STOCK-BASED COMPENSATION

11. STOCK-BASED COMPENSATION

Historically, stock options have been granted with an exercise price equal to the market value of the common stock on the date of grant, with expiration 10 years from the date they are granted, and generally vest over a one to three-year period for employees and members of the Board. Upon exercise, new shares will be issued by the Company. The restricted shares and restricted stock units (“RSUs”) granted to Board members and employees generally have a three-year graded vesting period and are subject to accelerated vesting and forfeiture under certain circumstances.

The following table provides the weighted average assumptions used in determining the fair value of the stock option awards granted during the three-month period ended March 31, 2022. There were no stock option awards issued in the three months ended March 31, 2023.
