That's like saying that people who, as students, save money in a "closed" account is not worth anything (we have some saving accounts with tax benefits where you can't withdraw that money unless you spend it on a house).
You have a point in that you can't expect to sell those shares (at least not for a decent price), but if you have faith in TRW and their ability to list on HKSE (or similar) in 2-3 years, then I have to strongly disagree; we're talking about a 3-bagger in 2-3 years (if the $3.4 value is correct). That would be mind-blowing results for pretty much every retail investor...
Traderfan I think it is nonsense to think that shares that are not traded on a stock exchange have no value. My guess is that fewer than one percent of this kind of companies in my country are listed on a stock exchange. I have read that some think it is fair with a 50% discount for companies that are not traded on a stock exchange. At this stage nobody knows how difficult it will be to sell or buy shares in TRW. I think the real value of these shares will partly depend on how difficult it will be to buy and sell them.
