Looks to me they are required to report to maintain the pink status.
Transparent Tier Lower than the Trusted tier, this one is made up of the following:
Pink Quote OTCBB. These companies are listed in both the pink sheets system and the OTCBB. The bulk of all OTC stocks will be dually-listed. The OTCBB requires these companies to report to the SEC frequently. OTCBB Only. This is obvious, as these are companies only listed on the OTCBB market. Current Information. These are companies that are providing information with either the SEC or the OTC Disclosure and News Service. This information is no more than six months old. In order for companies to stay at this tier and not be moved down, they need to have filed a quarterly or annual report within 75 days after the last quarter has ended. The pink sheet OTC market will verify that the information has been posted.
