22, 2019, DP&L filed a requestand recovery of up to extend the DMR for the additional two years at an annual revenue amount$249.0 million of $199.0 million. That request is pending PUCO review;
The establishmentSmart Grid Plan Phase 1 capital investments and recovery of a non-bypassable Distributionoperational and maintenance expenses through AES Ohio's existing Infrastructure Investment Rider to recover incremental distribution capital investments,for a term of four years, under an aggregate cap of $267.6 million on the amount of such investments and expenses that is recoverable, and an acknowledgement that AES Ohio may file a subsequent application with the PUCO within three years seeking approvals for Phase 2 of the Smart Grid Plan;
A commitment by AES Ohio to invest in a customer information system and supporting technologies during Phase 1 of the Smart Grid Plan, with AES Ohio recovering a return on and of prudently incurred capital investments and operational and maintenance expenses, including deferred operational and maintenance expense amounts, in a future rate case;
Determinations that AES Ohio’s ESP 1 satisfies the prospective SEET and the MFA regulatory test and that AES Ohio satisfies the retroactive SEET for 2018 and 2019.
A commitment by AES Ohio to file an application with the PUCO no later than October 1, 2023 for a new electric security plan that does not seek to implement certain non-bypassable charges, including those related to provider of last resort risks, stability, or financial integrity; and
AES Ohio shareholder funding, in an aggregate amount of approximately $30.0 million over four years, for certain economic development discounts, incentives, and grants to certain commercial and industrial customers, including hospitals and manufacturers, assistance for low-income customers as well as the residents and businesses of the City of Dayton, and promotion of solar and resiliency development within AES Ohio's service territory.

Certain parties which was establishedintervened in the DP&L DRO;
A non-bypassable Reconciliation Rider permitting DP&LESP proceedings have filed petitions for rehearing of the recent PUCO ESP orders; some of which seek to defer, recover or credit the net proceeds from selling energy and capacity received as part of DP&L’s investment in OVEC and DP&L's OVEC related costs;
Implementation by DP&L of a Smart Grid Rider, Economic Development Rider, Economic Development Fund, Regulatory Compliance Rider and certain other new, or changes to existing, rates, riders and competitive retail market enhancements, with tariffs consistent with the order. These riders became effective November 1, 2017;
A commitment to commence a sale process to sell our ownership interests in the Miami Fort, Zimmer and Conesville coal-fired generation plants, with all sales proceeds used to pay debt of DPL and DP&L;
Restrictions on DPL making dividend or tax sharing payments and an obligation to convert then existing tax payments owed by DPL to eliminate AES into equity investments in DPL. See Note 8 – Income Taxes and Note 10 – Equity for more information on the tax sharing payment restrictions; and
Various other riders and competitive retail market enhancements.

On October 19, 2018 IGS, a retail electricity supplier, filed a Notice of WithdrawalOhio's RSC from the amended settlement, citing a material modification byESP 1 rates that are currently in place and others seek to re-implement ESP 3, but without the PUCO's October 2017 order. To addressDMR. We are unable to predict the withdrawal, the PUCO established a new procedural schedule, including a hearing currently scheduled to begin April 1, 2019. Additionally, on January 7, 2019, the Ohio Consumers' Counsel appealed the 2017outcomes of these petitions, but if these result in terms that are more adverse than AES Ohio's current ESP Order to the Supreme Court of Ohio. That appeal is pending.

DP&L is subject to a SEET threshold and is required to apply general rules for calculating earnings and comparing them to a comparable group to determine whether there were significantly excessive earnings during a given calendar year. The 2017 ESP maintains DP&L’s return on equity SEET threshold at 12% and provides that DMR amounts are excluded from the SEET calculation. On October 22, 2018, a stipulation was reached agreeing that DP&L did not exceed the SEET threshold for 2016 or 2017. That stipulation is pending PUCO approval. In future years, the SEETrate plan, it could have a material adverse effect on our results of operations, financial condition and cash flows.

Table of Tax ReformContents
Consistent with AES' earlier statement of intent, with the PUCO's issuance of their opinion and order, during 2021 DPL received $150.0 million from AES and, in turn, DPL made a capital contribution of $150.0 million to AES Ohio to enable AES Ohio to seek to improve its infrastructure and modernize its grid while maintaining liquidity.

Decoupling
On January 10, 201823, 2021 AES Ohio filed with the PUCO initiated a proceedingrequesting approval to considerdefer its decoupling costs consistent with the methodology approved in its Distribution Rate Case. An evidentiary hearing was held in May 2021. 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.

COVID-19
In response to the TCJAPUCO’s COVID-19 emergency orders, AES Ohio filed an Application on March 23, 2020, requesting waivers of certain rule and tariff requirements and deferral of certain costs and revenues including those related to determinedeposits 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 appropriate coursePUCO approved the application and required AES Ohio to file a plan outlining the timing and steps it plans to take in an effort to return to normal operations. The authorized deferral of action to pass benefits resulting fromthose certain costs and revenues must be offset by COVID-19 related savings. AES Ohio filed its plan on July 15, 2020 and was approved by the legislationPUCO on to ratepayers. The PUCO also directedAugust 12, 2020. As a result, AES Ohio utilities to record deferred liabilities for the estimated reduction has recorded a $0.9 million and $1.2 million regulatory asset as of December 31, 2021 and 2020, respectively. Recovery of these deferrals will be addressed in federal income tax resulting from the TCJA beginning January 1, 2018. Under the terms of the ESP, DPL will not make tax sharing payments. Under the terms of the stipulation in thea future rate proceeding.

Distribution Rate Case
On November 30, 2020, AES Ohio filed a new distribution rate case mentioned above, DP&L agreed to file an application atwith the PUCOPUCO. 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 March 1, 2019 to refund eligible excess accumulated deferred income taxes (ADIT)the tornados that occurred on Memorial Day in 2019. The rate case also includes a proposal for increased tree-trimming expenses and any relatedcertain customer demand-side management programs and recovery of prior-approved regulatory liability overassets for tree trimming, uncollectible expenses and rate case expense. A hearing on this case was held in January 2022, and the case is pending a 10-year period. Excess ADIT related to depreciation life and method differences will be returned to customers in accordance with federal tax law and related regulations. DP&L’s rates were set using the new tax rate as a result of the distribution rate case.commission order.


FERC Proceedings
On May 8, 2018, DP&LMarch 3, 2020, AES Ohio filed an application before the FERC seeking to adjustchange its FERC jurisdictionalexisting stated transmission rates to reflectformula transmission rates that would be updated each calendar year. This filing was approved and made effective as of May 3, 2020, subject to possible refunds if the effectsapproved rates were modified. An uncontested settlement was filed December 10, 2020 and approved April 15, 2021. Among other things, the settlement established new depreciation rates for AES Ohio’s transmission assets and an authorized return on equity of 9.85%, and started an amortization process to return excess deferred taxes created by the TCJA. Because the approved settlement rates were lower than the proposed rates that went into effect, AES Ohio has accrued and/or paid refunds of approximately $4.4 million to users of the decrease in federal income tax ratestransmission system through December 31, 2021 through credits on the current portion of income tax expense as part of the TCJA, resulting in a decrease of approximately $2.4 million annually. The revised rates are in effect and all DP&L over and undercollections dating backPJM bills. Pursuant to the March 21stapproved mechanisms and formula, transmission rates were adjusted, effective date were settledon January 1, 2022, to reflect projected 2022 costs, adjusted to true-up the projections of revenues and costs incurred during 2020. Adjustments to true-up 2021 revenues and costs will be reflected in December 2018.

On November 15, 2018 FERC issued a Notice of Proposed Rulemaking to address amortization of excess accumulated deferred income taxes resulting from the TCJA and their impact on2023 formula transmission rates. Such notice requires all public utility transmission providersAt December 31, 2021, AES Ohio has recorded a liability of $12.6 million, with stated transmission rates under an Open Access Transmission Tariff (OATT)$0.4 million classified as current, representing credits owed to determinecustomers for the amount of excess deferred income taxes caused by the TCJA. DP&L is unable to predict the outcome of this notice or the impact it may have on our Consolidated Financial Statements.2020 and 2021 annual true-ups.


PJM Transmission Enhancement Settlement
On May 31, 2018, the FERC issued an Order on Contested Settlement regarding the cost allocation method for existing and new transmission facilities contained in the PJM Interconnection’s OATT. The FERC order approved

the settlement which reduces DP&L’sAES Ohio’s transmission costs through PJM beginning in August 2018, including credits to reimburse DP&LAES Ohio for amounts overcharged in prior years. DP&LAES Ohio estimates the prior overcharge by PJM to be $41.6$40.6 million,, of which approximately $14.3$33.8 million has been repaid to DP&LAES Ohio through December 31, 20182021 and $16.5$1.7 million is classified as current in "Accounts receivable, net" and $10.8$5.1 million is classified as non-current in "Other deferrednon-current assets" on the accompanying Consolidated Balance Sheet. All of the transmission charges and credits impacted by this FERC order are items that are included for full recovery in DP&L’s nonbypassableAES Ohio’s non-bypassable TCRR. Accordingly, DP&LAES Ohio has also established offsetting regulatory liabilities. While this development will have a temporary cash flow benefit to DP&LAES Ohio, there is no impact to operating income or net income as all credits will be passed to DP&L’sAES Ohio’s customers through the TCRR, which began in November 2018.

Current regulatory assets and liabilities primarily represent costs that are being recovered per specific rate order; recovery for the remaining costs is probable, but not certain. DP&L is earning a net return on $5.5 million of this net deferral. These items include undercollection of:costs include: (i) Distribution Modernizationthe Energy Efficiency Rider, revenues, (ii) decoupling rider (see above),the Alternative Energy Rider, (iii) uncollectible riderthe Competitive Bidding Rider and (iv) energy efficiency rider. It also includesthe Transmission Cost Recovery Rider. Also included are the current portion of rate case expense costs, storm costs, Smart Grid O&M and Smart Grid R&D, which do not earn a return and are described in greater detail below. Current regulatory liabilities include the overcollection of economic development costs, legacy generation costs and certain transmission related costs, including the current portion of the following deferred costs which are described in greater detail below: unbilled fuel, regulatory compliance rider costs and deferred storm costs. As current liabilities, this includes overcollection of: (i) competitive bidding energy and auction costs, (ii) energy efficiency program costs, (iii) alternative energy rider, (iv) economic development rider, (v) certain transmission related costs including current portion of PJM transmission enhancement settlement, the transmission rate true-up and the TCJA regulatory liability (see above).

AES Ohio is earning a return on $8.1 million of this net current deferral including: (i) the Energy Efficiency Rider, (ii) the Alternative Energy Rider, (iii) the Competitive Bidding Rider and (vi) reconciliation rider.(iv) the Transmission Cost Recovery Rider. These regulatory assets are partially offset by the overcollection of economic development costs and legacy generation costs.


Pension benefits represent the qualifying FASC 715 “Compensation - Retirement Benefits” costs of our regulated operations that for ratemaking purposes are deferred for future recovery. We recognize an asset for a plan’s overfunded status or a liability for a plan’s underfunded status, and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. This regulatory asset represents the regulated portion that would otherwise be charged as a loss to OCI. As per PUCO and FERC precedents, these costs are probable of future rate recovery.


Unrecovered OVEC charges includes the portion of charges from OVEC that were not recoverable through DP&L’s fuel riderAES Ohio’s Fuel Rider from October 2014 through October 2017. DP&LAdditionally, it includes net OVEC costs from December 19, 2019 through December 31, 2019. AES Ohio expects to recover these costs through a future rate proceeding. Beginning on November 1, 2017, suchthrough December 18, 2019, current OVEC costs arewere being recovered through DP&L’s Reconciliation RiderAES Ohio’s reconciliation rider which was authorized as part of the 2017 ESP.ESP 3. Beginning January 1, 2020, AES Ohio began recovering its current net OVEC costs through its Legacy Generation Rider, established pursuant to ORC 4928.148.


Fuel costs represent unrecovered fuel costs related to DP&L’s fuel rider from 2010 through 2015 resulting from a declining SSO customer base. DP&L was granted recovery of these costs without a return through the SSO as approved in the 2017 ESP. These costs are being recovered over the three-year period that began November 1, 2017.

Regulatory compliance rider representscosts represent the long-term portion of the regulatory compliance ridercosts which was established by the 2017 ESP to recoverinclude the following costs: (i) Consumer Education Campaign, (ii) Retail Settlement System, (iii) Generation Separation, (iv) Bill Format Redesign, (v) Green Pricing Tariff and (vi) Supplier Consolidated Billing. All of these costs except for Generation Separation earn a return. These costs arewere being recovered over a three-year period.period that began November 1, 2017 through a rider approved in the ESP 3. That rider was eliminated with the approval of the ESP 1 rate plan, so the balance as of December 18, 2019 remains a regulatory asset for future recovery.


Rate case costsexpenses represents costs associated with preparing a distribution rate case. DP&Lcases. AES Ohio was granted recovery of these costs for the 2015 case which do not earn a return, as part of the DRO. Recovery of costs for the 2020 case were included in the pending filing.


Smart Grid and AMI costs represent costs incurred as a result of studying and developing distribution system upgrades and implementation of AMI. On October 19, 2010, DP&L elected to withdraw its case pertaining to the Smart Grid and AMI programs. TheIn a PUCO accepted the withdrawal in an order issued on January 5, 2011. The2011, the PUCO also indicated that it expects DP&LAES Ohio to continue to monitor other utilities’ Smart Grid and AMI programs and to explore the potential benefits of investing in the Smart Grid Plan and AMI programs and that DP&LAES Ohio will, when appropriate, file new Smart Grid and/or AMI business cases in the future. DP&L requested recovery of theseThese costs as part ofare included in the December 2018 DMP filing with the PUCOOctober 23, 2020 settlement described earlier.above.


Unamortized loss on reacquired debt represents losses on long-term debt reacquired or redeemed in prior periods that have been deferred. These deferred losses are being amortized over the lives of the original issues in accordance with the rules of the FERC and the PUCO.


Deferred storm costs represent the long-term portion of deferred costs for major storms which occurred during 20172019, 2020 and 2018. The 2017 ESP granted DP&L approval to establish a rider by which to seek recovery of these types of costs with a return. DP&L2021. AES Ohio plans to file petitions seeking recovery of each calendar year of storm costs in the following calendar year.costs. Recovery of these costs is probable, by 2020, but not certain.


Vegetation management costs represents costs incurred from outside contractors for tree trimming and other vegetation management services. Calculation terms were agreed to in the stipulation approved in the DRO. The terms were an annual baseline of $10.7 million in 2018 and $15.7 million thereafter. Amounts over the baseline will be deferred subject to an annual deferral maximum of $4.6 million. Annual spending less than the vegetation management baseline amount will result in a reduction to the regulatory asset or creation of a regulatory liability. These costs are included in AES Ohio's pending distribution rate case application.

Decoupling deferral represents the change in the revenue requirement based on a per customer methodology in the stipulation approved in the DRO and includes deferrals through December 18, 2019. These costs were previously recovered through a Decoupling Rider; however, AES Ohio withdrew its application in the ESP 3 and in doing so, the PUCO ordered on December 18, 2019 in the ESP 1 order, that AES Ohio no longer has a Decoupling Rider. As described above, AES Ohio filed a petition seeking authority to record a regulatory asset to accrue revenues that would have otherwise been collected through the Decoupling Rider.

Uncollectible deferral represents deferred uncollectible expense associated with the nonpayment of electric service, less the revenues associated with the bypassable uncollectible portion of the standard offer rate. The DRO established that these costs would be recovered in a rider outside of base rates, thus no uncollectible expense is included in base rates. These costs are included in our pending distribution rate case.

Estimated costs of removal - regulated property reflect an estimate of amounts collected in customer rates for costs that are expected to be incurred in the future to remove existing transmission and distribution property from service when the property is retired.


Deferred income taxes payable through rates represent deferred income tax liabilities recognized from the normalization of flow-through items as the result of taxes previously charged to customers. A deferred income tax asset or liability is created from a difference in income recognition between tax laws and accounting methods. As a regulated utility, DP&LAES Ohio includes in ratemaking the impacts of current income taxes and changes in deferred income tax liabilities or assets. On December 22, 2017, the TCJA was signed, which includes a provision to, among other things, reduce the federal corporate income tax rate to 21%, beginning January 1, 2018. As required by GAAP, on December 31, 2017, DP&L remeasured its deferred income tax assets and liabilities using the new expected tax rate. DP&L believes that the portion of the reduction in the net deferred tax liability which is related to deferred taxes considered in ratemaking will be used in future ratemaking to reduce jurisdictional retail rates. Accordingly, this liability reflects the estimated deferred taxes DP&LAES Ohio expects to return to customers in future periods.



TCJA regulatory liability represents the long-term portion of both protected and unprotected excess ADIT for both transmission and distribution portions, grossed up to reflect the revenue requirement. As a part of the DRO, AES Ohio agreed that savings from the TCJA attributable to distribution facilities, including the excess ADIT and the regulatory liability, constitute amounts that will be returned to customers. As a result of the TCJA and subsequent DRO, AES Ohio entered into a stipulation to resolve all remaining TCJA items related to its distribution rates, including a proposal to return no less than $4.0 million per year for the first five years unless fully returned in the first five years via a tax savings cost rider for the distribution portion of the balance. On September 26, 2019, an order approved the stipulation in its entirety.

Transmission Formula Rate Credits liability represents the amounts due to customers as a result of the implementation of transmission formula rates, which are adjusted each year based on actual revenue and costs from a previous year, as described above under FERC Proceedings.

PJM Transmission Enhancement Settlement liability represents the Transmission Enhancement Settlement charges for which AES Ohio is due a refund per FERC Order EL05-121-009 issued on May 31, 2018. The Order states that customers are due a refund for part of these charges which will be received starting August 2018 through 2025. Refunds received will be returned to customers via the transmission cost rider.

Postretirement benefits represent the qualifying FASC 715 “Compensation – Retirement Benefits” gains related to our regulated operations that, for ratemaking purposes, are probable of being reflected in future rates. We recognize an asset for a plan’s overfunded status or a liability for a plan’s underfunded status, and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. This regulatory liability represents the regulated portion that would otherwise be reflected as a gain to OCI.

In June 2018, DP&L closed on a transmission asset transaction with Duke and AEP, where ownership stakes in certain previously co-owned transmission assets were exchanged to eliminate co-ownership. Each previously co-owned transmission asset became wholly-owned by one of DP&L, Duke or AEP after the transaction. This transaction also resulted in cash proceeds to DP&L of $10.6 million and no gain or loss was recorded on the transaction.


AROs
We recognizerecognized AROs in accordance with GAAP which requires legal obligations associated with the retirement of long-lived assets to be recognized at their fair value at the time those obligations are incurred. Upon initial recognition of a legal liability, costs are capitalized as part of the related long-lived asset and depreciated over the useful life of the related asset. Our legal obligations arewere associated with the retirement of our long-lived assets, consisting primarily of river intake and discharge structures, coal unloading facilities, loading docks, ice breakersasbestos abatement and ash disposal facilities. Our generationThe AROs were for our retired Hutchings Coal Station and related primarily to Conesville,asbestos removal. These AROs were settled with the closedsale of the Hutchings EGU, and the previously owned Beckjord Facility are recorded within Asset retirement obligations on the consolidated balance sheets. The generation AROs related to our other retired or sold generation facilities are recordedCoal Station in Non-current liabilities of discontinued operations and held-for-sale businesses on the consolidated balance sheets and are excluded from the table below.

Note 54 – Fair Value


The fair values of our financial instruments are based on published sources for pricing when possible. We rely on valuation models only when no other method is available to us. The fair value of our financial instruments represents estimates of possible value that may or may not be realized in the future.


The table below presents the fair value and cost of our non-derivative financial instruments at December 31, 20182021 and 2017. See Note 6 – Derivative Instruments and Hedging Activities for the fair values of our derivative instruments.2020.

Fair Value Hierarchy
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. These inputs are then categorized as:
Level 1 (quoted prices in active markets for identical assets or liabilities);
Level 2 (observable inputs such as quoted prices for similar assets or liabilities or quoted prices in markets that are not active); or
Level 3 (unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability).


Valuations of assets and liabilities reflect the value of the instrument including the values associated with counterparty risk. We include our own credit risk and our counterparty’s credit risk in our calculation of fair value using global average default rates based on an annual study conducted by a large rating agency.


We did not have any transfers of the fair values of our financial instruments among Level 1, Level 2 or Level 3 of the fair value hierarchy during the years ended December 31, 20182021 and 2017.2020.


Debt
The fair value of debt is based on current public market prices for disclosure purposes only. Unrealized gains or losses are not recognized in the financial statements as debt is presented at the carrying value, net of unamortized premium or discount, in the financial statements. The debt amounts include the current portion payable in the next twelve months and have maturities that range from 20192025 to 2061.


Master Trust Assets
DP&LAES Ohio established a Master Trust to hold assets that could be used for the benefit of employees participating in employee benefit plans and these assets are not used for general operating purposes. ASU 2016-01 “Recognition and Measurement of Financial Assets and Financial Liabilities” was effective as of January 1, 2018. This ASU requires the change in the fair value of equity instruments to be recorded in income rather than in OCI. Equity Instruments were defined to include all mutual funds, regardless of the underlying investments. Therefore, as of January 1, 2018, AOCI of $1.6 million ($1.0 million net of tax) was reversed to Accumulated Deficit and all future changes to fair value on the Master Trust Assets will be included in income in the period that the changes occur. These changes to fair value were not material for the year ended December 31, 2018. These assets are primarily comprised of open-ended mutual funds, which are valued using the net asset value per unit. These investments are recorded at fair value within Other deferrednon-current assets on the consolidated balance sheets and classified as available for sale.

Duringequity securities. Gains and losses on these assets were not material during the yearyears ended December 31, 2018, $0.5 million ($0.4 million after tax)2021, 2020 or 2019.

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, fair value is assumed to equal carrying value. These 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.


Non-recurring Fair Value Measurements
We use the cost approach to determine the fair value of our AROs, which are estimated by discounting expected cash outflows to their present value at the initial recording of the liability. Cash outflows are based on the approximate future disposal cost as determined by market information, historical information or other management estimates. These inputs to the fair value of the AROs would be considered Level 3 inputs under the fair value hierarchy. In 2018, DPL recorded a net reduction to its ARO liability for Conesville's ash pond and landfill of $2.6 million to reflect revisions to cash flow and timing estimates. The balance of AROs was $9.4 million and $15.1 million at December 31, 2018 and 2017, respectively, which excludes AROs associated with our discontinued operations. See Note 15 – Discontinued Operations for additional information on AROs associated with our discontinued operations.

When evaluating impairment of long-lived assets, we measure fair value using the applicable fair value measurement guidance. Impairment expense is measured by comparing the fair value at the evaluation date to the carrying amount.


The following table summarizes major categories of assets measured at fair value on a nonrecurring basis during the period and their level within the fair value hierarchy:

Note 65 – Derivative Instruments and Hedging Activities


In the normal course of business, DPL enters previously entered into various financial instruments, including derivative financial instruments. We useused 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 of our derivative instruments arewere used for risk management purposes and arewere designated as cash flow hedges if they qualifyqualified under FASC 815 for accounting purposes.

Cash Flow Hedges
As part of our risk management processes, we identify 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. The effective portion of the hedging transaction is recognized in AOCI and transferred to earnings using specific identification of each contract when the forecasted hedged transaction takes place or when the forecasted hedged transaction is probable of not occurring. The ineffective portion of the cash flow hedge is recognized in earnings in the current period. All risk components were considered to determine the hedge effectiveness of the cash flow hedges. With the adoption of ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted improvements to Accounting for Hedging Activities effective January 1, 2019, we will no longer be required to calculate effectiveness and thus the entire change in the fair value of a hedging instrument will be 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.


In prior years, we entered into forward power contracts and forward natural gas contracts to manage commodity price risk exposure related to our generation of electricity. We do not hedge all commodity price risk. We reclassify gains and losses on forward power contracts from AOCI into earnings in those periods in whichAugust 2020, the contracts settle. As of December 31, 2018, we no longer held any positions in forward power contracts or forward natural gas contracts.

We have two2 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 have a combined notional amount of $140.0 million and will settle monthly based on a one-month LIBOR. As of December 31, 2017, the interest rate swaps had a combined notional amount of $200.0 million. On March 29, 2018, we$140.0 million and settled $60.0 million of these interest rate swaps due to the partial repayment of the underlying debt andmonthly based on a gain of $0.8 million was recorded as a reduction to interest expense. Since the swap was partially settled, the remaining swaps were de-designated and then re-designated with a new hypothetical derivative.one-month LIBOR. The AOCIAOCL associated with the remaining swaps will bewas amortized out of AOCIAOCL into interest expense over the remaining life of the underlying debt.

We usealso 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 AOCL into interest expense.

We used the income approach to value the swaps, which consists of forecasting future cash flows based on
contractual notional amounts and applicable and available market data as of the valuation date. The most common market data inputs used in the income approach include volatilities, spot and forward benchmark interest rates (LIBOR). Forward rates with the same tenor as the derivative instrument being valued are generally obtained from published sources, with these forward rates being assessed quarterly at a portfolio-level for reasonableness versus comparable published rates. We reclassifyreclassified gains and losses on the swaps out of AOCIAOCL and into earnings in those periods in which hedged interest payments occur.occurred.

Derivatives Not Designated as Hedges
In prior years certain derivative contracts were entered into on a regular basis as part of our risk management program but did not qualify for hedge accounting or the normal purchases and sales exceptions under FASC 815. Accordingly, such contracts were recorded at fair value with changes in the fair value charged or credited to the consolidated statements of operations in the period in which the change occurred. This is commonly referred to as “MTM accounting”. Contracts we entered into as part of our risk management program may have been settled financially, by physical delivery or net settled with the counterparty. We marked to market FTRs, natural gas futures and certain forward power contracts. For the years ended December 31, 2018, 2017, and 2016, all amounts related to such contracts are presented in discontinued operations. As of December 31, 2018, we no longer have any such contracts.

Certain qualifying derivative instruments we previously held were designated as normal purchases or normal sales contracts, as provided under GAAP. Derivative contracts that have been designated as normal purchases or normal sales under GAAP are not subject to MTM accounting treatment and are recognized in the consolidated statements of operations on an accrual basis. For the years ended December 31, 2018, 2017, and 2016, all amounts related to such contracts are presented in discontinued operations. As of December 31, 2018, we no longer have any such contracts.

The following tables show the amount and classification within the Consolidated Statements of Operations or Balance Sheets of the gains and losses on DPL’s derivatives not designated as hedging instruments for the years ended December 31, 2018, 2017 and 2016:

Significant Transactions
On March 30, 2018, DPLJuly 31, 2020, AES Ohio issued a Notice of Partial Redemption to the Trustee (U.S. Bank) on the DPL 6.75% Senior Notes due 2019. DPL notified the trustee that it was calling $101.0$140.0 million of First Mortgage Bonds and on August 3, 2020 used the $200.0proceeds to purchase at par value the $140.0 million of outstanding principal amounttax-exempt Ohio Air Quality Development Authority (OAQDA) Collateralized Pollution Control Revenue Refunding Bonds that had been issued in 2015. The new First Mortgage Bonds carry an interest rate of these3.20% and mature on July 31, 2040. The OAQDA Revenue bonds have not been legally cancelled and can be re-issued at the discretion of AES Ohio at any time. These bonds will be held in trust while we continue to evaluate market conditions and explore suitable long-term financing alternatives. Accordingly, as of December 31, 2021 and 2020, the $140.0 million variable rate OAQDA Revenue bonds are not treated as being outstanding in the Consolidated Balance Sheets.

On June 1, 2020 DPL amended its secured revolving credit facility. As a result of the amendment, the borrowing limit was reduced from $125.0 million to $110.0 million, the Total Debt to EBITDA covenant was eliminated, the EBITDA to Interest Expense covenant was reduced from 2.25 to 1.00 to 1.70 to 1.00, increasing to 1.75 to 1.00 as of September 30, 2022 and 2.00 to 1.00 as of December 31, 2022, and a trailing-twelve months minimum EBITDA covenant of $125.0 million was added, increasing to $130.0 million as of September 30, 2022 and $150.0 million as of December 31, 2022. Starting with the quarter ended September 30, 2021, the borrowing limit will be reduced by $5.0 million per quarter should DPL’s Total Debt to EBITDA ratio calculated for the period of four consecutive quarters exceed 7.00 to 1.00. As of December 31, 2021, DPL exceeded this ratio and the borrowing limit was reduced from $105.0 million to $100.0 million.

On June 19, 2020 DPL closed a $415.0 million issuance of senior unsecured notes. These notes carry an interest rate of 4.125% and mature on July 1, 2025. Proceeds from the issuance and 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 $5.1$30.8 million on April 30, 2018 with cash on hand.July 20, 2020.

On March 30, 2018, DP&L commenced a redemption of $60.0 million of outstanding tax exempt First Mortgage Bonds due 2020 at par value (plus accrued and unpaid interest). These bonds were redeemed at par plus accrued interest on April 30, 2018 with cash on hand.

On March 27, 2018, DPL made a $70.0 million prepayment to eliminate the outstanding balance of its bank term loan in full. As of March 31, 2018, the term loan was fully paid off.

On January 3, 2018, DP&L and its lenders amended DP&L's Term Loan B credit agreement. The amendment (a) modified the definition of "applicable rate", from 2.25% per annum to 1.00% per annum - in the case of the Base Rate, and from 3.25% per annum to 2.00% per annum - in the case of the Eurodollar Rate, and (b) included a "call protection" provision which stated that in the event the loan was repriced or any portion of the loans were prepaid, repaid, refinanced, substituted, or replaced on or prior July 3, 2018, such prepayment, acceleration, repayment, refinancing, substitution or replacement would be made at 101% of the principal amount so prepaid, repaid,

refinanced, substituted or replaced. After July 3, 2018 any such transaction would occur at 100% of the principal amount of the then outstanding loans. There were no such transactions prior to July 3, 2018.


Debt Covenants and Restrictions

U.S. Tax Reform
On December 22, 2017, the U.S. enacted the TCJA. The TCJA significantly changes U.S. corporate income tax law.

In 2017, we recognized the income tax effects of the TCJA in accordance with Staff Accounting Bulletin No. 118 (“SAB 118”) which provides SEC guidance on the application of FASC 740, Income Taxes, in the reporting period in which the TCJA was signed into law. Accordingly, our 2017 financial statements reflected the income tax effects of U.S. tax reform for which the accounting was complete and provisional amounts for those impacts for which the accounting under FASC 740 was incomplete, but a reasonable estimate could be determined.

We completed our calculation of the impact of the TCJA in our income tax provision forDuring the year ended December 31, 2018 in accordance with our understanding2021, DPL received a payment from AES of the TCJA and guidance available$17.5 million against its tax receivable balance as part of the date of this filing, and as a result recognized $15.5$150.0 million and $13.7 million of discrete tax expense in the fourth quarter of 2018 and 2017 respectively. Of this total, tax benefits of $1.2 million and $0.4 million are included in continuing operations in 2018 and 2017, respectively. These amounts result contribution from the remeasurement of certain deferred tax assets and liabilities as the rates changed from 35% to 21%. The most material deferred taxes to be remeasured related to property, plant and equipment. The remeasurements of deferred tax assets and liabilities related to regulated utility property of $17.0 million and $135.2 million at December 31, 2018 and 2017 were recorded as regulatory liabilities and were non-cash adjustments.

Per the terms of the order issued by the PUCO on DP&L's 2017 ESP, DPL will not make any tax-sharing payments to AES and AES will forgo collection of the payments during the term of the DMR. The agreed upon term of the DMR is three years. With commission approval, the DMR can be extended two additional years allowing for the term to potentially be five years. Both the current and non-current existing tax sharing liabilities with AES were converted into additional equity investment in DPL, per the requirements of the order. Throughout the term of the DMR, further accrued tax sharing liabilities will also be converted to additional equity. All parties agreed that the initial conversion and subsequent conversions will not be reversed.AES.

Uncertain Tax Positions
We apply the provisions of GAAP relating to the accounting for uncertainty in income taxes. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

Of the December 31, 2018The balance of unrecognized tax benefits $3.5was $0.4 million at December 31, 2021 and $1.4 million at December 31, 2020. Due to the closure of federal tax exams in 2021, the Company has reviewed its uncertain tax positions and determined that $1.0 million will not be sustained. Consequently, the $1.0 million of uncertain tax positions were reversed. The reversals did not affect the annual effective tax rate, but were reclassified to current tax payable. The total amount of remaining unrecognized tax benefits that would benefit the effective tax rate as of December 31, 2021 is due$0.4 million.

The amount anticipated to uncertaintyresult in a net decrease to unrecognized tax benefits within 12 months of December 31, 2021 is estimated to be $0.0 million.

However, audit outcomes and the timing of audit settlements and future events that would impact our previously recorded unrecognized tax benefits are subject to significant uncertainty. It is possible that the ultimate outcome of future examinations may exceed our provision for current unrecognized tax benefits.

Note 98 – Benefit Plans


Defined Contribution Plans
DP&LAES Ohio sponsors two defined contribution plans. One is for non-union employees (the management plan) and one is for collective bargaining employees (the union plan). Both plans are qualified under Section 401 of the Internal Revenue Code.


Certain non-union and union employees become eligible to participate in their respective plan upon date of hire.


Participants may elect to contribute up to 85% of eligible compensation to their plan. Non-union participant contributions are matched 100% on the first 1% of eligible compensation and 50% on the next 5% of eligible compensation and they are fully vested in their employer contributions after 2 years of service. Union participant

contributions are matched 150% but are capped at $2,400$2,650 for 20182021 and they are fully vested in their employer contributions after 3 years of service. All participants are fully vested in their own contributions.


We contributed $3.7$3.3 million, $3.1$3.2 million and $5.1$3.1 million for the years ended December 31, 2018, 20172021, 2020 and 2016,2019, respectively. DP&LAES Ohio matching contributions are paid quarterly,bi-weekly, in arrears. Therefore, theThe contributions by year may include the fourth quarterbi-weekly matching contribution that is paid in the following year. DP&Lyear in addition to employer matching true-up contributions. AES Ohio also contributes an annual bonus to the accounts of its union participants. This payment is typically made in January of the following year.


Defined Benefit PlansPlans
DP&LAES Ohio sponsors a traditional defined benefit pension plan for most of the employees of DPL and its subsidiaries. For collective bargaining employees, the defined benefits are based on a specific dollar amount per year of service. For all other employees (management employees), the traditional defined benefit pension plan is based primarily on compensation and years of service. As of December 31, 2010, this traditional pension plan formula was closed to new management employees. A participant is 100% vested in all amounts credited to his or her account upon the completion of five vesting years, as defined in The Dayton Power and Light Company Retirement Income Plan, or the participant’s death or disability. If a participant’s employment is terminated, other than by death or disability, prior to such participant becoming 100% vested in his or her account, the account shall be forfeited as of the date of termination. Employees that transferred from DP&LAES Ohio to the Service Company maintain their previous eligibility to participate in the DP&LAES Ohio pension plan.



Almost all management employees beginning employment on or after January 1, 2011 participate in a cash balance pension plan formula. Similar to the traditional pension plan for management employees, the cash balance benefits are based on compensation and years of service. A participant shall become 100% vested in all amounts credited to his or her account upon the completion of three vesting years, as defined in The Dayton Power and Light Company Retirement Income Plan, or the participant’s death or disability. If a participant’s employment is terminated, other than by death or disability, prior to such participant becoming 100% vested in his or her account, the account shall be forfeited as of the date of termination. Vested benefits in the cash balance plan are fully portable upon termination of employment.


In addition, we have a Supplemental Executive Retirement Plan (SERP) for certain retired key executives. The SERP has an immaterial unfunded liability related to agreements for retirement benefits of certain terminated and retired key executives. We also include our net liability to our partners in our co-owned generating plants related to our share of their pension liabilities within Pension, retiree and other benefits on our Consolidated Balance Sheets.


We recognize an asset for a plan’s overfunded status and a liability for a plan’s underfunded status and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. For the transmission and distribution areas of our electric business, these amounts are recorded as regulatory assets and liabilities which represent the regulated portion that would otherwise be charged or credited to AOCI.AOCL. We have historically recorded these costs on the accrual basis, and this is how these costs have been historically recovered through customer rates. This factor, combined with the historical precedents from the PUCO and FERC, make these costs probable of future rate recovery.


