It eliminates Step 2 of the current two-step goodwill impairment test, under which a goodwill impairment loss is measured by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill.

Recently Adopted Accounting Guidance

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. The objective of this ASU is to remove inconsistent practices with regard to revenue recognition in and between US GAAP and International Financial Reporting Standards. ASU 2014-09 intends to improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. The adoption of this ASU on November 1, 2018 resulted in a cumulative effect adjustment that increased Accumulated deficit by $6.7 million.
