(a)For certain series of Pollution Control Bonds, interest rates are subject to periodic adjustment. Certain series may be purchased on demand at periodic interest adjustment dates. Letters of credit from banks and insurance policies support certain series. Consequently, these bonds have been classified for maturity purposes as Long-term Debt Due Within One Year - Nonaffiliated on the balance sheets. (b)Certain Pollution Control Bonds are subject to redemption earlier than the maturity date. (c)Notes payable represent outstanding promissory notes issued under term loan agreements and credit agreements with a number of banks and other financial institutions. At expiration, all notes then issued and outstanding are due and payable. Interest rates are both fixed and variable. Variable rates generally relate to specified short-term interest rates. (d)Dates represent the scheduled final payment dates for the securitization bonds. The legal maturity date is one to two years later. These bonds have been classified for maturity and repayment purposes based on the scheduled final payment date. (e)Spent Nuclear Fuel Obligation consists of a liability along with accrued interest for disposal of SNF. See “Spent Nuclear Fuel Disposal” section of Note 6 for additional information. As of December 31, 2024, outstanding long-term debt was payable as follows:

Long-term Debt Subsequent Events In January and February 2025, I&M retired $9 million and $4 million, respectively, of Notes Payable related to DCC Fuel. In January 2025, Transource Energy issued $2 million of variable rate Other Long-term Debt due in 2025. In January 2025, KPCo entered into a $150 million term loan due in February 2026. In February 2025, APCo retired $14 million of Securitization Bonds. In February 2025, AEP Texas retired $12 million of Securitization Bonds. Financing Plan (Applies to AEP and AEP Texas) As of December 31, 2024, the balance sheet of AEP Texas reflects negative working capital primarily driven by Long-term Debt Due within One Year - Nonaffiliated, Advances from Affiliates and Accounts Payable. In the near term, AEP Texas plans to issue long- term debt to provide additional liquidity and also intends to refinance the Long-term Debt due in 2025 on a long-term basis. While AEP Texas has historically been able to access the capital markets and refinance debt as it comes due, there is no guarantee this will occur. Accordingly, Parent, having available liquidity, has committed to provide sufficient liquidity to AEP Texas, as necessary, to continue operations and meet obligations as they become due until AEP Texas is able to execute its upcoming financing plan. Therefore, management does not believe there is a substantial doubt about AEP Texas’ ability to continue as a going-concern and the AEP Texas financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and the satisfaction of obligations in the normal course of business. Debt Covenants (Applies to AEP and AEPTCo) Covenants in AEPTCo’s note purchase agreements and indenture limit the amount of contractually-defined priority debt (which includes a further sub-limit of $50 million of secured debt) to 10% of consolidated tangible net assets. AEPTCo’s contractually-defined priority debt was 0.6% of consolidated tangible net assets as of December 31, 2024. The method for calculating the consolidated tangible net assets is contractually-defined in the note purchase agreements. Dividend Restrictions Subsidiary Restrictions Parent depends on its subsidiaries to pay dividends to shareholders. AEP’s subsidiaries pay dividends to Parent provided funds are legally available. Various financing arrangements and regulatory requirements may impose certain restrictions on the ability of the subsidiaries to transfer funds to Parent in the form of dividends. All of the dividends declared by AEP’s utility subsidiaries that provide transmission or local distribution services are subject to a Federal Power Act requirement that prohibits the payment of dividends out of capital accounts in certain circumstances; payment of dividends is generally allowed out of retained earnings. The Federal Power Act also creates a reserve on earnings attributable to hydroelectric generation plants. Because of their ownership of such plants, this reserve applies to APCo and I&M. Certain AEP subsidiaries have credit agreements that contain covenants