Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, these statements do not include all of the information and notes required by GAAP for complete financial statements. The interim financial data as of September 30, 2022 and for the three and nine months ended September 30, 2022 and 2021 is unaudited. In the opinion of management, the interim data includes all adjustments necessary for a fair statement of the results for the interim periods. The unaudited interim Consolidated Financial Statements include the accounts of the Company and all of its wholly owned subsidiaries. All inter-company transactions and balances are eliminated in consolidation. Certain prior period amounts have been revised to conform to the current year presentation, including the change to the segment measure of profitability described in Note 5. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The accompanying unaudited interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. Revision of Prior Period Financial Statements In second quarter 2022, the Company revised its prior period financial statements to reflect the correction of an error identified in second quarter 2022 related to reinsurance of claims and benefits payable within the Connected Living business unit in the Global Lifestyle segment occurring in late 2018 through first quarter 2022, as well as other immaterial errors which were previously recorded in the periods in which the Company identified them. A summary of revisions to the Company’s consolidated balance sheet as of December 31, 2021; and the consolidated statements of operations, comprehensive income and changes in equity, in each case, for the three and nine months ended September 30, 2021, and cash flows for the nine months ended September 30, 2021 is presented in Note 17. The Company will also correct previously reported financial information for such errors in its future filings, as applicable.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted Facilitation of the Effects of Reference Rate Reform on Financial Reporting : In March 2020, the Financial Accounting Standards Board (the “FASB”) issued guidance which provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The relief is applicable only to legacy contracts if the amendments made to the agreements are solely for reference rate reform activities. The provisions must be applied consistently for all relevant transactions other than derivatives, which may be applied at a hedging relationship level. The guidance is effective upon issuance. The guidance on contract modifications is applied prospectively from any date beginning March 12, 2020. Unlike other topics, the provisions of this update are only available until December 31, 2022, when the reference rate replacement activity is expected to have been completed. This standard is effective as of January 1, 2022, but has no impact on the Company’s consolidated financial statements as the Company currently has no contracts or hedging relationships for which the reference LIBOR or another rate is expected to be discontinued and a GAAP contract modification is required. Improvements to Convertible Instruments and Contracts in an Entity’s Own Equity : In August 2020, the FASB issued guidance that simplifies accounting for convertible instruments by removing major separation models required under current GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument and more convertible preferred stock as a single equity instrument with no separate accounting for embedded conversion features. The guidance removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more contracts in an entity’s own equity to qualify for it. The guidance also simplifies the diluted earnings per common share (“EPS”) calculation in the areas of convertible instruments and instruments that qualify for the derivatives scope exception for contracts in an entity’s own equity to address accounting for the guidance changes to the classification, recognition and measurement. This standard is effective as of January 1, 2022, but has no impact on the Company’s consolidated financial statements as the Company currently has no convertible instruments or contracts in its own equity. Not Yet Adopted Targeted improvements to the accounting for long-duration contracts : In August 2018, the FASB issued guidance that provides targeted improvements to the accounting for long-duration contracts. The guidance includes the following primary changes: assumptions supporting benefit reserves will no longer be locked-in but must be updated at least annually with the impact of changes to the liability reflected in earnings (except for discount rates); the discount rate assumptions will be based on the upper-medium grade (low credit risk) fixed-income instrument yield instead of the earnings rate of invested assets; the discount rate must be evaluated at each reporting