Issuers with stock trading on the OTC Bulletin Board (OTCBB) need to be aware that a corporate transaction, which results in the issuance of a new cusip number, triggers an automatic change in the ticker symbol. According to the folks at the OTCBB, the issuer is “not allowed” to reserve or request a specific ticker symbol. No ifs, ands or buts about it. While no one I spoke with at the OTCBB could tell me why requests and/or reservations are not allowed, the only possible conclusion is that allowing reservations on the OTCBB would reduce the pool of ticker symbols available to Nasdaq traded issuers.
