[1] Property, plant and equipment are being depreciated on a straight-line basis over their preliminary estimated useful lives ranging from one to 40 years.
[2] Goodwill is calculated as the excess of the purchase price over the fair value of the net assets acquired. Goodwill generated from the acquisition is primarily attributable to expected synergies and the assembled workforce. Goodwill recognized in the transaction is deductible for tax purposes.
[3] We are amortizing intangible assets on a straight-line basis for customer relationships and trademarks over our preliminary estimates of their useful lives of 15 years and five years, respectively, in the Packaging segment.
