The December 31, 2016, Condensed Consolidated Balance Sheet data was derived from audited financial statements, but does not include all annual disclosures required by GAAP. The above referenced financial statements included herein were prepared by management on the same basis as the Company's audited consolidated financial statements for the year ended December 31, 2016, and reflect all adjustments (consisting solely of normal recurring items unless otherwise noted) which are, in the opinion of management, necessary for the fair presentation of results of operations and cash flows for the interim periods ended September 30, 2017 and 2016, and the financial position of the Company as of September 30, 2017. Interim results may not be indicative of results for a full year. On January 31, 2017, the Company completed the acquisition (the "Esselte Acquisition") of Esselte Group Holdings AB ("Esselte"). Accordingly, the financial results of Esselte are included in the Company's condensed consolidated financial statements as of February 1, 2017, and are reflected in all three of the Company's reportable segments. See "Note 3. Acquisition" for details on the Esselte Acquisition. On May 2, 2016, the Company completed the acquisition of Australia Stationery Industries, Inc. (the "PA Acquisition"), which indirectly owned the 50% of the Pelikan Artline joint-venture and the issued capital stock of Pelikan Artline Pty Limited (collectively, "Pelikan Artline") that was not already owned by the Company. Prior to the PA Acquisition, the Pelikan Artline joint-venture was accounted for using the equity method. From the date of the PA Acquisition, which was May 2, 2016, the results of Pelikan Artline are included in the Company's condensed consolidated financial statements and are reported in the ACCO Brands International segment. Accordingly, we no longer separately report equity in earnings from this joint-venture. Effective with the first quarter of 2017, as a result of the Esselte Acquisition, the Company realigned its operating structure, which impacted its determination of its business segments for financial reporting purposes. As a result, the Company no longer reports the financial results of its Computer Products Group as a separate segment. Prior year amounts included herein have been restated to conform to the current year presentation. See "Note 15. Information on Business Segments" for details on the realigned segments. The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported assets and liabilities at the date of the financial statements and the reported revenues and expenses during the reporting periods. Actual results could differ from those estimates.
