New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Accounting Standard Updates (ASU)	Accounting Standard Updates (“ASU”) There have been no accounting standard updates or changes in the status of their adoption that are applicable to the Corporation as previously disclosed in Note 1 of the Corporation's Annual Report on Form 10-K for the year ended June 30, 2016, except the adoption of ASU 2015-05, ASU 2015-10 and ASU 2015-12 beginning in fiscal 2017 which did not have a material impact on its condensed consolidated financial statements and as set forth below. ASU 2017-07: In March 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-07, "Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost." This ASU requires an employer to 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 as defined in paragraphs 715-30-35-4 and 715-60-35-9 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 in this ASU is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The Corporation's adoption of this ASU is not expected to have a material impact on its condensed consolidated financial statements. ASU 2017-03: In January 2017, the FASB issued ASU 2017-03, "Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method and Joint Ventures (Topic 323) and Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings." The SEC staff announcement provided the view that a registrant should evaluate ASUs that have not yet been adopted to determine the appropriate financial statement disclosures about the potential material effects of those ASUs on the financial statements when adopted. This announcement applies to Accounting Standards Update (ASU) No. 2014-09, "Revenue from Contracts with Customers (Topic 606)"; ASU No. 2016-02, "Leases (Topic 842)"; and ASU No. 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The amendments in this ASU is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. The Corporation has adopted the amendments in this ASU and appropriate disclosures have been included in this Note for each recently issued accounting standard. ASU 2016-19: In December 2016, the FASB issued ASU 2016-19, "Technical Corrections and Improvements." The amendments in this ASU cover a wide range of topics in the Codification. The reason is provided before each amendment for clarity and ease of understanding. The amendments in this ASU are generally related to: (1) differences between original guidance and the codification, (2) guidance clarification and reference corrections, (3) simplification and (4) minor improvements. These amendments improve the guidance and are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments in this ASU are effective upon issuance and the Corporation's adoption of this ASU did not have a material impact on its condensed consolidated financial statements. ASU 2016-13: In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." This ASU requires organizations to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This ASU will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Corporation is in the process of identifying required changes to the loan loss estimation models and processes and evaluating the impact of this new guidance. Upon adoption, the Corporation expects the allowance for loan losses to increase, however, until the evaluation is complete the magnitude of the increase will be unknown. ASU 2016-02: In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." This ASU introduces a lessee model that brings most leases on the balance sheet and aligns many of the underlying principles of the new lessor model with those in the new revenue recognition standard, ASC 606, Revenue From Contracts With Customers. The new leases standard represents a wholesale change to lease accounting and will most likely result in significant implementation challenges during the transition period and beyond. This ASU will be effective for annual periods beginning after December 15, 2018, and interim periods therein, early adoption is permitted. The Corporation is currently evaluating the provisions of ASU No. 2016-02 to determine the potential impact the new standard will have on the Company's Consolidated Financial Statements. The Corporation leases buildings and offices under non-cancelable operating leases, the majority of which will be subject to this ASU. While the Corporation has not quantified the impact to its balance sheet, upon adoption of this ASU, the Corporation expects to report increased assets and increased liabilities on its Consolidated Statements of Financial Condition as a result of recognizing right-of-use assets and lease liabilities related to these leases and certain equipment under non-cancelable operating lease agreements, which currently are not reflected in its Consolidated Statements of Financial Condition. ASU 2015-14: In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606)," which defers the effective date of ASU No. 2014-09 one year. ASU No. 2014-09 created Topic 606 and supersedes Topic 605, Revenue Recognition. The core principle of Topic 606 is that an entity recognizes 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 general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. ASU No. 2015-14 is effective for public entities for interim and annual periods beginning after December 15, 2017; early adoption is permitted for interim and annual periods beginning after December 15, 2016. For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. A significant amount of the Corporation's revenues are derived from net interest income on financial assets and liabilities, which are excluded from the scope of the amended guidance. With respect to noninterest income, the Corporation is in its preliminary stages of identifying and evaluating the revenue streams and underlying revenue contracts within the scope of the guidance. The Corporation is expecting to begin developing processes and procedures during 2017 to ensure it is fully compliant with these amendments. To date, the Corporation has not yet identified any significant changes in the timing of revenue recognition when considering the amended accounting guidance; however, the Corporation's implementation efforts are ongoing and such assessments may change prior to the July 1, 2018 implementation date.
