Accounting Policies [Abstract]
Use of Estimates	Use of Estimates: To prepare financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in financial statements and the disclosures provided, and future results could differ. The allowance for loan losses, impairment of goodwill, fair values of financial instruments, deferred taxes and pension obligations are particularly subject to change.
Income Taxes	Income Taxes: Income tax expense is based on the effective tax rate expected to be applicable for the entire year. Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized.
Business Combinations	Business Combinations: At the date of acquisition the Company records the assets and liabilities of the acquired companies on the Consolidated Balance Sheet at their estimated fair value. The results of operations for acquired companies are included in the Company’s Consolidated Statements of Income beginning at the acquisition date. Expenses arising from acquisition activities are recorded in the Consolidated Statements of Income during the period incurred.
Reclassifications	Reclassifications: Some items in the prior year financial statements were reclassified to conform to the current presentation.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities: The Company enters into interest rate swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. All derivatives are accounted for in accordance with ASC-815, Derivatives and Hedging. The Company mitigates the risk of entering into these agreements by entering into equal and offsetting swap agreements with highly rated third party financial institutions. The swap agreements are free-standing derivatives and are recorded at fair value in the Company’s consolidated balance sheets. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes because the Company does not currently intend to execute a setoff with its’ counterparties. The master netting arrangements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral, usually in the form of marketable securities, is posted by the counterparty with net liability positions in accordance with contract thresholds.
Adoption of New Accounting Standards	Adoption of New Accounting Standards: In June 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-10, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The amendments in this Update change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. For repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amendments also require enhanced disclosures. The accounting changes in this Update are effective for the first interim or annual period beginning after December 15, 2014. An entity is required to present changes in accounting for transactions outstanding on the effective date as a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual periods beginning after December 15, 2014, and the disclosure for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The disclosures are not required to be presented for comparative periods before the effective date. This Update did not have a significant impact on the Company’s financial statements. Effect of Newly Issued but Not Yet Effective Accounting Standards: In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (a new revenue recognition standard). The Update’s core principle is that a company will recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, this Update specifies the accounting for certain costs to obtain or fulfill a contract with a customer and expands disclosure requirements for revenue recognition. This Update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is evaluating the effect of adopting this new accounting Update on the Company’s financial statements. In June 2014, the FASB issued ASU 2014-12, Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance Target Could Be Achieved After the Requisite Service Period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The amendments in this Update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. Entities may apply the amendments in this Update either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. If retrospective transition is adopted, the cumulative effect of applying this Update as of the beginning of the earliest annual period presented in the financial statements should be recognized as an adjustment to the opening retained earnings balance at that date. Additionally, if retrospective transition is adopted, an entity may use hindsight in measuring and recognizing the compensation cost. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements -Going Concern (Subtopic 205-40). The amendments in this Update provide guidance in accounting principles generally accepted in the United States of America about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this Update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. This Update is not expected to have a significant impact on the Company’s financial statements. In November 2014, the FASB issued ASU 2014-16, Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity (a consensus of the FASB Emerging Issues Task Force).This Update clarifies how current U.S. GAAP should be interpreted in subjectively evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Public business entities are required to implement the new requirements in fiscal years and interim periods within those fiscal years beginning after December 15, 2015. This Update is not expected to have a significant impact on the Company’s financial statements. In November 2014, the FASB issued ASU 2014-17, Business Combinations (Topic 805): Pushdown Accounting. The amendments in this Update apply to the separate financial statements of an acquired entity and its subsidiaries that are a business or nonprofit activity (either public or nonpublic) upon the occurrence of an event in which an acquirer (an individual or an entity) obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control event occurs. If pushdown accounting is not applied in the reporting period in which the change-in-control event occurs, an acquired entity will have the option to elect to apply pushdown accounting in a subsequent reporting period to the acquired entity’s most recent change-in-control event. The amendments in this Update are effective on November 18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. This Update is not expected to have a significant impact on the Company’s financial statements. In January 2015, the FASB issued ASU 2015-01, Income Statement –Extraordinary and Unusual Items, as part of its initiative to reduce complexity in accounting standards. This Update eliminates from GAAP the concept of extraordinary items. The amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. This Update is not expected to have a significant impact on the Company’s financial statements. In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810). The amendments in this Update affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. Specifically, the amendments (1) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; (2) eliminate the presumption that a general partner should consolidate a limited partnership; (3) affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and (4) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The amendments in this Update are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. For all other entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2016, and for interim periods within fiscal years beginning after December 15, 2017. This Update is not expected to have a significant impact on the Company’s financial statements. In April 2015, the FASB issued ASU 2015-03, Interest-Imputation of Interest (Subtopic 835-30), as part of its initiative to reduce complexity in accounting standards. To simplify presentation of debt issuance costs, the amendments in this Update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this Update. For public business entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2015, 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, 2015, and interim periods within fiscal years beginning after December 15, 2016. An entity should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. This Update is not expected to have a significant impact on the Company’s financial statements. In April 2015, the FASB issued ASU 2015-04, Compensation-Retirement Benefits (Topic 715), as part of its initiative to reduce complexity in accounting standards. For an entity with a fiscal year-end that does not coincide with a month-end, the amendments in this Update provide a practical expedient that permits the entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply that practical expedient consistently from year to year. The practical expedient should be applied consistently to all plans if an entity has more than one plan. The amendments in this Update are effective for public business entities for financial statements issued for fiscal years beginning after December 15, 2015, 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, 2016, and interim periods within fiscal years beginning after December 15, 2017. Earlier application is permitted. This Update is not expected to have a significant impact on the Company’s financial statements. In April 2015, the FASB issued ASU 2015-05, Intangible – Goodwill and Other Internal Use Software (Topic 350-40), as part of its initiative to reduce complexity in accounting standards. This guidance will help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. The amendments in this Update provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. For public business entities, the Board decided that the amendments will be effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. For all other entities, the amendments will be effective for annual periods beginning after December 15, 2015, and interim periods in annual periods beginning after December 15, 2016. Early adoption is permitted for all entities. This Update is not expected to have a significant impact on the Company’s financial statements. In April 2015, the FASB issued ASU 2015-06, Earnings Per Share (Topic 260):Effects on Historical Earnings per Unit of Master Limited Partnership Dropdown Transactions. Topic 260, Earnings Per Share, contains guidance that addresses master limited partnerships that originated from Emerging Issues Task Force (EITF) Issue No. 07-4, Application of the Two-Class Method under FASB Statement No. 128 to Master Limited Partnerships. Under Topic 260, master limited partnerships apply the two-class method of calculating earnings per unit because the general partner, limited partners, and incentive distribution rights holders each participate differently in the distribution of available cash in accordance with the contractual rights contained in the partnership agreement. The amendments in this Update specify that for purposes of calculating historical earnings per unit under the two-class method, the earnings (losses) of a transferred business before the date of a dropdown transaction should be allocated entirely to the general partner. In that circumstance, the previously reported earnings per unit of the limited partners (which is typically the earnings per unit measure presented in the financial statements) would not change as a result of the dropdown transaction. Qualitative disclosures about how the rights to the earnings (losses) differ before and after the dropdown transaction occurs for purposes of computing earnings per unit under the two-class method also are required. The amendments in this Update are effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Earlier application is permitted. This Update is not expected to have a significant impact on the Company’s financial statements. In May 2015, the FASB issued ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). The Update applies to reporting entities that elect to measure the fair value of an investment using the net asset value per share (or its equivalent) practical expedient. Under the amendments in this Update, investments for which fair value is measured at net asset value per share (or its equivalent) using the practical expedient should not be categorized in the fair value hierarchy. Removing those investments from the fair value hierarchy not only eliminates the diversity in practice resulting from the way in which investments measured at net asset value per share (or its equivalent) with future redemption dates are classified, but also ensures that all investments categorized in the fair value hierarchy are classified using a consistent approach. Investments that calculate net asset value per share (or its equivalent), but for which the practical expedient is not applied will continue to be included in the fair value hierarchy. A reporting entity should continue to disclose information on investments for which fair value is measured at net asset value (or its equivalent) as a practical expedient to help users understand the nature and risks of the investments and whether the investments, if sold, are probable of being sold at amounts different from net asset value. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. For all other entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. A reporting entity should apply the amendments retrospectively to all periods presented. The retrospective approach requires that an investment for which fair value is measured using the net asset value per share practical expedient be removed from the fair value hierarchy in all periods presented in an entity’s financial statements. Earlier application is permitted. This Update is not expected to have a significant impact on the Company’s financial statements. In May 2015, the FASB issued ASU 2015-08, Business Combinations – Pushdown Accounting – Amendment to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115. This ASU was issued to amend various SEC paragraphs pursuant to the issuance of Staff Accounting Bulletin No. 115. This Update is not expected to have a significant impact on the Company’s financial statements. In May 2015, the FASB issued ASU 2015-09, Financial Services-Insurance (Topic 944) – Disclosure about Short-Duration Contracts. The amendments apply to all insurance entities that issue short-duration contracts as defined in Topic 944, Financial Services-Insurance. The amendments require insurance entities to disclose for annual reporting periods certain information about the liability for unpaid claims and claim adjustment expenses. The amendments also require insurance entities to disclose information about significant changes in methodologies and assumptions used to calculate the liability for unpaid claims and claim adjustment expenses, including reasons for the change and the effects on the financial statements. Additionally, the amendments require insurance entities to disclose for annual and interim reporting periods a roll forward of the liability for unpaid claims and claim adjustment expenses, described in Topic 944. For health insurance claims, the amendments require the disclosure of the total of incurred-but-not-reported liabilities plus expected development on reported claims included in the liability for unpaid claims and claim adjustment expenses. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2015, and interim periods within annual periods beginning after December 15, 2016. For all other entities, the amendments in this Update are effective for annual periods beginning after December 15, 2016, and interim periods within annual periods beginning after December 15, 2017. This Update is not expected to have a significant impact on the Company’s financial statements. In June 2015, the FASB issued ASU 2015-10, Technical Corrections and Improvements. The amendments in this Update represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. Transition guidance varies based on the amendments in this Update. The amendments in this Update that require transition guidance are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. All other amendments will be effective upon the issuance of this Update. This Update is not expected to have a significant impact on the Company’s financial statements.
