Rio, Loch was delisted from the OTCBB about 3 years ago, and started trading on the Pink Sheet. Pink Sheet and OTCBB are not the same:
"The OTCBB is distinct from the Pink Sheets. The Pink Sheets are not owned or operated by The Nasdaq Stock Market, Inc. or the NASD. The Pink Sheets LLC is a privately owned company whose Electronic Quotation Service provides an Internet-based, real-time quotation service for OTC equities and bonds."
