Bloomberg: When Ikea’s Ingvar Kamprad died Saturday at age 91, he was ranked No. 8 on the Bloomberg Billionaires Index thanks to his control of a global retail fortune valued at $58.7 billion. His wealth will now be dissipated because of a unique structure put in place by Kamprad to secure the long-term independence and survival of the Ikea concept. Kamprad disputed his status as one of the richest men on the planet, having decades earlier placed control of the world’s largest furniture seller into a network of foundations and holding companies.”
