(1) In addition to goodwill from acquisitions completed within the period, in accordance with the accounting for business combinations, we recorded adjustments to goodwill for the effect of changes in the provisional fair values of the assets acquired and liabilities assumed during the measurement period (up to one year from the acquisition date) as we obtained new information about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. Such adjustments are not material to our consolidated financial statements.
During the first quarter of 2024, we completed the annual impairment test for goodwill and the indefinite-lived intangible asset and determined that these assets had not been impaired as of the test date, January 1, 2024. No other events or circumstances changed during the year ended December 31, 2024 that would indicate that the fair values of our reporting unit and indefinite-lived intangible asset are below their carrying amounts.
