Basis of Presentation:

     The Corporation operates in three reportable business segments: Power Tools
and  Accessories,  Hardware and Home  Improvement,  and  Fastening  and Assembly
Systems.  The Power Tools and Accessories  segment has worldwide  responsibility
for the  manufacture  and sale of  consumer  and  professional  power  tools and
accessories,  electric  cleaning and lighting  products,  and electric  lawn and
garden tools, as well as for product service.  In addition,  the Power Tools and
Accessories  segment has  responsibility  for the sale of  security  hardware to
customers in Mexico, Central America, the Caribbean,  and South America; for the
sale of plumbing products to customers outside the United States and Canada; and
for sales of household  products.  The Hardware and Home Improvement segment has
worldwide  responsibility  for the  manufacture  and sale of  security  hardware
(except  for the sale of  security  hardware  in Mexico,  Central  America,  the
Caribbean,  and South America).  On September 30, 2003, the Corporation acquired
Baldwin  Hardware  Corporation  and  Weiser  Lock  Corporation.  These  acquired
businesses  are  included in the  Hardware  and Home  Improvement  segment.  The
Hardware  and  Home  Improvement   segment  also  has   responsibility  for  the
manufacture  of  plumbing  products  and for the sale of  plumbing  products  to
customers in the United States and Canada.  The  Fastening and Assembly  Systems
segment has worldwide  responsibility  for the manufacture and sale of fastening
and assembly systems.

     In January  2004,  the  Corporation  sold two  components  of its  European
security hardware  business.  The divested  businesses and the remaining portion
that is expected to be sold in 2004 are treated as  discontinued  operations  in
the Corporation's  consolidated  financial  statements.  Sales,  segment profit,
depreciation  and  amortization,  and  capital  expenditures  set  forth  in the
preceding tables exclude the results of the discontinued operations.

     The  Corporation  assesses  the  performance  of  its  reportable  business
segments based upon a number of factors,  including  segment profit. In general,
segments  follow the same  accounting  policies as those  described in Note 1 of
Notes  to  Consolidated   Financial   Statements  included  in  Item  8  of  the
Corporation's  Annual Report on Form 10-K for the year ended  December 31, 2003,
except  with  respect  to  foreign  currency  translation  and except as further
indicated below. The financial statements of a segment's operating units located
outside  of  the  United  States,   except  those  units   operating  in  highly
inflationary  economies,  are generally measured using the local currency as the
functional  currency.  For these  units  located  outside of the United  States,
segment  assets and elements of segment  profit are  translated  using  budgeted
rates of exchange. Budgeted rates of exchange are established annually and, once
established,  all prior  period  segment data is restated to reflect the current
year's budgeted rates of exchange.  The amounts included in the preceding tables
under the captions "Reportable Business Segments" and "Corporate, Adjustments, &
Eliminations" are reflected at the Corporation's  budgeted rates of exchange for
2004. The amounts included in the preceding  tables under the caption  "Currency
Translation  Adjustments"  represent the difference between consolidated amounts
determined  using those  budgeted rates of exchange and those  determined  based
upon the rates of exchange  applicable  under  accounting  principles  generally
accepted in the United States.



     Segment profit excludes interest income and expense,  non-operating  income
and expense,  adjustments to eliminate intercompany profit in inventory,  income
tax expense,  and, for 2001, goodwill  amortization (except for the amortization
of goodwill  associated  with certain  acquisitions  made by the Power Tools and
Accessories and Fastening and Assembly Systems segments).  In addition,  segment
profit excludes  restructuring  and exit costs.  In determining  segment profit,
expenses relating to pension and other postretirement  benefits are based solely
upon estimated service costs.  Corporate expenses,  as well as certain centrally
managed expenses,  are allocated to each reportable  segment based upon budgeted
amounts.  While sales and transfers  between  segments are accounted for at cost
plus a reasonable  profit,  the effects of intersegment  sales are excluded from
the computation of segment profit.  Intercompany profit in inventory is excluded
from segment  assets and is  recognized  as a reduction of cost of goods sold by
the  selling  segment  when the  related  inventory  is sold to an  unaffiliated
customer.  Because the  Corporation  compensates  the  management of its various
businesses on, among other factors, segment profit, the Corporation may elect to
record  certain  segment-related  expense  items of an unusual or  non-recurring
nature in  consolidation  rather than reflect such items in segment  profit.  In
addition,  certain segment-related items of income or expense may be recorded in
consolidation  in one period and transferred to the various  segments in a later
period.
