Leases

6 Months Ended

Jun. 30, 2019

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 11 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.

Our total operating lease expenses for the three and six months ended June 30, 2019 were $10 million and $19 million, respectively, and were $8 million and $15 million for the three and six months ended June 30, 2018, respectively. The total amount of variable and short term lease payments were immaterial for all periods presented.
