SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS
1. Organization
On March 17, 2006, XL Capital Ltd (XL Capital) formed Security Capital Assurance Ltd (SCA), as a wholly owned Bermuda based subsidiary holding company. On July 1, 2006, XL Capital
  contributed all its ownership interests in its financial guarantee insurance and financial guarantee reinsurance operating businesses to SCA. The aforementioned operating businesses consisted of: (i)
  XL Capital Assurance Inc. (XLCA) and its wholly-owned subsidiary, XL Capital Assurance (U.K.) Limited (XLCA-UK) and (ii) XL Financial Assurance Ltd. (XLFA). XLCA was an indirect
  wholly owned subsidiary of XL Capital and all of XLFA was owned by XL Capital except for a preferred stock interest which is owned by Financial Security Assurance Holdings Ltd. (FSAH), an
  entity which is otherwise not related to XL Capital or SCA. SCA, XLCA, XLFA and all other subsidiaries of SCA are hereafter collectively referred to as the Company.
On August 4, 2006, SCA completed the sale of 18,009,119 of its common shares through an initial public offering (the IPO). SCA received net proceeds from the IPO of $341.3 million. In
  addition, XL Capital sold 5,430,774 of SCAs common shares (including 992,165 common shares pursuant to the exercise of an over-allotment option granted to underwriters) from its holdings directly
  to the public in a secondary offering concurrent with the IPO. SCA did not receive any of the proceeds from the aforementioned sale by XL Capital. Immediately after the IPO and the secondary
  offering, XL Capital owned 40,696,471 SCA common shares, which represented approximately a 63 percent economic interest in SCA, adjusted for restricted share awards to the Companys employees
  and management granted at the effective date of the IPO. In June 2007, XL Capital completed the sale of an additional 10,627,422 common shares of SCA from its holdings (including 947,400
  common shares pursuant to the exercise of an over-allotment option granted to underwriters). SCA did not receive any of the proceeds from this sale. Immediately after such sale XL Capital owned
  30,069,049 common shares of SCA, which represented approximately a 46 percent voting and economic interest in SCA, adjusted for restricted share awards to the Companys employees and
  management outstanding as of such date. Prior to XL Capitals sale of SCA common shares in June 2007 its voting interest in SCA was subject to limitations contained in our bye-laws.
2. Basis of Presentation and Consolidation
The unaudited interim consolidated financial statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States of America
  (GAAP) and, in the opinion of management, reflect all adjustments, consisting of normally recurring adjustments, necessary for a fair presentation of the Companys consolidated financial condition,
  results of operations and cash flows for the periods presented, including the elimination of all significant inter-company accounts and transactions. In addition, certain reclassifications have been made
  to prior period consolidated financial statement amounts to conform to current year presentation. There was no effect on prior period reported net income as a result of these reclassifications.
Interim consolidated financial statements do not include all of the information and footnotes required by GAAP for annual financial statements. In addition, the year-end balance sheet data was
  derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. The preparation of financial
  statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and
  liabilities as of 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. In addition, the
  results of operations for the interim periods ended September 30, 2007 are not necessarily indicative of the results that may be expected for the year ended December 31, 2007. These interim
  consolidated financial statements of the Company should be read in conjunction with the annual audited consolidated financial statements of the Company as of December 31, 2006 and 2005 and for
  the years ended December 31, 2006, 2005, and 2004 included in the Companys
7

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
Annual Report on Form 10-K, which was filed with the Securities and Exchange Commission on March 15, 2007.
For the three and nine month periods ended September 30, 2006, certain expenses reflected in the financial statements include allocations of expenses by XL Capital related to general and
  administrative services provided to the Company. These expenses were allocated based on estimates of the cost incurred by XL Capital to provide these services to the Company. Management
  believes that the methods used to estimate the costs allocated to the Company are reasonable. However, these results do not necessarily represent what the historical consolidated financial position,
  results of operations and cash flows would have been if the Company had been a separate stand-alone entity during such periods.
3. Derivative Financial Instruments
The Company issues and reinsures credit default swap contracts and certain other credit derivatives. Under the terms of its credit default swap contracts the Company is generally required to
  make payments to its counterparty in the event of specific credit events relating to assets referenced in the contracts after exhaustion of various first-loss protection levels. These credit events are
  contract-specific, but generally cover bankruptcy and failure to pay. These credit derivatives are not subject to collateral or margin requirements. Accordingly, the credit default swap contracts
  function like the guarantees of debt obligations that the Company provides in the form of insurance.
Assets referenced in the Companys in-force credit default swap contracts consist of structured pools of corporate obligations. Such pools were awarded investment-grade ratings at the deals
  inception. At September 30, 2007, the notional amount outstanding of the Companys in-force credit default swap contracts was $52.4 billion ($49.2 billion net of reinsurance) and the weighted
  average term of such contracts was 8.3 years. In addition, based on such notional amount, as of September 30, 2007 approximately 95.6% of referenced assets underlying such in-force contracts were
  rated (based on Standard & Poors ratings) AAA, with the remaining 4.4% rated at or above investment-grade.
The Companys policy is to hold its credit default swap contracts to maturity and not to trade such contracts to realize gains or losses from periodic market fluctuations. However, in certain
  circumstances, we may choose to terminate a credit derivative prior to maturity for risk management or other purposes (for example, upon a deterioration in underlying credit quality). With the
  exception of two transactions which occurred in 2004 and 2003, respectively, there have been no such terminations since the Companys inception.
As derivative financial instruments, credit default swap contracts are required to be reported at fair value in accordance with GAAP, with changes in fair value during the period included in
  earnings. The principal drivers of the fair value of the Companys credit default swap contracts include: (i) general market credit spreads for the type(s) of assets referenced in credit default swap
  contracts, (ii) the specific quality and performance of the actual assets referenced in the contracts, (iii) the amount of subordination in the transaction before liability attaches, (iv) the quality of the
  asset manager of the transaction, if applicable, (v) other customized structural features of such contracts (e.g. terms, conditions, covenants), (vi) the rating agency capital charge for the transaction,
  and (vii) supply and demand factors, including the volume of new issuance and financial guarantee market penetration, as well as the level of competition in the marketplace.
The fair value of the Companys in-force portfolio of credit default swap contracts represents managements estimate of the premium that would be required by a market participant to assume
  the risks in the Companys credit derivative portfolio as of the measurement date. Fair value is defined as the price at which an asset or a liability could be bought or transferred in a current
  transaction between willing parties. Fair value is determined based on quoted market prices, if available. If quoted market prices are not available, fair value is estimated based on the use of
  valuation techniques involving management judgment. There are no observable readily available quoted market prices for most of the Companys in-force guarantees under its credit default swap
  contracts since these contracts are generally
8

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
not traded by market participants. Accordingly, the Companys estimate of the fair value of its in-force credit default swap contracts is based on the use of valuation techniques involving management
  judgment, which considers a number of factors, including: (i) credit price indices, published by non-affiliated financial institutions, for the type(s) of assets referenced in the Companys credit default
  swap contracts (both in terms of type of assets and their credit rating), (ii) estimates of rates of return that would be required by a counterparty to assume the risks in the Companys contracts in the
  current market environment, (iii) the quality of the specific assets referenced in the Companys credit default swap contracts at the measurement date, (iv) the market perception of risk associated
  with such asset classes, (v) the amount of subordination in the transactions before the Companys liability attaches relative to that required for similarly rated transactions in the current environment,
  (vi) the remaining average life of the transaction, and (vii) prices of guarantees executed by the Company in its retail market in proximity to the measurement date. Because it is the Companys
  policy to consider all available relevant evidence in forming its best estimate of the fair value of the Companys credit default swaps, as new information becomes available the Company may consider
  new or different factors than those listed above and change its estimates in the future.
The weight ascribed by management to the aforementioned factors in forming its best estimate of the fair value of the Companys credit default swap contracts may vary under changing
  circumstances. In periods prior to September 30, 2007, management principally considered price indices published by non-affiliated financial institutions in forming its best estimate of the fair value of
  the Companys credit default swap contracts. The fair value of the guarantee was determined by multiplying the percentage change in the applicable credit price index or indices applicable to the
  assets referenced in the credit default swap by the present value of the remaining expected future premiums to be received under the contract. Management concluded that results from this
  calculation represented a reasonable estimate of the fair value of the Companys credit default swap contracts at that time.
In forming its best estimate of the fair value of the Companys credit default swap contracts as of September 30, 2007, however, management concluded that, for the majority of the Companys
  credit defaults swap contracts, limited reliance could be placed on published credit price indices because events and conditions in the credit markets associated with subprime mortgage collateral and
  corporate loans resulted in limited transaction activity in many financial instruments during the period (including collateralized debt obligations (CDOs) of high grade asset-backed securities,
  collateralized loan obligations, residential mortgage-backed securities, and CDOs of CDOs), causing financial institutions which publish the indices that management historically relied upon to estimate
  the fair value of the Companys credit derivatives either to refrain from updating such indices or base changes in the indices partly on judgments in regard to estimated price levels and not actual
  executed trades. In addition, evidence suggested that the limited price information available in the marketplace in regard to such instruments was influenced by trades resulting from margin calls and
  liquidity issues that are not part of the risks associated with the Companys business model or credit default swap contracts. Accordingly, managements estimate of the fair value of the Companys
  credit default swap contracts as of September 30, 2007 ascribed significant weight to managements judgments regarding rates of return that would be required by a counterparty to assume the risks in
  the Companys contracts in the current market environment. Managements judgment in regard to such rates of return considered all the factors discussed above. The Companys estimate of fair value
  for the aforementioned financial instruments as of September 30, 2007 was calculated by adjusting the present value of the expected remaining future net cash flows under such contracts (which are
  comprised of the remaining expected future premiums to be received under the contract, less estimated maintenance expenses and a provision for expected losses that will manifest in the future) to
  reflect managements best estimate of the rates of return that would be required by a counterparty to assume the risks on such contracts.
Present values of the cash flows referred to above were determined using a discount rate of 6.0%, which reflects the weighted average life of our in-force credit default swaps and the corporate
  credit rating of the issuer/reinsurer of such contracts, XLCA and XLFA, respectively, at September 30, 2007.

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
Because management views the credit derivative contracts that the Company issues and reinsures as an extension of the Companys financial guarantee business, management believes that the
  most meaningful presentation of these derivatives is to reflect: (i) fees that the Company receives from the issuance of such contracts in the line item captions in the statement of operations entitled
  gross premiums written, reinsurance premium assumed, net premiums written and net premiums earned, as appropriate, (ii) losses from actual and expected payments to counterparties under
  such contracts in the line item caption in the statement of operations entitled net losses and loss adjustment expenses and (iii) changes in the fair value of such instruments which are attributable to
  market factors in the line item caption in the statement of operations entitled net unrealized losses on credit derivatives.

Proposed Statement of Financial Accounting Standards (SFAS), Accounting for Financial Guarantee Insurance Contracts
On April 18, 2007, the Financial Accounting Standards Board (FASB) issued Proposed SFAS, Accounting for Financial Guarantee Insurance Contracts  an interpretation of FASB Statement
  No. 60 (SFAS 60). This proposed Statement would clarify how SFAS 60, Accounting and Reporting by Insurance Enterprises, applies to financial guarantee insurance contracts. This proposed
  Statement, among other things, would change current industry practices with respect to the recognition of premium revenue and claim liabilities. In addition, this proposed Statement would require
  that the measurement of the initial deferred premium revenue (liability) be the present value of the contractual premium due pursuant to the terms of the financial guarantee insurance contract,
  thereby changing current industry accounting practice with respect to insurance contracts priced on an installment basis by requiring that the present value of all contractual premiums due under such
  contracts, currently or in the future, be recorded on the companys balance sheet as premiums receivable. Under current industry practice such premiums are not reflected on the balance sheet.
In regard to premium revenue recognition, the proposed Statement provides for premium to be recognized as revenue, for both upfront and installment paying policies, in proportion to the
  insured contractual principal and interest payments made by the issuer of the insured financial obligation, rather than being recognized over the term of each maturity for upfront premium paying
  policies, or over the installment period for installment premium paying policies. This change would generally result in a
10

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
volatile revenue recognition pattern over the life of the insured obligation as premium would only be recognized as the insured obligations principal or interest is paid. Furthermore, for certain bonds
  such as investor-owned utilities, CDOs and many other types of asset-backed securities that do not have periodic payments, this change would result in significantly slower and back-ended revenue
  recognition. The volatility would be most evident for insured securities whereby the principal payments are made at maturity, but would also impact public finance insured securities with customized
  amortization schedules. For installment paying policies, the proposed Statement requires that the discount, equating to the difference between gross installment premiums and the present value of
  installment premiums, be recognized as investment income rather than premiums. We expect that the initial effect of applying the revenue recognition provisions of the Statement as currently
  proposed will be material to the Companys financial statements.
In regard to the recognition of claim liabilities, the proposed Statement provides that claim liabilities shall be established when the insurance enterprise expects that a claim loss will exceed the
  deferred premium revenue (liability) for a contract based on expected cash flows discounted using a risk-adjusted rate at initial recognition of the claim liability and, that, the assumptions underlying
  such liability be consistent with the information tracked and monitored through the Companys surveillance list maintained to evaluate credit deterioration in its insured financial obligations. We
  expect that implementation of this guidance as currently proposed would cause the Company to de-recognize its reserves for unallocated losses and loss adjustment expenses and preclude it from
  providing such reserves in the future.
The comment period for the proposed Statement expired on June 18, 2007. A meeting between the FASB and interested parties who provided comments on the proposed Statement occurred in
  September 2007. Since the meeting, the FASB Staff has continued to deliberate the matters raised in the comment letters and at the meeting. Currently the proposed Statement is due to be effective
  for fiscal years beginning after December 15, 2007. The Company is continuing to evaluate the effect of the proposed Statement on its financial statements.
SFAS No. 155, Accounting for Certain Hybrid Financial Instruments
In February 2006, the FASB issued SFAS No. 155, Accounting for Certain Hybrid Financial Instruments (SFAS 155), which amends SFAS No. 133, Accounting for Derivative Instruments
  and Hedging Activities (SFAS 133) and SFAS No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities (SFAS 140), and addresses issues raised
  in SFAS 133 Implementation Issue No. D1, Application of Statement 133 to Beneficial Interests in Securitized Financial Assets. The primary objectives of SFAS 155 are: (i) with respect to SFAS
  133, to address the accounting for beneficial interests in securitized financial assets and (ii) with respect to SFAS 140, to eliminate a restriction on the passive derivative instruments that a qualifying
  special purpose entity may hold. SFAS 155 is effective for all financial instruments acquired or issued after the beginning of an entitys first fiscal year that begins after September 15, 2006. The
  Company adopted SFAS 155 on January 1, 2007 and it has had no effect on the Companys financial condition or results of operations.
FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes  an interpretation of FASB Statement No. 109
In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes  an interpretation of FASB Statement No. 109 (FIN 48). FIN 48 prescribes a
  recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, and also provides guidance on
  de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company
  adopted FIN 48 on January 1, 2007 and it has not had any effect on the Companys financial condition or results of operations.
11

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
SFAS No. 157, Fair Value Measurements
In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (SFAS 157) which defines fair value, establishes a framework for measuring fair value in generally accepted
  accounting principles, and expands disclosures about fair value measurements. This Statement is applicable in conjunction with other accounting pronouncements that require or permit fair value
  measurements, where the FASB previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, this Statement does not require any new
  fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within these fiscal years. The Company is
  currently evaluating the effect the adoption of SFAS 157 will have on its financial statements.
SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities
In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS 159). SFAS 159 provides the Company an irrevocable option
  to report selected financial assets and liabilities at fair value with changes in fair value recorded in earnings. The option is applied, on a contract-by-contract basis, to an entire contract and not only
  to specific risks, specific cash flows or other portions of that contract. Upfront costs and fees related to a contract for which the fair value option is elected shall be recognized in earnings as incurred
  and not deferred. SFAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar
  types of assets and liabilities. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the effect, if any, the adoption of SFAS 159 will have on
  its financial statements.
Proposed FASB Staff Position EITF 03-6-a, Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities
In October 2006, the FASB issued proposed FASB Staff Position EITF 03-6-a, Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities.
  This FASB Staff Position (FSP) addresses whether instruments granted in share-based payment transactions may be participating securities prior to vesting and, therefore, need to be included in the
  earnings allocation in computing basic earnings per share (EPS) pursuant to the two-class method described in paragraphs 60 and 61 of FASB Statement No. 128, Earnings Per Share. A share-
  based payment award that contains a non-forfeitable right to receive cash when dividends are paid to common shareholders irrespective of whether that award ultimately vests or remains unvested
  shall be considered a participating security as these rights to dividends provide a non-contingent transfer of value to the holder of the share-based payment award. Accordingly, these awards should be
  included in the computation of basic EPS pursuant to the two-class method. The guidance in this proposed FSP would be effective in the first reporting period beginning after the FASB posts the
  final FSP to its website. All prior period EPS data will have to be adjusted retrospectively to reflect the provisions of the FSP. Under the terms of the Companys restricted stock awards, grantees are
  entitled to the right to receive dividends on the unvested portions of their awards. There is no requirement to return these dividends in the event the unvested awards are forfeited in the future.
  Accordingly, this FSP will have an effect on the Companys EPS calculations should the FASB adopt the proposed guidance during 2007. The Company will continue to evaluate the effect of this
  guidance.
5. Premiums Earned from Refunded Bonds and Other Accelerations
When an insured issue is retired early, is called by the issuer or is in substance paid in advance through a refunding accomplished by placing U.S. Government securities in escrow, the remaining
  deferred premium revenue is earned at that time. Net premiums earned include $5.0 million and $12.0 million, and $0.4 million and $25.6 million for the three and nine months ended September 30,
  2007 and 2006, respectively, related to such refunded bonds and other accelerations.

