Earnings Per Share [Abstract]
Earnings per share	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 six months ended June 30, 2021 and 2020: Three months ended June 30, 2021 2020 Numerator: Net income (loss) $ 4,780 $ (24,122 ) Denominator: Basic 9,357,153 9,249,184 Dilutive options 9,498 Diluted 9,366,651 9,249,184 Earnings per share: Basic $ 0.51 $ (2.61 ) Diluted $ 0.51 $ (2.61 ) Six months ended June 30, 2021 2020 Numerator: Net income (loss) $ 7,840 $ (23,489 ) Denominator: Basic 9,349,266 9,236,314 Dilutive options 4,895 Diluted 9,354,161 9,236,314 Earnings per share: Basic $ 0.84 $ (2.54 ) Diluted $ 0.84 $ (2.54 ) For the three and six months ended June 30, 2021 there were 37,200 and 93,935 outstanding stock options, respectively, that were excluded from the dilutive earnings per share calculation because their effect was antidilutive.

Non-homogeneous • 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. Homogeneous loans not meeting the criteria above are considered pass rated loans and evaluated based on delinquency performance. The following tables present the major classifications 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 June 30, 2021 and December 31, 2020: June 30, 2021 Pass Special Substandard Doubtful Total Commercial $ 193,190 $ 2,763 $ 1,334 $ $ 197,287 Real estate: Construction 47,732 7,768 55,500 Commercial 450,523 26,162 25,786 502,471 Residential 183,751 1,122 2,606 187,479 Consumer 6,003 6,003 Total $ 881,199 $ 30,047 $ 37,494 $ $ 948,740 December 31, 2020 Pass Special Substandard Doubtful Total Commercial $ 353,758 $ 3,147 $ 2,175 $ $ 359,080 Real estate: Construction 63,838 1,817 7,747 73,402 Commercial 451,190 29,180 22,125 502,495 Residential 191,775 2,670 3,151 197,596 Consumer 6,666 6,666 Total $ 1,067,227 $ 36,814 $ 35,198 $ $ 1,139,239 The following tables present the classes of the loan portfolio summarized by the aging categories of performing loans and nonaccrual loans as of June 30, 2021 and December 31, 2020.

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 restructures that are classified as impaired. Troubled debt restructures totaled $9,295 at June 30, 2021, $9,985 at December 31, 2020 and $9,988 at June 30, 2020. There were no loans modified as troubled debt restructures during the three and six months ended June 30, 2021. There were nine loans modified as troubled debt restructures during the second quarter of 2020 and nine loans modified during the six months ended June 30, 2020 totaling $7,817. During the three and six months ended June 30, 2021, there were no defaults on restructured loans. During the three months ended June 30, 2020, there were no defaults on loans restructured and one default on a restructured loan totaling $368 during the six months ended June 30, 2020.

Fair value estimates

Fair Value Disclosures [Abstract]
Fair value estimates	7. 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. The following methods and assumptions were used by the Company to calculate fair values and related carrying amounts of assets and liabilities measured at fair value on a recurring basis: Investment securities: Interest rate swap hedges Assets and liabilities measured at fair value on a recurring basis at June 30, 2021 and December 31, 2020 are summarized as follows: Fair Value Measurement Using June 30, 2021 Amount Quoted Prices in Significant Significant U.S. Treasury securities $ 9,689 $ 9,689 $ State and Municipals: Taxable 23,213 23,213 Tax-exempt 43,887 43,887 Mortgage-backed securities: U.S. Government agencies 38,090 38,090 U.S. Government-sponsored enterprises 17,945 17,945 Corporate debt obligations 15,224 15,224 Total $ 148,048 $ 9,689 $ 138,359 Interest rate swap hedge $ 545 $ 545 December 31, 2020 Fair Value Measurement Using Amount Quoted Prices in Significant Significant State and municipals: Taxable $ 22,574 $ 22,574 Tax-exempt 18,395 18,395 Mortgage-backed securities: U.S. Government agencies 26,991 26,991 U.S. Government-sponsored enterprises 25,052 25,052 Corporate debt obligations 10,683 10,683 Total $ 103,695 $ 103,695 Interest rate swap hedge $ 172 $ 172 Other real estate owned charge-off. in value are reported as adjustments to the carrying amount and are recorded in noninterest expense.
