Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements of Horace Mann Educators Corporation (HMEC; and together with its subsidiaries, the Company or Horace Mann) have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) and with the rules and regulations of the Securities and Exchange Commission (SEC), specifically Regulation S-X and the instructions to Form 10-Q. Certain information and disclosures normally included in annual financial statements prepared in conformity with GAAP, but are not required for interim reporting purposes, have been omitted. The Company believes that these consolidated financial statements contain all adjustments (consisting of normal recurring accruals) which are, in the opinion of management, necessary to present fairly the Company’s consolidated financial position as of September 30, 2018 , the consolidated results of operations and comprehensive income (loss) for the three and nine month periods ended September 30, 2018 and 2017 and the consolidated changes in shareholders’ equity and cash flows for the nine month periods ended September 30, 2018 and 2017 . The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The subsidiaries of HMEC market and underwrite personal lines of property and casualty insurance products (primarily personal lines of automobile and property insurance), retirement products (primarily tax-qualified annuities) and life insurance, primarily to K-12 teachers, administrators and other employees of public schools and their families. HMEC’s principal operating subsidiaries are Horace Mann Life Insurance Company, Horace Mann Insurance Company, Teachers Insurance Company, Horace Mann Property & Casualty Insurance Company and Horace Mann Lloyds. These consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes to consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 . The results of operations for the three and nine month period ended September 30, 2018 are not necessarily indicative of the results to be expected for the full year. The Company has reclassified the presentation of certain prior period information to conform to the current presentation. Investment Contract and Life Policy Reserves This table summarizes the Company’s investment contract and life policy reserves. ($ in thousands) September 30, 2018 December 31, 2017 Investment contract reserves $ 4,545,232 $ 4,452,972 Life policy reserves 1,145,457 1,120,763 Total $ 5,690,689 $ 5,573,735 Accumulated Other Comprehensive Income (Loss) Accumulated other comprehensive income (loss) (AOCI) represents the accumulated change in shareholders’ equity from transactions and other events and circumstances from non-shareholder sources. For the Company, AOCI includes the after tax change in net unrealized investment gains (losses) on securities and the after tax change in net funded status of benefit plans for the periods as shown in the Consolidated Statements of Changes in Shareholders’ Equity. The following tables reconcile these components. ($ in thousands) Net Unrealized Investment Gains (Losses) on Securities (1)(2) Net Funded Status of Benefit Plans (1) Total (1) Beginning balance, July 1, 2018 $ 125,596 $ (13,217 ) $ 112,379 Other comprehensive income (loss) before reclassifications (49,165 ) — (49,165 ) Amounts reclassified from accumulated other comprehensive income (loss) (473 ) — (473 ) Cumulative effect of change in accounting principle — — — Net current period other comprehensive income (loss) (49,638 ) — (49,638 ) Ending balance, September 30, 2018 $ 75,958 $ (13,217 ) $ 62,741 Beginning balance, January 1, 2018 $ 300,177 $ (13,217 ) $ 286,960 Other comprehensive income (loss) before reclassifications (211,577 ) — (211,577 ) Amounts reclassified from accumulated other comprehensive income (loss) 2,399 — 2,399 Cumulative effect of change in accounting principle (3) (15,041 ) — (15,041 ) Net current period other comprehensive income (loss) (224,219 ) — (224,219 ) Ending balance, September 30, 2018 $ 75,958 $ (13,217 ) $ 62,741 ________________ (1) All amounts are net of tax. (2) The pretax amounts reclassified from AOCI, $599 thousand and $(3,037) thousand , are included in Net investment gains (losses) and the related income tax expenses, $126 thousand and $(638) thousand , are included in Income tax expense in the Consolidated Statements of Operations for the three and nine month periods ended September 30, 2018 , respectively. (3) The Company adopted guidance on January 1, 2018 that resulted in reclassifying $15,041 thousand of after tax net unrealized gains on equity securities from AOCI to Retained earnings. ($ in thousands) Net Unrealized Investment Gains (Losses) on Securities (1)(2) Net Funded Status of Benefit Plans (1) Total (1) Beginning balance, July 1, 2017 $ 243,510 $ (11,817 ) $ 231,693 Other comprehensive income (loss) before reclassifications 9,786 — 9,786 Amounts reclassified from accumulated other comprehensive income (loss) 2,422 — 2,422 Net current period other comprehensive income (loss) 12,208 — 12,208 Ending balance, September 30, 2017 $ 255,718 $ (11,817 ) $ 243,901 Beginning balance, January 1, 2017 $ 175,738 $ (11,817 ) $ 163,921 Other comprehensive income (loss) before reclassifications 78,419 — 78,419 Amounts reclassified from accumulated other comprehensive income (loss) 1,561 — 1,561 Net current period other comprehensive income (loss) 79,980 — 79,980 Ending balance, September 30, 2017 $ 255,718 $ (11,817 ) $ 243,901 ________________ (1) All amounts are net of tax. (2) The pretax amounts reclassified from AOCI, $(3,726) thousand and $(2,401) thousand , are included in Net investment gains (losses) and the related income tax expenses, $(1,304) thousand and $(840) thousand , are included in Income tax expense in the Consolidated Statements of Operations for the three and nine month periods ended September 30, 2017 , respectively. Comparative information for elements that are not required to be reclassified in their entirety to Net income in the same reporting period is located in Note 2 -- Investments -- Net Unrealized Investment Gains (Losses) on Securities. Adopted Accounting Standards Revenue Recognition In May 2014, the Financial Accounting Standards Board (FASB) issued accounting guidance, with an effective date that was deferred to January 1, 2018, to provide a single comprehensive model in accounting for revenue arising from contracts with customers. The guidance applies to all contracts with customers; however, certain insurance contracts are specifically excluded from this updated guidance. The Company adopted the guidance on January 1, 2018, using the modified retrospective transition method. The guidance did not have an impact on the Company’s consolidated financial position, results of operations, cash flows, or disclosures. Recognition and Measurement of Financial Assets and Liabilities In January 2016, the FASB issued accounting guidance to improve certain aspects of the recognition, measurement, presentation and disclosure of financial instruments. Among other things, the guidance revises the accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. The Company adopted the guidance on January 1, 2018 using the modified retrospective approach that resulted in reclassifying $15,041 thousand of after tax net unrealized gains on equity securities from AOCI to Retained earnings. The Company's Consolidated Statements of Operations were impacted as changes in fair value of equity securities are now being reported in Net investment gains (losses) instead of reported in other comprehensive income (loss) (OCI). Statement of Cash Flows -- Classification In August 2016, the FASB issued guidance to reduce diversity in practice in the statement of cash flows between operating, investing and financing activities related to the classification of cash receipts and cash payments for eight specific issues. The FASB acknowledged that current GAAP either is unclear or does not include specific guidance on these eight cash flow classification issues: (1) debt prepayment or extinguishment costs; (2) settlement of zero-coupon bonds (pertains to issuers); (3) contingent consideration payments made after a business combination; (4) proceeds from the settlement of insurance claims (pertains to claimants); (5) proceeds from the settlement of corporate-owned life insurance policies; (6) distributions received from equity method investees; (7) beneficial interests in securitization transactions (pertains to transferors) and (8) separately identifiable cash flows and application of the predominance principle. The Company adopted the guidance on January 1, 2018 using a retrospective approach which had no impact to the prior year amounts reported in the Consolidated Statement of Cash Flows. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Loss) On February 14, 2018, the FASB issued accounting guidance that permits recognition of a reclassification adjustment between AOCI and Retained earnings for stranded tax amounts related to the reduced corporate tax rate enacted under the Tax Act. As permitted under its provisions, the Company early adopted the accounting guidance effective for the quarterly period that ended December 31, 2017 and elected to reclassify the stranded tax amounts. The impact from early adoption resulted in an increase to AOCI and a reduction to Retained earnings of approximately $47,900 thousand ; representing the stranded deferred tax liabilities of $50,034 thousand and $(2,134) thousand for Net unrealized investment gains (losses) on securities and Net funded status of benefit plans, respectively. Pending Accounting Standards Accounting for Leases In February 2016, the FASB issued accounting and disclosure guidance to improve financial reporting and comparability among organizations about leasing transactions. Under the new guidance, for leases with lease terms of more than 12 months, a lessee will be required to recognize assets and liabilities on the balance sheet for the rights and obligations created by those leases. Consistent with current accounting guidance, the recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or an operating lease. However, while current guidance requires only capital leases to be recognized on the balance sheet, the new guidance will require both operating and capital leases to be recognized on the balance sheet. This new guidance is effective for annual reporting periods beginning December 15, 2018, and interim reporting periods within those annual periods, with early adoption permitted. The Company will adopt this new guidance on January 1, 2019, and the Company expects to use the optional transition method, which allows the Company to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption (i.e., comparative periods presented in the consolidated financial statements will continue to be in conformity with current GAAP). While the Company is in the process of evaluating the impact of the guidance, it does not expect the guidance to have a material impact on its consolidated financial statements. Had the Company adopted the guidance on September 30, 2018 , it would have recognized additional operating liabilities of $13,267 thousand , with corresponding right of use assets of the same amount based on the present value of the expected remaining lease payments under the new guidance. Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued guidance to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments, including reinsurance receivables, held by companies. The new guidance replaces the incurred loss impairment methodology and requires an organization to measure and recognize all current expected credit losses (CECL) for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Companies will need to utilize forward-looking information to better inform their credit loss estimates. Companies will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. Any credit losses related to available for sale debt securities will be recorded through an allowance for credit losses with this allowance having a limit equal to the amount by which fair value is below amortized cost. The guidance also requires enhanced qualitative and quantitative disclosures to provide additional information about the amounts recorded in the financial statements. For public business entities, the guidance is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those years, using a modified-retrospective approach. Early application is permitted for annual reporting periods, and interim periods within those years, beginning after December 15, 2018. Management is evaluating the impact this guidance will have on the results of operations and financial position of the Company. Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued guidance to simplify the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. Entities will be required to disclose the amount of goodwill for reporting units with zero or negative carrying amounts. Public business entities should adopt the guidance prospectively for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early application is permitted. Management believes the adoption of this accounting guidance will not have a material effect on the results of operations and financial position of the Company.

Investments, Debt and Equity Securities [Abstract]
Investments	The Company’s investment portfolio includes free-standing derivative financial instruments (currently over the counter index call option contracts) to economically hedge risk associated with its fixed indexed annuity (FIA) and indexed universal life (IUL) products’ contingent liabilities. The Company’s FIA and IUL products include embedded derivative features that are discussed in Note 1 -- Summary of Significant Accounting Policies -- Investment Contract and Life Policy Reserves -- Reserves for Fixed Indexed Annuities and Indexed Universal Life Policies of the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 . The Company’s investment portfolio included no other free-standing derivative financial instruments (futures, forwards, swaps, option contracts or other financial instruments with similar characteristics), and there were no other embedded derivative features related to the Company’s investment or insurance products during the nine month periods ended September 30, 2018 and 2017 . Fixed Maturity Securities The Company’s investment portfolio is comprised primarily of fixed maturity securities. The amortized cost, net unrealized investment gains (losses) and fair values of all fixed maturity securities in the portfolio were as follows: ($ in thousands) Amortized Cost/Cost Unrealized Investment Gains Unrealized Investment Losses Fair Value September 30, 2018 (1) Fixed maturity securities U.S. Government and federally sponsored agency obligations: (2) Mortgage-backed securities $ 758,301 $ 15,744 $ 23,209 $ 750,836 Other, including U.S. Treasury securities 802,508 12,528 32,436 782,600 Municipal bonds 1,783,711 119,671 19,708 1,883,674 Foreign government bonds 92,860 2,787 644 95,003 Corporate bonds 2,290,452 74,409 29,365 2,335,496 Other mortgage-backed securities 1,691,659 8,073 18,202 1,681,530 Totals $ 7,419,491 $ 233,212 $ 123,564 $ 7,529,139 December 31, 2017 Fixed maturity securities U.S. Government and federally sponsored agency obligations: (2) Mortgage-backed securities $ 669,297 $ 30,460 $ 3,032 $ 696,725 Other, including U.S. Treasury securities 714,613 26,311 5,516 735,408 Municipal bonds 1,711,581 184,107 2,435 1,893,253 Foreign government bonds 96,780 5,958 — 102,738 Corporate bonds 2,409,426 173,862 4,334 2,578,954 Other mortgage-backed securities 1,701,253 22,935 7,191 1,716,997 Totals $ 7,302,950 $ 443,633 $ 22,508 $ 7,724,075 Equity securities (3) $ 116,320 $ 19,425 $ 279 $ 135,466 ________________ (1) Effective January 1, 2018, with the adoption of new accounting guidance for recognition and measurement of financial instruments, available for sale equity securities were reclassified to equity securities at fair value and are excluded from the table above as of September 30, 2018. (2) Fair value includes securities issued by Federal National Mortgage Association (FNMA) of $408,130 thousand and $361,955 thousand ; Federal Home Loan Mortgage Corporation (FHLMC) of $408,858 thousand and $400,001 thousand ; and Government National Mortgage