Goodwill and Intangible Assets Disclosure [Abstract]

6. Goodwill and Intangible Assets

During the third quarter of 2025, we completed our annual impairment test of goodwill, which was based on a qualitative assessment, and concluded that there was no impairment. A qualitative assessment is designed to determine whether we believe it is more likely than not that the fair values of our reporting units exceed their carrying values. A qualitative assessment includes a review of qualitative factors, including company-specific (financial performance and long-range plans), industry, and macroeconomic factors, and a consideration of the fair value of each reporting unit at the last valuation date.

Goodwill and acquired intangible assets consisted of the following:
