Stock Based Compensation [Abstract]  
Stock Based Compensation
(15) STOCK BASED COMPENSATION

The Company measures compensation costs related to share-based transactions at the grant date, based on the fair value of the award, and recognizes them as expense over the requisite service period.

For the year ended March 31, 2012, the Company recorded pre-tax compensation expense for stock-based incentive awards of $1,062 which increased selling, general and administrative expenses by $707 and cost of revenues by $355 and had an associated tax benefit of $393. The impact on basic and diluted net income per share for the year ended March 31, 2012 was $0.05.

For the year ended March 31, 2011, the Company recorded pre-tax compensation expense for stock-based incentive awards of $2,345 which increased selling, general and administrative expenses by $2,144 and cost of revenues by $201 and had an associated tax benefit of $656. The impact on basic and diluted net income per share for the year ended March 31, 2011 was $0.13.

 

For the year ended March 31, 2010, the Company recorded pre-tax compensation expense for stock-based incentive awards of $2,253 which increased selling, general and administrative expenses by $2,104 and cost of revenues by $149 and had an associated tax benefit of $518. The impact on basic and diluted net income per share for the year ended March 31, 2010 was $0.14.

The Company calculates the value of each employee stock option, estimated on the grant date, using the Black-Scholes model and the following weighted average assumptions:

 

     2012     2011     2010  

Expected life (years)

     5        5        5   

Risk-free interest rate

     1.8 %      2.3 %      2.1 % 

Expected volatility

     56.7 %      52.2 %      49.3 % 

Dividend yield

     0.9 %      2.0 %      1.9 % 

The Company estimated volatility based on the historical volatility of its common stock. The risk-free interest rate is based on the U.S. Treasury yield for a term consistent with the expected life of the options in effect at the time of the grant. The dividend yield assumption is based on the Company's history and expectation of dividend payouts. The expected life of the options represents the weighted-average period the stock options are expected to remain outstanding and is based on review of historical exercise behavior of option grants with similar vesting periods. The Company uses an estimated forfeiture rate based on historical data. The forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

 

Stock  Options

As of March 31, 2012, the Company reserved 238 shares for future issuance to key employees and directors under the Company's stock option plans. Stock options granted under the plans enable the holder to purchase common stock at an exercise price not less than the market value on the date of grant and will expire not more than ten years after the date of grant. The applicable options vest ratably over a three to five year period. A summary of the changes in the options outstanding for years ended March 31, 2012, 2011 and 2010 is shown below:

Restricted Stock

The Company's stock option plans also provide for the issuance of restricted stock to certain employees and directors. The Company has reserved 229 restricted shares of common stock for future issuance to non-employee directors under the 2006 Director Equity Compensation Plan (the 2006 Director Plan). Restricted stock grants under these plans typically vest over a three to five year period. The cost of these awards is determined using the fair value of the Company's common stock on the date of the grant and is recognized on a straight-line basis over the period the restrictions lapse. A summary of the changes in restricted shares for the year ended March 31, 2012, 2011 and 2010 is shown below:
