Security-based swap execution facility
Security-based swap execution facility has the same meaning as in section 3(a)(77) of the Act (15 U.S.C. 78c(a)(77)) but does not include an entity that is registered with the Commission as a clearing agency pursuant to section 17A of the Act (15 U.S.C. 78q-1) and limits its security-based swap execution facility functions to operation of a trading session that is designed to further the accuracy of end-of-day valuations.
