Note 9: 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 units, performance awards and deferred compensation. These equity awards fall under several plans and are described below.

Share-based Compensation Plans

We currently grant stock options and restricted stock units under equity compensation and deferred compensation plans.

Stock options are granted to officers and key employees at prices not less than the fair market value at the date of grant. Non-qualified stock options are generally exercisable beginning one year from the date of grant in cumulative yearly amounts of 33.3 percent. Incentive stock options are based on certain performance-based criteria and are generally exercisable at a stated date when the performance criteria is measured. Stock options generally have a contractual term of 10 years. Options exercised represent newly issued shares.

Restricted stock awards are nonvested stock-based awards that include grants of restricted stock units. Restricted stock awards are independent of option grants and are subject to forfeiture if employment terminates prior to the release of the restrictions. Such awards generally vest beginning one year from the date of grant or 33.3 percent per year for three years, depending on the grant. During the vesting period, ownership of the shares cannot be transferred.

Restricted stock units have dividend equivalent rights equal to the cash dividend paid on restricted stock shares. However, restricted stock units do not have voting rights of common stock and are not considered issued and outstanding upon grant. Restricted stock units become newly issued shares when vested. The dividend equivalent rights for restricted stock units are forfeitable.

We expense the cost, which is the grant date fair market value, of the restricted stock units ratably over the period during which the restrictions lapse. The grant date fair value is our closing stock price on the date of grant.

We are required to recognize compensation expense when an employee is eligible to retire. We consider employees eligible to retire at age 55 and after 10 years of service. Awards granted to retirement-eligible employees are forfeited if the retirement-eligible employees retire prior to 180 days after the grant. Accordingly, the related compensation expense is recognized during the 180 day period for awards granted to retirement-eligible employees or over the period from the grant date to the date retirement eligibility is achieved, if less than the stated vesting period.

2020 Master Incentive Plan

This plan allows for granting of awards to employees. The plan permits granting of (a) stock options; (b) stock appreciation rights; (c) restricted stock and restricted stock units; (d) performance awards; (e) dividend equivalents; (f) other awards based on our common stock, including shares for amounts employees deferred under the Key Employee Deferred Compensation Plan. There were 1,679,579 common shares available for grant as of November 28, 2020.

2018 Master Incentive Plan

Year 2016 Master Incentive Plan

This plan allows for granting of awards to employees. The plan permits granting of (a) stock options; (b) stock appreciation rights; (c) restricted stock awards; (d) performance awards; (e) dividend equivalents; and (f) other awards based on our common stock, including shares for amounts employees deferred under the Key Employee Deferred Compensation Plan.

2009 Directors’ Stock Incentive Plan

This plan permits granting of (a) shares for amounts non-employee directors defer under the Directors’ Deferred Compensation Plan and (b) discretionary grants of restricted stock, stock options, stock appreciation rights, performance awards and other stock awards.

Directors' Deferred Compensation Plan

This plan allows non-employee directors to defer all or a portion of their retainer and meeting fees in a number of investment choices, including units representing shares of our common stock. We provide a 10 percent match on deferred compensation invested in these units. These units are required to be paid out in our common stock.

Key Employee Deferred Compensation Plan

This plan allows key employees to defer a portion of their eligible compensation in a number of investment choices, including units representing shares of company common stock. We provide a 10 percent match on deferred compensation invested in these units.

Grant-Date Fair Valu

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 2020, 2019 and 2018 were calculated using the following assumptions:

		2020				2019					2018
Expected life (in years)				5.00					4.75					4.75
Weighted-average expected volatility				24.32	%				24.26	%				23.31	%
Expected volatility range		24.18%	-	30.99	%		23.88%	-	24.76	%		23.18%	-	23.58	%
Risk-free interest rate		0.21%	-	1.51	%		1.34%	-	2.55	%		2.38%	-	2.95	%
Weighted-average expected dividend				1.38	%				1.40	%				1.14	%
Expected dividend yield range		1.35%	-	2.53	%		1.25%	-	1.45	%		1.12%	-	1.24	%
Weighted-average fair value of grants	$			*9.63*		$			9.76		$			11.38

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 its future volatility will differ from the past.

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 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 $16,914, $24,003 and $17,113 for 2020, 2019 and 2018, respectively. All share-based compensation was recorded as SG&A expense.

As of November 28, 2020, $6,044 of unrecognized compensation costs related to unvested stock option awards is expected to be recognized over a weighted-average period of 0.7 years. Unrecognized compensation costs related to unvested restricted stock units was $5,304 which is expected to be recognized over a weighted-average period of 0.9 years.
