Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The following is a summary of the accounting policies adopted by Civista Bancshares, Inc., which have a significant effect on the Consolidated Financial Statements. Nature of Operations and Principles of Consolidation Civista provides financial services through its offices in the Ohio counties of Erie, Crawford, Champaign, Cuyahoga, Franklin, Logan, Summit, Huron, Ottawa, Madison, Montgomery and Richland, in the Indiana counties of Dearborn and Ripley and in the Kentucky county of Kenton. Its primary deposit products are checking, savings, and term certificate accounts, and its primary lending products are residential mortgage, commercial, and installment loans. Substantially all loans are secured by specific items of collateral including business assets, consumer assets and commercial and residential real estate. Commercial loans are expected to be repaid from cash flow from operations of businesses. There are no significant concentrations of loans to any one industry or customer. However, our customers’ ability to repay their loans is dependent on the real estate and general economic conditions in the area. Other financial instruments that potentially represent concentrations of credit risk include deposit accounts in other financial institutions. FCIA was formed to allow the Company to participate in commission revenue generated through its third party insurance agreement. Insurance commission revenue was less than 1.0% of total revenue for the years ended December 31, 2018, 2017 and 2016. WSP was formed to hold repossessed assets of CBI’s subsidiaries. WSP revenue was less than 1% of total revenue for the years ended December 31, 2018, 2017 and 2016. FCRS was formed in 2012 and remained inactive for the periods presented. CRMI was formed in 2017 to provide property and casualty insurance coverage to CBI and its’ subsidiaries for which insurance may not be currently available or economically feasible in the insurance marketplace. CRMI revenue was less than 1% of total revenue for the years ended December 31, 2018 and 2017. Use of Estimates Cash Flows Securities NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) On January 1, 2018, the Company adopted the new accounting standard for Financial Instruments, which requires equity securities to be measured at fair value with the changes in fair value recognized in net income. The adoption of this guidance resulted in a $278 increase in retained earnings and a $278 decrease in to accumulated other comprehensive income. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are based on the amortized cost of the security sold using the specific identification method. Under U.S. generally accepted accounting principles (“GAAP”) guidance, if (a) a company does not have the intent to sell a debt security prior to recovery and (b) it is more-likely-than-not that it will not have to sell the debt security prior to recovery, the security would not be considered other-than-temporarily impaired unless there is a credit loss. When an entity does not intend to sell the security, and it is more-likely-than-not the entity will not have to sell the security before recovery of its cost basis, it will recognize the credit component of other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of other-than-temporary impairment recorded in other comprehensive income for the non-credit portion of a previous other-than-temporary impairment should be amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security. For available-for-sale debt securities that management has no intent to sell and believes that it more-likely-than-not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the non-credit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections. Other securities which include FHLB stock, Federal Reserve Bank (“FRB”) stock, Federal Agricultural Mortgage Corporation stock, Bankers’ Bancshares Inc. (“BB”) stock, and Norwalk Community Development Corp (“NCDC”) stock are carried at cost. Loans Held for Sale: Loans: Interest income on mortgage and commercial loans is discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection. Interest income on consumer loans is discontinued when management determines future collection is unlikely. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued, but not received, for loans placed on nonaccrual, is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Purchased Loans: Purchased loans are accounted for individually or aggregated into pools of loans based on common risk characteristics (e.g., credit score, loan type, and date of origination). The Company estimates the amount and timing of expected cash flows for each purchased loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield). The excess of the loan’s, or pool’s, contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan or pool, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded. If the present value of expected future cash flows is greater than the carrying amount, the excess is recognized as part of future interest income. Allowance for Loan Losses: All commercial, commercial real estate and farm real estate loans are monitored on a regular basis with a detailed loan review completed for all loan relationships greater than $750. All commercial, commercial real estate and farm real estate loans that are 90 days past due or in nonaccrual status, are analyzed to determine if they are “impaired”, which means that it is probable that all amounts will not be collected according to the contractual terms of the loan agreement. All loans that are delinquent 90 days are classified as substandard and placed on nonaccrual status unless they are well-secured and in the process of collection. The remaining loans are evaluated and segmented with loans with similar risk characteristics. The Company allocates reserves based on risk categories and portfolio segments described below, which conform to the Company’s asset classification policy. In reviewing risk within Civista’s loan portfolio, management has identified specific segments to categorize loan portfolio risk: (i) Commercial & Agriculture loans; (ii) Commercial Real Estate – Owner Occupied loans; (iii) Commercial Real Estate – Non-Owner Occupied loans; (iv) Residential Real Estate loans; (v) Real Estate Construction loans; (vi) Farm Real Estate loans; and (vii) Consumer and Other loans. Additional information related to economic factors can be found in Note 5. Loan Charge-off Policies: NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Troubled Debt Restructurings: Other Real Estate: Premises and Equipment: Federal Home Loan Bank Stock a b c d Federal Reserve Bank Stock Bank Owned Life Insurance (BOLI) Goodwill and Other Intangible Assets: NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Other intangible assets consist of core deposit intangibles arising from whole bank and branch acquisitions. These intangible assets are measured at fair value and then amortized on an accelerated method over their estimated useful lives, which range from five to twelve years. Servicing Rights Long-term Assets: Repurchase Agreements Loan Commitments and Related Financial Instruments: Income Taxes The Company prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. Stock-Based Compensation NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. Retirement Plans Earnings per Common Share Comprehensive Income Loss Contingencies Restrictions on Cash Dividend Restriction Fair Value of Financial Instruments Operating Segments Business Combinations: NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Derivative Instruments and Hedging Activities Derivatives and Hedging Reclassifications: Change in Accounting Principal: In January 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities The Company adopted ASU 2016-01 during the reporting period. The adoption resulted in the Company recognizing a one-time cumulative effect adjustment of $278 on January 1, 2018 between accumulated other comprehensive loss and retained earnings on the consolidated balance sheet for the fair value of the equity securities included in accumulated other comprehensive loss as of the beginning of the period. The adjustment had no impact on net income for any periods presented. On a prospective basis, the Company implemented changes to the measurement of the fair value of financial instruments using an exit price notion for disclosure purposes in Note 17 to the financial statements. The December 31, 2017, fair value of each class of financial instruments disclosure did not utilize the exit price notion when measuring fair value and, therefore, would not be comparable to the December 31, 2018 disclosure. The Company estimated the fair value based on guidance from ASC 820-10, Fair Value Measurements NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) In March 2017, the FASB issued ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” Effect of Newly Issued but Not Yet Effective Accounting Standards: In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20).

