7. Tyco International (2002)
Tyco International was a blue-chip Swiss security systems company, founded in 1960. The company’s former CEO Dennis Kozlowski and former CFO Mark Swartz were convicted of stealing $150 million and falsely inflating the company’s income by $500 million in 2002. Both of them were sentenced to 8-25 years in prison, and a class-action lawsuit forced Tyco to pay $2.92 billion to the affected investors.
