NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in tables expressed in thousands of U.S. dollars, except for share amounts, per share amounts and percentages)

1. ORGANIZATION

Flagstone Reinsurance Holdings, S.A. (“Flagstone” or the “Company”) is a holding company incorporated as a société anonyme under the laws of Luxembourg. On May 14, 2010, the Company’s shareholders approved the redomestication to change the Company’s jurisdiction of incorporation from Bermuda to Luxembourg and the Company thereby discontinued its existence as a Bermuda company as provided in Section 132G of The Companies Act 1981 of Bermuda and continued its existence as a société anonyme under the laws of Luxembourg effective May 17, 2010 (the “Redomestication”). As a result of the Redomestication, the Company changed its name from Flagstone Reinsurance Holdings Limited to Flagstone Reinsurance Holdings, S.A. The Company was originally incorporated on October 4, 2005 under the laws of Bermuda.

2. BASIS OF PRESENTATION AND CONSOLIDATION

These unaudited condensed consolidated financial statements include the accounts of Flagstone and its wholly owned subsidiaries, including Flagstone Réassurance Suisse S.A. (“Flagstone Suisse”), and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. References in this Quarterly Report on Form 10-Q (this “Quarterly Report”) to “dollars” or “$” are to the lawful currency of the United States of America, unless the context otherwise requires. All amounts in the following tables, unless otherwise stated, are expressed in thousands of U.S. dollars, except share amounts, per share amounts and percentages. References in this Quarterly Report to (i) “foreign currency” are to currencies other than U.S. dollars and (ii) “foreign exchange” transactions or “foreign investments” are to transactions or investments, respectively, involving currencies other than U.S. dollars, in each case unless the context otherwise requires. References in this Quarterly Report to “foreign subsidiaries” are to subsidiaries of Flagstone that are not domiciled in the United States of America or whose primary transactions are in foreign currency. These unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries, including those that meet the consolidation requirements of variable interest entities (“VIEs”). The Company assesses the consolidation of VIEs based on whether the Company is the primary beneficiary of the entity in accordance with the Consolidation Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”). Entities in which the Company has an ownership of more than 20% and less than 50% of the voting shares are accounted for using the equity method. All intercompany accounts and transactions have been eliminated on consolidation.

The preparation of these unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the disclosed amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company's principal estimates are for loss and loss adjustment expenses (“LAE”), estimates of premiums written, premiums earned, acquisition costs, fair value of investments and share based compensation. The Company reviews and revises these estimates as appropriate based on current information. Any adjustments made to these estimates are reflected in the period the estimates are revised.

In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the Company’s financial position and results of operations as at the end of and for the periods presented. The results of operations and cash flows for any interim period will not necessarily be indicative of the results of operations and cash flows for the full fiscal year or subsequent quarters. This Quarterly Report should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010 (the “2010 Annual Report”), filed with the Securities and Exchange Commission (“SEC”) on March 2, 2011.

Fair value disclosure

The valuation technique used to determine the fair value of the financial instruments is the market approach which uses prices and other relevant information generated by market transactions involving identical or comparable assets.

In accordance with the Fair Value Measurements and Disclosures Topic of the FASB ASC, the Company has classified its investments in U.S. government treasury securities and listed equity securities as Level 1 in the fair value hierarchy. The fair value of these securities is the quoted market price of these securities, as provided either by independent pricing services or exchange market prices.

Investments in U.S. government agency securities, corporate bonds, mortgage-backed securities, foreign government bonds and asset-backed securities are classified as Level 2 in the fair value hierarchy. The fair value of these securities is derived from broker quotes based on inputs that are observable for the asset, either directly or indirectly, such as yield curves and transactional history. Catastrophe bonds are classified as Level 2 in the fair value hierarchy as determined by reference to broker indications. Those indications are based on current market conditions, including liquidity and transactional history, recent issue price of similar catastrophe bonds and seasonality of the underlying risks.

Investments in private equity funds and the mortgage-backed investments fund are classified as Level 3 in the fair value hierarchy. The fair value of the private equity funds is determined by the investment fund managers using the net asset value provided by the administrator or manager of the funds on a quarterly basis and adjusted based on analysis and discussions with the fund managers. The fair value of the mortgage-backed investment fund is determined by the net asset valuation provided by the independent administrator of the fund. These valuations are then adjusted for cash flows since the most recent valuation, which is a methodology generally employed in the investment industry.

5. DERIVATIVES

The Company accounts for its derivative instruments using the Derivatives and Hedging Topic of the FASB ASC, which requires an entity to recognize all derivative instruments as either assets or liabilities on the balance sheet and measure those instruments at fair value, with the fair value recorded in other assets or liabilities. The accounting for realized and unrealized gains and losses associated with changes in the fair value of derivatives depends on the hedge designation and, if designated as a hedging instrument, whether the hedge is effective in achieving offsetting changes in the fair value of the asset or liability being hedged. The realized and unrealized gains and losses on derivatives not designated as hedging instruments are included in net realized and unrealized gains and losses in the consolidated financial statements. Gains and losses associated with changes in fair value of the designated hedge instruments are recorded with the gains and losses on the hedged items, to the extent that the hedge is effective.

The Company enters into derivative instruments such as interest rate futures contracts, foreign currency forward contracts and currency swaps in order to manage portfolio duration and interest rate risk, borrowing costs and foreign currency exposure. The Company enters into index futures contracts and total return swaps to gain exposure to the underlying asset or index. The Company also purchases “to be announced” mortgage-backed securities (“TBAs”) as part of its investing activities. The Company manages the exposure to these instruments in accordance with guidelines established by management and approved by the Company’s Board of Directors (the “Board”).

The Company has entered into certain foreign currency forward contracts for the purpose of hedging its net investments in foreign subsidiaries, and has designated these as hedging instruments. These foreign currency forward contracts are carried at fair value and the realized and unrealized gains and losses are recorded in other comprehensive income as part of the cumulative translation adjustment, to the extent that these are effective as hedges. All other derivatives are not designated as hedges, and accordingly, these instruments are carried at fair value, with the fair value recorded in other assets or liabilities with the corresponding realized and unrealized gains and losses included in net realized and unrealized gains and losses.

On March 25, 2011, Mont Fort Re Limited (“Mont Fort”) repurchased 28.1 million preferred shares relating to its third cell, Mont Fort High Layer, for $46.5 million.

The Company has considered the implications of these share repurchases as they relate to the FASB ASC Topic on Consolidations, specifically relating to variable interest entities, and has concluded that the Company remains the primary beneficiary and should continue to consolidate Mont Fort.

8. DEBT AND FINANCING ARRANGEMENTS

Long term debt

Interest expense includes interest payable and amortization of debt offering expenses. The debt offering expenses are amortized over the period from the issuance of the Deferrable Interest Debentures to the earliest date that they may be called by the Company. For the three months ended March 31, 2011, the Company incurred interest expense of $2.6 million on the Deferrable Interest Debentures compared to $2.5 million for the same period in 2010. The Company had $0.8 million of interest payable included in other liabilities at both March 31, 2011 and December 31, 2010.

The Company does not carry its long term debt at fair value on its consolidated balance sheets. At March 31, 2011, the Company estimated the fair value of its long term debt to be approximately $224.3 million compared to $220.5 million at December 31, 2010.

Letter of credit facilities

On March 5, 2009, Flagstone Suisse entered into a $200.0 million secured committed letter of credit facility with Barclays Bank Plc (the “Barclays Facility”). On March 5, 2011, both Barclays and Company agreed to amend the Barclays Facility to extend the maturity date to July 29, 2011 to allow for the renegotiation of the agreement. The Barclays Facility is used to support the reinsurance obligations of the Company. As at March 31, 2011, $32.3 million had been drawn under the Barclays Facility, and the drawn amount was secured by $35.9 million of fixed maturity securities from the Company’s investment portfolio.

On April 28, 2010, Flagstone Suisse and Flagstone Capital Management Luxembourg SICAF – FIS entered into a secured $450.0 million standby letter of credit facility with Citibank Europe Plc (the “Citi Facility”). The Citi Facility comprised a $225.0 million facility for letters of credit with a maximum tenor of 15 months, to be used to support reinsurance obligations of the Company, and a $225.0 million facility for letters of credit drawn in respect of Funds at Lloyd’s with a maximum tenor of 60 months. On December 21, 2010, the Citi Facility was amended to increase the amount available under the facility by $100.0 million to $550.0 million, with all the terms and conditions remaining unchanged. The Citi Facility now comprises a $275.0 million facility for letters of credit with a maximum tenor of 15 months, to be used to support reinsurance obligations of the Company, and a $275.0 million facility for letters of credit drawn in respect of Funds at Lloyd’s with a maximum tenor of 60 months. As at March 31, 2011, $406.6 million had been drawn under the Citi Facility, and the drawn amount of the facility was secured by $479.6 million of fixed maturity securities from the Company’s investment portfolio. The Citi Facility replaced a $450.0 million credit facility with Citibank Europe Plc which commenced on January 22, 2009.

These facilities are used to provide security to reinsureds and for Funds at Lloyd’s, and they are fully collateralized by the Company, to the extent of the letters of credit outstanding at any given time.

9. SHARE BASED COMPENSATION

The Company accounts for share based compensation in accordance with the Compensation – Stock Compensation Topic of the FASB ASC which requires entities to measure the cost of services received from employees and directors in exchange for an award of equity instruments based on the grant date fair value of the award. The cost of such services will be recognized as compensation expense over the period during which an employee or director is required to provide service in exchange for the award. The Company’s share based compensation plans consist of Performance Share Units (“PSUs”) and Restricted Share Units (“RSUs”).

Performance Share Units

The Company’s Performance Share Unit Plan (“PSU Plan”) is the Company’s shareholder approved primary executive long term incentive scheme. Pursuant to the terms of the PSU Plan, at the discretion of the Compensation Committee of the Board, PSUs may be granted to executive officers and certain other key employees. The number of units that will be exercised at the end vesting period is contingent upon the Company meeting certain diluted return-on-equity (“DROE”) goals.

A summary of the activity under the PSU Plan as at March 31, 2011, and changes during the three months ended March 31, 2011, is as follows:

	For the three months ended March 31, 2011

The Company reviews its assumptions in relation to the PSUs on a quarterly basis. The issuance of shares with respect to the PSUs is contingent upon the attainment of certain levels of average DROE over a three year period. Considering the net loss incurred in the three months ended March 31, 2011, and considering the potential impact on the Company’s ability to meet the specified DROE goals, the factor applied to the PSU grants has been reduced. As a result, for the three months ended March 31, 2011, $(4.2) million of compensation expense related to the PSU Plan has been recorded in general and administrative expenses compared to $4.1 million for the same period in 2010. As at March 31, 2011 and December 31, 2010, there was a total of $10.4 million and $12.2 million, respectively, of unrecognized compensation cost related to non−vested PSUs; that cost is expected to be recognized over periods of approximately 1.9 years and 1.5 years, respectively.

Since the inception of the PSU Plan, 1,432,509 PSUs have vested and 2,368,658 PSUs have been cancelled.

Restricted Share Units

The purpose of the Company’s Restricted Share Unit Plan (the “RSU Plan”) is to encourage certain employees and directors of the Company to further the development of the Company and to attract and retain key employees for the Company’s long term success. The RSUs granted to employees vest over a period of approximately two years and RSUs granted to directors vest on the grant date.

A summary of the activity under the RSU Plan as at March 31, 2011, and changes during the three months ended March 31, 2011, is as follows:

	For the three months ended March 31, 2011
	Number		Weighted average	Weighted average
	expected to		grant date	remaining

Exercised	(159,400)		10.21
Outstanding at end of period	614,927		11.81	0.6

Unrecognized compensation cost related to non-vested RSUs was $2.2 million and $0.9 million at March 31, 2011 and December 31, 2010, respectively, and is expected to be recognized over a period of approximately 1.4 year and 1.0 year, respectively. Compensation expenses related to the RSU Plan of $1.2 million were recorded in general and administrative expenses for the three months ended March 31, 2011 compared to $1.1 million for the same period in 2010.

Since the inception of the RSU Plan in July 2006, 544,492 RSUs granted to employees have vested and no RSUs granted to employees have been cancelled. During the three months ended March 31, 2011 and 2010, 63,964 and 64,896 RSUs were granted to the directors, respectively. During both the three months ended March 31, 2011 and 2010, no RSUs granted to directors were converted into common shares of the Company as elected by the directors.

The Company uses a nil forfeiture assumption for its PSUs and RSUs. The intrinsic value of both PSUs and RSUs outstanding as at March 31, 2011 was $17.7 million and $5.5 million, respectively.

10. EARNINGS (LOSS) PER COMMON SHARE

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in tables expressed in thousands of U.S. dollars, except for share amounts, per share amounts and percentages)

Dilutive share equivalents have been excluded in the weighted average common shares used for the calculation of earnings per share in periods of net loss because the effect of such securities would be anti-dilutive. The number of anti-dilutive share equivalents that were excluded in the computation of diluted earnings per share for the three months ended March 31, 2011 was 150,267. Because the number of shares contingently issuable under the PSU Plan depends on the average DROE over a two or three year period, the PSUs are excluded from the calculation of diluted earnings per common share until the end of the performance period, at which time the number of shares issuable under the PSU Plan will be known. As at March 31, 2011 and 2010, there were 1,965,091 and 4,130,213 PSUs expected to vest, respectively. The maximum number of common shares that could be issued under the PSU Plan at March 31, 2011 and 2010 was 4,962,078 and 5,457,105, respectively. Also, at March 31, 2011 and 2010, there was a warrant outstanding which would result in the issuance of 630,194 and 8,585,747 common shares that were excluded from the computation of diluted earnings per common share because the effect would be anti-dilutive.

11. SHAREHOLDERS’ EQUITY

Common shares

At March 31, 2011, the total authorized common voting shares of the Company were 300,000,000, with a par value of $0.01 per common share (December 31, 2010 – 300,000,000).

The following table is a summary of the common shares issued and outstanding for the periods ending March 31, 2011 and December 31, 2010:

	For the periods ended
	March 31, 2011	December 31, 2010
Common voting shares:
Balance at beginning of period	68,585,588	82,985,219

Balance at end of period	70,054,875	68,585,588

(1)Conversion of performance share units and restricted share units are net of shares withheld for the payment of tax on the employee's behalf.

12. LEGAL PROCEEDINGS

In the normal course of business, the Company may become involved in various claims litigation and legal proceedings. Such proceedings often involve reinsurance contract disputes which are typical for the insurance and reinsurance industry. As at March 31, 2011, the Company was not a party to any material litigation or arbitration proceedings.

Executive Overview

We are a global reinsurance and insurance company. Our management views us as being organized into three business segments: Reinsurance, Lloyd’s and Island Heritage. Through our Reinsurance segment, we write primarily property, property catastrophe and short-tail specialty and casualty insurance and reinsurance. Through our Lloyd’s segment, we write primarily property and short-tail specialty and casualty insurance and reinsurance focused on the energy, hull, cargo, marine liability, engineering, and aviation business sectors. Island Heritage primarily writes property insurance for homes, condominiums, office buildings and automobiles in the Caribbean region.

Our financial statements are prepared in accordance with accounting principles generally accepted in the U.S (“U.S. GAAP”) and our fiscal year ends on December 31. Because a substantial portion of the reinsurance we write provides protection from damages relating to natural and man-made catastrophes, our results depend to a large extent on the frequency and severity of such catastrophic events, and the specific coverages we offer to clients affected by these events. This may result in volatility in our results of operations and financial condition. In addition, the amount of premiums written with respect to any particular line of business may vary from quarter to quarter and year to year as a result of changes in market conditions.

We measure our financial success through long term growth in diluted book value per share plus accumulated distributions measured over intervals of three years. We believe this is the most appropriate measure of our performance, a measure that focuses on the return provided to our common shareholders. Diluted book value per share is obtained by dividing Flagstone shareholders’ equity by the number of common shares and common share equivalents outstanding including all potentially dilutive securities such as a warrant, Performance Share Units (“PSUs”) and Restricted Share Units (“RSUs”).

We derive our revenues primarily from net premiums earned on the reinsurance and insurance policies we write, net of any retrocessional or reinsurance coverage purchased, income from our investment portfolio, and fees for services provided. Premiums are generally a function of the number and type of contracts we write, as well as prevailing market prices. Premiums are normally due in installments and earned over the contract term, which ordinarily is 12 or 24 months.

Income from our investment portfolio primarily comprises interest on fixed maturity, short term investments and cash and cash equivalents and net realized and unrealized gains (losses) on our investment portfolio including our derivative positions, net of investment expenses.

Index

Our expenses consist primarily of the following: loss and loss adjustment expenses (“LAE”) incurred on the policies of reinsurance and insurance that we sell; acquisition costs which typically represent a percentage of the premiums that we write; general and administrative expenses which primarily consist of salaries, benefits and related costs, including costs associated with awards under our Performance Share Unit Plan (“PSU Plan”) and Restricted Share Unit Plan (“RSU Plan”), and other general operating expenses; interest expense related to our debt obligations; and noncontrolling interest, which represents the interest of external parties with respect to the net income of Mont Fort, Island Heritage, and Flagstone Africa. We are also subject to taxes in certain jurisdictions in which we operate; however, since the majority of our income to date has been earned in Bermuda, a non-taxable jurisdiction, the tax impact on our operations has historically been minimal. The Company is now a Luxembourg tax resident entity due to its change of jurisdiction of incorporation from Bermuda to Luxembourg effective May 17, 2010 (the “Redomestication”); therefore, it will be subject to Luxembourg corporate income tax, municipal business tax, withholding tax, and net wealth tax. Our management attempts to minimize the income tax impact on the Company through effective tax planning.

As seen across the industry, the first quarter of 2011 was extremely challenging given the large number of significant international catastrophes. While our diversification remains a key strategic differentiator, and has over time resulted in an excellent long-term loss ratio, the international loss activity in the quarter reached record high levels, a historical anomaly which is reflected in our results. However, we believe our overall capitalization remains strong and more than sufficient to withstand A.M. Best’s capital stress test which considers additional shock losses for future events. Combined with our conservative investment portfolio, we are solidly positioned to continue our prudent underwriting practices while providing award winning service and high-quality capacity to our valued clients.

We remained disciplined to start the year, and in the North American book we reduced some of our catastrophe risk on business we felt was not adequately priced. However, due to the amount of global first quarter loss activity, coupled with the potential impact from the recent catastrophe model changes, we have seen an increased demand for catastrophe coverage and a corresponding hardening of rates. Internationally, the first quarter of 2011 was dominated by a historically unprecedented series of losses, beginning in Australia and New Zealand and culminating with the Tohoku earthquake. As a result of these losses, we have seen a significant increase in rates for business in loss affected areas.

Critical Accounting Policies

Our critical accounting policies are discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 of the 2010 Annual Report. Our critical accounting policies at March 31, 2011 have not changed compared to December 31, 2010.

It is important to understand our accounting policies in order to understand our financial position and results of operations. Our unaudited condensed consolidated financial statements contain certain amounts that are inherently subjective in nature and have required our management to make assumptions and best estimates to determine the reported values. If events or other factors, including those described in Item 1A, “Risk Factors,” of the 2010 Annual Report, cause actual events or results to differ materially from management’s underlying assumptions or estimates, there could be a material adverse effect on our results of operations, financial condition and liquidity.

Results of Operations - For the Three Months Ended March 31, 2011 and 2010

Our reporting currency is the U.S. dollar. Our subsidiaries have one of the following functional currencies: U.S. dollar, Swiss franc, Euro, British pound sterling, Canadian dollar, Indian rupee, and South African rand. As a significant portion of our operations are transacted in foreign currencies, fluctuations in foreign exchange rates may affect period-to-period comparisons. To the extent that fluctuations in foreign currency exchange rates affect comparisons, their impact has been quantified, when possible, and discussed in each of the relevant sections. See Note 2 “Significant Accounting Policies” to the consolidated financial statements in Item 8, “Financial Statements and Supplementary Data”, in the Annual Report for a discussion on translation of foreign currencies.

(1)Net (loss) income attributable to Flagstone per common share - Diluted for the three months ended March 31, 2011 does not contain the effect of:
a. a warrant conversion as this would be anti-dilutive for U.S. GAAP purposes
b. the PSU conversion until the end of the performance period, when the number of shares issuable under the PSU Plan will be known. There were 1,965,091 PSU's expected to vest under the PSU plan as at March 31, 2011.
(2)Distributions paid per common share are in the form of a non-dividend return of capital. Prior to the Redomestication, such distributions were in the form of dividends.
(3)NM - not meaningful.

The decrease in underwriting income in the three months ended March 31, 2011, is primarily due to significant catastrophe losses (net of reinsurance and reinstatements) in the period compared to the same period last year. The four main events in the three months ended March 31, 2011, are:

·	Australian floods ($34.4 million; Reinsurance segment - $30.4 million, Lloyd’s segment - $4.0 million);

·	cyclone Yasi ($31.0 million; Reinsurance segment - $31.0 million, Lloyd’s segment - $ nil);

·	New Zealand earthquake ($81.5 million; Reinsurance segment - $79.8 million, Lloyd’s segment - $1.7 million): and

·	Japan earthquake and tsunami ($109.7 million; Reinsurance segment - $97.9 million, Lloyd’s segment - $11.8 million).

The decrease in the net realized and unrealized gains and losses – other, for the three months ended March 31, 2011, is primarily due to net losses associated with the currency swaps and foreign currency forward contracts used for hedging, as a result of currency fluctuation.

These items are discussed in more detail in the following sections.

Non-GAAP Reconciliation

In addition to the U.S. GAAP financial measures set forth in this Quarterly Report, we have presented “basic book value per common share” and “diluted book value per common share”, which are non-GAAP financial measures. Our management uses growth in diluted book value per common share as a prime measure of the value we are generating for our common shareholders, as we believe that growth in our diluted book value per common share ultimately translates into growth in our stock price.

Basic book value per common share is defined as total Flagstone shareholders’ equity divided by the number of common shares outstanding at the end of the period plus vested RSUs, giving no effect to dilutive securities. Diluted book value per common share is defined as total Flagstone shareholders’ equity divided by the number of common shares and common share equivalents outstanding at the end of the period including all potentially dilutive securities such as a warrant, PSUs and RSUs. When the effect of securities would be anti-dilutive, these securities are excluded from the calculation of diluted book value per common share. The warrant was anti-dilutive and was excluded from the calculation of diluted book value per common share as at March 31, 2011 and December 31, 2010.

While we believe that these non-GAAP financial measures provide useful supplemental information to investors, there are limitations associated with the use of these non-GAAP financial measures. Basic book value per common share does not reflect the number of common shares that may be issued upon vesting or exercise of dilutive securities. On the other hand, by giving effect to dilutive securities, diluted book value per common share takes into account common share equivalents and not just the number of common shares actually outstanding. These non-GAAP financial measures are not prepared in accordance with GAAP, are not based on any comprehensive set of accounting rules or principles, are not reported by all of our competitors and may not be directly comparable to similarly titled measures of our competitors due to potential differences in the exact method of calculation. In light of these limitations, we use these non-GAAP financial measures only as supplements to GAAP financial measures and provide a reconciliation of the non-GAAP financial measures to their most comparable GAAP financial measures.

Outlook and Trends

On March 20, 2011, Moody’s Investors Service placed the financial strength rating of the Company and its principal subsidiary, Flagstone Suisse, under review. On March 31, 2011, Fitch Ratings re-affirmed the A- insurer financial strength of Flagstone Suisse and revised its outlook to negative. On April 12, 2011, A.M. Best Co. re-affirmed the A- financial strength rating of Flagstone Suisse and revised its outlook to negative. Currently, the majority of Flagstone Suisse reinsurance contracts permit cancellation if our financial strength rating is downgraded below A- by A.M. Best Co. A downgrade by any rating organization could result in a significant reduction in the number of reinsurance contracts we write and in a substantial loss of business as our customers, and brokers that place such business, move to other competitors with higher financial strength ratings, as well as resulting in negative consequences for our results of operations, cash flows, competitive position and business prospects. In light of the foregoing and the low returns environment, the losses associated with catastrophic events and reductions in our reserves during the first quarter of 2011, there may potentially exist the situation where it is necessary to raise additional capital in the future. Although we regularly provide financial and other information to rating agencies to both maintain and enhance existing financial strength ratings, we cannot assure that our financial strength ratings will not be downgraded in the future by any of these agencies.

North America

At January 1, 2011, we saw North American catastrophe pricing generally down 7 to 10 percent on a risk adjusted basis, and as such we were content to reduce risk by not renewing underpriced business. The Northeast was among the more disappointing regions and we believe it has reached a point where an increasing number of programs are no longer supportable on a marginal pricing basis. The only region that saw some price increases was the Midwest, driven by programs directly affected by the high tornado and hail loss activity of the past three years. Overall, we expect cycle management to play a key role as the year progresses. International large loss activity in the first quarter coupled with the recent catastrophe model change have partially offset this softening trend and increased demand. This positively impacted the April 1 renewals where a number of programs had to re-price from mid single digit % decreases to flat/slight increases in order to get completed. We now foresee North American rates increasing by up to 10% on average for the June and July renewals, and will take the opportunity to strategically underwrite our book of business while offering our capacity and modeling expertise to clients who are impacted by these changes.

