Stock-Based Compensation	Sep. 30, 2021
Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation There have been no changes to our stock-based compensation plan as disclosed in our 2021 Annual Report on Form 10-K. However, as permitted under this plan, we made an initial grant of performance units in August 2021. These performance units have either a market condition or a performance condition and will vest 3 years after the grant date. Dividend equivalents earned during the vesting period will be paid at the time the awards vest. Our stock-settled stock appreciation rights (“SSSARs”) compensation expense was $1.0 million and $0.9 million for the three months ended September 30, 2021 and 2020, respectively. At September 30, 2021, there was $5.7 million of unrecognized compensation expense related to SSSARs that we will recognize over a weighted-average period of 2 years. Our restricted stock compensation expense was $1.1 million and $0.9 million for the three months ended September 30, 2021 and 2020, respectively. At September 30, 2021, there was $8.9 million of unrecognized compensation expense related to restricted stock that we will recognize over a weighted-average period of 2 years. Our performance units compensation expense was $0.2 million for the three months ended September 30, 2021. At September 30, 2021, there was $3.5 million of unrecognized compensation expense related to performance units that we will recognize over a weighted-average period of 3 years.
