(4) Discontinued Operations

The Company’s discontinued operations include a railroad construction and repair business (referred to herein as railroad), environmental remediation operations and certain concrete paving operations. The railroad business involved building and repairing railroad sidings. The environmental remediation operations primarily involved the repair of retaining walls along highways in Kentucky and the removal and remediation of underground fuel storage tanks. The railroad and environmental remediation operations were sold in 2012 in separate transactions for aggregate proceeds of $3.1 million. The concrete paving operations were wound down in 2013 and all assets had been sold in 2014. The results of these operations have been removed from the results of continuing operations for all periods presented. Prior to recognition as discontinued operations, all of these businesses were included in the East region’s operations.

Debt and interest expense were not allocated to these businesses since there was no debt specifically attributable to the operations. The discontinued businesses are organized within a limited liability company that passes its tax attributes for federal and state tax purposes to its parent company and is generally not subject to federal or state income tax. The railroad, environmental remediation and concrete paving businesses’ revenue and loss before income taxes, including an immaterial gain on sale, in fiscal years 2014, 2013 and 2012 are summarized below:
