Leases [Abstract] |
Lessee, Finance and Operating Lease | LEASES For further information regarding the adoption of ASC 842, including the method of adoption and practical expedients elected, see Note 2. Lessee We lease a wide variety of facilities and equipment including land and building space, office and field equipment, storage facilities and transportation equipment. Our remaining lease terms range from less than one year to 60 years. Most long-term leases include renewal options ranging from less than one year to 50 years and, in certain leases, also include purchase options. The lease term included in the measurement of right of use assets and lease liabilities includes options to extend or terminate our leases that we are reasonably certain to exercise. Options were included in the lease term primarily for retail store sites where we constructed property, plant and equipment on leased land that is expected to exist beyond the initial lease term. Under ASC 842, the components of lease cost were as follows:

Leases of Lessor Disclosure | Lessor MPLX has certain natural gas gathering, transportation and processing agreements in which it is considered to be the lessor under several implicit operating lease arrangements in accordance with GAAP. MPLX’s primary implicit lease operations relate to a natural gas gathering agreement in the Marcellus region for which it earns a fixed-fee for providing gathering services to a single producer using a dedicated gathering system. As the gathering system is expanded, the fixed-fee charged to the producer is adjusted to include the additional gathering assets in the lease. The primary term of the natural gas gathering arrangement expires in 2038 and will continue thereafter on a year-to-year basis until terminated by either party. Other implicit leases relate to a natural gas processing agreement in the Marcellus region and a natural gas processing agreement in the Southern Appalachia region for which MPLX earns minimum monthly fees for providing processing services to a single producer using a dedicated processing plant. The primary terms of these natural gas processing agreements expire during 2023 and 2033. MPLX did not elect to use the practical expedient to combine lease and non-lease components for lessor arrangements. The tables below represent the portion of the contract allocated to the lease component based on relative standalone selling price. Lessor agreements are currently deemed operating, as we elected the practical expedient to grandfather in historical ASC 840 lease classifications. MPLX may be required to re-classify existing operating leases to sales-type leases upon modification and related reassessment of the leases. Our revenue from implicit lease arrangements, excluding executory costs, totaled approximately $64 million and $195 million for the three and nine months ended September 30, 2019, respectively. The implicit lease arrangements related to the processing facilities contain contingent rental provisions whereby we receive additional fees if the producer customer exceeds the monthly minimum processed volumes. During the three and nine months ended September 30, 2019, MPLX did not receive any material contingent lease payments. The following is a schedule of minimum future rentals on the non‑cancellable operating leases as of September 30, 2019:

2019 | $ | 47 |
2020 | 186 |
2021 | 178 |
2022 | 176 |

2024 and thereafter | 1,269 |
