Are you sure that it was Philip Morris that had the interest, rather than its former subsidiary Miller Brewing. I point this out because PM sold Miller to South African Breweries. One might presume that Miller's interest in Presidente went with it, though I'm not sure. Beer and tobacco may not have been treated the same way. The exact details of this relationship have always been complicated and somewhat hidden.
In any case, is there really reason to believe that Altria Group is involved in Banco Leon at all?
Finally, the way Hippo is governing, any bank could lose a ton of money. At some point, even the Leons would have to cut and run. The Grullons too, except where would they run to?
