Rausing, 91, and his wife Marit sold their 50% stake in the Tetra Pak carton operation for £4.4bn to his late brother Gad, whose children Kristen and Jorn (qv) now control the business. The East Sussex-based couple are more preoccupied with spending their wealth on good causes.
The main family charitable vehicles are the Sigrid Rausing Trust, run by their daughter Sigrid, which has donated more than £275m in the past two decades – including £27.5m last year – and the Arcadia Fund, run by another daughter, Lisbet. All investment profits from the family's Alta Advisers vehicle go to charity, though in 2015-16 these dipped to £435,000 on £42m turnover.
More recently Rausing has invested in products such as Ecolean, an environmentally friendly packaging material made from chalk, and took control of its Swedish manufacturer in 2000. His stake there is worth nearly £230m and his US shares will have benefited from surging Wall Street values.
