Recital 27

The obligation to conclude transactions in derivatives pertaining to a class of derivatives that has been declared subject to the trading obligation on a regulated market, MTF, OTF or third country trading venue should not apply to the components of non-price forming post-trade risk reduction services which reduce non-market risks in derivatives portfolios including existing OTC derivatives portfolios in accordance with Regulation (EU) No 648/2012 without changing the market risk of the portfolios. In addition, while it is appropriate to make specific provision for portfolio compression, this Regulation is not intended to prevent the use of other post-trade risk reduction services.
