Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Business and Significant Accounting Policies | Business and Significant Accounting Policies The accompanying Condensed Consolidated Financial Statements of Argo Group International Holdings, Ltd. and its subsidiaries (“Argo Group,” “we,” “us,” “our” or the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Argo Group is an underwriter of specialty insurance products in the property and casualty market. The preparation of interim 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 at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. The major estimates reflected in our Condensed Consolidated Financial Statements include, but are not limited to, reserves for losses and loss adjustment expenses; reinsurance recoverables, including the reinsurance recoverables allowance for expected credit losses; fair value of investments and assessment of potential impairment, including the allowance for credit losses on fixed maturity securities; valuation of goodwill and our deferred tax asset valuation allowance. Actual results could materially differ from those estimates. Certain financial information that is normally included in annual Condensed Consolidated Financial Statements, including certain financial statement footnotes, prepared in accordance with GAAP, is not required for interim reporting purposes and has been condensed or omitted. These statements should be read in conjunction with the Condensed Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission ("SEC") (the “2022 Form 10-K”). The interim financial information as of, and for the three and nine months ended, September 30, 2023 and 2022 is unaudited. However, in the opinion of management, the interim information includes all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the results presented for the interim periods. The operating results for the interim periods are not necessarily indicative of the results to be expected for the full year. All significant intercompany amounts have been eliminated in consolidation. Certain reclassifications have been made to financial information presented for prior years to conform to the current year’s presentation. Loss Portfolio Transfer - U.S. On November 9, 2022, the U.S. loss portfolio transaction with a wholly owned subsidiary Enstar Group Limited covering a majority of the Company’s U.S. casualty insurance reserves, including construction, for accident years 2011 to 2019 closed. The financial statement impact of this transaction on the closing date, which was recorded in the fourth quarter of 2022, consisted mainly of ceded premiums for a total of $121.0 million and was reflected in Earned premiums in our Condensed Consolidated Statements of Income (Loss). In 2023, the reserves ceded under the U.S. loss portfolio transfer exceeded the consideration paid by $35.1 million, and is reflected as a deferred gain liability included in Accrued underwriting expenses and other liabilities on the Condensed Consolidated Balance Sheets, net of amortization. The deferred gain is amortized to earnings using the recovery method over the estimated claims settlement period. Any potential future loss development on the U.S. loss portfolio transfer increases the deferred gain if unfavorable, or decreases the deferred gain if favorable, and a cumulative amortization adjustment based on the change in estimate is recorded to earnings. Sale of Argo Underwriting Agency Limited On September 8, 2022, Argo International Holdings Limited (the “Seller”), a wholly-owned subsidiary of the Company, and Ohio Farmers Insurance Company (the “Buyer”), part of the Westfield group of insurance companies, entered into a sale and purchase agreement (the “Transaction”) under which the Seller agreed to sell, and the Buyer agreed to purchase, the entire issued share capital of Argo Underwriting Agency Limited (“AUA”), for which the financial results are reported in our International segment. This transaction simplifies our reporting structure and is intended to drive greater efficiencies. The base cash consideration for the purchase was $125.0 million, which was adjusted to reflect the extent by which AUA’s net assets at completion are greater or lesser than AUA net assets as of March 31, 2022. In the third quarter of 2022, as a result of the sale, an impairment was recorded in the amount of $28.5 million, consisting of $17.3 million of indefinite lived intangible assets and $11.2 million of goodwill, representing the difference between the carrying value and implied fair value as determined by the consideration to be received. In addition, the Buyer was obliged to replace certain funds provided by the Company to support the activities of AUA and certain of its subsidiaries at Lloyd’s of London, which would then be released to the Company. As of December 31, 2022, the Company reported the assets and liabilities of this block of business as held-for-sale on Condensed Consolidated Balance Sheets with results continuing to be reported within the Condensed Consolidated Statements of Income (Loss) and the International Operations segment. The Company determined that the Transaction did not represent a strategic shift, and therefore, did not meet the requirements for discontinued operations. On February 2, 2023, the Seller completed the sale of the entire issued share capital of AUA. At the closing, the Company received total consideration of $155.7 million, which included cash proceeds of $125.1 million as base consideration and an additional $30.6 million which was placed in escrow by the Buyer related to certain reinsurance-related recoverables. The funds in escrow may be released to the Seller over a period of two years following the closing. At the end of the two-year escrow period, any remaining balance of the escrow will be returned to the Buyer. As a result of the sale, we realized a loss of $20.3 million in the first quarter of 2023, which is included as a component of Net realized investment and other gains (losses) in our Condensed Consolidated Statements of Income (Loss). This loss is due to the realization of unrealized investment losses, which was previously a component of accumulated other comprehensive income. Through the third quarter of 2023, $7.8 million of the consideration placed in escrow was released to the Company. In addition, the total consideration was adjusted to $161.3 million based on a mutually agreed final closing balance sheet, which resulted in an additional $5.6 million of cash proceeds received by the Company in July 2023. Sale of ArgoGlobal SE On June 22, 2022, we completed the sale of our Malta operations, ArgoGlobal Holdings (Malta) Ltd. and subsidiaries (“AGSE”) to RiverStone Holdings Limited (part of the RiverStone International Group) for €4.9 million (approximately $5.2 million), subject to the terms and conditions set forth in the purchase agreement. AGSE is one of the business units within our International Operations reporting segment. As a result, we realized a loss on the sale of AGSE of $21.3 million, which is included as a component of Net realized investment and other gains (losses) in our Condensed Consolidated Statements of Income (Loss). This amount includes $4.5 million of losses from the realization of historical foreign currency translation, which was previously a component of accumulated other comprehensive income. Loss Portfolio Transfer In April 2022, Argo Managing Agency Limited, for and on behalf of Lloyd’s Syndicate 1200, reached an agreement to enter into a loss portfolio transfer of the 2018 and 2019 years of account to Riverstone Managing Agency Limited, for and on behalf of Lloyd's Syndicate 3500, retrospectively from January 1, 2022. Sale of Argo Seguros Brasil S.A. On February 15, 2022, we completed the sale of our Brazilian operations, Argo Seguros Brasil S.A. (“Argo Seguros”), to Spice Private Equity Ltd., an investment company focused on global private equity investments, for a purchase price of 160 million Brazilian Reais (approximately $30.5 million), subject to the terms and conditions set forth in the purchase agreement. Argo Seguros was one of the units within our International Operations reporting segment. As a result, we realized a loss on the sale of Argo Seguros of $28.5 million, which is included as a component of Net realized investment and other gains (losses) in our Condensed Consolidated Statements of Income (Loss). This loss was primarily attributable to the realization of historical foreign currency translation, which was previously a component of accumulated other comprehensive income. We previously recognized a $6.3 million loss during 2021 as we adjusted the carrying value of Argo Seguros to its fair value. In third quarter of 2022, a final purchase price was established in the amount of 140 million Brazilian Reais (approximately $26.9 million). As a result, we realized a loss on the sale of Argo Seguros of $33.8 million in 2022, which is included as a component of Net realized investment and other gains (losses) in our Condensed Consolidated Statements of Income (Loss). |

The unrealized losses as of September 30, 2023 are primarily driven from interest rate movements. Allowance for Credit Losses For fixed maturities with a decline in fair value below the 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 investment and other gains (losses) in the Condensed Consolidated Statements of Income (Loss). The allowance is limited to the difference between amortized cost and fair value. The estimated recoverable value is the present value of cash flows expected to be collected, as determined by management. The difference between fair value and amortized cost that is not associated with credit-related factors is recognized in the Condensed Consolidated Statements of Comprehensive Income (Loss). Accrued interest is excluded from the measurement of the allowance for credit losses. When determining if a credit loss has been incurred, we may consider the historical performance of the security, available market information and security specific considerations such as the priority payment of the security. In addition, inputs used in our analysis include, but are not limited to, credit ratings and downgrades, delinquency rates, missed scheduled interest or principal payments, purchase yields, underlying asset performance, collateral types, modeled default rates, modeled severity rates, call/prepayment rates, expected cash flows, industry concentrations, and potential or filed bankruptcies or restructurings. In cooperation with our investment managers, we evaluate for credit losses each quarter utilizing a bottom up review approach. At the security level, a determination is made as to whether a decline in fair value below the amortized cost basis is due to credit-related or noncredit-related factors. If we determine that all or a portion of a fixed maturity is uncollectible, the uncollectible amortized cost is written off with a corresponding reduction to the allowance for credit losses. If we collect cash flows that were previously written off, the recovery is recognized in Net investment and other gains (losses) . We also consider whether we intend to sell an available-for-sale security or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost. In these instances, a decline in fair value is recognized in Net investment and other gains (losses) in the Condensed Consolidated Statements of Income (Loss) based on the fair value of the security at the time of assessment, resulting in a new cost basis for the security. The following table presents a roll-forward of the changes in allowance for credit losses on available-for-sale fixed maturities by industry category for the three and nine months ending September 30, 2023 and 2022, respectively: (in millions) Foreign Governments Obligations of states and political subdivisions Corporate bonds Asset backed securities Total Beginning balance, June 30, 2023 $ 1.0 $ — $ 1.4 $ 0.1 $ 2.5 Securities for which allowance was not previously recorded — 0.5 1.4 — 1.9 Securities sold during the period — — (0.1) — (0.1) Reductions for credit impairments — — — — — Additional net increases (decreases) in existing allowance 0.1 — — — 0.1 Ending balance, September 30, 2023 $ 1.1 $ 0.5 $ 2.7 $ 0.1 $ 4.4 (in millions) Foreign Governments Obligations of states and political subdivisions Corporate bonds Asset backed securities Total Beginning balance, June 30, 2022 $ 0.5 $ 0.4 $ 1.0 $ 0.1 $ 2.0 Securities for which allowance was not previously recorded 0.1 — 1.1 — 1.2 Securities sold during the period — — — — — Reductions for credit impairments — — — — — Additional net increases (decreases) in existing allowance 0.1 — — — 0.1 Ending balance, September 30, 2022 $ 0.7 $ 0.4 $ 2.1 $ 0.1 $ 3.3 (in millions) Foreign Governments Obligations of states and political subdivisions Corporate bonds Asset backed securities Total Beginning balance, January 1, 2023 $ 0.7 $ 0.4 $ 1.6 $ 0.1 $ 2.8 Securities for which allowance was not previously recorded 0.1 0.5 2.1 — 2.7 Securities sold during the period — — (0.5) — (0.5) Reductions for credit impairments — — — — — Additional net increases (decreases) in existing allowance 0.3 (0.4) (0.5) — (0.6) Ending balance, September 30, 2023 $ 1.1 $ 0.5 $ 2.7 $ 0.1 $ 4.4 (in millions) Foreign Governments Obligations of states and political subdivisions Corporate bonds Asset backed securities Total Beginning balance, January 1, 2022 $ 0.2 $ — $ 2.2 $ 0.1 $ 2.5 Securities for which allowance was not previously recorded 0.4 — 1.6 — 2.0 Securities sold during the period (0.1) — (0.6) — (0.7) Reductions for credit impairments — — (1.4) — (1.4) Additional net increases (decreases) in existing allowance 0.2 0.4 0.3 — 0.9 Ending balance, September 30, 2022 $ 0.7 $ 0.4 $ 2.1 $ 0.1 $ 3.3 The change in allowance for credit losses on fixed maturity securities, included in Net investment and other gains (losses) in the Condensed Consolidated Statements of Income (Loss) was $2.0 million and $2.1 million for the three and nine months ended September 30, 2023, respectively. The change in allowance for credit losses on fixed maturity securities, included in Net investment and other gains (losses) in the Condensed Consolidated Statements of Income (Loss) was $1.3 million and $2.9 million for the three and nine months ended September 30, 2022. For commercial mortgage loans an allowance for credit losses is established at the time of origination or purchase, as necessary, and is updated each reporting period. Changes in the allowance for credit losses are recorded in Net investment and other gains (losses) . This allowance reflects the risk of loss, even when that risk is remote, that is expected over the remaining contractual life of the loan. The allowance for credit losses considers available relevant information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts of future economic conditions. Commercial Mortgage Loans Commercial mortgage loan investments are composed of participation interests in a portfolio of commercial mortgage loans. Loan collateral is diversified with regard to property type and geography.

We maintain assets pledged as collateral in support of irrevocable letters of credit issued under the terms of certain reinsurance agreements for reported loss and loss expense reserves. The following table presents our components of restricted assets: (in millions) September 30, 2023 December 31, 2022 Securities on deposit for regulatory and other purposes $ 141.2 $ 149.3 Securities pledged as collateral for letters of credit and other 104.5 169.8 Securities on deposit supporting Lloyd’s business (1) — 171.4 Total restricted investments $ 245.7 $ 490.5 (1) During the second quarter 2023, the funds at Lloyd’s (FAL) previously used to support the activities of AUA and its subsidiaries, were released to the Company. Fair Value Measurements Fair value is the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability, or in the absence of a principal market, the most advantageous market. Market participants are buyers and sellers in the principal (or most advantageous) market that are independent, knowledgeable, able to transact for the asset or liability and willing to transfer the asset or liability. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value. The inputs of these valuation techniques are categorized into three levels. • Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that can be accessed at the reporting date. We define actively traded as a security that has traded in the past seven days. • Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. We receive one quote per instrument for Level 2 inputs. • Level 3 inputs are unobservable inputs. Unobservable inputs reflect our own judgments about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. To validate the fair value of investments in the Company’s Condensed Consolidated Financial Statements, we receive prices from multiple sources including third-party pricing services and our outside investment managers. Through a comparative analysis, the Company validates the reasonableness of its valuations. These prices are determined using observable market information such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things. We have reviewed the processes used by the third-party providers for pricing the securities and have determined that these processes result in fair values consistent with GAAP requirements. In addition, we review these prices for reasonableness, and have not adjusted any prices received from the third-party providers as of September 30, 2023 and December 31, 2022. A description of the valuation techniques we use to measure assets at fair value is as follows: Fixed Maturities (Available-for-Sale) Levels 1 and 2: • United States Treasury securities are typically valued using Level 1 inputs. For these securities, we obtain fair value measurements from third-party pricing services using quoted prices (unadjusted) in active markets at the reporting date. • United States Government agencies, non-U.S. Government securities, obligations of states and political subdivisions, credit securities and foreign denominated government and credit securities are reported at fair value using Level 2 inputs. For these securities, we obtain fair value measurements from third-party pricing services. Observable data may include dealer quotes, market spreads, yield curves, live trading levels, trade execution data, credit information and the security’s terms and conditions, among other things. • Asset and mortgage-backed securities and collateralized loan obligations are reported at fair value using Level 2 inputs. For these securities, we obtain fair value measurements from third-party pricing services. Observable data may include dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things. Fixed Maturities (Available-for-Sale) Levels 3: We own term loans and asset-back securities that are valued using unobservable inputs. Equity Securities Level 1: Equity securities are principally reported at fair value using Level 1 inputs. For these securities, we obtain fair value measurements from a third-party pricing service using quoted prices (unadjusted) in active markets at the reporting date. Equity Securities Level 3: We own certain equity securities that are reported at fair value using Level 3 inputs. The valuation techniques for these securities include the following: • Fair value measurements for an investment in an equity fund obtained by applying final prices provided by the administrator of the fund, which is based upon certain estimates and assumptions. • Fair value measurements from brokers and independent valuation services, both based upon estimates, assumptions and other unobservable inputs. Other Investments Level 2: Foreign regulatory deposits are assets held in trust in jurisdictions where there is a legal and regulatory requirement to maintain funds locally in order to protect policyholders. Lloyd’s is the appointed investment manager for the funds. These assets are invested in short-term government securities, agency securities and corporate bonds and are valued using Level 2 inputs based upon values obtained from Lloyd’s. Short-term Investments: Short-term investments are principally reported at fair value using Level 1 inputs, with the exception of short-term corporate and governmental bonds reported at fair value using Level 2 inputs as described in the fixed maturities section above. Values for the investments categorized as Level 1 are obtained from various financial institutions as of the reporting date. Based on an analysis of the inputs, our financial assets and liabilities measured at fair value on a recurring basis have been categorized as follows: Fair Value Measurements at Reporting Date Using (in millions) September 30, Level 1 (1) Level 2 (2) Level 3 (3) Fixed maturities U.S. Governments $ 364.5 $ 362.4 $ 2.1 $ — Foreign Governments 27.9 — 27.9 — Obligations of states and political subdivisions 94.8 — 94.8 — Corporate bonds 1,177.7 — 1,155.6 22.1 Commercial mortgage-backed securities 271.4 — 271.4 — Residential mortgage-backed securities 239.7 — 239.7 — Asset-backed securities 130.3 — 112.6 17.7 Collateralized loan obligations 231.1 — 231.1 — Total fixed maturities 2,537.4 362.4 2,135.2 39.8 Equity securities 11.6 4.4 — 7.2 Other investments 0.9 — 0.9 — Short-term investments 1,222.7 1,222.5 0.2 — Derivatives 1.2 — 1.2 — Total assets $ 3,773.8 $ 1,589.3 $ 2,137.5 $ 47.0 (1) Quoted prices in active markets for identical assets (2) Significant other observable inputs (3) Significant unobservable inputs Fair Value Measurements at Reporting Date Using (in millions) December 31, Level 1 (1) Level 2 (2) Level 3 (3) Fixed maturities U.S. Governments $ 380.7 $ 378.7 $ 2.0 $ — Foreign Governments 28.4 — 28.4 — Obligations of states and political subdivisions 99.8 — 99.8 — Corporate bonds 1,234.1 — 1,212.1 22.0 Commercial mortgage-backed securities 285.4 — 285.4 — Residential mortgage-backed securities 270.0 — 270.0 — Asset-backed securities 139.2 — 120.5 18.7 Collateralized loan obligations 237.9 — 237.9 — Total fixed maturities 2,675.5 378.7 2,256.1 40.7 Equity securities 43.9 28.4 — 15.5 Other investments 0.3 — 0.3 — Short-term investments 449.6 449.3 0.3 — Derivatives 5.2 — 5.2 — Total assets $ 3,174.5 $ 856.4 $ 2,261.9 $ 56.2 (1) Quoted prices in active markets for identical assets (2) Significant other observable inputs (3) Significant unobservable inputs The fair value measurements in the tables above do not equal Total investments on our Condensed Consolidated Balance Sheets as they primarily exclude other investments that are accounted for under the equity-method of accounting as well as hedge funds which are carried at NAV as a practical expedient.

