The businesses sold and held for sale primarily represent unprofitable, non-strategic agencies which are expected to be sold within the next twelve months. Other - During the three months ended June 30, 2023, the amounts recognized were primarily related to pension and postretirement costs and a loss from the sale of an equity investment, partially offset by a gain on remeasurement of equity interests due to a change in ownership.

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.
