FWIW
I read in an old Sports Illustrated article that his actual out of pocket equity investment in the original transaction was $170k for a little over half interest. Presumably the balance was financed. In addition, because he died this year, any tax liability associated with his death has been eliminated. The IRR on the deal is thru the roof. That's why the limited partners have always been relatively quiet and you never hear about them. While they have cringed over the years over all the bombast, they knew they were making a ton of money.
If you go to SI Vault you can read the old articles on the man. While not always pleasant to work for, his philanthropy (mostly anonymous) was significant as was his work ethic. A very interesting man who accomplished a lot in his life.
