Organization, Consolidation and Presentation of Financial Statements [Abstract]

Principles of Consolidation

The accompanying Consolidated Financial Statements include United Fire and its wholly owned subsidiaries: United Fire & Casualty Company, United Real Estate Holdings, LLC, Addison Insurance Company, Lafayette Insurance Company, United Fire & Indemnity Company, United Fire Lloyds, UFG Specialty Insurance Company, Financial Pacific Insurance Company, Franklin Insurance Company, Mercer Insurance Company, Mercer Insurance Company of New Jersey, Inc, McIntyre Cedar UK Limited, Mercer Insurance Company and McIntyre Cedar Corporate Member LLP.

United Fire Lloyds, an affiliate of United Fire & Indemnity Company, is organized as a Texas Lloyds plan, which is an aggregation of underwriters who, under a common name, engage in the business of insurance through a corporate attorney-in-fact. United Fire Lloyds is financially and operationally controlled by United Fire & Indemnity Company, its corporate attorney-in-fact, pursuant to three types of agreements: trust agreements between United Fire & Indemnity Company and certain individuals who agree to serve as trustees; articles of agreement among the trustees who agree to act as underwriters to establish how the Lloyds plan will be operated; and powers of attorney from each of the underwriters appointing a corporate attorney-in-fact, who is authorized to operate the Lloyds plan. Because United Fire & Indemnity Company can name the trustees, the Lloyds plan is perpetual, subject only to United Fire & Indemnity Company's desire to terminate it.

United Fire & Indemnity Company provides all of the statutory capital necessary for the formation of the Lloyds plan by contributing capital to each of the trustees. The trust agreements require the trustees to become underwriters of the Lloyds plan, to contribute the capital to the Lloyds plan, to sign the articles of agreement and to appoint the attorney-in-fact. The trust agreements also require the trustees to pay to United Fire & Indemnity Company all of the profits and benefits received by the trustees as underwriters of the Lloyds plan, which means that United Fire & Indemnity Company has the right to receive 100 percent of the gains and profits from the Lloyds plan. The trustees serve at the pleasure of United Fire & Indemnity Company, which may remove a trustee and replace that trustee at any time. Termination of a trustee must be accompanied by the resignation of the trustee as an underwriter, so that the trustee can obtain the capital contribution from the Lloyds plan to reimburse United Fire & Indemnity Company. By retaining the ability to terminate trustees, United Fire & Indemnity Company possesses the ability to name and remove the underwriters.

United Real Estate Holdings, LLC, formed in 2013, is a wholly owned subsidiary of United Fire & Casualty Company and is organized as an Iowa limited liability corporation, an unincorporated association formed for the purpose of holding United Fire & Casualty Company's ownership in commercial real estate.

Basis of Presentation

The accompanying Consolidated Financial Statements have been prepared on the basis of U.S. generally accepted accounting principles ("GAAP"), which differ in some respects from those followed in preparing our statutory reports to insurance regulatory authorities. Our stand-alone and consolidated subsidiary financial statements submitted to insurance regulatory authorities are presented on the basis of accounting practices prescribed or permitted by the insurance departments of the states in which we are domiciled ("statutory accounting principles").

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; goodwill impairment; losses and loss settlement expenses; and pension benefit obligations.

Property and Casualty Insurance Business

Premiums written are deferred and recorded as earned premium on a daily pro rata basis over the terms of the respective policies. Unearned premium reserves are established for the portion of premiums written applicable to the unexpired term of insurance policies in force.

Premiums Receivable

Premiums receivable are presented net of an estimated allowance for doubtful accounts, which is based on a periodic evaluation of the aging and collectability of amounts due from agents and policyholders.

Loss and Loss Settlement Expense Reserves

To establish loss and loss settlement expense reserves, we make estimates and assumptions about the future development of claims. Actual results could differ materially from those estimates, which are subjective, complex and inherently uncertain. When we establish and adjust reserves, we do so given our knowledge at the time of the circumstances and facts of known claims. To the extent that we have overestimated or underestimated our loss and loss settlement expense reserves, we adjust the reserves in the period in which such adjustment is determined.

We record our best estimate of reserves for claim litigation that arises in the ordinary course of business.

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 continually evaluate our operations on the basis of both statutory accounting principles prescribed or permitted by our states of domicile and GAAP.

