Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Accounting and Consolidation	Note 1 -- Basis of Accounting and Consolidation The unaudited condensed consolidated financial statements include the accounts of First Mid Bancshares, Inc. (“Company”) formerly known as First Mid-Illinois Bancshares, Inc., and its wholly owned subsidiaries: First Mid Bank & Trust, N.A. (“First Wealth The unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and do not include all of the information required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements and related footnote disclosures although the Company believes that the disclosures made are adequate to make the information not misleading. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2019 Annual Report on Form 10-K. 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, we describe 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. 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 8 Stock Plans At ten-year A maximum of 149,983 shares of common stock may be issued under the SI Plan. There have been no stock options awarded under 25,200 25,950 Employee Stock Purchase Plan At the Annual Meeting of Stockholders held April 25, 2018, the stockholders approved the First Mid-Illinois Bancshares, Inc. Employee A 600,000 ESPP. 7,543 ESPP. Captive Insurance Company First “ 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. Revenue Recognition Accounting Revenue from Contracts with Customers Trust revenues. The Company generates fee income from providing fiduciary services through its subsidiary, First Mid Wealth Management Company. 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. 9 Brokerage commissions. The primary non-farm 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 in markets with similar economies, no disaggregation of revenue is necessary. Leases Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842). As of June 30, 2020, all of the Company's leases are operating leases for real estate property for bank branches, ATM locations, and office space. 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 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. Accumulated Other Comprehensive Income The components of accumulated other comprehensive income included in stockholders’ equity as of June 30, 2020 and December 31, 2019 are as follows (in Unrealized Gain (Loss) on Securities June 30, 2020 Net unrealized gains on securities available-for-sale $ 24,107 Unamortized losses on held-to-maturity securities transferred from available-for-sale (15 ) Tax expense (6,987 ) Balance at June 30, 2020 $ 17,105 December 31, 2019 Net unrealized gains on securities available-for-sale $ 11,825 Unamortized losses on held-to-maturity securities transferred from available-for-sale (50 ) Tax expense (3,415 ) Balance at December 31, 2019 $ 8,360 10 Amounts reclassified from accumulated other comprehensive income and the affected line items in the statements of income during the three and six months ended June 30, 2020 and 2019 , were as follows (in thousands): Amounts Reclassified from Other Comprehensive Income Three months ended June 30, Six months ended June 30, 2020 2019 2020 2019 Affected Line Item in the Statements of Income Realized gains on available-for-sale securities $ 287 $ 218 $ 818 $ 272 Securities gains, net Tax effect (83 ) (63 ) (237 ) (79 ) Income taxes Total reclassifications out of accumulated other comprehensive income $ 204 $ 155 $ 581 $ 193 Net reclassified amount See “Note 3 – Investment Securities” for more detailed information regarding unrealized losses on available-for-sale securities. 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. The Company adopted the guidance effective January 2020. Although the Company cannot anticipate future goodwill impairment, the Company does not anticipate a material impact on the Company's financial statements. The current accounting policies and procedures of the Company have not changed, 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 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. Entities will apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. 11 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 outside consultant to assist with the methodology review and data validation, as well as other key aspects of implementing the standard. The committee met periodically to discuss the latest developments and ensure progress was being made. In addition, the committee kept current on evolving interpretations and industry practices related to ASU 2016-13. The committee evaluated and validated data resources and different loss methodologies. Key implementation activities for 2019 included finalization of models, establishing processes and controls, development of supporting analytics and documentation, policies and disclosure, and implementing parallel processing. 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.

At December 31, 2019 there were fourteen mortgage-backed securities with a fair value of $20,888,000 and unrealized losses of $190,000 in a continuous unrealized loss position for twelve months or more. The Company does not believe any unrealized losses as of June 30, 2020 represents other than temporary impairment ("OTTI"). However, given the uncertainty of the financial markets, the Company may be required to recognize OTTI losses in future periods with respect to its available for sale investment securities portfolio. The amount and timing of any additional OTTI will depend on the decline in the underlying cash flows of the securities. Should the impairment of any of these securities become other-than-temporary, the cost basis of the investment will be reduced, and the resulting loss recognized in the period the other-than-temporary impairment is identified.

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 The Company’s policy is to discontinue the accrual of interest income on all loans for which principal or interest" id="sjs-B4">Note 4 – Loans and Allowance for Loan Losses Loans are stated at amortized cost net of an allowance for credit losses. Amortized cost is the unpaid principal net of unearned premiums and discounts, and net deferred origination fees and costs. Deferred loan origination fees are reduced by loan origination costs and are 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. A summary of loans at June 30, 2020 and December 31, 2019 follows (in thousands): June 30, 2020 December 31, 2019 Construction and land development $ 181,362 $ 94,462 Agricultural real estate 251,695 240,481 1-4 Family residential properties 341,691 336,553 Multifamily residential properties 140,415 155,132 Commercial real estate 1,125,584 997,175 Loans secured by real estate 2,040,747 1,823,803 Agricultural loans 149,072 136,023 Commercial and industrial loans 818,686 528,987 Consumer loans 81,980 83,544 All other loans 123,937 126,807 Total Gross loans 3,214,422 2,699,164 Less: Loans held for sale 5,981 1,820 3,208,441 2,697,344 Less: Net deferred loan fees, premiums and discounts 9,160 3,817 Allowance for credit losses 38,381 26,911 Net loans $ 3,160,900 $ 2,666,616 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. These loans are primarily for 1-4 family residential properties. Accrued interest on loans, which is excluded from the amortized cost of the balances above, totaled $14.1 million and $12.4 million at June 30, 2020 and December 31, 2019, respectively. 16 Most of the Company’s business activities are with customers located near the Company's branch locations in Illinois and Missouri. At June 30, 2020, the Company’s loan portfolio included $400.8 million of loans to borrowers whose businesses are directly related to agriculture. Of this amount, $330.5 million was concentrated in corn and other grain farming. Total loans to borrowers whose businesses are directly related to agriculture increased $24.4 million from $376.4 million at December 31, 2019 due to seasonal timing of cash flow requirements. Loans concentrated in corn and other grain farming increased $29.0 million from $301.5 million at December 31, 2019. The Company's underwriting practices include collateralization of loans, any extended period of low commodity prices, drought conditions, significantly reduced yields on crops and/or reduced levels of government assistance to the agricultural industry, however these could result in an increase in the level of problem agriculture loans and potentially result in loan losses within the agricultural portfolio. In addition, the Company has $126.5 million of loans to motels and hotels. The performance of these loans is dependent on borrower specific issues as well as the general level of business and personal travel within the region. While the Company adheres to sound underwriting standards, a prolonged period of reduced business or personal travel could result in an increase in nonperforming loans to this business segment and potentially in loan losses. The Company also has $401.5 million of 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 and most borrowers are below regulatory thresholds. The Company can occasionally have outstanding balances to one borrower up to but not exceeding the regulatory threshold should underwriting guidelines warrant. Most of the the Company’s loans are to businesses located in the 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. 17 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 most 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. 18 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 During 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, however, projects may be hampered by COVID-19 restrictions which could increase costs and duration. T he qualitative factor for this segment was increased to account for these potential risks. 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. More pressure on landowners to lower cash rents as farmers struggle to cover expenses is expected which would lower the return to landowners and impact the market value of the land. The qualitative factor for this segment was increased to account for this potential risk. 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. The historical loss rate for this segment declined for the period but was offset by an increase in the qualitative factor to account for these potential risks. 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. While there was a slight decrease in the historical loss rate, the qualitative factor for this segment was increased to account for these risks. 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 waiting for an increase in prices, however, as of June 30, prices were down compared to the beginning of the year. It is now believed that many farmers will likely not be able to cover their operating expenses. The qualitative factor of this segment was increased to account for this new risk. 19 Commercial and Industrial Loans. 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. In addition to an increase in the historical loss rate, the qualitative factor for this segment was increased to account for these new risks. 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. Additionally, First Mid Bank has offered a short-term payment deferral program. While the historical loss rate decreased for this period, the qualitative factor for the segment was increased to account for these risks. 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.

