19.                Segment Information

In accordance with FASB ASC 280, “Disclosures about Segments of an Enterprise and related information”, the Company determined it has two reportable segments - avionics government and avionics commercial. There are no inter-segment revenues.

The Company is organized primarily on the basis of its avionics products.  The avionics government segment consists primarily of the design, manufacture, and sale of test equipment to the U.S. and foreign governments and militaries either directly or through distributors.  The avionics commercial segment consists of design, manufacture, and sale of test equipment to domestic and foreign airlines, directly or through commercial distributors, and to general aviation repair and maintenance shops. The Company develops and designs test equipment for the avionics industry and as such, the Company’s products and designs cross segments.

Management evaluates the performance of its segments and allocates resources to them based on gross margin. The Company’s general and administrative costs and sales and marketing expenses, and engineering costs are not segment specific. As a result, all operating expenses are not managed on a segment basis.  Net interest includes expenses on debt and income earned on cash balances, both maintained at the corporate level. Segment assets include accounts receivable and work-in-process inventory. Asset information, other than accounts receivable and work-in-process inventory, is not reported, since the Company does not produce such information internally.  All long-lived assets are located in the U.S.
