Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Basis of Presentation	NATURE OF OPERATIONS AND BASIS OF PRESENTATION Nature of Business United Fire Group, Inc. ("UFG," the "Registrant," the "Company," "we," "us," or "our") and its consolidated subsidiaries and affiliates are engaged in the business of writing property and casualty insurance and life insurance and selling annuities through a network of independent agencies. Our insurance company subsidiaries are licensed as a property and casualty insurer in 46 states and the District of Columbia, and as a life insurer in 37 states. Discontinued Operations We have historically reported our operations in two business segments: property and casualty insurance and life insurance. On September 18, 2017, the Company signed a definitive agreement to sell its subsidiary, United Life Insurance Company, to Kuvare US Holdings, Inc. ("Kuvare"). As a result, our life insurance business, previously a separate segment, has been considered held for sale and reported as discontinued operations in the Consolidated Balance Sheets, Consolidated Statements of Income and Comprehensive Income and Consolidated Statements of Cash Flows (collectively, the "Consolidated Financial Statements"). Subsequent to the announcement of this sale, our continuing operations are now reported as one business segment. All current and prior periods reflected in this Form 10-Q have been presented as continuing and discontinued operations, unless otherwise noted. The sale is expected to close in the first half of 2018, subject to customary conditions, including regulatory approval. For more information, refer to Note 11. Discontinued Operations. Basis of Presentation The unaudited consolidated interim financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial reporting and with the instructions to Form 10-Q and Regulation S-X promulgated by the SEC. Certain financial information that is included in our Annual Report on Form 10-K, including certain financial statement footnote disclosures, are not required by the rules and regulations of the SEC for interim financial reporting and have been condensed or omitted. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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 from those estimates. The financial statement categories that are most dependent on management estimates and assumptions include: investments; deferred policy acquisition costs; reinsurance receivables and recoverables; future policy benefits and losses, claims and loss settlement expenses; and pension and postretirement benefit obligations. Certain prior year amounts have been reclassified to conform to the current year presentation. Management of UFG believes the accompanying unaudited Consolidated Financial Statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the periods presented. All significant intercompany transactions have been eliminated in consolidation. The results reported for the interim periods are not necessarily indicative of the results of operations that may be expected for the year. The unaudited Consolidated Financial Statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2016 . The review report of Ernst & Young LLP as of September 30, 2017 and for the three- and nine-month periods ended September 30, 2017 and 2016 accompanies the unaudited Consolidated Financial Statements included in Part I, Item 1 "Financial Statements." Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash, money market accounts, and non-negotiable certificates of deposit with original maturities of three months or less. For the nine-month periods ended September 30, 2017 and 2016 , we made payments for income taxes for continuing operations totaling $7,648 and $24,026 , respectively. We received a tax refund of $10,000 during the nine-month period ended September 30, 2017 . We did no t receive a tax refund during the nine-month period ended September 30, 2016 . For the nine-month periods ended September 30, 2017 and 2016 , we made no interest payments (excluding interest credited to policyholders’ accounts). Deferred Policy Acquisition Costs ("DAC") Certain costs associated with underwriting new business (primarily commissions, premium taxes and variable underwriting and policy issue expenses associated with successful acquisition efforts) are deferred. The following table is a summary of the components of DAC, including the related amortization recognized for the nine-month period ended September 30, 2017 . Continuing Operations Discontinued Operations Property & Casualty Insurance Life Insurance Total Recorded asset at beginning of period $ 93,362 $ 70,750 $ 164,112 Underwriting costs deferred 158,960 4,192 163,152 Amortization of deferred policy acquisition costs (154,845 ) (5,524 ) (160,369 ) Ending unamortized deferred policy acquisition costs $ 97,477 $ 69,418 $ 166,895 Impact of unrealized gains and losses on available-for-sale securities — (3,582 ) (3,582 ) Recorded asset at September 30, 2017 $ 97,477 $ 65,836 $ 163,313 Property and casualty insurance policy acquisition costs deferred are amortized as premium revenue is recognized. The method followed in computing DAC limits the amount of such deferred costs to their estimated realizable value. This takes into account the premium to be earned, losses and loss settlement expenses expected to be incurred and certain other costs expected to be incurred as the premium is earned. For traditional life insurance policies, DAC is amortized to income over the premium-paying period in proportion to the ratio of the expected annual premium revenue to the expected total premium revenue. Expected premium revenue and gross profits are based on the same mortality and withdrawal assumptions used in determining future policy benefits. These assumptions are not revised after policy issuance unless the recorded DAC asset is deemed to be unrecoverable from future expected profits. For non-traditional life insurance policies, DAC is amortized over the anticipated terms in proportion to the ratio of the expected annual gross profits to the total expected gross profits. Changes in the amount or timing of expected gross profits result in adjustments to the cumulative amortization of these costs. The effect on amortization of DAC for revisions to estimated gross profits is reported in earnings in the period the estimated gross profits are revised. The effect on DAC that results from the assumed realization of unrealized gains (losses) on investments allocated to non-traditional life insurance business is recognized with an offset to net unrealized investment appreciation as of the balance sheet date. The impact of unrealized gains and losses on available-for-sale securities decreased the DAC asset by $9,995 and $6,413 at September 30, 2017 and December 31, 2016 , respectively. Income Taxes Deferred tax assets and liabilities are established based on differences between the financial statement bases of assets and liabilities and the tax bases of those same assets and liabilities, using the currently enacted statutory tax rates. Deferred income tax expense is measured by the year-to-year change in the net deferred tax asset or liability, except for certain changes in deferred tax amounts that affect stockholders' equity and do not impact federal income tax expense. We reported a federal income tax benefit from continuing and discontinued operations on a consolidated basis of $10,400 and a federal income tax expenses $6,904 for the nine-month periods ended September 30, 2017 and 2016 , respectively. Our effective tax rate is different than the federal statutory rate of 35.0 percent due principally to the effect of tax-exempt municipal bond interest income and non-taxable dividend income. The Company performs a quarterly review of its tax positions and makes a determination of whether it is more likely than not that the tax position will be sustained upon examination. If based on review, it appears not more likely than not that the positions will be sustained, the Company will calculate any unrecognized tax benefits and, if necessary, calculate and accrue any related interest and penalties. We did no t recognize any liability for unrecognized tax benefits at September 30, 2017 or December 31, 2016 . In addition, we have not accrued for interest and penalties related to unrecognized tax benefits. However, if interest and penalties would need to be accrued related to unrecognized tax benefits, such amounts would be recognized as a component of federal income tax expense. With regard to the sale of our life insurance subsidiary, federal income taxes will be allocated to continuing and discontinued operations in accordance with the Company’s tax allocation agreement and the terms of the definitive agreement related to the sale. We file a consolidated federal income tax return. We also file income tax returns in various state jurisdictions. We are no longer subject to federal or state income tax examination for years before 2014. The Internal Revenue Service is conducting routine examinations of our income tax return for the 2015 tax year. Subsequent Events In the preparation of the accompanying financial statements, the Company has evaluated all material subsequent events or transactions that occurred after the balance sheet date through the date on which the financial statements were issued for potential recognition or disclosure in the Company's financial statements. The Company concluded there are no material subsequent events or transactions that have occurred after the balance sheet date through the date on which the financial statements were issued. Recently Issued Accounting Standards Accounting Standards Adopted in 2017 Share-Based Payments In March 2016, the Financial Accounting Standards Board ("FASB") issued new guidance on the accounting for share-based payments. The new guidance was issued to simplify the accounting of share-based payments, specifically in the areas of income taxes, classification on the balance sheets as liabilities or equity and classification in the cash flow statement. The new guidance is effective for annual periods beginning after December 15, 2016 and interim periods within those years. The Company adopted the new guidance prospectively as of January 1, 2017. The new guidance resulted in classification changes between the financing and operating section of the Statement of Cash Flow for stock based compensation expense. The adoption also resulted in a tax benefit of $62 and $546 during the three- and nine-months ended September 30, 2017. Income Taxes In December 2015, the FASB issued guidance on the balance sheet classification of deferred taxes. The new guidance eliminates the requirement to split deferred tax liabilities and assets between current and non-current in a classified balance sheet. The new guidance allows deferred tax liabilities and assets to be included in non-current accounts. The Company adopted the new guidance as of January 1, 2017. The adoption had no impact on the Company's financial position and results of operations since we do not currently report deferred taxes in classified balance sheets. Pending Adoption of Accounting Standards Revenue Recognition In May 2014, the FASB issued comprehensive new guidance on revenue recognition which supersedes nearly all existing revenue recognition guidance under GAAP. The new guidance requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard creates a five-step model that requires companies to exercise judgment when considering the terms of the contract(s) and all relevant facts and circumstances. Insurance contracts are not within the scope of this new guidance. The new guidance is effective for annual and interim periods beginning after December 15, 2017. The Company will adopt the guidance as of January 1, 2018. The Company has completed its review of revenue streams under this new guidance and concluded that the adoption of the new guidance will have no impact on the Company's reporting and disclosure of net