Stock-Based Compensation |
The Company has two equity incentive plans that provide for the granting of stock options, restricted stock, stock appreciation rights, stock units, and performance cash awards to certain employees, members of the board of directors, and consultants of the Company with a generally prescribed contractual term of ten years. As of March 31, 2021, there were 3,947,976 shares of common stock available for grant under the Company’s equity incentive plans. In 2019 and 2020 the Company granted performance cash awards. The bonus units vest in four annual installments from the date of grant and entitle the employees to receive a cash payment, on the earlier of (i) four years from the date of grant or (ii) a change of control, equal in value to the amount by which the then value of the Company’s common stock exceeds the base value. As of March 31, 2021, $1.4 million was accrued as compensation expense for vested performance cash awards. The Company recognizes stock-based compensation expense over the requisite service period.
