$	3,998	$	2,807	$	6,955	$	5,346

The increase in stock-based compensation expense for the second quarter of 2022 compared to the second quarter of 2021 was primarily attributable to the 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, stock awards and SARs were as follows:

(In thousands)	June 30, 2022		December 31, 2021
Stock options	$	1,327	$	2,229
Stock awards		9,924		4,971
SARs		7,606		4,828

The change in unrecognized compensation costs for stock options, stock awards and SARs primarily reflects the 2022 grants of:

	Shares
Stock options		34,444
Stock awards (at target)		64,311
SARs		188,835

The unrecognized compensation costs at June 30, 2022, are expected to be recognized over weighted-average periods of 1.4 years for stock options, 2.0 years for stock awards and 2.0 years for SARs.
