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 financial statements. Nature of Operations and Principles of Consolidation The Company provides financial services through its offices in the Ohio counties of Erie, Crawford, Champaign, Cuyahoga, Franklin, Logan, Summit, Huron, Ottawa, Madison, Montgomery and Richland. 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, 2015 and 2014. 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, 2015 and 2014. FCRS was formed in 2012 and remained inactive for the periods presented. Use of Estimates Cash Flows Securities 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. The recent guidance specifies that 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, 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. 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 $500. 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: 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: 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 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: Reclassifications: Derivative Instruments and Hedging Activities Derivatives and Hedging Effect of Newly Issued but Not Yet Effective Accounting Standards: In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers In June 2014, the FASB issued ASU 2014-12, Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance Target Could Be Achieved After the Requisite Service Period In November 2014, the FASB issued ASU 2014-16, Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity (a consensus of the FASB Emerging Issues Task Force).

An entity should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance.

For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. For all other entities including not-for-profit entities and employee benefit plans within the scope of Topics 960 through 965 on plan accounting, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. All entities that are not public business entities may adopt the amendments in this Update earlier as of the fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

The Company and TCNB had first announced that they had entered into an agreement to merge in September of 2014. Immediately following the merger, TCNB’s banking subsidiary, The Citizens National Bank of Southwestern Ohio, was merged into CBI’s banking subsidiary, Civista Bank. At the time of the merger, TCNB had total assets of $97,479, including $76,771 in loans, and $86,708 in deposits. The transaction was recorded as a purchase and, accordingly, the operating results of TCNB have been included in the Company’s Consolidated Financial Statements since the close of business on March 6, 2015. The aggregate of the purchase price over the fair value of the net assets acquired of approximately $5,375 was recorded as goodwill and will be evaluated for impairment on an annual basis. Merger related cost were $391 and $236, respectively as of December 31, 2015 and December 31, 2014. These cost were primarily included in salaries, wages and benefits, contracted data processing and professional services on the consolidated statements of operations. The following table presents financial information for the former TCNB included in the Consolidated Statements of Operations from the date of acquisition through December 31, 2015. Actual From (in thousands) Net interest income after provision for loan losses $ 3,155 Noninterest income 138 Net income 1,282 The following table presents unaudited pro forma information for the periods ended December 31, 2015 and 2014 as if the acquisition of TCNB had occurred on January 1, 2014.

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 and short-term investments: 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 provides the Company with additional 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). 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, 2015, the Company owned 50 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.

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, except for the segment consisting of purchased automobile loans which is calculated over a two-year period. The use of a three-year period for loss migration analysis is a change in methodology. The Company began using the three-year period for loss migration during the third quarter of 2015. Previously, a two-year loss migration analysis had been used for the entire loan portfolio. With continued improvement and stability in economic conditions, regulatory guidance recommends a longer look-back period. In addition, Civista made significant changes to consumer and commercial lending policies in the first quarter of 2012. Combined, the stable economy and now seasoned policy changes indicate a three-year period is more reflective of future expectations. 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 Civista’s 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 $14,361 adequate to cover loan losses inherent in the loan portfolio, at December 31, 2015. 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, 2015 and December 31, 2014. The changes can be impacted by overall loan volume, adversely graded loans, historical charge-offs and economic factors. Beginning Charge-offs Recoveries Provision Ending Allowance for loan losses: December 31, 2015 Commercial & Agriculture $ 1,819 $ (190 ) $ 182 $ (333 ) $ 1,478 Commercial Real Estate: Owner Occupied 2,221 (523 ) 187 582 2,467 Non-Owner Occupied 4,334 (81 ) 115 289 4,657 Residential Real Estate 3,747 (1,135 ) 331 1,143 4,086 Real Estate Construction 428 — 5 (62 ) 371 Farm Real Estate 822 — 76 (360 ) 538 Consumer and Other 200 (120 ) 46 256 382 Unallocated 697 — — (315 ) 382 Total $ 14,268 $ (2,049 ) $ 942 $ 1,200 $ 14,361 For the year ended December 31, 2015, the allowance for Commercial and Agriculture loans was reduced due to decreases in specific reserves for impaired loans of $625. The decrease in specific reserves for impaired loans was primarily the result of the resolution of an impaired loan. The Company did not incur losses with this resolution. The result was represented as a decrease in the provision. The increase in the allowance for Commercial Real Estate - Owner Occupied loans was the result of an increase in loss migration rates, which is attributable to the change in the lookback period to a three-year period. The increase in the allowance for Commercial Real Estate – Non–Owner Occupied loans was the result of an increase in loss migration rates, which is attributable to the change in the lookback period to a three-year period. The ending reserve balance for Residential Real Estate loans increased from the end of the previous year due to an increase in loss migration rates, which is attributable to the change in the look-back period to a three-year period. The allowance for Real Estate Construction loans decreased as a result of decreasing loan balances. The allowance for Farm Real Estate loans decreased as a result of decreasing loan balances and loss rates offset by an increase in classified loans. The increase in the allowance for Consumer and other loans increased due to an increase in loss rates, which is attributable to the change in the look-back period. Unallocated reserves declined due to a change in the Company’s lookback period. As described above, the Company changed from a two-year lookback period to a three-year lookback period when calculating all but one segment’s loss migration rates during the third quarter of 2015. The change in methodology is reflected in a decline in the unallocated balance with corresponding increase in allocated balances within the reserve calculation. While loan balances are up, loss rates continue to trend downward, exclusive of the change in methodology, resulting in a lower allowance balance. While criticized loans have increased slightly, we have seen significant improvement in nonperforming loan balances resulting in a decline in specific reserves for impaired loans. 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. Beginning Charge-offs Recoveries Provision Ending Allowance for loan losses: December 31, 2014 Commercial & Agriculture $ 2,838 $ (338 ) $ 251 $ (932 ) $ 1,819 Commercial Real Estate: Owner Occupied 2,931 (1,661 ) 360 591 2,221 Non-Owner Occupied 3,888 (198 ) 50 594 4,334 Residential Real Estate 5,224 (2,449 ) 293 679 3,747 Real Estate Construction 184 — 6 238 428 Farm Real Estate 740 — — 82 822 Consumer and Other 217 (135 ) 61 57 200 Unallocated 506 — — 191 697 Total $ 16,528 $ (4,781 ) $ 1,021 $ 1,500 $ 14,268 For the year ended December 31, 2014, the allowance for Commercial and Agriculture loans was reduced not only by charge-offs, but also due to a decrease in both the loan balances outstanding and the specific reserve required for this type, which was driven by a decrease in the volume of impaired loans and classified loans. The net result of these changes was represented as a decrease in the provision. The decrease in the allowance for Commercial Real Estate - Owner Occupied loans was the result of eleven charge-offs, but also due to a decrease in loan balances outstanding and a decline in nonaccrual loans. The result of these changes was represented as a decrease in the allowance. The increase in the allowance for Commercial Real Estate - Non-Owner Occupied loans was the result of increasing loan balances and increased past-due balances. The allowance for Real Estate Construction loans increased as a result of a significant increase in loan balances. The ending reserve balance for Residential Real Estate loans declined from the end of the previous year due to charge-offs of loans that had a specific reserve previously applied. Additionally, a single relationship resulted in losses of $1,436 related to protecting the Company’s collateral. The net result of the changes was represented as a decrease in the allowance. The allowance for Consumer and Other loans decreased slightly during the year. While loan balances are up, loss rates continue to decrease resulting in the allowance being slightly lower. While we have seen improvement in asset quality, given the uncertainty in the economy, management determined that it was appropriate to maintain unallocated reserves at a slightly higher level at this time. Beginning Charge- Recoveries Provision Ending Allowance for loan losses: December 31, 2013 Commercial & Agriculture $ 2,811 $ (483 ) $ 141 $ 369 $ 2,838 Commercial Real Estate: Owner Occupied 4,565 (989 ) 265 (910 ) 2,931 Non-Owner Occupied 4,942 (815 ) 184 (423 ) 3,888 Residential Real Estate 5,780 (2,800 ) 391 1,853 5,224 Real Estate Construction 349 (136 ) 108 (137 ) 184 Farm Real Estate 632 (107 ) 67 148 740 Consumer and Other 246 (220 ) 80 111 217 Unallocated 417 — — 89 506 Total $ 19,742 $ (5,550 ) $ 1,236 $ 1,100 $ 16,528 For the year ended December 31, 2013, the allowance for Commercial Real Estate loans was reduced not only by charge-offs, but also due to the specific reserve required for impaired loans within this segment. The net result of these changes was represented as a decrease in the provision. The allowance for Real Estate Construction loans was reduced as a result of changes to specific reserves required for impaired loans and a reduction in the historical charge-offs for this segment. The result of these changes was represented as a decrease in the provision. The ending reserve balance for Residential Real Estate loans declined from the end of the previous year due to charge-offs during the period. Since these charged-off loans already had specific reserves assigned to them, we no longer need to carry as large a reserve for this segment. While we have seen improvement in asset quality, given the uncertainty in the economy, management determined that it was appropriate to maintain unallocated reserves at a higher level at this time.

