"Aon is committed to providing a diverse and productive work environment, and we are honored to achieve this recognition from the Human Rights Campaign Foundation for the second year in a row," said Greg Case, chief executive officer of Aon. "This award is indicative of our position as the destination of choice for the best talent, not only in the insurance and human consulting industries, but within the global business community."

The Corporate Equality Index rated 583 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.

Aon's goal for its global diversity initiative is to create a world-class magnet for talent that nurtures the unique background, skills and creativity of the firm's 36,000 global colleagues. Since 2006 Aon has launched two global metrics for measuring success on its diversity objectives -- more women in senior management positions within the company, and four regionalized diversity strategies -- with the objective of embracing the client needs and talent imperatives of each community served by Aon, and to cascade those strategies from the executive level all the way down to the newest employee. Aon's diversity and inclusion goals focus on continuous improvement by hiring the best, building the best and being the best.
