Basis of Presentation | Basis of Presentation The accompanying unaudited consolidated condensed 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 the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for a complete presentation of the financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation have been included in the accompanying financial statements. For further information, refer to the consolidated financial statements and footnotes included in the Company’s 2018 Form 10-K. As described in Note 2, the Company adopted ASU 2016-02, Leases, at the beginning of the first quarter of fiscal 2019. Under the modified retrospective method, comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. As described in Note 16, the Company realigned certain brands into a new operating segment during the first quarter of fiscal 2019. All prior period disclosures have been restated to reflect the new reportable operating segments.
Fiscal Year | Fiscal Year The Company’s fiscal year is the 52 or 53-week period that ends on the Saturday nearest to December 31. Fiscal years 2019 and 2018 both have 52 weeks. The Company reports its quarterly results of operations on the basis of 13-week quarters for each of the first three fiscal quarters and a 13 or 14-week period for the fiscal fourth quarter. References to particular years or quarters refer to the Company’s fiscal years ended on the Saturday nearest to December 31 or the fiscal quarters within those years.
Seasonality | Seasonality The Company’s business is subject to seasonal influences that can cause significant differences in revenue, earnings and cash flows from quarter to quarter; however, the differences have followed a consistent pattern in recent years.
