Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Estimates	BASIS OF PRESENTATION AND SIGNIFICANT ESTIMATES The Consolidated Financial Statements include the accounts of Kemper Corporation (“Kemper”) and its subsidiaries which include property and casualty, life subsidiaries and a health subsidiary through the date of its sale of December 1, 2022 (collectively referred to herein as the “Company”). The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). All intercompany accounts and transactions have been eliminated. Periodically, Kemper may acquire an additional company which then becomes one of the various subsidiaries of Kemper. When an acquisition occurs, Kemper will include the results of the acquired company in the consolidated financial results from the date of its acquisition and forward. When a disposition occurs, Kemper will include the results of the disposed subsidiary in the consolidated financial results prior to the date of sale. In 2021, the Company elected to begin displaying its investments in Alternative Energy Partnerships in the Consolidated Statements of (Loss) Income and Consolidated Balance Sheets as Change in Value of Alternative Energy Partnership Investments and Alternative Energy Partnership Investments, respectively. These were previously reported in Equity Method Limited Liability Investments on the Consolidated Balance Sheets. Impacts to prior period presentation are not material. 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. Many of these estimates and assumptions are common in the insurance and financial services industries; others are specific to the Company’s business and operations. Actual results could differ materially from those estimates and assumptions. The fair values of the Company’s Investments in Fixed Maturities, Investments in Convertible Securities at Fair Value, Investments in Equity Securities at Fair Value 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 Company’s portfolio also includes investments in Alternative Energy Partnerships that are accounted for under the Hypothetical Liquidation at Book Value (“HLBV”) method. Under the HLBV method, the amounts of income and loss attributed to investors reflect changes in the amounts the fund investors would hypothetically receive at each balance sheet date under the liquidation provisions of the contractual agreements of these funds. Attributing income and loss under the HLBV method requires the use of significant assumptions and forecasts to calculate the amounts that fund investors would receive upon a hypothetical liquidation. 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 differing 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 and operating results may differ materially from those projected. As a result, the Company’s assessment of the impairment of long-lived assets and recoverability of deferred tax assets is susceptible to the risk inherent in making such projections.
