Insurance [Abstract] |
Financial Guarantee Insurance Contracts | FINANCIAL GUARANTEE INSURANCE CONTRACTS Amounts presented in this Note relate only to Ambac’s non-derivative insurance business for insurance policies issued to beneficiaries, including VIEs, for which we do not consolidate the VIE. Net Premiums Earned: Gross premiums are received either upfront (typical of public finance obligations) or in installments (typical of structured finance obligations). For premiums received upfront, an unearned premium revenue (“UPR”) liability is established, which is initially recorded as the cash amount received. For installment premium transactions, a premium receivable asset and offsetting UPR liability is initially established in an amount equal to: (i) the present value of future contractual premiums due (the “contractual” method) or (ii) if the underlying insured obligation is a homogenous pool of assets which are contractually prepayable, the present value of premiums to be collected over the expected life of the transaction (the “expected” method). An appropriate risk-free rate corresponding to the weighted average life of each policy and currency is used to discount the future premiums contractually due or expected to be collected. For example, U.S. dollar exposures are discounted using U.S. Treasury rates while exposures denominated in a foreign currency are discounted using the appropriate risk-free rate for the respective currency. The weighted average risk-free rate at September 30, 2014 and December 31, 2013, was 2.9% and 3.0%, respectively, and the weighted average period of future premiums used to estimate the premium receivable at September 30, 2014 and December 31, 2013, was 9.5 years and 9.6 years, respectively. Insured obligations consisting of homogeneous pools for which Ambac uses expected future premiums to estimate the premium receivable and UPR include residential mortgage-backed securities. As prepayment assumptions change for homogenous pool transactions, or if there is an actual prepayment for a “contractual” method installment transaction, the related premium receivable and UPR are adjusted in equal and offsetting amounts with no immediate effect on earnings using new premium cash flows and the then current risk-free rate. Generally, the priority for the payment of financial guarantee premiums to Ambac, as required by the bond indentures of the insured obligations, is very senior in the waterfall. Additionally, in connection with the allocation of certain liabilities to the Segregated Account, trustees are required under the Segregated Account Rehabilitation Plan and related court orders to continue to pay installment premiums, notwithstanding the Segregated Account Rehabilitation Proceedings. In evaluating the credit quality of the premium receivables, management evaluates the transaction waterfall structures and the internal ratings of the transactions underlying the premium receivables. As of September 30, 2014 and December 31, 2013, approximately 44% and 44% of the premium receivables related to transactions with non-investment grade internal ratings, comprised mainly of non-investment grade RMBS, student loan transactions and a certain asset-backed transaction, which comprised 6%, 6%, and 18% of the total premium receivables at September 30, 2014 and 7%, 7% and 17% of the total premium receivables at December 31, 2013, respectively. At September 30, 2014 and December 31, 2013, $16,063 and $15,262, respectively, of premium receivables were deemed uncollectable. Past due premiums on policies insuring non-investment grade obligations amounted to less than $500 at September 30, 2014. Below is the gross premium receivable roll-forward (direct and assumed contracts) for the affected periods:
| Successor Ambac |  |  | Predecessor Ambac

Similar to gross premiums, premiums ceded to reinsurers are paid either upfront or in installments. Premiums ceded to reinsurers reduce the amount of premiums earned by Ambac from its financial guarantee insurance policies. When a bond issue insured by Ambac Assurance has been retired, including those retirements due to refundings or calls, any remaining UPR is recognized at that time to the extent the financial guarantee contract is legally extinguished, causing accelerated premium revenue. For installment premium paying transactions, the recognition of any remaining UPR is offset by the reduction of the related premium receivable to zero (as it will not be collected as a result of the retirement), which may cause negative accelerated premium revenue. Successor Ambac’s accelerated premium revenue for retired obligations for the three and nine months ended September 30, 2014 was $9,192 and $42,296. Successor Ambac’s accelerated premium revenue for retired obligations for the three and five months ended September 30, 2013 were $19,698 and $32,747. Predecessor Ambac’s accelerated premium revenue for retired obligations for the four months ended April 30, 2013 was $36,433. Certain obligations insured by Ambac have been legally defeased whereby government securities are purchased by the issuer with the proceeds of a new bond issuance, or less frequently with other funds of the issuer, and held in escrow (a pre-refunding). The principal and interest received from the escrowed securities are then used to retire the Ambac-insured obligations at a future date either to their maturity date or a specified call date. Ambac has evaluated the provisions in certain financial guarantee insurance policies issued on legally defeased obligations and determined those insurance policies have not been legally extinguished and, therefore, premium revenue recognition has not been accelerated. The effect of reinsurance on premiums written and earned was as follows:

(1) | Future premiums to be collected are undiscounted and relate to the discounted premium receivable asset recorded on Ambac's balance sheet. Future premiums to be earned, net of reinsurance relate to the unearned premium liability and deferred ceded premium asset recorded on Ambac’s balance sheet. The use of contractual lives for many bond types which do not have homogeneous pools of underlying collateral is required in the calculation of the premium receivable as described above, which results in a higher premium receivable balance than if expected lives were considered. If installment paying policies are retired or prepay early, premiums reflected in the premium receivable asset and amounts reported in the above table for such policies may not be collected in the future. Future premiums to be earned also considers the use of contractual lives for many bond types which do not have homogeneous pools of underlying collateral, which results in higher unearned premium than if expected lives were considered. If those bonds types are retired early, premium earnings may be negative in the period of call or refinancing.
Loss and Loss Expense Reserves: A loss reserve is recorded on the balance sheet on a policy-by-policy basis for: (a) unpaid claims and (b) the excess of the present value of expected net cash flows required to be paid under an insurance contract, over the unearned premium revenue for that contract. Unpaid Claims are defined as the sum of (i) claims presented and not yet paid for policies allocated to the Segregated Account, including Deferred Amounts (as defined in Note 1) and (ii) accrued interest on Deferred Amounts (generally at an effective rate of 5.1%) as required by the amended Segregated Account Rehabilitation Plan that became effective on June 12, 2014. Refer to Note 1 for further discussion of the amended Segregated Account Rehabilitation Plan. In accordance ASC Topic 944, unpaid claims are measured based on the estimated cost of settling the claims, which is principal plus accrued interest. The present value of expected net cash flows is defined as the present value of expected future claims to be paid under an insurance contract (including the impact of potential settlement outcomes upon future installment premiums) less the present value of potential future recoveries. In accordance with the financial guarantee insurance accounting guidance of ASC Topic 944, the approaches used to estimate expected future claims and expected future recoveries considers the likelihood of all possible outcomes. These estimation approaches are further described in Note 2, Basis Of Presentation And Significant Accounting Policies, in Part II, Item 8 “Financial Statements and Supplementary Data” included in Ambac’s Annual Report on Form 10-K for the year ended December 31, 2013. For those policies where the potential recovery is less than the sum of unpaid claims and expected future claims, the resulting net cash outflow is recorded as a "Loss and loss expense reserves" liability. For those policies where losses have been paid, but not yet fully recovered, the potential recovery may be greater than the unpaid claims and expected future claims, and the resulting net cash inflow is recorded as a "Subrogation recoverable" asset. Below are the components of the Loss and loss expense reserves liability and the Subrogation recoverable asset at September 30, 2014 and December 31, 2013:

The negative development in loss and loss expense reserves for Successor Ambac established in prior years for the nine months ended September 30, 2014 was primarily due to the addition of accrued interest on Deferred Amounts pursuant to the amended Segregated Account Rehabilitation Plan offset by improved performance in all sectors, including RMBS, international municipal and other structured finance. The positive development in loss and loss expense reserves for Successor Ambac established in prior years for the five months ended September 30, 2013 was primarily due to improved performance of the Student Loan and RMBS portfolios. The positive development in loss and loss expense reserves for Predecessor Ambac established in prior years for the four months ended April 30, 2013 was primarily due to improved performance of the RMBS portfolio offset by deterioration in certain Public Finance and Ambac Assurance UK Limited ("Ambac UK") credits. The net change in net loss and loss expense reserves are included in losses and loss expenses in the Consolidated Statement of Total Comprehensive Income. For Successor Ambac, reinsurance recoveries of losses included in losses and loss expenses in the Consolidated Statements of Total Comprehensive Income were an expense of $3,885 and $16,045 for the three and nine months ended September 30, 2014, respectively. Reinsurance recoveries of losses included in losses and loss expenses in the Consolidated Statements of Total Comprehensive Income were an expense of $17,418 and $12,355 for the three and five months ended September 30, 2013, respectively. For Predecessor Ambac, reinsurance recoveries of losses included in losses and loss expenses in the Consolidated Statements of Total Comprehensive Income was a benefit of $3,889 for the four months ended April 30, 2013. The tables below summarize information related to policies currently included in Ambac’s loss and loss expense reserves or subrogation recoverable at September 30, 2014 and December 31, 2013. Net par exposures include capital appreciation bonds which are reported at the par amount at the time of issuance of the insurance policy. The weighted average risk-free rate used to discount loss reserves at September 30, 2014 and December 31, 2013 was 2.7% and 3.2%, respectively.

