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. We report our operations in two business segments: property and casualty insurance and life insurance. Our insurance company subsidiaries are licensed as a property and casualty insurer in 43 states and the District of Columbia, and as a life insurer in 37 states. 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. In the preparation of the accompanying unaudited Consolidated Financial Statements, we have 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. 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, 2014 . The review report of Ernst & Young LLP as of June 30, 2015 and for the three- and six-month periods ended June 30, 2015 and 2014 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 six-month periods ended June 30, 2015 and 2014 , we made payments for income taxes totaling $27,216 and $9,115 , respectively. We did no t receive a tax refund during the six-month period ended June 30, 2015 . We received a tax refund of $615 during the six-month period ended June 30, 2014 . For the six-month periods ended June 30, 2015 and 2014 , 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 six-month period ended June 30, 2015 . Property & Casualty Insurance Life Insurance Total Recorded asset at beginning of period $ 72,861 $ 66,858 $ 139,719 Underwriting costs deferred 98,396 2,990 101,386 Amortization of deferred policy acquisition costs (83,458 ) (3,371 ) (86,829 ) Ending unamortized deferred policy acquisition costs $ 87,799 $ 66,477 $ 154,276 Impact of unrealized gains and losses on available-for-sale securities — 4,797 4,797 Recorded asset at June 30, 2015 $ 87,799 $ 71,274 $ 159,073 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. With the completion of the Mercer Insurance Group integration, we determined it was the appropriate time to review our DAC models. After reviewing our DAC model at March 31, 2015, we enhanced our property & casualty insurance segment DAC model by updating our aggregation of certain lines of business in a manner consistent with how the policies are currently being marketed and managed. The impact of these updates to the model resulted in an increase to other underwriting amortization of $149 and an increase to the DAC asset of $2,709 for the six-month period ended June 30, 2015 as compared to what we would have recognized had we not updated our model. 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 $8,586 and $13,383 at June 30, 2015 and December 31, 2014 , 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 expense of $12,667 and $4,937 for the six-month periods ended June 30, 2015 and 2014 , 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 position 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 position will be sustained, the Company will calculate any unrecognized tax benefits and, if necessary, calculate and accrue any related interest and penalties. We did not recognize any liability for unrecognized tax benefits at June 30, 2015 or December 31, 2014 . 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. 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 2009. The Internal Revenue Service is conducting a routine examination of our income tax return for the 2011 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. Recently Issued Accounting Standards Accounting Standards Adopted in 2015 Troubled Debt Restructuring In August 2014, the FASB issued updated guidance on the accounting for creditors who are holding receivables with troubled debt restructuring, specifically related to the classification of certain government guaranteed mortgage loans that are in foreclosure. The objective of this update is to provide greater consistency and transparency by addressing the classification of certain foreclosed mortgage loans guaranteed through government programs. The guidance is effective for interim and annual periods beginning after December 15, 2014. The Company adopted the guidance on January 1, 2015. The adoption of the new guidance had no impact on the Company's financial position or results of operations. Discontinued Operations In April 2014, the FASB issued new guidance on reporting discontinued operations and disclosures of disposals of components of an entity. The new guidance raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning after December 15, 2014. The Company adopted the guidance on January 1, 2015. The adoption of the new guidance had no impact on the Company's financial position or results of operations. Pending Adoption of Accounting Standards Short Duration Contracts In May 2015, the Financial Accounting Standards Board ("FASB") issued guidance on disclosure requirements for short-duration contracts. The new guidance requires additional disclosures about the liability for unpaid loss and loss adjustment expenses and requires disclosure of any information about significant changes in methodologies and assumptions used to calculate the liability. The new guidance is effective for annual periods beginning after December 15, 2015 and interim periods beginning the following year. The Company will adopt the new guidance on January 1, 2016 and is currently evaluating its disclosures for short-duration contracts and the impact on the Company's financial statement disclosures. Other Internal Use Software In April 2015, the FASB issued guidance which clarifies customers' accounting for fees paid for cloud computing arrangements. The new guidance provides guidance to customers about whether a cloud computing arrangement includes a software license or whether the arrangement is considered a service contract. The new guidance is effective for annual and interim periods beginning after December 15, 2015. The Company will adopt the new guidance on January 1, 2016 and is currently evaluating its accounting for cloud computing arrangements and the impact on the Company's financial position and results of operations. Debt Issuance Costs In April 2015, the FASB issued new guidance on the presentation of debt issuance costs. The new guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. The new guidance is effective for annual and interim periods beginning after December 15, 2015. The Company will adopt the new guidance on January 1, 2016. At this point in time, Management does not expect the adoption of the new guidance to have an impact on the Company's financial position or results of operations. Consolidation In February 2015, the FASB issued amendments to the consolidation analysis that a reporting entity performs to determine whether it should consolidate certain legal entities. Specifically, the new guidance modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIE"), eliminates the presumption that a general partner should consolidate a limited partnership and affects the consolidation analysis of reporting entities that have VIE's, particularly those with fee arrangements and related party relationships. The new guidance is effective for annual and interim periods beginning after December 15, 2015. The Company will adopt the new guidance on January 1, 2016 and is currently evaluating the impact on the Company's financial position and results of operations. Going Concern In August 2014, the FASB issued new guidance on the disclosure of uncertainties about an entity's ability to continue as a going concern. The new guidance requires management to evaluate whether there is substantial doubt about the entity's ability to continue as a going concern and, if so, to disclose the fact and what the entity's plans are to alleviate that doubt. The guidance is effective for annual periods ending after December 15, 2015 and interim periods within annual periods beginning after December 15, 2015. The Company will adopt the guidance on January 1, 2016. Management currently does not expect the adoption of the new guidance to have an impact on the Company's financial position or results of operations. Share Based Payments In June 2014, the FASB issued new guidance on the accounting for share based payments when the terms of an award provide that a performance target could be achieved after the requisite service period . The new guidance requires a performance target that affects vesting and that could be achieved after the service period, be treated as a performance condition. The guidance is effective for interim and annual periods beginning after December 15, 2015. The amendments can be applied prospectively or retrospectively and early adoption is permitted. The Company will adopt the guidance on January 1, 2016 and is currently evaluating the impact on the Company's financial position and results of operations. 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 on January 1, 2018 and is currently evaluating the impact on the Company's financial position and results of operations and considering which transition method it will use in implementing the new guidance.

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.

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 $19,987 and $20,928 at June 30, 2015 and December 31, 2014 , 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 $9,360 at June 30, 2015 . Unrealized Appreciation A summary of the changes in net unrealized investment appreciation during the reporting period is as follows: Six Months Ended June 30, 2015 2014 Change in net unrealized investment appreciation Available-for-sale fixed maturities $ (29,009 ) $ 56,861 Available-for-sale equity securities (1,802 ) 9,148 Deferred policy acquisition costs 4,797 (17,921 ) Income tax effect 9,105 (16,831 ) Total change in net unrealized investment appreciation, net of tax $ (16,909 ) $ 31,257 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. 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 at June 30, 2015 and December 31, 2014 . 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 June 30, 2015 , 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 unless otherwise noted, these losses did not warrant the recognition of an OTTI charge at June 30, 2015 or at June 30, 2014 . We believe the unrealized depreciation in value of other securities in our fixed maturity portfolio is primarily attributable to changes in market interest rates and not the credit quality of the issuer. 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 to 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 unless otherwise noted, these losses do not warrant the recognition of an OTTI charge at June 30, 2015 . Our largest unrealized loss greater than 12 months on an individual equity security at June 30, 2015 was $32 . 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 Instruments	6 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. We estimate the fair value of our financial instruments based on relevant market information or by discounting estimated future cash flows at estimated current market discount rates appropriate to the specific asset or liability. 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 are 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. 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, market risk factors.

We use a market-based approach for valuing all of our Level 2 securities except for our mortgage-backed securities, collateralized mortgage obligations and asset-backed 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 a second 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 evaluation process for each security evaluation on any given day. 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. In our opinion, the pricing obtained at June 30, 2015 and December 31, 2014 was reasonable. Unusual fluctuations outside of our expectations are independently corroborated with secondary 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. For the three- and six-month periods ended June 30, 2015 , 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 six-month periods ended June 30, 2015 , 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. The following table provides a summary of the changes in fair value of our Level 3 securities for the three-month period ended June 30, 2015 : States, municipalities and political subdivisions Corporate bonds Asset-backed securities Equities Total Balance at March 31, 2015 $ 519 $ 12,199 $ 1,493 $ 3,978 $ 18,189 Net unrealized losses (1) (14 ) (32 ) (48 ) — (94 ) Disposals (75 ) (223 ) (134 ) — (432 ) Balance at June 30, 2015 $ 430 $ 11,944 $ 1,311 $ 3,978 $ 17,663 (1) Unrealized losses are recorded as a component of comprehensive income.

The fixed maturities reported as disposals relate to the receipt of principal on calls or sinking fund bonds, in accordance with the indentures. Corporate-Owned Life Insurance 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 June 30, 2015 , the cash surrender value of the COLI policies was $ 1,148 , 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.

