[1] The contingent consideration represented the Company's best estimate, based on its review, at the time of purchase, of the underlying potential obligations estimated at a range of $8 million to $9 million, of certain Seller tax-related liabilities for which the Company has indemnified the Sellers as part of the purchase agreement. During the second and third quarters of 2012, the Company paid $3.7 million of additional purchase price related to the contingent consideration. The remaining liability range of $4.3 million to $5.3 million continues to represent the Company's best estimate of the remaining potential obligation at September 30, 2012.

[2] Consists of $33.0 million of customer relationships with an estimated 10 year useful life, $7.9 million of trademarks/trade names with an indefinite useful life and $7.5 million of technology and other intangible assets with an estimated 8 year useful life.

[3] All of the goodwill was assigned to the Company's Packaging reportable segment and is expected to be deductible for tax purposes.