Association (GNMA) of $96,018 thousand and $104,168 thousand as of September 30, 2018 and December 31, 2017 , respectively. (3) Includes nonredeemable (perpetual) preferred stocks, common stocks and closed-end funds. The following table presents the fair value and gross unrealized losses of securities in an unrealized loss position at September 30, 2018 and December 31, 2017 , respectively. The Company views the decrease in value of all of the securities with unrealized losses at September 30, 2018 -- which was driven largely by increasing interest rates, spread widening, financial market illiquidity and/or market volatility from the date of acquisition -- as temporary. For fixed maturity securities, management does not have the intent to sell the securities and it is not more likely than not the Company will be required to sell the securities before the anticipated recovery of their amortized cost bases, and management expects to recover the entire amortized cost bases of the fixed maturity securities. Therefore, it was determined that the unrealized losses on the securities presented in the table below were not other than temporarily impaired as of September 30, 2018 .

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	The Company is required under GAAP to disclose estimated fair values for certain financial and nonfinancial assets and liabilities. Fair values of the Company’s insurance contracts other than annuity contracts are not required to be disclosed. However, the estimated fair values of liabilities under all insurance contracts are taken into consideration in the Company’s overall management of interest rate risk through the matching of investment maturities with amounts due under insurance contracts. Information regarding the three-level hierarchy presented below and the valuation methodologies utilized by the Company to estimate fair values at each reporting date is included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 , specifically in Note 3 -- Fair Value of Financial Instruments. Financial Instruments Measured and Carried at Fair Value The following table presents the Company’s fair value hierarchy for those assets and liabilities measured and carried at fair value on a recurring basis. At September 30, 2018 , Level 3 invested assets comprised 3.2% of the Company’s total investment portfolio at fair value.

(3) Transfers into and out of Level 3 during the three and nine month periods ended September 30, 2017 were attributable to changes in the availability of observable market information for individual fixed maturity securities and short-term investments. The Company’s policy is to recognize transfers into and transfers out of the levels as having occurred at the end of the reporting period in which the transfers were determined. For the nine month period ended September 30, 2018 , the Company realized a net loss of $243 thousand on three Level 3 securities. For the nine month period ended September 30, 2017 , the Company impaired two Level 3 securities for a $1,875 thousand realized loss. For the three and nine month periods ended September 30, 2018 , net investment losses of $2,205 thousand and gains of $1,308 thousand , respectively, were included in earnings that were attributable to the changes in the fair value of Level 3 liabilities (embedded derivatives) still held; for the three and nine month periods ended September 30, 2017 , the respective loss amounts were $2,587 thousand and $6,133 thousand . The valuation techniques and significant unobservable inputs used in the fair value measurement for financial assets and liabilities classified as Level 3 are subject to the control processes as described in Note 3 -- Fair Value of Financial Instruments -- Investments in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 . Generally, valuation techniques for fixed maturity securities include spread pricing, matrix pricing and discounted cash flow methodologies; include inputs such as quoted prices for identical or similar securities that are less liquid; and are based on lower levels of trading activity than securities classified as Level 2. The valuation techniques and significant unobservable inputs used in the fair value measurement for equity securities classified as Level 3 use similar valuation techniques and significant unobservable inputs as those used for fixed maturity securities. The sensitivity of the estimated fair values to changes in the significant unobservable inputs for fixed maturity and equity securities included in Level 3 generally relate to interest rate spreads, illiquidity premiums and default rates. Significant spread widening in isolation will adversely impact the overall valuation, while significant spread tightening will lead to substantial valuation increases. Significant increases (decreases) in illiquidity premiums in isolation will result in substantially lower (higher) valuations. Significant increases (decreases) in expected default rates in isolation will result in substantially lower (higher) valuations. Financial Instruments Not Carried at Fair Value; Disclosure Required The Company has various other financial assets and financial liabilities used in the normal course of business that are not carried at fair value, but for which fair value disclosure is required. The following table presents the carrying value, fair value and fair value hierarchy of these financial assets and financial liabilities.

