On the bids, yeah i agree you'd think they'd(coa board and mgmt) would be duty bound under 3.1(1) to keep the market fully informed of any information that may have a 'material impact' on the COA share price.

As for the price,$1.5b might be just equal to mkt cap,and you also have to include the HUGE debt overhanging COA, so then you are really looking something more closer approximately around the $2b mark implying a theoretical takeover value at the upper range of forecasts

However,given the current cyclical conditions and recent company performance,this really should imply a much lower offer provided the successful bidder(s) can extract the necessary synergies and greater work productivity improvements (than the current incumbents) in line with the future forecast cyclical conditions.
