Maybe I could just add one point to amplify. There are some cases in projects where it makes a lot of sense to integrate maintenance and operations into the design and construction, and there are other projects where it does not. A really good example is that the Canada Line was a stand-alone transit line, and it made sense to integrate operations and maintenance with the contract; whereas the current project we're working on, the Evergreen Line, is part of a bigger system and it doesn't make sense to integrate maintenance and operations, so we have not. There are some cases where it makes sense and others where it does not, and that can be a driving factor.