Derivative Instruments

Derivative Instruments	9 Months Ended
	Sep. 30, 2018
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	The Company offers FIA products, which are deferred fixed annuities that guarantee the return of principal to the contractholder and credit interest based on a percentage of the gain in a specified market index. The Company also offers IUL products which credit interest based on a percentage of the gain in a specified market index. When deposits are received for FIA and IUL contracts, a portion is used to purchase derivatives consisting of call options on the applicable market indices to fund the index credits due to FIA and IUL policyholders. For the Company, substantially all of such call options are one-year options purchased to match the funding requirements of the underlying contracts. The call options are carried at fair value with changes in fair value included in Net investment gains (losses), a component of Revenues, in the Consolidated Statements of Operations. The change in fair value of derivatives includes the gains or losses recognized at the expiration of the option term or early termination and the changes in fair value for open positions. Call options are not purchased to fund the index liabilities which may arise after the next deposit anniversary date. On the respective anniversary dates of the indexed deposits, the index used to compute the annual index credit is reset and new one-year call options are purchased to fund the next annual index credit. The cost of these purchases is managed through the terms of the FIA and IUL contracts, which permit changes to index return caps, participation rates and/or asset fees, subject to guaranteed minimums on each contract’s anniversary date. By adjusting the index return caps, participation rates or asset fees, crediting rates generally can be managed except in cases where the contractual features would prevent further modifications. The future annual index credits on FIA contracts are treated as a "series of embedded derivatives" over the expected life of the applicable contract with a corresponding reserve recorded. For IUL, the embedded derivative represents a single year liability for the index return. The Company carries all derivative instruments at fair value in the Consolidated Balance Sheets. The Company elected to not use hedge accounting for derivative transactions related to the FIA and IUL products. As a result, the Company recognizes the purchased call options and the embedded derivatives related to the provision of a contingent return at fair value, with changes in the fair value of the derivatives recognized immediately as Net investment gains (losses) in the Consolidated Statements of Operations. The fair values of derivative instruments, including derivative instruments embedded in FIA and IUL contracts, are presented in the Consolidated Balance Sheets as follows: ($ in thousands) September 30, 2018 December 31, 2017 Assets Derivative instruments, included in Short-term and other investments $ 10,198 $ 15,550 Liabilities FIA - embedded derivatives, included in Other policyholder funds $ 82,265 $ 80,733 IUL - embedded derivatives, included in Investment contract and life policy reserves 722 594 In general, the change in the fair value of the embedded derivatives related to FIA contracts will not correspond to the change in fair value of the purchased call options because the purchased call options are one-year options while the options valued in the embedded derivatives represent the rights of the policyholder to receive index credits over the entire period the FIA contracts are expected to be in force, which typically exceeds 10 years. The changes in fair value of derivatives included in the Consolidated Statements of Operations were as follows: ($ in thousands) Three Months Ended Nine Months Ended 2018 2017 2018 2017 Change in fair value of derivatives: (1) Revenues Net investment gains (losses) $ 4,683 $ 2,943 $ 3,832 $ 7,109 Change in fair value of embedded derivatives: Revenues Net investment gains (losses) $ (2,479 ) $ (2,702 ) $ 1,090 $ (6,363 ) ________________ (1) Includes the gains or losses recognized at the expiration of the option term or early termination and the changes in fair value for open options. The Company’s strategy attempts to mitigate potential risk of loss under these agreements through a regular monitoring process, which evaluates the program’s effectiveness. The Company is exposed to risk of loss in the event of nonperformance by the counterparties and, accordingly, option contracts are purchased from multiple counterparties, which are evaluated for creditworthiness prior to purchase of the contracts. All of these options have been purchased from nationally recognized financial institutions with a Standard and Poor’s Financial Services LLC (S&P) and/or Moody's Investors Service (Moody's) long-term credit rating of "BBB+/Bbb1" or higher at the time of purchase and the maximum credit exposure to any single counterparty is subject to concentration limits. The Company also obtains credit support agreements that allow it to request the counterparty to provide collateral when the fair value of the exposure to the counterparty exceeds specified amounts. The notional amount and fair value of call options by counterparty and each counterparty’s long-term credit ratings were as follows: ($ in thousands) September 30, 2018 December 31, 2017 Credit Rating Notional Fair Notional Fair Counterparty S&P Moody's Amount Value Amount Value Bank of America, N.A.

