(46)The criteria that financial instruments should meet to be considered eligible investments for the CCP, should take into account Principle 16 of the CPSS-IOSCO Principles — in order to ensure international consistency. In particular, a CCP should be required to apply restrictive standards concerning the issuer of the financial instrument, the transferability of the financial instrument and the credit, market, volatility and foreign exchange risk of the financial instrument. A CCP should ensure that it does not undermine measures taken to limit the risk exposure of its investments by having excessive exposures to any individual financial instrument, type of financial instrument, individual issuer, type of issuer or individual custodian.