Business Combinations [Abstract]
Merger	NOTE 2 – MERGER On September 14, 2018, CBI completed the acquisition by merger of United Community Bancorp (“UCB”) in a stock and cash transaction for aggregate consideration of approximately $117,344. As a result of the acquisition, the Company issued 4,277,430 common shares and paid approximately $12,675 in cash to the former shareholders of UCB. The Company and UCB had first announced that they had entered into an agreement to merge in March of 2018. At the time of the merger, UCB had total assets of $537,875, including $298,319 in loans, and $475,944 in deposits. The transaction was recorded as a purchase and, accordingly, the operating results of UCB have been included in the Company’s Consolidated Financial Statements since the close of business on September 14, 2018. As of December 31, 2018, the estimated future amortization expense for the core deposit intangible is as follows: Core deposit intangibles 2019 $ 857 2020 842 2021 823 2022 800 2023 773 Thereafter 3,168 $ 7,263 The following table presents financial information for the former UCB included in the Consolidated Statements of Operations from the date of acquisition through December 31, 2018.

This table has been prepared for comparative purposes only and is not indicative of the actual results that would have been attained had the acquisition occurred as of the beginning of the periods presented, nor is it indicative of future results. Pro Formas (unaudited) Twelve months ended December 31, 2018 2017 2016 Net interest income after provision for loan losses $ 74,642 $ 70,100 $ 65,878 Noninterest income 18,331 20,782 20,937 Net income 18,984 19,284 12,914 Pro forma earnings per share: Basic $ 1.51 $ 1.82 $ 1.42 Diluted $ 1.37 $ 1.56 $ 1.18 NOTE 2 – MERGER (Continued) The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition for UCB. Core deposit intangibles will be amortized over a period of ten years using an accelerated method. Goodwill will not be amortized, but instead will be evaluated for impairment. Furthermore, the unaudited pro forma information does not reflect management’s estimate of any revenue-enhancing opportunities nor anticipated cost savings as a result of the integration and consolidation of the acquisition. Merger and acquisition integration costs and amortization of fair value adjustments net of the related income tax effects are included in the amounts below.

Management made certain estimates and exercised judgment in accounting for the acquisition. The following is a description of the methods used to determine fair value of significant assets and liabilities at the acquisition date: Cash: Loans: Deposits: This acquisition provided the Company with the strategic opportunity to expand into new markets that, while similar to existing markets, are projected to be more vibrant in population growth and business opportunity growth. Additionally, the acquisition will provide exposure to suburbs of larger urban areas without the commitment of operating inside large metropolitan areas dominated by regional and national financial organizations. The acquisition also creates synergies on the operational side of the Company by allowing noninterest expenses to be spread over a larger operating base.

An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. Unrealized losses that are determined to be temporary in nature are recorded, net of tax, in accumulated other comprehensive loss on the Consolidated Balance Sheet. The Company has assessed each available-for-sale security position for credit impairment. Factors considered in determining whether a loss is temporary include: • The length of time and the extent to which fair value has been below cost; • The severity of impairment; • The cause of the impairment and the financial condition and near-term prospects of the issuer; • If the Company intends to sell the investment; • If it’s more-likely-than-not the Company will be required to sell the investment before recovering its amortized cost basis; and • If the Company does not expect to recover the investment’s entire amortized cost basis (even if the Company does not intend to sell the investment). NOTE 3 – SECURITIES (Continued) The Company’s review for impairment generally entails: • Identification and evaluation of investments that have indications of impairment; • Analysis of individual investments that have fair values less than amortized cost, including consideration of length of time each investment has been in unrealized loss position and the expected recovery period; • Evaluation of factors or triggers that could cause individual investments to qualify as having other-than-temporary impairment; and • Documentation of these analyses, as required by policy. At December 31, 2018, the Company owned 130 securities that were considered temporarily impaired. The unrealized losses on these securities have not been recognized into income because the issuers’ bonds are of high credit quality, management has the intent and ability to hold these securities for the foreseeable future, and the decline in fair value is largely due to changes in market interest rates. The Company also considers sector specific credit rating changes in its analysis. The fair value is expected to recover as the securities approach their maturity date or reset date. The Company does not intend to sell until recovery and does not believe selling will be required before recovery. The following table presents the net gains and losses on equity investments recognized in earnings at year-end 2018, and the portion of unrealized gains and losses for the period that relates to equity investments held at year-end 2018: 2018 Net gains recognized on equity securities during the year $ 26 Less: Net gains (losses) realized on the sale of equity securities during the period — Unrealized gains recognized in equity securities held at December 31 $ 26

