It's probably not exactly the perfect term to have used. I can't remember exactly which budget it was, budget 2006 or budget 2005, in which the government announced that it was going to seek procurement savings from the procurement process as a result of different behaviours by Public Works, on the order of $1 billion, ramping up to about $1 billion per year. They were going to seek to reduce departments' A-bases by that amount proportionately, based on their actual procurement activity over a period of years. In that year, we expected to lose that amount from our A-base, but there was actually a later decision that year not to take that money away.
So tax is not quite the right term, but all departments that procure were expected to realize efficiency gains associated with that amount. It was returned to us, and that was the surprise.
