11. 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 five 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.
