Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | Note 3: Accounting for Share-Based Compensation Overview We have various share-based compensation programs, which provide for equity awards including stock options, incentive stock options, restricted stock shares, restricted stock units, performance awards and deferred compensation. These equity awards fall under several plans and are described in detail in our Annual Report on Form 10-K for the year ended November 28, 2015. Grant-Date Fair Value We use the Black-Scholes option pricing model to calculate the grant-date fair value of an award. The fair value of options granted during the quarter ended February 27, 2016 and February 28, 2015 were calculated using the following weighted average assumptions: Quarter Ended February 27, 2016 February 28, 2015 Expected life (in years) 4.75 4.61 Weighted-average expected volatility 29.03% 30.91% Expected volatility 29.03% - 29.23 25.50% - 31.67% Risk-free interest rate 1.44% 1.26% Expected dividend yield 1.56% 1.17% Weighted-average fair value of grants $ 7.64 $ 10.21 Expected life – We use historical employee exercise and option expiration data to estimate the expected life assumption for the Black-Scholes grant-date valuation. 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 historical volatility for the same period of time as the expected life. We have no reason to believe that our future volatility will differ materially from historical volatility. 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 Recognition 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. Total share-based compensation expense of $4,267 and $4,261 was included in our Condensed Consolidated Statements of Income for the quarter ended February 27, 2016 and February 28, 2015, respectively. All share-based compensation expense was recorded as selling, general and administrative expense. For the quarter ended February 27, 2016, there was $341 charged against the APIC Pool for tax deficiencies. For the quarter ended February 28, 2015, there was $397 of excess tax benefit recognized. As of February 27, 2016, there was $10,748 of unrecognized compensation costs related to unvested stock option awards, which is expected to be recognized over a weighted-average period of 1.6 years. Unrecognized compensation costs related to unvested restricted stock shares was $436 which is expected to be recognized over a weighted-average period of 0.9 years. Unrecognized compensation costs related to unvested restricted stock units was $11,631 which is expected to be recognized over a weighted-average period of 1.7 years.
