Fincen form 105?

[santosg]

How on earth could anyone justify 1.4 or 1.6 billion usd after spending a year in Dubai and then returning home to the u.s. and declaring such amount? The oil business? How could such amount ever be justified using fincen form 105? Could such amount be feasibly justified under any circumstances? What could justify this much money after spending a year in dubai and returned home and wanted to declare it all? Conglomerate investor? Can any of you guys give me your opinion here? Thank you.
