(a)For the three months ended March 31, 2022 and 2021, the non-service cost components of net periodic benefit income were adjusted by amounts deferred of $6 million and less than $(1) 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.
