Intercompany transactions and balances have been fully eliminated in consolidation. Operating results for interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, certain components of equity, sales, expenses, and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ materially from these estimates. For further information, refer to the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 29, 2017. The Company utilizes a fifty-two, fifty-three week fiscal year ending on the Friday nearest December 31. The second quarter of 2018 and 2017 each contained 13 weeks and ended on June 29, and June 30, respectively. The Company’s 2018 and 2017 fiscal years will end or ended on December 28, 2018 and December 29, 2017, respectively.
