Revenue information related to variable consideration constraint |  |  | The Company’s contracts generally do not give rise to variable consideration. However, during the three and nine months ended September 30, 2021, the Company recognized approximately $1,286,000 in revenue from a request for equitable adjustment (“REA”) under one of the Company’s Treatment Services contracts that resulted in cumulative catch-up adjustment in the transaction price that had been constrained in prior periods. |
