Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	Note 1. Nature of Operations and Summary of Significant Accounting Policies Patriot National Bancorp, Inc. (the "Company"), a Connecticut corporation, is a bank holding company that was organized in 1999. Patriot Bank, N.A. (the "Bank") (collectively, “Patriot”) is a wholly owned subsidiary of the Company. The Bank is a nationally chartered commercial bank whose deposits are insured under the Bank Insurance Fund, which is administered by the Federal Deposit Insurance Corporation. The Bank provides a full range of banking services to commercial and consumer customers through its main office in Stamford, Connecticut, seven two On March 11, 2003, March 26, 2003, first In accordance with accounting principles generally accepted in the United States of America (“US GAAP”), the Trust is not The preparation of consolidated financial statements in accordance with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and to disclose contingent assets and liabilities. Actual results could differ from those estimates. Management has identified accounting for the allowance for loan losses, the analysis and valuation of its investment securities, and the valuation of deferred tax assets as certain of Patriot’s more significant accounting policies and estimates, in that they are critical to the presentation of Patriot’s financial condition and results of operations. As they concern matters that are inherently uncertain, these estimates require management to make subjective and complex judgments in the preparation of Patriot’s Consolidated Financial Statements. These and other of Patriot’s significant accounting policies are summarized below. Summary of Significant Accounting Policies Principles of consolidation and basis of f inancial statement presentation The Consolidated F inancial Statements include the accounts of Patriot, and the Bank's wholly owned subsidiaries, PinPat Acquisition Corporation and ABC HOLD Co, LLC, (inactive) and have been prepared in conformity with US GAAP. All significant intercompany balances and transactions have been eliminated. Cash and cash equivalents Patriot considers all short-term, highly liquid investments purchased with an original maturity of three three Patriot maintains amounts due from banks which, at times, may not Federal Reserve Bank and Federal Home Loan Bank stock The Bank is required to maintain an investment in capital stock of the Federal Home Loan Bank of Boston (“FHLB”), as collateral, in an amount equal to a percentage of its outstanding mortgage loans and loans secured by residential properties, including mortgage-backed securities. Additionally, the Bank is required to maintain an investment in the capital stock of the Federal Reserve Bank (“FRB”), as collateral, in an amount equal to one six one Shares in the FHLB and FRB are purchased and redeemed based upon their $100 Included in the Bank ’s investment portfolio are shares in the FHLB and FRB of $8.4 $7.7 December 31, 2017 2016, December 31, 2017 2016 no I nvestment Securities Management determines the appropriate classification of securities at the date individual investment securities are acquired, and the appropriateness of such classification is reassessed at each balance sheet date. Debt securities, if any, that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and are recorded at amortized cost. “Trading” securities, if any, are carried at fair value with unrealized gains and losses recognized in earnings. Securities classified as “available-for-sale” are recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss), net of taxes. Purchase premiums and discounts are recognized in interest income using the interest method of accounting, in order to achieve a constant effective yield over the contractual term of the securities. Patriot conducts a quarterly review and evaluation of the securities portfolio to determine if a decline in the fair value of any security below its cost basis is an other-than-temporary impairment (“OTTI”). Our evaluation of OTTI considers the duration and severity of the impairment, our intent to hold the securities, whether or not Security transactions are recorded on the trade date. Realized gains and losses on the sale of securities are determined using the specific identification method, recorded on the trade date, and reported in non-interest income for the period. At December 31, 2017 2016, $4.5 December 31, 2017 2016, Loans receivable Loans that Patriot has the intent and ability to hold until maturity or for the foreseeable future generally are reported at their outstanding unpaid principal balances adjusted for unearned income, an allowance for loan losses, if any, and any unamortized discount, premium and deferred fees. Interest income is accrued based on unpaid principal balance s. Loan application fees are reported as non-interest income, while other certain direct origination costs, or for purchased loans, any discounts or premiums are deferred and amortized to interest income as a level yield adjustment over