Equity Incentive Plan and Stock-Based Compensation


Equity Incentive Plan 


The Company’s 2010 Equity Incentive Award Plan (2010 Plan) provides for the grant of stock options, stock appreciation rights, restricted stock units, restricted stock, performance awards, and deferred stock to its employees, consultants and non-employee members of its Board of Directors.


In the first quarter of fiscal 2014, the Company granted performance awards to certain senior executives where vesting is subject to achievement of performance goals established by the Compensation Committee of the Company’s Board of Directors. Performance is measured based on a combination of the Company achieving certain financial targets and a relative total shareholder return (TSR) goal. The TSR goal is based on the Company’s TSR measured against a benchmark TSR of a peer group over a three-year period. These awards vest at the end of the performance period of 3 years from the grant date. The number of stock awards to vest will range from 0% to 150% of the original awards granted. In evaluating the fair value of these awards, the Company used a combination of the stock price at the close of market on grant date, for the performance condition, and a Monte Carlo simulation on grant date, taking the market-based goal into consideration, for the market condition. 


 The numbers of shares of common stock available for grant under the 2010 Plan are shown in the following table:
