Stock-Based Compensation

(13) Stock-Based Compensation

As of December 31, 2022, the Company maintains one stock incentive plan, the Third Amended and Restated 2004 Stock Incentive Plan (the 2004 Stock Incentive Plan). At December 31, 2022, 955,686 shares of Class A common stock were authorized for future grants of new equity awards under this plan. The Company currently grants shares of deferred stock awards to key employees and stock awards to non-employee members of the Company’s Board of Directors under the 2004 Stock Incentive Plan. The Company also previously granted shares of restricted stock to key employees. Stock awards to non-employee members of the Company’s Board of Directors vest immediately. Employees’ restricted stock awards and deferred stock awards typically vest over a three-year period at the rate of one-third per year. The restricted stock awards are outstanding upon grant whereas the deferred stock awards are outstanding upon vesting. The restricted stock awards and deferred stock awards are amortized to expense on a straight-line basis over the vesting period. 

The Company also grants performance stock units to key employees under the 2004 Stock Incentive Plan. Performance stock units cliff vest at the end of a performance period set by the Compensation Committee of the Board of Directors at the time of grant, which is currently three years. Upon vesting, the number of shares of the Company’s Class A common stock awarded to each performance stock unit recipient will be determined based on the Company’s performance relative to certain performance goals set at the time the performance stock units were granted. The recipient of a performance stock unit award may earn from zero shares to twice the number of target shares awarded to such recipient. The performance stock units are amortized to expense over the vesting period, and based on the Company’s performance relative to the performance goals, may be adjusted. Changes to the estimated shares expected to vest will result in adjustments to the related share-based compensation expense that will be recorded in the period of change. If the performance goals are not met, no awards are earned and previously recognized compensation expense is reversed. The Company granted performance stock units in 2022, 2021 and 2020. The performance goals for the performance stock units are based on the compound annual growth rate of the Company’s revenue over the three-year performance period and the Company’s return on invested capital (ROIC) for the third year of the performance period.

Beginning in 2019, the Company included “retirement vesting” provisions in the agreements for its deferred stock awards and performance stock units. These provisions provide that an employee who retires from the Company after attaining age 55 and 10 years of service and who meets certain other requirements, including non-competition and non-solicitation requirements, would be allowed to continue to vest in his or her deferred stock awards for the duration of the vesting periods and would be entitled to receive a pro rata portion of his or her performance stock units based on the period of service elapsed during the performance period. Beginning in 2022, a provision was added that requires the employee remain employed through the last working day of the grant year in addition to the other provisions.

In 2015, the Company stopped granting stock options as part of its annual equity awards to employees. Previously under the 2004 Stock Incentive Plan, key employees were granted nonqualified stock options to purchase the Company’s Class A common stock. Minimal options remain outstanding, all of which are vested and expire ten years from the date of grant. Options granted under the plan may have exercise prices of not less than 100% of the fair market value of the Class A common stock on the date of grant. The Company’s practice was to grant all options at fair market value on the grant date. Upon exercise of options, the Company issues shares of Class A common stock.

The Company also has a Management Stock Purchase Plan that allows for the granting of restricted stock units (RSUs) to key employees. On an annual basis, key employees may elect to receive a portion of their annual incentive compensation in RSUs instead of cash. Participating employees may use up to 50% of their annual incentive bonus to purchase RSUs for a purchase price equal to 80% of the fair market value of the Company’s Class A common stock as of the date of grant. RSUs vest either annually over a three-year period from the grant date or upon the third anniversary of the grant date. Receipt of the shares underlying RSUs is deferred for a minimum of three years, or such greater number of years as is chosen by the employee, from the date of grant. An aggregate of 2,000,000 shares of Class A common stock may be issued under the Management Stock Purchase Plan. At December 31, 2022, 705,188 shares of Class A common stock were authorized for future grants under the Company’s Management Stock Purchase Plan.

The following table summarizes information about RSUs outstanding at December 31, 2022:

	RSUs Outstanding			RSUs Vested
		Weighted Average			Weighted Average
	Number	Purchase		Number	Purchase

	77	$	94.78	24	$	77.69

The fair value of each share issued under the Management Stock Purchase Plan is estimated on the date of grant, using the Black-Scholes-Merton Model, based on the following weighted average assumptions:

	2022		2021
Expected life (years)	3.0		3.0
Expected stock price volatility	33.7	%	32.7	%
Expected dividend yield	0.80	%	0.75	%
Risk-free interest rate	2.0	%	0.3	%

The risk-free interest rate is based upon the U.S. Treasury yield curve at the time of grant for the respective expected life of the RSUs. The expected life (estimated period of time outstanding) of RSUs and volatility were calculated using historical data. The expected dividend yield of stock is the Company’s best estimate of the expected future dividend yield.

The above assumptions were used to determine the weighted average grant-date fair value of RSUs granted of $47.26, $37.49 and $22.36 during 2022, 2021 and 2020, respectively.

At December 31, 2022, the Company had total unrecognized compensation costs related to unvested stock-based compensation arrangements of approximately $18.7 million and a total weighted average remaining term of 1.38 years. For 2022, 2021 and 2020, the Company recognized compensation costs related to stock-based programs of $18.4 million, $22.9 million, and $12.7 million, respectively. For 2022, 2021 and 2020, stock compensation expense of $1.3 million, $1.4 million and $0.9 million, respectively, was recorded in cost of goods sold and $17.1 million, $21.5 million and $11.8 million, respectively, was recorded in selling, general and administrative expenses. For 2022, 2021 and 2020, the Company recorded $2.8 million, $3.7 million and $2.1 million, respectively, of tax benefit for its other stock-based plans. For 2022, 2021 and 2020, the recognition of total stock-based compensation expense impacted both basic and diluted net income per common share by $0.43, $0.53 and $0.30, respectively.
