Basis of Presentation	Basis of Presentation Basis of Historical Presentation The unaudited interim condensed consolidated financial statements of AbbVie Inc. (AbbVie or the company) have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) have been omitted. These unaudited interim condensed consolidated financial statements should be read in conjunction with the company’s audited consolidated financial statements and notes included in the company’s Annual Report on Form 10-K for the year ended December 31, 2023. It is management’s opinion that these financial statements include all normal and recurring adjustments necessary for a fair presentation of the company’s financial position and operating results. Net revenues and net earnings for any interim period are not necessarily indicative of future or annual results. Certain other reclassifications were made to conform the prior period interim condensed consolidated financial statements to the current period presentation.
