Okay, thanks for the info. I was asking more due to the general case; if a stock class has no voting rights and never will receive dividends, it is effectively worthless unless holders of other stock classes voluntarily give away their money (they won't).

I am a little puzzled at some of the latest innovations in the US stock markets. I can understand investing in a company that a small group of insiders will always have majority control in, as long as all owners are treated equally wrt. all forms of payouts. I really don't understand why the market would assign value to a stock class with no voting rights and no plausible scenario for returning capital to stockholders.