Refer to the sale of AUA in Note 1, “Business and Significant Accounting Policies” for additional information. For the nine months ended September 30, 2022, refer to the sale of Argo Seguros and AGSE in Note 1, “Business and Significant Accounting Policies” for additional information. (2) In connection with the sale of AUA, the Company entered into two retroactive reinsurance agreements with AUA subsidiaries. (3) Loss portfolio transfer on Syndicate 1200's reserves for the 2018 and 2019 years of account. Refer to Note 1, “Business and Significant Accounting Policies” for additional information. (4) Amount represents the change in reserves due to changing our participation in Syndicates 1200 and 1910. For the nine months ended September 30, 2023, the balance has been reduced to zero as a result of the sale of AUA. Reserves for losses and LAE represent the estimated indemnity cost and related adjustment expenses necessary to investigate and settle claims. Such estimates are based upon individual case estimates for reported claims, estimates from ceding companies for reinsurance assumed and actuarial estimates for losses that have been incurred but not yet reported to the insurer. Any change in probable ultimate liabilities is reflected in current operating results. The impact from the (favorable) unfavorable development of prior accident years’ loss and LAE reserves on each reporting segment is presented below: For the Nine Months Ended (in millions) 2023 2022 U.S. Operations $ 111.7 $ 27.9 International Operations 11.7 0.8 Run-off Lines 2.6 2.9 Total (favorable) unfavorable prior-year development $ 126.0 $ 31.6 The following describes the primary factors behind each segment’s net prior accident year reserve development for the nine months ended September 30, 2023 and 2022: Nine months ended September 30, 2023: • U.S. Operations: Net unfavorable development primarily related to liability and professional lines partially offset by favorable development in specialty lines. The liability lines development was driven by actual losses greater than expected including the impact of large claims with a significant portion of the unfavorable development coming from businesses we have exited. The professional lines development was driven by movements on individual management liability claims. The favorable development in specialty lines was due to a lack of claim activity in surety business. • International Operations : Net unfavorable development primarily related to movements on claims in professional and liability lines in our Bermuda operations partially offset by favorable development in runoff Reinsurance lines. • Run-off Lines: Net unfavorable loss reserve development on prior accident years in other run-off lines. Nine months ended September 30, 2022: • U.S. Operations : Unfavorable development primarily related to liability and property lines, including the impact of large losses, partially offset by favorable development in specialty lines. The unfavorable prior year development was largely driven by businesses we have exited, and relates to accident years 2019 and prior partially offset by favorable prior year development on accident years 2020 and 2021. • International Operations : Unfavorable development primarily related to unfavorable movements in professional lines in Argo Insurance Bermuda, partially offset by favorable development in Syndicate 1200 property and liability lines. • Run-off Lines: Unfavorable loss reserve development on prior accident years in other run-off lines. Our reserves represent the best estimate of our ultimate liabilities, based on currently known facts, current law, current technology and reasonable assumptions where facts are not known. Due to the significant uncertainties and related management judgments, there can be no assurance that future favorable or unfavorable loss development, which may be material, will not occur. |

Investment securities, commercial mortgage loan investments, and short-term investments. See Note 3, “Investments,” for additional information. Premiums receivable and reinsurance recoverables on paid losses. The carrying value of current receivables and reinsurance recoverables on paid losses approximates fair value due to short term nature. Debt. At September 30, 2023 and December 31, 2022, the fair value of our debt instruments is determined using both Level 1 and Level 2 inputs, as previously defined in Note 3, “Investments.” We receive fair value prices for similar financial instruments being traded in active markets. These prices are determined using observable market information such as publicly traded quoted prices, and trading prices for similar financial instruments actively being traded in the current market. We have reviewed the processes used by the third-party providers for pricing the instruments and have determined that these processes result in fair values consistent with GAAP requirements. In addition, we review these prices for reasonableness, and have not adjusted any prices received from the third-party providers as of September 30, 2023 and December 31, 2022. A description of the valuation techniques we use to measure these liabilities at fair value is as follows: Senior Unsecured Fixed Rate Notes Level 1: • Our senior unsecured fixed rate notes are valued using Level 1 inputs. For these securities, we obtain fair value measurements from a third-party pricing service using quoted prices (unadjusted) in active markets at the reporting date. Junior Subordinated Debentures and Floating Rate Loan Stock Level 2: • Our trust preferred debentures, subordinated debentures and floating rate loan stock are typically valued using Level 2 inputs. For these securities, we obtain fair value measurements using quoted prices for similar securities being traded in active markets at the reporting date, as our specific debt instruments are less frequently traded. A summary of our financial instruments whose carrying value did not equal fair value is shown below: September 30, 2023 December 31, 2022 (in millions) Carrying Fair Carrying Fair Junior subordinated debentures: Trust preferred debentures $ 172.6 $ 160.6 $ 172.7 $ 165.8 Subordinated debentures 86.2 80.4 85.9 88.1 Total junior subordinated debentures 258.8 241.0 258.6 253.9 Senior unsecured fixed rate notes 140.6 126.7 140.5 112.7 Floating rate loan stock (1) — — 54.7 52.5 $ 399.4 $ 367.7 $ 453.8 $ 419.1 (1) At December 31, 2022, floating rate loan stock reclassified to liabilities held-for-sale.

