In terms of the challenge function and relating it to reallocations, as I understand it, what occurred was that there would have been a specific request for reallocations, and those specific requests would have undergone a challenge function. In the database I believe all they captured was whether a reallocation happened or not, and that's why we say that in terms of the reallocations in the database, they didn't capture the financial information related to each of those reallocations.
