Significant Accounting Policies [Text Block]	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations — December 31, 2017, 42 three three June 28, 2016, On August 22, 2017, the Bank entered into an Agreement and Plan of Reorganization (the “Merger Agreement”) with Arvest Bank, an Arkansas banking corporation (“Arvest”), and Arvest Acquisition Sub, Inc., an Arkansas corporation and a wholly-owned subsidiary of Arvest (“Acquisition Sub”), pursuant to which Arvest will acquire the Company and the Bank (the “Merger”). Pursuant to the Merger Agreement, each share of the Company’s common stock issued and outstanding as of the effective time of the Merger will be converted into a right to receive $10.28 November 15, 2017. The Merger is expected to close in late March April 2018 Principles of Consolidation — The accompanying consolidated financial statements include the accounts of the Company and its subsidiary described above. Intercompany transactions and balances have been eliminated in consolidation. Operating Segments — The Company’s operations are organized on a regional basis. While the chief decision-makers monitor revenue streams of various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Each region provides a group of similar community banking products and services, including loans, time deposits, and checking and savings accounts. The individual regions have similar operating and economic characteristics and are reported as one Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and such differences could be significant. Valuation of assets acquired and liabilities assumed in business combinations, valuation of real estate owned, fair value of financial instruments, valuation of deferred tax assets and the allowance for loan and lease losses are material estimates that are particularly susceptible to significant change in the near term. Cash Flow Reporting — For the purpose of presentation in the consolidated statements of cash flows, cash and cash equivalents includes cash on hand and amounts due from depository institutions, which includes interest bearing amounts available upon demand. Net cash flows are reported for customer loan and deposit transactions and short term borrowings with original maturities of three Investment Securities — The Company classifies investment securities into one two not Investment securities that the Company intends to hold for indefinite periods of time are classified as available for sale and are recorded at fair value. Unrealized holding gains and losses are excluded from earnings and reported net of tax in other comprehensive income. Investment securities in the available for sale portfolio may ’s asset and liability management practices and may Premiums are amortized into interest income using the interest method to the earlier of maturity or call date, or in the case of mortgage-backed securities, over the estimated life of the security. Discounts are accreted into interest income using the interest method over the period to maturity. The specific identification method of accounting is used to compute gains or losses on the sales of investment securities. Management evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis. In evaluating whether impairment is other than temporary, management primarily considers the length of time and the extent to which the fair value has been less than the amortized cost basis, the nature of the investment, the cause of the impairment, whether any periodic coupon payments have been missed, whether the security has been downgraded by rating agencies, and whether the Company intends to sell the security or it is more likely than not no December 31, 201 7, 2016 2015. Other Investments — The Bank is a member of the Federal Home Loan Bank (“FHLB”) system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may Loans Receivable — The Bank originates and maintains loans receivable that are substantially concentrated in its lending markets of Arkansas, Missouri and Southeast Oklahoma. The majority of the Bank’s loans are residential mortgage loans, nonfarm nonresidential loans, and commercial and industrial loans. The Bank’s policies generally call for collateral or other forms of security to be received from the borrower at the time of loan origination. Such collateral or other form of security is subject to changes in economic value due to various factors beyond the control of the Bank. Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are stated at unpaid principal balances, net of purchase premiums and discounts, charge-offs, the allowance for loan and lease losses, and deferred loan fees or costs. Interest income is accrued on the unpaid principal balance. Deferred loan fees or costs on loans are amortized or accreted to income using the level-yield method over the remaining period to contractual maturity without anticipating prepayments. Mortgage loans originated and committed for sale in the secondary market are carried at the lower of cost or estimated market value in the aggregate. Such loans are generally carried at cost due to the short period of time between funding and sale, generally within thirty Loans are considered past due when the contractual amounts due with respect to principal and/or interest are not received within 30 90 90 When interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. The interest on these loans is accounted for on the cash basis or cost recovery method until qualifying for return to accrual, except when doubt exists as to ultimate collectability of principal and interest. Under the cost recovery method, interest income is not no may 90 Acquisition Accounting and Acquired Loans — The Company accounts for its acquisitions under ASC Topic 805, Business Combinations No Purchased Credit Impaired Loans – Acquired loans and leases with evidence of credit deterioration since origination such that it is probable at acquisition that the Bank will be unable to collect all contractually required payments are accounted for under the guidance in ASC Topic 310 30, Loans and Debt Securities Acquired with Deteriorated Credit Quality Acquired loan amounts deemed uncollectible at acquisition date become part of the fair value calculation and are excluded from the ALLL. Following acquisition, a regular review is completed on acquired loans to determine if changes in estimated cash flows have occurred. Subsequent decreases in the amount expected to be collected may no Allowance for Loan and Lease Losses — The ALLL is a valuation allowance for probable incurred credit losses. The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the ALLL when management believes it is likely that a loan balance is uncollectible. Subsequent recoveries, if any, are credited to the ALLL. The ALLL represents management ’s estimate of incurred credit losses inherent in the Company’s loan portfolio as of the balance sheet date. The estimation of the ALLL is based on a variety of factors, including past loan loss experience, the current credit profiles of the Company’s borrowers, adverse situations that have occurred that may The ALLL consists of ( 1 2 Allocated (Specific) Allowance Allocated, or specific, allowances represent impairment measurements on certain impaired loans as further described below. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the note. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not ’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed.

