While SPCP and MGA/U are distinct businesses, they are currently not significant to Ambac's operations to warrant segment presentation. Management reviews financial information, allocates resourcesevaluates its reportable segments at least annually and measures financial performance on a consolidated basis. As a result, the Company has a single reportable segment.as facts and circumstances change.
Strategies to Enhance Shareholder Value
The Company's primary goal is to maximize shareholder value through executing the following key strategies:
Active runoff of Ambac AssuranceAAC and its subsidiaries through transaction terminations, policy commutations, reinsurance, settlementsrestructurings, and restructurings,reinsurance with a focus on our watch list credits and known
and potential future adversely classified credits, that we believe will improve our risk profile, and maximizing the risk-adjusted return on invested assets;
Ongoing rationalization of Ambac's capital and liability structures;
Loss recovery through active litigation management and exercise of contractual and legal rights;
Ongoing review of the effectiveness and efficiency of Ambac's operating platform; and
EvaluationFocused growth in the specialty property and casualty program insurance, managing general agency/underwriting and potentially other insurance and insurance related businesses to advance our goal of opportunities in certain business sectors that meet acceptable criteria that will generategenerating long-term stockholder value with attractive risk-adjustedrisk adjusted returns.
With respect to our new business strategy, we continue to evaluate and pursue strategic opportunities in credit, insurance, asset management and other financial services that we believe would be synergistic to Ambac and would leverage our core competencies. While we have increased our efforts in evaluating such potential opportunities, we continue to be measured and disciplined in our approach as we seek to deploy our capital on opportunities that will
generate sustainable long-term shareholder value. Although we are exploring new business opportunities for AFG, no assurance can be given that we will be able to identify or execute a suitable transaction and/or obtain the financial and other resources that may be required to finance the acquisition or develop any new businesses or assets. As a consequence of the coronavirus disease 2019 ("COVID-19") pandemic, risks associated with our new businesses strategy have increased given uncertainties related to the resulting global recession, increase in business risk in our target sectors and disruption to the capital markets. 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 remains speculative.
The execution of AFG’sAmbac’s strategy to extract and increase the value of its investment in Ambac AssuranceAAC is subject to the restrictions set forth in the Settlement Agreement, dated as of June 7, 2010 (the "Settlement Agreement"), by and among Ambac Assurance,AAC, Ambac Credit Products LLC ("ACP"), AFG and certain counterparties to credit default swaps with ACP that were guaranteed by Ambac Assurance,AAC, as well as the Stipulation and Order and in the indenture for the Tier 2 Notes, each of which requiresamong the Office of the Commissioner of Insurance for the State of Wisconsin (“OCI”), AFG and AAC that became effective on February 12, 2018, as amended (the “Stipulation and Order”), and the indenture for the Tier 2 Notes (as defined below), each of which requires OCI and, under certain circumstances, holders of the debt instruments benefiting from such restrictions, to approve certain actions taken by or in respect of Ambac Assurance.AAC. In exercising its approval rights, OCI will act for the benefit of policyholders, and will not take into account the interests of AFG. AFG's strategy
2021 Surplus Note Exchanges
On January 19, 2021, AAC entered into a purchase agreement (the “Purchase Agreement”) with AFG and certain funds or accounts (the “Note Holders”), pursuant to extractwhich (i) the Note Holders agreed to sell to AAC all of the individual beneficial interests (the “Interests”) in the 5.1% senior notes due August 28, 2039 (the “Corolla Notes”), issued by the Corolla Trust, a Delaware statutory trust formed by AFG in 2014, (ii) AFG agreed to sell to AAC the owner trust certificate for the Corolla Trust (the “Corolla Certificate”), which constituted all of the equity interests in the Corolla Trust, and increase(iii) AAC agreed to exchange the valueInterests and the Corolla Certificate for AAC’s senior surplus notes (collectively, the “Corolla Note Exchange”).

Pursuant to the consequencesPurchase Agreement, each $1.00 principal amount of the COVID-19 pandemicCorolla Notes (and the associated amount of accrued and unpaid interest thereon) was exchanged for $0.9125 principal amount of senior surplus notes (and the associated amount of accrued and unpaid interest thereon) on the global economy, issuersdate of the consummation of the Corolla Note Exchange (the “Closing”). In addition, every $1.00 principal amount of the Corolla Certificate (and the associated amount of accrued and unpaid interest thereon) was exchanged for $0.6400 principal amount of senior surplus notes (and the associated amount of accrued and unpaid interest thereon) on the date of Closing. The Closing occurred on January 22, 2021. At the Closing AAC issued $267 aggregate principal amount of senior surplus notes to consummate the

Corolla Note Exchange and acquire all of the interests in the Corolla Trust. Subsequent to the closing the Corolla Trust was dissolved and the junior surplus note that had been deposited in the Corolla Trust by AFG in 2014 was canceled.
In February 2021, AAC entered into a purchase agreement pursuant to which the holder of $15 principal amount of 5.1% junior surplus notes issued by AAC agreed to sell such notes to AAC in exchange for senior surplus notes (the "JSN Exchange"). Pursuant to the purchase agreement, each $1.00 principal amount of the junior surplus notes (and the associated amount of accrued and unpaid interest thereon) was exchanged for $0.8581 principal amount of senior surplus notes (and the associated amount of accrued and unpaid interest thereon). The closing of the JSN Exchange occurred on February 11, 2021, when AAC issued approximately $13 aggregate principal amount of senior surplus notes. Subsequent to the closing of the JSN Exchange the junior surplus notes were canceled. As a result of the Corolla Note Exchange and the JSN Exchange, AAC no longer has any junior surplus notes outstanding.
The surplus notes exchanged pursuant to the Corolla Note Exchange and the JSN Exchange are part of the same series as, and rank equally with, the existing surplus notes previously issued by AAC. After giving effect to the Corolla Note Exchange and the JSN Exchange, AAC has $853 principal amount of surplus notes outstanding and total principal and accrued and unpaid interest of surplus notes outstanding is $1,414 as of February 11, 2021. Outstanding surplus notes principal amount includes $83 owned by AFG, which amount is eliminated in consolidation for purposes of US generally accepted accounting principles. The Company recorded a gain of $33 for the three months ended March 31, 2021 arising from AAC's purchases of junior surplus notes below their carrying values which is reported within Net realized gains (losses) on extinguishment of debt insured by Ambac, and issuersin the Consolidated Statements of debt and other investments owned by Ambac.

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, 2019.2020. The following significant accounting policies provide an update to those included in the Company’s Annual Report on Form 10-K.
Consolidation:
The consolidated financial statements include the accounts of AFG and all other entities in which AFG (directly or through its subsidiaries) has a controlling financial interest, including variable


| Ambac Financial Group, Inc. 52020 First Quarter FORM 10-Q |

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

interest entities (“VIEs”) for which AFG or an AFG subsidiary is deemed the primary beneficiary in accordance with the Consolidation Topic of the Accounting Standards Codification ("ASC"). All significant intercompany balances have been eliminated. The usual condition for a controlling financial interest is ownership of a majority of the voting interests of an entity. However, a controlling financial interest may also exist in entities, such as VIEs, through arrangements that do not involve controlling voting interests. A VIE is an entity: a) that lacks enough equity investment at risk to permit the entity to finance its activities without additional subordinated financial support from other parties; or b) where the group of equity holders does not have: (1) the power, through voting rights or similar rights, to direct the activities of an entity that most significantly impact the entity’s economic performance; (2) the obligation to absorb the entity’s expected losses; or (3) the right to receive the entity’s expected residual returns. The determination of whether a variable interest holder is the primary beneficiary involves performing a qualitative analysis of the VIE that includes, among other factors, its capital structure, contractual terms including the rights of each variable interest holder, the activities of the VIE, whether the variable interest holder has the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, whether the variable interest holder has the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, related party relationships and the design of the VIE. An entity that is deemed the primary beneficiary of a VIE is required to consolidate the VIE. See Note 3. Variable Interest Entities, for a
detailed discussion of Ambac’s involvement in VIEs, Ambac’s methodology for determining whether Ambac is required to consolidate a VIE and the effects of VIEs being consolidated and deconsolidated.
Basis of PresentationPresentation:
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 consolidated 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, 2019.2020. 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. The results of operations for the three months ended March 31, 20202021, may not be indicative of the results that may be expected for the year ending December 31, 2020.2021. The December 31, 20192020, 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 AFG'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 AFG’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. Functional currency operating results of foreign subsidiaries 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 $1$(5) and $2$1 for the three months ended March 31, 20202021 and 2019,2020, respectively. 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.
Revenue Recognition:
Revenues for the MGA/U business operations are recognized in accordance with the Revenue from Contracts with Customers Topic of the ASC. The following steps are applied to recognize revenue: identify the contract(s) with the customer, identify the performance obligations in the contract(s), determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when (or as) the entity satisfies a performance obligation. A performance obligation is satisfied either at a point in time or over time depending on the nature of the product or service provided, and the specific terms of the contract with customers.

(Dollar Amounts in Millions, Except Share Amounts)

MGA/U performance obligations consist of placing policies with insurers and, for certain products, providing claims servicing. Revenue from limited and short-term medical policies sold through affinity groups ("Affinity") are recognized up front as no further performance obligations exist after policy placement. Revenue from employer stop loss policies ("ESL") is apportioned to policy placement, recognized upfront, and claims servicing, recognized over the claim period, based on the relative stand-alone selling price of the respective performance obligations.
Revenue consists of base and profit-sharing commissions. Base commissions, associated with policy placement and claims servicing, are estimated by applying the contractual commission percentages to estimated gross premiums written. Profit-sharing commissions represent variable consideration associated with policy placement only and are estimated based on expected loss ratios and the estimated gross premium for base commissions. Base and profit-sharing commissions are estimated with a constraint applied such that a significant reversal of revenue in the future is not probable. MGA/U revenue is reported in other income (expense) on the Consolidated Statement of Total Comprehensive Income.
Contract assets represent the Company's right to future consideration for services it has already transferred to the customer, which is also conditional on future performance. Once the right to consideration becomes unconditional, it is reported as a receivable. Contract liabilities represent the Company's obligation to transfer services for which it has already received consideration from the customer. Contract assets and contract liabilities are reported as other assets and other liabilities, respectively, on the Consolidated Balance Sheet.

in the Notes to Consolidated Financial Statements included in Part II, Item 8 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. Under the terms of the acquisition agreement, Ambac received a call option to purchase the remaining 20% of Xchange from the minority owners (i.e., noncontrolling interests) and the minority owners received a put option to sell the remaining 20% to Ambac. The call and put options are exercisable after different time periods elapse. Because the exercise of the put option is outside the control of Ambac, in accordance with the Distinguishing Liabilities from Equity Topic of the ASC, Ambac reports redeemable noncontrolling interests in the mezzanine section of its consolidated balance sheet.
The redeemable noncontrolling interest is remeasured each period as the greater of:
i.the carrying value under ASC 810, which attributes a portion of consolidated net income (loss) to the redeemable noncontrolling interest; and
ii.the redemption value of the put option under ASC 480 as if it were exercisable at the end of the reporting period.
Any increase (decrease) in the carrying amount of the redeemable noncontrolling interest as a result of adjusting to the redemption value of the put option is recorded as an offset to retained earnings. The impact of such differences on earnings per share are presented in Note 5. Net Income Per Share.

Reclassifications and Rounding
Reclassifications may have been made to prior years' amounts to conform to the current year's presentation. Certain amounts and
tables in the consolidated financial statements and associated notes may not add due to rounding.
Adopted Accounting Standards:
Effective January 1, 2020, the Company adopted the following accounting standards:
Measurement of Credit Losses on Financial Instruments (CECL)
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments, subsequently amended by ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses; ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments; ASU 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief; and ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments - Credit Losses (collectively the Current Expected Credit Loss standard or "CECL")
The new CECL standard affects how reporting entities measure credit losses for financial assets that are not accounted for at fair value through net income. For Ambac, these financial assets include available-for-sale debt securities, premium receivables, reinsurance recoverables, and loans. CECL does not apply to recoveries of previously paid losses on financial guarantee insurance contracts accounted for under ASC 944 nor does it apply to equity method investments accounted for under ASC 323.
For available-for-sale debt securities, the updated guidance was applied prospectively and for financial instruments measured at amortized cost, the updated guidance was applied by a cumulative effect adjustment to the opening balance of retained earnings at January 1, 2020. This adjustment was not material to retained earnings or any individual balance sheet line item.
As a result of adopting CECL, management revised its policies and procedures around the credit impairment evaluation process. CECL also introduced new disclosures related to the credit impairment process, including certain accounting policy elections that Ambac made under the the new standard. Enhanced disclosures related to accounting policies for each type of asset impacted by CECL are discussed below. The disclosures below should be read in conjunction with disclosures in Note 2. Basis of Presentation and Significant Accounting Policies, Note 6. Financial Guarantee Insurance Contracts and Note 8. Investments in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.
Available-for-Sale Securities
For available-for-sale debt securities, credit losses under CECL are measured similarly to other-than-temporary impairments under prior GAAP. However, under CECL, the recognition of credit losses for available-for-sale debt securities will be recorded as an allowance for credit losses with an offsetting charge to net income, rather than as a direct write-down of the security as was required under prior GAAP. As a result, improvements to estimated credit losses for available-for-sale debt securities will be recognized immediately in net income rather than as interest income over time. Furthermore, as required under CECL, Ambac no longer considers the length of time a security has continuously been in an unrealized loss in the credit impairment process.
Ambac has made certain accounting policy elections related to accrued interest receivable ("AIR") for available-for-sale investments under CECL, which are consistent with past practices under prior GAAP. Elections include: i) not measuring AIR for credit impairment, instead AIR is written off when it becomes 90 days past due; ii) writing off AIR by reversing interest income; iii) presenting AIR separately in Other Assets on the balance sheet and iv) excluding AIR from amortized cost balances in required CECL disclosures found in Note 8. Investments. AIR at March 31, 2020 was $12.
Refer to Note 8. Investments for further credit impairment disclosures.

Adopted Accounting Standards:
Amortized cost assetsEffective January 1, 2021, the Company adopted the following accounting standard:
For financial assets measured at amortized cost, CECL replaces the "incurred loss" model used for certain types of assets which generally delayed recognition of the full amount of credit losses until the loss was probable of occurring, with an "expected loss" model, which reflects an entity's current estimate of all expected lifetime credit losses. The estimate of expected lifetime credit losses should consider historical information, current information, as well as reasonable and supportable forecasts. Expected lifetime credit losses for amortized cost assets will be recorded as an allowance for credit losses, with subsequent increases or decreases in the allowance reflected in net income each period. The CECL measurement approach for Ambac's affected asset types were not materially different than the approaches under prior GAAP. Refer to the discussion below for each asset type.
Premium receivables.For financial guarantee contracts, the receipt of premiums and payment of policy losses are both dependent on the issuer of the insured obligation's ability and willingness to pay. As such, management leverages its existing loss reserve estimation process to evaluate credit impairment for premium receivables. Key factors in assessing credit impairment include historical premium collection data, internal risk classifications, credit ratings and loss severities. For structured finance transactions involving special purpose entities, we further evaluate the priority of premiums paid to Ambac within the contractual waterfall, as required by bond indentures.
Management utilizes either a discounted cash flow ("DCF") or probability of default/loss given default ("PD/LGD") approach to estimate credit impairment. The DCF approach utilizes expected cash flows developed by Ambac's Risk Management Group using the same (or similar) models used for estimating loss reserves where such models can identify shortfalls in premiums. Credit impairment using the DCF approach is equal to the difference between amortized cost and the present value of expected cash flows. Credit impairment under the PD/LGD approach is the product of (i) the premium receivable carrying value, (ii) internally developed default probability (considering internal ratings and average life), and (iii) internally developed loss severities.
Refer to Note 6. Financial Guarantee Insurance Contracts for further credit impairment disclosures.
Loans. The key factors in assessing credit impairment for loans are internal credit ratings and loss severities. Management utilizes a PD/LGD approach, similar to the one described above for premium receivables, which is applied to the loan carrying value.
Reinsurance recoverables. Ambac has elected the to use the practical expedient of considering the fair value of collateral posted by reinsurers when evaluating credit impairment. To determine the total unsecured recoverable to be evaluated for impairment, Ambac nets the reinsurance recoverable amount by ceded premiums payable and the fair value of collateral posted, if any.
The key factors in assessing credit impairment for reinsurance recoverables are independent rating agency credit ratings and loss severities. Management utilizes a PD/LGD approach, similar to the one described above for premium receivables, which is applied to the net unsecured reinsurance recoverable amount.
Refer to Note 6. Financial Guarantee Insurance Contracts for further credit impairment disclosures.
Fair Value Measurement DisclosuresSimplifying Income Tax Accounting
In August 2018,December 2019, the FASB issued ASU 2018-13,2019-12, Fair Value MeasurementIncome Taxes (Topic 820)740) - Disclosure Framework - Changes toSimplifying the Disclosure RequirementsAccounting for Fair Value MeasurementIncome Taxes. The FASB issued this ASU modified various disclosure requirements on fair value measurements. Relevant disclosures that were removed, modified and added are as follows:
Removals: 1) Amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, 2) Policy for timing of transfers between levels, and 3) Valuation processes for Level 3 fair value measurements.
Modifications: 1) For investments in certain entities that calculate net asset value, disclosures are required for the timing of liquidation of an investee's assets and the date when restrictions from redemption might lapse, only if the investee has communicated the timing to the reporting entity or publicly announced it and 2) Clarification that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date and not possible future changes.
Additions: 1) Changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and 2) Range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. Alternatively, an entity may disclose other quantitative information (such as the median or arithmetic average) if it determines that it is a more reasonable and rational method to reflect the distribution of unobservable inputs used.
Disclosure amendmentspart of its initiative to reduce complexity in accounting standards. The ASU removes certain exceptions in the guidance related to changes in unrealized gainsinvestments, intra-period allocations and losses included in other comprehensive income (loss) for Level 3 instruments, the range and weighted average of significant unobservable inputs, and the narrative description of measurement uncertainty were applied prospectively only for the most recent interim or annual period presented. All other disclosure amendments were applied retrospectively to all periods presented.
Refer to Note 7. Fair Value Measurements forallocations. It further disclosures.
VIE Related Party Guidance
In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810) - Targeted Improvements to Related Party Guidance for Variable Interest Entities. To determine whether a decision-making fee is a variable interest, under theadds new guidance related to the allocation of consolidated income taxes and evaluating a reporting entity must consider indirect interests held through related parties under common control on a proportionalstep-up in the tax basis rather than as a direct interest in its entirety (as was previously required under prior GAAP). These amendments create alignment between determining whether a decision making fee is a variable interest and determining whether a reporting entity within a related party group is the primary beneficiary of a VIE. Adoption of thisgoodwill. The ASU did not have a consequential impact Ambac's financial statements.

Cloud Computing Arrangement Service Contracts
In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The new guidance requires a customer in a cloud computing arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. The internal-use software guidance requires the capitalization of certain costs incurred only during the application development stage. That guidance also requires entities to expense costs during the preliminary project and post-implementation stages as they are incurred. Adoption of this ASU did not impacton Ambac's financial statements.
Future Application of Accounting Standards:
Reference Rate Reform
In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The ASU provides companies with optional guidance to ease the potential accounting burden related to transitioning away from reference rates, such as LIBOR, that are expected to be discontinued as a result of initiatives undertaken by various jurisdictions around the world. For example, under current GAAP, contract modifications which change a reference rate are required to be evaluated in determining whether the modifications result in the establishment of new contracts or the continuation of existing contracts. The amendments in this ASU provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The ASU can be applied prospectively as of the beginning of the interim period that includes or is subsequent to March 12, 2020, (January 1, 2020 for calendar year companies) or any date thereafter, but does not apply to contract modifications and other transactions entered into or evaluated after December 31, 2022. Management has not determined if and when it will adopt this ASU, and the impact on Ambac's financial statements is being evaluated.
3. VARIABLE INTEREST ENTITIES
Ambac, with its subsidiaries, has engaged in transactions with variable interest entities ("VIEs,") in various capacities.
Ambac 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 investors for various purposes; and
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 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. Generally, upon deterioration in the performance of a transaction or upon an event of default as specified in the transaction legal documents, Ambac will obtain certain control rights that enable Ambac to remediate losses. These rights may enable Ambac to direct the activities of the entity that most significantly impact the entity’s economic performance. Under athe 2018 Stipulation and Order, the OCI requires Ambac AssuranceAAC is required to obtain theirOCI approval with respect to the exercise of certain significant control rights in connection with policies that had previously been allocated to the Segregated Account. Accordingly, Ambac AssuranceAAC does not have the right to direct the most significant activities of those FG VIEs.
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 certain liabilities (and in some cases certain assets). As further described below, Ambac consolidates certain FG VIEs in cases where we also have the power to direct the activities that most significantly impact the VIE’s economic performance due to one or more of the following: (i) the transaction experiencing deterioration and breaching performance triggers, giving Ambac the ability to exercise certain control rights, (ii) Ambac being involved in the design of the VIE and receiving control rights from its inception, such as may occur from loss remediation activities, or (iii) the transaction not experiencing deterioration, however due to the passive nature of the VIE, Ambac's contingent control rights upon a future breach of performance triggers is considered to be the power over the most significant activity.
A VIE is deconsolidated in the period that Ambac no longer has such control rights, which could occur in connection with the execution of remediation activities on the transaction or amortization of insured exposure, either 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 election to use the fair value option is made on an instrument by instrument basis. Ambac has elected the fair value option for consolidated FG VIE financial assets and financial liabilities, except in cases where Ambac was involved in the design of the VIE and was granted control rights at its inception.
When the fair value option is elected, changes in the fair value of the FG VIE's financial assets and liabilities are reported within Income (loss) on variable interest entities in the Consolidated Statements of Total Comprehensive Income (Loss), except for the portion of the total change in fair value of financial liabilities caused by changes in the instrument-specific credit risk which is presented separately in Other comprehensive income (loss).
In cases where the fair value option has not been elected, the FG VIE's invested assets are fixed income securities and are considered available-for-sale as defined by the Investments - Debt Securities Topic of the ASC. These assets are reported in the financial statements at fair value with unrealized gains and losses reflected in Accumulated Other Comprehensive Income in Stockholders' Equity.

with unrealized gains and losses reflected in Accumulated Other Comprehensive Income (Loss) in Stockholders' Equity. The financial liabilities of these FG VIEs consist of long term debt obligations and are carried at par less unamortized discount. Income from the FG VIE's available-for-sale securities (including investment income, realized gains and losses and credit impairments as applicable) and interest expense on long term debt 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, Ambac recognizes 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 recognizeAmbac recognizes 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 associated debt and investment securities balance isbalances are eliminated upon consolidation.
FG VIEs which are consolidated may include non-recourse assets or liabilities. FG VIEs' liabilities (and in some cases assets) that are insured by the Company are with recourse, because the Company guarantees the payment of principal and interest in the event the issuer defaults. FG VIEs' assets and liabilities that are not insured by the Company are without recourse, because Ambac has not issued a financial guarantee and is under no obligation for the payment of principal and interest of these instruments. Therefore, the Company’s economic exposure to consolidated FG VIEs is limited to the financial guarantees issued for recourse assets and liabilities and any additional variable interests held 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 consolidated FG VIEs are attributable to Ambac’s interests through financial guarantee premium and loss payments with the VIE.

Ambac Sponsored Non-consolidated VIEs:
In 1994, Ambac established a VIE to provide certain financial guarantee clients with funding for their debt obligations. This VIE 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 are 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 does not consolidate this entity because the exercise of related control rights in such policies remain subject to OCI approval under the Stipulation and Order, as discussed above. Ambac 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.

At March 31, 20202021 and December 31, 20192020, the fair value of this entity was $3$1 and $3,$1, respectively, and is reported within Other assets on the Consolidated Balance Sheets.
Total principal amount of debt outstanding was $378 and $403$410 at March 31, 2020 and December 31, 2019, respectively. In each case, Ambac sold assets to this entity, which are composed of utility obligations with a weighted average rating of BBB+ at March 31, 2020 and weighted average life of 0.9 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 March 31, 2020 Ambac Assurance had financial guarantee

Common shares outstanding increased by 223,623387,963 during the three months ended March 31, 2020,2021, primarily due to settlements of employee restricted and performance stock units.
BasicThe numerator of the basic and diluted earnings per share computation represents net income per share(loss) attributable to common stockholders adjusted by the retained earnings impact of the noncontrolling adjustment to redemption value under ASC 480. The redemption value adjustment is computed by dividingfurther described Redeemable Noncontrolling Interest section of Note 2. Basis of Presentation and Significant Accounting Policies,

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. The weighted average risk-free rate at March 31, 20202021 and December 31, 2019,2020, was 2.2% and 2.4%2.2%, respectively, and the weighted average period of future premiums used to estimate the premium receivable at March 31, 20202021 and December 31, 2019,2020, was 8.78.3 years and 8.58.3 years years, respectively.

(1)Adjustments for changes in expected and contractual cash flows primarily due to changes in indexation rates on certain UK transactions partially offset by reductions in insured exposure as a result of early policy terminations and unscheduled principal paydowns.
(2)Premium receivable includes premiums to be received in foreign denominated currencies most notably in British Pounds and Euros. At March 31, 2020 and 2019, premium receivables include British Pounds of $128 (£103) and $142 (£109), respectively, and Euros of $24 (€22) and $30 (€27), respectively.
When a bond issue insured by Ambac AssuranceAAC 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 months ended March 31, 20202021 and 20192020, was less than a million dollars and $12, respectively.in both periods.

Credit impairment (Premium receivables and reinsurance recoverables):Impairment for Premium Receivables:
Management evaluates premium receivables and reinsurance recoverables for expected credit losses ("credit impairment") in accordance with the new CECL standard adopted January 1, 2020, which is further described in Note 2. Basis of Presentation and Significant Accounting Policies. in the Notes to Consolidated Financial Statements included in Ambac's Annual Report on Form 10-K for the year ended December 31, 2020. Management's evaluation of credit impairment under prior GAAP rules was not materially different.
Most credit impairment disclosures below were only made prospectively from the CECL adoption date as they were not required under prior GAAP rules.

As further discussed in Note 2. Basis of Presentation and Significant Accounting Policies, in the Notes to Consolidated Financial Statements included in Ambac's Annual Report on Form 10-K for the year ended December 31, 2020, the key indicator management uses to assess the credit quality of premium receivables is Ambac's internal risk classifications for the insured obligation determined by the Risk Management Group.

For 2021, the adverse development in prior years was primarily due to deterioration of Puerto Rico credits as discussed below in the section, "Puerto Rico."
For 2020, the adverse development in prior years was primarily a result of deterioration in Public Finance credits, primarily Puerto Rico, partially offset by positive development in the RMBS portfolio.
For 2019, the adverse development in prior years was primarily a result of deterioration in Public Finance credits, partially offset by positive development in the RMBS and Ambac UK portfolios.

COVID-19:
In March 2020, the outbreak of COVID-19 relatedpandemic, caused by a novel strain of the coronavirus, was recognized as a pandemic by the World Health Organization, and the outbreak is widespread globally, including in the markets in which we operate. The COVID-19 outbreak had, and continues to have, a notable impact on general economic disruptionconditions, including but not limited to higher unemployment; volatility in the capital markets; closure or severe curtailment of the operations and, hence, revenues, of many businesses and public and private enterprises to which we are directly or indirectly exposed, such as hotels, restaurants, sports and entertainment facilities, airports and other transportation facilities, and retail establishments, mostly due to social distancing guidelines, travel bans and restrictions, and business restrictions and shutdowns.
COVID-19 has adversely impacted Ambac's financial position and results of operations as credit risk in the insured and
investment portfolios has increased. In the insured portfolio, municipal, mortgage-backed, student loan and other asset securitization exposures could be materially adversely impacted.
In the U.S., significant fiscal stimulus measures, monetary policy actions and other relief measures have helped to moderate the negative economic impacts of COVID-19, and have supported the economic recovery which began in the second half of 2020 and continues into 2021. These measures include the March 2021, $1.9 trillion American Rescue Plan Act or ARPA, which together with other fiscal stimulus measures put in place in 2020, provide for, among other things, funding to state and local governments, direct payments to households, support for small businesses, renter assistance and funding for transport, airlines, healthcare and education. Monetary policy decisions have included quantitative easing and the provision of liquidity to financial institutions and credit markets. In addition, housing measures, such as forbearance on marketsmortgages and suspension of foreclosures and evictions, and various executive orders have helped to

Puerto Rico:
Ambac has exposure to the Commonwealth of Puerto Rico (the "Commonwealth") and its instrumentalities across several different
issuing entities with total net par exposure of $1,105.$1,067. Components of Puerto Rico net par outstanding include capital appreciation bonds which are reported at the par amount at the time of issuance of the related insurance policy as opposed to the current accreted value of the bonds. Each issuing entity has its own credit risk profile attributable to discrete revenue sources, direct general obligation pledges or general obligation guarantees. The Commonwealth of Puerto Rico and certain of its instrumentalities have defaulted and may continue to default on debt service payments, including payments owed on bonds insured by Ambac Assurance. Ambac AssuranceAAC. AAC may be required to make significant amounts of policy payments over the next several years, the recoverability of which is subject to great uncertainty, which may lead to a material increase in permanent losses causing a material adverse impact on our results of operations and financial condition. Our exposure to Puerto Rico is impacted by the amount of monies available for debt service, which is in turn affected by a number of factors including variability in economic growth and demographic trends, economic conditions (includingtax revenues, changes in law or the impact

In the near term,near-term, the financial and economic outlook for Puerto Rico is dependent upon a still fragile infrastructure, heightening its vulnerability to additional natural disasters.weather events; and the trajectory of recovery from the COVID-19 pandemic. The longer termlonger-term recovery of the Commonwealth economy and its essential infrastructure will likely be dependent on, among other factors, the management, usage and efficacy of federal resources.
ItAlso important to Puerto Rico's economic growth, government reform and creditor outcomes is the Commonwealth Fiscal Plan, the most recent of which was certified by the Financial Oversight and Management Board for Puerto Rico ("Oversight Board") on April 23, 2021. The most recent Commonwealth Fiscal Plan purports to incorporate the impact of the federal recovery money stemming from the 2017 hurricanes, 2019-2020 earthquakes, and the COVID-19 pandemic, including the recently enacted ARPA. As with previous fiscal plans, the current certified Commonwealth Fiscal Plan may significantly inform the Commonwealth Plan of Adjustment in the Commonwealth's Title III proceeding. However, as was the case with previous versions of the Commonwealth Fiscal Plan, the current version of the
Commonwealth Fiscal Plan lacks a high degree of transparency regarding the underlying data, assumptions and rationales supporting those assumptions, making reconciliation and due diligence difficult. As a result, it is difficult to predict the long-term capacity and willingness of the Puerto Rico government and its instrumentalities to pay debt service on bonded debt and how their debt burden and financial flexibility might affect Ambac Assurance's claimAAC's claims development potential, risk profile and long-term financial strength.
In the first quarter of 2021, the Oversight Board, as representative of the Commonwealth of Puerto Rico, PBA, and the Employee Retirement System of the Government of the Commonwealth of Puerto Rico publicly disclosed the Second Amended Plan Support Agreement ("Second Amended PSA"). The Oversight Board announced that the Second Amended PSA had the support of 70% of all GO and PBA bonds claims, including the conditional support of several financial guarantee insurance companies. The Government of the Commonwealth of Puerto Rico and AAC are not currently parties to the Second Amended PSA. Later in the first quarter of 2021, the Oversight Board filed with the Title III court a Second Amended Title III Joint Plan of Adjustment of the Commonwealth ("Second Amended POA") that, among other things, incorporated the terms of the Second Amended PSA.
In April 2021, the Oversight Board announced that it had reached an agreement in principle with two financial guarantee insurance companies (not including AAC) regarding the Puerto Rico Highways and Transportation Authority ("PRHTA") claims, the Convention Center District Authority ("CCDA") claims and the Commonwealth treatment of deficiency claims. Under this agreement in principle, consideration for revenue bond creditors such as PRHTA, CCDA, or Puerto Rico Infrastructure Financing Authority ("PRIFA") Special Tax Revenue ("Rum Tax") bonds, on account of their deficiency claims ("Clawback claims") against the Commonwealth, consist of interests ("Clawback CVI") tied to the outperformance of the Puerto Rico Sales and Use Tax ("SUT") against the certified 2020 Commonwealth Fiscal Plan projections. Under the agreement, the PRHTA and CCDA creditors would also receive 'hard currency' in the form of new PRHTA bonds and cash for PRHTA creditors and cash for CCDA creditors. PRIFA is not part of this agreement and under the current construct, PRIFA bondholders would not receive any 'hard currency' and only receive the Clawback CVI. This agreement was finalized on May 5, 2021 (the "PRHTA/CCDA PSA").
Substantial uncertainty exists with respect to the ultimate outcome for creditors in Puerto Rico, such as Ambac Assurance,AAC, due to, amongstamong other matters, the Second Amended PSA and Second Amended POA and potential incremental changes to both the PSA and POA; the PRHTA/CCDA PSA; legislation enacted by the Commonwealth and the federal government, including PROMESA; and actions taken pursuant to such laws, including the Title III filings; the economic consequences of the COVID-19 pandemic; as well as political uncertainty and leadership turnover. Ambac Assurancefilings. AAC is involved in multiple litigations relating to such actions taken by the Commonwealth or the Financial Oversight and Management Board for Puerto Rico (the “Oversight Board”) pursuant to certain enacted legislation, court rulings, and other issues and may not be successful in pursuing claims or protecting its interests. As a result of litigation or other aspects of the restructuring processes, the differences among the credits insured by Ambac AssuranceAAC may not be respected.

not be productive or may not resolve Ambac Assurance'sAAC's claims in a manner that reduces or avoids significant losses. No assurances can be given that negotiations will be successfully concluded, that Commonwealth, Oversight Board and creditor parties will reach definitive agreements on additional debt restructurings, that any additional negotiated transaction debt restructuring, definitive agreement or Plansplans of Adjustmentadjustment will be approved by the court and completed, or that any transaction or Plansplans of Adjustmentadjustment will not have a materialan adverse impact on Ambac's financial condition or results of operations.results. It is possible that certain restructuring process solutions, together with associated legislation, budgetary, and/or public policy proposals could be adopted and could further impair our exposures, causing losses that could have a material adverse impact on our results of operations and financial condition.
While our reserving scenarios account for a wide range of possible outcomes, reflecting the significant uncertainty regarding future developments and outcomes, given our exposure to Puerto Rico and the economic, fiscal, legal and political uncertainties associated therewith as well as the uncertainties emanating from the COVID-19 pandemic and the damage caused by hurricanes Maria and Irma, our loss reserves may ultimately prove to be insufficient to cover our losses, potentially having a material adverse effect on our results of operations and financial position.position, and may be subject to material volatility.
Ambac has considered these developments and other factors in evaluating its Puerto Rico loss reserves. During the three months ended March 31, 2020,2021, Ambac had incurred losses associated with its Domestic Public Finance insured portfolio of $178,$9, which was primarily impacted by lower discount rates andour interpretation of the terms of the May 5, 2021 PRHTA/CCDA PSA, including our assessment of the Clawback CVI, as well as 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, given the circumstances described herein. Such additional losses may have a material adverse effect on Ambac’s results of operations and financial condition and may result in adverse consequences such as impairing the ability of Ambac AssuranceAAC to honor its financial obligations; the initiation of rehabilitation proceedings against Ambac Assurance;AAC; decreased likelihood of Ambac AssuranceAAC delivering value to Ambac, through dividends or otherwise; and a significant drop in the value of securities issued or insured by Ambac or Ambac Assurance.AAC. For public finance credits, including Puerto Rico, as well as other issuers, for which Ambac has an estimate of expected loss at March 31, 2020,2021, the possible increase in loss reserves under stress or other adverse conditions and circumstances was estimated to be approximately $1,220.$660. This possible increase in loss reserves under stress or other adverse conditions is significant and if we were to experience such incremental losses, our stockholders’ equity as of March 31, 20202021, would decrease from $1,062$1,123 to $(158). There$463. However, there can be no assurance that losses may not exceed such amount.
Representation and Warranty Recoveries:
Ambac records estimated RMBS R&W subrogation recoveries for breaches of R&Ws&W by sponsors of certain RMBS transactions. For a discussion of the approach utilized to estimate RMBS R&W subrogation recoveries, see Note 2. Basis of Presentation and Significant Accounting Policies in the Notes to Consolidated Financial Statements included Part II, Item 8 in the Company’s
Annual Report on Form 10-K for the year ended December 31, 2019.2020.
Ambac has recorded RMBS R&W subrogation recoveries of $1,764$1,748 ($1,7381,722 net of reinsurance) and $1,727$1,751 ($1,7021,725 net of reinsurance) at March 31, 20202021 and December 31, 2019,2020, respectively. R&W recovery proceeds up to the first $1,400 and above $1,600 have been pledged as security on certain of Ambac's long-term debt obligations as described further in Note 1.

actual or projected collateral performance, changes in the creditworthiness of a sponsor and/or the projected timing of recoveries.
Our ability to realize R&W subrogation recoveries is subject to significant uncertainty, including risks inherent in litigation;litigation, including adverse rulings or decisions in our cases or in litigations to which AAC is not a party that set precedents or resolve questions of law that impact our own claims; collectability of such amounts from counterparties (and/or their respective parents and affiliates); timing of receipt of any such recoveries; intervention by OCI, which could impede our ability to take actions required to realize such recoveries; and uncertainty inherent in the assumptions used in estimating such recoveries. Failure to realize R&W subrogation recoveries for any reason or the realization of R&W subrogation recoveries materially below the amount recorded on Ambac's consolidated balance sheet would have a material adverse effect on our results of operations and financial condition andcondition. If we were unable to realize R&W subrogation recoveries recorded on Ambac's consolidated balance sheet, our stockholders’ equity as of March 31, 2021, would decrease from $1,123 to $(598). Additionally, failure to realize R&W subrogation recoveries, or the realization of recoveries significantly below those recorded on the balance sheet, may result in adverse consequences such as impairing the ability of Ambac AssuranceAAC to honor its financial obligations; the initiation of rehabilitation proceedings against Ambac Assurance; decreased likelihood of Ambac Assurance deliveringAAC; AAC not being able to deliver value to Ambac, through dividends or otherwise; and a significant drop in the value of securities issued or insured by Ambac or AAC.
Credit Impairment for Reinsurance Recoverables:
The key indicator management uses to assess the credit quality of reinsurance recoverables is collateral posted by the reinsurers and independent rating agency credit ratings. For the majority of reinsurance contracts where Ambac Assurance.has recorded a recoverable, the fair value of collateral posted by the reinsurer to AAC exceeds AAC's reinsurance recoverable carrying value, net of ceded premiums payable. AAC has uncollateralized credit exposure of $4 and $1 and has recorded an allowance for credit losses of $— and $— at March 31, 2021 and December 31, 2020

7.8. FAIR VALUE MEASUREMENTS
The Fair Value Measurement Topic of the ASC establishes a framework for measuring fair value and disclosures about fair value measurements.
Fair Value Hierarchy:
The Fair Value Measurement Topic of the ASC specifies a fair value hierarchy based on whether the inputs to valuation techniques used to measure fair value are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Company-based assumptions. The fair value hierarchy prioritizes model inputs into three broad levels as follows:
lLevel 1Quoted prices for identical instruments in active markets. Assets and liabilities classified as Level 1 include US Treasury and other foreign government obligations traded in highly liquid and transparent markets, certain highly liquid pooled fund investments, exchange traded futures contracts, variable rate demand obligations and money market funds.
lLevel 2Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Assets and liabilities classified as Level 2 generally include investments in fixed incomematurity securities representing municipal, asset-backed and corporate obligations, certain interest rate swap contracts and most long-term debt of variable interest entities consolidated under the Consolidation Topic of the ASC.
lLevel 3Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. This hierarchy requires the use of observable market data when available. Assets and liabilities classified as Level 3 include credit derivative contracts, certain uncollateralized interest rate swap contracts, equity interests in Ambac sponsored special purpose entities and certain investments in fixed incomematurity securities. Additionally, Level 3 assets and liabilities generally include loan receivables, and certain long-term debt of variable interest entities consolidated under the Consolidation Topic of the ASC.

The Fair Value Measurement Topic of the ASC permits, as a practical expedient, the estimation of fair value of certain investments in funds using the net asset value per share of the investment or its equivalent (“NAV”). Investments in funds valued using NAV are not categorized as Level 1, 2 or 3 under the fair value hierarchy. The following table sets forth the carrying amount and fair value of Ambac’s financial assets and liabilities as of March 31, 20202021 and December 31, 2019,2020, including the level within the fair value hierarchy at which fair value measurements are categorized. As required by the Fair Value Measurement Topic of the ASC, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Determination of Fair Value:
When available, Ambac uses quoted active market prices specific to the financial instrument to determine fair value, and classifies such items within Level 1. The determination of fair value for financial instruments categorized in Level 2 or 3 involves judgment due to the complexity of factors contributing to the valuation. Third-party sources from which we obtain independent market quotes also use assumptions, judgments and estimates in determining financial instrument values and different third parties may use different methodologies or provide different values for
financial instruments. In addition, the use of internal valuation models may require assumptions about hypothetical or inactive markets. As a result of these factors, the actual trade value of a financial instrument in the market, or exit value of a financial instrument position by Ambac, may be significantly different from its recorded fair value.
Ambac’s financial instruments carried at fair value are mainly comprised of investments in fixed incomematurity securities, equity interests in pooled investment funds, derivative instruments,

certain variable interest entity assets and liabilities and interests in Ambac sponsored special purpose entities. Valuation of financial instruments is performed by Ambac’s finance group using methods approved by senior financial management with consultation from risk management and portfolio managers as appropriate. Preliminary valuation results are discussed with portfolio managers quarterly to assess consistency with market transactions and trends as applicable. Market transactions such as trades or negotiated settlements of similar positions, if any, are reviewed to validate fair value model results. However, many of the financial instruments valued using significant unobservable inputs have very little or no observable market activity. Methods and significant inputs and assumptions used to determine fair values across portfolios are reviewed quarterly by senior financial management. Other valuation control procedures specific to particular portfolios are described further below.
Fixed IncomeMaturity Securities:
The fair values of fixed incomematurity investment securities are based primarily on market prices received from broker quotes or alternative pricing sources. Because many fixed incomematurity securities do not trade on a daily basis, pricing sources apply available market information through processes such as matrix pricing to calculate fair value. Such prices generally consider a variety of factors, including recent trades of the same and similar securities. In those cases, the items are classified within Level 2. For those fixed incomematurity investments where quotes were not available or cannot be reasonably corroborated, fair values are based on internal valuation models. Key inputs to the internal valuation models generally include maturity date, coupon and yield curves for asset-type and credit rating characteristics that closely match those characteristics of the specific investment securities being valued. Items valued using valuation models are classified according 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 there may be significant inputs that are readily observable. Longer (shorter) expected maturities or higher (lower) yields used in the valuation model will, in isolation, result in decreases (increases) in fair value. Generally, lower credit ratings or longer expected maturities will be accompanied by higher yields used to value a security. At March 31, 2020,2021, approximately 4%3%, 94%95% and 2% of the fixed incomematurity investment portfolio
(excluding (excluding variable interest entity investments) was valued using broker quotes, alternative pricing sources and internal valuation models, respectively. At December 31, 2019,2020, approximately 4%2%, 94%95% and 2%3% of the fixed incomematurity investment portfolio (excluding variable interest entity investments) was valued using broker quotes, alternative pricing sources and internal valuation models, respectively.
Ambac performs various review and validation procedures to quoted and modeled prices for fixed incomematurity securities, including price variance analyses, missing and static price reviews, overall valuation analysis by portfolio managers and finance managers and reviews associated with our ongoing impairment analysis. Unusual prices identified through these procedures will be evaluated further against alternative third party quotes (if available) and/or, internally modeled prices and/or other relevant data, and the pricing source values will be challenged as necessary. Price challenges generally result in the use of the pricing source’s quote as originally provided or as revised by the source following
their internal diligence process. A price challenge may result in a determination by either the pricing source or Ambac management that the pricing source cannot provide a reasonable value for a security or cannot adequately support a quote, in which case Ambac would resort to using either other quotes or internal models. Results of price challenges are reviewed by portfolio managers and finance managers.
Information about the valuation inputs for fixed incomematurity securities classified as Level 3 is included below:
Other asset-backed securities: This security is a subordinated tranche of a resecuritizationsecuritization collateralized by Ambac-insured military housing bonds. The fair value classified as Level 3 was $66$76 and $72$78 at March 31, 20202021 and December 31, 2019,2020, respectively. Fair value was calculated using a discounted cash flow approach with expected future cash flows discounted using a yield consistent with the security type and rating. Significant inputs for the valuation at March 31, 20202021 and December 31, 20192020 include the following:

Other Investments:
Other investments primarily relate to investments in pooled investment funds. The fair value of pooled investment funds is determined using dealer quotes or alternative pricing sources when such investments have readily determinable fair values. When fair value is not readily determinable, pooled investment funds are valued using NAV as a practical expedient as permitted under the Fair Value Measurement Topic of the ASC. Refer to Note 8.

quotes are not available, fair value is determined using valuation models. These valuation models require market-driven inputs, including contractual terms, credit spreads and ratings on underlying referenced obligations, yield curves and tax-exempt interest ratios. The valuation of certain derivative contracts also require the use of data inputs and assumptions that are determined by management and are not readily observable in the market. Under the Fair Value Measurement Topic of the ASC, Ambac is required to consider its own credit risk when measuring the fair value of derivatives and other liabilities. Factors considered in estimating the amount of any Ambac credit valuation adjustment ("CVA") on such contracts include collateral posting provisions, right of set-off with the counterparty, the period of time remaining on the derivative and the pricing of recent terminations. The aggregated Ambac CVA impact reduced the fair value of credit derivative liabilities was reduced by $0 and $0less than a million dollars at both March 31, 20202021 and December 31, 2019,2020, respectively as a result of incorporating an Ambac CVA into the valuation model for these contracts. Interest rate swap liabilities are collateralized and are not adjusted with an Ambac CVA at March 31, 2020 and December 31, 2019.
Interest rate swaps that are not centrally cleared are valued using vendor-developed models that incorporate interest rates and yield curves that are observable and regularly quoted. These models provide the net present value of the derivatives based on contractual terms and observable market data. Generally, the need for counterparty (or Ambac) CVAs on interest rate derivatives is mitigated by the existence of collateral posting agreements under which adequate collateral has been posted. Certain of these derivative contracts entered into with financial guarantee customers are not subject to collateral posting agreements. Counterparty credit risk related to such customer derivative assets is included in our determination of their fair value.
Ambac's remaining credit derivatives ("CDS") are valued using an internal model that uses traditional financial guarantee CDS pricing to calculate the fair value of the derivative contract based on the reference obligation's current pricing, remaining life and credit rating and Ambac's own credit risk. The model calculates the difference between the present value of the projected fees receivable under the CDS and our estimate of the fees a financial guarantor of comparable credit quality would charge to provide the same protection at the balance sheet date. Unobservable inputs used include Ambac's internal reference obligation credit ratings and expectedremaining life, estimates of fees that would be charged to assume the credit derivative obligation and Ambac's CVA. Ambac is party to
only one remaining credit derivative with an internal credit rating of AA at March 31, 2020.2021. Ambac has not made any significant changes to its modeling techniques or related model inputs for the periods presented.
Financial Guarantees:
Fair value of net financial guarantees written represents our estimate of the cost to Ambac to completely transfer its insurance obligation to another market participant of comparable credit worthiness. In theory, this amount should be the same amount that another market participant of comparable credit worthiness would hypothetically charge in the market place,marketplace, on a present value basis, to provide the same protection as of the balance sheet date. This fair value estimate of financial guarantees is presented on a net basis and includes direct and assumed contracts written, net of ceded reinsurance contracts.
Long-term Debt:
Long-term debt includes Ambac AssuranceAAC surplus notes and junior surplus notes, the Ambac Note and Tier 2 Notes issued in connection with the Rehabilitation Exit Transactions and the Ambac UK debt issued in connection with the Ballantyne commutation. The fair values of surplus notes, the Ambac Note and Tier 2 Notes are classified as Level 2. The fair value of junior surplus notes and Ambac UK debt are classified as Level 3.
Other Financial Assets and Liabilities:
Included in Other assets are Loans and Ambac’s equity interest in an Ambac sponsored VIE established to provide certain financial guarantee clients with funding for their debt obligations. The fair values of these financial assets are estimated based upon internal valuation models and are classified as Level 3.
Variable Interest Entity Assets and Liabilities:
The financial assets and liabilities of FG VIEs consolidated under the Consolidation Topic of the ASC consist primarily of fixed incomematurity securities and loans held by the VIEs, derivative and debt instruments and notes issued by the VIEs which are generally carried at fair value. These consolidatedreported as long-term debt. As described in Note 3. Variable Interest Entities, these FG VIEs are securitization entities which have liabilities and/or assets guaranteed by Ambac AssuranceAAC or Ambac UK.
The fair values of FG VIE long-term debt instruments are determined using the same methodologies used to value Ambac’s fixed income securities in its investment portfolio as described above. VIE debt fair value is based on market pricesprice quotes received from independent market sources.sources when available. Such quotes are considered Level 2 and generally consider a variety of factors, including recent trades of the same and similar securities.

Comparable to the sensitivities of investments in fixed incomematurity securities described above, longer (shorter) expected maturities or higher (lower) yields used in the valuation model will, in isolation, result in decreases (increases) in fair value liability measurement for FG VIE long-term debt.
FG VIE derivative asset and liability fair values are determined using vendor-developed valuation models. Whenmodels, which incorporated observable market data related to specific derivative contractual terms are available and may be valued primarily by reference toincluding interest rates, foreign exchange rates and yield curves that are observable and regularly quoted, the derivatives are valued using vendor-developed models.

The fair value of FG VIE fixed maturity securities and loan assets are obtainedbased on Level 2 market price quotes received from independent market quotessources when available. Typically, FG VIE asset fair values are not readily available from market quotes and are estimated internally. The consolidated VIEs are entities in which net cash flows from assets and derivatives (after adjusting for financial guarantor cash flows and other expenses) will be paid out to note holders or equity interests. Internal valuationsvaluation of VIE assets (fixed incomeeach FG VIE’s fixed maturity securities or loans), therefore,loan assets are generally derived from the fair valuevalues of the notes issued by the respective VIE and the VIE’s derivatives, determined as described above, adjusted for the fair valuevalues of cash flows from Ambac’s financial guarantee.guarantees associated with the VIE. The fair value of financial guarantee cash flows include:guarantees consist of: (i) estimated future premiumspremium cash flows discounted at a rate consistent with that implicit in the fair value of the VIE’s liabilities and (ii) internal estimates of future lossclaim payments by Ambac discounted at a rate that includes Ambac’s own credit risk. Estimated future premium payments to be paid by the VIEs were discounted at a par-weightedweighted average rate of 2.5%2.8% and 2.7%2.4% at March 31, 20202021 and December 31, 2019,2020, respectively. At March 31, 2020,2021, the range of these discount rates was between 2.3% and 11.0%3.5%. The value of future loss payments to be paid by Ambac to the VIEs was adjusted to include an Ambac CVA appropriate for the term of expected Ambac claim payments.

Additional Fair Value Information for Financial Assets and Liabilities Accounted for at Fair Value:
The following tables present the changes in the Level 3 fair value category for the periods presented in 20202021 and 2019.2020. Ambac classifies financial instruments in Level 3 of the fair value hierarchy when there is reliance on at least one significant unobservable input to the valuation model. In addition to these unobservable inputs, the valuation models for Level 3 financial instruments typically also rely on a number of inputs that are readily observable either directly or indirectly. Thus, the gains and losses presented below include changes in the fair value related to both observable and unobservable inputs.

Management has determined that the securities in the above table do not have credit impairment as of March 31, 20202021 and December 31, 2019,2020, based upon various factors, including (i) no actual or expected principal and interest payment defaults on these securities; (ii) analysis of the creditworthiness of the issuer and financial guarantor, as applicable, and (iii) for debt securities that are non-highly rated beneficial interests in securitized financial assets, analysis of whether there was an adverse change in projected cash flows. Management's evaluation as of March 31, 20202021, includes the expectation that all principal and interest payments on securities guaranteed by Ambac AssuranceAAC or Ambac UK will be made timely and in full.
As of March 31, 2020, corporate securities in an unrealized loss position included $456 of Secured Notes issued by Ambac LSNI with an unrealized loss $24. The Secured Notes are insured under a financial guarantee policy issued by Ambac Assurance. Corporate
securities also included $12 million of other non-investment grade securities with an aggregate gross unrealized loss of $4. The determination that these securities were not credit impaired was based on a security level assessment of default probability derived from historical data for the applicable asset class and credit rating. This assessment also considered the potential increased risk under a stressed macroeconomic environment. The remaining corporate securities carry investment grade credit ratings and suffered temporary price declines consistent with the broader bond market. There are no expected defaults among these securities.
Residential mortgage backed securities ("RMBS") and other asset backed securities in an unrealized loss position at March 31, 2020, are primarily RMBS and student loan securities guaranteed by Ambac Assurance. For these securities, management compared the present value of cash flows expected to be collected to the amortized cost basis of the securities to assess whether the amortized cost will

(Dollar Amounts in Millions, Except Share Amounts)

be recovered. Cash flows considered full payment of interest and principal through Ambac's financial guarantee. For floating rate securities, future cash flows were adjusted to reflect changes in the index rate applicable to each security as of the evaluation date. Cash flows were discounted at the effective interest rate. Adverse changes in cash flows attributable solely to changes in the index rate of securities are not considered impaired.
Collateralized debt obligations in an unrealized loss position at March 31, 2020, are highly rated collateralized loan obligations ("CLOs"). The CLO market experienced indiscriminate price declines as certain market participants sought to generate excess liquidity. Management determined that these price declines are temporary and that the CLOs are not credit impaired as of March 31, 2020.
Ambac’s assessment about whether a decline in valuesecurity is other-than-temporarycredit impaired reflects management’s current judgment regarding facts and circumstances specific to athe security and other factors. If that judgment changes, Ambac may record a charge for credit impairment in future periods.

Credit Derivatives:
Credit derivatives, which are privately negotiated contracts, provide the counterparty with credit protection against the occurrence of a specific event such as a payment default or bankruptcy relating to an underlying obligation. Credit derivatives issued are insured by Ambac Assurance. None of theAAC. The outstanding credit derivative transactionstransaction at March 31, 2020,2021, does not include ratings basedratings-based collateral-posting triggers or otherwise require Ambac to post collateral regardless of Ambac’s ratings or the size of the mark to market exposure to Ambac.
The portfolio of ourOur credit derivatives were written on a “pay-as-you-go” basis. Similar to an insurance policy, execution, pay-as-you-go provides that Ambac pays interest shortfalls on the referenced transaction as

Contingent Features in Derivatives Related to Ambac Credit Risk
Ambac’s over-the-counter interest rate swaps are centrally cleared when eligible. Certain interest rate swaps remain with professional swap-dealer counterparties and direct customer counterparties. These non-cleared swaps are generally executed under standardized derivative documents including collateral support and master netting agreements. Under these agreements, Ambac is required to post collateral in the event net unrealized losses exceed

(Dollar Amounts in Millions, Except Share Amounts)

predetermined threshold levels. Additionally, given that Ambac AssuranceAAC is no longer rated by an independent rating agency, counterparties have the right to terminate the swap positions.
As of March 31, 20202021 and December 31, 2019,2020, the net liability fair value of derivative instruments with contingent features linked to Ambac’s own credit risk was $132$85 and $89,$113, respectively, related to which Ambac had posted cash and securities as collateral with a fair value of $154$103 and $109,$130, respectively. All such ratings-based contingent features have been triggered requiring maximum collateral levels to be posted by Ambac while preserving counterparties’ rights to terminate the contracts. Assuming all such contracts terminated at fair value on
March 31, 2020,2021, settlement of collateral balances and net derivative liabilities would result in a net receipt of cash and/or securities by Ambac. If counterparties elect to exercise their right to terminate, the actual termination payment amounts will be determined in accordance with derivative contract terms, which may result in amounts that differ from market values as reported in Ambac’s financial statements.
10.11. INCOME TAXES
AFG files a consolidated Federal income tax return with its subsidiaries. AFG and its subsidiaries also file separate or combined income tax returns in various states, local and foreign jurisdictions. The following are the major jurisdictions in which Ambac and its subsidiaries operate and the earliest tax years subject to examination:

In accordance with the Income Tax Topic of the ASC, a valuation allowance is recognized if, based on the weight of available evidence, it is more-likely-than-not that some, or all, of the deferred tax asset will not be realized. As a result of the risks and uncertainties associated with future operating results, management believes it is more likely than not that the Company will not generate sufficient U.S. federal, state and/or local taxable income to recover theits deferred tax operating assets and therefore maintains a full valuation allowance.

NOL Usage
Pursuant to the intercompany tax sharing agreement, to the extent Ambac Assurance generates taxable income after September 30, 2011, which is offset with "Allocated NOLs" of $3,650, it is obligated to make payments (“Tolling Payments”), subject to certain credits, to Ambac in accordance with the following NOL usage table, where the “Applicable Percentage” is applied to the aggregate amount of federal income tax liability that would have been paid if the Allocated NOLs were not available. Pursuant to the Closing Agreement between Ambac and the Internal Revenue Service ("IRS"), the IRS will receive 12.5% of Tier C and 17.5% of Tier D payments, if made.

As of December 31, 2018, Ambac Assurance generated cumulative taxable income of $1,508, leaving $2,142 of the $3,650 Allocated NOLs subject to Tolling Payments. For the year ended December 31, 2019, and three months ended March 31, 2020, Ambac Assurance generated NOLs of approximately $143 and $172, respectively, which will need to be utilized before any new Tolling Payments will be generated.
If not utilized, the NOLs will begin expiring in 2029, and will fully expire in 2040, with the exception of the tax loss generated during the three months ended March 31, 2020 of approximately $168, which if Ambac remains in a loss position at year end 2020, will expire in 2041.
As a result of positive income at Ambac Assurance in 2017, Ambac accrued $28 of tax tolling payments. In May 2018, Ambac executed a waiver under the intercompany tax sharing agreement pursuant to which Ambac Assurance was relieved of the requirement to make the 2017 tax tolling payment by June 1, 2018.  Ambac also agreed to continue to defer receipt of the 2017 tax tolling payment from

Ambac Assurance until such time as OCI consents to the payment. While OCI has not defined the conditions under which it will consent to the 2017 tax tolling payment, OCI has indicated that it will consider a number of factors, including asset quality and loss and reserve trends. We can provide no assurance as to whether, or when, OCI will consent to the 2017 tax tolling payment.
Ambac's tax positions are subject to review by the OCI, which may lead to the adoption of positions that reduce the amount of tolling payments otherwise available to Ambac.
As of March 31, 2020, the remaining balance of the $3,650 NOL allocated to Ambac Assurance, and new NOLs accrued during 2019 & 2020, totaled approximately $2,457. As of March 31, 2020 the consolidated group's NOL is approximately $3,703, of which Ambac's NOL was approximately$1,246.

Ambac Assurance’sAAC’s estimates of projected losses for RMBS transactions consider, among other things, the RMBS transactions’ payment waterfall structure, including the application of interest and principal payments and recoveries, and depend in part on our interpretations of contracts and other bases of our legal rights. From time to time, bond trustees and other transaction participants have employed different contractual interpretations and have commenced, or threatened to commence, litigation to resolve these differences. It is not possible to predict whether additional disputes will arise, nor the outcomes of any potential litigation. It is possible that there could be unfavorable outcomes in this or other disputes or proceedings and that our interpretations may prove to be incorrect, which could lead to changes to our estimate of loss reserves.
Ambac AssuranceAAC has periodically received various regulatory inquiries and requests for information with respect to investigations and inquiries that such regulators are conducting. Ambac AssuranceAAC has complied with all such inquiries and requests for information.
The Company is involved from time to time in various routine legal proceedings, including proceedings related to litigation with present or former employees. Although the Company’s litigation with present or former employees is routine and incidental to the conduct of its business, such litigation can result in large monetary awards when a civil jury is allowed to determine compensatory and/or punitive damages for, among other things, termination of employment that is wrongful or in violation of implied contracts.
From time to time, Ambac is subject to allegations concerning its corporate governance that may lead to litigation, including derivative litigation, and while the monetary impacts may not be material, the matters may distract management and the Board of Directors from their principal focus on Ambac's business, strategy and objectives.
It is not reasonably possible to predict whether additional suits will be filed or whether additional inquiries or requests for information will be made, and it is also not possible to predict the outcome of litigation, inquiries or requests for information. It is possible that there could be unfavorable outcomes in these or other proceedings. Legal accruals for litigation against the Company which are probable and reasonably estimable, and management's estimated range of loss for such matters, are either
not applicable or are not material to the operating results or financial position of the Company. For the litigation matters the Company is defending that do not meet the “probable and reasonably estimable” accrual threshold and where no loss estimates have been provided above, management is unable to make a meaningful estimate of the amount or range of loss that could result from unfavorable outcomes. 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 above and, to the extent that these actions proceed, the Company intends to defend itself vigorously; however, the Company is not able to predict the outcomes of these actions.
Litigation Filed or Joined by Ambac
In the ordinary course of their businesses, certain of Ambac’s subsidiaries assert claims in legal proceedings against third parties to recover losses already paid and/or mitigate future losses. The amounts recovered and/or losses avoided which may result from these proceedings is uncertain, although recoveries and/or losses avoided in any one or more of these proceedings during any quarter or fiscal year could be material to Ambac’s results of operations in that quarter or fiscal year.
Puerto Rico
Financial Oversight and Management Board for Puerto Rico v. Public Buildings Authority (United States District Court, District of Puerto Rico, No. 1:18-ap-00149, filed December 21, 2018). On December 21, 2018, the Oversight Board, together with the Committee, as Plaintiffs, filed a complaint against the Puerto Rico Public Buildings Authority (“PBA”) seeking declaratory judgment that the leases between PBA and its lessees-many of whom are agencies and instrumentalities of the Commonwealth-are “disguised financings,” not true leases, and therefore should not be afforded administrative expense priority under the Bankruptcy Code. On March 12, 2019, Ambac Assurance and other interested parties were permitted to intervene in order to argue that the PBA leases are valid leases, and are entitled to administrative expense treatment under the Bankruptcy Code. On June 16, 2019, the Oversight Board announced that it had entered into a plan support agreement ("PSA") with certain general obligation and PBA bondholders that includes a proposed resolution of claim objections to and issues surrounding both general obligation and PBA bonds, including a proposed settlement of this adversary proceeding. On July 24, 2019, the District Court referred this matter to mediation and ordered it stayed during the pendency of such mediation. On September 27, 2019, the Oversight Board filed a joint plan of adjustment and disclosure statement for the Commonwealth, PBA, and the Employees’ Retirement System for Puerto Rico. On February 9, 2020, the Oversight Board executed a new plan support agreement with additional creditors (the “New PSA”) and announced that it intends to file, and seek to confirm, the Amended POA. On March 10, 2020, the District Court ordered that this case remain stayed while the Oversight Board attempts to confirm the Amended POA.

objection in the Commonwealth’s Title III case challenging claims arising from certain general obligation bonds issued by the Commonwealth in 2012 and 2014 totaling approximately $6 billion, none of which are held or insured by Ambac Assurance. The court subsequently ordered certain consolidated procedures permitting parties in interest an opportunity to participate in litigation of the objection. On April 11, 2019, Ambac Assurance filed a notice of participation in support of the objection, advancing the argument, among other things, that the PBA leases are true leases, but the associated debt nonetheless should be included in the Commonwealth’s debt ceiling calculation such that the 2012 and 2014 general obligation bond issuances are null and void and claims arising therefrom should be disallowed. On June 16, 2019, the Oversight Board announced that it had entered into a PSA with certain general obligation and PBA bondholders that includes a proposed resolution of claim objections to and issues surrounding both general obligation and PBA bonds, including a proposed settlement of this omnibus claim objection. On June 25, 2019, the Oversight Board moved to stay proceedings related to this omnibus claim objection while it pursues confirmation of the plan contemplated in the PSA. On July 24, 2019, the District Court referred this matter to mediation and ordered it stayed during the pendency of such mediation. On February 5, 2020, certain parties filed motions to dismiss the claim objection. On February 9, 2020, the Oversight Board executed the New PSA and announced that it intends to file, and seek to confirm, the Amended POA. Additional motions to dismiss were filed on February 19, 2020.

On January 16, 2020, the First Department recalled and vacated its September 17, 2019 decision and order and substituted a new decision and order.

AAC and Subsidiaries
A key strategy for Ambac is to increase the value of its investment in Ambac AssuranceAAC by actively managing its assets and liabilities. Asset management primarily entails maximizing the risk adjustedrisk-adjusted return on non-VIE invested assets and managing liquidity to help ensure resources are available to meet operational and strategic cash needs. These strategic cash needs include activities associated with Ambac's liability management and loss mitigation programs.
Asset Management:Management
Investment portfolios are subject to internal investment guidelines, as well as limits on types and quality of investments imposed by applicable insurance laws and regulations. As part of its investment strategy, and in accordance with the aforementioned guidelines, Ambac Assurance and Ambac UK, a subsidiary of Ambac Assurance, purchase distressed Ambac-insured securities based on their relative risk/reward characteristics. The investment portfolios of Ambac AssuranceAAC and Ambac UK also hold fixed incomematurity securities and various pooled investment funds. Refer to

Liability and Insured Exposure Management:Management
Ambac Assurance'sAAC's Risk Management Group focuses on the analysis, implementation and execution of commutations, risk reduction, or defeasance and loss recovery strategies. Analysts evaluate the estimated timing and severity of projected policy claims as well as the potential impact of loss mitigation or remediation strategies in order to target and prioritize policies, or portions thereof, for commutation, reinsurance, refinancing, restructuring or other risk reduction strategies. For targeted policies, analysts will engage with issuers, bondholders and other economic stakeholders to negotiate, structure and execute such strategies. During 2020,2021, successful risk reduction transactions included:

Additionally, total net par outstanding reduced as a result of the weakening of British Pounds as compared to US Dollars.

COVID-19
In March 2020, the outbreak of COVID-19, caused by a novel strain of the coronavirus, was recognized as a pandemic by the World Health Organization, and the outbreak is now widespread globally, including in the markets in which we operate. The COVID-19 outbreakpandemic has had, and continues to have, a notable impact on general economic conditions, including but not limited to a sharp spikehigher unemployment; volatility in unemployment; a broad based and significant decrease in asset valuations;the capital markets; closure or severe curtailment of the operations and, hence,
revenues, of many businesses and public and private enterprises to which we are directly or indirectly exposed, such as hotels, restaurants, sports and entertainment facilities, airports and other transportation facilities, and retail establishments, mostly due to shelter-in-place orders, social distancing guidelines, travel bans and restrictions, and business shutdowns. In addition, in March 2020 a disagreement between Russiarestrictions and Saudi Arabia over oil production quotas led to a sudden and sharp decline in oil prices which have subsequently fallen to historic lows. Accordingly, we are now in a global recession with most large economies experiencing negative growth. shutdowns.
In the U.S., significant monetary policy andactions, fiscal stimulus particularlymeasures and other relief measures have helped to moderate the negative economic impacts of COVID-19, and have supported the economic recovery which began in the second half of 2020 and continues into 2021. These measures include monetary policy decisions, such as quantitative easing, providing liquidity to financial institutions, providing liquidity to credit markets and the Paycheck Protection Program Lending Facility; Congressional fiscal stimulus and other actions, such as the $1.9 trillion American Rescue Plan Act or ARPA, which was enacted in March 2021, and a number of programs enacted in 2020, including the $2.4 trillion Coronavirus Aid, Relief and Economic Security ("CARES") Act, the $483 billion Paycheck Protection Program And Health Care Enactment Act, the $190 billion Families First Coronavirus Response Act, and the $920 billion 2021 Consolidated Appropriations Act. Collectively, these programs provide, among other things, direct payments to households, support for small businesses, renter assistance and funding for transport, airlines, healthcare, education and state and local governments. In addition, housing measures, such as forbearance on mortgages and suspension of foreclosures and evictions, and various executive orders have helped to provide relief. Outside of the U.S., and in the United Kingdom and Italy in particular, where Ambac has insured portfolio exposure, various monetary policy, fiscal stimulus measures and other actions have helped to moderate the economic impactimpact.
In the U.S., the economic recovery, which began in the second half of COVID-19, along with2020, continues through the first quarter of 2021, supported by the aforementioned monetary policy and fiscal stimulus measures as well as a rapidly increasing COVID 19 vaccination rate. Economic recovery and, in particular, fiscal stimulus measures such as the $350 billion of assistance earmarked for state and local governments under ARPA and other actions takenfunding to support households under ARPA and other programs, should be an overall benefit to most issuers in Ambac's insured portfolio negatively impacted by governments outside the U.S.; however,COVID-19 pandemic. Nonetheless, credit risk in the insured portfolio remains a concern given theelevated due to, among other things, uncertainty over the severitytrajectory and durationcontinuity of the economic recovery due to still high COVID-19 related disruption.
COVID-19 has impacted Ambac's operating environment. Ambac has implemented a COVID-19 response plan designed to ensureinfection rates globally as well as the safetyspread of our staff and business continuity. Our employees have transitioned to working remotely while maintaining full operational capabilities. We have not experienced and do not anticipate incurring material incremental operating expenditures to maintain the current remote operating environment.new virus variants. In addition, to our own staff, Ambac's critical third-party service providers are operating remotelythe near-term efficacy of fiscal stimulus and therefore we have conducted a review of these service providers and have not presently identified or experienced any limitations or operational constraints with respect to services providedrelated measures on certain exposures in the current environment. Ambac does not believe that our current operating environment has resulted in a significant changeinsured portfolio impacted by the COVID-19 pandemic, such as those with exposure to our disclosure controls or internal controls over financial reporting.the performance of hotels, restaurants, and entertainment centers, is uncertain.
Since 2020, COVID-19 has adversely impacted Ambac's financial position and results of operations as credit risk in the insured and investment portfolios has increased. Municipal, project finance,In the insured portfolio, municipal, mortgage-backed and student loan sectors, and other asset securitizations, in particular,securitization exposures have been adversely impacted and, despite the ongoing economic recovery, could still be materially adversely impacted in the future. We are continuously evaluating and as a resultupdating our


| Ambac Financial Group, Inc. 4442 20202021 First Quarter FORM 10-Q|




we have increased loss reserves across each of these and other sectors during the three months ended March 31, 2020. We are continuously evaluating and updating our view of the macro economic environment as well as our specific credit view of each of our insured exposures considering the significant uncertainties brought upon us by the COVID-19 pandemic. The overall financial impact from COVID-19 has been and will be a function of (i) the willingness and ability of issuers of insured obligationsdebt and other counterparties to pay their obligations when due, whether due to operational or financial reasons;due; (ii) the impact of changes to interest rates on policy and derivative paymentspayments; and (iii) the performance of the investment portfolio.
Ambac’s insurance policies will be drawn in the event that the issuers of insured obligations do not make payments on their obligations when due. As a result of the COVID-19 related economic disruptionimpact on issuers and markets where Ambac provides financial guarantees,guarantees; including lower tax, project, and business revenues and increases in forbearances or delinquencies on mortgage and student loan payments, we have increased our loss reserves andacross affected exposures. The crisis may further increase them inalso impair certain issuers' ability to pay premiums owed to Ambac; however, we believe such issuers currently have the future depending on the duration and severity of the crisis. Ambac also hasability to continue to pay such premiums due from issuers; we currently do not expect any significant delay or increase in credit impairments with respect to insurance premiums,timely, but thatthis is subject to change.
Ambac has exposure to reinsurance counterparties for their portions of future claim payments. Ambac has reinsured approximately 13.8%15.8% of its gross par outstanding to fourfive reinsurance counterparties. Each of these reinsurance counterparties is experienced in the business of reinsuring and/or writing financial guaranty insurance. All have current ratings of A+ (by S&P) or better and have sufficient collateralization or replacement triggers upon downgrade. Ambac actively monitors each of these reinsurance entities and at presentcurrently believes they have the ability to perform under their respective reinsurance policies, but thatthis is subject to change.
Ambac is exposed to the risk that contractual counterparties (including those under our RMBS litigations and derivative counterparties) may default inon their financial obligations, whether as the result of insolvency, lack of liquidity, operational failure, fraud or other reasons. At present, Ambac has no concerns about the ability of our contractual counterparties, which include certain regulated exchanges in the case of interest rate swaps and futures, to perform under their contracts, but thatthis is also subject to change.
Asset prices have declined substantially during the quarter, particularly in directly affected industries such as tourism, airlines, hospitality, commercial real estate and manufacturing. While Ambac does not have significant investments in these asset classes, we did experience a negative total return for the investment portfolio of approximately (4.4)% during the three month period ending March 31, 2020.  We evaluated and did not recognize credit impairments on the investment portfolio as of such date. However, in early April 2020, we decided to monetize a material portion of our investments in certain assets classes; including corporate securities rated below the 'A 'rated category, all directly owned CMBS (other than Military Housing bonds and mostly 'AAA' rated), and approximately
50% of all CLOs (all rated investment grade). While these positions were sold at a net gain, future investment losses and impairments may be possible.
Given the economic uncertainties associated with the duration and effects of the COVID-19 pandemic, it is impossible to fully predict all of its consequences and, as a result, it is possible that our future operating results and financial condition may be materially adversely affected. Refer to "Financial Guarantees In Force",Force," "Results of Operations" and "Balance Sheet Commentary" for further financial details on the current impact from COVID-19.
With regard to Ambac's new business strategic objective, we continue to evaluate opportunities in a disciplined manner. Our evaluation process has been revised to incorporate consideration of the impact of COVID-19 on new business prospects as well as Ambac's existing business and operations. While we continue to pursue new business opportunities, we believe that the COVID-19 pandemic has caused a general slow down in activity as potential targets evaluate the financial and strategic impact of the pandemic on their businesses and due to the practical constraints of shelter-in-place orders, social distancing guidelines, travel bans and restrictions, and business shutdowns.

LIBOR Sunset
Ambac continuously monitors regulatory and industry developments related to the transition from LIBOR to alternative reference rates. On April 6, 2021, New York State passed legislation addressing the cessation of U.S. Dollar ("USD") LIBOR and specified a recommended benchmark replacement based on the Secured Overnight Financing Rate (SOFR) for certain legacy transactions. The Alternative Reference Rates Committee, the Federal Reserve Board and several industry associations and groups have expressed support for the new law and are encouraging comparable Federal legislation. While Ambac believes the New York LIBOR law is generally a positive step, there remains significant uncertainty about how it will be interpreted or challenged as well as about other aspects of the discontinuance of LIBOR, including the impact of any Federal legislation. See the risk factor "Uncertainties regarding the expected discontinuance of the London Inter-Bank Offered Rate or any other interest rate benchmark could have adverse consequences" found in Part I, Item 1A of Ambac’s Annual Report on Form 10-K for the year ended December 31, 2020. Also, for further background and information about management's evaluation of Ambac's potential exposures to LIBOR transition, see "Executive Summary — LIBOR Sunset" in Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Ambac’s Annual Report on Form 10-K for the year ended December 31, 2020.

COVID-19
COVID-19 and the public health responses by the US federal and state governments haveat the onset of the pandemic resulted in a shut down for several months of significant portions of the US economy, including areas that Ambac's insured obligors rely upon to generate the revenues and cash flows necessary to service debts we insure. Governments outside the US, in markets in which Ambac operates, havealso implemented similar measures to the US. Ambac has undertakenundertook a detailed analysis of the potential impact of the closure of certain portions of the US economy as well asand certain other economies, including the UK, Italy, and Australia, to assess the impact of the currentresulting global recessioneconomic contraction on its insured financial guarantee portfolio.

CARES ActFiscal Stimulus and Other Relief Measures:Monetary Policy
The $2.2 trillion Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") provides relief andIn the U.S., significant fiscal stimulus funds for American consumers, businesses and industries impacted by COVID-19.
The CARES Act has several measures, that impacted US municipalitiesmonetary policy actions and other borrowers, including consumers, such as mortgagerelief measures have helped to moderate the negative economic impacts of COVID-19 and student loan borrowers, representedhave supported the economic recovery which began in our insured portfolio, including:
$500 billionthe second half of 2020 and continues into 2021. These measures include the $1.9 trillion American Rescue Plan Act or ARPA, signed into law in March 2021, which together with other fiscal stimulus measures put in place in 2020, provide for, direct lending, loans, loan guarantees and investments to eligible businesses, states and municipalities, including $25 billion dedicated to passenger airlines and $4 billion dedicated to cargo airlines;
$659 billion for small business loans (Paycheck Protection Program, as amended by the Paycheck Protection Program and Health Care Enhancement Act (“PPP & HCE Act”));
$150 billion allocation of direct aidamong other things, funding to state and local governments, to reimburse them for the costs of dealing with COVID-19;

financial institutions and credit markets. In addition, housing measures, such as forbearance on mortgages and suspension of foreclosures and evictions, and various executive orders have helped to provide relief. Outside of the US, and in the United Kingdom and Italy in particular, where Ambac has insured portfolio exposure, various monetary policy, fiscal stimulus measures and other actions have helped to moderate the negative economic impact and support recovery.
We are continuously evaluating and updating our view of the macro economic environment as well as our specific credit view of each of our insured exposures considering the significant uncertainties brought upon us by the COVID-19 pandemic.
Despite the above provisions,measures, which are designed to help mitigate the economic impact of the COVID-19 pandemic generally, the CARES Act contains certain provisions thatof these measures may adversely affect Ambac.
The CARES Act temporarily suspended payments on all student loans held by the Department of Education through September 30, 2020. Although it is unclear what impact this CARES Act provision will have on the private student loans owned by special purpose entities that have their securitized obligations guaranteed by Ambac Assurance, we have incorporated into our loss reserves analysis assumptions related to increased delinquencies for borrowers with private student loans who often also have federal student loans and may elect not to pay altogether. Despite the assumed increase in delinquencies and losses related to this potential phenomena as well as the general deterioration in consumer credit related to the economic downturn, Ambac Assurance does not anticipate making substantial claim payments on insured student loan transactions for several years due to the structures governing the insured bonds.
Additionally, These include the federal government has providedgovernment's temporary relief measures to which servicers of mortgage loans must adhere. The Federal Housing Administration ("FHA") of the US Department of Housing and Urban Development and the Federal Housing Finance Agency ("FHFA") are providing temporary relief measures that require mortgage loan servicers to offer relief to borrowers who suffer hardship as a result of COVID-19. The relief measures announced include a 60-day moratoriummoratoriums on foreclosures and
evictions andas well as the expansion of forbearance and subsequent repayment options. Such servicers are generally applying these guidelines to non-FHFA loans, including those loans owned by special purpose entities that have their securitized obligations guaranteed by Ambac Assurance. Moreover, several State agencies have issued similar guidanceAAC. Forbearances increased sharply across the AAC's insured first lien RMBS obligations during the second quarter of 2020 and early in the third quarter of 2020, but then dropped later in the third quarter of 2020 through March 31, 2021, albeit to mortgage loan servicers concerning loanstill elevated levels. The ultimate impact of forbearances and other relief for borrowers. Dependingmeasures, such as foreclosure and eviction moratoriums, on the severity and length of the economic downturn, there may be increasing pressure to extend the duration of forbearances and subsequently to offer generous repayment plans. While the impact of these and other forbearance measures on Ambac Assurance'sAAC's insured RMBS obligations are unclear,still unclear. However, we have assumed that such measures as well as the economic impact of the global recession, will have an adverse impact on delinquencies and home price appreciation for the mortgages that underlie our insured RMBS transactions. Consequently, we have anticipated that we will experience an increase in claim payments for certain of our insured RMBS obligations. However, we also anticipate that the significant decline in interest rates experienced during the first quarter of 2020 will likely generate additional excess spread recoveries on insured RMBS obligations that will likely more than compensate for such adverse effects.

In addition to, as well as in connection with the CARES Act, the Federal Reserve has implemented a number of programs to improve liquidity and the functioning of the financial markets in an effort to help mitigate the impact of the COVID-19 pandemic on financial markets and the macro economy as well as certain displaced sectors of the economy, including those in which Ambac operates, including, but not limited to:
$500 billion for the Municipal Liquidity Facility;
$750 billion for the Primary Market Corporate Credit Facility and Secondary Market Corporate Credit Facility; and
The Money Market Mutual Fund Liquidity Facility.
In the UK, on March 20, 2020, the government announced the closure of all non-essential leisure, food and retail operations, including public houses. This closure remains in place with the date at which such operations may be permitted to reopen being uncertain. The UK Government also announced a number ofthese measures to mitigate the impact of these enforced closures including rebating employers 80% of staff salaries (up to a £2,500 per month per employee cap), tax deferrals, business loan schemes and property tax relief.are unwound.
While Ambac expects the foregoing measures to help mitigate economic damage and aid the functioning of the capital markets, Ambac's exposure to credit risk as a result of the economic fallout from the COIVD-19COVID-19 pandemic remains elevated, and we could still experience material losses that would adversely impact our future results of operations and financial condition.
Insured Portfolio:
Ambac establishedThe U.S. economy continues to recover from COVID-19 pandemic, aided by rapid vaccine diffusion, increased fiscal stimulus, and a setcontinued reopening of base case assumptions that includes a deep recessionthe economy. After contracting in 2020, the U.S. economy is projected to grow strongly in 2021, exceeding 2019 levels of economic output during the first halfcourse of the year. Unemployment has recovered 80% from the highs of about 15% in April 2020, with a modest recovery inbut still remains elevated at about 6% relative to pre-pandemic levels of about 3.5%.

However, the ultimate impact of ARPA and federal stimulus through the CARES Acteconomic recovery in general on the Ambac insured portfolio remains to be seen, as it will not benefit all insured exposures equally and other programs will help moderate the depth of the recession and therefore the impact on Ambac's insured portfolio.may not benefit certain exposures at all.
As part of thea detailed analysis of the insured portfolio, we have identified certain Public Finance sectors that are most susceptible to potential claims or impairments as a result of a prolonged recession caused by COVID-19.or uneven recovery from the COVID-19 pandemic. Our near-term concerns are concentrated on exposures substantially reliant on narrow, economically sensitive revenue streams. The ability of issuers of these obligations to pay is expected to be impairedstressed although several issuers expressed a willingness to use their balance sheets to support their obligations and avoid defaults in the near-term.

At this time, there are still significant uncertainties surrounding the ultimate number of claims and scope of damage resulting from this pandemic.

COVID-19
The COVID-19 pandemic had a significant impact on Commonwealth of Puerto Rico much as it did in the 50 U.S. states and other U.S. territories. However, the Puerto Rico economy is currently in recovery with vaccination rates increasing and infection rates declining. Hotel occupancy in the first week of April 2021 reached 84%, which is the highest level since March 2019. Overall, the Commonwealth's general fund revenues in the eight-month period ending February 2021 were up 1.8% year-on-year to $6.75 billion from $6.63 billion and were $1.18 billion higher than the budgeted amount for the period. As reported in the April 23, 2021, Commonwealth Fiscal Plan, Puerto Rico is also expected to benefit from about $43.5 billion in COVID-19-related federal funds from the initial CARES related measures in 2020 through the recently enacted ARPA.
It is unclear if the recovery will hold, what this implies for the Commonwealth’s ability and willingness to pay debt service, and what if any lasting effects COVID-19 will have on the economic and financial profile of Puerto Rico.
Over the longer-term, Puerto Rico's recovery profile will be impacted by a wide range of factors as well as financial considerations including, but not limited to:

Commonwealth Fiscal PlansPlan
On May 9, 2019,April 23, 2021, the Oversight Board certified its own version of a new Commonwealth Fiscal Plan. In this current Commonwealth Fiscal Plan, the annual Commonwealth budget surpluses are lower in the short term but larger in the long term than the previous plan because of a longer than previously expected roll-out of federal disaster spending. The surplus through fiscal 2024 is just under $14 billion, whereas the previous plan was almost $18 billion. The current plan projects a 30-year surplus of $19.7 billion, but $5.4 billion of that money may not be available to the Commonwealth because it is being generated by public corporations.
On May 3, 2020, the Government of Puerto Rico submitted a draft revised Commonwealth Fiscal Plan to the Oversight Board. The Government’s draft revisedThis most recent Commonwealth Fiscal Plan purports to incorporate the impact of the $120 billion of federal recovery money stemming from the 2017 hurricanes, 2019-2020 earthquakes, and COVID-19 onpandemic, including the Commonwealth economy, and projects diminished growth, surplus, and debt capacity as compared to previous Fiscal Plans.recently enacted American Rescue Plan Act or ARPA. The draft revisedcurrent certified Commonwealth Fiscal Plan also states thatprojects a surplus of $15.2 billion in years 2022-2035, with deficits beginning in 2036, whereas as May 2020's COVID-19 affected certified Commonwealth Fiscal Plan projected a surplus of $5.8 billion over a similar period. Debt sustainability analysis in the Oversight Board’snew plan suggests a modest increase to $5.6 billion from $5.0 billion (based upon mid-point of ranges shown in the plan).

III proceeding. However, as was also the case with previous versions of the COVID-19 pandemic. The Oversight Board has not certified the Government of Puerto Rico’s draft revised Fiscal Plan, and may modify the draft revised Commonwealth Fiscal Plan, significantly before certifying a revised fiscal plan. The Oversight Board has stated that it hopes to certify a revisedthe current version of the Commonwealth Fiscal Plan bylacks a high degree of transparency regarding the end of May 2020. The Oversight Board’s certified Fiscal Plan could be significantly different than either the current Commonwealth Fiscal Plan or the Government of Puerto Rico’s draft revised Commonwealth Fiscal Plan.
On June 5, 2019, the Oversight Board certified its own version of the Fiscal Plan for the Puerto Rico Highwaysunderlying data, assumptions and Transportation Authority ("PRHTA"). Without considering PRHTA Fiscal Plan measures, the PRHTA’s total financial surplus over the six-year plan period is projected to be $31 million. However, after taking into account the measures set forth in the PRHTA Fiscal Plan, the Oversight Board states that the cumulative surplus over that six-year period would grow to $493 million.
It is unknown ifrationales supporting those assumptions, making reconciliation and when a PRHTA Plan of Adjustment will be filed by the Oversight Board or confirmed by the court overseeing the Title III proceedings of PRHTA.

Commonwealth Plan of Adjustment
On February 9, 2020,23, 2021, the Oversight Board, announced it reached an agreement in principle ("Plan Support Agreement") with certain creditors supporting the restructuringas representative of the Commonwealth's General Obligation and PBA debt, and intended to file an amended plan of adjustment ("Amended POA") reflecting the terms of this agreement.
On February 28, 2020, the Oversight Board filed an amended disclosure statement and Amended POA to restructure $35 billion of debt and other claims against the Commonwealth of Puerto Rico, PBA, and ERS, as well as more than $50 billion in pension liabilities. Thethe Employee Retirement System of the Government of the Commonwealth of Puerto Rico publicly disclosed the Second Amended POA would reduce Commonwealth debtPlan Support Agreement ("Second Amended PSA"). Assured Guaranty Corp. and other claims from $35 billionAssured Guaranty Municipal Corp. ("Assured") and National Public Finance Guarantee Corporation ("National") conditionally agreed to less than $11 billion, a 70% cut. Thethe Second Amended POA would reduce the Commonwealth’s annual debt service by 56%. Treatment for pension claims is the same as contained in the Initial POA, which is a reduction in pension payments by as much as 8.5% for retirees who currently receive at least $1,200 a month, such that 60% of retirees would not face any cuts, and the establishment of a pension reserve fund to help support retirement payments in future years.
PSA. On March 21, 2020,February 23, 2021, the Oversight Board announced that in lightthe Second Amended PSA had the support of 70% of all GO and PBA bonds claims, including the conditional support of Assured and National.
Assured and National originally had until March 31, 2021, to terminate their agreement to the Second Amended PSA, however, that date was extended a number of times, including most recently to May 5, 2021, due to ongoing negotiations between the Oversight Board and the two monolines regarding the treatment of certain revenue bond claims. The Government of the developing COVID-19 crisis it was shifting its effortsCommonwealth of Puerto Rico and Ambac Assurance are not currently parties to assistingthe second Amended PSA.
On March 8, 2021, the Oversight Board filed with the Title III court a Second Amended Title III Joint Plan of Adjustment of the Commonwealth ("Second Amended POA") that purports to restructure approximately $35 billion of debt (including GO and PBA bonds) and other claims against the government of Puerto Rico and certain entities and $50 billion in preparingpension obligations. The Second Amended POA includes the terms of the settlement relating to face the crisis. As part of this shift,GO bonds embodied in the Second Amended PSA, dated February 22, 2021.
On April 12, 2021, the Oversight Board presentedannounced that it had reached an agreement in principle with Assured and National regarding the PRHTA claims, the Convention Center District Authority ("CCDA") claims and the Commonwealth treatment of deficiency claims. In conjunction with this agreement in principle, the two monolines were granted further extensions to terminate their conditional support for the Second Amended PSA while the agreement in principle was further negotiated and documented.
In general, the Second Amended PSA provides for lower Commonwealth debt service payments per annum relative to the Plan Support Agreement signed in February 2020 (Amended PSA), extends the tenor of new recovery bonds, increases the amount of cash distributed to creditors, and provides additional consideration in the form of a motion in courtcontingent value instrument ("CVI"). This CVI is intended to adjourn considerationprovide creditors with additional

More specifically, fixed consideration as part of the Oversight Board filed a status report before the court indicating that it was not yet prepared to propose a revised timeline for hearings related to theSecond Amended POA orincludes a combination of cash, new GO current interest bonds as well as new GO capital appreciation bonds. Recovery derived from fixed consideration is estimated to vary between approximately 67% and 77% (as of petition date) for GO creditors, and between approximately 75% and 80% (as of petition date) for PBA creditors.
Under the disclosure statement related thereto. The Oversight Board is scheduled to file a status report on July 15, 2020, at which time the Oversight Board has indicated it will propose a timelineMay 5, 2021, PRHTA/CCDA PSA, consideration for revenue bond creditors such hearings.
In a radio interview on March 24, 2020, Oversight Board Chairman Jose Carrion stated that the COVID-19 pandemic has had a material impact on Commonwealth finances and that the Oversight Board is reviewing the Commonwealth Plan of Adjustment, including the size of the proposed reduction in Commonwealth debt and proposed cuts to pensions. Carrion went on to say he does not see the Commonwealth Plan of Adjustment moving forward as currently structured. It is unclear at this time how much timelines for the POA process may shift as a result of the COVID-19 crisis.
The Amended POA, as is, disproportionately disadvantages claims against the Commonwealth related to certain revenue bonds issued by Puerto Rico instrumentalities, including those insured by Ambac Assurance. The Amended POA provides for estimated recovery of 3.9% on claims against the Commonwealth related to PRHTA, bonds,CCDA, or Puerto Rico Infrastructure Financing Authority (PRIFA)("PRIFA") Special Tax Revenue (Rum Tax)("Rum Tax") bonds, and Puerto Rico Convention Center District Authority (PRCCDA) bonds. It is unknown if and howon account of their deficiency claims ("Clawback claims") against the Amended POA may be modified or what the final adjustments will beCommonwealth, consists of CVI tied to the revenuesoutperformance of the SUT against the certified 2020 Commonwealth Fiscal Plan projections. For years one through 30, a portion of the CVI consideration to be made available to the Puerto Rico instrumentalities addressedrevenue bond creditors reflects a 40% share of cumulative outperformance, starting July 1, 2021, subject to a combined 95% outperformance limit with the subsequently mentioned amounts subject to a waterfall. The other portion of the CVI consideration receives, on an annual basis, the lesser of (i) 50% of cumulative outperformance, less payments previously made, and (ii) 75% of annual outperformance, subject to a waterfall with the GO creditors receiving the first $100 of annual payments in years one through 22 and the Clawback creditors receiving the next $11.1 and any amount thereafter split pro rata with 90% going to GO creditors and 10% going to Clawback creditors. For years 23 through 30, subject to the limits in (i) and (ii) above, 100% of the outperformance goes to the Clawback creditors. Overall, CVI recoveries are subject to a lifetime cap of 75% of deficiency amounts. The value of the Clawback CVI is highly uncertain given the contingent, outperformance-driven structure of the instrument coupled with the likely back-ended potential cash flows (years 23 through 30). Changes in our assumed values of the Clawback CVI will cause a change in our reserves.
In addition, under the PRHTA/CCDA PSA, the PRHTA creditors would receive 'hard currency' in the form of new PRHTA bonds totaling $1,245 with maturities of up to 40 years and an average interest rate of 5.0%. Of the $1,245 in new bonds, approximately $646.4 would be allocated to holders of PRHTA '68 bonds and approximately $598.6 would be allocated to holders of PRHTA '98 bonds. PRHTA creditors would also share $389 of cash proceeds, including a $264 interim distribution, payable at the effective date of the Commonwealth plan of adjustment, and $125 of restriction fees and consummation costs, payable at the effective date of the PRHTA plan. Of the $264 interim cash distribution, $184.8 would be allocated to holders of PRHTA ’68 bonds and $79.2 would be allocated to holders of PRHTA ’98 bonds. Claim recovery expectations for PRHTA creditors under the PRHTA/CCDA PSA are uncertain and subject to interpretation due to the current lack of clarity related to the aforementioned uncertainty related to the value of the Clawback CVI.
Under the May 5, 2021 PRHTA/CCDA PSA, CCDA creditors would also receive $112 of cash, inclusive of up to $15 related to restriction fees and consummation costs payable at the effective

PRIFA was not part of the May 5, 2021 PRHTA/CCDA PSA and, consequently, there are no additional recoveries provided for in the agreement in principle or Second Amended POA orfor PRIFA beyond the recoveries on claims againstproposed treatment of deficiency claims.
While we expect the Commonwealth by creditors of those instrumentalities, including Ambac and Ambac-insured bondholders.Second Amended POA to be modified to reflect the settlements agreed in the PRHTA/CCDA PSA, it is unclear if the Second Amended POA will be otherwise modified further. However, if the Second Amended POA were confirmed in its current form, Ambac's financial condition would suffer a material negative impact. Refer to Note 6.

Ambac Title III Litigation Update
AAC is party to a number of litigations related to its Puerto Rico exposures, and actively participates in the Commonwealth’s Title III proceedings before the United States District Court for the District of Puerto Rico.
On January 16, 2020, AAC, together with other monoline insurers, filed motions which sought to lift the automatic stay and allow Ambac and others to enforce their rights related to PRHTA, CCDA and PRIFA in an alternative forum. Through orders issued on July 2 and September 9, 2020, Judge Swain largely denied the motions, while holding in abeyance further proceedings in the CCDA motion relating to a particular account over which it is undisputed the monolines have a lien. AAC and the other movants appealed the PRHTA and PRIFA decisions. On March 3, 2021, the First Circuit affirmed the District Court’s opinions denying the motions to lift the stay with respect to bonds issued by HTA and bonds issued by PRIFA on procedural grounds, leaving the question of whether the monolines have a lien with respect to such bonds to be resolved in the pending summary judgment proceedings before the District Court.
On January 16, 2020 the Oversight Board filed four adversary proceeding complaints against AAC, and other monoline insurers, seeking to disallow their proofs of claim against the Commonwealth as they relate to HTA, CCDA, and PRIFA bonds. On April 28, 2020, the Oversight Board filed partial motions for summary judgment. Briefing has concluded on those motions for summary judgment and oral argument was held on September 23, 2020. On January 20, 2021, the District Court granted defendants’ request for deferral of the adjudication of the summary judgment motion until defendants have the opportunity to conduct certain discovery. Discovery is ongoing.
AAC, along with other monoline insurers, filed a motion seeking appointment as trustees under Section 926 of the Bankruptcy Code to pursue certain avoidance actions on behalf of HTA against the Commonwealth of Puerto Rico. The motion attached a proposed complaint detailing the avoidance claims that movants would pursue. On August 11, 2020 the Court denied the motion and AAC and the other movants have appealed that denial. Movants' opening brief before the First Circuit was filed on
February 17, 2021; briefing is expected to conclude on May 24, 2021.
If AAC is unsuccessful in any of these proceedings, Ambac’s financial condition, including liquidity, loss reserves and capital resources may suffer a material negative impact.
Refer to "Financial Guarantees in Force" in Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Ambac’s Annual Report on Form 10-K for the year ended December 31, 2020 and Note 12.

Mediation
The status, timing and subject of any subsequentpast or future mediation discussion has not yet been publicly disclosed. The timeline for resolution of Puerto Rico's debt restructuring process is uncertain.
The Oversight Board disclosed, in a status report filed with the Title III court in September 2020, that it has resumed formal discussions with creditors with the guidance of the mediation team led by Judge Houser. Prior to the talks with creditors, the Oversight Board held discussions with AAFAF concerning the terms of a Commonwealth Plan of Adjustment and what, if any, modifications or amendments needed to be proposed.
On February 10, 2021, the Oversight Board disclosed that mediation resulted in an agreement in principle with certain GO and PBA bondholders. The Second Amended PSA was publicly disclosed on February 23, 2021.
On April 12, 2021, the Oversight board disclosed that mediation resulted in an agreement in principle with Assured and National regarding the PRHTA claims, the CCDA claims and the Commonwealth treatment of deficiency claims. On May 5, 2021, the Oversight Board published the PRHTA/CCDA PSA finalizing this agreement in principle.
No assurances can be given that debt restructuring negotiations will be successfully concluded, that the Commonwealth, Oversight Board and creditor parties will reach definitive agreements on debt restructurings, that any additional negotiated transaction, debt restructuring, definitive agreement or Plan of Adjustment will be approved by the court and completed, or that any transaction or Plan of Adjustment will not have ana materially adverse impact on Ambac's financial conditionscondition or results.results of operations.
Federal Aid
The Commonwealth of Puerto Rico is projected to benefit from over $48 billion of federal disaster aid for infrastructure improvement initiatives or recovery efforts, as a result of the damage cause by hurricanes Irma and Maria as well as the earthquakes that began in late December 2019. To date, only about $15 billion has been disbursed. More than $20 billion of Community Development Block Grants (CDBG) was appropriated by Congress for Puerto Rico for reconstruction following Hurricane Maria, but very little has yet been drawn down. The Department of Housing and Urban Development (HUD), which administers the CDBG program, has approved release of a second tranche of CDBG funds totaling $8.2 billion, which brings the total amount available for drawdown to nearly $10 billion (an additional roughly $10 billion has not yet been approved by HUD for release).
In order to ensure federal taxpayer dollars are spent effectively and efficiently, HUD has conditioned release of the $8.2 billion on various requirements that Puerto Rico must meet. Governor Wanda Vasquez has agreed to these requirements, which includes a prohibition on any of the funds from being used to rebuild the electric grid until (and unless) HUD publishes additional requirements on such spending; overturns an executive order establishing a $15 minimum wage for government construction projects using CDBG; requires greater Puerto Rico to provide greater transparency and implement enhanced financial controls; and requires CDFBG spending plans to be submitted to the Oversight Board for determination that they are in accordance with its certified budgets and fiscal plans. Consequently, it is anticipated that drawdown of funds will begin soon. HUD has also appointed a federal monitor to oversee use of CDBG funds.
The Oversight Board states, on their COVID-19 webpage, that Puerto Rico residents, businesses, and government appear to be eligible for approximately $10 billion in federal aid under the CARES Act. On April 22, 2020, the Government of Puerto Rico announced that they had received $2.2 billion in direct aid provided by the CARES Act for the territories, for necessary COVID-19 related expenditures and costs not previously budgeted for. In addition, all U.S. citizens and residents (including in Puerto Rico) will receive one-time cash payments of $1,200 for single taxpayers, $2,400 for married filers and $500 for each child, with payments gradually phasing out for individuals who earn between $75,000 and $99,000 per year (or $150,000 and $198,000 for married filers).
The Government of Puerto Rico's initial estimate is that eligible residents of Puerto Rico will receive a total aggregate amount of $1.5 billion. Separately, Commonwealth small businesses have received an estimated $757 million in loans under the first portion of the Payroll Protection Fund (PPP) under the CARES Act. Puerto Ricans who are unemployed will also benefit from federal funding in the CARES Act that increases unemployment insurance benefits significantly for several months.
The full extent of federal government support to Puerto Rico is still uncertain as existing federal stimulus has not been fully implemented and additional measures are likelyestimated to be enacted. $120 billion per the April 23, 2021, certified Commonwealth Fiscal Plan and stretch from FY 2018 to FY 2035. The federal government support includes FEMA, HUD and other disaster relief funds stemming from the 2017 hurricanes and 2019-2020 earthquakes and includes about $43 billion of support related to the COVID-19 pandemic, including funding form the recently enacted ARPA.
While the previously allocated federal disaster relief funds Medicaid money, and the more recent COVID-19 crisis related funds are all expected to support economic recovery and growth and in Puerto Rico, there

can be no assurances as to the certainty, timing, usage, efficacy or magnitude of benefits to creditor outcomes related to disaster aid and ensuing economic growth, if any.
Summary
Ambac has considered these developments and other factors in evaluating its Puerto Rico loss reserves. During the quarterthree months ended March 31, 2020,2021, Ambac had incurred losses associated with its Domestic Public Finance insured portfolio of $178 million,$9, which was impacted by lower discount rates as well as the continued uncertainty and volatility of the situation in Puerto Rico, including the potential impact of the COVID-19 crisis on the CommonwealthSecond Amended PSA and the developing potential impact of the COVID-19 crisis on other sectors in the Domestic Public Finance insured portfolio.PRHTA/CCDA PSA. 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 and the overall uncertain impact of the COVID-19 crisis on the Commonwealth and the Domestic Public Finance Insured Portfolio in general. Such additional losses may have a material adverse effect on Ambac’s results of operations and financial condition.

The decreasenet decline in below investment grade exposures is primarily due to the commutationde-risking of certain general obligation exposures and the impact of foreign exchange rates resulting from the strengthening of the US Dollar, partially offset by the addition of certain lease and tax-baked exposures and an international structured finance exposure driven by the COVID-19 pandemic. Despite the decrease in belowadversely classified stadium transaction.
Below investment grade exposures, such exposures could increase as a relative proportion of the guarantee portfolio given that stressed borrowers generally have less ability to prepay or refinance their debt. Accordingly, due to these and other factors, it is not unreasonable to expect the proportion of below investment grade exposure in the guarantee portfolio to continue to increase in the future.
RESULTS OF OPERATIONS
Net loss attributable to common stockholders for the three months ended March 31, 2020, was $280 million compared to a net loss attributable to common stockholders of $43 million for the three months ended March 31, 2019. The decrease was primarily driven by: (i) net losses on investments, (ii) larger net losses on derivative contracts, (iii) lower net premiums earned, (iv) lower income on variable interest entities and (v) higher loss and loss expenses, partially offset by lower insurance intangible amortization.

Ambac's results of operations and financial position have been adversely impacted by the COVID-19 pandemic's effect on the global economy and financial markets. Significant interest rate declines during the first quarter of 2020 drovecontributed materially to a net increase toin loss reserves and losses on interest rate derivative contracts. Credit driven losses were also recognized in both lossthe three months ended March 31, 2020, within losses incurred (primarily from public finance insurance policies) and losses infrom counterparty credit adjustments on derivative asset valuations. Financial market disruptions arewere reflected through lower valuations of certain fixed incomematurity securities (recorded through other comprehensive income) and the majority of other investments (recorded through net investment income (loss))income). During the remaining quarters of 2020 and into 2021, credit spreads recovered (favorably impacting counterparty credit adjustments on derivative assets and valuations of investment securities). The scope, duration and magnitude of the direct and indirect effects of COVID-19 are evolving rapidly and in ways that are difficult or impossible to anticipate. As a result, it is possible that Ambac's results of operations and financial condition may be further adversely affected by the evolving affects of the COVID-19 pandemic. For additional information on the risks posed by COVID-19, refer to “Part II, Item 1A-Risk Factors” in this Quarterly Report on Form 10-Q.
During 2019, Ambac executed on a number of restructuring / commutation transactions that had significant impacts to the consolidated results of operations. As described further below, the completion of the these transactions, including the related changes to invested assets, loss reserves and debt of the Company, had a significant impact on the comparability of the results of operation for the three months ended March 31, 2020 and 2019. The most significant transactions, which are more fully discussed in "Financial Guarantees in Force" in Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Ambac’s Annual Report on Form 10-K for the year ended December 31, 2019 were:
Puerto Rico COFINA Plan of Adjustment ("POA").On February 12, 2019, the POA, including certain related commutation transactions, and subsequent distributions, became effective, resulting in a significant reduction of Ambac Assurance's insured net par exposure to COFINA. Pursuant to the COFINA POA, approximately 75% of holders of Ambac Assurance-insured senior COFINA bonds (including Ambac) elected to commute their insurance policy.
Ballantyne Re plc ("Ballantyne") Restructuring. On April 25, 2019, Ballantyne commenced, under Irish law, a restructuring transaction ("Restructuring") in respect of its obligations, including obligations that were guaranteed by Ambac UK. The arrangement was approved on June 17, 2019. With the successful implementation of the Restructuring, Ambac UK has ceased to have any exposure with respect to the obligations of Ballantyne.
The following paragraphs describe the consolidated results of operations of Ambac and its subsidiaries for the three months ended March 31, 20202021 and 2019,2020, respectively.
Net Premiums Earned. Net premiums earned primarily represent the amortization into income of insurance premiums. We present accelerated premiums, which result from calls and other accelerations of insured obligations separate from normal net premiums earned. When an insured bond has been retired, any remaining unearned premium revenue ("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
| Ambac Financial Group, Inc. 502021 First Quarter FORM 10-Q |



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.
Net premiums earned decreased $18 millionincreased $4 for the three months ended March 31, 2020,2021, compared to the same periodperiods in the prior year. Normal net premiums earned and accelerated premiums are reconciled to total net premiums earned in the table below. The following table provides a breakdown of normal premiums earned by market:

The decreaseincrease in normal premiums earned infor the three months ended March 31, 2020,2021, is primarily attributabledue to (i)changes in allowances for credit losses on premium receivables, partially offset by the continued runoff of the insured portfolio in all markets and (ii) changes to allowance for credit losses on premiums receivables.markets. Ambac adopted ASU 2016-13, Measurement of Credit Losses on Financial Instruments ("CECL"), on January 1, 2020, and will assessassesses the allowance for credit losses on premium receivables on a quarterly basis. Prior to adoption of ASU 2016-13, Ambac assessed collectability of premium receivables in accordance with ASC 944 and recorded an allowance for uncollectible premiums. The three months ended March 31, 2020,2021, includes an increasea decrease in the allowance for credit losses since adoption of CECL of $2 million$4 as comparedcompared to an increase of less than $1 million$2 for the three months ended March 31, 2019.2020.

The decrease in accelerated earnings infor the three months ended March 31, 2020, as compared to2021, were also impacted by reinsurance cessions in the three months ended March 31, 2019, is primarily related to the COFINA restructuring that occurred in February 2019.first quarter of 2021.
Net Investment Income (Loss).Income. Net investment income (loss) primarily consists of interest and net discount accretion on fixed incomematurity securities classified as available-for-sale and net gains (losses) on pooled investment funds which include changes in fair value of the funds' net assets. Fixed incomematurity securities include investments in Ambac-insured securities that are made opportunistically based on their risk/reward and asset-liability management characteristics. As described further below, investment income from holdings of Ambac-insured securities (including Secured Notes issued by Ambac LSNI, LLC) for the periods presented have primarily been affected by restructuring transactions involving Puerto Rico and Ballantyne bonds. Investments in pooled investment funds and certain other investments are either classified as trading securities with changes in fair value recognized in earnings or are reported under the equity method. These funds and other investments are reported in Other investments on the Unaudited Consolidated Balance Sheets, and consistwhich consists primarily of pooled fund investments in diversified asset classes.

The decrease wassame periods in the prior year. As described further below, the variances were primarily driven by unrealized losses onpricing volatility within fund investments resulting from the impact of the COVID-19 pandemic on financial markets a smaller allocation to higher yieldingand re-allocation of the investment portfolio during 2020 toward pooled funds and Ambac-insured bonds from investment grade corporate bonds, commercial mortgage backed securities and a lower overall invested asset base.certain CLOs.
Other investments income (loss) increased $79 for the three months ended March 31, 2021, compared to the same period in the prior year, reflecting strong performance for the three months ended March 31, 2021, particularly in hedge funds and equity funds. Losses on Other investments reported for the three months ended March 31, 2020, were in hedge and other fund investments focusing on asset-backed securities, equities, high-yield, leveraged loans and private credit. These losses were primarily driven by adverse changes in fair values, as opposed torather than realized losses, stemming from an increase in risk premiums (including(particularly credit spreads) as a consequence of the initial economic and financial market impact of the COVID-19 pandemic. These investment funds have begun to recover in value during the second quarter of 2020. Ambac currently views these unrealized losses as temporary
subject to any subsequent decisions to monetize certain investments in connection with changes in investment strategy, market conditions, and/or other circumstances. Other investment incomeIncome from Ambac-insured securities was lower for the three months ended March 31, 2019, was driven by gains on equity, high-yield and loan funds, partially offset by losses on an insurance-linked security fund.
Income from Ambac-insured securities was lower2021, as compared to the three months ended March 31, 2020, due to the effects of 2019 de-risking transactions and ongoing redemptions of Secured Notes issued by Ambac LSNI, LLC. Ambac's holdings of insured COFINALLC and Ballantyne bonds were settled in connection with the February 2019 COFINA commutation and June 2019 Ballantyne Restructuring, respectively, accounting for the majority of the decrease in income from Ambac-insured securities. Additionally, income from Secured Notes is down as a result of early redemptions as well as lower LIBOR indexed coupon rates, effectivepartially offset by a higher allocation to Ambac-insured RMBS and Puerto Rico bonds.
Net investment income from available-for-sales securities other than Ambac-insured securities decreased as a result of a lower asset base and average yield for this portion of the portfolio. The lower asset base resulted primarily from re-allocation of the portfolio in 2020 toward pooled funds and Ambac-insured bonds from investment grade corporate and certain asset-backed securities. Additionally, cash has been used to fund operations, early debt redemptions, and Ambac's acquisition of Xchange. Lower yields in the three months ended March 31, 2020 as2021, compared to the three months ended March 31, 2019.
Net investment income (loss) from available-for-sales2020, reflect the higher rated securities other than Ambac-insured securities decreased primarily as a result ofpurchased during the favorable impact2020 portfolio re-allocation, lower relative yields on income fornew investments and near-zero short term rates prevailing during the three months ended March 31, 2019, of high yielding uninsured COFINA bonds received under the POA. All of these uninsured COFINA bonds were sold from Ambac's non-VIE investment portfolio by December 31, 2019. Additionally, income from available-for-sale securities for the three months ended March 31, 2020, was down due to a smaller asset base and generally declining reinvestment rates since first quarter 2019.of 2021.

Impairments are reported through earnings if management intends to sell securities or it is more likely than not that the Company will be required to sell before recovery of amortized cost. Credit impairments are recorded in earnings only to the extent management does not intend to sell, and it is not more likely than not that the Company will be required to sell the securities, before recovery of their amortized cost. When credit impairments are recorded, any non-credit related impairment amounts on the securities are recorded in other comprehensive income.

Intent / requirement to sell impairments for the three month periods ended March 31, 2020, and 2019, related solely to management's intent to sell securities.
Net Gains (Losses) on Derivative Contracts. Net gains (losses) on derivative contracts include results from the Company's interest rate derivatives portfolio and its runoff credit derivatives portfolio. The interest rate derivatives portfolio is positioned to benefit from rising rates as a partial economic hedge against interest rate exposure in the financial guarantee and investment portfolios. As forward rates and interest rate exposures elsewhere in the company have declined over the course of 2019 into the first quarter 2020, the economic hedge position has been reduced. Net gains (losses) on interest rate derivatives generally reflect mark-to-market gains (losses) in the portfolio caused by increases (declines) in forward interest rates during the periods, the carrying cost of the portfolio, and the impact of counterparty credit adjustments as discussed below. Results from credit derivatives were not significant to the periods presented.
Net gains (losses) on interest rate derivatives for the three months ended March 31, 2020,2021, were ($68) million,$25 compared to ($17) million68) for the three months ended March 31, 2019.2020. The net gain for the three months ended March 31, 2021, reflects changes in fair value from rising forward interest rates and lower counterparty credit adjustments on certain derivative assets. The net loss for the three months ended March 31, 2020, reflects significant declines in forward interest rates, triggered by the COVID-19 pandemic, and losses from the application of counterparty credit adjustments, described further below. The net losses for three months ended March 31, 2019, were driven by the impact of declines in forward interest rates during the period. Net carrying costs were not significant to the periods presented.
Counterparty credit adjustments are generally applicable for uncollateralized derivative assets that may not be offset by derivative liabilities under a master netting agreement. Inclusion of counterparty credit adjustments in the valuation of interest rate derivatives resulted in gains (losses) within Net gains (losses) on derivative contracts of $(30) million$9 for the three months ended March 31, 2020,2021, and $(1) million$(30) for the three months ended March 31, 2019. The2020. In addition to the impact of interest rates on the underlying derivative asset values, the changes in counterparty credit adjustments were driven by narrowing credit spreads in the three months ended March 31, 2021, compared to spread widening experienced in the first quarter of 2020 associated with the market disruption from the COVID-19 pandemic.
Other income (expense). Other income (expense) includes commission revenues of Xchange, various financial guarantee fees and foreign exchange gains/(losses) unrelated to investments or loss reserves. For the three months ended March 31, 2021, other income includes Xchange revenues of $7.
Net Realized Gains on Extinguishment of Debt.

Income (loss)(Loss) on Variable Interest Entities. Included within Income (loss) on variable interest entities are income statement amounts relating to VIEs, consolidated under the Consolidation Topic of the ASC as a result of Ambac's variable interest arising from financial guarantees written by Ambac's subsidiaries, including gains or losses attributable to consolidating or deconsolidating VIEs during the periods reported. Generally, the Company’s consolidated VIEs are entities for which Ambac has provided financial guarantees on all of or a portion of its assets or liabilities. In consolidation, assets and liabilities of the VIEs are initially reported at fair value and the related insurance assets and liabilities are eliminated. However, the amount of VIE net assets (liabilities) that remain in consolidation generally result from the net positive (negative) projected cash flows from (to) the VIEs which are attributable to Ambac’s insurance subsidiaries in the form of financial guarantee insurance premiums, fees and losses. In the case of VIEs with net negative projected cash flows, the net liability is generally to be funded by Ambac’s insurance subsidiaries through insurance claim payments. Differences
between the net carrying value of the insurance accounts under the Financial Services—Insurance Topic of the ASC and the carrying value of the consolidated VIE’s net assets or liabilities are recorded through income at the time of consolidation or deconsolidation.consolidation. Additionally, terminations or other changes to Ambac's financial guarantee insurance policies that impact projected cash flows between a consolidated VIE and Ambac could result in gains or losses, even if such policy changes do not result in deconsolidation of the VIE.
Income (loss) on variable interest entities was income of less than a million and income of $3 million for the three months ended March 31, 2021 and 2020, compared to income of $16 millionrespectively. Results for the three months ended March 31, 2019.2021, included realized gains of $1 on sales of assets from one VIE (the COFINA Trust) partially offset by the lower valuation of net assets on a VIE impacted by credit downgrades. Results for the three months ended March 31, 2020, were due primarily to realized gains of $8 million on sales of assets from the COFINA Trust partially offset by the lower valuation of net assets on anothera VIE drivenimpacted by the economic uncertainty caused by COVID-19. Results for the three months ended March 31, 2019, were driven by the $15 million gain on consolidation of the COFINA Trust.

Ambac records as a component of its loss reserve estimate subrogation recoveries related to securitized loans in RMBS transactions with respect to which Ambac AssuranceAAC is pursuing claims for breaches of representations and warranties. Ambac does not include potential recoveries attributed solely to fraudulent inducement claims in our litigations in our estimate of subrogation recoveries. Generally, the sponsor of an RMBS transaction provided representations and warranties with respect to the securitized loans, including representations with respect to the loan characteristics, the absence of borrower fraud in the underlying loan pools or other misconduct in the origination process and attesting to the compliance of loans with the prevailing underwriting policies. Ambac has recorded representation and warranty subrogation recoveries, net of reinsurance, of approximately $1,738$1,722 and $1,702$1,725 at March 31, 2020,2021, and December 31, 2019,2020, respectively. The increase in these recoveries was primarily driven by lower discount rates used to discount estimated cash flows. Refer to Note 2. Basis of Presentation and Significant Accounting Policies to the Consolidated Financial Statements included in Part II, Item 8 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019,2020, for more information regarding the estimation process for R&W subrogation recoveries.

Losses and loss expenses (benefit) for the three months ended March 31, 2021, were driven by higher projected losses in domestic public finance from adverse development related to Puerto Rico, partially offset by the positive impact of higher discount rates. The underlying assumptions impacting our reserves for Puerto Rico during the three months ended March 31, 2021, were within the range of assumptions underlying our probability weighted reserves as of December 31, 2020.
Losses and loss expenses (benefit) for the three months ended March 31, 2020, were driven by the following:
Higher projected losses in domestic public finance driven mostly by lower discount rates (primarily relating to Puerto Rico), and incurred losses related to transactions directly impacted by the economic impact from COVID-19; and
An increase in student loan losses as a result of lower discount rates and the impact from COVID-19; partially offset by,

Gross operating expenseexpenses increased $9 for the three months ended March 31, 2020, were $24 million, a decrease of $1 million from2021 compared to the same period in the prior year. The increase in operating expenses during the three months ended March 31, 2019. Operating2021, as compared to the three months ended March 31, 2020, was due to the following:
Higher compensation costs due to the inclusion of Xchange compensation costs for the first time since its acquisition, accelerated expense recognition for retirement eligible stock-based compensation awards and lower capitalization for internal software projects, partially offset by lower bonus expense recognized in the three months ended March 31, 2021.
Higher non-compensation costs primarily due to the inclusion of Xchange's commissions to sub-producers of $4, consulting and legal fees associated with the surplus note exchange transactions and a $1 UK Value Added Tax (VAT) refund which lowered expenses incurred relating to COVID-19 have been minimal for the three months ended March 31, 2020.
The decrease in operating expenses was due to the following:
Lower compensation costs primarily due to lower salaries resulting from continued right sizing of staffing levels during 2019, partially offset by higher incentive compensation costs related to final performance metrics impacting settlement of 2019 annual bonuses, and
Lower non-compensation costs primarily due to a $1 million UK Value Added Tax (VAT) refund recognized in the three months ended March 31, 2020.
Legal and consulting services provided for the benefit of OCI amounted to $0.5 million and $0.5 million during the three months ended March 31, 2020 and 2019, respectively.

Surplus note principal and interest payments require the approval of OCI. Since the issuance of the surplus notes in 2010, OCI has declined to approve regular payments of interest on surplus notes, although the OCI has permitted two exceptional payments in connection with (a) increasing the percentage of deferred policy payments of the Segregated Account of Ambac Assurance from 25% to 45% in 2014 and (b) a one-time payment of approximately six months of interest on the surplus notes (other than junior surplus notes) outstanding immediately after consummation of the Rehabilitation Exit Transactions in 2018. Ambac Assurance has not requested to pay interest on any junior surplus notes since their issuance.payments.
In April 2020,May 2021, OCI declined the request of Ambac AssuranceAAC to pay the principal amount of the surplus notes, plus all accrued and unpaid interest thereon, on the next scheduled maturitypayment date of June 7, 2020.2021. As a result, the scheduled payment date for interest, and the scheduled maturity date for payment of principal of the surplus notes, shall be extended until OCI grants approval to make the payment. Interest will accrue, compounded on each anniversary of the original scheduled payment date or scheduled maturity date, on any unpaid principal or interest through the actual date of payment, at 5.1% per annum. Holders of surplus notes will have no rights to enforce the payment of the principal of, or interest on, surplus notes in the absence of OCI approval to pay such amount. The interest on the outstanding surplus notes and junior surplus notes were accrued for and Ambac AssuranceAAC is accruing interest on the interest amounts following each scheduled payment date. Total accrued and unpaid interest for surplus notes and junior surplus notes outstanding to third parties were $312 million and $152 million, respectively,$516 at March 31, 2020.2021.
Provision for Income Taxes. The provision for income taxes for the three months ended March 31, 2020,2021, was $(7) million, a decrease$2, an increase of $9 million compared to the provision for income taxes reported for three months ended March 31, 2019.2020. The change for the three months ended March 31, 2020,2021, as compared to the prior yearthree months ended March 31, 2020, was primarily driven by state income tax related to the gains on the surplus note exchanges, whereas 2020 was attributable to Ambac UK, which had a taxable loss, related to investment losses on pooled funds, in 2020 as compared to taxable income in 2019.funds.
LIQUIDITY AND CAPITAL RESOURCES
($ in millions)
Ambac Financial Group, Inc. ("AFG") Liquidity. AFG's liquidity is primarily dependent on its cash, investments (excluding equity investments in subsidiaries), and net receivables totaling $482 million$274 as of March 31, 2020,2021, and secondarily on itsdividends and expense sharing and other arrangementspayments from its subsidiaries.
During the three months ended March 31, 2021, AFG further capitalized the Everspan Group with Ambac Assurance.a cash contribution to Everspan Indemnity Insurance Company of approximately $82.
Pursuant to the amended and restated tax sharing agreement among AFG, Ambac Assurance and certain affiliates (the "Amended TSA"), Ambac Assurance is required to make payments ("tolling payments") to AFG with respect to the utilization of net operating loss carry-forwards (“NOLs”). AFG has accrued $28 million of tolling payments based on NOLs used by Ambac Assurance in 2017. In May 2018, AFG executed a waiver under the intercompany tax sharing agreement pursuant to which Ambac Assurance was relieved of the requirement to make this payment by June 1, 2018.  AFG also agreed to defer the tolling payment for the use of
net operating losses by Ambac Assurance in 2017 until such time as OCI consents to the payment.
Under an inter-company cost allocation agreement, AFG is reimbursed by Ambac AssuranceAAC for a portion of certain operating costs and expenses and, if approved by OCI, entitled to an additional payment of up to $4 million per year to cover expenses not otherwise reimbursed. OCI approved thisThe $4 million reimbursement for 20192020 expenses which was approved (by OCI) and paid (by AAC) in March 2020.April 2021.
AFG's investments include securities directly and indirectly issued by and/or insured by Ambac Assurance,AAC, some of which are eliminated in consolidation. Securities issued and/or insured by Ambac AssuranceAAC are generally less liquid than investment grade and other traded investments.
AFG has not received dividends from any of its subsidiaries during the first quarter of 2021 or the full year of 2020.
It is highly unlikely that Ambac AssuranceAAC will be able to make dividend payments to AFG for the foreseeable future and therefore cash and investments,future. Therefore, payments under the intercompany cost allocation agreement and future tolling payments, if any, will be AFG’s principal sourcesources of liquidity from AAC in the near term.near-term. Refer to Part I, Item 1, “Insurance Regulatory Matters — Dividend Restrictions, Including Contractual Restrictions” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019,2020, and Note 8. Insurance Regulatory Restrictions to the Consolidated Financial Statements included in Part II, Item 8, in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019,2020, for more information on dividend payment restrictions.
Everspan does not have sufficient earned surplus at this time to pay ordinary dividends under the Arizona Insurance Laws. Payments from Everspan to AFG may include expense allocation payments and tax payments.
Xchange currently does not have any regulatory restrictions on its ability to pay dividends and AFG expects it to begin paying dividends beginning in the second quarter of 2021.
The principal uses of liquidity areinclude the payment of operating expenses, including costs to explore opportunities to grow and diversify Ambac; and the making of investments, includingwhich may include securities issued or insured by AAC or Ambac Assurance. Future uses of liquidity may includeUK and other less liquid investments; and the acquisition or capitalization of new businesses. Contingencies could cause material liquidity strains.
Ambac Assurance Liquidity. Ambac Assurance’sAAC’s liquidity is dependent on the balance of liquid investments and, over time, the net impact of sources and uses of funds. The principal sources of Ambac Assurance’sAAC’s liquidity are gross installment premiums on insurance policies; principal and interest payments from investments; sales of investments; proceeds from repayment of affiliate loans; and recoveries on claim payments, including from litigation and reinsurance recoveries. Termination of installment premium policies on an accelerated basis may adversely impact Ambac Assurance’sAAC’s liquidity.

Refer to "Financial Guarantees in Force" in this Management's Discussion and Analysis for further discussion of the potential impact of the COVID-19 pandemic on claim payments.
Interest and principal payments on surplus notes are subject to the approval of OCI, which has full discretion over payments regardless of the liquidity position of Ambac Assurance. Any such payment on surplus notes would require either payment or collateralization of a portion of the Tier 2 Notes under the terms of the Tier 2 Note indenture. See Note 13. Long-term Debt in the Notes to Consolidated Financial Statements, included in Part II, Item 8, in the Company's Annual Report on Form 10-K for the year ended December 31, 2019 for further discussion of the payment terms and conditions of the Tier 2 Notes. As discussed more fully in "Results of Operations" above in this Management's Discussion and Analysis OCI declined Ambac Assurance's request to pay the principal amount of the surplus notes, plus all accrued and unpaid interest thereon, on June 7, 2020.

As discussed more fully in "Results of Operations" above in this Management's Discussion and Analysis, OCI declined AAC's request to pay the principal amount of the surplus notes, plus all accrued and unpaid interest thereon, on June 7, 2021 and on each prior scheduled payment date.
AAC's intercompany loans are with Ambac Financial Services ("AFS"). AFS uses interest rate derivatives (primarily interest ratedrate swaps and US Treasury futures) as an economic hedge against the effects of rising interest rates elsewhere in the Company, including on Ambac Assurance’sAAC’s financial guarantee exposures. AFS's derivatives include interest rate swaps previously provided to asset-backed issuers and other entities in connection with their financings. Ambac AssuranceAAC loans cash and securities to AFS as needed to fund payments under these derivative contracts, collateral posting requirements and operating expenses. Intercompany loans are governed by an established lending agreement with defined borrowing limits that has received non-disapproval from OCI.
Ambac AssuranceAAC manages its liquidity risk by maintaining comprehensive analyses of projected cash flows and maintaining specified levels of cash and short-term investments at all times.
Ambac AssuranceAAC is limited in its ability to pay dividends pursuant to the terms of its Auction Market Preferred Shares (“AMPS”), which state that dividends may not be paid on the common stock of Ambac AssuranceAAC unless all accrued and unpaid dividends on the AMPS for the then current dividend period have been paid, provided that dividends on the common stock may be made at all times for the purpose of, and only in such amounts as are necessary for enabling AFG (i) to service its indebtedness for borrowed money as such payments become due or (ii) to pay its operating expenses. If dividends are paid on the common stock for such purposes, dividends on the AMPS become cumulative until the date that all accumulated and unpaid dividends have been paid on the AMPS. Ambac AssuranceAAC has not paid dividends on the AMPS since 2010. Ambac AssuranceAAC is also subject to additional restrictions on the payment of dividends pursuant to certain
contractual and regulatory restrictions. Refer to Part I, Item 1, “Insurance Regulatory Matters - Dividend Restrictions, Including Contractual Restrictions” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019,2020, and Note 8.9. Insurance Regulatory Restrictions to the Consolidated Financial Statements included in Part II, Item 8, in the Company’s Annual
Report on Form 10-K for the year ended December 31, 2019,2020, for more information on dividend payment restrictions.
Our ability to realize RMBS representation and warranty ("R&W") subrogation recoveries is subject to significant uncertainty, including risks inherent in litigation;litigation, including adverse rulings or decisions in our cases or in litigations to which AAC is not a party that set precedents or resolve questions of law that impact our own claims; collectability of such amounts from counterparties (and/or their respective parents and affiliates); timing of receipt of any such recoveries, including uncertainty due to delays in court proceedings as a result of the COVID-19 pandemic; intervention by the OCI, which could impede our ability to take actions required to realize such recoveries; and uncertainty inherent in the assumptions used in estimating the amount of such recoveries. The amount of these subrogation recoveries is significant and if we are unable to recover any amounts or recover materially less than our estimated recoveries, our future available liquidity to pay claims, debt service and meet our other obligations would be reduced materially. See Part I, Item 1A. Risk Factors in the Company's Annual Report on Form 10-K for the year ended December 31, 20192020, for more information about risks relating to our RMBS R&W subrogation recoveries.

Financing Activities
Financing activities for the three months ended March 31, 2021, include paydowns of the Ambac Note of $16 and paydowns / maturities of VIE debt obligations of $48.
Financing activities for the three months ended March 31, 2020, include paydowns of the Ambac Note of $77 million and paydowns / maturities of VIE debt obligations of $66 million.
Financing activities for the three months ended March 31, 2019, include proceeds $3 million from Ambac's issuance of 201 shares of AMPS, paydowns of the Ambac Note of $13 million and paydowns / maturities of VIE debt obligations of $63 million.$66.
Collateral
AFS hedges a portion of the interest rate risk in the financial guarantee and investment portfolio, along with legacy customer interest rate swaps, with standardized derivative contracts, including financial futures contracts, which contain collateral or margin requirements. Under these hedge agreements, AFS is required to post collateral or margin to its counterparties and futures commission merchants to cover unrealized losses. In addition, AFS is required to post collateral or margin in excess of the amounts needed to cover unrealized losses. All AFS derivative contracts containing ratings-based downgrade triggers that could result in collateral or margin posting or a termination have been triggered. If terminations were to occur, AFS would be required to make termination payments but would also receive a return of collateral or margin in the form of cash or U.S. Treasury obligations with market values equal to or in excess of market values of the swaps and futures contracts. AFS may look to re-establish hedge positions that are terminated early, resulting in additional collateral or margin obligations. The amount of additional collateral or margin posted on derivatives contracts will depend on several variables including the degree to which counterparties exercise their termination rights (or agreements terminate automatically) and the terms on which hedges can be replaced. All collateral and margin obligations are currently met. Collateral and margin posted by AFS totaled a net amount of $165 million$124 (cash and securities collateral of $80 million$4 and $85 million,$120, respectively), including independent amounts, under these contracts at March 31, 2020.2021.
Ambac Credit Products (“ACP”) is not required to post collateral under any of its outstanding credit derivative contracts.

This decrease was primarily due to a Total Comprehensive Loss during 2020. The Comprehensive Loss was primarily driven by the net loss attributable$13 increase to common stockholders for the three months ended March 31, 2020,carrying value of $280 million, unrealized losses on investment securities of $146 million and translation losses on the consolidation of AFG's foreign subsidiaries of $46 million.redeemable NCI which is offset directly against retained earnings.

