Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Accounting and Consolidation	Note 1 – Basis of Accounting and Consolidation The accompanying consolidated financial statements include the accounts of First Mid Bancshares, Inc. (“Company”) and its wholly-owned subsidiaries: First Mid Bank & Trust, N.A. (“First Mid Bank”), Mid-Illinois Data Services, Inc. (“MIDS”), First Mid Wealth Management Company, First Mid Insurance Group, Inc. (“First Mid Insurance”) and First Mid Captive, Inc. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts in the prior year’s consolidated financial statements have been reclassified to conform to the 2020 presentation and there was no impact on net income or stockholders’ equity from these reclassifications. The Company operates as a single segment entity for financial reporting purposes. The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America. COVID-19 The COVID-19 outbreak is an unprecedented event that provides significant economic uncertainty for a broad spectrum of industries. The Company is focused on supporting its customers, communities and employees during this unique operating environment. Throughout this document, the Company describes the impact COVID-19 is having, actions taken as a result of COVID-19, and certain risks to the Company that COVID-19 creates or exacerbates, as well as management's outlook on the current COVID-19 situation. Acquisition On September 25, 2020, the Company and Eval Sub Inc., wholly-owned subsidiary of the Company ("Merger Sub"), entered into an Agreement and Plan of Merger (the "Merger Agreement") with LINCO Bancshares, Inc., the former parent of Providence Bank ("LINCO"), and the sellers as defined therein, pursuant to which, among other things, the Company agreed to acquire 100% of the issued and outstanding shares of LINCO pursuant to a business combination whereby Merger Sub merged with and into LINCO, whereupon the separate corporate existence of Merger Sub ceased and LINCO continued as the surviving company and a wholly-owned subsidiary of the Company (the "Merger"). Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each share of common stock, par value $1.00 per share, of LINCO issued and outstanding immediately prior to the effective time of the Merger (other than shares held in treasury by LINCO) was converted into and become the right to receive, cash or shares of common stock, par value $4.00 per share, of the Company and cash in lieu of fractional shares, less any applicable taxes required to be withheld, and subject to certain potential adjustments. On an aggregate basis, the total consideration payable by the Company at the closing of the Merger was $103.5 million in cash and 1,262,246 shares of the Company’s common stock, provided that the shareholders of LINCO collectively elected pursuant to the Merger Agreement to receive varying amounts of cash or shares of common stock of the Company as consideration in the Merger. In addition, immediately prior to the closing of the proposed merger, LINCO paid a special dividend to its shareholders in the aggregate amount of $13 million. The Merger closed on February 22, 2021. It is anticipated that Providence Bank will be merged with and into First Mid Bank in the second quarter of 2021. At the time of the bank merger, Providence Bank’s banking offices will become branches of First Mid Bank. Website The Company maintains a website at www.firstmid.com General Litigation The Company is subject to claims and lawsuits that arise primarily in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits will not have a material adverse effect on the consolidated financial position, results of operations and cash flows of the Company. Loan Purchase On April 21, 2020, First Mid Bank completed an acquisition of loans in the St. Louis metro market totaling $183 million. There were no loans purchased with deteriorated credit. Summary of Significant Accounting Policies Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company uses estimates and employs the judgments of management in determining the amount of its allowance for credit losses and income tax accruals and deferrals, in its fair value measurements of investment securities, and in the evaluation of impairment of loans, goodwill, investment securities, and premises and equipment. As with any estimate, actual results could differ from these estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses. In connection with the determination of the allowance for credit losses, management obtains independent appraisals for significant properties. Fair Value Measurements The fair value of a financial instrument is defined as the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The Company estimates the fair value of a financial instrument using a variety of valuation methods. Where financial instruments are actively traded and have quoted market prices, quoted market prices are used for fair value. When the financial instruments are not actively traded, other observable market inputs, such as quoted prices of securities with similar characteristics, may be used, if available, to determine fair value. When observable market prices do not exist, the Company estimates fair value. The Company’s valuation methods consider factors such as liquidity and concentration concerns. Other factors such as model assumptions, market dislocations, and unexpected correlations can affect estimates of fair value. Imprecision in estimating these factors can impact the amount of revenue or loss recorded. At the end of each quarter, the Company assesses the valuation hierarchy for each asset or liability measured. From time to time, assets or liabilities may be transferred within hierarchy levels due to changes in availability of observable market inputs to measure fair value at the measurement date. Transfers into or out of hierarchy levels are based upon the fair value at the beginning of the reporting period. A more detailed description of the fair values measured at each level of the fair value hierarchy can be found in Note 11 – “Disclosures of Fair Values of Financial Instruments.” Cash and Cash Equivalents For purposes of reporting cash flows, cash equivalents include non-interest bearing and interest-bearing cash and due from banks and federal funds sold. Generally, federal funds are sold for one-day Certificates of Deposit Investments Certificates of deposit investments have original maturities of three to five years and are carried at cost. Investment Securities The Company classifies its investments in debt securities as either held-to-maturity or available-for-sale in accordance with ASC 320. Securities classified as held-to-maturity are recorded at cost or amortized cost. Available-for-sale securities are carried at fair value. Fair value calculations are based on quoted market prices when such prices are available. If quoted market prices are not available, estimates of fair value are computed using a variety of techniques, including extrapolation from the quoted prices of similar instruments or recent trades for thinly traded securities, fundamental analysis, or through obtaining purchase quotes. Due to the subjective nature of the valuation process, it is possible that the actual fair values of these investments could differ from the estimated Loans Loans are stated at the principal amount outstanding net of unearned discounts, unearned income and the allowance for credit losses. Unearned income includes deferred loan origination fees reduced by loan origination costs and is amortized to interest income over the life of the related loan using methods that approximate the effective interest rate method. Interest on substantially all loans is credited to income based on the principal amount outstanding. The Company’s policy is to discontinue the accrual of interest income on any loan that becomes ninety days past due as to principal or interest or earlier when, in the opinion of management there is reasonable doubt as to the timely collection of principal or interest. Nonaccrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collectability of interest or principal. Loans expected to be sold are classified as held for sale in the consolidated financial statements and are recorded at the lower of aggregate cost or fair value, taking into consideration future commitments to sell the loans. Allowance for Credit Losses The Company believes the allowance for credit losses is the critical accounting policy that requires the most significant judgments and assumptions used in the The Company estimates the appropriate level of allowance for credit losses by separately evaluating impaired and nonimpaired loans. A specific allowance is assigned to an impaired loan when expected cash flows or collateral do not justify the carrying amount of the loan. The methodology used to assign an allowance to a nonimpaired loan is more subjective. Generally, the allowance assigned to nonimpaired loans is determined by applying historical loss rates to existing loans with similar risk characteristics, adjusted for qualitative factors including the volume and severity of identified classified loans, changes in economic conditions, changes in credit policies or underwriting standards, and changes in the level of credit risk associated with specific industries and markets. Because the economic and business climate in any given industry or market, and its impact on any given borrower, can change rapidly, the risk profile of the loan portfolio is continually assessed and adjusted when appropriate. Notwithstanding these procedures, there still exists the possibility that the assessment could prove to be significantly incorrect and that an immediate adjustment to the allowance for credit losses would be required. Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is charged to expense and determined principally by the straight-line method over the estimated useful lives of the assets. The estimated useful lives for each major depreciable classification of premises and equipment are as follows: Buildings 20 years to 40 years Leasehold 5 years to 15 years Furniture 3 years to 7 years Goodwill and Intangible Assets The Company has goodwill from business combinations, identifiable intangible assets assigned to core deposit relationships and customer lists acquired, and intangible assets arising from the rights to service mortgage loans for others. Identifiable intangible assets generally arise from branches acquired that the Company accounted for as purchases. Such assets consist of the excess of the In accordance with the provisions of SFAS No. 142, “ Goodwill and Other Intangible Assets Other Real Estate Owned Other real estate owned acquired through loan foreclosure is initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. The adjustment at the time of foreclosure is recorded through the allowance for credit losses. Due to the subjective nature of establishing the fair value when the asset is acquired, the actual fair value of the other real estate owned or foreclosed asset could differ from the original estimate. If it is determined that fair value temporarily declines subsequent to foreclosure, a valuation allowance is recorded through noninterest expense. Operating costs associated with the assets after acquisition are also recorded as noninterest expense. Gains and losses on the disposition of other real estate owned and foreclosed assets are netted and posted to other noninterest expense. Bank Owned Life Insurance First Mid Bank has purchased life insurance policies on certain senior management. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts that are probable at settlement. Federal Home Loan Bank Stock Federal Home Loan Bank stock is a required investment for institutions that are members of the Federal Home Loan Bank system. The required investment in the common stock is based on a predetermined formula. Income Taxes The Deferred tax assets and liabilities are recognized for future tax consequences attributable to the temporary differences existing between the financial statement carrying amounts of assets and liabilities and their respective tax basis, as well as operating loss and tax credit carry forwards. To the extent that current available evidence about the future raises doubt about the realization of a deferred tax asset, a valuation allowance is established. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as an increase or decrease in income tax expense in the period in which such change is enacted. Additionally, the Company reviews its uncertain tax positions annually under FASB Interpretation No. 48 (FIN No. 48), “ Accounting for Uncertainty in Income Taxes ,” Captive Insurance Company First Mid Captive, Inc. ("the Captive"), a wholly-owned subsidiary of the Company which was formed and began operations in December 2019, is a Nevada- based captive insurance company. The Captive insures against certain risks unique to the operations of the Company and its subsidiaries for which insurance may not be currently available or economically feasible in today's insurance marketplace. The Captive pools resources with several other similar insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. The Captive is subject to regulations of the State of Nevada and undergoes periodic examinations by the Nevada Division of Insurance. It has elected to be taxed under Section 831(b) of the Internal Revenue Code. Pursuant to Section 831(b), if gross premiums do not exceed $2,300,000, then the Captive is taxable solely on its investment income. The Captive is included in the Company's consolidated financial statements and its federal income return. Trust Assets Assets held in fiduciary or agency capacities by First Mid Wealth Management Company are not included in the consolidated balance sheets since such items are not assets of the Company or its subsidiaries. Fees from trust activities are recorded on a cash basis over the period in which the service is provided. Fees are a function of the market value of assets managed and administered, the volume of transactions, and fees for other services rendered, as set forth in the underlying client agreement with the First Mid Wealth Management Company. This revenue recognition involves the use of estimates and assumptions, including components that are calculated based on asset valuations and transaction volumes. Any out of pocket expenses or services not typically covered by the fee schedule for trust activities are charged directly to the trust account on a gross basis as trust revenue is incurred. At December 31, 2020, the First Mid Wealth Management Company managed or administered 1,411 trust accounts with assets totaling approximately $1,563.0 million. At December 31, 2019, the Company managed or administered 1,635 trust accounts with assets totaling approximately $1,487.5 million. Treasury Stock Treasury stock is stated at cost. Cost is determined by the first-in, first-out method. Stock Incentive Awards At ten-year A maximum of 149,983 shares of common stock may be issued under the SI Plan. The Company awarded 25,950, 26,700, and 28,700 shares during 2020, 2019, and 2018, respectively as stock and stock unit awards. Employee Stock Purchase Plan At ESPP. 2020 and the ESPP. Leases Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic ATM Revenue Recognition Accounting Revenue from Contracts with Customers Trust revenues. The Company generates fee income from providing fiduciary services through its trust department. Fees are billed in arrears based upon the preceding period account balance. Revenue from the farm management department is recorded when service is complete, for example when crops are sold. Brokerage commissions. The primary brokerage revenue is recorded at the beginning of each quarter through billing to customers based on the account asset size on the last day of the previous quarter. If a withdrawal of funds takes place, a prorated refund may occur; this is reflected within the same quarter as the original billing occurred. All performance obligations are met within the same quarter that the revenue is recorded. Insurance commissions. The Company’s insurance agency subsidiary, First Mid Insurance, receives commissions on premiums of new and renewed business policies. First Mid Insurance records commission revenue on direct bill policies as the cash is received. For agency bill policies, First Mid Insurance retains its commission portion of the customer premium payment and remits the balance to the carrier. In both cases, the entire performance obligation is held by the carriers. Service charges on deposits. The Company generates revenue from fees charged for deposit account maintenance, overdrafts, wire transfers, and check fees. The revenue related to deposit fees is recognized at the time the performance obligation is satisfied. ATM/debit card revenue. The Company generates revenue through service charges on the use of its ATM machines and interchange income from the use of Company issued credit and debit cards. The revenue is recognized at the time the service is used and the performance obligation is satisfied. Other income. Treasury management fees and lock box fees are received and recorded after the service performance obligation is completed. Merchant bank card fees are received from various vendors, however the performance obligation is with the vendors. The Company records gains on the sale of loans and the sale of OREO properties after the transactions are complete and transfer of ownership has occurred. As each of the Company’s facilities is located in markets with similar economies, no disaggregation of revenue is necessary. Adoption of New Accounting Guidance Accounting Standards Update 2017-04, Intangibles-Goodwill and Other (Topic 350: Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). In January 2017, FASB issued ASU 2017-04. The amendments in this update simplify the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under this guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for public companies for the reporting periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Although the Company cannot anticipate future goodwill impairment, based on the most recent assessment, it is unlikely that an impairment amount would need to be calculated and, therefore, does not anticipate a material impact on the Company's financial statements. The current accounting policies and procedures of the Company did not change, except for the elimination of Step 2 analysis. Accounting Standards Update 2016-02, Leases (Topic 842)("ASU 2016-02"). On February 25, 2016, FASB issued ASU 2016-02 which creates Topic 842, Leases and supersedes Topic 840, Leases. ASU 2016-02 is intended to improve financial reporting about leasing transactions, by increasing transparency and comparability among organizations. Under the new guidance, a lessee is required to record all leases with lease terms of more than 12 months on their balance sheet as lease liabilities with a corresponding right-of-use asset. ASU 2016-02 maintains the dual model for lease accounting, requiring leases to be classified as either operating or finance, with lease classification determined in a manner similar to existing lease guidance. The new guidance is effective for public companies for fiscal years beginning on or after December 15, 2018, and for private companies for fiscal years beginning on or after December 15, 2019. The Company adopted the guidance effective January 1, 2019 and recorded a right of use asset of $14.1 million and a lease liability of $14.1 million. Accounting Standards Update 2018-13, Fair Value Measurements (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). In August 2018, FASB issued ASU 2018-13. This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, an entity will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019. As ASU 2018-13 only revises disclosure requirements, it did not have a material impact on the Company’s consolidated financial statements. Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments (“ASU 2016-13”). In June 2016, FASB issued ASU 2016-13. The provisions of ASU 2016-13 requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime "expected credit loss" and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. ASU 2016-13 also requires new disclosures for financial assets measured at amortized cost, loans and available-for- sale debt securities. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Management formed an internal, cross functional committee in 2017 to evaluate implementation steps and assess the impact ASU 2016-13 would have on the Company’s consolidated financial statements. The committee assigned roles and responsibilities, key tasks to complete, and established a general time-line for implementation. The Company also engaged an The Company adopted ASU 2016-13 using the modified retrospective method for financial assets measured at amortized cost-effective January 1, 2020. Results for the periods beginning after January 1, 2020 are presented under ASU 2016-13 while prior period amounts are reported in accordance with the previously applicable accounting standards. The Company recorded a reduction to retained earnings of approximately $717,000 upon adoption of ASU 2016-13. The transition adjustment included an increase to the allowance for credit losses on loans of $1.7 million and an increase to the allowance for credit losses on off-balance sheet credit exposure of $69,000. There was no allowance for credit losses recorded for held-to- maturity debt securities. The transition adjustment included corresponding increases in deferred tax assets. The Company adopted ASU 2016-13 using the prospective transition approach for financial assets considered purchased credit deteriorated ("PCD") that were previously classified as purchase credit impaired ("PCI") and accounted for under ASC 310-30 effective January 1, 2020. In accordance with the standard, the Company did not reassess whether the PCI assets met the criteria of PCD assets as of the adoption date. The amortized cost of the PCD assets were adjusted to reflect the addition of $833,000 to the allowance for credit losses. The remaining noncredit discount (based on the adjusted amortized cost) will be accreted into interest income at the effective interest rate over the remaining life of the assets.

The entire balance of a loan is considered delinquent if the minimum payment contractually required to be made is not received by the specified due date. Impaired loans, excluding certain troubled debt restructured loans, are placed on nonaccrual status. Impaired loans include nonaccrual loans and loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. It is the Company’s policy to have any restructured loans which are on nonaccrual status prior to being modified remain on nonaccrual status until, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collection of interest or principal. If the restructured loan is on accrual status prior to being modified, the loan is reviewed to determine if the modified loan should remain on accrual status.

The accrual of interest is discontinued earlier when, in the opinion of management, there is reasonable doubt as to the timely collection of interest or principal. Once interest accruals are discontinued, accrued but uncollected interest is charged against current year income. Subsequent receipts on non-accrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured. Interest on loans determined to be troubled debt restructurings is recognized on an accrual basis in accordance with the restructured terms if the loan is in compliance with the modified terms. Nonaccrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collection of interest or principal. The Company requires a period of satisfactory performance of not less than six months before returning a nonaccrual loan to accrual status. The following tables present average recorded investment and interest income recognized on impaired loans for the years ended December 31, 2020, 2019 and 2018 (in thousands): 2020 2019 2018 Average Investment in Impaired Loans Interest Income Recognized Average Investment in Impaired Loans Interest Income Recognized Average Investment in Impaired Loans Interest Income Recognized Construction and land development $ 694 $ 7 $ 622 $ 32 $ 2,558 $ 37 Farm loans 827 — 1,218 — 415 — 1-4 Family residential properties 8,557 17 9,659 80 6,297 144 Multifamily residential properties 2,325 — 6,490 89 9,666 137 Commercial real estate 12,387 41 12,189 234 9,818 271 Loans secured by real estate 24,790 65 30,178 435 28,754 589 Agricultural loans 815 — 808 3 727 23 Commercial and industrial loans 4,941 1 10,065 9 9,003 6 Consumer loans 392 — 649 1 131 1 All other loans — — — — 3 — Total loans $ 30,938 $ 66 $ 41,700 $ 448 $ 38,618 $ 619 The amount of interest income recognized by the Company within the periods stated above was due to loans modified in a troubled debt restructuring that remained on accrual status. The average balance of loans modified in a troubled debt restructuring included in the impaired loans stated above that were still accruing was $4.4 million, $2.7 million and $2.5 million for the years ended December 31, 2020, 2019 and 2018, respectively. The amount of interest income recognized using a cash-basis method of accounting during the period that the loans were impaired was not material. Nonaccr" id="sjs-B4">Note 5 -- Loans and Allowance for Credit Losses Loans are stated at the principal amount outstanding net of unearned discounts, unearned income and allowance for credit losses. Unearned income includes deferred loan origination fees reduced by loan origination costs and is amortized to interest income over the life of the related loan using methods that approximated the effective interest rate method. Interest on substantially all loans is credited to income based on the principal amount outstanding.

The structure of the Company’s loan approval process is based on progressively larger lending authorities granted to individual loan officers, loan committees, and ultimately the board of directors. Outstanding balances to one borrower or affiliated borrowers are limited by federal regulation; however, limits well below the regulatory thresholds are generally observed. The vast majority of the Company’s loans are to businesses located in the geographic market areas served by the Company’s branch bank system. Additionally, a significant portion of the collateral securing the loans in the portfolio is located within the Company’s primary geographic footprint. In general, the Company adheres to loan underwriting standards consistent with industry guidelines for all loan segments. The Company’s lending can be summarized into the following primary areas: Commercial Real Estate Loans. Commercial real estate loans are generally comprised of loans to small business entities to purchase or expand structures in which the business operations are housed, loans to owners of real estate who lease space to non-related commercial entities, loans for construction and land development, loans to hotel operators, and loans to owners of multi-family residential structures, such as apartment buildings. Commercial real estate loans are underwritten based on historical and projected cash flows of the borrower and secondarily on the underlying real estate pledged as collateral on the debt. For the various types of commercial real estate loans, minimum criteria have been established within the Company’s loan policy regarding debt service coverage while maximum limits on loan-to-value and amortization periods have been defined. Maximum loan- to-value ratios range from 65 % to 80 % depending upon the type of real estate collateral, while the desired minimum debt coverage ratio is 1.20x . Amortization periods for commercial real estate loans are generally limited to twenty years. The Company’s commercial real estate portfolio is well below the thresholds that would designate a concentration in commercial real estate lending, as established by the federal banking regulators. Commercial and Industrial Loans. Commercial and industrial loans are primarily comprised of working capital loans used to purchase inventory and fund accounts receivable that are secured by business assets other than real estate. These loans are generally written for one year or less. Also, equipment financing is provided to businesses with these loans generally limited to 80% of the value of the collateral and amortization periods limited to seven years. Commercial loans are often accompanied by a personal guaranty of the principal owners of a business. Like commercial real estate loans, the underlying cash flow of the business is the primary consideration in the underwriting process. The financial condition of commercial borrowers is monitored at least annually with the type of financial information required determined by the size of the relationship. Measures employed by the Company for businesses with higher risk profiles include the use of government-assisted lending programs through the Small Business Administration and U.S. Department of Agriculture Agricultural and Agricultural Real Estate Loans. Agricultural loans are generally comprised of seasonal operating lines to cash grain farmers to plant and harvest corn and soybeans and term loans to fund the purchase of equipment. Agricultural real estate loans are primarily comprised of loans for the purchase of farmland. Specific underwriting standards have been established for agricultural-related loans including the establishment of projections for each operating year based on industry developed estimates of farm input costs and expected commodity yields and prices. Operating lines are typically written for one year and secured by the crop. Loan-to-value ratios on loans secured by farmland generally do not exceed 65 and have amortization periods limited to twenty-five years. Federal government-assistance lending programs through the Farm Service Agency are used to mitigate the level of credit risk when deemed appropriate Residential Real Estate Loans. Residential real estate loans generally include loans for the purchase or refinance of residential real estate properties consisting of one-to-four units and home equity loans and lines of credit. The Company sells the vast majority of its long-term fixed rate residential real estate loans to secondary market investors. The Company also releases the servicing of these loans upon sale. The Company retains all residential real estate loans with balloon payment features. Balloon periods are limited to five years. Residential real estate loans are typically underwritten to conform to industry standards including criteria for maximum debt-to-income and loan-to-value ratios as well as minimum credit scores. Loans secured by first liens on residential real estate held in the portfolio typically do not exceed 80% of the value of the collateral and have amortization periods of twenty-five years or less. The Company does not originate subprime mortgage loans Consumer Loans. Consumer loans are primarily comprised of loans to individuals for personal and household purposes such as the purchase of an automobile or other living expenses. Minimum underwriting criteria have been established that consider credit score, debt-to-income ratio, employment history, and collateral coverage. Typically, consumer loans are set up on monthly payments with amortization periods based on the type and age of the collateral. Other Loans. Other loans consist primarily of loans to municipalities to support community projects such as infrastructure improvements or equipment purchases. Underwriting guidelines for these loans are consistent with those established for commercial loans with the additional repayment source of the taxing authority of the municipality. Allowance for Credit Losses The allowance for credit losses represents the Company’s best estimate of the reserve necessary to adequately account for probable losses expected over the remaining contractual life of the assets. The provision for credit losses is the charge against current earnings that is determined by the Company as the amount needed to maintain an adequate allowance for credit losses. In determining the adequacy of the allowance for credit losses, and therefore the provision to be charged to current earnings, the Company relies predominantly on a disciplined credit review and approval process that extends to the full range of the Company’s credit exposure. The review process is directed by the overall lending policy and is intended to identify, at the earliest possible stage, borrowers who might be facing financial difficulty. Factors considered by the Company in evaluating the overall adequacy of the allowance include historical net loan losses, the level and composition of nonaccrual, past due and troubled debt restructurings, trends in volumes and terms of loans, effects of changes in risk selection and underwriting standards or lending practices, lending staff changes, concentrations of credit, industry conditions and the current economic conditions in the region where the Company operates. The Company estimates the appropriate level of allowance for credit losses by evaluating large impaired loans separately from non-impaired loans. Impaired loans The Company individually evaluates certain loans for impairment. In general, these loans have been internally identified via the Company’s loan grading system as credits requiring management’s attention due to underlying problems in the borrower’s business or collateral concerns. This evaluation considers expected future cash flows, the value of collateral and also other factors that may impact the borrower’s ability to make payments when due. For loans greater than $250,000, and loans identified as troubled debt restructurings, impairment is individually measured each quarter using one of three alternatives: (1) the present value of expected future cash flows discounted at the loan’s Non-Impaired loans Non-impaired loans comprise the vast majority of the Company’s total loan portfolio and include loans in accrual status and those credits not identified as troubled debt restructurings. A small portion of these loans are considered “criticized” due to the risk rating assigned reflecting elevated credit risk due to characteristics, such as a strained cash flow position, associated with the individual borrowers. Criticized loans