Ann: Trading Halt, page-13

Depends on the ruling, the ASX and the Company.

Under 17.1
ASX may grant a trading halt at the request of an entity.
ASX may require the request to be in writing.
ASX is not required to act on the entity’s request.
The entity must tell ASX each of the following.
• Its reasons for the trading halt.
• How long it wants the trading halt to last.
• The event it expects to happen that will end the trading halt.
• That it is not aware of any reason why the trading halt should not be granted.
• Any other information necessary to inform the market about the trading halt, or that ASX asks for.

Under 17.1.1
The length of the trading halt cannot exceed the period permitted under ASX’s Operating Rules.

Amended 11/03/04
Note: ASX Operating Rule 16.4.2 says, that a trading halt can be applied, for a period not exceeding the commencement, of normal trading on the second trading day, following the day on which it is requested.

Example: On a Monday afternoon a company tells ASX that it expects an important announcement to be made regarding a major acquisition. Owing to the status of negotiations it is uncertain whether the announcement will be made that day or the following day. The company asks for and is granted a trading halt. The trading halt will operate until the announcement is made or the commencement of trading on the Wednesday, whichever occurs sooner.
