RenaissanceRe Reports Operating Income of $194.7 Million for the Second Quarter of 2007 or $2.69 Per Common Share

Net Income of $183.2 Million for the Second Quarter of 2007 or $2.53 Per Common Share Book Value Per Common Share Grows by 5.9% in the Second Quarter of 2007

PEMBROKE, Bermuda--(BUSINESS WIRE)--

RenaissanceRe Holdings Ltd. (NYSE: RNR) today reported $194.7 million in second quarter operating income available to common shareholders compared to $154.8 million in the second quarter of 2006. Operating income excludes net realized investment losses of $11.6 million and $24.3 million in the second quarters of 2007 and 2006, respectively. Operating income per diluted common share was $2.69 in the second quarter of 2007, compared to $2.15 in the second quarter of 2006. Net income available to common shareholders was $183.2 million or $2.53 per diluted common share in the quarter, compared to net income available to common shareholders of $130.4 million or $1.81 per diluted common share for the same quarter of 2006.

Neill A. Currie, CEO, commented: "We are pleased to report another quarter of strong financial performance with an annualized operating ROE of over 28% and 5.9% growth in book value per share. We generated solid underwriting profits, despite the U.K. floods, achieved strong investment income and participated in the creation of another new fully-collateralized joint venture during the quarter, Starbound II, which helped bring additional capacity to our clients."

Mr. Currie added: "Our focus is on underwriting as much attractive business as possible rather than trying to achieve premium volume targets. Through the first six months, we have written more property catastrophe reinsurance and less individual risk insurance than originally contemplated. I'm very pleased with the in-force portfolio of risks that our team has constructed."

    SECOND QUARTER 2007 RESULTS

    Underwriting Results

Gross premiums written for the second quarter of 2007 were $845.9 million, a $103.3 million increase from the second quarter of 2006. As described in more detail below, the Company generated $133.6 million of underwriting income and had a combined ratio of 62.7% in the second quarter of 2007, compared to $120.0 million of underwriting income and a 72.2% combined ratio in the second quarter of 2006. The Company's underwriting results for the second quarter of 2007 were driven by an attractive market for the Company's core products and strong renewals and signings by the Company's reinsurance operating subsidiaries, including the inception of an assumed portfolio transfer of a personal lines property quota share reinsurance contract representing $75.4 million of gross premiums written within the Company's specialty unit. Offsetting the factors noted above were losses from flooding in the United Kingdom ("U.K.") and a softening market for other products offered by the Company, which resulted in the Company determining not to renew certain business. In addition, the Company experienced $59.1 million of favorable development on prior year reserves in the second quarter of 2007, compared to $11.3 million of favorable development in the second quarter of 2006.

Reinsurance Segment

Gross premiums written for the Company's Reinsurance segment increased $43.9 million to $606.2 million in the second quarter of 2007, compared to $562.3 million in the second quarter of 2006. The increase in gross premiums written was primarily driven by the impact of an assumed portfolio transfer of a personal lines property quota share reinsurance contract which resulted in $75.4 million of gross premiums written in the quarter within the Company's specialty unit. Also included in gross premiums written within the Reinsurance segment is $65.8 million of premium that was written on behalf of a new fully-collateralized joint venture, Starbound Reinsurance II Limited. ("Starbound II"), in return for a profit commission and an expense override. The premium is ceded to this joint venture, and therefore, does not impact the Company's net premiums written.

The Reinsurance segment generated $121.1 million of underwriting income and had a combined ratio of 46.5% in the second quarter of 2007, compared to $129.3 million of underwriting income and a combined ratio of 53.5% in the second quarter of 2006. Included in the Reinsurance segment underwriting results for the second quarter of 2007 are $53.0 million of net claims and claim expenses associated with the flooding that occurred in the U.K. in the second quarter of 2007. The Company currently estimates a net negative impact from this event of $41.4 million. Net negative impact includes the sum of net claims and claims expenses incurred and minority interest. The Reinsurance segment experienced $49.7 million of favorable development on prior year reserves or a decrease of 22.0 percentage points to the Company's Reinsurance segment quarterly loss ratio in the second quarter of 2007, compared to $2.8 million of favorable development or a decrease of 1.0 percentage point to the Reinsurance segment quarterly loss ratio in the second quarter of 2006. The favorable development in the second quarter of 2007 was principally the result of lower than expected claims emergence.

Individual Risk

Gross premiums written for the Company's Individual Risk segment increased $27.6 million to $238.4 million in the second quarter of 2007, compared to $210.8 million in the second quarter of 2006. The increase in gross premiums written was primarily due to an increase in the Company's commercial multi-line premium.

The Individual Risk segment generated $12.5 million of underwriting income and had a combined ratio of 90.7% in the second quarter of 2007, compared to a $9.3 million underwriting loss and a 106.1% combined ratio in the second quarter of 2006. The increase in underwriting income in the second quarter of 2007 compared to the second quarter of 2006 was primarily due to a lower net claims and claim expense ratio and underwriting expense ratio. The Individual Risk segment experienced favorable development of $9.5 million and $8.5 million on prior year reserves in the second quarters of 2007 and 2006, respectively, principally attributable to lower than expected claims emergence.

Starbound II

During the second quarter of 2007, the Company participated in the establishment of a new fully-collateralized joint venture, Starbound II. Similar to Starbound Reinsurance Limited ("Starbound Re") which was established in the second quarter of 2006, this joint venture enabled the Company to write additional property catastrophe excess of loss reinsurance business for the Company's clients that it may not have otherwise written due to portfolio management or other considerations. The premium for this joint venture is reflected in gross and ceded premiums written, and therefore, has no impact on the Company's net premiums written. The underwriting result on this business, net of a profit commission and expense override, accrues to the investors in the joint venture. The limit ceded to this joint venture, including any reinstatable limits, is fully-collateralized by highly-rated short term and fixed maturity investments as well as the premium receivable.

In conjunction with the Starbound II transaction, the Company made a $10.0 million equity investment in Starbound II, representing a 9.8% ownership interest. This equity investment is accounted for under the equity method of accounting.

        $118.1 million, compared to $74.0 million for the same quarter
        in 2006 as a result of strong returns from the Company's hedge
        fund and private equity investments and higher average
        invested assets in the Company's portfolio of fixed maturity
        investments available for sale and short term investments.
        Other investments, which include the Company's hedge fund and
        private equity investments, generated $41.6 million of net

    --  During the second quarter of 2007, the Company incurred $12.1
        million of other than temporary impairment charges on the
        Company's fixed maturity investments available for sale,
        compared to $23.7 million in the second quarter of 2006.

    --  The Company's cash flows from operations were $190.7 million
        for the second quarter of 2007, compared to $237.4 million for
        the second quarter of 2006.

    PREMIUM FORECASTS

The Company is revising its annual premium forecasts. Previously, the Company was forecasting a 15% decline in its managed catastrophe premiums for the year. The Company now expects its managed catastrophe premiums for the year will decrease by approximately 5% from 2006. In addition, the Company now expects its specialty reinsurance premiums to grow by approximately 35% in 2007; the Company's previous guidance was for its specialty reinsurance premiums to be essentially flat for the year. The Company now expects its Individual Risk premiums to be down by at least 10% in 2007; the Company's previous guidance was for its Individual Risk premiums to be essentially flat for the year. The reduction in the Company's expected decline in managed catastrophe premiums for 2007 is due to better than expected renewals during the second quarter of 2007. The increase in the Company's specialty reinsurance premium forecast for 2007 is due principally to one large transaction that incepted in the second quarter of 2007. The decrease in the Company's forecasted Individual Risk premium is due to softening market conditions.

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 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 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 - diluted" 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 - diluted to operating income available to common shareholders per common share - diluted; 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 premiums" and "managed catastrophe premiums, net of fully-collateralized joint ventures." "Managed catastrophe premiums" is defined as gross catastrophe premiums written by Renaissance Reinsurance and its related joint ventures. "Managed catastrophe premiums" differ from total catastrophe premiums, which the Company believes is the most directly comparable GAAP measure, due to the inclusion of catastrophe premiums written on behalf of the Company's joint venture Top Layer Re, which is accounted for under the equity method of accounting. "Managed catastrophe premiums, net of fully-collateralized joint ventures" differ from total catastrophe premiums, which the Company believes is the most directly comparable GAAP measure, due to: 1) the inclusion of catastrophe premiums written on behalf of the Company's joint venture Top Layer Re, which is accounted for under the equity method of accounting; and 2) the deduction of catastrophe premiums that are written by the Company and ceded directly to the Company's fully-collateralized joint ventures which include Starbound Re, Starbound II and Timicuan Reinsurance Ltd. The Company's management believes "managed catastrophe premiums" is useful to investors and other interested parties because it provides a measure of total catastrophe reinsurance premiums assumed by the Company through its consolidated subsidiaries and related joint ventures. The Company believes "managed catastrophe premiums, net of fully-collateralized joint ventures" is also a useful measure to investors and other interested parties because it provides a measure of total catastrophe reinsurance premiums assumed by the Company through its consolidated subsidiaries and related joint ventures, net of catastrophe premiums written directly on behalf of the Company's fully-collateralized joint ventures.
