Notes to Condensed Consolidated Financial Statements

(unaudited)

Note 1 --  Basis of Accounting and Consolidation

The unaudited condensed consolidated financial statements include the accounts of First Mid-Illinois Bancshares, Inc. (“Company”) and its wholly-owned subsidiaries:  First Mid-Illinois Bank & Trust, N.A. (“First Mid Bank”), Mid-Illinois Data Services, Inc. (“MIDS”) and The Checkley Agency, Inc. doing business as First Mid Insurance Group (“First Mid Insurance”).  All significant intercompany balances and transactions have been eliminated in consolidation.   The financial information reflects all adjustments which, in the opinion of management, are necessary for a fair presentation of the results of the interim periods ended March 31, 2018 and 2017, and all such adjustments are of a normal recurring nature.  Certain amounts in the prior year’s consolidated financial statements have been reclassified to conform to the March 31, 2018 presentation and there was no impact on net income or stockholders’ equity.  The results of the interim period ended March 31, 2018 are not necessarily indicative of the results expected for the year ending December 31, 2018. The Company operates as a one-segment entity for financial reporting purposes.

The 2017 year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

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 financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2017 Annual Report on Form 10-K.

Website

The Company maintains a website at www.firstmid.com. All periodic and current reports of the Company and amendments to these reports filed with the Securities and Exchange Commission (“SEC”) can be accessed, free of charge, through this website as soon as reasonably practicable after these materials are filed with the SEC.

At-The-Market Program

On August 16, 2017, the Company entered into a Sales Agency Agreement, pursuant to which the Company may sell, from time to time, up to an aggregate of $20 million of it's common stock. Shares of common stock are offered pursuant to the Company's shelf registration statement filed within the SEC. During the three ended March 31, 2018, the company sold no shares of common stock under the program. As of March 31, 2018, approximately $16.53 million of common stock remained available for issuance under the At The Market program.

Agreement and Plan of Merger

On December 11, 2017, the Company and Project Hawks Merger Sub LLC (formerly known as Project Hawks Merger Sub Corp.), a newly formed Delaware limited liability company and wholly-owned subsidiary of the Company (“Merger Sub”), entered into an Agreement and Plan of Merger (as amended as of January 18, 2018, the “Merger Agreement") with First BancTrust Corporation, a Delaware corporation (“First Bank”), pursuant to which, among other things, the Company agreed to acquire 100% of the issued and outstanding shares of First Bank pursuant to a business combination whereby First Bank will merge with and into Merger Sub, with Merger Sub as the surviving entity 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 $0.01 per share, of First Bank issued and outstanding immediately prior to the effective time of the Merger (other than shares held in treasury by First Bank and shares held by stockholders who have properly made and not withdrawn a demand for appraisal rights under Delaware law) converted into and become the right to receive, (a) $5.00 in cash and (b) 0.800 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

6

to be withheld and subject to certain adjustments, all as set forth in the Merger Agreement. As of March 31, 2018, First Bank had total consolidated assets of $479.2 million, loans of $369.6 million and total deposits of $391.6 million.

Subsequently, the Merger closed on May 1, 2018. The Company issued an aggregate total of 1,643,900 shares of common stock at $37.32 per share and approximately $10,275,000, including cash in lieu of fractional shares. The accounting for the Merger is incomplete as the Company is still determining the fair value of assets acquired and liabilities assumed.

It is anticipated that First Bank’s wholly-owned bank subsidiary, First Bank & Trust, IL (“First Bank & Trust”), will be merged with and into the Company’s wholly owned bank subsidiary First Mid Bank later in 2018. At the time of the bank merger, First Bank & Trust’s banking offices will become branches of First Mid Bank.

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.

Stock Plans

At the Annual Meeting of Stockholders held April 26, 2017, the stockholders approved the First Mid-Illinois Bancshares, Inc. 2017 Stock Incentive Plan (“SI Plan”).  The SI Plan was implemented to succeed the Company’s 2007 Stock Incentive Plan, which had a ten-year term. The SI Plan is intended to provide a means whereby directors, employees, consultants and advisors of the Company and its subsidiaries may sustain a sense of proprietorship and personal involvement in the continued development and financial success of the Company and its subsidiaries, thereby advancing the interests of the Company and its stockholders.  Accordingly, directors and selected employees, consultants and advisors may be provided the opportunity to acquire shares of common stock of the Company on the terms and conditions established in the SI Plan.

A maximum of 149,983 shares of common stock may be issued under the SI Plan. There have been no stock options awarded under any Company plan since 2008. The Company has awarded 13,250 shares of restricted stock during 2018 and 15,250 and 18,391 restricted stock units during 2018 and 2017, respectively.

Employee Stock Purchase Plan

At the Annual Meeting of Stockholders held April 25, 2018, the stockholders approved the First Mid-Illinois Bancshares, Inc. Employee Stock Purchase Plan (“ESPP”).  The ESPP is intended to promote the interests of the Company by providing eligible employees with the opportunity to purchase shares of common stock of the Company at a 5% discount through payroll deductions. The ESPP is also intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code.  A maximum of 600,000 shares of common stock may be issued under the ESPP.  

Revenue Recognition

Accounting Standards Codification 606, Revenue from Contracts with Customers (“ASC 606”), establishes a revenue recognition model for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. Most of the Company’s revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans and investment securities, and revenue related to mortgage servicing activities, which are subject to other accounting standards. A description of the revenue-generating activities that are within the scope of ASC 606, and included in other income in the Company’s condensed consolidated statements of income are as follows:

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.

7

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 Group (“FMIG”), receives commissions on premiums of new and renewed business policies. FMIG records commission revenue on direct bill policies as the cash is received. For agency bill policies, FMIG 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.

Accumulated Other Comprehensive Income (Loss)

The components of accumulated other comprehensive income (loss) included in stockholders’ equity as of March 31, 2018 and December 31, 2017 are as follows (in thousands):

	Unrealized Gain (Loss) on Securities			Securities with Other-Than-Temporary Impairment Losses			Total

Adoption of New Accounting Guidance

Accounting Standards Update 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification ("ASU 2017-09"). In May 2017, FASB issued ASU 2017-09. This update provides guidance on determining which changes to the terms and conditions of share-based payment awards require the application of modification accounting under Topic 718. The guidance is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The amendments should be applied on a prospective basis to an award modified on or after adoption date. ASU 2017-09 did not have a significant impact on the Company's consolidated financial statement.

Accounting Standards Update 2017-08, Receivables-Nonrefundable Fees and Other Costs ("ASU 2017-08"). In March 2017, FASB issued ASU 2017-08. This update amends the amortization period for certain purchased callable debt securities held at a premium. The update shortens the premium's amortization period to the earliest call date to more closely align the amortization period of premiums to expectations incorporated in market pricing on the underlying securities. For public companies, the update is effective for annual periods beginning after December 15, 2018, and is to be applied on a modified retrospective basis with a cumulative-effect adjustment directly to retained earnings as of the beginning of the adoption period. Early adoption is permitted, including adoption in an interim period. The Company adopted ASU 2017-08 early and there was not a significant impact on the Company's consolidated financial statements.

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 consolidated financial statements. The current accounting policies and procedures of the Company are not anticipated to change, except for the elimination of the Step 2 analysis.

Accounting Standards Update 2016-08, Revenue from Contracts with Customers (Topic 606) (“ASU 2016-08"). In March 2016, the FASB issued ASU 2016-08 which amended the accounting guidance issued by the FASB in May 2014 that revised the criteria for determining when to recognize revenue from contracts with customers and expanded disclosure requirements. The amendment defers the effective date by one year. This accounting guidance can be implemented using either a retrospective method or a cumulative-effect approach. This new guidance is effective for interim and annual reporting periods beginning after December 15, 2017. The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including trust and asset management fees, deposit related fees,

9

interchange fees, merchant income, and annuity and insurance commissions. Based on this assessment, the Company concluded that ASU 2014-09 did not materially change the method in which the Company currently recognizes revenue for these revenue streams.

Accounting Standards Update 2016-01, Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). In January 2016, FASB issued ASU 2016-01 which amends prior guidance to require an entity to measure its equity investments (except those accounted for under the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. An entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of same issuer. The new guidance simplifies the impairment assessment of equity investments without readily determinable fair values, requires public entities to use the exit price notion when measuring fair value of financial instruments for disclosure purposes, requires an entity to present separately in other comprehensive income the portion of the total change in fair value of a liability resulting from changes in the instrument-specific credit risk when the entity has selected fair value option for financial instruments and requires separate presentation of financial assets and liabilities by measurement category and form of financial asset. The new guidance is effective for reporting periods after January 1, 2018 and did not have a significant impact on the Company's consolidated financial statements other than adoption of the standard resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis.

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 will be 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 will be 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. Early adoption is permitted for all entities. Management continues to evaluate the impact ASU 2016-02 will have 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. 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. Management has formed an internal committee to evaluate implementation steps and assess the impact ASU 2016-13 will have on the Company’s consolidated financial statements. The committee has assigned roles and responsibilities, key tasks to complete, and has established a general timeline for implementation. The Company has 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 meets periodically to discuss the latest developments and ensure progress is being made. The team also keeps current on evolving interpretations and industry practices related to ASU 2016-13. The committee continues to evaluate and validate data resources and different loss methodologies. The committee is still evaluating the impact ASU 2016-13 will have on the Company's consolidated financial statements.

Note 2 -- Earnings Per Share

Basic net income per common share available to common stockholders is calculated as net income less preferred stock dividends divided by the weighted average number of common shares outstanding.  Diluted net income per common share available to common stockholders is computed using the weighted average number of common shares outstanding, increased by the assumed conversion of the Company’s convertible preferred stock and the Company’s stock options, unless anti-dilutive.

The components of basic and diluted net income per common share available to common stockholders for the three-month period ended March 31, 2018 and 2017 were as follows:

	Three months ended March 31,
	2018		2017
Basic Net Income per Common Share
Available to Common Stockholders:
Net income	$	8,390,000	$	6,264,000

At December 31, 2017 , there were eleven available-for sale U.S. Treasury securities and obligations of U.S. government corporations and agencies with a fair value of $47,972,000 and unrealized losses of $1,494,000 in a continuous unrealized loss position for twelve months or more. At March 31, 2018 there were seven held-to-maturity U.S. Treasury securities and obligations of U.S. government corporations and agencies with a fair value of $38,137,000 and unrealized losses of $1,422,000 in a continuous unrealized loss position for twelve months or more. At December 31, 2017 there were seven held-to-maturity U.S. Treasury securities and obligations of U.S. government corporations and agencies with a fair value of $14,540,000 and unrealized losses of $453,000 in a continuous unrealized loss position for twelve months or more.

Obligations of states and political subdivisions.  At March 31, 2018 there were thirty-three obligations of states and political subdivisions with a fair value of $14,901,000 and unrealized losses of $882,000 in a continuous loss position for twelve months or more. At December 31, 2017, there were thirty-nine obligations of states and political subdivisions with a fair value of $9,267,000 and unrealized losses of $256,000 in a continuous unrealized loss position for twelve months or more.

Mortgage-backed Securities: GSE Residential. At March 31, 2018 there were twenty-seven mortgage-backed securities with a fair value of $66,119,000 and unrealized losses of $2,791,000 in a continuous unrealized loss position for twelve months or more. At December 31, 2017, there were twenty-six mortgage-backed securities with a fair value of $22,609,000 and unrealized losses of $518,000 in a continuous unrealized loss position for twelve months or more.

Trust Preferred Securities. At March 31, 2018, there was one trust preferred security with a fair value of $2,522,000 and unrealized loss of $327,000 in a continuous unrealized loss position for twelve months or more. At December 31, 2017, there was one trust preferred security with a fair value of $2,548,000 and unrealized loss of $345,000 in a continuous unrealized loss position for twelve months or more. The unrealized loss was primarily due to the long-term nature of the trust preferred security, a lack of demand or inactive market for the security, the impending change to the regulatory treatment of these securities, and concerns regarding the underlying financial institutions that have issued the trust preferred securities.

The Company recorded no other-than-temporary impairment (OTTI) for these securities during 2018 or 2017.   Because it is not more-likely-than-not that the Company will be required to sell the remaining security before recovery of its new, lower amortized cost basis, which may be maturity, the Company does not consider the remainder of the investment to be other-than-temporarily impaired at March 31, 2018. However, future downgrades or additional deferrals and defaults in this security, could result in additional OTTI and consequently, have a material impact on future earnings.

Following are the details for the currently impaired trust preferred security (in thousands):

	Book Value		Fair Value		Unrealized Gains (Losses)			Other-than- temporary Impairment Recorded To-date
PreTSL XXVIII	$	2,849	$	2,522	$	(327	)	$	(1,111	)

Other securities. At March 31, 2018 and December 31, 2017, there were no other securities in a continuous unrealized loss position for twelve months or more.

The Company does not believe any other individual unrealized loss as of March 31, 2018 represents OTTI. However, given the continued disruption in 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.

Other-than-temporary Impairment. Upon acquisition of a security, the Company determines whether it is within the scope of the accounting guidance for investments in debt and equity securities or whether it must be evaluated for impairment under the accounting guidance for beneficial interests in securitized financial assets.

The Company conducts periodic reviews to evaluate its investment securities to determine whether OTTI has occurred. While all securities are considered, the securities primarily impacted by OTTI evaluation are pooled trust preferred securities. For the pooled trust preferred security currently in the investment portfolio, an extensive review is conducted to determine if any additional OTTI has occurred. The Company utilizes an independent third-party to perform the OTTI evaluation. The Company's management reviews the assumption inputs and methodology with the third-party to obtain an understanding of them and determine if they are appropriate for the evaluation. Economic models are used to project future cash flows for the security based on current assumptions for discount rate, prepayments, default and deferral rates and recoveries. These assumptions are determined based on the structure of the issuance, the specific collateral underlying the security, historical performance of trust preferred securities and general state of the economy. The OTTI test compares the present value of the cash flows from quarter to quarter to determine if there has been an adverse change which could indicate additional OTTI.

15

The discount rate assumption used in the cash flow model is equal to the current yield used to accrete the beneficial interest. The Company’s current trust preferred security investment has a floating rate coupon of 3-month LIBOR plus 90 basis points. Since the estimate of 3-month LIBOR is based on the forward curve on the measurement date, and is therefore variable, the discount assumption for this security is a range of projected coupons over the expected life of the security.

