We believe these non-GAAP financial measures are useful to investors and analysts to analyze and compare our operating performance between periods by excluding items that do not reflect the core operating results of our business. Adjusted EBITDA and Segment Adjustment EBITDA should not be considered as a substitute for, or superior to segment income (loss) from operations, net income attributable to MPC, income before income taxes, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP. Adjusted EBITDA and Segment Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. Refining & Marketing margin is defined as sales revenue less cost of refinery inputs and purchased products, excluding any LCM inventory market adjustment. Fuel margin includes bankcard processing fees (as applicable). Merchandise margin is defined as the price paid by consumers less the cost of merchandise. We believe these non-GAAP financial measures are useful to investors and analysts to assess our ongoing financial performance because, when reconciled to the most comparable GAAP measures, they provide improved comparability between periods through the exclusion of certain items that we believe are not indicative of our core operating performance and that may obscure our underlying business results and trends. These measures should not be considered a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP, and our calculations thereof may not be comparable to similarly titled measures reported by other companies.

The results of these new businesses are reported in the Midstream segment prospectively from February 1, 2018, resulting in a net reduction to Refining & Marketing segment results and a net increase to Midstream segment results of $181 million, $232 million, $230 million and $231 million for first, second, third and fourth quarter 2018, respectively. No effect was given to prior periods as these entities were not considered businesses prior to February 1, 2018. b Full year 2015 includes a non-cash LCM inventory valuation charge of $370 million, which reduced Refining & Marketing and Speedway segment income by $345 million and $25 million, respectively. Full year 2016 includes a non-cash LCM benefit from reversing the LCM inventory valuation reserve of $370 million, which increased Refining & Marketing and Speedway segment income by $345 million and $25 million, respectively. c Fourth quarter 2018 R&M segment results include estimated costs of $759 million due to purchase accounting related inventory effects. d Non-cash benefit related to Capline restructuring. e Includes costs related to the Andeavor acquisition including financial advisor and legal fees, employee severance, and other expenses. f Reflects an impairment charge in 2015 for the cancellation of the Residual Oil Upgrader Expansion project, an MPLX goodwill impairment and equity method investment impairments in 2016 and MPC's share of gains from the sale of impaired assets owned by an equity affiliate in 2017 and 2018. g The fourth quarter 2018 includes $60 million related to the extinguishment of MPLX debt. h During 2017, we recorded a tax benefit of approximately $1.5 billion as a result of remeasuring certain deferred tax liabilities using the lower corporate tax rate enacted under the Tax Cuts and Jobs Act. First quarter 2019 includes $36 million of state deferred tax expense recorded as an out of period adjustment related to the Andeavor acquisition. 2
