Currency exchange ratesThe main reason that TV changed it's estimate of RP2 costs from $90 to $110M was that the Namibian dollar had risen sharply early last year. It has now retreated back to where it was. That means that the estimate could now be revised back to $90M. With inflation this could become $100M or $110M. The thing is that if it remains weak it could give TV a cushion against costs going higher than $110M. I wonder if TV has considered a two year currency hedge that could lock in the exchange rate while the Namibian dollar is weak. The West African Franc is also very weak now which should help with the inflation issue.