date and the impact of changes to the liability estimate as a result of updating the discount rate assumption is required to be recognized in other comprehensive income; the provision for adverse deviation is eliminated; and premium deficiency testing is eliminated. Other noteworthy changes include the following: differing models for amortizing deferred acquisition costs will become uniform for all long-duration contracts based on a constant rate over the expected term of the related in-force contracts; all market risk benefits associated with deposit contracts must be reported at fair value with changes reflected in income except for changes related to credit risk which will be recognized in other comprehensive income; and disclosures will be expanded to include disaggregated roll forwards of the liability for future policy benefits, policyholder account balances, market risk benefits, separate account liabilities, and deferred acquisition costs, as well as information about significant inputs, judgments, assumptions and methods used in measurement. The guidance is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted. Generally, the amendments are applied retrospectively as of the beginning of the earliest period presented with two transition options available for changing the assumptions. With the sale of the disposed Global Preneed business in August 2021, the adoption of this standard is expected to have no material impact on the Company’s financial position and results of operations. Recognition and Measurement of Revenue Contracts with Customers Acquired in a Business Combination : In October 2021, the FASB issued guidance to improve comparability after a business combination is reported in the acquirer’s financial statements by providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination and revenue contracts with customers not acquired in a business combination. Generally, the acquirer will recognize the acquired contract assets and contract liabilities at the same amounts recorded by the acquiree. Historically, such amounts were recognized by the acquirer at fair value in the acquisition accounting. Under the amended guidance, the acquirer should account for the related revenue contracts as if it had originated the contracts. The amendments provide certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. The guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The amendments should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the amendment is permitted, including adoption in an interim period. An entity that early adopts in an interim period should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after the date of initial application. The adoption of this standard is expected to have no material impact on the Company’s financial position and results of operations. Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions : In June 2022, the FASB issued guidance on investments in equity securities measured at fair value that are subject to contractual restrictions preventing the sale of those securities. The amendments clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. Disclosures will be required to provide investors with information about the restriction including the fair value of the equity securities subject to any contractual sale restrictions reflected in the balance sheet, the nature and remaining duration of such restrictions, and any circumstances that could cause a lapse in such restrictions. The guidance is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The Company plans to early adopt the standard if it invests in equity securities that have contractual restrictions preventing the sale of those securities prior to the effective date. Inflation Reduction Act of 2022: In August 2022, the U.S. government enacted the Inflation Reduction Act (the “IRA”) which makes changes to the Internal Revenue Code of 1986, as amended, including the imposition of (1) a new corporate alternative minimum tax (“CAMT”) based on applicable financial statement income and (2) a 1% excise tax on corporate stock repurchases. The effective date of the IRA is January 1, 2023. After initial analysis of the IRA, the Company does not expect a material impact to the financial statements in 2022. The Company is undergoing further analysis to determine if the CAMT will apply to the financial statements in 2023 and future years. Additionally, any excise tax incurred on corporate stock repurchases is expected to be recognized as part of the cost basis of the treasury stock acquired and not reported as part of income tax expense.

Segment Reporting [Abstract]
