Ambac Assurance and Ambac UK's outstanding insurance policies generally guarantee payment when due of the principal and interest on the obligations guaranteed.
Management reviews financial information, allocates resources and measures financial performance on a consolidated basis. As a result, the Company has a single reportable segment.
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 Assurance and its subsidiaries through transaction terminations, policy commutations, reinsurance, settlements and restructurings, 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

• | Evaluation of opportunities in certain business sectors that meet acceptable criteria that will generate long-term stockholder value with attractive risk-adjusted returns.

With respect to our new business strategy, we continue to evaluate and pursue strategic opportunities in insurance, credit, 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 an acquisition or develop any new businesses or assets. As a consequence of the novel 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’s strategy to extract and increase the value of its investment in Ambac Assurance 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, Ambac Credit Products LLC ("ACP"), AFG and certain counterparties to credit default swaps with ACP that were guaranteed by Ambac Assurance, as well as the Stipulation and Order among the OCI (as defined below), AFG and Ambac Assurance that became effective on February 12, 2018, as amended (the “Stipulation and Order”), and in the indenture for the Tier 2 Notes issued by Ambac Assurance on February 12, 2018, each of which requires the Office of the Commissioner of Insurance for the State of Wisconsin (“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. 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 to extract and increase the value of its investment in Ambac Assurance is also subject to significantly more risk and uncertainty due to the consequences of the COVID-19 pandemic on the global economy, issuers of debt insured by Ambac, and issuers of debt and other investments owned by Ambac. These consequences may include material losses in Ambac's insured and investment portfolios, higher earnings volatility, increased liquidity demands and greater counterparty risk.
Opportunities for remediating losses on poorly performing insured transactions also depend on market conditions, including the perception of Ambac Assurance’s creditworthiness, the structure of the underlying risk and associated policy as well as other counterparty specific factors. Ambac Assurance's ability to commute policies or purchase certain investments may also be limited by available liquidity.

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 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 Presentation
The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial reporting and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by GAAP for annual periods. These 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. 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 and six months ended June 30, 2020, may not be indicative of the results that may be expected for the year ending December 31, 2020. The December 31, 2019, 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 $3 and $13 for the six months ended June 30, 2020 and 2019, 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.

Reclassifications and 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 Debt 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 June 30, 2020 was $13.
Refer to Note 8. Investments for further credit impairment disclosures.

Amortized cost assets
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 issuer's ability and willingness to pay its insured debt obligation impacts the payment of policy losses by Ambac as well as the receipt of premiums from the issuer. 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 Disclosures
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The 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 amendments related to changes in unrealized gains 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 for 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 the new guidance a reporting entity must consider indirect interests held through related parties under common control on a proportional 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 this ASU did not 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 impact 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 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
A mbac, 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 a 2018 Stipulation and Order, the OCI requires Ambac Assurance to obtain their 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 Assurance 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.

(Dollar Amounts in Millions, Except Share Amounts)
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 recognize a gain or loss for the difference between: (i) the fair value of any consideration received, the fair value of any retained non-controlling investment in the VIE and the carrying amount of any non-controlling interest in the VIE and (ii) the carrying amount of the VIE’s assets and liabilities. Gains or losses from consolidation and deconsolidation that are reported in earnings are reported within Income (loss) on variable interest entities on the Consolidated Statements of Total Comprehensive Income (Loss).

• | The impact of consolidating such FG VIEs on Ambac’s balance sheet is the elimination of transactions between the consolidated FG VIEs and Ambac’s operating subsidiaries and the inclusion of the FG VIE’s third party assets and liabilities. For a financial guarantee insurance policy issued to a consolidated VIE, Ambac does not reflect the financial guarantee insurance policy in accordance with the related insurance accounting rules under the Financial Services –

Insurance Topic of the ASC. Consequently, upon consolidation, Ambac eliminates the insurance assets and liabilities associated with the policy from the Consolidated Balance Sheets. Such insurance assets and liabilities may include premium receivables, reinsurance recoverable, deferred ceded premium, subrogation recoverable, unearned premiums, loss and loss expense reserves, ceded premiums payable and insurance intangible assets. For investment securities owned by Ambac that are debt instruments issued by the VIE, the investment securities balance is eliminated upon consolidation.
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 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.

As further discussed in Note 7. Financial Guarantee Insurance Contracts 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, on February 12, 2019, in connection with the COFINA POA, the COFINA Class 2 Trust was established. Ambac was required to consolidate the COFINA Class 2 Trust, which resulted in a gain of $15. The 2019 balance sheet impact of this additional VIE on the date of consolidation was an increase to total consolidated assets and liabilities by $292 and $364, respectively. Ambac did not consolidate any new VIE for the six months ended June 30, 2020. Ambac deconsolidated one VIE for the three and six months ended June 30, 2020, and no VIEs for the three and six months ended June 30, 2019. This VIE was

(1) | Maximum exposure to loss represents the maximum future payments of principal and interest on insured obligations and derivative contracts. Ambac’s maximum exposure to loss does not include the benefit of any financial instruments (such as reinsurance or hedge contracts) that Ambac may utilize to mitigate the risks associated with these variable interests.

(2) | Insurance assets represent the amount included in “Premium receivables” and “Subrogation recoverable” for financial guarantee insurance contracts on Ambac’s Consolidated Balance Sheets.

(3) | Insurance liabilities represent the amount included in “Loss and loss expense reserves” and “Unearned premiums” for financial guarantee insurance contracts on Ambac’s Consolidated Balance Sheets.

(4) | Net derivative assets (liabilities) represent the fair value recognized on credit derivative contracts and interest rate swaps on Ambac’s Consolidated Balance Sheets.

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 June 30, 2020 and December 31, 2019 the fair value of this entity was $2 and $3, respectively, and is reported within Other assets on the Consolidated Balance Sheets.

• | Total principal amount of debt outstanding was $377 and $403 at June 30, 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 June 30, 2020 and weighted average life of 0.6 years. The purchase by this entity of financial assets was financed through the issuance of MTNs, which are cross-collateralized by the purchased assets. The MTNs have the same expected weighted average life as the purchased assets. Derivative contracts (interest rate swaps) are used within the entity for economic

hedging purposes only. Derivative positions were established at the time MTNs were issued to purchase financial assets. As of June 30, 2020 Ambac Assurance had financial guarantee insurance policies issued for all assets, MTNs and derivative contracts owned and outstanding by the entity.

• | Insurance premiums paid to Ambac Assurance by this entity are earned in a manner consistent with other insurance policies, over the risk period. Additionally, any losses incurred on such insurance policies are included in Ambac’s Consolidated Statements of Total Comprehensive Income (Loss). Under the terms of an Administrative Agency Agreement, Ambac provides certain administrative duties, primarily collecting amounts due on the obligations and making interest payments on the MTNs.

On August 28, 2014, Ambac monetized its ownership of the junior surplus note issued to it by Ambac Assurance by depositing the junior surplus note into a newly formed VIE trust in exchange for cash and an owner trust certificate, which represents Ambac's right to residual cash flows from the junior surplus note. Ambac does not consolidate the VIE since it does not have a variable interest in the
trust. Ambac reports its owner trust certificate as an equity investment within Other investments on the Consolidated Balance Sheets with associated results from operations included within Net investment income (loss): Other investments on the Consolidated Statements of Total Comprehensive Income (Loss). The equity investment had a carrying value of $49 and $46 as of June 30, 2020 and December 31, 2019, respectively.
On February 12, 2018, Ambac formed a VIE, Ambac LSNI, LLC ("Ambac LSNI"). Ambac LSNI issued Secured Notes in connection with the Rehabilitation Exit Transactions. Ambac does not consolidate the VIE since it does not have a variable interest in the trust. Ambac reports its holdings of Secured Notes within Fixed Income Securities in the Consolidated Balance Sheets. The carrying value of Secured Notes held by Ambac was $467 and $535 at June 30, 2020 and December 31, 2019, respectively. Ambac's debt obligation to the VIE (the Ambac Note) had a carrying value of $1,659 and $1,763 at June 30, 2020 and December 31, 2019, respectively, and is reported within Long-term debt on the Consolidated Balance Sheets.

5. NET INCOME PER SHARE
As of June 30, 2020, 45,808,256 shares of Ambac's common stock (par value $0.01) and warrants entitling holders to acquire up to 4,877,749 shares of new common stock at an exercise price of $16.67 per share were issued and outstanding. Common shares outstanding increased by 252,856 during the six months ended June 30, 2020, primarily due to settlements of employee restricted and performance stock units.
Basic net income per share is computed by dividing net income attributable to common stockholders by the weighted-average
number of common shares outstanding and vested restricted stock units (together, "Basic Weighted Average Shares Outstanding"). Diluted net income per share is computed by dividing net income attributable to common stockholders by the Basic Weighted Average Shares Outstanding plus all potential dilutive common shares outstanding during the period. All potential dilutive common shares outstanding consider common stock deliverable pursuant to warrants, vested and unvested options, unvested restricted stock units and performance stock units granted under existing compensation plans.
The following table provides a reconciliation of the common shares used for basic net income per share to the diluted shares used for diluted net income per share:

|  | Three Months Ended June 30, |  | Six Months Ended June 30,
|  | 2020 |  | 2019 |  | 2020 |  | 2019
Basic weighted average shares outstanding |  | 46,166,666 |  |  | 45,986,043 |  |  | 46,113,495 |  |  | 45,909,595 |

Warrants |  | — |  |  | — |  |  | — |  |  | — |
Restricted stock units |  | — |  |  | — |  |  | — |  |  | — |
Performance stock units (2) |  | — |  |  | — |  |  | — |  |  | — |
Diluted weighted average shares outstanding |  | 46,166,666 |  |  | 45,986,043 |  |  | 46,113,495 |  |  | 45,909,595 |
Anti-dilutive shares excluded from the above reconciliation: |  |  |  |  |  |  |  |
Stock options |  | 16,667 |  |  | 16,667 |  |  | 16,667 |  |  | 16,667 |
Warrants |  | 4,877,749 |  |  | 4,877,783 |  |  | 4,877,757 |  |  | 4,877,783 |
Restricted stock units |  | 288,562 |  |  | 263,151 |  |  | 262,395 |  |  | 244,202 |
Performance stock units (2) |  | 997,841 |  |  | 699,038 |  |  | 929,057 |  |  | 651,310 |

(1) | For the three and six months ended June 30, 2020, and the three and six months ended June 30, 2019, Ambac had a net loss and accordingly excluded all potentially dilutive securities from the determination of diluted loss per share as their impact was anti-dilutive.

(2) | Performance stock units are reflected based on the performance metrics through the balance sheet date. Vesting of these units is contingent upon meeting certain performance metrics. Although a portion of these performance metrics have been achieved as of the respective period end, it is possible that awards may no longer meet the metric at the end of the performance period.

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 June 30, 2020 and December 31, 2019, was 2.1% and 2.4%, respectively, and the weighted average period of future premiums used to estimate the premium receivable at June 30, 2020 and December 31, 2019, was 8.6 years and 8.5 years, respectively.

Below is the gross premium receivable roll-forward for the respective periods, net of allowance for credit losses:

Changes to allowance for credit losses |  | (4 | ) |  | (1 | )
Other adjustments (including foreign exchange) |  | (8 | ) |  | (11 | )
Ending premium receivable (2) |  | $ | 392 |  |  | $ | 442 |

(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 June 30, 2020 and 2019, premium receivables include British Pounds of $127 (£103) and $137 (£108), respectively, and Euros of $22 (€19) and $28 (€25), respectively.

When a bond issue insured by Ambac Assurance has been retired early, typically due to an issuer call, any remaining UPR is recognized at that time to the extent the financial guarantee contract is legally extinguished, causing accelerated premium revenue. For installment premium paying transactions, we offset the recognition of any remaining UPR by the reduction of the related premium receivable to zero (as it will not be collected as a result of the retirement), which may cause negative accelerated premium revenue. Ambac’s accelerated premium revenue for retired obligations for the three and six months ended June 30, 2020, was $1 and $1, respectively and for the three and six months ended June 30, 2019, was $(6) and $6.

(1) | Future premiums to be collected are undiscounted, gross of allowance for credit losses, and are used to derive the discounted premium receivable asset recorded on Ambac's balance sheet.

(2) | Future premiums to be earned, net of reinsurance relate to the unearned premiums liability and deferred ceded premium asset recorded on Ambac’s balance sheet. The use of contractual lives for many bond types which do not have homogeneous pools of underlying collateral is required in the calculation of the premium receivable, as 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, 2019. This results in a different premium receivable balance than if expected lives were considered. If installment paying policies are retired or prepay early, premiums reflected in the premium receivable asset and amounts reported in the above table for such policies may not be collected. Future premiums to be earned also considers the use of contractual lives for many bond types which do not have homogeneous pools of underlying collateral, which may result in different unearned premium than if expected lives were considered. If those bonds types are retired early, premium earnings may be negative in the period of call or refinancing.

Credit impairment (Premium receivables and reinsurance recoverables):
Management evaluates premium receivables and reinsurance recoverables for expected credit losses ("credit impairment") in accordance with the CECL standard adopted January 1, 2020, which is further described in Note 2. Basis of Presentation and Significant Accounting Policies. 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 previously under GAAP.
As further discussed in Note 2. Basis of Presentation and Significant Accounting Policies, 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. Below is the amortized cost basis of premium receivables by risk classification code and asset class as of June 30, 2020:

Below is a rollforward of the premium receivable allowance for credit losses as of June 30, 2020:

|  | Three Months Ended June 30, 2020 |  | Six Months Ended June 30, 2020

Recoveries of previously written-off amounts |  | — |  |  | — |
Ending balance |  | $ | 16 |  |  | $ | 16 |

(1) | At December 31, 2019, $9 of premiums receivable were deemed uncollectible as determined under prior GAAP rules.

(2) | The six months ended June 30, 2020, includes $3 from the adoption of CECL.

At June 30, 2020, Ambac had past due premiums of $2, of which $1 was over 120 days past due and has been included in the allowance for credit losses.
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 has recorded a recoverable, the fair value of collateral posted by the reinsurer to Ambac Assurance exceeds Ambac Assurance's reinsurance recoverable carrying value, net of ceded premiums payable. Ambac Assurance has credit exposure of $2 and has recorded an allowance for credit losses of less than a million dollars at June 30, 2020.
Loss and Loss Expense Reserves:
Ambac’s loss and loss expense reserves (“loss reserves”) are based on management’s on-going review of the financial guarantee credit portfolio. Below are the components of the loss reserves liability and the Subrogation recoverable asset at June 30, 2020 and December 31, 2019:

(1) | Total losses and loss expenses (benefit) includes $(11) and $(6) for the six months ended June 30, 2020 and 2019, respectively, related to ceded reinsurance.

(2) | Ambac records the impact of estimated recoveries related to securitized loans in RMBS transactions that breached certain representations and warranties ("R&W"s) by transaction sponsors within losses and loss expenses (benefit). The losses and loss expense (benefit) incurred associated with changes in estimated R&Ws for the six months ended June 30, 2020 and 2019, was $(30) and $8, respectively.

(3) | Represents reinsurance recoverable on future loss and loss expenses. Additionally, the Balance Sheet line "Reinsurance recoverable on paid and unpaid losses" includes reinsurance recoverables (payables) of $1 and $0 as of June 30, 2020 and 2019, respectively, related to previously presented loss and loss expenses and subrogation.

For 2020, the adverse development in prior years was primarily a result of deterioration in Public Finance credits, primarily Puerto Rico credits as discussed below in the section, "Puerto Rico", partially offset by positive development in the RMBS portfolio.
For 2019, the positive development in prior years was primarily a result of the Ballantyne and Puerto Rico COFINA commutations and positive development in the RMBS portfolio, partially offset by deterioration in other Public Finance credits, primarily Puerto Rico credits other than COFINA.

