Thank you.
We will start the second part. It's 4:35, so we'll try to go to 5:35—although I understand we may have a vote on the extension of hours. We'll watch for that.
We have four to five witnesses. We have, first of all, from the Department of Finance, Ms. Lise Potvin, director of the sales tax division, tax policy branch; and Mr. Geoff Trueman, chief, air travellers security charge, sales tax division, tax policy branch. We have two gentlemen from the Department of Natural Resources: Mr. Howard Brown, ADM, energy policy sector; and Mr. Philip Jennings, director general, petroleum resources branch.
I apologize, but I don't have the other gentleman's name.
