Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements include the accounts of Two River Bancorp (the “Company”), a bank holding company, and its wholly-owned subsidiary, Two River Community Bank (“Two River” or the “Bank”); Two River’s wholly-owned subsidiaries, TRCB Investment Corporation and TRCB Holdings Eight LLC. All inter-company balances and transactions have been eliminated in the consolidated financial statements. 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 pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), including the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for full year financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal, recurring nature. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 . These consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 24, 2017 (the “ 2016 Form 10-K”). For a description of the Company’s significant accounting policies, refer to Note 1 of the Notes to Consolidated Financial Statements in the 2016 Form 10-K. The Company has evaluated events and transactions occurring subsequent to the balance sheet date of September 30, 2017 for items that should potentially be recognized or disclosed in these consolidated financial statements.

New Accounting Standards

New Accounting Standards	9 Months Ended
	Sep. 30, 2017
Accounting Policies [Abstract]
New Accounting Standards	NEW ACCOUNTING STANDARDS ASU 2014-09: In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers. Subsequently, the FASB issued guidance codified in ASC 606, "Revenue from Contracts with Customers," which amends the guidance in former ASC 605 "Revenue Recognition." The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This will be achieved in a five-step process. Enhanced disclosures also will be required. This guidance is effective on a retrospective basis, either to each reporting period presented or with the cumulative effect of initially applying this guidance recognized at the date of initial application for annual reporting periods, including interim reporting periods within those annual reporting periods, beginning after December 15, 2017. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company's revenue is comprised of net interest income and non-interest income. The scope of the guidance excludes net interest income. Accordingly, the majority of our revenues will not be affected. The Company has prepared the initial review of its contracts and other agreements that are within the scope of this guidance and will complete the process pending review of additional guidance. While we are continuing to assess all potential impacts these standards will have on our financial position and results of operations, our initial conclusions indicate that these standards will not materially change the timing of revenue recognition. The Company will adopt the requirements of the new standard on January 1, 2018, utilizing the modified retrospective transition method. Upon adoption, the Company will recognize the cumulative effect of adopting this ASU as an adjustment to the opening balance of retained earnings. Prior periods will not be retrospectively adjusted. The Company continues to evaluate the impact of the guidance on disclosures. ASU 2016-01: In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income; provides for a practicability exception election for equity investments without readily determinable fair values; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; eliminates the requirement for nonpublic business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial assets on the balance sheet or the accompanying notes to the financial statements and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU 2016-01 will have on its statement of financial position or financial statement disclosures. ASU 2016-02: In February 2016, the FASB issued ASU No. 2016-02, Leases. From the lessee’s perspective, the new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement for a lessee. From the lessor’s perspective, the new standard requires a lessor to classify leases as either sales-type, finance or operating. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as a financing. If the lessor doesn’t convey risks and rewards or control, an operating lease results. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. A modified retrospective transition approach is required for lessors for sales-type, direct financing, and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company has determined that the provisions of ASU 2016-02 will result in an increase in assets to recognize the present value of the lease obligations with a corresponding increase in liabilities, however, the Company does not expect this to have a material impact on its financial position, results of operations or cash flows. ASU 2016-13: In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326) . This ASU requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Entities will now use forward-looking information to better form their credit loss estimates. The ASU also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. For public entities that are SEC filers, this ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. For public entities that are not SEC filers, this ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For non-public entities, this ASU is effective for fiscal years beginning after December 15, 2020, and for interim periods within fiscal years beginning after December 15, 2021. Early application will be permitted for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. While the Company is currently evaluating the provisions of ASU 2016-13 to determine the potential impact the new standard will have on its consolidated financial statements, it has taken steps to prepare for the implementation when it becomes effective, such as forming an internal task force, gathering pertinent data, consulting with outside professionals and evaluating its current IT systems. ASU 2016-15: In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . ASU 2016-15 addresses changes to reduce the presentation diversity of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs, settlement of certain debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, and distributions received from equity method investees. The guidance becomes effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. An entity that elects early adoption must adopt all of the amendments in the same period. The new standard will be applied retrospectively, but may be applied prospectively if retrospective application would be impracticable. The Company is currently evaluating the new guidance and has not determined the impact this standard may have on its consolidated statement of cash flows. ASU 2016-18: In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 was issued to address divergence in the way restricted cash is classified and presented. The amendments in the update require that a statement of cash flows explain the change during a reporting period in the total of cash, cash equivalents, and amounts generally described as restricted cash and restricted cash equivalents. The amendments in this update apply to entities that have restricted cash or restricted cash equivalents and are required to present a statement of cash flows under Topic 230. The amendment says that transfers between cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents are not part of the entity's operating, investing, and financing activities. For public business entities, ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact of the adoption of ASU 2016-18 on its consolidated financial statements. ASU 2017-04: In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350) . ASU 2017-04 removes Step 2 from the goodwill impairment test. Under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. For public entities that are SEC filers, this ASU is effective for its annual, or any goodwill impairment tests in fiscal years, beginning after December 15, 2019. For public entities that are not SEC filers, this ASU is effective for its annual, or any goodwill impairment tests in fiscal years, beginning after December 15, 2020. For non-public entities, this ASU is effective for its annual, or any goodwill impairment tests in fiscal years, beginning after December 15, 2021. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the new guidance but has determined that this standard should not have a material impact on its consolidated financial statements. ASU 2017-09: In May 2017, the FASB issued ASU No. 2017-09, “Stock Compensation, Scope of Modification Accounting.” This ASU clarifies when changes to the terms of conditions of a share-based payment award must be accounted for as modifications. Companies will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. The new guidance should reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications, as the guidance will allow companies to make certain non-substantive changes to awards without accounting for them as modifications. It does not change the accounting for modifications. ASU No. 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017; early adoption is permitted. ASU No. 2017-09 is not expected to have a material impact on the Company’s consolidated financial statements.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	GOODWILL The Company’s goodwill was recognized in connection with the acquisition of The Town Bank (“Town Bank”) in April 2006. GAAP requires that goodwill be tested for impairment annually or more frequently if impairment indicators arise utilizing a two-step methodology. However, a qualitative factor test can be performed to determine whether it is necessary to perform the two-step quantitative impairment test. If this qualitative test determines it is not likely (less than 50% probability) the fair value of the reporting unit is less than book value, then the Company does not have to perform a step one quantitative test and goodwill can be considered not impaired. The Company reviewed the requirements of ASU 350-20 and examples of qualitative assessments to determine whether the weight of evidence indicates greater than 50% likelihood exists that the carrying value of the reporting unit exceeds it's fair value. The nine qualitative assessments used are macroeconomic factors, banking industry conditions, banking industry merger and acquisition trends, bank historical performance, parent stock price, expected bank performance, change of control premium (parent), change of control premium (peer), and other factors. The Company performed its annual qualitative factor impairment test as of August 31, 2017. Based on the results of this analysis, the Company determined that there was no impairment on the current goodwill balance of $18,109,000 .

