Certain statements contained herein that are not descriptions of historical facts are “forward-looking” statements (as such term is defined in the Private Securities Litigation Reform Act of 1995).  Because such statements include risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements due to factors including the following:

·changes in government reimbursement for our services due to the implementation of healthcare reform legislation, deficit reduction measures, and/or new payment policies (including, for example, the expiration of the moratorium limiting the full application of the 25 Percent Rule that would reduce our Medicare payments for those patients admitted to a long term acute care hospital from a referring hospital in excess of an applicable percentage admissions threshold) may result in a reduction in net operating revenues, an increase in costs and a reduction in profitability;

·the impact of the Bipartisan Budget Act of 2013, which establishes new payment limits for Medicare patients who do not meet specified criteria, may result in a reduction in net operating revenues and profitability of our long term acute care hospitals;

·the failure of our specialty hospitals to maintain their Medicare certifications may cause our net operating revenues and profitability to decline;

·the failure of our facilities operated as “hospitals within hospitals” to qualify as hospitals separate from their host hospitals may cause our net operating revenues and profitability to decline;

·a government investigation or assertion that we have violated applicable regulations may result in sanctions or reputational harm and increased costs;

·acquisitions or joint ventures may prove difficult or unsuccessful, use significant resources or expose us to unforeseen liabilities;

·our plans and expectations related to the Concentra acquisition, including expectations regarding the expected capital expenditures related to the acquisition, and our ability to realize anticipated synergies;

·private third-party payors for our services may undertake future cost containment initiatives that could limit our future net operating revenues and profitability;

·the failure to maintain established relationships with the physicians in the areas we serve could reduce our net operating revenues and profitability;

·shortages in qualified nurses, therapists, physicians, or other licensed providers could increase our operating costs significantly or limit our ability to staff our facilities;

·competition may limit our ability to grow and result in a decrease in our net operating revenues and profitability;

·the loss of key members of our management team could significantly disrupt our operations;

·the effect of claims asserted against us could subject us to substantial uninsured liabilities; and

·other factors discussed from time to time in our filings with the Securities and Exchange Commission, including factors discussed under the heading “Risk Factors” of our quarterly report on Form 10-Q and of the annual report on Form 10-K.

Except as required by applicable law, including the securities laws of the United States and the rules and regulations of the SEC, we are under no obligation to publicly update or revise any forward-looking statements, whether as a result of any new information, future events or otherwise. You should not place undue reliance on our forward-looking statements.
