The data provisions were set up so we make sure we have sufficient time for the railways to submit the information to us, and then after we get that information to make sure there is sufficient time in the case of the performance data for the agency to post that data. Also, as part of the coming into force, we're providing the railways with one year to submit that data, simply because this is new data that they haven't been submitting. We need to make sure they have the system set up to provide us that data. It gave that amount of time for the railways to submit it.
