Effective February 5, 2004, Productivity and Cost measures for the manufacturing sector
are now reported using the 2002 North American Industry Classification System (NAICS).
Because of the reclassification, these measures are not directly comparable with
manufacturing measures published on or before Dec. 3, 2003.