the respective term of the loan. Loans are placed on non -accrual status or charged off when collection of principal or interest is considered doubtful. The accrual of interest on loans is discontinued no 90 no 180 Accrued uncollected interest income on loans that are placed on non-accrual status or have been charged off is reversed against interest income. Interest income on such non-performing loans is accounted for on the cash-basis of accounting until qualifying for return to accrual status. Any cash received on non-accrual or charged off loans is first Patriot ’s real estate loans are collateralized by real estate located principally in Fairfield and New Haven Counties in Connecticut and Westchester County, New York. Accordingly, the ultimate collectability of a substantial portion of Patriot’s loan portfolio is susceptible to regional real estate market conditions. A loan is considered impaired when, based on current information and events, it is probable that Patriot will be unable to collect the scheduled payments of principal or interest when due, according to the loan’s contractual terms. Factors considered by management in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and shortfalls generally are not Impaired loans also include loans modified in troubled debt restructurings ( “TDR”), where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. TDRs are generally placed on non-accrual status until the loan qualifies for return to accrual status. Loans qualify for return to accrual status once they have demonstrated compliance with the restructured terms of the loan agreement and have performed for a minimum of six Lower balance lending arrangements, such as consumer installment loans, are evaluated for impairment by pooling the loans into homogenous groupings. Accordingly, Patriot does not Allowance for loan losses The allowance for loan losses (“ALL”) is regularly evaluated by management, based upon the nature and volume of the loan portfolio, periodic review of loan collectability using historical experience rates, adverse situations potentially affecting individual borrowers’ ability to repay, the estimated value of any underlying collateral, and prevailing economic conditions on overall segments of the loan portfolio. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The non-specific ALL by loan segment is calculated using a systematic methodology, consisting of a quantitative and qualitative analytical component, applied on a quarterly basis to homogeneous loans. The model is comprised of six Management monitors a distinct set of risk characteristics for e ach loan segment. Additionally, management assesses and monitors risk and performance on a disaggregated basis, including an internal risk rating system for loans included in the Commercial loan segment and analyzing the type of collateral, lien position, and loan-to-value (i.e., LTV) ratio for loans included in the Consumer loan segment. Management ’s ALL process first not Another key assumption is the look-back period (“LBP”), which represents the historical data period utilized to calculate loss rates. A three After considering the historic loss calculations, management applies additional qualitative adjustments to the ALL to reflect the inherent risk of loss that exists in the loan portfolio at the balance sheet date. Qualitative adjustments are made based upon changes in economic conditions, loan portfolio and asset quality data, and credit process changes, such as credit policies or underwriting standards. Evaluation of the ALL requires considerable judgment, in order to adequately estimate and provide for the risk of loss inherent in the loan portfolio segments. Qualitative adjustments are aggregated into the nine ● Changes in lending policies and procedures, including underwriting standards, collection, charge-off , and recovery practices not ● Changes in national, regional, and local economic and business conditions and developments that affect the collectability of the loan portfolio, including the condition of various market segments; ● Changes in the nature and volume of the loan portfolio and terms of loans; ● Changes in the experience, ability and depth of lending management and staff; ● Changes in the volume and loss severity of past due loans, the volume of non-accrual loans, and the volume and loss severity of adversely classified or graded loans; ● Changes in the quality of the loan review system; ● Changes in the value of the underlying collateral for collateral-dependent loans; ● The existence and effect of any concentrations of credit and changes in the level of such concentrations; and ● The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in our current loan portfolio. Patriot provides for loan losses by consistently applying the documented ALL methodology. Loan losses and recoveries are credited to the ALL. Additions to the ALL are charged against income, based on various factors which, in management’s judgment, deserve current recognition in estimating probable losses. Loan losses are charged-off