Hi Luanboo, deferred settlement on the ASX just means that trades don't settle on the usual T+2 (two day) basis, they will settle on Wednesday the 19th of Dec. Settle of course means payment if you are the buyer and delivery of the share scrip if you are the seller. Deferred settlement trading is common in IPO's, spin offs, reconstructions, etc, anytime there is a "change" in the number of shares that shareholders own. It allows the stock to trade in the 10 days or so that it takes for the share register to process the "change", advise CHESS sponsors (ie. brokers) of the new holdings and mail out holding statements to shareholders.

An interesting element of this alluded to by other posters is that there will be little retail selling until holdings show up in broker accounts.
