Thank you very much, Mr. Chairman. Certainly awarding of contracts, not only in this department but in all the departments, are governed by our business incentive policy, and one of them is that as many companies say and do negotiate with local communities that they will use as much local and hire as much local as they can and that's their obligation and we do, as a department, monitor that and check on them. We do evaluate that, Mr. Chairman. Thank you.
