          RENAISSANCERE HOLDINGS COMMENTS ON HURRICANE KATRINA IMPACT

PEMBROKE, BERMUDA, SEPTEMBER 9, 2005 - RenaissanceRe Holdings Ltd. (NYSE: RNR)
provided today an initial assessment of the impact of Hurricane Katrina on its
financial results.

Due to the extremely limited claims data, as well as potential legal and
regulatory developments related to potential losses, the Company noted that it
is difficult to provide an estimate of the financial impact of this event on the
Company. In looking at a broad range of possible outcomes, the Company estimated
that the net negative impact on its financial results from Hurricane Katrina
will be approximately 1% of the aggregate insurance industry losses arising from
the hurricane.

The estimates for the Company and the industry include losses arising in all
sectors of insurance and reinsurance, including residential property, commercial
property, marine, energy and any other affected classes and coverages, including
business interruption and privately insured flood. The Company noted that its
estimate is preliminary, and that an assessment of the storm's impact on the
industry, and on the Company, is subject to substantial uncertainty in light of
the unique features of this event.

The Company indicated that, because of the storm, it does not expect to meet its
previously announced earnings guidance for 2005. However, the Company noted that
it expects to be profitable for the full year of 2005, assuming no significant
catastrophe loss events for the balance of the year.

James N. Stanard, the Company's Chairman and CEO, commented: "We extend our
sympathies to the victims of this hurricane, and recognize its enormous human
impact. As we have demonstrated in prior catastrophes, we stand ready to serve
our customers in responding to the losses and promptly paying claims."
