Accounting Policies [Abstract] |
Acquired Loans, Policy [Policy Text Block] | Acquired Loans Acquired loans are initially recorded at their acquisition date fair values. The carryover of allowance for loan losses is prohibited as any credit losses in the acquired loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for acquired loans are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate.
Deteriorated Loans Transferred in, Policy [Policy Text Block] | Acquired Impaired Loans- Purchase Credit Impaired “PCI” Loans Acquired loans that exhibit evidence of deterioration in credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments are accounted for as PCI loans under Accounting Standards Codification (“ASC”) 310 - 30. The excess of undiscounted cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is accreted into interest income over the remaining life of the loans using the interest method. The difference between contractually required payments at acquisition and the undiscounted cash flows expected to be collected at acquisition is referred to as the non-accretable discount. The non-accretable discount represents estimated future credit losses and other contractually required payments that the Company does not expect to collect. Subsequent decreases in expected cash flows are recognized as impairments through a charge to the provision for loan losses resulting in an increase in the allowance for loan losses. Subsequent improvements in expected cash flows result in a recovery of previously recorded allowance for loan losses or a reversal of a corresponding amount of the nonaccretable discount, which the Company then reclassifies as an accretable discount that is accreted into interest income over the remaining life of the loans using the interest method. PCI loans are initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loan. Accordingly, the associated allowance for credit losses related to these loans is not carried over at the acquisition date. Acquired loans that met the criteria for non-accrual of interest prior to acquisition were not considered performing upon acquisition. When the customers resume payments, to make the nonaccrual loans current, the loans may return to accrual status, including the impact of any accretable discounts, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans.
Acquired Non-impaired Loans [Policy Text Block] | Acquired Non-impaired Loans Acquired loans that do not meet the requirements under ASC 310 - 30 are considered acquired non-impaired loans. The difference between the acquisition date fair value and the outstanding balance represents the fair value adjustment for a loan and includes both credit and interest rate considerations. Fair value adjustments may be discounts (or premiums) to a loan’s cost basis and are accreted (or amortized) to net interest income (or expense) over the loan’s remaining life in accordance with ASC 310 - 20. Fair value adjustments for revolving loans are accreted (or amortized) using a straight line method. Term loans are accreted (or amortized) using the constant effective yield method. Subsequent to the purchase date, the methods used to estimate the allowance for loan losses for the acquired non-impaired loans are consistent with the policy for allowance for loan losses described in Note 5.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block] | Allowance for loan losses (“ALLL”) methodology As of September 30, 2018, the Company changed its methodology to estimate its allowance for loan losses. The Bank further segmented its loan pools by Pass, Special Mention, Substandard, and Doubtful risk ratings and assigning additional risk premiums to each group. The qualitative and economic factors for all of the pools and subsegments were also evaluated, with Pass loans receiving adjustments to reflect their credit profile relative to the non-impaired criticized assets. These adjustments generally flow through the qualitative factors addressing severity of past due loans and other similar conditions and the nature and volume of the portfolio and terms of the loans. The Bank’s leveraged lending portfolio was evaluated relative to the rest of the Commercial & Industrial (“C&I”) pool (federal call code 4a ), and an additional risk premium was assigned to those loans in aggregate, and is reflected in the “other reserves” category in the ALLL calculation. These loans were isolated due their risk parameters and profile, including higher leverage than the rest of the Bank’s C&I portfolio. The change in methodology resulted in better alignment of the credit characteristics of the various risk grades and loan types with the calculated allowance. The provision of $50,000 in the third quarter incorporated these changes.
Goodwill and Intangible Assets, Policy [Policy Text Block] | Intangible Assets Intangible assets include core deposit intangibles and goodwill arising from acquisitions. The initial and ongoing carrying value of intangible assets is based upon modeling techniques that require management to make estimates regarding the amount and timing of expected future cash flows. It also requires use of a discount rate that reflects the current return requirements of the market in relation to present risk-free interest rates, required equity market premiums, peer volatility indicators, and company-specific risk indicators. Core deposit intangibles are amortized on straight-line basis over a 10 -year period because that is managements’ conservative estimate of the period Patriot will benefit from Prime Bank’s stable deposit base comprised of funds associated with long term customer relationships. The Company will evaluate goodwill for impairment on an annual basis, or more often if events or circumstances indicate there may be impairment. The annual impairment test will be conducted as of November annually. The implied fair value of a reporting unit’s goodwill is compared to its carrying amount and the impairment loss is measured by the excess of the carrying value over fair value. The fair value of each reporting unit is compared to the carrying amount of such reporting unit in order to determine if impairment is indicated.
Commitments and Contingencies, Policy [Policy Text Block] | Contingent Consideration Contingent consideration represents an estimate of the additional amount of purchase price consideration and is measured based on the probability that certain loans are restructured in accordance with the related acquisition agreement. Resolution of the contingent consideration will result in a cash payment and will be reflected in the financial statements as a measurement period adjustment as they are finalized. Changes will be recognized as an increase or decrease to goodwill, the valuation of the related loans and the contingent consideration/purchase price.
New Accounting Pronouncements, Policy [Policy Text Block] | New Accounting Standards Accounting Standards Adopted During 2018 Effective January 1, 2018, the following new Accounting Standards Updates (ASUs) were adopted by the Company: ASU 2014 - 09 ASU No. 2014 - 09, Revenue from Contracts with Customers (Topic 606 ) including subsequent ASUs issued to clarify this Topic. The ASU, and subsequent related updates, establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most previous revenue recognition guidance, including industry-specific guidance. The ASUs are intended to increase comparability across industries. The core principle of the revenue model is that a company will recognize revenue when it transfers control of goods or services to customers, at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The Company adopted the ASU on January 1, 2018 on a modified retrospective transition approach. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements, and there was no cumulative effect adjustment to opening retained earnings as no material changes were identified in the timing of revenue recognition. ASU 2016 - 01 and ASU 2018 - 03 ASU No. 2016 - 01, Financial Instruments - Overall (Subtopic 825 - 10 ) - Recognition and Measurement of Financial Assets and Financial Liabilities, and ASU No. 2018 - 03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825 - 10 ). The ASUs included targeted amendments in connection with the recognition, measurement, presentation, and disclosure of financial instruments. The main provisions require investments in equity securities to be measured at fair value through net income, unless they qualify for a practical expedient, and require fair value changes arising from changes in instrument-specific credit risk for financial liabilities that are measured under the fair value option to be recognized in other comprehensive income. The provisions also emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes. The Company adopted the ASUs on January 1, 2018 on a modified retrospective basis. In connection with the adoption of ASU 2016 - 01 on January 1, 2018, we refined our methodology to estimate the fair value of our loan portfolio using an exit price notion resulting in prior-periods no longer being comparable. ASU 2016 - 15 In August 2016, the FASB issued ASU 2016 - 15, Statement of Cash Flows : Classification of Certain Cash Receipts and Cash Payments . ASU 2016 - 15 addresses the classification of certain specific transactions presented on the Statement of Cash Flows, in order to improve consistency across entities. Debt prepayment or extinguishment, debt-instrument settlement, contingent consideration payments post-business combination, and beneficial interests in securitization transactions are specific items addressed by this ASU that may affect the Bank. Additionally, the ASU codifies the predominance principle for classifying separately identifiable cash flows. ASU 2016 - 15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. As of September 30, 2018, Patriot did not have any debt prepayment or extinguishment, debt-instrument settlement, or beneficial interests in securitization transactions. Contingent consideration payments post-business combination were classified as a specific item under cash flows from financing activities. ASU 2016 - 18 In November 2016, the FASB issued ASU 2016 - 18, Statement of Cash Flows: Restricted Cash. The purpose of the standard is to improve consistency and comparability among companies with respect to the reporting of changes in restricted cash and cash equivalents on the Statement of Cash Flows. The ASU requires the Statement of Cash Flows to include all changes in total cash and cash equivalents, including restricted amounts, and to the extent restricted cash and cash equivalents are presented in separate line items on the Balance Sheet, disclosure reconciling the change in total cash and cash equivalents to the amounts shown on the Balance Sheet are required. ASU 2016 - 18 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. As of September 30, 2018 and December 31, 2017, Patriot did not have restricted cash and cash equivalents separately disclosed on its Balance Sheet. In the future, if Patriot’s activities warrant presenting separate line items on its Balance Sheet for restricted cash and cash equivalents, management does not envision any difficulties implementing the requirements of ASU 2016 - 18, as applicable. ASU 2017 - 09 In May 2017, the FASB issued ASU 2017 - 09, Scope of Modification Accounting , which provide guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718 Stock compensation. The ASU is effective to all entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. This ASU did not have a material impact on its Consolidated Financial Statements. ASU 2018 - 04 ASU 2018 - 04 - Investments - Debt Securities (Topic 320 ) and Regulated Operations (Topic 980 ): The amendment in this ASU adds, amends and supersedes various paragraphs that contain SEC guidance in ASC 320, Investments-Debt Securities and ASC 980, Regulated Operations. The amendments in this ASU are effective when a registrant adopts ASU 2016 - 01, which for Patriot, was January 1, 2018. This amendment did not have an impact on the Company’s Consolidated Financial Statements. Accounting Standards Issued But Not Yet Adopted ASU 2016 - 02 In February 2016, the FASB issued ASU No. 2016 - 02, Leases. This ASU was issued to improve the financial reporting of leasing activities and provide a faithful representation of leasing transactions and improve understanding and comparability of a lessee's financial statements. Under the new accounting guidance, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. This