Segment Information	Segment Information In conjunction with the transition of the Company’s CEO and chief operating decision maker on January 1, 2022, the Company changed its segment measure of profitability for its reportable segments to an Adjusted EBITDA metric, as the primary measure used for purposes of making decisions about allocating resources to the segments and assessing performance, from segment net income from continuing operations, effective as of that date. Prior period amounts have been revised to reflect the new segment measure of profitability. Beginning with second quarter 2022, the Company changed the calculation of its segment measure of profitability, Adjusted EBITDA, to exclude certain businesses which the Company expects to fully exit, including the long-tail commercial liability businesses in Global Housing (sharing economy and small commercial businesses), as well as certain legacy long-duration insurance policies within Global Lifestyle (collectively referred to as “non-core operations”), and present them as a reconciling item to consolidated net income from continuing operations. The non-core operations have been or are in the process of being exited by the Company, but do not qualify as held for sale or discontinued operations under GAAP accounting guidance. As of September 30, 2022, the Company had three reportable segments: Global Lifestyle, Global Housing and Corporate and Other. The Company defines Adjusted EBITDA as net income from continuing operations, excluding net realized gains (losses) on investments and fair value changes to equity securities, COVID-19 direct and incremental expenses, loss on extinguishment of debt, non-core operations (defined above), net income (loss) attributable to non-controlling interests, interest expense, provision (benefit) for income taxes, depreciation expense, amortization of purchased intangible assets, restructuring costs related to strategic exit activities (outside of normal periodic restructuring and cost management activities), as well as other highly variable or unusual items. All prior period amounts have been revised, which impacts both segment Adjusted EBITDA and other adjustments under reconciling items to consolidated net income from continuing operations, but does not impact consolidated net income. The sharing economy and small commercial businesses, previously reported through the Company’s Global Housing segment, generated Adjusted EBITDA of $(3.6) million and $(46.8) million for the three and nine months ended September 30, 2022, respectively, and Adjusted EBITDA of $(6.1) million and $(0.6) million for the three and nine months ended September 30, 2021, respectively. The legacy long-duration insurance policies included in non-core operations and previously reported through the Company’s Global Lifestyle segment, generated Adjusted EBITDA of $0.7 million and $1.7 million for the three and nine months ended September 30, 2022, respectively, and Adjusted EBITDA of $(2.1) million and $(2.0) million for the three and nine months ended September 30, 2021, respectively. Segment Adjusted EBITDA was also revised for an error related to reinsurance of claims and benefits payable within the Connected Living business unit in the Global Lifestyle segment, and for other unrelated immaterial errors. See Note 2 for more information. The following table presents segment Adjusted EBITDA with a reconciliation to net income attributable to common shareholders: Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Adjusted EBITDA by segment: Global Lifestyle $ 165.9 $ 176.3 $ 587.3 $ 546.0 Global Housing (25.0) 15.2 166.7 235.2 Corporate and Other (24.9) (23.0) (72.0) (67.8) Reconciling items to consolidated net income from continuing operations: Interest expense (26.3) (27.5) (80.4) (84.7) Depreciation expense (22.6) (18.1) (64.7) (52.4) Amortization of purchased intangible assets (17.3) (15.7) (51.9) (50.0) Net realized (losses) gains on investments and fair value changes to equity securities (27.4) 112.1 (166.2) 123.2 COVID-19 direct and incremental expenses (1.1) (2.0) (3.6) (7.2) Loss on extinguishment of debt — (20.7) (0.9) (20.7) Non-core operations (2.9) (8.2) (45.1) (2.6) Other adjustments (9.9) (0.2) (15.6) (6.3) Total reconciling items (107.5) 19.7 (428.4) (100.7) Income from continuing operations before income tax expense 8.5 188.2 253.6 612.7 Income tax expense 1.2 37.2 45.1 133.8 Net income from continuing operations $ 7.3 $ 151.0 $ 208.5 $ 478.9 The Company’s net earned premiums, fees and other income by segment and product are as follows: Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Global Lifestyle: Connected Living (1) $ 1,046.8 $ 1,094.1 $ 3,182.0 $ 3,221.9 Global Automotive 943.5 867.1 2,751.5 2,535.1 Total $ 1,990.3 $ 1,961.2 $ 5,933.5 $ 5,757.0 Global Housing: Lender-placed Insurance $ 262.2 $ 256.2 $ 801.9 $ 790.9 Multifamily Housing 119.9 121.7 362.0 361.2 Specialty and Other 102.0 93.2 301.9 295.5 Total $ 484.1 $ 471.1 $ 1,465.8 $ 1,447.6 (1) Effective January 1, 2022, the Connected Living line of business includes the previous Global Financial Services and Other line of business.

Revenue from Contract with Customer [Abstract]
Contract Revenues	Contract Revenues The Company partners with clients to provide consumers with a diverse range of protection products and services. The Company’s revenues from protection products are accounted for as insurance contracts and are recognized over the term of the insurance protection provided. Revenues from service contracts and sales of products are recognized as the contractual performance obligations are satisfied or the products are delivered. Revenue is measured as the amount of consideration the Company expects to be entitled to in exchange for performing the services or transferring products. If payments are received before the related revenue is recognized, the amount is recorded as unearned revenue or advance payment liabilities, until the performance obligations are satisfied or the products are transferred. The disaggregated revenues from service contracts included in fees and other income on the consolidated statements of operations are $257.9 million and $264.0 million for Global Lifestyle and $19.8 million and $22.4 million for Global Housing for the three months ended September 30, 2022 and 2021, respectively. The disaggregated revenues from service contracts included in fees and other income on the consolidated statement of operations are $825.5 million and $730.1 million for Global Lifestyle and $63.4 million and $71.8 million for Global Housing for the nine months ended September 30, 2022 and 2021, respectively. Global Lifestyle In the Company’s Global Lifestyle segment, revenues from service contracts and sales of products are primarily from the Company’s Connected Living business. Through partnerships with mobile carriers, the Company provides administrative services related to its mobile device protection products, including program design and marketing strategy, risk management, data analytics, customer support and claims handling, supply chain and service delivery, repair and logistics, and device disposition. Administrative fees are generally billed monthly based on the volume of services provided during the billing period (for example, based on the number of mobile subscribers) with payment due within a short-term period. Each service or bundle of services, depending on the contract, is an individual performance obligation with a standalone selling price. The Company recognizes revenue as it invoices, which corresponds to the value transferred to the customer. The Company also repairs, refurbishes and then sells mobile and other electronic devices, on behalf of its clients, for a bundled per unit fee. The entire processing of the device is considered one performance obligation with a standalone selling price and thus, the per unit fee is recognized when the products are sold. Payments are generally due prior to shipment or within a short-term period. Global Housing In the Company’s Global Housing segment, revenues from service contracts and sales of products are primarily from the Company’s Lender-placed Insurance business. Under the Company’s Lender-placed Insurance business, the Company provides loan and claim payment tracking services for lenders. The Company generally invoices its customers weekly or monthly based on the volume of services provided during the billing period with payment due within a short-term period. Each service is an individual performance obligation with a standalone selling price. The Company recognizes revenue as it invoices, which corresponds to the value transferred to the customer. Contract Balances The receivables and unearned revenue under these contracts were $265.9 million and $173.7 million, respectively, as of September 30, 2022, and $313.7 million and $191.5 million, respectively, as of December 31, 2021. These balances are included in premiums and accounts receivable and accounts payable and other liabilities, respectively, in the consolidated balance sheets. Revenue from service contracts and sales of products recognized during the three months ended September 30, 2022 and 2021 that was included in unearned revenue as of December 31, 2021 and 2020 was $20.0 million and $12.5 million, respectively. Revenue from service contracts and sales of products recognized during the nine months ended September 30, 2022 and 2021 that was included in unearned revenue as of December 31, 2021 and 2020 was $69.0 million and $47.6 million, respectively. In certain circumstances, the Company defers upfront commissions and other costs in connection with client contracts in excess of one year where the Company can demonstrate future economic benefit. For these contracts, expense is recognized as revenues are earned. The Company periodically assesses recoverability based on the performance of the related contracts. As of September 30, 2022 and December 31, 2021, the Company had approximately $62.3 million and $93.0 million, respectively, of such intangible assets attributed to service contracts that will be expensed over the term of the client contracts.

Approximately 76% and 94% of these gross unrealized losses had been in a continuous loss position for less than twelve months as of September 30, 2022 and December 31, 2021, respectively. The total gross unrealized losses are comprised of 3,874 and 1,202 individual securities as of September 30, 2022 and December 31, 2021, respectively. In accordance with its policy, the Company concluded that for these securities, the gross unrealized losses as of September 30, 2022 and December 31, 2021 were related to non-credit factors and therefore, did not recognize credit-related losses during the three and nine months ended September 30, 2022. Additionally, the Company currently does not intend to and is not required to sell these investments prior to an anticipated recovery in value. The Company has entered into commercial mortgage loans, collateralized by the underlying real estate, on properties located throughout the U.S. As of September 30, 2022, approximately 36% of the outstanding principal balance of commercial mortgage loans was concentrated in the states of California, Texas and Maryland. Although the Company has a diversified loan portfolio, an economic downturn could have an adverse impact on the ability of its debtors to repay their loans. The outstanding balance of commercial mortgage loans range in size from less than $0.1 million to $9.5 million as of September 30, 2022 and from $0.1 million to $9.6 million as of December 31, 2021. Credit quality indicators for commercial mortgage loans are loan-to-value and debt-service coverage ratios. The loan-to-value ratio compares the principal amount of the loan to the fair value of the underlying property collateralizing the loan, and is commonly expressed as a percentage. The debt-service coverage ratio compares a property’s net operating income to its debt-service payments and is commonly expressed as a ratio.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Disclosures Fair Values, Inputs and Valuation Techniques for Financial Assets and Liabilities Disclosures The fair value measurements and disclosures guidance defines fair value and establishes a framework for measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company has categorized its recurring fair value basis financial assets and liabilities into a three-level fair value hierarchy based on the priority of the inputs to the valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and takes into account factors specific to the asset or liability. The levels of the fair value hierarchy are described below: • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can access. • Level 2 inputs utilize other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and inputs other than quoted prices that are observable in the marketplace for the asset or liability. The observable inputs are used in valuation models to calculate the fair value for the asset or liability. • Level 3 inputs are unobservable but are significant to the fair value measurement for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability. The Company reviews fair value hierarchy classifications on a quarterly basis. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. The following tables present the Company’s fair value hierarchy for assets and liabilities measured at fair value on a recurring basis as of September 30, 2022 and December 31, 2021. The amounts presented below for short-term investments, other investments, cash equivalents, other assets, assets held in and liabilities related to separate accounts and other liabilities differ from the amounts presented in the consolidated balance sheets because only certain investments or certain assets and liabilities within these line items are measured at estimated fair value. Other investments are comprised of investments in the Assurant Investment Plan (“AIP”), the American Security Insurance Company Investment Plan, the Assurant Deferred Compensation Plan and other derivatives. Other liabilities are comprised of investments in the AIP, contingent considerations related to business combinations and other derivatives. The fair value amount and the majority of the associated levels presented for other investments and assets and liabilities held in separate accounts are received directly from third parties.

Insurance Loss Reserves [Abstract]
Reserves	Reserves Reserve Roll Forward The following table provides a roll forward of the Company’s beginning and ending claims and benefits payable balances. Claims and benefits payable is the liability for unpaid loss and loss adjustment expenses and is comprised of case and incurred but not reported (“IBNR”) reserves. Since unpaid loss and loss adjustment expenses are estimates, the Company’s actual losses incurred may be more or less than the Company’s previously developed estimates, which is referred to as either unfavorable or favorable development, respectively. The best estimate of ultimate loss and loss adjustment expense is generally selected from a blend of methods that are applied consistently each period. There have been no significant changes in the methodologies and assumptions utilized in estimating the liability for unpaid loss and loss adjustment expenses for any of the periods presented. For the Nine Months Ended September 30, 2022 2021 Claims and benefits payable, at beginning of period $ 1,604.8 $ 1,619.9 Less: Reinsurance ceded and other (825.9) (850.5) Net claims and benefits payable, at beginning of period 778.9 769.4 Incurred losses and loss adjustment expenses related to: Current year 1,728.0 1,714.8 Prior years 32.5 (30.6) Total incurred losses and loss adjustment expenses 1,760.5 1,684.2 Paid losses and loss adjustment expenses related to: Current year 1,106.2 1,158.2 Prior years 449.8 447.7 Total paid losses and loss adjustment expenses 1,556.0 1,605.9 Net claims and benefits payable, at end of period 983.4 847.7 Plus: Reinsurance ceded and other (1) 2,039.0 1,057.3 Claims and benefits payable, at end of period (1) $ 3,022.4 $ 1,905.0 (1) Includes reinsurance recoverables and claims and benefits payable of $960.4 million and $221.6 million as of September 30, 2022 and 2021, respectively, which was ceded to the U.S. government. The Company acts as an administrator for the U.S. government under the voluntary National Flood Insurance Program. The Company experienced net unfavorable loss development for the nine months ended September 30, 2022 of $32.5 million and net favorable loss development of $30.6 million for the nine months ended September 30, 2021 as presented in the roll forward table above. The unfavorable development is attributed to the sharing economy and small commercial lines of business, now reported in the Corporate and Other segment within non-core operations. Global Lifestyle contributed $42.3 million and $34.1 million to the net favorable loss development for the nine months ended September 30, 2022 and 2021, respectively. The net favorable loss development in both periods was attributable to nearly all lines of business across most of the Company’s regions with a concentration on more recent accident years and based on emerging evaluations regarding loss experience each period. For the nine months ended September 30, 2022, Global Automotive also experienced favorable loss development from ancillary products due to the strong used vehicle market. Many of these contracts and products contain retrospective commission (profit sharing) provisions that would result in offsetting increases or decreases in expense dependent on if the development was favorable or unfavorable. Global Housing contributed $22.8 million of net unfavorable loss development for the nine months ended September 30, 2022 and $0.6 million of net favorable development for the nine months ended September 30, 2021. The net unfavorable loss development for the nine months ended September 30, 2022 was comprised of $11.1 million from non-catastrophe losses and $11.7 million from prior catastrophe events. Hurricane Eta from accident year 2020 drove the unfavorable development for

Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings Per Common Share The following table presents net income, the weighted average common shares used in calculating basic EPS and those used in calculating diluted EPS for each period presented below. Diluted EPS reflects the incremental common shares from: (1) common shares issuable upon vesting of performance share units (“PSUs”) and the purchase of shares under the Employee Stock Purchase Plan (the “ESPP”) using the treasury stock method; and (2) common shares issuable upon the conversion of the MCPS using the if-converted method. The outstanding restricted stock units (“RSUs”) have non-forfeitable rights to dividend equivalents and are therefore included in calculating basic and diluted EPS under the two-class method.

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]
Retirement and Other Employee Benefits	Retirement and Other Employee Benefits The Company and its subsidiaries participate in a non-contributory, qualified defined benefit pension plan (“Assurant Pension Plan”) covering substantially all employees prior to closing to new hires on January 1, 2014. The Company also has various non-contributory, non-qualified supplemental plans covering certain employees, including the Assurant Executive Pension Plan and the Assurant Supplemental Executive Retirement Plan. The qualified and non-qualified plans are referred to as “Pension Benefits” unless otherwise noted. In addition, the Company provides certain life and health care benefits (“Retirement Health Benefits”) for retired employees and their dependents. The Pension Benefits and Retirement Health Benefits (together, the “Plans”) were frozen on March 1, 2016. In February 2020, the Company amended the Retirement Health Benefits to terminate effective December 31, 2024 (the “Termination Date”). Benefits will be paid up to the Termination Date. The Retirement Health Benefits obligations were re-measured using a discount rate of 1.55%, selected based on a cash flow analysis using a bond yield curve as of February 29, 2020, and the fair market value of the Retirement Health Benefits assets as of February 29, 2020. The remeasurement resulted in a reduction to the Retirement Health Benefits obligations of $65.6 million and a corresponding prior service credit in AOCI, which will be reclassified from AOCI as it is amortized in the net periodic benefit cost over the remaining period until the Termination Date.

Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted Facilitation of the Effects of Reference Rate Reform on Financial Reporting : In March 2020, the Financial Accounting Standards Board (the “FASB”) issued guidance which provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The relief is applicable only to legacy contracts if the amendments made to the agreements are solely for reference rate reform activities. The provisions must be applied consistently for all relevant transactions other than derivatives, which may be applied at a hedging relationship level. The guidance is effective upon issuance. The guidance on contract modifications is applied prospectively from any date beginning March 12, 2020. Unlike other topics, the provisions of this update are only available until December 31, 2022, when the reference rate replacement activity is expected to have been completed. This standard is effective as of January 1, 2022, but has no impact on the Company’s consolidated financial statements as the Company currently has no contracts or hedging relationships for which the reference LIBOR or another rate is expected to be discontinued and a GAAP contract modification is required. Improvements to Convertible Instruments and Contracts in an Entity’s Own Equity : In August 2020, the FASB issued guidance that simplifies accounting for convertible instruments by removing major separation models required under current GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument and more convertible preferred stock as a single equity instrument with no separate accounting for embedded conversion features. The guidance removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more contracts in an entity’s own equity to qualify for it. The guidance also simplifies the diluted earnings per common share (“EPS”) calculation in the areas of convertible instruments and instruments that qualify for the derivatives scope exception for contracts in an entity’s own equity to address accounting for the guidance changes to the classification, recognition and measurement. This standard is effective as of January 1, 2022, but has no impact on the Company’s consolidated financial statements as the Company currently has no convertible instruments or contracts in its own equity. Not Yet Adopted Targeted improvements to the accounting for long-duration contracts : In August 2018, the FASB issued guidance that provides targeted improvements to the accounting for long-duration contracts. The guidance includes the following primary changes: assumptions supporting benefit reserves will no longer be locked-in but must be updated at least annually with the impact of changes to the liability reflected in earnings (except for discount rates); the discount rate assumptions will be based on the upper-medium grade (low credit risk) fixed-income instrument yield instead of the earnings rate of invested assets; the discount rate must be evaluated at each reporting date and the impact of changes to the liability estimate as a result of updating the discount rate assumption is required to be recognized in other comprehensive income; the provision for adverse deviation is eliminated; and premium deficiency testing is eliminated. Other noteworthy changes include the following: differing models for amortizing deferred acquisition costs will become uniform for all long-duration contracts based on a constant rate over the expected term of the related in-force contracts; all market risk benefits associated with deposit contracts must be reported at fair value with changes reflected in income except for changes related to credit risk which will be recognized in other comprehensive income; and disclosures will be expanded to include disaggregated roll forwards of the liability for future policy benefits, policyholder account balances, market risk benefits, separate account liabilities, and deferred acquisition costs, as well as information about significant inputs, judgments, assumptions and methods used in measurement. The guidance is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted. Generally, the amendments are applied retrospectively as of the beginning of the earliest period presented with two transition options available for changing the assumptions. With the sale of the disposed Global Preneed business in August 2021, the adoption of this standard is expected to have no material impact on the Company’s financial position and results of operations. Recognition and Measurement of Revenue Contracts with Customers Acquired in a Business Combination : In October 2021, the FASB issued guidance to improve comparability after a business combination is reported in the acquirer’s financial statements by providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination and revenue contracts with customers not acquired in a business combination. Generally, the acquirer will recognize the acquired contract assets and contract liabilities at the same amounts recorded by the acquiree. Historically, such amounts were recognized by the acquirer at fair value in the acquisition accounting. Under the amended guidance, the acquirer should account for the related revenue contracts as if it had originated the contracts. The amendments provide certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. The guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The amendments should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the amendment is permitted, including adoption in an interim period. An entity that early adopts in an interim period should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after the date of initial application. The adoption of this standard is expected to have no material impact on the Company’s financial position and results of operations. Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions : In June 2022, the FASB issued guidance on investments in equity securities measured at fair value that are subject to contractual restrictions preventing the sale of those securities. The amendments clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. Disclosures will be required to provide investors with information about the restriction including the fair value of the equity securities subject to any contractual sale restrictions reflected in the balance sheet, the nature and remaining duration of such restrictions, and any circumstances that could cause a lapse in such restrictions. The guidance is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The Company plans to early adopt the standard if it invests in equity securities that have contractual restrictions preventing the sale of those securities prior to the effective date. Inflation Reduction Act of 2022: In August 2022, the U.S. government enacted the Inflation Reduction Act (the “IRA”) which makes changes to the Internal Revenue Code of 1986, as amended, including the imposition of (1) a new corporate alternative minimum tax (“CAMT”) based on applicable financial statement income and (2) a 1% excise tax on corporate stock repurchases. The effective date of the IRA is January 1, 2023. After initial analysis of the IRA, the Company does not expect a material impact to the financial statements in 2022. The Company is undergoing further analysis to determine if the CAMT will apply to the financial statements in 2023 and future years. Additionally, any excise tax incurred on corporate stock repurchases is expected to be recognized as part of the cost basis of the treasury stock acquired and not reported as part of income tax expense.

