Note 1 – Basis of Presentation

Our consolidated financial statements include our accounts, as well as those of our wholly owned and majority owned subsidiaries. Certain prior period amounts have been reclassified to conform to the current period presentation.

Our accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnote disclosures required by U.S. GAAP for complete financial statements.

The consolidated financial statements reflect all adjustments considered necessary for a fair presentation of the consolidated results of operations and financial position for the interim periods presented. All such adjustments are of a normal recurring nature. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes to the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 30, 2017.

The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The results of operations for the nine months ended September 29, 2018 are not necessarily indicative of the results to be expected for any other interim period or for the year ending December 29, 2018.

On August 16, 2017, we announced that our Board of Directors approved a 2-for-1 split of our common stock. Each Henry Schein, Inc. stockholder of record at the close of business on September 1, 2017 received a dividend of one additional share for every share held. Trading began on a split-adjusted basis on September 15, 2017 and has been retroactively reflected for all periods presented in this Form 10-Q. As a result of the stock split, we increased our authorized common shares from 240,000,000 to 480,000,000, effective May 31, 2018.
