Confidence rating:

The majority of Koch's fortune is derived from the proceeds of the sale of his stake in Koch Industries to his brothers, David and Charles, for $435 million in 1983. The value of his investments has been adjusted for taxes and market performance.

Koch owns 80 percent of Oxbow Group, a group of more than two dozen companies. It includes Oxbow Carbon & Minerals, the world's largest producer of calcined coke. Oxbow Group has annual sales of more than $3.7 billion and more than $1.7 billion in assets, according to the group's LinkedIn page.

Oxbow Group's valuation is based on the average of enterprise value-to-Ebitda multiples of four publicly traded peer companies: Glencore, Mitsui, Bunge and Mitsubishi. The Ebitda figure used in the analysis was calculated by applying a 6 percent margin, based on advice from Andrew Cosgrove, a Bloomberg Intelligence analyst.

The billionaire's real estate in Colorado and Florida is valued on 2018 assessor valuations and a house in Massachusetts is valued on a New York Times report of its purchase price.

Brad Goldstein, a spokesman for Koch at Oxbow, declined to comment on Koch's net worth.

Biography

Birthdate: 5/3/1940
Family: Married, 6 children
Education: Culver Military Academy, Massachusetts Institute of Technology, Massachusetts Institute of Technology, Massachusetts Institute of Technology

Bill Koch was born in Wichita, Kansas, in 1940. His father, Fred Koch, co-founded an engineering company in 1925 that specialized in oil refining and oil-related processes. His older brother Charles took over the company on their father's death in 1967, rechristening it Koch Industries. Bill joined Koch Industries in 1970, and received a doctorate degree in chemical engineering from MIT the following year.

A fraternal feud erupted in 1980, when Bill and his older brother Frederick tried to unseat Charles as CEO in a failed boardroom coup. The duo agreed to sell their shares back to the company for $1.1 billion in 1983, of which $435 million went to Bill. They sued two years later claiming they were underpaid. A 15-year legal battle ensued that was ultimately decided in favor of Charles and David, Bill's twin brother, in 2000.

After selling his stake in Koch Industries, Bill started Oxbow in 1983, in Dover, Massachusetts. Over the next three decades, he developed the company into a mining and commodities marketing firm. Other accomplishments include winning the Americas Cup, the world's oldest sailing race, in 1992, and building a Wild West town in Colorado's Rocky Mountains. He's also a collector of maritime and Western memorabilia.

Koch lives in Palm Beach, Florida, with his wife, Bridget. The couple have six children from different marriages.
