The Participants requested an exemption from the SEC from certain provisions of the CAT NMS Plan so that social security numbers/taxpayer identification numbers for natural persons would not be reported to the CAT. If the exemption is granted, the Plan Processor will generate a unique CAT Customer ID (“CCID”) using a strategy developed in collaboration with Industry Members. The CCID strategy uses a two-phase transformation that avoids the receipt or retention of social security numbers or individual taxpayer identification numbers in the CAT. Industry Members will not receive the generated CCID. The resultant CCID and an associated Firm Designated ID (“FDID”) will be stored by the Plan Processor for further processing. As noted above, the Participants requested an exemption from the SEC from certain provisions of the CAT NMS Plan so that the dates of birth and account numbers of individual customers would not be reported to the CAT Central Repository. Instead of reporting dates of birth and account numbers for individuals, Industry Members would report to the CAT years of birth and FDIDs for accounts for individuals.
