Appendix 20
21 The Company discloses in this presentation the non-GAAP financial measures of adjusted gross margin, adjusted income (loss) from operations, adjusted EBITDA, adjusted EBITDA margin, adjusted net income (loss), adjusted net income (loss) per diluted share and free cash flow. Each of these non-GAAP financial measures provides supplementary information about the impacts of acquisition, divestiture and integration related expenses, foreign- exchange impacts on inter-company loans, reorganizational and impairment charges. The costs we incur in completing acquisitions, including the amortization of intangibles and deferred financing costs, and divestitures are excluded from these measures because their size and inconsistent frequency are unrelated to our commercial performance during the period, and 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 are excluded, as the charges are not indicative of our ongoing operating cost. We believe the presentation of adjusted gross margin, adjusted income (loss) from operations, adjusted EBITDA, adjusted net income (loss), adjusted net income (loss) per diluted share and free cash flow provides useful information in assessing our underlying business trends and facilitates comparison of our long-term performance over given periods. The non-GAAP financial measures provided herein may not provide information that is directly comparable to that provided by other companies in the Company's industry, as other companies may calculate such financial results differently. The Company's non-GAAP financial measures are not measurements of financial performance under GAAP and should not be considered as alternatives to actual income growth derived from income amounts presented in accordance with GAAP. The Company does not consider these non-GAAP financial measures to be a substitute for, or superior to, the information provided by GAAP financial results. (a) Non-GAAP adjusted gross margin represents GAAP gross profit, adjusted to exclude the effects of restructuring and integration expense and non-operational charges related to acquisition and transition expense. 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 gross margin 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 gross margin. (b) Non-GAAP adjusted income (loss) from operations represents GAAP income (loss) from operations, adjusted to exclude the effects of restructuring and integration expense; non-operational charges related to acquisition and transition expense, intangible amortization costs for fair value step-up in values related to acquisitions, non-cash impairment charges, and when applicable, our share of income from joint venture operations. 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 (loss) 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 (loss) from operations. (c) Non-GAAP adjusted EBITDA represents GAAP income (loss) from operations, adjusted to include income taxes, interest expense, write-off of unamortized debt issuance costs, interest rate swap payments and change in fair value, change in fair value of preferred stock derivatives and warrants, depreciation and amortization, charges related to acquisition and transition costs, non-cash stock compensation expense, foreign exchange gain (loss) on inter-company loans, restructuring and integration expense, costs related to divested businesses and litigation settlements, income from discontinued operations, and non-cash impairment charges, to the extent applicable. 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 EBITDA 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 (loss) from continuing operations. (d) This line item reflects the aggregate tax effect of all non-GAAP adjustments reflected in the respective table. The Company estimates the tax effect of the adjustment items identified in the reconciliation schedule above by applying the applicable statutory rates by tax jurisdiction unless the nature of the item and/or the tax jurisdiction in which the item has been recorded requires application of a specific tax rate or tax treatment. (e) Non-GAAP adjusted net income (loss) represents GAAP net income (loss) adjusted to exclude the tax-affected effects of charges related to acquisition and transition costs, foreign exchange gain (loss) on inter-company loans, restructuring and integration charges, amortization of intangibles costs for fair value step-up in values related to acquisitions and amortization of deferred financing costs, non-cash impairment charges, write-off of unamortized debt issuance costs, interest rate swap payments and change in fair value, change in fair value of preferred stock derivatives and warrants, costs related to divested businesses and litigation settlements, income (loss) from discontinued operations, and preferred stock cumulative dividends and deemed dividends. 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 e (loss) from segment 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 (loss) from continuing operations.