are those assigned risk ratings of Special Mention, Substandard, or Doubtful. Beginning January 1, 2020, the allowance for credit losses was estimated using the current expected credit loss model ("CECL"). The Company uses the Loss Rate method to estimate the historical loss rate for all non-impaired loans. Under this method, the allowance for credit losses is measured on a collective (pool) basis for non-impaired loans with similar risk characteristics. Historical credit loss experience provides the basis for the estimate of expected credit losses. For each pool, a historical loss rate is computed based on the average remaining contractual life of the pool. Adjustments to historical loss rates are made using qualitative factors relevant to each pool including merger & acquisition activity, economic conditions, changes in policies, procedures & underwriting, and concentrations. In addition, a twelve-month forecast, using reasonable and supportable future conditions, is prepared that is used to estimate expected changes to existing and historical conditions in the current period. The Within Construction and Land Development Loans. The average life of the construction and land development segment was determined to be twelve months. Historical losses in this segment remained very low. Current activity in this industry was deemed essential and has continued during COVID-19. There was no adjustment to t he qualitative factor for this segment. Agricultural Real Estate Loans. The average life of the agricultural real estate segment was determined to be thirty-six months. Historical losses in the segment remain very low. Farmland values have remained steady over an extended period of time and there are no indications that this will change in the next year. There was a slight adjustment down to the qualitative factor for this segment to reflect the improvement in the overall agriculture economy. 1- 4 Family Residential Properties Loans. The average life of the 1-4 Family Residential segment was determined to be: Residential Real Estate-non-owner occupied, sixty months; Residential Real Estate-owner occupied, sixty months; Home Equity lines of credit, thirty months. COVID-19 has impacted the finances of consumers from layoffs and furloughs resulting from employers that must reduce or suspend operations. Increased risk in this segment includes consumer ability to make mortgage and rent payments. Some of this impact has been offset by governmental actions such as stimulus payments and extended unemployment benefits. First Mid Bank has also offered short-term loan payment deferral to borrowers in this segment. Overall, the historical loss rate for this segment increased slightly for the period however there was no change in the qualitative factor. Commercial Real Estate Loans. The average life of the commercial real estate segment was determined to be thirty-six months. This segment includes the Company's majority of exposure to the hotel industry which has been significantly impacted by COVID-19 events. Other impacted industries in this segment include restaurants and retail establishments. First Mid Bank has implemented a deferral program for borrowers in this segment in order to ease the impact to these borrowers. There was a slight increase in the historical loss rate, however the qualitative factor for this segment was not changed. Agricultural Loans. The average life of the agricultural segment was determined to be eighteen months. Losses in this segment are very low and it is believed that borrowers in this segment will benefit from current governmental programs such as PPP and MFP. Many farmers are holding grain from the 2019 operating season and should be able to take advantage of an increase in prices. In addition to a slight decrease in the historical loss rate, the qualitative factor of this segment was decreased to reflect the improvement in the overall agriculture economy. Commercial The average life of the commercial and industrial segment was determined to be twenty-four months. The COVID-19 impacts include forced closures and scaled-back services for many industries within this segment including retailers, restaurants and video gaming establishments. Some of this risk is offset by government relief programs as well as, First Mid Bank's payment deferral program. There was a slight decrease in the historical loss rate, however the qualitative factor for this segment was not changed. Consumer Loans. The average life of the consumer segment was determined to be thirty-six months. The financial status of many borrowers has been impacted by COVID-19 events including layoffs and reduced hours. Some of this impact has been offset by government stimulus programs, increased paid leave and increased and extended unemployment benefits, however these benefits are now expiring. Additionally, First Mid Bank has offered a short-term payment deferral program. There was a slight decrease in the historical loss rate, however the qualitative factor for this segment was not changed. Acquired Loans. Prior to January 1, 2020 loans acquired with evidence of credit deterioration since origination and for which it was probable that all contractually required payments would not be collected were considered purchased credit impaired at the time of acquisition. Purchase credit-impaired ("PCI") loans were accounted for under ASC 310-30, Receivables--Loans and Debt Securities Acquired with Deteriorated Credit Quality ("ASC 310-30"), and were initially measured at fair value, which included the estimated future credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for credit losses related to these loans was not carried over and recorded at the acquisition date. The cash flows expected to be collected were estimated using current key assumptions, such as default rates, value of underlying collateral, severity and prepayment speeds. Subsequent to January 1, 2020, loans acquired in a business combination that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchased credit deteriorated (“PCD”) loans. At the For acquired loans not deemed purchased credit deteriorated at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on a level-yield basis over the lives of the related loans. At the acquisition date, an initial allowance for expected credit losses is estimated and recorded as credit loss expense. The subsequent measurement of expected credit losses for all acquired loans is the same as the subsequent measurement of expected credit losses for originated loans. The following tables present the balance in the allowance for credit losses and the recorded investment in loans based on portfolio segment and impairment method as of December 31, 2020, 2019 and 2018 (in thousands): Construction & Land Development Agricultural Real Estate 1-4 Family Residential Properties Commercial Real Estate Agricultural Loans Commercial & Industrial Consumer Loans Total Twelve months ended December 31, 2020 Beginning Balance (prior to adoption of ASC 326) $ 1,146 $ 1,093 $ 1,386 $ 11,198 $ 1,386 $ 9,273 $ 1,429 $ 26,911 Impact of adopting ASC 326 (113 ) 230 756 541 (363 ) 155 466 1,672 Provision for credit loss expense 646 (239 ) 274 8,581 503 5,869 469 16,103 Loans charged off 13 — 393 829 — 1,991 618 3,844 Recoveries collected — — 299 169 — 179 421 1,068 Ending balance $ 1,666 $ 1,084 $ 2,322 $ 19,660 $ 1,526 $ 13,485 $ 2,167 $ 41,910 Twelve months ended December 31, 2019 Beginning Balance $ 561 $ 1,246 $ 1,504 $ 11,102 $ 951 $ 9,893 $ 932 $ 26,189 Provision for credit loss expense 585 (153 ) 1,268 1,827 459 1,053 1,394 6,433 Loans charged off — — 1,478 1,743 24 1,828 1,253 6,326 Recoveries collected — — 92 12 — 155 356 615 Ending balance $ 1,146 $ 1,093 $ 1,386 $ 11,198 $ 1,386 $ 9,273 $ 1,429 $ 26,911 Twelve months ended December 31, 2018 Beginning Balance $ 1,202 $ 1,001 $ 886 $ 7,918 $ 743 $ 7,425 $ 802 $ 19,977 Provision for credit loss expense (631 ) 245 1,628 3,353 301 3,155 616 8,667 Loans charged off 10 — 1,111 170 93 832 777 2,993 Recoveries collected — — 101 1 — 145 291 538 Ending balance $ 561 $ 1,246 $ 1,504 $ 11,102 $ 951 $ 9,893 $ 932 $ 26,189 Consistent with regulatory guidance, charge-offs on all loan segments are taken when specific loans, or portions thereof, are considered uncollectible. The Company’s policy is to promptly charge these loans off in the period the uncollectible loss is reasonably determined. For The Company charges-off 1-4 family residential and consumer loans, or portions thereof, when the Company reasonably determines the amount of the loss. The Company adheres to timeframes established by applicable regulatory guidance which provides for the charge-down of 1-4 family first and junior lien mortgages to the net realizable value less costs to sell when the loan is 180 days past due, charge-off of unsecured open-end loans when the loan is 180 days past due, and charge down to the net realizable value when other secured loans are 120 days past due. Loans at these respective delinquency thresholds for which the Company can clearly document that the loan is both well-secured and in the process of collection, such that collection will occur regardless of delinquency status, need not be charged off.

The Company analyzes loans individually by classifying the loans as to credit risk. This analysis is performed on a continuous basis. The Company uses the following definitions for risk ratings, which are commensurate with a loan considered "criticized": Special Mention. Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard. Loans classified as substandard are inadequately protected by the current sound-worthiness and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing factors, conditions and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered pass rated loans.

considered impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. The entire balance of a loan is considered delinquent if the minimum payment contractually required to be made is not received by the specified due date. Impaired loans, excluding certain troubled debt restructured loans, are placed on nonaccrual status. Impaired loans include nonaccrual loans and loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. It is the Company’s policy to have any restructured loans which are on nonaccrual status prior to being modified remain on nonaccrual status until, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collection of interest or principal. If the restructured loan is on accrual status prior to being modified, the loan is reviewed to determine if the modified loan should remain on accrual status.

The accrual of interest is discontinued earlier when, in the opinion of management, there is reasonable doubt as to the timely collection of interest or principal. Once interest accruals are discontinued, accrued but uncollected interest is charged against current year income. Subsequent receipts on non-accrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured. Interest on loans determined to be troubled debt restructurings is recognized on an accrual basis in accordance with the restructured terms if the loan is in compliance with the modified terms. Nonaccrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collection of interest or principal. The Company requires a period of satisfactory performance of not less than six months before returning a nonaccrual loan to accrual status.

