The Company's primary operating lease is for space at a data center which was renewed in April 2022 and expires in 2025. In April 2023, the Company finalized exercising an option to decrease the space at the data center under the operating lease. As a result, the Company remeasured its lease liability and adjusted its ROU assets by $565, respectively, during 2023.

The Company evaluates new contractual arrangements at inception to determine if the contract is or contains a lease. For any contracts that are or contain a lease, the Company determines the appropriate classification of each identified lease as operating or finance. For all identified leases, the Company records the related lease liabilities and ROU assets based on the future minimum lease payments over the lease term, which only includes options to renew the lease if it is reasonably certain that the Company will exercise that option. For leases with original terms of twelve months or less, the Company recognizes the lease expense as incurred and does not recognize lease liabilities and ROU assets.

Lease liabilities are measured based on the future minimum lease payments discounted over the lease term. The Company uses the discount rate implicit in the lease whenever that rate is readily determinable. For leases where no such rate is determinable, the Company uses its incremental borrowing rate, or the rate of interest that Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term and in a similar economic environment. As of December 31, 2023, the weighted-average rate used in discounting the lease liabilities for ROU operating leases was 6.0%. Current and non-current operating lease liabilities are presented on the condensed consolidated balance sheet.

Operating lease costs, consisting primarily of rental expense, were approximately $1,842 and $3,654 for the years ended December 31, 2023 and 2022, respectively. Variable rent expense was not material for the years ended December 31, 2023 or 2022.
