Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Note 1: Basis of Presentation The accompanying unaudited consolidated financial statements of Pathfinder Bancorp, Inc., (the “Company”), Pathfinder Bank (the “Bank”) and its other wholly owned subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions for Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a complete presentation of consolidated financial condition, results of operations and cash flows in conformity with generally accepted accounting principles. In the opinion of management, all adjustments, consisting of normal recurring accruals considered necessary for a fair presentation, have been included. Certain amounts in the 2016 consolidated financial statements may have been reclassified to conform to the current period presentation. These reclassifications had no effect on net income or comprehensive income as previously reported. 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 full year ending December 31, 2017 or any other interim period. The Company's consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States and follow practices within the banking industry. Application of these principles requires management to make estimates, assumptions, and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements could reflect different estimates, assumptions, and judgments. Certain policies inherently have a greater reliance on the use of estimates, assumptions, and judgments and as such have a greater possibility of producing results that could be materially different than originally reported. Estimates, assumptions, and judgments are necessary when assets and liabilities are required to be recorded at fair value or when an asset or liability needs to be recorded contingent upon a future event. Carrying assets and liabilities at fair value inherently results in more financial statement volatility. The fair values and information used to record valuation adjustments for certain assets and liabilities are based on quoted market prices or are provided by other third-party sources, when available. When third party information is not available, valuation adjustments are estimated in good faith by management. Although the Company owns, through its subsidiary Pathfinder Risk Management Company, Inc., 51% of the membership interest in FitzGibbons Agency, LLC (“Agency”), the Company is required to consolidate 100% of the Agency within the consolidated financial statements. The 49% of which the Company does not own is accounted for separately as noncontrolling interests within the consolidated financial statements. On February 16, 2016, the Company redeemed all 13,000 shares of the Series B Preferred Stock outstanding with the payment of $13.0 million to the Small Business Lending Facility (“SBLF”). This redemption was substantially financed by the issuance on October 15, 2015 of the $10.0 million Subordinated Loan with an effective annual interest rate of 6.44%. The issuance of the Subordinated Loan has increased interest expense by approximately $644,000 per year, but prospectively reduced the future amount payable to the SBLF in preferred stock dividends. Had the preferred stock not been retired, effective April 1, 2016, the annual dividend rate for the preferred stock would have been 9.0%. Therefore, the retirement of the $13.0 million of the SBLF Preferred Series B stock has resulted in an annual reduction of dividends payable to the preferred shareholder of $1.2 million. The Company paid preferred stock dividends totaling $-0- in 2017 and $16,000 in 2016. These transactions had no effect on the regulatory capital position of the Bank.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
New Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards ASU (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) The Company has formed an Implementation Committee, whose membership includes representatives of senior management, to develop plans that will encompass: (1) internal methodology changes (2) data collection and management activities, (3) internal communication requirements, and (4) estimation of the projected impact of this ASU. The Implementation Committee is currently evaluating the impact the ASU will have on the Company's consolidated financial statements, and expects an increase in the allowance for credit losses resulting from the change to expected losses for the estimated life of the financial asset, including an allowance for debt securities. The amount of the increase in the allowance for credit losses resulting from the new guidance will be impacted by the portfolio composition and asset quality at the adoption date, as well as economic conditions and forecasts at the time of adoption. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350 In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260) . In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities . To accomplish that objective, the amendments in this ASU require the following recognition and presentation guidance for qualifying hedges: 1. For fair value hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness is presented in the same income statement line that is used to present the earnings effect of the hedged item. The timing of recognition of the change in fair value of a hedging instrument included in the assessment of hedge effectiveness is the same as under current GAAP, but the presentation of hedge results could change because current GAAP does not specify a required presentation of the change in fair value of the hedging instrument. 2. For cash flow hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness is recorded in other comprehensive income. Those amounts are reclassified to earnings in the same income statement line item that is used to present the earnings effect of the hedged item when the hedged item affects earnings. The timing of recognition of the change in fair value of a hedging instrument could change relative to current GAAP because hedge ineffectiveness no longer is recognized currently in earnings. The presentation of hedge results also could change because current GAAP does not specify a required presentation of the change in fair value of the hedging instrument in the income statement. The amendments in this ASU also include certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. Current GAAP contains specific requirements for initial and ongoing quantitative hedge effectiveness testing and strict requirements for specialized effectiveness testing methods that allow an entity to forgo quantitative hedge effectiveness assessments for qualifying relationships (for example, “shortcut” method and “critical terms match” method). The amendments change hedge effectiveness testing as follows: 1. In instances in which initial quantitative testing is required, an entity may perform subsequent assessments of hedge effectiveness qualitatively. An entity that makes this election is required to verify and document on a quarterly basis that the facts and circumstances related to the hedging relationship have not changed such that the entity can assert qualitatively that the hedging relationship was and continues to be highly effective. An entity may elect to perform qualitative assessments on a hedge-by-hedge basis. 2. For purposes of assessing whether the qualifying criteria for the critical terms match method are met for a group of forecasted transactions, an entity may assume that the hedging derivative matures at the same time as the forecasted transactions if both the derivative maturity and the forecasted transactions occur within the same 31-day period or fiscal month. 3. Entities will be able to perform the initial prospective quantitative assessment of hedge effectiveness at any time after hedge designation, but no later than the first quarterly effectiveness testing date, using data applicable as of the date of hedge inception. 4. If an entity that applies the shortcut method determines that use of that method was not or no longer is appropriate, the entity may apply a “long-haul” method for assessing hedge effectiveness as long as the hedge is highly effective and the entity documents at inception which long-haul methodology it will use. The amendments in this ASU also significantly modify disclosures required in current GAAP. Those modifications include a tabular disclosure related to the effect on the income statement of fair value and cash flow hedges and eliminate the requirement to disclose the ineffective portion of the change in fair value of hedging instruments. The amendments also require new tabular disclosures related to cumulative basis adjustments for fair value hedges. For public business entities, such as the Company, the amendments in this ASU are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early application is permitted in any interim period after issuance of the ASU. All transition requirements and elections should be applied to hedging relationships existing (that is, hedging relationships in which the hedging instrument has not expired, been sold, terminated, or exercised or the entity has not removed the designation of the hedging relationship) on the date of adoption. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption (that is, the initial application date). For cash flow hedges existing at the date of adoption, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the amendments in this ASU. The amended presentation and disclosure guidance is required only prospectively. The provisions of this ASU are complex and the application of this ASU in future periods will depend heavily upon both the levels and types of hedging activities that the Company engages in. The level and types of future hedging activities will be in turn dependent upon a number of factors, including but not limited to, prevailing economic conditions, the Company’s interest-earning asset and interest-bearing liability composition, general interest rates, industry regulations and similar considerations. Accordingly, it is not possible for management to determine the potential impact of this ASU on future accounting periods or to determine if early adoption of this ASU will have any material effect on accounting periods prior to the ASU’s mandatory implementation date. Given the currently limited use of hedging activities by the Company as of the reporting date, management of the Company does not believe that adoption of this ASU would have had any material impact on its consolidated financial statements of condition, results of operations, or cash flows as of that date.