Reinsurance

Net premiums earned and losses and loss settlement expenses are reported net of reinsurance ceded. Ceded insurance business is accounted for on a basis consistent with the original policies issued and the terms of the reinsurance contracts.

Investments

Investments in fixed maturities includes bonds. Our investments in available-for-sale fixed maturities and trading securities are recorded at fair value. Changes in unrealized appreciation and depreciation, with respect to available-for-sale fixed maturities are reported as a component of accumulated other comprehensive income, net of applicable

deferred income taxes, in stockholders' equity. Changes in unrealized appreciation and depreciation, with respect to trading securities, are reported as a component of income.

Investments in equity securities, which includes common stocks, are recorded at fair value with changes in value recorded as a component of income.

Other long-term investments consist primarily of our interests in limited liability partnerships that are recorded on the equity method of accounting.

Cash and Cash Equivalents

Cash and Cash Equivalents

For purposes of reporting cash flows, cash and cash equivalents include cash, money market accounts and non-negotiable certificates of deposit with original maturities of three months or less.

Deferred Policy Acquisition Costs ("DAC")

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.Our property and casualty insurance DAC is 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. This calculation is performed by line of business in a manner consistent with how the policies are currently being marketed and managed.

Property, Equipment and Depreciation

Property and equipment is presented at cost less accumulated depreciation.

Expenditures for maintenance and repairs on property and equipment are generally expensed as incurred. We periodically review these assets for impairment whenever events or changes in business circumstances indicate that the carrying value of the underlying asset may not be recoverable. A loss would be recognized if the estimated fair value of the asset were less than its carrying value.

Depreciation is computed primarily by the straight-line method over the following estimated useful lives:

	Useful Life
Computer equipment and software	Three years
Furniture and fixtures	Seven years
Internally developed software	Ten years
Leasehold improvements	Shorter of the lease term or useful life of the asset
Real estate	Seven years to thirty-nine years

Goodwill and Other Intangible Assets

Goodwill assets arise as a result of business combinations and consist of the excess of the fair value of consideration paid over the tangible and intangible assets acquired and liabilities assumed. The goodwill has been impaired to $0 for 2023, 2022 and 2021.

Our other intangible assets, which consist primarily of agency relationships, trade names, state insurance licenses, and software, are being amortized by 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

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.

The Company performs a quarterly review of its tax positions and makes a determination 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 position will be sustained, the Company will calculate any unrecognized tax benefits and calculate any interest and penalties. At December 31, 2023, 2022, and 2021 the Company did not recognize any liability for unrecognized tax benefits. 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.

Deferred tax assets are reduced by a valuation allowance when management believes it is more likely than not that some, or all, of the deferred taxes will not be realized. After considering all positive and negative evidence of taxable income in the carryback and carryforward periods and our tax planning strategy of holding debt securities with unrealized losses to recovery, we believe it is more likely than not that all the deferred assets will be realized. As a result, we have no valuation allowance at December 31, 2023 and 2022.

In 2023, 2022, and 2021, we made cash payments for income taxes of $1,348, $21,548 and $5,360, respectively. In 2023, 2022 and 2021 we received federal tax refunds of $14,017, $20,789 and $28,083, respectively, which resulted from the utilization of our net operating losses and net capital loss carryforwards and carrybacks. We have $185 of tax credit carryforwards expiring in 2039 through 2042. We made no interest payments in 2023, 2022 and 2021.

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 2018.

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 in 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 beneficiaries 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.

Stock-Based Compensation

We currently have two equity compensation plans. One plan allows us to grant restricted and unrestricted stock, stock appreciation rights, incentive stock options, and non-qualified stock options to employees. The other plan allows us to grant restricted and non-qualified stock options to non-employee directors.

We utilize the Black-Scholes option pricing method to establish the fair value of non-qualified stock options granted under our equity compensation plans. Our determination of the fair value of stock options on the date of grant using this option-pricing model is affected by our stock price, as well as assumptions regarding a number of complex and subjective variables, which include the expected volatility in our stock price, the expected term of the award, the expected dividends to be paid over the term of the award and the expected risk-free interest rate. Any changes in these assumptions may materially affect the estimated fair value of the award. For our restricted and unrestricted stock awards, we utilize the fair value of our common stock on the date of grant to establish the fair value of the award.

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 recognized 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 versus 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 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 for which the Company may be held accountable. 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 December 31, 2023 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 December 31, 2023, the Company had a credit loss allowance for reinsurance receivables of $97.