in the period the loans, or portions thereof, are deemed uncollectible. Generally, Patriot will record a loan charge-off (including a partial charge-off) to reduce a loan to the estimated fair value of the underlying collateral, less costs to sell, for collateral dependent loans. Subsequent recoveries, if any, are credited to the ALL. Patriot regularly reviews the loan portfolio and makes adjustments for loan losses, in order to maintain the allowance for loan losses in accordance with US GAAP. three ( 1 Allowances are established for impaired loans (generally defined by Patriot as non-accrual loans, troubled debt restructured loans, and loans that were previously classified as troubled debt restructurings but have been upgraded). The amount of impairment provided as an allowance is represented by the deficiency, if any, between the present value of expected future cash flows discounted at the original loan’s effective interest rate or the underlying collateral value, less estimated costs to sell, if the loan is collateral dependent, and the carrying value of the loan. Impaired loans that have no not ( 2 General allowances are established for loan losses on a portfolio basis for loans that do not The portfolio is grouped into homogeneous risk characteristics, primarily loan type and, if collateral dependent, LTV ratio. Management applies an estimated loss rate to each pool of homogeneous loans. The loss rates applied are based on Patriot’s three may may In addition, a risk rating system is utilized to evaluate the general component of the ALL. Under this system, management assigns risk ratings between one six ( 3 An unallocated component is maintained in the ALL to cover uncertainties that could affect management's estimate of probable losses. The unallocated component of the ALL reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies applied to estimating specific and general losses in the loan portfolio. In underwriting a loan secured by real property, a property appraisal is required to be performed by an independent licensed appraiser that has been approved by Patriot’s Board of Directors. Appraisals are subject to review by independent third may While Patriot uses the best information available to evaluate the ALL, future adjustments to the ALL may may Transfers of financial assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when ( 1 2 no 3 not Other real estate owned Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. In addition, when Patriot acquires other real estate owned (“OREO”), it obtains a current appraisal to substantiate the net carrying value of the asset. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in the results of operations. Costs relating to the development and improvement of the property are capitalized, subject to the limit of fair value of the collateral. Gains or losses are included in non-interest expenses upon disposal. Write-downs of foreclosed properties that are required upon transfer to OREO are charged to the ALL. Thereafter, an allowance for OREO losses is established for any further declines in the property’s value. These losses are included in non-interest expenses in the Consolidated Statements of Income. Premises and equipment Premises and equipment are stated at cost, net of accumulated depreciation and amortization. Leasehold improvements are capitalized and amortized over the shorter of the terms of the related leases or the estimated economic lives of the improvements. Depreciation is charged to operations for buildings, furniture, equipment and software using the straight-line method over the estimated useful lives of the related assets which range from three forty Impairment of assets Long-lived as sets, which are held and used, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not Income taxes Patriot recognizes income taxes under the asset and liability method. Under this method, net deferred taxes are recognized for the estimated tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and loss carry forwards. Deferred tax assets (“DTA”s) and liabilities (“DTL”s) are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on DTAs and DTLs of a change in tax rates is recognized in income in the period that includes the enactment date. On December 22, 2017, 21% 35%, December 2017, $2.8 December 31, 2017. In addition, for the year ended December 31, 2017, $2.8 382 In certain circumstances DTAs are subject to reduction by a valuation allowance. A valuation allowance is subject to ongoing adjustment based on changes in circumstances that affect management ’s judgment about the realizability of the deferred tax asset. Adjustments to increase or decrease the valuation allowance are charged or credited to the deferred tax component of the income tax provision or benefit. Patriot evaluates its ability to realize its net deferred tax assets on a quarterly basis. In doing so, management considers all available evidence, both positive and negative, to determine whether it is more likely than not 2017 2016 not 2029. no December 31, 2017 2016.

