Note B — Stock Options and Stock-Based Compensation

Under the Company’s Restated Omnibus Incentive Plan (Formerly The Restated 1988 Executive Stock Option Plan) (“the Plan”) as in effect at March 31, 2015, options for up to 19,365,000 shares of the Company’s common stock may be granted over the life of the Plan to key employees, non-employee directors and consultants at exercise prices not less than the fair market value of the stock at the date of grant. Options granted under the Plan are non-statutory stock options and generally vest 25% one year from date of grant and the remaining 75% vesting ratably each month for the next 36 months. The options granted to employees and the board of directors expire at the end of five years and ten years from date of grant, respectively.

The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option-pricing model with the assumptions included in the table below. The Company uses historical data among other factors to estimate the expected volatility, the expected option life, and the expected forfeiture rate. The risk-free rate is based on the interest rate paid on a U.S. Treasury issue with a term similar to the estimated life of the option. During fiscal 2015, based upon the historical experience of option cancellations, the Company has an estimated annualized forfeiture rate of 11.8%. Forfeiture rates will be adjusted over the requisite service period when actual forfeitures differ, or are expected to differ, from the estimate.

The fair value of each grant is estimated on the date of grant using the Black-Scholes option-pricing model. The following weighted average assumptions were used for fiscal years ended March 31, 2013, 2014 and 2015:

Fiscal 2013

Included in the above-noted stock option grants and stock compensation expense are performance-based stock options pursuant to which vesting occurs only upon the Company achieving certain earnings per share targets as determined by the Company’s board of directors. The options were valued in the same manner as the time-vesting options. However, the Company only recognizes stock compensation to the extent that the targets are probable which allow the performance options to vest. During fiscal years ended March 31, 2013, 2014, and 2015, the Company recognized stock compensation expense for performance-based options in the amount of ($82,000), $630,000, and $211,000, respectively.

The Company received $3,399,000, $3,386,000, and $1,603,000 of cash receipts from the exercise of stock options during fiscal 2013, 2014, and 2015, respectively. As of March 31, 2015, $4,820,000 of total unrecognized compensation costs related to stock options is expected to be recognized over a weighted average period of 3 years.
