New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers ( Topic 606 ). The amendments in this Update defer the effective date of ASU 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. The Company is evaluating the effect of adopting this new accounting Update. 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 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 (g) 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. 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 heading 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 March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815) . The amendments apply to all entities that are issuers of or investors in debt instruments (or hybrid financial instruments that are determined to have a debt host) with embedded call (put) options. The amendments in this Update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt host. An entity performing the assessment under the amendments in this Update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. 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 entities other than public business 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. 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 March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606). The amendments in this Update affect entities with transactions included within the scope of Topic 606, which includes entities that enter into contracts with customers to transfer goods or services (that are an output of the entity’s ordinary activities) in exchange for consideration. The amendments in this Update do not change the core principle of the guidance in Topic 606; they simply clarify the implementation guidance on principal versus agent considerations. The amendments in this Update are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations. The amendments in this Update affect the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements of Update 2014-09. ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, defers the effective date of Update 2014-09 by one year. 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 April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606). The amendments in this Update affect entities with transactions included within the scope of Topic 606, which includes entities that enter into contracts with customers to transfer goods or services in exchange for consideration. The amendments in this Update do not change the core principle for revenue recognition in Topic 606. Instead, the amendments provide (1) more detailed guidance in a few areas and (2) additional implementation guidance and examples based on feedback the FASB received from its stakeholders. The amendments are expected to reduce the degree of judgment necessary to comply with Topic 606, which the FASB expects will reduce the potential for diversity arising in practice and reduce the cost and complexity of applying the guidance. The amendments in this Update affect the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements in Topic 606 (and any other Topic amended by Update 2014-09). ASU 2015-14, Revenue from Contracts with Customers (Topic 606) : Deferral of the Effective Date , defers the effective date of Update 2014-09 by one year. 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 May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606) , which among other things clarifies the objective of the collectability criterion in Topic 606, as well as certain narrow aspects of Topic 606. The amendments in this Update affect the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by Update 2014-09). ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , defers the effective date of Update 2014-09 by one year. 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 , which changes the impairment model for most financial assets. This Update 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 Update 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. We expect to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, but cannot yet determine the magnitude of any such one-time adjustment or the overall impact of the new guidance on the consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , 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 2016-17, Consolidation (Topic 810) , which amends the consolidation guidance on how a reporting entity that is the single decision maker of a VIE should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The primary beneficiary of a VIE is the reporting entity that has a controlling financial interest in a VIE and, therefore, consolidates the VIE. A reporting entity has an indirect interest in a VIE if it has a direct interest in a related party that, in turn, has a direct interest in the VIE. Under the amendments, a single decision maker is not required to consider indirect interests held through related parties that are under common control with the single decision maker to be the equivalent of direct interests in their entirety. Instead, a single decision maker is required to include those interests on a proportionate basis consistent with indirect interests held through other related parties. 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 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323), Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings . This Update adds an SEC paragraph to the Codification following an SEC Staff Announcement about applying Staff Accounting Bulletin (SAB) Topic 11.M. Specifically, this announcement applies to ASU 2014-09, Revenue from Contracts with Customers (Topic 606); ASU 2016-02, Leases (Topic 842); and ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . A registrant should evaluate Updates that have not yet been adopted to determine the appropriate financial statement disclosures about the potential material effects of those Updates on the financial statements when adopted. If a registrant does not know or cannot reasonably estimate the impact that adoption of the Updates referenced in this announcement are expected to have on the financial statements, then in addition to making a statement to that effect, that registrant should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact that the standard will have on the financial statements of the registrant when adopted. In this regard, the SEC staff expects the additional qualitative disclosures to include a description of the effect of the accounting policies that the registrant expects to apply, if determined, and a comparison to the registrant’s current accounting policies. Also, a registrant should describe the status of its process to implement the new standards and the significant implementation matters yet to be addressed. The amendments in this Update are effective immediately. 