In accordance with ASC 718, Compensation-Stock Compensation, the Company measures the cost of employee services rendered in exchange for share-based compensation based upon the grant date fair market value. The cost is recognized over the requisite service period, which is generally the vesting period unless service or performance conditions require otherwise. The Company recognizes the impact of forfeitures as they occur.

Equity compensation expense is included in operating expenses and in selling, general and administrative expenses in the accompanying unaudited condensed consolidated statements of operations as follows:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2022		2021		2022		2021
	(In thousands)
Equity compensation expense included in operating expenses	$	961	$	3,297	$	3,615	$	5,799
Equity compensation expense included in selling, general and administrative expenses		3,483		9,752		10,360		17,357
Total equity compensation expense	$	4,444	$	13,049	$	13,975	$	23,156

During the three and nine months ended September 30, 2021, cumulative equity compensation expense was recorded related to certain performance vesting restricted awards which were previously not considered likely of vesting.

The Company has reserved 15.0 million shares of common stock for issuance under its Omnibus Incentive Plan (the “Omnibus Incentive Plan”), of which approximately 7.3 million shares are available for future issuance as of September 30, 2022.

During the nine months ended September 30, 2022, the Company granted approximately 115,000 performance-vesting restricted units (the “Bonus Performance Restricted Units”) in accordance with its annual bonus plan for 2022 (the “2022 Bonus Plan”). The 2022 Bonus Plan provides for bonus awards payable 50% in cash and 50% in performance-vesting restricted units (the “Bonus Performance Restricted Units”) and is based upon the Company’s achievement of specified performance goals, including the achievement of certain cost targets, as defined by the 2022 Bonus Plan, with respect to the year ended December 31, 2022 (“Fiscal 2022”). The total number of units eligible to vest into shares of stock is based on the level of achievement of the targets for Fiscal 2022 which ranges from 0% (if below threshold performance), to 100% (if at target performance) with opportunities to earn above 100% when achievement is above the target performance for certain metrics.

The Company also had an annual bonus plan for the fiscal year ended December 31, 2021 (“Fiscal 2021”), under which certain employees were eligible to vest in Bonus Performance Restricted Units based upon the Company’s achievement of certain performance goals with respect to Fiscal 2021. Based on the Company’s actual Fiscal 2021 results, a portion of these Bonus Performance Restricted Units vested and were converted into approximately 120,000 shares in the nine months ended September 30, 2022 and the remaining unvested units forfeited in accordance with their terms.

During the nine months ended September 30, 2022, the Company granted long-term incentive plan awards for 2022 (the “2022 Long-Term Incentive Grant”) which were comprised of approximately 50,000 nonqualified stock options (the “Long-Term Incentive Options”) and approximately 160,000 performance-vesting restricted units (the “Long-Term Incentive Performance Restricted Units”) (collectively, the “Long-Term Incentive Awards”).

The Long-Term Incentive Options vest over three years, with one-third vesting on each anniversary of the date of grant, subject to continued service through the applicable vesting date. Equity compensation expense for these options is recognized for each tranche over the vesting period using the straight-line method. Upon stock option exercises, authorized but unissued shares are issued by the Company.

The Long-Term Incentive Performance Restricted Units are eligible to vest during the three-year performance period beginning on January 1, 2022 and ending on December 31, 2024 (or, extended through December 31, 2025, as applicable) (the “Performance Period”) based upon the Company’s achievement of specified performance goals during the Performance Period. The total number of Long-Term Incentive Performance Restricted Units eligible to vest will be based on the level of achievement of the performance goals and ranges from 0% (if below threshold performance) up to 150% (for maximum performance). Upon achievement of at least the threshold performance goals, 50% of the award for a given level of performance will vest, with the remaining 50% subject to a one-year performance test period. Performance for the test period must meet or exceed the prior year’s performance before up to the remaining 50% of the units can be earned.

During the nine months ended September 30, 2022, a portion of the previously granted long-term incentive performance restricted units under the 2019 Long-Term Incentive Plan vested based on the Company’s actual Fiscal 2021 results. The remainder of the 2019 Long-Term Incentive Plan awards are eligible to vest in 2023 and/or 2024.

The Company recognizes equity compensation expense for its performance-vesting restricted awards ratably over the related performance period if the performance condition is probable of being achieved. If the probability of vesting changes for performance-vesting restricted awards in a subsequent period, all equity compensation expense related to those awards, that would have been recorded, if any, over the requisite service period had the new percentage been applied from inception, will be recorded as a cumulative catch-up or reduction at such subsequent date.