6. Related Party Transactions
Concurrent with the IPO, the Company entered into arrangements with affiliates of XL Capital: (i) to provide it protection with respect to adverse development on certain transactions, (ii) to
  have exposures transferred to it or re-assume exposures under certain financial guarantee policies that were originally reinsured to, or written on behalf of, the Company by XL Insurance (Bermuda)
  Ltd (XLI), an indirect wholly owned subsidiary of XL Capital, due principally to single risk constraints and rating agency capital adequacy requirements applicable to the Company at the time that
  business was first written, (iii) to cancel the Companys reinsurance of certain non-financial guarantee business ceded to it by XLI, and (iv) to govern certain aspects of Companys relationship with
  XL Capital after the IPO, including a series of service agreements under which subsidiaries of XL Capital will provide certain services to the Company or receive certain services from the Company
  for a period of time after the IPO. The aforementioned arrangements are discussed further below.
In addition, in connection with the IPO, XL Capital agreed to fund a portion of long-term compensation awarded by XL Capital to employees of SCA prior to the IPO and which remained
  outstanding under XL Capitals long-term compensation plans subsequent to the IPO. In this regard, SCA reflects the full cost of the periodic charges from such long-term compensation in its
  earnings each period, XL Capital charges approximately 60% of such cost to SCA, and SCA records a capital contribution from XL Capital equal to the remaining 40% of such cost. The aggregate
  remaining future cost of such long-term compensation to SCA is approximately $1.0 million at September 30, 2007, of which SCA will pay XL Capital approximately $0.6 million and XL Capital will
  fund $0.4 million. During the three and nine months ended September 30, 2007, respectively, the Company recorded compensation expense related to such awards of $0.2 million and $0.7 million,
  respectively.
Services Agreements with Affiliates
Prior to the IPO, the Company purchased certain services from affiliates of XL Capital under various agreements and continued to purchase such services under new agreements that became
  effective at the date of the IPO. Such services principally included: (i) information technology support, (ii) reinsurance and retrocessional consulting and management services, (iii) actuarial, finance,
  legal, internal audit services and certain investment management services. Since the IPO, the Company has undertaken to perform certain of the services itself or to outsource such services to other
  vendors and has, accordingly, discontinued the purchase of many of the services that were provided by XL Capital. For the three and nine months ended September 30, 2007 and 2006, the Company
  incurred costs under the aforementioned agreements aggregating $0.9 million and $3.0 million, and $1.2 million and $5.9 million, respectively, which are reflected in operating expenses in the
  accompanying consolidated statements of operations.
Employee Benefit Plans
The Company maintains a qualified defined contribution pension plan for the benefit of all eligible employees and a non-qualified deferred compensation plan for the benefit of certain employees
  (collectively, the SCA Plans). Prior to the IPO, XL America, Inc (XLA) maintained plans, with substantially the same terms, which employees of the Company participated in (the XLA Plans).
  Discretionary contributions to the SCA Plans and XLA Plans are based on a fixed percentage of employee contributions and compensation, as defined in the aforementioned plans. For the three and
  nine months ended September 30, 2007 and 2006, the Company incurred costs under the aforementioned plans aggregating $1.6 million and $5.0 million, and $0.7 million and $2.0 million, respectively,
  which are reflected in operating expenses in the accompanying consolidated statements of operations.
Reinsurance Agreements and Other Guarantees with Affiliates
The Company has the following reinsurance agreements with affiliates. Certain of the agreements discussed below may be terminated under certain conditions, as defined in the agreements.
13

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)

    
    
    
    Effective July 1, 2007, XLFA ceded certain business to XLI, aggregating approximately $3.7 billion of guaranteed par/notional exposure, under an existing facultative quota share reinsurance
      agreement. As a result of this transaction, on such date, XLFA ceded premiums of $16.3 million to XLI, received a ceding commission allowance of $6.6 million from XLI, and recorded a
      liability to XLI of $9.7 million. The effect on the Companys results of operations for the three and nine month periods ended September 30, 2007 from the subject business was not material.
    
    
    
    Effective August 4, 2006, certain subsidiaries of XL Capital indemnified the Company for all losses and loss adjustment expenses incurred in excess of its retained reserves at the effective date
      of the agreement relating to an insured project financing described in Note 9 (a). In consideration for the aforementioned indemnifications the Company is obligated to pay such affiliates
      approximately $9.8 million on an installment basis over the life of the aforementioned project financing. As this premium is due irrespective of any early termination of the underlying insurance
      transaction, the Company recorded a liability of approximately $7.0 million at the effective date of the indemnifications (representing the present value of the obligation discounted at 5.0%,
      which reflects the rate on treasury obligations with a term to maturity commensurate with that of the liability) and a corresponding deferred cost, which are reflected in the accompanying
      consolidated balance sheets in reinsurance premiums payable and prepaid reinsurance premiums, respectively. For the three and nine months ended September 30, 2007, the Company
      incurred costs under the aforementioned agreements aggregating approximately $0.2 million and $0.6 million and the balance of the aforementioned liability and deferred cost was $6.3 million
      at September 30, 2007.
    
    
    
    Effective August 4, 2006, XLA has undertaken to indemnify the Company for any diminution in value below their carrying value at September 30, 2006 of the notes and preferred shares
      described in Note 9, which notes and preferred shares were acquired in connection with the satisfaction of a claim under a financial guarantee insurance policy issued by XLCA. In addition,
      pursuant to the aforementioned indemnity, XLA agreed to indemnify the Company for any costs arising out of any litigation or future claim in connection with the aforementioned insurance
      policy. See Note 9 for further information regarding amounts recovered or recoverable by SCA under the indemnity.
    
    
    
    On August 4, 2006, XLFA terminated a facultative quota share reinsurance treaty with XLI that had been effective since 2001. As a result of the termination, XLI returned $26.5 million of
      premiums to XLFA, XLFA returned ceding commissions of $7.8 million to XLI, and XLI paid XLFA $18.7 million. The effect on the Companys results of operations for the three and nine
      month periods ended September 30, 2007 and 2006 from the subject business was not material.
    
    
    
    On August 4, 2006, XLFA and XLI agreed to cancel from inception the reinsurance of certain business ceded under a facultative quota share reinsurance treaty that was effective since 1999.
      As a result of this cancellation, XLFA paid XLI $0.2 million, XLI assumed XLFAs obligation for $1.2 million of reserves for losses and loss adjustment expenses, and XLFA recorded a capital
      contribution of $1.0 million. In addition, on such date, XLFA assumed certain business from XLI pursuant to the aforementioned reinsurance treaty. As a result thereof, XLFA recorded
      assumed premiums of approximately $8.0 million, ceding commissions of approximately $1.0 million and received cash from XLI of approximately $7.0 million. There was no effect on the
      Companys results of operations from this transaction for the three and nine months ended September 30, 2007 and the effect on the Companys results of operations from the subject business
      for the three and nine month periods ended September 30, 2006 was not material.
    
    
    
    Effective October 1, 2001, XLFA entered into an excess of loss reinsurance agreement with XLI. This agreement covers a portion of XLFAs liability arising as a result of losses on policies
      written by XLFA that are in excess of certain limits and are not covered by other reinsurance agreements. This agreement provides indemnification only for the portion of any loss covered by
      this agreement in excess of 10% of XLFAs surplus, up to an aggregate amount of $500 million, and excludes coverage for liabilities arising other than pursuant to the terms of an underlying
      policy. The14

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
Company incurred expense under this agreement of approximately $0.1 million and $0.4 million, and $0.1 million, and $0.4 million for the three and nine month periods ended September 30,
      2007 and 2006, respectively.
    
    
    
    Effective November 1, 2002, XLCA entered into a facultative reinsurance arrangement (the XL Re Treaty) with XL Reinsurance America, Inc. (XL RE AM). Under the terms of the XL Re
      Treaty, XL RE AM agrees to reinsure risks insured by XLCA under financial guarantee insurance policies up to the amount necessary for XLCA to comply with single risk limitations set forth
      in Section 6904(d) of the New York Insurance Laws. Such reinsurance was on an automatic basis prior to the effective date of the IPO and is on a facultative basis on and after the effective
      date of the IPO. The reinsurance provided by XL RE AM may be on an excess of loss or quota share basis. The Company is allowed up to a 30% ceding commission (or such other
      percentage on an arms-length basis) on ceded premiums written under the terms of this agreement.
    
    
    
    Since it commenced operations, XLFA has entered into several reinsurance arrangements with subsidiaries and affiliates of FSAH (hereafter referred to as FSA) to reinsure certain policies
      issued by FSA which guarantee the timely payment of the principal of and interest on various types of debt obligations. XLFAs obligations under certain of these arrangements are guaranteed
      by XLI. Effective upon the IPO, the guarantee was terminated with respect to all new business assumed by XLFA under such arrangement, but the guarantee remains in effect with respect to
      cessions under the agreement prior to the IPO. Premiums assumed by XLFA under its reinsurance arrangements with FSA represented 86.7% and 80.1%, and 55.2% and 52.0% of the
      Companys total reinsurance premiums assumed for the three and nine months ended September 30, 2007 and 2006, respectively.
    
    
    
    XLFA has guaranteed certain of XLIs obligations in connection with certain transactions where XLIs customer required such credit enhancement. Each of these transactions has a double
      trigger structure, meaning that XLFA does not have to pay a claim unless both the underlying transaction and XLI default. For each of these transactions, XLFA has entered into a
      reimbursement agreement with XLI, pursuant to which XLI pays XLFA a fee for providing its guarantee and XLI grants XLFA a security interest in a portion of the payments received by it
      from its client. As of September 30, 2007 and December 31, 2006, XLFAs aggregate net par outstanding relating to such guarantees was $522.8 million.
    
    
    
    Effective May 1, 2004, XLI entered into an agreement with XLCA which unconditionally and irrevocably guarantees to XLCA the full and complete payment when due of all of XLFAs
      obligations under its facultative quota share reinsurance agreement with XLCA, under which agreement XLFA has assumed business from XLCA since December 19, 2000. The gross par value of
      business guaranteed by XLI under this agreement was approximately $80.5 billion and $83.1 billion as of September 30, 2007 and December 31, 2006, respectively. The XLI guarantee agreement
      terminated with respect to any new business produced by XLCA and ceded to XLFA pursuant to the facultative quota share reinsurance agreement after the effective date of the IPO, but the
      guarantee remains in effect with respect to cessions under such agreement prior to the IPO.
    
    
    
    The Company provides financial guarantee insurance policies insuring timely payment of investment agreements issued by XL Asset Funding Company I LLC (XLAF), an affiliate of the
      Company. As of September 30, 2007 and December 31, 2006, the aggregate face amount of such investment agreements insured by the Company was $4.8 billion and $3.9 billion, respectively.
      In addition, the Company insures XLAFs obligations under certain derivative contracts issued and purchased by XLAF. As of September 30, 2007, the total notional value of such contracts
      insured was $167.7 million. The Company recorded earned premiums of $1.4 million and $3.4 million, and $1.0 million and $2.9 million, respectively, in each of the three and nine month
      periods ended September 30, 2007 and 2006, relating to the aforementioned contracts.15

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
Other Matters
In connection with the secondary offering of SCA common shares by XL Capital in June 2007 (see Note 1), SCA was obligated, pursuant to registration rights granted to XL Capital in
  connection with the IPO, to pay certain offering costs of up to five secondary offerings of SCA common shares by XL Capital (of at least $50 million in value unless XL Capital holds less than such
  amount at the time of its exercise of registration rights), not including the secondary offering completed by XL Capital concurrent with the IPO. Accordingly, as a result of the secondary offering
  completed in June 2007, the Company incurred expenses of approximately $0.8 million, which are reflected in operating expenses in the Companys consolidated results of operations for the nine
  months ended September 30, 2007. As of September 30, 2007, SCA is obligated to pay offering costs in connection with XL Capitals sale of its SCA common share holdings in up to four more
  offerings of such shares.
7. Income Taxes
XLFA is not subject to any taxes in Bermuda on either income or capital gains under current Bermuda law. In the event that there is a change such that these taxes are imposed, XLFA would
  be exempted from any such tax until March 2016 pursuant to the Bermuda Exempted Undertakings Tax Protection Act of 1966, and Amended Act of 1987.
XLCA is subject to federal, state and local corporate income taxes and other taxes applicable to U.S. corporations. The U.S. federal income tax liability is determined in accordance with the
  principles of the consolidated tax provisions of the Internal Revenue Code and Regulations. XLCA has subsidiary and branch operations in certain international jurisdictions that are subject to
  relevant taxes in those jurisdictions.
XLCA files a consolidated tax return with SCA Holdings U.S. Inc. (the U.S. common parent of the SCA group) and its subsidiaries (which consists of XLCA and SCAs other U.S. based
  subsidiaries). XLCA maintains a tax sharing agreement with its subsidiaries, whereby the consolidated income tax liability is allocated among affiliates in the ratio that each affiliates separate return
  liability bears to the sum of the separate return liabilities of all affiliates that are members of the consolidated group. In addition, a complementary method is used which results in reimbursement by
  profitable affiliates to loss affiliates for tax benefits generated by loss affiliates. As of September 30, 2007 and December 31, 2006, the Company had a U.S. federal income tax payable of $3.3 million
  and $5.3 million, respectively.
As of September 30, 2007 and December 31, 2006, the Company had deferred income tax assets of $28.2 million and $18.2 million, respectively. Such deferred tax assets were net of a valuation
  allowance of $1.5 million and $1.9 million as of September 30, 2007 and December 31, 2006, respectively. The valuation allowance relates to net unrealized capital losses and a net realized capital loss
  that may not be realized within a reasonable period. At September 30, 2007, the Company had net unrealized capital losses and a net realized capital loss carry forward of approximately $2.4 million
  and $1.9 million against which valuation allowances have been established.
The Company adopted the provisions of FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, on January 1, 2007. The Company did not recognize any liabilities for
  unrecognized tax benefits as a result of the implementation of Interpretation 48.
With few exceptions, the Company is no longer subject to tax examinations by tax authorities in the major jurisdictions in which the Company operates for years prior to 2003 in the U.S. and 2002
  in the U.K.
The Companys policy is to recognize any interest accrued related to unrecognized tax benefits as a component of interest expense and penalties in operating expenses. The Company did not
  have any accrued liabilities relating to interest and penalties as of September 30, 2007 or December 31, 2006.

8. Segments
The Companys business activities are organized and managed in two operating segments: financial guarantee insurance and financial guarantee reinsurance. These segments are managed
  separately because they provide different products or services to different customers, are subject to different regulation, and require different strategies. Products comprising the financial guarantee
  insurance segment primarily include financial guarantee insurance of public finance and structured finance debt securities and credit default swaps. Products comprising the reinsurance segment
  primarily include reinsurance of financial guarantee insurance products issued by financial guarantee insurance companies.
Set forth in the table below is certain financial information with respect to the Companys operating segments for each of the three-month and nine-month periods ended September 30, 2007 and
  2006. The accounting policies of the segments are the same as those described in the summary of significant accounting policies included in the notes to the Companys audited historical financial
  statements as of December 31, 2006 and 2005 and for the years ended December 31, 2006, 2005 and 2004 included in our Annual Report on Form 10-K. The Company evaluates the performance of
  each operating segment based on underwriting profit or loss before income taxes, nonrecurring items (e.g., items of an unusual or infrequent nature), and inter-segment transactions. Certain costs and
  operating expenses are allocated to each of the segments based on: (i) a review of the nature of such costs, and (ii) time studies analyzing the amount of employee compensation costs incurred by
  each segment.

    178,517Set forth below is a discussion of certain case basis reserves established by the Company. The Company has been indemnified with respect to loss development relating to the insurance
  transactions described under (a) and (b) below by subsidiaries of XL Capital in connection with SCAs IPO. As a result of such indemnifications, all adverse loss development on such insurance
  transactions subsequent to the effective date of the IPO, which is in excess of the Companys carried reserves for such transactions at the date of the IPO, was assumed by the aforementioned
  affiliates of XL Capital. Such protection does not relieve the Company of its obligations under the aforementioned insurance transactions. Accordingly, the Company is still liable under the insurance
  transactions in the event that the affiliates of XL Capital do not meet their obligations under the indemnifications. For further information with respect to the indemnifications see Note 6.
(a)
    
    
    
    As of September 30, 2007, the Company carried a gross case basis reserve for losses and loss adjustment expenses of approximately $74.0 million ($8.7 million after reinsurance to XLI and
      XL RE AM) relating to an insured project financing. There was no change in the reserve from December 31, 2006. The total remaining par insured by the Company in connection with this
      transaction is $215.8 million, net of applicable carried gross case reserves, as of September 30, 2007. After the reinsurance indemnity provided by subsidiaries of XL Capital and the case basis
      reserve discussed above the Company has no remaining net exposure to this transaction. The estimate of loss is based on assumptions and estimates extending over many years into the future.
      There is currently no payment default with respect to this transaction. Management continues to19

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
monitor the exposure and will revise its loss estimate if necessary, as new information becomes available.(b)
    
    
    
    As of December 31, 2006, the Company carried a liability of $5.0 million relating to a dispute in regard to certain exposures associated with notes which were insured by the Company and
      collateralized by loans to medical providers. Because the Companys liability in regard to this dispute was fully indemnified by XLA pursuant to the indemnification discussed above and in
      Note 6, the Company also carried a recoverable from XLA for $5.0 million as of December 31, 2006. During the three months ended March 31, 2007, the Company reduced the liability and
      corresponding recoverable from XLA by $1.1 million to reflect an agreement in principle among the parties to settle the dispute in exchange for a payment by the Company of $3.9 million.
      The settlement payment was made in May 2007 reducing the reserve and related recoverable to zero.(c)
    
    
    
    As of December 31, 2006, the Company carried a case basis reserve for losses and loss adjustment expenses of $3.3 million (none of which was reinsured) representing the present value of the
      loss expected to be incurred in the future with respect to an insured residential mortgage securitization. During the three months ended March 31, 2007, the insured obligation was retired as a
      result of the exercise of a clean-up call by the sponsor of the securitization thereby eliminating the Companys exposure without loss. Accordingly, the Company recorded a reduction in its
      provision for losses and loss adjustment expenses for the three months ended March 31, 2007 of $3.3 million resulting from the elimination of the aforementioned reserve.10. Earnings per Common Share
Basic earnings per common share is computed by dividing net (loss) or income by the weighted average number of common shares outstanding during the period excluding the dilutive effect of
  stock option and restricted stock awards outstanding. Diluted earnings per common share is computed by dividing net income by the weighted average number of common shares outstanding
  including the dilutive effect of stock option and restricted stock awards outstanding. However, the calculation of diluted loss per share excludes the dilutive effect of stock option and restricted stock
  awards outstanding because it would otherwise have an anti-dilutive effect on net loss per share (i.e. reduce the loss per share).
The following table sets forth the computation of basic and diluted earnings per share:

    The computation of diluted earnings per share for the three and nine month periods ended September 30, 2007 does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect on earnings per
      share (i.e. reduce the loss per share). Such dilutive securities aggregated 97,042 and 177,691, for the three and nine months ended September 30, 2007, respectively, which share amounts were determined in accordance with the Treasury Stock
      Method. Accordingly, our reported diluted net loss per share for the three and nine month periods ended September 30, 2007 are based on the weighted average shares outstanding during such periods, respectively, which is the same as that used
      for Basic earnings per share reported in such periods because it does not include the effect of our outstanding restricted stock and stock option awards.20

11. Exposures under Guarantees
The Company provides financial guarantee insurance and reinsurance to support public and private borrowing arrangements. Financial guarantee insurance guarantees the timely payment of
  principal and interest on insured obligations to third party holders of such obligations in the event of default by an issuer. The Companys potential liability in the event of non-payment by the issuer
  of an insured or reinsured obligation represents the aggregate outstanding principal insured or reinsured under its policies and contracts and related interest payable at the date of default. In addition,
  the Company provides credit protection on specific assets referenced in its credit default swaps which consist of structured pools of corporate obligations (see Note 3). Under the terms of credit
  default swaps, the seller of credit protection makes a specified payment to the buyer of credit protection upon the occurrence of one or more specified credit events with respect to a reference asset.
  The Companys potential liability under credit default swaps represents the notional amount of such swaps that it guarantees.
As of September 30, 2007, the Companys net outstanding par exposure under its in-force financial guarantee insurance and reinsurance policies and contracts aggregated to $105.0 billion and net
  reserves for losses and loss adjustment expenses relating to such exposures was $81.0 million, consisting of case basis and unallocated reserves of $10.4 million and $70.6 million, respectively. In
  addition, as of September 30, 2007, the Companys notional exposure under credit default swaps aggregated to $49.2 billion and net reserves for losses and loss adjustment expenses relating to such
  exposures was $17.0 million, consisting of case basis and unallocated reserves of $0 and $17.0 million, respectively.
12. Stock-Based and Long-Term Compensation Plans
Prior to the IPO, certain employees of the Company participated under XL Capitals stock-based and long-term compensation plans and expense relating thereto was reflected in the Companys
  results of operations. Subsequent to the IPO, SCA adopted its own stock-based and long-term incentive plan and certain awards to employees of the Company under XL Capitals stock-based
  compensation and long-term incentive plans were converted to SCAs plans. Expense relating to awards to employees of the Company under XL Capital plans that were not so converted and remain
  outstanding continues to be recognized in the Companys financial statements.
Set forth below is certain information in regard to stock option and restricted stock awards made under SCAs stock-based and long-term incentive plan, as well as certain information in regard
  to awards to SCA employees that remain outstanding under XL Capitals stock-based compensation and long-term incentive plans.

The aggregate pre-tax intrinsic value that would have been received by the option holders had all option holders exercised their options on September 30, 2007 is $1.5 million. Intrinsic value
  represents the difference between the Companys stock price and the exercise price, multiplied by the number of in-the-money-options. Total unrecognized stock based compensation expense related
  to non-vested stock options was approximately $4.2 million as of September 30, 2007, related to 877,788 options, which is expected to be recognized over a weighted-average period of 2.6 years.

  $4.4 million, respectively, of compensation expense related to its restricted stock awards. Total unrecognized stock based compensation expense related to non-vested restricted stock was
  approximately $24.8 million at September 30, 2007, which is expected to be recognized over a weighted- average period of 3.6 years.
SCA Long-Term Compensation Plans
a. Deferred Cash Awards
Effective August 4, 2006, all outstanding and unvested awards to employees of the Company under XL Capital plans, known as deferred cash awards, were involuntarily converted to awards
  under SCAs plan. All the terms, conditions and values of the awards made under SCAs plan pursuant to such conversion were structured to mirror the terms of the awards made under XL Capitals
  plan. The awards vest as set forth in the applicable award agreements, and the requisite service period is equivalent to the vesting period. The awards contain certain restrictions, prior to vesting,
  relating to, among other things, forfeiture in the event of termination of employment and transferability.
During the three and nine months ended September 30, 2007, the Company recognized approximately $1.1 million and $4.0 million of compensation expense, respectively, related to deferred cash
  awards. Also, during the three and nine months ended September 30, 2007, the Company granted deferred cash awards of approximately $0 and $1.0 million, respectively. Total unrecognized
  compensation expense related to non-vested deferred cash awards was approximately $10.9 million as of September 30, 2007. The non-vested unrecognized compensation expense relating to the
  deferred cash awards are expected to be recognized over a weighted-average period of 1.75 years.
b. Long-Term Incentive Plan Awards
In connection with the IPO, XL Capital and the Company offered eligible employees of the Company the opportunity to exchange all of their outstanding unvested restricted Class A Ordinary
  Shares of XL Capital and options to purchase Class A Ordinary Shares of XL Capital, which were
22

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
awarded to such employees under XL Capital Plans prior to the IPO, for a long-term incentive plan award (the LTIP Award) from SCA to be granted under SCAs Plan (the Exchange Offer).
An LTIP Award is the right to receive a cash payment, or base amount, from SCA of no less than 75% of the target amount indicated in each offerees award letter. Such target amount will
  be adjusted higher or lower (but in no event lower than the base amount) based on the performance of SCA pursuant to the terms and conditions specified in the award. The awards vest as set forth
  in the applicable award agreements, and the requisite service period is equivalent to the vesting period. The awards contain certain restrictions, prior to vesting, relating to, among other things,
  forfeiture in the event of termination of employment and transferability.
The aggregate amount of LTIP Awards outstanding at September 30, 2007 was $16.2 million. There were no cancellations, forfeitures, or new issuances of such awards during the three and nine
  months ended September 30, 2007. During the three and nine months ended September 30, 2007, the Company recognized $2.7 million and $6.0 million of compensation expense relating to such
  awards, respectively. Total unrecognized compensation expense related to non-vested LTIP Awards based on managements best estimate of the ultimate payout or value of such awards was
  approximately $9.9 million as of September 30, 2007. The non-vested unrecognized compensation expense relating to LTIP Awards are expected to be recognized over a weighted-average period of
  1.25 years.
Refer to Note 6 for information regarding outstanding unvested restricted Class A Ordinary Shares of XL Capital and options to purchase Class A Ordinary Shares of XL Capital that were not
  exchanged under the Exchange Offer and remain outstanding under XL Capital plans.
13. Series A Perpetual Non-Cumulative Preference Shares
On April 5, 2007, SCA consummated the sale of $250 million Series A Perpetual Non-Cumulative Preference Shares (the SCA Series A Preference Shares) which were offered for sale pursuant
  to a private placement. Gross proceeds from the offering were $250.0 million, offering costs were $3.4 million, and net proceeds were $246.6 million. The SCA Series A Preference Shares are
  perpetual securities with no fixed maturity date and, if declared by the Board of SCA, will pay a fixed dividend, on a semi-annual basis during the first and third quarters of each fiscal year, at the
  annualized rate of 6.88% until September 30, 2017. After such date, the Series A Preference Shares, if declared by the Board of SCA, will pay dividends, on a quarterly basis, at a floating rate based
  on three-month LIBOR plus 2.715%. Dividends on the SCA Series A Preference Shares are non-cumulative. The SCA Series A Preference Shares have a liquidation preference of $1,000 per
  preference share.
In connection with the sale of the SCA Series A Preference Shares, the Company entered into a Replacement Capital Covenant (the Replacement Capital Covenant), whereby the Company
  agreed for the benefit of holders of one or more designated series of its long-term debt securities that the Company may issue in the future that (i) the Company will not redeem, exchange or
  purchase the SCA Series A Preference Shares and (ii) none of the Companys subsidiaries will purchase or exchange the SCA Series A Preference Shares, except, subject to certain limitations, to the
  extent that the applicable redemption, exchange or purchase price does not exceed a specified amount of cash proceeds from the sale of certain specified qualifying replacement capital securities
  raised during the period commencing on the 180th calendar day prior to the date of notice of the redemption or the date of purchase. The Company has made no decision as to whether, or when, it
  would issue debt securities that would have the benefit of that covenant. While such provisions are in effect, there could be circumstances where the Company would wish to redeem, exchange or
  purchase some or all of the SCA Series A Preference Shares but be restricted from doing so. The Replacement Capital Covenant may be terminated if (i) holders of at least a majority by principal
  amount of the then-effective series of covered debt consent or agree in writing to
23

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
terminate the Replacement Capital Covenant, (ii) the Company no longer has outstanding any indebtedness that qualifies as covered debt or (iii) the Company no longer has any outstanding SCA
  Series A Preference Shares. In addition, if not earlier terminated, the Replacement Capital Covenant will terminate on September 30, 2047; provided, however, that the September 30, 2047
  termination date may be extended at the Companys option.
On September 20, 2007, SCA filed a registration statement with the Securities and Exchange Commission on Form S-4 pursuant to which SCA intends to exchange new registered Non-
  Cumulative Perpetual Preferred Shares for the unregistered SCA Series A Preference Shares (the Exchange Offer). The Exchange Offer is intended to satisfy our obligations under the registration
  rights agreement executed in connection with the issuance of the SCA Series A Preference Shares.
14. Other Matters
On August 30, 2007, SCA filed a universal shelf registration statement on Form S-3 with the Securities and Exchange Commission, which became effective on such date and provides for the
  issuance of any or a combination of debt, equity and other forms of securities.
15. Subsequent Event
(a)
    
    
    
    The Company is exposed to risks associated with the deterioration in the credit markets. Recently, and continuing subsequent to September 30, 2007, credit spreads across most bond sectors have
      continued to widen reflecting broad concerns of potential credit erosion in U.S. residential mortgage loans, particularly to subprime borrowers, that are contained in the residential mortgage-
      backed securities (RMBS) and collateralized debt obligations of asset-backed securities (ABS CDOs) the Company insures or reinsures. Subprime residential mortgage loans originated in
      years subsequent to 2005 are performing significantly worse than similar loans made prior to 2005. While the Company has sought to underwrite RMBS and ABS CDOs with levels of
      subordination designed to protect it from loss in the event of poor performance on the underlying collateral, no assurance can be given that such levels of subordination will prove to be adequate
      to protect the Company from material losses in view of the significantly higher rates of delinquency, foreclosure and loss currently being observed among residential homeowners, especially
      subprime borrowers.Transactions within the Companys insured RMBS and CDO portfolios also may be downgraded, placed on watch or subject to other actions by the three rating agencies that have granted the
      Company its triple-A claims-paying ratings. Such ratings actions could require the Company to maintain a material amount of additional capital to support the exposures it has insured and
      reinsured. This could cause the Company to: (i) have to raise additional capital, if available, on terms and conditions that may be unfavorable, (ii) curtail the production of new business, or (iii)
      pay to reinsure or otherwise transfer certain of its risk exposure. The Company regards its triple-A ratings as fundamental to the execution of its business plan and the loss of one or more of its
      triple-A ratings could materially impair its ability to continue to execute that plan.
    On November 5, 2007, Fitch, Inc. (Fitch) and on November 8, 2007, Moodys Investors Service Inc. (Moodys) announced that they would be reevaluating the adequacy of the capital position
      of companies comprising the financial guarantee insurance industry in view of recent developments adversely affecting the performance of subprime residential mortgage loans. Fitch observed that
      there is a moderate probability that the Company may experience pressure in its capital cushion under Fitchs updated stress analysis. Fitch noted that at the conclusion of its analysis, should a
      financial guarantors capital ratio fall below Fitchs AAA capital guidelines, Fitch would expect to place any24

SECURITY CAPITAL ASSURANCE LTDNOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (continued)
such insurers financial strength rating on rating watch negative with a downgrade to follow if a risk mitigation strategy or capital raise is not completed within approximately one month.
      Moodys noted there is a moderate risk of the Company falling below Moodys Aaa capital adequacy benchmark under a stress scenario. Moodys stated that by the end of November 2007, it
      expects to complete its analysis on the financial guarantors capital ratios which, for some companies, could result in a rating affirmation, a change in outlook, a review for downgrade, or a
      downgrade.
    On November 12, 2007, Fitch announced the downgrade of 352 structured finance CDO transactions, of which two transactions are insured by the Company. Such transactions represent $792
      million in net par insured or approximately 0.5% of the Companys total net insured par outstanding. One of the Companys insured transactions of approximately $371 million net par, originally
      rated AAA by Fitch on June 1, 2007, was downgraded to CCC. The other transaction of approximately $421 million net par, originally rated AAA by Fitch on March 29, 2007, was downgraded
      to BBB. The Companys portfolio contains only one other SF CDO rated by Fitch. This transaction of approximately $573 million net par, originally rated AAA by Fitch on June 27, 2006,
      remains under review.
    Downgrades of credits that we insure, such as those made by Fitch on November 12, 2007, will result in higher capital charges to the Company under the relevant rating agency model or models.
      If the additional amount of capital required to support such exposures is significant, the Company could be required to raise additional capital, if available, on terms and conditions that may not
      be favorable to the Company, curtail current business writings, or pay to transfer a portion of its in-force business to generate capital for ratings purposes with the goal of maintaining its triple-A
      ratings. Among other things, such events or goals may not be obtainable, and such events or actions could adversely affect the results of operations and financial condition of the Company going
      forward.(b)
    
    
    
    On November 6, 2007 our Board of Directors declared a quarterly dividend of $.02 per common share payable on December 31, 2007 to shareholders of record on December 14, 2007. Any future
      dividends will be subject to the discretion and approval of the Board of Directors.25

ITEM 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis of our financial condition and results of operations contains forward-looking statements that involve risks and uncertainties. Our actual results could differ
  materially from those anticipated in these forward-looking statements as a result of various factors, including those discussed below. See also, Cautionary Note Regarding Forward-Looking Statements
  below for a list of factors that could cause actual results to differ materially from those contained in any forward-looking statement.
Overview
General
We are a Bermuda-domiciled holding company whose operating subsidiaries provide credit enhancement and protection products to the public finance and structured finance markets throughout
  the United States and internationally.
We provide credit enhancement and protection through the issuance of financial guarantee insurance policies and credit default swaps, as well as the reinsurance of financial guarantee insurance
  and credit default products written by other insurers. Financial guarantee insurance provides an unconditional and irrevocable guarantee to the holder of a debt obligation of full and timely payment
  of principal and interest. In the event of a default under the obligation, the insurer has recourse against the issuer or any related collateral (which is more common in the case of insured asset-backed
  obligations or other non-municipal debt) for amounts paid under the terms of the policy. Credit default swaps are derivative contracts that offer credit protection relating to a particular security or
  pools of specified securities. Under the terms of a credit default swap, the seller of credit protection makes a specified payment to the buyer of credit protection upon the occurrence of one or more
  specified credit events with respect to a referenced security. Our financial guarantee reinsurance provides a means by which financial guarantee insurance companies can manage and mitigate risks in
  their in-force business and/or increase their capacity to write such business.
Key Factors Affecting Profitability
Impact of Economic Cycles
The financial guarantee business is significantly affected by economic cycles. For example, a robust economy featuring a good or improving credit environment is beneficial to the in-force
  portfolios of financial guarantee insurers and reinsurers. Historically, however, when such conditions have existed for an extended period, credit spreads tend to narrow and pricing and demand for
  financial guarantee insurance and reinsurance tend to decline. A weakening economic and credit environment, in contrast, is typically marked by widening credit spreads and increasing pricing for
  financial guarantee products. However, a prolonged period of weak or declining economic activity could stress in-force financial guarantee insured portfolios and result in claims or could adversely
  impact capital adequacy due to deterioration in the credit quality of in-force insured portfolios.
Recently, credit spreads across most bond sectors have widened reflecting broad concerns of potential credit erosion which have been caused by the widely published concerns over the U.S.
  residential mortgage and corporate credit sectors. This present trend has affected, or could affect, many companies such as ours which have exposure to the securities which have been issued over the
  years to finance the housing industry such as residential mortgage-backed securities (RMBS) and collateralized debt obligations of asset-backed securities (ABS CDOs). Specifically, in the current
  environment, transactions within our insured RMBS and CDO portfolios may be downgraded, placed on watch or subject to other actions by the three rating agencies that have granted our operating
  subsidiaries their triple-A claims-paying ratings (Moodys Investors Service, Inc., (Moodys), Standard & Poors, a division of the McGraw-Hill Companies, Inc., (S&P), and Fitch, Inc. (Fitch)). Such
  ratings actions could in turn require us to maintain a material amount of additional capital to support the exposures we have guaranteed. Among other things, this could cause us to: (i) have to raise
  additional capital, if available, on terms, and under conditions, that may be unfavorable which among other things could increase our
26

cost of capital, (ii) curtail the production of new business, or (iii) pay to reinsure or otherwise transfer certain of our risk exposure.
See Exposure to Residential Mortgage Market below for additional information in regard to our exposure to residential mortgages, Critical Accounting Policies and EstimatesValuation of
  Credit Default Swaps for information in regard to how our GAAP earnings are affected by the change in the fair value of our credit derivatives and Item 1A Risk FactorsRisks Associated with
  Recent Adverse Developments in the Credit Markets.
Components of Our Revenues
We derive our revenues principally from: (i) premiums from our insurance and reinsurance businesses, (ii) net investment income and net realized gains and losses from our investment portfolio
  supporting these businesses and (iii) realized and unrealized gains and losses on our credit derivatives.
Our premiums are a function of the amount of par or notional amount of debt obligations that we guarantee, market prices and the type of debt obligation guaranteed. We receive premiums
  either on an upfront basis when the policy is issued or the contract is executed, or on an installment basis over the life of the applicable transaction.
Premiums are accounted for as written when due; therefore when we enter into policies that provide for upfront premium, all of the premium on the policy is accounted for as written generally
  when the policy commences. The portion of the upfront premium that has been written but has not yet been earned is carried on our balance sheet as deferred premium revenue. When we enter into
  policies that provide for installment premium, only that installment of the premium that is then due (generally the current monthly, quarterly or semiannual installment) is accounted for as written.
  Future premium installments during the remainder of the life of the installment-based policy are not reflected on our financial statements. Therefore, the amount of total premiums written that we
  report for any period will be affected by the mix of policies that we wrote in that period on an upfront and, in that period and prior periods, on an installment basis. Generally, a financial
  guarantee insurance company with a growing in-force book of business should recognize an increasing amount of net earned premium from policies written in prior reporting periods, whether
  premiums are received on an upfront or installment basis. Future installments of premium on business written in a period are reported by financial guarantors as a component of adjusted gross
  premiums, a non-GAAP financial measure, which is discussed in more detail below. The amount of installment premiums actually realized by us in the future (and that would be otherwise reflected
  in revenue) could be reduced due to factors such as early termination of insurance contracts or accelerated prepayments of underlying obligations.
Our investment income is a function of the amount of our invested assets and the yield that we earn on those assets. The investment yield will be a function of market interest rates at the time
  of investment, as well as the type, credit quality and duration of our invested assets. In addition, we could realize gains or losses on the sale of securities in our investment portfolio or recognize an
  other-than-temporary impairment as a result of changing market conditions, including changes in market interest rates, and changes in the credit quality of our invested assets.
Unrealized gains and losses on credit default swaps and insurance policies that we account for as derivative contracts are a function of changes in the estimated fair value of those contracts.
  These unrealized gains and losses fluctuate primarily based on changes in credit spreads, the credit quality of the referenced securities, rates of return and various other factors. See Critical
  Accounting Policies and EstimatesValuation of Credit Default Swaps and Note 3 to the Unaudited Interim Consolidated Financial Statements for additional information.
Components of Our Expenses
Our expenses primarily consist of losses and loss adjustment expenses, acquisition costs, and operating expenses. Acquisition costs are related to the production of new financial guarantee
  insurance business and commissions paid on reinsurance assumed, net of commission revenues earned on ceded business. These costs are generally deferred and recognized over the period in which
  the related premiums are earned. Operating expenses consist primarily of costs relating to compensation of our employees, information technology, office premises, and professional fees.
27

Other Measures Used by Management to Evaluate Operating Performance
The following are certain financial measures management considers important in evaluating the Companys operating performance:
We evaluate our periodic sales performance by reviewing a non-GAAP measure known as adjusted gross premiums. Adjusted gross premiums for any period equals the sum of: (i) upfront
  premiums written in such period, (ii) current installment premiums on business written in such period and (iii) expected future installment premiums on contracts written during such period that
  remain in force and for which there is a binding obligation on the part of the insured to pay the future installment premiums, discounted at 7%, which we refer to as the present value of future
  installment premiums, or PVFIP, on business written during such period. The 7% discount rate was established when our subsidiaries first started reporting adjusted gross premiums based upon a
  view at the time that 7% was the appropriate discount for these future premiums and that rate has not been changed to date in order to preserve comparability among periods. This measure adjusts
  for the fact, as described above, that upfront premiums are recorded in full as total premiums written at inception of the contract but future installment premiums are not. PVFIP is not reflected on
  our consolidated balance sheet. PVFIP can be negatively affected by prepayments and refundings, early terminations, credit losses or other factors impacting our in-force book of business.
The following is a reconciliation of total premiums written to adjusted gross premiums. Total premiums written is the most directly comparable GAAP financial measure.

    358.9We also review non-GAAP measures known as operating income and core income. While operating income and core income are not substitutes for net income (loss) available to common
  shareholders computed in accordance with GAAP, they are useful measures of performance used by management, equity analysts and investors. Operating income measures net income available to
  common shareholders, as determined in accordance with GAAP, excluding net realized gains (losses) on investments, net unrealized gains (losses) on credit derivatives, and certain other items. In
  addition, in determining operating income, we have made an adjustment to the amount of dividends on our perpetual non-cumulative preference shares reported in accordance with GAAP during the
  period to reflect the amount of such dividends that would be attributable to the period as if such dividends were accrued ratably over the period. Core income represents operating income excluding
  the impact of refundings and other accelerations. The definitions of operating income and core income used by the Company may differ from definitions of operating earnings and core earnings used
  by other financial guarantors. See Offering of Series A Perpetual Non-Cumulative Preference Shares.
We also view our book value per share attributable to common shareholders as an additional measure of our performance. This metric is calculated by dividing common shareholders equity by
  the number of outstanding common shares (excluding outstanding restricted sharessee Note 12 to the Unaudited Interim Consolidated Financial Statements) at any period end. Book value per share
  attributable to common shareholders is affected primarily by our net income available to common shareholders and also by any changes in net unrealized gains and losses on our invested assets. Book
  value per share attributable to common shareholders was $21.00 at September 30, 2007, as compared to $21.31 at December 31, 2006. The decrease in book value was attributable to the net loss
  available to common shareholders, offset in part by a decrease in net unrealized losses on our invested assets.

The activities of our surveillance department are integral to the identification of specific credits that have experienced deterioration in credit quality and to the assessment of whether losses on
  such credits are probable, as well as any estimation of the amount of loss expected to be incurred with respect to such credits. Closely monitored credits are divided into four categories: (i) Special
  Monitoring Listinvestment grade credits where a covenant or trigger may be breached or is close to being breached and warrants closer monitoring; (ii) Yellow Flag Listcredits that we determine to
  be non-investment grade but a loss or claim is unlikely; (iii) Red Flag Listcredits where we do not expect an ultimate loss but a claim is possible but not probable; and (iv) Loss Listcredits where we
  have either paid a loss or expect to suffer a loss and have recorded a case reserve. Out of over 2,600 credits in our in-force portfolio, 22 credits are in one of the four above categories. Credits that
  are not closely monitored credits are considered to be fundamentally sound normal risks at the present time. Credits may be placed on or removed from such lists at anytime as circumstances and
  credit conditions change.
The following table presents our consolidated in-force financial guarantee net par outstanding at September 30, 2007 and December 31, 2006 by category of closely monitored credit:

Exposure to Residential Mortgage Market
The Company is exposed to residential mortgages directly, through our guarantees of residential mortgage-backed securities (RMBS) and indirectly, through our guarantees of CDOs of asset-
  backed securities. As of September 30, 2007, our total net exposure to residential mortgage-backed securities and CDOs of asset-backed securities aggregated approximately $8.9 billion and $16.1
  billion, respectively, representing approximately 5.8% and 10.4%, respectively, of our total in-force guaranteed net par outstanding at such date. Of our total direct guaranteed Subprime mortgage net
  par exposure at September 30, 2007 of $1.9 billion, 38% was rated AAA, 14% was rated AA+, 41% was rated AA, and 7% was rated A based on S&P ratings. All of our indirect Subprime
  net exposure arises from CDOs in which our guarantees attach higher than the minimum amount of subordination required under rating agency criteria in effect at the time of issue for a rating of
  AAA, based on S&P ratings. As of September 30, 2007, our indirect Subprime net exposure was approximately $3.0 billion based on the RMBS holdings within the ABS CDO collateral pools. In
  addition, the collateral pools of most of our ABS CDO transactions contain securities issued by other ABS CDOs. The indirect net exposure to other ABS CDOs was approximately $2.8 billion as of
  September 30, 2007, and a significant portion of the underlying collateral supporting these transactions consists of Subprime RMBS.
Set forth below is certain additional information in regard to our exposure to RMBS and CDOs:

Organization Background, Initial Public Offering, and Ownership by XL Capital
We were formed as an indirect wholly owned Bermuda based subsidiary of XL Capital on March 17, 2006. On July 1, 2006, XL Capital contributed all its ownership interests in its financial
  guarantee insurance and financial guarantee reinsurance operating businesses to us. The aforementioned operating businesses consisted of: (i) XL Capital Assurance Inc. (XLCA) and its wholly-
  owned subsidiary, XL Capital Assurance (U.K.) Limited (XLCA-UK) and (ii) XL Financial Assurance Ltd. (XLFA). XLCA was an indirect wholly owned subsidiary of XL Capital and all of
  XLFA was owned by XL Capital except for a preferred stock interest which is owned by Financial Security Assurance Holdings Ltd. (FSAH), an entity which is otherwise not related to XL
  Capital or us. On August 4, 2006, we completed the sale of 18,009,119 of our common shares through an initial public offering (the IPO) at $20.50 per share. We received net proceeds from the
  offering of $341.3 million. In addition, XL Capital sold 5,430,774 of our common shares (including 992,165 pursuant to the exercise of an over-allotment option granted to underwriters) from its
  holdings directly to the public in a secondary offering concurrent with our IPO. We did not receive any of the proceeds from the aforementioned sale by XL Capital. Immediately after the IPO and
  the secondary offering, XL Capital owned 40,696,471 of our common shares which represented approximately a 63 percent economic interest in SCA, adjusted for restricted share awards to our
  employees and management made at the effective date of the IPO. In June 2007, XL Capital completed the sale of an additional 10,627,422 common shares of SCA from its holdings (including
  947,400 common shares pursuant to the exercise of an over-allotment option granted to underwriters). We did not receive any of the proceeds from this sale. Immediately after such sale XL Capital
  owned 30,069,049 of our common shares which represented approximately a 46 percent voting and economic interest in SCA, adjusted for restricted share awards to our employees and management
  outstanding as of such date. Prior to XL Capitals sale of SCA common shares in June 2007 its voting interest in SCA was subject to limitations contained in our bye-laws.
Offering of Series A Perpetual Non-Cumulative Preference Shares
On April 5, 2007, we consummated the sale of $250 million of our Series A Perpetual Non-Cumulative Preference Shares (the SCA Series A Preference Shares) which were offered for sale
  pursuant to a private placement. Gross proceeds from the offering were $250.0 million, offering costs were $3.4 million, and net proceeds were $246.6 million. The SCA Series A Preference Shares
  are perpetual
33

securities with no fixed maturity date and, if declared by the Board of SCA, will pay a fixed dividend, on a semi-annual basis during the first and third quarters of each fiscal year, at the annualized
  rate of 6.88% until September 30, 2017. After such date, the Series A Preference Shares, if declared by the Board of SCA, will pay dividends, on a quarterly basis, at a floating rate based on three-
  month LIBOR plus 2.715%. Dividends on the SCA Series A Preference Shares are non-cumulative. The SCA Series A Preference Shares have a liquidation preference of $1,000 per preference share.

Segments
Our businesses are organized and managed in two operating segments: financial guarantee insurance and financial guarantee reinsurance. Our financial guarantee insurance segment offers
  financial guarantee insurance policies and credit default swaps. Our financial guarantee reinsurance segment reinsures financial guarantee policies and credit default swaps issued by other monoline
  financial guarantee insurance companies. We evaluate the performance of each operating segment based upon underwriting profit or loss before income taxes, nonrecurring items (for example, items
  of an unusual or infrequent nature) and inter-segment transactions. Certain costs and operating expenses are allocated to each of the segments based upon: (i) a review of the nature of such costs and
  (ii) time studies analyzing the amount of employee compensation costs incurred by each segment. Except for the foregoing allocations, the accounting policies of the segments are the same as those
  described in the summary of significant accounting policies in our consolidated financial statements presented in our Annual Report on Form 10-K.
Executive Overview
See certain information with respect to members of our Board of Directors, Executive Officers and Key Employees in our Annual Report on Form 10-K for the fiscal year ended December 31,
  2006, which was filed with the Securities and Exchange Commission on March 15, 2007.
Critical Accounting Policies and Estimates
The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with GAAP. The
  preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of
  the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. Actual results could differ from those estimates, and those differences may be
  material.
Critical accounting policies and estimates are defined as those that require management to make significant judgments, as well as those where results therefrom may be materially different under
  different assumptions and conditions. We have identified the accounting for losses and loss adjustment expenses, the valuation of credit default swaps and investments, premium revenue recognition,
  deferred acquisition costs, and deferred income taxes, as critical accounting policies.
An understanding of our accounting policies for these items is of critical importance to understanding our consolidated financial statements. See information with respect to our critical accounting
  policies and estimates in our Annual Report on Form 10-K for the fiscal year ended December 31, 2006, which was filed with the Securities and Exchange Commission on March 15, 2007. Also, in
  light of the significance of the change in the fair value of our credit default swaps during the three and nine month periods ended September 30, 2007, see below for an expanded discussion of our
  accounting policy in regard to the valuation of credit default swaps. This information should be read in conjunction with the notes to our unaudited interim consolidated financial statements.
Valuation of Credit Default Swaps
We issue and reinsure credit default swap contracts. Under the terms of a credit default swap contract we are generally required to make payments to our counterparty in the event of specific
  credit events relating to assets referenced in the contracts after exhaustion of various first-loss protection levels. These credit events are contract-specific, but generally cover bankruptcy and failure to
  pay. These credit
34

derivatives are not subject to collateral or margin requirements. Accordingly, the credit default swap contracts function like the guarantees of debt obligations that we provide in the form of
  insurance.
Assets referenced in our in-force credit default swap contracts consist of structured pools of corporate obligations. Such pools were awarded investment-grade ratings at the deals inception. At
  September 30, 2007, the notional amount outstanding of our in-force credit default swap contracts was $52.4 billion ($49.2 billion net of reinsurance) and the weighted average term of such contracts
  was 8.3 years. In addition, based on such notional amount, as of September 30, 2007 approximately 95.6% of the referenced assets underlying such in-force contracts were rated (based on S&P ratings)
  AAA, with the remaining 4.4% rated at or above investment-grade.
Our policy is to hold our credit default swap contracts to maturity and not to trade such contracts to realize gains or losses from periodic market fluctuations. However, in certain circumstances,
  we may choose to terminate a credit derivative prior to maturity for risk management or other purposes (for example, upon a deterioration in underlying credit quality). With the exception of two
  transactions which occurred in 2004 and 2003, respectively, there have been no such terminations since the Companys inception.
As derivative financial instruments, credit default swap contracts are required to be reported at fair value in accordance with GAAP, with changes in fair value during the period included in our
  earnings. The principal drivers of the fair value of our credit default swap contracts include: (i) general market credit spreads for the type(s) of assets referenced in our credit default swap contracts,
  (ii) the specific quality and performance of the actual assets referenced in the contracts, (iii) the amount of subordination in the transaction before liability attaches, (iv) the quality of the asset
  manager of the transaction, if applicable, (v) other customized structural features of such contracts (e.g. terms, conditions, covenants), (vi) the rating agency capital charge for the transaction, and (vii)
  supply and demand factors, including the volume of new issuance and financial guarantee market penetration, as well as the level of competition in the marketplace.
The fair value of our in-force portfolio of credit default swap contracts represents our estimate of the premium that would be required by a market participant to assume the risks in our credit
  derivative portfolio as of the measurement date. Fair value is defined as the price at which an asset or a liability could be bought or transferred in a current transaction between willing parties. Fair
  value is determined based on quoted market prices, if available. If quoted market prices are not available, fair value is estimated based on the use of valuation techniques involving management
  judgment. There are no observable readily available quoted market prices for most of our in-force guarantees under our credit default swap contracts since these contracts are generally not traded by
  market participants. Accordingly, our estimate of the fair value of our in-force credit default swap contracts is based on the use of valuation techniques involving management judgment, which
  considers a number of factors, including: (i) credit price indices, published by non-affiliated financial institutions, for the type(s) of assets referenced in our credit default swap contracts (both in terms
  of type of assets and their credit rating), (ii) estimates of rates of return which would be required by a counterparty to assume the risks in the Companys contracts in the current market environment,
  (iii) the quality of the specific assets referenced in our credit default swap contracts at the measurement date, (iv) the market perception of risk associated with such asset classes, (v) the amount of
  subordination in our transactions before our liability attaches relative to that required for similarly rated transactions in the current environment, (vi) the remaining average life of the transaction, (vii)
  prices of guarantees we have executed in proximity to the measurement date in our retail market. Because it is our policy to consider all available relevant evidence in forming our best estimate of
  the fair value of our credit default swaps, as new information becomes available we may consider new or different factors than those listed above and change our estimates in the future.
The weight ascribed by us to the aforementioned factors in forming our best estimate of the fair value of our credit default swap contracts may vary under changing circumstances. In periods
  prior to September 30, 2007, we principally considered price indices published by non-affiliated financial institutions in forming our best estimate of the fair value of our credit default swap contracts.
  The fair value of the guarantee was determined by multiplying the percentage change in the applicable credit price index or indices applicable to the assets referenced in the credit default swap by
  the present value of the
35

