RECENT ACCOUNTING PRONOUNCEMENTS	NOTE 3 — RECENT ACCOUNTING PRONOUNCEMENTS In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. materially In February, 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income 76 In May 2017, the FASB issued ASU No. 2017-09, “Stock Compensation, Scope of Modification Accounting.” ASU 2017-09 clarifies when changes to the terms of conditions of a share-based payment award must be accounted for as modifications. Companies will apply the modification accounting guidance if any change in the value, vesting conditions or classification of the award occurs. The new guidance should reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications, as the guidance will allow companies to make certain non-substantive changes to awards without accounting for them as modifications. It does not change the accounting for modifications. ASU 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017. ASU 2017-09 did not have a material impact on the Company’s Consolidated Financial Statements. In March 2017, the FASB issued ASU No. 2017-08, “ Premium Amortization on Purchased Callable Debt Securities.” In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment.” In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments."

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES AND REPORTING, THE FAIR VALUE OPTION AND FAIR VALUE MEASUREMENTS	NOTE 8 – FAIR VALUE DISCLOSURES AND REPORTING, THE FAIR VALUE OPTION AND FAIR VALUE MEASUREMENTS FASB’s standards on financial instruments, and on fair value measurements and disclosures, require all entities to disclose in their financial statement footnotes the estimated fair values of financial instruments for which it is practicable to estimate fair values. In addition to disclosure requirements, FASB’s standard on investments requires that our debt securities which are classified as available-for-sale and our equity securities that have readily determinable fair values be measured and reported at fair value in our Consolidated Financial Statements. Certain impaired loans are also reported at fair value, as explained in greater detail below, and foreclosed assets are carried at the lower of cost or fair value. FASB’s standard on financial instruments permits companies to report certain other financial assets and liabilities at fair value, but we have not elected the fair value option for any of those financial instruments. Fair value measurement and disclosure standards also establish a framework for measuring fair values. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date. Further, the standards establish a fair value hierarchy that encourages an entity to maximize the use of observable inputs and limit the use of unobservable inputs when measuring fair values. The standards describe three levels of inputs that may be used to measure fair values: ⋅ Level 1 ⋅ Level 2 ⋅ Level 3 Fair value estimates are made at a specific point in time based on relevant market data and information about the financial instruments. The estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to realized gains and losses could have a significant effect on fair value estimates but have not been considered in those estimates. Because no active market exists for a significant portion of our financial instruments, fair value disclosures are based on judgments regarding current economic conditions, risk characteristics of various financial instruments and other factors. The estimates are subjective and involve uncertainties and matters of significant judgment, and therefore cannot be determined with precision. Changes in assumptions could significantly alter the fair values presented. The following methods and assumptions were used by the Company to estimate its financial instrument fair values disclosed at March 31, 2018 and December 31, 2017: ⋅ Cash and cash equivalents and fed funds sold ⋅ Securities (available-for-sale and held-to-maturity) ⋅ Loans and leases Recognition and Measurement of Financial Assets and Financial Liabilities ⋅ Loans held for sale ⋅ Collateral-dependent impaired loans ⋅ Accrued interest receivable ⋅ Deposits (noninterest-bearing and interest-bearing) ⋅ FHLB and other borrowings ⋅ Long-term borrowings ⋅ Subordinated debentures ⋅ Accrued interest payable ⋅ Off-balance sheet instruments As of March 31, 2018 ($ In Thousands) Fair Value Measurements Carrying Estimated Quoted Significant Significant Financial Instruments: Assets: Cash and cash equivalents $ 162,521 $ 162,521 $ 162,521 $ - $ - Securities available-for-sale 424,620 424,620 - 422,033 2,587 Securities held-to-maturity 6,000 7,242 - 7,242 - Other securities 11,308 11,308 n/a n/a n/a Loans, net 1,510,458 1,503,383 - - 1,503,383 Accrued interest receivable 8,027 8,027 - 3,000 5,027 Liabilities: Noninterest-bearing deposits $ 414,142 $ 414,142 $ - $ 414,142 $ - Interest-bearing deposits 1,577,502 1,557,342 - 1,557,342 - Subordinated debentures 10,310 10,310 - - 10,310 FHLB and other borrowings 29,034 29,034 - 29,034 - Accrued interest payable 490 490 - 490 - As of December 31, 2017 ($ In Thousands) Fair Value Measurements Carrying Estimated Quoted Significant Significant Financial Instruments: Assets: Cash and cash equivalents $ 91,921 $ 91,921 $ 91,921 $ - $ - Securities available-for-sale 356,893 356,893 920 353,404 2,569 Securities held-to-maturity 6,000 7,398 - 7,398 - Other securities 9,969 9,969 n/a n/a n/a Loans, net 1,221,808 1,230,237 - - 1,230,237 Accrued interest receivable 6,705 6,705 - 2,287 4,418 Liabilities: Noninterest-bearing deposits $ 301,989 $ 301,989 $ - $ 301,989 $ - Interest-bearing deposits 1,168,576 1,165,682 - 1,165,682 - Subordinated debentures 10,310 10,310 - - 10,310 FHLB and other borrowings 104,072 104,072 - 104,072 - Accrued interest payable 353 353 - 353 - Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include highly liquid government bonds, mortgage products and exchange traded equities. If quoted market prices are not available, securities are classified within Level 2 of the valuation hierarchy, and fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flow. Level 2 securities include U. S. agency securities, mortgage-backed securities, obligations of states and political subdivisions and certain corporate, asset-backed and other securities. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within Level 3 of the valuation hierarchy.

Impaired Loans Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment. Allowable methods for estimating fair value include using the fair value of the collateral for collateral dependent loans or, where a loan is determined not to be collateral dependent, using the discounted cash flow method. If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. If the impaired loan is determined not to be collateral dependent, then the discounted cash flow method is used. This method requires the impaired loan to be recorded at the present value of expected future cash flows discounted at the loan’s effective interest rate. The effective interest rate of a loan is the contractual interest rate adjusted for any net deferred loan fees or costs, or premium or discount existing at origination or acquisition of the loan. Impaired loans are classified within Level 3 of the fair value hierarchy. Other Real Estate Owned Other real estate owned acquired through loan foreclosure is initially recorded at fair value less estimated costs to sell, establishing a new cost basis. The adjustment at the time of foreclosure is recorded through the allowance for loan losses. Due to the subjective nature of establishing the fair value, the actual fair value of the other real estate owned or foreclosed asset could differ from the original estimate. If it is determined the fair value declines subsequent to foreclosure, a valuation allowance is recorded through non-interest expense. Operating costs associated with the assets are also recorded as non-interest expense. Gains and losses on the disposition of other real estate owned and foreclosed assets are netted and posted to other non-interest expense. Other real estate owned measured at fair value on a non-recurring basis at March 31, 2018, amounted to $ 7.4 ($ In Thousands) March 31, 2018 Fair Value Measurements Using Quoted Significant Significant Fair Value (Level 1) (Level 2) (Level 3) Impaired loans $ 9,608 $ - $ - $ 9,608 Other real estate owned 7,357 - - 7,357 December 31, 2017 Fair Value Measurements Using Quoted Significant Significant Fair Value (Level 1) (Level 2) (Level 3) Impaired loans $ 9,614 $ - $ - $ 9,614 Other real estate owned 7,158 - - 7,158

Loans Receivable, Net [Abstract]
LOANS	NOTE 10 – LOANS Loans typically provide higher yields than the other types of earning assets, and, thus, one of the Company's goals is for loans to be the largest category of the Company's earning assets. For the quarters ended March 31, 2018 and December 31, 2017, average loans accounted for 73.2 74.1 Generally, the Company will place a delinquent loan in nonaccrual status when the loan becomes 90 days or more past due. At the time a loan is placed in nonaccrual status, all interest which has been accrued on the loan but remains unpaid is reversed and deducted from earnings as a reduction of reported interest income. No additional interest is accrued on the loan balance until the collection of both principal and interest becomes reasonably certain.

These loans were recorded at estimated fair value at the acquisition date with no carryover of the related allowance for loan losses. The acquired loans were segregated as of the acquisition date between those considered to be performing (acquired non-impaired loans) and those with evidence of credit deterioration (acquired impaired loans). Acquired loans are considered impaired if there is evidence of credit deterioration and if it is probable, at acquisition, all contractually required payments will not be collected.

The Company uses the following definitions for risk ratings, which are consistent with the definitions used in supervisory guidance: Special Mention. Loans classified as special mention have a potential weakness that deserves management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date. Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans.

REVENUE FROM CONTRACTS WITH CUSTOMERS	NOTE 11 – REVENUE FROM CONTRACTS WITH CUSTOMERS On January 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers. The Company concluded that there is no change to the timing and pattern of revenue recognition for its current revenue streams or the presentation of revenue as gross versus net. No adjustment to retained earnings was required on the adoption date. Because there is no change to the timing and pattern of revenue recognition, there are no material changes to the Company’s processes and internal controls. All of the Company’s revenue from contracts with customers within the scope of ASC 606 is recognized within noninterest income. A description of the Company’s revenue streams accounted for under ASC 606 is as follows: Service Charges on Deposit Accounts : The Company earns fees from deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed at the point in the time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. Interchange Income : The Company earns interchange fees from debit and credit card holder transaction conducted through various payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided by the cardholder.
