OPERATING SEGMENTS

    The Company has two operating segments, the FSG and the ETG. The Company's operating segment reporting structure is consistent with how management reviews the business, makes investing and resource decisions and assesses operating performance. Additionally, characteristics such as similarity of products, customers, economic characteristics and various other factors are considered when identifying the Company's operating segments.

The FSG designs and manufactures jet engine and aircraft component replacement parts, which are approved by the FAA. In addition, the FSG repairs, overhauls and distributes jet engine and aircraft components, avionics and instruments for domestic and foreign commercial air carriers and aircraft repair companies as well as military and business aircraft operators. The FSG also manufactures and sells specialty parts as a subcontractor for aerospace and industrial original equipment manufacturers and the U.S government. Additionally, the FSG is a leading supplier, distributor, and integrator of military aircraft parts and support services primarily to the U.S. Department of Defense, defense prime contractors, and foreign military organizations allied with the U.S. Further, the FSG is a leading manufacturer of advanced niche components and complex composite assemblies for commercial aviation, defense and space applications. The FSG also engineers, designs and manufactures thermal insulation blankets and parts as well as removable/reusable insulation systems for aerospace, defense, commercial and industrial applications; manufactures expanded foil mesh for lightning strike protection in fixed and rotary wing aircraft; distributes aviation electrical interconnect products and electromechanical parts; overhauls industrial pumps, motors, and other hydraulic units with a focus on the support of legacy systems for the U.S. Navy; performs tight-tolerance machining, brazing, fabricating and welding services for aerospace, defense and other industrial applications; and designs, manufactures and distributes emergency descent devices ("EDDs") and personnel and cargo parachute products.

    The ETG collectively designs, manufactures and sells various types of electronic, data and microwave, and electro-optical products, including infrared simulation and test equipment, laser rangefinder receivers, electrical power supplies, back-up power supplies, power conversion products, underwater locator beacons, emergency locator transmission beacons, flight deck annunciators, panels, indicators, electromagnetic and radio frequency interference shielding and filters, high power capacitor charging power supplies, amplifiers, traveling wave tube amplifiers, photodetectors, amplifier modules, microwave power modules, flash lamp drivers, laser diode drivers, arc lamp power supplies, custom power supply designs, cable assemblies, high voltage power supplies, high voltage interconnection devices and wire, high voltage energy generators, high frequency power delivery systems; memory products, including three-dimensional microelectronic and stacked memory, static random-access memory (SRAM) and electronically erasable programmable read-only memory (EEPROM); harsh environment electronic connectors and other interconnect products, RF and microwave amplifiers, transmitters, and receivers and integrated assemblies, sub-assemblies and components; RF sources, detectors and controllers, wireless cabin control systems, solid state power distribution and management systems, proprietary in-cabin power and entertainment components and subsystems, cockpit displays and other avionics components, crashworthy and ballistically self-sealing auxiliary fuel systems,

nuclear radiation detectors, communications and electronic intercept receivers and tuners, fuel level sensing systems, high-speed interface products that link devices, high performance active antenna systems and airborne antennas for commercial and military aircraft, precision guided munitions, other defense applications and commercial uses; silicone material for a variety of demanding applications; precision power analog monolithic, hybrid and open frame components; high-reliability ("Hi-Rel") ceramic-to-metal feedthroughs and connectors, technical surveillance countermeasures (TSCM) equipment to detect devices used for espionage and information theft; rugged small-form factor embedded computing solutions; custom high power filters and filter assemblies; test sockets and adapters for both engineering and production use of semiconductor devices; radiation assurance services and products; and Hi-Rel, complex, passive electronic components and rotary joint assemblies for mostly aerospace and defense applications.

    The Company’s operating segments offer distinctive products and services that are marketed through different channels. They are managed separately because of their unique technology and service requirements.

Segment Profit or Loss

The financial results of the Company’s operating segments are reported on the same basis used internally by its Chief Operating Decision Maker (“CODM”). The Company’s Co-Chief Executive Officers serve together as the CODM. The primary measure used by the CODM and management to review and assess segment performance and to make resource allocation and business direction decisions is segment operating income. The CODM uses segment operating income to allocate resources, including personnel and financial resources, among the Company’s operating segments, primarily as part of the annual planning process. Segment operating income is also used to monitor segment performance compared to prior periods, budgeted expectations, and anticipated future results. The Company generally accounts for intersegment net sales as if the sales were to third parties at current market prices, and any such net sales and associated profit are eliminated in consolidation. The accounting policies of the Company’s operating segments are consistent with those described in Note 1, Summary of Significant Accounting Policies.
