[4] The Company entered into a Facility Closure Trust Agreement for the benefit of the Nevada Division of Conservation and Natural Resources (NDEP). The funds that were deposited in the Trust were to be available when and if needed for closure and/or post-closure care of the facility related to potential decontamination and hazardous material cleanup. Due to the change in the primary use of the Company's McCarran, Nevada facility, the Written Determination issued to the Company requiring the Facility Closure Trust deposit was terminated by the NDEP on December 9, 2020. As a result of this termination, the Trust account was closed and the Trustee reimbursed the Company the entire balance of the Trust account.
