In accordance with ASC 805, on March 10, 2020, goodwill was recognized as a result of the Merger and was allocated to the Company’s reporting units on a relative fair value basis. Subsequent to the Merger, we concluded a triggering event had occurred due to the expected impact on our financial results due to COVID-19. Therefore, we performed a goodwill impairment test as of March 31, 2020 to compare each reporting unit’s carrying value to the respective fair value. The fair value of each reporting unit was determined using a combination of an income approach based on a discounted cash flow model and a market approach based on appropriate valuation multiples observed for the reporting unit’s guideline public companies. Fair value estimates resulted from a complex series of judgments about future events and uncertainties and relied heavily on estimates and assumptions. The estimates considered most impactful to the goodwill impairment test included our expectation on the amount of time it will take to return to a normal level of healthcare activity, the discount rate used in the income approach, and the market multiples used in the market approach. Reporting unit fair values were considered a Level 3 measurement due to the significance of unobservable inputs developed using company specific information. Based on the results of the interim impairment test, we recorded a non-cash pre-tax goodwill impairment charge of $561,164 for the year ended March 31, 2020, which was not deductible for income tax purposes.
