Note 8. Leases

We have entered into a number of facility and equipment leases which qualify as operating leases under GAAP. We also have a limited number of equipment leases that qualify as finance leases. We determine if contracts with vendors represent a lease or have a lease component under GAAP at contract inception. Our leases have remaining terms ranging from less than one year to six years. Some of our leases include options to extend or terminate the lease prior to the end of the agreed upon lease term. For purposes of calculating lease liabilities, lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise such options.

Operating lease right of use assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the lease commencement date. As our leases generally do not provide an implicit rate, we use an estimated incremental borrowing rate in determining the present value of future payments. The incremental borrowing rate represents an estimate of the interest rate we would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of a lease within a particular location and currency environment.

Lease costs for minimum lease payments is recognized on a straight-line basis over the lease term. For operating leases, costs are included within Cost of revenues, Research and development, Sales and marketing, and General and administrative lines on the Condensed Consolidated Statements of Operations. For financing leases, amortization of the finance right of use assets is included within Research and development, Sales and marketing, and General and administrative lines on the Condensed Consolidated Statements of Operations, and interest expense is included within Interest expense.

For operating leases, the related cash payments are included in the operating cash flows on the Condensed Consolidated Statements of Cash Flows. For the three months ended December 31, 2022 and 2021, cash payments related to operating leases were $1.8 million and $1.6 million, respectively. For financing leases, the related cash payments for the principal portion of the lease liability are included in the financing cash flows on the Condensed Consolidated Statement of Cash Flows and the related cash payments for the interest portion of the lease liability are included within the operating section of the Condensed Consolidated Statement of Cash Flows. For the three months ended December 31, 2022 and 2021, cash payments related to financing leases were $0.1 million and $0.2 million, respectively, of which an immaterial amount related to the interest portion of the lease liability. For the three months ended December 31, 2022 and 2021, right of use assets obtained in exchange for lease obligations were $2.5 million and $3.1 million, respectively.
