Basis of presentation	1.Basis of presentation The accompanying unaudited condensed consolidated financial statements of Dollar General Corporation and its subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and are presented in accordance with the requirements of Form 10-Q and Rule 10-01 of Regulation S-X. Such financial statements consequently do not include all of the disclosures normally required by U.S. GAAP for annual financial statements or those normally made in the Company’s Annual Report on Form 10-K, including the condensed consolidated balance sheet as of January 30, 2015 which has been derived from the audited consolidated financial statements at that date. Accordingly, readers of this Quarterly Report on Form 10-Q should refer to the Company’s Annual Report on Form 10-K for the fiscal year ended January 30, 2015 for additional information. The Company’s fiscal year ends on the Friday closest to January 31. Unless the context requires otherwise, references to years contained herein pertain to the Company’s fiscal year. The Company’s 2015 fiscal year is scheduled to be a 52-week accounting period ending on January 29, 2016, and the 2014 fiscal year was a 52-week accounting period that ended on January 30, 2015. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the Company’s customary accounting practices. In management’s opinion, all adjustments (which are of a normal recurring nature) necessary for a fair presentation of the consolidated financial position as of October 30, 2015 and results of operations for the 13-week and 39-week accounting periods ended October 30, 2015 and October 31, 2014 have been made. The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The Company uses the last-in, first-out (“LIFO”) method of valuing inventory. An actual valuation of inventory under the LIFO method is made at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels, sales for the year and the expected rate of inflation or deflation for the year. The interim LIFO calculations are subject to adjustment in the final year-end LIFO inventory valuation. The Company recorded a LIFO provision (benefit) of $(1.7) million and $2.2 million in the respective 13-week periods, and $(2.3) million and $3.1 million in the respective 39-week periods, ended October 30, 2015 and October 31, 2014. In addition, ongoing estimates of inventory shrinkage and initial markups and markdowns are included in the interim cost of goods sold calculation. Because the Company’s business is moderately seasonal, the results for interim periods are not necessarily indicative of the results to be expected for the entire year. In May 2014, the Financial Accounting Standards Board (“FASB”) issued comprehensive new accounting standards related to the recognition of revenue, which specified an effective date for annual reporting periods beginning after December 15, 2016, with early adoption not permitted. In August 2015, the FASB deferred the effective date to annual reporting periods beginning after December 15, 2017, with earlier adoption permitted only for annual reporting periods beginning after December 15, 2016. The new guidance allows for companies to use either a full retrospective or a modified retrospective approach in the adoption of this guidance. The Company is currently evaluating these transition approaches, as well as the effect and potential timing of adoption on its consolidated financial statements. In April 2015, the FASB issued new accounting guidance related to the presentation of debt issuance costs and requires such costs to be presented as a deduction from the corresponding debt liability, consistent with the presentation of debt discounts and/or premiums. This guidance is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years, with early adoption permitted. The guidance must be applied retrospectively to all periods presented within the financial statements. The Company adopted this guidance in the third quarter of 2015, which resulted in the reclassification of $19.2 million and $15.5 million of debt issuance costs (net of accumulated amortization) from Other assets, net to Long-term obligations on the condensed consolidated balance sheets as of October 30, 2015 and January 30, 2015, respectively.

1.Basis of presentation

The accompanying unaudited condensed consolidated financial statements of Dollar General Corporation and its subsidiaries (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and are presented in accordance with the requirements of Form 10-Q and Rule 10-01 of Regulation S-X. Such financial statements consequently do not include all of the disclosures normally required by U.S. GAAP for annual financial statements or those normally made in the Company’s Annual Report on Form 10-K, including the condensed consolidated balance sheet as of January 30, 2015 which has been derived from the audited consolidated financial statements at that date. Accordingly, readers of this Quarterly Report on Form 10-Q should refer to the Company’s Annual Report on Form 10-K for the fiscal year ended January 30, 2015 for additional information.

The Company’s fiscal year ends on the Friday closest to January 31. Unless the context requires otherwise, references to years contained herein pertain to the Company’s fiscal year. The Company’s 2015 fiscal year is scheduled to be a 52-week accounting period ending on January 29, 2016, and the 2014 fiscal year was a 52-week accounting period that ended on January 30, 2015.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the Company’s customary accounting practices. In management’s opinion, all adjustments (which are of a normal recurring nature) necessary for a fair presentation of the consolidated financial position as of October 30, 2015 and results of operations for the 13-week and 39-week accounting periods ended October 30, 2015 and October 31, 2014 have been made.

The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

The Company uses the last-in, first-out (“LIFO”) method of valuing inventory. An actual valuation of inventory under the LIFO method is made at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels, sales for the year and the expected rate of inflation or deflation for the year. The interim LIFO calculations are subject to adjustment in the final year-end LIFO inventory valuation. The Company recorded a LIFO provision (benefit) of $(1.7) million and $2.2 million in the respective 13-week periods, and $(2.3) million and $3.1 million in the respective 39-week periods, ended October 30, 2015 and October 31, 2014. In addition, ongoing estimates of inventory shrinkage and initial markups and markdowns are included in the interim cost of goods sold calculation.
