(a) | We revised our operating segment presentation in the first quarter of 2017 in connection with the contribution of certain terminal, pipeline and storage assets to MPLX. The operating results for these assets, which were previously included in the Refining & Marketing segment, are now included in the Midstream segment. Comparable prior period information has been recast to reflect our revised presentation. The results for the pipeline and storage assets were recast effective January 1, 2015 and the results for the terminal assets were recast effective April 1, 2016. Prior to these dates these assets were not considered businesses and therefore there are no financial results from which to recast segment results.
(b) | Corporate overhead expenses attributable to MPLX are included in the Midstream segment. Corporate overhead expenses are not allocated to the Refining & Marketing and Speedway segments.
(c) | See Note 14 to the unaudited consolidated financial statements for further information on the goodwill impairment recognized in the first three months ended March 31, 2016.
(d) | Capital expenditures include changes in capital accruals, acquisitions and investments in affiliates.
(e) | The three months ended March 31, 2017 includes $220 million for the acquisition of the Ozark pipeline and an investment of $500 million in MarEn Bakken related to the Bakken Pipeline system.
(f) | Includes capitalized interest of $12 million and $17 million for the three months ended March 31, 2017 and 2016, respectively.
