This presentation includes certain supplemental non-GAAP financial measures, that we believe are useful to investors as useful tools for assessing the comparability between periods as well as company by company. Our computation of these measures may not be comparable to other similarly titled measures computed by other companies. These non-GAAP financial measures should be considered in addition to, but not as a substitute for, our financial information and results prepared in accordance with U.S. GAAP included in our periodic filings made with the SEC. Further information relevant to the interpretation of non-GAAP financial measures, and reconciliations of these non-GAAP financial measures to the most comparable GAAP measures, may be found in the Appendix to this presentation.
