INFORMATION BY OPERATING SEGMENT

10. INFORMATION BY OPERATING SEGMENT

The Company has two reportable segments: Gas Utility and Gas Marketing. 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. Other components of the Company’s consolidated information include:

• unallocated corporate items, including certain debt and associated interest costs;

• Spire STL Pipeline LLC, a subsidiary of Spire constructing and planning the operation of a 65-mile FERC-regulated pipeline to deliver natural gas into eastern Missouri;

• Spire Storage, providing physical natural gas storage services; and

• Spire’s subsidiaries engaged in the operation of a propane pipeline, compression of natural gas, and risk management, among other activities.

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, sales of natural gas from Spire Missouri to Spire Marketing, propane transportation services provided by Spire NGL Inc. to Spire Missouri, and propane storage services provided by Spire Missouri to Spire NGL Inc.

Management evaluates the performance of the operating segments based on the computation of net economic earnings. Net economic 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 other non-recurring or unusual items such as certain regulatory, legislative, or GAAP standard-setting actions.
