New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (a new revenue recognition standard). The core principle of the update is that a company will recognize revenue to depict the transfer of 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 addition, this update specifies the accounting for certain costs to obtain or fulfill a contract with a customer and expands disclosure requirements for revenue recognition. This update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the impact the adoption of the standard will have on the Company's financial position or results of operation. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This update applies to all entities that hold financial assets or owe financial liabilities and is intended to provide more useful information on the recognition, measurement, presentation, and disclosure of financial instruments. Among other things, this update (a) requires 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; (b) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (c) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; (d) eliminates 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; (e) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (f) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; (g) requires 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 (h) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. For all other entities including not-for-profit entities and employee benefit plans within the scope of Topics 960 through 965 on plan accounting, the amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. All entities that are not public business entities may adopt the amendments in this update earlier as of the fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . The standard requires lessees to recognize the assets and liabilities that arise from leases on the balance sheet. A lessee should recognize in the statement of financial position 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. A short-term lease is defined as one in which: (a) the lease term is 12 months or less, and (b) there is not an option to purchase the underlying asset that the lessee is reasonably certain to exercise. For short-term leases, lessees may elect to recognize lease payments over the lease term on a straight-line basis. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, and interim periods within those years. For all other entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, and for interim periods within fiscal years beginning after December 15, 2020. The amendments should be applied at the beginning of the earliest period presented using a modified retrospective approach with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is currently assessing the practical expedients it may elect at adoption, but does not anticipate the amendments will have a significant impact on the financial statements. Based on the Company's preliminary analysis of its current portfolio, the impact to the Company's balance sheet is estimated to result in less than a 1 percent increase in assets and liabilities. The Company also anticipates additional disclosures to be provided at adoption, or this update is not expected to have a significant impact on the Company's financial statements. In March 2016, the FASB issued ASU 2016-04, Liabilities - Extinguishments of Liabilities (Subtopic 405-20). The standard provides that liabilities related to the sale of prepaid stored-value products within the scope of this Update are financial liabilities. The amendments in the Update provide a narrow scope exception to the guidance in Subtopic 405-20 to require that breakage for those liabilities be accounted for consistent with the breakage guidance in Topic 606. The amendments in this update are effective for public business entities, certain not-for-profit entities, and certain employee benefit plans for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For all other entities, the amendments are effective for financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Earlier application is permitted, including adoption in an interim period. This update is not expected to have a significant impact on the Company’s financial statements. In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815) . The amendments in this update apply to all reporting entities for which there is a change in the counterparty to a derivative instrument that has been designated as a hedging instrument under Topic 815 . The standards in this Update clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815 does not, in and of itself, require designation of that hedging relationship provided that all other hedge accounting criteria continue to be met. For public business entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. For all other entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within fiscal years beginning after December 15, 2018. An entity has an option to apply the amendments in this Update on either a prospective basis or a modified retrospective basis. Early adoption is permitted, including adoption in an interim period. This Update is not expected to have a significant impact on the Company’s financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets. This ASU is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The underlying premise of the ASU is that financial assets measured at amortized cost should be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The allowance for credit losses should reflect management’s current estimate of credit losses that are expected to occur over the remaining life of a financial asset. The income statement will be effected for the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted for annual and interim periods beginning after December 15, 2018. With certain exceptions, transition to the new requirements will be through a cumulative effect adjustment to opening retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which addresses eight specific cash flow issues with the objective of reducing diversity in practice. Among these include recognizing cash payments for debt prepayment or debt extinguishment as cash outflows for financing activities; cash proceeds received from the settlement of insurance claims should be classified on the basis of the related insurance coverage; and cash proceeds received from the settlement of bank-owned life insurance policies should be classified as cash inflows from investing activities while the cash payments for premiums on bank-owned policies may be classified as cash outflows for investing activities, operating activities, or a combination of investing and operating activities. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The amendments in this Update should be applied using a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s statement of cash flows. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740) , which requires recognition of current and deferred income taxes resulting from an intra-entity transfer of any asset (excluding inventory) when the transfer occurs. Consequently, the amendments in this Update eliminate the exception for an intra-entity transfer of an asset other than inventory. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those annual reporting periods. For all other entities, the amendments are effective for annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual periods beginning after December 15, 2019. Early adoption is permitted for all entities as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. That is, earlier adoption should be in the first interim period if an entity issues interim financial statements. The amendments in this Update should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. This Update is not expected to have a significant impact on the Company’s financial statements. In October 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) , which requires that a statement of cash flows explains the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s statement of cash flows. In December 2016, the FASB issued ASU 2016-20 , Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers . This Update, among others things, clarifies that guarantee fees within the scope of Topic 460, Guarantees , (other than product or service warranties) are not within the scope of Topic 606. The effective date and transition requirements for ASU 2016-20 are the same as the effective date and transition requirements for the new revenue recognition guidance. For public entities with a calendar year-end, the new guidance is effective in the quarter and year beginning January 1, 2018. For all other entities with a calendar year-end, the new guidance is effective in the year ending December 31, 2019, and interim periods in 2020. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business , which provides a more robust framework to use in determining when a set of assets and activities (collectively referred to as a “set”) is a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. Public business entities should apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods within those periods. All other entities should apply the amendments to annual periods beginning after December 15, 2018, and interim periods within annual periods beginning after December 15, 2019. The amendments in this Update should be applied prospectively on or after the effective date. This Update is not expected to have a significant impact on the Company’s financial statements. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment . To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this Update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting units fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. A public business entity that is a U.S. Securities and Exchange Commission (“SEC”) filer should adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. A public business entity that is not an SEC filer should adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2020. All other entities, including not-for-profit entities, that are adopting the amendments in this Update should do so for their annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2021. In February 2017, the FASB issued ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) . The amendments in this Update clarify what constitutes a financial asset within the scope of Subtopic 610-20. The amendments also clarify that entities should identify each distinct nonfinancial asset or in substance nonfinancial asset that is promised to a counterparty and to derecognize each asset when the counterparty obtains control. There is also additional guidance provided for partial sales of a nonfinancial asset and when derecognition, and the related gain or loss, should be recognized. The amendments in this Update are effective at the same time as the amendments in Update 2014-09. Therefore, for public entities, the amendments are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. For all other entities, the amendments in this Update are effective for annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. In February 2017, the FASB issued ASU 2017-06 , Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), and Health and Welfare Benefit Plans (Topic 965) . This Update relates primarily to the reporting by an employee benefit plan for its interest in a master trust, which is a trust for which a regulated financial institution serves as a trustee or custodian and in which assets of more than one plan sponsored by a single employer or by a group of employers under common control are held. For each master trust in which a plan holds an interest, the amendments in this Update require a plan's interest in that master trust and any change in that interest to be presented in separate line items in the statement of net assets available for benefits and in the statement of changes in net assets available for benefits, respectively. The amendments in this Update remove the requirement to disclose the percentage interest in the master trust for plans with divided interests and require that all plans disclose the dollar amount of their interest in each of those general types of investments, which supplements the existing requirement to disclose the master trusts balances in each general type of investments. There are also increased disclosure requirements for investments in master trusts. The amendments in this Update are effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20). The amendments in this Update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. 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 adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosures about a change in accounting principle. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

Earnings Per Share [Abstract]
Per Share Data	Per Share Data There are no convertible securities which would affect the denominator in calculating basic and dilutive earnings per share. There were a total of 96,500 stock options, with an average exercise price of $43.61 , outstanding on March 31, 2017 . These options were included, on a weighted average basis, in the computation of diluted earnings per share for the period due to the average market price of common shares of $46.94 being in excess of the exercise price of the options. There were a total of 32,500 stock options outstanding for the same period end in 2016 that had an average exercise price of $42.03 and were excluded from the computation of diluted earnings per share because the average market price of common shares was $39.02 for the period. Net income as presented on the consolidated statement of income will be used as the numerator. The following table sets forth the composition of the weighted average common shares (denominator) used in the basic and dilutive earnings per share computation.

Loans and Leases Receivable Disclosure [Abstract]
Loans	Loans Management segments the Banks' loan portfolio to a level that enables risk and performance monitoring according to similar risk characteristics. Loans are segmented based on the underlying collateral characteristics. Categories include commercial, financial, and agricultural, real estate, and installment loans to individuals. Real estate loans are further segmented into three categories: residential, commercial, and construction. The following table presents the related aging categories of loans, by segment, as of March 31, 2017 and December 31, 2016 : March 31, 2017 Past Due Past Due 90 30 To 89 Days Or More Non- (In Thousands) Current Days & Still Accruing Accrual Total Commercial, financial, and agricultural $ 141,648 $ 277 $ 9 $ 128 $ 142,062 Real estate mortgage: Residential 558,068 5,244 — 1,899 565,211 Commercial 302,700 671 132 8,682 312,185 Construction 37,289 101 — — 37,390 Installment loans to individuals 54,950 605 — 21 55,576 1,094,655 $ 6,898 $ 141 $ 10,730 1,112,424 Net deferred loan fees and discounts (1,324 ) (1,324 ) Allowance for loan losses (12,905 ) (12,905 ) Loans, net $ 1,080,426 $ 1,098,195 December 31, 2016 Past Due Past Due 90 30 To 89 Days Or More Non- (In Thousands) Current Days & Still Accruing Accrual Total Commercial, financial, and agricultural $ 145,179 $ 785 $ 14 $ 132 $ 146,110 Real estate mortgage: Residential 553,053 9,112 587 1,988 564,740 Commercial 296,537 786 268 8,591 306,182 Construction 33,879 771 — — 34,650 Installment loans to individuals 43,008 202 1 45 43,256 1,071,656 $ 11,656 $ 870 $ 10,756 1,094,938 Net deferred loan fees and discounts (1,257 ) (1,257 ) Allowance for loan losses (12,896 ) (12,896 ) Loans, net $ 1,057,503 $ 1,080,785 Purchased loans acquired are recorded at fair value on their purchase date without a carryover of the related allowance for loan losses. Upon the acquisition of Luzerne Bank on June 1, 2013, the Company evaluated whether each acquired loan (regardless of size) was within the scope of ASC 310-30, Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality . Purchased credit-impaired loans are loans that have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments. There were no material increases or decreases in the expected cash flows of these loans between June 1, 2013 (the “acquisition date”) and March 31, 2017 . The fair value of purchased credit-impaired loans, on the acquisition date, was determined, primarily based on the fair value of loan collateral. On the acquisition date, the preliminary estimate of the unpaid principal balance for all loans evidencing credit impairment acquired in the Luzerne Bank acquisition was $1,211,000 and the estimated fair value of the loans was $878,000 . Total contractually required payments on these loans, including interest, at the acquisition date was $1,783,000 . However, the Company’s preliminary estimate of expected cash flows was $941,000 . At such date, the Company established a credit risk related non-accretable discount (a discount representing amounts which are not expected to be collected from either the customer or liquidation of collateral) of $842,000 relating to these impaired loans, reflected in the recorded net fair value. Such amount is reflected as a non-accretable fair value adjustment to loans. The Company further estimated the timing and amount of expected cash flows in excess of the estimated fair value and established an accretable discount of $63,000 on the acquisition date relating to these impaired loans. The following table presents interest income the Banks would have recorded if interest had been recorded based on the original loan agreement terms and rate of interest for non-accrual loans and interest income recognized on a cash basis for non-accrual loans for the three months ended March 31, 2017 and 2016 : Three Months Ended March 31, 2017 2016 (In Thousands) Interest Income That Would Have Been Recorded Based on Original Term and Rate Interest Income Recorded on a Cash Basis Interest Income That Would Have Been Recorded Based on Original Term and Rate Interest Income Recorded on a Cash Basis Commercial, financial, and agricultural $ 6 $ — $ 4 $ 1 Real estate mortgage: Residential 151 101 32 14 Commercial 496 105 169 64 Construction — — 6 — $ 653 $ 206 $ 211 $ 79 Impaired Loans Impaired loans are loans for which it is probable the Banks will not be able to collect all amounts due according to the contractual terms of the loan agreement. The Banks evaluate such loans for impairment individually and does not aggregate loans by major risk classifications. The definition of “impaired loans” is not the same as the definition of “non-accrual loans,” although the two categories overlap. The Banks may choose to place a loan on non-accrual status due to payment delinquency or uncertain collectability, while not classifying the loan as impaired. Factors considered by management in determining impairment include payment status and collateral value. The amount of impairment for these types of loans is determined by the difference between the present value of the expected cash flows related to the loan, using the original interest rate, and its recorded value, or as a practical expedient in the case of collateralized loans, the difference between the fair value of the collateral and the recorded amount of the loan. When foreclosure is probable, impairment is measured based on the fair value of the collateral. Management evaluates individual loans in all of the commercial segments for possible impairment if the loan is greater than $100,000 and if the loan is either on non-accrual status or has a risk rating of substandard. Management may also elect to measure an individual loan for impairment if less than $100,000 on a case-by-case basis. Mortgage loans on one-to-four family properties and all consumer loans are large groups of smaller-balance homogeneous loans and are measured for impairment collectively. Loans that experience insignificant payment delays, which are defined as 90 days or less, generally are not classified as impaired. Management determines the significance of payment delays on a case-by-case basis taking into consideration all circumstances surrounding the loan and the borrower including the length of the delay, the borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed. Interest income for impaired loans is recorded consistent with the Banks' policy on non-accrual loans. The following table presents the recorded investment, unpaid principal balance, and related allowance of impaired loans by segment as of March 31, 2017 and December 31, 2016 : March 31, 2017 Recorded Unpaid Principal Related (In Thousands) Investment Balance Allowance With no related allowance recorded: Commercial, financial, and agricultural $ 55 $ 55 $ — Real estate mortgage: Residential 1,563 1,563 — Commercial 1,564 1,564 — Installment loans to individuals — — — 3,182 3,182 — With an allowance recorded: Commercial, financial, and agricultural 129 129 74 Real estate mortgage: Residential 1,674 1,674 567 Commercial 10,571 10,666 1,723 Installment loans to individuals 4 4 4 12,378 12,473 2,368 Total: Commercial, financial, and agricultural 184 184 74 Real estate mortgage: Residential 3,237 3,237 567 Commercial 12,135 12,230 1,723 Installment loans to individuals 4 4 4 $ 15,560 $ 15,655 $ 2,368 December 31, 2016 Recorded Unpaid Principal Related (In Thousands) Investment Balance Allowance With no related allowance recorded: Commercial, financial, and agricultural $ 109 $ 109 $ — Real estate mortgage: Residential 1,584 1,584 — Commercial 1,833 1,833 — Installment loans to individuals — — — 3,526 