Income Taxes	Income Taxes The Company has provided for potential tax liabilities due in the various jurisdictions in which the Company operates. Judgment is required in determining the worldwide income tax expense provision. In the ordinary course of global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of cost reimbursement arrangements among related entities. Although the Company believes its estimates are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in the historical income tax provisions and accruals. Such differences could have a material impact on the Company’s income tax provision and operating results in the period in which such determination is made. The Company's effective tax rate reflects the applicable tax rate in effect in the various tax jurisdictions around the world where its income is earned.
