The consolidated UnitedHealth Group has a very strong business profile, strong earnings and cash flow, and very strong financial flexibility. We have revised our outlook on all of the UnitedHealth companies to positive from stable. In addition, we have affirmed the 'A-/A-2' counterparty credit rating on the holding company and the 'A+' counterparty credit and financial strength ratings on the core operating companies. We have also raised to 'A+' from 'A' the counterparty credit and financial strength ratings on the operating companies that we now consider to be core to the enterprise rather than strategically important.
