For the six months ended June 30, 2010, the Company treated the tax impact related to the following as discrete events for which the tax effect was recognized separately from the application of the estimated annual effective tax rate: (i) sale of the Mass Spectrometry division (ii) early extinguishment of debt; (iii) benefits relating to certain prior acquisitions; and (iv) the release of reserves for uncertain tax positions upon the completion of audits by tax authorities. The Company’s effective tax rate recorded for the six months ended June 30, 2010 was 14.7%. Excluding the impact of the discrete items discussed above, the effective tax rate would have been 24.8%. </div> </div>  <!-- Begin Block Tagged false false false us-types:textBlockItemType textblock Describes an entity's accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.
