Essentially, we would be paid the market price. By that I mean.... All countries have contributed a certain amount of capital to the bank. The bank will invest that in loans and other projects that will have a return. Most of that return will go back into the bank's retained earnings. Our share of those retained earnings would be reflected in the sale price back to us, or any members who chose to sell back their shares.