Earnings Per Share [Abstract]
Earnings per Common Share	Note 3: Earnings per Common Share Basic earnings per share are calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Net income available to common shareholders is net income to Pathfinder Bancorp, Inc. less the total of preferred dividends declared, if any. Diluted earnings per share include the potential dilutive effect that could occur upon the assumed exercise of issued stock options using the Treasury Stock method. Anti-dilutive stock options, not included in the computation below, were -0- for the three months ended September 30, 2017 and 30,754 for the nine months ended September 30, 2017 and were 280,396 for the three months ended September 30, 2016 and 192,421 for the nine months ended September 30, 2016. Unallocated common shares held by the ESOP are not included in the weighted-average number of common shares outstanding for purposes of calculating earnings per common share until they are committed to be released to plan participants. The following table sets forth the calculation of basic and diluted earnings per share.

The Company assesses whether OTTI is present when the fair value of a debt security is less than its amortized cost basis at the statement of condition date. Under these circumstances, OTTI is considered to have occurred (1) if we intend to sell the security; (2) if it is “more likely than not” we will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not anticipated to be sufficient to recover the entire amortized cost basis. The guidance requires that credit-related OTTI is recognized in earnings while non-credit-related OTTI on securities not expected to be sold is recognized in other comprehensive income (“OCI”). Non-credit-related OTTI is based on other factors, including illiquidity and changes in the general interest rate environment. Presentation of OTTI is made in the consolidated statement of income on a gross basis, including both the portion recognized in earnings as well as the portion recorded in OCI. The gross OTTI would then be offset by the amount of non-credit-related OTTI, showing the net as the impact on earnings. Management does not believe any individual unrealized loss in the securities portfolio as of September 30, 2017 represents OTTI. With the exception of certain individually small, primarily local market, municipal bond issuances, substantially all of securities held in the portfolio are rated at or above the lowest tier of investment grade by one or more nationally recognized statistical rating organizations (NRSRO). At September 30, 2017, the investment portfolio held three corporate issuances, At September 30, 2017, 15 municipal securities, with an aggregate amortized cost of $5.1 million, and categorized as available-for-sale, have been in a loss position for twelve months or more and have an aggregate loss position of 3.35%. The majority of the securities are rated in the top two credit categories by a NRSRO, with the exception of two At September 30, 2017, nine municipal securities, with an aggregate amortized cost of $4.4 million, and categorized as held-to-maturity, have been in a loss position for less than twelve months and have an aggregate loss position of 1.33%. All of the securities are rated in the top two credit categories by a NRSRO with the exception of three individually small issuances that were unrated at issuance. Each of the municipal securities in a loss position for less than twelve months at September 30, 2017 had unrealized losses ranging from 0.02% to 3.25%. These losses are related to the securities’ relatively long duration and the current market pricing of imbedded call features within these securities and not to credit factors. Accordingly, none of these municipal securities are deemed to have any credit impairment at the reporting date. At September 30, 2017, eight municipal securities, with an aggregate amortized cost of $7.8 million, and categorized as held-to-maturity, have been in a loss position for twelve months or more and have an aggregate loss position of 2.69%. All of the securities are rated in the top two credit categories by a NRSRO. Each of the municipal securities in a loss position for twelve months or more at September 30, 2017 had unrealized losses ranging from 1.62% to 4.42%. These losses are related to the securities’ relatively long duration and the current market pricing of imbedded call features within these securities and not to credit factors. Accordingly, none of these municipal securities are deemed to have any credit impairment at the reporting date. At September 30, 2017, one corporate security, which was unrated at issuance, with an aggregate amortized cost of $4.9 million and categorized as available-for-sale, has been in a loss position for less than twelve months, and has an aggregate unrealized loss of 0.21% at September 30, 2017. One corporate security, rated above the lowest level of investment grade by a NRSRO, with an aggregate amortized cost of $1.8 million and categorized as available-for-sale, has been in a loss position for twelve months or more. The unrealized loss on this security at September 30, 2017 was 2.76% of its amortized historical cost. Neither security is deemed to have any credit impairment at the reporting date. Three corporate securities, with aggregate amortized costs of $3.1 million have been in a loss positions for less than twelve months. The securities are categorized as held-to-maturity. Two of the securities are rated at least at the lowest investment grade by an NRSRO and one of the securities was unrated at issuance. In aggregate, these securities have an unrealized loss of 4.30% at September 30, 2017, with individual losses ranging from 0.32% to 5.83%. These losses are related to the securities’ relatively long duration and not to credit factors. Accordingly, none of these corporate securities are deemed to have any credit impairment at the reporting date. One corporate security, with an amortized cost of $833,000 has been in a loss positions for twelve months or more. This security is categorized as held-to-maturity and was unrated at issuance. The unrealized loss of 0.18% at September 30, 2017 was related to the securities’ relatively long duration and not to credit factors. Accordingly, this corporate security was not deemed to have any credit impairment at the reporting date. One fixed rate, private-label asset-backed security, with an amortized cost of $1.0 million has been in a loss position for less than twelve months at September 30, 2017. This security is categorized as available-for-sale and was unrated at issuance. The security has an unrealized loss of 1.0% at September 30, 2017 and has significant collateral enhancement protecting its principal value. Management monitors the performance of all private-label securities closely and has determined that there is no credit impairment present related to this security at September 30, 2017. One fixed rate, private-label asset-backed security, with an amortized cost of $756,000 has been in a loss position for twelve months or more at September 30, 2017. This security is categorized as available-for-sale and was unrated at issuance. The security has an unrealized loss of 1.61% at September 30, 2017 and has significant collateral enhancement protecting its principal value. Management monitors the performance of all private-label securities closely and has determined that there is no credit impairment present related to this security at September 30, 2017. Five private-label mortgage-backed securities, with an aggregate amortized cost of $7.5 million have been in a loss position for less than twelve months at September 30, 2017. These securities are categorized as available-for-sale and four of the five were unrated at issuance with the fifth security being rated AAA by Standard & Poors. The securities have an unrealized aggregate loss of 2.00% with individual security losses ranging from 0.80% to 4.28% at September 30, 2017. Each security has significant collateral enhancement protecting its principal value. Management monitors the performance of all private-label securities closely and has determined that there is no credit impairment present related to these securities at the reporting date. Two private-label mortgage-backed securities, with an aggregate amortized cost of $2.2 million have been in a loss position for twelve months or more at September 30, 2017. These securities are categorized as available-for-sale and were unrated at issuance. The securities have an unrealized aggregate loss of 0.58% with individual security losses ranging from 0.19% to 0.85% at September 30, 2017. Each security has significant collateral enhancement protecting its principal value. Management monitors the performance of all private-label securities closely and has determined that there is no credit impairment present related to these securities at the reporting date. One private-label mortgage-backed security, with an amortized cost of $1.2 million has been in a loss position for twelve months or more at September 30, 2017. This security is categorized as held-to-maturity and was unrated at issuance. The security has an unrealized loss of 1.01% at September 30, 2017. Each security has significant collateral enhancement protecting its principal value. Management monitors the performance of all private-label securities closely and has determined that there is no credit impairment present related to these securities at the reporting date. All other securities in an unrealized loss position at September 30, 2017 are securities issued by either the U.S. Government or its sponsored entities. The securities include mortgage-backed issuances, collateralized mortgage obligations and agency debentures issued by GNMA, FNMA, FHLMC, FHLB and FFCB. These entities are currently rated Aaa by Moody’s Investor Services and AA+ by Standard and Poors. GNMA securities carry explicit guarantees by the U.S. Government as to timely repayment of principal and securities issued by the other agencies listed above are implicitly guaranteed by the U.S. Government. The unrealized losses reflected are primarily attributable to changes in interest rates since the securities were acquired. The company does not intend to sell these securities, nor is it more likely than not, that the company will be required to sell these securities prior to recovery of the amortized cost. As such, management does not believe any individual unrealized loss as of September 30, 2017 represents OTTI. Gross realized gains (losses) on sales of securities for the indicated periods are detailed below: For the three months For the nine months ended September 30, ended September 30, (In thousands) 2017 2016 2017 2016 Realized gains on investments $ 165 $ 4 $ 313 $ 233 Realized gains on hedging activity - - 250 - Realized losses on investments (57 ) - (249 ) (17 ) $ 108 $ 4 $ 314 $ 216 As of September 30, 2017 and December 31, 2016, securities with a fair value of $111.8 million and $96.4 million, respectively, were pledged to collateralize certain municipal deposit relationships. As of the same dates, securities with a fair value of $20.9 million and $12.9 million were pledged against certain borrowing arrangements. Management has reviewed its loan and mortgage-backed securities portfolios and determined that, to the best of its knowledge, little exposure exists to sub-prime or other high-risk residential mortgages. With limited exceptions in the Company’s investment portfolio involving the most senior tranches of securitized bonds, the Company is not in the practice of investing in, or originating, these types of investments or loans.

Compensation And Retirement Disclosure [Abstract]
Pension and Postretirement Benefits	Note 5: Pension and Postretirement Benefits The Company has a noncontributory defined benefit pension plan covering substantially all employees. The plan provides defined benefits based on years of service and final average salary. On May 14, 2012, the Company informed its employees of its decision to freeze participation and benefit accruals under the plan, primarily to reduce some of the volatility in earnings that can accompany the maintenance of a defined benefit plan. The plan was frozen on June 30, 2012. Compensation earned by employees up to June 30, 2012 is used for purposes of calculating benefits under the plan but there are no future benefit accruals after this date. Participants as of June 30, 2012 will continue to earn vesting credit with respect to their frozen accrued benefits as they continue to work. In addition, the Company provides certain health and life insurance benefits for a limited number of eligible retired employees. The healthcare plan is contributory with participants’ contributions adjusted annually; the life insurance plan is noncontributory. Employees with less than 14 years of service as of January 1, 1995, are not eligible for the health and life insurance retirement benefits. The composition of net periodic pension plan and postretirement plan costs for the indicated periods is as follows: Pension Benefits Postretirement Benefits Pension Benefits Postretirement Benefits For the three months ended September 30, For the nine months ended September 30, (In thousands) 2017 2016 2017 2016 2017 2016 2017 2016 Service cost $ - $ - $ - $ - $ - $ - $ - $ - Interest cost 118 116 2 2 355 348 6 6 Expected return on plan assets (236 ) (238 ) - - (709 ) (714 ) - - Amortization of net losses/(gains) 39 56 (2 ) (2 ) 115 169 (6 ) (6 ) Net periodic benefit plan benefit $ (79 ) $ (66 ) $ - $ - $ (239 ) $ (197 ) $ - $ - The Company will evaluate the need for further contributions to the defined benefit pension plan during 2017.

