[ by Howard Haykin ] NYSE and NYSE MKT DMMs (Designated Market Makers) were provided with guidance from NYSE-Regulation on NYSE Rule 103B, VI(A), starting with NYSE Rule 103B, VI(A)(5), which provides that rights traded on the Exchange are not subject to the security allocation provisions specified in the rule and are assigned, when issued, to a DMM unit by the Exchange. Given the short-term nature of rights, the Exchange will generally assign rights to the DMM unit that has been allocated the underlying security unless the issuer requests a specific DMM unit in writing.  The Exchange will notify the DMM in the underlying security if the issuer has made such a request.
