12. Stock-Based Compensation

For the years ended April 30, 2020, 2019 and 2018, the Company recorded stock-based compensation expense of approximately $6,227,000, $6,985,000 and $4,956,000, respectively.

On January 14, 2007, the stockholders of the Company approved the 2006 Equity Incentive Plan (“2006 Plan”) effective January 21, 2007, for officers, directors, key employees and consultants. On September 29, 2011, the stockholders of the Company approved an amendment and restatement of the 2006 Plan (“Restated 2006 Plan”). Under the Restated 2006 Plan, incentive stock options, nonqualified stock options, restricted stock awards, stock appreciation right awards, performance share awards, performance stock unit awards, dividend equivalents awards, stock payment awards, deferred stock awards, restricted stock unit awards, other stock-based awards, performance bonus awards or performance-based awards may be granted at the discretion of the compensation committee, which consists of outside directors. A maximum of 4,884,157 shares of stock may be issued pursuant to awards under the Restated 2006 Plan. The maximum number of shares of common stock with respect to one or more awards that may be granted to any one participant during any twelve month period is 2,000,000. A maximum of $5,000,000 may be paid in cash to any one participant as a performance-based award during any twelve month period. The exercise price for any incentive stock option shall not be less than 100% of the fair market value on the date of grant. Vesting of awards is established at the time of grant.

The Company had an equity incentive plan (“2002 Plan”) for officers, directors and key employees. Under the 2002 Plan, incentive stock options or nonqualified stock options were granted, as determined by the administrator at the time of grant. Stock purchase rights were also granted under the 2002 Plan. Options under the 2002 Plan were granted at their fair market value (as determined by the board of directors). The options became exercisable at various times over a five-year period from the grant date. The 2002 Plan was terminated on the effective date of the 2006 Plan. Awards outstanding under the 2002 Plan remain outstanding and exercisable; no additional awards may be made under the 2002 Plan.

The Company had a 1992 nonqualified stock option plan (“1992 Plan”) for certain officers and key employees. Options under the 1992 Plan were granted at their fair market value (as determined by the board of directors) at the date of grant and became exercisable at various times over a five-year period from the grant date. The 1992 Plan expired in August 2002.

No options were granted during the fiscal years ended April 30, 2020, 2019 and 2018. The fair value of stock options granted previously was estimated at the grant date using the Black-Scholes option pricing model. Assumptions included in the Black-Scholes option pricing model included the expected term of stock options, the expected volatility, the risk free interest rate, and the expected dividend yield. The expected term of stock options represents the weighted average period the Company expects the stock options to remain outstanding, based on the Company’s historical exercise and post-vesting cancellation experience and the remaining contractual life of its outstanding options. The expected volatility is based on historical volatility for the Company’s stock. The risk free interest rate is based on the

implied yield on a U.S. Treasury zero-coupon bond with a remaining term that approximates the expected term of the option. The expected dividend yield of zero reflects that the Company has not paid any cash dividends since inception and does not anticipate paying cash dividends in the foreseeable future.