Postretirement Benefits
Qualified employees who retired prior to 1987 and their dependents are eligible for health care and life insurance benefits until their death, while qualified employees who retired after 1987 are eligible for life insurance benefits and partially subsidized health care. The partially subsidized health care is at the election of the employee, who pays the majoritymost of the cost, and is available only from their retirement until they are covered by Medicare. 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 $9.2$8.9 million and $12.7$9.0 million at December 31, 20182021 and 2017,2020, respectively, were not material to the consolidated financial statements in the periods covered by this report.

Significant Gains and Losses Related to Changes in the Benefit Obligation
The actuarial gain of $34.6$12.7 million decreased the benefit obligation for the year ended December 31, 20182021 and an actuarial loss of $28.1$52.7 million increased the benefit obligation for the year ended December 31, 2017.2020. The actuarial gain in 20182021 was primarily due to an increase in the discount rate whileand the actuarial loss in 20172020 was primarily due to a decrease in the discount rate.


Assumptions
Our expected return on plan asset assumptions, used to determine benefit obligations, are based on historical long-term rates of return on investments, which use the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. Current market factors, such as inflation and interest rates, as well as asset diversification and portfolio rebalancing, are evaluated when long-term capital market assumptions are determined. Peer data and historical returns are reviewed to verify reasonableness and appropriateness.


At December 31, 2018,2021, we are maintainingincreasing our long-term rate of return assumption of 6.25%to 4.60% for pension plan assets. The rate of return represents our long-term assumptions based on our long-term portfolio mix. Also, at December 31, 2018,2021, we have increased our assumed discount rate to 4.35%2.83% from 3.66%2.44% for pension expense to reflect current duration-based yield curve discount rates. A one1 percent increase in the rate of return assumption for pension would result in a decrease in 20192022 pension expense of approximately $3.2$3.4 million. A one1 percent decrease in the rate of return assumption for pension would result in an increase in 20192022 pension expense of approximately $3.2$3.4 million. A 25-basis point increase in the discount rate for pension would result in a decrease of approximately $0.1$0.5 million to 20192022 pension expense. A 25-basis point decrease in the discount rate for pension would result in an increase of approximately $0.4$0.5 million to 20192022 pension expense.


In determining the discount rate to use for valuing liabilities, we used a market yield curve on high-quality fixed income investments as of December 31, 2018.2021. We project the expected benefit payments under the plan based on participant data and based on certain assumptions concerning mortality, retirement rates, termination rates, etc. The expected benefit payments for each year are then discounted back to the measurement date using the appropriate spot rate for each half-year from the yield curve, thereby obtaining a present value of all expected future benefit payments using the yield curve. Finally, an equivalent single discount rate is determined which produces a present value equal to the present value determined using the full yield curve.


Consistent with the requirements of FASC 715, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans.


In future periods, differences in the actual return on pension plan assets and assumed return, or changes in the discount rate, will affect the timing of contributions, if any, to the plans.


The weighted average assumptions used to determine benefit obligations at December 31, 2018, 20172021, 2020 and 20162019 were:

Pension Plan Assets
Plan assets are invested in multiple asset classes using a total return investment approach whereby a mix of equity securities, debt securitiesde-risking framework designed to manage the Plan's funded status volatility and other investments are used to preserve asset values, diversify risk and achieve our target investment return benchmark.minimize future cash contributions. Investment strategies and asset allocations are based on careful consideration of plan liabilities,intended to allocate additional assets to the plan'sfixed income asset class should the Plan's funded status improve and our financial condition.is therefore broadly described as the Dynamic De-risking Strategy. Investment performance and asset allocation are measured and monitored on an ongoing basis.


Plan assets are managed in a balanced portfolio comprised of two major components: an equity portionreturn seeking assets and a fixed income portion.liability hedging assets. The expected role of plan equity investmentsreturn seeking assets is to maximize the long-term real growthprovide additional return with associated higher levels of plan assets,risk, while the role of liability hedging assets is to correlate the interest rate of the fixed income investments is to generate current income, provide for more stable periodic returns and provide some protection against a prolonged decline inwith that of the market value of plan equity investments.Plan's liabilities.


Long-term strategic asset allocation guidelines, as well as short-term tacticalStrategic asset allocation guidelines are determined by a Risk/Advisory Committee and approved by a Fiduciary Committee. These allocations consider the plan’s long-term objectives. The long-term target allocations for plan assets are 24%40%52%50% for equity securitiesreturn seeking assets and 47%50%65%60% for fixed income securities. Equity securitiesliability hedging assets. Return seeking assets include U.S. and international equity, while fixed income securitiesliability hedging assets include long-duration and high-yield bond funds and emerging market debt funds.


Tactically,The investment approach is to move the committees, onPlan to a short-term basis, will make asset allocations that are outsidemore de-risked position, if and when the long-termoverall funded status of the Plan improves, by periodically rebalancing the allocation guidelines. The short-term allocation positions are likelyof the Plan's investments in growth assets and liability hedging assets in accordance with the committee's glide path. This strategy requires the daily monitoring of the Plan's ratio of assets to not exceed one-yearliabilities in duration. In additionorder to determine whether approved trigger points have been met, requiring the equity and fixed income investments,rebalancing of the short-term allocation may also include a relatively small allocation to alternative investments. The plan currently has a small target allocation in a core property fund.assets.

Pension Funding
We generally fund pension plan benefits as accrued in accordance with the minimum funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA) and, in addition, make voluntary contributions from time to time. We contributed $7.5$9.8 million to the pension plan in the year ended December 31, 20182021, and $5.0$7.5 million to the pension plan in each of the years ended December 31, 20172020 and 2016.2019.


We expect to make contributions of $0.4$0.2 million to our SERP in 20192022 to cover benefit payments. We also expect to make contributions of $7.5 million to our pension plan during 2019.2022.


Funding for the qualified Defined Benefit Pension Plan is based upon actuarially determined contributions that consider the amount deductible for income tax purposes and the minimum contribution required under ERISA, as amended by the Pension Protection Act of 2006, as well as targeted funding levels necessary to meet certain thresholds.


From an ERISA funding perspective, DP&L’sAES Ohio’s funded target liability percentage was estimated to be 101%114%. In addition, DP&LAES Ohio must also contribute the normal service cost earned by active participants during the plan year. The funding of normal cost is expected to be approximately $5.4$5.8 million in 2019,2022, which includes $1.9$1.7 million for plan expenses. Each year thereafter, if the plan’s underfunding increases to more than the present value of the remaining annual installments, the excess is separately amortized over a seven-year period. DP&L’sseven years. AES Ohio’s funding policy for the pension plans is to contribute annually no less than the minimum required by applicable law, and no more than the maximum amount that can be deducted for federal income tax purposes.

Note 109EquityShareholder's Deficit

Redeemable Preferred Stock of Subsidiary
On October 13, 2016 (the "Redemption Date"), DPL's subsidiary, DP&L redeemed all of its issued and outstanding preferred stock, consisting of the following series: Preferred Stock, 3.75% Series A, Cumulative (the “Series A Stock”); Preferred Stock, 3.75% Series B, Cumulative (the “Series B Stock”); and Preferred Stock, 3.90% Series C, Cumulative (the “Series C Stock” and, together with the Series A Stock and the Series B Stock, the “Preferred Stock”). On the Redemption Date, the Preferred Stock of each series was redeemed at the following prices as specified in DP&L’s Amended and Restated Articles of Incorporation, plus, in each case an amount equal to all accrued dividends payable with respect to such Preferred Stock to the Redemption Date: a price of $102.50 per share for the Series A Stock, a price of $103.00 per share for the Series B Stock, and a price of $101.00 per share for the Series C Stock. Dividends on the Preferred Stock ceased to accrue on the Redemption Date. Upon redemption, the Preferred Stock was no longer outstanding, and all rights of the holders thereof as shareholders of DP&L, except the right to payment of the redemption price, ceased to exist. The difference between the carrying value of the Redeemable Preferred Stock of Subsidiary and the redemption amount was charged to Other paid-in capital.


Dividend Restrictions
DPL’s Amended Articles of Incorporation (the Articles) and the DPL Credit Agreement contain provisions which state that DPL may not make a distribution to its shareholder or make a loan to any of its affiliates (other than its subsidiaries), unless: (a) there exists no Event of Default (as defined in the Articles) and no such Event of Default would result from the making of the distribution or loan; and either (b)(i) at the time of, and/or as a result of, the distribution or loan, DPL’s leverage ratio does not exceed 0.67 to 1.00 and DPL’s interest coverage ratio is not less than 2.50 to 1.00 or, (b)(ii) if such ratios are not within the parameters, DPL’s senior long-term debt rating from one of the three major credit rating agencies is at least investment grade. Further, the restrictions on the payment of distributions to a shareholder and the making of loans to its affiliates (other than subsidiaries) cease to be in effect if the three major credit rating agencies confirm that a lowering of DPL’s senior long-term debt rating below investment grade by the credit rating agencies would not occur without these restrictions. DPL is also restricted from making dividend and tax sharing payments from DPL to AES per its 2017 ESP. This order restricts dividend payments from DPL to AES during the term of the ESP and restricts tax sharing payments from DPL to AES during the term of the DMR.restrictions.

Capital Contributions from AES
In DP&L's approved six-year 2017 ESP, the PUCO imposed restrictions on DPL making dividend payments to its parent company, AES, during the termDuring each 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.

As such, AES agreed to make non-cash capital contributions of $97.1 million and waive the amount owed to it by DPL related to tax-sharing payments for current tax liabilities through December 31, 2017. For the yearyears ended December 31, 2018,2021 and 2020, DPL received a $150.0 million cash contribution from AES, made capitalwhich DPL then used to make a $150.0 million equity contribution to AES Ohio. The cash contributions at DPL represented equity contributions of $40.0$132.5 million by convertingand $98.0 million in 2021 and 2020, respectively; and payments of $17.5 million and $52.0 million against its tax receivable in 2021 and 2020, respectively.

Note 1110 – Contractual Obligations, Commercial Commitments and Contingencies

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

At December 31, 2018, DPL had $23.6 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 present and future obligations of AES Ohio Generation to such beneficiaries and are terminable at any time by DPL upon written notice to the beneficiaries. We had no outstanding balance of obligations for commercial transactions covered by these guarantees at December 31, 2018. The carrying amount of obligations for commercial transactions covered by these guarantees and recorded in our Consolidated Balance Sheets was $0.9 million at December 31, 2017.

To date, DPL has not incurred any losses related to these guarantees and we believe it is remote that DPL would be required to perform or incur any losses in the future associated with any of the above guarantees.


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. At December 31, 2018, DP&L2021, AES Ohio could be responsible for the repayment of 4.9%, or $68.1$55.5 million, of a $1,389.6$1,131.7 million debt obligation comprised of both fixed and variable rate securities with maturities between 20192022 and 2040. OVEC could also seek additional contributions from us to avoid a default in the event that other OVEC members defaulted on their respective OVEC obligations. One of the other OVEC members, with a 4.85% interest in OVEC, filed for bankruptcy protection and the bankruptcy court approved that member's rejection of the OVEC arrangement and its related obligations on July 31, 2018. We do not expect these events to have a material impact on our financial condition, results of operations or cash flows.


Contractual Obligations and Commercial Commitments
We enter into various contractual obligations and other commercial commitments that may affect the liquidity of our operations. At December 31, 2018,2021, these include:

Purchase orders and other contractual obligations:
At December 31, 2018, 2021, DPL had various other contractual obligations including non-cancelable contracts to purchase goods and services with various terms and expiration dates. Due to uncertainty regarding the timing and payment of future obligations to the Service Company, and DPL's ability to terminate such obligations upon 90 days' notice, we have excluded such amounts in the contractual obligations table aboveabove.



Contingencies
In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under laws and regulations. We believe the amounts provided in our Consolidated Financial Statements, as prescribed by GAAP, are adequate in light ofconsidering 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, including the matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in our Consolidated Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided as of December 31, 2018,2021, cannot be reasonably determined.


Environmental Matters
DPL’s facilities and operations are subject to a wide range of federal, state and local environmental laws, rules and regulations. The environmental issues that may affect us include the following. However, as described further below,following; however, as a result ofDPL’s retirement of its Stuart and Killen generating stations, the sale of its ownership interest in the Miami Fort and Zimmer generating stations, the planned 2020 retirement of Conesville and our exiting of our generation business, certain of these environmental regulations and lawsrequirements are now notno longer expected to have a material impact on DPL with respect to and AES Ohio. See Item 1 - Business - Environmental Matters for a more comprehensive discussion of these generating stations.and other environmental matters impacting us.
The federal CAA and state laws and regulations (including SIPs) which require compliance, obtaining permits and reporting as to air emissions;
Litigation with federal and certain state governments and certain special interest 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 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. The majorityMost of the solid waste created from the combustion of coal and fossil fuels is fly ash and other coal combustion by-products.


In addition to imposing continuing compliance obligations, theseenvironmental laws, rules 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 laws, rules and 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 a number of 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 or cash flows.


We have several pending environmental matters associated with our current and previously ownedpreviously-owned and operated coal-fired generation units. Some ofWe do not expect these matters couldto have a material adverse impactsimpact on our results of operations, financial condition or cash flows.

Note 1312 – Business Segments


Beginning with the second quarter of 2018, DPL has presented the results of operations of Miami Fort Station, Zimmer Station, the Peaker Assets, Stuart Station and Killen Station as discontinued operations as a group of components for all periods presented. For more information, see Note 15 – Discontinued Operations of Notes to DPL's Consolidated Financial Statements. AES Ohio Generation now only has operating activity coming from its

undivided ownership interest in Conesville, which does not meet the threshold to be a separate reportable operating segment. Because of this, DPL now manages its business through only one1 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 segments. The Utility segment is discussed further below:


Utility Segment
The Utility segment is comprised primarily 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 525,000534,000 retail customers who are located in a 6,000 square6,000-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 and recordsrecording 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’s Beckjord Facility,AES Ohio’s Hutchings Coal Station, which was closed in 20142013 and transferred to a third party in the firstfourth quarter of 2018, and the Hutchings EGU, which was closed in 2013. These assets did not transfer to AES Ohio Generation as part of DP&L's Generation Separation on October 1, 2017. Thus, they are grouped within the Utility segment for segment reporting purposes. In addition, regulatory deferrals and collections, which include fuel deferrals in historical periods, are included in the Utility segment.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 andas well as adjustments related to purchase accounting from the Merger.DPL's undivided interest in Conesville is now included within the "Other" column as it no longer meets the requirement for disclosure as a reportable operating segment, since the results of operations of the other generation plants are now presented as discontinued operations. The accounting policies of the reportable segments are the same as those described in Note 1 – Overview and Summary of Significant Accounting Policies. Intersegment sales, costs of sales and profitsexpenses are eliminated in consolidation. Certain shared and corporate costs are allocated amongbetween "Other" and the Utility reporting segments.segment.

Note 1413 – 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 of promised goods or services 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.


Retail Revenues DP&Lrevenue
AES Ohio energy sales to utility customers are based on the reading of meters at the customer's location that occurs on a systematic basis throughout the month. DP&LAES Ohio sells electricity directly to end-users, such as homes and businesses, and bills customers directly. Performance obligations for retail revenues are satisfied over time as energy is delivered and the same method is used to measure progress, and thus the performance obligation meets the criteria to be considered a series. This includes both the promise to transfer energy and other distribution and/or transmission services.


In exchange for the exclusive right to sell or distribute electricity in our service area, DP&LAES Ohio is subject to rate regulation by federal and state regulators. This regulation sets the framework for the prices (“tariffs”) that DP&L AES Ohio is allowed to charge customers for electricity. Since tariffs are approved by the regulator, the price that DP&LAES Ohio has the right to bill corresponds directly with the value to the customer of DP&L'sAES Ohio's performance completed in each period. Therefore, revenue under these contracts is recognized using an output method measured by the MWhs delivered each month at the approved tariff.


In cases where a customer chooses to receive generation services from a CRES provider, the price for generation services is negotiated between the customer and the CRES provider, and DP&LAES Ohio only serves as a billing agent if requested by the CRES provider. As such, DP&LAES Ohio recognizes the consolidated billing arrangement with the CRES provider on a net basis, thereby recording no revenue for the generation component. Retail revenue from these customers would only be related to transmission and distribution charges.


Wholesale Revenues – All of the power produced from DPL's ownership interest in Conesville and DP&L'srevenue
AES Ohio's share of the power produced at OVEC is sold to PJM and these revenues are classified as Wholesale revenues.


89

In PJM, the promise to sell energy as wholesale revenue is separately identifiable from participation in the capacity market and the two products can be transacted independently of one another. Therefore, wholesale revenues are a separate contract with a single performance obligation. Revenue is recorded based on the quantities (MWh) delivered in each hour during each month at the spot price, making the contract effectively “month-to-month”.


RTO Revenues ancillary revenue
Compensation for use of DP&L’sAES Ohio’s transmission assets and compensation for various ancillary services are classified as RTO ancillary revenues. As DP&LAES Ohio owns and operates transmission lines in southwest Ohio within PJM, demand charges collected from network customers by PJM are then allocated to the appropriate transmission owners (i.e. DP&LAES Ohio) and recognized as transmission revenues. Additionally, as an owner of generation and transmission assets within PJM, DPL is compensated for various ancillary services; such as reactive supply, regulation services, scheduling reserves, operating reserves, spinning/synchronized reserves as well as congestion credits that are provided to PJM via these assets.


Transmission revenues have a single performance obligation, as transmission services represent a distinct service. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The price that DP&LAES Ohio, as the transmission operator, has the right to bill (received as a credit from PJM) corresponds directly with the value to the customer of performance completed in each period, as the price paid is the allocation of the tariff rate (as approved by the regulator) charged to network participants.


Ancillary serviceCapacity revenue
AES Ohio records its share of OVEC capacity revenues haveas Capacity revenues. The capacity price is set through a singlecompetitive auction process established by PJM. Depending on the availability and performance obligation, as they represent a distinct service. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The price that DPL has the right to bill corresponds directly with the value to the customer of performance completed in each period as the price paid is at the market price or allocation of the tariff rate (which was approved by the regulator) charged to network participants.