The Company maintains a loss migration analysis that tracks loan losses and recoveries based on loan class as well as the loan risk grade assignment. At December 31, 201 7, four eight not not Rate Lock Commitments — The Bank enters into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (rate lock commitments) as well as corresponding commitments to sell such loans to investors. Rate lock commitments as well as the related sales commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments, along with any related fees received from potential borrowers, are recorded at fair value in derivative assets or liabilities, with changes in fair value recorded in the net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements, and for fixed rate commitments also considers the difference between current levels of interest rates and the committed rates. Real Estate Owned, Net — Real estate owned represents foreclosed assets held for sale and is initially recorded at estimated fair value less estimated costs to sell, establishing a new cost basis. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of carrying amount or fair value less costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Costs and expenses related to major additions and improvements are capitalized while maintenance and repairs that do not December 31, 2017, $1.0 one four Office Properties and Equipment, Net — Land is carried at cost. Buildings and equipment are stated at cost less accumulated depreciation and amortization. The Company computes depreciation using the straight-line method over the estimated useful lives of the individual assets, which range from 3 40 Cash Surrender Value of Life Insurance — Cash surrender value of life insurance represents life insurance purchased by the Bank on a qualifying group of officers with the Bank designated as owner and beneficiary of the policies. The yield on these policies is used to offset a portion of employment benefit costs. The policies are recorded on the consolidated statements of financial condition at their cash surrender values with changes in cash surrender values reported in noninterest income. Death benefits in excess of the cash surrender value are recorded in noninterest income at the time of death. Long-Lived Assets – Premises and equipment and other long-lived assets are reviewed for impairment when events indicate their carrying amount may not Goodwill and Other Intangible Assets Goodwill is not may basis over their weighted-average estimated useful lives, ranging from twelve thirteen may not not Goodwill is evaluated for impairment by comparing the estimated fair value of each reporting unit to its carrying value, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying amount, the goodwill of that reporting unit is not no Loan Commitments and Related Financial Instruments – Financial instruments include off-balance sheet credit instruments, such as commitments to originate loans and letters of credit, issued to meet customer financing needs. The face amount of these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Stock Based Compensation — Compensation cost for stock based compensation is recognized based on the fair value of these awards at the date of grant over the requisite service period. In most cases the requisite service period is the same 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. Income Taxes — The Company estimates its income taxes payable based on the amounts it expects to owe to the various taxing authorities (i.e. federal, state and local). In estimating income taxes, management assesses the relative merits and risks of the tax treatment of transactions, taking into account statutory, judicial and regulatory guidance in the context of the Company’s tax position. Management also relies on tax opinions, recent audits, and historical experience. Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various statement of financial condition assets and liabilities and gives current recognition to changes in tax rates and laws. D eferred tax assets and liabilities are recognized for the future tax consequences related to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for tax credits. Deferred tax assets are evaluated for recoverability using a consistent approach that considers the relative impact of negative and positive evidence, including our historical profitability and projections of future taxable income. A valuation allowance for deferred tax assets is established if, based on available evidence at the time the determination is made, that it is more likely than not not The Company recognizes a tax position as a benefit only if it is “more likely than not” 50% not not” no no Penalties and interest are classified as income tax expense when incurred. Interest Rate Risk — The Company’s asset base is exposed to risk including the risk resulting from changes in interest rates and changes in the timing of cash flows. The Company monitors the effect of such risks by considering the mismatch of the maturities of its assets and liabilities in the current interest rate environment and the sensitivity of assets and liabilities to changes in interest rates. The Company’s management has considered the effect of significant increases and decreases in interest rates and believes such changes, if they occurred, would be manageable and would not Earnings Per Common Share — Basic earnings per share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may Loss Contingencies – Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated.

