http://www.mysharetrading.com/what-difference-between-trading-halt-and-suspension-official-quotation.htm

Companies have to make announcements now and then. With the hustle (mostly) and bustle of the stock market, you may need more than the typical tapping on the glass to be heard. Companies have the option to temporarily suspend trades when they have an important announcement to make. This gives investors a breather to evaluate their trading options.

Suspension of Official Quotation

If the company cannot make the pending announcement following a trading halt, it will be suspended by the Australian Stock Exchange. The suspension will remain until the company can make the announcement.
