Related Party Transactions [Abstract] |
Related-Party Transactions | RELATED-PARTY TRANSACTIONS AFFILIATE AGREEMENTS The Partnership has various long-term, fee-based commercial agreements with Tesoro, under which we provide pipeline transportation, trucking, terminal distribution and storage services to Tesoro, and Tesoro typically commits to fixed fees or to provide us with minimum monthly throughput volumes of crude oil and refined products. For the natural gas liquids (”NGLs”) that we handle under “keep-whole” agreements, the Partnership has a fee-based processing agreement with Tesoro which minimizes the impact of commodity price movements during the annual period subsequent to renegotiation of terms and pricing each year. In addition, we have agreements for the provision of various general and administrative services by Tesoro. Under our partnership agreement, we are required to reimburse TLGP and its affiliates for all costs and expenses that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our amended omnibus agreement (the “Amended Omnibus Agreement”) or our secondment agreement (the “Secondment Agreement”), TLGP determines the amount of these expenses. Under the terms of the Amended Omnibus Agreement, we are required to pay Tesoro an annual corporate services fee, currently $9 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. Under the terms of our Secondment Agreement, we pay Tesoro a net annual service fee, currently $2 million, for services performed by field-level employees at the majority of our facilities. Additionally, we reimburse Tesoro for any direct costs actually incurred by Tesoro in providing other operational services with respect to certain of our other assets and operations. Tesoro may also provide us other services for which we will be charged fees as determined by TLGP.
