There was a very extensive process, an interdepartmental process, that came together to look at the second contract. So to answer the question directly, it wasn't simply a repackaging of the statement of requirements from the second contract, the 2002 contract, into the 2004 contract. There were new dimensions added to that contract, such as security requirements. So there was a very deliberate process in terms of what needed to be included in the contract going forward.
