Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.


(e) On June 10, 2010, the Human Resources Committee (the “Committee”) of the Board of Directors (the “Board”) of Ameren Corporation (“Ameren”) approved and on June 11, 2010, the Board ratified an increase to the base salary of Mr. Thomas R. Voss, Ameren’s Chairman, President and Chief Executive Officer, from $750,000 to $817,500, effective as of July 1, 2010, and Mr. Martin J. Lyons, Jr., Ameren’s Senior Vice President and Chief Financial Officer, from $390,000 to $460,000, effective as of June 16, 2010. The Committee’s decision to adjust Messrs. Voss’s and Lyons’s base salary was based on a number of factors, including but not limited to their individual performance and the Committee’s review of base salary market data for the chief executive officer and chief financial officer positions at similar regulated utility industry companies, which review indicated that each of Messrs. Voss’s and Lyons’s current base salary is below eighty percent of the market median. All other material terms and conditions of Messrs. Voss’s and Lyons’s compensatory plans, contracts or arrangements with Ameren remain the same.




Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
