In 2019, we began aggregating the results of Delaware Supersystem activity, including New Delaware. Discrete financial information for New Delaware is no longer available and management now reviews aggregate Delaware Supersystem operating results.

In 2020, as a result of the high degree of operational integration of our Permian gathering and processing assets and management’s increased focus and review of combined operating results within our Permian Midland and Permian Delaware regions, we further aggregated our New Midland and Permian Supersystem reporting units into the Permian Midland and Permian Delaware reporting units, respectively.
