The foreign exchange rate impact is the difference between the current period revenue in U.S. Dollars and the current period constant currency revenue. (b) Acquisition revenue, net of disposition revenue: Acquisition revenue is calculated as if the acquisition occurred twelve mont hs prior to the acquisition date by aggregating the comparable prior period revenue of acquisitions through the acquisition date. As a result, acquisition revenue excludes the positive or negative difference between our current period revenue subsequent to the acquisition date and the comparable prior period revenue and the positive or negative growth after the acquisition date is attributed to organ ic growth. Disposition revenue is calculated as if the disposition occurred twelve months prior to the disposition date by aggregating the comparable prior period revenue of disposals through the dispo sit ion date. The acquisition revenue and disposition revenue amounts are netted in the presentation above. (c) Organic growth: calculated by subtracting the foreign exchange rate impact, and the acquisition revenue, net of disposition r eve nue components from total revenue growth.

You should carefully consider the foregoing factors and the other risks and uncertainties that may affect the Company’s business, including those described in Item 1A, “Risk Factors” in Omnicom’s Annual Report on Form 10 - K for the year ended December 31, 2018 and other documents filed from time to time with the Securities and Exchange Commission. Except as required under applicable law, the Company does not assume any obligation to update these forward - looking statements. Non - GAAP Financial Measures We present financial measures determined in accordance with generally accepted accounting principles in the United States (“GAAP ”) and adjustments to the GAAP presentation (“Non - GAAP”), which we believe are meaningful for understanding our performance. Non - GAAP financial measures should not be considered in isolation from, or as a su bstitute for, financial information presented in compliance with GAAP. Non - GAAP financial measures as reported by us may not be comparable to similarly titled amounts reported by other companies. We provide a reconciliation of non - GAAP measures to the comparable GAAP measures on pages 22 and 23 . The Non - GAAP measures used in this presentation include the following: Non - GAAP 2018 Adjusted results, including Adjusted Income Taxes and Adjusted Net Income - Omnicom Group Inc . , defined as our operating results excluding the impact of the income tax expense reduction related to the successful resolution of foreign tax claims , which was recorded in the first quarter of 2018 . We believe that this is a meaningful operating performance measure to understand the impact this item had on our reported results . Free Cash Flow, defined as net income plus depreciation, amortization, share based compensation expense plus/(less) other items to reconcile to net cash provided by operating activities. We believe Free Cash Flow is a useful measure of liquidity to evaluate our ability to generate excess cash from our operations. Primary Uses of Cash, defined as dividends to common shareholders, dividends paid to non - controlling interest shareholders, capi tal expenditures, cash paid on acquisitions, payments for additional interest in controlled subsidiaries and stock repurchases, net of the proceeds from our stock plans, and excludes changes in operating capital and o the r investing and financing activities, including commercial paper issuances and redemptions used to fund working capital changes. We believe this liquidity measure is useful in identifying the significant uses of our cash. Net Free Cash Flow, defined as Free Cash Flow less the Primary Uses of Cash. Net Free Cash Flow is one of the metrics used by us to assess our so urc es and uses of cash and was derived from our consolidated statements of cash flows. We believe that this liquidity measure is meaningful for understanding our primary sources and primary uses of that cash flow. EBITDA, defined as operating profit before interest, taxes, depreciation and amortization of intangible assets. We believe EBITDA is a meaningful operating performance measure because the financial covenants in our credit facilities are based on EBITDA. EBITA, defined as operating profit before interest, taxes and amortization of intangible assets and EBITA margin, defined as EBITA divided by revenue. We use EBITA and EBITA margin as additional operating performance measures, which excludes the non - cash amortization expense of intangible assets (primarily consisting of amortizatio n arising from acquisitions). Accordingly, we believe it is a useful measure for investors to evaluate the performance of our business. Net Debt, defined as total debt less cash, cash equivalents and short - term investments. We believe net debt, together with the comparable GAAP measures, reflects one of the liquidity metrics used by us to assess our cash management. After Tax Reported Operating Profit, defined as reported operating profit less income taxes calculated using the effective tax rate for the applicable period. Management uses after tax operating profit as a measure of after tax operating performance as it excludes the after tax effects of financing and investing activities on results of operations.
