Share-based Compensation [Abstract]

Stock-Based Compensation

Stock-Based Compensation

The Company currently has one equity-based compensation plan from which stock-based compensation awards can be granted to employees and directors. In addition, the Company has plans that have been terminated as to future grants, but under which options are currently outstanding. The Company also has an Employee Stock Purchase Plan ("ESPP") that provides employees with the opportunity to purchase the Company’s common stock at a discount. The ESPP was amended in the second quarter of fiscal 2012 to increase the six-month participation period to a twelve-month participation period, divided into two equal six-month purchase periods and provide for a look-back feature. At the end of each six-month period, employees purchase the Company's common stock through the ESPP at 15% less than the fair market value of the common stock on the first day of the twelve-month participation period or the purchase date, whichever is lower. The plan amendment also provides for an automatic reset feature to start participants on a new twelve-month participation period if the share value declines during the first six-month purchase period.

Stock-Based Compensation Valuation and Expense

The Company accounts for its employee stock-based compensation plan using the fair value method. The fair value method requires the Company to estimate the grant date fair value of its stock-based awards and amortize this fair value to compensation expense over the requisite service period or vesting term.

To estimate the fair value of the Company's stock option awards the Company currently uses the Black-Scholes option-pricing model. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by the Company's stock price as well as assumptions regarding a number of complex and subjective variables. These variables include the expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rate and expected dividends. Due to the inherent limitations of option-valuation models available today, including future events that are unpredictable and the estimation process utilized in determining the valuation of the stock-based awards, the ultimate value realized by award holders may vary significantly from the amounts expensed in the Company's financial statements.

For restricted stock and stock unit awards, grant date fair value is based upon the market price of the Company's common stock on the date of the grant. This fair value is then amortized to compensation expense over the requisite service period or vesting term.

Stock-based compensation expense is recorded net of estimated forfeitures such that expense is recorded only for those stock-based awards that are expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates.Total stock-based compensation expense was as follows (in thousands):
