Ambac provides financial guarantee insurance policies through its principal operating subsidiary, Ambac Assurance Corporation (“Ambac Assurance" or ”AAC") and its wholly owned subsidiary, Ambac Assurance UK Limited (“Ambac UK”). Insurance policies issued by Ambac Assurance and Ambac UK generally guarantee payment when due of the principal and interest on the obligations guaranteed. Ambac also has another wholly-owned subsidiary, Everspan Financial Guarantee Corp. (“Everspan”), which has been in runoff since its acquisition in 1997. The deterioration of Ambac Assurance’s financial condition resulting from losses in its insured portfolio since 2007 has prevented Ambac Assurance and Ambac UK from being able to write new business. The inability to write new business has and will continue to negatively impact Ambac’s future operations and financial results. Ambac Assurance’s ability to pay dividends and, as a result, Ambac’s liquidity, have been significantly restricted by the deterioration of Ambac Assurance’s financial condition, by the rehabilitation of the Segregated Account (as defined below) and by the terms of the Settlement Agreement, dated as of June 7, 2010 (the "Settlement Agreement"), by and among Ambac Assurance, Ambac Credit Products LLC (“ACP”), Ambac and certain counterparties to credit default swaps with ACP that were guaranteed by Ambac Assurance. Ambac Assurance is also restricted in its ability to pay dividends pursuant to regulatory restrictions, the terms of its Auction Market Preferred Shares and the terms of agreements entered into with the Segregated Account. It is highly unlikely that Ambac Assurance will be able to make dividend payments to Ambac for the foreseeable future.
Ambac also provides other financial products through subsidiaries of Ambac Assurance. These products consist of interest rate swaps, funding conduits, and investment agreements (until the first quarter of 2017) that were provided principally to clients that were also provided financial guarantee policies. These financial products have been in active run-off since 2007.
Prior to the second quarter of 2017, Ambac had two reportable business segments: i) the financial guarantee segment, which consisted of financial guarantee insurance policies and credit derivative contracts and ii) the financial services segment which consisted of the other financial products discussed above. With respect to the financial services segment, there were significant swap commutations in June 2017. The remaining interest rate swaps, along with other interest rate derivatives, are managed to economically hedge interest rate risk in the financial guarantee and investment portfolios. The last remaining investment agreement matured in March 2017 and the remaining conduit transactions are not material. The significant wind-down of these financial products, along with the appointment of a new Chief Executive Officer effective January 1, 2017, has resulted in a change in how the Company manages its business. Management now reviews financial information, allocates resources and measures financial performance on a consolidated basis. As a result, beginning with the second quarter of 2017, the Company has a single reportable segment. All prior period amounts and disclosures have been adjusted to reflect the reportable segment change.
Ambac’s primary goal is to maximize stockholder value by executing the following key strategies:
Active runoff of Ambac Assurance and its subsidiaries through transaction terminations, policy commutations, settlements and restructurings that we believe will improve our risk profile, and maximizing the risk-adjusted return on invested assets;
Loss recovery through litigation and exercise of contractual and legal rights;
Improved cost effectiveness and efficiency of the operating platform;
Rationalization of Ambac's and its subsidiaries' capital and liability structures, enabling simplification of corporate governance and facilitating the successful rehabilitation of the Segregated Account (as defined below); and
Selective business transactions offering attractive risk-adjusted returns that, among other things, may permit utilization of Ambac’s tax net operating loss carry-forwards.
Although we are exploring selective business transactions for Ambac, no assurance can be given that we will be able to execute the acquisition or development of any new businesses or assets. In addition, there can be no assurance that we will be able to obtain the financial and other resources that may be required to finance the acquisition or development of new businesses or assets that may permit utilization of Ambac’s tax net operating loss carry-forwards. Due to these factors, as well as uncertainties relating to the ability of Ambac Assurance to deliver value to Ambac, the value of our securities is speculative.
The execution of Ambac’s strategy to increase the value of its investment in Ambac Assurance remains subject to the authority of the Rehabilitator to control the management of the Segregated Account. In exercising such authority, the Rehabilitator will act for the benefit of policyholders, and will not take into account the interests of Ambac. The Rehabilitator's authority includes, but is not limited to, sole discretion over the rate at which the Segregated Account pays claims and the accretion rate on Deferred Amounts. Similarly, by operation of the contracts executed in connection with the establishment, and subsequent rehabilitation, of the Segregated Account, the Rehabilitator retains rights to oversee and approve certain actions taken by or in respect of Ambac Assurance. Opportunities for remediating losses on poorly performing insured transactions

(Dollar Amounts in Thousands, Except Share Amounts)

also depend on market conditions, including the perception of Ambac Assurance’s creditworthiness, the structure of the underlying risk and associated policy as well as other counterparty specific factors. Oversight by the Rehabilitator could impair Ambac’s ability to execute certain of its strategies. Ambac Assurance's ability to commute policies or purchase certain investments may also be limited by available liquidity.
As a result of uncertainties associated with the oversight by the Rehabilitator of the Segregated Account as noted herein, management has concluded that there is substantial doubt about Ambac's ability to continue as a going concern. Ambac’s financial statements as of and for the three and six months ended June 30, 2017 and the year ended December 31, 2016 , are prepared assuming Ambac continues as a going concern and do not include any adjustment that might result from its inability to continue as a going concern.
The Segregated Account
In March 2010, Ambac Assurance established a Segregated Account pursuant to Wisc. Stat. §611.24 (2) (the “Segregated Account”) to segregate certain segments of Ambac Assurance’s liabilities, and the Office of the Commissioner of Insurance for the State of Wisconsin (“OCI” (which term shall be understood to refer to such office as regulator of Ambac Assurance and to refer to the Commissioner of Insurance for the State of Wisconsin as rehabilitator of the Segregated Account (the “Rehabilitator”), as the context requires)) commenced rehabilitation proceedings in the Dane County, Wisconsin Circuit Court (the “Rehabilitation Court”) with respect to the Segregated Account (the “Segregated Account Rehabilitation Proceedings”) in order to permit OCI to facilitate an orderly run-off and/or settlement of the liabilities allocated to the Segregated Account pursuant to the provisions of the Wisconsin Insurers Rehabilitation and Liquidation Act. On October 8, 2010, OCI filed a plan of rehabilitation for the Segregated Account (the “Segregated Account Rehabilitation Plan”) in the Rehabilitation Court. The Rehabilitation Court confirmed the Segregated Account Rehabilitation Plan on January 24, 2011. On June 11, 2014, the Rehabilitation Court approved amendments to the Segregated Account Rehabilitation Plan and the Segregated Account Rehabilitation Plan, as amended, became effective on June 12, 2014. Net par exposure as of June 30, 2017 for policies allocated to the Segregated Account was $10,772,572 . Policy obligations not allocated to the Segregated Account remain in the General Account of Ambac Assurance, and such policies in the General Account are not subject to and, therefore, are not directly impacted by the Segregated Account Rehabilitation Plan.
To pay claims and other liabilities, the Segregated Account has the ability to demand payment from time to time under an aggregate excess of loss reinsurance agreement provided by Ambac Assurance (the “Reinsurance Agreement”). In addition, certain operating and administrative costs and expenses of the Segregated Account are reimbursable by Ambac Assurance pursuant to the Cooperation Agreement, dated as of March 24, 2010, by and between the Segregated Account and Ambac Assurance, as amended (the “Cooperation Agreement”). Ambac Assurance is not obligated to make payments under the Reinsurance Agreement or Cooperation Agreement if its surplus as regards to policyholders is less than $100,000 (the “Minimum Surplus Amount”). As long as the surplus as regards to policyholders is not less than the Minimum Surplus Amount, payments by Ambac Assurance to the Segregated Account under the Reinsurance Agreement and Cooperation Agreement are not capped. At June 30, 2017 , Ambac Assurance’s surplus as regards to policyholders exceeded the Minimum Surplus Amount. In the event that Ambac Assurance does not maintain surplus in excess of the Minimum Surplus Amount, the Segregated Account would experience a shortfall in funds available to pay its liabilities. Any such shortfall would be a consideration for the Rehabilitator in the determination of whether any changes to the Segregated Account Rehabilitation Plan and/or the amount of partial policy claim payments are necessary or appropriate or whether to institute general rehabilitation proceedings against Ambac Assurance.
Rehabilitation Exit Support Agreement
On July 19, 2017, Ambac Assurance and Ambac entered into an agreement (the “Rehabilitation Exit Support Agreement”) with holders or beneficial owners (the “Supporting Holders”) of surplus notes issued by Ambac Assurance and beneficial interests in Deferred Amounts (as defined in the Segregated Account Rehabilitation Plan) of the Segregated Account with respect to a transaction which, subject to the conditions precedent set forth in the Rehabilitation Exit Support Agreement, and if consummated, would generally involve (i) the exchange of certain surplus notes held by holders of surplus notes that elect to participate in a voluntary exchange transaction and (ii) the satisfaction and discharge of all Deferred Amounts, in each case for an effective consideration package comprised of cash and new Secured Notes (as defined below) and certain existing surplus notes and (iii) the exit from rehabilitation of the Segregated Account (the “Rehabilitation Exit Transactions”).
The settlement of the Deferred Amounts and the Segregated Account’s exit from rehabilitation are expected to be realized through the amendment (the “Rehabilitation Plan Amendment”) of the Segregated Account Rehabilitation Plan to be pursued by the Rehabilitator, and a series of transactions which would provide to holders of beneficial interests in Deferred Amounts (other than Ambac, but including Ambac Assurance) a total effective consideration package, in full satisfaction and discharge of each $1.00 of Deferred Amounts (including accretion), of (i) $0.40 in cash, (ii) $0.41 in principal amount of new Secured Notes (as defined below) and (iii) from certain holders of surplus notes, $0.125 currently outstanding surplus notes. Such consideration package would thereby provide a discount of $0.065 (set first against accretion of Deferred Amounts). Ambac would receive $0.91 in principal amount of Secured Notes for each $1.00 of Deferred Amounts (including accretion) that it holds, and would provide a $0.09 discount in full satisfaction and discharge of its Deferred Amount claims. It is anticipated that the Rehabilitator will file a motion in the Rehabilitation Court by no later than October 2, 2017 seeking entry of an order approving the Rehabilitation Plan Amendment. The Rehabilitator has reserved December 12, 2017 through December 14, 2017 for a confirmation hearing on the Rehabilitation Plan Amendment, and November 30, 2017 for a pre-trial hearing.
The Rehabilitation Exit Support Agreement calls for a series of interrelated transactions involving the exchange of certain surplus notes (collectively, the “Exchange Offers”), pursuant to which, for each $1.00 of principal amount outstanding and accrued and unpaid interest thereon,