Reinsurance Recoverable on Paid and Unpaid Losses. Ambac AssuranceAAC has reinsurance in place pursuant to surplus share treaty and facultative agreements. To minimize its exposure to losses from reinsurers, Ambac AssuranceAAC (i) monitors the financial condition of its reinsurers; (ii) is entitled to receive collateral from its reinsurance counterparties under certain reinsurance contracts; and (iii) has certain cancellation rights that can be exercised by Ambac AssuranceAAC in the event of rating agency downgrades of a reinsurer (among other events and circumstances). Ambac AssuranceAAC benefited from letters of credit and collateral amounting to approximately $124 million$108 from its reinsurers at March 31, 2020.2021.  As of March 31, 20202021 and December 31, 2019,2020, reinsurance recoverable on paid and unpaid losses were $36 million$33 and $26 million,$33, respectively. The increase was primarily a result of adverse development in public finance and student loan insured exposures.
Insurance Intangible Asset. AtIntangible assets include (i) an insurance intangible asset that was established at the Fresh Start Reporting Date, an insurance intangible asset was recorded which representedrepresenting the difference between the fair value and aggregate carrying value of the financial guarantee insurance and reinsurance assets and liabilities. liabilities and (ii) intangible assets established as part of the acquisition of Xchange on December 31, 2020.
As of March 31, 20202021 and December 31, 2019,2020, the net insurance intangible asset was $406 millionassets were $391 and $427 million,$409, respectively. Other than through amortization, variance in the insurance intangible asset is solely from translation gains (losses)
from the consolidation of Ambac's foreign subsidiary (Ambac UK).
Derivative Assets and Liabilities. The interest rate derivative portfolio is positioned to benefit from rising rates as a partial economic hedge against interest rate exposure in the financial guarantee and investment portfolios. Derivative assets increaseddecreased from $75 million$93 at December 31, 2019,2020, to $88 million$74 as of March 31, 2020.2021. Derivative liabilities increaseddecreased from $90 million$114 at December 31, 2019,2020, to $137 million$86 as of March 31, 2020.2021. The net increasesdecreases resulted primarily from lowerhigher interest rates during the three months ended March 31, 2019,2021, with the effect on assets partially offset by higherlower counterparty credit adjustments.
Loss and Loss Expense Reserves and Subrogation Recoverable.Loss and loss expense reserves are based upon estimates of the ultimate aggregate losses inherent in the non-derivative portfolio for insurance policies issued to beneficiaries, including unconsolidated VIEs.
The evaluation process for determining the level of reserves is subject to certain estimates and judgments.

Ambac has exposure to various bond types issued in the debt capital markets. Our experience has shown that, for the majority of bond types, we have not experienced significant claims. The bond types that have experienced significant claims, including through commutations, are residential mortgage-backed securities (“RMBS”), student loan securities and public finance securities. These bond types represent 94% of our ever-to-date insurance claims recorded, with RMBS comprising 76%75%.

Variability of Expected Losses and Recoveries
Ambac’s management believes that the estimated future loss component of loss reserves (present value of expected net cash flows) are adequate to cover future claims presented, but there can be no assurance that the ultimate liability will not be higher than such estimates.
It is possible that our estimated future losses for insurance policies discussed above could be understated or that our estimated future recoveries could be overstated. We have attempted to identify possible cash flows related to losses and recoveries using more stressful assumptions than the probability-weighted outcome recorded. The possible net cash flows consider the highest stress scenario that was utilized in the development of our probability-weighted expected loss at March 31, 2020,2021, and assumes an inability to execute any commutation transactions with issuers and/or investors. Such stress scenarios are developed based on management’s view about all possible outcomes relating to losses and recoveries. In arriving at such view, management makes considerable judgments about the possibility of various future events. Although we do not believe it is possible to have stressed outcomes in all cases, it is possible that we could have stress case outcomes in some or even many cases. See “Risk Factors” in Part I, Item 1A as well as the descriptions of "RMBS Variability,"
"Public "Public Finance Variability," "Student Loan Variability," and "Other Credits, including Ambac UK, Variability," in Part II, Item 7 of the Company's 20192020 Annual Report on Form 10-K for further discussion of the risks relating to future losses and recoveries that could result in more highly stressed outcomes, and "Risk Factors" in Part II, Item 1A of this Quarterly Report on Form 10-Q as well as the descriptions of "RMBS Variability," "Public Finance Variability," "Student Loan Variability," and "Other Credits, including Ambac UK, Variability" appearing below.
The occurrence of these stressed outcomes individually or collectively would have a material adverse effect on our results of operations and financial condition and may result in materially adverse consequence for the Company, including (without limitation) impairing the ability of Ambac AssuranceAAC to honor its financial obligations; the initiation of rehabilitation proceedings against Ambac Assurance;
AAC; decreased likelihood of Ambac AssuranceAAC delivering value to AFG, through dividends or otherwise; and a significant drop in the value of securities issued or insured by AFG or Ambac Assurance.AAC.

RMBS Variability:
Ambac has exposure to the U.S. mortgage market primarily through direct financial guarantees of RMBS, including transactions collateralized by first and second liens.lien mortgages.
Changes to assumptions that could make our reserves under-estimated include an increase in interest rates, deterioration in housing prices, poor servicing, government intervention into the functioning of the mortgage market and the effect of a weakened economy characterized by growing unemployment and wage pressures. We utilize a model to project losses in our RMBS exposures and changes to reserves, either upward or downward, are not unlikely if we used a different model or methodology to project losses.
We established a representation and warranty subrogation recovery as further discussed in Note 6. Financial Guarantee Insurance Contracts to the Unaudited Consolidated Financial Statements included in Part I, Item 1 in this Form 10-Q. Our ability to realize RMBS representation and warranty recoveries is subject to significant uncertainty, including risks inherent in litigation;litigation, including adverse rulings or decisions in our cases or in litigations to which AAC is not a party that set precedents or resolve questions of law that impact our own claims; collectability of such amounts from counterparties (and/or their respective parents and affiliates); delays in realizing such recoveries, including as a result of trial delays due to court closures related to COVID-19 or other events; intervention by the OCI, which could impede our ability to take actions required to realize such recoveries; and uncertainty inherent in the assumptions used in estimating such recoveries. Additionally, our R&W actual subrogation recoveries could be significantly lower than our estimate of $1,738 million,$1,722, net of reinsurance, as of March 31, 2020,2021, if the sponsors of these transactions: (i) fail to honor their obligations to repurchase the mortgage loans, (ii) successfully dispute our breach findings or claims for damages, (iii) no longer have the financial means to fully satisfy
| Ambac Financial Group, Inc. 592021 First Quarter FORM 10-Q |



their obligations under the transaction documents, or (iv) our pursuit of recoveries is otherwise unsuccessful. Failure to realize R&W subrogation recoveries for any reason or the realization of R&W subrogation recoveries materially below the amount recorded on Ambac's consolidated balance sheet would have a material adverse effect on our results of operations and financial condition.
In the case of both first and second-lien exposures, the possible stress case assumes a lower housing price appreciation projection, which in turn drives higher defaults and severities. Using this approach, the possible increase in loss reserves for RMBS credits for which we have an estimate of expected loss at March 31, 20202021, could be approximately $25 million.$10. Combined with the absence of any R&W subrogation recoveries, a possible increase in loss reserves for RMBS could be approximately $1,763 million.$1,732. A loss of this magnitude may render AAC insolvent. Additionally, loss payments are sensitive to changes in interest rates, increasing as interest rates rise. For example, an increase in interest rates of 0.50% could increase our estimate of expected losses by approximately $40 million.$30. There can be no assurance that losses may not exceed such amounts. Additionally, the RMBS portfolio is
sensitive to the COVID-19 related forbearances and delinquencies caused by the general economic downturn. Due to the uncertainties related to the economic effects of the COVID-19 pandemic and other risks inherent associated with RMBS, there can be no assurance that losses may not exceed our stress case estimates.
Public Finance Variability:
Ambac’s U.S. public finance portfolio consists predominantly of municipal bonds such as general and revenue obligations and lease and tax-backed obligations of state and local government entities; however, the portfolio also includes a wide array of non-municipal types of bonds, including financings for not-for-profit entities and transactions with public and private elements, which generally finance infrastructure, housing and other public purpose facilities and interests. The increase in public finance gross loss reserves at March 31, 2020,2021, as compared to December 31, 2019,2020, was primarily related to declines in discount rates and the adverse impact on loss reserves from the global and issuer-specific economic impact of the COVID-19 pandemic.development related to Puerto Rico credits.

It is possible our loss reserves for public finance credits may be under-estimated if issuers are faced with prolonged exposure to adverse political, judicial, economic, fiscal or socioeconomic events or trends. Additionally, our loss reserves may be under-estimated as a result of the ultimate scope, duration and magnitude of the effects of COVID-19. The COVID-19 related economic downturn has put a strain on municipal issuers, particularly those dependent upon narrow sources of revenues or dedicated taxes to support debt services,service, such as hotel occupancy taxes, sales taxes, parking
revenues, tolls, licensing fees, etc. A prolonged recovery from the COVID-19 related economic downturnimpact could put additional stresses on these issuers as well as other types of municipal finance issuers and result in increased defaults and potential additional losses for Ambac.
Our experience with the city of Detroit in 2013 in its bankruptcy proceeding was not favorable and renders future outcomes with other public finance issuers even more difficult to predict and may


| Ambac Financial Group, Inc. 622020 First Quarter FORM 10-Q |



increase the risk that we may suffer losses that could be sizable. We agreed to settlements regarding our insured Detroit general obligation bonds that provide better treatment of our exposures than the city planned to include in its plan of adjustment, but nevertheless required us to incur a loss for a significant portion of our exposure. An additional troubling precedent in the Detroit case, as well as other municipal
bankruptcies, is the preferential treatment of certain creditor classes, especially the public pensions. The cost of pensions and the need to address frequently sizable unfunded or underfunded pensions is often a key driver of stress for many municipalities and their related authorities, including entities to whom we have significant exposure, such as Chicago's school district, the State of New Jersey and many others. Less severe treatment of pension obligations in bankruptcy may lead to worse outcomes for traditional debt creditors.
Variability of outcomes applies even to even what is generally considered more secure municipal financings, such as dedicated sales tax revenue bonds that capture sales tax revenues for debt service ahead of any amounts being deposited into the general fund of an issuer. In the case of the Puerto Rico COFINA sales tax bonds that were part of the Commonwealth of Puerto Rico's Title III proceedings, Ambac AssuranceAAC and other creditors agreed to settle at a recovery rate equal to about 93% of pre-petition amounts owed on the Ambac insured senior COFINA bonds. In the COFINA case, the senior bonds still received a reduction or "haircut" despite the existence of junior COFINA bonds, which received a recovery rate equal to about 56% of pre-petition amounts owed.
In addition, municipal entities may be more inclined to use bankruptcy to resolve their financial stresses if they believe

preferred outcomes for various creditor groups can be achieved. We expect municipal bankruptcies and defaults to continue to be challenging to project given the unique political, economic, fiscal, legal, governance and public policy differences among municipalities as well as the complexity, long duration and relative infrequency of the cases themselves in forums with a scarcity of legal precedent.
Another potentially adverse development that could cause the loss reserves on our public finance credits to be underestimated is deterioration in the municipal bond market, resulting from reduced or limited access to alternative forms of credit (such as bank loans) or other exogenous factors, such as the Tax Cuts and Jobs Actchanges in tax law that was signed into law on December 22, 2017, which could reduce certain municipal investors' appetite for tax-exempt municipal bonds and over the longer term could potentiallyor put additional pressure on issuers in states with high state and local taxes. These factors as well as more recent volatility in the municipal markets as a result of the COVID-19 related economic downturn and the building budgetary pressures at the state and local level related to the cost of fighting the virus could deprive issuers access to funding at a level necessary to avoid defaulting on their obligations.
In addition, a judicial decision in connection with the PRHTA Title III proceedings could cause the loss reserves on our public finance credits to be underestimated. On January 13, 2020, the U.S. Supreme Court denied a petition for certiorari arising out of an appeal toof the March 26, 2019, ruling by the U.S. Court of Appeals for the First Circuit. In the ruling, the First Circuit affirmed the decision by the U.S. District Court overseeing the PROMESA Title III proceedings for the PRHTA, which found that under Sections 928(a) and 922(d) of the U.S. Bankruptcy Code, municipal issuers
of revenue bonds secured by special revenues are permitted, but not required, to apply special revenues to pay debt service on such revenue bonds during the pendency of bankruptcy proceedings for such municipal issuers. The First Circuit's decision challenges what had been a commonly understood notion in the municipal finance marketplace that municipal revenuesrevenue bondholders secured by special revenues (as defined in Chapter 9 of the U.S. Bankruptcy Code) would continue to receive payment during a bankruptcy of the municipal issuer. This decision introduces uncertainty into the public finance market and it may make it more difficult for municipal instrumentalities to procure revenue bond financings in the future and increases the credit risk to bondholders of existing special revenue bonds, particularly those from weaker issuers.
While our loss reserves consider our judgment regarding issuers’ financial flexibility to adapt to adverse markets, they may not adequately capture sudden, unexpected or protracted uncertainty that adversely affects market conditions, such as the developing COVID-19 related economic downturn.impact.
Our exposures to the Commonwealth of Puerto Rico are under stress arising from the Commonwealth’s poorweak financial condition weakand economy, loss of capital markets access, and the severe damage caused by hurricanes Irma and Maria.Maria and other natural disasters as well as a narrow view on available debt capacity being taken by the Oversight Board and Commonwealth government. These factors, taken together with the payment moratorium on debt paymentsservice of the Commonwealth and its instrumentalities,instrumentalities; ongoing PROMESA Title III proceedings, andproceedings; certain other provisions under PROMESA, the potential forPROMESA; expected restructurings of debt insured by Ambac Assurance, AAC,
either with or without its consent,consent; uncertainty with regards to AAC's valuation of the CVI; and the possibility of protracted litigation as a result of which itsour rights may be materially impaired, may cause losses to exceed current reserves in a material manner. See "Financial Guarantees in Force" section of Management’s Discussion and Analysis of Financial Condition and Results of Operations included in Part II, Item 7 in the Company’s Annual Report on Form 10-K for the year ended December 31, 20192020, for further details on the legal, economic and fiscal developments that have impacted or may impact Ambac Assurance’sAAC’s insured Puerto Rico bonds. In this Form 10-Q, refer to "Financial Guarantees in Force" in Part I, Item 2 in Management's Discussion and Analysis of Financial Condition and Results of Operation, and Note 11.6. Financial Guarantee Insurance Contracts to the Unaudited Consolidated Financial Statements and Note 12. Commitments and Contingencies to the Unaudited Consolidated Financial Statements for further updates related to Puerto Rico.
Material additional losses on our public finance credits caused by the aforementioned factors, and including the possibility of a protracted recovery related to the COVID-19 crisis would have a material adverse effect on our results of operations and financial condition. For the public finance credits, including Puerto Rico, for which we have an estimate of expected loss at March 31, 2020,2021, the possible increase in loss reserves could be approximately $1,220 million.$660. However, there can be no assurance that losses may not exceed such amount.our stress case estimates. Among other things, this estimate includes the possibility that the amended Commonwealth plan of adjustment (as discussed above in the Financial Guarantees in Force section of this Management Discussion and Analysis) were to become effective.
Student Loan Variability:
Changes to assumptions that could make our reserves under-estimated include, but are not limited to, increases in interest rates, default rates and loss severities on the collateral due to economic

or other factors, including the COVID-19 related economic downturn.impact. Such factors may include lower recoveries on defaulted loans or additional losses on collateral or trust assets, including as a result of any enforcement actions by the Consumer Finance Protection Bureau. For student loan credits for which we have an estimate of expected loss at March 31, 2020,2021, the possible increase in loss reserves could be approximately $35 million.$25. Additionally, an increase in interest rates of 0.50% could increase our estimate of expected losses by approximately $20 million.$20. Additionally, the student loan portfolio is sensitive to COVID-19 related payment moratoriums and delinquencies caused by the general economic downturn. There can be no assurance that losses may not exceed our stress case estimates.
Other Credits, including Ambac UK, Variability:
It is possible our loss reserves on other types of credits, including those insured by Ambac UK, may be under-estimated because of various risks that vary widely, including the risk that we may not be able to recover or mitigate losses through our remediation processes. For all other credits, including Ambac UK, for which we have an estimate of expected loss, the sum of all the highest stress case loss scenarios is approximately $400 million$380 greater than the loss reserves at March 31, 2020.2021. Additionally, our loss reserves may be under-estimated as a result of the ultimate scope, duration
| Ambac Financial Group, Inc. 612021 First Quarter FORM 10-Q |



and magnitude of the effects of COVID-19. There can be no assurance that losses may not exceed our stress case estimates.
Long-term Debt:
Long-term debt consists of senior and junior surplus notes issued by Ambac Assurance,AAC, the Ambac Note and Tier 2 Notes issued in connection with the Rehabilitation Exit Transactions, and Ambac UK debt issued in connection with the 2019 Ballantyne commutation. The carrying value of each of these as of March 31, 20202021 and December 31, 20192020 is below:

AMBAC UK FINANCIAL RESULTS UNDER UK ACCOUNTING PRINCIPLES (£ in millions)
Ambac UK is required to prepare financial statements under FRS 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland." Ambac UK’s shareholder funds under UK GAAP were £380 million£420 at March 31, 2020,2021, as compared to
£387 million £412 at December 31, 2019.2020. At March 31, 2020,2021, the carrying value of cash and investments was £464 million, a decrease£485, an increase from £470 million£481 at December 31, 2019.2020. The decreaseincrease in shareholders’ funds and cash &and investments was primarily due to losses in the period within Ambac UK's investment portfolio, offset by foreign exchange gains and the continued receipt of premiums.premiums and investment income, partially offset by loss expenses, foreign exchange losses, operating expenses and tax payments.
Ambac UK is also required to prepare financial information in accordance with the Solvency II Directive.  The basis of preparation of this information is significantly different from both US GAAP and UK GAAP. 
Available capital resources under Solvency II were a surplus of £163 million£222 at March 31, 2020,2021, of which £149 million£212 were eligible to meet solvency capital requirements. This is a reductionan increase from December 31, 2019,2020, when available capital resources were a surplus of £188 million£196 of which £178 million£184 were eligible to meet solvency capital requirements.

The regulators are aware of the deficiency in capital resources as compared to capital requirements and dialogue between Ambac UK management and its regulators remains ongoing with respect to options for addressing the shortcoming, although such options remain few.
NON-GAAP FINANCIAL MEASURES
In addition to reporting the Company’s quarterly financial results in accordance with GAAP, the Company currently reports two non-GAAP financial measures: Adjusted Earnings and Adjusted Book Value. The most directly comparable GAAP measures are net income attributable to common stockholders for Adjusted Earnings and Total Ambac Financial Group, Inc. stockholders’ equity for Adjusted Book Value. A non-GAAP financial measure is a numerical measure of financial performance or financial position that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP. We are presenting these non-GAAP financial measures because they provide greater transparency and enhanced visibility into the underlying drivers of our business. Adjusted Earnings and Adjusted Book Value are not substitutes for the Company’s GAAP reporting, should not be viewed in isolation and may differ from similar reporting provided by other companies, which may define non-GAAP measures differently.
Ambac has a significant U.S. tax net operating loss (“NOL”) that is offset by a full valuation allowance in the GAAP consolidated financial statements. As a result of this and other considerations, we utilized a 0% effective tax rate for non-GAAP adjustments; which is subject to change.

Adjusted Earnings (Loss). Adjusted Earnings (Loss) is defined as net income (loss) attributable to common stockholders, as reported under GAAP, adjusted on an after-tax basis for the following:
Non-credit impairment fair value (gain) loss on credit derivatives: Elimination of the non-credit impairment fair value gains (losses) on credit derivatives, which is the amount in excess of the present value of the expected estimated credit losses. Such fair value adjustments are affected by, and in part fluctuate with changes in market factors such as interest rates and credit spreads, including the market’s perception of Ambac’s credit risk (“Ambac CVA”), and are not expected to result in an economic gain or loss. These adjustments allow for all financial guarantee contracts to be accounted for consistent with the Financial Services – Insurance Topic of ASC, whether or not they are subject to derivative accounting rules.

Non-credit impairment fair value losses on credit derivatives: Elimination of the non-credit impairment fair value loss on credit derivatives, which is the amount in excess of the present value of the expected estimated economic credit loss. GAAP fair values are affected by, and in part fluctuate with, changes in market factors such as interest rates, credit spreads, including Ambac’s CVA that are not expected to result in an economic gain or loss.

Net unearned premiums and fees in excess of expected losses: Addition of the value of the unearned premium Addition of the value of the unearned premium revenue ("UPR") on financial guarantee contracts, in excess of expected losses, net of reinsurance. This non-GAAP adjustment presents the economics of UPR and expected losses for financial guarantee contracts on a consistent basis. In accordance with GAAP, stockholders’ equity reflects a reduction for expected losses only to the extent they exceed UPR. However, when expected losses are less than UPR for a financial guarantee contract, neither expected losses nor UPR have an impact on stockholders’ equity.

The decrease in Adjusted Book Value was primarily attributable to the $13 reduction to retained earnings from the increase to the carrying value of redeemable NCI and the impact on expected future premiums from reinsurance and de-risking transactions, partially offset by the Adjusted Earnings for the three months ended March 31, 2020, and the impact of changes2021 (excluding earned premium previously included in foreign exchange rates resulting from the strengthening of the US Dollar.Adjusted Book Value).
Factors that impact changes to Adjusted Book Value include many of the same factors that impact Adjusted Earnings, including the majority of revenues and expenses, but generally exclude components of premium earnings since they are embedded in prior period's Adjusted Book Value through the net unearned premiums and fees in excess of expected losses adjustment. Net unearned premiums and fees in excess of expected losses will affect Adjusted Book Value for (i) changes to future premium assumptions (e.g. expected term, interest rates, foreign currency rates, time passage,passage), (ii) changes to expected losses for policies which do not exceed their related unearned premiums and (iii) new reinsurance transactions.

