shareholders of $274.5 million in 2005. Net operating income (loss) excludes net realized investment losses of $34.5 million and $7.0 million for 2006 and 2005, respectively. Net operating income per common share was $11.05 in 2006, compared to a net operating loss per common share of $3.89 in 2005. Net income available to common shareholders was $761.6 million or $10.57 per common share in 2006, compared to a net loss attributable to common shareholders of $281.4 million or a net loss of $3.99 per common share for 2005.

The Company generated an operating return on average common equity of 37.9% for the year, compared to a negative 13.3% operating return on average common equity in 2005. The Company’s book value per common share increased 40.2% in 2006, compared to an 18.8% decrease in 2005. The Company’s 2006 results benefited significantly from light insured catastrophe loss activity compared to 2005.

Underwriting Results

Gross premiums written for 2006 were $1,943.6 million, a $134.5 million increase from 2005. The increase was principally driven by growth in the Company’s property catastrophe premium within the Company’s Reinsurance segment. As described in more detail below, the Company generated $693.3 million of underwriting income and had a combined ratio of 54.7% in 2006, compared to a $556.4 million underwriting loss and 139.7% combined ratio in 2005. The underwriting loss in 2005 was principally driven by Hurricanes Katrina, Rita and Wilma which occurred in 2005 and resulted in a $1,136.9 million underwriting loss ($891.9 million net negative impact). The Company experienced $136.6 million of favorable development on prior year reserves in 2006, compared to $241.5 million of favorable development in 2005. The favorable development in 2006 was principally attributable to lower than expected claims emergence in the Company’s specialty reinsurance unit.

Reinsurance Segment

Gross premiums written for the Company’s Reinsurance segment increased $118.2 million to $1,321.2 million in 2006, compared to $1,203.0 million in 2005, primarily due to a significant increase in the Company’s property catastrophe premium and partially offset by a decrease in the Company’s specialty reinsurance premium. For the year, the Company’s managed catastrophe premium, net of fully collateralized joint ventures, and its specialty premium, totaled $971.8 million and $222.0 million, respectively, compared to $791.9 million and $427.4 million, respectively, in 2005. Included in the Company’s 2005 managed catastrophe premium, net of fully collateralized joint ventures, and its 2005 specialty reinsurance premium, is $115.0 million and $38.4 million of loss related premium, respectively, related to the 2005 large hurricanes.

The Reinsurance segment generated $636.2 million of underwriting income and had a combined ratio of 34.5% in 2006, compared to a $461.5 million underwriting loss and 148.7% combined ratio in 2005. The underwriting loss in 2005 was principally driven by Hurricanes Katrina, Rita and Wilma which resulted in a $996.8 million underwriting loss ($751.8 million net negative impact). The Company experienced $125.2 million of favorable development on prior year reserves in 2006, compared to $231.3 million of favorable development in 2005. The favorable development in 2006 was principally attributable to lower than expected claims emergence in the Company’s specialty reinsurance unit.

Individual Risk Segment

Gross premiums written for the Company’s Individual Risk segment increased $38.0 million to $689.4 million in 2006, compared to $651.4 million in 2005. The increase was primarily due to an increase in commercial property premium, which more than offset a decrease in personal lines property premium. The Company elected to reduce its quota share personal lines property capacity in 2006 and redeploy this capacity to property catastrophe excess of loss reinsurance in the Company’s Reinsurance segment, where it found the pricing and terms more attractive.

The Individual Risk segment generated $57.0 million of underwriting income and had a combined ratio of 89.8% in 2006, compared to a $94.8 million underwriting loss and 120.8% combined ratio in 2005. The underwriting loss in 2005 was principally driven by Hurricanes Katrina, Rita and Wilma which resulted in a $140.1 million underwriting loss ($140.1 million net negative impact).

Other Items

•

Net investment income increased $100.9 million to $318.1 million for 2006, as a result of an increase in the Company’s average invested assets, combined with higher yields on the Company’s portfolio of fixed maturity investments available for sale and short term investments. Other investments, which include private equity and hedge fund investments, contributed $65.7 million to the Company’s net investment income in 2006 compared to $59.3 million in 2005.

•

Corporate expenses of $24.4 million were incurred during 2006, compared to $71.8 million in 2005. The decrease in such expenses is due in part 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. These costs totaled $5.3 million in 2006 compared to $39.7 million in 2005. As noted above, the Company also incurred $13.3 million of compensation expense in 2005 related to the departure of the Company’s former Chairman and CEO in the fourth quarter of 2005.

•	The Company’s cash flows from operations were $813.3 million in 2006, compared to $335.6 million in 2005.

This press release includes certain non-GAAP financial measures including ‘‘operating income (loss) available (attributable) to common shareholders,’’ ‘‘operating income (loss) available (attributable) to common shareholders per common share – diluted,’’ ‘‘operating return on average common equity, annualized,’’ ‘‘managed catastrophe premiums’’ and ‘‘managed catastrophe premiums, net of fully-collateralized joint ventures.’’ A reconciliation of such measures to the most comparable GAAP figures in accordance with Regulation G is presented in the attached supplemental financial data.

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 (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 income (loss)’’ as used herein differs from ‘‘net income (loss) available (attributable) 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 (loss)’’ 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 (loss)’’ to calculate ‘‘operating income (loss) per common share’’ and ‘‘operating return on average common equity, annualized.’’ The following is a reconciliation of: 1) net income (loss) available (attributable) to common shareholders to operating income (loss) available (attributable) to common shareholders; 2) net income (loss) available (attributable) to common shareholders per common share to operating income (loss) available (attributable) to common shareholders per common share; and 3) return on average common equity, annualized to operating return on average common equity, annualized:

(1)	In accordance with FAS 128, earnings per share calculations use average common shares outstanding – basic, when in a net loss position.

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, excluding catastrophe premiums assumed from the Company’s Individual Risk segment. ‘‘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 and the exclusion of catastrophe premiums assumed from the Company’s Individual Risk segment. ‘‘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; 2) the exclusion of catastrophe premiums assumed from the Company’s Individual Risk segment; and 3) 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 Reinsurance Ltd. 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 assumed from the Company’s Individual Risk segment and net of catastrophe premiums written directly on behalf of the Company’s fully-collateralized joint ventures.
