(1) The income tax benefits associated with the pension and OPEB prior service costs amortized out of AOCI were $2 million and $3 million for the nine months ended September 30, 2022 and 2021, respectively.

On March 11, 2021, President Biden signed into law the American Rescue Plan Act of 2021, which among other things, extended shortfall amortization periods and modification of the interest rate stabilization rules for single-employer plans thereby impacting funding requirements. As a result, FirstEnergy does not currently expect to have a required contribution to the pension plan based on various assumptions, including an expected future annual return on assets of 7.50%. However, FirstEnergy may elect to contribute to the pension plan voluntarily.
Service costs, net of capitalization, are reported within Other operating expenses on FirstEnergy’s Consolidated Statements of Income. Non-service costs, other than the pension and OPEB mark-to-market adjustment, which is separately shown, are reported within “Miscellaneous income, net”, within “Other Income (Expense)” on FirstEnergy’s Consolidated Statements of Income.
