Company’s futurenon-U.S. operating results; the impact on demand for the Company’s products among the Company’s various market sectors from economic, sovereign and political uncertainties, particularly regarding the effect of new or proposed tariff or trade regulations; the effect on the Company’s financial results from the United Kingdom voting to exit the European Union; fluctuations in expenditures by the Company’s customers, in particular large pharmaceutical companies; introduction of competing products by other companies and loss of market share; pressures on prices from competitors and/or customers; regulatory, economic and competitive obstacles to new product introductions; other changes in demand for the Company’s products from the effect of mergers and acquisitions by the Company’s customers; increased regulatory burdens as the Company’s business evolves, especially with respect to the U.S. Food and Drug Administration and U.S. Environmental Protection Agency, among others; impact of the newly enacted tax reform legislation in the U.S.; shifts in taxable income in jurisdictions with different effective tax rates; the outcome of tax examinations or changes in respective country legislation affecting the Company’s effective tax rate; the effect of the adoption of new accounting standards; the ability to access capital, maintain liquidity and service the Company’s debt in volatile market conditions, particularly in the U.S., as a large portion of the Company’s cash is held and operating cash flows are generated outside the U.S.; environmental and logistical obstacles affecting the distribution of products and risks associated with lawsuits and other legal actions, particularly involving claims for infringement of patents and other intellectual property rights.

** The provision for income taxes for the three and nine months ended September 29, 2018 includes a $2 million expense and a $6 million expense, respectively, related to U.S. tax reform.

(a) Selling & administrative expenses include purchased intangibles amortization and litigation provisions. Research & development expenses include acquired in-process research and development.

(b) The purchased intangibles amortization, a non-cash expense, was excluded to be consistent with how management evaluates the performance of its core business against historical operating results and the operating results of competitors over periods of time.

(c) Restructuring costs and certain other items were excluded as the Company believes that the cost to consolidate operations and reduce overhead and certain other income or expense items are not normal and do not represent future ongoing business expenses of a specific function or geographic location of the Company.

(d) The pension expense associated with terminating a frozen defined benefit pension plan was excluded as the Company believes these expenses are not indicative of normal operating costs.

(e) Litigation provisions and settlement gain were excluded as these costs are isolated, unpredictable and not expected to recur regularly.

(f) The provision for income taxes for the three and nine months ended September 29, 2018 includes a $2 million expense and a $6 million expense, respectively, related to U.S. tax reform. The provisions include: (1) an adjustment to our 2017 year end accrual for the toll charge resulting from federal proposed regulations and other state guidance during the third quarter and (2) the tax that results from the change in foreign currency exchange rates on the earnings taxed on December 31, 2017 under the Tax Cuts and Jobs Act as compared with the foreign currency exchange rates on the date of distribution of assets into the U.S. The Company believes this expense is not indicative of the Company’s normal or future income tax expense.

(g) Certain income tax items were excluded as these non-cash expenses and benefits represent updates in management’s assessment of ongoing examinations or other tax items that are not indicative of the Company’s normal or future income tax expense.

(h) The non-cash expense associated with accelerating the vesting of certain stock awards was excluded as the Company believes these expenses are not indicative of normal operating costs.

(i) Acquired In-Process Research and Development was excluded as it relates to milestone payments associated with a licensing arrangement for mass spectrometry that the Company believes is unusual and not indicative of its normal business operations.

Constant currency growth rates are a non-GAAP financial measure that measures the change in net sales between current and prior year periods, ignoring the impact of foreign currency exchange rates during the current period. These amounts are estimated at the current foreign currency exchange rates and based on the forecasted geographical sales in local currency as well as an assessment of market conditions as of today and may differ significantly from actual results.

These forward-looking adjustment estimates do not reflect future gains and charges that are inherently difficult to predict and estimate due to their unknown timing, effect and/or significance.
