The following table provides approximately the past year's PPI data, with
the left-hand column breaking out the numbers incorporating the Labor
Department's new seasonal-adjustment factors. The January 2004 result also
incorporates the change to the use of the 2002 North American Industry Classification
System (NAICS).
The text after the table are explanations released earlier today by the
Labor Department.

NOTE: Data are seasonally adjusted. *Data for
1/2004 and forward incorporate the use of the
2002 North American Industry Classification
System. "New Seasonals" column above incorpo-
rates revised seasonal-adjustment factors.
NAICS Conversion
The net output price indexes have been converted from the 1987 Standard
Industrial Classification (SIC) basis to the 2002 North American Industry
Classification System (NAICS) basis with the release of January 2004 indexes. The
NAICS conversion involves major definitional changes to many of the currently
published SIC-based indexes. SIC-based indexes are no longer produced or
published.
Recalculation of Seasonal Adjustment Factors
Effective with this release, seasonal adjustment factors have been
recalculated to reflect price-movement patterns during 2003 for stage-of-processing
(SOP) and commodity-grouping indexes. This routine annual recalculation may
affect previously published seasonally adjusted indexes and percent changes for
January 1999 through December 2003.