The collateral is held by a third party financial institution in the counterparty's custodial account. The counterparty has the right to sell or repledge the investment securities. For government entity repurchase agreements, the collateral is held by the Company in a segregated custodial account under a tri- party agreement. The Company is required by the counterparty to maintain adequate collateral levels. In the event the collateral fair value falls below stipulated levels, the Company will pledge additional securities. The Company closely monitors collateral levels to ensure adequate levels are maintained, while mitigating the potential of over-collateralization in the event of counterparty default. Repurchase agreements by class of collateral pledged are as follows (in thousands): December 31, 2020 December 31, 2019 US Treasury securities and obligations of U.S. government corporations & agencies $ 37,423 $ 77,333 Obligations of states and political subdivisions — 2,375 Mortgage-backed securities: GSE: residential 168,480 128,401 Miscellaneous 1,034 — Total $ 206,937 $ 208,109 At December 31, 2020, there was no outstanding loan balance on the revolving credit agreement with The Northern Trust Company. This loan was renewed on On October 6, 2020, the Company issued and sold $96.0 million in aggregate principal amount of its 3.95% Fixed-to-Floating Rate Subordinated Notes due 2030 (the “Notes”). The Notes were issued pursuant to the Indenture, dated as of October 6, 2020 (the “Base Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture, dated as of October 6, 2020 (the “Supplemental Indenture”), between the Company and the Trustee. The Base Indenture, as amended and supplemented by the Supplemental Indenture, governs the terms of the Notes and provides that the Notes are unsecured, subordinated debt obligations of the Company and will mature on October 15, 2030. From and including the date of issuance to, but excluding October 15, 2025, the Notes will bear interest at an initial rate of 3.95% per annum. From and including October 15, 2025 to, but excluding the maturity date or earlier redemption, the Notes will bear interest at a floating rate equal to three-month Term SOFR plus a spread of 383 basis points, or such other rate as determined pursuant to the Supplemental Indenture, provided that in no event shall the applicable floating interest rate be less than zero per annum. The Company may, beginning with the interest payment date of October 15, 2025, and on any interest payment date thereafter, redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to but excluding the date of redemption. The Company may also redeem the Notes at any time, including prior to October 15, 2025, at the Company’s option, in whole but not in part, if: (i) a change or prospective change in law occurs that could prevent the Company from deducting interest payable on the Notes for U.S. federal income tax purposes; (ii) a subsequent event occurs that could preclude the Notes from being recognized as Tier 2 capital for regulatory capital purposes; or (iii) the Company is required to register as an investment company under the Investment Company Act of 1940, as amended; in each case, at a redemption price equal to 100% of the principal amount of the Notes plus any accrued and unpaid interest to but excluding the redemption date. The Company had approximately $1.8 million of costs, including a debt issuance discount of $1.4 million, in connection with the debt issuance. This expense is being amortized to interest expense over the life of the notes. At December 31, 2020, the recorded balance of subordinated notes was $94,253,000. On February 27, 2004, the Company completed the issuance and sale of $10 million of floating rate trust preferred securities through Trust I, a statutory business trust and wholly-owned unconsolidated subsidiary of the Company, as part of a pooled offering. On October 7, 2019, these trust preferred securities any, On April 26, 2006, the Company completed the issuance and sale of $10 million of fixed/floating rate trust preferred securities through Trust II, a statutory business trust and wholly-owned unconsolidated subsidiary of the Company, as part of a pooled offering. The Company established Trust II for the purpose of issuing the trust preferred securities. The $10 million in proceeds from the trust preferred issuance and an additional $310,000 for the Company’s investment in common equity of Trust II, a total of $10,310,000, was invested in junior subordinated debentures of the Company. The underlying junior subordinated debentures issued by the Company to Trust II mature in 2036, bore interest at a fixed rate of 6.98% paid quarterly until June 15, 2011 and then converted to floating rate (LIBOR plus 160 basis points) after June 15, 2011 (1.82% and 3.49% at December 31, 2020 and 2019). The net proceeds to the Company were used for general corporate purposes, including the Company’s acquisition of Mansfield. On September 8, 2016, the Company assumed the trust preferred securities of Clover Leaf Statutory Trust I (“CLST I”), a statutory business trust that was a wholly owned unconsolidated subsidiary of First Clover Financial. The $4 million of trust preferred securities and an additional $124,000 additional investment in common equity of CLST I, is invested in junior subordinated debentures issued to CLST I. The subordinated debentures mature in 2025, bear interest at three-month LIBOR plus 185 basis points (2.07% and 3.74% at December 31, 2020 and 2019, respectively) and resets quarterly. On May 1, 2018, the Company assumed the trust preferred securities of FBTC Statutory Trust I (“FBTCST I”), a statutory business trust that was a wholly owned The trust preferred securities issued by Trust II, CLST I, and FBTCSTI are included as Tier 1 capital of the Company for regulatory capital purposes. On March In addition to requirements of the Dodd-Frank Act discussed above, the act also required the federal banking agencies to adopt rules that prohibit banks and their affiliates from engaging in proprietary trading and investing in and sponsoring certain unregistered investment companies (defined as hedge funds and private equity funds). This rule is generally referred to as the “Volcker Rule.” On December 10, 2013, the federal banking agencies issued final rules to implement the prohibitions required by the Volcker Rule. Following the publication of the final rule, and in reaction to concerns in the banking industry regarding the adverse impact the final rule’s treatment of certain collateralized debt instruments has on community banks, the federal banking agencies approved an interim final rule to permit banking entities to retain interests in certain collateralized debt obligations backed primarily by trust preferred securities. Under the interim final rule, the agencies permit the retention of an interest in or sponsorship of covered funds by banking entities under $15 billion in assets if (1) the collateralized debt obligation was established and issued prior to May 19, 2010, (2) the banking entity reasonably believes that the offering proceeds received by the collateralized debt obligation were invested primarily in qualifying trust preferred collateral, and (3) the banking entity’s interests in the collateralized debt obligation was acquired on or prior to December 10, 2013. Although the Volcker Rule impacts many large banking entities, the

Regulatory Capital [Abstract]
Regulatory Capital	Note 10 -- Regulatory Capital The Company is subject to various regulatory capital requirements administered by the federal banking agencies. Bank holding companies follow minimum regulatory requirements established by the Board of Governors of the Federal Reserve System (“Federal Reserve System”), and First Mid Bank follow similar minimum regulatory requirements established for national banks by the Office of the Comptroller of the Currency (“OCC”). Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary action by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Quantitative As of December 31, 2020 and 2019, the most recent notification from the primary regulators categorized First Mid Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, minimum total risk-based capital, Tier 1 risk-based capital, Common Equity Tier 1 risk-based capital, and Tier 1 leverage ratios must be maintained as set forth in the table below. At December 31, 2020, there were no conditions or events since the most recent notification that management believes have changed this categorization.

Fair Value Disclosures [Abstract]
Disclosures of Fair Values of Financial Instruments	Note 11 -- Disclosures of Fair Values of Financial Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of three levels of inputs that may be used to measure fair value: Level 1 Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third party pricing services for identical or comparable assets or liabilities which use observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in active markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Following is a description of the inputs and valuation methodologies used for assets measured at fair value on a recurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. Available-for-Sale Securities. The fair value of available-for-sale securities is determined by various valuation methodologies. Where quoted market prices are available in an active market, securities are classified within Level 1. If quoted market prices are not available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market- based or independently sources market parameters, including but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows. Such securities are classified in Level 2 of the valuation hierarchy. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Equity Securities. The fair value of current equity securities is determined by obtaining quoted market prices in an active market and are classified within Level 1. In cases where quoted market prices are not available, fair values are estimated by using quoted prices of securities with similar characteristics and are classified in Level 2 of the valuation hierarchy. Derivatives. The fair value of derivatives is based on models using observable market data as of the measurement date and are therefore classified in Level 2 of the valuation hierarchy. The following table presents the Company’s assets that are measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall as of December 31, 2020 and 2019 (in thousands): Fair Value Measurements Using: Quoted Prices in Significant Significant Active Markets Other Unobservable for Identical Observable Inputs Fair Value Assets (Level 1) Inputs (Level 2) (Level 3) December 31, 2020 Available-for-sale securities: U.S. Treasury securities and obligations of U.S. government corporations and agencies $ 127,069 $ — $ 127,069 $ — Obligations of states and political subdivisions 249,844 — 249,050 794 Mortgage-backed securities 491,348 — 491,348 — Other securities 10,979 — 10,979 — Total available-for-sale securities 879,240 — 878,446 794 Equity securities 218 218 193 — Derivative assets: interest rate swaps 1,399 — 1,399 — Total assets $ 880,857 $ 218 $ 880,038 $ 794 Derivative liabilities: interest swaps $ 2,892 $ — $ 2,892 $ — December 31, 2019 Available-for-sale securities: U.S. Treasury securities and obligations of U.S. government corporations and agencies $ 107,320 $ — $ 107,320 $ — Obligations of states and political subdivisions 178,433 — 177,460 973 Mortgage-backed securities 396,126 — 396,126 — Other securities 3,757 — 3,757 — Total available-for-sale securities 685,636 — 684,663 973 Equity securities 412 219 193 0 Total assets $ 686,048 $ 219 $ 684,856 $ 973 Derivative liabilities: interest swaps $ 325 $ — $ 325 $ — The change in fair value of assets measured on a recurring basis using significant unobservable inputs (Level 3) for the years ended December 31, 2020 and 2019 is summarized as follows (in thousands): Obligations of State and Political Subdivisions December 31, 2020 December 31, 2019 Beginning balance $ 973 $ 967 Transfers into Level 3 — — Transfers out of Level 3 — — Total gains or losses Included in net income 5 6 Included in other comprehensive income (loss) — — Purchases, issuances, sales and settlements Purchases — — Issuances — — Sales — — Settlements (184 ) — Ending balance $ 794 $ 973 Total gains or losses for the period included in net income attributable to the change in unrealized gains or losses related to assets and liabilities still held at the reporting date $ — $ — Following is a description of the valuation methodologies used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. Impaired Loans (Collateral Dependent) Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment. Allowable methods for determining the amount of impairment and estimating fair value include using the fair value of the collateral for collateral dependent loans. If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. Impaired loans that are collateral dependent are classified within Level 3 of the fair value hierarchy when impairment is determined using the fair value method. Management establishes a specific allowance for loans that have an estimated fair value that is below the carrying value. The total carrying amount of loans for which a change in specific allowance has occurred as of December 31, 2020 was $16,789,000 and a fair value of $14,876,000 resulting in specific loss exposures of $1,913,000. As of December 31, 2019, the total carrying amount of loans for which a change specific allowance has occurred was $13,775,000. These loans had a fair value of $12,727,000 which resulted in specific loss exposures of $1,047,600. When there is little prospect of collecting principal or interest, loans, or portions of loans, may be charged-off to the allowance for credit losses. Losses are recognized in the period an obligation becomes uncollectible. The recognition of a loss does not mean that the loan has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the loan even though partial recovery may be affected in the future. Foreclosed Assets Held For Sale Other real estate owned acquired through loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. The adjustment at the time of foreclosure is recorded through the allowance for credit losses. Due to the subjective nature of establishing the fair value when the asset is acquired, the actual fair value of the other real estate owned or foreclosed asset could differ from the original estimate. If it is determined that fair value declines subsequent to foreclosure, a valuation allowance is recorded through noninterest expense. Operating costs associated with the assets after acquisition are also recorded as noninterest expense. Gains and losses on the disposition of other real estate owned and foreclosed assets are netted and posted to other noninterest expense. The total carrying amount of other real estate owned as of December 31, 2020 was $2,489,000. Other real estate owned included in the total carrying amount and measured at fair value on a nonrecurring basis during the period amounted to Mortgage Servicing Rights As of December 31, 2020, mortgage servicing rights had a carrying value of $1,098,000 and a fair value of $516,000 resulting in a valuation reserve of $581,000. As of December 31, 2019, mortgage servicing rights had a carrying value of $1,690,000 and a fair value of $1,444,000 resulting in a valuation reserve of $245,000. The fair value used to determine the valuation reserve for mortgage servicing rights was estimated using the discounted cash flow models. Due to the nature of the valuation inputs, mortgage servicing rights are classified within Level 3 of the fair value hierarchy.

Deferred Compensation Plan [Abstract]
Deferred Compensation Plan	Note 12 -- Deferred Compensation Plan The Company follows the provisions of ASC 710, for purposes of the First Mid-Illinois Bancshares, Inc. Deferred Compensation Plan (“DCP”). At December 31, 2020, the Company classified the cost basis of its common stock issued and held in trust in connection with the DCP of approximately $4,241,000 as treasury stock. The Company also classified the cost basis of its related deferred compensation obligation of approximately $4,241,000 as an equity instrument (deferred compensation). The DCP was effective as of June 1984. The purpose of the DCP is to enable directors, advisory directors, and key employees the opportunity to defer a portion of the fees and cash compensation paid by the Company as a means of maximizing the effectiveness and flexibility of compensation arrangements. The Company invests all participants’ deferrals in shares of common stock. Dividends paid on the shares are credited to participants’ DCP accounts and invested in additional shares. During 2020 and 2019 the Company issued 12,921 common shares and 11,072 common shares, respectively, pursuant to the DCP. The Company also maintains deferred compensation arrangements that were acquired in the Soy Capital acquisition. Individual participants in the agreements are primarily business development employees in the First Mid Insurance and First Mid Wealth Management divisions. The total liabilities associated with these agreements are included in other liabilities on the Company's consolidated balance sheets as of December 31, 2020 and 2019.

Statutory Accounting Practices Statutory Amount Available For Dividend Payments [Abstract]
Dividend Restrictions	Note 16 -- Dividend Restrictions The National Bank Act imposes limitations on the amount of dividends that may be paid by a national bank, such as First Mid Bank. Generally, a national bank may pay dividends out of its undivided profits, in such amounts and at such times as the bank’s board of directors deems prudent. Without prior OCC approval, however, a national bank may not pay dividends in any calendar year which, in the aggregate, exceed the bank’s year-to-date net income plus the bank’s adjusted retained net income for the two preceding years. Factors that could adversely affect First Mid Bank’s net income include other-than- temporary impairment on investment securities that result in credit losses and economic conditions in industries where there are concentrations of loans outstanding that result in impairment of these loans and, consequently loan charges and the need for increased allowances for losses. See “Item 1A. Risk Factors,” Note 4 – “Investment Securities” and Note 5 – “Loans” for a more detailed discussion of the factors. The payment of dividends by any financial institution or its holding company is affected by the requirement to maintain adequate capital pursuant to applicable capital adequacy guidelines and regulations, and a financial institution generally is prohibited from paying any dividends if, following payment thereof, the institution would be undercapitalized. As described above, First Mid Bank exceeded their minimum capital requirements under applicable guidelines as of December 31, 2020. As of December 31, 2020, approximately $46.2 million was available to be paid as dividends to the Company by First Mid Bank. Notwithstanding the availability of funds for dividends, however, the OCC may prohibit the payment of any dividends by First Mid Bank if the OCC determines that such payment would constitute an unsafe or unsound practice.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Note 17 -- Commitments and Contingent Liabilities First Mid Bank enters into financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include lines of credit, letters of credit and other commitments to extend credit. Each of these instruments involves, to varying degrees, elements of credit, interest rate and liquidity risk in excess of the amounts recognized in the consolidated balance sheets. The Company uses the same credit policies and requires similar collateral in approving lines of credit and commitments and issuing letters of credit as it does in making loans. The exposure to credit losses on financial instruments is represented by the contractual amount of these instruments. However, the Company does not anticipate any losses from these The off-balance sheet financial instruments whose contract amounts represent credit risk at December 31, 2020 and 2019 were as follows (in thousands): 2020 2019 Unused commitments and lines of credit: Commercial real estate $ 56,309 $ 122,479 Commercial operating 396,345 308,393 Home equity 40,464 38,933 Other 112,327 103,912 Total $ 605,445 $ 573,717 Standby letters of credit $ 10,048 $ 11,535 Commitments to originate credit represent approved commercial, residential real estate and home equity loans that generally are expected to be funded within ninety days. Lines of credit are agreements by which the Company agrees to provide a borrowing accommodation up to a stated amount as long as there is no violation of any condition established in the loan agreement. Both commitments to originate credit and lines of credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the lines and some commitments are expected to expire without being drawn upon, the total amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by the Company to guarantee the financial performance of customers to third parties. Standby letters of credit are primarily issued to facilitate trade or support borrowing arrangements and generally expire in one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending credit facilities to customers. The maximum amount of credit that would be extended under letters of credit is equal to the total off-balance sheet contract amount of such instrument at December 31, 2020 and 2019. The Company's deferred revenue under standby letters of credit was nominal. The Company is also subject to claims and lawsuits that arise primarily in the ordinary course of business. It is the opinion of management that the disposition

In addition, immediately prior to the closing of the proposed merger, LINCO paid a special dividend to its shareholders in the aggregate amount of $13 million. The Merger closed on February 22, 2021 . Disclosures could not be made as the initial accounting is incomplete.

