Presentation of cash flows Cash and due from banks $42,233,000 $30,532,000 December 31, 2016 2015, Investment securities All securities are evaluated to determine whether declines in fair value below their amortized cost are other-than-temporary. In estimating OTTI losses on AFS debt securities, management considers a number of factors including, but not limited to, (1) (2) (3) (4) If the Company lacks the intent to sell the security, and it is not more-likely-than-not the entity will be required to sell the security before recovery of its amortized cost basis, the Company will recognize the credit component of an OTTI of a debt security in earnings and the remaining portion in other comprehensive income. For held to maturity debt securities, the amount of an OTTI recorded in other comprehensive income for the noncredit portion would be amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security. In estimating OTTI losses on AFS equity securities management considers factors (1), (2) (3) Loans receivable, held for sale secondary Loans receivable, held for investment The Company discloses allowance for credit losses (also known allowance) and fair value by portfolio segment, and credit quality information, impaired financing receivables, nonaccrual status, and TDRs by class of financing receivable. A portfolio segment is the level at which the Company develops and documents a systematic methodology to determine its allowance for credit losses. A class of financing receivable is a further disaggregation of a portfolio segment based on risk characteristics and the Company’s method for monitoring and assessing credit risk. See the following information and Note 4. The Company’s portfolio segments are as follows: ● C&I ● CRE ● Residential real estate ● Installment and other consumer Direct financing leases are considered a segment within the overall loan/lease portfolio. The Company’s classes of loans receivable are as follows: ● C&I ● Owner-occupied CRE ● Commercial construction, land development, and other land loans that are not owner-occupied CRE ● Other non-owner-occupied CRE ● Residential real estate ● Installment and other consumer Direct financing leases are considered a class of financing receivable within the overall loan/lease portfolio. The accounting policies for direct financing leases are disclosed below. Generally, for all classes of loans receivable, loans are considered past due when contractual payments are delinquent for 31 For all classes of loans receivable, loans will generally be placed on nonaccrual status when the loan has become 90 ● It becomes evident that the borrower will not make payments, or will not or cannot meet the terms for renewal of a matured loan; ● When full repayment of principal and interest is not expected; ● When the loan is graded “doubtful”; ● When the borrower files bankruptcy and an approved plan of reorganization or liquidation is not anticipated in the near future; or ● When foreclosure action is initiated. When a loan is placed on nonaccrual status, income recognition is ceased. Previously recorded but uncollected amounts of interest on nonaccrual loans are reversed at the time the loan is placed on nonaccrual status. Generally, cash collected on nonaccrual loans is applied to principal. Should full collection of principal be expected, cash collected on nonaccrual loans can be recognized as interest income. For all classes of loans receivable, nonaccrual loans may ● The loan is current, and all principal and interest amounts contractually due have been made; ● All principal and interest amounts contractually due, including past due payments, are reasonably assured of repayment within a reasonable period; and ● There is a period of minimum repayment performance, as follows, by the borrower in accordance with contractual terms: o Six months of repayment performance for contractual monthly payments, or o One year of repayment performance for contractual quarterly or semi-annual payments. Direct finance leases receivable, held for investment 3% 25% Lease income is recognized on the interest method. Residual value is the estimated fair market value of the equipment on lease at lease termination. In estimating the equipment’s fair value at lease termination, the Company relies on historical experience by equipment type and manufacturer and, where available, valuations by independent appraisers, adjusted for known trends. The Company’s estimates are reviewed continuously to ensure reasonableness; however, the amounts the Company will ultimately realize could differ from the estimated amounts. If the review results in a lower estimate than had been previously established, a determination is made as to whether the decline in estimated residual value is other-than-temporary. If the decline in estimated unguaranteed residual value is judged to be other-than-temporary, the accounting for the transaction is revised using the changed estimate. The resulting reduction in the investment is recognized as a loss in the period in which the estimate is changed. An upward adjustment of the estimated residual value is not recorded. The policies for delinquency and nonaccrual for direct financing leases are materially consistent with those described above for all classes of loan receivables. The Company defers and amortizes fees and certain incremental direct costs over the contractual term of the lease as an adjustment to the yield. These initial direct leasing costs generally approximate 5.5% TDRs The following criteria, related to granting a concession, together or separately, create a TDR: ● A modification of terms of a debt such as one o The reduction of the stated interest rate. o The extension of the maturity date or dates at a stated interest rate lower than the current market rate for the new debt with similar risk. o The reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement. o The reduction of accrued interest. ● A transfer from the borrower/lessee to the Company of receivables from third ● The issuance or other granting of an equity position to the Company to fully or partially satisfy a debt unless the equity position is granted pursuant to existing terms for converting the