premiums earned from insurance contracts, net investment income or net realized gains and losses, as these items are not within the scope of this new guidance. The Company's primary revenue streams from insurance contracts, investment income and net realized gains and losses, are out of scope under this new guidance. The remaining revenue streams are immaterial and not impacted by the new standard. Financial Instruments In January 2016, the FASB issued guidance updating certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments in this update supersede the guidance to classify equity securities with readily determinable fair values into different categories (for example, trading or available-for-sale) and require equity securities to be measured at fair value with changes in the fair value recognized through net income. The new guidance also simplifies the impairment process for equity investments without readily determinable fair values. The new guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those years. The Company will adopt the new guidance as of January 1, 2018. If the new guidance were adopted as of September 30, 2017, there would be a reclassification from accumulated other comprehensive income to retained earnings equal to the amount of net unrealized gains and losses on available-for-sale equity securities at December 31, 2016 disclosed in Note 2 "Summary of Investments," of this section. The impact to net realized gains (losses) would equal the change in net unrealized gains and losses on available-for-sale equity securities between September 30, 2017 and December 31, 2016, in the same tables. Statement of Cash Flows - Classification of Certain Cash Receipts and Payments In August 2016, the FASB issued an update that clarifies the classification of certain cash receipts and payments in the Statement of Cash Flows. The update addresses eight existing cash flow issues by clarifying the correct classification to establish uniformity in practice. The updated guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those years. The Company will adopt the new guidance as of January 1, 2018 and is currently reviewing the updates to the eight existing cash flow issues. Currently, management believes that one existing cash flow issue will be impacted by these updates. Management believes the update will have no impact on the Company's financial position and results of operations but may effect the current classification of the cash flow in the Statement of Cash Flows. Defined Benefit Retirement Plan Cost In March 2017, the FASB issued guidance on the presentation of net periodic benefit costs of defined benefit retirement benefit plans in the Statements of Income. The new guidance requires the service cost component of net periodic benefit cost of defined benefit plans to be presented in the same line in the Statements of Income as other employee compensation expenses. Also, under the new guidance, the service cost component of the net periodic benefit costs will be the only portion of costs subject to be capitalized in assets. The new guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those years. The Company will adopt the new guidance as of January 1, 2018 and is currently evaluating the presentation of net periodic benefit costs in its financial statements and the impact on the Company's financial position and results of operations. Share-Based Payments In May 2017, the FASB issued new guidance which clarifies and addresses the diversity in practice when there is a change in the terms of a share-based payment award. The updated guidance clarifies when to use modification accounting when there is a change in the terms of a share-based payment and provides three conditions where modification accounting should not be applied. The new guidance is effective for annual and interim periods beginning after December 15, 2017. The Company will adopt the new guidance as of January 1, 2018 and is currently evaluating the impact on the Company's financial position and results of operations. Leases In February 2016, the FASB issued guidance on the accounting for leases. The new guidance requires lessees to place most leases on their balance sheets with expenses recognized on the income statement in a similar manner as previous methods. The new guidance is effective for annual periods beginning after December 15, 2018 and interim periods within those years. The Company will adopt the new guidance as of January 1, 2019. The Company has created an inventory of its leases and has calculated the current minimum future lease payment, which is disclosed in Note 13 "Lease Commitments" of our Annual Report on Form 10-K for the year ended December 31, 2016. Financial Instruments - Credit Losses In June 2016, the FASB issued new guidance on the measurement of credit losses for most financial instruments. The new guidance replaces the current incurred loss model for recognizing credit losses with an expected loss model for instruments measured at amortized cost and requires allowances to be recorded for available-for-sale debt securities rather than reduce the carrying amount. These allowances will be remeasured each reporting period. The new guidance is effective for annual periods beginning after December 15, 2020 and interim periods within those years. The Company will adopt the new guidance as of January 1, 2021 and is currently evaluating the impact on the Company's financial position, results of operations and key processes. Income Taxes - Intra-entity Transfers In October 2016, the FASB issued new guidance on the income tax treatment of intra-entity transfers. The new guidance replaces the current guidance which prohibits the recognition of current and deferred income taxes of intra-entity transfers until the asset is sold externally. Under the new guidance, the exemption is eliminated and income taxes will be recognized on transfers of intra-entity assets. The new guidance is effective for annual periods beginning after December 15, 2018 and interim periods beginning after December 15, 2019. The Company will adopt the new guidance as of January 1, 2019 and is currently evaluating the impact on the Company's financial position and results of operations. Goodwill In January 2017, the FASB issued new guidance which simplifies the test for goodwill impairment. The new guidance eliminates the implied fair value calculation when measuring a goodwill impairment charge. Under the new guidance, impairment charges will be based on the excess of the carrying value over fair value of goodwill. The new guidance is effective for annual and interim periods beginning after December 15, 2019. The Company will adopt the new guidance as of January 1, 2020 and is currently evaluating the impact on the Company's financial position and results of operations.

The first table includes consolidated investments from both continuing and discontinued operations. The second and third tables separate maturities into continuing and discontinued operations. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Asset-backed securities, mortgage-backed securities and collateralized mortgage obligations may be subject to prepayment risk and are therefore not categorized by contractual maturity.

A summary of the components of net realized investment gains (losses) is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Net realized investment gains (losses) from continuing operations: Fixed maturities: Available-for-sale $ 118 $ 484 $ 645 $ 898 Trading securities Change in fair value (43 ) 148 504 519 Sales 72 107 117 568 Equity securities: Available-for-sale 3 1,375 1,553 2,359 Trading securities Change in fair value (124 ) (5 ) 232 325 Sales 41 20 57 (6 ) Cash equivalents — — — 169 Real estate — — 289 — Total net realized investment gains from continuing operations $ 67 $ 2,129 $ 3,397 $ 4,832 Total net realized investment gains from discontinued operations 296 461 3,600 1,409 Total net realized investment gains $ 363 $ 2,590 $ 6,997 $ 6,241 The proceeds and gross realized gains on the sale of available-for-sale fixed maturity securities from continuing operations are as follows: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Proceeds from sales $ 2,293 $ — $ 3,388 $ 1,968 Gross realized gains — — 1,046 921 Gross realized losses — — — — The proceeds and gross realized gains on the sale of available-for-sale fixed maturity securities from discontinued operations are as follows: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Proceeds from sales $ 1,844 $ 2,007 $ 5,807 $ 3,081 Gross realized gains — 11 1,254 65 Gross realized losses — — (78 ) — There were no sales of held-to-maturity securities during the three- and nine-month periods ended September 30, 2017 and 2016 . Our investment portfolio includes trading securities with embedded derivatives. These securities are primarily convertible securities which are recorded at fair value. Income or loss, including the change in the fair value of these trading securities, is recognized currently in earnings as a component of net realized investment gains. Our portfolio of trading securities had a fair value of $20,003 and $20,034 at September 30, 2017 and December 31, 2016 , respectively. Funding Commitment Pursuant to an agreement with one of our limited liability partnership investments, we are contractually committed through December 31, 2023 to make capital contributions upon request of the partnership. Our remaining potential contractual obligation was $3,738 at September 30, 2017 . Unrealized Appreciation A summary of the changes in net unrealized investment appreciation during the reporting period is as follows: Nine Months Ended September 30, 2017 2016 Change in net unrealized investment appreciation Available-for-sale fixed maturities $ 34,837 $ 83,498 Available-for-sale equity securities 27,559 15,459 Deferred policy acquisition costs (3,582 ) (19,857 ) Income tax effect (20,584 ) (27,685 ) Total change in net unrealized investment appreciation, net of tax $ 38,230 $ 51,415 We continually monitor the difference between our cost basis and the estimated fair value of our investments. Our accounting policy for impairment recognition requires other-than-temporary impairment ("OTTI") charges to be recorded when we determine that it is more likely than not that we will be unable to collect all amounts due according to the contractual terms of the fixed maturity security or that the anticipated recovery in fair value of the equity security will not occur in a reasonable amount of time. Impairment charges on investments are recorded based on the fair value of the investments at the measurement date or based on the value calculated using a discounted cash flow model. Credit-related impairments on fixed maturity securities that we do not plan to sell, and for which we are not more likely than not to be required to sell, are recognized in net income. Any non-credit related impairment is recognized as a component of other comprehensive income. Factors considered in evaluating whether a decline in value is other-than-temporary include: the length of time and the extent to which fair value has been less than cost; the financial condition and near-term prospects of the issuer; our intention to hold the investment; and the likelihood that we will be required to sell the investment. The tables on the following pages summarize our fixed maturity and equity securities that were in an unrealized loss position on a consolidated basis, including both continuing and discontinued operations at September 30, 2017 and December 31, 2016 . The securities are presented by the length of time they have been continuously in an unrealized loss position. It is possible that we could recognize OTTI charges in future periods on securities held at September 30, 2017 , if future events or information cause us to determine that a decline in fair value is other-than-temporary. We have evaluated the near-term prospects of the issuers of our fixed maturity securities in relation to the severity and duration of the unrealized loss and determined that these losses did not warrant the recognition of an OTTI charge at September 30, 2017 or at September 30, 2016 . We have no intent to sell, and it is more likely than not that we will not be required to sell, these securities until the fair value recovers to at least equal our cost basis or the securities mature. We have evaluated the near-term prospects of the issuers of our equity securities in relation to the severity and duration of the unrealized loss and determined that these losses did not warrant the recognition of an OTTI charge at September 30, 2017 or at September 30, 2016 . Our largest unrealized loss greater than 12 months on an individual equity security at September 30, 2017 was $152 . We have no intention to sell any of these securities prior to a recovery in value, but will continue to monitor the fair value reported for these securities as part of our overall process to evaluate investments for OTTI recognition.