Earnings Per Share [Abstract]
Earnings Per Common Share	EARNINGS PER COMMON SHARE Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding excluding restricted stock awards outstanding during the period. Diluted earnings per common share reflects additional shares of common stock that would have been outstanding if dilutive potential shares of common stock had been issued relating to outstanding stock options and restricted stock awards. Potential shares of common stock issuable upon the exercise of stock options are determined using the treasury stock method. All share and per share data have been adjusted to reflect a 5% stock dividend paid on February 28, 2017. The following table sets forth the computations of basic and diluted earnings per common share: Three Months Ended Nine Months Ended September 30, September 30, (dollars in thousands, except per share data) (dollars in thousands, except per share data) 2017 2016 2017 2016 Net income $ 2,237 $ 2,644 $ 6,167 $ 6,064 Weighted average common shares outstanding – Basic 8,392,924 8,322,542 8,372,913 8,318,736 Effect of dilutive stock options and restricted stock 263,062 214,848 274,241 196,034 Weighted average common shares outstanding – Diluted 8,655,986 8,537,390 8,647,154 8,514,770 Basic earnings per common share $ 0.27 $ 0.32 $ 0.74 $ 0.73 Diluted earnings per common share $ 0.26 $ 0.31 $ 0.71 $ 0.71 Dilutive securities in the table above exclude common stock options with exercise prices that exceed the average market price of the Company’s common stock during the periods presented. Inclusion of these common stock options would be anti-dilutive to the diluted earnings per common share calculation. There were no stock options that were anti-dilutive for the three and nine months ended September 30, 2017 and 2016.

The sale during 2016 was a municipal bond, which was carried in our held to maturity portfolio. The Company sold this bond out of its held to maturity portfolio due to significant deterioration in the issuer’s creditworthiness. Investment securities with a carrying value of $33.1 million at both September 30, 2017 and December 31, 2016 , were pledged as collateral to secure securities sold under agreements to repurchase and public deposits as required or permitted by law.

In management’s opinion, the unrealized losses in corporate debt, U.S. Government agencies, U.S. Government collateralized residential mortgage obligations, GSE residential mortgage-backed securities and the CRA mutual fund reflect changes in interest rates subsequent to the acquisition of specific securities. The unrealized loss for corporate debt securities also reflects a widening of spreads due to the liquidity and credit concerns in the financial markets. The Company may, if conditions warrant, elect to sell debt securities at a loss and redeploy the proceeds into other investments in an effort to improve returns, risk profile and overall portfolio diversification. The Company will recognize any losses when the decision is made. As of September 30, 2017 , the Company did not intend to sell these debt securities prior to market recovery. Included in corporate debt securities are four individual trust preferred securities issued by large financial institutions with Moody’s ratings from Baa1to Ba1. At September 30, 2017 , all of these securities are current with their scheduled interest payments. These single issue securities are all from large money center banks. Management concluded that these securities were not other-than-temporarily impaired as of September 30, 2017 . These four securities have an amortized cost value of $2.8 million and a fair value of $2.7 million at September 30, 2017 . There were no other-than-temporary impairments recognized during the three and nine months ended September 30, 2017 and 2016 .

