When showing constant dollar figures on GAAP and non-GAAP financial measures, the foreign exchange impact is calculated by using current foreign exchange rates and applying them to the prior period results. Unless otherwise stated, Adjusted EBITDA figures included in this presentation exclude the impact of special items as defined in our quarterly earnings releases. We also monitor earnings (defined as net income from continuing operations) before interest, taxes, depreciation and amortization (EBITDA) and adjusted EBITDA (EBITDA before the impact of special items) as a supplement to our GAAP measures.

The Net impact of uncertain tax positions increased the effective tax rate by 0.5% ($0.9 million). This increase is due to the support of higher revenues and the impact of recent acquisitions. The business could be impacted by unforeseen changes in market factors, which could impact our existing assumptions used in our impairment test.
