Related Party Transactions [Abstract] |
Related Party Transactions Disclosure | Related-Party Transactions Affiliate Agreements We have various long-term, fee-based commercial agreements with our Sponsor, under which we provide terminal distribution, storage services, pipeline transportation, crude oil, natural gas and produced water gathering and processing, wholesale, and trucking services to Marathon, and Marathon commits to provide us with minimum monthly throughput volumes of crude oil, refined products and other products. If, in any calendar month, Marathon fails to meet its minimum volume commitments under these agreements, it will be required to pay us a shortfall payment. For the NGLs that we handle under keep-whole agreements, we transfer the commodity price risk exposure associated with these keep-whole agreements to Marathon pursuant to the Keep-Whole Commodity Fee Agreement, as amended (the “Keep-Whole Commodity Agreement”). Under the Keep-Whole Commodity Agreement, Marathon pays us a processing fee for NGLs related to the keep-whole agreements and delivers replacement dry gas to the producers on our behalf. We then pay Marathon a marketing fee in exchange for assuming the commodity price risk. The terms and pricing of this agreement are subject to revision each year. We have agreements for the provision of various general and administrative services by our Sponsor. Under our partnership agreement, we are required to reimburse our general partner and its affiliates for all costs and expenses they incur on our behalf for managing and controlling our business and operations. On January 30, 2019, TLGP and certain of its indirect subsidiaries entered into a secondment agreement between us and certain of our subsidiaries and Marathon Petroleum Logistics Services LLC (“MPLS”) and a secondment agreement between us and certain of our subsidiaries and Marathon Refining Logistics Services LLC (“MRLS”) (collectively, the “2019 Secondment Agreements”). Under the 2019 Secondment Agreements, MPLS and MRLS second certain employees to occupy positions within our business and organization and to conduct business on our behalf. While seconded by MPLS and MRLS to us, seconded employees remain on the payroll of MPLS or MRLS, as the case may be, and are eligible to participate in all MPLS or MRLS benefit plans that they would be eligible to participate in absent the secondment, but work for and are under our general direction, supervision and control. We reimburse MPLS or MRLS, as the case may be, for the payroll costs of the seconded employees, including base pay, bonuses and other incentive compensation plus a burden rate associated with benefits and other payroll costs for the portion of the employee’s time that is allocated to us. The 2019 Secondment Agreements are for a term of 10 years, but may be sooner terminated by us, MPLS or MRLS upon 60 days written notice. In connection with the entry into the 2019 Secondment Agreements, on January 30, 2019, our Sponsor entered into an agreement (the “Termination Agreement”) that terminated the Andeavor Secondment Agreement. The Termination Agreement had an effective date of January 1, 2019. Except to the extent specified under our amended omnibus agreement (the “Amended Omnibus Agreement”) or the 2019 Secondment Agreements, TLGP determines the amount of these expenses. Under the terms of the Amended Omnibus Agreement in effect as of June 30, 2019, we are required to pay our Sponsor an annual corporate services fee of $17 million for the provision of various centralized corporate services, including executive management, legal, accounting, treasury, human resources, health, safety and environmental, information technology, certain insurance coverage, administration and other corporate services. Pursuant to the applicable secondment agreements in effect, our Sponsor charged us $24 million and $4 million during the three months ended June 30, 2019 and 2018, respectively, and $47 million and $10 million during the six months ended June 30, 2019 and 2018, respectively, reflecting increased services provided in conjunction with the assets acquired in the 2018 Drop Down. Additionally, pursuant to the Amended Omnibus Agreement and 2019 Secondment Agreements, we reimburse our Sponsor for any direct costs incurred by our Sponsor in providing other operational services with respect to certain of our other assets and operations.