Although the Bank has a diversified loan portfolio, a substantial portion of its borrowers’ abilities to honor their loan contracts is dependent upon the counties’ employment and economic conditions. The Bank acquired $15.6 million and $10.2 million of loans originated by an unrelated financial institution, located outside of the Bank’s market area, in January 2017 and April 2017, respectively. The acquired loan pools represented a 90% participating interest in a total of 1,231 loans secured by liens on automobiles with maturities ranging primarily from two to six years. These loans will be serviced through their respective maturities by the originating financial institution. At September 30, 2017 there were 1,131 loans outstanding with a remaining outstanding carrying value of $21.4 million. Since the acquisition of these loan pools, a total of two loans, with a combined outstanding balance of $13,300, have been charged-off as uncollectible. As of September 30, 2017 and December 31, 2016, residential mortgage loans with a carrying value of $148.1 million and $140.3 million, respectively, have been pledged by the Company to the Federal Home Loan Bank of New York (“FHLBNY”) under a blanket collateral agreement to secure the Company’s line of credit and term borrowings. Loan Origination / Risk Management The Company’s lending policies and procedures are presented in Note 5 to the audited consolidated financial statements included in the 2016 Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 31, 2017 and have not changed. As part of the execution of the Company’s overall balance sheet management strategies, the Bank will acquire participating interests in loans originated by unrelated third parties on a sporadic basis. The purchase of participations in loans that are originated by third parties only occurs after the completion of thorough pre-acquisition due diligence. Loans in which the Company acquires a participating interest are determined to meet, in all material respects, the Company’s internal underwriting policies, including credit and collateral suitability thresholds, prior to acquisition. In addition, the financial condition of the originating financial institutions, which are generally retained as the ongoing loan servicing provider for participations acquired by the Bank, are analyzed prior to the acquisition of the participating interests and monitored on a regular basis thereafter for the life of those interests. To develop and document a systematic methodology for determining the allowance for loan losses, the Company has divided the loan portfolio into three portfolio segments, each with different risk characteristics but with similar methodologies for assessing risk. Each portfolio segment is broken down into loan classes where appropriate. Loan classes contain unique measurement attributes, risk characteristics, and methods for monitoring and assessing risk that are necessary to develop the allowance for loan losses. Unique characteristics such as borrower type, loan type, collateral type, and risk characteristics define each class. The following table illustrates the portfolio segments and classes for the Company’s loan portfolio: Portfolio Segment Class Residential Mortgage Loans 1-4 family first-lien residential mortgages Construction Commercial Loans Real estate Lines of credit Other commercial and industrial Tax exempt loans Consumer Loans Home equity and junior liens Other consumer The following tables present the classes of the loan portfolio, not including net deferred loan costs, summarized by the aggregate pass rating and the classified ratings of special mention, substandard and doubtful within the Company's internal risk rating system as of the dates indicated: As of September 30, 2017 Special (In thousands) Pass Mention Substandard Doubtful Total Residential mortgage loans: 1-4 family first-lien residential mortgages $ 204,636 $ 1,050 $ 1,604 $ 1,857 $ 209,147 Construction 5,924 - - - 5,924 Total residential mortgage loans 210,560 1,050 1,604 1,857 215,071 Commercial loans: Real estate 179,951 3,483 3,748 778 187,960 Lines of credit 52,748 280 814 46 53,888 Other commercial and industrial 42,469 566 476 268 43,779 Tax exempt loans 11,064 - - - 11,064 Total commercial loans 286,232 4,329 5,038 1,092 296,691 Consumer loans: Home equity and junior liens 24,783 130 203 292 25,408 Other consumer 29,711 14 8 - 29,733 Total consumer loans 54,494 144 211 292 55,141 Total loans $ 551,286 $ 5,523 $ 6,853 $ 3,241 $ 566,903 As of December 31, 2016 Special (In thousands) Pass Mention Substandard Doubtful Total Residential mortgage loans: 1-4 family first-lien residential mortgages $ 194,377 $ 1,445 $ 2,115 $ 1,063 $ 199,000 Construction 8,505 - - - 8,505 Total residential mortgage loans 202,882 1,445 2,115 1,063 207,505 Commercial loans: Real estate 143,126 3,714 3,858 - 150,698 Lines of credit 49,393 684 400 - 50,477 Other commercial and industrial 39,027 661 702 4 40,394 Tax exempt loans 12,523 - - - 12,523 Total commercial loans 244,069 5,059 4,960 4 254,092 Consumer loans: Home equity and junior liens 23,963 170 389 200 24,722 Other consumer 6,224 17 8 44 6,293 Total consumer loans 30,187 187 397 244 31,015 Total loans $ 477,138 $ 6,691 $ 7,472 $ 1,311 $ 492,612 Management has reviewed its loan portfolio and determined that, to the best of its knowledge, no material exposure exists to sub-prime or other high-risk residential mortgages. The Company is not in the practice of originating these types of loans. At September 30, 2017, there were $3.2 million in loans classified as doubtful as compared to $1.3 million of those loans at December 31, 2016. The $1.9 million increase in loans classified as doubtful at September 30, 2017, as compared to December 31, 2016, was due to increases in loans categorized as doubtful in 1-4 family first-lien residential mortgages, commercial real estate loans, and in all other loan categories in aggregate of $794,000, $778,000 and $358,000, respectively. The $794,000 increase in 1-4 family first-lien residential mortgages classified as doubtful was primarily due to a single loan with an outstanding balance of $406,000, with the remaining balance of $372,000 being comprised of four additional loans. The $778,000 increase in commercial real estate loans classified as doubtful was due to the addition of two loans with aggregate outstanding balances of that amount. The net aggregate increase of $358,000 in loans classified as doubtful in all other loan categories was primarily due to the addition of four commercial and industrial loans, the largest of which had an outstanding balance of $124,000 at September 30, 2017. Management thoroughly reviews all relevant factors in determining the collectability of doubtful loans, including the estimated fair value of the underlying collateral, in determining the adequacy of specific reserves against potential losses arising from doubtful loans. Management believes that it has established sufficient specific reserves within its overall allowance for loan and lease losses to mitigate any material impact to the Company’s financial results related to the future disposition of these loans. Nonaccrual and Past Due Loans Loans are placed on nonaccrual when the contractual payment of principal and interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan may be currently performing. Loans are considered past due if the required principal and interest payments have not been received within thirty days of the payment due date. An age analysis of past due loans, not including net deferred loan costs, segregated by portfolio segment and class of loans, as of September 30, 2017 and December 31, 2016, are detailed in the following tables: As of September 30, 2017 30-59 Days 60-89 Days 90 Days Past Due Past Due and Total Total Loans (In thousands) And Accruing And Accruing Over Past Due Current Receivable Residential mortgage loans: 1-4 family first-lien residential mortgages $ 1,237 $ 676 $ 2,265 $ 4,178 $ 204,969 $ 209,147 Construction - - - - 5,924 5,924 Total residential mortgage loans 1,237 676 2,265 4,178 210,893 215,071 Commercial loans: Real estate 3,868 162 1,635 5,665 182,295 187,960 Lines of credit 992 600 40 1,632 52,256 53,888 Other commercial and industrial 569 139 514 1,222 42,557 43,779 Tax exempt loans - - - - 11,064 11,064 Total commercial loans 5,429 901 2,189 8,519 288,172 296,691 Consumer loans: Home equity and junior liens 185 - 339 524 24,884 25,408 Other consumer 17 14 51 82 29,651 29,733 Total consumer loans 202 14 390 606 54,535 55,141 Total loans $ 6,868 $ 1,591 $ 4,844 $ 13,303 $ 553,600 $ 566,903 As of December 31, 2016 30-59 Days 60-89 Days 90 Days Past Due Past Due and Total Total Loans (In thousands) And Accruing And Accruing Over Past Due Current Receivable Residential mortgage loans: 1-4 family first-lien residential mortgages $ 1,247 $ 832 $ 2,560 $ 4,639 $ 194,361 $ 199,000 Construction - - - - 8,505 8,505 Total residential mortgage loans 1,247 832 2,560 4,639 202,866 207,505 Commercial loans: Real estate 1,063 375 1,223 2,661 148,037 150,698 Lines of credit 819 - - 819 49,658 50,477 Other commercial and industrial 333 - 640 973 39,421 40,394 Tax exempt loans - - - - 12,523 12,523 Total commercial loans 2,215 375 1,863 4,453 249,639 254,092 Consumer loans: Home equity and junior liens 105 157 338 600 24,122 24,722 Other consumer 8 13 50 71 6,222 6,293 Total consumer loans 113 170 388 671 30,344 31,015 Total loans $ 3,575 $ 1,377 $ 4,811 $ 9,763 $ 482,849 $ 492,612 At September 30, 2017, there were $13.3 million in loans past due including $6.9 million in loans 30-59 days past due. At December 31, 2016, there were $9.8 million in loans past due including $3.6 million in loans 30-59 days past due. The increase of $3.5 million in total loans past due at September 30, 2017, as compared to December 31, 2016, was primarily due to an increase of $3.3 million in loans 30-59 days past due. The increase in loans 30-59 days past due at September 30, 2017, as compared to December 31, 2016, was primarily due to one commercial real estate loan with an outstanding balance of $2.0 million that was 30-59 days past due at September 30, 2017. In addition, two commercial lines of credit, with combined balances of $491,000, were added to the 30-59 days past due loans at September 30, 2017. The aggregate remaining increase of $1.0 million in the 30-59 days past due loans at September 30, 2017, as compared to December 31, 2016, was due to a large number of individually immaterial additions and deletions within the 30-59 days past due categories. Nonaccrual loans, segregated by class of loan, were as follows: September 30, December 31, (In thousands) 2017 2016 Residential mortgage loans: 1-4 family first-lien residential mortgages $ 2,265 $ 2,560 2,265 2,560 Commercial loans: Real estate 1,635 1,223 Lines of credit 40 - Other commercial and industrial 514 640 2,189 1,863 Consumer loans: Home equity and junior liens 339 338 Other consumer 51 50 390 388 Total nonaccrual loans $ 4,844 $ 4,811 The Company is required to disclose certain activities related to Troubled Debt Restructurings (“TDR”) in accordance with accounting guidance. Certain loans have been modified in a TDR where economic concessions have been granted to a borrower who is experiencing, or expected to experience, financial difficulties. These economic concessions could include a reduction in the loan interest rate, extension of payment terms, reduction of principal amortization, or other actions that it would not otherwise consider for a new loan with similar risk characteristics. The Company is required to disclose new TDRs for each reporting period for which an income statement is being presented. Pre-modification outstanding recorded investment is the principal loan balance less the provision for loan losses before the loan was modified as a TDR. Post-modification outstanding recorded investment is the principal balance less the provision for loan losses after the loan was modified as a TDR. Additional provision for loan losses is the change in the allowance for loan losses between the pre-modification outstanding recorded investment and post-modification outstanding recorded investment. The table below details loans that have been modified as TDRs for the three months ended September 30, 2017. For the three months ended September 30, 2017 (In thousands) Number of loans Pre-modification outstanding recorded investment Post-modification outstanding recorded investment Additional provision for loan losses Individually evaluated for impairment: Commercial real estate loans 1 $ 2,024 $ 2,024 $ - The table below details loans that have been modified as TDRs for the nine months ended September 30, 2017.

The Company had no loans that have been modified as TDRs for the three months ended September 30, 2016. The table below details loans that have been modified as TDRs for the nine months ended September 30, 2016. For the nine months ended September 30, 2016 (In thousands) Number of loans Pre-modification outstanding recorded investment Post-modification outstanding recorded investment Additional provision for loan losses Collectively evaluated for impairment: Residential mortgage loans 2 $ 97 $ 100 $ - The TDRs collectively evaluated for impairment have been classified as TDRs due to economic concessions granted, which consisted of additional funds advanced without associated increases in collateral, interest rate reductions and extended terms. The Company is required to disclose loans that have been modified as TDRs within the previous 12 months in which there was payment default after the restructuring. The Company defines payment default as any loans 90 days past due on contractual payments. The Company had no loans that had been modified as TDRs during the twelve months prior to September 30, 2017, which had subsequently defaulted during the three months ended September 30, 2017. The Company had one loan that had been modified as a TDR during the twelve months prior to September 30, 2017, which had subsequently defaulted during the nine months ended September 30, 2017 The Company had no loans that had been modified as TDRs during the twelve months prior to September 30, 2016, which had subsequently defaulted during the three or nine months ended September 30, 2016. When the Company modifies a loan within a portfolio segment that is individually evaluated for impairment, a potential impairment is analyzed either based on the present value of the expected future cash flows discounted at the interest rate of the original loan terms or the fair value of the collateral less costs to sell. If it is determined that the value of the loan is less than its recorded investment, then impairment is recognized as a component of the provision for loan losses, an associated increase to the allowance for loan losses or as a charge-off to the allowance for loan losses in the current period.

The qualitative factors include: • Changes in national and local economic trends; • The rate of growth in the portfolio; • Trends of delinquencies and nonaccrual balances; • Changes in loan policy; and • Changes in lending management experience and related staffing. Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. These qualitative factors, applied to each product class, make the evaluation inherently subjective, as it requires material estimates that may be susceptible to significant revision as more information becomes available. Adjustments to the factors are supported through documentation of changes in conditions in a narrative accompanying the allowance for loan losses analysis and calculation. The allocation of the allowance for loan losses summarized on the basis of the Company’s calculation methodology was as follows: September 30, 2017 1-4 family first-lien Residential Other residential construction Commercial Commercial commercial (In thousands) mortgage mortgage real estate lines of credit and industrial Specifically reserved $ 181 $ - $ 14 $ 40 $ 381 Historical loss rate 106 - 121 77 14 Qualitative factors 513 - 3,146 597 673 Total $ 800 $ - $ 3,281 $ 714 $ 1,068 Home equity Other (In thousands) Tax exempt and junior liens consumer Unallocated Total Specifically reserved $ - $ 142 $ - $ - $ 758 Historical loss rate - 48 34 - 400 Qualitative factors 1 300 169 71 5,470 Total $ 1 $ 490 $ 203 $ 71 $ 6,628 September 30, 2016 1-4 family first-lien Residential Other residential construction Commercial Commercial commercial (In thousands) mortgage mortgage real estate lines of credit and industrial Specifically reserved $ 37 $ - $ 835 $ 5 $ 141 Historical loss rate 79 - 84 40 52 Qualitative factors 517 - 2,362 339 1,120 Total $ 633 $ - $ 3,281 $ 384 $ 1,313 Home equity Other (In thousands) Tax exempt and junior liens consumer Unallocated Total Specifically reserved $ - $ 6 $ - $ - $ 1,024 Historical loss rate - 35 23 - 313 Qualitative factors 3 316 132 - 4,789 Total $ 3 $ 357 $ 155 $ - $ 6,126

Commitments And Contingencies Disclosure [Abstract]
Guarantees	Note 9: Guarantees The Company does not issue any guarantees that would require liability recognition or disclosure, other than its standby letters of credit. Generally, all letters of credit, when issued have expiration dates within one year. The credit risk involved in issuing letters of credit is 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. The Company had $2.2 million of standby letters of credit as of September 30, 2017. Management believes that the proceeds obtained through a liquidation of collateral and the enforcement of guarantees would be sufficient to cover the potential amount of future payments required under the corresponding guarantees. The fair value of standby letters of credit was not significant to the Company’s consolidated financial statements.

