United Fire Group, Inc. ("UFG", "United Fire", 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 a property and casualty insurer in 46 states, plus the District of Columbia.

We have historically reported our operations in two business segments: property and casualty insurance and life insurance. On September 18, 2017, the Company signed a definitive agreement to sell its subsidiary, United Life Insurance Company ("United Life"), to Kuvare US Holdings, Inc. ("Kuvare") and on March 30, 2018, the sale closed. As a result, our life insurance business, previously a separate segment, was considered held for sale and reported as discontinued operations in the Consolidated Balance Sheets, Consolidated Statements of Income and Comprehensive Income and Consolidated Statements of Cash Flows (collectively, the "Consolidated Financial Statements"). Subsequent to the announcement of this sale, our continuing operations are reported as one business segment. All current and prior periods reflected in this Form 10-K have been presented as continuing and discontinued operations, unless otherwise noted. For more information, refer to Note 17 "Discontinued Operations."

The accompanying Consolidated Financial Statements include United Fire and its wholly owned subsidiaries: United Fire & Casualty Company, United Real Estate Holdings Company, 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, and Mercer Insurance Company of New Jersey, Inc.

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.

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 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").

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The financial statement categories that are most dependent on management estimates and assumptions include: investments; deferred policy acquisition costs; reinsurance receivables and recoverables; future policy benefits and losses, claims and loss settlement expenses; and pension and post-retirement benefit obligations.

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 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.

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.

Our whole life and term insurance (i.e., traditional business) premiums are reported as earned when due and benefits and expenses are associated with premium income in order to result in the recognition of profits over the lives of the related contracts. Premiums receivable are presented net of an estimated allowance for doubtful accounts. Income annuities with life contingencies (single premium immediate annuities and supplementary contracts) have premium recorded and any related expense charge fees recorded as income and expense when the contract is issued. On universal life and deferred annuity policies (i.e., non-traditional business), income and expenses are reported when charged and credited to policyholder account balances in order to result in recognition of profits over the lives of the related contracts. We accomplish this by means of a provision for future policy benefits and the deferral and subsequent amortization of policy acquisition costs.

Liabilities for future policy benefits for traditional products are computed by the net level premium method, using interest assumptions ranging from 3.15 percent to 6.0 percent and withdrawal, mortality and morbidity assumptions appropriate at the time the policies were issued. Liabilities for non-traditional business are stated at policyholder account values before surrender charges. Liabilities for traditional immediate annuities are based primarily upon

Premiums earned and losses and loss settlement expenses incurred 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. Refer to Note 4 "Reinsurance" for a discussion of our reinsurance activities.

Investments in fixed maturities include bonds and redeemable preferred stocks. Our investments in held-to-maturity fixed maturities are recorded at amortized cost. Our investments in available-for-sale fixed maturities and trading securities are recorded at fair value.

In 2018, due to the change in accounting principle adopted on January 1, 2018 described in this section under "Recently Issued Accounting Standards," investments in equity securities, which include common and non-redeemable preferred stocks are recorded at fair value with changes in value recorded as a component of income. Prior to 2018, the change in the fair value of equity securities were held as available-for-sale securities and were 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 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.

Other long-term investments consist primarily of our interests in limited liability partnerships that are recorded on the equity method of accounting. Included in investments at December 31, 2018 and 2017, are securities on deposit with, or available to, various regulatory authorities as required by law, with fair values of $20,456 and $1,492,928 respectively.

In 2018, 2017, and 2016, we made cash payments for income taxes of $29,071, $7,667 and $24,034, respectively. In addition, we received federal tax refunds of $1,503 and $13,383 in 2018 and 2017, respectively, that resulted from the utilization of our 2011 net operating losses and net capital losses in the carryforward period. In 2016, we did not receive any federal tax refunds. We made no interest payments in 2018, 2017 and 2016. These payments exclude interest credited to policyholders' accounts.

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 that are reported in the accompanying Consolidated Financial Statements.

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

For the discontinued operations traditional life insurance policies, DAC is amortized to income over the premium-paying period in proportion to the ratio of the expected annual premium revenue to the expected total premium revenue. Expected premium revenue and gross profits are based on the same mortality and withdrawal assumptions used in determining future policy benefits. These assumptions are not revised after policy issuance unless the recorded DAC asset is deemed to be unrecoverable from future expected profits.

For the discontinued operations non-traditional life insurance policies, DAC is amortized over the anticipated terms in proportion to the ratio of the expected annual gross profits to the total expected gross profits. Changes in the amount or timing of expected gross profits result in adjustments to the cumulative amortization of these costs. The effect on amortization of DAC for revisions to estimated gross profits is reported in earnings in the period the estimated gross profits are revised.

The effect on DAC that results from the assumed realization of unrealized gains (losses) on investments allocated to non-traditional life insurance business is recognized with an offset to net unrealized investment appreciation as of the balance sheet date. The impact of unrealized gains (losses) on available-for-sale securities decreased the DAC asset by $6,294 and $6,413 at December 31, 2017 and 2016, respectively. There was no impact of unrealized gains and losses on available-for-sale securities on the DAC asset at December 31, 2018 because the non-traditional life insurance business is part of discontinued operations, which was sold on March 30, 2018.

