Let me just start by saying that we engage with all of our suppliers in a very transparent and very clear way, and we are flexible, depending on the type of industry that our suppliers are engaged with. We also give reasonable notice to all of our suppliers related to the way we engage with them.
As you know, many of the fees that you just mentioned are related to the cost of doing business. Our business has evolved in many ways over the years, so we have evolved in the ways we have engaged with our customers by having these types of relationships. I would say that those fees normally go both ways, because our suppliers also have their own particular evolutions of their businesses, and we receive cost increases.
I think that we have a very transparent and very arm's-length relationship with them. In all cases, we are flexible, and we consider each of our particular situations with our suppliers based on a case-by-case basis.
