The Star Tribune 100 is a ranking of the largest Minnesota-based publicly traded companies, measured by revenue from continuing operations. Revenue for bank holding companies is total interest income plus total noninterest income.

We have included companies such as Medtronic, Pentair and Stratasys that, while officially domiciled in foreign countries, have management headquarters in Minnesota. We have excluded companies that do not trade on major stock exchanges.

The Star Tribune contacted companies by mail, e-mail or telephone. Financial information also was obtained from company news releases, Securities and Exchange Commission filings and Thomson Reuters.

Profits are defined as net income before being adjusted for extraordinary items. Market capitalization is as of April 29. Financial information gathered was for the 12-month period ending in November, December or January. In the case of companies that do not report on a calendar year, data from the trailing four quarters that ended closest to Dec. 31 were used.