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.

Goodwill and other intangible assets arise as a result of business combinations and consist of the excess of the fair value of consideration paid over the tangible assets acquired and liabilities assumed. All of our goodwill and the majority of our intangible assets relate to the acquisition of Mercer Insurance Group on March 28, 2011. We evaluate goodwill and other intangible assets for impairment at least on an annual basis or whenever events or changes in circumstances indicate that it is more likely than not that the carrying amount of goodwill and other intangible assets may exceed its implied fair value. Goodwill is evaluated at the reporting unit level. Any impairment is charged to operations in the period that the impairment is identified. In 2016 we performed a quantitative impairment assessment of our goodwill and in 2018 and 2017, we performed a qualitative impairment assessment of our goodwill. As a result of these assessments, we did not recognize an impairment charge on our goodwill in 2018, 2017 or 2016.

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 2 years to 15 years, with the exception of state insurance licenses, which are indefinite-lived and not amortized. In 2016 we performed a quantitative impairment assessment of our indefinite-lived intangible assets and, in 2018 and 2017, we performed a qualitative impairment assessment of our indefinite lived intangible assets. As a result of these assessments, we did not recognize an impairment charge on our intangible assets in 2018, 2017 and 2016. Amortization expense totaled $719 in 2018, 2017 and 2016, respectively.

The Tax Cuts and Jobs Act of 2017 (the "Tax Act") was enacted on December 22, 2017. The Tax Act significantly revised the U.S. corporate income tax laws including lowering the U.S. federal corporate tax rate from 35 percent to 21 percent, effective January 1, 2018.

In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed in reasonable detail to complete its accounting for the effect of the changes in the Tax Act. The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year. As of December 31, 2018 we have completed accounting for the tax effects of enactment of the Tax Act and no adjustments were made during the measurement period.

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, 2018, 2017, and 2016 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.

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. Refer to Note 9 "Stock-Based Compensation" for further discussion.

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.

In May 2014, the FASB issued comprehensive new guidance on revenue recognition which supersedes nearly all existing revenue recognition guidance under GAAP. The new guidance requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard creates a five-step model that requires companies to exercise judgment when considering the terms of the contract(s) and all relevant facts and circumstances. Insurance contracts are not within the scope of this new guidance. The new guidance is effective for annual and interim periods beginning after December 15, 2017. The Company adopted the guidance as of January 1, 2018. The adoption of the new guidance had no impact on the Company's reporting and disclosure of net premiums earned from insurance contracts, net investment income or net realized gains and losses, as these revenue streams are not within the scope of this new guidance. The remaining revenue streams are immaterial and not impacted by the new standard.

In January 2016, the FASB issued guidance updating certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments in this update supersede the guidance to classify equity securities with readily determinable fair values into different categories (for example, trading or available-for-sale) and require equity securities to be measured at fair value with changes in the fair value recognized through net income. The new guidance also simplifies the impairment process for equity investments without readily determinable fair values. The new guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those years. The Company adopted the new guidance as of January 1, 2018. The adoption of the new guidance resulted in a reclassification from accumulated other comprehensive income to retained earnings of $191,244 after tax, which is equal to the amount of net unrealized gains and losses on available-for-sale equity securities on January 1, 2018. Also, in the period ended December 31, 2018, the Company recognized an after-tax net realized investment loss from continuing operations of $17,375 in net income from the change in value of equity securities in accordance with the adoption of this new accounting guidance.

In August 2016, the FASB issued an update that clarifies the classification of certain cash receipts and payments in the Statement of Cash Flows. The update addresses eight existing cash flow issues by clarifying the correct classification to establish uniformity in practice. The updated guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those years. The Company adopted the new guidance as of January 1, 2018. The adoption had no impact on the Company's financial position and results of operations.

In March 2017, the FASB issued guidance on the presentation of net periodic benefit costs of defined benefit retirement benefit plans in the Statements of Income. The new guidance requires the service cost component of net periodic benefit cost of defined benefit plans to be presented in the same line in the Statements of Income as other employee compensation expenses. Also, under the new guidance, the service cost component of the net periodic benefit costs will be the only portion of costs subject to be capitalized in assets. The new guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those years. The Company adopted the new guidance as of January 1, 2018. The adoption of the new guidance resulted in a change in the capitalization of deferred acquisition costs to only include the pension and post retirement service costs in place of the total net periodic benefit costs. The adoption had an immaterial impact on the Company's financial position and results of operations. Additionally, the adoption did not impact the Company's presentation in the Statements of Income as all net periodic benefit costs and employee compensation expenses are included within the same category in the Statements of Income.

In May 2017, the FASB issued new guidance which clarifies and addresses the diversity in practice when there is a change in the terms of a share-based payment award. The updated guidance clarifies when to use modification accounting when there is a change in the terms of a share-based payment and provides three conditions where modification accounting should not be applied. The new guidance is effective for annual and interim periods beginning after December 15, 2017. The Company adopted the new guidance as of January 1, 2018. The adoption had no impact on the Company's financial position and results of operations.