Text Block [Abstract]
Allowance for Loan Losses	NOTE 5 - ALLOWANCE FOR LOAN LOSSES Management has an established methodology to determine the adequacy of the allowance for loan losses that assesses the risks and losses inherent in the loan portfolio. For purposes of determining the allowance for loan losses, the Company has segmented certain loans in the portfolio by product type. Loans are segmented into the following pools: Commercial and Agriculture loans, Commercial Real Estate – Owner Occupied loans, Commercial Real Estate – Non-owner Occupied loans, Residential Real Estate loans, Real Estate Construction loans, Farm Real Estate loans and Consumer and Other loans. Loss migration rates for each risk category are calculated and used as the basis for calculating loan loss allowance allocations. Loss migration rates are calculated over a three-year period for all portfolio segments. Management also considers certain economic factors for trends that management uses to account for the qualitative and environmental changes in risk, which affects the level of the reserve. The following economic factors are analyzed: • Changes in lending policies and procedures • Changes in experience and depth of lending and management staff • Changes in quality of credit review system • Changes in the nature and volume of the loan portfolio • Changes in past due, classified and nonaccrual loans and TDRs • Changes in economic and business conditions • Changes in competition or legal and regulatory requirements • Changes in concentrations within the loan portfolio • Changes in the underlying collateral for collateral dependent loans The total allowance reflects management’s estimate of loan losses inherent in the loan portfolio at the consolidated balance sheet date. The Company considers the allowance for loan losses of $13,679 adequate to cover loan losses inherent in the loan portfolio, at December 31, 2018. The following tables present, by portfolio segment, the changes in the allowance for loan losses, the ending allocation of the allowance for loan losses and the loan balances outstanding for the years ended December 31, 2018, 2017 and 2016. The changes can be impacted by overall loan volume, adversely graded loans, historical charge-offs and economic factors.

The result was represented as an increase in the provision. The allowance for Commercial Real Estate – Owner Occupied loans was reduced by a decrease in general reserves as a result of lower loss rates. The result was represented as a decrease in the provision. The allowance for Commercial Real Estate – Non-Owner Occupied loans increased due to an increase in general reserves required for this type as a result of higher loan balances. The allowance for Residential Real Estate loans was reduced by a decrease in general reserves required for this type as a result of a decrease in loss rates, represented by a decrease in the provision. The allowance for Real Estate Construction loans increased due to higher outstanding loan balances for this type of loan. The allowance for Farm Real Estate loans was reduced by a decrease in general reserves required for this type as a result of lower outstanding loan balances. The result was represented as a decrease in the provision. Management feels that the unallocated amount is appropriate and within the relevant range for the allowance that is reflective of the risk in the portfolio.

The result was represented as a decrease in the provision. The allowance for Commercial Real Estate – Owner Occupied loans was reduced by a decrease in general reserves and charge-offs. The allowance for Commercial Real Estate – Non-Owner Occupied loans increased due to an increase in general reserves required for this type as a result of higher loan balances.

The result was represented as an increase in the provision. The allowance for Commercial Real Estate – Owner Occupied loans was reduced not only by a decrease in specific reserves required for this type, but also by a decrease in general reserves due to decreases in classified, non-accrual loans and lower loss rates for this type. The result of these changes was represented as a decrease in the provision. The decrease in allowance for Commercial Real Estate – Non-Owner Occupied loans was the result of a decrease in general reserves required as a result of lower loss rates and improvement in past due, classified and non-accrual loans for this type. In addition, a payoff on a previously charged down loan was received resulting in a recovery of approximately $1,303. The net result was represented as a decrease in the provision. The allowance for Residential Real Estate loans was reduced by a decrease in general reserves required for this type as a result of a decrease in loss rates, represented by a decrease in the provision. The allowance for Real Estate Construction loans increased due to an increase in loss rates for this type of loan, which was represented as an increase in the provision.

The remaining loans in the Residential Real Estate, Real Estate Construction and Consumer and Other loan categories that are not assigned a risk grade are presented in a separate table below. The risk rating analysis estimates the capability of the borrower to repay the contractual obligations of the loan agreements as scheduled or at all. The Company’s internal credit risk rating system is based on experiences with similarly graded loans. The Company’s internally assigned grades are as follows: • Pass – loans which are protected by the current net worth and paying capacity of the obligor or by the value of the underlying collateral. • Special Mention – loans where a potential weakness or risk exists, which could cause a more serious problem if not corrected. • Substandard – loans that have a well-defined weakness based on objective evidence and are characterized by the distinct possibility that Civista will sustain some loss if the deficiencies are not corrected. • Doubtful – loans classified as doubtful have all the weaknesses inherent in a substandard asset. In addition, these weaknesses make collection or liquidation in full highly questionable and improbable, based on existing circumstances. • Loss – loans classified as a loss are considered uncollectible, or of such value that continuance as an asset is not warranted. • Unrated – Generally, Residential Real Estate, Real Estate Construction and Consumer and Other loans are not risk-graded, except when collateral is used for a business purpose.

The types of loans presented here are not assigned a risk grade unless there is evidence of a problem. Payment activity is reviewed by management on a monthly basis to evaluate performance. Loans are considered to be nonperforming when they become 90 days past due or if management thinks that we may not collect all of our principal and interest. Nonperforming loans also include certain loans that have been modified in Troubled Debt Restructurings (TDRs) where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties. These concessions typically result from the Company’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions due to economic status. Certain TDRs are classified as nonperforming at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months.

As a result, loans modified in a TDR may have the financial effect of increasing the specific allowance associated with the loan. An allowance for impaired loans that have been modified in a TDR are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or the estimated fair value of the collateral, less any selling costs, if the loan is collateral dependent. Management exercises significant judgment in developing these estimates. TDRs accounted for $143 of the allowance for loan losses as of December 31, 2018, $169 as of December 31, 2017 and $278 as of December 31, 2016. Loan modifications that are considered TDRs completed during the twelve month periods ended December 31, 2018, 2017 and 2016 were as follows: For the Twelve Month Period Ended December 31, 2018 Number of Contracts Pre- Modification Outstanding Recorded Investment Post- Modification Outstanding Recorded Investment Commercial & Agriculture — $ — $ — Commercial Real Estate: Owner Occupied — — — Non-Owner Occupied — — — Residential Real Estate 1 23 23 Real Estate Construction — — — Farm Real Estate 1 110 110 Consumer and Other — — — Total Loan Modifications 2 $ 133 $ 133 NOTE 5 - ALLOWANCE FOR LOAN LOSSES (Continued) For the Twelve Month Period Ended December 31, 2017 Number of Contracts Pre- Modification Outstanding Recorded Investment Post- Modification Outstanding Recorded Investment Commercial & Agriculture — $ — $ — Commercial Real Estate: Owner Occupied — — — Non-Owner Occupied — — — Residential Real Estate 1 13 13 Real Estate Construction — — — Farm Real Estate — — — Consumer and Other — — — Total Loan Modifications 1 $ 13 $ 13 For the Twelve Month Period Ended December 31, 2016 Number of Contracts Pre- Modification Outstanding Recorded Investment Post- Modification Outstanding Recorded Investment Commercial & Agriculture 4 $ 529 $ 529 Commercial Real Estate: Owner Occupied — — — Non-Owner Occupied — — — Residential Real Estate 2 308 308 Real Estate Construction — — — Farm Real Estate 3 700 700 Consumer and Other — — — Total Loan Modifications 9 $ 1,537 $ 1,537 Recidivism, or the borrower defaulting on its obligation pursuant to a modified loan, results in the loan once again becoming a non-accrual loan. Recidivism occurs at a notably higher rate than do defaults on new originations loans, so modified loans present a higher risk of loss than do new origination loans. During the periods ended December 31, 2018, 2017 and 2016, there were no defaults on loans that were modified and considered TDRs during the previous twelve months.

Subordinated Debentures	NOTE 13 - SUBORDINATED DEBENTURES Trusts formed by the Company issued floating rate trust preferred securities, in the amounts of $5,000 and $7,500, through special purpose entities as part of pooled offerings of such securities. The Company issued subordinated debentures to the trusts in exchange for the proceeds of the offerings, which debentures represent the sole assets of the trusts. The Company may redeem the subordinated debentures, in whole but not in part, at face value. In April 2007, the Company elected to redeem and refinance the $5,000 floating rate subordinated debenture. The refinancing was done at face value and resulted in a 2.00% reduction in the floating rate. The new subordinated debenture has a 30-year maturity and is redeemable, in whole or in part, anytime without penalty. The replacement subordinated debenture does not have any deferred issuance cost associated with it. The interest rate at December 31, 2018 on the $7,500 debenture was 5.52% and the $5,000 debenture was 3.93%. Additionally, the Company formed an additional trust that issued $12,500 of 6.05% fixed rate trust preferred securities for five years, then becoming floating rate trust preferred securities, through a special purpose entity as part of a pooled offering of such securities. The Company issued subordinated debentures to the trusts in exchange for the proceeds of the offerings, which debentures represent the sole assets of the trusts. The Company may redeem the subordinated debentures at face value without penalty. The current rate on the $12,500 subordinated debenture is 4.59%. NOTE 13 - SUBORDINATED DEBENTURES (Continued) Finally, the Company acquired two additional trust preferred securities as part of its acquisition of Futura Banc Corp (Futura) in December 2007. Futura TPF Trust I and Futura TPF Trust II were formed in June of 2005 in the amounts of $2,500 and $1,927, respectively. Futura had issued subordinated debentures to the trusts in exchange for ownership of all of the common security of the trusts and the proceeds of the preferred securities sold by the trusts. The Company may redeem the subordinated debentures, in whole or in part, in a principal amount with integral multiples of $1,000, at 100% of the principal amount, plus accrued and unpaid interest. The subordinated debentures mature on June 15, 2035. The subordinated debentures are also redeemable in whole or in part from time to time, upon the occurrence of specific events defined within the trust indenture. The current rate on the $2,500 subordinated debenture is variable at 3.99%. In June 2010, the rate on the $1,927 subordinated debenture switched from a fixed rate to a floating rate. The current rate on the $1,927 subordinated debenture is 3.99%.

As a result, the carrying value of net deferred tax assets was reduced, which increased income tax expense by $511 for the year ended December 31, 2017. NOTE 14 - INCOME TAXES (Continued) Year-end deferred tax assets and liabilities were due to the following: 2018 2017 Deferred tax assets Allowance for loan losses $ 3,056 $ 2,848 Deferred compensation 1,217 1,213 Intangible assets 475 95 Purchase accounting adjustments 566 — Net operating loss carryforward 1,374 — Other 364 141 Deferred tax asset 7,052 4,297 Deferred tax liabilities Tax depreciation in excess of book depreciation (556 ) (275 ) Discount accretion on securities (31 ) (43 ) Purchase accounting adjustments — (536 ) FHLB stock dividends (1,053 ) (1,053 ) Unrealized gain on securities available for sale (624 ) (847 ) Pension costs (469 ) (293 ) Prepaids (301 ) (320 ) BOLI (337 ) — Other (271 ) (166 ) Deferred tax liability (3,642 ) (3,533 ) Net deferred tax asset $ 3,410 $ 764 No valuation allowance was established at December 31, 2018 and 2017, due to the Company’s ability to carryback to taxes paid in previous years and certain tax strategies, coupled with the anticipated future income as evidenced by the Company’s earning potential. The Company and its subsidiaries are subject to U.S. federal income tax. The Company is subject to tax in Ohio based upon its net worth and in Indiana based upon its net income. There is currently no liability for uncertain tax positions and no known unrecognized tax benefits. The Company’s federal tax returns for taxable years through 2012 have been closed for purposes of examination by the Internal Revenue Service.

