Therefore, the ECB and its predecessor, the European Monetary Institute, have done so themselves in their so-called Convergence Reports. These Reports assess whether a Member State qualifies for the introduction of the euro and they also contain a chapter on legal convergence. They develop features of institutional, personal and financial independence.
In addition, they identify areas in which statutes of NCBs are likely to require adaptation in view of the integration of NCBs in the Eurosystem. These Reports thus gave guidance to national legislators in the process of adapting such statutes. As a result, new statutes of NCBs have come into existence, which, as far as Eurosystem-related tasks are concerned, often contain very similar provisions.
