Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements of State Auto Financial Corporation and Subsidiaries (“State Auto Financial” or the “Company”) have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. In the opinion of the Company, all adjustments (consisting of normal, recurring accruals) considered necessary for a fair statement have been included. Operating results for the three and nine months ended September 30, 2021, are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The balance sheet at December 31, 2020, has been derived from the audited financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”). Capitalized terms used herein and not otherwise defined shall have the meaning ascribed to them in the 2020 Form 10-K. Adoption of Recent Accounting Pronouncements Income Taxes - Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12 which updated guidance for the accounting for income taxes. The updated guidance is intended to simplify the accounting for income taxes by removing several exceptions contained in existing guidance and amending other existing guidance to simplify several other income tax accounting matters. The guidance became effective for annual and interim reporting periods after December 15, 2020. On January 1, 2021, the Company adopted this guidance and it did not have a material impact on the Company's results of operations, consolidated financial position or cash flows. Pending Adoption of Recent Accounting Pronouncements For information regarding other accounting pronouncements that the Company has not yet adopted, see the “Pending Adoption of Recent Accounting Pronouncements” section of Note 1 of the Notes to Consolidated Financial Statements in the 2020 Form 10-K. |

Commitments and Contingencies Disclosure [Abstract] | |
Contingencies and Litigation | Contingencies and LitigationIn accordance with the Contingencies Topic of the FASB's Accounting Standards Codification, the Company accrues for a litigation-related liability when it is probable that such a liability has been incurred and the amount can be reasonably estimated. The Company reviews all litigation on an ongoing basis when making accrual and disclosure decisions. For certain legal proceedings, the Company cannot reasonably estimate a loss or a range of loss, if any, particularly for proceedings that are in their early stages of development or where the plaintiffs seek indeterminate damages. Various factors, including, but not limited to, the outcome of potentially lengthy discovery and the resolution of important factual questions, may need to be determined before probability can be established or before a loss or range of loss can be reasonably estimated. If the loss contingency in question is not both probable and reasonably estimable, the Company does not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. Based on currently available information known to the Company, it believes that its reserves for litigation-related liabilities are reasonable. However, in the event that a legal proceeding results in a substantial judgment against, or settlement by, the Company, there can be no assurance that any resulting liability or financial commitment would not have a material adverse effect on the financial condition, results of operations or cash flows of the consolidated financial statements of the Company. The Company is involved in lawsuits in the ordinary course of its business arising out of or otherwise related to its insurance policies. Additionally, from time to time the Company may be involved in lawsuits, including class actions, in the ordinary course of business but not arising out of or otherwise related to its insurance policies. Recently, these proceedings have included claims and lawsuits seeking coverage under commercial property policies for pure economic losses related to COVID-19. These lawsuits are in various stages of development, in various jurisdictions, and the Company intends to vigorously contest these matters. Based on currently available information, the Company does not believe that any such lawsuits will have a material adverse effect on its consolidated financial position, results of operations, or cash flows. However, the Company cannot provide assurance that it will not be negatively impacted by adverse legislation or adverse judicial rulings in some of these matters. Future court decisions and interpretations, as well as future changes, if any, in legislation could create uncertainties and additional liabilities may arise which could have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows. Additionally, the Company may be impacted by adverse regulatory actions and adverse court decisions where insurance coverages are expanded beyond the scope originally contemplated in its insurance policies. The Company believes that the effects, if any, of such regulatory actions and published court decisions are not likely to have a material adverse effect on its consolidated financial position, results of operations or cash flows. |

The decline in fair values was attributable to changes in interest rates and not credit quality. The Company does not intend to sell these securities and it is likely that it will not do so before their anticipated recovery. Therefore, the Company does not consider these impaired securities. • Corporate securities: Corporations in various industries issued these securities. The decline in fair values was attributable to changes in interest rates and not credit quality. The Company reviewed the issuers of these securities to identify any significant adverse change in financial condition, a change in the quality of credit enhancement (if any), a ratings decrease, or negative outlook assignment from a major credit rating agency, and any failure to make interest or principal payments. After these reviews, the Company determined that the decline in fair values was attributable to changes in interest rates and not credit quality. The Company does not intend to sell these securities and it is likely that it will not do so before their anticipated recovery. Therefore, the Company does not consider these impaired securities. • U.S. government agencies mortgage-backed securities: Federal government-sponsored entities issued these securities. The decline in fair values was attributable to changes in interest rates and not credit quality. The Company does not intend to sell these securities and it is likely that it will not do so before their anticipated recovery. Therefore, the Company does not consider these impaired securities. The Company regularly monitors its available-for-sale fixed maturities that have fair values less than cost or amortized cost for signs of impairment, an assessment that requires significant management judgment regarding the evidence known. Such judgments could change in the future as more information becomes known, which could negatively impact the amounts reported. Among the factors that management considers for fixed maturity securities are the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. When a fixed maturity has been determined to have an impairment, the impairment charge representing the credit loss is recognized in earnings as a realized loss and on the balance sheet as an allowance for credit losses netted with the amortized cost of fixed maturities. Future increases in fair value, if related to credit factors, are recognized through earnings limited to the amount previously recognized as an allowance for credit losses. The amount related to non-credit factors is recognized in accumulated other comprehensive income and future increases or decreases in fair value, if not credit losses, are included in accumulated other comprehensive income. The following table sets forth the amortized cost and fair value of available-for-sale fixed maturities by contractual maturity at September 30, 2021: ($ millions) Amortized cost Fair Due in 1 year or less $ 141.6 $ 142.7 Due after 1 year through 5 years 592.3 614.4 Due after 5 years through 10 years 211.7 218.2 Due after 10 years 516.7 548.6 U.S. government agencies mortgage-backed securities 697.3 699.6 Total $ 2,159.6 $ 2,223.5 Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay the obligations with or without call or prepayment penalties. At September 30, 2021, State Auto P&C had U.S. government agencies mortgage-backed fixed maturity securities, with a carrying value of approximately $106.5 million pledged as collateral for loans from the Federal Home Loan Bank of Cincinnati ("FHLB"). In accordance with the terms of the FHLB Loans, State Auto P&C retains all rights regarding these pledged securities. At September 30, 2021, State Auto P&C had fixed maturities with fair values of approximately $33.7 million pledged as collateral for the performance obligations under its reinsurance agreement with Home State County Mutual Insurance Company. In accordance with the terms of the trust agreement, State Auto P&C retains all rights regarding these securities, which are included in the “U.S. treasury securities and obligations of U.S. government agencies” classification of the Company’s fixed maturity securities portfolio. Fixed maturities with fair values of $9.6 million and $9.7 million were on deposit with insurance regulators as required by law at September 30, 2021, and December 31, 2020, respectively. The Company retains all rights regarding these securities.

Fair Value Disclosures [Abstract] | |
Fair Value of Financial Instruments | Fair Value of Financial Instruments Below is the fair value hierarchy that categorizes into three levels the inputs to valuation techniques that are used to measure fair value: • Level 1 includes observable inputs which reflect quoted prices for identical assets or liabilities in active markets at the measurement date. • Level 2 includes observable inputs for assets or liabilities other than quoted prices included in Level 1, and it includes valuation techniques which use prices for similar assets and liabilities. • Level 3 includes unobservable inputs which reflect the reporting entity’s estimates of the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). The Company utilizes a nationally recognized third party pricing service to estimate the majority of its investment portfolio’s fair value. The Company obtains one price per security and the processes and control procedures employed by the Company are designed to ensure the value is accurately recorded on an unadjusted basis. Through discussions with the pricing service, the Company gains an understanding of the methodologies used to price the different types of securities, that the data and the valuation methods utilized are appropriate and consistently applied, and that the assumptions are reasonable and representative of fair value. To validate the reasonableness of the valuations obtained from the pricing service, the Company compares to fair value pricing information gathered from other independent pricing sources. At September 30, 2021, and December 31, 2020, the Company did not adjust any of the prices received from the pricing service. Fixed Maturities The Company utilizes a nationally recognized third party pricing service to estimate fair value measurements for the majority of its fixed maturities. The fair value estimate of the Company’s fixed maturity investments are determined by evaluations that are based on observable market information rather than market quotes. Inputs to the evaluations include, but are not limited to, market prices from recently completed transactions and transactions of comparable securities, interest rate yield curves, credit spreads, and other market-observable information. The fixed maturity portfolio pricing obtained from the pricing service is reviewed for reasonableness. The Company regularly selects a sample of security prices which are compared to one or more alternative pricing sources for reasonableness. Any significant discrepancies with the pricing are returned to the pricing service for further explanation and, if necessary, adjustments are made. To date, the Company has not identified any significant