Share-based Compensation [Abstract]
Share-Based Compensation	Share-Based Compensation In the first quarter of fiscal 2016, 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 the first half of the fiscal 2016 annual award consisting of 203,728 restricted stock units ("RSUs") and 201,702 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, 2016. In addition, in the first quarter of fiscal 2016 the Compensation Committee granted 48,163 RSUs with a two-year vesting term and no retirement-eligibility provisions under the SIP. 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 $4 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 are comprised of two separate and distinct awards with different vesting conditions. The Compensation Committee granted 99,860 of the performance share awards based on a relative Total Shareholder Return ("TSR") metric over a performance period spanning November 9, 2015 to August 31, 2018. Award share payouts range from 0% 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 $2 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 101,842 performance share awards have a three-year performance period consisting of the Company’s fiscal 2016, 2017 and 2018. The performance targets are based on the Company's cash flow return on investment ("CFROI") over the three-year performance period, with award payouts ranging from 0% 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 $2 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, 2018. In the second quarter of fiscal 2016, the Company granted deferred stock units ("DSU") to each of its non-employee directors under the Company's 1993 Stock Incentive Plan. 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 57,780 shares that will vest on the day before the Company's 2017 annual meeting, subject to continued Board service. The total value of these awards at the grant date was $1 million. John Carter, the Company's Chairman, and Tamara Lundgren, President and Chief Executive Officer, receive compensation pursuant to their employment agreements and do not receive DSUs. In the third quarter of fiscal 2016, the Compensation Committee granted the second half of the fiscal 2016 annual award consisting of 157,403 RSUs and 152,221 performance share awards consisting of 73,546 TSR awards and 78,675 CFROI awards to the Company's key employees and officers under its SIP with terms substantially similar to the awards granted in the first quarter of fiscal 2016, as described above in this Note, except that the performance period for the TSR awards started on April 27, 2016 and for the CFROI awards on March 1, 2016. The fair values of RSUs, TSR awards and CFROI awards granted in the third quarter of fiscal 2016 were $3 million, $2 million and $2 million, respectively.

Share-Based Compensation

In the first quarter of fiscal 2016, 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 the first half of the fiscal 2016 annual award consisting of 203,728 restricted stock units ("RSUs") and 201,702 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, 2016. In addition, in the first quarter of fiscal 2016 the Compensation Committee granted 48,163 RSUs with a two-year vesting term and no retirement-eligibility provisions under the SIP. 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 $4 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 are comprised of two separate and distinct awards with different vesting conditions.

The Compensation Committee granted 99,860 of the performance share awards based on a relative Total Shareholder Return ("TSR") metric over a performance period spanning November 9, 2015 to August 31, 2018. Award share payouts range from 0% 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 $2 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 101,842 performance share awards have a three-year performance period consisting of the Company’s fiscal 2016, 2017 and 2018. The performance targets are based on the Company's cash flow return on investment ("CFROI") over the three-year performance period, with award payouts ranging from 0% 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 $2 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, 2018.

In the second quarter of fiscal 2016, the Company granted deferred stock units ("DSU") to each of its non-employee directors under the Company's 1993 Stock Incentive Plan.
