Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Estimates	NOTE 1. BASIS OF PRESENTATION AND SIGNIFICANT ESTIMATES The Consolidated Financial Statements included herein have been prepared on the basis of accounting principles generally accepted in the United States (“GAAP”) and include the accounts of Kemper Corporation (“Kemper”) and its subsidiaries (individually and collectively referred to herein as the “Company”). All significant intercompany accounts and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates and assumptions. The fair values of the Company’s Investments in Fixed Maturities, Investments in Equity Securities, Fair Value Option Investments, Short-term Investments, Trading Securities, derivative instrument included in Other Assets and Debt are estimated using a hierarchical framework which prioritizes and ranks market price observability. The carrying amounts reported in the Consolidated Balance Sheets approximate fair value for Cash, Short-term Investments and certain other assets and other liabilities because of their short-term nature. The actual value at which financial instruments could be sold or settled with a willing buyer or seller may differ from estimated fair values depending on a number of factors, including, but not limited to, current and future economic conditions, the quantity sold or settled, the presence of an active market and the availability of a willing buyer or seller. The process of estimating and establishing reserves for losses and loss adjustment expenses ("LAE") for property and casualty insurance is inherently uncertain, and the actual ultimate net cost of known and unknown claims may vary materially from the estimated amounts reserved. The reserving process is particularly imprecise for claims involving long-tailed exposures, which may not be discovered or reported until years after the insurance policy period has ended. Management considers a variety of factors, including, but not limited to, past claims experience, current claim trends and relevant legal, economic and social conditions, in estimating reserves. A change in any one or more factors is likely to result in the ultimate net claim costs to differ from the estimated reserve. Changes in such estimates may be material and would be recognized in the Consolidated Financial Statements when such estimates change. The process of determining whether an asset is impaired or recoverable relies on projections of future cash flows, operating results and market conditions. Projections are inherently uncertain, and, accordingly, actual future cash flows may differ materially from projected cash flows. As a result, the Company’s assessment of the impairment of long-lived assets is susceptible to the risk inherent in making such projections.

Accounting Policies [Abstract]
Summary Of Accounting Policies And Accounting Changes	NOTE 2. SUMMARY OF ACCOUNTING POLICIES AND ACCOUNTING CHANGES Investments Investments in Fixed Maturities include bonds, notes and redeemable preferred stocks. Investments in Fixed Maturities are classified as available for sale and reported at fair value. Net Investment Income, including amortization of purchased premiums and accretion of market discounts, on Investments in Fixed Maturities is recognized as interest over the period that it is earned using the effective yield method. Investments in Equity Securities include common and non-redeemable preferred stocks and other equity interests and are reported at fair value. Investments in common and non-redeemable preferred stocks with readily determinable fair values are classified as available for sale. Dividend income on investments in common and non-redeemable preferred stocks is recognized on the ex-dividend date. Other equity interests primarily consist of exchange traded funds and interests in limited liability companies and limited partnerships in which the Company’s interests are deemed minor. The Company’s share of distributed earnings from other equity interests is recognized as dividend income when received. Unrealized appreciation or depreciation, net of applicable deferred income taxes, on fixed maturities and equity securities classified as available for sale is reported in Accumulated Other Comprehensive Income (“AOCI”) included in Shareholders’ Equity. 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. NOTE 2. SUMMARY OF ACCOUNTING POLICIES AND ACCOUNTING CHANGES (Continued) Fair Value Option Investments include investments in certain hedge funds, which the Company has elected the fair value option (“FVO”) to account for such investments. Under the FVO method of accounting, the Company reports changes in the fair value of such investments in Net Investment Income in the Consolidated Statements of Income. The hedge funds are designed to preserve liquidity, while providing higher returns than Kemper would otherwise expect to earn had it invested in other short-term investments. Short-term Investments include certificates of deposits and other fixed maturities that mature within one year from the date of purchase, U.S. Treasury bills, money market mutual funds, overnight interest bearing accounts, and repurchase agreements. Short-term Investments are reported at cost, which approximates fair value. Other Investments primarily include loans to policyholders and real estate. Loans to policyholders are carried at unpaid principal balance. Real estate is carried at cost, net of accumulated depreciation. Real estate is depreciated over the estimated useful life of the asset using the straight-line method of depreciation. Real estate is evaluated for impairment when events or circumstances indicate the carrying value may not be recoverable. An impairment loss on real estate is recognized when the carrying value exceeds the sum of undiscounted projected future cash flows as well as the fair value, or, in the case of a property classified as held for sale, when the carrying value exceeds the fair value, net of costs to sell. Gains and losses on sales of investments are computed on the specific identification method and are reported in the Consolidated Statements of Income in the period in which the sales occur. The Company regularly reviews its investment portfolio for factors that may indicate that a decline in fair value of an investment is other than temporary. Losses are computed on the specific identification method and reported in the Consolidated Statements of Income in the period that the decline is determined to be other than temporary. The portion of an impairment of an investment in a fixed maturity attributed to a credit loss is reported in Net Impairment Losses Recognized in Earnings in the Consolidated Statements of Income, with the portion of the impairment that is not attributed to a credit loss reported in AOCI. Fair Value Measurements The Company uses a hierarchical framework which prioritizes and ranks the market observability of inputs used in fair value measurements. Market price observability is affected by a number of factors, including the type of asset or liability and the characteristics specific to the asset or liability being measured. Assets and liabilities with readily available, active, quoted market prices or for which fair value can be measured from actively quoted prices generally are deemed to have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. The Company classifies the inputs used to measure fair value into one of three levels as follows: • Level 1 — Quoted prices in an active market for identical assets or liabilities; • Level 2 — Observable inputs other than Level 1, quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, and model-derived prices whose inputs are observable or whose significant value drivers are observable; and • Level 3 — Unobservable inputs for the asset or liability being measured. Observable inputs are based on market data obtained from independent sources, while unobservable inputs are based on the Company’s market assumptions. Unobservable inputs require significant management judgment or estimation. In some cases, the inputs used to measure an asset or liability may fall into different levels of the fair value hierarchy. In those cases, the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level of input that is significant to the entire measurement. Such determination requires significant management judgment. However, in accordance with GAAP, the Company is not permitted to use management judgment to adjust quoted market prices in an active market. Deferred Policy Acquisition Costs Costs directly associated with the successful acquisition of business, principally commissions and certain premium taxes and policy issuance costs, are deferred. Costs deferred on property and casualty insurance contracts and short duration health insurance contracts are amortized over the period in which premiums are earned. Costs deferred on traditional life insurance products and other long-duration insurance contracts are primarily amortized over the anticipated premium-paying period of the related policies in proportion to the ratio of the annual premiums to the total premiums anticipated, which is estimated using the same assumptions used in calculating policy reserves. NOTE 2. SUMMARY OF ACCOUNTING POLICIES AND ACCOUNTING CHANGES (Continued) Goodwill The cost of an acquired entity over the fair value of net assets acquired is reported as Goodwill. Goodwill is not amortized, but rather is tested for recoverability annually or when certain triggering events require testing. Insurance Reserves Reserves for losses and LAE on property and casualty insurance coverage and health insurance coverage represent the estimated claim cost and loss adjustment expense necessary to cover the ultimate net cost of investigating and settling all losses incurred and unpaid at the end of any given accounting period. Such estimates are based on individual case estimates for reported claims and estimates for incurred but not reported (“IBNR”) losses, including expected development on reported claims. These estimates are adjusted in the aggregate for ultimate loss expectations based on historical experience patterns and current economic trends, with any change in the estimated ultimate liabilities being reported in the Consolidated Statements of Income in the period of change. Changes in such estimates may be material. For traditional life insurance products, the reserves for future policy benefits are estimated on the net level premium method using assumptions as of the issue date for mortality, interest, policy lapses and expenses, including provisions for adverse mortality. These assumptions vary by such characteristics as plan, age at issue and policy duration. Mortality assumptions are based on the Company’s historical experience and industry standards. Interest rate assumptions principally range from 3% to 7% . Lapse rate assumptions are based on actual and industry experience. 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 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 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 the year ended December 31, 2016 include a charge of $77.8 million to recognize the initial 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. Other Receivables Other Receivables primarily include reinsurance recoverables and accrued investment income. Reinsurance Recoverables were $106.4 million and $108.3 million at December 31, 2016 and 2015 , respectively. Accrued Investment Income was $70.8 million and $68.5 million at December 31, 2016 and 2015 , respectively. Other Assets Other Assets primarily include property and equipment, internal use software, insurance licenses acquired in business combinations, the value of other intangible assets acquired, corporate-owned life insurance and prepaid expenses. Property and equipment is depreciated over the useful lives of the assets, generally using the straight-line or double declining balance methods of depreciation depending on the asset involved. Internal use software is amortized over the useful life of the asset using the straight-line method of amortization. Write-offs of Long-lived Assets for the year ended December 31, 2015 was a charge of $11.1 million to write off the costs of a computer software development project that was abandoned by the Company’s Property & Casualty Insurance segment. Write-offs of Long-lived Assets for the year ended December 31, 2014 was a charge of $54.6 million to write off certain software for the Company’s Property & Casualty Insurance segment after the Company determined that it was no longer probable that the software would be fully implemented. Insurance licenses acquired in business combinations and other indefinite life intangibles are not amortized, but rather tested periodically for recoverability. NOTE 2. SUMMARY OF ACCOUNTING POLICIES AND ACCOUNTING CHANGES (Continued) Corporate-owned life insurance is reported at cash surrender value with changes due to cost of insurance and investment experience reported in Other Income in the Consolidated Statements of Income. The Company accounts for the present value of the future profits embedded in life insurance in force acquired (“Life VIF”) based on actuarial estimates of the present value of estimated net cash flows. Life VIF was $28.9 million and $32.5 million at December 31, 2016 and 2015 , respectively. Life VIF is amortized using the effective interest method using interest rates consistent with the rates in the underlying insurance contracts. The Company estimates that it will record Life VIF amortization, net of interest, of $3.1 million in 2017, $2.8 million in 2018, $2.4 million in 2019, $2.0 million in 2020 and $1.8 million in 2021. The Company evaluates the Life VIF for recoverability annually. The Company accounts for the present value of the future profits embedded in Property and Casualty Insurance Customer Relationships Acquired (“P&C Customer Relationships”) based on the present value of estimated future cash flows from the customer relationships acquired. P&C Customer Relationships was $9.0 million and $11.2 million at December 31, 2016 and 2015 , respectively. P&C Customer Relationships is amortized using the effective interest method. P&C Customer Relationships is tested for recoverability using undiscounted projections of future cash flows and written down to estimated fair value if the carrying value exceeds the sum of such projections of undiscounted cash flows. The Company accounts for the present value of the future profits embedded in Property and Casualty Insurance Broker Relationships Acquired (“P&C Broker Relationships”) based on the present value of estimated future cash flows from the broker relationships acquired. P&C Broker Relationships was $16.8 million and $18.1 million at December 31, 2016 and 2015 , respectively. P&C Broker Relationships is amortized on a straight-line basis over 15 years . P&C Broker Relationships is tested for recoverability using undiscounted projections of future cash flows and written down to estimated fair value if the carrying value exceeds the sum of such projections of undiscounted cash flows. Accrued Expenses and Other Liabilities Accrued Expenses and Other Liabilities primarily include accrued salaries and commissions, pension benefits, postretirement medical benefits and accrued taxes, licenses and fees. Recognition of Earned Premiums and Related Expenses Property and casualty insurance and short duration health insurance premiums are deferred when written and recognized and earned ratably over the periods to which the premiums relate. Unearned Premiums represent the portion of the premiums written related to the unexpired portion of policies in force which has been deferred and is reported as a liability. The Company performs a premium deficiency analysis typically at a product line level, namely automobile insurance, homeowners insurance and other insurance, which is consistent with the manner in which the Company acquires and services policies and measures profitability. Anticipated investment income is excluded from such analysis. A premium deficiency is recognized when the sum of expected claim costs, claim adjustment expenses, unamortized deferred policy acquisition costs and maintenance costs exceeds the related unearned premiums by first reducing related deferred policy acquisition costs to an amount, but not below zero, at which the premium deficiency would not exist. If a premium deficiency remains after first reducing deferred policy acquisition costs, a premium deficiency reserve is established and reported as a liability in the Company’s financial statements. The Company’s deferred policy acquisition costs in the Consolidated Balance Sheets at December 31, 2016 and 2015 include reductions of $9.7 million and $9.0 million , respectively, due to premium deficiencies with respect to Alliance United’s personal automobile book of business. Traditional life insurance premiums are recognized as revenue when due. Policyholders’ benefits are associated with related premiums to result in recognition of profits over the periods for which the benefits are provided using the net level premium method. Policyholders’ Benefits and Incurred Losses and Loss Adjustment Expenses include provisions for future policy benefits under life and certain accident and health insurance contracts and provisions for reported claims, estimates for IBNR claims and loss adjustment expenses. Benefit payments in excess of policy account balances are expensed. Reinsurance In the normal course of business, Kemper’s insurance subsidiaries reinsure certain risks above certain retention levels with other insurance enterprises. These reinsurance agreements do not relieve Kemper’s insurance subsidiaries of their legal obligations to the policyholder. Amounts recoverable from reinsurers are included in Other Receivables. NOTE 2. SUMMARY OF ACCOUNTING POLICIES AND ACCOUNTING CHANGES (Continued) Gains related to long-duration reinsurance contracts are deferred and amortized over the life of the underlying reinsured policies. Losses related to long-duration reinsurance contracts are recognized immediately. Any gain or loss associated with reinsurance agreements for which Kemper’s insurance subsidiaries have been legally relieved of their obligations to the policyholder is recognized in the period of relief. Income Taxes Deferred income tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. A valuation allowance, if any, is maintained for the portion of deferred income tax assets that the Company does not expect to recover. Increases, if any, in the valuation allowance for deferred income tax assets are recognized as income tax expense. Decreases, if any, in the valuation allowance for deferred income tax assets are recognized as income tax benefit. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in income in the period in which the change is enacted. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken, or expected to be taken, in an income tax return. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense. Change in Accounting and Adoption of New Accounting Standards 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 year ended December 31, 2016 by approximately $2.7 million , but had no impact on the measurement of benefit obligations. 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 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 NOTE 2. SUMMARY OF ACCOUNTING POLICIES AND ACCOUNTING CHANGES (Continued) particularly on the liability for unpaid claims and claim adjustment expenses. Insurers are 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 are also required on the total of IBNR liabilities, including 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 did 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 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 (“ASC”) 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 Topic 606, Revenue from Contracts with Customers, 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 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 NOTE 2. SUMMARY OF ACCOUNTING POLICIES AND ACCOUNTING CHANGES (Continued) 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 recently issued accounting pronouncements with effective dates prior to January 1, 2017. There were no adoptions of such accounting pronouncements in 2016 that had a material impact on the Company’s Consolidated Financial Statements. With the possible exceptions of 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 December 31, 2016 to have a material impact on the Company’s financial statements.

