Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Share-Based Compensation | Share-Based Compensation For each of the three month periods ended March 31, 2012 and 2011, share-based compensation cost recognized was $50,000. The recognized tax benefit for stock option compensation expense was $9,000 for each of the three month periods ended March 31, 2012 and 2011. The Company bases the fair value of the options granted on the date of grant using a Black-Scholes Merton option pricing model that uses assumptions based on expected option life and the level of estimated forfeitures, expected stock volatility, risk free interest rate, and dividend yield. The expected term of the Company’s options was based on the Company's own historical experience. Stock volatility is based on the historical volatility of the Company’s stock. The risk-free rate is based on the U. S. Treasury yield curve for the periods within the contractual life of the options in effect at the time of grant. The compensation cost for options granted is based on the weighted average grant date fair value per share. No options to purchase shares of the Company’s common stock were issued in the first three months of 2012 and 2011 from any of the Company’s stock based compensation plans. A summary of the combined activity of the Company’s Stock Based Compensation Plans for the three month period ended March 31, 2012 follows:
