Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The First Bancorp, Inc. ("the Company") is a financial holding company that owns all of the common stock of First National Bank ("the Bank"). The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of Management, all adjustments (consisting of normally recurring accruals) considered necessary for a fair presentation have been included. All significant intercompany transactions and balances are eliminated in consolidation. The income reported for the 2020 period is not necessarily indicative of the results that may be expected for the year ending December 31, 2020. For further information, refer to the consolidated financial statements and notes included in the Company's annual report on Form 10-K for the year ended December 31, 2019. Risks and Uncertainties The impact of the coronavirus disease (COVID-19) continues to cause disruption and uncertainty in the local, national, and world economies. To curtail spread of the virus, governments at all levels have encouraged social distancing and many have imposed restrictions on travel and group meetings, and/or mandated shut-downs of all but essential businesses. The pace of re-opening varies across the United States, and certain locations have reimposed restrictions after experiencing increases in infection rates. Much of the unprecedented uncertainty surrounding the duration of the pandemic, its potential economic ramifications, and any government actions to mitigate them initially experienced in the first quarter of 2020 has continued in the second quarter and early stages of the the third quarter. The Company’s business, financial condition and results of operations generally rely upon the ability of the Bank’s borrowers to repay their loans, the value of collateral underlying the Bank’s secured loans, and demand for loans and other products and services the Bank offers, which are highly dependent on the business environment in the Bank’s primary markets where it operates and in the United States as a whole. The Bank's primary market is the State of Maine, which relies upon tourism for a significant percentage of its economic activity. COVID-19 is expected to adversely impact the tourism industry to a greater degree than other industries, however, it remains the case that an assessment of the impact cannot be completed with a high degree of certainty at this time. In addition to loans, demand for other products and services could be impacted by COVID-19. Depositors and other funding sources may be unwilling to renew certificates of deposit or other types of funding, or may only be willing to do so on terms, including higher interest rates, that are materially less favorable than the Bank has experienced in the recent past. Certain fee based activities such as service charges, interchange revenues, and wealth management activity, could be impacted due to lower activity or market declines. Accordingly, while management expects this matter to likely have a negative financial impact on the Company's financial position and results of future operations, such potential impact cannot be reasonably estimated as of the date of this report, August 7, 2020. Subsequent Events Events occurring subsequent to June 30, 2020, have been evaluated as to their potential impact to the financial statements.

This compares to securities with a fair value of $214,173,000 as of December 31, 2019 and $190,725,000 at June 30, 2019, pledged for the same purposes. Gains and losses on the sale of securities are computed by subtracting the amortized cost at the time of sale from the security's selling price, net of accrued interest to be received. The following table shows securities gains and losses for the six months ended June 30, 2020 and 2019: For the six months ended June 30, For the quarter ended June 30, 2020 2019 2020 2019 Proceeds from sales of securities $ 79,469,000 $ — $ 10,849,000 $ — Gross realized gains 1,526,000 — 428,000 — Gross realized losses (347,000) — (1,000) — Net gain $ 1,179,000 $ — $ 427,000 $ — Related income taxes $ 248,000 $ — $ 90,000 $ — Sales include 28 municipal securities sold in the second quarter of 2020 that had been designated as Held to Maturity. Proceeds from these sales totaled $8,600,000 against a cumulative book value of $8,313,000 resulting in a net realized gain of $268,000. The economic potential impact of COVID-19 is considered to be an isolated and unusual event that could not be reasonably anticipated as outlined in Accounting Standards Codification (ASC) Section 320-10-25. Management conducted a review of its municipal bond portfolio in conjunction with risk mitigation efforts related to the onset of the COVID-19 virus; the intent of the review was to identify investment exposures with lower relative credit ratings, locales with perceived above average economic risk, municipal entities with reliance upon sales tax or income tax revenue, or any combination of these factors. Each of the sold positions met one or more of the criteria. Management reviews securities with unrealized losses for other than temporary impairment. As of June 30, 2020, there were 52 securities with unrealized losses held in the Company's portfolio. These securities were temporarily impaired as a result of changes in interest rates reducing their fair value, of which 11 had been temporarily impaired for 12 months or more. The Company has the ability and intent to hold its impaired securities until a recovery of their amortized cost, which may be at maturity. Information regarding securities temporarily impaired as of June 30, 2020 is summarized below: Less than 12 months 12 months or more Total Fair Value (Estimated) Unrealized Losses Fair Value (Estimated) Unrealized Losses Fair Value (Estimated) Unrealized Losses U.S. Government-sponsored agencies $ 7,988,000 $ (12,000) $ — $ — $ 7,988,000 $ (12,000) Mortgage-backed securities 28,116,000 (160,000) 4,771,000 (143,000) 32,887,000 (303,000) State and political subdivisions 7,623,000 (32,000) — — 7,623,000 (32,000) $ 43,727,000 $ (204,000) $ 4,771,000 $ (143,000) $ 48,498,000 $ (347,000) As of December 31, 2019, there were 86 securities with unrealized losses held in the Company's portfolio.

These securities were temporarily impaired as a result of changes in interest rates reducing their fair value, of which 127 had been temporarily impaired for 12 months or more. In the first quarter of 2019, one issuer of securities held in the portfolio was downgraded by a rating agency to less than investment grade. These securities totaled approximately 0.06% of overall state and municipal security holdings and were subsequently sold during the third quarter 2019.

The net unrealized loss, net of taxes, on these securities at the date of the transfer was $15,000. The net unrealized holding loss at the time of transfer continues to be reported in accumulated other comprehensive income (loss), net of tax and is amortized over the remaining lives of the securities as an adjustment of the yield. The amortization of the net unrealized loss reported in accumulated other comprehensive income (loss) will offset the effect on interest income of the discount for the transferred securities. The remaining unamortized balance of the net unrealized losses for the securities transferred from available for sale to held to maturity was $146,000, net of tax, at June 30, 2020. This compares to $182,000 and $190,000, net of taxes, at December 31, 2019 and June 30, 2019, respectively. These securities were transferred as a part of the Company's overall investment and balance sheet strategies. The Bank is a member of the Federal Home Loan Bank ("FHLB") of Boston, a cooperatively owned wholesale bank for housing and finance in the six New England States. As a requirement of membership in the FHLB, the Bank must own a minimum required amount of FHLB stock, calculated periodically based primarily on its level of borrowings from the FHLB. The Bank uses the FHLB for a portion of its wholesale funding needs. As of June 30, 2020 and 2019, and December 31, 2019, the Bank's investment in FHLB stock totaled $9,508,000, $7,945,000 and $7,945,000, respectively. FHLB stock is a non-marketable equity security and therefore is reported at cost, which equals par value. The Company periodically evaluates its investment in FHLB stock for impairment based on, among other factors, the capital adequacy of the FHLB and its overall financial condition. No impairment losses have been recorded through June 30, 2020. The Company will continue to monitor its investment in FHLB stock.

The decrease in net deferred loan costs year-over-year and year-to-date is attributable to PPP loans originated during the second quarter of 2020. These loans generated gross origination fee income of $3,730,000 and deferred loan costs of $283,000; during the quarter a net of $356,000 was recognized in interest income. Pursuant to collateral agreements, qualifying first mortgage loans and commercial real estate loans, which totaled $399,525,000 at June 30, 2020, were used to collateralize borrowings from the FHLB. This compares to qualifying loans which totaled $296,871,000 at December 31, 2019, and $312,568,000 at June 30, 2019. In addition, commercial, construction and home equity loans totaling $264,343,000 at June 30, 2020, $240,133,000 at December 31, 2019, and $239,481,000 at June 30, 2019, were used to collateralize a standby line of credit at the Federal Reserve Bank of Boston. For all loan classes, loans over 30 days past due are considered delinquent.

