Basis of Accounting [Text Block]	1. BASIS OF INTERIM PRESENTATION The consolidated financial information included herein, with the exception of the consolidated balance sheet dated December 31, 2015, is unaudited. Such information reflects all adjustments (consisting solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations, comprehensive income, cash flows and changes in stockholders’ equity for the interim periods; however, the information does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for a complete set of financial statements. Certain 2015 information has been reclassified for consistency with the 2016 presentation. Operating results reported for the three-month and nine-month periods ended September 30, 2016 might not be indicative of the results for the year ending December 31, 2016.

Fair Value Disclosures [Text Block]	5. FAIR VALUE MEASUREMENTS AND FAIR VALUES OF FINANCIAL INSTRUMENTS The Corporation measures certain assets at fair value. Fair value is defined as the price that would be received to sell an asset in an orderly transaction between market participants at the measurement date. FASB Accounting Standards Codification (ASC) topic 820, “Fair Value Measurements and Disclosures” establishes a framework for measuring fair value that includes a hierarchy used to classify the inputs used in measuring fair value. The hierarchy prioritizes the inputs used in determining valuations into three levels. The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. The levels of the fair value hierarchy are as follows: Level 1 – Fair value is based on unadjusted quoted prices in active markets that are accessible to the Corporation for identical assets. These generally provide the most reliable evidence and are used to measure fair value whenever available. Level 2 – Fair value is based on significant inputs, other than Level 1 inputs, that are observable either directly or indirectly for substantially the full term of the asset through corroboration with observable market data. Level 2 inputs include quoted market prices in active markets for similar assets, quoted market prices in markets that are not active for identical or similar assets and other observable inputs. Level 3 – Fair value is based on significant unobservable inputs. Examples of valuation methodologies that would result in Level 3 classification include option pricing models, discounted cash flows and other similar techniques. CITIZENS & NORTHERN CORPORATION – FORM 10-Q The Corporation monitors and evaluates available data relating to fair value measurements on an ongoing basis and recognizes transfers among the levels of the fair value hierarchy as of the date of an event or change in circumstances that affects the valuation method chosen. Examples of such changes may include the market for a particular asset becoming active or inactive, changes in the availability of quoted prices, or changes in the availability of other market data. At September 30, 2016 and December 31, 2015, assets measured at fair value and the valuation methods used are as follows: September 30, 2016 Quoted Prices Other in Active Observable Unobservable Total Markets Inputs Inputs Fair (In Thousands) (Level 1) (Level 2) (Level 3) Value Recurring fair value measurements AVAILABLE-FOR-SALE SECURITIES: Obligations of U.S. Government agencies $ 0 $ 9,747 $ 0 $ 9,747 Obligations of states and political subdivisions: Tax-exempt 0 121,283 0 121,283 Taxable 0 33,672 0 33,672 Mortgage-backed securities issued or guaranteed by U.S. Government agencies or sponsored agencies: Residential pass-through securities 0 62,187 0 62,187 Residential collateralized mortgage obligations 0 165,719 0 165,719 Commercial mortgage-backed securities 0 16,112 0 16,112 Total debt securities 0 408,720 0 408,720 Marketable equity securities 1,080 0 0 1,080 Total available-for-sale securities 1,080 408,720 0 409,800 Servicing rights 0 0 1,208 1,208 Total recurring fair value measurements $ 1,080 $ 408,720 $ 1,208 $ 411,008 Nonrecurring fair value measurements Impaired loans with a valuation allowance $ 0 $ 0 $ 3,621 $ 3,621 Valuation allowance 0 0 (685 ) (685 ) Impaired loans, net 0 0 2,936 2,936 Foreclosed assets held for sale 0 0 2,321 2,321 Total nonrecurring fair value measurements $ 0 $ 0 $ 5,257 $ 5,257 CITIZENS & NORTHERN CORPORATION – FORM 10-Q December 31, 2015 Quoted Prices Other in Active Observable Unobservable Total Markets Inputs Inputs Fair (In Thousands) (Level 1) (Level 2) (Level 3) Value Recurring fair value measurements AVAILABLE-FOR-SALE SECURITIES: Obligations of U.S. Government agencies $ 0 $ 10,483 $ 0 $ 10,483 Obligations of states and political subdivisions: Tax-exempt 0 107,757 0 107,757 Taxable 0 34,597 0 34,597 Mortgage-backed securities issued or guaranteed by U.S. Government agencies or sponsored agencies: Residential pass-through securities 0 73,343 0 73343 Residential collateralized mortgage obligations 0 191,715 0 191,715 Collateralized debt obligations 0 9 0 9 Total debt securities 0 417,904 0 417,904 Marketable equity securities 2,386 0 0 2,386 Total available-for-sale securities 2,386 417,904 0 420,290 Servicing rights 0 0 1,296 1,296 Total recurring fair value measurements $ 2,386 $ 417,904 $ 1,296 $ 421,586 Nonrecurring fair value measurements Impaired loans with a valuation allowance $ 0 $ 0 $ 1,933 $ 1,933 Valuation allowance 0 0 (820 ) (820 ) Impaired loans, net 0 0 1,113 1,113 Foreclosed assets held