OLDWICK, N.J.--(BUSINESS WIRE)-- A.M. Best Co. has commented that the financial strength rating of A+ (Superior) and issuer credit ratings (ICR) of "aa-" of PartnerRe Group (PartnerRe) (Hamilton, Bermuda) and its members are unchanged. Concurrently, A.M. Best has commented that the ICR of "a-" and debt ratings of PartnerRe's parent, PartnerRe Ltd. (Hamilton, Bermuda) [NYSE: PRE] also are unchanged by the proposed transaction following PRE's announcement that it plans to acquire PARIS RE Holdings Limited (Paris Re) in an all stock transaction. The outlook for all ratings is stable.

The transaction is valued at approximately $2.0 billion. The consideration will be the exchange of 0.3 of PartnerRe shares for each Paris Re share outstanding after the expected dividend distribution of approximately $ 310 million. The exchange offer will be structured in two steps. The first step, expected to be completed during the fourth quarter of 2009, entails PRE purchasing a majority ownership in Paris Re in a stock-for-stock exchange for the private equity investor's approximately 60% stake in Paris Re, gaining board control. The second step, expected to be completed in the first quarter of 2010, entails an exchange offering for the remainder of Paris Re stock held by minority shareholders. The transaction is subject to customary regulatory and shareholder approvals.

A.M. Best believes that this transaction will further deepen PartnerRe's geographic scope and operating scale. Paris Re maintains a strong balance sheet with the majority of its invested asset base held in fixed income securities of solid credit quality. Paris Re's loss reserves prior to accident year 2006 are guaranteed by its former parent, AXA S.A., which somewhat mitigates the typical risks of acquiring an insurance company's liabilities. A.M. Best does believe that there is integration, operational and treaty overlap risks associated with this transaction; however, given the relative size of Paris Re, these risks should be manageable.


The ratings reflect PartnerRe's excellent business profile, strong risk-adjusted capitalization and strong enterprise risk management practices. PartnerRe is a global provider of multi-line reinsurance, and its competitive position benefits from diversification on both a geographic and product lines basis.
