|STOCK-BASED COMPENSATION                                                      | STOCK-BASED COMPENSATIONThe Company grants stock-based awards under its 2006 Stock Incentive Plan (the “2006 Plan”). The 2006 Plan replaced the Company’s 2003 Stock Option Plan (the “2003 Plan”) and certain other prior stock option plans. The 2003 Plan and these other plans terminated upon the 2006 Plan’s initial stockholder approval in June 2006, other than with respect to outstanding options, which continued to be governed by the applicable prior plan. Only awards under the 2003 Plan continue to be outstanding insofar as these prior plans are concerned. Shares issued as a result of stock-based compensation transactions generally have been funded with the issuance of new shares of the Company’s common stock.The Company may grant the following types of incentive awards under the 2006 Plan (i) non-qualified stock options (“NQs”); (ii) incentive stock options (“ISOs”); (iii) stock appreciation rights; (iv) restricted stock; (v) restricted stock units (“RSUs”); (vi) performance shares and performance share units (“PSUs”); and (vii) other stock-based awards. Each award granted under the 2006 Plan is subject to an award agreement that incorporates, as applicable, the exercise price, the term of the award, the periods of restriction, the number of shares to which the award pertains, applicable performance period(s) and performance measure(s), and such other terms and conditions as the plan committee determines.ThroughAugust 2, 2015, the Company has granted under the 2006 Plan (i) service-based NQs, RSUs and restricted stock; (ii) contingently issuable PSUs; and (iii) RSUs that are intended to satisfy the performance-based condition for deductibility under Section 162(m) of the Internal Revenue Code. According to the terms of the 2006 Plan, for purposes of determining the number of shares available for grant, with the exception of the Warnaco employee replacement awards discussed below, each share underlying a stock option award reduces the number available byoneshare and each share underlying a restricted stock award, RSU or PSU reduces the number available bytwoshares. Each share underlying a Warnaco employee replacement stock option, restricted stock, RSU or PSU reduces the number available by one share. The per share exercise price of options granted under the 2006 Plan cannot be less than the closing price of the common stock on the date of grant (the business day prior to the date of grant for awards granted prior to September 21, 2006).The Company currently has service-based NQs outstanding under the 2003 Plan. Such stock options were granted with an exercise price equal to the closing price of the Company’s common stock on the business day immediately preceding the date of grant.Under the terms of the merger agreement in connection with the Warnaco acquisition, each outstanding award of stock options, restricted stock and restricted stock units made by Warnaco was assumed by the Company in 2013 and converted into an award of the same type, and subject to the same terms and conditions, but payable in shares of Company common stock. The replacement stock options are generally exercisable inthreeequal annual installments commencingoneyear after the date of original grant and the replacement RSUs and restricted stock awards generally vestthreeyears after the date of original grant, principally on a cliff basis. The Company accounted for the replacement awards as a modification of the existing awards. As such, a new fair value was assigned to the awards, a portion of which is included as part of the merger consideration. The merger consideration of$39.8million was determined by multiplying the estimated fair value of the Warnaco awards outstanding at the effective time of the Warnaco acquisition, net of the estimated value of awards to be forfeited, by the proportionate amount of the vesting period that had lapsed as of the acquisition date. The remaining fair value, net of estimated forfeitures, is being expensed over the awards’ remaining vesting periods.Net income for thetwenty-six weeks endedAugust 2, 2015andAugust 3, 2014included $20.4million and $24.4million, respectively, of pre-tax expense related to stock-based compensation, with recognized income tax benefits of $5.0million and $6.2million, respectively.Stock options currently outstanding, with the exception of the Warnaco employee replacement awards discussed above, are generally cumulatively exercisable infourequal annual installments commencing one year after the date of grant. The vesting of such options outstanding is also generally accelerated upon retirement (as defined in the applicable plan). Such options are generally granted with a10-year term.The Company estimates the fair value of stock options granted at the date of grant using the Black-Scholes-Merton model. The estimated fair value of the options, net of estimated forfeitures, is expensed over the options’ vesting periods.The following summarizes the assumptions used to estimate the fair value of service-based stock options granted during thetwenty-six weeks endedAugust 2, 2015andAugust 3, 2014:Twenty-Six Weeks Ended8/2/158/3/14Weighted average risk-free interest rate1.54%2.15%Weighted average expected option term (in years)6.256.25Weighted average Company volatility36.32%44.12%Expected annual dividends per share$0.15$0.15Weighted average grant date fair value per option$40.23$56.21The risk-free interest rate is based on United States Treasury yields in effect at the date of grant for periods corresponding to the expected option term. The expected option term represents the weighted average period of time that options granted are expected to be outstanding, based on vesting schedules and the contractual term of the options. Company volatility is based on the historical volatility of the Company’s common stock over a period of time corresponding to the expected option term. Expected dividends are based on the Company’s common stock cash dividend rate at the date of grant.The Company has continued to utilize the simplified method to estimate the expected term for its “plain vanilla” stock options granted due to a lack of relevant historical data resulting, in part, from