The Company’s cash equivalents are generally invested in Prime or U.S. government money market funds, which minimizes the credit risk. The Company believes that credit risk, with respect to accounts receivable, is limited as the receivables are primarily with the U.S. government.</font></div></div>

Areas of the financial statements where estimates may have the most significant effect include allowance for doubtful accounts, contractual and regulatory reserves, valuation and lives of tangible and intangible assets, impairment of long-lived assets, accrued liabilities, revenue recognition, bonus and other incentive compensation, stock-based compensation, realization of deferred tax assets, provisions for income taxes, and postretirement obligations.
