In accordance with ASC 350-20, the Company conducts a goodwill impairment test at least annually, or more frequently as events occur or circumstances change that would more-likely-than-not reduce the fair value below its carrying amount. In the second quarter of fiscal year 2020, the onset of the COVID-19 pandemic prompted the Company to assess qualitative and quantitative factors to determine whether it was more-likely-than-not the fair value of the Company was less than the carrying amount.
The Company assessed relevant events and circumstances, including macroeconomic conditions, industry and market considerations, overall financial performance, changes in the composition or carrying amount of assets and liabilities, the market price of the Company's common stock and other relevant facts. The Company performed both a market capitalization approach and a discounted cash flow approach to determine the fair value of the Company. As a result of the analysis, the Company recognized a goodwill impairment charge of $740.6 million for both the three and six months ended March 31, 2020. No goodwill impairment charge was recognized for the three and six months ended March 31, 2019.
