valler, the company has to be aware of the two issues:
Gold vis a vis the USD and the USD vis a vis the kiwi.
They MUST hedge their gold in kiwi dollars, they are insuring against total catastrophe, if you consider this carefully a number of banks, insurance companies etc. etc. should have been so cautious. I hold OGC and I endorse their hedging policy which no doubt will be a function of their banking committments.
