(a)For the three and six months ended June 30, 2023 the non-service cost components of net periodic benefit income were adjusted by amounts deferred of $17 million and $34 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 $5 million and $11 million, respectively, for the three and six months ended June 30, 2022. See Note 11 – Retirement Benefits for additional information.
