PEMBROKE, Bermuda--(BUSINESS WIRE)-- RenaissanceRe Holdings Ltd. (NYSE: RNR) today reported a net loss attributable to RenaissanceRe common shareholders of $248.0 million or $4.69 per diluted common share in the first quarter of 2011, compared to net income available to RenaissanceRe common shareholders of $165.0 million or $2.73 per diluted common share in the first quarter of 2010. Operating loss attributable to RenaissanceRe common shareholders was $242.9 million or $4.59 per diluted common share for the first quarter of 2011, compared to operating income available to RenaissanceRe common shareholders of $116.5 million or $1.91 per diluted common share in the first quarter of 2010. The Company reported an annualized return on average common equity of negative 31.3% and an annualized operating return on average common equity of negative 30.7% in the first quarter of 2011, compared to positive 20.9% and positive 14.8%, respectively, in the first quarter of 2010. See Comments on Regulation G for a reconciliation of non-GAAP measures.

Book value per common share decreased $5.57, or 8.9%, in the first quarter of 2011 to $57.01, compared to a 4.2% increase in the first quarter of 2010.

Neill A. Currie, CEO, commented: "This quarter's catastrophic events have caused enormous human tragedy, and we extend our sympathies to all those affected. As we have throughout the history of our Company, we are responding to the needs of our clients quickly, whether it is paying valid claims with industry leading speed, or providing additional coverage in the wake of these events."

Mr. Currie commented further: "In the aftermath of the large catastrophes that have occurred over the last year, and as our clients' view of risk evolves, we anticipate demand for our products will increase over time. Our experienced team has the tools and the capital necessary to respond to the needs of our clients."

FIRST QUARTER 2011 HIGHLIGHTS (1)

    --  Gross premiums written increased $94.5 million, or 18.3%, to $610.5
        million, primarily driven by reinstatement premiums written from the
        large catastrophes of the first quarter of 2011 and increases across
        most lines of business within the Lloyd's segment. Excluding the impact
        of $113.5 million and $27.0 million of reinstatement premiums written in
        the first quarter of 2011 and 2010, respectively, gross premiums written
        increased $8.0 million, or 1.6%.
    --  Underwriting loss of $397.2 million and a combined ratio of 230.0%,
        principally due to the Australian flooding, the February 2011 New
        Zealand earthquake and the Tohoku earthquake, as detailed in the table
        below, which had a net negative impact (2)of $427.4 million and added
        212.3 percentage points to the combined ratio.

Underwriting Results by Segment (1)

Reinsurance Segment

Gross premiums written in the Reinsurance segment were $573.7 million, an increase of $75.1 million, or 15.1%. The increase is primarily due to a $74.6 million increase in the catastrophe reinsurance unit as a result of reinstatement premiums written on the February 2011 New Zealand earthquake and the Tohoku earthquake, and partially offset by the then softening market conditions on a risk-adjusted basis in our core markets during the January 2011 renewals. Excluding the impact of $112.8 million and $27.0 million of reinstatement premiums written in the first quarter of 2011 and 2010, respectively, Reinsurance segment gross premiums written declined $10.7 million, or 2.3%, and managed catastrophe premiums written declined $13.0 million, or 3.0%.

The Reinsurance segment incurred an underwriting loss of $368.1 million and a combined ratio of 227.2%, compared to underwriting income of $87.4 million and a combined ratio of 64.0%. Current accident year net claims and claim expenses in the Reinsurance segment of $667.4 million are comprised of $606.2 million and $61.1 million related to the catastrophe and specialty units, respectively. As detailed in the table below, the large catastrophes of the first quarter of 2011 had a net impact on the Reinsurance segment underwriting result of $544.7 million and added 220.9 percentage points to the Reinsurance segment's combined ratio.

ratio



The Reinsurance segment experienced $72.0 million of favorable development on prior year reserves, including $19.7 million in the catastrophe unit due to reductions in estimated ultimate losses on certain specific events, and $52.3 million in the specialty unit, with $18.4 million related to lower than expected claims emergence, $26.8 million associated with actuarial assumption changes and the remainder due to reductions in ultimate losses on large events.

Lloyd's Segment

Gross premiums written in the Lloyd's segment increased by $22.6 million, or 161.1%, to $36.6 million, primarily due to Syndicate 1458 increasing its book of business across all lines of business, most notably in lines within its specialty business. The Lloyd's segment incurred an underwriting loss of $26.3 million and a combined ratio of 267.7%, compared to $2.9 million and 141.7%, respectively. Net claims and claim expenses are comprised primarily of $15.0 million related to the Tohoku earthquake and $6.0 million related to the February 2011 New Zealand earthquake, with the remainder due to incurred but not reported loss activity in the specialty lines of business.

Investments (1)

Total investment result, which includes net investment income, net realized and unrealized (losses) gains on investments, net other-than-temporary impairments and the change in net unrealized gains on fixed maturity investments available for sale, decreased $49.9 million, to $55.3 million, primarily due to the lower total returns on the fixed maturity investments portfolio and certain non-investment grade allocations included in other investments, and partially offset by improved returns on private equity investments. The average yield to maturity on the fixed maturity and short term investment portfolio was 2.1% at March 31, 2011.

