contributions are being reflected in "Wildfire Insurance Fund Expense" in the consolidated statements of income. Changes in the estimated period of coverage provided by the Wildfire Insurance Fund could lead to material changes in future expense recognition. In estimating the period of coverage, Edison International and SCE used Monte Carlo simulations based on historical data from wildfires caused by electrical utility equipment to estimate expected losses, using ten years (2014 – 2023) of available historical data in 2024, nine years (2014 – 2022) of available historical data in 2023, and eight years (2014 – 2021) of available historical data in 2022. The details of the operation of the Wildfire Insurance Fund and estimates related to claims by SCE, PG&E, and SDG&E against the fund have been applied to the expected loss simulations to estimate the period of coverage of the fund. The most sensitive inputs to the estimated period of coverage are the expected frequency of wildfire events caused by investor-owned utility electrical equipment and the estimated costs associated with those forecasted events. These inputs are most affected by the historical data used in estimating expected losses. There were fires in the service area of SCE, PG&E and SDG&E since the inception of the Wildfire Insurance Fund, including fires for which the cause is unknown, which may in the future be determined to be covered by the Wildfire Insurance Fund and have not been reflected or estimated in this analysis will be included in this analysis at that time. As of the date of this filing, SCE is continuing to perform its annual assessment for 2025 to reassess its estimate of the life of the Wildfire Insurance Fund
