A 1991 estimate by Gak Nederland, for instance, put the level of white fraud in that year at around 21 million guilders. The findings of a survey by the GUO likewise point to limited savings. The Netherlands Court of Audit therefore believes that action by the Minister of Social Affairs and Employment is called for. The Netherlands Court of Audit is of the opinion that the LISV should draw up further rules for the implementing bodies regarding contractual relationships and the control exercised by the implementing bodies and operating companies in the private leg of holding companies. In the opinion of the Netherlands Court of Audit, the situation regarding the SFB group gives grounds for further reflection on how this data may be used by holding companies.
Standardisation is essential for the efficient and reliable exchange of information.
Although the process of standardisation has already been initiated by the implementing bodies, the Netherlands Court of Audit doubts whether the process will be completed by 2001 if it continues at its present pace. This is an important consideration, given that new implementing bodies will be able to enter the market from that year on. The shortcomings shown by the implementing bodies are all the more serious when seen in the light of the proposed extension of the electronic exchange of data to the municipal social services and manpower services. The implementing bodies' own data administration must be in order, i.e. the data must be reliable and supplied in a standardised form, before data can be exchanged with other sectors. Other sectors may, moreover, be able to learn from the experiences and shortcomings of the implementing bodies.