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
Notes to Unaudited Consolidated Financial Statements
(Dollar Amounts in Thousands, Except Share Amounts)

holders effectively would (i) receive $0.40 in cash, (ii) receive $0.41 in principal amount of Secured Notes, (iii) retain $0.125 in principal amount and accrued and unpaid interest thereon of surplus notes and (iv) provide a discount of $0.065 in principal amount and accrued and unpaid interest thereon. Ambac will not participate in the Exchange Offers and will hold surplus notes issued by the Segregated Account and Ambac Assurance until the Rehabilitation Exit Transactions are consummated and a certain amount of such surplus notes for a time after such transactions are completed, as described below.
As part of the Rehabilitation Exit Transactions, Ambac and Ambac Assurance will seek consents from holders of surplus notes to a waiver and amendment (the “BSA Waiver and Amendment”) of certain provisions of the Settlement Agreement, such consents to be executed by holders of more than 50% in aggregate principal amount of the surplus notes. Holders who participate in the Exchange Offers will be required to deliver their consent to the BSA Waiver and Amendment.
As contemplated by the Rehabilitation Exit Support Agreement and as a portion of the consideration received by holders of beneficial interests in Deferred Amounts (including Ambac Assurance) in satisfaction and discharge of their claims pursuant to the Rehabilitation Plan Amendment and by holders of surplus notes pursuant to the Exchange Offers (as specified above), a newly formed special purpose entity will issue new secured notes (the “Secured Notes”), secured by all assets of the special purpose entity, which include a note issued by Ambac Assurance to the special purpose entity, which note is secured by a pledge of Ambac Assurance’s right, title and interest in up to the first $1,400,000 of proceeds (net of reinsurance) from certain litigations in which Ambac Assurance and the Segregated Account seek redress for breaches of representations and warranties and/or fraud related to residential mortgage-backed securitizations (the “ RMBS Litigations ”). In addition, the note issued by Ambac Assurance to the special purpose entity will be secured by RMBS securities having a market value of not less than $350,000 on the date that is not more than five business days prior to the closing date of the Rehabilitation Exit Transactions. Ambac Assurance will also pledge for the benefit of the holders of Secured Notes (other than Ambac Assurance) the proceeds of any Secured Notes held by AAC from time to time, and will issue a financial guaranty insurance policy to a trustee for the benefit of holders of Secured Notes irrevocably guarantying all principal and interest payments in respect of the Secured Notes as and when such payments become due and owing. Should Ambac Assurance settle any of the RMBS Litigations before the closing of the Rehabilitation Exit Transactions, any proceeds received by Ambac Assurance from any settlement which would have secured the Secured Notes will replace Secured Notes having a face amount equal to the amount of proceeds received that would otherwise be issued.
Following the consummation of the Rehabilitation Exit Transactions and until the earlier of (i) June 8, 2020 and (ii) the date on which at least 25% of the principal amount of Remaining Senior Surplus Notes (as defined the Rehabilitation Exit Support Agreement) are no longer outstanding, Ambac shall hold and not sell Remaining Senior Surplus Notes which, as of June 30, 2017, have an aggregate of $60,000 of principal amount and accrued and unpaid interest outstanding.
The Company may terminate the Rehabilitation Exit Support Agreement upon the occurrence of certain events, including if the Rehabilitation Exit Transactions have not been consummated within 365 days of the signing date of the Rehabilitation Exit Support Agreement.
Supporting Holders that, in the aggregate, beneficially own at least 66 2/3% of the principal amount outstanding under the surplus notes and 66 2/3% of the principal amount of the Deferred Amounts, held by the Supporting Holders as a whole may terminate the Rehabilitation Exit Support Agreement upon the occurrence of certain events, including if (i) within 75 days of signing date of the Rehabilitation Exit Support Agreement, the Rehabilitator has not filed a motion in the Rehabilitation Court seeking entry of the approval order; (ii) the confirmation hearing has not commenced within 180 days of the signing date of the Rehabilitation Exit Support Agreement; and (iii) the Rehabilitation Exit Transactions have not been consummated within 270 days of the Signing Date. In addition if the Rehabilitation Exit Transactions have not been consummated within 365 days of the signing date of the Rehabilitation Exit Support Agreement, each Supporting Holder shall have the right to terminate the Agreement with respect to itself.
Ambac can provide no assurance that any of the termination events described above or in the Rehabilitation Exit Support Agreement will not arise.
The Exchange Offers will be subject to a number of conditions precedent, including, among others, (i) approval by the OCI; (ii) the effectiveness of the Rehabilitation Plan Amendment concurrent with the closing of the Exchange Offers; (iii) participation by 85% of the outstanding principal amount owned by holders of surplus notes (including Ambac and Ambac Assurance) in the Exchange Offers; (iv) receipt of consents of at least a majority of the outstanding aggregate principal amount of the surplus notes (other than surplus notes beneficially owned by Ambac or Ambac Assurance or any of their affiliates) to the BSA Waiver and Amendment; and (v) subject to the approval of the OCI, a one-time current interest payment of approximately $12,500 on the surplus notes outstanding immediately following the effective date of the Rehabilitation Plan Amendment.
The Rehabilitation Plan Amendment is subject to a number of conditions precedent having been satisfied or waived by the Rehabilitator, in his sole discretion, including, among others, (i) the Rehabilitation Plan Amendment will have been approved by the Rehabilitation Court, and such order will have become a final order; (ii) as of the effective date, Ambac Assurance will have sufficient capital and claims-paying resources to effect all of the Rehabilitation Exit Transactions and to exit rehabilitation; (iii) the conditions to consummation of the Exchange Offers will have

