There are two things. The first is that we see a contribution of net exports to growth in 2011, but it's a modest contribution of 0.3% on a rate of growth of 2.3% in 2011. The second thing is yes, that will be sensitive. It's sensitive to productivity; it's sensitive to demand in the United States; it's also sensitive to currencies.
The reconciliation I would make is not to reconcile with the government's statement per se, but to reconcile with a different part of the press release that notes heightened tensions in global currency markets. This relates to the discussion we had earlier with Mr. Menzies on the efforts to resolve global imbalances. There are heightened tensions in global currency markets. That does create a risk for the Canadian economy and through the net export channel and back into the economy, including true confidence effects, as Mr. Wallace raised earlier. We are very alert to that and we do watch developments in these markets closely.