debt into an equity position. Allowance For all portfolio segments, the allowance is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans/leases in light of historical experience, the nature and volume of the loan/lease portfolio, adverse situations that may A discussion of the risk characteristics and the allowance by each portfolio segment follows: For C&I loans ● Ability and stability of current management of the borrower; ● Stable earnings with positive financial trends; ● Sufficient cash flow to support debt repayment; ● Earnings projections based on reasonable assumptions; ● Financial strength of the industry and business; and ● Value and marketability of collateral. Collateral for C&I loans generally includes accounts receivable, inventory, equipment and real estate. The Company’s lending policy specifies approved collateral types and corresponding maximum advance percentages. The value of collateral pledged on loans must exceed the loan amount by a margin sufficient to absorb potential erosion of its value in the event of foreclosure and cover the loan amount plus costs incurred to convert it to cash. The Company’s lending policy specifies maximum term limits for C&I loans. For term loans, the maximum term is generally 7 3 5 365 In addition, the Company often takes personal guarantees or cosigners to help assure repayment. Loans may CRE loans may The Company’s lending policy also includes guidelines for real estate appraisals, including minimum appraisal standards based on certain transactions. In addition, the Company often takes personal guarantees to help assure repayment. In addition, management tracks the level of owner-occupied CRE loans versus non-owner occupied loans. Owner-occupied loans are generally considered to have less risk. As of December 31, 2016 2015, 30% 35%, The Company’s lending policy limits non-owner occupied CRE lending to 300% 100% December 31, 2016 2015, December 31, 2016, December 31, 2015. In some instances for all loans/leases, it may For C&I and CRE loans The specific component relates to loans that are classified as impaired, as defined below. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan. For C&I loans and all classes of CRE loans, a loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. 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 classified as impaired. 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. Impairment is measured on a case-by-case basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. The general component consists of quantitative and qualitative factors and covers non-impaired loans. The quantitative factors are based on historical charge-off experience and expected loss given default derived from the Company’s internal risk rating process. See below for a detailed description of the Company’s internal risk rating scale. The qualitative factors are determined based on an assessment of internal and/or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. For C&I and CRE loans, the Company utilizes the following internal risk rating scale: 1. 2. 3. – loans with satisfactory credit quality. Established borrowers with satisfactory financial condition, including credit quality, earnings, liquidity, capital and cash flow coverage. Management is capable and experienced. Collateral coverage and guarantor support, if applicable, are more than adequate. Includes loans secured by personal assets and business assets, including equipment, accounts receivable, inventory, and real estate. 4. – loans with moderate but still acceptable credit quality. The primary repayment source remains adequate; however, management’s ability to maintain consistent profitability is unproven or uncertain. Borrowers exhibit acceptable leverage and liquidity. May 5. – loans where the borrowers have generally performed as agreed, however unfavorable financial trends exist or are anticipated. Earnings may may may secondary may 6. may one 7. – loans which are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if applicable. These loans have a well-defined weakness or weaknesses which jeopardize repayment according to the contractual terms. There is distinct loss potential if the weaknesses are not corrected. Includes loans with insufficient cash flow coverage which are collateral dependent, other real estate owned, and repossessed assets. 8. – loans which have all the weaknesses inherent in a Substandard loan, with the added characteristic that existing weaknesses make full principal collection, on the basis of current facts, conditions and values, highly doubtful. The possibility of loss is extremely high, but because of pending factors, recognition of a loss is deferred until a more exact status can be determined. All doubtful loans will be placed on non-accrual, with all payments, including principal and interest, applied to principal reduction. The Company has certain loans risk-rated 7 7 450 20. 7 For term C&I and CRE loans or credit relationships with aggregate exposure greater than $1,000,000, 15 The Company’s Loan Quality area performs a documentation review of a sampling of C&I and CRE loans, the primary purpose of which is to ensure the credit is properly documented and closed in accordance with approval authorities and conditions. A review is also performed by the Company’s Internal Audit Department of a sampling of C&I and CRE loans for proper documentation, according to an approved schedule. Validation of the risk rating is also part of Internal Audit’s review (performed by Internal Loan Review). Additionally, over the past several years, the Company has contracted an independent outside third The Company leases machinery and equipment to C&I customers under direct financing leases For direct financing leases, the allowance consists of specific and general components. The specific component relates to leases that are classified as impaired, as defined for commercial loans above. For those leases that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired lease is lower than the carrying value of that lease. The general component consists of quantitative and qualitative factors and covers nonimpaired leases. The quantitative factors are based on historical