Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation and Significant Accounting Policies | Basis of Presentation The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). In management’s opinion, all material adjustments necessary for a fair statement of the financial condition, results of operations and cash flows of the Company, including its consolidated variable interest entities (VIEs), are reflected in the periods 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. Certain prior year balances have been reclassified to conform to the current year’s presentation. Significant Accounting Policies The Company revalues foreign currency denominated assets, liabilities, revenue, and expenses, into U.S. dollars using the applicable exchange rates prescribed by GAAP. For subsidiaries where the functional currency is the U.S. dollar, gains and losses generated by the remeasurement of foreign currency transactions are reported in the consolidated statements of operations. For consolidated entities whose functional currency is not the U.S. dollar amounts generated by translating foreign currency financial statements to the Company’s U.S. dollar reporting currency, are reported in the consolidated statements of comprehensive income (loss). Other accounting policies are included in the following notes to the consolidated financial statements.

Consolidation | The consolidated financial statements include the accounts of AGL, its direct and indirect subsidiaries, and its consolidated financial guaranty VIEs (FG VIEs) and CIVs. See Note 8, Financial Guaranty Variable Interest Entities and Consolidated Investment Vehicles. Intercompany accounts and transactions between and among all consolidated entities have been eliminated. All amounts are reported in U.S. dollars, unless otherwise specified.
Foreign Currency Transactions and Translations | The Company revalues foreign currency denominated assets, liabilities, revenue, and expenses, into U.S. dollars using the applicable exchange rates prescribed by GAAP. For subsidiaries where the functional currency is the U.S. dollar, gains and losses generated by the remeasurement of foreign currency transactions are reported in the consolidated statements of operations. For consolidated entities whose functional currency is not the U.S. dollar amounts generated by translating foreign currency financial statements to the Company’s U.S. dollar reporting currency, are reported in the consolidated statements of comprehensive income (loss).
Recent Accounting Standards Adopted and Not Yet Adopted | Recent Accounting Standards Adopted Targeted Improvements to the Accounting for Long-Duration Contracts In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts. The Company’s adoption of this ASU on January 1, 2023 did not have any effect on the Company’s consolidated financial statements. Recent Accounting Standards Not Yet Adopted In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments in this ASU enhance disclosures by requiring that the Company disclose significant segment expenses regularly provided to the chief operating decision maker (CODM), extend certain annual disclosures to interim periods, and permit more than one measure of segment profit or loss to be reported under certain conditions. This ASU is effective in fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, including adoption in any interim periods for which financial statements have not been issued. The Company will apply the amendments in this ASU retrospectively to all prior periods presented in its consolidated financial statements. The Company is evaluating the effect that the adoption of this ASU may have on its disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments require enhanced annual disclosures regarding the rate reconciliation and income taxes paid. This ASU is effective for fiscal years beginning after December 15, 2024. The Company will apply the amendments in this ASU prospectively to all annual periods beginning after December 15, 2024. The Company is evaluating the effect that the adoption of this ASU may have on its disclosures.
Segment Information | The Company reports its results of operations in two segments: Insurance and Asset Management. The Company also reports the results of its Corporate division and the effects of consolidating FG VIEs and CIVs. This presentation is consistent with the manner in which the Company’s CODM reviews the business to assess performance and allocate resources.
Expected Loss to be Paid | Net expected loss to be paid (recovered) is equal to the present value of expected future cash outflows for loss and LAE payments, net of: (i) inflows for expected salvage, subrogation and other recoveries; (ii) excess spread on underlying collateral, as applicable, and (iii) amounts ceded to reinsurers. Cash flows are discounted at current risk-free rates. The Company updates the discount rates 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 management’s assumptions about the likelihood of all possible outcomes based on all information available to the Company. Those assumptions consider the relevant facts and circumstances and are consistent with the information tracked and monitored through the Company’s surveillance and risk-management functions. Expected loss to be paid (recovered) is important in that it represents the present value of amounts that the Company expects to pay or recover in future periods for all contracts.
