It was a bad quarter from AGOs point of view considering they paid off $54m debt the previous quarter. What was the big difference between that quarter and this quarter? Tonnes shipped? Realised price? I know the didn't receive the headline high IO prices but surely they didn't forward hedged a price for the March quarter at a price less than the December quarter? I'm just struggling to understand how there was such a big difference between the 2 quarters when everything seemed to be in the same region, there or thereabouts
