8 In May 2009, the Suralco alumina refinery announced curtailment of 870,000 mtpy. The decision was made to protect
the long-term viability of the industry in Suriname. The curtailment was aimed at deferring further bauxite extraction
until additional in-country bauxite resources are developed and market conditions for alumina improve. The refinery
currently has approximately 876,000 mtpy of idle capacity.
9 Reductions in production at Point Comfort resulted mostly from the effects of curtailments initiated in late 2008 through
early 2009, as a result of overall market conditions. The reductions included curtailments of approximately 1,500,000
mtpy. Of that original amount, 340,000 mtpy remain curtailed.
As of December 31, 2013, Alcoa had approximately 1,216,000 mtpy of idle capacity against total Alcoa Consolidated Capacity of 18,112,000 mtpy.