for sale 0 0 1,260 1,260 Total nonrecurring fair value measurements $ 0 $ 0 $ 2,373 $ 2,373 Management’s evaluation and selection of valuation techniques and the unobservable inputs used in determining the fair values of assets valued using Level 3 methodologies include sensitive assumptions. Other market participants might use substantially different assumptions, which could result in calculations of fair values that would be substantially different than the amount calculated by management. At September 30, 2016 and December 31, 2015, quantitative information regarding significant techniques and inputs used for assets measured on a recurring basis using unobservable inputs (Level 3 methodologies) are as follows: Fair Value at 9/30/16 Valuation Unobservable Method or Value As of Asset (In Thousands) Technique Input(s) 9 /30/16 Servicing rights $ 1,208 Discounted cash flow Discount rate 10.00 % Rate used through modeling period Loan prepayment speeds 194.00 % Weighted-average PSA Servicing fees 0.25 % of loan balances 4.00 % of payments are late 5.00 % late fees assessed $ 1.94 Miscellaneous fees per account per month Servicing costs $ 6.00 Monthly servicing cost per account $ 24.00 Additional monthly servicing cost per loan on loans more than 30 days delinquent 1.50 % of loans more than 30 days delinquent 3.00 % annual increase in servicing costs CITIZENS & NORTHERN CORPORATION – FORM 10-Q Fair Value at 12/31/15 Valuation Unobservable Method or Value As of Asset (In Thousands) Technique Input(s) 12/31/15 Servicing rights $ 1,296 Discounted cash flow Discount rate 10.00 % Rate used through modeling period Loan prepayment speeds 146.00 % Weighted-average PSA Servicing fees 0.25 % of loan balances 4.00 % of payments are late 5.00 % late fees assessed $ 1.94 Miscellaneous fees per account per month Servicing costs $ 6.00 Monthly servicing cost per account $ 24.00 Additional monthly servicing cost per loan on loans more than 30 days delinquent 1.50 % of loans more than 30 days delinquent 3.00 % annual increase in servicing costs The fair value of servicing rights is affected by expected future interest rates. Increases (decreases) in future expected interest rates tend to increase (decrease) the fair value of the Corporation’s servicing rights because of changes in expected prepayment behavior by the borrowers on the underlying loans. Following is a reconciliation of activity for Level 3 assets measured at fair value on a recurring basis: (In Thousands) Three Months Ended Nine Months Ended Sept. 30, 2016 Sept. 30, 2015 Sept. 30, 2016 Sept. 30, 2015 Servicing rights balance, beginning of period $ 1,224 $ 1,209 $ 1,296 $ 1,281 Issuances of servicing rights 52 57 159 135 Unrealized (losses) gains included in earnings (68 ) 13 (247 ) (137 ) Servicing rights balance, end of period $ 1,208 $ 1,279 $ 1,208 $ 1,279 Loans are classified as impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Foreclosed assets held for sale consist of real estate acquired by foreclosure. For impaired commercial loans secured by real estate and foreclosed assets held for sale, estimated fair values are determined primarily using values from third-party appraisals. 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. At September 30, 2016 and December 31, 2015, quantitative information regarding significant techniques and inputs used for nonrecurring fair value measurements using unobservable inputs (Level 3 methodologies) are as follows: (In Thousands, Except Value at Percentages) Valuation 9/30/16 Balance at Allowance at Fair Value at Valuation Unobservable (Weighted Asset 9/30/16 9/30/16 9/30/16 Technique Inputs Average) Impaired loans: Residential mortgage loans - first liens $ 0 $ 0 $ 0 Sales comparison Discount to appraised value 0 % Commercial: Commercial loans secured by real estate 2,794 528 2,266 Sales comparison Discount to appraised value 7 % Commercial and industrial 321 106 215 Sales comparison Discount to appraised value 35 % Commercial construction and land 0 0 0 Sales comparison Discount to appraised value 0 % Loans secured by farmland 506 51 455 Sales comparison Discount to appraised value 55 % Multi-family (5 or more) residential 0 0 0 Sales comparison Discount to appraised value 0 % Total impaired loans $ 3,621 $ 685 $ 2,936 Foreclosed assets held for sale - real estate: Residential (1-4 family) $ 1,195 $ 0 $ 1,195 Sales comparison Discount to appraised value 39 % Land 696 0 696 Sales comparison Discount to appraised value 29 % Commercial real estate 430 0 430 Sales comparison Discount to appraised value 50 % Total foreclosed assets held for sale $ 2,321 $ 0 $ 2,321 CITIZENS & NORTHERN CORPORATION – FORM 10-Q (In Thousands, Except Value at Percentages) Valuation 12/31/15 Balance at Allowance at Fair Value at Valuation Unobservable (Weighted Asset 12/31/15 12/31/15 12/31/15 Technique Inputs Average) Impaired loans: Residential mortgage loans - first liens $ 42 $ 1 $ 41 Sales comparison Discount to appraised value 31 % Commercial: Commercial loans secured by real estate 317 97 220 Sales comparison Discount to appraised value 46 % Commercial and industrial 75 75 0 Sales comparison Discount to appraised value 31 % Commercial construction and land 0 0 0 Sales comparison Discount to appraised value 0 % Loans secured by farmland 512 52 460 Sales comparison Discount to appraised value 49 % Multi-family (5 or more) residential 987 595 392 Sales comparison Discount to appraised value 41 % Total impaired loans $ 1,933 $ 820 $ 1,113 Foreclosed assets held for sale - real estate: Residential (1-4 family) $ 556 $ 0 $ 556 Sales comparison Discount to appraised value 32 % Land 704 0 704 Sales comparison Discount to appraised value 29 % Total foreclosed assets held for sale $ 1,260 $ 0 $ 1,260 Certain of the Corporation’s financial instruments are not measured at fair value in the consolidated financial statements. 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. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Certain financial instruments and all nonfinancial instruments are excluded from disclosure requirements. Therefore, the aggregate fair value amounts presented may not represent the underlying fair value of the Corporation. The Corporation used the following methods and assumptions in estimating fair value disclosures for financial instruments: CASH AND CASH EQUIVALENTS - CERTIFICATES OF DEPOSIT - SECURITIES - LOANS HELD FOR SALE - LOANS - SERVICING RIGHTS - CITIZENS & NORTHERN CORPORATION – FORM 10-Q DEPOSITS - BORROWED FUNDS - ACCRUED INTEREST - OFF-BALANCE SHEET COMMITMENTS - The estimated fair values, and related carrying amounts, of the Corporation’s financial instruments are as follows: (In Thousands) Valuation Sept. 30, 2016 December 31, 2015 Method(s) Carrying Fair Carrying Fair Used Amount Value Amount Value Financial assets: Cash and cash equivalents Level 1 $ 30,102 $ 30,102 $ 33,313 $ 33,313 Certificates of deposit Level 2 3,968 3,982 2,748 2,752 Available-for-sale securities See Above 409,800 409,800 420,290 420,290 Restricted equity securities (included in Other Assets) Level 2 3,360 3,360 4,657 4,657 Loans held for sale Level 2 621 621 280 280 Loans, net Level 3 733,917 737,353 696,991 685,552 Accrued interest receivable Level 2 3,871 3,871 3,768 3,768 Servicing rights Level 3 1,208 1,208 1,296 1,296 Financial liabilities: Deposits with no stated maturity Level 2 769,734 769,734 713,931 713,931 Time deposits Level 2 222,146 222,881 221,684 221,891 Short-term borrowings Level 2 14,590 14,497 53,496 53,398 Long-term borrowings Level 2 38,538 39,807 38,767 40,166 Accrued interest payable Level 2 79 79 70 70

Cash flows from such investments are dependent upon the performance of the underlying mortgage loans and are generally influenced by the level of interest rates. In the table above, mortgage-backed securities and collateralized mortgage obligations are shown in one period. Investment securities carried at $221,427,000 at September 30, 2016 and $228,616,000 at December 31, 2015 were pledged as collateral for public deposits, trusts and certain other deposits as provided by law. See Note 8 for information concerning securities pledged to secure borrowing arrangements. Management evaluates securities for other-than-temporary impairment (OTTI) at least on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) whether the Corporation intends to sell the security or more likely than not will be required to sell the security before its anticipated recovery. A summary of information management considered in evaluating debt and equity securities for OTTI at September 30, 2016 is provided below. Debt Securities At September 30, 2016, management performed an assessment for possible OTTI of the Corporation’s debt securities on an issue-by-issue basis, relying on information obtained from various sources, including publicly available financial data, ratings by external agencies, brokers and other sources. The extent of individual analysis applied to each security depended on the size of the Corporation’s investment, as well as management’s perception of the credit risk associated with each security. Based on the results of the assessment, management believes impairment of debt securities at September 30, 2016 to be temporary. Equity Securities The Corporation’s marketable equity securities at September 30, 2016 and December 31, 2015 consisted exclusively of stocks of banking companies. At September 30, 2016, the Corporation held no stocks with an unrealized loss. The Corporation realized gains from sales of bank stocks totaling $560,000 in the three-month period ended September 30, 2016 and $837,000 during the first nine months of 2016. There were no realized gains or losses on bank stocks in the three-month period ended September 30, 2015, while realized gains from sales of bank stocks totaled $476,000 in the nine-month period ended September 30, 2015. CITIZENS & NORTHERN CORPORATION – FORM 10-Q C&N Bank is a member of the Federal Home Loan Bank of Pittsburgh (FHLB-Pittsburgh), which is one of 11 regional Federal Home Loan Banks. As a member, C&N Bank is required to purchase and maintain stock in FHLB-Pittsburgh. There is no active market for FHLB-Pittsburgh stock, and it must ordinarily be redeemed by FHLB-Pittsburgh in order to be liquidated. C&N Bank’s investment in FHLB-Pittsburgh stock, included in Other Assets in the consolidated balance sheet, was $3,230,000 at September 30, 2016 and $4,527,000 at December 31, 2015. The Corporation evaluated its holding of FHLB-Pittsburgh stock for impairment and deemed the stock to not be impaired at September 30, 2016 and December 31, 2015. In making this determination, management concluded that recovery of total outstanding par value, which equals the carrying value, is expected. The decision was based on review of financial information that FHLB-Pittsburgh has made publicly available.

Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	7. LOANS The loans receivable portfolio is segmented into residential mortgage, commercial and consumer loans. Loans outstanding at September 30, 2016 and December 31, 2015 are summarized by segment, and by classes within each segment, as follows: Summary of Loans by Type (In Thousands) Sept. 30, Dec. 31, 2016 2015 Residential mortgage: Residential mortgage loans - first liens $ 325,533 $ 304,783 Residential mortgage loans - junior liens 22,794 21,146 Home equity lines of credit 38,623 39,040 1-4 Family residential construction 23,310 21,121 Total residential mortgage 410,260 386,090 Commercial: Commercial loans secured by real estate 149,938 154,779 Commercial and industrial 86,969 75,196 Political subdivisions 38,653 40,007 Commercial construction and land 12,809 5,122 Loans secured by farmland 6,900 7,019 Multi-family (5 or more) residential 8,133 9,188 Agricultural loans 4,313 4,671 Other commercial loans 11,557 12,152 Total commercial 319,272 308,134 Consumer 12,806 10,656 Total 742,338 704,880 Less: allowance for loan losses (8,421 ) (7,889 ) Loans, net $ 733,917 $ 696,991 The Corporation grants loans to individuals as well as commercial and tax-exempt entities. Commercial, residential and personal loans are made to customers geographically concentrated in the Pennsylvania and New York counties that comprise the market serviced by Citizens & Northern Bank. Although the Corporation has a diversified loan portfolio, a significant portion of its debtors’ ability to honor their contracts is dependent on the local economic conditions within the region. There is no concentration of loans to borrowers engaged in similar businesses or activities that exceed 10% of total loans at either September 30, 2016 or December 31, 2015. The Corporation maintains an allowance for loan losses that represents management’s estimate of the losses inherent in the loan portfolio as of the balance sheet date and recorded as a reduction of the investment in loans. The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on the Corporation’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. In the process of evaluating the loan portfolio, management also considers the Corporation’s exposure to losses from unfunded loan commitments. As of September 30, 2016 and December 31, 2015, management determined that no allowance for credit losses related to unfunded loan commitments was required. CITIZENS & NORTHERN CORPORATION – FORM 10-Q Transactions within the allowance for loan losses, summarized by segment and class, for the three-month and nine-month periods ended September 30, 2016 and 2015 were as follows: Three Months Ended September 30, 2016 June 30, Sept. 30, (In Thousands) 2016 Balance Charge-offs Recoveries Provision (Credit) 2016 Balance Allowance for Loan Losses: Residential mortgage: Residential mortgage loans - first liens $ 2,830 $ (31 ) $ 2 $ 155 $ 2,956 Residential mortgage loans - junior liens 239 0 0 9 248 Home equity lines of credit 359 0 0 0 359 1-4 Family residential construction 222 0 0 14 236 Total residential mortgage 3,650 (31 ) 2 178 3,799 Commercial: Commercial loans secured by real estate 2,083 0 0 304 2,387 Commercial and industrial 1,038 (2 ) 1 1 1,038 Commercial construction and land 105 0 0 41 146 Loans secured by farmland 103 0 0 3 106 Multi-family (5 or more) residential 248 0 0 (5 ) 243 Agricultural loans 47 0 0 (4 ) 43 Other commercial loans 119 0 0 (3 ) 116 Total commercial 3,743 (2 ) 1 337 4,079 Consumer 138 (28 ) 12 23 145 Unallocated 398 0 0 0 398 Total Allowance for Loan Losses $ 7,929 $ (61 ) $ 15 $ 538 $ 8,421 Three Months Ended September 30, 2015 June 30, Sept. 30, (In Thousands) 2015 Balance Charge-offs Recoveries Provision (Credit) 2015 Balance Allowance for Loan Losses: Residential mortgage: Residential mortgage loans - first liens $ 2,775 $ (12 ) $ 0 $ (112 ) $ 2,651 Residential mortgage loans - junior liens 210 (42 ) 0 45 213 Home equity lines of credit 344 0 0 (5 ) 339 1-4 Family residential construction 257 0 0 55 312 Total residential mortgage 3,586 (54 ) 0 (17 ) 3,515 Commercial: Commercial loans secured by real estate 1,692 0 0 39 1,731 Commercial and industrial 800 0 1 127 928 Commercial construction and land 296 (115 ) 0 (74 ) 107 Loans secured by farmland 155 0 0 (45 ) 110 Multi-family (5 or more) residential 80 0 0 231 311 Agricultural loans 40 0 0 3 43 Other commercial loans 120 0 0 1 121 Total commercial 3,183 (115 ) 1 282 3,351 Consumer 135 (28 ) 10 6 123 Unallocated 396 0 0 31 427 Total Allowance for Loan Losses $ 7,300 $ (197 ) $ 11 $ 302 $ 7,416 CITIZENS & NORTHERN CORPORATION – FORM 10-Q Nine Months Ended September 30, 2016 Dec. 31, Sept. 30, (In Thousands) 2015 Balance Charge-offs Recoveries Provision (Credit) 2016 Balance Allowance for Loan Losses: Residential mortgage: Residential mortgage loans - first liens $ 2,645 $ (73 ) $ 2 $ 382 $ 2,956 Residential mortgage loans - junior liens 219 0 0 29 248 Home equity lines of credit 347 0 0 12 359 1-4 Family residential construction 207 0 0 29 236 Total residential mortgage 3,418 (73 ) 2 452 3,799 Commercial: Commercial loans secured by real estate 1,939 0 2 446 2,387 Commercial and industrial 981 (2 ) 2 57 1,038 Commercial construction and land 58 0 0 88 146 Loans secured by farmland 106 0 0 0 106 Multi-family (5 or more) residential 675 (595 ) 0 163 243 Agricultural loans 45 0 0 (2 ) 43 Other commercial loans 118 0 0 (2 ) 116 Total commercial 3,922 (597 ) 4 750 4,079 Consumer 122 (67 ) 39 51 145 Unallocated 427 0 0 (29 ) 398 Total Allowance for Loan Losses $ 7,889 $ (737 ) $ 45 $ 1,224 $ 8,421 Nine Months Ended September 30, 2015 Dec. 31, Sept. 30, (In Thousands) 2014 Balance Charge-offs Recoveries Provision (Credit) 2015 Balance Allowance for Loan Losses: Residential mortgage: Residential mortgage loans - first liens $ 2,941 $ (149 ) $ 1 $ (142 ) $ 2,651 Residential mortgage loans - junior liens 176 (42 ) 0 79 213 Home equity lines of credit 322 0 0 17 339 1-4 Family residential construction 214 0 0 98 312 Total residential mortgage 3,653 (191 ) 1 52 3,515 Commercial: Commercial loans secured by real estate 1,758 (115 ) 0 88 1,731 Commercial and industrial 688 (10 ) 5 245 928 Commercial construction and land 283 (115 ) 0 (61 ) 107 Loans secured by farmland 165 0 0 (55 ) 110 Multi-family (5 or more) residential 87 0 0 224 311 Agricultural loans 31 0 0 12 43 Other commercial loans 131 0 0 (10 ) 121 Total commercial 3,143 (240 ) 5 443 3,351 Consumer 145 (65 ) 44 (1 ) 123 Unallocated 395 0 0 32 427 Total Allowance for Loan Losses $ 7,336 $ (496 ) $ 50 $ 526 $ 7,416 CITIZENS & NORTHERN CORPORATION – FORM 10-Q In the evaluation of the loan portfolio, management determines two major components for the allowance for loan losses – (1) a specific component based on an assessment of certain larger relationships, mainly commercial purpose loans, on a loan-by-loan basis; and (2) a general component for the remainder of the portfolio based on a collective evaluation of pools of loans with similar risk characteristics. The general component is assigned to each pool of loans based on both historical net charge-off experience, and an evaluation of certain qualitative factors. 