RTO Capacity Revenues – Compensation received from PJM for making installed generation capacity available to satisfy system integrity and reliability requirements is classified as RTO capacity revenues. Capacity, which is a stand-ready obligation to deliver energy when called upon by the RTO, is measured using MWs. If plant availability exceeds a contractual target, weOVEC units, there may receive abe additional performance bonus payment, or if the plant availability falls below a guaranteed minimum target, we may incur a non-availability penalty. Such bonuses or penalties, represent a form of variable consideration and are estimated andwhich would be recognized whenonly if it isbecomes probable that theresuch bonus or penalties will not be a significant reversal and therefore the transaction price is recognized on an output basis based on the MWs.incurred.


RTO capacity revenues have a single performance obligation, as capacity is a distinct good. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The capacity price is set through a competitive auction process established by PJM.

Note 1514 – Discontinued Operations


Conesville - In May 2020, AEP, the operator of the formerly co-owned Conesville EGU, retired Conesville Unit 4 as planned. On December 8, 2017, June 5, 2020, DPLand AES Ohio Generation, together with AEP, completed the sale transactiontransfer of their entire undivided interestinterests in the Miami Fort Station andretired Unit 4, including the Zimmer Station, which resulted inassociated environmental liabilities, to an unaffiliated third-party purchaser. As a result, DPL recognized a gain on salethe transfer of $14.0$4.5 million for the year ended December 31, 2017.2020. For the transaction, DPL will make quarterly cash expenditures, totaling $4.0 million, through July 2022, of which $3.4 million has been paid through December 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 March 27, 2018, 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 sale transactiontransfer of the Peaker assetsretired generating facilities, including the associated environmental liabilities, to Kimura Power, LLC, which resulted inan unaffiliated third-party purchaser. As a lossresult, DPL made cash expenditures of $51.0 million and recognized a gain on salethe transfer of $1.9$20.0 million for the year ended December 31, 2018. Further, on May 31, 2018, 2019.

DPL determined that the transfer of Conesville and the previous transfers and sales of other AES Ohio Generation retiredassets constitute the Stuart Station coal-fired and diesel-fired generating units and the Killen Station coal-fired generating unit and combustion turbine,disposal of a group of components, which, as planned. Consequently, in the second quarter of 2018, DPL determined thata whole, represent a strategic shift to exit its AES Ohio Generation business. As such, the disposal of this group of components as a whole represents a strategic shift by us to exit generation, and, as such, qualifies to be presented as discontinued operations. Therefore, the results of operations and financial position forof this group of components were reported as such in the Consolidated Statements of Operations and Consolidated Balance Sheets for all periods presented.

Previously, on January 1, 2016, DPL closed on the sale of DPLER, its competitive retail business. The sale agreement was signed on December 28, 2015, and DPL received $75.5 million of restricted cash on December 31, 2015 for the sale. DPL recorded a gain on this transaction of $49.2 million in the first quarter of 2016. The gain included the impact of DPLER’s liability to DP&L that transferred with the sale on January 1, 2016. As such, the results of operations of DPLER were also reported as discontinued operations in the Consolidated Statements of Operations for the year ended December 31, 2016.

Regulatory Accounting
Description of the MatterAs described in Note 2 to the financial statements, the Company applies the provisions of FASC 980 “Regulated Operations,” which gives recognition to the ratemaking and accounting practices of the PUCO and the FERC. Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory liabilities generally represent obligations to provide refunds or future rate reductions to customers for previous overcollections or the deferral of revenues collected for costs that the Company expects to incur in the future. Accounting for the economics of rate regulation affects multiple financial statement line items, including property, plant, and equipment; regulatory assets and liabilities; revenues; and depreciation expense, and related disclosures in the Company’s financial statements.
Auditing the Company’s regulatory accounting was complex due to significant judgments made by management to support its assertions about the impact of future regulatory orders on the financial statements. In particular, there is subjectivity involved in assessing the impact of current and future regulatory orders on events that have occurred through December 31, 2021, judgment required to evaluate the relevance and reliability of audit evidence to support impacted account balances and disclosures, and judgments involved in assessing the probability of recovery in future rates of incurred costs or refunds to customers. These assumptions have a significant effect on the financial statements and related disclosures.
How We Addressed the Matter in Our AuditTo test the Company’s accounting for regulatory assets and liabilities, our audit procedures included, among others, reviewing relevant regulatory orders, statutes and interpretations; filings made by intervening parties; and other publicly available information, to assess the likelihood of recovery of regulatory assets in future rates or of a refund or future reduction in rates for regulatory liabilities based on precedents for the treatment of similar costs under similar circumstances. We evaluated the Company’s assertions regarding the probability of recovery of regulatory assets or refund or future reduction in rates for regulatory liabilities, to assess the Company’s assertion that amounts are probable of recovery or of a refund or future reduction in rates.

Note 1 – Overview and Summary of Significant Accounting Policies


Description of Business
DP&L AES Ohio is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave consumers the right to choose the electric generation supplier from whom they purchase retail generation service,service; however, transmission and distributiondistribution services are still regulated. DP&LAES Ohio has the exclusive right to provide such service to its approximately 525,000 534,000 customers located in West Central Ohio. 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. Since January 2016, DP&L has been sourcingAES Ohio sources all of the generation for its SSO customers through a competitive bid process. Through September 30, 2017, DP&LAES Ohio owned undivided interests inmultiple coal-fired power stationsthe retired Hutchings Coal Station until its transfer in 2020 and multiple peaking electric generating facilities as well ascurrently owns numerous transmission facilities. On October 1, 2017, the DP&L-owned generating facilities, excluding the Beckjord Facility and Hutchings EGU, were transferred to AES Ohio Generation, an affiliate of DP&L and wholly-owned subsidiary of DPL, through an asset contribution agreement to a subsidiary that was merged into AES Ohio Generation. Also, Stuart Station Unit 1 was retired on October 1, 2017. Principal industries located in DP&L’sAES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. DP&L'sAES Ohio's sales reflect the generalgeneral economic conditions, seasonal weather patterns of the area, and the market price of electricity. Through the dateelectricity and customer energy efficiency initiatives. AES Ohio also sells its proportional share of Generation Separation, DP&L sold energy and capacity from its investment in OVEC into the wholesale market. As a result of Generation Separation, DP&L nowAES Ohio has only has one reportable segment, Transmission and Distribution.the Utility segment. In addition to DP&L'sAES Ohio's electric transmission and distribution businesses, the Transmission and DistributionUtility segment includes revenues and costs associated with DP&L'sAES Ohio's investment in OVEC and the historical results of DP&L’s Beckjord andAES Ohio’s retired Hutchings Coal generating facilities,Station, which were either closed orwas sold in prior periods.2020.


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 or overcollections of riders.

DP&L employed 647 people at January 31, 2019. Approximately 58% of all employees are under a collective bargaining agreement.


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

Through June 2018, DP&L had undivided ownership interests in numerous transmission facilities. These undivided interests in jointly-owned facilities were accounted for on a pro rata basis in the Financial Statements. In June 2018, DP&L closed on a transmission asset transaction with Duke and AEP, where ownership stakes in certain previously co-owned transmission assets were exchanged to eliminate co-ownership. Each previously co-owned transmission asset became wholly-owned by one of DP&L, Duke or AEP after the transaction. See Note 4 – Property, Plant and Equipment for more information.


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


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


Use of Management Estimates
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: 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 receivables and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; the valuation of AROs; and assets and liabilities related to employee benefits.



Cash and Cash Equivalents
Cash and cash equivalents are stated at cost, which approximates fair value. All highly liquid short-term investments with original maturities of three months or less are considered cash equivalents.

Restricted Cash
Restricted cash includes cash which is restricted as to withdrawal or usage. The restrictions relate to cash required for certain balance requirements.

2021$2.8 $(0.4)$(3.5)$1.4 $0.3 
2020$0.4 $3.0 $(2.3)$1.7 $2.8 
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 would impact collectability, as applicable, including the economic impacts of the COVID-19 pandemic on our receivable balance as of December 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 through September 1, 2020 due to the economic impacts of COVID-19. This order along with the economic impacts of COVID-19 has resulted in an increase in past due customer receivable balances in 2020, and thus the current period provision and the allowance for credit losses increased during the prior year. During 2021, the current period provision and allowance for credit losses decreased due to lower past due customer receivable balances. See Note 14 – Risks & Uncertainties for additional discussion of the COVID-19 pandemic. As discussed in Note 2 – Regulatory Matters, AES Ohio’s uncollectible expense is deferred for future collection.

Inventories
Inventories are carried at average cost, net of reserves, and include materials and supplies used for utility operations.

Regulatory Accounting
As a regulated utility, AES Ohio applies the provisions of FASC 980 “Regulated Operations”, which gives recognition to the ratemaking and accounting practices of the PUCO and the FERC. Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory assets have been included as allowable costs for ratemaking purposes, as authorized by the PUCO or established regulatory practices. Regulatory liabilities generally represent obligations to make refunds or future rate reductions to customers for previous over collections or the deferral of revenues collected for costs that AES Ohio expects to incur in the future.
103

Table of Contents

The deferral of costs (as regulatory assets) is appropriate only when the future recovery of such costs is probable. In assessing probability, we consider such factors as specific orders from the PUCO or the FERC, regulatory precedent and the current regulatory environment. To the extent recovery of costs is no longer deemed probable, related regulatory assets would be required to be expensed in current period earnings. Our regulatory assets and liabilities have been created pursuant to a specific order of the PUCO or the FERC or established regulatory practices, such as other utilities under the jurisdiction of the PUCO or the FERC being granted recovery of similar costs. It is probable, but not certain, that these regulatory assets will be recoverable, subject to approval by the PUCO or the FERC. Regulatory assets and liabilities are classified as current or non-current based on the term in which recovery is expected. See Note 2 – Regulatory Matters for more information.

Property, Plant and Equipment
New property, plant and equipment additions are stated at cost. For regulated transmission and distribution property, cost includes direct labor and material, allocable overhead expenses and an allowance for funds used during construction (AFUDC). AFUDC represents the cost of borrowed funds and equity used to finance regulated construction projects. Capitalization of AFUDC and interest ceases at either project completion or at the date specified by regulators. AFUDC and capitalized interest was $3.7 million, $3.0 million and $3.2 million in the years ended December 31, 2021, 2020 and 2019, respectively.

For substantially all depreciable property, when a unit of property is retired, the original cost of that property less any salvage value is charged to Accumulated depreciation and amortization, consistent with composite depreciation practices.

Impairment of Long-lived Assets
GAAP requires that we test long-lived assets for impairment when indicators of impairment exist. If an asset is deemed to be impaired, we are required to write down the asset to its fair value with a charge to current earnings. The net book value of our property, plant, and equipment was $1,679.2 million and $1,544.0 million as of December 31, 2021 and 2020, respectively. We do not believe any of these assets are currently impaired. In making this assessment, we consider such factors as: the overall condition and distribution capacity of the assets; the expected ability to recover additional expenditures in the assets; and the anticipated demand and relative pricing of retail electricity in our service territory.

Depreciation
Depreciation expense is calculated using the straight-line method, which allocates the cost of property over its estimated useful life. For AES Ohio’s transmission and distribution assets, straight-line depreciation is applied monthly on an average composite basis using group rates that approximated 2.8% in 2021, 2.8% in 2020 and 2.9% in 2019. Depreciation expense was $71.6 million, $68.6 million and $66.5 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Intangibles
Intangibles include software and renewable energy credits. Renewable energy credits are carried on a weighted average cost basis and amortized as they are used or retired.

Software is amortized over seven years. Amortization expense was $3.0 million, $3.2 million and $4.3 million for the years ended December 31, 2021, 2020 and 2019, respectively. The estimated amortization expense of this internal-use software over the next five years is $9.9 million ($2.8 million in 2022, $2.1 million in 2023, $1.9 million in 2024, $1.6 million in 2025 and $1.5 million in 2026).

Implementation Costs Related to Software as a Service
AES Ohio has recorded prepayments for implementation costs related to software as a service in support of utility customer services of $8.0 million and $4.1 million as of December 31, 2021 and 2020, respectively, and these are recorded within Other Non-current Assets on the accompanying Balance Sheets.

Debt Issuance Costs
Costs incurred in connection with the issuance of long-term debt are deferred and presented as a direct reduction from the face amount of that debt and amortized over the related financing period using the effective interest method. Debt issuance costs related to a line-of-credit or revolving credit facility are deferred and presented as an asset and amortized over the related financing period. Make-whole payments in connection with early debt retirements are classified as cash flows used in financing activities.

Financial Instruments
Our Master Trust investments in debt and equity financial instruments of publicly traded entities are classified as equity investments. These equity securities are carried at fair value and unrealized gains and losses on these securities are recorded in Other income. As these financial instruments are held to be used for the benefit of employees or former employees participating in employee benefit plans and are not used for general operating purposes, they are classified as non-current in Other non-current assets on the Balance Sheets. See Note 4 – Fair Value for additional information.

Financial Derivatives
We have contracts involving the physical delivery of energy. Because these contracts qualify for the normal purchases and normal sales scope exception in ASC 815, we have elected to account for them as accrual contracts, which are not adjusted for changes in fair value.

We have, in the past, used interest rate hedges to manage the interest rate risk of our variable rate debt. We used cash flow hedge accounting when the hedge or a portion of the hedge was deemed to be highly effective, which resulted in changes in fair value being recorded within accumulated other comprehensive loss, a component of shareholder’s equity. We elected not to offset net derivative positions in the financial statements. Accordingly, we did not offset such derivative positions against the fair value of amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral under master netting agreements. See Note 5 – Derivative Instruments and Hedging Activities for additional information.

Insurance and Claims Costs
In addition to insurance obtained from third-party providers, MVIC, a wholly-owned captive subsidiary of DPL, provides insurance coverage solely to us and other DPL subsidiaries for workers’ compensation, general liability and property damage on an ongoing basis. AES Ohio is responsible for claims costs below certain coverage thresholds of MVIC and third-party insurers for the insurance coverage noted above. AES Ohio has estimated liabilities for medical, life, disability and other reserves for claims costs below certain coverage thresholds of third-party providers of approximately $3.4 million and $3.5 million at December 31, 2021 and 2020, respectively, within Accrued and other current liabilities and Other non-current liabilities on the balance sheets. The estimated liabilities for workers’ compensation, medical, life and disability costs at AES Ohio are actuarially determined using certain assumptions. There is uncertainty associated with these loss estimates, and actual results may differ from the estimates. Modification of these loss estimates based on experience and changed circumstances is reflected in the period in which the estimate is re-evaluated.

Revenue Recognition
Revenues are recognized from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Energy sales to customers are based on the reading of their meters that occurs on a systematic basis throughout the month. We recognize the revenues on our Statements of Operations using an accrual method for retail and other energy sales that have not yet been billed, but where electricity has been consumed. This is termed “unbilled revenues” and is a widely recognized and accepted practice for utilities. At the end of each month, unbilled revenues are determined by the estimation of unbilled energy provided to customers since the date of the last meter reading, estimated line losses, the assignment of unbilled energy provided to customer classes and the average rate per customer class.

The power sales and purchases within DP&L’s service territory are reported on a net hourly basis as revenues or purchased power on our Statements of Operations. We record expenses when purchased electricity is received and when expenses are incurred. For additional information, see Note 1312 – Revenue.


AllowanceAccounting for Uncollectible AccountsTaxes Collected from Customers and Remitted to Governmental Authorities
We establish provisionsAES Ohio collects certain excise taxes levied by state or local governments from its customers. AES Ohio’s excise taxes and certain other taxes are accounted for uncollectible accounts by using both historical average loss percentages to project future losseson a net basis and by establishing specific provisions for known credit issues. Amounts are written off when reasonable collections efforts have been exhausted.recorded as a reduction in revenues in the accompanying Statements of Operations. The amounts of such taxes were as follows:

Years ended December 31,

Property, Plant and Equipment
We record our ownership share of our undivided interest in jointly-owned transmission and distribution property as an asset in property, plant and equipment. New property, plant and equipment additions are stated at cost. For regulated transmission and distribution property, cost includes direct labor and material, allocable overhead expenses and an allowance for funds used during construction (AFUDC). AFUDC represents the cost of borrowed funds and equity used to finance regulated construction projects. For non-regulated property, cost also includes capitalized interest. Capitalization of AFUDC and interest ceases at either project completion or at the date specified by regulators AFUDC and capitalized interest was $0.5 million, $1.5 million and $2.0 million for the years ended December 31, 2018, 2017 and 2016, respectively.

For substantially all depreciable property, when a unit of property is retired, the original cost of that property less any salvage value is charged to Accumulated depreciation and amortization, consistent with composite depreciation practices.

Property is evaluated for impairment when events or changes in circumstances indicate that its carrying amount may not be recoverable.


Repairs and Maintenance
Costs associated with maintenance activities are recognized at the time the work is performed. These costs, which include labor, materials and supplies and outside services required to maintain equipment and facilities, are capitalized or expensed based on defined units of property.

Table of Contents
Depreciation expense is calculated usingPension and Postretirement Benefits
We recognize in our Balance Sheets an asset or liability reflecting the straight-line method,funded status of pension and other postretirement plans with current-year changes from actuarial gains or losses related to our regulated operations, that would otherwise be recognized in AOCL, recorded as a regulatory asset as this can be recovered through future rates. Such changes that are not related to our regulated operations are recognized in AOCL. All plan assets are recorded at fair value. We follow the measurement date provisions of the accounting guidance, which allocates the costrequire a year-end measurement date of property over its estimated useful life. For DP&L’s transmissionplan assets and distribution assets, straight-line depreciation is applied monthly on an average composite basis using group rates. For DP&L’s transmissionobligations for all defined benefit plans.

We account for and distribution assets, straight-line depreciation is applied on an average annual composite basis using group rates that approximated 3.0%disclose pension and postretirement benefits in 2018, 3.4% in 2017 and 4.6% in 2016. Depreciation expense was $68.2 million, $69.6 million and $64.3 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Regulatory Accounting
As a regulated utility, DP&L appliesaccordance with the provisions of FASC 980 “Regulated Operations”, which gives recognitionGAAP relating to the ratemakingaccounting for pension and accounting practicesother postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the PUCOplans. Consistent with the requirements of FASC 715, we apply a disaggregated discount rate approach for determining service cost and the FERC. Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory assets have been included as allowable costsinterest cost for ratemaking purposes, as authorized by the PUCO or established regulatory practices. Regulatory liabilities generally represent obligations to make refunds or future rate reductions toour defined benefit pension plans and postretirement plans.


customers for previous over collections or the deferral of revenues collected for costs that DP&L expects to incur in the future.

