* | As of December 31, 2013, $493 of the amount reflected in Corporate is allocated to three of Alcoa’s four reportable segments ($158 to Alumina, $61 to Global Rolled Products, and $274 to Engineered Products and Solutions) included in the table above for purposes of impairment testing (see Note A). This goodwill is reflected in Corporate for segment reporting purposes because it is not included in management’s assessment of performance by the three reportable segments.
