—————————— (1)See Note 3. “Business Acquisitions” to our consolidated financial statements for discussion of our business acquisitions. We performed our annual impairment analysis in the fourth quarters of 2024 and 2023. ASC 350-20 allows companies to perform a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying value to determine whether it is necessary to perform a quantitative goodwill impairment test. Such qualitative assessment considers various factors, including macroeconomic conditions, industry and market considerations, cost factors, the overall financial performance of a reporting unit, and any other relevant events affecting our company or a reporting unit. We performed a qualitative assessment for our modules business in each respective period and concluded that it was not more likely than not that the fair value of the modules business was less than its carrying amount. Accordingly, a quantitative goodwill impairment test for the modules business was not required in any period presented.
