INM has formally advised APN of its views and it is now seeking an extraordinary general meeting to allow all APN shareholders to express their views.
In a short statement to the Australian Stock Exchange, APN News and Media said: "APN is investigating these comments, but believes these comments arise from the fact that APN is considering a pro rata capital raising, in respect of which it is being advised by Macquarie Capital (Australia)."
APN News said the non-INM representative directors of APN unanimously supported Chenoweth and the strategy being implemented under his leadership.
The company said the reason for the trading halt is to prevent trading taking place in a speculative or uninformed market while APN investigates INM's comments and completes its deliberations about a potential capital raising.
It said the trading halt will remain in place until February 19.

In an earnings update released last December, APN News said its second half net profit would be affected by the deterioration of publishing revenue in Australia.
"Publishing in both Australia and New Zealand has seen weaker market conditions than in H1, with APN's publishing revenue in H2 down by 10 per cent," it said then.
