Note 2. Stock-Based Compensation

The Company has a 2001 Stock Award and Incentive Plan (the "Plan"), which provides for grants of incentive and non-qualified stock options, restricted stock, stock appreciation rights, stock awards or performance unit awards. The Plan is administered by the Compensation Committee of the Board of Directors. Stock options granted under the Plan generally have a ten year term. The exercise price for stock options are at prices at or above the fair market value of the common stock on the date of the grant, and each award of stock options will vest ratably over a specified period, generally three years.

Stock-based compensation expense is recognized in the consolidated financial statements for stock options based on the grant date fair value.

Net income for years ended 2013, 2012 and 2011 include $2.8 million, $2.0 million and $2.7 million pre-tax compensation costs, respectively, related to stock option expense as a component of marketing and administrative expenses. All stock option expense is recognized in the consolidated statements of operations. The related tax benefit included in the statement of income on the non-qualified stock options was $1.1 million, $0.8 million and $1.1 million for 2013, 2012 and 2011, respectively.

The benefits of tax deductions in excess of the tax benefit from compensation costs that were recognized or would have been recognized are classified as financing inflows on the consolidated statement of cash flows.

Stock Options

The fair value of options granted is estimated on the date of grant using the Black-Scholes valuation model. Compensation expense is recognized only for those options expected to vest, with forfeitures estimated at the date of grant based on the Company's historical experience and future expectations. The forfeiture rate assumption used for the periods ended December 31, 2013 and 2012 was 7.50% and 7.31%, respectively.

The weighted average grant date fair value for stock options granted during the years ended December 31, 2013, 2012 and 2011 was $15.83, $10.74 and $11.03, respectively. The weighted average grant date fair value for stock options vested during 2013, 2012 and 2011 was $10.29, $8.57 and $7.58, respectively. The total intrinsic value of stock options exercised during the years ended December 31, 2013, 2012 and 2011 was $10.0 million, $3.3 million and $1.7 million, respectively.

The fair value for stock awards was estimated at the date of grant using the Black-Scholes option valuation model with the following weighted average assumptions for the years ended December 31, 2013, 2012 and 2011:

	2013			2012			2011
Expected life (years)		6.9			6.9			6.3
Interest rate		1.22	%		1.36	%		2.46	%
Volatility		37.82	%		31.26	%		30.93	%
Expected dividend yield		0.48	%		0.31	%		0.31	%

The expected term of the options represents the estimated period of time until exercise and is based on historical experience of similar awards, based upon contractual terms, vesting schedules, and expectations of future employee behavior. The expected stock-price volatility is based upon the historical and implied volatility of the Company's stock. The interest rate is based upon the implied yield on U.S. Treasury bills with an equivalent remaining term. Estimated dividend yield is based upon historical dividends paid by the Company.
