(3) Equity-based compensation. Compensation is performance-based compensation if it is based solely on an increase in the value of the service recipient, or a share of stock in the service recipient, after the date of a grant or award. However, compensation payable for a service period that is equal to the value of a predetermined number of shares of stock, and is variable only to the extent that the value of such shares appreciates or depreciates, generally will not be performance-based compensation. Notwithstanding the foregoing, the attainment of a prescribed value for the service recipient (or a portion thereof), or a share of stock in the service recipient, may be used as a preestablished organizational criterion for purposes of providing performance-based compensation, provided that the other requirements of paragraph (e)(1) of this section are satisfied. In addition, an award of equity-based compensation may constitute performance-based compensation if entitlement to the compensation is subject to a condition that would cause the award to otherwise qualify as performance-based compensation, such as a performance-based vesting condition. A provision that allows a service provider to defer compensation that would be realized upon the exercise of a stock right generally constitutes an additional deferral feature for purposes of the definition of a deferral of compensation under paragraph (b)(5) of this section.
