Share-Based Compensation | Share-Based Compensation The Company records the fair value of share-based payments to employees in the unaudited Consolidated Statements of Income and Comprehensive Income as compensation expense, net of forfeitures, over the requisite service period. Share-Based Compensation Plans The following summarizes share-based compensation expense: Thirteen Weeks Ended April 30, 2016 May 2, 2015 (in thousands) Restricted stock units and restricted stock $ 3,305 $ 2,607 Stock options 1,063 1,244 Total share-based compensation $ 4,368 $ 3,851 The stock compensation related income tax benefit recognized by the Company during the thirteen weeks ended April 30, 2016 and thirteen weeks ended May 2, 2015 was $5.5 million and $2.7 million , respectively. Stock Options During the thirteen weeks ended April 30, 2016 , the Company granted stock options under the 2010 Plan. The fair value of the stock options is determined using the Black-Scholes-Merton option-pricing model as described later in this note. Stock options granted in 2016 under the 2010 Plan vest 25% per year over four years or upon reaching retirement eligibility, defined as providing 10 years of service and being at least 55 years old. These options have a ten year contractual life. The expense for stock options is recognized using the straight-line attribution method. The Company's activity with respect to stock options during the thirteen weeks ended April 30, 2016 was as follows: Number of Shares Grant Date Weighted Average Exercise Price Per Share Weighted-Average Remaining Contractual Life (in years) Aggregate Intrinsic Value (in thousands, except per share amounts and years) Outstanding, January 31, 2016 3,446 $ 18.31 Granted 229 $ 21.14 Exercised (156 ) $ 17.35 Forfeited or expired (29 ) $ 20.13 Outstanding, April 30, 2016 3,490 $ 18.52 6.0 $ 2,793 Expected to vest at April 30, 2016 632 $ 17.96 8.6 $ 804 Exercisable at April 30, 2016 2,820 $ 18.63 5.4 $ 1,962 The following table provides additional information regarding the Company's stock options: Thirteen Weeks Ended April 30, 2016 May 2, 2015 (in thousands, except per share amounts) Weighted average grant date fair value of options granted (per share) $ 9.50 $ 7.76 Total intrinsic value of options exercised $ 536 $ — As of April 30, 2016 , there was approximately $3.8 million of total unrecognized compensation expense related to stock options, which is expected to be recognized over a weighted average period of approximately 1.8 years. The Company uses the Black-Scholes-Merton option-pricing model to value stock options granted to employees. The Company's determination of the fair value of stock options is affected by the Company's stock price as well as a number of subjective and complex assumptions. These assumptions include the risk-free interest rate, the Company's expected stock price volatility over the term of the award, expected term of the award, and dividend yield. The fair value of stock options was estimated at the grant date using the Black-Scholes-Merton option pricing model with the following weighted-average assumptions: Thirteen Weeks Ended April 30, 2016 May 2, 2015 Risk-free interest rate (1) 1.60 % 1.59 % Price volatility (2) 43.15 % 47.93 % Expected term (years) (3) 6.54 6.25 Dividend yield (4) — — (1) Represents the yield on U.S. Treasury securities with a term consistent with the expected term of the stock options. (2) For the first two years following the initial public offering of the Company's common stock, this was based on the historical volatility of selected comparable companies over a period consistent with the expected term of the stock options because the Company had a limited history of being publicly traded. Comparable companies were selected primarily based on industry, stage of life cycle, and size. Beginning in May 2012, the Company began using its own volatility as an additional input in the determination of expected volatility. (3) Beginning in 2016, the Company calculated the expected term assumption using the midpoint scenario, which combines historical exercise data with hypothetical exercise data for outstanding options, as the Company believes this data currently represents the best estimate of the expected term of new employee options. (4) The Company does not currently plan on paying regular dividends. Restricted Stock Units and Restricted Stock During the thirteen weeks ended April 30, 2016 , the Company granted restricted stock units (“RSUs”) under the 2010 Plan, including 0.3 million RSUs with performance conditions. The fair value of RSUs is determined based on the Company's closing stock price on the day prior to the grant date in accordance with the 2010 Plan. The expense for RSUs without performance conditions is recognized using the straight-line attribution method. The expense for RSUs with performance conditions is recognized using the graded vesting method based on the expected achievement of the performance conditions. The RSUs with performance conditions are also subject to time-based vesting. All of the RSUs granted during the thirteen weeks ended April 30, 2016 that are earned based on the achievement of performance criteria will vest on April 15, 2019. RSUs without performance conditions vest ratably over four years. The Company's activity with respect to RSUs and restricted stock, including awards with performance conditions, for the thirteen weeks ended April 30, 2016 was as follows: Number of Shares Grant Date Weighted Average Fair Value Per Share (in thousands, except per share amounts) Unvested, January 31, 2016 2,212 $ 16.66 Granted (1) 926 $ 21.14 Vested (713 ) $ 17.22 Forfeited (105 ) $ 17.44 Unvested, April 30, 2016 2,320 $ 18.24 (1) Approximately 0.3 million RSUs with three -year performance conditions are included in this amount, which represents 100% of the number of shares granted. This is based on current estimates against predefined financial performance targets ranging from 0% to 200% . The total fair value/intrinsic value of RSUs and restricted stock that vested during the thirteen weeks ended April 30, 2016 was $12.3 million . As of April 30, 2016 , there was approximately $33.1 million of total unrecognized compensation expense related to unvested RSUs and restricted stock, which is expected to be recognized over a weighted-average period of approximately 2.2 years. |
