Stock-Based Compensation [Abstract] 
STOCK-BASED COMPENSATION
(3) STOCK-BASED COMPENSATION
2004 Equity Compensation Plan
Under the terms of the Company’s 2004 Equity Compensation Plan (“2004 Plan”), the Human Resources Committee (“Committee”) of the Board of Directors (“Board”) may grant incentive stock options, non-qualified stock options, restricted stock grants, stock appreciation rights, stock bonuses and other awards to officers and other employees. Grants under the 2004 Plan may be made through August 3, 2014. The term of each grant is at the discretion of the Committee, but in no event greater than ten years from the date of grant. The Committee has discretion to determine the date or dates on which granted options become exercisable. During the first quarter of fiscal 2012, the Company granted performance-based stock options and performance-based restricted stock units (“RSUs”) which vest provided that certain performance metrics have been met during the performance period. All options outstanding as of September 30, 2011 become exercisable at the rate of 25% per year commencing one year after the date of grant; in some cases, however, exercisability is further conditioned upon satisfaction of performance-based vesting criteria. Outstanding RSUs generally vest (subject to limited exceptions) at the rate of 50% of the shares underlying the grant on each of the third and fourth anniversaries of the date on which the award was granted; in some cases, however, vesting is further conditioned upon satisfaction of performance-based vesting criteria.
On May 24, 2011, the Board approved an amendment to the 2004 Plan to reduce the number of shares of the Company’s common stock authorized for issuance under the 2004 Plan by 500,000 shares. As a result of this reduction, the 2004 Plan now provides that 1,500,000 shares of the Company’s common stock may be issued as grants under the 2004 Plan. Prior to this amendment, the 2004 Plan provided that 2,000,000 shares of the Company’s common stock could be issued as grants under the 2004 Plan. At September 30, 2011, 785,879 shares were available for grant under the 2004 Plan.
2011 Stock Option Plan for Non-Employee Directors
On August 2, 2011, the Company’s stockholders approved the 2011 Stock Option Plan for Non-Employee Directors (“2011 Plan”). Under the 2011 Plan, non-qualified stock options to purchase up to 150,000 shares of common stock are available for grant to non-employee directors at exercise prices of not less than fair market value of the underlying common stock on the date of grant. Options to purchase 4,000 shares of the Company’s common stock are granted automatically to each non-employee director on the last day that the Company’s common stock is traded in November of each year from 2011 to 2015. Each option will expire five years after the date the option is granted and options vest at the rate of 25% per year commencing one year after the date of grant. At September 30, 2011, 150,000 shares were available for grant under the 2011 Plan.
The fair value of each stock option granted under the above plans was estimated on the date of grant using the Black-Scholes option pricing model with the following average assumptions:
                 
    For the Six Months  
    Ended September 30,  
    2011     2010  
 
               
Expected dividend yield at time of grant
    3.29 %     3.11 %
Expected stock price volatility
    54 %     55 %
Risk-free interest rate
    2.39 %     2.63 %
Expected life of option (in years)
    5.1       4.7  
Expected volatilities are based on historical volatility of the Company’s common stock. The expected life of the option is estimated using historical data pertaining to option exercises and employee terminations. The risk-free interest rate is based on U.S. Treasury yields in effect at the time of grant.
The weighted average fair value of stock options granted during the six months ended September 30, 2011 and 2010 was $6.88 and $6.99, respectively. The weighted average fair value of restricted stock units granted during the six months ended September 30, 2011 and 2010 was $16.25 and $16.94, respectively.
As of September 30, 2011, there was $1,661,000 of total unrecognized compensation cost related to non-vested stock option awards granted under the Company’s equity incentive plans which is expected to be recognized over a weighted average period of 2.7 years. As of September 30, 2011, there was $2,410,000 of total unrecognized compensation cost related to non-vested RSUs granted under the Company’s equity incentive plans which is expected to be recognized over a weighted average period of 2.5 years.
Compensation cost related to stock options and RSUs recognized in operating results (included in selling, general and administrative expenses) was $493,000 and $505,000 in the quarters ended September 30, 2011 and 2010, respectively, and was $956,000 and $966,000 for the six months ended September 30, 2011 and 2010, respectively.
