Delivery Versus Payment (DvP) is a common settlement method that ensures shares are only delivered to an investor when payment has been secured. This form of settlement is effected by the ASX's CHESS system (Clearing House Electronic Sub-register System). It does this electronically by simultaneously transferring legal ownership of the shares with the transfer of funds. This is distinct from a 'manual' settlement where an investor will transfer funds to an issuer and receive shares direct from the registry.
DvP is designed to avoid settlement risk, where one party might fail to deliver on their side of the transaction.
