Commitments:

Leases  

The Company determines whether an arrangement is a lease at inception. The Company and its subsidiaries have operating leases for certain manufacturing, laboratory, office facilities and certain equipment. The leases have remaining lease terms of less than one year to less than five years. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. As of June 30, 2021 and December 31, 2020, the Company has no assets recorded under finance leases.

Lease expense for these leases is recognized on a straight-line basis over the lease term. For the three and six months ended June 30, total lease costs are comprised of the following:

Contingencies:

Legal

We are subject to legal proceedings, claims and liabilities which arise in the ordinary course of business. When applicable, we accrue for losses associated with legal claims when such losses are probable and can be reasonably estimated. These accruals are adjusted as additional information becomes available or circumstances change. Legal fees are charged to expense as they are incurred.

The Company has been named as a party in the December 19, 2019 United States Environmental Protection Agency (“EPA”) Demand Letter regarding the Malta Rocket Fuel Area Superfund Site (“Site”) located in Malta and Stillwater, New York in connection with an alleged release of hazardous materials into the environment. The EPA is seeking reimbursement of response costs from all named parties in the amount of approximately $358 thousand plus interest in connection with the investigation and disposal activities associated with the various drum caches discovered at the Site, issuance of the Explanation of Significant Differences (“ESD”) of the Site, and implementation of the work contemplated by the ESD. The Company considers the likelihood of a material adverse outcome to be remote and does not currently anticipate that any expense or liability it may incur as a result of these matters in the future will be material to the Company's financial condition.