Specialty Lines

As in the previous quarter, the treaty and direct and facultative specialty lines remain mixed. We continue to see increasing opportunities in the construction and engineering segment and the marine and energy segments continue to improve following the affects of Deep Horizon and a series of large attritional losses in the first quarter. We are generally seeing improved terms and conditions and are able to take advantage of a better trading environment. Marine hull rates continue to soften, albeit modestly. Aviation, with the exception of treaty excess of loss, remains very challenging with significant over capacity in all aviation segments. Property facultative rates in many regions have turned following the numerous international cat losses and we are seeing encouraging signs in many regions.

International

Following the spate of large cat losses in multiple regions over the last 15 months, we are clearly seeing improved terms and conditions in the majority of regions. This was clearly observed with the April 1 renewals in Japan and Europe and the improved rating levels are expected for the remainder of 2011, with renewals occurring in many loss affected regions. We continue to receive great support from our core global clients and are well position to take advantage of the improved trading conditions for the remainder of 2011. We continue to reduce our exposures in the more competitive markets, especially Asia (excluding Japan) and the Middle East.

Underwriting Results by Segment

Our management views us as being organized into three reportable segments: Reinsurance, Lloyd’s and Island Heritage. We regularly review our financial results and assess our performance on the basis of these three reportable segments in accordance with the Segment Reporting Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”).

Those segments are more fully described as follows:

Reinsurance

Our Reinsurance segment has three main units:

(1)

Property Catastrophe Reinsurance. Property catastrophe reinsurance contracts are typically “all risk” in nature, meaning that they protect against losses from earthquakes and hurricanes, as well as other natural and man-made catastrophes such as tornados, wind, fires, winter storms, and floods (where the contract specifically provides for coverage). Losses on these contracts typically stem from direct property damage and business interruption. To date, property catastrophe reinsurance has been our most important product. We write property catastrophe reinsurance primarily on an excess of loss basis. In the event of a loss, most contracts of this type require us to cover a subsequent event and generally provide for a premium to reinstate the coverage under the contract, which is referred to as a “reinstatement premium”. These contracts typically cover only specific regions or geographical areas, but may be on a worldwide basis. We also provide industry loss warranty covers, which are triggered by loss and loss adjustment expenses incurred by the cedent and some pre-determined absolute level of industry-wide losses resulting from an insured event or by specific parameters of a defined event (such as a magnitude 8 earthquake or a category 4 hurricane).

(2)

Property Reinsurance. We also provide reinsurance on a pro rata share basis and per risk excess of loss basis. Per risk reinsurance protects insurance companies on their primary insurance risks on a single risk basis, for example, covering a single large building. Generally, our property per risk and pro rata business is written with loss limitation provisions, such as per occurrence or per event caps, which serve to limit exposure to catastrophic events.

(3)

Short-tail Specialty and Casualty Reinsurance. We also provide short-tail specialty and casualty reinsurance for risks such as aviation, energy, personal accident and health, satellite, marine and workers’ compensation catastrophe. Generally, our short-tail specialty and casualty reinsurance is written with loss limitation provisions.

Index

Lloyd’s

Our Lloyd’s segment includes the business generated through the Lloyd’s Syndicate 1861 and Flagstone Syndicate Management Limited (“FSML”). Syndicate 1861 primarily provides property and short-tail specialty and casualty insurance and reinsurance for risks such as energy, hull and cargo, marine liability, engineering and aviation. FSML generates fee income from the provision of services to syndicates and third parties.

Island Heritage

Island Heritage is a property and casualty insurer based in the Cayman Islands which is primarily in the business of insuring homes, condominiums, office buildings and automobiles in the Caribbean region.

(4)Includes contracts that cover risks in two or more geographic zones.

Index

Premiums Ceded

In the normal course of our business, we purchase reinsurance in order to manage our exposures. The amount and type of reinsurance that we enter into is dependent on a variety of factors, including the cost of a particular reinsurance cover and the nature of our gross premiums written during a particular period.

The majority of our contracts are excess-of-loss contracts covering one or more lines of business. To a lesser extent we have also purchased quota share reinsurance with respect to specific lines of business. We also purchase protection through catastrophe bond structures, Valais Re and Montana Re, and industry loss warranty policies (“ILWs”) which provide coverage for certain losses provided they are triggered by events exceeding a specified industry loss size. Reinsurance purchases to date have represented prospective cover; that is, ceded reinsurance purchased to protect against the risk of future losses as opposed to covering losses that have already been incurred but have not been paid.

Various factors will continue to affect our appetite and capacity to write and retain risk. These include the impact of changes in frequency and severity assumptions used in our models and the corresponding pricing required to meet our return targets, our available capital, evolving industry-wide capital requirements, increased competition, and other considerations.

·	The decrease in net underwriting results is primarily related to incurred losses on more significant catastrophic events in 2011 (Australian floods, cyclone Yasi, New Zealand earthquake and the Japan earthquake and tsunami), as compared to the same period in 2010 (Chile earthquake).

The increase in gross property and short tail specialty and casualty reinsurance premiums written is primarily due to increased business with existing clients and the addition of new clients. The decrease in gross property catastrophe reinsurance premiums is due to reduction in exposure for the January 1 renewals, partially offset by the increase in reinstatement premiums due to higher catastrophe losses in the first quarter of 2011. During the three months ended March 31, 2011, we recorded $12.0 million of gross reinstatement premiums compared to $3.6 million recorded for the same period in 2010. The increase was due to higher catastrophe losses in the current quarter.

Premiums ceded were 32.4% of gross reinsurance premiums written compared to 19.5% for the same period in 2010. The increase is primarily related to the purchase of additional reinsurance protection to reduce our net exposure to catastrophic events and reinstatement premiums incurred on our ceded reinsurance due to the loss activity in the first quarter of 2011.

The increase in the loss ratio compared to the first quarter of 2010 is primarily due to more significant losses from catastrophic events in the current quarter, including net incurred losses related to the Australian floods ($30.5 million), cyclone Yasi ($31.0 million), New Zealand earthquake ($76.1 million) and the Japan earthquake and tsunami ($99.8 million) compared to the same period in 2010, which included losses related to the Chile earthquake ($57.5 million).

Index

Each quarter we revisit our loss estimates for previous catastrophe events. During the quarter ended March 31, 2011, based on updated estimates provided by clients and brokers, we recorded net adverse developments for prior accident years of $9.3 million, mostly related to Hurricane Ike, a 2008 event. A significant increase in claims was reported from one major cedant due to lawsuits filed before the statute expired. During the first quarter of 2010, the net favorable developments for prior catastrophe events were $7.6 million. In addition, the first quarter of 2010 included $17.1 million of favorable reserves development as a result of revising our actuarial assumptions to take into account our loss experience since inception.

The decrease in general and administrative expenses is primarily the result of our focus, implemented during 2010, on lowering and rationalizing costs and expenses, including the disposal of corporate aircraft. In addition, as a result of the net loss incurred in the three months ended March 31, 2011, performance based compensation expectations have been adjusted downward.

Lloyd’s Segment

·	The decrease in the gross property reinsurance premiums written is primarily attributable to our decision to decline the renewal of certain business due to unfavorable pricing terms.

Premiums ceded were 42.3% of gross premiums written compared to 22.2% of gross premiums written for the same period in 2010. The increase in the premiums ceded ratio is primarily due to changes in the timing of certain reinsurance contracts, which now incept at January 1, together with the purchase of additional reinsurance coverage in 2011.

·	Premiums ceded to Flagstone Suisse under our intercompany reinsurance programs were $6.1 million compared to $5.3 million for the same period in 2010. This amount is eliminated upon consolidation.

·	Other related income, derived from services provided to syndicates and third parties, decreased primarily as a result of the recognition of profit commission from Syndicate 1861’s 2007 year of account, recorded in the first quarter of 2010, in the amount of $7.0 million.

The increase in the loss ratio compared to the first quarter of 2010 was primarily due to more significant losses from catastrophic events in the current quarter, including net incurred losses related to the Australian floods ($4.0 million), New Zealand earthquake ($1.7 million) and the Japan earthquake and tsunami ($12.5 million) compared to the same period in 2010, which included losses related to the Chile earthquake ($2.5 million).

(1)For Island Heritage segment all ratios calculated using expenses divided by net premiums earned plus other related income.

·	The increase in gross premiums written is primarily related to continued growth in the Bahamas. Contracts are written on a per risk basis and consist primarily of property lines.