(Dollar Amounts in Thousands, Except Share Amounts)

been satisfied or waived in full in accordance with the terms thereof; and (iv) Ambac will have received from the Internal Revenue Service a ruling, in form and substance reasonably satisfactory to the Rehabilitator, Ambac Assurance, and Ambac.
Ambac can provide no assurances that these approvals or consents will be obtained or that the other conditions precedent will be satisfied or waived in a timely manner or at all. Even if the Rehabilitation Exit Transactions are consummated, OCI may impose on Ambac and Ambac Assurance reporting requirements and restrictions on transactions or other activities, which may create additional challenges or obstacles with respect to Ambac Assurance's ability to deliver value to Ambac and Ambac's ability to deliver value to its stockholders.
Tier 2 Commitment
On July 19, 2017, Ambac Assurance also entered into a commitment letter (the “Commitment Letter”) with certain investors (the “Investors”), with respect to the issuance of an aggregate principal amount of $240,000 of senior notes (the “Tier 2 Notes”) secured by Ambac Assurance’s rights, title and interest in the cash and non-cash proceeds (net of reinsurance) above $1,600,000 received in connection with the RMBS Litigations. The Commitment Letter will terminate upon the earliest occurrence of: (i) 365 days from the execution of the Rehabilitation Exit Support Agreement, and (ii) the date on which the Tier 2 Notes are issued. In addition, Ambac Assurance and the Investors have the option to terminate the Commitment Letter following (i) the resolution of Ambac Assurance Corp. et al. v. Countrywide Home Loans, Inc. et al., Index No. 651612/2010 (N.Y. Sup. Ct. N.Y. Cnty.) (Bransten, J.) or (ii) the termination of the Rehabilitation Exit Support Agreement. The issuance of the Tier 2 Notes is subject to a number of conditions precedent including, among others, satisfaction or waiver of the conditions to effectiveness set forth in the Plan Amendment.
The terms, conditions, and timing of the conclusion of the Segregated Account Rehabilitation Proceedings are in the sole discretion of the OCI, and subject to the approval of the Rehabilitation Court. No assurance can be given that Rehabilitation Exit Transactions or issuance of the Tier 2 Notes will be consummated. OCI retains the authority, subject to the approval of the Rehabilitation Court, to address Segregated Account obligations without the agreement of Ambac Assurance or its board of directors. Moreover, even if the Segregated Account Rehabilitation Proceedings could be brought to a successful conclusion, there can be no assurance that any level of capital deemed sufficient by OCI to permit such conclusion will be sufficient to cover all future losses, whether currently anticipated or unanticipated.
Ambac Assurance will seek to further improve its financial condition by continuing to pursue asset monetizations; loss recoveries; restructurings, purchases, modifications or exchanges of certain outstanding obligations; extinguishment or modification of certain contractual restrictions; and/or commuting or reducing insured exposures Separately from or in connection with the actions described above, we may seek to further optimize our capital and corporate structure to unlock shareholder value.
Augusta Funding Limited IV ("Augusta") Commutation
On June 27, 2017, Ambac entered into a termination agreement with various parties, including Augusta, in connection with the commutation of interest rate swaps between Augusta and Ambac's wholly-owned subsidiary, Ambac Financial Services. During the second quarter, Ambac had net settlement payments of approximately $103,592 , including $94,407 under the termination agreement. At March 31, 2017, Ambac had recorded a mark-to-market liability under this swap transaction of $147,035 , resulting in a gain of approximately $43,443 and $42,157 during the three and six months ended June 30, 2017 , respectively. In July 2017, Augusta redeemed its outstanding Ambac-insured debt and accordingly Ambac will recognize approximately $2,600 in accelerated earnings in the third quarter of 2017 relating to this redemption.
Ballantyne Litigation
On March 25, 2017, Ambac UK agreed in principle to a confidential settlement of litigation brought by Ambac UK in the name of Ballantyne Re plc ("Ballantyne") against J.P. Morgan Investment Management Inc. ("JPMIM") relating to the management of Ballantyne’s investment accounts, which were funded with the proceeds of notes issued in 2006 in connection with a structured reinsurance transaction and guaranteed in part by Ambac UK. On April 11, 2017, Ambac UK, Ballantyne and JPMIM signed a settlement agreement. Pursuant to the settlement, Ballantyne received a payment of $325,600 from JPMIM in return for releases of all claims by Ballantyne and Ambac UK. As a result of the settlement, Ambac recognized an incremental benefit through a reduction in losses and loss expenses of approximately $91,600 in the first quarter of 2017. Ambac had previously included an estimated benefit through a reduction of loss and loss expense reserves of approximately $53,000 related to our probability weighted estimate of the value of the litigation. The total $144,600 benefit recognized from the settlement of the litigation will reduce the ultimate Ballantyne claims Ambac UK is expecting to pay and not result in a direct cash payment to Ambac UK.
Puerto Rico
On March 13, 2017, the Financial Management and Oversight Board for Puerto Rico (the "Oversight Board") certified the 10-year Fiscal and Economic Growth Plan ("FEGP") for the Commonwealth of Puerto Rico (the “Commonwealth"). The certified FEGP, among other things, was intended to provide Commonwealth creditors a base from which to progress consensual negotiations under Title VI of the P uerto Rico Oversight, Management and Economic Stability Act ("PROMESA"). However, the certified FEGP implied a 77% discount to all debt service due to be paid by the Commonwealth and its instrumentalities covered by the FEGP over the ten-years of the plan (FY2017-2026). The FEGP did not provide details regarding its underlying assumptions and data, expense definitions, cause of expense growth or accounting adjustments and did


| Ambac Financial Group, Inc. 8 2017 Second Quarter FORM 10-Q |

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
Notes to Unaudited Consolidated Financial Statements
(Dollar Amounts in Thousands, Except Share Amounts)

