Accounting Policies [Abstract]
Summary of significant accounting policies	1. Summary of significant accounting policies: Nature of Operations Riverview Financial Corporation, (the “Company”), a bank holding company incorporated under the laws of Pennsylvania, provides a full range of financial services through its wholly-owned subsidiary, Riverview Bank (the “Bank”). The Company services its retail and commercial customers through 17 full-service community banking offices located within Berks, Dauphin, Northumberland, Perry, Schuylkill and Somerset Counties in Pennsylvania. Basis of presentation: The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP’) for interim financial information and with the instructions to Form 10-Q Article 10-01 Regulation S-X. 10-K, The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates that are particularly susceptible to material change in the near term relate to the determination of the allowance for loan losses, fair value of financial instruments, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the valuation of deferred tax assets, determination of other-than-temporary impairment losses on securities and impairment of goodwill. Actual results could differ from those estimates.

Earnings per share

Earnings per share	3 Months Ended

Earnings Per Share [Abstract]
Earnings per share	3. Earnings per share: Basic earnings per share represent distributed and undistributed earnings allocated to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. The following table provides a reconciliation between the computation of basic earnings per share and diluted earnings per share for the three months ended March 31, 2017 and 2016: Three Months ended March 31, Income Numerator Common Shares Denominator EPS 2017: Basic $ (405 ) 3,454,704 $ (0.12 ) Dilutive effect of potential common stock options Diluted $ (405 ) 3,454,704 $ (0.12 ) 2016: Basic $ 753 3,206,501 $ 0.23 Dilutive effect of potential common stock options 15,504 Diluted $ 753 3,222,005 $ 0.23 Approximately 43,000 outstanding stock options for the three months ended March 31, 2017 were excluded from the diluted earnings per share calculation because their effect was antidilutive, while there were 25,300 outstanding stock options for the three months ended March 31, 2016 that were excluded from the diluted earnings per share calculation because of their antidilutive effect. On January 20, 2017, Riverview announced that it has entered into agreements with accredited investors and qualified institutional buyers to raise approximately $17.0 million in common and preferred equity, before expenses, through the private placement of 269,885 shares of its no par value common stock at a price of $10.50 per share and 1,348,809 shares of a newly created Series A convertible, perpetual preferred stock (the “Series A preferred stock”) at a price of $10.50 per share. The Series A preferred stock has the following terms: • Dividends: Holders of the Series A preferred stock are entitled to receive dividends when, as, and if declared by the Company’s board of directors, in the same per share amount as paid on the number of shares of common stock with respect to the number of shares of common stock into which the shares of Series A preferred stock would be converted in accordance with the Articles of Amendment, and no dividends would be payable on the common stock unless a dividend identical to that paid on the common stock is payable at the same time on the Series A preferred stock on an as-converted basis. • Conversion: Each share of Series A preferred stock will automatically convert into one share of non-voting common stock effective as of the close of business on the date that the Company obtains shareholder approval for and files an amendment to the Articles of Incorporation to authorize a class of non-voting common stock. Unless the shares of Series A preferred stock have previously been converted into shares of non-voting common stock as described above, each share of Series A preferred stock will automatically convert into one share of voting common stock upon a “Permissible Transfer” of such shares of Series A preferred stock to a non-affiliate of such holder or may be converted into one share of voting common stock at any time, provided that, upon such conversion, the holder and its affiliates will not own more than 9.9% of the Company’s voting securities, or such greater amount as shall have been indicated to be non-objectionable to bank regulatory authorities. • Priority: The Series A preferred stock will rank, as to payments of dividends and distribution of assets upon dissolution, liquidation or winding up of the Company with the common stock pro rata on an as-converted basis. • Voting: Holders of Series A preferred stock will have no voting rights except as may be required by law. If the holders of Series A preferred stock are entitled by law to vote as a single class with the holders of outstanding shares of common stock, each share of Series A preferred stock shall be entitled to a number of votes equal to the number of shares of common stock into which such share is convertible. • Preemptive Rights: Holders of Series A preferred stock have pre-emptive rights to maintain their percent ownership with respect to stock issued for capital raising and financing purposes. • Redemption: The Series A preferred stock will not be redeemable by either the Company or by the holder. The contractual terms of the outstanding Series A preferred stock provide holders with contractual rights and obligations to participate in the earnings and share in the losses of the Company on a basis that is objectively determinable and, accordingly, the Company applied the two-class method of computing basic earnings per common share. The additional capital allowed Riverview to announce on April 20, 2017, the execution of a definitive business combination agreement to form a strategic partnership with CBT Financial Corp. This action will form a combined community banking franchise with approximately $1.2 billion of assets and will provide enhanced products and services through 33 banking locations covering 12 Pennsylvania counties.

