NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. Basis of Presentation

The Condensed Consolidated Balance Sheets of Wal-Mart Stores, Inc. and its subsidiaries (the “Company”) as of April 30, 2007 and 2006, and the related Condensed Consolidated Statements of Income and Condensed Consolidated Statements of Cash Flows for the three-month periods ended April 30, 2007 and 2006, are unaudited. The Condensed Consolidated Balance Sheet as of January 31, 2007, is derived from the audited financial statements at that date.

In the opinion of management, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. Such adjustments are of a normal recurring nature. Interim results are not necessarily indicative of results for a full year.

The condensed consolidated financial statements and notes thereto are presented in accordance with the rules and regulations of the Securities and Exchange Commission and do not contain certain information included in the Company’s Annual Report to Shareholders for the fiscal year ended January 31, 2007. Therefore, the interim condensed consolidated financial statements should be read in conjunction with that Annual Report to Shareholders.

NOTE 2. Net Income Per Common Share

Basic net income per common share is based on the weighted-average number of outstanding common shares. Diluted net income per common share is based on the weighted-average number of outstanding shares adjusted for the dilutive effect of stock options and restricted stock grants. The dilutive effect of stock options and restricted stock was 6 million and 3 million shares in the first quarter of fiscal 2008 and 2007, respectively. The Company had approximately 54 million and 62 million option shares outstanding at April 30, 2007 and 2006, respectively, which were not included in the diluted net income per common share calculation because their effect would be antidilutive.

NOTE 3. Inventories

The Company values inventories at the lower of cost or market as determined primarily by the retail method of accounting, using the last-in, first-out (“LIFO”) method for substantially all of the Wal-Mart Stores segment’s merchandise inventories. The Sam’s Club segment’s merchandise and merchandise in our distribution warehouses are valued based on the weighted-average cost using the LIFO method. Inventories of foreign operations are primarily valued by the retail method of accounting, using the first-in, first-out (“FIFO”) method. At April 30, 2007 and 2006, our inventories valued at LIFO approximate those inventories as if they were valued at FIFO.

NOTE 4. Discontinued Operations

During fiscal 2007, the Company disposed of its operations in South Korea and Germany, which were included in our International segment. Consequently, the net losses and cash flow items related to these operations are presented as discontinued operations in our Condensed Consolidated Statements of Income and our Condensed Consolidated Statements of Cash Flows for all periods presented. Additionally, the asset groups disposed of are reported as assets and liabilities of discontinued operations in our Condensed Consolidated Balance Sheet as of April 30, 2006.

Included in discontinued operations as presented in the Company’s Condensed Consolidated Statement of Income for the quarter ended April 30, 2006, are net sales of $778 million and net losses of $45 million from our South Korean and German operations.

NOTE 5. Acquisitions

In February 2007, the Company announced the purchase of a 35% interest in Bounteous Company Ltd. (“BCL”). BCL operates 101 hypermarkets in 34 cities in China under the Trust-Mart banner. The purchase price for the 35% interest was $264 million. Also in February 2007, the Company paid $376 million to purchase a loan issued to the selling BCL shareholders that is secured by the pledge of the remaining equity of BCL. Concurrent with the initial investment in BCL, the Company entered into a stockholders agreement which provides the Company with voting rights associated with a portion of the common stock of BCL securing the loan, amounting to an additional 30% of the aggregate outstanding shares. Pursuant to the purchase agreement, the Company is committed to purchase the remaining interest in BCL on or before February 2010 subject to certain conditions. The final purchase price for the remaining interest will be approximately $320 million, net of loan repayments and subject to reduction under certain circumstances.

After closing on the acquisition, the Company began consolidating BCL using a December 31 fiscal year-end. The Company’s Condensed Consolidated Statement of Income for the quarter ended April 30, 2007 includes the results of BCL for the period commencing upon the acquisition of the Company’s interest in BCL and ending March 31, 2007. BCL’s results of operations were not material to the Company. Assets recorded in the acquisition were approximately $1.2 billion, including approximately $438 million in goodwill, and liabilities assumed were approximately $908 million. The consolidated financial statements of BCL as well as the allocation of the purchase price are preliminary.

NOTE 6. Long-term Debt

During the first three months of fiscal 2008, the Company issued $500 million of 5.000% Notes Due 2012, $1 billion of 5.375% Notes Due 2017 and $750 million of 5.875% Notes Due 2027. Beginning on October 5, 2007, the Company will pay interest on the notes of each series on April 5 and October 5 of each year. Interest started accruing on such notes on April 5, 2007. The 2012 notes will mature on April 5, 2012; the 2017 notes will mature on April 5, 2017; and the 2027 notes will mature on April 5, 2027. Additionally, the Company repaid $1.5 billion in principal for certain notes that matured during the first quarter of fiscal 2008.
