Revenue, Remaining Performance Obligation, Expected Timing of Satisfaction [Table Text Block]

The table below includes estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period.

As of December 31, 2019, the amounts allocated to contract assets and contract liabilities on the Consolidated Balance Sheets are $220 million and are reflected in the amounts below. This will be recognized as revenue as the obligations are satisfied, which is expected to occur over the next 24 years. Further, MPLX does not disclose variable consideration due to volume variability in the table below.

(In millions)
2020	$	1,717
2022	1,693
2022	1,640
2023	1,555
2024 and thereafter	5,317
Total revenue on remaining performance obligations(1)(2)(3)	$	11,922

(1) All fixed consideration from contracts with customers is included in the amounts presented above. Variable consideration that is constrained or not required to be estimated as it reflects our efforts to perform is excluded.

(2) Arrangements deemed implicit leases are included in “Rental income” and are excluded from this table.

(3)

Only minimum volume commitments that are deemed fixed are included in the table above. MPLX has various minimum volume commitments in processing arrangements that vary based on the actual Btu content of the gas received. These amounts are deemed variable consideration and are excluded from the table above.
