I'll turn the floor over to Mr. Orr, my colleague, but I'll just say that the passport program operates on a self-sustaining revolving fund, so the revenues, the fees that people pay, go into the revolving fund.
There is a business plan that operates over a 10-year period that takes into account the volumes. We try to forecast the volumes. It means that there are fluctuations in terms of the revenues that come in. The business plan also includes a strategy for investments to make sure that we're modernizing the passport system.
For example, we are migrating the passport program onto our global case management system. That requires certain investments, but it allows us to ultimately even go further in terms of online applications for passports. As I say, it also enhances the integrity by being able to actually put passports onto our global case management system and the synergies with, certainly, immigration as well in terms of citizenship.
I think that gives you an overview of the revolving fund. I'll turn it over to Mr. Orr for the specifics in terms of growth.