The Company considers the likelihood that issuers will prepay their securities which changes the amount of expected cash flows. Factors such as the coupon rates of collateral, economic conditions and regulatory changes, such as the Dodd-Frank Act and Basel III, are considered.

The trust preferred security includes collateral issued by financial institutions and insurance companies. To identify bank issuers with a high risk of near term default or deferral, a credit model developed by the third-party is utilized that scores each bank issuer based on 29 different ratios covering capital adequacy, asset quality, earnings, liquidity, the Texas Ratio, and sensitivity to interest rates. To account for longer term bank default risk not captured by the credit model, it is assumed that banks will default at a rate of 2% annually for the first two years of the cash flow projection, and 36 basis points in each year thereafter. To project defaults for insurance issuers, each issuer’s credit rating is mapped to its idealized default rate, which is AM Best’s estimate of the historical default rate for insurance companies with that rating.

Lastly, it is assumed that trust preferred securities issued by banks that have already failed will have no recoveries, and that banks projected to default will have recoveries of 10%. Additionally, the 10% recovery assumption, incorporates the potential for cures by banks that are currently in deferral.

If the Company determines that a given pooled trust preferred security position will be subject to a write-down or loss, the Company records the expected credit loss as a charge to earnings.

Credit Losses Recognized on Investments. As described above, the Company’s investment in trust preferred security has experienced fair value deterioration due to credit losses but is not otherwise other-than-temporarily impaired. The following table provides information about the trust preferred security for which only a credit loss was recognized in income and other losses are recorded in other comprehensive income (loss) for the three months ended March 31, 2018 and 2017 (in thousands).

Note 4 – Loans and Allowance for Loan Losses

Loans are stated at the principal amount outstanding net of unearned discounts, unearned income and allowance for loan 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. A summary of loans at March 31, 2018 and December 31, 2017 follows (in thousands):

	March 31, 2018		December 31, 2017

Allowance for loan losses	20,771		19,977
Net loans	$	1,955,617	$	1,918,499

Net loans increased$37.1 million as of March 31, 2018 compared to December 31, 2017. The increase was primarily due to increases in commercial real estate loans, commercial and industrial loans, and all other loans offset by seasonal declines in agricultural loans. 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 market value, taking into consideration future commitments to sell the loans. These loans are primarily for 1-4 family residential properties. 

Most of the Company’s business activities are with customers located near the Company's branch locations in Illinois and Missouri.  At March 31, 2018, the Company’s loan portfolio included $196.9 million of loans to borrowers whose businesses are directly related to agriculture. Of this amount, $158.3 million was concentrated in other grain farming. Total loans to borrowers whose businesses are directly related to agriculture decreased$16.9 million from $213.8 million at December 31, 2017 due to seasonal paydowns based upon timing of cash flow requirements. Loans concentrated in other grain farming decreased$12.5 million from $170.8 million at December 31, 2017.  While the Company adheres to sound underwriting practices, including 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 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 $118.4 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 $187.4 million of loans to lessors of non-residential buildings, $131.3 million of loans to lessors of residential buildings and dwellings, and $97.8 million of loans to other gambling industries.

17

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 the vast majority of 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. 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.

18

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.

Purchase Credit-Impaired Loans. Loans acquired with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit impaired. Evidence of credit quality deterioration as of the purchase date may include information such as past-due and nonaccrual status, borrower credit scores and recent loan to value percentages. Purchase credit-impaired ("PCI") loans are accounted for under ASC 310-30, Receivables--Loans and Debt Securities Acquired with Deteriorated Credit Quality ("ASC 310-30"), and are initially measured at fair value, which includes 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 is 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.

Allowance for Loan Losses

The allowance for loan losses represents the Company’s best estimate of the reserve necessary to adequately account for probable losses existing in the current portfolio. The provision for loan losses is the charge against current earnings that is determined by the Company as the amount needed to maintain an adequate allowance for loan losses. In determining the adequacy of the allowance for loan 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 loan losses by separately evaluating large impaired loans and nonimpaired loans.

The Company has loans acquired from business combinations with uncollected principal balances.  These loans are carried net of a fair value adjustment for credit risk and interest rates and are only included in the allowance calculation to the extent that the reserve requirement exceeds the fair value adjustment.  However, as the acquired loans renew, it is necessary to establish an allowance which represents an amount that, in management’s opinion, will be adequate to absorb probable credit losses inherent in such 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, 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 effective interest rate; (2) the loan’s observable market price, if available; or (3) the fair value of the collateral less costs to sell for collateral dependent loans and loans for which foreclosure is deemed to be probable. A specific allowance is assigned when expected cash flows or collateral do not justify the carrying amount of the loan. The carrying value of the loan reflects reductions from prior charge-offs.

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

19

with the individual borrowers. Criticized loans are those assigned risk ratings of Special Mention, Substandard, or Doubtful. Determining the appropriate level of the allowance for loan losses for all non-impaired loans is based on a migration analysis of net losses over a rolling twelve quarter period by loan segment. A weighted average of the net losses is 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. Environmental factors including 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 are evaluated each quarter to determine if adjustments to the weighted average historical net losses is appropriate given these current influences on the risk profile of each loan segment. 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 periodically assessed and adjusted when appropriate. Consumer loans are evaluated for adverse classification based primarily on the Uniform Retail Credit Classification and Account Management Policy established by the federal banking regulators. Classification standards are generally based on delinquency status, collateral coverage, bankruptcy and the presence of fraud.

Due to weakened economic conditions during prior 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 has not materially changed any aspect of its overall approach in the determination of the allowance for loan losses.  However, on an on-going basis the Company continues to refine the methods used in determining management’s best estimate of the allowance for loan losses.

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 all loan portfolio segments except 1-4 family residential properties and consumer, the Company promptly charges-off loans, or portions thereof, when available information confirms that specific loans are uncollectible based on information that includes, but is not limited to, (1) the deteriorating financial condition of the borrower, (2) declining collateral values, and/or (3) legal action, including bankruptcy, that impairs the borrower’s ability to adequately meet its obligations. For impaired loans that are considered to be solely collateral dependent, a partial charge-off is recorded when a loss has been confirmed by an updated appraisal or other appropriate valuation of the collateral.

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.

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, 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.

Impaired Loans

Within all loan portfolio segments, loans are 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

24

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

For the three months ended March 31, 2018 and 2017, the amount of interest income recognized using a cash-basis method of accounting during the period that the loans were impaired was not material.

Non Accrual Loans

The following table presents the Company’s recorded balance of nonaccrual loans as March 31, 2018 and December 31, 2017 (in thousands). This table excludes purchased impaired loans and performing troubled debt restructurings.

Purchased Credit-Impaired Loans

The Company acquired certain loans considered to be credit-impaired ("PCI") in its business combination with First Clover Leaf during the third quarter of 2016. At acquisition, these loans evidenced deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. The carrying amount of these loans is included in the consolidated balance sheet amounts for Loans. The Company had no PCI loans prior to the First Clover Leaf acquisition. The amount of these loans at March 31, 2018 and December 31, 2017 are as follows (in thousands):

	March 31, 2018		December 31, 2017
Commercial real estate	249		251
Commercial and industrial loans	4		8
Carrying amount	253		259
Allowance for loan losses	5		9
Carrying amount, net of allowance	$	248	$	250

As of September 8, 2016, the acquisition date, the principal outstanding of PCI loans totaled $10,650,000 and the fair value of PCI loans totaled $8,688,000. For PCI loans, the difference between contractually required payments at acquisition and the cash flow expected to be collected is referred to as the non-accretable difference. Any excess of expected cash flows over the fair value is referred to as the accretable yield. As of March 31, 2018 there is no accretable yield on the PCI loans acquired. Subsequent decreases to the expected cash flows will result in a provision for loan and lease losses. Subsequent increases in expected cash flows will result in a reversal of the provision for loan and lease losses to the extent of prior charges and then an adjustment to accretable yield, which would have a positive impact on interest income. As of March 31, 2018, there was one loan with a change in expected cash flows and as a result, approximately $5,000 of provision was recorded. As of December 31, 2017, there was one loan with a change in expected cash flows and as a result, approximately $9,000 of provision was recorded.

Troubled Debt Restructuring

The balance of troubled debt restructurings ("TDRs") at March 31, 2018 and December 31, 2017 was $8.2 million and $8.9 million, respectively.  There was $32,000 and $37,000 in specific reserves established with respect to these loans as of March 31, 2018 and December 31, 2017, respectively. As troubled debt restructurings, these loans are included in nonperforming loans and are classified as impaired which requires that they be individually measured for impairment. The modification of the terms of these loans included one or a combination of the following: a reduction of stated interest rate of the loan; an extension of the maturity date and change in payment terms; or a permanent reduction of the recorded investment in the loan. The following table presents the Company’s recorded balance of troubled debt restructurings at March 31, 2018 and December 31, 2017 (in thousands).

Troubled debt restructurings:	March 31, 2018		December 31, 2017
1-4 Family residential properties	943		874
Commercial real estate	1,362		1,376
Loans secured by real estate	2,305		2,250
Agricultural loans	734		757
Commercial and industrial loans	5,029		5,690
Consumer loans	170		201
Total	$	8,238	$	8,898

Commercial real estate	249		251
Loans secured by real estate	979		829
Commercial and industrial loans	20		25
Total	$	999	$	854

27

The decrease in TDRs during the period was was primarily due to loans that paid off. The following table presents loans modified as TDRs during the three months endedMarch 31, 2018 and 2017, as a result of various modified loan factors (in thousands):

	March 31, 2018				March 31, 2017
	Number of Modifications	Recorded Investment		Type of Modifications	Number of Modifications	Recorded Investment		Type of Modifications
1-4 Family residential properties	1	161		(b)	—	—
Total	1	$	161		—	$	—

Type of modifications:

(a) Reduction of stated interest rate of loan

(b) Change in payment terms

(c) Extension of maturity date

(d) Permanent reduction of the recorded investment

A loan is considered to be in payment default once it is 90 days past due under the modified terms.  There were no loans modified as troubled debt restructurings during the prior twelve months that experienced defaults for three months ended March 31, 2018. There was one loan modified as troubled debt restructuring during the prior twelve months that experienced defaults as of December 31, 2017.

The balance of real estate owned includes $1,951,000 and $2,754,000 of foreclosed real estate properties recorded as a result of obtaining physical possession of the property at March 31, 2018 and December 31, 2017, respectively. The recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceeds are in process was $938,000 and $404,000 at March 31, 2018 and December 31, 2017, respectively.

Note 5 -- Goodwill and Intangible Assets

For year ended 12/31/23	1,098

In accordance with the provisions of SFAS No. 142, “Goodwill and Other Intangible Assets,” codified within ASC 350, the Company performed testing of goodwill for impairment as of September 30, 2017 and determined that, as of that date, goodwill was not impaired. Management also concluded that the remaining amounts and amortization periods were appropriate for all intangible assets.

Note 6 -- Repurchase Agreements and Other Borrowings

Securities sold under agreements to repurchase were $132.4 million at March 31, 2018, a decrease of $23.0 million from $155.4 million at December 31, 2017. The decrease during the first three months of 2018 was primarily due to decreases in balances of customers due to changes in cash flow needs for their businesses. All of the transactions have overnight maturities with a weighted average rate of 0.14%.

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.

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.

30

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 and include subordinated tranches of collateralized mortgage obligations and investments in trust preferred securities.

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.

The trust preferred securities are collateralized debt obligation securities that are backed by trust preferred securities issued by banks, thrifts, and insurance companies. The market for these securities at March 31, 2018 is not active and markets for similar securities are also not active. The inactivity was evidenced first by a significant widening of the bid-ask spread in the brokered markets in which trust preferred securities trade and then by a significant decrease in the volume of trades relative to historical levels. The new issue market is also inactive and will continue to be, as a result of the Dodd-Frank Act’s elimination of trust preferred securities from Tier 1 capital for certain holding companies. There are currently very few market participants who are willing and or able to transact for these securities. The market values for these securities are very depressed relative to historical levels. Given conditions in the debt markets today and the absence of observable transactions in the secondary and new issue markets, we determined:

• The few observable transactions and market quotations that are available are not reliable for purposes of determining fair value at March 31, 2018,

• An income valuation approach technique (present value technique) that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs will be equally or more representative of fair value than the market approach valuation technique used at prior measurement dates, and

• The trust preferred securities held by the Company will be classified within Level 3 of the fair value hierarchy because we determined that significant adjustments are required to determine fair value at the measurement date.

31

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 March 31, 2018 and December 31, 2017 (in thousands):

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 March 31, 2018 was $3,996,000 and a fair value of $3,489,000 resulting in specific loss exposures of $507,000.

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 March 31, 2018 was $1,951,000. Other real estate owned included in the total carrying amount and measured at fair value on a nonrecurring basis during the period amounted to $24,000.

The following table presents the fair value measurement of assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at March 31, 2018 and December 31, 2017 (in thousands):

	Fair Value Measurements Using

Sensitivity of Significant Unobservable Inputs

The following is a discussion of the sensitivity of significant unobservable inputs, the interrelationships between those inputs and other unobservable inputs used in recurring fair value measurement and of how those inputs might magnify or mitigate the effect of changes in the unobservable inputs on the fair value measurement.

Trust Preferred Securities. The significant unobservable inputs used in the fair value measurement of the Company’s trust preferred securities are offered quotes and comparability adjustments.  Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement.  Generally, changes in either of those inputs will not affect the other input.

The following table presents quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements other than goodwill at June 30, 2017 and December 31, 2016 (in thousands).

March 31, 2018	Fair Value		Valuation Technique	Unobservable Inputs	Range (Weighted Average)
Trust Preferred Securities	$	2,522	Discounted cash flow	Discount rate	11.7%
				Constant prepayment rate (1)	1.5%
				Cumulative projected prepayments	23.9%
				Probability of default	0.5%
				Projected cures given deferral	0.0%
				Loss severity	97.8%
Impaired loans (collateral dependent)	$	3,489	Third party valuations	Discount to reflect realizable value	0	%	-	40%	(	20%	)
Foreclosed assets held for sale	$	24	Third party valuations	Discount to reflect realizable value less estimated selling costs	0	%	-	40%	(	35%	)

(1) Every five years

Other. The following methods were used to estimate the fair value of all other financial instruments recognized in the accompanying balance sheets at amounts other than fair value.

