Risks and Uncertainties [Abstract] |
Significant Customer and Geographic Information | Concentration of Credit Risk, Significant Customers and Geographic Information Financial instruments, which potentially subject the Company to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable. Collateral is generally not required for customer receivables. The Company limits its exposure to credit loss by placing its cash with high credit quality financial institutions. At times, such deposits may be in excess of insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. Significant Customers The Company markets its products and services to manufacturers of a wide range of electronic devices (Note 1). The Company sells its products both directly to customers and through third-party distributors, both of which are referred to as the Company’s customers (Note 15). The Company makes periodic evaluations of the credit worthiness of its customers. Customers comprising greater than 10% of net revenues for each of the periods presented are as follows:

| Amount |  | % of total net revenue |  | Amount |  | % of total net revenue |  | Amount |  | % of total net revenue

The products shipped to individual countries representing greater than 10% of net revenue for each of the periods presented are as follows:

Percentage of total net revenue |  |  |  |  |
China | 60 | % |  | 63 | % |  | 71 | %
The determination of which country a particular sale is allocated to is based on the destination of the product shipment. No other individual country accounted for more than 10% of net revenue during these periods. Although a large percentage of the Company’s products is shipped to Asia, and in particular, China, the Company believes that a significant number of the systems designed by customers and incorporating the Company’s semiconductor products are subsequently sold outside Asia to Europe, Middle East, and Africa, or EMEA markets and North American markets.