Fair Value Measurements

Fair Value Measurements	9 Months Ended
	Sep. 30, 2017
Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 10: Fair Value Measurements Accounting guidance related to fair value measurements and disclosures specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair value hierarchy: Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2 – Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 3 – Model-derived valuations in which one or more significant inputs or significant value drivers are unobservable. 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. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs, minimize the use of unobservable inputs, to the extent possible, and considers counterparty credit risk in its assessment of fair value. The Company used the following methods and significant assumptions to estimate fair value: Investment securities: The fair values of securities available-for-sale are obtained from an independent third party and are based on quoted prices on nationally recognized securities exchanges where available (Level 1). If quoted prices are not available, fair values are measured by utilizing matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2). Management made no adjustment to the fair value quotes that were received from the independent third party pricing service. Interest rate swap derivative: The fair value of the interest rate swap derivative is obtained from a third party pricing agent and is calculated based on a discounted cash flow model. All future floating cash flows are projected and both floating and fixed cash flows are discounted to the valuation date. The curve utilized for discounting and projecting is built by obtaining publicly available third party market quotes for various swap maturity terms, and therefore is classified within Level 2 of the fair value hierarchy. The swap agreement presented in the accompanying financial statements expired in the second quarter of 2016 and was not renewed. Impaired loans: Impaired loans are those loans in which the Company has measured impairment based on the fair value of the loan’s collateral or the discounted value of expected future cash flows. Fair value is generally determined based upon market value evaluations by third parties of the properties and/or estimates by management of working capital collateral or discounted cash flows based upon expected proceeds. These appraisals may include up to three approaches to value: the sales comparison approach, the income approach (for income-producing property), and the cost approach. Management modifies the appraised values, if needed, to take into account recent developments in the market or other factors, such as, changes in absorption rates or market conditions from the time of valuation and anticipated sales values considering management’s plans for disposition. Such modifications to the appraised values could result in lower valuations of such collateral. Estimated costs to sell are based on current amounts of disposal costs for similar assets. These measurements are classified as Level 3 within the valuation hierarchy. Impaired loans are subject to nonrecurring fair value adjustment upon initial recognition or subsequent impairment. A portion of the allowance for loan losses is allocated to impaired loans if the value of such loans is deemed to be less than the unpaid balance. Foreclosed real estate: Fair values for foreclosed real estate are initially recorded based on market value evaluations by third parties, less costs to sell (“initial cost basis”). Any write-downs required when the related loan receivable is exchanged for the underlying real estate collateral at the time of transfer to foreclosed real estate are charged to the allowance for loan losses. Values are derived from appraisals, similar to impaired loans, of underlying collateral or discounted cash flow analysis. Subsequent to foreclosure, valuations are updated periodically and assets are marked to current fair value, not to exceed the initial cost basis. In the determination of fair value subsequent to foreclosure, management also considers other factors or recent developments, such as, changes in absorption rates and market conditions from the time of valuation and anticipated sales values considering management’s plans for disposition. Either change could result in adjustment to lower the property value estimates indicated in the appraisals. These measurements are classified as Level 3 within the fair value hierarchy. The following tables summarize assets measured at fair value on a recurring basis as of the indicated dates, segregated by the level of valuation inputs within the hierarchy utilized to measure fair value: September 30, 2017 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Available-for-Sale Portfolio Debt investment securities: US Treasury, agencies and GSEs $ - $ 27,154 $ - $ 27,154 State and political subdivisions - 8,915 - 8,915 Corporate - 7,504 - 7,504 Asset backed securities - 5,092 - 5,092 Residential mortgage-backed - US agency - 32,674 - 32,674 Collateralized mortgage obligations - US agency - 40,813 - 40,813 Collateralized mortgage obligations - Private label - 16,718 - 16,718 Equity investment securities: Common stock - Financial services industry - 221 528 749 Total available-for-sale securities $ - $ 139,091 $ 528 $ 139,619 December 31, 2016 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Available-for-Sale Portfolio Debt investment securities: US Treasury, agencies and GSEs $ - $ 24,184 $ - $ 24,184 State and political subdivisions - 16,481 - 16,481 Corporate - 15,195 - 15,195 Asset backed securities 6,664 6,664 Residential mortgage-backed - US agency - 30,566 - 30,566 Collateralized mortgage obligations - US agency - 40,986 - 40,986 Collateralized mortgage obligations - Private label - 6,577 - 6,577 Equity investment securities: Mutual funds: Ultra short mortgage fund 626 - - 626 Common stock - Financial services industry - 220 456 676 Total available-for-sale securities $ 626 $ 140,873 $ 456 $ 141,955 The changes in Level 3 assets and liabilities measured at estimated fair value on a recurring basis during the three months ended September 30, 2017 were as follows: (In thousands) Common Stock - Financial Services Industry Balance - June 30, 2017 $ 456 Total gains realized/unrealized: Included in earnings - Included in other comprehensive income 72 Settlements - Sales - Balance - September 30, 2017 $ 528 Changes in unrealized gains included in earnings related to assets still held at September 30, 2017 $ - The changes in Level 3 assets and liabilities measured at estimated fair value on a recurring basis during the nine months ended September 30, 2017 were as follows: (In thousands) Common Stock - Financial Services Industry Balance - December 31, 2016 $ 456 Total gains realized/unrealized: Included in earnings - Included in other comprehensive income 72 Settlements - Sales - Balance - September 30, 2017 $ 528 Changes in unrealized gains included in earnings related to assets still held at September 30, 2017 $ - The following table summarizes the valuation techniques and significant unobservable inputs used for the Company's investments that are categorized within Level 3 of the fair value hierarchy at the indicated dates: (In thousands) At September 30, 2017 Investment Type Fair Value Valuation Techniques Unobservable Input Weight Common Stock - Financial Services Industry $ 528 Inputs to comparables Weigh t 100% (In thousands) At December 31, 2016 Investment Type Fair Value Valuation Techniques Unobservable Input Weight Common Stock - Financial Services Industry $ 456 Inputs to comparables Weight ascribed to comparable companies 100% Pathfinder Bank had the following assets measured at fair value on a nonrecurring basis as of September 30, 2017 and December 31, 2016: September 30, 2017 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Impaired loans $ - $ - $ 2,295 $ 2,295 Foreclosed real estate $ - $ - $ 433 $ 433 December 31, 2016 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Impaired loans $ - $ - $ 4,049 $ 4,049 Foreclosed real estate $ - $ - $ 393 $ 393 The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis and for which Level 3 inputs were used to determine fair value at the indicated dates.

