Stock Incentive Plans - Grants and Fair Value

Stock Options

No options were granted during the first quarter of fiscal 2014 or 2013. The Black-Scholes option pricing model is used to estimate the fair value of options.

Restricted Stock

The fair value of the restricted stock units granted is the intrinsic value as of the respective grant date since the restricted stock units are granted at no cost to the employee. The weighted-average grant date fair values of restricted stock units granted during the first quarter of fiscal 2014 and 2013 were $1.32 and $2.20, respectively.

Stock Purchase Plan

Under the Purchase Plan, rights to purchase shares are typically granted during the second and fourth quarter of each fiscal year. No rights to purchase shares were granted during the first quarter of fiscal 2014 or 2013. The Black-Scholes option pricing model is used to estimate the fair value of rights to acquire stock granted under our Purchase Plan.
