Government Operations committee  It goes up and down. The $4 billion is actually calculated on a percentage basis. PW takes the total value of the inventory and applies a percentage to it to establish the recap rate, as they call it. That's why I say it's not a building-by-building calculation.

Government Operations committee  You would likely get a higher number. I don't think you'd get a lower one.

Government Operations committee  I can tell you that what has been looked at on the West Block are urgent health and safety concerns. You are on the Hill all the time, and you would have seen the scaffolding and netting. Costing is very hard to predict, given the age of those buildings and the unique work that needs to be done.

Government Operations committee  It's a bit of a case-by-case scenario. I know in some cases recently they've done triple net leases. I would caution you by saying that I am a taker on this. When they tell me it's triple net, they explain it to me. I'm not an expert in leasing, so they have to walk me through what this means.

Government Operations committee  And I haven't asked in every case whether this is triple or quadruple net.

Government Operations committee  Okay.

Government Operations committee  No.

Government Operations committee  Do you want me to answer that?

Government Operations committee  Precisely. Selling them and leasing does not mean Valhalla. There's a tremendous amount of work associated with lease management, lease negotiation, and then management of the ongoing contract renewals, and so on. There's no reason to believe that leasing will necessarily be the perfect solution.

Government Operations committee  That $4 billion figure, sir, relates to office buildings only. In one respect, it may be the tip of the iceberg. It doesn't tell you what the recapitalization outstanding costs are in terms of special purpose buildings.

Government Operations committee  No, sir, it's just relating to the—

Government Operations committee  It does not include crown corporate holdings and does not include recapitalization costs associated with special purpose space.

Government Operations committee  There is an annual exercise between the Treasury Board Secretariat and the Department of Public Works where Public Works comes to the secretariat and says--in very global terms, not building by building or issue by issue--that they have certain pressures on their accommodation budget that are what we call non-discretionary.

Government Operations committee  Remember, the sell and leaseback initiative, if that's what you're referring to, relates to nine buildings.

Government Operations committee  It would be much more than $26 billion, sir.
