*At the end of 2004, ACSI adopted the North American Industry Classification System (NAICS) to replace the Standard Industrial Classification (SIC) for the organization of ACSI measured sectors and industries. The NAICS classification moves the limited-service restaurant industry from the Retail sector, measured in fourth quarter, to the Accommodation & Food Services sector, measured in first quarter. Therefore, the Q4 2004 measurement of the limited-service restaurant industry was delayed until Q1 2005 and the industry will continue to be measured in the first quarter thereafter.
