Supplemental
Non-U.S. GAAP Financial Information
U. S. GAAP – Non-U.S. GAAP
Reconciliation
The supplemental non-U.S. GAAP information presented in this press release is unaudited and subject to inherent limitations. Such non-U.S. GAAP information is not based on any comprehensive set of accounting rules or principles and should not be considered as a substitute for U.S. GAAP measurements. Also, our supplemental non-U.S. GAAP financial information may not be comparable to similarly titled non-U.S. GAAP measures used by other companies. Further, specific limitations for individual non-U.S. GAAP measures, and the reasons for presenting non-U.S. GAAP financial information, are set forth in the paragraphs below. To compensate for these limitations, the supplemental non-U.S. GAAP financial information should not be read in isolation, but only in conjunction with our consolidated financial statements prepared in accordance with U.S. GAAP.
The Company believes that these non-U.S. GAAP financial measures provide useful information for investors and management because they offer, when read in conjunction with the Company’s U.S. GAAP financials, (i) the ability to make more meaningful period-to-period comparisons of the Company’s on-going operating results, (ii) the ability to better identify trends in the Company’s business and perform related trend analysis, and (iii) to facilitate a comparison of the Company’s results of operations against investor and analyst financial models and valuations, which may exclude these items.
Net Financial Position ( non-U . S . GAAP measure )
Net Financial Position, a non-U.S. GAAP measure, represents the difference between our total liquidity and our total financial debt. Our total liquidity includes cash and cash equivalents, restricted cash, if any, short-term deposits, and marketable securities, and our total financial debt includes short-term debt and long-term debt, as reported in our Consolidated Balance Sheets.
We believe our Net Financial Position provides useful information for investors and management because it gives evidence of our global position either in terms of net indebtedness or net cash by measuring our capital resources based on cash and cash equivalents, restricted cash, if any, short-term deposits and marketable securities and the total level of our financial debt. Our definition of Net Financial Position may differ from definitions used by other companies, and therefore, comparability may be limited.
