Here is what I found: SEC Rule 15c2-11 was designed to allow non-reporting public company's securities to be quoted on NASDAQ's Over-the-Counter Bulletin Board ("OTCBB") by filing certain required disclosures through a FINRA member Market Maker. To be eligible for a quotation of its securities, the company's market maker must file a Form 211 with FINRA and the company must have sufficient free trading stock in its public float to satisfy Rule 15c2-11.