INVESTMENTS (Continued) The Company regularly reviews its investment portfolio for factors that may indicate that a decline in fair value of an investment is other than temporary. 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 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 December 31, 2016 , were $46.5 million , of which $7.8 million was related to fixed maturities that were in an unrealized loss position for 12 months or longer. There were unrealized losses of $0.1 million at December 31, 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 December 31, 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 $33.8 million and below-investment-grade fixed maturity investments comprised $12.7 million of the unrealized losses on investments in fixed maturities at December 31, 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 December 31, 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 recovery of its amortized cost basis, which may be at maturity. Based on the Company’s evaluation at December 31, 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 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. 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; • Analyst 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 intentions to sell or ability to hold the investments 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 December 31, 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 December 31, 2016 .

There were unrealized losses of $0.2 million 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 less than 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 4. INVESTMENTS (Continued) The following table sets forth the pre-tax amount of Other Than Temporary Impairments (“OTTI”) credit losses, recognized in Retained Earnings for Investments in Fixed Maturities held by the Company as of December 31, 2016 , 2015 and 2014 , 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.

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. In 2016 and 2015, aggregate investment income (losses) from Equity Method Limited Liability Investments exceeded 10% of the Company’s pretax consolidated net income. Accordingly, the Company is disclosing aggregated summarized financial data for its Equity Method Limited Liability Investments. Such aggregated summarized financial data does not represent the Company’s proportionate share of the Equity Method Limited Liability Investment assets or earnings. Aggregate total assets of the Equity Method Limited Liability Investments in which the Company invested totaled $2,618.1 million and $3,801.7 million as of December 31, 2016 and 2015 , respectively. Aggregate total liabilities of the Equity Method Limited Liability Investments in which the Company invested totaled $828.0 million and $879.1 million as of December 31, 2016 and 2015 , respectively. Aggregate net income of the Equity Method Limited Liability Investments in which the Company invested totaled $85.0 million , $159.6 million and $96.2 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. The aggregate summarized financial data is based on the most recent and sufficiently-timely financial information available to the Company as of the respective reporting dates and periods. The Company’s maximum exposure to loss at December 31, 2016 is limited to the total carrying value of $175.9 million . In addition, the Company had outstanding commitments totaling approximately $76.3 million to fund Equity Method Limited Liability Investments at December 31, 2016 .

Liability for Future Policy Benefits and Unpaid Claims and Claims Adjustment Expense [Abstract]
Property and Casualty Insurance Reserves	NOTE 6. PROPERTY AND CASUALTY INSURANCE RESERVES The Company’s Property and Casualty Insurance Reserves are reported using the Company’s estimate of its ultimate liability for losses and LAE for claims that occurred prior to the end of any given accounting period but have not yet been paid. Such estimates are based on individual case estimates for reported claims and estimates for IBNR losses, including expected development on reported claims. The determination of individual case reserves differs by line of business. For preferred personal automobile insurance, homeowners insurance and other personal insurance, case reserves are set by adjusters and are based on the adjusters’ estimates of the amount for which the claims will ultimately be paid. For non-standard personal automobile insurance and commercial automobile insurance, case reserves are set primarily using statistical reserves that are based on studies of historical average paid amounts by state, coverage and product. However, when such reserves exceed certain thresholds they are set manually by adjusters. The Company’s actuaries generally estimate ultimate losses and LAE and, therefore, reserves at least quarterly for most product lines and/or coverage levels using accident quarters spanning 10 or more years, depending on the size of the product line and/or coverage level or emerging issues relating to them. The Company’s actuaries use a variety of generally accepted actuarial loss reserving estimation methodologies to estimate the ultimate losses and LAE for the current accident quarter and re-estimate the ultimate losses and LAE for previous accident quarters to determine if changes in the previous estimates of the ultimate losses and LAE are indicated by the most recent data. The key assumption in these estimation methodologies is that patterns observed in prior periods are indicative of how losses and LAE are expected to develop in the future and that such historical data can be used to predict and estimate ultimate losses and LAE. However, changes in the Company’s business processes, by their very nature, are likely to affect the development patterns, which generally results in the historical development factors becoming less reliable over time in predicting how losses and LAE will ultimately develop. The Company’s actuaries use professional judgment in determining how much weight to place on the development patterns based on the older historical data and how much weight to place on the development patterns based on more recent data. In some cases, the Company’s actuaries make adjustments to the loss reserving estimation methodologies to estimate ultimate losses and LAE. The Company’s actuaries’ quarterly selections are summed by product and/or coverage levels to create the actuarial indication of the ultimate losses and LAE. Paid amounts are then subtracted from the ultimates to compute the reserves for property and casualty insurance losses and LAE. These results are reviewed by the Company’s corporate actuary and corporate management who apply their collective judgment and determine the appropriate estimated level of reserves to record. Numerous factors are considered in this determination process, including, but not limited to, the assessed reliability of key loss trends and assumptions that may be significantly influencing the current actuarial indications, changes in claim handling practices or other changes that affect the timing of payment or development patterns, changes in the mix of business, the maturity of the accident year, pertinent trends observed over the recent past, the level of volatility within a particular line of business, the improvement or deterioration of actuarial indications in the current period as compared to prior periods, and the amount of reserves related to third party pools for which the Company does not have access to the underlying data and, accordingly, relies on calculations provided by such pools. The Company’s goal is to ensure that its total reserves for property and casualty insurance losses and LAE are adequate to cover all costs, while sustaining minimal variation from the time reserves for losses and LAE are initially estimated until losses and NOTE 6. PROPERTY AND CASUALTY INSURANCE RESERVES (Continued) LAE are fully developed. Changes in the Company’s estimates of these losses and LAE over time, also referred to as “development,” will occur and may be material. The following tables contain information about incurred and paid claims development as of and for the year December 31, 2016 , net of reinsurance and indemnification, as well as cumulative claim frequency and the total of IBNR liabilities, including expected development on reported claims included within the net incurred losses and allocated LAE amounts. The tables are grouped by major product line and, if relevant, coverage.

As such, the difference between these claim counts and final claim counts once all claims have been identified and settled will tend to be higher in recent accident years, particularly the most recent accident year, due to claims closed without payment. Certain product lines, particularly the Company’s non-standard personal automobile insurance, tend to have a higher percentage of claims closed without payment. The Company's claims are counted at the feature level. As such, each claimant and each coverage is counted separately. For example, if for one occurrence, the Company's policyholder is at fault for damage to his/her own vehicle, another party's vehicle and three injured parties, there may be five features—three for bodily injury liability, one for property damage liability and one for first-party collision coverage. There may also be another feature for first-party medical payments. NOTE 6.

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 Consolidated Statements of Income in the period of change. In 2016 , the Company reduced its property and casualty insurance reserves by $20.7 million to recognize favorable development of loss and LAE reserves from prior accident years. Personal lines insurance loss and LAE reserves developed favorably by $16.8 million , and commercial lines insurance loss and LAE reserves developed favorably by $3.9 million . Personal automobile insurance loss and LAE reserves developed adversely by $11.3 million due primarily to the emergence of loss patterns that were worse than expected for liability insurance for the 2015 and 2014 accident years and, to a lesser extent, the 2013 and 2012 accident years. Homeowners insurance loss and LAE reserves developed favorably by $20.0 million due primarily to $16.8 million of favorable development on catastrophes primarily for the 2015 accident year and, to a lesser extent, the 2014 accident year. Other personal lines loss and LAE reserves developed favorably by $8.1 million due primarily to the emergence of more favorable loss patterns than expected for the 2015, 2014, 2013 and 2012 accident years. Commercial lines insurance loss and LAE reserves included adverse development of $2.4 million from continuing operations and favorable development of $6.3 million from discontinued operations. In 2015 , the Company reduced its property and casualty insurance reserves by $20.1 million to recognize favorable development of losses and LAE from prior accident years, including the impact of adverse development of $7.7 million , net of estimated indemnification recoveries, related to Alliance United for periods prior to the date of its acquisition. Personal lines NOTE 6. PROPERTY AND CASUALTY INSURANCE RESERVES (Continued) insurance loss and LAE reserves developed favorably by $13.3 million and commercial lines insurance loss and LAE reserves developed favorably by $6.8 million . Personal automobile insurance loss and LAE reserves developed favorably by $1.8 million , net of the adverse development related to Alliance United, homeowners insurance loss and LAE reserves developed favorably by $10.8 million , and other personal lines loss and LAE reserves developed favorably by $0.7 million . Excluding the adverse development related to Alliance United for periods prior to the date of its acquisition, personal lines insurance losses and LAE reserves developed favorably by $21.0 million due primarily to the emergence of more favorable loss patterns than expected for the 2013, 2012 and 2011 accident years. Commercial lines insurance loss and LAE reserves included adverse development of $1.8 million from continuing operations and favorable development of $8.6 million from discontinued operations. In 2014 , the Company reduced its property and casualty insurance reserves by $57.1 million to recognize favorable development of losses and LAE from prior accident years. Personal lines insurance loss and LAE reserves developed favorably by $50.9 million and commercial lines insurance loss and LAE reserves developed favorably by $6.2 million . Personal automobile insurance loss and LAE reserves developed favorably by $31.6 million , homeowners insurance loss and LAE reserves developed favorably by $14.8 million , and other personal lines loss and LAE reserves developed favorably by $4.5 million . The personal lines insurance losses and LAE reserves developed favorably due primarily to the emergence of more favorable loss patterns than expected for the three most recent prior accident years. Commercial lines insurance loss and LAE reserves included favorable development of $2.6 million from continuing operations and $3.6 million from discontinued operations. Commercial lines insurance losses and LAE reserves developed favorably from continuing operations due primarily to the emergence of more favorable loss patterns than expected for the 2013, 2011 and 2010 accident years. The Company cannot predict whether loss and LAE reserves will develop favorably or unfavorably from the amounts reported in the Consolidated Financial Statements. The Company believes that any such development will not have a material effect on the Company’s consolidated financial position, but could have a material effect on the Company’s consolidated financial results for a given period. Reinsurance and indemnification recoverables on property and casualty insurance reserves were $50.2 million and $52.0 million at December 31, 2016 and 2015 , respectively. These recoverables are concentrated with several reinsurers, the vast majority of which are highly rated by one or more of the principal investor and/or insurance company rating agencies. While most of these recoverables were unsecured at December 31, 2016 and 2015 , the agreements with the reinsurers generally provide for some form of collateralization upon the occurrence of certain events.

The credit agreement provides for fixed and floating rate advances for periods up to six months at various interest rates. The credit agreement contains various financial covenants, including limits on total debt to total capitalization, consolidated net worth and minimum risk-based capital ratios for Kemper’s largest insurance subsidiaries, Trinity and United Insurance. Proceeds from advances under the credit agreement may be used for general corporate purposes, including repayment of existing indebtedness. There were no outstanding borrowings under the credit agreement at either December 31, 2016 or December 31, 2015 . Trinity and United Insurance are members of the FHLB of Dallas and Chicago, respectively. During 2016 and 2015 , Trinity borrowed and repaid $10.0 million and $77.5 million , respectively, under its agreement with the FHLB of Dallas. During 2015 , United Insurance borrowed and repaid $21.0 million under its agreement with the FHLB of Chicago. There were no advances from the FHLB of Dallas or Chicago outstanding at either December 31, 2016 or December 31, 2015 . On February 24, 2015, Kemper issued $250.0 million of its 4.35% senior notes due February 15, 2025 (the “2025 Senior Notes”). The net proceeds of the issuance were $247.3 million , net of discount and transaction costs, for an effective yield of 4.49% . 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. Kemper used the net proceeds from the sale of the 2025 Senior Notes, together with available cash, to redeem in full the $250.0 million outstanding principal amount of its 6.00% senior notes due November 30, 2015. Kemper recognized a loss of $9.1 million before income taxes in the first quarter of 2015 from the early redemption of these senior notes. NOTE 7. DEBT (Continued) On February 27, 2014, Kemper issued $150.0 million of its 7.375% subordinated debentures due February 27, 2054 (the “2054 Debentures”). The net proceeds of the issuance were $144.0 million , net of discount and transaction costs, for an effective yield of 7.69% . The subordinated debentures are unsecured and are subordinated and junior to the senior indebtedness of Kemper. Interest on the subordinated debentures is payable quarterly. As long as no event of default has occurred, Kemper may defer interest payments on the subordinated debentures for up to five consecutive years without giving rise to an event of default. During a deferral period, interest will continue to accrue at the stated interest rate compounded quarterly. Kemper is permitted to redeem some or all of the subordinated debentures on or after February 27, 2019, at a redemption price that is equal to their principal amount plus accrued and unpaid interest. Kemper is permitted to redeem the subordinated debentures in whole, but not in part, at any time prior to February 27, 2019, within 90 days of the occurrence of certain tax events or rating agency events, at specified redemption prices. The Company anticipates issuing at least $250.0 million in 10 -year senior notes in the second quarter of 2017 to replace its Senior Notes due May 15, 2017. For risk management purposes, during the fourth quarter of 2016, the Company entered into a derivative transaction to hedge the risk of changes in the debt cash flows attributable to changes in the benchmark U.S. Treasury interest rate during the period leading up to the probable debt issuance (“Treasury Lock”). The Treasury Lock was formally designated as a cash flow hedge at inception and qualified for hedge accounting treatment. As such, the effective portion of the gain or loss on the derivative instrument is reported as a component of Other Comprehensive Income and will be amortized into earnings in the same periods that the hedged items affect earnings. The amortization will be included in Interest and Other Expenses, which is the same line item associated with the forecasted transaction. The ineffective portion of the change in fair value of the derivative instrument, if any, is recognized immediately in earnings. The fair value of the Treasury Lock of $1.6 million at December 31, 2016 has been included in Other Assets in the Consolidated Balance Sheet. As the entire amount of the change in fair value during the year was deemed effective, all of the change has been included entirely in Other Comprehensive Income for the year ended December 31, 2016. As the hedged transaction has yet to occur, no amounts have been reclassified from Other Comprehensive Income into earnings. If debt is issued in the second quarter of 2017 and its terms are consistent with what has been anticipated, the Company expects to reclassify $0.1 million of net gains on derivative instruments from AOCI to earnings for the year ended December 31, 2017 as interest expense on the debt is recognized.

