What are the "listing" requirements for the OTCBB?

"Because the OTCBB is a quotation service for FINRA Market Makers and is, not an issuer listing service or securities market, there are no listing requirements that must be met by an OTCBB issuer. Accordingly, there are no financial requirements and there is no minimum bid price requirement . There are, however, eligibility requirements as well as other regulatory requirements relating to quotation activity and the display of quotations in OTCBB equity securities."
