Mr. Zuberi, thank you very much for your testimony.
I believe, Mr. Matthews, that to adequately respond would take you far beyond our allocated time. I would ask that, if you can, you provide to the best of your ability a fulsome answer for Mr. Zuberi and, once again, in writing to our clerk as quickly as possible.
We'll now go to Mr. Aboultaif for four minutes, please.