COVID-19:
As a result of the COVID-19 related economic impact on issuers and markets where Ambac provides financial 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. The duration and depth of the recession; actions such as monetary policy and fiscal stimulus, including the CARES Act in the US that was signed into law on March 27, 2020, and future fiscal stimulus programs; and our insured obligors' financial flexibility and ability to mitigate the operational and economic impact of the recession will determine the ultimate impact to Ambac's insured portfolio. Accordingly, our loss reserves may be under-estimated as a result of the ultimate scope, duration and magnitude of the effects of COVID-19.
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. 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 are expected to continue to default on debt service payments, including payments owed on bonds insured by Ambac Assurance. Ambac Assurance 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 Commonwealth's willingness to make debt service payments as well as the amount of monies available for debt service, which is in turn affected by a number of

factors including demographic trends, economic conditions (including the impact from the COVID-19 pandemic), tax policy and revenues, impact of reforms, fiscal plans, government actions, political instability, budgetary performance and flexibility, weather and seismic events, litigation outcomes, as well as federal funding of Commonwealth needs. In the near term, the financial and economic outlook for Puerto Rico is dependent upon a still fragile infrastructure in the wake of hurricanes and earthquakes, heightening its vulnerability to additional natural disasters. The longer 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.
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 claim potential, risk profile and long-term financial strength.
Substantial uncertainty exists with respect to the ultimate outcome for creditors in Puerto Rico, such as Ambac Assurance, due to, amongst other matters, legislation enacted by the Commonwealth and the federal government, including PROMESA; 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 Assurance is involved in multiple litigations relating to 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 Assurance may not be respected.
Ambac Assurance has participated and may continue to participate in mediation related to potential debt restructurings. Mediation may not be productive or may not resolve Ambac Assurance's claims in a manner that 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 Plans of Adjustment will be approved by the Title III court and completed, or that any transaction or Plan of Adjustment will not have a material adverse impact on Ambac's financial condition or results of operations. 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 natural disasters in the island, 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.
Ambac has considered these developments and other factors in evaluating its Puerto Rico loss reserves. During the three and six months ended June 30, 2020, Ambac had incurred losses associated with its Domestic Public Finance insured portfolio of $42 and $220, respectively, which were primarily driven by strengthening of reserves related to the continued uncertainty and volatility of the situation in Puerto Rico and, for the six months ended June 30, 2020, lower discount rates. 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 Assurance to honor its financial obligations; the initiation of rehabilitation proceedings against Ambac Assurance; decreased likelihood of Ambac Assurance 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. For public finance credits, including Puerto Rico, for which Ambac has an estimate of expected loss at June 30, 2020, the possible increase in loss reserves under stress or other adverse conditions and circumstances was estimated to be approximately $1,200. 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 June 30, 2020, would decrease from $1,129 to $(71). There can be no assurance that losses may not exceed such amount.
Representation and Warranty Recoveries:
Ambac records estimated subrogation recoveries for breaches of R&Ws by sponsors of certain RMBS transactions. For a discussion of the approach utilized to estimate 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.
Ambac has recorded R&W subrogation recoveries of $1,757 ($1,731 net of reinsurance) and $1,727 ($1,702 net of reinsurance) at June 30, 2020 and December 31, 2019, 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. Background and Business Description 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.

Below is the rollforward of R&W subrogation for the affected periods:

| Six Months Ended June 30,
| 2020 |  | 2019
Discounted R&W subrogation (gross of reinsurance) at beginning of period | $ | 1,727 |  |  | $ | 1,771 |
All other changes (1) | 30 |  |  | (8 | )
Discounted R&W subrogation (gross of reinsurance) at end of period | $ | 1,757 |  |  | $ | 1,762 |

(1) | All other changes which may impact RMBS R&W subrogation recoveries include changes in 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; 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 and may result in adverse consequences such as impairing the ability of Ambac Assurance to honor its financial obligations; the initiation of rehabilitation proceedings against Ambac Assurance; decreased likelihood of Ambac Assurance 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.
Insurance intangible asset:
The insurance intangible amortization expense is included in the Consolidated Statements of Total Comprehensive Income (Loss), as shown below.

|  | Three Months Ended June 30, |  | Six Months Ended June 30,
|  | 2020 |  | 2019 |  | 2020 |  | 2019
Insurance amortization expense |  | $ | 14 |  |  | $ | 226 |  |  | $ | 27 |  |  | $ | 263 |

The insurance intangible asset and accumulated amortization are included in the Consolidated Balance Sheets, as shown below.

|  | June 30, 2020 |  | December 31, 2019
Gross carrying value of insurance intangible asset |  | $ | 1,260 |  |  | $ | 1,273 |
Accumulated amortization of insurance intangible asset |  | 868 |  |  | 847 |
Net insurance intangible asset |  | $ | 392 |  |  | $ | 427 |

The estimated future amortization expense for the net insurance intangible asset is as follows:

Amortization expense (1) (2) |  |
2020 (six months) |  | $ | 21 |
2021 |  | 38 |
2022 |  | 35 |
2023 |  | 32 |
2024 |  | 29 |
Thereafter |  | 237 |

(1) | The insurance intangible asset will be amortized using a level-yield method based on par exposure of the related financial guarantee insurance or reinsurance contracts. Future amortization considers the use of contractual lives for many bond types which do not have homogeneous pools of underlying collateral. Actual maturities will differ from contractual maturities because borrowers may have the right to call or prepay certain obligations. If those bonds types are retired early, amortization expense may differ in the period of call or refinancing.

(2) | The weighted-average amortizations period is 7.6 years.

7. 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:

l | Level 1 |  | Quoted 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.
l | Level 2 |  | Quoted 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 income 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.
l | Level 3 |  | Model 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 income 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 June 30, 2020 and December 31, 2019, 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 income 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 Income Securities:
The fair values of fixed income investment securities are based primarily on market prices received from quotes or alternative pricing sources. Because many fixed income 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 income 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 June 30, 2020, approximately 4%, 94% and 2% of the fixed income investment portfolio
(excluding variable interest entity investments) was valued using broker quotes, alternative pricing sources and internal valuation models, respectively. At December 31, 2019, approximately 4%, 94% and 2% of the fixed income 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 income 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 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 income securities classified as Level 3 is included below:
Other asset-backed securities: This security is a subordinated tranche of a resecuritization collateralized by Ambac-insured military housing bonds. The fair value classified as Level 3 was $66 and $72 at June 30, 2020 and December 31, 2019, 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 June 30, 2020 and December 31, 2019 include the following:

June 30, 2020:
a. Coupon rate: | 5.97%
b. Average Life: | 15.18 years
c. Yield: | 13.10%
December 31, 2019:
a. Coupon rate: | 5.97%
b. Average Life: | 15.58 years
c. Yield: | 11.75%

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. Investments for additional information about such investments in

pooled funds that are reported at fair value using NAV as a practical expedient.
Other investments also includes Ambac's equity interest in a non-consolidated VIE created in connection with Ambac's monetization of Ambac Assurance junior surplus notes. This equity interest is carried under the equity method. Fair value for the non-consolidated VIE equity interest is internally calculated using a market approach and is classified as Level 3.
Derivative Instruments:
Ambac’s derivative instruments primarily comprise interest rate swaps, credit default swaps and exchange traded futures contracts. Fair value is determined based upon market quotes from independent sources, when available. When independent 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 fair value of credit derivative liabilities was reduced by less than a million dollars at June 30, 2020 and December 31, 2019, 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 June 30, 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 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 expected 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 internal credit rating of
AA at June 30, 2020. 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, 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 Assurance 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 VIEs consolidated under the Consolidation Topic of the ASC consist primarily of fixed income securities, loans, derivative and debt instruments and are generally carried at fair value. These consolidated VIEs are securitization entities which have liabilities and/or assets guaranteed by Ambac Assurance or Ambac UK. The fair values of VIE 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 prices received from independent market 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. For those instruments where quotes were not available or cannot be reasonably corroborated, fair values are based on internal valuation models. Comparable to the sensitivities of investments in fixed income 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 VIE debt.
VIE derivative asset and liability fair values are determined using valuation models. When specific derivative contractual terms are available and may be valued primarily by reference to interest rates, foreign exchange rates and yield curves that are observable and regularly quoted, the derivatives are valued using vendor-developed models. Other derivatives within the VIEs that include significant unobservable valuation inputs are valued using internally developed models. VIE derivative liability fair value balances at June 30, 2020

and December 31, 2019 were developed using vendor-developed models and do not use significant unobservable inputs.
The fair value of VIE assets are obtained from market quotes when available. Typically 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 valuations of VIE assets (fixed income securities or loans), therefore, are generally derived from the fair value of notes and derivatives, as described above, adjusted for the fair value of cash flows from Ambac’s financial guarantee. The fair value of financial guarantee cash flows include: (i) estimated future premiums discounted at a rate consistent with that implicit in the fair value of the VIE’s liabilities and (ii) internal estimates of future loss 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-weighted average rate of 3.0% and 2.7% at June 30, 2020 and December 31, 2019, respectively. At June 30, 2020, the range of these discount rates was between 2.1% and 5.8%. 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 2020 and 2019. 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 June 30, 2020 and December 31, 2019, 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 June 30, 2020, includes the expectation that all principal and interest payments on securities guaranteed by Ambac Assurance or Ambac UK will be made timely and in full.
As of June 30, 2020, corporate securities in an unrealized loss position included $467 of Secured Notes issued by Ambac LSNI with an unrealized loss $6. The Secured Notes are insured under a financial guarantee policy issued by Ambac Assurance.
Ambac’s assessment about whether a decline in value is other-than-temporary reflects management’s current judgment regarding facts and circumstances specific to a security and other factors. If that judgment changes, Ambac may record a charge for credit impairment in future periods.

The following table presents a roll-forward of Ambac’s cumulative credit losses on debt securities for which a portion of an other-than-temporary impairment was recognized in other comprehensive income under prior GAAP for the six months ended June 30, 2019:

Balance, beginning of period |  | $ | 12 |
Reductions for credit impairments previously recognized on: |  |
Securities that matured or were sold during the period |  | (1 | )
Balance, end of period |  | $ | 12 |

Ambac had zero allowance for credit losses at June 30, 2020.
Ambac did not purchase any financial assets with credit deterioration for the six month period ended June 30, 2020.
Counterparty Collateral, Deposits with Regulators and Other Restrictions:
Ambac routinely pledges and receives collateral related to certain transactions. Securities held directly in Ambac’s investment portfolio with a fair value of $155 and $85 at June 30, 2020 and December 31, 2019, respectively, were pledged to derivative counterparties. Ambac’s derivative counterparties have the right to re-pledge the investment securities and as such, these pledged securities are separately classified on the Consolidated Balance Sheets as “Fixed income securities pledged as collateral, at fair value”. Refer to Note 9. Derivative Instruments for further information on cash collateral. There were no securities received from other counterparties that were re-pledged by Ambac.
Securities carried at $7 and $6 at June 30, 2020 and December 31, 2019, respectively, were deposited by Ambac and Everspan with governmental authorities or designated custodian banks as required by laws affecting insurance companies. Invested assets carried at $1 at June 30, 2020 and December 31, 2019 were deposited as security in connection with a letter of credit issued for an office lease.
Securities with a fair value of $184 and $197 at June 30, 2020 and December 31, 2019, respectively, were pledged as collateral and as sources of funding to repay the Secured Notes issued by Ambac LSNI. The securities may not be transferred or repledged by Ambac LSNI. Collateral may be sold to fund redemptions of the Secured Notes. Ambac Assurance also pledged for the benefit of the holders of Secured Notes (other than Ambac Assurance) the proceeds of interest payments and partial redemptions of the Secured Notes held by Ambac Assurance. The amount of such proceeds held by Ambac Assurance was $15 and $55 at June 30, 2020 and December 31, 2019, respectively, and is included in Restricted cash on the Consolidated Balance Sheet. Ambac Assurance may, from time to time, sell all or a portion of the Secured Notes it owns. In the event that Ambac Assurance sells any of the Secured Notes it owns, the proceeds must be used to redeem a like amount of the Ambac Note at par. The price at which Ambac Assurance sells the Secured Notes may differ from the price at which it redeems the Secured Notes.
Guaranteed Securities:
Ambac’s fixed income portfolio includes securities covered by guarantees issued by Ambac Assurance and other financial guarantors (“insured securities”). The published rating agency ratings on these securities reflect the higher of the financial strength rating of the financial guarantor or the rating of the underlying issuer. Rating agencies do not always publish separate underlying ratings (those ratings excluding the insurance by the financial guarantor). In the event these underlying ratings are not available from the rating agencies, Ambac will assign an internal rating. The following table represents the fair value, including the value of the financial guarantee, and weighted-average underlying rating, excluding the financial guarantee, of the insured securities at June 30, 2020 and December 31, 2019, respectively:

|  | Municipal Obligations |  | Corporate Obligations (2) |  | Mortgage and Asset- backed Securities |  | Total |  | Weighted Average Underlying Rating (1)

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 the outstanding credit derivative transactions at June 30, 2020, include ratings 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 our 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 they are incurred on each scheduled payment date, but only pays principal shortfalls upon the earlier of (i) the date on which the assets designated to fund the referenced obligation have been disposed of and (ii) the legal final maturity date of the referenced obligation.
Ambac maintains internal credit ratings on its guaranteed obligations, including credit derivative contracts, solely to indicate management’s view of the underlying credit quality of the guaranteed obligations. The gross principal notional outstanding for credit derivate contracts was $281 and $280 as of June 30, 2020 and December 31, 2019, respectively, all of which had internal Ambac ratings of AA in both periods.
Interest Rate Derivatives:
Ambac, through its subsidiary Ambac Financial Services (“AFS”), uses interest rate swaps, US Treasury futures contracts, and other derivatives, to provide a partial economic hedge against the effects of rising interest rates elsewhere in the Company, including on Ambac’s financial guarantee exposures. Additionally, AFS provided interest rate swaps to states, municipalities and their authorities, asset-backed issuers and other entities in connection with their financings. As of June 30, 2020 and December 31, 2019 the notional amounts of AFS’s derivatives are as follows:

|  | Notional

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 predetermined threshold levels. Additionally, given that Ambac

Assurance is no longer rated by an independent rating agency, counterparties have the right to terminate the swap positions.
As of June 30, 2020 and December 31, 2019, the net liability fair value of derivative instruments with contingent features linked to Ambac’s own credit risk was $132 and $89, respectively, related to which Ambac had posted cash and securities as collateral with a fair value of $152 and $109, 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 on June 30, 2020, 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. 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:

Jurisdiction | Tax Year
United States | 2010
New York State | 2013
New York City | 2015
United Kingdom | 2016
Italy | 2015

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 the deferred tax operating assets and therefore maintains a full valuation allowance.
Consolidated Pretax Income (Loss)
U.S. and foreign components of pre-tax income (loss) were as follows:

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 AFG 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.
NOL Usage Table

NOL Usage Tier | Allocated NOLs |  | Applicable Percentage
A | The first | $479 |  | 15%
B | The next | $1,057 | after Tier A | 40%
C | The next | $1,057 | after Tier B | 10%
D | The next | $1,057 | after Tier C | 15%

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 six months ended June 30, 2020, Ambac Assurance generated NOLs of approximately $143 and $137, 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 six months ended June 30, 2020, of approximately $138, 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, AFG 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. AFG 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. OCI has indicated that it will consider a number of factors, including asset quality and loss and reserve trends when considering whether or not to consent to the 2017 tax tolling payment. 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 June 30, 2020, the remaining balance of the $3,650 NOL allocated to Ambac Assurance, and new NOLs accrued during 2019 and 2020, totaled approximately $2,423. As of June 30, 2020, the consolidated group's NOL was approximately $3,674, of which Ambac's NOL was approximately $1,251.
11. COMMITMENTS AND CONTINGENCIES
The following commitments and contingencies provide an update of those discussed in Note 17: Commitments and Contingencies 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, and should be read in conjunction with the complete descriptions provided in the aforementioned Form 10-K.
Litigation Against Ambac
Financial Oversight and Management Board for Puerto Rico, et al. v. Autonomy Master Fund Limited, et al. (United States District Court, District of Puerto Rico, No. 19-ap-00291, filed May 2, 2019). On May 2, 2019, the Financial Oversight and Management Board for Puerto Rico (the "Oversight Board"), together with the Official Committee of Unsecured Creditors for the Commonwealth (the "Committee") filed an adversary proceeding against certain parties that filed proofs of claim on account of general obligation bonds issued by the Commonwealth of Puerto Rico, including Ambac Assurance. The complaint seeks declarations that the general obligation bonds are unsecured obligations and, in the alternative, seeks to avoid any security interests that holders of such bonds may have. On June 12, 2019, a group of general obligation bondholders moved to dismiss the complaint. On June 13, 2019, at the request of the Plaintiffs, the District Court stayed the case until September 1, 2019 as to all defendants; on July 24, 2019, the District Court referred this matter to mediation and ordered it stayed during the pendency of such mediation. Ambac Assurance filed a statement of position and reservation of rights on February 5, 2020; certain other defendants filed motions to dismiss on this same date. On February 9, 2020, the Oversight Board announced that it intends to file, and to seek to confirm, an amended plan of adjustment (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.
Financial Oversight and Management Board for Puerto Rico v. Ambac Assurance Corp., et al. (United States District Court, District of Puerto Rico, No. 20-ap-00003, filed Jan. 16, 2020). Pursuant to an order of the District Court setting out an agreed schedule for litigation submitted by the team of mediators designated in the
Commonwealth’s restructuring cases (the “Mediation Team“), on January 16, 2020, the Oversight Board filed an adversary proceeding against monoline insurers insuring bonds issued by the Puerto Rico Infrastructure Financing Authority (“PRIFA”) and the PRIFA bond trustee, all of which Defendants filed proofs of claim against the Commonwealth relating to PRIFA bonds. The complaint seeks to disallow Defendants’ proofs of claim against the Commonwealth in their entirety, including for lack of secured status. Briefing on motions for summary judgment is expected to conclude on August 31, 2020, and a hearing is scheduled for September 23, 2020.
Financial Oversight and Management Board for Puerto Rico v. Ambac Assurance Corp., et al. (United States District Court, District of Puerto Rico, No. 20-ap-00004, filed Jan. 16, 2020). Pursuant to an order of the District Court setting out an agreed schedule for litigation submitted by the Mediation Team, on January 16, 2020, the Oversight Board filed an adversary proceeding against monoline insurers insuring bonds issued by the Puerto Rico Convention Center District Authority (“PRCCDA”) and the PRCCDA bond trustee, all of which Defendants filed proofs of claim against the Commonwealth relating to PRCCDA bonds. The complaint seeks to disallow Defendants’ proofs of claim against the Commonwealth in their entirety, including for lack of secured status. Briefing on motions for summary judgment is expected to conclude on August 31, 2020, and a hearing is scheduled for September 23, 2020.
Financial Oversight and Management Board for Puerto Rico v. Ambac Assurance Corp., et al. (United States District Court, District of Puerto Rico, No. 20-ap-00005, filed Jan. 16, 2020).

The complaint seeks to disallow Defendants’ proofs of claim against the Commonwealth in their entirety, including for lack of secured status. Briefing on motions for summary judgment is expected to conclude on August 31, 2020, and a hearing is scheduled for September 23, 2020.
Financial Oversight and Management Board for Puerto Rico v. Ambac Assurance Corp., et al. (United States District Court, District of Puerto Rico, No. 20-ap-00007, filed Jan. 16, 2020). Pursuant to an order of the District Court setting out an agreed schedule for litigation submitted by the Mediation Team, on January 16, 2020, the Oversight Board and the Committee filed an adversary proceeding against monoline insurers insuring bonds issued by PRHTA, certain PRHTA bondholders, and the PRHTA fiscal agent for bondholders, all of which Defendants filed proofs of claim against PRHTA relating to PRHTA bonds.

Collegiate Student Loan Trusts (the “Trusts”) against Wilmington Trust Company, the Owner Trustee for the Trusts; U.S. Bank National Association, the Indenture Trustee; GSS Data Services, Inc., the Administrator; and Ambac Assurance. Through this action, Plaintiffs seek a number of judicial determinations. On January 21, 2020, the presiding Vice Chancellor entered an order consolidating the action with previously filed litigation relating to the Trusts. On February 13, 2020, Ambac Assurance, the Owner Trustee, the Indenture Trustee, and other parties filed declaratory judgment counterclaims. Several parties, including Plaintiffs and Ambac Assurance, have filed motions for judgment on the pleadings in support of their requested judicial determinations, and briefing on those motions is complete.
Ambac Assurance’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 Assurance has periodically received various regulatory inquiries and requests for information with respect to investigations and inquiries that such regulators are conducting. Ambac Assurance 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.
In re Financial Oversight and Management Board for Puerto Rico (United States District Court, District of Puerto Rico, No. 1:17-bk-03283), Omnibus Objection of (I) Financial Oversight and Management Board, Acting Through its Special Claims Committee, and (II) Official Committee of Unsecured Creditors, Pursuant to Bankruptcy Code Section 502 and Bankruptcy Rule 3007, to Claims Filed or Asserted by Holders of Certain Commonwealth General Obligation Bonds (Dkt.

Bond Claim Objection Procedures”). On January 14, 2019, the Oversight Board and the Committee filed an omnibus claim 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 March 10, 2020, the District Court ordered that this matter remain stayed while the Oversight Board attempts to confirm the Amended POA.
In re Financial Oversight and Management Board for Puerto Rico (United States District Court, District of Puerto Rico, No. 1:17-bk-03283), Ambac Assurance Corporation’s Motion to Strike Certain Provisions of the Plan Support Agreement By and Among the Financial Oversight and Management Board for Puerto Rico, Certain GO Holders, and Certain PBA Holders (Dkt. No. 13573, filed July 7, 2020) (“Amended Motion to Strike PSA”). 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. On July 16, 2019, Ambac Assurance filed a motion to strike certain provisions of the PSA that it believes violate PROMESA, including the potential payment of a breakup fee to creditors who have supported the PSA (Dkt. No. 8020) (Original Motion to Strike PSA). On February 9, 2020, the Oversight Board executed the New PSA and on March 10, 2020, the District Court denied the Original Motion to Strike PSA without prejudice given the execution of the New PSA. On July 7, 2020, Ambac Assurance filed the Amended Motion to Strike PSA seeking similar relief with respect to the New PSA. Briefing on the Amended Motion to Strike PSA is expected to conclude on September 8, 2020.
In re Financial Oversight and Management Board for Puerto Rico (United States District Court, District of Puerto Rico, No. 1:17-bk-03283), Ambac Assurance Corporation's Motion and Memorandum of Law in Support of Its Motion Concerning Application of the Automatic Stay to the Revenues Securing PRIFA Rum Tax Bonds (Dkt. No. 7176, filed May 30, 2019) (“PRIFA Stay
Motion”). On May 30, 2019, Ambac Assurance filed a motion seeking an order that the automatic stay does not apply to certain lawsuits Ambac Assurance seeks to bring or to continue relating to bonds issued by PRIFA, or, in the alternative, for relief from the automatic stay to pursue such lawsuits or for adequate protection of Ambac Assurance's collateral. On July 24, 2019, the District Court referred this matter to mediation and ordered it stayed during the pendency of such mediation. On January 31, 2020, the District Court granted a motion filed by Ambac Assurance, together with Assured Guaranty Corporation, Assured Guaranty Municipal Corporation, and Financial Guaranty Insurance Company to amend the PRIFA Stay Motion in order to allow the PRIFA bond trustee to join the amended motion and to allow movants to address recent, controlling precedent from the First Circuit, and Ambac Assurance filed the amended motion the same day. On July 2, 2020, the Court denied the motion to lift the stay on certain grounds. Briefing regarding additional grounds on which Ambac Assurance and other movants seek stay relief concluded on August 5, 2020.

Ambac Assurance Corporation v. Merrill Lynch, Pierce, Fenner & Smith Incorporated, Goldman Sachs & Co. LLC, Citigroup Global Markets Inc., J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, Samuel A. Ramirez & Co. Inc., Raymond James & Associates, Inc., and UBS Financial Services Inc. (Commonwealth of Puerto Rico, Court of First Instance, San Juan Superior Court, Case No. CV-000248923, filed February 19, 2020). On February 19, 2020, Ambac Assurance filed a complaint in the Commonwealth of Puerto Rico, Court of First Instance, San Juan Superior Court, against certain underwriters of Ambac-insured bonds issued by PRIFA and PRCCDA, with causes of action under the Puerto Rico civil law doctrines of actos proprios and Unilateral Declaration of Will. Ambac Assurance alleges defendants engaged in inequitable conduct in underwriting Ambac-insured bonds issued by PRIFA and PRCCDA, including failing to investigate and adequately disclose material information in the official statements for the bonds that defendants provided to Ambac Assurance regarding systemic deficiencies in the Commonwealth’s financial reporting. Ambac Assurance seeks damages in compensation for claims paid by Ambac Assurance on its financial guaranty insurance policies insuring such bonds, pre-judgment and post-judgment interest, and attorneys’ fees. On March 20, 2020, Defendants removed this case to the Title III Court. On April 20, 2020, Ambac moved to remand the case back to the Court of First Instance. Briefing on the motion to remand concluded on June 10, 2020.
Ambac Assurance Corporation v. Autopistas Metropolitanas de Puerto Rico, LLC (United States District Court, District of Puerto Rico, No. 3:20-cv-01094, filed February 19, 2020). On February 19, 2020, Ambac Assurance filed a complaint in the U.S. District Court for the District of Puerto Rico, against Autopistas Metropolitanas de Puerto Rico, LLC (“Metropistas”), which holds a concession from PRHTA for two Puerto Rico highways, PR-5 and PR-22, in connection with a 10-year extension of the concession that was entered into in April 2016. The complaint includes claims for fraudulent conveyance and unjust enrichment, alleging that the consideration paid by Metropistas for the extension was less than reasonably equivalent value and most of the benefit of such payment was received by the Commonwealth instead of PRHTA. Ambac Assurance also seeks a declaratory judgment that it has a valid and continuing lien on certain toll revenues that are being collected by Metropistas. On March 31, 2020, the Oversight Board filed a motion before the Title III Court seeking an order directing Ambac to withdraw its complaint. On April 20, 2020, the District Court ordered this case stayed pending briefing before the Title III Court on the Oversight Board’s motion to withdraw. On June 16, 2020, the Title III Court ordered Ambac Assurance to withdraw its complaint.

Bankruptcy Clause of the U.S. Constitution (which requires all bankruptcy laws to be uniform) and (ii) dismissal of the pending Title III petitions. Defendants’ answer or other response to the adversary complaint is due on August 17, 2020.
Student Loans Exposure
CFPB v. Nat’l Collegiate Master Student Loan Trust (United States District Court, District of Delaware, Case No. 1:17-cv-01323, filed September 18, 2017). The Consumer Financial Protection Bureau (“CFPB”) filed a complaint against fifteen National Collegiate Student Loan Trusts, regarding alleged improprieties and deficiencies in servicing practices. Simultaneous with the filing of its complaint, CFPB also filed a motion to approve a proposed consent judgment that would have granted monetary damages and injunctive relief against the Trusts. Ambac Assurance guaranteed certain securities issued by three of the Trusts and indirectly insures six other Trusts. On September 20, 2017, Ambac Assurance filed a motion to intervene in the action, which motion was granted on October 19, 2018. Following discovery and briefing, on May 31, 2020, the District Court denied the CFPB’s motion to approve the proposed consent judgment.
On March 19, 2020, Intervenor Transworld Systems Inc. filed a motion to dismiss the action for lack of subject matter jurisdiction. On July 10, 2020, Ambac Assurance and several other intervenors filed a motion to dismiss the action for lack of subject matter jurisdiction and for failure to state a claim. Both motions to dismiss will be fully briefed on August 28, 2020. Additionally, on July 2, 2020, the CFPB submitted an application for entry of default against the Trusts. Ambac Assurance and the Owner Trustee opposed the CFPB’s application, which remains pending.
RMBS Litigation
In connection with Ambac Assurance’s efforts to seek redress for breaches of representations and warranties and fraud related to the information provided by both the underwriters and the sponsors of various transactions and for failure to comply with the obligation by the sponsors to repurchase ineligible loans, Ambac Assurance has filed various lawsuits:

• | Ambac Assurance Corporation and The Segregated Account of Ambac Assurance Corporation v. Countrywide Securities Corp., Countrywide Financial Corp. (a.k.a. Bank of America Home Loans) and Bank of America Corp. (Supreme Court of the State of New York, County of New York, Case No. 651612/2010, filed on September 28, 2010). Ambac Assurance’s Second Amended Complaint, filed on May 28, 2013, asserted claims against Countrywide and Bank of America (as successor to Countrywide’s liabilities) for, among other things, breach of contract and fraudulent inducement. In August and October 2018, Defendants filed various pre-trial motions. On December 30, 2018, the court denied all of these pre-trial motions in their entirety and Defendants appealed. On September 17, 2019, the First Department affirmed in part and reversed in part the trial court’s rulings. On October 17, 2019, Countrywide filed a motion for leave to appeal certain issues to the New York Court of Appeals and for reargument or leave to appeal certain other issues. On January 16, 2020, the First Department recalled and vacated its September 17, 2019 decision and order and substituted a new decision and order.

On the same date, the First Department denied Countrywide’s motion seeking leave to appeal, without prejudice to seeking such leave from the reissued decision and order. On January 30, 2020, Countrywide filed a new motion for leave to appeal the First Department’s denial of its motions, which Ambac Assurance opposed. On June 11, 2020, the First Department denied Countrywide’s motion for leave to appeal. On January 14, 2020, the trial court granted Ambac Assurance’s motion to supplement and amend certain of its expert reports, and expert discovery is ongoing. On June 25, 2020, the trial court scheduled trial to commence on February 22, 2021 (which could be rescheduled if the COVID-19 pandemic prevents the court system from holding jury trials or there are other intervening causes of delay).

• | Ambac Assurance Corporation v. U.S. Bank National Association (United States District Court, Southern District of New York, Docket No. 18-cv-5182 (LGS), filed June 8, 2018 (the “SDNY Action”)); In the matter of HarborView Mortgage Loan Trust 2005-10 (Minnesota state court, Docket No. 27-TR-CV-17-32 (the “Minnesota Action”)). These two actions relate to U.S. Bank National Association’s (“U.S. Bank”) acceptance of a proposed settlement in a separate litigation that U.S. Bank is prosecuting, as trustee, related to the Harborview Mortgage Loan Trust, Series 2005-10 (“Harborview 2005-10”), a residential mortgage-backed securitization for which Ambac Assurance issued an insurance policy. On March 6, 2017, U.S. Bank filed a petition commencing the Minnesota Action, a trust instruction proceeding in Minnesota state court concerning the proposed settlement, and on June 12, 2017, U.S. Bank filed an amended petition. Ambac Assurance filed a motion to dismiss the Minnesota Action, which was denied on November 13, 2017, and the denial was affirmed on appeal. On September 6, 2018, U.S. Bank filed its Second Amended Petition, and Ambac Assurance and certain other certificateholders objected to, or otherwise responded to, the petition. Discovery in the Minnesota Action is ongoing, and the court has set October 14, 2020 as the date for the start of the trial. On June 8, 2018, Ambac Assurance filed the SDNY Action asserting claims arising out of U.S. Bank’s acceptance of the proposed settlement and treatment of trust recoveries. Ambac Assurance asserted claims for declaratory judgment, breach of contract, and breach of fiduciary duty. On July 16, 2019, the court dismissed Ambac Assurance's breach-of-contract and breach-of-fiduciary-duty claims based on U.S. Bank's acceptance of the settlement; and dismissed Ambac Assurance's declaratory judgment claims regarding the occurrence of an Event of Default and U.S. Bank's future distribution of trust recoveries through the waterfall. The court denied the motion to dismiss Ambac Assurance's breach-of-contract claims based on U.S. Bank's past distribution of trust recoveries through the waterfall. On January 17, 2020, U.S. Bank moved for summary judgment regarding the remaining claim relating to distributions. On February 7, 2020, Ambac Assurance cross-moved for summary judgment. These summary judgment motions are fully briefed.

