Compensation expense recorded for all stock options, performance shares, restricted stock units (RSUs) and stock appreciation rights (SARs) was as follows:


(In thousands)
Three Months Ended June 30,				Six Months Ended June 30,
2023		2022		2023		2022
$	1,158	$	3,998	$	2,157	$	6,955

The decrease in stock-based compensation expense for both the second quarter and first six months of 2023, compared to the same periods of 2022, was primarily attributable to Company management lowering its assessment of the achievement of

performance targets for certain grants and the non-recurrence of accelerated vesting of certain equity grants for the Company's former Chief Executive Officer, who retired on April 25, 2022.

Unrecognized compensation costs for stock options, performance shares, RSUs and SARs were as follows:


(In thousands)	June 30, 2023		December 31, 2022
Stock options	$	449	$	692
Performance shares and RSUs		5,596		6,144
SARs		5,909		5,211

The change in unrecognized compensation costs reflects the new 2023 grants of stock options, performance shares, RSUs and SARs and Company management lowering its assessment of the achievement of performance targets for certain grants.

The new 2023 grants were as follows:


	Shares
Stock options		2,777
Performance shares (at target) and RSUs		86,118
SARs		77,006

The unrecognized compensation costs at June 30, 2023, are expected to be recognized over weighted-average periods of 1.1 years for stock options, 1.9 years for performance shares and RSUs and 1.9 years for SARs.
