The Forbes 500 was an annual listing of the top 500 American companies prouced by Forbes Magazine. The list was calculated by combining five factors: sales, profits, assets, market value, and employees. The list was last issued in March 2003 (based on 2002 data for the companies); it is no longer calculated each year and has been replaced by the Forbes Global 2000, which includes non-U.S. companies but is calculated on a similar basis as the old Forbes 500 (although it does not include employees).
