Operating Segments and Sales and Credit Concentrations

ARI operates in three reportable segments: manufacturing, railcar leasing and railcar services. These reportable segments are organized based upon a combination of the products and services offered and performance is evaluated based on revenues and segment earnings (loss) from operations. Intersegment revenues are accounted for as if sales were to third parties.

Manufacturing

Manufacturing consists of railcar manufacturing, and railcar and industrial component manufacturing. Revenues for railcars manufactured for the Company’s railcar leasing segment are not recognized in consolidated revenues as railcar sales, but rather lease revenues are recognized over the term of the lease. Earnings from operations for manufacturing include an allocation of selling, general and administrative costs, as well as profit for railcars manufactured for the Company’s railcar leasing segment based on revenue determined as described above. Intersegment revenues and profits are determined based on an estimated fair market value of the railcars manufactured for the Company’s railcar leasing segment, as if such railcars had been sold to a third party.

Railcar leasing

Railcar leasing consists of railcars manufactured by the Company and leased to third parties under operating leases. Earnings from operations for railcar leasing include an allocation of selling, general and administrative costs and also reflect origination fees paid to ARL associated with originating the lease to the Company’s leasing customers prior to the ARL Sale. The origination fees represented a percentage of the revenues from the lease over its initial term and were paid up front.

Railcar services

Railcar services consists of railcar repair services provided through the Company's various full service facilities or mini shops and mobile units. Earnings from operations for railcar services include an allocation of selling, general and administrative costs as well as certain operating costs related to this segment's use of a portion of the Company's tank railcar manufacturing facility to perform railcar services.