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS Current accounting guidance on fair value measurements includes the application of a fair value hierarchy that requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Our financial instruments that are recorded at fair value are categorized into a three-level hierarchy, which is based upon the priority of the inputs to the valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets (i.e., Level 1) and the lowest priority to unobservable inputs (i.e., Level 3). If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the financial instrument. Financial instruments recorded at fair value are categorized in the fair value hierarchy as follows: • Level 1 : Valuations are based on unadjusted quoted prices in active markets for identical financial instruments that we have the ability to access. • Level 2 : Valuations are based on quoted prices for similar financial instruments, other than quoted prices included in Level 1, in markets that are not active or on inputs that are observable either directly or indirectly for the full term of the financial instrument. • Level 3 : Valuations are based on pricing or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement of the financial instrument. Such inputs may reflect management's own assumptions about the assumptions a market participant would use in pricing the financial instrument. We review our fair value hierarchy categorizations on a quarterly basis at which time the classification of certain financial instruments may change if the input observations have changed. Transfers between levels, if any, are recorded as of the beginning of the reporting period. To determine the fair value of the majority of our investments, we utilize prices obtained from independent, nationally recognized pricing services. We obtain one price for each security. When the pricing services cannot provide a determination of fair value for a specific security, we obtain non-binding price quotes from broker-dealers with whom we have had several years experience and who have demonstrated knowledge of the subject security. We request and utilize one broker quote per security. In order to determine the proper classification in the fair value hierarchy for each security where the price is obtained from an independent pricing service, we obtain and evaluate the vendors' pricing procedures and inputs used to price the security, which include unadjusted quoted market prices for identical securities, such as a New York Stock Exchange closing price, and quoted prices for identical securities in markets that are not active. For fixed maturity securities, an evaluation of interest rates and yield curves observable at commonly quoted intervals, volatility, prepayment speeds, credit risks and default rates may also be performed. We have determined that these processes and inputs result in fair values and classifications consistent with the applicable accounting guidance on fair value measurements. When possible, we use quoted market prices to determine the fair value of fixed maturities, equity securities, trading securities and short-term investments. When quoted market prices do not exist, we base estimates of fair value on market information obtained from independent pricing services and brokers or on valuation techniques that are both unobservable and significant to the overall fair value measurement of the financial instrument. Such inputs may reflect management's own assumptions about the assumptions a market participant would use in pricing the financial instrument. Our valuation techniques are discussed in more detail throughout this section. The fair value of our mortgage loans is determined by modeling performed by us based on the stated principal and coupon payments provided for in the loan agreements. These cash flows are then discounted using an appropriate risk-adjusted discount rate to determine the security's fair value, which is a Level 3 fair value measurement. The fair value of our policy loans is equivalent to carrying value, which is a reasonable estimate of fair value and is classified as Level 2. We do not make policy loans for amounts in excess of the cash surrender value of the related policy. In all instances, the policy loans are fully collateralized by the related liability for future policy benefits for traditional insurance policies or by the policyholders' account balance for non-traditional policies. Our other long-term investments consist primarily of our interests in limited liability partnerships that are recorded on the equity method of accounting. The fair value of the partnerships is obtained from the fund managers, which is based on the fair value of the underlying investments held in the partnerships. In management's opinion, these values represent a reasonable estimate of fair value. We have not adjusted the net asset value provided by the fund managers. For cash and cash equivalents and accrued investment income, carrying value is a reasonable estimate of fair value due to the short-term nature of these financial instruments. The Company formed a rabbi trust in 2014 to fund obligations under the United Fire & Casualty Company Non-qualified Deferred Compensation Plan and United Fire Group Supplemental Executive Retirement and Deferral Plan (collectively, the "Executive Retirement Plans"). Within the rabbi trust, corporate-owned life insurance ("COLI") policies are utilized as an investment vehicle and source of funding for the Company's Executive Retirement Plans. The COLI policies invest in mutual funds, which are priced daily by independent sources. As of September 30, 2017 , the cash surrender value of the COLI policies was $3,759 , which is equal to the fair value measured using Level 2 inputs, based on the underlying assets of the COLI policies, and is included in other assets in the Consolidated Balance Sheets. Policy reserves are developed and recorded for deferred annuities, which is an interest-sensitive product, and income annuities. The fair value of the reserve liability for these annuity products is based upon an estimate of the discounted pretax cash flows that are forecast for the underlying business, which is a Level 3 fair value measurement. We base the discount rate on the current U.S. Treasury spot yield curve, which is then risk-adjusted for nonperformance risk and, for interest-sensitive business and market risk factors. The risk-adjusted discount rate is developed using interest rates that are available in the market and representative of the risks applicable to the underlying business.

Total Assets Measured at Fair Value $ 3,208,145 $ 289,755 $ 2,903,292 $ 15,098 The fair value of securities that are categorized as Level 1 is based on quoted market prices that are readily and regularly available. We use a market-based approach for valuing all of our Level 2 securities and submit them primarily to a third-party valuation service provider. Any of these securities not valued by this service provider are submitted to another third-party valuation service provider. Both service providers use a market approach to find pricing of similar financial instruments. The market inputs our service providers normally seek to value our securities include the following, listed in approximate order of priority: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. The method and inputs for these securities classified as Level 2 are the same regardless of industry category, credit quality, duration, geographical concentration or economic characteristics. For our mortgage-backed securities, collateralized mortgage obligations and asset-backed securities, our service providers use additional market inputs to value these securities, including the following: new issue data, periodic payment information, monthly payment information, collateral performance and real estate analysis from third parties. Our service providers prioritize inputs based on market conditions, and not all inputs listed are available for use in the valuation process for each security on any given day. At least annually, we review the methodologies and assumptions used by our valuation service providers and verify that they are reasonable and representative of the fair value of the underlying securities held in the investment portfolio. We validate the prices obtained from independent pricing services and brokers prior to their use for reporting purposes by evaluating their reasonableness on a monthly basis. Our validation process includes a review for unusual fluctuations. Unusual fluctuations outside of our expectations are independently corroborated with additional third-party sources that use similar valuation techniques as discussed above. In addition, we also randomly select securities and independently corroborate the valuations obtained from our third-party valuation service providers. In our opinion, the pricing obtained at September 30, 2017 and December 31, 2016 was reasonable. For the three- and nine-month periods ended September 30, 2017 , the change in our available-for-sale securities categorized as Level 1 and Level 2 is the result of investment purchases that were made using funds held in our money market accounts, disposals and the change in unrealized gains on both fixed maturities and equity securities. During the three- and nine-month periods ended September 30, 2017 , there were no securities transferred between Level 1 and Level 2. Securities categorized as Level 3 include holdings in certain private placement fixed maturity and equity securities for which an active market does not currently exist. The fair value of our Level 3 private placement securities is determined by management relying on pricing received from our independent pricing services and brokers consistent with the process to estimate fair value for Level 2 securities. However, securities are categorized as Level 3 if these quotes cannot be corroborated by other market observable data due to the unobservable nature of the brokers’ valuation processes. If pricing cannot be obtained from these sources, which occurs on a limited basis, management will perform a discounted cash flow analysis, using an appropriate risk-adjusted discount rate, on the underlying security to estimate fair value. During the three- and nine-month periods ended September 30, 2017 , there were no securities transferred in or out of Level 3. The following table provides a summary of the changes in fair value of our Level 3 securities, from both continuing and discontinued operations for the three-month period ended September 30, 2017 : States, municipalities and political subdivisions Corporate bonds Asset-backed securities Equities Total Balance at June 30, 2017 $ 77 $ 9,056 $ 622 $ 595 $ 10,350 Net unrealized gains (losses) (1) — (7 ) 9 139 141 Purchases — 100 — — 100 Disposals — (433 ) — — (433 ) Balance at September 30, 2017 $ 77 $ 8,716 $ 631 $ 734 $ 10,158 (1) Net unrealized gains (losses) are recorded as a component of comprehensive income.

