Maybe I can bring in a nuance in the analysis that was done. There are different types of public-private partnerships. You have those that include solely the design, construction and maintenance of the new infrastructure, for which there's a strong consensus that it's a good way to do a project like this.
Then there's the addition of the operation. In the model that we studied, we had a variety of models that included a public operator versus a private operator. That was part of the consideration.
