This presentation includes references to Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, Cash Flow Conversion, Lever age , Return on Invested Capital and Organic Net Sales, non - GAAP financial measures. These non - GAAP financial measures are used in addition to and in conjunction with results presented in accordance with GAAP. These meas ures are not intended to be substitutes for those reported in accordance with GAAP. Adjusted EBITDA and Free Cash Flow may be different from non - GAAP financial measures used by other companies, even when similar terms are used to identify such measures. EBITDA and Adjusted EBITDA are non - GAAP financial measures that comprise net income before interest, income taxes, depreciation and amortization, stock - based compensation, non - cash charges and certain other expenses. Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by net sales. The Company’s definition of Adjusted EBITDA may differ from similar measures used by other companies, even when similar terms are used to identify such measures. Adjusted EBITDA is a key metric used by management and the Company’s board of directors to assess financial pe rformance and evaluate the effectiveness of the Company’s business strategies. Accordingly, management believes that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as the Company’s management and board of directors. In order to provide investors with a meaningful reconciliation, the Company has provided reconciliations of Adjusted EBITDA to n et income. Free Cash Flow is a non - GAAP financial measure that comprises cash flow from operating activities less capital expenditures. Fre e Cash Flow is a measure used by management and the Company’s board of directors to assess the Company’s ability to generate cash. Accordingly, management believes that Free Cash Flow provides useful information to investo rs and others in understanding and evaluating our ability to generate cash flow from operations after capital expenditures. Cash Flow Conversion is a non - GAAP financial measure calculated as Cash flows from operations divided by Adjusted EBITDA. Leverage is a non - GAAP financial measure calculated as net debt divided by the trailing twelve months of Adjusted EBITDA. Net De bt is Total Debt and Finance Lease Obligations less Cash. Management believes leverage provides useful information to investors and others on our ability to fund our liquidity requirements. Return on Invested Capital (“ROIC”) is a non - GAAP financial measure defined as Adjusted EBITDA less Depreciation and Amortizatio n, which is then tax - effected at the Company's effective tax rate, which is then divided by average Invested Capital (Stockholders' Equity, Mezzanine Equity and Net Debt). Organic Net Sales is a non - GAAP financial measure that represents net sales excluding the impact of acquisitions and is intended to provide a meaningful comparison of sales growth attributable to underlying volume and pricing changes in the Company’s continuing operations.
