Geographic Distribution of Revenues and Long Lived Assets from Continuing Operations

The following table below presents the Company's net revenue by end user for the periods presented:

	Three Months Ended September 30,
	2017		2016
Domestic (1)	$	89,678	$	73,527
International/Foreign Military Sales (2)	16,391		14,122
Total Net Revenue	$	106,069	$	87,649

(1) Domestic revenues consist of sales where the end user is within the U.S., as well as sales to prime defense contractor customers where the ultimate end user location is not defined. 

(2) International/Foreign Military Sales consist of sales to U.S. prime defense contractor customers where the end user is known to be outside the U.S., foreign military sales through the U.S. government, and direct sales to non-U.S. based customers intended for end use outside of the U.S.

The following table below presents the Company's net revenue by end application for the periods presented:

	Three Months Ended September 30,
	2017		2016
Radar (1)	$	36,540	$	37,489
Electronic Warfare (2)	28,008		20,979
Other (3)	41,521		29,181
Total Net Revenue	$	106,069	$	87,649

(1) Radar includes end-use applications where radio frequency signals are utilized to detect, track, and identify objects.

(2) Electronic Warfare includes end-use applications comprising the offensive and defensive use of the electromagnetic spectrum.

(3) Other products include all end markets other than Radar and Electronic Warfare. Examples include but are not limited to various commercial and other end-use applications and technologies, as well as various component and other sales where the end use is not specified.

The following table below presents the Company's net revenue by product grouping for the periods presented:

	Three Months Ended September 30,
	2017		2016
Components (1)	$	32,812	$	19,832
Modules and Sub-assemblies (2)	47,732		36,592
Integrated Subsystems (3)	25,525		31,225
Total Net Revenue	$	106,069	$	87,649

(1) Components include technology elements typically performing a single, discrete technological function, which when physically combined with other components may be used to create a module or sub-assembly. Examples include but are not limited to power amplifiers and limiters, switches, oscillators, filters, equalizers, digital and analog converters, chips, MMICs (monolithic microwave integrated circuits), and memory and storage devices.

(2) Modules and Sub-assemblies include combinations of multiple functional technology elements and/or components that work together to perform multiple functions but are typically resident on or within a single board or housing. Modules and sub-assemblies may in turn be combined to form an integrated subsystem. Examples of modules and sub-assemblies include but are not limited to embedded processing modules, embedded processing boards, switch fabric boards, high speed input/output boards, digital receiver boards, graphics and video processing and Ethernet and IO (input-output) boards, multi-chip modules, integrated radio frequency and microwave multi-function assemblies, tuners, and transceivers.

(3) Integrated Subsystems include multiple modules and/or subassemblies combined with a backplane or similar functional element and software to enable a solution. These are typically but not always integrated within a chassis and with cooling, power and other elements to address various requirements and are also often combined with additional technologies for interaction with other parts of a complete system or platform. Integrated subsystems also include spare and replacement modules and sub-assemblies sold as part of the same program for use in or with integrated subsystems sold by the Company.
