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 notes 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 notes included in the Company’s 2024 Form 10-K.
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 year 2025 has 53 weeks and fiscal year 2024 had 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 fourth fiscal 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 experiences moderate fluctuations in sales volume during the year, as reflected in quarterly revenue. The Company expects current seasonal sales patterns to continue in future years. The Company also experiences some fluctuation in its levels of working capital, typically reflecting an increase in net working capital requirements near the end of the first and third fiscal quarters as the Company builds inventory to support peak shipping periods. Historically, cash provided by operating activities is higher in the second half of the fiscal year due to collection of wholesale channel receivables and higher direct-to-consumer sales during the holiday season. The Company meets its working capital requirements through internal operating cash flows and, as needed, borrowings under its revolving credit facility, as discussed in more detail under the caption "Liquidity and Capital Resources" in Item 2: "Management's Discussion and Analysis of Financial Condition and Results of Operations". The Company's working capital could also be impacted by other events.
Impairment or Disposal of Long-Lived Assets, Policy | Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or an asset group may not be recoverable. Each impairment test is based on a comparison of the carrying amount of the asset or asset group to the future undiscounted net cash flows expected to be generated by the asset or asset group. If such assets are considered to be impaired, the impairment amount to be recognized is the amount by which the carrying value of the assets exceeds their fair value.
Inventory, Policy | Change in Accounting Principle During the third quarter of 2025, the Company changed its method of accounting for certain domestic inventory valued using the last-in, first-out (“LIFO”) method to the first-in, first-out (“FIFO”) i nventory valuation method. Inventory valued under the LIFO method represented approximately 23.0% and 23.8% of the Company’s total inventories as of December 28, 2024 and December 30, 2023, respectively. This change in accounting principle is preferable because it improves comparability with the Company’s peers, more closely resembles the physical flow of inventory, aligns with how the Company internally manages the business, and conforms all of the Company’s distribution warehouse inventory to the FIFO method of accounting. Additionally, the Company intends to make a change from LIFO to FIFO for our tax provision in accordance with IRS rules and regulations. The Company applied this change in inventory costing method by retrospectively adjusting its historical financial statements.
