A reduction or less than expected increase in Medicare and Medicaid program funding and/or our failure to retain and acquire Medicare, Medicaid and State Medicaid Children’s Health Insurance Programs (SCHIP) enrollees could adversely affect our revenues and financial results.

We participate as a payer in Medicare Advantage, Medicare Part D, and various Medicaid and SCHIP programs and receive revenues from the Medicare, Medicaid and SCHIP programs to provide benefits under these programs. Our participation in these programs is through bids that are submitted periodically. Revenues for these programs are dependent upon periodic funding from the federal government or applicable state governments and allocation of the funding through various payment mechanisms. Funding for these programs is dependent upon

many factors outside of our control, including general economic conditions at the federal or applicable state level and general political issues and priorities. A reduction or less than expected increase in government funding for these programs or change in allocation methodologies may adversely affect our revenues and financial results.

Our ability to retain and acquire Medicare, Medicaid and SCHIP enrollees is impacted by bids and plan designs submitted by us and our competitors. Under the Medicaid Managed Care program, state Medicaid agencies are periodically required by federal law to seek bids from eligible health plans to continue their participation in the acute care Medicaid health programs. If we are not successful in obtaining renewals of state Medicaid Managed Care contracts, we risk losing the members that were enrolled in those Medicaid plans. Under the Medicare Part D program, to qualify for automatic enrollment of low income members, our bids must result in an enrollee premium below a threshold, which is set by the government after our bids are submitted. If the enrollee premium is not below the government threshold, we risk losing the members who were auto-assigned to us and we will not have additional members auto-assigned to us. For example, we lost approximately 650,000 of our auto-enrolled low-income subsidy members in 2008 because our bids exceeded thresholds set by the government. In general, our bids are based upon certain assumptions regarding enrollment, utilization, medical costs, and other factors. In the event any of these assumptions are materially incorrect or our competitors’ bids and positioning are different than anticipated, either as a result of unforeseen changes to the Medicare program or otherwise, our financial results could be materially affected.
