The Company reviews goodwill at least annually for potential impairment, as of October 1, and more frequently, if events or changes in circumstances suggest that impairment may exist. See Note 2, "Summary of Significant Accounting Policies" for additional information on the Company's policy for assessing goodwill for impairment.

The Company performed its annual goodwill impairment testing as of October 1, 2024, 2023 and 2022, and determined that no adjustments to the carrying value of goodwill were necessary as it was more likely than not that the fair values of our reporting units are above their carrying values and that no impairment exists. No goodwill impairments were incurred for the years ended December 31, 2024, 2023, and 2022.
