If we are unable to enter into, maintain and renew managed care contractual arrangements on competitive terms, if we experience material reductions in the contracted rates we receive from managed care payers or if we have difficulty collecting from managed care payers, our results of operations could be adversely affected.

Our level of indebtedness could, among other things, adversely affect our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or our industry, and prevent us from meeting our obligations under the agreements relating to our indebtedness.

USPI and our hospital-based joint ventures depend on existing relationships with key health system partners. If we are unable to maintain synergistic relationships with these systems, or enter into new relationships, we may be unable to implement our business strategies successfully.
