These estimates and assumptions affect various matters, including our reported amounts of assets and liabilities in our consolidated balance sheets at the dates of the financial statements; our disclosure of contingent assets and liabilities at the dates of the financial statements; and our reported amounts of revenues and expenses in our consolidated statements of operations during the reporting periods. These estimates involve judgments with respect to numerous factors that are difficult to predict and are beyond management’s control. As a result, actual amounts could materially differ from these estimates.</span></div>

We have placed our cash and cash equivalents with one major financial institution. The cash in the financial institution is in excess of the amount insured by the Federal Deposit Insurance Corporation, or FDIC. Substantially all of our accounts receivable are due under fee-for-service contracts from third party payors, such as insurance companies and government-sponsored healthcare programs, or directly from patients. We continuously monitor collections and maintain an allowance for bad debts based upon our historical collection experience. In addition, we have notes receivable stemming from our factoring of accounts receivable as stated above. Companies with which we factor our receivables are well known established buyers of such instruments, have agreed to assume the full risk of their collection.</span></div>