Cash and Cash Equivalents, Federal Funds Sold, Interest Receivable and Federal Reserve and Federal Home Loan Bank Stock. The carrying amount approximates fair value.

Certificates of Deposit Investments. The fair value of certificates of deposit investments is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities.

Held-to-Maturity Securities. Fair Value is based on quoted market prices, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities.

34

Loans Held for Sale. Loans expected to be sold are classified as held for sale and are recorded at the lower of aggregate cost or market value.

Loans. For March 31, 2018, fair value of loans is estimated on an exit price basis incorporating discounts for credit, liquidity and marketability factors. This is not comparable with the fair values disclosed for December 31, 2017, which were based on an entrance price basis. For that date, fair values of variable rate loans that reprice frequently and with no significant change in credit risk were based on carrying values. The fair values of other loans as of that date were estimated using discounted cash flow analyses which used interest rates then being offered for loans with similar terms to borrowers of similar credit quality. The carrying amount of accrued interest approximates its fair value.

Deposits. Deposits include demand deposits, savings accounts, NOW accounts and certain money market deposits. The carrying amount of these deposits approximates fair value. The fair value of fixed-maturity time deposits is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities.

Securities Sold Under Agreements to Repurchase. The fair value of securities sold under agreements to repurchased is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities.

Interest Payable. The carrying amount approximates fair value.

Junior Subordinated Debentures, Federal Home Loan Bank Borrowings and Other Borrowings. Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt.

The following tables present estimated fair values of the Company’s financial instruments at March 31, 2018 and December 31, 2017 in accordance with FAS 107-1 and APB 28-1, codified with ASC 805 (in thousands):

Acquisition

On December 11, 2017, the Company and Merger Sub entered into the Merger Agreement with First Bank pursuant to which, among other things, the Company agreed to acquire 100% of the issued and outstanding shares of First Bank pursuant to a business combination whereby First Bank will merge with and into Merger Sub, with Merger Sub as the surviving entity and a wholly-owned subsidiary of the Company.

Subsequently, on May 1, 2018, the acquisition was completed.

Overview

This overview of management’s discussion and analysis highlights selected information in this document and may not contain all of the information that is important to you. For a more complete understanding of trends, events, commitments, uncertainties, liquidity, capital resources, and critical accounting estimates which have an impact on the Company’s financial condition and results of operations you should carefully read this entire document.

Net income was $8,390,000 and $6,264,000 for the three months ended March 31, 2018 and 2017, respectively. Diluted net income per common share available to common stockholders was $0.66 and $0.50 for the three months ended March 31, 2018 and 2017.

37

The following table shows the Company’s annualized performance ratios for the three months ended March 31, 2018 and 2017, compared to the performance ratios for the year ended December 31, 2017:

	Three months ended				Year ended
	March 31, 2018		March 31, 2017		December 31, 2017
Return on average assets	1.18	%	0.88	%	0.94	%
Return on average common equity	10.86	%	8.77	%	8.92	%
Average equity to average assets	10.91	%	10.01	%	10.59	%

Total assets were $2.837 billion at March 31, 2018, compared to $2.842 billion as of December 31, 2017. From December 31, 2017 to March 31, 2018, cash and interest bearing deposits decreased$34.0 million, net loan balances increased$37.1 million and investment securities decreased$8.7 million. Net loan balances were $1.96 billion at March 31, 2018 compared to $1.92 billion at December 31, 2017.

Net interest margin, defined as net interest income divided by average interest-earning assets, was 3.57% for the three months ended March 31, 2018, up from 3.50% for the same period in 2017. This increase was primarily due an increase in loan balances and higher yields on investments. Net interest income before the provision for loan losses was $23.2 million compared to net interest income of $22.8 million for the same period in 2017.

Total non-interest income of $7,487,000decreased$9,000 or 0.1% from $7,496,000 for the same period last year. The decline was a result of insurance commissions that were $138,000 lower than last year primarily due to a decrease in contingency income, a decrease in deposit transaction service charges of $77,000 and a decline in other income of $120,000 primarily due to a decrease in loan late charges and closing fees. These declines were offset by increases in trust revenues $147,000, primarily due to an increase in revenue from defined contribution and other retirement accounts, and brokerage revenue of $160,000, primarily due to an increase in the number of brokerage accounts.

Total non-interest expense of $18.4 milliondecreased$828,000 or 4.3% from $19.2 million for the same period last year. This decrease was primarily due to costs of approximately $1.7 million associated with the merger of First Clover Leaf Bank into First Mid Bank during the first quarter of 2017 offset by increases in costs during 2018 for salaries and benefits, occupancy and equipment, and legal fees.

Following is a summary of the factors that contributed to the changes in net income (in thousands):

	Change in Net Income 2018 versus 2017
	Three months ended March 31,
Net interest income	$	423
Provision for loan losses	667
Other income, including securities transactions	(9		)
Other expenses	828
Income taxes	217
Increase in net income	$	2,126

Credit quality is an area of importance to the Company. Total nonperforming loans were $17.9 million at March 31, 2018, compared to $27.7 million at March 31, 2017 and $17.5 million at December 31, 2017. See the discussion under the heading “Loan Quality and Allowance for Loan Losses” for a detailed explanation of these balances. Repossessed asset balances totaled $2.0 million at March 31, 2018 compared to $2.4 million at March 31, 2017 and $2.8 million at December 31, 2017. The Company’s provision for loan losses for the three months ended March 31, 2018 and 2017 was $1,055,000 and $1,722,000, respectively.  Total loans past due 30 days or more were 0.75% of loans at March 31, 2018 compared to 0.62% at March 31, 2017, and 0.56% of loans at December 31, 2017.  At March 31, 2018, the composition of the loan portfolio remained similar to the same period last year. Loans secured by both commercial and residential real estate comprised approximately 64.7% of the loan portfolio as of March 31, 2018 and 65.6% as of December 31, 2017.

The Company’s capital position remains strong and the Company has consistently maintained regulatory capital ratios above the “well-capitalized” standards. The Company’s Tier 1 capital to risk weighted assets ratio calculated under the regulatory risk-based capital requirements at March 31, 2018 and 2017 and December 31, 2017 was 12.17%, 12.07% and 11.83%, respectively. The Company’s total capital to risk weighted assets ratio calculated under the regulatory risk-based capital requirements at March 31, 2018 and 2017 and December 31, 2017 was 13.07%, 12.89% and 12.70%, respectively. The increase in these ratios from December 31, 2017 was primarily due to net income added to retained earnings.

The Company’s liquidity position remains sufficient to fund operations and meet the requirements of borrowers, depositors, and creditors. The Company maintains various sources of liquidity to fund its cash needs. See the discussion under the heading “Liquidity” for a full listing of sources and anticipated significant contractual obligations.

The Company 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.  The total outstanding commitments at March 31, 2018 and 2017 were $407 million and $471 million, respectively.  

Federal Deposit Insurance Corporation Insurance Coverage. As an FDIC-insured institution, First Mid Bank is required to pay deposit insurance premium assessments to the FDIC.  A number of requirements with respect to the FDIC insurance system have affect results, including insurance assessment rates. The Company expensed $253,000 and $152,000 for this assessment during the first three months of 2018 and 2017, respectively.

In addition to its insurance assessment, each insured bank is subject to quarterly debt service assessments in connection with bonds issued by a government corporation that financed the federal savings and loan bailout.  The Company expensed $28,000 and $27,000 during the first three months of 2018 and 2017 for this assessment, respectively.

Basel III. In September 2010, the Basel Committee on Banking Supervision proposed higher global minimum capital standards, including a minimum Tier 1 common capital ratio and additional capital and liquidity requirements. On July 2, 2013, the Federal Reserve Board approved a final rule to implement these reforms and changes required by the Dodd-Frank Act. This final rule was subsequently adopted by the OCC and the FDIC.

As included in the proposed rule of June 2012, the final rule includes new risk-based capital and leverage ratios, which will be phased in from 2015 to 2019, and refines the definition of what constitutes “capital” for purposes of calculating those ratios. The new minimum capital level requirements applicable to the Company and First Mid Bank beginning in 2015 are: (i) a new common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6%; (iii) a total capital ratio of 8%; and (iv) a Tier 1 leverage ratio of 4%. The rule also establishes a “capital conservation buffer” of 2.5% above the new regulatory minimum capital requirements, which must consist entirely of common equity Tier 1 capital and would result in the following minimum ratios: (i) a common equity Tier 1 capital ratio of 7.0%, (ii) a Tier 1 capital ratio of 8.5%, and (iii) a total capital ratio of 10.5%. The new capital conservation buffer requirement is being phased in beginning in January 2016 at 0.625% of risk weighted assets and will increase by that amount each year until fully implemented in January 2019. An institution will be subject to limitations on paying dividends, engaging in share repurchases and paying discretionary bonuses if its capital level falls below the buffer amount.

The final rule also makes three changes to the proposed rule of June 2012 that impact the Company. First, the proposed rule would have required banking organizations to include accumulated other comprehensive income (“AOCI”) in common equity tier 1 capital. AOCI includes accumulated unrealized gains and losses on certain assets and liabilities that have not

39

been included in net income. Under existing general risk-based capital rules, most components of AOCI are not included in a banking organization's regulatory capital calculations. The final rule allows community banking organizations to make a one-time election not to include these additional components of AOCI in regulatory capital and instead use the existing treatment under the general risk-based capital rules that excludes most AOCI components from regulatory capital.

Second, the proposed rule would have modified the risk-weight framework applicable to residential mortgage exposures to require banking organizations to divide residential mortgage exposure into two categories in order to determine the applicable risk weight. The final rule, however, retains the existing treatment for residential mortgage exposures under the general risk-based capital rules.

Third, the proposed rule would have required banking organizations with total consolidated assets of less than $15 billion as of December 31, 2009, such as the Company, to phase out over ten years any trust preferred securities and cumulative perpetual preferred securities from its Tier 1 capital regulatory capital. The final rule, however, permanently grandfathers into Tier 1 capital of depository institution holding companies with total consolidated assets of less than $15 billion as of December 31, 2009 any trust preferred securities or cumulative perpetual preferred stock issued before May 19, 2010.

See discussion under the heading "Capital Resources" for a description of the Company's and First Mid Bank's risk-based capital.

Critical Accounting Policies and Use of Significant Estimates

The Company has established various accounting policies that govern the application of U.S. generally accepted accounting principles in the preparation of the Company’s financial statements. The significant accounting policies of the Company are described in the footnotes to the consolidated financial statements included in the Company’s 2017 Annual Report on Form 10-K. Certain accounting policies involve significant judgments and assumptions by management that have a material impact on the carrying value of certain assets and liabilities; management considers such accounting policies to be critical accounting policies. The judgments and assumptions used by management are based on historical experience and other factors, which are believed to be reasonable under the circumstances. Because of the nature of the judgments and assumptions made by management, actual results could differ from these judgments and assumptions, which could have a material impact on the carrying values of assets and liabilities and the results of operations of the Company.

Allowance for Loan Losses. The Company believes the allowance for loan losses is the critical accounting policy that requires the most significant judgments and assumptions used in the preparation of its consolidated financial statements. An estimate of potential losses inherent in the loan portfolio are determined and an allowance for those losses is established by considering factors including historical loss rates, expected cash flows and estimated collateral values. In assessing these factors, the Company use organizational history and experience with credit decisions and related outcomes. The allowance for loan losses represents the best estimate of losses inherent in the existing loan portfolio. The allowance for loan losses is increased by the provision for loan losses charged to expense and reduced by loans charged off, net of recoveries. The Company formally evaluates the allowance for loan losses quarterly. If the underlying assumptions later prove to be inaccurate based on subsequent loss evaluations, the allowance for loan losses is adjusted.

The Company estimates the appropriate level of allowance for loan losses by separately evaluating impaired and non-impaired 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 non-impaired loan is more subjective. Generally, the allowance assigned to non-impaired loans is determined based on migration analysis of historical net losses on each loan segment 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 loan losses would be required.

40

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 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 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.

Investment in Debt and Equity Securities. The Company classifies its investments in debt and equity securities as either held-to-maturity or available-for-sale in accordance with Statement of Financial Accounting  Standards (SFAS) No. 115, “Accounting for Certain Investments in Debt and Equity Securities,” which was codified into 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 amounts, thereby affecting the financial position, results of operations and cash flows of the Company. If the estimated value of investments is less than the cost or amortized cost, the Company evaluates whether an event or change in circumstances has occurred that may have a significant adverse effect on the fair value of the investment. If such an event or change has occurred and the Company determines that the impairment is other-than-temporary, a further determination is made as to the portion of impairment that is related to credit loss. The impairment of the investment that is related to the credit loss is expensed in the period in which the event or change occurred. The remainder of the impairment is recorded in other comprehensive income.

Deferred Income Tax Assets/Liabilities. The Company’s net deferred income tax asset arises from differences in the dates that items of income and expense enter into our reported income and taxable income. Deferred tax assets and liabilities are established for these items as they arise. From an accounting standpoint, deferred tax assets are reviewed to determine if they are realizable based on the historical level of taxable income, estimates of future taxable income and the reversals of deferred tax liabilities. In most cases, the realization of the deferred tax asset is based on future profitability. If the Company were to experience net operating losses for tax purposes in a future period, the realization of deferred tax assets would be evaluated for a potential valuation reserve.

Additionally, the Company reviews its uncertain tax positions annually under FASB Interpretation No. 48 (FIN No. 48), “Accounting for Uncertainty in Income Taxes,” codified within ASC 740. An uncertain tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount actually recognized is the largest amount of tax benefit that is greater than 50% likely to be recognized on examination. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded. A significant amount of judgment is applied to determine both whether the tax position meets the "more likely than not" test as well as to determine the largest amount of tax benefit that is greater than 50% likely to be recognized. Differences between the position taken by management and that of taxing authorities could result in a reduction of a tax benefit or increase to tax liability, which could adversely affect future income tax expense.

