Corporate Equality Index 
In 2006, Perot Systems was one of three companies, of 1,520 surveyed, to receive the lowest possible rating on the Corporate Equality Index survey conducted by the Human Rights Campaign. In 2009, the company was one of only two to receive a zero ranking in the survey, which evaluates "employers and their policies and practices pertinent to lesbian, gay, bisexual, and transgender employees". The company previously offered domestic partner benefits to its employees, under a policy which was canceled in 1998. In the 2006 ranking, Perot was cited for "[engaging] in action that would undermine the goal of [...] equality". Dell, on the other hand, has been ranked with a perfect score on the Corporate Equality Index for 2010.
