Additional important factors that could cause actual results to differ materially from those indicated by forward-looking statements include risks and uncertainties relating to: competition and its effect on pricing, spending, third-party relationships and revenues; the need to develop new products and adapt to significant technological change; implementation of strategies for improving growth; general worldwide economic conditions including economic conditions in the areas in which Thermo Fisher Scientific and Dionex sell products, and related uncertainties; dependence on customers' capital spending policies and government funding policies; the effect of exchange rate fluctuations on international operations; demand for analytical instrumentation; the effect of healthcare reform legislation; use and protection of intellectual property; the effect of changes in governmental regulations; and the effect of laws and regulations governing government contracts, as well as the possibility that expected benefits related to the transaction may not materialize as expected; the transaction not being timely completed, if completed at all; prior to the completion of the transaction, Dionex' business experiencing disruptions due to transaction-related uncertainty or other factors making it more difficult to maintain relationships with employees, licensees, other business partners or governmental entities; and the parties being unable to successfully implement integration strategies.

Use of Non-GAAP Financial Measures In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use certain non-GAAP financial measures, including adjusted EPS and adjusted operating income, which exclude restructuring and other costs/income and amortization of acquisition-related intangible assets. Adjusted EPS also excludes certain other gains and losses, tax provisions/benefits related to the previous items, benefits from tax credit carryforwards, the impact of significant tax audits or events and discontinued operations. We exclude the above items because they are outside of our normal operations and/or, in certain cases, are difficult to forecast accurately for future periods. We also use a non-GAAP measure, free cash flow, which excludes operating cash flows from discontinued operations and deducts net capital expenditures. We believe that the use of non-GAAP measures helps investors to gain a better understanding of our core operating results and future prospects, consistent with how management measures and forecasts the company's performance, especially when comparing such results to previous periods or forecasts.
