The conference call did not say this, it said that the reference price was $1,045. If you go into the details it says that there was an agreed discount to the reference price. If you then work out the size of the sale and the overall price paid (which I assume is right) it divides through and the maths gives an uncannily even $100 discount to the average REFERENCE price of $1,045.
[e] I'm not in the slightest surprised that the IMF wanted to imply that India paid $1,045 an ounce. But unless the overall sale value is wrong (which I very much doubt), they didn't pay that at all.