that limit their debt-to-capitalization ratio to 67.5%. The method for calculating outstanding debt and capitalization is contractually-defined in the credit agreements. The most restrictive dividend limitation for certain AEP subsidiaries is through the Federal Power Act restriction, while for other AEP subsidiaries the most restrictive dividend limitation is through the credit agreements. As of December 31, 2024, the maximum amount of restricted net assets of AEP’s subsidiaries that may not be distributed to the Parent in the form of a loan, advance or dividend was $17.4 billion. The Federal Power Act restriction limits the ability of the AEP subsidiaries owning hydroelectric generation to pay dividends out of retained earnings. Additionally, the credit agreement covenant restrictions can limit the ability of the AEP subsidiaries to pay dividends out of retained earnings. As of December 31, 2024, the amount of any such restrictions were as follows:
|  | AEP |  | AEP Texas |  | AEPTCo |  | APCo |  | I&M |  | OPCo |  | PSO |  | SWEPCo
|  | (in millions)
Restricted Retained Earnings |  | $ | 3,247.9 |  | (a) | $ | 1,109.2 |  |  | $ | — |  |  | $ | 539.2 |  |  | $ | 707.0 |  |  | $ | — |  |  | $ | 267.7 |  |  | $ | 366.5 |
(a) Includes the restrictions of consolidated and non-consolidated subsidiaries. Parent Restrictions (Applies to AEP) The holders of AEP’s common stock are entitled to receive the dividends declared by the Board of Directors provided funds are legally available for such dividends. Parent’s income primarily derives from common stock equity in the earnings of its utility subsidiaries. Pursuant to the leverage restrictions in credit agreements, AEP must maintain a percentage of debt-to-total capitalization at a level that does not exceed 67.5%. The method for calculating outstanding debt and capitalization is contractually-defined in the credit agreements. AEP may not declare or pay any cash dividend or distribution on its common stock during any period when AEP defers interest on its junior subordinated notes. As of December 31, 2024, AEP had $8.6 billion of available retained earnings to pay dividends to common shareholders. AEP paid $1.9 billion, $1.8 billion and $1.6 billion of dividends to common shareholders for the years ended December 31, 2024, 2023 and 2022, respectively. Lines of Credit and Short-term Debt (Applies to AEP and SWEPCo) AEP uses its commercial paper program to meet the short-term borrowing needs of its subsidiaries. The program funds a Utility Money Pool, which funds AEP’s utility subsidiaries; a Nonutility Money Pool, which funds certain AEP nonutility subsidiaries; and the short-term debt requirements of subsidiaries that are not participating in either money pool for regulatory or operational reasons, as direct borrowers. As of December 31, 2024, AEP had $6 billion in revolving credit facilities to support its commercial paper program. Securitized Debt for Receivables, for the year ended 2024, had a weighted-average interest rate of 5.39% and a maximum amount outstanding of $900 million. The commercial paper program, for the year ended 2024, had a weighted-average yield of 5.39% and a maximum amount outstanding of $2.9 billion. AEP’s outstanding short-term debt was as follows:

(a) Weighted-average rate of all borrowings outstanding as of December 31, 2024 and 2023, respectively. (b) Amount of securitized debt for receivables as accounted for under the “Transfers and Servicing” accounting guidance. Corporate Borrowing Program (Applies to Registrant Subsidiaries) AEP subsidiaries use a corporate borrowing program to meet their short-term borrowing needs. The corporate borrowing program includes a Utility Money Pool, which funds AEP’s utility subsidiaries; a Nonutility Money Pool, which funds certain AEP nonutility subsidiaries; and direct borrowing from AEP. The AEP Utility Money Pool operates in accordance with the terms and conditions of its agreement filed with the FERC. The amounts of outstanding loans to (borrowings from) the Utility Money Pool as of December 31, 2024 and 2023 are included in Advances to Affiliates and Advances from Affiliates, respectively, on the Registrant Subsidiaries’ balance sheets. The Utility Money Pool participants’ money pool activity and corresponding authorized borrowing limits are described in the following tables: Year Ended December 31, 2024:
