Award Timing Disclosures [Line Items] |
Award Timing MNPI Disclosure | Ameren’s Board and the Committee establish meeting schedules annually, well in advance of each meeting, to ensure a thorough and thoughtful decision process. Incentive compensation awards are typically made at regularly scheduled meetings. The following is a discussion of the timing of certain compensation decisions: • the NEOs’ base salaries for 2024 were reviewed and a 2024 base salary increase for each of the NEOs was approved at the December 2023 Committee meeting, as discussed under “— Base Salary” above; ​ • 2024 STIP target opportunities (as a percentage of base salary) were established for the NEOs at the December 2023 Committee meeting; ​ • 2024 STIP performance goals were set at the February 2024 Committee meeting; ​ • 2024 PSU and RSU grants to the NEOs under the 2024 LTIP were approved at the February 2024 Committee meeting; and ​ • The final determinations of the 2024 STIP and 2022 PSU payouts were made at the February 2025 Committee meeting. ​ Decisions relating to material elements of compensation are fully deliberated by the Committee, including, when appropriate, over the course of several Committee meetings. This allows for any follow-up to questions from Committee members in advance of a final decision. We do not time the grant of awards with the release of material non-public information. We neither backdate equity awards nor do we spring-load equity awards (i.e., make equity awards shortly before announcing market-moving information with better-than-expected results or the disclosure of a significant transaction).
