| Description of recent accounting standards | This standard eliminated Step 2 from the goodwill impairment test. Step 2 required entities to compute the implied fair value of goodwill if it was determined that the carrying amount of a reporting unit exceed its fair value. The goodwill impairment test now consists of comparing the fair value of a reporting unit with its carrying amount, and a company should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. This standard is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. |