Loans are individually analyzed for credit risk by classifying them within the Company’s internal risk rating system. The Company’s risk rating classifications are defined as follows: • Pass- A loan to borrowers with acceptable credit quality and risk that is not adversely classified as Substandard, Doubtful, Loss nor designated as Special Mention. • Special Mention- A loan that has potential weaknesses that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the institution’s credit position at some future date. Special Mention loans are not adversely classified since they do not expose the Company to sufficient risk to warrant adverse classification. • Substandard- A loan that is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the bank will sustain some loss if the deficiencies are not corrected. • Doubtful – A loan classified as Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make the collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. • Loss- A loan classified as Loss is considered uncollectible and of such little value that its continuance as bankable loan is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future. The following tables present the major classification of loans summarized by the aggregate pass rating and the classified ratings of special mention, substandard and doubtful within the Company’s internal risk rating system at March 31, 2017 and December 31, 2016: March 31, 2017 Pass Special Mention Substandard Doubtful Total Commercial $ 50,233 $ 1,357 $ 1,670 $ 53,260 Real estate: Construction 8,439 8,439 Commercial 256,199 7,627 3,647 267,473 Residential 127,410 28 1,395 128,833 Consumer 6,476 6,476 Total $ 448,757 $ 9,012 $ 6,712 $ 464,481 December 31, 2016: Pass Special Mention Substandard Doubtful Total Commercial $ 47,765 $ 1,604 $ 1,797 $ 51,166 Real estate: Construction 8,605 8,605 Commercial 200,636 8,063 3,851 212,550 Residential 129,320 28 1,526 130,874 Consumer 6,148 6,148 Total $ 392,474 $ 9,695 $ 7,174 $ 409,343 Information concerning nonaccrual loans by major loan classification at March 31, 2017 and December 31, 2016 is summarized as follows: March 31, 2017 December 31, 2016 Commercial $ 246 $ 356 Real estate: Construction Commercial 584 359 Residential 895 671 Consumer Total $ 1,725 $ 1,386 The major classifications of loans by past due status at March 31, 2017 and December 31, 2016 are summarized as follows: March 31, 2017 30-59 Days Past Due 60-89 Days Past Due Greater than 90 Days Total Past Due Current Total Loans Loans > 90 Days and Accruing Commercial $ 487 $ 1,136 $ 145 $ 1,768 $ 51,492 $ 53,260 $ 20 Real estate: Construction 8,439 8,439 Commercial 368 54 245 667 266,806 267,473 Residential 2,372 430 660 3,462 125,371 128,833 169 Consumer 17 1 18 6,458 6,476 Total $ 3,244 $ 1,621 $ 1,050 $ 5,915 $ 458,566 $ 464,481 $ 189 December 31, 2016 30-59 Days Past Due 60-89 Days Past Due Greater than 90 Days Total Past Due Current Total Loans Loans > 90 Days and Accruing Commercial $ 580 $ $ 214 $ 794 $ 50,372 $ 51,166 $ Real estate: Construction 22 22 8,583 8,605 Commercial 784 97 11 892 211,658 212,550 Residential 905 256 592 1,753 129,121 130,874 357 Consumer 6 2 8 6,140 6,148 2 Total $ 2,297 $ 353 $ 819 $ 3,469 $ 405,874 $ 409,343 $ 359 The following tables summarize information concerning impaired loans as of and for the three months ended March 31, 2017 and March 31, 2016, and as of and for the year ended, December 31, 2016 by major loan classification: This Quarter March 31, 2017 Recorded Investment Unpaid Principal Balance Related Allowance Average Recorded Investment Interest Income Recognized With no related allowance: Commercial $ 730 $ 730 $ $ 767 $ 8 Real estate: Construction Commercial 3,165 3,165 3,230 36 Residential 2,447 2,585 2,641 33 Consumer Total 6,342 6,480 6,638 77 With an allowance recorded: Commercial 120 120 1 122 Real estate: Construction Commercial 867 867 160 709 6 Residential Consumer Total 987 987 161 831 6 Commercial 850 850 1 889 8 Real estate: Construction Commercial 4,032 4,032 160 3,939 42 Residential 2,447 2,585 2,641 33 Consumer Total $ 7,329 $ 7,467 $ 161 $ 7,469 $ 83 For the Year Ended December 31, 2016 Recorded Investment Unpaid Principal Balance Related Allowance Average Recorded Investment Interest Income Recognized With no related allowance: Commercial $ 225 $ 225 $ $ 225 $ Real estate: Construction Commercial 3,094 3,094 