New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Presentation of Financial Statements	Presentation of Financial Statements In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-15, Presentation of Financial Statements – Going Concern. ASU 2014-15 requires management to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern, and if so, disclose that fact. ASU 2014-15 defines substantial doubt as when it is probable that the entity will be unable to meet its obligations as they become due within one year of the date the financial statements are issued. The guidance states that when making this assessment, management should consider relevant conditions or events that are known or reasonably knowable on the date the financial statements are issued. The requirements of ASU 2014-15 are effective for reporting periods beginning after December 15, 2016, with early adoption permitted. The adoption of this update is not expected to have an effect on the financial statements, results of operations or liquidity of the Corporation.
Troubled Debt Restructurings	Troubled Debt Restructurings In August 2014, the FASB issued ASU No. 2014-14, Receivables – Troubled Debt Restructurings by Creditors. ASU 2014-14 requires that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure; (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. An entity can adopt the amendments in this guidance using either a prospective transition method or a modified retrospective method. For prospective transition, an entity should apply the amendments in this update to foreclosures that occur after the date of adoption. For modified retrospective transition, an entity should apply the amendments in this update by means of a cumulative-effect adjustment as of the beginning of the annual period of adoption. Prior periods should not be adjusted. The requirements of ASU 2014-14 are effective for reporting periods beginning after December 15, 2014, with early adoption permitted. The adoption of this update is not expected to have a material effect on the financial statements, results of operations or liquidity of the Corporation. In January 2014, the FASB issued ASU No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure, to clarify when an in-substance repossession or foreclosure occurs; that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and other real estate owned (OREO) recognized. ASU 2014-04 requires a creditor to reclassify a collateralized consumer mortgage loan to OREO upon obtaining legal title to the real estate collateral, or the borrower voluntarily conveying all interest in the real estate property to the lender to satisfy the loan through a deed in lieu of foreclosure or similar legal agreement. The requirements of ASU 2014-04 are effective for reporting periods beginning after December 15, 2014. The adoption of this update will not have an impact on the financial statements, results of operations or liquidity of the Corporation since the Corporation already accounts for foreclosures according to the requirements of this update.
Stock Compensation	Stock Compensation In June 2014, the FASB issued ASU No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. ASU 2014-12 provides guidance relating to the accounting for a performance target that could be achieved after the requisite service period. ASU 2014-12 requires that such performance targets be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. The requirements of ASU 2014-12 are effective for reporting periods beginning after December 15, 2015, with early adoption permitted. Companies may apply the amendments in this standard either prospectively to all awards granted or modified after the effective date or 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 ASU 2014-12 should be recognized as an adjustment to the beginning balance of retained earnings. The adoption of this update is not expected to have a material effect on the financial statements, results of operations or liquidity of the Corporation.
Repurchase Agreements	Repurchase Agreements In June 2014, the FASB issued ASU No. 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures, that requires repurchase-to-maturity transactions to be accounted for as secured borrowings, eliminates current guidance on repurchase financings and requires separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty. ASU 2014-11 also requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements and to disclose information about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The accounting changes in ASU 2014-11 are effective for the first interim or annual reporting period beginning after December 15, 2014. Changes in accounting for transactions outstanding on the effective date must be presented as a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. Early adoption is prohibited. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual reporting periods beginning after December 15, 2014. The disclosure for repurchase agreements 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 Corporation is evaluating this new guidance and has not yet determined the impact that the adoption of this update will have on its financial statements.
Revenue Recognition	Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, to clarify the principles for recognizing revenue and to improve financial reporting by creating common revenue recognition guidance for GAAP and International Financial Reporting Standards. The core principle of the new guidance 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 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. An entity should apply the amendments in this update using either a full retrospective application or a modified retrospective application. Under the full retrospective application, an entity will apply the standard to each prior reporting period presented. Under the modified retrospective application, an entity recognizes the cumulative effect of initially applying the new standard as an adjustment to the opening balance of retained earnings at the date of initial application. Revenue in periods presented before that date will continue to be reported under guidance in effect before the change. The Corporation is evaluating this new guidance and has not yet determined which approach it will adopt to apply the amendments in ASU 2014-09 or the impact that the adoption of this update will have on its financial statements.
Investments in Qualified Affordable Housing Projects	Investments in Qualified Affordable Housing Projects In January 2014, the FASB issued ASU No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects, to revise the accounting for investments in qualified affordable housing projects. ASU 2014-01 modifies the conditions that must be met to present the pretax effects and related tax benefits of such investments as a component of income taxes (“net” within income tax expense). It is expected that the new guidance will enable more investors to use a “net” presentation for investments in qualified affordable housing projects. Investors that do not qualify for “net” presentation under the new guidance will continue to account for such investments under the equity method or cost method, which results in losses recognized in pretax income and tax benefits recognized in income taxes (“gross” presentation of investment results). For investments that qualify for the “net” presentation of investment performance, the guidance introduces a “proportional amortization method” that can be elected to amortize the investment basis. If elected, the method is required for all eligible investments in qualified affordable housing projects. The requirements of ASU 2014-01 are effective for reporting periods beginning after December 15, 2014, with early adoption permitted. The adoption of this update is not expected to have a material effect on the financial statements, results of operations or liquidity of the Corporation.
Income Taxes	Income Taxes In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, to provide guidance on the financial statement presentation of certain unrecognized tax benefits. An unrecognized tax benefit or a portion of an unrecognized tax benefit should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward with certain exceptions related to availability. The requirements of ASU 2013-11 are effective prospectively for reporting periods beginning after December 15, 2013, with early adoption permitted. The adoption of this update did not have a material effect on the financial statements, results of operations or liquidity of the Corporation.

Disclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
