If GSRE would become fully reporting they would leave the "Pink Sheets" tier of the OTC exchange and be UPLISTED to a higher exchange most likely the OTCQB.
This is a big deal in the eyes of investors due to the fact that the company must file audited financials reports to the SEC Edgar database and are legally responsible for the contents of these filings.
OTCQB is the middle tier of the OTC market. OTCQB companies report to the SEC or a U.S. banking regulator, making it easy for investors to identify companies that are current in their reporting obligations. There are no financial or qualitative standards to be in this tier. OTCQB securities may also be quoted on the FINRA BB. The OTCQB allows investors to easily identify reporting companies traded in the OTC market regardless of where they are quoted.
