Creating the IW U.S. 500
IndustryWeek partnered with Mergent Inc. to create the 2012 IW U.S. 500 ranking of the largest publicly held manufacturing companies with headquarters in the United States. Located in New York and Charlotte, N.C., Mergent has been collecting and delivering financial information for more than 100 years.
Led by Ricardo Angel, director of equity research, and Jeff Zazzaro, executive managing director, Mergent's global databases were used to identify all publicly held manufacturing firms meeting IW's selection criteria.
The actual revenue cutoff for inclusion on this year's IW U.S. 500 list was just over $1.1 billion. In addition to the team at Mergent, Erik Fine, a Charlotte-based information consultant, oversaw the data-collection effort.
The IW U.S. 500 includes:
• Manufacturing companies with a majority of their business in a manufacturing industry;
• Companies that generated less than 50% of revenues from manufacturing, but more revenue from manufacturing than the lowest-revenue-producing companies on this year's list;
• Oil and gas companies that derive at least 50% of their revenues from the refining of oil and gas products
• Companies that derive at least 50% of their revenues from manufacturing mined materials.
Mergent collected the financial data elements directly from reports distributed by the corporations. To more accurately reflect the companies' core businesses, only revenue numbers from continuing operations were used. The full IW 500 database is available at
www.industryweek.com/iw500-2012.
Where 2011 data is not available, 2010 data is provided. An "NA" appears where data was not available and an "N/M" shows in instances where data is not comparable (for instance, in profit growth where a company posted a loss in the previous year). For companies that have recently changed their fiscal-year end, the most recent 12-month figures have been used.
