Basis of Presentation	1. Basis of presentation — The unaudited interim consolidated financial statements included herein have been prepared by us pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”).

These financial statements include all adjustments, consisting only of those of a normal recurring nature, which, in the opinion of management, are necessary to present fairly the results of the interim periods presented and should be read in conjunction with the audited consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended June 30, 2019. The consolidated balance sheet at September 30, 2019 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and notes required by GAAP for complete financial statements.

We do not present a consolidated statement of comprehensive income as there are no other comprehensive income items in either the current or prior fiscal periods. The preparation of unaudited interim consolidated financial statements, in conformity with GAAP, requires us to make assumptions and use estimates that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates relate to: inventory valuation under the retail method and estimation of reserves and valuation allowances specifically related to insurance, income taxes and litigation.

Accounting Pronouncement Recently Adopted In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASC 842”). ASC 842 requires entities (“lessees”) that lease assets with lease terms of more than twelve months to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Under ASC 842, a right-of-use asset and lease liability is recorded for all leases, whether operating or finance, while the income statement will reflect lease expense for operating leases and amortization/interest expense for finance leases. In addition, ASC 842 requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. We adopted ASC 842 effective July 1, 2019 on a modified retrospective basis. We elected the transition option that allows entities to only apply the standard at the adoption date and not apply the provisions to comparative periods; therefore, prior periods were not restated. This transition option allows the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption rather than the earliest period presented. Our adoption of the standard resulted in a cumulative effect adjustment to retained earnings of $0.6 million, as of July 1, 2019. The adoption of the standard resulted in the recognition of operating lease assets of approximately $350 million and liabilities of approximately $375 million as of July 1, 2019. We elected certain practical expedients permitted under the transition guidance, including the package of practical expedients, which allows us to not reassess whether existing contracts contain leases, the lease classification of existing leases, or initial direct costs for existing leases. We elected not to separate lease and non-lease components for new and modified leases and not to recognize a right-of-use asset and a lease liability for leases with an initial term of 12 months or less. We did not elect the hindsight practical expedient. The adoption of the standard did not materially impact our consolidated net income or liquidity, and did not have an impact on debt-covenant compliance under our current debt agreements.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

1. Basis of presentation — The unaudited interim consolidated financial statements included herein have been prepared by us pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. These financial statements include all adjustments, consisting only of those of a normal recurring nature, which, in the opinion of management, are necessary to present fairly the results of the interim periods presented and should be read in conjunction with the audited consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended June 30, 2019. The consolidated balance sheet at September 30, 2019 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and notes required by GAAP for complete financial statements. For further information, refer to the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2019. The results of operations for the three month period ended September 30, 2019 are not necessarily indicative of the results to be expected for the full fiscal year ending June 30, 2020, which we refer to as fiscal 2020.

We do not present a consolidated statement of comprehensive income as there are no other comprehensive income items in either the current or prior fiscal periods.

The preparation of unaudited interim consolidated financial statements, in conformity with GAAP, requires us to make assumptions and use estimates that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates relate to: inventory valuation under the retail method and estimation of reserves and valuation allowances specifically related to insurance, income taxes and litigation. Actual results could differ materially from these estimates. Our fiscal year ends on June 30 and we operate our business as a single operating segment.

Accounting Pronouncement Recently Adopted

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASC 842”). ASC 842 requires entities (“lessees”) that lease assets with lease terms of more than twelve months to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Under ASC 842, a right-of-use asset and lease liability is recorded for all leases, whether operating or finance, while the income statement will reflect lease expense for operating leases and amortization/interest expense for finance leases. In addition, ASC 842 requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases.

We adopted ASC 842 effective July 1, 2019 on a modified retrospective basis. We elected the transition option that allows entities to only apply the standard at the adoption date and not apply the provisions to comparative periods; therefore, prior periods were not restated. This transition option allows the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption rather than the earliest period presented. Our adoption of the standard resulted in a cumulative effect adjustment to retained earnings of $0.6 million, as of July 1, 2019. The adoption of the standard resulted in the recognition of operating lease assets of approximately $350 million and liabilities of approximately $375 million as of July 1, 2019.

We elected not to separate lease and non-lease components for new and modified leases and not to recognize a right-of-use asset and a lease liability for leases with an initial term of 12 months or less.
