CONCENTRATIONS AND UNCERTAINTIES CONCENTRATIONS AND UNCERTAINTIES
Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents, trade accounts receivable, and short-term investments. The Company holds cash and cash equivalents with balances that exceed FDIC insured limits. Cash maintained in excess of these limits is on deposit with a large, national bank. Accordingly, the Company does not have depository exposure to regional banks. In addition, the Company holds cash at a bank in France that is not FDIC-insured. Historically, the Company has not experienced any losses in such accounts, and management believes that the financial institutions at which its cash is held are stable; however, no assurances can be provided. While the Company may be exposed to credit losses due to the nonperformance of its counterparties, the Company does not expect the settlement of these transactions to have a material effect on its results of operations, cash flows, or financial condition.
