(a)For the three and six months ended June 30, 2020, the non-service cost components of net periodic benefit income were partially offset by amounts deferred of $(3) million and $3 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 $8 million and $15 million for three and six months ended June 30, 2019, respectively.

(b)Includes $8 million pursuant to Ameren Missouri’s March 2020 electric rate order. See Note 2 – Rate and Regulatory Matters for additional information.
