Earnings per share

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	3. Earnings per share: Basic earnings per share is computed by dividing net income (loss) divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect 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. The following table provides a reconciliation between the computation of basic earnings per share and diluted earnings per share for the three and nine months ended September 30, 2019 and 2018: Three months ended September 30, 2019 2018 Numerator: Net income $ 2,266 $ 2,788 Denominator: Basic 9,173,901 9,100,616 Dilutive options 7,175 56,315 Diluted 9,181,076 9,156,931 Earnings per share: Basic $ 0.25 $ 0.30 Diluted $ 0.25 $ 0.30 Nine months ended September 30, 2019 2018 Numerator: Net income $ 3,013 $ 8,386 Denominator: Basic 9,159,281 9,089,636 Dilutive options 12,734 53,405 Diluted 9,172,015 9,143,041 Earnings per share: Basic $ 0.33 $ 0.92 Diluted $ 0.33 $ 0.92 For the three and nine months ended September 30, 2019, there were 43,350 outstanding stock options that were excluded from the dilutive earnings per share calculation because their effect was antidilutive. None of the outstanding stock options for the three and nine months ended September 30, 2018 were excluded from the diluted earnings per share calculation.

Securities and short-term investment activities are conducted with a diverse group of government entities, corporations and state and local municipalities. The counterparty’s creditworthiness and type of collateral is evaluated on a case-by-case The fair value and gross unrealized losses of investment securities with unrealized losses for which an other-than-temporary impairment (“OTTI”) has not been recognized at September 30, 2019 and December 31, 2018, aggregated by investment category and length of time that the individual securities have been in a continuous unrealized loss position, are summarized as follows: Less Than 12 Months 12 Months or More Total September 30, 2019 Fair Unrealized Fair Unrealized Fair Unrealized U.S. Treasury securities $ $ $ $ $ $ State and municipals: Taxable 280 4 280 4 Tax-exempt Mortgage-backed securities: U.S. Government agencies 19,723 308 19,723 308 U.S. Government-sponsored enterprises 3,925 59 3,925 59 Corporate debt obligation 3,246 254 3,246 254 Total $ 20,003 $ 312 $ 7,171 $ 313 $ 27,174 $ 625 Less Than 12 Months 12 Months or More Total December 31, 2018 Fair Unrealized Fair Unrealized Fair Unrealized State and municipals: Taxable $ 2,300 $ 4 $ 22,943 $ 888 $ 25,243 $ 892 Tax-exempt 1,950 32 9,556 164 11,506 196 Mortgage-backed securities: U.S. Government agencies 7,862 66 1,216 40 9,078 106 U.S. Government-sponsored enterprises 18,110 163 7,133 288 25,243 451 Corporate debt obligation 8,758 757 8,758 757 Total $ 30,222 $ 265 $ 49,606 $ 2,137 $ 79,828 $ 2,402 The Company had 30 investment securities, consisting of one taxable state and municipal obligation, 28 mortgage-backed securities, and one corporate debt obligation that were in unrealized loss positions at September 30, 2019. Of these securities, six mortgage-backed securities and one corporate debt obligation were in a continuous unrealized loss position for twelve months or more. Management does not consider the unrealized losses on the debt securities, as a result of changes in interest rates, to be OTTI based on historical evidence that indicates the cost of these securities is recoverable within a reasonable period of time in relation to normal cyclical changes in the market rates of interest. Moreover, because there has been no material change in the credit quality of the issuers or other events or circumstances that may cause a significant adverse impact on the fair value of these securities, and management does not intend to sell these securities and it is unlikely that the Company will be required to sell these securities before recovery of their amortized cost basis, which may be maturity, the Company does not consider the unrealized losses to be OTTI at September 30, 2019. There was no OTTI recognized for the three and nine months ended September 30, 2019 and 2018. The Company had 92 investment securities, consisting of 39 taxable state and municipal obligations, 22 tax-exempt tax-exempt

Loans are individually analyzed for credit risk by classifying them within the Company’s internal risk rating system. The Company’s risk rating classifications are defined as follows: • Pass—A loan to borrowers with acceptable credit quality and risk that is not adversely classified as Substandard, Doubtful, Loss or designated as Special Mention. • Special Mention—A loan that has potential weaknesses that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the institution’s credit position at some future date. Special Mention loans are not adversely classified since they do not expose the Company to sufficient risk to warrant adverse classification. • Substandard—A loan that is inadequately protected by the current sound worth and paying capacity of the obligor or by the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. • Doubtful—A loan classified as Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make the collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. • Loss—A loan classified as Loss is considered uncollectible and of such little value that its continuance as a bankable loan is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may occur in the future. The following tables present the major classification of loans summarized by the aggregate pass rating and the classified ratings of special mention, substandard and doubtful within the Company’s internal risk rating system at September 30, 2019 and December 31, 2018: September 30, 2019 Pass Special Substandard Doubtful Total Commercial $ 117,183 $ 8,221 $ 3,848 $ 129,252 Real estate: Construction 58,399 159 58,558 Commercial 447,077 13,889 18,299 479,265 Residential 202,774 2,038 2,403 207,215 Consumer 9,216 9,216 Total $ 834,649 $ 24,307 $ 24,550 $ 883,506 December 31, 2018 Pass Special Substandard Doubtful Total Commercial $ 109,609 $ 9,123 $ 4,187 $ 122,919 Real estate: Construction 39,265 291 39,556 Commercial 471,364 13,106 13,127 497,597 Residential 216,218 2,126 2,771 221,115 Consumer 11,997 11,997 Total $ 848,453 $ 24,355 $ 20,376 $ 893,184 The following tables present the classes of the loan portfolio summarized by the aging categories of performing loans and nonaccrual loans as of September 30, 2019 and December 31, 2018.

Troubled debt restructured loans are loans with original terms, interest rate, or both, that have been modified as a result of a deterioration in the borrower’s financial condition and a concession has been granted that the Company would not otherwise consider. Unless on nonaccrual, interest income on these loans is recognized when earned, using the interest method. The Company offers a variety of modifications to borrowers that would be considered concessions. The modification categories offered generally fall within the following categories: • Rate Modification—A modification in which the interest rate is changed to a below market rate. • Term Modification—A modification in which the maturity date, timing of payments or frequency of payments is changed. • Interest Only Modification—A modification in which the loan is converted to interest only payments for a period of time. • Payment Modification—A modification in which the dollar amount of the payment is changed, other than an interest only modification described above. • Combination Modification—Any other type of modification, including the use of multiple categories above. Included in the commercial loan and commercial and residential real estate categories are troubled debt restructurings that are classified as impaired. Troubled debt restructurings totaled $2,729 at September 30, 2019, $2,925 at December 31, 2018 and $4,766 at September 30, 2018. There were no loans modified as troubled debt restructuring during the third quarter of 2019 and one loan modified during the nine months ended September 30, 2019. There were no loans modified as troubled debt restructuring for the three and nine months ended September 30, 2018. During the three months ended September 30, 2019, there were no defaults on loans restructured and one default on a restructured loan totaling $222 during the nine months ended September 30, 2019. During the three months ended September 30, 2018, there were no defaults on loans restructured and six defaults on loans restructured totaling $1,474 during the nine months ended September 30, 2018. Purchased loans are initially recorded at their acquisition date fair values. The carryover of the allowance for loan losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for purchased loans are based on a cash flow methodology that involves assumptions and judgments as to credit risk, default rates, loss severity, collateral values, discount rates, payment speeds, and prepayment risk. As part of its acquisition due diligence process, the Bank reviews the acquired institution’s loan grading system and the associated risk rating for loans. In performing this review, the Bank considers cash flows, debt service coverage, delinquency status, accrual status, and collateral for the loan. This process allows the Bank to clearly identify the population of acquired loans that had evidence of deterioration in credit quality since origination and for which it was probable, at acquisition, that the Bank would be unable to collect all contractually required payments. All such loans identified by the Bank are considered to be within the scope of ASC 310-30, As a result of the merger with CBT, effective October 1, 2017, the Bank identified 37 PCI loans. As part of the merger with Citizens, effective December 31, 2015, the Bank identified 10 PCI loans. As a result of the consolidation with Union effective November 1, 2013, the Bank identified 14 PCI loans. For all PCI loans, the excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loan. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable discount. The non-accretable discount represents estimated future credit losses expected to be incurred over the life of the loan. Subsequent decreases to the expected cash flows require the Bank to evaluate the need for an allowance for loan losses on these loans. Subsequent improvements in expected cash flows result in the reversal of a corresponding amount of the non-accretable discount which the Bank then reclassifies as an accretable discount that is recognized into interest income over the remaining life of the loan. The Bank’s evaluation of the amount of future cash flows that it expects to collect is based on a cash flow methodology that involves assumptions and judgments as to credit risk, collateral values, discount rates, payment speeds, and prepayment risk. Charge-offs of the principal amount on purchased impaired loans are first applied to the non-accretable discount. For purchased loans that are not deemed impaired at acquisition, credit discounts representing principal losses expected over the life of the loans are a component of the initial fair value, and the discount is accreted to interest income over the life of the asset. Subsequent to the purchase date, the method used to evaluate the sufficiency of the credit discount is similar to originated loans, and if necessary, additional reserves are recognized in the allowance for loan losses. The unpaid principal balances and the related carrying amount of acquired loans as of September 30, 2019 and December 31, 2018 were as follows: September 30, December 31, Credit impaired purchased loans evaluated individually for incurred credit losses: Outstanding balance $ 2,975 $ 7,491 Carrying Amount 1,781 3,825 Other purchased loans evaluated collectively for incurred credit losses: Outstanding balance 265,901 315,013 Carrying Amount 265,778 314,328 Total Purchased Loans: Outstanding balance 268,876 322,504 Carrying Amount $ 267,559 $ 318,153 As of the indicated dates, the changes in the accretable discount related to the purchased credit impaired loans were as follows: Three Months Ended Nine Months Ended 2019 2018 2019 2018 Balance—beginning of period $ 305 $ 1,439 $ 579 $ 2,129 Accretion recognized during the period (1,301 ) (819 ) (2,075 ) (2,673 ) Net reclassification from non-accretable to accretable 1,103 208 1,603 1,372 Balance—end of period $ 107 $ 828 $ 107 $ 828 The Company is a party to financial instruments with off-balance Unused commitments at September 30, 2019, totaled $167,736 consisting of $96,519 in commitments to extend credit, $65,893 in unused portions of lines of credit and $5,324 in standby letters of credit. Due to fixed maturity dates, specified conditions within these instruments, and the ultimate needs of our customers, many will expire without being drawn upon. We believe that amounts actually drawn upon can be funded in the normal course of operations and therefore, do not represent a significant liquidity risk to us. In comparison, unused commitments, at December 31, 2018, totaled $161,732, consisting of $96,431 in commitments to extend credit, $59,512 in unused portions of lines of credit and $5,789 in standby letters of credit.