• | In re application of Deutsche Bank National Trust Company as Trustee of the Harborview Mortgage Loan Trust Mortgage Loan Pass-Through Certificates, Series 2006-9 (Supreme Court of the State of New York, County of New York, No. 654208/2018), filed August 23, 2018 (the “Trust Instruction

Proceeding”). This action relates to Deutsche Bank National Trust Company’s (“DBNT”) proposed settlement of claims related to the Harborview Mortgage Loan Trust Series 2006-9 (“Harborview 2006-9”). On August 23, 2018, DBNT filed a Petition commencing the Trust Instruction Proceeding, seeking judicial instruction pursuant to CPLR Article 77, inter alia, to accept the proposed settlement with respect of claims relating to Harborview 2006-9. On November 2, 2018, Ambac Assurance and other interested persons filed notices of intention to appear and answers to DBNT’s petition. Ambac Assurance sought a period of discovery before resolution on the merits. Under the current case schedule discovery is to be completed by August 20, 2020 and merits briefing by October 19, 2020.

Item 2. | Management’s Discussion and Analysis of Financial Condition and Results of Operations

Following this summary is a discussion addressing the consolidated results of operations and financial condition of Ambac Financial Group, Inc. (“AFG”) for the periods indicated. References to “Ambac,” the “Company,” “we,” “our,” and “us” are to AFG and its subsidiaries, as the context requires. This discussion should be read in conjunction with Ambac’s Annual Report on Form 10-K for the year ended December 31, 2019, the Cautionary Statement Pursuant To The Private Securities Litigation Reform Act Of 1995 below and Risk Factors set forth in Part II, Item 1A of this Form 10-Q and in Ambac’s Annual Report on Form 10-K for the year ended December 31, 2019.
This Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) contains certain financial measures, in particular the presentation of Adjusted Earnings and Adjusted Book Value, which are not presented in accordance with U.S. generally accepted accounting principles (“GAAP”). We are presenting these non-GAAP financial measures because they provide greater transparency and enhanced visibility into the underlying drivers of our business. We do not intend for these non-GAAP financial measures to be a substitute for any GAAP financial measure and they may differ from similar reporting provided by other companies. Readers of this Form 10-Q should use these non-GAAP financial measures only in conjunction with the comparable GAAP financial measures. Adjusted Earnings and Adjusted Book Value are non-GAAP financial measures that adjust for the impact of certain non-recurring or non-economic GAAP accounting requirements and include the addition of certain items that the Company has or expects to realize in the future, but that are not reported under GAAP. We provide reconciliations to the most directly comparable GAAP measures; Adjusted Earnings to Net income attributable to common stockholders and Adjusted Book Value to Total Ambac Financial Group, Inc. stockholders’ equity.

EXECUTIVE SUMMARY
Company Overview:
See Note 1. Background and Business Description to the Unaudited Consolidated Financial Statements, included in Part I, Item 1 in this Form 10-Q and Note 1. Background and Business Description
| Ambac Financial Group, Inc. 47 2020 Second Quarter FORM 10-Q |

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, for a description of the Company and our key strategic priorities to achieve our primary goal to maximize stockholder value.
Ambac Assurance and Subsidiaries:
A key strategy for Ambac is to increase the value of its investment in Ambac Assurance by actively managing its assets and liabilities. Asset management primarily entails maximizing the risk 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:
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. The investment portfolios of Ambac Assurance and Ambac UK hold fixed income securities, including distressed Ambac-insured securities, and various pooled investment funds. Refer to Note 8. Investments to the Unaudited Consolidated Financial Statements, included in Part I, Item 1 in this Form 10-Q for further details of fixed income investments by asset category and pooled investment funds by investment type.
At June 30, 2020, Ambac and its subsidiaries owned $574 million of distressed Ambac-insured bonds, including significant concentrations of insured Puerto Rico and RMBS bonds, and excluding Ambac's holdings of secured notes issued by Ambac LSNI. Subject to applicable internal and regulatory guidelines, market conditions and other constraints, Ambac may continue to opportunistically purchase or sell Ambac-insured securities.
Liability and Insured Exposure Management:
Ambac Assurance's Risk Management Group focuses on the implementation and execution of risk reduction, 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, successful risk reduction transactions included:

• | A commutation in January 2020, via a refunding, of a watch list public finance transaction with net par outstanding of $171 million at December 31, 2019;

• | A refinancing in February 2020 of an adversely classified asset-backed leasing transaction with net par outstanding of $86 million at December 31, 2019; and

• | Purchasing quota share reinsurance in June 2020 on a transportation revenue credit with net par outstanding of $33 million at December 31, 2019.

The following table provides a comparison of total, adversely classified ("ACC") and watch list credit net par outstanding in the insured portfolio at June 30, 2020 and December 31, 2019. Net par exposure within the U.S. public finance market includes capital
appreciation bonds which are reported at the par amount at the time of issuance of the insurance policy as opposed to the current accreted value of the bonds.

($ in millions) | June 30, 2020 |  | December 31, 2019 |  | Variance
Total | $ | 35,276 |  |  | $ | 38,018 |  |  | $ | (2,742 | ) |  | (7 | )%
ACC | 8,756 |  |  | 7,535 |  |  | 1,221 |  |  | 16 | %
Watch list | 5,238 |  |  | 6,752 |  |  | (1,514 | ) |  | (22 | )%

The decrease in total net par outstanding resulted from active de-risking initiatives, including the transactions noted above, as well as scheduled maturities, amortizations, refundings and calls. Additionally, total net par outstanding reduced as a result of the weakening of British Pounds as compared to US Dollars.
The increase in ACC exposures is primarily due to the addition of credits impacted by COVID-19 (including $1,002 million of net par outstanding from the Watch List category), such as hotel tax, stadium, convention center and public house insured transactions, partially offset by active de-risking and paydowns or calls by issuers.
The decrease in Watch List net par outstanding resulted from active de-risking initiatives, including the transactions noted above, $970 million of net par outstanding downgraded to ACC due to COVID-19, as well as scheduled maturities, amortizations, refundings and calls.
In addition, as a result of the economic impacts from the COVID-19 pandemic, $2,686 million of net par outstanding in sectors such as mass transit, toll roads, and private higher education, among others, have been added to the Survey List. The Survey List is a categorization for enhanced monitoring of currently performing credits.
We continue to experience stress in our exposure to Puerto Rico that consists of several different issuing entities (all below investment grade). Each issuing entity has its own credit risk profile attributable to discreet revenue sources, direct general obligation pledges and general obligation guarantees. Refer to Part 1, Item 1 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, for additional information regarding the different issuing entities that encompass Ambac's exposures to Puerto Rico.
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 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 conditions, including but not limited to higher unemployment; a broad based and significant decrease in asset valuations; 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. While many states eased restrictions during the later portion of the second quarter of 2020,
| Ambac Financial Group, Inc. 48 2020 Second Quarter FORM 10-Q |

various U.S. States reversed course in late June to impose or reimpose social distancing guidelines and close down businesses that had begun opening as a result of a rise in new confirmed cases of COVID-19, raising the prospect of a delayed recovery.
In addition, in March 2020 a disagreement between Russia and Saudi Arabia over oil production quotas coupled with lower global demand as a result of the COVID-19 crisis led to volatility and overall lower oil prices which continued through the second quarter of 2020.
In the U.S., monetary policy and fiscal stimulus, particularly the Coronavirus Aid, Relief and Economic Security ("CARES") Act, have temporarily helped moderate the economic impact of COVID-19, along with stimulus and other actions taken by governments outside the U.S.
Nonetheless, the U.S. and most large global economies materially contracted through the second quarter of the year. While a recovery is currently underway led by a sharp increase in retail sales in North America and the Eurozone in May and June, the trajectory and sustainability of the economic recovery is uncertain due to, among other things, the magnitude of job losses, the uncertainty or scaling back of government support measures and the rise of new COVID-19 cases in the U.S. For the Ambac insured portfolio, credit risk continues to remain elevated due to the uncertain economic recovery from the COVID-19 crisis.
COVID-19 has also impacted Ambac's operating environment. Ambac has implemented a COVID-19 response plan designed to ensure the safety of our staff and business continuity. Our employees have transitioned to working remotely while maintaining full operational capabilities. In July 2020, Ambac opened certain of its offices to allow a portion of the workforce to safely return on a voluntary basis. We have not experienced and do not anticipate incurring material net incremental operating expenditures to maintain the current operating environment. In addition to our own staff, Ambac's critical third-party service providers are operating remotely 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 provided in the current circumstances. Ambac does not believe that our current operating environment has resulted in a significant change to our disclosure controls or internal controls over financial reporting.
COVID-19 has adversely impacted Ambac's financial position and results of operations as credit risk in the insured and investment portfolios has increased. The municipal, project finance, mortgage-backed and student loan sectors, as well as other asset securitizations, in particular, could be materially adversely impacted, and as a result, with the exception of the mortgage-backed sector, we have increased loss reserves across each of these and other sectors during the six months ended June 30, 2020. In the mortgage-backed sector, much lower interest rates have increased excess spread recoveries on previously paid claims and largely offset the impact of higher projected mortgage delinquencies and losses resulting from the COVID-19 pandemic. 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
ability of issuers of insured obligations and other counterparties to pay their obligations when due, whether due to operational or financial reasons; (ii) the impact of changes to interest rates on policy and derivative payments; 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 impact on issuers and markets where Ambac provides financial 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 and may further increase them in the future depending on the duration and severity of the crisis. The crisis may also impair certain issuers' ability to pay premiums owed to Ambac; however, we believe such issuers currently have the ability to continue to pay such premiums timely, but this is subject to change.

• | Ambac has exposure to reinsurance counterparties for their portions of future claim payments. Ambac has reinsured approximately 13.5% of its gross par outstanding to four 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 currently believes they have the ability to perform under their respective reinsurance policies, but this is subject to change.

• | Ambac is exposed to the risk that contractual counterparties (including those under our RMBS litigations and derivative counterparties) may default in 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 this is subject to change.

• | Asset prices declined substantially during the first 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 monetized 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 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. Asset prices partially recovered during the second quarter of 2020. Ambac recognized a total return for the investment portfolio of approximately 4.7% during the three months ended June 30, 2020.

| Ambac Financial Group, Inc. 49 2020 Second Quarter FORM 10-Q |

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," "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.
AFG:
As of June 30, 2020 the net assets of AFG were $481 million.

(1) | A portion of Ambac UK's, and to a lesser extent Ambac Assurance's, assets and liabilities are denominated in currencies other than its functional currency and accordingly, we recognized net foreign currency transaction gains/(losses) as a result of changes to foreign currency rates through our Unaudited Consolidated Statement of Total Comprehensive Income (Loss). Refer to Note 2. Basis of Presentation and Significant Accounting Policies to the Unaudited

Consolidated Financial Statements included in Part I, Item 1 in this Form 10-Q for further details on transaction gains and losses.
Future changes to currency rates may adversely affect our financial results. Refer to Part II, Item 7A in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, for further information on the impact of future currency rate changes on Ambac's financial instruments.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Ambac’s Unaudited Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), which require the use of material estimates and assumptions. For a discussion of Ambac’s critical accounting policies and estimates, see “Critical Accounting Policies and Estimates” 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.
FINANCIAL GUARANTEES IN FORCE
Financial guarantee products were sold in three principal markets: U.S. public finance, U.S. structured finance and international finance. The following table provides a breakdown of guaranteed net par outstanding by market at June 30, 2020 and December 31, 2019. Net par exposures within the U.S. public finance market include capital appreciation bonds which are reported at the par amount at the time of issuance of the insurance policy as opposed to the current accreted value of the bonds. Guaranteed net par outstanding includes the exposures of policies insuring variable interest entities (“VIEs”) consolidated in accordance with the Consolidation Topic of the ASC. Guaranteed net par outstanding excludes the exposures of policies that insure bonds which have been refunded or pre-refunded and excludes exposure of the policy that insures the notes issued by Ambac LSNI as defined in Note 1.

(1) | Internal credit ratings are provided solely to indicate the underlying credit quality of guaranteed obligations based on the view of Ambac. In cases where Ambac has insured multiple tranches of an issue with varying internal ratings, or more than one obligation of an issuer with varying internal ratings, a weighted average rating is used. Ambac credit ratings are subject to revision at any time and do not constitute investment advice. BIG denotes credits deemed below investment grade.

(2) | Net Par includes capital appreciation bonds, which are reported at the par amount at the time of issuance of the insurance policy as opposed to the current accreted value of the bonds.

(3) | A portion of this transaction is insured by an insurance policy issued by Ambac Assurance. Ambac Assurance has issued policies for these transactions that will only pay in the event that Ambac UK does not pay under its insurance policies ("second to pay policies").

Net par related to the top ten exposures reduced $392 from December 31, 2019. Exposures are impacted by changes in foreign exchange rates, certain indexation rates and scheduled and unscheduled paydowns. The decrease from 2019 was primarily related to foreign exchange and scheduled paydowns. The concentration of net par amongst the top ten (as a percentage of net par outstanding) increased slightly to 21% at June 30, 2020, from 20% at December 31, 2019. However, certain credits within the top ten have had Ambac rating downgrades since December 31, 2019, primarily related to the impact of COVID-19, including Mitchells & Butlers Finance plc, New Jersey Transportation Trust Fund Authority and Mets Queens Baseball Stadium Project. Aspire Defence Finance plc's rating at June 30, 2020, improved since December 31, 2019. The remaining insured portfolio of financial guarantees has an average net par outstanding of $32 million per single risk, with insured exposures ranging up to $492 million and a median net par outstanding of $6 million.
Given that Ambac has not written any new insurance policies since 2008, the risk exists that the insured portfolio becomes increasingly concentrated to large and/or below investment grade exposures.
COVID-19
COVID-19 and the public health responses by the US federal and state governments have shut down 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, have implemented similar measures to the US. Ambac has undertaken a detailed analysis of the potential impact of the closure of certain portions of the US economy and certain other economies, including the UK, Italy, and Australia, to assess the impact of the current global economic contraction on its insured financial guarantee portfolio. The duration and depth of the economic contraction; actions such as monetary policy and fiscal stimulus, including the CARES Act in the US that was signed into law on March 27, 2020, and future fiscal stimulus programs; and our insured obligors' financial flexibility and ability to mitigate the
operational and economic impact of the recession will determine the ultimate impact to Ambac's insured portfolio.
CARES Act and Other Relief Measures:
The $2.4 trillion Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") provides relief and stimulus funds for American consumers, businesses and industries impacted by COVID-19.
The CARES Act has several measures that impacted US municipalities and other borrowers, including consumers, such as mortgage and student loan borrowers, represented in our insured portfolio, including:

• | A program for direct lending, loans, loan guarantees and investments to eligible businesses, states and municipalities, including to passenger airlines and cargo airlines;

| Ambac Financial Group, Inc. 51 2020 Second Quarter FORM 10-Q |

• | A program for small business loans (Paycheck Protection Program, as amended by the Paycheck Protection Program and Health Care Enhancement Act (“PPP & HCE Act”));

• | Business tax breaks, including payroll tax deferral

• | An allocation of direct aid to state and local governments to reimburse them for the costs of dealing with COVID-19;

• | The Public Health and Social Services Fund for distribution of grants to healthcare providers and hospitals (as amended by the PPP & HCE Act);

• | Grants for transit agencies;

• | Grants for airport authorities; and

• | Direct payments to households and for unemployment insurance.

Despite the above provisions, which are designed to help mitigate the economic impact of the COVID-19 pandemic generally, the CARES Act contains certain provisions that 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 the CARES Act provision did not include 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 have elected not to pay altogether. Despite the assumed increase in delinquencies and losses related to this 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, the federal government has provided 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 moratoriums on foreclosures and evictions as 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 guidance to mortgage loan servicers concerning loan forbearances and other relief for borrowers. Depending 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's insured RMBS obligations are unclear, 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 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

• | $100 billion in loans for the Term Asset-backed Securities Facility

In the UK all non-essential leisure, food and retail operations, including public houses were closed from March 20, 2020 as a consequence of the COVID-19 pandemic. Premises were allowed to gradually reopen from June 1, 2020 such that by July 4, 2020 the majority of outlets were permitted to reopen. The UK Government introduced a number of 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. These measures are slowly being withdrawn between August 1, 2020 and the end of the year.
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 COVID-19 pandemic remains elevated, and we could experience material losses that would adversely impact our future results of operations and financial condition.
Insured Portfolio:
Ambac established a set of base case assumptions that includes a deep recession during the first half of 2020 with a modest recovery in the second half of 2020 that still leaves the U.S. with an overall contraction in GDP for the full year. Economic growth for 2021, while positive, is expected to be tempered by the continued uncertainty related to the rising infection rate of COVID-19 in the U.S. Recovery to 2019 levels of economic output are not expected until 2022. Consequently, we expect pressure will remain on U.S. states and local governments which are currently facing significant budget deficits as tax revenues have faltered as a result of COVID-19 related shutdowns, job losses and travel restrictions. State and local governments have shed an estimated 1.5 million jobs and are facing tough choices to close budget gaps, including tax increases, furloughs, public safety cuts, planned capital expenditure cuts, pension funding holidays, and other measures. In addition states may need cut aid to local municipalities that are also under pressure from lost revenues. Monetary policy and federal stimulus through the CARES Act (and potential subsequent CARES Act programs) and other programs has benefited and is expected to continue to benefit in the overall economic recovery and more specifically provide some relief to state and local governments, including to issuers of municipal debt insured by Ambac, although the sufficiency of such benefits remains uncertain.
| Ambac Financial Group, Inc. 52 2020 Second Quarter FORM 10-Q |

As part of the 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 or uneven recovery from the COVID-19 crisis. 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 stressed although several issuers expressed a willingness to use their balance sheets to support their obligations and avoid defaults in the near-term. Ambac's insured par outstanding, net of reinsurance ("NPO"), to these Public Finance sectors are as follows:

($ in millions) Market / Sector | Total NPO | Total Debt Service Due Next Twelve Months
Hotels / Convention Centers | $ | 257 |  | $ | 37.3 |
Stadiums | 634 |  | 41.7 |
Airports | 124 |  | 22.0 |
Dedicated Tax | 410 |  | 78.0 |
Higher Education Auxiliary | 252 |  | 26.9 |
Rail / Mass Transit | 328 |  | 30.1 |
Toll Roads / Bridges | 469 |  | 35.8 |
Total Public Finance | $ | 2,474 |  | $ | 271.8 |

The RMBS and student loan insured portfolios are expected to be adversely impacted by the previously mentioned forbearances and the general economic downturn. Expected to offset such impact for RMBS exposures is the benefit to excess spread within the securitization structures as a result of the significant reduction in interest rates, which will result in higher recoveries.
Ambac insured exposure includes a number of international policies where the revenue of the issuer is demand dependent. Such transactions have been impacted by the reduction of revenue due to the COVID-19 pandemic. Ambac and its advisors are working closely with impacted issuers to review their plans and liquidity facilities in light of these events. Ambac's NPO with respect to these international demand dependent policies are as follows:

($ in millions) Market / Sector | Total NPO | Total Debt Service Due for Twelve Months
Stadiums | $ | 203 |  | $ | 23.6 |
Higher Education | 161 |  | 8.7 |
Airports | 192 |  | 6.0 |
Asset Securitizations | 938 |  | 78.9 |
Toll Roads / Bridges | 719 |  | 57.0 |
Total | $ | 2,213 |  | $ | 174.2 |

At this time, there are significant uncertainties surrounding the ultimate number of claims and scope of damage resulting from this pandemic. Actual losses from these events may vary materially from Ambac's loss and loss expense reserves due to several factors, including the inherent uncertainties in making such determinations and the evolving nature of this pandemic. Potential losses from the economic consequences of the COVID-19 pandemic could be material and therefore may have a material adverse effect on our results of operations and financial condition.
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 as of June 30, 2020. Each has its own credit risk profile attributable to, as applicable, discrete revenue sources, direct general obligation pledges and/or general obligation guarantees.
COVID-19
At this time, it remains very difficult to predict what the shape and timing of the post COVID-19 recovery will be for the Commonwealth of Puerto Rico, not least because the depth and length of COVID-19's impact is still uncertain. In the short-term, it is known that tax revenue to the Commonwealth’s general fund collections lagged projections by nearly $1.8 billion, or 16.8%, in fiscal year 2020 and were roughly $2.5 billion below fiscal year 2019 collections, according to the Puerto Rico Fiscal Agency and Financial Advisory Authority’s Treasury Single Account report, which is as of June 26, 2020. General fund collections slowed due to the COVID-19 outbreak and imposed lockdown. Separately, Puerto Rico Highways and Transportation Authority's ("PRHTA") total consolidated fiscal year 2020 revenues were $404.3 million, 36.3% lower than the $634.8 million budget projection. The underperformance was due to a variety of factors including a reduction in the traffic and toll collections due to COVID-19.
Over the longer-term, Puerto Rico's recovery profile will be impacted by a wide range of factors including, but not limited to:

• | t he fiscal and monetary policies of the federal government which will shape the trajectory of the U.S. economy;

• | the speed and efficacy of targeted federal aid packages to (1) help Puerto Rico address the negative economic effects of the pandemic and (2) rebuild better and more resilient infrastructure post-Hurricanes Irma and Maria in 2017 and earthquakes in 2020;

• | supplemental Medicaid funding relief; and

• | the willingness and ability of the Commonwealth government to implement much needed fiscal and structural reforms.

Fiscal Plans
On May 27, 2020, the Oversight Board certified its own version of a new Commonwealth Fiscal Plan. The Oversight Board’s new Commonwealth Fiscal Plan purports to incorporate the impact of COVID-19 on the Commonwealth economy, and projects diminished growth, budget surplus, and debt capacity as compared to previous versions of the Commonwealth Fiscal Plan. The positive $19.7 billion 30-year cumulative surplus from the May 2019 Fiscal Plan is now a negative $22.2 billion in the new Fiscal Plan base case and negative $40 billion in the downside case. This is due to the Oversight Board’s projected impact of COVID-19 on the Puerto Rico economy and tax collections as well as related general uncertainty on the economic outlook. The Commonwealth Fiscal Plan will significantly inform the Commonwealth Plan of Adjustment, and the diminished economic performance described in the new Fiscal Plan implies worse outcomes than had been previously disclosed for creditors under the Commonwealth's Plan of Adjustment.
| Ambac Financial Group, Inc. 53 2020 Second Quarter FORM 10-Q |

On June 26, 2020, the Oversight Board certified its own version of the Fiscal Plan for PRHTA. The PRHTA Fiscal Plan states that based on cash flow projections, the existing PRHTA debt service will require significant restructuring and PRHTA’s full commitment to reforms. It's currently unclear what the Oversight Board's scope of debt restructuring will be. As for reforms, the PRHTA Fiscal Plan requires PRHTA to establish an independent board with experienced and knowledgeable directors, and requires six measures to improve revenue, including increases in toll fine collections, tolls, introduction of congestion pricing, and four measures to cut expenses, including reducing pension and employee healthcare costs.
It is unknown if 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. It is also unknown if and when other Puerto Rico instrumentalities, which have debt outstanding insured by Ambac Assurance, will be filed under Title III and what effect their fiscal plans and/or plans of adjustment may have on Ambac's financial position.
No assurances can be given that Ambac's financial condition will not suffer a materially negative impact as an ultimate result of the Commonwealth Fiscal Plan, the Commonwealth Plan of Adjustment, or any future changes or revisions to Commonwealth fiscal plans or future fiscal plans and/or plans of adjustment for PRHTA or other Puerto Rico instrumentalities.
Commonwealth Plan of Adjustment
On February 9, 2020, the Oversight Board announced it reached an agreement in principle ("Plan Support Agreement") with certain creditors supporting the restructuring 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 POA and an amended Disclosure Statement 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. The Amended POA would reduce Commonwealth debt and other claims from $35 billion to less than $11 billion, a 70% cut and would also reduce the Commonwealth’s annual debt service by 56%. Treatment for pension claims would include 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.
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, Puerto Rico Infrastructure Financing Authority (PRIFA) Special Tax Revenue (Rum Tax) bonds, and Puerto Rico Convention Center District Authority (PRCCDA) bonds. It is unknown if and how the Amended POA may be modified or what the final adjustments will be to the revenues available to the Puerto Rico instrumentalities addressed in the Amended POA or the recoveries on claims against the Commonwealth by creditors of those instrumentalities, including Ambac and Ambac-insured bondholders. However, if the Amended POA were confirmed in
its current form, Ambac's financial condition would suffer a material negative impact. Refer to Note 6. Financial Guarantee Insurance Contracts to the Unaudited Consolidated Financial Statements included in Part I, Item 1 in this Form 10-Q for the possible increase in loss reserves under stress or other adverse conditions, including the impact of the Amended POA. There can be no assurance that losses may not exceed such estimates.
Currently, the schedule for confirmation proceedings regarding the Amended POA, and the hearings regarding the Disclosure Statement that must precede confirmation hearings, is not yet set. However, on July 15, 2020, the Oversight Board filed a status report in Court that included a request to provide the Court with an updated status report regarding the timeline for the debtors’ Plan of Adjustment and Disclosure Statement process by September 11, 2020. Judge Swain subsequently granted the request and directed the Oversight Board to file an updated status report, including a proposal for the debtors’ Plan and Disclosure Statement process, by September 9, 2020.
Political Developments
On July 1, 2020, Oversight Board Chairman Jose Carrion and Board member Carlos Garcia announced that they informed the White House they will not be available for re-nomination to serve another three-year term on the Oversight Board. Carrion said he is stepping down by October 5, and Garcia said he is resigning his post effective August 31. In a press conference, Carrion said he knows of “at least” one additional board member who does not intend to serve an additional term but said it is not up to him to make the announcement. It is unclear how the resignations will impact the debt restructuring process, negotiations, timing and ultimate outcome for Ambac.
Governor Vazquez has recently come under fire for her termination (on July 3, 2020) of the Secretary of the Department of Justice, which was conducting various investigations into Vazquez and her advisors. The Governor’s replacement halted all such investigations and subsequently resigned on July 8, 2020 succumbing to political pressure. On July 20, 2020 it was announced that Governor Vazquez and five officials will be subject to investigation by a special independent prosecutor regarding emergency supplies management during the series of earthquakes that occurred in early 2020. Governor Vazquez may also face an investigation into recent government contracts and related procurement of COVID-19 tests. It is unclear how these investigations may affect the outcome of the August 2020 primary, where Vazquez is competing for the party gubernatorial ticket against former Resident Commissioner Pedro Pierluisi.
Ambac Title III Litigation Update
Ambac Assurance 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, Ambac Assurance filed motions which sought to lift the stay and allow Ambac and others to enforce their rights related to HTA, CCDA and PRIFA in an alternative forum. On July 2, 2020, Judge Swain issued orders denying, in large part, these motions. Supplemental briefing on the motions to lift the stay has concluded and a final decision is expected this fall. Ambac is unable to predict when and how the issues raised in these cases
| Ambac Financial Group, Inc. 54 2020 Second Quarter FORM 10-Q |

will be resolved. If Ambac Assurance 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, 2019 and Note 11. Commitments and Contingencies to the Consolidated Financial Statements, included in Part I, Item 1 of this Form 10-Q for further information about Ambac's litigation relating to Puerto Rico.
Mediation
The status, timing and subject of any subsequent or future mediation discussion has not yet been publicly disclosed. However, Judge Swain issued a scheduling order on June 15, 2020, setting monthly omnibus hearings through the end of 2021. The timeline for resolution of Puerto Rico’s debt restructuring process is uncertain but may extend into 2021.
It appears the Oversight Board will attempt to move forward with the Amended POA and Plan Support Agreement in some modified form over the intermediate term. The debt restructuring process status report the Oversight Board filed with the Court on July 15, 2020 stated, “Having completed the process of certifying the Commonwealth Fiscal Plan and corresponding Budget, the Oversight Board has resumed discussions with AAFAF concerning the terms of a Plan of Adjustment and what, if any, modifications or amendments need to be proposed to the Plan of Adjustment and Disclosure Statement filed with the Court on February 28, 2020. The Oversight Board anticipates that, in the coming weeks, the Oversight Board and AAFAF shall entertain discussions with creditors (those party to the Plan Support Agreement, as amended on March 13, 2020 and April 1, 2020, as well as other parties in interest), with the guidance of the mediation team led by the Judge Barbara J. Houser, to address the new reality created by the COVID-19 pandemic. The discussions with creditors will take into account, among other things, this Court’s July 2, 2020 decisions in connection with certain motions for relief from the automatic stay filed by holders and insurers of HTA bonds, CCDA bonds, and PRIFA Rum Tax Bonds. Furthermore, the outcome of the ongoing litigation regarding the ERS bonds will guide the parties with respect to claims, if any, that may impact the revision of the Commonwealth’s proposed Plan of Adjustment. While the Oversight Board has resumed Plan discussions, because of the fluid situation on the Island, the Oversight Board is unprepared at this time to propose a schedule for the Debtors’ Plan of Adjustment and Disclosure Statement processes."
No assurances can be given that debt restructuring negotiations will be successfully concluded, that 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 a materially adverse impact on Ambac's financial condition or results of operations.
Federal Aid
The Commonwealth of Puerto Rico is projected to benefit from over $49 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 $16.5 billion of the total 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 include 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. 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 $14 billion in federal aid under the CARES Act.
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 likely to be enacted. 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 six months ended June 30, 2020, Ambac had incurred losses associated with its Domestic Public Finance insured portfolio of $220 million, which was impacted by lower discount rates, the continued uncertainty and volatility of the situation in Puerto Rico, including the potential impact of the COVID-19 crisis on the Commonwealth and the developing potential impact of the COVID-19 crisis on other sectors in the Domestic Public Finance insured portfolio; and loss adjustment expenses related to the cost of defending our rights and pursuing recoveries. 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
| Ambac Financial Group, Inc. 55 2020 Second Quarter FORM 10-Q |

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.
Exposure Currency
The table below shows the distribution by currency of Ambac Assurance’s insured exposure as of June 30, 2020:

The increase in below investment grade exposures is primarily due the addition of certain exposures driven by the COVID-19 pandemic (lease and tax-backed, stadiums and an international structured finance exposure) partially offset by the commutation of certain general obligation exposures and the impact of foreign exchange rates resulting from the strengthening of the US Dollar.
Below investment grade exposures could continue to 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 June 30, 2020, was $35 million compared to a net loss attributable to common stockholders of $128 million for the three months ended June 30, 2019. The decreased loss was primarily driven by (i) lower insurance intangible amortization, (ii) net gain on derivative contracts in the current quarter, (iii) lower provision for income taxes, and (iv) lower operating and interest expenses, partially offset by: (a) increased losses and loss expenses, primarily due to the loss benefit in the three months ended June 30, 2019, driven by the Ballantyne commutation , (b) lower net investment income, and (c) lower net realized investment gains.
Net loss attributable to common stockholders for the six months ended June 30, 2020, was $315 million compared to a net loss attributable to common stockholders of $172 million for the six months ended June 30, 2019. The increase in loss was primarily driven by: (i) lower net investment income, (ii) lower net realized investment gains, (iii) 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 (a) lower insurance intangible amortization, (b) lower interest and operating expenses.

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 drove a net increase to loss reserves and losses on interest rate derivative contracts. Credit driven losses were also recognized in the three months ended March 31, 2020, within losses incurred (primarily from public finance insurance policies) and losses in counterparty credit adjustments on derivative asset valuations. Financial market disruptions were reflected through lower valuations of certain fixed income securities (recorded through other comprehensive income) and the majority of other investments (recorded through net investment income). During the second quarter of 2020, credit spreads partially recovered (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 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
| Ambac Financial Group, Inc. 57 2020 Second Quarter FORM 10-Q |

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, intangible assets, loss reserves and debt of the Company, had a significant impact on the comparability of the results of operation for the three and six months ended June 30, 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 and six months ended June 30, 2020 and 2019, 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 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 increased $3 million and decreased $14 million for the three and six months ended June 30, 2020, respectively, compared to the same periods 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:

|  | Three Months Ended June 30, |  | Six Months Ended June 30,
($ in millions) |  | 2020 |  | 2019 |  | 2020 |  | 2019
Normal premiums earned |  |  |  |  |  |  |  |
Public finance |  | $ | 5 |  |  | $ | 7 |  |  | $ | 10 |  |  | $ | 15 |
Structured finance |  | 2 |  |  | 3 |  |  | 4 |  |  | 6 |
International finance |  | 3 |  |  | 4 |  |  | 6 |  |  | 10 |
Total normal premiums earned |  | 10 |  |  | 14 |  |  | 20 |  |  | 30 |
Accelerated earnings |  | 1 |  |  | (6 | ) |  | 1 |  |  | 6 |
Total net premiums earned |  | $ | 11 |  |  | $ | 8 |  |  | $ | 21 |  |  | $ | 36 |

The decrease in normal premiums earned in the three and six months ended June 30, 2020, is primarily attributable to (i) the continued runoff of the insured portfolio in all markets and (ii) changes to allowance for credit losses on premiums receivables. Ambac adopted ASU 2016-13, Measurement of Credit Losses on Financial Instruments ("CECL"), on January 1, 2020, and will assess 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 and six months ended June 30, 2020, includes an increase in the allowance for credit losses since adoption of CECL of $2 million and $4 million, respectively, as compared to an increase of $1 million for the three and six months ended June 30, 2019. Terminations and accelerations, including those which occurred in prior periods, result in lower normal premiums earned in current and future periods. Public Finance normal earned premiums for the three and six months ended June 30, 2020, were also impacted by reinsurance cessions in the second half of 2019.
The increase in accelerated earnings in the three months ended June 30, 2020, as compared to the three months ended June 30, 2019, is primarily driven by negative accelerations related to the Ballantyne commutation that occurred in June 2019. The decrease in accelerated earnings in the six months ended June 30, 2020, as compared to the six months ended June 30, 2019, is primarily related to the COFINA restructuring that occurred in February 2019, partially offset by negative accelerations related to the Ballantyne commutation that occurred in June 2019.
Net Investment Income. Net investment income primarily consists of interest and net discount accretion on fixed income 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 income 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
| Ambac Financial Group, Inc. 58 2020 Second Quarter FORM 10-Q |

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 consist primarily of pooled fund investments in diversified asset classes. For further information about investment funds held, refer to Note 8. Investments to the Unaudited Consolidated Financial Statements, included in Part I, Item 1 in this Form 10-Q.
Net investment income from Ambac-insured securities; available-for-sale and short-term securities, other than Ambac-insured; and Other investments is summarized in the table below:

| Three Months Ended June 30, |  | Six Months Ended June 30,
($ in millions) | 2020 |  | 2019 |  | 2020 |  | 2019
Securities available-for-sale: Ambac-insured (including Secured Notes) | $ | 16 |  |  | $ | 58 |  |  | $ | 32 |  |  | $ | 87 |
Securities available-for-sale and short-term other than Ambac-insured | 10 |  |  | 20 |  |  | 25 |  |  | 38 |
Other investments (includes trading securities) | 27 |  |  | 8 |  |  | (25 | ) |  | 16 |
Net investment income | $ | 52 |  |  | $ | 87 |  |  | $ | 32 |  |  | $ | 141 |

Net investment income decreased $34 million and $110 million for the three and six months ended June 30, 2020, respectively, compared to the same periods in the prior year. As described further below, the variances were primarily driven by pricing volatility within fund investments resulting from the impact of the COVID-19 pandemic on financial markets, a smaller allocation to higher yielding Ambac-insured securities and a lower overall invested asset base.
Other investments income (loss) increased $19 million and decreased $41 million for the three and six months ended June 30, 2020, respectively, compared to the same periods in the prior year. Other investment income (loss) for the three months ended June 30, 2020, reflects the partial recovery of fair value losses reported in the first quarter of 2020, which were primarily in hedge and other fund investments focusing on asset-backed securities, equities, high-yield, leveraged loans and private credit. The first quarter 2020 losses were driven by adverse changes in fair values stemming from an increase in risk premiums (including credit spreads) as a consequence of the economic and financial market impact of the COVID-19 pandemic. The extent of market recovery on Ambac's investments in these funds varied during the second quarter of 2020, but in aggregate returned over half of first quarter losses. Ambac currently views year-to-date unrealized losses on its fund investments as temporary, subject to any subsequent decisions to monetize certain investments in connection with changes in liquidity needs, investment strategy, market conditions, and/or other circumstances. Other investment income for the three and six months ended June 30, 2019, was driven primarily by gains
on equity and high-yield and loan funds, partially offset by losses on insurance-linked securities.
Investment income from Ambac-insured securities was lower in both the three and six month periods ended June 30, 2020, compared to the prior year periods due primarily to the effects of 2019 de-risking activities and ongoing redemptions of Secured Notes issued by Ambac LSNI, LLC. Ambac's holdings of insured COFINA and Ballantyne bonds were settled in connection with the February 2019 COFINA commutation and June 2019 Ballantyne commutation, respectively. In addition to the reduced amount of holdings subsequent to these settlements, the Ballantyne transaction resulted in accelerated accretion on the bonds in the three months ended June 30, 2019, accounting for the majority of the decrease in income from Ambac-insured securities for both comparative periods. Additionally, income from Secured Notes is down as a result of early redemptions as well as lower LIBOR indexed coupon rates effective for the three and six months ended June 30, 2020, as compared to the three and six months ended June 30, 2019.
Net investment income from available-for-sales securities other than Ambac-insured securities decreased as a result of the favorable impact on income for the three and six months ended June 30, 2019, of high yielding uninsured COFINA bonds received under the POA, as well as the impact of a smaller asset base and lower average yields in 2020. All of the uninsured COFINA bonds were sold from Ambac's non-VIE investment portfolio by December 31, 2019. Portfolio repositioning away from BBB rated corporates, commercial mortgage backed securities and certain CLOs in the second quarter of 2020 also contributed to lower net investment income from available-for-sale securities for the three months ended June 30, 2020.
Net Realized Investment Gains (Losses). The following table provides a breakdown of net realized gains (losses) for the periods presented:

|  | Three Months Ended June 30, |  | Six Months Ended June 30,
($ in millions) |  | 2020 |  | 2019 |  | 2020 |  | 2019
Net gains (losses) on securities sold or called |  | $ | 9 |  |  | $ | 10 |  |  | $ | 16 |  |  | $ | 30 |
Net foreign exchange gains (losses) |  | 1 |  |  | 26 |  |  | 3 |  |  | 23 |
Credit impairments |  | — |  |  | — |  |  | — |  |  | — |
Intent / requirement to sell impairments |  | — |  |  | — |  |  | — |  |  | — |
Total net realized gains (losses) |  | $ | 10 |  |  | $ | 36 |  |  | $ | 18 |  |  | $ | 53 |

Net realized gains on securities sold or called for the three and six months ended June 30, 2020, are primarily from sales in connection with routine portfolio management. Net realized gains on securities sold or called for the three and six months ended June 30, 2019, included $7 million and $26 million, respectively, of net gains related to the impact of the COFINA Plan of Adjustment, including sales of Ambac-insured Puerto Rico COFINA bonds and new uninsured COFINA bonds received in the commutation. Also included in realized gains for the three and six months ended June
| Ambac Financial Group, Inc. 59 2020 Second Quarter FORM 10-Q |

30, 2019, are $23 million of realized foreign exchange gains arising from the settlement of Ballantyne bonds held in the investment portfolio.
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.
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 half of 2020, the economic hedge position has been adjusted. 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 and six months ended June 30, 2020, were $1 million and $(67) million, respectively, compared to ($36) million and $(52) million for the three and six months ended June 30, 2019, respectively. The net gain for the three months ended June 30, 2020, reflects a gain from reduced counterparty credit adjustments, partially offset by the impact of interest rate movements on the portfolio. The net loss for six months ended June 30, 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 and six months ended June 30, 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 $8 million and $(21) million for the three and six months ended June 30, 2020, respectively, and $(3) million for the three and six months ended June 30, 2019. The gain for the three months ended June 30, 2020, was driven by narrower credit spreads, in a partial reversal of first quarter 2020 results. The loss for the six months ended June 30, 2020, was driven by wider credit spreads, including the effect of a credit rating downgrade of a derivative counterparty by Ambac during the first quarter, simultaneous with an increase in the underlying asset value as interest rates declined.
Income (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. 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 a loss of less than a million and income of $3 million for the three and six months ended June 30, 2020, respectively, compared to income of $3 million and $19 million for the three and six months ended June 30, 2019, respectively. Results for the three months ended June 30, 2020, reflect the further reduction in value of net assets of a VIE driven by the ongoing shut-down of parts of the economy resulting from COVID-19. Results for the six months ended June 30, 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 a VIE driven by the economic uncertainty caused by COVID-19. Results for the six months ended June 30, 2019, were driven by the $15 million gain on consolidation of the COFINA Trust.
Refer to Note 3. Variable Interest Entities to the Unaudited Consolidated Financial Statements, included in Part I, Item 1 in this Form 10-Q for further information on the accounting for VIEs.
Losses and Loss Expenses. Losses and loss expenses are based upon estimates of the aggregate losses inherent in the non-derivative financial guarantee portfolio for insurance policies issued to beneficiaries, including unconsolidated VIEs.
Ambac records as a component of its loss reserve estimate subrogation recoveries related to securitized loans in RMBS transactions with respect to which Ambac Assurance 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
| Ambac Financial Group, Inc. 60 2020 Second Quarter FORM 10-Q |

warranty subrogation recoveries, net of reinsurance, of $1,731 million and $1,702 million at June 30, 2020, and December 31, 2019, 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, for more information regarding the estimation process for R&W subrogation recoveries.
The following provides details, by bond type, for losses and loss expenses (benefit) incurred for the periods presented:

|  | Three Months Ended June 30, |  | Six Months Ended June 30,
($ in millions) |  | 2020 |  | 2019 |  | 2020 |  | 2019
RMBS |  | $ | (35 | ) |  | $ | (69 | ) |  | $ | (118 | ) |  | $ | (108 | )
Domestic Public Finance |  | 42 |  |  | 50 |  |  | 220 |  |  | 120 |
Student Loans |  | 4 |  |  | (4 | ) |  | 18 |  |  | (7 | )
Ambac UK and Other Credits |  | 5 |  |  | (111 | ) |  | 12 |  |  | (125 | )
Totals (1) |  | $ | 16 |  |  | $ | (134 | ) |  | $ | 132 |  |  | $ | (121 | )

(1) | Includes loss expenses incurred (benefit) of $34 and $37 for the three and six months ended June 30, 2020, respectively, and ($1) and $28 for the three and six months ended June 30, 2019, respectively.

Losses and loss expenses (benefit) for the three and six months ended June 30, 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

• | Favorable RMBS development as a result of the positive impact of lower interest rates on excess spread, reduced by the negative impact of lower discount rates and expected losses from COVID-19 related delinquencies/defaults.

Losses and loss expenses (benefit) for the three and six months ended June 30, 2019, were driven by the following:

• | Favorable development within Ambac UK and Other Credits primarily due to the Ballantyne commutation;

• | Favorable RMBS development as a result of credit improvement, a trustee settlement related to Lehman sponsored transactions of $19 million and the impact on excess spread from declines in interest rates; partially offset by,

• | Higher projected losses in domestic public finance driven mostly by lower discount rates and additions to Puerto Rico loss reserves.

Insurance Intangible Amortization. Insurance intangible amortization for the three and six months ended June 30, 2020, was $14 million and $27 million, respectively, a decrease of $213 million and $236 million over the three and six months ended June 30, 2019, respectively. The decrease is primarily due to accelerated amortization as a result of the Ballantyne commutation that occurred in the second quarter of 2019.
Operating Expenses. Operating expenses consist of gross operating expenses plus reinsurance commissions. The following table provides a summary of operating expenses for the periods presented:

|  | Three Months Ended June 30, |  | Six Months Ended June 30,
($ in millions) |  | 2020 |  | 2019 |  | 2020 |  | 2019
Compensation |  | $ | 11 |  |  | $ | 17 |  |  | $ | 25 |  |  | $ | 32 |
Non-compensation |  | 10 |  |  | 12 |  |  | 19 |  |  | 22 |
Gross operating expenses |  | 20 |  |  | 29 |  |  | 44 |  |  | 54 |
Reinsurance commissions, net |  | — |  |  | — |  |  | — |  |  | — |
Total operating expenses |  | $ | 21 |  |  | $ | 29 |  |  | $ | 44 |  |  | $ | 54 |

Gross operating expenses decreased $9 million and $10 million for the three and six months ended June 30, 2020, respectively, compared to the same periods in the prior year. Operating expenses incurred relating to COVID-19 have been minimal for the three and six months ended June 30, 2020.
The decrease in operating expenses during the three months ended June 30, 2020 as compared to the three months ended June 30, 2019 was due to the following:

• | Lower compensation costs primarily related to lower salaries resulting from continued right sizing of staffing levels and incentive compensation costs related to changes in performance metrics primarily impacted by the Ballantyne restructuring and

• | Lower non-compensation costs primarily due to reduced legal and consulting services.

The decrease in operating expenses during the six months ended June 30, 2020 as compared to the six months ended June 30, 2019, was due to the following:

• | Lower compensation costs primarily due to lower salaries resulting from continued right sizing of staffing levels and incentive compensation costs related to changes in performance metrics primarily impacted by the Ballantyne restructuring and

• | Lower non-compensation costs primarily due to a UK Value Added Tax (VAT) refund recognized in the six months ended June 30, 2020, and reduced consulting services.

Legal and consulting services provided for the benefit of OCI amounted to $1 million and $1 million during the six months ended June 30, 2020 and 2019, respectively.
Interest Expense. Interest expense includes accrued interest on the Ambac Note, Tier 2 Notes, surplus notes and other debt obligations. Additionally, interest expense includes discount accretion when the debt instrument carrying value is at a discount to par.

The following table provides details by type of obligation for the periods presented:

|  | Three Months Ended June 30, |  | Six Months Ended June 30,

Total interest expense |  | $ | 58 |  |  | $ | 67 |  |  | $ | 122 |  |  | $ | 135 |

(1) | Includes junior surplus notes

The decrease in interest expense for the three and six months ended June 30, 2020, compared to the three and six months ended June 30, 2019, was primarily driven by optional redemptions and lower rate resets of the floating rate Ambac Note, and lower discount accretion on surplus notes, partially offset by interest compounding on the surplus notes and the Tier 2 Notes.
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 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. In accordance with their terms, Ambac Assurance has not requested to pay interest on any junior surplus notes since their issuance.
In April 2020, OCI declined the request of Ambac Assurance to pay the principal amount of the surplus notes, plus all accrued and unpaid interest thereon, on the scheduled maturity date of June 7, 2020. 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 Assurance 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 $323 million and $159 million, respectively, at June 30, 2020.
Provision for Income Taxes. The provision for income taxes for the three and six months ended June 30, 2020, was $2 million and a benefit of $4 million, a decrease of $26 million and $35 million compared to the provision for income taxes reported for three and six months ended June 30, 2019. The change for the three and six months ended June 30, 2020, as compared to the three and six months ended June 30, 2019, was primarily attributable to Ambac UK, which had higher taxable income in 2019 due to the Ballantyne restructuring and commutation, and a taxable loss, related to
investment losses on pooled funds, in the three months ended March 31, 2020.
LIQUIDITY AND CAPITAL RESOURCES
Ambac Financial Group, Inc. ("AFG") Liquidity. AFG's liquidity is primarily dependent on its cash, investments, and net receivables totaling $481 million as of June 30, 2020, and secondarily on its expense sharing and other arrangements with Ambac Assurance.

• | 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 Assurance 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 this $4 million reimbursement f or 2019 expenses, which was paid in March 2020.

AFG's investments include securities directly and indirectly issued by and/or insured by Ambac Assurance, some of which are eliminated in consolidation. Securities issued or insured by Ambac Assurance are generally less liquid than investment grade and other traded investments.
It is highly unlikely that Ambac Assurance will be able to make dividend payments to AFG for the foreseeable future and therefore cash and investments, payments under the intercompany cost allocation agreement and future tolling payments, if any, will be AFG’s principal source of liquidity in the 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, 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, for more information on dividend payment restrictions.
The principal uses of liquidity are the payment of operating expenses, including costs to explore opportunities to grow and diversify Ambac; and the making of investments, including securities issued or insured by Ambac Assurance. Future uses of liquidity may include the acquisition or capitalization of new businesses. Contingencies could cause material liquidity strains.
Ambac Assurance Liquidity. Ambac Assurance’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’s liquidity are gross installment premiums on insurance policies; principal and interest payments from investments; sales of investments; proceeds from repayment of
| Ambac Financial Group, Inc. 62 2020 Second Quarter FORM 10-Q |

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’s liquidity.
The principal uses of Ambac Assurance’s liquidity are the payment of operating and loss adjustment expenses, claims, commutation and related expense payments on insurance policies, ceded reinsurance premiums, principal and interest payments on the Ambac Note, surplus note principal and interest payments, Tier 2 Note payments, additional loans to affiliates, tolling payments due to AFG under the Amended TSA, and purchases of securities and other investments that may not be immediately converted into cash.

• | The COVID-19 pandemic has had a negative impact on Ambac's available liquidity as a consequence of the adverse reaction of the capital markets, which led to a reduction in the value and marketability of our invested assets; derivative losses, which required either timely settlement or additional collateral posting; and higher credit risk within the insured portfolio, as further described below. Nevertheless, Ambac has not yet experienced incremental demands on its liquidity, from higher claims or expenses, other than the aforementioned impact of derivatives.

• | Claim payments may increase during the global recession and COVID-19 pandemic as issuers, particularly those with revenues that will be interrupted by the effects of the pandemic, including social distancing, other restrictions on activities and the increase in unemployment, may not have sufficient cash inflows to pay debt service on Ambac-insured debt. 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.

Ambac Assurance's intercompany loans are with Ambac Financial Services ("AFS"). AFS uses interest rate derivatives (primarily interest rate swaps and US Treasury futures) as an economic hedge against the effects of rising interest rates elsewhere in the Company, including on Ambac Assurance’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 Assurance 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 Assurance 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 Assurance 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 Assurance 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 Assurance has not paid dividends on the AMPS since 2010. Ambac Assurance 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, 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, 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; 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, 2019, for more information about risks relating to our RMBS R&W subrogation recoveries.

Operating activities
The following represents the significant cash activities during the six months ended June 30, 2020 and 2019:

• | Cash used in operating activities relating to debt service on the Ambac Note was $58 million and $74 million for the six months ended June 30, 2020 and 2019, respectively.

• | Cash used in operating activities related to interest rate derivatives was $19 million and $51 million for the six months ended June 30, 2020 and 2019, respectively.

• | Cash used by operating activities relating to operating expenses was $44 million and $46 million for the six months ended June 30, 2020 and 2019, respectively.

• | Cash provided by operating activities relating to the investment portfolio was $58 million and $73 million for the six months ended June 30, 2020 and 2019, respectively.

• | Net loss and loss expenses paid, includin g commutation payments, during the six months ended June 30, 2020 and 2019 are detailed below:

| Six Months Ended June 30,
($ in million) | 2020 |  | 2019
Net loss and loss expenses paid (recovered): |  |  |
Net losses paid (1) | $ | 64 |  |  | $ | 298 |

Net loss expenses paid | 53 |  |  | 10 |
Net cash flow | $ | 61 |  |  | $ | 194 |

(1) | Net losses paid include commutation payments of $2 and $213 for the six months ended June 30, 2020 and 2019, respectively.

(2) | For or the six months ended June 30, 2019, subrogation received includes $36 of settlement proceeds related to Lehman sponsored RMBS transactions and $23 related to the COFINA Plan of Adjustment.

Future operating cash flows will primarily be impacted by the level of premium collections, investment coupon receipts and claim and expense payments.
Financing Activities
Financing activities for the six months ended June 30, 2020, include paydowns of the Ambac Note of $103 million and paydowns / maturities of VIE debt obligations of $99 million.
Financing activities for the six months ended June 30, 2019, include paydowns of the Ambac Note of $22 million and paydowns of VIE debt obligations of $92 million, proceeds of $19 million from the re-issuance of 1,386 shares of Ambac owned AMPS and proceeds of $12 million from issuance of Ambac UK debt.
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 (cash and securities collateral of $10 million and $155 million, respectively), including independent amounts, under these contracts at June 30, 2020.
Ambac Credit Products (“ACP”) is not required to post collateral under any of its outstanding credit derivative contracts.
BALANCE SHEET
Total assets decreased by approximately $558 million from December 31, 2019, to $12,761 million at June 30, 2020, primarily due to the negative total return for the non-VIE investment portfolio, payment of loss and loss adjustment expenses, and interest and operating expenses, lower valuation of certain VIE assets caused by the economic effects of the COVID-19 pandemic, as well as the decrease to consolidated VIE assets as a result of currency changes (strengthening of the US Dollar). Other significant changes during the six months ended June 30, 2020, were higher subrogation recoverables primarily related to increases in excess spread on RMBS as a result of lower interest rates and lower premium receivables and intangible assets from the continued runoff of the financial guarantee insurance portfolio.
Total liabilities decreased by approximately $151 million from December 31, 2019, to $11,632 million as of June 30, 2020, primarily due to lower consolidated VIE liabilities as a result of price and currency changes, as noted above, and lower long-term debt due to partial redemption of the Ambac Note, partially offset by higher loss reserves and increases in interest rate derivative obligations as a result of reductions in forward interest rates.
As of June 30, 2020, total stockholders’ equity was $1,129 million, compared with total stockholders’ equity of $1,536 million at December 31, 2019. This decrease was primarily due to a Total Comprehensive Loss during 2020. The Comprehensive Loss was primarily driven by the net loss attributable to common stockholders for the six months ended June 30, 2020, of $315 million, unrealized losses on available-for-sale investment securities of $42 million and translation losses on the consolidation of AFG's foreign subsidiaries of $48 million.

Investment Portfolio. Ambac Assurance’s investment objective is to achieve the highest risk-adjusted after-tax return on a diversified portfolio of primarily fixed income investments and pooled investment funds while employing asset/liability management practices to satisfy operating and strategic liquidity needs. Ambac Assurance’s investment portfolio is subject to internal investment guidelines and is subject to limits on types and quality of investments imposed by the insurance laws and regulations of the jurisdictions in which it is licensed, primarily the States of Wisconsin and New York. Such guidelines set forth minimum credit rating requirements and credit risk concentration limits. Within these guidelines, which in certain instances may be exceeded with the approval of the applicable regulatory authority, Ambac Assurance opportunistically purchases or sells Ambac Assurance insured securities given their relative risk/reward characteristics. Ambac Assurance’s investment policies are subject to oversight by OCI pursuant to the Settlement Agreement, the Stipulation and Order and the indenture for the Tier 2 Notes. The Board of Directors of Ambac Assurance approves any changes to Ambac Assurance's investment policy.
Ambac UK’s investment policy is designed with the primary objective of ensuring that Ambac UK is able to meet its financial obligations as they fall due, in particular with respect to policyholder claims. Ambac UK’s investment portfolio is primarily fixed income investments and diversified holdings of pooled investment funds. The portfolio is subject to internal investment guidelines and may be subject to limits on types and quality of investments imposed by the PRA as regulator of Ambac UK. Ambac UK’s investment policy sets forth minimum credit rating requirements and concentration limits, among other restrictions. The Board of Directors of Ambac UK approves any changes or exceptions to Ambac UK’s investment policy.
AFG's investment portfolio's primary objective is to preserve capital and liquidity for strategic uses while maximizing income.
Refer to Note 8. Investments to the Unaudited Consolidated Financial Statements included in Part I, Item 1 in this Form 10-Q for information about Ambac's consolidated investment portfolio. Ambac's investment policies and objectives do not apply to the assets of VIEs consolidated as a result of financial guarantees written by its insurance subsidiaries.
In the second quarter of 2020, Ambac monetized a material portion of its investments in certain assets classes; including corporate securities rated below the 'A' rated category, all directly owned CMBS (other than Military Housing bonds), and approximately 50% of all CLOs (all rated investment grade) and acquired additional distressed Ambac-insured securities. These actions resulted in changes to the credit rating distribution of available-for-sale investments from December 31, 2019, to June 30, 2020, illustrated in the charts below.
The following table summarizes the composition of Ambac’s investment portfolio, excluding VIE investments, at carrying value at June 30, 2020 and December 31, 2019:

($ in millions) |  | June 30, 2020 |  | December 31, 2019
Fixed income securities |  | $ | 2,218 |  |  | $ | 2,577 |
Short-term |  | 692 |  |  | 653 |
Other investments |  | 401 |  |  | 478 |
Fixed income securities pledged as collateral |  | 155 |  |  | 85 |
Total investments (1) |  | $ | 3,466 |  |  | $ | 3,792 |

(1) | Includes investments denominated in non-US dollar currencies with a fair value of £278 ($344) and €28.3 ($31.8) as of June 30, 2020, and £257 ($341) and €2 ($2) as of December 31, 2019.

Ambac invests in various asset classes in its fixed income securities portfolio, including securities covered by guarantees issued by Ambac Assurance and Ambac UK and other financial guarantors ("insured securities"). Other investments include diversified interests in pooled funds. Refer to Note 8. Investments to the Unaudited Consolidated Financial Statements included in Part I, Item 1 in this Form 10-Q for information about insured securities and fixed income and pooled funds by asset class.
The following table represents the fair value of other asset-backed securities, included in fixed income securities above, at June 30, 2020 and December 31, 2019, by classification:

($ in millions) |  | June 30, 2020 |  | December 31, 2019
Other asset-backed securities |  |  |  |
Military Housing |  | $ | 228 |  |  | $ | 237 |

Total other asset-backed securities |  | $ | 288 |  |  | $ | 287 |

| Ambac Financial Group, Inc. 65 2020 Second Quarter FORM 10-Q |

The following charts provide the ratings (1) distribution of the fixed income investment portfolio based on fair value at June 30, 2020 and December 31, 2019:

(1) | Ratings are based on the lower of Moody’s or S&P ratings. If ratings are unavailable from Moody's or S&P, Fitch ratings are used. If guaranteed, rating represents the higher of the underlying or guarantor’s financial strength rating.

(2) | Below investment grade and not rated bonds insured by Ambac represent 38% and 33% of the June 30, 2020 and December 31, 2019 combined fixed income portfolio, respectively.

Premium Receivables. Ambac's premium receivables decreased to $392 million at June 30, 2020, from $416 million at December 31, 2019. As further discussed in Note 6. Financial Guarantee Insurance Contracts, the decrease is due to premium receipts, changes to the allowance for credit losses, and changes in foreign currencies, partially offset by changes in expected and contractual cash flows and accretion of premium receivable discount.
Premium receivables by payment currency were as follows:

Currency (Amounts in millions) |  | Premium Receivable in Payment Currency |  | Premium Receivable in U.S. Dollars
U.S. Dollars |  | $ | 243 |  |  | $ | 243 |
British Pounds |  | £ | 103 |  |  | 127 |
Euros |  | € | 19 |  |  | 22 |
Total |  |  |  | $ | 392 |

Reinsurance Recoverable on Paid and Unpaid Losses. Ambac Assurance has reinsurance in place pursuant to surplus share treaty and facultative agreements. To minimize its exposure to losses from reinsurers, Ambac Assurance (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 Assurance in the event of rating agency downgrades of a reinsurer (among other events and circumstances). Ambac Assurance benefited from letters of credit and collateral amounting to approximately $129 million from its reinsurers at June 30, 2020. As of June 30, 2020 and December 31, 2019, reinsurance recoverable on paid and unpaid losses were $36 million and $26 million, respectively. The increase was primarily a result of adverse development in public finance and student loan insured exposures.
Insurance Intangible Asset. At the Fresh Start Reporting Date, an insurance intangible asset was recorded which represented the difference between the fair value and aggregate carrying value of the financial guarantee insurance and reinsurance assets and liabilities. As of June 30, 2020 and December 31, 2019, the net insurance intangible asset was $392 million and $427 million, 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 increased from $75 million at December 31, 2019, to $97 million as of June 30, 2020. Derivative liabilities increased from $90 million at December 31, 2019, to $134 million as of June 30, 2020. The net increases resulted primarily from lower interest rates during the six months ended June 30, 2020, with the effect on assets partially offset by higher 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. Refer to the "Critical Accounting Policies and Estimates" and “Results of Operations” sections of Management’s Discussion and Analysis of Financial Condition and Results of Operations, in addition to Basis of Presentation and Significant Accounting Policies and Loss Reserves sections included in Note 2.

The loss and loss expense reserves, net of subrogation recoverables and before reinsurance as of June 30, 2020 and December 31, 2019, were $(401) million and $(482) million, respectively.
Loss and loss expense reserves are included in the Unaudited Consolidated Balance Sheets as follows:

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%. The table below indicates gross par outstanding and the components of gross loss and loss expense reserves related to policies in Ambac’s gross loss and loss expense reserves at June 30, 2020 and December 31, 2019:

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 June 30, 2020, 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 Finance Variability," "Student Loan Variability," and "Other Credits, including Ambac UK, Variability," in Part II, Item 7 of the Company's 2019 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 Assurance to honor its financial obligations; the initiation of rehabilitation proceedings against Ambac Assurance; decreased likelihood of Ambac Assurance 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.
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.
Changes to assumptions that could make our reserves under-estimated include an increase in interest rates, deterioration in housing prices, poor servicing, 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; 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 $1,731 million, net of reinsurance, as of June 30, 2020, 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 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 June 30, 2020, could be approximately $35 million. Combined with the absence of any R&W subrogation recoveries, a possible increase in loss reserves for RMBS could be approximately $1,766 million. 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. 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 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 June 30, 2020, as compared to December 31, 2019, was primarily related to declines in discount rates; changes in assumptions on certain credits, particularly Puerto Rico; and the adverse impact on loss reserves from the global and issuer-specific economic impact of the COVID-19 pandemic. Total public finance gross loss reserves and related gross par outstanding on Ambac insured obligations by bond type were as follows:

Total |  | $ | 3,714 |  |  | $ | 799 |  |  | $ | 2,398 |  |  | $ | 627 |

(1) | Gross Par Outstanding includes capital appreciation bonds, which are reported at the par amount at the time of issuance of the insurance policy as opposed to the current accreted value of the bond.

