12. Segment Information

The Company’s reportable segments are Performance Materials, Thermal/Acoustical Metals, and Thermal/Acoustical Fibers. The Performance Materials segment reports the results of Industrial Filtration, Industrial Thermal Insulation, and Life Sciences Filtration businesses. The Thermal/Acoustical Metals segment reports the results of the Company’s metal-based automotive business. The Thermal/Acoustical Fibers segment reports the results of the Company’s fiber-based automotive business. Other Products and Services (“OPS”) includes Life Sciences Vital Fluids.

During the quarter ended March 31, 2012, the Thermal/Acoustical business reorganized its management reporting structure. Prior to this reorganization, the Thermal/Acoustical business was comprised of one operating segment for financial reporting purposes. The Company now manages and measures its Thermal/Acoustical business performance in two distinct operating segments: Thermal/Acoustical Metals and Thermal/Acoustical Fibers. The new segments reflect the way the Company’s Chief Operating Decision Maker (“CODM”) reviews operating results for the purposes of allocating resources and assessing performance.

On June 29, 2011, the Company sold its Affinity business, which had been included within OPS. Affinity designed and manufactured high precision, specialty engineered temperature-control equipment for semiconductor, pharmaceutical, life sciences and industrial applications. As a result of the sale, the Condensed Consolidated Financial Statements have been retroactively restated to reflect Affinity as a discontinued operation and the following segment information excludes Affinity’s net sales and operating income for all periods presented.

Prior period segment amounts throughout the notes to the Condensed Consolidated Financial Statements have been reclassified to give effect to the new segment structure and for discontinued operations. The reclassification of historical business segment information had no impact on the consolidated financial results.

Performance Materials Segment

The Performance Materials segment includes filtration media solutions for air, fluid power, and industrial applications (“Industrial Filtration”), air and liquid life science applications (“Life Sciences Filtration”), and industrial thermal insulation solutions for building products, appliances, and energy and industrial markets (“Industrial Thermal Insulation”).

Industrial Filtration products include LydAir^® MG (Micro-Glass) Air Filtration Media, LydAir^® MB (Melt Blown) Air Filtration Media, LydAir^® SC (Synthetic Composite) Air Filtration Media, and Arioso™ Membrane Composite Media. These products constitute the critical media component of clean-air systems for applications in clean-space, commercial, industrial and residential HVAC, power generation, and industrial processes. Lydall has leveraged its extensive technical expertise and applications knowledge into a suite of media products covering the vast liquid filtration landscape across the engine and industrial fields. The LyPore^® Liquid Filtration Media and activated carbon containing ActiPure^® Filtration Media series address a variety of application needs in fluid power including hydraulic filters, air-water and air-oil coalescing, industrial fluid processes, diesel filtration and fuel filtration.

Life Sciences Filtration products include the LyPore^® and ActiPure^® Filtration Media developed to meet the requirements of life science applications including biopharmaceutical pre-filtration and clarification, diagnostic and analytical testing, respiratory protection, life protection, medical air filtration, drinking water filtration and high purity process filtration such as that found in food and beverage and medical applications. Lydall also offers Solupor^® Membrane specialty microporous membranes that are utilized in various markets and applications including air and liquid filtration and transdermal drug delivery. Solupor^® membranes are made from ultra-high molecular weight polyethylene and incorporate a unique combination of mechanical strength, chemical inertness, and high porosity in a unique open structure.

Industrial Thermal Insulation products are high performance nonwoven veils, papers, mats and specialty composites for the building products, appliance, and energy and industrial markets. The Manniglas^® Thermal Insulation brand is diverse in its product application ranging from high temperature seals and gaskets in ovens and ranges to specialty veils for HVAC and cavity wall insulation. appLY^® Mat Needled Glass Mats have been developed to expand Lydall’s high temperature technology portfolio for broad application into the appliance market and supplements the Lytherm^® Insulation Media product brand, traditionally utilized in the industrial market for kilns and furnaces used in metal processing. Lydall’s Cryotherm^® Super-Insulating Media, CRS-Wrap^® Super-Insulating Media and Cryo-Lite^TM Cryogenic Insulation products are industry standards for state-of-the-art cryogenic insulation designs used by manufacturers of cryogenic equipment for liquid gas storage, piping, and transportation.

Thermal/Acoustical Metals Segment

The Thermal/Acoustical Metals segment offers a full line of innovative engineered products to assist in noise and heat abatement within the transportation sector. Lydall products are found in the interior (dash insulators), underbody (wheel well, fuel tank, exhaust) and under hood (engine compartment) of cars, trucks, SUV’s, heavy duty trucks and recreational vehicles.

Thermal/Acoustical Metals segment products are stamped metal combinations which provide thermal and acoustical shielding solutions for the global automotive and truck markets. Thermal/Acoustical Metals products include AMS^® which is an all metal shield designed to be used in various vehicle applications, and Direct Exhaust Mount Heat shields which are mounted to high temperature surfaces like exhaust down-pipes or engine manifolds.

Thermal/Acoustical Fibers Segment

The Thermal/Acoustical Fibers segment offers a full line of innovative engineered products to assist in noise and heat abatement within the transportation sector. Lydall products are found in the interior (dash insulators), underbody (wheel well, fuel tank, exhaust) and under hood (engine compartment) of cars, trucks, SUV’s, heavy duty trucks and recreational vehicles.

Thermal/Acoustical Fibers segment products offer thermal and acoustical insulating solutions comprised of organic and inorganic fiber composites for the automotive and truck markets primarily in North America. Lydall’s dBCore^® is a lightweight acoustical composite that emphasizes absorption principles over heavy-mass type systems. Lydall’s dBLyte^® is a high-performance acoustical barrier with sound absorption and blocking properties and can be used throughout a vehicle’s interior to minimize intrusive noise from an engine compartment and road. Lydall’s ZeroClearance^® is an innovative thermal solution that utilizes an adhesive backing for attachment and is ideal for protecting floor sheet metal from excessive exhaust heat. Lydall’s specially engineered wheel wells provide a solution with weight reduction and superior noise suppression capabilities over conventional designs.

Thermal/Acoustical Metals segment and Thermal/Acoustical Fibers segment operating results include allocations of certain costs shared between the segments.

Other Products and Services

The Life Sciences Vital Fluids business offers specialty products for blood filtration devices, blood transfusion single-use containers and bioprocessing single-use containers and products for containment of media, buffers and bulk intermediates used in biotech, pharmaceutical and diagnostic reagent manufacturing processes.
