CGR will trade on the otcbb until they discontinue required reporting to the SEC. At that point, they will trade on the pink sheets in the U.S. The problem will be the lack of transparency, but frankly the savings in expensive listing and regulatory costs will very likely be worth the move. They will have the option of listing on the OTCQX if they want to maintain a cheap, verified form of disclosure.