Leases [Abstract]
Leases	Note 20 -- Leases Effective January 1, 2019, the Company adopted ASU 2016-02 Leases (Topic 842). As of December 31, 2020, substantially all of the Company's leases are operating leases for real estate property bank branches, ATM locations, and office space. These leases are generally for periods of 1 to 25 years with various renewal options. The Company elected the optional transition method permitted by Topic 842. Under this method, an entity recognizes and measures leases that exist at the application date and prior comparative periods are not adjusted. In addition, the Company elected the package of practical expedients: 1. An 2. An 3. An entity need to reassess initial direct costs for any existing The Company also elected the practical expedient, which may be elected separately or in conjunction with the package noted above, to use hindsight in determining the lease term and in assessing the right-of-use assets. This expedient must be applied consistently to all leases. Lastly, the Company has elected to use the practical expedient to include both lease and non-lease components as a single component and account for it as a lease. In addition, the Company has elected not to include short-term leases (i.e. leases with terms of twelve months or less) or equipment leases (primarily copiers) deemed immaterial, on the consolidated balance sheets. For leases in effect at January 1, 2019 and for leases commencing thereafter, the Company recognizes a lease liability and a right-of-use asset, based on the present value of lease payments over the lease term. The discount rate used in determining the present value was the Company's incremental borrowing rate which is the FHLB fixed advance rate based on the remaining lease term as of January 1, 2019, or the commencement date for leases subsequently entered into. The following table contains supplemental balance sheet information related to leases (dollars in thousands): 2020 2019 Operating lease right-of-use assets $ 17,209 $ 17,006 Operating lease liabilities 17,351 17,007 Weighted-average remaining lease term 7.3 years 7.3 years Weighted-average discount rate 2.85 % 3.07 % Certain of the Company's leases contain options to renew the lease; however, not all renewal options are included in the calculation of lease liabilities as they are not reasonably certain to be exercised. The Company's leases do not contain residual value guarantees or material variable lease payments. The Company does not have any other material restrictions or covenants imposed by leases that would impact the Company's ability to pay dividends or cause the Company to incur additional financial obligations.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Accounting and Consolidation	The accompanying consolidated financial statements include the accounts of First Mid Bancshares, Inc. (“Company”) and its wholly-owned subsidiaries: First Mid Bank & Trust, N.A. (“First Mid Bank”), Mid-Illinois Data Services, Inc. (“MIDS”), First Mid Wealth Management Company, First Mid Insurance Group, Inc. (“First Mid Insurance”) and First Mid Captive, Inc. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts in the prior year’s consolidated financial statements have been reclassified to conform to the 2020 presentation and there was no impact on net income or stockholders’ equity from these reclassifications. The Company operates as a single segment entity for financial reporting purposes. The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America.
COVID-19	COVID-19 The COVID-19 outbreak is an unprecedented event that provides significant economic uncertainty for a broad spectrum of industries. The Company is focused on supporting its customers, communities and employees during this unique operating environment. Throughout this document, the Company describes the impact COVID-19 is having, actions taken as a result of COVID-19, and certain risks to the Company that COVID-19 creates or exacerbates, as well as management's outlook on the current COVID-19 situation.
Acquisition	Acquisition On September 25, 2020, the Company and Eval Sub Inc., wholly-owned subsidiary of the Company ("Merger Sub"), entered into an Agreement and Plan of Merger (the "Merger Agreement") with LINCO Bancshares, Inc., the former parent of Providence Bank ("LINCO"), and the sellers as defined therein, pursuant to which, among other things, the Company agreed to acquire 100% of the issued and outstanding shares of LINCO pursuant to a business combination whereby Merger Sub merged with and into LINCO, whereupon the separate corporate existence of Merger Sub ceased and LINCO continued as the surviving company and a wholly-owned subsidiary of the Company (the "Merger"). Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each share of common stock, par value $1.00 per share, of LINCO issued and outstanding immediately prior to the effective time of the Merger (other than shares held in treasury by LINCO) was converted into and become the right to receive, cash or shares of common stock, par value $4.00 per share, of the Company and cash in lieu of fractional shares, less any applicable taxes required to be withheld, and subject to certain potential adjustments. On an aggregate basis, the total consideration payable by the Company at the closing of the Merger was $103.5 million in cash and 1,262,246 shares of the Company’s common stock, provided that the shareholders of LINCO collectively elected pursuant to the Merger Agreement to receive varying amounts of cash or shares of common stock of the Company as consideration in the Merger. In addition, immediately prior to the closing of the proposed merger, LINCO paid a special dividend to its shareholders in the aggregate amount of $13 million. The Merger closed on February 22, 2021. It is anticipated that Providence Bank will be merged with and into First Mid Bank in the second quarter of 2021. At the time of the bank merger, Providence Bank’s banking offices will become branches of First Mid Bank.
General Litigation	General Litigation The Company is subject to claims and lawsuits that arise primarily in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits will not have a material adverse effect on the consolidated financial position, results of operations and cash flows of the Company.
Loan Purchase	Loan Purchase On April 21, 2020, First Mid Bank completed an acquisition of loans in the St. Louis metro market totaling $183 million. There were no loans purchased with deteriorated credit. Loans Loans are stated at the principal amount outstanding net of unearned discounts, unearned income and the allowance for credit losses. Unearned income includes deferred loan origination fees reduced by loan origination costs and is amortized to interest income over the life of the related loan using methods that approximate the effective interest rate method. Interest on substantially all loans is credited to income based on the principal amount outstanding. The Company’s policy is to discontinue the accrual of interest income on any loan that becomes ninety days past due as to principal or interest or earlier when, in the opinion of management there is reasonable doubt as to the timely collection of principal or interest. Nonaccrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collectability of interest or principal. Loans expected to be sold are classified as held for sale in the consolidated financial statements and are recorded at the lower of aggregate cost or fair value, taking into consideration future commitments to sell the loans.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company uses estimates and employs the judgments of management in determining the amount of its allowance for credit losses and income tax accruals and deferrals, in its fair value measurements of investment securities, and in the evaluation of impairment of loans, goodwill, investment securities, and premises and equipment. As with any estimate, actual results could differ from these estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses. In connection with the determination of the allowance for credit losses, management obtains independent appraisals for significant properties.
Fair Value Measurements	Fair Value Measurements The fair value of a financial instrument is defined as the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The Company estimates the fair value of a financial instrument using a variety of valuation methods. Where financial instruments are actively traded and have quoted market prices, quoted market prices are used for fair value. When the financial instruments are not actively traded, other observable market inputs, such as quoted prices of securities with similar characteristics, may be used, if available, to determine fair value. When observable market prices do not exist, the Company estimates fair value. The Company’s valuation methods consider factors such as liquidity and concentration concerns. Other factors such as model assumptions, market dislocations, and unexpected correlations can affect estimates of fair value. Imprecision in estimating these factors can impact the amount of revenue or loss recorded. At the end of each quarter, the Company assesses the valuation hierarchy for each asset or liability measured. From time to time, assets or liabilities may be transferred within hierarchy levels due to changes in availability of observable market inputs to measure fair value at the measurement date. Transfers into or out of hierarchy levels are based upon the fair value at the beginning of the reporting period. A more detailed description of the fair values measured at each level of the fair value hierarchy can be found in Note 11 – “Disclosures of Fair Values of Financial Instruments.”
Cash and Cash Equivalents and Certificates of Deposit Investments	Cash and Cash Equivalents For purposes of reporting cash flows, cash equivalents include non-interest bearing and interest-bearing cash and due from banks and federal funds sold. Generally, federal funds are sold for one-day Certificates of Deposit Investments Certificates of deposit investments have original maturities of three to five years and are carried at cost.
Investment Securities	Investment Securities The Company classifies its investments in debt securities as either held-to-maturity or available-for-sale in accordance with ASC 320. Securities classified as held-to-maturity are recorded at cost or amortized cost. Available-for-sale securities are carried at fair value. Fair value calculations are based on quoted market prices when such prices are available. If quoted market prices are not available, estimates of fair value are computed using a variety of techniques, including extrapolation from the quoted prices of similar instruments or recent trades for thinly traded securities, fundamental analysis, or through obtaining purchase quotes. Due to the subjective nature of the valuation process, it is possible that the actual fair values of these investments could differ from the estimated
Allowance for Credit Losses	Allowance for Credit Losses The Company believes the allowance for credit losses is the critical accounting policy that requires the most significant judgments and assumptions used in the The Company estimates the appropriate level of allowance for credit losses by separately evaluating impaired and nonimpaired loans. A specific allowance is assigned to an impaired loan when expected cash flows or collateral do not justify the carrying amount of the loan. The methodology used to assign an allowance to a nonimpaired loan is more subjective. Generally, the allowance assigned to nonimpaired loans is determined by applying historical loss rates to existing loans with similar risk characteristics, adjusted for qualitative factors including the volume and severity of identified classified loans, changes in economic conditions, changes in credit policies or underwriting standards, and changes in the level of credit risk associated with specific industries and markets. Because the economic and business climate in any given industry or market, and its impact on any given borrower, can change rapidly, the risk profile of the loan portfolio is continually assessed and adjusted when appropriate. Notwithstanding these procedures, there still exists the possibility that the assessment could prove to be significantly incorrect and that an immediate adjustment to the allowance for credit losses would be required.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is charged to expense and determined principally by the straight-line method over the estimated useful lives of the assets. The estimated useful lives for each major depreciable classification of premises and equipment are as follows: Buildings 20 years to 40 years Leasehold 5 years to 15 years Furniture 3 years to 7 years
Goodwill and Intangible Assets	Goodwill and Intangible Assets The Company has goodwill from business combinations, identifiable intangible assets assigned to core deposit relationships and customer lists acquired, and intangible assets arising from the rights to service mortgage loans for others. Identifiable intangible assets generally arise from branches acquired that the Company accounted for as purchases. Such assets consist of the excess of the In accordance with the provisions of SFAS No. 142, “ Goodwill and Other Intangible Assets
Other Real Estate Owned	Other Real Estate Owned Other real estate owned acquired through loan foreclosure is initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. The adjustment at the time of foreclosure is recorded through the allowance for credit losses. Due to the subjective nature of establishing the fair value when the asset is acquired, the actual fair value of the other real estate owned or foreclosed asset could differ from the original estimate. If it is determined that fair value temporarily declines subsequent to foreclosure, a valuation allowance is recorded through noninterest expense. Operating costs associated with the assets after acquisition are also recorded as noninterest expense. Gains and losses on the disposition of other real estate owned and foreclosed assets are netted and posted to other noninterest expense.
