I think GX 100 is a good example. It shows how the railways can perform when there are penalties. What we're seeing is that when there are penalties, they're moving, and they're spotting it at a higher level. When there aren't penalties, they're not.
This is also illustrated by some of the other things CN does for other industries. For example, CN has CN tariff 9000 for other industries. This doesn't apply to grain, but in this tariff, CN has the guaranteed car order program, which provides for reciprocal penalties for non-performance. Customers can order the cars by day of the week up to four weeks out. Once these cars are accepted, CN pays the customer $100 per car, if the cars are not spotted on time, to the day of the week. The customer pays a penalty if the cars aren't used. As a result, they're performing in percentages that are in the high eighties and low nineties on these products.
