ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

         On February 23, 2005, RenaissanceRe Holdings Ltd. (the "Company")
issued a press release (the "Press Release") announcing the Company's
preliminary results for the quarter and year ended December 31, 2004. A copy of
the Press Release is attached hereto as Exhibit 99.1 to this Form 8-K. The
portion of this Form 8-K comprised of this Item 2.02 and Exhibit 99.1 are each
being furnished to the Securities and Exchange Commission (the "SEC") and are
therefore not "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 $188.6 million in the fourth quarter of
2004 (as compared with $152.1 million in the fourth quarter of 2003) and $109.7
million for the year ended December 31, 2004 (as compared with $525.5 million
for the year ended December 31, 2003). The Company has also included in the
Press Release "operating earnings per common share" of $2.62 during the fourth
quarter of 2004 (as compared with $2.14 per common share during the fourth
quarter of 2003) and $1.53 per common share for the year ended December 31, 2004
(as compared with $7.40 per common share for the year ended December 31, 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" differs from "net income,"
which the Company believes is the most directly comparable GAAP measure, only by
the exclusion of realized gains and losses on investments. In the Press Release,
the Company provides that "net income available to common shareholders" during
the fourth quarter of 2004 was $191.5 million (as compared with $160.7 million
during the fourth quarter of 2003) and $133.1 million for the year ended
December 31, 2004 (as compared with $606.0 million for the year ended December
31, 2003). In the Press Release, the Company also provides that "net income per
common share" during the fourth quarter of 2004 was $2.66 (as compared with
$2.26 per common share during the fourth quarter of 2003) and $1.85 per common
share for the 

                                       -2-


year ended December 31, 2004 (as compared with $8.53 per common share for the
year ended December 31, 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
realized investment gains and losses from 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 "total managed
catastrophe premium" of $31.8 million in the fourth quarter of 2004 (as compared
with $42.6 million in the fourth quarter of 2003) and of $753.4 million for the
year ended December 31, 2004 (as compared with $720.4 million for the year ended
December 31, 2003), which is a non-GAAP financial measure. The principal
difference between "total managed cat premium" and "total catastrophe premium,"
which the Company believes is the most directly comparable GAAP measure, is the
inclusion in "total managed cat 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 $31.7 million in the fourth quarter of 2004 (as
compared with $40.0 million during the fourth quarter of 2003) and was $683.2
million for the year ended December 31, 2004 (as compared with $643.7 million
for the year ended December 31, 2003).

         The Company has also included in the Press Release "operating return on
average common equity (annualized)" of 36.7% for the fourth quarter of 2004 (as
compared with 30.3% for the fourth quarter of 2003) and 5.1% for the year ended
December 31, 2004 (as compared with 29.3% for the year ended December 31, 2003),
which is a non-GAAP financial measure. The principal differences 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, are that "operating return on average equity
(annualized)" excludes realized gains and losses on investments. In the Press
Release, the Company provides that "return on average common equity
(annualized)" was 37.2% in the fourth quarter of 2004 (as compared with 32.0%
for the fourth quarter of 2003) and was 6.2% for the year ended December 31,
2004 (as compared with 33.8% for the year ended December 31, 2003).

ITEM 4.02. NON-RELIANCE ON PREVIOUSLY ISSUED FINANCIAL STATEMENTS OR A RELATED
AUDIT REPORT OR COMPLETED INTERIM REVIEW.

(a) The Company announced on February 22, 2005 that it is planning to restate
its financial statements for the years ended December 31, 2001, 2002 and 2003 to
correct accounting errors associated with reinsurance ceded by the Company. The
net effect of these corrections is to increase 2001 net income by $20.6 million,
to decrease 2002 net income by $21.9 million, and to increase 2003 net income by
$1.3 million. The amounts reflect: (1) the timing of the recognition of
reinsurance recoverables (with the impact of increasing net income by $26.4
million in 2001; decreasing net income by $25 million in 2002; and decreasing
net income by $1.4 million in 2003), and (2) the timing of premium ceded on
multi-year contracts (with the impact of decreasing net income by $5.8 million
in 

                                      -3-


2001; increasing net income by $3.1 million in 2002; and increasing net income
by $2.7 million in 2003). The corrections have no effect on the most recently
issued balance sheet of the Company, dated September 30, 2004.

In addition, the Company noted that it had discovered an error in the timing of
the recognition of premium on multi-year ceded reinsurance contracts for the
first three quarters of 2004. In the Company's final 2004 presentation, this
premium will be restated resulting in a decrease of $1.5 million in first
quarter net income, an increase of $5.0 million in second quarter net income and
an increase of $9.0 million in third quarter net income, as compared with the
previously released results. These changes will result in an increase of $12.5
million to the shareholders' equity of the Company as of September 30, 2004.

The accounting errors noted above were discovered in connection with a review
initiated by the Company, which is ongoing. It is possible that such review
could delay the issuance of the Company's audited financial results.

The Company's press release announcing these restatements is attached as Exhibit
99.2 hereto and incorporated herein by reference.

The Company has discussed with Ernst & Young, the Company's independent
accountant, the matters disclosed in this Current Report on Form 8-K pursuant to
this Item 4.02(a).
