Olympus hid $1.7B in losses for 20 years — then the CEO who exposed it was fired

Olympus Corporation was a Japanese optical and medical equipment giant, holding 70% of the global endoscope market. Beginning in the 1990s, the company hid investment losses through a tobashi scheme — moving losses off the balance sheet through a web of shell companies in the Cayman Islands. The concealment ran for over 20 years.

The fraud worked through inflated acquisition payments. In 2008, Olympus paid ¥73.5 billion ($965 million) for three tiny companies (Altis, Humalabo, NewsChef) worth a fraction of that price. On the $2.2 billion acquisition of Gyrus Group, a $687 million advisory fee was paid to shell firms — 31% of the deal, compared to the typical 1–2% for M&A advisory.

British CEO Michael Woodford was appointed in October 2011 and uncovered the fraud within weeks. He confronted the board, was fired after just 14 days, and went public. The scandal wiped out 80% of Olympus's market value. Woodford later won a £10 million settlement. Three former executives received suspended sentences in 2013. The company remained listed but its reputation as a trusted Japanese corporate giant was permanently damaged.
