CARES Act

On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which among other things includes an optional payment deferral of the employer's portion of the Social Security taxes that were otherwise due through December 31, 2020. The Company elected to defer payments of approximately $7.6 million with $3.8 million paid in December 2021 and the remaining $3.8 million due December 2022 reflected in accrued liabilities in the Company’s Consolidated Balance Sheets.
