Tip: When an OTCBB company fails to file its reports on time, the FINRA will add a fifth letter "E" to its four-letter stock symbol. The company then has 30 days to file with the SEC or 60 days to file with its banking or insurance regulator. If it's still delinquent after the grace period, the company will be removed from the OTCBB.

Which Companies Don't Have to File Reports With the SEC?
Smaller companies — those with less than $10 million in assets — generally do not have to file reports with the SEC. But some smaller companies, including microcap companies, may choose voluntarily to register their securities with the SEC. As described above, companies that register with the SEC must also file quarterly, annual, and other reports.
