That part is not written well (happens too much with SEC copy, especially when it comes from the "Investor Education" guys):
For stocks that trade in the OTC or the over-the-counter market, trading does not automatically resume when a suspension ends. (The OTC market includes the Bulletin Board and the Pink Sheets.) Before trading can resume for OTC stocks, SEC regulations require a broker-dealer to review information about a company before publishing a quote. If a broker-dealer does not have confidence that a company's financial statements are current and accurate, especially in light of the questions raised by the SEC, then a broker-dealer may not publish a quote for the company's stock.
That part in bold should read something like "does not automatically resume in the same venue . . ."
Because it does resume being *eligible* to trade--on the greys. That part *is* automatic. So the part about having a broker-dealer review info is poorly worded, too.
The "broker-dealer review" is the 15c2-11 process necessary to get off the greys.