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, 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 June 30, 2015 , there were 1,390,323 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 vest and are exercisable in installments of 20.0 percent of the number of shares covered by the option award each year from the grant date, unless the Board of Directors authorizes the acceleration of vesting. 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 our common stock on the date of the grant. Restricted stock awards fully vest after 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. All awards are generally granted free of charge to the eligible employees of UFG as designated by the Board of Directors. The activity in the Stock Plan is displayed in the following table: Authorized Shares Available for Future Award Grants Six Months Ended June 30, 2015 From Inception to June 30, 2015 Beginning balance 1,646,947 1,900,000 Additional shares authorized — 1,500,000 Number of awards granted (363,774 ) (2,360,283 ) Number of awards forfeited or expired 107,150 350,606 Ending balance 1,390,323 1,390,323 Number of option awards exercised 54,505 522,068 Number of unrestricted stock awards granted 920 6,200 Number of restricted stock awards vested — 18,576 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 June 30, 2015 , we had 69,938 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 Director 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 Director Plan). The Board of Directors may also take any action it deems necessary and appropriate for the administration of the Director Plan.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION We have two reportable business segments in our operations: property and casualty insurance and life insurance. The property and casualty insurance segment has seven 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. We evaluate the two segments on the basis of both statutory accounting principles prescribed or permitted by our states of domicile and GAAP. We analyze results based on profitability (i.e., loss ratios), expenses, and return on equity. The basis we use to determine and analyze segments and to measure segment profit or loss have not changed from that reported in our Annual Report on Form 10-K for the year ended December 31, 2014 . We have reconciled the amounts in the following table for the three-month periods ended June 30, 2015 and 2014 to the amounts reported in our unaudited Consolidated Financial Statements, adjusting for intersegment eliminations.

Earnings Per Common Share

Earnings Per Common Share	6 Months Ended

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 and restricted stock 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.

Debt Disclosure [Abstract]
Credit Facility	CREDIT FACILITY In December 2011, UFG entered into a credit agreement with a syndicate of financial institutions as lenders. KeyBank National Association is the administrative agent, lead arranger, sole book runner, swingline lender, and letter of credit issuer, and Bankers Trust Company is the syndication agent. The four -year credit agreement provides for a $100,000 unsecured revolving credit facility that includes a $20,000 letter of credit subfacility and a swingline subfacility of up to $5,000 . On June 4, 2013, United Fire & Casualty Company, United Fire Group, Inc. and the syndicated lenders entered into an Assignment, Joinder, Assumption, and Release Agreement (the "Joinder Agreement") transferring the obligations under the credit agreement from United Fire & Casualty Company to United Fire Group, Inc. Effective with the execution of the Joinder Agreement, United Fire & Casualty Company was released from any further obligations under the credit agreement. During the term of this credit agreement, we have the right to increase the total credit facility from $100,000 up to $125,000 if no event of default has occurred and is continuing and certain other conditions are satisfied. The credit facility is available for general corporate purposes, including working capital, acquisitions and liquidity purposes. Any principal outstanding under the credit facility is due in full at maturity, on December 22, 2015. The interest rate is based on our monthly choice of either a base rate or the London Interbank Offered Rate ("LIBOR") plus, in each case, a calculated margin amount. A commitment fee on each lender's unused commitment under the credit facility is also payable quarterly. The credit agreement contains customary representations, covenants and events of default, including certain covenants that limit or restrict our ability to engage in certain activities. Subject to certain exceptions, these activities include restricting our ability to sell or transfer assets or enter into a merger or consolidate with another company, grant certain types of security interests, incur certain types of liens, impose restrictions on subsidiary dividends, enter into leaseback transactions, or incur certain indebtedness. The credit agreement contains certain financial covenants, including covenants that require us to maintain a minimum consolidated net worth, a debt to capitalization ratio and minimum shareholders' equity. There was no outstanding balance on the credit facility at June 30, 2015 and 2014 . For the six-month periods ended June 30, 2015 and 2014 , we did not incur any interest expense related to this credit facility. We were in compliance with all covenants for the credit agreement at June 30, 2015 .

