Business Segment Information The Companys operations are principally managed based upon the products that are produced and are comprised of three operating segments, which are the same as the Companys reportable segments: Advanced Plastic Processing Technologies, Melt Delivery and Control Systems and Fluid Technologies. The factors for determining the Companys reportable segments include the manner in which management evaluates performance combined with the nature of the individual business activities. The Company evaluates the performance of its segments based on net sales and operating earnings. Operating earnings includes net sales to third parties, related cost of sales and operating expenses directly attributable to the segments. Operating earnings for each segment excludes items that are of a non-operating nature or are of a corporate or functional governance nature. Costs excluded from segment operating earnings include interest expense, income taxes and various corporate expenses such as transaction costs associated with the acquisition of certain businesses, stock-based compensation expense and other separately managed general and administrative costs. The effects of intersegment transactions have been eliminated. The Advanced Plastic Processing Technologies segment is a global leader in the manufacture, distribution and service of equipment and products used in the plastic technology and processing industry, including injection molding and extrusion applications with its principal operations located in the U.S., Germany, Italy, Czech Republic and India. The segment also sells specialty and peripheral equipment for plastic processing as well as replacement parts for machinery products. The Melt Delivery and Control Systems segment, which has major operations in the U.S., Canada, Germany and China, is a global leader in the manufacture of plastic delivery and precision control systems which are recurring, consumable sales for injection molding applications. The Melt Delivery and Control Systems segment sells highly engineered, technically advanced hot runner systems, process control systems, mold bases, mold components, aftermarket parts and related technologies and services for injection molding, as well as MRO supplies for plastic processing operations. The Fluid Technologies segment has major blending facilities in the U.S., The Netherlands and South Korea and is a leading manufacturer of premium coolants, lubricants, process cleaners and corrosion inhibitors that are used in a variety of metalworking industries.