Bank Owned Life Insurance	Bank Owned Life Insurance First Mid Bank has purchased life insurance policies on certain senior management. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts that are probable at settlement.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock Federal Home Loan Bank stock is a required investment for institutions that are members of the Federal Home Loan Bank system. The required investment in the common stock is based on a predetermined formula.
Income Taxes	Income Taxes The Deferred tax assets and liabilities are recognized for future tax consequences attributable to the temporary differences existing between the financial statement carrying amounts of assets and liabilities and their respective tax basis, as well as operating loss and tax credit carry forwards. To the extent that current available evidence about the future raises doubt about the realization of a deferred tax asset, a valuation allowance is established. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as an increase or decrease in income tax expense in the period in which such change is enacted. Additionally, the Company reviews its uncertain tax positions annually under FASB Interpretation No. 48 (FIN No. 48), “ Accounting for Uncertainty in Income Taxes ,”
Captive Insurance Company	Captive Insurance Company First Mid Captive, Inc. ("the Captive"), a wholly-owned subsidiary of the Company which was formed and began operations in December 2019, is a Nevada- based captive insurance company. The Captive insures against certain risks unique to the operations of the Company and its subsidiaries for which insurance may not be currently available or economically feasible in today's insurance marketplace. The Captive pools resources with several other similar insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. The Captive is subject to regulations of the State of Nevada and undergoes periodic examinations by the Nevada Division of Insurance. It has elected to be taxed under Section 831(b) of the Internal Revenue Code. Pursuant to Section 831(b), if gross premiums do not exceed $2,300,000, then the Captive is taxable solely on its investment income. The Captive is included in the Company's consolidated financial statements and its federal income return.
Trust Assets	Trust Assets Assets held in fiduciary or agency capacities by First Mid Wealth Management Company are not included in the consolidated balance sheets since such items are not assets of the Company or its subsidiaries. Fees from trust activities are recorded on a cash basis over the period in which the service is provided. Fees are a function of the market value of assets managed and administered, the volume of transactions, and fees for other services rendered, as set forth in the underlying client agreement with the First Mid Wealth Management Company. This revenue recognition involves the use of estimates and assumptions, including components that are calculated based on asset valuations and transaction volumes. Any out of pocket expenses or services not typically covered by the fee schedule for trust activities are charged directly to the trust account on a gross basis as trust revenue is incurred. At December 31, 2020, the First Mid Wealth Management Company managed or administered 1,411 trust accounts with assets totaling approximately $1,563.0 million. At December 31, 2019, the Company managed or administered 1,635 trust accounts with assets totaling approximately $1,487.5 million.
Treasury Stock	Treasury Stock Treasury stock is stated at cost. Cost is determined by the first-in, first-out method.
Stock Incentive Awards	Stock Incentive Awards At ten-year A maximum of 149,983 shares of common stock may be issued under the SI Plan. The Company awarded 25,950, 26,700, and 28,700 shares during 2020, 2019, and 2018, respectively as stock and stock unit awards.
Employee Stock Purchase Plan	Employee Stock Purchase Plan At ESPP. 2020 and the ESPP.
Leases	Leases Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic ATM
Revenue Recognition	Revenue Recognition Accounting Revenue from Contracts with Customers Trust revenues. The Company generates fee income from providing fiduciary services through its trust department. Fees are billed in arrears based upon the preceding period account balance. Revenue from the farm management department is recorded when service is complete, for example when crops are sold. Brokerage commissions. The primary brokerage revenue is recorded at the beginning of each quarter through billing to customers based on the account asset size on the last day of the previous quarter. If a withdrawal of funds takes place, a prorated refund may occur; this is reflected within the same quarter as the original billing occurred. All performance obligations are met within the same quarter that the revenue is recorded. Insurance commissions. The Company’s insurance agency subsidiary, First Mid Insurance, receives commissions on premiums of new and renewed business policies. First Mid Insurance records commission revenue on direct bill policies as the cash is received. For agency bill policies, First Mid Insurance retains its commission portion of the customer premium payment and remits the balance to the carrier. In both cases, the entire performance obligation is held by the carriers. Service charges on deposits. The Company generates revenue from fees charged for deposit account maintenance, overdrafts, wire transfers, and check fees. The revenue related to deposit fees is recognized at the time the performance obligation is satisfied. ATM/debit card revenue. The Company generates revenue through service charges on the use of its ATM machines and interchange income from the use of Company issued credit and debit cards. The revenue is recognized at the time the service is used and the performance obligation is satisfied. Other income. Treasury management fees and lock box fees are received and recorded after the service performance obligation is completed. Merchant bank card fees are received from various vendors, however the performance obligation is with the vendors. The Company records gains on the sale of loans and the sale of OREO properties after the transactions are complete and transfer of ownership has occurred. As each of the Company’s facilities is located in markets with similar economies, no disaggregation of revenue is necessary.
Adoption of New Accounting Guidance	Adoption of New Accounting Guidance Accounting Standards Update 2017-04, Intangibles-Goodwill and Other (Topic 350: Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). In January 2017, FASB issued ASU 2017-04. The amendments in this update simplify the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under this guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for public companies for the reporting periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Although the Company cannot anticipate future goodwill impairment, based on the most recent assessment, it is unlikely that an impairment amount would need to be calculated and, therefore, does not anticipate a material impact on the Company's financial statements. The current accounting policies and procedures of the Company did not change, except for the elimination of Step 2 analysis. Accounting Standards Update 2016-02, Leases (Topic 842)("ASU 2016-02"). On February 25, 2016, FASB issued ASU 2016-02 which creates Topic 842, Leases and supersedes Topic 840, Leases. ASU 2016-02 is intended to improve financial reporting about leasing transactions, by increasing transparency and comparability among organizations. Under the new guidance, a lessee is required to record all leases with lease terms of more than 12 months on their balance sheet as lease liabilities with a corresponding right-of-use asset. ASU 2016-02 maintains the dual model for lease accounting, requiring leases to be classified as either operating or finance, with lease classification determined in a manner similar to existing lease guidance. The new guidance is effective for public companies for fiscal years beginning on or after December 15, 2018, and for private companies for fiscal years beginning on or after December 15, 2019. The Company adopted the guidance effective January 1, 2019 and recorded a right of use asset of $14.1 million and a lease liability of $14.1 million. Accounting Standards Update 2018-13, Fair Value Measurements (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). In August 2018, FASB issued ASU 2018-13. This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, an entity will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019. As ASU 2018-13 only revises disclosure requirements, it did not have a material impact on the Company’s consolidated financial statements. Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments (“ASU 2016-13”). In June 2016, FASB issued ASU 2016-13. The provisions of ASU 2016-13 requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime "expected credit loss" and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. ASU 2016-13 also requires new disclosures for financial assets measured at amortized cost, loans and available-for- sale debt securities. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Management formed an internal, cross functional committee in 2017 to evaluate implementation steps and assess the impact ASU 2016-13 would have on the Company’s consolidated financial statements. The committee assigned roles and responsibilities, key tasks to complete, and established a general time-line for implementation. The Company also engaged an The Company adopted ASU 2016-13 using the modified retrospective method for financial assets measured at amortized cost-effective January 1, 2020. Results for the periods beginning after January 1, 2020 are presented under ASU 2016-13 while prior period amounts are reported in accordance with the previously applicable accounting standards. The Company recorded a reduction to retained earnings of approximately $717,000 upon adoption of ASU 2016-13. The transition adjustment included an increase to the allowance for credit losses on loans of $1.7 million and an increase to the allowance for credit losses on off-balance sheet credit exposure of $69,000. There was no allowance for credit losses recorded for held-to- maturity debt securities. The transition adjustment included corresponding increases in deferred tax assets. The Company adopted ASU 2016-13 using the prospective transition approach for financial assets considered purchased credit deteriorated ("PCD") that were previously classified as purchase credit impaired ("PCI") and accounted for under ASC 310-30 effective January 1, 2020. In accordance with the standard, the Company did not reassess whether the PCI assets met the criteria of PCD assets as of the adoption date. The amortized cost of the PCD assets were adjusted to reflect the addition of $833,000 to the allowance for credit losses.
