Fitch Rates CJSC ACE Insurance National IFS 'AA+(rus)': Outlook Stable

Fitch Ratings has today assigned CJSC ACE Insurance Company ("ACE
Russia") a National IFS rating of 'AA+(rus)'. The Outlook on the IFS
rating is Stable.

Responding to the announcement, Andrew Kendrick, Chairman and CEO,
ACE European Group (NYSE:ACE), said,

"ACE Russia commenced operations in April 2005 and is already
making good progress in the Russian market, with principal focus being
on technical lines, construction business and Accident and Health.
Russia represents one of a number of exciting new opportunities for
ACE in Europe as we continue our geographical expansion. The Russian
economy is powering ahead, driven predominantly by exports of energy
and other natural resources and there is undoubtedly significant
future potential. ACE's commitment to the Russian market was further
reinforced by the decision earlier in 2006 to acquire a 15%
shareholding in the specialist reinsurer Russian Re. Today's
announcement by Fitch is good news for both ACE Russia and its
customers."
