Net premiums written include $361.6 million in net premiums written for the Company's Reinsurance segment in the second quarter of 2006, compared to $184.5 million for the same quarter of 2005. Net premiums earned include $278.1 million in net premiums earned for the Company's Reinsurance segment in the second quarter of 2006, compared to $206.7 million for the same quarter of 2005.

Premiums for the second quarter of 2006 include $158.1 million of gross premiums written, $129.5 million of net premiums written and $76.7 million of net premiums earned by the Company's consolidated joint venture, DaVinci Reinsurance Ltd. (‘‘DaVinci’’), compared to $32.2 million of gross premiums written, $32.2 million of net premiums written and $42.2 million of net premiums earned by DaVinci during the second quarter of 2005. Since December 2005, DaVinci has raised $374.3 million in equity capital (December 2005 and February 2006) and has increased its funded bank debt by $60.0 million (April 2006) to support its growth.

Individual Risk

Gross premiums written include $210.8 million in gross premiums written for the Company's Individual Risk segment in the second quarter of 2006, compared to $220.1 million for the same quarter of 2005. The decrease in gross premiums written was principally due to termination of several catastrophe exposed quota share contracts on a portfolio transfer basis, which resulted in the transfer of $60.3 million of unearned premium back to the quota share reinsureds and resulted in a decrease in gross premiums written of the same amount. Net premiums written include $150.7 million in net premiums written for the Company's Individual Risk segment in the second quarter of 2006, compared to $203.4 million for the same quarter of 2005. Net premiums earned include $152.9 million in net premiums earned for the Company's Individual Risk segment in the second quarter of 2006, compared to $132.1 million for the same quarter of 2005.

Underwriting Ratios, Reserve Development

For the second quarter of 2006, the Company generated a combined ratio of 72.2%, a loss ratio of 48.1% and an underwriting expense ratio of 24.1%, compared to a combined ratio, loss ratio and underwriting expense ratio of 52.5%, 32.1% and 20.4%, respectively, for the second quarter of 2005. During the second quarter of 2006, the Company recorded favorable development on prior year reserves of $11.3 million or a decrease of 2.6 percentage points in the Company's quarterly loss ratio. This compares to favorable development of $65.1 million in the second quarter of 2005 which decreased the Company's second quarter 2005 loss ratio by 19.2 percentage points. The favorable development in 2005 was driven by the impact of the Company's catastrophe reserve review. Net paid losses for the quarter were $117.9 million compared to $149.2 million in the second quarter of 2005.

Reinsurance Segment

The Company's Reinsurance segment generated a loss ratio of 35.2% and an underwriting expense ratio of 18.3% for the second quarter of 2006, compared to a loss ratio and underwriting expense ratio of 12.6% and 14.8%, respectively, for the second quarter of 2005. The results for the second quarter of 2006 include $100.8 million of current accident year net claims and claim expenses resulting in a current accident year loss ratio of 36.2%, compared to current accident year net claims and claim expenses and a current accident year loss ratio of $91.8 million and 44.4%, respectively, for the second quarter of 2005. During the second quarter of 2006, the Company's Reinsurance segment experienced $2.8 million of favorable development on prior year reserves or a decrease of 1.0 percentage point to the Company's Reinsurance segment quarterly loss ratio. Included in the underwriting result in the second quarter of 2005 was a net reduction in prior year claims incurred of $65.7 million which reduced the Company's second quarter 2005 Reinsurance segment loss ratio by 31.8 percentage points. The favorable development in the second quarter of 2005 was principally the result of the Company's catastrophe reserve review which resulted in a $118.2 million decrease of prior year reserves and increased the Company's net income by $108.2 million, after minority interest. This favorable development in 2005 was partially offset by $52.5 million of adverse development on prior year reserves in the second quarter of 2005, including $37.3 million from the 2004 hurricanes.

Individual Risk Segment

The Company's Individual Risk segment generated a loss ratio of 71.6% and an underwriting expense ratio of 34.5% for the second quarter of 2006, compared to a loss ratio and underwriting expense ratio of 62.6% and 29.0%, respectively, for the second quarter of 2005. The results for the second quarter of 2006 include $117.9 million of current accident year net claims and claim expenses resulting in a current accident year loss ratio of 77.1%, compared to current accident year net claims and claim expenses and a current accident year loss ratio of $82.0 million and 62.1%, respectively, in the second quarter of 2005. The 15.0 percentage points increase in the current accident year loss ratio was due primarily to additional earned premiums on a seasonal program which has a higher attritional loss ratio than the rest of the Individual Risk business as well as several large per risk losses within the Company's Individual Risk quota share business. The Company's U.S. casualty program business continues to perform as expected. During the quarter, the Company's Individual Risk segment experienced $8.5 million of favorable development on prior year reserves or a decrease of 5.5 percentage points to the Company's Individual Risk quarterly loss ratio. In the second quarter of 2005, the Company experienced $0.7 million of adverse development on prior year reserves or an increase of 0.5 percentage points to the Company's Individual Risk quarterly loss ratio.

Fully-Collateralized Joint ventures

During the second quarter of 2006 the Company participated in the establishment of two new fully-collateralized joint ventures, Starbound Re and Tim Re. These joint ventures 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 considerations. The premium for these joint ventures 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 these joint ventures. The limit ceded to these joint ventures, including any reinstated limits, is fully-collateralized by highly-rated short term and fixed maturity investments as well as the premium receivable.

In conjunction with the Starbound Re transaction the Company made a $7.5 million equity investment in Starbound Holdings Ltd. (‘‘Starbound’’), representing a 5.9% ownership interest. This equity investment is accounted for under the equity method of accounting. With respect to Tim Re, the Company sold non-voting Class B shares in this entity, a previously wholly-owned subsidiary of the Company, to unrelated third party investors for $49.5 million during the quarter. The Class B shareholders will earn an underwriting profit or loss based on the performance of the contracts assumed by Tim Re. Tim Re remains a consolidated subsidiary of the Company. The Class B capital structure of Tim Re provides indemnification of losses relating to insurance risk assumed from the Company and is therefore accounted for as ceded reinsurance in the Company's consolidated financial statements.

Equity in Earnings of Other Ventures

Equity in earnings of other ventures generated $9.2 million in income in the second quarter of 2006 compared to $7.8 million in income in the second quarter of 2005. The Company's equity in earnings of other ventures in 2006 now includes the equity in earnings of Starbound, in addition to the equity in earnings of its investments in Top Layer Reinsurance Ltd. (‘‘Top Layer Re’’), ChannelRe Holdings Ltd. (‘‘ChannelRe’’) and Tower Hill Holdings Inc. (‘‘Tower Hill’’). The increase was principally due to a $0.9 million and a $0.4 million increase of the equity in earnings from ChannelRe and Tower Hill, respectively, along with $0.3 million of equity in earnings from Starbound.

Other Income

During the second quarter of 2006 the Company recognized a $0.1 million other loss on fees and other items compared to $3.2 million of other income in the second quarter of 2005. Fee income was $1.5 million in the second quarter of 2006 compared to $1.0 million for the second quarter of 2005. Other items generated a loss of $1.6 million in the second quarter of 2006, principally driven by a $2.2

---

million mark-to-market loss on the Company's warrant to purchase 2.5 million shares of Platinum Underwriters Holding Ltd. (‘‘Platinum’’) common stock, compared to income of $2.2 million in the second quarter of 2005, which included a $2.3 million increase in the fair value of the Company's Platinum warrant.

Net Investment Income and Net Realized Gains and Losses on Investments

Net investment income for the second quarter of 2006 was $74.0 million, compared to $45.8 million for the same quarter in 2005, principally reflecting a higher yield on the Company's portfolio of fixed maturity investments available for sale and short term investments, combined with an increased level of average invested assets. Other investments, which include the Company's hedge fund and private equity investments, generated $11.1 million of net investment income in the second quarter of 2006 compared with $7.1 million in the second quarter of 2005.

During the second quarter of 2006, the Company recorded $24.3 million of net realized losses compared to $1.6 million of net realized gains in the second quarter of 2005. Included in net realized losses are other than temporary impairment charges of $23.7 million and $0.6 million in the second quarter of 2006 and 2005, respectively, with respect to the Company's portfolio of fixed maturity investments available for sale. Principally all of the other than temporary impairment charges are due to rising interest rates.

Regulatory Update; Proposed SEC Settlement

The Company has submitted an offer of settlement to the Securities and Exchange Commission (‘‘SEC’’) in connection with the SEC's investigation relating to the Company's restatement of its financial statements for the years ended December 31, 2001, 2002 and 2003. Pursuant to the offer of settlement, which the SEC staff has indicated that it will recommend to the SEC Commissioners, the Company will consent, without admitting or denying any wrongdoing, to entry of a final judgment enjoining future violations of certain provisions of the federal securities laws and ordering the Company to pay disgorgement of $1 and a civil penalty of $15 million. The Company will also retain an independent consultant to review certain of the Company's internal controls, policies and procedures as well as the design and implementation of the review conducted by independent counsel reporting to the non-executive members of the Company's Board of Directors and procedures performed by the Company's auditors in connection with their audit of the Company's financial statements for the fiscal year ended December 31, 2004. The amount of the monetary penalty discussed above has been previously provided for.

The proposed settlement, which has the support of the SEC staff, remains subject to approval by the SEC Commissioners, and by the federal court in which the SEC's complaint against the Company will be filed. The Company can give no assurances that the proposed settlement will receive the necessary approvals. If the proposed settlement is not approved, the Company could be subject to different or additional remedies, both monetary and non-monetary, which could adversely affect the Company's business or financial statements, perhaps materially. Disposition of the SEC's investigation relating to the Company's restatement would not dispose of the ongoing investigation by the United States Attorney's Office for the Southern District of New York, which the Company has previously disclosed in its filings with the SEC. The Company continues to fully cooperate with governmental authorities as to this investigation. The SEC settlement also does not include the plaintiffs in the consolidated securities class action lawsuit pending against the Company and certain of its current and former officers. The Company intends to vigorously defend this lawsuit, which it believes is without merit.

Other Items

Corporate expenses of $5.6 million were incurred during the second quarter of 2006 compared to $8.7 million in the second quarter of 2005. The difference in such expenses principally relates to the difference in costs incurred related to the Company's internal review and the ongoing investigations into the Company and certain of its present and former executive officers by governmental authorities, which totaled $1.1 million in the second quarter of 2006 compared to $4.7 million in the second quarter of 2005.

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 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’’ 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 to operating income available to common shareholders per common share; 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 premium 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 and Tim Re. 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.