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 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 $286 of the allowance for loan losses for December 31, 2015, $895 as of December 31, 2014 and $750 as of December 31, 2013. Loan modifications that are considered TDRs completed during the twelve month periods ended December 31, 2015, 2014 and 2013 were as follows: For the Twelve Month Period Ended Number Pre- Post- Commercial & Agriculture — $ — $ — Commercial Real Estate: Owner Occupied — — — Non-Owner Occupied — — — Residential Real Estate — — — Real Estate Construction 1 41 41 Farm Real Estate — — — Consumer and Other — — — Total Loan Modifications 1 $ 41 $ 41 For the Twelve Month Period Ended Number Pre- Post- Commercial & Agriculture — $ — $ — Commercial Real Estate: Owner Occupied — — — Non-Owner Occupied — — — Residential Real Estate 9 619 554 Real Estate Construction 1 35 35 Farm Real Estate — — — Consumer and Other — — — Total Loan Modifications 10 $ 654 $ 589 For the Twelve Month Period Ended Number Pre- Post- Commercial & Agriculture — $ — $ — Commercial Real Estate: Owner Occupied 2 547 547 Non-Owner Occupied — — — Residential Real Estate — — — Real Estate Construction — — — Farm Real Estate — — — Consumer and Other — — — Total Loan Modifications 2 $ 547 $ 547 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 twelve month period ended December 31, 2015, there was one default, totaling $107, on loans which were modified and considered TDRs during the previous twelve months. During the period ended December 31, 2014, there were no defaults on loans that were modified and considered TDRs during the previous twelve months.

Goodwill and Intangible Assets	NOTE 8 – GOODWILL AND INTANGIBLE ASSETS The carrying amount of goodwill increased from $21,720 on December 31, 2014 to $27,095 on December 31, 2015. The increase was the result of the goodwill related to the merger with TCNB Financial Corp. of $5,375. Management performs an annual evaluation of goodwill for impairment, or more frequently if events or changes in circumstances indicate that the asset might be impaired. Management performed an evaluation of the Company’s goodwill during the fourth quarter of 2015. In performing its evaluation, management obtained several commonly used financial ratios from pending and completed purchase transactions for banks based in the Midwest. Management used these ratios to determine an implied market value for the Company. The implied market value was then used to determine whether or not additional testing was required. Based on this test, management concluded that the Company’s goodwill was not impaired at December 31, 2015. Acquired intangible assets were as follows as of year end. 2015 2014 Gross Gross Carrying Accumulated Carrying Accumulated Amount Amortization Amount Amortization Core deposit and other intangibles $ 7,697 $ 5,876 $ 6,688 $ 5,165 Aggregate amortization expense was $711, $769 and $846 for 2015, 2014 and 2013, respectively.

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 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, 2015 on the $7,500 debenture was 3.48% and the $5,000 debenture was 1.94%. 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.

