PART I

ITEM 1.BUSINESS

Overview

Assured Guaranty Ltd. (AGL and, together with its subsidiaries, Assured Guaranty or the Company) is a Bermuda-based holding company incorporated in 2003 that provides, through its operating subsidiaries, credit protection products to the United States (U.S.) and international public finance (including infrastructure) and structured finance markets. The Company applies its credit underwriting judgment, risk management skills and capital markets experience primarily to offer financial guaranty insurance that protects holders of debt instruments and other monetary obligations from defaults in scheduled payments. If an obligor defaults on a scheduled payment due on an obligation, including a scheduled principal or interest payment (Debt Service)(debt service), the Company is required under its unconditional and irrevocable financial guaranty to pay the amount of the shortfall to the holder of the obligation. The Company markets its financial guaranty insurance directly to issuers and underwriters of public finance and structured finance securities as well as to investors in such obligations. The Company guarantees obligations issued principally in the U.S. and the United Kingdom (U.K.), and also guarantees obligations issued in other countries and regions, including Australia and Western Europe. The Company also provides other forms of insurance that are in line with its risk profile and benefit from its underwriting experience.

The Company conducts its financial guaranty business on a direct basis from the following companies: Assured Guaranty Municipal Corp. (AGM), Municipal Assurance Corp. (MAC), Assured Guaranty Corp. (AGC), and Assured Guaranty (Europe) Ltd.plc (AGE). It also conducts business through Bermuda-based reinsurers Assured Guaranty Re Ltd. (AG Re) and Assured Guaranty Re Overseas Ltd. (AGRO), Bermuda-based reinsurers.. The following is a description of AGL's principal operating subsidiaries:

Assured Guaranty Municipal Corp. AGM is located and domiciled in New York, was organized in 1984 and commenced operations in 1985.York. Since mid-2008, AGM has provided financial guaranty insurance and reinsurance only on debt obligations issued in the U.S. public finance and global infrastructure markets, including bonds issued by U.S. state or governmental authorities or notes issued to finance infrastructure projects. Previously, AGM was organized in 1984 as "Financial Security Assurance Inc." and until 2008 also offered insurance and reinsurance in the global structured finance market, including asset-backed securities issued by special purpose entities. AGM formerly was named Financial Security Assurance Inc. Assured Guaranty acquired AGM, together with its holding company Financial Security Assurance Holdings Ltd. (renamed Assured Guaranty Municipal Holdings Inc., AGMH)market. AGM's subsidiary AGE offers insurance and reinsurance in the subsidiaries owned by that holding company, on July 1, 2009.global public finance and structured finance markets.

Municipal Assurance Corp. MAC is located and domiciled in New York and was organized in 2008. Assured Guaranty acquired MAC on May 31, 2012. On July 16, 2013, Assured Guaranty completed a series of transactions that increased the capitalization of MAC and resulted in MAC assuming a portfolio of geographically diversified U.S. public finance exposure from AGM and AGC. MAC offers insurance and reinsurance on bonds issued by U.S. state or municipal governmental authorities, focusing on investment grade obligations in select sectors of the municipal market.

Assured Guaranty Corp. AGC is located in New York and domiciled in Maryland, was organized in 1985 and commenced operations in 1988. It provides insurance and reinsurance on debt obligations in the global structured finance market and also offers guarantees on obligations in the U.S. public finance and international infrastructure markets.

On July 1, 2016, AGC acquired all of the issued and outstanding capital stock of CIFG Holding Inc. (together with its subsidiaries, CIFGH) (the CIFG Acquisition). AGC merged CIFG Assurance North America, Inc. (CIFGNA), a financial guaranty insurer subsidiary of CIFGH, in 2016 and Radian Asset Assurance Inc. (Radian Asset) in 2015, and merged them each with and into AGC, with AGC asbeing the surviving company, on July 5, 2016. The CIFG Acquisition added $4.2 billion of net par insured on July 1, 2016.entity.

On April 1, 2015 (Radian Acquisition Date), AGC completed the acquisition of all of the issued and outstanding capital stock of financial guaranty insurer Radian Asset Assurance Inc. (Radian Asset) (Radian Asset Acquisition). Radian Asset was merged with and into AGC, with AGC as the surviving company of the merger. The Radian Asset Acquisition added $13.6 billion to the Company's net par outstanding on April 1, 2015.

On January 10, 2017, AGC completed its acquisition of MBIA UK Insurance Limited (MBIA UK) (MBIA UK Acquisition), the European operating subsidiary of MBIA Insurance Corporation (MBIA). As of December 31, 2016, MBIA UK had an insured portfolio of approximately $12 billion of net par. MBIA UK has changed its name to Assured Guaranty (London) Ltd. (AGLN). Assured Guaranty currently maintains AGLN as a stand-alone

entity. Assured Guaranty is actively working to combine AGLN with its other affiliated European insurance companies. Any such combination will be subject to regulatory and court approvals; as a result, Assured Guaranty cannot predict when, or if, such a combination will be completed.

Assured Guaranty (Europe) Ltd.plc AGE is a U.K. incorporated company licensed as a U.K. insurance company and is currently authorized to operate in various countries throughout the European Economic Area (EEA). It was organized in 1990 and issued its first financial guarantee in 1994. AGE offers financial guarantees in both the international public finance and structured finance markets and currently is the primaryonly entity from which the Company writes business in the EEA. As discussed further under "Business" below, AGE has agreed with its regulator that new business it writes would be guaranteed using a co-insurance structure pursuant to which AGE would co-insure municipal and infrastructure transactions with AGM, and structured finance transactions with AGC. AGE must obtain the approval of the Prudential Regulation Authority (PRA) before it can guarantee any new structured finance transaction.

The Company combined the operations of its European subsidiaries, AGE, Assured Guaranty (UK) plc (AGUK), Assured Guaranty (London) plc (AGLN) and CIFG Europe S.A. (CIFGE), in a transaction that was completed on November 7, 2018. Under the combination, AGUK, AGLN and CIFGE transferred their insurance portfolios to and merged with and into AGE (the Combination). See Part II, Item 8, Financial Statements and Supplementary Data, Note 1, Business and Basis of Presentation, for additional information on the Combination.


AGC had acquired MBIA UK Insurance Limited (MBIA UK) (MBIA UK Acquisition), the European operating subsidiary of MBIA Insurance Corporation (MBIA), on January 10, 2017. As of December 31, 2016, MBIA UK had an insured portfolio of approximately $12 billion of net par. MBIA UK immediately changed its name and subsequently converted to a public limited company, Assured Guaranty (London) plc.
Assured Guaranty Re Ltd. and Assured Guaranty Re Overseas Ltd. AG Re is incorporated under the laws of Bermuda and is licensed as a Class 3B insurer under the Insurance Act 1978 and related regulations of Bermuda. AG Re indirectly owns indirectly, AGRO, which is a Bermuda Class 3A and Class C insurer. AG Re and AGRO underwrite financial guaranty reinsurance, and AGRO also underwrites other non-financial guaranty insurance and reinsurance that is in line with the Company's risk profile and benefits from its underwriting experience. AG Re and AGRO write business as reinsurers of third-party primary insurers and of certain affiliated companies.

Assured Guaranty is the market leader in the financial guaranty industry. The Company's position in the market has benefitedbenefits from its acquisition of AGMH in 2009 as well as subsequent acquisitions of financial guarantors, its ability to maintain strong financial strength ratings, its strong claims-paying resources, its proven willingness and ability to make claim payments to policyholders after obligors have defaulted, and its ability to achieve recoveries in respect of the claims that it has paid on insured residential mortgage-backed and other securities and to resolve its troubled municipal credits to which it had exposure.exposures.

The Company faces competition in the U.S. public finance financial guaranty market.market from Build America Mutual Assurance Company (BAM). The Company estimates, based on third party industry compilations, that the Company insured approximately 56% of the par of the insured U.S. public finance bonds issued in the primary market in 2016, the Company2018, while BAM insured approximately 56%44% of the par, while Build America Mutual Assurance Company (BAM), insured 40% of the par. National Public Finance Guarantee Corporation (National), an affiliate of MBIA, insured the remaining 4% of the balance. The continued presence in the market of BAM affects the Company's insured volume as well as the amount of premium the Company is able to charge.

The sustained low interest rate environment in the U.S. has also presentspresented the Company with challenges. Over the last several years, interest rates generally have been lower than historical norms. Average municipal interest rates were extremely low duringWhile higher than in 2016, withwhen the benchmark AAA 30-year Municipal Market Data (MMD) index published by Thomson Reuters (MMD Index),was at times below 2%, a threshold not previously crossedthe average for that rate was 3.05% in the modern era.2018, still low by historical standards. As a result, the difference in yield (or the credit spread) between a bond insured by Assured Guaranty and an uninsured bond has provided comparatively little room for issuer savings and insurance premium, and Assured Guaranty has seen a lower demand for its financial guaranty insurance from issuers over the past several years than it saw historically.

In addition, the Company's business continues to be affected by negative perceptions of the value of the financial guaranty insurance sold by other companies that had been active in the industry. The losses suffered by such other insurers resulted in those companies being downgraded to below-investment-grade (BIG) levels by the rating agencies and/or subject to intervention by their state insurance regulators. In a number of cases, the state insurance regulators prevented the distressed financial guaranty insurers from paying claims or paying such claims in full; also, such financial guaranty insurers were perceived by market participants not to be actively conducting surveillance on transactions or fully exercising rights and remedies to mitigate losses.

The Company believes that issuers and investors in securities will continue to purchase financial guaranty insurance, especially if interest rates rise and credit spreads widen. U.S. municipalities have budgetary requirements that are best met through financings in the fixed income capital markets. In particular,Historically, smaller municipal issuers have frequently useused financial guaranties in order to access the capital markets with new debt offerings at a lower all-in interest rate than on an unguaranteed basis. In addition, the Company expects long-term debt financings for infrastructure projects will grow throughout the world, as will the financing needs associated with privatization initiatives or refinancing of infrastructure projects in developed countries.

The Company evaluates the amount of capital it requires based on an internal capital model as well as rating agency models and insurance regulations. The Company believes it has excess capital based on these measures, and has been returning some of its excess capital to shareholders by repurchasing its common shares and has been deploying some of its excess capital to acquire financial guaranty portfolios and alternative investments.    

The Company considers opportunities to acquire financial guaranty portfolios, whether by acquiring financial guarantors who are no longer actively writing new business or their insured portfolios (including through reinsurance), or by commuting business that it had previously ceded. In the last several years, the Company has reassumed a number of previously ceded portfolios and has completed the acquisition of Radian Asset, CIFG Holding Inc. (CIFGH, and together with its subsidiaries, CIFG) (the CIFG Acquisition) and the MBIA UK Acquisition. On June 1, 2018, the Company closed a transaction with Syncora Guarantee Inc. (SGI) (SGI Transaction) under which AGC assumed, generally on a 100% quota share basis, substantially all of SGI’s insured portfolio and AGM reassumed a book of business previously ceded to SGI by AGM. The Company continues to investigate additional opportunities related to remaining legacy financial guaranty portfolios, but there can be no assurance if or when the Company will find suitable opportunities on appropriate terms.

During 2016, the Company also established an alternative investments group to focus on deploying a portion of the Company's excess capital to pursue acquisitions and develop new business opportunities that complement the Company's financial guaranty business, are in line with its risk profile and benefit from its core competencies. The alternative investments group has been investigating a number of such opportunities, including, among others, both controlling and non-controlling investments in investment managers. In February 2017, the Company agreed to purchase up to $100 million of limited partnership interests in a fund that invests in the equity of private equity managers. TheIn September 2017, the Company also considers opportunities to acquire financial guaranty portfolios, whether by acquiring financial guarantors who are no longer actively writing new business or their insured portfolios, or by commuting businessacquired a minority interest in Wasmer, Schroeder & Company LLC, an

independent investment advisory firm specializing in separately managed accounts (SMAs). In February 2018, the Company acquired a minority interest in the holding company of Rubicon Infrastructure Advisors, a full-service investment firm based in Dublin that it had previously ceded.provides investment banking services within the global infrastructure sector. The Company continues to investigate additional opportunities.opportunities to make alternative investments, including, among others, both controlling and non-controlling investments in investment managers, but there can be no assurance if or when the Company will find suitable opportunities on appropriate terms.
 
Insurance Portfolio - Financial Guaranty Portfolio

Financial guaranty insurance generally provides an unconditional and irrevocable guaranty that protects the holder of a debt instrument or other monetary obligation against non-payment of scheduled principal and interest payments when due. Upon an obligor's default on scheduled principal or interestdebt service payments due on the debt obligation, whether due to its insolvency or otherwise, the Company is generally required under the financial guaranty contract to pay the investor the principal or interest shortfall then due.

Financial guaranty insurance may be issued to all of the investors of the guaranteed series or tranche of a municipal bond or structured finance security at the time of issuance of those obligations or it may be issued in the secondary market to only specific individual holders of such obligations who purchase the Company's credit protection.

Both issuers of and investors in financial instruments may benefit from financial guaranty insurance. Issuers benefit when they purchase financial guaranty insurance for their new issue debt transaction because the insurance may have the effect of lowering an issuer's interest cost over the life of the debt transaction to the extent that the insurance premium charged by the Company is less than the net present value of the difference between the yield on the obligation insured by Assured Guaranty (which carries the credit rating of the specific subsidiary that guarantees the debt obligation) and the yield on the debt obligation if sold on the basis of its uninsured credit rating. The principal benefit to investors is that the Company's guaranty provides increased certainty that scheduled payments will be received when due. The guaranty may also improve the marketability and liquidity of obligations issued by infrequent or unknown issuers, as well as obligations with complex structures or backed by asset classes new to the market. This benefit to market liquidity, which we call a liquidity benefit, results from the increase in secondary market trading values for Assured Guaranty-insured obligations as compared with uninsured obligations by the same issuer. In general the liquidity benefit of financial guaranties is thatand especially in such instances, investors aremay be able to sell bonds insured bondsby highly rated financial guarantors more quickly than uninsured debt obligations and, depending on the difference between the financial strength rating of the insurer and the rating of the issuer, at a higher secondary market price than for uninsured debt obligations.

As an alternative to traditional financial guaranty insurance, in the past the Company also provided credit protection relating to a particular security or obligor through a credit derivative contract, such as a credit default swap (CDS). Under the terms of a CDS, the seller of credit protection agreedagrees to make a specified payment to the buyer of credit protection if one or more specified credit events occurs with respect to a reference obligation or entity. In general, the Company, as the seller of credit protection, specified as credit events specified in the Company'sits CDS are forfailure to pay interest and principal defaults on the reference obligation. One difference between CDS and traditional primary financial guaranty insurance is that credit default protection was typically provided to a particular buyer of credit protection, who is not always required to own the reference obligation, rather than to all investors in the reference obligation. As a result, the Company's rights and remedies under a CDS may be different and more limited than on a financial guaranty of an entire issuance. Credit derivatives were preferred by some investors, however, because they generally offered the investor ease of execution and standardized terms as well as more favorable accounting or capital treatment. Due to changes in the regulatory environment, the Company has not provided credit protection in the U.S. through a CDS since March 2009, other than in connection with loss mitigation and other remediation efforts relating to its existing book of business. See the Risk Factor captioned "Changes in or inability to comply with applicable law could adversely affect the Company's ability to do business" under Risks Related to GAAPaccounting principles generally accepted in the United States of America (GAAP) and Applicable Law in "Item 1A. Risk Factors" for additional detail about the regulatory environment. The Company has acquired or reinsured portfolios both before and after 2009 that include financial guaranty contracts in credit derivative form.

The Company also offers credit protection through reinsurance, and in the past has provided reinsurance to other financial guaranty insurers with respect to their guaranty of public finance, infrastructure and structured finance obligations. The Company believes that the opportunities currently available to it in the reinsurance market primarily consist primarily of potentially assuming portfolios of transactions from inactive primary insurers, such as the SGI Transaction, and recapturing portfolios that it has previously ceded to third party reinsurers.

The Company's financial guaranty direct and assumed businesses provide credit protection on public finance, infrastructure and structured finance obligations. When the Company directly insures an obligation, it assigns the obligation to a geographic location or locations based on its view of the geographic location of the risk. For information on the geographic

breakdown of the Company's financial guaranty portfolio and on its income and revenue by jurisdiction, see Part II, Item 8, Financial Statements and Supplementary

Data, Note 4, Outstanding Exposure, Geographic Distribution of Net Par Outstanding, and Note 12, Income Taxes, Provision for Income Taxes.

U.S. Public Finance Obligations   The Company insures and reinsures a number of different types of U.S. public finance obligations, including the following:

General Obligation Bonds are full faith and credit bonds that are issued by states, their political subdivisions and other municipal issuers, and are supported by the general obligation of the issuer to pay from available funds and by a pledge of the issuer to levy ad valorem taxes in an amount sufficient to provide for the full payment of the bonds.
     
Tax-Backed Bonds are obligations that are supported by the issuer from specific and discrete sources of taxation. They include tax-backed revenue bonds, general fund obligations and lease revenue bonds. Tax-backed obligations may be secured by a lien on specific pledged tax revenues, such as a gasoline or excise tax, or incrementally from growth in property tax revenue associated with growth in property values. These obligations also include obligations secured by special assessments levied against property owners and often benefit from issuer covenants to enforce collections of such assessments and to foreclose on delinquent properties. Lease revenue bonds typically are general fund obligations of a municipality or other governmental authority that are subject to annual appropriation or abatement; projects financed and subject to such lease payments ordinarily include real estate or equipment serving an essential public purpose. Bonds in this category also include moral obligations of municipalities or governmental authorities.
  
Municipal Utility Bonds are obligations of all forms of municipal utilities, including electric, water and sewer utilities and resource recovery revenue bonds. These utilities may be organized in various forms, including municipal enterprise systems, authorities or joint action agencies.

Transportation Bonds include a wide variety of revenue-supported bonds, such as bonds for airports, ports, tunnels, municipal parking facilities, toll roads and toll bridges.

Healthcare Bonds are obligations of healthcare facilities, including community based hospitals and systems, as well as of health maintenance organizations and long-term care facilities.

Higher Education Bonds are obligations secured by revenue collected by either public or private secondary schools, colleges and universities. Such revenue can encompass all of an institution's revenue, including tuition and fees, or in other cases, can be specifically restricted to certain auxiliary sources of revenue.

Infrastructure Bonds include obligations issued by a variety of entities engaged in the financing of infrastructure projects, such as roads, airports, ports, social infrastructure and other physical assets delivering essential services supported by long-term concession arrangements with a public sector entity.

Housing Revenue Bonds are obligations relating to both single and multi-family housing, issued by states and localities, supported by cash flow and, in some cases, insurance from entities such as the Federal Housing Administration.

Investor-Owned Utility Bonds are obligations primarily backed by investor-owned utilities, first mortgage bond obligations of for-profit electric or water utilities providing retail, industrial and commercial service, and also include sale-leaseback obligation bonds supported by such entities.

Other Public Finance Bonds include other debt issued, guaranteed or otherwise supported by U.S. national or local governmental authorities, as well as student loans, revenue bonds, and obligations of some not-for-profit organizations.

A portion of the Company's exposure to tax-backed bonds, municipal utility bonds and transportation bonds constitutes "special revenue" bonds under the U.S.United States Bankruptcy Code.Code (Bankruptcy Code). Even if an obligor under a special revenue bond were to seek protection from creditors under Chapter 9 of the U.S. Bankruptcy Code, holders of the special revenue bond should continue to receive timely payments of principal and interest during the bankruptcy proceeding, subject to the special revenues being sufficient to pay debt service and the lien on the special revenues being subordinate to the necessary operating expenses of the project or system from which the revenues are derived. While "special revenues" acquired by the

obligor after bankruptcy remain subject to the pre-petition pledge, special revenue bonds may be adjusted if their claim is determined to be "undersecured."

Non-U.S. Public Finance Obligations    The Company insures and reinsures a number of different types of non-U.S. public finance obligations, which consist of both infrastructure projects and other projects essential for municipal function such as regulated utilities. Credit support for the exposures written by the Company may come from a variety of sources, including some combination of subordinated tranches, over-collateralization or cash reserves. Additional support also may be provided by transaction provisions intended to benefit noteholders or credit enhancers. The types of non-U.S. public finance securities the Company insures and reinsures include the following:

Regulated Utility Obligations are issued by government-regulated providers of essential services and commodities, including electric, water and gas utilities. The majority of the Company's international regulated utility business is conducted in the U.K.

Infrastructure Finance Obligations are obligations issued by a variety of entities engaged in the financing of international infrastructure projects, such as roads, airports, ports, social infrastructure, and other physical assets delivering essential services supported either by long-term concession arrangements with a public sector entity or a regulatory regime. The majority of the Company's international infrastructure business is conducted in the U.K.

Regulated Utilities Obligations are issued by government-regulated providers of essential services and commodities, including electric, water and gas utilities. The majority of the Company's international regulated utility business is conducted in the U.K.

Pooled Infrastructure Obligations are synthetic asset-backed obligations that take the form of CDS obligations or credit-linked notes that reference either infrastructure finance obligations or a pool of such obligations, with a defined deductible to cover credit risks associated with the referenced obligations.

Other Public Finance Obligations include obligations of local, municipal, regional or national governmental authorities or agencies.

U.S. and Non-U.S. Structured Finance Obligations    The Company insures and reinsures a number of different types of U.S. and non-U.S. structured finance obligations. Credit support for the exposures written by the Company may come from a variety of sources, including some combination of subordinated tranches, excess spread, over-collateralization or cash reserves. Additional support also may be provided by transaction provisions intended to benefit noteholders or credit enhancers. The types of U.S. and Non-U.S. Structured Financenon-U.S. structured finance obligations the Company insures and reinsures include the following:

Pooled Corporate Obligations are securities primarily backed by various types of corporate debt obligations, such as secured or unsecured bonds, bank loans or loan participations and trust preferred securities (TruPS). These securities are often issued in "tranches," with subordinated tranches providing credit support to the more senior tranches. The Company's financial guaranty exposures generally are to the more senior tranches of these issues.

Residential Mortgage-Backed Securities (RMBS) are obligations backed by closed-end and open-end first and second lien mortgage loans on one-to-four family residential properties, including condominiums and cooperative apartments. The Company has not insured a RMBS transaction since January 2008, although it has acquired RMBS insurance exposures since that time in connection with its acquisition or reinsurance of legacy financial guaranty portfolios. First lien mortgage loan products in these transactions include fixed rate, adjustable rate and option adjustable-rate mortgages. The credit quality of borrowers covers a broad range, including "prime", "subprime" and "Alt-A". A prime borrower is generally defined as one with strong risk characteristics as measured by factors such as payment history, credit score, and debt-to-income ratio. A subprime borrower is a borrower with higher risk characteristics, usually as determined by credit score and/or credit history. An Alt-A borrower is generally defined as a prime quality borrower that lacks certain ancillary characteristics, such as fully documented income. The Company has not insured a RMBS transaction since January 2008.

Insurance Securitization Obligations are obligations secured by the future earnings from pools of various types of insurance/insurance and reinsurance policies and income produced by invested assets.

Consumer Receivables Securities are obligations backed by non-mortgage consumer receivables, such as student loans, automobile loans and leases, manufactured home loans and other consumer receivables.

Pooled Corporate Obligations are securities primarily backed by various types of corporate debt obligations, such as secured or unsecured bonds, bank loans or loan participations and trust preferred securities. These securities are often issued in "tranches," with subordinated tranches providing credit support to the more senior tranches. The Company's financial guaranty exposures generally are to the more senior tranches of these issues.


Financial Products Business"Business is how the Company refers to the guaranteed investment contracts (GICs) portion of a line of business previously conducted by AGMHAssured Guaranty Municipal Holdings Inc. (AGMH) that the Company did not acquire when it purchased AGMH in 2009 from Dexia SA and that is being run off. That line of business was comprisedconsisted of AGMH's guaranteed investment contracts business, its medium term notes business and the equity payment agreements associated with AGMH's leveraged lease business. Assured Guaranty is indemnified byAlthough Dexia SA and certain of its affiliates (Dexia) assumed the liabilities related to such businesses when the Company purchased AGMH, AGM policies related to such businesses remained outstanding. Assured Guaranty is indemnified by Dexia against loss from the former Financial Products Business.

Until November 2008, AGMH’s former financial products segment had been in the business of borrowing funds through the issuance of GICs insured by AGM and reinvesting the proceeds in investments that met AGMH’s investment criteria. In June 2009, in connection with the Company's acquisition of AGMH from Dexia Holdings Inc., Dexia SA, the ultimate parent of Dexia Holdings Inc., and certain of its affiliates, entered into a number of agreements intended to mitigate the credit, interest rate and liquidity risks associated with the GIC business and the related AGM insurance policies. Some of those agreements have since terminated or expired, or been modified. As of December 31, 2018, the aggregate accreted GIC balance was approximately $1.0 billion, compared with approximately $10.2 billion as of December 31, 2009. As of December 31, 2018, the aggregate fair market value of the assets supporting the GIC business plus cash and positive derivative value exceeded by nearly $0.8 billion the aggregate principal amount of all outstanding GICs and certain other business and hedging costs of the GIC business.

Commercial Receivables Securities are obligations backedAGMH's financial products business had also issued medium term notes insured by equipment loans or leases, aircraft and aircraft engine financings, business loans and trade receivables. Credit support is derived fromAGM, reinvesting the cash flows generated by the underlying obligations, as well as property or equipment values as applicable.proceeds in investments that met AGMH's investment criteria. As of December 31, 2018, only $171 million of insured medium term notes remain outstanding.

The Company also provides non-financial guaranty insurance and reinsurance in transactions with similar risk profiles to its structured finance exposures written in financial guaranty form. The Company provides such type of asset is a tax benefit to be realized by an investor in one of the Federal or state programs that permit such investor to receive a credit against taxes (such as Federal corporate income tax or statenon-financial guaranty insurance premium tax)and reinsurance, for making qualified investments in specified enterprises, typically located in designated low-income areas.example, for life insurance capital relief transactions and aircraft residual value insurance (RVI) transactions.    

Exposure Limits, Underwriting Procedures, and Credit Policy and Underwriting Procedure

Credit PolicyExposure Limits

The Company establishes exposure limits and underwriting criteria for obligors, sectors and countries, and in the case of structured finance and infrastructure exposures, for individual transactions. Risk exposure limits for single obligors are based on the Company's assessment of potential frequency and severity of loss as well as other factors, such as historical and stressed collateral performance. Sector limits are based on the Company’s view of stress losses for the sector and on its assessment of intra-sector correlation. Country limits are based on the size and stability of the relevant economy, and the Company’s view of the political environment and legal system. All of the foregoing limits are established in relation to the Company's capital base.

Underwriting Procedures
Each transaction underwritten by the Company involves persons with different skills and backgrounds across various departments within the Company. The Company's transaction underwriting teams include both underwriters and lawyers, who analyze the structure of a potential transaction and the credit and legal issues pertinent to the particular line of business or asset class, and accounting and finance personnel, who review the more complex transactions to determine the appropriate accounting treatment.
Upon completion of the underwriting analysis, the underwriter prepares a formal credit report that is submitted to a credit committee for review. An oral presentation is usually made to the committee, followed by questions from committee

members and discussion among the committee members and the underwriters. In some cases, additional information may be presented at the meeting or required to be submitted prior to approval. Each credit committee decision is documented and any further requirements, such as specific terms or evidence of due diligence, are noted. The Company's credit committees are composed of senior officers of the Company excluding those senior officers responsible for business origination. The committees are organized by asset class, such as for public finance or structured finance, or along regulatory lines, to assess the various potential exposures.
Upon approval by the credit committee, the underwriter, working with the responsible attorney, is responsible for closing the transaction and issuing the policy. At policy issuance, the underwriter and the responsible attorney certify that the transaction closed meets the terms and conditions agreed to by the credit committee.
Credit Policy

U.S. Public Finance

For U.S. public finance transactions, the Company's underwriters generally analyze the issuer's historical financial statements and, where warranted, develop stress case projections to test the issuer's ability to make timely debt service payments under stressful economic conditions.
The Company focuses principally on the credit quality of the obligor based on population size and trends, wealth factors, and strength of the economy. The Company evaluates the obligor’s liquidity position; its fiscal management policies and track record; its ability to raise revenues and control expenses; and its exposure to derivative contracts and to debt subject to acceleration. The Company assesses the obligor’s pension and other post-employment benefits obligations and funding policies and evaluates the obligor’s ability to adequately fund such obligations in the future. The Company analyzes other critical risk factors including the type of issue; the repayment source; pledged security, if any; the presence of restrictive covenants and the tenor of the risk. The Company also considers the ability of obligors to file for bankruptcy or receivership under applicable statutes (and on related statutes that provide for state oversight or fiscal control over financially troubled obligors). In addition,The Company also considers the environmental impact associated with the transaction. The Company weighs the risk of a rating agency downgrade of an obligation's underlying uninsured rating.

For certain transactions, underwriting considerations may also include: the importance of the proposed project to the community; the financial management of a specific project; the potential refinancing risk; and legal or administrative risks.
In cases of not-for-profit institutions, such as healthcare issuers and private higher education issuers, the Company emphasizesfocuses on the financial stability of the institution, its competitive position and its management experience.
    
ForThe Company’s credit policy for U.S. infrastructure transactions the Company's due diligence is generally the same as it is for internationalsubstantially similar to that of non-U.S. infrastructure transactions as described below.

U.S. structured finance obligations generally present three distinct forms of risk: asset risk, pertaining to the amount and quality of assets underlying an issue; structural risk, pertaining to the extent to which an issue's legal structure provides protection from loss; and execution risk, which is the risk that poor performance by a servicer or collateral manager contributes to a decline in the cash flow available to the transaction. Each of these risks is addressed through the Company's underwriting process.

Generally, the amount and quality of asset coverage required with respect to a structured finance exposure is dependent upon both the historic performance of the asset class, as well as the Company’s view of the future performance of the subject assets. Future performance expectations are developed from historical loss experience, taking into account economic, social and political factors affecting that asset class as well as, to the extent feasible, the subject assets themselves. Conclusions are then drawn about the amount of over-collateralization or other credit enhancement necessary in a particular transaction in order to protect investors (and therefore the insurer or reinsurer) against poor asset performance. In addition, structured securities usually are designed to protect investors (and therefore the insurer or reinsurer) from the bankruptcy or

insolvency of the entity that originated the underlying assets, as well as the bankruptcy or insolvency of the servicer or manager of those assets.

The Company conducts extensive due diligence on the collateral that supports its insured transactions. The principal focus of the due diligence is to confirm the underlying collateral was originated in accordance with the stated underwriting criteria of the asset originator. To this end, such collateral is reviewed, either internally by the Company or by outside consultants that the Company engages. The Company also conducts audits of servicing or other management procedures, reviewing critical aspects of these procedures such as cash management and collections. The Company may, for certain transactions, obtain background checks on key managers of the originator, servicer or manager of the obligations underlying that transaction.Non-U.S. Transactions
 
In general,For non-U.S. transactions are comprised of structured finance transactions, transactions with regulated utilities, or infrastructure transactions. For these transactions, the Company undertakes an analysis of the country or countries in which the risk resides, which includes political risk as well as economic and demographic characteristics. For each transaction, the Company also performs an assessment of the legal framework governing the transaction and the laws affecting the underlying assets supporting the obligations to be insured.

In general, non-U.S. transactions consist of transactions with regulated utilities or infrastructure transactions. The underwriting of structured finance and regulated utilities is generally the same as for U.S. transactions, but for considerations relatedwith additional consideration given to factors specific to the specific country as described in the previous paragraph. relevant jurisdiction.

For non-U.S. infrastructure transactions, the Company reviews the type of project (e.g., hospital, road, social housing, transportation or student accommodation) and the source of repayment of the debt. For certain transactions, debt service and operational expenses are covered by availability payments made by either a governmental entity or a not-for-profit entity. The availability payments are due if the project is available for use, regardless of whether the project actually is in use. The principal risks for such transactions are construction risk and operational risk. The project must be completed on time and must be available for use during the life of the concession. For other transactions, notably transactions secured by toll-roads and student accommodation, revenues derived from the project must be sufficient to make debt service payments as well as cover operating expenses during the concession period.

For infrastructure transactions, underwriters generally use financial models in order to evaluate the ability of the transaction to generate adequate cash flow to service the debt under a variety of scenarios. The models include economically stressed scenarios that the underwriters use for their assessment of the potential credit risk inherent in a particular transaction. Stress models developed internally by the Company's underwriters reflect both empirical research and information gathered

from third parties, such as rating agencies or investment banks. The Company undertakes due diligencemay also engage advisors such as consultants and external counsel to assess demand risksassist in such projects and often uses consultants to help assess future demand and revenue and expense projections.analyzing a transaction's financial or legal risks.

The Company’s due diligence for infrastructure projects also includes: a financial review of the entity seeking the development of the project (usually a governmental entity or university); a financial and operational review of the developer, the construction companies, and the project operator; and a financial review of the various providers of operational financial protection for the bondholders (and therefore the insurer), including construction surety providers, letter-of-credit providers, liquidity banks or account banks. The Company uses outside consultants to review the construction program and to assess whether the project can be completed on time and on budget. The Company projects the cost of replacing the construction company, including delays in construction, in the event that a construction company is unable to complete the construction for any reason. Construction security packages are sized appropriately to cover these risks and the Company requires such coverage from credit-worthy institutions.

Underwriting ProcedurePrior to the global financial crisis of 2008, the Company insured non-U.S. structured financial transactions, and it may do so again. If it does, it expects its underwriting process generally to be the same as for U.S. structured finance transactions described below, but with additional consideration given to factors specific to the relevant jurisdiction.

Each of these risks is addressed through the Company's financial guaranty direct business, underwriters generally analyze the issuer's historical financial statements and, where warranted, develop stress case projections to test the issuers' ability to make timely debt service payments under stressful economic conditions. In theunderwriting process.
For structured and infrastructure finance portions of the Company's financial guaranty direct business,transactions, underwriters generally use computer-based financial models in order to evaluate the ability of the transaction to generate adequate cash flow to service the debt under a variety of hypothetical scenarios. The models include economically stressed scenarios that the underwriters use for their assessment of the potential credit risk inherent in a particular transaction. Stress models developed internally by the Company's underwriters reflect both empirical research and information gathered from third parties, such as rating agencies or investment banks. Generally, the amount and quality of asset coverage required with respect to a structured finance exposure is dependent upon both the historic performance of the asset class, as well as the Company’s view of the future performance of the subject assets.
The Company may also engage advisors such as consultants and external counsel to assist in analyzing a transaction's financial or legal risks. The Company may also conduct a due diligence review that includes, among other things, a site visit to the project or facility, meetings with issuer management, review of underwriting and operational procedures, file reviews, and review of financial procedures and computer systems.

Risk Management Procedures

Organizational Structure

The Company's policies and procedures relating to risk assessment and risk management are overseen by its Board of Directors (the Board). The Board takes an enterprise-wide approach to risk management that is designed to support the Company's business plans at a reasonable level of risk. A fundamental part of risk assessment and risk management is not only understanding the risks a company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for the Company. The Board annually approves the Company's business plan, factoring risk management into account. It also approves the Company's risk appetite statement, which articulates the Company's tolerance for risk and describes the general types of risk that the Company accepts or attempts to avoid. The involvement of the Board in setting the Company's business strategy is a key part of its assessment of management's risk tolerance and also a determination of what constitutes an appropriate level of risk for the Company.

While the Board has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibility for risk assessment and risk management. The Risk Oversight Committee of the Board oversees the standards, controls, limits, underwriting guidelines and policies that the Company establishes and implements in respect of credit underwriting and risk management. It focuses on management's assessment and management of both (i) credit risks and (ii) other risks, including, but not limited to, financial, legal and operational risks (including cybersecurity risks), and risks relating to the Company's reputation and ethical standards. In addition, the Audit Committee of the Board is responsible for, among other matters, reviewing policies and processes related to the evaluation of risk assessment and risk management, including the Company's major financial risk exposures and the steps management has taken to monitor and control such exposures. It also reviews compliance with legal and regulatory requirements.requirements (including cybersecurity requirements). The Compensation Committee of the Board reviews compensation-related risks to the Company. The Finance Committee of the Board oversees the investment of the Company's investment portfolio and the Company's capital structure, liquidity, financing arrangements, rating agency matters, and any corporate development activities in support of the Company's financial plan. The Nominating and Governance Committee of the Board oversees risk at the Company by developing appropriate corporate governance guidelines and identifying qualified individuals to become board members.

The Company has established a number of management committees to develop underwriting and risk management guidelines, policies and procedures for the Company's insurance and reinsurance subsidiaries that are tailored to their respective businesses, providing multiple levels of credit review, analysis and analysis.control.

Portfolio Risk Management Committee—This committee establishes company-wide credit policy for the Company's direct and assumed business. It implements specific underwriting procedures and limits for the Company and allocates underwriting capacity among the Company's subsidiaries. The Portfolio Risk Management Committee is responsible for enterprise risk management for the Company on a consolidated basis and focuses on measuring and managing credit, market and liquidity risk for the overall company.Company. All transactions in new asset classes or new jurisdictions must be approved by this committee.

U.S. Management Committee—This committee establishes strategic policy and reviews the implementation of strategic initiatives and general business progress in the U.S. The U.S. Management Committee approves risk policy at the U.S. operating company level.

Risk Management Committees—The U.S., U.K., AG Re and AG ReAGRO risk management committees conduct an in-depth review of the insured portfolios of the relevant subsidiaries, focusing on varying portions of the portfolio at each meeting. They assignreview and may revise internal ratings ofassigned to the insured transactions and review sector reports, monthly product line surveillance reports and compliance reports.

Workout Committee—This committee receives reports from surveillance and workout personnel on transactions that might benefit from active loss mitigation or risk reduction, and approves loss mitigation or risk reduction strategies for such transactions.

Reserve Committees—Oversight of reserving risk is vested in the U.S. Reserve Committee, the U.K. Reserve Committee, the AG Re Reserve Committee and the U.K.AGRO Reserve Committee. The committees review the reserve methodology and assumptions for each major asset class or significant BIG transaction, as well as the loss projection scenarios used and the probability weights assigned to those scenarios. The reserve committees establish reserves for the relevant subsidiaries, taking into consideration supporting information provided by surveillance personnel.

The Company's surveillance personnel are responsible for monitoring and reporting on all transactions in the insured portfolio, including exposures in both the financial guaranty direct and assumed businesses. The primary objective of the surveillance process is to monitor trends and changes in transaction credit quality, detect any deterioration in credit quality, and recommend remedial actions to management. All transactions in the insured portfolio are assigned internal credit ratings, and surveillance personnel recommend adjustments to those ratings to reflect changes in transaction credit quality. The Company monitors its insured portfolio and refreshes its internal credit ratings on individual exposures in quarterly, semi-annual or annual cycles based on the Company’s view of the exposure’s quality, loss potential, volatility and sector. Ratings on exposures in sectors identified as under the most stress or with the most potential volatility are reviewed every quarter, although the Company may also review a rating in response to developments impacting the credit when a ratings review is not scheduled.

The Company's workout personnel are responsible for managing workout, loss mitigation and risk reduction situations. They work together with the Company's surveillance personnel to develop and implement strategies on transactions that are experiencing loss or could possibly experience loss. They develop strategies designed to enhance the ability of the

Company to enforce its contractual rights and remedies and mitigate potential losses. The Company's workout personnel also engage in negotiation discussions with transaction participants and, when necessary, manage (along with legal personnel) the Company's litigation proceedings. They may also make open market or negotiated purchases of securities that the Company has insured, or negotiate or otherwise implement consensual terminations of insurance coverage prior to contractual maturity. The Company's workoutsurveillance personnel work with servicers of RMBS transactions to enhance their performance.

Direct Business

The Company monitors the performance of each risk in its portfolio and tracks aggregation of risk. The review cycle and scope vary based upon transaction type and credit quality. In general, the review process includes the collection and analysis of information from various sources, including trustee and servicer reports, financial statements, general industry or sector news and analyses, and rating agency reports. For public finance risks, the surveillance process includes monitoring general economic trends, developments with respect to state and municipal finances, and the financial situation of the issuers. For structured finance transactions, the surveillance process can include monitoring transaction performance data and cash flows, compliance with transaction terms and conditions, and evaluation of servicer or collateral manager performance and financial condition. Additionally, the Company uses various quantitative tools and models to assess transaction performance and identify situations where there may have been a change in credit quality. For all transactions, surveillanceSurveillance activities may include discussions with or site visits to issuers, servicers or other parties to a transaction.

Assumed Business

For transactions that the Company has assumed, the ceding insurers are responsible for conducting ongoing surveillance of the exposures that have been ceded to the Company.Company, except that the Company provides surveillance for exposures assumed from SGI. The Company's surveillance personnel monitor the ceding insurer's surveillance activities on exposures ceded to the Company through a variety of means, including reviews of surveillance reports provided by the ceding insurers, and meetings and discussions with their analysts. The Company's surveillance personnel also monitor general news and information, industry trends and rating agency reports to help focus surveillance activities on sectors or creditsexposures of particular concern. For certain exposures, the Company also will undertake an independent analysis and remodeling of the exposure. In the event of credit deterioration of a particular exposure, more frequent reviews of the ceding company's risk mitigation activities are conducted. The Company's surveillance personnel also take steps to ensure that the ceding insurer is managing the risk pursuant to the terms of the applicable reinsurance agreement. To this end, the Company conducts periodic reviews of ceding companies' surveillance activities and capabilities. That process may include the review of the insurer's underwriting, surveillance and claim files for certain transactions.

Ceded Business

As part of its risk management strategy prior to the global financial crisis of 2008, the Company obtained third party reinsurance or retrocessions to reduce its exposure tofor various risk concentrations, such as for single risk limits, portfolio credit rating or exposure limits, geographic limits or other factors, to increase its underwriting capacity, both on an aggregate-riskmanagement purposes, and a single-risk basis, to meet internal, rating agency and regulatory risk limits, diversify risks, reduce the need for additional capital, and strengthen financial ratios. The Company receives capital credit for ceded reinsurancemay do so again in the capital models used by the rating agencies to evaluate the Company's capital position for its financial strength ratings and in its own internal capital models. The amount of the credit depends on the reinsurer's rating and any collateral it may post. During and after the financial crisis, most of the Company's reinsurers were downgraded by one or more rating agencies, and the effect of such downgrades, in general, was to

decrease the financial benefits of using reinsurance.future. Over the past several years the Company has entered into commutation agreements reassuming portions of the previously ceded business from certain reinsurers; as of December 31, 2016,2018, approximately 4%1%, or $11.2$2.6 billion, of its principal amount outstanding was still ceded to third party reinsurers, down from 12%, or $86.5 billion, as of December 31, 2009. In the future, the Company may enter into new commutation agreements to reassume portions of its insured business ceded to other reinsurers, but such opportunities are expected to be limited given the small number of unaffiliated reinsurers currently reinsuring the Company.

More recently theThe Company has obtained excess-of-loss reinsurance in part to augment its capital in the capital modelmodels used by S&P Global Ratings, a division of Standard & Poor's Financial Services LLC (S&P)certain rating agencies to evaluate itsthe Company's financial strength ratings.

Importance of Financial Strength Ratings

Low financial strength ratings or uncertainty over the Company's ability to maintain its financial strength ratings would have a negative impact on issuers' and investors' perceptions of the value of the Company's insurance product. Therefore, the Company manages its business with the goal of achieving high financial strength ratings, preferably the highest that an agency will assign to a financial guarantor. However, the models used by rating agencies differ, presenting conflicting goals that may make it inefficient or impractical to reach the highest rating level. In addition, the models are not fully transparent, contain subjective factors and may change.

Historically, insuranceInsurance financial strength ratings reflect a rating agency's opinion of an insurer's ability to pay under its insurance policies and contracts in accordance with their terms. The rating is not specific to any particular policy or contract. It does not refer to an insurer's ability to meet non-insurance obligations and is not a recommendation to purchase any policy or contract issued by an insurer or to buy, hold, or sell any security insured by an insurer. The insurance financial strength ratings assigned by the rating agencies are based upon factors that the rating agencies believe are relevant to policyholders and are not directed toward the protection of investors in AGL's common shares. Ratings reflect only the views of the respective rating agencies assigning them and are subject to continuous review and revision or withdrawal at any time.

Following the financial crisis, the rating process has been challenging for the Company due to a number of factors, including:

Instability of Rating Criteria and Methodologies. Rating agencies purport to issue ratings pursuant to published rating criteria and methodologies. In recent years,Beginning during the financial crisis, the rating agencies have made material changes to their rating criteria and methodologies applicable to financial guaranty insurers, sometimes through formal changes and other times through ad hoc adjustments to the conclusions reached by existing criteria. Furthermore, these criteria and methodology changes were typically implemented without any transition period, making it difficult for an insurer to comply quickly with new standards. In December 2018, S&P Global Ratings, a division of Standard & Poor's Financial Services LLC (S&P), proposed changes to its ratings methodology for bond insurers which it said are unlikely to affect any existing credit ratings on bond insurers.

Instability of Severe Stress Case Loss Assumptions. A major component in arriving at a financial guaranty insurer's rating has been the rating agency’s assessment of the insurer’s capital adequacy, with each rating agency employing its own proprietary model. These capital adequacy approaches include “stress case” loss assumptions for various risks or risk categories. Since the financial crisis, the rating agencies have at various times materially increased stress case loss assumptions for various risks or risk categories, in some cases later reducing such stress case losses. This approach has made predicting the amount of capital required to maintain or attain a certain rating more difficult.

More Reliance on Qualitative Rating Criteria. In prior years, the financial strength ratings of the Company’s insurance company subsidiaries were largely consistent with the rating agency’s assessment of the insurers’ capital adequacy, such that a rating downgrade could generally be avoided by raising additional capital or otherwise

improving capital adequacy under the rating agency’s model. In recent years, however, both S&P and Moody’s Investors Service, Inc. (Moody’s) have applied other factors, some of which are subjective, such as the insurer's business strategy and franchise value or the anticipated future demand for its product, to justify ratings for the Company’s insurance company subsidiaries significantly below the ratings implied by their own capital adequacy models. Currently, for example, S&P has concluded that AGMAssured Guaranty has “AAA” capital adequacy under the S&P model (but subject to a downward adjustment due to a “large“largest obligor test”) and Moody’s has concluded that AGM has “Aa” capital adequacy under the Moody’s model (offset by other factors including the rating agency’s assessment of competitive profile, future profitability and market share).

Despite the difficult rating agency process following the financial crisis, the Company has been able to maintain strong financial strength ratings. However, if a substantial downgrade of the financial strength ratings of the Company's insurance subsidiaries were to occur in the future, such downgrade would adversely affect its business and prospects and, consequently, its results of operations and financial condition. The Company believes that if the financial strength ratings of AGM, AGC and/or MACany of its insurance subsidiaries were downgraded from their current levels, such downgrade could result in downward pressure on the premium that such insurance subsidiary would be able to charge for its insurance. Currently, AGM, AGC and MAC all have AA (Stable Outlook) financial strength ratings from S&P. Each of AGM and MAC also has a AA+ (Stable Outlook) financial strength rating from Kroll Bond Rating Agency (KBRA), while AGC has a AA (Stable Outlook) financial strength rating from KBRA. AGM and AGC have financial strength ratings in the single-A category from Moody's (A2 (Stable Outlook) and A3 (Stable Outlook), respectively), although AGC announced on January 13, 2017 that it had requested that Moody's withdraw its financial strength rating of AGC. In addition, AGRO has been assigned a rating of A+ (Stable) from A.M. Best Company, Inc. (Best), which is Best's second highest rating. The Company periodically assesses the value of each rating assigned to each of its companies, and may as a result of such assessment request that a rating agency add or drop a rating from certain of its companies. For example, the KBRAKroll Bond Rating Agency (KBRA) ratings were first assigned to MAC in 2013, and to AGM in 2014, to AGC in 2016 and theto AGE in 2018; an A.M. Best Company, Inc. (Best) rating was first assigned to AGRO in 2015,2015; while a Moody's rating was never requested for MAC, was dropped from AG Re and AGRO in 2015, and as noted above, iswas the subject of a rating withdrawal request in the case of AGC.AGC (which request was declined).

The Company believes that so long as AGM, AGC and/or MAC continue to have financial strength ratings in the double-A category from at least one of the legacy rating agencies (S&P or Moody’s), they are likely to be able to continue writing financial guaranty business with a credit quality similar to that historically written. However, if neither legacy rating agency maintained financial strength ratings of AGM, AGC and/or MAC in the double-A category, or if either legacy rating agency were to downgrade AGM, AGC and/or MAC below the single-A level, it could be difficult for the Company to originate the current volume of new financial guaranty business with comparable credit characteristics.

Investments

Investment income from the Company's investment portfolio is one of the primary sources of cash flow supporting its operations and claim payments. The Company's total investment portfolio was $11.0$10.9 billion and $11.2$11.4 billion as of December 31, 20162018 and 2015,2017, respectively, and generated net investment income of $398 million, $418 million and $408 million $423 millionin 2018, 2017 and $403 million in 2016, 2015 and 2014, respectively.

The Company's principal objectives in managing its investment portfolio are to support the highest possible ratings for each operating company; maintain sufficient liquidity to cover unexpected stress in the insurance portfolio; and maximize total after-tax net investment income. If the Company's calculations with respect to its policy liabilities are incorrect or other unanticipated payment obligations arise, or if the Company improperly structures its investments to meet these liabilities, it could have unexpected losses, including losses resulting from forced liquidation of investments before their maturity. The investment policies of the Company's insurance subsidiaries are subject to insurance law requirements, and may change depending upon regulatory, economic and market conditions and the existing or anticipated financial condition and operating requirements, including the tax position, of the businesses.

Approximately 83%86% of the Company's investment portfolio is externally managed by itsseven investment managers: BlackRock Financial Management, Inc., Goldman Sachs Asset Management, L.P., General Re-NewNew England Asset Management, Inc. and, Wellington Management Company, LLP.LLP, Insight North America LLC, MacKay Shields LLC and Wasmer, Schroeder & Company, LLC. The performance of the Company's invested assets is subject to the ability of the investment managers to select and manage appropriate investments. The Company's investment managers have discretionary authority over the Company's investment portfolio within the limits of the Company's investment guidelines approved by the Company's Board. The Company's portfolio is allocated approximately equally among the four investment managers and eachEach manager is compensated based upon a fixed percentage of the market value of the portion of the portfolio

being managed by such manager. BlackRock Financial Management, Inc. and Wellington Management Company LLP both own more than 5% of the Company's common shares, and the Company has a minority interest in Wasmer, Schroeder & Company, LLC. During the years ended December 31, 2016, 20152018, 2017 and 2014,2016, the Company recorded investment management feefees and related expenses of $9 million, $10$9 million, and $9 million, respectively.

As of December 31, 2016,2018, the Company internally managed 17%11% of the investment portfolio (excluding short-term investments), either in connection with its loss mitigation or risk management strategy, or because the Company believes a particular security or asset presents an attractive investment opportunity.

The largest component of the Company’s internally managed portfolio consists of obligations that the Company purchases in connection with its loss mitigation or risk management strategy for its insured exposure. The Company also holds other invested assets that were obtained or purchased as part of negotiated settlements with insured counterparties or under the terms of its financial guaranties. The Company held approximately $1,190 million and $1,251 million of securities, based on

their fair value after elimination of the benefit of any insurance provided by the Company, that were obtained for loss mitigation or risk management purposes in its internally managed investment accounts as of December 31, 2018 and December 31, 2017, respectively.

Another component of the Company's internally managed portfolio consists of alternative investments. Such investments include various funds investing in both equity and debt securities as well as investments in investment managers. During 2016, the Company established an alternative investments group to focus on deploying a portion of the Company's excess capital to pursue acquisitions and develop new business opportunities that complement the Company's financial guaranty business, are in line with its risk profile and benefit from its core competencies. The alternative investments group has been investigating a number of such opportunities including both controlling and non-controlling investments in investment managers.

The largest component of the Company’s internally managed portfolio consists of obligations that In February 2017 the Company purchasesagreed to purchase up to $100 million of limited partnership interests in connection with its loss mitigation or risk management strategy for its insured exposure. Purchasing such obligations enablesa fund that invests in the equity of private equity managers. In September 2017 the Company to exercise rights available to holdersacquired a minority interest in Wasmer, Schroeder & Company LLC, an independent investment advisory firm specializing in SMAs. In February 2018, the Company acquired a minority interest in the holding company of Rubicon Infrastructure Advisors, a full-service investment firm based in Dublin that provides investment banking services within the obligations.global infrastructure sector. The Company also holds other invested assets that were obtainedcontinues to investigate additional opportunities to make alternative investments, including, among others, both controlling and non-controlling investments in investment managers, but there can be no assurance if or purchased as part of negotiated settlements with insured counterparties or under the terms of its financial guaranties. The Company held approximately $1,600 million and $1,440 million of securities based on their fair value, after elimination of the benefit of any insurance provided bywhen the Company that were obtained for loss mitigation or risk management purposes in its internally managed investment accounts as of December 31, 2016 and December 31, 2015, respectively.will find suitable opportunities on appropriate terms.

Competition

Assured Guaranty is the market leader in the financial guaranty industry. Assured Guaranty believes its financial strength, protection against defaults, credit selection policies, underwriting standards, history of making claim payments and surveillance procedures make it an attractive provider of financial guaranties.
    
Assured Guaranty's principal competition is in the form of obligations that issuers decide to issue on an uninsured basis. In the U.S. public finance market, when interest rates are low, investors may prefer greater yield over insurance protection, and issuers may find the cost savings from insurance less compelling. Over the last several years, interest rates generally have been lower than historical norms. Average municipal interest rates were extremelyin 2018, while above the historic lows experienced in 2016 and slightly above the average rates experienced in 2017, remained low during 2016, with the benchmark AAA 30-year Municipal Market Data index published by Thomson Reuters (MMD Index), at times below 2%, a threshold not previously crossed in the modern era.when compared to historical norms. As a result, the difference in yield (or the credit spread) between a bond insured by Assured Guaranty and an uninsured bond has provided comparatively little room for issuer savings and insurance premium. In the U.S. public finance market in 2016,2018, market penetration of municipal bond insurance decreasedincreased to approximately 6.0%5.9% of the par amount of new issues sold, compared with approximately 6.7%5.6% in 2015.2017. The Company believes this decrease wasthe relatively low market penetration rates in 2018 and 2017 were in part due in large part to the extremely low interest rates prevailing during most of 2016.that period.

In the international infrastructureU.S. public finance market, the uninsured execution serving as the Company’s principal competition occurs primarily in privately funded transactions where no bonds are sold in the public markets. In the structured finance market, the uninsured execution occurs in both public and primary transactions primarily where bonds are sold with sufficient credit or structural enhancement embedded in transactions, such as through overcollateralization, first loss insurance, excess spread or other terms, to make the bonds attractive to investors without bond insurance.     
Assured Guaranty is the only financial guaranty company active before the global financial crisis of 2008 that has maintained sufficient financial strength to write new business continuously since the crisis began. As a result of rating agency downgrades of the financial strength ratings of financial guaranty competitors active before the crisis, Assured Guaranty has only twoone direct competitorscompetitor for financial guaranty in the most significant of which waspublic finance market, BAM, a mutual insurance company that commenced business in 2012.

Based on industry statistics, the Company estimates that, of the new U.S. public finance bonds sold with insurance in 2016,2018, the Company insured approximately 56% of the par, while BAM insured approximately 40%44%. BAM is effective in competing with the Company for small to medium sized U.S. public finance transactions in certain sectors. BAM sometimes prices its guarantees for such transactions at levels the Company does not believe produces an adequate rate of return and so does not match, but BAM's pricing and underwriting strategies may have a negative impact on the amount of premium the Company is able to charge for its insurance for such transactions. However, the Company believes it has competitive advantages over BAM due to: AGM's and MAC's larger capital base; AGM's ability to insure larger transactions and issuances in more diverse U.S. bond sectors; BAM's inability to date to generate profits and to increase its statutory capital meaningfully, its higher leverage ratios than those of AGM and MAC, and its increasing unpaid debt obligations; and AGM's and MAC's strong financial strength ratings from multiple rating agencies (in the case of AGM, AA+ from KBRA, AA from S&P and A2

from Moody's, and in the case of MAC, AA+ from KBRA and AA from S&P, compared with BAM's AA solely from S&P). Additionally, as a public company with access to both the equity and debt capital markets, Assured Guaranty may have greater flexibility to raise capital, if needed.
Another competitor to the Company on U.S. public finance transactions is National, which the Company estimates insured approximately 4% of the par of public finance bonds sold with insurance in 2016. In 2009, MBIA, one of the legacy insurers that is not writing new business, transferred its U.S. public finance exposures to its affiliate National. The transfer was challenged in litigation that was not settled until May 2013. Subsequently, S&P has raised National’s financial strength rating from BBB to AA-, noting that S&P no longer viewed MBIA’s rating as a limitation on National’s rating, and Moody’s has upgraded National's financial strength rating from Baa2 to A3.
    
In the global structured finance and infrastructure markets, Assured Guaranty is the only financial guaranty insurance company currently writing new guarantees. Management considers the Company’s greater diversification to be a competitive advantage in the long run because it means the Company is not wholly dependent on conditions in any one market. In the international infrastructure finance market, the uninsured execution serving as the Company’s principal competition occurs

primarily in privately funded transactions where no bonds are sold in the public markets. In the structured finance market, the uninsured execution occurs in both public and primary transactions primarily where bonds are sold with sufficient credit or structural enhancement embedded in transactions, such as through overcollateralization, first loss insurance, excess spread or other terms, to make the bonds attractive to investors without bond insurance.
    
In the future, additional new entrants into the financial guaranty industry could reduce the Company's new business prospects, including by furthering price competition or offering financial guaranty insurance on transactions with structural and security features that are more favorable to the issuers than those required by Assured Guaranty. However, the Company believes that the presence of multiple guarantors might also increase the overall visibility and acceptance of the product by a broadening group of investors, and the fact that investors are willing to commit fresh capital to the industry may promote market confidence in the product.
    
In addition to monoline insurance companies, Assured Guaranty competes with other forms of credit enhancement, such as letters of credit or credit derivatives provided by banks and other financial institutions, some of which are governmental enterprises, or direct guaranties of municipal, structured finance or other debt by federal or state governments or government sponsored or affiliated agencies. Alternative credit enhancement structures, and in particular federal government credit enhancement or other programs, can interfere with the Company's new business prospects, particularly if they provide direct governmental-level guaranties, restrict the use of third-party financial guaranties or reduce the amount of transactions that might qualify for financial guaranties.

Regulation

General

The business of insurance and reinsurance is regulated in most countries, although the degree and type of regulation varies significantly from one jurisdiction to another. Reinsurers are generally subject to less direct regulation than primary insurers. The Company is subject to regulation under applicable statutes in the U.S., the U.K. and Bermuda, as well as applicable statutes in Australia.Bermuda.

United States

AGL has three operating insurance subsidiaries domiciled in the U.S., which the Company refers to collectively as the Assured Guaranty U.S. Insurance Subsidiaries.

AGM is a New York domiciled insurance company licensed to write financial guaranty insurance and reinsurance in 50 U.S. states, the District of Columbia, Guam, Puerto Rico and the U.S. Virgin Islands.

MAC is a New York domiciled insurance company licensed to write financial guaranty insurance and reinsurance in 50 U.S. states and the District of Columbia. MAC will only insureinsures U.S. public finance debt obligations, focusing on investment grade bonds in select sectors of that market.

AGC is a Maryland domiciled insurance company licensed to write financial guaranty insurance and reinsurance in 50 U.S. states, the District of Columbia and Puerto Rico.
Insurance Holding Company Regulation

AGL and the Assured Guaranty U.S. Insurance Subsidiaries are subject to the insurance holding company laws of their jurisdictionrespective jurisdictions of domicile, as well as other jurisdictions where these insurers are licensed to do insurance business. These laws

generally require each of the Assured Guaranty U.S. Insurance Subsidiaries to register with its respective domestic state insurance department and annually to furnish financial and other information about the operations of companies within theirits holding company system. Generally, all transactions among companies in the holding company system to which any of the Assured Guaranty U.S. Insurance Subsidiaries is a party (including sales, loans, reinsurance agreements and service agreements) must be fair and, if material or of a specified category, such as reinsurance or service agreements, require prior notice and approval or non-disapproval by the insurance department where the applicable subsidiary is domiciled.


Change of Control

Before a person can acquire control of a U.S. domestic insurance company, prior written approval must be obtained from the insurance commissioner of the state where the domestic insurer is domiciled. Generally, state statutes provide that control over a domestic insurer is presumed to exist if any person, directly or indirectly, owns, controls, holds with the power to vote, or holds proxies representing, 10% or more of the voting securities of the domestic insurer. Prior to granting approval of an application to acquire control of a domestic insurer, the state insurance commissioner will consider factors such factors as the financial strength of the applicant, the integrity and management of the applicant's board of directors and executive officers, the acquirer's plans for the management of the applicant's board of directors and executive officers, the acquirer's plans for the future operations of the domestic insurer and any anti-competitive results that may arise from the consummation of the acquisition of control. These laws may discourage potential acquisition proposals and may delay, deter or prevent a change of control involving AGL that some or all of AGL's stockholders might consider to be desirable, including in particular unsolicited transactions.

State Insurance Regulation

State insurance authorities have broad regulatory powers with respect to various aspects of the business of U.S. insurance companies, including licensing these companies to transact business, accreditation of reinsurers, admittance ofdetermining whether assets toare "admitted" and counted in statutory surplus, regulatingprohibiting unfair trade and claims practices, establishing reserve requirements and solvency standards, regulating investments and dividends and, in certain instances, approving policy forms and related materials and approving premium rates. State insurance laws and regulations require the Assured Guaranty U.S. Insurance Subsidiaries to file financial statements with insurance departments everywhere they are licensed, authorized or accredited to conduct insurance business, and their operations are subject to examination by those departments at any time. The Assured Guaranty U.S. Insurance Subsidiaries prepare statutory financial statements in accordance with Statutory Accounting Practices,Principles, or SAP, and procedures prescribed or permitted by these departments. State insurance departments also conduct periodic examinations of the books and records, financial reporting, policy filings and market conduct of insurance companies domiciled in their states, generally once every three to five years. Market conduct examinations by regulators other than the domestic regulator are generally carried out in cooperation with the insurance departments of other states under guidelines promulgated by the National Association of Insurance Commissioners.

The New York State Department of Financial Services (the NYDFS), the regulatory authority of the domiciliary jurisdiction of AGM and MAC, and the Maryland Insurance Administration (the MIA), the regulatory authority of the domiciliary jurisdiction of AGC, each conducts a periodic examination of insurance companies domiciled in New York and Maryland, respectively, usually at five-year intervals. In 2012, the NYDFS commenced examinations of AGM and MAC in order for its examinations of these companies to coincide with the Maryland Insurance Administration (the MIA's) examination of AGC. In 2013, the NYDFS completed its examinations and issued Reports on Examination of AGM for the four-year period ending December 31, 2011 and MAC for the period September 26, 2008 through June 30, 2012. The reports did not note any significant regulatory issues concerning those companies.

The MIA, the regulatory authority of the domiciliary jurisdiction of AGC, conducts a periodic examination of insurance companies domiciled in Maryland every five years. In 2013, the MIA issued an Examination Report with respect to AGC for the five year period ending December 31, 2011; no significant regulatory issues were noted in such report.

Assured Guaranty has been notified that2017, the NYDFS and MIA will formally commence an examination,in coordination commenced examinations, respectively, of AGM and MAC, and AGC, in 2017 for the period covering the end of the last applicable examination period for each company through December 31, 2016. In 2018, the NYDFS and MIA completed their examinations. The NYDFS issued Reports on Examination of AGM for the five-year period ending December 31, 2016 and MAC for the period July 1, 2012 through December 31, 2016. The reports did not note any significant regulatory issues concerning those companies. The MIA issued an Examination Report with respect to AGC for the five year period ending December 31, 2016; no significant regulatory issues were noted in that report.

State Dividend Limitations

New York.    One of the primary sources of cash for repurchases of shares and the payment of debt service and dividends by the Company is the receipt of dividends from AGM. Under the New York Insurance Law, AGM and MAC may only pay dividends out of "earned surplus," which is the portion of the company's surplus that represents the net earnings, gains or profits (after deduction of all losses) that have not been distributed to shareholders as dividends, transferred to stated capital

or capital surplus, or applied to other purposes permitted by law, but does not include unrealized appreciation of assets. AGM and MAC may each pay dividends without the prior approval of the New York Superintendent of Financial Services (New York Superintendent) that, together with all dividends declared or distributed by it during the preceding 12 months, do not exceed the lesser of 10% of its policyholders' surplus (as of its last annual or quarterly statement filed with the New York Superintendent) or 100% of its adjusted net investment income during that period. TheSee Part II, Item 7, Management's Discussion and Analysis, Liquidity and Capital Resources, for the maximum amount available during 2017 for AGM to payof dividends to its parent AGMHthat can be paid without regulatory approval, is estimated to be approximately $232 million, of which approximately $81 million is available for distribution in the first quarter of 2017. AGM paid dividends of $247 million, $215 millionrecent dividend history and $160 million during 2016, 2015 and 2014, respectively, to AGMH. The maximum amount available during 2017 for MAC to distribute as dividends to its shareholders (AGM and AGC) without regulatory approval is estimated to be approximately $49 million; MAC currently intends to allocate the distribution of such amount quarterly in 2017. other recent capital movements.

Maryland.    Another primary source of cash for the repurchases of shares and payment of debt service and dividends by the Company is the receipt of dividends from AGC. Under Maryland's insurance law, AGC may, with prior notice to the MIA, pay an ordinary dividend that, together with all dividends paid in the prior 12 months, does not exceed the lesser of 10% of its policyholders' surplus (as of the prior December 31) or 100% of its adjusted net investment income during that period. The maximum amount available during 2017 for AGC to pay ordinary dividends to its parent Assured Guaranty U.S. Holdings Inc. (AGUS) will be approximately $107 million, of which approximately $29 million is available for distribution in the first quarter of 2017. A dividend or distribution to a stockholder in excess of this limitation would constitute an "extraordinary dividend," which must

be paid out of "earned surplus" and reported to, and approved by, the MIA prior to payment. "Earned surplus" is that portion of the company's surplus that represents the net earnings, gains or profits (after deduction of all losses) that have not been distributed to shareholders as dividends or transferred to stated capital or capital surplus, or applied to other purposes permitted by law, but does not include unrealized capital gains and appreciation of assets. AGC may not pay any dividend or make any distribution, including ordinary dividends, unless it notifies the MIAMaryland Insurance Commissioner (the Maryland Commissioner) of the proposed payment within five business days following declaration and at least ten days before payment. The MIAMaryland Commissioner may declare that such dividend not be paid if it finds that AGC's policyholders' surplus would be inadequate after payment of the dividend or the dividend could lead AGC to a hazardous financial condition. AGCSee Part II, Item 7, Management's Discussion and Analysis, Liquidity and Capital Resources, for the maximum amount of dividends that can be paid dividends of $79 million, $90 millionwithout regulatory approval, recent dividend history and $69 million during 2016, 2015 and 2014, respectively, to AGUS.other recent capital movements.

Contingency Reserves

Under the New York Insurance Law, each of AGM and MAC must establish a contingency reserve to protect policyholders. New York Insurance Law determines the calculation of the contingency reserve and the period of time over which it must be established and, subsequently, can be taken down.released.

Likewise, in accordance with Maryland insurance law and regulations, AGC also maintains a statutory contingency reserve for the protection of policyholders. Maryland insurance law determines the calculation of the contingency reserve and the period of time over which it must be established, and subsequently, can be taken down.released.
 
In both New York and Maryland, when considering the principal amount guaranteed, the insurer is permitted to take into account amounts that it has ceded to reinsurers. In addition, releases from the insurer's contingency reserve may be permitted under specified circumstances in the event that actual loss experience exceeds certain thresholds or if the reserve accumulated is deemed excessive in relation to the insurer's outstanding insured obligations.

From time to time, AGM and AGC have obtained the approval of their regulators to release contingency reserves based on losses or because the accumulated reserve is deemed excessive in relation to the insurer's outstanding insured obligations. In 2016,2018, on the latter basis, AGM obtained the NYDFS's approval for a contingency reserve release of approximately $175$142 million and AGC obtained the MIA's approval for a contingency reserve release of approximately $152$11 million. In 2017, AGM obtained the NYDFS's approval for a contingency reserve release of approximately $246 million and AGC obtained the MIA's approval for a contingency reserve release of approximately $134 million. In addition, MAC also released approximately $53$45 million and $62 million of contingency reserves in 2018 and 2017, respectively, which consisted of the assumed contingency reserves maintained by MAC, as reinsurer of AGM, in respect of the same obligations that were the subject of AGM's $175$142 million release.and $246 million releases in 2018 and 2017, respectively.

Applicable Maryland and New York laws and regulations require regular, quarterly contributions to contingency reserves, while they are being established, but such laws and regulations permit the discontinuation of such quarterly contributions to an insurer's contingency reserves when such insurer's aggregate contingency reserves for a particular line of business (i.e., municipal or non-municipal) exceed the sum of the insurer's outstanding principal for each specified category of obligations within the particular line of business multiplied by the specified contingency reserve factor for each such category.  In accordance with such laws and regulations, and with the approval of the MIA and the NYDFS, respectively, AGC ceased making quarterly contributions to its contingency reserves for both municipal and non-municipal business and AGM ceased making quarterly contributions to its contingency reserves for non-municipal business, in each case beginning in the fourth

quarter of 2014. Such cessations are expected to continue for as long as AGC and AGM satisfy the foregoing condition for their applicable line(s) of business.

In July 2013, AGM and AGC were notified that the NYDFS and MIA did not object to AGM, AGE and AGC reassuming all of the outstanding contingency reserves that they had ceded to AG Re and electing to cease ceding future contingency reserves to AG Re. The insurance regulators permitted AGM, AGE and AGC to reassume the contingency reserves in increments over three years. As of December 31, 2015, AGM, AGE and AGC had collectively reassumed an aggregate of approximately $522 million.

Financial guaranty insurers are also required to maintain a loss and loss adjustment expense (LAE) reserve (on a case-by-case basis) and unearned premium reserve.

Single and Aggregate Risk Limits

The New York Insurance Law and the Code of Maryland Regulations establish single risk limits for financial guaranty insurers applicable to all obligations issued by a single entity and backed by a single revenue source. For example, under the limit applicable to municipal obligations, the insured average annual debt service for a single risk, net of qualifying reinsurance and collateral, may not exceed 10% of the sum of the insurer's policyholders' surplus and contingency reserves. In addition, insured principal of municipal obligations attributable to any single risk, net of qualifying reinsurance and collateral, is limited to 75% of the insurer's policyholders' surplus and contingency reserves.


Under the limit applicable to qualifying asset-backed securities, the lesser of:

the insured average annual debt service for a single risk, net of qualifying reinsurance and collateral, or

the insured unpaid principal (reduced by the extent to which the unpaid principal of the supporting assets exceeds the insured unpaid principal) divided by nine, net of qualifying reinsurance and collateral,

may not exceed 10% of the sum of the insurer's policyholders' surplus and contingency reserves, subject to certain conditions.

Under the limit applicable to municipal obligations, the insured average annual debt service for a single risk, net of qualifying reinsurance and collateral, may not exceed 10% of the sum of the insurer's policyholders' surplus and contingency reserves. In addition, insured principal of municipal obligations attributable to any single risk, net of qualifying reinsurance and collateral, is limited to 75% of the insurer's policyholders' surplus and contingency reserves. Single-risk limits are also specified for other categories of insured obligations, and generally are more restrictive than those listed for asset-backed or municipal obligations. Obligations not qualifying for an enhanced single-risk limit are generally subject to the "corporate" limit (applicable to insurance of unsecured corporate obligations) equal to 10% of the sum of the insurer's policyholders' surplus and contingency reserves. For example, "triple-X" and "future flow" securitizations, as well as unsecured investor-owned utility obligations, are generally subject to these "corporate" single-risk limits.

The New York Insurance Law and the Code of Maryland Regulations also establish aggregate risk limits on the basis of aggregate net liability insured as compared with statutory capital. "Aggregate net liability" is defined as outstanding principal and interest of guaranteed obligations insured, net of qualifying reinsurance and collateral. Under these limits, policyholders' surplus and contingency reserves must not be less than the sum of various percentages of aggregate net liability for various categories of specified obligations. The percentage varies from 0.33% for certain municipal obligations to 4% for certain non-investment-grade obligations. As of December 31, 2016,2018, the aggregate net liability of each of AGM, MAC and AGC utilized approximately 23.7%22%, 27.6%22% and 10.7%10% of their respective policyholders' surplus and contingency reserves.

The New York Superintendent hasand the Maryland Commissioner each have broad discretion to order a financial guaranty insurer to cease new business originations if the insurer fails to comply with single or aggregate risk limits. In practice,the Company's experience in New York, the New York Superintendent has shown a willingness to work with insurers to address these concerns.

Group Regulation

In connection with AGL’s establishment of tax residence in the U.K., as discussed in greater detail under "Tax Matters" below, the NYDFS has assumed responsibilitybeen designated as group-wide supervisor for regulation of the Assured Guaranty group. GroupGroup-wide supervision by the NYDFS results in additional regulatory oversight over Assured Guaranty, particularly with respect to group-wide enterprise risk, and may subject Assured Guaranty to new regulatory requirements and constraints.


Investments

The Assured Guaranty U.S. Insurance Subsidiaries are subject to laws and regulations that require diversification of their investment portfolio and limit the amount of investments in certain asset categories, such as BIG fixed-maturity securities, equity real estate, other equity investments, and derivatives. Failure to comply with these laws and regulations would cause investments exceeding regulatory limitations to be treated as non-admitted assets for purposes of measuring surplus, and, in some instances, would require divestiture of such non-qualifying investments. The Company believes that the investments made by the Assured Guaranty U.S. Insurance Subsidiaries complied with such regulations as of December 31, 2016.2018. In addition, any investment must be approved by the insurance company's board of directors or a committee thereof that is responsible for supervising or making such investment.

Operations of the Company's Non-U.S. Insurance Subsidiaries

In addition to the regulatory requirements imposed by the jurisdictions in which they are licensed, the business operations of the Company's reinsurance subsidiaries are affected by regulatory requirements in various U.S. states ofgoverning the United States governing "credit for reinsurance", which are imposed onability of the ceding companies of the reinsurers.reinsurers to receive credit for the reinsurance on their financial statements. The Nonadmitted and Reinsurance Reform Act (NRRA) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act) streamlined the regulation of reinsurance by applying single state regulation for credit for reinsurance. Under the NRRA,Nonadmitted and Reinsurance Reform Act, credit for reinsurance determinations are controlled by the ceding company’s state of domicile and non-domiciliary states are prohibited from applying their reinsurance laws extraterritorially. In general, a ceding company which obtains reinsurance from a reinsurer that is licensed, accredited or approved by the ceding company's state of domicile is permitted to reflect in its statutory financial statements a credit in an aggregate amount equal to the ceding company's liability for unearned premiums (which are that portion of premiums written which applies to the unexpired portion of the policy period), and loss and loss adjustment expense reserves ceded to the reinsurer. The great majority of states,

however, also permit a credit on the statutory financial statements of a ceding insurer for reinsurance obtained from a non-licensed or non-accredited reinsurer to the extent that the reinsurer secures its reinsurance obligations to the ceding insurer by providing collateral in the form of a letter of credit, trust fund or other acceptable security arrangement. Certain of those states permit such non-licensed/non-accredited reinsurers that meet certain specified requirements to apply for certified reinsurer status. If granted, such status allows the certified reinsurer to post less than 100% collateral (the exact percentage depends on the certifying state's view of the reinsurer's financial strength) and the applicable ceding company will still qualify, on the basis of such reduced collateral, for full credit for reinsurance on its statutory financial statements with respect to reinsurance contracts renewed or entered into with the certified reinsurer on or after the date the reinsurer becomes certified. A few states do not allow credit for reinsurance ceded to non-licensed reinsurers except in certain limited circumstances and others impose additional requirements that make it difficult to become accredited. The Company's reinsurance subsidiaries AG Re and AGRO are not licensed, accredited or approved in any state and accordingly have established trusts to secure their reinsurance obligations. In 2017, AGRO obtained certified reinsurer status in Missouri, which allows AGRO to post 10% collateral in respect of any reinsurance assumed from Missouri-domiciled ceding companies on or after the date of AGRO’s certification. 

U.S. Federal Regulation

The Company’s businesses are subject to direct and indirect regulation under U.S. federal law. In particular, the Company’s derivatives activities are directly and indirectly subject to a variety of regulatory requirements under the Dodd-Frank Act. Based on the size of its subsidiaries' remaining legacy derivatives portfolios, AGL does not believe any of its subsidiaries is required to register with the Commodity Futures Trading Commission (CFTC) as a “major swap participant” or with the SECSecurities and Exchange Commission (SEC) as a "major securities-based swap participant".participant." Certain of the Company's subsidiaries may be subject to Dodd-Frank Act requirements to post margin or to clear on a regulated execution facility future swap transactions or with respect to certain amendments to legacy swap transactions, if they enter into such transactions.

Bermuda

AG Re and AGRO are each an insurance company currently registered and licensed under the Insurance Act 1978 of Bermuda, amendments thereto and related regulations (collectively, the Insurance Act). AG Re is registered and licensed as a Class 3B insurer and AGRO is registered and licensed as a Class 3A insurer and a Class C long-term insurer.

Bermuda Insurance Regulation

The Insurance Act imposes on insurance companies solvency and liquidity standards; restrictions on the declaration and payment of dividends and distributions; restrictions on the reduction of statutory capital; restrictions on the winding up of long-term insurers; and auditing and reporting requirements; and the need to have a principal representative and a principal office (as understood under the Insurance Act) in Bermuda. The Insurance Act grants to the Bermuda Monetary Authority (the Authority) the power to cancel insurance licenses, supervise, investigate and intervene in the affairs of insurance companies and in certain circumstances share information with foreign regulators. Class 3A and Class 3B insurers are authorized to carry on general insurance business (as understood under the Insurance Act), subject to conditions attached to the license and to compliance with minimum capital and surplus requirements, solvency margin, liquidity ratio and other requirements imposed by the Insurance Act. Class C long-term insurers are permitted to carry on long-term business (as understood under the

Insurance Act) subject to conditions attached to the license and to similar compliance requirements and the requirement to maintain its long-term business fund (a segregated fund).

Each of AG Re and AGRO is required annually to file statutorily mandated financial statements and returns, audited by an auditor approved by the Authority (no approved auditor of an insurer may have an interest in that insurer, other than as an insured, and no officer, servant or agent of an insurer shall be eligible for appointment as an insurer's approved auditor), together with an annual loss reserve opinion of the loss reserve specialist, who is approved by the Authority, and in respect of AGRO, the required actuary's certificate with respect to the long-term business. When each of AG Re and AGRO files its statutory financial statements, it is also required to deliver to the Authority a declaration of compliance, declaring whether or not the insurer has, with respect to the preceding financial year, complied with all requirements of the minimum criteria applicable to it; complied with the minimum margin of solvency as at its financial year end; complied with the applicable enhanced capital requirements as at its financial year end; complied with the minimum liquidity ratio for general business as at its financial year end; and complied with applicable conditions, directions and restrictions imposed on, or approvals granted to the insurer. AG Re and AGRO are also required to file annual financial statements prepared in conformity with accounting principles generally accepted in the United States of America (GAAP),GAAP, which must be available to the public.

In addition, AG Re and AGRO are each required to file a capital and solvency return that includes its Bermuda Solvency Capital Requirement (BSCR) model (or an approved internal capital model in lieu thereof), a schedule of fixed

income investments by BSCR rating, a schedule of funds held by ceding reinsurers in segregated accounts/trusts by BSCR rating, a schedule of net reserves for losses and loss expense provisions by line of business, a schedule of premiums written by line of business, a schedule of geographic diversification of net premiums written by line of business, a schedule of risk management, a schedule of fixed income securities, a schedule of commercial insurer's solvency self-assessment, (CISSA), a schedule of catastrophe risk return, a schedule of loss triangles or reconciliation of net loss reserves, a schedule of eligible capital, a statutory economic balance sheet, the loss reserve specialist's opinion, a schedule of regulated non-insurance financial operating entities and a schedule of solvency. AGRO’s capital and solvency return must also include, among other details, a schedule of long-term premiums written by line of business, a schedule of long-term business data, a schedule of long-term variable annuity guarantees data and reconciliation, a schedule of long-term variable annuity guarantees - internal capital model and the approved actuary’s opinion.

Each of AG Re and AGRO are also required to prepare and file with the Authority, and publish on its website, a financial condition report. The Authority has discretion to approve modifications and exemptions to the public disclosure rules, on application by the insurer if, among other things, the Authority is satisfied that the disclosure of certain information will result in a competitive disadvantage or compromise confidentiality obligations of the insurer.
        
Finally, in lieu of the standard legal and regulatory requirements, AG Re is required to filemake a modified filing with the Authority, on a quarterly basis, financial returns consisting of (i)its board of directors quarterly meeting package (which includes AG Re’s unaudited quarterly financial statements for each financial quarter (which must minimally include a balance sheet and income statement and must also be recent and not reflect a financial position that exceeds two months)statements), and (ii) a list and detailsno later than 30 days after the date of material intra‑group transactions and risk concentrations that have materialized since the most recentits quarterly or annual financial returns, which would also include, among other things, details surrounding all intra group reinsurance and retrocession arrangements and other intra group risk transfer insurance business arrangements that have materialized since the most recent quarterly or annual financial returns and (iii) details of the ten largest exposures to unaffiliated counterparties and any other counterparty exposures exceeding 10% of the insurer’s statutory capital and surplus.board meetings.
 
Shareholder Controllers

Pursuant to provisions in the Insurance Act, any person who becomes a holder of 10% or more, 20% or more, 33% or more or 50% or more of the Company's common shares must notify the Authority in writing within 45 days of becoming such a holder. The Authority has the power to object to such a person if it appears to the Authority that the person is not fit and proper to be such a holder. In such a case, the Authority may require the holder to reduce their shareholding in the Company and may direct, among other things, that the voting rights attached to their common shares are not exercisable. A person that does not comply with such a notice or direction from the Authority will be guilty of an offense.

Notification of Material Changes

All registered insurers are required to give notice to the Authority of their intention to effect a material change within the meaning of the Insurance Act. For the purposes of the Insurance Act, the following changes are material: (i) the transfer or acquisition of insurance business being part of a scheme falling within, or any transaction relating to a scheme of arrangement under section 25 of the Insurance Act or section 99 of the Companies Act 1981 of Bermuda (the Companies Act), (ii) the

amalgamation or merger with or acquisition of another firm, (iii)  engaging in unrelated business that is retail business, (iv) the acquisition of a controlling interest in an undertaking that is engaged in non-insurance business which offers services or products to non-affiliated persons, (v) outsourcing all or substantially all of the functions of actuarial, risk management, compliance and internal audit functions, (vi) outsourcing all or a material part of an insurer's underwriting activity, (vii) transferring other than by way of reinsurance all or substantially all of a line of business, (viii) expanding into a material new line of business, (ix) the sale of an insurer, and (x) outsourcing an officer role (in this context meaning a chief executive or senior executive performing the roles of underwriting, actuarial, risk management, compliance, internal audit, finance or investment matters).

Registered insurers are not permitted to take any steps to give effect to a material change listed above unless it has first served notice on the Authority that it intends to effect such material change and, before the end of 30 days, either the Authority has notified such company in writing that it has no objection to such change or that period has lapsed without the Authority having issued a notice of objection. A person who fails to give the required notice or who effects a material change, or allows such material change to be effected, before the prescribed period has elapsed or after having received a notice of objection is guilty of an offence.offense.

Minimum Solvency Margin and Enhanced Capital Requirements

Under the Insurance Act, AG Re and AGRO must each ensure that the value of its general business statutory assets exceeds the amount of its general business statutory liabilities by an amount greater than the prescribed minimum solvency margin and each company's applicable enhanced capital requirement.


The minimum solvency margin for Class 3A and Class 3B insurers is the greater of (i) $1 million, or (ii) 20% of the first $6 million of net premiums written; if in excess of $6 million, the figure is $1.2 million plus 15% of net premiums written in excess of $6 million, or (iii) 15% of net discounted aggregate loss and loss expense provisions and other insurance reserves, or (iv) 25% of that insurer's applicable enhanced capital requirement reported at the end of its relevant year.

In addition, as a Class C long-term insurer, AGRO is required, with respect to its long-term business, to maintain a minimum solvency margin equal to the greater of (i) $500,000, (ii) 1.5% of its assets or (iii) 25% its enhanced captialcapital requirement reported at the end of the relevant year. For the purpose of this calculation, assets are defined as the total assets pertaining to its long-term business reported on the balance sheet in the relevant year less the amounts held in a segregated account. AGRO is also required to keep its accounts in respect of its long-term business separate from any accounts kept in respect of any other business and all receipts of its long-term business form part of its long-term business fund.

Each of AG Re and AGRO is required to maintain available statutory capital and surplus at a level equal to or in excess of its applicable enhanced capital requirement, which is established by reference to either its BSCR model or an approved internal capital model. The BSCR model is a risk-based capital model which provides a method for determining an insurer's capital requirements (statutory economic capital and surplus) by taking into account the risk characteristics of different aspects of the insurer's business. The BSCR formula establishes capital requirements for ten categories of risk: fixed income investment risk, equity investment risk, interest rate/liquidity risk, currency risk, concentration risk, premium risk, reserve risk, credit risk, catastrophe risk and operational risk. For each category, the capital requirement is determined by applying factors to asset, premium, reserve, creditor, probable maximum loss and operation items, with higher factors applied to items with greater underlying risk and lower factors for less risky items.

While not specifically referred to in the Insurance Act, the Authority has also established a target capital level (TCL) for each insurer subject to an enhanced capital requirement equal to 120% of its enhanced capital requirement. While such an insurer is not currently required to maintain its statutory capital and surplus at this level, the TCL serves as an early warning tool for the Authority and failure to maintain statutory capital at least equal to the TCL will likely result in increased regulatory oversight.

For each insurer subject to an enhanced capital requirement, there is a three-tiered capital system designed to assess the quality of capital resources that a company has available to meet its capital requirements. Under this system, all of an insurer's capital instruments will be classified as either basic or ancillary capital which in turn will be classified into one of three tiers based on their “loss absorbency” characteristics. Highest quality capital is classified as Tier 1 Capital; lesser quality capital is classified as either Tier 2 Capital or Tier 3 Capital. Under this regime, up to certain specified percentages of Tier 1, Tier 2 and Tier 3 Capital (determined by registration classification) may be used to support the company's minimum solvency margin, enhanced capital requirement and TCL.


Restrictions on Dividends and Distributions

The Insurance Act limits the declaration and payment of dividends and other distributions by AG Re and AGRO.
Under the Insurance Act:

The minimum share capital must be always issued and outstanding and cannot be reduced. For AG Re, which is registered as a Class 3B insurer, the minimum share capital is $120,000. For AGRO, which is registered both as a Class 3A and a Class C long-term insurer, the minimum share capital is $370,000.

With respect to the distribution (including repurchase of shares) of any share capital, contributed surplus or other statutory capital:

(a)any such distribution that would reduce AG Re's or AGRO's total statutory capital by 15% or more of their respective total statutory capital as set out in their previous year's financial statements requires the prior approval of the Authority. Any application for such approval must include an affidavit stating that the company will continue to meet the required margins and such other information as the Authority may require; and

(b)as a Class C long-term insurer, AGRO may not use the funds allocated to its long-term business fund, directly or indirectly, for any purpose other than a purpose of its long-term business except in so far as such payment can be made out of any surplus certified by AGRO's approved actuary to be available for distribution otherwise than to policyholders;policyholders.


With respect to the declaration and payment of dividends:

(a)each of AG Re and AGRO is prohibited from declaring or paying any dividends during any financial year if it is in breach of its solvency margin, minimum liquidity ratio or enhanced capital requirement, or if the declaration or payment of such dividends would cause such a breach (if it has failed to meet its minimum solvency margin or minimum liquidity ratio on the last day of any financial year, the insurer will be prohibited, without the approval of the Authority, from declaring or paying any dividends during the next financial year). Dividends are paid out of each insurer's statutory surplus and, therefore, dividends cannot exceed such surplus. See "—Minimum Solvency Margin and Enhanced Capital Requirements" above and "—Minimum Liquidity Ratio" below;

(b)an insurer which at any time fails to meet its minimum solvency margin or comply with the enhanced capital requirement may not declare or pay any dividend until the failure is rectified, and also in such circumstances the insurer must report, within 14 days after becoming aware of its failure or having reason to believe that such failure has occurred, to the Authority in writing giving particulars of the circumstances leading to the failure and giving a plan detailing the manner, specific actions to be taken and time frame in which the insurer intends to rectify the failure. A failure to comply with the enhanced capital requirement will also result in the insurer furnishing certain other information to the Authority within 45 days after becoming aware of its failure or having reason to believe that such failure has occurred;

(c)each of AG Re and AGRO is prohibited from declaring or paying in any financial year dividends of more than 25% of its total statutory capital and surplus (as shown on its previous financial year's statutory balance sheet) unless it files (at least seven days before payments of such dividends) with the Authority an affidavit signed by at least two directors (one of whom must be a Bermuda resident director if any of the insurer's directors are resident in Bermuda) and the principal representative stating that it will continue to meet its solvency margin and minimum liquidity ratio. Where such an affidavit is filed, it shall be available for public inspection at the offices of the Authority; and

(d)as a Class C long-term insurer, AGRO may not declare or pay a dividend to any person other than a policyholder unless the value of the assets of its long-term business fund, as certified by AGRO's approved actuary, exceeds the extent (as so certified) of the liabilities of AGRO's long-term business, and the amount of any such dividend shall not exceed the aggregate of (1) that excess; and (2) any other funds properly available for the payment of dividends being funds arising out of AGRO's business other than its long-term business.


The Companies Act also limits the declaration and payment of dividends and other distributions by Bermuda companies such as AGL and its Bermuda subsidiaries, (includingwhich consist of AG Re, AGRO and AGRO)Cedar Personnel Ltd. (Bermuda Subsidiaries). Such companies may only declare and pay a dividend or make a distribution out of contributed surplus (as understood under the Companies Act) if there are reasonable grounds for believing that the company is and after the payment will be able to meet and pay its liabilities as they become due and the realizable value of the company's assets will not be less than its liabilities. The Companies Act also regulates and restricts the reduction and return of capital and paid in share premium, including the repurchase of shares.

Based on See Part II, Item 8, Financial Statements and Supplementary Data, Note 11, Insurance Company Regulatory Requirements, for more information, for the limitations above, in 2017 AG Re has the capacity to (i) make capital distributions in an aggregate amount up to $128 million without the prior approval of the Authority and (ii) declare and pay dividends in an aggregate amount up to the limit of its outstanding statutory surplus, which is $314 million. Such dividend capacity may be further limited by the actualmaximum amount of AG Re’s unencumbered assets, which amount changes from time to time due in part to collateral posting requirements. As of December 31, 2016, AG Re had unencumbered assets of approximately $596 million. AG Re declareddividends that can be paid without regulatory approval, recent dividend history and paid dividends of $100 million, $150 million and $82 million during 2016, 2015 and 2014, respectively, to AGL. The Company does not expect AGRO to declare or pay any dividends or other distributions at this time.recent capital movements.

Minimum Liquidity Ratio

The Insurance Act provides a minimum liquidity ratio for general business. An insurer engaged in general business is required to maintain the value of its relevant assets at not less than 75% of the amount of its relevant liabilities. Relevant assets include cash and time deposits, quoted investments, unquoted bonds and debentures, first liens on real estate, investment income due and accrued, accounts and premiums receivable, reinsurance balances receivable, funds held by ceding reinsurers and any other assets which the Authority on application in any particular case made to it with reasons, accepts in that case. There are certain categories of assets which, unless specifically permitted by the Authority, do not automatically qualify as relevant assets, such as unquoted equity securities, investments in and advances to affiliates and real estate and collateral loans.

The relevant liabilities are total general business insurance reserves and total other liabilities less deferred income tax and sundry liabilities (by interpretation, those not specifically defined) and letters of credit, corporate guarantees and other instruments.


Insurance Code of Conduct

Each of AG Re and AGRO is subject to the Insurance Code of Conduct, which establishes duties, standards, procedures and sound business principles which must be complied with to ensure sound corporate governance, risk management and internal controls are implemented by all insurers registered under the Insurance Act. The Authority will assess an insurer's compliance with the Code of Conduct in a proportionate manner relative to the nature, scale and complexity of its business. Failure to comply with the requirements under the Insurance Code of Conduct will be a factor taken into account by the Authority in determining whether an insurer is conducting its business in a sound and prudent manner as prescribed by the Insurance Act. Such failure to comply with the requirements of the Insurance Code of Conduct could result in the Authority exercising its powers of intervention and investigation and will be a factor in calculating the operational risk charge applicable in accordance with the insurer's BSCR model or approved internal model.

Certain Other Bermuda Law Considerations

Although AGL is incorporated in Bermuda, it is classified as a non-resident of Bermuda for exchange control purposes by the Authority. Pursuant to its non-resident status, AGL may engage in transactions in currencies other than Bermuda dollars and there are no restrictions on its ability to transfer funds (other than funds denominated in Bermuda dollars) in and out of Bermuda or to pay dividends to U.S. residents who are holders of its common shares.

Under Bermuda law, "exempted" companies are companies formed for the purpose of conducting business outside Bermuda from a principal place of business in Bermuda. As an "exempted" company, AGL (as well as each of AG Re and AGRO) may not, without the express authorization of the Bermuda legislature or under a license or consent granted by the Minister of Finance (the Minister), participate in certain business and other transactions, including: (1) the acquisition or holding of land in Bermuda (except that held by way of lease or tenancy agreement which is required for its business and held for a term not exceeding 50 years, or which is used to provide accommodation or recreational facilities for its officers and employees and held with the consent of the Minister, for a term not exceeding 21 years), (2) the taking of mortgages on land in Bermuda to secure a principal amount in excess of $50,000 unless the Minister consents to a higher amount, and (3) the carrying on of business of any kind or type for which it is not duly licensed in Bermuda, except in certain limited circumstances, such as doing business with another exempted undertaking in furtherance of AGL's business carried on outside Bermuda.

The Bermuda government actively encourages foreign investment in "exempted" entities like AGL that are based in Bermuda, but which do not operate in competition with local businesses. AGL is not currently subject to taxes computed on profits or income or computed on any capital asset, gain or appreciation. Bermuda companies pay, as applicable, annual government fees, business fees, payroll tax and other taxes and duties. See "—Tax Matters—Taxation of AGL and Subsidiaries—Bermuda."

Special considerations apply to the Company's Bermuda operations. Under Bermuda law, non-Bermudians, other than spouses of Bermudians and individuals holding permanent resident certificates or working resident certificates, are not permitted to engage in any gainful occupation in Bermuda without a work permit issued by the Bermuda government. A work permit is only granted or extended if the employer can show that, after a proper public advertisement, no Bermudian, spouse of a Bermudian or individual holding a permanent resident certificate or working resident certificate is available who meets the minimum standards for the position. A waiver from advertising is automatically granted in respect of any chief executive officer position and other chief officer positions. The employer can also make a request for a waiver from the requirement to advertise in certain other cases, as expressed in the Bermuda government's work permit policies. Currently, all of the Company's Bermuda based professional employees who require work permits have been granted work permits by the Bermuda government.

United Kingdom

This section concerns AGE and its affiliates Assured Guaranty (U.K.) Ltd. (AGUK), Assured Guaranty (London) Ltd. (AGLN) and Assured Guaranty Finance Overseas Ltd (AGFOL), each of which is regulated in the U.K., as well as Assured Guaranty Credit Protection Ltd. (AGCPL), which is an authorized representative of AGE. AGE, AGUK and AGLN are regulated by the PRA as insurers. AGUK has been placed into runoff.AGLN (formerly MBIA UK Insurance Limited and renamed on January 13, 2017) was acquired as an authorized insurer in run-off by AGC on January 10, 2017. The Company is actively working to combinecombined the operations of its European subsidiaries, AGE, AGUK, AGLN and its affiliate CIFG Europe S.A. (CIFGE). Any such combination will be subjectCIFGE, in a transaction that was completed on November 7, 2018. Under the Combination, AGUK, AGLN and CIFGE transferred their insurance portfolios to regulatory and court approvals. As a result, the Company cannot predict when, or if, such combination will be completed.merged with and into AGE.

General

Each of AGE AGUK, AGLN and AGFOLAssured Guaranty Finance Overseas Ltd. (AGFOL) are subject to the U.K.'s Financial Services and Markets Act 2000 (FSMA), which covers financial services relating to deposits, insurance, investments and certain other financial products.

Under FSMA, effecting or carrying out contracts of insurance by way of business in the U.K. each constitutes a “regulated activity” requiring authorization by the appropriate regulator. An authorized insurance company must have permission for each class of insurance business it intends to write.
Insurance companies in the U.K. are authorized and regulated by the PRAPrudential Regulation Authority (PRA) and the Financial Conduct Authority (FCA). The PRA and the FCA were established on April 1, 2013 and are the main regulatory authorities responsible for financial regulation in the U.K. These two regulatory bodies cover the following areas:
the PRA, a part of the Bank of England, is responsible for prudential regulation of key systemically importantcertain classes of financial services firms (which includes insurance companies, among others), and
the FCA is responsible for the conduct of business regulation of all firms and the regulation of market conduct and the prudential regulation of all non-PRA firms.
While the two regulators coordinate and cooperate in some areas, they have separate and independent mandates and separate rule-making and enforcement powers. AGE AGUK and AGLN areis regulated by both the PRA and the FCA. AGFOL is regulated by the FCA.
The PRA carries out the prudential supervision of insurance companies through a variety of methods, including the collection of information from statistical returns, the review of accountants' reports and insurers' annual reports and disclosures, visits to insurance companies and regular formal interviews. The PRA takes a risk-based approach to the supervision of insurance companies.
The primary source of rules relating to the prudential supervision of AGE AGUK and AGLN is the Solvency II Directive (Directive 2009/138/EC) as amended (including by the Omnibus II Directive (Directive 2014/51/EU)) (together, Solvency II),

which came into force and effect on January 1, 2016. The PRA remains the prudential regulator for U.K. insurers such as AGE, AGUK and AGLN under Solvency II. Solvency II provides rules on capital adequacy, governance and risk management and regulatory reporting and public disclosure. It is intended to align capital requirements with the risk profile of each EEA insurance company and to ensure adequate diversification of an insurer's or reinsurer's exposures to any credit risks of its reinsurers. Each of AGE AGUK and AGLN has calculated its minimum required capital according to the Solvency II criteria and is in compliance.
 
The PRA applies threshold conditions, which insurers must meet, and against which the PRA assesses them on a continuous basis. At a high level, these conditions are that:
an insurer's head office, and in particular its mind and management, must be in the U.K. if it is incorporated in the U.K.;
an insurer's business must be conducted in a prudent manner — in particular, the insurer must maintain appropriate financial and non-financial resources;
the insurer must be fit and proper, and be appropriately staffed; and
the insurer and its group must be capable of being effectively supervised.
The PRA assesses, on an ongoing basis, whether insurers are acting in a manner consistent with safety and soundness and appropriate policyholder protection, and so whether they meet, and are likely to continue to meet, the threshold conditions. It weights its supervision towards those issues and those insurers that, in its judgment, pose the greatest risk to its objectives. It is forward-looking, assessing its objectives not just against current risks, but also against those that could plausibly arise further ahead and will rely significantly on judgments based on evidence and analysis. Its risk assessment framework looks at the potential impact of failure of the insurer, its risk context and mitigating factors.
AGFOL’sThe key European Union (EU) legislation that is relevant to AGFOL is the Markets in Financial Instruments Directive (MiFID)(Directive 2014/65/EU)(MiFID II), which harmonizes the regulatory regime for investment services and activities across the EEA and the Insurance Distribution Directive (Directive EU/2016/97)(which came into force on October 1, 2018). AGFOL’s MiFID II activities are limited to receiving and transmitting orders and giving investment advice and it cannot hold client money. Accordingly, although it is subject to MiFID II, AGFOL is exempt from the Capital Requirements Directive and Capital Requirements Regulations, (CRD III and CRD IV), which are the EU regulations on capital for certain MiFID firms. AGFOL has therefore calculated its minimum required capital according to the FCA’s rules for non-CRDnon-Capital Requirements Directive firms, and is in compliance.

TheCurrently, the regulatory regime in the U.K. must be consistent with relevant European Union (EU)EU legislation, which is either directly applicable in, or must be implemented into national law by, all EU member states. The key EU legislation that is relevant to AGE AGUK and AGLN is Solvency II, which provides the framework for a newthe solvency and supervisory regime for insurers in the EEA. The key EU legislation that is relevant to AGFOL is MiFID which harmonizes the regulatory regime for investment services and activities across the EEA and the Insurance Mediation Directive.II.
Position of U.K. Regulated Entities within the AGL Group
AGE is authorized by the PRA to effect and carry out certain classes of general insurance, specifically: classes 14 (credit), 15 (suretyship) and 16 (miscellaneous financial loss) for eligible counterparties and professional clients only (i.e., not retail clients). This scope of permission is sufficient to enable AGE to effect and carry out financial guaranty insurance and reinsurance. The insurance and reinsurance businesses of AGE are subject to close supervision by the PRA. AGE also has permission to arrange and advise on transactions it guarantees, and to take deposits in the context of its insurance business.
Following the Company's decision inIn 2010 to place AGUK into run-off, the Company has been utilizing AGE as the entity from which to write business in the EEA. Itit was agreed between management and AGE's then regulator, the Financial Services Authority (now the PRA), that any new business written by AGE would be guaranteed using a co-insurance structure pursuant to which AGE would co-insure municipal and infrastructure transactions with AGM, and structured finance transactions with AGC. AGE must obtain the approval of the PRA before it can guarantee any new structured finance transaction. AGE's financial guaranty for each transaction covers a proportionate share (expected to be approximately 3 to 10%(currently fixed from 2019 at 15%) of the total exposure, and AGM or AGC, as the case may be, guarantees the remaining exposure under the transaction (subject to compliance with EEA licensing requirements). AGM or AGC, as the case may be, will also provide a second-to-pay guaranty to cover AGE's financial guaranty.

AGE also is the principal of AGCPL.Assured Guaranty Credit Protection Ltd. (AGCPL). AGCPL is not PRA or FCA authorized, but is an appointed representative of AGE. This means AGCPL can carry on insurance mediation activities without a license, because AGE has regulatory responsibility for it.
AGCPL is subject to the requirements of Regulation (EU) No 648/2012 of the European Parliament and of the Council of July 4, 2012 on OTCover the counter (OTC) derivatives, central counterparties and trade repositories (EMIR) which, as a European regulation, is directly applicable in all the member states of the EU. AGCPL is the only European entity within the AGL group which has entered into derivative contracts and as such it is the only entity in the group which is directly subject to EMIR. AGCPL has notified the European Securities and Markets Authority (ESMA) and the FCA of its status under EMIR as a non-financial counterparty which has exceeded the clearing threshold (an NFC+) as described in Article 10 of EMIR. AGCPL is subject to certain requirements under EMIR with respect to its portfolio of derivative contracts including: (i) the requirement to centrally clear standardized OTC derivatives (although AGCPL does not currently enter into such derivatives, and so this requirement is not currently relevant); (ii) an obligation to employ certain risk mitigation techniques relating to derivatives that cannot be centrally cleared; and (iii) a requirement to report derivative transactions to a trade depository.repository.  The Company is aware that circumstances exist in which EMIR may apply directly to non-European entities when transacting derivatives, but has determined that these circumstances do not apply to the non-European entities in AGL’s group.
AGFOL, a subsidiary of AGL, is authorized by the FCA to carry out designated investment business activities (including insurance mediation)distribution) in that it may “advise on investments (except on pension transfers and pension opt outs)” relating to most investment instruments. In addition, it may arrange or bring about transactions in investments and make “arrangements with a view to transactions in investments.” In all cases, it may deal only with clients who are eligible counterparties or professional customers (i.e., not retail clients), or, when arranging in relation to non-investment insurance contracts, commercial customers. AGFOL is not authorized as an insurer and does not itself take risk in the transactions it arranges or places, and may not hold funds on behalf of its customers. AGFOL's permissions also allow it to introduce business to AGC and AGM, so that AGFOL can arrange financial guaranties underwritten by AGC and AGM.
Solvency II and Solvency Requirements
In the U.K., Solvency II has been transposed into national law through changes to existing provisions in the FCA and the PRA’s respective handbooks and rulebook and through amendments to primary legislation. The Solvency II “Delegated Acts”,Acts,” which set out more detailed rules underlying Solvency II have direct effect in all EEA member states, including the U.K. Among other things, Solvency II introducesintroduced a revised risk-based prudential regime which includes the following "Pillar 1" regulatory capital rules:
assets and liabilities are generally to be valued at their market value;
the amount of required economic capital is intended to ensure, with a probability of 99.5%, that regulated firms are able to meet their obligations to policyholders and beneficiaries over the following 12 months; and

reinsurance recoveries will be treated as a separate asset (rather than being netted against the underlying insurance liabilities).
In many instances, Solvency II is expected to require insurers to maintain a somewhat increased amount of capital to satisfy the new solvency capital requirements. AGE and AGUK havehas agreed with the PRA that theyit will use the "Standard Formula" prescribed by Solvency II for calculation of theirits capital requirements. AGLN is still using a bespoke internal model for calculation of its capital requirements, which was approved by the PRA prior to the acquisition of AGLN (then MBIA UK Insurance Limited) by AGC.
In addition to new regulatory capital rules, Solvency II also contains a number of “Pillar 2” qualitative requirements, obliging firms to develop and embed systems to identify, measure and proactively manage the risks they are, or may be, exposed to. Among other things, firms must:
have in place an effective system of governance that provides for the sound and prudent management of its business;
establish effective risk-management systems; and
take a comprehensive approach to considering their risks through an Own Risk and Solvency Assessment (ORSA) as proportionate to the nature, scale and complexity of the risks inherent in their business.
“Pillar 3” reporting and disclosure requirements also exist, including a requirement to publishprepare a public Solvency and Financial Condition Report (SFCR) and a private Regular Supervisory Report (RSR).Report. For more information on reporting requirements and the ORSA, see “Reporting Requirements” below.

Solvency II contains a new regime for the supervision of groups, including groups in which the parent undertaking has its head office in a country that is outside the EEA. The treatment of such groups in part depends on whether the jurisdiction in which the non-EEA parent has its head office is determined to have a supervisory regime which is equivalent to the Solvency II regime. In the absence of such a determination, the Solvency II rules on supervision apply to the group on a worldwide basis, unless the PRA elects to apply “other methods” which ensure appropriate supervision. Both AGE and AGUK are subsidiariesis a direct subsidiary of a U.S. parent companies.company.
The PRA has issued a Direction to AGE and AGUK which confirms the “other methods” that the PRA will apply to ensure appropriate supervision. These include, among other things, requirements for AGE and AGUK to notify the PRA in advance of any material changes in their intra-group arrangements and any payments of dividends or capital extractions to a group undertaking outside the EEA. AGE and AGUK must also provide the PRA with certain other information, such as internalin relation to the group's risk management, risk exposures and external solvency capital adequacy and risk assessment reports.assessment. The Direction applies from JanuaryNovember 12, 2018 until October 1, 2016 until January 1, 2019,2020, unless it is revoked earlier or no longer applicable.
Restrictions on Dividend Payments
U.K. company law prohibits each of AGE AGUK, AGLN and AGFOL from declaring a dividend to its shareholders unless it has “profits available for distribution.” The determination of whether a company has profits available for distribution is based on its accumulated realized profits less its accumulated realized losses. While the U.K. insurance regulatory laws impose no statutory restrictions on a general insurer's ability to declare a dividend, the PRA's capital requirements may in practice act as a restriction on dividends for AGE, AGUK and AGLN.AGE.
Reporting Requirements
U.K. insurance companies must prepare their financial statements under the Companies Act 2006, which requires the filing with Companies House of audited financial statements and related reports. In addition, as fromstarting January 1, 2016, the reporting requirements for U.K. insurance companies were modified by Solvency II. AGE AGUK and AGLN areis required to produce certain key reports including an annual SFCR, RSRSolvency and Financial Condition Report, Regular Supervisory Report and an ORSA, the latter as part of the so-called “Pillar 2” individual capital assessment requirements. Although the SFCR will take the place of a number of existing regulatory returns, Solvency II is likely to result in an overall increase in the quantity and quality of disclosures that firms make.
The PRA will review each firm’s ORSA and then consider whether in its view the firm needs to hold capital in excess of its Pillar 1 capital (see “Solvency II and Solvency Requirements” above) and, if so, willmay impose a “capital add-on”.add-on.” The prescribed information to be contained in the ORSA, as well as the frequency with which the assessment must be carried out, is subject to guidance issued by the European Insurance and Occupational Pensions Authority (EIOPA) in September 2015 and a supervisory statementstatements issued by the PRA in October 2015.PRA. The PRA has advised AGE AGUK and AGLN that it is not imposing a capital add-on for those companies at this time. The PRA may determine to impose a capital add-on in relation to AGE AGUK and AGLN in the future.
Supervision of Management
AGE AGUK and AGLN areis subject to the rules contained in the Senior Insurance Managers Regime (SIMR).and Certification Regime. This requires that individuals undertaking particular roles need to be registered with the PRA as undertaking a “Senior Insurance ManagerManagement Function”. This broadly includes individuals undertaking the executive functions and the oversight functions of each entity. DirectorsThere are also FCA senior

management functions and individuals who are performing roles which fall within one of those entities not serving in the roles specified in the SIMR will be required to become “approved persons” with the FCA (as detailed further in respect of AGFOL below).senior management functions need to be approved by the FCA.
In respect of AGFOL, individuals who perform one or more “controlled functions” such as significant influence functions (which includes all board members and other senior managers) or the customer function within authorized firms must be approved by the FCA to carry out that function. Individuals performing these functions are currently “Approved Persons” for the purpose of Part V of FSMA and staff performing these specified “controlled functions” within an authorized firm must be approved by the FCA.

From December 9, 2019, the Senior Managers and Certification Regime will be extended to almost all financial services firms and this will replace the current "Approved Persons" regime.
Change of Control
Under FSMA, when a person decides to acquire or increase “control” of a U.K. authorized firm (including an insurance company) they must give the PRA notice in writing before making the acquisition. The PRA has up to 60 working days (without including any period of interruption) in which to assess a change of control case. Any person (a company or individual) that directly or indirectly acquires 10% or 20% (depending on the type of firm, the “Control Percentage Threshold”) or more of the shares, or is entitled to exercise or control the exercise of the Control Percentage Threshold or more of the voting power, in a U.K. authorized firm or its parent undertaking is considered to “acquire control” of the authorized firm. Broadly speaking, the 10% threshold applies to banks, insurers and reinsurers (but not brokers) and MiFID investment firms, and the 20% threshold to insurance brokers and certain other firms that are non-directive firms.
Intervention and Enforcement
The PRA has extensive powers to intervene in the affairs of an authorized firm, culminating in the sanction of the suspension of authorization to carry on a regulated activity. The PRA can also vary or cancel a firm's permissions under its own initiative if it considers that the firm is failing, or is likely to fail, to satisfy the Threshold Conditions. FSMA gives the PRA significant investigation and enforcement powers. It also gives the PRA a rule-making power, under which it makes the various rules that constitute its Handbook of Rules.Rulebook.
The PRA also has the power to prosecute criminal offenses arising under FSMA. The FCA has the power to prosecute offenses under FSMA and to prosecute insider dealing under Part V of the Criminal Justice Act of 1993, and breaches by authorized firms of money laundering and terrorist financing regulations.
“Passporting”
EU directives currently allow AGE AGUK, AGLN and AGFOL to conduct business in EU states other than the U.K. where they are authorized by the PRA or FCA under a single market directive. This right extends to the EEA. A firm taking advantage of a right under a single market directive to conduct business in another EEA state can rely on its "home state" authorization. This ability to operate in other jurisdictions of the EEA on the basis of home state authorization and supervision is sometimes referred to as “passporting.” Each of AGE AGUK, AGLN and AGFOL is passported to conduct business in EEA states other than the U.K. Passporting is not applicable to firms not authorized in the EEA, such as AGM and AGC. Accordingly, the co-insurance model described above cannot be “passported” throughout the EEA. Instead, it is a question of local law in each EEA member state as to whether AGM's or AGC’s participation in a co-insurance structure, protecting insureds or risks located in that jurisdiction, would amount to the conduct of insurance business in that jurisdiction. (See also “U.K. referendum vote to leave the EU” below.)
Fees and Levies
Each of AGE AGUK, AGLN and AGFOL is subject to regulatory fees and levies based on its gross premium income and gross technical liabilities. These fees are collected by the FCA (though they relate to regulation by both the PRA and the FCA). The PRA also requires authorized firms, including authorized insurers, to participate in an investors' protection fund, known as the Financial Services Compensation Scheme. The Financial Services Compensation Scheme was established to compensate consumers of financial services firms, including the buyers of insurance, against failures in the financial services industry. Eligible claimants (identified in the Compensation SourcebookPolicyholder Protection section of the PRA Handbook)Rulebook) may be compensated by the Financial Services Compensation Scheme when an authorized insurer is unable, or likely to be unable, to satisfy policyholder claims. General insurance in class 14 (credit) is not protected by the Financial Services Compensation Scheme, nor is reinsurance in any class; however, other direct insurance classes written by AGUK and AGE are covered (namely, classes 15 (suretyship) and 16 (miscellaneous financial loss)).

Material Contracts

AGE’s New York affiliate, AGM currently provides support to AGE through a quota share and excess of loss reinsurance agreement (the AGM Reinsurance Agreement) and a net worth maintenance agreement (the AGE Net Worth Agreement). For transactions closed prior to 2011, AGE typically guaranteed all

The versions of such agreements currently in force became effective on November 7, 2018 upon completion of the guaranteed obligations directly andCombination. These new agreements clarified the application of the prior agreements to AGE upon the Combination. They also incorporated changes to certain terms of the prior agreements requested by the PRA during its review of the Combination, including a change to the amount of collateral that AGM reinsured underis obligated to post to secure its reinsurance of AGE. Except for such changes, the new agreements do not materially alter the terms or coverage of the prior agreements.
The AGM Reinsurance Agreement - Quota Share Reinsurance: Under the quota share cover of the prior AGM Reinsurance Agreement AGM reinsured between approximately 92%95% - 99% of AGE's retention of each AGE financial guaranty insurance policy after cessions to other reinsurers. In 2011,Such range of proportionate reinsurance by AGM was the result of a formula in the prior AGM Reinsurance Agreement that fixed AGM’s reinsurance of AGE policies issued during a particular calendar year based upon the respective prior year-end capitalization of AGE and AGM.

The AGE policies reinsured pursuant to the prior AGM Reinsurance Agreement were limited to ones issued in 2011 and prior years because:

(a) AGE and AGM in 2011 implemented a co-guarantee structure pursuant to which (i) AGE, rather than guaranteeing directly all of the obligations issued in a particular transaction, directly guarantees, ainstead, only the portion of the guaranteed obligations in an amount equal to what would have been AGE's pro rata retention percentage under the quota share cover of the prior AGM Reinsurance Agreement, (ii) AGM directly guarantees the balance of the guaranteed obligations, and (iii) AGM also provides a

second-to-pay guarantee for AGE's portion of the guaranteed obligations. AGM's ability to provide such direct guaranties outsideobligations; and

(b) the prior AGM Reinsurance Agreement excluded AGE’s insured portion of the U.K. is uncertain. See "Passporting" above.co-guaranteed obligations from reinsurance by AGM, and all AGE business since 2011 has consisted of transactions insured pursuant to such co-guarantee structure.

The new AGM Reinsurance Agreement maintains in place AGM’s proportionate reinsurance of all AGE policies covered under the prior AGM Reinsurance Agreement. The new agreement provides, however, that to the extent AGE issues a future qualifying policy without utilizing the co-guarantee structure described above, AGM will reinsure a fixed 85% share of AGE’s gross liabilities under such policy, rather than a percentage share based on AGE’s and AGM’s respective prior year-end capitalization. Similarly, the percentages of a future transaction’s obligations that AGE and AGM co-guarantee will be split 15% by AGE and 85% by AGM, so that AGM”s co-guaranteed portion continues to mirror the percentage of quota share reinsurance AGM otherwise would provide for the transaction under the new AGM Reinsurance Agreement.

The AGM Reinsurance Agreement - Excess of Loss Reinsurance: Under the excess of loss cover of the prior AGM Reinsurance Agreement, AGM payswas obligated to pay AGE quarterly the amount, if any, by which (i) the sum of (a) AGE’s incurred losses calculated in accordance with U.K. GAAP as reported by AGE in its financial returns filed with the PRA and (b) AGE’s paid losses and loss adjustment expenses (LAE),LAE, in both cases net of all other performing reinsurance, including the reinsurance provided by the Company under the quota share cover of the AGM Reinsurance Agreement, exceedsexceeded (ii) an amount equal to (a) AGE’s capital resources under U.K. law minus (b) 110% of the greatest of the amounts as maymight be required by the PRA as a condition for AGE to maintain its authorization to carry on a financial guarantee business in the U.K. The new AGM Reinsurance Agreement permitsprovides this same form of excess of loss reinsurance; it simply clarifies that such reinsurance covers the legacy portfolios transferred to AGE by AGUK, AGLN and CIFGE in addition to the legacy AGE policies reinsured under the prior AGM Reinsurance Agreement.

Other Provisions of the AGM Reinsurance Agreement: Under the new AGM Reinsurance Agreement, AGM’s required collateral is 102% of the sum of AGM’s assumed share of the following for all AGE policies for which AGM provides proportionate reinsurance: (a) AGE’s unearned premium reserve (net of AGE’s reinsurance premium payable to AGM); (b) AGE’s provisions for unpaid losses and allocated loss adjustment expenses (net of any salvage recoverable), and (c) any unexpired risk provisions of AGE, in each case (a) - (c) as calculated by AGE in accordance with U.K. GAAP. This new, post-Combination collateral measure is in contrast to (i) AGM’s collateral measure prevailing from December 2014 through 2015, which was based, in part, upon the losses expected to be borne by AGM (and two other affiliated reinsurers of AGE, AG Re and AGRO) at the 99.5% confidence interval under the PRA’s FG Benchmark Model; and (ii) AGM’s collateral measure prevailing from 2016 up to the time of the Combination, which was based on the same losses calculated under AGE’s internal capital

requirement model instead of the FG Benchmark Model. As a result of this new collateral measure, AGM’s total collateral required for AGE increased by approximately $52 million upon the Combination. AGM funded such increase promptly following the Combination.

The quota share and excess loss covers under the prior AGM Reinsurance Agreement excluded transactions guaranteed by AGE on or after July 1, 2009 that were not municipal, utility, project finance or infrastructure risks or similar types of risks. The new AGM Reinsurance Agreement retains the same exclusion. The old AGM Reinsurance Agreement also permitted AGE to terminate the Reinsurance Agreementagreement upon the following events: a downgrade of AGM’s ratings by Moody’s below Aa3 or by S&P below AA- if AGM fails to restore its rating(s) to the required level within a prescribed period of time; AGM's insolvency; failure by AGM to maintain the minimum capital required by its domiciliary jurisdiction; or AGM filing a petition in bankruptcy, going into liquidation or rehabilitation or having a receiver appointed. The new AGM Reinsurance Agreement preserves these same termination rights by AGE, and also adds an additional termination right enabling AGE to terminate the agreement should AGM fail to maintain its required collateral.

The quota share and excess loss covers each exclude transactions guaranteed by AGE on or after July 1, 2009 that are not municipal, utility, project finance or infrastructure risks or similar types of risks.

The Reinsurance Agreement also contemplates the establishment of collateral by AGM to support AGM’s reinsurance obligations to AGE.  In December 2014, to satisfy the PRA’s collateral requirements, AGM and AGE entered into a trust agreement pursuant to which AGM established and deposited assets into a reinsurance trust account for the benefit of AGE. AGM’s collateral requirement was measured during 2015, as of the end of each calendar quarter, by (i) using the PRA’s FG Benchmark Model to calculate at the 99.5% confidence interval the losses expected to be borne collectively by AGE’s three affiliated reinsurers, AGM, AG Re and AGRO; (ii) deducting from such calculation AGE’s capital resources under such model; and (iii) requiring AGM, AG Re and AGRO collectively to maintain collateral equal to fifty percent (50%) of such difference, i.e., the excess of AGM’s, AG Re’s and AGRO’s assumed modeled losses over AGE’s capital resources.  As of January 1, 2016, the PRA agreed to allow AGM’s collateral requirement to be determined using AGE’s internal capital requirement model instead of the FG Benchmark Model under the same formula described above. This change in the calculation of AGM's required collateral was reflected in an amendmentNet Worth Agreement: Pursuant to the Reinsurance Agreement approved by the NYDFS and made effective in April 2016.

Pursuant to theprior AGE Net Worth Agreement, AGM iswas obligated to cause AGE to maintain capital resources equal to 110% of the greatest of the amounts as may be required by the PRA as a condition for AGE to maintain its authorization to carry on a financial guarantee business in the U.K., provided that AGM's contributions (a) dodid not exceed 35% of AGM's policyholders' surplus on an accumulated basis as determined by the laws of the State of New York, and (b) arewere in compliance with Section 1505 of the New York Insurance Law. AGM’s obligation remains the same under the new AGE Net Worth Agreement, which simply clarifies that it applies to AGE’s expanded insurance and investment portfolios resulting from the Combination. AGM has never been required to make any contributionsa contribution to AGE's capital under any version of the AGE Net Worth Agreement - either the current agreement or theany prior net worth maintenance agreement. With the approval of the NYDFS, AGE and AGM amended theagreements. The new AGE Net Worth Agreement effective in April 2016also permits AGE to provide for useterminate such agreement without also triggering an automatic termination of the internal capital requirement model.AGM Reinsurance Agreement (as would have occurred under the prior AGE Net Worth Agreement).

The NYDFS approved each of the changes described above to the AGM Reinsurance Agreement and AGE Net Worth Maintenance Agreement.

AGUK’s parent company,AGC’s Support Agreements in Respect of AGUK: Prior to the Combination, the Company's affiliate, AGC, currently providesprovided support to AGUK through a further amendedFurther Amended and restatedRestated quota share reinsurance agreement (the AGC Quota Share Agreement), a further amendedFurther Amended and restatedRestated excess of loss reinsurance agreement (the AGC XOL Agreement), and a further amendedFurther Amended and restatedRestated net worth maintenance agreement (the "AGUKAGUK Net Worth Agreement")Agreement). Pursuant toThe latter two agreements were terminated effective upon the Combination because AGUK’s legacy policies became part of AGE’s portfolio upon the Combination and, therefore, are now covered by the excess of loss portion of the new AGM Reinsurance Agreement and the new AGE Net Worth Maintenance Agreement, as described above. The AGC Quota Share Agreement, AGUK cedespursuant to which AGC provided 90% quota share reinsurance of its financial guaranty insurance and reinsurance exposure to AGC. Pursuant toAGUK’s legacy policies, was also terminated upon the XOL Agreement, AGC indemnifies AGUK for 100% of losses (net of theCombination, but it was replaced with a new quota share reinsurance agreement discussed above) incurred by AGUK in excess of an amount equal to (a) AGUK’s capital resources minus (b) 110%between AGE and AGC (the New AGC Reinsurance Agreement). This new agreement preserves AGC’s 90% quota share reinsurance of the greatestlegacy AGUK policies that are now part of AGE’s portfolio, but it has no application to new business written by AGE following the amountsCombination. The new AGC Reinsurance Agreement also imposes a new collateral requirement on AGC that is the same as may be required by the PRA as a condition for AGUK maintaining its authorization to carry on a financial guarantee business in the U.K. Pursuant to the AGUK Net Worth Agreement, if AGUK's net worth falls below 110% of the minimum level of capital required by the PRA, AGC must invest additional funds in order to bring the capital of AGUK back into compliance with the required amount.

In 2016, AGC and AGUK reached an agreement with the PRA that, in order for AGC to secure its outstanding reinsurance of AGUKAGM’s collateral requirement under the Quota Sharenew AGM Reinsurance Agreement, and XOL Agreement,as described above, except that AGC shallcontinues also to post as collateral its share of AGUK-guaranteedtwo AGE-guaranteed (formerly, pre-Combination, AGUK-guaranteed) triple-X insurance bonds that have been purchased by AGC for loss mitigation and an additional amount to be determined by (i) using AGUK’s internal capital requirement model to calculate at(as AGC had similarly done under the 99.5% confidence intervalprior AGC Quota Share Agreement).

The MIA approved the losses expected to be borne by AGC for the exposures it has assumed from AGUK that do not have loss reserves (non-reserve exposures); (ii) adding the amount of loss reserves ceded by AGUK to AGC under U.K. GAAP; (iii) subtracting from such sum AGUK’s capital resources under its internal capital requirement model (the result of clauses (i) through (iii) being referred to as the resulting amount); and then (iv) reducing the resulting amount by 50%termination of the portion ofprior AGC XOL Agreement, AGUK Net Worth Agreement and the resulting amount that was contributed by the non-reserve exposures. Accordingly, AGC and AGUK entered into a trust agreement pursuant to which AGC established a reinsurance trust account for the benefit of AGUK and deposits therein sufficient assets to satisfy the above-

described collateral requirement agreed with the PRA. This new collateral requirement is reflected in the Quota Share Agreement and XOL Agreement, whichthe replacement of the latter with the new AGC Reinsurance Agreement.

AGC’s Letter of Support in Respect of CIFGE: AGC was a party to a letter of support dated December 6, 2001 issued to CIFGE.  Pursuant to such letter of support, AGC agreed to maintain CIFGE’s statutory capital and surplus to policyholders under French law and regulation in an amount not less than €20 million for so long as CIFGE carried on business. No capital contributions were approvedmade to CIFGE by AGC pursuant to this letter of support from the time AGC succeeded CIFGNA as the parent of CIFGE in July 2016 up to the Combination on November 7, 2018. The letter of support was terminated, with the MIA’s approval, effective upon the Combination since the legacy CIFGE policies are now part of AGE and, therefore, are covered by the MIAexcess of loss portion of the new AGM Reinsurance Agreement and made effective in July 2016.the new AGE Net Worth Agreement.

U.K. referendum vote to leave the European Union

On June 23, 2016, the U.K. voted in a national referendum to withdraw from the EU. The result of the referendum does not legally oblige the U.K. to exit the European UnionEU (a so-called Brexit). However, on March 29, 2017 the U.K. government has indicated that it intends to formally serve served

notice to the European Council of its desire to withdraw in accordance with Article 50 of the Treaty on European Union (Article 50) by the end of March 2017..

Article 50 envisages a negotiation period leading to an exit on a mutually agreed date. However, in the absence of such mutual agreement, the default date for exit is two years after the member state serves the Article 50 notice. EU treaties will therefore cease to apply to the U.K. on the earlier of (i) the entry into force of any withdrawal agreement or (ii) two years after the giving of notice (unless the U.K. and all remaining Member States unanimously agree to extend the negotiation period), currently contemplated.

As part of the negotiations, the U.K. is seeking a transition period during which it will have ceased to be a member state of the EU, but will continue to have rights and obligations under EU law, other than the right to participate formally in the EU decision making process. The EU published a paper setting out its terms for a transition period on January 29, 2018, one of which was that the transition period should not last beyond December 31, 2020. The transition period will be dependent upon the U.K. and EU agreeing to the terms of a withdrawal agreement, which has been largely completed, but has not yet been approved by the U.K. Parliament.

Failing the entry into effect of the withdrawal agreement or an agreed extension to the planned U.K. departure date, the U.K. will leave the EU on March 2019.29, 2019 with no agreement on the terms of its departure (a No-Deal Brexit), leaving considerable uncertainty as to the ongoing relationship and a likely negative impact on all parties. Given the lack of clarity on the ultimate post-Brexit relationship between the U.K. and the EU, the Company cannot fully determine what, if any, impact Brexit may have on its operations, both inside and outside the U.K.

A further question arising from Brexit is whether U.K. authorized financial services firms such as AGE will continue to enjoy passporting rights to the other 27 EEA states after Brexit. This question will be particularly acute in the event of a No-Deal Brexit, because the loss of passporting could occur as early as March 29, 2019, rather than December 31, 2020, the end of the transition period under the withdrawal agreement. As a consequence, Assured Guaranty is establishing a new subsidiary in Paris, France, in order to continue with the ability to write new business, and to service existing business, in those other EEA states. That new subsidiary is unlikely to be fully licensed prior to a No-Deal Brexit, should that occur. While the Company believes that, in the event of a No-Deal Brexit or in the absence of applicable transition rules, those other EEA states outside the U.K. will permit the Company to continue to service existing business in their states, there can be no assurance that this will occur, nor can the Company fully determine the impact on its business and operations if it does not occur.

Until the U.K. formally withdraws fromleaves the EU, EU legislation will remain in force and the role of EU institutions will be unchanged. On withdrawal of the U.K. from the EU, in the absence of any agreement to the contrary, all treaty obligations would lapse, directives, directly effective decisions and regulations (as well as rulings of the Court of Justice of the EU) would cease to apply and the competencies of EU institutions would fall away. The EU's paper on the transition arrangements published on January 29, 2018 envisages EU legislation continuing to apply to the U.K. throughout the transition period.

The U.K. Government has announced its intentionproposed legislation to bring all aspects of European law to the extent possible into U.K. law prior to the U.K. exiting the EU. It seems most likely, given the relatively short timescalestimeframe available, that initially Solvency II will be brought into U.K. law in substantially its current form. Retaining Solvency II in substantially its current form would also make it easier for the U.K. to obtain a ruling of “equivalence” from the European Commission under Solvency II, which would accord insurers certain advantages when it comes to the Solvency II rules on reinsurance, the calculation of group capital and group supervision.

The U.K. Government could take time to review whether there might be any changes which are desired on a national level. The Treasury Select Committee of the House of Commons is currently reviewinghas conducted a review of Solvency II and has indicated that it will do so against the backdrop of Brexit, taking into account certain features which are regarded as unsuitable by the U.K. industry. The results of the Treasury Select Committee’s work have been responded to by the PRA and may feed in to future discussions about potential changes to the Solvency II regime.U.K. insurance regulation.

Any changes to Solvency IIU.K. insurance regulation following Brexit could reduce the chances of the U.K. obtaining (or subsequently preserving) a ruling of equivalence.

A further question arisingSee the Risk Factor captioned "Brexit may adversely impact exposures insured by the Company and may also impact the Company through currency exchange rates" under Risks Related to the Financial, Credit and Financial Guaranty Markets and Risk Factor captioned "Changes in applicable laws and regulations resulting from Brexit is whether U.K. authorised financial services firms such as AGEmay adversely effect the Company" under Risks Related to GAAP and AGUK will continue to enjoy passporting rights to the other 27 EEA states after Brexit. In the event that passporting rights are not retained, Assured Guaranty is assessing a number of optionsApplicable Law, in order to continue with the ability to write new business, and to run off existing business, in those EEA states.Item 1A, Risk Factors.

France

In connection with the CIFG Acquisition in July 2016, the Company acquired a French insurer called CIFG Europe S.A. which is now in run off. CIFGNA had reinsured all of CIFGE’s outstanding financial guaranty business and also had issued a “second-to-pay policy” pursuant to which CIFGNA guaranteed the full and complete payment of any shortfall in amounts due from CIFGE on its insured portfolio. AGC assumed these obligations as part of the CIFGNA merger with and into AGC. CIFGE remains a separate subsidiary in run off, now owned by AGC.  Prior to the CIFG Acquisition, CIFGE had prepared a run off plan which was approved by its French regulator, theAutorité de contrôle prudentiel et de résolution (ACPR).  CIFGE has been in run off for more than two years, and therefore has surrendered its licence under French law to write new insurance business.  The withdrawal of the licence has no practical impact on the level of supervision exercised by the ACPR over CIFGE as an insurer.


Tax Matters

United States Tax Reform

Recent tax reform commonly referred to as the 2017 Tax Cuts and Jobs Act (Tax Act) was passed by the U.S. Congress and was signed into law on December 22, 2017. The Tax Act lowered the corporate U.S. tax rate to 21%, eliminated the alternative minimum tax, limited the deductibility of interest expense and requires a one-time tax on a deemed repatriation of untaxed earnings of non-U.S. subsidiaries. In the context of the taxation of U.S. property/casualty insurance companies such as the Company, the Tax Act also modifies the loss reserve discounting rules and the proration rules that apply to reduce reserve deductions to reflect the lower corporate income tax rate. In addition, the Tax Act included certain provisions intended to eliminate certain perceived tax advantages of companies (including insurance companies) that have legal domiciles outside the United States but have certain U.S. connections and United States persons investing in such companies. For example, the Tax Act includes a base erosion anti-avoidance tax (BEAT) that could make affiliate reinsurance between United States and non-U.S. members of the Company's group economically unfeasible. In addition, the Tax Act introduced a current tax on global intangible low taxed income that may result in an increase in U.S. corporate income tax imposed on the Company's U.S. group members with respect to earnings of their non-U.S. subsidiaries. As discussed in more detail below, the Tax Act also revised the rules applicable to passive foreign investment companies (PFICs) and controlled foreign corporations (CFCs). Although the Company is currently unable to predict the ultimate impact of the Tax Act on its business, shareholders and results of operations, it is possible that the Tax Act may increase the U.S. federal income tax liability of U.S. members of the group that cede risk to non-U.S. group members and may affect the timing and amount of U.S. federal income taxes imposed on certain U.S. shareholders. Further, it is possible that other legislation could be introduced and enacted by the current Congress or future Congresses that could have an adverse impact on the Company. Additionally, tax laws and interpretations regarding whether a company is engaged in a U.S. trade or business or whether a company is a CFC or a PFIC or has related person insurance income (RPII) are subject to change, possibly on a retroactive basis. Currently there are only proposed regulations regarding the application of the PFIC rules to an insurance company. Additionally, the regulations regarding RPII have been in proposed form since 1991. New regulations or pronouncements interpreting or clarifying such rules may be forthcoming. The Company cannot be certain if, when or in what form such regulations or pronouncements may be provided and whether such guidance will have a retroactive effect. See Part II, Item 8, Financial Statements and Supplementary Data, Note 1, Business and Basis of Presentation and Note 12, Income Taxes.

Taxation of AGL and Subsidiaries

Bermuda

Under current Bermuda law, there is no Bermuda income, corporate or profits tax or withholding tax, capital gains tax or capital transfer tax payable by AGL or its Bermuda subsidiaries.Subsidiaries. AGL, AG Re and AGRO have each obtained from the Minister of Finance under the Exempted Undertakings Tax Protection Act 1966, as amended, an assurance that, in the event that Bermuda enacts legislation imposing tax computed on profits, income, any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance, then the imposition of any such tax shall not be applicable to AGL, AG Re or AGRO or to any of their operations or their shares, debentures or other obligations, until March 31, 2035. This assurance is subject to the provisoprovision that it is not to be construed so as to prevent the application of any tax or duty to such persons as are ordinarily resident in Bermuda, or to prevent the application of any tax payable in accordance with the provisions of the Land Tax Act 1967 or otherwise payable in relation to any land leased to AGL, AG Re or AGRO. AGL, AG Re and AGRO each pays annual Bermuda government fees, and AG Re and AGRO pay annual insurance license fees. In addition, all entities employing individuals in Bermuda are required to pay a payroll tax and there are other sundry taxes payable, directly or indirectly, to the Bermuda government.

AGL has conducted and intends to continue to conduct substantially all of its operations outside the U.S. and to limit the U.S. contacts of AGL and its foreignnon-U.S. subsidiaries (except AGRO, and AGE, which have elected to be taxed as a U.S. corporations)corporation) so that they should not be engaged in a trade or business in the U.S. A foreignnon-U.S. corporation, such as AG Re, that is deemed to be engaged in a trade or business in the United States would be subject to U.S. income tax at regular corporate rates, as well as the branch profits tax, on its income which is treated as effectively connected with the conduct of that trade or business, unless the corporation is entitled to relief under the permanent establishment provision of an applicable tax treaty, as discussed below. Such income tax, if imposed, would be based on effectively connected income computed in a manner generally analogous to that applied to the income of a U.S. corporation, except that a foreignnon-U.S. corporation would generally be entitled to deductions and credits only if it timely files a U.S. federal income tax return. AGL, AG Re and certain of the other foreignnon-U.S. subsidiaries have and will continue to file protective U.S. federal income tax returns on a timely basis in order to preserve the right to claim

income tax deductions and credits if it is ever determined that they are subject to U.S. federal income tax. The highest marginal federal income tax rates currently are 35%21% for a corporation's effectively connected income and 30% for the "branch profits" tax.

Under the income tax treaty between Bermuda and the U.S. (the Bermuda Treaty), a Bermuda insurance company would not be subject to U.S. income tax on income found to be effectively connected with a U.S. trade or business unless that trade or business is conducted through a permanent establishment in the U.S. AG Re currently intends to conduct its activities so that it does not have a permanent establishment in the U.S.

An insurance enterprise resident in Bermuda generally will be entitled to the benefits of the Bermuda Treaty if (i) more than 50% of its shares are owned beneficially, directly or indirectly, by individual residents of the U.S. or Bermuda or U.S. citizens and (ii) its income is not used in substantial part, directly or indirectly, to make disproportionate distributions to, or to meet certain liabilities of, persons who are neither residents of either the U.S. or Bermuda nor U.S. citizens.

ForeignNon-U.S. insurance companies carrying on an insurance business within the U.S. have a certain minimum amount of effectively connected net investment income, determined in accordance with a formula that depends, in part, on the amount of U.S. risk insured or reinsured by such companies. If AG Re or another of the Company's Bermuda subsidiariesSubsidiaries is considered to be engaged in the conduct of an insurance business in the U.S. and is not entitled to the benefits of the Bermuda Treaty in general (because it fails to satisfy one of the limitations on treaty benefits discussed above), the Internal Revenue Code of 1986, as amended (the Code), could subject a significant portion of AG Re's or another of the Company's Bermuda subsidiary's investment income to U.S. income tax.

AGL, as a U.K. tax resident, would not be subject to U.S. income tax on any income found to be effectively connected with a U.S. trade or business under the income tax treaty between the U.S. and the U.K. (the U.K. Treaty), unless that trade or business is conducted through a permanent establishment in the United States. AGL intends to conduct its activities so that it does not have a permanent establishment in the United States. 


ForeignNon-U.S. corporations not engaged in a trade or business in the U.S., and those that are engaged in a U.S. trade or business with respect to their non-effectively connected income are nonetheless subject to U.S. withholding tax on certain "fixed or determinable annual or periodic gains, profits and income" derived from sources within the U.S. (such as dividends and certain interest on investments), subject to exemption under the Code or reduction by applicable treaties. The standard non-treaty rate of U.S. withholding tax is currently 30%. The Bermuda Treaty does not reduce the U.S. withholding rate on U.S.-sourced investment income. The U.K. Treaty reduces or eliminates U.S. withholding tax on certain U.S. sourced investment income, including dividends from U.S. companies to U.K. resident persons entitled to the benefit of the U.K. Treaty.
    
The U.S. also imposes an excise tax on insurance and reinsurance premiums paid to foreignnon-U.S. insurers with respect to risk of a U.S. person located wholly or partly within the U.S. or risks of a foreign person engaged in a trade or business in the U.S. which are located within the U.S. The rates of tax applicable to premiums paid are 4% for direct casualty insurance premiums and 1% for reinsurance premiums.

AGRO and AGE havehas elected to be treated as a U.S. corporationscorporation for all U.S. federal tax purposes and, as such, each of AGRO, and AGE, together with AGL's U.S. subsidiaries, is subject to taxation in the U.S. at regular corporate rates.

If AGRO were to pay dividends to its U.S. holding company parent and that U.S. holding company were to pay dividends to its Bermudian parent AG Re, such dividends would be subject to U.S. withholding tax at a rate of 30%.

United Kingdom

In November 2013, AGL became tax resident in the U.K. AGL remains a Bermuda-based company and its administrative and head office functions continue to be carried on in Bermuda. The AGL common shares have not changed and continue to be listed on the New York Stock Exchange (NYSE).

As a company that is not incorporated in the U.K., AGL will be considered tax resident in the U.K. only if it is “centrally managed and controlled” in the U.K. Central management and control constitutes the highest level of control of a company’s affairs. Effective November 6, 2013, the AGL Board intends to manage the affairs of AGL in such a way as to maintain its status as a company that is tax resident in the U.K.

As a U.K. tax resident company, AGL is subject to the tax rules applicable to companies resident in the U.K., including the benefits afforded by the U.K.’s tax treaties.

As a U.K. tax resident, AGL is required to file a corporation tax return with Her Majesty’s Revenue & Customs (HMRC). AGL will be subject to U.K. corporation tax in respect of its worldwide profits (both income and capital gains), subject to any applicable exemptions. The main rate of corporation tax is currently 20%. It19% and will be further reduced to 19% with effect from April 1, 2017 and 17% with effect from April 1, 2020. AGL has also registered in the U.K. to report its value added tax (VAT) liability. The current rate of VAT is 20%.

The dividends AGL receives from its direct subsidiaries should be exempt from U.K. corporation tax due to the exemption in section 931D of the U.K. Corporation Tax Act 2009. In addition, any dividends paid by AGL to its shareholders should not be subject to any withholding tax in the U.K. The non-U.K. resident subsidiaries intend to operate in such a manner that their profits are outside the scope of the charge under the "controlled foreign companies" (CFC) regime. Accordingly, Assured Guaranty does not expect any profits of non-U.K. resident members of the group to be attributed to AGL and taxed in the U.K. under the CFC regime and has obtained clearance from HMRC confirming this on the basis of current facts and intentions.

Taxation of Shareholders

Bermuda Taxation

Currently, there is no Bermuda capital gains tax, or withholding or other tax payable on principal, interest or dividends paid to the holders of the AGL common shares.

United States Taxation

This discussion is based upon the Code, the regulations promulgated thereunder and any relevant administrative rulings or pronouncements or judicial decisions, all as in effect on the date hereof and as currently interpreted, and does not

take into account possible changes in such tax laws or interpretations thereof, which may apply retroactively. This discussion does not include any description of the tax laws of any state or local governments within the U.S. or any foreign government.

The following summary sets forth the material U.S. federal income tax considerations related to the purchase, ownership and disposition of AGL's shares. Unless otherwise stated, this summary deals only with holders that are U.S. Persons (as defined below) who purchase and hold their shares and who hold their shares as capital assets within the meaning of section 1221 of the Code. The following discussion is only a discussion of the material U.S. federal income tax matters as described herein and does not purport to address all of the U.S. federal income tax consequences that may be relevant to a particular shareholder in light of such shareholder's specific circumstances. For example, special rules apply to certain shareholders, such as partnerships, insurance companies, regulated investment companies, real estate investment trusts, dealers or traders in securities, tax exempt organizations, expatriates, persons that do not hold their securities in the U.S. dollar, persons who are considered with respect to AGL or any of its foreignnon-U.S. subsidiaries as "United States shareholders" for purposes of the controlled foreign corporation (CFC)CFC rules of the Code (generally, a U.S. Person, as defined below, who owns or is deemed to own 10% or more of the total combined voting power or value of all classes of AGL or the stock of any of AGL's foreignnon-U.S. subsidiaries entitled to vote (i.e., 10% U.S. Shareholders)), or persons who hold the common shares as part of a hedging or conversion transaction or as part of a short-sale or straddle. Any such shareholder should consult their tax advisor.

If a partnership holds AGL's shares, the tax treatment of the partners will generally depend on the status of the partner and the activities of the partnership. Partners of a partnership owning AGL's shares should consult their tax advisers.

For purposes of this discussion, the term "U.S. Person" means: (i) a citizen or resident of the U.S., (ii) a partnership or corporation, created or organized in or under the laws of the U.S., or organized under any political subdivision thereof, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source, (iv) a trust if either (x) a court within the U.S. is able to exercise primary supervision over the administration of such trust and one or more U.S. Persons have the authority to control all substantial decisions of such trust or (y) the trust has a valid election in effect to be treated as a U.S. Person for U.S. federal income tax purposes or (v) any other person or entity that is treated for U.S. federal income tax purposes as if it were one of the foregoing.

Taxation of Distributions.    Subject to the discussions below relating to the potential application of the CFC, related person insurance income (RPII)RPII and passive foreign investment company (PFIC)PFIC rules, cash distributions, if any, made with respect to AGL's shares will constitute dividends for U.S. federal income tax purposes to the extent paid out of current or accumulated earnings and profits of AGL (as computed using U.S. tax principles). Dividends paid by AGL to corporate shareholders will not be eligible for the dividends received deduction. To the extent such distributions exceed AGL's earnings and profits, they will be treated first as a return of the shareholder's basis in the common shares to the extent thereof, and then as gain from the sale of a capital asset.


AGL believes dividends paid by AGL on its common shares to non-corporate holders will be eligible for reduced rates of tax at the rates applicable to long-term capital gains as "qualified dividend income," provided that AGL is not a PFIC and certain other requirements, including stock holding period requirements, are satisfied.

Classification of AGL or its ForeignNon-U.S. Subsidiaries as a Controlled Foreign Corporation.CFC.   Each 10% U.S. Shareholder (as defined below) of a foreignnon-U.S. corporation that is a CFC for an uninterrupted period of 30 days or moreat any time during a taxable year and whothat owns, shares in the foreign corporation, directly or indirectly through foreignnon-U.S. entities, shares in the non-U.S. corporation on the last day of the foreignnon-U.S. corporation's taxable year inon which it is a CFC, must include in its gross income, for U.S. federal income tax purposes, its pro rata share of the CFC's "subpart F income," even if the subpart F income is not distributed. "Subpart F income" of a foreignnon-U.S. insurance corporation typically includes foreignnon-U.S. personal holding company income (such as interest, dividends and other types of passive income), as well as insurance and reinsurance income (including underwriting and investment income). A foreignnon-U.S. corporation is considered a CFC if 10% U.S. Shareholders own (directly, indirectly through foreignnon-U.S. entities or by attribution by application of the constructive ownership rules of section 958(b) of the Code (i.e., constructively)) more than 50% of the total combined voting power of all classes of voting stock of such foreignnon-U.S. corporation, or more than 50% of the total value of all stock of such corporation on any day during the taxable year of such corporation. For purposes of taking into account insurance income, a CFC also includes a foreignnon-U.S. insurance company in which more than 25% of the total combined voting power of all classes of stock (or more than 25% of the total value of the stock) is owned by 10% U.S. Shareholders, on any day during the taxable year of such corporation. A "10% U.S. Shareholder" is a U.S. Person who owns (directly, indirectly through foreignnon-U.S. entities or constructively) at least 10% of the total combined voting power or value of all classes of stock entitled to vote of the foreignnon-U.S. corporation. The Tax Act expanded the definition of 10% U.S. Shareholder to include ownership by value (rather than just vote), so provisions in the Company's organizational documents that cut back voting power to potentially avoid 10% U.S. Shareholder status will no longer mitigate the risk of 10% U.S. Shareholder status. AGL believes that because of the dispersion of AGL's share ownership, provisions in AGL's organizational documents that limit voting power (these provisions are described in "Description of Share Capital") and other factors, no U.S. Person who owns shares of AGL directly or indirectly through one or more foreignnon-U.S. entities should be treated as owning (directly, indirectly through foreignnon-U.S. entities, or constructively), 10% or more of the total voting power or value of all classes of shares of

AGL or any of its foreignnon-U.S. subsidiaries. It is possible, however, thatHowever, AGL’s shares may not be as widely dispersed as the Internal Revenue Service (IRS) could challengeCompany believes due to, for example, the effectivenessapplication of these provisionscertain ownership attribution rules, and no assurance may be given that a court could sustain suchU.S. Person who owns the Company's shares will not be characterized as a challenge.10% U.S. Shareholder. In addition, the direct and indirect subsidiaries of AGUSAssured Guaranty US Holdings Inc. (AGUS) are characterized as CFCs and any subpart F income generated will be included in the gross income of the applicable domestic subsidiaries in the AGL group.

The RPII CFC Provisions.    The following discussion generally is applicable only if the RPII of AG Re or any other foreignnon-U.S. insurance subsidiary that either (i) has not made an election under section 953(d) of the Code to be treated as a U.S. corporation for all U.S. federal tax purposes or are CFCs(ii) is not a CFC owned directly or indirectly by AGUS (each a "Foreign Insurance Subsidiary" or collectively, with AG Re, the "Foreign Insurance Subsidiaries") determined on a gross basis, is 20% or more of the Foreign Insurance Subsidiary's gross insurance income for the taxable year and the 20% Ownership Exception (as defined below) is not met. The following discussion generally would not apply for any taxable year in which the Foreign Insurance Subsidiary's gross RPII falls below the 20% threshold or the 20% Ownership Exception is met. Although the Company cannot be certain, it believes that each Foreign Insurance Subsidiary has been, in prior years of operations, and will be, for the foreseeable future, either below the 20% threshold or in compliance with the requirements of 20% Ownership Exception for each tax year.

RPII is any "insurance income" (as defined below) attributable to policies of insurance or reinsurance with respect to which the person (directly or indirectly) insured is a "RPII shareholder" (as defined below) or a "related person" (as defined below) to such RPII shareholder. In general, and subject to certain limitations, "insurance income" is income (including premium and investment income) attributable to the issuing of any insurance or reinsurance contract which would be taxed under the portions of the Code relating to insurance companies if the income were the income of a domestic insurance company. For purposes of inclusion of the RPII of a Foreign Insurance Subsidiary in the income of RPII shareholders, unless an exception applies, the term "RPII shareholder" means any U.S. Person who owns (directly or indirectly through foreignnon-U.S. entities) any amount of AGL's common shares. Generally, the term "related person" for this purpose means someone who controls or is controlled by the RPII shareholder or someone who is controlled by the same person or persons which control the RPII shareholder. Control is measured by either more than 50% in value or more than 50% in voting power of stock applying certain constructive ownership principles. A Foreignnon-U.S. Insurance Subsidiary will be treated as a CFC under the RPII provisions if RPII shareholders are treated as owning (directly, indirectly through foreignnon-U.S. entities or constructively) 25% or more of the shares of AGL by vote or value.

RPII Exceptions.    The special RPII rules do not apply if (i) at all times during the taxable year less than 20% of the voting power and less than 20% of the value of the stock of AGL (the 20% Ownership Exception) is owned (directly or indirectly through entities) by persons who are (directly or indirectly) insured under any policy of insurance or reinsurance issued by a Foreign Insurance Subsidiary or related persons to any such person, (ii) RPII, determined on a gross basis, is less

than 20% of a Foreign Insurance Subsidiary's gross insurance income for the taxable year (the 20% Gross Income Exception), (iii) a Foreign Insurance Subsidiary elects to be taxed on its RPII as if the RPII were effectively connected with the conduct of a U.S. trade or business, and to waive all treaty benefits with respect to RPII and meet certain other requirements or (iv) a Foreign Insurance Subsidiary elects to be treated as a U.S. corporation and waive all treaty benefits and meet certain other requirements. The Foreign Insurance Subsidiaries do not intend to make either of these elections. Where none of these exceptions applies, each U.S. Person owning or treated as owning any shares in AGL (and therefore, indirectly, in a Foreign Insurance Subsidiary) on the last day of AGL's taxable year will be required to include in its gross income for U.S. federal income tax purposes its share of the RPII for the portion of the taxable year during which a Foreign Insurance Subsidiary was a CFC under the RPII provisions, determined as if all such RPII were distributed proportionately only to such U.S. Persons at that date, but limited by each such U.S. Person's share of a Foreign Insurance Subsidiary's current-year earnings and profits as reduced by the U.S. Person's share, if any, of certain prior-year deficits in earnings and profits. The Foreign Insurance Subsidiaries intend to operate in a manner that is intended to ensure that each qualifies for either the 20% Gross Income Exception or 20% Ownership Exception.

Computation of RPII.    For any year in which a Foreign Insurance Subsidiary does not meet the 20% Ownership Exception or the 20% Gross Income Exception, AGL may also seek information from its shareholders as to whether beneficial owners of shares at the end of the year are U.S. Persons so that the RPII may be determined and apportioned among such persons; to the extent AGL is unable to determine whether a beneficial owner of shares is a U.S. Person, AGL may assume that such owner is not a U.S. Person, thereby increasing the per share RPII amount for all known RPII shareholders. The amount of RPII includable in the income of a RPII shareholder is based upon the net RPII income for the year after deducting related expenses such as losses, loss reserves and operating expenses. If a Foreign Insurance Subsidiary meets the 20% Ownership Exception or the 20% Gross Income Exception, RPII shareholders will not be required to include RPII in their taxable income.

Apportionment of RPII to U.S. Holders.    Every RPII shareholder who owns shares on the last day of any taxable year of AGL in which a Foreign Insurance Subsidiary does not meet the 20% Ownership Exception or the 20% Gross Income Exception should expect that for such year it will be required to include in gross income its share of a Foreign Insurance

Subsidiary's RPII for the portion of the taxable year during which the Foreign Insurance Subsidiary was a CFC under the RPII provisions, whether or not distributed, even though it may not have owned the shares throughout such period. A RPII shareholder who owns shares during such taxable year but not on the last day of the taxable year is not required to include in gross income any part of the Foreign Insurance Subsidiary's RPII.

Basis Adjustments.    An RPII shareholder's tax basis in its common shares will be increased by the amount of any RPII the shareholder includes in income. The RPII shareholder may exclude from income the amount of any distributions by AGL out of previously taxed RPII income. The RPII shareholder's tax basis in its common shares will be reduced by the amount of such distributions that are excluded from income.

Uncertainty as to Application of RPII.    The RPII provisions are complex and have never been interpreted by the courts or the Treasury Department in final regulations; regulations interpreting the RPII provisions of the Code exist only in proposed form. It is not certain whether these regulations will be adopted in their proposed form or what changes or clarifications might ultimately be made thereto or whether any such changes, as well as any interpretation or application of RPII by the IRS,Internal Revenue Service (IRS), the courts or otherwise, might have retroactive effect. These provisions include the grant of authority to the Treasury Department to prescribe "such regulations as may be necessary to carry out the purpose of this subsection including regulations preventing the avoidance of this subsection through cross insurance arrangements or otherwise." Accordingly, the meaning of the RPII provisions and the application thereof to the Foreign Insurance Subsidiaries is uncertain. In addition, the Company cannot be certain that the amount of RPII or the amounts of the RPII inclusions for any particular RPII shareholder, if any, will not be subject to adjustment based upon subsequent IRS examination. Any prospective investor which does business with a Foreign Insurance Subsidiary and is considering an investment in common shares should consult his tax advisor as to the effects of these uncertainties.

Information Reporting.    Under certain circumstances, U.S. Persons owning shares (directly, indirectly or constructively) in a foreignnon-U.S. corporation are required to file IRS Form 5471 with their U.S. federal income tax returns. Generally, information reporting on IRS Form 5471 is required by (i) a person who is treated as a RPII shareholder, (ii) a 10% U.S. Shareholder of a foreignnon-U.S. corporation that is a CFC for an uninterrupted period of 30 days or more during any tax year of the foreignnon-U.S. corporation and who owned the stock on the last day of that year; and (iii) under certain circumstances, a U.S. Person who acquires stock in a foreignnon-U.S. corporation and as a result thereof owns 10% or more of the voting power or value of such foreignnon-U.S. corporation, whether or not such foreignnon-U.S. corporation is a CFC. For any taxable year in which AGL determines that the 20% Gross Income Exception and the 20% Ownership Exception does not apply, AGL will provide to all U.S. Persons registered as shareholders of its shares a completed IRS Form 5471 or the relevant information necessary to complete the form.

Failure to file IRS Form 5471 may result in penalties. In addition, U.S. shareholders should consult their tax advisors with respect to other information reporting requirements that may be applicable to them.

U.S. Persons holding ourthe Company's shares should consider their possible obligation to file FINCEN Form 114, Foreign Bank and Financial Accounts Report, with respect to their shares. Additionally, such U.S. and non-U.S. persons should consider their possible obligations to annually report certain information with respect to usthe non-U.S. accounts with their U.S. federal income tax returns. Shareholders should consult their tax advisors with respect to these or any other reporting requirement which may apply with respect to their ownership of ourthe Company's shares.

Tax-Exempt Shareholders.    Tax-exempt entities will be required to treat certain subpart F insurance income, including RPII, that is includable in income by the tax-exempt entity as unrelated business taxable income. Prospective investors that are tax exempt entities are urged to consult their tax advisors as to the potential impact of the unrelated business taxable income provisions of the Code. A tax-exempt organization that is treated as a 10% U.S. Shareholder or a RPII Shareholder also must file IRS Form 5471 in certain circumstances.

Dispositions of AGL's Shares.    Subject to the discussions below relating to the potential application of the Code section 1248 and PFIC rules, holders of shares generally should recognize capital gain or loss for U.S. federal income tax purposes on the sale, exchange or other disposition of shares in the same manner as on the sale, exchange or other disposition of any other shares held as capital assets. If the holding period for these shares exceeds one year, any gain will be subject to tax at a current maximum marginal tax rate of 20% for individuals and 35%21% for corporations. Moreover, gain, if any, generally will be a U.S. source gain and generally will constitute "passive income" for foreign tax credit limitation purposes.

Code section 1248 provides that if a U.S. Person sells or exchanges stock in a foreignnon-U.S. corporation and such person owned, directly, indirectly through foreignnon-U.S. entities or constructively, 10% or more of the voting power of the corporation at any time during the five-year period ending on the date of disposition when the corporation was a CFC, any gain from the sale or exchange of the shares will be treated as a dividend to the extent of the CFC's earnings and profits (determined under U.S. federal income tax principles) during the period that the shareholder held the shares and while the corporation was a CFC (with

certain adjustments). The Company believes that because of the dispersion of AGL's share ownership, provisions in AGL's organizational documents that limit voting power and other factors that no U.S. shareholder of AGL should be treated as owning (directly, indirectly through foreignnon-U.S. entities or constructively) 10% ofor more of the total voting power or value of AGL; to the extent this is the case this application of Code Section 1248 under the regular CFC rules should not apply to dispositions of AGL's shares. It is possible, however, that the IRS could challenge the effectiveness of these provisions and that a court could sustain such a challenge. A 10% U.S. Shareholder may in certain circumstances be required to report a disposition of shares of a CFC by attaching IRS Form 5471 to the U.S. federal income tax or information return that it would normally file for the taxable year in which the disposition occurs. In the event this is determined necessary, AGL will provide a completed IRS Form 5471 or the relevant information necessary to complete the Form. Code section 1248 in conjunction with the RPII rules also applies to the sale or exchange of shares in a foreignnon-U.S. corporation if the foreignnon-U.S. corporation would be treated as a CFC for RPII purposes regardless of whether the shareholder is a 10% U.S. Shareholder or whether the 20% Ownership Exception or 20% Gross Income Exception applies. Existing proposed regulations do not address whether Code section 1248 would apply if a foreignnon-U.S. corporation is not a CFC but the foreignnon-U.S. corporation has a subsidiary that is a CFC and that would be taxed as an insurance company if it were a domestic corporation. The Company believes, however, that this application of Code section 1248 under the RPII rules should not apply to dispositions of AGL's shares because AGL will not be directly engaged in the insurance business. The Company cannot be certain, however, that the IRS will not interpret the proposed regulations in a contrary manner or that the Treasury Department will not amend the proposed regulations to provide that these rules will apply to dispositions of common shares. Prospective investors should consult their tax advisors regarding the effects of these rules on a disposition of common shares.

Passive Foreign Investment Companies.    In general, a foreignnon-U.S. corporation will be a PFIC during a given year if (i) 75% or more of its gross income constitutes "passive income" (the 75% test) or (ii) 50% or more of its assets produce passive income (the 50% test). and once characterized as a PFIC will generally retain PFIC status for future taxable years with respect to its U.S. shareholders in the taxable year of the initial PFIC characterization.

If AGL were characterized as a PFIC during a given year, each U.S. Person holding AGL's shares would be subject to a penalty tax at the time of the sale at a gain of, or receipt of an "excess distribution" with respect to, their shares, unless such person (i) is a 10% U.S. Shareholder and AGL is a CFC or (ii) made a "qualified electing fund election" or "mark-to-market" election. It is uncertain that AGL would be able to provide its shareholders with the information necessary for a U.S. Person to make a qualified electing fund election. In addition, if AGL were considered a PFIC, upon the death of any U.S. individual owning common shares, such individual's heirs or estate would not be entitled to a "step-up" in the basis of the common shares that might otherwise be available under U.S. federal income tax laws. In general, a shareholder receives an "excess distribution" if the amount of the distribution is more than 125% of the average distribution with respect to the common shares during the three preceding taxable years (or shorter period during which the taxpayer held common shares). In general, the

penalty tax is equivalent to an interest charge on taxes that are deemed due during the period the shareholder owned the common shares, computed by assuming that the excess distribution or gain (in the case of a sale) with respect to the common shares was taken in equal portion at the highest applicable tax rate on ordinary income throughout the shareholder's period of ownership. The interest charge is equal to the applicable rate imposed on underpayments of U.S. federal income tax for such period. In addition, a distribution paid by AGL to U.S. shareholders that is characterized as a dividend and is not characterized as an excess distribution would not be eligible for reduced rates of tax as qualified dividend income. A U.S. Person that is a shareholder in a PFIC may also be subject to additional information reporting requirements, including the annual filing of IRS Form 8621.

For the above purposes, passive income generally includes interest, dividends, annuities and other investment income. The PFIC rules, as amended by the Tax Act, provide that income "derivedderived in the active conduct of an insurance business by a corporation which is predominantly engaged in anqualifying insurance business...corporation is not treated as passive income." The PFIC provisions also contain a look-through rule under which a foreignnon-U.S. corporation shall be treated as if it "received directly its proportionate share of the income..." and as if it "held its proportionate share of the assets..." of any other corporation in which it owns at least 25% of the value of the stock. A second PFIC look-through rule would treat stock of a U.S. corporation owned by another U.S. corporation which is at least 25% owned (by value) by a non-U.S. corporation as a non-passive asset that generates non-passive income for purposes of determining whether the non-U.S. corporation is a PFIC.

The insurance income exception isoriginally was intended to ensure that income derived by a bona fide insurance company is not treated as passive income, except to the extent such income is attributable to financial reserves in excess of the reasonable needs of the insurance business. The Company expects, for purposes of the PFIC rules, that each of AGL's insurance subsidiaries will be predominantly engaged in an insurance business and is unlikely to have financial reserves in excess of the reasonable needs of its insurance business in each year of operations. Accordingly, noneHowever, the Tax Act limits the insurance income exception to a non-U.S. insurance company that is a qualifying insurance corporation that would be taxable as an insurance company if it were a U.S. corporation and maintains insurance liabilities of more than 25% of such company’s assets for a taxable year (or maintains insurance liabilities that at least equal or exceed 10% of its assets and it satisfies a facts and circumstances test that requires a showing that the income or assets of AGL's insurance subsidiaries should be treated as passive. Additionally, the Company expects that in each year of operations the passive income and assets of AGL's non-insurance subsidiaries will notfailure to exceed the 75% test25% threshold is due to run-off or 50% test amounts in each year of operations with respect to the overall income and assets of AGL and its subsidiaries. Under the look-through rule AGL should be deemed to own its proportionate share of the assets and to have received its proportionate share of the income of its direct and indirect subsidiaries for purposes of the 75% test and the 50% test. As a result, the Company believes that AGL was

not and should not be treated as a PFIC. The Company cannot be certain thatrating agency circumstances) (the Reserve Test). Further, the IRS will not successfully challenge this position, however, as there are currently no final or temporary regulations regarding the application of the PFIC provisions to an insurance company. The IRS recently issued proposed regulations in 2015 intended to clarify the application of the PFIC provisions to an insurance company. These proposed regulations provide that a non-U.S. insurance company may only qualify for an exception to the PFIC rules if, among other things, the non-U.S. insurance company’s officers and employees perform its substantial managerial and operational activities. This proposed regulation will not be effective until adopted in final form. BecauseThe Company believes that, based on the application of the legal uncertainties relating to how the proposed regulations will be interpretedPFIC look-through rules described above and the form in which such regulations mayCompany's plan of operations for the current and future years, AGL should not be finalized, or whether any legislation will be proposed to limit the insurance company exception,characterized as a PFIC. However, as the Company cannot predict whatthe likelihood of finalization of the proposed regulations or the scope, nature, or impact if any, such guidanceof the proposed regulations on us, should they be formally adopted or legislation would have on an investorenacted or whether the Company's non-U.S. insurance subsidiaries will be able to satisfy the Reserve Test in future years and the interaction of the PFIC look-through rules is not clear, no assurance may be given that is subject to U.S. federal income tax.the Company will not be characterized as a PFIC. Prospective investors should consult their tax advisor as to the effects of the PFIC rules.

Foreign tax credit.    If U.S. Persons own a majority of AGL's common shares, only a portion of the current income inclusions, if any, under the CFC, RPII and PFIC rules and of dividends paid by AGL (including any gain from the sale of common shares that is treated as a dividend under section 1248 of the Code) will be treated as foreign source income for purposes of computing a shareholder's U.S. foreign tax credit limitations. The Company will consider providing shareholders with information regarding the portion of such amounts constituting foreign source income to the extent such information is reasonably available. It is also likely that substantially all of the "subpart F income," RPII and dividends that are foreign source income will constitute either "passive" or "general" income. Thus, it may not be possible for most shareholders to utilize excess foreign tax credits to reduce U.S. tax on such income.

Information Reporting and Backup Withholding on Distributions and Disposition Proceeds.    Information returns may be filed with the IRS in connection with distributions on AGL's common shares and the proceeds from a sale or other disposition of AGL's common shares unless the holder of AGL's common shares establishes an exemption from the information reporting rules. A holder of common shares that does not establish such an exemption may be subject to U.S. backup withholding tax on these payments if the holder is not a corporation or non-U.S. Person or fails to provide its taxpayer identification number or otherwise comply with the backup withholding rules. The amount of any backup withholding from a payment to a U.S. Person will be allowed as a credit against the U.S. Person's U.S. federal income tax liability and may entitle the U.S. Person to a refund, provided that the required information is furnished to the IRS.

Changes in U.S. Federal Income Tax Law Could Materially Adversely Affect AGL or AGL's Shareholders. Legislation has been introduced from time to time in the U.S. Congress intended to eliminate certain perceived tax advantages of companies (including insurance companies) that have legal domiciles outside the U.S. but have certain U.S. connections. It is possible that legislation could be introduced in and enacted by the current Congress or future Congress that could have an adverse impact on AGL or AGL's shareholders. For example, legislation has been introduced in Congress to limit the deductibility of reinsurance premiums paid by U.S. companies to foreign affiliates. Further, legislation based on the Tax Reform Task-Force Blueprint dated June 24, 2016, which recommends moving to a cash flow consumption-based tax system and provides for border adjustments taxing imports may be introduced and enacted and its impact on the insurance industry may adversely impact the results of our operations.

Additionally, tax laws and interpretations regarding whether a company is engaged in a U.S. trade or business or whether a company is a CFC or a PFIC or has RPII are subject to change, possibly on a retroactive basis. There are currently only recently proposed regulations regarding the application of the PFIC rules to an insurance company. Additionally, the regulations regarding RPII have been in proposed form since 1991. New regulations or pronouncements interpreting or clarifying such rules may be forthcoming. The Company cannot be certain if, when or in what form such regulations or pronouncements may be provided and whether such guidance will have a retroactive effect.

United Kingdom

The following discussion is intended to be only a general guide to certain U.K. tax consequences of holding AGL common shares, under current law and the current practice of HMRC, either of which is subject to change at any time, possibly with retrospective effect. Except where otherwise stated, this discussion applies only to shareholders who are not (and have not recently been) resident or (in the case of individuals) domiciled for tax purposes in the U.K., who hold their AGL common shares as an investment and who are the absolute beneficial owners of their common shares. This discussion may not apply to certain shareholders, such as dealers in securities, life insurance companies, collective investment schemes, shareholders who are exempt from tax and shareholders who have (or are deemed to have) acquired their shares by virtue of an office or employment. Such shareholders may be subject to special rules.


The following statements do not purport to be a comprehensive description of all the U.K. considerations that may be relevant to any particular shareholder. Any person who is in any doubt as to their tax position should consult an appropriate professional tax adviser.

AGL's Tax Residency. AGL is not incorporated in the U.K., but effective November 6, 2013, the AGL Board manages its affairs with the intent to maintain its status as a company that is tax resident in the U.K.

Dividends. Under current U.K. tax law, AGL is not required to withhold tax at source from dividends paid to the holders of the AGL common shares.

Capital gains. U.K. tax is not normally charged on any capital gains realized by non-U.K. shareholders in AGL unless, in the case of a corporate shareholder, at or before the time the gain accrues, the shareholding is used in or for the purposes of a trade carried on by the non-resident shareholder through a permanent establishment in the U.K. or for the purposes of that permanent establishment. Similarly, an individual shareholder who carries on a trade, profession or vocation in the U.K. through a branch or agency may be liable for U.K. tax on the gain if such shareholder disposes of shares that are, or have been, used, held or acquired for the purposes of such trade, profession or vocation or for the purposes of such branch or agency. This treatment applies regardless of the U.K. tax residence status of AGL.

Stamp Taxes. On the basis that AGL does not currently intend to maintain a share register in the U.K., there should be no U.K. stamp duty reserve tax on a purchase of common shares in AGL. A conveyance or transfer on sale of common shares in AGL will not be subject to U.K. stamp duty, provided that the instrument of transfer is not executed in the U.K. and does not relate to any property situated, or any matter or thing done, or to be done, in the U.K.

Description of Share Capital

The following summary of AGL's share capital is qualified in its entirety by the provisions of Bermuda law, AGL's memorandum of association and its Bye-Laws, copies of which are incorporated by reference as exhibits to this Annual Report on Form 10-K.

AGL's authorized share capital of $5,000,000 is divided into 500,000,000 shares, par value U.S. $0.01 per share, of which 124,958,756103,026,253 common shares were issued and outstanding as of February 21, 2017.26, 2019. Except as described below, AGL's common shares have no pre-emptive rights or other rights to subscribe for additional common shares, no rights of redemption, conversion or exchange and no sinking fund rights. In the event of liquidation, dissolution or winding-up, the holders of AGL's common shares are entitled to share equally, in proportion to the number of common shares held by such holder, in AGL's assets, if any remain after the payment of all AGL's debts and liabilities and the liquidation preference of any outstanding preferred shares. Under certain circumstances, AGL has the right to purchase all or a portion of the shares held by a shareholder. See "—Acquisition of Common Shares by AGL" below.

Voting Rights and Adjustments

In general, and except as provided below, shareholders have one vote for each common share held by them and are entitled to vote with respect to their fully paid shares at all meetings of shareholders. However, if, and so long as, the common shares (and other of AGL's shares) of a shareholder are treated as "controlled shares" (as determined pursuant to section 958 of the Code) of any U.S. Person and such controlled shares constitute 9.5% or more of the votes conferred by AGL's issued and outstanding shares, the voting rights with respect to the controlled shares owned by such U.S. Person shall be limited, in the aggregate, to a voting power of less than 9.5% of the voting power of all issued and outstanding shares, under a formula specified in AGL's Bye-laws. The formula is applied repeatedly until there is no U.S. Person whose controlled shares constitute 9.5% or more of the voting power of all issued and outstanding shares and who generally would be required to recognize

income with respect to AGL under the Code if AGL were a CFC as defined in the Code and if the ownership threshold under the Code were 9.5% (as defined in AGL's Bye-Laws as a 9.5% U.S. Shareholder). In addition, AGL's Board may determine that shares held carry different voting rights when it deems it appropriate to do so to (i) avoid the existence of any 9.5% U.S. Shareholder; and (ii) avoid adverse tax, legal or regulatory consequences to AGL or any of its subsidiaries or any direct or indirect holder of shares or its affiliates. "Controlled shares" includes, among other things, all shares of AGL that such U.S. Person is deemed to own directly, indirectly or constructively (within the meaning of section 958 of the Code). Further, these provisions do not apply in the event one shareholder owns greater than 75% of the voting power of all issued and outstanding shares.

Under these provisions, certain shareholders may have their voting rights limited to less than one vote per share, while other shareholders may have voting rights in excess of one vote per share. Moreover, these provisions could have the effect of

reducing the votes of certain shareholders who would not otherwise be subject to the 9.5% limitation by virtue of their direct share ownership. AGL's Bye-laws provide that it will use its best efforts to notify shareholders of their voting interests prior to any vote to be taken by them.

AGL's Board is authorized to require any shareholder to provide information for purposes of determining whether any holder's voting rights are to be adjusted, which may be information on beneficial share ownership, the names of persons having beneficial ownership of the shareholder's shares, relationships with other shareholders or any other facts AGL's Board may deem relevant. If any holder fails to respond to this request or submits incomplete or inaccurate information, AGL's Board may eliminate the shareholder's voting rights. All information provided by the shareholder will be treated by AGL as confidential information and shall be used by AGL solely for the purpose of establishing whether any 9.5% U.S. Shareholder exists and applying the adjustments to voting power (except as otherwise required by applicable law or regulation).

Restrictions on Transfer of Common Shares

AGL's Board may decline to register a transfer of any common shares under certain circumstances, including if they have reason to believe that any adverse tax, regulatory or legal consequences to the Company, any of its subsidiaries or any of its shareholders or indirect holders of shares or its Affiliates may occur as a result of such transfer (other than such as AGL's Board considers de minimis). Transfers must be by instrument unless otherwise permitted by the Companies Act.

The restrictions on transfer and voting restrictions described above may have the effect of delaying, deferring or preventing a change in control of Assured Guaranty.

Acquisition of Common Shares by AGL

Under AGL's Bye-Laws and subject to Bermuda law, if AGL's Board determines that any ownership of AGL's shares may result in adverse tax, legal or regulatory consequences to AGL, any of AGL's subsidiaries or any of AGL's shareholders or indirect holders of shares or its Affiliates (other than such as AGL's Board considers de minimis), AGL has the option, but not the obligation, to require such shareholder to sell to AGL or to a third party to whom AGL assigns the repurchase right the minimum number of common shares necessary to avoid or cure any such adverse consequences at a price determined in the discretion of the Board to represent the shares' fair market value (as defined in AGL's Bye-Laws).

Other Provisions of AGL's Bye-Laws

AGL's Board and Corporate Action

AGL's Bye-Laws provide that AGL's Board shall consist of not less than three and not more than 21 directors, the exact number as determined by the Board. AGL's Board consists of ten persons who are elected for annual terms.

Shareholders may only remove a director for cause (as defined in AGL's Bye-Laws) at a general meeting, provided that the notice of any such meeting convened for the purpose of removing a director shall contain a statement of the intention to do so and shall be provided to that director at least two weeks before the meeting. Vacancies on the Board can be filled by the Board if the vacancy occurs in those events set out in AGL's Bye-Laws as a result of death, disability, disqualification or resignation of a director, or from an increase in the size of the Board.

Generally under AGL's Bye-Laws, the affirmative votes of a majority of the votes cast at any meeting at which a quorum is present is required to authorize a resolution put to vote at a meeting of the Board, including one relating to a merger, acquisition or business combination. Corporate action may also be taken by a unanimous written resolution of the Board

without a meeting. A quorum shall be at least one-half of directors then in office present in person or represented by a duly authorized representative, provided that at least two directors are present in person.

Shareholder Action

At the commencement of any general meeting, two or more persons present in person and representing, in person or by proxy, more than 50% of the issued and outstanding shares entitled to vote at the meeting shall constitute a quorum for the transaction of business. In general, any questions proposed for the consideration of the shareholders at any general meeting shall be decided by the affirmative votes of a majority of the votes cast in accordance with the Bye-Laws.

The Bye-Laws contain advance notice requirements for shareholder proposals and nominations for directors, including when proposals and nominations must be received and the information to be included.

Amendment

The Bye-Laws may be amended only by a resolution adopted by the Board and by resolution of the shareholders.

Voting of Non-U.S. Subsidiary Shares

IfWhen AGL is required or entitled to vote at a general meeting (for example, an annual meeting) of any of AG Re, AGFOL or any other of its directly held non-U.S. subsidiaries, AGL's Board shallis required to refer the subject matter of the vote to AGL's shareholders and seek direction from such shareholders as to how they should vote on the resolution proposed by the non-U.S. subsidiary. AGL's Board in its discretion shall require that substantially similar provisions are or will be contained in the bye-laws (or equivalent governing documents) of any direct or indirect non-U.S. subsidiaries other than U.K.AGRO and AGRO.subsidiaries incorporated in the U.K.

Employees

As of December 31, 2016,2018, the Company had approximately 300312 employees. None of the Company's employees are subject to collective bargaining agreements. The Company believes that employee relations are satisfactory.

ITEM 1A.RISK FACTORS

You should carefully consider the following information, together with the information contained in AGL's other filings with the SEC. The risks and uncertainties discussed below are not the only ones the Company faces. However, these are the risks that the Company's management believes are material. The Company may face additional risks or uncertainties that are not presently known to the Company or that management currently deems immaterial, and such risks or uncertainties also may impair its business or results of operations. The risks discussed below could result in a significant or material adverse effect on the Company's financial condition, results of operations, liquidity or business prospects.

Risks Related to the Company's Expected Losses

Estimates of expected losses are subject to uncertainties and may not be adequate to cover potential paid claims.

The financial guaranties issued by the Company's insurance subsidiaries insure the credit performance of the guaranteed obligations over an extended period of time, in some cases over 30 years, and, in most circumstances, the Company has no right to cancel such financial guaranties. As a result, the Company's estimate of ultimate losses on a policy is subject to significant uncertainty over the life of the insured transaction. Credit performance can be adversely affected by economic, fiscal and financial market variability as well as changes in law or industry practices (such as the potential discontinuance of the publication of the London Interbank Offered Rate (LIBOR)) over the long duration of most contracts. If the Company's actual losses exceed its current estimate, this may result in adverse effects on the Company's financial condition, results of operations, liquidity, business prospects, financial strength ratings and ability to raise additional capital.

The determination of expected loss is an inherently subjective process involving numerous estimates, assumptions and judgments by management, using both internal and external data sources with regard to frequency, severity of loss, economic projections, the perceived strength of legal protections, governmental actions, negotiations and other factors that affect credit performance. The Company does not use traditional actuarial approaches to determine its estimates of expected losses. Actual losses will ultimately depend on future events or transaction performance. As a result, the Company's current estimates of probable and estimable losses may not reflect the Company's future ultimate claims paid.

Certain sectors and large risks within the Company's insured portfolio have experienced credit deterioration in excess of the Company’s initial expectations, which has led or may lead to losses in excess of the Company’s initial expectations.  The Company's expected loss models take into account current and expected future trends, which contemplate the impact of current and probable developments in the performance of the credit.exposure.  These factors, which are integral elements of the Company's reserve estimation methodology, are updated on a quarterly basis based on current information.  Because such information changes over time, sometimes materially, from quarter to quarter, the Company’s projection of losses may also change materially. SinceMuch of the financial crisis, much of therecent development in the Company’sCompany's loss projections was with respectrelate to insured U.S. RMBS securities.  While the Company's net par outstanding of U.S. RMBS rated BIG under the Company's rating methodology as of December 31, 2016 and December 31, 2015 was still $3.2 billion and $4.0 billion, respectively, and may still be a source of loss development, the Company believes the performance of this portfolio has stabilized.  More recently, there has been credit deterioration with respect to certain insured Puerto Rico credits.exposures. The Company had net par outstanding to general obligation bonds of the Commonwealth of Puerto Rico and various obligations of its related authorities and public corporations as of December 31, 2018 and December 31, 2017 aggregating to $4.8 billion and $5.1$5.0 billion, respectively, as of December 31, 2016 and December 31, 2015, all of which was rated BIG under the Company’s rating methodology as of December 31, 2016.methodology. For a discussion of the Company's Puerto Rico risks, and RMBS transactions, see Part II, Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure.

Most of the insurer'sPuerto Rican entities with obligations insured by the Company have defaulted on their debt service payments, and the Company has paid claims on them.

On June 30, 2016, the Puerto Rico Oversight, Management, and Economic Stability Act (PROMESA) was signed into law by the President of the United States. PROMESA established a seven-member federal financial strengthoversight board (Oversight Board) with authority to require that balanced budgets and abilityfiscal plans be adopted and implemented by Puerto Rico. PROMESA provides a legal framework under which the debt of the Commonwealth and its related authorities and public corporations may be voluntarily restructured, and grants the Oversight Board the sole authority to meet ongoing obligationsfile restructuring petitions in a federal court to policyholdersrestructure the debt of the Commonwealth and cedantsits related authorities and public corporations if voluntary

negotiations fail, provided that any such restructuring must be in accordance with an Oversight Board approved fiscal plan that respects the terms of the financial guaranties it has issued or the reinsurance agreements it has executed. The ratings also reflect qualitative factors, such as the rating agencies' opinion of an insurer's business strategyliens and franchise value, the anticipated future demand for its product, the composition of its insured portfolio, and its capital adequacy, profitability and financial flexibility. Issuers, investors, underwriters, ceding companies and others consider the Company's financial strength or financial enhancement ratings an important factor when deciding whether or not to utilize a financial guaranty or purchase reinsurance from one of the insurance or reinsurance subsidiaries. A downgrade by a rating agency of the financial strength or financial enhancement ratings of one or more of AGL's subsidiariespriorities provided under Puerto Rico law.

could impair the Company's financial condition, results of operation, liquidity, business prospects or other aspects of the Company's business.