Loans Receivable And Allowance

Loans Receivable And Allowance For Loan Losses	9 Months Ended

Receivables [Abstract]
Loans Receivable And Allowance For Loan Losses	LOANS RECEIVABLE AND ALLOWANCE FOR LOAN LOSSES Loans receivable, which management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances, net of an allowance for loan losses and any deferred fees or costs. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) of the related loans. The Company is generally amortizing these amounts over the contractual life of the loan. Generally, loans held for sale are designated at time of origination, generally consist of newly originated fixed rate residential mortgage loans and are recorded at the lower of aggregate cost or estimated fair value in the aggregate. During the three months ended September 30, 2017 , the Company did not transfer any loans from held for investment to held for sale, while during the nine months ended September 30, 2017 , the Company transferred $8.2 million from held for investment to held for sale. During the three and nine months ended September 30, 2016 , the Company did not transfer any loans from held for investment to held for sale. Gains are recognized on a settlement-date basis and are determined by the difference between the net sales proceeds and the carrying value of the loans, including any net deferred fees or costs. The loans receivable portfolio is segmented into five categories, those being a) Commercial and industrial, b) Real estate-construction (consisting of both residential and commercial construction), c) Real estate-commercial, d) Real estate-residential, and e) Consumer. For all classes of loans receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest previously accrued on these loans is reversed from income. Interest received on nonaccrual loans, including impaired loans, generally is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time (generally six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments. The allowance for credit losses consists of the allowance for loan losses and the reserve for unfunded lending commitments. The allowance for loan losses represents management’s estimate of losses inherent in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The reserve for unfunded lending commitments represents management’s estimate of losses inherent in its unfunded loan commitments and is recorded in other liabilities on the consolidated balance sheet, which at September 30, 2017 and December 31, 2016 , the Company had no such reserves. The allowance for loan losses is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectable are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a monthly evaluation of the adequacy of the allowance. The allowance is based on the Company’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. For loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of the loan. The specific component relates to loans that are classified as impaired. When a loan is impaired, there are three acceptable methods under ASC 310-10-35 for measuring the impairment: 1. The loan’s observable market price; 2. The fair value of the underlying collateral; or 3. The present value (PV) of expected future cash flows. Loans that are considered “collateral-dependent” should be evaluated under the “Fair market value of collateral.” Loans that are still expected to be supported by repayment from the borrower should be evaluated under the “Present value of future cash flows.” For the most part, the Company measures impairment under the “Fair market value of collateral” for any loan that would rely on the value of collateral for recovery in the event of default. The individual impairment analysis for each loan is clearly documented as to the chosen valuation method. The general component covers pools of loans by loan class including commercial and industrial, real estate-construction and real estate-commercial not considered impaired as well as smaller balance homogeneous loans such as real estate-residential and consumer. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors. These qualitative risk factors include: 1. Changes in lending policy and procedures, including changes in underwriting standards and collection practices not previously considered in estimating credit losses. 2. Changes in relevant economic and business conditions. 3. Changes in nature and volume of the loan portfolio and in the terms of loans. 4. Changes in experience, ability and depth of lending management and staff. 5. Changes in the volume and severity of past due loans, the volume of non-accrual loans and the volume and severity of adversely classified loans. 6. Changes in the quality of the loan review system. 7. Changes in the value of underlying collateral for collateral-dependent loans. 8. The existence and effect of any concentration of credit and changes in the level of such concentrations. 9. The effect of other external forces such as competition, legal and regulatory requirements on the level of estimated credit losses in the existing portfolio. Each factor is assigned a risk value to reflect low, moderate or high risk assessments based on management’s best judgment using current market, macro and other relevant information available at the time of the evaluation. Adjustments to the factors are supported through documentation in each factor and accompany the allowance for loan loss calculation. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. A loan is considered impaired when it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial and industrial, real estate-commercial, real estate-construction, real estate-residential and consumer loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. An allowance for loan losses is established for an impaired loan if its carrying value exceeds its estimated fair value. The estimated fair values of substantially all of the Company’s impaired loans are measured based on the estimated fair value of the loan’s collateral. For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the original appraisal and the condition of the property. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property. For commercial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. The allowance calculation methodology includes further segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors and value of collateral, if appropriate, are evaluated annually for commercial loans or when credit deficiencies arise, such as delinquent loan payments, for commercial and consumer loans. Credit quality risk ratings include regulatory classifications of special mention, substandard, doubtful and loss. Loans classified special mention have potential weaknesses that deserve management’s close attention. If uncorrected, the potential weaknesses may result in deterioration of the repayment prospects. Loans classified substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They include loans that are inadequately protected by the current sound net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified doubtful have all the weaknesses inherent in loans classified substandard with the added characteristics that collection or liquidation in full, on the basis of current conditions and facts, is highly improbable. Loans classified as a loss are considered uncollectable and are charged to the allowance for loan losses. Loans not classified are rated pass. In addition, federal and state regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses and may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to management. Based on management’s comprehensive analysis of the loan portfolio, management believes the current level of the allowance for loan losses is adequate. The components of the loan portfolio held for investment at September 30, 2017 and December 31, 2016 are as follows: September 30, December 31, 2017 2016 (In Thousands) Commercial and industrial $ 99,601 $ 93,697 Real estate – construction 118,553 111,914 Real estate – commercial 507,507 460,685 Real estate – residential 62,416 59,065 Consumer 28,773 28,279 816,850 753,640 Allowance for loan losses (10,223 ) (9,565 ) Unearned fees (772 ) (548 ) Net Loans $ 805,855 $ 743,527 The performance and credit quality of the loan portfolio is monitored by analyzing the age of the loans receivable as determined by the length of time a recorded payment is past due.

