No. Actually, in the six scenarios we put forward around the wage, that was unrealistic. It was just to indicate the magnitude of the challenge. With regard to alternate-day delivery, I know Ernst & Young came out with saying that there would a small potential gain from that. I understand it's linked to the core infrastructure requirement and fixed-cost nature of the business.
In fact, some of the positives on the parcel side require some infrastructure investment, which means some of the savings will not necessarily pan out to the level we thought.