The deferral of costs (as regulatory assets) is appropriate only when the future recovery of such costs is probable. In assessing probability, we consider such factors as specific orders from the PUCO or FERC, regulatory precedent and the current regulatory environment. To the extent recovery of costs is no longer deemed probable, related regulatory assets would be required to be expensed in current period earnings. Our regulatory assets and liabilities have been created pursuant to a specific order of the PUCO or FERC or established regulatory practices, such as other utilities under the jurisdiction of the PUCO or FERC being granted recovery of similar costs. It is probable, but not certain, that these regulatory assets will be recoverable, subject to PUCO or FERC approval. Regulatory assets and liabilities are classified as current or non-current based on the term in which recovery is expected See Note 38Regulatory MattersBenefit Plans for more information.

Inventories
Inventories are carried at average cost and include materials and supplies used for utility operations.

Intangibles
Intangibles include software, emission allowances and renewable energy credits. Emission allowances are carried on a first-in, first-out (FIFO) basis for purchased emission allowances. Net gains or losses on the sale of excess emission allowances, representing the difference between the sales proceeds and the cost of emission allowances, are recorded as a component of our fuel costs and are reflected in Operating income when realized. Emission allowances are amortized as they are used in our operations on a FIFO basis. Renewable energy credits are carried on a weighted average cost basis and amortized as they are used or retired.

Software is amortized over seven yearsAmortization expense was $6.3 million, $5.7 million and $6.7 million for the years ended December 31, 2018, 2017 and 2016, respectively. The estimated amortization expense of this internal-use software over the next five years is $11.1 million ($3.5 million in 2019, $2.4 million in 2020, $2.2 million in 2021, $1.8 million in 2022 and $1.2 million in 2023).


Income Taxes
Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of the existing assets and liabilities and their respective income tax bases. We establish an allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. Our tax positions are evaluated under a more likely than not recognition threshold and measurement analysis before they are recognized for financial statement reporting. Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid within one year. Our policy for interest and penalties is to recognize interest and penalties as a component of the provision for income taxes in the Statement of Operations.


Income taxes payable, which are includable in allowable costs for ratemaking purposes in future years, are recorded as regulatory assets or liabilityliabilities with a corresponding deferred tax liability or asset. Investment tax credits that reduced federal income taxes in the years they arose have been deferred and are being amortized to income over the useful lives of the properties in accordance with regulatory treatmenttreatment. See Note 32 – Regulatory Matters for additional information.


DP&LAES Ohio files U.S. federal income tax returnsas part of the consolidated U.S. income tax return filed by AES. The consolidated tax liability is allocated to each subsidiary based on the separate return method which is specified in our tax allocation agreement and which provides a consistent, systematic and rational approachapproach. See Note 87 – Income Taxes for additional information.

Financial Instruments
Our Master Trust investments in debt and equity financial instruments of publicly traded entities are classified as equity investments. These equity securities are carried at fair value and unrealized gains and losses on these securities are recorded in Other income. As these financial instruments are held to be used for the benefit of employees participating in employee benefit plans and are not used for general operating purposes, they are classified as non-current in Other deferred assets on the Consolidated Balance Sheets.


Held-for-sale Businesses
A business classified as held-for-sale is reflected on the balance sheet at the lower of its carrying amount or estimated fair value less cost to sell. A loss is recognized if the carrying amount of the business exceeds its estimated fair value less cost to sell. This loss is limited to the carrying value of long-lived assets until the completion of the sale, at which point, any additional loss is recognized. If the fair value of the business subsequently exceeds the carrying amount while the business is still held-for-sale, any impairment expense previously recognized will be reversed up to the lower of the previously recognized expense or the subsequent excess.

Assets and liabilities related to a business classified as held-for-sale are segregated in the current balance sheet in the period in which the business is classified as held-for-sale. Assets and liabilities of held-for-sale businesses are classified as current when they are expected to be disposed of within twelve months. Transactions between the business held-for-sale and businesses that are expected to continue to exist after the disposal are not eliminated to appropriately reflect the continuing operations and balances held-for-sale. See Note 14 – Generation Separation for further information.

Discontinued Operations
Discontinued operations reporting occurs only when the disposal of a business or a group of assets represents a strategic shift that has (or will have) a major effect on our operations and financial results. We report financial results for discontinued operations separately from continuing operations to distinguish the financial impact of disposal transactions from ongoing operations. Prior period amounts in the statement of operations and balance sheet are retrospectively revised to reflect the businesses determined to be discontinued operations. The cash flows of businesses that are determined to be discontinued operations are included within the relevant categories within operating, investing and financing activities on the face of the Statements of Cash Flows.

Transactions between the businesses determined to be discontinued operations and businesses that are expected to continue to exist after the disposal are not eliminated to appropriately reflect the continuing operations and balances held-for-sale. The results of discontinued operations include any gain or loss recognized on closing or adjustment of the carrying amount to fair value. See Note 14 – Generation Separation for further information.

Generation Separation
With the transfer of DP&L's generation assets to an affiliate (see Note 14 – Generation Separation), DP&L's generation business is presented as a discontinued operation and the operating activities have been reclassified to "Discontinued operations" in the Statements of Operations for the years ended December 31, 2017 and 2016 and in the notes to the financial statements.

Accounting for Taxes Collected from Customers and Remitted to Governmental Authorities
DP&L collects certain excise taxes levied by state or local governments from its customers. DP&L’s excise taxes and certain other taxes are accounted for on a net basis and recorded as a reduction in revenues in the accompanying Statements of Operations. The amounts for the years ended December 31, 2018, 2017 and 2016 were $51.7 million, $49.4 million and $50.9 million, respectively.

Cash and Cash Equivalents
Cash and cash equivalents are stated at cost, which approximates fair value. All highly liquid short-term investments with original maturities of three months or less are considered cash equivalents.

Restricted Cash
Restricted cash includes cash which is restricted as to withdrawal or usage. The nature of the restrictions includes restrictions imposed by agreements related to deposits held as collateral and cash collected under the DMR which is restricted to pay debt obligations at DPL and DP&L and position DP&L to modernize and/or maintain its transmission and distribution infrastructure.

The following table provides a summary of cash, cash equivalents, and restricted cash amounts reported on the Balance Sheet that reconcile to the total of such amounts as shown on the Statements of Cash Flows:

Financial Derivatives
All derivatives are recognized as either assets or liabilities in the balance sheets and are measured at fair value. Changes in the fair value are recorded in earnings unless the derivative is designated as a cash flow hedge of a forecasted transaction.

We use interest rate hedges to manage the interest rate risk of our variable rate debt. We use cash flow hedge accounting when the hedge or a portion of the hedge is deemed to be highly effective, which results in changes in fair value being recorded within accumulated other comprehensive income, a component of shareholder’s equity. We have elected not to offset net derivative positions in the financial statements. Accordingly, we do not offset such derivative positions against the fair value of amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral under master netting agreements. See Note 6 – Derivative Instruments and Hedging Activities for additional information.

Insurance and Claims Costs
In addition to insurance obtained from third-party providers, MVIC, a wholly-owned captive subsidiary of DPL, provides insurance coverage solely to us and other DPL subsidiaries for workers’ compensation, general liability, and property damage on an ongoing basis. DP&L is responsible for claims costs below certain coverage thresholds of MVIC and third-party insurers for the insurance coverage noted above. DP&L has estimated liabilities for medical, life, disability, and other reserves for claims costs below certain coverage thresholds of third-party providers of approximately $4.3 million and $4.4 million at December 31, 2018 and 2017, respectively, within Other current liabilities and Other deferred credits on the balance sheets. The estimated liabilities for workers’ compensation, medical, life and disability costs at DP&L are actuarially determined using certain assumptions. There is uncertainty associated with these loss estimates, and actual results may differ from the estimates. Modification of these loss estimates based on experience and changed circumstances is reflected in the period in which the estimate is re-evaluated.

Pension and Postretirement Benefits
We recognize in our Balance Sheets an asset or liability reflecting the funded status of pension and other postretirement plans with current-year changes from actuarial gains or losses related to our regulated operations, that would otherwise be recognized in AOCI, recorded as a regulatory asset as this can be recovered through future rates. Such changes that are not related to our regulated operations are recognized in AOCI. All plan assets are recorded at fair value. We follow the measurement date provisions of the accounting guidance, which require a year-end measurement date of plan assets and obligations for all defined benefit plans.

We account for and disclose pension and postretirement benefits in accordance with the provisions of GAAP relating to the accounting for pension and other postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the plans. Consistent with the requirements of FASC 715, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans.

OctoberJanuary 1, 20182020.We elected to early-adopt this standard on a prospective basis, effective for fiscal year 2018. The adoption of this standard did not have ahad no material impacteffect on our financial statements.
2018-14, Compensation— Retirement Benefits — Defined Benefit Plans — General (Subtopic 715-20): Disclosure FrameworkThis standard modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans.
Transition method: retrospective.
Early adoption elected, January 1, 2018Impact limited to changes in financial statement disclosures.
2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit CostThis standard changes the presentation of non-service costs associated with defined benefit plans and updates the guidance so that only the service cost component will be eligible for capitalization.
Transition method: retrospective for presentation of non-service cost and prospective for the change in capitalization.
January 1, 2018For the years ended December 31, 2017 and 2016 we reclassified non-service pension costs from Operating expenses to Other expense of ($1.5) million and ($0.9) million, respectively.
2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)This standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows.
Transition method: retrospective.
January 1, 2018For the years ended December 31, 2017 and 2016, we reclassified from "Net cash used in investing activities" to "Net increase / (decrease) in cash, cash equivalents and restricted cash" $26.6 million and ($11.9) million, respectively.

Adoption of FASC Topic 606, "Revenue from Contracts with Customers"326, "Financial Instruments - Credit Losses"
107

Table of Contents
On January 1, 2018,2020, we adopted ASU 2014-09, "Revenue from Contracts with Customers",ASC 326 Financial Instruments - Credit Losses and its subsequent corresponding updates ("FASC 606"ASC 326"). The core principlenew 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 this standard isan 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 entity shall recognize revenueallowance on the balance sheet with a corresponding adjustment to depictearnings in the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. income statement.

We applied the modified retrospective method of adoption to those contracts which were not completed asfor ASC 326. Under this transition method, we applied the transition provisions starting at the date of January 1, 2018. Results for reporting periods beginning January 1, 2018 are presented under FASC 606, while prior period amounts were not adjusted and continue to be reportedadoption. The CECL model primarily impacts the calculation of our expected credit losses in accordance with our historic accounting under the previous revenue recognition standard. For contracts that were modified before January 1, 2018, we have not retrospectively restated the contracts for modifications. We instead reflected the aggregate effect of all modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price. We do not expect thegross customer trade accounts receivable. The adoption of ASC 326 and the new revenue standard toapplication of CECL on our trade accounts receivable did not have a material impact toon our net income on an ongoing basis.Financial Statements.



There was no cumulative effect to our January 1, 2018 Balance Sheet resulting from the adoption of FASC 606.

Leases (Topic 842)
See discussion of the ASU below.January 1, 2019. Early adoption is permitted.We will adopt the standard on January 1, 2019; see below for the evaluation of the impact of its adoption on our financial statements.


Adoption of FASC Topic 842, "Leases"
ASU 2016-02 and its subsequent corresponding updates require lessees to recognize assets and liabilities for most leases but recognize expenses in a manner similar to today’s accounting. For lessors, the guidance modifies the lease classification criteria and the accounting for sales-type and direct financing leases. The guidance also eliminates today’s real estate-specific provisions.

The standard must be adopted using a modified retrospective approach. The FASB has provided an optional transition method, which we have elected, that allows entities to continue to apply the guidance in FASC 840 Leases to the comparative periods presented in the year of adoption. Under this transition method, we will apply the transition provisions starting on January 1, 2019.

We have elected to apply a package of practical expedients that allow lessees and lessors not to reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases, and (3) whether initial direct costs for any expired or existing leases qualify for capitalization under FASC 842. These three practical expedients must be elected as a package and must be consistently applied to all leases. We have also elected to apply an optional transition practical expedient for land easements that allows an entity to

continue applying its current accounting policy for all land easements that exist before the standard’s effective date that were not previously accounted for under FASC 840.

We established a task force focused on the identification of contracts that would be under the scope of the new standard and on the assessment and measurement of the right-of-use assets and related liabilities. Additionally, the implementation team has been working on the configuration of a lease accounting tool that will support the implementation and the subsequent accounting. The implementation team has also evaluated changes to our business processes, systems and controls to support recognition and disclosure under the new standard.

Under FASC 842, it is expected that fewer contracts will contain a lease. However, due to the elimination of the real estate-specific guidance and changes to certain lessor classification criteria, more leases will qualify as sales-type leases and direct financing leases. Under these two models, a lessor will derecognize the asset and will recognize a lease receivable. According to FASC 842, the lease receivable includes the fair value of the plant after the contract period but does not include any variable payments such as margin on the sale of energy. Therefore, the lease receivable could be significantly different than the carrying amount of the underlying asset at lease commencement. In such circumstances, the difference between the initially recognized lease receivable and the carrying amount of the underlying asset is recognized as a gain/loss at lease commencement.

The adoption of FASC 842 did not have a material impact on our financial statements.

Note 32 – Regulatory Matters


Distribution Rate OrderAES Ohio ESP and SEET Proceedings, Comprehensive Settlement
On September 26, 2018 the PUCO issued the DRO establishing new base distribution rates for DP&L, which became effective OctoberOhio law requires utilities to file either an ESP or MRO plan to establish SSO rates. From November 1, 2018. The DRO2017 through December 18, 2019, AES Ohio operated pursuant to an approved without modification, a stipulation and recommendation previously filed by DP&L, along with various intervening parties and the PUCO staff. The DRO established a

revenue requirement of $248.0 million for DP&L's electric service base distribution rates which reflects an increase to distribution revenues of approximately $29.8 million per year. In addition to the increase in base distribution rates, and among other matters, the DRO provides for a return on equity of 9.999% and a cost of long-term debt of 4.8% and for the following items:

DIR– The DRO authorized DP&L to begin charging a Distribution Investment Rider ("DIR") set initially at $12.2 million annually, effective October 1, 2018. The DIR revenue requirement shall be updated quarterly and will increase as DP&L makes qualified investments in its distribution network, subject to annual revenue limits which increase each year; the revenue limit for 2019 is $22.0 million. The DIR will expire in November 2022 unless DP&L files a base distribution rate case on or before October 31, 2022, in which case the DIR will expire in November 2023.

Decoupling Rider – The DRO eliminated provisions in the existing decoupling rider which allowed DP&L to recover lost revenues resulting from the implementation of energy efficiency programs and replaced it with a revenue requirement that attempts to eliminate the impacts of weather and demand on DP&L’s revenues from residential and commercial distribution customers beginning January 1, 2019. As a result, in years with very mild weather and/or decreased demand, DP&L will be able to accrue a regulatory asset for recovery through the rider to normalize the revenues. Conversely, in periods of extreme temperatures or high demand for electricity, DP&L may record a liability for future reimbursement to customers. The rider also includes a one-time $3.7 million revenue requirement based on the increase in the number of DP&L’s residential and commercial customers from the rate case test year until September 30, 2018. Such amount was accrued and included in revenues in the third quarter of 2018 and will be collected by DP&L in 2019.

TCJA – The DRO partially resolved the TCJA impacts. The new distribution rates include the impacts of the decrease in current federal income taxes beginning October 1, 2018. The DRO did not designate how much DP&L may owe for any overcollection of taxes from January 1, 2018 through September 30, 2018, nor did it resolve any decrease in future rates related to amortization of excess accumulated deferred income taxes (“ADIT”). The DRO did, however, stipulate that DP&L must refund its customers an amount no less than $4.0 million per year for the first five years of the amortization period unless all balances owed are fully returned within the first five years. For more on the impacts of the TCJA, see below.

Vegetation Management Costs – The DRO authorizes DP&L to defer as a regulatory asset, with no carrying costs, annual expenses for vegetation management performed by third-party vendors. For calendar year 2018 annual expenses which are incremental to the baseline of $10.7 million can be deferred up to a $4.6 million cap. For calendar years 2019 and thereafter, annual expenses in excess of $15.7 million can be deferred up to a $4.6 million annual cap. Annual spending of less than the vegetation management baseline amounts will result in a reduction to the regulatory asset or creation of a regulatory liability. For 2018, DP&L accrued a regulatory asset for the maximum amount of $4.6 million based upon such provisions and spending above the baseline.

In December 2018, DP&L filed a Distribution Modernization Plan (“DMP”) with the PUCO proposing to invest $576.0 million in capital projects over the next 10 years. There are eight principal components of DP&L’s DMP: 1) Smart Meters, 2) Self-Healing Grid, 3) Customer Engagement, 4) Enhancing Sustainability and Embracing Innovation. 5) Telecommunications, 6) Physical and Cyber Security, 7) Governance and Analytics, and 8) Grid Modernization R&D.

ESP Order
On March 13, 2017, DP&L filed an amended stipulation to its 2017 ESP,plan, which was subject to approval by the PUCO. A final decision was issued by the PUCOinitially approved on October 20, 2017 modifying(ESP 3). On December 18, 2019, the PUCO approved AES Ohio's Notice of Withdrawal and adoptingreversion to its prior rate plan (ESP 1). Among other items, the amended stipulationPUCO Order approving the ESP 1 rate plan includes:

Reinstating the non-bypassable RSC Rider, which provides annual revenues of approximately $79.0 million;
Continuation of AES Ohio's Transmission Cost Recovery Rider, Storm Rider and recommendation. The six-year 2017 ESP establishes DP&L's framework for providing retail service on a going-forward basis including rate structures, non-bypassable charges and other specific rate recovery true-up mechanisms which include, but are not limited to, the following:
Bypassablebypassable standard offer energy ratesrate for DP&L’sAES Ohio's customers based on competitive bid auctions;
and
A placeholder rider to recover grid modernization costs, called the Infrastructure Investment Rider.
The establishment
Separate from the ESP process, AES Ohio filed a petition seeking recovery of ongoing OVEC costs through a three-year non-bypassable Distribution ModernizationLegacy Generation Rider (DMR) designedand was granted approval effective January 1, 2020.

