Under the Company’s Employee Stock Option Plan, as amended and restated as of April 4, 2013 (the “Plan”), the Compensation Committee of the Board of Directors, which consists of four of the Company’s non-employee directors, has the authority to grant participants incentive stock options, nonqualified stock options, restricted stock, stock appreciation rights and stock awards, for up to 11,000,000 shares of common stock.

Stock options granted to participants under the Plan generally become exercisable in equal installments over three years or cliff-vested after three years and remain exercisable until the tenth anniversary of the date of grant. All stock options granted under the Plan have an exercise price equal to or greater than the fair market value of the Company’s common stock on the grant date.

The table below presents the weighted average assumptions used with the Black-Scholes option-pricing model for the calculation of the fair value of stock options granted during the fiscal years ended January 31, 2018 and 2017. There were no stock options granted during the fiscal year ended January 31, 2019.

The fair value of the stock options, less expected forfeitures, is amortized on a straight-line basis over the vesting term. Total compensation expense for stock option grants recognized during the fiscal years ended January 31, 2019, 2018 and 2017 was $0.8 million (net of tax of $0.2 million), $0.5 million (net of tax of $0.3 million), and $1.3 million (net of tax of $0.8 million), respectively. As of January 31, 2019, there was $0.6 million of unrecognized compensation cost related to unvested stock options. These costs are expected to be recognized over a weighted-average period of 0.6 years. Total consideration received for stock option exercises during the fiscal years ended January 31, 2019, 2018 and 2017 was $5.9 million, $2.0 million and $1.0 million, respectively. The windfall tax provision realized on these exercises in fiscal 2019 was $0.2 million.

The following table summarizes the Company’s stock option plan as of January 31, 2019 and changes during each of the fiscal years in the three-year period ended January 31, 2019:

Upon the vesting of a stock award, shares are issued from the pool of authorized shares. The number of shares issued can vary from 0% to 150% of the target number of underlying stock award units, depending on the extent of the achievement of predetermined financial goals. The total fair value of stock award units that vested during fiscal 2019, 2018 and 2017 was $3.1 million, $2.6 million and $4.8 million, respectively. Unvested stock award units had a total fair value of $14.3 million, $10.5 million and $10.3 million, for fiscal 2019, 2018 and 2017, respectively. The windfall tax benefit realized on the vested stock awards for fiscal 2019 was $0.3 million.