In August 2018, the FASB issued guidance to align the requirements for capitalizing implementation costs incurred in a cloud computing hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The guidance requires the Company to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The new guidance is effective for annual and interim periods beginning after December 15, 2019. The Company will adopt the new guidance as of January 1, 2020. Management currently believes that the adoption will not have an impact on the Company's financial position or results of operations.

In February 2016, the FASB issued guidance on the accounting for leases. The new guidance requires lessees to place a right-of-use asset and a lease liability on their balance sheets. The lease liability will be based on the present value of the future lease payments and the right-of-use asset will be based on the liability. Expenses will be recognized on the income statement in a similar manner as previous methods. The new guidance also requires companies to classify all leases as operating leases or financing leases. We believe all of our leases will be classified as operating leases. The new guidance is effective for annual periods beginning after December 15, 2018 and interim periods within those years. The Company will adopt the new guidance under a modified retrospective transition approach using the package of practical expedients and the Company will not adopt the hindsight practical expedient as of January 1, 2019. We expect to use the accounting standard adoption date as our date of initial application.

The Company has an inventory of its operating leases and has calculated the total undiscounted future minimum lease payments, which are disclosed in Note 13 "Lease Commitments" of this report. The Company estimates the present value of future minimum lease payments at December 31, 2018 is $20.1 million, which represents less than 1.0 percent of the Company's total assets at December 31, 2018. The Company will record this amount as a lease liability on their Balance Sheets on January 1, 2019 and an estimated right-of-use asset of $19.7 million. The Company used their incremental borrowing rate of their credit facility described in Note 14 "Credit Facility" of this Form 10-K, as the discount rate for calculating the present value of the future minimum lease payments where appropriate. For leases that existed prior to the date of initial application or have terms which are not similar to the terms of the credit facility, the Company has elected to use the remaining lease term as of the date of initial application to measure its incremental borrowing rate. In this case, the incremental borrowing rate will be based on current industry borrowing rates for similar Companies with similar ratings.

The Company has a small inventory of property leases for which the Company is the lessor. For these leases, the Company has made the election not to evaluate whether certain sales taxes are the primary obligation of the lessor as owner of the leased asset. The Company has reviewed and updated its processes and controls under the new guidance. Management currently believes that the adoption will not have a significant impact on the Company's financial position or results of operations.

doesn’t change the accounting for securities held at a discount, which will continue to be amortized to maturity. The new guidance is effective for annual periods beginning after December 15, 2018 and interim periods beginning after December 15, 2018. The Company will adopt the new guidance as of January 1, 2019. The adoption will have not have a material impact on the Company's financial position and results of operations.

In October 2016, the FASB issued new guidance on the income tax treatment of intra-entity transfers. The new guidance replaces the current guidance which prohibits the recognition of current and deferred income taxes of intra-entity transfers until the asset is sold externally. Under the new guidance, the exemption is eliminated and income taxes will be recognized on transfers of intra-entity assets. The new guidance is effective for annual periods beginning after December 15, 2018 and interim periods beginning after December 15, 2019. The Company will adopt the new guidance as of January 1, 2019. Management currently believes that the adoption will have an immaterial impact on the Company's financial position and results of operations.

In June 2016, the FASB issued new guidance on the measurement of credit losses for most financial instruments. The new guidance replaces the current incurred loss model for recognizing credit losses with an expected loss model for instruments measured at amortized cost and requires allowances to be recorded for available-for-sale debt securities rather than reduce the carrying amount. These allowances will be remeasured each reporting period. The new guidance is effective for annual periods beginning after December 15, 2019 and interim periods within those years. The new guidance will impact the Company's portfolio of mortgage loan investments which are carried at amortized cost and the impairment model related to our available-for-sale fixed-maturity portfolio. The Company will adopt the new guidance as of January 1, 2020 and is currently evaluating the impact on the Company's financial position, results of operations and key processes.

In January 2017, the FASB issued new guidance which simplifies the test for goodwill impairment. The new guidance eliminates the implied fair value calculation when measuring a goodwill impairment charge. Under the new guidance, impairment charges will be based on the excess of the carrying value over fair value of goodwill. The new guidance is effective for annual and interim periods beginning after December 15, 2019. The Company will adopt the new guidance as of January 1, 2020 and it currently believes the adoption will have no impact on the Company's financial position and results of operations.

In August 2018, the FASB issued new guidance which modifies the disclosure requirements on fair value measurements of financial instruments. The new guidance removes the requirement for disclosing the amount and reason for transfers between Level 1 and Level 2 investment securities and the valuation processes for Level 3 fair value measurements. The guidance also requires additional disclosures on the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The new guidance is effective for annual and interim periods beginning after December 15, 2019. The Company will adopt the new guidance as of January 1, 2020. Management currently believes the new guidance will modify existing fair value disclosures, but will not have an impact on the Company's financial position and results of operations.

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, 2019. The Company will adopt the new guidance as of January 1, 2020. Management currently believes the new guidance will