The ratings assigned by the rating agencies that publish financial strength or financial enhancement ratings on AGL's insurance subsidiaries are subject to frequent review and may be lowered by a rating agency as a result of a number of factors, including, but not limited to, the rating agency's revised stress loss estimates for the Company's insurance portfolio, adverse developments in the Company's or the subsidiary's financial conditions or results of operations due to underwriting or investment losses or other factors, changes in the rating agency's outlook for the financial guaranty industry or in the markets in which the Company operates, or a revision in the rating agency's capital model or ratings methodology. Their reviews can occur at any time and without notice to the Company and could result in a decision to downgrade, revise or withdraw the financial strength or financial enhancement ratings of AGL's insurance and reinsurance subsidiaries. For example, while all of the rating agencies that rate AGL subsidiaries with exposure to Puerto Rico have indicated that their evaluations of such AGL subsidiaries already take into account stress scenarios related to developmentsOn September 20, 2017, Hurricane Maria made landfall in Puerto Rico actual developments in Puerto Rico beyond what a rating agency considered could cause that rating agency to review its ratings of such AGL subsidiaries.

Since 2008, each of S&P and Moody's has reviewed and downgraded the financial strength ratings of AGL's insurance and reinsurance subsidiaries, including AGC, AGM and AG Re. In addition, S&P and Moody's have from time to time changed the ratings outlook for certain of the Company's subsidiaries to "negative" from "stable" or have placed such ratings on watch for possible downgrade. Currently, AGM, AGC, MAC and AG Re all have AA (Stable Outlook) financial strength ratings from S&P, with the most recent change by S&P being an upgrade of AGC, AGM and AG Re from AA- (Stable Outlook) in November 2011.  Each of AGM and MAC also has a AA+ (Stable Outlook) and AGC also has a AA (Stable Outlook) financial strength rating from KBRA, while AGM and AGC have financial strength ratings in the single-A category from Moody's (A2 (Stable Outlook) and A3 (Stable Outlook), respectively), with the most recent ratings change by Moody's being a change in the outlook of AGC to Stable in August 2016. In addition, AGRO has been assigned a rating of A+ (Stable) from Best, which is Best's second highest rating. The Company periodically assesses the value of each rating assigned to each of its companies, and may as a resultCategory 4 hurricane on the Saffir-Simpson scale, causing loss of such assessment request that a rating agency add or drop a rating from certainlife and widespread devastation. Damage to the Commonwealth’s infrastructure, including the power grid, water system and transportation system, was extensive, and has impacted the ability and willingness of its companies. For example,Puerto Rican obligors to make timely and full debt service payments and participants’ efforts to resolve the KBRA ratings were first assigned to MAC in 2013 and to AGM in 2014 and the Best rating was first assigned to AGRO in 2015, while a Moody's rating was never requested for MAC and was dropped from AG Re and AGRO in 2015. On January 13, 2017, AGC announced that it had requested that Moody's withdraw itsCommonwealth’s financial strength rating of AGC.issues under PROMESA.

Any adverse decisions in litigation relating to Puerto Rico may impact both the Company's new business opportunitiesexposure in Puerto Rico as well as the strength of its legal protections in other exposures. For example, on January 30, 2018, the Federal District Court in Puerto Rico held, in an action initiated by the Company relating to the Puerto Rico Highways and have also affectedTransportation Authority (PRHTA), among other things, that (i) even though the valuespecial revenue provisions of the Company's productBankruptcy Code protect a lien on pledged special revenues, those provisions do not mandate the turnover of pledged special revenues to issuersthe payment of bonds and investors.

Under interest rate swaps insured by AGM, further downgrades past specified rating levels could entitle the municipal obligor's swap counterparty to terminate the swap; if the municipal obligor owed a termination payment as a result and were unable to make such payment, AGM may receive a claim if its financial guaranty guaranteed such termination payment.

Additional information about increased claim payments the CompanyCompany's exposure to Puerto Rico and legal actions it has initiated may potentially make, seebe found in Part II, Item 8, Financial Statements and Supplementary Data, Note 6, Contracts Accounted for as Insurance, Ratings Impact on Financial Guaranty Business. In certain other transactions, beneficiaries of financial guaranties issued by the Company's insurance subsidiaries may have the right to cancel the credit protection offered by the Company, which would result in the loss of future premium earnings and the reversal of any fair value gains recorded by the Company. In addition, a downgrade of AG Re or AGC could result in certain ceding companies recapturing business that they had ceded to these reinsurers. See "The downgrade of the financial strength ratings of AG Re or of AGC gives certain reinsurance counterparties the right to recapture ceded business, which would lead to a reduction in the Company's unearned premium reserve and related earnings on such reserve" below.

If AGM's financial strength or financial enhancement ratings were downgraded, AGM-insured GICs issued by the former AGMH subsidiaries that conducted AGMH's Financial Products Business (the Financial Products Companies) may

come due or may come due absent the posting of collateral by the GIC issuers. The Company relies on agreements pursuant to which Dexia has agreed to guarantee or lend certain amounts, or to post liquid collateral, in regards to AGMH's former financial products business. See "Risks Related to the Company's Business, Acquisitions may subject the Company to non-monetary consequences."

Furthermore, if the financial strength ratings of AGE or AGUK were downgraded, AGM or AGC may be required to contribute additional capital to their respective subsidiary pursuant to the terms of the support arrangements for such subsidiaries, including those described in "Item 1. Business, Regulation, United Kingdom, Material Contracts."

The downgrade of the financial strength ratings of AG Re or of AGC gives certain reinsurance counterparties the right to recapture ceded business, which would lead to a reduction in the Company's unearned premium reserve and related earnings on such reserve.

The downgrade of the financial strength ratings of AG Re or of AGC gives certain reinsurance counterparties the right to recapture ceded business, which would lead to a reduction in the Company's unearned premium reserve and related earnings on such reserve. With respect to a significant portion of the Company's in-force financial guaranty assumed business, based on AG Re's and AGC's current ratings and subject to the terms of each reinsurance agreement, the third party ceding company may have the right to recapture assumed business ceded to AG Re and/or AGC, and in connection therewith, to receive payment from the assuming reinsurer of an amount equal to the reinsurer’s statutory unearned premium (net of ceding commissions) and statutory loss reserves (if any) associated with that business, plus, in certain cases, an additional ceding commission. As of December 31, 2016, if each third party company ceding business to AG Re and/or AGC had a right to recapture such business, and chose to exercise such right, the aggregate amounts that AG Re and AGC could be required to pay to all such companies would be approximately $45 million and $18 million, respectively.

Actions taken by the rating agencies with respect to capital models and rating methodology of the Company's business or changes in capital charges or downgrades of transactions within its insured portfolio may adversely affect its ratings, business prospects, results of operations and financial condition.

The rating agencies from time to time have evaluated the Company's capital adequacy under a variety of scenarios and assumptions. The rating agencies do not always supply clear guidance on their approach to assessing the Company's capital adequacy and the Company may disagree with the rating agencies' approach and assumptions. For example, S&P assesses each individual credit (including potential new credits) insured by the Company based on a variety of factors, including the nature of the credit, the nature of the support or credit enhancement for the credit, its tenor, and its expected and actual performance. This assessment determines the amount of capital the Company is required to maintain against that credit to maintain its financial strength ratings under S&P's capital adequacy model. Sometimes the rating agencies consider the amount of additional capital that could be required for certain risks or sectors under certain stress scenarios based on their views of developments in the market, as each have done recently with respect to the Company's exposures4, Outstanding Exposure, Exposure to Puerto Rico. Factors influencing the rating agencies are beyond management's control and not always known to the Company. In the event of an actual or perceived deterioration in creditworthiness, or a change in a rating agency's capital model or rating methodology, that rating agency may require the Company to increase the amount of capital allocated to support the affected credits, regardless of whether losses actually occur, or against potential new business. Significant reductions in the rating agencies' assessments of credits in the Company's insured portfolio can produce significant increases in the amount of capital required for the Company to maintain its financial strength ratings under the rating agencies' capital adequacy models, which may require the Company to seek additional capital. The amount of such capital required may be substantial, and may not be available to the Company on favorable terms and conditions or at all. Accordingly, the Company cannot ensure that it will seek to, or be able to, raise additional capital. The failure to raise additional required capital could result in a downgrade of the Company's ratings and thus have an adverse impact on its business, results of operations and financial condition. See "Risks Related to the Company's Capital and Liquidity Requirements—The Company may require additional capital from time to time, including from soft capital and liquidity credit facilities, which may not be available or may be available only on unfavorable terms."

Risks Related to the Financial, Credit and Financial Guaranty Markets

The Company's business, liquidity, financial condition and stock price may be adversely affected by developments in the U.S. and world-wide financial markets.

The Company's loss reserves, profitability, financial position, insured portfolio, investment portfolio, cash flow, statutory capital and stock price could be materially affected by the U.S. and global financial markets. Upheavals in the financial markets affect economic activity and employment and therefore can affect the Company's business. The global economic outlook remains uncertain, including the overall growth rate of the U.S. economy, the fragile economic recoveryimpact of Brexit in

Europe and the impact of recent political trends on the global economic order. These and other risks could materially and negatively affect the Company’s ability to access the capital markets, the cost of the Company's debt, the demand for its products, the amount of losses incurred on transactions it guarantees, the value of its investment portfolio (including its alternative investments), its financial ratings and the price of its common shares.

Some of the state and local governments and entities that issue obligations the Company insures are experiencing significant budget deficits and pension funding and revenue shortfalls that could result in increased credit losses or impairments and capital charges on those obligations.

Some of the state and local governments that issue the obligations the Company insures have experienced significant budget deficits and pension funding and revenue collection shortfalls that required them to significantly raise taxes and/or cut spending in order to satisfy their obligations. While the U.S. government has provided some financial support and although overall state revenues have increased in recent years, significant budgetary pressures remain, especially at the local government level and in relation to retirement obligations. Certain local governments, including ones that have issued obligations insured by the Company, have sought protection from creditors under chapter 9 of the U.S. Bankruptcy Code as a means of restructuring their outstanding debt. In some recent instances where local governments were seeking to restructure their outstanding debt, and partially in response to concerns that materially reducing pension payments would lead to employee flight and, therefore, an inadequate level of local government services, pension and other obligations owed to workers were treated more favorably than senior bond debt owed to the capital markets. If the issuers of the obligations in the Company's public finance portfolio do not have sufficient funds to cover their expenses and are unable or unwilling to raise taxes, decrease spending or receive federal assistance, the Company may experience increased levels of losses or impairments on its public finance obligations, which could materially and adversely affect its business, financial condition and results of operations. If such issuers succeed in restructuring pension and other obligations owed to workers so that they are treated more favorably than obligations insured by the Company, such losses or impairments could be greater than the Company otherwise anticipated when the insurance was written.


The Company's risk of loss on and capital charges for municipal creditsexposures could also be exacerbated by rating agency downgrades of municipal creditexposure ratings. A downgraded municipal issuer may be unable to refinance maturing obligations or issue new debt, which could reduce the municipality's ability to service its debt. Downgrades could also affect the interest rate that the municipality must pay on its variable rate debt or for new debt issuance. Municipal creditexposure downgrades, as with other downgrades, result in an increase in the capital charges the rating agencies assess when evaluating the Company's capital adequacy in their rating models. Significant municipal downgrades could result in higher capital requirements for the Company in order to maintain its financial strength ratings.

The Company has an aggregate $4.8 billion net par exposure as of December 31, 2016 to the Commonwealth of Puerto Rico (Puerto Rico or the Commonwealth) and various obligations of its related authorities and public corporations, and claim payments on such insured exposures in excess of that expected by the Company could have a negative effect on the Company's liquidity and results of operations. On January 1, 2016, Puerto Rico Infrastructure Finance Authority (PRIFA) defaulted on payment of a portion of the interest due on its bonds on that date. There have been additional payment defaults by Puerto Rico issuers since then, and the Company has made claim payments with respect to several Puerto Rico credits. On April 6, 2016, Governor García Padilla of Puerto Rico (the Former Governor) signed into law the Puerto Rico Emergency Moratorium & Financial Rehabilitation Act (the Moratorium Act). The Moratorium Act purportedly empowers the governor to declare, entity by entity, states of emergencies and moratoriums on debt service payments on obligations of the Commonwealth and its related authorities and public corporations, as well as instituting a stay against related litigation, among other things. The Former Governor used the authority of the Moratorium Act to take a number of actions related to issuers of obligations the Company insures. On June 30, 2016, the Puerto Rico Oversight, Management, and Economic Stability Act (PROMESA) was signed into law by the President of the United States. PROMESA establishes a seven-member federal financial oversight board (Oversight Board) with authority to require that balanced budgets and fiscal plans be adopted and implemented by Puerto Rico. PROMESA provides a legal framework under which the debt of the Commonwealth and its related authorities and public corporations may be voluntarily restructured, and grants the Oversight Board the sole authority to file restructuring petitions in a federal court to restructure the debt of the Commonwealth and its related authorities and public corporations if voluntary negotiations fail, provided that any such restructuring must be in accordance with an Oversight Board approved fiscal plan that respects the liens and priorities provided under Puerto Rico law. The Oversight Board has begun meeting and has hired Ramón Ruiz-Comas as interim executive director. On January 2, 2017, Ricardo Antonio Rosselló Nevares (the Governor) took office, replacing the Former Governor. On January 29, 2017, the Governor signed the Puerto Rico Emergency and Fiscal Responsibility Act (Emergency Act) that, among other things, repeals portions of the Moratorium Act, defines an emergency period until May 1, 2017, continues diversion of collateral away from bonds the Company insures, and defines the powers and duties of the Fiscal Agency and Financial Advisory Authority (FAFAA). The final shape, timing and validity of responses to Puerto Rico’s distress eventually enacted or implemented under the auspices of PROMESA and the Oversight Board or

otherwise, and the impact of any such responses on obligations insured by the Company, is uncertain. Additional information about the Company's exposure to Puerto Rico may be found in Part II, Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure, Exposure to Puerto Rico.
In addition, obligations supported by specified revenue streams, such as revenue bonds issued by toll road authorities, municipal utilities or airport authorities, may be adversely affected by revenue declines resulting from reduced demand, changing demographics or other factors associated with an economy in which unemployment remains high, housing prices have not yet stabilized and growth is slow. These obligations, which may not necessarily benefit from financial support from other tax revenues or governmental authorities, may also experience increased losses if the revenue streams are insufficient to pay scheduled interest and principal payments.

Persistently low interest rate levels and credit spreads could adversely affect demand for financial guaranty insurance as well as the Company's financial condition.

Demand for financial guaranty insurance generally fluctuates with changes in market credit spreads. Credit spreads, which are based on the difference between interest rates on high-quality or "risk free" securities versus those on lower-rated or uninsured securities, fluctuate due to a number of factors and are sensitive to the absolute level of interest rates, current credit experience and investors' risk appetite. Average municipal interest rates were extremely low duringWhile higher than in 2016, withwhen the benchmark AAA 30-year Municipal Market DataMMD index published by Thomson Reuters (MMD Index),was at times below 2%, a threshold not previously crossedthe average for that rate was 3.05% in the modern era.2018, still low by historical standards. When interest rates are low, or when the market is relatively less risk averse, the credit spread between high-quality or insured obligations versus lower- rated or uninsured obligations typically narrows. As a result, financial guaranty insurance typically provides lower interest cost savings to issuers than it would during periods of relatively wider credit spreads. When issuersIssuers are less likely to use financial guaranties on their new issues when credit spreads are narrow, this results in decreased demand or premiums obtainable for financial guaranty insurance, and a resulting reduction in the Company's results of operations. The continued persistence of low interest rate levels and or low credit spreads by historical standards could continue to dampen demand for financial guaranty insurance.

Conversely, in a deteriorating credit environment, credit spreads increase and become "wide", which increases the interest cost savings that financial guaranty insurance may provide and can result in increased demand for financial guaranties by issuers. However, if the weakening credit environment is associated with economic deterioration, the Company's insured portfolio could generate claims and loss payments in excess of normal or historical expectations. In addition, increases in market interest rate levels could reduce new capital markets issuances and, correspondingly, a decreased volume of insured transactions.

Competition in the Company's industry may adversely affect its revenues.

As described in greater detail under "Competition" in "Item 1. Business," the Company can face competition, either in the form of current or new providers of credit enhancement or in terms of alternative structures, including uninsured offerings, or pricing competition. Increased competition could have an adverse effect on the Company's insurance business.

The Company's financial position, results of operations and cash flows may be adversely affected by fluctuations in foreign exchange rates.

The Company's reporting currency is the U.S. dollar. The functional currencies of AGL's primary insurance and reinsurance subsidiaries are the U.S. dollar and pound sterling. Exchange rate fluctuations may materially impact the Company's financial position, results of operations and cash flows.dollar. The Company's non-U.S. subsidiaries maintain both assets and liabilities in currencies different from their functional currency, which exposes the Company to changes in currency exchange rates. In addition, locally-required capital levelsassets of non-U.S. subsidiaries are primarily invested in local currencies in order to satisfy regulatory requirements and to support local insurance operations regardless of currency fluctuations.

The principal currencies creating foreign exchange risk are the British pound sterling and the European Union euro. The Company's purchase of MBIA UK in 2017 increased its exposure to the British pound sterling. The Company cannot accurately predict the nature or extent of future exchange rate variability between these currencies or relative to the U.S. dollar. Foreign exchange rates are sensitive to factors beyond the Company's control. The pending separation of the U.K. from the EU may increase currency fluctuations in the next several years. See “Risks Related to the Financial, Credit and Financial Guaranty Markets - Brexit may adversely impact exposures insured by the Company and may also adversely impact the Company through currency exchange rates.”

The Company does not engage in active management, or hedging, of its foreign exchange rate risk. Therefore, fluctuation in exchange rates between these currenciesthe U.S. dollar and the U.S. dollarBritish pound sterling or the European Union euro could adversely impact the Company's financial position, results of operations and cash flows. See Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risk, Sensitivity of Investment Portfolio to Foreign Exchange Risk and Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risk, Sensitivity of Premiums Receivable to Foreign Exchange Risk.

The Company may be adversely impacted by the transition from LIBOR as a reference rate.

In 2017, the United Kingdom’s Financial Conduct Authority announced that after 2021 it would no longer compel banks to submit the rates required to calculate the LIBOR. This announcement indicates that the continuation of LIBOR on the current basis cannot and will not be guaranteed after 2021. Consequently, at this time, it is not possible to predict whether and to what extent banks will continue to provide submissions for the calculation of LIBOR. While regulators have suggested substitute rates, including the Secured Overnight Financing Rate, the impact of the discontinuance of LIBOR, if it occurs, will be contract-specific. Issuers of obligations the Company insures have obligations, assets and hedges that reference LIBOR, and some of the obligations the Company insures reference LIBOR. Some of the debt issued by the Company, as well as committed capital securities from which it benefits, also pay interest tied to LIBOR. See Part II, Item 8, Financial Statements and Supplementary Data, Note 16, Long-Term Debt and Credit Facilities. The Company cannot at this time predict the impact of the discontinuance of LIBOR, if it occurs, on every obligor and obligation the Company enhances.

The Company's international operations expose it to less predictable credit and legal risks.

The Company pursues new business opportunities in international markets. The underwriting of obligations of an issuer in a foreign country involves the same process as that for a domestic issuer, but additional risks must be addressed, such as the evaluation of foreign currency exchange rates, foreign business and legal issues, and the economic and political environment of the foreign country or countries in which an issuer does business. Changes in such factors could impede the Company's ability to insure, or increase the risk of loss from insuring, obligations in the countries in which it currently does business and limit its ability to pursue business opportunities in other countries.

The Company's investment portfolio may be adversely affected by credit, interest rate and other market changes.

The Company's operating results are affected, in part, by the performance of its investment portfolio which primarily consists primarily of fixed-income securities and short-term investments. As of December 31, 2016, the2018, fixed-maturity securities and short-term investments had a fair value of approximately $10.8 billion. Credit losses and changes in interest rates could have an adverse effect on itsthe Company's shareholders' equity and net income. Credit losses result in realized losses on the Company's investment portfolio, which reduce net income and shareholders' equity. Changes in interest rates can affect both shareholders' equity and investment income. For example, if interest rates decline, funds reinvested will earn less than expected, reducing the Company's future investment income compared to the amount it would earn if interest rates had not declined. However, the value of the Company's fixed-rate investments would generally increase if interest rates decreased, resulting in an unrealized gain on investments included in shareholders' equity. Conversely, if interest rates increase, the value of the fixed-rate investment portfolio will be reduced, resulting in unrealized losses that the Company is required to include in shareholders' equity as a change in accumulated other comprehensive income.income (OCI). Accordingly, interest rate increases could reduce the Company's shareholders' equity.

Interest rates are highly sensitive to many factors, including monetary policies, domestic and international economic and political conditions and other factors beyond the Company's control. The Company does not engage in active management, or hedging, of interest rate risk, and may not be able to mitigate interest rate sensitivity effectively.

The market value of the investment portfolio also may be adversely affected by general developments in the capital markets, including decreased market liquidity for investment assets, market perception of increased credit risk with respect to the types of securities held in the portfolio, downgrades of credit ratings of issuers of investment assets and/or foreign exchange movements impacting investment assets. In addition, the Company invests in securities insured by other financial guarantors, the market value of which may be affected by the rating instability of the relevant financial guarantor.

The Company also invests a portion of its excess capital in alternative investments, which also may be affected by credit, interest rate and other market changes as well as factors specific to those investments. See "Risks Related to the Company's Business - Alternative investments may not result in the benefits anticipated."

‘Brexit’
Brexit may adversely impact creditsexposures insured by the Company and may also adversely impact the Company through currency exchange rates.

OnAs described above in Part 1, Item 1, Business, Regulation, on June 23, 2016, a referendum was held in the U.K. in which a majority voted to exit the EU, known as “Brexit”. The U.K. government has indicated that it intends to formally serveserved notice to the European Council byon March 29, 2017 of its desire to withdraw in accordance with Article 50 of the Treaty on European Union. NegotiationsUnion, and there has been no approval by the U.K. parliament of any withdrawal agreement between the U.K.EU and the U.K. Failing such approval or the implementation of an agreed extension to the U.K.'s planned departure date, the it is currently expected that the U.K. will leave the EU will determineon March 29, 2019 under a No-Deal Brexit, leaving considerable uncertainty as to the futureongoing terms of the U.K’s relationship with the EU, including the terms of trade between the U.K. and the EU.EU, and a likely negative impact on all parties. Any resulting political, social and economic uncertainty and changes arising from Brexit, including a No-Deal Brexit if it occurs, may have a negative impact on the economies of the U.K. as well as non-U.K. EU and EEA countries, which may increase the probability of losses on obligations insured by the Company that are exposed to risks in the U.K. and non-U.K. EU and EEA countries. Given the lack of clarity on the ultimate post-Brexit relationship between the U.K. and the EU, the Company cannot fully determine what, if any, impact Brexit may have on its operations, both inside and outside the U.K.

Brexit, especially a No-Deal Brexit if it occurs, may also impact currency exchange rates. The Company reports its accounts in U.S. dollars, while some of its income, expenses and assets are denominated in other currencies, primarily the pound sterling and the euro. FromFor example, from December 31, 2015 to December 31, 2016, which period encompasses the Brexit vote, the value of pound sterling changeddropped from £0.68 per dollar to £0.81 per dollar, while the euro changeddropped from €0.83 per dollar to €0.95 per dollar. For the year ended 2016, the Company recognized losses of approximately $21 million in the consolidated statement of operations, net of tax, and approximately $32 million in OCI, net of tax, for foreign currency translation, that were primarily driven by the exchange rate fluctuations of the pound sterling. IfCurrency exchange rates may also move materially as the Company had owned AGLN during 2016, these impacts would have been greater.terms of Brexit become known.


Risks Related to the Company's CapitalSee also "Changes in applicable laws and Liquidity Requirements

Significant claim payments may reduce the Company's liquidity.

Claim payments reduce the Company's invested assets and result in reduced liquidity and net investment income, even if the Company is reimbursed in full over time and does not experience ultimate loss on a particular policy. Since the financial crisis, many of the claims paid by the Company were with respect to insured U.S. RMBS securities. More recently, there has been credit deterioration with respect to certain insured Puerto Rico credits. The Company had net par outstanding to general obligation bonds of the Commonwealth of Puerto Rico and various obligations of its related authorities and public corporations aggregating of $4.8 billion and $5.1 billion, respectively, as of December 31, 2016 and December 31, 2015, all of which was rated BIG under the Company’s rating methodology as of December 31, 2016. For a discussion of the Company's Puerto Rico risks and RMBS transactions, see Part II, Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure.

As of December 31, 2016, the Company had exposure of approximately $528 million to a long-term infrastructure project that was financed by bonds that mature prior to the expiration of the project concession. The Company expects the cash flows from the project to be sufficient to repay all of the debt over the life of the project concession, and also expects the debt to be refinanced in the market at or prior to its maturity. If the issuer is unable to refinance the debt due to market conditions, the Company may have to pay claims when the debt matures from 2018 to 2022, and then recover from cash flows produced by the project in the future. The Company generally projects that in most scenarios it will be fully reimbursed for such claim payments. However, the recovery of such amounts is uncertain and may take from 10 to 35 years, depending on the performance of the underlying collateral.

The Company plans for future claim payments. If the amount of future claim payments is significantly more than projected by the Company, however, the Company's ability to make other claim payments and its financial condition, financial strength ratings and business prospects could be adversely affected.

The Company may require additional capital from time to time, including from soft capital and liquidity credit facilities, which may not be available or may be available only on unfavorable terms.

The Company's capital requirements depend on many factors, primarily related to its in-force book of business and rating agency capital requirements. The Company needs liquid assets to make claim payments on its insured portfolio and to write new business. Failure to raise additional capital as needed may result in the Company being unable to write new business and may result in the ratings of the Company and its subsidiaries being downgraded by one or more ratings agency. The Company's access to external sources of financing, as well as the cost of such financing, is dependent on various factors, including the market supply of such financing, the Company's long-term debt ratings and insurance financial strength ratings and the perceptions of its financial strength and the financial strength of its insurance subsidiaries. The Company's debt ratings are in turn influenced by numerous factors, such as financial leverage, balance sheet strength, capital structure and earnings trends. If the Company's need for capital arises because of significant losses, the occurrence of these losses may make it more difficult for the Company to raise the necessary capital.

Future capital raises for equity or equity-linked securities could also result in dilution to the Company's shareholders. In addition, some securities that the Company could issue, such as preferred stock or securities issued by the Company's operating subsidiaries, may have rights, preferences and privileges that are senior to those of its common shares.

Financial guaranty insurers and reinsurers typically rely on providers of lines of credit, credit swap facilities and similar capital support mechanisms (often referred to as "soft capital") to supplement their existing capital base, or "hard capital." The ratings of soft capital providers directly affect the level of capital credit which the rating agencies give the Company when evaluating its financial strength. The Company currently maintains soft capital facilities with providers having ratings adequate to provide the Company's desired capital credit. For example, effective January 1, 2016, AGC, AGM and MAC entered into a $360 million aggregate excess of loss reinsurance facility with a number of reinsurers, that covers certain U.S. public finance credits insured or reinsured by those companies. (For additional information, see Part II, Item 8, Financial Statements and Supplementary Data, Note 13, Reinsurance and Other Monoline Exposures). However, no assurance can be given that the Company will be able to renew any existing soft capital facilities or that one or more of the rating agencies will not downgrade or withdraw the applicable ratings of such providers in the future. In addition, the Company may not be able to replace a downgraded soft capital provider with an acceptable replacement provider for a variety of reasons, including if an acceptable replacement provider is unwilling to provide the Company with soft capital commitments or if no adequately-rated institutions are actively providing soft capital facilities. Furthermore, the rating agencies may in the future change their methodology and no longer give credit for soft capital, which may necessitate the Company having to raise additional capital in order to maintain its ratings.

An increase in AGL's subsidiaries' leverage ratio may prevent them from writing new insurance.

Insurance regulatory authorities impose capital requirements on AGL's insurance subsidiaries. These capital requirements, which include leverage ratios and surplus requirements, may limit the amount of insurance that the subsidiaries may write. The insurance subsidiaries have several alternatives available to control their leverage ratios, including obtaining capital contributions from the Company, purchasing reinsurance or entering into other loss mitigation agreements, or reducing the amount of new business written. However, a material reduction in the statutory capital and surplus of a subsidiary, whetherregulations resulting from underwriting or investment losses, a change in regulatory capital requirements or otherwise, or a disproportionate increase in the amount of risk in force, could increase a subsidiary's leverage ratio. This in turn could require that subsidiary to obtain reinsurance for existing business (which may not be available, or may be available on terms that the Company considers unfavorable), or add to its capital base to maintain its financial strength ratings. Failure to maintain regulatory capital levels could limit that subsidiary's ability to write new business.

The Company's holding companies' ability to meet its obligations may be constrained.

Each of AGL, AGUS and AGMH is a holding company and, as such, has no direct operations of its own. None of the holding companies expects to have any significant operations or assets other than its ownership of the shares of its subsidiaries.

The insurance company subsidiaries’ ability to pay dividends and make other payments depends, among other things, upon their financial condition, results of operations, cash requirements, and compliance with rating agency requirements, and is also subject to restrictions contained in the insurance laws and related regulations of their states of domicile. Restrictions applicable to AGM, AGC and MAC, and to AG Re and AGRO, are described under the "Regulation, United States, State Dividend Limitations" and "Regulation, Bermuda, Restrictions on Dividends and Distributions" sections of “Item 1. Business.” Such dividends and permitted payments are expected to be the primary source of funds for the holding companies to meet ongoing cash requirements, including operating expenses, any future debt service payments and other expenses, and to pay dividends to their respective shareholders. Accordingly, if the insurance subsidiaries cannot pay sufficient dividends or make other permitted payments at the times or in the amounts that are required, that would have an adverse effect on the ability of AGL, AGUS and AGMH to satisfy their ongoing cash requirements and on their ability to pay dividends to shareholders.

If AGRO were to pay dividends to its U.S. holding company parent and that U.S. holding company were to pay dividends to its Bermudian parent AG Re, such dividends would be subject to U.S. withholding tax at a rate of 30%.

The ability of AGL and its subsidiaries to meet their liquidity needs may be limited.

Each of AGL, AGUS and AGMH requires liquidity, either in the form of cash or in the ability to easily sell investment assets for cash, in order to meet its payment obligations, including, without limitation, its operating expenses, interest on debt and dividends on common shares, and to make capital investments in operating subsidiaries. The Company's operating subsidiaries require substantial liquidity in order to meet their respective payment and/or collateral posting obligations, including under financial guaranty insurance policies, CDS contracts or reinsurance agreements. They also require liquidity to pay operating expenses, reinsurance premiums, dividends to AGUS or AGMH for debt service and dividends to the Company, as well as, where appropriate, to make capital investments in their own subsidiaries. The Company cannot give any assurance that the liquidity of AGL and its subsidiaries will not be adversely affected by adverse market conditions, changes in insurance regulatory law or changes in general economic conditions.

AGL anticipates that its liquidity needs will be met by the ability of its operating subsidiaries to pay dividends or to make other payments; external financings; investment income from its invested assets; and current cash and short-term investments. The Company expects that its subsidiaries' need for liquidity will be met by the operating cash flows of such subsidiaries; external financings; investment income from their invested assets; and proceeds derived from the sale of its investment portfolio, a significant portion of which is in the form of cash or short-term investments. All of these sources of liquidity are subject to market, regulatory or other factors that may impact the Company's liquidity position at any time. As discussed above, AGL's insurance subsidiaries are subject to regulatory and rating agency restrictions limiting their ability to declare and to pay dividends and make other payments to AGL. As further noted above, external financing may or may not be available to AGL or its subsidiaries in the future on satisfactory terms.

In addition, investment income at AGL and its subsidiaries may fluctuate based on interest rates, defaults by the issuers of the securities AGL or its subsidiaries hold in their respective investment portfolios, the performance of alternative investments, or other factors that the Company does not control. Also, the value of the Company's investments may be adversely affected by changes in interest rates, credit risk and capital market conditions and thereforeBrexit may adversely affect the Company" under Risks Related to GAAP and Applicable Law.

Risks Related to the Company's Business

The Company's financial guarantyinsurance products may subject it to significant risks from individual or correlated credits.exposures.

The Company is exposed to the risk that issuers of debt that it insures or other counterparties may default in their financial obligations, whether as a result of insolvency, lack of liquidity, operational failure or other reasons. Similarly, the Company could be exposed to corporate credit risk if a corporation's securities are contained in a portfolio of collateralized debt obligations (CDOs) it insures, or if the corporation or financial institution is the originator or servicer of loans, mortgages or other assets backing structured securities that the Company has insured.

In addition, because the Company insures or reinsures municipal bonds, it canmay have significant exposures to single municipal risks; see Part II, Item 7, Management's Discussion and Analysis, Insured Portfolio, for a list of the Company's largest ten municipal risks by revenue source. While the Company's risk of a complete loss, where it would have to pay the entire principal amount of an issue of bonds and interest thereon with no recovery, is generally lower for municipal bonds, than for corporate bonds as most municipal bondsof which are backed by tax or other revenues, than for corporate bonds, there can be no assurance that a single default by a municipality would not have a material adverse effect on itsthe Company's results of operations or financial condition.

The Company's ultimate exposure to a single namerisk may exceed its underwriting guidelines (caused by, for example, acquisitions, reassumptions, or amortization of the portfolio faster than the single risk), and an event with respect to a single namerisk may cause a significant loss. The Company seeks to reduce this risk by managing exposure to large single risks, as well as concentrations of correlated risks, through tracking its aggregate exposure to single namesrisks in its various lines of business and establishing underwriting criteria to manage risk aggregations. It has also in the past obtained third party reinsurance for such exposure. The Company may insure and has insured individual public finance and asset-backed risks well in excess of $1 billion. Should the Company's risk assessments prove inaccurate and should the applicable limits prove inadequate, the Company could be exposed to larger than anticipated losses, and could be required by the rating agencies to hold additional capital against insured exposures whether or not downgraded by the rating agencies.

The Company is exposed to correlation risk across the various assets the Company insures. During periods of strong macroeconomic performance, stress in an individual transaction generally occurs for idiosyncratic reasons or as a result of issues in a single asset class or for idiosyncratic reasons.(so impacting only transactions in that sector). During a broad economic downturn, a wider range of the Company's insuredinsurance portfolio could be exposed to stress at the same time. This stress may manifest itself in ratings downgrades, which may require more capital, or in actual losses.losses, or both. In addition, while the CompanyCompany's portfolio has

experienced many catastrophic events in the past without material loss, unexpected catastrophic events may have a material adverse effect upon the Company's insured portfolio and/or its investment portfolios. For example, Hurricane Maria negatively impacted the Company’s exposure to Puerto Rico and its related authorities and public corporations. See “Risks Related to the Financial, Credit and Financial Guaranty Markets - Claim payments on obligations of the Commonwealth of Puerto Rico insured by the Company in excess of those expected by the Company could have a negative effect on the Company's liquidity and results of operations.”

Some of the Company's direct financial guaranty products may be riskier than traditional financial guaranty insurance.

As of December 31, 20162018 and 2015, 6% and 7%, respectively,2017, 2% of the Company's financial guaranty direct exposures were originally executed as credit derivatives. Traditional financial guaranty insurance provides an unconditional and irrevocable guaranty that protects the holder of a municipal finance or structured finance obligation against non-payment of principal and interest, while credit derivatives provide protection from the occurrence of specified credit events, including non-payment of principal and interest. In general, the Company structures credit derivative transactions such that circumstances giving rise to its obligation to make payments are similar to thatthose for financial guaranty policies and generally occur when issuers fail to make payments on the underlying reference obligations. The tenor of credit derivatives exposures, like exposure under financial guaranty insurance policies, is also generally for as long as the reference obligation remains outstanding.

Nonetheless, credit derivative transactions are governed by International Swaps and Derivatives Association, Inc. (ISDA) documentation and operate differently from financial guaranty insurance policies. For example, the Company's control rights with respect to a reference obligation under a credit derivative may be more limited than when it issues a financial guaranty insurance policy on a direct primary basis. In addition, a credit derivative may be terminated for a breach of the ISDA documentation or other specific events, unlike financial guaranty insurance policies. In addition, under a limited number of credit derivative contracts, the Company may be required to post eligible securities as collateral, generally cash or U.S. government or agency securities, under specified circumstances. The need to post collateral under many of these transactions is subject to caps that the Company has negotiated with its counterparties, but there are some transactions as to which the Company could be required to post collateral without such a cap based on movements in the mark-to-market valuation of the underlying exposure in excess of contractual thresholds. See Part II, Item 8, Financial Statements and Supplementary Data, Note 8, Contracts Accounted for as Credit Derivatives, Rating Sensitivities of Credit Derivatives Contracts.


Further downgrades of one or more of the Company's reinsurers could reduce the Company's capital adequacy and return on equity. The impairment of other financial institutions also could adversely affect the Company.

At December 31, 2016, the Company had ceded approximately 4% of its principal amount of insurance outstanding to third party reinsurers. In evaluating the credits insured by the Company, securities rating agencies allow capital charge "credit" for reinsurance based on the reinsurers' ratings. In recent years, a number of the Company's reinsurers were downgraded by one or more rating agencies, resulting in decreases in the credit allowed for reinsurance and in the financial benefits of using reinsurance under existing rating agency capital adequacy models. Many of the Company's reinsurers have already been downgraded to single-A or below by one or more rating agencies. The Company could be required to raise additional capital to replace the lost reinsurance credit in order to satisfy rating agency and regulatory capital adequacy and single risk requirements. The rating agencies' reduction in credit for reinsurance could also ultimately reduce the Company's return on equity to the extent that ceding commissions paid to the Company by the reinsurers were not adequately increased to compensate for the effect of any additional capital required. In addition, downgraded reinsurers may default on amounts due to the Company and such reinsurer obligations may not be adequately collateralized, resulting in additional losses to the Company and a reduction in its shareholders' equity and net income.

The Company also has exposure to counterparties in various industries, including banks, hedge funds and other investment vehicles in its insured transactions. Many of these transactions expose the Company to credit risk in the event its counterparty fails to perform its obligations.

Acquisitions may not result in the benefits anticipated and may subject the Company to non-monetary consequences.

                From time to time the Company evaluates financial guaranty portfolio and company acquisition opportunities and conducts diligence activities with respect to transactions with other financial guarantors and financial services companies. For example, during 2015 the Company acquired Radian Asset and in 2016 the Company acquired CIFG,CIFGNA, and in each case merged it with and into AGC, with AGC as the surviving company of the merger. In January 2017, the Company acquired MBIA UK. AcquiringUK, and on June 1, 2018, the Company closed a transaction with SGI under which AGC assumed, generally on a 100% quota share basis, substantially all of SGI’s insured portfolio and AGM reassumed a book of business previously ceded to SGI by AGM. These acquisitions as well as any future acquisitions of other financial guaranty portfolios or companies or other financial services companies may involve some or all of the various risks commonly associated with acquisitions, including, among other things: (a) failure to adequately identify and value potential exposures and liabilities of the target portfolio or entity; (b) difficulty in estimating the value of the target portfolio or entity; (c) potential diversion of management’s time and attention; (d) exposure to asset quality issues of the target entity; and (e) difficulty and expense of integrating the operations, systems and personnel of the target entity.entity; and (f) concentration of exposures, including exposures which may exceed single risk limits, due to the addition of the target portfolio. Such acquisitions may also have unintended consequences on ratings assigned by the rating agencies to the Company or its subsidiaries (see “-“— Risks Related to the Company’s Financial Strength and Financial Enhancement Ratings”) or on the applicability of laws and regulations to the Company’s existing businesses. These or other factors may cause any past or future acquisitions of financial guaranty portfolios or companies or other financial services companies not to result in the benefits to the Company anticipated when the acquisition was agreed.

Past or future acquisitions may also subject the Company to non-monetary consequences that may or may not have been anticipated or fully mitigated at the time of the acquisition. For example, in November 2006, AGMH received a subpoena from the Antitrust Division of the Department of Justice issued in connection with an ongoing criminal investigation of bid rigging of awards of municipal GICs and other municipal derivatives. AGMH responded to the subpoena and has had limited contact with the DOJ on the matter since late 2011. Although the subpoena related to AGMH's former Financial Products Business, which the Company did not acquire, it was issued to AGMH, which the Company did acquire.

Alternative investments may not result in the benefits anticipated.

From time to time in order to deploy a portion of the Company's excess capital the Company may invest in business opportunities that complement the Company's financial guaranty business, are in line with its risk profile and benefit from its core competencies. The alternative investments group has been investigating a number of such opportunities, including, among others, both controlling and non-controlling investments in investment managers. For example, in February 2017 the Company agreed to purchase up to $100 million of limited partnership interests in a fund that invests in the equity of private equity managers. In September 2017, the Company acquired a minority interest in Wasmer, Schroeder & Company LLC, an independent investment advisory firm specializing in SMAs. In February 2018, the Company acquired a minority interest in the holding company of Rubicon Infrastructure Advisors, a full-service investment firm based in Dublin that provides investment banking services within the global infrastructure sector. The Company continues to investigate additional opportunities. opportunities to make alternative investments, including, among others, both controlling and non-controlling investments in investment managers, but there can be no assurance if or when the Company will find suitable opportunities on appropriate terms.

Alternative investments may be riskier than many of the other investments the Company makes, and may not result in the benefits anticipated at the time of the investment. In addition, although the Company uses what it believes to be excess capital to make alternative investments, measures of required capital can fluctuate and such investments may not be given much, or any, value under the various rating agency, regulatory and internal capital models to which the Company is subject. Also, alternative investments may be less liquid than most of the Company's other investments and so may be difficult to convert to cash or investments that do receive credit under the capital models to which the Company is subject. See "Risks Related to the Company's Capital and Liquidity Requirements -- The ability of AGL and its subsidiaries to meet their liquidity needs may be limited."


The Company is dependent on key executives and the loss of any of these executives, or its inability to retain other key personnel, could adversely affect its business.

The Company's success substantially depends upon its ability to attract and retain qualified employees and upon the ability of its senior management and other key employees to implement its business strategy. The Company believes there are only a limited number of available qualified executives in the business lines in which the Company competes. The Company relies substantially upon the services of Dominic J. Frederico, President and Chief Executive Officer, and other executives. Although the Company has designed its executive compensation with the goal of retaining and creating incentives for its executive officers, the Company may not be successful in retaining their services. The loss of the services of any of these individuals or other key members of the Company's management team could adversely affect the implementation of its business strategy.

The Company is dependent on its information technology and that of certain third parties, and a cyber-attack,cyberattack, security breach or failure in such systems could adversely affect the Company’s business.

The Company relies upon information technology and systems, including technology and systems provided by or interfacing with those of third parties, to support a variety of its business processes and activities.  In addition, the Company has collected and stored confidential information including, in connection with certain loss mitigation and due diligence activities related to its structured finance business, personally identifiable information.  While the Company does not believe that the financial guaranty industry is as inherently prone to cyber-attackscyberattacks as industries relating to, for example, payment card processing, banking, critical infrastructure or defense contracting, the Company’s data systems and those of third parties on which it relies are still vulnerable to security breaches due to cyber-attacks,cyberattacks, viruses, malware, ransomware, hackers and other external hazards, as well as inadvertent errors, equipment and system failures, and employee misconduct.  Problems in or security breaches of these systems could, for example, result in lost business, reputational harm, the disclosure or misuse of confidential or proprietary information, incorrect reporting, inaccurate loss projections, legal costs and regulatory penalties. 

The Company’s business operations rely on the continuous availability of its computer systems as well as those of certain third parties.  In addition to disruptions caused by cyber-attackscyberattacks or other data breaches, such systems may be adversely affected by natural and man-made catastrophes.  The Company’s failure to maintain business continuity in the wake of such events, particularly if there were an interruption for an extended period, could prevent the timely completion of critical processes across its operations, including, for example, claims processing, treasury and investment operations and payroll.  These failures could result in additional costs, loss of business, fines and litigation.

The Company and its subsidiaries are subject to numerous laws and regulations of a number of jurisdictions regarding its information systems, particularly with regard to personally identifiable information. The Company's failure to comply with these requirements, even absent a security breach, could result in penalties, reputational harm or difficulty in obtaining desired consents from regulatory authorities.

The Board of Directors oversees the risk management process, including cybersecurity risks, and engages with management on risk management issues, including cybersecurity issues. The Audit Committee of the Board of Directors has specific responsibility for overseeing information technology matters, including cybersecurity risk, and the Risk Oversight Committee of the Board of Directors addresses cybersecurity matters as part of its enterprise risk management responsibilities.


Risks Related to the Company's Financial Strength and Financial Enhancement Ratings

A downgrade of the financial strength or financial enhancement ratings of any of the Company's insurance and reinsurance subsidiaries would adversely affect its business and prospects and, consequently, its results of operations and financial condition.

The financial strength and financial enhancement ratings assigned by S&P, Moody’s, KBRA and Best to each of AGL's insurance and reinsurance subsidiaries represent such rating agencies' opinions of the insurer's financial strength and ability to meet ongoing obligations to policyholders and cedants in accordance with the terms of the financial guaranties it has issued or the reinsurance agreements it has executed. The ratings also reflect qualitative factors, such as the rating agencies' opinion of an insurer's business strategy and franchise value, the anticipated future demand for its product, the composition of its insured portfolio, and its capital adequacy, profitability and financial flexibility. Issuers, investors, underwriters, ceding companies and others consider the Company's financial strength or financial enhancement ratings an important factor when deciding whether or not to utilize a financial guaranty or purchase reinsurance from one of the Company's insurance or reinsurance subsidiaries. A downgrade by a rating agency of the financial strength or financial enhancement ratings of one or more of AGL's subsidiaries could impair the Company's financial condition, results of operation, liquidity, business prospects or other aspects of the Company's business.

The ratings assigned by the rating agencies that publish financial strength or financial enhancement ratings on AGL's insurance subsidiaries are subject to review and may be lowered by a rating agency as a result of a number of factors, including, but not limited to, the rating agency's revised stress loss estimates for the Company's insurance portfolio, adverse developments in the Company's or the subsidiary's financial conditions or results of operations due to underwriting or investment losses or other factors, changes in the rating agency's outlook for the financial guaranty industry or in the markets in which the Company operates, or a revision in the rating agency's capital model or rating methodology. Their reviews can occur at any time and without notice to the Company and could result in a decision to downgrade, revise or withdraw the financial strength or financial enhancement ratings of AGL's insurance and reinsurance subsidiaries. For example, while all of the rating agencies that rate AGL subsidiaries with exposure to Puerto Rico have indicated that their evaluations of such AGL subsidiaries already take into account stress scenarios related to developments in Puerto Rico, actual developments in Puerto Rico beyond what a rating agency previously considered could cause that rating agency to review its ratings of such AGL subsidiaries.

The Company periodically assesses the value of each rating assigned to each of its companies, and may as a result of such assessment request that a rating agency add or drop a rating from certain of its companies. For example, the KBRA ratings were first assigned to MAC in 2013, to AGM in 2014, to AGC in 2016 and to AGE in 2018, and the Best rating was first assigned to AGRO in 2015, while a Moody’s rating was never requested for MAC and was dropped from AG Re and AGRO in 2015. In January 2017, AGC requested that Moody’s withdraw its financial strength rating of AGC, but Moody’s denied that request and still rates AGC.

The insurance subsidiaries' financial strength ratings are an important competitive factor in the financial guaranty insurance and reinsurance markets. If the financial strength or financial enhancement ratings of one or more of the Company's insurance subsidiaries were reduced below current levels, the Company expects that would reduce the number of transactions that would benefit from the Company's insurance; consequently, a downgrade by rating agencies could harm the Company's new business production, results of operations and financial condition.

In addition, a downgrade may have a negative impact on the Company in respect of transactions that it has insured or reinsurance that it has assumed. For example, a downgrade of one of the Company's insurance subsidiaries may result in increased claims under financial guaranties such subsidiary has issued. Under variable rate demand obligations insured by AGM, downgrades past rating levels specified in the transaction documents could result in the municipal obligor paying a higher rate of interest and in such obligations amortizing on a more accelerated basis than expected when the obligations originally were issued; if the municipal obligor is unable to make such interest or principal payments, AGM may receive a claim under its financial guaranty. Under interest rate swaps insured by AGM, downgrades past specified rating levels could entitle the municipal obligor's swap counterparty to terminate the swap; if the municipal obligor owed a termination payment as a result and were unable to make such payment, AGM may receive a claim if its financial guaranty guaranteed such termination payment. For more information about increased claim payments the Company may potentially make, see Part II, Item 8, Financial Statements and Supplementary Data, Note 6, Contracts Accounted for as Insurance, Ratings Impact on Financial Guaranty Business. In certain other transactions, beneficiaries of financial guaranties issued by the Company's insurance subsidiaries may have the right to cancel the credit protection offered by the Company, which would result in the loss of future premium earnings and the reversal of any fair value gains recorded by the Company. In addition, a downgrade of AG Re, AGC or AGRO could result in certain ceding companies recapturing business that they had ceded to these reinsurers. See "The downgrade of the financial strength ratings of AG Re, AGC or AGRO would give certain reinsurance counterparties the right to

recapture certain ceded business, which would lead to a reduction in the Company's unearned premium reserve and related earnings" below.

Furthermore, if the financial strength ratings of AGE were downgraded, AGM may be required to contribute additional capital to AGE pursuant to the terms of the support arrangement for AGE, as described in "Item 1. Business, Regulation, United Kingdom, Material Contracts."

The downgrade of the financial strength ratings of AG Re, AGC or AGRO would give certain reinsurance counterparties the right to recapture certain ceded business, which would lead to a reduction in the Company's unearned premium reserve and related earnings.

The downgrade of the financial strength ratings of AG Re, AGC or AGRO gives certain reinsurance counterparties the right to recapture certain ceded business, which would involve payments by the Company and lead to a reduction in the Company's unearned premium reserve and related earnings. As of December 31, 2018, if each third party company ceding business to AG Re, AGC and/or AGRO had a right to recapture such business, and chose to exercise such right, the aggregate amounts that AG Re, AGC and AGRO could be required to pay to all such companies would be approximately $42 million, $326 million and $10 million, respectively.

Actions taken by the rating agencies with respect to capital models and rating methodology of the Company's business or changes in capital charges or downgrades of transactions within its insured portfolio may adversely affect its ratings, business prospects, results of operations and financial condition.

The rating agencies from time to time have evaluated the Company's capital adequacy under a variety of scenarios and assumptions. The rating agencies do not always supply clear guidance on their approach to assessing the Company's capital adequacy and the Company may disagree with the rating agencies' approach and assumptions. For example, S&P assesses each individual exposure (including potential new exposures) insured by the Company based on a variety of factors, including the nature of the exposure, the nature of the support or credit enhancement for the exposure, its tenor, and its expected and actual performance. This assessment determines the amount of capital the Company is required to maintain against that exposure to maintain its financial strength ratings under S&P's capital adequacy model. Sometimes the rating agencies consider the amount of additional capital that could be required for certain risks or sectors under certain stress scenarios based on their views of developments in the market, as each have done recently with respect to the Company's exposures to Puerto Rico. Factors influencing the rating agencies are beyond management's control and not always known to the Company. In the event of an actual or perceived deterioration in creditworthiness, or a change in a rating agency's capital model or rating methodology, that rating agency may require the Company to increase the amount of capital allocated to support the affected exposures, regardless of whether losses actually occur, or against potential new business. Significant reductions in the rating agencies' assessments of exposures in the Company's insured portfolio can produce significant increases in the amount of capital required for the Company to maintain its financial strength ratings under the rating agencies' capital adequacy models, which may require the Company to seek additional capital. The amount of such capital required may be substantial, and may not be available to the Company on favorable terms and conditions or at all. Accordingly, the Company cannot ensure that it will seek or be able to raise additional capital. The failure to raise additional required capital could result in a downgrade of the Company's ratings and thus have an adverse impact on its business, results of operations and financial condition. See "Risks Related to the Company's Capital and Liquidity Requirements—The Company may require additional capital from time to time, including from soft capital and liquidity credit facilities, which may not be available or may be available only on unfavorable terms."

Risks Related to the Company's Capital and Liquidity Requirements

Significant claim payments may reduce the Company's liquidity.

Claim payments reduce the Company's invested assets and result in reduced liquidity and net investment income, even if the Company is reimbursed in full over time and does not experience ultimate loss on a particular policy. Since the financial crisis in 2008, many of the claims paid by the Company were with respect to insured U.S. RMBS securities. More recently, there has been credit deterioration with respect to certain insured Puerto Rico exposures, and the Company has paid material claims with respect to a number of those exposures. The Company had net par outstanding to general obligation bonds of the Commonwealth of Puerto Rico and various obligations of its related authorities and public corporations aggregating $4.8 billion and $5.0 billion, respectively, as of December 31, 2018 and December 31, 2017, all of which was rated BIG under the Company’s rating methodology. For a discussion of the Company's Puerto Rico risks, see Part II, Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure.


The Company plans for future claim payments. If the amount of future claim payments is significantly more than that projected by the Company, however, the Company's ability to make other claim payments and its financial condition, financial strength ratings and business prospects could be adversely affected.

The Company may require additional capital from time to time, including from soft capital and liquidity credit facilities, which may not be available or may be available only on unfavorable terms.

The Company's capital requirements depend on many factors, primarily related to its in-force book of business and rating agency capital requirements. Failure to raise additional capital if and as needed may result in the Company being unable to write new business and may result in the ratings of the Company and its subsidiaries being downgraded by one or more rating agency. The Company's access to external sources of financing, as well as the cost of such financing, is dependent on various factors, including the market supply of such financing, the Company's long-term debt ratings and insurance financial strength ratings and the perceptions of its financial strength and the financial strength of its insurance subsidiaries. The Company's debt ratings are in turn influenced by numerous factors, such as financial leverage, balance sheet strength, capital structure and earnings trends. If the Company's need for capital arises because of significant losses, the occurrence of these losses may make it more difficult for the Company to raise the necessary capital.

Future capital raises for equity or equity-linked securities could also result in dilution to the Company's shareholders. In addition, some securities that the Company could issue, such as preferred stock or securities issued by the Company's operating subsidiaries, may have rights, preferences and privileges that are senior to those of its common shares.

Financial guaranty insurers and reinsurers typically rely on providers of lines of credit, excess of loss reinsurance facilities and similar capital support mechanisms (often referred to as "soft capital") to supplement their existing capital base, or "hard capital." The ratings of soft capital providers directly affect the level of capital credit which the rating agencies give the Company when evaluating its financial strength. The Company currently maintains soft capital facilities with providers having ratings adequate to provide the Company's desired capital credit. For example, effective January 1, 2018, AGC, AGM and MAC entered into a $400 million aggregate excess of loss reinsurance facility of which $180 million was placed with an unaffiliated reinsurer, that covers certain U.S. public finance exposures insured or reinsured by those companies. (For additional information, see Part II, Item 8, Financial Statements and Supplementary Data, Note 13, Reinsurance). However, no assurance can be given that the Company will be able to renew any existing soft capital facilities or that one or more of the rating agencies will not downgrade or withdraw the applicable ratings of such providers in the future. In addition, the Company may not be able to replace a downgraded soft capital provider with an acceptable replacement provider for a variety of reasons, including the unwillingness of an acceptable replacement provider to provide the Company with soft capital commitments or the lack of adequately-rated institutions that are actively providing soft capital facilities. Furthermore, the rating agencies may in the future change their methodology and no longer give credit for soft capital, which may necessitate the Company having to raise additional capital in order to maintain its ratings.

An increase in AGL's subsidiaries' leverage ratio may prevent them from writing new insurance.

Insurance regulatory authorities impose capital requirements on AGL's insurance subsidiaries. These capital requirements, which include leverage ratios and surplus requirements, may limit the amount of insurance that the subsidiaries may write. The insurance subsidiaries have several alternatives available to control their leverage ratios, including obtaining capital contributions from affiliates, purchasing reinsurance or entering into other loss mitigation agreements, or reducing the amount of new business written. However, a material reduction in the statutory capital and surplus of a subsidiary, whether resulting from underwriting or investment losses, a change in regulatory capital requirements or otherwise, or a disproportionate increase in the amount of risk in force, could increase a subsidiary's leverage ratio. This in turn could require that subsidiary to obtain reinsurance for existing business (which may not be available, or may be available on terms that the Company considers unfavorable), or add to its capital base to maintain its financial strength ratings. Failure to maintain regulatory capital levels could limit that subsidiary's ability to write new business.

The Company's holding companies' ability to meet their obligations may be constrained.

Each of AGL, AGUS and AGMH is a holding company and, as such, has no direct operations of its own. None of the holding companies expects to have any significant operations or assets other than its ownership of the shares of its subsidiaries.


The insurance company subsidiaries’ ability to pay dividends and make other payments depends, among other things, upon their financial condition, results of operations, cash requirements, and compliance with rating agency requirements, and is also subject to restrictions contained in the insurance laws and related regulations of their states of domicile. Restrictions applicable to AGM, AGC and MAC, and to AG Re and AGRO, are described under the "Regulation, United States, State Dividend Limitations" and "Regulation, Bermuda, Restrictions on Dividends and Distributions" sections of “Item 1. Business.” Such dividends and permitted payments are currently expected to be the primary source of funds for the holding companies to meet ongoing cash requirements, including operating expenses, any future debt service payments and other expenses, and to pay dividends to their respective shareholders. Accordingly, if the insurance subsidiaries cannot pay sufficient dividends or make other permitted payments at the times or in the amounts that are required, that would have an adverse effect on the ability of AGL, AGUS and AGMH to satisfy their ongoing cash requirements and on their ability to pay dividends to shareholders.

If AGRO were to pay dividends to its U.S. holding company parent and that U.S. holding company were to pay dividends to its Bermudian parent AG Re, such dividends would be subject to U.S. withholding tax at a rate of 30%.

The ability of AGL and its subsidiaries to meet their liquidity needs may be limited.

Each of AGL, AGUS and AGMH requires liquidity, either in the form of cash or in the ability to easily sell investment assets for cash, in order to meet its payment obligations, including, without limitation, its operating expenses, interest on debt and dividends on common shares, and to make capital investments in operating subsidiaries. The Company's operating subsidiaries require substantial liquidity in order to meet their respective payment and/or collateral posting obligations, including under financial guaranty insurance policies, CDS contracts or reinsurance agreements. They also require liquidity to pay operating expenses, reinsurance premiums, dividends to AGUS or AGMH for debt service and dividends to AGL, as well as, where appropriate, to make capital investments in their own subsidiaries. In addition, the Company may require substantial liquidity to fund any future acquisitions. The Company cannot give any assurance that the liquidity of AGL and its subsidiaries will not be adversely affected by adverse market conditions, changes in insurance regulatory law or changes in general economic conditions.

AGL anticipates that its liquidity needs will be met by the ability of its operating subsidiaries to pay dividends or to make other payments; external financings; investment income from its invested assets; and current cash and short-term investments. The Company expects that its subsidiaries' need for liquidity will be met by the operating cash flows of such subsidiaries; external financings; investment income from their invested assets; and proceeds derived from the sale of their investment portfolios, significant portions of which are in the form of cash or short-term investments. All of these sources of liquidity are subject to market, regulatory or other factors that may impact the Company's liquidity position at any time. As discussed above, AGL's insurance subsidiaries are subject to regulatory and rating agency restrictions limiting their ability to declare and to pay dividends and make other payments to AGL. As further noted above, external financing may or may not be available to AGL or its subsidiaries in the future on satisfactory terms.

In addition, investment income at AGL and its subsidiaries may fluctuate based on interest rates, defaults by the issuers of the securities AGL or its subsidiaries hold in their respective investment portfolios, the performance of alternative investments, or other factors that the Company does not control. Also, the value of the Company's investments may be adversely affected by changes in interest rates, credit risk and capital market conditions and therefore may adversely affect the Company's potential ability to sell investments quickly and the price which the Company might receive for those investments. Alternative investments may be particularly difficult to sell at adequate prices or at all.

Risks Related to Taxation

Changes in U.S. tax laws could reduce the demand or profitability of financial guaranty insurance, or negatively impact the Company's investment portfolio.

The Tax Act included provisions that could result in a reduction of supply, such as the termination of advance refunding bonds. Any such lower volume of municipal obligations could impact the amount of such obligations that could benefit from insurance. The supply of municipal bonds in 2018 was below that in 2017, possibly due at least in part to the impact of the Tax Act. In addition, the reduction of the U.S. corporate income tax rate to 21% could make municipal obligations less attractive to certain institutional investors such as banks and property and casualty insurance companies, resulting in lower demand for municipal obligations.

Further, future changes in U.S. federal, state or local laws that materially adversely affect the tax treatment of municipal securities or the market for those securities, or other changes negatively affecting the municipal securities market, may lower volume and demand for municipal obligations and also may adversely impact the Company's investment portfolio, a

significant portion of which is invested in tax-exempt instruments. These adverse changes may adversely affect the value of the Company's tax-exempt portfolio, or its liquidity.

Certain of the Company's non-U.S. subsidiaries may be subject to U.S. tax.

The Company manages its business so that AGL and its non-U.S. subsidiaries (other than AGRO) operate in such a manner that none of them should be subject to U.S. federal tax (other than U.S. excise tax on insurance and reinsurance premium income attributable to insuring or reinsuring U.S. risks, and U.S. withholding tax on certain U.S. source investment income). However, because there is considerable uncertainty as to the activities which constitute being engaged in a trade or business within the U.S., the Company cannot be certain that the IRS will not contend successfully that AGL or any of its non-U.S. subsidiaries (other than AGRO) is/are engaged in a trade or business in the U.S. If AGL and its non-U.S. subsidiaries (other than AGRO) were considered to be engaged in a trade or business in the U.S., each such company could be subject to U.S. corporate income and branch profits taxes on the portion of its earnings effectively connected to such U.S. business.

AGL, AG Re and AGRO may become subject to taxes in Bermuda after March 2035, which may have a material adverse effect on the Company's results of operations and on an investment in the Company.

The Bermuda Minister of Finance, under Bermuda's Exempted Undertakings Tax Protection Act 1966, as amended, has given AGL, AG Re and AGRO an assurance that if any legislation is enacted in Bermuda that would impose tax computed on profits or income, or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then subject to certain limitations the imposition of any such tax will not be applicable to AGL, AG Re or AGRO, or any of AGL's or its subsidiaries' operations, shares, debentures or other obligations until March 31, 2035. Given the limited duration of the Minister of Finance's assurance, the Company cannot be certain that it will not be subject to Bermuda tax after March 31, 2035.

U.S. Persons who hold 10% or more of AGL's shares directly or through non-U.S. entities may be subject to taxation under the U.S. controlled non-U.S. corporation rules.

Each 10% U.S. shareholder of a non-U.S. corporation that is a CFC at any time during a taxable year that owns shares in the non-U.S. corporation directly or indirectly through non-U.S. entities on the last day of the non-U.S. corporation's taxable year on which it is a CFC, must include in its gross income for U.S. federal income tax purposes its pro rata share of the CFC's "subpart F income," even if the subpart F income is not distributed. In addition, upon a sale of shares of a CFC, 10% U.S. shareholders may be subject to U.S. federal income tax on a portion of their gain at ordinary income rates.

The Company believes that because of the dispersion of the share ownership in AGL, no U.S. Person who owns AGL's shares directly or indirectly through non-U.S. entities should be treated as a 10% U.S. shareholder of AGL or of any of its non-U.S. subsidiaries. However, AGL’s shares may not be as widely dispersed as the Company believes due to, for example, the application of certain ownership attribution rules, and no assurance may be given that a U.S. Person who owns the Company's shares will not be characterized as a 10% U.S. shareholder, in which case such U.S. Person may be subject to taxation under U.S. CFC rules.

U.S. Persons who hold shares may be subject to U.S. income taxation at ordinary income rates on their proportionate share of the Company's related person insurance income.

If the following conditions are true, then a U.S. Person who owns AGL's shares (directly or indirectly through non-U.S. entities) on the last day of the taxable year would be required to include in its income for U.S. federal income tax purposes such person's pro rata share of the RPII of such Foreign Insurance Subsidiary (as defined above) for the entire taxable year, determined as if such RPII were distributed proportionately only to U.S. Persons at that date, regardless of whether such income is distributed:

the Company is 25% or more owned directly, indirectly through non-U.S. entities or by attribution by U.S. Persons;

the gross RPII of AG Re or any other AGL non-U.S. subsidiary engaged in the insurance business that has not made an election under section 953(d) of the Code to be treated as a U.S. corporation for all U.S. tax purposes or are CFCs owned directly or indirectly by AGUS (each, with AG Re, a Foreign Insurance Subsidiary) equals or exceeds 20% of such Foreign Insurance Subsidiary's gross insurance income in any taxable year; and


direct or indirect insureds (and persons related to such insureds) own (or are treated as owning directly or indirectly through entities) 20% or more of the voting power or value of the Company's shares.

In addition, any RPII that is includible in the income of a U.S. tax-exempt organization may be treated as unrelated business taxable income.

The amount of RPII earned by a Foreign Insurance Subsidiary (generally, premium and related investment income from the direct or indirect insurance or reinsurance of any direct or indirect U.S. holder of shares or any person related to such holder) will depend on a number of factors, including the geographic distribution of a Foreign Insurance Subsidiary's business and the identity of persons directly or indirectly insured or reinsured by a Foreign Insurance Subsidiary. The Company believes that each of its Foreign Insurance Subsidiaries either should not in the foreseeable future have RPII income which equals or exceeds 20% of its gross insurance income or have direct or indirect insureds, as provided for by RPII rules, that directly or indirectly own 20% or more of either the voting power or value of AGL's shares. However, the Company cannot be certain that this will be the case because some of the factors which determine the extent of RPII may be beyond its control.

U.S. Persons who dispose of AGL's shares may be subject to U.S. income taxation at dividend tax rates on a portion of their gain, if any.

The meaning of the RPII provisions and the application thereof to AGL and its Foreign Insurance Subsidiaries is uncertain. The RPII rules in conjunction with section 1248 of the Code provide that if a U.S. Person disposes of shares in a non-U.S. insurance corporation in which U.S. Persons own (directly, indirectly, through non-U.S. entities or by attribution) 25% or more of the shares (even if the amount of gross RPII is less than 20% of the corporation's gross insurance income and the ownership of its shares by direct or indirect insureds and related persons is less than the 20% threshold), any gain from the disposition will generally be treated as dividend income to the extent of the holder's share of the corporation's undistributed earnings and profits that were accumulated during the period that the holder owned the shares. This provision applies whether or not such earnings and profits are attributable to RPII. In addition, such a holder will be required to comply with certain reporting requirements, regardless of the amount of shares owned by the holder.

In the case of AGL's shares, these RPII rules should not apply to dispositions of shares because AGL is not itself directly engaged in the insurance business. However, the RPII provisions have never been interpreted by the courts or the U.S. Treasury Department in final regulations, and regulations interpreting the RPII provisions of the Code exist only in proposed form. It is not certain whether these regulations will be adopted in their proposed form, what changes or clarifications might ultimately be made thereto, or whether any such changes, as well as any interpretation or application of the RPII rules by the IRS, the courts, or otherwise, might have retroactive effect. The U.S. Treasury Department has authority to impose, among other things, additional reporting requirements with respect to RPII.

U.S. Persons who hold common shares will be subject to adverse tax consequences if AGL is considered to be a "passive foreign investment company" for U.S. federal income tax purposes.

If AGL is considered a PFIC for U.S. federal income tax purposes, a U.S. Person who owns any shares of AGL will be subject to adverse tax consequences that could materially adversely affect its investment, including subjecting the investor to both a greater tax liability than might otherwise apply and an interest charge. The Company believes that AGL was not a PFIC for U.S. federal income tax purposes for taxable years through 2018 and, based on the application of certain PFIC look-through rules and the Company's plan of operations for the current and future years, should not be a PFIC in the future. However, as discussed above, the Tax Act limits the insurance income exception to a non-U.S. insurance company that is a qualifying insurance corporation that would be taxable as an insurance company if it were a U.S. corporation and maintains insurance liabilities of more than 25% of such company’s assets for a taxable year (or maintains insurance liabilities that at least equal to 10% of its assets and it satisfies a facts and circumstances test that requires a showing that the failure to exceed the 25% threshold is due to run-off or rating agency circumstances) (the Reserve Test).

In addition, the IRS issued proposed regulations in 2015 intended to clarify the application of the PFIC provisions to an insurance company. These proposed regulations provide that a non-U.S. insurance company may only qualify for an exception to the PFIC rules if, among other things, the non-U.S. insurance company’s officers and employees perform its substantial managerial and operational activities.  This proposed regulation will not be effective unless and until adopted in final form. The Company cannot predict the likelihood of finalization of the proposed regulations or the scope, nature, or impact of the proposed regulations on it, should they be formally adopted or enacted or whether its Foreign Insurance subsidiaries will be able to satisfy the Reserve Test in future years, and the interaction of the PFIC look-through rules is not clear, no assurance may be given that the Company will not be characterized as a PFIC.


Changes in U.S. federal income tax law could materially adversely affect an investment in AGL's common shares.

The Tax Act was passed by the U.S. Congress and was signed into law on December 22, 2017, with certain provisions intended to eliminate certain perceived tax advantages of companies (including insurance companies) that have legal domiciles outside the United States but have certain U.S. connections and United States persons investing in such companies. For example, the Tax Act includes a BEAT that could make affiliate reinsurance between United States and non-U.S. members of the group economically unfeasible and a current tax on global intangible income that may result in an increase in U.S. corporate income tax imposed on U.S. group members with respect to certain earnings at their non-U.S. subsidiaries, and revises the rules applicable to PFICs and CFCs. Although the Company is currently unable to predict the ultimate impact of the Tax Act on its business, shareholders and results of operations, it is possible that the Tax Act may increase the U.S. federal income tax liability of the U.S. members of its group that cede risk to non-U.S. group members and may affect the timing and amount of U.S. federal income taxes imposed on certain U.S. shareholders. Furthermore, it is possible that other legislation could be introduced and enacted by the current Congress or future Congresses that could have an adverse impact on the Company.

U.S. federal income tax laws and interpretations regarding whether a company is engaged in a trade or business within the U.S. is a PFIC, or whether U.S. Persons would be required to include in their gross income the "subpart F income" of a CFC or RPII are subject to change, possibly on a retroactive basis. There currently are only recently proposed regulations regarding the application of the PFIC rules to insurance companies, and the regulations regarding RPII have been in proposed form since 1991. New regulations or pronouncements interpreting or clarifying such rules may be forthcoming. The Company cannot be certain if, when, or in what form such regulations or pronouncements may be implemented or made, or whether such guidance will have a retroactive effect.

An ownership change under Section 382 of the Code could have adverse U.S. federal tax consequences.

If AGL were to issue equity securities in the future, including in connection with any strategic transaction, or if previously issued securities of AGL were to be sold by the current holders, AGL may experience an "ownership change" within the meaning of Section 382 of the Code. In general terms, an ownership change would result from transactions increasing the aggregate ownership of certain stockholders in AGL's stock by more than 50 percentage points over a testing period (generally three years). If an ownership change occurred, the Company's ability to use certain tax attributes, including certain built-in losses, credits, deductions or tax basis and/or the Company's ability to continue to reflect the associated tax benefits as assets on AGL's balance sheet, may be limited. The Company cannot give any assurance that AGL will not undergo an ownership change at a time when these limitations could materially adversely affect the Company's financial condition.

A change in AGL’s U.K. tax residence or its ability to otherwise qualify for the benefits of income tax treaties to which the U.K. is a party could adversely affect an investment in AGL’s common shares.

AGL is not incorporated in the U.K. and, accordingly, is only resident in the U.K. for U.K. tax purposes if it is “centrally managed and controlled” in the U.K. Central management and control constitutes the highest level of control of a company’s affairs. AGL believes it is entitled to take advantage of the benefits of income tax treaties to which the U.K. is a party on the basis that it is has established central management and control in the U.K. AGL has obtained confirmation that there is a low risk of challenge to its residency status from HMRC under the facts as they stand today. The Board intends to manage the affairs of AGL in such a way as to maintain its status as a company that is tax-resident in the U.K. for U.K. tax purposes and to qualify for the benefits of income tax treaties to which the U.K. is a party. However, the concept of central management and control is a case-law concept that is not comprehensively defined in U.K. statute. In addition, it is a question of fact. Moreover, tax treaties may be revised in a way that causes AGL to fail to qualify for benefits thereunder. Accordingly, a change in relevant U.K. tax law or in tax treaties to which the U.K. is a party, or in AGL’s central management and control as a factual matter, or other events, could adversely affect the ability of Assured Guaranty to manage its capital in the efficient manner that it contemplated in establishing U.K. tax residence.

Changes in U.K. tax law or in AGL’s ability to satisfy all the conditions for exemption from U.K. taxation on dividend income or capital gains in respect of its direct subsidiaries could affect an investment in AGL’s common shares.

As a U.K. tax resident, AGL is subject to U.K. corporation tax in respect of its worldwide profits (both income and capital gains), subject to applicable exemptions. The rate of corporation tax is currently 19%.
With respect to income, the dividends that AGL receives from its subsidiaries should be exempt from U.K. corporation tax under the exemption contained in section 931D of the Corporation Tax Act 2009.
With respect to capital gains, if AGL were to dispose of shares in its direct subsidiaries or if it were deemed to have done so, it may realize a chargeable gain for U.K. tax purposes. Any tax charge would be based on AGL’s

original acquisition cost. It is anticipated that any such future gain should qualify for exemption under the substantial shareholding exemption in Schedule 7AC to the Taxation of Chargeable Gains Act 1992. However, the availability of such exemption would depend on facts at the time of disposal, in particular the “trading” nature of the relevant subsidiary. There is no statutory definition of what constitutes “trading” activities for this purpose and in practice reliance is placed on the published guidance of HMRC.

A change in U.K. tax law or its interpretation by HMRC, or any failure to meet all the qualifying conditions for relevant exemptions from U.K. corporation tax, could affect Assured Guaranty’s financial results of operations or its ability to provide returns to shareholders.

Assured Guaranty's financial results may be affected by measures taken in response to the OECD BEPS project.

The Organization for Economic Co-operation and Development (OECD) published its final reports on Base Erosion and Profit Shifting (the BEPS Reports) in October 2015. The recommended actions include measures to address the abuse of double tax treaties, and an updating of the definition of a “permanent establishment” and the rules for attributing profit to a permanent establishment. There are also recommended actions relating to the goal of ensuring that transfer pricing outcomes are in line with value creation, noting that the current rules may facilitate the transfer of risks or capital away from countries where the economic activity takes place. In response to this, the U.K. Government has already introduced legislation to implement changes to transfer pricing, hybrid financial instruments and the deductibility of interest and to impose country-by-country reporting obligations. The U.K. Government has also ratified the multilateral instrument, that was developed as a result of the BEPS Report, with regard to changes to the U.K. double tax treaties. Any further changes in U.K. tax law or changes in U.S. tax law in response to the BEPS Reports could adversely affect Assured Guaranty’s tax liability.

A U.K. tax, the diverted profits tax (DPT), which is levied at 25%, came into effect from April 1, 2015, and, in substance, effectively anticipated some of the recommendations emerging from the BEPS Reports. This is an anti-avoidance measure, aimed at protecting the U.K. tax base against the diversion of profits away from the U.K. tax charge. In particular, DPT may apply to profits generated by economic activities carried out in the U.K., that are not taxed in the U.K. by reason of arrangements between companies in the same multinational group and involving a low-tax jurisdiction, including co-insurance and reinsurance. It is currently unclear whether DPT would constitute a creditable tax for U.S. foreign tax credit purposes. If any member of the Assured Guaranty group is liable to DPT, this could adversely affect the Company's results of operations.

An adverse adjustment under U.K. legislation governing the taxation of U.K. tax resident holding companies on the profits of their non-U.K. subsidiaries could adversely impact Assured Guaranty’s tax liability.

Under the U.K. “controlled foreign company” regime, the income profits of non-U.K. resident companies may, in certain circumstances, be attributed to controlling U.K. resident shareholders for U.K. corporation tax purposes. The non-U.K. resident members of the Assured Guaranty group intend to operate and manage their levels of capital in such a manner that their profits would not be taxed on AGL under the U.K. CFC regime. Assured Guaranty has obtained clearance from HMRC that none of the profits of the non-U.K. resident members of the Assured Guaranty group should be subject to U.K. tax as a result of attribution under the CFC regime on the facts as they currently stand. However, a change in the way in which Assured Guaranty operates or any further change in the CFC regime, resulting in an attribution to AGL of any of the income profits of any of AGL’s non-U.K. resident subsidiaries for U.K. corporation tax purposes, could adversely affect Assured Guaranty’s financial results of operations.

Risks Related to GAAP and Applicable LawTaxation

Changes in U.S. tax laws could reduce the fairdemand or profitability of financial guaranty insurance, or negatively impact the Company's investment portfolio.

The Tax Act included provisions that could result in a reduction of supply, such as the termination of advance refunding bonds. Any such lower volume of municipal obligations could impact the amount of such obligations that could benefit from insurance. The supply of municipal bonds in 2018 was below that in 2017, possibly due at least in part to the impact of the Tax Act. In addition, the reduction of the U.S. corporate income tax rate to 21% could make municipal obligations less attractive to certain institutional investors such as banks and property and casualty insurance companies, resulting in lower demand for municipal obligations.

Further, future changes in U.S. federal, state or local laws that materially adversely affect the tax treatment of municipal securities or the market for those securities, or other changes negatively affecting the municipal securities market, may lower volume and demand for municipal obligations and also may adversely impact the Company's investment portfolio, a

significant portion of which is invested in tax-exempt instruments. These adverse changes may adversely affect the value of the Company's insured credit derivativestax-exempt portfolio, or its liquidity.

Certain of the Company's non-U.S. subsidiaries may be subject net income to volatility.U.S. tax.

The Company is requiredmanages its business so that AGL and its non-U.S. subsidiaries (other than AGRO) operate in such a manner that none of them should be subject to mark-to-marketU.S. federal tax (other than U.S. excise tax on insurance and reinsurance premium income attributable to insuring or reinsuring U.S. risks, and U.S. withholding tax on certain derivatives that it insures, including CDS that are considered derivatives under GAAP. AlthoughU.S. source investment income). However, because there is no cash flow effect from this "marking-to-market," net changesconsiderable uncertainty as to the activities which constitute being engaged in a trade or business within the U.S., the Company cannot be certain that the IRS will not contend successfully that AGL or any of its non-U.S. subsidiaries (other than AGRO) is/are engaged in a trade or business in the fair value of the derivative are reportedU.S. If AGL and its non-U.S. subsidiaries (other than AGRO) were considered to be engaged in a trade or business in the Company's consolidated statements of operationsU.S., each such company could be subject to U.S. corporate income and therefore affect its reported earnings. As a result of such treatment, and givenbranch profits taxes on the large principal balance of the Company's CDS portfolio, small changes in the market pricing for insurance of CDS will generally result in the Company recognizing material gains or losses, with material market price increases generally resulting in large reported losses under GAAP. Accordingly, the Company's GAAP earnings will be more volatile than would be suggested by the actual performanceportion of its business operations and insured portfolio.earnings effectively connected to such U.S. business.

The fair value of a credit derivative will be affected by any event causing changesAGL, AG Re and AGRO may become subject to taxes in the credit spread (i.e., the difference in interest rates between comparable securities having different credit risk) on an underlying security referenced in the credit derivative. Common events that may cause credit spreads on an underlying municipal or corporate security referenced in a credit derivative to fluctuate include changes in the state of national or regional economic conditions, industry cyclicality, changes to a company's competitive position within an industry, management changes, changes in the ratings of the underlying security, movements in interest rates, default or failure to pay interest, or any other factor leading investors to revise expectations about the issuer's ability to pay principal and interest on its debt obligations. Similarly, common events that may cause credit spreads on an underlying structured security referenced in a credit derivative to fluctuate may include the occurrence and severity of collateral defaults, changes in demographic trends and their impact on the levels of credit

enhancement, rating changes, changes in interest rates or prepayment speeds, or any other factor leading investors to revise expectations about the risk of the collateral or the ability of the servicer to collect payments on the underlying assets sufficient to pay principal and interest. The fair value of credit derivative contracts also reflects the change in the Company's own credit cost, based on the price to purchase credit protection on AGC and AGM. For discussion of the Company's fair value methodology for credit derivatives, see Part II, Item 8, Financial Statements and Supplementary Data, Note 7, Fair Value Measurement.

If a credit derivative is held to maturity and no credit loss is incurred, any unrealized gains or losses previously reported would be offset as the transactions reach maturity. Due to the complexity of fair value accounting and the application of GAAP requirements, future amendments or interpretations of relevant accounting standards may cause the Company to modify its accounting methodology in a mannerBermuda after March 2035, which may have an adverse impact on its financial results.

Change in industry and other accounting practices could impair the Company's reported financial results and impede its ability to do business.

Changes in or the issuance of new accounting standards, as well as any changes in the interpretation of current accounting guidance, may have ana material adverse effect on the Company's reported financial results including future revenues,of operations and on an investment in the Company.

The Bermuda Minister of Finance, under Bermuda's Exempted Undertakings Tax Protection Act 1966, as amended, has given AGL, AG Re and AGRO an assurance that if any legislation is enacted in Bermuda that would impose tax computed on profits or income, or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then subject to certain limitations the imposition of any such tax will not be applicable to AGL, AG Re or AGRO, or any of AGL's or its subsidiaries' operations, shares, debentures or other obligations until March 31, 2035. Given the limited duration of the Minister of Finance's assurance, the Company cannot be certain that it will not be subject to Bermuda tax after March 31, 2035.

U.S. Persons who hold 10% or more of AGL's shares directly or through non-U.S. entities may influencebe subject to taxation under the types and/U.S. controlled non-U.S. corporation rules.

Each 10% U.S. shareholder of a non-U.S. corporation that is a CFC at any time during a taxable year that owns shares in the non-U.S. corporation directly or volumeindirectly through non-U.S. entities on the last day of the non-U.S. corporation's taxable year on which it is a CFC, must include in its gross income for U.S. federal income tax purposes its pro rata share of the CFC's "subpart F income," even if the subpart F income is not distributed. In addition, upon a sale of shares of a CFC, 10% U.S. shareholders may be subject to U.S. federal income tax on a portion of their gain at ordinary income rates.

The Company believes that because of the dispersion of the share ownership in AGL, no U.S. Person who owns AGL's shares directly or indirectly through non-U.S. entities should be treated as a 10% U.S. shareholder of AGL or of any of its non-U.S. subsidiaries. However, AGL’s shares may not be as widely dispersed as the Company believes due to, for example, the application of certain ownership attribution rules, and no assurance may be given that a U.S. Person who owns the Company's shares will not be characterized as a 10% U.S. shareholder, in which case such U.S. Person may be subject to taxation under U.S. CFC rules.

U.S. Persons who hold shares may be subject to U.S. income taxation at ordinary income rates on their proportionate share of the Company's related person insurance income.

If the following conditions are true, then a U.S. Person who owns AGL's shares (directly or indirectly through non-U.S. entities) on the last day of the taxable year would be required to include in its income for U.S. federal income tax purposes such person's pro rata share of the RPII of such Foreign Insurance Subsidiary (as defined above) for the entire taxable year, determined as if such RPII were distributed proportionately only to U.S. Persons at that date, regardless of whether such income is distributed:

the Company is 25% or more owned directly, indirectly through non-U.S. entities or by attribution by U.S. Persons;

the gross RPII of AG Re or any other AGL non-U.S. subsidiary engaged in the insurance business that managementhas not made an election under section 953(d) of the Code to be treated as a U.S. corporation for all U.S. tax purposes or are CFCs owned directly or indirectly by AGUS (each, with AG Re, a Foreign Insurance Subsidiary) equals or exceeds 20% of such Foreign Insurance Subsidiary's gross insurance income in any taxable year; and


direct or indirect insureds (and persons related to such insureds) own (or are treated as owning directly or indirectly through entities) 20% or more of the voting power or value of the Company's shares.

In addition, any RPII that is includible in the income of a U.S. tax-exempt organization may choosebe treated as unrelated business taxable income.

The amount of RPII earned by a Foreign Insurance Subsidiary (generally, premium and related investment income from the direct or indirect insurance or reinsurance of any direct or indirect U.S. holder of shares or any person related to pursue.such holder) will depend on a number of factors, including the geographic distribution of a Foreign Insurance Subsidiary's business and the identity of persons directly or indirectly insured or reinsured by a Foreign Insurance Subsidiary. The Company believes that each of its Foreign Insurance Subsidiaries either should not in the foreseeable future have RPII income which equals or exceeds 20% of its gross insurance income or have direct or indirect insureds, as provided for by RPII rules, that directly or indirectly own 20% or more of either the voting power or value of AGL's shares. However, the Company cannot be certain that this will be the case because some of the factors which determine the extent of RPII may be beyond its control.

U.S. Persons who dispose of AGL's shares may be subject to U.S. income taxation at dividend tax rates on a portion of their gain, if any.

The meaning of the RPII provisions and the application thereof to AGL and its Foreign Insurance Subsidiaries is uncertain. The RPII rules in conjunction with section 1248 of the Code provide that if a U.S. Person disposes of shares in a non-U.S. insurance corporation in which U.S. Persons own (directly, indirectly, through non-U.S. entities or by attribution) 25% or more of the shares (even if the amount of gross RPII is less than 20% of the corporation's gross insurance income and the ownership of its shares by direct or indirect insureds and related persons is less than the 20% threshold), any gain from the disposition will generally be treated as dividend income to the extent of the holder's share of the corporation's undistributed earnings and profits that were accumulated during the period that the holder owned the shares. This provision applies whether or not such earnings and profits are attributable to RPII. In addition, such a holder will be required to comply with certain reporting requirements, regardless of the amount of shares owned by the holder.

In the case of AGL's shares, these RPII rules should not apply to dispositions of shares because AGL is not itself directly engaged in the insurance business. However, the RPII provisions have never been interpreted by the courts or the U.S. Treasury Department in final regulations, and regulations interpreting the RPII provisions of the Code exist only in proposed form. It is not certain whether these regulations will be adopted in their proposed form, what changes or clarifications might ultimately be made thereto, or whether any such changes, as well as any interpretation or application of the RPII rules by the IRS, the courts, or otherwise, might have retroactive effect. The U.S. Treasury Department has authority to impose, among other things, additional reporting requirements with respect to RPII.

U.S. Persons who hold common shares will be subject to adverse tax consequences if AGL is considered to be a "passive foreign investment company" for U.S. federal income tax purposes.

If AGL is considered a PFIC for U.S. federal income tax purposes, a U.S. Person who owns any shares of AGL will be subject to adverse tax consequences that could materially adversely affect its investment, including subjecting the investor to both a greater tax liability than might otherwise apply and an interest charge. The Company believes that AGL was not a PFIC for U.S. federal income tax purposes for taxable years through 2018 and, based on the application of certain PFIC look-through rules and the Company's plan of operations for the current and future years, should not be a PFIC in the future. However, as discussed above, the Tax Act limits the insurance income exception to a non-U.S. insurance company that is a qualifying insurance corporation that would be taxable as an insurance company if it were a U.S. corporation and maintains insurance liabilities of more than 25% of such company’s assets for a taxable year (or maintains insurance liabilities that at least equal to 10% of its assets and it satisfies a facts and circumstances test that requires a showing that the failure to exceed the 25% threshold is due to run-off or rating agency circumstances) (the Reserve Test).

In addition, the IRS issued proposed regulations in 2015 intended to clarify the application of the PFIC provisions to an insurance company. These proposed regulations provide that a non-U.S. insurance company may only qualify for an exception to the PFIC rules if, among other things, the non-U.S. insurance company’s officers and employees perform its substantial managerial and operational activities.  This proposed regulation will not be effective unless and until adopted in final form. The Company cannot predict the likelihood of finalization of the proposed regulations or the scope, nature, or impact of the proposed regulations on it, should they be formally adopted or enacted or whether its Foreign Insurance subsidiaries will be able to satisfy the Reserve Test in future years, and the interaction of the PFIC look-through rules is not clear, no assurance may be given that the Company will not be characterized as a PFIC.


Changes in or inability to comply with applicableU.S. federal income tax law could materially adversely affect the Company's ability to do business.an investment in AGL's common shares.

U.S. federal income tax laws and interpretations regarding whether a company is engaged in a trade or business resultswithin the U.S. is a PFIC, or whether U.S. Persons would be required to include in their gross income the "subpart F income" of a CFC or RPII are subject to change, possibly on a retroactive basis. There currently are only recently proposed regulations regarding the application of the PFIC rules to insurance companies, and prospects.the regulations regarding RPII have been in proposed form since 1991. New regulations or pronouncements interpreting or clarifying such rules may be forthcoming. The Company cannot be certain if, when, or in what form such regulations or pronouncements may be implemented or made, or whether such guidance will have a retroactive effect.

An ownership change under Section 382 of the Code could have adverse U.S. federal tax consequences.

If AGL were to issue equity securities in the future, including in connection with any strategic transaction, or if previously issued securities of AGL were to be sold by the current holders, AGL may experience an "ownership change" within the meaning of Section 382 of the Code. In general terms, an ownership change would result from transactions increasing the aggregate ownership of certain stockholders in AGL's stock by more than 50 percentage points over a testing period (generally three years). If an insurance company’s surplus declines below minimum required levels,ownership change occurred, the insurance regulatorCompany's ability to use certain tax attributes, including certain built-in losses, credits, deductions or tax basis and/or the Company's ability to continue to reflect the associated tax benefits as assets on AGL's balance sheet, may be limited. The Company cannot give any assurance that AGL will not undergo an ownership change at a time when these limitations could impose additional restrictions onmaterially adversely affect the insurer or initiate insolvency proceedings. AGM, AGC and MAC may increase surplus by various means, including obtaining capital contributions from the Company, purchasing reinsurance or entering into other loss mitigation arrangements, reducing the amount of new business written or obtaining regulatory approval to release contingency reserves. From time to time, AGM, MAC and AGC have obtained approval from their regulators to release contingency reserves based on losses and, in the case of AGM and MAC, also based on the expiration of their insured exposure.Company's financial condition.

