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 through a network of independent agencies. Our insurance company subsidiaries are licensed as property and casualty insurers in 50 states and the District of Columbia. 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 for the year ended December 31, 2020, including certain financial statement footnote disclosures, is not required by the rules and regulations of the SEC for interim financial reporting and has 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; loss settlement expenses; and pension and post-retirement 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, 2020. Segment Information Our property and casualty insurance business is reported as one business segment. The property and casualty insurance business 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 business results based on profitability (i.e., loss ratios), expenses and return on equity. The Company's property and casualty insurance business 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 business products have similar economic characteristics and use a similar marketing and distribution strategy with our independent agents. We will continue to evaluate our operations on the basis of both statutory accounting principles prescribed or permitted by our states of domicile and GAAP. Lloyd's Syndicates On January 1, 2021, the Company became a member of Lloyd's of London ("Lloyd's"). As a member of Lloyd's, the Company is required to maintain capital at Lloyd's, referred to as Funds at Lloyd's ("FAL"), to support underwriting of property and casualty and reinsurance business by Syndicate 1492, Syndicate 1729, Syndicate 1969, Syndicate 1971 and Syndicate 4747. At June 30, 2021, the Company's FAL investments were comprised of cash of $21,331 on deposit with Lloyd's in order to satisfy these FAL requirements. Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash, money market accounts, cash on deposit and held by Lloyd's and non-negotiable certificates of deposit with original maturities of three months or less. 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, 2021. Total Recorded asset at beginning of period $ 87,094 Underwriting costs deferred 108,464 Amortization of deferred policy acquisition costs (99,272) Recorded asset at June 30, 2021 $ 96,286 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. Other Intangible Assets Our other intangible assets, which consist primarily of agency relationships, trade names, state insurance licenses, and software, are being amortized using the straight-line method over periods ranging from two years to 15 years, with the exception of state insurance licenses, which are indefinite-lived and not amortized. Long Term Debt The Company executed a private placement debt transaction on December 15, 2020 between United Fire & Casualty Company ("UF&C"), and Federated Mutual Insurance Company, a mutual insurance company domiciled in Minnesota ("Federated Mutual"), and Federated Life Insurance Company, an insurance company domiciled in Minnesota ("Federated Life” and, together with Federated Mutual, the "Note Purchasers"). UF&C sold an aggregate principal amount of $50,000 of notes due 2040 to the Note Purchasers. One note with a principal amount of $35,000 was issued to Federated Mutual and one note with a principal amount of $15,000 was issued to Federated Life subject to the terms of their respective notes. The notes are presented as a long term debt liability in the Consolidated Balance Sheets and as a financing activity in the Consolidated Statement of Cash Flows. Interest payments under the surplus notes are paid quarterly on March 15, June 15, September 15 and December 15 of each year (each such date, an "Interest Payment Date"). The interest rate will equal the rate that corresponds to the A.M. Best Co. (or its successor’s) financial strength rating for members of the United Fire & Casualty Pooled Group as of the applicable Interest Payment Date. For the six-month period ended June 30, 2021, interest totaled $1,594 and is included in accrued expenses and other liabilities in the Consolidated Balance Sheets and as Interest expense in the Consolidated Statements of Income and Comprehensive Income. Payment of interest is subject to approval by the Iowa Insurance Division. Income Taxes On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, permits net operating loss ("NOL") carryovers and carrybacks to offset 100 percent of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The Company has considered the implications of the CARES Act on its tax provision. As of June 30, 2021, there was no income tax benefit as the result of the CARES Act. As of June 30, 2020, there was an income tax benefit of $11,095 as the result of the CARES Act. 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 consolidated federal income tax expense of $6,524 for the six-month period ended June 30, 2021 compared to income tax benefit of $34,189 during the same period of 2020. Our effective tax rate for 2021 and 2020 is different than the federal statutory rate of 21 percent, due principally to the net effect of tax-exempt municipal bond interest income. Our effective tax rate for 2020 is also different than the federal statutory rate of 21 percent, due principally to the impact of the provisions of the CARES Act. 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 this 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 not recognize any liability for unrecognized tax benefits at June 30, 2021 or December 31, 2020. 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. For the six-month periods ended June 30, 2021 and 2020, we made payments for income taxes totalin g $29 a nd $35, respectively. We did not receive a tax refund during the six-month periods ended June 30, 2021 and 2020. 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 2017. Leases The Company determines if a contract contains a lease at inception of the contract. The Company's inventory of leases consists of operating leases which are recorded as a lease obligation liability disclosed in the "Accrued expenses and other liabilities" line on the Consolidated Balance Sheets and as a lease right-of-use asset disclosed in the "Other assets" line on the Consolidated Balance Sheets. The Company's operating leases consist of office space, vehicles, computer equipment and office equipment. The lease right-of-use asset represents the Company's right to use each underlying asset for the lease term and the lease obligation liability represents the Company's obligation over the lease term. The Company's lease obligation is recorded at the present value of the lease payments based on the term of the applied lease. Short-term leases of 12 months or less are recorded on the Consolidated Balance Sheets and lease payments are recognized on the Consolidated Statements of Income and Comprehensive Income. For more information on leases refer to Note 10 "Leases." Variable Interest Entities The Company and certain related parties are equity investors in one investment which the Company determined is a variable interest entity ("VIE") as a result of participation in the risks and rewards of the VIE based on the objectives and strategies of the VIE. The VIE is a limited liability company that primarily invests in commercial real estate. The Company and certain related parties are not the primary beneficiary largely due to their inability to influence management or direct the activities that most significantly impact the VIE's economic performance. Based on these facts and circumstances, the Company has a variable interest in the VIE, but has not consolidated the VIE's financial results as it is not the primary beneficiary. The Company's investment is reported in other long-term investments in the Consolidated Balance Sheets and accounted for under the equity method of accounting. The fair value of the VIE at June 30, 2021 was $3,371 and there are no future funding commitments. Credit Losses The Company recognizes credit losses for our available-for-sale fixed-maturity portfolio, reinsurance receivables, mortgage loans and premium receivables by setting up allowances which are remeasured each reporting period and recorded in the Consolidated Statements of Income and Comprehensive Income. For our available-for-sale fixed-maturity portfolio an allowance for credit losses is recorded net of available-for-sale fixed maturities in the Consolidated Balance Sheets and a corresponding credit loss recognized as a realized loss or gain in the Consolidated Statements of Income and Comprehensive Income. The Company determines if an allowance for credit losses is recorded based on a number of factors including the current economic conditions, management's expectations of future economic conditions and performance indicators, such as market value vs. amortized cost, investment spreads widening or contracting, rating actions, payment and default history. For more information on credit losses and the allowance for credit losses for available-for-sale fixed-maturity portfolio, see Note 2 "Summary of Investments." An allowance for mortgage loan losses is established based on historical loss information of the collective pool of the Company's commercial mortgage loan investments which have similar risk characteristics. To calculate the allowance for mortgage loan losses, the Company starts with historical loan experience to predict the future expected losses and then layers on a market-linked adjustment. On a quarterly basis, quantitative credit risk metrics, including for example, cash-flows, rent rolls and financial statements are reviewed for each loan to determine if it is performing in line with its expectations. This allowance is presented as a separate line in the Consolidated Balance Sheets beneath the asset value as well as presented net and recorded through "Net realized investment gains (losses)" in the Consolidated Statements of Income and Comprehensive Income. For more information on credit losses and the allowance for credit losses for our investment in mortgage loans see Note 3 "Fair Value of Financial Instruments." For reinsurance receivables, the Company's model estimates expected credit loss by multiplying the exposure at default by both the probability of default and loss given default ("LGD"). The LGD is estimated by the rating of the reinsurer, historical relationship with UFG, existence of letters of credit and known regulation the Company may be held accountable