AF4 used to be referred to as PF3.

The Company is interchanging the species of seafood and prawns at its various farms such that referring to each as “aquaculture farms (“AF”)” is now more accurate. Fish Farm 1 becomes AF1 and Prawn Farms 1 through 4 become AF2 - 5. These labels will be forthcoming in the Company’s financial reports and collateral material as the carve-out materializes.

I suspect it is nonsense.

Everyone suspects everything this company says is nonsense. That's why we're priced the way we are. But if you do a little due diligence there is usually an explanation for whatever questions you have.
