Fair Value Disclosures [Text Block]	NOTE 5 - FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. GAAP establishes a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following levels: Level I: Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Level II: Pricing inputs are other than the quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these assets and liabilities includes items for which quoted prices are available but traded less frequently and items that are fair valued using other financial instruments, the parameters of which can be directly observed. Level III: Assets and liabilities that have little to no not two The following tables present the assets measured on a recurring basis on the Consolidated Balance Sheet at their fair value by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The following tables present the assets measured on a nonrecurring basis on the Consolidated Balance Sheet at their fair value by level within the fair value hierarchy. Collateral-dependent impaired loans are carried at fair value if they have been charged down to fair value or if a specific valuation allowance has been established. A new cost basis is established at the time a property is initially recorded in OREO.

On a quarterly basis, the Company performs an assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered other-than-temporary impairment (“OTTI”). A debt security is considered impaired if the fair value is less than its amortized cost basis at the reporting date. The Company assesses whether the unrealized loss is other than temporary. OTTI losses are recognized in earnings when the Company has the intent to sell the debt security or it is more likely than not not An unrealized loss is generally deemed to be other than temporary and a credit loss is deemed to exist if the present value of the expected future cash flows is less than the amortized cost basis of the debt security.

The Company’s primary business activity is with customers located within its local Northeastern Ohio trade area, Geauga County, and contiguous counties. The Company also serves the central Ohio market with offices in Dublin, Sunbury and Westerville, Ohio. Commercial, residential, consumer, and agricultural loans are granted. Although the Company has a diversified loan portfolio, loans outstanding to individuals and businesses are dependent upon the local economic conditions in the Company’s immediate trade area. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are reported at their outstanding unpaid principal balances net of the allowance for loan and lease losses. Interest income is recognized on the accrual method. The accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that collection of interest is doubtful. Interest payments received on nonaccrual loans are applied against the unpaid principal balance until nonaccrual status is restored. Loan origination fees and certain direct loan origination costs are deferred with the net amount amortized over the contractual life of the loan as an adjustment of the related loan’s yield.

The portfolio is segmented into Commercial and Industrial (“C&I”), Real Estate Construction, Real Estate - Mortgage which is further segmented into Residential and Commercial real estate (“CRE”), and Consumer Installment Loans. The C&I loan segment consists of loans made for the purpose of financing the activities of commercial customers. The residential mortgage loan segment consists of loans made for the purpose of financing the activities of residential homeowners. The commercial mortgage loan segment consists of loans made for the purpose of financing the activities of commercial real estate owners and operators. The consumer loan segment consists primarily of installment loans and overdraft lines of credit connected with customer deposit accounts. The increases in the allowance for loan loss for C&I, Residential, CRE, and Consumer Installment loan portfolios were partially offset by a decrease in the allowance for the Real Estate Construction portfolio. Management evaluates individual loans in all of the commercial segments for possible impairment based on guidance established by the Board of Directors. Loans are considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in evaluating impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed.

Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as bankruptcy, repossession, or death, occurs to raise awareness of a possible credit event. The Company’s Commercial Loan Officers are responsible for the timely and accurate risk rating of the loans in their portfolios at origination and on an ongoing basis with the Chief Credit Officer ultimately responsible for accurate and timely risk ratings. The Credit Department performs an annual review of all commercial relationships with loan balances of $500,000 $250,000 $125,000. The primary risk of commercial and industrial loans is the current economic uncertainties. C&I loans are, by nature, secured by less substantial collateral than real estate-secured loans. The primary risk of real estate construction loans is potential delays and disputes during the completion process. The primary risk of residential real estate loans is current economic uncertainties along with the slow recovery in the housing market. The primary risk of commercial real estate loans is loss of income of the owner or occupier of the property and the inability of the market to sustain rent levels. Consumer installment loans historically have experienced higher delinquency rates. Consumer installments are typically secured by less substantial collateral than other types of credits.

