We lease certain of our manufacturing facilities under operating leases. We also lease production equipment, vehicles, computer equipment, storage units and office equipment under operating leases. Our leases have remaining lease terms of 1 year to 9 years, some of which may include options to extend the leases for up to 5 years, and some of which may include options to terminate the leases within 1 year. All of our leases are operating leases. We did not recognize right-of-use assets or lease liabilities for certain short-term leases that are month-to-month leases. The lease expense relating to these leases is not significant.