Both the Interagency Statement and the CARES Act provided an exemption for qualified modifications from Troubled Debt Restructure (TDR) designation. The Company actively worked with borrowers impacted by the COVID-19 outbreak and as of June 30, 2020 a total of 867 loan modification requests had been completed in conformance with the Interagency Statement issued in March, representing $239,484,000 in loan balances, or approximately 16.5% of the overall loan portfolio. These loans have not been classified as TDRs and are not included as past due in any loan delinquency data so long as the modified terms are met.

A loan is "well secured" if it is secured (1) by collateral in the form of liens on or pledges of real or personal property, including securities, that have a realizable value sufficient to discharge the debt (including accrued interest) in full, or (2) by the guarantee of a financially responsible party. A loan is "in the process of collection" if collection of the loan is proceeding in due course either (1) through legal action, including judgment enforcement procedures, or, (2) in appropriate circumstances, through collection efforts not involving legal action which are reasonably expected to result in repayment of the debt or in its restoration to a current status in the near future. Cash payments received on non-accrual loans, which are included in impaired loans, are applied to reduce the loan's principal balance until the remaining principal balance is deemed collectible, after which interest is recognized when collected. As a general rule, a loan may be restored to accrual status when payments are current for a substantial period of time, generally six months, and repayment of the remaining contractual amounts is expected, or when it otherwise becomes well secured and in the process of collection. Information on nonaccrual loans as of June 30, 2020 and 2019 and at December 31, 2019 is presented in the following table: June 30, 2020 December 31, 2019 June 30, 2019 Commercial Real estate $ 1,245,000 $ 1,784,000 $ 1,532,000 Construction 232,000 256,000 261,000 Other 323,000 6,534,000 7,014,000 Municipal — — — Residential Term 4,685,000 5,899,000 5,892,000 Construction — — — Home equity line of credit 1,854,000 2,171,000 694,000 Consumer 5,000 5,000 — Total $ 8,344,000 $ 16,649,000 $ 15,393,000 Impaired loans include troubled debt restructured ("TDR") and loans placed on non-accrual. These loans are measured at the present value of expected future cash flows discounted at the loan's effective interest rate or at the fair value of the collateral if the loan is collateral dependent. If the measure of an impaired loan is lower than the recorded investment in the loan and estimated selling costs, a specific reserve is established for the difference, or, in certain situations, if the measure of an impaired loan is lower than the recorded investment in the loan and estimated selling costs, the difference is written off.

To determine whether or not a loan should be classified as a TDR, Management evaluates a loan based upon the following criteria: • The borrower demonstrates financial difficulty; common indicators include past due status with bank obligations, substandard credit bureau reports, or an inability to refinance with another lender, and • The Company has granted a concession; common concession types include maturity date extension, interest rate adjustments to below market pricing, and deferment of payments. As of June 30, 2020, the Company had 78 loans with a balance of $14,013,000 that have been classified as TDRs. This compares to 81 loans with a balance of $21,424,000 and 83 loans with a balance of $24,454,000 classified as TDRs as of December 31, 2019 and June 30, 2019, respectively. The impairment carried as a specific reserve in the allowance for loan losses is calculated by present valuing the expected cash flows on the loan at the original interest rate, or, for collateral-dependent loans, using the fair value of the collateral less costs to sell.

Receivables [Abstract]
Allowance for Loan Losses	Allowance for Loan Losses The Company provides for loan losses through the establishment of an allowance for loan losses which represents an estimated reserve for existing losses in the loan portfolio. A systematic methodology is used for determining the allowance that includes a quarterly review process, risk rating changes, and adjustments to the allowance. The loan portfolio is classified in eight classes and credit risk is evaluated separately in each class. Major risk characteristics relevant to each portfolio segment are as follows: Commercial Real Estate - Commercial real estate loans are impacted by factors such as competitive market forces, vacancy rates, cap rates, net operating incomes, lease renewals and overall economic demand. In addition, loans in the recreational and tourism sector can be affected by weather conditions, such as unseasonably low winter snowfalls. Commercial real estate lending also carries a higher degree of environmental risk than other real estate lending. Commercial Construction - Commercial construction loans are impacted by factors similar to those for commercial real estate loans in addition to risks related to contractor financial capacity and ability to complete a project within acceptable time frames and within budget. Commercial Other - A weakened economy, soft consumer spending, and the rising cost of labor or raw materials are examples of issues that can impact the credit quality in this segment. Municipal Loans - The overall health of the economy, including unemployment rates and housing prices, has an impact on the credit quality of this segment. Residential Real Estate Term - The overall health of the economy, including unemployment rates and housing prices, has an impact on the credit quality of this segment. Residential Real Estate Construction - Residential construction loans are impacted by factors similar to those for residential real estate term loans in addition to risks related to contractor financial capacity and ability to complete a project within acceptable time frames and within budget. Home Equity Line of Credit - The overall health of the economy, including unemployment rates and housing prices, has an impact on the credit quality of this segment. Consumer - The overall health of the economy, including unemployment rates, has an impact on the credit quality of this segment. The appropriate level of the allowance is evaluated continually based on a review of significant loans, with a particular emphasis on nonaccruing, past due, and other loans that may require special attention. Other factors include general conditions in local and national economies; loan portfolio composition and asset quality indicators; and internal factors such as changes in underwriting policies, credit administration practices, experience, ability and depth of lending management, among others. The allowance consists of four elements: (1) specific reserves for loans evaluated individually for impairment; (2) general reserves for each portfolio segment based on historical loan loss experience, (3) qualitative reserves judgmentally adjusted for local and national economic conditions, concentrations, portfolio composition, volume and severity of delinquencies and nonaccrual loans, trends of criticized and classified loans, changes in credit policies and underwriting standards, credit administration practices, and other factors as applicable for each portfolio segment; and (4) unallocated reserves. All outstanding loans are considered in evaluating the appropriateness of the allowance. A breakdown of the allowance for loan losses as of June 30, 2020, December 31, 2019, and June 30, 2019, by class of financing receivable and allowance element, is presented in the following tables: As of June 30, 2020 Specific Reserves on Loans Evaluated Individually for Impairment General Reserves on Loans Based on Historical Loss Experience Reserves for Qualitative Factors Unallocated Total Reserves Commercial Real estate $ 199,000 $ 631,000 $ 3,681,000 $ — $ 4,511,000 Construction 20,000 74,000 430,000 — 524,000 Other 132,000 521,000 3,036,000 — 3,689,000 Municipal — — 110,000 — 110,000 Residential Term 269,000 285,000 1,707,000 — 2,261,000 Construction — 9,000 55,000 — 64,000 Home equity line of credit 292,000 99,000 893,000 — 1,284,000 Consumer 5,000 195,000 458,000 — 658,000 Unallocated — — — 1,009,000 1,009,000 $ 917,000 $ 1,814,000 $ 10,370,000 $ 1,009,000 $ 14,110,000 As of December 31, 2019 Specific Reserves on Loans Evaluated Individually for Impairment General Reserves on Loans Based on Historical Loss Experience Reserves for Qualitative Factors Unallocated Total Reserves Commercial Real estate $ 251,000 $ 729,000 $ 2,762,000 $ — $ 3,742,000 Construction — 76,000 289,000 — 365,000 Other 1,273,000 430,000 1,626,000 — 3,329,000 Municipal — — 27,000 — 27,000 Residential Term 237,000 153,000 634,000 — 1,024,000 Construction — 5,000 20,000 — 25,000 Home equity line of credit 447,000 130,000 501,000 — 1,078,000 Consumer 5,000 460,000 402,000 — 867,000 Unallocated — — — 1,182,000 1,182,000 $ 2,213,000 $ 1,983,000 $ 6,261,000 $ 1,182,000 $ 11,639,000 As of June 30, 2019 Specific Reserves on Loans Evaluated Individually for Impairment General Reserves on Loans Based on Historical Loss Experience Reserves for Qualitative Factors Unallocated Total Reserves Commercial Real estate $ 196,000 $ 789,000 $ 2,624,000 $ — $ 3,609,000 Construction — 72,000 237,000 — 309,000 Other 1,320,000 457,000 1,504,000 — 3,281,000 Municipal — — 25,000 — 25,000 Residential Term 305,000 197,000 604,000 — 1,106,000 Construction — 6,000 17,000 — 23,000 Home equity line of credit 9,000 156,000 468,000 — 633,000 Consumer — 279,000 370,000 — 649,000 Unallocated — — — 1,836,000 1,836,000 $ 1,830,000 $ 1,956,000 $ 5,849,000 $ 1,836,000 $ 11,471,000 Qualitative adjustment factors are taken into consideration when determining reserve estimates. These adjustment factors are based upon Management's evaluation of various current conditions, including those listed below. • General economic conditions. • Credit quality trends with emphasis on loan delinquencies, nonaccrual levels and classified loans. • Recent loss experience in particular segments of the portfolio. • Loan volumes and concentrations, including changes in mix. • Other factors, including changes in quality of the loan origination; loan policy changes; changes in credit risk management processes; Bank regulatory and external loan review examination results. Qualitative factors applied to the portfolio or segments of the portfolio may include judgments concerning general economic conditions that may affect credit quality, credit concentrations, the pace of portfolio growth, the direction of risk rating movements, policy exception levels, and delinquency levels; these qualitative factors are also considered in connection with the unallocated portion of our allowance for loan losses. The qualitative portion of the allowance for loan losses was 0.71% of related loans as of June 30, 2020, compared to 0.48% of related loans as of December 31, 2019. The qualitative portion increased $4,109,000 between December 31, 2019 and June 30, 2020 due to a mix of factors. These included initial impacts of the COVID-19 pandemic on various macroeconomic measures used in the qualitative model, as well as top down and unit level analysis of the loan portfolio for factors such as COVID-19 related modifications and industry segments particularly vulnerable to social distancing. The unallocated component of the allowance totaled $1,009,000 at June 30, 2020, or 7.2% of the total reserve. This compares to $1,182,000 or 10.2% as of December 31, 2019. While year to date growth in the qualitative portion of the reserve directionally reflects potential impacts of COVID-19 on the loan portfolio, it remains likely that there are other underlying credit risks not yet captured in loan specific or qualitative metrics the Company uses to estimate its allowance. This uncertainty along with general imprecision related to portfolio growth supports the continued inclusion of an unallocated component. The allowance for loan losses as a percent of total loans stood at 0.97% as of June 30, 2020, 0.90% at December 31, 2019 and 0.92% as of June 30, 2019. Commercial loans are comprised of three major classes, commercial real estate loans, commercial construction loans and other commercial loans. Commercial real estate loans consist of mortgage loans to finance investments in real property such as multi-family residential, commercial/retail, office, industrial, hotels, educational and other specific or mixed use properties. Commercial real estate loans are typically written with amortizing payment structures. Collateral values are determined based on appraisals and evaluations in accordance with established policy and regulatory guidelines. Commercial real estate loans typically have a loan-to-value ratio of up to 80% based upon current valuation information at the time the loan is made. Commercial real estate loans are primarily paid by the cash flow generated from the real property, such as operating leases, rents, or other operating cash flows from the borrower. Commercial construction loans consist of loans to finance construction in a mix of owner- and non-owner occupied commercial real estate properties. Commercial construction loans typically have maturities of less than two years. Payment structures during the construction period are typically on an interest only basis, although principal payments may be established depending on the type of construction project being financed. During the construction phase, commercial construction loans are primarily paid by cash flow generated from the construction project or other operating cash flows from the borrower or guarantors, if applicable. At the end of the construction period, loan repayment typically comes from a third party source in the event that the Company will not be providing permanent term financing. Collateral valuation and loan-to-value guidelines follow those for commercial real estate loans. Other commercial loans consist of revolving and term loan obligations extended to business and corporate enterprises for the purpose of financing working capital and or capital investment. Collateral generally consists of pledges of business assets including, but not limited to, accounts receivable, inventory, plant and equipment, and/or real estate, if applicable. Commercial loans are primarily paid by the operating cash flow of the borrower. Commercial loans may be secured or unsecured. Municipal loans are comprised of loans to municipalities in Maine for capitalized expenditures, construction projects or tax anticipation notes. All municipal loans are considered general obligations of the municipality and are collateralized by the taxing ability of the municipality for repayment of debt. Residential loans are comprised of two classes: term loans and construction loans. Residential term loans consist of residential real estate loans held in the Company's loan portfolio made to borrowers who demonstrate the ability to make scheduled payments with full consideration to underwriting factors. Borrower qualifications include favorable credit history combined with supportive income requirements and loan-to-value ratios within established policy and regulatory guidelines. Collateral values are determined based on appraisals and evaluations in accordance with established policy and regulatory guidelines. Residential loans typically have a loan-to-value ratio of up to 80% based on appraisal information at the time the loan is made. Collateral consists of mortgage liens on one- to four-family residential properties. Loans are offered with fixed or adjustable rates with amortization terms of up to thirty years. Residential construction loans typically consist of loans for the purpose of constructing single family residences to be owned and occupied by the borrower. Borrower qualifications include favorable credit history combined with supportive income requirements and loan-to-value ratios within established policy and regulatory guidelines. Residential construction loans normally have construction terms of one year or less and payment during the construction term is typically on an interest only basis from sources including interest reserves, borrower liquidity and/or income. Residential construction loans will typically convert to permanent financing from the Company or have another financing commitment in place from an acceptable mortgage lender. Collateral valuation and loan-to-value guidelines are consistent with those for residential term loans. Home equity lines of credit are made to qualified individuals and are secured by senior or junior mortgage liens on owner occupied one- to four-family homes, condominiums, or vacation homes. The home equity line of credit typically has a variable interest rate and is billed as interest-only payments during the draw period. At the end of the draw period, the home equity line of credit is billed as a percentage of the principal balance plus all accrued interest. Loan maturities are normally 300 months. Borrower qualifications include favorable credit history combined with supportive income requirements and combined loan-to- value ratios usually not exceeding 80% inclusive of priority liens. Collateral valuation guidelines follow those for residential real estate loans. Consumer loan products including personal lines of credit and amortizing loans made to qualified individuals for various purposes such as auto, recreational vehicles, debt consolidation, personal expenses or overdraft protection. Borrower qualifications include favorable credit history combined with supportive income and collateral requirements within established policy guidelines. Consumer loans may be secured or unsecured. Construction, land and land development loans, both commercial and residential, comprise a small portion of the portfolio, and at 31.1% of capital are below the regulatory guidance limit of 100.0% of capital at June 30, 2020. Construction loans and non-owner-occupied commercial real estate loans are at 125.8% of total capital, below the regulatory limit of 300.0% of capital at June 30, 2020. The process of establishing the allowance with respect to the commercial loan portfolio begins when a Loan Officer or Senior Officer (or designate) initially assigns each loan a risk rating, using established credit criteria. Approximately 60% of a trailing four quarter average gross commercial portfolio is subject to review and validation annually by an independent consulting firm. Additionally, commercial loan relationships with exposure greater than or equal to $500,000 are subject to review annually by the Company's internal credit review function. The methodology employs Management's judgment as to the level of losses on existing loans based on internal review of the loan portfolio, including an analysis of a borrower's current financial position, and the consideration of current and anticipated economic conditions and their potential effects on specific borrowers and or lines of business. In determining the Company's ability to collect certain loans, Management also considers the fair value of underlying collateral. The risk rating system has eight levels, defined as follows: 1 Strong Credits rated "1" are characterized by borrowers fully responsible for the credit with excellent capacity to pay principal and interest. Loans rated "1" may be secured with acceptable forms of liquid collateral. 2 Above Average Credits rated "2" are characterized by borrowers that have better than average liquidity, capitalization, earnings and/or cash flow with a consistent record of solid financial performance. 3 Satisfactory Credits rated "3" are characterized by borrowers with favorable liquidity, profitability and financial condition with adequate cash flow to pay debt service. 4 Average Credits rated "4" are characterized by borrowers that present risk more than 1, 2 and 3 rated loans and merit an ordinary level of ongoing monitoring. Financial condition is on par or somewhat below industry averages while cash flow is generally adequate to meet debt service requirements. 5 Watch Credits rated "5" are characterized by borrowers that warrant greater monitoring due to financial condition or unresolved and identified risk factors. 6 Other Assets Especially Mentioned (OAEM) Loans in this category are currently protected but are potentially weak and constitute an undue and unwarranted credit risk, but not to the point of justifying a classification of substandard. OAEM have potential weaknesses which may, if not checked or corrected, weaken the asset or inadequately protect the Company's credit position at some future date. 7 Substandard Loans in this category are inadequately protected by the paying capacity of the borrower or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Substandard loans are characterized by the distinct possibility that the Company may sustain some loss if the deficiencies are not corrected. 8 Doubtful Loans classified "Doubtful" have the same weaknesses as those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is high, but because of certain important and reasonably specific pending factors which may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined.