Premiums | Financial guaranty contracts that meet the scope exception under derivative accounting guidance are subject to industry specific accounting guidance for financial guaranty insurance. Premiums receivable represent the present value of contractual or expected future premium collections, discounted using risk-free rates. Unearned premium reserve represents deferred premium revenue less claim payments made (net of recoveries received) that have not yet been recognized in the statement of operations (i.e., 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 “Losses and Recoveries.” 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 calculated as the present value (discounted at risk free rates) of either: (i) contractual premiums due; or (ii) in cases where the underlying collateral is composed 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 allowable, the amount of prepayments must be probable, and the timing and amount of prepayments must be reasonably estimable. Installment premiums typically relate to structured finance (e.g., securitized debt) and infrastructure 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 (not the discounted future cash flows under the insurance contract). The amount of deferred premium revenue may differ significantly from cash collections primarily due to fair value adjustments recorded in connection with a business combination. When the Company adjusts prepayment assumptions for expected premium collections for obligations backed by homogeneous pools of contractually prepayable assets, an adjustment is recorded to the deferred premium revenue, with a corresponding adjustment to premiums 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. Accretion of the discount on premiums receivable is reported in “net earned premiums”. 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 par 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 par amounts outstanding in the reporting period compared with the sum of each of the insured par amounts outstanding for all periods. When an insured financial obligation is retired before its maturity, the financial guaranty insurance contract is extinguished, and any nonrefundable deferred premium revenue related to that contract is accelerated and recognized as premium revenue. Any unamortized acquisition costs are expensed. The Company assesses the need for an allowance for credit loss on premiums receivables each reporting period. For assumed reinsurance contracts, net earned premiums reported in the consolidated statements of operations are calculated based upon data received from ceding 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 contracts, the Company assesses the credit quality and available liquidity of the ceding companies and the impact of any potential regulatory constraints to determine the collectability of such amounts.
Policy Acquisition Costs | DAC is generally 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 expensed at that time. Costs incurred for soliciting potential customers, market research, training, administration, unsuccessful acquisition efforts, and product development as well as overhead costs are charged to expense as incurred. 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.
Loss and LAE Reserve | 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 portion of any contract’s reserve that is ceded to a reinsurer is reported as reinsurance recoverable on unpaid losses and reported in other assets. Any loss and LAE reserves related to FG VIEs are eliminated upon consolidation. Any expected losses to be paid (recovered) on credit derivatives are reflected in the fair value of credit derivatives. Under financial guaranty insurance accounting, the sum of unearned premium reserve and loss and LAE reserve represents the Company’s stand‑ready obligation. A loss and LAE reserve for a financial guaranty insurance contract is recorded only to the extent, and for the amount, that expected loss to be paid plus 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, the Company first reduces any recorded loss and LAE reserve. To the extent there is insufficient 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 “loss and loss adjustment expenses (benefit)” 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 loss adjustment expenses (benefit)” in the consolidated statement of operations is presented net of cessions to reinsurers.
Salvage and Subrogation Recoverable | Salvage and Subrogation Recoverable Expected losses to be paid are reduced when a claim payment (or estimated future claim payment) entitles the Company to cash flows associated with salvage and subrogation rights from the underlying collateral of, or other recoveries relating to an insured exposure. Such reduction in expected loss to be paid can result in one of the following: (i) a reduction in the corresponding loss and LAE reserve with a benefit to the consolidated statement of operations; (ii) no effect on the consolidated balance sheet or statements of operations, if total loss is not in excess of deferred premium revenue; or (iii) the recording of a salvage asset with a benefit to the consolidated statements of operations if the transaction is in a net recovery position at the reporting date. The ceded component of salvage and subrogation recoverable is reported in “other liabilities.”
Expected Loss to be Expensed | Expected Loss to be Expensed Expected loss to be expensed represents past or expected future financial guaranty insurance net claim payments that have not yet been expensed. Such amounts will be expensed in future periods as deferred premium revenue amortizes into income. Expected loss to be expensed is the Company’s projection of incurred losses that will be recognized in future periods, excluding accretion of discount.
Contracts Accounted for as Credit Derivatives | Credit derivatives are recorded at fair value, and changes in fair value are reported in “Fair value gains (losses) on credit derivatives” in the consolidated statement of operations. The fair value of credit derivatives is determined on a contract-by-contract basis and presented as either a credit derivative assets reported in “other assets” or “credit derivative liabilities” in the consolidated balance sheets.
Investments and Cash | All fixed-maturity securities are reported on a trade date-basis, measured at fair value and classified as either trading or available-for-sale. Changes in fair value on trading fixed-maturity securities are reported as a component of net income, while unrealized gains and losses on available-for-sale fixed-maturity securities are reported in accumulated other comprehensive income (AOCI). Loss Mitigation Securities, which are a component of available-for-sale fixed-maturity securities, are accounted for based on their underlying investment type, excluding the effects of the Company’s insurance. Short-term investments, which are investments with a maturity of less than one year at the time of purchase, are carried at fair value and include amounts deposited in certain money market funds. Other invested assets primarily consist of equity method investments; the Sound Point investment being the most significant. The Company reports its interest in the earnings of equity method investments in “equity in earnings (losses) of investees” in the consolidated statement of operations. Most equity method investments are reported on a one-quarter lag. At the time of acquisition, the difference between the Company’s cost of an equity method investment (fair value) and the Company’s proportionate share of the carrying value of the investee’s net assets is referred to as the basis difference. The basis difference includes amounts attributed to finite-lived intangible assets, which are amortized over the assets’ remaining useful life, and is reported in “equity in earnings (losses) of investees.” The Company classifies distributions received from equity method investments using the cumulative earnings approach in the consolidated statements of cash flows. Under the cumulative earnings approach, distributions received up to the amount of cumulative equity in earnings recognized are treated as returns on investment within operating cash flows, and those in excess of that amount are treated as returns of investment within investing cash flows. Sound Point managed funds (and prior to July 1, 2023, AssuredIM managed funds), in which the Company invests (primarily through its investment subsidiary, AGAS), and where the Company has been deemed to be the primary beneficiary, are not reported in “investments” on the consolidated balance sheets, but rather, reported in “assets of consolidated investment vehicles” and “liabilities of consolidated investment vehicles,” with the portion not owned by the Company presented as nonredeemable noncontrolling interests (NCI). See Note 8, Financial Guaranty Variable Interest Entities and Consolidated Investment Vehicles, for further information regarding the CIVs. Cash consists of cash on hand and demand deposits. See Note 8, Financial Guaranty Variable Interest Entities and Consolidated Investment Vehicles, for cash and cash equivalents for consolidated VIEs. Net investment income primarily includes the income earned on fixed-maturity securities and short-term investments, including amortization of premiums and accretion of discounts. For mortgage-backed securities and any other securities for which there is prepayment risk, prepayment assumptions are evaluated quarterly and revised as necessary. For securities other than purchased credit deteriorated (PCD) securities, any necessary adjustments due to changes in effective yields and expected maturities are recognized in net investment income using the retrospective method. PCD securities are defined as financial assets that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination. Realized gains and losses on sales of available-for-sale fixed-maturity securities and credit losses are reported in the consolidated statement of operations. Net realized investment gains (losses) include sales of investments, which are determined using the specific identification method, reductions to amortized cost of available-for-sale investments that have been written down due to the Company’s intent to sell them or it being more-likely-than-not that the Company will be required to sell them, and the change in allowance for credit losses (including accretion) as discussed below. For all fixed-maturity securities that were originally purchased with credit deterioration, accrued interest is not separately presented, but rather is a component of the amortized cost of the instrument. For all other available-for-sale securities, a separate amount for accrued interest is reported in “other assets”.
Credit Losses | Credit Losses For an available-for-sale fixed-maturity security that has experienced a decline in fair value below its amortized cost due to credit related factors, an allowance is established for the difference between the estimated recoverable value and amortized cost with a corresponding charge to net realized investment gains (losses) in the consolidated statement of operations. The estimated recoverable value is the present value of cash flows expected to be collected. The allowance for credit losses is limited to the difference between amortized cost and fair value. Any difference between the security’s fair value and its amortized cost that is not associated with credit related factors is presented as a component of AOCI. When estimating future cash flows for fixed-maturity securities, management considers the historical performance of underlying assets and available market information as well as bond-specific considerations. In addition, the process of estimating future cash flows includes, but is not limited to, the following critical inputs, which vary by security type: •the extent to which fair value is less than amortized cost; •credit ratings; •any adverse conditions specifically related to the security, industry, and/or geographic area; •changes in the financial condition of the issuer, or underlying loan obligors; •general economic and political factors; •remaining payment terms of the security; •prepayment speeds; •expected defaults; and •the value of any embedded credit enhancements. The assessment of whether a credit loss exists is performed each reporting period. The allowance for credit losses and the corresponding charge to net realized investment gains (losses) may be reversed if conditions change. However, the allowance for credit losses is never reduced below zero. When the Company determines that all or a portion of a fixed-maturity security is uncollectible, the uncollectible amortized cost amount is written off with a corresponding reduction to the allowance for credit losses. If cash flows that were previously written off are collected, the recovery is recognized in net realized investment gains (losses). An allowance for credit losses is established upon initial recognition for available-for-sale PCD securities. On the date of acquisition, the amortized cost of PCD securities is equal to the purchase price plus the allowance for credit losses, with no credit loss expense recognized in the consolidated statements of operations. After the date of acquisition, deterioration (or improvement) in credit will result in an increase (or decrease) to the allowance and an offsetting credit loss expense (or benefit). To measure this, the Company performs a discounted cash flow analysis. For PCD securities that are also beneficial interests, favorable or adverse changes in expected cash flows are recognized as a change in the allowance for credit losses. Changes in expected cash flows that are not captured through the allowance are reflected as a prospective adjustment to the security’s yield within net investment income. The Company has elected to not measure credit losses on its accrued interest receivable and instead write off accrued interest when it is six months past due or on the date it is deemed uncollectible, if earlier. All write-offs of accrued interest are recorded as a reduction to net investment income in the consolidated statements of operations. For impaired securities that (i) the Company intends to sell, or (ii) it is more-likely-than-not that the Company will be required to sell before recovering its amortized cost, the amortized cost is written down to fair value with a corresponding charge to net realized investment gains (losses). No allowance is established in these situations and any previously recorded allowance is reversed. The new cost basis is not adjusted for subsequent increases in estimated fair value. The Company monitors its equity method investments for indicators of other-than-temporary declines in fair value on an ongoing basis. If such a decline occurs, an impairment charge is recorded, measured as the difference between the carrying value and the estimated fair value.
Variable Interest Entities | The types of entities that the Company assesses for consolidation principally include: (i) financial guaranty variable interest entities; which include entities whose debt obligations the insurance subsidiaries insure in its financial guaranty business, and Puerto Rico Trusts, and (ii) investment vehicles in which the Company has a variable interest and which Sound Point manages, including (1) Sound Point funds since July 1, 2023 and (2) CLOs that are collateralized financing entities (CFEs), and CLO warehouses managed by AssuredIM prior to July 1, 2023. For each of these types of entities, the Company first determines whether the entity is a VIE or a voting interest entity (VOE) which involves assessing, amongst other conditions, (i) whether the equity investment at risk is sufficient to cover the entity’s expected losses and (ii) whether the holders of the equity investment at risk (as a group) have substantive voting rights. The Company reassesses whether an entity is a VIE upon the occurrence of certain significant events. If the entity being evaluated for consolidation is not initially determined to be a VIE (or, later, if a significant event occurs that causes an entity to no longer qualify as a VIE), then the entity is a VOE. Consolidation generally is required when the Company, directly or indirectly, has a controlling financial interest of the VOE being assessed. For entities determined to be a VIE, and in which the Company has a variable interest, the Company assesses whether it is the primary beneficiary of the VIE at the time it becomes involved with the entity and performs this assessment quarterly. In determining whether