Rollforward of Credit Loss Allowance for Reinsurance Receivable
	As of
	December 31, 2023
Beginning balance, January 1, 2023	$	82
Current-period provision for expected credit losses	15
Ending balance of the allowance for reinsurance receivable, December 31, 2023	$	97

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. Outstanding audit premiums that are overdue after six months with no payments are written off and turned over to our collection agency.

Comprehensive Income

Comprehensive income includes all changes in stockholders' equity during a period except those resulting from investments by and dividends to stockholders.

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 modified disclosures but did not have an impact on the Company's financial position and results of operations.

Income Taxes

In December 2019 the FASB issued new guidance which simplifies the accounting for income taxes by removing certain exceptions to income tax accounting. The amendments also improve consistent application of and simplify GAAP for other areas of income tax accounting. The new guidance clarifies and amends existing guidance, including removing certain requirements that an entity evaluate when a step-up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction, and requiring an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. 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 did not have an impact on the Company's financial position and results of operations.

Accounting Standards Adopted in 2022

Inflation Reduction Act

On August 16, 2022, the U.S. government enacted the Inflation Reduction Act ("IRA") which, among other changes, created a new corporate alternative minimum tax ("CAMT") based on adjusted financial statement income and imposes a 1% excise tax on corporate stock repurchases. The effective date of these provisions is January 1, 2023. The Company was not subject to CAMT in 2023, does not expect to be subject to CAMT in 2024 and does not expect the IRA to have an impact on the Company's financial position and results of operations.

Fair Value Measurement

Current accounting guidance on fair value measurements includes the application of a fair value hierarchy that requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Our financial instruments that are recorded at fair value are categorized into a three-level hierarchy, which is based upon the priority of the inputs to the valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets (i.e., Level 1) and the lowest priority to unobservable inputs (i.e., Level 3). If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the financial instrument.

Financial instruments recorded at fair value are categorized in the fair value hierarchy as follows:

•Level 1: Valuations are based on unadjusted quoted prices in active markets for identical financial instruments that we have the ability to access.

•Level 2: Valuations are based on quoted prices for similar financial instruments, other than quoted prices included in Level 1, in markets that are not active or on inputs that are observable either directly or indirectly for the full term of the financial instrument.

•Level 3: Valuations are based on pricing or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement of the financial instrument. Such inputs may reflect management's own assumptions about the assumptions a market participant would use in pricing the financial instrument.

We review our fair value hierarchy categorizations on a quarterly basis at which time the classification of certain financial instruments may change if the input observations have changed. Transfers between levels, if any, are recorded as of the beginning of the reporting period.

To determine the fair value of the majority of our investments, we utilize prices obtained from independent, nationally recognized pricing services. We obtain one price for each security. When the pricing services cannot provide a determination of fair value for a specific security, we obtain non-binding price quotes from broker-dealers with whom we have had several years of experience and who have demonstrated knowledge of the subject security. We request and utilize one broker quote per security.

In order to determine the proper classification in the fair value hierarchy for each security where the price is obtained from an independent pricing service, we obtain and evaluate the vendors' pricing procedures and inputs used to price the security, which include unadjusted quoted market prices for identical securities, such as a New York Stock Exchange closing price, and quoted prices for identical securities in markets that are not active. For fixed maturity securities, an evaluation of interest rates and yield curves observable at commonly quoted intervals, volatility, prepayment speeds, credit risks and default rates may also be performed. We have determined that these processes and inputs result in fair values and classifications consistent with the applicable accounting guidance on fair value measurements.

When possible, we use quoted market prices to determine the fair value of fixed maturities, equity securities, trading securities and short-term investments. When quoted market prices do not exist, we base estimates of fair value on market information obtained from independent pricing services and brokers or on valuation techniques that are both unobservable and significant to the overall fair value measurement of the financial instrument. Such inputs may reflect management's own assumptions about the assumptions a market participant would use in pricing the financial instrument. Our valuation techniques are discussed in more detail throughout this section.

The 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 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 December 31, 2023, the cash surrender value of the COLI policies was $11,913, 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.

Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding during the reporting period. Diluted earnings per share gives effect to all dilutive common shares outstanding during the reporting period. The dilutive shares we consider in our diluted earnings per share calculation relate to our outstanding stock options 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. 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.
