Leases [Abstract] |
Leases | Leases Lessee We lease office buildings, equipment and pipeline capacity (primarily to facilitate movements on our Longhorn pipeline and Little Rock pipeline extension) and have entered into storage contracts to conduct our business operations. We have also entered into land leases and easement and right-of-way contracts, several of which have cancellation penalties. Several of our agreements provide for negotiated renewal options, and management expects that we will generally renew our expiring leases. Leases are evaluated at inception or at any subsequent material modification and, depending on the lease terms, are classified as either capital or operating leases, as appropriate under ASC 840, Leases. We recognize rent expense on a straight-line basis over the life of the lease. Total rent expense was $30.2 million, $34.8 million and $42.1 million for the years ended December 31, 2016, 2017 and 2018, respectively. Future minimum annual rentals under non-cancellable operating leases and storage contracts with initial or remaining terms greater than one year as of December 31, 2018, were as follows (in millions):
2019 | $ | 33.8 |
2020 | 32.3 |
2021 | 30.2 |
2022 | 27.4 |
2023 | 26.7 |
Thereafter | 132.2 |
