 And I'm going to present to you a little bit the course I'm going to lecture this summer and of course I will be talking about International Taxation because this is my subject and I think it will be interesting for you if you are interested in international issues and you deal with international economics because this will help you to make better decisions in your strategic projects. So I invite you to join this course, it will be dynamic. Of course we will be doing some lecturing but also some activities and well I think I will be able to get into the details of current international taxation which has really suffered a great revolution during the last 10 years. So you will be getting information about the international tax cooperation environment which is very interesting and also the involvement of developing countries which up until now in international taxation were not very relevant. So again I invite you to join the course, I hope you enjoyed and I hope to see you here in summer at Barcelona School at UBF.