Impairment of Goodwill and Intangible Assets. Core deposit and customer relationships, which are intangible assets with a finite life, are recorded on the Company’s balance sheets. These intangible assets were capitalized as a result of past acquisitions and are being amortized over their estimated useful lives of up to 15 years. Core deposit intangible assets, with finite lives will be tested for impairment when changes in events or circumstances indicate that its carrying amount may not be recoverable. Core deposit intangible assets were tested for impairment as of September 30, 2017 as part of the goodwill impairment test and no impairment was identified.

As a result of the Company’s acquisition activity, goodwill, an intangible asset with an indefinite life, is reflected on the consolidated balance sheets. Goodwill is evaluated for impairment annually, unless there are factors present that indicate a potential impairment, in which case, the goodwill impairment test is performed more frequently than annually.

41

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.

SFAS No. 157, “Fair Value Measurements”, which was codified into ASC 820, establishes a framework for measuring the fair value of financial instruments that considers the attributes specific to particular assets or liabilities and establishes a three-level hierarchy for determining fair value based on the transparency of inputs to each valuation as of the fair value measurement date.

The three levels are defined as follows:

• Level 1 — quoted prices (unadjusted) for identical assets or liabilities in active markets.

• Level 2 — inputs include quoted prices for similar assets and liabilities in active markets, quoted prices of identical or similar assets or liabilities in markets that are not active, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

• Level 3 — inputs that are unobservable and significant to the fair value measurement.

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 7 – Fair Value of Assets and Liabilities.

Results of Operations

Net Interest Income

The largest source of revenue for the Company is net interest income. Net interest income represents the difference between total interest income earned on earning assets and total interest expense paid on interest-bearing liabilities.  The amount of interest income is dependent upon many factors, including the volume and mix of earning assets, the general level of interest rates and the dynamics of changes in interest rates.  The cost of funds necessary to support earning assets varies with the volume and mix of interest-bearing liabilities and the rates paid to attract and retain such funds.  

42

(1) Changes attributable to the combined impact of volume and rate have been allocated proportionately to the change due to volume and the change due to rate.

(2) The tax-exempt income is not recorded on a tax-equivalent basis.

(3) Nonaccrual loans have been included in the average balances.

Net interest income increased$0.4 million, or 1.9%, to $23.2 million for the three months endedMarch 31, 2018, from $22.8 million for the same period in 2017. Net interest income increased due to higher interest rates offset by higher deposit costs. The net interest margin increased primarily due higher yields on loans and investments.

For the three months endedMarch 31, 2018, average earning assets decreased by $7.5 million, or 0.3%, and average interest-bearing liabilities decreased$66.5 million or 3.2%, compared with average balances for the same period in 2017.

44

The changes in average balances for these periods are shown below:

• Average interest-bearing deposits held by the Company decreased$45.1 million or 76.1%.

• Average federal funds sold decreased$34.6 million or 98.6%.

• Average certificates of deposits investments decreased$6.6 million or 79.7%

• Average loans increased by $151.7 million or 8.4%.

• Average securities decreased by $72.9 million or 10.0%.

• Average deposits decreased by $92.4 million or 4.9%.

• Average securities sold under agreements to repurchase increased by $1.8 million or 1.1%.

• Average borrowings and other debt increased by $24.1 million or 29.8%.

• Net interest margin increased to 3.57% for the first three months of 2018 from 3.50% for the first three months of 2017.

To compare the tax-exempt yields on interest-earning assets to taxable yields, the Company also computes non-GAAP net interest income on a tax equivalent basis (TE) where the interest earned on tax-exempt loans and securities is adjusted to an amount comparable to interest subject to normal income taxes assuming a federal tax rate of 21% (referred to as the tax equivalent adjustment). The year-to-date net yield on interest-earning assets (TE) was 3.65% and 3.63% for the first three months of 2018 and 2017, respectively. The TE adjustments to net interest income for the three months ended March 31, 2018 and 2017 were $465,000 and $848,000, respectively.

Provision for Loan Losses

The provision for loan losses for the three months ended March 31, 2018 and 2017 was $1,055,000 and $1,722,000, respectively.  The decrease in provision expense was primarily due to a decrease in non-performing loans and net charge-offs. Net charge-offs were $261,000 for the three months ended March 31, 2018, compared to net charge offs of $629,000 for March 31, 2017.  Nonperforming loans were $17.9 million and $27.7 million as of March 31, 2018 and 2017, respectively.   For information on loan loss experience and nonperforming loans, see discussion under the “Nonperforming Loans” and “Loan Quality and Allowance for Loan Losses” sections below.

Other Income

An important source of the Company’s revenue is other income.  The following table sets forth the major components of other income for the three-months ended March 31, 2018 and 2017 (in thousands):

	Three months ended March 31,
	2018		2017		$ Change
Trust revenues	$	1,077	$	930	$	147
Brokerage commissions	665		505		160
Insurance commissions	1,487		1,625		(138		)
Service charges	1,635		1,712		(77		)
Security gains, net	20		—		20
Mortgage banking revenue, net	161		193		(32		)
ATM / debit card revenue	1,604		1,568		36
Bank Owned Life Insurance	276		281		(5		)
Other	562		682		(120		)
Total other income	$	7,487	$	7,496	$	(9	)

Following are explanations of the changes in these other income categories for the three months ended March 31, 2018 compared to the same period in 2017:

• Trust revenues increased$147,000 or 15.8% to $1,077,000 from $930,000 primarily from an increase in revenue from defined contribution and other retirement accounts due to increases in the market value of the assets. Trust assets, at market value, were $984.0 million at March 31, 2018 compared to $853.5 million at March 31, 2017.

45

• Revenues from brokerage increased$160,000 or 31.7% to $665,000 from $505,000 primarily due to an increase in the number of brokerage accounts from new business development efforts.

• Insurance commissions decreased$138,000 or 8.5% to $1,487,000 from $1,625,000 primarily due to a decrease in commissions and contingency income received from carriers based on claims experience during 2018 compared to 2017.

• Fees from service charges decreased$77,000 or 4.5% to $1,635,000 from $1,712,000 primarily due to a decrease in service charges based on the number of deposit transactions.

• The sale of securities during the three months ended March 31, 2018 resulted in net securities gains of $20,000 compared to $0 during the three months ended March 31, 2017.

• Mortgage banking income decreased$32,000 or 16.6% to $161,000 from $193,000. Loans sold balances were as follows:

• $11.5 million (representing 86 loans) for the three months ended March 31, 2018

• $13.8 million (representing 103 loans) for the three months ended March 31, 2017

First Mid Bank generally releases the servicing rights on loans sold into the secondary market.

• Revenue from ATMs and debit cards increased$36,000 or 2.3% to $1,604,000 from $1,568,000 due to an increase in electronic transactions.

• Bank owned life insurance income decreased$5,000 or 1.8%.

• Other income decreased$120,000 or 17.6% to $562,000 from $682,000 primarily due to a decline in loan late charges and closing fees resulting from less loan transaction activity.

Other Expense

The major categories of other expense include salaries and employee benefits, occupancy and equipment expenses and other operating expenses associated with day-to-day operations.  The following table sets forth the major components of other expense for the three-months ended March 31, 2018 and 2017 (in thousands):

	Three months ended March 31,
	2018		2017		$ Change
Salaries and employee benefits	$	10,194	$	9,935	$	259
Net occupancy and equipment expense	3,273		3,133		140
Net other real estate owned expense (income)	76		18		58
FDIC insurance	281		179		102
Amortization of intangible assets	505		547		(42		)
Stationery and supplies	211		185		26
Legal and professional	1,137		831		306
Marketing and donations	354		294		60
Other operating expenses	2,343		4,080		(1,737		)
Total other expense	$	18,374	$	19,202	$	(828	)

Following are explanations for the changes in these other expense categories for the three months ended March 31, 2018 compared to the same period in 2017:

• Salaries and employee benefits, the largest component of other expense, increased$259,000 or 2.6% to $10,194,000 from $9,935,000.  The increase is primarily due to merit increases in 2018 for continuing employees during the first quarter of 2018. There were 591 and 590 full-time equivalent employees at March 31, 2018 and 2017, respectively.

46

• Occupancy and equipment expense increased$140,000 or 4.5% to $3,273,000 from $3,133,000. The increase was primarily due to increases maintenance and repair expense, rent expense, and building insurance.

• Net other real estate owned expense increased$58,000 or 322.2% to $76,000 from $18,000. The increase in 2018 was primarily due to losses on properties sold during 2018.

• Expense for amortization of intangible assets decreased$42,000 or 7.7% to $505,000 from $547,000 for the three months endedMarch 31, 2018 and 2017, respectively. The decrease in 2018 was due to less amortization expense for core deposit intangibles in 2018 compared to 2017.

• Other operating expenses decreased$1,737,000 or 42.6% to $2,343,000 in 2018 from $4,080,000 in 2017 primarily due costs associated with the merger of First Clover Leaf Bank into First Mid Bank during the first quarter of 2017.

• On a net basis, all other categories of operating expenses increased$494,000 or 33.2% to $1,983,000 in 2018 from $1,489,000 in 2017.  The increase is primarily due to an increase in legal and professional fees primarily associated with the acquisition of First Bank and an increase in FDIC insurance assessments due to an increase in rates and total assets.

Income Taxes

Total income tax expense amounted to $2.9 million (25.4% effective tax rate) for the three months endedMarch 31, 2018, compared to $3.1 million (33.0% effective tax rate) for the same period in 2017. The decline in effective tax rate for the three months ended March 31, 2018 compared to the same period in 2017 is primarily due to a change in the federal statutory corporate tax rate from 35% to 21% effective January 1, 2018 following the enactment of certain tax reforms through the Tax Cuts and Jobs Act, offset by an increase in State of Illinois tax rate from 7.75% to 9.50% beginning July 1, 2017.

The Company files U.S. federal and state of Illinois income tax returns.  The Company is no longer subject to U.S. federal or state income tax examinations by tax authorities for years before 2015.

The trust preferred pooled security is a Collateralized Debt Obligation (“CDOs”) backed by a pool of debt securities issued by financial institutions. The collateral consists of trust-preferred securities and subordinated debt securities issued by banks, bank holding companies and insurance companies. Performing collateral is the amount of remaining collateral less the balances of collateral in deferral or default. Subordination is the amount of performing collateral in excess of the current balance of a specified class and all classes senior to the specified class.  Excess subordination is the amount that the performing collateral balance exceeds the current outstanding balance of the specific class, plus all senior classes. It is a static measure of credit enhancement, but does not incorporate all of the structural elements of the security deal. This amount can also be impacted by future defaults and deferrals, deferring balances that cure or redemptions of securities by issuers. A negative excess subordination indicates that the current performing collateral of the security would be insufficient to pay the current principal balance of the class notes after all of the senior classes’ notes were paid. However, the performing collateral

49

balance excludes the collateral of issuers currently deferring their interest payments. Because these issuers are expected to resume payment in the future (within five years of the first deferred interest period), a negative excess subordination does not necessarily mean a class note holder will not receive a greater than projected or even full payment of cash flow at maturity.

The Company’s trust preferred security investment allows, under the terms of the issue, for issuers to defer interest for up to five consecutive years. After five years, if not cured, the security is considered to be in default and the trustee may demand payment in full of principal and accrued interest. Issuers are also considered to be in default in the event of the failure of the issuer or a subsidiary. The structuring of the trust preferred security provides for a waterfall approach to absorbing losses whereby lower classes or tranches are initially impacted and more senior tranches are only impacted after lower tranches can no longer absorb losses. Likewise, the waterfall approach also applies to principal and interest payments received, as senior tranches have priority over lower tranches in the receipt of payments. Both deferred and defaulted issuers are considered non-performing, and the trustee calculates, on a quarterly basis, certain coverage tests prior to the payment of cash interest to owners of the various tranches of the securities. The coverage tests are compared to an over-collateralization target that states the balance of performing collateral as a percentage of the tranche balance plus the balance of all senior tranches. The tests must show that performing collateral is sufficient to meet requirements for the senior tranches, both in terms of cash flow and collateral value, before cash interest can be paid to subordinate tranches. As a result of the cash flow waterfall provisions within the structure of the security, when a senior tranche fails its coverage test, all of the cash flows that would have been paid to lower tranches are paid to the senior tranche and recorded as a reduction of the senior tranches’ principal. This principal reduction in the senior tranche continues until the coverage test of the senior tranche is passed or the principal of the tranche is paid in full. For so long as the cash flows are being diverted to the senior tranches, the amount of interest due and payable to the subordinate tranches is capitalized and recorded as an increase in the principal value of the tranche. The Company’s trust preferred security investment is in the mezzanine tranche or class which is subordinate to more senior tranches of the issue.

The impact of payment of PIK to subordinate tranches is to strengthen the position of the senior tranches by reducing the senior tranches’ principal balances relative to available collateral and cash flow.  The impact to the subordinate tranches is to increase principal balances, decrease cash flow, and increase credit risk to the tranches receiving the PIK. The risk to holders of a security of a tranche in PIK status is that the remaining total cash flow will not be sufficient to repay all principal and capitalized interest related to the investment.

During the fourth quarter of 2010, after analysis of the expected future cash flows and the timing of resumed interest payments, the Company determined that placing the trust preferred security on non-accrual status was the most prudent course of action. The Company stopped all accrual of interest and ceased to capitalize any PIK to the principal balance of the security.  The Company intends to keep the security on non-accrual status until the scheduled interest payments resume on a regular basis and any previously recorded PIK has been paid. The PIK status of the securities, among other factors, indicates potential other-than-temporary impairment (“OTTI”) and accordingly, the Company has performed further detailed analysis of the investments cash flows and the credit conditions of the underlying issuers. This analysis incorporates, among other things, the waterfall provisions and any resulting PIK status of these securities to determine if cash flow will be sufficient to pay all principal and interest due to the investment tranche held by the Company.  

See discussion below and Note 3 – Investment Securities in the notes to the financial statements for more detail regarding this analysis. Based on this analysis, the Company believes the amortized costs recorded for the trust preferred security investment accurately reflects the position of the security at March 31, 2018 and December 31, 2017.

Other-than-temporary Impairment of Securities

Declines in the fair value, or unrealized losses, of all available for sale investment securities, are reviewed to determine whether the losses are either a temporary impairment or OTTI. Temporary adjustments are recorded when the fair value of a security fluctuates from its historical cost. Temporary adjustments are recorded in accumulated other comprehensive income, and impact the Company’s equity position. Temporary adjustments do not impact net income. A recovery of available for sale security prices also is recorded as an adjustment to other comprehensive income for securities that are temporarily impaired, and results in a positive impact to the Company’s equity position.

50

OTTI is recorded when the fair value of an available for sale security is less than historical cost, and it is probable that all contractual cash flows will not be collected. Investment securities are evaluated for OTTI on at least a quarterly basis. In conducting this assessment, the Company evaluates a number of factors including, but not limited to:

• how much fair value has declined below amortized cost;

• how long the decline in fair value has existed;

• the financial condition of the issuers;

• contractual or estimated cash flows of the security;

• underlying supporting collateral;

• past events, current conditions and forecasts;

• significant rating agency changes on the issuer; and

• the Company’s intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.

If the Company intends to sell the security or if it is more likely than not the Company will be required to sell the security before recovery of its amortized cost basis, the entire amount of OTTI is recorded to noninterest income, and therefore, results in a negative impact to net income. Because the available for sale securities portfolio is recorded at fair value, the conclusion as to whether an investment decline is other-than-temporarily impaired, does not significantly impact the Company’s equity position, as the amount of the temporary adjustment has already been reflected in accumulated other comprehensive income/loss.

If the Company does not intend to sell the security and it is not more-likely-than-not it will be required to sell the security before recovery of its amortized cost basis, only the amount related to credit loss is recognized in earnings.  In determining the portion of OTTI that is related to credit loss, the Company compares the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. The remaining portion of OTTI, related to other factors, is recognized in other comprehensive earnings, net of applicable taxes.

The term “other-than-temporary” is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value are not necessarily favorable, or that there is a general lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. See Note 3 -- Investment Securities in the Notes to Condensed Consolidated Financial Statements (unaudited) for a discussion of the Company’s evaluation and subsequent charges for OTTI.

Loans

The loan portfolio (net of unearned interest) is the largest category of the Company’s earning assets.  The following table summarizes the composition of the loan portfolio, including loans held for sale, as of March 31, 2018 and December 31, 2017 (in thousands):

	March 31, 2018		% Outstanding Loans		December 31, 2017		% Outstanding Loans
Construction and land development	$	109,076	5.5	%	$	107,594	5.5	%
Agricultural real estate	122,564		6.2	%	127,183		6.6	%
1-4 Family residential properties	289,899		14.7	%	293,667		15.1	%
Multifamily residential properties	60,881		3.1	%	61,798		3.2	%
Commercial real estate	699,142		35.2	%	681,757		35.2	%

Agricultural loans	74,342		3.8	%	86,631		4.5	%
Commercial and industrial loans	458,691		23.2	%	444,263		22.9	%
Consumer loans	28,784		1.5	%	29,749		1.5	%
All other loans	134,318		6.8	%	106,859		5.5	%
Total loans	$	1,977,697	100.0	%	$	1,939,501	100.0	%

51

Overall loan balances increased$38.2 million, or 1.97%.  The balance of real estate loans held for sale, included in the balances shown above, amounted to $1,309,000 and $1,025,000 as of March 31, 2018 and December 31, 2017, respectively.

Commercial and commercial real estate loans generally involve higher credit risks than residential real estate and consumer loans. Because payments on loans secured by commercial real estate or equipment are often dependent upon the successful operation and management of the underlying assets, repayment of such loans may be influenced to a great extent by conditions in the market or the economy. The Company does not have any sub-prime mortgages or credit card loans outstanding which are also generally considered to be higher credit risk.

The following table summarizes the loan portfolio geographically by branch region as of March 31, 2018 and December 31, 2017 (dollars in thousands):

	March 31, 2018				December 31, 2017
	Principal balance		% Outstanding Loans		Principal balance		% Outstanding loans
Central region	558,952		28.3	%	543,938		28.0	%
Sullivan region	162,666		8.2	%	167,977		8.7	%
Decatur region	380,321		19.2	%	378,867		19.5	%
Peoria region	188,584		9.5	%	189,639		9.8	%
Highland region	559,248		28.3	%	525,983		27.1	%
Southern region	127,926		6.5	%	133,097		6.9	%
Total all regions	$	1,977,697	100.0	%	$	1,939,501	100.0	%

Loans are geographically dispersed among these regions located in central and southwestern Illinois. While these regions have experienced some economic stress during 2018 and 2017, the Company does not consider these locations high risk areas since these regions have not experienced the significant declines in real estate values seen in some other areas in the United States.

The Company does not have a concentration, as defined by the regulatory agencies, in construction and land development loans or commercial real estate loans as a percentage of total risk-based capital for the periods shown above. At March 31, 2018 and December 31, 2017, the Company did have industry loan concentrations in excess of 25% of total risk-based capital in the following industries (dollars in thousands):

	March 31, 2018				December 31, 2017
	Principal balance		% Outstanding Loans		Principal balance		% Outstanding Loans
Other grain farming	$	158,333	8.01	%	$	170,758	8.80	%
Lessors of non-residential buildings	187,388		9.48	%	185,967		9.59	%

(1) Based upon remaining contractual maturity.

(2) Includes demand loans, past due loans and overdrafts.

As of March 31, 2018, loans with maturities over one year consisted of approximately $1.3 billion in fixed rate loans and approximately $309 million in variable rate loans.  The loan maturities noted above are based on the contractual provisions of the individual loans.  The Company has no general policy regarding renewals and borrower requests, which are handled on a case-by-case basis.

Nonperforming Loans and Nonperforming Other Assets

Nonperforming loans include: (a) loans accounted for on a nonaccrual basis; (b) accruing loans contractually past due ninety days or more as to interest or principal payments; and (c) loans not included in (a) and (b) above which are defined as “troubled debt restructurings”. Repossessed assets include primarily repossessed real estate and automobiles.

The Company’s policy is to discontinue the accrual of interest income on any loan for which principal or interest is ninety days past due.  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. 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.

Restructured loans are loans on which, due to deterioration in the borrower’s financial condition, the original terms have been modified in favor of the borrower or either principal or interest has been forgiven. Repossessed assets represent property acquired as the result of borrower defaults on loans. These assets are recorded at estimated fair value, less estimated selling costs, at the time of foreclosure or repossession.  Write-downs occurring at foreclosure are charged against the allowance for loan losses. On an ongoing basis, properties are appraised as required by market indications and applicable regulations. Write-downs for subsequent declines in value are recorded in non-interest expense in other real estate owned along with other expenses related to maintaining the properties.

Loan Quality and Allowance for Loan Losses

The allowance for loan losses represents management’s estimate of the reserve necessary to adequately account for probable losses existing in the current portfolio. The provision for loan losses is the charge against current earnings that is determined by management as the amount needed to maintain an adequate allowance for loan losses.  In determining the adequacy of the allowance for loan losses, and therefore the provision to be charged to current earnings, management 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 overall lending policy and is intended to identify, at the earliest possible stage, borrowers who might be facing financial difficulty. Factors considered by management in evaluating the overall adequacy of the allowance include a migration analysis of the historical net loan losses by loan segment, the level and composition of nonaccrual, past due and renegotiated loans, 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.

Management reviews economic factors including 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, 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 reserve. Management considers the allowance for loan losses a critical accounting policy.

Management recognizes there are risk factors that are inherent in the Company’s loan portfolio.  All financial institutions face risk factors in their loan portfolios because risk exposure is a function of the business.  The Company’s operations (and therefore its loans) are concentrated in east central Illinois, an area where agriculture is the dominant industry.  Accordingly, lending and other business relationships with agriculture-based businesses are critical to the Company’s success. At March 31, 2018, the Company’s loan portfolio included $196.9 million of loans to borrowers whose businesses are directly related to agriculture. Of this amount, $158.3 million was concentrated in other grain farming. Total loans to borrowers whose businesses are directly related to agriculture decreased$16.9 million from $213.8 million at December 31, 2017 while loans concentrated in other grain farming decreased$12.5 million from $170.8 million at December 31, 2017.  

While the Company adheres to sound underwriting practices, including 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 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 $118.4 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 $187.4 million of loans to lessors of non-residential buildings, $131.3 million of loans to lessors of residential buildings and dwellings, and $97.8 million of loans to other gambling industries.

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.

55

The Company minimizes credit risk by adhering to sound underwriting and credit review policies.  Management and the board of directors of the Company review these policies at least annually.  Senior management is actively involved in business development efforts and the maintenance and monitoring of credit underwriting and approval.  The loan review system and controls are designed to identify, monitor and address asset quality problems in an accurate and timely manner.  The board of directors and management review the status of problem loans each month and formally determine a best estimate of the allowance for loan losses on a quarterly basis.  In addition to internal policies and controls, regulatory authorities periodically review asset quality and the overall adequacy of the allowance for loan losses.

Analysis of the allowance for loan losses as of March 31, 2018 and 2017, and of changes in the allowance for the three month periods ended March 31, 2018 and 2017, is as follows (dollars in thousands):

	Three months ended March 31,

Ratio of annualized net charge-offs to average loans	0.05		%	0.14		%
Ratio of allowance for loan losses to loans outstanding (less unearned interest at end of period)	1.05		%	0.99		%
Ratio of allowance for loan losses to nonperforming loans	116		%	65		%

The ratio of allowance for loan losses to loans outstanding was 1.05% as of March 31, 2018 compared to 0.99% as of March 31, 2017. The ratio of the allowance for loan losses to nonperforming loans is 116% as of March 31, 2018 compared to 65% as of March 31, 2017.  The increase in this ratio is primarily due to an increase in loan balances and the decrease in nonperforming loans to $17.9 million at March 31, 2018 from $27.7 million at March 31, 2017.

During the first three months of 2018, the Company had net charge-offs of $261,000 compared to net charge-offs of $629,000 in 2017. During the first three months of 2018, there was a significant charge off of two commercial loans to a single borrower of $126,000. During the first three months of 2017, there was one significant charge off of a commercial real estate loan to a single borrower of $122,000, and charge offs of five commercial operating loans to two borrowers of $463,000.

The Company is party to a revolving credit agreement with The Northern Trust Company in the amount of $10 million. The balance on this line of credit was $0 as of March 31, 2018. This loan was renewed on April 13, 2018 for one year as a revolving credit agreement with a maximum available balance of $10 million. The interest rate is floating at 2.25% over the federal funds rate (3.93% at March 31, 2018). The loan is secured by all of the stock of First Mid Bank. The Company and First Mid Bank were in compliance with the then existing covenants at March 31, 2018 and 2017 and December 31, 2017.

On September 7, 2016, the Company entered into a credit agreement with The Northern Trust Company in the amount of $15 million as a fixed-rate note with a maturity date of September 7, 2020. This credit agreement was amended and restated on April 13, 2018. The interest rate is floating at 2.25% over the federal funds rate (3.93% at March 31, 2018) and interest and principal payments are due quarterly. As of March 31, 2018, the balance due was $9.4 million. The loan is secured by all of the stock of First Mid Bank. The Company used the proceeds of this note to fund the cash portion of the acquisition price of First Clover Leaf. The Company and First Mid Bank were in compliance with the then existing covenants at March 31, 2018 and December 31, 2017.

On February 27, 2004, the Company completed the issuance and sale of $10 million of floating rate trust preferred securities through First Mid-Illinois Statutory Trust I (“Trust I”), a statutory business trust and wholly-owned unconsolidated subsidiary of the Company, as part of a pooled offering.  The Company established Trust I 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 I, 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 I mature in 2034, bear interest at three-month London Interbank Offered Rate (“LIBOR”) plus 280 basis points (4.57% and 4.21% at March 31, 2018 and December 31, 2017), reset quarterly, and are callable at par, at the option of the Company, quarterly. The Company used the proceeds of the offering for general corporate purposes.

On April 26, 2006, the Company completed the issuance and sale of $10 million of fixed/floating rate trust preferred securities through First Mid-Illinois Statutory Trust II (“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, 3.73% and 3.19% at March 31, 2018 and December 31, 2017, respectively). The net proceeds to the Company were used for general corporate purposes, including the Company’s acquisition of Mansfield Bancorp, Inc. in 2006.

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 $4,000,000 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 (3.98% and 3.44% at March 31, 2018 and December 31, 2017, 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 unconsolidated subsidiary of First BancTrust Corporation. The $6,000,000 of trust preferred securities and an additional $186,000 additional investment in common equity of FBTCST I is invested in junior subordinated debentures issued to FBTCST I. The subordinated debentures mature in 2035, bear interest at three-month LIBOR plus 170 basis points (3.82% and 3.29% at March 31, 2018 and December 31, 2017, respectively) and resets quarterly.

The trust preferred securities issued by Trust I, Trust II, CLST I and FBTCST I are included as Tier 1 capital of the Company for regulatory capital purposes.  On March 1, 2005, the Federal Reserve Board adopted a final rule that allows the continued limited inclusion of trust preferred securities in the calculation of Tier 1 capital for regulatory purposes.  The final rule provided a five-year transition period, ending September 30, 2010, for application of the revised quantitative limits. On March 17, 2009, the Federal Reserve Board adopted an additional final rule that delayed the effective date of the new limits on inclusion of trust preferred securities in the calculation of Tier 1 capital until March 31, 2012. The application of the revised quantitative limits did not and is not expected to have a significant impact on its calculation of Tier 1 capital for regulatory purposes or its classification as well-capitalized. The Dodd-Frank Act, signed into law July 21, 2010, removes trust preferred securities as a permitted component of a holding company’s Tier 1 capital after a three-year phase-in period beginning January 1, 2013 for larger holding companies. For holding companies with less than $15 billion in consolidated assets, existing issues of trust preferred securities are grandfathered and not subject to this new restriction. Similarly, the final rule implementing the Basel III reforms allows holding companies with less than $15 billion in consolidated assets as of December 31, 2009 to continue to count toward Tier 1 capital any trust preferred securities issued before May 19, 2010. New issuances of trust preferred securities, however would not count as Tier 1 regulatory capital.

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 Company does not currently anticipate that the Volcker Rule will have a material effect on the operations of the Company or First Mid Bank.

Interest Rate Sensitivity

The Company seeks to maximize its net interest margin while maintaining an acceptable level of interest rate risk.  Interest rate risk can be defined as the amount of forecasted net interest income that may be gained or lost due to changes in the interest rate environment, a variable over which management has no control. Interest rate risk, or sensitivity, arises when the maturity or repricing characteristics of interest-bearing assets differ significantly from the maturity or repricing characteristics of interest-bearing liabilities. The Company monitors its interest rate sensitivity position to maintain a balance between rate sensitive assets and rate sensitive liabilities.  This balance serves to limit the adverse effects of changes in interest rates.  The Company’s asset liability management committee (ALCO) oversees the interest rate sensitivity position and directs the overall allocation of funds.

