Creating the IW 50 Best US Manufacturers

The IndustryWeek 50 Best U.S. Manufacturers is IW's exclusive annual ranking of America's top-performing public manufacturers. IW compiles the list by ranking the IW U.S. 500 companies based on their financial performance in six key areas over a three-year period. This includes inventory turns, profit margin, asset turns, return on assets, return on equity, and revenue growth. The most recent year accounts for 50% of the calculation, while 2012 is weighted at 30% and 2011 contributes 20%.
