[1] | The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted price of Pinnacle Financial common stock of $73.40 per common share at December 31, 2022 for the 40,188 options that were in-the-money at December 31, 2022.
[2] | The forfeiture restrictions on these restricted share awards lapse in equal annual installments on the anniversary date of the grant.
[3] | These shares represent forfeitures resulting from recipients whose employment or board membership was terminated during the year-to-date period ended December 31, 2022. Any dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by Pinnacle Financial at the time of termination or will not be distributed from escrow, as applicable
[4] | Restricted share awards are issued to the outside members of the board of directors in accordance with their board compensation plan. Restrictions lapse on March 1, 2023 based on each individual board member meeting attendance goals for the various board and board committee meetings to which each member was scheduled to attend.
[5] | These shares represent forfeitures resulting from recipients whose employment was terminated during the life-to-date period ended December 31, 2022. Dividend equivalents are held in escrow for award recipients for dividends paid prior to the forfeiture restrictions lapsing. Such dividend equivalents are not released from escrow if an award is forfeited.
[6] | The named executive officers are awarded a range of awards that generally may be earned based on attainment of goals between a target level of performance and a maximum level of performance. The 230,000 performance units awarded to the NEOs in 2022 may be earned based on target level performance and do not include maximum level payout.
