pier 1, explorator andium. -- exploratorium. we stay in close contact with our tenants and that seems to be the right formula. >> questions? >> in terms of the cost estimates, as a requirement for reasonable expenses as opposed to reimbursement, do we have any way of analyzing the expenses, confirming whether they are reasonable or not? >> well, these are estimates that actually came from a consultant. we got the same estimates it from our internal analysis. >> i guess we're under a scenario where we would have to reimburse a tenant for their "reasonable" expenses. who makes that determination? if the tenedos overboard -- if a tenant goes overboard in their costs, what would we fall on with that? >> they have to prove their expenses, and we would go through those expensive and fine them to be reasonable or unreasonable. if they were unreasonable, we might approve some, not all. in this is where we have a grievance that could actually go to the relocation board, which is an active part of the rent control board in san francisco.