Diluted earnings per share reflects additional common shares that would have been outstanding if potentially dilutive securities had been converted to common stock, as well as any adjustments to earnings resulting from the assumed conversion, unless such effect is anti-dilutive. Potential common shares that may Common stock shares held in treasury are not Share-based compensation plan Incentive and compensatory share-based compensation granted to employees is accounted for at the grant date fair value of the award and recognized in the results of operations as compensation expense with an off-setting entry to equity on a straight-line basis over the requisite service period, which is the vesting period. Non-employee members of the Board of Directors are treated as employees for any share-based compensation granted in exchange for their service on the Board of Directors. Patriot does not goods or services received shall be measured at the grant date fair value of the award or the goods or services to be received, if determined to be a more reliable measurement of fair value. A liability will be recognized for the award, which will periodically be adjusted to reflect the then current fair value, and compensation expense will be recognized over the requisite period during which the goods or services are received, so that the fair value at the date of settlement is the compensation expense recognized. The Compensation Committee of the Board of Directors establishes terms and conditions applicable to the vesting of restricted stock awards and stock options. Restricted stock grants generally vest in quarterly or annual installments over a three, four five Treasury Stock Common stock purchased and held in treasury is recorded at cost. Comprehensive income Accounting principles generally require that recognized revenues, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of shareholders' equity in the Consolidated Balance Sheets, such items, along with net income, are components of comprehensive income. Segment reporting Patriot ’s only business segment is Community Banking. During the years ended December 31, 2017, 2016 2015, Fair value Patriot uses fair value measurements to record adjustments to the carrying amounts of certain assets and liabilities. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in certain instances, there are no not may not Provided in these notes to the Consolidated Financial Statements is a detailed summary of Patriot’s application of fair value measurements and the effect on the assets and liabilities presented in the Consolidated Financial Statements.

These loans are generally for the financing of accounts receivable, purchases of inventory, purchases of new or used equipment, or for other short- or long-term working capital purposes. These loans are generally secured by business assets, but are also occasionally offered on an unsecured basis. In granting these types of loans, Patriot considers the borrower’s cash flow as the primary source of repayment, supported by the value of collateral, if any, and personal guarantees, as applicable.

Credit quality is monitored by reviewing certain indicators, including loan to value ratios, debt service coverage ratios, and credit scores. Patriot employs a risk rating system as part of the risk assessment of its loan portfolio. At origination, lending officers are required to assign a risk rating to each loan in their portfolio, which is ratified or modified by the Loan Committee to which the loan is submitted for approval. If financial developments occur on a loan in the lending officer ’s portfolio of responsibility, the risk rating is reviewed and adjusted, as applicable. In carrying out its oversight responsibilities, the Loan Committee can adjust a risk rating based on available information. In addition, the risk ratings on all commercial loans over $250,000 Additionally, Patriot retains a third- party objective and independent loan reviewing expert to perform a quarterly analysis of the results of its risk rating process. The quarterly review is based on a randomly selected sample of loans within established parameters (e.g., value, concentration), in order to assess and validate the risk ratings assigned to individual loans. Any changes to the assigned risk ratings, based on the quarterly review, are required to be approved by the Loan Committee. When assigning a risk rating to a loan, management utilizes the Bank ’s internal eleven not one ● Sub -standard: An asset is classified “sub-standard” if it is not not ● Doubtful: Assets classified as “doubtful” have all of the weaknesses inherent in those classified as “sub-standard”, with the added characteristic that the identified weaknesses make collection or liquidation-in-full improbable, on the basis of currently existing facts, conditions, and values. Charge -offs, to reduce the loan to its recoverable value, generally commence after the loan is classified as “doubtful”.

Financial Instruments with Off-Balance-Sheet Risk In the normal course of business, the Bank is a party to financial instruments with off-balance-sheet risk to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the balance sheet. The contractual amounts of these instruments reflect the extent of involvement Patriot has in particular classes of financial instruments. The contractual amounts of commitments to extend credit and standby letters of credit represent the maximum amount of potential accounting loss should: the contract be fully drawn upon; the customer default; and the value of any existing collateral becomes worthless. Patriot applies its credit policies to entering commitments and conditional obligations and, as with its lending activities, evaluates each customer's creditworthiness on a case-by-case basis. Management believes that it effectively mitigates the credit risk of these financial instruments through its credit approval processes, establishing credit limits, monitoring the on-going creditworthiness of recipients and grantees, and the receipt of collateral as deemed necessary.

