While constant currency calculations are not considered to be an IFRS measure, we do believe these measures are critical to understanding our global revenue results and to compare with many of our competitors who report their financial results in U.S. dollars. Therefore, we are including this calculation for comparing IFRS revenue figures for comparable periods as well as for comparing non-IFRS revenue figures for comparable periods. All constant currency information is provided on an approximate basis. Unless otherwise indicated, the impact of exchange rate fluctuations is approximately the same for both the Company’s IFRS and supplemental non-IFRS financial data.

Information on Growth excluding acquisitions (“organic growth”)

In addition to discussing total growth, we also provide financial information where we discuss growth excluding acquisitions or growth on an organic basis as used alternatively. In both cases, growth excluding acquisitions have been calculated using the following restatements of the scope of consolidation: for entities entering the consolidation scope in the current year, subtracting the contribution of the acquisition from the aggregates of the current year, and for entities entering the consolidation scope in the previous year, subtracting the contribution of the acquisition from January 1^st of the current year, until the last day of the month of the current year when the acquisition was made the previous year.

Information on Industrial Sectors

Our global customer base includes companies in 12 industrial sectors: Transportation & Mobility; Industrial Equipment; Aerospace & Defense; Financial & Business Services; High-Tech; Life Sciences; Energy, Process & Utilities; Consumer Goods & Retail; Natural Resources; Architecture, Engineering & Construction; Consumer Packaged Goods & Retail and Marine & Offshore. Commencing in 2012 we implemented an industry go-to-market strategy with the dual objectives of broadening and deepening our presence in our largest industries as well as increasing the contribution from a diversified set of industrial sectors. “Diversification Industries” include: Architecture, Engineering & Construction; Consumer Goods & Retail; Consumer Packaged Goods & Retail; Energy, Process & Utilities; Finance Business Services; High-Tech; Life Sciences; Marine & Offshore; and Natural Resources. “Core Industries” include: Transportation & Mobility, Industrial Equipment, Aerospace & Defense and a portion of Business Services.

3DEXPERIENCE Licenses and Software Contribution

To measure the progressive penetration of 3DEXPERIENCE software, we utilize the following ratios: a) for Licenses revenue, we calculate the percentage contribution by comparing total 3DEXPERIENCE Licenses revenue to Licenses revenue for all product lines except SOLIDWORKS and acquisitions (“related Licenses revenue”); and, b) for software revenue, the Company calculates the percentage contribution by comparing total 3DEXPERIENCE software revenue to software revenue for all product lines except SOLIDWORKS and acquisitions (“related software revenue”).
