Accounting Changes and Error Corrections [Abstract]
New Authoritative Accounting Guidance	New Authoritative Accounting Guidance Accounting Standards Update (ASU) No. 2015-12, "Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965): (Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient" simplifies accounting for employee benefit plans as follows: (i) fully benefit-responsive investment contracts are now to be measured, presented and disclosed at contract value, (ii) the requirement to disclose investments that represent 5 percent or more of net assets available for benefits has been eliminated, (iii) the net appreciation or depreciation in investments for the period should be presented in the aggregate, but is no longer required to be disaggregated and disclosed by general type, (iv) if an investment is measured using the net asset value per share (or its equivalent) practical expedient in Topic 820, and that investment is in a fund that files a U.S. Department of Labor Form 5500, Annual Return/Report of Employee Benefit Plan, as a direct filing entity, disclosure of that investment’s strategy is no longer required, and (v) allows employers to measure (as a practical expedient) benefit plan assets on a month-end date nearest to the employer’s fiscal year end when the fiscal period does not coincide with a month end. ASU No. 2015-12 will be effective for fiscal years beginning after December 15, 2015 and is not expected to have a significant impact on Valley's consolidated financial statements. ASU No. 2015-07, "Fair Value Measurement (Topic 820) - Disclosure for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)", which removes the requirement to categorize within the fair value hierarchy all investments for which the fair value is measured using the net asset value per share practical expedient. ASU No. 2015-07 also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. ASU No. 2015-07 will be effective for Valley for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years with early adoption permitted. Management is currently evaluating the impact of adopting this new ASU on Valley's consolidated financial statements. ASU No. 2015-03, "Interest—Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs" requires 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 ASU No. 2015-03. ASU No. 2015-03 will become effective for Valley for reporting periods (including interim periods) beginning after December 15, 2015 and is not expected to have a significant impact on Valley's consolidated financial statements. ASU No. 2014-14, "Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure" 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. ASU No. 2014-14 became effective for Valley on January 1, 2015 and did not have a significant impact on its consolidated financial statements. 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" requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU No. 2014-12 became effective for Valley on January 1, 2015 and did not have a significant impact on its consolidated financial statements. ASU No. 2014-11, "Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures" requires entities to account for repurchase-to-maturity transactions as secured borrowings rather than as sales with forward repurchase agreements and expands disclosure requirements related to certain transfers of financial assets that are accounted for as sales and certain transfers (specifically, repos, securities lending transactions, and repurchase-to-maturity transactions) accounted for as secured borrowings. The accounting-related changes became effective for the first interim or annual period beginning after December 15, 2014. The disclosures for certain transactions accounted for as sales are required for interim and annual periods beginning after December 15, 2014. The disclosures for repos, securities lending transactions, and repos-to-maturity accounted for as secured borrowings are required for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Valley's repurchase agreements are typical in nature (i.e., not repurchase-to-maturity transactions or repurchase agreements executed as a repurchase financing) and are accounted for as secured borrowings. As such, Valley's adoption of ASU No. 2014-11 on January 1, 2015 did not have a significant impact on its consolidated financial statements. ASU No. 2014-04, “Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure,” clarifies that an in-substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure, or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, this ASU requires interim and annual disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU No. 2014-04 became effective for Valley on January 1, 2015 and did not to have a significant impact on its consolidated financial statements. See Note 8 for related disclosures. ASU No. 2014-01, “Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects,” amends existing guidance to permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense or benefit. For those investments in qualified affordable housing projects not accounted for using the proportional amortization method, the investment should be accounted for as an equity method investment or a cost method investment in accordance with Subtopic 970-323. ASU No. 2014-01 became effective for Valley on January 1, 2015 and did not have a significant impact on its consolidated financial statements. See Note 15 for related disclosures.
