3 Months Ended

Share-Based Payment Arrangement [Abstract]

Overview

We have stock option and stock incentive plans for employees and non-employee directors that provide for grants of restricted stock awards (“RSAs”), restricted stock units (“RSUs”), performance stock units (“PSUs”), and options to purchase shares of our common stock at exercise prices generally equal to the fair value of such stock at the dates of grant. We also maintain a shareholder-approved Employee Stock Purchase Plan (“ESPP”) for the benefit of our employees. The ESPP allows eligible employees to purchase common stock on a regular basis at the lower of 85% of the market price at the beginning or end of each offering period.

Equity Grants

During the three months ended March 31, 2024 the Compensation Committee of our Board of Directors (the “Committee”) authorized awards from approved stock incentive plans of RSUs and PSUs to certain employees and company officers, which, assuming that performance under the PSUs will be achieved at target levels, together totaled 700,000 shares and had an aggregate grant date fair value of $14.2 million.

During the three months ended March 31, 2023 the Committee authorized awards from approved stock incentive plans of RSUs and PSUs to certain employees and company officers, which, assuming that performance under the PSUs were to be achieved at target levels, together totaled 376,000 shares and had an aggregate grant date fair value of $5.0 million.

The Committee did not authorize any grants of stock options during the three months ended March 31, 2024 and 2023.

Employees purchased common stock totaling 51,000 and 56,000 shares in the three months ended March 31, 2024 and 2023, respectively, through the ESPP.

The following table summarizes total stock compensation expenses prior to the capitalization of amounts into Deferred preservation and Inventory costs (in thousands):


	Three Months Ended March 31,
		2024		2023
RSA, RSU, and PSU expense		$	2,985	$	2,641
Stock option and ESPP expense		687		872
Total stock compensation expense		$	3,672	$	3,513

Included in the total stock compensation expense, as applicable in each period, were expenses related to RSAs, RSUs, PSUs, and stock options issued in each respective year, as well as those issued in prior periods that continue to vest during the period, and compensation related to the ESPP. These amounts were recorded as stock compensation expense and were subject to our normal allocation of expenses to inventory costs and deferred preservation costs. We capitalized $194,000 and $172,000 for the three months ended March 31, 2024 and 2023, respectively, of the stock compensation expense into our inventory costs and deferred preservation costs.