not include any restructuring proposals. These deficiencies of the FEGP, when combined with the absence of sufficient projected cash flows for debt service, increased the uncertainty of whether successful consensual negotiations can be reached.
On April 28, 2017, the Fiscal Agency and Financial Advisory Authority of Puerto Rico (“FAFAA”) released a restructuring proposal covering General Obligation (“GO”), GO-guaranteed, Puerto Rico Sales Tax Financing Corporations ("COFINA"), Puerto Rico Highways and Transportation Authority ("PRHTA"), Puerto Rico Infrastructure Financing Authority ("PRIFA") and Puerto Rico Convention Center District Authority ("CCDA") bonds. Under the proposal, bondholders would receive a “senior bond” based on amounts expected to be available for debt service under the FEGP and a “cash flow bond” that would allow for additional payments if amounts available for debt service exceeded FEGP forecasts. FAFAA’s proposal further provides that GO and GO-guaranteed bondholders would be offered a maximum recovery of 77% (52% senior bond, 25% cash flow bond), COFINA bondholders would receive a maximum recovery of 58% (39% senior bond, 19% cash flow bond), and PRHTA, CCDA, PRIFA, and Metropolitan Bus Authority bondholders would receive a maximum recovery of 30% (0% senior bond, 30% cash flow bond). Recoveries relating to the cash flow bond component could be lower depending upon future surpluses at the General Fund and future new money GO bond issuances. The proposal was premised only on the cash available for debt service included in the certified FEGP, despite challenges from creditors and repeated calls for a review and adjustment of the assumptions underlying such Plan. Among other infirmities, the proposal lacks textured narrative or economic or financial logic for treating Senior and Junior tranches within the COFINA structure as pari passu obligations and fails to explain how the allocation of cashflow between GO and GO-guaranteed bonds and COFINA bonds was derived. The proposal was not accepted by affected bondholders.
On April 29, 2017, the Commonwealth enacted the Fiscal Plan Compliance Act, also known as Act No. 26 (the “Fiscal Plan Compliance Act” or “Act 26-2017”). Articles 4.01 and 4.02 of Chapter 4 of the Fiscal Plan Compliance Act order all public corporations, agencies and instrumentalities of the Government of Puerto Rico to transfer their revenue surplus to the Commonwealth Treasury, after covering operational expenses and obligations, as per the expense budget recommended by the Office of Management and Budget of Puerto Rico for each fiscal year. Article 4.01 further states that such funds would be considered “available resources” for the Commonwealth and would be deposited in the Commonwealth’s General Fund to meet the liquidity requirements contemplated in the FEGP. Article 4.02 empowers a committee composed of the Executive Director of the Fiscal Agency and Financial Advisory Authority of Puerto Rico, the Secretary of the Puerto Rico Treasury Department and the Executive Director of the Office of Management and Budget of Puerto Rico to determine the amount each public corporation and instrumentality would contribute. Such committee is also empowered to revise the sources of revenue of the public corporations, agencies and instrumentalities and adjust, increase or reduce any of their charges, fees, tariffs and similar revenues, with the objective of complying with the metrics stated in the FEGP.
Article 4.03 of Chapter 4 of Act 26-2017, “Exclusions”, explicitly excludes certain entities from coverage of Articles 4.01 and 4.02, including the University of Puerto Rico, the Public Corporation for the Supervision and Insurance of Cooperatives (COSSEC), and funds from public corporations and entities received by private entities for community-related objectives.
While Article 4.03 does not explicitly exclude COFINA from coverage of such Articles 4.01 and 4.02, as it does with other entities, it does state that the Executive Branch shall be authorized to use the COFINA funds, occasionally, solely as a last alternative, and subject to the filing of a sworn certification before the Legislative Assembly. Such sworn certification, which, according to Article 4.03 shall not be interpreted to give the Executive Branch indefinite use of the COFINA funds, must establish the need, term and amount of funds that will be used to cover significant occasional cash flow deficits to comply with the FEGP. An Explicative Declaration of Act 26-2017 signed by the Governor of Puerto Rico on April 29, 2017 states that because COFINA does not generate surpluses, the dispositions of Chapter 4 are not applicable to COFINA. The Explicative Declaration further states that the Fiscal Plan Compliance Act does not refer to other revenues from public corporations except for those determined by fee adjustments of the corporations specifically included in the FEGP. The statements in the Explicative Declaration appear to contradict the statutory language of Articles 4.01, 4.02 and 4.03, resulting in uncertainty about how the Fiscal Plan Compliance Act will be implemented.
In its Chapter 6, the Fiscal Plan Compliance Act also requires that, commencing July 1, 2017, all special funds and other revenues of dependencies and public corporations must be deposited with the Puerto Rico Treasury. The Puerto Rico Secretary of Treasury is authorized to establish the order of priority for the disbursement of payments chargeable to the special funds and other revenues, in accordance with the approved budget and the Fiscal Plan.
On May 1, 2017, Ambac Assurance sent COFINA a notice of failures to comply with covenants and events of default under COFINA’s bond resolution and enabling legislation. Among other things, Ambac Assurance stated that the Commonwealth had violated its covenant not to limit or restrict the right granted by the Resolution or COFINA’s rights to meet its obligations to its bondholders by enacting the Fiscal Plan Compliance Act; that COFINA had violated its covenant to defend, preserve, and protect the pledge of the Dedicated Sales Tax to COFINA and the rights of COFINA’s bondholders under the Resolution against all claims and demands; and that both covenant violations were incurable and therefore constituted immediate Events of Default under the COFINA resolution. Also on May 1, 2017, the COFINA trustee, Bank of New York Mellon (“BNY”), sent a letter to COFINA and the Puerto Rico Fiscal Agency and Financial Advisory Authority stating that the Fiscal Plan Compliance Act was inconsistent with COFINA’s and the Commonwealth’s covenants under COFINA’s resolution and enabling legislation, and seeking a response detailing any curative action either intended to take. On May 4, 2017, BNY sent COFINA a notice of default arising out of the Fiscal Plan Compliance Act, and stated that the defaults by COFINA and the Commonwealth would be deemed Events of Default under the COFINA resolution if left uncured within 30 days of Ambac’s May 1, 2017 letter noticing the defaults. Later on May 4, 2017, Ambac Assurance, together

(Dollar Amounts in Thousands, Except Share Amounts)