60

In the banking industry, a traditional way to measure potential net interest income exposure to changes in interest rates is through a technique known as “static GAP” analysis which measures the cumulative differences between the amounts of assets and liabilities maturing or repricing at various intervals. By comparing the volumes of interest-bearing assets and liabilities that have contractual maturities and repricing points at various times in the future, management can gain insight into the amount of interest rate risk embedded in the balance sheet. The following table sets forth the Company’s interest rate repricing GAP for selected maturity periods at March 31, 2018 (dollars in thousands):

	Rate Sensitive Within																				Fair Value

Cumulative Ratio	(6.6		)%	(3.4		)%	1.2		%	8.9		%	14.3		%	22.6		%

The static GAP analysis shows that at March 31, 2018, the Company was liability sensitive, on a cumulative basis, through the twelve-month time horizon. This indicates that future increases in interest rates could have an adverse effect on net interest income. There are several ways the Company measures and manages the exposure to interest rate sensitivity, including static GAP analysis.  The Company’s ALCO also uses other financial models to project interest income under various rate scenarios and prepayment/extension assumptions consistent with First Mid Bank’s historical experience and with known industry trends.  ALCO meets at least monthly to review the Company’s exposure to interest rate changes as indicated by the various techniques and to make necessary changes in the composition terms and/or rates of the assets and liabilities.  The Company is currently experiencing downward pressure on asset yields resulting from the extended period of historically low interest rates and heightened competition for loans. A continuation of this environment could result in a decline in interest income and the net interest margin.

Capital Resources

At March 31, 2018, the Company’s stockholders' equity increased$3 million, or 1%, to $311 million from $308 million as of December 31, 2017. During the first three months of 2018, net income contributed $8.4 million to equity before the payment of dividends to stockholders. The change in market value of available-for-sale investment securities decreased stockholders' equity by $6.2 million, net of tax.

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 follows 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 measures established by regulatory capital standards to ensure capital adequacy require the the Company and its subsidiary bank to maintain a minimum capital amounts and ratios (set forth in the table below). Management believes that, as of March 31, 2018 and December 31, 2017, the Company and First Mid Bank met all capital adequacy requirements.

To be categorized as well-capitalized, 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 following table (dollars in thousands):

	Actual				Required Minimum For Capital Adequacy Purposes			To Be Well-Capitalized Under Prompt Corrective Action Provisions

The Company's risk-weighted assets, capital and capital ratios for March 31, 2018 are computed in accordance with Basel III capital rules which were effective January 1, 2015. Prior periods are computed following previous rules. See heading "Basel III" in the Overview section of this report for a more detailed description of the Basel III rules. As of March 31, 2018, both the Company and First Mid Bank had capital ratios above the required minimums for regulatory capital adequacy, and First Mid Bank had capital ratios that qualified it for treatment as well-capitalized under the regulatory framework for prompt corrective action with respect to banks.  

Stock Plans

Participants may purchase Company stock under the following four plans of the Company: the Deferred Compensation Plan, the First Retirement and Savings Plan, the Dividend Reinvestment Plan, and the Stock Incentive Plan.  For more detailed information on these plans, refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

At the Annual Meeting of Stockholders held April 26, 2017, the stockholders approved the 2017 Stock Incentive Plan ("SI Plan").  The SI Plan was implemented to succeed the Company’s 2007 Stock Incentive Plan, which had a ten-year term. The SI Plan is intended to provide a means whereby directors, employees, consultants and advisors of the Company and its Subsidiaries may sustain a sense of proprietorship and personal involvement in the continued development and financial success of the Company and its Subsidiaries, thereby advancing the interests of the Company and its stockholders.  Accordingly, directors and selected employees, consultants and advisors may be provided the opportunity to acquire shares of Common Stock of the Company on the terms and conditions established in the SI Plan.

A maximum of 149,983 shares of common stock may be issued under the SI Plan.  There were no stock options granted in 2017 or 2016.  The Company awarded 13,250 restricted stock awards during 2018 and 15,250 and 18,391 as stock unit awards during 2018 and 2017, respectively.

Employee Stock Purchase Plan

At the Annual Meeting of Stockholders held April 25, 2018, the stockholders approved the First Mid-Illinois Bancshares, Inc. Employee Stock Purchase Plan (“ESPP”).  The ESPP is intended to promote the interests of the Company by providing eligible employees with the opportunity to purchase shares of common stock of the Company at a 5% discount through payroll deductions. The ESPP is also intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code.  A maximum of 600,000 shares of common stock may be issued under the ESPP.  

Stock Repurchase Program

Since August 5, 1998, the Board of Directors has approved repurchase programs pursuant to which the Company may repurchase a total of approximately $76.7 million of the Company’s common stock.  The repurchase programs approved by the Board of Directors are as follows:

• On August 5, 1998, repurchases of up to 3%, or $2 million, of the Company’s common stock.

• In March 2000, repurchases up to an additional 5%, or $4.2 million of the Company’s common stock.

Since 1998, the Company has repurchased a total of 2,063,727 shares at a total price of approximately $70.3 million.  As of March 31, 2018, the Company is authorized per all repurchase programs to purchase $6.4 million in additional shares.

Liquidity

Liquidity represents the ability of the Company and its subsidiaries to meet all present and future financial obligations arising in the daily operations of the business.  Financial obligations consist of the need for funds to meet extensions of credit, deposit withdrawals and debt servicing.  The Company’s liquidity management focuses on the ability to obtain funds economically through assets that may be converted into cash at minimal costs or through other sources. The Company’s other sources of cash include overnight federal fund lines, Federal Home Loan Bank advances, deposits of the State of Illinois, the ability to borrow at the Federal Reserve Bank of Chicago, and the Company’s operating line of credit with The Northern Trust Company.  Details for the sources include:

• First Mid Bank has $35 million available in overnight federal fund lines, including $10 million from U.S. Bank, N.A., $10 million from Wells Fargo Bank, N.A. and $15 million from The Northern Trust Company.  Availability of the funds is subject to First Mid Bank meeting minimum regulatory capital requirements for total capital to risk-weighted assets and Tier 1 capital to total average assets.  As of March 31, 2018, First Mid Bank met these regulatory requirements.

• First Mid Bank can borrow from the Federal Home Loan Bank as a source of liquidity.  Availability of the funds is subject to the pledging of collateral to the Federal Home Loan Bank.  Collateral that can be pledged includes one-to-four family residential real estate loans and securities.  At March 31, 2018, the excess collateral at the FHLB would support approximately $127.0 million of additional advances for First Mid Bank.

• First Mid Bank is a member of the Federal Reserve System and can borrow funds provided that sufficient collateral is pledged.

• In addition, as of March 31, 2018, the Company had a revolving credit agreement in the amount of $10 million with The Northern Trust Company with an outstanding balance of $0 and $10 million in available funds.  This loan was renewed on April 13, 2018 for one year as a revolving credit agreement. The interest rate is floating at 2.25% over the federal funds rate. The loan is secured by all of the stock of First Mid Bank, including requirements for operating and capital ratios. The Company and its subsidiary bank were in compliance with the then existing covenants at March 31, 2018 and 2017 and December 31, 2017.

Management continues to monitor its expected liquidity requirements carefully, focusing primarily on cash flows from:

• lending activities, including loan commitments, letters of credit and mortgage prepayment assumptions;

• deposit activities, including seasonal demand of private and public funds;

• investing activities, including prepayments of mortgage-backed securities and call provisions on U.S. Treasury and government agency securities; and

• operating activities, including scheduled debt repayments and dividends to stockholders.

The following table summarizes significant contractual obligations and other commitments at March 31, 2018 (in thousands):

	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
Time deposits	$	342,215	$	215,769	$	98,917	$	26,421	$	1,108
Debt	33,995		3,750		5,625		—		24,620
Other borrowings	192,435		157,435		25,000		10,000		—
Operating leases	42,595		2,536		4,050		3,493		32,516
Supplemental retirement	581		100		131		100		250
	$	611,821	$	379,590	$	133,723	$	40,014	$	58,494

For the three months endedMarch 31, 2018, net cash of $10.7 million was provided from operating activities and $38.3 million and $6.5 million was used in investing activities and financing activities, respectively. In total, cash and cash equivalents decreased by $34.0 million since year-end 2017.

Off-Balance Sheet Arrangements

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 instruments.

The off-balance sheet financial instruments whose contract amounts represent credit risk at March 31, 2018 and December 31, 2017 were as follows (in thousands):

	March 31, 2018		December 31, 2017
Unused commitments and lines of credit:
Commercial real estate	$	41,511	$	73,268
Commercial operating	246,337		223,960
Home equity	37,784		38,318
Other	72,848		69,333
Total	$	398,480	$	404,879
Standby letters of credit	$	8,713	$	10,626

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.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There has been no material change in the market risk faced by the Company since December 31, 2017.  For information regarding the Company’s market risk, refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

ITEM 4.  CONTROLS AND PROCEDURES

The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by this report.  Based on such evaluation, such officers have concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures are effective.  Further, there have been no changes in the Company’s internal control over financial reporting during the last fiscal quarter that have materially affected or that are reasonably likely to affect materially the Company’s internal control over financial reporting.

PART II

ITEM 1. LEGAL PROCEEDINGS

On February 13, 2018, an alleged class action complaint was filed by a purported stockholder of First Bank in the United States District Court for the District of Delaware captioned Parshall v. First BancTrust Corporation (Case No. 1:18-cv-00218) against the Company, Merger Sub, First Bank and members of First Bank’s board of directors (the “Lawsuit”). The Lawsuit related to the Agreement and Plan of Merger, dated as of December 11, 2017 (as amended by the First Amendment to Agreement and Plan of Merger entered into as of January 18, 2018), among the Company, Merger Sub and First Bank and the merger contemplated thereby (the “Merger”). Among other things, the Lawsuit alleged that the Registration Statement on Form S-4 filed with the SEC by the Company on January 22, 2018 failed to disclose allegedly material information relating to the Company’s and First Bank’s financial projections, the analyses performed by First Bank’s financial advisor, and alleged potential conflicts of interest of First Bank’s officers, directors and financial advisor.  The plaintiff sought, among other relief, to enjoin the Merger from proceeding. The Company believes that the factual allegations in the Lawsuit were without merit.

On March 9, 2018, in order to moot plaintiff’s disclosure claims, reduce the expenses, burdens, risks and uncertainties inherent in litigation and avoid the risk of delaying or adversely affecting the Merger, in exchange for the plaintiff agreeing to withdraw the Lawsuit and dismiss his claims with prejudice, the Company and First Bank made additional supplemental disclosures to the proxy statement/prospectus related to the Merger that was first mailed to stockholders of First Bank on or about February 9, 2018. The agreement between the parties did not release or otherwise prejudice any potential claims of any member of the putative class other than the plaintiff and did not constitute any admission by any of the defendants as to the merits of any claims. In addition, in connection with the mootness of the disclosure claims, the parties contemplate that plaintiff’s counsel will seek an award of attorneys’ fees and expenses.

From time to time the Company and its subsidiaries may be involved in litigation that the Company believes is a type common to our industry. None of any such existing claims are believed to be individually material at this time to the Company, although the outcome of any such existing claims cannot be predicted with certainty.

ITEM 1A.  RISK FACTORS

Various risks and uncertainties, some of which are difficult to predict and beyond the Company’s control, could negatively impact the Company.  As a financial institution, the Company is exposed to interest rate risk, liquidity risk, credit risk, operational risk, risks from economic or market conditions, and general business risks among others.  Adverse experience with these or other risks could have a material impact on the Company’s financial condition and results of operations, as well as the value of its common stock.  See the risk factors and “Supervision and Regulation” described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of accounting and consolidation

Basis of Accounting and Consolidation

The unaudited condensed consolidated financial statements include the accounts of First Mid-Illinois Bancshares, Inc. (“Company”) and its wholly-owned subsidiaries:  First Mid-Illinois Bank & Trust, N.A. (“First Mid Bank”), Mid-Illinois Data Services, Inc. (“MIDS”) and The Checkley Agency, Inc. doing business as First Mid Insurance Group (“First Mid Insurance”).  All significant intercompany balances and transactions have been eliminated in consolidation.   The financial information reflects all adjustments which, in the opinion of management, are necessary for a fair presentation of the results of the interim periods ended March 31, 2018 and 2017, and all such adjustments are of a normal recurring nature.  Certain amounts in the prior year’s consolidated financial statements have been reclassified to conform to the March 31, 2018 presentation and there was no impact on net income or stockholders’ equity.  The results of the interim period ended March 31, 2018 are not necessarily indicative of the results expected for the year ending December 31, 2018. The Company operates as a one-segment entity for financial reporting purposes.

The 2017 year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

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 financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2017 Annual Report on Form 10-K.

Website

The Company maintains a website at www.firstmid.com. All periodic and current reports of the Company and amendments to these reports filed with the Securities and Exchange Commission (“SEC”) can be accessed, free of charge, through this website as soon as reasonably practicable after these materials are filed with the SEC.

At-The-Market Program

On August 16, 2017, the Company entered into a Sales Agency Agreement, pursuant to which the Company may sell, from time to time, up to an aggregate of $20 million of it's common stock. Shares of common stock are offered pursuant to the Company's shelf registration statement filed within the SEC. During the three ended March 31, 2018, the company sold no shares of common stock under the program. As of March 31, 2018, approximately $16.53 million of common stock remained available for issuance under the At The Market program.

Agreement and Plan of Merger

On December 11, 2017, the Company and Project Hawks Merger Sub LLC (formerly known as Project Hawks Merger Sub Corp.), a newly formed Delaware limited liability company and wholly-owned subsidiary of the Company (“Merger Sub”), entered into an Agreement and Plan of Merger (as amended as of January 18, 2018, the “Merger Agreement") with First BancTrust Corporation, a Delaware corporation (“First Bank”), pursuant to which, among other things, the Company agreed to acquire 100% of the issued and outstanding shares of First Bank pursuant to a business combination whereby First Bank will merge with and into Merger Sub, with Merger Sub as the surviving entity 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 $0.01 per share, of First Bank issued and outstanding immediately prior to the effective time of the Merger (other than shares held in treasury by First Bank and shares held by stockholders who have properly made and not withdrawn a demand for appraisal rights under Delaware law) converted into and become the right to receive, (a) $5.00 in cash and (b) 0.800 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 adjustments, all as set forth in the Merger Agreement. As of March 31, 2018, First Bank had total consolidated assets of $479.2 million, loans of $369.6 million and total deposits of $391.6 million.