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 above methodologies for estimating specific and general losses in the portfolio. In determining the larger loan relationships for detailed assessment under the specific allowance component, the Corporation uses an internal risk rating system. Under the risk rating system, the Corporation classifies problem or potential problem loans as “Special Mention,” “Substandard,” or “Doubtful” on the basis of currently existing facts, conditions and values. Substandard loans include those characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Loans that do not currently expose the Corporation to sufficient risk to warrant classification as Substandard or Doubtful, but possess weaknesses that deserve management’s close attention, are deemed to be Special Mention. Risk ratings are updated any time that conditions or the situation warrants. Loans not classified are included in the “Pass” column in the table below. The following tables summarize the aggregate credit quality classification of outstanding loans by risk rating as of September 30, 2016 and December 31, 2015: September 30, 2016 (In Thousands) Special Pass Mention Substandard Doubtful Total Residential Mortgage: Residential mortgage loans - first liens $ 315,849 $ 331 $ 9,292 $ 61 $ 325,533 Residential mortgage loans - junior liens 22,376 145 273 0 22,794 Home equity lines of credit 37,925 124 574 0 38,623 1-4 Family residential construction 23,310 0 0 0 23,310 Total residential mortgage 399,460 600 10,139 61 410,260 Commercial: Commercial loans secured by real estate 133,140 3,087 13,711 0 149,938 Commercial and Industrial 82,076 4,196 686 11 86,969 Political subdivisions 38,653 0 0 0 38,653 Commercial construction and land 12,707 66 36 0 12,809 Loans secured by farmland 5,243 168 1,472 17 6,900 Multi-family (5 or more) residential 7,505 0 628 0 8,133 Agricultural loans 3,503 0 810 0 4,313 Other commercial loans 11,482 0 75 0 11,557 Total commercial 294,309 7,517 17,418 28 319,272 Consumer 12,651 0 155 0 12,806 Totals $ 706,420 $ 8,117 $ 27,712 $ 89 $ 742,338 CITIZENS & NORTHERN CORPORATION – FORM 10-Q December 31, 2015 (In Thousands) Special Pass Mention Substandard Doubtful Total Residential Mortgage: Residential mortgage loans - first liens $ 295,302 $ 407 $ 9,007 $ 67 $ 304,783 Residential mortgage loans - junior liens 20,558 185 403 0 21,146 Home equity lines of credit 38,071 543 426 0 39,040 1-4 Family residential construction 21,104 17 0 0 21,121 Total residential mortgage 375,035 1,152 9,836 67 386,090 Commercial: Commercial loans secured by real estate 140,381 5,862 8,536 0 154,779 Commercial and Industrial 71,225 2,106 1,737 128 75,196 Political subdivisions 40,007 0 0 0 40,007 Commercial construction and land 4,957 60 105 0 5,122 Loans secured by farmland 5,084 483 1,432 20 7,019 Multi-family (5 or more) residential 7,943 0 1,245 0 9,188 Agricultural loans 4,655 0 16 0 4,671 Other commercial loans 12,073 0 79 0 12,152 Total commercial 286,325 8,511 13,150 148 308,134 Consumer 10,490 21 145 0 10,656 Totals $ 671,850 $ 9,684 $ 23,131 $ 215 $ 704,880 The general component of the allowance for loan losses covers pools of loans including commercial loans not considered individually impaired, as well as smaller balance homogeneous classes of loans, such as residential real estate, home equity lines of credit and other consumer loans. Accordingly, the Corporation generally does not separately identify individual consumer and residential loans for impairment disclosures, unless such loans are subject to a restructuring agreement. The pools of loans are evaluated for loss exposure based upon three-year average historical net charge-off rates for each loan class, adjusted for qualitative factors. Qualitative risk factors (described in the following paragraph) are evaluated for the impact on each of the three segments (residential mortgage, commercial and consumer) within the loan portfolio. Each qualitative factor is assigned a value to reflect improving, stable or declining conditions based on management’s judgment using relevant information available at the time of the evaluation. The adjustment for qualitative factors is applied as an increase or decrease to the three-year average net charge-off rate to each loan class within each segment. The qualitative factors used in the general component calculations are designed to address credit risk characteristics associated with each segment. The Corporation’s credit risk associated with all of the segments is significantly impacted by these factors, which include economic conditions within its market area, the Corporation’s lending policies, changes or trends in the portfolio, risk profile, competition, regulatory requirements and other factors. Further, the residential mortgage segment is significantly affected by the values of residential real estate that provide collateral for the loans. The majority of the Corporation’s commercial segment loans (approximately 56% at September 30, 2016) is secured by real estate, and accordingly, the Corporation’s risk for the commercial segment is significantly affected by commercial real estate values. The consumer segment includes a wide mix of loans for different purposes, primarily secured loans, including loans secured by motor vehicles, manufactured housing and other types of collateral. Loans are classified as impaired, when, based on current information and events, it is probable that the Corporation 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 payment 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 shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial loans, by the fair value of the collateral (if the loan is collateral dependent), by future cash flows discounted at the loan’s effective rate or by the loan’s observable market price. CITIZENS & NORTHERN CORPORATION – FORM 10-Q The scope of loans evaluated individually for impairment include all loan relationships greater than $200,000 for which there is at least one extension of credit graded Special Mention, Substandard or Doubtful. Also, all loans classified as troubled debt restructurings (discussed in more detail below) and all loan relationships less than $200,000 in the aggregate, but with an estimated loss of $100,000 or more, are individually evaluated for impairment. Loans that are individually evaluated for impairment, but which are not determined to be impaired, are combined with all remaining loans that are not reviewed on a specific basis, and such loans are included within larger pools of loans based on similar risk and loss characteristics for purposes of determining the general component of the allowance.

Any unpaid interest previously accrued on those loans is reversed from income. Interest income is not recognized on specific impaired loans unless the likelihood of further loss is remote. Interest payments received on loans for which the risk of further loss is greater than remote are applied as a reduction of the loan principal balance. Interest income on other nonaccrual loans, including impaired loans, is recognized only to the extent of interest payments received. 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. Also, the amortization of deferred loan fees is discontinued when a loan is placed on nonaccrual status.

Also, the FHLB-Pittsburgh loan facilities require the Corporation to invest in established amounts of FHLB-Pittsburgh stock. The carrying values of the Corporation’s holdings of FHLB-Pittsburgh stock (included in Other Assets) were $3,230,000 at September 30, 2016 and $4,527,000 at December 31, 2015. At September 30, 2016, short-term borrowings from the FHLB-Pittsburgh include 3 advances of approximately $2,090,000 each, maturing monthly throughout the remainder of the year ending December 31, 2016, with a weighted average interest rate of 1.03% and rates ranging from 1.006% to 1.052%. In the first nine months of 2016, the Corporation repaid nine advances of approximately $2,090,000 each, with a weighted average rate of 0.80%. The Corporation engages in repurchase agreements with certain commercial customers. These agreements provide that the Corporation sells specified investment securities to the customers on an overnight basis and repurchases them on the following business day. The weighted average interest rate paid by the Corporation on customer repurchase agreements was 0.10% at September 30, 2016 and December 31, 2015. The carrying value of the underlying securities was $16,472,000 at September 30, 2016 and $12,613,000 at December 31, 2015. Long-term borrowings are as follows: (In Thousands) Sept. 30, Dec. 31, 2016 2015 FHLB-Pittsburgh borrowings $ 11,538 $ 11,767 Repurchase agreement 27,000 27,000 Total long-term borrowings $ 38,538 $ 38,767 CITIZENS & NORTHERN CORPORATION – FORM 10-Q Long-term borrowings from FHLB-Pittsburgh are as follows: (In Thousands) Sept. 30, Dec. 31, 2016 2015 Loan maturing in 2016 with a rate of 6.86% $ 18 $ 57 Loan maturing in 2017 with a rate of 6.83% 6 10 Loan maturing in 2017 with a rate of 3.81% 10,000 10,000 Loan maturing in 2020 with a rate of 4.79% 691 821 Loan maturing in 2025 with a rate of 4.91% 823 879 Total long-term FHLB-Pittsburgh borrowings $ 11,538 $ 11,767 The repurchase agreement included in long-term borrowings has an interest rate of 3.595% and an effective maturity date in December 2017. The “Repurchase Date,” as defined in the Master Repurchase Agreement between the Corporation and the broker-dealer, occurs quarterly on or about the 20 th Securities sold under repurchase agreements were delivered to the broker-dealer who is the counter-party to the transactions. The broker-dealer may have sold, loaned or otherwise disposed of such securities to other parties in the normal course of their operations, and has agreed to resell to the Corporation substantially identical securities at the maturities of the agreements. The Master Repurchase Agreement provides that the Agreement constitutes a “netting contract,” as defined; however, the Corporation and the broker-dealer have no other obligations to one another and accordingly, no netting has occurred. The carrying value of the underlying securities was $34,130,000 at September 30, 2016 and $33,780,000 at December 31, 2015, detailed in the following table: (In Thousands) Sept. 30, Dec. 31, 2016 2015 Mortgage-backed securities issued or guaranteed by U.S. Government agencies or sponsored agencies: Residential pass-through securities $ 19,444 $ 15,772 Residential collateralized mortgage obligations 14,686 18,008 Total $ 34,130 $ 33,780 Two of the more significant risks associated with the repurchase agreement with the broker-dealer are as follows: ● The borrowings are putable at quarterly intervals by the issuer. Accordingly, if interest rates were to rise to a sufficient level, the issuer would be expected to require the Corporation to pay off the borrowing. In this circumstance, the Corporation would be required to obtain a new borrowing at a higher interest rate than the existing repurchase agreement or utilize cash from other sources to pay off the borrowing. If sales of available-for-sale securities were used to generate cash to pay off the borrowing, the value of such securities would be expected to have fallen, which could result in the Corporation recognizing a loss. ● As principal pay-downs of mortgage backed securities and CMOs occur, the Corporation must have available, unencumbered assets or purchase a sufficient amount of assets with credit quality suitable to the broker-dealer to replace the amounts being paid off. Since pre-payments of mortgages typically increase as interest rates fall, the Corporation may be required to purchase additional assets at times when market rates are lower than the rates paid on the borrowing. The Corporation manages these risks by maintaining sufficient available assets of acceptable credit quality, as well as maintaining other borrowing facilities, to meet ongoing collateral maintenance requirements or pay off the borrowing if required. In particular, the Corporation had unused borrowing capacity available from the FHLB-Pittsburgh of $315,685,000 at September 30, 2016.

Pension and Other Postretirement Benefits Disclosure [Text Block]	9. DEFINED BENEFIT PLANS The Corporation sponsors a defined benefit health care plan that provides postretirement medical benefits and life insurance to employees who meet certain age and length of service requirements. Full-time employees no longer accrue service time toward the Corporation-subsidized portion of the medical benefits. This plan contains a cost-sharing feature, which causes participants to pay for all future increases in costs related to benefit coverage. Accordingly, actuarial assumptions related to health care cost trend rates do not significantly affect the liability balance at September 30, 2016 and December 31, 2015, and are not expected to significantly affect the Corporation's future expenses. The Corporation uses a December 31 measurement date for the postretirement plan. In an acquisition in 2007, the Corporation assumed the Citizens Trust Company Retirement Plan, a defined benefit pension plan.

STOCK-BASED COMPENSATION PLANS The Corporation has a Stock Incentive Plan for a selected group of officers and an Independent Directors Stock Incentive Plan. In the three-month periods ended March 31, 2016 and 2015, the Corporation issued restricted stock under each of the Plans. In the first quarter 2016, the Corporation awarded a total of 34,199 shares of restricted stock under the Stock Incentive and Independent Directors Stock Incentive Plans. Restricted stock awards in the first quarter 2016 included the following: (1) a total of 17,289 shares to employees, vesting over a three-year term, with vesting contingent upon the Corporation meeting an annual return on average equity (“ROAE”) performance ratio, as defined; (2) a total of 10,304 shares to employees, vesting over a three-year term, with vesting dependent on satisfactory performance; and (3) a total of 6,606 shares under the Independent Directors Incentive Plan, vesting over a term of one year.

The effective tax rates for the Corporation are as follows: 3 Months Ended 9 Months Ended (In thousands) September 30, September 30, 2016 2015 2016 2015 Income before income tax provision $ 5,538 $ 5,629 $ 15,378 $ 16,482 Income tax provision 1,451 1,395 3,847 4,076 Effective tax rate 26.20 % 24.78 % 25.02 % 24.73 % The effective tax rate for each period presented differs from the statutory rate of 35% principally because of the effects of tax-exempt interest income. The Corporation has investments in three limited partnerships that manage affordable housing projects that have qualified for the federal low-income housing tax credit. The Corporation’s expected return from these investments is based on the receipt of tax credits and tax benefits from deductions of operating losses. The Corporation uses the effective yield method to account for these investments, with the benefits recognized as a reduction of the provision for income taxes. For two of the three limited partnership investments, the tax credits have been received in full in prior years, and the Corporation has fully realized the benefits of the credits and amortized its initial investments in the partnerships. The most recent affordable housing project was completed in 2013, and the Corporation received tax credits in 2013, 2014 and 2015 and expects to continue to receive tax credits annually through 2022. The carrying amount of the Corporation’s investment is $737,000 at September 30, 2016 and $812,000 at December 31, 2015 (included in Other Assets in the consolidated balance sheets). For the year ending December 31, 2016, the estimated amount of tax credits and other tax benefits to be received is $158,000 and the estimated amount to be recognized as a reduction of the provision for income taxes is $76,000. For the year ended December 31, 2015, tax credits and other tax benefits totaled $158,000 and the amount recognized as a reduction of the provision for income taxes for 2015 was $80,000. The total reduction in the provision for income taxes resulting from this investment is $19,000 in the third quarter 2016, and $57,000 for the nine months ended September 30, 2016, and $22,000 in the third quarter 2015, and $62,000 for the nine months ended September 30, 2015. The Corporation has no unrecognized tax benefits, nor pending examination issues related to tax positions taken in preparation of its income tax returns. With limited exceptions, the Corporation is no longer subject to examination by the Internal Revenue Service for years prior to 2013.