Other Income (Loss) (1)

Other income improved $56.3 million to $50.1 million primarily due to:

    --  ceded reinsurance contracts accounted for at fair value generating
        income of $43.5 million, compared to a loss of $1.5 million, as a result
        of net recoverables on the Tohoku earthquake which are included in the
        determination of net negative impact from the large catastrophes of the
        first quarter of 2011;
    --  a $3.0 million gain on the sale of the Platinum warrants, compared to a
        mark-to-market loss of $3.7 million; and
    --  an improvement of $5.1 million in other income from the Company's
        weather and energy risk management operations due to overall more
        favorable trading conditions experienced during the period.

Other Items (1)

    --  Equity in losses of other ventures of $23.8 million declined $25.9
        million from prior year primarily due to our equity in losses of Top
        Layer Re of $22.5 million as a result of net claims and claim expenses
        related to the February 2011 New Zealand earthquake recorded by Top
        Layer Re.
    --  Net loss attributable to the redeemable noncontrolling interests of
        $85.5 million deteriorated from net income attributable to
        noncontrolling interests of $10.6 million, primarily due to the
        decreased profitability of DaVinciRe as a result of the large
        catastrophes of the first quarter of 2011 and an increase in the
        Company's ownership of DaVinciRe to 44.0% at March 31, 2011, compared to
        41.2% at March 31, 2010.
    --  Approximately 2.7 million common shares were repurchased in open market
        transactions at an aggregate cost of $174.8 million and at an average
        share price of $65.84.
    --  On April 1, 2011, DaVinciRe repaid in full the $200.0 million borrowed
        under the DaVinciRe Credit Agreement.

This Press Release includes certain non-GAAP financial measures including "operating (loss) income (attributable) available to RenaissanceRe common shareholders", "operating (loss) income (attributable) available to RenaissanceRe common shareholders per common share - diluted", "operating return on average common equity - annualized" and "managed catastrophe premiums". A reconciliation of such measures to the most comparable GAAP figures in accordance with Regulation G is presented in the attached supplemental financial data.

RenaissanceRe Holdings Ltd. will host a conference call on Wednesday, April 27, 2011 at 10:00 a.m. (ET) to discuss this release. Live broadcast of the conference call will be available through the "Investor Information - Company Webcasts" section of RenaissanceRe's website at www.renre.com.

RenaissanceRe Holdings Ltd. is a global provider of reinsurance and insurance. The Company's business consists of three segments: (1) Reinsurance, which includes catastrophe reinsurance, specialty reinsurance and certain property catastrophe and specialty joint ventures managed by the Company's ventures unit, (2) Lloyd's, which includes reinsurance and insurance business written through Syndicate 1458, and (3) Insurance, which principally includes the Company's Bermuda-based insurance operations.

Cautionary Statement under "Safe Harbor" Provisions of the Private Securities Litigation Reform Act of 1995: Statements made in this earnings release contain information about the Company's future business prospects. These statements may be considered "forward-looking." These statements are subject to risks and uncertainties that could cause actual results to differ materially from those set forth in or implied by such forward-looking statements. For further information regarding cautionary statements and factors affecting future results, please refer to RenaissanceRe Holdings Ltd.'s filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the year ended December 31, 2010 and its Quarterly Reports on Form 10-Q.

(1) All comparisons are with the first quarter of 2010 unless specifically stated.

(2) Net negative impact includes the sum of estimates of net claims and claim expenses incurred, earned reinstatement premiums assumed and ceded, lost profit commissions, redeemable noncontrolling interest, equity in the net claims and claim expenses of Top Layer Re, and other income with respect of ceded reinsurance contracts accounted for at fair value. The Company's estimates are based on a review of its potential exposures, preliminary discussions with certain counterparties and catastrophe modeling techniques. Given the magnitude and recent occurrence of these events, delays in receiving claims data, the contingent nature of business interruption and other exposures, potential uncertainties relating to reinsurance recoveries and other uncertainties inherent in loss estimation, meaningful uncertainty remains regarding losses from these events. Accordingly, the Company's actual net negative impact from these events will vary from these preliminary estimates, perhaps materially so. Changes in these estimates will be recorded in the period in which they occur.

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 (loss) income (attributable) available to RenaissanceRe common shareholders" 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) income (attributable) available to RenaissanceRe common shareholders" as used herein differs from "net (loss) income (attributable) available to RenaissanceRe common shareholders," which the Company believes is the most directly comparable GAAP measure, by the exclusion of net realized and unrealized gains and losses on investments from continuing and discontinued operations and net other-than-temporary impairments from continuing and discontinued operations. The Company's management believes that "operating (loss) income (attributable) available to RenaissanceRe common shareholders" 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 fixed maturity investment portfolio and equity investments trading. The Company also uses "operating (loss) income (attributable) available to RenaissanceRe common shareholders" to calculate "operating (loss) income (attributable) available to RenaissanceRe common shareholders per common share - diluted" and "operating return on average common equity - annualized". The following is a reconciliation of: 1) net (loss) income (attributable) available to RenaissanceRe common shareholders to operating (loss) income (attributable) available to RenaissanceRe common shareholders; 2) net (loss) income (attributable) available to RenaissanceRe common shareholders per common share - diluted to operating (loss) income (attributable) available to RenaissanceRe 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". "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 Insurance segment. "Managed catastrophe premiums" differs from total catastrophe unit gross premiums written, 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, the inclusion of catastrophe premiums written on behalf of the Company's Lloyd's segment, and the exclusion of catastrophe premiums assumed from the Company's Insurance segment. The Company's management believes "managed catastrophe premiums" is useful to investors and other interested parties because it provides a measure of total catastrophe premiums, as applicable, assumed by the Company through its consolidated subsidiaries and related joint ventures.
