Performance Based Awards Program

The Company’s Compensation Committee approved a short-term performance-based bonus program for fiscal year 2016 with predetermined objectives related to revenue and expense targets. In the event the fiscal year 2016 objectives were met, eighty-percent of the options would have vested on June 30, 2016. On August 21, 2015, certain executives and senior managers were granted an aggregate of 75,500 stock options in connection with this program. The stock options have an exercise price of $5.80 and expire ten years from the date of grant. At March 31, 2016, it was determined targets were met related to 50,400 stock options which vested on June 30, 2016. At March 31, 2016, 10,000 stock options expired due to targets that were not met. The vesting of the remaining 15,100 stock options was at the discretion of the Company’s Compensation Committee. The Company’s Compensation Committee determined 14,772 of the 15,100 discretionary stock options vested at June 30, 2016 and 228 of the discretionary stock options expired unvested.

The Company also approved a long-term market-based stock option bonus program for senior managers. Vesting of the stock options granted as part of this program is contingent upon the achievement of four separate target stock prices. The market-based options vest based on the 30-trading day trailing average of the stock price of the Company’s common stock with options vesting in 25% increments at each of the target stock prices. On the last day of each quarter, the chief executive officer and/or chief financial officer will determine if any of the target stock prices have been met by evaluating the period between the quarter end date and the grant date of the option. In the event that a target stock price has been met, the senior manager will be notified that such options have vested. At the end of five years from the date of the grant, if the stock target prices have not been met, then the unvested portion of the option will expire. On August 21, 2015, certain senior managers were granted an aggregate of 23,750 stock options in connection with this program. The stock options have an exercise price of $5.80 and if they vest will expire ten years from the date of grant. None of these options vested as of March 31, 2018.

Stock-Based Compensation

On April 1, 2017, the Company adopted ASU 2016-09 and, as a result, made a Company-wide accounting policy change with respect to accounting for forfeitures. The Company applied a modified retrospective approach for adoption of the new policy and accordingly recorded an $11,000 increase to opening accumulated deficit at April 1, 2017. In accordance with the adoption of the accounting policy, the Company no longer estimates forfeitures based on historical experience and no longer reduces compensation expense based on the expected forfeitures. Beginning April 1, 2017, the Company will record forfeitures as they occur and will reduce compensation cost at the time of forfeiture.

The Company issues service, performance and market-based stock options to employees and non-employees. The Company estimates the fair value of service and performance stock option awards using the Black-Scholes option pricing model. The Company estimates the fair value of market-based stock option awards using a Monte-Carlo simulation. Compensation expense for stock option awards is amortized on a straight-line basis over the awards’ vesting period. Compensation expense includes the impact of an estimate for forfeitures for all stock options.

The expected term of the stock options represents the average period the stock options are expected to remain outstanding and is based on the expected term calculated using the approach prescribed by the Securities and Exchange Commission's Staff Accounting Bulletin No. 110 for “plain vanilla” options. The expected stock price volatility for the Company’s stock options was determined by using an average of the historical volatilities of the Company and its industry peers. The Company will continue to analyze the stock price volatility and expected term assumptions as more data for the Company’s common stock and exercise patterns become available. The risk-free interest rate assumption is based on the U.S. Treasury instruments whose term was consistent with the expected term of the Company’s stock options. The expected dividend assumption is based on the Company’s history and expectation of dividend payouts.

The Company estimated the fair value of employee and non-employee stock options using the Black-Scholes option pricing model. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service periods of the respective awards. The fair value of employee stock options was estimated using the following weighted-average assumptions:

Share-based awards compensation expense is as follows:

At March 31, 2018, there were unrecognized compensation costs of $2,253,000 related to stock options which is expected to be recognized over a weighted-average amortization period of 1.99 years.