Required disclosures include fair value information of financial instruments, whether or not recognized in the consolidated statement of condition, for which it is practicable to estimate that value. 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 and, in many cases, could not be realized in immediate settlement of the instrument. The Company has various processes and controls in place to ensure that fair value is reasonably estimated. The Company performs due diligence procedures over third-party pricing service providers in order to support their use in the valuation process. While the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective period-ends, and have not been re-evaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period-end. 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 Company, in estimating its fair value disclosures for financial instruments, used the following methods and assumptions: Cash and cash equivalents – The carrying amounts of these assets approximate their fair value and are classified as Level 1. Investment securities – The fair values of securities available-for-sale and held-to-maturity are obtained from an independent third party and are based on quoted prices on nationally recognized exchange where available (Level 1). If quoted prices are not available, fair values are measured by utilizing matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities, but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2). Management made no adjustment to the fair value quotes that were received from the independent third party pricing service. Level 3 securities are assets whose Federal Home Loan Bank stock – The carrying amount of these assets approximates their fair value and are classified as Level 2. Net loans – For variable-rate loans that re-price frequently, fair value is based on carrying amounts. The fair value of other loans (for example, fixed-rate commercial real estate loans, mortgage loans, and commercial and industrial loans) is estimated using discounted cash flow analysis, based on interest rates currently being offered in the market for loans with similar terms to borrowers of similar credit quality. Loan value estimates include judgments based on expected prepayment rates. The measurement of the fair value of loans, including impaired loans, is classified within Level 3 of the fair value hierarchy. Accrued interest receivable and payable – The carrying amount of these assets approximates their fair value and are classified as Level 1. Deposits – The fair values disclosed for demand deposits (e.g., interest-bearing and noninterest-bearing checking, passbook savings and certain types of money management accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts) and are classified within Level 1 of the fair value hierarchy. 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 of deposits to a schedule of aggregated expected monthly maturities on time deposits. Measurements of the fair value of time deposits are classified within Level 2 of the fair value hierarchy. Borrowings – Fixed/variable term “bullet” structures are valued using a replacement cost of funds approach. These borrowings are discounted to the FHLBNY advance curve. Option structured borrowings’ fair values are determined by the FHLB for borrowings that include a call or conversion option. If market pricing is not available from this source, current market indications from the FHLBNY are obtained and the borrowings are discounted to the FHLBNY advance curve less an appropriate spread to adjust for the option. These measurements are classified as Level 2 within the fair value hierarchy. Subordinated loans – The Company secures quotes from its pricing service based on a discounted cash flow methodology or utilizes observations of recent highly-similar transactions which result in a Level 2 classification. Interest rate swap derivative – The fair value of the interest rate swap derivative is obtained from a third party pricing agent and is calculated based on a discounted cash flow model. All future floating cash flows are projected and both floating and fixed cash flows are discounted to the valuation date. The curve utilized for discounting and projecting is built by obtaining publicly available third party market quotes for various swap maturity terms, and therefore is classified within Level 2 of the fair value hierarchy.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Interest Rate Derivatives	Note 11: Interest Rate Derivatives Derivative instruments are entered into by the Company primarily as a risk management tool. Financial derivatives are recorded at fair value as other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability are recognized currently in earnings. For a cash flow hedge, changes in the fair value of the derivative instrument, to the extent that it is effective, are recorded in other comprehensive income and subsequently reclassified to earnings as the hedged transaction impacts net income. Any ineffective portion of a cash flow hedge is recognized currently in earnings. See Note 10 for further discussion of the fair value of the interest rate derivative. The Company has $5.0 million of floating rate trust preferred debt indexed to 3-month LIBOR. As a result, it is exposed to variability in cash flows related to changes in projected interest payments caused by changes in the benchmark interest rate. During the fourth quarter of fiscal 2009, the Company entered into an interest rate swap agreement, with a $2.0 million notional amount, to convert a portion of the floating rate trust preferred debt to a fixed rate for a term of approximately seven years at a rate of 4.96%. This swap agreement expired in the second quarter of 2016 and was not renewed. The derivative, while in effect, was designated as a cash flow hedge. The hedging strategy ensured that changes in cash flows from the derivative would have been highly effective at offsetting changes in interest expense from the hedged exposure. On four occasions during the first half of 2017, the Company sold, and subsequently repurchased, a U.S. Treasury security in the approximate amount of $40.0 million for each transaction. These transactions were intended to act as hedges against rising short-term interest rates. The Company was in controlling possession of, but did not own, the securities at the time of each sale. The securities had been received by the Company, under industry-standard repurchase agreements, from an unrelated third party as collateral for a series of 30-day loans of approximately $40.0 million on each occasion which were made at market rates of interest to that third party. The security sale on each occasion provided the funds necessary to advance the loan to the third party and placed the Company in what is generally described as a “short position” with respect to the sold U.S. Treasury security. These transactions acted as a hedge against rising short-term interest rates because the price of each sold security would be expected to decline in a rising short-term interest rate environment and could therefore be re-acquired at the conclusion of each 30-day loan period at a price lower than the price at which the security was originally sold. Short-term rates rose over the combined duration of these transactions and, consequently, the Company recognized aggregate gains on the sale and repurchase of the securities in the amounts of $250,000 for the nine months ended September 30, 2017. The transactions’ gains were characterized as capital gains for tax purposes. These capital gains utilized existing, previously reserved-for, capital loss tax carryforwards that were established in 2013. The Company recognized tax benefits related to these transactions of $96,000 for the nine months ended September 30, 2017. The tax benefits arose from the reversal of reserves established in 2013 against the portion of the Company’s deferred tax asset related to existing capital loss carryforward positions. The reserves were originally established due to the uncertainty of the Company’s ability to generate future capital gain income within the five-year statutory life of the capital loss carryforward position under the Internal Revenue Code. The recognized tax benefit from the reversal of those reserves reduced the Company’s effective tax rate from what would have been The capital gain income and the additional recognized tax benefits derived from these transactions were partially offset by an additional $266,000 in after-tax interest expense on borrowings derived from additional pre-tax interest expense on those borrowings of $430,000 that reduced pretax net interest margin by that amount in the nine month period. In total, after-tax net income increased by $80,000 for the nine months ended September 30, 2017 as a result of these hedging transactions. The Company initially incurred consulting and placement fees of $128,000 related to these transactions, of which $49,000 has been charged to interest expense and included in the additional interest expense totals discussed above. The remaining $79,000 in consulting and placement fees has been recorded on the Company’s Consolidated Statements of Condition at September 30, 2017 as deferred fees and will be recognized ratably as interest expense on the occasions that this hedging position is reestablished in future periods. The hedge position was closed as of June 30, 2017 and was not reopened during the third quarter of 2017. Other than the deferred fees of $79,000 discussed above, these hedging activities had no effect on the Company’s consolidated financial condition at September 30, 2017.
