What is the primary purpose of this 8-K/A filing?

This 8-K/A filing serves as an amendment to provide the necessary financial statements and pro forma information related to Marathon Petroleum Corp's (MPC) acquisition of MarkWest Energy Partners, L.P. (MWE). It incorporates by reference previously filed financial data for MWE and presents pro forma statements showing the combined entity's financial position.

Where can I find the detailed financial statements for the acquired business (MWE)?

The audited consolidated financial statements of MWE for the year ended December 31, 2014, are incorporated by reference from MWE's Annual Report on Form 10-K filed on February 25, 2015. The unaudited condensed consolidated financial statements for the periods ending September 30, 2015 and 2014 are incorporated by reference from MWE's Quarterly Report on Form 10-Q filed on November 4, 2015.

What is the significance of the 'pro forma' financial information mentioned in the filing?

The unaudited pro forma consolidated financial statements present how MPC and MWE's financial results might have looked if the acquisition had occurred at an earlier point in time. This provides investors with a clearer view of the combined entity's financial performance and position, as if they were already merged for the presented periods (as of September 30, 2015, for the nine months ended September 30, 2015, and for the year ended December 31, 2014).

Are there any new financial statements directly included in this filing?

No, this 8-K/A filing does not directly include new financial statements. Instead, it incorporates by reference financial statements and pro forma information from other previously filed documents by MPC and MWE.