Prior to origination, a borrower’s ability to repay is analyzed by reviewing financial information with a comparison of the sustainability of these cash flows to the proposed loan terms, with consideration given to possible changes in underlying business and economic conditions. The financial strength and support offered by any guarantors to the loan is evaluated and any collateral offered is assessed using internal and external valuation resources. Finally, the credit request is compared against the Bank’s board-approved written lending policies and standards. The ongoing risk in the loan portfolio is managed through regularly reviewing loans to assess key credit elements, providing for an adequate allowance for loan losses and diversifying the portfolio based on certain metrics including industry and collateral types, loan purpose and underlying source of repayment. Real Estate Loans – The real estate loan portfolio consists primarily of single family residential, commercial real estate and construction loans. Loans in this category are differentiated by whether the property owner or parties unrelated to the borrower occupy the property. This difference can directly affect the sensitivity of the source of loan repayment to changes in interest rates and market conditions, which can impact the underlying collateral value. Therefore, the analysis of these credits focuses on current and forecasted economic trends in certain sub-markets, including residential, industrial, retail, office and multi-family segments. Changes in these segments are influenced by both local and national cycles, which may Commercial Loans – This portfolio includes loans with funds used for commercial purposes including loans to finance enterprise, including agricultural, working capital needs; equipment purchases; accounts receivable and inventory and other similar business needs. The risk of loans in this category is driven by the cash flow and creditworthiness of the borrowers, the monitoring of which occurs through the ongoing analysis of interim financial information. Also, the terms of these loans are generally shorter than credits secured by real estate, helping to reduce the impact of changes in interest rates on the Bank’s interest rate sensitivity position. Consumer Loans – Our portfolio of consumer loans generally includes loans to individuals for household, family and other personal expenditures. Proceeds from such loans are used to, among other things, fund the purchase of automobiles, recreational vehicles, boats, mobile homes and for other similar purposes. Consumer loans generally have higher interest rates. However, such loans pose additional risks of collectability and loss when compared to certain other types of loans. The borrower’s ability to repay is of primary importance in the underwriting of consumer loans.

