Financial Advisor:  “Paul Allen’s family office will live long and prosper. The billionaire’s vast holdings at Vulcan Inc. — with real estate, art, sports teams and venture capital stakes — would take years to unravel, if that’s even what he wanted. Allen, who died Monday, had no spouse or children to divide his empire. But there are many others with interests at stake, including family, staff and charities, as well as potential investors eager to snap up pieces.”
