Notes to Condensed Consolidated Financial Statements
For the Three Months Ended March 31, 2024 and 2023
(Unaudited)
1. FINANCIAL STATEMENT PRESENTATION
Consolidation — In this Quarterly Report, the terms “AES,” “the Company,” “us” or “we” refer to the consolidated entity, including its subsidiaries and affiliates. The terms “The AES Corporation” or “the Parent Company” refer only to the publicly held holding company, The AES Corporation, excluding its subsidiaries and affiliates. Furthermore, VIEs in which the Company has a variable interest have been consolidated where the Company is the primary beneficiary. Investments in which the Company has the ability to exercise significant influence, but not control, are accounted for using the equity method of accounting, except for our investment in Alto Maipo, for which we have elected the fair value option as permitted under ASC 825. All intercompany transactions and balances have been 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 equity, and cash flows. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of expected results for the year ending December 31, 2024. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2023 audited consolidated financial statements and notes thereto, which are included in the 2023 Form 10-K filed with the SEC on February 29, 2024 (the “2023 Form 10-K”).
Cash, Cash Equivalents, and Restricted Cash — The following table provides a summary of 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):
March 31, 2024December 31, 2023
Cash and cash equivalents$1,994 $1,426 
Restricted cash362 370 
Debt service reserves and other deposits199 194 
Cash, Cash Equivalents, and Restricted Cash$2,555 $1,990 
ASC 450—Liabilities—Supplier Finance Programs — With some purchases, AES enters into supplier financing arrangements. The Company generally uses an intermediary entity between the supplier and the Company, but sometimes enters into these agreements directly with the supplier, with the goal of securing improved payment terms. These arrangements are included in Supplier financing arrangements on the Condensed Consolidated Balance Sheets as the amounts are all due in less than a year; the related interest expense is recorded on the Condensed Consolidated Statements of Operations within Interest expense. The company had 32 supplier financing arrangements with a total outstanding balance of $875 million as of March 31, 2024, and 46 supplier financing arrangements with a total outstanding balance of $974 million as of December 31, 2023. The agreements ranged from less than $1 million to $96 million with a weighted average interest rate of 7.60% as of March 31, 2024; as of December 31, 2023, the agreements ranged from less than $1 million to $69 million with a weighted average interest rate of 7.51%. Of the amounts outstanding under supplier financing arrangements, $725 million and $814 million were guaranteed by the Company as of March 31, 2024 and December 31, 2023, respectively.
New Accounting Pronouncements Adopted in 2024 — The following table provides a brief description of recent accounting pronouncements that had an impact on the Company’s condensed consolidated financial statements.

New Accounting Standards Adopted
ASU Number and NameDescriptionDate of AdoptionEffect on the financial statements upon adoption
2022-04,Liabilities - Supplier Finance Programs (Topic 450-50): Disclosure of Supplier Finance Program ObligationsThis update is to provide additional information and disclosures about an entity’s use of supplier finance programs to see how these programs will affect an entity’s working capital, liquidity, and cash flows. Entities that use supplier finance programs as the buyer party should disclose (1) the key terms of the payment terms and assets pledged as security or other forms of guarantees provided and (2) the unpaid amount outstanding, a description of where those obligations are presented on the balance sheet, and a rollforward of those obligations during the annual period.January 1, 2023, except for the rollforward information, which is effective for fiscal years beginning after December 15, 2023.The ASU only requires disclosures related to the Company's supplier finance programs and does not affect the recognition, measurement, or presentation of supplier finance program obligations on the balance sheet or cash flow statement. The Company adopted the new disclosure requirements in the first quarter of 2023, except for the annual requirement to disclose rollforward information, which the Company expects to adopt and present prospectively beginning in the 2024 annual financial statements.
New Accounting Pronouncements Issued But Not Yet Effective — The following table provides a brief description of recent accounting pronouncements that could have a material impact on the Company’s condensed consolidated financial statements once adopted. Accounting pronouncements not listed below were assessed and determined to be either not applicable or are expected to have no material impact on the Company’s condensed consolidated financial statements.
New Accounting Standards Issued But Not Yet Effective
ASU Number and NameDescriptionDate of AdoptionEffect on the financial statements upon adoption
2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
The amendments in this section are designed to improve the disclosures related to segment reporting on an interim and annual basis. Public companies must disclose significant segment expenses and an amount for other segment items. This will also require that a company disclose its annual disclosures under Topic 280 in each interim period. Furthermore, companies will need to disclose the Chief Operating Decision Maker (“CODM”) and how the CODM assesses the performance of a segment. Lastly, public companies that have a single reportable segment must report the required disclosures under Topic 280.
The amendments in this Update are effective for fiscal years beginning after
December 15, 2023, and interim periods within fiscal years beginning after
December 15, 2024. Early adoption is permitted.
This ASU only affects disclosures, which will be provided when the amendment becomes effective.
2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures
The amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. Furthermore, companies are required to disclose a disaggregated amount of income taxes paid at a federal, state, and foreign level as well as a breakdown of income taxes paid in an jurisdiction that comprises 5% of a company's total income taxes paid. Lastly, this ASU requires that companies disclose income (loss) from continuing operations before income tax at a domestic and foreign level and that companies disclose income tax expense from continuing operations on a federal, state, and foreign level.
The amendments in this Update are effective for fiscal years beginning after December 15, 2024
This ASU only affects disclosures, which will be provided when the amendment becomes effective.

3. FAIR VALUE
The fair value of current financial assets and liabilities, debt service reserves, and other deposits approximate their reported carrying amounts. The estimated fair values of the Company’s assets and liabilities have been determined using available market information. Because these amounts are estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. For further information on our valuation techniques and policies, see Note 5—Fair Value in Item 8.—Financial Statements and Supplementary Data of our 2023 Form 10-K.
Recurring Measurements
The following table presents, by level within the fair value hierarchy, the Company’s financial assets and liabilities that were measured at fair value on a recurring basis as of the dates indicated (in millions). For the Company’s investments in marketable debt securities, the security classes presented were determined based on the nature and risk of the security and are consistent with how the Company manages, monitors, and measures its marketable securities:

As of March 31, 2024, all available-for-sale debt securities had stated maturities within one year. There were no other-than-temporary impairments of marketable securities during the three months ended March 31, 2024. The level 3 contingent consideration relates mainly to the acquisition of Bellefield in June 2023. Credit-related impairments are recognized in earnings under ASC 326. Gains and losses on the sale of investments are determined using the specific-identification method. The following table presents gross proceeds from the sale of available-for-sale securities during the periods indicated (in millions):
