wembley losses plunge multiplex into red, page-2

"Chief executive Andrew Roberts described the Wembley losses as "extremely disappointing", but has promised that this will be the end of losses on the massive project."

How often do we hear that "_____x amount is the expected total losses" only for that figure to be 'revised' later on?

"Multiplex has now revealed the final losses from the project are STG183 million ($A434 million), before tax."

Does anyone else find it extremely disconcerting that they couldn't gauge the final figure for the project to within a near HALF BILLION dollars? What kind of fools undertook the cost & risk analysis for this project?
