(St. Jude Medical or the Company) have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (U.S. generally accepted accounting principles) for complete financial statements. In the opinion of management, these statements include all adjustments (consisting of normal recurring adjustments) considered necessary to present a fair statement of the Company’s consolidated results of operations, financial position and cash flows. Operating results for any interim period are not necessarily indicative of the results that may be expected for the full year. Preparation of the Company’s financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts in the financial statements and footnotes. Actual results could differ from those estimates. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s consolidated financial statements and footnotes included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2011 (2011 Annual Report on Form 10-K). |