As part of the on-going monitoring of the credit quality of the Bank’s loan portfolio, the Bank categorizes loans into risk categories based on available and relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Bank analyzes loans individually by assigning a credit risk rating to loans on at least an annual basis for non-homogeneous loans over $1.0 Pass. Loans rated as pass generally meet or exceed normal credit standards. Factors influencing the level of pass grade include repayment source and strength, collateral, borrower cash flows, existence of and strength of guarantors, industry/business sector, financial trends, performance history, etc. Special Mention. Loans rated as special mention, while still adequately protected by the borrower’s repayment capability, exhibit distinct weakening trends. If left unchecked or uncorrected, these potential weaknesses may Substandard. Loans rated as substandard are inadequately protected by the current sound net worth and paying capacity of the borrower or the collateral pledged, if any. These assets must have a well-defined weakness based on objective evidence and be characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not Doubtful. Loans rated 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 rated as a loss are considered uncollectible and of such little value that continuance as an asset is not not no not may Based on analyses performed at December 31, 201 7 2016, December 31, 201 7 Pass Special Mention Substandard Total One- to four-family residential $ 379,407 $ 150 $ 11,668 $ 391,225 Multifamily residential 89,087 -- -- 89,087 Nonfarm nonresidential 543,427 287 13,471 557,185 Farmland 95,114 -- 1,672 96,786 Construction and land development 148,927 -- 8,526 157,453 Commercial 314,028 18,040 13,019 345,087 Consumer 35,644 -- 392 36,036 Total $ 1,605,634 $ 18,477 $ 48,748 $ 1,672,859 December 31, 201 6 Pass Special Mention Substandard Total One- to four-family residential $ 375,287 $ 206 $ 13,614 $ 389,107 Multifamily residential 92,460 -- -- 92,460 Nonfarm nonresidential 473,343 314 21,516 495,173 Farmland 92,131 -- 1,887 94,018 Construction and land development 116,269 -- 9,516 125,785 Commercial 317,069 -- 6,027 323,096 Consumer 35,953 1 311 36,265 Total $ 1,502,512 $ 521 $ 52,871 $ 1,555,904 As of December 31, 201 7 2016, not Troubled Debt Restructurings.

Prior to origination, a borrower’s ability to repay is analyzed by reviewing financial information with a comparison of the sustainability of these cash flows to the proposed loan terms, with consideration given to possible changes in underlying business and economic conditions. The financial strength and support offered by any guarantors to the loan is evaluated and any collateral offered is assessed using internal and external valuation resources. Finally, the credit request is compared against the Bank’s board-approved written lending policies and standards. The ongoing risk in the loan portfolio is managed through regularly reviewing loans to assess key credit elements, providing for an adequate allowance for loan losses and diversifying the portfolio based on certain metrics including industry and collateral types, loan purpose and underlying source of repayment. Real Estate Loans – The real estate loan portfolio consists primarily of single family residential, commercial real estate and construction loans. Loans in this category are differentiated by whether the property owner or parties unrelated to the borrower occupy the property. This difference can directly affect the sensitivity of the source of loan repayment to changes in interest rates and market conditions, which can impact the underlying collateral value. Therefore, the analysis of these credits focuses on current and forecasted economic trends in certain sub-markets, including residential, industrial, retail, office and multi-family segments. Changes in these segments are influenced by both local and national cycles, which may Commercial Loans – This portfolio includes loans with funds used for commercial purposes including loans to finance enterprise, including agricultural, working capital needs; equipment purchases; accounts receivable and inventory and other similar business needs. The risk of loans in this category is driven by the cash flow and creditworthiness of the borrowers, the monitoring of which occurs through the ongoing analysis of interim financial information. Also, the terms of these loans are generally shorter than credits secured by real estate, helping to reduce the impact of changes in interest rates on the Bank’s interest rate sensitivity position. Consumer Loans – Our portfolio of consumer loans generally includes loans to individuals for household, family and other personal expenditures. Proceeds from such loans are used to, among other things, fund the purchase of automobiles, recreational vehicles, boats, mobile homes and for other similar purposes. Consumer loans generally have higher interest rates. However, such loans pose additional risks of collectability and loss when compared to certain other types of loans. The borrower’s ability to repay is of primary importance in the underwriting of consumer loans.

