Perhaps I'll open, and then I'll turn to Mr. Orr to provide further details.
It is correct that the passport fund operates off a revolving fund. That means it essentially has a permanent authority that allows it to use its revenues against its expenditures and to carry forward any surpluses or deficits.
These estimates in 2016-17 were forecasting a net decrease in the surplus in the fund of $17.9 million. That's mostly due to the fact that we have a forecasted increase in terms of spending required to actually continue to support the modernization of the program and in terms of the various measures we're putting in place to ensure that the services are responsive to Canadians. Modernization spending compared to the previous year and other adjustments were related to the forecasted net revenues that come in as a result of passport fees.
I don't know, Bob, if you wanted to add to that.
