ITEM 12. RESULTS OF OPERATION AND FINANCIAL CONDITION.

     On July 27, 2004, RenaissanceRe Holdings Ltd. (the "Company") issued a
press release (the "Press Release") announcing the Company's preliminary results
for the quarter ended June 30, 2004. A copy of the Press Release is attached
hereto as Exhibit 99.1 to this Form 8-K. This Form 8-K and Exhibit 99.1 hereto
are each being furnished pursuant to Item 12 of Form 8-K and are therefore not
to be considered "filed" with the SEC.

Non-GAAP Financial Measures
---------------------------

     In addition to the GAAP financial measures set forth in the Press Release,
the Company has included certain non-GAAP financial measures in the Press
Release within the meaning of Regulation G. The Company has consistently
provided these financial measurements in previous earnings releases 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
comparison with other companies in the industry. These measures may not,
however, be comparable to similarly titled measures used by companies outside of
the insurance industry, or by other insurers. Investors are cautioned not to
place undue reliance on these non-GAAP measure in assessing the Company's
overall financial performance.

     The Company has included in the Press Release "net operating income
available to common shareholders" of $143.1 million in the second quarter of
2004 (as compared with $130.5 million in the second quarter of 2003) and of
$281.0 million for the six-month period ended June 30, 2004 (as compared with
$260.7 million for the six-month period ended June 30, 2003). The Company

                                       2



has also included in the Press Release "operating income per common share" of
$2.00 during in the second quarter of 2004 (as compared with $1.84 per common
share in the second quarter of 2003, and of $3.92 for the six-month period ended
June 30, 2004 (as compared with $3.68 for the six-month period ended June 30,
2003). Each of these measures is a non-GAAP financial measure.

     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 in the Press Release and
herein, differs from "net income," which the Company believes is the most
directly comparable GAAP measure, by the exclusion of net realized gains and
losses on investments. In the Press Release, the Company provides that "net
income available to common shareholders" was $116.2 million in the second
quarter of 2004 (as compared with $180.2 million in the second quarter of 2003)
and was $286.6 million for the six-month period ended June 30, 2004 (as compared
with $331.5 million for the six-month period ended June 30, 2003). In the Press
Release, the Company also provides that "net income per common share" was $1.62
in the second quarter of 2004 (as compared with $2.54 per common share for the
second quarter of 2003) and was $4.00 for the six-month period ended June 30,
2004 (as compared with $4.68 for the six-month period ended June 30, 2003). In
addition to the reasons for this presentation set forth above, the Company's
management also believes that presentation of "operating income" is useful to
investors because it presents the Company's results of operations without the
variability arising from fluctuations in the Company's investment portfolio,
which is not considered by the Company's management to be a relevant indicator
of business operations.

     The Company has also included in the Press Release "managed catastrophe
premium" of $175.5 million in the second quarter of 2004 (as compared with
$103.8 million in the second quarter of 2003) and of $616.9 million for the
six-month period ended June 30, 2004 (as compared with $568.5 million for the
six-month period ended June 30, 2003), which is a non-GAAP financial measure.
The principal difference between "managed catastrophe premium" and "total
catastrophe premium," which the Company believes is the most directly comparable
GAAP measure, is the inclusion in "managed catastrophe premium" of catastrophe
premium written by Top Layer Reinsurance Ltd., a joint venture which is
accounted for under the equity method of accounting. In the Press Release, the
Company provides that "total catastrophe premium" was $150.3 million in the
second quarter of 2004 (as compared with $80.6 million during the second quarter
of 2003) and was $552.6 million for the six-month period ended June 30, 2004 (as
compared with $496.1 million for the six-month period ended June 30, 2003).

     The Company has also included in the Press Release "summary of income from
joint venture relationships" of $37.9 million in the second quarter of 2004 (as
compared with $31.6 million in the second quarter of 2003) and of $71.7 million
for the six-month period ended June 30, 2004 (as compared with $67.7 million for
the six-month period ended June 30, 2003), which is a non-GAAP financial
measure. The principal differences between "summary of income from joint venture
relationships" and "other income and equity in earnings of unconsolidated
ventures," which the Company believes is the most directly comparable

                                       3


GAAP measure, are that the results of DaVinci Reinsurance Ltd., a joint venture
the financial results of which are consolidated in the Company's financial
statements, are reflected in "summary of income from joint venture
relationships" as if reported under the equity accounting method, and that this
presentation also includes fees earned on certain quota share cessions of
catastrophe business by the Company which are reflected on its income statement
as a reduction of acquisition and operational expenses. In the Press Release,
the Company provides that "other income and equity in earnings of unconsolidated
ventures" was $4.2 million in the second quarter of 2004 (as compared with $7.2
million during the second quarter of 2003) and was $11.9 million for the
six-month period ended June 30, 2004 (as compared with $12.7 million for the
six-month period ended June 30, 2003).

     The Company has also included in the Press Release "operating return on
average common equity (annualized)" of 25.2% for the second quarter of 2004 (as
compared with 30.2% for the second quarter of 2003) and of 25.4% for the
six-month period ended June 30, 2004 (as compared with 31.6% for the six-month
period ended June 30, 2003), which is a non-GAAP financial measure. The
principal difference between "operating return on average common equity
(annualized)" and "return on average common equity (annualized)," which the
Company believes is the most directly comparable GAAP measure, is that
"operating return on average common equity (annualized)" excludes net realized
gains and losses on investments. In the Press Release, the Company provides that
"return on average common equity (annualized)" was 20.5% in the second quarter
of 2004 (as compared with 41.7% for the second quarter of 2003) and was 25.9%
for the six-month period ended June 30, 2004 (as compared with 40.2% for the
six-month period ended June 30, 2003).

     The Press Release also sets forth a revised estimate of "operating earnings
per common share" for 2004 in the range of $6.95 and $7.25 versus a previous
forecast of $6.10 to $6.50, assuming normal loss levels for the balance of 2004.
The forecast of "operating earnings per common share" for 2004 is a non-GAAP
financial measure and excludes realized gains on investments of $5.6 million for
the first six months of 2004 and all potential realized gains and losses on
investments for the final six months of 2004. The Company is unable to forecast
"net income per common share for 2004", which the Company believes is the most
directly comparable GAAP measure, as predictions as to the amount of realized
gains and losses on investments for the final six months of 2004 are dependent
on the performance of the financial markets.
