Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for fiscal year end consolidated financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. For further information, refer to the consolidated financial statements and related footnotes included in our Annual Report on Form 10-K for the fiscal year ended January 31, 2015 (Commission File No. 1-11084) as filed with the Securities and Exchange Commission on March 20, 2015.

Due to the seasonality of our business, results for any quarter are not necessarily indicative of the results that may be achieved for a full fiscal year.

We operate as a single business unit.

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in Accounting Standards Codification ("ASC") 605, Revenue Recognition. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the effective date of ASU 2014-09 for all entities by one year. The original ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Under the current pronouncements, we are required to adopt the new guidance in the first quarter of fiscal 2018 using one of two retrospective application methods. We are evaluating the application method and the impact of this new statement on our financial statements.

In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs (Subtopic 835-30). This ASU requires an entity to present such costs on the balance sheet as a direct deduction from the related debt liability rather than as an asset. We early adopted ASU No. 2015-03 during the quarter ended August 1, 2015 and applied it retrospectively. The early adoption resulted in the reclassification of debt issuance costs from other current and long-term assets to long-term debt on the balance sheet of $18 million as of October 31, 2015, $13 million as of January 31, 2015, and $14 million as of November 1, 2014.

To conform to the current year presentation, we have corrected the presentation of $43 million of deferred income taxes that were previously recorded as long-term other assets and $24 million of income taxes payable that were previously recorded as income taxes receivable as of November 1, 2014. We also corrected the presentation of $25 million of income taxes receivable that were recorded as current other assets as of January 31, 2015.
