1 Nameplate Capacity is an estimate based on design capacity and normal operating efficiencies and does not necessarily represent maximum possible production.
2 The figures in this column reflect Alcoa’s share of production from these facilities.
3 Figures include the minority interest of Alumina Limited in facilities owned by AofA. From these facilities, Alcoa takes 100% of the production allocated to AofA.
4 The named company or an affiliate holds this interest.
5 In December 2008, approximately 15,000 mtpy annualized production was idled at the Portland facility due to overall market conditions. In July 2009, an additional 15,000 mtpy annualized production was idled, again, due to overall market conditions.
6 In Q1, 2010, the plant began restarting approximately 32,000 mtpy annualized production that was idled at the Poços de Caldas facility in 2009.
7 In November 2008, Baie Comeau permanently curtailed one potline (53,000 mtpy) in response to the economic downturn and as part of a modernization program, reducing nameplate capacity to 385,000 mtpy.
8 Owned through Rio Tinto Alcan Inc.’s interest in Pechiney Reynolds Québec, Inc., which is owned by Rio Tinto Alcan Inc. and Alcoa.
9 In November 2009, Alcoa announced the idling of smelting at Fusina and Portovesme due to uncertainty in obtaining competitively priced power and the financial impact of the European Commission decision regarding electricity tariffs,as described in Part I, Item 3. (Legal Proceedings) of this report. The idling of Portovesme has not occurred as of the filing of this report; Fusina is currently completely, but temporarily idled.
10 In March 2009, Alcoa and Orkla ASA exchanged respective stakes in the Sapa AB and Elkem Aluminium ANS companies. Alcoa now owns 100% of the Lista and Mosjøen smelters.
11 All production at the Tennessee smelter was idled in March 2009 due to economic conditions.
12 Between June and November 2008, three of Rockdale’s six potlines were idled as a result of uneconomical power prices.
The remaining three operating lines were idled in November 2008 due to uncompetitive power supply and overall market conditions.
13 Capacity at Intalco was restarted in Q1 2011. Currently, one half of one potline of Intalco’s three potlines, or approximately 47,000 mtpy, remains idled.
14 Capacity at Wenatchee was restarted in Q1 2011. Currently, one of Wenatchee’s four potlines, or approximately 43,000 mtpy, remain idled.