Share-Based Payment Arrangement [Abstract] | |
Share-based Compensation | Share-based Compensation Argo Group’s 2019 Omnibus Incentive Plan In May 2019, our shareholders approved the 2019 Omnibus Incentive Plan (the “2019 Plan”), which provides equity-based and cash-based incentives to key employees and non-employee directors. The intent of the 2019 Plan is to encourage and provide for the acquisition of an ownership interest in Argo Group, enabling us to attract and retain qualified and competent persons to serve as members of our management team and Board of Directors. The 2019 Plan authorizes 1,885,000 common shares to be granted as equity-based awards. No further grants will be made under any prior plan; however, any awards under a prior plan that are outstanding as of the effective date shall remain subject to the terms and conditions of, and be governed by, such prior plan. Awards granted under the 2019 Plan may be in the form of stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards, other stock-based awards or other cash-based awards. Awards may be granted either alone, in addition to or in tandem with other awards authorized under the 2019 Plan. Awards that are settled in stock will count as one share for the purposes of reducing the share reserve under the 2019 Plan. Shares issued under this plan may be shares that are authorized and unissued or shares that we have reacquired, including shares purchased on the open market. Stock options and stock appreciation rights are required to have an exercise price that is not less than the fair market value on the date of grant. The term of these awards is not to exceed ten years. Restricted Shares A summary of non-vested restricted share activity as of September 30, 2023 and changes during the nine months then ended is as follows: Shares Weighted-Average Outstanding at January 1, 2023 341,670 $ 42.19 Granted — — Vested and issued (114,101) 41.66 Expired or forfeited (86,944) 43.77 Outstanding at September 30, 2023 140,625 $ 41.65 The restricted shares generally vest over one Underwriting, acquisition and insurance expenses in the accompanying Condensed Consolidated Statements of Income (Loss). As of September 30, 2023, there was $4.4 million of total unrecognized compensation, excluding any potential forfeitures, cost related to restricted share compensation arrangements granted by Argo Group. Performance Shares We have issued to certain employees non-vested restricted stock awards whose vesting is subject to the achievement of certain performance measures. The non-vested performance share awards vest over three A summary of non-vested performance share activity as of September 30, 2023 and changes during the nine months then ended is as follows: Shares Weighted-Average Outstanding at January 1, 2023 124,974 $ 46.41 Granted — — Vested and issued — — Expired or forfeited (56,762) 45.01 Outstanding at September 30, 2023 68,212 $ 47.57 Net expense for the three months ended September 30, 2023 was nil. Net expense recouped for the performance shares under this plan was $2.4 million for the nine months ended September 30, 2023. Expense recognized under this plan for the performance shares was $0.5 million for the three months ended September 30, 2022. For the nine months ended September 30, 2022, we recouped expense of $0.1 million. The recoupment of expense in 2023, producing a net benefit to the Condensed Consolidated Statements of Income (Loss), was primarily due to the reduction of the expense for the Company not achieving the required performance measures and the adjustment of the expected forfeitures on the remaining awards. The recoupment of expenses recognized in 2022 was primarily attributable to the forfeiture of awards due to the departure of our former president and chief executive officer. As of September 30, 2023, total unrecognized compensation cost was nil, adjusted for anticipated forfeitures due to not meeting the specified performance measures by Argo Group.

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes We are incorporated under the laws of Bermuda and, under current Bermuda law, are not obligated to pay any taxes in Bermuda based upon income or capital gains. We have received an undertaking from the Supervisor of Insurance in Bermuda pursuant to the provisions of the Exempted Undertakings Tax Protection Amendment Act, 2011, which exempts us from any Bermuda taxes computed on profits, income or any capital asset, gain or appreciation or any tax in the nature of estate, duty or inheritance tax, at least until the year 2035. Argo Group International Holdings, Ltd. does not consider itself to be engaged in a trade or business in the U.S. or the U.K. and, accordingly, does not expect to be subject to direct U.S. or U.K. income taxation. We have a subsidiary based in the U.K. that is subject to the tax laws of that country. Under current law, the subsidiary is taxed at the applicable corporate tax rates. On February 2, 2023, Argo completed the sale of the entire issued share capital of AUA. Refer to the sale of AUA in Note 1, “Business and Significant Accounting Policies” for additional information. Certain of the U.K. subsidiaries included in the AUA sale were deemed to be engaged in business in the U.S., and therefore, subject to U.S. corporate tax in respect of a proportion of their U.S. underwriting business only. Relief was available against the U.K. tax liabilities in respect of overseas taxes paid that arose from the underwriting business. Our U.K. subsidiaries file separate U.K. income tax returns. We have subsidiaries based in the U.S. that are subject to U.S. tax laws. Under current law, these subsidiaries are taxed at the applicable corporate tax rates. Our U.S. subsidiaries file a consolidated U.S. federal income tax return. We also have operations in Ireland and Italy which also are subject to income taxes imposed by the jurisdiction in which they operate. Additionally, we have operations in Barbados which is not subject to income tax under the laws of that country. On August 16, 2022, U.S. legislation referred to as the Inflation Reduction Act of 2022 was enacted. This legislation enacted a new Corporate Alternative Minimum Tax and Excise Tax on Repurchases of Corporate Stock. The Company does not anticipate an impact to our financial statements in regard to the recent legislative change. Our expected income tax provision computed on pre-tax income (loss) at the weighted average tax rate has been calculated as the sum of the pre-tax income (loss) in each jurisdiction multiplied by that jurisdiction’s applicable statutory tax rate. For the three and nine months ended September 30, 2023 and 2022, pre-tax income (loss) attributable to our operations and the corresponding operations’ effective tax rates were as follows: For the Three Months Ended September 30, 2023 2022 (in millions) Pre-Tax Effective Pre-Tax Effective Bermuda (9.8) — % $ (11.3) — % United States (18.1) (95.5) % (3.2) 46.3 % United Kingdom (1.6) (22.5) % (37.6) 6.8 % Barbados — (1) — % — — % United Arab Emirates — — % 0.5 — % Ireland — (1) — % (1.3) — % Italy 0.2 20.0 % 0.1 (1.7) % Malta — — % — — % Pre-tax income (loss) (29.3) (60.1) % (52.8) 7.6 % (1) Pre-tax income (loss) for the respective year was less than $0.1 million. For the Nine Months Ended September 30, 2023 2022 (in millions) Pre-Tax Effective Pre-Tax Effective Bermuda $ (21.1) — % $ (60.3) — % United States (31.2) (32.9) % 81.6 20.7 % United Kingdom (23.2) 30.4 % (23.9) (16.2) % Barbados — (1) — % — — % Brazil — — % (0.1) (422.4) % United Arab Emirates 0.3 — % 1.3 — % Ireland (0.1) — % (39.3) — % Italy 0.1 50.3 % (0.1) (46.4) % Malta — — % (4.1) — % Pre-tax income (loss) $ (75.2) (4.4) % $ (44.9) (47.0) % (1) Pre-tax income (loss) for the respective year was less than $0.1 million. Our effective tax rate may vary significantly from period to period depending on the jurisdiction generating the pre-tax income (loss) and its corresponding statutory tax rate. The geographic distribution of pre-tax income (loss) can fluctuate significantly between periods given the inherent nature of our business. The Company is also subject to the Base Erosion and Anti-Abuse Tax liability (“BEAT”) for certain payments made to foreign related parties. A reconciliation of the difference between the provision for income taxes and the expected tax provision at the weighted average tax rate is as follows: For the Three Months Ended For the Nine Months Ended (in millions) 2023 2022 2023 2022 Income tax provision at expected rate $ (4.1) $ (7.8) $ (11.0) $ 11.1 Tax effect of: Nontaxable investment income — (0.1) (0.1) (0.3) Foreign exchange adjustments — — (2.6) 0.8 Goodwill and Intangibles — 5.5 — 5.5 Base Erosion and Anti-Abuse Tax 20.4 — 16.9 — Withholding taxes — — 0.1 — Sale of Brazil and Malta Operations — 0.1 — 6.6 U.S. state tax expense, net of federal income tax effect — — (1.2) — Change in uncertain tax position liability — — 1.2 0.6 Change in valuation allowance 0.2 (1.3) 0.1 (6.7) Impact of change in tax rate related to Finance Act 2021 — (0.4) (0.4) 0.9 Prior period adjustment 0.2 (0.5) 0.1 0.3 Other, net 0.9 0.5 0.2 2.3 Income tax provision (benefit) $ 17.6 $ (4.0) $ 3.3 $ 21.1 . Our gross deferred tax assets are supported by taxes paid in previous periods, reversal of taxable temporary differences and recognition of future taxable income. Management regularly evaluates the recoverability of the deferred tax assets and makes any necessary adjustments to them based upon any changes in management’s expectations of future taxable income. Realization of deferred tax assets is dependent upon our generation of future taxable income sufficient to recover tax benefits that cannot be recovered from taxes paid in the carryback period, generally for our U.S. property and casualty insurers two years for net operating losses and for all our U.S. subsidiaries three years for capital losses. If a company determines that any of its deferred tax assets will not result in future tax benefits, a valuation allowance must be established for the portion of these assets that are not expected to be realized. For the three and nine months ended September 30, 2023, the net change in valuation allowance for deferred tax assets was an increase of $0.2 million and $0.1 million, respectively. Existing valuation allowances pertain to the following: Internal Revenue Code Section 382 limited net operating loss carryforwards within the United States, cumulative losses incurred since inception, and valuation allowances acquired through or related to acquisitions or disposals. Based upon a review of our available evidence, both positive and negative discussed above, our management concluded that it is more-likely-than-not that the other deferred tax assets will be realized. For any uncertain tax positions not meeting the “more-likely-than-not” recognition threshold, accounting standards require recognition, measurement and disclosure in a company’s Condensed Consolidated Financial Statements. For the three and nine months ended September 30, 2023, the Company had a net increase of uncertain tax positions in the amount of $0.0 million and $1.2 million related to federal or state income tax liability. A net increase of interest in the amount of $0.1 million and $0.3 million has been recorded in the line item Interest expense in our Condensed Consolidated Statements of Income (Loss) for the three and nine months ended September 30, 2023. No change to penalties were recorded for the three and nine months ended September 30, 2023. |

