Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The Condensed Consolidated Financial Statements included herein have been prepared pursuant to the rules and regulations of the SEC and include the accounts of Kemper Corporation and its subsidiaries and are unaudited. All significant intercompany accounts and transactions have been eliminated. Certain prior year amounts for company-owned life insurance (“COLI”) have been reclassified from Other Assets to Other Investments to conform to the current presentation. Certain financial information that is normally included in annual financial statements, including certain financial statement footnote disclosures, prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) is not required by the rules and regulations of the SEC for interim financial reporting and has been condensed or omitted. In the opinion of the Company’s management, the Condensed Consolidated Financial Statements include all adjustments necessary for a fair presentation. The preparation of interim financial statements relies heavily on estimates. This factor and other factors, such as the seasonal nature of some portions of the insurance business, as well as market conditions and the impacts of COVID-19, call for caution in drawing specific conclusions from interim results. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Company’s Consolidated Financial Statements and related notes included in the 2019 Annual Report. Adoption of New Accounting Guidance Guidance Adopted in 2020 In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which replaces the existing incurred loss impairment model with an expected credit loss impairment model. The expected credit loss impairment model requires the entity to recognize its estimate of expected credit losses for affected financial assets using an allowance for credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this ASU require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected. The income statement includes the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have occurred during the period. Credit losses on available-for-sale debt securities are measured in a manner similar to prior GAAP, although ASU 2016-13 requires that they be presented as an allowance rather than as a write-down of the amortized cost. In situations where the estimate of credit loss on an available-for-sale debt security declines, entities will be able to record a reversal of the allowance to income in the current period, which was prohibited prior to the adoption of ASU 2016-13. ASU 2016-13 was adopted a modified retrospective method for financial assets measured at amortized cost as well as receivables from policyholders. Prior period amounts have not been adjusted and continue to be reported in accordance with the previous accounting guidance. A prospective transition approach is required for available-for-sale fixed maturity securities that have recognized an other-than-temporary impairment write-down prior to the effective date. The Company adopted the guidance effective January 1, 2020, which resulted in no cumulative-effect adjustment to retained earnings. In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350). To simplify the subsequent measurement of goodwill, ASU 2017-04 eliminates Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity previously had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this Update, an entity performs its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity recognizes an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. However, the loss recognized is limited to the total amount of goodwill allocated to that reporting unit. Additionally, ASU 2017-04 eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. ASU 2017-04 is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. There was no impact of the adoption of ASU 2017-04. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. ASU 2019-04 clarifies certain aspects of accounting for credit losses, hedging activities, and financial instruments, previously addressed by ASU 2016-13, Measurement of Credit Losses on Financial Instruments, ASU 2017-12, Targeted Improvements to Derivatives and Hedging Activities, and Note 1 - Basis of Presentation (continued) ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The Company adopted ASU 2017-12 in the first quarter of 2019. Accordingly, the amendments in ASU 2019-04 related to clarifications on accounting for hedging activities are effective for the Company in the first quarter of 2020. The amendments of ASU 2019-04 related to ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities , and ASU 2016-13, Measurement of Credit Losses on Financial Instruments, are effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. The impact of the adoption of ASU 2019-04 was not material. In May 2019, the FASB issued ASU 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief. ASU 2019-05 provides transition relief for entities adopting the credit loss standard, ASU 2016-13. Specifically, ASU 2019-05 amends ASU 2016-13 to allow companies to irrevocably elect, upon adoption of ASU 2016-13, the fair value option for financial instruments that are: (i) within the scope of the credit loss guidance in Accounting Standards Codification (“ASC”) Topic 326, Financial Instruments—Credit Losses ; (ii) were previously recorded at amortized cost; (iii) are eligible for the fair value option under ASC Topic 825, Financial Instruments ; and (iv) are not held to maturity debt. ASU 2019-05 is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. The Company did not elect the fair value option upon adoption of ASU 2016-13 for the financial instruments outlined above. Guidance Not Yet Adopted In August 2018, the FASB issued ASU 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to Accounting for Long-Duration Contracts . ASU 2018-12 amends the accounting model for certain long-duration insurance contracts and requires the insurer to provide additional disclosures in annual and interim reporting periods. ASU 2018-12 is effective for fiscal years beginning after December 15, 2021, and interim periods within those annual periods. The amendments in ASU 2018-12 are intended to improve measurement of the liability for future policy benefits related to nonparticipating traditional and limited-payment contracts, measurement and presentation of market risk benefits, amortization of deferred acquisition costs, and enhance presentation and disclosures. The Company is currently evaluating the impact of this guidance on its financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . ASU 2019-12 is intended to simplify accounting for income taxes by eliminating certain exceptions to the guidance in ASC Topic 740, Income Taxes , related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. Further, ASU 2019-12 clarifies that single-member limited liability companies and similar disregarded entities that are not subject to income tax are not required to recognize an allocation of consolidated income tax expense in their separate financial statements, but they could elect to do so. ASU 2019-12 is effective for annual periods beginning after December 15, 2020 and interim periods within those annual periods. The Company is currently evaluating the impact of this guidance on its financial statements. In March 2020, FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The guidance in ASU 2020-04, if elected, shall apply to contract modifications if the terms that are modified directly replace, or have the potential to replace, a reference rate with another interest rate index. If other terms are contemporaneously modified in a manner that changes, or has the potential to change, the amount or timing of contractual cash flows, the guidance in ASU 2020-04 shall apply only if those modifications are related to the replacement of a reference rate. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this guidance on its financial statements. The Company has adopted all other recently issued accounting pronouncements with effective dates prior to January 1, 2020. There were no adoptions of such accounting pronouncements during the three months ended March 31, 2020 that had a material impact on the Company’s Condensed Consolidated Financial Statements. With the exception of ASU 2018-12, Financial Services—Insurance (Topic 944):Targeted Improvements to Accounting for Long-Duration Contracts, the Company does not expect the adoption of recently issued accounting pronouncements with effective dates after March 31, 2020 to have a material impact on the Company’s financial statements and/or disclosures. Note 1 - Basis of Presentation (continued) Accounting Policies The following accounting policies have been updated effective January 1, 2020 to reflect the Company's adoption of ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments as described above . Investments in Fixed Maturities - Allowance for Expected Credit Losses For fixed maturity investments that the Company intends to sell or for which it is more likely than not that the Company will be required to sell before an anticipated recovery of value, the full amount of the impairment is reported in Impairment Losses. The Company writes down the investment’s amortized cost to its fair value, and will not adjust for any subsequent recoveries. For fixed maturity investments that the Company does not intend to sell or for which it is more likely than not that the Company will not be required to sell before an anticipated recovery of value, the Company will evaluate whether a decline in fair value below the amortized cost basis has occurred from a credit loss or other factors (non-credit related). Considerations in the credit loss assessment include (1) extent to which the fair value has been less than amortized cost, (2) conditions related to the security, an industry, or a geographic area, (3) payment structure of the investment and the likelihood of the issuer's ability to make contractual cashflows, (4) defaults or other collectability concerns related to the issuer, (5) changes in the ratings assigned by a rating agency and (6) other credit enhancements that affect the investment’s expected performance. Any increase or decrease in the expected allowance for credit losses related to investments is recognized in Impairment Losses. The expected allowance for credit losses is limited by the amount that the fair value is less than the amortized cost basis and is adjusted for any additional expected credit losses or subsequent recoveries. The amortized cost basis of the investment is not adjusted for the expected allowance for credit loss. The impairment related to other factors (non-credit related) is reported in Other Comprehensive Income, net of applicable taxes. The Company reports accrued investment income separately for available-for-sale fixed maturity securities and has elected not to measure an allowance for credit losses on accrued investment income. Accrued investment income is written off through impairment losses at the time the issuer of the bond defaults or is expected to default on interest payments. Receivables from Policyholders - Allowance for Expected Credit Losses The allowance for credit losses is a valuation account that is deducted from the receivables from policyholders based on the net amount expected to be collected on the insurance contract. Receivables from policyholders are charged off against the allowance when management believes the uncollectability of the receivable is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Management estimates the allowance using relevant available information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience on the receivables from policyholders provide the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current environmental conditions primarily unemployment rates that could impact an insureds ability to pay premiums and the anticipated impact of COVID-19.

Note 2 - Investments (continued) Investments in Mortgage- and Asset-backed Securities Not Due at a Single Maturity Date at March 31, 2020 consisted of securities issued by the Government National Mortgage Association with a fair value of $561.4 million , securities issued by the Federal National Mortgage Association with a fair value of $6.8 million , securities issued by the Federal Home Loan Mortgage Corporation with a fair value of $13.3 million and securities of other non-governmental issuers with a fair value of $761.8 million . An aging of unrealized losses on the Company’s Investments in Fixed Maturities at March 31, 2020 is presented below. Less Than 12 Months 12 Months or Longer Total (Dollars in Millions) Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses Fixed Maturities: States and Political Subdivisions 66.0 (3.9 ) 1.6 (0.2 ) 67.6 (4.1 ) Foreign Governments 2.9 (0.5 ) 2.1 (0.7 ) 5.0 (1.2 ) Corporate Securities: Bonds and Notes 888.0 (68.7 ) 30.5 (5.9 ) 918.5 (74.6 ) Redeemable Preferred Stocks 6.7 (0.1 ) — — 6.7 (0.1 ) Collateralized Loan Obligations 308.6 (51.0 ) 253.3 (40.8 ) 561.9 (91.8 ) Other Mortgage- and Asset-backed 76.8 (8.1 ) — — 76.8 (8.1 ) Total Fixed Maturities $ 1,349.0 $ (132.3 ) $ 287.5 $ (47.6 ) $ 1,636.5 $ (179.9 ) At March 31, 2020 , the Company did not have the intent to sell these investments, and it was not more likely than not that the Company would be required to sell these investments before an anticipated recovery of value. The Company considers many factors in evaluating whether the unrealized losses were credit related including, but not limited to, the extent to which the fair value has been less than amortized cost, conditions related to the security, industry, or geographic area, payment structure of the investment and the likelihood of the issuer’s ability to make contractual cashflows, defaults or other collectability concerns related to the issuer, changes in the ratings assigned by a rating agency, and other credit enhancements that affect the investment’s expected performance. The Company determined that the unrealized losses on these securities were due to non-credit related factors. Investment-grade fixed maturity investments comprised $110.7 million and below-investment-grade fixed maturity investments comprised $69.2 million of the unrealized losses on investments in fixed maturities at March 31, 2020 . For below-investment-grade fixed maturity investments in an unrealized loss position, the unrealized loss amount, on average, was approximately 17% of the amortized cost basis of the investment. An aging of unrealized losses on the Company’s Investments in Fixed Maturities at December 31, 2019 is presented below. Less Than 12 Months 12 Months or Longer Total (Dollars in Millions) Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses Fixed Maturities: U.S. Government and Government Agencies and Authorities $ 118.5 $ (1.3 ) $ 5.1 $ — $ 123.6 $ (1.3 ) States and Political Subdivisions 63.0 (0.7 ) 5.4 (0.4 ) 68.4 (1.1 ) Foreign Governments 1.0 (0.3 ) 3.1 (1.3 ) 4.1 (1.6 ) Corporate Securities: Bonds and Notes 160.0 (2.1 ) 70.7 (5.0 ) 230.7 (7.1 ) Redeemable Preferred Stocks 5.5 (0.1 ) — — 5.5 (0.1 ) Collateralized Loan Obligations 95.5 (1.9 ) 355.6 (6.6 ) 451.1 (8.5 ) Other Mortgage- and Asset-backed 72.8 (1.1 ) — — 72.8 (1.1 ) Total Fixed Maturities $ 516.3 $ (7.5 ) $ 439.9 $ (13.3 ) $ 956.2 $ (20.8 ) Note 2 - Investments (continued) Unrealized losses on fixed maturities, which the Company determined to be temporary at December 31, 2019 , were $20.8 million , of which $13.3 million was related to fixed maturities that were in an unrealized loss position for 12 months or longer. There were $0.3 million unrealized losses at December 31, 2019 related to securities for which the Company has recognized credit losses in earnings in the preceding table under the heading “Less Than 12 Months.” There were no unrealized losses at December 31, 2019 related to securities for which the Company has recognized credit losses in earnings in the preceding table under the heading “12 Months or Longer.” Investment-grade fixed maturity investments comprised $9.1 million and below-investment-grade fixed maturity investments comprised $11.7 million of the unrealized losses on investments in fixed maturities at December 31, 2019 . For below-investment-grade fixed maturity investments in an unrealized loss position, the unrealized loss amount, on average, was approximately 5% of the amortized cost basis of the investment. At December 31, 2019 , the Company did not have the intent to sell these investments, and it was not more likely than not that the Company would be required to sell these investments before recovery of its amortized cost basis, which may be at maturity. Based on the Company’s evaluation at December 31, 2019 of the prospects of the issuers, including, but not limited to, the credit ratings of the issuers of the investments in the fixed maturities, and the Company’s intention to not sell and its determination that it would not be required to sell before recovery of the amortized cost of such investments, the Company concluded that the declines in the fair values of the Company’s investments in fixed maturities presented in the preceding table were temporary at the evaluation date. Fixed Maturities - Impairment Losses The following table sets forth the change in allowance for credit losses on fixed maturities available-for-sale by major security type for three months ended March 31, 2020 . Foreign Governments Corporate Bonds and Notes Total (Dollars in Millions) Allowance for Credit Losses at Beginning of the Year $ — $ — $ — Impact of Adopting ASU 2016-13 — — — Additions for Securities for which No Previous Expected Credit Losses were Recognized 1.1 3.5 4.6 Allowance for Credit Losses at End of Period $ 1.1 $ 3.5 $ 4.6 The credit loss impairment charges included in Impairment Losses in the Condensed Consolidated Statement of Income were $4.6 million for the three months ended March 31, 2020 . Equity Securities Investments in Equity Securities at Fair Value were $709.8 million and $907.3 million at March 31, 2020 and December 31, 2019 , respectively. Net unrealized losses arising during the three months ended March 31, 2020 and recognized in earnings, related to such investments still held as of March 31, 2020 , were $112.8 million , primarily related to the recent disruption in global financial markets associated with COVID-19. For Equity Securities at Modified Cost, the Company performs a qualitative impairment analysis on a quarterly basis consisting of various factors such as earnings performance, current market conditions, changes in credit ratings, changes in the regulatory environment and other factors. If the qualitative analysis identifies the presence of impairment indicators, the Company estimates the fair value of the investment. If the estimated fair value is below the carrying value, the Company records an impairment in the Condensed Consolidated Statement of Income to reduce the carrying value to the estimated fair value. When the Company identifies observable transactions of the same or similar securities to those held by the Company, the Company increases or decreases the carrying value to the observable transaction price. The Company did not recognize any increases in the carrying value due to observable transactions. The Company recognized an impairment of $2.0 million on Equity Securities at Modified Cost for the three months ended March 31, 2020 as a result of the Company’s qualitative impairment analysis. The Company has recognized $0.5 million cumulative decreases in the carrying value due to observable transactions, no cumulative increases in the carrying value due to observable transactions and $5.0 million of cumulative impairments on Equity Securities at Modified Cost held as of March 31, 2020 . Note 2 - Investments (continued) There were no unsettled sales of Investments in Equity Securities at March 31, 2020 and December 31, 2019 . There were no unsettled purchases of Investments in Equity Securities at March 31, 2020 and December 31, 2019 . Equity Method Limited Liability Investments at Cost Plus Cumulative Undistributed Earnings Equity Method Limited Liability Investments include investments in limited liability investment companies and limited partnerships in which the Company’s interests are not deemed minor and are accounted for under the equity method of accounting. The Company’s investments in Equity Method Limited Liability Investments are generally of a passive nature in that the Company does not take an active role in the management of the investment entity. The Company’s maximum exposure to loss at March 31, 2020 is limited to the total carrying value of $226.3 million . In addition, the Company had outstanding commitments totaling approximately $89.5 million to fund Equity Method Limited Liability Investments at March 31, 2020 . At March 31, 2020 , no Equity Method Limited Liability Investments were reported without a reporting lag. 8.6% of the total carrying value were reported with a one month lag and the remainder were reported with more than a one month lag.

Actual loss experience and loss trends are likely to differ from these historical experience patterns and economic conditions. Loss experience and loss trends emerge over several years from the dates of loss inception. The Company monitors such emerging loss trends on a quarterly basis. Changes in such estimates are included in the Condensed Consolidated Statements of Income in the period of change. For the three months ended March 31, 2020 , the Company increased its property and casualty insurance reserves by $0.9 million to recognize adverse development of loss and LAE reserves from prior accident years. Specialty Personal automobile insurance loss and LAE reserves developed adversely by $18.0 million due primarily to the emergence of more adverse loss patterns than expected. Commercial automobile insurance loss and LAE reserves developed favorably by $12.5 million due primarily to the emergence of more favorable loss patterns than expected for commercial automobile liability insurance. Preferred Personal automobile insurance loss and LAE reserves developed adversely by $2.1 million due primarily to the emergence of more adverse loss patterns than expected. Homeowners loss and LAE reserves developed favorably by $5.0 million primarily due to the emergence of more favorable loss patterns than expected. Other personal lines loss and LAE reserves developed favorably by $1.8 million due primarily to the emergence of more favorable loss patterns than expected for prior accident years. For the three months ended March 31, 2019 , the Company decreased its property and casualty insurance reserves by $21.4 million to recognize favorable development of loss and LAE reserves from prior accident years. Specialty Personal automobile Note 3 - Property and Casualty Insurance Reserves (continued) insurance loss and LAE reserves developed favorably by $14.3 million due primarily to the emergence of favorable loss patterns for liability insurance related to the 2018 accident year and, to a lesser extent the 2016 and 2015 accident years. Commercial automobile loss and LAE reserves developed favorably by $3.8 million due primarily to the emergence of favorable loss patterns for liability insurance related to the 2018 accident year. Preferred Personal automobile insurance loss and LAE reserves developed favorably by $1.3 million due primarily to the emergence of favorable loss patterns for liability insurance related to 2018 and 2017 accident years. Other personal lines loss and LAE reserves developed favorably by $1.8 million due primarily to the emergence of more favorable loss patterns than expected for the 2017, 2016 and 2015 accident years. The Company cannot predict whether loss and LAE reserves will develop favorably or adversely from the amounts reported in the Company’s Condensed Consolidated Financial Statements. The Company believes that any such development will not have a material effect on the Company’s consolidated shareholders’ equity, but could have a material effect on the Company’s consolidated financial results for a given period. Receivables from Policyholders - Allowance for Expected Credit Losses The following table presents a rollforward of the receivables from policyholders, net of the allowance for expected credit losses including the changes in the allowance for expected credit losses for the three months ended March 31, 2020 .

The fair value of the collateral pledged must be maintained at certain specified levels above the borrowed amount, which can vary depending on the assets pledged. If the fair value of the collateral declines below these specified levels of the amount borrowed, United Insurance would be required to pledge additional collateral or repay outstanding borrowings. Upon any event of default by United Insurance, the FHLB’s recovery on the collateral is limited to the amount of United Insurance’s liability under the funding agreements to the FHLB of Chicago.

The Company’s investments in Equity Securities at Fair Value that are classified as Level 1 in the two preceding tables consist of either investments in publicly-traded common stocks or exchange traded funds. The Company’s investments in Fixed Maturities that are classified as Level 2 in the two preceding tables primarily consist of investments in corporate bonds, obligations of states and political subdivisions, and bonds and mortgage-backed securities of U.S. government agencies. The Company’s investments in Equity Securities at Fair Value that are classified as Level 2 in the two preceding tables primarily consist of investments in preferred stocks. The Company uses a leading, nationally recognized provider of market data and analytics to price the vast majority of the Company’s Level 2 measurements. The provider utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information. Because many fixed maturity securities do not trade on a daily basis, the provider’s evaluated pricing applications apply available information through processes such as benchmark curves, benchmarking of like securities, sector groupings and matrix pricing to prepare evaluations. In addition, the provider uses model processes to develop prepayment and interest rate scenarios. The Note 13 - Fair Value Measurements (continued) pricing provider’s models and processes also take into account market convention. For each asset class, teams of its evaluators gather information from market sources and integrate relevant credit information, perceived market movements and sector news into the evaluated pricing applications and models. The Company generally validates the measurements obtained from its primary pricing provider by comparing them with measurements obtained from one additional pricing provider that provides either prices from recent market transactions, quotes in inactive markets or evaluations based on its own proprietary models. The Company investigates significant differences related to the values provided. On completion of its investigation, management exercises judgment to determine the price selected and whether adjustments, if any, to the price obtained from the Company’s primary pricing provider would warrant classification of the price as Level 3. In instances where a measurement cannot be obtained from either pricing provider, the Company generally will evaluate bid prices from one or more binding quotes obtained from market makers to value investments in inactive markets and classified by the Company as Level 2. The Company generally classifies securities when it receives non-binding quotes or indications as Level 3 securities unless the Company can validate the quote or indication against recent transactions in the market. The table below presents quantitative information about the significant unobservable inputs utilized by the Company in determining fair values for fixed maturity investments classified as Level 3 at March 31, 2020 .

