NOTE 8 - REVENUE


We adopted ASU 2014-09 and all subsequent amendments, which are collectively codified in ASC Topic 606 - “Revenue from Contracts with Customers” (“Topic 606”), on November 1, 2018, under the modified retrospective transition method, only with respect to contracts that were not complete as of the date of adoption. This approach required prospective application of the guidance with a cumulative effect adjustment to retained earnings to reflect the impact of the adoption on contracts that were not complete as of the date of the adoption. Please refer to Note 1 for information on our revenue recognition policies.
