Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Amounts are presented in United States of America (“U.S.”) Dollars and all amounts are in millions, except for number of shares, per share amounts and number of securities. Certain prior period amounts have been revised 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 sheets as of December 31, 2022 and December 31, 2021; and the consolidated statements of operations, comprehensive income and changes in equity, in each case, for the years ended December 31, 2022, 2021, and 2020 is presented in Note 29. The Company will also correct previously reported financial information for such errors in its future filings, as applicable. Certain prior period amounts have also been reclassified to reflect the impacts of businesses held for sale and discontinued operations as further summarized in Note 4. Principles of Consolidation The Consolidated Financial Statements include the accounts of the Company and its controlled subsidiaries, generally through a greater than 50% ownership of voting rights and voting interests. Equity investments in entities that the Company does not consolidate, but where the Company has significant influence or where the Company has more than a minor influence over the entity’s operating and financial policies, are accounted for under the equity method. Non-controlling interest consists of equity that is not attributable directly or indirectly to the Company. All material inter-company transactions and balances are eliminated in consolidation. In order to facilitate the Company’s closing process, financial information from certain foreign subsidiaries and affiliates is reported on a one to three-month lag. Use of Estimates The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts. The items affected by the use of estimates include but are not limited to, investments, reinsurance recoverables, premium and accounts receivables, deferred acquisition costs (“DAC”), value of business acquired (“VOBA”), deferred income taxes and associated valuation allowances, goodwill, intangible assets, future policy benefits and expenses, unearned premiums, claims and benefits payable, deferred gain on disposal of businesses, pension and post-retirement liabilities and commitments and contingencies. The estimates are sensitive to market conditions, investment yields, mortality, morbidity, commissions and other acquisition expenses, policyholder behavior and other factors. Actual results could differ from the estimates recorded. The Company believes all amounts reported are reasonable and adequate. Fair Value The Company uses an exit price for its fair value measurements. An exit price is defined as the amount received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In measuring fair value, the Company gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. See Note 10 for additional information. Foreign Currency For foreign affiliates where the local currency is the functional currency, unrealized foreign currency translation gains and losses net of deferred income taxes have been reflected in accumulated other comprehensive income (“AOCI”). For Canada, Argentina, Brazil, Chile and Mexico, deferred taxes have not been provided for unrealized currency translation gains and losses since the Company intends to indefinitely reinvest the earnings in these other jurisdictions. Transaction gains and losses on assets and liabilities denominated in foreign currencies are recorded in underwriting, selling, general and administrative expenses in the consolidated statements of operations during the period in which they occur. Management generally identifies highly inflationary markets as those markets whose cumulative inflation rates over a three-year period exceeds 100%, in addition to considering other qualitative and quantitative factors. Beginning July 1, 2018, as a result of the classification of Argentina’s economy as highly inflationary, the functional currency of our Argentina subsidiaries was changed from the local currency to U.S. Dollars. The subsidiaries’ non-U.S. Dollar denominated monetary assets and liabilities have been subject to remeasurement since July 1, 2018. For the years ended December 31, 2022, 2021 and 2020, the remeasurement resulted in $16.7 million, $7.0 million and $7.5 million, respectively, of net pre-tax losses which the Company classified within underwriting, selling, general and administrative expenses in the consolidated statements of operations. Based on the relative size of the subsidiaries’ operations and net assets subject to remeasurement, the Company does not anticipate the ongoing remeasurement to have a material impact on the Company’s results of operations or financial condition. Variable Interest Entities The Company may enter into agreements with other entities that are deemed to be variable interest entities (“VIEs”). Entities that do not have sufficient equity at risk to allow the entity to finance its activities without additional financial support or in which the equity investors, as a group, do not have the characteristic of a controlling financial interest are referred to as VIEs. A VIE is consolidated by the variable interest holder that is determined to have the controlling financial interest (the “primary beneficiary”) as a result of having both the power to direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE’s capital structure, contractual terms, the nature of the VIE’s operations and purpose and the Company’s relative exposure to the related risks of the VIE on the date it becomes initially involved in the VIE. The Company only holds non-consolidated VIEs as of December 31, 2022 and 2021. Prior to the deconsolidation in the third quarter of 2020, the consolidated collateralized loan obligation (“CLO”) entities met the definition of a collateralized financing entity. Refer to Note 4 for additional information on the sale of the Company’s CLO asset management platform. Investments Fixed maturity securities are classified as available-for-sale as defined in the investments guidance and are reported