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.

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 three three 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 57% March 31, 2017) 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. The scope of loans reviewed individually each quarter to determine if they are impaired include all loan relationships greater than $200,000 one not March 31, 2017 December 31, 2016. $200,000 $100,000 The following tables present a summary of loan balances and the related allowance for loan losses summarized by portfolio segment and class for each impairment method used as of March 31, 2017 December 31, 2016: March 31, 2017 Loans: Allowance for Loan Losses: (In Thousands) Individually Collectively Individually Collectively Evaluated Evaluated Totals Evaluated Evaluated Totals Residential mortgage: Residential mortgage loans - first liens $ 743 $ 339,688 $ 340,431 $ 0 $ 3,125 $ 3,125 Residential mortgage loans - junior liens 66 23,651 23,717 0 256 256 Home equity lines of credit 0 36,810 36,810 0 338 338 1-4 Family residential construction 0 24,041 24,041 0 240 240 Total residential mortgage 809 424,190 424,999 0 3,959 3,959 Commercial: Commercial loans secured by real estate 5,915 147,470 153,385 753 1,932 2,685 Commercial and industrial 162 79,331 79,493 77 829 906 Political subdivisions 0 44,625 44,625 0 0 0 Commercial construction and land 0 15,252 15,252 0 169 169 Loans secured by farmland 1,387 6,110 7,497 51 60 111 Multi-family (5 or more) residential 392 7,230 7,622 0 236 236 Agricultural loans 12 3,980 3,992 0 39 39 Other commercial loans 0 11,131 11,131 0 109 109 Total commercial 7,868 315,129 322,997 881 3,374 4,255 Consumer 22 14,003 14,025 0 132 132 Unallocated 398 Total $ 8,699 $ 753,322 $ 762,021 $ 881 $ 7,465 $ 8,744 December 31, 2016 Loans: Allowance for Loan Losses: (In Thousands) Individually Collectively Individually Collectively Evaluated Evaluated Totals Evaluated Evaluated Totals Residential mortgage: Residential mortgage loans - first liens $ 753 $ 333,349 $ 334,102 $ 0 $ 3,033 $ 3,033 Residential mortgage loans - junior liens 68 23,638 23,706 0 258 258 Home equity lines of credit 0 38,057 38,057 0 350 350 1-4 Family residential construction 0 24,908 24,908 0 249 249 Total residential mortgage 821 419,952 420,773 0 3,890 3,890 Commercial: Commercial loans secured by real estate 8,005 142,463 150,468 528 1,852 2,380 Commercial and industrial 212 83,642 83,854 95 904 999 Political subdivisions 0 38,068 38,068 0 0 0 Commercial construction and land 0 14,287 14,287 0 162 162 Loans secured by farmland 1,394 5,900 7,294 51 59 110 Multi-family (5 or more) residential 392 7,504 7,896 0 241 241 Agricultural loans 13 3,985 3,998 0 40 40 Other commercial loans 0 11,475 11,475 0 115 115 Total commercial 10,016 307,324 317,340 674 3,373 4,047 Consumer 23 13,699 13,722 0 138 138 Unallocated 398 Total $ 10,860 $ 740,975 $ 751,835 $ 674 $ 7,401 $ 8,473 Summary information related to impaired loans at March 31, 2017 December 31, 2016 (In Thousands) March 31, 2017 December 31, 2016 Unpaid Unpaid Principal Recorded Related Principal Recorded Related Balance Investment Allowance Balance Investment Allowance With no related allowance recorded: Residential mortgage loans - first liens $ 773 $ 743 $ 0 $ 783 $ 753 $ 0 Residential mortgage loans - junior liens 66 66 0 68 68 0 Commercial loans secured by real estate 3,175 3,175 0 6,975 5,232 0 Commercial and industrial 85 85 0 117 117 0 Loans secured by farmland 885 885 0 890 890 0 Multi-family (5 or more) residential 987 392 0 987 392 0 Agricultural loans 12 12 0 13 13 0 Consumer 22 22 0 23 23 0 Total with no related allowance recorded 6,005 5,380 0 9,856 7,488 0 With a related allowance recorded: Commercial loans secured by real estate 2,740 2,740 753 2,773 2,773 528 Commercial and industrial 77 77 77 95 95 95 Loans secured by farmland 502 502 51 504 504 51 Total with a related allowance recorded 3,319 3,319 881 3,372 3,372 674 Total $ 9,324 $ 8,699 $ 881 $ 13,228 $ 10,860 $ 674 The average balance of impaired loans and interest income recognized on impaired loans is as follows: Interest Income Recognized on Average Investment in Impaired Loans Impaired Loans on a Cash Basis (In Thousands) 3 Months Ended 3 Months Ended March 31, March 31, 2017 2016 2017 2016 Residential mortgage: Residential mortgage loans - first lien $ 748 $ 861 $ 9 $ 10 Residential mortgage loans - junior lien 67 73 1 1 Total residential mortgage 815 934 10 11 Commercial: Commercial loans secured by real estate 6,889 6,160 56 110 Commercial and industrial 247 568 3 3 Loans secured by farmland 1,390 1,423 8 21 Multi-family (5 or more) residential 392 690 0 0 Agricultural loans 12 15 1 1 Total commercial 8,930 8,856 68 135 Consumer 33 12 0 0 Total $ 9,778 $ 9,802 $ 78 $ 146 Loans are placed on nonaccrual status for all classes of loans when, in the opinion of management, collection of interest is doubtful.

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 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 $320,661,000 March 31, 2017.

Accounting Changes and Error Corrections [Text Block]	13. 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 In May 2014, 2014 09, five ● In August 2015 2015 14, first 2018 December 31, 2018. ● In April 2016, 2016 10, ● In May 2016, 2016 12 December 2016, 2016 20, ● In February 2017, 2017 05, 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. Initial adoption of this ASU is not expected to have a significant impact on the Corporation, as recognition of interest income and the larger sources of noninterest income in the Corporation’s current business model would not be impacted by the ASU. In January 2016, 2016 01, (1) may (2) (3) (4) (5) March 31, 2017 December 31, 2016, (6) (7) first 2018. In February 2016, 2016 02, 842). 842 12 842 842 842 842 first 2019. In March 2016, 2016 07, first 2017. 2017 In March 2016, 2016 09, may (1) (2) (3) (4) (5) first 2017, 2017 In June 2016, 2016 13, 326). ● 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 2020. first 2019. 326 The Corporation is in the early stages of evaluating the potential impact of adopting this amendment.
