Legal Proceedings

The health care industry is subject to numerous laws and regulations of federal, state, and local governments. Penalties associated with violations of these laws and regulations include significant fines, exclusion from participating in publicly funded programs, and the repayment of previously collected revenues.

In the ordinary course of business we are involved in legal actions, some of which seek monetary damages, including claims for punitive damages, which are not covered by insurance. We have accrued liabilities for certain matters for which we deem the loss to be both probable and reasonably estimable, but the outcome of legal actions is inherently uncertain and our estimates of such losses could change as a result of further developments of these matters. For certain pending matters, accruals have not been established because such matters have not progressed sufficiently through discovery or factual development to enable us to reasonably estimate a range of possible loss.
