The interim financial statements reflect all adjustments, which are, in the opinion of management, necessary for a fair presentation in conformity with GAAP. The interim financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company's annual report on Form 10-K for the fiscal year ended December 30, 2017, as filed with the Securities and Exchange Commission on February 27, 2018 (the “Fiscal 2017 Form 10-K”).

The results for the three and nine months ended September 29, 2018 and September 30, 2017 are each based on 13-week and 39-week periods, respectively. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the reporting period. Actual results could differ from those estimates. Except as noted below, the Company has considered all new accounting pronouncements and has concluded that there are no new pronouncements that may have a material impact on its results of operations, financial condition, or cash flows, based on current information. In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2016-02 (“ASU 2016-02”), Leases (Topic 842). ASU 2016-02 was issued by the FASB to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The Company has elected to adopt ASU 2016-02 in accordance with Accounting Standards Update No. 2018-11 (“ASU 2018-11”), Leases (Topic 842) Targeted Improvements. Under the transition method included in ASU 2018-11, the Company will initially apply ASU 2016-02 at the adoption date of December 30, 2018, which is the first day of Fiscal 2019, and will recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company’s reporting for the comparative periods presented in its financial statements will continue to be in accordance with previous GAAP (Topic 840, Leases). Under this transition method, the Company will provide the required Topic 840 disclosures for all periods that continue to be in accordance with Topic 840. The Company expects ASU 2016-02 will not have a material impact on its results of operations, however, this guidance will result in a significant increase to long-term assets and liabilities on the Company's balance sheet given the Company has a significant number of leases. The Company is in the process of implementing changes to its business processes, systems and controls to support the adoption of ASU 2016-02 in Fiscal 2019.

The results of operations for the interim periods should not be considered indicative of results to be expected for the full year.

The Company's fiscal year ends on the last Saturday in December. As used herein, the term "Fiscal Year" or "Fiscal" refers to a 52-week period, ending on the last Saturday in December. The results for the three and nine months ended September 29, 2018 and September 30, 2017 are each based on 13-week and 39-week periods, respectively.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the reporting period. Actual results could differ from those estimates.

Except as noted below, the Company has considered all new accounting pronouncements and has concluded that there are no new pronouncements that may have a material impact on its results of operations, financial condition, or cash flows, based on current information.

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2016-02 (“ASU 2016-02”), Leases (Topic 842). ASU 2016-02 was issued by the FASB to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The Company has elected to adopt ASU 2016-02 in accordance with Accounting Standards Update No. 2018-11 (“ASU 2018-11”), Leases (Topic 842) Targeted Improvements. Under the transition method included in ASU 2018-11, the Company will initially apply ASU 2016-02 at the adoption date of December 30, 2018, which is the first day of Fiscal 2019, and will recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company’s reporting for the comparative periods presented in its financial statements will continue to be in accordance with previous GAAP (Topic 840, Leases). Under this transition method, the Company will provide the required Topic 840 disclosures for all periods that continue to be in accordance with Topic 840. The Company expects ASU 2016-02 will not have a material impact on its results of operations, however, this guidance will result in a significant increase to long-term assets and liabilities on the Company's balance sheet given the Company has a significant number of leases. The Company is in the process of implementing changes to its business processes, systems and controls to support the adoption of ASU 2016-02 in Fiscal 2019.
