Olav Thon, Norway's richest man.

Norway's richest man has handed a chunk of his personal wealth, including his listed real estate holding company, to a charitable foundation, marking his exit from a self-built business empire.

Olav Thon, whose wealth is estimated at 27 billion crowns ($4.39 billion) by Kapital magazine, handed his 71.9 percent stake in Olav Thon Eiendomsselskap ASA to his newly created foundation, starting off the new entity with about $1.3 billion, based on the firm's market capitalization.
