Okay. That authorization number then approves the purchase. There's a contracting department within Public Works. They issue a contract to the agency of record that Marc spoke about, which is the agency hired by the Government of Canada to execute most of its buys. I'm going to say 95% of all buys go through them for the purpose of getting volume discounts and that kind of thing. Then the buy is executed. The agency of record will provide information during the campaign about the results at the end of the campaign, and it's monitored, and changes are made accordingly.
That's basically how it works.