·	Premiums ceded were 70.3% of gross premiums written compared to 58.6% of gross premiums written for the same period in 2010.

·	Premiums ceded to Flagstone Suisse under our intercompany reinsurance programs were $7.9 million compared to $7.1 million for the same period in 2010. This amount is eliminated on consolidation.

·	Net premiums earned for 2011 were lower compared to the same period in 2010, primarily due to the difference in the reinsurance program in place for both years.

Investment Results

Our investment portfolio is structured to preserve capital and provide us with a high level of liquidity and is managed to produce a total return. In assessing returns under this approach we include investment income and realized and unrealized gains and losses generated by the investment portfolio.

The total return on our investment portfolio, excluding noncontrolling interests in the investment portfolio, comprises investment income and realized and unrealized gains and losses on investments.

	For the three months ended March 31,
	2011		2010		% Change
Investment portfolio return	1.0	%	0.8	%	0.2	%

·	The change in the return on invested assets during three months ended March 31, 2011, compared to the same period in 2010 is primarily due to positive performance of commodities markets and other investments.

Index

Net investment income

Net investment income is derived from interest earned on investments, reduced by investment management and custody fees. We allocate expenses directly related to investments to investment income.

The following table sets forth investment income for the three months ended March 31, 2011 and 2010:

	For the three months ended March 31,

Investment expenses		(1,157)		(952)		(205)
Net investment income	$	9,432	$	7,285	$	2,147

·	The increase in net investment income is principally due to an increase in yield caused by differences in asset allocation.

Net realized and unrealized gains and losses – investments

Net realized and unrealized gains and losses – investments comprises fixed maturities, equities, other investments, and investment portfolio derivatives. We enter into investment portfolio derivatives including global equity, global bond, commodity futures, TBAs, total return swaps and interest rate swaps. We enter into index futures contracts and total return swaps to gain or reduce our exposure to an underlying asset or index. We also purchase TBAs as part of our investing activities. We enter into interest rate swaps and interest rate futures in order to manage portfolio duration and interest rate risk. Exposure to these instruments is managed based on guidelines established by management and is approved by the Board.

The following table is a breakdown of the net realized and unrealized gains (losses) - investments for the three months ended March 31, 2011 and 2010:

	For the three months ended March 31,
	2011		2010		$ Change

Net realized and unrealized (losses) gains on derivatives - investments	$	(26,229)	$	19,756	$	(45,985)

The positive change in net realized and unrealized gains on the fixed maturities was largely offset by the negative change in net realized and unrealized losses on foreign exchange forward contract derivatives which are used for foreign exchange hedging of the non-U.S. dollar bonds. The remaining change is due to tightening of credit spreads in the first quarter of 2010.

·	The change in net realized and unrealized gains on other investments is primarily due to net realized and unrealized gains on catastrophe bonds and investment funds.

·	The change in net realized and unrealized gains on futures contracts is primarily due to positive performance of commodities markets and our duration hedge.

Index

Treasury Hedging and Other

Net realized and unrealized gains and losses – other

Our policy is to hedge the majority of our currency exposure with derivative instruments such as currency swaps and foreign currency forward contracts.

Currency swaps and foreign currency forward contacts are used to hedge the economic currency exposure of our investment in foreign subsidiaries and to hedge operational balances such as premiums receivable, loss reserves and the portion of our long term debt issued in Euros.

Reinsurance derivatives relate to ILWs that are structured as derivative transactions. The amounts shown in the tables below are premiums earned on ILWs.

The following table is the breakdown of net realized and unrealized gains - other for the three months ended March 31, 2011 and 2010:

	For the three months ended March 31,
	2011		2010		$ Change

Currency swaps	$	1,080	$	(1,087)	$	2,167
Foreign currency forward contracts		(2,011)		6,190		(8,201)
Reinsurance derivatives		241		555		(314)
Net realized and unrealized (losses) gains - other	$	(690)	$	5,658	$	(6,348)

·	The net losses associated with the currency swaps and foreign currency forward contracts are due to currency fluctuations which are partially offset by gains recorded through balance sheet currency revaluations and on operational hedges on reinsurance balances.

Interest Expense

Interest expense consists of interest due on outstanding debt securities and the amortization of debt offering expenses. Interest expense was $2.9 million for the three months ended March 31, 2011, compared to $2.5 million for the three months ended March 31, 2010.

Foreign Exchange

For the three months ended March 31, 2011, we experienced net foreign exchange losses of $9.9 million compared to net foreign exchange gains of $4.0 million for the three months ended March 31, 2010. This decrease is primarily due to impact of the weakening U.S. dollar on our liabilities. Net realized and unrealized gains and losses on derivatives used to hedge those balances are included in “Net realized and unrealized gains and losses – other” in the unaudited condensed consolidated statements of operations and comprehensive (loss) income.

Income Tax Expense

We have subsidiaries that operate in various other jurisdictions around the world that are subject to tax in the jurisdictions in which they operate. The significant jurisdictions in which our subsidiaries are subject to tax are South Africa, Canada, India, Switzerland, U.S. Virgin Islands (“USVI”), United Kingdom, and the U.S. However because the majority of our income to date has been earned in Bermuda where we are exempt from income tax, the impact of income taxes to date has been minimal.

During the three months ended March 31, 2011, income tax recovery was $4.6 million compared to income tax expense of $2.9 million for the three months ended March 31, 2010. The change is primarily attributable to the recognition of a deferred tax asset on tax loss carryforward in the U.K and to lower taxable income in tax jurisdictions.

Other		-		(44)
Income attributable to noncontrolling interest	$	824	$	6,046

The portions of Mont Fort’s net income and shareholders’ equity attributable to the preferred shareholders and Island Heritage’s net income and shareholders’ equity attributable to minority shareholders are recorded as noncontrolling interest in accordance with the FASB ASC Topic on Consolidation.

Comprehensive (Loss) Income

The following table is the breakdown of comprehensive (loss) income in the unaudited condensed consolidated statements of operations into its various components:

	For the three months ended March 31,
	2011		2010

Net (loss) income	$	(160,396)	$	37,550
Change in currency translation adjustment		2,877		(3,697)
Change in defined benefit pension plan obligation		-		500
Comprehensive (loss) income		(157,519)		34,353
Less: Comprehensive (income) attributable to noncontrolling interest		(824)		(6,046)
Comprehensive (loss) income attributable to Flagstone	$	(158,343)	$	28,307

The currency translation adjustment is a result of the translation of our foreign subsidiaries into U.S. dollars, net of transactions designated as hedges of net foreign investments. We have entered into certain foreign currency forward contracts that we have designated as hedges in order to hedge our net investment in foreign subsidiaries. To the extent that the contracts are effective as a hedge, both the realized and unrealized gains and losses associated with the designated hedge instruments are recorded in other comprehensive income as part of the cumulative translation adjustment. We designated $45.8 million and $43.2 million of foreign currency forwards contractual value as hedge instruments, which had fair a value of $(0.5) million and $(0.5) million, at March 31, 2011 and December 31, 2010, respectively. We recorded $1.2 million of realized and unrealized foreign exchange losses during the three months ended March 31, 2011 and $0.6 million of realized and unrealized foreign exchange gains during the three months ended March 31, 2010.

Financial Condition, Liquidity, and Capital Resources

Financial Condition

Our investment portfolio on a risk basis, at March 31, 2011, comprised 88.7% fixed maturities, short-term investments and cash and cash equivalents, 5.6% equities and the balance in other investments. We believe that substantially all of our investments can be liquidated and converted into cash within a very short period of time. However, our investment funds, which represent 2.4% of our total investments and cash and cash equivalents at March 31, 2011, do not trade in active markets and are subject to redemption provisions that prevent us from converting them into cash immediately.

At March 31, 2011 and December 31, 2010, all of the fixed maturity securities in our investment portfolio were rated investment-grade (BBB- or higher) by Standard & Poor’s (or an equivalent rating by another rating agency) with an average rating of AA+.

The average duration of our investment portfolio was 2.0 years for both March 31, 2011 and December 31, 2010.

Other investments as at March 31, 2011, amounted to $121.5 million compared to $119.8 million at December 31, 2010. At March 31, 2011, the other investments comprised $72.3 million in catastrophe bonds and $46.3 million in investment funds, which are recorded at fair value and our equity method investment of $2.8 million. The increase in other investments during the first three months of 2011 is principally related to additional investments in investment funds.

