"Despite having demonstrated our ability to deliver operational profitability, it is clear from the deteriorating macro environment and the competitive pricing environment in certain regions challenging profitability that we must embark on a more aggressive transformation," ALU CEO Ben Verwaayen said in a statement.
ALU launched 'The Performance Programme' to achieve an additional Euro 750 million cost reduction, bringing total savings to Euro 1.25 billion by the end of 2013.

It could not be immediately ascertained whether the announcement will have any impact on its Indian unit.
"This is global headcount reductions plan. We will not comment at this time on where these reductions will be made. We will communicate more detail about this in September," an ALU spokesperson in India said.