There were no new TDR's that occurred during the three months ended September 30, 2016 . The following table presents new TDR's that occurred during the nine months ended September 30, 2017 and 2016: Nine months ended September 30, 2017 Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (Dollars in Thousands) Troubled debt restructuring: Commercial and industrial 2 $ 320 $ 320 Real estate – construction 1 150 150 3 $ 470 $ 470 Nine months ended September 30, 2016 Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (Dollars in Thousands) Troubled debt restructuring: Commercial and industrial 1 $ 257 $ 257 Loans whose terms are modified are classified as TDRs if the Company grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a TDR generally involve a temporary reduction in interest rate or a modification of a loan’s amortization schedule. Non-accrual TDRs are restored to accrual status if principal and interest payments, under the modified terms, are current for six consecutive months after the modification is in place. Loans classified as TDRs, including those restored to accrual status, are designated as impaired. The Company’s TDR modifications are made on terms typically up to 12 months in order to aggressively monitor and track performance of the credit. The short-term modifications are monitored for continued performance for an additional period of time after the expiration of the concession. Balance reductions and annualized loss rates are also important metrics that are monitored. The main objective of the modification program is to reduce the payment burden for the borrower and improve the net present value of the Company’s expected cash flows. Impaired loans are individually assessed to determine that the loan’s carrying value is not in excess of the estimated fair value of the collateral (less cost to sell), if the loan is collateral dependent, or the present value of the expected future cash flows, if the loan is not collateral dependent. Management performs a detailed evaluation of each impaired loan and generally obtains updated appraisals as part of the evaluation. In addition, management adjusts estimated fair value down to appropriately consider recent market conditions, our willingness to accept a lower sales price to effect a quick sale, and costs to dispose of any supporting collateral.

Stock-Based Compensation Plans

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation Plans	STOCK-BASED COMPENSATION PLANS The Two River Bancorp 2007 Equity Incentive Plan (the “Plan”) provides that the Compensation Committee of the Board of Directors (the “Committee”) may grant to those individuals who are eligible under the terms of the Plan stock options, shares of restricted stock, or such other equity incentive awards as the Committee may determine. As of September 30, 2017 , the number of shares of Company common stock remaining and available for future issuance under the Plan is 154,534 after adjusting for subsequent stock dividends. Shares reserved under the Plan will be issued out of authorized and unissued shares, or treasury shares, or partly out of cash, as determined by the Board. From the adoption of the Plan until March 20, 2017, options awarded under the Plan were permitted to be either options that qualify as incentive stock options (“ISOs”) under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), or options that do not, or cease to, qualify as incentive stock options under the Code (“nonqualified stock options” or “NQSOs”). However, after March 20, 2017, only NQSOs may be awarded under the Plan. Awards may be granted under the Plan to directors and employees, and to other persons who provide substantial services to the Company. The exercise price per share purchasable under an option awarded under the Plan may not be less than the fair market value of a share of stock on the date of grant of the option. The Committee determines the vesting period and term of each option, provided that no ISO is permitted to have a term in excess of ten years after the date of grant. Restricted stock is stock which is subject to certain transfer restrictions and to a risk of forfeiture. The Committee will determine the period over which any restricted stock which is issued under the Plan will vest, and will impose such restrictions on transferability, risk of forfeiture and other restrictions as the Committee may in its discretion determine. Unless restricted by the Committee, a participant granted restricted stock will have all of the rights of a shareholder, including the right to vote the restricted stock and the right to receive dividends with respect to that stock. Unless otherwise provided by the Committee in the award document or subject to other applicable restrictions, in the event of a Change in Control (as defined in the Plan) all non-forfeited options and awards carrying a right to exercise that was not previously exercisable and vested will become fully exercisable and vested as of the time of the Change in Control, and all restricted stock and awards subject to risk of forfeiture will become fully vested. Stock Options For the three and nine months ended September 30, 2017 , there were no stock option grants awarded to either directors or officers. Stock-based compensation expense related to the stock option grants was approximately $20,000 and $60,000 during the three and nine month periods ended September 30, 2017 , as compared to $29,000 and 86,000 for the same three and nine month periods in 2016 , respectively, and is included in salaries and employee benefits on the statement of operations. Total unrecognized compensation cost related to non-vested options under the Plan was $126,000 as of September 30, 2017 and will be recognized over the subsequent weighted average life of 2.6 years. The following table presents information regarding the Company’s outstanding stock options, after adjusting for subsequent stock dividends, at September 30, 2017 : Number of Shares Weighted Average Price Weighted Average Remaining Contractual Life (years) Aggregate Intrinsic Value Options outstanding, December 31, 2016 432,451 $ 5.05 Options granted — — Options exercised (65,948 ) 4.03 Options forfeited (2,541 ) 7.81 Options outstanding, September 30, 2017 363,962 $ 5.20 4.06 $ 4,971,641 Options exercisable, September 30, 2017 295,319 $ 4.47 3.30 $ 4,245,250 Option price range at September 30, 2017 $2.87 to $11.21 The total intrinsic value of options exercised during the three and nine months ended September 30, 2017 was $351,000 and $875,000 , respectively. Cash received from such exercises was $105,000 and $266,000 , respectively. The total intrinsic value of options exercised during the three and nine months ended September 30, 2016 was $28,000 and $140,000 , respectively. Cash received from such exercises was $16,000 and $89,000 , respectively. There was a $32,000 and $139,000 income tax benefit recognized in the three and nine months ended September 30, 2017 relating to the adoption of ASU 2016-09, Compensation-Stock Compensation, Improvements to Employee Share-Based Payment Accounting attributable to stock options. There was no tax benefit recognized in the three and nine months ended September 30, 2016 . The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model. Restricted Stock Restricted stock is valued at the market value on the date of grant and expense is evenly attributed to the period in which the restrictions lapse. Compensation expense related to restricted stock was $37,000 and $142,000 for the three and nine month periods ended September 30, 2017 , respectively as compared to $53,000 and $76,000 for the three and nine periods ended September 30, 2016 and is included in salaries and employee benefits on the statement of operations. There was a $0 and $38,000 income tax benefit recognized in the three and nine months ended September 30, 2017 , respectively, relating to the adoption of ASU 2016-09 attributable to restricted stock awards. There was no tax benefit recognized during the three and nine months ended September 30, 2016 . Total unrecognized compensation cost related to restricted stock under the Plan as of September 30, 2017 was $431,000 and will be recognized over the subsequent weighted average life of 3.2 years. The following table summarizes information about restricted stock, after adjusting for subsequent stock dividends, at September 30, 2017 : Number of Shares Weighted Unvested at December 31, 2016 34,082 $ 8.93 Restricted stock earned (13,650 ) 9.56 Granted 21,018 16.06 Unvested at September 30, 2017 41,450 $ 12.33

Guarantees

Guarantees	9 Months Ended

Guarantees [Abstract]
Guarantees	GUARANTEES The Company does not issue any guarantees that would require liability recognition or disclosure, other than its standby letters of credit. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Generally, all letters of credit, when issued, have expiration dates within one year. The credit risks involved in issuing letters of credit are essentially the same as those that are involved in extending loan facilities to customers. The Company generally holds collateral and/or personal guarantees supporting these commitments. As of September 30, 2017 , the Company had $5.3 million of commercial and similar letters of credit. Management believes that the current amount of the liability as of September 30, 2017 for guarantees under standby letters of credit issued is not material.

Offsetting [Abstract]
Securities Sold Under Agreements to Repurchase	SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE The Bank enters into Sweep Account Agreements with certain of its deposit account holders for repo sweep arrangements under which funds in excess of a predetermined amount are removed from each such depositor’s account at the end of each banking day, and the Bank’s obligation to restore those funds to the account at the beginning of the following banking day is evidenced by an integrated retail repurchase agreement (a “Repurchase Agreement”) secured by a collateral interest in favor of the depositor in certain government securities held by a third party custodian. The Bank’s obligation to restore the funds under the Repurchase Agreements is accounted for as a collateralized financing arrangement (i.e., secured borrowings), and not as a sale and subsequent repurchase of securities. The obligation to restore the funds to each account is reflected as a liability in the Company's consolidated balance sheets, while the securities underlying the repurchase agreements remain in the respective securities accounts. There is no offsetting or netting of the securities against the Repurchase Agreement obligation. The following table presents the contractual maturities of the Repurchase Agreements as of September 30, 2017 and December 31, 2016 , disaggregated by the class of collateral pledged: Maturity of Repurchase Agreements (dollars in thousands) Overnight and Continuous Up to 30 days 30 to 90 days Over 90 days Total September 30, 2017 Class of Collateral Pledged: U.S. Government agency securities $ 7,722 $ — $ — $ — $ 7,722 GSE – residential mortgage-backed securities 11,414 — — — 11,414 U.S. Government collateralized residential mortgage obligations 7,322 — — — 7,322 Total $ 26,458 $ — $ — $ — $ 26,458 Gross amount of recognized liabilities for repurchase agreements and securities lending $ 22,576 Excess of collateral pledged over recognized liability $ 3,882 Maturity of Repurchase Agreements (dollars in thousands) Overnight and Continuous Up to 30 days 30 to 90 days Over 90 days Total December 31, 2016 Class of Collateral Pledged: U.S. Government agency securities $ 8,371 $ — $ — $ — $ 8,371 GSE – residential mortgage-backed securities 9,074 — — — 9,074 U.S. Government collateralized residential mortgage obligations 13,895 — — — 13,895 Total $ 31,340 $ — $ — $ — $ 31,340 Gross amount of recognized liabilities for repurchase agreements and securities lending $ 19,915 Excess of collateral pledged over recognized liability $ 11,425 The potential risks associated with the Repurchase Agreements and related pledged collateral, including obligations arising from a decline in the fair value of the pledged collateral, are minimal due to the fact that the Repurchase Agreements pertain to overnight borrowings and therefore not subject to fluctuations in fair market value.

Brokers and Dealers [Abstract]
Subordinated Debentures	SUBORDINATED DEBENTURES In December 2015, the Company completed a private placement of $10 million in aggregate principal amount of fixed to floating rate subordinated debentures to certain institutional accredited investors. The subordinated debentures have a maturity date of December 31, 2025 and bear interest, payable quarterly, at the rate of 6.25% per annum until January 1, 2021. On that date, the interest rate will be adjusted to float at an annual rate equal to the prevailing three-month LIBOR rate plus 464 basis points ( 4.64% ) until maturity. The debentures include a right of prepayment, without penalty, on or after December 14, 2020 and, in certain limited circumstances, before that date. The indebtedness evidenced by the subordinated debentures, including principal and interest, is unsecured and subordinate and junior in right to payment to general and secured creditors of the Company and depositors and all other creditors of the Bank. The subordinated debentures have been structured to qualify as Tier 2 capital for regulatory purposes. Subordinated debentures totaled $9.9 million at September 30, 2017 and December 31, 2016 , which includes $121,000 and $145,000 , respectively, of remaining unamortized debt issuance costs at September 30, 2017 and December 31, 2016 . The debt issuance costs are being amortized over the expected life of the issue. The effective interest rate of the subordinated debentures is 6.67% .

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Accounting guidance establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1 : Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 : Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability. Level 3 : Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported with little or no market activity). An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. For financial assets measured at fair value on a recurring basis, the fair value measurements by level within the fair value hierarchy used at September 30, 2017 and December 31, 2016 are as follows: Description (Level 1) Quoted Prices in Active Markets for Identical Assets (Level 2) Significant Other Observable Inputs (Level 3) Significant Unobservable Inputs Total (in thousands) At September 30, 2017: Securities available for sale: U.S. Government agency securities $ — $ 7,846 $ — $ 7,846 Municipal securities — 504 — 504 GSE – residential mortgage-backed securities — 8,856 — 8,856 U.S. Government collateralized residential mortgage obligations — 7,962 — 7,962 Corporate debt securities, primarily financial institutions — 2,442 — 2,442 CRA mutual fund 2,451 — — 2,451 Total securities available for sale $ 2,451 $ 27,610 $ — $ 30,061 Description (Level 1) Quoted Prices in Active Markets for Identical Assets (Level 2) Significant Other Observable Inputs (Level 3) Significant Unobservable Inputs Total (in thousands) At December 31, 2016: Securities available for sale: U.S. Government agency securities $ — $ 8,413 $ — $ 8,413 Municipal securities — 503 — 503 GSE – residential mortgage-backed securities — 11,255 — 11,255 U.S. Government collateralized residential mortgage obligations — 9,537 — 9,537 Corporate debt securities, primarily financial institutions — 2,359 — 2,359 CRA mutual fund 2,397 — — 2,397 Total securities available for sale $ 2,397 $ 32,067 $ — $ 34,464 As of September 30, 2017 and December 31, 2016 , there were no securities available for sale measured at fair value on a recurring basis using significant unobservable inputs (Level 3). For assets measured at fair value on a nonrecurring basis, the fair value measurements by level within the fair value hierarchy used at September 30, 2017 and December 31, 2016 are as follows: Description (Level 1) Quoted Prices in Active Markets for Identical Assets (Level 2) Significant Other Observable Inputs (Level 3) Significant Unobservable Inputs Total (in thousands) At September 30, 2017: Impaired loans, net of partial charge-offs $ — $ — $ 248 $ 248 At December 31, 2016: Impaired loans with an allowance recorded $ — $ — $ 496 $ 496 OREO — — 259 259 The Company’s policy is to recognize transfers between levels as of the beginning of the period. There were no transfers between Levels 1, 2 and 3 for the three and nine months ended September 30, 2017 and 2016 . The following valuation techniques were used to measure fair value of assets in the tables above: • Impaired loans – Impaired loans measured at fair value are those loans in which the Company has measured impairment generally based on the fair value of the loan’s collateral. This method of fair value measurement is used on all of the Company’s impaired loans. Fair value is generally determined based upon either independent third party appraisals of the properties or discounted cash flows based upon the expected proceeds. The appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. At September 30, 2017 , there were no loans that received a discount. At December 31, 2016 , two loans received a 5.0% discount to their appraised values. At September 30, 2017 , there were no liquidation expenses. At December 31, 2016 , the liquidation expenses were 5.0% (weighted average of 5.0% ). These assets are included as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. • OREO – Real estate properties acquired through, or in lieu of, loan foreclosure are carried at fair value less cost to sell. Fair value is based upon the appraised value of the collateral, adjusted by management for factors such as economic conditions and other market factors. During the third quarter of 2017 , the Company sold its only OREO property for a loss of $17,000 . At December 31, 2016 , the discount and liquidation expenses for collateral adjustments to our one OREO property was 5.95% . These assets are included in Level 3 fair value based upon the lowest level of input that is significant to the fair value measurement. At December 31, 2016 , OREO totaling $259,000 was acquired by deed in lieu of foreclosure and was carried at fair value less estimated selling costs based on current appraisals. At September 30, 2017 , the Company had no residential real estate properties held in OREO. At September 30, 2017 , there were two residential mortgage loan secured by real estate in the amount of $596,000 that were in process of foreclosure. At December 31, 2016 , the Company initiated foreclosure proceedings on one residential mortgage loan secured by real estate in the amount of $532,000 . The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of the Company’s assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company’s disclosures and those of other companies may not be meaningful. The following methods and assumptions were used to estimate the fair values of the Company’s financial instruments at September 30, 2017 and December 31, 2016 : Cash and Cash Equivalents (carried at cost ): The carrying amounts reported in the balance sheet for cash and short-term instruments approximate those assets’ fair values. Securities : The fair value of securities available-for-sale (carried at fair value) and held to maturity (carried at amortized cost) are determined by obtaining quoted market prices on nationally recognized securities exchanges (Level 1), or matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices. For certain securities which are not traded in active markets or are subject to transfer restrictions, valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence (Level 3). At September 30, 2017 and December 31, 2016 , there were no Level 3 securities. Restricted Investments (carried at cost) : The carrying amount of restricted investment in Federal Home Loan Bank stock, Atlantic Community Bancshares, Inc. stock and Solomon Hess SBA Loan Fund approximates fair value, and considers the limited marketability of such securities. Loans Held for Sale: Loans held for sale are carried at the lower of aggregate cost or estimated fair value, less costs to sell. The fair value of these loans are equal to the contractual sales price. Loans Receivable (carried at cost) : The fair values of loans, excluding collateral dependent impaired loans, are estimated using discounted cash flow analyses, using market rates at the balance sheet date that reflect the credit and interest rate-risk inherent in the loans, including liquidity. Projected future cash flows are calculated based upon contractual maturity or call dates, projected repayments and prepayments of principal. The valuation of the loan portfolio reflects discounts that the Company believes are consistent with transactions occurring in the marketplace for both performing and distressed loan types. The carrying value that fair value is compared to is net of the allowance for loan losses and other associated premiums and discounts. Generally, for variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Due to the significant judgment involved in evaluating credit quality risk, loans are classified within Level 3 of the fair value hierarchy. Accrued Interest Receivable and Payable (carried at cost) : The carrying amount of accrued interest receivable and accrued interest payable approximates its fair value. Deposit Liabilities (carried at cost) : The fair values disclosed for demand deposits (e.g., interest and noninterest checking, passbook savings and money market accounts) are, by definition, equal to the amount payable on demand at the reporting date, (i.e., their carrying amounts). Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market on certificates to a schedule of aggregated expected monthly maturities on time deposits. Securities Sold Under Agreements to Repurchase (carried at cost) : The carrying amounts of these short-term borrowings approximate their fair values. FHLB and Other Borrowing (carried at cost) : Fair values of FHLB advances are estimated using discounted cash flow analysis, based on quoted prices for new FHLB advances with similar credit risk characteristics, terms and remaining maturity. These prices obtained from this active market represent a market value that is deemed to represent the transfer price if the liability were assumed by a third party. Subordinated Debentures (carried at cost): The fair value of subordinated debentures is estimated by using a discounted cash flow analysis that, at September 30, 2017 and December 31, 2016 , applies a 4.59% and 4.64% credit spread, respectively, plus the U.S. Treasury rate (all-in issue spread) to the time remaining until the issue’s call option date. Off-Balance Sheet Financial Instruments (disclosed at cost) : Fair values for the Company’s off-balance sheet financial instruments (lending commitments and letters of credit) are based on fees currently charged in the market to enter into similar agreements, taking into account, the remaining terms of the agreements and the counterparties’ credit standing. The fair values of such fees are not material at September 30, 2017 and December 31, 2016 . The estimated fair values of the Company’s financial instruments at September 30, 2017 and December 31, 2016 were as follows: Fair Value Measurements at September 30, 2017 (in thousands) Carrying Amount Estimated Fair Value (Level 1) Quoted Prices in Active Markets for Identical Assets (Level 2) Significant Other Observable Inputs (Level 3) Significant Unobservable Inputs Financial assets: Cash and cash equivalents $ 46,303 $ 46,303 $ 46,303 $ — $ — Securities available for sale 30,061 30,061 2,451 27,610 — Securities held to maturity 57,058 57,719 — 57,719 — Restricted investments 5,522 5,522 — — 5,522 Loans held for sale 1,082 1,130 — — 1,130 Loans receivable, net 805,855 809,008 — — 809,008 Accrued interest receivable 2,313 2,313 — 497 1,816 Financial liabilities: Deposits 821,872 821,432 — 821,432 — Securities sold under agreements to repurchase 22,576 22,576 — 22,576 — FHLB and other borrowings 30,300 30,170 — 30,170 — Subordinated debt 9,879 9,879 — 9,879 — Accrued interest payable 114 114 — 114 — Fair Value Measurements at December 31, 2016 (in thousands) Carrying Amount Estimated Fair Value (Level 1) Quoted Prices in Active Markets for Identical Assets (Level 2) Significant Other Observable Inputs (Level 3) Significant Unobservable Inputs Financial assets: Cash and cash equivalents $ 42,077 $ 42,077 $ 42,077 $ — $ — Securities available for sale 34,464 34,464 2,397 32,067 — Securities held to maturity 57,843 57,284 — 57,284 — Restricted investments 4,805 4,805 — — 4,805 Loans held for sale 4,537 4,698 — — 4,698 Loans receivable, net 743,527 740,910 — — 740,910 Accrued interest receivable 2,234 2,234 — 621 1,613 Financial liabilities: Deposits 776,567 776,404 — 776,404 — Securities sold under agreements to repurchase 19,915 19,915 — 19,915 — FHLB and other borrowings 25,300 25,363 — 25,363 — Subordinated debt 9,855 9,827 — 9,827 — Accrued interest payable 100 100 — 100 —

