Per the offtake agreement with OHM:
Trade terms will include a provision in the first twenty-four months for payment to be made on delivery of parcel sizes as small as 1,000 tonne to Port Hedland, significantly reducing E25’s working capital requirements.

Would be more likely this to be activated with a laydown full stocked and agreement in place rather than half the ship still being transported at end of June 2020.

Could be a sign management is feeling the heat by wanting payment before onboard and need a positive cash flow quarter to give themselves some breathing space, if another two ships don't sail (not including the early July shipment) they have some serious issues.
