Such estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities in the consolidated financial statements and accompanying notes. The following are some, but not all, of such estimates: the determination of chargebacks, sales returns, rebates, billbacks, valuation of intangible and other assets acquired in business combinations, allowances for accounts receivable, accrued liabilities, stock-based compensation, valuation of inventory balances, the determination of useful lives for product rights and the assessment of expected cash flows used in evaluating goodwill and other long-lived assets for impairment. Actual results could differ from those estimates.</span></div>
