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 IndustryWeek 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 2014 is weighted at 30% and 2013 contributes 20%.