it is the primary beneficiary, the Company considers all facts and circumstances, including an evaluation of economic interests in the VIE held directly and indirectly through related parties. The Company is the primary beneficiary of a VIE when it has both: (i) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance; and (ii) the obligation to absorb losses (or the right to receive benefits) from the entity that could potentially be significant to the VIE. If the Company concludes that it is the primary beneficiary of the VIE, it consolidates the VIE in the Company’s consolidated financial statements. If, as part of its continual reassessment of the primary beneficiary determination, the Company concludes that it is no longer the primary beneficiary of a VIE, the Company deconsolidates the VIE and recognizes the impact of that change on the consolidated financial statements. FG VIEs For FG VIEs other than the Puerto Rico Trusts, the Company elected the fair value option (FVO) for all assets and liabilities. Upon initial adoption of the accounting guidance for VIEs in 2010, the Company elected to fair value its structured finance and other FG VIEs’ assets and liabilities as the carrying amount transition method was not practical. To allow for consistency in the accounting for the assets and liabilities of its consolidated FG VIEs other than the Puerto Rico Trusts, the Company elected the FVO. The consolidated Puerto Rico Trusts described below primarily include (i) cash or fixed-maturity debt securities that are carried at fair value and classified as either available-for-sale or trading securities similar to the fixed-maturity debt securities received pursuant to the 2022 Puerto Rico Resolutions and reported in the investment portfolio, and (ii) Puerto Rico Trust liabilities for which the Company elected the FVO in order to more closely mirror the fair value measurement of the Puerto Rico Trust liabilities to the fair value measurement of the Puerto Rico Trust assets. The change in fair value of FG VIEs’ assets and liabilities is reported in “fair value gains (losses) on FG VIEs” in the consolidated statement of operations, except for (i) the change in fair value attributable to change in instrument-specific credit risk (ISCR) on FG VIEs’ liabilities, and (ii) unrealized gains and losses on the New Recovery Bonds in the Puerto Rico Trusts, which are both reported in other comprehensive income (OCI). Interest income and interest expense are derived from the trustee reports and also included in “fair value gains (losses) on FG VIEs.” Investment income on the New Recovery Bonds and changes in fair value on the CVIs in the Puerto Rico Trusts are all reported in “fair value gains (losses) on FG VIEs” on the consolidated statement of operations, as applicable. For those FG VIE liabilities with recourse to the Company, the portion of the inception-to-date change in fair value, attributable to 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 spread widens, less value is assigned to the Company’s credit. The Company has limited contractual rights to obtain the financial records of its consolidated structured finance and other FG VIEs. The structured finance and other FG VIEs do not prepare separate GAAP financial statements; therefore, the Company compiles the FG VIE GAAP financial information based on trustee reports prepared by and received from third parties. Such trustee reports are not available to the Company in time for quarterly reporting and therefore FG VIEs other than the Puerto Rico Trusts are reported on a one quarter lag. As a result of the lag, cash and short-term investments do not reflect cash outflows (due to claim payments made by the Company) to the holders of the FG VIEs’ debt until the subsequent reporting period. The cash flows generated by the FG VIEs’ assets, except for interest income, are classified as cash flows from investing activities. Paydowns of FG VIEs’ liabilities are supported by the cash flows generated by FG VIEs’ assets and, for liabilities with recourse, possibly claim payments made by AGM or AGC under their financial guaranty insurance contracts. Paydowns of FG VIEs’ liabilities both with and without recourse are classified as cash flows used in financing activities. Interest income, interest expense and other expenses of the FG VIEs’ assets and liabilities are classified as operating cash flows. Claim payments made by AGM and AGC under the financial guaranty contracts issued to the FG VIEs are eliminated upon consolidation. Therefore, such claim payments are treated as paydowns of the FG VIEs’ liabilities and as a financing activity as opposed to an operating activity. The Company’s exposure provided through its financial guaranties with respect to debt obligations of FG VIEs is included within net par outstanding in Note 3, Outstanding Exposure. CIVs CIVs consist of certain Sound Point (and prior to July 1, 2023, AssuredIM) funds, CLOs and CLO warehouses in which the Company is the primary beneficiary. The consolidated funds are investment companies for accounting purposes and therefore account for their underlying investments at fair value. All CLOs and CLO warehouses (collectively, the consolidated CLOs) were deconsolidated by the Company on July 1, 2023. The consolidated CLOs were CFEs and, therefore, the debt issued by, and loan assets held by, the consolidated CLOs were measured under the FVO using the CFE practical expedient. The assets and liabilities of consolidated CLO warehouses were also reported at fair value under the FVO election. Changes in the fair value of assets and liabilities of CIVs, interest income and interest expense are reported in “fair value gains (losses) on consolidated investment vehicles” in the consolidated statements of operations. Interest income from CLO assets is recorded based on contractual rates. All CIVs are