IGO did not write off its investment in WSA. It wrote down two WSA assets which did not including its investment in PAN.
PAN was valued at $81 millionas part of the accounting for the acquisition, which was equivalent to 19 cents per share being the market value at the time of the acquisition.
IGO therefore must believe that the value of PAN is equal to or inexcess of 19 cents per share. Otherwise it would be taking an impairment charge.
