METHODOLOGY

In order to determine America’s best companies to work for, 24/7 Wall St. independently reviewed employee ratings and testimonials on Glassdoor.com. Among the more than 400 companies reviewed, 24/7 Wall St. identified the 75 businesses that received the highest overall scores.

To be considered, a company had to have at least 300 reviews. Employers were also excluded if they were a government agency or bureau, a non-profit, or a subsidiary of a larger company. An exception was made for CareerBuilder, which is majority-owned by publishing and broadcast firm Gannett, since it is a joint venture between several companies.

Employee totals and revenue figures represent the most recent fiscal year data available. Sources include: company documents, Securities and Exchange Commission filings, S&P Capital IQ, and Forbes’ America’s Largest Private Companies 2013. For companies that do not provide data, Forbes estimates revenue.

In the case of S&P Capital IQ, employee totals are calculated as the equivalent of full-time employees, treating a part-time worker as “half” of a full-time employee. Employee counts for companies with franchises only count workers employed by the company.

Dollar conversions from S&P Capital IQ were used for companies that publish financial statements in currencies other than the U.S. dollar. In the case of companies where data is not from S&P Capital IQ, we converted revenue into dollars based on the effective exchange rate at the end of the company’s fiscal year.
