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 In February 2014, Alcoa announced that it will permanently shut down the Point Henry smelter. Management determined that the smelter has no prospect of becoming financially viable. The shutdown of the Point Henry smelter will be completed in August 2014.
4 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.
5 The named company or an affiliate holds this interest.
6 The Portland smelter has approximately 30,000 mtpy of idle capacity.
7 In 2013, Alcoa temporarily curtailed 34,000 mtpy at its Poços de Caldas smelter and 97,000 mtpy at its Alumar smelter. In the first quarter of 2014, management initiated the temporary curtailment of the remaining 62,000 mtpy at the Poços de Caldas smelter and an additional 85,000 mtpy at the Alumar smelter. The process of curtailing this additional capacity began in March 2014, resulting in 23,000 mtpy coming offline by the end of the 2014 first quarter. These curtailments are expected to be complete by the end of May 2014.
8 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.
9 Owned through Rio Tinto Alcan Inc.’s interest in Pechiney Reynolds Québec, Inc., which is owned by Rio Tinto Alcan Inc. and Alcoa.
10 The Portovesme smelter has been fully curtailed since the end of 2012; Alcoa will keep the smelter in restart condition through June 2014.
11 The Avilés and La Coruña smelters have approximately 60,000 mtpy of idle capacity combined.
12 The Rockdale smelter has been fully curtailed since the end of 2008.
13 The Intalco smelter has approximately 49,000 mtpy of idle capacity.
14 The Wenatchee smelter has approximately 41,000 mtpy of idle capacity.

As of March 31, 2014, Alcoa had approximately 675,000 mtpy of idle capacity against total Alcoa Consolidated Capacity of 3,953,000 mtpy.

In May 2013, Alcoa announced that management will review 460,000 mtpy of smelting capacity over a 15-month period for possible curtailment. This review is aimed at maintaining Alcoa’s competitiveness despite falling aluminum prices and will focus on the highest-cost smelting capacity and those plants that have long-term risk due to factors such as energy costs or regulatory uncertainty. As part of this review during the remainder of 2013, management initiated the permanent shutdown of 146,000 mtpy of combined capacity at the Baie Comeau smelter (see footnote 8 above) and the Massena East smelter, as well as a temporary curtailment of 131,000 mtpy of capacity (see footnote 7 above). All of these actions were completed in 2013.

During the first quarter of 2014, management initiated three additional actions resulting in the permanent shutdown of 274,000 mtpy of capacity and the temporary curtailment of 147,000 mtpy of capacity (see footnote 7 above). The permanent shutdowns are comprised of the remaining capacity (84,000 mtpy) at the Massena East smelter and the full capacity (190,000 mtpy) at the Point Henry smelter (see footnote 3 above). The remaining capacity of the Massena East smelter represented two Soderberg potlines that were no longer competitive. This shutdown was completed by the end of the 2014 first quarter. As a result, the Massena East smelter has been removed from the table above.