Index

The net receivable for investments sold at March 31, 2011, was $56.7 million, compared to a net payable for investments purchased of $1.3 million at December 31, 2010. Net payables and receivables for investments are a result of timing differences only, as investments are accounted for on a trade date basis.

See Note 4 “Investments” to the unaudited condensed consolidated financial statements for further details on amortized cost, gross unrealized gains and losses, and rating and maturity distributions.

Liquidity

Cash flows from operations for the three months ended March 31, 2011 decreased to $42.0 million from $67.5 million as compared to the same period in 2010. This decrease in cash flows from operations was primarily related to lower net income and increased unearned premiums ceded and reinsurance recoverable, partially offset by increased loss and loss adjustment expense reserves. Because a large portion of the coverages we provide can produce losses of high severity and low frequency, it is not possible to accurately predict our future cash flows from operating activities. As a consequence, cash flows from operating activities may fluctuate, perhaps significantly, between individual quarters and years.

Cash flows relating to financing activities include the payment of distributions to shareholders, share related transactions and the issuance or repayment of debt. During the three months ended March 31, 2011, net cash of $49.7 million was used in financing activities, compared to $36.7 million for the same period in 2010. For the three months ended March 31, 2011, the net cash used in financing activities related principally to the redemption of preferred shares in Mont Fort High Layer. For the three months ended March 31, 2010, the net cash used in financing activities related principally to the repurchase of common shares held in treasury.

We may incur additional indebtedness in the future if we determine that it would improve the efficiency of our capital structure.

Generally, positive cash flows from our operating and financing activities are invested in our investment portfolio.

To date, we have had sufficient cash flows from operations to meet our liquidity requirements. We expect that our operational needs for liquidity for at least the next twelve months will be met by our balance of cash, funds generated from underwriting activities, investment income and the proceeds from sales and maturities of our investment portfolio. In the current financial environment, it may be difficult for the insurance industry generally, and us in particular, to raise additional capital when required, on acceptable terms or at all. Cash and cash equivalents were $397.1 million at March 31, 2011.

Capital Resources

Our total capital resources at March 31, 2011 and December 31, 2010 were as follows:

	As at
		March 31, 2011	December 31, 2010

Long term debt	$	252,174	$	251,122
Common shares		845		845
Common shares held in treasury		(162,146)		(178,718)
Additional paid-in capital		880,066		904,235
Accumulated other comprehensive loss		(3,301)		(6,178)
Retained earnings		253,329		414,549
Total capital	$	1,220,967	$	1,385,855

The movement in both common shares held in treasury and additional paid-in capital during the three months ended March 31, 2011, arises from the use of treasury shares to settle fully vested stock based compensation grants.

For the three months ended March 31, 2011, accumulated other comprehensive loss arose from the changes in currency translation adjustment of $2.9 million.

Restrictions and Specific Requirements

Luxembourg

We do not conduct the business of an insurer or reinsurer in Luxembourg and therefore are not required to be registered with the Commissairiat aux Assurances, which is the authority in Luxembourg that regulates insurers and reinsurers.

Under Luxembourg Law, our shareholders may declare dividends at a general meeting of shareholders through the passage of an ordinary resolution, but, in accordance with our Articles, the dividend may not exceed the amount recommended by our Board. Dividends may only be declared from our distributable reserves. In accordance with Luxembourg Law, no distributions to shareholders may be made when, on the closing date of the relevant financial year, the net assets as set out in the annual accounts are, or would be following such a distribution, lower than the subscribed capital plus the reserves that may not be distributed under Luxembourg Law or in accordance with our Articles. The amount of a distribution to shareholders may not exceed the amount of profits at the end of the last financial year plus any profits carried forward and any amounts drawn from reserves which are available for that purpose, less any losses carried forward and sums to be placed to reserve in accordance with the Luxembourg Law or in accordance with the Articles.

Subject to Luxembourg Company Law, our Board may declare interim dividends. The declaration of interim dividends is subject to the approval of shareholders at the next general meeting. Where the payments made on account of interim dividends exceed the amount of dividends subsequently approved by shareholders at the general meeting, they shall, to the extent of the overpayment, be deemed to have been paid on account of the next dividend. Our Articles allow for the declaration of interim dividends, but any payment of interim dividends is subject to the conditions that: (i) interim accounts are drawn up showing that the funds available for distribution are sufficient; (ii) the amount to be distributed may not exceed total profits made since the end of the last financial year for which the accounts have been approved, plus any profits carried forward and sums drawn down from reserves available for this purpose, less losses carried forward any sums to be placed to reserve pursuant to the requirements of the law or our Articles; (iii) the decision of our Board to distribute an interim dividend may not be taken more than two months after the date at which the interim accounts have been made up; (iv) in their report, our Board of Directors and the statutory auditor shall verify whether the above conditions have been satisfied.

Certain of our investment management activities are based in Luxembourg and managed through Flagstone Capital Management Luxembourg SICAF – FIS (“FCML”). FCML is a closed-end investment fund and is regulated by the Luxembourg Commission de Surveillance du Secteur Financier. In accordance with the various documents governing the operation of FCML, a general meeting determines how the profits (including net realized capital gains) of FCML are disposed of and may from time to time declare, or authorize the Board of Directors of FCML to declare dividends, provided however that the capital of FCML including issue premiums does not fall below €1,250,000 or the equivalent thereof in any currency in which shares in FCML are issued. Dividends may also be paid out of net unrealized capital gains after deduction of realized losses. The Board of Directors of FCML is further authorized to pay interim dividends subject to the relevant provisions of Luxembourg law.

Switzerland

Flagstone Suisse is licensed to operate as a reinsurer in Switzerland and Flagstone Suisse is also licensed in Bermuda a branch office. Flagstone Suisse is not licensed in any other jurisdictions. Because many jurisdictions do not permit insurance companies to take credit for reinsurance obtained from unlicensed or non-admitted insurers on their statutory financial statements unless appropriate security mechanisms are in place, we anticipate that our reinsurance clients will typically require Flagstone Suisse to post a letter of credit or other collateral.

Index

Swiss law permits dividends to be declared only after profits have been allocated to the reserves required by law and to any reserves required by the articles of incorporation. The articles of incorporation of Flagstone Suisse do not require any specific reserves. Therefore, Flagstone Suisse must allocate any profits first to the reserve required by Swiss law generally, and may pay as dividends only the balance of the profits remaining after that allocation. In the case of Flagstone Suisse, Swiss law requires that 20% of the company’s profits be allocated to a “general reserve” until the reserve reaches 50% of its paid-in share capital.

In addition, a Swiss reinsurance company may pay a dividend only if, after payment of the dividend, it will continue to comply with regulatory requirements regarding minimum capital, special reserves and solvency.

Bermuda

Flagstone Suisse is licensed as a Class 4 insurer in Bermuda through its branch office. The Bermuda Insurance Act requires Flagstone Suisse to maintain a minimum solvency margin (being the minimum amount that the statutory assets must exceed the statutory liabilities as required by the Bermuda Insurance Act) equal to the greatest of (i) $100 million, (ii) 50% of net premiums written or (iii) 15% of the reserve for losses and loss adjustment expenses.

In addition, each Class 4 insurer must maintain its capital at a level equal to its enhanced capital requirement ("ECR") which is established by reference to the Bermuda Solvency Capital Requirement ("BSCR") model which came into force in 2008 to assist the Bermuda Monetary Authority (the “BMA”) to better assess the adequacy of a Class 4 insurer's capital.

Alternatively, under the Insurance Act, insurers may, subject to the terms of the Insurance Act and to the BMA's oversight, elect to utilize an approved internal capital model to determine regulatory capital. The BMA believes that use of an internal model to substantiate the required regulatory capital requirement may in many circumstances better reflect a specific insurer's particular business profile than a market-wide regulatory model. An insurer's internal model must satisfy certain criteria to be approved for the determination of regulatory capital. In either case, the ECR shall at all times equal or exceed the Class 4 insurer's Minimum Solvency Margin and may be adjusted in circumstances where the BMA concludes that the insurer's risk profile deviates significantly from the assumptions underlying its ECR or the insurer's assessment of its risk management policies and practices used to calculate the ECR applicable to it.

In 2009, the BMA launched its Bermuda Insurance Solvency Framework, which is designed to enable Bermuda to achieve "equivalence" with Solvency II. The impact of this initiative is currently being monitored by the Company.

Bermuda law limits the maximum amount of annual dividends or distributions payable by Flagstone Suisse to the Company and in certain cases requires the prior notification to, or the approval of, the BMA. As a Bermuda Class 4 reinsurer, Flagstone Suisse may not pay dividends in any financial year which would exceed 25% of its total statutory capital and surplus unless at least seven days before payment of those dividends it files an affidavit with the BMA signed by at least two directors and Flagstone Suisse’s principal representative, which states that in their opinion, declaration of those dividends will not cause Flagstone Suisse to fail to meet its prescribed solvency margin and liquidity ratio. Further, Flagstone Suisse may not reduce by 15% or more its total statutory capital as set out in its previous year’s statements, without the prior approval of the BMA. Flagstone Suisse must also maintain, as a Class 4 Bermuda reinsurer, paid-up share capital of $1 million.

Cayman Islands

Island Heritage is domiciled in the Cayman Islands and maintains a Class A Domestic Insurance License issued under the Insurance Law (as revised) of the Cayman Islands. It is thereby subject to regulation by the Cayman Islands Monetary Authority (“CIMA”), which enforces the applicable provisions of the Insurance Law and also the Monetary Authority Law.

A Class “A” Insurer’s license permits an insurer to carry on insurance business generally in or from within the islands. The Insurance Law mandates that changes to the information provided upon application for a license be approved or notified to CIMA, including director and ownership changes and the nature of the business. A relatively low capital requirement is currently prescribed in the Insurance Law, in order to accommodate the large captive insurance market in the Cayman Islands, but CIMA is able to attach conditions to licenses and thereby prescribe an appropriate capital and solvency requirement. A new law was passed in 2010 and is due to come into effect in 2011 pending the finalization of subsidiary legislation. It is expected that the 2010 Law will prescribe a risk based capital requirement comprising a minimum and a prescribed amount, which failure to meet will lead to enforcement and remedial action respectively.

South Africa

Flagstone Africa is licensed to operate as a reinsurer in South Africa and is subject to statutory minimum capital requirements under applicable legislation. In addition, a South African reinsurance company may pay a dividend only if, after payment of the dividend, it will continue to comply with regulatory requirements regarding minimum capital, special reserves and solvency requirements.

Index

United Kingdom
FSML and Syndicate 1861 are regulated by the Financial Services Authority (“FSA”) in the U.K. The FSA is an independent non-governmental body, given statutory powers by the Financial Services and Markets Act 2000. Although accountable to treasury ministers and through them to Parliament, it is funded entirely by the firms it regulates. The FSA has wide ranging powers in relation to rule-making, investigation and enforcement to enable it to meet its four statutory objectives, which are summarized as one overall aim: “to promote efficient, orderly and fair markets and to help retail consumers achieve a fair deal”.

In relation to insurance business, the FSA regulates insurers, insurance intermediaries and Lloyd’s itself. The FSA and Lloyd’s have common objectives in ensuring that Lloyd’s market is appropriately regulated and, to minimize duplication, the FSA has agreed arrangements with Lloyd’s for cooperation on supervision and enforcement.

FSML’s underwriting activities are therefore regulated by the FSA as well as being subject to the Lloyd’s “franchise”. Both FSA and Lloyd’s have powers to remove their respective authorization to manage Lloyd’s syndicates. Lloyd’s approves annually Syndicate 1861’s business plan and any subsequent material changes, and the amount of capital required to support that plan. Lloyd’s may require changes to any business plan presented to it or additional capital to be provided to support the underwriting (known as Funds at Lloyd’s).

Solvency II

The European Parliament passed the Solvency II directive in April 2009, to establish a revised set of European Union (EU) wide capital requirements and risk management standards. All (re)insurers, including Lloyd’s and its managing agents, within the EU need to be compliant with Solvency II by January 1, 2013.

Flagstone’s existing risk management framework and mechanisms, including its compliance with the Swiss Solvency Test, closely mirror the requirements for Solvency II. Since its inception, Flagstone has invested in its internal model that generates the Group’s risk profile and is currently also used to calculate the internal capital requirements for Lloyd’s. Flagstone is working closely with Lloyd’s to ensure full compliance with the regulations. Flagstone believes that Solvency II will have a positive impact on its operations and risk management framework.

Off Balance Sheet Arrangements

Valais Re is a special purpose, exempted company licensed as a restricted Class B reinsurer in the Cayman Islands and formed solely for the purpose of entering into certain reinsurance agreements and other risk transfer agreements with subsidiaries of Flagstone Suisse. During 2008, we entered into a reinsurance agreement with Valais Re that provides us with $104.0 million of aggregate indemnity protection for certain losses from global catastrophe events.

Montana Re is a special purpose reinsurer established in the Cayman Islands and was formed as a program structure enabling further issuance of additional series of notes in the future. During 2009, we entered into a reinsurance agreement with Montana Re that provides us with $175.0 million of protection for certain losses from global catastrophe events. During 2010, we entered into an additional reinsurance agreement with Montana Re, which incepted on January 1, 2011, that provides us with $210.0 million of protection for certain losses from global catastrophe events.

We have determined that Valais Re and Montana Re have the characteristics of a variable interest entity that are addressed by the Consolidation Topic of the FASB ASC. In accordance with the Consolidation Topic, Valais Re and Montana Re are not consolidated because we are not the primary beneficiary.

We are not party to any transaction, agreement or other contractual arrangement to which a Flagstone affiliated unconsolidated entity is a party, other than those noted above with Valais Re and Montana Re, that management believes is reasonably likely to have a current or future effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We measure and manage market risks and other risks as part of an enterprise-wide risk management process. The market risks described in this section relate to financial instruments, primarily in our investment portfolio, that are sensitive to changes in interest rates, credit risk premiums or spreads, foreign exchange rates and equity prices.

We are exposed principally to four types of market risk are: interest rate risk, equity price risk, credit risk and foreign currency risk.

Interest Rate Risk

Our primary market risk exposure is to changes in interest rates. Fluctuations in interest rates have a direct impact on the market valuation of our fixed maturity portfolio. As interest rates rise, the market value of our fixed maturity portfolio falls and there is a risk that cash outflows will have to be funded by selling assets, which will be trading at depreciated values. As interest rates decline, the market value of our fixed maturity portfolio increases and we have reinvestment risk since funds reinvested may earn less than is necessary to match anticipated liabilities. We expect to manage interest rate risk by selecting investments with characteristics such as duration, yield, currency and liquidity which can be tailored to the anticipated cash outflow characteristics of our reinsurance liabilities. In addition, from time-to-time, we may enter into interest rate swap contracts as protection against unexpected shifts in interest rates, which would affect the fair value of the fixed maturity portfolio. By using swaps in the portfolio, the overall duration or interest rate sensitivity of the portfolio can be altered.

As at March 31, 2011, the impact on our fixed maturity securities and cash and cash equivalents, from an immediate 100 basis point increase in market interest rates would have resulted in an estimated decrease in market value of 2.1%, or approximately $31.9 million. As at March 31, 2011, the impact on our fixed maturity securities, cash and cash equivalents, from an immediate 100 basis point decrease in market interest rates would have resulted in an estimated increase in market value of 1.8%, or approximately $27.6 million.

We use interest rate futures to manage the duration of our investment portfolio. As at March 31, 2011, the total exposure of the interest rate futures contracts held was $1.5 billion and these positions had a fair value of $1.7 million. The interest rate futures contracts held were for three month exposure to U.S. and Euro interest rates, and we held short positions which reduced the duration of our portfolio. As at March 31, 2011, the impact of these futures on our fixed maturity securities and cash and cash equivalents was a reduction of duration by 1.0 years. The impact from an immediate 100 basis point increase in market interest rates would have resulted in an estimated increase in market value of the interest rate futures contracts by approximately $15.1 million. The impact from an immediate 100 basis point decrease in market interest rates would have resulted in an estimated decrease in market value of the interest rate futures contracts by approximately $14.3 million.

As at March 31, 2011, we held $293.1 million, or 21.3% of our fixed maturity portfolio in asset-backed and mortgage-backed securities. We did not hold any sub-prime securities at March 31, 2011. These assets are exposed to prepayment risk, which occurs when holders of underlying loans increase the frequency with which they prepay the outstanding principal before the maturity date and refinance at a lower interest rate cost. The adverse impact of prepayment is more evident in a declining interest rate environment. As a result, we would also be exposed to reinvestment risk, as cash flows received by us could be accelerated and would be reinvested at the prevailing interest rates.

Equity Price Risk

We gain exposure to the equity, commodities and real estate markets through the use of various equity and index-linked futures. The total of such exposure as at March 31, 2011 was $139.4 million. The fair value of these positions as at March 31, 2011 amounted to $3.6 million and was recorded in equity investments, other assets and other liabilities. For the three months ended March 31, 2011, we recorded net realized and unrealized gains of $5.1 million in net realized and unrealized gains – investments. The total exposure of the index-linked futures was $139.1 million as at March 31, 2011.

Credit Risk

We have exposure to credit risk primarily as a holder of fixed maturity securities. Our risk management strategy and investment guidelines have been defined to ensure we invest in debt instruments of high credit quality issuers and to limit the amount of credit exposure with respect to particular ratings categories and any one issuer. As at March 31, 2011, our fixed maturity investments consisted of investment grade securities with an average rating of AA+. We believe this high-quality portfolio reduces our exposure to credit risk on fixed income investments to an acceptable level. We have included credit rating information with respect to our investment portfolio because it enhances the reader's understanding of its composition and consistency with our investment philosophy.

Index

To a lesser extent, we also have credit risk exposure as a party to over-the-counter derivative instruments. These derivative instruments include foreign currency forward contracts, currency swaps, total return swaps, and reinsurance derivatives. To mitigate this risk, we monitor our exposure by counterparty and ensure that counterparties to these contracts are high-credit-quality international banks or counterparties.

In addition, we have exposure to credit risk as it relates to our insurance and reinsurance balances receivable. Premium balances receivable from our clients at March 31, 2011 and December 31, 2010, were $438.4 million and $318.5 million, respectively, including balances both currently due and accrued. We believe that credit risk exposure related to these balances is mitigated by several factors, including but not limited to credit checks performed as part of the underwriting process, monitoring of aged receivable balances, our right to cancel the cover for non-payment of premiums, and our right to offset premiums yet to be paid against losses due to the cedent. Since our inception in October 2005, we have recorded $4.1 million in bad debt expenses related to our insurance and reinsurance premium balances receivable.

We purchase retrocessional reinsurance and require our reinsurers to have adequate financial strength or collateralize their exposures. We evaluate the financial condition of our reinsurers and monitor our concentration of credit risk on an ongoing basis.

In addition, consistent with industry practice, we assume a degree of credit risk associated with reinsurance and insurance brokers. We frequently pay amounts owed on claims under our policies to reinsurance brokers, and these brokers, in turn, pay these amounts to the ceding insurers that have reinsured a portion of their liabilities with us. In some jurisdictions, if a broker fails to make such a payment, we may remain liable to the ceding insurer for the deficiency. Conversely, in certain jurisdictions, when the ceding insurer pays premiums to reinsurance brokers for payment to us, these premiums are considered to have been paid and the ceding insurer will no longer be liable to us for those amounts, regardless of whether we have received the premiums.

For risk management purposes, we use catastrophe bonds to manage our reinsurance risk and treat the catastrophe risks related to Catastrophe bonds as part of our underwriting risks. Catastrophe bonds are selected by our reinsurance underwriters however they are held in our investment portfolio as floating rate bonds for performance purposes.

Foreign Currency Risk

We use foreign currency forward contracts and currency swaps to manage currency exposure. The net notional exposure of foreign currency forward contracts in U.S. dollars as at March 31, 2011 and December 31, 2010, were $999.1 million and $854.2 million, respectively, and these contracts had a fair value of $(21.6) million and $(5.2) million, respectively. The change results from an increased allocation to our non-U.S. dollar strategy, which we hedge back to U.S. dollars. For the three months ended March 31, 2011 and 2010, we recorded net realized and unrealized losses of $36.0 million and net realized and unrealized gains of $23.7 million, respectively, on foreign currency forward contracts.

Premiums, Reserves, and Claims

The U.S. dollar is our principal reporting currency and the functional currencies of our operating subsidiaries are generally their national currencies, except for our Bermuda, Cayman Islands, Luxembourg, Gibraltar, FSML subsidiaries and Flagstone Suisse, each of whose functional currency is the U.S. dollar. We enter into reinsurance contracts where the premiums receivable and losses payable are denominated in currencies other than the U.S. dollar. When we incur a loss in a non-U.S. dollar currency, we carry the liability on our books in the original currency. As a result, we have an exposure to foreign currency risk resulting from fluctuations in exchange rates between the time premiums are collected and the time claims are paid.

With respect to loss reserves denominated in non-U.S. dollar currencies, our policy is to hedge the majority of our non-U.S. dollar foreign currency exposure with derivative instruments such as currency swaps and foreign currency forward contracts.

Investments

A large portion of the securities held in our investment portfolios are measured in U.S. dollars, with a portion of our fixed maturities portfolio invested in non-U.S. dollar currencies. At the time of purchase, each investment is identified as either a hedged investment, to be maintained with an appropriate currency hedge to U.S. dollars or an unhedged investment, one not to be maintained with a hedge. Generally, fixed income investments will be hedged, listed equity investments may or may not be hedged, and other investments such as investment funds may or may not be hedged.

Index

Financing

Certain subsidiaries of ours have a functional currency other than the U.S. dollar. Our practice is to hedge the net investment in those subsidiaries and designate foreign currency forward contracts as hedging instruments. The contractual amount of these contracts as at March 31, 2011 and December 31, 2010 was $45.8 million and $43.2 million, respectively, and the contracts had a fair value of $(0.5) million and $(0.5) million, respectively. During the three months ended March 31, 2011 and 2010, we recorded net realized and unrealized losses of $1.2 million and net realized and unrealized gains of $0.6 million, respectively, directly into comprehensive income as part of the cumulative translation adjustment for the effective portion of the hedge.

We entered into a currency swap agreement to hedge the Euro-denominated deferrable interest debentures recorded as long term debt. Under the terms of the foreign currency swap, we exchanged €13.0 million for $18.4 million, and will receive Euribor plus 354 basis points and pay LIBOR plus 367 basis points. The swap expires on September 15, 2011 and had a fair value of less than $0.1 million as at March 31, 2011.

Foreign currency exchange contracts will not eliminate fluctuations in the value of our assets and liabilities denominated in foreign currencies but rather allow us to establish a rate of exchange for a future point in time. Of our business written in the three months ended March 31, 2011 and 2010, approximately 46.8% and 40.8%, respectively, was written in currencies other than the U.S. dollar. For the three months ended March 31, 2011, we had net foreign exchange losses of $9.9 million compared to gains of $4.0 million for the same period in 2010.

We do not hedge currencies for which our asset or liability exposures are not material or where we are unable or it is impractical to do so. In such cases, we are exposed to foreign currency risk. However, we do not believe that the foreign currency risks corresponding to these unhedged positions are material.

Effects of Inflation

We do not believe that inflation has had a material effect on our consolidated results of operations, except insofar as (a) inflation may affect interest rates, and (b) losses and loss expenses may be affected by inflation.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report, including the documents we incorporate by reference, contains, and the Company may from time to time make, written or oral “forward-looking statements” within the meaning of the U.S. Federal securities laws, which are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. All forward-looking statements rely on a number of assumptions concerning future events and are subject to a number of uncertainties and other factors, many of which are outside the Company’s control that could cause actual results to differ materially from such statements. In particular, statements using words such as “may”, “should”, “estimate”, “expect”, “anticipate”, “intend”, “believe”, “predict”, “potential”, or words of similar import generally involve forward-looking statements.

Important events and uncertainties that could cause the actual results to differ include, but are not necessarily limited to: market conditions affecting our common share price; the possibility of severe or unanticipated losses from natural or man-made catastrophes; the effectiveness of our loss limitation methods; our dependence on principal employees; the cyclical nature of the insurance and reinsurance business; the levels of new and renewal business achieved; opportunities to increase writings in our core property and specialty reinsurance and insurance lines of business and in specific areas of the casualty reinsurance market; the sensitivity of our business to financial strength ratings established by independent rating agencies; our ability to raise capital on favorable terms or at all; the estimates reported by cedents and brokers on pro-rata contracts and certain excess of loss contracts in which the deposit premium is not specified; the inherent uncertainties of establishing reserves for loss and loss adjustment expenses, and our reliance on industry loss estimates and those generated by modeling techniques; unanticipated adjustments to premium estimates; changes in the availability, cost or quality of reinsurance or retrocessional coverage; our exposure to many different counterparties in the financial service industry, and the related credit risk of counterparty default; changes in general economic conditions; changes in governmental regulation or tax laws in the jurisdictions where we conduct business; the amount and timing of reinsurance recoverables and reimbursements we actually receive from our reinsurers; the overall level of competition, and the related demand and supply dynamics in our markets relating to growing capital levels in the insurance and reinsurance industries; declining demand due to increased retentions by cedents and other factors; the impact of terrorist activities on the economy; and rating agency policies and practices.
