Building an ethical corporate culture can be daunting under even the best of circumstances. Add to the mix a workforce located in multiple countries, each with its own culture, language, and legal system, and the challenges are magnified.

Yet, companies can’t ignore these obstacles, given the increasingly global economy. In 2011, nearly half (46 percent) of revenue of the S&P 500 companies that provide information on global sales came from outside the United States. New anti-corruption laws around the globe and stricter enforcement of existing laws provide another strong incentive for companies to make it a priority to foster an ethical culture.
