The Company's ICMS credits in Brazil are fully reserved. These credits do not expire. The Company is exploring other actions to utilize the credits. Charges and credits associated with normal ongoing activity are included in Cost of products sold in the Consolidated Statements of Income. Future material changes as a result of new legislation or a change in our operations will be reported separately.
Grantor trust assets consist primarily of cash surrender values in Company-owned life insurance policies held by a trust to be used for the eventual payment of employee deferred compensation. These assets are restricted from Company use until all obligations are satisfied.
