                    VS. $0.76 FOR THE FIRST QUARTER OF 2005.

  $179.0 MILLION OF NET INCOME FOR THE FIRST QUARTER OF 2006; $2.49 NET INCOME
            PER COMMON SHARE VS. $0.62 FOR THE FIRST QUARTER OF 2005.

PEMBROKE, BERMUDA, MAY 2, 2006 -- RenaissanceRe Holdings Ltd. (NYSE: RNR) today
reported $195.7 million in first quarter operating income available to common
shareholders compared to $54.5 million in the first quarter of 2005. Operating
income excludes net realized investment losses of $16.8 million and $10.2
million in the first quarters of 2006 and 2005, respectively. Operating income
per common share was $2.73 in the first quarter of 2006, compared to $0.76 in
the first quarter of 2005. Net income available to common shareholders was
$179.0 million or $2.49 per common share in the quarter, compared to net income
available to common shareholders of $44.3 million or $0.62 per common share for
the same quarter of 2005.

Neill A. Currie, CEO, commented, "We had a strong first quarter with over 8%
growth in our book value per common share. Our first quarter results benefited
from light catastrophe losses and lower than expected reported claims on prior
year reserves within our Reinsurance segment, but also demonstrate the ongoing
strength of the RenaissanceRe business and franchise."

Mr. Currie continued, "Given improving pricing and terms for catastrophe
reinsurance, we grew our managed catastrophe reinsurance premium by 23% in the
quarter; for the year, we continue to expect growth of over 15%, but recognize
that there is substantial uncertainty - and potential upside - depending largely
upon the ultimate magnitude of our opportunities in Florida. Conversely, we are
seeing fewer attractive opportunities within specialty reinsurance than we had
hoped. Our specialty premium declined by 43% which is more pronounced than our
2006 guidance of a 35% decline, although our specialty premium can fluctuate
from quarter to quarter. Our Individual Risk segment is on track with our
expectations of 15% top line growth for the year and generated solid
underwriting income for the quarter."

Mr. Currie added, "Overall, we are pleased with the performance for the quarter.
The team is energized, and we are well positioned to participate in the
hardening property catastrophe market we now see for this year."

UNDERWRITING RATIOS, RESERVE DEVELOPMENT
- ----------------------------------------

For the first quarter of 2006, the Company generated a combined ratio of 53.7%,
a loss ratio of 28.2% and an underwriting expense ratio of 25.5%, compared to a
combined ratio, loss ratio and underwriting expense ratio of 90.2%, 66.9% and

million or a decrease of 11.9 percentage points in the Company's quarterly loss
ratio. Net paid losses for the quarter were $247.0 million compared to $159.5
million in the first quarter of 2005.

Reinsurance Segment

The Company's Reinsurance segment generated a loss ratio of 17.2% and an
underwriting expense ratio of 19.2% for the first quarter of 2006, compared to a
loss ratio and underwriting expense ratio of 70.8% and 17.4%, respectively, for

2005 and added 30.3 percentage points to the 2005 first quarter loss ratio.
During the first quarter of 2006, the Company's Reinsurance segment contributed
$39.0 million of favorable development on prior year reserves or a decrease of
18.3 percentage points to the Company's quarterly loss ratio. The favorable
development was driven by lower than expected reported claims on prior year
reserves in the Company's specialty reinsurance unit.

underwriting expense ratio of 35.2% for the first quarter of 2006, compared to a

EQUITY IN EARNINGS OF OTHER VENTURES
- ------------------------------------

Equity in earnings of other ventures generated $6.6 million in income in the
first quarter of 2006 compared to $7.6 million in income in the first quarter of
2005. In 2006 this included the Company's equity in the earnings of its


                                       2


investments in Top Layer Reinsurance Ltd. ("Top Layer Re"), ChannelRe Holdings
Ltd. ("ChannelRe") and Tower Hill Capital Holdings Inc. ("Tower Hill"). In 2005,
it included the Company's equity in the earnings of its interests in Top Layer
Re and ChannelRe. The decrease was principally due to a $0.7 million and a $0.4
million reduction of equity in earnings from Top Layer Re and ChannelRe,
respectively.