with holders of more than 25% of the senior COFINA bonds, sent a letter to BNY demanding immediate acceleration of all senior bonds issued by COFINA. On May 16, 2017, BNY filed an interpleader action in COFINA’s Title III case against COFINA and certain creditors of COFINA, including Ambac Assurance, that have made competing claims of entitlement to funds held by BNY. This action will resolve the parties’ respective entitlements to the funds, including a determination of whether an Event of Default have occurred under the COFINA resolution.
On May 2, 2017, the Oversight Board certified a ten-year fiscal plan (the “PRHTA Fiscal Plan”) for the Puerto Rico Highways and Transportation Authority (“PRHTA”). The PRHTA Fiscal Plan reflects an expectation that the Puerto Rico Treasury and PRHTA will temporarily cease funding debt service payments in July of 2017. The PRHTA Fiscal Plan states that as a result of the “clawback” of certain revenues pledged to PRHTA, PRHTA has insufficient cash flow to service debt. It is currently unclear when the funding of PRHTA debt service payments with pledged revenues will resume.
The Governor signed into law Act No. 1 of 2017, on January 11, 2017, which amended the Commonwealth’s Public-Private Partnership Act (Act No. 29 of 2009) ("P3 Act") authorizing the Public-Private Partnerships Authority (“P3A”) to facilitate privatization agreements between Partnering Government Entities (as such term is defined in the P3 Act) and private entities. The 2017 amendments allow the P3A to receive and consider unsolicited or voluntary proposals from proponents that meet the minimum criteria set forth in the P3 Act, whereas prior to the 2017 amendments, proposals could only be received in response to a P3A request for proposals. Direct negotiations with proponents of unsolicited or voluntary proposals may be conducted without a request for qualifications or a request for proposals process if the P3A determines that certain criteria have been met. The 2017 amendments also permit the use of the initial and/or periodical payments received from any partnership for contributions to the retirement systems of the Government of Puerto Rico, in addition to other uses provided for by the P3 Act, including the payment of debts of Partnering Government Entities. It is unclear how Puerto Rico will make use of the law and to what extent it will impact the obligations that we insure.
In response to letter requests from Governor Rosselló, the Oversight Board commenced a Title III proceeding for the Commonwealth of Puerto Rico on May 3, 2017 and for COFINA on May 5, 2017. Subsequently , the Oversight Board commenced a Title III proceeding for the Employees Retirement System and PRHTA on May 21, 2017, and for the Puerto Rico Electric Power Authority on July 2, 2017. Ambac Assurance has not issued any financial guaranty policies with respect to obligations of the Employees Retirement System or the Puerto Rico Electric Power Authority. As part of the Title III filings for the Commonwealth and COFINA, the Oversight Board noted that the Oversight Board and the Commonwealth intend to continue pursuing consensual negotiations under the protection of the Title III automatic stay.
On June 14, 2017, Judge Laura Taylor Swain entered an order appointing a team of mediators to facilitate confidential mediation discussions in order to facilitate consensual resolution of certain issues arising in the context of these Title III cases. The mediation team is led by Chief Judge Barbara Houser of the United States Bankruptcy Court for the Northern District of Texas, and consists of Circuit Judge Thomas Ambro of the United States Court of Appeals for the Third Circuit, Senior District Judge Nancy Atlas of the United States District Court for the Southern District of Texas, Bankruptcy Judge Christopher Klein of the United States Bankruptcy Court for the Eastern District of California, and Senior District Judge Victor Marrero of the United States District Court for the Southern District of New York. The mediators held an introductory mediation session, primarily for scheduling and housekeeping matters, on July 12, 2017. The mediators requested initial, confidential mediation statements identifying the issues to be discussed in the mediation(s) and the order in which the issues presented are to be taken up by July 24, 2017. The substantive mediation process is not expected to get underway until September. No assurances can be given that consensual resolutions will be achieved with respect to the Commonwealth’s or COFINA’s obligations or those of any other Puerto Rico instrumentality. In addition, Ambac is uncertain how the Title III process will be implemented and to what extent the rights of Ambac Assurance will be respected as part of that process.
On June 30, 2017, the Oversight Board certified the Commonwealth’s fiscal year 2018 budget, which is largely compliant with the FEGP. The budget does not allocate funds for debt service, stating only that it will do so after a Title III plan of adjustment or Title VI agreement is approved by the Court.
Ambac Assurance is party to nine litigations related to its Puerto Rico exposures. These include three litigations challenging the constitutionality and legality of the FEGP and the Fiscal Plan Compliance Act, discussed below under Note 11. Commitments and Contingencies , one of which is an adversary proceeding actively pending in PRHTA’s Title III proceedings . Ambac Assurance filed several of those cases to protect and assert its rights under transaction documents and applicable law. Six of these litigations are stayed under Title III of PROMESA, and one has been stayed by order of the United States District Court for the District of Puerto Rico pending resolution of an interpleader action related to COFINA funds (to which interpleader action Ambac is also a party). Accordingly, Ambac is unable to predict when and how the issues raised in those cases will be resolved. If Ambac Assurance is unsuccessful with any of these challenges, Ambac’s financial condition, including liquidity, loss reserves and capital resources may suffer a material negative impact.
Ambac has considered these developments and other factors in evaluating its Puerto Rico loss reserves. During the six months ended June 30, 2017 , Ambac had incurred losses associated with its Domestic Public Finance insured portfolio of $221,604 , which was significantly impacted by the continued uncertainty and volatility of the situation in Puerto Rico. While management believes its reserves are adequate to cover losses in its Public Finance insured portfolio, there can be no assurance that Ambac may not incur additional losses in the future, particularly given the developing economic, political, and legal circumstances in Puerto Rico. Such additional losses may have a material adverse effect on Ambac’s results of operations and financial condition. For public finance credits, including Puerto Rico, as well as other issuers, for which Ambac has

(Dollar Amounts in Thousands, Except Share Amounts)

an estimate of expected loss at June 30, 2017, the possible increase in loss reserves under stress or other adverse conditions and circumstances was estimated to be approximately $1.6 billion. However, there can be no assurance that losses may not exceed such amount.
2. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
The Company has disclosed its significant accounting policies in Note 2. Basis of Presentation and Significant Accounting Policies in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . The following significant accounting policies provide an update to those included in the Company’s Annual Report on Form 10-K.
Basis of Presentation
The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial reporting and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by GAAP for annual periods. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2016 . The accompanying consolidated financial statements have not been audited by an independent registered public accounting firm in accordance with the standards of the Public Company Accounting Oversight Board (U.S.), but in the opinion of management such financial statements include all adjustments necessary for the fair presentation of the Company’s consolidated financial position and results of operations. All intercompany balances and transactions have been eliminated. The results of operations for the three and six months ended June 30, 2017 may not be indicative of the results that may be expected for the year ending December 31, 2017 . The December 31, 2016 consolidated balance sheet was derived from audited financial statements.
The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. As additional information becomes available or actual amounts become determinable, the recorded estimates are revised and reflected in operating results.
Foreign Currency:
Financial statement accounts expressed in foreign currencies are translated into U.S. dollars in accordance with the Foreign Currency Matters Topic of the ASC. The functional currencies of Ambac's subsidiaries are the local currencies of the country where the respective subsidiaries are based, which are also the primary operating environments in which the subsidiaries operate.
Foreign currency translation : Functional currency assets and liabilities of Ambac’s foreign subsidiaries are translated into U.S. dollars using exchange rates in effect at the balance sheet dates and the related translation adjustments, net of deferred taxes, are included as a component of Accumulated Other Comprehensive Income in Stockholders' Equity. Consolidated Statements of Total Comprehensive Income (Loss) accounts expressed in functional currencies are translated using average exchange rates.
Foreign currency transactions : The impact of non-functional currency transactions and the remeasurement of non-functional currency assets and liabilities into the respective subsidiaries' functional currency (collectively "foreign currency transactions gains/(losses)") are $14,786 and $(29,150) for the six months ended June 30, 2017 and 2016 . Foreign currency transactions gains/(losses) are primarily the result of remeasuring Ambac UK's assets and liabilities denominated in currencies other than its functional currency, primarily the U.S. dollar and the Euro. The significant components of foreign currency transaction gains/(losses), including the respective classifications in the Consolidated Statement of Total Comprehensive Income, are as follows:
Remeasurement of loss reserves, classified in Loss and loss expenses, in the amount of $17,622 and $(48,260) for the six months ended June 30, 2017 and 2016 , respectively;
Realized gain (losses) from the sale of investment securities and the unrealized gains (losses) of trading and short-term investment securities, classified in Net realized investment gains, in the amount of $(432) and $13,632 for the six months ended June 30, 2017 and 2016 , respectively;
Remeasurement of premium receivables, classified in Other income, in the amount of $(981) and $6,945 for the six months ended June 30, 2017 and 2016 , respectively;
Remeasurement of cash held, classified in Other income, in the amount of $(503) and $(965) for the six months ended June 30, 2017 and 2016 , respectively and
Remeasurement of credit derivative liabilities, classified in Net change in fair value of credit derivative, in the amount of $(920) and $(502) for the six months ended June 30, 2017 and 2016 , respectively.
Reclassifications:
Certain reclassifications may have been made to prior years' amounts to conform to the current year's presentation.

Recently Adopted Accounting Standards:
Effective January 1, 2017, Ambac adopted the following accounting standards:
Consolidation of Variable Interest Entities - Decision Makers
In October 2016, the FASB issued ASU 2016-17, Consolidation (Topic 810) - Interests Held through Related Parties That Are under Common Control . The new guidance changes how a reporting entity that is a single decision maker for a VIE will consider its indirect interests in that VIE when determining whether the reporting entity is the primary beneficiary and should consolidate the VIE. Under previous GAAP, a single decision maker in a VIE is required to consider an indirect interest held by a related party under common control in its entirety. Under the new ASU, the single decision maker will consider the indirect interest on a proportionate basis. Adoption of this ASU did not have an impact on Ambac's financial statements.
Improvements to Employee Share-Based Payment Accounting
In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting . The objective of this ASU is to improve and simplify the accounting for employee share-based payment accounting. The amendments are as follows: (i) recognizing excess tax benefits and tax deficiencies as income tax expense, (ii) recognizing excess tax benefits regardless of whether it reduces taxes payable in the current period, (iii) classifying excess tax benefits related to share-based payments along with other income tax cash flows as an operating activity on the statement of cash flows, (iv) for purposes of accruing compensation costs, allowing companies to make an accounting policy election to either: a) estimate forfeitures or b) account for forfeitures as they occur, which Ambac elected to do upon adoption, (v) to qualify for equity classification treatment, permitting tax withholding by employees up to the maximum statutory tax rate and (vi) classifying cash paid by an employer to a taxing authority when directly withholding shares as a financing activity on the statement of cash flows. Adoption of this ASU did not have a material impact on Ambac's financial statements.
Equity Method of Accounting
In March 2016, the FASB issued ASU 2016-07, Investments-Equity Method and Joint Ventures (Topic 323) - Simplifying the Transition to the Equity Method of Accounting . This ASU eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively as if the equity method had been in effect during all previous periods that the investment had been owned. The ASU will now require that at the date an available-for-sale equity security becomes qualified for the equity method of accounting, the reporting entity will recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income. Adoption of this ASU did not have an impact on Ambac's financial statements.
Contingent Put and Call Options in Debt Instruments
In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815) - Contingent Put and Call Options in Debt Instruments . Previous accounting rules required that embedded derivatives be separated from the host contract in a financial instrument and accounted for separately as derivatives if certain criteria are met. One of these criteria is that the economic characteristics and risks of the embedded derivatives are not "clearly and closely related" to the host contract. The objective of the ASU is to resolve diversity in practice in assessing embedded contingent put and call options. The ASU clarifies what steps are required when assessing whether the economic characteristics and risk of put and call options are clearly and closely related to their debt host contracts. Adoption of this ASU did not have an impact on Ambac's financial statements.
Future Application of Accounting Standards:
Equity-linked instruments with down round features
In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260) and Derivatives and Hedging (Topic 815) - Accounting for Certain Financial Instruments with Down Round Features . Equity-linked instruments, such as warrants and convertible instruments may contain down round features that result in the strike price being reduced on the basis of the pricing of future equity offerings. Under the ASU, a down round feature will no longer require a freestanding equity-linked instrument (or embedded conversion option) to be classified as a liability that is remeasured at fair value through the income statement (i.e. marked-to-market). However, other features of the equity-linked instrument (or embedded conversion option) must still be evaluated to determine whether liability or equity classification is appropriate. Equity classified instruments are not marked-to-market. For earnings per share ("EPS") reporting, the ASU requires companies to recognize the effect of the down round feature only when it is triggered by treating it as a dividend and as a reduction of income available to common shareholders in basic EPS. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period. We have not determined whether Ambac will early adopt this ASU. The adoption of this ASU is not expected to have a material impact on Ambac's financial statements.
The ASU also contains accounting guidance on mandatorily redeemable financial instruments that is only applicable to nonpublic companies.

Stock Compensation--Scope of Modification Accounting
In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718) - Scope of Modification Accounting . The ASU provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. Entities will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. The current disclosure requirements in Topic 718 apply regardless of whether an entity is required to apply modification accounting under the amendments in this ASU. The amendments in this ASU are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Ambac will adopt this ASU on January 1, 2018. The adoption of this ASU is not expected to have a consequential impact on Ambac's financial statements.
Premium Amortization on Callable Debt Securities
In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities . The ASU shortens the amortization period for the premium on callable debt securities to the earliest call date. Under current GAAP, a reporting entity generally amortizes the premium as yield adjustment over the contractual life (i.e. maturity) of the debt security and if that debt security is called, the entity would record a loss equal to the unamortized premium. The ASU does not change the accounting for callable debt securities held at a discount, which will continue to be amortized to maturity. ASU 2017-08 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The ASU must be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We have not determined whether Ambac will early adopt this ASU and are evaluating the impact on Ambac's financial statements.
Net Periodic Pension and Postretirement Costs
In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . The objective of the ASU is to increase transparency in the reporting of net pension cost and net postretirement cost (collectively "net benefit cost"). The ASU requires that the service cost component of net benefit cost be reported on the same line item as other compensation costs arising from services rendered by employees. It further requires that the other components of net benefit costs (i.e. interest costs, amortization of prior service cost, etc.) be presented separately from the service cost component and outside the subtotal of income from operations, if one is presented. ASU 2017-09 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, with early adoption permitted. Ambac will adopt this ASU on January 1, 2018. The adoption of this ASU is not expected to have a consequential impact on Ambac's financial statements.

3. SPECIAL PURPOSE ENTITIES, INCLUDING VARIABLE INTEREST ENTITIES
Ambac, with its subsidiaries, has engaged in transactions with special purpose entities, including VIEs, in various capacities.
Ambac most commonly provides financial guarantees, including credit derivative contracts, for various debt obligations issued by special purpose entities, including VIEs ("FG VIEs").
Ambac sponsors special purpose entities that issued notes to fund the purchase of certain financial assets.
Ambac monetized its ownership of the junior surplus note issued to it by the Segregated Account by depositing the junior surplus note into a newly formed VIE trust in exchange for cash and an owner trust certificate, which represents Ambac's right to residual cash flows from the junior surplus note.
Ambac is an investor in collateralized debt obligations, mortgage-backed and other asset-backed securities issued by VIEs and its ownership interest is generally insignificant to the VIE and/or Ambac does not have rights that direct the activities that are most significant to such VIE.
FG VIEs:
Ambac’s subsidiaries provide financial guarantees in respect of assets held or debt obligations of special purpose entities, including VIEs. Ambac’s primary variable interest exists through this financial guarantee insurance or credit derivative contract. The transaction structures provide certain financial protection to Ambac. This financial protection can take several forms; however, the most common are over-collateralization, first loss and excess spread. In the case of over-collateralization (i.e., the principal amount of the securitized assets exceeds the principal amount of the debt obligations guaranteed), the structure allows the transaction to experience defaults among the securitized assets before a default is experienced on the debt obligations that have been guaranteed by Ambac’s subsidiaries. In the case of first loss, the financial guarantee insurance policy or credit derivative contract only covers a senior layer of losses on assets held or debt issued by special purpose entities, including VIEs. The first loss with respect to the assets is either retained by the asset seller or sold off in the form of equity or mezzanine debt to other investors. In the case of excess spread, the securitized assets contributed to special purpose entities, including VIEs, generate interest cash flows that are in excess of the interest payments on the related debt; such excess cash flow is applied to redeem debt, thus creating over-collateralization. Generally, upon deterioration in the performance of a transaction or upon an event of default as specified in the transaction legal documents, Ambac will


| Ambac Financial Group, Inc. 13 2017 Second Quarter FORM 10-Q |

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
Notes to Unaudited Consolidated Financial Statements
(Dollar Amounts in Thousands, Except Share Amounts)