An allowance for loan and lease losses (“ALLL”) is maintained to absorb losses from the loan portfolio. The ALLL is based on management’s continuing evaluation of the risk characteristics and credit quality of the loan portfolio, assessment of current economic conditions, diversification and size of the portfolio, adequacy of collateral, past and anticipated loss experience, and the amount of nonperforming loans. The Company’s methodology for determining the ALLL is based on the requirements of ASC Section 310 10 35 450 20 two may Loans that are collectively evaluated for impairment are analyzed with general allowances being made as appropriate. For general allowances, historical loss trends are used in the estimation of losses in the current portfolio. These historical loss amounts are modified by other qualitative factors. The classes described above, which are based on the purpose code assigned to each loan, provide the starting point for the ALLL analysis. Management tracks the historical net charge-off activity at the purpose code level. The historical charge-off factor was calculated using the last twelve Management has identified a number of additional qualitative factors which it uses to supplement the historical charge-off factor because these factors are likely to cause estimated credit losses associated with the existing loan pools to differ from historical loss experience. The additional factors that are evaluated quarterly and updated using information obtained from internal, regulatory, and governmental sources are: national and local economic trends and conditions; levels of and trends in delinquency rates and nonaccrual loans; trends in volumes and terms of loans; effects of changes in lending policies; experience, ability, and depth of lending staff; value of underlying collateral; and concentrations of credit from a loan type, industry and/or geographic standpoint. Management reviews the loan portfolio on a quarterly basis using a defined, consistently applied process in order to make appropriate and timely adjustments to the ALLL. When information confirms all or part of specific loans to be uncollectible, these amounts are promptly charged off against the ALLL. The following tables summarize the primary segments of the loan portfolio and the activity within those segments (in thousands): Commercial and industrial Real estate- construction Real estate- residential mortgage Real estate- commercial mortgage Consumer installment Total ALLL balance at December 31, 2017 $ 999 $ 313 $ 1,760 $ 4,036 $ 82 $ 7,190 Charge-offs (9 ) - (74 ) (111 ) (135 ) (329 ) Recoveries 140 17 29 - 35 221 Provision 50 (241 ) 28 436 147 420 ALLL balance at June 30, 2018 $ 1,180 $ 89 $ 1,743 $ 4,361 $ 129 $ 7,502 Commercial and industrial Real estate- construction Real estate- residential mortgage Real estate- commercial mortgage Consumer installment Total ALLL balance at December 31, 2016 $ 448 $ 172 $ 2,818 $ 3,135 $ 25 $ 6,598 Charge-offs (435 ) - (74 ) (19 ) (154 ) (682 ) Recoveries 144 22 14 - 174 354 Provision 456 8 (991 ) 896 (34 ) 335 ALLL balance at June 30, 2017 $ 613 $ 202 $ 1,767 $ 4,012 $ 11 $ 6,605 Commercial and industrial Real estate- construction Real estate- residential mortgage Real estate- commercial mortgage Consumer installment Total ALLL balance at March 31, 2018 $ 1,256 $ 92 $ 1,782 $ 4,323 $ 98 $ 7,551 Charge-offs - - (74 ) (111 ) (130 ) (315 ) Recoveries 29 - 10 - 17 56 Provision (105 ) (3 ) 25 149 144 210 ALLL balance at June 30, 2018 $ 1,180 $ 89 $ 1,743 $ 4,361 $ 129 $ 7,502 Commercial and industrial Real estate- construction Real estate- residential mortgage Real estate- commercial mortgage Consumer installment Total ALLL balance at March 31, 2017 $ 616 $ 186 $ 2,523 $ 3,378 $ 17 $ 6,720 Charge-offs (415 ) - (7 ) - (52 ) (474 ) Recoveries 65 6 7 - 111 189 Provision 347 10 (756 ) 634 (65 ) 170 ALLL balance at June 30, 2017 $ 613 $ 202 $ 1,767 $ 4,012 $ 11 $ 6,605 The negative provision allocated to real estate construction loans in the amount of $241,000 six June 30, 2018 0.127% 0.775% first 2018.
