Thank you for sharing this link. Not sure what to think about it tho...
"In essence, Bain would value the special, riskier shares at pennies on the dollar. In one deal, employees invested about $23,000 in their IRAs. When the takeover target went public, those shares were worth about $14 million, and were worth about $23 million they finally sold the shares. That’s a 100,000% return."
Meaning, someone was risking their $23k in IRA. And looks like that investment opportunity was given to regular employees as well, meaning it wasn't a rigged up illegal trade based on some kind of insider information?