3,526 — With an allowance recorded: Commercial, financial, and agricultural 132 132 74 Real estate mortgage: Residential 1,893 1,893 437 Commercial 10,425 10,520 1,668 Installment loans to individuals — — — 12,450 12,545 2,179 Total: Commercial, financial, and agricultural 241 241 74 Real estate mortgage: Residential 3,477 3,477 437 Commercial 12,258 12,353 1,668 Installment loans to individuals — — — $ 15,976 $ 16,071 $ 2,179 The following table presents the average recorded investment in impaired loans and related interest income recognized for the three months ended for March 31, 2017 and 2016 : Three Months Ended March 31, 2017 2016 (In Thousands) Average Investment in Impaired Loans Interest Income Recognized on an Accrual Basis on Impaired Loans Interest Income Recognized on a Cash Basis on Impaired Loans Average Investment in Impaired Loans Interest Income Recognized on an Accrual Basis on Impaired Loans Interest Income Recognized on a Cash Basis on Impaired Loans Commercial, financial, and agricultural $ 212 $ 4 $ — $ 533 $ 4 $ 1 Real estate mortgage: Residential 3,258 22 16 2,899 22 14 Commercial 11,946 33 10 12,829 82 63 Construction — — — 245 — 1 Installment loans to individuals 2 — — — — — $ 15,418 $ 59 $ 26 $ 16,506 $ 108 $ 79 Currently, there is $26,000 committed to be advanced in connection with impaired loans. Troubled Debt Restructurings The loan portfolio also includes certain loans that have been modified in a Troubled Debt Restructuring (“TDR”), where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties. These concessions typically result from loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance, or other actions. Certain TDRs are classified as nonperforming at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months . There were no loan modifications that were considered TDRs completed during the three months ended March 31 for both 2017 and 2016. There were no loan modifications considered to be TDRs made during the twelve months previous to March 31, 2017 that defaulted during the three months ended March 31, 2017 . There were five loan modifications considered TDRs made during the twelve months previous to March 31, 2016 that defaulted during the three months ended March 31, 2016 . The defaulted loan types and recorded investments at March 31, 2016 are as follows: one commercial loan with a recorded investment of $103,000 , one commercial real estate loan with a recorded investment of $239,000 , and three residential real estate loan with a recorded investment of $173,000 . Troubled debt restructurings amounted to $8,998,000 and $9,180,000 as of March 31, 2017 and December 31, 2016 . The amount of foreclosed residential real estate held at March 31, 2017 and December 31, 2016 , totaled $547,000 and 839,000 , respectively. Consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process at March 31, 2017 and December 31, 2016 , totaled $78,000 and 167,000 , respectively. Internal Risk Ratings Management uses a ten point internal risk rating system to monitor the credit quality of the overall loan portfolio. The first six categories are considered not criticized, and are aggregated as “Pass” rated. The criticized rating categories utilized by management generally follow bank regulatory definitions. The special mention category includes assets that are currently protected but are potentially weak, resulting in an undue and unwarranted credit risk, but not to the point of justifying a substandard classification. Loans in the substandard category have well-defined weaknesses that jeopardize the liquidation of the debt, and have a distinct possibility that some loss will be sustained if the weaknesses are not corrected. All loans greater than 90 days past due are evaluated for substandard classification. Loans in the doubtful category exhibit the same weaknesses found in the substandard loans, however, the weaknesses are more pronounced. Such loans are static and collection in full is improbable. However, these loans are not yet rated as loss because certain events may occur which would salvage the debt. Loans classified loss are considered uncollectible and charge-off is imminent. To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Banks have a structured loan rating process with several layers of internal and external oversight. Generally, consumer and residential mortgage loans are included in the pass category unless a specific action, such as bankruptcy, repossession, or death occurs to raise awareness of a possible credit event. An external annual loan review of large commercial relationships is performed, as well as a sample of smaller transactions. Confirmation of the appropriate risk category is included in the review. Detailed reviews, including plans for resolution, are performed on loans classified as substandard, doubtful, or loss on a quarterly basis. The following table presents the credit quality categories identified above as of March 31, 2017 and December 31, 2016 : March 31, 2017 Commercial, Financial, and Agricultural Real Estate Mortgages Installment Loans to Individuals (In Thousands) Residential Commercial Construction Totals Pass $ 136,886 $ 561,995 $ 283,564 $ 37,236 $ 55,576 $ 1,075,257 Special Mention 2,852 850 9,907 — — 13,609 Substandard 2,324 2,366 18,714 154 — 23,558 $ 142,062 $ 565,211 $ 312,185 $ 37,390 $ 55,576 $ 1,112,424 December 31, 2016 Commercial, Financial, and Agricultural Real Estate Mortgages Installment Loans to Individuals (In Thousands) Residential Commercial Construction Totals Pass $ 140,497 $ 561,440 $ 277,916 $ 34,493 $ 43,256 $ 1,057,602 Special Mention 2,943 740 11,143 — — 14,826 Substandard 2,670 2,560 17,123 157 — 22,510 $ 146,110 $ 564,740 $ 306,182 $ 34,650 $ 43,256 $ 1,094,938 Allowance for Loan Losses An allowance for loan losses (“ALL”) is maintained to absorb losses from the loan portfolio. The ALL is based on management’s continuing evaluation of the risk characteristics and credit quality of the loan portfolio, assessment of current economic conditions, diversification and size of the portfolio, adequacy of collateral, past and anticipated future loss experience, and the amount of non-performing loans. The Banks' methodology for determining the ALL is based on the requirements of ASC Section 310-10-35 for loans individually evaluated for impairment (previously discussed) and ASC Subtopic 450-20 for loans collectively evaluated for impairment, as well as the Interagency Policy Statements on the Allowance for Loan and Lease Losses and other bank regulatory guidance. The total of the two components represents the Banks' ALL. Loans that are collectively evaluated for impairment are analyzed with general allowances being made as appropriate. Allowances are segmented based on collateral characteristics previously disclosed, and consistent with credit quality monitoring. Loans that are collectively evaluated for impairment are grouped into two classes for evaluation. A general allowance is determined for “Pass” rated credits, while a separate pool allowance is provided for “Criticized” rated credits that are not individually evaluated for impairment. For the general allowances, historical loss trends are used in the