Leases | 7. LEASES We have lease agreements for equipment and facilities under long-term, non-cancelable leases. We determine if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether we obtain substantially all of the economic benefits from and have the ability to direct the use of the asset. Our lease agreements generally do not contain any material residual value guarantees or material restrictive covenants. Operating leases are included in operating lease right-of-use assets, current operating lease liabilities, and long-term operating lease liabilities in our condensed consolidated balance sheets. Operating lease right-of-use assets and corresponding operating lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term, plus payments made prior to lease commencement and any initial direct costs. Operating lease expense for operating lease assets is recognized on a straight-line basis over the lease term. As most of our leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We also have elected to apply a practical expedient for short-term leases whereby we do not recognize a lease liability or a right-of-use asset for leases with a term of 12 months or less. The Company recognizes short-term leases on a straight-line basis and does not record a related right-of-use asset or lease obligation for such contracts. Our leases have remaining lease terms that expire at various dates through 2029. Some of our lease terms may include options to extend or terminate the lease, and the Company includes those leases when it is reasonably certain we will exercise that option.