Underaccordingly, is only resident in the Bermuda Companies Act 1981, as amended, AGL may declare or pay a dividend onlyU.K. for U.K. tax purposes if it has reasonable grounds for believingis “centrally managed and controlled” in the U.K. Central management and control constitutes the highest level of control of a company’s affairs.

However, the concept of central management and control is a case-law concept that is not comprehensively defined in AGL.U.K. statute. In addition, if, pursuantit is a question of fact. Moreover, tax treaties may be revised in a way that causes AGL to the insurance laws and related regulations of Bermuda, Maryland and New York, AGL's insurance subsidiaries cannot pay sufficient dividendsfail to AGL at the timesqualify for benefits thereunder.

Applicable insurance laws may make it difficult to effect a change of control of AGL.

Before a person can acquire control of a U.S. orcontemplated in establishing U.K. insurance company, prior written approval must be obtained from the insurance commissioner of the state or country where the insurer is domiciled. Because a person acquiring 10% or more of AGL's common shares would indirectly control the same percentage of the stock of its U.S. insurance company subsidiaries, the insurance change of control laws of Maryland, New York and the U.K. would likely apply to such a transaction. These laws may discourage potential acquisition proposals and may delay, deter or prevent a change of control of AGL, including through transactions, and in particular unsolicited transactions, that some or all of its shareholders might consider to be desirable. While AGL's Bye-Laws limit the voting power of any shareholder to less than 10%, we cannot assure you that the applicable regulatory body would agree that a shareholder who owned 10% or more of its common shares did not control the applicable insurance company subsidiary, notwithstanding the limitation on the voting power of such shares.tax residence.

Changes in U.K. tax law or in AGL’s ability to satisfy all the conditions for exemption from U.K. taxation on dividend income or capital gains in respect of its direct subsidiaries could affect an investment in AGL’s common shares.

As a U.K. tax resident, AGL is subject to U.K. corporation tax in respect of its worldwide profits (both income and capital gains), subject to applicable lawsexemptions. The rate of corporation tax is currently 19%.
With respect to income, the dividends that AGL receives from its subsidiaries should be exempt from U.K. corporation tax under the exemption contained in section 931D of the Corporation Tax Act 2009.
With respect to capital gains, if AGL were to dispose of shares in its direct subsidiaries or if it were deemed to have done so, it may realize a chargeable gain for U.K. tax purposes. Any tax charge would be based on AGL’s

original acquisition cost. It is anticipated that any such future gain should qualify for exemption under the substantial shareholding exemption in Schedule 7AC to the Taxation of Chargeable Gains Act 1992. However, the availability of such exemption would depend on facts at the time of disposal, in particular the “trading” nature of the relevant subsidiary. There is no statutory definition of what constitutes “trading” activities for this purpose and regulations resultingin practice reliance is placed on the published guidance of HMRC.

A change in U.K. tax law or its interpretation by HMRC, or any failure to meet all the qualifying conditions for relevant exemptions from BrexitU.K. corporation tax, could affect Assured Guaranty’s financial results of operations or its ability to provide returns to shareholders.

Assured Guaranty's financial results may be affected by measures taken in response to the OECD BEPS project.

The Organization for Economic Co-operation and Development (OECD) published its final reports on Base Erosion and Profit Shifting (the BEPS Reports) in October 2015. The recommended actions include measures to address the abuse of double tax treaties, and an updating of the definition of a “permanent establishment” and the rules for attributing profit to a permanent establishment. There are also recommended actions relating to the goal of ensuring that transfer pricing outcomes are in line with value creation, noting that the current rules may facilitate the transfer of risks or capital away from countries where the economic activity takes place. In response to this, the U.K. Government has already introduced legislation to implement changes to transfer pricing, hybrid financial instruments and the deductibility of interest and to impose country-by-country reporting obligations. The U.K. Government has also ratified the multilateral instrument, that was developed as a result of the BEPS Report, with regard to changes to the U.K. double tax treaties. Any further changes in U.K. tax law or changes in U.S. tax law in response to the BEPS Reports could adversely affect Assured Guaranty’s tax liability.

A U.K. tax, the diverted profits tax (DPT), which is levied at 25%, came into effect from April 1, 2015, and, in substance, effectively anticipated some of the recommendations emerging from the BEPS Reports. This is an anti-avoidance measure, aimed at protecting the U.K. tax base against the diversion of profits away from the U.K. tax charge. In particular, DPT may apply to profits generated by economic activities carried out in the U.K., that are not taxed in the U.K. by reason of arrangements between companies in the same multinational group and involving a low-tax jurisdiction, including co-insurance and reinsurance. It is currently unclear whether DPT would constitute a creditable tax for U.S. foreign tax credit purposes. If any member of the Assured Guaranty group is liable to DPT, this could adversely affect the Company.Company's results of operations.

Brexit could lead to legal uncertainty and politically divergent national laws and regulations asAn adverse adjustment under U.K. legislation governing the taxation of U.K. determines which EU laws to replace or replicate. Dependingtax resident holding companies on the termsprofits of Brexit, AGE may lose the ability to insure new transactions from London intheir non-U.K. EU and EEA countries without obtaining additional licenses, which may require a presence in another EU country. Brexit-related changes in laws and regulations may also adversely affect the Company’s surveillance and loss mitigation activities with respect to existing insured transactions in non-U.K. EU and EEA countries, especially to the extent Brexit inhibits the issuance of new guaranties in distressed situations. Brexit may also impact laws, rules and regulations applicable to U.K. entities with obligations insured by the Company andsubsidiaries could adversely impact Assured Guaranty’s tax liability.

Under the abilityU.K. “controlled foreign company” regime, the income profits of non-U.K. EUresident companies may, in certain circumstances, be attributed to controlling U.K. resident shareholders for U.K. corporation tax purposes. The non-U.K. resident members of the Assured Guaranty group intend to operate and manage their levels of capital in such a manner that their profits would not be taxed on AGL under the U.K. CFC regime. Assured Guaranty has obtained clearance from HMRC that none of the profits of the non-U.K. resident members of the Assured Guaranty group should be subject to U.K. tax as a result of attribution under the CFC regime on the facts as they currently stand. However, a change in the way in which Assured Guaranty operates or EEA citizensany further change in the CFC regime, resulting in an attribution to continue to be employed at AGE in London.AGL of any of the income profits of any of AGL’s non-U.K. resident subsidiaries for U.K. corporation tax purposes, could adversely affect Assured Guaranty’s financial results of operations.

Risks Related to Taxation

Changes in U.S. tax laws could reduce the demand or profitability of financial guaranty insurance, or negatively impact the Company's investment portfolio.

Press reports indicateThe Tax Act included provisions that could result in a reduction of supply, such as the U.S. Congress is considering making major changes to the Internal Revenue Code in 2017.termination of advance refunding bonds. Any material change in the U.S. tax treatment of municipal securities, the imposition of a national sales tax or a flat tax in lieu of the current federal income tax structure in the U.S., or changes in the treatment of dividends, could adversely affect the market for municipal obligations and, consequently, reduce the demand for financial guaranty insurance and reinsurance of such obligations. Limiting or eliminating the Federal income tax exclusion for municipal bond interest would increase the cost of borrowing for state and local governments, and as a result, could cause a decrease in infrastructure spending by states and municipalities. Municipalities may issue a lower volume of bonds, and in particular may be less likely to refund existing debt, in which case,municipal obligations could impact the amount of bondssuch obligations that cancould benefit from insurance. The supply of municipal bonds in 2018 was below that in 2017, possibly due at least in part to the impact of the Tax Act. In addition, the reduction of the U.S. corporate income tax rate to 21% could make municipal obligations less attractive to certain institutional investors such as banks and property and casualty insurance might also be reduced.companies, resulting in lower demand for municipal obligations.

ChangesFurther, future changes in U.S. federal, state or local laws that materially adversely affect the tax treatment of municipal securities or the market for those securities, or other changes negatively affecting the municipal securities market, may lower volume and demand for municipal obligations and also may adversely impact the Company's investment portfolio, a

significant portion of which is invested in tax-exempt instruments. These adverse changes may adversely affect the value of the Company's tax-exempt portfolio, or its liquidity.

Certain of the Company's foreignnon-U.S. subsidiaries may be subject to U.S. tax.

The Company manages its business so that AGL and its foreignnon-U.S. subsidiaries (other than AGRO and AGE)AGRO) operate in such a manner that none of them should be subject to U.S. federal tax (other than U.S. excise tax on insurance and reinsurance premium income attributable to insuring or reinsuring U.S. risks, and U.S. withholding tax on certain U.S. source investment income). However, because there is considerable uncertainty as to the activities which constitute being engaged in a trade or business within the U.S., the Company cannot be certain that the IRS will not contend successfully that AGL or any of its foreignnon-U.S. subsidiaries (other than AGRO and AGE)AGRO) is/are engaged in a trade or business in the U.S. If AGL and its foreignnon-U.S. subsidiaries (other than AGRO and AGE)AGRO) were considered to be engaged in a trade or business in the U.S., each such company could be subject to U.S. corporate income and branch profits taxes on the portion of its earnings effectively connected to such U.S. business.

AGL, AG Re and AGRO may become subject to taxes in Bermuda after March 2035, which may have a material adverse effect on the Company's results of operations and on an investment in the Company.

The Bermuda Minister of Finance, under Bermuda's Exempted Undertakings Tax Protection Act 1966, as amended, has given AGL, AG Re and AGRO an assurance that if any legislation is enacted in Bermuda that would impose tax computed

on profits or income, or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then subject to certain limitations the imposition of any such tax will not be applicable to AGL, AG Re or AGRO, or any of AGL's or its subsidiaries' operations, shares, debentures or other obligations until March 31, 2035. Given the limited duration of the Minister of Finance's assurance, the Company cannot be certain that it will not be subject to Bermuda tax after March 31, 2035.

U.S. Persons who hold 10% or more of AGL's shares directly or through foreignnon-U.S. entities may be subject to taxation under the U.S. controlled foreignnon-U.S. corporation rules.

Each 10% U.S. shareholder of a foreignnon-U.S. corporation that is a CFC for an uninterrupted period of 30 days or moreat any time during a taxable year and whothat owns shares in the foreignnon-U.S. corporation directly or indirectly through foreignnon-U.S. entities on the last day of the foreignnon-U.S. corporation's taxable year on which it is a CFC, must include in its gross income for U.S. federal income tax purposes its pro rata share of the CFC's "subpart F income," even if the subpart F income is not distributed. In addition, upon a sale of shares of a CFC, 10% U.S. shareholders may be subject to U.S. federal income tax on a portion of their gain at ordinary income rates.

The Company believes that because of the dispersion of the share ownership in AGL, provisions in AGL's Bye-Laws that limit voting power, contractual limits on voting power and other factors, no U.S. Person who owns AGL's shares directly or indirectly through foreignnon-U.S. entities should be treated as a 10% U.S. shareholder of AGL or of any of its foreignnon-U.S. subsidiaries. It is possible, however, thatHowever, AGL’s shares may not be as widely dispersed as the IRS could challengeCompany believes due to, for example, the effectivenessapplication of these provisionscertain ownership attribution rules, and no assurance may be given that a court could sustain suchU.S. Person who owns the Company's shares will not be characterized as a challenge,10% U.S. shareholder, in which case such U.S. Person may be subject to taxation under U.S. taxCFC rules.

U.S. Persons who hold shares may be subject to U.S. income taxation at ordinary income rates on their proportionate share of the Company's related person insurance income.

If the following conditions are true, then a U.S. Person who owns AGL's shares (directly or indirectly through foreignnon-U.S. entities) on the last day of the taxable year would be required to include in its income for U.S. federal income tax purposes such person's pro rata share of the RPII of such Foreign Insurance Subsidiary (as defined below)above) for the entire taxable year, determined as if such RPII were distributed proportionately only to U.S. Persons at that date, regardless of whether such income is distributed:

the Company is 25% or more owned directly, indirectly through foreignnon-U.S. entities or by attribution by U.S. Persons;

the gross RPII of AG Re or any other AGL foreignnon-U.S. subsidiary engaged in the insurance business that has not made an election under section 953(d) of the Code to be treated as a U.S. corporation for all U.S. tax purposes or are CFCs owned directly or indirectly by AGUS (each, with AG Re, a Foreign Insurance Subsidiary) were to equalequals or exceedexceeds 20% of such Foreign Insurance Subsidiary's gross insurance income in any taxable year; and


direct or indirect insureds (and persons related to such insureds) own (or are treated as owning directly or indirectly through entities) 20% or more of the voting power or value of the Company's shares.

In addition, any RPII that is includible in the income of a U.S. tax-exempt organization may be treated as unrelated business taxable income.

The amount of RPII earned by a Foreign Insurance Subsidiary (generally, premium and related investment income from the direct or indirect insurance or reinsurance of any direct or indirect U.S. holder of shares or any person related to such holder) will depend on a number of factors, including the geographic distribution of a Foreign Insurance Subsidiary's business and the identity of persons directly or indirectly insured or reinsured by a Foreign Insurance Subsidiary. The Company believes that each of its Foreign Insurance Subsidiaries either should not in the foreseeable future have RPII income which equals or exceeds 20% of its gross insurance income or have direct or indirect insureds, as provided for by RPII rules, that directly or indirectly own 20% or more of either the voting power or value of AGL's shares. However, the Company cannot be certain that this will be the case because some of the factors which determine the extent of RPII may be beyond its control.


U.S. Persons who dispose of AGL's shares may be subject to U.S. income taxation at dividend tax rates on a portion of their gain, if any.

The meaning of the RPII provisions and the application thereof to AGL and its Foreign Insurance Subsidiaries is uncertain. The RPII rules in conjunction with section 1248 of the Code provide that if a U.S. Person disposes of shares in a foreignnon-U.S. insurance corporation in which U.S. Persons own (directly, indirectly, through foreignnon-U.S. entities or by attribution) 25% or more of the shares (even if the amount of gross RPII is less than 20% of the corporation's gross insurance income and the ownership of its shares by direct or indirect insureds and related persons is less than the 20% threshold), any gain from the disposition will generally be treated as dividend income to the extent of the holder's share of the corporation's undistributed earnings and profits that were accumulated during the period that the holder owned the shares. This provision applies whether or not such earnings and profits are attributable to RPII. In addition, such a holder will be required to comply with certain reporting requirements, regardless of the amount of shares owned by the holder.

In the case of AGL's shares, these RPII rules should not apply to dispositions of shares because AGL is not itself directly engaged in the insurance business. However, the RPII provisions have never been interpreted by the courts or the U.S. Treasury Department in final regulations, and regulations interpreting the RPII provisions of the Code exist only in proposed form. It is not certain whether these regulations will be adopted in their proposed form, what changes or clarifications might ultimately be made thereto, or whether any such changes, as well as any interpretation or application of the RPII rules by the IRS, the courts, or otherwise, might have retroactive effect. The U.S. Treasury Department has authority to impose, among other things, additional reporting requirements with respect to RPII.

U.S. Persons who hold common shares will be subject to adverse tax consequences if AGL is considered to be a "passive foreign investment company" for U.S. federal income tax purposes.

If AGL is considered a PFIC for U.S. federal income tax purposes, a U.S. Person who owns any shares of AGL will be subject to adverse tax consequences that could materially adversely affect its investment, including subjecting the investor to both a greater tax liability than might otherwise apply and an interest charge. The Company believes that AGL iswas not and currently does not expect AGL to become, a PFIC for U.S. federal income tax purposes; however, there can be no assurance that AGL will not be deemed a PFIC by the IRS.

There are currently no final or temporary regulations regardingpurposes for taxable years through 2018 and, based on the application of certain PFIC look-through rules and the Company's plan of operations for the current and future years, should not be a PFIC provisionsin the future. However, as discussed above, the Tax Act limits the insurance income exception to a non-U.S. insurance company that is a qualifying insurance corporation that would be taxable as an insurance company. Thecompany if it were a U.S. corporation and maintains insurance liabilities of more than 25% of such company’s assets for a taxable year (or maintains insurance liabilities that at least equal to 10% of its assets and it satisfies a facts and circumstances test that requires a showing that the failure to exceed the 25% threshold is due to run-off or rating agency circumstances) (the Reserve Test).

In addition, the IRS recently issued proposed regulations in 2015 intended to clarify the application of the PFIC provisions to an insurance company. These proposed regulations provide that a non-U.S. insurance company may only qualify for an exception to the PFIC rules if, among other things, the non-U.S. insurance company’s officers and employees perform its substantial managerial and operational activities.  This proposed regulation will not be effective unless and until adopted in final form. BecauseThe Company cannot predict the likelihood of the legal uncertainties relating to howfinalization of the proposed regulations or the scope, nature, or impact of the proposed regulations on it, should they be formally adopted or enacted or whether its Foreign Insurance subsidiaries will be interpretedable to satisfy the Reserve Test in future years, and the form in which such regulations or any legislative proposalinteraction of the PFIC look-through rules is not clear, no assurance may be finalized,given that the Company cannot predict what impact, if any, such guidance or legislation would have on an investor that is subject to U.S. federal income tax.will not be characterized as a PFIC.


Changes in U.S. federal income tax law could materially adversely affect an investment in AGL's common shares.

Legislation has been introduced inThe Tax Act was passed by the U.S. Congress and was signed into law on December 22, 2017, with certain provisions intended to eliminate certain perceived tax advantages of companies (including insurance companies) that have legal domiciles outside the U.S.United States but have certain U.S. connections.connections and United States persons investing in such companies. For example, legislation has been introducedthe Tax Act includes a BEAT that could make affiliate reinsurance between United States and non-U.S. members of the group economically unfeasible and a current tax on global intangible income that may result in Congressan increase in U.S. corporate income tax imposed on U.S. group members with respect to limitcertain earnings at their non-U.S. subsidiaries, and revises the deductibilityrules applicable to PFICs and CFCs. Although the Company is currently unable to predict the ultimate impact of reinsurance premiums paid by U.S. insurance companies to foreign affiliatesthe Tax Act on its business, shareholders and impose additional limits on deductibilityresults of interest of foreign owned U.S. corporations. Another legislative proposal would treat a foreign corporationoperations, it is possible that is primarily managed and controlled inthe Tax Act may increase the U.S. as a U.S. corporation for U.S federal income tax purposes. Further, legislation based on the Tax Reform Task-Force Blueprint dated June 24, 2016, which recommends moving to a cash flow consumption-based tax system and provides for border adjustments taxing imports, may be introduced and enacted and its impact on the insurance industry may adversely impact the results of our operations. Also, legislation has previously been introduced to override the reduction or eliminationliability of the U.S. withholding taxmembers of its group that cede risk to non-U.S. group members and may affect the timing and amount of U.S. federal income taxes imposed on certain U.S. source investment income under a tax treaty in the case of a deductible related party payment made by a U.S. member of a foreign controlled group to a foreign member of the group organized in a tax treaty country to the extent that the ultimate foreign parent corporation would not enjoy the treaty benefits with respect to such payments. Itshareholders. Furthermore, it is possible that this or similarother legislation could be introduced in and enacted by the current Congress or future Congresses that could have an adverse impact on the Company or the Company's shareholders.Company.

U.S. federal income tax laws and interpretations regarding whether a company is engaged in a trade or business within the U.S. is a PFIC, or whether U.S. Persons would be required to include in their gross income the "subpart F income" of a CFC or RPII are subject to change, possibly on a retroactive basis. There currently are only recently proposed regulations

regarding the application of the PFIC rules to insurance companies, and the regulations regarding RPII have been in proposed form since 1991. New regulations or pronouncements interpreting or clarifying such rules may be forthcoming. The Company cannot be certain if, when, or in what form such regulations or pronouncements may be implemented or made, or whether such guidance will have a retroactive effect.

Recharacterization by the Internal Revenue Service of the Company's U.S. federal tax treatment of losses on the Company's CDS portfolio can adversely affect the Company's financial position.

As part of the Company's financial guaranty business, the Company has sold credit protection by insuring CDS entered into with various financial institutions. Assured Guaranty's CDS portfolio has experienced significant cumulative fair value losses which are only deductible for U.S. federal income tax purposes upon realization and, consequently, generate a significant deferred tax asset based on the Company's intended treatment of such losses as ordinary insurance losses upon realization. The U.S. federal income tax treatment of CDS is an unsettled area of the tax law. As such, it is possible that the IRS may decide that the losses generated by the Company's CDS business should be characterized as capital rather than ordinary insurance losses, which could materially adversely affect the Company's financial condition.

An ownership change under Section 382 of the Code could have adverse U.S. federal tax consequences.

If AGL were to issue equity securities in the future, including in connection with any strategic transaction, or if previously issued securities of AGL were to be sold by the current holders, AGL may experience an "ownership change" within the meaning of Section 382 of the Code. In general terms, an ownership change would result from transactions increasing the aggregate ownership of certain stockholders in AGL's stock by more than 50 percentage points over a testing period (generally three years). If an ownership change occurred, the Company's ability to use certain tax attributes, including certain built-in losses, credits, deductions or tax basis and/or the Company's ability to continue to reflect the associated tax benefits as assets on AGL's balance sheet, may be limited. The Company cannot give any assurance that AGL will not undergo an ownership change at a time when these limitations could materially adversely affect the Company's financial condition.

AGMH likely experienced an ownership change under Section 382 of the Code.

In connection with the acquisition of AGMH, AGMH likely experienced an "ownership change" within the meaning of Section 382 of the Code. The Company has concluded that the Section 382 limitations as discussed in "An ownership change under Section 382 of the Code could have adverse U.S. federal tax consequences" are unlikely to have any material tax or accounting consequences. However, this conclusion is based on a variety of assumptions, including the Company's estimates regarding the amount and timing of certain deductions and future earnings, any of which could be incorrect. Accordingly, there can be no assurance that these limitations would not have an adverse effect on the Company's financial condition or that such adverse effects would not be material.

A change in AGL’s U.K. tax residence or its ability to otherwise qualify for the benefits of income tax treaties to which the U.K. is a party could adversely affect an investment in AGL’s common shares.

AGL is not incorporated in the U.K. and, accordingly, is only resident in the U.K. for U.K. tax purposes if it is “centrally managed and controlled” in the U.K. Central management and control constitutes the highest level of control of a company’s affairs. AGL believes it is entitled to take advantage of the benefits of income tax treaties to which the U.K. is a party on the basis that it is has established central management and control in the U.K. AGL has obtained confirmation that there is a low risk of challenge to its residency status from HMRC under the facts as they stand today. The Board intends to manage the affairs of AGL in such a way as to maintain its status as a company that is tax-resident in the U.K. for U.K. tax purposes and to qualify for the benefits of income tax treaties to which the U.K. is a party. However, the concept of central management and control is a case-law concept that is not comprehensively defined in U.K. statute. In addition, it is a question of fact. Moreover, tax treaties may be revised in a way that causes AGL to fail to qualify for benefits thereunder. Accordingly, a change in relevant U.K. tax law or in tax treaties to which the U.K. is a party, or in AGL’s central management and control as a factual matter, or other events, could adversely affect the ability of Assured Guaranty to manage its capital in the efficient manner that it contemplated in establishing U.K. tax residence.

Changes in U.K. tax law or in AGL’s ability to satisfy all the conditions for exemption from U.K. taxation on dividend income or capital gains in respect of its direct subsidiaries could affect an investment in AGL’s common shares.

As a U.K. tax resident, AGL is subject to U.K. corporation tax in respect of its worldwide profits (both income and capital gains), subject to applicable exemptions. The main rate of corporation tax is currently 20%19%.

With respect to income, the dividends that AGL receives from its subsidiaries should be exempt from U.K. corporation tax under the exemption contained in section 931D of the Corporation Tax Act 2009.
With respect to capital gains, if AGL were to dispose of shares in its direct subsidiaries or if it were deemed to have done so, it may realize a chargeable gain for U.K. tax purposes. Any tax charge would be based on AGL’s

original acquisition cost. It is anticipated that any such future gain should qualify for exemption under the substantial shareholding exemption in Schedule 7AC to the Taxation of Chargeable Gains Act 1992. However, the availability of such exemption would depend on facts at the time of disposal, in particular the “trading” nature of the relevant subsidiary (and, in respect of disposal before April 1, 2017 only, the Assured Guaranty group).subsidiary. There is no statutory definition of what constitutes “trading” activities for this purpose and in practice reliance is placed on the published guidance of HMRC.

A change in U.K. tax law or its interpretation by HMRC, or any failure to meet all the qualifying conditions for relevant exemptions from U.K. corporation tax, could affect Assured Guaranty’s financial results of operations or its ability to provide returns to shareholders.

Assured Guaranty's financial results may be affected by measures taken in response to the OECD BEPS project.

The Organization for Economic Co-operation and Development (OECD) published its final reports on Base Erosion and Profit Shifting (the BEPS Reports) in October 2015. The recommended actions include measures to address the abuse of double tax treaties, and an examinationupdating of the definition of a “permanent establishment” and the rules for attributing profit to a permanent establishment. There are also recommended actions relating to the goal of ensuring that transfer pricing outcomes are in line with value creation, noting that the current rules may facilitate the transfer of risks or capital away from countries where the economic activity takes place. In response to this, the U.K. Government has already made or proposed draftintroduced legislation to implement changes to transfer pricing, hybrid financial instruments and the deductibility of interest.interest and to impose country-by-country reporting obligations. The U.K. Government has also ratified the multilateral instrument, that was developed as a result of the BEPS Report, with regard to changes to the U.K. double tax treaties. Any further changes in U.K. tax law or changes in U.S. tax law in response to the BEPS Reports could adversely affect Assured Guaranty’s tax liability.

A new U.K. tax, the diverted profits tax (DPT), which is levied at 25%, came into effect from April 1, 2015, and, in substance, effectively anticipated some of the recommendations emerging from the BEPS Reports. This is an anti-avoidance measure, aimed at protecting the U.K. tax base against the diversion of profits away from the U.K. tax charge. In particular, DPT may apply to profits generated by economic activities carried out in the U.K., that are not taxed in the U.K. by reason of arrangements between companies in the same multinational group and involving a low-tax jurisdiction, including co-insurance and reinsurance. It is currently unclear whether DPT would constitute a creditable tax for U.S. foreign tax credit purposes. If any member of the Assured Guaranty group is liable to DPT, this could adversely affect the Company's results of operations.

An adverse adjustment under U.K. legislation governing the taxation of U.K. tax resident holding companies on the profits of their foreignnon-U.K. subsidiaries could adversely impact Assured Guaranty’s tax liability.

Under the U.K. “controlled foreign company” regime, the income profits of non-U.K. resident companies may, in certain circumstances, be attributed to controlling U.K. resident shareholders for U.K. corporation tax purposes. The non-U.K. resident members of the Assured Guaranty group intend to operate and manage their levels of capital in such a manner that their profits would not be taxed on AGL under the U.K. CFC regime. Assured Guaranty has obtained clearance from HMRC that none of the profits of the non-U.K. resident members of the Assured Guaranty group should be subject to U.K. tax as a result of attribution under the CFC regime on the facts as they currently stand. However, a change in the way in which Assured Guaranty operates or any further change in the CFC regime, resulting in an attribution to AGL of any of the income profits of any of AGL’s non-U.K. resident subsidiaries for U.K. corporation tax purposes, could adversely affect Assured Guaranty’s financial results of operations.

Risks Related to GAAP and Applicable Law

Changes in the fair value of the Company's insured credit derivatives portfolio may subject net income to volatility.

The Company is required to mark-to-market certain derivatives that it insures, including CDS that are considered derivatives under GAAP. Although there is no cash flow effect from this "marking-to-market," net changes in the fair value of the derivative are reported in the Company's consolidated statements of operations and therefore affect its reported earnings. As a result of such treatment, and given the principal balance of the Company's CDS portfolio, small changes in the market pricing for insurance of CDS will generally result in the Company recognizing material gains or losses, with material market price increases generally resulting in material reported losses under GAAP. Accordingly, the Company's GAAP earnings will be more volatile than would be suggested by the actual performance of its business operations and insured portfolio.

The fair value of a credit derivative will be affected by any event causing changes in the credit spread (i.e., the difference in interest rates between comparable securities having different credit risk) on an underlying security referenced in the credit derivative. Common events that may cause credit spreads on an underlying municipal or corporate security

referenced in a credit derivative to fluctuate include changes in the state of national or regional economic conditions, industry cyclicality, changes to a company's competitive position within an industry, management changes, changes in the ratings of the underlying security, movements in interest rates, default or failure to pay interest, or any other factor leading investors to revise expectations about the issuer's ability to pay principal and interest on its debt obligations. Similarly, common events that may cause credit spreads on an underlying structured security referenced in a credit derivative to fluctuate may include the occurrence and severity of collateral defaults, changes in demographic trends and their impact on the levels of credit enhancement, rating changes, changes in interest rates or prepayment speeds, or any other factor leading investors to revise expectations about the risk of the collateral or the ability of the servicer to collect payments on the underlying assets sufficient to pay principal and interest. The fair value of credit derivative contracts also reflects the change in the Company's own credit cost, based on the price to purchase credit protection on AGC and AGM. For discussion of the Company's fair value methodology for credit derivatives, see Part II, Item 8, Financial Statements and Supplementary Data, Note 7, Fair Value Measurement.

If a credit derivative is held to maturity and no credit loss is incurred, any unrealized gains or losses previously reported would be offset as the transactions reach maturity. Due to the complexity of fair value accounting and the application of GAAP requirements, future amendments or interpretations of relevant accounting standards may cause the Company to modify its accounting methodology in a manner which may have an adverse impact on its financial results.

Change in industry and other accounting practices could impair the Company's reported financial results and impede its ability to do business.

Changes in or the issuance of new accounting standards, as well as any changes in the interpretation of current accounting guidance, may have an adverse effect on the Company's reported financial results, including future revenues, and may influence the types and/or volume of business that management may choose to pursue. See Part II, Item 8, Financial Statements and Supplementary Data, Note 1, Business and Basis of Presentation, for a discussion of the future application of accounting standards.

Changes in or inability to comply with applicable law could adversely affect the Company's ability to do business.

The Company’s businesses are subject to direct and indirect regulation under state insurance laws, federal securities, commodities and tax laws affecting public finance and asset backed obligations, and federal regulation of derivatives, as well as applicable laws in the other countries in which the Company operates. Future legislative, regulatory, judicial or other legal changes in the jurisdictions in which the Company does business may adversely affect its ability to pursue its current mix of business, thereby materially impacting its financial results by, among other things, limiting the types of risks it may insure, lowering applicable single or aggregate risk limits, increasing required reserves or capital, increasing the level of supervision or regulation to which the Company’s operations may be subject, imposing restrictions that make the Company’s products less attractive to potential buyers, lowering the profitability of the Company’s business activities, requiring the Company to change certain of its business practices and exposing it to additional costs (including increased compliance costs).

If the Company fails to comply with applicable insurance laws and regulations it could be exposed to fines, the loss of insurance licenses, limitations on the right to originate new business and restrictions on its ability to pay dividends, all of which could have an adverse impact on its business results and prospects. If an insurance company’s surplus declines below minimum required levels, the insurance regulator could impose additional restrictions on the insurer or initiate insolvency proceedings. AGM, AGC and MAC may increase surplus by various means, including obtaining capital contributions from the Company, purchasing reinsurance or entering into other loss mitigation arrangements, reducing the amount of new business written or obtaining regulatory approval to release contingency reserves. From time to time, AGM, MAC and AGC have obtained approval from their regulators to release contingency reserves based on losses and, in the case of AGM and MAC, also based on the expiration of their insured exposure.

AGL's ability to pay dividends may be constrained by certain insurance regulatory requirements and restrictions.

AGL is subject to Bermuda regulatory requirements that affect its ability to pay dividends on common shares and to make other payments. Under the Bermuda Companies Act 1981, as amended, AGL may declare or pay a dividend only if it has reasonable grounds for believing that it is, and after the payment would be, able to pay its liabilities as they become due, and if the realizable value of its assets would not be less than its liabilities. While AGL currently intends to pay dividends on its common shares, investors who require dividend income should carefully consider these risks before investing in AGL. In addition, if, pursuant to the insurance laws and related regulations of Bermuda, Maryland and New York, AGL's insurance subsidiaries cannot pay sufficient dividends to AGL at the times or in the amounts that it requires, it would have an adverse

effect on AGL's ability to pay dividends to shareholders. See "Risks Related to the Company's Capital and Liquidity Requirements—The ability of AGL and its subsidiaries to meet their liquidity needs may be limited."

Applicable insurance laws may make it difficult to effect a change of control of AGL.

Before a person can acquire control of a U.S. or U.K. insurance company, prior written approval must be obtained from the insurance commissioner of the state or country where the insurer is domiciled. Because a person acquiring 10% or more of AGL's common shares would indirectly control the same percentage of the stock of its U.S. insurance company subsidiaries, the insurance change of control laws of Maryland, New York and the U.K. would likely apply to such a transaction. These laws may discourage potential acquisition proposals and may delay, deter or prevent a change of control of AGL, including through transactions, and in particular unsolicited transactions, that some or all of its shareholders might consider to be desirable. While AGL's Bye-Laws limit the voting power of any shareholder to less than 10%, the Company cannot provide assurances that the applicable regulatory body would agree that a shareholder who owned 10% or more of its common shares did not control the applicable insurance company subsidiary, notwithstanding the limitation on the voting power of such shares.

Changes in applicable laws and regulations resulting from Brexit may adversely affect the Company.

As described above in Part 1, Item 1, Business, Regulation, on June 23, 2016, a referendum was held in the U.K. in which a majority voted to exit the EU, known as “Brexit”, and there has been no approval by the U.K. Parliament of the withdrawal agreement between the EU and the U.K. Failing such approval or the implementation of an agreed extension to the U.K.'s planned departure date, it is currently expected that the U.K. will leave the EU on March 29, 2019 under a No-Deal Brexit.

    Given the lack of clarity on the ultimate post-Brexit relationship between Great Britain and the EU, the Company cannot fully determine what, if any, impact Brexit may have on its operations, both inside and outside the U.K. For example, the Company cannot determine whether U.K. authorized financial services firms such as AGE will continue to enjoy passporting rights to the other 27 EEA states after Brexit. This question will be particularly acute in the event of a No-Deal Brexit because the loss of passporting could occur as early as March 29, 2019, rather than at the end of the transition period under the withdrawal agreement of December 31, 2020. As a consequence, Assured Guaranty is establishing a new subsidiary in Paris, France, in order to continue with the ability to write new business, and to service existing business, in those other EEA states. That new subsidiary is unlikely to be fully licensed prior to a No-Deal Brexit, should that occur. While the Company believes that, in the event of a No-Deal Brexit or in the absence of applicable transition rules, those other EEA states outside the U.K. will permit the Company to continue to service existing business in their states, there can be no assurance that this will occur, nor can the Company fully determine the impact on its business and operations if it does not occur.

See also "Brexit may adversely impact exposures insured by the Company and may also impact the Company through currency exchange rates" under Risks Related to the Financial, Credit and Guaranty Markets.




Risks Related to AGL's Common Shares

The market price of AGL's common shares may be volatile, which could cause the value of an investment in the Company to decline.

The market price of AGL's common shares has experienced, and may continue to experience, significant volatility. Numerous factors, including many over which the Company has no control, may have a significant impact on the market price of its common shares. These risks include those described or referred to in this "Risk Factors" section as well as, among other things:


investor perceptions of the Company, its prospects and that of the financial guaranty industry and the markets in which the Company operates;

the Company's operating and financial performance;

the Company's access to financial and capital markets to raise additional capital, refinance its debt or replace existing senior secured credit and receivables-backed facilities;

the Company's ability to repay debt;

the Company's dividend policy;

the amount of share repurchases authorized by the Company;

future sales of equity or equity-related securities;

changes in earnings estimates or buy/sell recommendations by analysts; and

general financial, economic and other market conditions.

In addition, the stock market in recent years has experienced extreme price and trading volume fluctuations that often have been unrelated or disproportionate to the operating performance of individual companies. These broad market fluctuations may adversely affect the price of AGL's common shares, regardless of its operating performance.

Furthermore, future sales or other issuances of AGL equity may adversely affect the market price of its common shares.

AGL's common shares are equity securities and are junior to existing and future indebtedness.

As equity interests, AGL's common shares rank junior to indebtedness and to other non-equity claims on AGL and its assets available to satisfy claims on AGL, including claims in a bankruptcy or similar proceeding. For example, upon liquidation, holders of AGL debt securities and shares of preferred stock and creditors would receive distributions of AGL's available assets prior to the holders of AGL common shares. Similarly, creditors, including holders of debt securities, of AGL's subsidiaries, have priority on the assets of those subsidiaries. Future indebtedness may restrict payment of dividends on the common shares.

Additionally, unlike indebtedness, where principal and interest customarily are payable on specified due dates, in the case of common shares, dividends are payable only when and if declared by AGL's Board or a duly authorized committee of the Board. Further, the common shares place no restrictions on its business or operations or on its ability to incur indebtedness or engage in any transactions, subject only to the voting rights available to stockholders generally.

Provisions in the Code and AGL's Bye-Laws may reduce or increase the voting rights of its common shares.

Under the Code, AGL's Bye-Laws and contractual arrangements, certain shareholders have their voting rights limited to less than one vote per share, resulting in other shareholders having voting rights in excess of one vote per share. Moreover, the relevant provisions of the Code and AGL's Bye-Laws may have the effect of reducing the votes of certain shareholders who would not otherwise be subject to the limitation by virtue of their direct share ownership.

More specifically, pursuant to the relevant provisions of the Code, if, and so long as, the common shares of a shareholder are treated as "controlled shares" (as determined under section 958 of the Code) of any U.S. Person (as defined below) and such

controlled shares constitute 9.5% or more of the votes conferred by AGL's issued shares, the voting rights with respect to the controlled shares of such U.S. Person (a 9.5% U.S. Shareholder) are limited, in the aggregate, to a voting power of less than 9.5%, under a formula specified in AGL's Bye-Laws. The formula is applied repeatedly until the voting power of all 9.5% U.S. Shareholders has been reduced to less than 9.5%. For these purposes, "controlled shares" include, among other things, all shares of AGL that such U.S. Person is deemed to own directly, indirectly or constructively (within the meaning of section 958 of the Code).

In addition, the Board may limit a shareholder's voting rights where it deems appropriate to do so to (1) avoid the existence of any 9.5% U.S. Shareholders, and (2) avoid certain material adverse tax, legal or regulatory consequences to the

Company or any of the Company's subsidiaries or any shareholder or its affiliates. AGL's Bye-Laws provide that shareholders will be notified of their voting interests prior to any vote taken by them.

As a result of any such reallocation of votes, the voting rights of a holder of AGL common shares might increase above 5% of the aggregate voting power of the outstanding common shares, thereby possibly resulting in such holder becoming a reporting person subject to Schedule 13D or 13G filing requirements under the Securities Exchange Act of 1934. In addition, the reallocation of votes could result in such holder becoming subject to the short swing profit recovery and filing requirements under Section 16 of the Exchange Act.

AGL also has the authority under its Bye-Laws to request information from any shareholder for the purpose of determining whether a shareholder's voting rights are to be reallocated under the Bye-Laws. If a shareholder fails to respond to a request for information or submits incomplete or inaccurate information in response to a request, the Company may, in its sole discretion, eliminate such shareholder's voting rights.

Provisions in AGL's Bye-Laws may restrict the ability to transfer common shares, and may require shareholders to sell their common shares.

AGL's Board may decline to approve or register a transfer of any common shares (1) if it appears to the Board, after taking into account the limitations on voting rights contained in AGL's Bye-Laws, that any adverse tax, regulatory or legal consequences to AGL, any of its subsidiaries or any of its shareholders may occur as a result of such transfer (other than such as the Board considers to be de minimis), or (2) subject to any applicable requirements of or commitments to the NYSE, if a written opinion from counsel supporting the legality of the transaction under U.S. securities laws has not been provided or if any required governmental approvals have not been obtained.

AGL's Bye-Laws also provide that if the Board determines that share ownership by a person may result in adverse tax, legal or regulatory consequences to the Company, any of the subsidiaries or any of the shareholders (other than such as the Board considers to be de minimis), then AGL has the option, but not the obligation, to require that shareholder to sell to AGL or to third parties to whom AGL assigns the repurchase right for fair market value the minimum number of common shares held by such person which is necessary to eliminate such adverse tax, legal or regulatory consequences.

ITEM 2.PROPERTIES

The principal executive offices of AGL and AG Re consist of approximately 8,250 square feet of office space located in Hamilton, Bermuda; the lease for this space expires in April 2021 and is renewable at the option of the Company.

In addition,The U.S. subsidiaries of the Company had been occupying offices at 31 West 52nd Street in New York City. In September 2015, the Company entered into a lease for 88,000103,500 square feet of office space at 1633 Broadway in New York City, and later an additional 15,500 square feet for a total of 103,500 square feet;City; the new lease expires in February 2032, with an option, subject to certain conditions, to renew for five years at a fair market rent. The Company agreed to terminate its existingU.S. subsidiaries also lease in August 2016 and relocated its U.S. affiliates into the new office space in the summer of 2016.

Furthermore, the Company has officesSan Francisco. In addition, AGE leases space in San Francisco and London. During 2016, the Company moved its London offices from 1 Finsbury Square to 6 Bevis Marks.

Management believes its office space is adequate for its current and anticipated needs.


ITEM 3.LEGAL PROCEEDINGS

Lawsuits arise in the ordinary course of the Company's business. It is the opinion of the Company's management, based upon the information available, that the expected outcome of litigation against the Company, individually or in the aggregate, will not have a material adverse effect on the Company's financial position or liquidity, although an adverse resolution of litigation against the Company in a fiscal quarter or year could have a material adverse effect on the Company's results of operations in a particular quarter or year.



In addition, in the ordinary course of their respective businesses, certain of the Company's subsidiaries assert claims in legal proceedings against third parties to recover losses paid in prior periods or prevent losses in the future, including those describedfuture. For example, the Company has commenced a number of legal actions in the U.S. District Court for the District of Puerto Rico to enforce its rights with respect to the obligations it insures of Puerto Rico and various of its related authorities and public corporations. See the "Exposure to Puerto Rico" section of Part II, Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure, for a description of such actions. See also the "Recovery Litigation" section of Part II, Item 8, Financial Statements and Supplementary Data, Note 5, Expected LossLosses to be Paid, Recovery Litigation. For example, as described there, in January 2016 the Company commenced an action for declaratory judgment and injunctive relief in the U.S. District Court for the Districta description of recovery litigation unrelated to Puerto Rico to invalidate executive orders issued by the Governor of Puerto Rico directing the retention or transfer of certain taxes and revenues pledged to secure the payment of certain bonds insured by the Company, and in July 2016, the Company filed a motion and form of complaint in the U.S. District Court for the District of Puerto Rico seeking relief from the PROMESA stay in order to file a complaint to protect its interest in certain pledged PRHTA toll revenues. As another example, in December 2008, the Company filed a claim in the Supreme Court of the State of New York against an investment manager in a transaction it insured alleging breach of fiduciary duty, gross negligence and breach of contract.Rico. The amounts, if any, the Company will recover in these and other proceedings to recover losses are uncertain, and recoveries, or failure to obtain recoveries, in any one or more of these proceedings during any quarter or year could be material to the Company's results of operations in that particular quarter or year.

The Company establishes accruals for litigation and regulatory matters to the extent it is probable that a loss has been incurred and the amount of that loss can be reasonably estimated. For litigation and regulatory matters where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established, but if the matter is material, it is disclosed, including matters discussed below. The Company reviews relevant information with respect to its litigation and regulatory matters on a quarterly and annual basis and updates its accruals, disclosures and estimates of reasonably possible loss based on such reviews.

The Company receives subpoenas duces tecum and interrogatories from regulators from time to time.

On November 28, 2011, Lehman Brothers International (Europe) (in administration) (LBIE) sued AG Financial Products Inc. (AGFP), an affiliate of AGC which in the past had provided credit protection to counterparties under credit default swaps.CDS. AGC acts as the credit support provider of AGFP under these credit default swaps. LBIE'sCDS. LBIE’s complaint, which was filed in the Supreme Court of the State of New York, alleged that AGFP improperly terminatedasserted a claim for breach of the implied covenant of good faith and fair dealing based on AGFP's termination of nine credit derivative transactions between LBIE and AGFP and improperly calculatedasserted claims for breach of contract and breach of the termination payment in connection with theimplied covenant of good faith fair dealing based on AGFP's termination of 28 other credit derivative transactions between LBIE and AGFP.AGFP and AGFP's calculation of the termination payment in connection with those 28 other credit derivative transactions. Following defaults by LBIE, AGFP properly terminated the transactions in question in compliance with the agreement between AGFP and LBIE, and calculated the termination payment properly. AGFP calculated that LBIE owes AGFP approximately $29 million in connection with the termination of the credit derivative transactions, whereas LBIE asserted in the complaint that AGFP owes LBIE a termination payment of approximately $1.4 billion. On February 3, 2012, AGFP filed a motion to dismiss certainthe claims for breach of the countsimplied covenant of good faith in theLBIE's complaint, and on March 15, 2013, the court granted AGFP's motion to dismiss in respect of the count relating to improper termination of the nine credit derivative transactions and denied AGFP's motion to dismiss the counts relatingnarrowed LBIE's claim with respect to the remaining28 other credit derivative transactions. On February 22, 2016, AGFP filed a motion for summary judgment on the remaining causes of action asserted by LBIE and on AGFP's counterclaims. LBIE’sLBIE's administrators disclosed in an April 10, 2015 report to LBIE’s unsecured creditors that LBIE's valuation expert has calculated LBIE's claim for damages in aggregate for the 28 transactions to range between a minimum of approximately $200 million and a maximum of approximately $500 million, depending on what adjustment, if any, is made for AGFP's credit risk and excluding any applicable interest.

On September 25, 2013, Wells Fargo Bank, N.A., as trust administrator AGFP filed a motion for summary judgment on the remaining causes of action asserted by LBIE and on AGFP's counterclaims, and on July 2, 2018, the court granted in part and denied in part AGFP’s motion. The court dismissed, in its entirety, LBIE’s remaining claim for breach of the MASTR Adjustable Rate Mortgages Trust 2007-3 (Wells Fargo),implied covenant of good faith and fair dealing and also dismissed LBIE’s claim for breach of contract solely to the extent that it is based upon AGFP’s conduct in connection with the auction. With respect to LBIE’s claim for breach of contract, the court held that there are triable issues of fact regarding whether AGFP calculated its loss reasonably and in good faith. On October 1, 2018, AGFP filed an interpleader complaint inappeal with the U.S. DistrictAppellate Division of the Supreme Court forof the Southern DistrictState of New York, First Judicial Department, seeking adjudicationreversal of a dispute between Wales LLC (Wales) and AGM as to whether AGM is entitled to reimbursement from certain cashflows for principal claims paid in respectthe portions of insured certificates. On September 30, 2016, the court issued an opinionlower court's ruling denying aAGFP’s motion for summary judgment on the pleadings filed by Wales.with respect to LBIE’s sole remaining claim for breach of contract. On January 3, 2017,17, 2019, the Court approved a StipulationAppellate Division affirmed the Supreme Court's decision, holding that the lower court correctly determined that there are triable issues of fact regarding whether AGFP calculated its loss reasonably and Order of Dismissal of Wales from the action due to Wales having sold its interests in the MASTR Adjustable Rate Mortgages Trust 2007-3 certificates. On February 9, 2017, the remaining parties submitted a Stipulation and (Proposed) Order of Voluntary Dismissal, which the Court has not yet so-ordered. The Company estimates that an adverse outcome to the interpleader proceeding could increase losses on the transaction by approximately $10 - $20 million, net of expected settlement payments and reinsurance in force.good faith.

On December 22, 2014, Deutsche Bank National Trust Company, as indenture trustee for the AAA Trust 2007-2 Re-REMIC (the Trustee), filed a “trust instructional proceeding” petition in the State of California Superior Court (Probate Division, Orange County), seeking the court’s instruction as to how it should allocate the losses resulting from its December 2014 sale of four RMBS owned by the AAA Trust 2007-2 Re-REMIC. This sale of approximately $70 million principal balance of RMBS was made pursuant to AGC’s liquidation direction in November 2014, and resulted in approximately $27 million of gross proceeds to the Re-REMIC. On December 22, 2014, AGC directed the indenture trustee to allocate to the uninsured Class A-3 Notes the losses realized from the sale. On May 4, 2015, the Superior Court rejected AGC’s allocation

direction, and ordered the Trustee to allocate to the Class A-3 noteholders a pro rata share of the $27 million of gross proceeds. AGC is appealing the Superior Court’s decision to the California Court of Appeal.

Performance Graph

Set forth below are a line graph and a table comparing the dollar change in the cumulative total shareholder return on AGL's common shares from December 31, 20112013 through December 31, 20162018 as compared to the cumulative total return of the Standard & Poor's 500 Stock Index, and the cumulative total return of the Standard & Poor's 500 Financials Sector GICS Level 1 Index and the cumulative total return of the Russell Midcap Financial Services Index. The Company added the Russell Midcap Financial Services Index in 2018 because it believes that this index, which includes the Company, provides a useful comparison to other companies in the financial services sector, and excludes companies that are included in the Standard & Poor's 500 Financials Sector GICS Level 1 Index but are many times larger than the Company.

ITEM 7.MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the Company’s financial condition and results of operations should be read in conjunction with the Company’s consolidated financial statements and accompanying notes which appear elsewhere in this Form 10-K. It contains forward looking statements that involve risks and uncertainties. Please seeSee “Forward Looking Statements” for more information. The Company's actual results could differ materially from those anticipated in these forward looking statements as a result of various factors, including those discussed below and elsewhere in this Form 10-K, particularly under the headings “Risk Factors” and “Forward Looking Statements.”

Introduction
 
The Company provides credit protection products to the U.S. and international public finance (including infrastructure) and structured finance markets. The Company applies its credit underwriting judgment, risk management skills and capital markets experience primarily to offer financial guaranty insurance that protectscredit protection products to holders of debt instruments and other monetary obligations that protect them from defaults in scheduled payments. If an obligor defaults on a scheduled payment due on an obligation, including a scheduled principal or interestdebt service payment, the Company is required under its unconditional and irrevocable financial guaranty to pay the amount of the shortfall to the holder of the obligation. The Company markets its financial guaranty insurancecredit protection products directly to issuers and underwriters of public finance and structured finance securities as well as to investors in such obligations. The Company guarantees obligations issued principally in the U.S. and the U.K., and also guarantees obligations issued in other countries and regions, including Australia and Western Europe. The Company also provides other forms of insurance that are in lineconsistent with its risk profile and benefit from its underwriting experience.

Executive Summary
  
This executive summary of management’s discussion and analysis highlights selected information and may not contain all of the information that is important to readers of this Annual Report. For a more detailed description of events, trends and uncertainties, as well as the capital, liquidity, credit, operational and market risks and the critical accounting policies and estimates affecting the Company, this Annual Report should be read in its entirety.

Economic Environment
 
The amount and pricing of new business the Company originates, as well as the financial health of the issuers whose obligations it insures, dependU.S. has experienced sustained positive economic momentum in part on the economic environment in the markets it serves, including the level of interest rates and credit spreads in those markets.

The overall U.S. economic environment continued improving during 2016. The U.S. Department of Commerce Bureau of Economic Analysis reported an advanced estimate that real gross domestic product increased 1.6% during 2016.2018. According to the U.S. Bureau of Labor Statistics (BLS), the U.S. economy added an estimatedunemployment rate began the year at 4.1% and ended the year at 3.9%. Payroll employment growth in 2018 totaled 2.6 million jobs, compared with a gain of 2.2 million jobs during 2016, andin 2017. Gross domestic product (GDP) increased 2.9% in 2018, compared with 2.2% in 2017 according to the estimated monthly unemployment rate did not exceed 5.0% in any monthBureau of the year, falling in the fourth quarter to levels not seen since 2007. Federal Reserve Board Chairman Janet Yellen stated in January 2017 that labor utilization was close to a normal level and other measures of labor utilization had improved appreciably.Economic Analysis initial estimate.

TheAs reported by U.S. stock market trended higher during 2016 in response to continuing signs of economic improvement, although investors experienced considerable volatility related to oil prices, global economic uncertainty, and political developments such as the British electorate's vote in favor of Britain exiting the European Union (Brexit)Census Bureau and the U.S. presidential election. Stock market indices rose to record levels in the fourth quarter.

Department of Housing and Urban Development, U.S. home prices as measured bymoderated during 2018 while remaining historically high. The median sale price of new homes sold in the S&P CoreLogic Case-Shiller U.S. National Home Price Index, continuedfell to rise at$302,400 in November 2018, the lowest level recorded since February 2017 and 11.9% below the peak value of $343,400 recorded in November 2017. Falling median new home prices and rising median household incomes have contributed to an improvement in the relative affordability of new homes sold in the U.S. See Item 8, Financial Statements and Supplementary Data, Note 5, Expected Loss to be Paid, for a 5.6% rate overdiscussion of the 12 months ended November 30, 2016.market assumptions used in determining expected losses for U.S. RMBS.

FromAt the beginning ofDecember 2018 FOMC meeting, the year, the Federal Open Market Committee (FOMC) supported further improvement in labor market conditions and a return to 2% inflation. It maintainedFOMC raised the target range for the federal funds rate at 1/4 to 1/2 percent until mid-December, whenbetween 2.25% and 2.5%, its fourth rate hike of 2018. The federal funds rate ended 2017 with a target range of 1.25% and 1.50%. On January 30, 2019, the FOMC made the following statement in regards to future rate hikes in 2019, softening its tone from the December meeting: “In light of global economic and financial developments and muted inflation pressures, the Committee will be patient as it raised itdetermines what future adjustments to the target range for the federal funds rate may be appropriate to support these outcomes.” The Company believes this signaled a quarter pointlevel of cautiousness in 2019 and a wait-and-see approach as to 1/2 to 3/4 percent and projected three additional increases during 2017. whether there would be rate hikes in 2019.

Average municipal interest rates were extremely lowin 2018 remained above the historic lows experienced in 2016, during the year, with thewhich 30-year AAA MMD Index fallingrates were at times below 2%. The 30-year AAA MMD rate started the year off at 2.54% and increased to as high as 3.46% in early November 2018. The 30-year AAA MMD rate ended the year at 3.02%. Credit spreads remained largely unchanged throughout 2018 at relatively narrow levels. At year-end, the spread between the MMD “A” general obligation 20-year index and the MMD “AAA” general obligation 20-year index was 50 basis points (bps), having started the year off at 48 bps. During 2018, the spread average was 50.1 bps, more than 5 bps tighter than the 55.7 bps average in 2017.


When interest rates are low, or when the market is relatively less risk averse, the credit spread between high-quality or insured obligations versus lower- rated or uninsured obligations typically narrows. As a threshold not previously crossedresult, financial guaranty insurance typically provides lower interest cost savings to issuers than it would during periods of relatively wider credit spreads. Issuers are less likely to use financial guaranties on their new issues when credit spreads are narrow, which results in decreased demand or premiums obtainable for financial guaranty insurance, and a resulting reduction in the modern era. The low rates helped produce record issuanceCompany's results of operations. See Key Business Strategies, New Business Productionsection below for market volume and penetration.

Equity markets continued their solid 2017 performance during the first three quarters of 2018, but turned decidedly lower in the fourth quarter. The Company believes that fears that an increasing interest rate environment would hurt the economy in the medium-term, the potential impact of trade negotiations with China, European turmoil (i.e. Brexit; Italy's political, economic, and sovereign fiscal instability), and the partial U.S. municipal bondgovernment shut down increased market while constrainingvolatility and sent the opportunitiesmajor U.S. indices lower for bond insurersthe year. The Dow Jones Industrial Average (DJIA), Nasdaq Composite Index and the S&P 500 Index all finished in negative territory for the full year.

During 2018 the U.S. dollar appreciated by around 8% against other currencies on a trade-weighted basis according to add financial value.data from the Federal Reserve Bank of St. Louis. The Company believes this was the result of the U.S. economy's stronger economic performance vis-à-vis the rest of the world and the differing monetary policy path pursued by the Federal Reserve and other key central banks like the Bank of Japan, the Bank of England and the European Central Bank.

Several primary drivers of volatility in net income or loss are not necessarily indicative of credit impairment or improvement, or ultimate economic gains or losses:losses such as: changes in credit spreads of insured credit derivative obligations;obligations, changes in fair value of assets and liabilities of financial guaranty variable interest entities (FG VIEs)FG VIEs and committed capital securities (CCS);, changes in fair value of credit derivatives related to the Company's own credit spreads;spreads, and changes in risk-free rates used to discount expected losses. Changes in the Company's and/or collateral credit spreads generally have the most significant effect on the fair value of credit derivatives and FG VIEVIEs’ assets and liabilities. Effective January 1, 2018, the change in fair value of FG VIEs’ liabilities with recourse attributed to changes in the credit spreads of AGC and AGM, or instrument specific credit risk (ISCR), is recorded in OCI. 


In addition to non-economic factors, other factors such as: changes in expected losses,claims and recoveries, the amount and timing of the refunding transactions and terminations,and/or termination of insured obligations, realized gains and losses on the investment portfolio (including other-than-temporary impairments)impairments (OTTI)), the effects of large settlements, and transactions,commutations, acquisitions, and the effects of the Company's various loss mitigation strategies, and changes in laws and regulations, among others, may also have a significant effect on reported net income or loss in a given reporting period.

Key Business Strategies

The Company continually evaluates its business strategies. Currently, the Company is pursuing the following business strategies, each described in more detail below:

New business production
Capital management
Alternative strategies to create value, including through acquisitions, investments and commutations
Loss mitigation

New Business Production

The Company believes high-profile defaults by municipal obligors, such as the Commonwealth of Puerto Rico, Detroit, Michigan and Stockton, California have led to increased awareness of the value of bond insurance and stimulated demand for the product. The Company believes there will be continued demand for its insurance in this market because, for those exposures that the Company guarantees, it undertakes the tasks of credit selection, analysis, negotiation of terms, surveillance and, if necessary, loss mitigation. The Company believes that its insurance:

encourages retail investors, who typically have fewer resources than the Company for analyzing municipal bonds, to purchase such bonds;
enables institutional investors to operate more efficiently; and
allows smaller, less well-known issuers to gain market access on a more cost-effective basis.

On the other hand, the persistently low interest rate environment hasand relatively tight U.S. municipal credit spreads have dampened demand for bond insurance, and afterprovisions in legislation known as the Tax Act, such as the termination of the tax-exempt status of advance refunding bonds and the reduction in corporate tax rates, have resulted in a numberreduction of years in which the Company was essentially the only financial guarantor, there are now two other financial guarantors active in one of its markets.supply and made municipal obligations less attractive to certain institutional investors.

Excluding the year ended December 31, 2016 compared with the year ended December 31, 2015, PVP increased by approximately 20% to $214 million, primarily due to an increase in secondary marketassumed business from SGI, U.S. public finance PVP was 5% higher compared with 2017, despite a 22% decline in new business.

In 2018 this included several infrastructure finance business generally represents European infrastructure transactions. The Company believesand regulated utilities transactions, including the U.K. currently presents the most new business opportunities for financial guarantees of infrastructure financings, which have typically required such guarantees for capital market access. These transactions typically have long lead times. The Company believes it is the only companyCompany's first post-financial crisis transaction in the private sector offering such financial guarantees outside the United States.Australia.

In non-U.S. structured finance, the Company closed insurance and reinsurance aircraft residual value insurance policies, which represented all of the new business in 2017 and the majority of new business in 2018. In 2018, the Company also closed transactions in the commercial real estate market, and guaranteed a collateralized loan obligation for the first time since 2008. Structured finance transactions tend to have long lead times and may vary from period to period.

The Company believes its financial guaranty product is competitive with other financing options in certain segments of the global infrastructure market.  Future business activity in the global infrastructure market will be influenced by the typically long lead times for these types of transactions and may vary from period In general,to period.

The Company considers its involvement in both international infrastructure and structured finance and international infrastructure transactions to be beneficial because such transactions diversify both the Company's business opportunities and its risk profile beyond U.S. public finance. This category also includes a structured capital relief Triple-X excess of loss life reinsurance transaction.

The difference between GWP and PVP relates primarily to the difference in discount rates used in the calculation of PVP compared with GWP and the inclusion in GWP of the effects of changes in lives of the existing insured portfolio.


Capital Management
    
In recent years, the Company has developed strategies to manage capital within the Assured Guaranty group more efficiently.

In 2016, AGM sought and received approval from the NYDFS to repurchase $300 million of its common stock from its parent, Assured Guaranty Municipal Holdings Inc. (AGMH). The repurchase was effectuated on December 19, 2016. Subsequently, AGMH distributed the proceeds as dividends to its immediate parent, AGUS, and in 2017, AGUS began using these proceeds to pay dividends to AGL. AGL intends to use these funds predominantly to repurchase its publicly traded common shares. AGM and AGC have also been paying dividends to their parents, and MAC may also pay dividends to its parents. See Part II, Item 8, Financial Statements and Supplementary Data, Note 11, Insurance Company Regulatory Requirements for additional information about dividends the Company's insurance companies may and have paid.

In 2014, AGUS issued 5.0% Senior Notes for net proceeds of $495 million. The net proceeds from the sale of the notes were used for general corporate purposes, including the repurchase of common shares of AGL.

From 2013 through February 23, 2017,March 1, 2019, the Company has repurchased a total of 72.295.7 million common shares for approximately $1,857$2,764 million, excluding commissions.representing 49% of the total shares outstanding at the beginning of the repurchase program in 2013. On February 22, 201727, 2019, the Board of Directors (the Board) authorized an additional $300 million inof share repurchases. As of February 23, 2017, $407March 1, 2019, $350 million of authority remainsremained under the Company'saggregate share repurchase authorizations. The Company expects the repurchases toauthorization. Shares may be maderepurchased from time to time in the open market or in privately negotiated transactions. The timing, form and amount of the share repurchases under the program are at the discretion of management and will depend on a variety of factors, including free funds available at the parent company, other potential uses for such free funds, market conditions, the Company's capital position, legal requirements and other factors. The repurchase program may be modified, extended or terminated by the Board of Directors at any time. Ittime and does not have an expiration date.

(1)Cumulative repurchases since the beginning of 2013.


In 2017, the respective regulators of AGC, AGM and MAC approved those companies' repurchases of shares of common stock from their respective direct parent companies. AGC implemented a $200 million share repurchase in January 2018, AGM implemented a $101 million share repurchase in December 2017 and MAC implemented a $250 million share repurchase in September 2017. AGL has used these funds predominantly to repurchase its publicly traded common shares.

In orderDecember 2016, AGM repurchased $300 million of its common stock from AGMH, the majority of which was ultimately distributed to reduce leverage,AGL. AGL has used these funds predominantly to repurchase its publicly traded common shares. In June 2016, MAC repaid its $300 million surplus note to Municipal Assurance Holdings Inc. (MAC Holdings) and possibly rating agency capital charges,its $100 million surplus note (plus accrued interest) to AGM with a mixture of cash and/ or marketable securities. MAC Holdings, in turn, distributed $182 million to AGM and $118 million to AGC. See Item 8, Financial Statements and Supplementary Data, Note 11, Insurance Company Regulatory Requirements, for information about dividend capacity of the Company has mutually agreed with beneficiaries to terminate selected financial guarantyCompany's insurance and credit derivative contracts. In particular, the Company has targeted investment grade securities for which claims are not expected but which carry a disproportionately large rating agency capital charge. companies.

The Company terminated investment grade financial guarantyalso considers the appropriate mix of debt and CDS contracts with netequity in its capital structure, and may repurchase some of its debt from time to time. For example, in 2018 and 2017, AGUS purchased $100 million and $28 million of par, respectively, of $6.6 billionAGMH's outstanding Junior Subordinated Debentures, which resulted in 2016, $2.8 billiona loss on extinguishment of debt of $34 million in 20152018 and $3.1 billion$9 million in 2014.2017. The Company may choose to make additional purchases of this or other Company debt in the future.


Alternative Strategies

The Company considers alternative strategies in order to create long-term shareholder value.value, including acquisitions, investments and commutations. For example, the Company considers opportunities to acquire financial guaranty portfolios, whether by acquiring financial guarantors who are no longer actively writing new business or their insured portfolios, or by commuting business that it had previously ceded.ceded business. See New Business Production above, and Item 8, Financial Statements and Supplementary Data, Note 2, Assumption of Insured Portfolio and Business Combinations, and Item 8, Financial Statements and Supplementary Data, Note 13, Reinsurance, for additional information. These transactions enable the Company to improve its future earnings and deploy some of its excess capital. During 2016, the Company established an alternative investments group to focus on deploying a portion of the Company's excess capital to pursue acquisitions and develop new business opportunities that complement the Company's financial guaranty business, are in line with its risk profile and benefit from its core competencies.

CIFG Holding Inc.Assumption of Insured Portfolio. On June 1, 2018, the Company closed the SGI Transaction under which AGC assumed, generally on a 100% quota share basis, substantially all of SGI’s insured portfolio and AGM reassumed a book of business previously ceded to SGI by AGM. The net par value of exposures reinsured and commuted as of June 1, 2018 totaled approximately $12 billion. The SGI Transaction reduced shareholders' equity by $0.16 per share, due to a loss on the reassumed book of business, and increased non-GAAP adjusted book value by $2.25 per share. Additionally, beginning on June 1, 2018, on behalf of SGI, AGC began providing certain administrative services on the assumed portfolio, including surveillance, risk management, and claims processing.

Acquisitions: On January 10, 2017, AGC completed its acquisition of MBIA UK, which added a total of $12 billion in net par. At acquisition, MBIA UK contributed shareholders' equity of $84 million and non-GAAP adjusted book value of $322 million.     On July 1, 2016, AGC acquired all of the issued and outstanding capital stock of CIFGH, for $450.6 million in cash. AGUS previously owned 1.6% of the outstanding shares of CIFGH, for which it received $7.1 million in consideration from AGC, resulting in a net consolidated purchase price of $443 million. AGC merged CIFGNA with and into AGC, with AGC as the surviving company, on July 5, 2016. The CIFG Acquisition added $4.2 billion of net par insured on July 1, 2016. In 2016, the acquisitioncash that contributed net income and operating income of approximately $2.41$2.23 per share and $2.38to shareholders' equity, $2.23 per share respectively, including the bargain purchase gain, loss on settlement of pre-existing relationships and activity since the the date of the CIFG Acquisition (CIFG Acquisition Date). Shareholders' equity benefited by $2.23 per share,to non-GAAP operating shareholders' equity benefited by $2.23and $3.85 per share andto non-GAAP adjusted book value benefited by $3.85 per share asat the date of the CIFG Acquisition Date.acquisition.

Radian Asset Assurance Inc.Commutations. On April 1, 2015 (the Radian Acquisition Date), AGC completed the acquisition of Radian Asset for a cash purchase price of $804.5 million. In connection with the acquisition, AGC acquired Radian Asset’s entire insured portfolio, whichThe Company entered into various commutation agreements to reassume previously ceded business in 2018, 2017 and 2016 that resulted in an increase in net par outstanding aslosses of the Radian Acquisition Date of approximately $13.6 billion, consisting of $9.4 billion of public finance net par outstanding and $4.2 billion of structured finance net par outstanding. In 2015, the acquisition contributed net income of approximately $2.46 per share and operating income of approximately $2.13 per share, including the bargain purchase gain, settlement of pre-existing relationships and activity since the Radian Acquisition Date. Shareholders' equity benefited by $1.04 per share, non-GAAP operating shareholders' equity benefited by $1.26 per share and non-GAAP adjusted book value benefited by $3.73 per share as of the Radian Acquisition Date.

MBIA UK Insurance Limited.On January 10, 2017, AGC completed its acquisition of MBIA UK Insurance Limited (MBIA UK), the European operating subsidiary of MBIA. As consideration for the outstanding shares of MBIA UK plus $23$16 million in cash, AGC exchanged all2018, gains of $328 million in 2017 and gains of $8 million in 2016. The commutations added net unearned premium reserve of $64 million in 2018 and $82 million in 2017. In the future, the Company may enter into new commutation agreements to reassume portions of its holdingsinsured business ceded to other reinsurers, but such opportunities are expected to be limited given the small number of notes issued inunaffiliated reinsurers currently reinsuring the Zohar II 2005-1 transaction. AGC’s Zohar II 2005-1 notes had a total outstanding principal of approximately $347 million and fair value of $334 million as of the date of acquisition. MBIA insured all of the notes issued in the Zohar II 2005-1 transaction. As of December 31, 2016, MBIA UK had an insured portfolio of approximately $12 billion of net par. MBIA UK has changed its name to Assured Guaranty (London) Ltd. (AGLN). Assured Guaranty currently maintains AGLN as a stand-alone entity. Assured Guaranty is actively working to combine AGLN with its other affiliated European insurance companies. Any such combination will be subject to regulatory and court approvals; as a result, Assured Guaranty cannot predict when, or if, such a combination will be completed.Company.

Alternative Investments. The alternative investments group has been investigating a number of new business opportunities that complement the Company's financial guaranty business, are in line with its risk profile and benefit from its core competencies, including, among others, both controlling and non-controlling investments in investment managers.

In February 2018, the Company acquired a minority interest in the holding company of Rubicon Infrastructure Advisors, a full-service investment firm based in Dublin that provides investment banking services within the global infrastructure sector. In September 2017, the Company acquired a minority interest in Wasmer, Schroeder & Company LLC, an independent investment advisory firm specializing in SMAs. In February 2017 the Company agreed to purchase up to $100 million of limited partnership interests in a fund that invests in the equity of private equity managers. managers of which $83 million remains to be invested as of December 31, 2018.

The Company continues to investigate additional opportunities.opportunities, but there can be no assurance of whether or when the Company will find suitable opportunities on appropriate terms.

Commutations. The Company entered into various commutation agreements to reassume previously ceded business in 2016, 2015 and 2014 that resulted in gains of $8 million in 2016, $28 million in 2015 and $23 million in 2014 and additional net unearned premium reserve of $0 in 2016, $23 million in 2015 and $20 million in 2014. The commutation gains were recorded in other income. The Company may also in the future enter into new commutation agreements reassuming portions of its remaining previously ceded business.

Loss Mitigation
    
In an effort to avoid or reduce potential losses in its insurance portfolios, the Company employs a number of strategies.
    
In the public finance area, the Company believes that its experience and the resources it is prepared to deploy, as well as its ability to provide bond insurance or other contributions as part of a solution, has resultedresult in more favorable outcomes in distressed public finance situations than would have beenbe the case without its participation, asparticipation. This has been illustrated for example, by the Company's role in the Detroit, Michigan; Stockton, California; and Jefferson County, Alabama financial crises. Currently, the Company is an active participantactively working to mitigate potential losses in discussionsconnection with the obligations it insures of the Commonwealth of Puerto Rico and various obligations of its advisors with respectrelated authorities and public corporations and was an active participant in negotiating the Puerto Rico Sales Tax Financing Corporation (COFINA) Plan of Adjustment. The Company will also, where appropriate, pursue litigation to enforce its rights, and it has initiated a number of legal actions to enforce its rights in Puerto Rico. For more information about developments in Puerto Rico credits. For example, on December 24, 2015, AGC and AGM entered into a Restructuring Support Agreement (RSA) with Puerto Rico Electric Power Authority (PREPA), an ad hoc group of uninsured bondholders and a group of fuel-line lenders that would, subject to certain conditions, result in, among other things, modernization of the utility and a restructuring of current debt. Legislation meeting the requirements of the RSA was enacted on February 16, 2016, and a transition charge to be paid by PREPA rate payers for debt service on the securitization bonds as contemplatedrelated recovery litigation being pursued by the RSA was approved by the Puerto Rico Energy Commission on June 20, 2016. The closing of the restructuring transactionCompany, see Item 8, Financial Statements and the issuance of the surety bonds are subject to certain conditions, including execution of acceptable documentation and legal opinions. There can be no assurance that the conditions in the RSA will be met or that, if the conditions are met, the RSA's other provisions, including those related to the restructuring of the insured PREPA revenue bonds, will be implemented as currently agreed. In addition, there also can be no assurance that the negotiations with respect to other Puerto Rico credits will result in agreements on a consensual recovery plans.Supplementary Data, Note 4, Outstanding Exposure.

The Company is currently working with the servicers of some of the RMBS it insures to encourage the servicers to provide alternatives to distressed borrowers that will encourage them to continue making payments on their loans and soto help improve the performance of the related RMBS. Many of the home equity lines of credit (HELOC) loans underlying the HELOC RMBS have entered or are entering their amortization periods, which results in material increases to the size of the monthly payments the borrowers are required to make.

The Company also continues to purchase attractively priced obligations, including BIG obligations, that it has insured and for which it has expected losses to be paid, in order to mitigate the economic effect of insured losses (loss mitigation securities). The fair value of assets purchased for loss mitigation purposes as of December 31, 2016 (excluding the value of the Company's insurance) was $1,299 million, with a par of $2,243 million (including bonds related to FG VIEs of $49 million in fair value and $236 million in par).

In some instances, the terms of the Company's policy gives it the option to pay principal on an accelerated basis on an obligation on which it has paid a claim, thereby reducing the amount of guaranteed interest due in the future. The Company has at times exercised this option, which uses cash but reduces projected future losses.

In an effort to recover losses The Company may also facilitate the Company experienced in its insured U.S. RMBS portfolio,issuance of refunding bonds, by either providing insurance on the Company also continues to pursue providers of representations and warranties (R&W) by enforcing R&W provisions in contracts, negotiating agreementsrefunding bonds or purchasing refunding bonds, or both. Refunding bonds may provide the issuer with R&W providers relating to those provisions and, where appropriate, pursuing litigation against R&W providers. See Part II, Item 8, Financial Statements and Supplementary Data, Note 5, Expected Loss to be Paid.payment relief.

Other Events

Brexit

The Company is evaluating the impact on its business of theOn June 23, 2016, a referendum was held in the U.K on June 23, 2016,U.K. in which a majority voted to exit the EU, known as “Brexit”. Negotiations areThe U.K. government served notice to the European Council on March 29, 2017 of its desire to withdraw in accordance with Article 50 of the Treaty on European Union. As described above in Part 1, Item 1, Business, Regulation, there has been no approval by the U.K. parliament of any withdrawal agreement between the EU and the U.K. Failing such approval or the implementation of an agreed extension to the U.K.'s planned departure date, the U.K. is currently expected to commence soonleave the EU on March 29, 2019 under a No-Deal Brexit, leaving considerable uncertainty as to determine the futureongoing terms of the U.K’s relationship with the EU, including the terms of trade between the U.K. and the EU. The negotiations, once commenced, areEU, and a likely to last for two years, or possibly more.negative impact on all parties. Given the lack of clarity on the ultimate post-Brexit relationship between the U.K. and the EU, the Company cannot fully determine what, if any, impact Brexit may impact laws, ruleshave on its business or operations, both inside and regulations applicable tooutside the Company’s U.K. subsidiaries and U.K. operations.

The Company cannot predict the direction Brexit-related developments will take nor the impact of those developments on the economies of the markets the Company serves, which may materially adversely affect the Company’s business, results of operations and financial condition,, but the Companyit has identified certain areas where Brexit may impact its business:the following issues:


Currency Impact. The Company reports its accounts in U.S. dollars, while some of its income, expenses, assets and liabilities are denominated in other currencies, primarily the pound sterling and the euro. From December 31,

2015 to December 31,During 2016, the year in which a majority in the U.K. voted for Brexit, the value of pound sterling dropped from £0.68 per dollar to £0.81 per dollar, while the euro dropped from €0.83 per dollar to €0.95 per dollar. For the year ended 2016 the Company recognized losses of approximately $21 million in the consolidated statement of operations, net of tax, and approximately $32 million in OCI, net of tax, for foreign currency translation, that were primarily driven by the exchange rate fluctuations of the pound sterling. IfCurrency exchange rates may also move materially as the Company had owned AGLN during 2016, these impacts would have been greater.terms of Brexit become known, especially in the event of a No-Deal Brexit.

U.K. Business. As of December 31, 2016,2018, approximately $15.9$31.1 billion of the Company’s insured net par is to risks located in the U.K., and most of that exposure is to utilities, with much of the rest to hospital facilities, government accommodation, universities, toll roads government accommodation,and housing associations universities and other public purpose enterprises that the Company believes are not overly vulnerable to Brexit pressures. AGE is currently authorized by the PRA of the Bank of England with permissions sufficient to enable AGE to effect and carry out financial guaranty insurance and reinsurance in the U.K. Most of the new transactions insured by AGE since 2008 have been in the U.K. As of December 31, 2016, approximately $10.0 billion of insured net par of AGLN, which the Company acquired in January 2017, is to risks located in the U.K.

Business Elsewhere in the EU. As of December 31, 2016,2018, approximately $5.5$7.1 billion of the Company’s insured net par is to risks located in EU and EEA countries other than the U.K. As of December 31, 2016, approximately $1.5 billion of insured net par of AGLN, which the Company acquired in January 2017, is to risks located in EU and EEA countries other than the U.K. Currently, EU directives allow AGE to conduct business in other EU or EEA states based on its PRA permissions. This is sometimes called “passporting”. Depending onThe Company cannot determine whether U.K. authorized financial services firms such as AGE will continue to enjoy passporting rights to the termsother EEA states after Brexit. This question will be particularly acute in the event of a No-Deal Brexit AGE may, once Brexitbecause the loss of passporting could occur as early as March 29, 2019, rather than at the end of the transition period under the withdrawal agreement of December 31, 2020. As a consequence, Assured Guaranty is implemented, loseestablishing a new subsidiary in Paris, France, in order to continue with the ability to insurewrite new transactions from Londonbusiness, and to service existing business, in non-U.K. EU andthose other EEA countries without obtaining additional licenses, which may require a presence in another EU country. While pertinent laws and regulations have yetstates. That new subsidiary is unlikely to be adopted or passed,fully licensed prior to a No-Deal Brexit, should that occur. While the Company believes that, in the event of a No-Deal Brexit or in the absence of applicable transition rules, those other EEA states outside the U.K. will permit the Company to continue to service existing business in their states, there can be no assurance that this will occur, nor can the Company fully determine the impact on its business and operations if it does not believe Brexit will adversely affect its surveillance and loss mitigation activities with respect to existing insured transactions in non-U.K. EU and EEA countries, except to the extent Brexit inhibits the issuance of new guaranties in distressed situations in non-U.K. EU or EEA countries.occur. As noted above, most of the new transactions insured by AGE since 2008 have been in the U.K.

While nearly one-thirdAll of the employees working in AGE’s London office are non-U.K. EUeither U.K. citizens or EEA citizens, most of those employees currently qualify, andhave U.K. resident status except one, who has started the Company expects the rest to qualify within the next two years,application process to become permanent residents under currenta U.K. law.resident.


Results of Operations
 
Estimates and Assumptions
 
The Company’s consolidated financial statements include amounts that are determined using estimates and assumptions. TheIt is possible that actual amounts realized could ultimately bediffer, possibly materially, different from the amounts currently provided forrecorded in the Company’s consolidated financial statements. Management believes the most significant items requiring inherently subjective and complex estimates are expected losses, fair value estimates, other-than-temporary impairment,OTTI, deferred income taxes, and premium revenue recognition. The following discussion of the results of operations includes information regarding the estimates and assumptions used for these items and should be read in conjunction with the notes to the Company’s consolidated financial statements.
 
An understanding of the Company’s accounting policies is of critical importance to understanding its consolidated financial statements. See Part II, Item 8, Financial Statements and Supplementary Data, for a discussion of the significant accounting policies, the loss estimation process, and the fair value methodologies.

The Company carries a significant amount of its assets and a portion of its liabilities at fair value, the majority of which are measured at fair value on a recurring basis. Level 3 assets, primarily consisting primarily of loss mitigation securities and FG VIE’VIEs’ assets, credit derivative assets and investments, represented approximately 19%18% and 20%17% of the total assets that are measured at fair value on a recurring basis as of December 31, 20162018 and 2015,2017, respectively. All of the Company's liabilities that are measured at fair value are Level 3. See Part II, Item 8, Financial Statements and Supplementary Data, Note 7, Fair Value Measurement, in for additional information about assets and liabilities classified as Level 3.information.

Net Earned Premiums

NetPremiums are earned premiums are recognized over the contractual lives, or in the case of homogeneous pools of insured obligations, the remaining expected lives, of financial guaranty insurance contracts. The Company estimates remaining expected lives of its insured obligations and makes prospective adjustments for such changes in expected lives. Scheduled net earned premiums are expected to decrease each year unless replaced by a higher amount of new business, reassumptions of previously ceded business, or books of business acquired in a business combination. See Part II, Item 8, Financial Statements and Supplementary Data, Note 6, Contracts Accounted for as Insurance, Financial Guaranty Insurance Premiums, for additional information and the expected timing of future premium earnings.information.

20162018 compared with 2015:2017: Net earned premiums increaseddecreased in 20162018 compared with 20152017 primarily due primarily to higher accelerations, partially offsetreduced refunding activity due to a reduction in the insured portfolio as well as fewer advanced refunding bonds, caused by the lower earned premiums resulting from the scheduled declinechanges in par outstanding.tax law enacted in 2017. At December 31, 2016, $3.32018, $3.5 billion of net deferred premium revenue remained to be earned over the life of the insurance contracts. The CIFGSGI Transaction contributed $375 million of net unearned premium reserve on June 1, 2018.

2017 compared with 2016: Net earned premiums decreased in 2017 compared with 2016 due to lower refundings and terminations. The MBIA UK Acquisition increased deferred premium revenue by $296$383 million at the date of the acquisition.

2015 compared with 2014: Net earned premiums increased in 2015 compared with 2014 due primarily to higher accelerations and the addition of the Radian Asset book of business, offset in part by lower earned premiums resulting from the scheduled decline in par outstanding. The Radian Asset Acquisition on April 1, 2015 increased deferred premium revenue by $549 million at the date of acquisition.

The increase in net earned premiums due to accelerations is attributable to changes in the expected lives of insured obligations driven by (a) refundings of insured obligations or (b) terminations of insured obligations either through negotiated agreements or the exercise of ourthe Company's contractual rights to make claim payments on an accelerated basis.
    
Refundings occur in the public finance market and havehad been at historically high levels in recent years primarily due primarily to the low interest rate environment, which has allowed many municipalities and other public finance issuers to refinance their debt obligations at lower rates. The premiums associated with the insured obligations of municipalities and other public finance issuers are generally received upfront when the obligations are issued and insured. When such issuers pay down insured obligations prior to their originally scheduled maturities, the Company is no longer on risk for payment defaults, and therefore accelerates the recognition of the nonrefundable unearned premiums remaining fromdeferred premium revenue remaining. Provisions in the original upfront payment.2017 Tax Act regarding the termination of the tax-exempt status of advance refunding bonds has resulted in fewer refundings in 2018 than in comparable periods in prior years.


Terminations are generally negotiated agreements with issuersbeneficiaries resulting in the extinguishment of the Company’s insurance obligation with respect to the insured obligations.obligation. Terminations are more common in the structured finance asset class, but may also occur in the public finance asset class. While each termination may have different terms, they all result in the expiration of the Company’s insurance risk, such that the Company acceleratesacceleration of the recognition of the associated unearned premiums.deferred premium revenue and the reduction of remaining premiums receivable.

Net Investment Income
 
Net investment income is a function of the yield that the Company earns on invested assetsearned and the size of the investment portfolio. The investment yield is a function of market interest rates at the time of investment as well as the type, credit quality and maturity of the invested assets.

20162018 compared with 2015:2017: Net investment income decreased compared with 2017 primarily due primarily to lower average investment balance and lower average investment yield.the accretion on the Zohar II 2005-1 notes prior to the MBIA UK Acquisition date in January 2017.

The realized gains in 2015 were due primarily to sales of securities in order to fund the purchase of Radian Asset by AGC.

Net Change in Fair Value of Credit Derivatives
Changes in the fair value of credit derivatives occur because of changes in the issuing company's own credit rating and credit spreads, collateral credit spreads, notional amounts, credit ratings of the referenced entities, expected terms, realized gains (losses) and other settlements, interest rates, and other market factors. With volatility continuing in the market, unrealized gains (losses) on credit derivatives may fluctuate significantly in future periods.

Except for net estimated credit impairments (i.e., net expected payments), the unrealized gains and losses on credit derivatives are expected to reduce to zero as the exposure approaches its maturity date. Changes in the fair value of the Company’s credit derivatives that do not reflect actual or expected claims or credit losses have no impact on the Company’s statutory claims-paying resources, rating agency capital or regulatory capital positions. Changes in expected losses in respect of contracts accounted for as credit derivatives are included in the discussion of “Economic Loss Development” below.
The impact of changes in credit spreads will vary based upon the volume, tenor, interest rates, and other market conditions at the time these fair values are determined. In addition, since each transaction has unique collateral and structural terms, the underlying change in fair value of each transaction may vary considerably. The fair value of credit derivative contracts also reflects the change in the Company’s own credit cost based on the price to purchase credit protection on AGC and AGM. The Company determines its own credit risk based on quoted CDS prices traded on the Company at each balance sheet date. Generally, a widening of credit spreads of the underlying obligations results in unrealized losses and the tightening of credit spreads of the underlying obligations results in unrealized gains. A widening of the CDS prices traded on AGC and AGM has an effect of offsetting unrealized losses that result from widening general market credit spreads, while a narrowing of the CDS prices traded on AGC and AGM has an effect of offsetting unrealized gains that result from narrowing general market credit spreads.
The valuation of the Company’s credit derivative contracts requires the use of models that contain significant, unobservable inputs, and are classified as Level 3 in the fair value hierarchy. The models used to determine fair value are primarily developed internally based on market conventions for similar transactions that the Company observed in the past. There has been very limited new issuance activity in this market over the past several years and as of December 31, 2018, market prices for the Company’s credit derivative contracts were generally not available. Inputs to the estimate of fair value include various market indices, credit spreads, the Company’s own credit spread, and estimated contractual payments. See Item 8, Financial Statements and Supplementary Data, Note 7, Fair Value Measurement, for additional information.

During 2018, unrealized fair value gains were primarily generated by CDS terminations, run-off of CDS par and price improvements on the underlying collateral of the Company’s CDS. In addition, unrealized fair value gains were generated by the increase in credit given to the primary insurer on one of the Company's second-to-pay CDS policies during the period. The unrealized fair value gains were partially offset by unrealized fair value losses for 2014 included an other-than-temporary impairmentresulting from wider implied net spreads driven by the decreased cost to buy protection in AGC’s and AGM’s name, as the market cost of AGC’s and AGM’s credit protection decreased during the period. For those CDS transactions that waswere pricing at or above their floor levels, when the cost of purchasing CDS protection on AGC and AGM, which management refers to as the CDS spread on AGC and AGM, decreased the implied spreads that the Company would expect to receive on these transactions increased.

During 2017 and 2016, unrealized fair value gains were primarily generated by CDS terminations, run-off of net par outstanding, and price improvements on the underlying collateral of the Company’s CDS. The majority of the CDS transactions that were terminated were as a result of settlement agreements with several CDS counterparties. In 2016, the unrealized fair value gains were partially offset by unrealized losses resulting from wider implied net spreads. The wider implied net spreads were primarily a result of the decreased cost to buy protection in AGC’s and AGM’s name, as the market cost of AGC’s and AGM’s credit protection decreased significantly during the period. During 2017, the cost to buy protection in AGC’s and AGM’s name, specifically the five-year CDS spread, did not change materially during the period, and therefore did not have a material impact on the Company’s unrealized fair value gains and losses on CDS.

Management believes that the trading level of AGC’s and AGM’s credit spreads over the past several years has been due to the correlation between AGC’s and AGM’s risk profile and the current risk profile of the broader financial markets.

Financial Guaranty Variable Interest Entities
As of December 31, 2018 and 2017, the Company consolidated 31 and 32 FG VIEs, respectively. The table below presents the effects on reported GAAP income resulting from consolidating these FG VIEs and eliminating intercompany transactions. The consolidation of FG VIEs has the following effect on net income and shareholders' equity.

Changes in fair value gains (losses) on FG VIEs’ assets and liabilities are recorded in the Statement of Operations (effective January 1, 2018 the change in fair value of FG VIEs’ liabilities with recourse attributable to securitiesISCR is recorded in OCI, instead of net income - See Item 8, Financial Statements and Supplementary Data, Note 1, Business and Basis of Presentation, for additional information). Upon adoption, the Company reclassified a loss of approximately $33 million, net of tax, from retained earnings to AOCI.

Upon consolidation of a FG VIE, premiums and losses related to AGC's and AGM's insurance of FG VIEs’ liabilities with recourse and, any investment balances related to the Company’s purchase of AGC and AGM insured FG VIEs’ debt, are considered intercompany transactions and are therefore eliminated.

See Item 8, Financial Statements and Supplementary Data, Note 9, Variable Interest Entities, for additional information.

Commutation Gains (Losses)

In connection with the reassumption of previously ceded books of business, the Company recognized commutation losses of $16 million in 2018 and commutation gains of $328 million and $8 million in 2017 and 2016, respectively. The losses in 2018 related to the commutation component of the SGI Transaction. See Item 8, Financial Statements and Supplementary Data, Note 13, Reinsurance, for additional information.

Other Income (Loss)
 
Other income (loss) comprisesconsists of recurring items such as foreign exchange remeasurement gains and losses,those listed in the table below as well as ancillary fees on financial guaranty policies such as commitmentfor commitments and consent,consents, and if applicable, other revenue items on financial guaranty insurance and reinsurance contracts such as commutation gains on re-assumptions of previously ceded business, loss mitigation recoveries and certainother non-recurring items. In 2016, other income primarily comprised a benefit due to loss mitigation recoveries, offset in part by a loss on foreign exchange mainly due to the decline in the exchange rate of the pound sterling. In 2015 and 2014, other income primarily comprised a commutation gain on the reassumption of ceded books of business from certain reinsurers and benefits due to loss mitigation recoveries.

(1)Foreign exchange gains primarily relate to remeasurement of premiums receivable and are mainly due to changes in the exchange rate of the British pound sterling relative to the U.S. dollar.

(2)The Company recorded a gain on change in fair value of equity securities in 2018 related to the Company's minority interest in the parent company of TMC Bonds LLC, which it sold in third quarter of 2018.

(3)The loss on extinguishment of debt is related to AGUS' purchase of a portion of the principal amount of AGMH's outstanding Junior Subordinated Debentures. The loss represents the difference between the amount paid to purchase AGMH's debt and the carrying value of the debt, which includes the unamortized fair value adjustments that were recorded upon the acquisition of AGMH in 2009. AGUS purchased $100 million of principal amount in 2018 and $28 million in 2017.

Economic Loss Development

     The insured portfolio includes policies accounted for under three separate accounting models depending on the characteristics of the contract and the Company’s control rights. Please refer to Part II, Item 8, Financial Statements and Supplementary Data, Note 5, Expected Loss to be Paid, forFor a discussion of the assumptions and methodologies used in calculating the expected loss to be paid for all contracts. For a discussion ofcontracts, the loss estimation process and approach to projecting losses, and the measurement and recognition accounting policies under GAAP for each type of contract, see the followingNotes listed below in Part II, Item 8, Financial Statements and Supplementary Data:Data.

��Note 6 for financial guarantycontracts accounted for as insurance
Note 7 for fair value methodologies for credit derivatives and FG VIEVIEs’ assets and liabilities
Note 8 for contracts accounted for as credit derivatives and
Note 9 for consolidated FG VIEs.VIEs
    
In order to efficiently evaluate and manage the economics of the entire insured portfolio, management complies and analyzes expected loss information for all policies on a consistent basis. The discussion of losses that follows encompasses losses on all contracts in the insured portfolio regardless of accounting model, unless otherwise specified. In order to effectively evaluate and manage the economics of the entire insured portfolio, management compiles and analyzes expected loss information for all policies on a consistent basis. That is, management monitors and assigns ratings and calculates expected losses in the same manner for all its exposures. Management also considers contract specific characteristics that affect the estimates of expected loss.

The surveillance process for identifying transactions with expected losses is described in Part II, Item 8, Financial Statements and Supplementary Data, Note 5, Expected Losses to be Paid. More extensive monitoring and intervention is employed for all BIG surveillance categories, with internal credit ratings reviewed quarterly.
Net expected loss to be paid primarily consists primarily of the present value of future: expected claim and LAE payments, expected recoveries from issuers or excess spread and other collateral in the transaction structures, cessions to reinsurers, and expected recoveriesrecoveries/payables for breaches of R&W and the effects of other loss mitigation strategies. Current risk free rates are used to discount expected losses at the end of each reporting period and therefore changes in such rates from period to period affect the expected loss estimates reported. Assumptions used in the determination of the net expected loss to be paid such as delinquency, severity, and discount rates and expected time frames to recovery in the mortgage market were consistent by sector regardless of the accounting model used. The primary drivers of economic loss development are discussed below. Changes in risk free rates used to discount losses affect economic loss development, loss and LAE, and operating loss and LAE; however, the effect of changes in discount rates are not indicative of actual credit impairment or improvement in the period.

The primary differences between net economic loss development and loss and LAE are that the amount reported in the Consolidated Statements of Operations:

considers deferred premium revenue in the calculation of loss reserves and loss and LAE for financial guaranty insurance contracts,

eliminates loss and LAE related to FG VIEs and

does not include estimated losses on credit derivatives.


Loss and LAE reported in operating income (i.e. operating loss and LAE) includes losses on financial guaranty insurance contracts, other than those eliminated due to consolidation of FG VIEs, and credit derivatives.

For financial guaranty insurance contracts, the loss and LAE reported in the Consolidated Statements of Operations is generally recorded only when expected losses exceed deferred premium revenue. Therefore, the timing of loss recognition in income does not necessarily coincide with the timing of the actual credit impairment or improvement reported in net economic loss development. Transactions acquired in a business combination generally have the largest deferred premium revenue balances because of the purchase accounting adjustments made at acquisition. Therefore the largest differences between net economic loss development and loss and LAE on financial guaranty insurance contracts generally relate to these policies. See "Loss and LAE (Financial Guaranty Insurance Contracts)" below.

The Company’s agreements with R&W providers generally provide that, as the Company makes claim payments, the R&W providers reimburse it for those claims; if the Company later receives reimbursement through the transaction (for example, from excess spread), the Company repays the R&W providers. When the Company projects receiving more reimbursements in the future than it projects paying in claims on transactions covered by R&W settlement agreements, the Company will have a net R&W payable.

2018 Net Economic Loss Development

Public Finance Economic Loss Development: Public finance expected loss to be paid primarily related to U.S. exposure, which had BIG net par outstanding of $6.4 billion as of December 31, 2018 compared with $7.1 billion as of December 31, 2017. The Company projects that its total net expected loss across its troubled U.S. public finance exposures as of December 31, 2018 will be $832 million, compared with $1,157 million as of December 31, 2017. The total net expected loss for troubled U.S. public finance exposures is net of a credit for estimated future recoveries of claims already paid. At December 31, 2018 that credit was $586 million compared with $385 million at December 31, 2017. Economic loss development on U.S. exposures in 2018 was $70 million, which was primarily attributable to Puerto Rico exposures, partially offset by the release of reserves on the Company's exposure to the City of Hartford following the State of Connecticut's (CT) agreement to pay the debt service costs of certain bonds of the City of Hartford, including those insured by the Company.
The economic benefit of approximately $14 million on non-U.S. exposures during 2018 was mainly attributable to the U.K. arterial road and changes in certain probability of default assumptions. See Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure, for details about significant developments that have taken place in Puerto Rico.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS of $69 million was mainly related to improvement in the performance of second lien U.S. RMBS transactions. The net expected loss to be paid for U.S RMBS increased from 2017 to 2018 mainly due to the SGI Transaction and collection of a large R&W settlement in 2018.

Other Structured Finance Economic Loss Development: The economic loss development attributable to structured finance, excluding U.S. RMBS, was $8 million, related to progress on efforts to workout triple-X life insurance transactions and LAE.

2017 Net Economic Loss Development

Public Finance Economic Loss Development: Public finance expected loss to be paid primarily related to U.S. exposures which had BIG net par outstanding of $7.1 billion as of December 31, 2017 compared with $7.4 billion as of December 31, 2016. The Company projected that its total net expected loss across its troubled U.S. public finance exposures as of December 31, 2017 would be $1,157 million, compared with $871 million as of December 31, 2016. Economic loss development on U.S. exposures in 2017 was $554 million, which was primarily attributable to Puerto Rico exposures.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS was $181 million and was mainly related to an R&W litigation settlement, and improved second lien U.S. RMBS recoveries.

Other Structured Finance Economic Loss Development: The net benefit attributable to structured finance (excluding U.S. RMBS) was $55 million, primarily due to a benefit from a litigation settlement related to two triple-X transactions.

2016 Net Economic Loss Development

The total economic loss development of $139 million in 2016 was primarily related to the public finance sector, offset in part by improvements in the structured finance sector. The risk-free rates used to discount expected losses ranged from 0.0% to 3.23% as of December 31, 2016 and 0.0% to 3.25% as of December 31, 2015. The effect of changes in the risk-free rates used to discount expected losses was a benefit of $15 million in 2016.

U.S. Public Finance Economic Loss Development: Expected loss to be paid for public finance primarily related the Company's to U.S. exposures. The net par outstanding for U.S. public finance obligations rated BIG by the Company was $7.4 billion as of December 31, 2016 compared with $7.8 billion as of December 31, 2015. The Company projectsprojected that its total net expected loss across its troubled U.S. public finance creditsexposures as of December 31, 2016 willwould be $871 million, compared with $771 million as of December 31, 2015. Economic loss development on U.S. exposures in 2016 was $276 million, which was primarily attributable to Puerto Rico exposures. See "Insured Portfolio-Exposure to Puerto Rico" below for details about significant developments that have taken place in Puerto Rico.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS was $91 million and was
mainly due mainly to the acceleration of claim payments as a means of mitigating future losses on certain Alt-A transactions.

Other Structured Finance Economic Loss Development: The net benefit attributable to structured finance, (excluding excluding
U.S. RMBS)RMBS, was $39 million, primarily due primarily to a benefit from the purchase of a portion of an insured obligation as part of a loss
mitigation strategy and and the commutation of certain assumed student loan exposures.

2015 Net Economic Loss Development

Total economic loss development was $319 million in 2015, due primarily to higher U.S. public finance losses on Puerto Rico exposures, partially offset by a net benefit in the U.S. RMBS sector. The risk-free rates used to discount expected losses ranged from 0.0% to 3.25% as of December 31, 2015 compared with 0.0% to 2.95% as of December 31, 2014. The change in the risk-free rates used to discount expected losses was a benefit of $23 million in 2015.

U.S. Public Finance Economic Loss Development: The net par outstanding for U.S. public finance obligations rated BIG by the Company was $7.8 billion as of December 31, 2015 compared with $7.9 billion as of December 31, 2014. The Company projected that its total net expected loss across its troubled U.S. public finance credits as of December 31, 2015 would be $771 million, compared with $303 million as of December 31, 2014. Economic loss development in 2015 was approximately $416 million, which was primarily attributable to certain Puerto Rico exposures.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS of $82 million was primarily due to the R&W settlements during the year and a benefit due to the acceleration of claim payments as a means of mitigating future losses on certain Alt-A transactions, which was partially offset by losses in certain second lien U.S. RMBS transactions due to rising delinquencies and collateral deterioration associated with the increase in monthly payments when their loans reach their principal amortization period.

2014 Net Economic Loss Development

Total economic loss development was a favorable $30 million in 2014, due primarily to the various U.S. RMBS R&W settlements during the year and improvements in some of the Company's insured TruPS transactions. This was partially offset by U.S. public finance losses related to Puerto Rico and Detroit and structured finance losses that resulted primarily from changes in underlying assumptions on life insurance securitization transactions and the decrease in discount rates used. The risk-free rates used to discount expected losses ranged from 0.0% to 2.95% as of December 31, 2014 compared with 0.0% to 4.44% as of December 31, 2013.

U.S. Public Finance Economic Loss Development: The net par outstanding for U.S. public finance obligations rated BIG by the Company was $7.9 billion as of December 31, 2014 compared with $9.1 billion as of December 31, 2013. The Company projected that its total net expected loss across its troubled U.S. public finance credits as of December 31, 2014 would be $303 million, compared with $264 million as of December 31, 2013. Economic loss development in 2014 was approximately $183 million, which was primarily attributable to Puerto Rico and Detroit exposures.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS of $268 million was primarily due to the R&W settlements during the year.


Loss and LAE (Financial Guaranty Insurance Contracts)
 
The primary differences between net economic loss development and the amount ofreported as loss and LAE recognized in the consolidated statements of operations are that loss and LAE: (1) considers deferred premium revenue in the calculation of loss reserves and loss and LAE for financial guaranty insurance contracts, accounted for as(2) eliminates loss and LAE related to consolidated FG VIEs and (3) does not include estimated losses on credit derivatives.

Loss and LAE reported in non-GAAP operating income (i.e., operating loss and LAE) includes losses on financial guaranty insurance is dependent on the amountcontracts (other than those eliminated due to consolidation of economic loss development discussed aboveFG VIEs), and the deferred premium revenue amortization in a given period, on a contract-by-contract basis. credit derivatives.
For these transactions,financial guaranty insurance contracts each transaction’stransaction's expected loss to be expensed net of estimated recoveries, is compared with the deferred premium revenue of that transaction. Generally, whenWhen the expected loss to be expensed exceeds the deferred premium revenue, a loss is recognized in the consolidated statements of operations for the amount of such excess. Therefore, the timing of loss recognition in income does not necessarily coincide with the timing of the actual credit impairment or improvement reported in net economic loss development. Transactions (particularly BIG transactions) acquired in a business combination or seasoned portfolios assumed from legacy financial guaranty insurers generally have the largest deferred premium revenue balances. Therefore the largest differences between net economic loss development and loss and LAE on financial guaranty insurance contracts generally relate to those policies.

The amount of loss and LAE recognized in the consolidated statements of operations for financial guaranty contracts accounted for as insurance is a function of the amount of economic loss development discussed above and the deferred premium revenue amortization in a given period, on a contract-by-contract basis.

While expected loss to be paid is an important liquidity measure that provides the present value of amounts that the Company expects to pay or recover in future periods on all contracts, expected loss to be expensed is important because it presents the Company’s projection of loss and LAE that will be recognized in future periods as deferred premium revenue amortizes into income in the Consolidated Statements of Operations for financial guaranty insurance policies. Expected loss to be paid for FG VIEs pursuant to AGC’s and AGM’s financial guaranty policies is calculated in a manner consistent with financial guaranty insurance contracts, but eliminated in consolidation under GAAP.

The following table presents the loss and LAE recorded in the consolidated statements of operations. Amounts presented are net of reinsurance.

Loss and LAE in 2016 was mainly driven by higher loss reserves on certain Puerto Rico exposures.

Loss and LAE in 2015 comprised mainly changes in loss estimates on Puerto Rico exposures, second lien U.S. RMBS transactions and Triple-X life insurance transactions. Some of the increases were partially offset by improvements in first lien U.S. RMBS and student loan transactions.

In 2014, losses and LAE primarily included higher U.S. public finance loss estimates on Puerto Rico and Detroit, and higher structured finance losses attributable to Triple-X life insurance transactions. In 2014, loss and LAE also included benefits in the U.S. RMBS portfolio due primarily to the settlement of several R&W claims. Changes in risk-free rates used to discount losses also adversely affected loss expense for long-dated transactions, however this component of loss expense does not reflect actual credit impairment or improvement in the period.

For financial guaranty contracts accounted for as insurance, the amounts reported in the GAAP financial statements may only reflect a portion of the current period’s economic loss development and may also include a portion of prior-period economic loss development. The difference between economic loss development on financial guaranty insurance contracts and loss and LAE recognized in the Consolidated Statements of Operations relates to the effect of taking deferred premium revenue into account for loss and LAE, which is not considered in economic loss development.


The following table provides a schedule of the expected timing of net expected losses to be expensed. The amount and timing of actual loss and LAE may differ from the estimates shown below due to factors such as accelerations, commutations, changes in expected lives and updates to loss estimates. This table excludes $64 million related to FG VIEs, which are eliminated in consolidation.

Net Change in Fair Value of Credit Derivatives
  
Changes in the fair value of credit derivatives occur primarily because of changes in interest rates,the issuing company's own credit rating and credit spreads, collateral credit spreads, notional amounts, credit ratings of the referenced entities, expected terms, realized gains (losses) and other settlements, and the issuing company's own credit rating and credit spreads,interest rates, and other market factors. With considerable volatility continuing in the market, unrealized gains (losses) on credit derivatives may fluctuate significantly in future periods.

Except for net estimated credit impairments (i.e., net expected payments), the unrealized gains and losses on credit derivatives are expected to reduce to zero as the exposure approaches its maturity date. Changes in the fair value of the Company’s credit derivatives that do not reflect actual or expected claims or credit losses have no impact on the Company’s statutory claims-paying resources, rating agency capital or regulatory capital positions. ExpectedChanges in expected losses to be paid in respect of contracts accounted for as credit derivatives are included in the discussion aboveof “Economic Loss Development.”Development” below.
  
The impact of changes in credit spreads will vary based upon the volume, tenor, interest rates, and other market conditions at the time these fair values are determined. In addition, since each transaction has unique collateral and structural terms, the underlying change in fair value of each transaction may vary considerably. The fair value of credit derivative contracts also reflects the change in the Company’s own credit cost based on the price to purchase credit protection on AGC and AGM. The Company determines its own credit risk based on quoted CDS prices traded on the Company at each balance sheet date. Generally, a widening of credit spreads of the underlying obligations results in unrealized losses and the tightening of credit spreads of the underlying obligations results in unrealized gains. A widening of the CDS prices traded on AGC and AGM has an effect of offsetting unrealized losses that result from widening general market credit spreads, while a narrowing of the CDS prices traded on AGC and AGM has an effect of offsetting unrealized gains that result from narrowing general market credit spreads.
 
The valuation of the Company’s credit derivative contracts requires the use of models that contain significant, unobservable inputs, and are classified as Level 3 in the fair value hierarchy. The models used to determine fair value are primarily developed internally based on market conventions for similar transactions that the Company observed in the past.

There has been very limited new issuance activity in this market over the past several years and as of December 31, 2016,2018, market prices for the Company’s credit derivative contracts were generally not available. Inputs to the estimate of fair value include various market indices, credit spreads, the Company’s own credit spread, and estimated contractual payments.

Net credit derivative premiums included in the realized gains on credit derivatives line in the table above have declined in 2018, 2017 and 2016 primarily due to the decline in the net par outstanding. In recent years, the Company has negotiated terminations of investment grade and BIG CDS contracts with its counterparties. The following table presents the effects of terminations.

During 2018, unrealized fair value gains were primarily generated by CDS terminations, run-off of CDS par and price improvements on the underlying collateral of the Company’s CDS. In addition, unrealized fair value gains were generated by the increase in credit given to the primary insurer on one of the Company's second-to-pay CDS policies during the period. The unrealized fair value gains were partially offset by unrealized fair value losses resulting from wider implied net spreads driven by the decreased cost to buy protection in AGC’s and AGM’s name, as the market cost of AGC’s and AGM’s credit protection decreased during the period. For those CDS transactions that were pricing at or above their floor levels, when the cost of purchasing CDS protection on AGC and AGM, which management refers to as the CDS spread on AGC and AGM, decreased the implied spreads that the Company would expect to receive on these transactions increased.

During 2017 and 2016, unrealized fair value gains were primarily generated by CDS terminations, run-off of net par outstanding, and price improvements on the underlying collateral of the Company’s CDS. The majority of the CDS transactions that were terminated were as a result of settlement agreements with several CDS counterparties. In 2016, the unrealized fair value gains were partially offset by unrealized losses resulting from wider implied net spreads. The wider implied net spreads were primarily a result of the decreased cost to buy protection in AGC’s and AGM’s name, as the market cost of AGC’s and AGM’s credit protection decreased significantly during the period. During 2017, the cost to buy protection in AGC’s and AGM’s name, specifically the five-year CDS spread, did not change materially during the period, and therefore did not have a material impact on the Company’s unrealized fair value gains and losses on CDS.

Management believes that the trading level of AGC’s and AGM’s credit spreads over the past several years has been due to the correlation between AGC’s and AGM’s risk profile and the current risk profile of the broader financial markets.

Financial Guaranty Variable Interest Entities
As of December 31, 2018 and 2017, the Company consolidated 31 and 32 FG VIEs, respectively. The table below presents the effects on reported GAAP income resulting from consolidating these FG VIEs and eliminating intercompany transactions. The consolidation of FG VIEs has the following effect on net income and shareholders' equity.

Changes in fair value gains (losses) on FG VIEs’ assets and liabilities are recorded in the Statement of Operations (effective January 1, 2018 the change in fair value of FG VIEs’ liabilities with recourse attributable to ISCR is recorded in OCI, instead of net income - See Item 8, Financial Statements and Supplementary Data, Note 1, Business and Basis of Presentation, for additional information). Upon adoption, the Company reclassified a loss of approximately $33 million, net of tax, from retained earnings to AOCI.

Upon consolidation of a FG VIE, premiums and losses related to AGC's and AGM's insurance of FG VIEs’ liabilities with recourse and, any investment balances related to the Company’s purchase of AGC and AGM insured FG VIEs’ debt, are considered intercompany transactions and are therefore eliminated.

See Item 8, Financial Statements and Supplementary Data, Note 9, Variable Interest Entities, for additional information.

(2)The Company recorded a gain on change in fair value of equity securities in 2018 related to the Company's minority interest in the parent company of TMC Bonds LLC, which it sold in third quarter of 2018.

(3)The loss on extinguishment of debt is related to AGUS' purchase of a portion of the principal amount of AGMH's outstanding Junior Subordinated Debentures. The loss represents the difference between the amount paid to purchase AGMH's debt and the carrying value of the debt, which includes the unamortized fair value adjustments that were recorded upon the acquisition of AGMH in 2009. AGUS purchased $100 million of principal amount in 2018 and $28 million in 2017.

Economic Loss Development

     The insured portfolio includes policies accounted for under three separate accounting models depending on the characteristics of the contract and the Company’s control rights. For a discussion of assumptions and methodologies used in calculating the expected loss to be paid for all contracts, the loss estimation process and approach to projecting losses, and the measurement and recognition accounting policies under GAAP for each type of contract, see the Notes listed below in Item 8, Financial Statements and Supplementary Data.

Note 5 for expected loss to be paid
Note 6 for contracts accounted for as insurance
Note 7 for fair value methodologies for credit derivatives and FG VIEs’ assets and liabilities
Note 8 for contracts accounted for as credit derivatives
Note 9 for FG VIEs
In order to efficiently evaluate and manage the economics of the entire insured portfolio, management complies and analyzes expected loss information for all policies on a consistent basis. The discussion of losses that follows encompasses losses on all contracts in the insured portfolio regardless of accounting model, unless otherwise specified. Net expected loss to be paid primarily consists of the present value of future: expected claim and LAE payments, expected recoveries from issuers or excess spread and other collateral in the transaction structures, cessions to reinsurers, and expected recoveries/payables for breaches of R&W and the effects of other loss mitigation strategies. Current risk free rates are used to discount expected losses at the end of each reporting period and therefore changes in such rates from period to period affect the expected loss estimates reported. Assumptions used in the determination of the net expected loss to be paid such as delinquency, severity, and discount rates and expected time frames to recovery were consistent by sector regardless of the accounting model used. The primary drivers of economic loss development are discussed below. Changes in risk free rates used to discount losses affect economic loss development, and loss and LAE; however, the effect of changes in discount rates are not indicative of actual credit impairment or improvement in the period.

2018 Net Economic Loss Development

Public Finance Economic Loss Development: Public finance expected loss to be paid primarily related to U.S. exposure, which had BIG net par outstanding of $6.4 billion as of December 31, 2018 compared with $7.1 billion as of December 31, 2017. The Company projects that its total net expected loss across its troubled U.S. public finance exposures as of December 31, 2018 will be $832 million, compared with $1,157 million as of December 31, 2017. The total net expected loss for troubled U.S. public finance exposures is net of a credit for estimated future recoveries of claims already paid. At December 31, 2018 that credit was $586 million compared with $385 million at December 31, 2017. Economic loss development on U.S. exposures in 2018 was $70 million, which was primarily attributable to Puerto Rico exposures, partially offset by the release of reserves on the Company's exposure to the City of Hartford following the State of Connecticut's (CT) agreement to pay the debt service costs of certain bonds of the City of Hartford, including those insured by the Company.
The economic benefit of approximately $14 million on non-U.S. exposures during 2018 was mainly attributable to the U.K. arterial road and changes in certain probability of default assumptions. See Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure, for details about significant developments that have taken place in Puerto Rico.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS of $69 million was mainly related to improvement in the performance of second lien U.S. RMBS transactions. The net expected loss to be paid for U.S RMBS increased from 2017 to 2018 mainly due to the SGI Transaction and collection of a large R&W settlement in 2018.

Other Structured Finance Economic Loss Development: The economic loss development attributable to structured finance, excluding U.S. RMBS, was $8 million, related to progress on efforts to workout triple-X life insurance transactions and LAE.

2017 Net Economic Loss Development

Public Finance Economic Loss Development: Public finance expected loss to be paid primarily related to U.S. exposures which had BIG net par outstanding of $7.1 billion as of December 31, 2017 compared with $7.4 billion as of December 31, 2016. The Company projected that its total net expected loss across its troubled U.S. public finance exposures as of December 31, 2017 would be $1,157 million, compared with $871 million as of December 31, 2016. Economic loss development on U.S. exposures in 2017 was $554 million, which was primarily attributable to Puerto Rico exposures.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS was $181 million and was mainly related to an R&W litigation settlement, and improved second lien U.S. RMBS recoveries.

Other Structured Finance Economic Loss Development: The net benefit attributable to structured finance (excluding U.S. RMBS) was $55 million, primarily due to a benefit from a litigation settlement related to two triple-X transactions.

2016 Net Economic Loss Development

Public Finance Economic Loss Development: Expected loss to be paid for public finance primarily related the Company's to U.S. exposures. The net par outstanding for U.S. public finance obligations rated BIG by the Company was $7.4 billion as of December 31, 2016 compared with $7.8 billion as of December 31, 2015. The Company projected that its total net expected loss across its troubled U.S. public finance exposures as of December 31, 2016 would be $871 million, compared with $771 million as of December 31, 2015. Economic loss development on U.S. exposures in 2016 was $276 million, which was primarily attributable to Puerto Rico exposures.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS was $91 million and was
mainly due to the acceleration of claim payments as a means of mitigating future losses on certain Alt-A transactions.

Other Structured Finance Economic Loss Development: The net benefit attributable to structured finance, excluding
U.S. RMBS, was $39 million, primarily due to a benefit from the purchase of a portion of an insured obligation as part of a loss
mitigation strategy and the commutation of certain assumed student loan exposures.


Loss and LAE (Financial Guaranty Insurance Contracts)
The primary differences between net economic loss development and the amount reported as loss and LAE in the consolidated statements of operations are that loss and LAE: (1) considers deferred premium revenue in the calculation of loss reserves and loss and LAE for financial guaranty insurance contracts, (2) eliminates loss and LAE related to consolidated FG VIEs and (3) does not include estimated losses on credit derivatives.

Loss and LAE reported in non-GAAP operating income (i.e., operating loss and LAE) includes losses on financial guaranty insurance contracts (other than those eliminated due to consolidation of FG VIEs), and credit derivatives.
For financial guaranty insurance contracts each transaction's expected loss to be expensed is compared with the deferred premium revenue of that transaction. When the expected loss to be expensed exceeds the deferred premium revenue, a loss is recognized in the consolidated statements of operations for the amount of such excess. Therefore, the timing of loss recognition in income does not necessarily coincide with the timing of the actual credit impairment or improvement reported in net economic loss development. Transactions (particularly BIG transactions) acquired in a business combination or seasoned portfolios assumed from legacy financial guaranty insurers generally have the largest deferred premium revenue balances. Therefore the largest differences between net economic loss development and loss and LAE on financial guaranty insurance contracts generally relate to those policies.

The amount of loss and LAE recognized in the consolidated statements of operations for financial guaranty contracts accounted for as insurance is a function of the amount of economic loss development discussed above and the deferred premium revenue amortization in a given period, on a contract-by-contract basis.

While expected loss to be paid is an important liquidity measure that provides the present value of amounts that the Company expects to pay or recover in future periods on all contracts, expected loss to be expensed is important because it presents the Company’s projection of loss and LAE that will be recognized in future periods as deferred premium revenue amortizes into income for financial guaranty insurance policies.

The following table presents the loss and LAE recorded in the consolidated statements of operations. Amounts presented are net of reinsurance.

Net Change in Fair Value of Credit Derivatives
Changes in the fair value of credit derivatives occur because of changes in the issuing company's own credit rating and credit spreads, collateral credit spreads, notional amounts, credit ratings of the referenced entities, expected terms, realized gains (losses) and other settlements, interest rates, and other market factors. With volatility continuing in the market, unrealized gains (losses) on credit derivatives may fluctuate significantly in future periods.

Except for net estimated credit impairments (i.e., net expected payments), the unrealized gains and losses on credit derivatives are expected to reduce to zero as the exposure approaches its maturity date. Changes in the fair value of the Company’s credit derivatives that do not reflect actual or expected claims or credit losses have no impact on the Company’s statutory claims-paying resources, rating agency capital or regulatory capital positions. Changes in expected losses in respect of contracts accounted for as credit derivatives are included in the discussion of “Economic Loss Development” below.
The impact of changes in credit spreads will vary based upon the volume, tenor, interest rates, and other market conditions at the time these fair values are determined. In addition, since each transaction has unique collateral and structural terms, the underlying change in fair value of each transaction may vary considerably. The fair value of credit derivative contracts also reflects the change in the Company’s own credit cost based on the price to purchase credit protection on AGC and AGM. The Company determines its own credit risk based on quoted CDS prices traded on the Company at each balance sheet date. Generally, a widening of credit spreads of the underlying obligations results in unrealized losses and the tightening of credit spreads of the underlying obligations results in unrealized gains. A widening of the CDS prices traded on AGC and AGM has an effect of offsetting unrealized losses that result from widening general market credit spreads, while a narrowing of the CDS prices traded on AGC and AGM has an effect of offsetting unrealized gains that result from narrowing general market credit spreads.
The valuation of the Company’s credit derivative contracts requires the use of models that contain significant, unobservable inputs, and are classified as Level 3 in the fair value hierarchy. The models used to determine fair value are primarily developed internally based on market conventions for similar transactions that the Company observed in the past.

Net credit derivative premiums included in the realized gains on credit derivatives line in the table above have declined in 2018, 2017 and 2016 2015 and 2014primarily due primarily to the decline in the net par outstanding to $17.0 billion at December 31, 2016 from $25.6 billion at December 31, 2015 and $35.0 billion at December 31, 2014.

During 2016,2018, unrealized fair value gains were primarily generated primarily as a result ofby CDS terminations, in the U.S. RMBS and other sectors, run-off of CDS par and price improvements on the underlying collateral of the Company’s CDS. The majorityIn addition, unrealized fair value gains were generated by the increase in credit given to the primary insurer on one of the Company's second-to-pay CDS transactions were terminated as a result of settlement agreements with several CDS counterparties.policies during the period. The unrealized fair value gains were partially offset by unrealized fair value losses resulting from wider implied net spreads across all sectors. The wider implied net spreads were primarily a result ofdriven by the decreased cost to buy protection in AGC’s and AGM’s name, as the market cost of AGC’s and AGM’s credit protection decreased significantly during the period. TheseFor those CDS transactions that were pricing at or above their floor levels, (or the minimum rate at which the Company would consider assuming these risks based on historical experience); therefore when the cost of purchasing CDS protection on AGC and AGM, which management refers to as the CDS spread on AGC and AGM, decreased the implied spreads that the Company would expect to receive on these transactions increased.


During 2015,2017 and 2016, unrealized fair value gains were primarily generated primarilyby CDS terminations, run-off of net par outstanding, and price improvements on the underlying collateral of the Company’s CDS. The majority of the CDS transactions that were terminated were as a result of settlement agreements with several CDS terminations. The Company reached a settlement agreement with one CDS counterparty to terminate five Alt-A first lien CDS transactions resulting in unrealized fair value gains of $213 million and wascounterparties. In 2016, the primary driver of the unrealized fair value gains in the U.S. RMBS sector. The Company also terminated a CMBS transaction, a Triple-X life insurance securitization transaction, and a distressed middle market CLO securitization during the period and recognized unrealized fair value gains of $41 million, $99 million and $99 million, respectively. These were the primary drivers of the unrealized fair value gains in the CMBS, Other, and pooled corporate collateralized loan obligation (CLO) sectors, respectively, during the period. The remainder of the fair value gains for the period were a result of tighter implied net spreads across all sectors. The tighter implied net spreads were primarily a result of the increased cost to buy protection in AGC’s and AGM’s name, particularly for the one year CDS spread. These transactions were pricing at or above their floor levels, therefore when the cost of purchasing CDS protection on AGC and AGM increased, the implied spreads that the Company would expect to receive on these transactions decreased. Finally, during 2015, there was a refinement in methodology to address an instance in a U.S. RMBS transaction where the Company now expects recoveries. This refinement resulted in approximately $49 million in fair value gains in 2015.

During 2014, unrealized fair value gains were generated primarily in the U.S. RMBS prime first lien, Option ARM and subprime sectors. This is primarily due to a significant unrealized fair value gain in the Option ARM and Alt-A first lien sector of approximately $543 million, as a result of the terminations of three large Alt-A first lien resecuritization transactions and one Option ARM first lien transaction during the period. In addition, there was an unrealized gain of approximately $346 million related to the change in index used to determine fair value during the fourth quarter of 2014. In the fourth quarter of 2014, new market indices were published on Option ARM and Alt-A first lien securitizations. As part of the Company’s normal review process the Company reviewed these indices and based upon the collateral make-up, collateral vintage, and collateral loss experience, determined it to be a better market indication for the Company’s Option ARM and Alt-A first lien securitizations. The unrealized fair value gains were partially offset by unrealized fair value losses generated byresulting from wider implied net spreads. The wider implied net spreads were primarily a result of the decreased cost to buy protection in AGC’s and AGM’s name, as the market cost of AGC'sAGC’s and AGM’s credit protection decreased significantly during the period. These transactions were pricing at or above their floor levels; therefore whenDuring 2017, the cost of purchasingto buy protection in AGC’s and AGM’s name, specifically the five-year CDS protectionspread, did not change materially during the period, and therefore did not have a material impact on AGCthe Company’s unrealized fair value gains and AGM decreased, the implied spreads that the Company would expect to receivelosses on these transactions increased.

Management believes that the trading level of AGC’s and AGM’s credit spreads over the past several years has been due to the correlation between AGC’s and AGM’s risk profile and the current risk profile of the broader financial markets, as well as the overall lack of liquidity in the CDS market. Offsetting the benefit attributable to AGC’s and AGM’s credit spread were higher credit spreads in the fixed income security markets relative to pre-financial crisis levels. The higher credit spreads in the fixed income security market are due to the lack of liquidity in the high-yield CDO, TruPS CDOs, and CLO markets as well as continuing market concerns over the 2005-2007 vintages of RMBS.markets.

Interest Expense

Changes in interest expense between 2015 and 2014 relate to the timing of debt issuance. In June 2014, the Company issued $500 million aggregate principal amount of 5% Senior Notes due 2024. All other long term debt of the U.S. holding companies was outstanding throughout all three years presented. See Part II, Item 8, Financial Statements and Supplementary Data, Note 16, Long-Term Debt and Credit Facilities. The following table presents the components of interest expense.

In December 2016, $150 million of debt became floating rate interest debt, that resets quarterly, at a rate equal to three month LIBOR plus a margin equal to 2.38%.

Other Operating Expenses and Amortization of Deferred Acquisition Costs
2016 compared with 2015: Other operating expenses increased in 2016 compared to 2015 due primarily to higher compensation expense and accelerated amortization of leasehold improvements as a result of the Company's move of its New York offices.

2015 compared with 2014: Other operating expenses increased in 2015 compared to 2014 due primarily to $12 million in expenses related to the Radian Asset Acquisition and expenses related to the relocation of the New York offices in the summer of 2016. The Radian Asset Acquisition expenses were comprised mainly of fees paid to financial and legal advisors and to the independent auditor. Relocation expenses include broker fees and accelerated depreciation of unamortized improvements in the current New York office.

Financial Guaranty Variable Interest Entities
 
As of December 31, 20162018 and 2015,2017, the Company consolidated 31 and 32 and 34FG VIEs, respectively. The table below presents the effects on reported GAAP income resulting from consolidating these FG VIEs and eliminating their related insurance and investment amounts.intercompany transactions. The consolidation of FG VIEs has anthe following effect on net income and shareholders' equity due to:equity.

changesChanges in fair value gains (losses) on FG VIEVIEs’ assets and liabilities are recorded in the Statement of Operations (effective January 1, 2018 the change in fair value of FG VIEs’ liabilities with recourse attributable to ISCR is recorded in OCI, instead of net income - See Item 8, Financial Statements and Supplementary Data, Note 1, Business and Basis of Presentation, for additional information). Upon adoption, the Company reclassified a loss of approximately $33 million, net of tax, from retained earnings to AOCI.

(2)The Company recorded a gain on change in fair value of equity securities in 2018 related to the Company's minority interest in the parent company of TMC Bonds LLC, which it sold in third quarter of 2018.

(3)The loss on extinguishment of debt is related to AGUS' purchase of a portion of the principal amount of AGMH's outstanding Junior Subordinated Debentures. The loss represents the difference between the amount paid to purchase AGMH's debt and the carrying value of the debt, which includes the unamortized fair value adjustments that were recorded upon the acquisition of AGMH in 2009. AGUS purchased $100 million of principal amount in 2018 and $28 million in 2017. See Item 8, Financial Statements and Supplementary Data, Note 16, Long-Term Debt and Credit Facilities, for additional information.


Economic Loss Development

     The insured portfolio includes policies accounted for under three separate accounting models depending on the characteristics of the contract and the Company’s control rights. For a discussion of assumptions and methodologies used in calculating the expected loss to be paid for all contracts, the loss estimation process and approach to projecting losses, and the measurement and recognition accounting policies under GAAP for each type of contract, see the Notes listed below in Item 8, Financial Statements and Supplementary Data.

Note 5 for expected loss to be paid
Note 6 for contracts accounted for as insurance
Note 7 for fair value methodologies for credit derivatives and FG VIEs. VIEs’ assets and liabilities
Note 8 for contracts accounted for as credit derivatives
Note 9 for FG VIEs
In order to efficiently evaluate and manage the economics of the entire insured portfolio, management complies and analyzes expected loss information for all policies on a consistent basis. The discussion of losses that follows encompasses losses on all contracts in the insured portfolio regardless of accounting model, unless otherwise specified. Net expected loss to be paid primarily consists of the present value of future: expected claim and LAE payments, expected recoveries from issuers or excess spread and other collateral in the transaction structures, cessions to reinsurers, and expected recoveries/payables for breaches of R&W and the effects of other loss mitigation strategies. Current risk free rates are used to discount expected losses at the end of each reporting period and therefore changes in such rates from period to period affect the expected loss estimates reported. Assumptions used in the determination of the net expected loss to be paid such as delinquency, severity, and discount rates and expected time frames to recovery were consistent by sector regardless of the accounting model used. The primary drivers of economic loss development are discussed below. Changes in risk free rates used to discount losses affect economic loss development, and loss and LAE; however, the effect of changes in discount rates are not indicative of actual credit impairment or improvement in the period.

2018 Net Economic Loss Development

Public Finance Economic Loss Development: Public finance expected loss to be paid primarily related to U.S. exposure, which had BIG net par outstanding of $6.4 billion as of December 31, 2018 compared with $7.1 billion as of December 31, 2017. The Company projects that its total net expected loss across its troubled U.S. public finance exposures as of December 31, 2018 will be $832 million, compared with $1,157 million as of December 31, 2017. The total net expected loss for troubled U.S. public finance exposures is net of a credit for estimated future recoveries of claims already paid. At December 31, 2018 that credit was $586 million compared with $385 million at December 31, 2017. Economic loss development on U.S. exposures in 2018 was $70 million, which was primarily attributable to Puerto Rico exposures, partially offset by the release of reserves on the Company's exposure to the City of Hartford following the State of Connecticut's (CT) agreement to pay the debt service costs of certain bonds of the City of Hartford, including those insured by the Company.
The economic benefit of approximately $14 million on non-U.S. exposures during 2018 was mainly attributable to the U.K. arterial road and changes in certain probability of default assumptions. See Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure, for details about significant developments that have taken place in Puerto Rico.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS of $69 million was mainly related to improvement in the performance of second lien U.S. RMBS transactions. The net expected loss to be paid for U.S RMBS increased from 2017 to 2018 mainly due to the SGI Transaction and collection of a large R&W settlement in 2018.

Other Structured Finance Economic Loss Development: The economic loss development attributable to structured finance, excluding U.S. RMBS, was $8 million, related to progress on efforts to workout triple-X life insurance transactions and LAE.

2017 Net Economic Loss Development

Public Finance Economic Loss Development: Public finance expected loss to be paid primarily related to U.S. exposures which had BIG net par outstanding of $7.1 billion as of December 31, 2017 compared with $7.4 billion as of December 31, 2016. The Company projected that its total net expected loss across its troubled U.S. public finance exposures as of December 31, 2017 would be $1,157 million, compared with $871 million as of December 31, 2016. Economic loss development on U.S. exposures in 2017 was $554 million, which was primarily attributable to Puerto Rico exposures.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS was $181 million and was mainly related to an R&W litigation settlement, and improved second lien U.S. RMBS recoveries.

Other Structured Finance Economic Loss Development: The net benefit attributable to structured finance (excluding U.S. RMBS) was $55 million, primarily due to a benefit from a litigation settlement related to two triple-X transactions.

2016 Net Economic Loss Development

Public Finance Economic Loss Development: Expected loss to be paid for public finance primarily related the Company's to U.S. exposures. The net par outstanding for U.S. public finance obligations rated BIG by the Company was $7.4 billion as of December 31, 2016 compared with $7.8 billion as of December 31, 2015. The Company projected that its total net expected loss across its troubled U.S. public finance exposures as of December 31, 2016 would be $871 million, compared with $771 million as of December 31, 2015. Economic loss development on U.S. exposures in 2016 was $276 million, which was primarily attributable to Puerto Rico exposures.

U.S. RMBS Economic Loss Development: The net benefit attributable to U.S. RMBS was $91 million and was
mainly due to the acceleration of claim payments as a means of mitigating future losses on certain Alt-A transactions.

Other Structured Finance Economic Loss Development: The net benefit attributable to structured finance, excluding
U.S. RMBS, was $39 million, primarily due to a benefit from the purchase of a portion of an insured obligation as part of a loss
mitigation strategy and the commutation of certain assumed student loan exposures.


Loss and LAE (Financial Guaranty Insurance Contracts)
The primary differences between net economic loss development and the amount reported as loss and LAE in the consolidated statements of operations are that loss and LAE: (1) considers deferred premium revenue in the calculation of loss reserves and loss and LAE for financial guaranty insurance contracts, (2) eliminates loss and LAE related to consolidated FG VIEs and (3) does not include estimated losses on credit derivatives.

Loss and LAE reported in non-GAAP operating income (i.e., operating loss and LAE) includes losses on financial guaranty insurance contracts (other than those eliminated due to consolidation of FG VIEs), and credit derivatives.
For financial guaranty insurance contracts each transaction's expected loss to be expensed is compared with the deferred premium revenue of that transaction. When the expected loss to be expensed exceeds the deferred premium revenue, a loss is recognized in the consolidated statements of operations for the amount of such excess. Therefore, the timing of loss recognition in income does not necessarily coincide with the timing of the actual credit impairment or improvement reported in net economic loss development. Transactions (particularly BIG transactions) acquired in a business combination or seasoned portfolios assumed from legacy financial guaranty insurers generally have the largest deferred premium revenue balances. Therefore the largest differences between net economic loss development and loss and LAE on financial guaranty insurance contracts generally relate to those policies.

The amount of loss and LAE recognized in the consolidated statements of operations for financial guaranty contracts accounted for as insurance is a function of the amount of economic loss development discussed above and the deferred premium revenue amortization in a given period, on a contract-by-contract basis.

While expected loss to be paid is an important liquidity measure that provides the present value of amounts that the Company expects to pay or recover in future periods on all contracts, expected loss to be expensed is important because it presents the Company’s projection of loss and LAE that will be recognized in future periods as deferred premium revenue amortizes into income for financial guaranty insurance policies.

The following table presents the loss and LAE recorded in the consolidated statements of operations. Amounts presented are net of reinsurance.

Loss and LAE in 2018 was mainly driven by higher loss reserves on certain Puerto Rico exposures, partially offset by the reduction of loss reserves on the City of Hartford, CT exposure and a benefit on structured finance exposures.

Loss and LAE in 2017 was mainly driven by higher loss reserves on certain Puerto Rico exposures, partially offset by a benefit from R&W settlements of $105 million and a triple-X litigation settlement.

Loss and LAE in 2016 was mainly driven by higher loss reserves on certain Puerto Rico exposures.

2018 compared with 2017: Other operating expenses increased in 2018 compared with 2017 as higher compensation expenses were partially offset by higher deferred costs as a result of increased new business production.

2017 compared with 2016: Other operating expenses in 2017 decreased slightly compared with 2016 due to lower rent in 2017 that resulted from improvements in the underlying collateral, as well as large principal paydowns made onmove of the Company's FG VIEs.New York City offices, offset by higher compensation expenses.

In 2014, the Company recorded a pre-tax net fair value gain on consolidated FG VIEs of $255 million. The primary driver of this gain, $120 million, was a result of the deconsolidation of seven VIEs. There was an additional gain of $37 million resulting from the Company exercising its option to accelerate two second lien RMBS VIEs. These two VIEs were treated as maturities during the period. The remainder of the gain for the period was driven by the price appreciation on the Company's FG VIE assets during the year resulting from improvements in the underlying collateral, as well as large principal paydowns made on the Company's FG VIEs.

Provision for Income Tax
 
Deferred income tax assets and liabilities are established for the temporary differences between the financial statement carrying amounts and tax bases of assets and liabilities using enacted rates in effect for the year in which the differences are expected to reverse. Such temporary differences relate principally to unrealized gains and losses on investments and credit derivatives, FG VIE fair value adjustments,investment basis difference, loss and LAE reserve,reserves, unearned premium reservereserves and tax attributes for net operating losses and alternative minimum tax credits and foreign tax credits.

As of December 31, 20162018 and December 31, 2015,2017, the Company had a net deferred income tax asset of $497$68 million and $276$98 million, respectively. The increasedecrease in 20162018 from 20152017 is mainly attributable to CIFG Acquisition.the utilization of alternative minimum tax credits and a decrease in tax reserves for unearned premiums.

See Part II, Item 8, Financial Statements and Supplementary Data, Note 12, Income Taxes, for more details.

The 2018 effective tax rate reflects the release of $18 million of previously recorded uncertain tax position reserves and accrued interest, due to the closing of the 2013 and 2014 audit years. In April 2017, the Company received a final letter from the IRS to close the audit for the period of 2009 - 2012, with no additional findings or changes, and as a result the Company released previously recorded uncertain tax position reserves and accrued interest of approximately $37 million in the third quarter of 2017. Other non-taxable book-to-tax differences were mostly consistent compared with the prior period, with the exception of the benefit on bargain purchase gains from the MBIA UK Acquisition in 2017 and the CIFG Acquisition in 2016.

Non-GAAP Financial Measures
 
To reflect the key financial measures that management analyzes in evaluating the Company’s operations and progress towards long-term goals, the Company discloses both financial measures determined in accordance with GAAP and financial measures not determined in accordance with GAAP (non-GAAP financial measures).

Financial measures identified as non-GAAP should not be considered substitutes for GAAP financial measures. The primary limitation of non-GAAP financial measures is the potential lack of comparability to financial measures of other companies, whose definitions of non-GAAP financial measures may differ from those of Assured Guaranty. Beginning in fourth quarter 2016, the Company’s publicly disclosed non-GAAP financial measures are different from the financial measures used by management in its decision making process and in its calculation of certain components of management compensation (core financial measures). The Company had previously excluded the effect of consolidating FG VIEs (FG VIE consolidation) in its calculation of its non-GAAP financial measures of operating income, non-GAAP operating shareholders’ equity and non-GAAP adjusted book value. Starting in fourth quarter 2016, based on the SEC's May 17, 2016 release of updated Compliance and Disclosure Interpretations of the rules and regulations on the use of non-GAAP financial measures, the Company will no longer adjust for FG VIE consolidation. However, wherever possible, the Company has separately disclosed the effect of FG VIE consolidation that is included in its non-GAAP financial measures. The prior-year non-GAAP financial measures have been updated to reflect the revised calculation.Company.
 
Management and the Board use core financial measures, which are based on non-GAAP financial measures adjusted to remove FG VIE consolidation, as well as GAAP financial measures and other factors, to evaluate the Company’s results of operations, financial condition and progress towards long-term goals. The Company removes FG VIE consolidation in its core financial measures because, although GAAP requires the Company to consolidate certain VIEs that have issued debt obligations insured by the Company, the Company does not own such VIEs and its exposure is limited to its obligation under its financial guaranty insurance contract. By disclosing non-GAAP financial measures, along with FG VIE consolidation, the Company gives investors, analysts and financial news reporters access to information that management and the Board of Directors review internally. Assured GuarantyThe Company believes its presentation of non-GAAP financial measures, andalong with the effect of FG VIE consolidation, provides information that is necessary for analysts to calculate their estimates of Assured Guaranty’s financial results in their research reports on Assured Guaranty and for investors, analysts and the financial news media to evaluate Assured Guaranty’s financial results.

GAAP requires the Company to consolidate certain VIEs that have issued debt obligations insured by the Company. However, the Company does not own such VIEs and its exposure is limited to its obligation under its financial guaranty insurance contract. Management and the Board of Directors use non-GAAP financial measures adjusted to remove FG VIE consolidation (which the Company refers to as its core financial measures), as well as GAAP financial measures and other factors, to evaluate the Company’s results of operations, financial condition and progress towards long-term goals. The Company uses these core financial measures in its decision making process and in its calculation of certain components of management compensation. Wherever possible, the Company has separately disclosed the effect of FG VIE consolidation.

Many investors, analysts and financial news reporters use non-GAAP operating shareholders’ equity, adjusted forto remove the effect of FG VIE consolidation, as the principal financial measure for valuing AGL’s current share price or projected share price and also as the basis of their decision to recommend, buy or sell AGL’s common shares. Many of the Company’s fixed income investors also use this measure to evaluate the Company’s capital adequacy.
 
Many investors, analysts and financial news reporters also use non-GAAP adjusted book value, adjusted forto remove the effect of FG VIE consolidation, to evaluate AGL’s share price and as the basis of their decision to recommend, buy or sell the AGL common shares. OperatingNon-GAAP operating income adjusted for the effect of FG VIE consolidation enables investors and analysts to evaluate the Company’s financial results as comparedin comparison with the consensus analyst estimates distributed publicly by financial databases.
 
The core financial measures that are usedthe Company uses to help determine compensation are: (1) non-GAAP operating income, adjusted forto remove the effect of FG VIE consolidation, (2) non-GAAP operating shareholders' equity, adjusted forto remove the effect of FG VIE consolidation, (3) growth in non-GAAP adjusted book value per share, adjusted forto remove the effect of FG VIE consolidation, and (4) PVP.

 The following paragraphs define each non-GAAP financial measure disclosed by the Company and describe why it is useful. ATo the extent there is a directly comparable GAAP financial measure, a reconciliation of the non-GAAP financial measure and the most directly comparable GAAP financial measure is presented below.

Non-GAAP Operating Income
 
Management believes that non-GAAP operating income is a useful measure because it clarifies the understanding of the underwriting results and financial conditionscondition of the Company and presents the results of operations of the Company excluding the fair value adjustments on credit derivatives and CCS that are not expected to result in economic gain or loss, as well as

other adjustments described below. Management adjusts non-GAAP operating income further by removing FG VIE consolidation to arrive at its core operating income measure. OperatingNon-GAAP operating income is defined as net income (loss) attributable to AGL, as reported under GAAP, adjusted for the following:
 
1)
Elimination of realized gains (losses) on the Company’s investments, except for gains and losses on securities classified as trading. The timing of realized gains and losses, which depends largely on market credit cycles, can vary considerably across periods. The timing of sales is largely subject to the Company’s discretion and influenced by market opportunities, as well as the Company’s tax and capital profile.

2)
Elimination of non-credit-impairment unrealized fair value gains (losses) on credit derivatives that are recognized in net income, which is the amount of unrealized fair value gains (losses) in excess of the present value of the expected estimated economic credit losses, and non-economic payments. Such fair value adjustments are heavily affected by, and in part fluctuate with, changes in market interest rates, the Company's credit spreads, and other market factors and are not expected to result in an economic gain or loss.
 
3)
Elimination of fair value gains (losses) on the Company’s CCS.CCS that are recognized in net income. Such amounts are affected by changes in market interest rates, the Company's credit spreads, price indications on the Company's publicly traded debt, and other market factors and are not expected to result in an economic gain or loss.
 
4)
Elimination of foreign exchange gains (losses) on remeasurement of net premium receivables and loss and LAE reserves.reserves that are recognized in net income. Long-dated receivables and loss and LAE reserves represent the present value of future contractual or expected cash flows. Therefore, the current period’s foreign exchange remeasurement gains (losses) are not necessarily indicative of the total foreign exchange gains (losses) that the Company will ultimately recognize.
 

5)
Elimination of the tax effects related to the above adjustments, which are determined by applying the statutory tax rate in each of the jurisdictions that generate these adjustments.

Non-GAAP Operating Shareholders’ Equity and Non-GAAP Adjusted Book Value
 
     Management believes that non-GAAP operating shareholders’ equity is a useful measure because it presents the equity of the Company excluding the fair value adjustments on investments, credit derivatives and CCS that are not expected to result in economic gain or loss, along with other adjustments described below. Management adjusts non-GAAP operating shareholders’ equity further by removing FG VIE consolidation to arrive at its core operating shareholders' equity and core adjusted book value.

Non-GAAP operating shareholders’ equity is the basis of the calculation of non-GAAP adjusted book value (see below). Non-GAAP operating shareholders’ equity is defined as shareholders’ equity attributable to AGL, as reported under GAAP, adjusted for the following:
 
1)
Elimination of non-credit-impairment unrealized fair value gains (losses) on credit derivatives, which is the amount of unrealized fair value gains (losses) in excess of the present value of the expected estimated economic credit losses, and non-economic payments. Such fair value adjustments are heavily affected by, and in part fluctuate with, changes in market interest rates, credit spreads and other market factors and are not expected to result in an economic gain or loss.
 
2)
Elimination of fair value gains (losses) on the Company’s CCS. Such amounts are affected by changes in market interest rates, the Company's credit spreads, price indications on the Company's publicly traded debt, and other market factors and are not expected to result in an economic gain or loss.
 
3)
Elimination of unrealized gains (losses) on the Company’s investments that are recorded as a component of accumulated other comprehensive income (AOCI) (excluding foreign exchange remeasurement). The AOCI component of the fair value adjustment on the investment portfolio is not deemed economic because the Company generally holds these investments to maturity and therefore should not recognize an economic gain or loss.


 4) Elimination of the tax asset or liabilityeffects related to the above adjustments, which are determined by applying the statutory tax rate in each of the jurisdictions that generate these adjustments.
 
Management uses non-GAAP adjusted book value, adjusted for FG VIE consolidation, to measure the intrinsic value of the Company, excluding franchise value. Growth in non-GAAP adjusted book value per share, adjusted for FG VIE consolidation (core adjusted book value), is one of the key financial measures used in determining the amount of certain long-term compensation elements to management and employees and used by rating agencies and investors. Management believes that thisnon-GAAP adjusted book value is a useful measure because it enables an evaluation of the net present value of the Company’s in-force premiums and revenues net of expected losses. Non-GAAP adjusted book value is non-GAAP operating shareholders’ equity, as defined above, further adjusted for the following:
 
1)
Elimination of deferred acquisition costs, net. These amounts represent net deferred expenses that have already been paid or accrued and will be expensed in future accounting periods.
 
2)
Addition of the net present value of estimated net future credit derivative revenue. See below.
 
3)
Addition of the deferred premium revenue on financial guaranty contracts in excess of expected loss to be expensed, net of reinsurance. This amount represents the expected future net earned premiums, net of expected losses to be expensed, which are not reflected in GAAP equity.

4) Elimination of the tax asset or liabilityeffects related to the above adjustments, which are determined by applying the statutory tax rate in each of the jurisdictions that generate these adjustments.

The unearned premiums and revenues included in non-GAAP adjusted book value will be earned in future periods, but actual earnings may differ materially from the estimated amounts used in determining current non-GAAP adjusted book value due to changes in foreign exchange rates, prepayment speeds, terminations, credit defaults and other factors.

Net Present Value of Estimated Net Future Credit Derivative Revenue

Management believes that this amount is a useful measure because it enables an evaluation of the value of future estimated revenue for contracts other than financial guaranty insurance contracts (such as non-financial guaranty insurance contracts and credit derivative revenue.derivatives). There is no corresponding GAAP financial measure. This amount represents the present value of estimated future revenue from the Company’s credit derivative in-force book of business,these contracts, net of reinsurance, ceding commissions and premium taxes, for contracts without expected economic losses, and is discounted at 6%. Estimated net future credit derivative revenue may change from period to period due to changes in foreign exchange rates, prepayment speeds, terminations, credit defaults or other factors that affect par outstanding or the ultimate maturity of an obligation.

PVP or Present Value of New Business Production     

Management believes that PVP is a useful measure because it enables the evaluation of the value of new business production for the Company by taking into account the value of estimated future installment premiums on all new contracts underwritten in a reporting period as well as premium supplements and additional installment premium on existing contracts as to which the issuer has the right to call the insured obligation but has not exercised such right, whether in insurance or credit derivative contract form, which management believes GAAP gross written premiums and the net credit derivative premiums received and receivable portion of net realized gains and other settlements on credit derivatives (Credit Derivative Realized Gains (Losses)) do not adequately measure. PVP in respect of financial guaranty contracts written in a specified period is defined as gross upfront and installment premiums received and the present value of gross estimated future installment premiums, discounted, in each case, at 6%. For purposes of the PVP calculation, management discounts estimated futureUnder GAAP, financial guaranty installment premiums on insurance contracts at 6%, while under GAAP, these amounts are discounted at a risk free rate. Additionally, under

GAAP, management records future installment premiums on financial guaranty insurance contracts covering non-homogeneous pools of assets

based on the contractual term of the transaction, whereas for PVP purposes, management records an estimate of the future installment premiums the Company expects to receive, which may be based upon a shorter period of time than the contractual term of the transaction. Actual future net earned or written premiums and Credit Derivative Realized Gains (Losses) may differ from PVP due to factors including, but not limited to, changes in foreign exchange rates, prepayment speeds, terminations, credit defaults, or other factors that affect par outstanding or the ultimate maturity of an obligation.

Exposures by Reinsurer
Ceded par outstanding represents the portion of insured risk ceded to external reinsurers. Under these relationships, the Company cedes a portion of its insured risk in exchange for a premium paid to the reinsurer. The Company remains primarily liable for all risks it directly underwrites and is required to pay all gross claims. It then seeks reimbursement from the reinsurer for its proportionate share of claims. The Company may be exposed to risk for this exposure if it were required to pay the gross claims and not be able to collect ceded claims from an assuming company experiencing financial distress. A number of the financial guaranty insurers to which the Company has ceded par have experienced financial distress and as a result have been downgraded by the rating agencies. In addition, state insurance regulators have intervened with respect to some of these insurers.

In accordance with U.S. statutory accounting requirements and U.S. insurance laws and regulations, in order for the Company to receive credit for liabilities ceded to reinsurers domiciled outside of the U.S., such reinsurers must secure their liabilities to the Company. All of the unauthorized reinsurers in the table below are required to post collateral for the benefit of the Company in an amount at least equal to the sum of their ceded unearned premium reserve, loss reserves and contingency reserves, all calculated on a statutory basis of accounting. In addition, certain authorized reinsurers in the table below post collateral on terms negotiated with the Company. Collateral may be in the form of letters of credit or trust accounts. The total collateral posted by all non-affiliated reinsurers as of December 31, 2016 was approximately $387 million.

 Assumed par outstanding represents the amount of par assumed by the Company from third party insurers and reinsurers, including other monoline financial guaranty companies. Under these relationships, the Company assumes a portion

of the ceding company’s insured risk in exchange for a premium. The Company may be exposed to risk in this portfolio in that the Company may be required to pay losses without a corresponding premium in circumstances where the ceding company is experiencing financial distress and is unable to pay premiums.
In addition to assumed and ceded reinsurance arrangements, the Company may also have exposure to financial guaranty insurers in "second-to-pay" transactions, where the Company provides insurance on an obligation that is already insured by another financial guarantor. In that case, if the underlying obligor and the financial guarantor both fail to pay an amount scheduled to be paid, the Company would be obligated to pay. The Company underwrites these transactions based on the underlying obligation, without regard to the financial guarantor. See Part II, Item 8, Financial Statements and Supplementary Data, Note 13, Reinsurance and Other Monoline Exposures.

Exposure to Puerto Rico
         
The Company hashad insured exposure to general obligation bonds of the Commonwealth of Puerto Rico (Puerto Rico or the Commonwealth) and various obligations of its related authorities and public corporations aggregating $4.8 billion net par as of December 31, 2016,2018, all of which arewas rated BIG. Puerto Rico has experienced significant general fund budget deficits in recent years and a challenging economic environment.environment since at least the financial crisis. In 2017, Hurricane Maria created additional challenges for Puerto Rico. Beginning on January 1, 2016, a number of Puerto Rico creditsexposures have defaulted on bond payments, and the Company has now paid claims on severalall of its Puerto Rico credits as shown in the table "Puertoexposures except for Puerto Rico Net Par Outstanding" below.Aqueduct and Sewer Authority (PRASA), Municipal Finance Agency (MFA) and University of Puerto Rico (U of PR). Additional information about recent developments in Puerto Rico and the individual creditsexposures insured by the Company may be found in Part II, Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure.

The Company groups its Puerto Rico exposure into three categories:

Constitutionally Guaranteed. The Company includes in this category public debt benefiting from Article VI of the Constitution of the Commonwealth, which expressly provides that interest and principal payments on the public debt are to be paid before other disbursements are made.

Public Corporations – Certain Revenues Potentially Subject to Clawback. The Company includes in this category the debt of public corporations for which applicable law permits the Commonwealth to claw back,

subject to certain conditions and for the payment of public debt, at least a portion of the revenues supporting the bonds the Company insures. As a Constitutionalconstitutional condition to clawback, available Commonwealth revenues for any fiscal year must be insufficient to pay Commonwealth debt service before the payment of any appropriations for that year.  The Company believes that this condition has not been satisfied to date, and accordingly that the Commonwealth has not to date been entitled to clawbackclaw back revenues supporting debt insured by the Company.As described in Part II, Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure, the Company sued various Puerto Rico governmental officials in the United States District Court, District of Puerto Rico asserting that Puerto Rico's recent attempt to claw back pledged taxes is unconstitutional, and demanding declaratory and injunctive relief.

Other Public Corporations. The Company includes in this category the debt of public corporations that are supported by revenues it does not believe are subject to clawback.

is expected to increase to approximately $1.0 billion prior to September 30, 2036.


The tables above include the par amount of financial guaranty contracts accounted for as derivatives of $108 million with a fair value of $2 million, net of reinsurance. The Company’s credit derivative transactions are governed by ISDA documentation, and the Company is required to make a loss payment on them only upon the occurrence of one or more defined credit events with respect to the referenced securities or loans.

The Company rates $283 million of its direct net par exposure to the Republic of Hungary BIG. The sub-sovereign transaction it rates BIG is an infrastructure financing dependent on payments by government agencies, while the non-sovereign transactions it rates BIG are covered mortgage bonds issued by Hungarian banks.  The Company rates one insured Hungarian covered bond transaction investment grade.

The Company does not rate any of its direct exposure to the Republic of Italy BIG.  The Company’s sub-sovereign exposure to Italy depends on payments by Italian governmental entities, while its non-sovereign Italian exposure is comprised primarily of securities backed by Italian residential mortgages or in one case a government-sponsored water utility.

The Company rates all of its direct exposure to the Kingdom of Spain and the Republic of Portugal BIG.  The Company’s direct sub-sovereign exposure to Spain and Portugal includes infrastructure financings dependent on payments by sub-sovereigns and government agencies and financings dependent on lease and other payments by sub-sovereigns and government agencies.

The $202 million net insured par exposure in Turkey is to DPR securitizations sponsored by a major Turkish bank. These DPR securitizations were established outside of Turkey and involve payment orders in U.S. dollars, pounds sterling and Euros from persons outside of Turkey to beneficiaries in Turkey who are customers of the sponsoring bank. The sponsoring bank's correspondent banks have agreed to remit all such payments to a trustee-controlled account outside Turkey, where debt service payments for the DPR securitization are given priority over payments to the sponsoring bank.

Indirect Exposure to Selected European CountriesReinsurance Exposures
 
The Company considers economichas exposure to reinsurers through reinsurance arrangements (both as a Selected European Country to be indirect when that exposure relates to only a small portion ofceding company and as an insured transaction that otherwise is not related to that Selected European Country, and the Company has excluded its indirect exposure to the Selected European Countries from the exposure tables above. The Company has such indirect exposure to Selected European Countries through insurance it provides on pooled corporate and commercial receivables transactions.
The Company’s pooled corporate obligations with indirect exposure to Selected European Countries are highly diversified in terms of obligors and, except in the case of TruPS CDOs or transactions backed by perpetual preferred securities, highly diversified in terms of industry. Most pooled corporate obligations are structured to limit exposure to any given obligor and any given non-U.S. country or region and generally benefit from embedded credit enhancement which allows a transaction a certain level of losses in the underlying collateral without causing the Company to pay a claim. The Company’s commercial receivable transactions with indirect exposure to Selected European Countries are rail car lease transactions and aircraft lease transactions where some of the lessees have a nexus with the Selected European Countries. Like the pooled corporate transactions, the commercial receivable transactions generally benefit from embedded credit enhancement which allows a transaction a certain level of losses in the underlying collateral without causing the Company to pay a claim.assuming company).

The Company has excluded fromAssumed outstanding exposure represents the exposure tables above its indirect economic exposure to the Selected European Countries through policies it provides on pooled corporate and commercial receivables transactions. The Company calculates indirect exposure to a country by multiplying the par amount of a transaction insuredexposure assumed by the Company times the percent of the relevant collateral pool reported as having a nexus to the country. On that basis, the Company has calculated exposure of $115 million to Selected European Countries (plus Greece) in transactions with $2.8 billion of net par outstanding. The indirect exposure to credits with a nexus to Greece is $3 million across several highly rated pooled corporate obligations with net par outstanding of $129 million.
Identifying Exposure to Selected European Countries
When the Company directly insures an obligation, it assigns the obligation to a geographic location or locations based on its view of the geographic location of the risk. For most exposures this can be a relatively straight-forward determination as, for example, a debt issue supported by availability payments for a toll road in a particular country. The Company may also assign portions of a risk to more than one geographic location as it has, for example, in a residential mortgage backed security backed by residential mortgage loans in both Germany and Italy. The Company may also have exposures to the Selected

European Countries in business assumed from third party insurers and reinsurers. In the case of assumed business,Under these relationships, the Company depends upon geographic information providedassumes a portion of the ceding company’s insured risk in exchange for a premium. The Company may be exposed to risk in this portfolio in that the Company may be required to pay losses without a corresponding premium in circumstances where the ceding company is experiencing financial distress and is unable to pay premiums.


Ceded outstanding exposure represents the portion of insured risk ceded to external reinsurers. Under these relationships, the Company has ceded a portion of its insured risk to the reinsurer in exchange for the reinsurer receiving a share of the Company's premiums for the insured risk (typically, net of a ceding commission). The Company remains primarily liable for all risks it directly underwrites and is required to pay all gross claims. It then seeks reimbursement from the reinsurer for its proportionate share of claims. The Company may be exposed to risk for this exposure if it were required to pay the gross claims and not be able to collect ceded claims from an assuming company experiencing financial distress. The Company's ceded contracts generally allow the Company to recapture ceded financial guaranty business after certain triggering events, such as reinsurer downgrades. In accordance with U.S. statutory accounting requirements and U.S. insurance laws and regulations, in order for the Company to receive credit for liabilities ceded to reinsurers domiciled outside of the U.S., such reinsurers must secure their liabilities to the Company. The total collateral posted by the primary insurer.all non-affiliated reinsurers as of December 31, 2018 was approximately $80 million. 


Liquidity and Capital Resources
 
Liquidity Requirements and Sources

AGL and its Holding Company Subsidiaries
 
The liquidity of AGL, AGUS and AGMH is largely dependent on dividends from their operating subsidiaries and their access to external financing. The liquidity requirements of these entities include the payment of operating expenses, interest on debt issued by AGUS and AGMH, and dividends on AGL's common shares. AGL and its holding company subsidiaries may also require liquidity to make periodic capital investments in their operating subsidiaries, purchase the Company's outstanding debt, or in the case of AGL, to repurchase its common shares pursuant to its share repurchase authorization. In the ordinary course of business, the Company evaluates its liquidity needs and capital resources in light of holding company expenses and dividend policy, as well as rating agency considerations. The Company also subjects its cash flow projections and its assets to a stress test, maintaining a liquid asset balance of one time its stressed operating company net cash flows. Management believes that AGL will have sufficient liquidity to satisfy its needs over the next twelve months. See “Insurance Company Regulatory Restrictions”“Distributions From Subsidiaries” below for a discussion of the dividend restrictions of its insurance company subsidiaries.


The following table presents significant holding company cash flow activity (other than investment income, expenses and taxes) related to distributions from subsidiaries and outflows for debt service and dividends, dividends to AGL shareholders and other capital management activities.

Dividends
Distributions From Subsidiaries

The Company anticipates that for the next twelve months, amounts paid by AGL’s direct and indirect insurance company subsidiaries as dividends or other distributions will be a major source of its liquidity. The insurance company subsidiaries’ ability to pay dividends depends upon their financial condition, results of operations, cash requirements, other potential uses for such funds, and compliance with rating agency requirements, and is also subject to restrictions contained in the insurance laws and related regulations of their states of domicile. Dividend restrictions applicable to AGC, AGM, MAC, and to AG Re and AGRO are described in Part II, Item 8, Financial Statements and Supplementary Data, Note 11, Insurance Company Regulatory Requirements.


Dividend restrictions by insurance company subsidiary are as follows:

The maximum amount available during 20172019 for AGM to distribute as dividends without regulatory approval is estimated to be approximately $232$172 million, of which approximately $81$74 million is estimated to be available for distribution in the first quarter of 2017.2019.

The maximum amount available during 20172019 for AGC to distribute as ordinary dividends is approximately $107$123 million, of which approximately $29$42 million is available for distribution in the first quarter of 2017.2019.

The maximum amount available during 20172019 for MAC to distribute as dividends to MAC Holdings, which is owned by AGM and AGC, without regulatory approval is estimated to be approximately $49 million.  MAC currently intends to allocate$32 million, of which approximately $5 million is available for distribution in the distributionfirst quarter of such amount quarterly in 2017. 2019.

Based on the applicable law and regulations, in 20172019 AG Re has the capacity to (i) make capital distributions in an aggregate amount up to $128 million without the prior approval of the Authority and (ii) declare and pay dividends in an aggregate amount up to the limitapproximately $312 million as of its outstanding statutory surplus, which is $314 million.December 31, 2018. Such dividend capacity is further limited by the actual amount of AG Re’s unencumbered assets, which amount changes

from time to time due in part to collateral posting requirements. As of December 31, 2016,2018, AG Re had unencumbered assets of approximately $596$416 million.

Based on the applicable law and regulations, in 2019 AGRO has the capacity to (i) make capital distributions in an aggregate amount up to $21 million without the prior approval of the Authority and (ii) declare and pay dividends in an aggregate amount up to approximately $96 million as of December 31, 2018. Such dividend capacity is further limited by the actual amount of AGRO’s unencumbered assets, which amount changes from time to time due in part to collateral posting requirements. As of December 31, 2018, AGRO had unencumbered assets of approximately $342 million.

Generally, dividends paid by a U.S. company to a Bermuda holding company are subject to a 30% withholding tax. After AGL became tax resident in the U.K., it became subject to the tax rules applicable to companies resident in the U.K., including the benefits afforded by the U.K.’s tax treaties. The income tax treaty between the U.K. and the U.S. reduces or eliminates the U.S. withholding tax on certain U.S. sourced investment income (to 5% or 0%), including dividends from U.S. subsidiaries to U.K. resident persons entitled to the benefits of the treaty.

Each of the Company's insurance company subsidiaries may, with the approval of the relevant regulator, repurchase shares of its stock from its parent, so providing its parent with additional liquidity. AGC made such repurchases in 2018, AGM made such repurchases in 2017 and 2016 and MAC made such repurchases in 2017. See Item 8, Financial Statements and Supplementary Data, Note 11, Insurance Company Regulatory Requirements, for more information.

External Financing

From time to time, AGL and its subsidiaries have sought external debt or equity financing in order to meet their obligations. External sources of financing may or may not be available to the Company, and if available, the cost of such financing may not be acceptable to the Company.

On June 20, 2014, AGUS issued $500 million of 5% Senior Notes due 2014. The notes are guaranteed by AGL. The net proceeds of the notes were used for general corporate purposes, including the purchase of AGL common shares.

Intercompany Loans and Guarantees

On March 30, 2015, AGUS loaned $200 million to AGC to facilitate the acquisition of Radian Asset on April 1, 2015. AGC repaid the loan in full on April 14, 2015.

From time to time, AGL and its subsidiaries have entered into intercompany loan facilities. For example, on October 25, 2013, AGL, as borrower, and AGUS, as lender, entered into a revolving credit facility pursuant to which AGL may, from time to time, borrow for general corporate purposes. Under the credit facility, AGUS committed to lend a principal amount not exceeding $225 million in the aggregate. SuchIn September 2018, AGL and AGUS amended the revolving credit facility to extend the commitment terminates onuntil October 25, 20182023 (the loan commitment termination date). The unpaid principal amount of each loan will bear semi-annual interest at a fixed rate equal to 100% of the then applicable Federal short-term or mid-term interest rate as the case may be, as determined under Internal Revenue Code Sec.Section 1274(d), and interest on all loans will be computed for the actual number of days elapsed on the basis of a year consisting of 360 days. Accrued interest on all loans will be paid on the last day of each June and December, beginning on December 31, 2013, and at maturity. AGL must repay the then unpaid principal amounts of the loans, if any, by the third anniversary of the loan termination date. No amounts are currently outstanding underAGL has not drawn upon the credit facility.

In addition, in 2012 AGUS borrowed $90 million from its affiliate AGRO to fund the acquisition of MAC. In 2018 the maturity date was extended to November 2023. During 2018, 2017 and 2016, AGUS repaid $10 million, $10 million and $20

million, respectively, in outstanding principal as well as accrued anyand unpaid interest, and the parties agreed to extend the maturity date of the loan from May 2017 to November 2019.interest. As of December 31, 2016, $702018, $50 million remained outstanding.

Furthermore, AGL fully and unconditionally guarantees the payment of the principal of, and interest on, the $1,130 million aggregate principal amount of senior notes issued by AGUS and AGMH, and the $450 million aggregate principal amount of junior subordinated debentures issued by AGUS and AGMH, in each case, as described under "Commitments and Contingencies -- Long-Term Debt Obligations" below.

Cash and Investments

As of December 31, 2016,2018, AGL had $36$45 million in cash and short-term investments. AGUS and AGMH had a total of $259$192 million in cash and short-term investments. In addition, the Company's U.S. holding companies have $147$26 million in fixed-maturity securities (excluding AGUS's investment in AGMH's debt) with weighted average duration of 0.21.3 years.


Insurance Company Subsidiaries
 
Liquidity of the insurance company subsidiaries is primarily used to pay for:

operating expenses,
claims on the insured portfolio,
posting of collateral in connection with credit derivatives and reinsurance transactions,
reinsurance premiums,
dividends or other distributions to AGL, AGUS and/or AGMH, as applicable,
posting of collateral in connection with reinsurance and credit derivative transactions,
reinsurance premiums,
principal of and, where applicable, interest on surplus notes, and
capital investments in their own subsidiaries, where appropriate.

On June 30, 2016, MAC obtained approval from the NYDFS to repay its $300 million surplus note to Municipal Assurance Holdings Inc. (MAC Holdings) and its $100 million surplus note (plus accrued interest) to AGM. Accordingly, on June 30, 2016, MAC transferred cash and/or marketable securities to (i) MAC Holdings in an aggregate amount equal to $300 million, and (ii)  AGM in an aggregate amount of $102.5 million. MAC Holdings, upon receipt of such $300 million from MAC, distributed cash and/or marketable securities in an aggregate amount of $300 million to its shareholders, AGM and AGC, in proportion to their respective 61% and 39% ownership interests such that AGM received $182 million and AGC received $118 million.

On November 25, 2016, the New York Superintendent approved AGM's request to repurchase 125 of its shares of common stock from its direct parent, AGMH, for approximately $300 million. AGM implemented the stock redemption plan in December 2016. Each share repurchased by AGM was retired and ceased to be an authorized share. Pursuant to AGM's Amended and Restated Charter, the par value of AGM's remaining shares of common stock issued and outstanding increased automatically in order to maintain AGM's total paid-in capital at $15 million and its authorized capital at $20 million.

Management believes that itsthe insurance subsidiaries’ liquidity needs for the next twelve months can be met from current cash, short-term investments and operating cash flow, including premium collections and coupon payments as well as scheduled maturities and paydowns from their respective investment portfolios. The Company targets a balance of its most liquid assets including cash and short-term securities, Treasuries, agency RMBS and pre-refunded municipal bonds equal to 1.5 times its projected operating company cash flow needs over the next four quarters. The Company intends to hold and has the ability to hold temporarily impaired debt securities until the date of anticipated recovery.recovery of amortized cost.
 
Beyond the next twelve months, the ability of the operating subsidiaries to declare and pay dividends may be influenced by a variety of factors, including market conditions, insurance regulations and rating agency capital requirements and general economic conditions.
 
Insurance policies issued provide, in general, that payments of principal, interest and other amounts insured may not be accelerated by the holder of the obligation. Amounts paid by the Company therefore are typically in accordance with the obligation’s original payment schedule, unless the Company accelerates such payment schedule, at its sole option.
 

 Payments made in settlement of the Company’s obligations arising from its insured portfolio may, and often do, vary significantly from year-to-year, depending primarily on the frequency and severity of payment defaults and whether the Company chooses to accelerate its payment obligations in order to mitigate future losses.

As of December 31, 2016, the Company had exposure of approximately $528 million to a long-term infrastructure project that was financed by bonds that mature prior to the expiration of the project concession. The Company expects the cash flows from the project to be sufficient to repay all of the debt over the life of the project concession, and also expects the debt to be refinanced in the market at or prior to its maturity. If the issuer is unable to refinance the debt due to market conditions, the Company may have to pay claims when the debt matures from 2018 to 2022, and then recover from cash flows produced by the project in the future. The Company generally projects that in most scenarios it will be fully reimbursed for such claim payments. However, the recovery of such amounts is uncertain and may take from 10 to 35 years, depending on the performance of the underlying collateral.

In addition, the Company has net par exposure to the general obligation bonds of Puerto Rico and various obligations of its related authorities and public corporations aggregating $4.8 billion, , all of which areis rated BIG. Puerto Rico has experienced significant general fund budget deficits in recent years. Beginning in 2016, the Commonwealth hasand certain related authorities and public corporations have defaulted on obligations to make payments on its debt. In addition to high debt levels, Puerto Rico faces a challenging economic environment.environment exacerbated by the impact of hurricane Maria in September 2017. Information regarding the Company's exposure to the Commonwealth of Puerto Rico and its related authorities and public corporations is set forth in Part II, Item 8, Financial Statements and Supplementary Data, Note 4, Outstanding Exposure.

In connection with the acquisition of AGMH, AGM agreed to retain the risks relating to the debt and strip policy portions of the leveraged lease business. In a leveraged lease transaction, a tax-exempt entity (such as a transit agency) transfers tax benefits to a tax-paying entity by transferring ownership of a depreciable asset, such as subway cars. The tax-exempt entity then leases the asset back from its new owner.

If the lease is terminated early, the tax-exempt entity must make an early termination payment to the lessor. A portion of this early termination payment is funded from monies that were pre-funded and invested at the closing of the leveraged lease transaction (along with earnings on those invested funds). The tax-exempt entity is obligated to pay the remaining, unfunded portion of this early termination payment (known as the strip coverage) from its own sources. AGM issued financial guaranty insurance policies (known as strip policies) that guaranteed the payment of these unfunded strip coverage amounts to the lessor, in the event that a tax-exempt entity defaulted on its obligation to pay this portion of its early termination payment. Following such events, AGM can then seek reimbursement of its strip policy payments from the tax-exempt entity, and can also sell the transferred depreciable asset and reimburse itself from the sale proceeds.

Currently, all the leveraged lease transactions in which AGM acts as strip coverage provider are breaching a rating trigger related to AGM and are subject to early termination. However, early termination of a lease does not result in a draw on the AGM policy if the tax-exempt entity makes the required termination payment. If all the leases were to terminate early and the tax-exempt entities did not make the required early termination payments, then AGM would be exposed to possible liquidity claims on gross exposure of approximately $755 million as of December 31, 2018. To date, none of the leveraged lease transactions that involve AGM has experienced an early termination due to a lease default and a claim on the AGM policy. At December 31, 2018, approximately $1.7 billion of cumulative strip par exposure had been terminated since 2008 on a consensual basis. The consensual terminations have resulted in no claims on AGM.

The terms of the Company’s CDS contracts generally are modified from standard CDS contract forms approved by ISDA in order to provide for payments on a scheduled "pay-as-you-go" basis and to replicate the terms of a traditional financial guaranty insurance policy. Some contractsHowever, the Company entered into asmay also be required to pay if the credit protection seller, however, utilize standard ISDA settlement mechanics of cash settlement (i.e., a process to value the loss of market value of a reference obligation)obligor becomes bankrupt or physical settlement (i.e., delivery ofif the reference obligation against payment of principal by the protection seller)were restructured if, after negotiation, those credit events are specified in the documentation for the credit derivative transactions. Furthermore, the Company may be required to make a payment due to an event that is unrelated to the performance of a “credit event,” as definedthe obligation referenced in the relevant contract. Cash settlementcredit derivative. If events of default or physical settlement generally requirestermination events specified in the credit derivative documentation were to occur, the Company may be required to make a cash termination payment of a larger amount,to its swap counterparty upon such termination. Any such payment would probably occur prior to the maturity of the reference obligation and be in an amount larger than would settlementthe amount due for that period on a “pay-as-you-go” basis.

The transaction documentation with one counterparty for $250 million of the CDS insured by AGC requires AGC to post collateral, subject to a cap, to secure its obligation to make payments under such contracts. As of December 31, 2016, the Company was posting approximately $116 million to secure its obligations under CDS. Of that amount, approximately $100 million related to $516 million in CDS gross par insured where the amount of required collateral is capped and the remaining $16 million related to $174 million in CDS gross par insured where the amount of required collateral is based on movements in the mark-to-market valuation of the underlying exposure. In February 2017, the Company terminated its remaining CDS contracts with one of its counterparties as to which it has a cap on its posting requirement and relating to approximately $183 million gross par and $732018, AGC had posted $1 million of collateral posted, as December 31, 2016,to satisfy these requirements and the collateral is being returned to the Company.
maximum posting requirement was $250 million.

Junior Subordinated Debentures issued by AGMH.Debentures.  On November 22, 2006, AGMH issued $300 million face amount of Junior Subordinated Debentures with a scheduled maturity date of December 15, 2036 and a final repayment date of December 15, 2066. The final repayment date of December 15, 2066 may be automatically extended up to four times in five-year increments provided certain conditions are met. The debentures are redeemable, in whole or in part, at any time prior to December 15, 2036 at their principal amount plus accrued and unpaid interest to the date of redemption or, if greater, the make-whole redemption price. Interest on the debentures will accrue from November 22, 2006 to December 15, 2036 at the annual rate of 6.4%. If any amount of the debentures remains outstanding after December 15, 2036, then the principal amount of the outstanding debentures will bear interest at a floating interest rate equal to one-month LIBOR plus 2.215% until repaid. LIBOR may be discontinued. See the Risk Factor captioned "The Company may be adversely impacted by the transition from LIBOR as a reference rate" under Risks Related to the Financial, Credit and Financial Guaranty Markets in Part I, Item 1A, Risk Factors. AGMH may elect at one or more times to defer payment of interest on the debentures for one or more consecutive interest periods that do not exceed ten years. In connection with the completion of this offering, AGMH entered into a replacement capital covenant for the benefit of persons that buy, hold or sell a specified series of AGMH long-term indebtedness ranking senior to the debentures. Under the covenant, the debentures will not be repaid, redeemed, repurchased or defeased by AGMH or any of its subsidiaries on or before the date that is twenty years prior to the final repayment date, except to the extent that AGMH has received proceeds from the sale of replacement capital securities. The proceeds from this offering were used to pay a dividend to the shareholders of AGMH. In 2018 and 2017, AGUS purchased $100 million and $28 million of par, respectively, of the debentures, which resulted in a loss on extinguishment of debt on a consolidated basis of $34 million in 2018 and $9 million in 2017. The Company may choose to make additional purchases of this or other Company debt in the future.

Recourse Credit Facility
In connection with the acquisition of AGMH, AGM agreed to retain the risks relating to the debt and strip policy portions of the leveraged lease business. The liquidity risk to AGM related to the strip policy portion of the leveraged lease business was previously mitigated by the strip coverage facility described below.
In a leveraged lease transaction, a tax-exempt entity (such as a transit agency) transfers tax benefits to a tax-paying entity by transferring ownership of a depreciable asset, such as subway cars. The tax-exempt entity then leases the asset back from its new owner.
If the lease is terminated early, the tax-exempt entity must make an early termination payment to the lessor. A portion of this early termination payment is funded from monies that were pre-funded and invested at the closing of the leveraged lease transaction (along with earnings on those invested funds). The tax-exempt entity is obligated to pay the remaining, unfunded portion of this early termination payment (known as the strip coverage) from its own sources. AGM issued financial guaranty insurance policies (known as strip policies) that guaranteed the payment of these unfunded strip coverage amounts to the lessor, in the event that a tax-exempt entity defaulted on its obligation to pay this portion of its early termination payment. Following such events, AGM can then seek reimbursement of its strip policy payments from the tax-exempt entity, and can also sell the transferred depreciable asset and reimburse itself from the sale proceeds.

Currently, all the leveraged lease transactions in which AGM acts as strip coverage provider are breaching a rating trigger related to AGM and are subject to early termination. However, early termination of a lease does not result in a draw on the AGM policy if the tax-exempt entity makes the required termination payment. If all the leases were to terminate early and the tax-exempt entities do not make the required early termination payments, then AGM would be exposed to possible liquidity claims on gross exposure of approximately $953 million as of December 31, 2016. To date, none of the leveraged lease

transactions that involve AGM has experienced an early termination due to a lease default and a claim on the AGM policy. At December 31, 2016, approximately $1.5 billion of cumulative strip par exposure had been terminated since 2008 on a consensual basis. The consensual terminations have resulted in no claims on AGM.
On July 1, 2009, AGM and Dexia Crédit Local S.A., acting through its New York Branch (Dexia Crédit Local (NY)), entered into a credit facility (the Strip Coverage Facility). Under the Strip Coverage Facility, Dexia Crédit Local (NY) agreed to make loans to AGM to finance all draws made by lessors on AGM strip policies that were outstanding as of November 13, 2008, up to the commitment amount. There have never been any borrowings under the Strip Coverage Facility, the amount of the leveraged leases covered by the Strip Coverage Facility has declined since July 1, 2009 and, to date, none of the leveraged lease transactions in which AGM acts as the strip coverage provider has experienced an early termination due to a lease default. Consequently, and in view of the credit quality of the relevant tax-exempt entities and the cost of the Strip Coverage Facility, the Company determined that maintaining the Strip Coverage Facility was no longer warranted. On July 29, 2016, the parties terminated the Strip Coverage Facility.

Committed Capital Securities
    
Each of AGC and AGM have issuedentered into put agreements with four separate custodial trusts allowing AGC and AGM, respectively, to issue an aggregate of $200 million of CCS pursuant to transactions in which AGC CCS or AGM’s Committed Preferred Trust Securities (the AGM CPS), as applicable, were issued by custodial trusts created for the primary purpose of issuing such securities, investing the proceeds in high-quality assets and providing put options to AGC or AGM, as applicable. The put options allow AGC and AGM to issue non-cumulative redeemable perpetual preferred securities to the trusts in exchange for cash. For both AGC and AGM, four initial trusts wereEach custodial trust was created each with an initial aggregatefor the primary purpose of issuing $50 million face amount of $50 million.CCS, investing the proceeds in high-quality assets and entering into put options with AGC or AGM, as applicable. The Company does not consider itself to be the primary beneficiary of the trusts for either the AGC or AGM CCS and the trusts are not consolidated in Assured Guaranty's financial statements.

The trusts provide AGC and AGM access to new equity capital at their respective sole discretion through the exercise of the put options. Upon AGC's or AGM's exercise of its put option, the relevant trust will liquidate its portfolio of eligible assets and use the proceeds to purchase the AGC or AGM preferred stock, as applicable. AGC or AGM may use the proceeds from suchits sale of its preferred stock to the trusts for any purpose, including the payment of claims. The put agreements have no scheduled termination date or maturity. However, each put agreement will terminate if (subject to certain grace periods) specified events occur.

Both AGC Committed Capital Securities.AGC entered into separate put agreements with four custodial trusts with respect to its CCS in April 2005. The AGC put options have not been exercised through the date of this filing. Initially, all of AGC CCS were issued to a special purpose pass-through trust (the Pass-Through Trust). The Pass-Through Trust was dissolved in April 2008 and the AGC CCS were distributed to the holders of the Pass-Through Trust's securities. Neither the Pass-Through Trust nor the custodial trusts are consolidated in the Company's financial statements.  Income distributions on the Pass-Through Trust securities and CCS were equal to an annualized rate of one-month LIBOR plus 110 basis points for all periods ending on or prior to April 8, 2008. Following dissolution of the Pass-Through Trust, distributions on the AGC CCS are determined pursuant to an auction process. On April 7, 2008 this auction process failed, thereby increasing the annualized rate on the AGC CCS to one-month LIBOR plus 250 basis points. Distributions on the AGC preferred stock will be determined pursuant to the same process. AGC continuesAGM continue to have the ability to exercise itstheir respective put optionoptions and cause the related trusts to purchase their preferred stock.

Prior to 2008 or 2007, the amounts paid on the CCS were established through an auction process. All of those auctions failed in 2008 or 2007, and the rates paid on the CCS increased to their respective maximums. The annualized rate on the AGC Preferred Stock.
CCS is one-month LIBOR plus 250 bps, and the annualized rate on the AGM Committed Capital Securities.AGM entered into separate put agreements with four custodial trusts with respect to its CCS in June 2003. The AGM put options have not been exercised through the date of this filing. AGM pays a floating put premium to the trusts, which represents the difference between the commercial paper yield and the winning auction rate (plus all fees and expenses of the trust). If an auction does not attract sufficient clearing bids, however, the auction ratePreferred Trust Securities (CPS) is subject to a maximum rate of one-month LIBOR plus 200 basis points forbps. LIBOR may be discontinued. See the next succeeding distribution period. BeginningRisk Factor captioned "The Company may be adversely impacted by the transition from LIBOR as a reference rate" under Risks Related to the Financial, Credit and Financial Guaranty Markets in August 2007, the AGM CCS required the maximum rate for each of the relevant trusts. AGM continues to have the ability to exercise its put option and cause the related trusts to purchase AGM Preferred Stock.Part I, Item 1A, Risk Factors.

(1)The number of securities does not add across because lots consisting of the same securities have been purchased at different times and appear in both categories above (i.e., less than 12 months and 12 months or more). If a security appears in both categories, it is counted only once in the total column.


Of the securities in an unrealized loss position for 12 months or more as of December 31, 2016, 412018, 38 securities had unrealized losses greater than 10% of book value. The total unrealized loss for these securities as of December 31, 20162018 was $59$43 million. As of December 31, 2015,2017, of the securities in an unrealized loss position for 12 months or more, nine28 securities had unrealized losses greater than 10% of book value with an unrealized loss of $26$27 million. The Company hasconsidered the credit quality, cash flows, interest rate movements, ability to hold a security to recovery and intent to sell a security in determining whether a security had a credit loss. The Company determined that the unrealized losses recorded as of December 31, 20162018 and December 31, 20152017 were yield related and not the result of other-than-temporary-impairment.OTTI.