at fair value. If the fair value is higher than the amortized cost for fixed maturity securities, the excess is an unrealized gain; and, if lower than amortized cost, the difference is an unrealized loss. Net unrealized gains and losses on securities classified as available-for-sale, less deferred income taxes, are included in AOCI. Presentation of credit-related impairments is shown as an allowance, recognizing credit impairments upon purchase of securities as applicable, and requiring reversals of previously recognized credit-related impairments when applicable. For available for sale fixed maturity securities in an unrealized loss position for which the Company does not intend to sell or for which it is more likely than not that the Company would not be required to sell before an anticipated recovery in value, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than the amortized cost basis, changes to the credit rating of the security by a nationally recognized statistical ratings organization and any adverse conditions specifically related to the security, industry or geographic area, among other factors. If this assessment indicates a potential credit loss may exist, the present value of cash flows expected to be collected are compared to the security’s amortized cost basis. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit-related impairment exists, and a charge to income and an associated allowance for credit losses is recorded for the credit-related impairment. Any impairment not related to credit losses is recorded through other comprehensive income. The amount of the allowance for credit losses is limited to the amount by which fair value is less than the amortized cost basis. Upon recognizing a credit-related impairment, the cost basis of the security is not adjusted. Subsequent changes in the allowance for credit losses are recorded as provision for, or reversal of, credit loss expense. For fixed maturities where the Company records a credit loss, a determination is made as to the cause of the impairment and whether the Company expects a recovery in the value. Write-offs are charged against the allowance when management concludes the financial asset is uncollectible. For fixed maturities where the Company expects a recovery in value, the effective yield method is utilized, and the investment is amortized to par. For available for sale fixed maturity securities that the Company intends to sell, or for which it is more likely than not that the Company will be required to sell before recovery of its amortized cost basis, the entire impairment loss, or difference between the fair value and amortized cost basis of the security, is recognized in net realized gains (losses) on investments and fair value changes to equity securities. The new cost basis of the security is the previous amortized cost basis less the impairment recognized and is not adjusted for any subsequent recoveries in fair value. The Company reports receivables for accrued investment income separately from fixed maturities available for sale and elected not to measure allowances for credit losses for accrued investment income as uncollectible balances are written off in a timely manner. Equity securities that have readily determinable fair values are measured at fair value with changes in fair value recognized in net realized gains (losses) on investments and fair value changes to equity securities on the Company’s consolidated statements of operations. The Company has certain equity investments that do not have readily determinable fair values and the Company has elected the measurement alternative to carry such investments at cost, less impairment and to mark to fair value when observable prices in identical or similar investments from the same issuer occur. Equity securities accounted for under the measurement alternative are impaired if a qualitative assessment based upon several indicators such as earnings performance, offers to sell or purchase, ability to continue as a going concern and macroeconomic factors indicates the equity investment is impaired and the fair value of the investment is less than its carrying value. If a qualitative assessment indicates impairment, a quantitative analysis, which uses probability weighted potential outcomes, is performed to determine the amount of the impairment to be recognized that result in a fair value measurement. Equity securities accounted for under the measurement alternative are included within Other investments in the consolidated balance sheets. Commercial mortgage loans on real estate are reported at unpaid principal balances, adjusted for amortization of premium or discount, less any allowance for credit losses. The allowance for the Company’s commercial mortgage loans is based on the present value of expected future cash flows discounted at the loan’s effective interest rate, utilizing a probability-of-default and loss given default methodologies, which incorporate various probability weighted economic scenarios. The probability of default is estimated using macroeconomic factors as well as individual loan characteristics, including loan-to-value (“LTV”) and debt service coverage ratios (“DSC”), loan term, collateral type, geography and underlying credit. The loss given default is driven primarily by the type and value of underlying collateral, and to a lesser extent by expected liquidation costs and time to recovery. Each loan is analyzed individually based on loan-specific data elements to estimate the expected loss and then aggregated. The Company places loans on nonaccrual status after 90 days of delinquent payments (unless the loans are secured and in the process of collection). A loan may be placed on nonaccrual status before this time if information is available that suggests collection is unlikely. The Company charges off loan and accrued interest balances that are deemed uncollectible. Charge offs are recorded to net income in the period deemed uncollectible. Refer to Note 5 for further details on the allowance for credit losses on commercial mortgage loans. Short-term investments include securities and other investments with durations of one year or less, but greater than three months, between the date of purchase and maturity. These amounts are reported at cost or amortized cost, which approximates fair value. Other investments consist primarily of investments in joint ventures, partnerships, equity investments that do not have readily determinable fair values, invested assets associated with a modified coinsurance arrangement, invested assets associated with the Assurant Investment Plan (the “AIP”), the American Security Insurance Company Investment Plan (the “ASIC”) and the Assurant Deferred Compensation Plan (the “ADC”), as well as policy loans. The joint ventures and partnerships are valued according to the equity method of accounting. In applying the equity method, the Company uses financial information provided by the investee, generally on a three-month lag. The invested assets related to the modified coinsurance arrangement, the AIP, the ASIC and the ADC are classified as trading securities. Policy loans are reported at unpaid principal balances, which do not exceed the cash surrender value of the underlying policies. Realized gains and losses on sales of investments are recognized on the specific identification basis. Investment income is recorded as earned and reported net of investment expenses. The Company uses the interest method to recognize interest income on its commercial mortgage loans. The Company anticipates prepayments of principal in the calculation of the effective yield for mortgage-backed securities and structured securities. The retrospective method is used to adjust the effective yield for the majority of the Company’s mortgage-backed and structured securities. For credit-sensitive structured securities, the effective yield is recalculated on a prospective basis. Cash and Cash Equivalents The Company considers all highly liquid securities and other investments with durations of three months or less between the date of purchase and maturity to be cash equivalents. These amounts are carried at cost, which approximates fair value. Cash balances are reviewed at the end of each reporting period to determine if negative cash balances exist. If negative cash balances exist, the cash accounts are netted with other positive cash accounts of the same bank provided the right of offset exists between the accounts. If the right of offset does not exist, the negative cash balances are reclassified to accounts payable and other liabilities. Restricted cash and cash equivalents, of $3.7 million and $27.9 million at December 31, 2022 and 2021, respectively, principally related to cash deposits involving insurance programs with restrictions as to withdrawal and use, are classified within cash and cash equivalents in the consolidated balance sheets. Reinsurance For both ceded and assumed reinsurance, risk transfer requirements must be met for reinsurance accounting to apply. If risk transfer requirements are not met, the contract is accounted for as a deposit, resulting in the recognition of cash flows under the contract through a deposit asset or liability and not as revenue or expense. To meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of both underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity. Similar risk transfer criteria are used to determine whether directly written insurance contracts should be accounted for as insurance or as a deposit. Reinsurance recoverables include amounts related to paid benefits and estimated amounts related to unpaid policy and contract claims, future policyholder benefits and policyholder contract deposits. The cost of reinsurance is recognized as a reduction to premiums earned over the terms of the underlying reinsured policies. Amounts recoverable from reinsurers are estimated in a manner consistent with claim and claim adjustment expense reserves or future policy benefits reserves and are reported in the consolidated balance sheets. The cost of reinsurance related to long-duration contracts is recognized over the life of the underlying reinsured policies. The ceding of insurance does not discharge the Company’s primary liability to insureds, thus a credit exposure exists to the extent that any reinsurer is unable to meet the obligation assumed in the reinsurance agreements. To mitigate this exposure to reinsurer insolvencies, the Company evaluates the financial condition of its reinsurers and typically holds collateral (in the form of funds withheld, trusts and letters of credit) as security under the reinsurance agreements. The Company accounts for credit losses using the expected credit loss model for reinsurance recoverables. The Company uses a probability of default and loss given default methodology in estimating the allowance, whereby the credit ratings of reinsurers are used in determining the probability of default. The allowance is established for reinsurance recoverables on paid and unpaid future policy benefits and claims and benefits. Prior to applying default factors, the net exposure to credit risk is reduced for any collateral for which the right of offset exists, such as funds withheld, assets held in trust and letters of credit, which are part of the reinsurance arrangements, with adjustments to include consideration of credit exposure on the collateral. The methodology used by the Company incorporates historical default factors for each reinsurer based on their credit rating using comparably rated bonds as published by a major ratings service. The allowance is based upon the Company’s ongoing review of amounts outstanding, length of collection periods, changes in reinsurer credit standing and other relevant factors. Funds held under reinsurance represent amounts contractually held from assuming companies in accordance with reinsurance agreements, primarily from collateral considerations. Reinsurance premiums assumed are calculated based upon payments received from ceding companies together with accrual estimates, which are based on both payments received and in force policy information received from ceding companies. Any subsequent differences arising on such estimates are recorded in the period in which they are determined. Premiums and Accounts Receivable Premiums and accounts receivable includes insurance premiums receivable from policyholders and amounts due from sponsors or agents. The Company accounts for credit losses using the expected credit loss model for premiums and accounts receivable. For receivables due directly from the insured or consumer, the allowance for credit losses is generally calculated by aging the receivable balances and applying default factors based on the Company’s historical collection data. For receivables due from product sponsors or agents, receivable balances are generally segregated by the sponsor or agent and an appropriate default factor is determined based on creditworthiness, billing terms and aging of balances. The financial exposure of a credit loss is determined net of offsets (such as related unearned premium reserves for consumer receivables and receivables net of commissions payable, profit share liabilities and captive reinsurance for balances due from sponsors/agents) prior to applying a default factor. Deferred Acquisition Costs Only direct and incremental costs associated with the successful acquisition of new or renewal insurance contracts are deferred to the extent that such costs are deemed recoverable from future premiums or gross profits. Acquisition costs primarily consist of commissions and premium taxes. Certain direct response advertising expenses are deferred when the primary purpose of the advertising is to elicit sales to customers who can be shown to have specifically responded to the advertising and the direct response advertising results in probable future benefits. All other acquisition-related costs, including those related to general advertising and solicitation, market research, agent training, product development, unsuccessful sales and underwriting efforts, as well as all indirect costs, are expensed as incurred. Premium deficiency testing is performed annually and generally reviewed quarterly. Such testing involves the use of assumptions including the anticipation of investment income to determine if anticipated future policy premiums are adequate to recover all DAC and related claims, benefits and expenses. To the extent a premium deficiency exists, it is recognized immediately by a charge to the consolidated statement of operations and a corresponding reduction in DAC. If the premium deficiency is greater than unamortized DAC, a loss (and related liability) is recorded for the excess deficiency. Short Duration Contracts Acquisition costs relating to extended service contracts, vehicle service contracts, mobile device protection, credit insurance, lender-placed homeowners insurance and flood, multifamily housing and manufactured housing insurance are amortized over the term of the contracts in relation to premiums earned. These acquisition costs consist primarily of advance commissions paid to agents. Property and Equipment Property and equipment are reported at cost less accumulated depreciation. Depreciation is calculated on a straight-line basis over estimated useful lives with a maximum of 39.5 years for buildings, a maximum of seven years for furniture and a maximum of five years for equipment. Expenditures for maintenance and repairs are charged to income as incurred. Expenditures for improvements are capitalized and depreciated over the remaining useful life of the asset. Property and equipment also include capitalized software costs, comprised of purchased software as well as certain internal and external costs incurred during the application development stage that directly relate to obtaining, developing or upgrading internal use software. Such costs are capitalized and amortized using the straight-line method over their estimated useful lives, not to exceed 15 years. Property and equipment are assessed for impairment when impairment indicators exist. Goodwill Goodwill represents the excess of acquisition costs over the net fair value of identifiable assets acquired and liabilities assumed in a business combination. Goodwill is deemed to have an indefinite life and is not amortized, but rather is tested at least annually for impairment. The Company performs the annual goodwill impairment test as of October 1 each year, or more frequently if indicators of impairment exist. Such indicators include: a significant adverse change in legal factors, an adverse action or assessment by a regulator, unanticipated competition, loss of key personnel or a significant decline in the Company’s expected future cash flows due to changes in company-specific factors or the broader business climate. The evaluation of such factors requires considerable management judgment. Goodwill is tested for impairment at the reporting unit level, which is either at the operating segment or one level below, if that component is a business for which discrete financial information is available and segment management regularly reviews such information. Components within an operating segment can be aggregated into one reporting unit if they have similar economic characteristics. At the time of the annual goodwill test, the Company has the option to first assess qualitative factors to determine whether it is necessary to perform a quantitative goodwill impairment test. The Company is required to perform an additional quantitative step if it determines qualitatively that it is more likely than not (likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount, including goodwill. Otherwise, no further testing is required. If the Company determines that it is more likely than not that the reporting unit’s fair value is less than the carrying value, or otherwise elects to perform the quantitative testing, the Company compares the estimated fair value of the reporting unit with its net book value. If the reporting unit’s estimated fair value exceeds its net book value, goodwill is deemed not to be impaired. If the reporting unit’s net book value exceeds its estimated fair value, an impairment loss will be recognized for the amount by which the reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill in that reporting unit. Refer to Note 15 for further details on goodwill impairment testing for 2022. Other Intangible Assets Intangible assets that have finite lives are amortized over their estimated useful lives based on the pattern in which the intangible asset is consumed, which may be other than straight-line. Estimated useful lives of finite intangible assets are required to be reassessed on at least an annual basis. For intangible assets with finite lives, impairment is recognized if the carrying amount is not recoverable and exceeds the fair value of the other intangible asset. Generally, other intangible assets with finite lives are only tested for impairment if there are indicators of impairment (“triggers”) identified. Triggers include a significant adverse change in the extent, manner or length of time in which the intangible asset is being used or a significant adverse change in legal factors or in the business climate that could affect the value of the other intangible asset. VOBA represents the value of expected future profits in unearned premium for insurance contracts acquired in an acquisition. For vehicle service contracts and extended service contracts, such as those purchased in connection with the TWG acquisition, the amount is determined using estimates, for premium earnings patterns, paid loss development patterns, expense loads and discount rates applied to cash flows that include a provision for credit risk. The amount determined represents the purchase price paid to the seller for producing the business. For vehicle service contracts and extended service contracts, VOBA is amortized consistent with the premium earning patterns of the underlying in-force contracts. For limited payment policies, preneed life insurance policies, universal life policies and annuities, VOBA is determined using estimates for mortality, lapse, maintenance expenses, investment returns and other applicable purchase assumptions at the date of purchase and is amortized over the expected life of the policies. VOBA is tested at least annually in the fourth quarter for recoverability. Amortization expense and impairment charges for other intangible assets are included in underwriting, selling, general and administrative expenses in the consolidated statements of operations. Other Assets Other assets include prepaid items, income tax receivable, deferred income tax assets, right-of-use assets, dealer loans, investments in unconsolidated entities and inventory associated with the Company’s mobile protection business. Reserves Reserves are established using generally accepted actuarial methods and reflect judgments about expected future premium and claim payments. Factors used in their calculation include experience derived from historical claim payments, expected future premiums and actuarial assumptions. Calculations incorporate assumptions about the incidence of incurred claims, the extent to which all claims have been reported, reporting lags, expenses, inflation rates, future investment earnings, internal claims processing costs and other relevant factors. The estimation of reserves includes an element of uncertainty given that management is using historical information and methods to project future events and reserve outcomes. The recorded reserves represent the Company’s best estimate at a point in time of the ultimate costs of settlement and administration of a claim or group of claims based upon actuarial assumptions and projections using facts and circumstances known at the time of calculation. The adequacy of reserves may be impacted by future trends in claims severity, frequency, judicial theories of liability and other factors. These variables are affected by both external and internal events, including: changes in the economic cycle, inflation, changes in repair costs, natural or human-made catastrophes, judicial trends, legislative changes and claims handling procedures. Many of these items are not directly quantifiable and not all future events can be anticipated when reserves are established. Reserve estimates are refined as experience develops. Adjustments to reserves, both positive and negative, are reflected in the consolidated statement of operations in the period in which such estimates are updated. Because establishment of reserves is an inherently complex process involving significant judgment and estimates, there can be no certainty that future settlement amounts for claims incurred through the financial reporting date will not vary from reported claims reserves. Future loss development could require reserves to be increased or decreased, which could have a material effect on the Company’s earnings in the periods in which such increases or decreases are made. However, based on information currently available, the Company believes its reserve estimates are adequate. The following table provides reserve information as of December 31, 2022 and 2021: December 31, 2022 December 31, 2021 Claims and Benefits Claims and Benefits Future Unearned Case Incurred Future Unearned Case Incurred Long Duration Contracts: Non-core operations (1) $ 63.5 $ — $ 1.7 $ 0.8 $ 69.3 $ — $ 5.0 $ 0.7 All other disposed or runoff businesses (2) 365.0 2.0 79.4 6.7 343.9 2.2 75.0 7.0 Short Duration Contracts: Global Lifestyle — 18,135.9 131.8 369.7 — 17,101.9 124.6 386.1 Global Housing — 1,661.2 351.0 951.3 — 1,514.3 213.4 448.3 Non-core operations (1) — — 64.3 151.0 — 1.7 52.5 60.5 All other disposed or runoff businesses (2) — 3.3 93.7 94.5 — 3.6 117.5 114.2 Total $ 428.5 $ 19,802.4 $ 721.9 $ 1,574.0 $ 413.2 $ 18,623.7 $ 588.0 $ 1,016.8 (1) Includes certain businesses which the Company expects to fully exit, including the long-tail commercial liability businesses (sharing economy and small commercial businesses) and certain legacy long-duration insurance policies (collectively referred to as “non-core operations”), recorded in the Corporate and Other segment.