Insurance Loss Reserves [Abstract]
Reserves for Losses and Loss Settlement Expenses	RESERVES FOR LOSSES AND LOSS SETTLEMENT EXPENSES Property insurance indemnifies an insured with an interest in physical property for loss of, or damage to, such property or the loss of its income-producing abilities. Casualty insurance primarily covers liability for damage to property of, or injury to, a person or entity other than the insured. In most cases, casualty insurance also obligates the insurance company to provide a defense for the insured in litigation, arising out of events covered by the policy. Liabilities for losses and loss settlement expenses reflect management's best estimates at a given point in time of what we expect to pay for claims that have been reported and those that have been incurred but not reported ("IBNR"), based on known facts, circumstances, and historical trends. Because property and casualty insurance reserves are estimates of the unpaid portions of incurred losses that have been reported to us, as well as losses that have been incurred but not reported, the establishment of appropriate reserves, including reserves for catastrophes, is an inherently uncertain and complex process. The ultimate cost of losses and related loss settlement expenses may vary materially from recorded amounts. We regularly update our reserve estimates as new information becomes available and as events unfold that may affect the resolution of unsettled claims. Changes in prior year reserve estimates, which may be material, are reported as a component of losses and loss settlement expenses incurred in the period such changes are determined. The determination of reserves (particularly those relating to liability lines of insurance that have relatively longer lag in claim reporting) requires significant work to reasonably project expected future claim reporting and payment patterns. If, during the course of our regular monitoring of reserves, we determine that coverages previously written are incurring higher than expected losses, we will take action that may include, among other things, increasing the related reserves. Any adjustments we make to reserves are reflected in operating results in the year in which we make those adjustments. We engage an independent actuary, Regnier Consulting Group, Inc., to render an opinion as to the reasonableness of our statutory reserves annually. The actuarial opinion is filed in those states where we are licensed. On a quarterly basis, UFG's internal actuary performs a detailed actuarial review of IBNR reserves. This review includes a comparison of results from the most recent analysis of reserves completed by both our internal and external actuaries. Senior management meets with our internal actuary to review, on a regular and quarterly basis, the adequacy of carried reserves based on results from this actuarial analysis. There are two fundamental types or sources of IBNR reserves. We record IBNR reserves for "normal" types of claims and also specific IBNR reserves related to unique circumstances or events. A major hurricane is an example of an event that might necessitate establishing specific IBNR reserves because an analysis of existing historical data would not provide an appropriate estimate. We do not discount loss reserves based on the time value of money. The following table provides an analysis of changes in our property and casualty losses and loss settlement expense reserves at September 30, 2017 and December 31, 2016 (net of reinsurance amounts): September 30, 2017 December 31, 2016 Gross liability for losses and loss settlement expenses $ 1,123,896 $ 1,003,895 Ceded losses and loss settlement expenses (59,794 ) (54,653 ) Net liability for losses and loss settlement expenses $ 1,064,102 $ 949,242 Losses and loss settlement expenses incurred Current year $ 606,344 $ 683,662 Prior years (37,988 ) (31,229 ) Total incurred $ 568,356 $ 652,433 Losses and loss settlement expense payments Current year $ 212,591 $ 277,053 Prior years 247,608 260,520 Total paid $ 460,199 $ 537,573 Net liability for losses and loss settlement expenses $ 1,172,259 $ 1,064,102 Ceded loss and loss settlement expenses 65,021 59,794 Gross liability for losses and loss settlement expenses $ 1,237,280 $ 1,123,896 There are a multitude of factors that can impact loss reserve development. Those factors include, but are not limited to: historical data, the potential impact of various loss reserve development factors and trends including historical loss experience, legislative enactments, judicial decisions, legal developments in imposition of damages, experience with alternative dispute resolution, results of our medical bill review process, the potential impact of salvage and subrogation and changes and trends in general economic conditions, including the effects of inflation. All of these factors influence our estimates of required reserves and for long tail lines these factors can change over the course of the settlement of the claim. However, there is no precise method for evaluating the specific dollar impact of any individual factor on the development of reserves. The significant drivers of the favorable reserve development in 2017 came from two lines, commercial liability and workers compensation, partially offset by unfavorable development from commercial fire and allied lines, assumed reinsurance and commercial automobile. Much of the favorable long-tail liability development continues to come from loss adjustment expense and is attributed to our continued litigation management efforts. There was also a reduction in reserves for incurred but not reported claims because our long tail liability has experienced fewer late reported claims than what was initially anticipated. The majority of the favorable workers compensation development is due to reductions in reserves for reported claims which were greater than what was necessary to offset claim payments. Assumed reinsurance was adversely affected by increases in reserves for reported claims while commercial fire adverse development is attributable to loss payments which were greater than reductions in reported loss reserves and reserves for claims incurred but not reported. The majority of adverse commercial fire development resulted from claim payments that exceeded reductions in reserves for reported claims. The significant drivers of the favorable reserve development in 2016 were our commercial liability and workers compensation. Much of the favorable commercial liability development came from loss adjustment expense and is attributed to our continued litigation management efforts. Workers compensation favorable development was due to the combined effects of decreases in claim reserves along with favorable changes affecting loss adjustment expense. Loss adjustment expense, closely tied to loss, generally decreases when loss decreases. Commercial property, commercial automobile and assumed reinsurance exhibited adverse development which provided a partial offset to the favorable development previously noted. The adverse development for all three lines is due to paid loss which was greater than reductions in reported loss reserves and reserves for claims incurred but not reported. No other single line of business contributed a significant portion of the total development. Generally, we base reserves for each claim on the estimated ultimate exposure for that claim. We believe that it is appropriate and reasonable to establish a best estimate for reserves within a range of reasonable estimates, especially when we are reserving for claims for bodily injury, disabilities and similar claims, for which settlements and verdicts can vary widely. Our reserving philosophy may result in favorable reserve development in future years that will decrease losses and loss settlement expenses for prior year claims in the year of adjustment. We realize that this philosophy, coupled with what we believe to be aggressive and successful claims management and loss settlement practices, has resulted in year-to-year redundancies in reserves. We believe our approach produces recorded reserves that are reasonably consistent as to their relative position within a range of reasonable reserves from year-to-year. However, conditions and trends that have affected the reserve development for a given year do change. Therefore, such development cannot be used to project future reserve redundancies or deficiencies. We are not aware of any significant contingent liabilities related to environmental issues. Because of the type of property coverage we write, we have potential exposure to environmental pollution, mold and asbestos claims. Our underwriters are aware of these exposures and use riders or endorsements to limit exposure.

Share-based Compensation [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION Non-qualified Employee Stock Award Plan The United Fire Group, Inc. 2008 Stock Plan (the "2008 Stock Plan") authorized the issuance of restricted and unrestricted stock awards, restricted stock units, stock appreciation rights, incentive stock options, and non-qualified stock options for up to 1,900,000 shares of UFG common stock to employees. In May 2014, the Registrant's shareholders approved an additional 1,500,000 shares of UFG common stock issuable at any time and from time to time pursuant to the 2008 Stock Plan, among other amendments, and renamed such plan as the United Fire Group, Inc. Stock Plan (as amended, the "Stock Plan"). At September 30, 2017 , there were 996,839 authorized shares remaining available for future issuance. The Stock Plan is administered by the Board of Directors, which determines those employees who will receive awards, when awards will be granted, and the terms and conditions of the awards. The Board of Directors may also take any action it deems necessary and appropriate for the administration of the Stock Plan. Pursuant to the Stock Plan, the Board of Directors may, at its sole discretion, grant awards to our employees who are in positions of substantial responsibility with UFG. Options granted pursuant to the Stock Plan are granted to buy shares of UFG's common stock at the market value of the stock on the date of grant. All outstanding option awards have graded vesting over 3 years or 5 years from the grant date, unless the Board of Directors authorizes acceleration of vesting. Performance stock units cliff-vest after 3 years and the certification of performance results by UFG’s Compensation Committee. To the extent not exercised, vested option awards accumulate and are exercisable by the awardee, in whole or in part, in any subsequent year included in the option period, but not later than 10 years from the grant date. Restricted and unrestricted stock awards granted pursuant to the Stock Plan are granted at the market value of UFG's common stock on the date of the grant. Restricted stock units fully vest after 3 years or 5 years from the date of issuance, unless accelerated upon the approval of the Board of Directors, at which time UFG common stock will be issued to the awardee. The activity in the Stock Plan is displayed in the following table: Authorized Shares Available for Future Award Grants Nine Months Ended September 30, 2017 From Inception to September 30, 2017 Beginning balance 1,248,651 1,900,000 Additional shares authorized — 1,500,000 Number of awards granted (255,040 ) (2,867,606 ) Number of awards forfeited or expired 3,228 464,445 Ending balance 996,839 996,839 Number of option awards exercised 101,189 1,050,257 Number of unrestricted stock awards granted 1,145 8,470 Number of restricted stock awards vested — 36,970 Non-qualified Non-employee Director Stock Option and Restricted Stock Plan The United Fire Group, Inc. 2005 Non-qualified Non-employee Director Stock Option and Restricted Stock Plan (the "Director Plan") authorizes the issuance of restricted stock awards and non-qualified stock options to purchase shares of UFG's common stock to non-employee directors. At September 30, 2017 , we had 61,813 authorized shares available for future issuance. The Board of Directors has the authority to determine which non-employee directors receive awards, when options and restricted stock shall be granted, the option price, the option expiration date, the date of grant, the vesting schedule of options or whether the options shall be immediately vested, the terms and conditions of options and restricted stock (other than those terms and conditions set forth in the plan) and the number of shares of common stock to be issued pursuant to an option agreement or restricted stock agreement (subject to limits set forth in the plan). The Board of Directors may also take any action it deems necessary and appropriate for the administration of the Director Plan.

For the nine-month periods ended September 30, 2017 and 2016 , we recognized stock-based compensation expense of $3,456 and $2,731 , respectively. Stock-based compensation expense is recognized over the vesting period of the stock options. As of September 30, 2017 , we had $9,586 in stock-based compensation expense that has yet to be recognized through our results of operations. We expect this compensation to be recognized over the remainder of 2017 and subsequent years according to the table below, except with respect to awards that are accelerated by the Board of Directors, in which case we will recognize any remaining compensation expense in the period in which the awards are accelerated. 2017 $ 1,202 2018 4,047 2019 2,784 2020 1,120 2021 393 2022 40 Total $ 9,586

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION On September 19, 2017, the Company announced that it had agreed to sell its subsidiary, United Life Insurance Company, to Kuvare. As a result, our life insurance segment has been considered held for sale and reported as discontinued operations in the Consolidated Financial Statements and all comparable prior periods have been presented to conform to the current year presentation. The sale is expected to close in the first half of 2018, subject to customary conditions, including regulatory approval. For more information, refer to Note 11. Discontinued Operations. Prior to the announcement to sell our subsidiary, United Life Insurance Company, we had two reportable business segments in our operations: property and casualty insurance and life insurance. The property and casualty insurance segment has six domestic locations from which it conducts its business. The life insurance segment operates from our home office in Cedar Rapids, Iowa. Because all of our insurance is sold domestically, we have no revenues from foreign operations. After the announcement of the sale of our life insurance segment, the Company has one reportable segment, the property and casualty insurance segment, which includes all continuing operations. The property and casualty insurance segment profit or loss is consistent with consolidated reporting as disclosed on the Consolidated Statements of Income and Comprehensive Income. We analyze the property and casualty insurance segment results based on profitability (i.e., loss ratios), expenses and return on equity. The Company's property and casualty insurance segment was determined using a management approach to make decisions on operating matters, including allocating resources, assessing performance, determining which products to market and sell, determining distribution networks with insurance agents and monitoring the regulatory environment. The property and casualty insurance segment products have similar economic characteristics and use a similar marketing and distribution strategy with our independent agents. The property and casualty insurance segment geographic concentration did not change after the announcement of the sale of the life insurance segment. We will continue to evaluate our segment on the basis of both statutory accounting principles prescribed or permitted by our states of domicile and GAAP.

Earnings Per Share [Abstract]
Earnings Per Common Share	EARNINGS PER COMMON SHARE Basic earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding during the reporting period. Diluted earnings per share gives effect to all dilutive common shares outstanding during the reporting period. The dilutive shares we consider in our diluted earnings per share calculation relate to our outstanding stock options, restricted stock awards and restricted stock unit awards. We determine the dilutive effect of our outstanding stock options using the "treasury stock" method. Under this method, we assume the exercise of all of the outstanding stock options whose exercise price is less than the weighted-average market value of our common stock during the reporting period. This method also assumes that the proceeds from the hypothetical stock option exercises are used to repurchase shares of our common stock at the weighted-average market value of the stock during the reporting period. The net of the assumed stock options exercised and assumed common shares repurchased represents the number of dilutive common shares, which we add to the denominator of the earnings per share calculation. The components of basic and diluted earnings per share were as follows for the three-month periods ended September 30, 2017 and 2016 : Three Months Ended September 30, (In Thousands, Except Share Data) 2017 2016 Basic Diluted Basic Diluted Net income (loss) from continuing operations $ (19,082 ) $ (19,082 ) $ 11,628 $ 11,628 Weighted-average common shares outstanding 24,960,086 24,960,086 25,389,633 25,389,633 Add dilutive effect of restricted stock unit awards — — — 155,270 Add dilutive effect of stock options — — — 270,443 Weighted-average common shares outstanding 24,960,086 24,960,086 25,389,633 25,815,346 Earnings (loss) per common share from continuing operations $ (0.77 ) $ (0.77 ) $ 0.46 $ 0.45 Earnings per common share from discontinued operations 0.05 0.05 0.03 0.03 Earnings (loss) per common share $ (0.72 ) $ (0.72 ) $ 0.49 $ 0.48 Awards excluded from diluted earnings per share calculation (1) — — — — (1) Outstanding awards that are not "in-the-money" are excluded from the diluted earnings per share calculation because the effect of including them would have been anti-dilutive.

Debt Disclosure [Abstract]
Credit Facility	CREDIT FACILITY On February 2, 2016, the Company, as borrower, entered into a Credit Agreement (the "Credit Agreement") by and among the Company, with the lenders from time to time party thereto and KeyBank National Association ("Key Bank"), as administrative agent, swingline lender and letter of credit issuer. The Credit Agreement provides for a $50,000 four -year unsecured revolving credit facility that includes a $20,000 letter of credit subfacility and a swingline subfacility in the amount up to $5,000 . The Credit Agreement allows the Company to increase the aggregate amount of the commitments thereunder by up to $100,000 , provided that no event of default has occurred and is continuing and certain other conditions are satisfied. The Credit Agreement is available for the Company's general corporate purposes, including liquidity, acquisitions and working capital. All unpaid principal and accrued interest under the Credit Agreement is due and payable in full at maturity on February 2, 2020. Based on the type of loan, advances under the Credit Agreement would bear interest on either the London interbank offered rate ("LIBOR") or a base rate plus, in each case, a calculated margin amount. The unused commitments under the Credit Agreement will be subject to a commitment fee that will be calculated at a per annum rate. The applicable margins for borrowings under the Credit Agreement and the commitment fee thereunder will be determined by reference to a pricing grid based on the Company’s issuer credit rating by A.M. Best Company, Inc. The Credit Agreement contains customary representations, conditions to borrowing, covenants and events of default, including certain covenants that limit or restrict, subject to certain exceptions, the ability of the Company and its subsidiaries to sell or transfer assets, enter into a merger or consolidate with another company, create liens, impose restrictions on subsidiary dividends, enter into sale-leaseback transactions, make investments or acquisitions, enter into certain reinsurance agreements, pay dividends during any period of default, enter into transactions with affiliates, change the nature of its business, or incur indebtedness.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	DISCONTINUED OPERATIONS On September 18, 2017, we signed a definitive agreement to sell our subsidiary, United Life Insurance Company, to Kuvare for $280,000 in cash, subject to specified adjustments as set forth in the definitive agreement. As a result, our life insurance business (previously reported as a separate segment) has been considered held for sale and reported as discontinued operations and its financial position, results of operations and cash flows are separately reported separately for all periods presented, unless otherwise noted. The sale is expected to close in the first half of 2018, subject to customary conditions, including regulatory approval. Subsequent to the close of the sale in the first half of 2018, UFG will provide services to Kuvare through a transition services agreement ("TSA"). The TSA will be put in place to ensure a seamless transfer of the business between UFG and Kuvare. The TSA includes, among other considerations, accounting management, human resources, legal and information technology services, from the closing date for up to 24 months. The assets and liabilities associated with discontinued operations prior to the closing of the sale have been presented separately in our Consolidated Balance Sheets. The major assets and liability categories were as follows as of the dates indicated: Discontinued Operations Balance Sheets (In Thousands, Except Share Data) September 30, December 31, (unaudited) Assets Investments Fixed maturities Held-to-maturity, at amortized cost (fair value $39 in 2017 and $49 in 2016) $ 38 $ 48 Available-for-sale, at fair value (amortized cost $1,399,465 in 2017 and $1,429,270 in 2016) 1,426,991 1,444,840 Equity Securities available-for-sale, at fair value (cost $5,099 in 2017 and $8,510 in 2016) 22,616 24,046 Mortgage loans 3,504 3,706 Policy loans 5,770 5,366 Other long-term investments 16,299 15,870 1,475,218 1,493,876 Cash and cash equivalents 30,751 21,659 Deferred policy acquisition costs 65,836 70,750 Other assets 21,041 19,333 Total assets held for sale $ 1,592,846 $ 1,605,618 Liabilities Future policy benefits and losses $ 1,324,029 $ 1,350,503 Accrued expenses and other liabilities 39,708 39,720 Total liabilities held for sale $ 1,363,737 $ 1,390,223 Summary operating results of discontinued operations were as follows for the periods indicated: Discontinued Operations Statements of Income Three Months Ended September 30, Nine Months Ended September 30, (In Thousands, Except Share Data) 2017 2016 2017 2016 Revenues Net premiums earned $ 14,230 $ 20,600 $ 45,999 $ 62,878 Investment income, net of investment expenses 12,354 12,663 37,230 38,404 Net realized investment gains 296 461 3,600 1,409 Other income 174 145 498 436 Total revenues $ 27,054 $ 33,869 $ 87,327 $ 103,127 Benefits, Losses and Expenses Losses and loss settlement expenses $ 10,506 $ 7,252 $ 30,679 $ 23,527 Increase in liability for future policy benefits 5,481 14,091 19,341 42,645 Amortization of deferred policy acquisition costs 2,156 1,876 5,524 5,716 Other underwriting expenses 2,444 4,527 9,452 14,630 Interest on policyholders’ accounts 4,587 4,983 13,982 15,368 Total benefits, losses and expenses $ 25,174 $ 32,729 $ 78,978 $ 101,886 Income from discontinued operations before income taxes $ 1,880 $ 1,140 $ 8,349 $ 1,241 Federal income tax expense 662 400 2,930 415 Net income from discontinued operations $ 1,218 $ 740 $ 5,419 $ 826 Earnings per common share from discontinued operations: Basic $ 0.05 $ 0.03 $ 0.21 $ 0.03 Diluted 0.05 0.03 0.21 0.03 The Company's Consolidated Statement of Cash Flows presents operating, investing and financing cash flows of the discontinued operations separately.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Discontinued Operations	Discontinued Operations We have historically reported our operations in two business segments: property and casualty insurance and life insurance. On September 18, 2017, the Company signed a definitive agreement to sell its subsidiary, United Life Insurance Company, to Kuvare US Holdings, Inc. ("Kuvare"). As a result, our life insurance business, previously a separate segment, has been considered held for sale and reported as discontinued operations in the Consolidated Balance Sheets, Consolidated Statements of Income and Comprehensive Income and Consolidated Statements of Cash Flows (collectively, the "Consolidated Financial Statements"). Subsequent to the announcement of this sale, our continuing operations are now reported as one business segment. All current and prior periods reflected in this Form 10-Q have been presented as continuing and discontinued operations, unless otherwise noted. The sale is expected to close in the first half of 2018, subject to customary conditions, including regulatory approval.
Basis of Presentation	Basis of Presentation The unaudited consolidated interim financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial reporting and with the instructions to Form 10-Q and Regulation S-X promulgated by the SEC. Certain financial information that is included in our Annual Report on Form 10-K, including certain financial statement footnote disclosures, are not required by the rules and regulations of the SEC for interim financial reporting and have been condensed or omitted.
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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 from those estimates. The financial statement categories that are most dependent on management estimates and assumptions include: investments; deferred policy acquisition costs; reinsurance receivables and recoverables; future policy benefits and losses, claims and loss settlement expenses; and pension and postretirement benefit obligations.
Reclassification	Certain prior year amounts have been reclassified to conform to the current year presentation.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash, money market accounts, and non-negotiable certificates of deposit with original maturities of three months or less.
Deferred Policy Acquisition Costs (DAC)	Deferred Policy Acquisition Costs ("DAC") Certain costs associated with underwriting new business (primarily commissions, premium taxes and variable underwriting and policy issue expenses associated with successful acquisition efforts) are deferred. The following table is a summary of the components of DAC, including the related amortization recognized for the nine-month period ended September 30, 2017 . Continuing Operations Discontinued Operations Property & Casualty Insurance Life Insurance Total Recorded asset at beginning of period $ 93,362 $ 70,750 $ 164,112 Underwriting costs deferred 158,960 4,192 163,152 Amortization of deferred policy acquisition costs (154,845 ) (5,524 ) (160,369 ) Ending unamortized deferred policy acquisition costs $ 97,477 $ 69,418 $ 166,895 Impact of unrealized gains and losses on available-for-sale securities — (3,582 ) (3,582 ) Recorded asset at September 30, 2017 $ 97,477 $ 65,836 $ 163,313 Property and casualty insurance policy acquisition costs deferred are amortized as premium revenue is recognized. The method followed in computing DAC limits the amount of such deferred costs to their estimated realizable value. This takes into account the premium to be earned, losses and loss settlement expenses expected to be incurred and certain other costs expected to be incurred as the premium is earned. For traditional life insurance policies, DAC is amortized to income over the premium-paying period in proportion to the ratio of the expected annual premium revenue to the expected total premium revenue. Expected premium revenue and gross profits are based on the same mortality and withdrawal assumptions used in determining future policy benefits. These assumptions are not revised after policy issuance unless the recorded DAC asset is deemed to be unrecoverable from future expected profits. For non-traditional life insurance policies, DAC is amortized over the anticipated terms in proportion to the ratio of the expected annual gross profits to the total expected gross profits. Changes in the amount or timing of expected gross profits result in adjustments to the cumulative amortization of these costs. The effect on amortization of DAC for revisions to estimated gross profits is reported in earnings in the period the estimated gross profits are revised. The effect on DAC that results from the assumed realization of unrealized gains (losses) on investments allocated to non-traditional life insurance business is recognized with an offset to net unrealized investment appreciation as of the balance sheet date.
Income Taxes	Income Taxes Deferred tax assets and liabilities are established based on differences between the financial statement bases of assets and liabilities and the tax bases of those same assets and liabilities, using the currently enacted statutory tax rates. Deferred income tax expense is measured by the year-to-year change in the net deferred tax asset or liability, except for certain changes in deferred tax amounts that affect stockholders' equity and do not impact federal income tax expense. We reported a federal income tax benefit from continuing and discontinued operations on a consolidated basis of $10,400 and a federal income tax expenses $6,904 for the nine-month periods ended September 30, 2017 and 2016 , respectively. Our effective tax rate is different than the federal statutory rate of 35.0 percent due principally to the effect of tax-exempt municipal bond interest income and non-taxable dividend income. The Company performs a quarterly review of its tax positions and makes a determination of whether it is more likely than not that the tax position will be sustained upon examination. If based on review, it appears not more likely than not that the positions will be sustained, the Company will calculate any unrecognized tax benefits and, if necessary, calculate and accrue any related interest and penalties. We did no t recognize any liability for unrecognized tax benefits at September 30, 2017 or December 31, 2016 . In addition, we have not accrued for interest and penalties related to unrecognized tax benefits. However, if interest and penalties would need to be accrued related to unrecognized tax benefits, such amounts would be recognized as a component of federal income tax expense. With regard to the sale of our life insurance subsidiary, federal income taxes will be allocated to continuing and discontinued operations in accordance with the Company’s tax allocation agreement and the terms of the definitive agreement related to the sale. We file a consolidated federal income tax return. We also file income tax returns in various state jurisdictions. We are no longer subject to federal or state income tax examination for years before 2014. The Internal Revenue Service is conducting routine examinations of our income tax return for the 2015 tax year.
Subsequent Events	Subsequent Events In the preparation of the accompanying financial statements, the Company has evaluated all material subsequent events or transactions that occurred after the balance sheet date through the date on which the financial statements were issued for potential recognition or disclosure in the Company's financial statements.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Accounting Standards Adopted in 2017 Share-Based Payments In March 2016, the Financial Accounting Standards Board ("FASB") issued new guidance on the accounting for share-based payments. The new guidance was issued to simplify the accounting of share-based payments, specifically in the areas of income taxes, classification on the balance sheets as liabilities or equity and classification in the cash flow statement. The new guidance is effective for annual periods beginning after December 15, 2016 and interim periods within those years. The Company adopted the new guidance prospectively as of January 1, 2017. The new guidance resulted in classification changes between the financing and operating section of the Statement of Cash Flow for stock based compensation expense. The adoption also resulted in a tax benefit of $62 and $546 during the three- and nine-months ended September 30, 2017. Income Taxes In December 2015, the FASB issued guidance on the balance sheet classification of deferred taxes. The new guidance eliminates the requirement to split deferred tax liabilities and assets between current and non-current in a classified balance sheet. The new guidance allows deferred tax liabilities and assets to be included in non-current accounts. The Company adopted the new guidance as of January 1, 2017. The adoption had no impact on the Company's financial position and results of operations since we do not currently report deferred taxes in classified balance sheets. Pending Adoption of Accounting Standards Revenue Recognition In May 2014, the FASB issued comprehensive new guidance on revenue recognition which supersedes nearly all existing revenue recognition guidance under GAAP. The new guidance requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard creates a five-step model that requires companies to exercise judgment when considering the terms of the contract(s) and all relevant facts and circumstances. Insurance contracts are not within the scope of this new guidance. The new guidance is effective for annual and interim periods beginning after December 15, 2017. The Company will adopt the guidance as of January 1, 2018. The Company has completed its review of revenue streams under this new guidance and concluded that the adoption of the new guidance will have no impact on the Company's reporting and disclosure of net premiums earned from insurance contracts, net investment income or net realized gains and losses, as these items are not within the scope of this new guidance. The Company's primary revenue streams from insurance contracts, investment income and net realized gains and losses, are out of scope under this new guidance. The remaining revenue streams are immaterial and not impacted by the new standard. Financial Instruments In January 2016, the FASB issued guidance updating certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments in this update supersede the guidance to classify equity securities with readily determinable fair values into different categories (for example, trading or available-for-sale) and require equity securities to be measured at fair value with changes in the fair value recognized through net income. The new guidance also simplifies the impairment process for equity investments without readily determinable fair values. The new guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those years. The Company will adopt the new guidance as of January 1, 2018. If the new guidance were adopted as of September 30, 2017, there would be a reclassification from accumulated other comprehensive income to retained earnings equal to the amount of net unrealized gains and losses on available-for-sale equity securities at December 31, 2016 disclosed in Note 2 "Summary of Investments," of this section. The impact to net realized gains (losses) would equal the change in net unrealized gains and losses on available-for-sale equity securities between September 30, 2017 and December 31, 2016, in the same tables. Statement of Cash Flows - Classification of Certain Cash Receipts and Payments In August 2016, the FASB issued an update that clarifies the classification of certain cash receipts and payments in the Statement of Cash Flows. The update addresses eight existing cash flow issues by clarifying the correct classification to establish uniformity in practice. The updated guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those years. The Company will adopt the new guidance as of January 1, 2018 and is currently reviewing the updates to the eight existing cash flow issues. Currently, management believes that one existing cash flow issue will be impacted by these updates. Management believes the update will have no impact on the Company's financial position and results of operations but may effect the current classification of the cash flow in the Statement of Cash Flows. Defined Benefit Retirement Plan Cost In March 2017, the FASB issued guidance on the presentation of net periodic benefit costs of defined benefit retirement benefit plans in the Statements of Income. The new guidance requires the service cost component of net periodic benefit cost of defined benefit plans to be presented in the same line in the Statements of Income as other employee compensation expenses. Also, under the new guidance, the service cost component of the net periodic benefit costs will be the only portion of costs subject to be capitalized in assets. The new guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those years. The Company will adopt the new guidance as of January 1, 2018 and is currently evaluating the presentation of net periodic benefit costs in its financial statements and the impact on the Company's financial position and results of operations. Share-Based Payments In May 2017, the FASB issued new guidance which clarifies and addresses the diversity in practice when there is a change in the terms of a share-based payment award. The updated guidance clarifies when to use modification accounting when there is a change in the terms of a share-based payment and provides three conditions where modification accounting should not be applied. The new guidance is effective for annual and interim periods beginning after December 15, 2017. The Company will adopt the new guidance as of January 1, 2018 and is currently evaluating the impact on the Company's financial position and results of operations. Leases In February 2016, the FASB issued guidance on the accounting for leases. The new guidance requires lessees to place most leases on their balance sheets with expenses recognized on the income statement in a similar manner as previous methods. The new guidance is effective for annual periods beginning after December 15, 2018 and interim periods within those years. The Company will adopt the new guidance as of January 1, 2019. The Company has created an inventory of its leases and has calculated the current minimum future lease payment, which is disclosed in Note 13 "Lease Commitments" of our Annual Report on Form 10-K for the year ended December 31, 2016. Financial Instruments - Credit Losses In June 2016, the FASB issued new guidance on the measurement of credit losses for most financial instruments. The new guidance replaces the current incurred loss model for recognizing credit losses with an expected loss model for instruments measured at amortized cost and requires allowances to be recorded for available-for-sale debt securities rather than reduce the carrying amount. These allowances will be remeasured each reporting period. The new guidance is effective for annual periods beginning after December 15, 2020 and interim periods within those years. The Company will adopt the new guidance as of January 1, 2021 and is currently evaluating the impact on the Company's financial position, results of operations and key processes. Income Taxes - Intra-entity Transfers In October 2016, the FASB issued new guidance on the income tax treatment of intra-entity transfers. The new guidance replaces the current guidance which prohibits the recognition of current and deferred income taxes of intra-entity transfers until the asset is sold externally. Under the new guidance, the exemption is eliminated and income taxes will be recognized on transfers of intra-entity assets. The new guidance is effective for annual periods beginning after December 15, 2018 and interim periods beginning after December 15, 2019. The Company will adopt the new guidance as of January 1, 2019 and is currently evaluating the impact on the Company's financial position and results of operations. Goodwill In January 2017, the FASB issued new guidance which simplifies the test for goodwill impairment. The new guidance eliminates the implied fair value calculation when measuring a goodwill impairment charge. Under the new guidance, impairment charges will be based on the excess of the carrying value over fair value of goodwill. The new guidance is effective for annual and interim periods beginning after December 15, 2019. The Company will adopt the new guidance as of January 1, 2020 and is currently evaluating the impact on the Company's financial position and results of operations.
