As part of resetting the economic and fiscal framework in the budget, similar to how we do it in the fall update, we survey our group of private sector economists. The economic projections that underpin the budget are effectively a straight average of the group of 14 private sector economists.
To answer your question, in that group of economists, there's a broad range of different risk scenarios, and there's a broad range of factors that they include in their baseline forecast. For instance, when we surveyed this group of economists in December, leading to our preparation of the budget, about half of them anticipated successful passage of the U.S. tax reform plan, which came to fruition toward the end of the month. Likewise, there were a handful of economists who assumed some impacts with respect to the uncertainty around NAFTA trade negotiations.
All that considered, we take a straight average. There are the highs and the lows, but we take just a straight average, and build it into our forecast. Likewise, we include in this budget a bottom line risk adjustment, or a contingency, that manifests itself in terms of a $3-billion adjustment to the baseline forecast, again, to give ourselves some risk adjustment should we need it, which is considered prudent fiscal planning assumptions.
