Could this be the new rule that was put in late last year
Companies quoted on the OTC Markets are divided into four tiers, the OTCQX, the OTCQB, the OTC Pink and the Expert Market. Companies on the Expert Market provide the lowest level of disclosure in comparison to other OTC Market tiers. As a result, trading is limited to quotation on an unsolicited basis.
On October 15, OTC Markets reported that “2,247 former Pink No Information securities shifted to the Expert Market tier, where securities may only be quoted on an Unsolicited (customer order) basis. Quotes of securities in the Expert Market are “Unsolicited Only,” which means that trades of securities subject to unsolicited quotation in the Expert Market are only available to broker-dealers, institutions and other sophisticated investors, and not average investors.
Because of the restrictions imposed on securities quoted on the Expert Market, most investors will not be able to publicly sell their shares. Additionally, they will not have access to bid and ask prices or other information, including trading volume. As such, Expert Market shares are illiquid.
Companies moved to the Expert Market from another OTC Markets tier can apply to relist on the OTC Pink or other OTC Markets tier by becoming an SEC reporting company, submitting a new Form 211, and meeting OTC Markets requirements for the particular tier.