Fair Value Disclosures [Abstract]
Fair Value Hierarchy for Assets and Liabilities	The following tables present the Company’s fair value hierarchy for assets and liabilities measured at fair value on a recurring basis as of September 30, 2022 and December 31, 2021. The amounts presented below for short-term investments, other investments, cash equivalents, other assets, assets held in and liabilities related to separate accounts and other liabilities differ from the amounts presented in the consolidated balance sheets because only certain investments or certain assets and liabilities within these line items are measured at estimated fair value. Other investments are comprised of investments in the Assurant Investment Plan (“AIP”), the American Security Insurance Company Investment Plan, the Assurant Deferred Compensation Plan and other derivatives. Other liabilities are comprised of investments in the AIP, contingent considerations related to business combinations and other derivatives. The fair value amount and the majority of the associated levels presented for other investments and assets and liabilities held in separate accounts are received directly from third parties.

Roll Forward of Claims and Benefits Payable	The following table provides a roll forward of the Company’s beginning and ending claims and benefits payable balances. Claims and benefits payable is the liability for unpaid loss and loss adjustment expenses and is comprised of case and incurred but not reported (“IBNR”) reserves. Since unpaid loss and loss adjustment expenses are estimates, the Company’s actual losses incurred may be more or less than the Company’s previously developed estimates, which is referred to as either unfavorable or favorable development, respectively. The best estimate of ultimate loss and loss adjustment expense is generally selected from a blend of methods that are applied consistently each period. There have been no significant changes in the methodologies and assumptions utilized in estimating the liability for unpaid loss and loss adjustment expenses for any of the periods presented. For the Nine Months Ended September 30, 2022 2021 Claims and benefits payable, at beginning of period $ 1,604.8 $ 1,619.9 Less: Reinsurance ceded and other (825.9) (850.5) Net claims and benefits payable, at beginning of period 778.9 769.4 Incurred losses and loss adjustment expenses related to: Current year 1,728.0 1,714.8 Prior years 32.5 (30.6) Total incurred losses and loss adjustment expenses 1,760.5 1,684.2 Paid losses and loss adjustment expenses related to: Current year 1,106.2 1,158.2 Prior years 449.8 447.7 Total paid losses and loss adjustment expenses 1,556.0 1,605.9 Net claims and benefits payable, at end of period 983.4 847.7 Plus: Reinsurance ceded and other (1) 2,039.0 1,057.3 Claims and benefits payable, at end of period (1) $ 3,022.4 $ 1,905.0

Earnings Per Share [Abstract]
Net Income, Weighted Average Common Shares Used in Calculating Basic Earnings Per Common Share and Diluted EPS	The following table presents net income, the weighted average common shares used in calculating basic EPS and those used in calculating diluted EPS for each period presented below. Diluted EPS reflects the incremental common shares from: (1) common shares issuable upon vesting of performance share units (“PSUs”) and the purchase of shares under the Employee Stock Purchase Plan (the “ESPP”) using the treasury stock method; and (2) common shares issuable upon the conversion of the MCPS using the if-converted method. The outstanding restricted stock units (“RSUs”) have non-forfeitable rights to dividend equivalents and are therefore included in calculating basic and diluted EPS under the two-class method.
