Expected Losses [Abstract]  
Expected Loss to be Paid
Expected Loss to be Paid
 
This note provides information regarding expected claim payments to be made under all contracts in the insured portfolio, regardless of the accounting model (insurance, derivative or VIE). The expected loss to be paid is equal to the present value of expected future cash outflows for claim and loss adjustment expenses (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 underlying collateral, and other estimated recoveries, including those from restructuring bonds and for breaches of representations and warranties (R&W)), using current risk-free rates.

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, 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, 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 loss 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 life of most contracts.

The Company does not use traditional actuarial approaches to determine its estimates of expected losses. 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.

In some instances, the terms of the Company's policy give 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 net expected loss to be paid for all contracts. The Company used risk-free rates for U.S. dollar denominated obligations that ranged from 0.00% to 2.20% with a weighted average of 1.79% as of September 30, 2019 and 0.00% to 3.06% with a weighted average of 2.74% as of December 31, 2018. Expected losses to be paid for transactions denominated in currencies other than the U.S. dollar represented approximately 4.0% and 2.7% of the total as of September 30, 2019 and December 31, 2018, respectively.

Net of ceded paid losses, whether or not such amounts have been settled with reinsurers. Ceded paid losses are typically settled 45 days after the end of the reporting period. Such amounts are recorded as reinsurance recoverable on paid losses in other assets. The amounts for Nine Months 2019 are net of the COFINA Exchange Senior Bonds and cash that were received pursuant to the COFINA Plan of Adjustment. See Note 3, Outstanding Exposure, for additional information.

The tables above include (1) LAE paid of $7 million and $6 million for Third Quarter 2019 and 2018, respectively, and $23 million and $17 million for Nine Months 2019 and 2018, respectively, and (2) expected LAE to be paid of $34 million as of September 30, 2019 and $31 million as of December 31, 2018.

Selected U.S. Public Finance Transactions
 
The Company insured general obligation bonds of the Commonwealth of Puerto Rico and various obligations of its related authorities and public corporations aggregating $4.3 billion net par as of September 30, 2019, all of which was BIG. For additional information regarding the Company's Puerto Rico exposure, see "Exposure to Puerto Rico" in Note 3, Outstanding Exposure.

As of December 31, 2018, the Company had approximately $18 million of net par exposure to bonds issued by Parkway East Public Improvement District (District), which is located in Madison County, Mississippi. The bonds were rated BIG. As part of a settlement with the County, during Third Quarter 2019 the bonds were paid off, reducing the Company's net par exposure to zero, and the Company received new bonds issued by the District, which the Company holds in its investment portfolio.

On February 25, 2015, a plan of adjustment resolving the bankruptcy filing of the City of Stockton, California under chapter 9 of the Bankruptcy Code became effective. As of September 30, 2019, the Company’s net par subject to the plan consisted of $107 million of pension obligation bonds. As part of the plan 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 its total net expected loss across its troubled U.S. public finance exposures as of September 30, 2019, including those mentioned above, to be $520 million, compared with a net expected loss of $832 million as of December 31, 2018. 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 September 30, 2019 that credit was $842 million compared with $586 million at December 31, 2018. The Company’s net expected losses incorporate management’s probability weighted estimates of possible scenarios. Each quarter, the Company may revise its scenarios, update assumptions and/or shift probability weightings of its scenarios based on public information as well as nonpublic information obtained through its surveillance and loss mitigation activities. Management assesses the possible implications of such information on each insured obligation, considering the unique characteristics of each transaction.

The economic loss development for U.S. public finance transactions was $50 million during Third Quarter 2019 and $204 million during Nine Months 2019, which was primarily attributable to Puerto Rico exposures. The loss development attributable to the Company’s Puerto Rico exposures reflects adjustments the Company made to the assumptions and weightings it uses in its scenarios based on the public information summarized under "Exposure to Puerto Rico" in Note 3, Outstanding Exposure as well as nonpublic information related to its loss mitigation activities during the periods presented.

Selected Non - U.S. Public Finance Transactions
    
Expected loss to be paid for non-U.S. public finance transactions was $28 million as of September 30, 2019, compared with $32 million as of December 31, 2018, primarily consisting of: (i) an obligation backed by payments from a region in Italy, and for which the Company has been paying claims because of the impact of negative Euro Interbank Offered Rate (Euribor) on the transaction, (ii) transactions 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, and (iii) an obligation backed by the availability and toll revenues of a major arterial road into a city in the U.K., which has been underperforming due to higher costs compared with expectations at underwriting.

The economic loss development for non-U.S. public finance transactions, including those mentioned above was approximately $5 million during Third Quarter 2019 due to the impact of negative European interest rates on an interest rate swap in an Italian transaction. The economic benefit was $4 million during Nine Months 2019, which was mainly attributable to the improved internal outlook of certain Spanish sovereigns and sub-sovereigns, and partially offset by the impact of negative European interest rates on an interest rate swap in an Italian transaction.

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 recoveries/payables to the projected performance of the collateral over time. The resulting projected claim payments or reimbursements are then discounted using risk-free rates.

As of September 30, 2019, the Company had a net R&W payable of $60 million to R&W counterparties, compared with a net R&W receivable of $5 million as of December 31, 2018. 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.

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. The assumptions that the Company uses to project RMBS losses are shown in the sections below.

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 conditional default rate (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), 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 3.75 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 had reached historically high levels, and the Company is assuming in the base case that the still elevated levels generally will continue for another 18 months. The Company determines its initial loss severity based on actual recent experience. Each quarter the Company reviews available data and (if necessary) adjusts its severities based on 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 vintage 2004 - 2008 first lien U.S. RMBS.

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 June 30, 2019 and December 31, 2018.
 
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 September 30, 2019 and December 31, 2018.
    
Total expected loss to be paid on all first lien U.S. RMBS was $164 million and $243 million as of September 30, 2019 and December 31, 2018, respectively. The $27 million economic benefit in Third Quarter 2019 and $77 million economic benefit in Nine Months 2019 for first lien U.S. RMBS was primarily attributable to higher excess spread on certain transactions supported by large portions of fixed rate assets (either originally fixed or modified to be fixed) and with insured floating rate debt linked to London Interbank Offered Rate (LIBOR), which decreased in Third Quarter 2019 and Nine Months 2019. The Company used a similar approach to establish its pessimistic and optimistic scenarios as of September 30, 2019 as it used as of December 31, 2018, increasing and decreasing the periods of stress from those used in the base case. LIBOR may be discontinued, and it is not yet clear how this will impact the calculation of the various interest rates in this portfolio referencing LIBOR.

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, expected loss to be paid would increase from current projections by approximately $49 million for all first lien 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 $44 million for all first lien 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 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, the CPR of the collateral, the interest rate environment and assumptions about 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. 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 plateau 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, representing six months of delinquent loan liquidations, followed by 28 months of decrease to the steady state CDR, the same as of December 31, 2018.

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. This causes the borrower's total monthly payment to increase, sometimes substantially, at the end of the initial interest-only period. In prior periods, as the HELOC loans underlying the Company's insured HELOC transactions reached their principal amortization period, the Company incorporated an assumption that a percentage of loans reaching their principal amortization periods would default around the time of the payment increase.

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, the Company does not apply a CDR increase when such loans reach their principal amortization period. In addition, based on the average performance history, the Company applies 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 low recovery. The Company assumed, as of September 30, 2019 and December 31, 2018, that it will generally recover 2% of future defaulting collateral at the time of charge-off, with additional amounts of post charge-off recoveries projected to come in over time. 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. The Company evaluates its assumptions periodically based on actual recoveries of charged-off loans observed from period to period. In instances where the Company is able to obtain information on the lien status of charged-off loans, it assumes there will be a certain level of future recoveries of the balance of the charged-off loans where the second lien is still intact. The Company projected future recoveries on these charged off loans of 20% as of September 30, 2019 and 10% as of December 31, 2018, with such recoveries to be received evenly over the next five years. The increase in recovery assumptions is attributable to the higher actual recovery rates observed in certain transactions during the year. Increasing the recovery rate to 30% would result in an economic benefit of $61 million, while decreasing the recovery rate back to 10% would result in an economic loss of $61 million
 
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 consistent with how the Company modeled the CPR as of June 30, 2019 and December 31, 2018. To the extent that prepayments differ from projected levels it could materially change the Company’s projected excess spread and losses.
 
In estimating expected losses, the Company modeled and probability weighted five scenarios, each with a different CDR curve applicable to the period preceding the return to the long-term steady state CDR. The Company believes that the level of the elevated CDR and the length of time it will persist and the ultimate prepayment rate are the primary drivers behind the amount of losses the collateral will likely 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 recovery on all second lien U.S. RMBS was $29 million as of September 30, 2019 and the expected loss to be paid was $50 million as of December 31, 2018. The economic benefit for second lien U.S. RMBS was $13 million in Third Quarter 2019, primarily attributable to improved performance of underlying collateral, and $146 million in Nine Months 2019, primarily attributable to higher projected recoveries for previously charged-off loans and improved performance of underlying collateral.

(1)    Loss severities on future defaults.

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. In 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) would increase the expected loss by approximately $6 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 $7 million for HELOC transactions.

Other Structured Finance
 
The Company projected that its total net expected loss across its troubled other structured finance exposures as of September 30, 2019 was $35 million and is primarily attributable to $87 million in BIG net par of student loan securitizations issued by private issuers that are classified as structured finance. In general, the projected losses of these transactions 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 Company also had exposure to troubled life insurance transactions. As of September 30, 2019, the Company's BIG net par in these transactions was $40 million, which was lower than the $85 million as of December 31, 2018 because of the settlement of a transaction.

The economic loss development during Third Quarter 2019 and Nine Months 2019 was $10 million and $9 million, which was primarily attributable to higher expected LAE related to certain exposures.

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

The Company has asserted claims in a number of legal proceedings in connection with its exposure to Puerto Rico. See Note 3, Outstanding Exposure, for a discussion of the Company's exposure to Puerto Rico and related recovery litigation being pursued by the Company.

RMBS Transactions

On November 26, 2012, CIFG Assurance North America Inc. (CIFGNA) filed a complaint in the Supreme Court of the State of New York against JP Morgan Securities LLC for material misrepresentation in the inducement of insurance and common law fraud, alleging that JP Morgan Securities LLC 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 court 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 court 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’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’s decision dismissing with prejudice CIFGNA’s material misrepresentation in the inducement of insurance claim should be modified to grant CIFGNA leave to re-plead such claim. On February 27, 2017, AGC (as successor to CIFGNA) filed an amended complaint which included a claim for material misrepresentation in the inducement of insurance. On July 31, 2019, the parties entered into a confidential settlement and, on August 12, 2019, agreed to dismiss, with prejudice, the action and all claims.