Compensation And Retirement Disclosure [Abstract]
Retirement Plans	NOTE 15 - RETIREMENT PLANS The Company sponsors a savings and retirement 401(k) plan, which covers all employees who meet certain eligibility requirements and who choose to participate in the plan. The matching contribution to the 401(k) plan was $892, $805 and $734 in 2018, 2017 and 2016, respectively. The Company’s matching contribution is 100% of an employee’s first three percent contributed and 50% of the next two percent contributed. The Company also sponsors a pension plan which is a noncontributory defined benefit retirement plan for all employees who have attained the age of 20 1 ⁄ 2, completed six months of service and work 1,000 or more hours per year. Annual payments, subject to the maximum amount deductible for federal income tax purposes, are made to a pension trust fund. In 2006, the Company amended the pension plan to provide that no employee could be added as a participant to the pension plan after December 31, 2006. In April 2014, the Company amended the pension plan again to provide that no additional benefits would accrue beyond April 30, 2014. NOTE 15 - RETIREMENT PLANS (Continued) In October 2015, the Company, on behalf of it and its subsidiaries, entered into Pension Shortfall Agreements (the “Shortfall Agreements”) with ten employees of the Bank. When the Company ceased accruals to its defined benefit pension plan on April 30, 2014, the circumstances of some participants with limited periods until their anticipated retirement dates would not permit them to use other available alternatives to make up for the shortfall in their expected pension. The Company calculated the total amount of the shortfall for each of the referenced individuals after considering its contributions to other retirement benefits. Pension shortfall expense was $180 in 2018, $18 in 2017 and $201 in 2016. Included in pension shortfall expense was interest expense, totaling $24, $18 and $11 in 2018, 2017 and 2016, respectively, which was also recorded in and credited to the accounts of the ten individuals covered by this plan. Information about the pension plan is as follows: 2018 2017 Change in benefit obligation: Beginning benefit obligation $ 17,916 $ 16,964 Service cost — — Interest cost 627 679 Curtailment gain — — Settlement loss 98 46 Actuarial (gain)/loss (1,800 ) 986 Benefits paid (104 ) (91 ) Settlement payments (3,399 ) (668 ) Ending benefit obligation 13,338 17,916 Change in plan assets, at fair value: Beginning plan assets 19,306 16,150 Actual return (207 ) 1,947 Employer contribution — 2,000 Benefits paid (104 ) (91 ) Settlement payments (3,399 ) (668 ) Administrative expenses (24 ) (32 ) Ending plan assets 15,572 19,306 Funded status at end of year $ 2,234 $ 1,390 Amounts recognized in accumulated other comprehensive loss at December 31, consist of unrecognized actuarial loss of $3,799, net of $1,010 tax in 2018 and $4,070, net of $2,191 tax in 2017. The accumulated benefit obligation for the defined benefit pension plan was $13,338 at December 31, 2018 and $17,916 at December 31, 2017. NOTE 15 - RETIREMENT PLANS (Continued) The components of net periodic pension expense were as follows: 2018 2017 2016 Service cost $ — $ — $ — Interest cost 627 679 689 Expected return on plan assets (1,355 ) (1,178 ) (1,090 ) Net amortization and deferral 149 380 326 Net periodic pension cost (benefit) (579 ) (119 ) (75 ) Additional loss due to settlement 1,188 237 259 Total pension cost (benefit) $ 609 $ 118 $ 184 Net loss (gain) recognized in other comprehensive loss $ (1,453 ) $ (322 ) $ 448 Total recognized in net periodic benefit cost and other comprehensive loss (before tax) $ (2,032 ) $ (441 ) $ 373 The components of net periodic benefit cost other than the service cost component are included in the line item “other operating expenses” in the Consolidated Statement of Operations. The estimated net loss for the defined benefit pension plan that will be amortized from accumulated other comprehensive loss into net periodic benefit cost over the next fiscal year is $149. The Company incurred settlement costs in 2018, 2017 and 2016 of $1,188, $237 and $259, respectively. The weighted average assumptions used to determine benefit obligations at year-end were as follows: 2018 2017 2016 Discount rate on benefit obligation 4.14 % 3.51 % 4.00 % Long-term rate of return on plan assets 7.00 % 7.00 % 7.00 % Rate of compensation increase 0.00 % 0.00 % 0.00 % The weighted average assumptions used to determine net periodic pension cost were as follows: 2018 2017 2016 Discount rate on benefit obligation 3.51 % 4.00 % 4.16 % Long-term rate of return on plan assets 7.00 % 7.00 % 7.00 % Rate of compensation increase 0.00 % 0.00 % 0.00 % The Company uses long-term market rates to determine the discount rate on the benefit obligation. Declines in the discount rate lead to increases in the actuarial loss related to the benefit obligation. The expectation for long-term rate of return on the pension assets and the expected rate of compensation increases are reviewed periodically by management in consultation with outside actuaries and primary investment consultants. Factors considered in setting and adjusting these rates are historic and projected rates of return on the portfolio and historic and estimated rates of increases of compensation. Since the pension plan is frozen, the rate of compensation increase used to determine the benefit obligation for 2018, 2017 and 2016 was zero. NOTE 15 - RETIREMENT PLANS (Continued) The Company’s pension plan asset allocation at year-end 2018 and 2017 and target allocation for 2019 by asset category are as follows: Target Allocation Percentage of Plan Assets at Year-end Asset Category 2019 2018 2017 Equity securities 20-50% 33.1 % 48.0 % Debt securities 30-60 20.7 51.9 Money market funds 20-30 46.2 0.1 Total 100.0 % 100.0 % The Company developed the pension plan investment policies and strategies for plan assets with its pension management firm. The assets are currently invested in four diversified investment funds, which include two equity funds, one money market fund and one bond fund. The long-term guidelines from above were created to maximize the return on portfolio assets while reducing the risk of the portfolio. The management firm may allocate assets among the separate accounts within the established long-term guidelines. Transfers among these accounts will be at the management firm’s discretion based on their investment outlook and the investment strategies that are outlined at periodic meetings with the Company. Actual allocations vary from target allocations as management elected to reclassify approximately $2.7 million into money market funds as short-term strategy pending further reallocation. The expected long-term rate of return on the plan assets was 7.00% in 2018 and 2017. This return is based on the expected return for each of the asset categories, weighted based on the target allocation for each class. The Company does not expect to make any contribution to its pension plan in 2019. Employer contributions totaled $0 in 2018. Increased plan assets offset by increased benefit obligations and actuarial gains led to a change in funded status from $1,390 at December 31, 2017 to $2,234 at December 31, 2018. The following tables set forth by level, within the fair value hierarchy, the pension plan’s assets at fair value as of December 31, 2018 and 2017: December 31, 2018 Level 1 Level 2 Level 3 Total Assets: Money market funds $ 2,689 $ — $ — $ 2,689 Bond mutual funds — — — — Common/collective trust: Bonds 3,221 — — 3,221 Equities 5,153 — — 5,153 Money market 4,509 — — 4,509 Equity market funds: International — — — — Large cap — — — — Mid cap — — — — Small cap — — — — Total assets at fair value $ 15,572 $ — $ — $ 15,572 NOTE 15 - RETIREMENT PLANS (Continued) December 31, 2017 Level 1 Level 2 Level 3 Total Assets: Cash $ 113 $ — $ — $ 113 Bond mutual funds 23 — — 23 Common/collective trust: Bonds 9,980 — — 9,980 Equities 6,654 — — 6,654 Equity market funds: International 750 — — 750 Large cap 1,085 — — 1,085 Mid cap 269 — — 269 Small cap 432 — — 432 Total assets at fair value $ 19,306 $ — $ — $ 19,306 Investment in equity securities, debt securities, money market funds and mutual funds are valued at the closing price reported on the active market on which the individual securities are traded. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Pension Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. Expected benefit payments, which reflect expected future service, are as follows: 2019 $ 2,332 2020 330 2021 781 2022 1,734 2023 757 2024 through 2028 4,928 Total $ 10,862 Supplemental Retirement Plan Civista established a supplemental retirement plan (“SERP”) in 2013, which covers key members of management. Under the SERP, participants will receive annually, following retirement, a percentage of their base compensations at the time of their retirement for a maximum of ten years. The SERP liability recorded at December 31, 2018, was $2,570, compared to $2,308 at December 31, 2017. The expense related to the SERP was $351, $365 and $243 for 2018, 2017 and 2016, respectively. Distributions to participants made in 2018, 2017 and 2016 totaled $87, $41, and $34, respectively.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Equity Incentive Plan	NOTE 16 - EQUITY INCENTIVE PLAN At the Company’s 2014 annual meeting, the shareholders adopted the Company’s 2014 Incentive Plan (“2014 Incentive Plan”). The 2014 Incentive Plan authorizes the Company to grant options, stock awards, stock units and other awards for up to 375,000 common shares of the Company. There were 269,168 shares available for grants under this plan at December 31, 2018. No options had been granted under the 2014 Incentive Plan as of December 31, 2018 and 2017 During each of the last two years, the Board of Directors has awarded restricted common shares to senior officers of the Company. The restricted shares vest ratably over a three-year period following the grant date. The product of the number of restricted shares granted and the grant date market price of the Company’s common shares determines the fair value of restricted shares under the Company’s 2014 Incentive Plan. Management recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite service period for the entire award. On January 4, 2016, directors of the Company’s banking subsidiary, Civista, were paid a retainer in the form of non-restricted common shares of the Company. The aggregate of 2,730 common shares were issued to Civista directors as payment of their retainer for their service on the Civista Board of Directors covering the period up to the 2016 Annual Meeting.

