Noncontrolling Interest [Abstract]

NONCONTROLLING INTERESTS

19. NONCONTROLLING INTERESTS

We have noncontrolling interests in the following consolidated subsidiaries: OLP, NDPC, and MEP. The noncontrolling interest in the OLP arises from the joint funding arrangements with our General Partner and its affiliate to finance certain expansion projects on our Lakehead system, which we refer to as the Eastern Access and Mainline Expansion Projects. Noncontrolling interest in NDPC arose from our agreement with Williston, an affiliate of MPC, to, among other things, fund 37.5% of the Sandpiper Project. Noncontrolling interest in MEP arises from its public unitholders’ ownership interests in MEP. On January 26, 2017 MEP entered into a definitive merger agreement with our General Partner, whereby our General Partner will acquire, for cash, all of the outstanding publicly held Class A common units of MEP. As a result, after the closing date, noncontrolling interest in MEP will be held by our General Partner.