Subsequently, the Merger closed on May 1, 2018. The Company issued an aggregate total of 1,643,900 shares of common stock at $37.32 per share and approximately $10,275,000, including cash in lieu of fractional shares. The accounting for the Merger is incomplete as the Company is still determining the fair value of assets acquired and liabilities assumed.

It is anticipated that First Bank’s wholly-owned bank subsidiary, First Bank & Trust, IL (“First Bank & Trust”), will be merged with and into the Company’s wholly owned bank subsidiary First Mid Bank later in 2018. At the time of the bank merger, First Bank & Trust’s banking offices will become branches of First Mid Bank.

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.

Stock Plans

At the Annual Meeting of Stockholders held April 26, 2017, the stockholders approved the First Mid-Illinois Bancshares, Inc. 2017 Stock Incentive Plan (“SI Plan”).  The SI Plan was implemented to succeed the Company’s 2007 Stock Incentive Plan, which had a ten-year term. The SI Plan is intended to provide a means whereby directors, employees, consultants and advisors of the Company and its subsidiaries may sustain a sense of proprietorship and personal involvement in the continued development and financial success of the Company and its subsidiaries, thereby advancing the interests of the Company and its stockholders.  Accordingly, directors and selected employees, consultants and advisors may be provided the opportunity to acquire shares of common stock of the Company on the terms and conditions established in the SI Plan.

A maximum of 149,983 shares of common stock may be issued under the SI Plan. There have been no stock options awarded under any Company plan since 2008. The Company has awarded 13,250 shares of restricted stock during 2018 and 15,250 and 18,391 restricted stock units during 2018 and 2017, respectively.

Employee Stock Purchase Plan

At the Annual Meeting of Stockholders held April 25, 2018, the stockholders approved the First Mid-Illinois Bancshares, Inc. Employee Stock Purchase Plan (“ESPP”).  The ESPP is intended to promote the interests of the Company by providing eligible employees with the opportunity to purchase shares of common stock of the Company at a 5% discount through payroll deductions. The ESPP is also intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code.  A maximum of 600,000 shares of common stock may be issued under the ESPP.  

Revenue Recognition

Accounting Standards Codification 606, Revenue from Contracts with Customers (“ASC 606”), establishes a revenue recognition model for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. Most of the Company’s revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans and investment securities, and revenue related to mortgage servicing activities, which are subject to other accounting standards. A description of the revenue-generating activities that are within the scope of ASC 606, and included in other income in the Company’s condensed consolidated statements of income are as follows:

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 Group (“FMIG”), receives commissions on premiums of new and renewed business policies. FMIG records commission revenue on direct bill policies as the cash is received. For agency bill policies, FMIG 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.

Accumulated Other Comprehensive Income (Loss)

The components of accumulated other comprehensive income (loss) included in stockholders’ equity as of March 31, 2018 and December 31, 2017 are as follows (in thousands):

	Unrealized Gain (Loss) on Securities			Securities with Other-Than-Temporary Impairment Losses			Total

Consolidation

The unaudited condensed consolidated financial statements include the accounts of First Mid-Illinois Bancshares, Inc. (“Company”) and its wholly-owned subsidiaries:  First Mid-Illinois Bank & Trust, N.A. (“First Mid Bank”), Mid-Illinois Data Services, Inc. (“MIDS”) and The Checkley Agency, Inc. doing business as First Mid Insurance Group (“First Mid Insurance”).  All significant intercompany balances and transactions have been eliminated in consolidation.   The financial information reflects all adjustments which, in the opinion of management, are necessary for a fair presentation of the results of the interim periods ended March 31, 2018 and 2017, and all such adjustments are of a normal recurring nature.  Certain amounts in the prior year’s consolidated financial statements have been reclassified to conform to the March 31, 2018 presentation and there was no impact on net income or stockholders’ equity.  The results of the interim period ended March 31, 2018 are not necessarily indicative of the results expected for the year ending December 31, 2018. The Company operates as a one-segment entity for financial reporting purposes.

The 2017 year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

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 financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2017 Annual Report on Form 10-K.

Adoption of new accounting guidance

Adoption of New Accounting Guidance

Accounting Standards Update 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification ("ASU 2017-09"). In May 2017, FASB issued ASU 2017-09. This update provides guidance on determining which changes to the terms and conditions of share-based payment awards require the application of modification accounting under Topic 718. The guidance is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The amendments should be applied on a prospective basis to an award modified on or after adoption date. ASU 2017-09 did not have a significant impact on the Company's consolidated financial statement.

Accounting Standards Update 2017-08, Receivables-Nonrefundable Fees and Other Costs ("ASU 2017-08"). In March 2017, FASB issued ASU 2017-08. This update amends the amortization period for certain purchased callable debt securities held at a premium. The update shortens the premium's amortization period to the earliest call date to more closely align the amortization period of premiums to expectations incorporated in market pricing on the underlying securities. For public companies, the update is effective for annual periods beginning after December 15, 2018, and is to be applied on a modified retrospective basis with a cumulative-effect adjustment directly to retained earnings as of the beginning of the adoption period. Early adoption is permitted, including adoption in an interim period. The Company adopted ASU 2017-08 early and there was not a significant impact on the Company's consolidated financial statements.

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 consolidated financial statements. The current accounting policies and procedures of the Company are not anticipated to change, except for the elimination of the Step 2 analysis.

Accounting Standards Update 2016-08, Revenue from Contracts with Customers (Topic 606) (“ASU 2016-08"). In March 2016, the FASB issued ASU 2016-08 which amended the accounting guidance issued by the FASB in May 2014 that revised the criteria for determining when to recognize revenue from contracts with customers and expanded disclosure requirements. The amendment defers the effective date by one year. This accounting guidance can be implemented using either a retrospective method or a cumulative-effect approach. This new guidance is effective for interim and annual reporting periods beginning after December 15, 2017. The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including trust and asset management fees, deposit related fees, interchange fees, merchant income, and annuity and insurance commissions. Based on this assessment, the Company concluded that ASU 2014-09 did not materially change the method in which the Company currently recognizes revenue for these revenue streams.

Accounting Standards Update 2016-01, Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). In January 2016, FASB issued ASU 2016-01 which amends prior guidance to require an entity to measure its equity investments (except those accounted for under the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. An entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of same issuer. The new guidance simplifies the impairment assessment of equity investments without readily determinable fair values, requires public entities to use the exit price notion when measuring fair value of financial instruments for disclosure purposes, requires an entity to present separately in other comprehensive income the portion of the total change in fair value of a liability resulting from changes in the instrument-specific credit risk when the entity has selected fair value option for financial instruments and requires separate presentation of financial assets and liabilities by measurement category and form of financial asset. The new guidance is effective for reporting periods after January 1, 2018 and did not have a significant impact on the Company's consolidated financial statements other than adoption of the standard resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis. See Note 7 - Fair Value of Assets and Liabilities for further information regarding the valuation of these loans.

Pending New Accounting Guidance

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 will be 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 will be 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. Early adoption is permitted for all entities. Management continues to evaluate the impact ASU 2016-02 will have 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. 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. Management has formed an internal committee to evaluate implementation steps and assess the impact ASU 2016-13 will have on the Company’s consolidated financial statements. The committee has assigned roles and responsibilities, key tasks to complete, and has established a general timeline for implementation. The Company has 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 meets periodically to discuss the latest developments and ensure progress is being made. The team also keeps current on evolving interpretations and industry practices related to ASU 2016-13. The committee continues to evaluate and validate data resources and different loss methodologies. The committee is still evaluating the impact ASU 2016-13 will have on the Company's consolidated financial statements.

Earnings Per Share

Basic net income per common share available to common stockholders is calculated as net income less preferred stock dividends divided by the weighted average number of common shares outstanding.  Diluted net income per common share available to common stockholders is computed using the weighted average number of common shares outstanding, increased by the assumed conversion of the Company’s convertible preferred stock and the Company’s stock options, unless anti-dilutive.

The components of basic and diluted net income per common share available to common stockholders for the three-month period ended March 31, 2018 and 2017 were as follows:

Trust preferred securities represents one trust preferred pooled security issued by First Tennessee Financial (“FTN”). The unrealized loss of this security, which has a remaining maturity of twenty years, is primarily due to its long-term nature, a lack of demand or inactive market for the security, and concerns regarding the underlying financial institutions that have issued the trust preferred security. See the heading “Trust Preferred Securities” for further information regarding this security.

U.S. Treasury Securities and Obligations of U.S. Government Corporations and Agencies. At March 31, 2018 there were eleven available-for sale U.S. Treasury securities and obligations of U.S. government corporations and agencies with a fair value of $47,373,000 and unrealized losses of $2,095,000 in a continuous unrealized loss position for twelve months or more. At December 31, 2017 , there were eleven available-for sale U.S. Treasury securities and obligations of U.S. government corporations and agencies with a fair value of $47,972,000 and unrealized losses of $1,494,000 in a continuous unrealized loss position for twelve months or more. At March 31, 2018 there were seven held-to-maturity U.S. Treasury securities and obligations of U.S. government corporations and agencies with a fair value of $38,137,000 and unrealized losses of $1,422,000 in a continuous unrealized loss position for twelve months or more. At December 31, 2017 there were seven held-to-maturity U.S. Treasury securities and obligations of U.S. government corporations and agencies with a fair value of $14,540,000 and unrealized losses of $453,000 in a continuous unrealized loss position for twelve months or more.

Obligations of states and political subdivisions.  At March 31, 2018 there were thirty-three obligations of states and political subdivisions with a fair value of $14,901,000 and unrealized losses of $882,000 in a continuous loss position for twelve months or more. At December 31, 2017, there were thirty-nine obligations of states and political subdivisions with a fair value of $9,267,000 and unrealized losses of $256,000 in a continuous unrealized loss position for twelve months or more.

Mortgage-backed Securities: GSE Residential. At March 31, 2018 there were twenty-seven mortgage-backed securities with a fair value of $66,119,000 and unrealized losses of $2,791,000 in a continuous unrealized loss position for twelve months or more. At December 31, 2017, there were twenty-six mortgage-backed securities with a fair value of $22,609,000 and unrealized losses of $518,000 in a continuous unrealized loss position for twelve months or more.

Trust Preferred Securities. At March 31, 2018, there was one trust preferred security with a fair value of $2,522,000 and unrealized loss of $327,000 in a continuous unrealized loss position for twelve months or more. At December 31, 2017, there was one trust preferred security with a fair value of $2,548,000 and unrealized loss of $345,000 in a continuous unrealized loss position for twelve months or more. The unrealized loss was primarily due to the long-term nature of the trust preferred security, a lack of demand or inactive market for the security, the impending change to the regulatory treatment of these securities, and concerns regarding the underlying financial institutions that have issued the trust preferred securities.

The Company recorded no other-than-temporary impairment (OTTI) for these securities during 2018 or 2017.   Because it is not more-likely-than-not that the Company will be required to sell the remaining security before recovery of its new, lower amortized cost basis, which may be maturity, the Company does not consider the remainder of the investment to be other-than-temporarily impaired at March 31, 2018. However, future downgrades or additional deferrals and defaults in this security, could result in additional OTTI and consequently, have a material impact on future earnings.

Following are the details for the currently impaired trust preferred security (in thousands):

	Book Value		Fair Value		Unrealized Gains (Losses)			Other-than- temporary Impairment Recorded To-date
PreTSL XXVIII	$	2,849	$	2,522	$	(327	)	$	(1,111	)

Other securities. At March 31, 2018 and December 31, 2017, there were no other securities in a continuous unrealized loss position for twelve months or more.

The Company does not believe any other individual unrealized loss as of March 31, 2018 represents OTTI. However, given the continued disruption in 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.

Other-than-temporary Impairment. Upon acquisition of a security, the Company determines whether it is within the scope of the accounting guidance for investments in debt and equity securities or whether it must be evaluated for impairment under the accounting guidance for beneficial interests in securitized financial assets.

The Company conducts periodic reviews to evaluate its investment securities to determine whether OTTI has occurred. While all securities are considered, the securities primarily impacted by OTTI evaluation are pooled trust preferred securities. For the pooled trust preferred security currently in the investment portfolio, an extensive review is conducted to determine if any additional OTTI has occurred. The Company utilizes an independent third-party to perform the OTTI evaluation. The Company's management reviews the assumption inputs and methodology with the third-party to obtain an understanding of them and determine if they are appropriate for the evaluation. Economic models are used to project future cash flows for the security based on current assumptions for discount rate, prepayments, default and deferral rates and recoveries. These assumptions are determined based on the structure of the issuance, the specific collateral underlying the security, historical performance of trust preferred securities and general state of the economy. The OTTI test compares the present value of the cash flows from quarter to quarter to determine if there has been an adverse change which could indicate additional OTTI.

The discount rate assumption used in the cash flow model is equal to the current yield used to accrete the beneficial interest. The Company’s current trust preferred security investment has a floating rate coupon of 3-month LIBOR plus 90 basis points. Since the estimate of 3-month LIBOR is based on the forward curve on the measurement date, and is therefore variable, the discount assumption for this security is a range of projected coupons over the expected life of the security.

The Company considers the likelihood that issuers will prepay their securities which changes the amount of expected cash flows. Factors such as the coupon rates of collateral, economic conditions and regulatory changes, such as the Dodd-Frank Act and Basel III, are considered.

The trust preferred security includes collateral issued by financial institutions and insurance companies. To identify bank issuers with a high risk of near term default or deferral, a credit model developed by the third-party is utilized that scores each bank issuer based on 29 different ratios covering capital adequacy, asset quality, earnings, liquidity, the Texas Ratio, and sensitivity to interest rates. To account for longer term bank default risk not captured by the credit model, it is assumed that banks will default at a rate of 2% annually for the first two years of the cash flow projection, and 36 basis points in each year thereafter. To project defaults for insurance issuers, each issuer’s credit rating is mapped to its idealized default rate, which is AM Best’s estimate of the historical default rate for insurance companies with that rating.

