Edison International and SCE provide and receive various services to and from its subsidiaries and affiliates. Services provided to Edison International by SCE are priced at fully loaded cost (i.e., direct cost of goods or service and allocation of overhead cost). Specified administrative services performed by Edison International or SCE employees, such as payroll and employee benefit programs, are shared among all affiliates of Edison International. Costs are allocated based on one of the following formulas: percentage of time worked, equity in investment and advances, number of employees, or multi-factor (operating revenue, operating expenses, total assets and number of employees). Edison International allocates various corporate administrative and general costs to SCE and other subsidiaries using established allocation factors.

For the years ended December 31, 2024 and 2023, SCE did not purchase wildfire liability insurance from EIS. Beginning on July 1, 2023, in lieu of obtaining wildfire liability insurance from the commercial insurance market, SCE implemented its customer-funded wildfire self-insurance program. For the year ended December 31, 2022, SCE purchased wildfire liability insurance for premiums of $273 million from EIS. EIS fully reinsured the exposure for these policies through the commercial reinsurance market, with reinsurance limits and premiums equal to those of the insurance purchased by SCE, except for a contract for a premium of $93 million for the 12 months ended June 30, 2023 under which EIS provided insurance protection to SCE. SCE recorded the premium as insurance expense and recorded an equal amount of revenue due to customer funding through regulatory cost recovery mechanisms, therefore there was no earnings impact on SCE's consolidated statements of income. EIS recorded the premium as insurance revenue. On the Edison International consolidated statements of income, the EIS insurance revenue was eliminated with SCE's insurance expense, therefore the SCE customer revenues increased the earnings of Edison International. The amount of insurance expense and corresponding revenue was $44 million for the year ended December 31, 2023. The expected insurance recoveries from previously purchased wildfire-related insurance from EIS included in SCE's consolidated balance sheets were $303 million and $355 million at December 31, 2024 and December 31, 2023, respectively. The expense for wildfire-related insurance premiums paid to EIS was $132 million and $213 million for the years ended December 31, 2023 and 2022, respectively.

There were no contributions in 2023 and 2022.
