(9)In order to be covered by the definition of money market instruments in Directive 85/611/EEC, a financial instrument should fulfil certain criteria, notably it must normally be dealt in on the money market, it must be liquid and it must have a value which can be accurately determined at any time. It is necessary to ensure a uniform application of those criteria taking into account certain market practices. It is also necessary to clarify that the criteria have to be understood in coherence with other principles of Directive 85/611/EEC. The definition of money market instruments should extend to financial instruments which are not admitted to or dealt in on a regulated market and for which Directive 85/611/EEC sets out criteria in addition to the general criteria for money market instruments. It was therefore equally necessary to clarify those criteria in the light of investor protection requirements and taking into account principles of the Directive such as portfolio liquidity, as resulting from Article 37 thereof.
