Management's first quarter 2024 review of its loss estimates for remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events resulted in a $490 million increase in estimated losses, primarily driven by information obtained during the quarter related to the Woolsey Fire mediation program.

SCE is unable to conclude that uninsured CPUC-jurisdictional wildfire-related costs are probable of recovery through electric rates. SCE would record a regulatory asset at the time it obtains sufficient information to support a conclusion that recovery is probable.

Edison International and SCE may incur a material loss in excess of amounts accrued in connection with the remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events.

SCE issued $500 million of first and refunding mortgage bonds due in 2027 and $900 million of first and refunding mortgage bonds due in 2034. In March 2024, SCE issued $600 million of first and refunding mortgage bonds due in 2026, $600 million of first and refunding mortgage bonds due in 2029 and $400 million of first and refunding mortgage bonds due in 2054.

In March 2024, Edison International repurchased 20,000 shares of its Series B Preferred Stock on the open market at an average price of $952 per share, including accrued and unpaid dividends for an aggregate amount of $19 million.

Total capital expenditures (including accruals) were $1.2 billion and $1.3 billion for the first three months ended March 31, 2024 and 2023, respectively. As discussed in 2023 Form 10-K, SCE forecasts total capital expenditures ranging from $32.2 billion to $37.5 billion for 2024 – 2028.

SCE is unable to conclude that uninsured CPUC-jurisdictional wildfire-related costs are probable of recovery through electric rates. SCE would record a regulatory asset at the time it obtains sufficient information to support a conclusion that recovery is probable.

SCE's credit ratings may be affected if, among other things, regulators fail to successfully implement AB 1054 in a consistent and credit supportive manner, or the Wildfire Insurance Fund is depleted by claims from catastrophic wildfires.

As a result of the CPUC-authorized decoupling mechanism, SCE revenues are not affected by changes in volume of retail electricity sales.