estimation of losses in the current portfolio. These historical loss amounts are modified by other qualitative factors. A historical charge-off factor is calculated utilizing a twelve quarter moving average. However, management may adjust the moving average time frame by up to four quarters to adjust for variances in the economic cycle. Management has identified a number of additional qualitative factors which it uses to supplement the historical charge-off factor because these factors are likely to cause estimated credit losses associated with the existing loan pools to differ from historical loss experience. The additional factors that are evaluated quarterly and updated using information obtained from internal, regulatory, and governmental sources are: national and local economic trends and conditions; levels of and trends in delinquency rates and non-accrual loans; trends in volumes and terms of loans; effects of changes in lending policies; experience, ability, and depth of lending staff; value of underlying collateral; and concentrations of credit from a loan type, industry and/or geographic standpoint. Loans in the criticized pools, which possess certain qualities or characteristics that may lead to collection and loss issues, are closely monitored by management and subject to additional qualitative factors. Management also monitors industry loss factors by loan segment for applicable adjustments to actual loss experience. Management reviews the loan portfolio on a quarterly basis in order to make appropriate and timely adjustments to the ALL. When information confirms all or part of specific loans to be uncollectible, these amounts are promptly charged off against the ALL.

The Company grants commercial, industrial, residential, and installment loans to customers primarily throughout north-east and central Pennsylvania. Although the Company has a diversified loan portfolio, a substantial portion of its debtors’ ability to honor their contracts is dependent on the economic conditions within this region. The Company has a concentration of the following to gross loans at March 31, 2017 and 2016 : March 31, 2017 2016 Owners of residential rental properties 16.29 % 16.27 % Owners of commercial rental properties 14.66 % 14.27 % The following table presents the balance in the allowance for loan losses and the recorded investment in loans by portfolio segment based on impairment method as of March 31, 2017 and December 31, 2016 : March 31, 2017 Commercial, Financial, and Agricultural Real Estate Mortgages Installment Loans to Individuals Unallocated (In Thousands) Residential Commercial Construction Totals Allowance for Loan Losses: Ending allowance balance attributable to loans: Individually evaluated for impairment $ 74 $ 567 $ 1,723 $ — $ 4 $ — $ 2,368 Collectively evaluated for impairment 1,367 5,004 2,743 187 544 692 10,537 Total ending allowance balance $ 1,441 $ 5,571 $ 4,466 $ 187 $ 548 $ 692 $ 12,905 Loans: Individually evaluated for impairment $ 184 $ 3,237 $ 12,135 $ — $ 4 $ 15,560 Collectively evaluated for impairment 141,878 561,974 300,050 37,390 55,572 1,096,864 Total ending loans balance $ 142,062 $ 565,211 $ 312,185 $ 37,390 $ 55,576 $ 1,112,424 December 31, 2016 Commercial, Financial, and Agricultural Real Estate Mortgages Installment Loans to Individuals Unallocated (In Thousands) Residential Commercial Construction Totals Allowance for Loan Losses: Ending allowance balance attributable to loans: Individually evaluated for impairment $ 74 $ 437 $ 1,668 $ — $ — $ — $ 2,179 Collectively evaluated for impairment 1,480 4,946 3,307 178 416 390 10,717 Total ending allowance balance $ 1,554 $ 5,383 $ 4,975 $ 178 $ 416 $ 390 $ 12,896 Loans: Individually evaluated for impairment $ 241 $ 3,477 $ 12,258 $ — $ — $ 15,976 Collectively evaluated for impairment 145,869 561,263 293,924 34,650 43,256 1,078,962 Total ending loans balance $ 146,110 $ 564,740 $ 306,182 $ 34,650 $ 43,256 $ 1,094,938

Off Balance Sheet Risk
Off Balance Sheet Risk	Off Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments are primarily comprised of commitments to extend credit, standby letters of credit, and credit exposure from the sale of assets with recourse. These instruments involve, to varying degrees, elements of credit, interest rate, or liquidity risk in excess of the amount recognized in the Consolidated Balance Sheet. The contract amounts of these instruments express the extent of involvement the Company has in particular classes of financial instruments. The Company’s exposure to credit loss from nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company may require collateral or other security to support financial instruments with off-balance sheet credit risk. Financial instruments whose contract amounts represent credit risk are as follows at March 31, 2017 and December 31, 2016 : (In Thousands) March 31, 2017 December 31, 2016 Commitments to extend credit $ 270,275 $ 263,487 Standby letters of credit 7,311 6,515 Credit exposure from the sale of assets with recourse 6,463 6,341 $ 284,049 $ 276,343 Commitments to extend credit are legally binding agreements to lend to customers. Commitments generally have fixed expiration dates or other termination clauses and may require payment of fees. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company, on an extension of credit is based on management’s credit assessment of the counterparty. Standby letters of credit represent conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These instruments are issued primarily to support bid or performance related contracts. The coverage period for these instruments is typically a one year period with an annual renewal option subject to prior approval by management. Fees earned from the issuance of these letters are recognized upon expiration of the coverage period. For secured letters of credit, the collateral is typically Bank deposit instruments or customer business assets.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The following disclosures show the hierarchal disclosure framework associated with the level of pricing observations utilized in measuring assets and liabilities at fair value. Level I: Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Level II: Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these assets and liabilities include items for which quoted prices are available but traded less frequently, and items that are fair valued using other financial instruments, the parameters of which can be directly observed. Level III: Assets and liabilities that have little to no pricing observability as of the reported date. These items do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. This hierarchy requires the use of observable market data when available. The following table presents the assets reported on the Consolidated Balance Sheet at their fair value on a recurring basis as of March 31, 2017 and December 31, 2016 , by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. March 31, 2017 (In Thousands) Level I Level II Level III Total Assets measured on a recurring basis: Investment securities, available for sale: Mortgage-backed securities $ — $ 5,072 $ — $ 5,072 Asset-backed securities — 56 — 56 State and political securities — 65,330 — 65,330 Other debt securities — 55,303 — 55,303 Financial institution equity securities 9,898 — — 9,898 Non-financial institution equity securities 1,251 — — 1,251 December 31, 2016 (In Thousands) Level I Level II Level III Total Assets measured on a recurring basis: Investment securities, available for sale: Mortgage-backed securities $ — $ 9,313 $ — $ 9,313 Asset-backed securities — 109 — 109 State and political securities — 60,934 — 60,934 Other debt securities — 51,118 — 51,118 Financial institution equity securities 10,535 — — 10,535 Non-financial institution equity securities 1,483 — — 1,483 The following table presents the assets reported on the Consolidated Balance Sheet at their fair value on a non-recurring basis as of March 31, 2017 and December 31, 2016 , by level within the fair value hierarchy.

The discounted cash flow valuation technique is utilized to determine the fair value of performing impaired loans, while non-performing impaired loans utilize the appraisal of collateral method. The significant unobservable inputs used in the fair value measurement of the Company’s impaired loans using the discounted cash flow valuation technique include temporary changes in payment amounts and the probability of default. Significant increases (decreases) in payment amounts would result in significantly higher (lower) fair value measurements. The probability of default is 0% for impaired loans using the discounted cash flow valuation technique because all defaulted impaired loans are valued using the appraisal of collateral valuation technique. The significant unobservable input used in the fair value measurement of the Company’s impaired loans using the appraisal of collateral valuation technique include appraisal adjustments, which are adjustments to appraisals by management for qualitative factors such as economic conditions and estimated liquidation expenses. The significant unobservable input used in the fair value measurement of the Company’s other real estate owned are the same inputs used to value impaired loans using the appraisal of collateral valuation technique.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company is required to disclose fair values for its financial instruments. Fair values are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Also, it is the Company’s general practice and intention to hold most of its financial instruments to maturity and not to engage in trading or sales activities. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These fair values are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions can significantly affect the fair values. Fair values have been determined by the Company using historical data and an estimation methodology suitable for each category of financial instruments. The Company’s fair values, methods, and assumptions are set forth below for the Company’s other financial instruments. As certain assets and liabilities, such as deferred tax assets, premises and equipment, and many other operational elements of the Company, are not considered financial instruments but have value, this fair value of financial instruments would not represent the full market value of the Company. The fair values of the Company’s financial instruments are as follows at March 31, 2017 and December 31, 2016 : Carrying Fair Fair Value Measurements at March 31, 2017 (In Thousands) Value Value Level I Level II Level III Financial assets: Cash and cash equivalents $ 75,660 $ 75,660 $ 75,660 $ — $ — Investment securities: Available for sale 136,910 136,910 11,149 125,761 — Trading — — — — — Loans held for sale 1,221 1,221 1,221 — — Loans, net 1,098,195 1,119,546 — — 1,119,546 Bank-owned life insurance 27,521 27,521 27,521 — — Accrued interest receivable 3,945 3,945 3,945 — — Financial liabilities: Interest-bearing deposits $ 848,272 $ 845,173 $ 641,024 $ — $ 204,149 Noninterest-bearing deposits 312,392 312,392 312,392 — — Short-term borrowings 8,589 8,589 8,589 — — Long-term borrowings 75,998 76,172 — — 76,172 Accrued interest payable 387 387 387 — — Carrying Fair Fair Value Measurements at December 31, 2016 (In Thousands) Value Value Level I Level II Level III Financial assets: Cash and cash equivalents $ 43,671 $ 43,671 $ 43,671 $ — $ — Investment securities: Available for sale 133,492 133,492 12,018 121,474 — Trading 58 58 58 — — Loans held for sale 1,953 1,953 1,953 — — Loans, net 1,080,785 1,088,122 — — 1,088,122 Bank-owned life insurance 27,332 27,332 27,332 — — Accrued interest receivable 3,672 3,672 3,672 — — Financial liabilities: Interest-bearing deposits $ 791,937 $ 789,401 $ 571,768 $ — $ 217,633 Noninterest-bearing deposits 303,277 303,277 303,277 — — Short-term borrowings 13,241 13,241 13,241 — — Long-term borrowings 85,998 86,353 — — 86,353 Accrued interest payable 455 455 455 — — Cash and Cash Equivalents, Loans Held for Sale, Accrued Interest Receivable, Short-term Borrowings, and Accrued Interest Payable: The fair value is equal to the carrying value. Investment Securities: The fair value of investment securities available for sale and trading is equal to the available quoted market price. If no quoted market price is available, fair value is estimated using the quoted market price for similar securities. Regulatory stocks’ fair value is equal to the carrying value. Loans: Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, financial, and agricultural, commercial real estate, residential real estate, construction real estate, and installment loans to individuals. Each loan category is further segmented into fixed and adjustable rate interest terms and by performing and nonperforming categories. The fair value of performing loans is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan. The estimate of maturity is based on the Company’s historical experience with repayments for each loan classification, modified, as required, by an estimate of the effect of current economic and lending conditions. Fair value for significant nonperforming loans is based on recent external appraisals. If appraisals are not available, estimated cash flows are discounted using a rate commensurate with the risk associated with the estimated cash flows. Assumptions regarding credit risk, cash flows, and discounted rates are judgmentally determined using available market information and specific borrower information. Bank-Owned Life Insurance: The fair value is equal to the cash surrender value of the life insurance policies. Deposits: The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, savings, NOW, and money market accounts, is equal to the amount payable on demand. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The fair value estimates above do not include the benefit that results from the low-cost funding provided by the deposit liabilities compared to the cost of borrowing funds in the market, commonly referred to as the core deposit intangible. Long Term Borrowings: The fair value of long term borrowings is based on the discounted value of contractual cash flows. Commitments to Extend Credit, Standby Letters of Credit, and Financial Guarantees Written: There is no material difference between the notional amount and the estimated fair value of off-balance sheet items. The contractual amounts of unfunded commitments and letters of credit are presented in Note 9 (Off Balance Sheet Risk).