Fair Value Disclosures [Abstract]
Fair Value Measurement	NOTE 17 - FAIR VALUE MEASUREMENT U.S. generally accepted accounting principles establish a hierarchal disclosure framework associated with the level of observable pricing utilized in measuring assets and liabilities at fair value. The three broad levels defined by the hierarchy are as follows: Level 1: Quoted prices for identical assets in active markets that are identifiable on the measurement date; Level 2: Significant other observable inputs, such as quoted prices for similar assets, quoted prices in markets that are not active and other inputs that are observable or can be corroborated by observable market data; Level 3: Significant unobservable inputs that reflect the Company’s own view about the assumptions that market participants would use in pricing an asset. Securities: NOTE 17 - FAIR VALUE MEASUREMENT (Continued) Equity securities: Fair value swap asset/liability: Impaired loans: Other real estate owned: Assets and liabilities measured at fair value are summarized below.

Fair value for other securities approximates carrying value. For fixed rate loans or deposits and for variable rate loans or deposits with infrequent repricing or repricing limits, fair value is based on discounted cash flows using current market rates applied to the cash flow analysis or underlying collateral values. For swaps, fair value of the swap asset and liability is based on an external derivative model using data inputs as of the valuation date. Fair value of debt is based on current rates for similar financing. The fair value of off-balance-sheet items is based on the current fees or cost that would be charged to enter into or terminate such arrangements and are considered nominal. NOTE 17 - FAIR VALUE MEASUREMENT (Continued) For certain homogeneous categories of loans, such as some residential mortgages, credit card receivables, and other consumer loans, fair value is estimated using the quoted market prices for securities backed by similar loans, adjusted for differences in loan characteristics. The fair value of other types of loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Commitments And Contingencies Disclosure [Abstract]
Commitments, Contingencies and Off-Balance-Sheet Risk	NOTE 18 - COMMITMENTS, CONTINGENCIES AND OFF-BALANCE-SHEET RISK Some financial instruments, such as loan commitments, credit lines, letters of credit, and overdraft protection are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off-balance-sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of the commitment. The contractual amount of financial instruments with off-balance-sheet risk was as follows at year-end. 2018 2017 Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to extend credit: Lines of credit and construction loans $ 14,984 $ 359,220 $ 4,982 $ 286,925 Overdraft protection 3 37,201 7 33,353 Letters of credit 624 850 624 2,637 $ 15,611 $ 397,271 $ 5,613 $ 322,915 Commitments to make loans are generally made for a period of one year or less.

