Marathon Petroleum Corp current report, 15 December 2017

Business Context and Reporting Period

This Form 8-K, filed by Marathon Petroleum Corporation (MPC) on December 15, 2017, reports a material definitive agreement entered into by its subsidiary, MPLX LP ("MPLX"). The filing details a restructuring of the partnership interests between MPLX and its general partner, MPLX GP LLC ("MPLX GP"), which is a wholly-owned subsidiary of MPC.

Key Financial Metrics and Transaction Details

The filing does not report standard financial performance metrics such as revenue, profit, cash flow, or margins for the period. Instead, it outlines the following transaction specifics:

  • Transaction Type: Cancellation of MPLX GP's Incentive Distribution Rights (IDRs) and conversion of its 2% general partner interest into a non-economic general partner interest.
  • Consideration: MPLX GP will receive 275,000,000 MPLX common units in exchange for the cancelled rights and interest.
  • Ownership Impact: Prior to the transaction, MPC indirectly owned approximately 29% of MPLX common units (118,090,823 units) and all IDRs. Post-transaction, MPC's ownership will increase significantly due to the issuance of new units to MPLX GP.
  • Distribution Waiver: MPLX GP agreed to waive a portion of Q4 2017 distributions on the newly issued units to the extent they exceed the distributions MPLX GP would have received under the previous IDR and general partner interest structure.

Material Changes and Closing Conditions

The restructuring represents a fundamental change in the capital structure and economic alignment between MPLX and its general partner. The closing of the GP/IDR Restructuring is expected on February 1, 2018, subject to customary conditions and the simultaneous closing of a contribution of MPLX Refining Logistics LLC and MPLX Fuels Distribution LLC to MPLX.

Management Commentary and Governance

The terms of the agreement were approved by the conflicts committee and the board of directors of MPLX GP. The conflicts committee, comprised of independent directors, retained independent legal and financial advisors to evaluate and negotiate the restructuring.
