Commitments | Note 10 ‑ Commitments Lease Agreements We lease facilities under non-cancellable operating leases. The leases expire at various dates through fiscal 2023 and frequently include renewal provisions for varying periods of time, provisions which require us to pay taxes, insurance and maintenance costs, and provisions for minimum rent increases. Minimum leases payments, including scheduled rent increases are recognized as rent expenses on a straight-line basis over the term of the lease. The rate implicit in each lease is not readily determinable, and we therefore use our incremental borrowing rate to determine the present value of the lease payments. The weighted average incremental borrowing rate used to determine the initial value of right-of-use (ROU) assets and lease liabilities during each of the years ended December 31, 2020 and 2019 was 6.75%. Right-of-use assets for operating leases are periodically reduced by impairment losses. We use the long-lived assets impairment guidance in ASC Subtopic 360-10, Property, Plant and Equipment – Overall, to determine whether a ROU asset is impaired, and if so, the amount of the impairment loss to recognize. As of December 31, 2020 and 2019, we have not recognized any impairment losses for our ROU assets. We monitor for events or changes in circumstances that require a reassessment of one of our leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset unless doing so would reduce the carrying amount of the ROU asset to an amount less than zero. In that case, the amount of the adjustment that would result in a negative ROU asset balance is recorded in profit or loss. In June 2020, the Company entered into a sublease agreement to lease 4,351 square feet of space located in Irvine, California for $5,439 per month with 3 percent annual increases.