This determination is based on circumstances specific to a borrower including repayment ability, analysis of collateral and other factors as applicable. Residential loans are comprised of two classes: term loans, which include traditional amortizing home mortgages, and construction loans, which include loans for owner-occupied residential construction. Residential loans typically have a 75% to 80% loan to value based upon current appraisal information at the time the loan is made. Home equity loans and lines of credit are typically written to the same underwriting standards. Consumer loans are primarily amortizing loans to individuals collateralized by automobiles, pleasure craft and recreation vehicles, typically with a maximum loan to value of 80% to 90% of the purchase price of the collateral. Consumer loans also include a small amount of unsecured short-term time notes to individuals. Residential loans, consumer loans and home equity lines of credit are segregated into homogeneous pools with similar risk characteristics. Trends and current conditions are analyzed and historical loss experience is adjusted accordingly. Quantitative and qualitative adjustment factors for these segments are consistent with those for the commercial and municipal classes. Certain loans in the residential, home equity lines of credit and consumer classes identified as having the potential for further deterioration are analyzed individually to confirm impairment status, and to determine the need for a specific reserve; however there is no formal rating system used for these classes. Consumer loans greater than 120 days past due are generally charged off. Residential loans 90 days or more past due are placed on non-accrual status unless the loans are both well secured and in the process of collection. One- to four-family residential real estate loans and home equity loans are written down or charged-off no later than 180 days past due, or for residential real estate secured loans having a borrower in bankruptcy, within 60 days of receipt of notification of filing from the bankruptcy court, whichever is sooner. This is subject to completion of a current assessment of the value of the collateral with any outstanding loan balance in excess of the fair value of the property, less costs to sell, written down or charged-off.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation At the 2010 Annual Meeting, shareholders approved the 2010 Equity Incentive Plan (the "2010 Plan"). This reserved 400,000 shares of common stock for issuance in connection with stock options, restricted stock awards and other equity based awards to attract and retain the best available personnel, provide additional incentive to officers, employees and non-employee Directors and promote the success of the Company. Such grants and awards were structured in a manner that did not encourage the recipients to expose the Company to undue or inappropriate risk. Options issued under the 2010 Plan qualified for treatment as incentive stock options for purposes of Section 422 of the Internal Revenue Code. Other compensation under the 2010 Plan qualified as performance-based for purposes of Section 162(m) of the Internal Revenue Code, and satisfied NASDAQ guidelines relating to equity compensation. The 2010 Plan expired on April 28, 2020, leaving 215,513 shares not issued. At the 2020 Annual Meeting, shareholders approved the 2020 Equity Incentive Plan (the "2020 Plan"). This reserves 400,000 shares of common stock for issuance in connection with stock options, restricted stock awards and other equity based awards to attract and retain the best available personnel, provide additional incentive to officers, employees and non-employee Directors and promote the success of the Company. Such grants and awards will be structured in a manner that does not encourage the recipients to expose the Company to undue or inappropriate risk. Options issued under the 2020 Plan qualify for treatment as incentive stock options for purposes of Section 422 of the Internal Revenue Code. Other compensation under the 2020 Plan will qualify as performance-based for purposes of Section 162(m) of the Internal Revenue Code, and will satisfy NASDAQ guidelines relating to equity compensation.

Retirement Benefits, Description [Abstract]
Employee Benefit Plans	Employee Benefit Plans 401(k) Plan The Bank has a defined contribution plan available to substantially all employees who have completed 3 months of service. Employees may contribute up to Internal Revenue Service ("IRS") determined limits and the Bank may match employee contributions not to exceed 3.0% of compensation depending on contribution level. Subject to a vote of the Board of Directors, the Bank may also make a profit-sharing contribution to the Plan. Such contribution equaled 2.0% of each eligible employee's compensation in 2019. The Company adopted the safe harbor form of 401(k) plan for 2020 and will follow safe harbor guidelines when determining the level of discretionary contribution. The expense related to the 401(k) plan was $453,000 and $322,000 for the six months ended June 30, 2020 and 2019, respectively. Deferred Compensation and Supplemental Retirement Benefits The Bank also provides unfunded supplemental retirement benefits for certain officers, payable in installments over 20 years upon retirement or death. The agreements consist of individual contracts with differing characteristics that, when taken together, do not constitute a postretirement plan. The costs for these benefits are recognized over the service periods of the participating officers in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 712 "Compensation – Nonretirement Postemployment Benefits". The expense of these supplemental retirement benefits was $79,000 for the six months ended June 30, 2020 and 2019. As of June 30, 2020, the associated accrued liability included in other liabilities in the balance sheet was $2,764,000 compared to $2,828,000 and $2,887,000 at December 31, 2019 and June 30, 2019, respectively. Post-Retirement Benefit Plans The Bank sponsors two post-retirement benefit plans. One plan currently provides a subsidy for health insurance premiums to certain retired employees and a future subsidy for six active employees who were age 50 and over in 1996. These subsidies are based on years of service and range between $40 and $1,200 per month per person. The other plan provides life insurance coverage to certain retired employees and health insurance for retired directors. None of these plans are pre-funded. The Company utilizes FASB ASC Topic 712 to recognize the overfunded or underfunded status of a defined benefit postretirement plan as an asset or liability in its balance sheet and to recognize changes in the funded status in the year in which the changes occur through comprehensive income (loss). The following table sets forth the accumulated postretirement benefit obligation and funded status: At or for the six months ended June 30, 2020 2019 Change in benefit obligation Benefit obligation at beginning of year $ 1,581,000 $ 1,599,000 Interest cost 32,000 33,000 Benefits paid (54,000) (56,000) Benefit obligation at end of period $ 1,559,000 $ 1,576,000 Funded status Benefit obligation at end of period $ (1,559,000) $ (1,576,000) Unamortized gain (31,000) (47,000) Accrued benefit cost at end of period $ (1,590,000) $ (1,623,000) The following table sets forth the net periodic pension cost: For the six months ended June 30, For the quarter ended June 30, 2020 2019 2020 2019 Components of net periodic benefit cost Interest cost $ 32,000 $ 33,000 $ 16,000 $ 17,000 Net periodic benefit cost $ 32,000 $ 33,000 $ 16,000 $ 17,000 Amounts not yet reflected in net periodic benefit cost and included in accumulated other comprehensive income are as follows: June 30, December 31, 2019 June 30, Unamortized net actuarial gain $ 31,000 $ 31,000 $ 47,000 Deferred tax expense (7,000) (7,000) (10,000) Net unrecognized postretirement benefits included in accumulated other comprehensive income $ 24,000 $ 24,000 $ 37,000 A weighted average discount rate of 3.00% was used in determining the accumulated benefit obligation and the net periodic benefit cost. The assumed health care cost trend rate is 7.0%. The measurement date for benefit obligations was as of year-end for prior years presented. The expected benefit payments for all of 2020 are $108,000. Plan expense for 2020 is estimated to be $64,000. A 1% change in trend assumptions would create an approximate change in the same direction of $100,000 in the accumulated benefit obligation, $7,000 in the interest cost and $1,000 in the service cost.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Derivative Instruments	Financial Derivative Instruments The Bank uses derivative financial instruments for risk management purposes and not for trading or speculative purposes. As part of its overall asset and liability management strategy, the Bank periodically uses derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. The Bank’s interest rate risk management strategy involves modifying the re-pricing characteristics of certain assets or liabilities so that changes in interest rates do not have a significant effect on net interest income. The Bank recognizes its derivative instruments in the consolidated balance sheet at fair value. On the date the derivative instrument is entered into, the Bank designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Bank formally documents relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedge transactions. The Bank also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items. Changes in fair value of derivative instruments that are highly effective and qualify as cash flow hedges are recorded in other comprehensive income or loss. Any ineffective portion is recorded in earnings. The Bank discontinues hedge accounting when it is determined that the derivative is no longer highly effective in offsetting changes of the hedged risk on the hedged item, or management determines that the designation of the derivative as a hedging instrument is no longer appropriate. The details of the interest rate swap agreements are as follows: June 30, 2020 December 31, 2019 June 30, 2019 Effective Date Maturity Date Variable Index Received Fixed Rate Paid Presentation on Consolidated Balance Sheet Notional Amount Fair Value Notional Amount Fair Value Notional Amount Fair Value 06/05/2018 12/05/2019 1-Month USD LIBOR 2.466 % Other Liabilities $ — $ — $ — $ — $ 25,000,000 $ (45,000) 06/27/2016 06/27/2021 1-Month USD LIBOR 0.893 % Other (Liabilities) Assets 20,000,000 (150,000) 20,000,000 199,000 20,000,000 300,000 06/28/2016 06/28/2021 1-Month USD LIBOR 0.940 % Other (Liabilities) Assets 30,000,000 (238,000) 30,000,000 278,000 30,000,000 423,000 06/05/2018 06/05/2020 1-Month USD LIBOR 2.547 % Other Liabilities — — 25,000,000 (96,000) 25,000,000 (160,000) 06/05/2018 12/05/2020 1-Month USD LIBOR 2.603 % Other Liabilities — — 25,000,000 (234,000) 25,000,000 (313,000) 12/05/2019 12/05/2022 3-Month USD LIBOR 1.779 % Other Liabilities — — 25,000,000 (98,000) 25,000,000 (110,000) 08/02/2019 08/02/2024 1-Month USD LIBOR 1.590 % Other Liabilities 12,500,000 (736,000) 12,500,000 (11,000) — — 08/05/2019 08/05/2024 1-Month USD LIBOR 1.420 % Other (Liabilities) Assets 12,500,000 (649,000) 12,500,000 85,000 — — 02/12/2020 02/12/2023 3-Month USD LIBOR 1.486 % Other Liabilities 25,000,000 (841,000) — — — — 02/12/2020 02/12/2024 3-Month USD LIBOR 1.477 % Other Liabilities 25,000,000 (1,124,000) — — — — 06/28/2021 06/28/2026 1-Month USD LIBOR 1.158 % Other Liabilities 50,000,000 (2,119,000) — — — — 03/13/2020 03/13/2025 3-Month USD LIBOR 0.855 % Other Liabilities 25,000,000 (659,000) — — — — 03/13/2020 03/13/2030 3-Month USD LIBOR 1.029 % Other Liabilities 20,000,000 (811,000) — — — — 04/07/2020 04/07/2023 3-Month USD Libor 0.599 % Other Liabilities 20,000,000 (210,000) — — — — 04/07/2020 04/07/2024 3-Month USD Libor 0.643 % Other Liabilities 20,000,000 (295,000) — — — — $ 260,000,000 $ (7,832,000) $ 150,000,000 $ 123,000 $ 150,000,000 $ 95,000 During the first quarter of 2020, the Bank took advantage of market opportunities to restructure several interest rate swap positions and extend funding at favorable interest rates; one-time charges totaling $1.76 million were incurred and expensed in the first quarter of 2020 in connection with the restructuring. The Company would reclassify unrealized gains or losses accounted for within accumulated other comprehensive income (loss) into earnings if the interest rate swaps were to become ineffective or the swaps were to terminate. In the next 12 months, the Company does not believe it will be required to reclassify any unrealized gains or losses accounted for within accumulated other comprehensive income (loss) into earnings as a result of ineffectiveness or swap termination. Amounts paid or received under the swaps are reported in interest expense in the consolidated statement of income, and in interest paid in the consolidated statement of cash flows. Customer loan derivatives The Bank will enter into interest rate swaps with qualified commercial customers. Through these arrangements, the Bank is able to provide a means for a loan customer to obtain a long-term fixed rate, while it simultaneously contracts with an approved, highly-rated, third-party financial institution as counterparty to swap the fixed rate for a variable rate. Such loan level arrangements are not designated as hedges for accounting purposes, and are recorded at fair value in the Company’s consolidated balance sheet. At June 30, 2020 there were three customer loan swap arrangements in place, detailed below: June 30, 2020 December 31, 2019 June 30, 2019 Presentation on Consolidated Balance Sheet Number of Positions Notional Amount Fair Value Number of Positions Notional Amount Fair Value Number of Positions Notional Amount Fair Value Pay Fixed, Receive Variable Other Liabilities 3 $ 24,921,000 $ (3,613,000) 2 $ 16,374,000 $ (1,205,000) 1 $ 12,914,000 $ 991,000 Receive Fixed, Pay Variable Other Assets 3 24,921,000 3,613,000 2 16,374,000 1,205,000 1 12,904,000 (991,000) Total 6 $ 49,842,000 $ — 4 $ 32,748,000 $ — 2 $ 25,818,000 $ — Derivative collateral The Bank has entered into a master netting arrangement with its counterparty and settles payments with the counterparty as necessary. The Bank's arrangement with its institutional counterparty requires it to post cash or other assets as collateral for its various loan swap contracts in a net liability position based on their fair values and the Bank's credit rating or receive cash collateral for contracts in a net asset position as requested. At June 30, 2020, the Bank posted to the counterparty $3,100,000 of cash and $10,000,000 in securities as collateral on its swap contracts. The required amount to be pledged was $9,322,000. Cessation of LIBOR The Company is aware that LIBOR may no longer be published after December 31, 2021. The Federal Reserve formed the Alternative Reference Rates Committee (ARRC) to guide the transition process in the United States. ARRC has issued a number of recommendations including the adoption of the Secured Overnight Financing Rate (SOFR) as a replacement for LIBOR. The International Swap and Derivatives Association (ISDA), the organization that oversees and guides swap and derivatives markets and participants, continues to work on transitions and replacement rates, including having replacement rates in place before the possible cessation of LIBOR at the end of 2021, and has committed to providing more definitive recommendations later in 2020. The Company has formed a working group to address the change away from LIBOR. Management intends to continue to monitor developments from ARRC and ISDA closely, and expects to pursue the steps ultimately recommended to provide for an orderly transition to a post-LIBOR environment. Of the interest rate swap contracts the Bank has in place as of June 30, 2020, two contracts carrying a total notional amount of $50 million are set to mature prior to December 31, 2021; nine contracts with a total notional amount of $210 million have maturity dates beyond December 31, 2021. The three customer loan swap contracts shown in the table immediately above have maturity dates of December 19, 2029, July 1, 2035 and October 1, 2039.

