The economics ot save Tiwai may stack up as what I have gathered from the news,(not always accurate) is there will be a direct loss of 1000 job and and a further loss of 1600 associated jobs plus the cost of connecting Manipuri to the national grid is put at $400m. At a guess i would say that the cost of the unemployment benefits and their administration would be north of $50m a year and add to that the clean up cost to the company of $200m a negotiated settlement should be achieved. The current statements by both sides I would think are hard line statements before any negotiations start behind closed doorsI would tend to agree that Tiwai is less tenable than the other two. That said it is something I wish could be retained rather than just shut down. Only three out of the top 10 major aluminium companies are not Chinese or Russian, that presents a significant risk if trade relations collapse and embargoes eventuate.
