Stock-Based Compensation [Abstract] |
Stock-Based Compensation | Note 5 — Stock-Based Compensation We have stock-based compensation plans under which employees may be granted performance-based stock awards and other restricted stock awards. Prior to fiscal year 2017, we also granted options to purchase shares of our common stock at the fair market value at the time of grant. We recognize the grant date fair value of stock-based compensation in net income on a straight-line basis, net of estimated forfeitures over the requisite service period. The measurement of performance for performance-based stock awards is based on actual financial results for targets established three years in advance. For the three months ended January 31, 2019 and 2018, we recognized stock-based compensation expense, on a pre-tax basis, of $6.1 million and $4.0 million, respectively. For the nine months ended January 31, 2019 and 2018, we recognized stock-based compensation expense, on a pre-tax basis, of $15.0 million and $6.5 million, respectively. The following table summarizes restricted stock awards we granted:
