Q06

NOTES TO FINANCIAL STATEMENTSNote 1 - Summary of Significant Accounting Policies

A. Accounting Practices

The accompanying financial statements of Ambac Assurance Corporation (the "Company" or "Ambac Assurance“) have been prepared on the basisof accounting practices prescribed or permitted by the State of Wisconsin Office of the Commissioner of Insurance ("Wisconsin InsuranceCommissioner" or “OCI” (which term shall be understood to refer to such office as regulator of Ambac Assurance and to the Commissioner ofInsurance for the State of Wisconsin as rehabilitator of the Segregated Account of Ambac Assurance (the “Rehabilitator”), as the contextrequires)).

OCI recognizes statutory accounting practices prescribed or permitted by the State of Wisconsin for determining and reporting the financialcondition and results of operations of an insurance company for determining its solvency under Wisconsin Insurance Law. The NationalAssociation of Insurance Commissioners ("NAIC") Accounting Practices and Procedures manual ("NAIC SAP") has been adopted as a componentof prescribed practices by the State of Wisconsin.

OCI has prescribed an accounting practice that differs from NAIC SAP. Paragraph 7 of Statement of Statutory Accounting Principles No. 60“Financial Guaranty Insurance” (“SSAP 60”) allows for a deduction from loss reserves for the time value of money by application of a discountrate equal to the average rate of return on the admitted assets of the financial guaranty insurer as of the date of the computation of the reserve. Thediscount rate shall be adjusted at the end of each calendar year. Additionally, in accordance with paragraph 7 of Statutory Accounting PrinciplesNo. 5R “Liabilities, Contingencies and Impairments of Assets - Revised”, Ambac Assurance records probable losses on its subsidiaries for which itguarantees their obligations, using a discount rate equal to the average rate of return on its admitted assets. The Company’s average rate of returnon its admitted assets at December 31, 2012 was 8.01%. OCI has directed the Company to utilize a prescribed discount rate of 5.10% for thepurpose of discounting both its loss reserves and its estimated impairment losses on subsidiary guarantees. Statutory surplus at June 30, 2013 andat December 31, 2012 was lower by $142,983,945 and $117,602,092, respectively, than if the Company had reported such amounts in accordancewith NAIC SAP. Net income for the six months ended June 30, 2013 and for the year ended December 31, 2012 was lower by $25,381,853 and$19,376,858, respectively, than if the Company had reported such amounts in accordance with NAIC SAP.

OCI has prescribed an additional accounting practice that differs from NAIC SAP. Paragraph 4 of Statement of Statutory Accounting PrinciplesNo. 41 “Surplus Notes” (“SSAP 41”) states that proceeds received by the issuer of surplus notes must be in the form of cash or other admittedassets having readily determinable values and liquidity satisfactory to the commissioner of the state of domicile. Under statutory accountingprinciples, surplus notes issued in conjunction with commutations or the settlement of claims would be valued at zero upon issuance pursuant toparagraph 4, SSAP 41. The Wisconsin Insurance Commissioner has directed the Company to record surplus notes issued in settlement of liabilitiesat full par value upon issuance as in these instances the surplus notes do not represent a contribution of capital, but rather a distribution of valuefrom the common and preferred shareholders of the Company. The surplus notes issued have a claim against surplus senior to the preferred andcommon shareholders. Statutory surplus is not impacted as a result of the prescribed practice as it is a reclassification from unassigned funds tosurplus notes. Net income for the six months ended June 30, 2013 and for the year ended December 31, 2012 was greater by $0 and $789,179,236,respectively, than if the Company recorded the issuance or retirement of surplus notes in accordance with NAIC SAP. The net income difference isthe result of Ambac Assurance’s June 2012 call of surplus notes for $188,446,303, a significant discount to their par values of $789,179,236.

OCI has extended the preceding prescribed practice related to surplus notes to the evaluation of other-than-temporary impairments for AmbacAssurance guaranteed securities held in the investment portfolio. Paragraph 35 of Statement of Statutory Accounting Principles No. 43R”Loan-backed and Structured Securities” states that when an other-than-temporary impairment has occurred, the amount of theother-than-temporary impairment recognized as a realized loss shall equal the difference between the investment’s amortized cost basis and thepresent value of cash flows expected to be collected, discounted at the loan-backed or structured security’s effective interest rate. Under NAICSAP, the present value of cash flows expected to be collected should include the fair value of surplus notes received from the Segregated Accountof Ambac Assurance (the “Segregated Account”), as required under the Segregated Account Rehabilitation Plan (as defined below). TheWisconsin Insurance Commissioner has prescribed an accounting practice that differs from NAIC and has directed the Company to utilize parvalue rather than fair value of these surplus notes in this computation. Statutory surplus at June 30, 2013 and December 31, 2012 was greater by$95,065,335 and $35,761,275, respectively, and net income for the six months ended June 30, 2013 and year ended December 31, 2012 was lowerby $410,907 and $26,097,222, respectively than if the present value of the cash flows expected to be collected included the surplus notes at fairvalue in accordance with NAIC SAP.

OCI has prescribed an additional accounting practice related to the total liabilities and total surplus of the Segregated Account that are reported asdiscrete components of Ambac Assurance’s liabilities and surplus reported in Ambac Assurance’s statutory basis financial statements. Pursuant tothis prescribed practice, the results of the Segregated Account are not included in Ambac Assurance’s financial statements if Ambac Assurance’ssurplus is (or would be) less than $100,000,000 (the “Minimum Surplus Amount”). Maintaining the Minimum Surplus Amount will result in areduction in the liabilities assumed by Ambac Assurance from the Segregated Account. Statutory surplus at June 30, 2013 and year endedDecember 31, 2012 was greater by $0 and $163,687,180, respectively, than if the Company recorded the Segregated Account’s surplus in AmbacAssurance’s statutory basis financial statements in accordance with NAIC SAP. Net income is not impacted as a result of this prescribed practice.

Wisconsin accounting practices for changes to contingency reserves differ from NAIC SAP. Under NAIC SAP, contributions to and releases fromthe contingency reserve are recorded via a direct charge or credit to surplus. Under section 3.08(7)(b) of the Wisconsin Administrative Code,contributions to and releases from the contingency reserve are to be recorded through underwriting income. The Company received permission ofOCI to record contributions to and releases from the contingency reserve and the related tax and loss bond impact, in accordance with NAIC SAP.

Q06.1

NOTES TO FINANCIAL STATEMENTSStatutory surplus is the same using each of these accounting practices. Net income for the six months ended June 30, 2013 and for the year endedDecember 31, 2012 is greater by $45,323,962 and $338,985,112, respectively, than if the Company had reported the contributions to thecontingency reserve in accordance with the Wisconsin Administrative Code.

Ambac Assurance received permission from OCI to report investment holdings of Ambac Assurance insured securities, with coverage underfinancial guaranty policies that have been allocated to the Segregated Account, as a separate invested asset on the balance sheet rather thancombined with other bond investments. This permitted practice only impacts the balance sheet line items and has no impact on the valuation of thesecurities to which it applies or to statutory surplus.

A reconciliation of the Company's net income and statutory surplus between practices prescribed and permitted by the Wisconsin InsuranceCommissioner and NAIC SAP is shown below:

D. Loan-Backed Securities

1. The Company consistently uses the retrospective method to revalue loan-backed securities using current prepayment assumptions. Prepayment assumptions for single class and multi-class loan-backed securities were obtained from publicly available resources. During2013, there were no changes in the methodology utilized by the Company to revalue loan-backed securities.

2. During 2013, the Company recognized other-than-temporary impairment losses (“OTTI losses”) on certain loan-backed securities, includingholdings of Ambac Assurance insured securities, where the present value of cash flows expected to be collected were less than the amortizedcost basis of the securities. For the loan-backed securities still held at June 30, 2013, the total amortized cost immediately prior to the

4. The following table shows all impaired securities (Fair Value is less than cost or Amortized cost) for which an other-than-temporaryimpairment has not been recognized in earnings by length of time that the individual securities have been in a continuous unrealized lossposition at June 30, 2013:

5. Management has determined that the unrealized losses reflected in the table above are temporary in nature as of June 30, 2013 based upon(i) no unexpected principal and interest payment defaults on these securities; (ii) analysis of the creditworthiness of the issuer and financialguarantor, as applicable, and analysis of projected defaults on the underlying collateral; (iii) management has no intent to sell theseinvestments; and (iv) it is not more likely than not that Ambac Assurance will be required to sell these debt securities before the anticipated

Page 9: Ambac Assurance Corporation

Statement for June 30, 2013 of the Ambac Assurance Corporation

Q06.3

NOTES TO FINANCIAL STATEMENTSrecovery of its amortized cost basis. The assessment under (iv) is based on a comparison of future available liquidity from the investmentportfolio against the projected net cash outflow from operating activities and debt service. For purposes of this assessment, availableliquidity from the investment portfolio is comprised of the fair value of securities for which management has asserted its intent to sell plusthe scheduled maturities and interest payments from the remaining securities in the portfolio. To the extent that securities that managementintends to sell are in an unrealized loss position, they would have already been considered other-than-temporarily impaired with theamortized cost written down to fair value. As of June 30, 2013, management has not asserted an intent to sell any securities from itsportfolio. Because the above-described assessment indicates that future available liquidity exceeds projected net cash outflow, it is not morelikely than not that we would be required to sell securities before the recovery of their amortized cost basis.

As of June 30, 2013, for securities that have indications of possible other-than-temporary impairment but which management does not intendto sell and will not more likely than not be required to sell, management compared the present value of cash flows expected to be collected tothe amortized cost basis of the securities to assess whether the amortized cost will be recovered. Receipts were discounted at the effectiveinterest rate implicit in the security at the date of acquisition or for debt securities that are beneficial interests in securitized financial assets,at a rate equal to the current yield used to accrete the beneficial interest. For floating rate securities, future cash flows and the discount rateused were both adjusted to reflect changes in the index rate applicable to each security as of the evaluation date. For RMBS securities thatare insured by Ambac Assurance, future receipts take into account the par value of surplus notes issued as discussed in the prescribedpractice from OCI described above.

E. Repurchase Agreements and/or Securities Lending Transactions

2. For repurchase agreements, in December 2012, Ambac Assurance entered into a repurchase agreement with the Segregated Account, underwhich the Segregated Account loaned Ambac Assurance $100,000,000. The repurchase agreement obligation, matured on February 28, 2013and subsequently renewed to mature on April 30, 2013, accrued interest at a rate of 4.5% per annum. The securities received by theSegregated Account pursuant to the repurchase transaction had been placed in escrow pursuant to the terms of the offer to settle a disputewith the United States Internal Revenue Service (the “IRS”). This repurchase agreement matured on April 30, 2013 and the proceeds wereused in connection with the IRS Settlement (as defined in Note 10). See Note 14 for further details about the IRS Settlement.

Q06.5

NOTES TO FINANCIAL STATEMENTSutilized by the Company on a standalone basis under the rules of the Internal Revenue Code. The TSA addresses certain issues including, butnot limited to, the allocation and use of NOLs by Ambac, Ambac Assurance and their respective subsidiaries.

2. Pursuant to the TSA, to the extent the Company generates taxable income after September 30, 2011, which is offset with NOLs (or theproportionate amount of AMT NOL (as defined below)), it is obligated to make payments, subject to certain credits, to Ambac in accordancewith the following NOL Usage table, where the “Applicable Percentage” is applied to the aggregate amount of federal income tax liability thatwould have been paid if the “Allocated NOLs” were not available:

NOLs identified in E.1. above in excess of $3,650,000,000 are available for use by Ambac, to offset cancellation of indebtedness income, andsettlement of a dispute with IRS. The amount of lost NOLs associated with these two events is $1,876,370,030. To the extent the Companyutilizes Allocated NOLs greater than $3,650,000,000 (or the proportionate amount of AMT NOLs), the Company is obligated to pay Ambac25% of the federal income tax liability that would have been paid if the NOLs were not available.

For the period from September 30, 2011 through June 30, 2013, the Company has generated taxable losses of approximately $165,504,428. Future taxable income shall be offset against this amount prior to payments under the NOL Usage table above.

“AMT NOLs” is defined in the TSA to mean any NOL or NOLs as determined for purposes of the alternative minimum tax provisions of theTax Code, including any adjustments or limitations provided pursuant to Sections 55 through 59 of the Tax Code.

A. Nature of Relationships

Chapter 11 Reorganization of Ambac

On November 8, 2010, Ambac filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code (“Bankruptcy Code”) inthe United States Bankruptcy Court for the Southern District of New York (“Bankruptcy Court”). Ambac, as debtor and debtor-in-possession,filed a Fifth Amended Plan of Reorganization on March 12, 2012 and modified in accordance with orders entered by the Bankruptcy Court onApril 29, 2013 (such Fifth Amended Plan of Reorganization, as so modified, the “Reorganization Plan”). On April 30, 2013, Ambac executed aclosing agreement with the IRS to conclude the settlement of a dispute with the IRS (the “IRS Settlement”), and concurrently paid $1,900,000while the Segregated Account (as defined above) paid $100,000,000 to the United States in connection with such settlement. On May 1, 2013 (the“Effective Date”), the Reorganization Plan became effective and Ambac emerged from bankruptcy.

As provided for in the Reorganization Plan, Ambac’s Amended and Restated Certificate of Incorporation and revised Bylaws became effective onthe Effective Date. Pursuant to the Amended and Restated Certificate of Incorporation of Ambac, Ambac is authorized to issue 150,000,000 sharesof capital stock, consisting of 130,000,000 shares of common stock, par value $0.01 per share and 20,000,000 shares of preferred stock, par value$0.01 per share. In accordance with the Reorganization Plan and the bylaws of the reorganized Ambac, the Board of Directors of Ambac nowconsists of Ambac’s Chief Executive Officer and four other Directors selected by the pre-Effective Date creditors of Ambac.

Pursuant to the Reorganization Plan, Ambac distributed 45,000,000 shares of new common stock on May 1, 2013, consisting of (1) 43,946,750shares to holders of senior debt securities outstanding prior to the Effective Date with claims against Ambac of approximately $1,246,129,000 thatwere discharged in the bankruptcy case; (2) 378,250 shares to holders of allowed general unsecured claims against Ambac in the aggregate amountof approximately $14,328,000 that were discharged in the bankruptcy case; and (3) 675,000 shares to holders of subordinate debt securitiesoutstanding prior to the Effective Date with claims against Ambac of approximately $444,183,000 that were discharged in the bankruptcy case. Ambac has reserved approximately 10,000 shares for possible future distributions to holders of disputed general unsecured claims when suchclaims are resolved. Under the Reorganization Plan Ambac also distributed warrants to (1) the aforementioned holders of allowed generalunsecured claims, which entitle such holders to acquire an additional 42,424 shares of new common stock of Ambac at an exercise price of $16.67per share at any time on or prior to April 30, 2023 and (2) the aforementioned holders of subordinate debt securities, which entitle such holders toacquire an additional 5,004,714 shares of new common stock of Ambac at an exercise price of $16.67 per share at any time on or prior to April 30,2023. The new common stock and warrants were listed on NASDAQ and began trading under the symbols “AMBC” and “AMBCW,”respectively, on May 1, 2013. All such common stock and warrants were issued without registration under the Securities Act of 1933, as amended,or state securities laws, in reliance on Section 1145 of the Bankruptcy Code. The common stock of Ambac in existence prior to the Effective Date

Page 12: Ambac Assurance Corporation

Statement for June 30, 2013 of the Ambac Assurance Corporation

Q06.6

NOTES TO FINANCIAL STATEMENTSwas cancelled on the Effective Date and the holders of such stock did not receive, and will not receive, any distributions under the ReorganizationPlan.

Pursuant to the Mediation Agreement, dated September 21, 2011 (the “Mediation Agreement”) among Ambac, the statutory committee of creditorsappointed by the United States Trustee on November 17, 2010 (the “Creditors’ Committee”), Ambac Assurance, the Segregated Account, theRehabilitator, and the OCI, the terms of which formed an integral part of the Reorganization Plan, Ambac Assurance transferred $30,000,000 (plusaccrued interest) from an escrow account to Ambac on the Effective Date. Additionally, the Segregated Account issued a Junior Surplus Note inthe amount of $350,000,000 to Ambac on the Effective Date in accordance with the Mediation Agreement. No payment of interest on or principalof a Segregated Account Junior Surplus Note may be made until all existing and future indebtedness of the Segregated Account, includingSegregated Account Surplus Notes, policy claims and claims having statutory priority have been paid in full. All payments of principal and intereston Segregated Account Junior Surplus Notes are subject to the prior approval of the OCI. If the OCI does not approve the payment of interest onthe Segregated Account Junior Surplus Notes, such interest will accrue and compound annually until paid.

As of the Effective Date, Ambac was generally discharged and released from all pre-Effective Date debts, liabilities, claims, causes of action andinterests in accordance with the provisions of the Reorganization Plan. Holders of claims and equity interests are also generally barred fromcommencing or continuing any action or proceeding relating to such claims, causes of action or interests. The Reorganization Plan also providesfor broad exculpation and releases of Ambac, Ambac Assurance, the Segregated Account, OCI, the Rehabilitator, the board of directors and boardcommittees of Ambac and Ambac Assurance, all individual directors, officers and employees of Ambac and Ambac Assurance, the Creditors’Committee and the individual members thereof, and each of the respective representatives of such parties, for actions or omissions that occurred onor prior to the Effective Date.

Ambac’s Amended and Restated Certificate of Incorporation limits voting and transfer rights of shareholders in significant ways. Article IVcontains voting restrictions applicable to any person owning at least 10% of Ambac’s common stock so that such person shall not be entitled tocast votes in excess of one vote less than 10% of the votes entitled to be cast by all common stock holders, except as otherwise approved by OCI. Article XII generally prohibits transfers of common stock to the extent that, as a result of such transfer, either (i) the transferee would become thebeneficial owner of 5% or more of Ambac’s outstanding stock or (ii) the percentage stock ownership interest in Ambac of any existing beneficialowner of 5% or more of Ambac’s outstanding stock would be increased. A purported transferee of such a prohibited transfer shall not berecognized as a shareholder of Ambac for any purpose whatsoever in respect of the shares of common stock which comprise the prohibitedtransfer. The Board of Directors of Ambac may grant exceptions to the restrictions of Article XII. Furthermore, on September 27, 2012, theBankruptcy Court entered an order (the “Trading Order”), amending and restating an order entered on November 30, 2010, establishing proceduresfor certain pre-Effective Date transfers or acquisitions of equity interests in and claims (including debt securities) against Ambac. The BankruptcyCourt retains jurisdiction after the Effective Date to enforce the Trading Order with respect to pre-Effective Date violations of the Trading Order.

Segregated Account

On March 24, 2010, Ambac Assurance acquiesced to the request of OCI to establish a segregated account pursuant to Wis. Stat. section 611.24(2).The purpose of the Segregated Account is to segregate certain segments of Ambac Assurance’s liabilities. OCI commenced rehabilitationproceedings with respect to the Segregated Account (the “Segregated Account Rehabilitation Proceedings”) in order to permit the OCI to facilitatean orderly run-off and/or settlement of the liabilities allocated to the Segregated Account pursuant to the provisions of the Wisconsin InsurersRehabilitation and Liquidation Act. Under Wisconsin insurance law, the Segregated Account is a separate insurer from Ambac Assurance forpurposes of the Segregated Account Rehabilitation Proceedings. The Rehabilitator is Theodore Nickel, the Commissioner of Insurance of the Stateof Wisconsin. Ambac Assurance is not, itself, in rehabilitation proceedings.

On October 8, 2010, the Rehabilitator filed a plan of rehabilitation for the Segregated Account (the “Segregated Account Rehabilitation Plan”) inthe Circuit Court of Dane County, Wisconsin in which the Segregated Account Rehabilitation Proceedings are pending (the “RehabilitationCourt”). The Rehabilitation Court confirmed the Segregated Account Rehabilitation Plan on January 24, 2011. The confirmed Segregated AccountRehabilitation Plan also makes permanent the injunctions issued by the Rehabilitation Court on March 24, 2010. The Segregated AccountRehabilitation Plan has not been made effective and is subject to modification. On June 4, 2012, the Rehabilitation Court approved a motion madeby the Rehabilitator to make partial interim policy claim payments to Segregated Account policyholders. In accordance with such approval, onAugust 1, 2012, the Rehabilitator promulgated Rules Governing the Submission, Processing and Partial Payment of Policy Claims in accordancewith the June 4, 2012 Interim Cash Payment Order (the “Policy Claim Rules”). Pursuant to the Policy Claim Rules, effective from August 1, 2012,holders of policies allocated to the Segregated Account were, and continue to be, allowed to submit policy claims for review and partial paymentequating to 25% of the permitted policy claim amount.

In 2010, Ambac Assurance issued a $2,000,000 secured note due in 2050 (the “Secured Note”) to the Segregated Account. Interest on the SecuredNote accrues at the rate of 4.5% per annum, and accrued interest will be added to principal quarterly. The Segregated Account has the ability todemand payment under the Secured Note from time to time to pay claims and other liabilities. The Segregated Account also has the ability todemand payment from time to time under an aggregate excess of loss reinsurance agreement provided by Ambac Assurance (the “ReinsuranceAgreement”) to pay claims and other liabilities after the Secured Note is fully drawn.

On July 11, 2013 the Rehabilitator filed a motion with the Rehabilitation Court seeking approval from the Rehabilitation Court for the SegregatedAccount to make cash payments in excess of 25% of the permitted policy claim amount (“Supplemental Payments”) with respect to 14 policies (the“Identified Policies”) so that cash flow in the related securitization trusts that would have been available to reimburse Ambac Assurance had it paidclaims in full is not diverted to uninsured holders who would not have received such cash flow if claims had been paid in full. The motion also

Page 13: Ambac Assurance Corporation

Statement for June 30, 2013 of the Ambac Assurance Corporation

Q06.7

NOTES TO FINANCIAL STATEMENTSsought authorization for the payment of Supplemental Payments on other policies identified from time to time where similar reimbursements areavailable (together with the Identified Policies, the “SP Policies”). Without making such Supplemental Payments, Ambac Assurance would likelyrealize lower levels of reimbursements as cash flow that would have been available for the benefit of Ambac Assurance in relation to SP Policieswould be lost to such uninsured holders. A hearing on such motion was held on August 2, 2013, following which the Rehabilitation Court grantedsuch motion and entered an order permitting Supplemental Payments to be made with respect to the SP Policies. As a result, it is anticipated thatthe Segregated Account will begin making Supplemental Payments on certain SP Policies in August 2013.

The Rehabilitator has informed Ambac that it intends to seek rulings from the IRS as to certain tax issues associated with potential amendments tothe Segregated Account Rehabilitation Plan. Pursuant to such amendments, surplus notes would not be issued with respect to the unpaid balance ofpermitted policy claims, but such balance would be recorded by the Segregated Account as outstanding policy obligations which would accrueinterest at a rate of 5.1%, likely from the date on which the initial portion (currently 25%) of any such permitted policy claim is paid, compoundedannually until paid (any such outstanding policy obligation, including accrued interest thereon, as such obligation may be adjusted from time totime in accordance with the Segregated Account Rehabilitation Plan, guidelines or rules issued by the Rehabilitator and/or orders of theRehabilitation Court, a “Deferred Amount”). If favorable rulings are received by the Rehabilitator from the IRS as to such tax issues, then theRehabilitator would likely file amendments to the Segregated Account Rehabilitation Plan to provide for Deferred Amounts to be established,rather than for surplus notes to be issued, with respect to the unpaid portion of permitted policy claims. The timing and likelihood of suchamendments to the Segregated Account Rehabilitation Plan are presently unclear, but such amendments could result in a material change to ourfinancial results.

At June 30, 2013, insurance liabilities for policies allocated to the Segregated Account were $6,150,172,103. Pursuant to a prescribed practice, theresults of the Segregated Account are not included in Ambac Assurance’s financial statements if Ambac Assurance’s surplus is (or would be) lessthan the Minimum Surplus Amount. Maintaining the Minimum Surplus Amount will result in a reduction in the liabilities assumed by AmbacAssurance from the Segregated Account. As long as the surplus as regards to policy holders is not less than the Minimum Surplus Amount,payments by Ambac Assurance to the Segregated Account under the Reinsurance Agreement are not capped. At June 30, 2013, AmbacAssurance’s surplus as regards to policyholders is at $393,730,415. In the event that Ambac Assurance does not maintain surplus in excess of theMinimum Surplus Amount, the Segregated Account would experience a shortfall in funds available to pay its liabilities to the extent that suchliabilities exceed amounts available under the Secured Note and the Reinsurance Agreement. Any such shortfall will be a consideration for theRehabilitator in the determination of whether any changes to the Segregated Account Rehabilitation Plan and/or the amount of partial policy claimpayments are necessary or appropriate, or whether to institute general rehabilitation proceedings against Ambac Assurance.

B. Transactions with Affiliates

The Company engaged in the following non-insurance transactions (representing greater than 0.5% of admitted assets) with affiliates.

In February 2013 Ambac Assurance purchased from Ambac Investments, Inc. (“AII”) an investment security for an amount equal to $64,680,570. Such security supported a portion of certain loans made under the Credit Agreement, dated November 12, 2008, by and between ACF, as borrower,and Ambac Assurance, as lender (the “ACF Credit Facility”). AII used the proceeds of such transaction to repay ACF a corresponding amountoutstanding on an outstanding loan from ACF to AII. ACF in turn used such proceeds to pay down a portion of the outstanding balance of theunsecured loan outstanding under the ACF Credit Facility.

In April, the amendment to the Tax Sharing Agreement provides that the increase in NOL from taking a partial bad debt deduction pursuant to theprovisions of IRC 166: LB&I Directive Related to Partial Worthlessness Deduction for Eligible Securities Reported by Insurance Companies willbe shared equally between Ambac and Ambac Assurance.

On May 1, 2013, Ambac Assurance transferred $30,000,000 (plus accrued interest) from an escrow account to Ambac pursuant to the MediationAgreement.

The cumulative unpaid

Q06.8

NOTES TO FINANCIAL STATEMENTSinterest on outstanding surplus notes of $194,864,228 will accrue and compound annually until paid. If OCI approves interest payments on surplusnotes in the future, Ambac Assurance will also be required to pay interest accrued on certain repurchased surplus notes through the call optionexercise dates. The portion of such unpaid interest on repurchased surplus notes is $52,225,000 at June 30, 2013.

Note 14 – Contingencies

The descriptions of matters appearing below in this Note provide an update of those discussed in is Note 14: “Contingencies” in the Company’sAnnual Statement for the year ended December 31, 2012, and should be read in conjunction with the complete descriptions provided in the AnnualStatement.

Ambac’s Chapter 11 Reorganization

Under the Bankruptcy Code, the filing of Ambac’s petition on November 8, 2010 automatically stayed most actions against Ambac. Substantiallyall of Ambac’s pre-petition liabilities were addressed under the Reorganization Plan, if not otherwise addressed pursuant to orders of theBankruptcy Court. The Reorganization Plan was substantially consummated on May 1, 2013, primarily through the distribution of new commonstock and warrants.

In addition to the distributions made on May 1, 2013 pursuant to the Reorganization Plan, Ambac may be required to distribute additional newcommon stock and warrants to claimholders in its Chapter 11 case and will need to make cash payments in respect of any allowed administrativeclaims and professional fees relating to its bankruptcy.

Regulatory Matters

Ambac Assurance has periodically received various regulatory inquiries and requests for information with respect to investigations and inquiriesthat such regulators are conducting. Ambac Assurance has complied with all such inquiries and requests for information.

The Segregated Account Rehabilitation Proceeding

Various third parties have filed motions or objections in the Rehabilitation Court and/or moved to intervene in the Segregated AccountRehabilitation Proceedings. On January 24, 2011, the Rehabilitation Court issued its Decision and Final Order Confirming the Rehabilitator’sPlan of Rehabilitation, with Findings of Fact and Conclusions of Law (the “Confirmation Order”). Notices of appeal from the Confirmation Orderwere filed by various parties, including policyholders. Such appeals are pending.

The Rehabilitation Court entered an order on November 10, 2011 approving the transactions contemplated in the Mediation Agreement and certainparties appealed such order. On March 1, 2013, the Wisconsin Court of Appeals entered an order dismissing this appeal for lack of standing. Thetime for appellants to appeal that order to the Wisconsin Supreme Court has expired and appellants have not made such further appeal. Therefore,the order entered by the Rehabilitation Court approving the transactions contemplated in the Mediation Agreement has become final andnon-appealable.

On June 4, 2012, the Rehabilitation Court issued an order approving Ambac Assurance’s purchase of surplus notes pursuant to the exercise of calloptions (“Surplus Notes Order”). Fannie Mae filed both a Petition for Leave to Appeal and a Notice of Appeal of the Surplus Notes Order. OnMarch 7, 2013, the Wisconsin Court of Appeals denied Fannie Mae’s Petition for Leave to Appeal the Surplus Notes Order and extended FannieMae’s time to respond to the Commissioner’s pending motion to dismiss Fannie Mae’s appeal for lack of jurisdiction and lack of standing toMarch 25, 2013. On March 21, 2013 Fannie Mae filed a Notice of Voluntary Dismissal of Appeal and on April 1, 2013 the Wisconsin Court ofAppeals dismissed Fannie Mae’s appeal of the Surplus Notes Order.

On April 5, 2013, the Rehabilitator filed a motion to confirm the authority of Ambac Assurance to direct Deutsche Bank National Trust Company,as Trustee, to terminate OneWest Bank, F.S.B. (“OneWest”) as servicer for the residential mortgage loans held by two trusts that had issuedsecurities insured by Ambac Assurance, the IndyMac Certificate Trust 2004-2 and the IndyMac Residential Asset-Backed Trust, Series 2004-LH1,and to appoint Green Tree Servicing LLC as the successor servicer. In response to this motion, OneWest filed a Notice of Removal to the UnitedStates District Court for the Western District of Wisconsin on May 5, 2013. The Rehabilitator filed a motion to remand the proceedings back toWisconsin state court on May 21, 2013 and, on May 23, 2013, advised all interested parties of record that the Notice of Removal filed by OneWesthad created uncertainty as the procedural status of the entire rehabilitation proceeding. On July 8, 2013, the Western District of Wisconsin grantedthe Rehabilitator’s remand motion, remanding the case to the Rehabilitation Court, and invited the Rehabilitator to submit a request for fees and

Page 15: Ambac Assurance Corporation

Q06.9

NOTES TO FINANCIAL STATEMENTScosts. At a hearing on the Rehabilitator’s motion concerning the termination of OneWest as servicer on July 31, 2013, the Rehabilitation Courtgranted the Rehabilitator’s motion confirming Ambac Assurance’s authority to direct the trustee to terminate OneWest as servicer for the two trustsand to appoint Green Tree Servicing LLC as the successor servicer.

On July 11, 2013, the Rehabilitator filed a motion seeking authority to pay more than 25% of certain permitted policy claims, either in one lumpsum or in varying proportions over time, in order to maximize reimbursements payable to Ambac Assurance and increase claims-paying resourcesfor the benefit of all policyholders. At a hearing on August 2, 2013, the Rehabilitation Court issued an order authorizing the Rehabilitator and theSegregated Account to pay such Supplemental Payments on 14 policies identified in the motion and on any other policies where similarreimbursements are available.

Tax Treatment of Ambac Assurance’s CDS Portfolio

On April 3, 2013, Ambac, the Creditors’ Committee, Ambac Assurance, the Segregated Account, OCI and the Rehabilitator submitted to the IRSand the Department of Justice, Tax Division, a letter which modified and supplemented the terms of the offer to settle the dispute between the IRS, on the one hand, and Ambac, the Company and the Segregated Account, on the other hand, and related proceedings. On April 4, 2013, theDepartment of Justice, Tax Division, accepted the offer as supplemented and modified. On April 8, 2013, Ambac filed a motion with the UnitedStates Bankruptcy Court for the Southern District of New York seeking approval of the terms of the IRS Settlement. On April 29, 2013, theBankruptcy Court approved in all respects the IRS Settlement, and authorized and directed Ambac, in part, to effectuate the IRS Settlement and totake any other actions as may be reasonably necessary to consummate the settlement, including, without limitation, the execution of a closingagreement with the IRS, and entry of a stipulation dismissing the IRS adversary proceeding with prejudice. On April 30, 2013, Ambac paid to theUnited States Department of the Treasury $1,900,000 and the Segregated Account paid the United States Department of Treasury $100,000,000.Upon confirmation of payment, Ambac and the Internal Revenue Service entered into a closing agreement on April 30, 2013 which resolved withfinality all federal income tax liability of Ambac (and its subsidiaries) for the 2003 through 2009 tax years and resolved with finality the federalincome tax liability of Ambac (and its subsidiaries) for the 2010 tax year solely with respect to items of income, gain, deductions or loss related tothe credit default swaps (“CDS”) contracts. The closing agreement does not resolve the tax treatment of CDS contracts for tax years subsequent to2010.

On May 7, 2013, following execution of the closing agreement and payment of the settlement consideration by Ambac and the SegregatedAccount, the Bankruptcy Court issued an order dismissing with prejudice the adversary proceeding against the IRS. On the same day, Ambac, theUnited States and the Creditors’ Committee filed a stipulation withdrawing and dismissing with prejudice the motion to withdraw the referencepending before the United States District Court for the Southern District of New York. In accordance with the terms of the settlement, on May 9,2013, the United States moved to dismiss with prejudice the two appeals pending in the Seventh Circuit Court of Appeals and to vacate theopinions and orders of the District Court underlying the appeals it perfected. As part of the IRS Settlement, the Segregated Account and AmbacAssurance agreed to support the United States’ motion. On May 15, 2013, the Seventh Circuit Court of Appeals issued an order directing theUnited States to comply with Circuit Rule 57 by requesting that the District Court indicate whether it is inclined to vacate the orders underlying theappeal. The United States complied with that order and on July 10, 2013, the District Court issued a memorandum stating that it was “inclined tovacate the opinions in the case is returned to [the District Court] for that purpose.” Accordingly, on July 12, 2013, the United States requested thatthe Seventh Circuit Court of Appeals grant its May 9th motion to dismiss the appeal and vacate the underlying orders, or alternatively, to remandthe case to the District Court for that purpose. The Seventh Circuit remanded the matter to the District Court which, by orders dated July 16, 2013,dismissed both cases (10-CV-788 and 11-CV-99) with prejudice and vacated its prior decisions.

It is possible that there could beunfavorable outcomes in these or other proceedings.

For the remaining litigation matters that do not meet the “probable and reasonably estimable” accrual threshold and where no lossestimates have been provided above, management is unable to make a meaningful estimate of the amount or range of loss that could result fromunfavorable outcomes but, under some circumstances, adverse results in any such proceedings could be material to our business, operations,financial position, profitability or cash flows. The Company believes that it has substantial defenses to the claims filed against it in these lawsuitsand, to the extent that these actions proceed, the Company intends to defend itself vigorously; however, the Company is not able to predict theoutcomes of these actions.

Litigation Filed by Ambac Assurance

Ambac Assurance Corporation v. Adelanto Public Utility Authority (United States District Court, Southern District of New York, filed on June 1,2009). On January 11, 2013 the court granted Ambac Assurance’s motion for summary judgment and denied defendant’s motion. At a March 13,2013 conference, the court requested that the parties prepare submissions regarding the amount of damages and fees Ambac Assurance is entitledto recover. Ambac Assurance served its submissions upon the defendant on April 23, 2013, the defendant served its response on June 26, 2013,and Ambac Assurance served its reply on July 23, 2013. A hearing regarding Ambac Assurance’s recovery of damages and fees has been scheduledfor August 26, 2013.

In connection with Ambac Assurance’s efforts to seek redress for breaches of representations and warranties and fraud related to the informationprovided by both the underwriters and the sponsors of various transactions and for failure to comply with the obligation by the sponsors torepurchase ineligible loans, Ambac Assurance has filed various lawsuits:

Ambac Assurance Corporation and The Segregated Account of Ambac Assurance Corporation v. EMC Mortgage LLC (formerly knownas EMC Mortgage Corporation), J.P. Morgan Securities, Inc. (formerly known as Bear, Stearns & Co. Inc.), and JP Morgan Chase Bank,N.A. (Supreme Court of the State of New York, County of New York, filed March 30, 2012 and amended on August 14, 2012).Defendants filed a motion to dismiss the amended complaint on September 28, 2012, which Ambac Assurance opposed on October 26,2012. Oral argument was held on February 21, 2013. On June 13, 2013, the court dismissed Ambac Assurance’s contractual claims butnot its claims for fraudulent inducement or successor liability. On July 8, 2013, Ambac Assurance filed its notice of appeal.Ambac Assurance Corporation and The Segregated Account of Ambac Assurance Corporation v. First Franklin Financial Corporation,Bank of America, N.A., Merrill Lynch, Pierce, Fenner & Smith Inc., Merrill Lynch Mortgage Lending, Inc., and Merrill Lynch MortgageInvestors, Inc. (Supreme Court of the State of New York, County of New York, filed April 16, 2012). Defendants filed a motion todismiss on July 13, 2012, which Ambac Assurance opposed on September 21, 2012. Oral argument was held on May 6, 2013. On July18, 2013 the court dismissed Ambac Assurance’s claims for indemnification and limited Ambac Assurance’s claim for breach ofloan-level warranties to the repurchase protocol, but did not dismiss Ambac Assurance’s other contractual claims or fraudulentinducement claim.Ambac Assurance Corporation and The Segregated Account of Ambac Assurance Corporation v. DLJ Mortgage Capital, Inc. and CreditSuisse Securities (USA) LLC (Supreme Court of the State of New York, County of New York, filed on January 12, 2010).

Countrywide Securities Corp.,Countrywide Financial Corp. (a.k.a. Bank of America Home Loans) and Bank of America Corp. (Supreme Court of the State of NewYork, County of New York, filed on September 28, 2010). On May 28, 2013, Ambac Assurance filed a second amended complaintadding an alter ego claim against Bank of America alleging that, because Bank of America and Countrywide are alter egos of oneanother, Bank of America is responsible for Countrywide’s liabilities to Ambac. The defendants served their answers on July 31, 2013.

Ambac Assurance Corporation and The Segregated Account of Ambac Assurance Corporation v. Capital One, N.A., as successor bymerger to Chevy Chase Bank, F.S.B. (United States District Court for the Southern District of New York, filed on October 24, 2012).Ambac Assurance alleges claims for breach of contract, indemnification, and reimbursement and requested the repurchase of loans thatbreach representations and warranties as required under the contracts, as well as damages. Defendants filed a motion to dismiss onFebruary 6, 2013, which Ambac Assurance opposed in a brief filed on February 20, 2013. The motion was fully briefed and filed onMarch 5, 2013. The court held oral argument on March 7, 2013 and has not yet decided the motion.Ambac Assurance Corporation and The Segregated Account of Ambac Assurance Corporation v.

Note 20 – Fair Value Measurements

The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable toestimate that value:

Bonds and loan-backed securities (collectively “bonds”) and Other Unaffiliated Invested Assets

The estimated fair values represent fair values as determined by the NAIC Securities Valuation Offices (“SVO”). In the event the SVO has notdetermined the fair value of a security, fair value amounts are determined by using independent market sources, when available, and appropriatevaluation methodologies when market quotes are not available. In cases where specific market quotes are unavailable, interpreting market data andestimating market values require considerable judgment by management. Accordingly, the estimates presented are not necessarily indicative of theamount Ambac Assurance could realize in the market.

Short-Term Investments, Cash and Cash Equivalents and Intercompany Loans with Affiliates

The fair values of short-term investments are determined by using independent market sources. The fair value of cash and cash equivalentsapproximates their carrying value. Fair values for intercompany loans with affiliates are valued at amortized cost, net of impairments, ordetermined using appropriate valuation methodologies as no market quotes are available.

Receivables for Securities

The fair values of receivable for securities sold approximate carrying value.

Investment Income Due and Accrued

The fair values of investment income due and accrued approximate carrying value.

Liabilities Allocated to the Segregated Account

The fair value estimate represents a net asset to the Company and is the sum of the present values of expected losses (excluding the effect of futureinstallment premiums, reinsurance or subrogation recoveries which is not allocated to the Segregated Account) for both defaulted andnon-defaulted allocated policies, and claims presented and not yet paid as a result of the Segregated Account Rehabilitation Proceedings. TheCompany and the Segregated Account are a single corporate entity and the estimated fair value below does not include a credit valuationadjustment for the creditworthiness of the Segregated Account.

Key variables are par amounts outstanding, expected term, discount rate, and expected net loss and LAE payments. The risk free rate was utilizedto calculate present values, and net par outstanding is monitored by Ambac Assurance's Surveillance Group. Our fair value estimate also considers

Page 18: Ambac Assurance Corporation

Statement for June 30, 2013 of the Ambac Assurance Corporation

Q06.12

NOTES TO FINANCIAL STATEMENTSan estimated profit margin on net cash flows. This profit margin represents what another financial guarantee insurer would require to assume theliabilities allocated. Given the unique nature of financial guarantees and current state of the industry there is a lack of observable marketinformation to make this estimate. A profit margin of 17% was developed based on yields on Ambac Assurance surplus notes and discussions withthe third-party institutions, including those with valuation and industry expertise.

This methodology is based on management’s expectations of how a market participant would estimate net cash flows. We are aware of a numberof factors that may cause such fair or exit value to differ, perhaps materially. For instance, Ambac Assurance is no longer writing new financialguarantee business and accordingly does not have access to observable pricing data points. Additionally, although the fair value accountingguidance for liabilities requires a company to consider the cost to completely transfer its obligation to another market participant, our primaryinsurance obligation is irrevocable and thus there is no established active market for transferring such obligations. Pursuant to paragraph 14 of theStatement of Statutory Accounting Principles No. 100 “Fair Value Measurements” (“SSAP 100”), a credit valuation adjustment for the Company’screditworthiness has not been incorporated in our current fair value estimate of financial guarantees.

Liabilities Assumed from the Segregated Account

The fair value estimate represents a net asset to the Company and is the excess of the estimated fair value of liabilities allocated from AmbacAssurance over the sum of the estimated fair value of the Segregated Account’s net financial assets. Net financial assets include other investedassets, investment income due and accrued, offset by Ambac Assurance’s obligation to support payments under Surplus Notes.

Under the terms of the Reinsurance Agreement, Ambac Assurance assumes all liabilities in excess of the principal balance of the Secured Note andthe total of all other liquid assets of the Segregated Account, subject to the Minimum Surplus Amount at Ambac Assurance. Since the surplus ofAmbac Assurance is contingent on the activities of Ambac Assurance and its insured book of financial guarantees, there is no guarantee that suchsurplus will exceed the Minimum Surplus Amount for the life of the Reinsurance Agreement and accordingly the value of such reinsurance couldbe reduced. The Company considers Ambac Assurance and the Segregated Account to be a single corporate entity. As such, the estimated fairvalue of the liabilities ceded to Ambac Assurance from the Segregated Account does not include a credit valuation adjustment for AmbacAssurance’s creditworthiness.

Borrowed Money and Interest Thereon

The fair value estimates of borrowed money and interest thereon approximate carrying value and do not reflect credit valuation adjustments for theCompany’s creditworthiness pursuant to paragraph 14 of Statement of Statutory Accounting Principles No. 100 “Fair Value Measurements”(“SSAP 100”).

Liability for Net Financial Guarantees Written

This fair value estimate of financial guarantees is disclosed below on a net basis, and includes direct and assumed contracts written, whichrepresents a net liability to the Company, net of ceded reinsurance contracts, which represents a net asset to the Company. The fair value estimateof financial guarantees is computed by utilizing cash flows calculated at the policy level. Projected net cash flows for each policy included: (i)installment premium receipts, (ii) estimated gross claim payments for both defaulted and non-defaulted policies, and (iii) subrogation receipts forboth defaulted and non-defaulted policies. For ceded reinsurance contracts, projected net cash flows for each policy included: (i) installment cededpremium payments, (ii) ceding commission receipts, (iii) ceded claim receipts, and (iv) ceded subrogation payments. For each individual direct,assumed, and ceded reinsurance contract, the respective undiscounted cash flow components are aggregated to determine if we are in a net asset ornet liability position. For each contract in a net liability position, we estimate the fair value using Libor and subsequently apply a profit margin. This profit margin represents what another market participant would require to assume the financial guarantee contracts. Given the unique nature offinancial guarantees and current state of the industry there is a lack of observable market information to make this estimate. The profit margin wasdeveloped based on discussions with the third-party institutions with valuation expertise, discussions with industry participants and yields onAmbac Assurance surplus notes. The profit margin utilized was 17% at June 30, 2013.

Similar to liabilities allocated to the Segregated Account as discussed above, this methodology is based on management’s expectations of how amarket participant would estimate net cash flows. We are aware of a number of factors that may cause such fair or exit value to differ, perhapsmaterially. For instance, as Ambac Assurances is no longer writing new financial guarantee business, we do not have observable pricing datapoints. Additionally, although the fair value accounting guidance for liabilities requires a company to consider the cost to completely transfer itsobligation to another market participant, our primary insurance obligation is irrevocable and thus there is no established active market fortransferring such obligations. Pursuant to paragraph 14 of SSAP 100, a credit valuation adjustment for the Company’s creditworthiness has notbeen incorporated in our current fair value estimate of financial guarantees.

Fair Value Hierarchy

The Company's financial assets have been classified, for disclosure purposes, based on a hierarchy defined by the SSAP 100. SSAP 100 specifiesa fair value hierarchy based on whether the inputs to valuation techniques used to measure fair value are observable or unobservable. Observableinputs reflect market data obtained from independent sources, while unobservable inputs reflect Company-based market assumptions. Inaccordance with SSAP 100, the fair value hierarchy prioritizes model inputs into three broad levels as follows:

Page 19: Ambac Assurance Corporation

Statement for June 30, 2013 of the Ambac Assurance Corporation

Q06.13

NOTES TO FINANCIAL STATEMENTS• Level 1 – Quoted prices for identical instruments in active markets. Assets typically classified as Level 1 include

US treasury securities, money market funds and mutual funds.

• Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similarinstruments in markets that are not active; and model-derived valuations in which all significant inputsand significant value drivers are observable in active markets. Assets typically classified as Level 2generally include fixed income securities representing municipal, asset-backed and corporateobligations.

• Level 3 – Model derived valuations in which one or more significant inputs or significant value drivers areunobservable. This hierarchy requires the use of observable market data when available. Assets andliabilities classified as Level 3 typically include certain fixed income securities for which quoted pricesare not available, transactions with the Segregated Account, and fair value of financial guarantees.Valuation models require significant Company based assumptions.

When available, the Company generally uses quoted market prices to determine fair value, and classifies such items within Level 1. Because manyfixed income securities do not trade on a daily basis, pricing sources apply available information through processes such as matrix pricing tocalculate fair value. In those cases the items are classified within Level 2. If quoted market prices are not available, fair value is based upon modelsthat use, where possible, current market-based or independently-sourced market parameters. Items valued using valuation models are classifiedaccording to the lowest level input or value driver that is significant to the valuation. Thus, an item may be classified in Level 3 even though theremay be significant inputs that are readily observable.

The determination of fair value for financial instruments categorized in Level 2 or 3 involves significant judgment due to the complexity of factorscontributing to the valuation. Third-party sources from which we obtain independent market quotes also use assumptions, judgments and estimatesin determining financial instrument values and different third parties may use different methodologies or provide different prices for securities. Webelieve the potential for differences in third-party asset pricing levels is particularly significant with respect to residential mortgage-backed andcertain other asset-backed securities held in our investment portfolio due to the low levels of recent trading activity for such securities. As a resultof these factors, the actual trade value of a financial instrument in the market may be significantly different from its reported fair value.

The following table sets forth Ambac Assurance’s financial assets and liabilities that were measured and reported at fair value in the statementof financial position after initial recognition as of June 30, 2013 by level within the fair value hierarchy due to the bonds having a NAICdesignation of 3 or higher and the fair value being lower than amortized cost.

4. The fair values of fixed income securities held by Ambac Assurance that are carried at fair value are based primarily on market prices receivedfrom the SVO, alternative pricing sources with reasonable levels of price transparency or from brokers. Such quotes generally consider avariety of factors, including recent trades of the same and similar securities. These quotes represent the only input to the reported fair value ofLevel 2 fixed income securities. The fair values of other unaffiliated invested assets that are carried at fair value are based on the net assetvalue per share or equivalent (“NAV”), calculated on at least a monthly basis where the NAV is the basis for determining the redemptionvalue of the investment.

Q06.15

NOTES TO FINANCIAL STATEMENTS2013, Ambac Assurance’s surplus is greater than the Minimum Surplus Amount and therefore all of the Segregated Account’s insurance liabilitieswere assumed by Ambac Assurance under the Reinsurance Agreement. In the event that Ambac Assurance does not maintain surplus in excess of theMinimum Surplus Amount, the Segregated Account would experience a shortfall in funds available to pay its liabilities to the extent that suchliabilities exceed amounts available under the Secured Note and Reinsurance Agreement. This shortfall will be a consideration for the Rehabilitatorin the determination of whether any changes to the Segregated Account Rehabilitation Plan and/or the amount of partial policy claim payments arenecessary or appropriate or whether to institute general rehabilitation proceedings against Ambac Assurance.

Pursuant to SSAP 62R, the allocation of insurance policies to the Segregated Account as well as the Reinsurance Agreement has been recorded asretroactive reinsurance since these contracts were executed in connection with a court-ordered rehabilitation of the Segregated Account. Accordingly, the net balances due under these obligations are reported in as a net write-in contra-liability.

Losses incurred of $42,013,420 for the six months ended June 30, 2013 is primarily due to a decrease in expected RMBS subrogation recoveries.

June 30, 2013 loss reserves include $3,752,163,618 of claims that have been presented and not paid by the Segregated Account.

Loss adjustment expenses incurred, a benefit of $5,759,326 for the six months ended June 30, 2013 is primarily due to a decrease in loss adjustmentexpense reserves for certain residential mortgage backed credits.

Total net case basis reserves of $2,896,557,698 at June 30, 2013 are net of $(2,511,308,625) of subrogation recoveries relating to representation andwarranty breaches by RMBS transaction sponsors (discounted at 5.1%). In an effort to better understand the unprecedented levels of delinquencies anddefaults, Ambac Assurance or its counsel engaged consultants with significant mortgage underwriting experience to review the underwritingdocumentation for mortgage loans underlying certain insured RMBS transactions. Transactions which exhibited exceptionally poor performance werechosen for further examination of the underwriting documentation supporting the underlying loans. Factors which Ambac Assurance believes to beindicative of poor performance include (i) high levels of early payment defaults, (ii) significant number of loan liquidations or charge-offs and resultinghigh level of losses, and (iii) rapid elimination of credit protections inherent in the transactions’ structures. With respect to item (ii), “loan liquidations”refers to loans for which the servicer has liquidated the related collateral and the securitization has realized losses on the loan; “charge-offs” refers toloans which have been written off as uncollectible by the servicer, thereby generating no recoveries to the securitization, and may also refer to theunrecovered balance of liquidated loans. In either case, the servicer has taken actions as it has deemed viable to recover against the collateral, and thesecuritization has incurred losses to the extent such actions did not fully repay the borrower’s obligations. Generally, the sponsor of the transactionprovided representations and warranties with respect to the securitized loans, including representations with respect to the loan characteristics, theabsence of fraud or other misconduct in the origination process, and attesting to the compliance of loans with the prevailing underwriting policies. Perthe underlying transaction documents, the sponsor of the transaction is contractually obligated to repurchase, cure or substitute collateral for any loanthat breaches the representations and warranties.

Subsequent to the forensic exercise of examining loan files to ascertain whether the loans conformed to the representations and warranties, we submitnonconforming loans to the sponsor for repurchase. To effect a repurchase, depending on the transaction, the sponsor is obligated to repurchase theloan (a) for loans which have not been liquidated or charged off, either at (i) the current unpaid principal balance of the loan, (ii) the current unpaidprincipal balance plus accrued unpaid interest, or (iii) the current unpaid principal balance plus accrued unpaid interest plus unreimbursed serviceradvances/expenses and/or trustee expenses resulting from the breach of representations and warranties that trigger the repurchase, and (b) for a loan thathas already been liquidated or charged-off, the amount of the realized loss (which in certain cases may exclude accrued unpaid interest).

In cases where loans are repurchased by a sponsor, the effect is typically to offset current period losses and then to increase the over-collateralization ofthe securitization, depending on the extent of loan repurchases and the structure of the securitization. Specifically, the repurchase price is paid by thesponsor to the securitization trust which holds the loan. The cash becomes an asset of the trust, replacing the loan that was repurchased by the sponsor. On a monthly basis the cash received related to loan repurchases by the sponsor is aggregated with cash collections from the underlying mortgages andapplied in accordance with the trust indenture payment waterfall. This payment waterfall typically includes principal and interest payments to the noteholders, various expenses of the trust and reimbursements to Ambac Assurance, as financial guarantor, for claim payments made in previous months. Notwithstanding the reimbursement of previous monthly claim payments, to the extent there continues to be insufficient cash in the waterfall in thecurrent month to make scheduled principal and interest payments to the note holders, Ambac Assurance is required to make additional claim paymentsto cover this shortfall.

While the obligation by sponsors to repurchase loans with material breaches is clear, generally the sponsors have not yet honored those obligations. Ambac Assurance’s approach to resolving these disputes has included negotiating with individual sponsors at the transaction level and in some cases atthe individual loan level and has resulted in the repurchase of some loans. Ambac Assurance has utilized the results of the above described loan fileexaminations to make demands for loan repurchases from sponsors or their successors and, in certain instances, as a part of the basis for litigationfilings. Ambac Assurance has initiated and will continue to initiate lawsuits seeking compliance with the repurchase obligations in the securitizationdocuments.

Ambac Assurance has performed the above-mentioned, detailed examinations on a variety of second-lien and first-lien transactions that haveexperienced exceptionally poor performance. However, the loan file examinations and related estimated recoveries we have reviewed and recorded todate have been limited to only those transactions whose sponsors (or their successors) are believed to have sufficient financial wherewithal to meet therelevant obligations. A total of 38 transactions have been reviewed as of June 30, 2013. While our contractual recourse is generally to thesponsor/subsidiary, rather than to the financial institutional parent, each of these financial institutions has significant financial resources and an ongoing

NOTES TO FINANCIAL STATEMENTSinterest in mortgage finance, and we therefore believe that the financial institution/parent would not seek to disclaim financial responsibility for theseobligations if the sponsor/subsidiary is unable to honor its contractual obligations or pay a judgment that we may obtain in litigation. Additionally, inthe case of successor institutions, we are not aware of any provisions that explicitly preclude or limit the successors’ ability to honor the obligations ofthe original sponsor. In fact, certain successor financial institutions have made significant payments to certain claimants to settle breaches ofrepresentations and warranties perpetrated by sponsors that have been acquired by such financial institutions. As a result, we did not make anysignificant adjustments to our estimated subrogation recoveries with respect to the credit risk of these sponsors or their successors. We believe thatfocusing our loan remediation efforts on large financial institutions first will provide the greatest economic benefit to Ambac Assurance. AmbacAssurance retains the right to review other RMBS transactions for representations and warranties breaches. Since a significant number of othersecond-lien and first-lien transactions are also experiencing poor performance, management is considering expanding the scope of this effort.

Q06.18

NOTES TO FINANCIAL STATEMENTSAmbac Assurance’s loss reserves are based on management’s ongoing review of the financial guarantee insurance portfolio. Active surveillance of theinsured portfolio enables Ambac Assurance’s surveillance group to track credit migration of insured obligations from period to period and updateinternal classifications and credit ratings for each transaction. Non-adversely classified credits are assigned a Class I or Survey List (“SL”) ratingwhile adversely classified credits are assigned a rating of Class IA through Class V. The criteria for an exposure to be assigned an adversely classifiedcredit rating includes the deterioration of an issuer’s financial condition, underperformance of the underlying collateral (for collateral dependenttransactions such as mortgage-backed securitizations), poor performance by the servicer of the underlying collateral and other adverse economic eventsor trends. The servicer of the underlying collateral of an insured securitization transaction is a consideration in assessing credit quality because theservicer’s performance can directly impact the performance of the related issue.

Additional remediation activities applied to adversely classified credits can include various actions by Ambac Assurance. The most common actionsinclude obtaining detailed appraisal information on collateral, more frequent meetings with the issuer’s or servicer’s management to review operations,financial condition and financial forecasts and more frequent analysis of the issuer’s financial statements. Senior management meets at least quarterlywith the surveillance group to review the status of their work to determine the adequacy of Ambac Assurance’s loss reserves and make any necessaryadjustments.

All credits are assigned risk classifications by the Surveillance Group using the following guidelines:

CLASS I – “Fully Performing – Meets Ambac Assurance Criteria with Remote Probability of Claim”

Credits that demonstrate adequate security and structural protection with a strong capacity to pay interest, repay principal and perform as underwritten. Factors supporting debt service payment and performance are considered unlikely to change and any such change would not have a negative impactupon the fundamental credit quality.

SURVEY LIST (SL) – “Investigation of Specific Condition or Weakness Underway”

Credits that require additional analysis to determine if adverse classification is warranted. These credits may lack information or demonstrate aweakness but further deterioration is not expected.

CLASS IA – “Potential Problem with Risks to be Dimensioned”

Credits that are fully current and monetary default or claims-payment are not anticipated. The payor’s or issuer’s financial condition may bedeteriorating or the credits may lack adequate collateral. A structured financing may also evidence weakness in its fundamental credit quality asevidenced by its under-performance relative to its modeled projections at underwriting, issues related to the servicer’s ability to perform, or questionsabout the structural integrity of the transaction. While these credits may still retain an investment grade rating, they usually have experienced or arevulnerable to a ratings downgrade. Further investigation is required to dimension and correct any deficiencies. A complete legal review of documentsmay be required. An action plan should be developed with triggers for future classification changes upward or downward.

CLASS II – “Substandard Requiring Intervention”

Credits whose fundamental credit quality has deteriorated to the point that timely payment of debt service may be jeopardized by adversely developingtrends of a financial, economic, structural, managerial or political nature. No claim payment is currently foreseen but the probability of loss or claimpayment over the life of the transaction is now existent (10% or greater probability). Class II credits may be borderline or below investment grade(BBB- to B). Prompt and sustained action must be taken to execute a comprehensive loss mitigation plan and correct deficiencies.

CLASS III – “Doubtful with Clear Potential for Loss”

Credits whose fundamental credit quality has deteriorated to the point that timely payment of debt service has been or will be jeopardized by adversetrends of a financial, economic, structural, managerial or political nature which, in the absence of positive change or corrective action, are likely toresult in a loss. The probability of monetary default or claims paying over the life of the transaction is 50% or greater. Full exercise of all availableremedial actions is required to avert or minimize losses. Class III credits will generally be rated below investment grade (B to CCC).

CLASS IV – “Imminent Default or Defaulted”

Monetary default or claims payment has occurred or is expected imminently. Class IV credits are generally rated D.

CLASS V – “Fully Reserved”

The credit has defaulted and payments have occurred. The claim payments are scheduled and known, and reserves have been established to fully coversuch claims.
