Thank you for the question.
I'll try to give you a two-part answer. I'll start and then I'll ask my colleagues to respond.
For the first part, it's important to understand that McKinsey & Company was one of the five suppliers. To our minds, it was transparent. It wasn't just McKinsey & Company.
That was a decision we made in the context of benchmarking, which allowed us to use that method. At the contract stage, if the situation is unique, regulations allow for the establishment and use a special procurement method.
In a way, it's going to make it helpful to the suppliers and the clients to move expeditiously. If you know there's only one that can compete, you go there.
For the second part, I'll ask my colleague Mr. Laporte to take over.
