Share-based Compensation [Abstract]
Share-based Compensation	Share-Based Compensation In the first quarter of fiscal 2018, as part of the annual awards under the Company’s Long-Term Incentive Plan, the Compensation Committee of the Company’s Board of Directors (“Compensation Committee”) granted 252,865 restricted stock units (“RSUs”) and 246,161 performance share awards to the Company’s key employees and officers under the Company’s 1993 Amended and Restated Stock Incentive Plan (“SIP”). The RSUs have a five-year term and vest 20% per year commencing October 31, 2018. The aggregate fair value of all of the RSUs granted was based on the market closing price of the underlying Class A common stock on the grant date and totaled $7 million. The compensation expense associated with the RSUs is recognized over the requisite service period of the awards, net of forfeitures. The performance share awards comprise two separate and distinct awards with different vesting conditions. The Compensation Committee granted 119,763 performance share awards based on a relative Total Shareholder Return (“TSR”) metric over a performance period spanning November 14, 2017 to August 31, 2020. Award share payouts range from a threshold of 50% to a maximum of 200% based on the relative ranking of the Company’s TSR among a designated peer group of 16 companies. The TSR award stipulates certain limitations to the payout in the event the payout reaches a defined ceiling level or the Company’s TSR is negative. The TSR awards contain a market condition and, therefore, once the award recipients complete the requisite service period, the related compensation expense based on the grant-date fair value is not changed, regardless of whether the market condition has been satisfied. The estimated fair value of the TSR awards at the date of grant was $3 million. The Company estimated the fair value of the TSR awards using a Monte-Carlo simulation model utilizing several key assumptions including expected Company and peer company share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The remaining 126,398 performance share awards have a three-year performance period consisting of the Company’s 2018, 2019 and 2020 fiscal years. The performance targets are based on the Company’s return on capital employed over the three-year performance period, with award payouts ranging from a threshold of 50% to a maximum of 200%. The fair value of the awards granted was based on the market closing price of the underlying Class A common stock on the grant date and totaled $3 million. The compensation expense associated with performance share awards is recognized over the requisite service period, net of forfeitures. Performance share awards will be paid in Class A common stock as soon as practicable after the end of the requisite service period and vesting date of October 31, 2020. In the second quarter of fiscal 2018, the Company granted deferred stock units (“DSUs”) to each of its non-employee directors under the Company’s SIP. Each DSU gives the director the right to receive one share of Class A common stock at a future date. The grant included an aggregate of 20,748 shares that will vest in full on the day before the Company’s 2019 annual meeting of shareholders, subject to continued Board service. The total value of these awards at the grant date was $1 million.
