Leases [Abstract]

Leases

10. Leases

We have operating leases for our corporate offices and our manufacturing facility, and finance leases for equipment. Our leases have remaining lease terms of one month to three years. One of our primary operating leases includes options to extend the lease for one to three years and the other primary lease includes an option to annually prolong; those operating leases also include options to terminate the leases within one year. Future renewal options that are not likely to be executed as of the balance sheet date are excluded from right-of-use assets and related lease liabilities.

Our operating leases represent building leases for our Stockholm corporate offices and our Kungsbacka manufacturing facility. Our Stockholm corporate office lease has a remaining lease term of under one year and both of our leases are automatically renewed at a cost increase of 2% on an annual basis, unless we provide written notice nine months prior to the respective expiration dates.

We report operating lease right-of-use assets, as well as current and noncurrent operating lease obligations on our consolidated balance sheets for the right to use those buildings in our business. Our finance leases represent manufacturing equipment; we report the manufacturing equipment, as well as current and noncurrent finance lease obligations on our consolidated balance sheets.

Generally, interest rates are stated in our leases for equipment. When no interest rate is stated in a lease, however, we review the interest rates implicit in our recent finance leases to estimate our incremental borrowing rate. We determine the rate implicit in a lease by using the most recent finance lease rate, or other method we think most closely represents our incremental borrowing rate.
