Ms Amy Ball:

It is a complex project. Overall, the benefit-cost ratio is 1.3:1, which means that the benefits are 1.3 times the costs. The total benefits amounted to €3.8 billion, while costs were €3 billion. I will ask my colleague Ms Smith to go through the detail to bring it to life a little more for the committee. I will be happy to go into the non-quantifiable aspects afterwards.
