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

	Three Months Ended March 31,				Nine Months Ended March 31,
	2018		2017		2018		2017
Components (1)	$	30,022	$	26,920	$	102,742	$	74,126
Modules and Sub-assemblies (2)	42,121		43,330		131,581		115,744
Integrated Subsystems (3)	44,193		37,067		105,994		103,110
Total Net Revenue	$	116,336	$	107,317	$	340,317	$	292,980

(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 sub-assemblies 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.

The geographic distribution of the Company’s long-lived assets is summarized as follows:

	U.S.		Europe		Asia Pacific		Eliminations		Total
