Share-Based Compensation

6 Months Ended

Jun. 30, 2022

Share-based Payment Arrangement [Abstract]

Our non-employee directors and key employees are granted share-based awards through our SICP. We record these share-based awards as compensation costs over the respective service period for which services are received in exchange for an award of equity or equity-based compensation. The compensation cost is based primarily on the fair value of the shares awarded, using the estimated fair value of each share on the date it was granted and the number of shares to be issued at the end of the service period.

The table below presents the amounts included in net income related to share-based compensation expense for the three and six months ended June 30, 2022 and 2021:

Non-employee Directors

Shares granted to non-employee directors are issued in advance of the directors’ service periods and are fully vested as of the grant date. We record a deferred expense equal to the fair value of the shares issued and amortize the expense equally over a service period of one year. In May 2022, after the most recent election of directors, each of our non-employee directors received an annual retainer of 652 shares of common stock under the SICP for service as a director through the 2023 Annual Meeting of Stockholders; accordingly, 6,520 shares, with a weighted average fair value of $130.36 per share, were issued and vested in 2022.

At June 30, 2022, there was approximately $0.7 million of unrecognized compensation expense related to shares granted to non-employee directors. This expense will be recognized over the remaining service period ending in May of 2023.

In July, 2022, we announced the appointment of two new non-employee directors to our current Board. These newly appointed directors will be granted share-based awards through the SICP that will be pro-rated in accordance with the beginning of their service period. The associated expense will be recognized in the same manner utilized for our current non-employee directors.

Key Employees

The table below presents the summary of the stock activity for awards to key employees for the six months ended June 30, 2022:


	Number of Shares	Weighted Average Fair Value
Outstanding—December 31, 2021	197,398	$	94.15
Granted	66,942	$	119.77
Vested	(60,850)	$	90.60
Expired	557	$	91.42

Outstanding—June 30, 2022	204,047	$	102.91

During the six months ended June 30, 2022, we granted awards of 66,942 shares of common stock to key employees under the SICP, including awards granted in February 2022 and to key employees appointed in officer positions. The shares granted are multi-year awards that will vest no later than the three-year service period ending December 31, 2024. All of these stock awards are earned based upon the successful achievement of long-term financial results, which are comprised of market-based and performance-based conditions or targets. The fair value of each performance-based condition or target is equal to the market price of our common stock on the grant date of each award. For the market-based conditions, we used the Monte Carlo valuation to estimate the fair value of each market-based award granted.

In March 2022, upon the election by certain of our executive officers, we withheld shares with a value at least equivalent to each such executive officer’s minimum statutory obligation for applicable income and other employment taxes related to shares that vested and were paid in February 2022 for the performance period ended December 31, 2021, paid the balance of such awarded shares to each such executive officer net cash remitted to the appropriate taxing authorities. We withheld 21,832 shares, based on the value of the shares on their award date. Total combined payments for the employees’ tax obligations to the taxing authorities were approximately $2.8 million.

At June 30, 2022, the aggregate intrinsic value of the SICP awards granted to key employees was approximately $26.4 million. At June 30, 2022, there was approximately $8.8 million of unrecognized compensation cost related to these awards, which will be recognized through 2024.
