The Company performs its annual impairment test for goodwill utilizing a combination of discounted cash flow methodology, market comparables and an overall market capitalization reasonableness test in computing fair value by reporting unit. The Company then compares the fair value of the reporting unit with its carrying value to assess if goodwill has been impaired. Based on the assumptions as to growth, discount rates and the weighting used for each respective valuation methodology, results of the valuations could be significantly different. The Company believes that the methodologies and weightings used are reasonable and result in appropriate fair values of the reporting units.

The Company performed its annual impairment test for goodwill as of October 1, 2019 and October 1, 2018 and determined that no adjustment to the carrying value was required.
