What to do with stock that can't be sold on the market?
Suppose I own a number of shares of stock ABC, could be any number, say enough that I own 10% of the company. I fully understand that makes me 10% owner, entitled to 10% of the company in value, debt, assets, everything.
Now suppose that ABC sells to someone, or closes and sells their assets, or something such that it values $1 billion. So I'm entitled to $100 million.
My question: Where would I go to get my $100 million? Would I bring stock certificates somewhere? Is there an entity / clearinghouse that ensures my rights as a shareholder are upheld?