The Company's servicing assets and servicing liabilities are reported using the amortization method and carried at the lower of amortized cost or fair value by strata. In evaluating the carrying values of mortgage servicing rights, the Company obtains third party valuations based on loan level data including note rate, type and term of the underlying loans. The model utilizes several assumptions, the most significant of which is loan prepayments, calculated using a three For the six months ended June 30, 2020 and 2019, servicing rights capitalized totaled $464,000 and $128,000, respectively. Servicing rights amortized for the six-month periods ended June 30, 2020 and 2019 were $135,000 and $114,000, respectively. The fair value of servicing rights was $1,777,000, $2,089,000 and $2,087,000 at June 30, 2020, December 31, 2019 and June 30, 2019, respectively.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Certain assets and liabilities are recorded at fair value to provide additional insight into the Company's quality of earnings. Some of these assets and liabilities are measured on a recurring basis while others are measured on a nonrecurring basis, with the determination based upon applicable existing accounting pronouncements. For example, securities available for sale are recorded at fair value on a recurring basis. Other assets, such as, other real estate owned and impaired loans, are recorded at fair value on a nonrecurring basis using the lower of cost or market methodology to determine impairment of individual assets. The Company groups assets and liabilities which are recorded at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement (with level 1 considered highest and level 3 considered lowest). A brief description of each level follows: Level 1 - Valuation is based upon quoted prices for identical instruments in active markets. Level 2 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 - Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates that market participants would use in pricing the asset or liability. Valuation includes use of discounted cash flow models and similar techniques. The fair value methods and assumptions for the Company's financial instruments and other assets measured at fair value are set forth below. Investment Securities The fair values of investment securities are estimated by independent providers using a market approach with observable inputs, including matrix pricing and recent transactions. In obtaining such valuation information from third parties, the Company has evaluated their valuation methodologies used to develop the fair values in order to determine whether the valuations are representative of an exit price in the Company's principal markets. The Company's principal markets for its securities portfolios are the secondary institutional markets, with an exit price that is predominantly reflective of bid level pricing in those markets. Fair values are calculated based on the value of one unit without regard to any premium or discount that may result from concentrations of ownership of a financial instrument, possible tax ramifications, or estimated transaction costs. If these considerations had been incorporated into the fair value estimates, the aggregate fair value could have been changed. Loans Fair values are estimated for portfolios of loans based on exit pricing notion. The fair values of performing loans are calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest risk inherent in the loan. The estimates of maturity are based on the Company's historical experience with repayments for each loan classification, modified, as required, by an estimate of the effect of current economic and lending conditions, and the effects of estimated prepayments. Assumptions regarding credit risk, cash flows, and discount rates are judgmentally determined using available market information and specific borrower information. Management has made estimates of fair value using discount rates that it believes to be reasonable. However, because there is no market for many of these financial instruments, Management has no basis to determine whether the fair value presented above would be indicative of the value negotiated in an actual sale. As such, the Company classifies loans as Level 3, except for certain collateral-dependent impaired loans. Fair values of impaired loans are based on estimated cash flows and are discounted using a rate commensurate with the risk associated with the estimated cash flows, or if collateral dependent, discounted to the appraised value of the collateral as determined by reference to sale prices of similar properties, less costs to sell. As such, the Company classifies collateral dependent impaired loans for which a specific reserve results in a fair value measure as Level 2. All other impaired loans are classified as Level 3. Other Real Estate Owned Real estate acquired through foreclosure is initially recorded at fair value. The fair value of other real estate owned is based on property appraisals and an analysis of similar properties currently available. As such, the Company records other real estate owned as nonrecurring Level 2. Mortgage Servicing Rights Mortgage servicing rights represent the value associated with servicing residential mortgage loans. Servicing assets and servicing liabilities are reported using the amortization method and compared to fair value for impairment. In evaluating the fair values of mortgage servicing rights, the Company obtains third party valuations based on loan level data including note rate, type and term of the underlying loans. As such, the Company classifies mortgage servicing rights as Level 2. Time Deposits The fair value of maturity deposits is based on the discounted value of contractual cash flows using a replacement cost of funds approach. The discount rate is estimated using the cost of funds borrowing rate in the market. As such, the Company classifies deposits as Level 2. Borrowed Funds The fair value of borrowed funds is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently available for borrowings of similar remaining maturities. As such, the Company classifies borrowed funds as Level 2. Derivatives The fair value of interest rate swaps is determined using inputs that are observable in the market place obtained from third parties including yield curves, publicly available volatilities, and floating indexes and, accordingly, are classified as Level 2 inputs. The credit value adjustments associated with derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. As of June 30, 2020 and 2019, and December 31, 2019, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives due to collateral postings. Customer Loan Derivatives The valuation of the Company’s customer loan derivatives is obtained from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of master netting arrangements and any applicable credit enhancements, such as collateral postings. Limitations Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These values do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company's financial instruments, fair value estimates are based on Management's judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on- and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets and liabilities that are not considered financial instruments include the deferred tax asset, premises and equipment, and other real estate owned. In addition, tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of the estimates. Assets and Liabilities Recorded at Fair Value on a Recurring Basis The following tables present the balances of assets and liabilities that were measured at fair value on a recurring basis as of June 30, 2020, December 31, 2019 and June 30, 2019.

Other real estate owned is presented net of an allowance of $0 at June 30, 2020, 2019 and December 31, 2019. Only collateral-dependent impaired loans with a related specific allowance for loan losses or a partial charge off are included in impaired loans for purposes of fair value disclosures. Impaired loans below are presented net of specific allowances of $623,000, $1,916,000 and $1,893,000 at June 30, 2020, December 31, 2019, and June 30, 2019, respectively.

Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company's various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques using observable inputs when available. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Topic 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. This summary excludes financial assets and liabilities for which carrying value approximates fair values and financial instruments that are recorded at fair value on a recurring basis. Financial instruments for which carrying values approximate fair value include cash equivalents, interest-bearing deposits in other banks, demand, NOW, savings and money market deposits. The estimated fair value of demand, NOW, savings and money market deposits is the amount payable on demand at the reporting date. Carrying value is used because the accounts have no stated maturity and the customer has the ability to withdraw funds immediately. The carrying amount and estimated fair values for financial instruments as of June 30, 2020 were as follows: Carrying value Estimated fair value Level 1 Level 2 Level 3 Financial assets Securities to be held to maturity $ 341,962,000 $ 352,225,000 $ — $ 352,225,000 $ — Loans (net of allowance for loan losses) Commercial Real estate 392,296,000 389,956,000 — 12,000 389,944,000 Construction 46,605,000 46,327,000 — — 46,327,000 Other 323,994,000 321,575,000 — 8,000 321,567,000 Municipal 49,526,000 48,791,000 — — 48,791,000 Residential Term 497,258,000 503,574,000 — 163,000 503,411,000 Construction 14,638,000 14,709,000 — — 14,709,000 Home equity line of credit 85,636,000 85,635,000 — 570,000 85,065,000 Consumer 27,560,000 25,512,000 — — 25,512,000 Total loans 1,437,513,000 1,436,079,000 — 753,000 1,435,326,000 Mortgage servicing rights 1,874,000 1,777,000 — 1,777,000 — Financial liabilities Local certificates of deposit $ 269,054,000 $ 272,305,000 $ — $ 272,305,000 $ — National certificates of deposit 387,579,000 429,110,000 — 429,110,000 — Total certificates of deposits 656,633,000 701,415,000 — 701,415,000 — Repurchase agreements 61,103,000 61,399,000 — 61,399,000 — Federal Home Loan Bank and Federal Reserve Bank borrowings 217,702,000 218,644,000 — 218,644,000 — Total borrowed funds 278,805,000 280,043,000 — 280,043,000 — The carrying amounts and estimated fair values for financial instruments as of December 31, 2019 were as follows: Carrying value Estimated fair value Level 1 Level 2 Level 3 Financial assets Securities to be held to maturity $ 281,606,000 $ 287,045,000 $ — $ 287,045,000 $ — Loans (net of allowance for loan losses) Commercial Real estate 368,645,000 364,626,000 — 2,000 364,624,000 Construction 37,678,000 37,366,000 — — 37,366,000 Other 215,068,000 212,548,000 — 5,046,000 207,502,000 Municipal 41,258,000 40,552,000 — — 40,552,000 Residential Term 491,315,000 491,359,000 — 577,000 490,782,000 Construction 14,785,000 14,786,000 — — 14,786,000 Home equity line of credit 91,149,000 90,959,000 — 954,000 90,005,000 Consumer 25,538,000 23,489,000 — — 23,489,000 Total loans 1,285,436,000 1,275,685,000 — 6,579,000 1,269,106,000 Mortgage servicing rights 1,546,000 2,089,000 — 2,089,000 — Financial liabilities Local certificates of deposit $ 285,602,000 $ 281,480,000 $ — $ 281,480,000 $ — National certificates of deposit 404,377,000 412,337,000 — 412,337,000 — Total deposits 689,979,000 693,817,000 — 693,817,000 — Repurchase agreements 37,450,000 37,450,000 — 37,450,000 — Federal Home Loan Bank advances 147,505,000 140,063,000 — 140,063,000 — Total borrowed funds 184,955,000 177,513,000 — 177,513,000 — The carrying amount and estimated fair values for financial instruments as of June 30, 2019 were as follows: Carrying value Estimated fair value Level 1 Level 2 Level 3 Financial assets Securities to be held to maturity $ 302,527,000 $ 308,075,000 $ — $ 308,075,000 $ — Loans (net of allowance for loan losses) Commercial Real estate 355,285,000 350,390,000 — 622,000 349,768,000 Construction 32,417,000 31,970,000 — — 31,970,000 Other 202,004,000 200,804,000 — 5,315,000 195,489,000 Municipal 36,083,000 35,825,000 — — 35,825,000 Residential Term 480,032,000 475,560,000 — 745,000 474,815,000 Construction 13,212,000 13,089,000 — — 13,089,000 Home equity line of credit 94,009,000 93,260,000 — 11,000 93,249,000 Consumer 24,619,000 22,917,000 — — 22,917,000 Total loans 1,237,661,000 1,223,815,000 — 6,693,000 1,217,122,000 Mortgage servicing rights 1,368,000 2,087,000 — 2,087,000 — Financial liabilities Local certificates of deposit $ 281,903,000 $ 283,746,000 $ — $ 283,746,000 $ — National certificates of deposit 435,095,000 436,682,000 — 436,682,000 — Total certificates of deposits 716,998,000 720,428,000 — 720,428,000 — Repurchase agreements 40,954,000 40,912,000 — 40,912,000 — Federal Home Loan Bank advances 140,904,000 139,880,000 — 139,880,000 — Total borrowed funds 181,858,000 180,792,000 — 180,792,000 —

Accounting Standards Update and Change in Accounting Principle [Abstract]
Impact of Recently Issued Accounting Standards	Impact of Recently Issued Accounting Standards In June 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. Under the new guidance, which will replace the existing incurred loss model for recognizing credit losses, banks and other lending institutions will be required to recognize the full amount of expected credit losses. The new guidance, which is referred to as the current expected credit loss model, requires that expected credit losses for financial assets held at the reporting date that are accounted for at amortized cost be measured and recognized based on historical experience and current and reasonably supportable forecasted conditions to reflect the full amount of expected credit losses. A modified version of these requirements also applies to debt securities classified as available for sale. The ASU was to be effective for all SEC registrants for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. On October 16, 2019 FASB voted to finalize a proposal issued in August 2019 under which the effective implementation date was changed for SEC registrants meeting the definition of a Smaller Reporting Company to fiscal years beginning after December 15, 2022. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within such years. The Company qualifies as a Smaller Reporting Company. It continues to evaluate the impact of the adoption of the ASU on its consolidated financial statements, and continues to anticipate that it may have a material impact upon adoption. The Bank has formed an implementation committee for ASU No. 2016-13. To date, committee members have participated in educational seminars on the new standards, identified the historical data sets that will be necessary to implement the new standard, and have chosen a third-party vendor who provides software solutions for ASU No. 2016-13 modeling and calculation. The Bank is in the late stages of implementing this software and plans to run incurred loss and current expected credit models in parallel until adoption of ASU No. 2016-13. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU was issued to reduce the cost and complexity of the goodwill impairment test. To simplify the subsequent measurement of goodwill, step two of the goodwill impairment test was eliminated. Instead, a Company will recognize an impairment of goodwill should the carrying value of a reporting unit exceed its fair value (i.e. step one). The ASU was effective for the Company on January 1, 2020 and will be applied prospectively. Implementation of this ASU did not have a material effect on the Company's consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU No. 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. Entities are also allowed to elect early adoption for the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. As ASU No. 2018-13 only revises disclosure requirements, it did not have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans . This ASU makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. ASU 2018-14 is effective for fiscal years ending after December 15, 2020; early adoption is permitted. As ASU 2018-14 only revises disclosure requirements, it will not have a material impact on the Company’s consolidated financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of PresentationThe First Bancorp, Inc. ("the Company") is a financial holding company that owns all of the common stock of First National Bank ("the Bank"). The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of Management, all adjustments (consisting of normally recurring accruals) considered necessary for a fair presentation have been included. All significant intercompany transactions and balances are eliminated in consolidation. The income reported for the 2020 period is not necessarily indicative of the results that may be expected for the year ending December 31, 2020. For further information, refer to the consolidated financial statements and notes included in the Company's annual report on Form 10-K for the year ended December 31, 2019.
Financial Derivative Instruments	The Bank uses derivative financial instruments for risk management purposes and not for trading or speculative purposes. As part of its overall asset and liability management strategy, the Bank periodically uses derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. The Bank’s interest rate risk management strategy involves modifying the re-pricing characteristics of certain assets or liabilities so that changes in interest rates do not have a significant effect on net interest income. The Bank recognizes its derivative instruments in the consolidated balance sheet at fair value. On the date the derivative instrument is entered into, the Bank designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Bank formally documents relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedge transactions. The Bank also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items. Changes in fair value of derivative instruments that are highly effective and qualify as cash flow hedges are recorded in other comprehensive income or loss. Any ineffective portion is recorded in earnings. The Bank discontinues hedge accounting when it is determined that the derivative is no longer highly effective in offsetting changes of the hedged risk on the hedged item, or management determines that the designation of the derivative as a hedging instrument is no longer appropriate.