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. This Update is not expected to have a significant impact on the Company’s financial statements. 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. This Update is not expected to have a significant impact on the Company’s financial statements. In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715) . The amendments in this Update require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost as defined in paragraphs 715-30-35-4 and 715-60-35-9 are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are used to present the other components of net benefit cost, that line item or items must be appropriately described. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. This Update is not expected to have a significant impact on the Company’s financial statements. 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. This Update is not expected to have a significant impact on the Company’s financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718) , which affects any entity that changes the terms or conditions of a share-based payment award. This Update amends the definition of modification by qualifying that modification accounting does not apply to changes to outstanding share-based payment awards that do not affect the total fair value, vesting requirements, or equity/liability classification of the awards. The amendments in this Update are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for (1) public business entities for reporting periods for which financial statements have not yet been issued and (2) all other entities for reporting periods for which financial statements have not yet been made available for issuance. The amendments in this Update should be applied prospectively to an award modified on or after the adoption date. This Update is not expected to have a significant impact on the Company’s financial statements. In May 2017, the FASB issued ASU 2017-10, Service Concession Arrangements (Topic 853) , which applies to the accounting by operating entities for service concession arrangements within the scope of Topic 853. The amendments in this Update clarify that the grantor (government), rather than the third-party drivers, is the customer of the operation services in all cases for service concession arrangements within the scope of Topic 853. For an entity that has not adopted Topic 606 before the issuance of this Update, the effective date and transition requirements for the amendments in this Update generally are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by ASU 2014-09, Revenue from Contracts with Customers (Topic 606)) . ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , deferred the effective date of Update 2014-09 by one year. This Update is not expected to have a significant impact on the Company’s financial statements. In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivative and Hedging (Topic 815) . The amendments in Part I of this Update change the classification analysis of certain equity-linked financial instruments (or embedded features) with down-round features. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a down-round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. The amendments also clarify existing disclosure requirements for equity-classified instruments. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down-round feature. For freestanding equity classified financial instruments, the amendments require entities that present earnings per share (“EPS”) in accordance with Topic 260 to recognize the effect of the down-round feature when it is triggered. That effect is treated as a dividend and as a reduction of income available to common shareholders in basic EPS. Convertible instruments with embedded conversion options that have down- round features are now subject to the specialized guidance for contingent beneficial conversion features (in Subtopic 470-20, Debt-Debt with Conversion and Other Options ), including related EPS guidance (in Topic 260). The amendments in Part II of this Update recharacterize the indefinite deferral of certain provisions of Topic 480 that now are presented as pending content in the Accounting Standards Codification, to a scope exception. Those amendments do not have an accounting effect. For public business entities, the amendments in Part I o

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 June 30, 2017 . These options were excluded, 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 $43.26 being in excess of the exercise price of the options. There were a total of 31,000 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 $40.06 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.

The Company reviews its position quarterly and has determined that, at June 30, 2017 , the declines outlined in the above table represent temporary declines and the Company does not intend to sell and does not believe it will be required to sell these securities before recovery of their cost basis, which may be at maturity. The Company has concluded that the unrealized losses disclosed above are not other than temporary but are the result of interest rate changes, sector credit ratings changes, or company-specific ratings changes that are not expected to result in the non-collection of principal and interest during the period. The amortized cost and fair value of debt securities at June 30, 2017 , by contractual maturity, are shown below.

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 June 30, 2017 and December 31, 2016 : June 30, 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 $ 147,297 $ 424 $ 9 $ 564 $ 148,294 Real estate mortgage: Residential 566,188 2,509 67 1,932 570,696 Commercial 307,285 632 1,152 8,649 317,718 Construction 33,986 18 101 — 34,105 Installment loans to individuals 68,862 637 — 24 69,523 1,123,618 $ 4,220 $ 1,329 $ 11,169 1,140,336 Net deferred loan fees and discounts (1,251 ) (1,251 ) Allowance for loan losses (13,109 ) (13,109 ) Loans, net $ 1,109,258 $ 1,125,976 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.

