Accounting Changes and Error Corrections [Abstract]
New Authoritative Accounting Guidance	New Authoritative Accounting Guidance Accounting Standards Update (ASU) No. 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" clarifies on how certain cash receipts and cash payments should be classified and presented in the statement of cash flow. The ASU No. 2016-15 includes guidance on eight cash flow classification issues. ASU No. 2016-15 is effective for fiscal years beginning after December 15, 2017 and is not expected to have a significant impact on Valley's consolidated financial statements. ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" amends the accounting guidance on the impairment of financial instruments. The ASU No. 2016-13 adds to U.S. GAAP an impairment model (known as the current expected credit loss (CECL) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity is required to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. ASU No. 2016-13 is effective for Valley for reporting periods beginning January 1, 2020. Management is currently evaluating the impact of the ASU No. 2016-13 on Valley’s consolidated financial statements. ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" simplifies several aspects of the stock compensation guidance in Topic 718 and other related guidance. The amendments focus on income tax accounting upon vesting or exercise of share-based payments, award classification, liability classification exception for statutory tax withholding requirements, estimating forfeitures, and cash flow presentation. ASU No. 2016-09 is effective for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018 with an early adoption permitted. ASU No. 2016-09 is not expected to have a significant impact on Valley's consolidated financial statements. ASU No. 2016-02, “Leases (Topic 842)” requires the recognition of a right of use asset and related lease liability by lessees for leases classified as operating leases under current GAAP. Topic 842, which replaces the current guidance under Topic 840, retains a distinction between finance leases and operating leases. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee also will not significantly change from current GAAP. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize right of use assets and lease liabilities. Topic 842 will be effective for Valley for reporting periods beginning January 1, 2019, with an early adoption permitted. Valley must apply a modified retrospective transition approach for the applicable leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Management is currently evaluating the impact of Topic 842 on Valley’s consolidated financial statements. ASU No. 2016-01, “Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities” requires that: (i) equity investments with readily determinable fair values must be measured at fair value with changes in fair value recognized in net income, (2) equity investments without readily determinable fair values must be measured at either fair value or at cost adjusted for changes in observable prices minus impairment. Changes in value under either of these methods would be recognized in net income, (3) entities that record financial liabilities at fair value due to a fair value option election must recognize changes in fair value in other comprehensive income if it is related to instrument-specific credit risk, and (4) entities must assess whether a valuation allowance is required for deferred tax assets related to available-for-sale debt securities. ASU No. 2016-01 is effective for Valley for reporting periods beginning January 1, 2018 and is not expected to have a material effect 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 began effective for Valley for reporting periods after January 1, 2016 and did not have an impact on Valley's fair value measurement disclosures at Note 6. ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)" implements a common revenue standard that clarifies the principles for recognizing 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. In 2016, the Financial Accounting Standards Board issued ASU No. 2016-08, “Revenue from Contracts with Customers (Topic 606) - Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” and ASU No. 2016-10, “Revenue from Contracts with Customers (Topic 606) - Identifying Performance Obligations and Licensing,” to further clarify the new guidance under Topic 606. ASU No. 2014-09 and its aforementioned amendments are effective on January 1, 2018. Management is currently evaluating the new revenue guidance but does not expect it to have a significant impact on Valley’s consolidated financial statements.
