3. CONCENTRATION OF CREDIT RISK Financial instruments that potentially subject us to concentrations of credit risk consist principally of accounts receivable from sales in the ordinary course of business. Management reviews our accounts receivable for potential doubtful accounts and maintains an allowance for estimated uncollectible amounts. Generally, no collateral is received from customers for our accounts receivable. Our policy is to write-off uncollectable amounts at the time it is determined that collection will not occur. During the nine months ended July 31, 2012, one customer in the Display Technology Segment represented 100% of that segment’s revenue and 99.3% of total net revenue. During the nine months ended July 31, 2012, one customer in the Encryption Products and Services Segment represented 42% of that segment’s revenue. |
