For further details, see Note 3. 2 Subsequent to December 31, 2024 and 2023, SCE issued first and refunding mortgage bonds which were used to partially pay down its commercial paper balance. As a result, SCE included the paydown amount of $706 million and $722 million in other long-term debt at December 31, 2024 and 2023, respectively. The 2023 amount also includes a $600 million term loan with an interest rate of adjusted term secured overnight financing rate ("SOFR") plus 0.90% that matured in 2024. Edison International and SCE long-term debt maturities over the next five years are as follows:

The proceeds were used to repay commercial paper borrowings and for general corporate purposes. Liens and Security Interests Almost all of SCE's properties are subject to a trust indenture lien. SCE has pledged first and refunding mortgage bonds as collateral for borrowed funds obtained from pollution-control bonds issued by government agencies. SCE has a debt covenant that requires a debt to total capitalization ratio to be less than or equal to 0.65 to 1. At December 31, 2024, SCE's debt to total capitalization ratio was 0.58 to 1 and was in compliance with all other financial covenants that affect access to capital. Edison International Parent's credit facility requires a consolidated debt to total capitalization ratio as defined in the applicable agreements of less than or equal to 0.70 to 1. At December 31, 2024, Edison International consolidated debt to total capitalization ratio was 0.65 to 1. Credit Agreements and Short-Term Debt The following table summarizes the status of the credit facilities at December 31, 2024:

This includes $706 million and $722 million, at December 31, 2024 and 2023, respectively, outstanding commercial paper reclassified from "Short-term debt" to "Long-term debt" on the consolidated balance sheets, due to subsequent debt refinancing. 3 The aggregate maximum principal amount under the Edison International Parent and SCE revolving credit facilities may be increased up to $2.0 billion and $4.0 billion, respectively, provided that additional lender commitments are obtained. In May 2024, Edison International Parent and SCE amended their credit facilities to extend the maturity date to May 2028, with additional one-year extension options. Uncommitted Letters of Credit SCE has agreements with certain lenders for bilateral unsecured standby letters of credit ("SBLC") with a total capacity of $625 million that is uncommitted and supported by reimbursement agreements. The SBLCs are not subject to any collateral or security requirements. At December 31, 2024, SCE had $118 million in standby letters of credit outstanding under these agreements, which expire between January and December 2025. The unused capacity under these agreements was $507 million.
