OREANDA-NEWS. December 16, 2015. Fitch Ratings has maintained the ratings of Aetna Inc. (Aetna) on Rating Watch Negative following a periodic review of the company's operating performance and financial profile. The ratings were placed on Rating Watch on July 7, 2015, following the company's announcement that it had reached an agreement to acquire Humana Inc. (Humana) in a cash and stock transaction valued at approximately \\$37 billion. A full list of rating actions follows at the end of this release.

KEY RATING DRIVERS
The Rating Watch Negative status of Aetna's ratings reflects expected significant deterioration in the company's financial leverage metrics following the pending close of its acquisition of Humana, as well as potential operational and/or earnings disruptions that could arise as these two very large and complex organizations are integrated. Assuming the acquisition and its financing are completed as currently envisioned, upon close of the acquisition, Fitch expects to downgrade Aetna's ratings by one notch.

At close of the acquisition, Fitch expects Aetna's financial leverage to be approximately 46%, and debt to EBITDA to be in excess of 3.0x due to the debt being issued to fund the cash portion of the purchase price. Fitch does not anticipate that Aetna's financial leverage metrics will return to a level considered appropriate for its current rating category within a 12 to 24 month time horizon normally associated with a Rating Outlook. Given Aetna's size and business profile, these metrics at its current rating would be a run-rate debt to EBITDA ratio approximating 1.8x and financial leverage of 30%-35%.

The ratings of Humana have also historically reflected Fitch's view that Medicare Advantage (MA) enrollment generally supports lower ratings relative to employer group and individual enrollment due to the U.S. government's large role in the MA market and the suppressive effect this role has in terms of margins and capital formation. As a large portion of Humana's revenue is associated with MA business, Aetna's exposure to this business will increase significantly at close of the transaction.

Aetna's ratings reflect the organization's major market position and significant size and scale, strong historical profitability and interest coverage, and generally solid balance sheet characteristics. Fitch views the combination of Aetna and Humana as strategically beneficial to both organizations in terms of the application of Aetna's strong performance in commercial risk business to Humana's commercial business, geographic and business diversification, particularly with regard to Humana, as well as stronger provider networks and pharmacy benefit management capabilities.

Fitch's ratings on Aetna also continue to reflect the risks derived from government involvement in health insurance and managed care companies' ongoing business activities. Fitch's long-held concern is that government efforts to advance public policy goals could further adversely affect health insurance and managed care companies' ability to manage their business and hinder their ability to generate cash flow supporting debt obligations.

RATING SENSITIVITIES
At the close of the transaction, Fitch expects to downgrade the ratings of Aetna by one notch, at which time Fitch will establish new rating triggers associated with the combined company's new ratings.
