NOTE 7—INTANGIBLE ASSETS AND GOODWILL

The Company conducted its annual impairment test of goodwill as of September 30, 2022 and determined that there was no impairment. The Company also tests its intangible assets and goodwill between the annual impairment tests if events occur or circumstances change that would more likely than not reduce the fair value of the Company or its assets below their carrying amounts. For intangible assets subject to amortization, the Company performs its impairment test when indicators, such as reductions in demand or significant economic slowdowns, are present. During the fourth quarter ended December 31, 2022, due to the sustained decrease in the stock price of BIOLASE common stock decreasing the implied fair value of the business, the Company performed a quantitative assessment of impairment over goodwill and determined that there was no impairment to our goodwill. Goodwill was valued using an equally weighted income approach and market approach. The unobservable inputs utilized in determining the fair value of the goodwill, which is categorized as a Level 3 instrument, are the discount rate of 15.7% and various revenue growth rates utilized in the financial forecast of future cash flows.

Due to the further decrease in the stock price of BIOLASE common stock as of March 31, 2023 decreasing the implied fair value of the business, the Company performed an additional quantitative assessment of impairment over goodwill and determined that there was no impairment to our goodwill as of March 31, 2023. Goodwill was valued using an equally weighted income approach and market approach. The unobservable inputs utilized in determining the fair value of the goodwill, which is categorized as a Level 3 instrument, are the discount rate of 25.0% and various revenue growth rates utilized in the financial forecast of future cash flows.
