 It was very important for us to attend that because it was a kind of milestone in the preparation of the World Cup 2022. And in this sense, Stadia made it possible to have a broad band audience and a lot of specialized carers attending the conference. It was possible to confront our point of views or experiences and in that sense to prepare for a better fine-tuned event in the future. The tourist component of the threat has become higher in the last years and for that we have to prepare in order to be sufficient resilient regarding this kind of threat. So to respond more precisely to a question, we are really facing a spontaneous threat that we didn't face in the past and this is why we have to prepare more for the domestic threat rather to tourism. And especially when you have crowded places, which is a case for major events like the future World Cup, we have to work on the best way to protect the security for those sites and this is what we do at Stadia today.
