Noncontrolling Interest [Abstract] |
Master Limited Partnership | MASTER LIMITED PARTNERSHIP We own the general partner and a majority limited partner interest in MPLX, which owns and operates crude oil and light product transportation and logistics infrastructure as well as gathering, processing and fractionation assets. We control MPLX through our ownership of the general partner interest. As of June 30, 2022, we owned approximately 64 percent of the outstanding MPLX common units. Unit Repurchase Program On November 2, 2020, MPLX announced the board authorization of a unit repurchase program for the repurchase of up to $1.0 billion of MPLX’s outstanding common units held by the public. Total unit repurchases were as follows for the respective periods:

Cash paid for common units repurchased | $ | 35 |  |  | $ | 155 |  |  | $ | 135 |  |  | $ | 310 |
Average cost per unit | $ | 33.74 |  |  | $ | 27.40 |  |  | $ | 32.48 |  |  | $ | 26.02 |
As of June 30, 2022, MPLX had $202 million remaining under its unit repurchase authorization. Agreements We have various long-term, fee-based commercial agreements with MPLX. Under these agreements, MPLX provides transportation, storage, distribution and marketing services to us. With certain exceptions, these agreements generally contain minimum volume commitments. These transactions are eliminated in consolidation but are reflected as intersegment transactions between our Refining & Marketing and Midstream segments. We also have agreements with MPLX that establish fees for operational and management services provided between us and MPLX and for executive management services and certain general and administrative services provided by us to MPLX. These transactions are eliminated in consolidation but are reflected as intersegment transactions between our Corporate and Midstream segments. Noncontrolling Interest As a result of equity transactions of MPLX, we are required to adjust non-controlling interest and additional paid-in capital. Changes in MPC’s additional paid-in capital resulting from changes in its ownership interests in MPLX were as follows:
| Three Months Ended June 30, |  | Six Months Ended June 30,
