That's a good question. Obviously when you sign for three years, you have no leverage with the landlord. If you sign a longer-term lease, in terms of the rental flow for that landlord it's more interesting, so then you can impose some of these conditions.
With respect to those buildings where we have longer-term leases, as we enter into them we are trying to influence the way the landlords, the owners, are looking at renovations and investments in the buildings and trying to push them toward the standards that we believe are important.