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, such as hotel occupancy taxes, sales taxes, parking revenues, tolls, licensing fees, etc. A prolonged recovery from the COVID-19 related economic downturn 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 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 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 Assurance 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 changes in tax law that could reduce certain municipal investors' appetite for tax-exempt municipal bonds or put 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 of 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 revenues 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.
Our exposures to the Commonwealth of Puerto Rico are under stress arising from the Commonwealth’s poor financial condition, weak economy, loss of capital markets access and the severe damage caused by hurricanes Irma and Maria and other natural disasters. These factors, taken together with the payment moratorium on debt service of the Commonwealth and its instrumentalities, ongoing PROMESA Title III proceedings, and certain other provisions under PROMESA, the potential for restructurings of debt insured by Ambac Assurance, either with or without its consent, and the possibility of protracted litigation as a result of which its 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, 2019, for further details on the legal, economic and fiscal developments that have impacted or may impact Ambac Assurance’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. 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 June 30, 2020, the possible increase in loss reserves could be approximately $1,200 million. However, there can be no assurance that losses may not exceed 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. 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 June 30, 2020, the possible increase in loss reserves could be approximately $30 million. Additionally, an increase in interest rates of 0.50% could increase our estimate of expected losses by approximately $20 million. 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 $370 million greater than the loss reserves at June 30, 2020. Additionally, our loss reserves may be under-estimated as a result of the ultimate scope, duration 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, 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 June 30, 2020 and December 31, 2019 is below:

($ in millions) |  | June 30, 2020 |  | December 31, 2019
Surplus notes (1) |  | $ | 785 |  |  | $ | 769 |
Ambac note |  | 1,659 |  |  | 1,763 |
Tier 2 notes |  | 292 |  |  | 278 |
Ambac UK debt |  | 13 |  |  | 13 |
Total Long-term Debt |  | $ | 2,749 |  |  | $ | 2,822 |

(1) | Includes junior surplus notes.

The decrease in long-term debt from December 31, 2019, is primarily due to optional redemptions of $103 million of the Ambac Note, partially offset by the accretion on the carrying value of surplus notes, Tier 2 Notes and Ambac UK debt.
VARIABLE INTEREST ENTITIES
Please refer to Note 3. Variable Interest Entities to the Unaudited Consolidated Financial Statements included in Part I, Item 1 in this Form 10-Q and Note 2. Basis of Presentation and Significant Accounting Policies and Note 3. Variable Interest Entities 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, for information regarding variable interest entities.
ACCOUNTING STANDARDS
The following accounting standards have been issued but have not yet been adopted. We do not expect these standards to have a consequential impact on Ambac's financial statements.
Defined Benefit and Other Postretirement Plans Disclosures
In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20) - Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. The ASU modifies various disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Relevant disclosures that will be removed are: i) amounts in accumulated other comprehensive income expected to be recognized as net
| Ambac Financial Group, Inc. 70 2020 Second Quarter FORM 10-Q |

periodic benefit cost over the next fiscal year and ii) the effects of a one percentage point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of the net periodic pension cost and (b) benefit obligation for postretirement healthcare benefits. Relevant disclosures that will be added are an explanation of the reasons for significant gains and losses related to changes in the benefit obligations for the period. The ASU is effective for fiscal years ending after December 15, 2020, with early adoption permitted. The modified disclosures must be applied on a retrospective basis for all periods presented. Ambac will adopt this ASU on December 31, 2020.
Simplifying Income Tax Accounting
In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. The FASB issued this ASU as part of its initiative to reduce complexity in accounting standards. The ASU removes certain exceptions in the guidance related to investments, intraperiod allocations and interim period allocations. It further adds new guidance related to the allocation of consolidated income taxes and evaluating a step-up in the tax basis of goodwill. The ASU is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The modified disclosures must be applied on a retrospective basis for all periods presented. Ambac will adopt this ASU on January 1, 2021.
Please 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, for a discussion of the impact of other recent accounting pronouncements on Ambac’s financial condition and results of operations.
AMBAC ASSURANCE STATUTORY BASIS FINANCIAL RESULTS
Ambac Assurance statutory financial statements are prepared on the basis of accounting practices prescribed or permitted by the OCI. OCI recognizes only statutory accounting practices prescribed or permitted by the State of Wisconsin (“SAP”) for determining and reporting the financial condition and results of operations of an insurance company for determining its solvency under Wisconsin Insurance Law. The National Association of Insurance Commissioners (“NAIC”) Accounting Practices and Procedures manual (“NAIC SAP”) has been adopted as a component of prescribed practices by the State of Wisconsin. For further information, see "Ambac Assurance Statutory Basis Financial Results," in Part II, Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations," 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.
Ambac Assurance’s statutory policyholder surplus and qualified statutory capital (defined as the sum of policyholders surplus and mandatory contingency reserves) were $987 million and $1,527 million at June 30, 2020, respectively, as compared to $1,088 million and $1,618 million at December 31, 2019, respectively. As of June 30, 2020, statutory policyholder surplus and qualified statutory capital included $574 million principal balance of surplus notes outstanding, $365 million principal balance of junior surplus
notes outstanding and $138 million liquidation preference of preferred stock outstanding. These surplus and junior surplus notes (including related accrued interest of $507 million that is not recorded under statutory basis accounting principles), preferred stock and all other liabilities (including insurance claims and debt issued by Ambac Assurance) are obligations that have claims on the resources of Ambac Assurance that are senior to AFG's equity and therefore impact AFG's ability to realize residual value or receive dividends from Ambac Assurance.
The significant drivers to the net decrease in policyholder surplus are primarily due to a (i) statutory net loss of $58 million for the six months ended June 30, 2020 (excluding dividends from subsidiaries); (ii) a decrease of $28 million in the fair value of pooled fund investments and investment securities that are recorded at the lower of amortized cost or fair value; and (iii) contributions to contingency reserves of $9 million.
Ambac Assurance statutory surplus is sensitive to multiple factors, including: (i) loss reserve development, (ii) approval by OCI of payments on surplus notes and junior surplus notes, (iii) ongoing interest costs associated with the Ambac Note and Tier 2 Notes, including changes to interest rates as the Ambac Note is a floating rate obligation, (iv) deterioration in the financial position of Ambac Assurance subsidiaries that have their obligations guaranteed by Ambac Assurance, (v) first time payment defaults of insured obligations, which increase statutory loss reserves, (vi) commutations of insurance policies or credit derivative contracts at amounts that differ from the amount of liabilities recorded, (vii) reinsurance contract terminations at amounts that differ from net assets recorded, (viii) changes to the fair value of pooled fund and other investments carried at fair value, (ix) settlements of representation and warranty breach claims at amounts that differ from amounts recorded, including failures to collect such amounts or receive recoveries sufficient to pay or redeem the Ambac Note and Tier 2 Notes, (x) realized gains and losses, including losses arising from other than temporary impairments of investment securities, and (xi) future changes to prescribed practices by the OCI.
AMBAC UK FINANCIAL RESULTS UNDER UK ACCOUNTING PRINCIPLES
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 £398 million at June 30, 2020, as compared to £387 million at December 31, 2019. At June 30, 2020, the carrying value of cash and investments was £471 million, an increase from £470 million at December 31, 2019. The increase in shareholders’ funds and cash & investments was primarily due to the continued receipt of premiums and foreign exchange gains, partially offset by losses within Ambac UK's investment portfolio and tax and other operating expense 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 £180 million at June 30, 2020, of which £166 million were eligible to meet solvency capital requirements. This is a reduction from
| Ambac Financial Group, Inc. 71 2020 Second Quarter FORM 10-Q |

December 31, 2019, when available capital resources were a surplus of £188 million of which £178 million were eligible to meet solvency capital requirements. The eligible capital resources at June 30, 2020, and December 31, 2019, were in comparison to regulatory capital requirements of £242 million and £208 million respectively. Ambac UK is therefore deficient in terms of compliance with applicable regulatory capital requirements by £76 million and £30 million at June 30, 2020, and December 31, 2019, respectively. The deficit increased as at June 30, 2020, due to an increase in regulatory capital requirements for non-life insurers in the credit and surety line of business and due to a reduction in eligible capital resources mainly caused by the fall over the period in long term discount rates. 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.
The following paragraphs define each non-GAAP financial measure and describe why it is useful. A reconciliation of the non-GAAP financial measure and the most directly comparable GAAP financial measure is also presented below.
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.

• | Insurance intangible amortization: Elimination of the amortization of the financial guarantee insurance intangible asset that arose as a result of Ambac’s emergence from bankruptcy and the implementation of Fresh Start reporting. This adjustment ensures that all financial guarantee contracts are accounted for consistent with the provisions of the Financial Services – Insurance Topic of the ASC.

• | Foreign exchange (gains) losses: Elimination of the foreign exchange gains (losses) on the re-measurement of assets, liabilities and transactions in non-functional currencies. This adjustment eliminates the foreign exchange gains (losses) on all assets, liabilities and transactions in non-functional currencies, which enables users of our financial statements to better view the results without the impact of fluctuations in foreign currency exchange rates and facilitates period-to-period comparisons of Ambac's operating performance.

Adjusted Book Value. Adjusted Book Value is defined as Total Ambac Financial Group, Inc. stockholders’ equity as reported under GAAP, adjusted for after-tax impact of the following:

• | 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. These adjustments allow for all financial guarantee contracts to be accounted for within Adjusted Book Value consistent with the provisions of the Financial Services—Insurance Topic of the ASC, whether or not they are subject to derivative accounting rules.

• | Insurance intangible asset: Elimination of the financial guarantee insurance intangible asset that arose as a result of Ambac’s emergence from bankruptcy and the implementation of Fresh Start reporting. This adjustment ensures that all financial guarantee contracts are accounted for within Adjusted Book Value consistent with the provisions of the Financial Services—Insurance Topic of the ASC.

• | Net unearned premiums and fees in excess of expected losses: 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. This non-GAAP adjustment adds UPR in excess of expected losses, net of reinsurance, to stockholders’ equity for financial guarantee contracts where expected losses are less than UPR.

• | Net unrealized investment (gains) losses in Accumulated Other Comprehensive Income: Elimination of the unrealized gains and losses on the Company’s investments that are recorded as a component of accumulated other comprehensive income (“AOCI”). The AOCI component of the fair value adjustment on the investment portfolio may differ from realized gains and losses ultimately recognized by the Company based on the Company’s investment strategy. This adjustment only allows for such gains and losses in Adjusted Book Value when realized.

The following table reconciles Total Ambac Financial Group, Inc. stockholders’ equity to the non-GAAP measure Adjusted Book Value on a dollar amount and per share basis, for all periods presented:

| June 30, 2020 |  | December 31, 2019
($ in millions, except share data) | $ Amount |  | Per Share |  | $ Amount |  | Per Share
Total Ambac Financial Group, Inc. stockholders’ equity | $ | 1,069 |  |  | $ | 23.34 |  |  | $ | 1,477 |  |  | $ | 32.41 |
Adjustments: |  |  |  |  |  |  |
Non-credit impairment fair value losses on credit derivatives | 1 |  |  | 0.03 |  |  | — |  |  | 0.01 |
Insurance intangible asset | (392 | ) |  | (8.57 | ) |  | (427 | ) |  | (9.37 | )
Net unearned premiums and fees in excess of expected losses | 396 |  |  | 8.63 |  |  | 414 |  |  | 9.09 |
Net unrealized investment (gains) losses in Accumulated Other Comprehensive Income | (109 | ) |  | (2.38 | ) |  | (151 | ) |  | (3.31 | )
Adjusted book value | $ | 965 |  |  | $ | 21.06 |  |  | $ | 1,313 |  |  | $ | 28.83 |

The decrease in Adjusted Book Value was primarily attributable to the Adjusted Loss for the six months ended June 30, 2020, excluding earned premium previously included in Adjusted Book Value, and the impact of changes in foreign exchange rates resulting from the strengthening of the U.S. Dollar.
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, (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 Disclosures about Market Risk

Market risk represents the potential for losses that may result from 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 six months ended June 30, 2020, related 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 ended December 31, 2019.
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 debt 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 income 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 June 30, 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 $0.2 million for a 1 basis point parallel shift in USD benchmark interest rates up or down. 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 June 30, 2020:

($ in millions) |  | Estimated Change in Net Fair Value |  | Estimated Net Fair Value
300 basis point rise |  | $ | 18 |  |  | $ | (503 | )
200 basis point rise |  | 17 |  |  | (504 | )
100 basis point rise |  | 15 |  |  | (506 | )
Base scenario |  | — |  |  | (521 | )
100 basis point decline(1) |  | 2 |  |  | (519 | )
200 basis point decline(1) |  | 5 |  |  | (516 | )

(1) | Incorporates an interest rate floor of 0%.

Due to the low interest rate environment as of June 30, 2020, stress scenarios involving interest rate declines greater than 200 basis points are not meaningful to Ambac's portfolios.
| Ambac Financial Group, Inc. 74 2020 Second Quarter FORM 10-Q |

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 June 30, 2020. It is more likely that actual changes in credit spreads will vary by obligor:

($ in millions) |  | Estimated Change in Net Fair Value |  | Estimated Net Fair Value
250 Basis Point Widening |  | $ | (24 | ) |  | $ | (61 | )
50 Basis Point Widening |  | (6 | ) |  | (43 | )
Base Scenario |  | — |  |  | (37 | )
50 basis Point Narrowing |  | 5 |  |  | (32 | )
250 basis Point Narrowing |  | 25 |  |  | (12 | )

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 June 30, 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 June 30, 2020. It is more likely that actual changes in credit spreads will vary by security:

($ in millions) |  | Estimated Change in Net Fair Value |  | Estimated Net Fair Value
250 Basis Point Widening |  | $ | (134 | ) |  | $ | 1,895 |
50 Basis Point Widening |  | (27 | ) |  | 2,002 |
Base Scenario |  | — |  |  | 2,029 |
50 Basis Point Narrowing |  | 25 |  |  | 2,054 |
250 Basis Point Narrowing |  | 75 |  |  | 2,104 |

Item 4. | Controls and Procedures.

In connection with the preparation of this second 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 June 30, 2020, 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 June 30, 2020 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, 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 than as described below.
Risks Related to Insured Portfolio Losses
Catastrophic public health events, like the COVID-19 pandemic, that result in material disruption of economic activity can have a materially negative impact on the 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 business and results of operations. Ambac insures the obligations of a number of issuers that have been, or may in the future be, substantially affected by the economic effects of COVID-19, such as municipalities and securitizations, including those backed by consumer loans such as mortgages or student loans. As described more fully in 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 as well as 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 government and other governments globally have taken certain measures 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 collection 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 other debt service payments than would have occurred without governmental intervention, Ambac may experience higher losses 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 determined by a number of factors including, but not limited 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 timelines 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 reserves due to the factors described above and the inherent uncertainties in estimating losses given the evolving nature of the pandemic and its 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 our results of operations and financial condition.

Item 5. | Other Information

Compensatory Arrangements of Certain Officers
On August 3, 2020, the Compensation Committee of the AFG Board approved certain amendments to the employment agreement of Claude LeBlanc to provide that Mr. LeBlanc would be eligible to receive an enhanced severance payment if his employment is terminated by the Company other than for “cause” (including notice of non-renewal by the Company) or Mr. LeBlanc terminates his employment for “good reason” in contemplation of and no more than 120 days prior to, or one year following the occurrence of, a “Change in Control” (as defined in his employment agreement). In that event, the multiplier used to determine the severance payment that Mr. LeBlanc would otherwise be entitled to receive shall be 2.5 x instead of 2.0 x the sum of (a) one year’s base salary and (b) the amount equal to the annual target incentive award for the calendar year in which the date of termination occurs. The foregoing description of the amendments to Mr. LeBlanc’s employment agreement is only a summary, does not purport to be complete, and is qualified in its entirety by reference to the full text of the Amended and Restated Employment Agreement dated as of August 3, 2020 by and among AFG, AAC and Claude LeBlanc, which is filed as Exhibit 10.2 to this Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2020, and is incorporated into this filing by reference.