Equity [Abstract]
Stockholders' Equity	NOTE 9. SHAREHOLDERS’ EQUITY Kemper is authorized to issue 20 million shares of $0.10 par value preferred stock and 100 million shares of $0.10 par value common stock. No preferred shares were issued or outstanding at December 31, 2016 and 2015 . There were 51,270,940 shares and 51,326,751 shares of common stock outstanding at December 31, 2016 and 2015 , respectively. Common stock outstanding included 16,000 shares and 80,848 shares at December 31, 2016 and 2015 , respectively, that have been issued, subject to certain vesting and other requirements, in connection with the Company’s long-term equity compensation plans. See Note 10 , “ Long-Term Equity-based Compensation ,” to the Consolidated Financial Statements for a discussion of the restrictions and vesting provisions. Kemper repurchased and retired 0.1 million shares of its common stock in open market transactions at an aggregate cost of $3.8 million in 2016 . Kemper repurchased and retired 1.2 million shares of its common stock in open market transactions at an aggregate cost of $43.5 million in 2015 . Kemper repurchased and retired 3.2 million shares of its common stock in open market transactions at an aggregate cost of $115.5 million in 2014 . Various state insurance laws restrict the amount that an insurance subsidiary may pay in the form of dividends, loans or advances without the prior approval of regulatory authorities. Also, that portion of an insurance subsidiary’s net equity which results from differences between statutory insurance accounting practices and GAAP would not be available for cash dividends, loans or advances. Kemper’s insurance subsidiaries paid dividends of $104.5 million to Kemper in 2016 . In 2017 , Kemper’s insurance subsidiaries would be able to pay $133 million in dividends to Kemper without prior regulatory approval. Kemper’s insurance subsidiaries had net assets of $2.4 billion , determined in accordance with GAAP, that were restricted from payment to Kemper without prior regulatory approval at December 31, 2016 . Kemper’s insurance subsidiaries are required to file financial statements prepared on the basis of statutory insurance accounting practices, a comprehensive basis of accounting other than GAAP. Statutory capital and surplus for the Company’s life and health insurance subsidiaries was $403.7 million and $394.6 million at December 31, 2016 and 2015 , respectively. Statutory net income for the Company’s life and health insurance subsidiaries was $29.7 million , $62.8 million and $100.7 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Statutory capital and surplus for the Company’s property and casualty insurance subsidiaries was $928.9 million and $957.7 million at December 31, 2016 and 2015 , respectively. Statutory net income for the Company’s property and casualty insurance subsidiaries was $1.4 million , $58.9 million and $85.7 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Statutory capital and surplus and statutory net income exclude parent company operations. Kemper’s insurance subsidiaries are also required to hold minimum levels of statutory capital and surplus to satisfy regulatory requirements. The minimum statutory capital and surplus, or company action level RBC, necessary to satisfy regulatory requirements for the Company’s life and health insurance subsidiaries collectively was $121.4 million at December 31, 2016 . The minimum statutory capital and surplus necessary to satisfy regulatory requirements for the Company’s property and casualty insurance subsidiaries collectively was $334.1 million at December 31, 2016 . Company action level RBC is the level at which a company is required to file a corrective action plan with its regulators and is equal to 200% of the authorized control level RBC. In 2016 , Kemper paid dividends of $49.2 million to its shareholders. Except for certain financial covenants under Kemper’s credit agreement or during any period in which Kemper elects to defer interest payments, there are no restrictions on Kemper’s ability to pay dividends to its shareholders. Certain financial covenants, namely minimum net worth and a maximum debt to total capitalization ratio, under Kemper’s credit agreement could limit the amount of dividends that Kemper may pay to shareholders at December 31, 2016 . Kemper had the ability to pay without restrictions $269 million in dividends to its shareholders and still be in compliance with all financial covenants under its credit agreement at December 31, 2016 .

Long-term Equity-based Compensa

Long-term Equity-based Compensation	12 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Long-Term Equity-Based Compensation	NOTE 10. LONG-TERM EQUITY-BASED COMPENSATION On May 4, 2011, Kemper’s shareholders approved the 2011 Omnibus Equity Plan (“Omnibus Plan”). The Omnibus Plan replaced the Company’s previous employee stock option plans, director stock option plan and restricted stock plan (collectively, the “Prior Plans”). Awards previously granted under the Prior Plans remain outstanding in accordance with their original terms. Beginning May 4, 2011, equity-based compensation awards may only be granted under the Omnibus Plan. A maximum number of 10,000,000 shares of Kemper common stock may be issued under the Omnibus Plan (the “Share Authorization”). As of December 31, 2016 , there were 6,762,714 common shares available for future grants under the Omnibus Plan, of which 682,752 shares were reserved for future grants based on the achievement of performance goals under the terms of outstanding performance-based restricted stock unit (“RSU”) awards. NOTE 10. LONG-TERM EQUITY-BASED COMPENSATION (Continued) The design of the Omnibus Plan provides for fungible use of shares to determine the number of shares available for future grants, with a fungible conversion factor of three to one, such that the Share Authorization will be reduced at two different rates, depending on the type of award granted. Each share of Kemper common stock issuable upon the exercise of stock options or stock appreciation rights will reduce the number of shares available for future grant under the Share Authorization by one share, while each share of Kemper common stock issued pursuant to “full value awards” will reduce the number of shares available for future grant under the Share Authorization by three shares. “Full value awards” are awards, other than stock options or stock appreciation rights, that are settled by the issuance of shares of Kemper common stock and include restricted stock, RSUs and deferred stock units (“DSUs”), if settled with stock, and other stock-based awards. Outstanding equity-based compensation awards at December 31, 2016 consisted of tandem stock option and stock appreciation rights (“Tandem Awards”), time-vested restricted stock, time-vested RSUs, performance-based RSUs and DSUs. Effective February 4, 2014, the Company began issuing time-based and performance-based RSUs. Recipients of restricted stock receive full dividend and voting rights on the same basis as all other outstanding shares of Kemper common stock. RSUs and DSUs give the recipient the right to receive one share of Kemper common stock for each RSU or DSU issued. Recipients of RSUs and DSUs receive full dividend equivalents on the same basis as all other outstanding shares of Kemper common stock, but do not receive voting rights until such shares are issued. Except as described below for equity-based compensation awards granted to each member of the Board of Directors who is not employed by the Company (“Non-employee Directors”), all outstanding awards are subject to forfeiture until certain restrictions have lapsed. For equity-based compensation awards with a graded vesting schedule, the Company recognizes compensation expense on a straight-line basis over the requisite service period for each separately-vesting portion of the awards as if each award were, in substance, multiple awards. Compensation expense is recognized only for those awards expected to vest, with forfeitures estimated at the date of grant based on the Company’s historical experience and future expectations. Equity-based compensation expense was $4.7 million , $6.5 million and $6.4 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Total unamortized compensation expense related to nonvested awards at December 31, 2016 was $8.1 million , which is expected to be recognized over a weighted-average period of 1.8 years . The Compensation Committee of the Board of Directors, or the Board’s authorized designee, has sole discretion to determine the persons to whom awards under the Omnibus Plan are granted, and the material terms of the awards. For Tandem Awards, material terms include the number of shares covered by such awards and the exercise price, vesting and expiration dates of such awards. Tandem Awards are non-transferable. The exercise price of Tandem Awards is the fair value of Kemper’s common stock on the date of grant. Employee Tandem Awards, time-based restricted stock awards and time-based RSU awards generally vest, beginning six months after date of grant, in four equal annual installments over a period of three and one-half years, with the Tandem Awards expiring ten years from the date of grant. Employee performance-based restricted stock and RSU awards generally vest over a period of three years, subject to achievement of performance goals and other restrictions. Under the Non-employee Director compensation programs in effect for 2016 , each non-employee director receives an annual DSU award covering shares of Kemper common with an aggregate grant date fair value of $75,000 at the conclusion of each annual shareholder meeting. Under the Non-employee Director compensation programs in effect for 2015 and 2014 , annual awards to each Non-employee Director included 500 DSUs and stock options, as described below. The DSUs granted to Non-employee Directors are fully vested on the date of grant. Conversion of the DSUs into shares of Kemper’s common stock is deferred until the date a director’s board service terminates. In addition to the annual DSU awards under the Non-employee Director compensation programs in effect for 2015 and 2014 , each Non-employee Director received an initial option award to purchase 4,000 shares of Kemper common stock immediately upon becoming a director, and in addition, received an annual option award to purchase 4,000 shares of common stock on the date of each annual meeting of Kemper’s shareholders. Grants of such option awards were fully vested and exercisable on the date of grant at an exercise price equal to the fair value of Kemper’s common stock on the date of grant and expire ten years from the date of grant. Prior to approval of the Omnibus Plan, the Company’s previous stock option plans included provisions, subject to certain limitations, to automatically grant restorative, or reload stock options (“Restorative Options”), to replace shares of previously owned Kemper common stock that an exercising option holder surrenders, either actually or constructively, to satisfy the exercise price and/or tax withholding obligations relating to the exercise. The restorative feature was eliminated prospectively for original option awards granted on or after February 3, 2009. However, Restorative Options could still be granted, subject to certain limitations, in connection with the exercise of original options granted before February 3, 2009. Following the exercise in 2016 of original options previously granted prior to February 3, 2009 and the automatic grant of Restorative Options in NOTE 10. LONG-TERM EQUITY-BASED COMPENSATION (Continued) connection with such exercise, there were no options outstanding at December 31, 2016 that were eligible to receive a grant of a Restorative Option. Restorative Options are subject to the same terms and conditions as the original options, including the expiration date, except that the exercise price is equal to the fair value of Kemper common stock on the date of grant of a Restorative Option and cannot be exercised until six months after the date of grant. The grant of a Restorative Option does not result in an increase in the total number of shares and options held by an employee, but changes the mix of the two. The Company uses the Black-Scholes option pricing model to estimate the fair value of each Tandem Award on the date of grant. The expected terms of Tandem Awards are developed by considering the Company’s historical Tandem Award exercise experience, demographic profiles, historical share retention practices of employees and assumptions about their propensity for early exercise in the future. Expected volatility is estimated using weekly historical volatility. The Company believes that historical volatility is currently the best estimate of expected volatility. The dividend yield in 2016 , 2015 and 2014 was calculated by taking the natural logarithm of the annualized yield divided by the Kemper common stock price on the date of grant. The risk-free interest rate was the yield on the grant date of U.S. Treasury zero coupon issues with a maturity comparable to the expected term of the option. The assumptions used in the Black-Scholes pricing model for Tandem Awards granted during the years ended December 31, 2016 , 2015 and 2014 are presented below. 2016 2015 2014 RANGE OF VALUATION ASSUMPTIONS Expected Volatility 25.85 % - 42.19 % 21.31 % - 41.65 % 25.76 % - 44.43 % Risk-free Interest Rate 0.77 - 2.01 1.08 - 1.96 1.07 - 2.14 Expected Dividend Yield 2.22 - 3.41 2.37 - 2.62 2.53 - 2.60 WEIGHTED-AVERAGE EXPECTED LIFE IN YEARS Employee Grants 1 - 6.5 4 - 7 4 - 7 Director Grants N/A 5.5 6 Tandem Award activity for the year ended December 31, 2016 is presented below.

Total intrinsic value of Tandem Awards exercised was $2.0 million , $4.6 million and $0.4 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Cash received from exercises of Tandem Awards was $3.5 million , $3.9 million and $0.5 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Total tax benefit realized for tax deductions from exercises of Tandem Awards was $0.7 million , $1.6 million and $0.1 million for the years ended December 31, 2016 , 2015 and 2014 , respectively.

Activity related to nonvested time-based restricted stock and nonvested time-based RSUs for the year ended December 31, 2016 is presented below. Time-based Restricted Stock Awards Time-based RSU Awards Number of Shares Weighted- average Grant-date Fair Value Per Share Number of RSUs Weighted- average Grant-date Fair Value Per RSU Nonvested Balance at Beginning of the Year 29,448 $ 33.77 85,048 $ 36.84 Granted — — 118,622 31.48 Vested (12,098 ) 32.32 (26,006 ) 33.01 Forfeited (1,350 ) 35.75 (19,303 ) 36.03 Nonvested Balance at December 31, 2016 16,000 $ 34.69 158,361 $ 33.56 Prior to February 3, 2009, only awards of time-vested restricted stock had been granted. Beginning on February 3, 2009, in addition to time-vested restricted stock granted to certain employees and officers, the Company began making performance-based restricted awards to certain officers and employees. The initial number of shares or RSUs awarded to each participant of a performance-based award represents the shares that would vest, or, in the case of a RSU, that would vest and would be issued, if the performance level attained were to be at the “target” performance level. For performance above the target level, each participant would receive a grant of additional shares of stock up to a maximum of 100% of the initial number of shares or RSUs awarded to the participant. The final payout of these awards, and any forfeitures of shares for performance below the “target” performance level, will be determined based on the Company’s performance. If, at the end of the applicable performance period, the Company’s performance: • exceeds the “target” performance level, additional shares of stock will be issued to the award recipient; • is below the “target” performance level, but at or above a “minimum” performance level, only a portion of the shares of performance-based restricted stock or RSUs originally issued to the award recipient will vest; or • is below a “minimum” performance level, none of the shares of performance-based restricted stock or RSUs originally issued to the award recipient will vest. NOTE 10. LONG-TERM EQUITY-BASED COMPENSATION (Continued) Activity related to nonvested performance-based restricted stock and nonvested performance-based RSU awards for the year ended December 31, 2016 is presented below. Performance-based Restricted Stock Awards Performance-based RSU Awards Number of Shares Weighted- average Grant-date Fair Value Per Share Number of RSUs Weighted- average Grant-date Fair Value Per RSU Nonvested Balance at Beginning of the Year 51,400 $ 42.12 128,100 $ 41.85 Granted — — 146,788 29.62 Forfeited (51,400 ) 42.12 (47,304 ) 39.04 Nonvested Balance at December 31, 2016 — $ — 227,584 $ 34.55 The number of additional shares that would be granted if the Company were to meet or exceed the maximum performance levels related to the outstanding performance-based awards for the 2016 and 2015 three-year performance periods was 137,615 common shares and 46,762 common shares, respectively, (as “full value awards,” the equivalent of 412,845 shares and 140,286 shares, respectively, under the Share Authorization) at December 31, 2016 . For the 2014 three-year performance period, the Company’s performance level was below the minimum performance level, and all of the related 43,207 shares of performance-based RSUs were forfeited on February 4, 2017, the three-year anniversary of their grant date. For the 2013 three-year performance period, the Company’s performance level was below the minimum performance level, and all of the related 51,400 shares of performance-based restricted shares were forfeited on February 4, 2016, the three-year anniversary of their grant date. The grant date fair values of the performance-based restricted stock and performance-based RSU awards with a market performance condition are determined using the Monte Carlo simulation method. The Monte Carlo simulation model produces a risk-neutral simulation of the daily returns on the common stock of Kemper and each of the other companies included in the peer group. Returns generated by the simulation depend on the risk-free interest rate used and the volatilities of, and the correlation between, these stocks. The model simulates stock prices and dividend payouts to the end of the three-year performance period. Total shareholder returns are generated for each of these stocks based on the simulated prices and dividend payouts. The total shareholder returns are then ranked, and Kemper’s simulated ranking is converted to a payout percentage based on the terms of the performance-based restricted stock and performance-based RSU awards. The payout percentage is applied to the simulated stock price at the end of the performance period, reinvested dividends are added back, and the total is discounted to the valuation date at the risk-free rate. This process is repeated approximately ten thousand times, and the grant date fair value is equal to the average of the results from these trials. Performance-based awards outstanding on January 1, 2016 are measured using a market performance condition. Fair value for these awards was estimated using the Monte Carlo simulation method described above. For awards outstanding on January 1, 2016, the final payout of these awards, and any forfeitures of shares for performance below the “target” performance level, are determined based on Kemper’s total shareholder return, relative to a peer group comprised of all the companies in the S&P Supercomposite Insurance Index, over the respective three-year performance period ending on either December 31, 2017, 2016 or 2015, depending on the three-year performance period being measured. Compensation cost for these awards is recognized ratably over the requisite service period. In the event that the market performance condition is not satisfied, previously recognized compensation cost would not reverse, but it would reverse if the requisite service period is not met. Half of the performance-based RSUs granted in 2016 are measured using a market performance condition. Fair value for these awards was estimated using the Monte Carlo simulation method described above. Final payout for these awards, and any forfeitures of shares for performance below the “target” performance level, will be based on Kemper’s total shareholder return, relative to a peer group comprised of all the companies in the S&P Supercomposite Insurance Index, over a three-year performance period ending on February 28, 2019. Compensation cost for these awards is recognized ratably over the requisite service period. In the event that the market performance condition is not satisfied, previously recognized compensation cost would not reverse, but it would reverse if the requisite service period is not met. NOTE 10. LONG-TERM EQUITY-BASED COMPENSATION (Continued) Half of the performance-based RSUs granted in 2016 are measured solely using a Company-specific metric. Final payout for these awards, and any forfeitures of shares for performance below the “target” performance level, will be determined based on Kemper’s adjusted return on equity over a three-year performance period ending on December 31, 2018. Fair value for these awards was determined using the closing price of Kemper common stock on the date of grant. Accruals of compensation cost for these awards are estimated based on the probable outcome of the performance condition. The total fair value of time-vested and performance-based restricted stock and RSUs that vested during the year ended December 31, 2016 was $1.3 million . The tax benefits for tax deductions realized from such shares was $0.5 million . The total fair value of the shares of time-vested and performance-based restricted stock that vested during the year ended December 31, 2015 was $1.4 million . The tax benefits for tax deductions realized from such shares was $0.5 million . The total fair value of the shares of time-vested and performance-based restricted stock that vested during the year ended December 31, 2014 and the 2011 Additional Shares was $3.6 million . The tax benefits for tax deductions realized from such shares was $1.2 million . The grant-date fair values of DSU awards granted to Non-employee Directors are determined using the closing price of Kemper common stock on the date of grant. The total fair value of DSUs that vested during the years ended December 31, 2016 , 2015 and 2014 was $0.5 million , $0.1 million and $0.2 million , respectively.

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.

Pension Benefits	NOTE 16. PENSION BENEFITS 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 Pension Plan is generally non-contributory, but participation requires or required some employees to contribute 3% of pay, as defined, per year. Benefits for participants who are or were required to contribute to the Pension Plan are based on compensation during plan participation and the number of years of participation. Benefits for the vast majority of participants who are not required to contribute to the Pension Plan are based on years of service and final average pay, as defined. The Company funds the Pension Plan in accordance with the requirements of ERISA. 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 pension loss of $167.9 million as of the re-measurement date 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 5 years , the remaining average service life of active participants. NOTE 16.

The assets of the Pension Plan may be invested in fixed income and equity investments or any other investment vehicle or financial instrument deemed appropriate. Fixed income investments may include cash and short-term instruments, U.S. Government securities, corporate bonds, mortgages and other fixed income investments.

The Pension Plan has not invested in Kemper common stock. NOTE 16. PENSION BENEFITS (Continued) The trust investment committee for the Pension Plan, along with its third party fiduciary advisor, periodically reviews the performance of the Pension Plan’s investments and asset allocation. Several external investment managers, one of which is Fayez Sarofim & Co. (see Note 24 , “ Related Parties ,” to the Consolidated Financial Statements), manage the equity investments of the trust for the Pension Plan. Each manager is allowed to exercise investment discretion, subject to limitations, if any, established by the trust investment committee for the Pension Plan. All other investment decisions are made by the Company, subject to general guidelines as set by the trust investment committee for the Pension Plan. The Company determines its Expected Long Term Rate of Return on Plan Assets based primarily on the Company’s expectations of future returns, with consideration to historical returns, for the Pension Plan’s investments, based on target allocations of the Pension Plan’s investments.

PENSION BENEFITS (Continued) The actuarial loss included in AOCI at December 31, 2016 is being amortized over approximately 24 years , the remaining average estimated life expectancy of participants. The Company estimates that Pension Expense for the Pension Plan for the year ended December 31, 2017 will include expense of $2.5 million resulting from the amortization of the related accumulated actuarial loss included in AOCI at December 31, 2016 . 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. See Note 2, “Summary of Accounting Policies and Accounting Changes,” to the Consolidated Financial Statements for further discussion of the change. The weighted-average discount rate, service cost discount rate, interest cost discount rate, rate of increase in future compensation levels and expected long-term rate of return on plan assets used to develop the components of Pension Expense for the Pension Plan for the periods presented below were: Years Ended December 31, 5/13/16 to 12/31/16 1/1/16 to 5/12/16 2015 2014 Weighted-average Discount Rate 3.94 % 4.47 % 4.10 % 4.90 % Service Cost Discount Rate 4.22 4.78 — — Interest Cost Discount Rate 3.18 3.69 — — Rate of Increase in Future Compensation Levels 3.15 3.15 3.31 3.05 Expected Long Term Rate of Return on Plan Assets 6.25 6.25 6.75 7.00 On August 12, 2016, the Company made a voluntary cash contribution of $9.0 million to the Pension Plan. The Company did not contribute to the Pension Plan in 2015 or 2014 . The Company does not expect that it will be required to contribute to the Pension Plan in 2017 , but could make a voluntary contribution pursuant to the maximum funding limits under ERISA. The following benefit payments (net of participant contributions), which consider expected future service of certain participants that remain eligible for a benefit accrual, as appropriate, are expected to be paid from the Pension Plan: DOLLARS IN MILLIONS Years Ending December 31, 2017 2018 2019 2020 2021 2022-2026 Estimated Pension Benefit Payments $ 27.6 $ 28.8 $ 29.9 $ 30.9 $ 31.9 $ 170.0 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 at the re-measurement date. 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. The unfunded liability related to the Supplemental Plan was $25.4 million and $30.4 million at December 31, 2016 and 2015 , respectively. Pension income for the Supplemental Plan was $1.0 million for the year ended December 31, 2016 , compared to pension expense of $2.1 million and $1.8 million for the years ended December 31, 2015 , and 2014 , respectively. An actuarial gain of $4.8 million before taxes, an actuarial gain of $1.5 million before taxes and an actuarial loss of $7.0 million before taxes are included in Other Comprehensive Income (Loss) for the years ended December 31, 2016 , 2015 and 2014 , respectively. The Company also sponsors several defined contribution benefit plans covering most of its employees. The Company made contributions to those plans of $8.4 million , $7.8 million and $7.3 million in 2016 , 2015 and 2014 , respectively.

Postemployment Benefits Other Than Pensions	NOTE 17. POSTRETIREMENT BENEFITS OTHER THAN PENSIONS The Company sponsors an other than pension postretirement employee benefit plan (“OPEB”) that provides medical, dental and/or life insurance benefits to approximately 500 retired and 225 active employees (the “OPEB Plan”). The Company has historically self-insured the benefits under the OPEB Plan. The medical plan generally provides for a limited number of years of medical insurance benefits at retirement based on the participant’s attained age at retirement and number of years of service until specified dates and generally has required participant contributions, with most contributions adjusted annually. On December 30, 2016, the Company amended the OPEB Plan and, effective December 31, 2016, will no longer offer coverage to post-65 Medicare-eligible retirees and Medicare-eligible spouses under the self-insured portion of its coverage. Rather, beginning on January 1, 2017, the OPEB Plan will offer access to a private, third-party Medicare exchange and will provide varying levels of a Company-determined subsidy via health reimbursement accounts to certain Medicare-eligible retirees and spouses in order to help fund a portion of the participants’ cost. Further, the amendment eliminates the requirement for such participants to contribute to the OPEB Plan. In conjunction with the amendment, the Company recorded a pre-tax reduction to its Accumulated Postretirement Benefit Obligation of $11.0 million through Other Comprehensive Income. This prior service credit will be amortized into income over the remaining average life of the OPEB Plan’s participants.

Segment Reporting [Abstract]
Business Segments	NOTE 18. BUSINESS SEGMENTS The Company is engaged, through its subsidiaries, in the property and casualty insurance and life and health insurance businesses. The Company conducts its operations through two operating segments: Property & Casualty Insurance and Life & Health Insurance. The Property & Casualty Insurance segment’s principal products are personal automobile insurance, both preferred and nonstandard, homeowners insurance, other personal insurance and commercial automobile insurance. These products are distributed primarily through independent agents and brokers. The Life & Health Insurance segment’s principal products are individual life, accident, health and property insurance. These products are distributed by career agents employed by the Company and independent agents and brokers. The Company’s earned premiums are derived in the United States. The accounting policies of the segments are the same as those described in Note 2 , “ Summary of Accounting Policies and Accounting Changes ,” to the Consolidated Financial Statements. Capital expenditures for long-lived assets by operating segment are immaterial. It is the Company’s management practice to allocate certain corporate expenses, primarily compensation costs for corporate employees and related facility costs, included in Interest and Other Expenses in the Consolidated Statements of Income to its insurance operations. The amount of such allocated corporate expenses was $52.9 million , $43.4 million and $42.1 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. The Company does not allocate Net Realized Gains on Sales of Investments, Net Impairment Losses Recognized in Earnings, interest expense on debt or postretirement benefit plans, and actuarial gains and losses on its postretirement benefit plans to its operating segments.

Reinsurance Disclosures [Abstract]
Catastrophe Reinsurance	NOTE 20. CATASTROPHE REINSURANCE Catastrophes and natural disasters are inherent risks of the property and casualty insurance business. These catastrophic events and natural disasters include, without limitation, hurricanes, tornadoes, earthquakes, hailstorms, wildfires, high winds and winter storms. Such events result in insured losses that are, and will continue to be, a material factor in the results of operations and financial position of the Company’s property and casualty insurance companies. Further, because the level of these insured losses occurring in any one year cannot be accurately predicted, these losses may contribute to material year-to-year fluctuations in the results of operations and financial position of these companies. Specific types of catastrophic events are more likely to occur at certain times within the year than others. This factor adds an element of seasonality to property and casualty insurance claims. The Company has adopted the industry-wide catastrophe classifications of storms and other events promulgated by ISO to track and report losses related to catastrophes. ISO classifies a disaster as a catastrophe when the event causes $25.0 million or more in direct insured losses to property and affects a significant number of policyholders and insurers. ISO-classified catastrophes are assigned a unique serial number recognized throughout the insurance industry. The discussions that follow utilize ISO’s definition of catastrophes. The Company manages its exposure to catastrophes and other natural disasters through a combination of geographical diversification, restrictions on the amount and location of new business production in certain regions, and reinsurance. To limit its exposures to catastrophic events, the Company maintains various catastrophe reinsurance programs for its property and casualty insurance businesses. NOTE 20. CATASTROPHE REINSURANCE (Continued) Coverage for the Property & Casualty Insurance segment’s primary catastrophe reinsurance program effective January 1, 2016 to December 31, 2016 is provided in various layers as presented below.

DOLLARS IN MILLIONS Catastrophe Losses and LAE Percentage of Coverage In Excess of Up to Property & Casualty Insurance Segment: Retained $ — $ 50.0 — % 1st Layer of Coverage 50.0 100.0 95.0 2nd Layer of Coverage 100.0 200.0 95.0 3rd Layer of Coverage 200.0 400.0 95.0 In the event that the Property & Casualty Insurance segment’s incurred catastrophe losses and LAE covered by any of its catastrophe reinsurance programs presented in the three preceding tables exceed the retention for that particular layer, each of the programs required one reinstatement of such coverage. In such an instance, the Property & Casualty Insurance segment is required to pay a reinstatement premium to the reinsurers to reinstate the full amount of reinsurance available under such layer. The Property & Casualty Insurance segment’s catastrophe reinsurance in 2016 , 2015 and 2014 also included reinsurance coverage from the Florida Hurricane Catastrophe Fund (the “FHCF”) for hurricane losses in Florida at retentions lower than those described above. The Life & Health Insurance segment also purchases reinsurance from the FHCF for hurricane losses in Florida. Except for the coverage provided by the FHCF, the Life & Health Insurance segment has not carried any other catastrophe reinsurance since 2012, primarily due to actions taken by the Life & Health Insurance segment to reduce its exposures to catastrophes. NOTE 20. CATASTROPHE REINSURANCE (Continued) Reinsurance premiums for the Company’s primary catastrophe reinsurance programs and the FHCF Program reduced earned premiums for the years ended December 31, 2016 , 2015 and 2014 by the following: DOLLARS IN MILLIONS 2016 2015 2014 Property & Casualty Insurance $ 11.9 $ 12.8 $ 17.6 Life & Health Insurance 0.1 0.1 0.1 Total Ceded Catastrophe Reinsurance Premiums $ 12.0 $ 12.9 $ 17.7 Catastrophe losses and LAE (including reserve development), net of reinsurance recoveries, for the years ended December 31, 2016 , 2015 and 2014 by business segment are presented below. DOLLARS IN MILLIONS 2016 2015 2014 Property & Casualty Insurance $ 90.4 $ 56.6 $ 80.7 Life & Health Insurance 5.4 3.9 3.1 Total Catastrophe Losses and LAE $ 95.8 $ 60.5 $ 83.8 Total catastrophe loss and LAE reserves, net of reinsurance recoverables, developed favorably by $19.3 million , $7.8 million and $14.7 million in 2016 , 2015 and 2014 , respectively. The Property & Casualty Insurance segment reported favorable catastrophe reserve development of $19.2 million , $7.9 million and $15.8 million in 2016 , 2015 and 2014 , respectively. The Life & Health Insurance segment reported favorable catastrophe reserve development of $0.1 million in 2016 , adverse catastrophe reserve development of $0.1 million in 2015 and adverse catastrophe reserve development of $1.1 million in 2014 . The process of estimating and establishing reserves for catastrophe losses is inherently uncertain and the actual ultimate cost of a claim, net of actual reinsurance recoveries, may vary materially from the estimated amount reserved. The Company’s estimates of direct catastrophe losses are generally based on inspections by claims adjusters and historical loss development experience for areas that have not been inspected or for claims that have not yet been reported. The Company’s estimates of direct catastrophe losses are based on the coverages provided by its insurance policies. The Company’s homeowners and dwelling insurance policies do not provide coverage for losses caused by floods, but generally provide coverage for physical damage caused by wind or wind-driven rain. Accordingly, the Company’s estimates of direct losses for homeowners and dwelling insurance do not include losses caused by flood. Depending on the policy, automobile insurance may provide coverage for losses caused by flood. Estimates of the number and severity of claims ultimately reported are influenced by many variables, including, but not limited to, repair or reconstruction costs and determination of cause of loss that are difficult to quantify and will influence the final amount of claim settlements. All these factors, coupled with the impact of the availability of labor and material on costs, require significant judgment in the reserve setting process. A change in any one or more of these factors is likely to result in an ultimate net claim cost different from the estimated reserve. The Company’s estimates of indirect losses from wind pools and joint underwriting associations are based on a variety of factors, including, but not limited to, actual or estimated assessments provided by or received from such entities, insurance industry estimates of losses, and estimates of the Company’s market share in the assessable states. Actual assessments may differ materially from these estimated amounts.

Other Reinsurance	NOTE 21. OTHER REINSURANCE In addition to the reinsurance programs described in Note 20 , “ Catastrophe Reinsurance ,” to the Consolidated Financial Statements, Kemper’s insurance subsidiaries utilize other reinsurance arrangements to limit their maximum loss, provide greater diversification of risk and to minimize exposures on larger risks. The ceding of insurance does not discharge the primary liability of the original insurer. Accordingly, insurance reserve liabilities are reported gross of any estimated recovery from reinsurers in the Consolidated Balance Sheets. Amounts recoverable from reinsurers are estimated in a manner consistent with the insurance reserve liability and are included in Other Receivables in the Consolidated Balance Sheets. Earned Premiums ceded on long-duration and short-duration policies were $19.0 million , $20.6 million and $26.0 million for the years ended December 31, 2016 , 2015 and 2014 , respectively, of which $12.0 million , $12.9 million and $17.7 million , respectively, was related to catastrophe reinsurance. See Note 20 , “ Catastrophe Reinsurance ,” to the Consolidated Financial Statements for additional information regarding the Company’s catastrophe reinsurance programs. Certain insurance subsidiaries assume business from other insurance companies and involuntary pools. Earned Premiums assumed on long-duration and short-duration policies were $67.3 million , $60.0 million and $57.1 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Trinity and Capitol County Mutual Fire Insurance Company (“Capitol”) are parties to a quota share reinsurance agreement whereby Trinity assumes 100% of the business written by Capitol, subject to a cap, for ceded losses for dwelling coverage. Earned Premiums assumed by Trinity from Capitol were $21.3 million , $21.8 million and $21.9 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Capitol is a mutual insurance company and, accordingly, is owned by its policyholders. Trinity and Old Reliable Casualty Company (“ORCC”), a subsidiary of Capitol, are parties to a quota share reinsurance agreement whereby Trinity assumes 100% of the business written by ORCC, subject to a cap for ceded losses for dwelling coverage. Earned Premiums assumed by Trinity from ORCC were $6.2 million , $6.5 million and $6.7 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Five employees of the Company serve as directors of Capitol’s five member board of directors. Nine employees of the Company also serve as directors of ORCC’s nine member board of directors. Kemper’s subsidiary, United Insurance, provides claims and administrative services to Capitol and ORCC. In addition, agents appointed by Kemper’s subsidiary, The Reliable Life Insurance Company, and who are employed by United Insurance, are also appointed by Capitol and ORCC to sell property insurance products for the Company’s Life & Health Insurance segment. The Company also provides certain investment services to Capitol and ORCC.

Fair Value Measurements	NOTE 22. 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 a derivative instrument that is classified as a cash flow hedge and reported in Other Assets at fair value at December 31, 2016 . The Company has no material liabilities that are measured and reported at fair value. The valuation of assets measured at fair value in the Company’s Consolidated Balance Sheet at December 31, 2016 is summarized below.

The Company’s investments in Equity Securities that are classified as Level 1 in the two preceding tables consist either of 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 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 NOTE 22. FAIR VALUE MEASUREMENTS (Continued) 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 or 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 December 31, 2016 . DOLLARS IN MILLIONS Unobservable Input Total Fair Value Range of Unobservable Inputs Weighted Average Yield Investment-grade Market Yield $ 106.1 2.7 % - 5.1 % 3.8 % Non-investment-grade: Senior Debt Market Yield 142.2 4.8 - 14.0 9.6 Junior Debt Market Yield 143.3 9.5 - 20.0 13.0 Collateralized Loan Obligations Market Yield 103.5 3.7 - 9.9 6.3 Other Various 16.0 Total Fixed Maturity Investments in Corporate Securities $ 511.1 NOTE 22.

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, 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. Information by security type pertaining to the changes in the fair value of the Company’s investments classified as Level 3 for the year ended December 31, 2016 is presented below.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	NOTE 23. 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 information related to the 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 its life insurance records against one or more death verification databases to determine if any of its insureds may be deceased. See Note 2 , “ Summary of Accounting Policies and Accounting Changes ,” to the Consolidated Financial Statements for discussion of the estimated financial impact of such voluntary action recognized in the Company’s 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.

(“FS&C”), a registered investment advisory firm. FS&C provided investment management services with respect to certain assets of Kemper’s subsidiary, Trinity, under an agreement between the parties. Trinity had $85.8 million in assets managed by FS&C at December 31, 2014 . In 2014, Trinity began reducing the amount of assets managed by FS&C. Trinity completed the disposal of all the assets managed by FS&C in 2015 . Investment Expenses incurred in connection with such agreement were $0.1 million and $0.3 million for the years ended December 31, 2015 , and 2014 , respectively. The Company’s Pension Plan had $148.4 million , $137.2 million and $159.2 million in assets managed by FS&C at December 31, 2016 , 2015 and 2014 , respectively, under an agreement with FS&C whereby FS&C provides investment management services with respect to certain funds of the plan.

Summary Of Accounting Policie37

Summary Of Accounting Policies And Accounting Changes (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Investments	Investments Investments in Fixed Maturities include bonds, notes and redeemable preferred stocks. Investments in Fixed Maturities are classified as available for sale and reported at fair value. Net Investment Income, including amortization of purchased premiums and accretion of market discounts, on Investments in Fixed Maturities is recognized as interest over the period that it is earned using the effective yield method. Investments in Equity Securities include common and non-redeemable preferred stocks and other equity interests and are reported at fair value. Investments in common and non-redeemable preferred stocks with readily determinable fair values are classified as available for sale. Dividend income on investments in common and non-redeemable preferred stocks is recognized on the ex-dividend date. Other equity interests primarily consist of exchange traded funds and interests in limited liability companies and limited partnerships in which the Company’s interests are deemed minor. The Company’s share of distributed earnings from other equity interests is recognized as dividend income when received. Unrealized appreciation or depreciation, net of applicable deferred income taxes, on fixed maturities and equity securities classified as available for sale is reported in Accumulated Other Comprehensive Income (“AOCI”) included in Shareholders’ Equity. 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. NOTE 2. SUMMARY OF ACCOUNTING POLICIES AND ACCOUNTING CHANGES (Continued) Fair Value Option Investments include investments in certain hedge funds, which the Company has elected the fair value option (“FVO”) to account for such investments. Under the FVO method of accounting, the Company reports changes in the fair value of such investments in Net Investment Income in the Consolidated Statements of Income. The hedge funds are designed to preserve liquidity, while providing higher returns than Kemper would otherwise expect to earn had it invested in other short-term investments. Short-term Investments include certificates of deposits and other fixed maturities that mature within one year from the date of purchase, U.S. Treasury bills, money market mutual funds, overnight interest bearing accounts, and repurchase agreements. Short-term Investments are reported at cost, which approximates fair value. Other Investments primarily include loans to policyholders and real estate. Loans to policyholders are carried at unpaid principal balance. Real estate is carried at cost, net of accumulated depreciation. Real estate is depreciated over the estimated useful life of the asset using the straight-line method of depreciation. Real estate is evaluated for impairment when events or circumstances indicate the carrying value may not be recoverable. An impairment loss on real estate is recognized when the carrying value exceeds the sum of undiscounted projected future cash flows as well as the fair value, or, in the case of a property classified as held for sale, when the carrying value exceeds the fair value, net of costs to sell. Gains and losses on sales of investments are computed on the specific identification method and are reported in the Consolidated Statements of Income in the period in which the sales occur. The Company regularly reviews its investment portfolio for factors that may indicate that a decline in fair value of an investment is other than temporary. Losses are computed on the specific identification method and reported in the Consolidated Statements of Income in the period that the decline is determined to be other than temporary. The portion of an impairment of an investment in a fixed maturity attributed to a credit loss is reported in Net Impairment Losses Recognized in Earnings in the Consolidated Statements of Income, with the portion of the impairment that is not attributed to a credit loss reported in AOCI.
Fair Value Measurements	Fair Value Measurements The Company uses a hierarchical framework which prioritizes and ranks the market observability of inputs used in fair value measurements. Market price observability is affected by a number of factors, including the type of asset or liability and the characteristics specific to the asset or liability being measured. Assets and liabilities with readily available, active, quoted market prices or for which fair value can be measured from actively quoted prices generally are deemed to have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. The Company classifies the inputs used to measure fair value into one of three levels as follows: • Level 1 — Quoted prices in an active market for identical assets or liabilities; • Level 2 — Observable inputs other than Level 1, quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, and model-derived prices whose inputs are observable or whose significant value drivers are observable; and • Level 3 — Unobservable inputs for the asset or liability being measured. Observable inputs are based on market data obtained from independent sources, while unobservable inputs are based on the Company’s market assumptions. Unobservable inputs require significant management judgment or estimation. In some cases, the inputs used to measure an asset or liability may fall into different levels of the fair value hierarchy. In those cases, the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level of input that is significant to the entire measurement. Such determination requires significant management judgment. However, in accordance with GAAP, the Company is not permitted to use management judgment to adjust quoted market prices in an active market.
Deferred Policy Acquisition Costs	Deferred Policy Acquisition Costs Costs directly associated with the successful acquisition of business, principally commissions and certain premium taxes and policy issuance costs, are deferred. Costs deferred on property and casualty insurance contracts and short duration health insurance contracts are amortized over the period in which premiums are earned. Costs deferred on traditional life insurance products and other long-duration insurance contracts are primarily amortized over the anticipated premium-paying period of the related policies in proportion to the ratio of the annual premiums to the total premiums anticipated, which is estimated using the same assumptions used in calculating policy reserves.
Goodwill	Goodwill The cost of an acquired entity over the fair value of net assets acquired is reported as Goodwill. Goodwill is not amortized, but rather is tested for recoverability annually or when certain triggering events require testing.
Insurance Reserves	Insurance Reserves Reserves for losses and LAE on property and casualty insurance coverage and health insurance coverage represent the estimated claim cost and loss adjustment expense necessary to cover the ultimate net cost of investigating and settling all losses incurred and unpaid at the end of any given accounting period. Such estimates are based on individual case estimates for reported claims and estimates for incurred but not reported (“IBNR”) losses, including expected development on reported claims. These estimates are adjusted in the aggregate for ultimate loss expectations based on historical experience patterns and current economic trends, with any change in the estimated ultimate liabilities being reported in the Consolidated Statements of Income in the period of change. Changes in such estimates may be material. For traditional life insurance products, the reserves for future policy benefits are estimated on the net level premium method using assumptions as of the issue date for mortality, interest, policy lapses and expenses, including provisions for adverse mortality. These assumptions vary by such characteristics as plan, age at issue and policy duration. Mortality assumptions are based on the Company’s historical experience and industry standards. Interest rate assumptions principally range from 3% to 7% . Lapse rate assumptions are based on actual and industry experience. 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 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 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 the year ended December 31, 2016 include a charge of $77.8 million to recognize the initial 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.
Other Receivables	Other Receivables Other Receivables primarily include reinsurance recoverables and accrued investment income. Reinsurance Recoverables were $106.4 million and $108.3 million at December 31, 2016 and 2015 , respectively. Accrued Investment Income was $70.8 million and $68.5 million at December 31, 2016 and 2015 , respectively.
Other Assets	Other Assets Other Assets primarily include property and equipment, internal use software, insurance licenses acquired in business combinations, the value of other intangible assets acquired, corporate-owned life insurance and prepaid expenses. Property and equipment is depreciated over the useful lives of the assets, generally using the straight-line or double declining balance methods of depreciation depending on the asset involved. Internal use software is amortized over the useful life of the asset using the straight-line method of amortization. Write-offs of Long-lived Assets for the year ended December 31, 2015 was a charge of $11.1 million to write off the costs of a computer software development project that was abandoned by the Company’s Property & Casualty Insurance segment. Write-offs of Long-lived Assets for the year ended December 31, 2014 was a charge of $54.6 million to write off certain software for the Company’s Property & Casualty Insurance segment after the Company determined that it was no longer probable that the software would be fully implemented. Insurance licenses acquired in business combinations and other indefinite life intangibles are not amortized, but rather tested periodically for recoverability. NOTE 2. SUMMARY OF ACCOUNTING POLICIES AND ACCOUNTING CHANGES (Continued) Corporate-owned life insurance is reported at cash surrender value with changes due to cost of insurance and investment experience reported in Other Income in the Consolidated Statements of Income. The Company accounts for the present value of the future profits embedded in life insurance in force acquired (“Life VIF”) based on actuarial estimates of the present value of estimated net cash flows. Life VIF was $28.9 million and $32.5 million at December 31, 2016 and 2015 , respectively. Life VIF is amortized using the effective interest method using interest rates consistent with the rates in the underlying insurance contracts. The Company estimates that it will record Life VIF amortization, net of interest, of $3.1 million in 2017, $2.8 million in 2018, $2.4 million in 2019, $2.0 million in 2020 and $1.8 million in 2021. The Company evaluates the Life VIF for recoverability annually. The Company accounts for the present value of the future profits embedded in Property and Casualty Insurance Customer Relationships Acquired (“P&C Customer Relationships”) based on the present value of estimated future cash flows from the customer relationships acquired. P&C Customer Relationships was $9.0 million and $11.2 million at December 31, 2016 and 2015 , respectively. P&C Customer Relationships is amortized using the effective interest method. P&C Customer Relationships is tested for recoverability using undiscounted projections of future cash flows and written down to estimated fair value if the carrying value exceeds the sum of such projections of undiscounted cash flows. The Company accounts for the present value of the future profits embedded in Property and Casualty Insurance Broker Relationships Acquired (“P&C Broker Relationships”) based on the present value of estimated future cash flows from the broker relationships acquired. P&C Broker Relationships was $16.8 million and $18.1 million at December 31, 2016 and 2015 , respectively. P&C Broker Relationships is amortized on a straight-line basis over 15 years . P&C Broker Relationships is tested for recoverability using undiscounted projections of future cash flows and written down to estimated fair value if the carrying value exceeds the sum of such projections of undiscounted cash flows.
Accrued Expenses and Other Liabilities	Accrued Expenses and Other Liabilities Accrued Expenses and Other Liabilities primarily include accrued salaries and commissions, pension benefits, postretirement medical benefits and accrued taxes, licenses and fees.
Recognition of Earned Premiums and Related Expenses	Recognition of Earned Premiums and Related Expenses Property and casualty insurance and short duration health insurance premiums are deferred when written and recognized and earned ratably over the periods to which the premiums relate. Unearned Premiums represent the portion of the premiums written related to the unexpired portion of policies in force which has been deferred and is reported as a liability. The Company performs a premium deficiency analysis typically at a product line level, namely automobile insurance, homeowners insurance and other insurance, which is consistent with the manner in which the Company acquires and services policies and measures profitability. Anticipated investment income is excluded from such analysis. A premium deficiency is recognized when the sum of expected claim costs, claim adjustment expenses, unamortized deferred policy acquisition costs and maintenance costs exceeds the related unearned premiums by first reducing related deferred policy acquisition costs to an amount, but not below zero, at which the premium deficiency would not exist. If a premium deficiency remains after first reducing deferred policy acquisition costs, a premium deficiency reserve is established and reported as a liability in the Company’s financial statements. The Company’s deferred policy acquisition costs in the Consolidated Balance Sheets at December 31, 2016 and 2015 include reductions of $9.7 million and $9.0 million , respectively, due to premium deficiencies with respect to Alliance United’s personal automobile book of business. Traditional life insurance premiums are recognized as revenue when due. Policyholders’ benefits are associated with related premiums to result in recognition of profits over the periods for which the benefits are provided using the net level premium method. Policyholders’ Benefits and Incurred Losses and Loss Adjustment Expenses include provisions for future policy benefits under life and certain accident and health insurance contracts and provisions for reported claims, estimates for IBNR claims and loss adjustment expenses. Benefit payments in excess of policy account balances are expensed.
Reinsurance	Reinsurance In the normal course of business, Kemper’s insurance subsidiaries reinsure certain risks above certain retention levels with other insurance enterprises. These reinsurance agreements do not relieve Kemper’s insurance subsidiaries of their legal obligations to the policyholder. Amounts recoverable from reinsurers are included in Other Receivables. NOTE 2. SUMMARY OF ACCOUNTING POLICIES AND ACCOUNTING CHANGES (Continued) Gains related to long-duration reinsurance contracts are deferred and amortized over the life of the underlying reinsured policies. Losses related to long-duration reinsurance contracts are recognized immediately. Any gain or loss associated with reinsurance agreements for which Kemper’s insurance subsidiaries have been legally relieved of their obligations to the policyholder is recognized in the period of relief.
Income Taxes	Income Taxes Deferred income tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. A valuation allowance, if any, is maintained for the portion of deferred income tax assets that the Company does not expect to recover. Increases, if any, in the valuation allowance for deferred income tax assets are recognized as income tax expense. Decreases, if any, in the valuation allowance for deferred income tax assets are recognized as income tax benefit. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in income in the period in which the change is enacted. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken, or expected to be taken, in an income tax return. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.
