We enter into operating leases for certain manufacturing plants, warehouses, equipment and automobiles. Our leases have remaining lease terms of 1 to 13 years. Several leases include options for us to purchase leased items at fair value or renew for up to 5 years, or multiple 5-year renewal periods. Some of our leases include early termination options. We consider all of these options in determining the lease term used to establish our right-of-use (“ROU”) assets and lease liabilities when it is reasonably certain that we will exercise that option. Our lease agreements do not contain any residual value guarantees or material restrictive covenants.

We have lease agreements with lease and non-lease components, which are accounted for separately. Short-term leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense for these leases on a straight-line basis over the lease term. Short-term lease expense was not material for the three and six months ended June 30, 2020 and 2019.

As most of our leases do not provide an implicit rate, we use our incremental borrowing rate (“IBR”) based on information that is available at the lease commencement date to compute the present value of lease payments. Relevant information used in determining the IBR includes the transactional currency of the lease and the lease term. We used the IBR on January 1, 2019 for operating leases that commenced prior to that date. As of June 30, 2020, we did not have any finance leases or any operating leases that had not yet commenced.

The following tables present our operating lease cost and supplemental cash flow information related to our operating leases:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2020		2019		2020		2019
Operating lease cost	$	1.8	$	1.7	$	3.5	$	3.3

	Six Months Ended
	June 30,
	2020		2019 ⁽¹⁾
ROU assets obtained in exchange for lease obligations	$	1.1	$	35.6

The amount of cash paid for amounts included in the measurement of lease liabilities was not materially different from our operating lease cost for the six months ended June 30, 2020 and 2019.

The following table presents supplemental balance sheet information related to our operating leases:
