Non-GAAP Financial Disclosures

Financial information excluding the impact of certain significant items in this presentation are not measures that
are defined in U.S. Generally Accepted Accounting Principles (“GAAP”). These items are measures that
management believes are important to adjust for in order to have a meaningful comparison to prior and future
periods and to provide a basis for future projections and for estimating our earnings growth prospects. Non-
GAAP measures are used by management as a performance measure to judge profitability of our business
absent the impact of foreign currency exchange rate changes and acquisitions. Management analyzes the
company’s business performance and trends excluding these amounts. These measures, as well as EBITDA,
provide a more consistent view of performance than the closest GAAP equivalent for management and
investors. Management compensates for this by using these measures in combination with the GAAP
measures. The presentation of the non-GAAP measures in this presentation are made alongside the most
directly comparable GAAP measures.

Definition - Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA)

The sum of, net earnings and adding back provision for income taxes, interest expense, depreciations and
amortization expenses: this is a financial measure of the profit generated excluding the above mentioned
items.
