Thank you, Mr. Chairman. On another issue -- I haven't finished with this budget area -- I know that there was some issue a while ago with the extension of the contract for air tankers and I know I have been pressing the Minister to do an RFP as soon as possible on that. I know the Minister had discussed at one point, because we had gotten to the point where we've gone past the deadline for the termination of one of the contracts. The Minister suggested that it was too late to go to an RFP right away but he could look at doing a short term extension in issuing an RFP to see what sort of prices we could get from Northern operators to deliver air tankers in a fairly short period of time. Why did the Minister choose to go with the five-year extension instead of the one or two-year extension?
