Use of Estimates in the Preparation of Financial Statements Cash and Cash Equivalents Fair Value of Financial Instruments Concentration of Credit Risk 250,000 We have no significant off-balance sheet concentrations of credit risk such as foreign exchange contracts, options contracts or other foreign hedging arrangements. We maintain the majority of our cash balances with one financial institution in the form of demand deposits. Accounts receivable are typically unsecured and are derived from transactions with and from entities in the healthcare industry primarily located in the United States. Accordingly, we may be exposed to credit risk generally associated with the healthcare industry. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments.
