Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	GENERAL Financial Statement Preparation The significant accounting policies followed by the Corporation and its wholly-owned subsidiaries for interim financial reporting are consistent with the accounting policies followed for annual financial reporting. All adjustments, which are of a normal recurring nature and are in the opinion of management necessary for a fair statement of the results for the periods reported, have been included in the accompanying Consolidated Condensed Financial Statements. The Consolidated Condensed Balance Sheet of the Corporation as of December 31, 2017, has been derived from the audited consolidated balance sheet of the Corporation as of that date. Certain information and note disclosures normally included in the Corporation’s annual financial statements, prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted. These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2017 filed with the Securities and Exchange Commission. The results of operations for the three and nine months ended September 30, 2018, are not necessarily indicative of the results to be expected for the year. Reclassifications have been made to prior financial statements to conform to the current financial statement presentation. These reclassifications had no effect on net income. Recent Accounting Changes ASU 2018-02 "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ("ASU 2018-02") allows a reclassification from accumulated other comprehensive income (loss) to retained earnings for the stranded tax effects caused by the revaluation of deferred taxes resulting from the newly enacted corporate tax rate in the Tax Cuts and Jobs Act. The ASU is effective in years beginning after December 15, 2018, but permits early adoption in a period for which financial statements have not yet been issued. The Corporation elected to early adopt the ASU as of January 1, 2018. The adoption of the guidance resulted in an insignificant cumulative-effect adjustment that decreased accumulated other comprehensive income (loss) and increased retained earnings in 2018. ASU 2017-12 - "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" ("ASU 2017-12") is intended to improve and simplify accounting rules around hedge accounting. The ASU is effective for public companies in 2019 and private companies in 2020. Early adoption is permitted. The new standard refines and expands hedge accounting for both financial (e.g., interest rate) and commodity risks. Its provisions create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes, for investors and analysts. The new standard takes effect for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, for public companies and for fiscal years beginning after December 15, 2019 (and interim periods for fiscal years beginning after December 15, 2020), for private companies. Early adoption is permitted in any interim period or fiscal years before the effective date of the standard. ASU 2017-12 requires a modified retrospective transition method in which a cumulative effect of the change on the opening balance of each affected component of equity is recognized in the statement of financial position as of the date of adoption. The Corporation adopted this standard in the third quarter of 2018. As permitted by the ASU, the Corporation reclassified $30.8 million of state and municipal securities with unrealized gains of $450,000 from the held to maturity portfolio to the available for sale portfolio. Other than this reclassification of securities, adoption of the standard did not have a significant impact on the Corporation’s consolidated financial statements. ASU 2017-07 "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" ("ASU 2017-07") applies to all employers, including not-for-profit entities, that offer to their employees defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715, Compensation - Retirement Benefits. The amendments 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 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. The amendments also allow only the service cost component to be eligible for capitalization when applicable (e.g., as a cost of internally manufactured inventory or a self-constructed asset). The amendments are effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those annual periods. For other entities, the amendments are effective for annual periods beginning after December 15, 2018, and interim periods within annual periods beginning after December 15, 2019. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The Corporation adopted this ASU in 2018. Adoption of the standard did not have a significant impact on the Corporation’s consolidated financial statements. ASU 2016-15 "Statement of Cash Flows (Topic 230)" ("ASU 2016-15") is intended to reduce the diversity in practice around how certain transactions are classified within the statement of cash flows. ASU 2016-15 became effective for the Corporation on January 1, 2018 and did not have a significant impact on the Corporation's financial statements. ASU 2016-01 "Financial Instruments - Overall (Subtopic 825-10): Recognition of Financial Assets and Financial Liabilities" ("ASU 2016-01") makes targeted amendments to the guidance for recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 requires equity investments, other than equity method investments, to be measured at fair value with changes in fair value recognized in net income. The ASU requires a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption to reclassify the cumulative change in fair value of equity securities previously recognized in accumulated other comprehensive income (loss). ASU 2016-01 became effective for the Corporation on January 1, 2018. The adoption of the guidance did not result in any cumulative effect adjustment in 2018. ASU 2016-01 also emphasizes the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of a practicability exception in determining the fair value of loans. Accordingly, the Corporation refined the calculation used to determine the disclosed fair value of loans held for investment as part of adopting this standard. The refined calculation did not have a significant impact on the fair value disclosures included in NOTE 9. DISCLOSURES ABOUT FAIR VALUE OF ASSETS AND LIABILITIES of these Notes to Consolidated Condensed Financial Statements. ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09") implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 establishes a five-step model which entities must follow to recognize revenue and removes inconsistencies and weaknesses in existing guidance. The guidance does not apply to revenue associated with financial instruments, including loans and investment securities that are accounted for under other GAAP, which comprises a significant portion of our revenue stream. ASU 2014-09 became effective for the Corporation on January 1, 2018. The adoption of ASU 2014-09 did not result in a change to the accounting for any of the in-scope revenue streams; as such, no cumulative effect adjustment was recorded. Additional information related to revenue generated from contracts with customers is detailed below. Revenue Recognition ASU 2014-09 establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. The majority of the Corporation's revenue-generating transactions are not subject to ASU 2014-09, including revenue generated from financial instruments, such as loans, letters of credit, derivatives and investment securities, as well as revenue related to mortgage servicing activities, as these activities are subject to other GAAP discussed elsewhere within the disclosures. The Corporation has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Condensed Statements of Income was not necessary. Descriptions of revenue-generating activities that are within the scope of ASU 2014-09, which are presented in our income statements are as follows: Service charges on deposit accounts: The Corporation earns fees from its deposit customers for transaction-based, account maintenance and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering and ACH fees, are recognized at the time the transaction is executed, which is the point in time the Corporation fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are earned monthly, representing the period which the Corporation satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance. Fiduciary activities: This represents monthly fees due from wealth management customers as consideration for managing the customers' assets. Wealth management and trust services include custody of assets, investment management, fees for trust services and similar fiduciary activities. These fees are primarily earned over time as the Corporation provides the contracted monthly or quarterly services and are generally assessed based on the market value of assets under management at month-end. Fees that are transaction-based are recognized at the point in time that the transaction is executed. Investment Brokerage Fees: The Corporation earns fees from investment brokerage services provided to its customers by a third-party service provider. The Corporation receives commissions from the third-party provider on a monthly basis based upon customer activity for the month. The fees are paid to us by the third party on a monthly basis and are recognized when received. Interchange income: The Corporation earns interchange fees from debit and credit cardholder transactions conducted through the Visa and MasterCard payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized concurrent with the transaction processing services provided to the cardholder. Gains (Losses) on Sales of OREO: The Corporation records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Corporation finances the sale of OREO to the buyer, the Corporation assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Corporation adjusts the transaction price and related gain (loss) on sale if a significant financing component is present.
