You will forgive me if I respond in English.
It is not simply a question of putting a little logo on a bottle. If it were that easy, I think we would have probably done it a long time ago. There's reformulation that is required so that no- and low-calorie products, or specifically no-calorie products, can remain no-calorie products under rounding rules. There are nutritional facts panels. There are thousands of products, and both the primary package and the secondary package would have to be changed. Then we're talking about, I would estimate, approximately 100,000 vending machines in the country on which we have to physically change the buttons, as well as God knows how many pieces of fountain equipment we have to get to.
We're taking a tiered approach. You'll start seeing it on packaged products first. Hopefully we'll get to the packaged product, and then once that's done, we'll go out to fountain equipment, etc. Implementation is a significant undertaking that is costing many tens of millions of dollars.
That having been said, arriving at common serving sizes is a relatively short discussion in my sector, because we're a very homogeneous group. You asked me how quickly we could agree on a common serving size; that was a short conversation. It's all the other things that take the time.
