On June 30, 2020, the Company had stock options, stock awards and stock appreciation rights (SARs) outstanding under its 2011 Incentive Compensation Plan. SARs granted prior to 2015 are cash-settled, and SARs granted in 2015 and later are stock-settled. Stock options and SARs granted prior to 2017 generally cliff vested after two years. Starting in 2017, stock options and

SARs have a three-year graded vesting feature, with one-third of the awards vesting each year. The Company has elected the straight-line method of expense attribution for the stock options and SARs with the graded vesting feature.

Compensation expense recorded for all stock options, stock awards and SARs was as follows:

(In thousands)
Three Months Ended June 30				Six Months Ended June 30
2020		2019		2020		2019
$	2,989	$	2,176	$	4,191	$	4,772

The increase in stock-based compensation expense for the second quarter of 2020 compared to the second quarter of 2019 was primarily attributable to cash-settled SARs. The increase in cash-settled SARs compensation expense reflects a larger increase in the market value of Company stock during the second quarter of 2020 versus the increase in the market value of Company stock during the second quarter of 2019.
