The most significant estimates relate to receivable allowances, intangible assets, income taxes and related tax asset valuation allowances, useful lives of property and equipment, contingencies, revenue recognition and the assessment of litigation. In addition, healthcare industry reforms and reimbursement practices will continue to impact the Company's operations and the determination of contractual and other allowance estimates.