Fair Value Measurement	Current accounting guidance on fair value measurements includes the application of a fair value hierarchy that requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Our financial instruments that are recorded at fair value are categorized into a three-level hierarchy, which is based upon the priority of the inputs to the valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets (i.e., Level 1) and the lowest priority to unobservable inputs (i.e., Level 3). If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the financial instrument. Financial instruments recorded at fair value are categorized in the fair value hierarchy as follows: • Level 1 : Valuations are based on unadjusted quoted prices in active markets for identical financial instruments that we have the ability to access. • Level 2 : Valuations are based on quoted prices for similar financial instruments, other than quoted prices included in Level 1, in markets that are not active or on inputs that are observable either directly or indirectly for the full term of the financial instrument. • Level 3 : Valuations are based on pricing or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement of the financial instrument. Such inputs may reflect management's own assumptions about the assumptions a market participant would use in pricing the financial instrument. We review our fair value hierarchy categorizations on a quarterly basis at which time the classification of certain financial instruments may change if the input observations have changed. Transfers between levels, if any, are recorded as of the beginning of the reporting period. To determine the fair value of the majority of our investments, we utilize prices obtained from independent, nationally recognized pricing services. We obtain one price for each security. When the pricing services cannot provide a determination of fair value for a specific security, we obtain non-binding price quotes from broker-dealers with whom we have had several years experience and who have demonstrated knowledge of the subject security. We request and utilize one broker quote per security. In order to determine the proper classification in the fair value hierarchy for each security where the price is obtained from an independent pricing service, we obtain and evaluate the vendors' pricing procedures and inputs used to price the security, which include unadjusted quoted market prices for identical securities, such as a New York Stock Exchange closing price, and quoted prices for identical securities in markets that are not active. For fixed maturity securities, an evaluation of interest rates and yield curves observable at commonly quoted intervals, volatility, prepayment speeds, credit risks and default rates may also be performed. We have determined that these processes and inputs result in fair values and classifications consistent with the applicable accounting guidance on fair value measurements. When possible, we use quoted market prices to determine the fair value of fixed maturities, equity securities, trading securities and short-term investments. When quoted market prices do not exist, we base estimates of fair value on market information obtained from independent pricing services and brokers or on valuation techniques that are both unobservable and significant to the overall fair value measurement of the financial instrument. Such inputs may reflect management's own assumptions about the assumptions a market participant would use in pricing the financial instrument. Our valuation techniques are discussed in more detail throughout this section. The fair value of our mortgage loans is determined by modeling performed by us based on the stated principal and coupon payments provided for in the loan agreements. These cash flows are then discounted using an appropriate risk-adjusted discount rate to determine the security's fair value, which is a Level 3 fair value measurement. The fair value of our policy loans is equivalent to carrying value, which is a reasonable estimate of fair value and is classified as Level 2. We do not make policy loans for amounts in excess of the cash surrender value of the related policy. In all instances, the policy loans are fully collateralized by the related liability for future policy benefits for traditional insurance policies or by the policyholders' account balance for non-traditional policies. Our other long-term investments consist primarily of our interests in limited liability partnerships that are recorded on the equity method of accounting. The fair value of the partnerships is obtained from the fund managers, which is based on the fair value of the underlying investments held in the partnerships. In management's opinion, these values represent a reasonable estimate of fair value. We have not adjusted the net asset value provided by the fund managers. For cash and cash equivalents and accrued investment income, carrying value is a reasonable estimate of fair value due to the short-term nature of these financial instruments. The Company formed a rabbi trust in 2014 to fund obligations under the United Fire & Casualty Company Non-qualified Deferred Compensation Plan and United Fire Group Supplemental Executive Retirement and Deferral Plan (collectively, the "Executive Retirement Plans"). Within the rabbi trust, corporate-owned life insurance ("COLI") policies are utilized as an investment vehicle and source of funding for the Company's Executive Retirement Plans. The COLI policies invest in mutual funds, which are priced daily by independent sources. As of September 30, 2017 , the cash surrender value of the COLI policies was $3,759 , which is equal to the fair value measured using Level 2 inputs, based on the underlying assets of the COLI policies, and is included in other assets in the Consolidated Balance Sheets. Policy reserves are developed and recorded for deferred annuities, which is an interest-sensitive product, and income annuities. The fair value of the reserve liability for these annuity products is based upon an estimate of the discounted pretax cash flows that are forecast for the underlying business, which is a Level 3 fair value measurement. We base the discount rate on the current U.S. Treasury spot yield curve, which is then risk-adjusted for nonperformance risk and, for interest-sensitive business and market risk factors. The risk-adjusted discount rate is developed using interest rates that are available in the market and representative of the risks applicable to the underlying business. The fair value of securities that are categorized as Level 1 is based on quoted market prices that are readily and regularly available. We use a market-based approach for valuing all of our Level 2 securities and submit them primarily to a third-party valuation service provider. Any of these securities not valued by this service provider are submitted to another third-party valuation service provider. Both service providers use a market approach to find pricing of similar financial instruments. The market inputs our service providers normally seek to value our securities include the following, listed in approximate order of priority: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. The method and inputs for these securities classified as Level 2 are the same regardless of industry category, credit quality, duration, geographical concentration or economic characteristics. For our mortgage-backed securities, collateralized mortgage obligations and asset-backed securities, our service providers use additional market inputs to value these securities, including the following: new issue data, periodic payment information, monthly payment information, collateral performance and real estate analysis from third parties. Our service providers prioritize inputs based on market conditions, and not all inputs listed are available for use in the valuation process for each security on any given day. At least annually, we review the methodologies and assumptions used by our valuation service providers and verify that they are reasonable and representative of the fair value of the underlying securities held in the investment portfolio. We validate the prices obtained from independent pricing services and brokers prior to their use for reporting purposes by evaluating their reasonableness on a monthly basis. Our validation process includes a review for unusual fluctuations. Unusual fluctuations outside of our expectations are independently corroborated with additional third-party sources that use similar valuation techniques as discussed above. In addition, we also randomly select securities and independently corroborate the valuations obtained from our third-party valuation service providers. In our opinion, the pricing obtained at September 30, 2017 and December 31, 2016 was reasonable. For the three- and nine-month periods ended September 30, 2017 , the change in our available-for-sale securities categorized as Level 1 and Level 2 is the result of investment purchases that were made using funds held in our money market accounts, disposals and the change in unrealized gains on both fixed maturities and equity securities. During the three- and nine-month periods ended September 30, 2017 , there were no securities transferred between Level 1 and Level 2. Securities categorized as Level 3 include holdings in certain private placement fixed maturity and equity securities for which an active market does not currently exist. The fair value of our Level 3 private placement securities is determined by management relying on pricing received from our independent pricing services and brokers consistent with the process to estimate fair value for Level 2 securities. However, securities are categorized as Level 3 if these quotes cannot be corroborated by other market observable data due to the unobservable nature of the brokers’ valuation processes. If pricing cannot be obtained from these sources, which occurs on a limited basis, management will perform a discounted cash flow analysis, using an appropriate risk-adjusted discount rate, on the underlying security to estimate fair value. During the three- and nine-month periods ended September 30, 2017 , there were no securities transferred in or out of Level 3.
Segment Information	Prior to the announcement to sell our subsidiary, United Life Insurance Company, we had two reportable business segments in our operations: property and casualty insurance and life insurance. The property and casualty insurance segment has six domestic locations from which it conducts its business. The life insurance segment operates from our home office in Cedar Rapids, Iowa. Because all of our insurance is sold domestically, we have no revenues from foreign operations. After the announcement of the sale of our life insurance segment, the Company has one reportable segment, the property and casualty insurance segment, which includes all continuing operations. The property and casualty insurance segment profit or loss is consistent with consolidated reporting as disclosed on the Consolidated Statements of Income and Comprehensive Income. We analyze the property and casualty insurance segment results based on profitability (i.e., loss ratios), expenses and return on equity. The Company's property and casualty insurance segment was determined using a management approach to make decisions on operating matters, including allocating resources, assessing performance, determining which products to market and sell, determining distribution networks with insurance agents and monitoring the regulatory environment. The property and casualty insurance segment products have similar economic characteristics and use a similar marketing and distribution strategy with our independent agents. The property and casualty insurance segment geographic concentration did not change after the announcement of the sale of the life insurance segment. We will continue to evaluate our segment on the basis of both statutory accounting principles prescribed or permitted by our states of domicile and GAAP.
Earnings Per Share	Basic earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding during the reporting period. Diluted earnings per share gives effect to all dilutive common shares outstanding during the reporting period. The dilutive shares we consider in our diluted earnings per share calculation relate to our outstanding stock options, restricted stock awards and restricted stock unit awards. We determine the dilutive effect of our outstanding stock options using the "treasury stock" method. Under this method, we assume the exercise of all of the outstanding stock options whose exercise price is less than the weighted-average market value of our common stock during the reporting period. This method also assumes that the proceeds from the hypothetical stock option exercises are used to repurchase shares of our common stock at the weighted-average market value of the stock during the reporting period. The net of the assumed stock options exercised and assumed common shares repurchased represents the number of dilutive common shares, which we add to the denominator of the earnings per share calculation.

Maturities	The amortized cost and fair value of held-to-maturity, available-for-sale and trading fixed maturity securities at September 30, 2017 , by contractual maturity, are shown in the following tables. The first table includes consolidated investments from both continuing and discontinued operations. The second and third tables separate maturities into continuing and discontinued operations. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Asset-backed securities, mortgage-backed securities and collateralized mortgage obligations may be subject to prepayment risk and are therefore not categorized by contractual maturity.