Ambac records estimated subrogation recoveries for breaches of representations and warranties (R&W) by sponsors of certain RMBS transactions. Prior to the June 30, 2014 reporting period, Ambac utilized the Adverse and Random Sample approaches to estimate R&W subrogation recoveries for certain RMBS transactions. For a discussion of these subrogation recovery approaches, see Note 2, Basis Of Presentation And Significant Accounting Policies, in Part II, Item 8 “Financial Statements and Supplementary Data” included in Ambac’s Annual Report on Form 10-K for the year ended December 31, 2013. Beginning with the June 30, 2014 reporting period, as a result of gaining further access to loan files, the Random Sample approach has been utilized for all transactions which were previously evaluated using the Adverse Sample approach. Ambac has recorded RMBS subrogation recoveries of $2,214,430 ($2,189,967 net of reinsurance) and $2,206,598 ($2,183,652 net of reinsurance) at September 30, 2014 and December 31, 2013, respectively. The balance of RMBS subrogation recoveries and the related claim liabilities, by estimation approach, at September 30, 2014 and December 31, 2013, are as follows:
|  | September 30, 2014
Approach |  | Gross loss reserves before subrogation recoveries (1) |  | Subrogation recoveries (2)(3) |  | Gross loss reserves after subrogation recoveries
Random samples (4) |  | $ | 2,670,550 |  |  | $ | (2,214,430 | ) |  | $ | 456,120 |
Totals |  | $ | 2,670,550 |  |  | (2,214,430 | ) |  | $ | 456,120 |
|  | December 31, 2013
Approach |  | Gross loss reserves before subrogation recoveries (1) |  | Subrogation recoveries (2) (3) |  | Gross loss reserves after subrogation recoveries
Adverse samples |  | $ | 2,084,911 |  |  | (1,252,773 | ) |  | $ | 832,138 |
Random samples (4) |  | 1,078,861 |  |  | (953,825 | ) |  | 125,036 |
Totals |  | $ | 3,163,772 |  |  | (2,206,598 | ) |  | $ | 957,174 |
(1) | Includes unpaid RMBS claims, including accrued interest on Deferred Amounts, on policies allocated to the Segregated Account.
(2) | The amount of recorded subrogation recoveries related to each securitization is limited to ever-to-date paid and unpaid losses plus the present value of expected cash flows for each policy. To the extent losses have been paid but not yet fully recovered, the recorded amount of RMBS subrogation recoveries may exceed the sum of the unpaid claims and the present value of expected cash flows for a given policy. The net cash inflow for these policies is recorded as a “Subrogation recoverable” asset. For those transactions where the subrogation recovery is less than the sum of unpaid claims and the present value of expected cash flows, the net cash outflow for these policies is recorded as a “Loss and loss expense reserves” liability.
(3) | The sponsor’s repurchase obligation may differ depending on the terms of the particular transaction and the status of the specific loan, such as whether it is performing or has been liquidated or charged off. The estimated subrogation recovery for these transactions is based primarily on loan level data provided through trustee reports received in the normal course of our surveillance activities or provided by the sponsor. While this data may not include all the components of the sponsor’s contractual repurchase obligation we believe it is the best information available to estimate the subrogation recovery.
(4) | From time to time R&W subrogation may include estimates of potential sponsor settlements that are currently in negotiation but have not been subject to a sampling approach. However, such estimates are not material to Ambac’s financial results and therefore are included in the Random Sample section of this table.

(1) | Represents estimated subrogation for those transactions previously evaluated using the Adverse Sample approach, which are evaluated using a Random Sample approach beginning June 30, 2014. The amounts shown in the Random and Adverse Sample columns are different as a result of the differences in estimation approaches.
(2) | Sponsor actions include loan repurchases, direct payments to Ambac, and other contributions from sponsors.
(3) | All other changes which may impact RMBS subrogation recoveries include changes in actual or projected collateral performance, changes in the creditworthiness of a sponsor, and/or the projected timing of recoveries. All other changes may also include estimates of potential sponsor settlements that are currently in negotiation but have not been subject to a sampling approach. However, such estimates are not material to Ambac’s financial results and therefore are included in the Random Sample column of this table.
