Leases

3 Months Ended

Mar. 31, 2019

We lease certain pipeline and transportation equipment. 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.

Our leases do not have any outstanding renewal options. Certain leases also include options to purchase the leased equipment.

Certain of our lease agreements include rates based on equipment usage and others include rate inflationary indices based increases. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.