remaining expected future premiums to be received under the contract. We concluded that results from this calculation represented a reasonable estimate of the fair value of our credit default swap
  contracts at that time.
In forming our best estimate of the fair value our credit default swap contracts as of September 30, 2007, however, we concluded that limited reliance could be placed on price indices because
  events and conditions in the credit markets associated with subprime mortgage collateral and corporate loans resulted in limited transaction activity in many financial instruments during the period
  (including collateralized debt obligations (CDOs) of high grade asset-backed securities, collateralized loan obligations, residential mortgage-backed securities, and CDOs of CDOs), causing financial
  institutions which publish the indices that we historically relied upon to estimate the fair value of our credit derivatives either to refrain from updating such indices or base changes in the indices
  partly on judgments in regard to estimated price levels and not actual executed trades. In addition, evidence suggested that the limited price information available in the marketplace in regard to such
  instruments was influenced by trades resulting from margin calls and liquidity issues that are not part of the risks associated with our business model or credit default swap contracts. Accordingly, our
  estimate of the fair value of our credit default swap contracts as of September 30, 2007 ascribed significant weight to our judgments regarding rates of return that would be required by a counterparty
  to assume the risks in our contracts in the current market environment. Our judgment in regard to rates of return considered all the factors discussed above. Our estimate of fair value for the
  aforementioned financial instruments as of September 30, 2007 was calculated by adjusting the present value of the expected remaining future net cash flows under such contracts (which are
  comprised of the remaining expected future premiums to be received under the contract, less estimated maintenance expenses and a provision for expected losses that will manifest in the future) to
  reflect our best estimate of the rates of return that would be required by a counterparty to assume the risks on such contracts.
Present values of the cash flows referred to above were determined using a discount rate of 6.0%, which reflects the weighted average life of our in-force credit default swaps and the corporate
  credit rating of the issuer/reinsurer of such contracts, XLCA and XLFA, respectively, at September 30, 2007.
Because we view the credit default contract we issue and reinsure as an extension of our financial guarantee business, we believe that the most meaningful presentation of these derivatives is to
  reflect: (i) fees that we receive from the issuance of such contracts in the line item captions in the statement of operations entitled gross premiums written, reinsurance premium assumed, net
  premiums written and net premiums earned, as appropriate, (ii) losses from actual and expected payments to counterparties under such contracts in the line item caption in the statement of
  operations entitled net losses and loss adjustment expenses and (iii) changes in the fair value of such instruments which are attributable to market factors, as discussed below, in the line item
  caption in the statement of operations entitled net unrealized gains (losses) on credit derivatives.
At September 30, 2007, the fair value of the Companys credit derivatives was $180.8 million. Because this amount reflects managements best estimate of the premium we would have to pay a
  counterparty to transfer the risks in our portfolio of credit derivatives in one or more hypothetical transactions in excess of that which we charged for such risk, it is reflected in our balance sheet as
  a liability. A parallel shift in the rates of return used by management to value the portfolio at September 30, 2007 by 1.0% would cause a change in the fair value of our credit derivative portfolio by
  approximately $11.9 million. In addition, a parallel shift in the discount rate of 1.0% used to estimate the present value of cash flows under our credit default swap contracts would cause a change in
  the fair value of our credit derivative portfolio by approximately $5.5 million.

Discussion of Consolidated and Segment Results of Operations for the Three Months Ended September 30, 2007 Compared to the Three Months Ended September 30, 2006
Summary Discussion of Consolidated Results of Operations
Comparison of three months ended September 30, 2007 to three months ended September 30, 2006. Net loss available to common shareholders for the three months ended September 30, 2007 was
  $89.9 million, a decrease of $118.3 million from net income of $28.4 million reported during the same period in 2006. The net loss for the three months ended September 30, 2007 included $8.0
  thousand of net realized gains on investments, as compared to net realized losses of approximately $0.2 million recorded during the same period in 2006. In addition, also included in net loss available
  to common shareholders for the three months ended September 30, 2007 was approximately $143.0 million of net unrealized losses on credit derivatives, as compared to net unrealized losses on credit
  derivatives of $3.2 million recorded in the comparable period in 2006.
The decrease in net income available to common shareholders of $118.3 million for the three months ended September 30, 2007, as compared to the same period in 2006, was primarily driven by:
  (i) higher net unrealized losses on credit derivatives of $139.8 million, resulting primarily from widening credit spreads on assets referenced in our in-force credit derivative portfolio, particularly
  subprime mortgage loan assets, which exist in our guarantees of senior triple-A high-grade structured finance CDOs, (ii) the semi-annual dividend on our Series A perpetual non-cumulative
  preference shares of $8.4 million, (iii) higher operating expenses of $4.7 million resulting primarily from increased compensation and continued investment in our infrastructure, as well as costs
  associated with an increase in the volume of our credit default swap business (which are not deferred under GAAP), and (iv) higher net losses and loss adjustment expenses of $2.4 million primarily
  due to an increase in unallocated reserves as a result of growth in the portfolio, as well as an increase in loss adjustment expenses relating to a guaranteed international consumer asset-backed
  securities transaction, offset in part by (v) higher earned premiums of $12.7 million driven by the CDO, public finance and consumer ABS lines of business, (vi) a decrease in income taxes of $12.6
  million driven by an income tax benefit relating to the net loss reported for the quarter, (vii) an increase in net investment income of $9.8 million reflecting a significant period over period increase in
  average invested assets and higher yields on new money investments, and (viii) a decrease in acquisition costs of $1.4 million primarily driven by an increase in ceding commission revenue earned in
  the current quarter, as compared to the same period in 2006.
Set forth below is additional information with respect to earned premiums and new business production.
Net premiums earned for the three months ended September 30, 2007 of $58.2 million included $5.0 million of earnings from refundings of insured obligations and other accelerations (or $5.0
  million, net of accelerated amortization of deferred acquisition costs related to the earnings from such refundings and other accelerations). Net premiums earned for the three months ended
  September 30, 2006 of $45.5 million included $0.4 million of earnings from refundings of insured obligations and other accelerations (or $0.3 million, net of accelerated amortization of deferred
  acquisition costs related to the earnings from such refundings and other accelerations).
Our business production as measured by adjusted gross premiums (which includes upfront premiums written in the period, current installment premiums due on business written in the period and
  expected future installment premiums on business written during the period discounted at 7.0%) totaled $141.1 million for the three months ended September 30, 2007, an increase of $49.8 million, as
  compared to $91.3 million reported in the comparable period in 2006. The increase was primarily due to higher production in the following lines of business: Public Finance of $17.2 million,
  Commercial ABS of $16.8 million, Global Infrastructure of $14.7 million and CDOs of $11.4 million. These increases were offset in part by lower adjusted gross premium production in the following
  lines of business: Reinsurance of $3.5 million, Municipal Guaranteed Investment Contract program of $2.8 million, and Specialized Risk of $2.6 million.

Detailed Discussion of Consolidated and Segment Results of Operations by Financial Statement Line Item
Gross Premiums Written
All our gross premiums written are from our financial guarantee insurance segment. Gross premiums written during the period include: (i) premiums received upfront on policies or contracts
  written during the period, (ii) installment premiums due during the period on in-force policies or contracts that were written prior to the period, and (iii) installment premiums due during the period
  on policies and contracts written during the period. Gross premiums written during the period do not include installment premiums due in future periods. Accordingly, our premiums written during
  any period are a function of the type and volume of contracts we write (upfront versus installment), as well as prevailing market prices. Factors affecting market prices include credit spreads, interest
  rates, competition and new issuance. Generally, financial guarantee insurers are able to charge higher premiums when credit spreads widen. The following table presents, for the periods indicated, the
  amount of gross premiums written attributable to upfront and installment policies and contracts:

    65,081Gross premiums written were $88.1 million for the three months ended September 30, 2007, an increase of $23.0 million or 35.3%, as compared to $65.1 million recorded in the comparable
  period in 2006. The increase was primarily attributable to the $14.6 million favorable variance in international finance gross premiums written and the $12.3 million favorable variance in structured
  finance gross premiums written. The increase in international finance gross premiums written primarily reflects the growth of our Power and Utilities and Global Infrastructure businesses. The
  increase in structured finance reflects the growth of our in-force book of guarantees of consumer ABS and CDOs.
Reinsurance Premiums Assumed
All our reinsurance premiums assumed are from our financial guarantee reinsurance segment. The majority of our financial guarantee reinsurance business is assumed from affiliates of FSAH.

    20,489Reinsurance premiums assumed were $22.6 million for the three months ended September 30, 2007, an increase of $2.2 million or 10.7%, as compared to $20.5 million recorded in the comparable
  period in 2006. The increase was due to higher public finance assumed premiums of $0.9 million, higher structured finance assumed premiums of $0.9 million and higher international finance assumed
  premiums of $0.4 million. Public finance increased primarily due to a few upfront general obligation transactions assumed during the current quarter. Structured finance increased primarily due to
  increased structured single risk premiums during the current quarter. The amount of reinsurance ceded to us depends upon the type and amount of insurance written by primary companies, their
  capital needs and other factors. Such reinsurance is generally structured on a facultative basis.
Ceded Premiums
We manage our in-force business based on single-risk limits to avoid concentration in single names and to mitigate event risk. For transactions that exceed our single-risk limits, we cede the
  excess to XLI, XL Reinsurance America, Inc. (XL RE AM, an indirect wholly owned subsidiary of XL Capital), or third-party reinsurers. Through these cessions, we gain greater flexibility to
  manage large single risks and reduce concentration in specific bond sectors and geographic regions. Part of our long-term strategy is to reduce reinsurance to XLI and XL RE AM, and increase our
  third-party reinsurance relationships. To the extent that we cede a portion of our exposure to one or more reinsurance companies, we can reduce our concentration to particular issuers and help to
  control the diversification of our in-force business. In
41

addition, use of reinsurance can increase our capacity to write new business and strengthen our capital adequacy.
The following table presents, for the periods indicated, the amount of premiums ceded to XLI, XL RE AM and other third-party reinsurers:

  million, as compared to the prior year period. Ceded premiums written in the three months ended September 30, 2006 of $14.9 million reflect the return of $26.5 million of premiums previously ceded
  to XLI in accordance with a commutation effective on the date of our IPO. Ceded premiums written in the three months ended September 30, 2007 include $(17.3) million relating to the retrocession
  of $3.7 billion par/notional exposure to XLI effective July 1, 2007, which was undertaken for risk and capital management purposes.
Net Premiums Earned
Financial guarantee upfront premiums are earned in proportion to the expiration of the related risk and financial guarantee installment premiums are earned ratably over the installment period,
  generally one to three months. In addition, when an insured issue is retired early, is called by the issuer or is in substance paid in advance through a refunding accomplished by placing U.S.
  Government securities in escrow, the remaining deferred premium revenue is earned at that time. While reinsurance premiums assumed are earned based on reports from the reinsured companies, we
  believe that the underlying reinsured companies generally follow the revenue recognition policies and practices discussed above.

  The increase in earned premiums was primarily attributable to higher earned premiums in our financial guarantee insurance segment of $9.5 million and higher earned premiums in our financial
  guarantee reinsurance segment of approximately $3.2 million. Higher earned premium in our financial guarantee insurance segment was primarily attributable to growth in earned premiums from our
  CDO, public finance and consumer asset-backed businesses and an increase in refundings and other accelerations during the period of $2.1 million, offset in part by higher earned premiums ceded to
  XLI. Higher earned premium in our financial guarantee reinsurance segment was primarily attributable to an increase in refundings and other accelerations during the period of $2.6 million.
Net Investment Income
Net investment income was $31.6 million for the three months ended September 30, 2007, an increase of $9.8 million or 45.0% as compared to $21.8 million in the comparable period in 2006.
  The increase in
42

net investment income was due primarily to higher average invested assets, higher new money yields and a longer portfolio duration. The increase in our average invested assets period over period
  was primarily attributable to operating cash flows since the comparable period in 2006 and the net proceeds from the SCA Series A Preference Shares, which were issued in April 2007. Also
  contributing to the increase in average invested assets were the net proceeds from our IPO, cash capital contributions from XL Capital, and the transfer of certain business to us from affiliates of XL
  Capital in connection with our IPO, which was consummated on August 4, 2006.
The following tables present net investment income, average invested assets, the effective yield on our average invested assets, and the average duration of our invested assets as of and for the
  three months ended September 30, 2007 and 2006, respectively. See Investments for information regarding the credit quality of our debt securities.

Net realized gains on investments were $8.0 thousand for the three months ended September 30, 2007, as compared to net realized losses of approximately $0.2 million in the comparable period
  in 2006. The net losses realized during the three months ended September 30, 2006, were primarily attributable to portfolio dispositions relating to the management of duration, yield and credit risk.
Net Unrealized Losses on Credit Derivatives
The Companys derivative financial instruments principally include credit default swaps issued to its customers. Changes in the fair value of credit default swaps attributable to earnings from
  premiums received by us from the issuance of such contracts are recorded in net premiums earned in the consolidated statement of operations. In addition, changes in the fair value of credit default
  swaps attributable to losses from actual and expected payments to counterparties under such contracts are recorded in losses and loss adjustment expenses in the consolidated statement of operations,
  and the remaining components of the change in fair value of credit default swaps, which are attributable to changes credit spreads, credit quality, interest rates, rates of return, and various other
  factors are recorded in net unrealized losses on credit derivatives. See Critical Accounting Policies and EstimatesValuation of Credit Default Swaps or Note 3 to the Unaudited Interim
  Consolidated Financial Statements for additional information.
Net unrealized losses on credit derivatives were $143.0 million for the three months ended September 30, 2007, an increase of $139.8 million, as compared to unrealized losses of $3.2 million
  reported in the comparable period in 2006. The unrealized loss on our credit derivatives resulted from widening credit spreads across most sectors, particularly Senior AAA High-Grade Structured
  Finance CDOs, which accounted for $85.1 million of unrealized losses on approximately $15.3 billion of par exposure. In addition, our credit derivatives on CLOs and investment-grade corporate
  synthetic CDOs accounted for unrealized losses of $39.0 million and $10.7 million, respectively for the three months ended September 30, 2007, due to widening credit spreads in the specific sectors
  underlying these instruments. There was no
43

change in the credit rating of the referenced assets underlying our credit default swaps during the three month period ended September 30, 2007.
Net Losses and Loss Adjustment Expenses

    In connection with the cancellation from inception of certain business ceded by the Company to XLI in connection with our IPO, XLI assumed the Companys obligation for loss adjustment expenses relating to such business  see Note 6 to the
      unaudited interim consolidated financial statements herein.Net losses and loss adjustment expenses were $7.4 million for the three months ended September 30, 2007, an increase of $2.4 million, or 48.0%, as compared to $5.0 million recorded in the
  comparable period in 2006. The increase in net losses and loss adjustment expenses was primarily attributable to higher net losses and loss adjustment expenses in the insurance segment of $2.3
  million. Net losses and loss adjustment expenses in the financial guarantee reinsurance segment remained essentially the same year over year.
Higher net losses and loss adjustment expenses in the financial guarantee insurance segment during the three months ended September 30, 2007 were primarily due to an increase in unallocated
  reserves of $1.2 million due to growth in our in-force business and an increase in loss adjustment expenses of $1.1 million relating to a guaranteed international consumer asset-backed securities
  transaction, as compared to the same period in 2006.
In the financial guarantee reinsurance segment, period over period losses and loss adjustment expenses remained essentially the same, as unallocated reserves increased $0.1 million due to growth
  in our in-force business and case basis provisions for losses and loss adjustment expenses decreased $0.1 million.

    5,824Capitalized acquisition costs in the financial guarantee insurance segment consist of premium and excise taxes, rating agency fees and legal costs associated with the production of new business, as
  well as a portion of compensation, travel and entertainment and marketing costs. Such capitalized acquisition costs are reduced by ceding commission income on premiums ceded to reinsurers.
Net acquisition costs in the financial guarantee insurance segment decreased $1.9 million, or 46.0% in the three months ended September 30, 2007, as compared to the same period in 2006. The
  decrease was primarily due to an increase in ceded premiums earned and lower amortization of acquisition costs during the current quarter.
Acquisition costs in the financial guarantee reinsurance segment represent commissions paid to acquire assumed business. Amortization of acquisition costs in the financial guarantee reinsurance
  segment was $2.1 million during the three months ended September 30, 2007, an increase of $0.5 million, as compared to the same period in 2006. As acquisition costs are recognized as revenue is
  earned, the increase is consistent with the increase in net premiums earned in the financial guarantee reinsurance segment.
Operating Expenses
Operating expenses were $25.6 million for the three months ended September 30, 2007, an increase of $4.7 million or 22.5%, as compared to $20.9 million in the comparable period in 2006.
  Operating expenses for the three months ended September 30, 2007 are comprised of operating expenses of our financial guarantee insurance and reinsurance segments, as well as corporate operating
  expenses, which consist of costs associated with SCA being a stand-alone public company. Operating expenses of our financial guarantee insurance and reinsurance segments aggregated $21.8 million
  for the three months ended September 30, 2007, an increase of $3.7 million, as compared to $18.1 million in the same period in 2006. The increase in operating expenses of our financial guarantee
  insurance and reinsurance segments resulted primarily from: (i) increased compensation related, in part, to a net increase in the number of our employees, (ii) an increase in the volume of our credit
  default swap business (the costs of which cannot be deferred), and (iii) continued investment in our infrastructure. During the three months ended September 30, 2007 we reported corporate operating
  expenses of $3.8 million, an increase of $1.1 million, as compared to the $2.7 million in the same period of 2006. Corporate expenses for the three months ended September 30, 2006 include only two
  months of expenses as our IPO was effective August of 2006.
Income Tax (Benefit) Expense
For the three months ended September 30, 2007, we reported an income tax benefit of $9.9 million, a decrease of $12.6 million, as compared to income tax expense of $2.7 million reported in the
  comparable period in 2006. The income tax benefit reported in the current quarter resulted from the net loss reported during the period, which was primarily driven by the unrealized loss on credit
  derivatives recorded during the quarter. See Note 7 to the Unaudited Interim Consolidated Financial Statements.

Minority Interest  Dividends on Redeemable Preferred Shares
Dividends on redeemable preferred shares were $0.8 million for the three months ended September 30, 2007, a decrease of $0.3 million, as compared to $1.1 million recorded during the same
  period in 2006. The decrease was due to an extraordinary dividend of $15.0 million paid by XLFA on its preferred shares on March 30, 2007 and a corresponding reduction in the stated value of the
  remaining outstanding Series A Redeemable Preferred Shares. As a result of the reduction in stated value, dividends on the redeemable preferred shares are $0.8 million quarterly subsequent to
  March 31, 2007. See Liquidity and Capital Resources  XLFA Preferred Share Dividend Requirements.
Dividends on SCA Series A Preference Shares
Because dividends on our SCA Series A Preference Shares are non-cumulative and the declaration of such dividends are subject to the discretion of the Companys Board of Directors, under
  GAAP such dividends can only be recognized when declared by the board and may not be accreted ratably over each fiscal year. In addition, because the governing documents underlying the SCA
  Series A Preference Shares provide for semi-annual dividends, dividends will only be recognized during the first and third quarters of each fiscal year, if declared by the Board of Directors. During
  the three months ended September 30, 2007 a semi-annual dividend of $8.4 million on the SCA Series A Preference Shares was declared July 31, 2007 by our Board of Directors and paid on October
  1, 2007 to shareholders of record of the SCA Series A Preference Shares on September 28, 2007. See Offering of Series A Perpetual Non-Cumulative Preference Shares.
Discussion of Consolidated and Segment Results of Operations for the Nine Months Ended September 30, 2007 Compared to the Nine Months Ended September 30, 2006
Summary Discussion of Consolidated Results of Operations
Comparison of nine months ended September 30, 2007 to nine months ended September 30, 2006. Net loss available to common shareholders for the nine months ended September 30, 2007 was
  $26.7 million, a decrease of $108.2 million from net income of $81.5 million reported during the same period in 2006. Net loss for the nine months ended September 30, 2007 included $1.5 million of
  net realized losses on investments, as compared to net realized losses of approximately $16.6 million recorded during the same period in 2006. In addition, also included in net loss available to
  common shareholders for the nine months ended September 30, 2007 was approximately $172.1 million of net unrealized losses on credit derivatives, as compared to net unrealized losses on credit
  derivatives of $6.8 million recorded in the comparable period in 2006.
The decrease in net income available to common shareholders of $108.2 million for the nine months ended September 30, 2007, as compared to the same period in 2006, was primarily driven by:
  (i) higher net unrealized losses on credit derivatives of $165.3 million, resulting primarily from widening credit spreads on assets referenced in our in-force portfolio of credit derivatives, particularly
  subprime mortgage loan assets, which exist in our guarantees of senior triple-A high-grade structured finance CDOs, (ii) higher operating expenses of $20.8 million resulting primarily from increased
  compensation, costs associated with an increase in the volume of our credit default swap business (which are not deferred under GAAP), and continued investment in our infrastructure, (iii) the semi-
  annual dividend on our Series A perpetual non-cumulative preference shares of $8.4 million, and (iv) lower fee income of $2.2 million, offset in part by (v) an increase in net investment income of
  $35.0 million reflecting a significant period over period increase in average invested assets and higher yields on new money investments (vi) higher earned premiums of $19.9 million driven by the
  CDO, public finance and global infrastructure lines of business, which was partially offset by a period over period decrease in refundings and other accelerations of approximately $13.6 million, (vii) a
  decrease in net realized losses on investments of $15.0 million (during the nine months ended September 30, 2006, we reported net realized losses $16.6 million, of which $14.0 million related to an
  impairment charge on investments acquired in satisfaction of a claim), (vii) a decrease in income taxes of $11.7 million driven by an income tax benefit relating to the net loss reported for during the
  current period, (viii) a decrease in dividends on our redeemable preferred shares of $4.2 million due to an amendment in the terms of the redeemable preferred shares in April 2006, (ix) lower net
  losses and loss adjustment expenses of $1.7 million due to favorable development of
46

case reserves, offset in part by an increase in unallocated reserves resulting from the growth of our in-force business, and (x) a decrease in net acquisition costs of $0.9 million primarily driven by an
  increase in ceding commission revenue earned in the current period, as compared to the same period in 2006.
Set forth below is additional information with respect to earned premiums and new business production.
Net premiums earned for the nine months ended September 30, 2007 of $158.7 million included $12.0 million of earnings from refundings of insured obligations and other accelerations (or $11.2
  million, net of accelerated amortization of deferred acquisition costs related to the earnings from such refundings and other accelerations). Net premiums earned for the nine months ended September
  30, 2006 of $138.8 million included $25.6 million of earnings from refundings of insured obligations and other accelerations (or $23.4 million, net of accelerated amortization of deferred acquisition
  costs related to the earnings from such refundings and other accelerations).
Our business production as measured by adjusted gross premiums (which includes upfront premiums written in the period, current installment premiums due on business written in the period and
  expected future installment premiums on business written during the period discounted at 7.0%) totaled $393.5 million for the nine months ended September 30, 2007, an increase of $34.6 million, as
  compared to $358.9 million reported in the comparable period in 2006. The increase was primarily due to higher production in the following lines of business: CDO of $71.3 million, Specialized Risk
  of $14.6 million, Power and Utilities of $9.7 million and Consumer ABS of $9.3 million. These increases were offset in part by lower adjusted gross premium production in the following lines of
  business: Public Finance of $37.8 million and Global Infrastructure of $33.6 million.
Detailed Discussion of Consolidated and Segment Results of Operations by Financial Statement Line Item
Gross Premiums Written
All our gross premiums written are from our financial guarantee insurance segment. Gross premiums written during the period include: (i) premiums received upfront on policies or contracts
  written during the period, (ii) installment premiums due during the period on in-force policies or contracts that were written prior to the period, and (iii) installment premiums due during the period
  on policies and contracts written during the period. Gross premiums written during the period do not include installment premiums due in future periods. Accordingly, our premiums written during
  any period are a function of the type and volume of contracts we write (upfront versus installment), as well as prevailing market prices. Factors affecting market prices include credit spreads, interest
  rates, competition and the volume of new issuances. Generally, financial guarantee insurers are able to charge higher premiums when credit spreads widen. The following table presents, for the
  periods indicated, the amount of gross premiums written attributable to upfront and installment policies and contracts:

  in 2006. The increase was primarily attributable to the $22.9 million favorable variance in structured finance gross premiums written and the $10.8 million favorable variance in international finance
  gross premiums written. The increase in structured finance reflects the growth of our in-force book of our CDO and consumer asset-backed securities businesses. The increase in international finance
  gross premiums written primarily reflects the growth of our Power and Utilities business, which was partially offset by a decline in our Global Infrastructure business. The decrease in public finance
  gross premiums written reflects intense price competition in this sector.
Reinsurance Premiums Assumed
All our reinsurance premiums assumed are from our financial guarantee reinsurance segment. The majority of our financial guarantee reinsurance business is assumed from affiliates of FSAH.

    40,184Reinsurance premiums assumed were $43.6 million for the nine months ended September 30, 2007, an increase of $3.4 million or 8.5%, as compared to $40.2 million recorded in the comparable
  period in 2006. The increase was primarily due to higher international and public finance premiums assumed, partially offset by a small decrease in structured finance assumed premiums. The increase
  in premiums assumed from international finance business was primarily due to transactions in the utilities sector and the increase in premiums assumed from public finance business was primarily due
  to general obligation transactions during the current period. The amount of reinsurance ceded to us depends upon the type and amount of insurance written by primary companies, their capital needs
  and other factors. Such reinsurance is generally structured on a facultative basis.
Ceded Premiums
We manage our in-force business based on single-risk limits to avoid concentration in single names and to mitigate event risk. For transactions that exceed these limits, we cede the excess to
  XLI, XL RE AM, or third-party reinsurers. Through these cessions, we gain greater flexibility to manage large single risks and reduce concentration in specific bond sectors and geographic regions.
  Part of our long-term strategy is to reduce reinsurance to XLI and XL RE AM, and increase our third-party reinsurance relationships. To the extent that we cede a portion of our exposure to one or
  more reinsurance companies, we can reduce our concentration to particular issuers and help to control the diversification of our in-force business. In addition, use of reinsurance can increase our
  capacity to write new business and strengthen our capital adequacy.
The following table presents, for the periods indicated, the amount of premiums ceded to XLI, XL RE AM and other third-party reinsurers:

  million, as compared to $1.2 million recorded in the comparable prior year period. The increase in premiums ceded to other third-party reinsurers during the nine months ended September 30, 2007
  was primarily due to the placement of reinsurance relating to a large structured finance transaction written at the end of 2006. Ceded premiums written to XLI for the nine months ended September
  30, 2006 reflect the return of $26.5 million of premiums in accordance with a commutation effective on the date of our IPO and premiums ceded to XLI for the nine months ended September 30,
  2007 includes $(17.3) million relating to a retrocession of $3.7 billion of par/notional exposure to XLI which was effective July 1, 2007. This transaction was undertaken for capital management
  purposes.

Net Premiums Earned
Financial guarantee upfront premiums are earned in proportion to the expiration of the related risk and financial guarantee installment premiums are earned ratably over the installment period,
  generally one to three months. In addition, when an insured issue is retired early, is called by the issuer or is in substance paid in advance through a refunding accomplished by placing U.S.
  Government securities in escrow, the remaining deferred premium revenue is earned at that time. While reinsurance premiums assumed are earned based on reports from the reinsured companies, we
  believe that the underlying reinsured companies generally follow the revenue recognition policies and practices discussed above.
The following table presents, for the periods indicated, the amount of earned premiums attributable to upfront and installment policies:

  The increase in earned premiums was primarily attributable to higher earned premiums in the financial guarantee insurance and reinsurance segments of $16.2 million and $3.7 million, respectively.
The increase in net earned premium in the financial guarantee insurance segment was primarily attributable to: (i) growth in earned premiums in our CDO, global infrastructure and public
  finance lines of business, and (ii) lower ceded premiums earned, offset in part by, (iii) lower earned premiums from refundings and other accelerations of $16.7 million. Net premiums earned from
  refundings and other accelerations in the financial guarantee insurance segment were $8.3 million and $25.0 million for the nine months ended September 30, 2007 and 2006, respectively.
The increase in net earned premium in the financial guarantee reinsurance segment was primarily attributable to higher earned premiums from refundings and other accelerations. Net premiums
  earned from refundings and other accelerations in the financial guarantee reinsurance segment were $3.8 million and $0.6 million for the nine months ended September 30, 2007 and 2006, respectively.
Net Investment Income
Net investment income was $88.0 million for the nine months ended September 30, 2007, an increase of $35.0 million or 66.0% as compared to $53.0 million in the comparable period in 2006.
  The increase in net investment income was due primarily to higher average invested assets, higher new money yields and a longer portfolio duration. The increase in our average invested assets
  period over period was primarily attributable to operating cash flows since the comparable period in 2006 and the net proceeds from the SCA Series A Preference Shares, which were issued in April
  2007. Also contributing to the increase were the net proceeds from our IPO, cash capital contributions from XL Capital, and the transfer of certain business to us from affiliates of XL Capital in
  connection with our IPO, which was consummated on August 4, 2006.
The following tables present net investment income, average invested assets, the effective yield on our average invested assets, and the average duration of our invested assets as of and for the
  three months ended September 30, 2007 and 2006, respectively. See Investments for information regarding the credit quality of our debt securities.

Net realized losses on investments were $1.5 million for the nine months ended September 30, 2007 as compared to a net realized loss of $16.6 million in the comparable period in 2006. Net
  realized losses during the nine months ended September 30, 2007 included approximately $1.1 million of net realized losses resulting from portfolio dispositions relating to duration, yields and credit
  risk and an other-than-temporary impairment charge of $0.3 million relating to two securities. As a result of the aforementioned dispositions during the nine months ended September 30, 2007, the
  weighted average duration of our investment portfolio increased to 3.4 years at September 30, 2007 from approximately 3.1 at December 31, 2006. During the nine months ended September 30, 2006,
  net realized losses on investments included a $14.0 million impairment charge on certain investments acquired in satisfaction of a claim.
Net Unrealized (Losses) on Credit Derivatives
The Companys derivative financial instruments principally include credit default swaps issued to its customers. Changes in the fair value of credit default swaps attributable to earnings from
  premiums received by us from the issuance of such contracts are recorded in net premiums earned in the unaudited interim consolidated statement of operations. In addition, changes in the fair value
  of credit default swaps attributable to losses from actual and expected payments to counterparties under such contracts are recorded in losses and loss adjustment expenses in the consolidated
  statement of operations, and the remaining components of the change in fair value of credit default swaps, which are attributable to changes in credit spreads, credit quality, interest rates, rates of
  return, and various other factors are recorded in net unrealized losses on credit derivatives. See Critical Accounting Policies and Estimates  Valuation of Credit Default Swaps or Note 3 to the
  Unaudited Interim Consolidated Financial Statements for additional information.
Net unrealized losses on credit derivatives were $172.1 million for the nine months ended September 30, 2007, an increase of $165.3 million, as compared to unrealized losses of $6.8 million
  reported in the comparable period in 2006. The unrealized loss on our credit derivatives resulted primarily from widening credit spreads across most sectors, particularly senior AAA high-grade
  structured finance CDOs, which accounted for $100.7 million of unrealized losses on approximately $15.3 billion of par exposure. In addition, our credit derivatives on CLOs and investment-grade
  corporate synthetic CDOs accounted for unrealized losses of $39.0 million and $13.9 million, respectively, for the nine months ended September 30, 2007, due to widening credit spreads in the specific
  sectors underlying these instruments. With the exception of one of our credit default swaps which guaranteed an international consumer loan asset securitization which was downgraded from AA to
  BBB+ (based on S&P ratings), there were no changes in the credit ratings of the referenced assets underlying our credit default swaps during the nine months ended September 30, 2007.
Net Losses and Loss Adjustment Expenses
Net losses and loss adjustment expenses include current year net losses incurred and adverse or favorable development of prior year net losses and loss adjustment expenses reserves. The

    In connection with the cancellation from inception of certain business ceded by the Company to XLI, XLI assumed the Companys obligation for such loss adjustment expenses  see Note 6 to the consolidated financial statements herein.For the nine months ended September 30, 2007, net losses and loss adjustment expenses were $9.6 million, a decrease of $1.7 million or 15.0%, as compared to $11.3 million reported in the
  comparable period in 2006. The decrease consisted of lower losses and loss adjustment expenses in our financial guarantee insurance and reinsurance segments of $0.8 million and $1.0 million,
  respectively.
Lower net losses and loss adjustment expenses in the financial guarantee insurance segment during the nine months ended September 30, 2007 resulted primarily from favorable development of
  case basis reserves of $3.3 million, offset in part by an increase in unallocated reserves of $1.9 million resulting from the growth of our in-force business. The favorable development of case basis
  reserves was primarily attributable to a case basis reserve relating to an insured obligation supported by subprime mortgage loans which was accelerated, fully paid, and defeased pursuant to the
  exercise of a clean-up call by the sponsor of the securitization in late March 2007 (See Note 9 (c) to the Unaudited Interim Consolidated Financial Statements elsewhere herein for details).
Lower net losses and loss adjustment expenses in the financial guarantee reinsurance segment during the nine months ended September 30, 2007 resulted primarily from favorable development of
  case basis reserves of $1.1 million, offset in part by an increase in unallocated reserves of $0.3 million resulting from the growth of our in-force business.

Capitalized acquisition costs in the financial guarantee insurance segment consist of a portion of compensation, travel and entertainment and marketing costs, as well as premium and excise taxes,
  rating agency fees and legal costs associated with the production of new business. Such capitalized acquisition costs are reduced by ceding commission income on premiums ceded to reinsurers.
Net acquisition costs decreased $0.9 million, or 6.9% in the nine months ended September 30, 2007 as compared to the nine months ended September 30, 2006, primarily driven by decreased
  acquisition costs in the financial guarantee insurance segment of $1.8 million due to a decrease in refunding activity from the year-ago period, partially offset by a decrease in ceding commission
  revenue in the financial guarantee insurance segment of $0.7 million and an increase in acquisition costs in the financial guarantee reinsurance segment of $0.3 million. Accelerated amortization due
  to refundings was $0.5 million in the current period compared to $2.1 million in the year ago period. Excluding the impact of refundings, the decrease of $0.3 million in acquisition costs for the
  financial guarantee insurance segment was due to a decrease in the rate of amortization for certain underwriting years due to an increase in the remaining average life of in-force business written in
  those years, partially offset by higher premium taxes due to an increase in installment premiums written and the amortization of the current underwriting years deferred acquisition costs. The
  decrease in ceding commission revenue in the financial guarantee insurance segment was driven by lower ceded reinsurance. Business previously ceded to XLI was commuted back to the Company
  coincident with the IPO in the third quarter of 2006. As such, we retained more business written as compared to 2006, which resulted in a decrease of ceding commission revenue of 12.8%, from $5.3
  million in 2006 to $4.6 million in 2007, consistent with the significant decrease in ceded premium earned observed from 2006 to 2007 ($19.8 million vs. $16.0 million).
Acquisition costs in the financial guarantee reinsurance segment represent commissions paid to acquire assumed business. Amortization of acquisition costs in the financial guarantee reinsurance
  segment was $4.8 million in the nine months ended September 30, 2007, increasing $0.3 million versus the comparable period in 2006. As acquisition costs are recognized as revenue is earned, the
  increase is consistent with the increase in net premiums earned in the financial guarantee reinsurance segment.
Operating Expenses
Operating expenses were $76.2 million for the nine months ended September 30, 2007, an increase of $20.8 million or 37.5%, as compared to $55.4 million in the comparable period in 2006.
  Operating expenses for the nine months ended September 30, 2007 are comprised of operating expenses of our financial guarantee insurance and reinsurance segments, as well as corporate operating
  expenses, which consist of costs associated with SCA being a stand-alone public company. Operating expenses of our financial guarantee insurance and reinsurance segments aggregated $63.8 million
  for the nine months ended September 30, 2007, an increase of $11.1 million, as compared to $52.7 million in the same period in 2006. The increase in operating expenses of our financial guarantee
  insurance and reinsurance segments resulted primarily from: (i) increased compensation related, in part, to a net increase in the number of our employees, (ii) an increase in the volume of our credit
  default swap business (the costs of which cannot be deferred), and (iii) continued investment in our infrastructure. During the nine months ended September 30, 2007, we reported corporate operating
  expenses of $12.5 million, which included approximately $0.8 million of expense incurred by the Company in connection with the secondary offering of SCA common shares by XL Capital. See
  Organization Background, Initial Public Offering, and Ownership by XL Capital and Note 6 to the Unaudited Interim Consolidated Financial Statements.
Income Tax (Benefit) Expense
For the nine months ended September 30, 2007, we reported an income tax benefit of $9.2 million, a decrease of $11.8 million, as compared to income tax expense of $2.6 million reported in the
  comparable period in 2006. The income tax benefit reported in the current period resulted from the net loss reported during the period, which was primarily driven by the unrealized loss on credit
  derivatives recorded during the quarter. See Note 7 to the Unaudited Interim Consolidated Financial Statements.
Minority Interest  Dividends on Redeemable Preferred Shares
Dividends on redeemable preferred shares were $2.7 million for the nine months ended September 30, 2007, a decrease of $4.2 million, as compared to $6.9 million recorded during the same
  period in 2006.
53

The decrease in dividends on the redeemable preferred shares of XLFA during the nine months ended September 30, 2007, as compared to the comparable period in 2006 was due to an
  amendment of the terms of the preferred shares pursuant to an agreement with the holders of such securities in April 2006 and a change in the stated value of such securities in connection with the
  payment of an extraordinary dividend on March 30, 2007 of $15.0 million.
In accordance with the aforementioned amendment: (i) the participating dividend of the preferred shares, which was in effect prior to 2006, was eliminated, (ii) the stated value of the redeemable
  preferred shares held by FSAH was increased to $54.0 million, and (iii) the fixed dividend rate, which was in effect prior to 2006, was changed to a fixed rate of 8.25%. As a result of the
  aforementioned amendments to the dividend provisions of the preferred shares, dividends on the preference shares were $1.1 million quarterly subsequent to March 31, 2006.
In connection with the extraordinary dividend the stated value of the redeemable preferred shares was reduced by $15.0 million. As a result of the reduction in stated value, dividends on the
  redeemable preferred shares will be $0.8 million quarterly subsequent to March 31, 2007. See Liquidity and Capital Resources  XLFA Redeemable Preferred Shares Extraordinary Dividend.
Dividends on SCA Series A Preference Shares
Because dividends on our SCA Series A Preference Shares are non-cumulative and the declaration of such dividends are subject to the discretion of the Companys Board of Directors, under
  GAAP such dividends can only be recognized when declared by the board and may not be accreted ratably over the each fiscal year. In addition, because the governing documents underlying the
  SCA Series A Preference Shares provide for semi-annual dividends, dividends will only be recognized during the first and third quarters of each fiscal year, if declared by the Board of Directors.
  During the nine months ended September 30, 2007 a semi-annual dividend of $8.4 million on the SCA Series A Preference Shares was declared July 31, 2007 by our Board of Directors and paid on
  October 1, 2007 to shareholders of record of the SCA Series A Preference Shares on September 28, 2007. See Offering of Series A Perpetual Non-Cumulative Preference Shares and Note 13 to the
  unaudited interim consolidated financial statements.
Investments
The Finance and Risk Oversight Committee of our Board of Directors approves our general investment objectives and guidelines. Independent investment managers manage all of our
  consolidated investment portfolios.
Our primary investment objective is the preservation of capital, subject to an appropriate degree of liquidity, and a steady stream of investment income. A secondary objective is to optimize long-
  term returns.
We select our investment managers on the basis of various criteria, including investment style, historical performance, internal controls, operational risk, and the ability to contribute to the
  diversification of our portfolio.
Changes in the valuation of our invested assets reflect changes in interest rates (for example, changes in the level, slope and curvature of yield curves, volatility of interest rates, mortgage
  prepayment speeds and credit spreads) and credit quality. Market risk therefore arises due to the uncertainty surrounding the future valuations of these different assets, the factors that impact their
  values and the impact that this could have on our earnings.
We seek to manage the risks of our investment portfolio through a combination of asset class, industry and security level diversification. In addition, individual security and issuer exposures are
  controlled and monitored at the investment portfolio level via specific investment constraints outlined in our investment guidelines and agreed with the external investment professionals. Additional
  constraints are generally agreed upon with the external investment professionals and may address exposures to eligible securities, prohibited investments/transactions, credit quality and concentrations
  limits. We also have a policy not to invest in any securities that we guarantee.
As of September 30, 2007, our consolidated fixed-income portfolio consisted of debt securities, short-term investments and cash and cash equivalents with a carrying value of $2.3 billion, $0.1
  billion and $0.2
54

billion, respectively. Our debt securities are designated as available for sale in accordance with SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities. The fixed-income
  portfolio is reported at fair value in accordance with SFAS 115, and the change in fair value is reported as part of accumulated other comprehensive income. Short-term investments consist of
  securities with maturities equal to or greater than 90 days but less than one year at time of purchase.
The average duration of our investment portfolio was 3.4 years as of September 30, 2007, as compared to 3.1 years as of December 31, 2006.
Our fixed-income portfolio is exposed to credit and interest rate risk. As of September 30, 2007, the fair value of our fixed-income portfolio was approximately $2.6 billion, as compared to
  approximately $2.2 billion as of December 31, 2006.
The table below shows the percentage of our fixed-income portfolio (excluding cash and cash equivalents) by credit rating as of September 30, 2007:

    As of September 30, 2007 the average credit quality of our fixed-income portfolio was AA+.As of September 30, 2007, the top 10 corporate holdings, which exclude government guaranteed and government sponsored enterprises, represented 11.6% of the total fixed-income portfolio and
  approximately 46.1% of all corporate holdings. As of September 30, 2007, none of our corporate holdings exceeded 2.0% of our total fixed-income portfolio.
Our fixed-income portfolio is exposed to interest rate risk. Interest rate risk is the price sensitivity of a fixed-income security to changes in interest rates. We manage interest rate risk by setting
  duration targets for our investment portfolio, thus mitigating the overall economic effect of interest rate risk. We remain nevertheless exposed to accounting interest rate risk since the assets are
  marked-to-market, thus subject to market conditions, while liabilities are accrued at a static rate. The hypothetical case of an immediate 100 basis point adverse parallel shift in global bond curves as
  of September 30, 2007 would have decreased the fair value of our fixed-income portfolio by approximately 3.4%, or $85.1 million.

Liquidity and Capital Resources
Liquidity Resources
We define liquidity resources to include: our total investments in debt securities, short-term investments, cash and cash equivalents, accrued investment income, the capacity for revolving credit
  loans under our Letter of Credit and Liquidity Facility (see  Letter of Credit and Liquidity Facility below for details), and with respect to XLFA, our soft capital credit facility (see  XLFA Soft
  Capital Facility below for details). At September 30, 2007 and December 31, 2006 our total liquidity resources on a consolidated basis were $3.0 billion and $2.6 billion, respectively.
For the nine months ended September 30, 2007 net cash flows from operating and financing activities were $206.4 million and $217.0 million, respectively. The net cash flows from financing
  activities are net of $30.0 million used to pay dividends to holders of our common and preferred shares. Net cash inflow from operations was driven by new business written and investment income
  and net cash inflow from financing activities was driven from our issuance of Series A Perpetual Non-Cumulative Preference Shares
56

discussed below. Net cash used in investing activities was $421.4 million, reflective of the investment of cash from operations and the preference share offering.
Capital Resources
We target our capital resources to maintain appropriate claims-paying resources to sustain the triple-A claims-paying ratings of our insurance subsidiaries, while minimizing our cost of capital. To
  the extent that the existing capital resources of our operating subsidiaries are insufficient to meet regulatory or rating agency requirements or cover losses, we may need to raise additional funds
  through financings, curtail our insurance subsidiaries growth, or reduce their insured exposure. In addition, any equity or debt financing, if available, may be on terms that are not favorable to us. If
  we cannot obtain adequate capital on favorable terms or at all, our business, operating results, financial condition, and triple-A claims-paying ratings could be adversely affected.
On
    November 5, 2007, Fitch and on November 8, 2007, Moodys Investors Service
    Inc. (Moodys) announced that they would be reevaluating
    the adequacy of the capital position of companies comprising the financial
    guarantee insurance industry in view of recent developments adversely affecting
    the performance of subprime residential mortgage loans. Fitch observed that
    there is a
  moderate probability that the Company may experience pressure in
  its capital cushion under Fitchs updated stress analysis. Fitch noted
  that at the conclusion of its analysis, should a financial guarantors
  capital ratio fall below Fitchs AAA capital guidelines, Fitch
  would expect to place any such insurers financial strength rating on rating
  watch negative with a downgrade to follow if
  a risk mitigation strategy or capital raise is not completed within approximately
  one month. Moodys noted there is a moderate risk of the Company
  falling below Moodys Aaa capital adequacy
  benchmark under a stress scenario. Moodys stated that by the end of November
  2007, it expects to complete its analysis on the financial guarantors capital
  ratios which, for some companies, could result in a rating affirmation, a change
  in outlook, a review for downgrade, or a downgrade.
On November 12, 2007, Fitch announced the downgrade of 352 structured finance CDO transactions, of which two transactions are insured by the Company. Such transactions represent $792
  million in net par insured or approximately 0.5% of SCA total net insured par outstanding. One of the Companys insured transactions of approximately $371 million net par, originally rated AAA by
  Fitch on June 1, 2007, was downgraded to CCC. The other transaction of approximately $421 million net par, originally rated AAA by Fitch on March 29, 2007, was downgraded to BBB. The
  Companys portfolio contains only one other SF CDO rated by Fitch. This transaction of approximately $573 million net par, originally rated AAA by Fitch on June 27, 2006, remains under review.
Downgrades of credits that we insure, such as those made by Fitch on November 12, 2007, will result in higher capital charges to us under the relevant rating agency model or models. If the
  additional amount of capital required to support such exposures is significant, we could be required to raise additional capital, if available, on terms and conditions that may not be favorable to us,
  curtail current business writings, or pay to transfer a portion of our in-force business to generate capital for ratings purposes with the goal of maintaining its triple-A ratings. Among other things, such
  events or goal may not be obtainable, and such events or actions could adversely affect our results of operations and financial condition going forward.
The rating agencies base their analysis of our capital resources on the financial position of our insurance subsidiaries as determined in accordance with statutory accounting practices and, under
  statutory accounting practices, unrealized gains and losses on credit derivatives are not recognized in the earnings or financial position of our insurance subsidiaries, as they are under generally
  accepted accounting practices. .See Critical Accounting Policies and Estimates  Valuation of Credit Default Swaps or Note 3 to the Unaudited Interim Consolidated Financial Statements for
  additional information.
On April 5, 2007, we consummated the sale of $250.0 million of our SCA Series A Preference Shares which were offered for sale pursuant to a private placement. Gross proceeds from the
  offering were $250.0 million, offering costs were $3.4 million, and net proceeds were $246.6 million. The SCA Series A Preference Shares are perpetual securities with no fixed maturity date and, if
  declared by our Board of Directors, will pay a fixed dividend, on a semi-annual basis during the first and third quarters of each
57

fiscal year, at the annualized rate of 6.88% until September 30, 2017. After such date, the SCA Series A Preference Shares, if declared by our Board of Directors, will pay dividends, on a quarterly
  basis, at a floating rate based on three-month LIBOR plus 2.715%. Dividends on the SCA Series A Preference Shares are non-cumulative and the SCA Series A Preference Shares have a liquidation
  preference of $1,000 per preference share.
In connection with the sale of the SCA Series A Preference Shares, we entered into a Replacement Capital Covenant (the Replacement Capital Covenant), whereby we agreed for the benefit
  of holders of one or more designated series of our long-term debt securities that we may issue in the future that (i) we will not redeem, exchange or purchase the SCA Series A Preference Shares
  and (ii) none of our subsidiaries will purchase or exchange the SCA Series A Preference Shares, except, subject to certain limitations, to the extent that the applicable redemption, exchange or
  purchase price does not exceed a specified amount of cash proceeds from the sale of certain specified qualifying replacement capital securities raised during the period commencing on the 180th
  calendar day prior to the date of notice of the redemption or the date of purchase. We have made no decision as to whether, or when, we would issue debt securities that would have the benefit of
  that covenant. While such provisions are in effect, there could be circumstances where we would wish to redeem, exchange or purchase some or all of the SCA Series A Preference Shares but be
  restricted from doing so. The Replacement Capital Covenant may be terminated if (i) holders of at least a majority by principal amount of the then-effective series of covered debt consent or agree
  in writing to terminate the Replacement Capital Covenant, (ii) we no longer have outstanding any indebtedness that qualifies as covered debt or (iii) we no longer have any outstanding SCA Series A
  Preference Shares. In addition, if not earlier terminated, the Replacement Capital Covenant will terminate on September 30, 2047; provided, however, that the September 30, 2047 termination date
  may be extended at our option.
On September 20, 2007, we filed a registration statement with the Securities and Exchange Commission on Form S-4 pursuant to which SCA intends to exchange new registered Non-Cumulative
  Perpetual Preferred Shares for the unregistered SCA Series A Preference Shares (the Exchange Offer). The Exchange Offer is intended to satisfy our obligations under the registration rights
  agreement executed in connection with the issuance of the SCA Series A Preference Shares.
On August 30, 2007, we filed a universal shelf registration statement on Form S-3 with the Securities and Exchange Commission, which became effective on such date and provides for the
  issuance of any or a combination of debt, equity and other forms of securities.
SCA Liquidity
As a holding company, our cash flow consists of dividends from our insurance subsidiaries (XLCA and XLFA), if declared and paid, and investment income on our invested assets, offset by
  expenses incurred for employee compensation and other expenses consisting primarily of costs incurred as a stand-alone public company, including: board of directors fees, directors and officers
  liability insurance, independent auditor fees, stock registrar and listing fees, legal fees, and annual report and proxy production and distribution costs. The payment of dividends or advances from our
  insurance subsidiaries is subject to regulatory restrictions. In addition, the ability of our insurance subsidiaries to conduct business depends upon ratings from independent rating agencies and,
  consequently, they are subject to rating agency imposed restrictions which also may affect their ability to pay dividends or make advances. As a result of the aforementioned regulatory and rating
  agency restrictions, there can be no assurance that our insurance subsidiaries will be able to pay dividends or make advances, or that any dividends or advances paid by our insurance subsidiaries will
  be sufficient to fund our cash requirements or that we will not be required to seek external debt or equity financing to meet our operating expenses.
In the ordinary course of business, we evaluate our liquidity resource needs in light of our expenses, our dividend policy, and the dividend paying ability of our insurance subsidiaries. Based on
  our liquidity resources (as described above) as of September 30, 2007, which aggregated $278.1 million, the income we expect to receive from such liquidity resources, we believe that our holding
  company will have sufficient liquidity to pay its operating expenses and anticipated dividends over the next twelve months. During the nine months ended September 30, 2007, our Board of Directors
  declared quarterly dividends on our common shares which were paid on March 30, 2007, June 29, 2007, and September 28, 2007, respectively,
58

and which aggregated approximately $3.8 million. Also, on July 31, 2007 our Board of Directors declared a semi-annual dividend on the SCA Series A Preference Shares aggregating $8.4 million,
  which was paid on October 1, 2007 to shareholders of record of the SCA Series A Preference Shares on September 28, 2007. In addition, on November 6, 2007 our Board of Directors declared a
  quarterly dividend of $.02 per common share payable on December 31, 2007 to shareholders of record on December 14, 2007. Any future dividends will be subject to the discretion and approval of
  the Board of Directors.
In connection with our IPO, our operating subsidiaries have each agreed that, until the second anniversary of the IPO, each will not declare or pay dividends on its common stock other than to
  fund certain parent holding company operating expenses and debt service requirements and to fund nominal dividends on our common stock. In addition, New York Insurance law contains a test
  governing the amount of dividends that XLCA can pay in any year and, as a result of the application of such test, XLCA cannot currently pay dividends, without notice to, and prior approval from,
  the New York Superintendent. As a U.S. company paying dividends to a Bermuda holding company, XLCAs dividends are subject to a 30% withholding tax rate.
Operating Subsidiaries Liquidity
Liquidity resources at our operating subsidiaries are primarily used to pay their operating expenses, claims, payment obligations with respect to credit derivatives, reinsurance premiums, support in
  force business, and pay dividends to us, as well as in the case of XLCA to make investments from time to time in its subsidiary, XLCA-UK. Our operating subsidiaries principal sources of liquidity
  resources are their portfolio of liquid assets and their net operating cash flow, as well as, in the case of XLFA, a capital facility described under XLFA Capital Facility below. Liquidity resources
  can be affected by changes in interest rates and the amount and timing of loss payments as well as the other factors described under Key Factors Affecting Profitability.
Our operating subsidiaries liquid assets include substantial U.S. Treasury holdings, short-term investments and readily marketable debt securities. These liquidity resources are subject to market
  conditions, regulation and rating agency requirements and we cannot guarantee that they will have sufficient liquidity resources in the future or that they will not have to seek alternative sources of
  liquidity, which may be more expensive than their current liquidity resource options. We believe, however, that our operating subsidiaries sources of liquidity are adequate to meet their anticipated
  needs for at least the next twelve months.
In direct financial guarantee business underwritten by XLCA, our general practice is not to agree to ratings-based triggers which require the mandatory posting of collateral or which would
  otherwise have a material adverse impact on our liquidity position. The few transactions which have ratings-based triggers usually require downgrades of several notches before such triggers are
  breached. Typical consequences for breach of such ratings-based triggers may include (a) loss or sharing of our voting/control rights or (b) optional termination by the counterparty which, if exercised,
  generally results in the loss of future premium. In many instances, these consequences can be cured by certain corrective actions taken by the Company at its option within stipulated time periods
  (with limited exceptions, usually 20 to 30 days).
Our inwards reinsurance agreements generally contain ratings-based triggers whereby if XLFA is downgraded to a level of AA+ to A+, depending upon the reinsurance agreement, the
  primary insurer has the right, but not the obligation, to terminate the agreement and take back generally all or a fixed percentage of all transactions under a given reinsurance agreement. XLFA may
  generally, but is not obligated to, provide collateral to an extent which gives the primary insurer the ability to obtain full financial credit for our reinsurance. In addition, the primary insurer may also
  have the option to increase the ceding commission to a prearranged level in line with the rating of XLFA after the downgrade.
XLCA
Cash Flows.XLCA reported net cash (used in) operating activities of ($1.8) million for the nine months ended September 30, 2007 compared to $44.3 million of net cash provided by operating
  activities in the comparable period in 2006. Net cash provided by operating activities decreased by $46.1 million. The decrease in XLCAs cash flow from operations is primarily due to: (i) slightly
  lower business production (particularly in the public finance sector), as compared to the comparable prior year period,
59

and (ii) a higher proportion of installment business, as compared to upfront business, during the nine months ended September 30, 2007, as compared to the comparable period in 2006, offset in part
  by (iii) XLCAs higher retention of business resulting from the change in its quota share arrangement XLFA, whereby effective July 1, 2006 XLCA began ceding up to 75% of its business to XLFA,
  as compared with 90% prior thereto.
XLCA reported net cash used in investing activities was $41.5 million and $28.4 million for the nine months ended September 30, 2007 and 2006, respectively. Cash used in investing activities is
  primarily a result of investing cash generated from operating activities  see Liquidity Resources above.
As of September 30, 2007 and December 31, 2006, XLCA had readily marketable debt securities and short-term investments with a carrying value of $383.1 million and $347.2 million,
  respectively. In addition, at those dates, approximately 99.9% of XLCAs fixed income portfolio was rated A or higher.
XLFA
Cash Flows.XLFA reported net cash provided by operating activities of $198.8 million for the nine months ended September 30, 2007 compared to $215.0 million in the comparable period in
  2006. Net cash provided by operating activities decreased by $16.2 million.
XLFA reported net cash used in investing activities was $373.8 million and $357.3 million for the nine months ended September 30, 2007 and 2006, respectively. Cash used in investing activities is
  primarily a result of investing cash generated from operating activities and financing activities  see Liquidity Resources above.
XLFA reported net cash provided by financing activities was $207.3 million and $187.3 million for the nine months ended September 30, 2007 and 2006, respectively. The current year net inflow
  reflects the contribution of $225.0 million of net proceeds from the issuance of SCA Series A Preference Shares, partially offset by dividends paid to holders of the redeemable preferred shares of
  XLFA.
As of September 30, 2007 and December 31, 2006, XLFA had readily marketable debt securities and short-term investments with a carrying value of $2.0 billion and $1.6 billion, respectively. In
  addition, at those dates, approximately 99.4% and 99.7% of XLFAs fixed income portfolio was rated A or higher.
Letter of Credit and Liquidity Facility
On August 4, 2006, we and certain of our subsidiaries entered into an aggregate $500 million, five-year letter of credit and revolving credit facility (the Facility) with a syndicate of banks, for
  which Citibank N.A. is the administrative agent. The Facility provides for letters of credit of up to $250 million and up to $250 million of revolving credit loans with the aggregate amount of
  outstanding letters of credit and revolving credit loans thereunder not to exceed $500 million.
Interest and fees payable under the Facility shall be determined based upon certain spreads over defined benchmarks, principally LIBOR. The commitments under the Facility will expire on, and
  amounts borrowed under the Facility may be borrowed, repaid and reborrowed from time to time until, the earlier of (i) the date that is five years after the closing date of the Facility and (ii) the
  date of termination in whole of the commitments upon an optional termination or reduction of the commitments by SCA, XLCA and XLFA or upon an event of default.
The Facility contains financial covenants that require that we at any time (a) prior to August 4, 2008, maintain a minimum net worth (defined as total shareholders equity before accumulated
  other comprehensive income and excluding the effect of any adjustments required under Statement of Financial Accounting Standards No. 133) of $857.4 million, (b) after August 4, 2008, maintain a
  minimum net worth equal to the greater of (1) $857.4 million or (2) an amount equal to 65% of the consolidated net worth as of the end of the then most recent fiscal year or fiscal quarter of SCA
  for which financial statements shall have been delivered, and (c) maintain a maximum total funded debt-to-total capitalization ratio of 30%. At September 30, 2007, our net worth, as calculated by
  the Company in accordance with the Facility, was $1,770.4 million and we had no debt outstanding. The Facility also contains certain covenants, including restrictions on mergers, acquisitions and
  other business consolidations; the sale of assets; incurrence of indebtedness; liens on our assets; and transactions with affiliates. In addition, the Facility contains certain customary provisions regarding
  events of default, including payment defaults, breaches of representations
60

and warranties, covenant defaults, cross-default and cross-acceleration to certain other indebtedness, certain events of bankruptcy and insolvency, material judgments, certain events under the
  Employee Retirement Income Security Act of 1974, as amended, and changes of control.
As of September 30, 2007, we had letters of credit outstanding under the Facility of $176.7 million, which were established for the benefit of primary insurance companies reinsured by the
  Company, as explained below. No revolving loans have been drawn by us under the Facility since its inception. For the three and nine months ended September 30, 2007, we incurred expenses of
  $0.1 million and $0.4 million under the Facility. In the comparable prior period in 2006, XL Capital had drawn letters of credit under its credit facility with a syndicate of commercial banks for the
  benefit of primary companies reinsured by us. For the three and nine months ended September 30, 2006, we incurred expenses of $0.1 million and $0.1 million related to letters of credit drawn by XL
  Capital for the benefit of primary companies reinsured by us.
Primary insurers may require collateral or letters of credit so that they can receive reinsurance credit under certain U.S. state laws. In addition, under certain of our reinsurance treaties, we may
  be required to provide collateral or letters of credit in favor of its ceding insurers in the event of a downgrade of our credit ratings or other event which would diminish the credit provided by our
  reinsurance to such ceding insurers.
Ceded Reinsurance Recoverables
We manage our in-force portfolio of guaranteed obligations based on, and to comply with, regulatory and rating agency single-risk limits and internal credit guidelines. Single-risk limits are
  designed to avoid concentration in single names and to mitigate event risk and are calculated as a percentage of capital. For transactions that exceed these limits or guidelines, we will cede the excess
  to XLI, XL RE AM, or other third-party reinsurers. Generally, all such reinsurance is structured as facultative quota share reinsurance in which the reinsurer is liable to us for its quota share of the
  applicable policies that we issue, regardless of when the loss occurs. Accordingly, related loss reserves, including unallocated loss reserves, are ceded in accordance with such contracts. Through these
  facultative cessions, we gain greater flexibility to manage large single risks and reduce concentration in specific bond sectors and geographic regions. Part of our strategy is to reduce reinsurance to
  XLI and XL RE AM, and increase our third-party reinsurance relationships. To the extent that we cede a portion of our exposure to one or more reinsurance companies, we can reduce our
  concentration to particular issuers and help to control the diversification of our credit portfolio. In addition, use of reinsurance can increase our capacity to write new business and strengthen our
  capital adequacy ratios.
As of September 30, 2007 and December 31, 2006, we had $65.8 million and $70.8 million in reinsurance recoverables from our reinsurers relating to specific case reserves. The following table
  presents, by reinsurer, the amount of our in-force principal exposure ceded to reinsurers as of September 30, 2007 and December 31, 2006:

XLFA Capital Facility
In December 2004, XLFA entered into a put option agreement and an expense reimbursement agreement (the Asset Trust Expense Reimbursement Agreement) with Twin Reefs Asset Trust
  (the Asset Trust). The put option agreement provides XLFA with the irrevocable right to require the Asset Trust at any time and from time to time to purchase XLFAs non-cumulative perpetual
  Series B preferred shares with an aggregate liquidation preference of up to $200 million. There is no limit to the number of times that XLFA may exercise the put option, redeem the Series B
  preferred shares from the Asset Trust and exercise the put option again. XLFA is obligated to reimburse the Asset Trust for certain fees and ordinary expenses. To the extent that any Series B
  preferred shares are put to the Asset Trust and remain outstanding, a corresponding portion of such fees and ordinary expenses will be payable by XLFA pursuant to the asset trust expense
  reimbursement agreement. The put option agreement is perpetual but would terminate on delivery of notice by XLFA on or after December 9, 2009, or under certain defined circumstances, such as
  the failure of XLFA to pay the put option premium when due or bankruptcy. The premium payable by XLFA is the sum of certain trustee and investment managers expenses, the distribution of
  income paid to holders of the pass-through trust securities, less the investment yield on the eligible assets purchased using the proceeds originally raised from the issuance of the pass-through
  securities. The eligible securities (which are generally high-grade investment securities) are effectively held in trust to be used to fund the purchase of any Series B preferred shares upon exercise of
  the put. The put option has not been exercised since the inception of the facility.
XLFA Redeemable Preferred Shares Extraordinary Dividend
On February 27, 2007, the Board of Directors of XLFA approved: (i) an extraordinary dividend of $15.0 million on its Series A Redeemable Preferred Shares, and (ii) a reduction in the stated
  value of the remaining outstanding Series A Redeemable Preferred Shares by a corresponding amount. Payment of the extraordinary dividend and the reduction in the stated value of the Series A
  Redeemable Preferred Shares occurred on March 30, 2007. This transaction was accounted for as a redemption of the preferred shares. As a result of the reduction in stated value, dividends on the
  Series A Redeemable Preferred Shares will be $0.8 million quarterly subsequent to March 31, 2007.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Quantitative and qualitative disclosure regarding our exposures to market risk, as well as our objectives, policies and strategies relating to the management of such risks, is set forth in our Annual
  Report on Form 10-K, which was filed with the Securities and Exchange Commission on March 15, 2007. Our relative sensitivity to changes in fair value from interest rates and equity prices at
  September 30, 2007 is not materially different from that presented in such report.
ITEM 4. CONTROLS AND PROCEDURES
Not Applicable. See Item 4T. Controls and Procedures below.
ITEM 4T. CONTROLS AND PROCEDURES
Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures
The Company carried out an evaluation, under the supervision and with the participation of the Companys management, including the Chief Executive Officer and Chief Financial Officer, of the
  effectiveness of disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended, as of the end of the period covered
  by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures are effective to provide reasonable assurance
  that all material information relating to the Company required to be filed in this report has been made known to them in a timely fashion.
Changes in internal control over financial reporting
There was no change in the Companys internal control over financial reporting, that occurred during the period covered by this quarterly report that materially affected, or is reasonably likely to
  materially affect, the Companys internal control over financial reporting.

PART IIOTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
In the normal course of business, we are subject to claims and litigation. While the outcome of any such claims or litigation are inherently unpredictable, we believe that the ultimate resolution of
  these matters will not, individually or in the aggregate, result in a material adverse impact on our financial condition, results of operations or cash flows.
ITEM 1A. RISK FACTORS
Risks Associated with Recent Adverse Developments in the Credit Markets.The Company is exposed to risks associated with the deterioration in the credit markets. Recently, credit spreads
  across most bond sectors have widened reflecting broad concerns of potential credit erosion in U.S. residential mortgage loans, particularly to subprime borrowers, that are contained in the residential
  mortgage-backed securities (RMBS) and collateralized debt obligations of asset-backed securities (ABS CDOs) it insurers or reinsurers. Subprime residential mortgage loans originated in years
  subsequent to 2005 are performing significantly worse than similar loans made prior to 2005. While the Company has sought to underwrite RMBS and ABS CDOs with levels of subordination
  designed to protect it from loss in the event of poor performance on the underlying collateral, no assurance can be given that such levels of subordination will prove to be adequate to protect the
  Company from material losses in view of the significantly higher rates of delinquency, foreclosure and loss currently being observed among residential homeowners, especially subprime borrowers.
Transactions within the Companys insured RMBS and CDO portfolios also may be downgraded, placed on watch or subject to other actions by the three rating agencies that have granted the
  Company its triple-A claims-paying ratings. Such ratings actions could require the Company to maintain a material amount of additional capital to support the exposures it has insured and reinsured.
  This could cause the Company to: (i) have to raise additional, if available, capital on terms and conditions that may be unfavorable, (ii) curtail the production of new business, or (iii) pay to reinsure
  or otherwise transfer certain of its risk exposure. The Company regards its triple-A ratings as fundamental to the execution of its business plan and the loss of one or more of its triple-A ratings
  could materially impair its ability of continue to execute that plan.
On November 5, 2007, Fitch, Inc. (Fitch) and on November 8, 2007, Moodys Investors Service Inc. (Moodys) announced that they would be reevaluating the adequacy of the capital position
  of companies comprising the financial guarantee insurance industry in view of recent developments adversely affecting the performance of subprime residential mortgage loans. Fitch observed that
  there is a moderate probability that the Company may experience pressure in its capital cushion under Fitchs updated stress analysis. Fitch noted that at the conclusion of its analysis, should a
  financial guarantors capital ratio fall below Fitchs AAA capital guidelines, Fitch would expect to place any such insurers financial strength rating on rating watch negative with a downgrade to
  follow if a risk mitigation strategy or capital raise is not completed within approximately one month. Moodys noted there is a moderate risk of the Company falling below Moodys Aaa capital
  adequacy benchmark under a stress scenario. Moodys stated that by the end of November 2007, it expects to complete its analysis on the financial guarantors capital ratios which, for some
  companies, could result in a rating affirmation, a change in outlook, a review for downgrade, or a downgrade.
On November 12, 2007, Fitch announced the downgrade of 352 structured finance CDO transactions, of which two transactions are insured by the Company. Such transactions represent $792
  million in net par insured or approximately 0.5% of the Companys total net insured par outstanding. One of the Companys insured transactions of approximately $371 million net par, originally
  rated AAA by Fitch on June 1, 2007, was downgraded to CCC. The other transaction of approximately $421 million net par, originally rated AAA by Fitch on March 29, 2007, was downgraded to
  BBB. The Companys portfolio contains only one other SF CDO rated by Fitch. This transaction of approximately $573 million net par, originally rated AAA by Fitch on June 27, 2006, remains
  under review.

Downgrades of credits that we insure, such as those made by Fitch on November 12, 2007, will result in higher capital charges to the Company under the relevant rating agency model or models.
  If the additional amount of capital required to support such exposures is significant, the Company could be required to raise additional capital, if available, on terms and conditions that may not be
  favorable to the Company, curtail current business writings, or pay to transfer a portion of its in-force business to generate capital for ratings purposes with the goal of maintaining its triple-A ratings.
  Among other things, such events or goal may not be obtainable, and such events or actions could adversely affect the results of operations and financial condition of the Company going forward.
Risk to our Earnings from Reporting Credit Derivatives at Fair Value.Any event causing credit spreads on an underlying security referenced in a credit derivative in our portfolio to either
  widen or tighten will affect the fair value of the credit derivative and may increase the volatility of our earnings. Derivatives are required to be reported at fair value in accordance with generally
  accepted accounting principles, with changes in fair value during the period included in earnings. Accordingly, our earnings will be affected by fair valuing such derivatives and could be subject to
  additional volatility, including losses. See Managements Discussion and Analysis of Financial Condition and Results of OperationsCritical Accounting Policies and EstimatesValuation of Credit
  Default Swaps.
Common events that may cause credit spreads on an underlying municipal bond or pool of corporate securities referenced in a credit derivative to fluctuate include changes in the state of
  national or regional economic conditions, industry cyclicality, changes to a companys competitive position within an industry, management changes, changes in the ratings of the underlying security,
  movements in interest rates, default or failure to pay interest or any other factor leading investors to revise expectations about the issuers ability to pay principal and interest on its debt obligations.
  Similarly, common events that may cause credit spreads on an underlying structured security referenced in a credit derivative to fluctuate may include the occurrence and severity of collateral
  defaults, rating changes, changes in interest rates or underlying cash flows or any other factor leading investors to revise expectations about the sufficiency of the applicable collateral or the ability of
  the servicer to collect payments on the underlying assets sufficient to pay principal and interest when due.
