Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Note 1 - 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 (“Kemper”) and its subsidiaries (individually and collectively referred to herein as the “Company”) and are unaudited. All significant intercompany accounts and transactions have been eliminated. On April 30, 2015 , Kemper acquired 100% of the outstanding common stock of Alliance United Group and its wholly-owned subsidiaries, Alliance United Insurance Company and Alliance United Insurance Services (individually and collectively referred to herein as “Alliance United”) in a cash transaction. The results of Alliance United are included in the Condensed Consolidated Financial Statements from the date of acquisition and are reported in the Company’s Property & Casualty Insurance segment. Effective January 1, 2016, the Company changed its method for estimating the interest and service cost components of expense recognized for its pension and other postretirement employee benefit plans. As a result, the Company elected to use a full yield curve approach to estimate these components of benefit cost by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. Prior to 2016, the interest and service cost components were estimated using a single weighted-average discount rate derived from the yield curve used to measure the projected benefit obligation or accumulated postretirement benefit obligation, as relevant, at the beginning of the period. The change provides a more precise measurement of interest and service costs by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates. The Company has accounted for this change as a change in accounting estimate that is inseparable from a change in accounting principle and, accordingly, recognized the effect prospectively in 2016. The change in method for estimating the interest and service cost components decreased pension expense for the nine months ended September 30, 2016 by approximately $2.7 million , but had no impact on the measurement of benefit obligations. Insurance Reserves for life insurance products are comprised of reserves for future policy benefits plus an estimate of the Company’s liability for unpaid life insurance claims and claims adjustment expenses, which includes an estimate for incurred but not reported (“IBNR”) life insurance claims. Prior to the third quarter of 2016, except when required by applicable law, the Company did not utilize the database of reported deaths maintained by the Social Security Administration or any other comparable database (a “Death Master File” or “DMF”) in its operations, including to determine its IBNR liability for life insurance products. Instead of using such a database, the Company calculated its IBNR liability for life insurance products using Company-specific historical information, which included analyzing average paid claims and the average lag between date of death and the date reported to the Company for claims for which due proof of death had been provided. In the third quarter of 2016, the Company initiated a voluntary enhancement of its claims handling procedures for its life insurance policies. The Company is now utilizing a DMF to identify potential situations where the Company has yet to be notified of an insured’s death and, as appropriate, initiating an outreach process to identify and contact beneficiaries and settle claims. Policyholders’ Benefits and Incurred Losses and Loss Adjustment Expenses for both the nine and three months ended September 30, 2016 include a pre-tax charge of $77.8 million to recognize the impact of using a DMF in the Company’s operations, including to determine its IBNR liability for unpaid claims and claims adjustment expenses for life insurance products. 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 2015 Annual Report. Adoption of New Accounting Guidance In February 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The amendments in ASU 2015-02 affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. Specifically, the amendments modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities while also eliminating the Note 1 - Basis of Presentation (continued) presumption that a general partner should consolidate a limited partnership. ASU 2015-02 may also affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. The Company's adoption and initial application as of January 1, 2016 resulted in no changes to the legal entities that the Company consolidates. In May 2015, the FASB issued ASU 2015-07 Fair Value Measurement (Topic 820), Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). ASU 2015-07 removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The amendments also remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. The Company adopted ASU 2015-07 in the first quarter of 2016 and applied its provisions on a retrospective basis. Except for the change in disclosure requirements, adoption of ASU 2015-07 did not impact the Company’s financial statements. The presentation of certain prior year amounts and disclosures have been reclassified to conform to the presentation for the current year. In May 2015, the FASB issued ASU 2015-09, Financial Services—Insurance (Topic 944): Disclosures about Short-Duration Contracts . ASU 2015-09 requires insurers to provide additional disclosures about short-duration insurance contracts, focusing particularly on the liability for unpaid claims and claim adjustment expenses. Insurers will be required to disclose tables showing incurred and paid claims development information by accident year for the number of years that claims typically remain outstanding, although not to exceed ten years, as well as a reconciliation of this information to the balance sheet. Additional disclosures will also be required on the total of IBNR liabilities plus expected development on reported claims, reserving methodologies, quantitative information about claim frequency, qualitative description of the methodologies used for determining claim frequency and average annual percentage payout of incurred claims by age. ASU 2015-09 is effective for annual periods beginning after December 31, 2015 and interim periods within annual periods beginning after December 15, 2016. Except for the additional disclosure requirements, adoption of ASU 2015-09 will not impact the Company’s financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Most significantly, ASU 2016-01 requires companies to measure equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily-determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. ASU 2016-01 also simplifies the impairment assessment of equity investments without readily-determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company currently records its Investments in Equity Securities at fair value with net unrealized appreciation or depreciation reported in Accumulated Other Comprehensive Income (“AOCI”) in Shareholders’ Equity. The Company’s Investments in Equity Securities include securities with readily-determinable fair values and securities without readily-determinable fair values. Until the Company adopts ASU 2016-01 and makes its elections for Investments in Equity Securities that do not have readily-determinable fair values, it cannot determine the impact of the adoption on its consolidated balance sheet. Subsequent to adoption, ASU 2016-01 is expected to cause increased volatility in the Company’s Consolidated Statements of Operations. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842 ), by amending the Accounting Standards Codification and creating a new topic on accounting for leases. ASU 2016-02 introduces a lessee model that requires most leases to be reported on the balance sheet of a lessee. ASU 2016-02 also aligns many of the underlying principles of the new lessor model with those in ASC 606, the FASB’s new revenue recognition standard (e.g., those related to evaluating when profit can be recognized). Furthermore, ASU 2016-02 addresses other concerns related to the current leases model. For example, ASU 2016-02 eliminates the requirement in current GAAP for an entity to use bright-line tests in determining lease classification. ASU 2016-02 also requires lessors to increase the transparency of their exposure to changes in value of their residual assets and how they manage that exposure. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 and interim Note 1 - Basis of Presentation (continued) periods within those years with early adoption permitted. The Company is currently evaluating the impact of this guidance on its financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718) , which simplifies several aspects of the accounting for share-based payment transactions, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods with early adoption permitted. The Company does not anticipate adoption to have a material impact on its financial statements. 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 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 on the financial asset. 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 the ASU 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. The Company has adopted all other recently issued accounting pronouncements with effective dates prior to October 1, 2016. There were no adoptions of such accounting pronouncements in 2015 or during the nine months ended September 30, 2016 that had a material impact on the Company’s Condensed Consolidated Financial Statements. With the possible exceptions of ASU 2015-09, Financial Services—Insurance (Topic 944): Disclosures about Short-Duration Contracts, ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , ASU 2016-02, Leases (Topic 842 ) and ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, the Company does not expect the adoption of all other recently issued accounting pronouncements with effective dates after September 30, 2016 to have a material impact on the Company’s financial statements and/or disclosures.

The portions of the declines in the fair values of investments that are determined to be other than temporary are reported as losses in the Condensed Consolidated Statements of Operations in the periods when such determinations are made. Unrealized losses on fixed maturities, which the Company has determined to be temporary at September 30, 2016 , were $15.4 million , of which $8.2 million was related to fixed maturities that were in an unrealized loss position for 12 months or longer. There were no unrealized losses at September 30, 2016 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, 2016 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 $2.1 million , and below-investment-grade fixed maturity investments comprised $13.3 million of the unrealized losses on investments in fixed maturities at September 30, 2016 . 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 September 30, 2016 , 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 at September 30, 2016 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 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 2 - Investments (continued) For equity securities, the Company considers various factors when determining whether a decline in the fair value is other than temporary, including, but not limited to: • The financial condition and prospects of the issuer; • The length of time and magnitude of the unrealized loss; • The volatility of the investment; • Analysts’ recommendations and near-term price targets; • Opinions of the Company’s external investment managers; • Market liquidity; • Debt-like characteristics of perpetual preferred stocks and issuer ratings; and • The Company’s intention to sell or ability to hold an investment until recovery. With respect to Investments in Equity Securities, the Company concluded that the unrealized losses on its investments in preferred and common stocks at September 30, 2016 were temporary based on various factors, including the relative short length and magnitude of the losses and overall market volatility. The Company’s investments in other equity interests include investments in limited liability companies and limited partnerships that primarily invest in mezzanine debt, distressed debt and secondary transactions. By the nature of their underlying investments, the Company believes that some of its investments in the limited liability companies and limited partnerships exhibit debt-like characteristics which, among other factors, the Company also considers when evaluating these investments for impairment. Based on evaluations of the factors in the preceding paragraph, the Company concluded that the declines in the fair values of the Company’s investments in equity securities presented in the preceding table were temporary at September 30, 2016 .

There were $0.2 million unrealized losses at December 31, 2015 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, 2015 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 $33.5 million and below-investment-grade fixed maturity investments comprised $16.5 million of the unrealized losses on investments in fixed maturities at December 31, 2015 . For below-investment-grade fixed maturity investments in an unrealized loss position, the unrealized loss amount, on average, was approximately 8% of the amortized cost basis of the investment. At December 31, 2015 , 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, 2015 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. With respect to Investments in Equity Securities, the Company concluded that the unrealized losses on its investments at December 31, 2015 were temporary based on various factors, including the relative short length and magnitude of the losses and overall market volatility, as well as, the debt-like characteristics of investments in certain other equity interests. Note 2 - 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.

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 Operations in the period of change. For the nine months ended September 30, 2016 , the Company reduced its property and casualty insurance reserves by $21.0 million to recognize favorable development of loss and LAE reserves from prior accident years. Personal lines insurance loss and LAE reserves developed favorably by $17.7 million , and commercial lines insurance loss and LAE reserves developed favorably by $3.3 million . The commercial lines insurance loss and LAE reserve development included no development from continuing operations and favorable development of $3.3 million from discontinued operations. Personal automobile insurance loss and LAE reserves developed adversely by $7.3 million due primarily to the emergence of loss patterns that were worse than expected for liability insurance for the 2015 accident year. Homeowners insurance loss and LAE reserves developed favorably by $18.1 million due primarily to $14.3 million of favorable development on catastrophes primarily for the 2015 and 2014 accident years. Other personal lines loss and LAE reserves developed favorably by $6.9 million due primarily to the emergence of more favorable loss patterns than expected for the 2015, 2014, 2013 and 2012 accident years. Note 3 - Property and Casualty Insurance Reserves (continued) For the nine months ended September 30, 2015 , the Company reduced its property and casualty insurance reserves by $16.3 million to recognize favorable development of loss and LAE reserves from prior accident years. Personal lines insurance loss and LAE reserves developed favorably by $13.5 million , and commercial lines insurance loss and LAE reserves developed favorably by $2.8 million . The commercial lines insurance loss and LAE reserve development included adverse development of $0.7 million from continuing operations and favorable development of $3.5 million from discontinued operations. Personal automobile insurance loss and LAE reserves developed favorably by $5.6 million , homeowners insurance loss and LAE reserves developed favorably by $8.8 million , and other personal lines loss and LAE reserves developed adversely by $0.9 million . Personal lines insurance loss and LAE reserves developed favorably due primarily to the emergence of more favorable loss patterns than expected for the 2013, 2012 and 2011 accident years, partially offset by the emergence of loss patterns that were worse than expected for the 2014 accident year. The Company cannot predict whether loss and LAE reserves will develop favorably or unfavorably 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.

Income (Loss) from Continuing Operations Per Unrestricted Share	Note 5 - Income (Loss) from Continuing Operations Per Unrestricted Share The Company’s awards of restricted stock contain rights to receive non-forfeitable dividends and participate in the undistributed earnings with common shareholders. The Company’s awards of restricted stock units and deferred stock units also contain rights to receive non-forfeitable dividend equivalents and participate in the undistributed earnings with common shareholders. Accordingly, the Company is required to apply the two-class method of computing basic and diluted earnings per share. A reconciliation of the numerator and denominator used in the calculation of Basic Income (Loss) from Continuing Operations Per Unrestricted Share and Diluted Income (Loss) from Continuing Operations Per Unrestricted Share for the nine and three months ended September 30, 2016 and 2015 is presented below.

The expiration of the statute of limitations related to the various state income tax returns that Kemper and its subsidiaries file varies by state. Included in the balance of Unrecognized Tax Benefits at September 30, 2016 and December 31, 2015 are tax positions of $3.2 million and $3.3 million , respectively, 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. The liability for Unrecognized Tax Benefits included accrued interest of $0.5 million and $0.5 million at September 30, 2016 and December 31, 2015 , respectively. Income taxes paid were $10.4 million and $40.1 million for the nine months ended September 30, 2016 and 2015 , respectively.

Compensation and Retirement Disclosure [Abstract]
Pension Benefits and Postretirement Benefits Other Than Pensions	Note 9 - Pension Benefits and Postretirement Benefits Other Than Pensions The Company sponsors a qualified defined benefit pension plan (the “Pension Plan”). The Pension Plan covers approximately 9,200 participants and beneficiaries, of which 1,800 are active employees. The Pension Plan is closed to new employees hired after January 1, 2006. The components of Pension Expense (Benefit) for the Pension Plan for the nine and three months ended September 30, 2016 and 2015 were: Nine Months Ended Three Months Ended (Dollars in Millions) Sep 30, Sep 30, Sep 30, Sep 30, Service Cost Earned $ 4.8 $ 7.9 $ — $ 2.7 Interest Cost on Projected Benefit Obligation 15.2 19.3 4.8 6.5 Expected Return on Plan Assets (24.5 ) (26.3 ) (8.3 ) (8.8 ) Amortization of Accumulated Net Unrecognized Pension Costs 5.8 18.3 0.9 6.1 Curtailment Gain (0.3 ) — — — Total Pension Expense (Benefit) Recognized $ 1.0 $ 19.2 $ (2.6 ) $ 6.5 On May 12, 2016, the Company amended the Pension Plan to freeze benefit accruals, effective June 30, 2016, for substantially all of the participants under the plan. Accordingly, plan assets and liabilities were re-measured, resulting in balances in accumulated unrecognized pension loss and unamortized prior service credit prior to the freeze of $191.2 million and $0.3 million , respectively. In recognizing the curtailment, the Company recorded income of $0.3 million before income taxes in the second quarter of 2016 to immediately recognize the remaining unamortized prior service credit in the Pension Plan. The curtailment reduced the accumulated unrecognized pension loss by $23.3 million . The remaining accumulated unrecognized Note 9 - Pension Benefits and Postretirement Benefits Other Than Pensions (continued) pension loss of $167.9 million is being amortized over approximately 25 years , the remaining average estimated life expectancy of participants. Prior to the amendment, the accumulated unrecognized pension loss was being amortized over approximately five years, the remaining average service life of active participants. On August 12, 2016, the Company made a voluntary cash contribution of $9.0 million to the Pension Plan. The Company also sponsors a non-qualified supplemental defined benefit pension plan (the “Supplemental Plan”). As a result of the amendment to the Pension Plan, benefit accruals for all participants in the Supplemental Plan were also frozen effective June 30, 2016. Accordingly, plan liabilities for the Supplemental Plan were also re-measured in the second quarter of 2016, resulting in balances in accumulated unrecognized pension loss and unamortized prior service costs prior to the freeze of $1.6 million and $1.3 million , respectively. The Company recorded expense of $1.3 million in the second quarter of 2016 to immediately recognize the remaining net unamortized prior service costs in the Supplemental Plan. The curtailment reduced the Projected Benefit Obligation by $5.2 million . Accordingly, a curtailment gain of $3.6 million before tax was recorded to recognize the reduction in the Projected Benefit Obligation that exceeded the accumulated unrecognized pension loss prior to the freeze. In addition to the Pension Plan and Supplemental Plan, the Company also sponsors several defined contribution benefit plans. The Company also sponsors an other postretirement benefit (“OPEB”) plan that provides medical, dental and/or life insurance benefits to approximately 500 retired and 225 active employees (the “OPEB Plan”). The components of OPEB Benefit for the OPEB Plan for the nine and three months ended September 30, 2016 and 2015 were: Nine Months Ended Three Months Ended (Dollars in Millions) Sep 30, Sep 30, Sep 30, Sep 30, Service Cost Earned $ 0.1 $ 0.1 $ 0.1 $ — Interest Cost on Accumulated Postretirement Benefit Obligation 0.6 0.8 0.2 0.3 Amortization of Accumulated Net Unrecognized Gain (1.1 ) (1.1 ) (0.4 ) (0.4 ) Total OPEB Benefit $ (0.4 ) $ (0.2 ) $ (0.1 ) $ (0.1 )

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 11 - Fair Value Measurements The Company classifies its investments in Fixed Maturities and Equity Securities as available for sale and reports these investments at fair value. The Company has elected the fair value option method of accounting for investments in certain hedge funds and, accordingly, reports these investments at fair value. The Company classifies certain investments in mutual funds included in Other Investments as trading securities and reports these investments at fair value. The Company has no material liabilities that are measured and reported at fair value. Certain investments that are measured at fair value using the net asset value practical expedient are not required to be classified using the fair value hierarchy, but are presented in the following two tables to permit reconciliation of the fair value hierarchy to the amounts presented in the Condensed Consolidated Balance Sheet. The valuation of assets measured at fair value in the Company’s Condensed Consolidated Balance Sheet at September 30, 2016 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 $ 129.4 $ 180.9 $ — $ — $ 310.3 States and Political Subdivisions — 1,658.5 4.1 — 1,662.6 Foreign Governments — 3.6 — — 3.6 Corporate Securities: Bonds and Notes — 2,627.3 442.0 — 3,069.3 Redeemable Preferred Stocks — — 0.9 — 0.9 Collateralized Loan Obligations — 10.1 111.3 — 121.4 Other Mortgage- and Asset-backed — 2.0 — — 2.0 Total Investments in Fixed Maturities 129.4 4,482.4 558.3 — 5,170.1 Equity Securities: Preferred Stocks: Finance, Insurance and Real Estate — 77.7 5.3 — 83.0 Other Industries — 11.8 13.7 — 25.5 Common Stocks: Finance, Insurance and Real Estate 15.7 8.6 — — 24.3 Other Industries 0.3 0.5 12.0 — 12.8 Other Equity Interests: Exchange Traded Funds 151.3 — — — 151.3 Limited Liability Companies and Limited Partnerships — — 39.0 169.0 208.0 Total Investments in Equity Securities 167.3 98.6 70.0 169.0 504.9 Fair Value Option Investments: Limited Liability Companies and Limited Partnerships Hedge Funds — — — 126.1 126.1 Other Investments: Trading Securities 5.2 — — — 5.2 Total $ 301.9 $ 4,581.0 $ 628.3 $ 295.1 $ 5,806.3 At September 30, 2016 , the Company had unfunded commitments to invest an additional $126.0 million in certain limited liability investment companies and limited partnerships that will be included in Other Equity Interests when funded. Note 11 - Fair Value Measurements (continued) The valuation of assets measured at fair value in the Company’s Condensed Consolidated Balance Sheet at December 31, 2015 is summarized below.

The Company’s investments in Equity Securities 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 that are classified as Level 2 in the two preceding tables primarily Note 11 - Fair Value Measurements (continued) 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 primarily consist of privately placed securities not rated by a Nationally Recognized Statistical Rating Organization and are priced primarily using a market yield approach. A market yield approach uses a risk-free rate plus a credit spread depending on the underlying credit profile of the security. For floating rate securities, the risk-free rate used in the market yield is the contractual floating rate of the security. For each 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. 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, 2016 . (Dollars in Millions) Unobservable Input Total Fair Value Range of Unobservable Inputs Weighted-average Yield Investment-grade Market Yield $ 102.1 2.4 % - 4.7 % 3.2 % Non-investment-grade: Senior Debt Market Yield 145.1 4.3 - 19.3 10.2 Junior Debt Market Yield 184.9 8.8 - 26.0 13.3 Collateralized Loan Obligations Market Yield 111.3 3.6 - 9.6 6.3 Other Various 10.8 Total Level 3 Fixed Maturity Investments in Corporate Securities $ 554.2 Note 11 - 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 December 31, 2015 .

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. The Company’s other investments that are classified as Level 3 primarily consist of Limited Liability Companies and Limited Partnerships, but also certain Preferred Stocks and Common Stocks. The Company either uses valuations provided by third party fund managers or third party appraisers, or that are generated internally. These valuations typically employ various valuation techniques commonly used in the industry, including earnings multiples based on comparable public securities, industry-specific non-earnings based multiples, market yields based on comparable public securities and discounted cash flow models.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Note 12 - Contingencies In the ordinary course of its businesses, the Company is involved in legal proceedings, including lawsuits, 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 several years there have been an array of initiatives that seek, in various ways, to impose new duties on life insurance companies to proactively search for deaths of their insureds. These initiatives, which can include legislation, unclaimed property audits, market conduct examinations and related litigation, could have the effect of altering the terms of Kemper’s life insurance subsidiaries’ existing life insurance contracts by imposing requirements that did not exist and were not contemplated at the time those companies entered into such contracts. In the third quarter of 2016, the Company voluntarily began implementing a comprehensive process to compare life insurance records against one or more death verification databases to determine if any of its insureds may be deceased. See Note 1, “Basis of Presentation,” to the Condensed Consolidated Financial Statements for discussion of the estimated financial impact of such voluntary action recognized in the Company’s Condensed Consolidated Financial Statements. Any attempt to estimate the ultimate outcomes of the aforementioned initiatives entails uncertainties including, but not limited to (i) the scope and interpretation of DMF statutes, including the matching criteria and methodologies to be used in comparing policy records against a DMF, (ii) the universe of policies affected, (iii) the results of audits, examinations and other actions by regulators and (iv) related litigation.
