UNITEDHEALTHCARE MERGES WITH OXFORD HEALTH PLANS

We are pleased to announce that the merger between UnitedHealthcare and Oxford Health Plans has been formally completed, uniting two highly complementary organizations focused on creating more choice and access in our markets. UnitedHealthcare’s tri-state operations will be combined with those of Oxford Health Plans under the leadership of Chuck Berg.

Our plan is to blend the best of both companies, creating numerous benefits for our customers, brokers, physicians, hospitals and all of the people we jointly serve. Oxford Health Plans offers consumers access to a broad network of quality health care physicians and providers in the tri-state region, while UnitedHealth Group brings a strong national network. This combination strengthens the offerings and capabilities available to customers of both companies, enabling greater flexibility, choice, and access to the health care system. The blending of these two companies will give us these advantages:

·  A comprehensive portfolio of fully insured, self-insured and ancillary products in the tri-state area

·  Increased flexibility and broader access to quality health care

·  Deep regional health care relationships enhanced by the strength of an extensive national network of services

·  Improved efficiency through technology and a shared focus on affordability

·  Service tailored to the unique needs of all market segments

Our relationship with you is of paramount importance, and we recognize that you may have questions about product offerings, plan designs, network integration, commissions and other matters. Now that the transaction is closed, we are able, for the first time, to share previously restricted information that is required to make detailed decisions about the combination of the two companies.

As we develop our detailed plans for the combined organization, we will involve representatives from the brokerage community in the decision-making process. Please be assured that expediting the integration of our sales and customer service forces and addressing product, network and sales questions are absolute priorities. Some of the solutions will be obvious, while others will take more time to thoroughly assess and resolve. You have our commitment that we will provide regular updates on the progress we are making.

In the near future we will hold several teleconferences and post additional information on the broker section of UnitedHealthcare’s and Oxford Health Plans web sites. You will receive your invitation to participate in these teleconferences shortly. We will also hold broker seminars in the next 60-90 days to update you on our progress and provide many of the details of the integration. In the interim, you should continue to work with your existing representatives through your normal channels. It is business as usual.

Combining the best local health plans with the best regional and national networks meets an important need in the tri-state marketplace. We look forward to working with you to maximize this shared opportunity. If you have any questions, please contact your representative.
