|6. Stock-Based Compensation||
The Company accounts for share-based awards exchanged for employee services at the estimated grant date fair value of the award. The Company amortizes the fair value of employee stock options on a straight-line basis over the requisite service period of the awards. Compensation expense includes the impact of an estimate for forfeitures for all stock options. The estimated forfeiture rates used during the six months ended September 30, 2013 ranged from 1.63% to 4.77%.
Employee stock-based compensation expense is as follows (in thousands):
At September 30, 2013, there were unrecognized compensation costs of $1,403,000 related to stock options which are expected to be recognized over a weighted-average amortization period of 2.54 years.
The Company estimated the fair value of 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:
The expected term of 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 Companys stock options was determined by examining the historical volatility of the Company and the historical volatilities of the Companys industry peers. The Company will continue to analyze the stock price volatility and expected term assumptions as more data for the Companys 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 Companys stock options. The expected dividend assumption is based on the Companys history and expectation of dividend payouts. The Company estimates forfeitures based on historical experience and reduces compensation expense accordingly.
A summary of all option activity as of September 30, 2013 and changes during the six months then ended is presented below:
The aggregate intrinsic value is calculated as the difference between the exercise price of the stock options and the underlying fair value of the Companys common stock ($2.74) for stock options that were in-the-money as of September 30, 2013.
