The life cycle on the label is basically four to five years, but obviously there are different stages in the process.
I think one of the most important things to agree on is the definition of the label; then, as it's utilized, it will mean the same thing to consumers. So when we talk about the transition to minimize the cost, in some cases, depending on where we are in the label changes, we could do so quickly. But we really want to know that when we do so it will be a common definition, clearly communicated, with a level playing field, and industry will be able to minimize the cost of doing it so that it will not be passed on to our consumers in providing them with the correct information.
