Note 7: Accounting for Share-Based Compensation

Overview 

We have various share-based compensation programs which provide for equity awards including non-qualified 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 30, 2019.

Grant-Date Fair Value 

We use the Black-Scholes option pricing model to calculate the grant-date fair value of stock option awards. The fair value of options granted during the six months ended May 30, 2020 and June 1, 2019 was calculated using the following weighted average assumptions:

	Three Months Ended								Six Months Ended
	May 30, 2020				June 1, 2019				May 30, 2020				June 1, 2019
Expected life (in years)			5.00				4.75				5.00				4.75
Weighted-average expected volatility			24.20%				24.70%				24.29%				24.26%
Expected volatility		24.18%	-	24.26%		24.39%	-	24.76%		24.18%	-	24.30%		24.25%	-	24.76%
Risk-free interest rate			0.38%			2.17%	-	2.31%		0.36%	-	1.51%		2.17%	-	2.55%
Weighted-average expected dividend yield			2.34%				1.42%				1.38%				1.40%
Expected dividend yield range		1.84%	-	2.53%		1.26%	-	1.45%		1.35%	-	2.53%		1.26%	-	1.45%
Weighted-average fair value of grants			$4.48				$9.49				$9.63				$9.80

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 stock’s 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

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 $4,533 and $8,266 for the three months ended May 30, 2020 and June 1, 2019, respectively and $9,236 and $14,172 for the six months ended May 30, 2020 and June 1, 2019, respectively. All share-based compensation expense was recorded as selling, general and administrative (SG&A) expense.

As of May 30, 2020, there was $9,975 of unrecognized compensation costs related to unvested stock option awards, 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 $9,432, which is expected to be recognized over a weighted-average period of 1.2 years.
