Statement Regarding Use of Non-GAAP Financial Measures

To supplement the consolidated financial results prepared in accordance with Generally Accepted Accounting Principles ("GAAP"), the Company uses certain non-GAAP historical financial measures. Management makes adjustments to the GAAP measures for items (both charges and gains) that (a) do not reflect the core operational activities of the Company, (b) are commonly adjusted within the Company's industry to enhance comparability of the Company's financial results with those of its peer group, or (c) are inconsistent in amount or frequency between periods (albeit such items are monitored and controlled with equal diligence relative to core operations) ("Non-GAAP Purposes"). The Company uses the term "Non-GAAP" to exclude certain expenses, gains and losses to achieve the Non-GAAP Purposes, including external acquisition-related costs incurred to effect a business combination; amortization of intangible assets acquired in a business combination, asset purchase transaction or other contractual relationship; impairment of goodwill and intangible assets; certain in-process R&D charges; fair value adjustments to contingent consideration liabilities and pre-acquisition contingencies arising from a business combination; integration and transition costs related to business combinations; fair market value adjustments to inventories acquired in a business combination or asset purchase transaction; restructuring charges, duplicative operating expenses, or asset write-offs (or reversals) associated with exiting or significantly downsizing a business; unusual non-recurring expenses associated with inventory write-downs; gain or loss from the sale of a business; gain or loss on the mark-to-market adjustment, impairment, or sale of long-term investments; mark-to-market adjustments on derivative instruments that hedge income or expense exposures in a future period; significant legal litigation costs and/or settlement expenses or proceeds; legal and other associated expenses that are both unusual and significant related to governmental or internal inquiries; expenses, acceleration of amortization of debt issuance costs and gain or loss on debt extinguishment associated with the exchange or redemption of convertible senior notes; significant discrete income and other tax adjustments related to transactions as well as changes in estimated acquisition-date tax effects associated with business combinations, and the impact from implementation of tax law changes and settlements; and any other adjustment that is determined to be appropriate and consistent with the Non-GAAP Purposes. See "GAAP to Non-GAAP Reconciliations" for a reconciliation of each non-GAAP measure presented to the comparable GAAP financial measure.

In addition, in order to remove the impact of fluctuations in foreign currency exchange rates, the Company also presents certain net sales information on a constant currency basis, which represents the outcome that would have resulted had exchange rates in the current period been the same as the average exchange rates in effect in the comparable prior period. See "Reported Sales vs. Prior Periods" for a presentation of certain net sales information on a reported, GAAP and a constant currency basis.
