Information by Operating Segment

10. INFORMATION BY OPERATING SEGMENT

The Company has three reportable segments: Gas Utility, Gas Marketing, and Midstream. The Gas Utility segment is the aggregation of the operations of the Utilities. The Gas Marketing segment includes the results of Spire Marketing, a subsidiary engaged in the non-regulated marketing of natural gas and related activities, including utilizing natural gas storage contracts for providing natural gas sales. The Midstream segment includes Spire Storage, Spire STL Pipeline and Spire MoGas Pipeline, which are subsidiaries engaged in the storage and transportation of natural gas. Other components of the Company’s consolidated information include Spire’s subsidiaries engaged in the operation of a natural gas liquids pipeline and risk management, among other activities, and unallocated corporate items, including certain debt and associated interest costs.

Accounting policies are described in Note 1, Summary of Significant Accounting Policies. Intersegment transactions include sales of natural gas from Spire Marketing to Spire Missouri, Spire Alabama and Spire Storage, storage services from Spire Storage to Spire Missouri and Spire Marketing, and natural gas transportation services provided by Spire STL Pipeline and Spire MoGas Pipeline to Spire Missouri and Spire Marketing.

Management evaluates the performance of the operating segments based on the computation of adjusted earnings. Adjusted earnings exclude from reported net income the after-tax impacts of fair value accounting and timing adjustments associated with energy-related transactions, the impacts of acquisition, divestiture and restructuring activities, and the largely non-cash impacts of impairments and other non-recurring or unusual items such as certain regulatory, legislative, or GAAP standard-setting actions.
