These presentation materials use the following financial measures that have not been calculated in accordance with generally accepted accounting principles (GAAP) accepted in the U.S., and therefore are referred to as non-GAAP financial measures:  Net sales at constant currency (organic sales)  Adjusted operating profit  Adjusted operating profit margin  Adjusted net income  Adjusted income tax expense  Adjusted diluted EPS  Net debt  Total invested capital  Net debt to total invested capital West believes that these non-GAAP measures of financial results provide useful information to management and investors regarding business trends, results of operations, and the Company’s overall performance and financial position. Our executive management team uses these financial measures to evaluate the performance of the Company in terms of profitability and efficiency, to compare operating results to prior periods, to evaluate changes in the operating results of each segment, and to measure and allocate financial resources to our segments. The Company believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in comparing its financial measures with other companies. Our executive management does not consider such non-GAAP measures in isolation or as an alternative to such measures determined in accordance with GAAP. The principal limitation of these financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management about which items are excluded. In order to compensate for these limitations, non-GAAP financial measures are presented in connection with GAAP results. We urge investors and potential investors to review the reconciliations of our non-GAAP financial measures to the comparable GAAP financial measures, and not to rely on any single financial measure to evaluate the Company’s business. Net sales at constant currency translates the current-period reported sales of subsidiaries whose functional currency is other than the U.S. dollar at the applicable foreign exchange rates in effect during the comparable prior-year period. In calculating adjusted operating profit, adjusted income tax expense, adjusted net income and adjusted diluted EPS, we exclude the impact of items that are not considered representative of ongoing operations. Such items generally include restructuring and related costs, certain asset impairments, other specifically identified gains or losses, and discrete income tax items. Please see “Financial Guidance” and “Non-GAAP Financial Measures” in the Company’s second-quarter 2017 earnings release for further information concerning reconciling items.