for. The ultimate LGD percentage is estimated after considering Moody’s experience with unsecured year 1 bond recovery rates from 1983-2017. The allowance calculated as of June 30, 2021 is recorded through the line "Reinsurance receivables and recoverables" in the Consolidated Balance Sheets and through the line "Other underwriting expenses" in the Consolidated Statements of Income and Other Comprehensive Income. As of June 30, 2021, the Company had a credit loss allowance for reinsurance receivable s of $126. Rollforward of credit loss allowance for reinsurance receivable: As of June 30, 2021 Beginning balance, January 1, 2021 $ 190 Current-period provision for expected credit losses — Recoveries of amounts previously written off, if any (64) Ending balance of the allowance for reinsurance receivable, June 30, 2021 $ 126 With respect to premiums receivable, the Company utilizes an aging method to estimate credit losses. An allowance for doubtful accounts is based on a periodic evaluation of the aging and collectability of amounts due from agents and policyholders. "Premiums receivable" are presented in the Consolidated Balance Sheets net of an estimated allowance for doubtful accounts and recorded through "Other underwriting expenses" in the Consolidated Statements of Income and Comprehensive Income. COVID-19 Pandemic The COVID-19 pandemic caused significant financial market volatility, economic uncertainty and interruptions to normal business activities. As of the date of this report, we expect the effect of the COVID-19 pandemic on claims currently under our coverages to be manageable, based on the information presently available. However, the effects of the COVID-19 pandemic, including the emergence of variant strains, continue to evolve and we cannot predict the extent to which our business, results of operations, financial condition, liquidity, capital position, the value of investments we hold in our investment portfolio, premiums and the demand for our products and our ability to collect premiums or requirement to return premiums to our policyholders, will ultimately be impacted. Additionally, if established written contract policy exclusions of business interruption coverage for losses attributable to the COVID-19 pandemic are voided or changed through legislation, regulations or interpretations by the courts, such changes have the potential to materially increase claims, losses and legal expenses which may impact our business, financial condition, results of operations or liquidity. See further discussion in Item 2, Management's Discussion and Analysis of Financial Condition and Results of Operations. 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 2021 Defined Benefit Plans - Disclosures In August 2018, the FASB issued new guidance which modifies the disclosure requirements for employers that sponsor defined benefit pension and postretirement plans. The new guidance removes the requirement for disclosing the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit costs in the next year and the sensitivity of postretirement health plans to one-percentage-point changes in medical trend rates. The new guidance is effective for annual periods beginning after December 15, 2020. The Company adopted the new guidance as of January 1, 2021. The new guidance modifies disclosures, but will not have an impact on the Company's financial position and results of operations.

Fair Value of Financial Instrum

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. 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. In order to determine the proper classification in the fair value hierarchy, 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 mortgage loan portfolio consists entirely of commercial mortgage loans. The fair value of our mortgage loans is determined by modeling performed by our third party fund manager 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. 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 Supplemental Executive Retirement and Deferral Plan (the "Executive Retirement Plan"). 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 Plan. The COLI policies invest in mutual funds, which are priced daily by independent sources. As of June 30, 2021, the cash surrender value of the COLI policies was $9,567 , which is equal to the fair value measured using Level 2 inputs, based on the underlying assets of the COLI policie s, and is included in other assets in the Consolidated Balance Sheets. Our long-term debt is not carried in the Consolidated Balance Sheet at fair value.

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. In addition, on a quarterly basis, we also test all securities in the portfolio and independently corroborate the valuations obtained from our third-party valuation service providers. Quarterly, we also perform deep dive analysis of the pricing method used by our third-party valuation service provider by selecting a random sample of securities by asset class and reviewing methodologies. In our opinion, the pricing obtained at June 30, 2021 and December 31, 2020 was reasonable. For the three- and six-month periods ended June 30, 2021, 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. 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.

As of June 30, 2021, all loan receivables were current, with no delinquencies. The commercial mortgage loans originate with an initial loan-to-value ratio to provide sufficient collateral to absorb losses should a loan be required to foreclose. Mortgage loans are evaluated on a quarterly basis for impairment on an individual basis through a monitoring process and review of key credit indicators, such as economic trends, delinquency rates, property valuations, occupancy and rental rates and loan-to-value ratios. A loan is considered impaired when the Company believes it will not collect the contractual principal and interest set forth in the contractual terms of the loan. An internal grade is assigned to each mortgage loan, with a grade of 1 being the highest and least likely for an impairment and the lowest rating of 7 being the most likely for an impairment. An allowance for mortgage loan losses is established on each loan recognizing a loss for amounts which we believe will not be collected according to the contractual terms of the respective loan agreement. As of June 30, 2021, the Company had an allowance for mortgage loan losses of $76, summarized in the following rollforward: Rollforward of allowance for mortgage loan losses: As of June 30, 2021 Beginning balance, January 1, 2021 $ 76 Current-period provision for expected credit losses — Ending balance of the allowance for mortgage loan losses, June 30, 2021 $ 76

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. 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 June 30, 2021 and December 31, 2020 (net of reinsurance amounts): June 30, 2021 December 31, 2020 Gross liability for losses and loss settlement expenses $ 1,578,131 $ 1,421,754 Ceded losses and loss settlement expenses (131,843) (68,536) Net liability for losses and loss settlement expenses $ 1,446,288 $ 1,353,218 Losses and loss settlement expenses incurred Current year $ 373,561 $ 887,119 Prior years (15,024) (17,652) Total incurred $ 358,537 $ 869,467 Losses and loss settlement expense payments Current year $ 116,385 $ 354,635 Prior years 234,863 421,762 Total paid $ 351,248 $ 776,397 Net liability for losses and loss settlement expenses $ 1,453,577 $ 1,446,288 Ceded loss and loss settlement expenses 114,876 131,843 Gross liability for losses and loss settlement expenses $ 1,568,453 $ 1,578,131 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 monetary impact of any individual factor on the development of reserves. 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. Reserve Development The significant drivers of the favorable reserve development in the six-month period ended June 30, 2021 were the commercial automobile and workers' compensation lines of business, partially offset by unfavorable development in commercial liability. All other lines of insurance, in total, contributed favorable development during the quarter. The favorable development for commercial automobile was from loss adjustment expenses ("LAE") where reductions in reserves were more than sufficient to offset paid LAE. Workers' compensation favorable development came from both loss and loss adjustment expense. Reserve reductions for both items were more than sufficient to offset payments. The adverse development for commercial liability is attributable to paid loss which was greater than the reductions of unpaid claim reserves. Paid LAE was more than offset by reductions of reserves for unpaid loss adjustment expense.

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. In May 2021, the Registrant's shareholders approved an additional 650,000 shares of UFG common stock issuable at any time and from time to time pursuant to the Stock Plan, and among other amendments, renamed such plan as the United Fire Group, Inc. 2021 Stock and Incentive Plan (as amended, the "Stock Plan"). At June 30, 2021, there were 1,234,701 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 United Fire. 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. Options granted prior to March 2017 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. Options granted after March 2017 vest and are exercisable in installments of 33.3 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 UFG's common stock on the date of the grant. Restricted stock units fully vest after three years or five years from the date of grant, 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 Six Months Ended June 30, 2021 From Inception to June 30, 2021 Beginning balance 700,680 1,900,000 Additional shares authorized 650,000 2,150,000 Number of awards granted (160,357) (3,449,256) Number of awards forfeited or expired 44,378 633,957 Ending balance 1,234,701 1,234,701 Number of option awards exercised 7,884 1,481,973 Number of unrestricted stock awards granted — 10,090 Number of restricted stock awards vested 52,302 216,680 Non-Qualified Non-Employee Director Stock Plan The United Fire Group, Inc.

