In setting the definition under this subparagraph, the Commission shall consider the person’s relative position in uncleared as opposed to cleared security-based swaps and may take into consideration the value and quality of collateral held against counterparty exposures. (C) Scope of designation .— For purposes of subparagraph (A), a person may be designated as a major security-based swap participant for 1 or more categories of security-based swaps without being classified as a major security-based swap participant for all classes of security-based swaps.
