(the “2017 Plan”), which reserved up to 1,500,000 shares of common stock to be used for awards under the 2017 Plan.

On October 28, 2022 and 2021 and 2020, pursuant to the 2017 Plan, the Company awarded officers, directors and key employees restricted stock awards (RSAs), which is an award of common stock subject to time vesting. These RSA are restricted as to transference, sale and other disposition, and vest ratably over a three-year period. The RSAs may also vest in the event of a change of control. Upon termination, whether voluntary or involuntary, the RSAs that have not vested will be returned to the Company resulting in stock forfeitures. The fair market value of the stock on the date of grant is amortized and charged to selling, general and administrative expense over the stipulated time period over which the RSAs vest on a straight-line basis, net of estimated forfeitures.

The Company’s RSA activity and related information is presented below:


	Restricted Stock			Weighted- average Grant Date Fair Value
Unvested at December 31, 2021		465,035		$	25.48

Vested		(221,964	)		26.80
Forfeited		(34,457	)		24.23
Unvested at December 31, 2022		579,804		$	23.34

RSA compensation expense for the years ended December 31, 2022, 2021 and 2020 totaled $6.1 million, $8.0 million and $7.5 million, respectively. For 2022, 2021 and 2020, the income tax benefit recognized in net income for RSAs was $1.1 million, $1.3 million and $1.1 million, respectively. As of December 31, 2022, there was $13.6 million of total unrecognized compensation cost related to unvested RSAs, which is expected to be recognized over a weighted average period of 2.2 years.

On October 28, 2022, 2021 and 2020, pursuant to the 2017 Plan, the Company awarded performance unit awards (Performance Units) to officers and key employees. The Performance Units were valued on a per unit basis based on a Monte Carlo simulation at $29.38 for the 2022 grants, $29.88 for the 2021 grants, and $32.05 for the 2020 grants, approximately 126.2%, 126.9% and 134.3%, respectively, of the grant date share price. Under the terms of the Performance Units, participants may earn from 0% to 200% of their target award based upon the Company’s relative total share return (TSR) in comparison to the 15 component companies of the Philadelphia Oil Service Index and, starting with the 2020 grants, the S&P 500 Index. Starting with the 2022 grants, the Philadelphia Oil Service Index is being replaced by the VanEck Oil Services ETF Index.

The TSR is calculated over a three -year period from October 1, 2022 and 2021 and 2020 to September 30, 2025 and 2024, and 2023, respectively, and assumes reinvestment of dividends for companies within the index that pay dividends, which Dril-Quip does not.
