Overview and Summary of Significant Accounting Policies

OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DPL is a regional energy company organized in 1985 under the laws of Ohio. DPL has one reportable segment, the Utility segment. See Note 9 – BUSINESS SEGMENTS for more information relating to this reportable segment. The terms “we,” “us,” “our” and “ours” are used to refer to DPL and its subsidiaries. DPL is an indirectly wholly-owned subsidiary of AES.

DP&L, a wholly-owned subsidiary of DPL that does business as AES Ohio, is a public utility incorporated in 1911 under the laws of Ohio. Beginning in 2001, Ohio law gave Ohio consumers the right to choose the electric generation supplier from whom they purchase retail generation service; however, retail transmission and distribution services are still regulated. AES Ohio has the exclusive right to provide such transmission and distribution services to approximately 535,000 customers located in West Central Ohio. Additionally, AES Ohio provides retail SSO electric service to residential, commercial, industrial and governmental customers in a 6,000-square mile area of West Central Ohio. AES Ohio sources all of the generation for its SSO customers through a competitive bid process. Principal industries located in AES Ohio’s service territory include automotive, food processing, paper, plastic, manufacturing and defense. AES Ohio's sales reflect the general economic conditions, seasonal weather patterns of the area, the market price of electricity and customer energy efficiency initiatives. AES Ohio owns numerous transmission facilities. AES Ohio sells its proportional share of energy and capacity from its investment in OVEC into the wholesale market.

DPL’s other primary subsidiaries are MVIC and Miami Valley Lighting. MVIC is our captive insurance company that provides insurance services to AES Ohio and our other subsidiaries, and Miami Valley Lighting provides street and outdoor lighting services to customers in the Dayton region. In prior periods, AES Ohio Generation was also a primary subsidiary and sold all of its energy and capacity into the wholesale market. AES Ohio Generation retired its only remaining operating asset in May 2020 and sold it in June 2020. See Note 11 – DISCONTINUED OPERATIONS for more information. DPL's subsidiaries are all 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.

AES Ohio’s electric transmission and distribution businesses are subject to rate regulation by federal and state regulators. Accordingly, AES 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.

Consolidation

DPL’s Condensed 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. Certain immaterial amounts from prior periods have been reclassified to conform to the current period presentation. All material intercompany accounts and transactions are eliminated in consolidation.

Interim Financial Presentation

The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASB ASC, for interim financial information and Article 10 of Regulation S-X issued by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income, changes in common shareholder's deficit, and cash flows. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of expected results for the year ending December 31, 2022. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2021 audited consolidated financial statements and notes thereto, which are included in our Form 10-K.

Use of Management Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions 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 and assumptions. Significant items subject to such estimates and assumptions include: recognition of revenue including unbilled revenues; the carrying value of property, plant and equipment; the valuation of insurance and claims liabilities; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; liabilities recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits.

Cash, Cash Equivalents and Restricted Cash

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

$ in millions	September 30, 2022		December 31, 2021
Cash and cash equivalents	$	44.3	$	26.6
Restricted cash (included in Prepayments and other current assets)	0.1		0.1
Cash, Cash Equivalents, and Restricted Cash, End of Period	$	44.4	$	26.7

Accounts Receivable and Allowance for Credit Losses

The following table summarizes accounts receivable as of September 30, 2022 and December 31, 2021:

	September 30,		December 31,
$ in millions	2022		2021
Accounts receivable, net:
Customer receivables	$	66.0	$	42.3
Unbilled revenue	15.0		19.2
Amounts due from affiliates	4.6		3.1
Due from PJM transmission enhancement settlement	1.7		1.7
Other	2.7		5.5
Allowance for credit losses	(0.4)		(0.3)
Total accounts receivable, net	$	89.6	$	71.5

The following table is a roll forward of our allowance for credit losses related to the accounts receivable balances for the nine months ended September 30, 2022 and 2021:

$ in millions	Beginning Allowance Balance		Current Period Provision		Write-offs Charged Against Allowances		Recoveries Collected		Ending Allowance Balance
2022	$	0.3	$	1.4	$	(2.1)	$	0.8	$	0.4
2021	$	2.8	$	(0.4)	$	(2.6)	$	1.1	$	0.9

The allowance for credit losses primarily relates to utility customer receivables, including unbilled amounts. Expected credit loss estimates are developed by disaggregating customers into those with similar credit risk characteristics and using historical credit loss experience. In addition, we also consider how current and future economic conditions are expected to impact collectability. Amounts are written off when reasonable collections efforts have been exhausted. During 2021, the current period provision and allowance for credit losses decreased due to lower past due customer receivable balances.

Inventories

Inventories consist of materials and supplies as of September 30, 2022 and December 31, 2021.
