Forward-looking statements also may relate to strategies, plans and objectives for, and potential results of, future operations, financial results, financial condition, business prospects, growth strategy and liquidity, and are based upon financial data, market assumptions and management's current business plans and beliefs or current estimates of future results or trends available only as of the time the statements are made, which may become out of date or incomplete. Forward looking statements are inherently uncertain, and investors must recognize that events could differ significantly from our expectations.

*Discussion of Non-GAAP Measures The non-GAAP financial measures used in this release are utilized by management in comparing our operating performance on a consistent basis. We believe that these financial measures are appropriate to enhance the overall understanding of our underlying operating performance trends compared to historical and prospective periods and our peers. We believe that these measures provide important supplemental information to management and investors regarding financial and business trends relating to the Company's financial condition and results of operations as well as insight into the compliance with our debt covenants. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information calculated in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures. Our industry peers may provide similar supplemental non-GAAP information with respect to one or more of these measures, although they may not use the same or comparable terminology and may not make identical adjustments. A reconciliation of non-GAAP financial measures presented above to our GAAP results has been provided in the financial tables included in this press release. Organic Sales and Organic Sales Growth Organic Sales in this release are net sales excluding the impact of foreign currency translation. Organic Sales can be expressed as a dollar amount or a percentage rate when describing Organic Sales Growth. Non-GAAP Net Income, Non-GAAP Income From Operations, Non-GAAP Diluted Earnings Per Share, Non-GAAP Operating Income Margin, and Non-GAAP Diluted EPS Guidance Non-GAAP Net Income, Non-GAAP Income From Operations, Non-GAAP Diluted Earnings Per Share, and Non-GAAP Diluted Earnings Per Share Guidance exclude acquisition related amortization expense, acquisition related expense, acquisition related stock compensation expense, restructuring and consolidation costs, non-cash amortization of interest rate swap expense and other income or charges that management does not consider to be directly related to the Company’s core operating performance. Non-GAAP Diluted Earnings Per Share is calculated by dividing Non-GAAP Net Income by GAAP weighted average shares outstanding (diluted). Non-GAAP Operating Income Margin is calculated by dividing Non-GAAP Income From Operations by GAAP Net Sales. Non-GAAP Adjusted EBITDA Non-GAAP Adjusted EBITDA represents earnings before interest, taxes, depreciation, acquisition related amortization, acquisition related costs, restructuring costs, stock-based compensation, asset impairment and other income or charges that management does not consider to be directly related to the Company’s core operating performance. Non-GAAP Adjusted EBITDA Margin Non-GAAP Adjusted EBITDA Margin is calculated by dividing Non-GAAP Adjusted EBITDA by GAAP Net Sales. Non-GAAP Free Cash Flow Non-GAAP Free Cash Flow is calculated by deducting purchases of property, plant and equipment. Non-GAAP Adjusted Free Cash Flow Non-GAAP Adjusted Free Cash Flow is calculated by adding back the payment for the interest rate swap settlement to Non-GAAP Free Cash Flow. Non-GAAP Operating Working Capital Non-GAAP Operating Working Capital is calculated by deducting accounts payable from net trade receivables plus inventories. Net Debt Net Debt is calculated by subtracting cash and cash equivalents from total gross debt. Non-GAAP Free Cash Flow Conversion Non-GAAP Free Cash Flow Conversion is calculated by dividing GAAP Net Income by Non-GAAP Free Cash Flow.