Fair Value Disclosures [Abstract]
Fair value estimates	8. Fair value estimates: The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosure under GAAP. Fair value estimates are calculated without attempting to estimate the value of anticipated future business and the value of certain assets and liabilities that are not considered financial. Accordingly, such assets and liabilities are excluded from disclosure requirements. In accordance with FASB ASC 820, “Fair Value Measurements and Disclosures”, fair value is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets. In many cases, these values cannot be realized in immediate settlement of the instrument. Current fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction that is not a forced liquidation or distressed sale between participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. In accordance with GAAP, the Company groups its assets and liabilities generally measured at fair value into three levels based on market information or other fair value estimates in which the assets and liabilities are traded or valued, and the reliability of the assumptions used to determine fair value. These levels include: • Level 1: Unadjusted quoted prices of identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. An asset’s or liability’s placement in the fair value hierarchy is based on the lowest level of input that is significant to the fair value estimate.

Revenue from Contract with Customer [Abstract]
Revenue recognition	Note 9. Revenue recognition: On January 1, 2018, the Company adopted ASU No. 2014-09 Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as trust and asset management income, deposit related fees, interchange fees, merchant income, and other fees. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest revenue streams in-scope Service Charges, Fees and Commissions Service charges on deposit accounts consist of monthly service fees, check orders, and other deposit account related fees. The Company’s performance obligation for monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. Fees, exchange, and other service charges are primarily comprised of debit and credit card income, ATM fees, merchant services income, and other service charges. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as Mastercard. Such income is presented net of network expenses as the Company acts as an agent in these transactions. ATM fees are primarily generated when a Company cardholder uses a non-Company non-Company Other noninterest income consists of other recurring revenue streams such as commissions from sales of mutual funds and other investments, investment advisor fees from wealth management products, safe deposit box rental fees, and other miscellaneous revenue streams. Commissions from the sale of mutual funds and other investments are recognized on trade date, which is when the Company has satisfied its performance obligation. The Company also receives periodic service fees or trailers from mutual fund companies typically based on a percentage of net asset value. Trailer revenue is recorded over time, usually monthly or quarterly, as net asset value is determined. Investment advisor fees from wealth management products is earned over time and based on an annual percentage rate of the net asset value. The investment advisor fees are charged to the customer’s account in advance on the first month of the quarter, and the revenue is recognized over the following three-month period. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation. Trust and Asset Management Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end The following presents noninterest income, segregated by revenue streams in-scope out-of-scope Three Months Ended Nine Months Ended September 30, 2019 2018 2019 2018 Noninterest Income: In-scope Service charges, fees and commissions $ 1,129 $ 1,267 $ 3,497 $ 4,146 Trust and asset management 540 425 1,564 1,243 Noninterest income (in-scope 1,669 1,692 5,061 5,389 Noninterest income (out-of-scope 291 362 836 1,151 Total noninterest income $ 1,960 $ 2,054 $ 5,897 $ 6,540 Contract Balances A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration, resulting in a contract receivable, or before payment is due, resulting in a contract asset. A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end month-end Contract Acquisition Costs In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained, for example, sales commission. The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of Topic 606, the Company did not capitalize any contract acquisition cost.
