Chicago, September 14  - Aon Corporation, the leading global provider of risk management and human capital consulting, today announced that for the third straight year it has received a perfect 100 percent rating in the Human Rights Campaign Foundation’s Corporate Equality Index. Aon was one of 350 major U.S. businesses to receive a 100 percent rating.

The Corporate Equality Index (www.hrc.org/cei) rated 590 businesses this year on the extent to which they protected their gay, lesbian, bisexual and transgender employees, consumers and investors. Ratings are based on such factors as nondiscrimination policies, diversity training and benefits for domestic partners and transgender employees.

“This award is a tremendous tribute to our 37,000 global Aon colleagues who work hard every day to provide a diverse and productive work environment, said Greg Case, president and chief executive officer of Aon. “Winning this recognition for the third year in a row clearly demonstrates to the marketplace that Aon is the destination of choice for the best talent, not only in the insurance and human capital consulting industries, but within the global business community. We are very honored to receive this acknowledgement, and we will continue to focus our efforts on hiring the best, building the best, and being the best.”

Aon’s goal for its global diversity initiative is to create a working environment that becomes a world-class magnet for talent and which nurtures the unique background, skills and creativity of the firm’s workforce. Aon continues to focus on two global diversity initiatives - - more women in senior management positions within the firm, and four regionalized diversity strategies - - with the objective of embracing the needs of clients and the talent imperatives of each community served by Aon, and to cascade those strategies from the executive level all the way down to the newest Aon colleague.
