On January 1, 2019, we adopted ASC 842 using the optional transition method provided by ASU 2018-11. Our operating leases primarily consist of real estate leases such as offices, warehouses, and research and development facilities. Our leases have remaining lease terms ranging from 1 year to 10 years, some of which include options to extend the leases for up to 5 years or to terminate the leases within 1 year. Our finance leases are immaterial.
