In 2016, the Company adopted ASC Topic No. 2016-09. See Note 2, "Summary of Significant Accounting Policies — Recently Adopted Accounting Standards."" id="sjs-B4">Stock Compensation Plans The Company established the 2004 Omnibus Stock and Incentive Plan (the "2004 Omnibus Plan") in December 2004 and reserved 3,500,000 shares of $0.01 par value common stock ("Common Stock") for issuance under the Omnibus Plan. Pursuant to the terms of the 2004 Omnibus Plan, the compensation committee of the Company's Board of Directors may grant various types of equity-based compensation awards, including incentive and nonqualified stock options, SARs, restricted stock, RSUs, RSUs with performance conditions and performance units, in addition to certain cash-based awards. All grants under the Omnibus Plan will be made at fair market value and no grant may be repriced. In general, the options expire 10 years from the date of grant and vest over a 3 -year service period. At the 2013 Annual Meeting of Stockholders, the Company's stockholders approved an amendment and restatement of the 2004 Omnibus Plan (as amended and restated the "2013 Omnibus Plan"). The amendment and restatement authorized the Company to reserve an additional 1,577,000 shares of Common Stock for future issuance. As of December 31, 2016 , the Company had 950,000 shares of Common Stock reserved for future issuance under the 2013 Omnibus Plan. As of December 31, 2016 , the number of shares available for future issuance was reduced by approximately 17,000 shares for outstanding SARs where the closing market price for the Company's common stock was greater than the exercise price of the SAR. The Company accounts for stock-based compensation pursuant to the fair value recognition provisions of ASC Topic 718, Compensation — Stock Compensation ("ASC Topic 718"). Valuation and Expense Information Under ASC Topic 718 Substantially all stock-based compensation expense has been recorded in selling, general and administrative expenses. The following table summarizes stock-based compensation costs and related income tax benefits. Year Ended December 31, 2016 2015 2014 Stock-based compensation expense $ 5.8 $ 6.5 $ 6.0 Income tax benefit (2.2 ) (2.5 ) (2.3 ) Stock-based compensation, net of income tax benefit $ 3.6 $ 4.0 $ 3.7 The following table summarizes total compensation costs related to the Company's equity awards and amounts recognized in the year ended December 31, 2016 . Stock Options Performance Unrecognized compensation cost — December 31, 2015 $ 0.8 $ 1.6 Grant date fair value current year grants 1.5 4.2 Compensation expense recognized (1.7 ) (4.1 ) Unrecognized compensation cost — December 31, 2016 $ 0.6 $ 1.7 Expected amortization period (in years) 1.7 1.5 Stock Options/SARs In August 2014, the Compensation Committee of the Board of Directors approved the conversion of approximately 545,000 outstanding non-qualified stock options held by U.S. employees and U.S. non-employee directors to an equal number of SARs. Upon exercise, the holder of an SAR will receive common shares equal to the number of SARs exercised multiplied by a fraction where the numerator is equal to the market price at the time of exercise minus the exercise price of the SAR and the denominator is equal to the market price at the time of exercise. The SARs can only be settled for shares of Common Stock and the Company will not receive any cash proceeds upon exercise. All other contractual terms of the SARs are unchanged from those of the converted non-qualified stock options. At the date of conversion the fair value of the SARs was equal to the fair value of the stock options exchanged. As a result, the Company did not recognize any additional compensation expense due to the conversion. The following tables present information regarding stock options awarded during the years ended December 31, 2016 , 2015 and 2014 . 2016 2015 2014 Nonqualified stock options granted 113,935 87,930 95,670 Per share weighted-average exercise price $ 58.03 $ 59.72 $ 43.17 Per share weighted-average grant date fair value $ 13.51 $ 16.47 $ 12.72 The weighted-average grant date fair value for stock options granted for the years ended December 31, 2016 , 2015 and 2014 was estimated using the Black-Scholes option valuation model with the following assumptions: 2016 2015 2014 Expected term in years 5.8 5.8 5.9 Risk free interest rate 1.8 % 1.4 % 1.9 % Volatility 32.1 % 34.4 % 36.5 % Dividend yield 3.0 % 2.0 % 2.2 % Expected volatility and the expected term were estimated by reference to the historical stock price performance of the Company and historical data for the Company's stock option awards, respectively. The risk-free interest rate was based on the yield on U.S. Treasury bonds with a remaining term approximately equal to the expected term of the stock option awards. Forfeitures were estimated at the date of grant. During the year ended December 31, 2012, the Company awarded nonqualified stock options to its President and Chief Executive Officer to purchase 125,000 shares of Common Stock (subject to forfeiture due to termination of employment and other conditions). The exercise price of such nonqualified stock option awards was $24.09 per share and the options expire in ten years . As of December 31, 2016 , 100 percent of the option award had been earned. The grant date fair value of such stock options was $9.55 per share and was estimated using a "Monte Carlo" simulation valuation model.
