It's not that there are less taxes; it's that there are less taxes than were anticipated at the time of the fall update. There is a pullback in the forecast. Part of that is that corporate profits haven't quite played out, in terms of the profit track, as we thought they would in the fall. Likewise, this is usually the time of year where we get to call a number of corporations, namely banks and large resource companies, to get an understanding of how they're going to treat their 2017 tax returns, and more specifically how they're going to carry forward or carry back losses.
The corporate tax regime in Canada is very difficult. We have a very generous ability to take losses and apply them against previous year's taxable income or carry them forward into future years, thus forecasting corporate income taxes is incredibly difficult. Those two factors, the corporate profit track change between the fall update and the budget, and the anticipation of how the losses will be treated in the corporate sector, are what gave rise to the revision in budget 2018.
