It would take four to five years if you were starting from base one. That's the life cycle, but people are at different stages in it. We very recently went through a huge transition with the nutrition facts tables and other issues, and labels are in the process all the time. I'm not saying it will take four to five years to change, but you'd like to be able to get four to five years out of the label when it's out there and not be required to do significant changes for your product.
