This Top 100 Businesses and Economic Outlook special report is a collaboration of The Inquirer, The Philadelphia Daily News and Philly.com.

How it was reported: Stock performance, market capitalization and other share-related data were collected from Bloomberg News, which compiles information from company reports, stock exchange data and Securities and Exchange Commission documents.

Data for the largest employers were provided by the employers, with the exceptions of Sears and Bank of America, for whom it was necessary to calculate estimates because they refused to provide information. Partial data and a list of companies considered for inclusion in the list were obtained from Pennsylvania Labor Department data, from county and municipal bond documents, from lists published by the Greater Philadelphia Chamber of Commerce and from publicly available lists.

We'd like your feedback: Do you have updated information on a regional company? Did we miss any major companies? Please contact Inquirer reporter Joseph N. DiStefano or editor Thomas Ginsberg - click on names to send e-mail. (Please continue to send routine press releases to Inquirer Business News.)
