Unfortunately, in todays unethical environment, I would not trust an independent audit to do anything but to overstate by a wide marging the Central Bank holdings. Crooks of the worst sort. They will simply band together to move gold from one vault to another, and the same bullion would be counted numerous times. Same thing has been proven to happen at the ETFs, who count the same serialed numbered bars over and over again.
So who do you get to provide an honest count? Arthur Anderson?
