I will answer the first part of the question and Mr. Moffet will answer the second part.
As far as a comparative analysis is concerned, every time we propose creating measures, be they with regard to environmental intervention or regulations, it doesn't matter, we must systematically conduct a comparative analysis to see what other countries are doing. This is done automatically in the course of our work. So it's something we are very familiar with.
We deal with issues on a case-by-case basis to find out what was done by which country, whether it's a country of the European community or any other country, and we then explain why we adopted a certain position with regard to the method in question.
I will let Mr. Moffet respond to your question on the REACH model.