obtain certain loss remediation rights. These rights may enable Ambac to direct the activities of the entity that most significantly impact the entity’s economic performance.
We determined that Ambac’s subsidiaries generally have the obligation to absorb a FG VIE's expected losses given that they have issued financial guarantees supporting the liabilities (and in certain cases assets). As further described below, we consolidated certain FG VIEs because: (i) we determined for certain transactions that experienced the aforementioned performance deterioration, that Ambac’s subsidiaries had the power, through voting rights or similar rights, to direct the activities that most significantly impact the VIE’s economic performance because certain triggers had been breached in these transactions resulting in Ambac's subsidiaries' ability to exercise certain loss remediation activities, or (ii) due to the passive nature of the VIEs’ activities, Ambac’s subsidiaries’ contingent loss remediation rights upon a breach of certain triggers in the future is considered to be the power to direct the activities that most significantly impact the VIEs’ economic performance. With respect to existing VIEs involving Ambac financial guarantees, Ambac is generally required to consolidate a VIE in the period that applicable triggers result in Ambac having control over the VIE’s most significant economic activities. In connection with the potential exit from Rehabilitation of the Segregated Account, as further described in Note 1. Background and Business Description , Ambac will need to evaluate consolidation of certain VIEs in the event certain rights are obtained by Ambac Assurance. Ambac has been informed by the OCI that they intend maintain certain control rights for policies that are currently allocated to the Segregated Account. Accordingly management expects the number of additional VIEs that may be consolidated as a result of the Segregated Account's potential exit from Rehabilitation will be reduced and possibly eliminated. A VIE is deconsolidated in the period that Ambac no longer has such control, which could occur in connection with the execution of remediation activities on the transaction or amortization of insured exposure, any of which may reduce the degree of Ambac’s control over a VIE. Assets and liabilities of FG VIEs that are consolidated are reported within Variable interest entity assets or Variable interest entity liabilities on the Consolidated Balance Sheets. The net results from such FG VIEs are reported within Income (loss) on variable interest entities in the Consolidated Statements of Total Comprehensive Income (Loss).
Upon initial consolidation of a FG VIE, we recognize a gain or loss in earnings for the difference between: (i) the fair value of the consideration paid, the fair value of any non-controlling interests and the reported amount of any previously held interests and (ii) the net amount, as measured on a fair value basis, of the assets and liabilities consolidated. Upon deconsolidation of a FG VIE, we recognize a gain or loss for the difference between: (i) the fair value of any consideration received, the fair value of any retained non-controlling investment in the VIE and the carrying amount of any non-controlling interest in the VIE and (ii) the carrying amount of the VIE’s assets and liabilities. Gains or losses from consolidation and deconsolidation that are reported in earnings are reported within Income (loss) on variable interest entities on the Consolidated Statements of Total Comprehensive Income (Loss).
The impact of consolidating such FG VIEs on Ambac’s balance sheet is the elimination of transactions between the consolidated FG VIEs and Ambac’s operating subsidiaries and the inclusion of the FG VIE’s third party assets and liabilities. For a financial guarantee insurance policy issued to a consolidated VIE, Ambac does not reflect the financial guarantee insurance policy in accordance with the related insurance accounting rules under the Financial Services – Insurance Topic of the ASC. Consequently, upon consolidation, Ambac eliminates the insurance assets and liabilities associated with the policy from the Consolidated Balance Sheets. Such insurance assets and liabilities may include premium receivables, reinsurance recoverable, deferred ceded premium, subrogation recoverable, unearned premiums, loss and loss expense reserves, ceded premiums payable and insurance intangible assets. For investment securities owned by Ambac that are debt instruments issued by the VIE, the investment securities balance is eliminated upon consolidation.
As of June 30, 2017 consolidated FG VIE assets and liabilities relating to 12 consolidated entities were $14,095,210 and $13,967,628 , respectively. As of December 31, 2016 , consolidated FG VIE assets and liabilities relating to 12 consolidated entities were $13,367,834 and $13,235,425 , respectively. As of both June 30, 2017 and December 31, 2016 , eight and four consolidated FG VIEs related to transactions insured by Ambac UK and Ambac Assurance, respectively. As of June 30, 2017 , FG VIE assets and liabilities of $13,700,687 and $13,583,319 and as of December 31, 2016 , FG VIE assets and liabilities of $12,950,009 and $12,833,466 related to transactions guaranteed by Ambac UK. The remaining balance of consolidated FG VIE assets and liabilities are related to transactions guaranteed by Ambac Assurance. Ambac is not primarily liable for, and generally does not guarantee all of the debt obligations issued by the VIEs. Ambac would only be required to make payments on the VIE debt obligations in the event that the issuer of such debt obligations defaults on any principal or interest due and such obligation is guaranteed by Ambac. Additionally, Ambac’s general creditors, other than those specific policy holders which own the VIE debt obligations, do not have rights with regard to the assets of the VIEs. Ambac evaluates the net income effects and earnings per share effects to determine attributions between Ambac and non-controlling interests as a result of consolidating a VIE. Ambac has determined that the net income and earnings per share effect of most consolidated FG VIEs are attributable to Ambac’s interests through financial guarantee premium and loss payments with the VIE.
Below is a schedule detailing the change in fair value of the various financial instruments within the consolidated FG VIEs, along with gains (losses) from consolidating and deconsolidating FG VIEs, that together comprise Income (loss) on variable interest entities for the affected periods:

Ambac Sponsored VIEs:
A subsidiary of Ambac transferred financial assets to a special purpose entity. The business purpose of this entity was to provide certain financial guarantee clients with funding for their debt obligations. This special purpose entity was established as a separate legal entity, demonstrably distinct from Ambac and that Ambac, its affiliates or its agents could not unilaterally dissolve. The permitted activities of this entity was contractually limited to purchasing assets from Ambac, issuing medium-term notes (“MTNs”) to fund such purchases, executing derivative hedges and obtaining financial guarantee policies with respect to indebtedness incurred. Ambac has not consolidated this entity because Ambac Assurance’s policies issued to this entity were allocated to the Segregated Account, thereby limiting Ambac’s control over the entity's most significant economic activities. Ambac has elected to account for its equity interest in this entity at fair value under the fair value option in accordance with the Financial Instruments Topic of the ASC. We believe that the fair value of the investments in this entity provides for greater transparency for recording profit or loss as compared to the equity method under the Investments – Equity Method and Joint Ventures Topic of the ASC. Refer to Note 7. Fair Value Measurements for further information on the valuation technique and inputs used to measure the fair value of Ambac’s equity interest in this entity. At June 30, 2017 and December 31, 2016 the fair value of this entity was $6,691 and $7,382 , respectively, and is reported within Other assets on the Consolidated Balance Sheets.
Total principal amount of debt outstanding was $409,830 and $388,950 at June 30, 2017 and December 31, 2016 , respectively. In each case, Ambac sold assets to this entity. The assets are composed of utility obligations with a weighted average rating of BBB+ at June 30, 2017 and weighted average life of 4.9 years . The purchase by this entity of financial assets was financed through the issuance of MTNs, which are cross-collateralized by the purchased assets. The MTNs have the same expected weighted average life as the purchased assets. Derivative contracts (interest rate swaps) are used within the entity for economic hedging purposes only. Derivative positions were established at the time MTNs were issued to purchase financial assets. As of June 30, 2017 Ambac Assurance had financial guarantee insurance policies issued for all assets, MTNs and derivative contracts owned and outstanding by the entity.
Insurance premiums paid to Ambac Assurance by this entity is earned in a manner consistent with other insurance policies, over the risk period. Additionally, any losses incurred on such insurance policies are included in Ambac’s Consolidated Statements of Total Comprehensive Income (Loss). Under the terms of an Administrative Agency Agreement, Ambac provides certain administrative duties, primarily collecting amounts due on the obligations and making interest payments on the MTNs.

