National Quotation Bureau

The National Quotation Bureau is an American financial market founded in 1913 to collate and publish price information on bonds and stocks traded in the over-the-counter market. NQB was renamed Pink Sheets LLC in 2000, which in turn became Pink OTC in 2008. It is presently known as OTC Market Group, Inc. NQB was one of the prime originators of the ubiquitous “Pink Sheets", since it published stock information on pink paper and bond data on yellow sheets. Pink sheets refer to price quotes on over the counter shares, which are not listed and traded on traditional stock exchanges.
