Mr. Chair, the way GST revenues work is that they are a function of consumption, they are a function of how much goods and services Canadians purchase.
In our budget, we looked at what we believed to be the consumption patterns of Canadians. We then made a mathematical equation against those consumption patterns, using the factor that we use for GST. The multiplication of the consumption patterns against the actual amount of GST results in a number, and that number was the number we used in our budget in order to provide what we saw as the forecast for GST revenues in the time period under question.
