Note 5. Business Segments, Concentration of Credit Risk and Significant Customers

 

The Company operates in one business segment and uses one measurement of profitability for its business.  Net revenue attributed to the United States and to all foreign countries is based on the geographical location of the customer.

 

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash, cash equivalents, short‑term and long‑term investments and accounts receivable. Cash, cash equivalents and short‑term and long-term investments are deposited with high credit‑quality institutions.

 

The Company recognized revenue from shipment of ICs and licensing of its technologies to customers by geographical location as follows (in thousands):
