The following graph shows the cumulative, five-year total return for our common stock compared to three indices, each of which includes us. The Standard & Poor's 500 Stock Index includes 500 companies representing all major industries. The Standard & Poor's Healthcare Composite Index is a group of 45 companies involved in a variety of health care related businesses. Because the Standard & Poor's Healthcare Composite is heavily weighted by pharmaceutical companies, we believe that at times it may be less useful than the Hospital Management Index included below. We compiled the Hospital Management Index, which consists of publicly traded companies that have as their primary business the management of acute care hospitals and that have been in business for all five of the years shown. These companies are: HCA Inc. (HCA), Health Management Associates, Inc. (HMA), Tenet Healthcare Corporation (THC) and Universal Health Services, Inc. (UHS).
Performance data assumes that $100.00 was invested on December 31, 1999 in our common stock and each of the indices. The data assumes the reinvestment of all cash dividends and the cash value of other distributions. Stock price performance shown in the graph is not necessarily indicative of future stock price performance.
