Part 1. We cannot predict the outcome of these suits with certainty, and we are incurring expenses in defense of
these matters. In addition, recent court decisions and legislative activity may increase our exposure for any of
these types of claims. Therefore, these legal actions could have a material adverse effect on our financial
position, results of operations and cash flows.
Cautionary Statements
This document includes both historical and forward-looking statements. The forward-looking statements are
made within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. We intend such forward-looking statements to be covered by the safe harbor provisions
for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and we are
including this statement for purposes of complying with these safe harbor provisions. We have based these
forward-looking statements on our current expectations and projections about future events, trends and
uncertainties. These forward-looking statements are not guarantees of future performance and are subject to risks,
uncertainties and assumptions, including, among other things, the information discussed below. In making these
statements, we are not undertaking to address or update each factor in future filings or communications regarding
our business or results. Our business is highly complicated, regulated and competitive with many different
factors affecting results.
If the premiums we charge are insufficient to cover the cost of health care services delivered to our
members, or if our estimates of medical claim reserves based upon our estimates of future medical claims are
inadequate, our profitability could decline.
We use a significant portion of our revenues to pay the costs of health care services delivered to our
members. These costs include claims payments, capitation payments, allocations of some centralized expenses
and various other costs incurred to provide health insurance coverage to our members. These costs also include
estimates of future payments to hospitals and others for medical care provided to our members. Generally,
premiums in the health care business are fixed for one-year periods. Accordingly, costs we incur in excess of our
medical cost projections generally are not recovered in the contract year through higher premiums. We estimate
the costs of our future medical claims and other expenses using actuarial methods and assumptions based upon
claim payment patterns, medical inflation, historical developments, including claim inventory levels and claim
receipt patterns, and other relevant factors. We also record medical claims reserves for future payments. We
continually review estimates of future payments relating to medical claims costs for services incurred in the
current and prior periods and make necessary adjustments to our reserves. However, increases in the use or cost
of services by our members, competition, government regulations and many other factors may and often do cause
actual health care costs to exceed what was estimated and reflected in premiums.
These factors may include:
• increased use of medical facilities and services, including prescription drugs;
• increased cost of such services;
• the Company’s membership mix;
• termination of capitation arrangements resulting in the transfer of membership to fee-for-service
arrangements;
• changes or reductions of our utilization management functions such as preauthorization of services,
concurrent review or requirements for physician referrals;
• catastrophes, including acts of terrorism or epidemics;
• the introduction of new or costly treatments, including new technologies;