Capital Requirements And Restriction On Retained Earnings [Abstract]
Capital Requirements and Restriction on Retained Earnings	NOTE 19 - CAPITAL REQUIREMENTS AND RESTRICTION ON RETAINED EARNINGS CBI and Civista are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory-and possibly additional discretionary-actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Companies must meet specific capital guidelines that involve quantitative measures of the Companies’ assets, liabilities, and certain off-balance-sheet items as calculated under U.S. GAAP, regulatory reporting requirements, and regulatory capital standards. The Companies’ capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulatory capital standards to ensure capital adequacy require the Companies to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital to risk-weighted assets, common equity Tier 1 capital to total risk-weighted assets, and of Tier 1 capital to average assets. Management believes, as of December 31, 2018, that the Companies met all capital adequacy requirements to which they were subject. NOTE 19 - CAPITAL REQUIREMENTS AND RESTRICTION ON RETAINED EARNINGS (Continued) As of December 31, 2018, and 2017, the most recent notification from the Federal Reserve Bank categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Companies must maintain minimum total risk-based capital, Tier 1 risk-based capital, common equity Tier 1 risk-based capital, and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the institution’s category. The Company’s and Civista’s actual capital levels and minimum required capital levels at December 31, 2018 and 2017 were as follows: To Be Well Capitalized Under For Capital Prompt Corrective Actual Adequacy Purposes Action Purposes Amount Ratio Amount Ratio Amount Ratio 2018 Total Risk Based Capital Consolidated $ 260,531 16.1 % $ 129,080 8.0 % n/a n/a Civista 228,620 14.2 128,918 8.0 $ 161,407 10.0 % Tier I Risk Based Capital Consolidated 246,852 15.3 96,810 6.0 n/a n/a Civista 213,922 13.3 96,689 6.0 129,125 8.0 CET1 Risk Based Capital Consolidated 208,061 12.9 72,608 4.5 n/a n/a Civista 203,441 12.6 72,517 4.5 104,914 6.5 Leverage Consolidated 246,852 12.8 80,788 4.0 n/a n/a Civista 213,922 10.6 80,642 4.0 100,802 5.0 2017 Total Risk Based Capital Consolidated $ 200,772 16.6 % $ 97,025 8.0 % n/a n/a Civista 161,394 13.3 96,880 8.0 $ 121,100 10.0 % Tier I Risk Based Capital Consolidated 187,638 15.5 72,769 6.0 n/a n/a Civista 147,473 12.2 72,660 6.0 96,880 8.0 CET1 Risk Based Capital Consolidated 140,853 11.6 54,576 4.5 n/a n/a Civista 136,760 11.3 54,495 4.5 78,715 6.5 Leverage Consolidated 187,638 12.7 59,089 4.0 n/a n/a Civista 147,473 10.0 59,031 4.0 73,788 5.0 CBI’s primary source of funds for paying dividends to its shareholders and for operating expense is the cash accumulated from dividends received from Civista. Payment of dividends by Civista to CBI is subject to restrictions by Civista’s regulatory agencies. These restrictions generally limit dividends to the current and prior two years retained earnings as defined by the regulations. In addition, dividends may not reduce capital levels below minimum regulatory requirements. At December 31, 2018, Civista had $50,821 of net profits available to pay dividends to CBI without requiring regulatory approval.

Derivative Hedging Instruments	NOTE 24 - DERIVATIVE HEDGING INSTRUMENTS To accommodate customer need and to support the Company’s asset/liability positioning, on occasion we enter into interest rate swaps with a customer and a bank counterparty. The Company enters into a floating rate loan and a fixed rate swap with our customer. Simultaneously, the Company enters into an offsetting fixed rate swap with a bank counterparty. In connection with each swap transaction, the Company agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on the same notional amount at a fixed interest rate. At the same time, the Company agrees to pay a bank counterparty the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. These transactions allow the Company’s customer to effectively convert variable rate loans to fixed rate loans. Since the Company acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts offset each other and do not significantly impact the Company’s results of operations.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	NOTE 26 – REVENUE RECOGNITION On January 1, 2018, the Company adopted ASU No. 2014-09 “Revenue from Contracts with Customers” (Topic 606) Significant Accounting Policies Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as trust and asset management income, deposit related fees, interchange fees, merchant income, and annuity and insurance commissions. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest revenue streams in-scope of Topic 606 are discussed below. Service Charges Service charges consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. ATM/Interchange Fees Fees, exchange, and other service charges are primarily comprised of debit and credit card income, ATM fees and other service charges. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as Mastercard. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. The Company’s performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month. Wealth Management Fees Wealth management fees are primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received in the following month through a direct charge to customers’ accounts. The Company does not earn performance-based incentives. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered. Tax Refund Processing Fees The Company facilitates the payment of federal and state income tax refunds in partnership with a third-party vendor. Refund Transfers (“RTs”) are fee-based products whereby a tax refund is issued to the taxpayer after the Company has received the refund from the federal or state government. As part of this agreement the Company earns fee income, the majority of which is received in the first quarter of the year. The Company’s fee income revenue is recognized based on the estimated percent of business completed by each date. NOTE 26 – REVENUE RECOGNITION (Continued) Other Other noninterest income consists of other recurring revenue streams such as check order fees, wire transfer fees, safety deposit box rental fees, item processing fees and other miscellaneous revenue streams. Check order income mainly represents fees charged to customers for checks. Wire transfer fees represent revenue from processing wire transfers. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation. Item processing fee income represents fees charged to other financial institutions for processing their transactions. Payment is typically received in the following month. The following presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the years ended December 31, 2018, 2017 and 2016. For the years ended December 31, 2018 2017 2016 Noninterest Income In-scope of Topic 606: Service charges $ 5,208 $ 4,777 $ 4,832 ATM/Interchange fees 2,794 2,304 2,094 Wealth management fees 3,669 3,068 2,678 Tax refund processing fees 2,750 2,750 2,750 Other 892 738 949 Noninterest Income (in-scope of Topic 606) 15,313 13,637 13,303 Noninterest Income (out-of-scope of Topic 606) 2,818 2,697 2,829 Total Noninterest Income $ 18,131 $ 16,334 $ 16,132 Contract Balances A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of December 31, 2018 and December 31, 2017, the Company did not have any significant contract balances. Contract Acquisition Costs In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of Topic 606, the Company did not capitalize any contract acquisition cost. This page left blank intentionally.

