Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

The Company is providing an update on the status of its efforts to obtain full reimbursement of the Affordable Care Act (ACA) annual fee, including a gross-up payment for the associated tax effects. The table attached hereto and furnished as Exhibit 99.1 summarizes the current status of our efforts to obtain contractual commitments to full reimbursement from the state Medicaid agencies in which we operate our health plans.

Since our Investor Day Conference on February 13, 2014, when we last provided a status update, and as reflected in the Comments column of the attached table, there have been further developments in the states of Ohio, California, New Mexico, Illinois, and Florida. We currently expect to be able to recognize revenue for the reimbursement of the tax, plus a gross up, in the states of Washington and Wisconsin during the first quarter of 2014. With regard to all other states, we remain uncertain as to when we will be able to recognize revenue for the reimbursement of the ACA annual fee and associated tax effects. While we continue to expect that we will ultimately be reimbursed for the ACA annual fee and the associated tax effects, the current lack of contractual commitments from the majority of states in which we operate our health plans could have a material adverse effect on our first quarter operating results.

The information in this Form 8-K current report and the exhibits attached hereto shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, except as expressly set forth by specific reference in such a filing.

“Safe Harbor” Statement under the Private Securities Litigation Reform Act of 1995: This report contains “forward-looking statements” regarding the status of the Company’s efforts to obtain full reimbursement of the ACA annual fee, including a gross-up payment for the associated tax effects. All of the Company’s forward-looking statements are based on our current expectations and assumptions that are subject to numerous known and unknown risks, uncertainties, and other factors that could cause actual results to differ materially. Given these risks and uncertainties, we can give no assurances that our forward-looking statements will prove to be accurate, or that any results or events projected or contemplated by our forward-looking statements will in fact occur, and we caution investors not to place undue reliance on these statements. A discussion of the risk factors facing our Company can be found under Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2013, and in our other reports and filings with the Securities and Exchange Commission and available on its website at www.sec.gov. The Company disclaims any intent or obligation to update any forward-looking statement to conform the statement to actual results or changes in the Company’s expectations.