In conjunction with freezing the pension plan, as discussed below, the Company changed the matching contribution calculation from twenty-five percent of the first six percent of an employee’s contribution to 100% of an employee’s first three percent contributed and 50% of the next two percent contributed. This change took place on July 1, 2014. 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 In October 2015, the Company, on behalf of it and its subsidiaries, entered into Pension Shortfall Agreements (the “Shortfall Agreements”) with ten other 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 $380 in 2015. A total of $11 of interest expense was also recorded and credited to the accounts of the ten individuals covered by this plan. Information about the pension plan is as follows: 2015 2014 Change in benefit obligation: Beginning benefit obligation $ 16,953 $ 18,456 Service cost — 306 Interest cost 604 639 Curtailment gain — (4,039 ) Settlement loss 117 55 Actuarial (gain)/loss (6 ) 3,007 Benefits paid (1,340 ) (1,471 ) Ending benefit obligation 16,328 16,953 Change in plan assets, at fair value: Beginning plan assets 16,184 15,466 Actual return 129 703 Employer contribution 700 1,515 Benefits paid (1,340 ) (1,471 ) Administrative expenses (26 ) (29 ) Ending plan assets 15,647 16,184 Funded status at end of year $ (681 ) $ (769 ) Amounts recognized in accumulated other comprehensive income at December 31, consist of unrecognized actuarial loss of $4,049, net of $2,086 tax in 2015 and $3,777, net of $1,946 tax in 2014. The accumulated benefit obligation for the defined benefit pension plan was $16,328 at December 31, 2015 and $16,953 at December 31, 2014. The components of net periodic pension expense were as follows: 2015 2014 2013 Service cost $ — $ 306 $ 1,204 Interest cost 604 639 884 Expected return on plan assets (1,088 ) (1,021 ) (965 ) Net amortization and deferral 270 334 698 Net periodic pension cost (benefit) $ (214 ) $ 258 $ 1,821 Net loss (gain) recognized in other comprehensive loss 412 (1,228 ) (4,406 ) Total recognized in net periodic benefit cost and other comprehensive loss (before tax) $ 198 $ (970 ) $ (2,585 ) 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 $332. The weighted average assumptions used to determine benefit obligations at year-end were as follows: 2015 2014 2013 Discount rate on benefit obligation 4.16 % 3.69 % 4.38 % Long-term rate of return on plan assets 7.00 % 7.00 % 7.00 % Rate of compensation increase 0.00 % 0.00 % 3.00 % The weighted average assumptions used to determine net periodic pension cost were as follows: 2015 2014 2013 Discount rate on benefit obligation 3.69 % 4.38 % 3.72 % Long-term rate of return on plan assets 7.00 % 7.00 % 7.00 % Rate of compensation increase 0.00 % 3.00 % 3.00 % 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 2015 was zero. The Company’s pension plan asset allocation at year-end 2015 and 2014 and target allocation for 2016 by asset category are as follows: Percentage of Plan Target Assets Allocation at Year-end Asset Category 2016 2015 2014 Equity securities 20-50 % 48.2 % 46.7 % Debt securities 30-60 47.0 48.3 Money market funds 20-30 4.8 5.0 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. The expected long-term rate of return on the plan assets was 7.00% in 2015 and 2014. This return is based on the expected return for each of the asset categories, weighted based on the target allocation for each class. Although the plan is frozen, the Company expects to make a $500 contribution to its pension plan in 2016. Employer contributions totaled $700 in 2015. The decrease in the benefit obligation, contributions and the increase in plan assets led to a change in funded status from $(769) at December 31, 2014 to $(681) at December 31, 2015. The following tables set forth by level, within the fair value hierarchy, the pension plan’s assets at fair value as of December 31, 2015 and 2014: December 31, 2015 Level 1 Level 2 Level 3 Total Assets: Money market funds $ 94 $ — $ — $ 94 Bond mutual funds 23 — — 23 Common/collective trust: Bonds 7,338 — — 7,338 Equities 6,315 — — 6,315 Equity market funds: International 357 — — 357 Large cap 1,155 — — 1,155 Mid cap 242 — — 242 Small cap 123 — — 123 Total assets at fair value $ 15,647 $ — $ — $ 15,647 December 31, 2014 Level 1 Level 2 Level 3 Total Assets: Cash $ 3 $ — $ — $ 3 Money market funds 91 — — 91 Bond mutual funds 23 — — 23 Common/collective trust: Bonds 7,802 — — 7,802 Equities 6,383 — — 6,383 Equity market funds: Commodity mutual funds 19 — — 19 International 342 — — 342 Large cap 1,150 — — 1,150 Mid cap 253 — — 253 Small cap 118 — — 118 Total assets at fair value $ 16,184 $ — $ — $ 16,184 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: 2016 $ 1,520 2017 1,820 2018 528 2019 1,367 2020 1,033 2021 through 2025 5,565 Total $ 11,833 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, 2015, was $1,775, compared to $1,498 at December 31, 2014. The expense related to the SERP was $299, $398 and $412 for 2015, 2014 and 2013, respectively. Distributions to participants made in 2015 totaled $22. Distributions to participants made in 2014 totaled $11.

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 358,017 shares available for grants under this plan at December 31, 2015. Certain officers were granted an aggregate of 16,983 restricted shares on March 17, 2015. The 2015 restricted shares vest over a 3-year service period, with one third each vesting on January 2 of 2016, 2017 and 2018. 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. The Company classifies share-based compensation for employees with “Salaries, wages and benefits” in the consolidated statements of income. Additionally, generally accepted accounting principles require the Company to report: (1) the expense associated with the grants as an adjustment to operating cash flows, and (2) any benefits of realized tax deductions in excess of previously recognized tax benefits on compensation expense as a financing cash flow. No options had been granted under the 2014 Incentive Plan as of December 31, 2015 and 2014. During the year ended December 31, 2015, the Company recorded $106 of share-based compensation expense for restricted shares granted under the 2014 Incentive Plan. Expected future compensation expense relating to the 16,983 restricted shares at December 31, 2015, is $78 which will be recognized over the remaining vesting period of 2.00 years. The following is a summary of the status of the Company’s restricted shares as of December 31, 2015, and changes therein during the twelve months ended: December 31, 2015 Weighted Number of Average Restricted Grant Date Shares Fair Value Nonvested at beginning of period — $ — Granted 16,983 10.82 Vested — — Forfeited — — Nonvested at December 31, 2015 16,983 10.82

