OPERATING SEGMENTS

OPERATING SEGMENTS

Our revenues are derived from three operating segments: Gathering, Processing, and Terminalling and Transportation.

Our gathering systems include crude oil and natural gas pipeline gathering systems in the Bakken Region and the Green River Basin, Uinta Basin and Vermillion Basin in the Rockies Region, including:

• the High Plains System;

• the Williston Gathering System, which consists of a crude oil and natural gas gathering system located in the Williston Basin, North Dakota;

• the Uinta Basin Gathering System, which consists of natural gas gathering systems and compression assets located in northeastern Utah;

• the Green River System, which consists of an integrated natural gas gathering and transportation system;

• the Vermillion Gathering System, which consists of natural gas gathering and compression assets located in Southern Wyoming, northwest Colorado and northeast Utah; and

• equity method investments, which operate gathering pipeline and gas compression assets and transports natural gas to our natural gas processing facilities, located in the Uinta Basin.

Our Processing segment consists of gas processing and fractionation complexes, including:

• the Vermillion processing complex;

• the Uinta Basin processing complex;

• the Blacks Fork processing complex fractionation facility; and

• the Emigrant Trail processing complex.

Our Terminalling and Transportation segment consists of:

• crude oil and refined products terminals and storage facilities in the western and midwestern U.S. that are supplied by Tesoro-owned and third-party pipelines, trucks and barges;

• marine terminals in California that load and unload vessels;

• pipelines, which transport products and crude oil from Tesoro’s refineries to nearby facilities in Salt Lake City and Los Angeles and a 50% fee interest in a pipeline that transports jet fuel from Tesoro’s Los Angeles refinery to the Los Angeles International Airport;

• a regulated common carrier products pipeline and a jet fuel pipeline to the Salt Lake City International Airport

• a rail-car unloading facility in Washington;

• a petroleum coke handling and storage facility in Los Angeles; and

• a regulated common carrier refined products pipeline system

Our revenues are generated from commercial agreements we have entered into with Tesoro, under which Tesoro pays us fees, and from third-party contracts for gathering crude oil and natural gas, processing natural gas and distributing, transporting and storing crude oil, refined products, natural gas and NGLs. The commercial agreements with Tesoro are described in Note 3. We do not have any foreign operations.

The operating segments adhere to the accounting polices used for our consolidated financial statements, as described in Note 1. Our operating segments are strategic business units that offer different services in different geographical locations. We evaluate the performance of each segment based on its respective operating income. Certain general and administrative expenses and interest and financing costs are excluded from segment operating income as they are not directly attributable to a specific operating segment. Identifiable assets are those used by the segment, whereas other assets are principally cash, deposits and other assets that are not associated with a specific operating segment.