On October 23, 2020, AES Ohio entered into a Stipulation and Recommendation (the Settlement) with the staff of the PUCO and various customers, and organizations representing customers of AES Ohio and certain other parties with respect to, collect $105.0 million in revenue per year to pay debt obligationsamong other matters, AES Ohio's applications pending at DPL and DP&L and position DP&Lthe PUCO for (i) approval of AES Ohio's plan to modernize and/or maintain its transmissiondistribution grid (the Smart Grid Plan), (ii) findings that DP&L passed the SEET for 2018 and distribution infrastructure with an option2019, and (iii) findings that AES Ohio's current ESP 1 satisfies the SEET and the more favorable in the aggregate (MFA) regulatory test. A hearing was held in January 2021 for DP&L to fileconsideration of this settlement and on June 16, 2021, the PUCO issued their opinion and order accepting the stipulation as filed. Several applications for an extensionrehearing of the riderPUCO's orders relating to the Settlement were filed and denied on December 1, 2021. The OCC appealed this final PUCO Order to the Ohio Supreme Court on December 6, 2021; this appeal remains pending.

The settlement provides, among other items, for an additional two yearsthe following:

108

Approval of the Smart Grid Plan outlined in an amountthe Smart Grid Plan application filed by AES Ohio with the PUCO, as modified by the terms of the settlement, including, subject to approval by the PUCO.

Consistent with that settlementoffsetting operational benefits and the PUCO order,certain other conditions, a return on January 22, 2019, DP&L filed a requestand recovery of up to extend the DMR for the additional two years at an annual revenue amount$249.0 million of $199.0 million. That request is pending PUCO review;
The establishmentSmart Grid Plan Phase 1 capital investments and recovery of a non-bypassable Distributionoperational and maintenance expenses through AES Ohio's existing Infrastructure Investment Rider to recover incremental distribution capital investments,for a term of four years, under an aggregate cap of $267.6 million on the amount of such investments and expenses that is recoverable, and an acknowledgement that AES Ohio may file a subsequent application with the PUCO within three years seeking approvals for Phase 2 of the Smart Grid Plan;
A commitment by AES Ohio to invest in a customer information system and supporting technologies during Phase 1 of the Smart Grid Plan, with AES Ohio recovering a return on and of prudently incurred capital investments and operational and maintenance expenses, including deferred operational and maintenance expense amounts, in a future rate case;
Determinations that AES Ohio’s ESP 1 satisfies the prospective SEET and the MFA regulatory test and that AES Ohio satisfies the retroactive SEET for 2018 and 2019.
A commitment by AES Ohio to file an application with the PUCO no later than October 1, 2023 for a new electric security plan that does not seek to implement certain non-bypassable charges, including those related to provider of last resort risks, stability, or financial integrity; and
AES Ohio shareholder funding, in an aggregate amount of approximately $30.0 million over four years, for certain economic development discounts, incentives, and grants to certain commercial and industrial customers, including hospitals and manufacturers, assistance for low-income customers as well as the residents and businesses of the City of Dayton, and promotion of solar and resiliency development within AES Ohio's service territory.

Certain parties which was establishedintervened in the DP&L DRO;
A non-bypassable Reconciliation Rider permitting DP&LESP proceedings have filed petitions for rehearing of the recent PUCO ESP orders; some of which seek to defer, recover or credit the net proceeds from selling energy and capacity received as part of DP&L’s investment in OVEC and DP&L's OVEC related costs;
Implementation by DP&L of a Smart Grid Rider, Economic Development Rider, Economic Development Fund, Regulatory Compliance Rider and certain other new, or changes to existing, rates, riders and competitive retail market enhancements, with tariffs consistent with the order. These riders became effective November 1, 2017;
A commitment to commence a sale process to sell our ownership interests in the Miami Fort, Zimmer and Conesville coal-fired generation plants, with all sales proceeds used to pay debt of DPL and DP&L;
Restrictions on DPL making dividend or tax sharing payments and an obligation to convert then existing tax payments owed by DPL to eliminate AES into equity investments in DPL. See ; Note 8 – Income Taxes and Note 10 – Equity for more information on the tax sharing payment restrictions; and
Various other riders and competitive retail market enhancements.

On October 19, 2018 IGS, a retail electricity supplier, filed a Notice of WithdrawalOhio's RSC from the amended settlement, citing a material modification byESP 1 rates that are currently in place and others seek to re-implement ESP 3, but without the PUCO's October 2017 order. To addressDMR. We are unable to predict the withdrawal, the PUCO established a new procedural schedule, including a hearing currently scheduled to begin April 1, 2019. Additionally, on January 7, 2019, the Ohio Consumers' Counsel appealed the 2017outcomes of these petitions, but if these result in terms that are more adverse than AES Ohio's current ESP Order to the Supreme Court of Ohio. That appeal is pending.

DP&L is subject to a SEET threshold and is required to apply general rules for calculating earnings and comparing them to a comparable group to determine whether there were significantly excessive earnings during a given calendar year. The 2017 ESP maintains DP&L’s return on equity SEET threshold at 12% and provides that DMR amounts are excluded from the SEET calculation. On October 22, 2018, a stipulation was reached agreeing that DP&L did not exceed the SEET threshold for 2016 or 2017. That stipulation is pending PUCO approval. In future years, the SEETrate plan, it could have a material adverse effect on our results of operations, financial condition and cash flows.


ImpactConsistent with AES' earlier statement of Tax Reformintent, with the PUCO's issuance of their opinion and order, during 2021 DPL received $150.0 million from AES and, in turn, DPL made a capital contribution of $150.0 million to AES Ohio to enable AES Ohio to seek to improve its infrastructure and modernize its grid while maintaining liquidity.

Decoupling
On January 10, 201823, 2021 AES Ohio filed with the PUCO initiated a proceedingrequesting approval to considerdefer its decoupling costs consistent with the methodology approved in its Distribution Rate Case. An evidentiary hearing was held in May 2021. 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.

COVID-19
In response to the TCJAPUCO’s COVID-19 emergency orders, AES Ohio filed an Application on March 23, 2020, requesting waivers of certain rule and tariff requirements and deferral of certain costs and revenues including those related to determinedeposits 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 appropriate coursePUCO approved the application and required AES Ohio to file a plan outlining the timing and steps it plans to take in an effort to return to normal operations. The authorized deferral of action to pass benefits resulting fromthose certain costs and revenues must be offset by COVID-19 related savings. AES Ohio filed its plan on July 15, 2020 and was approved by the legislationPUCO on to ratepayers. The PUCO also directedAugust 12, 2020. As a result, AES Ohio utilities to record deferred liabilities for the estimated reduction has recorded a $0.9 million and $1.2 million regulatory asset as of December 31, 2021 and 2020, respectively. Recovery of these deferrals will be addressed in federal income tax resulting from the TCJA beginning January 1, 2018. Under the terms of the ESP, DPL will not make tax sharing payments. Under the terms of the stipulation in thea future rate proceeding.

Distribution Rate Case
On November 30, 2020, AES Ohio filed a new distribution rate case mentioned above, DP&L agreed to file an application atwith the PUCOPUCO. 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 March 1, 2019 to refund eligible excess accumulated deferred income taxes (ADIT)the tornados that occurred on Memorial Day in 2019. The rate case also includes a proposal for increased tree-trimming expenses and any relatedcertain customer demand-side management programs and recovery of prior-approved regulatory liability overassets for tree trimming, uncollectible expenses and rate case expense. A hearing on this case was held in January 2022, and the case is pending a 10-year period. Excess ADIT related to depreciation life and method differences will be returned to customers in accordance with federal tax law and related regulations. DP&L’s rates were set using the new tax rate as a resultcommission order.

FERC Proceedings
On May 8, 2018, DP&LMarch 3, 2020, AES Ohio filed an application before the FERC seeking to adjustchange its FERC jurisdictionalexisting stated transmission rates to reflectformula transmission rates that would be updated each calendar year. This filing was approved and made effective as of May 3, 2020, subject to possible refunds if the effectsapproved rates were modified. An uncontested settlement was filed December 10, 2020 and approved April 15, 2021. Among other things, the settlement established new depreciation rates for AES Ohio’s transmission assets and an authorized return on equity of 9.85%, and started an amortization process to return excess deferred taxes created by the TCJA. Because the approved settlement rates were lower than the proposed rates that went into effect, AES Ohio has accrued and/or paid refunds of approximately $4.4 million to users of the decrease in federal income tax ratestransmission system through December 31, 2021 through credits on the current portion of income tax expense as part of the TCJA, resulting in a decrease of approximately $2.4 million annually. The revised rates are in effect and all DP&L over and undercollections dating backPJM bills. Pursuant to the March 21stapproved mechanisms and formula, transmission rates were adjusted, effective date were settledon January 1, 2022, to reflect projected 2022 costs, adjusted to true-up the projections of revenues and costs incurred during 2020. Adjustments to true-up 2021 revenues and costs will be reflected in December 2018.

On November 15, 2018 FERC issued a Notice of Proposed Rulemaking to address amortization of excess accumulated deferred income taxes resulting from the TCJA and their impact on2023 formula transmission rates. Such notice requires all public utility transmission providersAt December 31, 2021, AES Ohio has recorded a liability of $12.6 million, with stated transmission rates under an Open Access Transmission Tariff (OATT)$0.4 million classified as current, representing credits owed to determinecustomers for the amount of excess deferred income taxes caused by the TCJA. DP&L is unable to predict the outcome of this notice or the impact it may have on our Financial Statements2020 and 2021 annual true-ups.


PJM Transmission Enhancement Settlement
On May 31, 2018, the FERC issued an Order on Contested Settlement regarding the cost allocation method for existing and new transmission facilities contained in the PJM Interconnection’s OATT. The FERC order approved the settlement which reduces DP&L’sAES Ohio’s transmission costs through PJM beginning in August 2018, including credits

to reimburse DP&LAES Ohio for amounts overcharged in prior years. DP&LAES Ohio estimates the prior overcharge by PJM to be $41.6$40.6 million, of which approximately $14.3$33.8 million has been repaid to DP&LAES Ohio through December 31, 20182021 and $16.5$1.7 million is classified as current in "Accounts receivable, net" and $10.8$5.1 million is classified as non-current in "Other deferrednon-current assets" on the accompanying Balance Sheet. All of the transmission charges and credits impacted by this FERC order are items that are included for full recovery in DP&L’s nonbypassableAES Ohio’s non-bypassable TCRR. Accordingly, DP&LAES Ohio has also established offsetting regulatory liabilities. While this development will have a temporary cash flow benefit to DP&LAES Ohio, there is no impact to operating income or net income as all credits will be passed to DP&L’sAES Ohio’s customers through the TCRR, which began in November 2018.


Regulatory Assets and Liabilities

Current regulatory assets and liabilities primarily represent costs that are being recovered per specific rate order; recovery for the remaining costs is probable, but not certain. DP&L is earning a net return on $5.5 million of this net deferral. These items include undercollection of:costs include: (i) Distribution Modernizationthe Energy Efficiency Rider, revenues, (ii) decoupling rider (see above),the Alternative Energy Rider, (iii) uncollectible riderthe Competitive Bidding Rider and (iv) energy efficiency rider. It also includesthe Transmission Cost Recovery Rider. Also included are the current portion of rate case expense costs, storm costs, Smart Grid O&M and Smart Grid R&D, which do not earn a return and are described in greater detail below. Current regulatory liabilities include the overcollection of economic development costs, legacy generation costs and certain transmission related costs, including the current portion of the following deferred costs which are described in greater detail below: unbilled fuel, regulatory compliance rider costs and deferred storm costs. As current liabilities, this includes overcollection of: (i) competitive bidding energy and auction costs, (ii) energy efficiency program costs, (iii) alternative energy rider, (iv) economic development rider, (v) certain transmission related costs including current portion of PJM transmission enhancement settlement, the transmission rate true-up and the TCJA regulatory liability (see above).

AES Ohio is earning a return on $8.1 million of this net current deferral including: (i) the Energy Efficiency Rider, (ii) the Alternative Energy Rider, (iii) the Competitive Bidding Rider and (vi) reconciliation rider.(iv) the Transmission Cost Recovery Rider. These regulatory assets are partially offset by the overcollection of economic development costs and legacy generation costs.



Pension benefits represent the qualifying FASC 715 “Compensation - Retirement Benefits” costs of our regulated operations that for ratemaking purposes are deferred for future recovery. We recognize an asset for a plan’s

overfunded status or a liability for a plan’s underfunded status, and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. This regulatory asset represents the regulated portion that would otherwise be charged as a loss to OCI. As per PUCO and FERC precedents, these costs are probable of future rate recovery.


Unrecovered OVEC charges includes the portion of charges from OVEC that were not recoverable through DP&L’s fuel riderAES Ohio’s Fuel Rider from October 2014 through October 2017. DP&LAdditionally, it includes net OVEC costs from December 19, 2019 through December 31, 2019. AES Ohio expects to recover these costs through a future rate proceeding. Beginning on November 1, 2017, suchthrough December 18, 2019, current OVEC costs arewere being recovered through DP&L’s Reconciliation RiderAES Ohio’s reconciliation rider which was authorized as part of the 2017 ESP.ESP 3. Beginning January 1, 2020, AES Ohio began recovering its current net OVEC costs through its Legacy Generation Rider, established pursuant to ORC 4928.148.


Fuel costs represent unrecovered fuel costs related to DP&L’s fuel rider from 2010 through 2015 resulting from a declining SSO customer base. DP&L was granted recovery of these costs without a return through the SSO as approved in the 2017 ESP. These costs are being recovered over the three-year period that began November 1, 2017.

Regulatory compliance rider representscosts represent the long-term portion of the regulatory compliance ridercosts which was established by the 2017 ESP to recoverinclude the following costs: (i) Consumer Education Campaign, (ii) Retail Settlement System, (iii) Generation Separation, (iv) Bill Format Redesign, (v) Green Pricing Tariff and (vi) Supplier Consolidated Billing. All of these costs except for Generation Separation earn a return. These costs arewere being recovered over a three-year period.period that began November 1, 2017 through a rider approved in the ESP 3. That rider was eliminated with the approval of the ESP 1 rate plan, so the balance as of December 18, 2019 remains a regulatory asset for future recovery.


Rate case costsexpenses represents costs associated with preparing a distribution rate case. DP&Lcases. AES Ohio was granted recovery of these costs for the 2015 case which do not earn a return, as part of the DRO. Recovery of costs for the 2020 case were included in the pending filing.


Smart Grid and AMI costs represent costs incurred as a result of studying and developing distribution system upgrades and implementation of AMI. On October 19, 2010, DP&L elected to withdraw its case pertaining to the Smart Grid and AMI programs. TheIn a PUCO accepted the withdrawal in an order issued on January 5, 2011. The2011, the PUCO also indicated that it expects DP&LAES Ohio to continue to monitor other utilities’ Smart Grid and AMI programs and to explore the potential benefits of investing in the Smart Grid Plan and AMI programs and that DP&LAES Ohio will, when appropriate, file new Smart Grid and/or AMI business cases in the future. DP&L requested recovery of theseThese costs as part ofare included in the December 2018 DMP filing with the PUCOOctober 23, 2020 settlement described earlier.above.


Unamortized loss on reacquired debt represents losses on long-term debt reacquired or redeemed in prior periods that have been deferred. These deferred losses are being amortized over the lives of the original issues in accordance with the rules of the FERC and the PUCO.


Deferred storm costs represent the long-term portion of deferred costs for major storms which occurred during 20172019, 2020 and 2018. The 2017 ESP granted DP&L approval to establish a rider by which to seek recovery of these types of costs with a return. DP&L2021. AES Ohio plans to file petitions seeking recovery of each calendar year of storm costs in the following calendar year.costs. Recovery of these costs is probable, by 2020, but not certain.


Vegetation management costs represents costs incurred from outside contractors for tree trimming and other vegetation management services. Calculation terms were agreed to in the stipulation approved in the DRO. The terms were an annual baseline of $10.7 million in 2018 and $15.7 million thereafter. Amounts over the baseline will be deferred subject to an annual deferral maximum of $4.6 million. Annual spending less than the vegetation management baseline amount will result in a reduction to the regulatory asset or creation of a regulatory liability. These costs are included in AES Ohio's pending distribution rate case application.

Decoupling deferral represents the change in the revenue requirement based on a per customer methodology in the stipulation approved in the DRO and includes deferrals through December 18, 2019. These costs were previously recovered through a Decoupling Rider; however, AES Ohio withdrew its application in the ESP 3 and in doing so, the PUCO ordered on December 18, 2019 in the ESP 1 order, that AES Ohio no longer has a Decoupling Rider. As described above, AES Ohio filed a petition seeking authority to record a regulatory asset to accrue revenues that would have otherwise been collected through the Decoupling Rider.

Uncollectible deferral represents deferred uncollectible expense associated with the nonpayment of electric service, less the revenues associated with the bypassable uncollectible portion of the standard offer rate. The DRO established that these costs would be recovered in a rider outside of base rates, thus no uncollectible expense is included in base rates. These costs are included in our pending distribution rate case.

Estimated costs of removal - regulated property reflect an estimate of amounts collected in customer rates for costs that are expected to be incurred in the future to remove existing transmission and distribution property from service when the property is retired.


Deferred income taxes payable through rates represent deferred income tax liabilities recognized from the normalization of flow-through items as the result of taxes previously charged to customers. A deferred income tax asset or liability is created from a difference in income recognition between tax laws and accounting methods. As a regulated utility, DP&LAES Ohio includes in ratemaking the impacts of current income taxes and changes in deferred income tax liabilities or assets. On December 22, 2017, the TCJA was signed, which includes a provision to, among other things, reduce the federal corporate income tax rate to 21%, beginning January 1, 2018. As required by GAAP, on December 31, 2017, DP&L remeasured its deferred income tax assets and liabilities using the new expected tax rate. DP&L believes that the portion of the reduction in the net deferred tax liability which is related to deferred taxes considered in ratemaking will be used in future ratemaking to reduce jurisdictional retail rates. Accordingly, this liability reflects the estimated deferred taxes DP&LAES Ohio expects to return to customers in future periods.