OTHER INCOME
- ------------

During the first quarter of 2006 the Company recognized a $1.7 million net loss
on fees and other items compared to a $3.5 million net loss in the first quarter
of 2005. Fee income remained stable at $1.0 million in the first quarter of 2006
compared to the first quarter of 2005. Other items generated a loss of $2.7
million in the first quarter of 2006, principally driven by a $3.3 million
mark-to-market loss on the Company's warrant to purchase 2.5 million shares of
Platinum Underwriters Holding Ltd. ("Platinum") common stock, compared with a
loss of $4.5 million in the first quarter of 2005, which included a $2.1 million
mark-to-market loss on the Platinum warrant and a $2.0 million mark-to-market
loss on the Company's short position in credit derivatives.

NET INVESTMENT INCOME AND NET REALIZED GAINS AND LOSSES ON INVESTMENTS
- ----------------------------------------------------------------------

Net investment income for the first quarter of 2006 was $80.4 million, compared
to $51.2 million for the same quarter in 2005 reflecting a higher yield on our
portfolio of fixed maturity investments available for sale and short term
investments, partially offset by our decreased allocation to higher yield fixed
maturity investments. Other investments, which include the Company's hedge fund
and private equity investments, generated $26.7 million of net investment income
in the first quarter of 2006 compared with $18.7 million in the first quarter of
2005.

During the first quarter of 2006, the Company recorded $16.8 million of net
realized losses compared to $10.2 million in the first quarter of 2005. Included
in net realized losses are other than temporary impairment charges of $18.8
million and $2.8 million in the first quarter of 2006 and 2005, respectively,
with respect to the Company's portfolio of fixed maturity investments available
for sale.

OTHER ITEMS
- -----------

Corporate expenses of $5.7 million were incurred during the first quarter of
2006 compared to $11.3 million in the first quarter of 2005. The difference in
such expenses principally relates to the difference in costs incurred related to
the Company's internal review and the ongoing investigations into the Company
and certain of its present and former executive officers by governmental
authorities, which totaled $1.2 million in the first quarter of 2006 compared to
$7.4 million in the first quarter of 2005.

The Company's cash flows from operations were $146.1 million for the first
quarter of 2006, compared to $253.2 million for the first quarter of 2005.

Shareholders' equity attributable to common shareholders was $1.9 billion at
March 31, 2006, compared to $1.8 billion at December 31, 2005. Book value per
common share at March 31, 2006 was $26.65, compared to $24.52 per common share
at December 31, 2005.

COMMENTS ON REGULATION G

In addition to the GAAP financial measures set forth in this Press Release, the
Company has included certain non-GAAP financial measures in this Press Release
within the meaning of Regulation G. The Company has consistently provided these
financial measurements in previous investor communications and the Company's
management believes that these measurements are important to investors and other
interested persons, and that investors and such other persons benefit from
having a consistent basis for comparison between quarters and for the comparison
with other companies within the industry. These measures may not, however, be
comparable to similarly titled measures used by companies outside of the
insurance industry. Investors are cautioned not to place undue reliance on these
non-GAAP measures in assessing the Company's overall financial performance.

The Company uses "operating income" as a measure to evaluate the underlying
fundamentals of its operations and believes it to be a useful measure of its
corporate performance. "Operating income" as used herein differs from "net
income available to common shareholders", which the Company believes is the most
directly comparable GAAP measures, by the exclusion of net realized gains and
losses on investments. In addition, the Company's management believes that
"operating income" is useful to investors because they more accurately measure
and predict the Company's results of operations by removing the variability
arising from fluctuations in the Company's investment portfolio, which is not
considered by management to be a relevant indicator of business operations. The
Company also uses "operating income" to calculate "operating income per common
share" and "operating return on average common equity (annualized)". The
following is a reconciliation of 1) net income available to common shareholders
to operating income available to common shareholders; 2) net income available to
common shareholders per common share to operating income available to common
shareholders per common share; and 3) return on average common equity
(annualized) to operating return on average common equity (annualized):

The Company has also included in this Press Release "managed catastrophe
premium". "Managed catastrophe premium" is defined as gross catastrophe premium
written by Renaissance Reinsurance and its related joint ventures. "Managed
catastrophe premium" differs from total catastrophe premium, which the Company
believes is the most directly comparable GAAP measure, due to the inclusion of
catastrophe premium written on behalf of the Company's joint venture Top Layer
Re, which is accounted for under the equity method of accounting. The Company's
management believes "managed catastrophe premium" is useful to investors and
other interested parties because it provides a measure of total catastrophe
reinsurance premium assumed by the Company through its consolidated subsidiaries
and related joint ventures.