Fair Value Disclosures [Text Block]	Note 17. Fair Value and Interest Rate Risk Patriot measures the carrying value of certain financial assets and liabilities at fair value, as required by its policies as a financial institution and by US GAAP. The carrying values of certain assets and liabilities are measured at fair value on a recurring basis, such as available-for-sale securities; while other assets and liabilities are measured at fair value on a non-recurring basis due to external factors requiring management’s judgment to estimate potential losses of value resulting in asset impairments or the establishment of valuation reserves. Measuring assets and liabilities at fair value may Following is a detailed summary of the guidance provided by US GAAP regarding the application of fair value measurements and Patriot ’s application thereof. Additionally, the following information includes detailed summaries of the effects fair value measurements have on the carrying amounts of asset and liabilities presented in the Consolidated Financial Statements. T he objective of fair value measurement is to value an asset that may may US GAAP establishes a framework for measuring assets and liabilities at fair value, as well as certain financial instruments classified in equity. The framework provides a fair value hierarchy, which prioritizes quoted prices in active markets for identical assets and liabilities and minimizes unobservable inputs, which are inputs for which market data are not The three of the fair value hierarchy consist of: Fair Value Hierarchy Level 1 Unadjusted quoted market prices for identical assets or liabilities in active markets that the entity has the ability to access at the measurement date (such as active exchange-traded equity securities and certain U.S. and government agency debt securities). Level 2 Observable inputs other than quoted prices included in Level 1, – Quoted prices for similar assets or liabilities in active markets (such as U.S. agency and government sponsored mortgage-backed securities) – Quoted prices for identical or similar assets or liabilities in less active markets (such as certain U.S. and government agency debt securities, and corporate and municipal debt securities that trade infrequently) – Other inputs that are observable for substantially the full term of the asset or liability (i.e. interest rates, yield curves, prepayment speeds, default rates, etc.).

Investment, Policy [Policy Text Block]	I nvestment Securities Management determines the appropriate classification of securities at the date individual investment securities are acquired, and the appropriateness of such classification is reassessed at each balance sheet date. Debt securities, if any, that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and are recorded at amortized cost. “Trading” securities, if any, are carried at fair value with unrealized gains and losses recognized in earnings. Securities classified as “available-for-sale” are recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss), net of taxes. Purchase premiums and discounts are recognized in interest income using the interest method of accounting, in order to achieve a constant effective yield over the contractual term of the securities. Patriot conducts a quarterly review and evaluation of the securities portfolio to determine if a decline in the fair value of any security below its cost basis is an other-than-temporary impairment (“OTTI”). Our evaluation of OTTI considers the duration and severity of the impairment, our intent to hold the securities, whether or not Security transactions are recorded on the trade date. Realized gains and losses on the sale of securities are determined using the specific identification method, recorded on the trade date, and reported in non-interest income for the period.

Interest income is accrued based on unpaid principal balance s. Loan application fees are reported as non-interest income, while other certain direct origination costs, or for purchased loans, any discounts or premiums are deferred and amortized to interest income as a level yield adjustment over the respective term of the loan. Loans are placed on non -accrual status or charged off when collection of principal or interest is considered doubtful. The accrual of interest on loans is discontinued no 90 no 180 Accrued uncollected interest income on loans that are placed on non-accrual status or have been charged off is reversed against interest income. Interest income on such non-performing loans is accounted for on the cash-basis of accounting until qualifying for return to accrual status. Any cash received on non-accrual or charged off loans is first Patriot ’s real estate loans are collateralized by real estate located principally in Fairfield and New Haven Counties in Connecticut and Westchester County, New York. Accordingly, the ultimate collectability of a substantial portion of Patriot’s loan portfolio is susceptible to regional real estate market conditions. A loan is considered impaired when, based on current information and events, it is probable that Patriot will be unable to collect the scheduled payments of principal or interest when due, according to the loan’s contractual terms. Factors considered by management in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and shortfalls generally are not Impaired loans also include loans modified in troubled debt restructurings ( “TDR”), where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. TDRs are generally placed on non-accrual status until the loan qualifies for return to accrual status. Loans qualify for return to accrual status once they have demonstrated compliance with the restructured terms of the loan agreement and have performed for a minimum of six Lower balance lending arrangements, such as consumer installment loans, are evaluated for impairment by pooling the loans into homogenous groupings. Accordingly, Patriot does not