 Changes in interest rates affect the value of the Company’s fixed-maturity portfolio. As interest rates fall, the fair value of fixed-maturity securities generally increases and as interest rates rise, the fair value of fixed-maturity securities generally decreases. The Company’s portfolio of fixed-maturity securities primarily consists primarily of high-quality, liquid instruments.
 

The amortized cost and estimated fair value of the Company’s available-for-sale fixed-maturity securities, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Liquidity Arrangements with respect to AGMH’s former Financial Products Business
AGMH’s former financial products segment had been in the business of borrowing funds through the issuance of GICs and medium term notes and reinvesting the proceeds in investments that met AGMH’s investment criteria. The financial products business also included the equity payment undertaking agreement portion of the leveraged lease business, as described further below in “—Leveraged Lease Business.”
The GIC Business
Until November 2008, AGMH, through its financial products business, offered GICs to municipalities and other market participants. The GICs were issued through certain non-insurance subsidiaries of AGMH. In return for an initial payment, each GIC entitles its holder to receive the return of the holder’s invested principal plus interest at a specified rate, and to withdraw principal from the GIC as permitted by its terms. AGM insures the payment obligations on all these GICs. The proceeds of GICs were loaned to AGMH’s former subsidiary FSA Asset Management LLC (FSAM). FSAM in turn invested these funds in fixed-income obligations (the FSAM assets). As of December 31, 2016, approximately 25% of the FSAM assets (measured by aggregate principal balance) were in cash or were obligations backed by the full faith and credit of the U.S. AGM’s insurance policies on the GICs remain in place, and must remain in place until each GIC is terminated, even though AGMH no longer holds any ownership interest in FSAM or the GIC issuers.
In June 2009, in connection with the Company's acquisition of AGMH from Dexia Holdings Inc., Dexia SA, the ultimate parent of Dexia Holdings Inc., and certain of its affiliates, entered into a number of agreements intended to mitigate the credit, interest rate and liquidity risks associated with the GIC business and the related AGM insurance policies. Some of those agreements have since terminated or expired, or been modified.
To support the primary payment obligations under the GICs, each of Dexia SA and Dexia Crédit Local S.A. are party to a put contract. Pursuant to the put contract, FSAM may put an amount of its FSAM assets to Dexia SA and Dexia Crédit Local S.A. in exchange for funds that FSAM would in turn make available to meet demands for payment under the GICs. To secure their obligations under this put contract, Dexia SA and Dexia Crédit Local S.A. are required to post eligible highly liquid collateral having an aggregate value (subject to agreed reductions and advance rates) equal to at least the excess of (i) the aggregate principal amount of all outstanding GICs over (ii) the aggregate mark-to-market value of FSAM’s assets.

As of December 31, 2016, the aggregate accreted GIC balance was approximately $1.5 billion, compared with approximately $10.2 billion as of December 31, 2009. As of December 31, 2016, the aggregate fair market value of the assets supporting the GIC business (disregarding the agreed upon reductions) plus cash and positive derivative value exceeded by nearly $0.8 billion the aggregate principal amount of all outstanding GICs and certain other business and hedging costs of the GIC business. Even after applying the agreed upon reductions to the fair market value of the assets, the aggregate value of the assets supporting the GIC business plus cash and positive derivative value exceeded the aggregate principal amount of all outstanding GICs and certain other business and hedging costs of the GIC business. Accordingly, no posting of collateral was required under the primary put contract.

To provide additional support, Dexia Crédit Local S.A. provides a liquidity commitment to FSAM to lend against FSAM assets under a revolving credit agreement. As of December 31, 2016, the commitment totaled $1.4 billion, of which approximately $0.8 billion was drawn. The agreement requires the commitment remain in place, generally until the GICs have been paid in full.

Despite the put contract and revolving credit agreement, and the significant portion of FSAM assets comprised of highly liquid securities backed by the full faith and credit of the United States, AGM remains subject to the risk that Dexia SA and its affiliates may not fulfill their contractual obligations. In that case, the GIC issuers may not have the financial ability to pay upon the withdrawal of GIC funds or post collateral or make other payments in respect of the GICs, thereby resulting in claims upon the AGM financial guaranty insurance policies.
A downgrade of the financial strength rating of AGM could trigger a payment obligation of AGM in respect to AGMH's former GIC business. Most GICs insured by AGM allow for the termination of the GIC contract and a withdrawal of GIC funds at the option of the GIC holder in the event of a downgrade of AGM below a specified threshold, generally below A- by S&P or A3 by Moody's. FSAM is expected to have sufficient eligible and liquid assets to satisfy any expected withdrawal and collateral posting obligations resulting from future rating actions affecting AGM.

The Medium Term Notes Business
In connection with the acquisition of AGMH, Dexia Crédit Local S.A. agreed to fund, on behalf of AGM, 100% of all policy claims made under financial guaranty insurance policies issued by AGM in relation to the medium term notes issuance program of FSA Global Funding Limited. As of December 31, 2016, FSA Global Funding Limited had approximately $560 million of medium term notes outstanding.
Leveraged Lease Business
Under the Strip Coverage Facility entered into in connection with the acquisition of AGMH, Dexia Credit Local (NY) agreed to make loans to AGM to finance all draws made by lessors on certain AGM strip policies issued in connection with the leveraged lease business. The leveraged lease business, the AGM strip policies and the Strip Coverage Facility are described further under "Commitments and Contingencies-Recourse Credit Facility" above. There have never been any borrowings under the Strip Coverage Facility, the amount of the leveraged leases covered by the Strip Coverage Facility has declined since July 1, 2009 and, to date, none of the leveraged lease transactions in which AGM acts as the strip coverage provider has experienced an early termination due to a lease default. Consequently, and in view of the credit quality of the relevant tax-exempt entities and the cost of the Strip Coverage Facility, the Company determined that maintaining the Strip Coverage Facility was no longer warranted. On July 29, 2016, the parties terminated the Strip Coverage Facility.

ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the risk of loss due to adverse changesfactors that affect the overall performance of the financial markets or moves in earnings, cash flow or fair value.market prices. The Company's primary market risk exposures in respect of market risk sensitive instruments include interest rate risk, foreign currency exchange rate risk and credit spread risk. The Company's primary exposure to market risk, is summarized below:and primarily affect the following areas.

The fair value of credit derivatives within the financial guaranty portfolio of insured obligations which fluctuate based on changes in credit spreads of the underlying obligations and the Company's own credit spreads.

The fair value of the investment portfolio is primarily driven by changes in interest rates and also affected by changes in credit spreads.

The fair value of the investment portfolio contains foreign denominated securities whose value fluctuates based on changes in foreign exchange rates.

The carrying value of premiums receivable include foreign denominated receivables whose value fluctuates based on changes in foreign exchange rates.

The fair value of the assets and liabilities of consolidated FG VIE'sVIEs may fluctuate based on changes in prepayment spreads, default rates, interest rates, and house price depreciation/appreciation. The fair value of the FG VIEVIEs’ liabilities would also fluctuate based on changes in the Company's credit spread.

Sensitivity of Credit Derivatives to Credit Risk

Unrealized gains and losses on credit derivatives are a function of changes in the estimated fair value of the Company's credit derivative contracts. If credit spreads of the underlying obligations change,and the fair value of the relatedCompany's own credit derivative changes.spread. Market liquidity could also impact valuations of the underlying obligations. The Company considers the impact of its own credit risk, together with credit spreads on the riskexposures that it insured through CDS contracts, in determining their fair value.

The Company determines its own credit risk based on quoted CDS prices traded on the Company at each balance sheet date. The quoted price of five-year CDS contracts traded on AGC at December 31, 20162018 and December 31, 20152017 was 158110 bps and 376163 bps, respectively. The quoted priceMovements in AGM's CDS prices no longer have a significant impact on the estimated fair value of five-yearthe Company's credit derivative contracts due to the run-off of CDS contracts traded on AGMexposure at December 31, 2016 and December 31, 2015 was 158 bps and 366 bps, respectively. AGM.

Historically, the price of CDS traded on AGC and AGM movesmoved directionally the same as general market spreads, although this may not always be the case. An overall narrowing of spreads generally results in an unrealized gain on credit derivatives for the Company, and an overall widening of spreads generally results in an unrealized loss for the Company. In certain circumstances, due to the fact that spread movements are not perfectly correlated, the narrowing or widening of the price of CDS traded on AGC and AGM can have a more significant financial statement impact than the changes in underlying collateral prices.risks they assume.

The impact of changes in credit spreads will vary based upon the volume, tenor, interest rates, and other market conditions at the time these fair values are determined. In addition, since each transaction has unique collateral and structural

terms, the underlying change in fair value of each transaction may vary considerably. The fair value of credit derivative contracts also reflects the change in the Company's own credit cost, based on the price to purchase credit protection on AGC and AGM.


The Company generally holds these credit derivative contracts to maturity. If events of default or termination events specified in the credit derivative documentation were to occur, the non-defaulting or the non-affected party, which may be either the Company or the counterparty, depending upon the circumstances, may decide to terminate a credit derivative prior to maturity. In that case, the Company may be required to make a termination payment to its swap counterparty upon such termination. Absent such an event of default or termination event, the Company may not unilaterally terminate a CDS contract; however, the Company on occasion has mutually agreed with various counterparties to terminate certain CDS transactions. The unrealized gains and losses on derivative financial instruments will reduce to zero as the exposure approaches its maturity date, unless there is a payment default on the exposure or early termination. Given these facts, the Company does not actively hedge these exposures.

The following table summarizes the estimated change in fair values on the net balance of the Company’s credit derivative positions assuming immediate parallel shifts in credit spreads on AGC and AGM and on the risks that they both assume.

Sensitivity of Investment Portfolio to Interest Rate Risk

Interest rate risk is the risk that financial instruments' values will change due to changes in the level of interest rates, in the spread between two rates, in the shape of the yield curve or in any other interest rate relationship. The Company is exposed to interest rate risk primarily in its investment portfolio. As interest rates rise for an available-for-sale investment portfolio, the fair value of fixed‑income securities generally decreases; as interests rates fall for an available-for-sale portfolio, the fair value of fixed-income securities generally increases. The Company's policy is generally to hold assets in the investment portfolio to maturity. Therefore, barring credit deterioration, interest rate movements do not result in realized gains or losses unless assets are sold prior to maturity. The Company does not hedge interest rate risk, however,risk; instead, interest rate fluctuation risk is managed through the investment guidelines which limit duration and preventprohibit investment in historically high volatility sectors.

Interest rate sensitivity in the investment portfolio can be estimated by projecting a hypothetical instantaneous increase or decrease in interest rates. The following table presents the estimated pre-tax change in fair value of the Company's fixed-maturity securities and short-term investments from instantaneous parallel shifts in interest rates.

Sensitivity of Other Areas to Interest Rate Risk

Insurance

Fluctuation in interest rates also affects the demand for the Company's product. When interest rates are lower or when the market is otherwise relatively less risk averse, the spread between insured and uninsured obligations typically narrows and, as a result, financial guaranty insurance typically provides lower cost savings to issuers than it would during periods of relatively wider spreads. These lower cost savings generally lead to a corresponding decrease in demand and premiums obtainable for financial guaranty insurance. Changes in interest rates also impact the amount of our losses and could impact the amount of infrastructure exposures that can be refinanced in the future. In addition, increases in prevailing interest rate levels can lead to a decreased volume of capital markets activity and, correspondingly, a decreased volume of insured transactions.

In addition, fluctuations in interest rates also impact the performance of insured transactions where there are differences between the interest rates on the underlying collateral and the interest rates on the insured securities. For example, a rise in interest rates could increase the amount of losses the Company projects for certain RMBS, Triple-X life insurance securitizations, and student loan transactions and TruPS CDOs.transactions. The impact of fluctuations in interest rates on such transactions varies, depending on, among other things, the interest rates on the underlying collateral and insured securities, the relative amounts of underlying collateral and liabilities, the structure of the transaction, and the sensitivity to interest rates of the behavior of the underlying borrowers and the value of the underlying assets.

In the case of RMBS, fluctuations in interest rates impact the amount of periodic excess spread, which is created when a trust’s assets produce interest that exceeds the amount required to pay interest on the trust’s liabilities. There are several RMBS transactions in ourthe Company's insured portfolio which benefit from excess spread either by covering losses in a particular period, or reimbursing past claims under ourthe Company's policies. As of December 31, 2016,2018, the Company projects approximately $225$148 million of excess spread for all of its RMBS transactions over their remaining lives.

Since RMBS excess spread is determined by the relationship between interest rates on the underlying collateral and the trust’s certificates, it can be affected by unmatched moves in either of these interest rates.  Additionally, faster than expected prepayments can decrease the dollar amount of excess spread and therefore reduce the cash flow available to cover losses or reimburse past claims.  Further,For example, modifications to underlying mortgage rates (e.g. rate reductions for troubled borrowers) can reduce excess spread since there would be no equivalent decrease in the certificate interest rates of the trust's certificates.liabilities. Similarly, an upswing in short-term rates that increases the trust’s certificate interest rate that is not met with equal increases to the interest rates on the underlying mortgages can decrease excess spread.  These potential reductions in excess spread are often mitigated by an interest rate cap, which goes into effect once the collateral rate falls below the stated certificate rate. MostInterest due on most of the RMBS securities we insurethe Company insures are capped at the collateral rate. The Company is not obligated to pay additional claims becausewhen the collateral interest rate drops below the trust's certificate stated interest rate, rather this just causes the Company to lose the benefit of potential positive excess spread. Additionally, faster than expected prepayments can decrease the dollar amount of excess spread and therefore reduce the cash flow available to cover losses or reimburse past claims.

Interest Expense

Beginning in the fourth quarter of 2016, fluctuationfluctuations in interest rates also impacts the Company’s interest expense.  On December 15, 2016, the series A enhanced junior subordinated debentures issued by AGUS began to accrue interest at a floating rate, reset quarterly, equal to three month London Interbank Offered Rate (3-month LIBOR)three-month LIBOR plus a margin equal to 2.38% (prior to December 15, 2016, the debentures paid a fixed 6.4% rate of interest).  The 3-monththree-month LIBOR rate of 2.79% and 1.59% were used for the interest rate resets for December 15, 2016 interest rate reset is 0.96%.2018 and December 15, 2017, respectively.  Increases to 3-monththree-month LIBOR will cause the Company’s interest expense to rise while decreases to 3-monththree month LIBOR will lower the Company’s interest expense.  If 3-monthFor example, if three-month LIBOR increases by 70%,100 bps, the Company’s annual interest expense will increase by approximately $1$1.5 million.  Conversely, if 3-monththree-month LIBOR decreases by 70%,100 bps, the Company’s annual interest expense will decrease by approximately $1$1.5 million. LIBOR may be discontinued. See the Risk Factor captioned "The Company may be adversely impacted by the transition from LIBOR as a reference rate" under Risks Related to the Financial, Credit and Financial Guaranty Markets in Part I, Item 1A, Risk Factors.



Sensitivity of Investment Portfolio to Foreign Exchange Rate Risk

Foreign exchange risk is the risk that a financial instrument's value will change due to a change in the foreign currency exchange rates. The Company has foreign denominated securities in its investment portfolio. Securities denominated in currencies other than U.S. Dollar were 4.7% and 4.9% of the fixed-maturity securities and short-term investmentsportfolio as of December 31, 2016 and 2015, respectively. The Company's material exposure is to changes in the dollar/pound sterling exchange rate. Changes in fair value of available-for-sale investments attributable to changes in foreign exchange rates are recorded in OCI.

Sensitivity of Premiums Receivable to Foreign Exchange Rate Risk

The Company haswell as foreign denominated premium receivables. The Company's material exposure is to changes in dollar/pound sterling and dollar/euro exchange rates. Securities denominated in currencies other than U.S. Dollar were 7.4% and 7.6% of the fixed-maturity securities and short-term investments as of December 31, 2018 and 2017, respectively. Changes in fair value of available-for-sale investments attributable to changes in foreign exchange rates are recorded in OCI. The increase in the sensitivity to movements in foreign exchange rates for premium receivables in 2017 is primarily due to the acquisition of MBIA UK.

Sensitivity of FG VIEVIEs’ Assets and Liabilities to Market Risk

The fair value of the Company’s FG VIEVIEs’ assets is generally sensitive to changes related to estimated prepayment speeds; estimated default rates (determined on the basis of an analysis of collateral attributes such as: historical collateral performance, borrower profiles and other features relevant to the evaluation of collateral credit quality); discount ratesyields implied by market prices for similar securities; and house price depreciation/appreciation rates based on macroeconomic forecasts. Significant changes to some of these inputs could materially change the market value of the FG VIE’sVIEs’ assets and the implied collateral losses within the transaction. In general, the fair value of the FG VIE assetVIEs’ assets is most sensitive to changes in the projected collateral losses, where an increase in collateral losses typically leads to a decrease in the fair value of FG VIEVIEs’ assets, while a decrease in collateral losses typically leads to an increase in the fair value of FG VIEVIEs’ assets. These factors also directly impactThe third-party utilizes an internal model to determine an appropriate yield at which to discount the cash flows of the security, by factoring in collateral types, weighted-average lives, and other structural attributes specific to the security being priced. The expected yield is further calibrated by utilizing algorithms designed to aggregate market color, received by the independent third-party, on comparable bonds.

The models to price the FG VIEs’ liabilities used, where appropriate, the same inputs used in determining fair value of FG VIEs’ assets and, for those liabilities insured by the Company’s FG VIE liabilities.Company, the benefit from the Company's insurance policy guaranteeing the timely payment of principal and interest, taking into account the Company's own credit risk.
 
The fair value of the Company’s FG VIE liabilities is generally sensitive to the various model inputs described above. In addition, the Company’s FG VIE liabilities with recourse are also sensitive to changes in the Company’s implied credit worthiness. Significant changes to any of thesethe inputs described above could materially change the timing of expected losses within the insured transaction which is a significant factor in determining the implied benefit from the Company’s insurance policy guaranteeing the timely payment of principal and interest for the tranches of debt issued by the FG VIEVIEs that is insured by the Company. In general, extending the timing of expected loss payments by the Company into the future typically leads to a decrease in the value of the Company’s insurance and a decrease in the fair value of the Company’s FG VIEVIEs’ liabilities with recourse, while a shortening of the timing of expected loss payments by the Company typically leads to an increase in the value of the Company’s insurance and an increase in the fair value of the Company’s FG VIEVIEs’ liabilities with recourse.

COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management'sManagement’s Report on Internal Control over Financial Reporting.Reporting appearing under Item 9A. Our responsibility is to express opinions on these the Company’s consolidatedfinancial statements and on the Company's internal control over financial reporting based on our integrated audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidatedfinancial statements included performing procedures to assess the risks of material misstatement of the consolidatedfinancial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence supportingregarding the amounts and disclosures in the consolidatedfinancial statements, assessingstatements. Our audits also included evaluating the accounting principles used and significant estimates made by management, andas well as evaluating the overall presentation of the consolidated financial statement presentation.statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.


Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements
 
December 31, 2016, 20152018, 2017 and 2014 2016 

1.Business and Basis of Presentation
 
Business
 
Assured Guaranty Ltd. (AGL and, together with its subsidiaries, Assured Guaranty or the Company) is a Bermuda-based holding company that provides, through its operating subsidiaries, credit protection products to the United States (U.S.) and international public finance (including infrastructure) and structured finance markets. The Company applies its credit underwriting judgment, risk management skills and capital markets experience primarily to offer financial guaranty insurance that protects holders of debt instruments and other monetary obligations from defaults in scheduled payments. If an obligor defaults on a scheduled payment due on an obligation, including a scheduled principal or interest payment (debt service), the Company is required under its unconditional and irrevocable financial guaranty to pay the amount of the shortfall to the holder of the obligation. The Company markets its financial guaranty insurance directly to issuers and underwriters of public finance and structured finance securities as well as to investors in such obligations. The Company guarantees obligations issued principally in the U.S. and the United Kingdom (U.K.), and also guarantees obligations issued in other countries and regions, including Australia and Western Europe. The Company also provides other forms of insurance (non-financial guaranty insurance) that are in line with its risk profile and benefit from its underwriting experience.

In the past, the Company sold credit protection by issuing policies that guaranteed payment obligations under credit derivatives, primarily credit default swaps (CDS). Contracts accounted for as credit derivatives are generally structured such that the circumstances giving rise to the Company’s obligation to make loss payments are similar to those for financial guaranty insurance contracts. The Company’s credit derivative transactions are governed by International Swaps and Derivative Association, Inc. (ISDA) documentation. The Company has not entered into any new CDS in order to sell credit protection in the U.S. since the beginning of 2009, when regulatory guidelines were issued that limited the terms under which such protection could be sold. The capital and margin requirements applicable under the Dodd-Frank Wall Street Reform and Consumer Protection Act also contributed to the Company not entering into such new CDS in the U.S. since 2009. The Company actively pursues opportunities to terminate existing CDS, which have the effect of reducing future fair value volatility in income and/or reducing rating agency capital charges.

Basis of Presentation
 
The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) and, in the. In management's opinion, of management, reflect all material adjustments that are of a normal recurring nature, necessary for a fair statement of the financial condition, results of operations and cash flows of the Company and its consolidated variable interest entities (VIEs) forare reflected in the periods presented.presented and are of a normal, recurring nature. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The 2016 financial information in Note 21, Subsidiary Information, reflects transfers of businesses between entities within the consolidated group that occurred in 2017, consistently for all prior periods presented. The presentation of cash flow amounts related to short-term investments was changed during 2018 to reflect cash flows on a gross, rather than a net, basis.

The consolidated financial statements include the accounts of AGL, its direct and indirect subsidiaries (collectively, the Subsidiaries), and its consolidated VIEs. Intercompany accounts and transactions between and among all consolidated entities have been eliminated. Certain prior-yearprior year balances have been reclassified to conform to the current year's presentation.

The Company's principal insurance company subsidiaries are:

Assured Guaranty Municipal Corp. (AGM), domiciled in New York;
Municipal Assurance Corp. (MAC), domiciled in New York;
Assured Guaranty Corp. (AGC), domiciled in Maryland;
Assured Guaranty (Europe) Ltd.plc (AGE), organized in the U.K.; and
Assured Guaranty Re Ltd. (AG Re), domiciled in Bermuda; and

Future Application ofAdopted Accounting Standards

Income TaxesChanges to the Disclosure Requirements for Fair Value Measurement

In October 2016,August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-16, Income Taxes2018-13, Fair Value Measurement (Topic 740)820): Disclosure Framework - Intra-Entity Transfers of Assets Other Than Inventory, which removes the current prohibition against immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory.  Under the ASU, the selling (transferring) entity is required to recognize a current income tax expense or benefit upon transfer of the asset.  Similarly, the purchasing (receiving) entity is required to recognize a deferred tax asset or deferred tax liability, as well as the related deferred tax benefit or expense, upon receipt of the asset.  The ASU is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, and early adoption is permitted.  The ASU’s amendments are to be applied on a modified retrospective basis recognizing the effects in retained earnings as of the beginning of the year of adoption.  The Company is currently evaluating the effect on its Consolidated Financial Statements of adopting this ASU.

Statement of Cash Flows

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the Emerging Issues Task Force), which addresses the presentation of changes in restricted cash and restricted cash equivalents in the statement of cash flows with the objective of reducing the existing diversity in practice. Under the ASU, entities are required to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows.  As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows.  When cash, cash equivalents, restricted cash and restricted cash equivalents are presented in more than one line item on the balance sheet, the ASU requires a reconciliation be presented either on the face of the statement of cash flows or in the notesChanges to the financial statements showing the totals in the statement of cash flows to the related captions in the balance sheet. The ASU is effectiveDisclosure Requirements for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including

adoption in an interim period. If the ASU is adopted in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. This ASU will not have a material impact on the Company’s Consolidated Statements of Cash Flows.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force), which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The issues addressed in the new guidance include debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investments, beneficial interests in securitization transactions and separately identifiable cash flows and application of the predominance principle. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. This ASU will not have a material impact on the Company’s Consolidated Statements of Cash Flows.

Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326):Fair Value Measurement of Credit Losses on Financial Instruments.  The amendments in this ASU are intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions will use forward-looking information to better inform their credit loss estimates as a result of the ASU. While many of the loss estimation techniques applied today will still be permitted, the inputs to those techniques will change to reflect the full amount of expected credit losses. The ASU requires enhanced disclosures to help investors and other financial statement users to better understand significant estimates and judgments used in estimating credit losses, as well as credit quality and underwriting standards of an organization’s portfolio. 

In addition, the ASU amends the accounting for credit losses on available-for-sale securities and purchased financial assets with credit deterioration. The ASU also eliminates the concept of “other than temporary” from the impairment model for certain available-for-sale securities. Accordingly, the ASU states that an entity must use an allowance approach, must limit the allowance to an amount at which the security’s fair value is less than its amortized cost basis, may not consider the length of time fair value has been less than amortized cost, and may not consider recoveries in fair value after the balance sheet date when assessing whether a credit loss exists. For purchased financial assets with credit deterioration, the ASU requires an entity’s method for measuring credit losses to be consistent with its method for measuring expected losses for originated and purchased non-credit-deteriorated assets.

The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. For most debt instruments, entities will be required to record a cumulative-effect adjustment to the statement of financial position as of the beginning of the first reporting period in which the guidance is adopted.  The changes to the impairment model for available-for-sale securities and changes to purchased financial assets with credit deterioration are to be applied prospectively.  For the Company, this would be as of January 1, 2020.  Early adoption is permitted for fiscal years, and interim periods with those fiscal years, beginning after December 15, 2018.  The Company is currently evaluating the effect on its Consolidated Financial Statements of adopting this ASU.

Share-Based Payments

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment, which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows.  The new guidance will require all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. It also will allow an employer to repurchase more of an employee’s shares than it can today for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur.  The ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years, and early adoption is permitted.  The Company does not expect that the ASU will have a material effect on its Consolidated Financial Statements.


Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).  This ASU requires lessees to present right-of-use assetsremoved, modified and lease liabilitiesadded additional disclosure requirements on the balance sheet. ASU 2016-02 is to be applied using a modified retrospective approach at the beginning of the earliest comparative periodfair value measurements in the financial statements. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted.Topic 820. The Company is evaluating the impact thathas adopted this ASU will have on its Consolidated Financial Statements.as of December 31, 2018 with the relevant disclosure updates included in Note 7, Fair Value Measurements.

Financial Instruments

In January 2016, the FASB issued ASU 2016-01,Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities.  The amendments in this ASU are intended to make targeted improvements to GAAP by addressing certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. UnderAmendments under this ASU apply to the ASU,Company's financial guaranty variable interest entities’ (FG VIEs’)

liabilities, which the Company has historically elected to measure through the statement of operations under the fair value option, and to certain equity securities will needin the Company’s investment portfolio.

For FG VIEs’ liabilities with recourse, the portion of the change in fair value caused by changes in instrument-specific credit risk (ISCR) (i.e., in the case of FG VIEs’ liabilities, the Company's own credit risk) must now be separately presented in OCI as opposed to bethe statement of operations. See Note 9, Variable Interest Entities for additional information.

Amendments under this ASU also apply to equity securities, except those that are accounted for under the equity method of accounting or that resulted in consolidation of the investee by the Company. For equity securities accounted for at fair value, with changes in fair value recognized through net income.  Currently,that previously were recorded in OCI are now recorded in other income in the consolidated statements of operations effective January 1, 2018. Equity securities carried at cost as of December 31, 2017, are now recorded at cost less impairment plus or minus the change resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Such changes are recorded in the statement of operations. See Note 10, Investments and Cash for additional information.

On January 1, 2018, the Company recognizes unrealized gainsadopted this ASU resulting in a cumulative-effect reclassification of a $32 million loss, net of tax, from retained earnings to accumulated OCI (AOCI).

Income Taxes

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory, which removed the prohibition against immediate recognition of the current and lossesdeferred income tax effects of intra-entity transfers of assets other than inventory.  Under the ASU, the selling (transferring) entity is required to recognize a current income tax expense or benefit upon transfer of the asset.  Similarly, the purchasing (receiving) entity is required to recognize a deferred tax asset or deferred tax liability, as well as the related deferred tax benefit or expense, upon receipt of the asset. The ASU was adopted on January 1, 2018 with no material effect on the consolidated financial statements.

Future Application of Accounting Standards

Premium Amortization on Purchased Callable Debt Securities

In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Topic 310-20) - Premium Amortization on Purchased Callable Debt Securities.  This ASU shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date.  This ASU has no effect on the accounting for purchased callable debt securities held at a discount.  It is to be applied using a modified retrospective approach and the ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. This ASU will have no effect on the Company's consolidated financial statements.

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). Subsequent to the issuance of this ASU, Topic 842 was amended by various updates that clarified the impact and implementation of ASU 2016-02. Collectively, these securitiesupdates will require lessees to present right-of-use assets and lease liabilities on the balance sheet.  The Company currently accounts for its lease agreements, where the Company is the lessee, as operating leases and, therefore, does not record these leases on its consolidated balance sheet.  Upon adoption on January 1, 2019, the Company will report an increase in OCI. Another amendment pertains toboth assets and liabilities that an entity has elected to measure at fair value in accordance with the fair value option for financial instruments. For these liabilities, the portion of fair value changeapproximately $69 million primarily related to the Company's office space leases.

Credit Losses on Financial Instruments

  In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.  The ASU provides a new current expected credit risk will be separately presented in OCI.  Currently, the entire change in the fair value of these liabilities is reflected in the income statement. The Company elected the fair value optionloss model to account for its consolidated FG VIEs. FG VIEcredit losses on certain financial liabilities with recourse are sensitiveassets and off-balance sheet exposures (e.g., reinsurance recoverables, premium receivables, held-to- maturity debt securities, and loan commitments). That model requires an entity to changesestimate lifetime credit losses related to certain financial assets, based on relevant historical information, adjusted for current conditions and reasonable and supportable forecasts that could affect the collectability of the reported amount. The ASU also makes targeted amendments to the current impairment model for available-for-sale debt securities, which includes requiring the recognition of an allowance rather than a direct write-down of the investment. The allowance may be reversed in the Company’s impliedevent that the credit worthinessof an issuer improves. In addition, the ASU eliminates the existing guidance for purchased credit impaired assets and will be impacted byintroduces a new model for

purchased financial assets with credit deterioration, such as the ASU. Company's loss mitigation securities. That new model would require the recognition of an initial allowance for credit losses, which is added to the purchase price.

                The ASU is effective for fiscal years, and interim period within those fiscal years, beginning after December 15, 2017, including interim periods within those fiscal years. Entities2019. For reinsurance recoverables, premiums receivable and debt instruments such as loans and held to maturity securities, entities will be required to record a cumulative-effect adjustment to the statement of financial position as of the beginning of the fiscal yearfirst reporting period in which the guidance is adopted. ForThe changes to the Company, this wouldimpairment model for available-for-sale securities and changes to purchased financial assets with credit deterioration are to be as of January 1, 2018.applied prospectively. Early adoption of the amendments is permitted only forpermitted. The Company does not plan to early adopt this ASU. The Company is evaluating the amendment relatedeffect that this ASU will have on its financial statements.

Targeted Improvements to the changeAccounting for Long-Duration Contracts

In August 2018, the FASB issued ASU 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts.  The amendments in presentationthis ASU:

improve the timeliness of recognizing changes in the liability for future policy benefits and modify the rate used to discount future cash flows,
simplify and improve the accounting for certain market-based options or guarantees associated with deposit (or account balance) contracts,
simplify the amortization of deferred acquisition costs, and
improve the effectiveness of the required disclosures.

This ASU does not impact the Company’s financial liabilities that are fair valued usingguaranty insurance contracts, but may impact its accounting for certain non-financial guaranty contracts. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption of the fair value option.amendments is permitted. The Company does not expect that the amendment relatedthis ASU to certain equity securities will have a material effect on its Consolidated Financial Statements. Upon the adoption date, the Company will present the total change in credit risk for FG VIEs’consolidated financial liabilities with recourse separately in OCI. statements.

2.AcquisitionsAssumption of Insured Portfolio and Business Combinations

Consistent with one of its key business strategies of supplementing its book of business through acquisitions of legacy financial guaranty companies or their portfolios, the Company has acquired threetwo financial guaranty companies and completed one reinsurance transaction, since January 1, 2015,2016, as described below.

CIFG HoldingReinsurance of Syncora Guarantee Inc.
On July 1, 2016, AGC acquired all of the issued and outstanding capital stock of CIFG Holding Inc. (together with its subsidiaries CIFGH), the parent of financial guaranty insurer CIFG Assurance North America, Inc. (CIFGNA), (the CIFG Acquisition), for $450.6 million in cash. AGUS previously owned 1.6% of the outstanding shares of CIFGH, for which it received $7.1 million in consideration from AGC, resulting in a net consolidated purchase price of $443 million. AGC merged CIFGNA with and into AGC, with AGC as the surviving company, on July 5, 2016. The CIFG Acquisition added $4.2 billion of net par insured on July 1, 2016.’s Insured Portfolio

AtOn June 1, 2018, the timeCompany closed a reinsurance transaction (SGI Transaction) with Syncora Guarantee Inc. (SGI) under which AGC assumed, generally on a 100% quota share basis, substantially all of SGI’s insured portfolio and AGM reassumed a book of business previously ceded to SGI by AGM. As of June 1, 2018, the net par value of exposures reinsured and commuted totaled approximately $12 billion (including credit derivative net par of approximately $1.5 billion). The reinsured portfolio consists predominantly of public finance and infrastructure obligations that meet AGC’s underwriting criteria and generated $330 million of gross written premiums. On June 1, 2018, as consideration, SGI paid $363 million and assigned to Assured Guaranty financial guaranty future insurance installment premiums of $45 million, and future credit derivative installments of approximately $17 million. The assumed portfolio from SGI included below-investment-grade (BIG) contracts which had, as of June 1, 2018, expected losses to be paid of $131 million (present value basis using risk free rates), which will be expensed over the expected terms of those contracts as unearned premium reserve amortizes. In connection with the SGI Transaction, the Company incurred and expensed $4 million in fees to professional advisors.


The effect of the CIFG Acquisition, CIFGNA had a subsidiary financial guaranty company domiciled in France, CIFG Europe S.A. (CIFGE), which had been put into run-offSGI Transaction on the insurance and surrendered its licenses.

Additionally, beginning on June 1, 2018, on behalf of SGI, AGC began providing certain administrative services on the assumed portfolio, including surveillance, risk management, and also had issued a “second-to-pay policy” pursuant to which CIFGNA guaranteed the full and complete payment of any shortfall in amounts due from CIFGE on its insured portfolio; AGC assumed these obligations as part of the CIFGNA merger with and into AGC. CIFGE remains a separate subsidiary in runoff, now owned by AGC. As of December 31, 2016, CIFGE had investment assets of $41 million and gross par exposure of $694 million, and is not currently expected to pay dividends.claims processing.

Accounting Policies

The CIFG Acquisition wasacquisitions were accounted for under the acquisition method of accounting which requires that the assets and liabilities acquired be recorded at fair value. The Company exercised significant judgment to determine the fair value of the assets it acquired and liabilities it assumed in each of the CIFG Acquisition.acquisitions. The most significant of these determinations related to the valuation of CIFGH'sthe acquired financial guaranty insurance and credit derivative contracts. On an aggregate basis, CIFGH'sthe acquired companies' contractual premiums for financial guaranty insurance contracts acquired were less than the premiums a market participant of similar credit quality would demand to acquire those contracts at the date of the CIFG Acquisition (the CIFG Acquisition Date), particularlyacquisition (particularly for below-investment-grade transactions,BIG transactions) resulting in a significant amount of the purchase price being allocated to these contracts. For information on the methodology the Company used to measure the fair value of assets it acquired and liabilities it assumed in

the CIFG Acquisition, including financial guaranty insurance and credit derivative contracts, please refer toacquisitions, see Note 7, Fair Value Measurement.

The fair value of the Company's stand-ready obligation on the CIFG Acquisition Datedate of acquisition is recorded in unearned premium reserve. After the CIFG Acquisition Date,Thereafter, loss reserves and loss and loss adjustment expenses (LAE) will beare recorded when the expected losses for each contract exceeds the remaining unearned premium reserve, in accordance with the Company's accounting policy described in Note 6, Contracts Accounted for as Insurance. The expected losses acquired by the Company as part of the CIFG Acquisition are included in the description of expected losses to be paid under Note 5, Expected Losses to be Paid.insurance or credit derivatives, depending on each contract's characteristics.

The excess of the fair value of net assets acquired over the consideration transferred was recorded, in each acquisition, as a bargain purchase gain in "bargain purchase gain and settlementthe statement of pre-existing relationships" in net income.operations. In addition, the Company and CIFGHeach of the acquired companies had pre-existing reinsurance relationships, which were also effectively settled at fair value on the CIFG Acquisition Date.their respective acquisition dates. The gain or loss on settlement of these pre-existing reinsurance relationships represents the net difference between the historical assumed or ceded balances that were recorded by AGCthe Company and the fair value of ceded or assumed balances acquired from CIFGH. The Company believesand was also recorded in the bargain purchase gain resulted fromstatement of operations.

MBIA UK Insurance Limited

AGC completed its acquisition of MBIA UK Insurance Limited (MBIA UK) (the MBIA UK Acquisition), the natureU.K. operating subsidiary of MBIA Insurance Corporation (MBIA) on January 10, 2017 (the MBIA UK Acquisition Date). As consideration for the financial guaranty businessoutstanding shares of MBIA UK plus $23 million in cash, AGC exchanged all its holdings of notes issued in the Zohar II 2005-1 transaction (Zohar II Notes), which were insured by MBIA. AGC’s Zohar II Notes had total outstanding principal of approximately $347 million and the desire of investors in CIFGH to monetize their investments in CIFGH. The bargain purchase gain reflects the fair value of CIFGH’s assets$334 million as of the MBIA UK Acquisition Date. The MBIA UK Acquisition added approximately $12 billion of net par insured on January 10, 2017.

MBIA UK was renamed Assured Guaranty (London) Ltd. and liabilities,on June 1, 2017, was re-registered as well as tax attributes that were recorded in deferred taxes comprising net operating losses (after Internal Revenue Code change in control provisions)a public limited company (plc). In a multi-step business combination completed on November 7, 2018, it ultimately transferred its insurance portfolio to and other temporary book-to-tax differencesmerged with and into AGE.

Revenue and net income (excluding the effects of subsequent tax reform) related to CIFGHMBIA UK from the CIFGMBIA UK Acquisition Date through December 31, 20162017 included in the consolidated statement of operations were approximately $307$192 million and $323$139 million, respectively.respectively, including the bargain purchase gain, settlement of pre-existing relationships, activity during the year and realized gain on the disposition of AGC's Zohar II Notes. For 2016,2017, the Company recognized transaction expenses related to the CIFG Acquisition.

Radian Asset Assurance Inc.

On April 1, 2015 (Radian Acquisition Date), AGC completed the acquisition (Radian Asset Acquisition) of all of the issued and outstanding capital stock of financial guaranty insurer Radian Asset Assurance Inc. (Radian Asset) for $804.5 million; the cash consideration was paid from AGC's available funds and from the proceeds of a $200 million loan from AGC’s direct parent, AGUS. AGC repaid the loan in full to AGUS on April 14, 2015. Radian Asset was merged with and into AGC, with AGC as the surviving company of the merger. The Radian Asset Acquisition added $13.6 billion to the Company's net par outstanding on April 1, 2015.

The Radian Asset Acquisition was accounted for under the acquisition method of accounting which required that the assets and liabilities acquired be recorded at fair value. The Company was required to exercise significant judgment to determine the fair value of the assets it acquired and liabilities it assumed in the Radian Asset Acquisition. The most significant of these determinations related to the valuation of Radian Asset's financial guaranty insurance and credit derivative contracts. On an aggregate basis, Radian Asset’s contractual premiums for financial guaranty contracts were less than the premiums a market participant of similar credit quality would demand to acquire those contracts at the Radian Acquisition Date, particularly for below-investment-grade (BIG) transactions, resulting in a significant amount of the purchase price being allocated to these contracts. For information on the methodology the Company used to measure the fair value of assets it acquired and liabilities it assumed in the Radian Asset Acquisition, including financial guaranty insurance and credit derivative contracts, please refer to Note 7, Fair Value Measurement.

The fair value of the Company's stand-ready obligation for financial guaranty insurance contracts on the Radian Acquisition Date is recorded in unearned premium reserve (please refer to Note 6, Contracts Accounted for as Insurance for additional information on stand-ready obligation). At the Radian Acquisition Date, the fair value of each financial guaranty insurance contract acquired was in excess of the expected losses for each contract and therefore no explicit loss reserves were recorded on the Radian Acquisition Date. Loss reserves and loss and LAE are recorded when the expected losses for each contract exceeds the remaining unearned premium reserve, in accordance with the Company's accounting policy described in Note 6, Contracts Accounted for as Insurance. The expected losses assumed by the Company as part of the Radian Asset Acquisition are included in the description of expected losses to be paid under Note 5, Expected Loss to be Paid.

The excess of the fair value of net assets acquired over the consideration transferred was recorded as a bargain purchase gain in "bargain purchase gain and settlement of pre-existing relationships" in net income. In addition, the Company and Radian Asset had pre-existing reinsurance relationships, which were effectively settled at fair value on the Radian Acquisition Date. The gain on settlement of these pre-existing reinsurance relationships primarily represents the net difference between the historical ceded balances that were recorded by AGM and the fair value of assumed balances acquired from Radian Asset. The Company believes the bargain purchase resulted from the announced desire of Radian Guaranty Inc. to focus its business strategy on the mortgage and real estate markets and to monetize its investment in Radian Asset and thereby accelerate its ability to comply with the financial requirements of the final Private Mortgage Insurer Eligibility Requirements.


The following table shows the net effect of the Radian Asset Acquisition at the Radian Acquisition Date, including the effects of the settlement of pre-existing relationships.

3.(1)Rating ActionsThe cash purchase price of $443 million represents the cash transferred for the acquisition which was allocated as follows: (1) $270 million for the purchase of net assets of $627 million, and (2) the settlement of pre-existing relationships between CIFGH and Assured Guaranty at a fair value of $173 million.

WhenThe bargain purchase gain reflects the fair value of CIFG’s assets and liabilities, as well as tax attributes that were recorded in deferred taxes related to net operating losses (NOL) (after Internal Revenue Code change in control provisions) and other temporary book-to-tax differences for which CIFG had recorded a rating agency assignsfull valuation allowance. The Company believes the bargain purchase gain resulted from the nature of the financial guaranty business and the desire of investors in CIFG to monetize their investments in CIFG.

Revenue and net income related to CIFG from the CIFG Acquisition Date through December 31, 2016 included in the consolidated statement of operations were approximately $307 million and $323 million, respectively. For 2016, the Company recognized transaction expenses related to the CIFG Acquisition of $6 million, primarily consisting of legal and financial advisors fees.

The Company has determined that the presentation of pro forma information is impractical for the CIFG Acquisition as historical financial records are not available on a public rating to aU.S. GAAP basis.


3.    Ratings
The financial obligation guaranteed by one ofstrength ratings (or similar ratings) for AGL’s insurance company subsidiaries, it generally awards that obligationalong with the same rating it has assigned to the financial strengthdate of the AGL subsidiary that provides the guaranty. Investors in products insured by AGL’s insurance company subsidiaries frequently rely on ratings publishedmost recent rating action (or confirmation) by the rating agencies because such ratings influenceagency, are shown in the trading value of securities and form the basis for many institutions’ investment guidelines as well as individuals’ bond purchase decisions. Therefore, the Company manages its business with the goal of achieving strong financial strength ratings. However, the methodologies and models used by rating agencies differ, presenting conflicting goals that may make it inefficient or impractical to reach the highest rating level. The methodologies and models are not fully transparent, contain subjective elements and data (such as assumptions about future market demand for the Company’s products) and may change.table below. Ratings are subject to continuous rating agency review and revision or withdrawal at any time. IfIn addition, the financial strength ratings of one (or more) of the Company’s insurance subsidiaries were reduced below current levels, the Company expects it could have adverse effects on the impacted subsidiary's future business opportunities as well as the premiums the impacted subsidiary could charge for its insurance policies.     

The Company periodically assesses the value of each rating assigned to each of its companies, and as a result of such assessment may request that a rating agency add or drop a rating from certain of its companies. For example, the Kroll Bond Rating Agency (KBRA) ratings were first assigned to MAC in 2013, to AGM in 2014, and to AGC in 2016, while the A.M. Best Company, Inc. (Best) rating was first assigned to Assured Guaranty Re Overseas Ltd. (AGRO) in 2015, and a Moody's Investors Service, Inc. (Moody's) rating was never requested for MAC and was dropped from AG Re and AGRO in 2015. On January 13, 2017, AGC announced that it had requested that Moody's withdraw its financial strength rating of AGC.

In the last several years, S&P Global Ratings, a division of Standard & Poor's Financial Services LLC (S&P) and Moody's have changed, multiple times, their financial strength ratings of AGL's insurance subsidiaries, or changed the outlook on such ratings. More recently, KBRA and Best have assigned financial strength ratings to some of AGL's insurance subsidiaries. The rating agencies' most recent actions related to AGL's insurance subsidiaries are:

(2)As a result of the Combination, each of S&P Global Ratings, a division of Standard & Poor’s Financial Services LLC (S&P), and Moody’s withdrew their ratings on AGLN and AGUK.

On September 20, 2016, KBRA assigned a financial strength rating of AA (stable outlook) to AGC. On December 14, 2016 and July 8, 2016, KBRA affirmed the AA+ (stable outlook) financial strength ratings of AGM and MAC, respectively.

On August 8, 2016, Moody's affirmed the A2 (stable outlook) on AGM and AGE and A3 insurance financial strength rating on AGC and AGC's subsidiary Assured Guaranty (U.K.) Ltd. (AGUK) raising the outlook to stable from negative, although AGC has requested that Moody's withdraw its financial strength rating of AGC and AGUK. Effective April 8, 2015, at the Company's request, Moody’s withdrew the financial strength ratings it had assigned to AG Re and AGRO.

On July 27, 2016, S&P affirmed the AA (stable) financial strength ratings of AGL's insurance subsidiaries.

On May 27, 2016, Best affirmed the A+ (stable) financial strength rating, which is their second highest rating, of AGRO.

and Note 13, Reinsurance and Other Monoline ExposuresReinsurance.

4.Outstanding Exposure
 
The Company’sCompany primarily writes financial guaranty contracts are written in either insurance orform. Until 2009, the Company also wrote some of its financial guaranty contracts in credit derivative form, but collectively are consideredand has acquired or reinsured portfolios both before and after 2009 that include financial guaranty contracts in credit derivative form. Whether written as an insurance contract or as a credit derivative, the Company considers these financial guaranty contracts. The Company also writes a relatively small amount of non-financial guaranty insurance.

The Company seeks to limit its exposure to losses by underwriting obligations that it views as investment grade at inception, although on occasion it may underwrite new issuances that it views as BIG, typically as part of its loss mitigation strategy for existing troubled credits,exposures. The Company also seeks to acquire portfolios of insurance from financial guarantors that are no longer writing new business by acquiring such companies, providing reinsurance on a portfolio of insurance or reassuming a portfolio of reinsurance it had previously ceded; in such instances, it evaluates the risk characteristics of the target portfolio, which may underwrite new issuances that it viewsinclude some BIG exposures, as BIG.a whole in the context of the proposed transaction. The Company diversifies its insured portfolio across asset classes and, in the structured finance portfolio, typically requires rigorous subordination or collateralization requirements.collateral to protect it from loss. Reinsurance may be used in order to reduce net exposure to certain insured transactions.

     Public finance obligations insured by the Company primarily consist primarily of general obligation bonds supported by the taxing powers of U.S. state or municipal governmental authorities, as well as tax-supported bonds, revenue bonds and other obligations supported by covenants from state or municipal governmental authorities or other municipal obligors to impose and collect fees and charges for public services or specific infrastructure projects. The Company also includes within public finance obligations those obligations backed by the cash flow from leases or other revenues from projects serving substantial public purposes, including utilities, toll roads, health care facilities and government office buildings. The Company also includes within public finance similar obligations issued by territorial and non-U.S. sovereign and sub-sovereign issuers and governmental authorities.


Structured finance obligations insured by the Company are generally issued by special purpose entities, including VIEs, and backed by pools of assets having an ascertainable cash flow or market value or other specialized financial obligations. Some of these VIEs are consolidated as described in Note 9, Consolidated Variable Interest Entities. Unless

otherwise specified, the outstanding par and debt service amounts presented in this note include outstanding exposures on VIEs whether or not they are consolidated. The Company also provides non-financial guaranty insurance and reinsurance on transactions without special purpose entities but with similar risk profiles to its structured finance exposures written in financial guaranty form.

Second-to-pay insured par outstanding represents transactions the Company has insured that are insured directly by another monoline financial guaranty insurer and where the Company's obligation to pay under its insurance of such transactions arises only if both the underlying insured obligation and the primary financial guarantor insurer default. The Company underwrites such transactions based on the underlying insured obligation without regard to the primary insurer. The second-to-pay insured par outstanding as of December 31, 2018 and 2017 was $6.7 billion and $6.6 billion, respectively. The par on second-to-pay exposure where the ratings of the primary insurer and underlying transaction are both BIG and/or not rated is $111 million and $204 million as of December 31, 2018 and December 31, 2017, respectively.

Significant Risk Management Activities

The Portfolio Risk Management Committee, which includes members of senior management and senior creditrisk and surveillance officers, setsestablishes company-wide credit policy for the Company's direct and assumed business. It implements specific risk policiesunderwriting procedures and limits for the Company and allocates underwriting capacity among the Company's subsidiaries. The Portfolio Risk Management Committee is responsible for enterprise risk management establishingfor the Company'soverall company and focuses on measuring and managing credit, market and liquidity risk appetite, credit underwritingfor the overall company. All transactions in new asset classes or new jurisdictions must be approved by this committee. The U.S., U.K., AG Re and AGRO risk management committees conduct an in-depth review of new business,the insured portfolios of the relevant subsidiaries, focusing on varying portions of the portfolio at each meeting. They review and may revise internal ratings assigned to the insured transactions and review sector reports, monthly product line surveillance reports and work-out.compliance reports.
    
All transactions in the insured portfolio are assigned internal credit ratings by the relevant underwriting committee at inception, which credit ratings are updated by the relevant risk management committee based on changes in transaction credit quality. As part of the surveillance process, the Company monitors trends and changes in transaction credit quality, detects any deterioration in credit quality, and recommends such remedial actions as may be necessary or appropriate. All transactions in the insured portfolio are assigned internal credit ratings, which are updated based on changes in transaction credit quality. The Company also develops strategies to enforce its contractual rights and remedies and to mitigate its losses, engage in negotiation discussions with transaction participants and, when necessary, manage the Company's litigation proceedings.

Surveillance Categories
 
The Company segregates its insured portfolio into investment grade and BIG surveillance categories to facilitate the appropriate allocation of resources to monitoring and loss mitigation efforts and to aid in establishing the appropriate cycle for periodic review for each exposure. BIG exposures include all exposures with internal credit ratings below BBB-. The Company’s internal credit ratings are based on internal assessments of the likelihood of default and loss severity in the event of default. Internal credit ratings are expressed on a ratings scale similar to that used by the rating agencies and are generally reflective of an approach similar to that employed by the rating agencies, except that the Company's internal credit ratings focus on future performance rather than lifetime performance.
 
The Company monitors its investment grade credits to determine whether any need to be internally downgraded to BIGinsured portfolio and refreshes its internal credit ratings on individual creditsexposures in quarterly, semi-annual or annual cycles based on the Company’s view of the credit’sexposure’s quality, loss potential, volatility and sector. Ratings on creditsexposures in sectors identified as under the most stress or with the most potential volatility are reviewed every quarter. The Company’squarter, although the Company may also review a rating in response to developments impacting the credit when a ratings on assumed credits are based on the Company’s reviews of low-rated credits or credits in volatile sectors, unless such informationreview is not available, in which case,scheduled. For assumed exposures, the Company may use the ceding company’s credit ratings of transactions where it is impractical for it to assign its own rating. The Company provides surveillance for exposures assumed from SGI, so for those exposures the transactions are used.Company assigns its own rating.
 
CreditsExposures identified as BIG are subjected to further review to determine the probability of a loss. See Note 5, Expected Loss to be Paid, for additional information. Surveillance personnel then assign each BIG transaction to the appropriate BIG surveillance category based upon whether a future loss is expected and whether a claim has been paid. The Company uses a tax-equivalent yield, which reflects long-term trends in interest rates, to calculate the present value of projected payments and recoveries and determine whether a future loss is expected in order to assign the appropriate BIG surveillance category to a transaction. For surveillancefinancial statement measurement purposes, the Company calculates present value using a discount rate of 4% or 5% depending on the insurance subsidiary. (Risk-freeuses risk-free rates, which are used for calculatingdetermined each quarter, to calculate the expected loss for financial statement measurement purposes.)loss.

More extensive monitoring and intervention is employed for all BIG surveillance categories, with internal credit ratings reviewed quarterly. TheFor purposes of determining the appropriate surveillance category, the Company expects “future losses” on a transaction when the Company believes there is at least a 50% chance that, on a present value basis, it will pay more claims on that transaction in the future of that transaction than it will have reimbursed. The three BIG categories are:
 
BIG Category 1: Below-investment-grade transactions showing sufficient deterioration to make future losses possible, but for which none are currently expected.
 
BIG Category 2: Below-investment-grade transactions for which future losses are expected but for which no claims (other than liquidity claims, which are claims that the Company expects to be reimbursed within one year) have yet been paid.
 
BIG Category 3: Below-investment-grade transactions for which future losses are expected and on which claims (other than liquidity claims) have been paid.


Components of Outstanding Exposure

Unless otherwise noted, ratings disclosed herein on the Company's insured portfolio reflect its internal ratings. The Company classifies those portions of risks benefiting from reimbursement obligations collateralized by eligible assets held in trust in acceptable reimbursement structures as the higher of 'AA' or their current internal rating.

Financial Guaranty Exposure

The Company purchases securities that it has insured, and for which it has expected losses to be paid, in order to mitigate the economic effect of insured losses (loss mitigation securities). The Company excludes amounts attributable to loss mitigation securities (unless otherwise indicated) from par and debt service outstanding, which amounts are included in the investment portfolio, because it manages such securities as investments and not insurance exposure. As of December 31, 20162018 and December 31, 2015,2017, the Company excluded $2.1$1.9 billion and $1.5$2.0 billion, respectively, of net par as a result ofattributable to loss mitigation securities, and other loss mitigation strategies including loss mitigation securities held in the investment portfolio, which(which are primarily BIG. mostly BIG).

Exposure to Puerto Rico
    
The Company hashad insured exposure to general obligation bonds of the Commonwealth of Puerto Rico (Puerto Rico or the Commonwealth) and various obligations of its related authorities and public corporations aggregating $4.8 billion net par as of December 31, 2016,2018, all of which arewas rated BIG. Puerto Rico has experienced significant general fund budget deficits in recent years and a challenging economic environment.environment since at least the financial crisis. Beginning on January 1, 2016, a number of Puerto Rico creditsexposures have defaulted on bond payments, and the Company has now paid claims on severalall of its Puerto Rico credits as shown in the table "Puertoexposures except for Puerto Rico Net Par Outstanding" below.Aqueduct and Sewer Authority (PRASA), Municipal Finance Agency (MFA) and University of Puerto Rico (U of PR).

On November 30, 2015 and December 8, 2015, Governor García Padillathe former governor of Puerto Rico (the Former(Former Governor) issued executive orders (Clawback Orders) directing the Puerto Rico Department of Treasury and the Puerto Rico Tourism Company to retain or transfer"claw back" certain taxes pledged to secure the payment of bonds issued by the Puerto Rico Highways and Transportation Authority (PRHTA), Puerto Rico Infrastructure Financing Authority (PRIFA), and Puerto Rico Convention Center District

Center District Authority (PRCCDA). On January 7, 2016, the Company sued various Puerto Rico governmental officials in the United States District Court, District of Puerto Rico, asserting that this attempt to “claw back” pledged taxes is unconstitutional, and demanding declaratory and injunctive relief. The Puerto Rico creditsexposures insured by the Company subject to the Clawback Ordersclawback are shown in the table “Puerto Rico Net Par Outstanding” below.Outstanding."

On April 6,June 30, 2016, the Former Governor signed into law the Puerto Rico Emergency Moratorium & Financial Rehabilitation Act (the Moratorium Act). The Moratorium Act purportedly empowers the governor to declare, entity by entity, states of emergencies and moratoriums on debt service payments on obligations of the Commonwealth and its related authorities and public corporations, as well as instituting a stay against related litigation, among other things. The Former Governor used the authority of the Moratorium Act to take a number of actions related to issuers of obligations the Company insures. National Public Finance Guarantee Corporation (National) (another financial guarantor), holders of the Commonwealth general obligation bonds and certain Puerto Rico residents (the National Plaintiffs) have filed suits to invalidate the Moratorium Act, and after the passage of the Puerto Rico Oversight, Management, and Economic Stability Act (PROMESA), the National Plaintiffs sought a relief from the stay of litigation imposed by PROMESA to pursue the action. On July 21, 2016, the Company filed a motion and form of complaint in the U.S. District Court for the District of Puerto Rico seeking relief from the stay of litigation imposed by PROMESA to seek a declaration that the Moratorium Act is preempted by Federal bankruptcy law. In November 2016 that court denied both the Company's and the National Plaintiffs' motions for relief from stay in the respective actions. The PROMESA stay expires on May 1, 2017.

On June 30, 2016, PROMESA was signed into law by the President of the United States. PROMESA establishesestablished a seven-member federal financial oversight board (Oversight Board) with authority to require that balanced budgets and fiscal plans be adopted and implemented by Puerto Rico. On February 15, 2019, the United States Court of Appeals for the First Circuit (First Circuit) held that members of the Oversight Board were not appointed in compliance with the appointments clause of the U.S. Constitution, but declined to dismiss the Title III petitions previously filed by the Oversight Board and delayed the effectiveness of its ruling for 90 days so as to allow the President of the United States and the U.S. Senate to validate the currently defective appointments or reconstitute the Oversight Board in accordance with the appointments clause. See "Puerto Rico Recovery Litigation" below.

PROMESA provides a legal framework under which the debt of the Commonwealth and its related authorities and public corporations may be voluntarily restructured, and grants the Oversight Board the sole authority to file restructuring petitions in a federal court to restructure the debt of the Commonwealth and its related authorities and public corporations if voluntary negotiations fail, provided that any such restructuring must be in accordance with an Oversight Board approved fiscal plan that respects the liens and priorities provided under Puerto Rico law. Title III of PROMESA also appearsprovides for a process analogous to preempt at least portions of the Moratorium Act and to stay debt-related litigation, including the Company’s litigation regarding the Clawback Orders. On August 31, 2016, the Presidenta voluntary bankruptcy process under chapter 9 of the United States appointed the seven membersBankruptcy Code (Bankruptcy Code).

Judge Laura Taylor Swain of the Oversight Board.Southern District of New York was selected by Chief Justice John Roberts of the United States Supreme Court to preside over any legal proceedings under PROMESA.

On September 20, 2017, Hurricane Maria made landfall in Puerto Rico as a Category 4 hurricane on the Saffir-Simpson scale, causing loss of life and widespread devastation in the Commonwealth. Damage to the Commonwealth’s infrastructure, including the power grid, water system and transportation system, was extensive, and rebuilding and economic recovery are expected to take years.

The Oversight Board has begun meeting and has hired Ramón Ruiz-Comas as interim executive director. On January 2, 2017, Ricardo Antonio Rosselló Nevares (the Governor) took office, replacingcertified a number of fiscal plans (in some instances certifying revisions of previously certified plans) for the Former Governor. On January 29, 2017, the Governor signed theCommonwealth, PRHTA, Puerto Rico EmergencyElectric Power Authority (PREPA) and Fiscal Responsibility Act (Emergency Act)PRASA. The Company does not believe the certified fiscal plans for the Commonwealth, PRHTA, PREPA or PRASA comply with certain mandatory requirements of PROMESA.

The Company believes that among other things, repeals portionsa number of the Moratorium Act, defines an emergency period until May 1, 2017, continues diversion of collateral away from bondsactions taken by the Commonwealth, the Oversight Board and others with respect to obligations the Company insures are illegal or unconstitutional or both, and defineshas taken legal action, and may take additional legal action in the powersfuture, to enforce its rights with respect to these matters. See “Puerto Rico Recovery Litigation” below.

The Company also participates in mediation and duties of the Fiscal Agency and Financial Advisory Authority (FAFAA). negotiations relating to its Puerto Rico exposure.

The final shape,form and timing and validity of responses to Puerto Rico’s financial distress and the devastation of Hurricane Maria eventually enactedtaken by the federal government or implemented under the auspices of PROMESA and the Oversight Board or otherwise, and the final impact, after resolution of legal challenges, of any such responses on obligations insured by the Company, isare uncertain.

The Company groups its Puerto Rico exposure into three categories:

Constitutionally Guaranteed. The Company includes in this category public debt benefiting from Article VI of the Constitution of the Commonwealth, which expressly provides that interest and principal payments on the public debt are to be paid before other disbursements are made.

Public Corporations – Certain Revenues Potentially Subject to Clawback. The Company includes in this category the debt of public corporations for which applicable law permits the Commonwealth to claw back, subject to certain conditions and for the payment of public debt, at least a portion of the revenues supporting the bonds the Company insures. As a Constitutionalconstitutional condition to clawback, available Commonwealth revenues for any fiscal year must be insufficient to pay Commonwealth debt service before the payment of any appropriations for that year.  The Company believes that this condition has not been satisfied to date, and accordingly that the Commonwealth has not to date been entitled to clawbackclaw back revenues supporting debt insured by the Company.As noted above, the Company sued various Puerto Rico governmental officials in the United States District Court, District of Puerto Rico asserting that Puerto Rico's recent attempt to claw back pledged taxes is unconstitutional, and demanding declaratory and injunctive relief.


Other Public Corporations. The Company includes in this category the debt of public corporations that are supported by revenues it does not believe are subject to clawback.


Constitutionally Guaranteed

General Obligation. As of December 31, 2016,2018, the Company had $1,476$1,340 million insured net par outstanding of the general obligations of Puerto Rico, which are supported by the good faith, credit and taxing power of the Commonwealth. On July 1, 2016, despiteDespite the requirements of Article VI of its Constitution, but pursuant to an executive order issued by the Former Governor under the Moratorium Act, the Commonwealth defaulted on most of the debt service payment due that day,on July 1, 2016, and the Company made its firsthas been making claim payments on these bonds since that date. The Oversight Board has filed a petition under Title III of PROMESA with respect to the Commonwealth.

On October 23, 2018, the Oversight Board certified a revised fiscal plan for the Commonwealth. The revised certified Commonwealth fiscal plan indicates an expected primary budget surplus, if fiscal plan reforms are enacted, of $17.0 billion that would be available for debt service over the six-year forecast period ending 2023. The Company believes the available surplus set forth in the Oversight Board's revised certified fiscal plan (which assumes certain fiscal reforms are implemented by the Commonwealth) should be sufficient to cover contractual debt service of Commonwealth general obligation issuances and has continuedof authorities and public corporations directly implicated by the Commonwealth’s general fund during the forecast period. However, the revised certified Commonwealth fiscal plan indicates a net primary budget deficit for the period from 2023 through 2058, and there can be no assurance that the fiscal reforms will be enacted or, if they are, that the forecasted primary budget surplus will occur or, if it does, that such funds will be used to make claim paymentscover contractual debt service.

On January 14, 2019, the Oversight Board and certain other parties filed an objection in the United States District Court for the District of Puerto Rico (Federal District for Puerto Rico) seeking an order, among other things, disallowing claims based on the Commonwealth’s general obligation bonds issued on or after March 2012, contending that these bonds.bonds were issued in violation of the Commonwealth’s debt service limits. As of December 31, 2018, $369 million of the Company’s insured net par outstanding of the general obligation bonds of Puerto Rico were issued on or after March 2012.

Puerto Rico Public Buildings Authority (PBA). As of December 31, 2016,2018, the Company had $169$142 million insured net par outstanding of PBA bonds, which are supported by a pledge of the rents due under leases of government facilities to departments, agencies, instrumentalities and municipalities of the Commonwealth, and that benefit from a Commonwealth guaranty supported by a pledge of the Commonwealth’s good faith, credit and taxing power. On July 1, 2016, despiteDespite the requirements of Article VI of its Constitution, but pursuant to an executive order issued by the Former Governor under the Moratorium Act, the PBA defaulted on most of the debt service payment due that day,on July 1, 2016, and the Company made its firsthas been making claim payments on these bonds since then.

On December 21, 2018, the Oversight Board and certain other parties filed an adversary complaint in the Federal Court for Puerto Rico seeking a declaratory judgment that, among other things, the leases to public entities entered into by the PBA are not “true leases” for purposes of Section 365(d)(3) of the Bankruptcy Code and so the Commonwealth has continuedno obligation to make claim payments on these bonds.

payment to the PBA under such leases. On January 28, 2019, AGM and AGC moved to intervene in that action.
Public Corporations - Certain Revenues Potentially Subject to Clawback

PRHTA. As of December 31, 2016,2018, the Company had $918$844 million insured net par outstanding of PRHTA (Transportation(transportation revenue) bonds and $350$475 million insured net par outstanding of PRHTA (Highways(highways revenue) bonds. The transportation revenue bonds are secured by a subordinate gross pledge oflien on gasoline and gas oil and diesel oil taxes, motor vehicle license fees and certain tolls, plus a first lien on up to $120 million annually of taxes on crude oil, unfinished oil and derivative products. The highways revenue bonds are secured by a gross pledge oflien on gasoline and gas oil and diesel oil taxes, motor vehicle license fees and certain tolls. The Clawback Orders cover Commonwealth-derivednon-toll revenues consisting of excise taxes and fees collected by the Commonwealth on behalf of PRHTA and its bondholders that are statutorily allocated to PRHTA and its bondholders are potentially subject to clawback. Despite the presence of funds in relevant debt service reserve accounts that the Company believes should have been employed to fund debt service, PRHTA defaulted on the full July 1, 2017 insured debt service payment, and the Company has been making claim payments on these bonds since that date. The Oversight Board has filed a petition under Title III of PROMESA with respect to PRHTA.

On June 29, 2018, the Oversight Board certified a revised fiscal plan for PRHTA. The Company believes that such sources represented a substantial majority of PRHTA’s revenues in 2015. Therevised certified PRHTA bonds are subjectfiscal plan projects very limited capacity to executive orders issued pursuant to the Moratorium Act. As noted above, the Company filed a motion and form of complaint in the U.S. District Court for the District of Puerto Rico seeking relief from the PROMESA stay to seek a declaration that the Moratorium Act is preempted by Federal bankruptcy law and that certain gubernatorial executive orders diverting PRHTA pledged toll revenues (which are not subject to the Clawback Orders) are preempted by PROMESA and violate the U.S. Constitution, and also seeking damages and injunctive relief. That motion was denied on November 2, 2016, on procedural grounds. The PROMESA stay expires on May 1, 2017. There were sufficient funds in the PRHTA bond accounts to make the July 1, 2016 and January 1, 2017 PRHTApay debt service payments guaranteed byover the Company on a primary basis, and those payments were made in full.six-year forecast period.

On December 24, 2015, AGM and AGC entered into a Restructuring Support Agreement (RSA)(PREPA RSA) with PREPA, an ad hoc group of uninsured bondholders and a group of fuel-line lenders that, would, subject to certain conditions, resultwould have resulted in, among other things, modernization of the utility and a restructuring of current debt. Upon finalization
The Oversight Board did not certify the PREPA RSA under Title VI of PROMESA as the contemplated restructuring transaction, insuredCompany believes was required by PROMESA, but rather, on July 2, 2017, commenced proceedings for PREPA revenue bonds (with no reduction to par or stated interest rate or extensionunder Title III of maturity) will be supported by securitization bonds issued by a special purpose corporation and secured by a transition charge assessed on ratepayers. To facilitate the securitization transaction and in exchange for a market premium, Assured Guaranty will issue surety insurance policies in an aggregate amount not expected to exceed $113 million ($14 million for AGC and $99 million for AGM) to support a portion of the reserve fund for the securitization bonds. Certain of the creditors also agreed, subject to certain conditions, to participate in a bridge financing, which was closed in two tranches on May 19, 2016 and June 22, 2016.

AGM's and AGC's share of the bridge financing was approximately $15 million ($2 million for AGC and $13 million for AGM). Legislation meeting the requirements of the RSA was enacted on February 16, 2016, and a transition charge to be paid by PREPA rate payers for debt service on the securitization bonds as contemplated by the RSA was approved by the Puerto Rico Energy Commission on June 20, 2016. The closing of the restructuring transaction and the issuance of the surety bonds are subject to certain conditions, including execution of acceptable documentation and legal opinions. The RSA has been extended to March 31, 2017.PROMESA.

On July 1, 2016, PREPA made full payment30, 2018, the Oversight Board and the Governor of the $41 million of principal and interest due on PREPA revenue bonds insured by AGM and AGC. That payment was funded in part by AGM’s purchase of $26 millionPuerto Rico announced that they had reached a tentative agreement with a certain group of PREPA bondsbondholders regarding approximately $3 billion, or approximately one-third, of PREPA’s outstanding debt. Bondholders would be able to exchange their debt for new securitization debt maturing in 2020. Upon finalization40 years at 67% of par, plus growth bonds tied to the transactions contemplated byrecovery of Puerto Rico at 10% of par. The Company and certain other creditors of PREPA have not agreed to the RSA, these new PREPA revenue bonds will be supported by securitization bonds contemplated by the RSA. On January 1, 2017, PREPA made full paymentterms of the $18 million of interest due on PREPA revenue bonds insured by AGM and AGC.that tentative agreement.

There can be no assurance thatOn August 1, 2018, the conditions in the RSA will be met or that, if the conditions are met, the RSA's other provisions, including those related to the insured PREPA revenue bonds, will be implemented as currently agreed. In addition, the impact of PROMESA , the Moratorium Act and Emergency Act or any attempt to exercise the power purportedly granted by the Moratorium Act or the Emergency Act on the implementation of the RSA is uncertain. PREPA, during the pendency of the agreements, has suspended deposits into its debt service fund.Oversight Board certified a revised fiscal plan for PREPA.

Puerto Rico Recovery Litigation
The Company believes that a number of the actions taken by the Commonwealth, the Oversight Board and others with respect to obligations it insures are illegal or unconstitutional or both, and has taken legal action, and may take additional legal action in the future, to enforce its rights with respect to these matters.

On January 7, 2016, AGM, AGC and Ambac Assurance Corporation commenced an action for declaratory judgment and injunctive relief in the Federal District Court for Puerto Rico to invalidate the executive orders issued by the Former Governor on November 30, 2015 and December 8, 2015 directing that the Secretary of the Treasury of the Commonwealth of Puerto Rico and the Puerto Rico Tourism Company claw back certain taxes and revenues pledged to secure the payment of bonds issued by the PRHTA, the PRCCDA and the PRIFA. The Commonwealth defendants filed a motion to dismiss the action for lack of subject matter jurisdiction, which the court denied on October 4, 2016. On October 14, 2016, the Commonwealth defendants filed a notice of PROMESA automatic stay. While the PROMESA automatic stay expired on May 1, 2017, on May 17, 2017, the court stayed the action under Title III of PROMESA.

On May 16, 2017, The Bank of New York Mellon, as trustee for the bonds issued by COFINA, filed an adversary complaint for interpleader and declaratory relief with the Federal District Court for Puerto Rico to resolve competing and conflicting demands made by various groups of COFINA bondholders, insurers of certain COFINA Bonds and COFINA, regarding funds held by the trustee for certain COFINA bond debt service payments scheduled to occur on and after June 1, 2017. On May 19, 2017, an order to show cause was entered permitting AGM to intervene in this matter. On February 4, 2019, the Federal District Court for Puerto Rico approved the COFINA Plan of Adjustment described above, and the plan became effective on February 12, 2019. As a result, the interpleader action has been dismissed.

On June 3, 2017, AGC and AGM filed an adversary complaint in the Federal District Court for Puerto Rico seeking (i) a judgment declaring that the application of pledged special revenues to the payment of the PRHTA bonds is not subject to the PROMESA Title III automatic stay and that the Commonwealth has violated the special revenue protections provided to the PRHTA bonds under the Bankruptcy Code; (ii) an injunction enjoining the Commonwealth from taking or causing to be taken any action that would further violate the special revenue protections provided to the PRHTA bonds under the Bankruptcy Code; and (iii) an injunction ordering the Commonwealth to remit the pledged special revenues securing the PRHTA bonds in accordance with the terms of the special revenue provisions set forth in the Bankruptcy Code. On January 30, 2018, the court rendered an opinion dismissing the complaint and holding, among other things, that (x) even though the special revenue provisions of the Bankruptcy Code protect a lien on pledged special revenues, those provisions do not mandate the turnover of pledged special revenues to the payment of bonds and (y) actions to enforce liens on pledged special revenues remain stayed. AGC and AGM are appealing the district court’s decision to the United States Court of Appeals for the First Circuit (First Circuit).

On June 26, 2017, AGM and AGC filed a complaint in the Federal District Court for Puerto Rico seeking (i) a declaratory judgment that the PREPA RSA is a “Preexisting Voluntary Agreement” under Section 104 of PROMESA and the Oversight Board’s failure to certify the PREPA RSA is an unlawful application of Section 601 of PROMESA; (ii) an injunction enjoining the Oversight Board from unlawfully applying Section 601 of PROMESA and ordering it to certify the PREPA RSA; and (iii) a writ of mandamus requiring the Oversight Board to comply with its duties under PROMESA and certify the PREPA RSA. On July 21, 2017, in light of its PREPA Title III petition on July 2, 2017, the Oversight Board filed a notice of stay under PROMESA.


On July 18, 2017, AGM and AGC filed in the Federal District Court for Puerto Rico a motion for relief from the automatic stay in the PREPA Title III bankruptcy proceeding and a form of complaint seeking the appointment of a receiver for PREPA. The court denied the motion on September 14, 2017, but on August 8, 2018, the First Circuit vacated and remanded the court's decision. On October 3, 2018, AGM and AGC, together with other bond insurers, filed a motion with the court to lift the automatic stay to commence an action against PREPA for the appointment of a receiver.

On May 23, 2018, AGM and AGC filed an adversary complaint in the Federal District Court for Puerto Rico seeking a judgment declaring that (i) the Oversight Board lacked authority to develop or approve the new fiscal plan for Puerto Rico which it certified on April 19, 2018 (Revised Fiscal Plan); (ii) the Revised Fiscal Plan and the Fiscal Plan Compliance Law (Compliance Law) enacted by the Commonwealth to implement the original Commonwealth Fiscal Plan violate various sections of PROMESA; (iii) the Revised Fiscal Plan, the Compliance Law and various moratorium laws and executive orders enacted by the Commonwealth to prevent the payment of debt service (a) are unconstitutional and void because they violate the Contracts, Takings and Due Process Clauses of the U.S. Constitution and (b) are preempted by various sections of PROMESA; and (iv) no Title III plan of adjustment based on the Revised Fiscal Plan can be confirmed under PROMESA. On August 13, 2018, the court-appointed magistrate judge granted the Commonwealth's and the Oversight Board's motion to stay this adversary proceeding pending a decision by the First Circuit in an appeal of an unrelated adversary proceeding decision by Ambac Assurance Corporation, which may resolve certain similar issues.

On July 23, 2018, AGC and AGM filed an adversary complaint in the Federal District Court for Puerto Rico seeking a judgment (i) declaring the members of the Oversight Board are officers of the U.S. whose appointments were unlawful under the Appointments Clause of the U.S. Constitution; (ii) declaring void ab initio the unlawful actions taken by the Oversight Board to date, including (x) development of the Commonwealth's Fiscal Plan, (y) development of PRHTA's Fiscal Plan, and (z) filing of the Title III cases on behalf of the Commonwealth and PRHTA; and (iii) enjoining the Oversight Board from taking any further action until the Oversight Board members have been lawfully appointed in conformity with the Appointments Clause of the U.S. Constitution. The Title III court dismissed a similar lawsuit filed by another party in the Commonwealth’s Title III case in July 2018. On August 3, 2018, a stipulated judgment was entered against AGM and AGC at their request based upon the court's July decision in the other Appointments Clause lawsuit and, on the same date, AGM and AGC appealed the stipulated judgment to the First Circuit. On August 15, 2018, the court consolidated, for purposes of briefing and oral argument, AGM and AGC's appeal with the other Appointments Clause lawsuit. The First Circuit consolidated AGM's and AGC's appeal with a third Appointments Clause lawsuit on September 7, 2018 and held a hearing on December 3, 2018. On February 15, 2019, the First Circuit issued its ruling on the appeal and held that members of the Oversight Board were not appointed in compliance with the Appointments Clause of the U.S. Constitution but declined to dismiss the Title III petitions citing the (i) de facto officer doctrine and (ii) negative consequences to the many innocent third parties who relied on the Oversight Board’s actions to date, as well as the further delay which would result from a dismissal of the Title III petitions. The case was remanded back to the Federal District Court for Puerto Rico for the appellants’ requested declaratory relief that the appointment of the board members of the Oversight Board is unconstitutional. The First Circuit delayed the effectiveness of its ruling for 90 days so as to allow the President and the Senate to validate the currently defective appointments or reconstitute the Oversight Board in accordance with the Appointments Clause.

Exposure to the Selected European CountriesU.S. Virgin Islands
As of December 31, 2018, the Company had $496 million insured net par outstanding to the U.S. Virgin Islands and its related authorities (USVI), of which it rated $222 million BIG. The $274 million USVI net par the Company rated investment grade primarily consisted of bonds secured by a lien on matching fund revenues related to excise taxes on products produced in the USVI and exported to the U.S., primarily rum. The $222 million BIG USVI net par consisted of (a) Public Finance Authority bonds secured by a gross receipts tax and the general obligation, full faith and credit pledge of the USVI and (b) bonds of the Virgin Islands Water and Power Authority secured by a net revenue pledge of the electric system.
Hurricane Irma caused significant damage in St. John and St. Thomas, while Hurricane Maria made landfall on St. Croix as a Category 4 hurricane on the Saffir-Simpson scale, causing loss of life and substantial damage to St. Croix’s businesses and infrastructure, including the power grid. The USVI is benefiting from the federal response to the 2017 hurricanes and has made its debt service payments to date.

The European countries where the Company has exposure and believes heightened uncertainties exist are: Hungary, Italy, Portugal, Spain and Turkey (collectively, the Selected European Countries). Non-Financial Guaranty Exposure

The Company added Turkeyalso provides non-financial guaranty insurance and reinsurance on transactions with similar risk profiles to its list of Selected European Countriesstructured finance exposures written in 2016, as a result of the recent political turmoil in the country.

While exposures are shown in U.S. dollars, the obligations are in various currencies, primarily euros.
The life insurance capital relief transactions net exposure is expected to increase to approximately $1.0 billion prior to September 30, 2036.

Sub-sovereign exposure in Selected European Countries includes transactions backed by receivables from, or supported by, sub-sovereigns, which are governmental or government-backed entities other than the ultimate governing body of the country.

(3)
Non-sovereign exposure in Selected European Countries includes debt of regulated utilities, RMBS and diversified payment rights (DPR) securitizations.

When the Company directly insures an obligation, it assigns the obligation to a geographic location or locations based on its view of the geographic location of the risk. The Company may also have direct exposures to the Selected European Countries in business assumed from unaffiliated monoline insurance companies, in which case the Company depends upon geographic information provided by the primary insurer.

The Company's $202 million net insured par exposure in Turkey is to DPR securitizations sponsored by a major Turkish bank. These DPR securitizations were established outside of Turkey and involve payment orders in U.S. dollars, pounds sterling and Euros from persons outside of Turkey to beneficiaries in Turkey who are customers of the sponsoring bank. The sponsoring bank's correspondent banks have agreed to remit all such payments to a trustee-controlled account outside Turkey, where debt service payments for the DPR securitization are given priority over payments to the sponsoring bank.

The Company has excluded from the exposure tables above its indirect economic exposure to the Selected European Countries through policies it provides on pooled corporate and commercial receivables transactions. The Company calculates indirect exposure to a country by multiplying the par amount of a transaction insured by the Company times the percent of the relevant collateral pool reported as having a nexus to the country. On that basis, the Company has calculated exposure of $115 million to Selected European Countries (plus Greece) in transactions with $2.8 billion of net par outstanding. The indirect exposure to credits with a nexus to Greece is $3 million across several highly rated pooled corporate obligations with net par outstanding of $129 million.

5.Expected Loss to be Paid
 
The insured portfolio includes policies accountedManagement compiles and analyzes loss information for under three separate accounting models dependingall exposures on the characteristics of the contract and the Company's control rights. The Company has paid and expects to pay future losses on policies which fall under each of the three accounting models. The following provides a summarized description of the three accounting models prescribed by GAAP with a reference to the notes that describe the accounting policies and required disclosures throughout this report. The three models are: (1) insurance, (2) derivative and (3) VIE consolidation.

Inconsistent basis, in order to effectively evaluate and manage the economics and liquidity of the entire insured portfolio, management compiles and analyzes loss information for all policies on a consistent basis.portfolio. The Company monitors and assigns ratings and calculates expected losses in the same manner for all its exposures regardless of form or differing accounting models.

This note provides information regarding expected claim payments to be made under all contracts in the insured portfolio, regardless of the accounting model. Net expected loss to be paid in the tables below consists of the present value of future: expected claim and LAE payments, expected recoveries in the transaction structures, cessions to reinsurers, and expected recoveries for breaches of representations and warranties (R&W) and other loss mitigation strategies. portfolio.

Expected loss to be paid is important from a liquidity perspective in that it represents the present value of amounts that the Company expects to

pay or recover in future periods regardless of the accounting model. Expected loss to be paid is an important measure used by management to analyze the net economic loss onfor all contracts.

Accounting Policy

Insurance Accounting

For contracts accounted for as financial guaranty insurance, loss and LAE reserve is recorded only to the extent and for the amount that expected losses to be paid, exceed unearned premium reserve. As a result, the Company has expected loss to be paid that have not yet been expensed. Such amounts will be recognized in future periods as deferred premium revenue amortizes into income. Expected loss to be expensed is important because it represents the Company's projection of incurred losses that will be recognized in future periods (excluding accretion of discount). See "Financial Guaranty Insurance Losses" in Note 6, Contracts Accounted for as Insurance.

Derivative Accounting, at Fair Value

For contracts that do not meet the financial guaranty scope exception in the derivative accounting guidance (primarily due to the fact that the insured is not required to be exposed to the insured risk throughout the life of the contract), the Company records such credit derivative contracts at fair value on the consolidated balance sheet with changes in fair value recorded in the consolidated statement of operations. The fair value recorded on the balance sheet represents an exit price in a hypothetical market because the Company does not trade its credit derivative contracts. The fair value is determined using significant Level 3 inputs in an internally developed model while the expected loss to be paid (which represents the net present value of expected cash outflows) uses methodologies and assumptions consistent with financial guaranty insurance expected losses to be paid. See Note 7, Fair Value Measurement and Note 8, Contracts Accounted for as Credit Derivatives.

VIE Consolidation, at Fair Value

For financial guaranty (FG) insurance contracts issued on the debt of variable interest entities over which the Company is deemed to be the primary beneficiary due to its control rights, as defined in GAAP, the Company consolidates the FG VIE. The Company carries the assets and liabilities of the FG VIEs at fair value under the fair value option. Management assesses the expected losses on the insured debt of the consolidated FG VIEs in the same manner as other financial guaranty insurance and credit derivative contracts. See Note 9, Consolidated Variable Interest Entities.
Expected Loss to be Paid

The expected loss to be paid is equal to the present value of expected future cash outflows for claim and LAE payments, net of inflows for expected salvage and subrogation (e.g., future payments by obligors pursuant to restructuring agreements, settlements or litigation judgments, excess spread on the underlying collateral, and expectedother estimated recoveries, including those from restructuring bonds and contractual recoveries for breaches of R&W or other expected recoveries)representations and warranties (R&W)), using current risk-free rates. When the Company becomes entitled to the cash flow from the underlying collateral of an insured credit under salvage and subrogation rights as a result of a claim payment or estimated future claim payment, it reduces the expected loss to be paid on the contract. Net expected loss to be paid is defined as expected loss to be paid, net of amounts ceded to reinsurers.

The Company updates the discount rate each quarter and reflects the effect of such changes in economic loss development. Expected cash outflows and inflows are probability weighted cash flows that reflect the likelihood of all possible outcomes. The Company estimates the expected cash outflows and inflows using management's assumptions about the likelihood of all possible outcomes based on all information available to it. Those assumptions consider the relevant facts and circumstances and are consistent with the information tracked and monitored through the Company's risk-management activities.

Economic Loss Development

Economic The Company updates the discount rates each quarter and reflects the effect of such changes in economic loss development represents the change in netdevelopment. Net expected loss to be paid attributable to the effects of changes in assumptions based on observed market trends, changes in discount rates, accretion of discount and the economic effects of loss mitigation efforts.

Expectedis defined as expected loss to be paid, and economic loss development includenet of amounts ceded to reinsurers.

In circumstances where the effects of loss mitigation strategies such as negotiatedCompany has purchased its own insured obligations that have expected losses, and estimated recoveries for breaches of R&W, and purchases of insured debt obligations. Additionally, in certain cases issuers of insured obligations elected or the Company and an issuer mutually agreed as part of a negotiation to deliver the underlying collateral or insured obligation to the Company.

In circumstances where the Company, has purchased its own insured obligations that have expected losses, expected loss to be paid is reduced by the proportionate share of the insured obligation that is held in the investment portfolio. The difference between the purchase price of the obligation and the fair value excluding the value of the Company's insurance is treated as a paid loss. Assets that are purchased by the Company are recorded in the investment portfolio, at fair value excluding the value of the Company's insurance. See Note 10, Investments and Cash and Note 7, Fair Value Measurement.

Economic loss development represents the change in net expected loss to be paid attributable to the effects of changes in assumptions based on observed market trends, changes in discount rates, accretion of discount and the economic effects of loss mitigation efforts.

The insured portfolio includes policies accounted for under three separate accounting models depending on the characteristics of the contract and the Company's control rights. The three models are: (1) insurance as described in "Financial Guaranty Insurance Losses" in Note 6, Contracts Accounted for as Insurance, (2) derivative as described in Note 7, Fair Value Measurement and Note 8, Contracts Accounted for as Credit Derivatives, and (3) VIE consolidation as described in Note 9, Variable Interest Entities. The Company has paid and expects to pay future losses (net of recoveries) on policies which fall under each of the three accounting models.

Loss Estimation Process
 
The Company’s loss reserve committees estimate expected loss to be paid for all contracts by reviewing analyses that consider various scenarios with corresponding probabilities assigned to them. Depending upon the nature of the risk, the Company’s view of the potential size of any loss and the information available to the Company, that analysis may be based upon individually developed cash flow models, internal credit rating assessments, and sector-driven loss severity assumptions and/or judgmental assessments. In the case of its assumed business, the Company may conduct its own analysis as just described or, depending on the Company’s view of the potential size of any loss and the information available to the Company, the Company may use loss estimates provided by ceding insurers. The Company monitors the performance of its transactions with expected losses and each quarter the Company’s loss reserve committees review and refresh their loss projection assumptions, and scenarios and the probabilities they assign to those scenarios based on actual developments during the quarter and their view of future performance.

The financial guaranties issued by the Company insure the credit performance of the guaranteed obligations over an extended period of time, in some cases over 30 years, and in most circumstances the Company has no right to cancel such financial guaranties. As a result, the Company's estimate of ultimate lossesloss on a policy is subject to significant uncertainty over the life of the insured transaction. Credit performance can be adversely affected by economic, fiscal and financial market variability over the long life of most contracts.

The determination of expected loss to be paid is an inherently subjective process involving numerous estimates, assumptions and judgments by management, using both internal and external data sources with regard to frequency, severity of loss, economic projections, governmental actions, negotiations and other factors that affect credit performance. These estimates, assumptions and judgments, and the factors on which they are based, may change materially over a reporting period, and as a result the Company’s loss estimates may change materially over that same period.

Changes in the Company’s loss estimates for structured finance transactions generally will be influenced by factors impacting the performance of the assets supporting those transactions. For example, changes over a reporting period in the Company’s loss estimates for its RMBS transactions may be influenced by such factors as the level and timing of loan defaults experienced; changes in housing prices; results from the Company's loss mitigation activities; and other variables.

Similarly, changes over a reporting period in the Company’s loss estimates for municipal obligations supported by specified revenue streams, such as revenue bonds issued by toll road authorities, municipal utilities or airport authorities, generally will be influenced by factors impacting their revenue levels, such as changes in demand; changing demographics; and other economic factors, especially if the obligations do not benefit from financial support from other tax revenues or governmental authorities. Changes over a reporting period in the Company’s loss estimates for its tax-supported public finance transactions generally will be influenced by factors impacting the public issuer’s ability and willingness to pay, such as changes in the economy and population of the relevant area; changes in the issuer’s ability or willingness to raise taxes, decrease spending or receive federal assistance; new legislation; rating agency downgradesactions that reduceaffect the issuer’s ability to refinance maturing obligations or issue new debt at a reasonable cost; changes in the priority or amount of pensions and other obligations owed to workers; developments in restructuring or settlement negotiations; and other political and economic factors. Changes in loss estimates may also be affected by the Company's loss mitigation efforts.

Changes in the Company’s loss estimates for structured finance transactions generally will be influenced by factors impacting the performance of the assets supporting those transactions. For example, changes over a reporting period in the Company’s loss estimates for its RMBS transactions may be influenced by factors such as the level and timing of loan defaults experienced; changes in housing prices; results from the Company's loss mitigation activities; and other variables.

The Company does not use traditional actuarial approaches to determine its estimates of expected losses. Actual losses will ultimately depend on future events or transaction performance and may be influenced by many interrelated factors that are difficult to predict. As a result, the Company's current projections of probable and estimable losses may be subject to considerable volatility and may not reflect the Company's ultimate claims paid.

In some instances, the terms of the Company's policy gives it the option to pay principal losses that have been recognized in the transaction but which it is not yet required to pay, thereby reducing the amount of guaranteed interest due in the future. The Company has sometimes exercised this option, which uses cash but reduces projected future losses.


The following tables present a roll forward of the present value of net expected loss to be paid for all contracts, whether accounted for as insurance, credit derivatives or FG VIEs, by sector, after the benefit for expected recoveries for breaches of R&W and other expected recoveries.contracts. The Company used risk-free rates for U.S. dollar denominated obligations that ranged from 0.0%0.00% to 3.23%3.06% with a weighted average of 2.73%2.74% as of December 31, 20162018 and 0.0%from 0.00% to 3.25%2.78% with a weighted average of 2.36%2.38% as of December 31, 2015.2017. Expected losses to be paid for transactions denominated in currencies other than the U.S. dollar represented approximately 2.7% and 3.7% of the total as of December 31, 2018 and December 31, 2017, respectively.

The Company’s agreements with R&W providers generally provide that, as the Company makes claim payments, the R&W providers reimburse it for those claims; if the Company later receives reimbursement through the transaction (for example, from excess spread), the Company repays the R&W providers. See the section “Breaches of Representations and Warranties” for information about the R&W agreements. When the Company projects receiving more reimbursements in the future than it projects paying in claims on transactions covered by R&W settlement agreements, the Company will have a net R&W payable.

Selected U.S. Public Finance Transactions
    
The Company insuresinsured general obligation bonds of the Commonwealth of Puerto Rico and various obligations of its related authorities and public corporations aggregating $4.8 billion net par as of December 31, 2016,2018, all of which arewas BIG. For additional information regarding the Company's exposure to general obligations of Commonwealth of Puerto Rico and various obligations of its related authorities and public corporations, please refer toexposure, see "Exposure to Puerto Rico" in Note 4, Outstanding Exposure.


As of December 31, 2018, the Company had insured $326 million net par outstanding of general obligation bonds issued by the City of Hartford, Connecticut, most of which was rated BIG at December 31, 2017. In the first quarter of 2018, the State of Connecticut entered into a contract assistance agreement with the City of Hartford under which the state pays the debt service costs of the City’s general obligation bonds, including those insured by the Company. As a result, the Company reduced the corresponding expected losses as of March 31, 2018 and upgraded this exposure to investment grade.
The Company had approximately $18 million of net par exposure as of December 31, 2018 to bonds issued by Parkway East Public Improvement District (District), which is located in Madison County, Mississippi (the County). The bonds, which are rated BIG, are payable from special assessments on properties within the District, as well as amounts paid under a contribution agreement with the County in which the County covenants that it will provide funds in the event special assessments are not sufficient to make a debt service payment. The special assessments have not been sufficient to pay debt service in full. In earlier years, the County provided funding to cover the balance of the debt service requirement, but subsequently claimed the District’s failure to reimburse it within the two years stipulated in the contribution agreement means that the County is not required to provide funding until it is reimbursed. See “Recovery Litigation” at the end of this note for the settlement agreement reached between the County, the District and AGC with respect to the County's obligations.

On February 25, 2015, a plan of adjustment resolving the bankruptcy filing of the City of Stockton, California under chapter 9 of the U.S. Bankruptcy Code became effective. As of December 31, 2016,2018, the Company’s net par subject to the plan consistsconsisted of $113$110 million of pension obligation bonds. As part of the plan settlement,of adjustment, the City will repay any claims paid on the pension obligation bonds from certain fixed payments and certain variable payments contingent on the City's revenue growth. 

The Company projects that its total net expected loss across its troubled U.S. public finance creditsexposures as of December 31, 2016,2018, including those mentioned above, which incorporated the likelihood of the various outcomes, willwould be $871$832 million,

compared with a net expected loss of $771$1,157 million as of December 31, 2015. On July 1, 2016, the CIFG Acquisition added $40 million in2017. The total net economic losses to be paidexpected loss for troubled U.S. public finance credits. Economicexposures is net of a credit for estimated future recoveries of claims already paid. At December 31, 2018, that credit was $586 million, compared with $385 million at December 31, 2017. The economic loss development in 20162018 was $276$70 million, which was primarily attributable to Puerto Rico exposures.exposures, partially offset by a benefit related to the Company's exposure to the City of Hartford.

Certain Selected European Country Sub-SovereignNon - U.S. Public Finance Transactions

The Company insures and reinsures creditstransactions with sub-sovereign exposure to various Spanish and Portuguese issuers where a Spanish and Portuguese sovereign default may cause the sub-sovereigns also to default. The Company's exposure net of reinsurance to these Spanish and Portuguese creditsexposures is $342$432 million and $76$71 million, respectively. The Company rates mostall of these issuersexposures BIG due to the financial condition of Spain and Portugal and their dependence on the sovereign.

The Company's HungaryCompany also has exposure is to infrastructure bonds dependent on payments from Hungarian governmental entities. The Company's exposure, net of reinsurance, to these Hungarian creditstransactions is $236$177 million, all of which iswas rated BIG.
The Company estimatedalso insures an obligation backed by the availability and toll revenues of a major arterial road into a city in the U.K. with $198 million of net par outstanding as of December 31, 2018. This transaction has been underperforming due to higher costs compared with expectations at underwriting, and is now rated BIG. However, traffic has been increasing, and in 2018, the Company changed its traffic assumptions for this road, resulting in a benefit.

These transactions, together with other non-U.S. public finance insured obligations, had expected lossesloss to be paid of $29$32 million related to these Spanish, Portuguese and Hungarian credits.as of December 31, 2018, compared with $46 million as of December 31, 2017. The economic benefit of approximately $7$14 million during 20162018 was primarily relatedmainly attributable to the U.K. arterial road and changes in the exchange rate between the euro and U.S. Dollar.certain probability of default assumptions.

Approach to Projecting Losses in U.S. RMBS Loss Projections

The Company projects losses on its insured U.S. RMBS on a transaction-by-transaction basis by projecting the performance of the underlying pool of mortgages over time and then applying the structural features (i.e., payment priorities and tranching) of the RMBS and any expected R&W agreementsrecoveries/payables to the projected performance of the collateral over time. The resulting projected claim payments or reimbursements are then discounted using risk-free rates.
 

The further behind a mortgage borrower falls in making payments, the more likely it is that he or she will default. The rate at which borrowers from a particular delinquency category (number of monthly payments behind) eventually default is referred to as the “liquidation rate.” The Company derives its liquidation rate assumptions from observed roll rates, which are the rates at which loans progress from one delinquency category to the next and eventually to default and liquidation. The Company applies liquidation rates to the mortgage loan collateral in each delinquency category and makes certain timing assumptions to project near-term mortgage collateral defaults from loans that are currently delinquent.
 
Mortgage borrowers that are not more than one payment behind (generally considered performing borrowers) have demonstrated an ability and willingness to pay throughoutthrough the recession and mortgage crisis, and as a result are viewed as less likely to default than delinquent borrowers. Performing borrowers that eventually default will also need to progress through delinquency categories before any defaults occur. The Company projects how many of the currently performing loans will default and when they will default, by first converting the projected near term defaults of delinquent borrowers derived from liquidation rates into a vector of conditional default rates (CDR), then projecting how the CDR will develop over time. Loans that are defaulted pursuant to the CDR after the near-term liquidation of currently delinquent loans represent defaults of currently performing loans and projected re-performing loans. A CDR is the outstanding principal amount of defaulted loans liquidated in the current month divided by the remaining outstanding amount of the whole pool of loans (or “collateral pool balance”). The collateral pool balance decreases over time as a result of scheduled principal payments, partial and whole principal prepayments, and defaults.
 
In order to derive collateral pool losses from the collateral pool defaults it has projected, the Company applies a loss severity. The loss severity is the amount of loss the transaction experiences on a defaulted loan after the application of net proceeds from the disposal of the underlying property. The Company projects loss severities by sector and vintage based on its experience to date. The Company continues to update its evaluation of these loss severities as new information becomes available.
 
The Company hashad been enforcing claims for breaches of R&W regarding the characteristics of the loans included in the collateral pools. The Company calculates a credit for R&W recoveries and payables to include in its cash flow projections. Where the Company has an agreement with an R&W provider (such asprojections based on its agreements with BankR&W providers. As of America and UBS, which are described in more detail under "Breaches of Representations and Warranties" below), that credit is based on the agreement. WhereDecember 31, 2018, the Company does not have an agreementhad a net R&W receivable of $5 million from R&W counterparties, compared with thea net R&W provider but the Company believes thereceivable of $117 million as of December 31, 2017. The decrease was primarily due to cash received in 2018 from a favorable settlement of R&W provider to be economically viable, the Company estimates what portion of its past and projected future claims it believes will be reimbursed by that provider.litigation reached in late December 2017.

The Company projects the overall future cash flow from a collateral pool by adjusting the payment stream from the principal and interest contractually due on the underlying mortgages for the collateral losses it projects as described above; assumed voluntary prepayments; and servicer advances. The Company then applies an individual model of the structure of the transaction to the projected future cash flow from that transaction’s collateral pool to project the Company’s future claims and

claim reimbursements for that individual transaction. Finally, the projected claims and reimbursements are discounted using risk-free rates. The Company runs several sets of assumptions regarding mortgage collateral performance, or scenarios, and probability weights them.

The Company's RMBS loss projection methodology assumes that the housing and mortgage markets will continue improving. Each period the Company makes a judgment as to whether to change the assumptions it uses to make RMBS loss projections based on its observation during the period of the performance of its insured transactions (including early stage delinquencies, late stage delinquencies and loss severity) as well as the residential property market and economy in general, and, to the extent it observes changes, it makes a judgment as to whether those changes are normal fluctuations or part of a trend.
Year-End 2016 Compared to Year-End 2015 U.S. RMBS Loss Projections
Based on its observation during the period of the performance of its insured transactions (including early stage delinquencies, late stage delinquencies and loss severity) as well as the residential property market and economy in general, the Company chose to use the same general The assumptions to project RMBS losses as of December 31, 2016 as it used as of December 31, 2015, except it (1) increased severities for specific vintages of Alt-A first lien, Option ARM and subprime transactions, (2) decreased liquidation rates for specific non-performing categories of subprime transactions and Option ARM and (3) increased liquidation rates for specific non-performing categories of second lien transactions. In 2016 the economic benefit was $68 million for first lien U.S. RMBS and $23 million for second lien U.S. RMBS.

Year-End 2015 Compared to Year-End 2014 U.S. RMBS Loss Projections

Based on its observation during the period of the performance of its insured transactions (including early stage delinquencies, late stage delinquencies and loss severity) as well as the residential property market and economy in general, the Company chose to use the same general assumptions to project RMBS losses as of December 31, 2015 as it used as of December 31, 2014, except that for its first lien RMBS loss projections for 2015, it shortened by twelve months the period it is projecting it will take in the base case to reach the final CDR as compared with December 31, 2014. The methodology and revised assumptions the Company used to project first lien RMBS losses and the scenarios it employed are described in more detail below under " - U.S. First Lien RMBS Loss Projections: Alt A First Lien, Option ARM, Subprime and Prime", and the methodology and assumptions the Company uses to project second lien RMBS losses andare shown in the scenarios it employs are described in more detail below under " - U.S. Second Lien RMBS Loss Projections."

U.S. First Lien RMBS Loss Projections: Alt-A First Lien, Option ARM, Subprime and Prime
The majority of projected losses in first lien RMBS transactions are expected to come from non-performing mortgage loans (those that are or in the past twelve months have been two or more payments behind, have been modified, are in foreclosure, or have been foreclosed upon). Changes in the amount of non-performing loans from the amount projected in the previous period are one of the primary drivers of loss development in this portfolio. In order to determine the number of defaults resulting from these delinquent and foreclosed loans, the Company applies a liquidation rate assumption to loans in each of various non-performing categories. The Company arrived at its liquidation rates based on data purchased from a third party provider and assumptions about how delays in the foreclosure process and loan modifications may ultimately affect the rate at which loans are liquidated. Each quarter the Company reviews the most recent twelve months of this data and (if necessary) adjusts its liquidation rates based on its observations. The following table shows liquidation assumptions for various non-performing categories.

While the Company uses liquidation rates as described above to project defaults of non-performing loans (including current loans modified or delinquent within the last 12 months), it projects defaults on presently current loans by applying a CDR trend. The start of that CDR trend is based on the defaults the Company projects will emerge from currently nonperforming, recently nonperforming and modified loans. The total amount of expected defaults from the non-performing loans is translated into a constant CDR (i.e., the CDR plateau), which, if applied for each of the next 36 months, would be sufficient to produce approximately the amount of defaults that were calculated to emerge from the various delinquency categories. The CDR thus calculated individually on the delinquent collateral pool for each RMBS is then used as the starting point for the CDR curve used to project defaults of the presently performing loans.
 
In the most heavily weighted scenario (the base case,case), after the initial 36-month CDR plateau period, each transaction’s CDR is projected to improve over 12 months to an intermediate CDR (calculated as 20% of its CDR plateau); that intermediate CDR is held constant for 36 months and then trails off in steps to a final CDR of 5% of the CDR plateau. In the base case, the Company assumes the final CDR will be reached 6.54.5 years after the initial 36-month CDR plateau period. Under the Company’s methodology, defaults projected to occur in the first 36 months represent defaults that can be attributed to loans that were modified or delinquent in the last 12 months or that are currently delinquent or in foreclosure, while the defaults projected to occur using the projected CDR trend after the first 36 month period represent defaults attributable to borrowers that are currently performing or are projected to reperform.
     

Another important driver of loss projections is loss severity, which is the amount of loss the transaction incurs on a loan after the application of net proceeds from the disposal of the underlying property. Loss severities experienced in first lien transactions havehad reached historically high levels, and the Company is assuming in the base case that these highthe still elevated levels generally will continue for another 18 months. The Company determines its initial loss severity based on actual recent experience. As a result,Each quarter the Company updatedreviews available data and (if necessary) adjusts its severities for specific asset classes and vintages based on observed data, as shown in the tables below.its observations. The Company then assumes that loss severities begin returning to levels consistent with underwriting assumptions beginning after the initial 18 month period, declining to 40% in the base case over 2.5 years.
 

The following table shows the range as well as the average, weighted by outstanding net insured par, for key assumptions used in the calculation of expected loss to be paid for individual transactions for direct vintage 2004 - 2008 first lien U.S. RMBS.

(1)Represents variables for most heavily weighted scenario (the “base case”).

The rate at which the principal amount of loans is voluntarily prepaid may impact both the amount of losses projected (since that amount is a function of the CDR, the loss severity and the loan balance over time) as well as the amount of excess spread (the amount by which the interest paid by the borrowers on the underlying loan exceeds the amount of interest owed on the insured obligations). The assumption for the voluntary conditional prepayment rate (CPR) follows a similar pattern to that of the CDR. The current level of voluntary prepayments is assumed to continue for the plateau period before gradually increasing over 12 months to the final CPR, which is assumed to be 15% in the base case. For transactions where the initial CPR is higher than the final CPR, the initial CPR is held constant and the final CPR is not used. These CPR assumptions are the same as those the Company used for December 31, 2015.2017.
 
In estimating expected losses, the Company modeled and probability weighted sensitivities for first lien transactions by varying its assumptions of how fast a recovery is expected to occur. One of the variables used to model sensitivities was how

quickly the CDR returned to its modeled equilibrium, which was defined as 5% of the initial CDR. The Company also stressed CPR and the speed of recovery of loss severity rates. The Company probability weighted a total of five scenarios as of December 31, 2016.2018 and December 31, 2017.

Total expected loss to be paid on all first lien U.S. RMBS was $243 million and $123 million as of December 31, 2018 and December 31, 2017, respectively. The reinsurance of the SGI portfolio added $113 million of net expected loss to first lien U.S. RMBS on June 1, 2018. The Company used a similar approach to establish its pessimistic and optimistic scenarios as of December 31, 20162018 as it used as of December 31, 2015,2017, increasing and decreasing the periods of stress from those used in the base case.


In the Company's most stressful scenario where loss severities were assumed to rise and then recover over nine years and the initial ramp-down of the CDR was assumed to occur over 15 months, and other assumptions were the same as the other stress scenario, expected loss to be paid would increase from current projections by approximately $27$54 million for Alt-Aall first liens, $8 million for Option ARM, $46 million for subprime and $1 million for primelien U.S. RMBS transactions.

In the Company's least stressful scenario where the CDR plateau was six months shorter (30 months, effectively assuming that liquidation rates would improve) and the CDR recovery was more pronounced (including an initial ramp-down of the CDR over nine months), expected loss to be paid would decrease from current projections by approximately $13$33 million for Alt-Aall first liens, $22 million for Option ARM, $25 million for subprime and $0.1 million for primelien U.S. RMBS transactions.
 
U.S. Second Lien RMBS Loss Projections
 
Second lien RMBS transactions include both home equity lines of credit (HELOC) and closed end second lien.lien mortgages. The Company believes the primary variable affecting its expected losses in second lien RMBS transactions is the amount and timing of future losses in the collateral pool supporting the transactions. Expected losses are also a function of the structure of the transaction;transaction, the voluntary prepayment rate (typically also referred to as CPR of the collateral);, the interest rate environment;environment, and assumptions about the draw rate and loss severity.
 
In second lien transactions the projection of near-term defaults from currently delinquent loans is relatively straightforward because loans in second lien transactions are generally “charged off” (treated as defaulted) by the securitization’s servicer once the loan is 180 days past due. The Company estimates the amount of loans that will default over the next six months by calculating current representative liquidation rates. A liquidation rate is the percent of loans in a given cohort (in this instance, delinquency category) that ultimately default. Similar to first liens, the Company then calculates a CDR for six months, which is the period over which the currently delinquent collateral is expected to be liquidated. That CDR is then used as the basis for the plateau CDR period that follows the embedded five months ofplateau losses.

For the base case scenario, the CDR (the plateau CDR) was held constant for six months. Once the plateau period has ended, the CDR is assumed to gradually trend down in uniform increments to its final long-term steady state CDR. (The long-term steady state CDR is calculated as the constant CDR that would have yielded the amount of losses originally expected at underwriting.) In the base case scenario, the time over which the CDR trends down to its final CDR is 28 months. Therefore, the total stress period for second lien transactions is 34 months, comprisingrepresenting six months of delinquent data andloan liquidations, followed by 28 months of decrease to the steady state CDR, the same as of December 31, 2015.2017.

HELOC loans generally permit the borrower to pay only interest for an initial period (often ten years) and, after that period, require the borrower to make both the monthly interest payment and a monthly principal payment, and so increasepayment. This causes the borrower's aggregatetotal monthly payment. Somepayment to increase, sometimes substantially, at the end of the initial interest-only period. In the prior periods, as the HELOC loans underlying the Company's insured HELOC transactions have reached their principal amortization period. Theperiod, the Company has observed that the increase in monthly payments occurring when a loan reaches its principal amortization period, even if mitigated by borrower relief offered by the servicer, is associated with increased borrower defaults. Thus, most of the Company's HELOC projections incorporateincorporated an assumption that a percentage of loans reaching their principal amortization periods willwould default around the time of the payment increase. These projected defaults

The HELOC loans underlying the Company's insured HELOC transactions are now past their original interest-only reset date, although a significant number of HELOC loans were modified to extend the original interest-only period for another five years. As a result, in addition to those generated using2017, the Company eliminated the CDR curve as described above. This assumption is similar toincrease that was applied when such loans reached their principal amortization period. In addition, based on the one used asaverage performance history, starting in the third quarter of December 31, 2015.2017, the Company applied a CDR floor of 2.5% for the future steady state CDR on all its HELOC transactions.

When a second lien loan defaults, there is generally a very low recovery. The Company assumed as of December 31, 20162018 that it will generally recover only 2% of future defaulting collateral at the collateral defaulting in the future and decliningtime of charge-off, with additional amounts of post-default receipts on previously defaulted collateral.post charge-off recoveries assumed to come in over time. This is the same assumption used as of December 31, 2015.2017. A second lien on the borrower’s home may be retained in the Company's second lien transactions after the loan is charged off and the loss applied to the transaction, particularly in cases where the holder of the first lien has not foreclosed. If the second lien is retained and the value of the home increases, the servicer may be able to use the second lien to increase recoveries, either by arranging for the borrower to resume payments or by realizing value upon the sale of the underlying real estate.  In instances where the Company is able to obtain information on the lien status of charged-off loans, it assumes future recoveries of 10% of the balance of the charged off loans where the second lien is still intact. The Company assumes the recoveries are received evenly over the next five years, although actual recoveries will vary. The Company evaluates its assumptions periodically based on actual recoveries of charged off loans.

The rate at which the principal amount of loans is prepaid may impact both the amount of losses projected as well as the amount of excess spread. In the base case, an average CPR (based on experience of the past year) is assumed to continue

until the end of the plateau before gradually increasing to the final CPR over the same period the CDR decreases. The final CPR is assumed to be 15% for second lien transactions (in the base case), which is lower than the historical average but reflects the Company’s continued uncertainty about the projected performance of the borrowers in these transactions. For transactions where the initial CPR is higher than the final CPR, the initial CPR is held constant and the final CPR is not used. This pattern is generally

consistent with how the Company modeled the CPR as of December 31, 2015.2017. To the extent that prepayments differ from projected levels it could materially change the Company’s projected excess spread and losses.
 
The Company uses a number of other variables in its second lien loss projections, including the spread between relevant interest rate indices. These variables have been relatively stable and in the relevant ranges have less impact on the projection results than the variables discussed above. However, in a number of HELOC transactions the servicers have been modifying poorly performing loans from floating to fixed rates, and, as a result, rising interest rates would negatively impact the excess spread available from these modified loans to support the transactions.  The Company incorporated these modifications in its assumptions.

In estimating expected losses, the Company modeled and probability weighted five possiblescenarios, each with a different CDR curvescurve applicable to the period preceding the return to the long-term steady state CDR. The Company used five scenarios at December 31, 2016 and December 31, 2015. The Company believes that the level of the elevated CDR and the length of time it will persist and the ultimate prepayment rate and the amount of additional defaults because of the expiry of the interest only period, are the primary drivers behind the likely amount of losses the collateral will suffer.

The Company continues to evaluate the assumptions affecting its modeling results.

The Company believes the most important driver of its projected second lien RMBS losses is the performance of its HELOC transactions. Total expected loss to be paid on all second lien U.S. RMBS was $50 million as of December 31, 2018 and total expected recovery on all second lien U.S. RMBS was $50 million as of December 31, 2017, respectively. This change was primarily due to cash received in 2018 from a favorable settlement of R&W litigation reached in late December 2017 and the addition of $17 million of net expected loss on second lien U.S. RMBS from reinsurance of the SGI portfolio on June 1, 2018 and partially offset by improvement in the performance of primarily HELOC transactions.

The following table shows the range as well as the average, weighted by outstanding net insured par, for key assumptions for the calculation of expected loss to be paid for individual transactions for direct vintage 2004 - 2008 HELOCs.

(1)Represents variables for most heavily weighted scenario (the base case).      
    

The Company’s base case assumed a six month CDR plateau and a 28 month ramp-down (for a total stress period of 34 months). The Company also modeled a scenario with a longer period of elevated defaults and another with a shorter period of elevated defaults. IncreasingIn the Company's most stressful scenario, increasing the CDR plateau to eight months and increasing the ramp-down by three months to 31 months (for a total stress period of 39 months), and doubling the defaults relating to the end of the interest only period would increase the expected loss by approximately $39$9 million for HELOC transactions. On the other hand, in the Company's least stressful scenario, reducing the CDR plateau to four months and decreasing the length of the CDR ramp-down to 25 months (for a total stress period of 29 months), and lowering the ultimate prepayment rate to 10% would decrease the expected loss by approximately $23$10 million for HELOC transactions.


Breaches of Representations and Warranties
The Company entered into agreements with R&W providers under which those providers made payments to the Company, agreed to make payments to the Company in the future, and / or repurchased loans from the transactions, all in return for releases of related liability by the Company. As of December 31, 2016, the Company had two such agreements remaining. Under the Company's agreement with Bank of America Corporation and certain of its subsidiaries (Bank of America), Bank of America agreed to reimburse the Company for 80% of claims on the first lien transactions covered by the agreement that the Company pays in the future, subject to a cap the Company currently projects it will not reach. Under the Company’s agreement with UBS Real Estate Securities Inc. and affiliates (UBS), UBS agreed to reimburse the Company for 85% of future losses on three first lien RMBS transactions. Bank of America and UBS have posted collateral to secure their obligations under these agreements. The Company also had an R&W reimbursement agreement with Deutsche Bank AG and certain of its affiliates (collectively, Deutsche Bank), but Deutsche Bank's reimbursement obligations under that agreement were terminated in May 2016 in return for a cash payment to the Company. The Company uses the same RMBS projection scenarios and weightings to project its future R&W benefit or payable as it uses to project RMBS losses on its portfolio.

As of December 31, 2016, the Company had a net R&W payable of $6 million to R&W counterparties, compared to an R&W recoverable of $79 million as of December 31, 2015. The decrease represents improvements in underlying collateral performance and the termination of the Deutsche Bank agreement described above, partially offset by the addition of R&W recoverable related to a RMBS insured by CIFGNA and still being pursued by the Company. The Company’s agreements with providers of R&W generally provide for reimbursement to the Company as claim payments are made and, to the extent the Company later receives reimbursements of such claims from excess spread or other sources, for the Company to provide reimbursement to the R&W providers. When the Company projects receiving more reimbursements in the future than it projects to pay in claims on transactions covered by R&W settlement agreements, the Company will have a net R&W payable.

Triple-X Life Insurance TransactionsOther Structured Finance
 
The Company had $2.1$1.2 billion of net par exposure to financial guaranty Triple-Xtriple-X life insurance transactions as of December 31, 2016. Two2018, of these transactions, with $126which $85 million ofin net par outstanding, areis rated BIG. The Triple-Xtriple-X life insurance transactions are based on discrete blocks of individual life insurance business. In older vintage Triple-Xtriple-X life insurance transactions, which include the two BIG-rated transactions, the amounts raised by the sale of the notes insured by the Company were used to capitalize a special purpose vehicle that provides reinsurance to a life insurer or reinsurer. The amounts arehave been invested atsince inception in accounts managed by third-party investment managers. In the case of the two BIG-rated transactions, material amounts of their assets were invested in U.S. RMBS. Based on its analysis of the information currently available, including estimates of future investment performance, and projected credit impairments on the invested assets and performance of the blocks of life insurance business at December 31, 2016, the Company’s projected net expected loss to be paid is $54 million. The economic benefit during 2016 was approximately $22 million, which was due primarily to a benefit resulting from a purchase of a portion of an insured obligation to mitigate loss.

Student Loan Transactions
The Company has insured or reinsured $1.4$1.1 billion net par of student loan securitizations issued by private issuers and that it classifiesare classified as structured finance. Of this amount, $109$96 million is rated BIG. The Company is projecting approximately $32 million of net expected loss to be paid on these transactions. In general, the projected losses are due to: (i) the poor credit performance of private student loan collateral and high loss severities, or (ii) high interest rates on auction rate securities with respect to which the auctions have failed. The economic benefit during 2016 was approximately $14 million, which was driven primarily by the commutation of certain assumed student loan exposures earlier in the year.

Recovery Litigation

In the ordinary course of their respective businesses, certain of AGL's subsidiaries assert claims in legal proceedings against third parties to recover losses paid in prior periods or prevent losses in the future. 

Public Finance Transactions

On January 7, 2016, AGM, AGC and Ambac Assurance Corporation (Ambac) commenced an actionThe Company has asserted claims in a number of legal proceedings in connection with its exposure to Puerto Rico. See Note 4, Outstanding Exposure, for declaratory judgment and injunctive relief in the U.S. District Court for the District of Puerto Rico to invalidate the executive orders issued by the Governor on November 30, 2015 and December 8, 2015 directing that the Secretary of the Treasury of the Commonwealth of Puerto Rico and the Puerto Rico Tourism Company retain or transfer (in other words, claw back) certain taxes and revenues pledged to secure the payment of bonds issued by the PRHTA, the PRCCDA and the PRIFA. The Commonwealth defendants filed a motion to dismiss the action for lack of subject matter jurisdiction, which the Court denied on October 4, 2016. On October 14, 2016, the Commonwealth defendants filed a notice of PROMESA automatic stay.

On July 21, 2016, AGC and AGM filed a motion and form of complaint in the U.S. District Court for the District of Puerto Rico seeking relief from the stay provided by PROMESA. Upon a grant of relief from the PROMESA stay, the lawsuit further seeks a declaration that the Moratorium Act is preempted by Federal bankruptcy law and that certain gubernatorial executive orders diverting PRHTA pledged toll revenues (which are not subject to the Clawback) are preempted by PROMESA and violate the U.S. Constitution. Additionally, it seeks damages for the value of the PRHTA toll revenues diverted and injunctive relief prohibiting the defendants from taking any further action under these executive orders. On October 28, 2016, the Oversight Board filed a motion seeking leave to intervene in the action, which motion was denied on November 1, 2016, without prejudice, on procedural grounds. On November 2, 2016, the Court denied AGC’s and AGM’s motion for relief from the PROMESA stay on procedural grounds. The PROMESA stay expires on May 1, 2017.

On November 1, 2013, Radian Asset Assurance Inc. commenced a declaratory judgment action in the U.S. District Court for the Southern District of Mississippi against Madison County, Mississippi (the County) and the Parkway East Public Improvement District (District) to establish its rights under a contribution agreement from the County supporting certain special assessment bonds issued by the District and insured by Radian Asset Assurance Inc. (now AGC). As of December 31, 2016, $202018, $18 million of such bonds were outstanding. The County maintained that its payment obligation is limited to two years of annual debt service, while AGC contended the County’s obligations under the contribution agreement continue so long as the bonds remain outstanding. On April 27, 2016, the Courtdistrict court granted AGC's motion for summary judgment, agreeing with AGC's interpretation of the County's obligations.

Morgan Investment Management Inc. (JPMIM),properties that have defaulted, and on May 11, 2018, the investment managerdistrict court dismissed the case. The settlement agreement also provides for a triple-X life insurance transaction, Orkney Re II plc (Orkney), involving securities guaranteed by AGUK. As of December 31, 2016, the Company insures $423 million net par of Orkney securities. The action alleges that JPMIM engaged in breaches of fiduciary duty, gross negligence and breaches of contract based upon its handlingCounty owned property to be conveyed to the District, which, to the extent practicable, is obligated to lease, sell or otherwise dispose of the Orkney investments. After AGUK’s claims were dismissed with prejudice in January 2010, AGUK was successful in its subsequent motions and appeals and, as of December 2011, all of AGUK’s claims for breaches of fiduciary duty, gross negligence and contract were reinstated in full. On January 22, 2016, AGUK filed a motion for partial summary judgment with respectproperty to one of its claims for breach of contract relating to a failure to invest in compliance with the Delaware Insurance Code. On February 21, 2017, the court issued a decision on the motion. While the court denied the motion on the ground that the gross negligence of JPMIM in breaching the contract was a fact issue to be decided at trial, the court did find as a matter of law that JPMIM breached the contract relating to a failure to invest in compliance with the Delaware Insurance Code. A trial date has been set for mid-March 2017.maximize pledged revenues. Any such actions will require AGC’s consent.

RMBS Transactions

On February 5, 2009, U.S. Bank National Association, as indenture trustee (U.S. Bank), CIFGNA, as insurer of the Class Ac Notes, and Syncora Guarantee Inc. (Syncora), as insurer of the Class Ax Notes, filed a complaint in the Supreme Court of the State of New York against GreenPoint Mortgage Funding, Inc. (GreenPoint) alleging GreenPoint breached its R&W with respect to the underlying mortgage loans in the GreenPoint Mortgage Funding Trust 2006-HE1 transaction. On March 3, 2010, the court dismissed CIFGNA's and Syncora’s causes of action on standing grounds. On December 16, 2013, GreenPoint moved to dismiss the remaining claims of U.S. Bank on the grounds that it too lacked standing. U.S. Bank cross-moved for partial summary judgment striking GreenPoint’s defense that U.S. Bank lacked standing to directly pursue claims against GreenPoint. On January 28, 2016, the court denied GreenPoint’s motion for summary judgment and granted U.S.

Bank’s cross-motion for partial summary judgment, finding that as a matter of law U.S. Bank has standing to directly assert claims against GreenPoint.  On November 28, 2016, GreenPoint filed an appeal. CIFGNA originally had $500 million insured net par exposure to this transaction; $23 million insured net par remains outstanding at December 31, 2016.

On November 26, 2012, CIFGNA filed a complaint in the Supreme Court of the State of New York against JP Morgan Securities LLC (JP Morgan) for material misrepresentation in the inducement of insurance and common law fraud, alleging that JP Morgan fraudulently induced CIFGNA to insure $400 million of securities issued by ACA ABS CDO 2006-2 Ltd. and $325 million of securities issued by Libertas Preferred Funding II, Ltd. On June 26, 2015, the Courtcourt dismissed with prejudice CIFGNA’s material misrepresentation in the inducement of insurance claim and dismissed without prejudice CIFGNA’s common law fraud claim. On September 24, 2015, the Courtcourt denied CIFGNA’s motion to amend but allowed CIFGNA to re-plead a cause of action for common law fraud. On November 20, 2015, CIFGNA filed a motion for leave to amend its complaint to re-plead common law fraud. On April 29, 2016, CIFGNA filed an appeal to reverse the Court’scourt’s decision dismissing CIFGNA’s material misrepresentation in the inducement of insurance claim. On November 29, 2016, the Appellate Division of the Supreme Court of the State of New York ruled that the Court’scourt’s decision dismissing with prejudice CIFGNA’s material

misrepresentation in the inducement of insurance claim should be modified to grant CIFGNA leave to repleadre-plead such claim.

On January 15, 2013, CIFGNAFebruary 27, 2017, AGC (as successor to CIFGNA) filed an amended complaint which includes a complaint in the Supreme Court of the State of New York against Goldman, Sachs & Co.

CDO. CIFGNA and Goldman agreed to separately arbitrate the issue of liability with respect to CIFG’s purchase of the Class A-2 Notes, and on February 4, 2015, an arbitration panel awarded CIFGNA $2.5 million in damages. On September 11, 2015, CIFGNA filed an amended complaint to allege that the arbitration award collaterally estopped Goldman from disputing its liability for fraudulent inducement in respect of the Class A-1 Notes.

Accounting for financial guaranty contracts that meet the scope exception under derivative accounting guidance are subject to industry specific guidance for financial guaranty insurance. The accounting for contracts that fall under the financial guaranty insurance definition are consistent whether the contract wascontracts are written on a direct basis, assumed from another financial guarantor under a reinsurance treaty, ceded to another insurer under a reinsurance treaty, or acquired in a business combination.

Premiums receivable compriserepresent the present value of contractual or expected future premium collections discounted using the risk-free rate.risk free rates. Unearned premium reserve represents deferred premium revenue, less claim payments made and recoveries received that have not yet been recognized in the statement of operations (contra-paid). The following discussion relates to the deferred premium revenue component of the unearned premium reserve, while the contra-paid is discussed below under "Financial Guaranty Insurance Losses."

The amount of deferred premium revenue at contract inception is determined as follows:

For premiums received upfront on financial guaranty insurance contracts that were originally underwritten by the Company, deferred premium revenue is equal to the amount of cash received. Upfront premiums typically relate to public finance transactions.

For premiums received in installments on financial guaranty insurance contracts that were originally underwritten by the Company, deferred premium revenue is the present value (discounted at risk free rates) of either (1) contractual premiums due or (2) in cases where the underlying collateral is comprisedcomposed of homogeneous pools of assets, the expected premiums to be

collected over the life of the contract. To be considered a homogeneous pool of assets, prepayments must be contractually prepayable,allowable, the amount of prepayments must be probable, and the timing and amount of prepayments must be reasonably estimable. When the Company adjusts prepayment assumptions or expected premium collections, an adjustment is recorded to the deferred premium revenue, with a corresponding adjustment to the premium receivable, and prospective changes are recognized in premium revenues. Premiums receivable are discounted at the risk-free rate at inception and such discount rate is updated only when changes to prepayment assumptions are made that change the expected date of final maturity. Installment premiums typically relate to structured finance transactions, where the insurance premium rate is determined at the inception of the contract but the insured par is subject to prepayment throughout the life of the transaction.

For financial guaranty insurance contracts acquired in a business combination, deferred premium revenue is equal to the fair value of the Company's stand-ready obligation portion of the insurance contract at the date of acquisition based on what a hypothetical similarly rated financial guaranty insurer would have charged for the contract at that date and not the actual cash flows under the insurance contract. The amount of deferred premium revenue may differ significantly from cash collections primarily due primarily to fair value adjustments recorded in connection with a business combination.

When the Company adjusts prepayment assumptions or expected premium collections, an adjustment is recorded to the deferred premium revenue, with a corresponding adjustment to the premium receivable. Premiums receivable are discounted at the risk-free rate at inception and such discount rate is updated only when changes to prepayment assumptions are made that change the expected date of final maturity.

The Company recognizes deferred premium revenue as earned premium over the contractual period or expected period of the contract in proportion to the amount of insurance protection provided. As premium revenue is recognized, a corresponding decrease to the deferred premium revenue is recorded. The amount of insurance protection provided is a function of the insured principal amount outstanding. Accordingly, the proportionate share of premium revenue recognized in a given reporting period is a constant rate calculated based on the relationship between the insured principal amounts outstanding in the reporting period compared with the sum of each of the insured principal amounts outstanding for all periods. When an insured

financial obligation is retired before its maturity, the financial guaranty insurance contract is extinguished. Any nonrefundable deferred premium revenue related to that contract is accelerated and recognized as premium revenue. When a premium receivable balance is deemed uncollectible, it is written off to bad debt expense.

For assumed reinsurance assumed contracts, net earned premiums reported in the Company's consolidated statements of operations are calculated based upon data received from ceding companies,companies; however, some ceding companies report premium data between 30 and 90 days after the end of the reporting period. The Company estimates net earned premiums for the lag period.  Differences between such estimates and actual amounts are recorded in the period in which the actual amounts are determined. When installment premiums are related to assumed reinsurance assumed contracts, the Company assesses the credit quality and liquidity of the ceding companies and the impact of any potential regulatory constraints to determine the collectability of such amounts.

Financial Guaranty Insurance Acquisition Costs

Accounting Policy

Policy acquisition costs that are directly related and essential to successful insurance contract acquisition, andas well as ceding commission income and expense on ceded and assumed reinsurance contracts, are deferred for contracts accounted for as insurance, and reported net. Amortization of deferred policy acquisition costs includes the accretion of discount on ceding commission income and expense.

Capitalized policy acquisition costs include expenses such as ceding commissions expense on assumed reinsurance contracts and the cost of underwriting personnel attributable to successful underwriting efforts. Management uses its judgment in determining the type and amount of costs to be deferred. The Company conducts an annual study to determine deferral rates.

Ceding commission expense on assumed reinsurance contracts and ceding commission income on ceded reinsurance contracts that are associated with premiums received in installments are calculated at their contractually defined commission rates, discounted consistent with premiums receivable for all future periods, and included in deferred acquisition costs (DAC), with a corresponding offset to net premiums receivable or reinsurance balances payable. Management uses its judgment in determining the type and amount of costs to be deferred. The Company conducts an annual study to determine which operating costs qualify for deferral. Costs


DAC is amortized in proportion to net earned premiums. Amortization of deferred policy acquisition costs includes the accretion of discount on ceding commission receivable and payable. When an insured obligation is retired early, the remaining related DAC is recognized at that time. Costs incurred for soliciting potential customers, market research, training, administration, unsuccessful acquisition efforts, and product development as well as all overhead type costs are charged to expense as incurred. DAC is amortized in proportion to net earned premiums. When an insured obligation is retired early, the remaining related DAC, net of ceding commission income is recognized at that time.
 
Expected losses and LAE, investment income, and the remaining costs of servicing the insured or reinsured business, are considered in determining the recoverability of DAC.

Financial Guaranty Insurance Losses

Accounting Policies

Loss and LAE Reserve

Loss and LAE reserve reported on the balance sheet relates only to direct and assumed reinsurance contracts that are accounted for as insurance, substantially all of which are financial guaranty insurance contracts. The corresponding reserve ceded to reinsurers is reported as reinsurance recoverable on unpaid losses.losses and reported in other assets. As discussed in Note 7, Fair Value Measurement, contracts that meet the definition of a derivative, as well as consolidated FG VIEVIEs’ assets and liabilities, are recorded separately at fair value. Any expected losses related to consolidated FG VIEs are eliminated upon consolidation. Any expected losses on credit derivatives are not recorded as loss and LAE reserve on the consolidated balance sheet, rather, credit derivatives are recorded at fair value on the balance sheet.
    
Under financial guaranty insurance accounting, the sum of unearned premium reserve and loss and LAE reserve represents the Company's stand‑ready obligation. Unearned premium reserve is deferred premium revenue, less claim payments and recoveries received that have not yet been recognized in the statement of operations (contra-paid). At contract inception, the entire stand-ready obligation is represented by unearned premium reserve. A loss and LAE reserve for an insurance contract is recorded only to the extent, and for the amount, that expected loss to be paid net ofplus contra-paid (“total losses”) exceed the deferred premium revenue, on a contract by contract basis. As a result, the Company has expected loss to be paid that has not yet been expensed. Such amounts will be recognized in future periods as deferred premium revenue amortizes into income.
When a claim or LAE payment is made on a contract, it first reduces any recorded loss and LAE reserve. To the extent there is no loss and LAE reserve on a contract, then such claim payment is recorded as “contra-paid,” which reduces the unearned premium reserve. The contra-paid is recognized in the line item “loss and LAE” in the consolidated statement of operations when and for the amount that total losses exceed the remaining deferred premium revenue on the insurance contract. Loss and LAE in the consolidated statement of operations is presented net of cessions to reinsurers.


Salvage and Subrogation Recoverable

When the Company becomes entitled to the cash flow from the underlying collateral of an insured creditexposure under salvage and subrogation rights as a result of a claim payment or estimated future claim payment, it reduces the expected loss to be paid on the contract. Such reduction in expected loss to be paid can result in one of the following:

a reduction in the corresponding loss and LAE reserve with a benefit to the income statement,

no entry recorded, if “total loss” is not in excess of deferred premium revenue, or

the recording of a salvage asset with a benefit to the income statement if the transaction is in a net recovery position at the reporting date.

The Company recognizes the expected recovery of claim payments (including recoveries from settlement with R&W providers) made by an acquired subsidiary prior to the date of acquisition, consistent with its policy for recognizing recoveries on all financial guaranty insurance contracts. To the extent that the estimated amount of recoveries increases or decreases due to changes in facts and circumstances the Company would recognize a benefit or expense consistent with how changes in the expected recovery of all other claim payments are recorded. The ceded component of salvage and subrogation recoverable is recorded in the line item reinsurance balances payable.other liabilities.

Expected Loss to be Expensed

Expected loss to be expensed represents past or expected future net claim payments that have not yet been expensed. Such amounts will be expensed in future periods as deferred premium revenue amortizes into income on financial guaranty insurance policies. Expected loss to be expensed is the Company's projection of incurred losses that will be recognized in future periods, excluding accretion of discount.


Insurance Contracts' Loss Information

The following table provides information on net reserve (salvage), which includes loss and LAE reserves and salvage and subrogation recoverable, both net of reinsurance. TheTo discount loss reserves, the Company used risk-free rates for U.S. dollar denominated financial guaranty insurance obligations that ranged from 0.0% to 3.23%3.06% with a weighted average of 2.74% as of December 31, 20162018 and from 0.0% to 3.25%2.78% with a weighted average of 2.37%2.39% as of December 31, 2015.2017.

The table below provides a reconciliation of net expected loss to be paid to net expected loss to be expensed. Expected loss to be paid differs from expected loss to be expensed due to: (i) the contra-paid which represent the claim payments made and recoveries received that have not yet been recognized in the statement of operations, (ii) salvage and subrogation recoverable for transactions that are in a net recovery position where the Company has not yet received recoveries on claims previously paid (having the effect of reducing net expected loss to be paid by the amount of the previously paid claim and the expected recovery), but will have no future income effect (because the previously paid claims and the corresponding recovery of those claims will offset(and therefore recognized in income in future periods)but not yet received), and (iii) loss reserves that have already been established (and therefore expensed but not yet paid).

Ratings Impact on Financial Guaranty Business
 
A downgrade of one of AGL’s insurance subsidiaries may result in increased claims under financial guaranties issued by the Company if counterparties exercise contractual rights triggered by the downgrade against insured obligors, and the insured obligors wereare unable to pay.
 
For example, AGM has issued financial guaranty insurance policies in respect of the obligations of municipal obligors under interest rate swaps. AGM insures periodic payments owed by the municipal obligors to the bank counterparties. In certain cases, AGM also insures termination payments that may be owed by the municipal obligors to the bank counterparties. If (i) AGM has been downgraded below the rating trigger set forth in a swap under which it has insured the termination payment, which rating trigger varies on a transaction by transaction basis; (ii) the municipal obligor has the right to cure by, but has failed in, posting collateral, replacing AGM or otherwise curing the downgrade of AGM; (iii) the transaction documents include as a condition that an event of default or termination event with respect to the municipal obligor has occurred, such as the rating of the municipal obligor being downgraded past a specified level, and such condition has been met; (iv) the bank counterparty has elected to terminate the swap; (v) a termination payment is payable by the municipal obligor; and (vi) the municipal obligor has failed to make the termination payment payable by it, then AGM would be required to pay the termination payment due by the municipal obligor, in an amount not to exceed the policy limit set forth in the financial guaranty insurance policy. At AGM's current financial strength ratings, if the conditions giving rise to the obligation of AGM to make a termination payment under the swap termination policies were all satisfied, then AGM could pay claims in an amount

not exceeding approximately $125 million in respect of such termination payments. Taking into consideration whether the rating of the municipal obligor is below any applicable specified trigger, if the financial strength ratings of AGM were further downgraded below "A" by S&P or below "A2" by Moody's, and the conditions giving rise to the obligation of AGM to make a payment under the swap policies were all satisfied, then AGM could pay claims in an additional amount not exceeding approximately $291$212 million in respect of such termination payments.
     

As another example, with respect to variable rate demand obligations (VRDOs) for which a bank has agreed to provide a liquidity facility, a downgrade of AGM or AGC may provide the bank with the right to give notice to bondholders that the bank will terminate the liquidity facility, causing the bondholders to tender their bonds to the bank. Bonds held by the bank accrue interest at a “bank bond rate” that is higher than the rate otherwise borne by the bond (typically the prime rate plus 2.00% — 3.00%, and capped at the lesser of 25% and the maximum legal limit). In the event the bank holds such bonds for longer than a specified period of time, usually 90-180 days, the bank has the right to demand accelerated repayment of bond principal, usually through payment of equal installments over a period of not less than five years. In the event that a municipal obligor is unable to pay interest accruing at the bank bond rate or to pay principal during the shortened amortization period, a claim could be submitted to AGM or AGC under its financial guaranty policy. As of December 31, 20162018, AGM and AGC had insured approximately $4.9$4.5 billion net par of VRDOs, of which approximately $0.3 billion$53 million of net par constituted VRDOs issued by municipal obligors rated BBB- or lower pursuant to the Company’s internal rating. The specific terms relating to the rating levels that trigger the bank’s termination right, and whether it is triggered by a downgrade by one rating agency or a downgrade by all rating agencies then rating the insurer, vary depending on the transaction.

In addition, AGM may be required to pay claims in respect of AGMH’s former financial products business if Dexia SA and its affiliates, from which the Company had purchased AGMH and its subsidiaries, do not comply with their obligations following a downgrade of the financial strength rating of AGM. A downgrade of the financial strength rating of AGM could trigger a payment obligation of AGM in respect to AGMH's former GICguaranteed investment contracts (GIC) business. Most GICs insured by AGM allow for the termination of the GIC contract and a withdrawal of GIC funds at the option of the GIC holder in the event of a downgrade of AGM below a specified threshold, generally below A- by S&P or A3 by Moody's. FSAMAGMH's former subsidiary FSA Asset Management LLC is expected to have sufficient eligible and liquid assets to satisfy any expected withdrawal and collateral posting obligations resulting from future rating actions affecting AGM.

7.Fair Value Measurement
 
The Company carries a significant portion of its assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., exit price). The price represents the price available in the principal market for the asset or liability. If there is no principal market, then the price is based on a hypothetical market that maximizes the value received for an asset or minimizes the amount paid for a liability (i.e., the most advantageous market).
 
Fair value is based on quoted market prices, where available. If listed prices or quotes are not available, fair value is based on either internally developed models that primarily use, as inputs, market-based or independently sourced market parameters, including but not limited to yield curves, interest rates and debt prices or with the assistance of an independent third-party using a discounted cash flow approach and the third party’s proprietary pricing models. In addition to market information, models also incorporate transaction details, such as maturity of the instrument and contractual features designed to reduce the Company’s credit exposure, such as collateral rights as applicable.
 
Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments include amounts to reflect counterparty credit quality, the Company’s creditworthiness and constraints on liquidity. As markets and products develop and the pricing for certain products becomes more or less transparent, the Company may refine its methodologies and assumptions. During 2016,2018, no changes were made to the Company’s valuation models that had or are expected to have, a material impact on the Company’s consolidated balance sheets or statements of operations and comprehensive income.
 
The Company’s methods for calculating fair value produce a fair value that may not be indicative of net realizable value or reflective of future fair values. The use of different methodologies or assumptions to determine fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.
 
The categorization within the fair value hierarchy is determined 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 estimates of market assumptions. The fair value hierarchy prioritizes

model inputs into three broad levels as follows, with Level 1 being the highest and Level 3 the lowest. An assetasset's or liability’s categorization is based on the lowest level of significant input to its valuation.

Level 1—Quoted prices for identical instruments in active markets. The Company generally defines an active market as a market in which trading occurs at significant volumes. Active markets generally are more liquid and have a lower bid-ask spread than an inactive market.
 

Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and observable inputs other than quoted prices, such as interest rates or yield curves and other inputs derived from or corroborated by observable market inputs.
 
Level 3—Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. Level 3 financial instruments also include those for which the determination of fair value requires significant management judgment or estimation.

Transfers between Levels 1, 2 and 3 are recognized at the end of the period when the transfer occurs. The Company reviews the classification between Levels 1, 2 and 3 quarterly to determine whether a transfer is necessary. During the periods
presented, there were no transfers betweeninto or from Level 1 and Level 2. There were transfers of fixed-maturity securities3 except for one transfer from Level 2 into Level 3 during 20162017 because starting in the second quarter of 2017 the price of the security includes a lack of observability relating to the valuation inputs and collateral pricing. There were no transfers into or out of Level 3 during 2015.significant unobservable assumption.
 
Measured and Carried at Fair Value
 
Fixed-Maturity Securities and Short-Term Investments
 
The fair value of bonds in the investment portfolio is generally based on prices received from third party pricing services or alternative pricing sources with reasonable levels of price transparency. The pricing services prepare estimates of fair value measurements using their pricing models, which include available relevant market information,take into account: benchmark curves, benchmarking of likeyields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, industry and economic events and sector groupings. Additional valuation factors that can be taken into account are nominal spreads and liquidity adjustments. The pricing services evaluate each asset class based on relevant market and credit information, perceived market movements, and sector news. The market inputs used in the pricing evaluation include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data and industry and economic events.

Benchmark yields have in many cases taken priority over reported trades for securities that trade less frequently or those that are distressed trades, and therefore may not be indicative of the market. The extent of the use of each input is dependent on the asset class and the market conditions. Given the asset class, the priority of the use of inputs may change or some market inputs may not be relevant. Additionally, theThe valuation of fixed-maturity investments is more subjective when markets are less liquid due to the lack of market based inputs, which may increase the potential that the estimated fair value of an investment is not reflective of the price at which an actual transaction would occur.inputs.
    
Short-term investments that are traded in active markets are classified within Level 1 in the fair value hierarchy and their value is based on quoted market prices. Securities such as discount notes are classified within Level 2 because these securities are typically not actively traded due to their approaching maturity and, as such, their cost approximates fair value. Short term securities that were obtained as part of loss mitigation efforts and whose prices were determined based on models, where at least one significant model assumption or input is unobservable, are considered to be Level 3 in the fair value hierarchy.
Annually, the Company reviews each pricing service’s procedures, controls and models used in the valuations of the Company’s investment portfolio, as well as the competency of the pricing service’s key personnel. In addition, on a quarterly basis, the Company holds a meeting of the internal valuation committee (comprised of individuals within the Company with market, valuation, accounting, and/or finance experience) that reviews and approves prices and assumptions used by the pricing services.

For Level 1 and 2 securities, the Company, on a quarterly basis, reviews internally developed analytic packages that highlight, at a CUSIP level, price changes from the previous quarter to the current quarter. Where unexpected price movements are noted for a specific CUSIP, the Company formally challenges the price provided, and reviews all key inputs utilized in the third party’s pricing model, and compares such information to management’s own market information.


For Level 3 securities, the Company, on a quarterly basis:

reviews methodologies, any model updates and inputs and compares such information to management’s own market information and, where applicable, the internal models,

reviews internally developed analytic packages that highlight, at a CUSIP level, price changes from the previous quarter to the current quarter, and evaluates, documents, and resolves any significant pricing differences with the assistance of the third party pricing source, and

compares prices received from different third party pricing sources, and evaluates, documents the rationale for, and resolves any significant pricing differences.
As of December 31, 2016,2018, the Company used models to price 80 fixed-maturity123 securities, (primarilyprimarily securities that were purchased or obtained for loss mitigation or other risk management purposes), which were 11.7% or $1,269 millionpurposes, with a fair value of the Company’s fixed-maturity securities and short-term investments at fair value.$1,411 million. Most Level 3 securities were priced with the assistance of an independent third-party. The pricing is based on a discounted cash flow approach using the third-party’s proprietary pricing models. The models use inputs such as projected prepayment speeds;  severity assumptions; recovery lag assumptions; estimated default rates (determined on the basis of an analysis of collateral attributes, historical collateral performance, borrower profiles and other features relevant to the evaluation of collateral credit quality); home price appreciation/depreciation rates based on macroeconomic forecasts and recent trading activity. The yield used to discount the projected cash flows is determined by reviewing various attributes of the bondsecurity including collateral type, weighted average life, sensitivity to losses, vintage, and convexity, in conjunction with market data on comparable securities. Significant changes to any of these inputs could have materially changechanged the expected timing of cash flows within these securities which is a significant factor in determining the fair value of the securities.
 
Other Invested Assets
 
As of December 31, 20162018 and December 31, 2015,2017, other invested assets includeincluded investments carried and measured at fair value on a recurring basis of $52$3 million and $53$48 million, respectively, and includerespectively. December 31, 2017 included primarily an investmentpreferred stock investments in the global property catastrophe risk market and an investment in a fund that investsinvested primarily in senior loans and bonds.bonds, which were sold in 2018. Fair values for the majority of thesepreferred stock investments arewere based on their respective net asset value (NAV) per share or equivalent. Included in the amounts above are other equity investments that were carried at their fair value of $2 million as of December 31, 2018 and December 31, 2017. These equity investments were classified as Level 3.
 

Other Assets
 
Committed Capital Securities
 
The fair value of committed capital securities (CCS), which is recorded in “other assets” on the consolidated balance sheets, represents the difference between the present value of remaining expected put option premium payments under AGC’sAGC CCS (the AGC CCS) and AGM’s Committed Preferred Trust Securities (the AGM CPS) agreements, and the estimated present value that the Company would hypothetically have to pay currently for a comparable security (see Note 16, Long Term Debt and Credit Facilities). The AGC CCS and AGM CPS are carried at fair value with changes in fair value recorded in other income in the consolidated statement of operations. The estimated current cost of the Company’s CCS is based on several factors, including AGM and AGC CDS spreads, the U.S. dollar forward swap curve, London Interbank Offered Rate (LIBOR) curve projections, the Company's publicly traded debt and the term the securities are estimated to remain outstanding.
 
 Supplemental Executive Retirement Plans

The Company classifies the fair value measurement of the assets of the Company's various supplemental executive retirement plans as either Level 1 or Level 2. The fair value of these assets is valued based on the observable published daily values of the underlying mutual fund included in the aforementioned plans (Level 1) or based upon the NAV of the funds if a published daily value is not available (Level 2). The NAVNAV's are based on observable information.

Contracts Accounted for as Credit Derivatives
 
The Company’s credit derivatives primarily consist primarily of insured CDS contracts, and also include interest rate swaps and as of December 31, 2016, hedges on other financial guarantors that fall under derivative accounting standards requiring fair value accounting through the statement of operations. The following is a description of the fair value methodology applied to the Company's insured CDS that are accounted for as credit derivatives, which constitute the vast majority of the net credit derivative liability in the consolidated balance sheets.derivatives. The Company did not enter into CDS with the intent to trade these

contracts and the Company may not unilaterally terminate a CDS contract absent an event of default or termination event that entitles the Company to terminate such contracts; however, the Company has mutually agreed with various counterparties to terminate certain CDS transactions. Such terminationsIn transactions where the counterparty does not have the right to terminate, such transactions are generally are doneterminated for an amount that approximates the present value of future premiums or for a negotiated amount; notamount, rather than at fair value.
 
The terms of the Company’s CDS contracts differ from more standardized credit derivative contracts sold by companies outside the financial guaranty industry. The non-standard terms generally include the absence of collateral support agreements or immediate settlement provisions. In addition, the Company employs relatively high attachment points and does not exit derivatives it sells, or purchases for credit protection purposes, except under specific circumstances such as mutual agreements with counterparties. Management considers the non-standard terms of its credit derivative contracts in determining the fair value of these contracts.
 
Due to the lack of quoted prices and other observable inputs for its instruments or for similar instruments, the Company determines the fair value of its credit derivative contracts primarily through internally developed, proprietary models that use both observable and unobservable market data inputs to derive an estimate of the fair value of the Company's contracts in its principal markets (see "Assumptions and Inputs").inputs. There is no established market where financial guaranty insured credit derivatives are actively traded,traded; therefore, management has determined that the exit market for the Company’s credit derivatives is a hypothetical one based on its entry market. Management has tracked the historical pricing of the Company’s dealstransactions to establish historical price points in the hypothetical market that are used in the fair value calculation. These contracts are classified as Level 3 in the fair value hierarchy sinceas there is reliance on at least oneare multiple unobservable inputinputs deemed significant to the valuation model, most importantly the Company’s estimate of the value of the non-standard terms and conditions of its credit derivative contracts and ofhow the Company’s currentown credit standing.

The Company’s models andspread affects the related assumptions are continuously reevaluated by management and enhanced, as appropriate, based upon improvements in modeling techniques and availabilitypricing of more timely and relevant market information.its transactions.
 
The fair value of the Company’s credit derivative contracts represents the difference between the present value of remaining premiums the Company expects to receive or pay and the estimated present value of premiums that a financial guarantor of comparable credit-worthiness would hypothetically charge or pay at the reporting date for the same protection. The fair value of the Company’s credit derivatives depends on a number of factors, including notional amount of the contract, expected term, credit spreads, changes in interest rates, the credit ratings of referenced entities, the Company’s own credit risk and remaining contractual cash flows. The expected remaining contractual premium cash flows are the most readily observable inputs since they are based on the CDS contractual terms. Credit spreads capture the effect of recovery rates and performance of underlying assets of these contracts, among other factors. Consistent with previous years, market conditions at December 31, 20162018 were such that market prices of the Company’s CDS contracts were not available.
Management considers factors such as current prices charged for similar agreements, when available, performance of underlying assets, life of the instrument, and the nature and extent of activity in the financial guaranty credit derivative marketplace. The assumptions that management uses to determine the fair value may change in the future due to market conditions. Due to the inherent uncertainties of the assumptions used in the valuation models, actual experience may differ from the estimates reflected in the Company’s consolidated financial statements and the differences may be material.


Assumptions and Inputs
 
The various inputs and assumptions that are key to the establishment of the Company’s fair value for CDS contracts are as follows:
Gross spread.

The the gross spread, the allocation of gross spread among:
among the bank profit, net spread and hedge cost, and the profit the originator, usually an investment bank, realizes for putting the deal together and funding the transaction (bank profit);

premiums paid to the Company for the Company’s credit protection provided (“net spread”); and

the cost of CDS protection purchased by the originator to hedge their counterparty credit risk exposure to the Company (hedge cost).

The weighted average life which is based on debt service schedules.

The rates used to discount future expected premium cash flows ranged from 1.00% to 2.55% at December 31, 2016 and 0.44% to 2.51% at December 31, 2015.
The Company obtains gross spreads on its outstanding contracts from market data sources published by third parties (e.g., dealer spread tables for the collateral similar to assets within the Company’s transactions), as well as collateral-specific spreads provided by trustees or obtained from market sources. If observable market credit spreads are not available or reliableThe bank profit represents the profit the originator, usually an investment bank, realizes for structuring and funding the transaction; the net spread represents the premiums paid to the Company for the underlying reference obligations, thenCompany’s credit protection provided; and the hedge cost represents the cost of CDS protection purchased by the originator to hedge its counterparty credit risk exposure to the Company.

With respect to CDS transactions for which there is an expected claim payment within the next twelve months, the allocation of gross spread reflects a higher allocation to the cost of credit rather than the bank profit component. In the current market, indices are usedit is assumed that most closely resemble the underlying reference obligations, considering asset class, credit quality rating and maturity of the underlying reference obligations. These indices are adjusteda bank would be willing to reflect the non-standard terms of the Company’s CDS contracts. accept a lower profit on distressed transactions in order to remove these transactions from its financial statements.

Market sources determine credit spreads by reviewing new issuance pricing for specific asset classes and receiving price quotes from their trading desks for the specific asset in question. Management validates these quotes by cross-referencing quotes received from one market source against quotes received from another market source to ensure reasonableness. In addition, the Company compares the relative change in price quotes received from one quarter to another, with the relative change experienced by published market indices for a specific asset class. Collateral specific spreads obtained from third-party, independent market sources are un-published spread quotes from market participants or market traders who are not trustees. Management obtains this information as the result of direct communication with these sources as part of the valuation process.

With respect to CDS transactions for which there is an expected claim payment within the next twelve months, the allocation of gross spread reflects a higher allocation to the cost of credit rather than the bank profit component. In the current market, it is assumed that a bank would be willing to accept a lower profit on distressed transactions in order to remove these transactions from its financial statements.
The following spread hierarchy is utilized in determining which source of gross spread to use, with the rule being to use CDS spreads where available. If not available, CDS spreads are either interpolated or extrapolated based on similar transactions or market indices.use.

Over time the data inputs can change as new sources become available or existing sources are discontinued or are no longer considered to be the most appropriate. It is the Company’s objective to move to higher levels on the hierarchy whenever possible, but it is sometimes necessary to move to lower priority inputs because of discontinued data sources or management’s assessment that the higher priority inputs are no longer considered to be representative of market spreads for a given type of collateral. This can happen, for example, if transaction volume changes such that a previously used spread index is no longer viewed as being reflective of current market levels.

The Company interpolates a curve based on the historical relationship between therates used to discount future expected premium the Company receives when a credit derivative is closedcash flows ranged from 2.47% to the daily closing price of the market index related2.89% at December 31, 2018 and 1.72% to the specific asset class and rating of the deal. This curve indicates expected credit spreads2.55% at each indicative level on the related market index. For transactions with unique terms or characteristics where no price quotes are available, management extrapolates credit spreads based on a similar transaction for which the Company has received a spread quote from one of the first three sources within the Company’s spread hierarchy. This alternative transaction will be within the same asset class, have similar underlying assets, similar credit ratings, and similar time to maturity. The Company then calculates the percentage of relative spread change quarter over quarter for the alternative transaction. This percentage change is then applied to the historical credit spread of the transaction for which no price quote was received in order to calculate the transactions’ current spread. Counterparties determine credit spreads by reviewing new issuance pricing for specific asset classes and receiving price quotes from their trading desks for the specific asset in question. These quotes are validated by cross-referencing quotes received from one market source with those quotes received from another market source to ensure reasonableness.December 31, 2017.

The premium the Company receives is referred to as the “net spread.” The Company’s pricing model takes into account not only how credit spreads on risks that it assumes affect pricing, but also how the Company’s own credit spread affects the pricing of its deals.transactions. The Company’s own credit risk is factored into the determination of net spread based on the impact of changes in the quoted market price for credit protection bought on the Company, as reflected by quoted market

prices on CDS referencing AGC or AGM. For credit spreads on the Company’s name the Company obtains the quoted price of CDS contracts traded on AGC and AGM from market data sources published by third parties. The cost to acquire CDS protection referencing AGC or AGM affects the amount of spread on CDS dealstransactions that the Company retains and, hence, their fair value. As the cost to acquire CDS protection referencing AGC or AGM increases, the amount of premium the Company retains on a dealtransaction generally decreases. AsDue to the cost to acquirelow volume and total net par of CDS protection referencing AGC or AGM decreases,contracts remaining in AGM's portfolio, changes in AGM's credit spreads do not significantly affect the amountfair value of premium the Company retains on a deal generally increases. these CDS contracts.

In the Company’s valuation model, the premium the Company captures is not permitted to go below the minimum rate that the Company would currently charge to assume similar risks. This assumption can have the effect of mitigating the amount of unrealized gains that are recognized on certain CDS contracts. Given the current market conditions and the Company’s own credit spreads, approximately 26%17% and 20% ,16% based on number of deals,fair value, of the Company's CDS contracts arewere fair valued using this minimum premium as of December 31, 20162018 and December 31, 2015,2017, respectively. The percentage of dealstransactions that price using the minimum premiums fluctuates due to changes in AGM's and AGC's credit spreads. In general when AGM's and AGC's credit spreads narrow, the cost to hedge AGM's and AGC's name declines and more transactions price above previously established floor levels. Meanwhile, when AGM's and AGC's credit spreads widen, the cost to hedge AGM's and AGC's name increases causing more transactions to price at previously established floor levels. The Company corroborates the assumptions in its fair value model, including the portion of exposure to AGC and AGM hedged by its counterparties, with independent third parties each reporting period. The current level of AGC’s and AGM’s own credit spread has resulted in the bank or dealtransaction originator hedging a significant portion of its exposure to AGC and AGM. This reduces the amount of contractual cash flows AGC and AGM can capture as premium for selling its protection.

The amount of premium a financial guaranty insurance market participant can demand is inversely related to the cost of credit protection on the insurance company as measured by market credit spreads assuming all other assumptions remain constant. This is because the buyers of credit protection typically hedge a portion of their risk to the financial guarantor, due to the fact that the contractual terms of the Company's contracts typically do not require the posting of collateral by the guarantor. The extent of the hedge depends on the types of instruments insured and the current market conditions.
 
A fair value resulting in a credit derivative assetliability on protection sold is the result of contractual cash inflows on in-force deals in excess oftransactions that are less than what a hypothetical financial guarantor could receive if it sold protection on the same risk as of the reporting date. If the Company were able to freely exchange these contracts (i.e., assuming its contracts did not contain proscriptions on transfer and there was a viable exchange market), it would be able to realize a gainloss representing the difference between the higherlower contractual premiums to which it is entitled and the current market premiums for a similar contract. The Company determines the fair value of its CDS contracts by applying the difference between the current net spread and the contractual net spread for the remaining duration of each contract to the notional value of its CDS contracts and taking the present value of such amounts discounted at the corresponding LIBOR over the weighted average remaining life of the contract.

Example
The following is an example of how changes in gross spreads, the Company’s own credit spread and the cost to buy protection on the Company affect the amount of premium the Company can demand for its credit protection. The assumptions used in these examples are hypothetical amounts. Scenario 1 represents the market conditions in effect on the transaction date and Scenario 2 represents market conditions at a subsequent reporting date.
 Scenario 1 Scenario 2
 bps % of Total bps % of Total
Original gross spread/cash bond price (in bps)185
  
 500
  
Bank profit (in bps)115
 62% 50
 10%
Hedge cost (in bps)30
 16% 440
 88%
The premium the Company receives per annum (in bps)40
 22% 10
 2%
In Scenario 1, the gross spread is 185 basis points. The bank or deal originator captures 115 basis points of the original gross spread and hedges 10% of its exposure to AGC, when the CDS spread on AGC was 300 basis points (300 basis points × 10% = 30 basis points). Under this scenario the Company receives premium of 40 basis points, or 22% of the gross spread.
In Scenario 2, the gross spread is 500 basis points. The bank or deal originator captures 50 basis points of the original gross spread and hedges 25% of its exposure to AGC, when the CDS spread on AGC was 1,760 basis points (1,760 basis points × 25% = 440 basis points). Under this scenario the Company would receive premium of 10 basis points, or 2% of the gross spread. Due to the increased cost to hedge AGC’s name, the amount of profit the bank would expect to receive, and the premium the Company would expect to receive decline significantly.
In this example, the contractual cash flows (the Company premium received per annum above) exceed the amount a market participant would require the Company to pay in today’s market to accept its obligations under the CDS contract, thus resulting in an asset.

Strengths and Weaknesses of Model
 
The Company’s credit derivative valuation model, like any financial model, has certain strengths and weaknesses.
 
The primary strengths of the Company’s CDS modeling techniques are:
 
The model takes into account the transaction structure and the key drivers of market value. The transaction structure includes par insured, weighted average life, level of subordination and composition of collateral.

The model maximizes the use of market-driven inputs whenever they are available. The key inputs to the model are market-based spreads for the collateral, and the credit rating of referenced entities. These are viewed by the Company to be the key parameters that affect fair value of the transaction.

The model is a consistent approach to valuing positions. The Company has developed a hierarchy for market-based spread inputs that helps mitigate the degree of subjectivity during periods of high illiquidity.
 
The primary weaknesses of the Company’s CDS modeling techniques are:
 
There is no exit market or any actual exit transactions. Thereforetransactions; therefore, the Company’s exit market is a hypothetical one based on the Company’s entry market.

There is a very limited market in which to validate the reasonableness of the fair values developed by the Company’s model.

The markets for the inputs to the model wereare highly illiquid, which impacts their reliability.
 

Due to the non-standard terms under which the Company enters into derivative contracts, the fair value of its credit derivatives may not reflect the same prices observed in an actively traded market of credit derivatives that do not contain terms and conditions similar to those observed in the financial guaranty market.

These contracts were classified as Level 3 in the fair value hierarchy because there is a reliance on at least one unobservable input deemed significant to the valuation model, most significantly the Company's estimate of the value of non-standard terms and conditions of its credit derivative contracts and amount of protection purchased on AGC or AGM's name.

Fair Value Option on FG VIEs’ Assets and Liabilities
 
The Company elected the fair value option for all the FG VIEs’ assets and liabilities. See Note 9, Consolidated Variable Interest Entities.
liabilities and classifies them as Level 3 in the fair value hierarchy. The prices are generally determined with the assistance of an independent third-party, based on a discounted cash flow approach. The FG VIEs issued securities collateralized by first lien and second lien RMBS as well as loans and receivables. The lowest level input that is significant to the fair value measurement of these assets and liabilities was a Level 3 input (i.e., unobservable), therefore management classified them as Level 3 in the fair value hierarchy. Prices are generally determined with the assistance of an independent third-party, based on a discounted cash flow approach. The models to price the FG VIEs’ liabilities used, where appropriate, inputs such as estimated prepayment speeds; market values of the assets that collateralize the securities; estimated default rates (determined on the basis of an analysis of collateral attributes, historical collateral performance, borrower profiles and other features relevant to the evaluation of collateral credit quality); yields implied by market prices for similar securities; house price depreciation/appreciation rates based on macroeconomic forecasts and, for those liabilities insured by the Company, the benefit from the Company’s insurance policy guaranteeing the timely payment of principal and interest, taking into account the timing of the potential default and the Company’s own credit rating. The third-party also utilizes an internal model to determine an appropriate yield at which to discount the cash flows of the security, by factoring in collateral types, weighted-average lives, and other structural attributes specific to the security being priced. The expected yield is further calibrated by utilizing algorithms designed to aggregate market color, received by the third-party, on comparable bonds.
 
The fair value of the Company’s FG VIEVIEs’ assets is generally sensitive to changes related toin estimated prepayment speeds; estimated default rates (determined on the basis of an analysis of collateral attributes such as: historical collateral performance, borrower profiles and other features relevant to the evaluation of collateral credit quality); yields implied by market prices for similar securities; and house price depreciation/appreciation rates based on macroeconomic forecasts. Significant changes to some of these inputs could have materially changechanged the market value of the FG VIE’sVIEs’ assets and the implied collateral losses within the transaction. In general, the fair value of the FG VIE assetVIEs’ assets is most sensitive to changes in the projected collateral losses, where an increase in collateral losses typically leadscould lead to a decrease in the fair value of FG VIEVIEs’ assets, while a decrease in collateral losses typically leads to an increase in the fair value of FG VIEVIEs’ assets. These factors also directly impactThe third-party utilizes an internal model to determine an appropriate yield at which to discount the cash flows of the security, by factoring in collateral types, weighted-average lives, and other structural attributes specific to the security being priced. The expected yield is further calibrated by utilizing algorithms designed to aggregate market color, received by the independent third-party, on comparable bonds.

The models to price the FG VIEs’ liabilities used, where appropriate, the same inputs used in determining fair value of FG VIEs’ assets and, for those liabilities insured by the Company’s FG VIE liabilities.Company, the benefit from the Company's insurance policy guaranteeing the timely payment of principal and interest, taking into account the Company's own credit risk.
 
The fair value of the Company’s FG VIE liabilities is generally sensitive to the various model inputs described above. In addition, the Company’s FG VIE liabilities with recourse are also sensitive to changes in the Company’s implied credit worthiness. Significant changes to any of thesethe inputs described above could have materially changechanged the timing of expected losses within the insured transaction which is a significant factor in determining the implied benefit from the Company’s insurance policy guaranteeing the timely payment of principal and interest for the tranches of debt issued by the FG VIEVIEs that is insured by the Company. In general, extending the timing of expected loss payments by the Company into the future typically leadscould lead to a decrease in the value of the Company’s insurance and a decrease in the fair value of the Company’s FG VIEVIEs’ liabilities with recourse, while a shortening of the timing of expected loss payments by the Company typically leadscould lead to an increase in the value of the Company’s insurance and an increase in the fair value of the Company’s FG VIEVIEs’ liabilities with recourse.

Not Carried at Fair Value

Financial Guaranty Insurance Contracts

For financial guaranty insurance contracts that are acquired in a business combination, the Company measures each contract at fair value on the date of acquisition, and then follows insurance accounting guidance on a recurring basis thereafter.  On a quarterly basis,In addition, the Company also discloses the fair value of its outstanding financial guaranty insurance contracts.  In both cases, fair value is based on management’s estimate of what a similarly rated financial guaranty insurance company would demand to acquire the Company’s in-force book of financial guaranty insurance business. It is based on a variety of factors that may include pricing assumptions management has observed for portfolio transfers, commutations, and acquisitions that have occurred in the financial guaranty market, as well as prices observed in the credit derivative market with an adjustment for illiquidity so that the terms would be similar to a financial guaranty insurance contract, and also includes adjustments to the carrying value of unearned premium reserve for stressed losses, ceding commissions and return on capital. The significant inputs were not readily observable. The Company accordingly classified this fair value measurement as Level 3.

 
Long-Term Debt
 
The Company’s long-termLong-term debt excluding notes payable,issued by AGUS and AGMH is valued by broker-dealers using third party independent pricing sources and standard market conventions. The market conventions utilize market quotations, market transactions for the Company’s comparable instruments, and to a lesser extent, similar instruments in the broader insurance industry. The fair value measurement was classified as Level 2 in the fair value hierarchy.
 
The fair value of the notes payable issued by AGM was determined by calculating the present value of the expected cash flows. The fair value measurement was classified as Level 3 in the fair value hierarchy.
 
Other Invested Assets
The other invested assets not carried at fair value consist primarily of investments in a guaranteed investment contract. The fair value of the investments in the guaranteed investment contract approximated their carrying value due to their short term nature. The fair value measurement of the guaranteed investment contract was classified as Level 2 in the fair value hierarchy.
Other Assets and Other Liabilities
The Company’s other assets and other liabilities consist predominantly of accrued interest, receivables for securities sold and payables for securities purchased, the carrying values of which approximate fair value.

8.Contracts Accounted for as Credit Derivatives
 
The Company has a portfolio of financial guaranty contracts that meet the definition of a derivative in accordance with GAAP (primarily CDS). The credit derivativesderivative portfolio also includes interest rate swapsswaps.

Credit derivative transactions are governed by ISDA documentation and hedgeshave certain characteristics that differ from financial guaranty insurance contracts. For example, the Company’s control rights with respect to a reference obligation under a credit derivative may be more limited than when the Company issues a financial guaranty insurance contract. In addition, there

are more circumstances under which the Company may be obligated to make payments. Similar to a financial guaranty insurance contract, the Company would be obligated to pay if the obligor failed to make a scheduled payment of principal or interest in full. However, the Company may also be required to pay if the obligor becomes bankrupt or if the reference obligation were restructured if, after negotiation, those credit events are specified in the documentation for the credit derivative transactions. Furthermore, the Company may be required to make a payment due to an event that is unrelated to the performance of the obligation referenced in the credit derivative. If events of default or termination events specified in the credit derivative documentation were to occur, the non-defaulting or the non-affected party, which may be either the Company or the counterparty, depending upon the circumstances, may decide to terminate a credit derivative prior to maturity. In that case, the Company may be required to make a termination payment to its swap counterparty upon such termination. Absent such an event of default or termination event, the Company may not unilaterally terminate a CDS contract; however, the Company on other financial guarantors.occasion has mutually agreed with various counterparties to terminate certain CDS transactions.

Accounting Policy

Credit derivatives are recorded at fair value. Changes in fair value are recorded in “net change in fair value of credit derivatives” on the consolidated statement of operations. Realized gains (losses) and other settlements on credit derivatives include credit derivative premiums received and receivable for credit protection the Company has sold under its insured CDS contracts, premiums paid and payable for credit protection the Company has purchased, claims paid and payable and received and receivable related to insured credit events under these contracts, ceding commission expense or income and any realized gains or losses related to their earlyon termination. FairThe fair value of credit derivatives is reflected as either net assets or net liabilities determined on a contract by contract basis in the Company's consolidated balance sheets. See Note 7, Fair Value Measurement, for a discussion on the fair value methodology for credit derivatives.

Credit Derivative Net Par Outstanding by Sector
 
Credit derivative transactions are governed by ISDA documentation and have different characteristics from financial guaranty insurance contracts. For example, the Company’s control rights with respect to a reference obligation under a credit derivative may be more limited than when the Company issues a financial guaranty insurance contract. In addition, there are more circumstances under which the Company may be obligated to make payments. Similar to a financial guaranty insurance contract, the Company would be obligated to pay if the obligor failed to make a scheduled payment of principal or interest in

full. However, the Company may also be required to pay if the obligor becomes bankrupt or if the reference obligation were restructured if, after negotiation, those credit events are specified in the documentation for the credit derivative transactions. Furthermore, the Company may be required to make a payment due to an event that is unrelated to the performance of the obligation referenced in the credit derivative. If events of default or termination events specified in the credit derivative documentation were to occur, the non-defaulting or the non-affected party, which may be either the Company or the counterparty, depending upon the circumstances, may decide to terminate a credit derivative prior to maturity. In that case, the Company may be required to make a termination payment to its swap counterparty upon such termination. Absent such an event of default or termination event, the Company may not unilaterally terminate a CDS contract; however, the Company on occasion has mutually agreed with various counterparties to terminate certain CDS transactions.
     The estimated remaining weighted average life of credit derivatives was 5.3 years at December 31, 2016 and 5.4 years at December 31, 2015.     The components of the Company’s credit derivative net par outstanding are presented in the table below. The increase in credit derivative net par outstanding from year-end 2017 was a result of the June 1, 2018 SGI Transaction discussed in Note 2, Assumption of Insured Portfolio and Business Combinations. As part of that transaction, the Company reinsured SGI's insurance of credit derivatives within its portfolio, primarily infrastructure finance and regulated utility transactions, with a net par of $1.5 billion and a credit derivative liability of $68 million. The credit derivatives assumed from SGI have no expected losses. The estimated remaining weighted average life of credit derivatives was 11.6 years at December 31, 2018 and 11.7 years at December 31, 2017.

(1)    Expected recoveries were $2 million as of December 31, 2018 and $14 million as of December 31, 2017.

(1)(2)The December 31, 2016 total amount includes $1.7 billion net par outstanding of credit derivatives from CIFG Acquisition.This represents numerous transactions across various asset classes, such as health care revenue, municipal utilities and and consumer receivables.


Except for TruPS CDOs, the Company’s exposure to pooled corporate obligations is highly diversified in terms of obligors and industries. Most pooled corporate transactions are structured to limit exposure to any given obligor and industry. The majority of the Company’s pooled corporate exposure consists of CLO or synthetic pooled corporate obligations. Most of these CLOs have an average obligor size of less than 1% of the total transaction and typically restrict the maximum exposure to any one industry to approximately 10%. The Company’s exposure also benefits from embedded credit enhancement in the transactions which allows a transaction to sustain a certain level of losses in the underlying collateral, further insulating the Company from industry specific concentrations of credit risk on these deals.
The Company’s TruPS CDO asset pools are generally less diversified by obligors and industries than the typical CLO asset pool. Also, the underlying collateral in TruPS CDOs consists primarily of subordinated debt instruments such as TruPS issued by bank holding companies and similar instruments issued by insurance companies, real estate investment trusts and other real estate related issuers while CLOs typically contain primarily senior secured obligations. However, to mitigate these risks TruPS CDOs were typically structured with higher levels of embedded credit enhancement than typical CLOs.

The Company’s exposure to “Other” CDS contracts is also highly diversified. It includes $1.5 billion of exposure to one pooled infrastructure transaction comprising diversified pools of international infrastructure project transactions and loans to regulated utilities. These pools were all structured with underlying credit enhancement sufficient for the Company to attach at AAA levels at origination. The remaining $3.9 billion of exposure in “Other” CDS contracts comprises numerous deals across various asset classes, such as commercial receivables, international RMBS, infrastructure, regulated utilities and consumer receivables.

During 2016,2018, unrealized fair value gains were primarily generated primarily as a result ofby CDS terminations, in the U.S. RMBS and other sectors, run-off of CDS par and price improvements on the underlying collateral of the Company’s CDS. The majorityIn addition, unrealized fair value gains were generated by the increase in credit given to the primary insurer on one of the Company's second-to-pay CDS transactions were terminated as a result of settlement agreements with several CDS counterparties.policies during the period. The unrealized fair value gains were partially offset by unrealized fair value losses resulting from wider implied net spreads across all sectors. The wider implied net spreads were primarily a result ofdriven by the decreased cost to buy protection in AGC’s and AGM’s name, as the market cost of AGC’s and AGM’s credit protection decreased significantly during the period. TheseFor those CDS transactions that were pricing at or above their floor levels, (or the minimum rate at which the Company would consider assuming these risks based on historical experience); therefore when the cost of purchasing CDS protection on AGC and AGM, which management refers to as the CDS spread on AGC and AGM, decreased the implied spreads that the Company would expect to receive on these transactions increased.

During 2015,2017 and 2016, unrealized fair value gains were primarily generated primarilyby CDS terminations, run-off of net par outstanding, and price improvements on the underlying collateral of the Company’s CDS. The majority of the CDS transactions that were terminated were as a result of settlement agreements with several CDS terminations. The Company reached a settlement agreement with one CDS counterparty to terminate five Alt-A first lien CDS transactions resulting in unrealized fair value gains of $213 million and wascounterparties. In 2016, the primary driver of the unrealized fair value gains in the U.S. RMBS sector. The Company also terminated a CMBS transaction, a Triple-X life insurance securitization transaction, and a distressed middle market CLO securitization during the period and recognized unrealized fair value gains of $41 million, $99 million and $99 million, respectively. These were the primary drivers of the unrealized fair value gains in the CMBS, Other, and pooled corporate CLO sectors, respectively, during the period. The remainder of the fair value gains for the period were a result of tighter implied net spreads across all sectors. The tighter implied net spreads were primarily a result of the increased cost to buy protection in AGC’s and AGM’s name, particularly for the one year CDS spread. These transactions were pricing at or above their floor levels, therefore when the cost of purchasing CDS protection on AGC and AGM increased, the implied spreads that the Company would expect to receive on these transactions decreased. Finally, during 2015, there was a refinement in methodology to address an instance in a U.S. RMBS transaction where the Company now expects recoveries. This refinement resulted in approximately $49 million in fair value gains in 2015.

During 2014, unrealized fair value gains were generated primarily in the U.S. RMBS prime first lien, Option ARM and subprime sectors. This is primarily due to a significant unrealized fair value gain in the Option ARM and Alt-A first lien sector of approximately $543 million, as a result of the terminations of three large Alt-A first lien resecuritization transactions and one Option ARM first lien transaction during the period. In addition, there was an unrealized gain of approximately $346 million related to the change in index used to determine fair value during the fourth quarter of 2014. In the fourth quarter of 2014, new market indices were published on Option ARM and Alt-A first lien securitizations. As part of the Company’s normal review process the Company reviewed these indices and based upon the collateral make-up, collateral vintage, and collateral loss experience, determined it to be a better market indication for the Company’s Option ARM and Alt-A first lien securitizations. The unrealized fair value gains were partially offset by unrealized fair value losses generated byresulting from wider implied net spreads. The wider implied net spreads were primarily a result of the decreased cost to buy protection in AGC’s and AGM’s name, as the market cost of AGC'sAGC’s and AGM’s credit protection decreased significantly during the period. These transactions were pricing at or above their floor levels (or the minimum rate at which the Company would consider assuming these risks based on historical experience); therefore whenDuring 2017, the cost to buy protection in AGC’s and AGM’s name, specifically the five-year CDS spread, did not change materially during the period, and therefore did not have a material impact on the Company’s unrealized fair value gains and losses on CDS.

The impact of changes in credit spreads will vary based upon the volume, tenor, interest rates, and other market conditions at the time these fair values are determined. In addition, since each transaction has unique collateral and structural terms, the underlying change in fair value of each transaction may vary considerably. The fair value of credit derivative contracts also reflects the change in the Company’s own credit cost based on the price to purchase credit protection on AGC and AGM. The Company determines its own credit risk based on quoted CDS prices traded on the Company at each balance sheet date.

The fair value of CDS contracts at December 31, 2016,2018, before considering the implications of AGC’s and AGM’s credit spreads, is a direct result of continued wide credit spreads in the fixed income security markets and ratings downgrades. The asset classes that remain most affected are TruPS and pooled corporate securities as well as 2005-2007 vintages of Alt-A, Option ARM and subprime RMBS deals. The mark to market benefit between December 31, 2016, and December 31, 2015, resulted primarily from several CDS terminations and a narrowing of credit spreads related to the Company's TruPS and U.S. RMBS obligations.

Management believes that the trading level of AGC’s and AGM’s credit spreads over the past several years has been due to the correlation between AGC’s and AGM’s risk profile and the current risk profile of the broader financial markets, as well as the overall lack of liquidity in the CDS market. Offsetting the benefit attributable to AGC’s and AGM’s credit spread were higher credit spreads in the fixed income security markets. The higher credit spreads in the fixed income security market are due to the lack of liquidity in the high yield CDO, TruPS CDO, pooled infrastructure, and CLOinfrastructure finance markets as well as continuing market concerns over the 2005-2007 vintages of RMBS.

Ratings Sensitivities ofCollateral Posting for Certain Credit Derivative Contracts
 
Within the Company’s insured CDS portfolio, theThe transaction documentation with one counterparty for approximately $0.7 billion in$250 million of CDS gross par insured as of December 31, 2016by AGC requires AGC to post eligible collateral, subject to a $250 million cap, to secure its obligationsobligation to make payments under such contracts. This constitutes a reduction of approximately $3.1 billion from the $3.8 billion subject to such a requirement as of December 31, 2015, primarily due to an agreement reached in May 2016 with a CDS counterparty reducing the collateral posting requirement with respect to that counterparty to zero. Eligible collateral is generally cash or U.S. government or agency securities; eligible collateral other than cash is valued at a discount to the face amount.

For approximately $516 million gross par of such contracts, AGC has negotiated caps such that the The table below summarizes AGC’s CDS collateral posting requirement cannot exceed a certain fixed amount, regardless of the mark-to-market valuation of the exposure or the financial strength ratings of AGC. For such contracts, AGC need not post on a cash basis an aggregate of more than $500 million, although the value of the collateral posted may exceed such fixed amount depending on the advance rate agreed with the counterparty for the particular type of collateral posted.

For the remaining approximately $174 million gross par of such contracts, AGC could be required from time to time to post additional collateral without such cap based on movements in the mark-to-market valuation of the underlying exposure. 

Asrequirements as of December 31, 2016, the Company was posting approximately $116 million to secure its obligations under CDS, of which approximately $16 million related to the $174 million of gross par described above, as to which the obligation to collateralize is not capped. As of2018 and December 31, 2015,2017.

9.Consolidated Variable Interest Entities
 
Background

The Company provides financial guaranties with respect to debt obligations of special purpose entities, including VIEs. Assured GuarantyVIEs but does not act as the servicer or collateral manager for any VIE obligations insuredguaranteed by its companies.insurance subsidiaries. The transaction structure generally provides certain financial protections to the Company. This financial protection can take several forms, the most common of which are overcollateralization, first loss protection (or subordination) and excess spread. In the case of overcollateralization (i.e., the principal amount of the securitized assets exceeds the principal amount of the structured finance obligations guaranteed by the Company), the structure allows defaults of the securitized assets before a default is experienced on the structured finance obligation guaranteed by the Company. In the case of first loss, the Company's financial guaranty insurance policy only covers a senior layer of losses experienced by multiple obligations issued by special purpose entities, including VIEs. The first loss exposure with respect to the assets is either retained by the seller or sold off in the form of equity or mezzanine debt to other investors. In the case of excess spread, the financial assets contributed to special purpose entities, including VIEs, generate interest income that are in excess of the interest payments on the debt issued by the special purpose entity.VIE. Such excess spread is typically distributed through the transaction’s cash flow waterfall and may be used to create additional credit enhancement, applied to redeem debt issued by the special purpose entities, including VIEs (thereby, creating additional overcollateralization), or distributed to equity or other investors in the transaction.

Assured Guaranty is not primarily liable for the debt obligations issued by the VIEs it insures and would only be required to make payments on those insured debt obligations in the event that the issuer of such debt obligations defaults on any principal or interest due and only for the amount of the shortfall. AGL’s and its Subsidiaries’subsidiaries’ creditors do not have any rights with regard to the collateral supporting the debt issued by the FG VIEs. Proceeds from sales, maturities, prepayments and interest from such underlying collateral may only be used to pay debt service on VIEFG VIEs’ liabilities. Net fair value gains and losses on FG VIEs are expected to reverse to zero at maturity of the VIEFG VIEs’ debt, except for net premiums received and net claims paid by Assured Guaranty under the financial guaranty insurance contract. The Company’s estimate of expected loss to be paid for FG VIEs is included in Note 5, Expected Loss to be Paid.
 
Accounting Policy

The Company evaluates whether it is the primary beneficiary of its VIEs. If the Company concludes that it is the primary beneficiary, it is required to consolidate the entire VIE in the Company's financial statements and eliminate the effects of the financial guaranty insurance contracts issued by AGM and AGC on the consolidated FG VIEsVIEs’ debt obligations.

The primary beneficiary of a VIE is the enterprise that has both 1) the power to direct the activities of a VIE that most significantly impact the entity's economic performance; and 2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE.


As part of the terms of its financial guaranty contracts, the Company, under its insurance contract, obtains certain protective rights with respect to the VIE that give the Company additional controls over a VIE. These protective rights are triggered by the occurrence of certain events, such as failure to be in compliance with a covenant due to poor deal performance or a deterioration in a servicer or collateral manager's financial condition. At deal inception, the Company typically is not deemed to control a VIE; however, once a trigger event occurs, the Company's control of the VIE typically increases. The Company continuously evaluates its power to direct the activities that most significantly impact the economic performance of VIEs that have debt obligations insured by the Company and, accordingly, where the Company is obligated to absorb VIE losses or receive benefits that could potentially be significant to the VIE. The Company obtains protective rights under its insurance contracts that give the Company additional controls over a VIE if there is either deterioration of deal performance or in the financial health of the deal servicer. The Company is deemed to be the control party for certain VIEs under GAAP, typically when its protective rights give it the power to both terminate and replace the deal servicer, which are characteristics specific to the Company's financial guaranty contracts. If the protective rights that could make the Company the control party have not been triggered, then the VIE is not consolidated. If the Company is deemed no longer to have those protective rights, the transactionVIE is deconsolidated.

The FG VIEs'VIEs’ liabilities that are insured by the Company are considered to be with recourse, because the Company guarantees the payment of principal and interest regardless of the performance of the related FG VIEs'VIEs’ assets. FG VIEs'VIEs’ liabilities that are not insured by the Company are considered to be without recourse, because the payment of principal and interest of these liabilities is wholly dependent on the performance of the FG VIEs'VIEs’ assets.


The Company has limited contractual rights to obtain the financial records of its consolidated FG VIEs. The FG VIEs do not prepare separate GAAP financial statements; therefore, the Company compiles GAAP financial information for them based on trustee reports prepared by and received from third parties. Such trustee reports are not available to the Company until approximately 30 days after the end of any given period. The time required to perform adequate reconciliations and analyses of the information in these trustee reports results in a one quarter lag in reporting the FG VIEs'VIEs’ activities. The Company records the fair value of FG VIEVIEs’ assets and liabilities based on modeled prices. The Company updates the model assumptions each reporting period for the most recent available information, which incorporates the impact of material events that may have occurred since the quarter lag date. The net change in the fair value of consolidated FG VIEVIEs’ assets and liabilities is recorded in "fair value gains (losses) on FG VIEs" in the consolidated statements of operations.operations, except for change in fair value of FG VIEs’ liabilities with recourse caused by changes in ISCR which is now separately presented in OCI, effective January 1, 2018 as described below. Interest income and interest expense are derived from the trustee reports and also included in “fair"fair value gains (losses) on FG VIEs." The Company has elected the fair value option for assets and liabilities classified as FG VIEs'VIEs’ assets and liabilities because the carrying amount transition method was not practical.

The cash flows generated by the FG VIEVIEs’ assets including R&W recoveries, are classified as cash flows from investing activities. Paydowns of FG liabilities are supported by the cash flows generated by FG VIEVIEs’ assets, and for liabilities with recourse, possibly claim payments made by AGM or AGC under its financial guaranty insurance contracts. Paydowns of FG liabilities both with and without recourse are classified as cash flows used in financing activities by the Company.activities. Interest income, interest expense and other expenses of the FG VIEVIEs’ assets and liabilities are classified as operating cash flows. Claim payments made by AGC and AGM under the financial guaranty contracts issued to the FG VIEs are eliminated upon consolidation and therefore such claim payments are treated as paydowns of FG VIEVIEs’ liabilities as a financing activity as opposed to an operating activity of AGM and AGC.

Adoption of ASU 2016-01

Amendments under ASU 2016-01 apply to the Company's FG VIEs’ liabilities which the Company had historically elected to measure through the consolidated statements of operations in "fair value gains (losses) on FG VIEs" under the fair value option. For FG VIEs’ liabilities with recourse, the portion of the change in fair value caused by changes in ISCR must now be separately presented in OCI as opposed to the consolidated statements of operations.

The inception to date change in fair value of the FG VIEs’ liabilities with recourse attributable to the ISCR is calculated by holding all current period assumptions constant for each security and isolating the effect of the change in the Company’s CDS spread from the most recent date of consolidation to the current period. In general, if the Company’s CDS spread tightens, more value will be assigned to the Company’s credit; however, if the Company’s CDS widens, less value is assigned to the Company’s credit.

On adoption of ASU 2016-01, the Company reclassified a loss of approximately $33 million, net of tax, from retained earnings to AOCI. This amount represents the portion of the fair value of the FG VIEs’ liabilities with recourse that related to the change in the Company's own credit risk from the date of consolidation through January 1, 2018. The accounting and disclosure of the FG VIEs’ liabilities without recourse are unchanged.

The total unpaid principal balance for the FG VIEs’ assets that were over 90 days or more past due was approximately $137$71 million at December 31, 20162018 and $154$99 million at December 31, 2015.2017. The aggregate unpaid principal of the FG VIEs’ assets was approximately $432$350 million greater than the aggregate fair value at December 31, 2016.2018.

To calculate ISCR, the instrument specific credit risk, the changeschange in the fair value of the FG VIEVIEs’ assets areis allocated between changes that are due to the instrument specific credit riskISCR and changes due to other factors, including interest rates. The instrument specific credit riskISCR amount is determined by using expected contractual cash flows versusat the date of consolidation less current expected cash flows discounted at original contractual rate. The net present value is calculated by discounting the expected cash flows of the underlying security, at the relevant effective interest rate.

The unpaid principal for FG VIEVIEs’ liabilities with recourse, which represent obligations insured by AGC or AGM, was $871$565 million and $1,436$674 million as of December 31, 20162018 and December 31, 2015,2017, respectively. FG VIEVIEs’ liabilities with recourse will mature at various dates ranging from 20252018 to 2038. The aggregate unpaid principal balance of the FG VIE

VIEs’ liabilities with and without recourse was approximately $109$48 million greater than the aggregate fair value of the FG VIEs’ liabilities with recourse as of both December 31, 2016.2018 and December 31, 2017. The aggregate unpaid principal balance of the FG VIEs’ liabilities without recourse was approximately $423$28 million and $25 million greater than the aggregate fair value of the FG VIEs’ liabilities without recourse as of December 31, 2015.2018 and December 31, 2017, respectively. See Consolidated Statements of Comprehensive Income and Note 20, Other Comprehensive Income, for information on changes in fair value of the FG VIEs’ liabilities with recourse that is attributable to changes in the Company's own credit risk.

     The consolidationeffects of consolidating FG VIEs affects net income and shareholders' equity due toincludes (i) changes in fair value gains (losses) on FG VIEVIEs’ assets and liabilities, (ii) the elimination of premiums and losses related to the AGC and AGM FG VIEVIEs’ liabilities with recourse and (iii) the elimination of investment balances related to the Company’s purchase of AGC and AGM insured FG VIEVIEs’ debt. Upon consolidation of a FG VIE, the related insurance and, if applicable, the related investment balances, are considered intercompany transactions and therefore eliminated. Such eliminations are included in the table below to present the full effect of consolidating FG VIEs.

Fair value gains (losses) on FG VIEs represent
For all periods presented, the net change in fair value on the consolidated FG VIEs’ assets and liabilities. In 2016, the Company recorded a pre-tax net fair value gain on consolidated FG VIEs of $38 million. The primary driver of the 2016 gain in fair value of FG VIEVIEs’ assets and FG VIEs’ liabilities was net mark-to-market gains due to price appreciationan increase in the value of the FG VIEs’ assets resulting from improvementsimprovement in the underlying collateral of HELOC RMBS assets of the FG VIEs. collateral.

In 2015, the Company recorded a pre-tax net fair value gain on consolidated FG VIEs of $38 million which was primarily driven by price appreciation on the Company's FG VIE assets during the year that resulted from improvements in the underlying collateral, as well as large principal paydowns made on the Company's FG VIEs.

In 2014, the Company recorded a pre-tax net fair value gain on consolidated FG VIEs of $255 million. The primary driver of this gain, $120 million, was a result of the deconsolidation of seven VIEs. There was an additional gain of $37 million resulting from the Company exercising its option to accelerate two second lien RMBS VIEs. These two VIEs were treated as maturities during the period. The remainder of the gain for the period was driven by the price appreciation on the Company's FG VIE assets during the year resulting from improvements in the underlying collateral, as well as large principal paydowns made on the Company's FG VIEs.

Other Consolidated VIEs

In certain instances where the Company consolidates a VIE that was established as part of a loss mitigation negotiated settlement agreement that results in the termination of the original insured financial guaranty insurance or credit derivative contract, the Company classifies the assets and liabilities of those VIEs in the line items that most accurately reflect the nature of the items, as opposed to within the FG VIEVIEs’ assets and FG VIEVIEs’ liabilities. The largest of these VIEs had assets of $87 million and liabilities of $21 million as of December 31, 2018 and assets of $86 million and liabilities of $41 million as of December 31, 2017.

Non-Consolidated VIEs
 
As described in Note 4, Outstanding Exposure, the Company monitors all policies in the insured portfolio. Of the approximately 19 thousand policies monitored as of December 31, 20162018, approximately 16 thousand policies are not within the scope of ASC 810 because these financial guaranties relate to the debt obligations of governmental organizations or financing entities established by a governmental organization. The majority of the remaining policies involve transactions where the Company is not deemed to currently have control over the FG VIEs’ most significant activities. As of December 31, 2018 and 2017, the Company identified 110 and 99 policies, respectively, that contain provisions and experienced events that may trigger consolidation. Based on management’s assessment of these potential triggers or events, the Company consolidated 31 and 32 FG VIEs as of December 31, 2018 and December 31, 2015, the Company had financial guaranty contracts outstanding for approximately 600 and 750 VIEs, respectively, that it did not consolidate. To date, the Company’s analyses have indicated that it does not have indicated that it is not the primary beneficiary of any other VIEs and, as a result, they are not consolidated.2017, respectively. The Company’s exposure provided through its financial guaranties with respect to debt obligations of special purpose entitiesFG VIEs is included within net par outstanding in Note 4, Outstanding Exposure.


10.Investments and Cash
 
Accounting Policy

The vast majority of the Company's investment portfolio is composedconsists of fixed-maturity and short-term investments, classified as available-for-sale at the time of purchase (approximately 98.5%99.5% based on fair value as of December 31, 20162018), and therefore carried at fair value. Changes in fair value for other-than-temporarily-impaired (OTTI) securities are bifurcated between credit losses and non-credit changes in fair value. The credit loss on OTTIother-than-temporarily-impaired securities is recorded in the statement of operations and the non-credit component of the change in fair value of securities whether OTTI or not, is recorded in OCI. For securities in an unrealized loss position where the Company has the intent to sell or it is more-likely-than-not that it will be required to sell the security before recovery, the entire impairment loss (i.e., the difference between the security's fair value and its amortized cost) is recorded in the consolidated statements of operations.

Credit losses reduce the amortized cost of impaired securities. The amortized cost basis is adjusted for accretion and amortization (using the effective interest method) with a corresponding entry recorded in net investment income.

Realized gains and losses on sales of investments are determined using the specific identification method. Realized loss includes amounts recorded for other-than-temporary impairments (OTTI) on debt securities and the declines in fair value of securities for which the Company has the intent to sell the security or inability to hold until recovery of amortized cost.

For mortgage‑backed securities, and any other holdings for which there is prepayment risk, prepayment assumptions are evaluated and revised as necessary. Any necessary adjustments due to changes in effective yields and maturities are recognized in net investment income using the retrospective method.

Loss mitigation securities are generally purchased at a discount and are accounted for based on their underlying investment type, excluding the effects of the Company’s insurance. Interest income on loss mitigation securities is recognized on a level yield basis over the remaining life of the security.

Short-term investments, which are those investments with a maturity of less than one year at time of purchase, are carried at fair value and include amounts deposited in money market funds.

Other invested assets, as of December 31, 2018, primarily include guaranteedan investment contracts,in the limited partnership interest of a fund that invests in the equity of private equity managers and a minority interest in an independent investment advisory firm specializing in separately managed accounts, both of which are carried at amortized cost plus accrued interest and preferred stocks, which are carried at fair value with changes in unrealized gains and losses recorded in OCI.accounted for under the equity method. See "Adoption of ASU 2016-01" below.

Cash consists of cash on hand and demand deposits. As a result of the lag in reporting FG VIEs, cash and short-term investments do not reflect cash outflow to the holders of the debt issued by the FG VIEs for claim payments made by the Company's insurance subsidiaries to the consolidated FG VIEs until the subsequent reporting period.

Assessment for Other-Than Temporary Impairments

If an entity does not intend to sell the security and it is not more-likely-than-not that the Company will be required to sell the security before recovery of its amortized cost basis, the other-than-temporary-impairment is separated into (1) the amount representing the credit loss and (2) the amount related to all other factors.

The Company has a formal review process to determine other-than-temporary-impairmentOTTI for securities in its investment portfolio where there is no intent to sell and it is not more-likely-than-not that it will be required to sell the security before recovery. Factors considered when assessing impairment include:

a decline in the market value of a security by 20% or more below amortized cost for a continuous period of at least six months;

a decline in the market value of a security for a continuous period of 12 months;

recent credit downgrades of the applicable security or the issuer by rating agencies;

the financial condition of the applicable issuer;

whether loss of investment principal is anticipated;

the impact of foreign exchange rates; and

whether scheduled interest payments are past due.

The Company assesses the ability to recover the amortized cost by comparing the net present value of projected future cash flows with the amortized cost of the security. If the security is in an unrealized loss position and its net present value is less than the amortized cost of the investment, an other-than-temporary impairmentOTTI is recorded. The net present value is calculated by discounting the Company's estimate of projected future cash flows at the effective interest rate implicit in the debt security at the time of purchase. The Company's estimates of projected future cash flows are driven by assumptions regarding probability of default and estimates regarding timing and amount of recoveries associated with a default. The Company develops these estimates using information based on historical experience, credit analysis and market observable data, such as industry analyst reports and forecasts, sector credit ratings and other relevant data. For mortgage‑backed and asset backed securities, cash flow estimates also include prepayment and other assumptions regarding the underlying collateral includingsuch as default rates, recoveries and changes in value. The assumptions used in these projections requiresrequire the use of significant management judgment.

The Company's assessment of a decline in value included management's current assessment ofIn addition to the factors noted above. Theabove, the Company also seeks advice from its outside investment managers. If that assessment changes in the future, the Company may ultimately record a loss after having originally concluded that the decline in value was temporary.

Adoption of ASU 2016-01

Up until December 31, 2017, the change in fair value of preferred stock investments and certain other equity investments was recorded in OCI. Effective January 1, 2018, in accordance with ASU 2016-01, the change in fair value of these investments is recorded in other income in the consolidated statements of operations. Upon adoption of this section of ASU 2016-01, the Company reclassified a loss of approximately $1 million, net of tax, from AOCI to retained earnings. See also Note 9, Variable Interest Entities, for the effect of this ASU on FG VIEs.

In addition, in accordance with ASU 2016-01, the Company elected the new measurement alternative for equity securities that were accounted for under the cost method as of December 31, 2017 because they did not have a readily determinable fair value. Effective January 1, 2018, these equity securities are accounted at cost less any impairment, plus or minus the change resulting from observable price changes in orderly transactions for identical or a similar investment of the same issuer in the consolidated statements of operations.

Net Investment Income and Realized Gains (Losses)

Net investment income is a function of the yield that the Company earns on invested assets and the size of the portfolio. The investment yield is a function of market interest rates at the time of investment as well as the type, credit quality and maturity of the invested assets. Accrued investment income, which is recorded in Other Assets, was $91 million and $99$97 million as of December 31, 20162018 and December 31, 20152017, respectively.

(2)Net OTTI recognized in net income (loss) was primarily a result of a decline in expected cash flows on loss mitigation securities.
The proceeds from sales of fixed-maturity securities available-for-sale were $1,180 million, $1,701 million and $1,365 million for the years ended December 31, 2018, 2017 and 2016, respectively.

The Company recorded a gain on change in fair value of equity securities in other income of $27 million for the year ended December 31, 2018, which includes a gain of $31 million related to the Company's minority interest in the parent company of TMC Bonds LLC, which it sold in 2018.

Investment Portfolio

As of December 31, 2018, the majority of the investment portfolio is managed by seven outside managers (including Wasmer, Schroeder & Company LLC, in which the Company has a minority interest). The Company has established detailed guidelines regarding credit quality, exposure to a particular sector and exposure to a particular obligor within a sector. The Company's investment guidelines generally do not permit its outside managers to purchase securities rated lower than A- by S&P or A3 by Moody’s, excluding an allocation not to exceed 5% of the aggregate externally managed portfolio, to corporate securities not rated lower than BBB by S&P or Baa2 by Moody’s.

The investment portfolio tables shown below include assets managed both externally and internally. The internally managed portfolio primarily consists of the Company's investments in securities for (i) loss mitigation purposes, (ii) other risk management purposes and (iii) other alternative investments that the Company believes present an attractive investment opportunity. One of the Company's strategies for mitigating losses has been to purchase loss mitigation securities, at discounted prices. The Company also holds other invested assets that were obtained or purchased as part of negotiated settlements with insured counterparties or under the terms of the financial guaranties (other risk management assets).

Alternative investments include various funds investing in both equity and debt securities, including catastrophe bonds (until redemption in 2018) as well as investments in investment managers. In February 2017 the Company agreed to purchase up to $100 million of limited partnership interests in a fund that invests in the equity of private equity managers of which $83 million remains to be invested as of December 31, 2018.

The number of securities does not add across because lots consisting of the same securities have been purchased at different times and appear in both categories above (i.e., less than 12 months and 12 months or more). If a security appears in both categories, it is counted only once in the total column.
Of the securities in an unrealized loss position for 12 months or more as of December 31, 2018, 38 securities had unrealized losses greater than 10% of book value. The total unrealized loss for these securities as of December 31, 2018 was $43 million. As of December 31, 2017, of the securities in an unrealized loss position for 12 months or more, 28 securities had unrealized losses greater than 10% of book value with an unrealized loss of $27 million. The Company considered the credit quality, cash flows, interest rate movements, ability to hold a security to recovery and intent to sell a security in determining whether a security had a credit loss. The Company has determined that the unrealized losses recorded as of December 31, 2018 and December 31, 2017 were yield-related and not the result of OTTI.
The amortized cost and estimated fair value of available-for-sale fixed-maturity securities by contractual maturity as of December 31, 2018 are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Basis of Regulatory Financial Reporting

United States

Each of the Company's U.S. domiciled insurance companies' ability to pay dividends depends, among other things, upon theirits financial condition, results of operations, cash requirements, compliance with rating agency requirements, and is also subject to restrictions contained in the insurance laws and related regulations of theirits state of domicile and other states. Financial statements prepared in accordance with accounting practices prescribed or permitted by local insurance regulatory authorities differ in certain respects from GAAP.

The Company's U.S. domiciled insurance companies prepare statutory financial statements in accordance with accounting practices prescribed or permitted by the National Association of Insurance Commissioners (NAIC) and their respective insurance departments. Prescribed statutory accounting practices are set forth in the NAICNational Association of Insurance Commissioners Accounting Practices and Procedures Manual. The Company has no permitted accounting practices on a statutory basis, except for those related to CIFGNA which was merged into AGC in 2016 and therefore subject to statutory merger accounting requiring the restatement of prior year balances of AGC to include CIFGNA. On the CIFG Acquisition Date, accounting policies were conformed with AGC's accounting policies which do not include any permitted practices.

GAAP differs in certain significant respects from U.S. insurance companies' statutory accounting practices prescribed or permitted by insurance regulatory authorities. The principal differences result from the following statutory accounting practices:practices listed below.

upfrontUpfront premiums are earned when related principal and interest have expiredupon expiration of risk rather than earned over the expected period of coverage;coverage. Premiums earnings are accelerated when transactions are economically defeased, rather than legally defeased.

acquisitionAcquisition costs are charged to expense as incurred rather than over the period that related premiums are earned;earned.

aA contingency reserve is computed based on statutory requirements, whereas no such reserve is required under GAAP;GAAP.

certainCertain assets designated as “non-admitted assets” are charged directly to statutory surplus, rather than reflected as assets under GAAP;GAAP.

investmentsInvestments in subsidiaries are carried on the balance sheet on the equity basis, to the extent admissible, rather than consolidated with the parent;parent.

theThe amount of deferred tax assets that may be admitted is subject to an adjusted surplus threshold and is generally limited to the lesser of those assets the Company expects to realize within three years of the balance sheet date or fifteen percent of the Company's adjusted surplus. This realization period and surplus percentage is subject to change based on the amount of adjusted surplus. Under GAAP there is no non-admitted asset determination, rather a valuation allowance is recorded to reduce the deferred tax asset to an amount that is more likely than not to be realized;realized.

insuredInsured credit derivatives are accounted for as insurance contracts rather than as derivative contracts measured at fair value;value.

bondsBonds are generally carried at amortized cost rather than fair value;value.

insuredInsured obligations of VIEs and refinancing vehicles debt, where the Company is deemed the primary beneficiary, are accounted for as insurance contracts. Under GAAP, such VIEs and refinancing vehicles are consolidated and any transactions with the Company are eliminated;eliminated.

surplusSurplus notes are recognized as surplus and each payment of principal and interest is recorded only upon approval of the insurance regulator rather than as liabilities with periodic accrual of interest;interest.

push-down acquisition accounting is not applicableAcquisitions are accounted for as either statutory purchases or statutory mergers, rather than under statutory accounting practices, as it isthe purchase method under GAAP;GAAP.

losses
Losses are discounted at a rate of 4.0% or 5.0%,tax equivalent yields, and recorded when the loss is deemed probable and without consideration of the deferred premium revenue. Under GAAP, expected losses are discounted at the risk free rate at the end of each reporting period and are recorded only to the extent they exceed deferred premium revenue;revenue.


theThe present value of installment premiums and commissions are not recorded on the balance sheet as they are under GAAP; andGAAP.

mergersMergers of acquired companies are treated as statutory mergers at historical balances and financial statements are retroactively revised assuming the merger occurred at the beginning of the prior year, rather than prospectively beginning with the date of acquisition at fair value under GAAP.

Bermuda

AG Re, a Bermuda regulated Class 3B insurer, prepares itsand AGRO, a Bermuda regulated Class 3A and Class C insurer,
prepare their statutory financial statements in conformity with the accounting principles set forth in the Insurance Act 1978, amendments thereto and related regulations. As of December 31, 2016, the Bermuda Monetary Authority (Authority) now(the Authority) requires insurers to prepare statutory financial statements in accordance with the particular accounting principles adopted by the insurer (which, in the case of AG Re and AGRO, are U.S. GAAP), subject to certain adjustments. The principal difference relates to certain assets designated as “non-admitted assets” which are charged directly to statutory surplus rather than reflected as assets as they are under U.S. GAAP.

(1)Policyholders' surplus of AGM and AGC include their indirect share of MAC. AGM and AGC own approximately 61% and 39%, respectively, of the outstanding stock of Municipal Assurance Holdings Inc. (MAC Holdings), which owns 100% of the outstanding common stock of MAC.

(2)As indicated in Note 2, Acquisitions, AGC completed the acquisition of CIFGH (the parent company of CIFGNA) on July 1, 2016 and Radian Asset on April 1, 2015. Both CIFGNA and Radian Asset was merged with and into AGC, with AGC as the surviving company of the merger. The impact to AGC's policyholders' surplus was approximately $287 million from the CIFGH acquisition, on a statutory basis, as of July 1, 2016 and $333 million from the Radian Asset acquisition, on a statutory basis, as of April 1, 2015.

Contingency Reserves

On July 15, 2013, AGMAGE prepares its Solvency and its wholly-owned subsidiaryFinancial Condition Report and other required regulatory financial report based on Prudential Regulation Authority and Solvency II Regulations (Solvency II). AGE (together,adopted the AGM Group) and AGC, were notified thatfull framework required by Solvency II on January 1, 2016, which is the New York State Department of Financial Services (NYDFS) and the Maryland Insurance Administration (MIA) did not object to the AGM Group and AGC, respectively, reassuming all of the outstanding contingency reserves that the AGM Group and AGC had ceded to AG Re and electing to cease ceding future contingency reserves to AG Re. The insurance regulators permitted the AGM Group and AGC to reassume the contingency reserves in increments over three years. In the third quarter of 2015, the AGM Group and AGC each reassumed their respective final installments and asdate they became effective. As of December 31, 2015, the AGM Group2018 and AGC had collectively reassumed an aggregate of approximately $522 million.December 31, 2017, AGE's Own Funds were £693 million and £629 million, respectively.

From time to time, AGM and AGC have obtained the approval of their regulators to release contingency reserves based on losses or because the accumulated reserve is deemed excessive in relation to the insurer's outstanding insured obligations.  In 2016, on the latter basis, AGM obtained the NYDFS's approval for a contingency reserve release of approximately $175 million and AGC obtained the MIA's approval for a contingency reserve release of approximately $152 million. In addition, MAC also released approximately $53 million of contingency reserves, which consisted of the assumed contingency reserves maintained by MAC, as reinsurer of AGM, in respect of the same obligations that were the subject of AGM's $175 million release.


With respect to the regular, quarterly contributions to contingency reserves required by the applicable Maryland and New York laws and regulations, such laws and regulations permit the discontinuation of such quarterly contributions to a company’s contingency reserves when such company’s aggregate contingency reserves for a particular line of business (i.e., municipal or non-municipal) exceed the sum of the company’s outstanding principal for each specified category of obligations within the particular line of business multiplied by the specified contingency reserve factor for each such category.  In accordance with such laws and regulations, and with the approval of the MIA and the NYDFS, respectively, AGC ceased making quarterly contributions to its contingency reserves for both municipal and non-municipal business and AGM ceased making quarterly contributions to its contingency reserves for non-municipal business, in each case beginning in the fourth quarter of 2014. Such cessations are expected to continue for as long as AGC and AGM satisfy the foregoing condition for their applicable lines of business.

Dividend Restrictions and Capital Requirements

United States

Under New York insurance law, AGM and MAC may only pay dividends out of "earned surplus," which is the portion of the company's surplus that represents the net earnings, gains or profits (after deduction of all losses) that have not been distributed to shareholders as dividends, transferred to stated capital or capital surplus, or applied to other purposes permitted by law, but does not include unrealized appreciation of assets. AGM and MAC may each pay dividends without the prior approval of the New York Superintendent of Financial Services (New York Superintendent) that, together with all dividends declared or distributed by it during the preceding 12 months, do not exceed the lesser of 10% of its policyholders' surplus (as of its last annual or quarterly statement filed with the New York Superintendent) or 100% of its adjusted net investment income during that period.

The maximum amount available during 20172019 for AGM to distribute to AGMH as dividends without regulatory approval is estimated to be approximately $232$172 million. Of such $172 million, of which approximately $81$74 million is estimated to be available for distribution in the first quarter of 2017.2019. The maximum amount available during 20172019 for MAC to distribute as dividends to MAC Holdings, which is owned by AGM and AGC, without regulatory approval is estimated to be approximately $49 million.  Since its capitalization$32 million, of which approximately $5 million is available for distribution in 2013, MAC has not distributed any dividends. MAC currently intends to allocate the distributionfirst quarter of such amount quarterly in 2017.2019.
 
Under Maryland's insurance law, AGC may, with prior notice to the Maryland Insurance Commissioner, pay an ordinary dividend that, together with all dividends paid in the prior 12 months, does not exceed the lesser of 10% of its policyholders' surplus (as of the prior December 31) or 100% of its adjusted net investment income during that period. The maximum amount available during 20172019 for AGC to distribute as ordinary dividends is approximately $107$123 million. Of such $123 million, of which approximately $29$42 million is available for distribution in the first quarter of 2017.2019.

On June 30, 2016, MAC obtained approval from the NYDFS to repay its $300 million surplus note to MAC Holdings and its $100 million surplus note (plus accrued interest) to AGM. Accordingly, on June 30, 2016, MAC transferred cash and/or marketable securities to (i) MAC Holdings in an aggregate amount equal to $300 million, and (ii)  AGM in an aggregate amount of $102.5 million. MAC Holdings, upon receipt of such $300 million from MAC, distributed cash and/or marketable securities in an aggregate amount of $300 million to its shareholders, AGM and AGC, in proportion to their respective 61% and 39% ownership interests such that AGM received $182 million and AGC received $118 million.Bermuda

For AG Re, any distribution (including repurchase of shares) of any share capital, contributed surplus or other statutory capital that would reduce its total statutory capital by 15% or more of its total statutory capital as set out in its previous year's financial statements requires the prior approval of the Bermuda Monetary Authority (Authority).Authority. Separately, dividends are paid out of an insurer's statutory surplus and cannot exceed that surplus. Further,Furthermore, annual dividends cannot exceed 25% of total statutory

capital and surplus as set out in its previous year's financial statements, which is $314$312 million, without AG Re certifying to the Authority that it will continue to meet required margins. As of December 31, 2016, the Authority now requires insurers to prepare statutory financial statements in accordance with the particular accounting principles adopted by the insurer (which, in the case of AG Re, are U.S. GAAP), subject to certain adjustments. As a result of this new requirement, certain assets previously non-admitted by AG Re are now admitted, resulting in an increase to AG Re’s statutory capital and surplus limitation. Based on the foregoing limitations, in 20172019 AG Re has the capacity to (i) make capital distributions in an aggregate amount up to $128 million without the prior approval of the Authority and (ii) declare and pay dividends in an aggregate amount up to the limit of its outstanding statutory surplus, which was approximately $314$312 million as of December 31, 2016.2018. Such dividend capacity iscan be further limited by the actual amount of AG Re’s unencumbered assets, which amount changes from time to time due in part due to collateral posting requirements. As of December 31, 2016,2018, AG Re had unencumbered assets of approximately $596$416 million.

For AGRO, annual dividends cannot exceed $96 million, without AGRO certifying to the Authority that it will continue to meet required margins. Based on the foregoing limitations, in 2019 AGRO has the capacity to (i) make capital distributions in an aggregate amount up to $21 million without the prior approval of the Authority and (ii) declare and pay dividends in an aggregate amount up to approximately $96 million as of December 31, 2018. Such dividend capacity can be further limited by the actual amount of AGRO’s unencumbered assets, which were approximately $342 million as of December 31, 2018.

United Kingdom

U.K. company law prohibits each of AGE and AGUK from declaring a dividend to its shareholders unless it has “profits available for distribution.” The determination of whether a company has profits available for distribution is based on its accumulated realized profits less its accumulated realized losses. While the U.K. insurance regulatory laws impose no statutory restrictions on a general insurer's ability to declare a dividend, the Prudential Regulation Authority'sPRA's capital requirements may in practice act as a restriction on dividends.

AGM implemented the stock redemption plan in December 2016. Each share repurchased by AGM was retired and ceased to be an authorized share. Pursuant to AGM's Amended and Restated Charter, the par value of AGM's remaining shares of common stock issued and outstanding increased automatically in order to maintain AGM's total paid-in capital at $15 million and its authorized capital at $20 million.

12.Income Taxes

Accounting Policy

The provision for income taxes consists of an amount for taxes currently payable and an amount for deferred taxes. Deferred income taxes are provided for temporary differences between the financial statement carrying amounts and tax bases of assets and liabilities, using enacted rates in effect for the year in which the differences are expected to reverse. A valuation allowance is recorded to reduce the deferred tax asset to an amount that is more likely than not to be realized.

Non-interest-bearing tax and loss bonds are purchased in the amount of the tax benefit that results from deducting contingency reserves as provided under Internal Revenue Code Section 832(e). The Company records the purchase of tax and loss bonds in deferred taxes.

The Company recognizes tax benefits only if a tax position is “more likely than not” to prevail.

The Company elected to account for tax associated with Global Intangible Low-Taxed Income (GILTI) as a current-period expense when incurred.

Overview
 
AGL and its "Bermuda Subsidiaries," which consist ofBermuda subsidiaries AG Re, AGRO, and Cedar Personnel Ltd. (Bermuda Subsidiaries), are not subject to any income, withholding or capital gains taxes under current Bermuda law. The Company has received an assurance from the Minister of Finance in Bermuda that, in the event of any taxes being imposed, AGL and its Bermuda Subsidiaries will be exempt from taxation in Bermuda until March 31, 2035. AGL's U.S. and U.K. subsidiaries are subject to income taxes imposed by U.S. and U.K. authorities, respectively, and file applicable tax returns. In addition, AGRO, a Bermuda domiciled company, and AGE, a U.K. domiciled company, havehas elected under Section 953(d) of the U.S. Internal Revenue Code (the Code) to be taxed as a U.S. domestic corporation.
 

In November 2013, AGL became tax resident in the U.K. although it will remainremains a Bermuda-based company and its administrative and head office functions will continue to be carried on in Bermuda. As a U.K. tax resident company, AGL is required to file a corporation tax return with Her Majesty’s Revenue & Customs (HMRC).Customs. AGL is subject to U.K. corporation tax in respect of its worldwide profits (both income and capital gains), subject to any applicable exemptions. The main rate of corporation tax remainsrate is at 20%19% for 2016. AGL has also registered in the U.K. to report its Value Added Tax (VAT) liability.  The current rate of VAT is 20%.2018. Assured Guaranty expects that the dividends AGL receives from its direct subsidiaries will be exempt from U.K. corporation tax due to the exemption in section 931D of the U.K. Corporation Tax Act 2009. In addition, any dividends paid by AGL to its shareholders should not be subject to any withholding tax in the U.K. Assured Guaranty does not expect any profits of non-U.K. resident members of the group to be taxed under the U.K. "controlled foreign companies" regime and has obtained a clearance from HMRCHer Majesty’s Revenue & Customs confirming this on the basis of current facts.

AGUS files a consolidated federal income tax return with AGC, AG Financial Products Inc. (AGFP), AG Analytics Inc., AGMH andall of its U.S. subsidiaries. AGE, the Company’s U.K. subsidiary, had previously elected under U.S. Internal Revenue Code Section 953(d) to be taxed as a U.S. company. In January 2017, AGE filed a request with the U.S. Internal Revenue Service (IRS) to revoke the election, which was approved in May 2017. As a result of the revocation of the Section 953(d) election, AGE is no longer liable to pay future U.S. taxes beginning in 2017.

On April 1, 2015January 10, 2017, AGC purchased Radian Asset and Van American. Subsequent toMBIA UK, a U.K. based insurance company. After the purchase, Radian Asset merged into AGCMBIA UK changed its name to AGLN and dissolved. Van American joined AGUS consolidatedfiles its tax group.

Assured Guaranty Overseas U.S.US Holdings Inc. and its subsidiaries AGRO and AG Intermediary Inc., file their own consolidated federal income tax return.

Effect of the 2017 Tax Cuts and Jobs Act

On December 22, 2017, the 2017 Tax Cuts and Jobs Act (Tax Act) was signed into law. The Tax Act changed many items of U.S. corporate income taxation, including a reduction of the corporate income tax rate from 35% to 21%, implementation of a territorial tax system and imposition of a tax on deemed repatriated earnings of non-U.S. subsidiaries. At December 31, 2017, the Company had not completed accounting for the tax effects of the Tax Act; however, the Company made a reasonable estimate of the effects on the existing deferred tax balances and the one-time transition tax. The Company recognized a provisional income tax expense of $61 million, which was included as a component of income tax expense from continuing operations in 2017. During 2018, the Company recorded an adjustment to the provisional amount with a $4 million tax benefit as a component of income tax expense from continuing operations. As of December 31, 2018, the accounting for the income tax effects of the Tax Act have been completed and the total net impact resulting from the Tax Act is an expense of $57 million.

The Tax Act includes provisions for GILTI wherein taxes are imposed on foreign income in excess of a deemed return on tangible assets of foreign corporations. The Tax Act also includes a Base Erosion Anti-abuse Tax provision, which taxes certain payments from a U.S. corporation to its foreign subsidiaries.

Deferred Tax Assets and Liabilities

The Company remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. The provisional amount recorded related to the remeasurement of the deferred tax

balance was an income tax expense of $37 million. As a result of adjustments identified from filing the 2017 tax return, the total remeasurement of the deferred tax balance resulting from the Tax Act is an income tax expense of $34 million.

Foreign Tax Effects

The one-time transition tax is based on total post-1986 earnings and profits for which the Company had previously deferred U.S. income taxes. The Company recorded a provisional amount for its one-time transition tax liability on non-U.S. subsidiaries less realizable foreign tax credits (FTCs) and a write off of deferred tax liabilities on unremitted earnings, resulting in an increase in income tax expense of $24 million. As a result of adjustments identified from filing the 2017 tax return, the total impact to the transition tax resulting from the Tax Act is an income tax expense of $23 million.

The table below summarizes the impact of the Tax Act on the consolidated statements of operations.

Provision for Income Taxes

The effective tax rates reflect the proportion of income recognized by each of the Company’s operating subsidiaries, with U.S. subsidiaries taxed at the U.S. marginal corporate income tax rate of 21% in 2018 and 35%, in 2017 and 2016, U.K. subsidiaries taxed at the U.K. marginal corporate tax rate of 20%19% unless subject to U.S. tax by election ortaxed as a U.S. controlled foreign corporation (CFC), and no taxes for the Company’s Bermuda subsidiariesSubsidiaries unless subject to U.S. tax by election or aselection. In 2018, due to the Tax Act, CFCs apply the local marginal corporate tax rate. In addition, the Tax Act creates a new requirement that a portion of the GILTI earned by CFCs must be included currently in the gross income of the CFCs' U.S. controlled foreign corporation.shareholder. For periods subsequent to April 1, 2015,2017, the U.K. corporation tax rate has been reduced to 20% and is expected to remain unchanged until19%. For the periods between April 1, 2017. For period April 1, 2014 to April 1, 2015 and March 31, 2017, the U.K. corporation tax rate was 21% resulting in a blended tax rate of 20.25% in 2015.20%. The Company’s overall effective tax rate fluctuates based on the distribution of income across jurisdictions.

The change in liability for uncertain tax positions for 2018 is driven by the closure of the 2013 – 2014 tax years, see "Audits" below for further discussion.

The expected tax provision at statutory rates in taxable jurisdictions is calculated as the sum of pretax income in each jurisdiction multiplied by the statutory tax rate of the jurisdiction by which it will be taxed. Pretax income of the Company’s subsidiaries which are not U.S. or U.K. domiciled but are subject to U.S. or U.K. tax by election, establishment of tax residency or as controlled foreign corporations, are included at the U.S. or U.K. statutory tax rate. Where there is a pretax loss in one jurisdiction and pretax income in another, the total combined expected tax rate may be higher or lower than any of the individual statutory rates.

As of December 31, 2016,2018, the Company had alternative minimum tax credits of $17$20 million which, do not expire. During 2016pursuant to the Company generated $1 million of foreignTax Act, are available as a credit to offset regular tax credit which will expire in 2026. Management believes sufficient future taxable income exists to realizeliability over the full benefit of these tax credits.next two years with any excess refundable by 2021.

As part of the CIFG Acquisition, the Company acquired $189 million of net operating losses (NOL)NOL which will begin to expire in 2033. The NOL has been limited under Internal Revenue Code Section 382 due to a change in control as a result of the acquisition. As of December 31, 2016,2018, the Company had $184$162 million of NOL’sNOLs available to offset its future U.S. taxable income.


Valuation Allowance
 
As partThe Company has $13 million of FTC carryovers from previous acquisitions and $23 million of FTC due to the Radian Asset Acquisition,Tax Act for use against regular tax in future years. FTCs will begin to expire in 2020 and will fully expire by 2027. In analyzing the future realizability of FTCs, the Company acquired $19 million ofnotes limitations on future foreign tax credits (FTC) which will expire in 2020. Of that balance, $11 million was guaranteed at the time of the purchase with an additional $8 million allocated after filing 2015 tax return.source income due to overall foreign losses as negative evidence. After reviewing positive and negative evidence, the Company came to the conclusion that it is more likely than not that the FTC of $36 million will not be utilized, and therefore recorded a valuation allowance with respect to this tax attribute.

The Company came to the conclusion that it is more likely than not that the remaining net deferred tax asset will be fully realized after weighing all positive and negative evidence available as required under GAAP. The positive evidence that was considered included the cumulative income the Company has earned over the last three years, and the significant unearned premium income to be included in taxable income. The positive evidence outweighs any negative evidence that exists. As such, the Company believes that no valuation allowance is necessary in connection with thisthe remaining net deferred tax asset. The Company will continue to analyze the need for a valuation allowance on a quarterly basis.


Audits

As of December 31, 2018, AGUS hashad open tax years with the U.S. Internal Revenue Service (IRS)IRS for 2009 forward and is currently under audit for the 2009-2012 tax years.2015 to present. In December of 2016, the IRS issued a Revenue Agent Report (RAR)for the 2009 - 2012 audit period, which did not identify any material adjustments that were not already accounted for in the prior periods. It is expected thatIn April 2017, the Company received a final letter from the IRS to close the audit will close in 2017with no additional findings or changes, and depending onas a result the final outcome, reserves forCompany released previously recorded uncertain tax positions may be released.position reserves and accrued interest of approximately $37 million in the second quarter of 2017. The 2013 and 2014 tax years closed in 2018. Assured Guaranty Oversees U.S.Overseas US Holdings Inc. has open tax years of 20132015 forward. The Company's U.K. subsidiaries are not currently under examination and have open tax years of 20142016 forward. CIFGNA, which was acquired by AGC during 2016, is not currently under examination and has open tax years of 2013 forward.2015 to the date of acquisition. In September 2018, the Company's French subsidiary, CIFGE (which was subsequently merged with AGE), concluded an examination for the period January 1, 2015 through December 31, 2016 with no material adjustments and has open tax years from 2017 to the date of its merger with AGE.

The Company's policy is to recognize interest related to uncertain tax positions in income tax expense and has accrued $1 million for the full year 2018, $1 million for the full year 2017 and $2 million for 2016 and $1 million perthe full year for the year ended 2015 and 2014 respectively.2016. As of December 31, 20162018 and December 31, 2015,2017, the Company has accrued $7$2 million and $5$3 million of interest, respectively.

The total amount of reserves for unrecognized tax positions, including accrued interest, as of December 31, 20162018 and December 31, 2017 that would affect the effective tax rate, if recognized.recognized, was $16 million and $31 million, respectively. The Company released $18 million of previously recorded uncertain tax position reserves and accrued interest in 2018 due to the closing of the 2013 and 2014 tax years.

Tax Treatment of CDS

The Company treats the guaranty it provides on CDS as an insurance contract for tax purposes and as such a taxable loss does not occur until the Company expects to make a loss payment to the buyer of credit protection based upon the occurrence of one or more specified credit events with respect to the contractually referenced obligation or entity. The Company holds its CDS to maturity, at which time any unrealized fair value loss in excess of credit-related losses would revert to zero. The tax treatment of CDS is an unsettled area of the law. The uncertainty relates to the IRS determination of the income or potential loss associated with CDS as either subject to capital gain (loss) or ordinary income (loss) treatment. In treating CDS as insurance contracts the Company treats both the receipt of premium and payment of losses as ordinary income and believes it is more likely than not that any CDS credit related losses will be treated as ordinary by the IRS. To the extent the IRS takes the view that the losses are capital losses in the future and the Company incurred actual losses associated with the CDS, the Company would need sufficient taxable income of the same character within the carryback and carryforward period available under the tax law.

13.Reinsurance and Other Monoline Exposures
 
The Company assumes exposure on insured obligations (Assumed Business) and may cede portions of its exposure on obligations it has insured (Ceded Business) in exchange for premiums, net of any ceding commissions. Substantially all of the Company’s Assumed Business and Ceded Business relates to financial guaranty business, except for a modest amount that relates to AGRO's non-financial guaranty business. The Company historically entered into, and with respect to new business originated by AGRO continues to enter into, ceded reinsurance contracts in order to obtain greater business diversification and reduce the net potential loss from large risks.

Accounting Policy

For business assumed and ceded, the accounting model of the underlying direct financial guaranty contract dictates the accounting model used for the reinsurance contract (except for those eliminated as FG VIEs). For any assumed or ceded financial guaranty insurance premiums and financial guaranty insurance losses, the accounting models described in Note 6 are followed. For any assumed or ceded credit derivative contracts, the accounting model in Note 8 is followed.


Assumed and Ceded Financial Guaranty Business
 
The Company assumeshas assumed financial guaranty business (Assumed Financial Guaranty Business) from third party insurers, and reinsurers, includingprimarily other monoline financial guaranty companies. Undercompanies that currently are in runoff and no longer actively writing new business (Legacy Monoline Insurers). The Company, if required, secures its reinsurance obligations to these relationships,Legacy Monoline Insurers, typically by depositing in trust assets with a market value equal to its assumed liabilities calculated on a U.S. statutory basis.

As of December 31, 2018, the majority of the Company’s Assumed Financial Guaranty Business from Legacy Monoline Insurers consists of business that AGC assumed in the SGI Transaction effective as of June 1, 2018, pursuant to which AGC (among other things) assumed, generally on a 100% quota share basis, substantially all of SGI’s insured portfolio. The par value on that date of the exposures reinsured totaled approximately $11 billion. The reinsured portfolio consists predominantly of public finance and infrastructure obligations that meet Assured Guaranty’s new business underwriting criteria. See Note 2, Assumption of Insured Portfolio and Business Combinations for additional information on the SGI Transaction. The balance of the Company’s Assumed Financial Guaranty Business mainly consists of business that the Company assumes a portion of(predominantly AGC and/or AG Re) assumed prior to the ceding company’s insured risk in exchange for a portion of the ceding Company's premium for the insured risk (typically, net of a ceding commission). 2008-2009 financial crisis from other Legacy Monoline Insurers.

The Company’s facultative and treaty agreements with the Legacy Monoline Insurers are generally subject to termination at the option of the ceding company:

if the Company fails to meet certain financial and regulatory criteria andcriteria;

if the Company fails to maintain a specified minimum financial strength rating, or

upon certain changes of control of the Company.
 
Upon termination under these conditions,due to one of the above events, the Company maytypically would be required (under some of its reinsurance agreements) to return to the ceding company unearned premiums (net of ceding commissions) and loss reserves, calculated on a U.S. statutory basis, of accounting, attributable to reinsurancethe assumed pursuant to such agreementsbusiness (plus in certain cases, an additional required amount), after which the Company would be released from liability with respect to the Assumed Business.

Upon the occurrence of the conditions set forth in the first bullet above, whether or not an agreement is terminated, the Company may be required to obtain a letter of credit or alternative form of security to collateralize its obligation to perform under such agreement or it may be obligated to increase the level of ceding commission paid.business.
 
The downgrade of the financial strength ratings of AG Re or of AGC gives certain ceding companies the right to recapture business they had ceded to AG Re and AGC, which would lead to a reduction in the Company's unearned premium reserve and related earnings on such reserve. With respect to a significant portion of the Company's in-force financial guaranty assumed business, based on AG Re's and AGC's current ratings and subject to the terms of each reinsurance agreement, the third party ceding company may have the right to recapture business it had ceded to AG Re and/or AGC, and in connection therewith, to receive payment from AG Re or AGC of an amount equal to the statutory unearned premium (net of ceding commissions) and statutory loss reserves (if any) associated with that business, plus, in certain cases, an additional required payment. As of December 31, 2016,2018, if each third party insurercompany ceding business to AG Re and/or AGC had a right to recapture such business, and chose to exercise such right, the aggregate amounts that AG Re and AGC could be required to pay to all such companies would be approximately $45$42 million and $18$326 million, respectively.

The Company has Ceded Businessceded financial guaranty business to non-affiliated companies to limit its exposure to risk. Under these relationships, the Company ceded a portion of its insured risk to the reinsurer in exchange for the reinsurer receiving a share of the Company's premiums for the insured risk (typically, net of a ceding commission). The Company remains primarily liable for all risks it directly underwrites and is required to pay all gross claims. It then seeks reimbursement from the reinsurer for its proportionate share of claims. The Company may be exposed to risk for this exposure if it were required to pay the gross claims and not be able to collect ceded claims from an assuming company experiencing financial distress. A number of the financial guaranty insurers to which the Company has ceded par have experienced financial distress and been downgraded by the rating agencies as a result. In addition, state insurance regulators have intervened with respect to some of these insurers. The Company’s ceded contracts generally allow the Company to recapture Ceded Businessceded financial guaranty business after certain triggering events, such as reinsurer downgrades.
Over the past several years, the Company has entered into several commutations in order to reassume previously ceded books of business from its reinsurers. The Company has also canceled assumed reinsurance contracts.

Other Monoline Exposures
In addition to assumed and ceded reinsurance arrangements, the Company may also have exposure to some financial guaranty reinsurers (i.e., monolines) in other areas. Second-to-pay insured par outstanding represents transactions the Company has insured that were previously insured by third party insurers and reinsurers. The Company underwrites such transactions based on the underlying insured obligation without regard to the primary insurer. Another area of exposure is in the investment portfolio where the Company holds fixed-maturity securities that are wrapped by monolines and whose value may change based on the rating of the monoline. As of December 31, 2016, based on fair value, the Company had fixed-maturity securities in its investment portfolio consisting of $110 million insured by National, $83 million insured by Ambac and $8 million insured by other guarantors.respectively.

This facility replaces a similar $450$400 million aggregate

excess of loss reinsurance facility, of which $360 million was placed with unaffiliated reinsurers, that AGC, AGM and MAC had entered into effective January 1, 20142016 and which terminated on December 31, 2015.2017. The new facility covers losses occurring either from January 1, 20162018 through December 31, 2023,2024, or January 1, 20172019 through December 31, 2024,2025, at the option of AGC, AGM and MAC. It terminates on January 1, 2018,2020, unless AGC, AGM and MAC choose to extend it. The new facility covers certain U.S. public finance creditsexposures insured or reinsured by AGC, AGM and MAC as of September 30, 2015,2017, excluding creditsexposures that were rated non-investmentbelow investment grade as of December 31, 20152017 by Moody’s or S&P or internally by AGC, AGM or MAC and is subject to certain per credit limits. Among the creditsexposures excluded are those associated with the Commonwealth of Puerto Rico and its related authorities and public corporations. The new facility attaches when AGC’s, AGM’s and MAC’s net losses (net of AGC’s and AGM's reinsurance (including from affiliates) and net of recoveries) exceed $1.25$0.8 billion in the aggregate. The new facility covers a portion of the next $400 million of losses, with the reinsurersreinsurer assuming pro rata in the aggregate $360$180 million of the $400 million of losses and AGC, AGM and MAC jointly retaining the remaining $40$220 million. The reinsurers arereinsurer is required to be rated at least AA- or to post collateral sufficient to provide AGC, AGM AGC and MAC with the same reinsurance credit as reinsurers rated AA-. AGC, AGM AGC and MAC are obligated to pay the reinsurers theirreinsurer its share of recoveries relating to losses during the coverage period in the covered portfolio. AGC, AGM and MAC paid approximately $9$3.2 million of premiums in 20162018 for the term January 1, 20162018 through December 31, 20162018 and haddeposited approximately $9$3.2 million ofin cash ininto a trust accountsaccount for the benefit of the reinsurersreinsurer to be used to pay the premiumpremiums for January 1, 2017 through2019. The main differences between the new facility and the prior facility that terminated on December 31, 2017.
2017 are the reinsurance attachment point ($0.8 billion versus $1.25 billion), the total reinsurance coverage ($180 million part of $400 million versus $360 million part of $400 million) and the annual premium ($3.2 million versus $9 million).

Assumed and Ceded Non-Financial Guaranty Business

As described in Note 4, Outstanding Exposure, Non-Financial Guaranty Insurance, the Company, through AGRO, assumes non-financial guaranty business from third party insurers (Assumed Non-Financial Guaranty Business). It also retrocedes some of this business to third party reinsurers. A downgrade of AGRO’s financial strength rating by S&P below “A” would require AGRO to post, as of December 31, 2018, an estimated $2 million of collateral in respect of certain of its Assumed Non-Financial Guaranty Business. A further downgrade of AGRO’s S&P rating below A- would give the company ceding such business the right to recapture the business for AGRO’s collateral amount, and, if also accompanied by a downgrade of AGRO's financial strength rating by A.M. Best Company, Inc. below A-, would also require AGRO to post, as of December 31, 2018, an estimated $8 million of collateral in respect of a different portion of AGRO’s Assumed Non-Financial Guaranty Business. AGRO’s ceded contracts generally have equivalent provisions requiring the assuming reinsurer to post collateral and/or allowing AGRO to recapture the ceded business upon certain triggering events, such as reinsurer rating downgrades.

Legal Proceedings

Lawsuits arise in the ordinary course of the Company’s business. It is the opinion of the Company’s management, based upon the information available, that the expected outcome of litigation against the Company, individually or in the aggregate, will not have a material adverse effect on the Company’s financial position or liquidity, although an adverse resolution of litigation against the Company in a fiscal quarter or year could have a material adverse effect on the Company’s results of operations in a particular quarter or year.

In addition, in the ordinary course of their respective businesses, certain of the Company'sAGL's subsidiaries assert claims in legal proceedings against third parties to recover losses paid in prior periods or prevent losses in the future, including those describedfuture. For example, the Company has commenced a number of legal actions in the Federal District Court for Puerto Rico to enforce its rights with respect to the obligations it insures of Puerto Rico and various of its related authorities and public corporations. See "Exposure to Puerto Rico" section of Note 4, Outstanding Exposure, for a description of such actions. See "Recovery Litigation,"Litigation" section of Note 5, Expected Loss to be Paid. For example, as described there, in January 2016 the Company commenced an actionPaid, for declaratory judgment and injunctive relief in the U.S. District Court for the Districta description of recovery litigation unrelated to Puerto Rico to invalidate executive orders issued by the Governor of Puerto Rico directing the retention or transfer of certain taxes and revenues pledged to secure the payment of certain bonds insured by the Company, and in July 2016, the Company filed a motion and form of complaint in the U.S. District Court for the District of Puerto Rico seeking relief from the PROMESA stay in order to file a complaint to protect its interest in certain pledged PRHTA toll revenues. As another example, in December 2008, the Company filed a claim in the Supreme Court of the State of New York against an investment manager in a transaction it insured alleging breach of fiduciary duty, gross negligence and breach of contract.Rico. The amounts, if any, the Company will recover in these and other proceedings to recover losses are uncertain, and recoveries, or failure to obtain recoveries, in any one or more of these proceedings during any quarter or year could be material to the Company's results of operations in that particular quarter or year.
The Company also receives subpoenas duces tecum and interrogatories from regulators from time to time.

Accounting Policy
    
The Company establishes accruals for litigation and regulatory matters to the extent it is probable that a loss has been incurred and the amount of that loss can be reasonably estimated. For litigation and regulatory matters where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established, but if the matter is material, it is disclosed, including matters discussed below. The Company reviews relevant information with respect to its litigation and regulatory matters on a quarterly and annual basis and updates its accruals, disclosures and estimates of reasonably possible loss based on such reviews.


Litigation

Proceedings Relating to the Company’s Financial Guaranty Business
The Company receives subpoenas duces tecum and interrogatories from regulators from time to time.
On November 28, 2011, Lehman Brothers International (Europe) (in administration) (LBIE) sued AGFP,AG Financial Products Inc. (AGFP), an affiliate of AGC which in the past had provided credit protection to counterparties under CDS. AGC acts as the credit support provider of AGFP under these CDS. LBIE’s complaint, which was filed in the Supreme Court of the State of New York, alleged that AGFP improperly terminatedasserted a claim for breach of the implied covenant of good faith and fair dealing based on AGFP's termination of nine credit derivative transactions between LBIE and AGFP and improperly calculatedasserted claims for breach of contract and breach of the termination payment in connection with theimplied covenant of good faith and fair dealing based on AGFP's termination of 28 other credit derivative transactions between LBIE and AGFP.AGFP and AGFP's calculation of the termination payment in connection with those 28 other credit derivative transactions. Following defaults by LBIE, AGFP properly terminated the transactions in question in compliance with the agreement between AGFP and LBIE, and calculated the termination payment properly. AGFP calculated that LBIE owes AGFP approximately $29 million in connection with the termination of the credit derivative transactions, whereas LBIE asserted in the complaint that AGFP owes LBIE a termination payment of approximately $1.4 billion. On February 3, 2012, AGFP filed a motion to dismiss certainthe claims for breach of the countsimplied covenant of good faith in theLBIE's complaint, and on March 15, 2013, the court granted AGFP's motion to dismiss in respect of the count relating to improper termination of the nine credit derivative transactions and denied AGFP's motion to dismiss the counts relatingnarrowed LBIE's claim with respect to the remaining28 other credit derivative transactions. On February 22, 2016, AGFP filed a motion for summary judgment on the remaining causes of action asserted by LBIE and on AGFP's counterclaims. Oral argument on AGFP's motion took place on July 21, 2016. LBIE's administrators disclosed in an April 10, 2015 report to LBIE’s unsecured creditors that LBIE's valuation expert has calculated LBIE's claim for damages in aggregate for the 28 transactions to range between a minimum of approximately $200 million and a maximum of approximately $500 million, depending on what adjustment, if any, is made for AGFP's credit risk and excluding any applicable interest.

On September 25, 2013, Wells Fargo Bank, N.A., as trust administrator of the MASTR Adjustable Rate Mortgages Trust 2007-3 (Wells Fargo), AGFP filed an interpleader complaint in the U.S. District Court for the Southern District of New York seeking adjudication of a dispute between Wales LLC (Wales) and AGM as to whether AGM is entitled to reimbursement from

certain cashflows for principal claims paid in respect of insured certificates. On September 30, 2016, the court issued an opinion denying a motion for summary judgment on the pleadings filedremaining causes of action asserted by Wales. On January 3, 2017,LBIE and on AGFP's counterclaims and on July 2, 2018, the Court approved a Stipulationcourt granted in part and Orderdenied in part AGFP’s motion. The court dismissed, in its entirety, LBIE’s remaining claim for breach of Dismissalthe implied covenant of Wales from the action due to Wales having sold its interests in the MASTR Adjustable Rate Mortgages Trust 2007-3 certificates. On February 9, 2017, the remaining parties submitted a Stipulationgood faith and (Proposed) Orderfair dealing and also dismissed LBIE’s claim for breach of Voluntary Dismissal, which the Court has not yet so-ordered. The Company estimates that an adverse outcomecontract solely to the interpleader proceeding could increase losses on the transaction by approximately $10 - $20 million, net of expected settlement payments and reinsurance in force.
On December 22, 2014, Deutsche Bank National Trust Company, as indenture trustee for the AAA Trust 2007-2 Re-REMIC (the Trustee), filed a “trust instructional proceeding” petition in the State of California Superior Court (Probate Division, Orange County), seeking the court’s instruction as to how it should allocate the losses resulting from its December 2014 sale of four RMBS owned by the AAA Trust 2007-2 Re-REMIC. This sale of approximately $70 million principal balance of RMBS was made pursuant to AGC’s liquidation direction in November 2014, and resulted in approximately $27 million of gross proceeds to the Re-REMIC. On December 22, 2014, AGC directed the indenture trustee to allocate to the uninsured Class A-3 Notes the losses realized from the sale. On May 4, 2015, the Superior Court rejected AGC’s allocation direction, and ordered the Trustee to allocate to the Class A-3 noteholders a pro rata share of the $27 million of gross proceeds. AGC is appealing the Superior Court’s decision to the California Court of Appeal.

On May 28, 2014, Houston Casualty Company Europe, Seguros y Reseguros, S.A. (HCCE) notified Radian Assetextent that it was demanding arbitration against Radian Assetis based upon AGFP’s conduct in connection with housing cooperative losses presentedthe auction. With respect to Radian Asset by HCCE under several yearsLBIE’s claim for breach of quota-share surety reinsurance contracts. Through November 30, 2015, HCCE had presented AGC, as successor to Radian Asset,contract, the court held that there are triable issues of fact regarding whether AGFP calculated its loss reasonably and in good faith. On October 1, 2018, AGFP filed an appeal with approximately €15 million in claims.  In January 2016, Assured Guaranty and HCCE settled all the claims related to the Spanish housing cooperative losses.

Proceedings Related to AGMH’s Former Financial Products Business
     The following is a description of legal proceedings involving AGMH’s former Financial Products Business. Although the Company did not acquire AGMH’s former Financial Products Business, which included AGMH’s former GIC business, medium term notes business and portions of the leveraged lease businesses, certain legal proceedings relating to those businesses were against entities that the Company did acquire. While Dexia SA and Dexia Crédit Local S.A. (together, Dexia) have paid all expenses and settlement amounts due to date as a result of the proceedings described below, such indemnification might not be sufficient to fully hold the Company harmless against any injunctive relief or civil or criminal sanction that is imposed against AGMH or its subsidiaries as a result of any potential newly asserted claims related to these matters.
Governmental Investigations into Former Financial Products Business
AGMH and/or AGM received subpoenas duces tecum and interrogatories or civil investigative demands from the Attorneys General of the States of Connecticut, Florida, Illinois, Massachusetts, Missouri, New York, Texas and West Virginia relating to their investigations of alleged bid rigging of municipal GICs. In addition, AGMH received a subpoena from the AntitrustAppellate Division of the Department of Justice in November 2006 issued in connection with an ongoing criminal investigation of bid rigging of awards of municipal GICs and other municipal derivatives. AGMH responded to such requests when they were received several years ago. While it is possible AGMH may receive additional inquiries from these or other regulators, the Company is not currently aware that any governmental authority, including such Attorneys General or the Department of Justice, are actively pursuing or contemplating legal proceedings with respect to AGMH's former Financial Products Business.
Lawsuits Relating to Former Financial Products Business

From 2008 through 2010, complaints were brought on behalf of a purported class of state, local and municipal government entities alleging federal antitrust violations in the municipal derivatives industry, seeking damages and alleging, among other things, a conspiracy to fix the pricing of, and manipulate bids for, municipal derivatives, including GICs. These actions were consolidated before one judge in the Southern District of New York as Municipal Derivatives Antitrust Litigation (MDL 1950). Following motions to dismiss, amended class action complaints were filed on behalf of a putative class of plaintiffs. The most recently amended, operative class action complaint does not list AGMH or its affiliates as defendants or co-conspirators. On July 8, 2016, the MDL 1950Supreme Court entered an order approving settlement of the remaining class claims, resolving the putative class case.

In addition, the Attorney General of the State of West Virginia filed a lawsuit that, as amended, named AGM and Assured Guaranty U.S. Holdings as defendants and alleged a conspiracy to decrease the returns that West Virginia public entities earned on municipal derivative instruments. Also, approximately 19 California and New York, government entities

brought individual lawsuits that were not a partFirst Judicial Department, seeking reversal of the class action and that did not dismiss AGMH or its affiliates. All these cases were transferred to the Southern District of New York and consolidated with MDL 1950 for pretrial purposes. In June and July 2016, Dexia executed settlement agreements covering the action brought by the Attorney Generalportions of the Statelower court's ruling denying AGFP’s motion for summary judgment with respect to LBIE’s sole remaining claim for breach of West Virginiacontract. On January 17, 2019, the Appellate Division affirmed the Supreme Court's decision, holding that the lower court correctly determined that there are triable issues of fact regarding whether AGFP calculated its loss reasonably and the actions brought by the individual California and New York plaintiffs, and on July 1, 2016 and July 27, 2016, respectively, the MDL 1950 court dismissed with prejudice the claims against Assured Guaranty U.S. Holdings and AGM in all such actions. Those settlements release all claims as to Assured Guaranty U.S. Holdings, AGMH and AGM, as well as their parents, subsidiaries and affiliates.good faith.
  
16.Long-Term Debt and Credit Facilities
      
Accounting Policy

Long-term debt is recorded at principal amounts net of any unamortized original issue discount or premium and unamortized acquisition date fair value adjustment for AGM and AGMH debt (as of the date of the AGMH acquisition).debt. Discounts and acquisition date fair value adjustments are accreted into interest expense over the life of the applicable debt.

Long Term Debt

The Company has outstanding long-term debt comprising primarily consisting of debt issued by AGUS and AGMH. AGUS has issued 7% Senior Notes, 5% Senior Notes and Series A, Enhanced Junior Subordinated Debentures. AGMH has issued 6 7/8% Quarterly Income Bonds Securities (QUIBS), 6.25% Notes and 5.6% Notes, as well as $300 million Junior Subordinated Debentures. All of suchthe AGUS and AGMH debt is fully and unconditionally guaranteed by AGL; AGL's guarantee of the junior subordinated debentures is on a junior subordinated basis.

In 2017, the United Kingdom’s Financial Conduct Authority announced that after 2021 it would no longer compel banks to submit the rates required to calculate LIBOR. This announcement indicates that the continuation of LIBOR on the current basis cannot and will not be guaranteed after 2021. Consequently, at this time, it is not possible to predict whether and to what extent banks will continue to provide submissions for the calculation of LIBOR. While regulators have suggested substitute rates, including the Secured Overnight Financing Rate, the impact of the discontinuance of LIBOR, if it occurs, will be contract-specific. Some of the debt issued by the Company, as well as CCS from which it benefits, pay interest tied to LIBOR. The Company cannot at this time predict the impact of the discontinuance of LIBOR, if it occurs.

Recourse Credit Facilities
2009 Strip Coverage Facility
In connection with the Company's acquisition of AGMH and its subsidiaries from Dexia Holdings Inc., AGM agreed to retain the risks relating to the debt and strip policy portions of the leveraged lease business.
In a leveraged lease transaction, a tax-exempt entity (such as a transit agency) transfers tax benefits to a tax-paying entity by transferring ownership of a depreciable asset, such as subway cars. The tax-exempt entity then leases the asset back from its new owner.
If the lease is terminated early, the tax-exempt entity must make an early termination payment to the lessor. A portion of this early termination payment is funded from monies that were pre-funded and invested at the closing of the leveraged lease transaction (along with earnings on those invested funds). The tax-exempt entity is obligated to pay the remaining, unfunded portion of this early termination payment (known as the strip coverage) from its own sources. AGM issued financial guaranty insurance policies (known as strip policies) that guaranteed the payment of these unfunded strip coverage amounts to the lessor, in the event that a tax-exempt entity defaulted on its obligation to pay this portion of its early termination payment. Following such events, AGM can then seek reimbursement of its strip policy payments from the tax-exempt entity, and can also sell the transferred depreciable asset and reimburse itself from the sale proceeds.
Currently, all the leveraged lease transactions in which AGM acts as strip coverage provider are breaching a rating trigger related to AGM and are subject to early termination. However, early termination of a lease does not result in a draw on the AGM policy if the tax-exempt entity makes the required termination payment. If all the leases were to terminate early and the tax-exempt entities do not make the required early termination payments, then AGM would be exposed to possible liquidity claims on gross exposure of approximately $953 million as of December 31, 2016. To date, none of the leveraged lease transactions that involve AGM has experienced an early termination due to a lease default and a claim on the AGM policy. At December 31, 2016, approximately $1.5 billion of cumulative strip par exposure had been terminated since 2008 on a consensual basis. The consensual terminations have resulted in no claims on AGM.
On July 1, 2009, AGM and Dexia Crédit Local S.A., acting through its New York Branch (Dexia Crédit Local (NY)), entered into a credit facility (the Strip Coverage Facility). Under the Strip Coverage Facility, Dexia Crédit Local (NY) agreed to make loans to AGM to finance all draws made by lessors on AGM strip policies that were outstanding as of November 13, 2008, up to the commitment amount. There have never been any borrowings under the Strip Coverage Facility, the amount of the leveraged leases covered by the Strip Coverage Facility has declined since July 1, 2009 and, to date, none of the leveraged

lease transactions in which AGM acts as the strip coverage provider has experienced an early termination due to a lease default. Consequently, and in view of the credit quality of the relevant tax-exempt entities and the cost of the Strip Coverage Facility, the Company determined that maintaining the Strip Coverage Facility was no longer warranted. On July 29, 2016, the parties terminated the Strip Coverage Facility.
Intercompany Credit Facility and Intercompany Debt

On October 25, 2013, AGL, as borrower, and AGUS, as lender, entered into a revolving credit facility pursuant to which AGL may, from time to time, borrow for general corporate purposes. Under the credit facility, AGUS committed to lend a principal amount not exceeding $225 million in the aggregate. SuchIn September 2018, AGL and AGUS amended the revolving credit facility to extend the commitment terminates onuntil October 25, 20182023 (the “loanloan commitment termination date”)date). The unpaid principal amount of each loan will bear interest at a fixed rate equal to 100% of the then applicable Federal short-term or mid-term interest rate as the case may be, as determined under Internal RevenueSection 1274(d) of the Code, Sec. 1274(d), and interest on all loans will be computed for the actual number of days elapsed on the basis of a year consisting of 360 days. Accrued interest on all loans will be paid on the last day of each June and December, beginning on December 31, 2013, and at maturity.  AGL must repay the then unpaid principal amounts of the loans by the third anniversary of the loan commitment termination date. No amounts are currently outstanding under the credit facility.

On March 30, 2015, AGUS loaned $200 million to AGC to facilitate the acquisition of Radian Asset on April 1, 2015. AGC repaid the loan in full on April 14, 2015.

In addition, in 2012 AGUS borrowed $90 million from its affiliate AGRO to fund the acquisition of MAC. In 2018, the maturity date was extended to November 2023. During 2018, 2017 and 2016, AGUS repaid $10 million, $10 million and $20 million, respectively, in outstanding principal as well as accrued and unpaid interest, and the parties agreed to extend the maturity date of the loan from May 2017 to November 2019.interest. As of December 31, 2016, $702018, $50 million remained outstanding.


Committed Capital Securities

On April 8, 2005,Each of AGC and AGM have entered into separateput agreements (the Put Agreements) with four separate custodial trusts (each, a Custodial Trust) pursuantallowing AGC and AGM, respectively, to which AGC may, at its option, cause eachissue an aggregate of $200 million of non-cumulative redeemable perpetual preferred securities to the Custodial Trusts to purchase up totrusts in exchange for cash. Each custodial trust was created for the primary purpose of issuing $50 million face amount of perpetual preferred stockCCS, investing the proceeds in high-quality assets and entering into put options with AGC or AGM, as applicable. The Company does not consider itself to be the primary beneficiary of the trusts and the trusts are not consolidated in Assured Guaranty's financial statements.  

The trusts provide AGC (the AGC Preferred Stock). The custodial trusts were created as a vehicle for providing capital support to AGC by allowing AGC to obtain immediateand AGM access to new equity capital at itstheir respective sole discretion at any time through the exercise of the put option. If the put options were exercised, AGC would receive $200 million in return for the issuanceoptions. Upon AGC's or AGM's exercise of its own perpetualput option, the relevant trust will liquidate its portfolio of eligible assets and use the proceeds to purchase the AGC or AGM preferred stock, as applicable. AGC or AGM may use the proceeds from its sale of which may be usedpreferred stock to the trusts for any purpose, including the payment of claims. The put optionsagreements have not been exercised through theno scheduled termination date of this filing.
Distributions on theor maturity. However, each put agreement will terminate if (subject to certain grace periods) specified events occur. Both AGC CCS are determined pursuant to an auction process. Beginning on April 7, 2008 this auction process failed, thereby increasing the annualized rate on the AGC CCS to one-month LIBOR plus 250 basis points.
In June 2003, $200 million of “AGM CPS”, money market preferred trust securities, were issued by trusts created for the primary purpose of issuing theand AGM CPS, investing the proceeds in high-quality commercial paper and selling put options to AGM, allowing AGM to issue the trusts non-cumulative redeemable perpetual preferred stock (the AGM Preferred Stock) of AGM in exchange for cash. There are four trusts, each with an initial aggregate face amount of $50 million. These trusts hold auctions every 28 days, at which time investors submit bid orders to purchase AGM CPS. If AGM were to exercise a put option, the applicable trust would transfer the portion of the proceeds attributable to principal received upon maturity of its assets, net of expenses, to AGM in exchange for AGM Preferred Stock. AGM pays a floating put premium to the trusts, which represents the difference between the commercial paper yield and the winning auction rate (plus all fees and expenses of the trust). If an auction does not attract sufficient clearing bids, however, the auction rate is subject to a maximum rate of one-month LIBOR plus 200 basis points for the next succeeding distribution period. Beginning in August 2007, the AGM CPS required the maximum rate for each of the relevant trusts. AGM continuescontinue to have the ability to exercise itstheir respective put optionoptions and cause the related trusts to purchase their preferred stock.

Prior to 2008 or 2007, the amounts paid on the CCS were established through an auction process. All of those auctions failed in 2008 or 2007, and the rates paid on the CCS increased to their respective maximums. The annualized rate on the AGC CCS is one-month LIBOR plus 250 bps, and the annualized rate on the AGM Preferred Stock. The trusts provide AGM access to new capital at its sole discretion through the exercise of the put options. As of December 31, 2016 the put option had not been exercised.CPS is one-month LIBOR plus 200 bps.

17.Earnings Per Share
 
Accounting Policy

The Company computes EPS using a two-class method, by includingwhich is an earnings allocation formula that determines EPS for (i) each class of common stock (the Company has a single class of common stock), and (ii) participating securities which entitle their holdersaccording to receive nonforfeitable dividends or dividend equivalents before vesting.declared (or accumulated) and participation rights in undistributed earnings. Restricted stock awards and share units under the AGC supplemental executive retirement plan (AGC SERP) are considered participating securities as they received non-forfeitable rights to dividends at the same rate as(or dividend equivalents) similar to common stock.

The two-class method of computing EPS is an earnings allocation formula that determines EPS for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Basic EPS is then calculated by dividing net (loss) income available to common shareholders of Assured Guaranty by the weighted‑average number of common shares outstanding during the period. Diluted EPS adjusts basic EPS for the effects of restricted stock, restricted stock units, stock options and other potentially dilutive financial instruments (“dilutive securities”)(dilutive securities), only in the periods in which such effect is dilutive. The effect of the dilutive securities is reflected in diluted EPS by application of the more dilutive of (1) the treasury stock method or (2) the two-class method assuming nonvested shares are not converted into common shares. The Company has a single class of common stock.

18.Shareholders' Equity
    
Share Issuances

AGL has authorized share capital of $$5 million divided into 500,000,000 shares with a par value $0.01 per share. Except as described below, AGL's common shares have no preemptive rights or other rights to subscribe for additional common shares, no rights of redemption, conversion or exchange and no sinking fund rights. In the event of liquidation, dissolution or winding-up, the holders of AGL's common shares are entitled to share equally, in proportion to the number of common shares held by such holder, in AGL's assets, if any remain after the payment of all its liabilities and the liquidation preference of any outstanding preferred shares. Under certain circumstances, AGL has the right to purchase all or a portion of the shares held by a shareholder at fair market value. All of the common shares are fully paid and non assessable. Holders of AGL's common shares are entitled to receive dividends as lawfully may be declared from time to time by AGL's Board of Directors (the Board).

In general, and except as provided below, shareholders have one vote for each common share held by them and are entitled to vote with respect to their fully paid shares at all meetings of shareholders. However, if, and so long as, the common shares (and other of AGL's shares) of a shareholder are treated as "controlled shares" (as determined pursuant to section 958 of the Code) of any U.S. Person and such controlled shares constitute 9.5% or more of the votes conferred by AGL's issued and outstanding shares, the voting rights with respect to the controlled shares owned by such U.S. Person shall be limited, in the aggregate, to a voting power of less than 9.5% of the voting power of all issued and outstanding shares, under a formula specified in AGL's Bye-laws. The formula is applied repeatedly until there is no U.S. Person whose controlled shares constitute 9.5% or more of the voting power of all issued and outstanding shares and who generally would be required to recognize income with respect to AGL under the Code if AGL were a controlled foreign corporationCFC as defined in the Code and if the ownership threshold under the Code were 9.5% (as defined in AGL's Bye-Laws as a 9.5% U.S. Shareholder).

Subject to AGL's Bye-Laws and Bermuda law, AGL's Board has the power to issue any of AGL's unissued shares as it determines, including the issuance of any shares or class of shares with preferred, deferred or other special rights.

Under AGL's Bye-Laws and subject to Bermuda law, if AGL's Board determines that any ownership of AGL's shares may result in adverse tax, legal or regulatory consequences to the Company, any of the Company's subsidiaries or any of its shareholders or indirect holders of shares or its Affiliates (other than such as AGL's Board considers de minimis), the Company has the option, but not the obligation, to require such shareholder to sell to AGL or to a third party to whom AGL assigns the repurchase right the minimum number of common shares necessary to avoid or cure any such adverse consequences at a price determined in the discretion of the Board to represent the shares' fair market value (as defined in AGL's Bye-Laws). In addition, AGL's Board may determine that shares held carry different voting rights when it deems it appropriate to do so to (i) avoid the existence of any 9.5% U.S. Shareholder; and (ii) avoid adverse tax, legal or regulatory consequences to AGL or any of its subsidiaries or any direct or indirect holder of shares or its affiliates. "Controlled shares" includes, among other things, all shares of AGL that such U.S. Person is deemed to own directly, indirectly or constructively (within the meaning of section 958 of the Code). Further, these provisions do not apply in the event one shareholder owns greater than 75% of the voting power of all issued and outstanding shares.

Under these provisions, certain shareholders may have their voting rights limited to less than one vote per share, while other shareholders may have voting rights in excess of one vote per share. Moreover, these provisions could have the effect of reducing the votes of certain shareholders who would not otherwise be subject to the 9.5% limitation by virtue of their direct share ownership. AGL's Bye-laws provide that it will use its best efforts to notify shareholders of their voting interests prior to any vote to be taken by them.

Share Repurchases

On February 22, 2017,Accounting Policy

The Company records share repurchases as a reduction to common stock and additional paid-in capital. Once additional paid-in capital has been exhausted, share repurchases are recorded as a reduction to common stock and retained earnings.

Share Repurchases

As of March 1, 2019, the Company was authorized to purchase $350 million of its common shares; including a $300 million authorization that was approved by the Board authorized an additional $300 million of share repurchases, bringing the total remaining authorization to $407 million as ofon February 23, 2017.27, 2019. The Company expects to repurchase shares from time to time in the open market or in privately negotiated transactions. The timing, form and amount of the share repurchases under the program are at the discretion of management and will depend on a variety of factors, including funds available at the parent company, other potential uses for such funds, market conditions, the Company's capital position, legal requirements and other factors. The repurchase program may be modified, extended or terminated by the Board at any time. It does not have an expiration date.

As indicated in Note 14, Related Party Transactions, in 2017 the Company repurchased shares from its Chief Executive Officer and former General Counsel.

Deferred Compensation

Each of the Chief Executive Officer and the General Counsel of the Company has elected to invest a portion of his AGL SERP account in the employer stock fund within the AGL SERP. Each unit in the employer stock fund represents the right to receive one AGL common share upon a distribution from the AGL SERP. Each unit equals the number of AGL common shares which could have been purchased with the value of the account deemed invested in the employer stock fund as of the date of such election. The election to invest in the employer stock fund is irrevocable (i.e., any portion of a AGL SERP account allocated to the employer stock fund and invested in units shall remain allocated to the employer stock fund until the participant receives a distribution from AGL SERP). At the same time such investment elections were made, the Company purchased AGL common shares and placed such shares in trust to be distributed to the Chief Executive Officer and the General Counsel upon a distribution from the AGL SERP in settlement of their units invested in the employer stock fund. As of December 31, 2016 and 2015, the Company had 320,193 and 320,193 shares, respectively, in the trust. The Company recorded the purchase of such shares in “deferred equity compensation” in the consolidated balance sheet. As indicated in Note 14, Related Party Transactions, on January 6, 2017, the 320,193 shares were distributed in settlement of the AGL SERP units and therefore, there are no shares remaining in trust.

Certain executives of the Company elected to invest a portion of their AGC SERP accounts in the employer stock fund in the AGC SERP. Each unit in the employer stock fund represents the right to receive one AGL common share upon a distribution from the AGC SERP. Each unit equals the number of AGL common shares which could have been purchased with the value of the account deemed invested in the employer stock fund as of the date of such election. As of December 31, 20162018 and 2015,2017, there were 74,309 and 74,309 units, respectively, in the AGC SERP. See Note 19, Employee Benefit Plans.


Dividends

Any determination to pay cash dividends is at the discretion of the Company's Board, and depends upon the Company's results of operations, cash flows from operating activities, its financial position, capital requirements, general business conditions, legal, tax, regulatory, rating agency and contractual restrictions on the payment of dividends, other potential uses for such funds, and any other factors the Company's Board deems relevant. For more information concerning regulatory constraints that affect the Company's ability to pay dividends, see Note 11, Insurance Company Regulatory Requirements.

On February 22, 2017,27, 2019, the Company declared a quarterly dividend of $0.1425$0.18 per common share an increase of nearly 10% from a quarterly dividend of $0.13compared with $0.16 per common share paid in 2016.2018, an increase of 12.5%.

19.Employee Benefit Plans

Accounting Policy

Share-based compensation expense is based on the grant date fair value using the grant date closing price, the lattice, Monte Carlo or Black-Scholes-Merton (Black-Scholes) pricing models. The Company amortizes the fair value of share-based awards on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods, with the exception of retirement‑eligible employees. For retirement-eligible employees, certain awards contain retirement provisions and therefore are amortized over the period through the date the employee first becomes eligible to retire and is no longer required to provide service to earn part or all of the award.

The fair value of each award under the Assured Guaranty Ltd. Employee Stock Purchase Plan is estimated at the beginning of each offering period using the Black-Scholes option valuation model.

The expense for Performance Retention Plan awards is recognized straight-line over the requisite service period, with the exception of retirement eligible employees. For retirement eligible employees, the expense is recognized immediately.

Assured Guaranty Ltd. 2004 Long-Term Incentive Plan

Under the Assured Guaranty Ltd. 2004 Long-Term Incentive Plan, as amended (the Incentive Plan), the number of AGL common shares that may be delivered under the Incentive Plan may not exceed 18,670,000. In the event of certain transactions affecting AGL's common shares, the number or type of shares subject to the Incentive Plan, the number and type of shares subject to outstanding awards under the Incentive Plan, and the exercise price of awards under the Incentive Plan, may be adjusted.

The Incentive Plan authorizes the grant of incentive stock options, non-qualified stock options, stock appreciation rights, and full value awards that are based on AGL's common shares. The grant of full value awards may be in return for a participant's previously performed services, or in return for the participant surrendering other compensation that may be due, or may be contingent on the achievement of performance or other objectives during a specified period, or may be subject to a risk of forfeiture or other restrictions that will lapse upon the achievement of one or more goals relating to completion of service by the participant, or achievement of performance or other objectives. Awards under the Incentive Plan may accelerate and become vested upon a change in control of AGL.

The Incentive Plan is administered by the Compensation Committee of the Board, except as otherwise determined by the Board. The Board may amend or terminate the Incentive Plan. As of December 31, 2016, 10,232,6492018, 9,779,294 common shares were available for grant under the Incentive Plan.

Time Vested Stock Options

The Company uses a lattice model to value its employee and director stock options, rather than a simple Black-Scholes formula. The Black-Scholes approach is designed for options exercisable only at maturity (European style), but can still be used to value options exercisable at any time after they vest (American style) as long as no dividend payments are being made on the stock.  A lattice model can be used for both European and American style options and regardless of whether or not the stock is paying regular dividends. Because the options the Company has granted to its employees and directors are American style and because the Company pays regular dividends on its stock, the Company has selected a lattice model as the appropriate method to value thesenon-vested options.

The expected dividend yield is based on the current expected annual dividend and share price on the grant date. The expected volatility is estimated at the date of grant based on an average of the 7-year historical share price volatility and implied volatilities of certain at-the-money actively traded call options in the Company. The risk-free interest rate is the implied 7-year yield currently available on U.S. Treasury zero-coupon issues at the date of grant. The forfeiture rate is based on the historical employee termination information.

The total intrinsic value of stock options exercised during the years ended December 31, 2018, 2017 and 2016 2015was $9.9 million, $6.6 million and 2014 was $4.6 million,$2.8 million and $3.0 million, respectively. During the years ended December 31, 2018, 2017 and 2016, 2015 and 2014, $12.0$2.4 million, $4.9$4.7 million and $4.3$12.0 million, respectively, was received from the exercise of stock options. In order to satisfy stock option exercises, the Company issues new shares.

Performance Stock Options

The Company grants performance stock options under the Incentive Plan. These awards are non-qualified stock options with exercise prices equal to the closing price of an AGL common share on the applicable date of grant. These awards vest 35%, 50% or 100%, if the price of AGL's common shares using the highest 40-day average share price during the relevant three-year performance period reaches certain hurdles. If the share price is between the specified levels, the vesting level will be interpolated accordingly. These awards expire seven years from the date of grant.

Restricted Stock Awards

Restricted stock awards are valued based on the closing price of the underlying shares at the date of grant. Restricted stock awards to employees generally vest in equal annual installments over a four-year period and restricted stock awards to outside directors vest in full in one year. Restricted stock awards to employees are amortized on a straight-line basis over the requisite service periods of the awards, and restricted stock awards to outside directors are amortized over one year, which are generally the vesting periods, with the exception of retirement‑eligible employees, discussed above.

The expected dividend yield is based on the current expected annual dividend and $6 million, respectively.share price on the grant date. The expected volatility is estimated at the date of grant based on an average of the 3-year historical share price volatility and implied volatilities of certain at-the-money actively traded call options in the Company. The risk-free interest rate is the implied 3-year yield currently available on U.S. Treasury zero-coupon issues at the date of grant. The expected life is based on the 18-month term of the performance period.

Employee Stock Purchase Plan

The Company established the AGL Employee Stock Purchase Plan (Stock Purchase Plan) in accordance with Internal Revenue Code Section 423, and participation is available to all eligible employees. Maximum annual purchases by participants are limited to the number of whole shares that can be purchased by an amount equal to 10% of the participant's compensation or, if less, shares having a value of $25,000. Participants may purchase shares at a purchase price equal to 85% of the lesser of the fair market value of the stock on the first day or the last day of the subscription period. The Company has reserved for issuance and purchases under the Stock Purchase Plan 600,000 Assured Guaranty Ltd. common shares.

The fair value of each award under the Stock Purchase Plan is estimated at the beginning of each offering period using the Black‑Scholes option‑pricing model and the following assumptions: a) the expected dividend yield is based on the current expected annual dividend and share price on the grant date; b) the expected volatility is estimated at the date of grant based on

the historical share price volatility, calculated on a daily basis; c) the risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant; and d) the expected life is based on the term of the offering period.

Defined Contribution Plan

The Company maintains a savings incentive plan, which is qualified under Section 401(a) of the Internal Revenue Code for U.S. employees. The savings incentive plan is available to eligible full-time employees upon hire. Eligible participants could contribute a percentage of their salary subject to a maximum of $18,000$18,500 for 2016.2018. Contributions are matched by the Company at a rate of 100% up to 6% of participant's compensation, subject to IRS limitations. Any amounts over the IRS limits are contributed to and matched by the Company into a nonqualified supplemental executive retirement plan for employees eligible to participate in such nonqualified plan. The Company also makes a core contribution of 6% of the participant's compensation to the qualified plan, subject to IRS limitations, and the nonqualified supplemental executive retirement plan for eligible employees, regardless of whether the employee contributes to the plan(s). Employees become fully vested in Company contributions after one year of service, as defined in the plan. Plan eligibility is immediate upon hire. The Company also maintains similar non-qualified plans for non-U.S. employees.

The Company recognized defined contribution expenses of $11 million, $10 million and $11 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Cash-Based Compensation Plans

The Company maintains a Performance Retention Plan (PRP) that permits the grant of deferred cash based awards to selected employees. Generally, each PRP award is divided into three installments that vest over four years. The cash payment depends on growth in certain measures of intrinsic value and financial return defined in each PRP award agreement. The Company recognized performance retention plan expenses of $12 million, $11 million and $15$11 million for the years ended December 31, 2018, 2017 and 2016, 2015 and 2014, respectively.

Cash-Based Compensation Plans

The Company’s executive officers are eligible to receive compensation under a non-equity incentive plan. The amount of compensation payable is subject to a performance goal being met. The Compensation Committee then uses discretion to determine the actual amount of cash incentive compensation payable to each executive officer for such performance year based on factors and criteria as determined by the Compensation Committee, provided that such discretion cannot be used to increase

the amount that was determined to be payable to each executive officer. For an applicable performance year, the Compensation Committee establishes target financial performance measures for the Company and individual non-financial objectives for the executive officers. Most employees other than executive officers are eligible to receive discretionary bonuses.

ITEM 9A.CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Assured Guaranty's management, with the participation of Assured Guaranty Ltd.'sAGL's President and Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of Assured Guaranty Ltd.'sAGL's disclosure controls and procedures (as such term is defined in Rules 13a 15(e) and 15d 15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)) as of the end of the period covered by this report. Based on this evaluation, Assured Guaranty Ltd.'sAGL's President and Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, Assured Guaranty Ltd.'sAGL's disclosure controls and procedures are effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by Assured Guaranty Ltd.AGL (including its consolidated subsidiaries) in the reports that it files or submits under the Exchange Act.

There has been no change in the Company's internal controls over financial reporting during the Company's quarter ended December 31, 2016,2018, that has materially affected, or is reasonably likely to materially affect, the Company's internal controls over financial reporting.


Management's Report on Internal Control over Financial Reporting

The management of Assured Guaranty Ltd.AGL is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Internal control over financial reporting is a process designed by, or under the supervision of the Company's President and Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company's consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.GAAP.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
    
On July 1, 2016, the Company acquired CIFG Holding Inc. and its subsidiaries. See Part II, Item 8, Financial Statements and Supplementary Data, Note 2, Acquisitions, for additional information. The Company has extended its Section 404 compliance program under the Sarbanes-Oxley Act of 2002 and the applicable rules and regulations under such Act to include the integration of CIFG Holding Inc. and its subsidiaries' financial data into the Company’s existing systems, processes and related controls, as well as the new processes and controls to accommodate the business combination accounting and financial consolidation of CIFG Holding Inc. and its subsidiaries.
Management of the Company has assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 20162018 using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in the 2013 Internal Control-Integrated Framework. Based on this evaluation, management concluded that the Company's internal control over financial reporting was effective as of December 31, 20162018 based on criteria in the 2013 Internal Control- Integrated Framework issued by the COSO.

The effectiveness of the Company's internal control over financial reporting as of December 31, 20162018 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their "Report of Independent Registered Public Accounting Firm" included in Part II, Item 8, Financial Statements and Supplementary Data.
