Segment Information

Greenbrier operates in three reportable segments: Manufacturing; Wheels, Repair & Parts; and Leasing & Services. The accounting policies of the segments are described in the summary of significant accounting policies in the Consolidated Financial Statements contained in the Company’s 2013 Annual Report on Form 10-K. Performance for each of these segments is evaluated based on earnings (loss) from operations. Corporate includes selling and administrative costs not directly related to goods and services and certain costs that are intertwined among segments due to the Company’s integrated business. Greenbrier’s management does not allocate Interest and foreign exchange or Income tax benefit (expense) for either external or internal reporting purposes. Intersegment sales and transfers are valued as if the sales or transfers were to third parties. Related revenue and margin are eliminated in consolidation and therefore are not included in consolidated results in the Company’s Consolidated Financial Statements.

The information in the following table is derived directly from the segments’ internal financial reports used for corporate management purposes.