changes in the pool of employees receiving option grants, mainly due to acquisitions. The Company will continue to evaluate the appropriateness of utilizing such method.Service-based stock option activity for thetwenty-six weeks endedAugust 2, 2015was as follows:(In thousands, except per option data)OptionsWeighted Average Exercise PricePer OptionOutstanding at February 1, 20151,472$64.14Granted172107.13Exercised10949.84Cancelled14107.57Outstanding at August 2, 20151,521$69.64Exercisable at August 2, 20151,136$55.51RSUs granted to employees, with the exception of the Warnaco employee replacement awards, generally vest inthreeannual installments of25%,25%and50%commencingtwoyears after the date of grant. Service-based RSUs granted to non-employee directors vest in fulloneyear after the date of grant. The underlying RSU award agreements (excluding agreements for non-employee director awards made during or after 2010) generally provide for accelerated vesting upon the award recipient’s retirement (as defined in the 2006 Plan). The fair value of service-based RSUs, with the exception of the Warnaco employee replacement awards, is equal to the closing price of the Company’s common stock on the date of grant and is expensed, net of estimated forfeitures, over the RSUs’ vesting periods.RSU activity for thetwenty-six weeks endedAugust 2, 2015was as follows:(In thousands, except per RSU data)RSUsWeighted Average Grant Date Fair Value Per RSUNon-vested at February 1, 2015640$107.42Granted295104.53Vested19586.22Cancelled53113.53Non-vested at August 2, 2015687$111.73The Company’s restricted stock awards consist solely of awards to Warnaco employees that were replaced with the Company’s restricted stock as of the effective time of the acquisition. The fair value of restricted stock with respect to awards for which the vesting period had not lapsed as of the acquisition date was equal to the closing price of the Company’s common stock on February 12, 2013 and is expensed, net of forfeitures, over the vesting period.Restricted stock activity for thetwenty-six weeks endedAugust 2, 2015was as follows:(In thousands, except per share data)Restricted StockWeighted Average Grant Date Fair Value Per ShareNon-vested at February 1, 201520$120.72Granted——Vested17120.72Cancelled1120.72Non-vested at August 2, 20152$120.72The Company granted contingently issuable PSUs to certain of the Company’s senior executives during the first quarter of each of 2012, 2013 and 2014. These awards were (are) subject to achievement of an earnings per share and, in the case of the awards made in 2012, a return on equity goal for the two-year performance period beginning with the year of grant and a service period ofoneyear beyond the certification of performance. For the awards granted in the first quarter of 2014, the final number of shares that will be earned, if any, is contingent upon the Company’s achievement of goals for the performance period based on earnings per share growth during the performance cycle. For the awards granted in the first quarter of 2013, the two year performance period has ended and the holders earned an aggregate of26thousand shares, which will vest and be paid out subject to and following the additional one-year service period. The holders of the awards granted in the first quarter of 2012 earned an aggregate of54thousand shares, which were paid out in the first quarter of 2015. For such awards, the Company records expense ratably over each applicable vesting period based on fair value and the Company’s current expectations of the probable number of shares that will ultimately be issued. The fair value of these contingently issuable performance share units is equal to the closing price of the Company’s common stock on the date of grant, reduced for the present value of any dividends expected to be paid on the Company’s common stock during the performance cycle, as these contingently issuable performance share units do not accrue dividends prior to the completion of the performance cycle.The Company granted contingently issuable PSUs to certain of the Company’s executives during the second quarter of 2013 and to certain of the Company’s senior executives during the first quarter of 2015 subject to a performance period ofthreeyears. For the awards granted in the second quarter of 2013 and the first quarter of 2015, the final number of shares that will be earned, if any, is contingent upon the Company’s achievement of goals for the applicable performance period, of which 50 percent is based upon the Company’s absolute stock price growth during the applicable performance period and 50 percent is based upon the Company’s total shareholder return during the applicable performance period relative to other companies included in the S&P 500 as of the date of grant. For such awards, because the awards are subject to market conditions, the Company records expense ratably over the applicable vesting period, net of estimated forfeitures, regardless of whether the market condition is satisfied. The fair value of the awards granted in the first quarter of 2015 was established on the grant date using the Monte Carlo simulation model, which was based on the following assumptions:Risk-free interest rate0.90%Expected Company volatility29.10%Expected annual dividends per share$0.15Grant date fair value per performance share unit$101.23Performance share activity for thetwenty-six weeks endedAugust 2, 2015was as follows:(In thousands, except per share data)Performance SharesWeighted Average Grant Date Fair Value Per ShareNon-vested at February 1, 2015553$119.95Granted46101.23Vested5488.52Cancelled45121.91Non-vested at August 2, 2015500$121.45The Company receives a tax deduction for certain transactions associated with its stock plan awards. The actual income tax benefits realized from these transactions for thetwenty-six weeks endedAugust 2, 2015andAugust 3, 2014were $9.0million and $10.5million, respectively. Of those amounts, $3.4million and $4.6million, respectively, were reported as excess tax benefits. Excess tax benefits arise when the actual tax benefit resulting from a stock plan award transaction exceeds the tax benefit associated with the grant date fair value of the related stock award.