reported on a quarter lag. Upon consolidation of a Sound Point (and prior to July 1, 2023, AssuredIM) fund, the Company records NCI for the portion of each fund owned by employees and any third-party investors. Investment transactions in the consolidated Sound Point (and prior to July 1, 2023, AssuredIM) funds are recorded on a trade/contract date basis. Money market investments held by these consolidated funds are classified as cash equivalents and carried at cost, consistent with those funds’ separately issued financial statements. Therefore, the Company has included these amounts in the total amount of cash and cash equivalents on the consolidated statements of cash flows. Cash flows of the CIVs attributable to such entities’ investment purchases and dispositions, as well as operating expenses of the investment vehicles, are presented as cash flows from operating activities in the consolidated statements of cash flows. Borrowings under credit facilities, debt issuances and repayments, and capital cash flows to and from investors are presented as financing activities, consistent with investment company guidelines. As part of the terms of its financial guaranty contracts, the insurance subsidiaries obtain certain protective rights with respect to the VIE that give them 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’s or collateral manager’s financial condition. At deal inception, the insurance subsidiaries typically are not deemed to control the VIE; however, once a trigger event occurs, the insurance subsidiaries’ 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 insurance subsidiaries and, accordingly, where they are obligated to absorb VIE losses or receive benefits that could potentially be significant to the VIE. The insurance subsidiaries are deemed to be the control party for certain VIEs under GAAP, typically when their protective rights give them the power to both terminate and replace the transaction’s servicer or collateral manager, which are characteristics specific to the Company’s financial guaranty contracts. If the protective rights that could make the insurance subsidiaries the control party have not been triggered, then the VIE is not consolidated. If the insurance subsidiaries are deemed to no longer have those protective rights, the VIE is deconsolidated. The structured finance and other FG VIEs’ liabilities that are guaranteed by the insurance subsidiaries are considered to be with recourse, because the insurance subsidiaries guarantee the payment of principal and interest regardless of the performance of the related FG VIEs’ assets. The structured finance and other FG VIEs’ liabilities that are not guaranteed by the insurance subsidiaries 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’ assets.
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 or transfer 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 (i) 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 (ii) discounted cash flows, using a third party’s proprietary pricing models. In addition to market information, when applicable, the models also incorporate transaction details, such as the instrument’s maturity, and contractual features that reduce the Company’s credit exposure (e.g., collateral rights). 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 transparency for certain products changes, the Company may refine its methodologies and assumptions. During 2023, 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 valuation methods produce fair values that may not be indicative of net realizable value or future fair values. The use of different methodologies or assumptions to determine fair value of certain financial instruments could result in a materially 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, with Level 1 being the highest and Level 3 the lowest. The categorization, of an asset or liability, within the hierarchy 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 (i) determined using pricing models, discounted cash flow methodologies or similar techniques and (ii) 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.
Asset Management Fees | All management, CLO and performance fees earned by the Company are accounted for as contracts with customers. The Company recognizes revenue when the contractual performance criteria are met and only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized would not occur when the uncertainty associated with the variable consideration is resolved. Given the uniqueness of each fee arrangement, performance fee contractual provisions were evaluated on an individual basis to determine the timing of revenue recognition.
Goodwill and Intangible Assets | Goodwill represents the excess of cost over the net fair value of assets and liabilities at the date of acquisition. Finite-lived intangible assets are recorded at fair value on the date of acquisition and are amortized over their estimated useful lives.
Long-Term Debt and Credit Facilities | Long-term debt is recorded at principal amounts net of any: (i) unamortized original issue discount or premium; (ii) unamortized acquisition date fair value adjustments for AGM and AGMH debt; and (iii) debt issuance costs. Original issue discount and premium, acquisition date fair value adjustments for AGM and AGMH debt, and debt issuance costs are accreted into interest expense over the contractual term of the applicable debt. When long-term debt is redeemed, the difference between the cash paid to redeem the debt and the carrying value of the debt is reported as a “loss on extinguishment of debt” in the consolidated statements of operations. CCS are carried at fair value with changes in fair value reported in the consolidated statement of operations. See Note 9, Fair Value Measurement, – Other Assets – Committed Capital Securities, for a discussion of the fair value measurement of the CCS.
