Segmental Information We classify our operations into two core business segments, Gas Cylinders and Elektron, based primarily on shared economic characteristics for the nature of the products and services; the nature of the production processes; the type or class of customer for their products and services; the methods used to distribute their products or provide their services; and the nature of the regulatory environment. The Company has six identified business units, which aggregate into the two reportable segments. Luxfer Gas Cylinders and Luxfer Superform aggregate into the Gas Cylinders segment, and Luxfer MEL Technologies, Luxfer Magtech, Luxfer Graphic Arts and Luxfer Czech Republic (1) aggregate into the Elektron segment. A summary of the operations of the segments is provided below: Gas Cylinders segment Our Gas Cylinders segment manufactures and markets specialized products using aluminum, titanium and carbon composites, including pressurized cylinders for use in various applications including self-contained breathing apparatus (SCBA) for firefighters, containment of oxygen and other medical gases for healthcare, alternative fuel vehicles, and general industrial. The segment also forms lightweight aluminum and titanium panels into highly complex shapes that are used mainly in the transportation industry. Elektron segment Our Elektron segment focuses on specialty materials based primarily on magnesium and zirconium, with key product lines including advanced lightweight magnesium alloys with a variety of uses across a variety of industries; magnesium powders for use in countermeasure flares, as well as heater meals; photoengraving plates for graphic arts; and high-performance zirconium-based materials and oxides used as catalysts and in the manufacture of advanced ceramics, fiber-optic fuel cells, and many other performance products. Other Other primarily represents unallocated corporate expense and includes non-service related defined benefit pension cost / credit. Management monitors the operating results of its reportable segments separately for the purpose of making decisions about resource allocation and performance assessment. Segment performance is evaluated by the chief operating decision maker, who is responsible for allocating resources and assessing performance of the operating segments as the CEO, using adjusted EBITA (2) and adjusted EBITDA, which we defined as segment income and is based on operating income adjusted for share-based compensation expense; qualifying restructuring charges; impairment charges; acquisition and disposal related gains and costs; loss on disposal of property, plant and equipment; depreciation and amortization; and unwind of discount on deferred consideration. 14. Segmental Information (continued) Unallocated assets and liabilities include those which are held on behalf of the Company and cannot be allocated to a segment, such as taxation, investments, cash, retirement benefits obligations, bank and other loans and holding company assets and liabilities.