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements include the accounts of Two River Bancorp (the “Company”), a bank holding company, and its wholly-owned subsidiary, Two River Community Bank (“Two River” or the “Bank”); Two River’s wholly-owned subsidiaries, TRCB Investment Corporation and TRCB Holdings Eight LLC. All inter-company balances and transactions have been eliminated in the consolidated financial statements. 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 pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), including the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for full year financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal, recurring nature. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 . These consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 24, 2017 (the “ 2016 Form 10-K”). For a description of the Company’s significant accounting policies, refer to Note 1 of the Notes to Consolidated Financial Statements in the 2016 Form 10-K. The Company has evaluated events and transactions occurring subsequent to the balance sheet date of September 30, 2017 for items that should potentially be recognized or disclosed in these consolidated financial statements.
New Accounting Standards	NEW ACCOUNTING STANDARDS ASU 2014-09: In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers. Subsequently, the FASB issued guidance codified in ASC 606, "Revenue from Contracts with Customers," which amends the guidance in former ASC 605 "Revenue Recognition." The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This will be achieved in a five-step process. Enhanced disclosures also will be required. This guidance is effective on a retrospective basis, either to each reporting period presented or with the cumulative effect of initially applying this guidance recognized at the date of initial application for annual reporting periods, including interim reporting periods within those annual reporting periods, beginning after December 15, 2017. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company's revenue is comprised of net interest income and non-interest income. The scope of the guidance excludes net interest income. Accordingly, the majority of our revenues will not be affected. The Company has prepared the initial review of its contracts and other agreements that are within the scope of this guidance and will complete the process pending review of additional guidance. While we are continuing to assess all potential impacts these standards will have on our financial position and results of operations, our initial conclusions indicate that these standards will not materially change the timing of revenue recognition. The Company will adopt the requirements of the new standard on January 1, 2018, utilizing the modified retrospective transition method. Upon adoption, the Company will recognize the cumulative effect of adopting this ASU as an adjustment to the opening balance of retained earnings. Prior periods will not be retrospectively adjusted. The Company continues to evaluate the impact of the guidance on disclosures. ASU 2016-01: In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income; provides for a practicability exception election for equity investments without readily determinable fair values; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; eliminates the requirement for nonpublic business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial assets on the balance sheet or the accompanying notes to the financial statements and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU 2016-01 will have on its statement of financial position or financial statement disclosures. ASU 2016-02: In February 2016, the FASB issued ASU No. 2016-02, Leases. From the lessee’s perspective, the new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement for a lessee. From the lessor’s perspective, the new standard requires a lessor to classify leases as either sales-type, finance or operating. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as a financing. If the lessor doesn’t convey risks and rewards or control, an operating lease results. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. A modified retrospective transition approach is required for lessors for sales-type, direct financing, and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company has determined that the provisions of ASU 2016-02 will result in an increase in assets to recognize the present value of the lease obligations with a corresponding increase in liabilities, however, the Company does not expect this to have a material impact on its financial position, results of operations or cash flows. ASU 2016-13: In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326) . This ASU requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Entities will now use forward-looking information to better form their credit loss estimates. The ASU also requires enhanced disclosures to help financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. For public entities that are SEC filers, this ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. For public entities that are not SEC filers, this ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For non-public entities, this ASU is effective for fiscal years beginning after December 15, 2020, and for interim periods within fiscal years beginning after December 15, 2021. Early application will be permitted for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. While the Company is currently evaluating the provisions of ASU 2016-13 to determine the potential impact the new standard will have on its consolidated financial statements, it has taken steps to prepare for the implementation when it becomes effective, such as forming an internal task force, gathering pertinent data, consulting with outside professionals and evaluating its current IT systems. ASU 2016-15: In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . ASU 2016-15 addresses changes to reduce the presentation diversity of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs, settlement of certain debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, and distributions received from equity method investees. The guidance becomes effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. An entity that elects early adoption must adopt all of the amendments in the same period. The new standard will be applied retrospectively, but may be applied prospectively if retrospective application would be impracticable. The Company is currently evaluating the new guidance and has not determined the impact this standard may have on its consolidated statement of cash flows. ASU 2016-18: In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 was issued to address divergence in the way restricted cash is classified and presented. The amendments in the update require that a statement of cash flows explain the change during a reporting period in the total of cash, cash equivalents, and amounts generally described as restricted cash and restricted cash equivalents. The amendments in this update apply to entities that have restricted cash or restricted cash equivalents and are required to present a statement of cash flows under Topic 230. The amendment says that transfers between cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents are not part of the entity's operating, investing, and financing activities. For public business entities, ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact of the adoption of ASU 2016-18 on its consolidated financial statements. ASU 2017-04: In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350) . ASU 2017-04 removes Step 2 from the goodwill impairment test. Under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. For public entities that are SEC filers, this ASU is effective for its annual, or any goodwill impairment tests in fiscal years, beginning after December 15, 2019. For public entities that are not SEC filers, this ASU is effective for its annual, or any goodwill impairment tests in fiscal years, beginning after December 15, 2020. For non-public entities, this ASU is effective for its annual, or any goodwill impairment tests in fiscal years, beginning after December 15, 2021. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the new guidance but has determined that this standard should not have a material impact on its consolidated financial statements. ASU 2017-09: In May 2017, the FASB issued ASU No. 2017-09, “Stock Compensation, Scope of Modification Accounting.” This ASU clarifies when changes to the terms of conditions of a share-based payment award must be accounted for as modifications. Companies will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. The new guidance should reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications, as the guidance will allow companies to make certain non-substantive changes to awards without accounting for them as modifications. It does not change the accounting for modifications. ASU No. 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017; early adoption is permitted. ASU No. 2017-09 is not expected to have a material impact on the Company’s consolidated financial statements.
