Segment Reporting Disclosure [Text Block] | NOTE 15— The Company is organized into reporting segments based on the nature of the products offered and business activities from which it earns revenues and incurs expenses for which discrete financial information is available and regularly reviewed by the Company’s chief operating decision maker. The Company’s segments and their product and service offerings are summarized below: Heavy Fabrications The Company provides large, complex and precision fabrications to customers in a broad range of industrial markets. The Company’s most significant presence is within the U.S. wind energy industry, although it has diversified into other industrial markets in order to improve capacity utilization, reduce customer concentrations, and reduce exposure to uncertainty related to governmental policies currently impacting the U.S. wind energy industry. Within the U.S. wind energy industry, the Company provides steel towers and adapters primarily to wind turbine manufacturers. Production facilities, located in Manitowoc, Wisconsin and Abilene, Texas, are situated in close proximity to the primary U.S. domestic wind energy and equipment manufacturing hubs. The two Gearing The Company provides gearing, gearboxes and precision machined components to a broad set of customers in diverse markets including surface and underground mining, wind energy, steel, material handling, infrastructure, onshore and offshore oil and gas fracking and drilling, marine, defense, and other industrial markets. The Company has manufactured loose gearing, gearboxes and systems, and provided heat treat services for aftermarket and OEM applications for a century. The Company uses an integrated manufacturing process, which includes machining and finishing processes in addition to gearbox repair in Cicero, Illinois, and heat treatment and gearbox repair in Neville Island, Pennsylvania. Industrial Solutions The Company provides supply chain solutions, light fabrication, inventory management and kitting and assembly services, primarily serving the combined cycle natural gas turbine market. The Company has recently expanded into the U.S. wind power generation market, by providing tower internals kitting solutions for on-site installations, as OEMs domesticate their supply chain due to lead time and reliability issues. The Company leverages a global supply chain to provide instrumentation and controls, valve assemblies, sensor devices, fuel system components, electrical junction boxes and wiring, and electromechanical devices. The Company also provides packaging solutions and fabricates panels and sub-assemblies to reduce customers’ costs and improve manufacturing velocity and reliability. Corporate “Corporate” includes the assets and selling, general and administrative expenses of the Company’s corporate office. “Eliminations” comprises adjustments to reconcile segment results to consolidated results.