Nature of Operations and Basis of Presentation (Policies)	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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.
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)	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. With the completion of the Mercer Insurance Group integration, we determined it was the appropriate time to review our DAC models. After reviewing our DAC model at March 31, 2015, we enhanced our property & casualty insurance segment DAC model by updating our aggregation of certain lines of business in a manner consistent with how the policies are currently being marketed and managed. The impact of these updates to the model resulted in an increase to other underwriting amortization of $149 and an increase to the DAC asset of $2,709 for the six-month period ended June 30, 2015 as compared to what we would have recognized had we not updated our model. 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. 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.
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 expense of $12,667 and $4,937 for the six-month periods ended June 30, 2015 and 2014 , 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 position 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 position will be sustained, the Company will calculate any unrecognized tax benefits and, if necessary, calculate and accrue any related interest and penalties. We did not recognize any liability for unrecognized tax benefits at June 30, 2015 or December 31, 2014 . 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. 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 2009. The Internal Revenue Service is conducting a routine examination of our income tax return for the 2011 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.
Recently Issued Accounting Standards	Accounting Standards Adopted in 2015 Troubled Debt Restructuring In August 2014, the FASB issued updated guidance on the accounting for creditors who are holding receivables with troubled debt restructuring, specifically related to the classification of certain government guaranteed mortgage loans that are in foreclosure. The objective of this update is to provide greater consistency and transparency by addressing the classification of certain foreclosed mortgage loans guaranteed through government programs. The guidance is effective for interim and annual periods beginning after December 15, 2014. The Company adopted the guidance on January 1, 2015. The adoption of the new guidance had no impact on the Company's financial position or results of operations. Discontinued Operations In April 2014, the FASB issued new guidance on reporting discontinued operations and disclosures of disposals of components of an entity. The new guidance raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It is effective for annual periods beginning after December 15, 2014. The Company adopted the guidance on January 1, 2015. The adoption of the new guidance had no impact on the Company's financial position or results of operations. Pending Adoption of Accounting Standards Short Duration Contracts In May 2015, the Financial Accounting Standards Board ("FASB") issued guidance on disclosure requirements for short-duration contracts. The new guidance requires additional disclosures about the liability for unpaid loss and loss adjustment expenses and requires disclosure of any information about significant changes in methodologies and assumptions used to calculate the liability. The new guidance is effective for annual periods beginning after December 15, 2015 and interim periods beginning the following year. The Company will adopt the new guidance on January 1, 2016 and is currently evaluating its disclosures for short-duration contracts and the impact on the Company's financial statement disclosures. Other Internal Use Software In April 2015, the FASB issued guidance which clarifies customers' accounting for fees paid for cloud computing arrangements. The new guidance provides guidance to customers about whether a cloud computing arrangement includes a software license or whether the arrangement is considered a service contract. The new guidance is effective for annual and interim periods beginning after December 15, 2015. The Company will adopt the new guidance on January 1, 2016 and is currently evaluating its accounting for cloud computing arrangements and the impact on the Company's financial position and results of operations. Debt Issuance Costs In April 2015, the FASB issued new guidance on the presentation of debt issuance costs. The new guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. The new guidance is effective for annual and interim periods beginning after December 15, 2015. The Company will adopt the new guidance on January 1, 2016. At this point in time, Management does not expect the adoption of the new guidance to have an impact on the Company's financial position or results of operations. Consolidation In February 2015, the FASB issued amendments to the consolidation analysis that a reporting entity performs to determine whether it should consolidate certain legal entities. Specifically, the new guidance modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIE"), eliminates the presumption that a general partner should consolidate a limited partnership and affects the consolidation analysis of reporting entities that have VIE's, particularly those with fee arrangements and related party relationships. The new guidance is effective for annual and interim periods beginning after December 15, 2015. The Company will adopt the new guidance on January 1, 2016 and is currently evaluating the impact on the Company's financial position and results of operations. Going Concern In August 2014, the FASB issued new guidance on the disclosure of uncertainties about an entity's ability to continue as a going concern. The new guidance requires management to evaluate whether there is substantial doubt about the entity's ability to continue as a going concern and, if so, to disclose the fact and what the entity's plans are to alleviate that doubt. The guidance is effective for annual periods ending after December 15, 2015 and interim periods within annual periods beginning after December 15, 2015. The Company will adopt the guidance on January 1, 2016. Management currently does not expect the adoption of the new guidance to have an impact on the Company's financial position or results of operations. Share Based Payments In June 2014, the FASB issued new guidance on the accounting for share based payments when the terms of an award provide that a performance target could be achieved after the requisite service period . The new guidance requires a performance target that affects vesting and that could be achieved after the service period, be treated as a performance condition. The guidance is effective for interim and annual periods beginning after December 15, 2015. The amendments can be applied prospectively or retrospectively and early adoption is permitted. The Company will adopt the guidance on January 1, 2016 and is currently evaluating the impact on the Company's financial position and results of operations. 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 on January 1, 2018 and is currently evaluating the impact on the Company's financial position and results of operations and considering which transition method it will use in implementing the new guidance.
