During the three months ended March 31, 2024, we completed our annual assessments for impairment of goodwill and indefinite-lived intangible assets. For our goodwill testing, we performed a qualitative analysis and determined that there was no indication of impairment requiring further quantitative testing. No material impairment losses were recognized in the current or prior periods presented in connection with our goodwill and intangible assets.

At September 30, 2023, we determined that due to the recent decline in the Company’s share price and market capitalization, among other factors, a quantitative assessment was required. Based on our September 30, 2023, quantitative assessment using a discounted cash flow, we estimated the fair value for our Beauty Systems Group (“BSG”) reporting unit to be approximately 18% more than its carrying value. The critical assumptions used as part of our evaluation included a projected long-term revenue growth rate of 2.0% and a discount rate of 11.25%, based on a weighted-average cost of capital analysis (adjusted for company-specific risk). Our September 30, 2023, quantitative assessment indicated that the fair value of our SBS segment was substantially higher than its carrying value. Goodwill allocated to our SBS and BSG reporting units, which are also defined as our SBS and BSG segment, was $84.8 million and $449.2 million, respectively, as of June 30, 2024.

Additionally, the changes to other intangibles included effects of foreign currency exchange rates of $0.6 million.
