[6] The Foreign Corrupt Practices Act of 1977 generated new lines of business in auditing and compliance, so Kroll opened offices in Paris, Moscow, São Paulo, Tokyo, Singapore, and Manila.
Kroll forayed into banking and warehousing and built a reputation for pursuing financial crime across international borders by tracing and recovering assets.
Clients included law firms like Skadden, Arps and investment banks like Drexel Burnham Lambert (which hired Kroll in 1982 to perform due diligence on persons and companies that it was underwriting).
It was also hired to recover wealth that had been plundered by dictators, including the Philippines' Ferdinand Marcos and Haiti's Jean-Claude Duvalier.
In 1991 the government of Kuwait hired it to trace Saddam Hussein's corporate holdings around the world, including Hachette in France.
