The contract with Heddle took longer than we expected. The delivery dates weren't being met. The work was being done and the work was generally being accepted, but at the end of the day, we had to do a very basic calculation. That is that the seaway closes on a given day and we needed the Hudson back on the east coast before the seaway closed. We did our best estimates of how to get that work done and we undertook action to accomplish that goal.
