* As of December 31, 2015, the amount reflected in Corporate is allocated to four of Alcoa’s five reportable segments ($146 to Alumina, $59 to Global Rolled Products, $253 to Engineered Products and Solutions, and $18 to Transportation and Construction 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 four reportable segments.
