Hi Little T , I believe we are on the same page - only difference is pre tax or post tax treatment.
If we take the after tax losses reported as per the Tax note 4 p35 :
US tax losses US $ 22.9m / .35 tax rate = US$65m
Aust tax losses US 2.4m /.30 tax rate = US $8m
Total pre tax losses available to offsett against future income $US73m approx
cheers
