By reputation, so perhaps I'm off. But I doubt it. Put yourself in his place. He's worth a billion. He's got tens of millions in liquid assets. He does not live an overly extravagant lifestyle. He founded the company and built it from nothing to a multi-billion dollar concern. He's still working every day even though he's in his mid-80's. Doesn't sound like he's either needing to sell or wanting to stop working on the company.
