Organization, Consolidation and Presentation of Financial Statements [Abstract]

The unaudited interim condensed 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 and 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. These unaudited interim condensed consolidated financial statements are as of September 30, 2019 and cover the three-month period ended September 30, 2019 (Third Quarter 2019), the three-month period ended September 30, 2018 (Third Quarter 2018), the nine-month period ended September 30, 2019 (Nine Months 2019) and the nine-month period ended September 30, 2018 (Nine Months 2018). Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but is not required for interim reporting purposes, has been condensed or omitted. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The presentation of cash flow amounts related to short-term investments was changed during the fourth quarter of 2018 to reflect cash flows on a gross, rather than a net, basis. The presentation of equity in net earnings of investees was changed in 2019 to reclassify amounts previously reported in net investment income and other income to a separate line item on the condensed consolidated statements of operations. Certain prior year balances have been reclassified to conform to the current year's presentation.

Consolidation

The unaudited interim condensed consolidated financial statements include the accounts of AGL, its direct and indirect subsidiaries and its consolidated VIEs. Intercompany accounts and transactions between and among all consolidated entities have been eliminated.

New Accounting Pronouncements Adopted and Future Application

Adopted Accounting Standards

Leases

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842). The Company adopted Topic 842 on January 1, 2019 using the optional transition method that allows the Company to initially apply the new requirements at the effective date, with no revision to prior periods. See Note 12, Commitments and Contingencies, for additional information.

Premium Amortization on Purchased Callable Debt Securities

In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Topic 310-20) - Premium Amortization on Purchased Callable Debt Securities. This ASU shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date. This ASU was adopted on January 1, 2019, with no effect on the Company's condensed consolidated financial statements.

Future Application of Accounting Standards

Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU provides a new current expected credit loss model to account for credit losses on certain financial assets (e.g., reinsurance recoverables, premium receivables, and held-to-maturity debt securities) and off-balance sheet exposures (e.g., loan commitments). That model requires an entity to estimate lifetime credit losses related to certain financial assets, based on relevant historical information, adjusted for current conditions and reasonable and supportable forecasts that could affect the collectability of the reported amount. The ASU also makes targeted amendments to the current impairment model for available-for-sale debt securities, which includes requiring the recognition of an allowance rather than a direct write-down of the investment. The allowance may be reversed in the event that the credit of an issuer improves. In addition, the ASU eliminates the existing guidance for purchased credit impaired assets and introduces a new model for purchased financial assets with credit deterioration, such as the Company's loss mitigation securities, which requires the

recognition of an initial allowance for credit losses. Under the new guidance, the amortized cost would be the purchase price plus the allowance at the acquisition date.

The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. For reinsurance recoverables, premiums receivable and debt instruments such as loans and held to maturity securities, entities will be required to record a cumulative-effect adjustment to the statement of financial position as of the beginning of the first reporting period in which the guidance is adopted. The changes to the impairment model for available-for-sale securities and purchased financial assets with credit deterioration are to be applied prospectively. Early adoption of the amendments is permitted; however, the Company does not plan to adopt this ASU until January 1, 2020. The Company does not expect ASU 2016-13 to have a material effect on shareholders' equity at the date of adoption.

Targeted Improvements to the Accounting for Long-Duration Contracts

In August 2018, the FASB issued ASU 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts. The amendments in this ASU:


•	improve the timeliness of recognizing changes in the liability for future policy benefits and modify the rate used to discount future cash flows,


•	simplify and improve the accounting for certain market-based options or guarantees associated with deposit (or account balance) contracts,


•	simplify the amortization of deferred acquisition costs, and


•	improve the effectiveness of the required disclosures.

This ASU does not affect the Company’s financial guaranty insurance contracts, but may affect its accounting for certain non-financial guaranty contracts. In October 2019, the FASB affirmed its decision to defer the effective date of the ASU to January 1, 2022. The Company does not plan to adopt this ASU early, and does not expect this ASU to have a material effect on its condensed consolidated financial statements.

Fair Value of Financial Instruments

The Company carries a portion of its assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., exit price). The price represents the price available in the principal market for the asset or liability. If there is no principal market, then the price is based on a hypothetical market that maximizes the value received for an asset or minimizes the amount paid for a liability (i.e., the most advantageous market).

Fair value is based on quoted market prices, where available. If listed prices or quotes are not available, fair value is based on either internally developed models that primarily use, as inputs, market-based or independently sourced market parameters, including but not limited to yield curves, interest rates and debt prices or with the assistance of an independent third party using a discounted cash flow approach and the third party’s proprietary pricing models. In addition to market

information, models also incorporate transaction details, such as maturity of the instrument and contractual features designed to reduce the Company’s credit exposure, such as collateral rights as applicable.

Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments include amounts to reflect counterparty credit quality, the Company’s creditworthiness and constraints on liquidity. As markets and products develop and the pricing for certain products becomes more or less transparent, the Company may refine its methodologies and assumptions. During Nine Months 2019, no changes were made to the Company’s valuation models that had, or are expected to have, a material impact on the Company’s condensed consolidated balance sheets or statements of operations and comprehensive income.

The Company’s methods for calculating fair value produce a fair value that may not be indicative of net realizable value or reflective of future fair values. The use of different methodologies or assumptions to determine fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

The categorization within the fair value hierarchy is determined based on whether the inputs to valuation techniques used to measure fair value are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Company estimates of market assumptions. The fair value hierarchy prioritizes model inputs into three broad levels as follows, with Level 1 being the highest and Level 3 the lowest. An asset's or liability’s categorization is based on the lowest level of significant input to its valuation.

Level 1—Quoted prices for identical instruments in active markets. The Company generally defines an active market as a market in which trading occurs at significant volumes. Active markets generally are more liquid and have a lower bid-ask spread than an inactive market.

Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and observable inputs other than quoted prices, such as interest rates or yield curves and other inputs derived from or corroborated by observable market inputs.

Level 3—Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable. Level 3 financial instruments also include those for which the determination of fair value requires significant management judgment or estimation.
