Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Average values and weighted-average assumptions used for option grants

The Company continues to use the Black-Scholes-Merton option pricing model and amortizes compensation expense over the requisite service period of the grant. The methodology used in 2012 to derive the assumptions used in the valuation model is consistent with that used in prior years. Beginning in March 2012, the Company declared its first quarterly cash dividend and, as a result, the expected dividend yield has changed. See Note K, Stockholders’ Equity, for more information regarding dividends. The expected dividend yields are based on the per share dividend declared by the Company’s Board of Directors.

The following average values and weighted-average assumptions were used for option grants. 

	2012			2011			2010
Black-Scholes-Merton Value	$	7.52		$	11.08		$	7.45
Dividend yield	1.6		%	0.0		%	0.0		%
Risk-free interest rate	0.5		%	0.9		%	1.4		%
Expected volatility	37.3		%	41.9		%	47.4		%
Expected life (in years)	3.6			3.5			3.5