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: Equity securities: Fair value swap asset/liability: Impaired loans: appraisal was completed. Additionally, management makes estimates about expected costs to sell the property which are also included in the net realizable value. If the fair value of the collateral dependent loan is less than the carrying amount of the loan, a specific reserve for the loan is made in the allowance for loan losses or a charge-off is taken to reduce the loan to the fair value of the collateral (less estimated selling costs) and the loan is included in the table above as a Level 3 measurement. Other real estate owned: Assets measured at fair value are summarized below.

Estimated fair value for securities is based on quoted market values for the individual securities or for equivalent securities. 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. 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. 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, 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. 2015 2014 Fixed Variable Fixed Variable Rate Rate Rate Rate Commitments to extend credit: Lines of credit and construction loans $ 9,416 $ 195,732 $ 9,405 $ 160,718 Overdraft protection 5 22,119 4 22,122 Letters of credit 200 750 200 1,007 $ 9,621 $ 218,601 $ 9,609 $ 183,847 Commitments to make loans are generally made for a period of one year or less.

Capital Requirements and Restriction on Retained Earnings	NOTE 19 – CAPITAL REQUIREMENTS AND RESTRICTION ON RETAINED EARNINGS The Company and Civista (“Companies”) 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 Companies’ 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 factor. 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, 2015, that the Companies meet all capital adequacy requirements to which it is subject. As of December 31, 2015, and December 31, 2014, 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. 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 levels at December 31, 2015 and 2014 were as follows: To Be Well Capitalized Under For Capital Prompt Corrective Actual Adequacy Purposes Action Purposes Amount Ratio Amount Ratio Amount Ratio 2015 Total Risk Based Capital Consolidated $ 140,088 14.0 % $ 80,050 8.0 % n/a n/a Civista 126,795 12.7 79,871 8.0 $ 99,839 10.0 % Tier I Risk Based Capital Consolidated 127,519 12.7 60,245 6.0 n/a n/a Civista 113,883 11.4 59,938 6.0 79,918 8.0 CET1 Risk Based Capital Consolidated 75,819 7.6 44,893 4.5 n/a n/a Civista 102,755 10.1 45,782 4.5 66,129 6.5 Leverage Consolidated 127,519 10.0 51,008 4.0 n/a n/a Civista 113,883 8.9 51,183 4.0 63,979 5.0 2014 Total Risk Based Capital Consolidated $ 131,581 14.7 % $ 71,609 8.0 % n/a n/a Civista 111,470 12.5 71,341 8.0 $ 89,176 10.0 % Tier I Risk Based Capital Consolidated 120,334 13.4 35,921 4.0 n/a n/a Civista 100,259 11.2 35,807 4.0 53,710 6.0 CET1 Risk Based Capital Consolidated n/a n/a n/a n/a n/a n/a Civista n/a n/a n/a n/a n/a n/a Leverage Consolidated 120,334 10.3 46,732 4.0 n/a n/a Civista 100,259 8.6 46,632 4.0 58,290 5.0 The Company’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 the Company 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, 2015, Civista had $6,863 net profits available to pay dividends to CBI.

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. The following table summarizes the Company’s interest rate swap positions and the impact of a 1 basis point change in interest rates as of December 31, 2015.

Accounting Policies [Abstract]
Nature of Operations and Principles of Consolidation	Nature of Operations and Principles of Consolidation The Company provides financial services through its offices in the Ohio counties of Erie, Crawford, Champaign, Cuyahoga, Franklin, Logan, Summit, Huron, Ottawa, Madison, Montgomery and Richland. 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, 2015 and 2014. 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, 2015 and 2014. FCRS was formed in 2012 and remained inactive for the periods presented.
Use of Estimates	Use of Estimates
Cash Flows	Cash Flows
Securities	Securities 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. The recent guidance specifies that 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, 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 $500. 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.

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 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.
