Because we conduct business in over 120 countries, foreign exchange rate fluctuations may have a significant impact on our business. Foreign exchange rate movements may be significant and may distort true period-to-period comparisons of changes in revenue or pretax income.

The methodology used to calculate this comparable impact isolates the impact of the change in currencies between periods by hypothetically translating the prior year quarter’s revenue, expenses, and net income using the current quarter’s foreign exchange rates.