Commitments and Contingencies | Commitments and Contingencies Legal Actions Argo Group’s subsidiaries are parties to legal actions incidental to their business. As of September 30, 2023, management believes that the resolution of these matters would not materially affect our financial condition or results of operations. Federal Securities Class Action The Police & Fire Retirement System City of Detroit v. Argo Group International Holdings, Ltd., et al., No. 22-cv-8971 (S.D.N.Y.) On October 20, 2022, a securities class action lawsuit was filed in the United States District Court for the Southern District of New York against the Company and certain of its current and former officers, alleging securities fraud violations under sections 10(b) and 20(a) of the Securities Exchange Act of 1934. On January 18, 2023, U.S. District Judge Lewis A. Kaplan granted the Police and Fire Retirement System City of Detroit and the Oklahoma Law Enforcement Retirement System’s joint motion for appointment as lead plaintiff. On March 27, 2023, lead plaintiffs filed an Amended Class Action Complaint, which alleges that from June 11, 2018 through August 9, 2022, defendants made false and misleading statements concerning the Company’s reserves and underwriting standards. Defendants moved to dismiss the amended complaint on May 26, 2023. Lead plaintiffs filed an opposition to said motion on July 13, 2023, after which Defendants filed a reply on August 14, 2023. The Company is not able at this time to determine or predict the ultimate outcome of this proceeding or provide a reasonable estimate or range of estimates of the possible outcome or loss, if any, in this matter. Transaction-Related Shareholder Litigation Following the announcement of the proposed transaction with Brookfield Reinsurance Ltd. and BNRE Bermuda Merger Sub Ltd., complaints were filed in the United Stated District Court for the Southern District of New York: Stein v. Argo Group Int’l Holdings. Ltd., et al. , 1:23-cv -01947 (S.D.N.Y); O’Dell v. Argo Group Int’l Holdings, Ltd., et al. , C.A. No. 1:23-cv-1999 (S.D.N.Y.); Jones v. Argo Group Int’l Holdings. Ltd., et al. , 1:23-cv-02606 (S.D.N.Y); Ballard v. Argo Group Int’l Holdings, Ltd., et al. , 1:23-cv-02635 (S.D.N.Y); Montgomery v. Argo Group Int’l Holdings, Ltd., et al. , 1:23-cv-02749 (S.D.N.Y). The complaints each asserted violations of Section 14(a) and Section 20(a) of the Exchange Act and alleged that the proxy statement filed in connection with the proposed transaction between the Company and Brookfield Reinsurance Ltd. and BNRE Bermuda Merger Sub Ltd. omitted certain purportedly material information that rendered the proxy statement incomplete and misleading. The complaints sought, among other things, an order to enjoin the transaction unless additional disclosures were issued; and, if the transaction closes, damages. All of the complaints have been voluntarily dismissed. Contractual Commitments We have contractual commitments to invest up to $96.9 million related to our limited partnership investments at September 30, 2023, as further disclosed in Note 3, “Investments.” These commitments will be funded as required by the partnership agreements which can be called to be fulfilled at any time, not to exceed twelve years. |

Segment Reporting [Abstract] | |
Segment Information | Segment Information We are primarily engaged in underwriting property and casualty insurance. We have two ongoing reporting segments: U.S. Operations and International Operations. Additionally, we have Run-off Lines for certain products that we no longer underwrite. We consider many factors, including the nature of each segment’s insurance and reinsurance products, production sources, distribution strategies and the regulatory environment, in determining how to aggregate reporting segments. In evaluating the operating performance of our segments, we focus on core underwriting and investing results before the consideration of realized gains or losses from investments. Net investment and other gains (losses) are reported as a component of the Corporate and Other segment, as decisions regarding the acquisition and disposal of securities reside with the corporate investment function and are not under the control of the individual business segments. Identifiable assets by segment are those assets used in the operation of each segment. Revenue and income (loss) before income taxes for each segment were as follows: For the Three Months Ended For the Nine Months Ended (in millions) 2023 2022 2023 2022 Revenue: Earned premiums U.S. Operations $ 314.1 $ 329.3 $ 950.9 $ 998.5 International Operations 28.5 125.2 111.4 390.7 Run-off Lines 0.1 0.5 0.2 0.7 Total earned premiums 342.7 455.0 1,062.5 1,389.9 Net investment income U.S. Operations 33.2 23.1 84.7 68.7 International Operations 6.2 10.3 15.8 30.4 Run-off Lines 1.0 0.6 2.4 1.8 Total net investment income 40.4 34.0 102.9 100.9 Net investment and other gains (losses) (4.7) (44.7) (21.0) (119.6) Total revenue $ 378.4 $ 444.3 $ 1,144.4 $ 1,371.2 For the Three Months Ended For the Nine Months Ended (in millions) 2023 2022 2023 2022 Income (loss) before income taxes U.S. Operations $ (14.0) $ 26.6 $ (23.2) $ 113.5 International Operations (2.6) 3.3 9.3 28.6 Run-off Lines — 0.7 (1.0) (1.9) Total segment income (loss) before income taxes (16.6) 30.6 (14.9) 140.2 Corporate and Other (11.3) (19.3) (39.2) (53.5) Net investment and other gains (losses) (4.7) (44.7) (21.0) (119.6) Foreign currency exchange gains (losses) 3.3 9.1 (0.1) 16.5 Impairment of goodwill — (28.5) — (28.5) Total income (loss) before income taxes $ (29.3) $ (52.8) $ (75.2) $ (44.9) The table below presents earned premiums by geographic location for the three and nine months ended September 30, 2023 and 2022.

