The Company has stock-based compensation plans under which employees may be granted performance-based stock awards and other restricted stock awards. Prior to fiscal year 2017, the Company also granted options to purchase shares of Company common stock at the fair market value at the time of grant. The Company recognizes the grant date fair value of stock-based compensation in net income on a straight-line basis over the requisite service period.
