Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and Other Intangible Assets | Note 7 - Goodwill and Other Intangible Assets A goodwill impairment test is required under ASC 350, Intangibles – Goodwill and Other, and the FASB issued ASU No. 2011-08, “Testing Goodwill for Impairment,” allowing an initial qualitative assessment of goodwill commonly known as step zero impairment testing. In general, the step zero test allows an entity to first assess qualitative factors to determine whether it is more likely than not (i.e., more than 50%) that the fair value of a reporting unit is less than its carrying value. If a step zero impairment test results in the conclusion that it is more likely than not that the fair value of the reporting unit exceeds its carrying value, then no further testing is required. Step zero impairment testing is an assessment of qualitative factors that affect the likelihood of impairment. Based upon management’s review, the Company’s intangible assets were not impaired and there has been no impairment through December 31, 2018. Management concludes that the ASC 350 goodwill step zero test has been passed, and no further testing is required. Goodwill The change in goodwill during the year is as follows:
