Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements of Argo Group International Holdings, Ltd. (“Argo Group,” “Argo,” “we” or the “Company”) and its subsidiaries 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 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; estimates of written and earned premiums; reinsurance premium receivable; fair value of investments and assessment of potential impairment, including the allowance for credit losses on fixed maturity securities; valuation of goodwill and intangibles and our deferred tax asset valuation allowance. Actual results could differ from those estimates. Certain financial information that normally is included in annual 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 consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the Securities and Exchange Commission ("SEC") on March 15, 2021. The interim financial information as of, and for the three months ended, March 31, 2021 and 2020 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. |

Allowance for Credit Losses For fixed maturities with a decline in the fair value between 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 realized investment losses in the Statement 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 Statement 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. We evaluate for credit losses each period. 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 realized investment gains. 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 realized gains (losses) in the Statement of Income 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: (in millions) Foreign Governments Obligations of states and political subdivisions Corporate bonds Asset backed securities Total Beginning balance, January 1, 2020 $ 0.2 $ 0.1 $ 6.1 $ 0.2 $ 6.6 Additions-initial adoption of accounting standard — — — — — Securities for which allowance was not previously recorded — — 2.1 — 2.1 Securities sold during the period — — (0.4) — (0.4) Additional net increases (decreases) in existing allowance (0.1) (0.1) (0.7) (0.2) (1.1) Ending balance, March 31, 2021 $ 0.1 $ — $ 7.1 $ — $ 7.2 Total credit impairment losses included in net realized investment gains (losses) in the Consolidated Statement of Income was $1.1 million and $24.7 million for the three months ended March 31, 2021 and March 31, 2020, respectively. Investment Gains and Losses The following table presents our gross realized investment gains (losses): For the Three Months Ended (in millions) 2021 2020 Realized gains on fixed maturities and other Fixed maturities $ 5.5 $ 20.8 Other investments, including short-terms 6.0 48.2 11.5 69.0 Realized losses on fixed maturities and other Fixed maturities (1.5) (7.7) Other investments, including short-terms (9.5) (31.9) Credit losses on fixed maturities (1.1) (24.7) (12.1) (64.3) Equity securities Net realized (losses) on equity securities (1.8) (1.6) Change in unrealized gains (losses) on equity securities held at the end of the period 15.5 (39.3) Net realized gains (losses) on equity securities 13.7 (40.9) Net realized investment and other gains (losses) before income taxes 13.1 (36.2) Income tax (benefit) provision 2.6 (8.0) Net realized investment gains (losses), net of income taxes $ 10.5 $ (28.2) The cost of securities sold is based on the specific identification method.

The currency forward contracts are carried at fair value in our Consolidated Balance Sheets in “Other liabilities" and "Other assets” at March 31, 2021 and December 31, 2020, respectively. The net realized gains and (losses) are included in “Net realized investment (losses) gains” in our Consolidated Statements of (Loss) Income. The fair value of our foreign currency exchange forward contracts as of March 31, 2021 and December 31, 2020 was as follows: (in millions) March 31, 2021 December 31, 2020 Operational currency exposure $ (4.8) $ 0.4 Asset manager investment exposure 0.7 (0.2) Total return strategy 1.0 0.7 Total $ (3.1) $ 0.9 The following table represents our gross investment realized gains and losses on our foreign currency exchange forward contracts: For the Three Months Ended (in millions) 2021 2020 Realized gains Operational currency exposure $ 3.9 $ 5.4 Asset manager investment exposure 1.0 0.8 Total return strategy 8.5 25.0 Gross realized investment gains 13.4 31.2 Realized losses Operational currency exposure (9.2) (1.7) Asset manager investment exposure — (0.4) Total return strategy (7.5) (28.0) Gross realized investment losses (16.7) (30.1) Net realized investment (losses) gains on foreign currency exchange forward contracts $ (3.3) $ 1.1 Regulatory Deposits, Pledged Securities and Letters of Credit We are required to maintain assets on deposit with various regulatory authorities to support our insurance and reinsurance operations. 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) March 31, 2021 December 31, 2020 Securities on deposit for regulatory and other purposes $ 224.2 $ 227.5 Securities pledged as collateral for letters of credit and other 176.9 189.4 Securities and cash on deposit supporting Lloyd’s business 410.1 409.2 Total restricted investments $ 811.2 $ 826.1 Fair Value Measurements Fair value is 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. 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. We receive one quote per instrument for Level 1 inputs. • 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. We receive fair value prices from third-party pricing services and our outside investment managers. 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 March 31, 2021 and December 31, 2020. 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 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 measured at fair value on a recurring basis have been categorized as follows: Fair Value Measurements at Reporting Date Using (in millions) March 31, Level 1 (a) Level 2 (b) Level 3 (c) Fixed maturities U.S. Governments $ 367.2 $ 352.2 $ 15.0 $ — Foreign Governments 321.8 — 321.8 — Obligations of states and political subdivisions 194.7 — 194.7 — Corporate bonds 2,010.3 — 2,003.7 6.6 Commercial mortgage-backed securities 355.4 — 355.4 — Residential mortgage-backed securities 543.0 — 543.0 — Asset-backed securities 125.6 — 125.6 — Collateralized loan obligations 292.5 — 292.5 — Total fixed maturities 4,210.5 352.2 3,851.7 6.6 Equity securities 182.3 167.1 — 15.2 Other investments 111.2 — 111.2 — Short-term investments 482.0 470.0 11.9 0.1 $ 4,986.0 $ 989.3 $ 3,974.8 $ 21.9 (a) Quoted prices in active markets for identical assets (b) Significant other observable inputs (c) Significant unobservable inputs Fair Value Measurements at Reporting Date Using (in millions) December 31, Level 1 (a) Level 2 (b) Level 3 (c) Fixed maturities U.S. Governments $ 399.8 $ 383.5 $ 16.3 $ — Foreign Governments 294.8 — 294.8 — Obligations of states and political subdivisions 170.4 — 170.4 — Corporate bonds 1,981.8 — 1,974.8 7.0 Commercial mortgage-backed securities 339.7 — 339.7 — Residential mortgage-backed securities 508.2 — 508.2 — Asset-backed securities 122.8 — 122.8 — Collateralized loan obligations 289.6 — 289.6 — Total fixed maturities 4,107.1 383.5 3,716.6 7.0 Equity securities 176.7 159.2 — 17.5 Other investments 102.5 0.4 102.1 — Short-term investments 542.6 526.5 16.1 — $ 4,928.9 $ 1,069.6 $ 3,834.8 $ 24.5 (a) Quoted prices in active markets for identical assets (b) Significant other observable inputs (c) Significant unobservable inputs The fair value measurements in the tables above do not equal “Total investments” on our Consolidated Balance Sheets as they exclude certain other investments that are accounted for under the equity-method of accounting.

(2) Amount represents the change in reserves due to changing our participation in Syndicates 1200 and 1910. 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 unfavorable development of prior accident years’ loss and LAE reserves on each reporting segment is presented below: For the Three Months Ended (in millions) 2021 2020 U.S. Operations $ (0.4) $ 3.3 International Operations — (0.4) Run-off Lines 1.4 (0.2) Total unfavorable prior-year development $ 1.0 $ 2.7 The following describes the primary factors behind each segment’s prior accident year reserve development for the three months ended March 31, 2021 and 2020: Three months ended March 31, 2021: • U.S. Operations : Favorable development primarily in specialty lines, largely offset by unfavorable development in professional and liability lines. • International Operations : No net prior-year reserve development for the first quarter of 2021 primarily due to favorable development in property lines offset by unfavorable development in professional lines driven by an individual large claim. • Run-off Lines : Unfavorable loss reserve development in other run-off lines. Three months ended March 31, 2020: • U.S. Operations : Unfavorable development in professional lines and liability, partially offset by favorable development in specialty related to our surety business unit. • International Operations : Favorable development in property and assumed reinsurance, largely offset by unfavorable development in professional lines. • Run-off Lines : Favorable development in risk management workers compensation, partially offset by unfavorable development in other run-off lines. In the opinion of management, 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. |

Disclosures about Fair Value of Financial Instruments | Disclosures about Fair Value of Financial Instruments Cash. The carrying amount approximates fair value. Investment securities 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. Debt. At March 31, 2021 and December 31, 2020, 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 from third-party pricing services for our financial instruments as well as for similar financial instruments. 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 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 March 31, 2021 and December 31, 2020. 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 from a third-party pricing service using quoted prices for similar securities being traded in active markets at the reporting date, as our specific debt instruments are more infrequently traded. A summary of our financial instruments whose carrying value did not equal fair value is shown below: March 31, 2021 December 31, 2020 (in millions) Carrying Fair Carrying Fair Junior subordinated debentures: Trust preferred debentures $ 172.7 $ 174.5 $ 172.7 $ 173.6 Subordinated debentures 85.2 92.8 85.1 92.3 Total junior subordinated debentures 257.9 267.3 257.8 265.9 Senior unsecured fixed rate notes 140.2 147.1 140.2 146.7 Floating rate loan stock 60.2 60.8 60.7 61.0 Based on an analysis of the inputs, our financial instruments measured at fair value on a recurring basis have been categorized as follows: Fair Value Measurements at Reporting Date Using (in millions) March 31, 2021 Level 1 (a) Level 2 (b) Level 3 (c) Junior subordinated debentures: Trust preferred debentures $ 174.5 $ — $ 174.5 $ — Subordinated debentures 92.8 — 92.8 — Total junior subordinated debentures 267.3 — 267.3 — Senior unsecured fixed rate notes 147.1 147.1 — — Floating rate loan stock 60.8 — 60.8 — 475.2 147.1 328.1 — (a) Quoted prices in active markets for identical assets (b) Significant other observable inputs (c) Significant unobservable inputs Fair Value Measurements at Reporting Date Using (in millions) December 31, 2020 Level 1 (a) Level 2 (b) Level 3 (c) Junior subordinated debentures: Trust preferred debentures $ 173.6 $ — $ 173.6 $ — Subordinated debentures 92.3 — 92.3 — Total junior subordinated debentures 265.9 — 265.9 — Senior unsecured fixed rate notes 146.7 146.7 — — Floating rate loan stock 61.0 — 61.0 — 473.6 146.7 326.9 — (a) Quoted prices in active markets for identical assets (b) Significant other observable inputs (c) Significant unobservable inputs |

Shareholders' Equity | Shareholders’ Equity On February 12, 2021, our Board of Directors declared a quarterly cash dividend in the amount of $0.31 on each common share outstanding. On March 12, 2021, we paid $10.8 million to our shareholders of record on February 26, 2021. On February 12, 2021, our Board of Directors declared a quarterly cash dividend in the amount of $437.500 per share on our 7.00% Resettable Fixed Rate Preference Shares, Series A, par value of $1.00 per share, with a liquidation preference of $25,000 per share (the “Series A Preference Shares”). Holders of depositary shares, each representing a 1/1,000th interest in a Series A Preference Share (the “Depositary Shares”), received $0.437500 per Depositary Share. On March 15, 2021, we paid $2.6 million to our shareholders of record of Series A Preference Shares on February 28, 2021. On February 18, 2020, our Board of Directors declared a quarterly cash dividend in the amount of $0.31 on each common share outstanding. On March 16, 2020, we paid $10.7 million to our shareholders of record on March 2, 2020. On May 3, 2016, our Board of Directors authorized the repurchase of up to $150.0 million of our common shares (“2016 Repurchase Authorization”). The 2016 Repurchase Authorization supersedes all previous repurchase authorizations. As of March 31, 2021, availability under the 2016 Repurchase Authorization for future repurchases of our common shares was $53.3 million. We did not repurchase any common shares for the three months ended March 31, 2021. Preferred Stock Offering On July 9, 2020, the Company issued 6,000 shares of its Series A Preference Shares (equivalent to 6,000,000 Depositary Shares, each representing a 1/1,000th interest in a Series A Preference Share) with a $25,000 liquidation preference per share (equivalent to $25 per Depositary Share). Net proceeds from the sale of the Depositary Shares were approximately $144 million after deducting underwriting discounts and estimated offering expenses payable by the Company. On September 17, 2020, the Company used most of the net proceeds to repay its $125 million principal outstanding on its term loan, previously reported in the line item “Other indebtedness” on our Consolidated Balance Sheets, and intends to use the remainder of the proceeds for working capital to support continued growth in insurance operations. Dividends to the holders of the Series A Preference Shares will be payable on a non-cumulative basis only when, as and if declared by our Board of Directors or a duly authorized committee thereof, quarterly in arrears on the 15th of March, June, September, and December of each year, commencing on September 15, 2020, at a rate equal to 7.00% of the liquidation preference per annum (equivalent to $1,750 per Series A Preference Share and $1.75 per Depositary Share per annum) up to but excluding September 15, 2025. Beginning on September 15, 2025, any such dividends will be payable on a non-cumulative basis, only when, as and if declared by our Board of Directors or a duly authorized committee thereof, during each reset period, at a rate per annum equal to the Five-Year U.S. Treasury Rate as of the most recent reset dividend determination date (as described in the Company’s prospectus supplement dated July 7, 2020) plus 6.712% of the liquidation preference per annum. |

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 performance-related incentives to key employees, non-employee directors and other service providers. 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 the 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 or 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 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 March 31, 2021 and changes during the three months then ended is as follows: Shares Weighted-Average Outstanding at January 1, 2021 381,704 $ 40.67 Granted — $ — Vested and issued (88,511) $ 47.21 Expired or forfeited (59,114) $ 22.55 Outstanding at March 31, 2021 234,079 $ 42.79 The restricted shares vest over one Performance Shares We have issued to certain key employees non-vested restricted stock awards whose vesting is subject to the achievement of certain performance measures.

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 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. We do not consider Argo Group International Holdings, Ltd. to be engaged in a trade or business in the United States or the United Kingdom and, accordingly, do not expect to be subject to direct United States or United Kingdom income taxation. We have subsidiaries based in the United Kingdom that are subject to the tax laws of that country. Under current law, these subsidiaries are taxed at the applicable corporate tax rates. Certain of the United Kingdom subsidiaries are deemed to be engaged in business in the United States, and therefore, are subject to United States corporate tax in respect of a proportion of their United States underwriting business only. Relief is available against the United Kingdom tax liabilities in respect of overseas taxes paid that arise from the underwriting business. Our United Kingdom subsidiaries file separate United Kingdom income tax returns. We have subsidiaries based in the United States that are subject to United States tax laws. Under current law, these subsidiaries are taxed at the applicable corporate tax rates. Our United States subsidiaries generally file a consolidated United States federal income tax return. We also have operations in Brazil, France, Ireland, Italy, Malta, Spain, and Switzerland, which also are subject to income taxes imposed by the jurisdiction in which they operate. We have operations in Barbados and the United Arab Emirates, which are not subject to income tax under the laws of those countries. 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 months ended March 31, 2021 and 2020, pre-tax income (loss) attributable to our operations and the corresponding operations’ effective tax rates were as follows: For the Three Months Ended March 31, 2021 2020 (in millions) Pre-Tax Effective Pre-Tax Effective Bermuda $ 5.0 — % $ (25.7) — % United States 41.3 15.7 % (10.7) 25.4 % United Kingdom (18.3) 28.1 % 1.6 106.5 % Belgium — — % — (1) 68.8 % Brazil 1.6 — % 2.2 — % United Arab Emirates 0.3 — % 0.9 — % Ireland (0.1) — % — (1) — % Italy 0.9 — % 3.4 — % Malta 0.5 — % 2.6 — % Switzerland — (1) — % — (1) — % Pre-tax income (loss) $ 31.2 4.3 % $ (25.7) 3.9 % (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 inherit nature of our business. 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 (in millions) 2021 2020 Income tax provision (benefit) at expected rate $ 6.3 $ 0.8 Tax effect of: Nontaxable investment income (0.2) (0.1) Foreign exchange adjustments (0.2) (2.0) Change in uncertain tax position liability (2.4) — Change in valuation allowance (0.8) — (1) Other (1.3) 0.3 Income tax provision (benefit) $ 1.4 $ (1.0) (1) Tax effect of the adjustment for the respective year was less than $0.1 million. 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 months ended March 31, 2021, the net change in valuation allowance for deferred tax assets was a decrease of $0.8 million relating 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. 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 financial statements. For the three months ended March 31, 2021, the Company had a net release of uncertain tax positions in the amount of $2.4 million. A net release of interest in the amount of $0.5 million has been recorded in the line item “Interest expense” in our Consolidated Statements of (Loss) Income for the three months ended March 31, 2021. A net release of penalty in the amount of $0.4 million has been recorded in the line “Underwriting, acquisition and insurance expenses” in our Consolidated Statements of Income (Loss) for the three months ended March 31, 2021. Our United States subsidiaries are no longer subject to U.S. federal and state income tax examinations by tax authorities for years before 2017. Our United Kingdom subsidiaries are no longer subject to United Kingdom income tax examinations by Her Majesty’s Revenue and Customs for years before 2019. Numerous foreign jurisdictions in which we operate have provided or proposed income-tax relief in response to the COVID-19 pandemic. The Company does not anticipate any of the recent legislative initiatives to have a material impact on its financial statements and will continue to analyze these initiatives in response to the COVID-19 pandemic. |

Segment Reporting [Abstract] | |
Segment Information | Segment Information We are primarily engaged in underwriting property and casualty insurance and reinsurance. We have two ongoing reporting segments: U.S. Operations and International Operations. Additionally, we have a Run-off Lines segment 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. Transactions between segments are reported in the segment that initiated the transaction. 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. Realized investment gains 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 (loss) income before income taxes for each segment were as follows: For the Three Months Ended (in millions) 2021 2020 Revenue: Earned premiums U.S. Operations $ 314.4 $ 302.5 International Operations 151.5 132.3 Run-off Lines 0.2 0.2 Total earned premiums 466.1 435.0 Net investment income U.S. Operations 28.8 25.2 International Operations 12.0 8.6 Run-off Lines 0.8 1.2 Corporate and Other 2.8 0.6 Total net investment income 44.4 35.6 Net realized investment (losses) gains 13.1 (36.2) Total revenue $ 523.6 $ 434.4 For the Three Months Ended (in millions) 2021 2020 Income (loss) before income taxes U.S. Operations $ 36.6 $ 36.9 International Operations (11.8) (12.3) Run-off Lines 0.6 0.5 Total segment income (loss) before taxes 25.4 25.1 Corporate and Other (6.0) (13.7) Net realized investment and other (losses) gains 13.1 (36.2) Foreign currency exchange (losses) gains (1.3) (0.9) Total (loss) income before income taxes $ 31.2 $ (25.7) The table below presents earned premiums by geographic location for the three months ended March 31, 2021 and 2020.

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements of Argo Group International Holdings, Ltd. (“Argo Group,” “Argo,” “we” or the “Company”) and its subsidiaries 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 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; estimates of written and earned premiums; reinsurance premium receivable; fair value of investments and assessment of potential impairment, including the allowance for credit losses on fixed maturity securities; valuation of goodwill and intangibles and our deferred tax asset valuation allowance. Actual results could differ from those estimates. Certain financial information that normally is included in annual 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 consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the Securities and Exchange Commission ("SEC") on March 15, 2021. |
