Paychex Named One of ''World's Most Ethical Companies'' by Ethisphere Magazine

ROCHESTER, N.Y.--(BUSINESS WIRE)--

Paychex, Inc. has been named one of the "World's Most Ethical Companies" by Ethisphere Magazine, a national publication for corporate executives that examines the correlation between ethics and profit. The companies selected for this prestigious honor were recognized for strong leadership in ethics and compliance, the advancement of social and ethical issues, and positive community engagement.

"Since Paychex was founded in 1971, the employees of our company have shown their strong commitment to the highest professional and ethical standards. That tradition has allowed our business and reputation to thrive," said Jonathan J. Judge, Paychex president and CEO. "From our board of directors, to our management team, to our employees, Paychex is a company that prides itself on doing what's right. This recognition of our dedication to ethical leadership is a tremendous honor."

The editors of the magazine chose fewer than 100 companies from several thousand organizations, representing 30 industries that they analyzed over a six-month period. The process included reviewing companies' codes of ethics, litigation and regulatory infraction histories; evaluating investment in innovation and sustainable business practices; looking at companies' activities to improve corporate citizenship; studying nominations from senior executives, industry peers, suppliers and customers; and working with consumer action groups for feedback and rating.

"This was a rigorous process that identified a select group of companies that were unequalled in their industries for their commitment to ethical leadership and corporate social responsibility. These organizations go beyond making statements about doing business ethically; they translate those words into action," said Alex Brigham, executive editor of Ethisphere Magazine.

Ethisphere editors also declared that Paychex is "Ethics Inside Certified," an additional designation for companies that can provide affirmative anecdotal and real evidence about adequate internal efforts to promote ethical behavior by employees. This is done through discussions between company executives and magazine editors and experts.

Ethisphere Magazine has a circulation of 65,000 global board members, CEOs, general counsel, chief ethics and compliance officers, and institutional investors. It offers insight on gaining market share and creating sustainable competitive advantage through ethical business practices and corporate citizenship.