ASU will require both finance and operating leases to be recognized on the balance sheet. This ASU will affect all companies and organizations that lease real estate. The FASB issued an update in January 2018 ( ASU 2018 - 01 ) providing an optional transition practical expedient to not evaluate under Topic 842 land easements that exist or expired before the entity's adoption of Topic 842. This ASU will become effective for interim and annual reporting periods beginning after December 15, 2018. The Company will adopt this new accounting guidance as required. Management is currently evaluating the impact of the new standard on its Consolidated Financial Statements. ASU 2016 - 13 In June 2016, the FASB issued ASU 2016 - 13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. The ASU changes the methodology for measuring credit losses on financial instruments measured at amortized cost to a current expected loss (“CECL”) model. Under the CECL model, entities will estimate credit losses over the entire contractual term of a financial instrument from the date of initial recognition of the instrument. The ASU also changes the existing impairment model for available-for-sale debt securities. In cases where there is neither the intent nor a more-likely-than- not requirement to sell the debt security, an entity will record credit losses as an allowance rather than a direct write-down of the amortized cost basis. Additionally, ASU 2016 - 13 notes that credit losses related to available-for-sale debt securities and purchased credit impaired loans should be recorded through an allowance for credit losses. ASU 2016 - 13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2018. Management is currently evaluating the impact that the standard will have on its Consolidated Financial Statements. ASU 2017 - 04 In January 2017, the FASB issued ASU 2017 - 04, Intangibles-Goodwill and Other (Topic 350 ): Simplifying the Test for Goodwill Impairment: The objective of this guidance is to simplify an entity’s required test for impairment of goodwill by eliminating Step 2 from the goodwill impairment test. In Step 2 an entity measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. In computing the implied fair value of goodwill, an entity had to determine the fair value at the impairment date of its assets and liabilities, including any unrecognized assets and liabilities, following a procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under this Update, an entity should perform its annual or quarterly goodwill impairment test by comparing the fair value of the reporting unit with its carrying amount and record an impairment charge for the excess of the carrying amount over the reporting unit’s fair value. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit and the entity must consider the income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. This guidance is effective for a public business entity that is an SEC filer for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of this standard is not expected to have a material impact on the Company’s Consolidated Financial Statements. ASU 2017 - 08 In March 2017, the FASB issued ASU 2017 - 08, Premium Amortization on Purchased Callable Debt Securities , which amends the amortization period for certain purchased callable debt securities held at a premium, shortening such period to the earliest call date. The ASU is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. For all other entities, the ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Earlier application is permitted for all entities, including adoption in an interim period. If an entity early adopts the ASU in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. Management is currently evaluating the impact the adoption of ASU 2017 - 08 will have on its Consolidated Financial Statements. ASU 2018 - 02 In February 2018, the FASB issued ASU 2018 - 02, Income Statement-Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income , which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Consequently, the amendments eliminated the stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. The amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not effected. The amendments in this ASU also require certain disclosures about stranded tax effects. The guidance in this ASU will become effective for reporting periods beginning after December 15, 2018, with early adoption permitted, and will be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. Management is currently evaluating the impact that the standard will have on its Consolidated Financial Statements. ASU 2018 - 05 ASU 2018 - 05 - Income Taxes (Topic 740 ) : Amendment to clarify situations where a registrant does not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting under ASC 740 for certain income tax effects of the Tax Cuts and Jobs Act for the reporting period. As of December 31, 2017, the Company partially completed the accounting for the tax effects of enactment of the Tax Cuts and Jobs Act, and management made reasonable estimates of the effects of a reduced federal corporate income tax rate on its existing deferred tax balances. The Company will continue to make and refine its calculations during the one -year re-measurement period as additional analysis is completed. In addition, these estimates may be affected as management gains a more thorough understanding of the new tax reform legislation. ASU 2018 - 13 In August 2018, the FASB issued ASU No. 2018 - 13, Fair Value Measurement (Topic 820 ) - Changes to the Disclosure Requirements for Fair Value Measurement , to modify the disclosure requirements on fair value measurements. This ASU removes requirements to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements. ASU 2018 - 13 clarifies that disclosure regarding measurement uncertainty is intended to communicate information about the uncertainty in measurement as of the reporting date. ASU 2018 - 13 adds certain disclosure requirements, including disclosure of changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively, while all other amendments should be applied retrospectively for all periods presented upon their effective date. Management is currently evaluating the impact of adopting the new guidance on the Consolidated Financial Statements, but it is not expected to have a material impact.
