Performance Based Restricted Stock Units

The Company awards performance-based restricted stock units to executives and other officers and employees. Under the terms of the awards, the number of units that will vest and convert to shares of common stock will be based on the Company's performance relative to a predefined peer group over a fixed three-year performance period. The number of shares issued upon vesting will range from 0% to 200% of the PSUs granted. The Company's performance relative to the peer group will be measured based on adjusted return on average tangible common equity (non-GAAP), adjusted for unusual gains/losses, merger expenses, and other items as approved by the compensation committee of the Company's board of directors. Compensation expense for PSUs is estimated each period based on the fair value of the Company's stock at the grant date and the most probable outcome of the performance condition, adjusted for the passage of time within the performance period of the awards

The following table summarizes information about the changes in PSUs as of and for the three months ended March 31, 2023.






	Performance Stock Units Outstanding	Weighted Average Grant Date Fair Value
Balance at beginning of period (unvested)	161,667	$	41.73

Performance adjustment (1)	44,319	37.17
Vested	(90,583)	36.21
Forfeited or expired	(1,153)	44.25
Balance at end of period (unvested)	200,260	$	40.98
(1) PSUs are presented as outstanding, granted and forfeited in the table above assuming targets are met and the awards pay out at 100%. PSU awards are settled with payouts ranging from 0% and 200% of the target award value based on the Company's performance relative to a predefined peer group over a fixed three-year performance period. The performance adjustment represents the difference in shares ultimately awarded due to performance attainment above or below target.
