After delivery, the settlement price of each grain contract is adjusted for:
- bulk handler receival fees
- shrinkage, and
- the applicable Grain Trade Australia (GTA) location differentials.
The Wheat Settlement Price also includes quality adjustments for protein content based on the grower receival stack averages (EC Wheat) or the average quality report by CBH nomination site (WA Wheat).
Note that the settlement price is not adjusted for grower levies – when selling through the ASX, growers are responsible for paying their own levy returns.
GTA location differentials
ASX Grains futures contracts are based on the GTA No 2 Contract. They are track contracts, requiring the grain to be delivered up-country within a certain specified price basing point (or port zone). The settlement price is calculated by subtracting the applicable GTA location differential at the time of the delivery from the track price.
