Leases |
Leases | 4. Leases At the inception of an arrangement, the Company determines if an arrangement is, or contains, a lease based on facts and circumstances present in that arrangement. Lease classifications, recognition, and measurement are then determined at the lease commencement date. The Company’s operating lease right-of-use (“ROU”) assets and operating lease liabilities include primarily leases for office and warehouse spaces used to conduct our business. The Company’s operating leases also previously included the lease of a building with land where its Oak Ridge Environmental Waste Operations (“EWOC”) facility conducts its waste treatment operations. In July 2024, the Company completed the purchase of the EWOC property under the lease purchase option (see “Note 8 – Long Term Debt” for a discussion of the purchase of this property by the Company). Finance leases consist primarily of processing equipment and vehicles/trucks used by our facilities’ operations. The components of lease cost for the Company’s leases for the three and nine months ended September 30, 2024, and 2023 were as follows (in thousands): Schedule of Components of Lease Cost