charge-off experience for the entire lease portfolio. The qualitative factors are determined based on an assessment of internal and/or external influences on credit quality that are not fully reflected in the historical loss data. Generally, the Company’s residential real estate loans secondary one five 15 secondary The Company provides many types of installment and other consumer loans For residential real estate loans, and installment and other consumer loans TDRs are considered impaired loans/leases and are subject to the same allowance methodology as described above for impaired loans/leases by portfolio segment. Once a loan is classified as a TDR, it will remain a TDR until the loan is paid off, charged off, moved to OREO or restructured into a new note without a concession. TDR status may Credit related financial instruments Transfers of financial assets (1) (2) (3) ● Pro-rata ownership in an entire financial asset. ● From the date of the transfer, all cash flows received from entire financial assets are divided proportionately among the participating interest holders in an amount equal to their share of ownership. ● The rights of each participating interest holder have the same priority, and no participating interest holder’s interest is subordinated to the interest of another participating interest holder. That is, no participating interest holder is entitled to receive cash before any other participating interest holder under its contractual rights as a participating interest holder. ● No party has the right to pledge or exchange the entire financial asset unless all participating interest holders agree to pledge or exchange the entire financial asset.

The expected dividend yield assumption is based on the Company's current expectations about its anticipated dividend policy. Expected volatility is based on historical volatility of the Company's common stock price. The risk-free interest rate for periods within the contractual life of the option or purchase is based on the U.S. Treasury yield curve in effect at the time of the grant. The expected life of the option and purchase grants is derived using the “simplified” method and represents the period of time that options and purchases are expected to be outstanding. Historical data is used to estimate forfeitures used in the model. Two separate groups of employees (employees subject to broad based grants, and executive employees and directors) are used. As of December 31, 2016, $828,178 2.07 The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted price of the Company's common stock for the 587,961 December 31, 2016. December 31, 2016 $16.7 $11.8 December 31, 2016, 2015 2014, $1,525,902, $480,354, $173,105, Income taxes Deferred income taxes are provided under the liability method whereby deferred tax assets are recognized for deductible temporary differences and net operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more likely than not recognition threshold are measured as the largest amount of tax benefit that is more than 50 Interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the statements of income.

On August 31, 2016, ten 100% $80.0 The acquisition of CSB allowed the Company to expand its footprint into the Des Moines market. CSB has an experienced and capable leadership team that is committed to leading the Company’s efforts in the Des Moines area. CSB has demonstrated significant improvement in earnings and asset quality during the last three $581 In connection with the acquisition, during the second 2016, 1,215,000 $24.75 $29.8 May 23, 2016. Cash received from the common stock offering was used to help finance the purchase price of the acquisition. Additionally, the Company drew $5.0 $10.0 $30.0 11 $15.2 The Company accounted for the business combination under the acquisition method of accounting in accordance with ASC 805. one The excess of the consideration paid over the fair value of the net assets acquired is recorded as goodwill. This goodwill is not deductible for tax purposes. The Company has several areas of specialization, including government guaranteed lending, C&I lending, interest rate swaps, leasing, wealth management, private banking and municipal bond offerings that will be offered in this new market, increasing future earnings potential. There is also value added to the Company through having a footprint in a market that has strong growth potential. Additionally, there are qualitative benefits gained through the addition of a new charter including better leverage of centralized operations and increased lending limits. The experience and value of the personnel at CSB and their knowledge of the Des Moines MSA is also beneficial. The fair values of the assets acquired and liabilities assumed including the consideration paid and resulting goodwill is as follows: As of August 31, 2016 ASSETS Cash and due from banks $ 10,094,645 Federal funds sold 698,000 Interest-bearing deposits at financial institutions 14,730,157 Securities 102,640,029 Loans/leases receivable, net 419,029,277 Premises and equipment 20,684,880 Core deposit intangible 6,352,653 Restricted investment securities 1,512,900 Other real estate owned 650,000 Other assets 5,283,937 Total assets acquired $ 581,676,478 LIABILITIES Deposits $ 486,298,262 FHLB advances 20,368,877 Other liabilities 4,897,564 Total liabilities assumed $ 511,564,703 Net assets acquired $ 70,111,775 CONSIDERATION PAID: Cash $ 80,000,000 Total consideration paid $ 80,000,000 Goodwill $ 9,888,225 Loans acquired in a business combination are recorded and initially measured at their estimated fair value as of the acquisition date. Credit discounts are included in the determination of fair value. A third Purchased loans are segregated into two 310 30, 310 20, For PCI loans, the difference between the contractually required payments at acquisition and the cash flows expected to be collected is referred to as the non-accretable discount. Further, any excess cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the expected remaining life of the loan. Subsequent to the purchase date, increases in cash flows over those expected at the purchase date are recognized as interest income prospectively.