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 June 30, 2021 and 2020: Three Months Ended June 30, (In Thousands, Except Share Data) 2021 2020 Basic Diluted Basic Diluted Net income $ 13,750 $ 13,750 $ 5,960 $ 5,960 Weighted-average common shares outstanding 25,109,048 25,109,048 25,024,855 25,024,855 Add dilutive effect of restricted stock unit awards — 219,700 — 213,203 Add dilutive effect of stock options — 88,120 — 17,546 Weighted-average common shares outstanding 25,109,048 25,416,868 25,024,855 25,255,604 Earnings per common share $ 0.55 $ 0.54 $ 0.24 $ 0.24 Awards excluded from diluted earnings per share calculation (1) — 515,984 — 815,279 (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]
Debt	DEBT Long Term Debt The Company executed a private placement debt transaction on December 15, 2020 between UF&C, and Federated Mutual and Federated Life. UF&C sold an aggregate principal amount of $50,000 of notes due 2040 to the Note Purchasers. One note with a principal amount of $35,000 was issued to Federated Mutual and one note with a principal amount of $15,000 was issued to Federated Life subject to the terms of their respective notes. Interest payments under the surplus notes will be paid quarterly on March 15, June 15, September 15 and December 15 of each year (each such date, an "Interest Payment Date"). The interest rate will equal the rate that corresponds to the A.M. Best Co. (or its successor’s) financial strength rating for members of the United Fire & Casualty Pooled Group as of the applicable Interest Payment Date, as set forth in the table below. For the six-month period ended June 30, 2021, interest expense totaled $1,594. Payment of interest is subject to approval by the Iowa Insurance Division. A.M. Best Co. Financial Strength Rating Applicable Interest Rate A+ 5.875% A 6.375% A- 6.875% B++ (or lower) 7.375% Credit Facilities On March 31, 2020, UF&C, a wholly owned subsidiary of the Company, entered into a credit agreement (the "Credit Agreement") with Wells Fargo Bank, National Association ("Wells Fargo"), as administrative agent (the "Administrative Agent"), issuing lender, swing-line lender and lender, and the other lenders from time to time party thereto (collectively with Wells Fargo, the "Lenders"), providing for a $50,000 revolving credit facility, which includes a $20,000 letter of credit sub-facility and a $5,000 swing-line loan for working capital and other general corporate purposes. The Credit Agreement is provided by the Lenders on an unsecured basis, and UF&C has the option to increase the Credit Agreement by $100,000 if agreed to by the Lenders providing such incremental facility. The Credit Agreement includes customary events of default, including default in payments of principals, default in payment of other indebtedness, change of control and voluntary and involuntary insolvency proceedings, the occurrence of which would allow the Lenders to accelerate payment of all amounts outstanding thereunder and terminate any further commitments to lend. The entry into the Credit Agreement was completed as part of the Company’s regular course of financial planning and was not initiated as a result of market conditions resulting from the COVID-19 pandemic. There was no outstanding balance on the Credit Agreement at June 30, 2021 and 2020, respectively. For the six-month periods ended June 30, 2021 and 2020, we did not incur any interest expense related to the credit facility. We were in compliance with all covenants under the Credit Agreement at June 30, 2021.

