Important to note that a$0.60 is the max they can pay by passing on 100% franking credits. ($0.60 is mkt cap of $1.8b) It doesn’t mean that their HY profit is restricted to a$0.60 divided by payout ratio of say approx 0.70. It could very well be more... See below quote from CEO:

“Back in February Ms Gaines noted: “There’s no doubt that there’s been a lot of speculation about what might happen if there is a change in government and the impacts on franking credits. I think importantly Fortescue has a large franking balance, $1.8 billion before this dividend, so we’ve been a large taxpayer for a long period of time. We have seen the opportunity on the back of a strong performance, to accelerate the distribution of some of those franking credits to eligible shareholders. It probably has had some influence, but it also is on the back of that very strong operational performance and our strong position that we’re in as a business.”