discrepancies in the pricing provided by its third party pricing service. Investments valued using these inputs include U.S. treasury securities and obligations of U.S. government agencies, obligations of states and political subdivisions, corporate securities (except for a security discussed below), and U.S. government agencies' mortgage-backed securities. All unadjusted estimates of fair value for fixed maturities priced by the pricing service are included in the amounts disclosed in Level 2 of the hierarchy. If market inputs are unavailable, then no fair value is provided by the pricing service. For these securities, fair value is determined either by requesting brokers who are knowledgeable about these securities to provide a quote; or the Company internally determines the fair values by employing widely accepted pricing valuation models, and depending on the level of observable market inputs, renders the fair value estimate as Level 2 or Level 3. Equities The fair value of each equity security is based on an observable market price for an identical asset in an active market and is priced by the same pricing service discussed above. All equity securities are recorded using unadjusted market prices and have been disclosed in Level 1. Other Invested Assets Included in other invested assets is one international fund (“the fund”) that invests in equity securities of foreign issuers and is managed by a third party investment manager. The fund had a fair value of $62.2 million and $55.8 million at September 30, 2021, and December 31, 2020, respectively, which was determined using the fund’s net asset value. The Company employs procedures to assess the reasonableness of the fair value of the fund, including obtaining and reviewing the fund’s audited financial statements. There are no unfunded commitments related to the fund. The Company may not sell its investment in the fund; however, the Company may redeem all or a portion of its investment in the fund at net asset value per share with the appropriate prior written notice. In accordance with ASC 820-10, this investment is measured at fair value using the net asset value per share practical expedient and has not been classified in the fair value hierarchy. Fair values presented here are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the condensed consolidated balance sheets. The remainder of the Company’s other invested assets consist primarily of holdings in publicly-traded mutual funds. The Company believes that its prices for these publicly-traded mutual funds, which are each based on an observable market price for an identical asset in an active market reflect their fair values and consequently these securities have been disclosed in Level 1. The following tables set forth the Company’s investments within the fair value hierarchy at September 30, 2021 and December 31, 2020: ($ millions) Total Level 1 Level 2 September 30, 2021 Available-for-sale fixed maturities: U.S. treasury securities and obligations of U.S. government agencies $ 508.0 $ — $ 508.0 Obligations of states and political subdivisions 492.9 — 492.9 Corporate securities 523.0 — 523.0 U.S. government agencies mortgage-backed securities 699.6 — 699.6 Total available-for-sale fixed maturities 2,223.5 — 2,223.5 Equity securities: Large-cap securities 163.5 163.5 — Mutual and exchange traded funds 212.5 212.5 — Total equity securities 376.0 376.0 — Other invested assets 17.1 17.1 — Total investments $ 2,616.6 $ 393.1 $ 2,223.5 ($ millions) Total Level 1 Level 2 December 31, 2020 Available-for-sale fixed maturities: U.S. treasury securities and obligations of U.S. government agencies $ 551.7 $ — $ 551.7 Obligations of states and political subdivisions 541.5 — 541.5 Corporate securities 483.3 — 483.3 U.S. government agencies mortgage-backed securities 660.7 — 660.7 Total available-for-sale fixed maturities 2,237.2 — 2,237.2 Equity securities: Large-cap securities 134.2 134.2 — Mutual and exchange traded funds 255.5 255.5 — Total equity securities 389.7 389.7 — Other invested assets 15.3 15.3 — Total investments $ 2,642.2 $ 405.0 $ 2,237.2 The following sections describe the valuation methods used by the Company for each type of financial instrument it holds that is not measured at fair value but for which fair value is disclosed: Financial Instruments Disclosed, But Not Carried, At Fair Value Other Invested Assets, at Cost Included in other invested assets, at cost are common stock of the FHLB and the Trust Securities. The Trust Securities and FHLB common stock are carried at cost, which approximates fair value. The fair value of the FHLB common stock at September 30, 2021, was $9.9 million and the fair value of the Trust Securities was $0.5 million. The investments have been placed in Level 3 of the fair value hierarchy. Notes Receivable from Affiliate The Company has two separate credit agreements with State Automobile Mutual Insurance Company (“State Auto Mutual") pursuant to which it loaned State Auto Mutual a total of $70.0 million at an interest rate of 4.05%, with principal payable in May 2029. The Company estimates the fair value of the notes receivable from affiliate using market quotations for U.S. treasury securities with similar maturity dates and applies an appropriate credit spread. Consequently this has been placed in Level 2 of the fair value hierarchy. ($ millions, except interest rates) September 30, 2021 December 31, 2020 Carrying value Fair value Interest rate Carrying value Fair Interest rate Notes receivable from affiliate, issued May 2019 $ 70.0 $ 77.4 4.05 % $ 70.0 $ 80.4 4.05 % Notes Payable Included in notes payable are the FHLB Loans and Subordinated Debentures. The Company estimates the fair value of the FHLB Loans by discounting cash flows using a borrowing rate currently available to the Company for loans with similar terms. The FHLB Loans have been placed in Level 3 of the fair value hierarchy. The carrying amount of the Subordinated Debentures approximates its fair value as the interest rate adjusts quarterly and has been disclosed in Level 3.

Favorable development of prior accident years' non-catastrophe loss and ALAE reserves for the nine months ended September 30, 2021 was $45.5 million, driven by favorable development of $47.7 million in the commercial insurance segment. In the commercial insurance segment, workers' compensation and middle market commercial contributed $21.8 million and $14.7 million, respectively, of favorable development. For the nine months ended September 30, 2020, favorable development of prior accident year's non-catastrophe loss and ALAE reserves was $31.8 million, due to favorable development in the commercial insurance segment. In the commercial insurance segment, all lines contributed favorable development, with small commercial package, workers' compensation and middle market commercial contributing $16.5 million, $16.1 million and $14.3 million, respectively. Partially offsetting the favorable development was adverse development in the personal insurance segment and specialty run-off, which contributed $20.2 million and $5.2 million, respectively. The adverse development in the personal insurance segment was primarily driven by personal auto, which contributed $19.1 million of adverse development. The personal auto adverse development was driven by higher than expected severity of bodily injury claims and higher than expected frequency of property damage claims, primarily from the 2019 accident year. The specialty run-off adverse development primarily relates to an adverse court decision relating to an E&S casualty claim from 2016. Partially offsetting the favorable development of prior years' non-catastrophe loss and ALAE reserves was adverse development in catastrophe loss and ALAE reserves driven by $12.4 million of adverse development in E&S property related to Hurricane Irma. |

Income Taxes | Income Taxes Interim Period Tax Expense Due to the variability of our operating results, we determined using an estimated full year 2021 effective tax rate to determine interim period tax expense(benefit) produces an income tax benefit and effective rate that would not be meaningful for investors. Accordingly, the Company calculated a year to date tax benefit based on the year to date loss before federal income taxes using the U.S. Federal statutory tax rate and adjusted for the estimated impact of permanent differences and discrete items.

Segment Reporting [Abstract] | |
Segment Information | Segment Information The Company's reportable segments are: personal insurance, commercial insurance, and investment operations. The reportable insurance segments are business units managed separately because of the differences in the type of customers they serve, the products they provide or services they offer. The insurance segments market a broad line of property and casualty insurance products throughout the United States through independent insurance agencies, which include retail agents and wholesale brokers. The investment operations segment, managed by Stateco, provides investment services. The Company evaluates the performance of its insurance segments using industry financial measurements based on Statutory Accounting Practices (“SAP”), which include loss and loss adjustment expense ratios, underwriting expense ratios, combined ratios, statutory underwriting gain (loss), net premiums earned and net written premiums. One of the most significant differences between SAP and GAAP is that SAP requires all underwriting expenses to be expensed immediately and not deferred and amortized over the same period the premium is earned. The investment operations segment is evaluated based on investment returns of assets managed by Stateco. Asset information by segment is not reported for the insurance segments because the Company does not produce such information internally. The following table sets forth financial information regarding the Company’s reportable segments and specialty run-off (for the previously exited specialty insurance business) for the three and nine months ended September 30, 2021 and 2020: ($ millions) Three months ended September 30 Nine months ended September 30 2021 2020 2021 2020 Revenue from external sources: Insurance operations Personal insurance $ 217.2 $ 208.8 $ 638.1 $ 609.7 Commercial insurance 164.4 144.4 470.7 414.7 Specialty run-off 0.2 — (1.2) — Total insurance operations 381.8 353.2 1,107.6 1,024.4 Investment operations Net investment income 17.0 17.9 52.3 54.5 Net investment (loss) gain (8.1) 20.0 56.8 (39.3) Total investment operations 8.9 37.9 109.1 15.2 All other 0.4 0.5 1.3 1.6 Total revenue from external sources 391.1 391.6 1,218.0 1,041.2 Intersegment revenue 1.6 1.5 4.8 4.6 Total revenue 392.7 393.1 1,222.8 1,045.8 Reconciling items: Eliminate intersegment revenue (1.6) (1.5) (4.8) (4.6) Total consolidated revenues $ 391.1 $ 391.6 $ 1,218.0 $ 1,041.2 Segment (loss) income before federal income tax: Insurance operations SAP underwriting (loss) gain Personal insurance $ (21.0) $ (30.7) $ (114.6) $ (70.8) Commercial insurance (2.7) 14.4 3.1 (28.0) Specialty run-off — (10.4) 0.2 (17.1) Total insurance operations (23.7) (26.7) (111.3) (115.9) Investment operations Net investment income 17.0 17.9 52.3 54.5 Net investment (loss) gain (8.1) 20.0 56.8 (39.3) Total investment operations 8.9 37.9 109.1 15.2 All other — — — 0.1 Total segment (loss) income before reconciling items (14.8) 11.2 (2.2) (100.6) Reconciling items: GAAP expense adjustments 3.1 5.6 7.5 20.2 Interest expense on corporate debt (1.1) (1.1) (3.3) (3.6) Corporate expenses (12.9) (0.9) (17.9) (3.6) Total reconciling items (10.9) 3.6 (13.7) 13.0 Total consolidated (loss) income before federal income tax $ (25.7) $ 14.8 $ (15.9) $ (87.6) Investable assets attributable to the Company’s investment operations segment totaled $2,805.3 million and $2,870.8 million at September 30, 2021, and December 31, 2020, respectively. |
