However you can google foreign exchanges and look at their marketing practices. They are very agressive in looking for companies to list-that's no secret! But then look at their conditions,requirements,history of firms recently listing,etc. and try to find a pink sheet company that took the step with a PPS not much over a penny and with A/S of 5 bil!
