Nature of Operations | Note 1 — Nature of Operations The Company operates in three reportable segments: Manufacturing; Maintenance Services; and Leasing & Management Services. The segments are operationally integrated. The Manufacturing segment, which currently operates from facilities in the U.S., Mexico, Poland, Romania and Turkey, produces double-stack intermodal railcars, tank cars, conventional railcars, automotive railcar products and marine vessels. The Maintenance Services segment performs wheel and axle servicing, railcar maintenance and produces a variety of parts for the rail industry in North America. The Leasing & Management Services segment, which includes GBX Leasing, owns approximately 12,200 railcars as of August 31, 2022. The Company also provides management services for approximately 408,000 railcars for railroads, shippers, carriers, institutional investors and other leasing and transportation companies in North America as of August 31, 2022. Through unconsolidated affiliates the Company produces rail and industrial components and has an ownership stake in a railcar manufacturer in Brazil. In 2022 the Company renamed two of its reportable segments to more prominently display the nature of the customer solutions it provides and markets in which it operates. The new names of its reportable segments are Manufacturing (unchanged), Maintenance Services (previously Wheels, Repair & Parts), and Leasing & Management Services (previously Leasing & Services). The name changes have no impact on the organization’s reporting structure nor on financial information previously reported. Separately, effective September 1, 2021, the Company changed its measurement basis for allocating syndication revenue between the Manufacturing and Leasing & Management Services reportable segments. This change in measurement reflects the information currently used by management to assess the Company's operating performance in accordance with its refined leasing strategy and has no impact to the Company’s total consolidated revenue. Segment results for the prior periods have been recast to conform to the current period presentation.