Reclassifications	Certain items from the prior year were reclassified in the financial statements to conform with the current year presentation. These do not have a material impact on the consolidated balance sheet or statement of income and comprehensive income presentations.
Fair Value	Certain assets and liabilities are recorded at fair value to provide additional insight into the Company's quality of earnings. Some of these assets and liabilities are measured on a recurring basis while others are measured on a nonrecurring basis, with the determination based upon applicable existing accounting pronouncements. For example, securities available for sale are recorded at fair value on a recurring basis. Other assets, such as, other real estate owned and impaired loans, are recorded at fair value on a nonrecurring basis using the lower of cost or market methodology to determine impairment of individual assets. The Company groups assets and liabilities which are recorded at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement (with level 1 considered highest and level 3 considered lowest). A brief description of each level follows: Level 1 - Valuation is based upon quoted prices for identical instruments in active markets. Level 2 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 - Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates that market participants would use in pricing the asset or liability. Valuation includes use of discounted cash flow models and similar techniques. The fair value methods and assumptions for the Company's financial instruments and other assets measured at fair value are set forth below. Investment Securities The fair values of investment securities are estimated by independent providers using a market approach with observable inputs, including matrix pricing and recent transactions. In obtaining such valuation information from third parties, the Company has evaluated their valuation methodologies used to develop the fair values in order to determine whether the valuations are representative of an exit price in the Company's principal markets. The Company's principal markets for its securities portfolios are the secondary institutional markets, with an exit price that is predominantly reflective of bid level pricing in those markets. Fair values are calculated based on the value of one unit without regard to any premium or discount that may result from concentrations of ownership of a financial instrument, possible tax ramifications, or estimated transaction costs. If these considerations had been incorporated into the fair value estimates, the aggregate fair value could have been changed. Loans Fair values are estimated for portfolios of loans based on exit pricing notion. The fair values of performing loans are calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest risk inherent in the loan. The estimates of maturity are based on the Company's historical experience with repayments for each loan classification, modified, as required, by an estimate of the effect of current economic and lending conditions, and the effects of estimated prepayments. Assumptions regarding credit risk, cash flows, and discount rates are judgmentally determined using available market information and specific borrower information. Management has made estimates of fair value using discount rates that it believes to be reasonable. However, because there is no market for many of these financial instruments, Management has no basis to determine whether the fair value presented above would be indicative of the value negotiated in an actual sale. As such, the Company classifies loans as Level 3, except for certain collateral-dependent impaired loans. Fair values of impaired loans are based on estimated cash flows and are discounted using a rate commensurate with the risk associated with the estimated cash flows, or if collateral dependent, discounted to the appraised value of the collateral as determined by reference to sale prices of similar properties, less costs to sell. As such, the Company classifies collateral dependent impaired loans for which a specific reserve results in a fair value measure as Level 2. All other impaired loans are classified as Level 3. Other Real Estate Owned Real estate acquired through foreclosure is initially recorded at fair value. The fair value of other real estate owned is based on property appraisals and an analysis of similar properties currently available. As such, the Company records other real estate owned as nonrecurring Level 2. Mortgage Servicing Rights Mortgage servicing rights represent the value associated with servicing residential mortgage loans. Servicing assets and servicing liabilities are reported using the amortization method and compared to fair value for impairment. In evaluating the fair values of mortgage servicing rights, the Company obtains third party valuations based on loan level data including note rate, type and term of the underlying loans. As such, the Company classifies mortgage servicing rights as Level 2. Time Deposits The fair value of maturity deposits is based on the discounted value of contractual cash flows using a replacement cost of funds approach. The discount rate is estimated using the cost of funds borrowing rate in the market. As such, the Company classifies deposits as Level 2. Borrowed Funds The fair value of borrowed funds is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently available for borrowings of similar remaining maturities. As such, the Company classifies borrowed funds as Level 2. Derivatives The fair value of interest rate swaps is determined using inputs that are observable in the market place obtained from third parties including yield curves, publicly available volatilities, and floating indexes and, accordingly, are classified as Level 2 inputs. The credit value adjustments associated with derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. As of June 30, 2020 and 2019, and December 31, 2019, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives due to collateral postings. Customer Loan Derivatives The valuation of the Company’s customer loan derivatives is obtained from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of master netting arrangements and any applicable credit enhancements, such as collateral postings. Limitations
Fair Value of Financial Instruments	Fair Value of Financial Instruments FASB ASC Topic 825 "Financial Instruments" requires disclosures of fair value information about financial instruments, whether or not recognized in the balance sheet, if the fair values can be reasonably determined. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company's various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques using observable inputs when available. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Topic 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. This summary excludes financial assets and liabilities for which carrying value approximates fair values and financial instruments that are recorded at fair value on a recurring basis. Financial instruments for which carrying values approximate fair value include cash equivalents, interest-bearing deposits in other banks, demand, NOW, savings and money market deposits. The estimated fair value of demand, NOW, savings and money market deposits is the amount payable on demand at the reporting date. Carrying value is used because the accounts have no stated maturity and the customer has the ability to withdraw funds immediately.
Impact of Recently Issued Accounting Standards	Impact of Recently Issued Accounting Standards In June 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. Under the new guidance, which will replace the existing incurred loss model for recognizing credit losses, banks and other lending institutions will be required to recognize the full amount of expected credit losses. The new guidance, which is referred to as the current expected credit loss model, requires that expected credit losses for financial assets held at the reporting date that are accounted for at amortized cost be measured and recognized based on historical experience and current and reasonably supportable forecasted conditions to reflect the full amount of expected credit losses. A modified version of these requirements also applies to debt securities classified as available for sale. The ASU was to be effective for all SEC registrants for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. On October 16, 2019 FASB voted to finalize a proposal issued in August 2019 under which the effective implementation date was changed for SEC registrants meeting the definition of a Smaller Reporting Company to fiscal years beginning after December 15, 2022. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within such years. The Company qualifies as a Smaller Reporting Company. It continues to evaluate the impact of the adoption of the ASU on its consolidated financial statements, and continues to anticipate that it may have a material impact upon adoption. The Bank has formed an implementation committee for ASU No. 2016-13. To date, committee members have participated in educational seminars on the new standards, identified the historical data sets that will be necessary to implement the new standard, and have chosen a third-party vendor who provides software solutions for ASU No. 2016-13 modeling and calculation. The Bank is in the late stages of implementing this software and plans to run incurred loss and current expected credit models in parallel until adoption of ASU No. 2016-13. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU was issued to reduce the cost and complexity of the goodwill impairment test. To simplify the subsequent measurement of goodwill, step two of the goodwill impairment test was eliminated. Instead, a Company will recognize an impairment of goodwill should the carrying value of a reporting unit exceed its fair value (i.e. step one). The ASU was effective for the Company on January 1, 2020 and will be applied prospectively. Implementation of this ASU did not have a material effect on the Company's consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU No. 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. Entities are also allowed to elect early adoption for the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. As ASU No. 2018-13 only revises disclosure requirements, it did not have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans . This ASU makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. ASU 2018-14 is effective for fiscal years ending after December 15, 2020; early adoption is permitted. As ASU 2018-14 only revises disclosure requirements, it will not have a material impact on the Company’s consolidated financial statements.
