Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | Note 8: Overview We have various share-based compensation programs, which provide for equity awards including non-qualified stock options, restricted stock shares, restricted stock units, performance awards and deferred compensation.

Grant-Date Fair Value We use the Black-Scholes option pricing model to calculate the grant-date fair value of an award.

We believe that this historical data is currently the best estimate of the expected term of a new option. We use a weighted-average expected life for all awards. Expected volatility – Volatility is calculated using our stock’s historical volatility for the same period of time as the expected life. We have no Risk-free interest rate – The rate is based on the U.S. Treasury yield curve in effect at the time of the grant for the same period of time as the expected life. Expected dividend yield – The calculation is based on the total expected annual dividend payout divided by the average stock price. Expense We use the straight-line attribution method to recognize share-based compensation expense for option awards, restricted stock shares and restricted stock units with graded and cliff vesting. Incentive stock options and performance awards are based on certain performance-based metrics and the expense is adjusted quarterly, based on our projections of the achievement of those metrics. The amount of share-based compensation expense recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. The expense is recognized over the requisite service period, which for us is the period between the grant-date and the earlier of the award’s stated vesting term or the date the employee is eligible for early vesting based on the terms of the plans. Total share-based compensation expense was $5,005 $3,191 three September 1, 2018 September 2, 2017, $15,439 $12,034 nine September 1, 2018 September 2, 2017, nine September 1, 2018, No. 2016 09. three nine September 2, 2017, $151 $1,504 As of September 1, 2018, $14,784 1.4 $11,749, 1.2 Stock Option Activity The stock option activity for the nine September 1, 2018 Average Options Exercise Price Outstanding at December 2, 2017 3,860,764 $ 42.28 Granted 810,306 53.07 Exercised (163,190 ) 30.86 Forfeited or cancelled (6,281 ) 44.00 Outstanding at September 1, 2018 4,501,599 $ 44.64 The fair value of options granted during the three September 1, 2018 September 2, 2017 $180 $46, three September 1, 2018 September 2, 2017 $2,066 $474, nine September 1, 2018 September 2, 2017 $9,217 $7,803, nine September 1, 2018 September 2, 2017 $3,876 $7,099, Proceeds received from option exercises during the three September 1, 2018 September 2, 2017 $2,841 $1,107, $5,228 $15,033 nine September 1, 2018 September 2, 2017 .
