Concentration of Credit Risk and Significant Customers

Concentration of Credit Risk and Significant Customers        The Company manages its credit risk associated with exposure to distributors and direct customers on outstanding accounts receivable through the application of credit approvals and other monitoring procedures. Credit sales, which are mainly on credit terms of 30 to 60 days, are only made to customers who meet the Company's credit standards, while sales to new customers or customers with low credit ratings are usually made on an advance payment basis. The Company closely monitors the aging of accounts receivable from its distributors and direct customers, and regularly reviews their financial positions, where available.

        Significant customers are those that represent 10% or more of revenue or accounts receivable and are set forth in the following table:
