(a)For the three and nine months ended September 30, 2025, the non-service cost components of net periodic benefit income were adjusted by amounts deferred of $(9) million and $(41) million, respectively, due to a regulatory tracking mechanism for the difference between the level of such costs incurred by Ameren Missouri under GAAP and the level of such costs included in rates. The deferral was $(11) million and $(31) million, respectively, for the three and nine months ended September 30, 2024. See Note 11 – Retirement Benefits for additional information.
(b)See Note 4 – Long-term Debt and Equity Financings for additional information on Ameren (parent)’s repurchase of Ameren Missouri’s senior secured notes and first mortgage bonds and Ameren Illinois’ first mortgage bonds that were accounted for as a debt extinguishment.
