In 2011—I don't have the exact number here—approximately $3 million of a total of $36 million was government money, so funded sources.
For example, this money last year partly came from Los Angeles County's South Coast Air Quality Management District, which has a funding program to fund the development of cleaner technologies for trucks and buses and other equipment. So that's where some of that funding came from. As well, in the past we've received funding from the U.S. Department of Energy on deployment and demonstration projects.
So it comes from a myriad of sources, but the bulk of the funding, the lion's share of it, has been our shareholders' and our partners' investment, so private capital.
I can say that government funding does bring, when it comes to attracting new partners and bringing collaborative development programs like CN Rail, Gaz Métro, and the Electro-Motive project, a certain amount of cachet to the project. It also brings a certain rigour to the standards of the project in that there's an extensive evaluation process that really brings the best projects out.
