This standard requires an acquiring company to measure all assets acquired and liabilities assumed, including contingent considerations and all contractual contingencies, at fair value as of the acquisition date. In addition, an acquiring company is required to capitalize IPR&D on its balance sheet at its acquisition date fair value. These IPR&D assets are accounted for as indefinite-lived intangible assets until the underlying project is completed. Once the project is completed, the carrying value of the IPR&D is amortized over the estimated useful life of the asset. If a project becomes impaired or abandoned, the carrying value of the IPR&D is written down to its fair value with the related impairment charge recognized in the period in which the impairment occurs. This accounting standard is applicable to acquisitions completed after January 1, 2009. Previous standards generally required post-acquisition adjustments related to business combination deferred tax asset valuation allowances and liabilities for uncertain tax positions to be recorded as an increase or decrease to goodwill. This new accounting standard does not permit this accounting and generally requires any such changes to be recorded in current period income tax expense. Thus, all changes to valuation allowances and liabilities for uncertain tax positions established in acquisition accounting, whether the business combination was accounted for under previous standards or under the newly issued accounting standard, will be recognized in current period income tax expense.In February 2009, the Company acquired all of the remaining outstanding capital stock of Thar Instruments, Inc. (“Thar”), a privately-held global leader in the design, development and manufacture of analytical and preparative supercritical fluid chromatography and supercritical fluid extraction (“SFC”) systems, for $36 million in cash, including the assumption of $4 million of debt. The acquisition of Thar was accounted for under the newly issued accounting standard for business combinations and the results of Thar have been included in the consolidated results of the Company from the acquisition date. The purchase price of the acquisition was allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values. The Company has allocated $24 million of the purchase price to intangible assets comprised of customer relationships, non-compete agreements, acquired technology, IPR&D and other purchased intangibles. These intangible assets are being amortized over a weighted-average period of 13 years. Included in intangible assets is a trademark in the amount of $4 million, which has been assigned an indefinite life. The excess purchase price of $22 million has been accounted for as goodwill. The goodwill is not deductible for tax purposes.In December 2008, the Company acquired the net assets of Analytical Products Group, Inc. (“APG”), a provider of environmental testing products for quality control and proficiency testing used in environmental laboratories, for $5 million in cash. This acquisition was accounted for under the purchase method of accounting and the results of APG have been included in the consolidated results of the Company from the acquisition date. The purchase price of the acquisition was allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values. The Company has allocated $3 million of the purchase price to intangible assets comprised of non-compete agreements, acquired technology, customer relationships and tradename. These intangible assets are being amortized over a weighted-average period of ten years. The excess purchase price of $1 million after this allocation has been accounted for as goodwill. The goodwill is deductible for tax purposes.In July 2008, the Company acquired the net assets of VTI Corporation (“VTI”), a manufacturer of sorption analysis and thermogravimetric analysis instruments, for $3 million in cash. This acquisition was accounted for under the purchase method of accounting and the results of VTI have been included in the consolidated results of the Company from the acquisition date. The purchase price of the acquisition was allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values. The Company has allocated $1 million of the purchase price to intangible assets comprised of a non-compete agreement and acquired technology. These intangible assets are being amortized over a weighted-average period of nine years. The excess purchase price of $2 million after this allocation has been accounted for as goodwill. The goodwill is deductible for tax purposes.The pro forma effect of the ongoing operations for Waters, Thar, APG and VTI as though these acquisitions had occurred at the beginning of the periods covered by this report is immaterial.6  Acquisitions Effective January 1, 2009, the Company implemented the newly issued accounting standard for business combinations.
