Stock-Based Compensation
STOCK-BASED COMPENSATION
The Company’s stock incentive plan (the “Plan”) provides for issuance of up to 10,400,000 shares of the Company’s Common Stock, of which 2,187,824 shares were available for future grants under the Plan at December 31, 2013. The Plan allows for grants of incentive stock options, non-statutory stock options, restricted stock awards, restricted stock units and other stock-based or cash-based awards. The Company uses original issuance shares to satisfy share-based payments.

The Company realized a tax benefit for the deduction from stock-based award transactions of $4,793,000, $3,410,000, and $4,702,000 for the years ended December 31, 2013, 2012 and 2011, respectively.
Stock Options
Options to purchase the Company’s common stock are granted at exercise prices equal to or greater than the fair market value of the Company’s common stock on the date of grant. Options granted after 2000 and before 2009 generally vest and become exercisable over a period of four years (25 percent on the first anniversary date following the date of grant and monthly thereafter) and expire ten years from the date of the grant, with the exception of most options granted in 2005. Most options granted in 2005 vested and became exercisable one year from the date of grant and expire ten years from the date of grant. Options granted after 2008 generally vest and become exercisable ratably on an annual basis over a period of four years and expire ten years from the date of the grant.
The Company estimates the fair value of stock options using the Black-Scholes model. Key inputs and assumptions used to estimate the fair value of stock options include the exercise price of the award, the expected option term, expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and the Company’s expected annual dividend yield. The option's expected term is derived from historical option exercise behavior and the option's terms and conditions, which the Company believes provide a reasonable basis for estimating an expected term. The expected volatility is estimated based on observations of the Company's historical volatility over the most recent term commensurate with the expected term. The risk-free interest rate is based on the U.S. Treasury yield approximating the expected term. The dividend yield is based on the anticipated cash dividend payouts. Assumptions are evaluated and revised as necessary to reflect changes in market conditions and the Company’s experience. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by people who receive equity awards.

During the year ended December 31, 2011, the Company granted two stock option awards totaling 53,720 shares that vest 100% on the fifth anniversary of the grant date. Because the Company did not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term for these grants, the Company utilized the simplified method in developing an estimate of the expected term of these options.

The aggregate intrinsic value in the table above represents pre-tax intrinsic value that would have been realized if all options had been exercised on the last business day of the period indicated, based on the Company’s closing stock price on that day.
Total stock option compensation expense for the years ended December 31, 2013, 2012 and 2011 was $3,479,000, $3,180,000 and $3,550,000, respectively. At December 31, 2013, unrecognized costs related to stock options totaled approximately $5,637,000, before any related tax benefit. The unrecognized costs related to stock options are being amortized over the related vesting period using the straight-line attribution method. Unrecognized costs related to stock options at December 31, 2013 are expected to be recognized over a weighted average period of 2.23 years. The aggregate intrinsic value of stock options exercised was $7,491,000, $5,517,000 and $4,906,000 for the years ended December 31, 2013, 2012 and 2011, respectively. The total cash received as a result of stock option exercises for the years ended December 31, 2013, 2012 and 2011 was $19,537,000, $14,600,000 and $10,991,000, respectively.
Restricted Stock Units
Service-based restricted stock units are granted at no cost to key employees, and shares granted prior to 2009 generally vest over three years from the date of grant. Service-based restricted stock units granted after 2008 generally vest over a period of four years. Performance-based restricted stock units are granted at no cost to certain members of the Company’s senior executive team, excluding the Chairman and the President and Chief Executive Officer. Performance-based restricted stock units granted prior to 2010 generally vest over a performance period of between two and one-half and three years with an additional required service period of one year. Performance-based restricted stock units granted after 2009 generally vest over a performance period of between two and three years. Restricted stock units vest in accordance with the terms and conditions established by the Compensation Committee of the Board of Directors, and are based on continued service and, in some instances, on individual performance and/or Company performance. For the majority of restricted stock units granted, the number of shares issued on the date the restricted stock units vest is net of the minimum statutory withholding requirements that the Company pays in cash to the appropriate taxing authorities on behalf of its employees. For the years ended December 31, 2013, 2012 and 2011, the Company withheld 41,683, 30,299 and 48,059 shares, respectively, to satisfy $2,291,000, $1,486,000 and $2,974,000 of employees’ tax obligations, respectively.
The fair value of service-based and performance-based restricted stock units is discounted by the present value of the estimated future stream of dividends over the vesting period using the Black-Scholes model. The relevant inputs and assumptions used in the Black-Scholes model to compute the discount are the vesting period, expected annual dividend yield and closing price of the Company’s common stock on the date of grant.
