3Alumínio is owned 100% by Alcoa.
4Brazilian mineral legislation does not establish the duration of mining concessions. The concession remains in force
until the exhaustion of the deposit. The Company estimates that (i) the concessions at Poços de Caldas will last at least
until 2020, (ii) the concessions at Trombetas will last until 2046 and (iii) the concessions at Juruti will last until 2100.
Depending, however, on actual and future needs, the rate at which the deposits are exploited and government approval is
obtained, the concessions may be extended to (or expire at) a later (or an earlier) date.

Onverdacht reserves were reclassified as resources pending testing during 2014 to confirm ore characteristics. Proven
reserves at Coermotibo were reclassified as probable reserves pending new density tests during 2014. Bauxite within
these areas will likely be exhausted in the next few years. During 2013, Suralco received for processing 12.7 thousand
