Rule 17a-22

Supplemental Material of Registered Clearing Agencies

Within ten days after issuing, or making generally available, to its participants or to other entities with whom it has a significant relationship, such as pledgees, transfer agents, or self-regulatory organizations, any material (including, for example, manuals, notices, circulars, bulletins, lists, or periodicals), a registered clearing agency shall file three copies of such material with the Commission. A registered clearing agency for which the Commission is not the appropriate regulatory agency shall at the same time file one copy of such material with its appropriate regulatory agency.
