[1] | Includes 750 stock options which were exercised in a stock swap transaction which settled in 277 shares of Pinnacle Financial common stock.
[2] | 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 $64.00 per common share at December 31, 2019 for the 119,274 options that were in-the-money at December 31, 2019.
[3] | Groups include employees (referred to as associates above), the leadership team which includes our named executive officers and other key senior leadership members, and outside directors. When the restricted shares are awarded, a participant receives voting rights and forfeitable dividend rights with respect to the shares, but is not able to transfer the shares until the restrictions have lapsed. Once the restrictions lapse, the participant is taxed on the value of the award and may elect to sell some shares (or have Pinnacle Financial withhold some shares) to pay the applicable income taxes associated with the vested portion of the award. For time-based vesting restricted share awards, dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by Pinnacle Financial at the time of termination. For performance-based vesting awards and time-based vesting awards to Pinnacle Financial's executive officers, dividends are placed into escrow until the forfeiture restrictions on such shares lapse.
[4] | The forfeiture restrictions on these restricted share awards lapse in equal annual installments on the anniversary date of the grant.
[5] | These shares represent forfeitures resulting from recipients whose employment or board membership is terminated during each of the years in the three-year period ended December 31, 2019 or for which the performance criteria applicable to the award are not achieved. 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.
[6] | Restricted share awards issued to associates that were former associates of BNC and to Pinnacle Financial's Chairman of the Carolinas and Virginia pursuant to legacy BNC incentive plans assumed by Pinnacle Financial.
[7] | Reflects conversion of restricted share units issued in prior years to restricted share awards. The forfeiture restrictions on these restricted share awards lapse should Pinnacle Financial achieve certain soundness targets at the end of the fifth year following the grant date. See further details of these awards under the caption "Restricted Share Units" below.
[8] | Restricted share awards are issued to the outside members of the board of directors in accordance with their board compensation plan. Restrictions on those awards granted in 2019 lapse on February 29, 2020 based on each individual board member meeting their attendance goals for the various board and board committee meetings to which each member was scheduled to attend.
[9] | The named executive officers are awarded a range of awards that may be earned based on attainment of goals at a target level of performance to the maximum level of performance.
