Item 2.02.    Results of Operations and Financial Condition.

On November 1, 2005, RenaissanceRe Holdings Ltd. (the "Company") issued a press release (the "Press Release") announcing the Company's preliminary results for the quarter ended September 30, 2005. 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 to the Securities and Exchange Commission (the "SEC") pursuant to Item 2.02 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 loss attributable to common shareholders" of $327.3 million in the third quarter of 2005 (as compared with $363.5 million in the third quarter of 2004). The Company has also included in the Press Release "net operating loss per common share" of $4.63 during the third quarter of 2005 (as compared with $5.19 per common share during the third quarter of 2004) and of $1.45 for the nine-month period ended September 30, 2005 (as compared with $1.13 for the nine-month period ended September 30, 2004). Each of these measures is a non-GAAP financial measure.

The Company uses "operating loss" as a measure to evaluate the underlying fundamentals of its operations and believes it to be a useful measure of its corporate performance. "Operating loss," as used in the Press Release and herein, differs from "net loss," 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 loss attributable to common shareholders" during the third quarter of 2005 was $322.1 million (as compared with $348.5 million during the third quarter of 2004) and was $105.8 million for the nine-month period ended September 30, 2005 (as compared with $58.4 million for the nine-month period ended September 30, 2004). In the Press Release, the Company also provides that "net loss per common share" during the third quarter of 2005 was $4.56 (as compared with $4.97 per common share during the third quarter of 2004) and was $1.50 for the nine-month period ended September 30, 2005 (as compared with $0.84 for the nine-month period ended September 30, 2004). In addition to the reasons for this presentation set forth above, the Company's management also believes that presentation of "operating loss" 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 $128.5 million in the third quarter of 2005 (as compared with $104.7 million in the third quarter of 2004) and of $692.7 million for the nine-month period ended September 30, 2005 (as compared with $721.6 million for the nine-month period ended September 30, 2004), which is a non-GAAP financial measure. The principal difference between "total managed catastrophe premium" and "total catastrophe premium," which the Company believes is the most directly comparable GAAP measure, is the inclusion in "total 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 $128.0 million in the third quarter of 2005 (as compared with $98.8 million during the third quarter of 2004)

and was $632.8 million for the nine-month period ended September 30, 2005 (as compared with $651.5 million for the nine-month period ended September 30, 2004).

The Company has also included in the Press Release "operating return on average common equity (annualized)" of (61.2%) for the third quarter of 2005 (as compared with (68.0%) for the third quarter of 2004) and of (6.4%) for the nine-month period ended September 30, 2005 (as compared with (4.9%) for the nine-month period ended September 30, 2004), 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 equity (annualized)" excludes realized gains and losses on investments. In the Press Release, the Company provides that "return on average common equity (annualized)" was (60.2%) in the third quarter of 2005 (as compared with (65.2%) for the third quarter of 2004) and was (6.6%) for the nine-month period ended September 30, 2005 (as compared with (3.6%) for the nine-month period ended September 30, 2004).
