ASC 606 implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASC 606 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. To achieve that core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the entity satisfies a performance obligation.

The Corporation adopted ASC 606 on July 1, 2018 using the modified retrospective approach. Therefore, the comparative information has not been adjusted and continues to be reported under superseded ASC 605. There was no cumulative effect adjustment as of July 1, 2018, and there were no material changes to the timing or amount of revenue recognized for the three months ended September 30, 2018; however, additional disclosures were incorporated in the footnotes upon adoption. The majority of the Company's revenue is comprised of interest income from financial assets, which is explicitly excluded from the scope of ASC 606. The Corporation elected to apply the practical expedient pursuant to ASC 606 and therefore does not disclose information about remaining performance obligations that have an original expected term of one year or less and allows the Corporation to expense costs related to obtaining a contract as incurred when the original amortization period would have been one year or less. See Note 12 for additional discussion. ASU 2018-11 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 (i.e., calendar periods beginning on January 1, 2019), and interim periods therein, early adoption is permitted. In July 2018, the FASB issued ASU 2018-11, Leases, Targeted Improvements, which allows entities the option of initially applying the new leases standard at the adoption date (such as January 1, 2019, for calendar year- end public business entities) and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Corporation plans to adopt ASU 2018-11 on July 1, 2019.

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 significant 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, 2018, other than:

ASU 2014-09:

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, "Revenue from Contracts with Customers," which created FASB Accounting Standards Codification (ASC) Topic 606 ("ASC 606"). ASC 606 implements a common revenue standard that clarifies the principles for recognizing revenue.

See Note 12 for additional discussion.

ASU 2018-11

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.

ASU 2018-13

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies disclosure requirements on fair value measurements to improve their effectiveness. The guidance permits entities to consider materiality when evaluating fair value measurement disclosures and, among other modifications, requires certain new disclosures related to Level 3 fair value measurements.
