Based on the information I received and the short discussions I had with a couple of senior officials, the majority of the costs that they were able to identify were related to the translation of thousands of pages of documents. They said that the other costs would be very diffused and difficult to pinpoint, because they don't tend to track the activities of each and every one of their staff members.
This would have required a significant number of hours, but in the absence of a system that tracks by activity, they cannot estimate that precisely.
