Stock-Based Compensation

9. STOCK-BASED COMPENSATION

The Company has one stock-based compensation plan, the 2005 Stock Incentive Plan (the "2005 Plan"), which was amended by its shareholders on May 7, 2008. The 2005 Plan is administered by the Compensation Committee of the Company's Board of Directors. Stock-based compensation is granted to officers, directors and certain key employees in accordance with the provisions of the 2005 Plan. The 2005 Plan provides for grants of stock options, stock appreciation rights ("SARs"), restricted stock and performance share awards. As of March 31, 2012, the total aggregate number of shares of the Company's common stock that may be issued under the 2005 Plan is 3,150,000.

The fair value of each SAR is estimated on the date of grant using a Black-Scholes option-pricing formula. For SARs issued in the three months ended March 31, 2012 and 2011, respectively, the assumptions shown in the following table were used:

		Stock Awards Grante			Stock Awards Grante

Weighted-average fair value of grants	$	14.01		$	14.56
Dividend yield		0	%		0	%
Average risk-free interest rate		0.8	%		2.0	%
Expected term (years)		5			5