Lastly, it is assumed that trust preferred securities issued by banks that have already failed will have no recoveries, and that banks projected to default will have recoveries of 10%. Additionally, the 10% recovery assumption, incorporates the potential for cures by banks that are currently in deferral.

If the Company determines that a given pooled trust preferred security position will be subject to a write-down or loss, the Company records the expected credit loss as a charge to earnings.

Credit Losses Recognized on Investments. As described above, the Company’s investment in trust preferred security has experienced fair value deterioration due to credit losses but is not otherwise other-than-temporarily impaired.

Loans and Allowance for Loan Losses

Loans and Allowance for Loan Losses

Loans are stated at the principal amount outstanding net of unearned discounts, unearned income and allowance for loan 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. A summary of loans at March 31, 2018 and December 31, 2017 follows (in thousands):

Net loans increased$37.1 million as of March 31, 2018 compared to December 31, 2017. The increase was primarily due to increases in commercial real estate loans, commercial and industrial loans, and all other loans offset by seasonal declines in agricultural loans. 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 market value, taking into consideration future commitments to sell the loans. These loans are primarily for 1-4 family residential properties. 

Most of the Company’s business activities are with customers located near the Company's branch locations in Illinois and Missouri.  At March 31, 2018, the Company’s loan portfolio included $196.9 million of loans to borrowers whose businesses are directly related to agriculture. Of this amount, $158.3 million was concentrated in other grain farming. Total loans to borrowers whose businesses are directly related to agriculture decreased$16.9 million from $213.8 million at December 31, 2017 due to seasonal paydowns based upon timing of cash flow requirements. Loans concentrated in other grain farming decreased$12.5 million from $170.8 million at December 31, 2017.  While the Company adheres to sound underwriting practices, including 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 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 $118.4 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 $187.4 million of loans to lessors of non-residential buildings, $131.3 million of loans to lessors of residential buildings and dwellings, and $97.8 million of loans to other gambling industries.

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 the vast majority of 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. 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.

Purchase Credit-Impaired Loans. Loans acquired with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit impaired. Evidence of credit quality deterioration as of the purchase date may include information such as past-due and nonaccrual status, borrower credit scores and recent loan to value percentages. Purchase credit-impaired ("PCI") loans are accounted for under ASC 310-30, Receivables--Loans and Debt Securities Acquired with Deteriorated Credit Quality ("ASC 310-30"), and are initially measured at fair value, which includes 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 is 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.

Allowance for Loan Losses

The allowance for loan losses represents the Company’s best estimate of the reserve necessary to adequately account for probable losses existing in the current portfolio. The provision for loan losses is the charge against current earnings that is determined by the Company as the amount needed to maintain an adequate allowance for loan losses. In determining the adequacy of the allowance for loan 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 loan losses by separately evaluating large impaired loans and nonimpaired loans.

The Company has loans acquired from business combinations with uncollected principal balances.  These loans are carried net of a fair value adjustment for credit risk and interest rates and are only included in the allowance calculation to the extent that the reserve requirement exceeds the fair value adjustment.  However, as the acquired loans renew, it is necessary to establish an allowance which represents an amount that, in management’s opinion, will be adequate to absorb probable credit losses inherent in such 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, 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 effective interest rate; (2) the loan’s observable market price, if available; or (3) the fair value of the collateral less costs to sell for collateral dependent loans and loans for which foreclosure is deemed to be probable. A specific allowance is assigned when expected cash flows or collateral do not justify the carrying amount of the loan. The carrying value of the loan reflects reductions from prior charge-offs.

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. Determining the appropriate level of the allowance for loan losses for all non-impaired loans is based on a migration analysis of net losses over a rolling twelve quarter period by loan segment. A weighted average of the net losses is 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. Environmental factors including 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 are evaluated each quarter to determine if adjustments to the weighted average historical net losses is appropriate given these current influences on the risk profile of each loan segment. 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 periodically assessed and adjusted when appropriate. Consumer loans are evaluated for adverse classification based primarily on the Uniform Retail Credit Classification and Account Management Policy established by the federal banking regulators. Classification standards are generally based on delinquency status, collateral coverage, bankruptcy and the presence of fraud.

Due to weakened economic conditions during prior 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 has not materially changed any aspect of its overall approach in the determination of the allowance for loan losses.  However, on an on-going basis the Company continues to refine the methods used in determining management’s best estimate of the allowance for loan losses.

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 all loan portfolio segments except 1-4 family residential properties and consumer, the Company promptly charges-off loans, or portions thereof, when available information confirms that specific loans are uncollectible based on information that includes, but is not limited to, (1) the deteriorating financial condition of the borrower, (2) declining collateral values, and/or (3) legal action, including bankruptcy, that impairs the borrower’s ability to adequately meet its obligations. For impaired loans that are considered to be solely collateral dependent, a partial charge-off is recorded when a loss has been confirmed by an updated appraisal or other appropriate valuation of the collateral.

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.

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, 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.

Impaired Loans

Within all loan portfolio segments, loans are 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 Company’s policy is to discontinue the accrual of interest income on all loans for which principal or interest is ninety days past due.  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 amount of interest income recognized by the Company within the periods stated above was due to loans modified in troubled debt restructurings that remained on accrual status.  The balance of loans modified in troubled debt restructurings included in the impaired loans at March 31, 2018 stated above that were still accruing was $730,000 of 1-4 Family residential properties, $249,000 of commercial real estate and $20,000 of commercial & industrial loans. The balance of loans modified in a troubled debt restructurings at March 31, 2017 included in the impaired loans stated above that were still accruing was $597,000 of 1-4 family residential properties, $3,407,000 of multifamily residential properties, $2,121,000 commercial real estate, $37,000 commercial and industrial loans, and $3,000 of consumer loans. For the three months ended March 31, 2018 and 2017, the amount of interest income recognized using a cash-basis method of accounting during the period that the loans were impaired was not material.

Non Accrual Loans

The following table presents the Company’s recorded balance of nonaccrual loans as March 31, 2018 and December 31, 2017 (in thousands). This table excludes purchased impaired loans and performing troubled debt restructurings.

Interest income that would have been recorded under the original terms of such nonaccrual loans totaled $608,000 and $287,000 for the three months ended March 31, 2018 and 2017, respectively.

Purchased Credit-Impaired Loans

The Company acquired certain loans considered to be credit-impaired ("PCI") in its business combination with First Clover Leaf during the third quarter of 2016. At acquisition, these loans evidenced deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. The carrying amount of these loans is included in the consolidated balance sheet amounts for Loans. The Company had no PCI loans prior to the First Clover Leaf acquisition. The amount of these loans at March 31, 2018 and December 31, 2017 are as follows (in thousands):

	March 31, 2018		December 31, 2017
Commercial real estate	249		251
Commercial and industrial loans	4		8
Carrying amount	253		259
Allowance for loan losses	5		9
Carrying amount, net of allowance	$	248	$	250

As of September 8, 2016, the acquisition date, the principal outstanding of PCI loans totaled $10,650,000 and the fair value of PCI loans totaled $8,688,000. For PCI loans, the difference between contractually required payments at acquisition and the cash flow expected to be collected is referred to as the non-accretable difference. Any excess of expected cash flows over the fair value is referred to as the accretable yield. As of March 31, 2018 there is no accretable yield on the PCI loans acquired. Subsequent decreases to the expected cash flows will result in a provision for loan and lease losses. Subsequent increases in expected cash flows will result in a reversal of the provision for loan and lease losses to the extent of prior charges and then an adjustment to accretable yield, which would have a positive impact on interest income. As of March 31, 2018, there was one loan with a change in expected cash flows and as a result, approximately $5,000 of provision was recorded. As of December 31, 2017, there was one loan with a change in expected cash flows and as a result, approximately $9,000 of provision was recorded.

Troubled Debt Restructuring

The balance of troubled debt restructurings ("TDRs") at March 31, 2018 and December 31, 2017 was $8.2 million and $8.9 million, respectively.  There was $32,000 and $37,000 in specific reserves established with respect to these loans as of March 31, 2018 and December 31, 2017, respectively. As troubled debt restructurings, these loans are included in nonperforming loans and are classified as impaired which requires that they be individually measured for impairment. The modification of the terms of these loans included one or a combination of the following: a reduction of stated interest rate of the loan; an extension of the maturity date and change in payment terms; or a permanent reduction of the recorded investment in the loan. The following table presents the Company’s recorded balance of troubled debt restructurings at March 31, 2018 and December 31, 2017 (in thousands).

Troubled debt restructurings:	March 31, 2018		December 31, 2017

Total	1	$	161		—	$	—

Type of modifications:

(a) Reduction of stated interest rate of loan

(b) Change in payment terms

(c) Extension of maturity date

(d) Permanent reduction of the recorded investment

A loan is considered to be in payment default once it is 90 days past due under the modified terms.  There were no loans modified as troubled debt restructurings during the prior twelve months that experienced defaults for three months ended March 31, 2018. There was one loan modified as troubled debt restructuring during the prior twelve months that experienced defaults as of December 31, 2017.

The balance of real estate owned includes $1,951,000 and $2,754,000 of foreclosed real estate properties recorded as a result of obtaining physical possession of the property at March 31, 2018 and December 31, 2017, respectively. The recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceeds are in process was $938,000 and $404,000 at March 31, 2018 and December 31, 2017, respectively.

Repurchase Agreements and Other Borrowings

Securities sold under agreements to repurchase were $132.4 million at March 31, 2018, a decrease of $23.0 million from $155.4 million at December 31, 2017. The decrease during the first three months of 2018 was primarily due to decreases in balances of customers due to changes in cash flow needs for their businesses. All of the transactions have overnight maturities with a weighted average rate of 0.14%.

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.

Collateral pledged by class for repurchase agreements are as follows (in thousands):

	March 31, 2018		December 31, 2017
US Treasury securities and obligations of U.S. government corporations & agencies	$	87,378	$	100,895

Fair Value of Assets and Liabilities

Fair Value Disclosures [Abstract]

Fair Value of Assets and Liabilities

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 and include subordinated tranches of collateralized mortgage obligations and investments in trust preferred securities.

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.

The trust preferred securities are collateralized debt obligation securities that are backed by trust preferred securities issued by banks, thrifts, and insurance companies. The market for these securities at March 31, 2018 is not active and markets for similar securities are also not active. The inactivity was evidenced first by a significant widening of the bid-ask spread in the brokered markets in which trust preferred securities trade and then by a significant decrease in the volume of trades relative to historical levels. The new issue market is also inactive and will continue to be, as a result of the Dodd-Frank Act’s elimination of trust preferred securities from Tier 1 capital for certain holding companies. There are currently very few market participants who are willing and or able to transact for these securities. The market values for these securities are very depressed relative to historical levels. Given conditions in the debt markets today and the absence of observable transactions in the secondary and new issue markets, we determined:

• The few observable transactions and market quotations that are available are not reliable for purposes of determining fair value at March 31, 2018,

• An income valuation approach technique (present value technique) that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs will be equally or more representative of fair value than the market approach valuation technique used at prior measurement dates, and

• The trust preferred securities held by the Company will be classified within Level 3 of the fair value hierarchy because we determined that significant adjustments are required to determine fair value at the measurement date.

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 March 31, 2018 and December 31, 2017 (in thousands):

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 March 31, 2018 was $3,996,000 and a fair value of $3,489,000 resulting in specific loss exposures of $507,000.

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 March 31, 2018 was $1,951,000. Other real estate owned included in the total carrying amount and measured at fair value on a nonrecurring basis during the period amounted to $24,000.

The following table presents the fair value measurement of assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at March 31, 2018 and December 31, 2017 (in thousands):

Sensitivity of Significant Unobservable Inputs

The following is a discussion of the sensitivity of significant unobservable inputs, the interrelationships between those inputs and other unobservable inputs used in recurring fair value measurement and of how those inputs might magnify or mitigate the effect of changes in the unobservable inputs on the fair value measurement.

Trust Preferred Securities. The significant unobservable inputs used in the fair value measurement of the Company’s trust preferred securities are offered quotes and comparability adjustments.  Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement.  Generally, changes in either of those inputs will not affect the other input.

The following table presents quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements other than goodwill at June 30, 2017 and December 31, 2016 (in thousands).

March 31, 2018	Fair Value		Valuation Technique	Unobservable Inputs	Range (Weighted Average)
Trust Preferred Securities	$	2,522	Discounted cash flow	Discount rate	11.7%

Other. The following methods were used to estimate the fair value of all other financial instruments recognized in the accompanying balance sheets at amounts other than fair value.

Cash and Cash Equivalents, Federal Funds Sold, Interest Receivable and Federal Reserve and Federal Home Loan Bank Stock. The carrying amount approximates fair value.

Certificates of Deposit Investments. The fair value of certificates of deposit investments is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities.

Held-to-Maturity Securities. Fair Value is based on quoted market prices, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities.

Loans Held for Sale. Loans expected to be sold are classified as held for sale and are recorded at the lower of aggregate cost or market value.

Loans. For March 31, 2018, fair value of loans is estimated on an exit price basis incorporating discounts for credit, liquidity and marketability factors. This is not comparable with the fair values disclosed for December 31, 2017, which were based on an entrance price basis. For that date, fair values of variable rate loans that reprice frequently and with no significant change in credit risk were based on carrying values. The fair values of other loans as of that date were estimated using discounted cash flow analyses which used interest rates then being offered for loans with similar terms to borrowers of similar credit quality. The carrying amount of accrued interest approximates its fair value.

Deposits. Deposits include demand deposits, savings accounts, NOW accounts and certain money market deposits. The carrying amount of these deposits approximates fair value. The fair value of fixed-maturity time deposits is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities.

Securities Sold Under Agreements to Repurchase. The fair value of securities sold under agreements to repurchased is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities.

Interest Payable. The carrying amount approximates fair value.

Junior Subordinated Debentures, Federal Home Loan Bank Borrowings and Other Borrowings. Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt.

The following tables present estimated fair values of the Company’s financial instruments at March 31, 2018 and December 31, 2017 in accordance with FAS 107-1 and APB 28-1, codified with ASC 805 (in thousands):