A weighted average of the net losses was determined by assigning more weight to the most recent quarters in order to recognize current risk factors influencing the various segments of the loan portfolio more prominently than past periods. Due to weakened economic conditions during historical years, the Company established qualitative factor adjustments for each of the loan segments at levels above the historical net loss averages. Some of the economic factors included the potential for reduced cash flow for commercial operating loans from reduction in sales or increased operating costs, decreased occupancy rates for commercial buildings, reduced levels of home sales for commercial land developments, the uncertainty regarding grain prices and increased operating costs for farmers, and increased levels of unemployment and bankruptcy impacting consumer’s ability to pay. Each of these economic uncertainties was taken into consideration in developing the level of the allowance for loan losses.

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. 21 The following table presents the amortized cost basis of collateral-dependent loans by class of loans that were individually evaluated to determine expected credit losses, and the related allowance for credit losses, as of June 30, 2020 (in thousands): Collateral Allowance Real Estate Business Assets Other Total for Credit Losses Construction and land development $ 532 $ — $ — $ 532 $ 261 Agricultural real estate — — — — — 1-4 Family residential properties 3,292 — — 3,292 157 Multifamily residential properties 1,960 — — 1,960 — Commercial real estate 6,858 — — 6,858 863 Loans secured by real estate 12,642 0 0 12,642 1,281 Agricultural loans 0 — — 0 — Commercial and industrial loans 301 3,699 18 4,018 88 Consumer loans — — 11 11 — Total loans $ 12,943 $ 3,699 $ 29 $ 16,671 $ 1,369 Credit Quality The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, collateral support, credit documentation, public information, and current economic trends, among other factors. 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, based on 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. 22 The following tables present the credit risk profile of

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 The Company’s policy is to discontinue the accrual of interest income on all loans for which principal or interest

Repurchase Agreements And Other Borrowings [Abstract]
Repurchase Agreements and Other Borrowings	Note 6 -- Repurchase Agreements and Other Borrowings Securities sold under agreements to repurchase were $350.3 million at June 30, 2020, an increase of $142.2 million from $208.1 million at December 31, 2019. The increase during the first three months of 2020 was primarily due to changes in business cash flow needs. All the transactions have overnight maturities with a weighted average rate of 0.22%. The right of setoff for a repurchase agreement resembles a secured borrowing, whereby the collateral pledged by the Company would be used to settle the fair value of the repurchase agreement should the Company be in default (e.g., declare bankruptcy), the Company could cancel the repurchase agreement (i.e., cease payment of principal and interest), and attempt collection on the amount of collateral value in excess of the repurchase agreement fair value. 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.

