With regard to today's PBO report, we actually took some pride in the conclusions made by the PBO. It found that the government has continued to act in terms of this project on a commercial basis, and that the likely outcome is that the government is looking at a net present value for its efforts of about $600 million.
The report did talk about certain scenarios, future scenarios, that were tested. These are not necessarily the most likely scenarios. We would also debate some of those future assumptions lying behind the demand forecasts and the usage of the pipeline. Overall, we were comfortable with the PBO's methodology and certainly with its finding regarding the commerciality of the project.
