The decrease in stock-based compensation expense for the three and nine months ended September 30, 2021 as compared to the same periods of the prior year is primarily due to lower expense in 2021 associated with restricted stock awards issued in 2020 and 2021 with a three to six month vesting period in lieu of cash payments for certain compensation owed to employees, as part of our cash savings initiative in connection with the global COVID-19 pandemic.
