Mr. Nicholas Tarrant:

In making the change in the second year of implementation, it was done with the best of intentions and with a view to implementing it correctly. When the change was made, the foresight was not there as to how it was going to impact with the other variables that change in the model over time. The change made in the second year was consistent with the approach that had been used in all the years up to the year that it was changed in the first year of the implementation of LEU rebalancing.
