MPLX LP Form 8-K Summary
Business Context and Reporting Period
This Current Report on Form 8-K, dated December 4, 2015, details the completion of a transformative merger and related financing activities by MPLX LP (MPLX). The primary event is the acquisition of MarkWest Energy Partners, L.P. (MarkWest), making MarkWest a wholly-owned subsidiary of MPLX. The report also covers the entry into a new loan agreement, the assumption of significant debt, and major changes to the executive leadership team.

- Debt Assumption: MPLX assumed approximately $4.1 billion in aggregate principal amount of senior notes issued by MarkWest, maturing between 2023 and 2025.
- New Financing: MPLX entered into a revolving loan agreement with MPC Investment LLC for up to $500 million, with a maturity date of December 4, 2020. Interest accrues at one-month LIBOR plus 150 basis points.
- Credit Facility: MPLX increased its revolving credit capacity by $1.0 billion to a total of $2.0 billion. Approximately $850 million was borrowed under this facility to repay MarkWest's bank revolving credit facility ($943 million outstanding), with the remainder paid in cash.

Material Changes Versus Prior Period
The most significant change is the consolidation of MarkWest's operations and balance sheet into MPLX. This includes the assumption of $4.1 billion in senior notes and the termination of MarkWest's independent credit facility. The capital structure has shifted to include new classes of limited partner interests (Class A and Class B) to accommodate the merger consideration. Additionally, the board of directors was expanded from ten to twelve members, and key executive roles were filled by former MarkWest leadership.
