A substantial portion of the financial statement activity associated with our DevCos is captured within the Gathering Systems and Fresh Water Delivery reportable segments. Although our unconsolidated investments are owned through certain DevCos, all financial statement activity associated with our unconsolidated investments is captured within the Investments in Midstream Entities reportable segment. As our DevCos represent VIEs, see the above reportable segments for our VIEs impact to the consolidated financial statements.

The Corporate segment includes all general Partnership activity not attributable to our DevCos.
