Segment Reporting [Abstract]  
Segment Information Segment 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 four identified business units, which aggregate into the two reportable Segments. Luxfer Gas Cylinders forms the Gas Cylinders Segment, and Luxfer MEL Technologies, Luxfer Magtech and Luxfer Graphic Arts aggregate into the Elektron Segment. The Superform business unit used to aggregate into the Gas Cylinders Segment but is now recognized within discontinued operations. A summary of the operations of the segments is provided below:
Gas Cylinders Segment
Our Gas Cylinders Segment manufactures and markets specialized highly-engineered cylinders using carbon composites and aluminum alloys, such as 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 applications.
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, including the following: (i) magnesium powders for use in countermeasure flares, as well as heater meals; (ii) photoengraving plates for graphic arts; and (iii) high-performance zirconium-based materials and oxides used as catalysts and in the manufacture of advanced ceramics, fiber-optic fuel cells, and many other high-performance products.
Other
Other, as used below, 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, the CEO, who is responsible for allocating resources and assessing performance of the operating segments, using adjusted EBITA(1) and adjusted EBITDA, which is defined as segment income, and is based on (i) operating income adjusted for share based compensation charges; (ii) loss on disposal of property, plant and equipment; (iii) restructuring charges; (iv) impairment charges; (v) acquisition and disposal related gains and costs; (vi) other charges; (vii) depreciation and amortization; and (viii) unwind of discount on deferred consideration.
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.
Financial information by reportable segment for the years ended December 31 is included in the following summary:
