OREANDA-NEWS. Fitch Ratings has placed UnitedHealth Group Incorporated's (UnitedHealth) 'A' Issuer Default rating and insurance-company subsidiaries' 'AA-' Insurer Financial Strength (IFS) ratings on Rating Watch Negative after UnitedHealth announced a sizeable acquisition to be funded by debt and cash flow from operations. A complete list of rating actions follows at the end of this release.

KEY RATING DRIVERS

The Negative Rating Watch reflects the intention of UnitedHealth to significantly increase financial leverage to fund the newly announced acquisition of Catamaran Corp. Fitch expects UnitedHealth to issue approximately \$13 billion in senior unsecured debt, increasing financial leverage ratios materially beyond Fitch's current downgrade triggers.

Upon issuance of the debt, Fitch estimates the financial leverage ratio will increase to approximately 47% from 35% at yearend 2014 compared to Fitch's 35% trigger. Similarly, Debt-to-EBITDA is estimated to increase to approximately 2.3x from 1.5x at yearend 2014 compared to Fitch's downgrade trigger of 1.9x. EBITDA coverage of interest will decline to an estimated range of 10x - 12x, down from 18x at yearend 2014, but remaining above Fitch's 8x downgrade trigger.

UnitedHealth is forecasting capitalization ratios to return to historical ranges within an 18-24 month time frame. Further, the company has a successful history of sizeable acquisitions and credible forecasts.

Catamaran is a publicly traded provider of pharmacy benefit management (PBM), and the acquisition by UnitedHealth will create the third largest PBM. The Catamaran acquisition will cost \$14.1 billion, including the \$1.2 billion repayment of existing bank debt, and is expected to close by the fourth quarter of this year.

Favorably, the announced acquisition will further increase UnitedHealth's scale and diversity, particularly its sources of unregulated earnings and cash flows. Fitch continues to view UnitedHealth's overall market position within the health insurance and managed care sector as largely unique, in that it enjoys strength across a broad spectrum of products, services, and geographies.

RATING SENSITIVITIES

Key rating triggers that could result in a downgrade include:
--Fitch expects to resolve the Negative Rating Watch upon UnitedHealth's issuance of debt to fund the acquisition. The likely result would be either a continuation of the Negative Rating Watch or single notch downgrade of all ratings. Rating actions will be based on Fitch's evaluation of execution risks associated with the transaction and the company's plan to reduce financial leverage.
--Developments related to healthcare reform that significantly impair UnitedHealth's ability to appropriately price its products, or otherwise severely restrict the company's cash flow could lead to negative rating actions.

Key rating triggers that could result in a return to a Stable Outlook include:
--Debt-to-EBITDA ratio below 1.9x and debt-to-capital ratio below 35%, while maintaining a double-digit EBITDA-to-interest coverage ratio.
