(13)Pursuant to Directive 85/611/EEC, techniques and instruments relating to transferable securities or money market instruments for the purpose of efficient portfolio management do not fall under the definitions of transferable securities and money market instruments. To clarify the boundaries of those definitions it is necessary to set out criteria to identify the transactions which would fall under those techniques and instruments. It is also necessary to recall that those techniques and instruments have to be understood in coherence with the other obligations of a UCITS, particularly as regards its risk profile. That is to say, they must be consistent with the rules laid down by Directive 85/611/EEC on risk management and on risk diversification, as well as with its restrictions on short sales and borrowing.
