Leases

The Company has operating leases for various types of properties, consisting of manufacturing plants, engineering and research centers, distribution warehouses, offices and other facilities, and equipment used in operations. Some leases provide the Company with an option, exercisable at the Company's sole discretion, to terminate the lease or extend the lease term for one or more years. When measuring assets and liabilities arising from a lease that provides the Company with an option to extend the lease term, the Company takes into account payments to be made in the optional extension period when it is reasonably certain that the Company will exercise the option. Total lease cost (all of which related to operating leases) was $6.1 million for the three months ended March 31, 2019.
