The accompanying unaudited condensed consolidated interim financial statements include the Company’s accounts and those of its wholly-owned subsidiaries, and reflect all adjustments which are necessary for a fair statement of the financial position, results of operations, and cash flows for the periods presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Such unaudited interim condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. These unaudited condensed consolidated interim financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2016 (“Annual Report”), and have been prepared on a consistent basis with the accounting policies described in Note 1 of the Notes to the Audited Consolidated Financial Statements included in our Annual Report. Our accounting policies did not change in the nine months ended September 30, 2017 , except for the new accounting pronouncements adopted as described in Note 2 — Recent Accounting Pronouncements . Seasonality of Business Due to the seasonal nature of our footwear, which is more heavily focused on styles suitable for warmer weather, the Company’s business is typically affected by seasonal trends, with higher wholesale sales in its first and second quarters and higher retail sales in its second and third quarters. In addition, our quarterly results of operations may fluctuate significantly as a result of other factors, including general economic conditions or consumer confidence. Accordingly, the Company’s operating results and cash flows for the three and nine months ended September 30, 2017 are not necessarily indicative of the operating results and cash flows for any other quarter or for the full year.