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.

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 and six months ended June 30, 2017. Loan modifications that are considered TDRs completed during the three and six months ended June 30, 2016 were as follows.

There were five loan modifications considered TDRs made during the twelve months previous to June 30, 2016 that defaulted during the six months ended June 30, 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 $8,402,000 and $9,180,000 as of June 30, 2017 and December 31, 2016 . The amount of foreclosed residential real estate held at June 30, 2017 and December 31, 2016 , totaled $278,000 and $839,000 , respectively. Consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process at June 30, 2017 and December 31, 2016 , totaled $69,000 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 June 30, 2017 and December 31, 2016 : June 30, 2017 Commercial, Financial, and Agricultural Real Estate Mortgages Installment Loans to Individuals (In Thousands) Residential Commercial Construction Totals Pass $ 143,855 $ 567,603 $ 292,505 $ 33,953 $ 69,523 $ 1,107,439 Special Mention 1,777 1,152 9,404 — — 12,333 Substandard 2,662 1,941 15,809 152 — 20,564 $ 148,294 $ 570,696 $ 317,718 $ 34,105 $ 69,523 $ 1,140,336 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 June 30, 2017 and 2016 : June 30, 2017 2016 Owners of residential rental properties 15.64 % 16.74 % Owners of commercial rental properties 14.56 % 14.14 % 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 June 30, 2017 and December 31, 2016 : June 30, 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 $ 375 $ 243 $ 1,584 $ — $ 17 $ — $ 2,219 Collectively evaluated for impairment 1,356 5,094 2,143 172 762 1,363 10,890 Total ending allowance balance $ 1,731 $ 5,337 $ 3,727 $ 172 $ 779 $ 1,363 $ 13,109 Loans: Individually evaluated for impairment $ 603 $ 3,162 $ 13,635 $ — $ 17 $ 17,417 Collectively evaluated for impairment 147,691 567,534 304,083 34,105 69,506 1,122,919 Total ending loans balance $ 148,294 $ 570,696 $ 317,718 $ 34,105 $ 69,523 $ 1,140,336 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 June 30, 2017 and December 31, 2016 : (In Thousands) June 30, 2017 December 31, 2016 Commitments to extend credit $ 281,335 $ 263,487 Standby letters of credit 10,474 6,515 Credit exposure from the sale of assets with recourse 6,761 6,341 $ 298,570 $ 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 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 June 30, 2017 and December 31, 2016 : Carrying Fair Fair Value Measurements at June 30, 2017 (In Thousands) Value Value Level I Level II Level III Financial assets: Cash and cash equivalents $ 38,202 $ 38,202 $ 38,202 $ — $ — Investment securities: Available for sale 138,504 138,504 11,755 126,749 — Trading 213 213 213 — — Loans held for sale 1,683 1,683 1,683 — — Loans, net 1,125,976 1,169,901 — — 1,169,901 Bank-owned life insurance 27,670 27,670 27,670 — — Accrued interest receivable 3,641 3,641 3,641 — — Financial liabilities: Interest-bearing deposits $ 851,056 $ 856,563 $ 651,773 $ — $ 204,790 Noninterest-bearing deposits 300,054 300,054 300,054 — — Short-term borrowings 15,737 15,737 15,737 — — Long-term borrowings 75,998 76,123 — — 76,123 Accrued interest payable 414 414 414 — — 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).

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
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. Stock Options Granted Date Shares Forfeited Outstanding Strike Price Vesting Period Expiration March 24, 2017 46,250 — 46,250 $ 44.21 3 years 10 years March 24, 2017 23,750 — 23,750 44.21 5 years 10 years August 27, 2015 38,750 (12,250 ) 26,500 42.03 5 years 10 years A summary of stock option activity is presented below: June 30, 2017 June 30, 2016 Shares Weighted Average Exercise Price Shares Weighted Average Exercise Price Outstanding, beginning of year 26,500 $ 42.03 34,750 $ 42.03 Granted 70,000 44.21 — — Exercised — — — — Forfeited — — (3,750 ) 42.03 Expired — — — — Outstanding, end of year 96,500 $ 43.61 31,000 $ 42.03 Exercisable, end of year — $ — — $ — The estimated fair value of options, including the effect of estimated forfeitures, is recognized as expense on a straightline basis over the options’ vesting periods while ensuring that the cumulative amount of compensation cost recognized at least equals the value of the vested portion of the award at that date. 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. Compensation expense for stock options is recognized using the fair value when the stock options are granted and is amortized over the options' vesting period. Compensation expense, with a corresponding increase in contributed surplus, related to stock options was $8,000 and $13,000 for the three and six month periods ended June 30, 2017 compared to $5,000 and $11,000 for the same periods of 2016. As of June 30, 2017, no stock options were exercisable and the weighted average years to expiration were 9.3 years . The fair value of options granted during the three and six month periods ending June 30, 2017 was approximately zero and $1,702,000 respectively or zero and $24.32 per award. Total unrecognized compensation cost for non-vested shares, $116,000 , will be recognized over their weighted average remaining vesting period of 4.7 years .

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers ( Topic 606 ). The amendments in this Update defer the effective date of ASU 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. The Company is evaluating the effect of adopting this new accounting Update. 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 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 (g) 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. 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 heading 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 March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815) . The amendments apply to all entities that are issuers of or investors in debt instruments (or hybrid financial instruments that are determined to have a debt host) with embedded call (put) options. The amendments in this Update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt host. An entity performing the assessment under the amendments in this Update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. 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 entities other than public business 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. 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 March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606). The amendments in this Update affect entities with transactions included within the scope of Topic 606, which includes entities that enter into contracts with customers to transfer goods or services (that are an output of the entity’s ordinary activities) in exchange for consideration. The amendments in this Update do not change the core principle of the guidance in Topic 606; they simply clarify the implementation guidance on principal versus agent considerations. The amendments in this Update are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations. The amendments in this Update affect the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements of Update 2014-09. ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, defers the effective date of Update 2014-09 by one year. 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 April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606). The amendments in this Update affect entities with transactions included within the scope of Topic 606, which includes entities that enter into contracts with customers to transfer goods or services in exchange for consideration. The amendments in this Update do not change the core principle for revenue recognition in Topic 606. Instead, the amendments provide (1) more detailed guidance in a few areas and (2) additional implementation guidance and examples based on feedback the FASB received from its stakeholders. The amendments are expected to reduce the degree of judgment necessary to comply with Topic 606, which the FASB expects will reduce the potential for diversity arising in practice and reduce the cost and complexity of applying the guidance. The amendments in this Update affect the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements in Topic 606 (and any other Topic amended by Update 2014-09). ASU 2015-14, Revenue from Contracts with Customers (Topic 606) : Deferral of the Effective Date , defers the effective date of Update 2014-09 by one year. 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 May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606) , which among other things clarifies the objective of the collectability criterion in Topic 606, as well as certain narrow aspects of Topic 606. The amendments in this Update affect the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by Update 2014-09). ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , defers the effective date of Update 2014-09 by one year. 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 , which changes the impairment model for most financial assets. This Update 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 Update 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. We expect to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, but cannot yet determine the magnitude of any such one-time adjustment or the overall impact of the new guidance on the consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , 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 2016-17, Consolidation (Topic 810) , which amends the consolidation guidance on how a reporting entity that is the single decision maker of a VIE should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The primary beneficiary of a VIE is the reporting entity that has a controlling financial interest in a VIE and, therefore, consolidates the VIE. A reporting entity has an indirect interest in a VIE if it has a direct interest in a related party that, in turn, has a direct interest in the VIE. Under the amendments, a single decision maker is not required to consider indirect interests held through related parties that are under common control with the single decision maker to be the equivalent of direct interests in their entirety. Instead, a single decision maker is required to include those interests on a proportionate basis consistent with indirect interests held through other related parties. 