Item 3.    Quantitative and Qualitative Disclosure About Market risk represents the potential for losses that may result fromRisk'
As of March 31, 2021, there were no material changes in the value of a financial instrument as a result of changes in market conditions. The primary market risks that would impact the value of Ambac’s financial instruments are interest rate risk, credit spread risk and foreign currency risk. As a result of declines in interest rates and increases in credit spreads during the three months ended March 31, 2020, relatedCompany is exposed to the impact of the COVID-19 pandemic, along with portfolio adjustments during the period, the sensitivities of Ambac's financial instruments have changed from those disclosed in our Annual Report on Form 10-K for the year endedsince December 31, 2019.2020.
Interest Rate Risk:
Financial instruments for which fair value may be affected by changes in interest rates consist primarily of fixed income investment securities, long-term debtItem 4.     Controls and interest rate derivatives. Fixed income investment securities that are guaranteed by Ambac have interest rate risk characteristics that behave inversely to those associated with future financial guarantee claim payments. Accordingly, such securities are excluded from the interest rate sensitivity table that follows. Financial instruments of VIEs that are consolidated as a result of Ambac financial guarantees are also excluded from Ambac's measures of interest rate risk. Changes in fair value resulting from changes in interest rates are driven primarily by the impact of interest rate shifts on the fixed incomeProcedures.
investment portfolio (which produce net fair value losses as rates increase), long-term debt and the interest rate derivatives portfolio (which produce net fair value gains as rates increase). Interest rate increases would also have a negative economic impact on expected future claim payments within the financial guarantee portfolio, primarily related to RMBS and student loan policies. Ambac performs scenario testing to measure the potential for losses in volatile markets. These scenario tests include parallel and non-parallel shifts in the benchmark interest rate curve.
The interest rate derivatives portfolio is managed as a partial economic hedge against the effects of rising interest rates elsewhere in the Company, including on Ambac's financial guarantee exposures (the "macro-hedge"). At March 31, 2020, the interest rate sensitivity of the interest rate derivatives portfolio attributable to the macro-hedge position would produce mark-to-market gains or losses of approximately $0.1 million for a 1 basis point parallel shift in USD benchmark interest rates up or down at March 31, 2020. This sensitivity is down from $0.4 million per 1 basis point shift at December 31, 2019.
The following table summarizes the estimated change in fair value (based primarily on the valuation methodology discussed in Note 7. Fair Value Measurements to the Unaudited Consolidated Financial Statements included in Part I, Item 1 in this Form 10-Q) on these financial instruments, assuming immediate changes in interest rates at specified levels at March 31, 2020:

Due to the low interest rate environment as of March 31, 2020, stress scenarios involving interest rate declines greater than 200 basis points are not meaningful to Ambac's portfolios.

Credit Spread Risk
Financial instruments that may be adversely affected by changes in credit spreads include Ambac’s outstanding credit derivative contracts, certain interest rate derivatives and investment assets. Changes in spreads are generally caused by changes in the market’s perception of the credit quality of the underlying obligor. Market liquidity and prevailing risk premiums demanded by market participants are also reflected in spreads and impact valuations.
The following table summarizes the estimated change in fair values on Ambac’s net derivative liabilities assuming immediate parallel shifts in reference obligation credit spreads related to written credit derivatives and counterparty credit spreads related to uncollateralized interest rate derivatives at March 31, 2020. It is more likely that actual changes in credit spreads will vary by obligor:

 (26)
Also included in the fair value of derivatives is the effect of Ambac’s creditworthiness, which reflects market perception of Ambac’s ability to meet its obligations. Generally, the need for an Ambac credit valuation adjustment is mitigated by the existence of collateral posting agreements under which adequate collateral has been posted. Derivative contracts entered into with credit exposure to financial guarantee customers are not typically subject to collateral posting agreements. As a result of runoff of uncollateralized interest rate and credit default swap liabilities, Ambac’s credit valuation adjustment included in the determination of fair value has resulted in $0.1 million reduction to derivative liabilities as of March 31, 2020. Refer to Note 7. Fair Value Measurements to the Unaudited Consolidated Financial Statements included in Part I, Item 1 in this Form 10-Q for further information on measurement of the credit valuation adjustment.
Ambac’s fixed income investment portfolio contains securities with different sensitivities to and volatility of credit spreads. Fixed income securities that are guaranteed by Ambac and were purchased in Ambac's investment portfolio have credit spread risk characteristics that behave inversely to those associated with future financial guarantee claim payments. Accordingly such securities are excluded from the company's spread sensitivity measures. The following table summarizes the estimated change in fair values of Ambac’s fixed income investment portfolio assuming immediate shifts in credit spreads across all holdings other than Ambac guaranteed securities at March 31, 2020. It is more likely that actual changes in credit spreads will vary by security:

Item 4.Controls and Procedures.
In connection with the preparation of this first quarter Form 10-Q, an evaluation was carried out by Ambac’s management, with the participation of Ambac’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of Ambac’s disclosure controls and procedures (as defined in rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this Quarterly Report on Form 10-Q. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives. Based on its evaluation, Ambac’s Chief Executive Officer and Chief Financial Officer have concluded that, as of March 31, 2020,2021, Ambac’s disclosure controls and procedures were effective.
There were no changes in the Company’s internal control over financial reporting that occurred during the quarter ended March 31, 20202021, that materially affected, or are reasonably likely
to materially affect, the Company’s internal control over financial reporting. We have not experienced any significant change to our internal controls over financial reporting despite the fact that our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the COVID-19 situation on our internal controls to minimize the impact on their design and operating effectiveness.

Item 1A.    Risk Factors
You should carefully consider the risk factors set forth in the “Risk Factors” section, Item 1A to Part I in our Annual Report on Form 10-K for the year ended December 31, 2019,2020, which are hereby incorporated by reference. These important factors may cause our actual results to differ materially from those indicated by our forward-looking statements, including those contained in this report. Please also see the section entitled “Cautionary Statement Pursuant to the Private Securities Litigation Reform Act of 1995” in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of this quarterly report on Form 10-Q. There have been no material changes to the risk factors we have disclosed in the “Risk Factors” section of our aforementioned Annual Report on Form 10-K, other thanexcept as describednoted below.

Catastrophic public health events likerealize the COVID-19 pandemic that resultexpected recoveries included in material disruption of economic activity can have a materially negativeour financial statements could adversely impact on theour liquidity, financial performance of issuers of public finance obligations and issuers of structured finance obligations. Such stresses could result in liquidity claims and/or permanent losses on obligations of those issuers insured by Ambac.
The emergence of the COVID-19 pandemic and the resulting containment measures have caused economic and financial disruptions that have adversely affected, and are expected to continue to materially adversely affect, our businesscondition and results of operations.operations and the value of our securities, including the Secured Notes and Tier 2 Notes.
AAC is pursuing claims in litigation with respect to certain RMBS transactions that it insured. These claims are based on, among other things, representations with respect to the characteristics of the securitized loans, the absence of borrower fraud in the underlying loan pools or other misconduct in the
| Ambac insuresFinancial Group, Inc. 652021 First Quarter FORM 10-Q |



origination process, the compliance of loans with the prevailing underwriting policies, and compliance of the RMBS transaction counterparties with policies and procedures related to loan origination and securitization. In such cases, where contract claims are being pursued, the sponsor of the transaction is contractually obligated to repurchase, cure or substitute collateral for any loan that breaches the representations and warranties. However, generally the sponsors have not honored those obligations and have vigorously defended claims brought against them.
As of March 31, 2021, we have estimated RMBS R&W subrogation recoveries of $1,722 (net of reinsurance) included in our financial statements. These estimated recoveries are based on the contractual claims brought in the aforementioned litigations and represent a probability-weighted estimate of amounts we expect to recover under various possible scenarios. The estimated recoveries we have recorded do not represent the best or the worst possible outcomes with respect to any particular transaction or group of transactions.
There can be no assurance that AAC will be successful in prosecuting its claims in the RMBS litigations. The outcome of any litigation, including the RMBS litigations, is inherently unpredictable, including because of risks intrinsic in the adversarial nature of litigation. Motions made to the court, rulings and appeals - in the cases being prosecuted by AAC or in other relevant cases - could delay or otherwise impact any recovery by AAC. Moreover, rulings that may be adverse to AAC (in any of its RMBS litigations, as well as in other RMBS cases in which it is not a party, including an unrelated RMBS case with an appeal currently pending at the New York Court of Appeals involving issues relevant to AAC’s breach of contract claims) could adversely affect AAC’s ability to pursue its claims or the amount or timing of any recovery, or negatively alter settlement dynamics with RMBS litigation defendants. Any litigation award or settlement may be for an amount less than the amount necessary (even when combined with other pledged collateral) to pay the Secured Notes or the Tier 2 Notes, which could have a material adverse effect on our financial condition or results of operations and make it more difficult for AAC to repay the Ambac Note (and therefore make it more difficult for the issuer of the Secured Notes to repay the Secured Notes) and/or the Tier 2 Notes and/or AAC’s outstanding surplus notes, on a timely basis or at all. In the event that AAC is unable to satisfy its obligations with respect to the Ambac Note (and therefore make it more difficult for the issuer of the Secured Notes to satisfy its obligations in respect of the Secured Notes) or the Tier 2 Notes, holders will have the right to foreclose on any available collateral and to sue AAC for failure to make required payments; however, there can be no assurance that the sale of collateral will produce proceeds in an amount sufficient to pay any or all amounts due on the Secured Notes or the Tier 2 Notes, as the case may be, or that holders will be successful in any litigation seeking payments from AAC. Additionally, while AAC may pursue settlement negotiations, there can be no assurance that any settlement negotiations will materialize or that any settlement agreement can be reached on terms acceptable to AAC, or at all. Depending on the length of time required to resolve these litigations, either through settlement or at trial, AAC could incur greater litigation expenses than currently projected. If a case is brought to trial, AAC’s
ultimate recovery would be subject to the additional risks inherent in any trial, including adverse findings or determinations by the trier of fact or the court, which could adversely impact the value of our securities, including the Secured Notes and the Tier 2 Notes.
Any litigation award is subject to risks of recovery, including that a defendant is unable to pay a judgment that AAC may obtain in litigation. In some instances, AAC also has claims against a parent or an acquirer of the counterparty. However, AAC may not be successful in enforcing its claims against any successor entity.
The RMBS litigations could also be adversely affected if AAC does not have sufficient resources to actively prosecute its claims or becomes subject to rehabilitation, liquidation, conservation or dissolution, or otherwise impaired by actions of OCI.
Our ability to realize the estimated RMBS R&W subrogation recoveries included in our financial statements and the time of the recoveries, if any, is subject to significant uncertainty, including the risks described above and uncertainties inherent in the assumptions used in estimating such recoveries. The amount of these subrogation recoveries is significant and if we were unable to recover all such amounts, our stockholders’ equity as of March 31, 2021 would decrease from $1,123 to $(599).
We expect to recover material amounts of claims payments through remediation measures including the litigation described above as well as through cash flows in the securitization structures of transactions that AAC insures. Realization of such expected recoveries is subject to various risks and uncertainties, including the rights and defenses of other parties with interests that conflict with AAC’s interests, the performance of the collateral and assets backing the obligations that AAC insures, and the performance of servicers involved in securitizations in which AAC participates as insurer. Additionally, our ability to realize recoveries in insured transactions may be impaired if the continuing orders of the Rehabilitation Court are not effective.
Adverse developments with respect to any of the factors described above may cause our recoveries to fall below expectations, which could have a numbermaterial adverse effect on our financial condition, including our capital and liquidity, and may result in adverse consequences such as impairing the ability of issuersAAC to honor its financial obligations; the initiation of rehabilitation proceedings against AAC; decreased likelihood of AAC delivering value to AFG, through dividends or otherwise; diminished business prospects due to third party concerns about our ability to recover losses; and a significant drop in the value of securities issued or insured by AFG or AAC, including the Secured Notes and the Tier 2 Notes.
AAC insures obligations of the Commonwealth of Puerto Rico, including certain of its authorities and public corporations that are either subject to a Title III bankruptcy protection proceeding under the Puerto Rico Oversight, Management and Stability Act ("PROMESA") or have been, orotherwise suspended debt service payments. AAC has made and may continue to be required to make significant amounts of policy payments over the next several years, the recoverability of which is subject to great uncertainty, which may lead to material permanent losses. While we believe our reserves are adequate to cover losses on Puerto Rico insured bonds, there can be no assurance that AAC
| Ambac Financial Group, Inc. 662021 First Quarter FORM 10-Q |



may not incur additional losses in the future, be, substantially affected byparticularly given the uncertainty related to the ongoing Title III proceedings and the developing economic, effectspolitical and legal circumstances in Puerto Rico. Such losses may have a material adverse effect on AAC’s results of COVID-19, suchoperation and financial condition.
AAC has exposure to the Commonwealth of Puerto Rico (the "Commonwealth"), including its authorities and public corporations. Each has its own credit risk profile attributable to, as municipalitiesapplicable, discrete revenue sources, direct general obligation pledges and/or general obligation guarantees. AAC had approximately $1,067 of net par exposure to the Commonwealth and securitizations,these instrumentalities at March 31, 2021. Components of the overall Puerto Rico net par outstanding include capital appreciation bonds that are reported at the par amount at the time of issuance of the related insurance policy as opposed to the current accreted value of the bonds. The outstanding net insured amount including those backed by consumer loans such as mortgages or student loans. accretion on capital appreciation bonds is approximately $1,282 at March 31, 2021. Total net insured debt service outstanding (net par and interest) to the Commonwealth and its instrumentalities was approximately $2,486 at March 31, 2021.
As a result of the developments described more fully in Management'sthis Risk Factor and elsewhere in this Quarterly Report on Form 10-Q (see Part I, Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations municipalities and their authorities, agencies and instrumentalities, especially those dependent on narrow revenue streams flowing from particular economic activities, have suffered, and are expected to continue to suffer, from severely depressed revenues due to shelter-in-place orders, social distancing guidelines, travel bans and restrictions, and business shutdowns and an economic recession brought about by the COVID-19 pandemic. Furthermore, securitizations dependent on cash flows from payments on mortgage loans, student loans or other assets have experienced, and are expected to continue to experience, shortfalls in receipts due to borrower nonpayments. See Part I, Item 2 of this Form 10-Q, Management's Discussion and Analysis of Financial Condition and Results of Operations,Executive Summary, - Financial Guarantees in Force, and Balance Sheet Commentary for further detail.
The U.S. Federal governmentNote 6. Financial Guarantee Insurance Contracts to the Unaudited Consolidated Financial Statements included in Part I, Item 1 in this Quarterly Report on Form 10-Q), the Commonwealth and other governments globally have taken certain measuresof its instrumentalities are continuing to aid consumers, businesses, State and local governments, and the financial markets, but the impact of such aid remains unclear. U.S. Federal and State governments and their agencies have also adopted policies or guidelines to provide emergency relief to consumers, such as limiting debt collections efforts and encouraging or requiring extensions, modifications or forbearance, with respect to certain loans and fees. Such policies or guidelines may be expanded over time as the economic effects of the pandemic become more well known. To the extent such measures cause greater incidences of missed mortgage loan,
student loan or otherdefault on debt service payments, than would have occurred without governmental intervention, Ambacincluding payments owed on bonds insured by AAC. AAC has made, and may experience higher lossescontinue to be required to make, significant amounts of policy payments over the next several years, the recoverability of which is subject to great uncertainty, which may lead to material permanent losses. Our exposure to Puerto Rico is impacted by the amount of monies available for debt service, which is in its insured portfolio of asset-backed securities.
The ultimate impact of a catastrophic public health event like COVID-19 on issuers and their obligations, and the economy in general, is by its very nature uncertain, and will be determinedturn affected by a number of factors including but not limitedvariability in economic growth and demographic trends, tax revenues, changes in law or the effects thereof, essential services expense, federal funding of Commonwealth needs as well as interpretation of legislation, legal documents, and updated financial information (when available).
Substantial uncertainty also exists with respect to the depth and duration of the crisis; the extent to which affected consumers, businesses, municipal entities and other debtors or sources of revenues recover from depressed economic circumstances, and the timelinesultimate outcome for such recoveries; the level and efficacy of government support for municipal entities, consumers, businesses and the financial markets via emergency relief measures; the level and efficacy of state and local government support for consumers and businesses; the impact of governmental intervention; management of public health crisis remediation efforts; and certain socio-economic variables, such as unemployment levels. Consequently, if issuers do not have sufficient resources or financial flexibility, receive adequate measures of support or realize the appropriate level of economic recovery, their ultimate ability to service the debt insured by Ambac could be materially impaired and Ambac could suffer material permanent losses.
At this time, there are significant uncertainties surrounding the ultimate number of claims and the extent of losses Ambac will face as a result of the economic effects of the COVID-19 pandemic. Actual losses may vary materially from Ambac's loss and loss expense reservescreditors in Puerto Rico due to the factorsMarch 8, 2021, Second Amended Title III Joint Plan of Adjustment of the Commonwealth ("Second Amended POA") or changes thereto as well as legislation enacted by the Commonwealth and the United States, including PROMESA, as well as actions taken in reliance on such laws, including Title III filings. AAC is involved in multiple litigations relating to such actions and other issues and may not be successful in pursuing claims or protecting its interests.
Given the numerous uncertainties and risks existing with respect to the restructuring process, outcomes associated with the February 23, 2021, Second Amended Plan Support Agreement between the Oversight Board, as representative of the Commonwealth of Puerto Rico, PBA, and the Employee Retirement System of the Government of the Commonwealth of Puerto Rico, and a group of creditors reported to represent 70% of
all GO and PBA bonds claims ("Second Amended PSA"), the March 8, 2021, Second Amended POA, the May 5, 2021, agreement with the Oversight Board and two monoline financial guaranty companies (the "PRHTA/CCDA PSA"), or any changes thereto under the aforementioned plans and agreements and relevant litigation, no assurance can be given that ultimate debt service discounts will not be very severe and cause AAC to experience losses materially exceeding current reserves. It is possible that certain restructuring process solutions, together with associated legislation, budgetary, and/or public policy proposals could be adopted and could significantly further impair our exposures. In addition, there are possible final legal determinations, including failing to recognize or properly differentiate legal structures and protections applicable to such exposures, that could result in losses exceeding our current reserves by a material amount and further increases to our loss reserves. In particular, in a Title III process, should court-approved plans of adjustment for the Commonwealth, the Puerto Rico Highways and Transportation Authority ("PRHTA"), the Puerto Rico Public Buildings Authority ("PBA") or any other issuers of AAC’s insured debt that may or may not file for Title III protection contemplate discounts to debt service implied by, or even worse than, the newly certified Commonwealth fiscal plan (April 23, 2021) (the “Commonwealth Fiscal Plan”) or AAC receive unfavorable judgments in the litigations to which it is a party, AAC’s financial condition would be materially adversely affected.
For example, the Second Amended PSA provides for lower Commonwealth debt service payments per annum relative to the Plan Support Agreement signed in February 2020 (Amended PSA), extends the tenor of new recovery bonds, increases the amount of cash distributed to creditors, and provides additional consideration in the form of a contingent value instrument ("CVI"). This CVI is intended to provide creditors with additional returns tied to outperformance of the Puerto Rico Sales and Use Tax ("SUT") against certified 2020 Commonwealth Fiscal Plan projections. More specifically, fixed consideration as part of the Second Amended POA includes a combination of cash, new GO current interest bonds as well as new GO capital appreciation bonds. Recovery derived from fixed consideration is estimated to vary between approximately 67% and 77% (as of petition date) for GO creditors, and between approximately 75% and 80% (as of petition date) for PBA creditors.
Under the May 5, 2021, PRHTA/CCDA PSA, consideration for revenue bond creditors such as PRHTA, CCDA, or Puerto Rico Infrastructure Financing Authority ("PRIFA") Special Tax Revenue ("Rum Tax") bonds, on account of their deficiency claims ("Clawback claims") against the Commonwealth, consists of CVI tied to the outperformance of the SUT against the certified 2020 Commonwealth Fiscal Plan projections. Overall, CVI recoveries are subject to a lifetime cap of 75% of deficiency amounts. The value of the Clawback CVI is uncertain given the contingent, outperformance-driven structure of the instrument coupled with the likely back-ended aspects for the majority of the potential cash flows. In addition, under the PRHTA/CCDA PSA, the PRHTA creditors would receive 'hard currency' in the form of new PRHTA bonds totaling $1,245 and $389 of cash proceeds, including a $264 interim distribution, payable at the effective date of the Commonwealth plan of adjustment, and $125 of restriction
| Ambac Financial Group, Inc. 672021 First Quarter FORM 10-Q |



fees and consummation costs. Of the $264 interim cash distribution, $184.8 will be allocated to holders of PRHTA '68 bonds and $79.2 will be allocated to holders of PRHTA '98 bonds. Of the $1,245 in new PRHTA bonds, approximately $646.4 will be allocated to holders of PRHTA '68 bonds and approximately $598.6 will be allocated to holders of PRHTA '98 bonds. Claim recovery expectations for PRHTA creditors under the PRHTA/CCDA PSA agreement are uncertain and subject to interpretation due to the aforementioned uncertainty related to the value of the Clawback CVI.
Under the PRHTA/CCDA PSA, CCDA creditors would also receive $112 of cash, inclusive of up to $15 related to restriction fees and consummation costs, payable at the effective date of the Commonwealth plan of adjustment. PRIFA was not part of the PRHTA/CCDA PSA and, consequently, there are no additional recoveries provided for in the agreement for PRIFA beyond the proposed treatment of deficiency claims.
It is unclear how details under the agreements and plans described above may change. If the Second Amended POA was confirmed in its current form, AAC’s financial condition would be materially adversely affected. It is also possible that economic or demographic outcomes may be as, or worse than, forecasted in the Commonwealth Fiscal Plan or under proposals or plans promulgated by the Commonwealth or its instrumentalities in or in connection with a Title III process or otherwise. Even a negotiated restructuring to which AAC agrees as part of mediation or other process may involve material losses in excess of current reserves. While our reserving scenarios reflect a wide range of possible outcomes reflecting the significant uncertainty regarding future developments and outcomes, given our exposure to Puerto Rico and the inherenteconomic, fiscal, legal and political uncertainties in estimatingassociated therewith, our loss reserves may ultimately prove to be insufficient to cover our losses, given the evolving nature of the pandemicpotentially by a material amount, and itsmay be subject to material volatility. Changes to our loss reserves may have a material adverse impact on issuers of Ambac insured debt and the economy in general. Potential ultimate losses from the economic consequences of the COVID-19 pandemic could be material and therefore may have an adverse effect on ourAAC’s results of operations and financial condition.
