Confidence rating:

The majority of Liebherr's fortune is derived from her 50 percent stake in closely held Bulle, Switzerland-based Liebherr-International, a heavy machinery and construction conglomerate.

The business had revenue of 9 billion euros ($10 billion) and net income of 298 million euros in 2016, according to its annual report. It's valued using the average enterprise value-to-Ebitda, enterprise value-to-sales and price-to-earnings multiples of three publicly traded peers: Terex, Caterpillar and Hitachi.

The billionaire owns the company with her brother, Willi, and their respective children. The two siblings are credited with the fortune because of their operational and strategic roles at the company.

The value of her cash and other investable assets is based on an analysis of dividends, taxes and market performance.

Fiona Neuenfeldt, a spokeswoman for Liebherr-International, declined to comment on the net worth calculation.


Birthdate: 1949
Family: Married, 3 children

Isolde Liebherr was born in Kirchdorf an der Iller, Germany, in 1949, the year her father, Hans Liebherr, started a namesake construction-cranes maker. He moved the business from Germany to Switzerland in 1983 to avoid inheritance tax, and started Liebherr-International.

She started working in the family business in the mid-1970s, overseeing the real estate properties and hotel business. Her father died in 1993, when the closely held conglomerate had $2.5 billion in revenue, and had expanded to manufacturing heavy machinery for mining and aerospace operations as well as producing refrigerators. After her father's death, she took over Liebherr-International with her brother, Willi, having bought out their three other siblings.

Liebherr became the company's vice-chairman in 1999. She has three daughters and lives in Bulle.