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	Note 7 -- Fair Value of Assets and Liabilities 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 independent sources of 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. Fair value determinations for Level 3 measurements of securities are the responsibility of the Treasury function of the Company. The Company contracts with a pricing specialist to generate fair value estimates on a monthly basis. The Treasury function of the Company challenges the reasonableness of the assumptions used and reviews the methodology to ensure the estimated fair value complies with accounting standards generally accepted in the United States, analyzes the changes in fair value and compares these changes to internally developed expectations and monitors these changes for appropriateness. 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. 31 The following table presents the Company’s assets and liabilities 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 June 30, 2020 and December 31, 2019 (in thousands): Fair Value Measurements Using Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Fair Value (Level 1) (Level 2) (Level 3) June 30, 2020 Available-for-sale securities: U.S. Treasury securities and obligations of U.S. government corporations and agencies $ 73,899 $ — $ 73,899 $ — Obligations of states and political subdivisions 200,697 — 199,906 791 Mortgage-backed securities 425,674 — 425,674 — Other securities 7,888 — 7,888 — Total available-for-sale securities 708,158 — 707,367 791 Equity securities 97 97 — — Derivative assets: interest rate swaps 42 — 42 — Total assets $ 708,297 $ 97 $ 707,409 $ 791 Derivative liabilities: interest rate swaps $ 1,829 $ — $ 1,829 $ — 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 3,950 — 3,950 — Total available-for-sale securities 685,829 — 684,856 973 Equity securities 219 219 — — Total assets $ 686,048 $ 219 $ 684,856 $ 973 Derivative liabilities: interest rate swaps $ 325 $ — $ 325 $ — 32 The change in fair value of assets measured on a recurring basis using significant unobservable inputs (Level 3) for the three and six months ended June 30, 2020 and 2019 is summarized as follows (in thousands): Obligation of State and Political Subdivisions Three months ended Six months ended June 30, 2020 June 30, 2019 June 30, 2020 June 30, 2019 Beginning balance $ 790 $ 968 $ 973 $ 967 Transfers into Level 3 — — — — Transfers out of Level 3 — — — — Total gains or losses: Included in net income 1 2 2 3 Included in other comprehensive income (loss) — — — — Purchases, issuances, sales and settlements: Purchases — — — — Issuances — — — — Sales — — (184 ) — Settlements — — — — Ending balance $ 791 $ 970 $ 791 $ 970 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 impaired 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 June 30, 2020 was $9,708,000 and a fair value of $8,358,000 resulting in specific loss exposures of $1,350,000. When there is little prospect of collecting principal or interest, loans, or portions of loans, may be charged-off to the allowance for loan 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 loan 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 June 30, 2020 was $2,256,000. Other real estate owned included in the total carrying amount and measured at fair value on a nonrecurring basis during the period amounted to $21,000 33 Mortgage Servicing Rights. As of June 30, 2020, mortgage servicing rights had a carrying value of $1,422,000 and a fair value of $899,000 resulting in a valuation reserve of $523,000. The fair value used to determine the valuation reserve for mortgage servicing rights was estimated using the discounted cash flow models.

Leases [Abstract]
Leases	35 Note 8 -- Leases Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842). As of June 30, 2020, substantially all the Company's leases are operating leases for real estate property for 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, the Company 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 entity need not reassess whether any expired or existing contracts contain 2. An entity need not reassess the lease classification for any expired or existing 3. An entity need not reassess initial direct costs for any existing The Company has 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 to not 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 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.

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.
Revenue Recognition	Revenue Recognition Accounting Revenue from Contracts with Customers Trust revenues. The Company generates fee income from providing fiduciary services through its subsidiary, First Mid Wealth Management Company. 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. 9 Brokerage commissions. The primary non-farm 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 in markets with similar economies, no disaggregation of revenue is necessary.
Leases	Leases Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842). As of June 30, 2020, all of the Company's leases are operating leases for real estate property for bank branches, ATM locations, and office space. 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 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.

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. The Company adopted the guidance effective January 2020. Although the Company cannot anticipate future goodwill impairment, the Company does not anticipate a material impact on the Company's financial statements. The current accounting policies and procedures of the Company have not changed, 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 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. Entities will apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. 11 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 outside consultant to assist with the methodology review and data validation, as well as other key aspects of implementing the standard. The committee met periodically to discuss the latest developments and ensure progress was being made. In addition, the committee kept current on evolving interpretations and industry practices related to ASU 2016-13. The committee evaluated and validated data resources and different loss methodologies. Key implementation activities for 2019 included finalization of models, establishing processes and controls, development of supporting analytics and documentation, policies and disclosure, and implementing parallel processing. 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.

A weighted average of the net losses was determined by assigning more weight to the most recent quarters in order to recognize current risk factors influencing the various segments of the loan portfolio more prominently than past periods. Due to weakened economic conditions during historical years, the Company established qualitative factor adjustments for each of the loan segments at levels above the historical net loss averages. Some of the economic factors included the potential for reduced cash flow for commercial operating loans from reduction in sales or increased operating costs, decreased occupancy rates for commercial buildings, reduced levels of home sales for commercial land developments, the uncertainty regarding grain prices and increased operating costs for farmers, and increased levels of unemployment and bankruptcy impacting consumer’s ability to pay. Each of these economic uncertainties was taken into consideration in developing the level of the allowance for loan losses.