Accounting Changes and Error Corrections [Text Block]	13. RECENT ACCOUNTING PRONOUNCEMENTS The FASB issues Accounting Standards Updates (ASUs) to the FASB ASC. This section provides a summary description of recent ASUs that have significant implications (elected or required) within the consolidated financial statements, or that management expects may have a significant impact on financial statements issued in the near future. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which provides a principles-based framework for revenue recognition that supersedes virtually all previously issued revenue recognition guidance under U.S. GAAP. Additionally, the ASU requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. The core principle of the five-step revenue recognition framework 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. In April 2016, the FASB issued ASU 2016-10, which provides clarifying information related to identifying performance obligations and licensing. In May 2016, the FASB issued ASU 2016-12, which provides clarifying guidance in a few narrow areas and adds some practical expedients to the guidance. In August 2015 the FASB issued ASU 2015-14, which deferred the effective date of the revenue recognition standard by a year, making it applicable for the Corporation in the first quarter 2018 and for the annual period ending December 31, 2018. The amendments should be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the amendments recognized at the date of initial application. The Corporation is in the process of evaluating the potential impact of adopting the amendments, including determining which transition method to apply. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities. This makes significant changes in U.S. GAAP related to certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The changes provided for in this Update that are applicable to the Corporation are as follows: (1) require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; however, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer; (2) for equity investments without readily determinable fair values, require a qualitative assessment to identify impairment, and if a qualitative assessment indicates that impairment exists, requiring an entity to measure the investment at fair value; (3) eliminate the requirement for public 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; (4) require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (5) require 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 (at September 30, 2016 and December 31, 2015, the Corporation has no liabilities for which the fair value measurement option has been elected); (6) require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements; and (7) clarify 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. The amendments in this Update will become effective for the Corporation for annual and interim periods beginning in the first quarter 2018. With limited exceptions, early adoption of the amendments in this Update is not permitted. Amendments are to be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values should be applied prospectively. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. Specifically, a lessee should recognize on the balance sheet a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee would be permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities. Topic 842 would not significantly change the recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee from current U.S. GAAP; however, the principal change from current GAAP is that lease assets and liabilities arising from operating leases would be recognized on the balance sheet. Topic 842 provides several other changes or clarifications to existing GAAP, and will require qualitative disclosures, along with quantitative disclosures, so that financial statement users can understand more about the nature of an entity’s leasing activities. In transition, Topic 842 provides that lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach, including optional practical expedients. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees will be required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. Topic 842 will become effective for the Corporation for annual and interim periods beginning in the first quarter 2019. In March 2016, the FASB issued ASU No. 2016-07, Investments – Equity Method and Joint Ventures. This ASU eliminates the requirement that when an investment qualifies for the equity method as a result of an increase in the level of ownership interest or influence, an investor must adjust the investment, results of operations and retained earnings retroactively as if the equity method had been in effect during all previous periods the investment had been held. The ASU requires the equity method investor to add the cost of acquiring an additional interest in the investee to the basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for the equity method. The ASU further requires that an entity that has an available-for-sale equity security that becomes qualified for the equity method recognize through earnings the unrealized gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this Update are effective for the Corporation for annual and interim periods beginning in the first quarter 2017, with earlier application permitted. The amendments should be applied prospectively upon their effective date. In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation. This ASU changes several aspects of accounting for share-based payment transactions, and includes some changes that apply only to nonpublic companies. This Update includes amendments that currently apply, or may apply in the future, to the Corporation related to the following: (1) accounting for the difference between the deduction for tax purposes and the amount of compensation cost recognized for financial reporting purposes; (2) classification of excess tax benefits on the statement of cash flows; (3) accounting for forfeitures; (4) accounting for awards partially settled in cash in excess of the employer’s minimum statutory tax withholding requirements; and (5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. The amendments in this Update are effective for the Corporation for annual and interim periods beginning in the first quarter 2017, with earlier adoption permitted. The ASU provides separate transition provisions for each of the amendments. The Corporation is in the process of evaluating the potential impact of adopting the amendments. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326). This ASU will result in significant changes in the Corporation’s accounting for credit losses related to loans receivable and investment securities. A summary of significant provisions of this ASU is as follows: ● The ASU requires that a financial asset (or a group of financial assets) measured at amortized cost basis be presented, net of a valuation allowance for credit losses, at an amount expected to be collected on the financial asset(s), and that the income statement include the measurement of credit losses for newly recognized financial assets as well as changes in expected losses on previously recognized financial assets. The provisions of this ASU require measurement of expected credit losses based on relevant information including past events, historical experience, current conditions, and reasonable and supportive forecasts that affect the collectability of the asset. The provisions of this ASU differ from current U.S. GAAP in that current U.S. GAAP generally delays recognition of the full amount of credit losses until the loss is probable of occurring. ● The amendments in the Update retain many of the disclosure requirements related to credit quality in current U.S. GAAP, updated to reflect the change from an incurred loss methodology to an expected credit loss methodology. In addition, the Update requires that disclosure of credit quality indicators in relation to the amortized cost of financing receivables, a current requirement, be further disaggregated by year of origination. ● This ASU requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down, and limits the amount of the allowance for credit losses to the amount by which the fair value is below amortized cost. For purchased available-for-sale securities with a more-than-insignificant amount of credit deterioration since origination, the ASU requires an allowance be determined in a manner similar to other available-for-sale debt securities; however, the initial allowance would be added to the purchase price, with only subsequent changes in the allowance recorded in credit loss expense, and interest income recognized at the effective rate excluding the discount embedded in the purchase price related to estimated credit losses at acquisition. ● This ASU will be effective for the Corporation for interim and annual periods beginning in the first quarter of 2020. Earlier adoption is permitted beginning in the first quarter of 2019. The entity will record the effect of implementing this ASU through a cumulative-effect adjustment through retained earnings as of the beginning of the reporting period in which Topic 326 is effective. The Corporation is in the early stages of evaluating the potential impact of adopting this amendment. In June 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) –Classification of Certain Cash Receipts and Cash Payments. This Update provides clarification regarding eight specific cash flow issues with the objective of reducing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. For the Corporation, the amendments in this Update are effective beginning in the first quarter 2018. The amendments in this Update should be applied using a retroactive transition method to each period presented. The Corporation anticipates there will be no adjustments to the Consolidated Statements of Cash Flows, as previously reported, as a result of the clarifications provided in the Update.
