pre_text: page 51 of 98 notes to consolidated financial statements ball corporation and subsidiaries 3 .
acquisitions ( continued ) effective january 1 , 2007 .
the acquisition has been accounted for as a purchase and , accordingly , its results have been included in the consolidated financial statements since march 27 , 2006 .
alcan packaging on march 28 , 2006 , ball acquired north american plastic bottle container assets from alcan packaging ( alcan ) for $ 184.7 million cash .
the acquired assets included two plastic container manufacturing plants in the u.s .
and one in canada , as well as certain manufacturing equipment and other assets from other alcan facilities .
this acquisition strengthens the company 2019s plastic container business and complements its food container business .
the acquired business primarily manufactures and sells barrier polypropylene plastic bottles used in food packaging and , to a lesser extent , barrier pet plastic bottles used for beverages and food .
the acquired operations formed part of ball 2019s plastic packaging , americas , segment during 2006 .
the acquisition has been accounted for as a purchase and , accordingly , its results have been included in the consolidated financial statements since march 28 , 2006 .
following is a summary of the net assets acquired in the u.s .
can and alcan transactions using preliminary fair values .
the valuation by management of certain assets , including identification and valuation of acquired fixed assets and intangible assets , and of liabilities , including development and assessment of associated costs of consolidation and integration plans , is still in process and , therefore , the actual fair values may vary from the preliminary estimates .
final valuations will be completed by the end of the first quarter of 2007 .
the company has engaged third party experts to assist management in valuing certain assets and liabilities including inventory ; property , plant and equipment ; intangible assets and pension and other post-retirement obligations .
( $ in millions ) u.s .
can ( metal food & household products packaging , americas ) alcan ( plastic packaging , americas ) .
post_text: the customer relationships and acquired technologies of both acquisitions were identified as valuable intangible assets by an independent valuation firm and assigned an estimated life of 20 years by the company based on the valuation firm 2019s estimates .
because the acquisition of u.s .
can was a stock purchase , neither the goodwill nor the intangible assets are tax deductible for u.s .
income tax purposes .
however , because the alcan acquisition was an asset purchase , both the goodwill and the intangible assets are deductible for u.s .
tax purposes. .
