It's now a voluntary suspension, which is different from a trading halt. A trading halt can only last 2 trading days. I previously posted that trading halts are quite common on the ASX, but voluntary suspensions are less so. Suspensions have some longer term implications, if they last for 5 days or more (as this one will). For example, their ability to issue new shares without a prospectus will be restricted for 12 months. Probably the least of their worries now, but companies generally don't go into a voluntary suspension lightly. In any case, it seems like they had no real choice - per ASX rules they had to either make an announcement this morning and resume trading, or request a suspension, and clearly there is no outcome to their discussions that they can announce yet.