Nature of Operations and Principles of Consolidation	Nature of Operations and Principles of Consolidation Civista provides financial services through its offices in the Ohio counties of Erie, Crawford, Champaign, Cuyahoga, Franklin, Logan, Summit, Huron, Ottawa, Madison, Montgomery and Richland, in the Indiana counties of Dearborn and Ripley and in the Kentucky county of Kenton. Its primary deposit products are checking, savings, and term certificate accounts, and its primary lending products are residential mortgage, commercial, and installment loans. Substantially all loans are secured by specific items of collateral including business assets, consumer assets and commercial and residential real estate. Commercial loans are expected to be repaid from cash flow from operations of businesses. There are no significant concentrations of loans to any one industry or customer. However, our customers’ ability to repay their loans is dependent on the real estate and general economic conditions in the area. Other financial instruments that potentially represent concentrations of credit risk include deposit accounts in other financial institutions. FCIA was formed to allow the Company to participate in commission revenue generated through its third party insurance agreement. Insurance commission revenue was less than 1.0% of total revenue for the years ended December 31, 2018, 2017 and 2016. WSP was formed to hold repossessed assets of CBI’s subsidiaries. WSP revenue was less than 1% of total revenue for the years ended December 31, 2018, 2017 and 2016. FCRS was formed in 2012 and remained inactive for the periods presented. CRMI was formed in 2017 to provide property and casualty insurance coverage to CBI and its’ subsidiaries for which insurance may not be currently available or economically feasible in the insurance marketplace. CRMI revenue was less than 1% of total revenue for the years ended December 31, 2018 and 2017.
Use of Estimates	Use of Estimates

Securities	Securities NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) On January 1, 2018, the Company adopted the new accounting standard for Financial Instruments, which requires equity securities to be measured at fair value with the changes in fair value recognized in net income. The adoption of this guidance resulted in a $278 increase in retained earnings and a $278 decrease in to accumulated other comprehensive income. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are based on the amortized cost of the security sold using the specific identification method. Under U.S. generally accepted accounting principles (“GAAP”) guidance, if (a) a company does not have the intent to sell a debt security prior to recovery and (b) it is more-likely-than-not that it will not have to sell the debt security prior to recovery, the security would not be considered other-than-temporarily impaired unless there is a credit loss. When an entity does not intend to sell the security, and it is more-likely-than-not the entity will not have to sell the security before recovery of its cost basis, it will recognize the credit component of other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of other-than-temporary impairment recorded in other comprehensive income for the non-credit portion of a previous other-than-temporary impairment should be amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security. For available-for-sale debt securities that management has no intent to sell and believes that it more-likely-than-not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the non-credit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections. Other securities which include FHLB stock, Federal Reserve Bank (“FRB”) stock, Federal Agricultural Mortgage Corporation stock, Bankers’ Bancshares Inc. (“BB”) stock, and Norwalk Community Development Corp (“NCDC”) stock are carried at cost.
Loans Held for Sale	Loans Held for Sale:
Loans	Loans: Interest income on mortgage and commercial loans is discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection. Interest income on consumer loans is discontinued when management determines future collection is unlikely. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued, but not received, for loans placed on nonaccrual, is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Purchased Loans	Purchased Loans: Purchased loans are accounted for individually or aggregated into pools of loans based on common risk characteristics (e.g., credit score, loan type, and date of origination). The Company estimates the amount and timing of expected cash flows for each purchased loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield). The excess of the loan’s, or pool’s, contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan or pool, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded. If the present value of expected future cash flows is greater than the carrying amount, the excess is recognized as part of future interest income.
Allowance for Loan Losses	Allowance for Loan Losses: All commercial, commercial real estate and farm real estate loans are monitored on a regular basis with a detailed loan review completed for all loan relationships greater than $750. All commercial, commercial real estate and farm real estate loans that are 90 days past due or in nonaccrual status, are analyzed to determine if they are “impaired”, which means that it is probable that all amounts will not be collected according to the contractual terms of the loan agreement. All loans that are delinquent 90 days are classified as substandard and placed on nonaccrual status unless they are well-secured and in the process of collection. The remaining loans are evaluated and segmented with loans with similar risk characteristics. The Company allocates reserves based on risk categories and portfolio segments described below, which conform to the Company’s asset classification policy. In reviewing risk within Civista’s loan portfolio, management has identified specific segments to categorize loan portfolio risk: (i) Commercial & Agriculture loans; (ii) Commercial Real Estate – Owner Occupied loans; (iii) Commercial Real Estate – Non-Owner Occupied loans; (iv) Residential Real Estate loans; (v) Real Estate Construction loans; (vi) Farm Real Estate loans; and (vii) Consumer and Other loans. Additional information related to economic factors can be found in Note 5.

Income Taxes	Income Taxes The Company prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The Company recognizes interest and/or penalties related to income tax matters in income tax expense.
Stock-Based Compensation	Stock-Based Compensation NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.

Change in Accounting Principal	Change in Accounting Principal: In January 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities The Company adopted ASU 2016-01 during the reporting period. The adoption resulted in the Company recognizing a one-time cumulative effect adjustment of $278 on January 1, 2018 between accumulated other comprehensive loss and retained earnings on the consolidated balance sheet for the fair value of the equity securities included in accumulated other comprehensive loss as of the beginning of the period. The adjustment had no impact on net income for any periods presented. On a prospective basis, the Company implemented changes to the measurement of the fair value of financial instruments using an exit price notion for disclosure purposes in Note 17 to the financial statements. The December 31, 2017, fair value of each class of financial instruments disclosure did not utilize the exit price notion when measuring fair value and, therefore, would not be comparable to the December 31, 2018 disclosure. The Company estimated the fair value based on guidance from ASC 820-10, Fair Value Measurements NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) In March 2017, the FASB issued ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.”