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for loan losses The allowance for loan losses (“ALL”) is regularly evaluated by management, based upon the nature and volume of the loan portfolio, periodic review of loan collectability using historical experience rates, adverse situations potentially affecting individual borrowers’ ability to repay, the estimated value of any underlying collateral, and prevailing economic conditions on overall segments of the loan portfolio. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The non-specific ALL by loan segment is calculated using a systematic methodology, consisting of a quantitative and qualitative analytical component, applied on a quarterly basis to homogeneous loans. The model is comprised of six Management monitors a distinct set of risk characteristics for e ach loan segment. Additionally, management assesses and monitors risk and performance on a disaggregated basis, including an internal risk rating system for loans included in the Commercial loan segment and analyzing the type of collateral, lien position, and loan-to-value (i.e., LTV) ratio for loans included in the Consumer loan segment. Management ’s ALL process first not Another key assumption is the look-back period (“LBP”), which represents the historical data period utilized to calculate loss rates. A three After considering the historic loss calculations, management applies additional qualitative adjustments to the ALL to reflect the inherent risk of loss that exists in the loan portfolio at the balance sheet date. Qualitative adjustments are made based upon changes in economic conditions, loan portfolio and asset quality data, and credit process changes, such as credit policies or underwriting standards. Evaluation of the ALL requires considerable judgment, in order to adequately estimate and provide for the risk of loss inherent in the loan portfolio segments. Qualitative adjustments are aggregated into the nine ● Changes in lending policies and procedures, including underwriting standards, collection, charge-off , and recovery practices not ● Changes in national, regional, and local economic and business conditions and developments that affect the collectability of the loan portfolio, including the condition of various market segments; ● Changes in the nature and volume of the loan portfolio and terms of loans; ● Changes in the experience, ability and depth of lending management and staff; ● Changes in the volume and loss severity of past due loans, the volume of non-accrual loans, and the volume and loss severity of adversely classified or graded loans; ● Changes in the quality of the loan review system; ● Changes in the value of the underlying collateral for collateral-dependent loans; ● The existence and effect of any concentrations of credit and changes in the level of such concentrations; and ● The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in our current loan portfolio. Patriot provides for loan losses by consistently applying the documented ALL methodology. Loan losses and recoveries are credited to the ALL. Additions to the ALL are charged against income, based on various factors which, in management’s judgment, deserve current recognition in estimating probable losses. Loan losses are charged-off in the period the loans, or portions thereof, are deemed uncollectible. Generally, Patriot will record a loan charge-off (including a partial charge-off) to reduce a loan to the estimated fair value of the underlying collateral, less costs to sell, for collateral dependent loans. Subsequent recoveries, if any, are credited to the ALL. Patriot regularly reviews the loan portfolio and makes adjustments for loan losses, in order to maintain the allowance for loan losses in accordance with US GAAP. three ( 1 Allowances are established for impaired loans (generally defined by Patriot as non-accrual loans, troubled debt restructured loans, and loans that were previously classified as troubled debt restructurings but have been upgraded). The amount of impairment provided as an allowance is represented by the deficiency, if any, between the present value of expected future cash flows discounted at the original loan’s effective interest rate or the underlying collateral value, less estimated costs to sell, if the loan is collateral dependent, and the carrying value of the loan. Impaired loans that have no not ( 2 General allowances are established for loan losses on a portfolio basis for loans that do not The portfolio is grouped into homogeneous risk characteristics, primarily loan type and, if collateral dependent, LTV ratio. Management applies an estimated loss rate to each pool of homogeneous loans. The loss rates applied are based on Patriot’s three may may In addition, a risk rating system is utilized to evaluate the general component of the ALL. Under this system, management assigns risk ratings between one six ( 3 An unallocated component is maintained in the ALL to cover uncertainties that could affect management's estimate of probable losses. The unallocated component of the ALL reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies applied to estimating specific and general losses in the loan portfolio. In underwriting a loan secured by real property, a property appraisal is required to be performed by an independent licensed appraiser that has been approved by Patriot’s Board of Directors. Appraisals are subject to review by independent third may While Patriot uses the best information available to evaluate the ALL, future adjustments to the ALL may may

Other Real Estate Owned, Policy [Policy Text Block]	Other real estate owned Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. In addition, when Patriot acquires other real estate owned (“OREO”), it obtains a current appraisal to substantiate the net carrying value of the asset. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in the results of operations. Costs relating to the development and improvement of the property are capitalized, subject to the limit of fair value of the collateral. Gains or losses are included in non-interest expenses upon disposal. Write-downs of foreclosed properties that are required upon transfer to OREO are charged to the ALL. Thereafter, an allowance for OREO losses is established for any further declines in the property’s value. These losses are included in non-interest expenses in the Consolidated Statements of Income.
