Acquisitions And Divestitures
Acquisitions And Divestitures	E. Acquisitions and Divestitures – On March 9, 2011, Alcoa completed an acquisition of the aerospace fastener business of TransDigm Group Inc. for $240. This business is a leading global designer, producer, and supplier of highly engineered aircraft components, with three locations (one in the state of California and two in the United Kingdom) that employ a combined 400 people. Specifically, this business provides a wide variety of high-strength, high temperature nickel alloy specialty engine fasteners, airframe bolts, and slotted entry bearings. In 2010, this business generated sales of $61. The assets and liabilities of this business were included in the Engineered Products and Solutions segment as of March 31, 2011; this business' results of operations were included in this segment beginning March 9, 2011. Based on the preliminary purchase price allocation, goodwill of $213 was recorded for this transaction (amount deductible for income tax purposes is yet to be determined). In the second quarter of 2011, the initial goodwill amount was reduced by $53 due to purchase price allocation adjustments of the estimated fair value of the acquired business. The final allocation of the purchase price will be based on valuation and other studies, including environmental and other contingent liabilities, which are expected to be completed by the end of 2011. Other intangible assets may be identified as a result of the final valuation. This acquisition is part of a strategic plan to accelerate the growth of Alcoa's fastener business, while adding efficiencies, broadening the existing technology base, and expanding product offerings to better serve customers and increase shareholder value. Pro forma results of Alcoa, assuming this acquisition was made at the beginning of the earliest period presented, would not have been materially different from the results reported.
