The Company discloses in this presentation the non-GAAP financial measures of adjusted income from operations, adjusted net income and adjusted diluted earnings per share. Each of these non-GAAP financial measures provide supplementary information about the impacts of acquisition and integration related expenses, foreign-exchange impacts on inter-company loans reorganizational and impairment charges. Over the past three years, we have completed six acquisitions, two of which were transformative for the Company. The costs we incurred in completing such acquisitions, including the amortization of intangibles and deferred financing costs, have been excluded from these measures because their size and inconsistent frequency are unrelated to our commercial performance during the period, and which we believe are not indicative of our ongoing operating costs. We exclude the impact of currency translation from these measures because foreign exchange rates are not under management’s control and are subject to volatility. Other non-operating charges such as, the write-off of our interest rate swap, are excluded as the charges on not indicative of our ongoing operating cost. We believe the presentation of adjusted income from operations, adjusted net income and adjusted diluted earnings per share provide useful information in assessing our underlying business trends and facilitates comparison of our long-term performance over given periods

We believe this presentation is commonly used by investors and professional research analysts in the valuation, comparison, rating and investment recommendations of companies in the industrial industry. We use this information for comparative purposes within the industry. Non-GAAP adjusted income from operations, is not a measure of financial performance under GAAP and should not be considered as a measure of liquidity or as an alternative to GAAP income from operations.

(b) Non-GAAP adjusted net income and adjusted diluted earnings per share, represents GAAP net income, adjusted to exclude the tax-affected effects of restructuring and impairment charges (related to plant closures and other charges incurred to implement our strategic goals, that do not necessarily represent a major strategic shift in operations), one-time charges related to acquisition and integration costs, amortization of intangibles costs for fair value step-up in values related to acquisitions and amortization of deferred financing costs, and foreign exchange gain (loss) on inter-company loans. We believe this presentation is commonly used by investors and professional research analysts in the valuation, comparison, rating and investment recommendations of companies in the industrial industry. We use this information for comparative purposes within the industry.
