MPLX LP is a diversified, large-cap master limited partnership formed in 2012 by Marathon Petroleum Corporation (MPC). On July 30, 2019, we completed the merger with Andeavor Logistics LP (ANDX). Financial information has been retrospectively adjusted for the acquisitions of Hardin Street Marine LLC, Hardin Street Transportation LLC, Woodhaven Cavern LLC and MPLX Terminals LLC as these transactions were considered transfers between entities under common control. Financial information has been retrospectively adjusted for the acquisitions of ANDX as noted on the following pages. Transfers of businesses between entities under common control require prior periods to be retrospectively adjusted to furnish comparative information.

In addition to our financial information presented in accordance with U.S. generally accepted accounting principles (GAAP), management utilizes additional non-GAAP measures to facilitate comparisons of past performance and future periods. This press release and supporting schedules include the non-GAAP measures adjusted EBITDA; consolidated debt to last twelve months pro forma adjusted EBITDA, which we refer to as our leverage ratio; distributable cash flow (DCF); distribution coverage ratio; and free cash flow (FCF) and excess/deficit cash flow. The amount of adjusted EBITDA and DCF generated is considered by the board of directors of our general partner in approving the Partnership's cash distribution. Adjusted EBITDA and DCF should not be considered separately from or as a substitute for net income, income from operations, or cash flow as reflected in our financial statements. The GAAP measures most directly comparable to adjusted EBITDA and DCF are net income and net cash provided by operating activities. We define Adjusted EBITDA as net income adjusted for (i) depreciation and amortization; (ii) provision/benefit for income taxes; (iii) amortization of deferred financing costs; (iv) gain/loss on extinguishment of debt; (v) non-cash equity-based compensation; (vi) impairment expense; (vii) net interest and other financial costs; (viii) income/loss from equity method investments; (ix) distributions and adjustments related to equity method investments; (x) unrealized derivative gains/losses; (xi) acquisition costs; (xii) noncontrolling interest and (xiii) other adjustments as deemed necessary. In general, we define DCF as adjusted EBITDA adjusted for (i) deferred revenue impacts; (ii) net interest and other financial costs; (iii) maintenance capital expenditures; (iv) equity method investment capital expenditures paid out; and (v) other adjustments as deemed necessary. Adjusted EBITDA is a financial performance measure used by management, industry analysts, investors, lenders, and rating agencies to assess the financial performance and operating results of our ongoing business operations. Additionally, we believe adjusted EBITDA provides useful information to investors for trending, analyzing and benchmarking our operating results from period to period as compared to other companies that may have different financing and capital structures. DCF is a financial performance measure used by management as a key component in the determination of cash distributions paid to unitholders. We believe DCF is an important financial measure for unitholders as an indicator of cash return on investment and to evaluate whether the partnership is generating sufficient cash flow to support quarterly distributions. In addition, DCF is commonly used by the investment community because the market value of publicly traded partnerships is based, in part, on DCF and cash distributions paid to unitholders. FCF and excess/deficit cash flow are financial performance measures used by management in the allocation of capital and to assess financial performance. We believe that unitholders may use this metric to analyze our ability to manage leverage and return capital. We define FCF as net cash provided by operating activities adjusted for (i) net cash used in investing activities; (ii) contributions from MPC; (iii) contributions from noncontrolling interests and (iv) distributions to noncontrolling interests. We define excess/deficit cash flow as FCF adjusted for distributions to common and preferred unitholders. Distribution coverage ratio is a financial performance measure used by management to reflect the relationship between the partnership's financial operating performance and cash distribution capability. We define the distribution coverage ratio as the ratio of DCF attributable to GP and LP unitholders to total GP and LP distributions declared. Leverage ratio is a liquidity measure used by management, industry analysts, investors, lenders and rating agencies to analyze our ability to incur and service debt and fund capital expenditures.