The evaluation consists of discussions with reputable and current vendors and management’s expertise and understanding of the current states of particular industries to determine informal valuations of the equipment. As necessary and where available, management will utilize valuations by independent appraisers. The large majority of leases with residual values contain a lease options rider which requires the lessee to pay the residual value directly, finance the payment of the residual value, or extend the lease term to pay the residual value. In these cases, the residual value is protected and the risk of loss is minimal. There were no losses related to residual values during the years ended December 31, 2016, 2015, 2014.

The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Fair Value Disclosures [Text Block]	Note 21. Accounting guidance on fair value measurements uses a hierarchy intended to maximize the use of observable inputs and minimize the use of unobservable inputs. This hierarchy includes three three ● Level 1 ● Level 2 ● Level 3 Assets measured at fair value on a recurring basis comprised the following at December 31, 2016 2015: Fair Value Measurements at Reporting Date Using Quoted Prices Significant in Active Other Significant Markets for Observable Unobservable Identical Assets Inputs Inputs Fair Value (Level 1) (Level 2) (Level 3) December 31, 2016: Securities available for sale: U.S. govt. sponsored agency securities $ 46,083,607 $ - $ 46,083,607 $ - Residential mortgage-backed securities 147,702,127 - 147,702,127 - Municipal securities 52,604,426 - 52,604,426 - Other securities 4,722,979 1,361 4,721,618 - Interest rate caps 576,527 - 576,527 - Interest rate swaps - assets 2,338,281 - 2,338,281 Total assets measured at fair value $ 254,027,947 $ 1,361 $ 254,026,586 $ - Interest rate swaps - liabilities $ 2,338,281 $ - $ 2,338,281 $ - Total liabilities measured at fair value $ 2,338,281 $ - $ 2,338,281 $ - December 31, 2015: Securities available for sale: U.S. govt. sponsored agency securities $ 213,537,379 $ - $ 213,537,379 $ - Residential mortgage-backed securities 80,670,135 - 80,670,135 - Municipal securities 27,578,588 - 27,578,588 - Other securities 1,648,880 411 1,648,469 - Interest rate caps 856,024 - 856,024 - Interest rate swaps - assets 3,044,525 - 3,044,525 Total assets measured at fair value $ 327,335,531 $ 411 $ 327,335,120 $ - Interest rate swaps - liabilities $ 3,044,525 $ - $ 3,044,525 $ - Total liabilities measured at fair value $ 3,044,525 $ - $ 3,044,525 $ - There were no transfers of assets or liabilities between Levels 1, 2, 3 December 31, 2016 2015. A small portion of the securities available for sale portfolio consists of common stock issued by various unrelated bank holding companies and mutual funds. The fair values used by the Company are obtained from an independent pricing service, which represent quoted market prices for the identical securities (Level 1 The remainder of the securities available for sale portfolio consists of securities whereby the Company obtains fair values from an independent pricing service. The fair values are determined by pricing models that consider observable market data, such as interest rate volatilities, LIBOR yield curve, credit spreads and prices from market makers and live trading systems (Level 2 Interest rate caps are used for the purpose of hedging interest rate risk. See Note 7 2 Interest rate swaps are executed for select commercial customers. The interest rate swaps are further described in Note 1 2 Certain financial assets are measured at fair value on a non-recurring basis; that is, the assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Assets measured at fair value on a non-recurring basis comprised the following at December 31, 2016 2015: Fair Value Measurements at Reporting Date Using Quoted Prices Significant in Active Other Significant Markets for Observable Unobservable Identical Assets Inputs Inputs Fair Value (Level 1) (Level 2) (Level 3) December 31, 2016: Impaired loans/leases $ 12,823,121 $ - $ - $ 12,823,121 Other real estate owned 5,964,952 - - 5,964,952 $ 18,788,073 $ - $ - $ 18,788,073 December 31, 2015: Impaired loans/leases $ 4,545,966 $ - $ - $ 4,545,966 Other real estate owned 7,722,711 - - 7,722,711 $ 12,268,677 $ - $ - $ 12,268,677 Impaired loans/leases are evaluated and valued at the time the loan/lease is identified as impaired, at the lower of cost or fair value and are classified as a Level 3 may may Other real estate owned in the table above consists of property acquired through foreclosures and settlements of loans.

For certain financial assets and liabilities, carrying value approximates fair value due to the nature of the financial instrument. These instruments include: cash and due from banks, federal funds sold, interest-bearing deposits at financial institutions, non-maturity deposits, and short-term borrowings. The Company used the following methods and assumptions in estimating the fair value of the following instruments: Securities held to maturity The fair values are estimated using pricing models that consider certain observable market data and some observable inputs, such as rate and term. Loans/leases receivable secondary Deposits FHLB advances and junior subordinated debentures Other borrowings Commitments to extend credit

In estimating OTTI losses on AFS debt securities, management considers a number of factors including, but not limited to, (1) (2) (3) (4) If the Company lacks the intent to sell the security, and it is not more-likely-than-not the entity will be required to sell the security before recovery of its amortized cost basis, the Company will recognize the credit component of an OTTI of a debt security in earnings and the remaining portion in other comprehensive income. For held to maturity debt securities, the amount of an OTTI recorded in other comprehensive income for the noncredit portion would be amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security.

Finance, Loan and Lease Receivables, Held-for-sale, Policy [Policy Text Block]	Loans receivable, held for sale secondary
Finance, Loans and Leases Receivable, Policy [Policy Text Block]	Loans receivable, held for investment The Company discloses allowance for credit losses (also known allowance) and fair value by portfolio segment, and credit quality information, impaired financing receivables, nonaccrual status, and TDRs by class of financing receivable. A portfolio segment is the level at which the Company develops and documents a systematic methodology to determine its allowance for credit losses. A class of financing receivable is a further disaggregation of a portfolio segment based on risk characteristics and the Company’s method for monitoring and assessing credit risk. See the following information and Note 4. The Company’s portfolio segments are as follows: ● C&I ● CRE ● Residential real estate ● Installment and other consumer Direct financing leases are considered a segment within the overall loan/lease portfolio. The Company’s classes of loans receivable are as follows: ● C&I ● Owner-occupied CRE ● Commercial construction, land development, and other land loans that are not owner-occupied CRE ● Other non-owner-occupied CRE ● Residential real estate ● Installment and other consumer Direct financing leases are considered a class of financing receivable within the overall loan/lease portfolio. The accounting policies for direct financing leases are disclosed below. Generally, for all classes of loans receivable, loans are considered past due when contractual payments are delinquent for 31 For all classes of loans receivable, loans will generally be placed on nonaccrual status when the loan has become 90 ● It becomes evident that the borrower will not make payments, or will not or cannot meet the terms for renewal of a matured loan; ● When full repayment of principal and interest is not expected; ● When the loan is graded “doubtful”; ● When the borrower files bankruptcy and an approved plan of reorganization or liquidation is not anticipated in the near future; or ● When foreclosure action is initiated. When a loan is placed on nonaccrual status, income recognition is ceased. Previously recorded but uncollected amounts of interest on nonaccrual loans are reversed at the time the loan is placed on nonaccrual status. Generally, cash collected on nonaccrual loans is applied to principal. Should full collection of principal be expected, cash collected on nonaccrual loans can be recognized as interest income. For all classes of loans receivable, nonaccrual loans may ● The loan is current, and all principal and interest amounts contractually due have been made; ● All principal and interest amounts contractually due, including past due payments, are reasonably assured of repayment within a reasonable period; and ● There is a period of minimum repayment performance, as follows, by the borrower in accordance with contractual terms: o Six months of repayment performance for contractual monthly payments, or o One year of repayment performance for contractual quarterly or semi-annual payments. Direct finance leases receivable, held for investment 3% 25% Lease income is recognized on the interest method. Residual value is the estimated fair market value of the equipment on lease at lease termination. In estimating the equipment’s fair value at lease termination, the Company relies on historical experience by equipment type and manufacturer and, where available, valuations by independent appraisers, adjusted for known trends. The Company’s estimates are reviewed continuously to ensure reasonableness; however, the amounts the Company will ultimately realize could differ from the estimated amounts. If the review results in a lower estimate than had been previously established, a determination is made as to whether the decline in estimated residual value is other-than-temporary. If the decline in estimated unguaranteed residual value is judged to be other-than-temporary, the accounting for the transaction is revised using the changed estimate. The resulting reduction in the investment is recognized as a loss in the period in which the estimate is changed. An upward adjustment of the estimated residual value is not recorded. The policies for delinquency and nonaccrual for direct financing leases are materially consistent with those described above for all classes of loan receivables. The Company defers and amortizes fees and certain incremental direct costs over the contractual term of the lease as an adjustment to the yield. These initial direct leasing costs generally approximate 5.5%
Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]	TDRs The following criteria, related to granting a concession, together or separately, create a TDR: ● A modification of terms of a debt such as one o The reduction of the stated interest rate. o The extension of the maturity date or dates at a stated interest rate lower than the current market rate for the new debt with similar risk. o The reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement. o The reduction of accrued interest. ● A transfer from the borrower/lessee to the Company of receivables from third ● The issuance or other granting of an equity position to the Company to fully or partially satisfy a debt unless the equity position is granted pursuant to existing terms for converting the debt into an equity position.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance For all portfolio segments, the allowance is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans/leases in light of historical experience, the nature and volume of the loan/lease portfolio, adverse situations that may A discussion of the risk characteristics and the allowance by each portfolio segment follows: For C&I loans ● Ability and stability of current management of the borrower; ● Stable earnings with positive financial trends; ● Sufficient cash flow to support debt repayment; ● Earnings projections based on reasonable assumptions; ● Financial strength of the industry and business; and ● Value and marketability of collateral. Collateral for C&I loans generally includes accounts receivable, inventory, equipment and real estate. The Company’s lending policy specifies approved collateral types and corresponding maximum advance percentages. The value of collateral pledged on loans must exceed the loan amount by a margin sufficient to absorb potential erosion of its value in the event of foreclosure and cover the loan amount plus costs incurred to convert it to cash. The Company’s lending policy specifies maximum term limits for C&I loans. For term loans, the maximum term is generally 7 3 5 365 In addition, the Company often takes personal guarantees or cosigners to help assure repayment. Loans may CRE loans may The Company’s lending policy also includes guidelines for real estate appraisals, including minimum appraisal standards based on certain transactions. In addition, the Company often takes personal guarantees to help assure repayment. In addition, management tracks the level of owner-occupied CRE loans versus non-owner occupied loans. Owner-occupied loans are generally considered to have less risk. As of December 31, 2016 2015, 30% 35%, The Company’s lending policy limits non-owner occupied CRE lending to 300% 100% December 31, 2016 2015, December 31, 2016, December 31, 2015. In some instances for all loans/leases, it may For C&I and CRE loans The specific component relates to loans that are classified as impaired, as defined below. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan are lower than the carrying value of that loan. For C&I loans and all classes of CRE loans, a loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. 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 classified as impaired. 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. Impairment is measured on a case-by-case basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. The general component consists of quantitative and qualitative factors and covers non-impaired loans. The quantitative factors are based on historical charge-off experience and expected loss given default derived from the Company’s internal risk rating process. See below for a detailed description of the Company’s internal risk rating scale. The qualitative factors are determined based on an assessment of internal and/or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. For C&I and CRE loans, the Company utilizes the following internal risk rating scale: 1. 2. 3. – loans with satisfactory credit quality. Established borrowers with satisfactory financial condition, including credit quality, earnings, liquidity, capital and cash flow coverage. Management is capable and experienced. Collateral coverage and guarantor support, if applicable, are more than adequate. Includes loans secured by personal assets and business assets, including equipment, accounts receivable, inventory, and real estate. 4. – loans with moderate but still acceptable credit quality. The primary repayment source remains adequate; however, management’s ability to maintain consistent profitability is unproven or uncertain. Borrowers exhibit acceptable leverage and liquidity. May 5. – loans where the borrowers have generally performed as agreed, however unfavorable financial trends exist or are anticipated. Earnings may may may secondary may 6. may one 7. – loans which are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if applicable. These loans have a well-defined weakness or weaknesses which jeopardize repayment according to the contractual terms. There is distinct loss potential if the weaknesses are not corrected. Includes loans with insufficient cash flow coverage which are collateral dependent, other real estate owned, and repossessed assets. 