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 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323), Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings . This Update adds an SEC paragraph to the Codification following an SEC Staff Announcement about applying Staff Accounting Bulletin (SAB) Topic 11.M. Specifically, this announcement applies to ASU 2014-09, Revenue from Contracts with Customers (Topic 606); ASU 2016-02, Leases (Topic 842); and ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . A registrant should evaluate Updates that have not yet been adopted to determine the appropriate financial statement disclosures about the potential material effects of those Updates on the financial statements when adopted. If a registrant does not know or cannot reasonably estimate the impact that adoption of the Updates referenced in this announcement are expected to have on the financial statements, then in addition to making a statement to that effect, that registrant should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact that the standard will have on the financial statements of the registrant when adopted. In this regard, the SEC staff expects the additional qualitative disclosures to include a description of the effect of the accounting policies that the registrant expects to apply, if determined, and a comparison to the registrant’s current accounting policies. Also, a registrant should describe the status of its process to implement the new standards and the significant implementation matters yet to be addressed. The amendments in this Update are effective immediately. 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. This Update is not expected to have a significant impact on the Company’s financial statements. 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. This Update is not expected to have a significant impact on the Company’s financial statements. In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715) . The amendments in this Update require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost as defined in paragraphs 715-30-35-4 and 715-60-35-9 are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are used to present the other components of net benefit cost, that line item or items must be appropriately described. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. This Update is not expected to have a significant impact on the Company’s financial statements. 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. This Update is not expected to have a significant impact on the Company’s financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718) , which affects any entity that changes the terms or conditions of a share-based payment award. This Update amends the definition of modification by qualifying that modification accounting does not apply to changes to outstanding share-based payment awards that do not affect the total fair value, vesting requirements, or equity/liability classification of the awards. The amendments in this Update are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for (1) public business entities for reporting periods for which financial statements have not yet been issued and (2) all other entities for reporting periods for which financial statements have not yet been made available for issuance. The amendments in this Update should be applied prospectively to an award modified on or after the adoption date. This Update is not expected to have a significant impact on the Company’s financial statements. In May 2017, the FASB issued ASU 2017-10, Service Concession Arrangements (Topic 853) , which applies to the accounting by operating entities for service concession arrangements within the scope of Topic 853. The amendments in this Update clarify that the grantor (government), rather than the third-party drivers, is the customer of the operation services in all cases for service concession arrangements within the scope of Topic 853. For an entity that has not adopted Topic 606 before the issuance of this Update, the effective date and transition requirements for the amendments in this Update generally are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by ASU 2014-09, Revenue from Contracts with Customers (Topic 606)) . ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , deferred the effective date of Update 2014-09 by one year. This Update is not expected to have a significant impact on the Company’s financial statements. In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivative and Hedging (Topic 815) . The amendments in Part I of this Update change the classification analysis of certain equity-linked financial instruments (or embedded features) with down-round features. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a down-round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. The amendments also clarify existing disclosure requirements for equity-classified instruments. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down-round feature. For freestanding equity classified financial instruments, the amendments require entities that present earnings per share (“EPS”) in accordance with Topic 260 to recognize the effect of the down-round feature when it is triggered. That effect is treated as a dividend and as a reduction of income available to common shareholders in basic EPS. Convertible instruments with embedded conversion options that have down- round features are now subject to the specialized guidance for contingent beneficial conversion features (in Subtopic 470-20, Debt-Debt with Conversion and Other Options ), including related EPS guidance (in Topic 260). The amendments in Part II of this Update recharacterize the indefinite deferral of certain provisions of Topic 480 that now are presented as pending content in the Accounting Standards Codification, to a scope exception. Those amendments do not have an accounting effect. For public business entities, the amendments in Part I of this Update are effective for f
