(1)	The performance awards issued on November 18, 2022, included 3,517 target shares and 1,759 excess shares for exceeding performance targets. The performance awards vesting on November 18, 2025, included 844 shares of the 1,759 total excess performance shares granted. The remaining 915 shares of excess performance awards granted were not earned and did not vest because the remaining performance criteria were not achieved and thus, those 915 shares were forfeited on November 18, 2025.
