2015 Total Revenue Change – Third Quarter 7 October 20, 2015 (a) To calculate the FX impact, we first convert the current period’s local currency revenue using the average exchange rates fro m t he equivalent prior period to arrive at constant currency revenue. The FX impact equals the difference between the current period revenue in U.S. dollars and the cu rre nt period revenue in constant currency. (b) Net acquisitions revenue is the aggregate of the applicable prior period revenue of the acquired businesses. Netted against thi s number is the revenue of any business included in the prior period reported revenue that was disposed of subsequent to the prior period. (c) Organic revenue is calculated by subtracting both the net acquisitions revenue and the FX impact from total revenue growth. 3Q '14 FX Impact Net Acquisitions Organic Revenue 3Q '15 $3,750 $3,707 $(272) $1 $228 (b) (c) (7.2)% 0.0% 6.1% (a)

These measures exclude the recognition of an income tax benefit of $11.2 million related to expenses incurred in prior periods in connection with the pr opo sed merger with Publicis which was terminated on May 8, 2014. Prior to the termination of the merger, the majority of the merger costs, which were incurred in 2013, were capi tal ized for income tax purposes and the related tax benefits were not recorded. Because the merger was terminated, the merger costs were no longer required to be capitalized for in come tax purposes. We believe that investors should consider the “2014 Exclude Tax Benefit” measures as they are indicative of our ongoing performance and reflect how management evaluates our operational results. Non - GAAP financial measures should not be considered in isolation from or as a substitute for financial information presented in com pliance with U.S. GAAP. Non - GAAP financial measures reported by us may not be comparable to similarly titled amounts reported by other companies.

Non - GAAP Financial Measures We present financial measures determined in accordance with generally accepted accounting principles in the United States (“G AAP ”) 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 f rom, or as a substitute 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 b y other companies. We provide a reconciliation of non - GAAP measures to the comparable GAAP measures on pages 24, 25 and 26. The Non - GAAP measures used in this presentation include the following: 2014 Exclude Tax Benefit, which excludes the impact of the tax benefit related to expenses incurred in 2013 related to the proposed merger with Publicis which was terminated in 2014. We believe that this presentation allows for a more meaningful understanding of our performance. Net Free Cash Flow, defined as Free Cash Flow (defined below) less the Primary Uses of Cash (defined below). Net Free Cash Fl ow is one of the metrics used by us to assess our sources and uses of cash and was derived from our consolidated statements of cash flows. We believe that this presentation is meaningful for unde rst anding our primary sources and primary uses of that cash flow. Free Cash Flow, defined as net income plus depreciation, amortization, share based compensation expense less other non - cash items to reconcile to net cash provided by operating activities. Primary Uses of Cash, defined as dividends to common shareholders, dividends paid to non - controlling interest shareholders, capital expenditures , cash paid on acquisitions, payments for additional interest in controlled subsidiaries and stock repurchases, net of the proceeds and excess tax benefit from our stock plans, and excludes changes in wor king capital and other investing and financing activities, including commercial paper issuances and redemptions used to fund working capital changes. EBITDA, defined as operating income before interest, taxes, depreciation and amortization. We believe EBITDA is meaningful be cau se the financial covenants in our credit facilities are based on EBITDA. EBITA, defined as operating income before interest, taxes and amortization. We use EBITA as an additional operating performan ce measure, which excludes acquisition - related amortization expense, because we believe that EBITA is a useful measure to evaluate the performance of our businesses. Net Debt, defined as total debt less cash, cash equivalents and short - term investments. We believe net debt, together with the c omparable GAAP measures, reflects one of the metrics used by us to assess our cash management. After Tax Reported Operating Income, defined as reported operating income less income taxes calculated using the effective ta x r ate for the applicable period.
