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 This entity is part of the Alcoa World Alumina and Chemicals group of companies and is owned 60% by Alcoa and 40% by Alumina Limited.
4 The named company or an affiliate holds this interest.
5 This figure includes the minority interest of Alumina Limited in the Portland facility, which is owned by AofA. From this facility, Alcoa takes 100% of the production allocated to AofA.
6 The Portland smelter has approximately 30,000 mtpy of idle capacity.
7 This entity is owned 100% by Alcoa.
8 In 2013, Alcoa temporarily curtailed 34,000 mtpy at the Poços de Caldas smelter and 97,000 mtpy at the 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 and was completed by the end of May 2014. In the 2014 third quarter, an additional 12,000 mtpy was curtailed at the Alumar smelter.
9 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 2013, 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.
10 Owned through Rio Tinto Alcan Inc.’s interest in Pechiney Reynolds Québec, Inc., which is owned by Rio Tinto Alcan Inc. and Alcoa.
11 The Avilés and La Coruña smelters have approximately 64,000 mtpy of idle capacity combined.
12 On October 23, 2014, Alcoa signed a definitive agreement to sell its 50.33% ownership stake in the Mt. Holly smelter to Century Aluminum Company. The sale is subject to customary regulatory approvals and is expected to close by the end of 2014.
13 The Rockdale smelter has been fully curtailed since the end of 2008.
14 The Intalco smelter has approximately 49,000 mtpy of idle capacity.
15 The Wenatchee smelter has approximately 41,000 mtpy of idle capacity.

As of September 30, 2014, Alcoa had approximately 665,000 mtpy of idle capacity against total Alcoa Consolidated Capacity of 3,613,000 mtpy.

In May 2013, Alcoa announced that management would review 460,000 mtpy of smelting capacity over a 15-month period for possible curtailment. This review was aimed at maintaining Alcoa’s competitiveness despite falling aluminum prices and would 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 9 above) and the Massena East smelter in New York, as well as a temporary curtailment of 131,000 mtpy of capacity in Brazil (see footnote 8 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 8 above). The permanent shutdowns were 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 in Australia. 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. For the Point Henry smelter, management determined that the smelter had no prospect of becoming financially viable. The shutdown of the Point Henry smelter was completed in August 2014.

In the 2014 third quarter, management approved the permanent shutdown of the Portovesme smelter (150,000 mtpy) in Italy, which has been idle since November 2012. This decision was made because the fundamental reasons that made the Portovesme smelter uncompetitive remain unchanged, including the lack of a viable long-term power solution.

As a result, the Massena East, Point Henry, and Portovesme smelters have been removed from the table above.
