* As of December 31, 2012, $1,247 of the amount reflected in Corporate is allocated to each of Alcoa’s four reportable segments ($161 to Alumina, $751 to Primary Metals, $62 to Global Rolled Products, and $273 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 four reportable segments.

* In 2011, customer relationships were identified as an intangible asset ($31) related to the acquisition of an aerospace fastener business (see Note F) and were preliminarily classified as indefinite-lived in the table above. Upon the completion of the final valuation in 2012, it was determined that the customer relationships should have a finite life. As a result, the 2011 gross carrying amounts for indefinite-lived intangible assets and other intangible assets were revised to conform to the 2012 presentation.
