ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS (a) Not applicable. (b) Not applicable. (c) Exhibits. The following exhibits are filed as part of this report: Exhibit # Description --------- ----------- 99.1* Copy of the Company's press release, issued May 4, 2004. * Exhibit 99.1 is being furnished to the Securities and Exchange Commission (the "SEC") pursuant to Item 12 and is not being filed with the SEC. Therefore, this exhibit is not incorporated by reference in any of the registrant's other SEC filings. ITEM 12. RESULTS OF OPERATION AND FINANCIAL CONDITION. On May 4, 2004, RenaissanceRe Holdings Ltd. (the "Company") issued a press release (the "Press Release") announcing the Company's preliminary results for the quarter ended March 31, 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 $137.8 million in the first quarter of 2004 (as compared with $130.2 million in the first quarter of 2003). The Company has also included in the Press Release "operating income per common share" of $1.93 during the first quarter of 2004 2

(as compared with $1.84 per common share during the first quarter of 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" during the first quarter of 2004 was $170.4 million (as compared with $151.3 million during the first quarter of 2003). In the Press Release, the Company also provides that "net income per common share" during the first quarter of 2004 was $2.38 (as compared with $2.14 per common share during the first quarter of 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 $441.4 million in the first quarter of 2004 (as compared with $464.7 million in the first quarter of 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 "manual 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 $402.3 million in the first quarter of 2004 (as compared with $415.5 million during the first quarter of 2003). The Company has also included in the Press Release "summary of income from joint venture relationships" of $33.7 million in the first quarter of 2004 (as compared with $36.1 million in the first quarter of 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 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 $7.6 million in the first quarter of 2004 (as compared with $5.5 million during the first quarter of 2003). The Company has also included in the Press Release "operating return on average common equity (annualized)" of 25.5% for the first quarter of 2004 (as compared with 33.3% for the first quarter of 2003), which is a non-GAAP financial measure. 3

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 31.5% in the first quarter of 2004 (as compared with 38.7% for the first quarter of 2003). 4

EXHIBIT 99.1 [GRAPHIC OMITTED] RENAISSANCERE REPORTS OPERATING INCOME OF $137.8 MILLION FOR 2004 FIRST QUARTER; OPERATING EPS OF $1.93 PER COMMON SHARE FOR THE FIRST QUARTER OF 2004 VS. $1.84 FOR THE FIRST QUARTER OF 2003 $170.4 MILLION NET INCOME FOR THE FIRST QUARTER OF 2004; EPS OF $2.38 FOR THE FIRST QUARTER OF 2004 VS. EPS OF $2.14 FOR THE FIRST QUARTER OF 2003 MANAGED SPECIALTY REINSURANCE PREMIUM GROWS TO $258.0 MILLION COMPARED TO $205.8 MILLION IN 2003 INDIVIDUAL RISK SEGMENT PREMIUM GROWS TO $119.9 MILLION FOR THE FIRST QUARTER OF 2004 COMPARED TO $63.8 MILLION IN 2003 ACHIEVES FIRST QUARTER 2004 ANNUALIZED OPERATING RETURN ON EQUITY OF 25.5% PEMBROKE, BERMUDA, MAY 4, 2004 -- RenaissanceRe Holdings Ltd. (NYSE: RNR) today reported $137.8 million in first quarter net operating income available to common shareholders, compared to $130.2 million in the first quarter of 2003. Operating income excludes realized investment gains of $32.5 million and $21.1 million in the first quarters of 2004 and 2003, respectively. Operating income per common share grew to $1.93 in the first quarter of 2004, from $1.84 per common share in the first quarter of 2003. Net income available to common shareholders rose 13% to $170.4 million or $2.38 per common share in the quarter, from $151.3 million or $2.14 per common share for the same quarter of 2003. James N. Stanard, Chairman and CEO, commented: "This quarter demonstrates the increasing diversification of RenaissanceRe's business mix. Strong first quarter growth in Individual Risk and specialty reinsurance positions us well to meet our targeted 2004 growth rates in these lines of 30% and 20%, respectively, and more than offset the 5% decline in gross managed cat premium, which was in line with our expectations. We also benefited from another quarter of light catastrophes, and continued to deliver strong returns on equity and growth in book value per share." FIRST QUARTER 2004 RESULTS: - --------------------------- PREMIUMS - -------- Gross premiums written for the first quarter of 2004 were $780.3 million, compared to $685.2 million for the same quarter of 2003. Gross premiums written include $660.4 million in gross premiums written for the Company's Reinsurance segment in the first quarter of 2004, compared to $621.3 million for the same quarter of 2003; and $119.9 million in gross premiums written for the Company's Individual Risk segment in the first quarter of 2004, compared to $63.8 million for the same quarter of 2003. Net premiums written for the first quarter of 2004 were $706.0 million, versus $590.4 million for the same quarter of 2003. Net premiums written include $596.2 million in net premiums written for the Company's Reinsurance segment in the first quarter of 2004, compared to $557.9 million for the same quarter of 2003; and $109.8 million in net premiums written for the Company's Individual Risk segment in the first quarter of 2004, compared to $32.5 million for the same quarter of 2003. 1

Net premiums earned for the first quarter of 2004 were $309.6 million, compared to $263.5 million for the same quarter of 2003. Net premiums earned include $208.8 million in net premiums earned for the Company's Reinsurance segment in the first quarter of 2004, compared to $200.4 million for the same quarter of 2003; and $100.8 million in net premiums earned for the Company's Individual Risk segment in the first quarter of 2004, compared to $63.0 million for the same quarter of 2003. Premiums for the first quarter of 2004 include $130.8 million of gross written premiums and $128.7 million of net written premiums and $47.0 million of net premiums earned by the Company's consolidated joint venture, DaVinci Re during the first quarter of 2004, compared to $126.5 million of gross and net written premiums and $49.1 million of net premiums earned by DaVinci Re during the first quarter of 2003. Total managed cat premiums written, representing gross catastrophe premiums written by Renaissance Reinsurance and by related joint ventures, were $441.4 million for the first quarter of 2004, compared to $464.7 million for the same quarter of 2003, representing a decrease of approximately 5%, which was in line with management's expectations. See the attached supplemental financial data for additional information regarding managed premiums. JOINT VENTURE INCOME - -------------------- During the quarter, the income from the DaVinci joint venture and other fee income was $33.7 million, compared to $36.1 million during the first quarter of 2003. Of this, $16.9 million reflects fees and profit commissions, compared to $20.2 million in the first quarter of 2003, and $16.8 million reflects equity in earnings of unconsolidated ventures and DaVinci, versus $17.7 million in the comparable quarter of 2003. Also during the quarter, the Company consummated its $119.7 million investment in ChannelRe Holdings Ltd. This investment has been reflected in the balance sheet under the caption "investments in other ventures, under the equity method", which also includes our investment in Top Layer Reinsurance Ltd. The earnings on our investment in ChannelRe Holdings Ltd. will be recorded one quarter in arrears, therefore the first quarterly earnings impact of this investment will be recorded in our consolidated statements of income in the second quarter. UNDERWRITING RATIOS, RESERVE DEVELOPMENT: - ----------------------------------------- For the first quarter of 2004, the Company generated a combined ratio of 59.0%, a loss ratio of 36.2% and an expense ratio of 22.8%, compared to a combined ratio, loss ratio and expense ratio of 53.0%, 31.4% and 21.6% for the first quarter of 2003, respectively. The increase in the loss and expense ratios primarily relates to the increased scale of the Company's Individual Risk segment, which typically generates higher loss and expense ratios than the Reinsurance segment. For the quarter, the Company's Reinsurance segment generated a loss ratio of 28.0% and an expense ratio of 14.3%, compared to 28.4% and 17.4%, respectively, during the first quarter of 2003. The expense ratio includes the benefit of a reversal of an accrual for incentive compensation expense and in future periods management expects this expense ratio to return to higher levels. For the quarter, the Company's Individual Risk segment generated a loss ratio of 53.2% and an expense ratio of 40.2%, compared to 41.1% and 35.1%, respectively during the first quarter of 2003. During the quarter, the Company recorded favorable development on prior year reserves of $21.7 million or a benefit of 7.0 points to the Company's quarterly loss ratio. The Company's Reinsurance segment contributed $16.9 million and the Individual Risk segment contributed $4.8 million of favorable development on prior year reserves. Net paid losses for the quarter were $59.4 million. See the attached supplemental financial data for additional information regarding claims and claim expenses incurred and loss ratios by segment. INVESTMENTS: - ------------ Net investment income for the first quarter of 2004 was $35.1 million, compared to $31.4 million for the same quarter in 2003.

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 measure, 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 it more accurately measures and predicts the Company's results of operations by removing the variability arising from fluctuations in the registrant'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. The following is a reconciliation of 1) net income available to common shareholders to operating income; 2) net income available to common shareholders per common share to operating income per common share; and 3) return on average common equity to operating return on average common equity: QUARTERS ENDED -------------------------------------------- (In thousands of U.S. dollars) MARCH 31, 2004 MARCH 31, 2003 -------------------- ---------------------- Net income available to common shareholders $ 170,354 $ 151,285 Adjustment for net realized gains on investments (32,521) (21,112) -------------------- ---------------------- Operating income $ 137,833 $ 130,173 ==================== ====================== Net income available to common shareholders per common share - diluted $ 2.38 $ 2.14 Adjustment for net realized gains on investments (0.45) (0.30) -------------------- ---------------------- Operating income per common share - diluted $ 1.93 $ 1.84 ==================== ====================== Return on average common equity (annualized) 31.5% 38.7% Adjustment for net realized gains on investments (6.0%) (5.4%) -------------------- ---------------------- Operating return on average common equity (annualized) 25.5% 33.3% ==================== ====================== 8

The Company has also included in this Press Release "managed cat premium". "Managed cat premium" is defined as gross catastrophe premium written by Renaissance Reinsurance and its related joint ventures. "Managed cat 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 our joint venture Top Layer Re, which is accounted for under the equity method of accounting. Refer to supplemental financial data on gross written premiums. The Company has also included in this Press Release "summary of income from joint venture relationships" 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 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. 9