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation | The accompanying Condensed Consolidated Financial Statements of Argo Group International Holdings, Ltd. and its subsidiaries (“Argo Group,” “we,” “us,” “our” or the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Argo Group is an underwriter of specialty insurance products in the property and casualty market. The preparation of interim 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 at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. The major estimates reflected in our Condensed Consolidated Financial Statements include, but are not limited to, reserves for losses and loss adjustment expenses; reinsurance recoverables, including the reinsurance recoverables allowance for expected credit losses; fair value of investments and assessment of potential impairment, including the allowance for credit losses on fixed maturity securities; valuation of goodwill and our deferred tax asset valuation allowance. Actual results could materially differ from those estimates. Certain financial information that is normally included in annual Condensed Consolidated Financial Statements, including certain financial statement footnotes, prepared in accordance with GAAP, is not required for interim reporting purposes and has been condensed or omitted. These statements should be read in conjunction with the Condensed Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission ("SEC") (the “2022 Form 10-K”). |
Reclassification | Certain reclassifications have been made to financial information presented for prior years to conform to the current year’s presentation. |
Allowance for Credit Losses | Allowance for Credit Losses For fixed maturities with a decline in fair value below the 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 investment and other gains (losses) in the Condensed Consolidated Statements of Income (Loss). The allowance is limited to the difference between amortized cost and fair value. The estimated recoverable value is the present value of cash flows expected to be collected, as determined by management. The difference between fair value and amortized cost that is not associated with credit-related factors is recognized in the Condensed Consolidated Statements of Comprehensive Income (Loss). Accrued interest is excluded from the measurement of the allowance for credit losses. When determining if a credit loss has been incurred, we may consider the historical performance of the security, available market information and security specific considerations such as the priority payment of the security. In addition, inputs used in our analysis include, but are not limited to, credit ratings and downgrades, delinquency rates, missed scheduled interest or principal payments, purchase yields, underlying asset performance, collateral types, modeled default rates, modeled severity rates, call/prepayment rates, expected cash flows, industry concentrations, and potential or filed bankruptcies or restructurings. In cooperation with our investment managers, we evaluate for credit losses each quarter utilizing a bottom up review approach. At the security level, a determination is made as to whether a decline in fair value below the amortized cost basis is due to credit-related or noncredit-related factors. If we determine that all or a portion of a fixed maturity is uncollectible, the uncollectible amortized cost is written off with a corresponding reduction to the allowance for credit losses. If we collect cash flows that were previously written off, the recovery is recognized in Net investment and other gains (losses) . We also consider whether we intend to sell an available-for-sale security or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost. In these instances, a decline in fair value is recognized in Net investment and other gains (losses) in the Condensed Consolidated Statements of Income (Loss) based on the fair value of the security at the time of assessment, resulting in a new cost basis for the security. |
Disclosures about Fair Value of Financial Instruments | Disclosures About Fair Value of Financial Instruments Cash. The carrying amount approximates fair value. Investment securities, commercial mortgage loan investments, and short-term investments. See Note 3, “Investments,” for additional information. Premiums receivable and reinsurance recoverables on paid losses. The carrying value of current receivables and reinsurance recoverables on paid losses approximates fair value due to short term nature. Debt. At September 30, 2023 and December 31, 2022, the fair value of our debt instruments is determined using both Level 1 and Level 2 inputs, as previously defined in Note 3, “Investments.” We receive fair value prices for similar financial instruments being traded in active markets. These prices are determined using observable market information such as publicly traded quoted prices, and trading prices for similar financial instruments actively being traded in the current market. We have reviewed the processes used by the third-party providers for pricing the instruments and have determined that these processes result in fair values consistent with GAAP requirements. In addition, we review these prices for reasonableness, and have not adjusted any prices received from the third-party providers as of September 30, 2023 and December 31, 2022. A description of the valuation techniques we use to measure these liabilities at fair value is as follows: Senior Unsecured Fixed Rate Notes Level 1: • Our senior unsecured fixed rate notes are valued using Level 1 inputs. For these securities, we obtain fair value measurements from a third-party pricing service using quoted prices (unadjusted) in active markets at the reporting date. Junior Subordinated Debentures and Floating Rate Loan Stock Level 2: • Our trust preferred debentures, subordinated debentures and floating rate loan stock are typically valued using Level 2 inputs. For these securities, we obtain fair value measurements using quoted prices for similar securities being traded in active markets at the reporting date, as our specific debt instruments are less frequently traded. |
Fair Value Measurement | Fair Value Measurements Fair value is the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability, or in the absence of a principal market, the most advantageous market. Market participants are buyers and sellers in the principal (or most advantageous) market that are independent, knowledgeable, able to transact for the asset or liability and willing to transfer the asset or liability. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value. The inputs of these valuation techniques are categorized into three levels. • Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that can be accessed at the reporting date. We define actively traded as a security that has traded in the past seven days. • Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. We receive one quote per instrument for Level 2 inputs. • Level 3 inputs are unobservable inputs. Unobservable inputs reflect our own judgments about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. To validate the fair value of investments in the Company’s Condensed Consolidated Financial Statements, we receive prices from multiple sources including third-party pricing services and our outside investment managers. Through a comparative analysis, the Company validates the reasonableness of its valuations. These prices are determined using observable market information such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things. We have reviewed the processes used by the third-party providers for pricing the securities and have determined that these processes result in fair values consistent with GAAP requirements. In addition, we review these prices for reasonableness, and have not adjusted any prices received from the third-party providers as of September 30, 2023 and December 31, 2022. A description of the valuation techniques we use to measure assets at fair value is as follows: Fixed Maturities (Available-for-Sale) Levels 1 and 2: • United States Treasury securities are typically valued using Level 1 inputs. For these securities, we obtain fair value measurements from third-party pricing services using quoted prices (unadjusted) in active markets at the reporting date. • United States Government agencies, non-U.S. Government securities, obligations of states and political subdivisions, credit securities and foreign denominated government and credit securities are reported at fair value using Level 2 inputs. For these securities, we obtain fair value measurements from third-party pricing services. Observable data may include dealer quotes, market spreads, yield curves, live trading levels, trade execution data, credit information and the security’s terms and conditions, among other things. • Asset and mortgage-backed securities and collateralized loan obligations are reported at fair value using Level 2 inputs. For these securities, we obtain fair value measurements from third-party pricing services. Observable data may include dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things. Fixed Maturities (Available-for-Sale) Levels 3: We own term loans and asset-back securities that are valued using unobservable inputs. Equity Securities Level 1: Equity securities are principally reported at fair value using Level 1 inputs. For these securities, we obtain fair value measurements from a third-party pricing service using quoted prices (unadjusted) in active markets at the reporting date. Equity Securities Level 3: We own certain equity securities that are reported at fair value using Level 3 inputs. The valuation techniques for these securities include the following: • Fair value measurements for an investment in an equity fund obtained by applying final prices provided by the administrator of the fund, which is based upon certain estimates and assumptions. • Fair value measurements from brokers and independent valuation services, both based upon estimates, assumptions and other unobservable inputs. Other Investments Level 2: Foreign regulatory deposits are assets held in trust in jurisdictions where there is a legal and regulatory requirement to maintain funds locally in order to protect policyholders. Lloyd’s is the appointed investment manager for the funds. These assets are invested in short-term government securities, agency securities and corporate bonds and are valued using Level 2 inputs based upon values obtained from Lloyd’s. Short-term Investments: Short-term investments are principally reported at fair value using Level 1 inputs, with the exception of short-term corporate and governmental bonds reported at fair value using Level 2 inputs as described in the fixed maturities section above. Values for the investments categorized as Level 1 are obtained from various financial institutions as of the reporting date. |
