Business Integrity-Code of Conduct

Corruption has probably been around as long as power has existed. That doesn’t make it acceptable; nor is it a waste of time to try to do something about it. Because corruption does enormous damage. It costs the world’s poor billions of US dollars a year, in money siphoned off by local elites. It increases inequality and unfairness, hampers economic development and drives up prices for products and services.

And while a refusal to bribe will sometimes lead to a loss of business, we have learned from experience that there are many people who prefer to deal with a company with a strong no-bribery policy.