TCJA regulatory liability represents the long-term portion of both protected and unprotected excess ADIT for both transmission and distribution portions, grossed up to reflect the revenue requirement. As a part of the DRO, AES Ohio agreed that savings from the TCJA attributable to distribution facilities, including the excess ADIT and the regulatory liability, constitute amounts that will be returned to customers. As a result of the TCJA and subsequent DRO, AES Ohio entered into a stipulation to resolve all remaining TCJA items related to its distribution rates, including a proposal to return no less than $4.0 million per year for the first five years unless fully returned in the first five years via a tax savings cost rider for the distribution portion of the balance. On September 26, 2019, an order approved the stipulation in its entirety.

Transmission Formula Rate Credits liability represents the amounts due to customers as a result of the implementation of transmission formula rates, which are adjusted each year based on actual revenue and costs from a previous year, as described above under FERC Proceedings.

PJM Transmission Enhancement Settlement liability represents the Transmission Enhancement Settlement charges for which AES Ohio is due a refund per FERC Order EL05-121-009 issued on May 31, 2018. The Order states that customers are due a refund for part of these charges which will be received starting August 2018 through 2025. Refunds received will be returned to customers via the transmission cost rider.

Postretirement benefits represent the qualifying FASC 715 “Compensation – Retirement Benefits” gains related to our regulated operations that, for ratemaking purposes, are probable of being reflected in future rates. We recognize an asset for a plan’s overfunded status or a liability for a plan’s underfunded status, and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. This regulatory liability represents the regulated portion that would otherwise be reflected as a gain to OCI.

In June 2018, DP&L closed on a transmission asset transaction with Duke and AEP, where ownership stakes in certain previously co-owned transmission assets were exchanged to eliminate co-ownership. Each previously co-owned transmission asset became wholly-owned by one of DP&L, Duke or AEP after the transaction. This transaction also resulted in cash proceeds to DP&L of $10.6 million.


AROs
We recognizerecognized AROs in accordance with GAAP which requires legal obligations associated with the retirement of long-lived assets to be recognized at their fair value at the time those obligations are incurred. Upon initial recognition of a legal liability, costs are capitalized as part of the related long-lived asset and depreciated over the useful life of the related asset. Our legal obligations were associated with the retirement of our long-lived assets, consisting primarily of asbestos abatement and ash disposal facilities.

Note 54 – Fair Value


The fair values of our financial instruments are based on published sources for pricing when possible. We rely on valuation models only when no other method is available to us. The fair value of our financial instruments represents estimates of possible value that may or may not be realized in the future.


The table below presents the fair value and cost of our non-derivative instruments at December 31, 20182021 and 2017.2020. See also Note 65 – Derivative Instruments and Hedging Activities for the fair values of our derivative instruments.

Fair Value Hierarchy
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. These inputs are then categorized as:
Level 1 (quoted prices in active markets for identical assets or liabilities);
114

Table of Contents
Level 2 (observable inputs such as quoted prices for similar assets or liabilities or quoted prices in markets that are not active); or
Level 3 (unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability).


Valuations of assets and liabilities reflect the value of the instrument including the values associated with counterparty risk. We include our own credit risk and our counterparty’s credit risk in our calculation of fair value using global average default rates based on an annual study conducted by a large rating agency.


We did not have any transfers of the fair values of our financial instruments among Level 1, Level 2 or Level 3 of the fair value hierarchy during the years ended December 31, 20182021 and 2017.2020.



Debt
The fair value of debt is based on current public market prices for disclosure purposes only. Unrealized gains or losses are not recognized in the financial statements as debt is presented at the carrying value, net of unamortized premium or discount, in the financial statements. The debt amounts include the current portion payable in the next twelve months and have maturities that range from 20202040 to 2061.


Master Trust Assets
DP&LAES Ohio established a Master Trust to hold assets that could be used for the benefit of employees participating in employee benefit plans and these assets are not used for general operating purposes. ASU 2016-01 “Recognition and Measurement of Financial Assets and Financial Liabilities” was effective as of January 1, 2018. This ASU requires the change in the fair value of equity instruments to be recorded in income rather than in OCI. Equity Instruments were defined to include all mutual funds, regardless of the underlying investments. Therefore, as of January 1, 2018, AOCI of $1.7 million ($1.1 million net of tax) was reversed to Accumulated Deficit and all future changes to fair value on the Master Trust Assets will be included in income in the period that the changes occur. These changes to fair value were not material for the year ended December 31, 2018. These assets are primarily comprised of open-ended mutual funds, which are valued using the net asset value per unit. These investments are recorded at fair value within Other deferrednon-current assets on the consolidated balance sheets and classified as available for sale.

Duringequity securities. Gains and losses on these assets were not material during the yearyears ended December 31, 2018, $0.5 million ($0.4 million after tax) of various investments were sold to facilitate the distribution of benefits.2021, 2020 or 2019.


The fair value of assets and liabilities at December 31, 20182021 and 20172020 and the respective category within the fair value hierarchy for DP&LAES Ohio was determined as follows:

(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, fair value is assumed to equal carrying value.

Table of Contents
These 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.


Non-recurring Fair Value Measurements
We use the cost approach to determine the fair value of our AROs, which are estimated by discounting expected cash outflows to their present value at the initial recording of the liability. Cash outflows are based on the approximate future disposal cost as determined by market information, historical information or other management estimates. These inputs to the fair value of the AROs would be considered Level 3 inputs under the fair value hierarchy. The balance of AROs was $4.7 million and $8.0 million at December 31, 2018 and 2017, respectively.

Note 65 – Derivative Instruments and Hedging Activities


In the normal course of business, DP&L entersAES Ohio previously entered into various financial instruments, including derivative financial instruments. We useused 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 of our derivative instruments arewere used for risk management purposes and arewere designated as cash flow hedges if they qualifyqualified under FASC 815 for accounting purposes.


DP&L's interest rate swaps are designated as a cash flow hedge. At December 31, 2018 and 2017,In August 2020, the principal balance of the interest rate hedges was $140.0 million and $200.0 million, respectively.

Cash Flow Hedges
As part of our risk management processes, we identify 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. The effective portion of the hedging transaction is recognized in AOCI and transferred to earnings using specific identification of each contract when the forecasted hedged transaction takes place or when the forecasted hedged transaction is probable of not occurring. The ineffective portion of the cash flow hedge is recognized in earnings in the current period. All risk components were considered to determine the hedge effectiveness of the cash flow hedges. With the adoption of ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted improvements to Accounting for Hedging Activities effective January 1, 2019, we will no longer be required to calculate effectiveness and thus the entire change in the fair value of a hedging instrument will be 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.

We have two2 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 have a combined notional amount of $140.0 million and will settle monthly based on a one-month LIBOR. As of December 31, 2017, the interest rate swaps had a combined notional amount of $200.0 million. On March 29, 2018, we$140.0 million and settled $60.0 million of these interest rate swaps due to the partial repayment of the underlying debt andmonthly based on a gain of $0.8 million was recorded as a reduction to interest expense. Since the swap was partially settled, the remaining swaps were de-designated and then re-designated with a new hypothetical derivative.one-month LIBOR. The AOCIAOCL associated with the remaining swaps will bewas amortized out of AOCIAOCL into interest expense over the remaining life of the underlying debt.


We useused the income approach to value the swaps, which consists of forecasting future cash flows based on
contractual notional amounts and applicable and available market data as of the valuation date. The most common market data inputs used in the income approach include volatilities, spot and forward benchmark interest rates (LIBOR). Forward rates with the same tenor as the derivative instrument being valued are generally obtained from published sources, with these forward rates being assessed quarterly at a portfolio-level for reasonableness versus comparable published rates. We reclassifyreclassified gains and losses on the swaps out of AOCIAOCL and into earnings in those periods in which hedged interest payments occur.occurred.

Revolving Credit Agreement
At December 31, 2021 and 2020 the AES Ohio Credit Agreement had outstanding borrowings of $0.0 million and $20.0 million, respectively.

Significant Transactions
On JanuaryJuly 31, 2020, AES Ohio issued $140.0 million of First Mortgage Bonds and on August 3, 2018, DP&L and its lenders amended DP&L's Term Loan B credit agreement. The amendment (a) modified2020 used the definition of "applicable rate", from 2.25% per annumproceeds to 1.00% per annum - inpurchase at par value the case of the Base Rate, and from 3.25% per annum to 2.00% per annum - in the case of the Eurodollar Rate, and (b) included a "call protection" provision which stated that in the event the loan was repriced or any portion of the loans were prepaid, repaid, refinanced, substituted, or replaced on or prior July 3, 2018, such prepayment, acceleration, repayment, refinancing, substitution or replacement would be made at 101% of the principal amount so prepaid, repaid, refinanced, substituted or replaced. After July 3, 2018 any such transaction would occur at 100% of the principal amount of the then outstanding loans. There were no such transactions prior to July 3, 2018.

On March 30, 2018, DP&L commenced a redemption of $60.0$140.0 million of outstanding tax exempttax-exempt Ohio Air Quality Development Authority (OAQDA) Collateralized Pollution Control Revenue Refunding Bonds that had been issued in 2015. The new First Mortgage Bonds due 2020carry an interest rate of 3.20% and mature on July 31, 2040. The OAQDA Revenue bonds have not been legally cancelled and can be re-issued at par value (plus accrued and unpaid interest).the discretion of AES Ohio at any time. These bonds were redeemed at par plus accrued interest on April 30, 2018 with cash on hand.will be held in trust while we continue to evaluate market conditions and explore suitable long-term financing alternatives. Accordingly, as of December 31, 2021 and 2020, the $140.0 million variable rate OAQDA Revenue bonds are not treated as being outstanding in the Balance Sheets.


Debt Covenants and Restrictions
DP&L’s AES Ohio'sunsecured revolving credit agreementfacility and Bond Purchase and Covenants Agreement (financing document entered into in connection with the saleissuance of $200.0 million of variable rate tax-exemptAES Ohio's First Mortgage Bonds, dated as of August 1, 2015) have twoon July 31, 2020) has one financial covenants.covenant. The firstcovenant measures Total Debt to Total Capitalization and is calculated, at the end of each fiscal quarter, by dividing total debt at the end of the quarter by total capitalization at the end of the quarter. DP&L’s AES Ohio’s Total Debt to Total Capitalization ratio shall not be greater than 0.65 to 1.00; except that, the ratio shall be suspended if DP&L’s long-term indebtedness is less than or equal to $750.0 million. Additionally, the ratio shall be suspended any time after separation during which DP&L maintains a rating of BBB- (or in the case of Moody’s Investors Service, Inc. Baa3) or higher with a stable outlook from at least one of Fitch Investors Service Inc., Standard & Poor’s Ratings Services or Moody’s Investors Service, Inc. As of December 31, 2018, DP&L's ratings meet those requirements and this ratio is suspended for the quarter ended December 31, 2018.

The second financial covenant measures EBITDA to Interest Expense. The TotalConsolidated EBITDA to Consolidated Interest Charges ratio is calculated, at the end of each fiscal quarter, by dividing consolidated EBITDA for the four prior fiscal quarters by the consolidated interest charges for the same period. The ratio, per the agreement, is to be not less than 2.500.67 to 1.00. This financial covenant was met with a ratio of 8.09 to 1.00in compliance as of December 31, 2018.2021.

U.S. Tax Reform
On December 22, 2017, the U.S. enacted the TCJA. The TCJA significantly changes U.S. corporate income tax law.

In 2017, we recognized the income tax effects of the TCJA in accordance with Staff Accounting Bulletin No. 118 (“SAB 118”) which provides SEC guidance on the application of FASC 740, Income Taxes, in the reporting period in which the TCJA was signed into law. Accordingly, our 2017 financial statements reflected the income tax effects of U.S. tax reform for which the accounting was complete and provisional amounts for those impacts for which the accounting under FASC 740 was incomplete, but a reasonable estimate could be determined.

We completed our calculation of the impact of the TCJA in our income tax provision for the year ended December 31, 2018 in accordance with our understanding of the TCJA and guidance available as of the date of this filing. As a result of this remeasurement, certain deferred tax assets and liabilities related to regulated utility property of $17.0 million and $135.2 million at December 31, 2018 and 2017 were recorded as regulatory liabilities and were non-cash adjustments. These amounts result from the remeasurement of certain deferred tax assets and liabilities as the rates changed from 35% to 21%. Additionally, consistent with the provisions of SAB 118, in 2018 we finalized the remeasurement of deferred tax asset balances transferred to AES Ohio Generation as part of Generation Separation which resulted in an additional $10.0 million return of capital to DPL in 2018.

Uncertain Tax Positions
We apply the provisions of GAAP relating to the accounting for uncertainty in income taxes. A reconciliation of the beginning and ending amount of unrecognized tax benefits for DP&L is as follows:

Of the December 31, 2018The balance of unrecognized tax benefits $4.8was $0.4 million at December 31, 2021 and $1.4 million at December 31, 2020. Due to the closure of federal tax exams in 2021, the Company has reviewed its uncertain tax positions and determined that $1.0 million will not be sustained. Consequently, the $1.0 million of uncertain tax positions were reversed. The reversals did not affect the annual effective tax rate, but were reclassified to current tax payable. The total amount of remaining unrecognized tax benefits that would benefit the effective tax rate as of December 31, 2021 is due$0.4 million.

The amount anticipated to uncertaintyresult in a net decrease to unrecognized tax benefits within 12 months of December 31, 2021 is estimated to be $0.0 million.

Tax years subsequent to 2011 remain open to examination by taxing authorities. While it is often difficult to predict the final outcome or the timing of deductibility.resolution of any particular uncertain tax position, we believe we have appropriately accrued for our uncertain tax positions. However, audit outcomes and the timing of audit settlements and future events that would impact our previously recorded unrecognized tax benefits are subject to significant uncertainty. It is possible that the ultimate outcome of future examinations may exceed our provision for current unrecognized tax benefits.


We recognize interest and penalties related to unrecognized tax benefits in Income tax expense. The amounts accrued and the tax expense / (benefit) recorded were not material for each period presented.

None of the unrecognized tax benefits are expected to significantly increase or decrease within the next twelve months other than thosefor all subsequent periods. AES Ohio is no longer subject to expiring statute of limitations.state income tax examinations for tax years through 2017, but is open for all subsequent periods.



Note 98 – Benefit Plans


Defined Contribution Plans
DP&LAES Ohio sponsors two defined contribution plans. One is for non-union employees (the management plan) and one is for collective bargaining employees (the union plan). Both plans are qualified under Section 401 of the Internal Revenue Code.


Certain non-union and union employees become eligible to participate in their respective plan upon date of hire.


Participants may elect to contribute up to 85% of eligible compensation to their plan. Non-union participant contributions are matched 100% on the first 1% of eligible compensation and 50% on the next 5% of eligible compensation and they are fully vested in their employer contributions after 2 years of service. Union participant contributions are matched 150% but are capped at $2,400$2,650 for 20182021 and they are fully vested in their employer contributions after 3 years of service. All participants are fully vested in their own contributions.


We contributed $3.7$3.3 million, $3.1$3.2 million and $5.1$3.1 million for the years ended December 31, 2018, 20172021, 2020 and 2016,2019, respectively. DP&LAES Ohio matching contributions are paid quarterly,bi-weekly, in arrears. Therefore, theThe contributions by year may include the fourth quarterbi-weekly matching contribution that is paid in the following year. DP&Lyear in addition to employer matching true-up contributions. AES Ohio also contributes an annual bonus to the accounts of its union participants. This payment is typically made in January of the following year.


Defined Benefit Plans
DP&LAES Ohio sponsors a traditional defined benefit pension plan for most of the employees of DPL and its subsidiaries. For collective bargaining employees, the defined benefits are based on a specific dollar amount per year of service. For all other employees (management employees), the traditional defined benefit pension plan is based primarily on compensation and years of service. As of December 31, 2010, this traditional pension plan formula was closed to new management employees. A participant is 100% vested in all amounts credited to his or her account upon the completion of five vesting years, as defined in The Dayton Power and Light Company Retirement Income Plan, or the participant’s death or disability. If a participant’s employment is terminated, other than by death or disability, prior to such participant becoming 100% vested in his or her account, the account shall be forfeited as of the date of termination. Employees that transferred from DP&LAES Ohio to the Service Company maintain their previous eligibility to participate in the DP&LAES Ohio pension plan. In addition, employees that transferred from DP&L to AES Ohio Generation due to Generation Separation maintain their previous eligibility to participate in the DP&L pension plan.


Almost all management employees beginning employment on or after January 1, 2011 participate in a cash balance pension plan formula. Similar to the traditional pension plan for management employees, the cash balance benefits are based on compensation and years of service. A participant shall become 100% vested in all amounts credited to his or her account upon the completion of three vesting years, as defined in The Dayton Power and Light Company Retirement Income Plan, or the participant’s death or disability. If a participant’s employment is terminated, other than by death or disability, prior to such participant becoming 100% vested in his or her account, the account shall be forfeited as of the date of termination. Vested benefits in the cash balance plan are fully portable upon termination of employment.

In addition, we have a Supplemental Executive Retirement Plan (SERP) for certain retired key executives. The SERP has an immaterial unfunded liability related to agreements for retirement benefits of certain terminated and retired key executives. We also include our net liability to our partners in our co-owned generating plants related to our share of their pension liabilities within Pension, retiree and other benefits on our Balance Sheets.


We recognize an asset for a plan’s overfunded status and a liability for a plan’s underfunded status and recognize, as a component of OCI, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. For the transmission and distribution areas of our electric business, these amounts are recorded as regulatory assets and liabilities which represent the regulated portion that would otherwise be charged or credited to AOCI.AOCL. We have historically recorded these costs on the accrual basis, and this is how these costs have been historically recovered through customer rates. This factor, combined with the historical precedents from the PUCO and FERC, make these costs probable of future rate recovery.


Postretirement Benefits
Qualified employees who retired prior to 1987 and their dependents are eligible for health care and life insurance benefits until their death, while qualified employees who retired after 1987 are eligible for life insurance benefits and partially subsidized health care. The partially subsidized health care is at the election of the employee, who pays the majoritymost of the cost, and is available only from their retirement until they are covered by Medicare. 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 $9.2$8.9 million and $12.7$9.0 million at December 31, 20182021 and 2017,2020, respectively, were not material to the financial statements in the periods covered by this report.

Significant Gains and Losses Related to Changes in the Benefit Obligation
The actuarial gain of $34.6$12.7 million decreased the benefit obligation for the year ended December 31, 20182021 and an actuarial loss of $28.1$52.7 million increased the benefit obligation for the year ended December 31, 2017.2020. The actuarial gain in 20182021 was primarily due to an increase in the discount rate whileand the actuarial loss in 20172020 was primarily due to a decrease in the discount rate.


Assumptions
Our expected return on plan asset assumptions, used to determine benefit obligations, are based on historical long-term rates of return on investments, which use the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. Current market factors, such as inflation and interest rates, as well as asset diversification and portfolio rebalancing, are evaluated when long-term capital market assumptions are determined. Peer data and historical returns are reviewed to verify reasonableness and appropriateness.


At December 31, 2018,2021, we are maintainingincreasing our long-term rate of return assumption of 6.25%to 4.60% for pension plan assets. The rate of return represents our long-term assumptions based on our long-term portfolio mix. Also, at December 31, 2018,2021, we have increased our assumed discount rate to 4.35%2.83% from 3.66%2.44% for pension expense to reflect current duration-based yield curve discount rates. A one1 percent increase in the rate of return assumption for pension would result in a decrease in 20192022 pension expense of approximately $3.2$3.4 million. A one1 percent decrease in the rate of return assumption for pension would result in an increase in 20192022 pension expense of approximately $3.2$3.4 million. A 25-basis point increase in the discount rate for pension would result in a decrease of approximately $0.1$0.5 million to 20192022 pension expense. A 25-basis point decrease in the discount rate for pension would result in an increase of approximately $0.4$0.5 million to 20192022 pension expense.


In determining the discount rate to use for valuing liabilities, we used a market yield curve on high-quality fixed income investments as of December 31, 2018.2021. We project the expected benefit payments under the plan based on participant data and based on certain assumptions concerning mortality, retirement rates, termination rates, etc. The expected benefit payments for each year are then discounted back to the measurement date using the appropriate spot rate for each half-year from the yield curve, thereby obtaining a present value of all expected future benefit payments using the yield curve. Finally, an equivalent single discount rate is determined which produces a present value equal to the present value determined using the full yield curve.


Consistent with the requirements of FASC 715, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans.

In future periods, differences in the actual return on pension plan assets and assumed return, or changes in the discount rate, will affect the timing of contributions, if any, to the plans.


The weighted average assumptions used to determine benefit obligations at December 31, 2018, 20172021, 2020 and 20162019 were:

Pension Plan Assets
Plan assets are invested in multiple asset classes using a total return investment approach whereby a mix of equity securities, debt securitiesde-risking framework designed to manage the Plan's funded status volatility and other investments are used to preserve asset values, diversify risk and achieve our target investment return benchmark.minimize future cash contributions. Investment strategies and asset allocations are based on careful consideration of plan liabilities,intended to allocate additional assets to the plan'sfixed income asset class should the Plan's funded status improve and our financial condition.is therefore broadly described as the Dynamic De-risking Strategy. Investment performance and asset allocation are measured and monitored on an ongoing basis.


Plan assets are managed in a balanced portfolio comprised of two major components: an equity portionreturn seeking assets and a fixed income portion.liability hedging assets. The expected role of plan equity investmentsreturn seeking assets is to maximize the long-term real growthprovide additional return with associated higher levels of plan assets,risk, while the role of liability hedging assets is to correlate the interest rate of the fixed income investments is to generate current income, provide for more stable periodic returns and provide some protection against a prolonged decline inwith that of the market value of plan equity investments.Plan's liabilities.


Long-term strategic asset allocation guidelines, as well as short-term tacticalStrategic asset allocation guidelines are determined by a Risk/Advisory Committee and approved by a Fiduciary Committee. These allocations consider the plan’s long-term objectives. The long-term target allocations for plan assets are 24%40%52%50% for equity securitiesreturn seeking assets and 47%50%65%60% for fixed income securities. Equity securitiesliability hedging assets. Return seeking assets include U.S. and international equity, while fixed income securitiesliability hedging assets include long-duration and high-yield bond funds and emerging market debt funds.


Tactically,The investment approach is to move the committees, onPlan to a short-term basis, will make asset allocations that are outsidemore de-risked position, if and when the long-termoverall funded status of the Plan improves, by periodically rebalancing the allocation guidelines. The short-term allocation positions are likelyof the Plan's investments in growth assets and liability hedging assets in accordance with the committee's glide path. This strategy requires the daily monitoring of the Plan's ratio of assets to not exceed one-yearliabilities in duration. In additionorder to determine whether approved trigger points have been met, requiring the equity and fixed income investments,rebalancing of the short-term allocation may also include a relatively small allocation to alternative investments. The plan currently has a small target allocation in a core property fund.assets.

Pension Funding
We generally fund pension plan benefits as accrued in accordance with the minimum funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA) and, in addition, make voluntary contributions from time to time. We contributed $7.5$9.8 million to the pension plan in the year ended December 31, 20182021, and $5.0$7.5 million to the pension plan in each of the years ended December 31, 20172020 and 2016.2019.


We expect to make contributions of $0.4$0.2 million to our SERP in 20192022 to cover benefit payments. We also expect to make contributions of $7.5 million to our pension plan during 2019.2022.



Funding for the qualified Defined Benefit Pension Plan is based upon actuarially determined contributions that consider the amount deductible for income tax purposes and the minimum contribution required under ERISA, as amended by the Pension Protection Act of 2006, as well as targeted funding levels necessary to meet certain thresholds.


From an ERISA funding perspective, DP&L’sAES Ohio’s funded target liability percentage was estimated to be 101%114%. In addition, DP&LAES Ohio must also contribute the normal service cost earned by active participants during the plan year. The funding of normal cost is expected to be approximately $5.4$5.8 million in 2019,2022, which includes $1.9$1.7 million for plan expenses. Each year thereafter, if the plan’s underfunding increases to more than the present value of the remaining annual installments, the excess is separately amortized over a seven-year period. DP&L’sseven years. AES Ohio’s funding policy for the pension plans is to contribute annually no less than the minimum required by applicable law, and no more than the maximum amount that can be deducted for federal income tax purposes.

Note 1110 – Contractual Obligations, Commercial Commitments and Contingencies


DP&LAES Ohio – 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. At December 31, 2018, DP&L2021, AES Ohio could be responsible for the repayment of 4.9%, or $68.1$55.5 million, of a $1,389.6$1,131.7 million debt obligation comprised of both fixed and variable rate securities with maturities between 20192022 and 2040. OVEC could also seek additional contributions from us to avoid a default in the event that other OVEC members defaulted on their respective OVEC obligations. One of the other OVEC members, with a 4.85% interest in OVEC, filed for bankruptcy protection and the bankruptcy court approved that member's rejection of the OVEC arrangement and its related obligations on July 31, 2018. We do not expect these events to have a material impact on our financial condition, results of operations or cash flows.

Electricity purchase commitments:
DP&LAES Ohio enters into long-term contracts for the purchase of electricity. In general, these contracts are subject to variable quantities or prices and are terminable only in limited circumstances.


Purchase orders and other contractual obligations:
At December 31, 2018, DP&L2021, AES Ohio had various other contractual obligations including non-cancelable contracts to purchase goods and services with various terms and expiration dates. Due to uncertainty regarding the timing and payment of future obligations to the Service Company, and DP&L'sAES Ohio's ability to terminate such obligations upon 90 days' notice, we have excluded such amounts in the contractual obligations table aboveabove.


Contingencies
In the normal course of business, we are subject to various lawsuits, actions, proceedings, claims and other matters asserted under laws and regulations. We believe the amounts provided in our Financial Statements, as prescribed by GAAP, are adequate in light ofconsidering 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, including the matters discussed 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 as of December 31, 2018,2021, cannot be reasonably determined.

Environmental Matters
DP&L'sAES Ohio'sfacilities and operations are subject to a wide range of federal, state and local environmental laws, rules and regulations. The environmental issues that may affect us include the following. However, as described further below,following; however, as a result ofDPL’s retirement of its Stuart and Killen generating stations, the sale of its ownership interest in the Miami Fort and Zimmer generating stations, the planned 2020 retirement of Conesville and our exiting of our generation business, certain of these environmental regulations and lawsrequirements are now notno longer expected to have a material impact on DPL with respect toAES Ohio. See Item 1 - Business - Environmental Matters for a more comprehensive discussion of these generating stations.and other environmental matters impacting us.
The federal CAA and state laws and regulations (including SIPs) which require compliance, obtaining permits and reporting as to 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, theseenvironmental laws, rules 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 laws, rules and 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 a number of 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 or cash flows.



We have several pending environmental matters associated with our current and previously ownedpreviously-owned and operated coal-fired generation units. Some ofWe do not expect these matters couldto have a material adverse impactsimpact on our results of operations, financial condition or cash flows.

Note 1312 – 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 of promised goods or services 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.


Retail Revenues DP&Lrevenue
AES Ohio energy sales to utility customers are based on the reading of meters at the customer's location that occurs on a systematic basis throughout the month. DP&LAES Ohio sells electricity directly to end-users, such as homes and businesses, and bills customers directly. Performance obligations for retail revenues are satisfied over time as energy is delivered and the same method is used to measure progress, and thus the performance obligation meets the criteria to be considered a series. This includes both the promise to transfer energy and other distribution and/or transmission services.


In exchange for the exclusive right to sell or distribute electricity in our service area, DP&LAES Ohio is subject to rate regulation by federal and state regulators. This regulation sets the framework for the prices (“tariffs”) that DP&L AES Ohio is allowed to charge customers for electricity. Since tariffs are approved by the regulator, the price that DP&LAES Ohio has the right to bill corresponds directly with the value to the customer of DP&L'sAES Ohio's performance completed in each period. Therefore, revenue under these contracts is recognized using an output method measured by the MWhs delivered each month at the approved tariff.


In cases where a customer chooses to receive generation services from a CRES provider, the price for generation services is negotiated between the customer and the CRES provider, and DP&LAES Ohio only serves as a billing agent if requested by the CRES provider. As such, DP&LAES Ohio recognizes the consolidated billing arrangement with the
127

CRES provider on a net basis, thereby recording no revenue for the generation component. Retail revenue from these customers would only be related to transmission and distribution charges.


Wholesale RevenuesDP&L'srevenue
AES Ohio's share of the power produced at OVEC is sold to PJM and isthese revenues are classified as Wholesale revenues.


In PJM, the promise to sell energy as wholesale revenue is separately identifiable from participation in the capacity market and the two products can be transacted independently of one another. Therefore, wholesale revenues are a separate contract with a single performance obligation. Revenue is recorded based on the quantities (MWh) delivered in each hour during each month at the spot price, making the contract effectively “month-to-month”.


RTO Revenues ancillary revenue
Compensation for use of DP&L’sAES Ohio’s transmission assets and compensation for various ancillary services are classified as RTO ancillary revenues. As DP&LAES Ohio owns and operates transmission lines in southwest Ohio within PJM, demand charges collected from network customers by PJM are then allocated to the appropriate transmission owners (i.e. DP&LAES Ohio) and recognized as transmission revenues. Additionally, as an owner of generation and transmission assets within PJM, DPL is compensated for various ancillary services; such as reactive supply, regulation services, scheduling reserves, operating reserves, spinning/synchronized reserves as well as congestion credits that are provided to PJM via these assets.


Transmission revenues have a single performance obligation, as transmission services represent a distinct service. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The price that DP&LAES Ohio, as the transmission operator, has the right to bill (received as a credit from PJM) corresponds directly with the value to the customer of performance completed in each period, as the price paid is the allocation of the tariff rate (as approved by the regulator) charged to network participants.


RTO Capacity Revenues – Compensation received from PJM for making installed generationrevenue
AES Ohio records its share of OVEC capacity available to satisfy system integrityrevenues as Capacity revenues. The capacity price is set through a competitive auction process established by PJM. Depending on the availability and reliability requirements is classified as RTO capacity revenues. Capacity, which is a stand-ready obligation to deliver energy when called upon byperformance of the RTO, is measured using MWs. If plant availability exceeds a contractual target, weOVEC units, there may receive abe additional performance bonus payment, or if the plant availability falls below a guaranteed minimum target, we may incur a non-availability penalty. Such bonuses or penalties, represent a form of

variable consideration and are estimated andwhich would be recognized whenonly if it isbecomes probable that theresuch bonus or penalties will not be a significant reversal and therefore the transaction price is recognized on an output basis based on the MWs.incurred.


RTO capacity revenues have a single performance obligation, as capacity is a distinct good. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The capacity price is set through a competitive auction process established by PJM.

We have elected to apply the optional disclosure exemptions under FASC 606. Therefore, we have no disclosures pertaining to revenue expected to be recognized in any future year related to remaining performance obligations, as we exclude contracts with an original length of one year or less, contracts for which we recognize revenue based on the amount we have the right to invoice for services performed, and variable consideration allocated entirely to a wholly unsatisfied performance obligation when the consideration relates specifically to our efforts to satisfy the performance obligation and depicts the amount to which we expect to be entitled for DP&L.AES Ohio.


Note 14 – Generation Separation

On October 1, 2017, DP&L completed the transfer of its generating plants, the real property on which the generation plants and generation-related assets are sited, step-up transformers and other transmission plant assets used to interconnect with the electric transmission grid, fuel inventory, equipment inventory and spare parts, working capital, and other miscellaneous generation-related assets and liabilities to AES Ohio Generation. The transfer was completed as a contribution through an asset contribution agreement to a wholly-owned subsidiary of DP&L after which DP&L then distributed all of the outstanding equity in the subsidiary to DPL and then the subsidiary was merged into AES Ohio Generation.

Cash flows related to discontinued operations are included in the Statements of Cash Flows. Cash flows from operating activities for discontinued operations were $21.8 million and $29.9 million for the years ended December 31, 2017 and 2016, respectively. Cash flows from investing activities for discontinued operations were $(3.5) million and $(39.0) million for the years ended December 31, 2017 and 2016, respectively.

The PUCO authorized DP&L to maintain long-term debt of $750 million or 75% of its rate base, whichever is greater, until January 1, 2018, or to file an application to explain why it would not achieve those metrics. Accordingly, $750.0 million of debt and the pro rata interest expense associated with that debt were allocated to continuing operations. All remaining interest expense is included in discontinued operations above. The interest expense included in discontinued operations was $0.2 million and $0.5 million for the years ended December 31, 2017 and 2016, respectively.

Note 14 – Risks & Uncertainties

COVID-19 Pandemic

The COVID-19 pandemic has impacted global economic activity, including electricity and energy consumption, and caused significant volatility in financial markets. Many countries, including the U.S., reacted to the pandemic by instituting quarantines and mandating business and school closures or limitations and other social distancing measures. Responses to the COVID-19 pandemic by the State of Ohio and its residents and businesses continue to evolve as virus variants emerge, vaccine availability and usage continues and the state and businesses review and adjust the scope and requirements of social distancing measures. Social distancing measures designed to slow the spread of the virus, such as business closures and operations limitations, impact energy demand within our service
129

territory. We continue to take a variety of measures in response to the spread of COVID-19 to ensure our ability to generate, 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 the impacts to demand within our service territory, we also have incurred and expect to continue to incur expenses relating to COVID-19, including those that relate to events outside of our control. 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.

Item 9A – Controls and Procedures


Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the CEO and CFO, as appropriate, to allow timely decisions regarding required disclosures.


We carried out the evaluation required by Rules 13a-15(b) and 15d-15(b), under the supervision and with the participation of our management, including the CEO and CFO, of the effectiveness of our “disclosure controls and procedures” (as defined in the Exchange Act Rules 13a-15(e) and 15d-15(e)). Based upon this evaluation, our CEO and CFO concluded that as of December 31, 2018,2021, our disclosure controls and procedures were effective.


Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes those policies and procedures that:
pertain to the maintenance of records that in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and
provide reasonable assurance that unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements are prevented or detected timely.


Management, including our CEO and CFO, does not expect that our internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. In addition, any evaluation of the effectiveness of controls is subject to risks that those internal controls may become inadequate in future periods because of changes in business conditions, or that the degree of compliance with the policies or procedures deteriorates.


Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2018.2021. In making this assessment, management used the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in 2013. Based on this assessment, management believes that we maintained effective internal control over financial reporting as of December 31, 2018.2021.


Changes in Internal Control Over Financial Reporting:
There were no changes that occurred during the quarter ended December 31, 20182021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 14 – Principal Accountant Fees and Services
Accountant FeesThe Financial Audit Committee of AES pre-approves the audit and non-audit services provided by the independent auditors for itself and its subsidiaries, including DPL and its subsidiaries and AES Ohio. The AES Financial Audit Committee maintained its policy established in 2002 within which to judge if the independent auditor may be eligible to provide certain services outside of its main role as outside auditor. Services within the established framework include audit and related services and certain tax services. Services outside of the framework require AES Financial Audit Committee approval prior to the performance of the service. The Sarbanes-Oxley Act of 2002 addresses auditor independence and this framework is consistent with the provisions of the Act. No services performed by the independent auditor with respect to DPL and AES Ohio and its subsidiaries were approved after the fact by the AES Financial Audit Committee other than those that were considered to be de minimis and approved in accordance with Regulation 2-01(c)(7)(i)(C) to Regulation S-X of the Exchange Act.

In addition to the pre-approval policies of the AES Financial Audit Committee, the DPL and AES Ohio Boards of Directors will specifically approve the annual audit services and fees of the independent auditor and the taking of other related actions, such as entering into the terms of the engagement letter.

Audit fees are fees billed or expected to be billed by our principal accountant for professional services for the audit of the Financial Statements, included in DPL's and AES Ohio's annual report on Form 10-K and review of financial statements included in DPL's and AES Ohio's quarterly reports on Form 10-Q, services that are normally provided by our principal accountants in connection with statutory, regulatory or other filings or engagements or any other service performed to comply with generally accepted auditing standards and include comfort and consent letters in connection with SEC filings and financing transactions.