3,168 147 Residential 2,515 2,652 2,747 130 Consumer Total 5,834 5,971 6,140 277 With an allowance recorded: Commercial 741 741 8 761 30 Real estate: Construction Commercial 830 830 140 840 Residential Consumer Total 1,571 1,571 148 1,601 30 Commercial 966 966 8 986 30 Real estate: Construction Commercial 3,924 3,924 140 4,008 147 Residential 2,515 2,652 2,747 130 Consumer Total $ 7,405 $ 7,542 $ 148 $ 7,741 $ 307 This Quarter March 31, 2016 Recorded Investment Unpaid Principal Balance Related Allowance Average Recorded Investment Interest Income Recognized With no related allowance: Commercial $ 898 $ 2,021 $ $ 1,395 $ 7 Real estate: Construction Commercial 3,997 4,004 4,016 45 Residential 2,781 2,918 3,015 34 Consumer Total 7,676 8,943 8, 426 86 With an allowance recorded: Commercial 135 135 1 136 Real estate: Construction Commercial 401 401 7 400 Residential 120 120 33 121 1 Consumer Total 656 656 41 657 1 Commercial 1,033 2,156 1 1,531 7 Real estate: Construction Commercial 4,398 4,405 7 4,416 45 Residential 2,901 3,038 33 3,136 35 Consumer Total $ 8,332 $ 9,599 $ 41 $ 9,083 $ 87 For the three months ended March 31, interest income, related to impaired loans, would have been $26 in 2017 and $47 in 2016 had the loans been current and the terms of the loans not been modified. Included in the commercial loan and commercial and residential real estate categories are troubled debt restructurings that are classified as impaired. Troubled debt restructurings totaled $6,021 at March 31, 2017, $6,208 at December 31, 2016 and $6,998 at March 31, 2016. Troubled debt restructured loans are loans with original terms, interest rate, or both, that have been modified as a result of a deterioration in the borrower’s financial condition and a concession has been granted that the Company would not otherwise consider. Unless on nonaccrual, interest income on these loans is recognized when earned, using the interest method. The Company offers a variety of modifications to borrowers that would be considered concessions. The modification categories offered generally fall within the following categories: • Rate Modification - A modification in which the interest rate is changed to a below market rate. • Term Modification - A modification in which the maturity date, timing of payments or frequency of payments is changed. • Interest Only Modification - A modification in which the loan is converted to interest only payments for a period of time. • Payment Modification - A modification in which the dollar amount of the payment is changed, other than an interest only modification described above. • Combination Modification - Any other type of modification, including the use of multiple categories above. There was one loan modified as a troubled debt restructuring for the three months ended March 31, 2017 for $29. There were no loans modified as troubled debt restructurings for the three months ended March 31, 2016. During the three months ending March 31, 2017, there were four defaults on loans restructured, totaling $1,229. During the three months ending March 31, 2016, there were no defaults on loans restructured. Purchased loans are initially recorded at their acquisition date fair values. The carryover of the allowance for loan losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for purchased loans are based on a cash flow methodology that involves assumptions and judgments as to credit risk, default rates, loss severity, collateral values, discount rates, payment speeds, and prepayment risk. As part of its acquisition due diligence process, the Bank reviews the acquired institution’s loan grading system and the associated risk rating for loans. In performing this review, the Bank considers cash flows, debt service coverage, delinquency status, accrual status, and collateral for the loan. This process allows the Bank to clearly identify the population of acquired loans that had evidence of deterioration in credit quality since origination and for which it was probable, at acquisition, that the Bank would be unable to collect all contractually required payments. All such loans identified by the Bank are considered to be within the scope of ASC 310-30, As a result of the merger with Citizens, effective December 31, 2015, the Bank identified ten purchased credit impaired (“PCI”) loans. As part of the consolidation with Union, effective November 1, 2013, the Bank identified fourteen PCI loans. For all PCI loans, the excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loan. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable non-accretable non-accretable non-accretable For purchased loans that are not deemed impaired at acquisition, credit discounts representing principal losses expected over the life of the loans are a component of the initial fair value, and the discount is accreted to interest income over the life of the asset. Subsequent to the purchase date, the method used to evaluate the sufficiency of the credit discount is similar to originated loans, and if necessary, additional reserves are recognized in the allowance for loan losses. The following is a summary of the loans acquired in the Union merger as of November 1, 2013, the date of the consolidation: Purchased Credit Impaired Loans Purchased Non- Impaired Loans Total Purchased Loans Union Contractually required principal and interest at acquisition $ 10,290 $ 92,704 $ 102,994 Contractual cash flows not expected to be collected (5,487 ) (9,492 ) (14,979 ) Expected cash flows at acquisition 4,803 83,212 88,015 Interest component of expected cash flows (386 ) (12,278 ) (12,664 ) Basis in acquired loans at acquisition – estimated fair value $ 4,417 $ 70,934 $ 75,351 The unpaid principal balances and the related carrying amount of Union acquired loans as of March 31, 2017 and December 31, 2016 were as follows: March 31 2017 December 31, 2016 Credit impaired purchased loans evaluated individually for incurred credit losses Outstanding balance $ 785 $ 793 Carrying Amount 458 463 Other purchased loans evaluated collectively for incurred credit losses Outstanding balance 36,111 38,901 Carrying Amount 35,347 38,077 Total Purchased Loans Outstanding balance 36,896 39,694 Carrying Amount $ 35,805 $ 38,540 As of the indicated dates, the changes in the accretable discount related to the purchased credit impaired loans were as follows: Three Months Ended March 31, 2017 March 31, 2016 Balance – beginning of period $ 164 $ 307 Accretion recognized during the period (13 ) (94 ) Net reclassification from non-accretable 7 46 Balance – end of period $ 158 $ 259 The following is a summary of the loans acquired in the Citizens’ merger as of December 31, 2015, the effective date of the merger: Purchased Credit Impaired Loans Purchased Non- Impaired Loans Total Purchased Loans Citizens Contractually required principal and interest at acquisition $ 894 $ 81,780 $ 82,674 Contractual cash flows not expected to be collected (237 ) (13,517 ) (13,754 ) Expected cash flows at acquisition 657 68,263 68,920 Interest component of expected cash flows (217 ) (10,841 ) (11,058 ) Basis in acquired loans at acquisition – estimated fair value $ 440 $ 57,422 $ 57,862 The unpaid principal balances and the related carrying amount of Citizens acquired loans as of March 31, 2017 and December 31, 2016 were as follows: March 31, December 31, Credit impaired purchased loans evaluated individually for incurred credit losses Outstanding balance $ 512 $ 608 Carrying Amount 343 424 Other purchased loans evaluated collectively for incurred credit losses Outstanding balance 43,837 45,842 Carrying Amount 43,596 45,593 Total Purchased Loans Outstanding balance 44,349 46,450 Carrying Amount $ 43,939 $ 46,017 As of the indicated dates, the changes in the accretable discount related to the purchased credit impaired loans were as follows: March 31, March 31, Balance – beginning of period $ 206 $ 217 Accretion recognized during the period (10 ) (6 ) Net reclassification from non-accretable (31 ) 2 Balance – end of period $ 165 $ 213 The Company is a party to financial instruments with off-balance Off-balance off-balance

Fair Value Disclosures [Abstract]
Fair value estimates	7. Fair value estimates: The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosure under GAAP. Fair value estimates are calculated without attempting to estimate the value of anticipated future business and the value of certain assets and liabilities that are not considered financial. Accordingly, such assets and liabilities are excluded from disclosure requirements. In accordance with FASB ASC 820, “Fair Value Measurements and Disclosures,” fair value is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets. In many cases, these values cannot be realized in immediate settlement of the instrument. Current fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction that is not a forced liquidation or distressed sale between participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. In accordance with GAAP, the Company groups its assets and liabilities generally measured at fair value into three levels based on market information or other fair value estimates in which the assets and liabilities are traded or valued and the reliability of the assumptions used to determine fair value. These levels include: • Level 1: Unadjusted quoted prices of identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. An asset’s or liability’s placement in the fair value hierarchy is based on the lowest level of input that is significant to the fair value estimate. The following methods and assumptions were used by the Company to calculate fair values and related carrying amounts of financial instruments: Cash and cash equivalents: Investment securities: Loans held for sale: Net loans: re-price non-impaired Accrued interest receivable: Restricted equity securities: Deposits: low-cost Short-term borrowings: Long-term debt: Accrued interest payable: Off-balance The majority of commitments to extend credit, unused portions of lines of credit and standby letters of credit carry current market interest rates if converted to loans. Because such commitments are generally unassignable by either the Company or the borrower, they only have value to the Company and the borrower. None of the commitments are subject to undue credit risk. The estimated fair values of off-balance off-balance Assets and liabilities measured at fair value on a recurring basis at March 31, 2017 and December 31, 2016 are summarized as follows: Fair Value Measurement Using March 31, 2017 Amount Quoted Prices in Significant (Level 2) Significant (Level 3) U.S. Treasury securities $ 5,054 $ 5,054 State and Municipals: Taxable 42,564 42,564 Tax-exempt 5,741 5,741 Mortgage-backed securities: U.S. Government agencies 1,725 1,725 U.S. Government-sponsored enterprises 8,635 8,635 Corporate debt obligations 8,832 8,832 Equity securities, financial services 190 $ 190 Total $ 72,741 $ 190 $ 72,551 Fair Value Measurement Using December 31, 2016 Amount Quoted Prices in Significant Other Observable (Level 2) Significant (Level 3) U.S. Treasury securities $ 5,021 $ 5,021 State and municipals: Taxable 42,394 42,394 Tax-exempt 5,674 5,674 Mortgage-backed securities: U.S. Government agencies 1,890 1,890 U.S. Government-sponsored enterprises 8,896 8,896 Corporate debt obligations 9,050 9,050 Equity securities, financial services 188 $ 188 Total $ 73,113 $ 188 $ 72,925 Assets and liabilities measured at fair value on a nonrecurring basis at March 31, 2017 and December 31, 2016 are summarized as follows: Fair Value Measurement Using March 31, 2017 Amount (Level 1) (Level 2) (Level 3) Loans held for sale $ 522 $ 522 Other real estate owned 561 $ 561 Impaired loans, net of related allowance 827 827 Total $ 1,910 $ 522 $ 1,388 Fair Value Measurement Using December 31, 2016 Amount (Level 1) (Level 2) (Level 3) Loans held for sale $ 652 $ 652 Other real estate owned 625 $ 625 Impaired loans, net of related allowance 1,424 1,424 Total $ 2,701 $ 652 $ 2,049 Fair values of impaired loans are based on 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. Fair value of other real estate owned is generally determined through independent appraisals of the underlying collateral, which generally include various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range and weighted average of liquidation expenses and other appraisal adjustments are presented as a percent of the appraisal.

Basis of presentation	Basis of presentation: The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP’) for interim financial information and with the instructions to Form 10-Q Article 10-01 Regulation S-X. 10-K, The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates that are particularly susceptible to material change in the near term relate to the determination of the allowance for loan losses, fair value of financial instruments, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the valuation of deferred tax assets, determination of other-than-temporary impairment losses on securities and impairment of goodwill. Actual results could differ from those estimates.