8. – loans which have all the weaknesses inherent in a Substandard loan, with the added characteristic that existing weaknesses make full principal collection, on the basis of current facts, conditions and values, highly doubtful. The possibility of loss is extremely high, but because of pending factors, recognition of a loss is deferred until a more exact status can be determined. All doubtful loans will be placed on non-accrual, with all payments, including principal and interest, applied to principal reduction. The Company has certain loans risk-rated 7 7 450 20. 7 For term C&I and CRE loans or credit relationships with aggregate exposure greater than $1,000,000, 15 The Company’s Loan Quality area performs a documentation review of a sampling of C&I and CRE loans, the primary purpose of which is to ensure the credit is properly documented and closed in accordance with approval authorities and conditions. A review is also performed by the Company’s Internal Audit Department of a sampling of C&I and CRE loans for proper documentation, according to an approved schedule. Validation of the risk rating is also part of Internal Audit’s review (performed by Internal Loan Review). Additionally, over the past several years, the Company has contracted an independent outside third The Company leases machinery and equipment to C&I customers under direct financing leases For direct financing leases, the allowance consists of specific and general components. The specific component relates to leases that are classified as impaired, as defined for commercial loans above. For those leases that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired lease is lower than the carrying value of that lease. The general component consists of quantitative and qualitative factors and covers nonimpaired leases. The quantitative factors are based on historical charge-off experience for the entire lease portfolio. The qualitative factors are determined based on an assessment of internal and/or external influences on credit quality that are not fully reflected in the historical loss data. Generally, the Company’s residential real estate loans secondary one five 15 secondary The Company provides many types of installment and other consumer loans For residential real estate loans, and installment and other consumer loans TDRs are considered impaired loans/leases and are subject to the same allowance methodology as described above for impaired loans/leases by portfolio segment. Once a loan is classified as a TDR, it will remain a TDR until the loan is paid off, charged off, moved to OREO or restructured into a new note without a concession. TDR status may

The expected dividend yield assumption is based on the Company's current expectations about its anticipated dividend policy. Expected volatility is based on historical volatility of the Company's common stock price. The risk-free interest rate for periods within the contractual life of the option or purchase is based on the U.S. Treasury yield curve in effect at the time of the grant. The expected life of the option and purchase grants is derived using the “simplified” method and represents the period of time that options and purchases are expected to be outstanding. Historical data is used to estimate forfeitures used in the model. Two separate groups of employees (employees subject to broad based grants, and executive employees and directors) are used. As of December 31, 2016, $828,178 2.07 The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted price of the Company's common stock for the 587,961 December 31, 2016.

Income Tax, Policy [Policy Text Block]	Income taxes Deferred income taxes are provided under the liability method whereby deferred tax assets are recognized for deductible temporary differences and net operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more likely than not recognition threshold are measured as the largest amount of tax benefit that is more than 50 Interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the statements of income.

[1]	Management performs an evaluation of the estimated unguaranteed residual values of leased assets on an annual basis, at a minimum. The evaluation consists of discussions with reputable and current vendors and management’s expertise and understanding of the current states of particular industries to determine informal valuations of the equipment. As necessary and where available, management will utilize valuations by independent appraisers. The large majority of leases with residual values contain a lease options rider which requires the lessee to pay the residual value directly, finance the payment of the residual value, or extend the lease term to pay the residual value. In these cases, the residual value is protected and the risk of loss is minimal.
[2]	Performing = loans/leases accruing and less than 90 days past due. Nonperforming = loans/leases on nonaccrual, accruing loans/leases that are greater than or equal to 90 days past due, and accruing troubled debt restructurings.

[1]	Management performs an evaluation of the estimated unguaranteed residual values of leased assets on an annual basis, at a minimum. The evaluation consists of discussions with reputable and current vendors and management’s expertise and understanding of the current states of particular industries to determine informal valuations of the equipment. As necessary and where available, management will utilize valuations by independent appraisers. The large majority of leases with residual values contain a lease options rider which requires the lessee to pay the residual value directly, finance the payment of the residual value, or extend the lease term to pay the residual value. In these cases, the residual value is protected and the risk of loss is minimal.
