Thank you, Mr. Chairman. We have two basic types of arbitration. We have one category we call expedited arbitration, which is for simpler cases where we try to group a number of arbitration cases together and have them held expeditiously by a single arbitrator. Then there are full arbitration cases which are usually the more complex ones. They vary quite substantially, from ones that we can get done in a few hours to ones that will take several days to work through. So there is no real norm, it really depends on the facts of the case.