Property, Plant and Equipment, Policy [Policy Text Block]	Premises and equipment Premises and equipment are stated at cost, net of accumulated depreciation and amortization.

Income Tax, Policy [Policy Text Block]	Income taxes Patriot recognizes income taxes under the asset and liability method. Under this method, net deferred taxes are recognized for the estimated tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and loss carry forwards. Deferred tax assets (“DTA”s) and liabilities (“DTL”s) are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on DTAs and DTLs of a change in tax rates is recognized in income in the period that includes the enactment date. On December 22, 2017, 21% 35%, December 2017, $2.8 December 31, 2017. In addition, for the year ended December 31, 2017, $2.8 382 In certain circumstances DTAs are subject to reduction by a valuation allowance. A valuation allowance is subject to ongoing adjustment based on changes in circumstances that affect management ’s judgment about the realizability of the deferred tax asset. Adjustments to increase or decrease the valuation allowance are charged or credited to the deferred tax component of the income tax provision or benefit.

Earnings Per Share, Policy [Policy Text Block]	Earnings per Share Basic earnings per share represents earnings accruing to common shareholders and are computed by dividing net income by the weighted average number of common shares outstanding. Diluted earnings per share reflects additional common shares that would have been outstanding if potentially dilutive securities had been converted to common stock, as well as any adjustments to earnings resulting from the assumed conversion, unless such effect is anti-dilutive.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Share-based compensation plan Incentive and compensatory share-based compensation granted to employees is accounted for at the grant date fair value of the award and recognized in the results of operations as compensation expense with an off-setting entry to equity on a straight-line basis over the requisite service period, which is the vesting period. Non-employee members of the Board of Directors are treated as employees for any share-based compensation granted in exchange for their service on the Board of Directors. Patriot does not goods or services received shall be measured at the grant date fair value of the award or the goods or services to be received, if determined to be a more reliable measurement of fair value. A liability will be recognized for the award, which will periodically be adjusted to reflect the then current fair value, and compensation expense will be recognized over the requisite period during which the goods or services are received, so that the fair value at the date of settlement is the compensation expense recognized. The Compensation Committee of the Board of Directors establishes terms and conditions applicable to the vesting of restricted stock awards and stock options. Restricted stock grants generally vest in quarterly or annual installments over a three, four five
Treasury Stock, Policy [Policy Text Block]	Treasury Stock Common stock purchased and held in treasury is recorded at cost.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive income Accounting principles generally require that recognized revenues, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of shareholders' equity in the Consolidated Balance Sheets, such items, along with net income, are components of comprehensive income.

Fair Value Measurement, Policy [Policy Text Block]	Fair value Patriot uses fair value measurements to record adjustments to the carrying amounts of certain assets and liabilities. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in certain instances, there are no not may not Provided in these notes to the Consolidated Financial Statements is a detailed summary of Patriot’s application of fair value measurements and the effect on the assets and liabilities presented in the Consolidated Financial Statements.