In July 2015, Ambac Assurance entered into a secured borrowing transaction whereby it sold 17 Ambac insured residential mortgage-backed securities (the "Securities") and all rights associated therewith as of May 31, 2015, to a Delaware statutory trust (the "Trust") in exchange for an equity certificate in the Trust, all financial guarantee claim payments associated with the Securities and cash of $146,000 (prior to expenses associated with the transaction). Although the Securities were legally sold to the Trust, the Securities will remain in Invested assets on the Consolidated Balance Sheets. The Securities had par and fair value of $311,528 and $352,446 as of June 30, 2017 , respectively. Refer to Note 8. Investments for further discussion of the restrictions on the invested assets. At the same time, a second Delaware statutory trust (the "Issuer"), issued $146,000 of debt securities and used the proceeds, together with an equity certificate of the Issuer, to purchase from the Trust a certificate secured by and entitling the Issuer to all principal and interest payments (other than financial guarantee claim payments) on the Securities. Interest on the debt securities is payable monthly at an annual rate of one month LIBOR + 2.8% . Both the Trust and the Issuer are consolidated VIEs because Ambac Assurance was involved in their design and holds a significant amount of the beneficial interests issued by the VIEs or guaranteed the assets held by the VIEs. VIE debt outstanding to third parties under this secured borrowing transaction had a carrying value of $85,981 and $102,403 as of June 30, 2017 and December 31, 2016 , respectively, and is reported in Long-Term Debt on the Consolidated Balance Sheets.
Variable Interests in Non-Consolidated VIEs
On August 28, 2014, Ambac monetized its ownership of the junior surplus note issued to it by the Segregated Account by depositing the junior surplus note into a newly formed VIE trust in exchange for cash and an owner trust certificate, which represents Ambac's right to residual cash flows from the junior surplus note. Ambac does not consolidate the VIE. Ambac reports its interest in the VIE as an equity investment within Other investments on the Consolidated Balance Sheets with associated results from operations included within Net investment income: Other investments on the Consolidated Statements of Total Comprehensive Income (Loss). The equity investment had a carrying value of $32,418 and $30,003 as of June 30, 2017 and December 31, 2016 , respectively.
The following table displays the carrying amount of the assets, liabilities and maximum exposure to loss of Ambac’s variable interests in non-consolidated VIEs resulting from financial guarantee and derivative contracts by major underlying asset classes, as of June 30, 2017 and December 31, 2016 :

Basic net income per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding and vested restricted stock units. Diluted net income per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares used for basic earnings per share plus all potential dilutive common shares outstanding during the period. All potential dilutive common shares outstanding consider common stock deliverable pursuant to warrants issued under the Reorganization Plan, vested and unvested options, unvested restricted stock units and performance stock units granted under employee and director compensation plans.
The following table provides a reconciliation of the common shares used for basic net income per share to the diluted shares used for diluted net income per share:

6. FINANCIAL GUARANTEE INSURANCE CONTRACTS
Amounts presented in this Note relate only to Ambac’s non-derivative insurance business for insurance policies issued to beneficiaries, including VIEs, for which we do not consolidate the VIE.
Net Premiums Earned:
Gross premiums are received either upfront or in installments. For premiums received upfront, an unearned premium revenue (“UPR”) liability is established, which is initially recorded as the cash amount received. For installment premium transactions, a premium receivable asset and offsetting UPR liability is initially established in an amount equal to: (i) the present value of future contractual premiums due (the “contractual” method) or (ii) if the assets underlying the insured obligation are homogenous pools which are contractually prepayable, the present value of premiums to be collected over the expected life of the transaction (the “expected” method). An appropriate risk-free rate corresponding to the weighted average life of each policy and currency is used to discount the future premiums contractually due or expected to be collected. For example, U.S. dollar exposures are discounted using U.S. Treasury rates while exposures denominated in a foreign currency are discounted using the appropriate risk-free rate for the respective currency. The weighted average risk-free rate at June 30, 2017 and December 31, 2016 , was 2.5% and 2.6% , respectively, and the weighted average period of future premiums used to estimate the premium receivable at June 30, 2017 and December 31, 2016 , was 8.9 years and 9.0 years , respectively.
Insured obligations consisting of homogeneous pools for which Ambac uses expected future premiums to estimate the premium receivable and UPR include residential mortgage-backed securities. As prepayment assumptions change for homogenous pool transactions, or if there is an actual prepayment for a “contractual” method installment transaction, the related premium receivable and UPR are adjusted in equal and offsetting amounts with no immediate effect on earnings using new premium cash flows and the then current risk-free rate.
In structured finance transactions, the priority for the payment of financial guarantee premiums to Ambac, as required by bond indentures of insured structured finance obligations, is generally senior in the waterfall. Additionally, in connection with the allocation of certain liabilities to the Segregated Account, trustees and other parties are required under the Segregated Account Rehabilitation Plan and related court orders to continue to pay installment premiums, notwithstanding the Segregated Account Rehabilitation Proceedings. In evaluating the credit quality of the premium receivables, management evaluates the transaction waterfall structures and the internal ratings of the transactions underlying the premium receivables. Uncollectable premiums are determined on a policy basis and utilize a combination of historical premium collection data in addition to cash flow analysis to determine if an impairment in the related policy's premium receivables exist. As of June 30, 2017 and December 31, 2016 , approximately 22% and 25% of the premium receivables related to transactions with non-investment grade internal ratings, comprised mainly of non-investment grade RMBS, structured insurance, lease securitizations and student loan transactions, which comprised 7% , 5% , 3% and 3% , of the total premium receivables at June 30, 2017 and 8% , 5% , 4% and 3% of the total premium receivables at December 31, 2016 , respectively. At June 30, 2017 and December 31, 2016 , $9,337 and $9,186 respectively, of premium receivables were deemed uncollectable. Past due premiums on policies insuring non-investment grade obligations amounted to less than $500 at June 30, 2017 .
Below is the gross premium receivable roll-forward for the affected periods:

Gross premium receivable includes premiums to be received in foreign denominated currencies most notab ly in British Pounds and Euros. At June 30, 2017 and 2016 , premium receivables include British Pounds of $192,983 ( £148,277 ) and $206,834 ( £156,136 ), respectively, and Euros of $35,814 ( €31,361 ) and $37,741 ( €34,056 ), respectively.
Similar to gross premiums, premiums ceded to reinsurers are paid either upfront or in installments. Premiums ceded to reinsurers reduce the amount of premiums earned by Ambac from its financial guarantee insurance policies.
When a bond issue insured by Ambac Assurance has been retired early, typically due to an issuer call, any remaining UPR is recognized at that time to the extent the financial guarantee contract is legally extinguished, causing accelerated premium revenue. For installment premium paying transactions, we offset the recognition of any remaining UPR by the reduction of the related premium receivable to zero (as it will not be collected as a result of the retirement), which may cause negative accelerated premium revenue. Ambac’s accelerated premium revenue for retired obligations for the three and six months ended June 30, 2017 was $13,190 and $29,470 , respectively, and for the three and six months ended June 30, 2016 was $5,081 and $20,057 , respectively. Certain obligations insured by Ambac have been legally defeased whereby government securities are purchased by the issuer with the proceeds of a new bond issuance, or less frequently with other funds of the issuer, and held in escrow. The

(Dollar Amounts in Thousands, Except Share Amounts)

principal and interest received from the escrowed securities are then used to retire the Ambac-insured obligations at a future date either to their maturity date (a refunding) or a specified call date (a pre-refunding). Ambac has evaluated the provisions in policies issued on these obligations and determined those insurance policies have not been legally extinguished. For policies with refunding securities, premium revenue recognition is not impacted as the escrowed maturity date is the same as the previous legal maturity date. For policies with pre-refunding securities, the maturity date of the pre-refunded security has been shortened from its previous legal maturity. Although premium revenue recognition has not been accelerated in the period of the pre-refunding, it results in an increase in the rate at which the policy's remaining UPR is to be recognized.
The effect of reinsurance on premiums written and earned for the respective periods was as follows:
