Unallocated expense includes corporate costs not allocated
to the operating segments, including, for the period ended
December 31, 2001, goodwill amortization resulting from acquisitions
prior to 1998. For the period ended December 31, 2002, unallocated
expense does not include goodwill amortization as result of
the Company adopting SFAS No. 142, as described in Note 5.
Unallocated expense also includes the recognition of an expense
or a reduction to expense for deferred stock compensation plans
resulting from stock price changes as described in Note 17.
The cost attributable to share-based plans expense is not allocated
to other business segments except for the portion related to
BCC. Depreciation and amortization relate primarily to shared
services assets.