This derivative collateral limits the Company’s maximum amount of economic loss due to credit risk that would be incurred if parties to the call options failed completely to perform according to the terms of the contracts to $250 thousand

Segment Information	The Company conducts and manages its business through four segments. The three operating segments, representing the major lines of insurance business, are: Property and Casualty, primarily personal lines automobile and property insurance products; Retirement, primarily tax-qualified fixed and variable annuities; and Life, life insurance. The Company does not allocate the impact of corporate-level transactions to these operating segments, consistent with the basis for management’s evaluation of the results of those segments, but classifies those items in the fourth segment, Corporate and Other. In addition to ongoing transactions such as corporate debt service, net investment gains (losses) certain public company expenses, such items also have included corporate debt retirement costs, when applicable.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements of Horace Mann Educators Corporation (HMEC; and together with its subsidiaries, the Company or Horace Mann) have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) and with the rules and regulations of the Securities and Exchange Commission (SEC), specifically Regulation S-X and the instructions to Form 10-Q. Certain information and disclosures normally included in annual financial statements prepared in conformity with GAAP, but are not required for interim reporting purposes, have been omitted. The Company believes that these consolidated financial statements contain all adjustments (consisting of normal recurring accruals) which are, in the opinion of management, necessary to present fairly the Company’s consolidated financial position as of September 30, 2018 , the consolidated results of operations and comprehensive income (loss) for the three and nine month periods ended September 30, 2018 and 2017 and the consolidated changes in shareholders’ equity and cash flows for the nine month periods ended September 30, 2018 and 2017 . The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The subsidiaries of HMEC market and underwrite personal lines of property and casualty insurance products (primarily personal lines of automobile and property insurance), retirement products (primarily tax-qualified annuities) and life insurance, primarily to K-12 teachers, administrators and other employees of public schools and their families. HMEC’s principal operating subsidiaries are Horace Mann Life Insurance Company, Horace Mann Insurance Company, Teachers Insurance Company, Horace Mann Property & Casualty Insurance Company and Horace Mann Lloyds. These consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes to consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 . The results of operations for the three and nine month period ended September 30, 2018 are not necessarily indicative of the results to be expected for the full year. The Company has reclassified the presentation of certain prior period information to conform to the current presentation.
Accumulated Other Comprehensive Income (Loss)	Comparative information for elements that are not required to be reclassified in their entirety to Net income in the same reporting period is located in Note 2 -- Investments -- Net Unrealized Investment Gains (Losses) on Securities.Accumulated Other Comprehensive Income (Loss)
Adopted and Pending Accounting Standards	Adopted Accounting Standards Revenue Recognition In May 2014, the Financial Accounting Standards Board (FASB) issued accounting guidance, with an effective date that was deferred to January 1, 2018, to provide a single comprehensive model in accounting for revenue arising from contracts with customers. The guidance applies to all contracts with customers; however, certain insurance contracts are specifically excluded from this updated guidance. The Company adopted the guidance on January 1, 2018, using the modified retrospective transition method. The guidance did not have an impact on the Company’s consolidated financial position, results of operations, cash flows, or disclosures. Recognition and Measurement of Financial Assets and Liabilities In January 2016, the FASB issued accounting guidance to improve certain aspects of the recognition, measurement, presentation and disclosure of financial instruments. Among other things, the guidance revises the accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. The Company adopted the guidance on January 1, 2018 using the modified retrospective approach that resulted in reclassifying $15,041 thousand of after tax net unrealized gains on equity securities from AOCI to Retained earnings. The Company's Consolidated Statements of Operations were impacted as changes in fair value of equity securities are now being reported in Net investment gains (losses) instead of reported in other comprehensive income (loss) (OCI). Statement of Cash Flows -- Classification In August 2016, the FASB issued guidance to reduce diversity in practice in the statement of cash flows between operating, investing and financing activities related to the classification of cash receipts and cash payments for eight specific issues. The FASB acknowledged that current GAAP either is unclear or does not include specific guidance on these eight cash flow classification issues: (1) debt prepayment or extinguishment costs; (2) settlement of zero-coupon bonds (pertains to issuers); (3) contingent consideration payments made after a business combination; (4) proceeds from the settlement of insurance claims (pertains to claimants); (5) proceeds from the settlement of corporate-owned life insurance policies; (6) distributions received from equity method investees; (7) beneficial interests in securitization transactions (pertains to transferors) and (8) separately identifiable cash flows and application of the predominance principle. The Company adopted the guidance on January 1, 2018 using a retrospective approach which had no impact to the prior year amounts reported in the Consolidated Statement of Cash Flows. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Loss) On February 14, 2018, the FASB issued accounting guidance that permits recognition of a reclassification adjustment between AOCI and Retained earnings for stranded tax amounts related to the reduced corporate tax rate enacted under the Tax Act. As permitted under its provisions, the Company early adopted the accounting guidance effective for the quarterly period that ended December 31, 2017 and elected to reclassify the stranded tax amounts. The impact from early adoption resulted in an increase to AOCI and a reduction to Retained earnings of approximately $47,900 thousand ; representing the stranded deferred tax liabilities of $50,034 thousand and $(2,134) thousand for Net unrealized investment gains (losses) on securities and Net funded status of benefit plans, respectively. Pending Accounting Standards Accounting for Leases In February 2016, the FASB issued accounting and disclosure guidance to improve financial reporting and comparability among organizations about leasing transactions. Under the new guidance, for leases with lease terms of more than 12 months, a lessee will be required to recognize assets and liabilities on the balance sheet for the rights and obligations created by those leases. Consistent with current accounting guidance, the recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or an operating lease. However, while current guidance requires only capital leases to be recognized on the balance sheet, the new guidance will require both operating and capital leases to be recognized on the balance sheet. This new guidance is effective for annual reporting periods beginning December 15, 2018, and interim reporting periods within those annual periods, with early adoption permitted. The Company will adopt this new guidance on January 1, 2019, and the Company expects to use the optional transition method, which allows the Company to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption (i.e., comparative periods presented in the consolidated financial statements will continue to be in conformity with current GAAP). While the Company is in the process of evaluating the impact of the guidance, it does not expect the guidance to have a material impact on its consolidated financial statements. Had the Company adopted the guidance on September 30, 2018 , it would have recognized additional operating liabilities of $13,267 thousand , with corresponding right of use assets of the same amount based on the present value of the expected remaining lease payments under the new guidance. Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued guidance to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments, including reinsurance receivables, held by companies. The new guidance replaces the incurred loss impairment methodology and requires an organization to measure and recognize all current expected credit losses (CECL) for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Companies will need to utilize forward-looking information to better inform their credit loss estimates. Companies will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. Any credit losses related to available for sale debt securities will be recorded through an allowance for credit losses with this allowance having a limit equal to the amount by which fair value is below amortized cost. The guidance also requires enhanced qualitative and quantitative disclosures to provide additional information about the amounts recorded in the financial statements. For public business entities, the guidance is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those years, using a modified-retrospective approach. Early application is permitted for annual reporting periods, and interim periods within those years, beginning after December 15, 2018. Management is evaluating the impact this guidance will have on the results of operations and financial position of the Company. Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued guidance to simplify the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. Entities will be required to disclose the amount of goodwill for reporting units with zero or negative carrying amounts. Public business entities should adopt the guidance prospectively for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early application is permitted. Management believes the adoption of this accounting guidance will not have a material effect on the results of operations and financial position of the Company.

Summary of fair value and gross unrealized losses of fixed maturity securities and equity securities in an unrealized loss position	The following table presents the fair value and gross unrealized losses of securities in an unrealized loss position at September 30, 2018 and December 31, 2017 , respectively. The Company views the decrease in value of all of the securities with unrealized losses at September 30, 2018 -- which was driven largely by increasing interest rates, spread widening, financial market illiquidity and/or market volatility from the date of acquisition -- as temporary. For fixed maturity securities, management does not have the intent to sell the securities and it is not more likely than not the Company will be required to sell the securities before the anticipated recovery of their amortized cost bases, and management expects to recover the entire amortized cost bases of the fixed maturity securities. Therefore, it was determined that the unrealized losses on the securities presented in the table below were not other than temporarily impaired as of September 30, 2018 .
