Industry Segments [Abstract]

Industry Segments

6. Industry Segments

Our reportable segments are business units that offer different products and are managed separately because each business requires different technology and marketing strategies. Our reportable segments are: semiconductor equipment, microwave communications and video cameras.

We allocate resources and evaluate the performance of segments based on profit or loss from operations, excluding interest, corporate expenses and unusual gains or losses. Intersegment sales were not significant for any period.

Financial information by industry segment is as follows (in thousands):

A small number of customers historically have been responsible for a significant portion of our consolidated net sales. During the first quarter of fiscal 2012, two customers of the semiconductor equipment segment each represented more than 10% of consolidated net sales and, combined, they accounted for 59% of our total consolidated net sales. During the first quarter of fiscal 2011, two customers of the semiconductor equipment segment each represented more than 10% of consolidated net sales and, combined, they accounted for 52% of our total consolidated net sales.
