Unless otherwise stated, Adjusted Operating Income, Adjusted EBITDA and Adjusted EPS figures included in this presentation exclude the impact of special items as defined in our quarterly earnings releases. However, these impacts have moderated as of late. 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.
