Redeemable Noncontrolling Interest [Table Text Block] | Redeemable Non-controlling Interests Many of our acquisitions include provisions under which the non-controlling equity owners may require us to purchase additional interests in a subsidiary at their discretion. Redeemable non-controlling interests are adjusted quarterly, if necessary, to their estimated redemption value, but not less than their initial fair value. Any adjustments to the redemption value impact retained earnings or additional paid in capital, except for foreign currency translation adjustments. The following table presents changes in our redeemable non-controlling interests.

Goodwill Disclosure | Goodwill is the excess purchase price remaining from an acquisition after an allocation of purchase price has been made to identifiable assets acquired and liabilities assumed based on estimated fair values. The Company transferred certain agencies between operating segments as of January 1, 2024 which resulted in certain changes to our reporting units and reportable segments. We have allocated goodwill to our reporting units using a relative fair value approach. In addition, we completed an assessment of any potential goodwill impairment for all impacted reporting units immediately prior and subsequent to the reallocation and determined that no impairment existed. The following table sets forth details of changes in goodwill by reportable segment of the Company:
