CY2018	us-gaap	Defined Benefit Plan Narrative Description Of Basis Used To Determine Overall Expected Long Term Rate Of Return On Assets Assumption DefinedBenefitPlanNarrativeDescriptionOfBasisUsedToDetermineOverallExpectedLongTermRateOfReturnOnAssetsAssumption	The overall expected long-term return on plan assets assumption is determined based on an asset rate-of-return modeling tool developed by a third-party investment group. The tool utilizes underlying assumptions based on actual returns by asset category and inflation and takes into account our asset allocation to derive an expected long-term rate of return on those assets. Capital market assumptions reflect the long-term capital market outlook. The assumptions for equity and fixed income investments are developed using a building-block approach, reflecting observable inflation information and interest rate information available in the fixed income markets. Long-term assumptions for other asset categories are based on historical results, current market characteristics and the professional judgment of our internal and external investment teams.

Such changes in asset allocation are intended to allocate additional assets to the fixed income asset class should the funded status improve. The fixed income asset class shall be invested in such a manner that its interest rate sensitivity correlates highly with that of the plans’ liabilities. Other asset classes are intended to provide additional return with associated higher levels of risk.

The amendment was effective January 1, 2019. We do not expect the application of this accounting standard update to have a material impact on our consolidated financial statements.  </font></div><div style="line-height:120%;padding-top:12px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">ASU 2017-12, Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities</font><font style="font-family:inherit;font-size:10pt;font-style:italic;"> </font></div><div style="line-height:120%;padding-top:4px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In August 2017, the FASB issued an ASU to amend the hedge accounting rules to simplify the application of hedge accounting guidance and better portray the economic results of risk management activities in the financial statements. The guidance expands the ability to hedge nonfinancial and financial risk components, reduces complexity in fair value hedges of interest rate risk, eliminates the requirement to separately measure and report hedge ineffectiveness and eases certain hedge effectiveness assessment requirements. The guidance was effective January 1, 2019. We do not expect the application of this accounting standard update to have a material impact on our consolidated financial statements.  </font></div><div style="line-height:120%;padding-top:12px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">ASU 2017-04, Intangibles - Goodwill and Other - Simplifying the Test for Goodwill Impairment</font><font style="font-family:inherit;font-size:10pt;font-style:italic;"> </font></div><div style="line-height:120%;padding-top:4px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In January 2017, the FASB issued an ASU which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the new guidance, the recognition of an impairment charge is calculated based on the amount by which the carrying amount exceeds the reporting unit’s fair value, which could be different from the amount calculated under the current method using the implied fair value of the goodwill; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The guidance should be applied on a prospective basis, and is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. </font></div><div style="line-height:120%;padding-top:12px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">ASU 2016-13, Credit Losses - Measurement of Credit Losses on Financial Instruments</font><font style="font-family:inherit;font-size:10pt;font-style:italic;"> </font></div><div style="line-height:120%;padding-top:4px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In June 2016, the FASB issued an ASU related to the accounting for credit losses on certain financial instruments. The guidance requires that for most financial assets, losses be based on an expected loss approach which includes estimates of losses over the life of exposure that considers historical, current and forecasted information. Expanded disclosures related to the methods used to estimate the losses as well as a specific disaggregation of balances for financial assets are also required. The change is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. We do not expect application of this ASU to have a material impact on our consolidated financial statements. </font></div><div style="line-height:120%;padding-top:12px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">ASU 2016-02 Leases</font><font style="font-family:inherit;font-size:10pt;font-style:italic;"> </font><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">and related updates</font></div><div style="line-height:120%;padding-top:4px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued an ASU requiring lessees to record virtually all leases on their balance sheets. The ASU also requires expanded disclosures to help financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. For lessors, this amended guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. The guidance will be effective for fiscal years beginning after December 15, 2018, and interim periods within those years. As of January 1, 2019, we have transitioned to the new guidance. </font></div><div style="line-height:120%;padding-top:12px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">As part of implementing this standard, we evaluated the impact of this standard on our financial statements, disclosures, internal controls and accounting policies. This evaluation process included reviewing all forms of leases, performing a completeness assessment over the lease population and analyzing the practical expedients in order to determine the best path of implementing changes to existing processes and controls. We have implemented a third-party supported lease accounting information system to account for our lease population in accordance with this new standard and established internal controls over the new system. We expect that adoption of the standard will result in the recognition of right-of-use assets and lease liabilities for operating leases on January 1, 2019 in the range of </font><font style="font-family:inherit;font-size:10pt;">$2.5 billion</font><font style="font-family:inherit;font-size:10pt;"> to </font><font style="font-family:inherit;font-size:10pt;">$3.0 billion</font><font style="font-family:inherit;font-size:10pt;">. The adoption of ASC 842 will not have a material impact on our consolidated statements of income or cash flows, except for the potential effects from lease modifications where MPLX is the lessor as discussed below.</font></div><div style="line-height:120%;padding-top:12px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In addition, based on the changes presented in the standard, MPLX, as a lessor, may be required to re-classify existing operating leases to sales-type leases upon modification and related reassessment of the leases. If such modification were to occur, it may result in a de-recognition of existing assets, recognition of a receivable in the amount of the present value of fixed payments expected to be received by MPLX under the lease, and recognition of a corresponding gain or loss in the period of change.</font></div></div>

We have elected to use the output measure of progress to recognize revenue based on the units delivered, processed or transported. The transaction prices in our Midstream contracts often have both fixed components, related to minimum volume commitments, and variable components, which are primarily dependent on volumes.