Leases [Abstract]
Leases	LEASES The Company has operating leases consisting of office space, vehicle leases, computer equipment, and office equipment. Lease terms and options vary in the Company's operating leases dependent upon the underlying leased asset. We exclude options to extend or terminate a lease from our recognition as part of our right-of-use assets and lease liabilities until those options are known and/or executed, as we typically do not exercise options to purchase the underlying leased asset. As of June 30, 2021, we have leases with remaining terms of one year to seven years, some of which may include no options for renewal and others with options to extend the lease terms from six months to five years. The components of our operating leases were as follows for the three- and six-month periods ended June 30, 2021 and 2020: Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 Components of lease expense: Operating lease expense $ 1,767 $ 1,926 $ 3,549 $ 3,956 Less sublease income 53 63 107 186 Net lease expense 1,714 1,863 3,442 3,770 Cash flows information related to leases: Operating cash outflow from operating leases 1,731 1,829 3,478 3,469

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 for the year ended December 31, 2020, including certain financial statement footnote disclosures, is not required by the rules and regulations of the SEC for interim financial reporting and has 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; loss settlement expenses; and pension and post-retirement benefit obligations.
Reclassification	Certain prior year amounts have been reclassified to conform to the current year presentation.
Segment Information	Our property and casualty insurance business is reported as one business segment. The property and casualty insurance business 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 business results based on profitability (i.e., loss ratios), expenses and return on equity. The Company's property and casualty insurance business 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 business products have similar economic characteristics and use a similar marketing and distribution strategy with our independent agents. We will continue to evaluate our operations on the basis of both statutory accounting principles prescribed or permitted by our states of domicile and GAAP.
Cash and Cash Equivalents	For purposes of reporting cash flows, cash and cash equivalents include cash, money market accounts, cash on deposit and held by Lloyd's and non-negotiable certificates of deposit with original maturities of three months or less.
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.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.
Other Intangible Assets	Our other intangible assets, which consist primarily of agency relationships, trade names, state insurance licenses, and software, are being amortized using the straight-line method over periods ranging from two years to 15 years, with the exception of state insurance licenses, which are indefinite-lived and not amortized.
Income Taxes	On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, permits net operating loss ("NOL") carryovers and carrybacks to offset 100 percent of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The Company has considered the implications of the CARES Act on its tax provision. As of June 30, 2021, there was no income tax benefit as the result of the CARES Act. As of June 30, 2020, there was an income tax benefit of $11,095 as the result of the CARES Act. 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 consolidated federal income tax expense of $6,524 for the six-month period ended June 30, 2021 compared to income tax benefit of $34,189 during the same period of 2020. Our effective tax rate for 2021 and 2020 is different than the federal statutory rate of 21 percent, due principally to the net effect of tax-exempt municipal bond interest income. Our effective tax rate for 2020 is also different than the federal statutory rate of 21 percent, due principally to the impact of the provisions of the CARES Act. 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 this 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 not recognize any liability for unrecognized tax benefits at June 30, 2021 or December 31, 2020. 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. For the six-month periods ended June 30, 2021 and 2020, we made payments for income taxes totalin g $29 a nd $35, respectively. We did not receive a tax refund during the six-month periods ended June 30, 2021 and 2020.
Leases	The Company determines if a contract contains a lease at inception of the contract. The Company's inventory of leases consists of operating leases which are recorded as a lease obligation liability disclosed in the "Accrued expenses and other liabilities" line on the Consolidated Balance Sheets and as a lease right-of-use asset disclosed in the "Other assets" line on the Consolidated Balance Sheets. The Company's operating leases consist of office space, vehicles, computer equipment and office equipment. The lease right-of-use asset represents the Company's right to use each underlying asset for the lease term and the lease obligation liability represents the Company's obligation over the lease term. The Company's lease obligation is recorded at the present value of the lease payments based on the term of the applied lease. Short-term leases of 12 months or less are recorded on the Consolidated Balance Sheets and lease payments are recognized on the Consolidated Statements of Income and Comprehensive Income.
Variable Interest Entities	The Company and certain related parties are equity investors in one investment which the Company determined is a variable interest entity ("VIE") as a result of participation in the risks and rewards of the VIE based on the objectives and strategies of the VIE. The VIE is a limited liability company that primarily invests in commercial real estate. The Company and certain related parties are not the primary beneficiary largely due to their inability to influence management or direct the activities that most significantly impact the VIE's economic performance. Based on these facts and circumstances, the Company has a variable interest in the VIE, but has not consolidated the VIE's financial results as it is not the primary beneficiary. The Company's investment is reported in other long-term investments in the Consolidated Balance Sheets and accounted for under the equity method of accounting.
Credit Losses	The Company recognizes credit losses for our available-for-sale fixed-maturity portfolio, reinsurance receivables, mortgage loans and premium receivables by setting up allowances which are remeasured each reporting period and recorded in the Consolidated Statements of Income and Comprehensive Income. For our available-for-sale fixed-maturity portfolio an allowance for credit losses is recorded net of available-for-sale fixed maturities in the Consolidated Balance Sheets and a corresponding credit loss recognized as a realized loss or gain in the Consolidated Statements of Income and Comprehensive Income. The Company determines if an allowance for credit losses is recorded based on a number of factors including the current economic conditions, management's expectations of future economic conditions and performance indicators, such as market value vs. amortized cost, investment spreads widening or contracting, rating actions, payment and default history. For more information on credit losses and the allowance for credit losses for available-for-sale fixed-maturity portfolio, see Note 2 "Summary of Investments." An allowance for mortgage loan losses is established based on historical loss information of the collective pool of the Company's commercial mortgage loan investments which have similar risk characteristics. To calculate the allowance for mortgage loan losses, the Company starts with historical loan experience to predict the future expected losses and then layers on a market-linked adjustment. On a quarterly basis, quantitative credit risk metrics, including for example, cash-flows, rent rolls and financial statements are reviewed for each loan to determine if it is performing in line with its expectations. This allowance is presented as a separate line in the Consolidated Balance Sheets beneath the asset value as well as presented net and recorded through "Net realized investment gains (losses)" in the Consolidated Statements of Income and Comprehensive Income. For more information on credit losses and the allowance for credit losses for our investment in mortgage loans see Note 3 "Fair Value of Financial Instruments."
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 2021 Defined Benefit Plans - Disclosures In August 2018, the FASB issued new guidance which modifies the disclosure requirements for employers that sponsor defined benefit pension and postretirement plans. The new guidance removes the requirement for disclosing the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit costs in the next year and the sensitivity of postretirement health plans to one-percentage-point changes in medical trend rates. The new guidance is effective for annual periods beginning after December 15, 2020. The Company adopted the new guidance as of January 1, 2021. The new guidance modifies disclosures, but will not have an impact on the Company's financial position and results of operations.
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. 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. In order to determine the proper classification in the fair value hierarchy, 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 mortgage loan portfolio consists entirely of commercial mortgage loans. The fair value of our mortgage loans is determined by modeling performed by our third party fund manager 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. 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 Supplemental Executive Retirement and Deferral Plan (the "Executive Retirement Plan"). 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 Plan. The COLI policies invest in mutual funds, which are priced daily by independent sources. As of June 30, 2021, the cash surrender value of the COLI policies was $9,567 , which is equal to the fair value measured using Level 2 inputs, based on the underlying assets of the COLI policie s, and is included in other assets in the Consolidated Balance Sheets. Our long-term debt is not carried in the Consolidated Balance Sheet at fair value. The fair value of our long-term debt is estimated using Level 2 inputs based on quoted prices for similar financial instruments. The fair value is estimated using a discounted cash flows analysis. 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. In addition, on a quarterly basis, we also test all securities in the portfolio and independently corroborate the valuations obtained from our third-party valuation service providers. Quarterly, we also perform deep dive analysis of the pricing method used by our third-party valuation service provider by selecting a random sample of securities by asset class and reviewing methodologies. In our opinion, the pricing obtained at June 30, 2021 and December 31, 2020 was reasonable. For the three- and six-month periods ended June 30, 2021, 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.
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

Schedule of Maturities	The amortized cost and fair value of available-for-sale fixed maturity securities at June 30, 2021, by contractual maturity, are shown in the following tables.
