Operating Lease |
Operating Lease | 4. Operating Lease Solitario accounts for its leases in accordance with ASC 842. Solitario leases one facility, its Wheat Ridge, Colorado administrative office (the “WR Lease”), that has a term of more than one year. Solitario has no other material operating lease costs. The WR Lease was extended to October 2023 during 2021 and Solitario recorded a net increase in right of use assets of $99,000 during 2021 upon the extension of the WR Lease. The WR Lease is classified as an operating lease and has a remaining term of 22 months at December 31, 2021. The right-of-use office lease asset for the WR Lease is classified as other assets and the related liability as a current office lease liability in the consolidated balance sheet. Lease expense is recognized on a straight-line basis over the lease term, with variable lease payments recognized in the period those payments are incurred. During 2021 and 2020, Solitario recognized $40,000 and $40,000, respectively, of non-cash lease expense for the WR Lease included in general and administrative expense. Cash lease payments of $39,000 and $42,000, respectively, were made on the WR Lease during 2021 and 2020 and this amount, less $4,000 and $4,000, respectively, of imputed interest during 2021 and 2020, reduced the related liability on the WR Lease. The discount rate within the WR Lease is not determinable and Solitario applied a discount rate of 5% based upon Solitario’s estimate of its cost of capital in recording the WR Lease. Solitario has $75,000 remaining cash payments as of December 31, 2021. The following is supplemental cash flow information related to our operating lease for 2021 and 2020:
