Item 8.01.             Other Events

On March 21, 2012, Fallon Community Health Plan (“FCHP”) and Magellan Health Services, Inc. (“Magellan”) entered into a Joint Venture Development Agreement and are forming a Joint Venture to apply to participate in a new demonstration program that will provide integrated health care to individuals aged 21 to 64 years who are dually-eligible for Medicare and Medicaid in Massachusetts (the “Demonstration”).

To most appropriately respond to this opportunity, FCHP and Magellan will develop an integrated care organization (“ICO”) to be called “Fallon Total Care”. The ICO will bring together Magellan’s clinical expertise in behavioral health services and FCHP’s capabilities and experience in managing the physical health care needs of dual-eligible individuals.  There is no assurance that Massachusetts will proceed with the Demonstration or that Fallon Total Care will ultimately be selected as a participating ICO for the Demonstration. The joint venture will be structured with FCHP owning 51 percent and Magellan owning 49 percent.

Attached and incorporated herein by reference as Exhibit 99.1 is a copy of the press release dated March 22, 2012.
