Some of the companies on this list were once among the most beloved, or at least most respected companies in America. How did the companies mentioned earn this dubious honor? The list was compiled based on scores in six areas. According to 24/7 Wall Street, those doing the rankings examined:

Employee opinions. Research firm Glassdoor.com helped out.

Shareholder return. The total return to stakeholders was compared to other companies in their broader market.

Consumer satisfaction. Research reports consulted ranged from JD Power to the University of Michigan American Customer Satisfaction Index.

Brand equity. Those who complied the report checked to see if the value of the brand had declined based on data from companies such as Corebrand, Interbrand, and BrandZ.

Media coverage. There was an analysis of media coverage conducted in-house by 24/7 Wall Street. Additionally the Flame Index (which analyses a cache of over 12K websites to determine the frequency of certain negative keywords) was consulted.
