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 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, 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 2018 Annual Report. Adoption of New Accounting Guidance Guidance Adopted in 2019 Effective January 1, 2019, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-02, Leases—(Topic 842). ASU 2016-02 introduced a lessee model that requires the recognition of a right-of-use (“ROU”) asset and a lease liability for all leases with terms greater than twelve months. The Company adopted ASU 2016-02 using the modified retrospective method at the beginning of the period of the adoption and elected the permitted practical expedients to not reassess whether any expired or existing contracts contain leases, the lease classification for any expired or existing leases and initial direct costs for any existing leases. The adoption of ASU 2016-02 had no impact on the Company’s Shareholders’ Equity as of January 1, 2019, but resulted in the establishment of a ROU asset of $66.5 million , a lease liability of $82.5 million and an adjustment to deferred rent liability of $16.0 million . The ROU Asset and related liabilities were included in Other Assets and Accrued Expenses and Other Liabilities, respectively, on the Condensed Consolidated Balance Sheets as of September 30, 2019 . In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Derivatives and Hedging Activities. ASU 2017-12 aligns an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The amendments in ASU 2017-12 expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. Furthermore, the amendments make certain targeted improvements to simplify the application of hedge accounting guidance and ease the administration of hedge documentation requirements and assessing hedge effectiveness. ASU 2017-12 is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods with early adoption permitted. The impact of adoption of ASU 2017-12 on the Company’s consolidated financial position was not material. In August 2018, the SEC issued Final Rule Release No. 33-10532, “ Disclosure Update and Simplification, ” which made a number of changes meant to simplify interim disclosures. The new rule required a presentation of changes in stockholders’ equity in the form of a reconciliation, either as a separate financial statement or in the notes to the financial statements, for the current and comparative year-to-date interim periods. In July 2019, the FASB issued ASU 2019-07, “Codification Updates to SEC Sections - Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231 and 33-10442, Investment Company Reporting Modernization and Miscellaneous Updates (SEC Update) .” ASU 2019-07 codifies Final Rule Release No. 33-10532 and is effective immediately. The additional elements of this release did not have a material impact on our overall Condensed Consolidated Financial Statements. The Company adopted the new disclosure requirements in our Form 10-Q for the period ended September 30, 2019. Note 1 - Basis of Presentation (continued) Guidance Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with a methodology that utilizes expected credit losses to provide for an allowance for credit losses for certain financial instruments 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 taken place during the period. Credit losses on available-for-sale debt securities are measured in a manner similar to current GAAP, although ASU 2016-13 requires that they be presented as an allowance rather than as a write-down. In situations where the estimate of credit loss on an available-for-sale debt security declines, entities will be able to record the reversal to income in the current period, which GAAP currently prohibits. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods with early adoption permitted for fiscal years beginning after December 31, 2018 and interim periods within such year. The Company is currently evaluating the impact of this guidance on its financial statements. 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 January 1, 2022. 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 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 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 Company is currently evaluating the impact of this guidance on its financial statements. 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 portions of the declines in the fair values of fixed maturity investments that are determined to be other than temporary are reported as losses in the Condensed Consolidated Statements of Income in the periods when such determinations are made. Unrealized losses on fixed maturities, which the Company has determined to be temporary at September 30, 2019 , were $21.6 million , of which $11.9 million was related to fixed maturities that were in an unrealized loss position for 12 months or longer. There were $0.2 million of unrealized losses at September 30, 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 September 30, 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 $6.5 million and below-investment-grade fixed maturity investments comprised $15.1 million of the unrealized losses on investments in fixed maturities at September 30, 2019 . For below-investment-grade fixed maturity investments in an unrealized loss position, the unrealized loss amount, on average, was approximately 6% of the amortized cost basis of the investment. At September 30, 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 it recovered the amortized cost of such investments, which may be at maturity. Based on the Company’s evaluation of the prospects of the issuers at September 30, 2019 , 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 it recovered 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. Note 3 - Investments (continued) An aging of unrealized losses on the Company’s Investments in Fixed Maturities at December 31, 2018 is presented below.

There were no unrealized losses at December 31, 2018 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, 2018 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 $69.5 million and below-investment-grade fixed maturity investments comprised $17.1 million of the unrealized losses on investments in fixed maturities at December 31, 2018 . 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, 2018 , 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, 2018 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. Note 3 - Investments (continued) The following table sets forth the pre-tax amount of other than temporary impairment (“OTTI”) credit losses recognized in Retained Earnings for Investments in Fixed Maturities held by the Company as of the beginning and end of the periods presented for which a portion of the OTTI loss related to factors other than credit has been recognized in AOCI, and the corresponding changes in such amounts.

Net unrealized gains arising during the nine months ended September 30, 2019 and recognized in earnings, related to such investments still held as of September 30, 2019 , were $98.3 million . 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 other-than-temporary 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 $0.1 million on Equity Securities at Modified Cost in other comprehensive income for the nine months ended September 30, 2019 as a result of the Company’s qualitative impairment analysis. The Company has recognized $0.2 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 September 30, 2019 . There were no unsettled sales of Investments in Equity Securities at September 30, 2019 and December 31, 2018 . There were no unsettled purchases of Investments in Equity Securities at September 30, 2019 and December 31, 2018 . 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 September 30, 2019 is limited to the total carrying value of $213.4 million . In addition, the Company had outstanding commitments totaling approximately $94.3 million to fund Equity Method Limited Liability Investments at September 30, 2019 .

Actual loss development and loss trends are likely to differ from these historical development patterns and loss trends. Loss development and loss trends emerge over several years from the dates of loss inception. The Company monitors such emerging loss development patterns on a quarterly basis. Changes in such estimates are included in the Condensed Consolidated Statements of Income in the period of change. For the nine months ended September 30, 2019 , the Company decreased its property and casualty insurance reserves by $55.8 million to recognize favorable development of loss and LAE reserves from prior accident years. Specialty Personal automobile insurance loss and LAE reserves developed favorably by $19.6 million due primarily to the emergence of more favorable loss patterns than expected for liability insurance related to the 2018 accident year. Preferred Personal automobile insurance loss and LAE reserves developed favorably by $5.6 million due primarily to the emergence of more favorable loss patterns than expected for liability insurance related to 2018 and 2017 accident years. Homeowners loss and LAE reserves developed favorably by $13.6 million primarily due to the net of reinsurance impact from the sale of subrogation rights related to the 2017 and 2018 California Wildfires. Other personal lines loss and LAE reserves developed favorably by $5.0 million due primarily to the emergence of more favorable loss patterns than expected for 2018 and 2017 accident years. Commercial automobile insurance loss and LAE reserves developed favorably by $11.1 million due primarily to the emergence of more favorable loss patterns than expected for liability insurance related to the 2018 accident year. Note 4 - Property and Casualty Insurance Reserves (continued) For the nine months ended September 30, 2018 , the Company decreased its property and casualty insurance reserves by $1.7 million to recognize favorable development of loss and LAE reserves from prior accident years. Specialty Personal automobile insurance loss and LAE reserves developed adversely by $3.1 million due primarily to the emergence of more adverse loss patterns than expected for liability insurance for the 2017 accident year. Preferred Personal automobile insurance loss and LAE reserves developed favorably by $3.6 million due primarily to the emergence of loss patterns that were better than expected for liability insurance for the 2016 and prior accident years, partially offset by the emergence of less favorable loss patterns than expected for both physical damage and liability insurance lines for the 2017 accident year. Homeowners insurance non-catastrophe loss and LAE reserves developed adversely by $10.1 million due primarily to the emergence of loss patterns that were worse than expected for the 2016 and 2015 accident years, partially offset by favorable development on catastrophes of $6.5 million related to the 2017 accident year. Other personal lines loss and LAE reserves developed favorably by $2.9 million due primarily to the emergence of more favorable loss patterns than expected for the 2016 and 2015 accident years. Commercial automobile loss and LAE reserves developed favorably by $1.4 million due primarily to the emergence of loss patterns that were more favorable than expected for the 2015 and 2014 accident year. 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.

Debt Disclosure [Abstract]
Debt	Debt Amended and Extended Credit Agreement and Term Loan Facility On June 8, 2018 , the Company entered into an amended and extended credit agreement and term loan facility. The amended and extended credit agreement increased the borrowing capacity of the existing unsecured credit agreement to $300.0 million and extended the maturity date to June 8, 2023 . The term loan facility included a delayed draw feature with borrowing capacity of $250.0 million and a maturity date two years from the borrowing date (see discussion below under heading, “Term Loan Due 2020,” for additional information). On June 4, 2019 , the Company utilized the accordion feature under the credit agreement to increase its credit borrowing capacity by $100.0 million , resulting in the available credit commitments increasing from $300.0 million to $400.0 million . The Company incurred $0.1 million in additional debt issuance costs in connection with the utilization of the accordion feature, which, in addition to the $1.1 million of remaining unamortized costs under the credit agreement, will be amortized under the remaining term of the credit agreement. There were no outstanding borrowings under the credit agreement at either September 30, 2019 or December 31, 2018 . Long-term Debt The Company designates debt obligations as either short-term or long-term based on maturity date at issuance, or in the case of the 2022 Senior Notes, based on the date of assumption. Total amortized cost of Long-term Debt outstanding at September 30, 2019 and December 31, 2018 was: (Dollars in Millions) Sep 30, Dec 31, Term Loan due June 29, 2020 $ — $ 34.9 5.0% Senior Notes due September 19, 2022 280.3 281.5 Term Loan due July 5, 2023 49.9 — 4.35% Senior Notes due February 15, 2025 448.5 448.4 7.375% Subordinated Debentures due February 27, 2054 — 144.2 Total Long-term Debt Outstanding $ 778.7 $ 909.0 Note 5 - Debt (continued) Term Loan Due 2020 On June 29, 2018 , the Company borrowed $250.0 million under its delayed-draw term loan facility, dated June 8, 2018 , to facilitate the funding of the acquisition of Infinity. The proceeds from the term loan facility, net of debt issuance costs, were $249.4 million . On December 28, 2018 , the Company repaid $215.0 million of the outstanding term loan. On May 31, 2019 , the remaining outstanding balance of $35.0 million was repaid. Term Loan Due 2023 On June 4, 2019 , the Company entered into a delayed-draw term loan facility with a borrowing capacity of $50.0 million and a maturity date four years from the borrowing date (the “2023 Term Loan”). On July 5, 2019 , the Company borrowed $49.9 million , net of debt issuance costs, under the 2023 Term Loan, with a final maturity date of July 5, 2023 (and a mutual option to extend the maturity date by one year). 5.0% Senior Notes Due 2022 Infinity’s liabilities at the acquisition date included $275.0 million principal amount, 5.0% Senior Notes due September 19, 2022 (“2022 Senior Notes”). The 2022 Senior Notes were recorded at fair value as of the acquisition date, $282.1 million , with the $7.1 million premium being amortized as a reduction to interest expense over the remaining term, resulting in an effective interest rate of 4.36% . On November 30, 2018 , Kemper executed a guarantee to fully and unconditionally guarantee the payment and performance obligations of the 2022 Senior Notes. 4.35% Senior Notes Due 2025 Kemper has $450.0 million aggregate principal of 4.35% senior notes due February 15, 2025 (the “2025 Senior Notes”) outstanding as of September 30, 2019 . Kemper initially issued $250.0 million of the notes in February of 2015 and issued an additional $200 million of the notes in June of 2017 . The additional notes are fungible with the initial notes issued in 2015, and together are treated as part of a single series for all purposes under the indenture governing the 2025 Senior Notes. The 2025 Senior Notes are unsecured and may be redeemed in whole at any time or in part from time to time at Kemper’s option at specified redemption prices. Redemption of 7.375% Subordinated Debentures Due 2054 On June 7, 2019, Kemper issued a notice of redemption for the entire $150.0 million aggregate principal outstanding of its 7.375% Subordinated Debentures due 2054 (the “ 7.375% Subordinated Debentures”) at a redemption price equal to 100% of their principal, plus accrued and unpaid interest on the redemption date. On July 8, 2019 , Kemper completed the redemption, and the 7.375% Subordinated Debentures were repaid in full. The Company recognized a loss on early extinguishment of debt of $5.8 million in its September 30, 2019 Condensed Consolidated Statement of Income. The Company used the proceeds received from Kemper’s common stock offering on June 7, 2019 , as well as a portion of the proceeds from its July 5, 2019 borrowing under the 2023 Term Loan, to repay the 7.375% Subordinated Debentures. See Note 9, “Stockholders’ Equity,” for additional information regarding the common stock offering. Collateralized Investment Borrowings Kemper’s subsidiaries, United Insurance Company of America (“United Insurance”) and Trinity Universal Insurance Company (“Trinity”), are members of the Federal Home Loan Bank (“FHLB”) of Chicago and Dallas, respectively. As a requirement of membership in the FHLB, United Insurance and Trinity maintain a certain level of investment in FHLB common stock and additional amounts based on the level of outstanding borrowings. The Company’s investments in FHLB common stock are reported at cost and included in Equity Securities at Modified Cost. The carrying value of FHLB of Chicago common stock held by United Insurance was $2.8 million and $0.8 million at September 30, 2019 and December 31, 2018 , respectively. The carrying value of FHLB of Dallas common stock held by Trinity was $3.3 million at both September 30, 2019 and December 31, 2018 . The Company periodically uses short-term and long-term FHLB borrowings for a combination of cash management, risk management, and spread investing purposes. Note 5 - Debt (continued) In March of 2018, United Insurance received advances of $10.0 million from the FHLB of Chicago.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders’ Equity Employee Stock Purchase Plan During the second quarter of 2019 , the Company’s stockholders approved the adoption of the Kemper Employee Stock Purchase Plan (“ESPP”) and the reservation of 1,300,000 shares for issuance under the ESPP. The purpose of the ESPP is to provide eligible employees of the Company and its subsidiaries with the opportunity to purchase shares of common stock at a discounted price through payroll deductions with the goal of enhancing employees’ sense of participation in the Company and further align employee interests with those of the Company’s shareholders. Under the ESPP, eligible employees may purchase shares of Company common stock through payroll deductions of between 1% and 10% of after-tax compensation each pay period, with a maximum participation of $25,000 annually. The shares are purchased at the end of each three-month offering period at a 15% discount from the closing market price as reported on the New York Stock Exchange on the last trading day of the offering period. The first offering period began on July 1, 2019 and ended on September 30, 2019. The Company issued 12,638 shares under the plan on September 30, 2019 at a discounted price of $66.26 per share. Compensation costs charged against income was $0.1 million for the three months ended September 30, 2019 . There was no tax benefit recognized by the Company in relation to the ESPP for the three months ended September 30, 2019 . Note 9 - Stockholders’ Equity (continued) Common Stock Issuance On June 7, 2019 , the Company completed a public offering of its common stock and issued 1,552,500 shares of common stock, at $83.00 per share.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The statute of limitations related to Kemper and its eligible subsidiaries’ consolidated Federal income tax returns is closed for all tax years up to and including 2011. As a result of the Company filing amended federal income tax returns resulting from an election to update interest rates used to compute the tax basis of reserves on life insurance contracts issued prior to 2018 , tax years 2012 and 2013 are under limited examination with respect to carryback adjustments associated with the amended returns. The statute of limitations related to tax years 2014 and 2015 has been extended to June 30, 2020. The expiration of the statute of limitations related to the various state income tax returns that Kemper and its subsidiaries file varies by state. There were no unrecognized tax benefits at September 30, 2019 . Liabilities for Unrecognized Tax Benefits at December 31, 2018 included $3.7 million for tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Because of the impact of deferred income tax accounting, other than for interest and penalties, the disallowance of the shorter deductibility period would not affect the effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense. Liabilities for Unrecognized Tax Benefits included accrued interest of $0.7 million at December 31, 2018 . Income taxes paid, net of refunds received, were $52.2 million for the nine months ended September 30, 2019 . Income taxes paid, net of refunds received, were $10.2 million for the nine months ended September 30, 2018 .

The valuation of assets measured at fair value in the Company’s Consolidated Balance Sheet at December 31, 2018 is summarized below. Fair Value Measurements (Dollars in Millions) Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Measured at Net Asset Value Total Fair Value Fixed Maturities: U.S. Government and Government Agencies and Authorities $ 156.5 $ 709.2 $ — $ — $ 865.7 States and Political Subdivisions — 1,619.1 — — 1,619.1 Foreign Governments — 5.9 — — 5.9 Corporate Securities: Bonds and Notes — 3,011.2 382.6 — 3,393.8 Collateralized Loan Obligations — 19.1 504.9 — 524.0 Other Mortgage- and Asset-backed — 5.8 9.9 — 15.7 Total Investments in Fixed Maturities 156.5 5,370.3 897.4 — 6,424.2 Equity Securities at Fair Value: Preferred Stocks: Finance, Insurance and Real Estate — 41.2 — — 41.2 Other Industries — 13.0 — — 13.0 Common Stocks: Finance, Insurance and Real Estate 10.2 — — — 10.2 Other Industries 0.2 0.5 — — 0.7 Other Equity Interests: Exchange Traded Funds 427.3 — — — 427.3 Limited Liability Companies and Limited Partnerships — — — 192.0 192.0 Total Investments in Equity Securities at Fair Value 437.7 54.7 — 192.0 684.4 Convertible Securities at Fair Value — 31.5 — — 31.5 Total $ 594.2 $ 5,456.5 $ 897.4 $ 192.0 $ 7,140.1 Note 13 - Fair Value Measurements (continued) The Company’s investments in Fixed Maturities that are classified as Level 1 in the two preceding tables primarily consist of U.S. Treasury Bonds and Notes. 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 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 Company’s Investments in Fixed Maturities that are classified as Level 3 in the two preceding tables are priced primarily using a market yield approach and primarily consist of collateralized loan obligations that are rated by a Nationally Recognized Statistical Rating Organization (“NRSRO”) and privately placed securities that are not rated by a NRSRO. A market yield approach uses a risk-free rate plus a credit spread depending on the underlying credit profile of the security. The Company uses a leading, nationally recognized provider of market data and analytics to price the vast majority of its collateralized loan obligations. Some of the significant inputs used by such provider are unobservable. Accordingly, the Company classifies these investments as Level 3. For floating rate securities, the risk-free rate used in the market yield is the contractual floating rate of the security. For each other individual security, the Company or the Company’s third party appraiser gathers information from market sources, relevant credit information, perceived market movements and sector news and determines an appropriate market yield for each security. The market yield selected is then used to discount the estimated future cash flows of the security to determine the fair value. The Company separately evaluates market yields based upon asset class to assess the reasonableness of the recorded fair value. For non-investment-grade Investments in Fixed Maturities that are classified as Level 3, the two primary asset classes are senior debt and junior debt. Senior debt includes those securities that receive first priority in a liquidation and junior debt includes any fixed maturity security with other than first priority in a liquidation. Note 13 - Fair Value Measurements (continued) The table below presents quantitative information about the significant unobservable inputs utilized by the Company in determining fair values for fixed maturity investments in corporate securities classified as Level 3 at September 30, 2019 .

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.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies In the ordinary course of its businesses, the Company is involved in legal proceedings, including lawsuits, arbitrations, regulatory examinations, audits and inquiries. 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 October 2015, Kemper’s subsidiary, Kemper Corporate Services, Inc. (“KCSI”), filed a demand for arbitration with the American Arbitration Association (“AAA”), claiming that Computer Sciences Corporation (“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. CSC denied KCSI’s claims and filed a counterclaim. On April 1, 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 (“DXC”). DXC stock is publicly traded on the New York Stock Exchange. In April 2017, the parties participated in an evidentiary hearing in Texas before a AAA-appointed arbitrator. Subsequently, in October 2017, the arbitrator issued a Partial Final Award finding that CSC had breached the Agreements and awarding KCSI direct damages plus pre-judgment interest. KCSI then submitted to the arbitrator a supplemental petition providing pre-judgment interest calculations and seeking an award for certain costs and expenses. In November 2017, the arbitrator issued a Note 14 - Contingencies (continued) 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 . KCSI pursued confirmation and enforcement of the Final Award in U.S. District Court in Texas. In December 2017, CSC filed a Petition to Vacate an Arbitration Award in the U.S. District Court in New York and a motion to stay the proceedings in Texas. Following briefing and a hearing, the New York district court denied CSC’s motion to stay the Texas action and instead stayed the New York action. In March 2018, the Texas district court denied CSC’s motion to transfer venue and the New York district court subsequently transferred the vacatur proceeding to Texas. In April 2018, the Texas district court consolidated the two actions and the parties briefed KCSI’s Amended Motion to Confirm Arbitration Award and CSC’s motion to vacate the arbitration award. 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 is appealing the district court’s ruling to the U.S. Court of Appeals for the Fifth Circuit. CSC has, in the meantime, 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 Statement of Income for the year ended December 31, 2018 and in its Condensed Consolidated Statement of Income for the nine months ended September 30, 2019 . The Company cannot make any assurance as to the additional amounts of the final judgment that will actually be collected or when they may be received. The unpaid balance of the final judgment is treated as a gain contingency for accounting purposes and accordingly, is not recognized in these Condensed Consolidated Financial Statements.