Employee Benefit Plans | Share-based compensation expense is based on the grant date fair value using the grant date closing price or the Monte Carlo or Black-Scholes-Merton (Black-Scholes) pricing models. Except for the share-based awards to retirement-eligible employees, 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. For retirement-eligible employees, the Company expenses the portion of the unvested time-based awards that fully vest upon retirement eligibility. The fair value of each award under the Assured Guaranty Ltd. Employee Stock Purchase Plan is estimated at the beginning of the offering period using the Black-Scholes option valuation model and are expensed over the period which the employee participates in the plan and pays for the shares.
Income Taxes | 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.
Leases | The Company determines if an arrangement is a lease at inception. For operating leases with an original term of more than 12 months, where the Company is the lessee, it recognizes a right-of-use (ROU) asset in “other assets” and a lease liability in “other liabilities” on the consolidated balance sheets. An ROU asset represents the Company’s right to use an underlying asset for the lease term, and a lease liability represents the Company’s obligation to make lease payments arising from the lease. At the inception of a lease, the total fixed payments under a lease agreement are discounted utilizing an incremental borrowing rate that represents the Company’s collateralized borrowing rate. The rate is determined based on the lease term as of the lease commencement date. Some of the Company’s leases include renewal options, which are not included in the lease terms unless the Company is reasonably certain it will exercise the option. The Company elected the practical expedient to account for all lease components and their associated non-lease components (i.e., common area maintenance, real estate taxes, building insurance, etc.) as a single lease component and include all fixed payments in the measurement of ROU assets and lease liabilities. Operating lease expense is recognized on a straight-line basis over the lease term. Costs related to variable lease and non-lease components for the Company’s leases are expensed in the period incurred. Sublease income is earned on a straight-line basis over the term of the lease. The Company assesses ROU assets for impairment when certain events occur or when there are changes in circumstances including potential alternative uses. If circumstances require an ROU asset to be tested for possible impairment, and the carrying value of the ROU asset is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Any impairment is reported in “other operating expenses” in the consolidated statement of operations.
Commitments and Contingencies | 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. Additionally, it discloses such amounts if material to the financial position of the Company. 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 would be disclosed below. The Company reviews relevant information with respect to its litigation and regulatory matters on a quarterly basis and updates its accruals, disclosures, and estimates of reasonably possible loss based on such reviews.
Stockholders' Equity | The Company records share repurchases as a reduction to “common shares” and “additional paid-in capital.” Once additional paid-in capital has been exhausted, share repurchases are recorded as a reduction to common shares and retained earnings.
Earnings Per Share | The Company computes earnings per share (EPS) using the two-class method, which is an earnings allocation formula that determines EPS for: (i) each class of common shares (the Company has a single class of common shares); and (ii) participating securities according to dividends declared (or accumulated) and participation rights in undistributed earnings. Awards and share units under the AGS SERP with non-forfeitable dividends are considered participating securities. Basic EPS is computed by dividing net income (loss) 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), 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.
Related Party Transactions | The Company follows ASC 850, “Related Party Transactions”, for the identification and disclosure of related party transactions. Pursuant to ASC 850, related parties include: (i) the Company’s affiliates; (ii) entities for which investments in their equity securities would be required, absent the election of the FVO to be accounted for by the equity method; (iii) trusts for the benefit of employees, such as pension and profit sharing trusts that are managed by or under the trusteeship of management; (iv) the Company’s principal owners; (v) the Company’s management; (vi) other parties with which the Company may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests; and (vii) other parties that can significantly influence the management or operating policies of the transacting parties or that have an ownership interest in one of the transacting parties and can significantly influence the other to an extent that one or more of the transacting parties might be prevented from fully pursuing its own separate interests. Related party amounts and transactions disclosed in this note include transactions with “Related Persons” as defined in Item 404 of SEC’s Regulation S-K as well as “related parties” as defined in ASC 850.
