If I may also add that it's actually an excellent example of contract flexibility. I think there is a perception that we've put in place a contract that stays there and operates, when it's actually quite the contrary. We adapt them and change as circumstances arise or as what we're trying to incentivize changes.
In this instance, there were a lot of unexpected things that arose through the work and we had to adjust the contracts. It took some goodwill on both sides, if you will, to make sure that we still stayed on schedule and on budget.