A decrease in the yield used to determine fair value will increase the fair value of the security, but the fair value increase is generally limited to par, unless callable at a premium, if the security is currently callable.

Except with regard to the matters discussed below, based on currently available information, the Company does not believe that it is reasonably possible that any of its pending legal proceedings will have a material effect on the Company’s consolidated financial statements. Over the last decade there have been an array of initiatives that intend, in various ways, to impose new duties on life insurance companies to proactively search for information related to the deaths of their insureds. These initiatives, which can include legislation, audits, regulatory examinations and related litigation, seek to alter the terms of life insurance contracts by imposing requirements that did not exist and were not contemplated at the time the issuing companies entered into such contracts. In 2016, the Company voluntarily began implementing a comprehensive process to compare the life insurance records of its life insurance subsidiaries against one or more death verification databases to determine if any of its insureds may be deceased. The initial implementation of the process is continuing. Attempts to estimate the ultimate outcomes of the aforementioned initiatives entail uncertainties including but not limited to (i) the scope and interpretation of pertinent statutes, including the matching criteria and methodologies to be used in comparing policy records against a death verification database, (ii) the universe of policies affected, (iii) the results of audits, examinations and other actions by regulators and (iv) related litigation. Gain Contingency In 2015, Kemper’s subsidiary, Kemper Corporate Services, Inc. (“KCSI”), filed a demand for arbitration with the American Arbitration Association (“AAA”) against Computer Sciences Corporation (“CSC”), claiming that CSC had breached the terms of a master software license and services agreement and related agreements (collectively, the “Agreements”) by failing, among other things, to timely produce and deliver certain software to KCSI. In April 2017, CSC merged with a spin-off of the Enterprise Services business of Hewlett Packard Enterprise Company and is now known as DXC Technology Company. In April 2017, the parties participated in an evidentiary hearing before a AAA-appointed arbitrator. Subsequently, in October 2017, the arbitrator issued a Partial Final Award finding that CSC had breached the Agreements and awarded KCSI direct damages plus pre-judgment interest. KCSI then submitted a supplemental petition providing pre-judgment interest calculations and seeking an award for certain costs and expenses. In November 2017, the arbitrator issued a Final Award awarding KCSI direct damages against CSC of $84.3 million , prejudgment interest at the annual rate of 9% and costs and expenses in the amount of $7.2 million . Note 14 - Contingencies (continued) KCSI pursued confirmation and enforcement of the Final Award in U.S. District Court in Texas. In September 2018, the Texas district court issued an Amended Final Judgment that (i) confirmed the Arbitration Award in favor of KCSI, (ii) denied CSC’s motion to vacate, and (iii) entered judgment against CSC in the total amount of $141.7 million . CSC appealed the district court’s ruling to the U.S. Court of Appeals for the Fifth Circuit. On January 10, 2020, the Fifth Circuit Court of Appeals issued a unanimous opinion affirming the district court’s ruling in favor of KCSI. During the pendency of the district court and appellate proceedings, CSC paid Kemper $35.7 million in September 2018 and an additional $20.1 million in April 2019 in partial satisfaction of the final judgment. The Company recognized such payments in Other Income in its Consolidated Statements of Income for the years ended December 31, 2018 and December 31, 2019, respectively. In February 2020, following the Fifth Circuit Court of Appeals’ ruling denying CSC’s appeal, Kemper received $89.4 million in satisfaction of the remaining balance due on the judgment. The Company recognized such payment in Other Income in its Condensed Consolidated Statement of Income for the three months ended March 31, 2020

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Beginning in March 2020, governments worldwide enacted emergency measures to combat the spread of COVID-19. These measures, which include the implementation of travel bans, self-imposed quarantine periods and social distancing, caused material disruption to businesses globally resulting in an economic slowdown. As a result, global markets continue to experience significant volatility and weakness. The Company announced that, as part of its response to the COVID-19 pandemic, personal automobile policyholders who have a policy in force as of April 30, 2020 will be credited 15% of their April 2020 premiums in May 2020, and personal automobile policyholders with a policy in force as of May 31, 2020 will be credited 15% of their May 2020 premiums in June 2020. The two premium credits will total approximately $100 million and are subject to approval from regulators. The credits will be applied directly to the policyholder's policy. If a policyholder has paid in full, the policyholder will receive a refund of the credited amounts.
