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

As of September 30, 2020, the amounts allocated to contract assets and contract liabilities on the Consolidated Balance Sheets are $264 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 30 years. Further, MPLX does not disclose variable consideration due to volume variability in the table below.

(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.
