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. This production remains idled.
6 In August 2013, Alcoa initiated the temporary curtailment of 31,000 mtpy at its Poços de Caldas smelter and 97,000 mtpy at its São Luís (Alumar) smelter. This action was completed by the end of September 2013. An additional 3,000 mtpy was temporarily curtailed at the Poços de Caldas smelter by the end of 2013.
7 In mid-May 2013, in connection with the announcement of a revised modernization plan schedule for the Baie-Comeau smelter, Alcoa stated that it would permanently close the plant’s two Soderberg potlines. The closure, which was completed in August, involved 105,000 mtpy of capacity and was part of the 460,000 mtpy of smelting capacity Alcoa announced was under review in May 2013.
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 January 2012, as part of a restructuring of Alcoa’s global smelting system, Alcoa announced that it had decided to curtail operations at the Portovesme smelter during the first half of 2012. In March 2012, Alcoa decided to delay the curtailment of the Portovesme smelter until the second half of 2012 based on negotiations with the Italian government and other stakeholders. In the third quarter of 2012, Alcoa began the process of curtailing the Portovesme smelter, and it has since been fully curtailed as of November 2012 with all 150,000 mtpy idled. This action may lead to the permanent closure of the Portovesme facility; however, Alcoa will keep the smelter in restart condition through June 2014.
10 In January 2012, Alcoa announced its intention to partially and temporarily curtail its Avilés and La Coruña smelters. The partial curtailments were completed in the first half of 2012. As a result of a modification to the load interruptibility regime then in place in the Spanish power market, Alcoa restarted a portion (27,000 mtpy combined for Avilés and La Coruña) of the capacity previously curtailed in the first half of 2012 in order to meet the requirements of the modified interruptibility regime. 35,000 mtpy and 27,000 mtpy remain curtailed at Avilés and La Coruña, respectively.
11 In August 2013, Alcoa announced the permanent closure of one potline representing 41,000 mtpy at the Massena East facility. In addition, in January 2014, Alcoa announced the permanent shutdown and demolition of the remaining two potlines (capacity of 84,000 mtpy) that employ Soderberg technology at the smelter. The two Soderberg potlines will be fully shut down by the end of the first quarter of 2014.
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. In January 2012, Alcoa announced that it will permanently shut down and demolish two of the six idled potlines as part of a larger strategy to improve its cost position and competitiveness. The remaining four potlines (191,000 mtpy) remain idled.
13 Approximately half of one potline at the Intalco smelter remains idled, approximately 49,000 mtpy.
14 One potline at the Wenatchee smelter remains idled, or approximately 41,000 mtpy.

As of December 31, 2013, Alcoa had approximately 655,000 mtpy of idle capacity against total Alcoa Consolidated Capacity of 4,037,000 mtpy.

In June 2013, Alcoa announced its intention to permanently close the Fusina, Italy smelter. The closure is in addition to the 460,000 mtpy of operating smelting capacity that the company announced was under review in May 2013.
