Redeemable Noncontrolling Interest [Table Text Block]

Redeemable Noncontrolling Interests

Many of our acquisitions include provisions under which the noncontrolling equity owners may require us to purchase additional interests in a subsidiary at their discretion. Redeemable noncontrolling 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 noncontrolling interests.