As part of the on-going monitoring of the credit quality of the Bank’s loan portfolio, the Bank categorizes loans into risk categories based on available and relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Bank analyzes loans individually by assigning a credit risk rating to loans on at least an annual basis for non-homogeneous loans over $1.0 Pass. Loans rated as pass generally meet or exceed normal credit standards. Factors influencing the level of pass grade include repayment source and strength, collateral, borrower cash flows, existence of and strength of guarantors, industry/business sector, financial trends, performance history, etc. Special Mention. Loans rated as special mention, while still adequately protected by the borrower’s repayment capability, exhibit distinct weakening trends. If left unchecked or uncorrected, these potential weaknesses may Substandard. Loans rated as substandard are inadequately protected by the current sound net worth and paying capacity of the borrower or the collateral pledged, if any. These assets must have a well-defined weakness based on objective evidence and be characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not Doubtful. Loans rated 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 rated as a loss are considered uncollectible and of such little value that continuance as an asset is not not no not may Based on analyses performed at December 31, 201 7 2016, December 31, 201 7 Pass Special Mention Substandard Total One- to four-family residential $ 379,407 $ 150 $ 11,668 $ 391,225 Multifamily residential 89,087 -- -- 89,087 Nonfarm nonresidential 543,427 287 13,471 557,185 Farmland 95,114 -- 1,672 96,786 Construction and land development 148,927 -- 8,526 157,453 Commercial 314,028 18,040 13,019 345,087 Consumer 35,644 -- 392 36,036 Total $ 1,605,634 $ 18,477 $ 48,748 $ 1,672,859 December 31, 201 6 Pass Special Mention Substandard Total One- to four-family residential $ 375,287 $ 206 $ 13,614 $ 389,107 Multifamily residential 92,460 -- -- 92,460 Nonfarm nonresidential 473,343 314 21,516 495,173 Farmland 92,131 -- 1,887 94,018 Construction and land development 116,269 -- 9,516 125,785 Commercial 317,069 -- 6,027 323,096 Consumer 35,953 1 311 36,265 Total $ 1,502,512 $ 521 $ 52,871 $ 1,555,904 As of December 31, 201 7 2016, not Troubled Debt Restructurings.

	Dec. 31, 2017
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation — The accompanying consolidated financial statements include the accounts of the Company and its subsidiary described above. Intercompany transactions and balances have been eliminated in consolidation.
Segment Reporting, Policy [Policy Text Block]	Operating Segments — The Company’s operations are organized on a regional basis. While the chief decision-makers monitor revenue streams of various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Each region provides a group of similar community banking products and services, including loans, time deposits, and checking and savings accounts. The individual regions have similar operating and economic characteristics and are reported as one
Use of Estimates, Policy [Policy Text Block]	Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and such differences could be significant. Valuation of assets acquired and liabilities assumed in business combinations, valuation of real estate owned, fair value of financial instruments, valuation of deferred tax assets and the allowance for loan and lease losses are material estimates that are particularly susceptible to significant change in the near term.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash Flow Reporting — For the purpose of presentation in the consolidated statements of cash flows, cash and cash equivalents includes cash on hand and amounts due from depository institutions, which includes interest bearing amounts available upon demand. Net cash flows are reported for customer loan and deposit transactions and short term borrowings with original maturities of three
Marketable Securities, Policy [Policy Text Block]	Investment Securities — The Company classifies investment securities into one two not Investment securities that the Company intends to hold for indefinite periods of time are classified as available for sale and are recorded at fair value. Unrealized holding gains and losses are excluded from earnings and reported net of tax in other comprehensive income. Investment securities in the available for sale portfolio may ’s asset and liability management practices and may Premiums are amortized into interest income using the interest method to the earlier of maturity or call date, or in the case of mortgage-backed securities, over the estimated life of the security. Discounts are accreted into interest income using the interest method over the period to maturity. The specific identification method of accounting is used to compute gains or losses on the sales of investment securities. Management evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis. In evaluating whether impairment is other than temporary, management primarily considers the length of time and the extent to which the fair value has been less than the amortized cost basis, the nature of the investment, the cause of the impairment, whether any periodic coupon payments have been missed, whether the security has been downgraded by rating agencies, and whether the Company intends to sell the security or it is more likely than not no December 31, 201 7, 2016 2015.
Other Investments [Policy Text Block]	Other Investments — The Bank is a member of the Federal Home Loan Bank (“FHLB”) system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may
Finance, Loans and Leases Receivable, Policy [Policy Text Block]	Loans Receivable — The Bank originates and maintains loans receivable that are substantially concentrated in its lending markets of Arkansas, Missouri and Southeast Oklahoma. The majority of the Bank’s loans are residential mortgage loans, nonfarm nonresidential loans, and commercial and industrial loans. The Bank’s policies generally call for collateral or other forms of security to be received from the borrower at the time of loan origination. Such collateral or other form of security is subject to changes in economic value due to various factors beyond the control of the Bank. Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are stated at unpaid principal balances, net of purchase premiums and discounts, charge-offs, the allowance for loan and lease losses, and deferred loan fees or costs. Interest income is accrued on the unpaid principal balance. Deferred loan fees or costs on loans are amortized or accreted to income using the level-yield method over the remaining period to contractual maturity without anticipating prepayments. Mortgage loans originated and committed for sale in the secondary market are carried at the lower of cost or estimated market value in the aggregate. Such loans are generally carried at cost due to the short period of time between funding and sale, generally within thirty Loans are considered past due when the contractual amounts due with respect to principal and/or interest are not received within 30 90 90 When interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. The interest on these loans is accounted for on the cash basis or cost recovery method until qualifying for return to accrual, except when doubt exists as to ultimate collectability of principal and interest. Under the cost recovery method, interest income is not no may 90
Acquired Loans [Policy Text Block]	Acquisition Accounting and Acquired Loans — The Company accounts for its acquisitions under ASC Topic 805, Business Combinations No
Purchase Credit Impaired Loans, Policy [Policy Text Block]	Purchased Credit Impaired Loans – Acquired loans and leases with evidence of credit deterioration since origination such that it is probable at acquisition that the Bank will be unable to collect all contractually required payments are accounted for under the guidance in ASC Topic 310 30, Loans and Debt Securities Acquired with Deteriorated Credit Quality Acquired loan amounts deemed uncollectible at acquisition date become part of the fair value calculation and are excluded from the ALLL. Following acquisition, a regular review is completed on acquired loans to determine if changes in estimated cash flows have occurred. Subsequent decreases in the amount expected to be collected may no
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan and Lease Losses — The ALLL is a valuation allowance for probable incurred credit losses. The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the ALLL when management believes it is likely that a loan balance is uncollectible. Subsequent recoveries, if any, are credited to the ALLL. The ALLL represents management ’s estimate of incurred credit losses inherent in the Company’s loan portfolio as of the balance sheet date. The estimation of the ALLL is based on a variety of factors, including past loan loss experience, the current credit profiles of the Company’s borrowers, adverse situations that have occurred that may The ALLL consists of ( 1 2 Allocated (Specific) Allowance Allocated, or specific, allowances represent impairment measurements on certain impaired loans as further described below. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the note. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not ’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Each quarter, classified loans where the borrower’s total loan relationship exceeds $500,000 not $500,000 Groups of smaller balance homogeneous loans are collectively evaluated for impairment. Homogeneous loans are those that are considered to have common characteristics that provide for evaluation on an aggregate or pool basis. The Bank considers the characteristics of ( 1 one four 2 3 General Allowance The general component covers loans that are collectively evaluated for impairment and is based on historical loss experience adjusted for current qualitative environmental factors. The Company maintains a loss migration analysis that tracks loan losses and recoveries based on loan class as well as the loan risk grade assignment. At December 31, 201 7, four eight not not
Derivatives, Policy [Policy Text Block]	Rate Lock Commitments — The Bank enters into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (rate lock commitments) as well as corresponding commitments to sell such loans to investors. Rate lock commitments as well as the related sales commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments, along with any related fees received from potential borrowers, are recorded at fair value in derivative assets or liabilities, with changes in fair value recorded in the net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements, and for fixed rate commitments also considers the difference between current levels of interest rates and the committed rates.
Loans and Leases Receivable, Real Estate Acquired Through Foreclosure, Policy [Policy Text Block]	Real Estate Owned, Net — Real estate owned represents foreclosed assets held for sale and is initially recorded at estimated fair value less estimated costs to sell, establishing a new cost basis. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of carrying amount or fair value less costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Costs and expenses related to major additions and improvements are capitalized while maintenance and repairs that do not December 31, 2017, $1.0 one four
Property, Plant and Equipment, Policy [Policy Text Block]	Office Properties and Equipment, Net — Land is carried at cost. Buildings and equipment are stated at cost less accumulated depreciation and amortization. The Company computes depreciation using the straight-line method over the estimated useful lives of the individual assets, which range from 3 40
Life Settlement Contracts, Policy [Policy Text Block]	Cash Surrender Value of Life Insurance — Cash surrender value of life insurance represents life insurance purchased by the Bank on a qualifying group of officers with the Bank designated as owner and beneficiary of the policies. The yield on these policies is used to offset a portion of employment benefit costs. The policies are recorded on the consolidated statements of financial condition at their cash surrender values with changes in cash surrender values reported in noninterest income. Death benefits in excess of the cash surrender value are recorded in noninterest income at the time of death.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Long-Lived Assets – Premises and equipment and other long-lived assets are reviewed for impairment when events indicate their carrying amount may not
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangible Assets Goodwill is not may basis over their weighted-average estimated useful lives, ranging from twelve thirteen may not not Goodwill is evaluated for impairment by comparing the estimated fair value of each reporting unit to its carrying value, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying amount, the goodwill of that reporting unit is not no
Loan Commitments, Policy [Policy Text Block]	Loan Commitments and Related Financial Instruments – Financial instruments include off-balance sheet credit instruments, such as commitments to originate loans and letters of credit, issued to meet customer financing needs. The face amount of these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock Based Compensation — Compensation cost for stock based compensation is recognized based on the fair value of these awards at the date of grant over the requisite service period. In most cases the requisite service period is the same 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.
Income Tax, Policy [Policy Text Block]	Income Taxes — The Company estimates its income taxes payable based on the amounts it expects to owe to the various taxing authorities (i.e. federal, state and local). In estimating income taxes, management assesses the relative merits and risks of the tax treatment of transactions, taking into account statutory, judicial and regulatory guidance in the context of the Company’s tax position. Management also relies on tax opinions, recent audits, and historical experience. Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various statement of financial condition assets and liabilities and gives current recognition to changes in tax rates and laws. D eferred tax assets and liabilities are recognized for the future tax consequences related to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for tax credits. Deferred tax assets are evaluated for recoverability using a consistent approach that considers the relative impact of negative and positive evidence, including our historical profitability and projections of future taxable income. A valuation allowance for deferred tax assets is established if, based on available evidence at the time the determination is made, that it is more likely than not not The Company recognizes a tax position as a benefit only if it is “more likely than not” 50% not not” no no Penalties and interest are classified as income tax expense when incurred.
Interest Rate Risk [Policy Text Block]	Interest Rate Risk — The Company’s asset base is exposed to risk including the risk resulting from changes in interest rates and changes in the timing of cash flows. The Company monitors the effect of such risks by considering the mismatch of the maturities of its assets and liabilities in the current interest rate environment and the sensitivity of assets and liabilities to changes in interest rates. The Company’s management has considered the effect of significant increases and decreases in interest rates and believes such changes, if they occurred, would be manageable and would not
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Common Share — Basic earnings per share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may
Commitments and Contingencies, Policy [Policy Text Block]	Loss Contingencies – Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated.

[1]	Beginning in 2016, a Capital Conservation Buffer ("CCB") requirement became effective for banking organizations. The Basel III Rules limit capital distributions and certain discretionary bonus payments if the banking organization does not hold a "capital conservation buffer" consisting of 2.5% of common equity tier 1 capital, tier 1 capital and total capital to risk-weighted assets in addition to the amount necessary to meet minimum risk-based capital requirements. The capital conservation buffer began to be phased in on January 1, 2016, at 0.625% of risk-weighted assets, and will continue to be increased each year by that amount until fully implemented at 2.5% on January 1, 2019. When fully phased in on January 1, 2019, the Basel III Rules will require the Company and Bank to maintain (i) a minimum ratio of common equity tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 7.0% upon full implementation, (ii) a minimum ratio of tier 1 capital to risk-weighted assets of at least 6.0%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 8.50% upon full implementation, (iii) a minimum ratio of total capital to risk-weighted assets of at least 8.0%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 10.5% upon full implementation and (iv) a minimum leverage ratio of at least 4.0%.