Stock Options	Stock Options In 2014, the Company adopted the 2014 Equity Incentive Plan designed to help the Company attract, retain, and motivate employees and non-employee directors. Incentive stock options, non-qualified stock options, and restricted stock may be granted as part of the plan. On August 27, 2015, the Company issued 38,750 stock options with a strike price of $42.03 to employees that have a five year vesting period and expire ten years from the grant date. On March 24, 2017 , the Company issued 70,000 stock options in total, to a group of employees, that have a strike price of $44.21 . The options granted in 2017 all expire ten years from the grant date however, of the 70,000 grants awarded, 46,250 of the options have a three year vesting period while the remaining 23,750 options vest in five years.

The Company determines the fair value of options granted using the Black-Scholes option-pricing model. The risk-free interest rate is based on the United States Treasury bond with a similar term to the expected life of the options at the grant date. Expected volatility was estimated based on the adjusted historic volatility of the Company’s shares. The expected life was estimated to equal the contractual life of the options. The dividend yield rate was based upon recent historical dividends paid on shares.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (a new revenue recognition standard). The core principle of the update is that a company will recognize revenue to depict the transfer of 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 addition, this update specifies the accounting for certain costs to obtain or fulfill a contract with a customer and expands disclosure requirements for revenue recognition. This update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the impact the adoption of the standard will have on the Company's financial position or results of operation. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This update applies to all entities that hold financial assets or owe financial liabilities and is intended to provide more useful information on the recognition, measurement, presentation, and disclosure of financial instruments. Among other things, this update (a) requires 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; (b) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (c) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; (d) eliminates 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; (e) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (f) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; (g) requires 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 (h) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. For all other entities including not-for-profit entities and employee benefit plans within the scope of Topics 960 through 965 on plan accounting, the amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. All entities that are not public business entities may adopt the amendments in this update earlier as of the fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . The standard requires lessees to recognize the assets and liabilities that arise from leases on the balance sheet. A lessee should recognize in the statement of financial position 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. A short-term lease is defined as one in which: (a) the lease term is 12 months or less, and (b) there is not an option to purchase the underlying asset that the lessee is reasonably certain to exercise. For short-term leases, lessees may elect to recognize lease payments over the lease term on a straight-line basis. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, and interim periods within those years. For all other entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, and for interim periods within fiscal years beginning after December 15, 2020. The amendments should be applied at the beginning of the earliest period presented using a modified retrospective approach with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is currently assessing the practical expedients it may elect at adoption, but does not anticipate the amendments will have a significant impact on the financial statements. Based on the Company's preliminary analysis of its current portfolio, the impact to the Company's balance sheet is estimated to result in less than a 1 percent increase in assets and liabilities. The Company also anticipates additional disclosures to be provided at adoption, or this update is not expected to have a significant impact on the Company's financial statements. In March 2016, the FASB issued ASU 2016-04, Liabilities - Extinguishments of Liabilities (Subtopic 405-20). The standard provides that liabilities related to the sale of prepaid stored-value products within the scope of this Update are financial liabilities. The amendments in the Update provide a narrow scope exception to the guidance in Subtopic 405-20 to require that breakage for those liabilities be accounted for consistent with the breakage guidance in Topic 606. The amendments in this update are effective for public business entities, certain not-for-profit entities, and certain employee benefit plans for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For all other entities, the amendments are effective for financial statements issued for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Earlier application is permitted, including adoption in an interim period. This update is not expected to have a significant impact on the Company’s financial statements. In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815) . The amendments in this update apply to all reporting entities for which there is a change in the counterparty to a derivative instrument that has been designated as a hedging instrument under Topic 815 . The standards in this Update clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815 does not, in and of itself, require designation of that hedging relationship provided that all other hedge accounting criteria continue to be met. For public business entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. For all other entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within fiscal years beginning after December 15, 2018. An entity has an option to apply the amendments in this Update on either a prospective basis or a modified retrospective basis. Early adoption is permitted, including adoption in an interim period. This Update is not expected to have a significant impact on the Company’s financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets. This ASU is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The underlying premise of the ASU is that financial assets measured at amortized cost should be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The allowance for credit losses should reflect management’s current estimate of credit losses that are expected to occur over the remaining life of a financial asset. The income statement will be effected for the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted for annual and interim periods beginning after December 15, 2018. With certain exceptions, transition to the new requirements will be through a cumulative effect adjustment to opening retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which addresses eight specific cash flow issues with the objective of reducing diversity in practice. Among these include recognizing cash payments for debt prepayment or debt extinguishment as cash outflows for financing activities; cash proceeds received from the settlement of insurance claims should be classified on the basis of the related insurance coverage; and cash proceeds received from the settlement of bank-owned life insurance policies should be classified as cash inflows from investing activities while the cash payments for premiums on bank-owned policies may be classified as cash outflows for investing activities, operating activities, or a combination of investing and operating activities. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The amendments in this Update should be applied using a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s statement of cash flows. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740) , which requires recognition of current and deferred income taxes resulting from an intra-entity transfer of any asset (excluding inventory) when the transfer occurs. Consequently, the amendments in this Update eliminate the exception for an intra-entity transfer of an asset other than inventory. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those annual reporting periods. For all other entities, the amendments are effective for annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual periods beginning after December 15, 2019. Early adoption is permitted for all entities as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. That is, earlier adoption should be in the first interim period if an entity issues interim financial statements. The amendments in this Update should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. This Update is not expected to have a significant impact on the Company’s financial statements. In October 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) , which requires that a statement of cash flows explains the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s statement of cash flows. In December 2016, the FASB issued ASU 2016-20 , Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers . This Update, among others things, clarifies that guarantee fees within the scope of Topic 460, Guarantees , (other than product or service warranties) are not within the scope of Topic 606. The effective date and transition requirements for ASU 2016-20 are the same as the effective date and transition requirements for the new revenue recognition guidance. For public entities with a calendar year-end, the new guidance is effective in the quarter and year beginning January 1, 2018. For all other entities with a calendar year-end, the new guidance is effective in the year ending December 31, 2019, and interim periods in 2020. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business , which provides a more robust framework to use in determining when a set of assets and activities (collectively referred to as a “set”) is a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. Public business entities should apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods within those periods. All other entities should apply the amendments to annual periods beginning after December 15, 2018, and interim periods within annual periods beginning after December 15, 2019. The amendments in this Update should be applied prospectively on or after the effective date. This Update is not expected to have a significant impact on the Company’s financial statements. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment . To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this Update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting units fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. A public business entity that is a U.S. Securities and Exchange Commission (“SEC”) filer should adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. A public business entity that is not an SEC filer should adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2020. All other entities, including not-for-profit entities, that are adopting the amendments in this Update should do so for their annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2021. In February 2017, the FASB issued ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) . The amendments in this Update clarify what constitutes a financial asset within the scope of Subtopic 610-20. The amendments also clarify that entities should identify each distinct nonfinancial asset or in substance nonfinancial asset that is promised to a counterparty and to derecognize each asset when the counterparty obtains control. There is also additional guidance provided for partial sales of a nonfinancial asset and when derecognition, and the related gain or loss, should be recognized. The amendments in this Update are effective at the same time as the amendments in Update 2014-09. Therefore, for public entities, the amendments are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. For all other entities, the amendments in this Update are effective for annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. In February 2017, the FASB issued ASU 2017-06 , Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), and Health and Welfare Benefit Plans (Topic 965) . This Update relates primarily to the reporting by an employee benefit plan for its interest in a master trust, which is a trust for which a regulated financial institution serves as a trustee or custodian and in which assets of more than one plan sponsored by a single employer or by a group of employers under common control are held. For each master trust in which a plan holds an interest, the amendments in this Update require a plan's interest in that master trust and any change in that interest to be presented in separate line items in the statement of net assets available for benefits and in the statement of changes in net assets available for benefits, respectively. The amendments in this Update remove the requirement to disclose the percentage interest in the master trust for plans with divided interests and require that all plans disclose the dollar amount of their interest in each of those general types of investments, which supplements the existing requirement to disclose the master trusts balances in each general type of investments. There are also increased disclosure requirements for investments in master trusts. The amendments in this Update are effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20). The amendments in this Update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. 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 adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosures about a change in accounting principle. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.
