The Place of the Relevant Intermediary Approach (PRIMA) is a conflict of laws rule applied to the proprietary aspects of security transactions, especially collateral transactions. It is an alternative approach to the historically important look-through approach, and was in its earliest form the basis for the initial draft of the Hague Securities Convention. Unlike the look-through approach, PRIMA does not look through the various tiers of intermediaries to the underlying securities. Rather, it stops at the level of the intermediary immediately above the parties to the pledge or transfer. Its important advantage is that it subjects an investor's interest in securities to the law of a single jurisdiction, even where evidence of underlying securities is situated in many different countries, or where various issuers in a single portfolio is involved. This provides certainty and clarity for all parties involved. It is a matter of debate whether PRIMA constitutes a development of the traditional lex rei sitae principle or should be regarded as a new concept. PRIMA was adopted in a number of jurisdictions as the conflict of laws rule to be applied to the proprietary aspects of collateral transactions. It has given way, with the Hague Securities Convention, to the approach described below. Type I PRIMA The so-called Type I PRIMA dates back to the late 1960s, in Belgium. Under Belgian law, the interest in respect of the underlying securities held by an investor and recorded on the books of its intermediary is treated as a different asset from the underlying securities. Thus the Belgian approach is an application of PRIMA, as well as being linked to the lex rei sitae tradition. Such an approach causes problems in some legal systems, notable of which are those of Japan and Germany. Under both their systems, an investor would be treated as the direct owner of the underlying securities even though the security is held through tiers of intermediaries. The direct ownership in the underlying securities makes it difficult to argue that the location of the asset is at the level of an intermediary. Adoption in Europe; and anticipated changes Article 9(2) of the European Union's Settlement Finality Directive of 1998 introduced PRIMA in all European Union member states. In Germany, where investors have direct ownership rights in underlying securities, implementing Art 9(2) into domestic law has severed the connection with the traditional lex rei sitae approach.
