Warren Buffett's Berkshire Hathaway ( BRKA) will buy Wal-Mart's ( WMT) grocery distribution unit for a little less than $1.5 billion. The purchase of McLane Co. comes as one of the industry's biggest players, Ahold NV's ( AHO) US Foodservice, is enmeshed in an accounting scandal. Buffett, whose reputation for above-board business dealing is as high as anyone's, said in a release announcing the deal that "there is an excellent possibility for expansion of the customer base in the future." McLane, based in Temple, Texas, contributed about $15 billion of sales to Wal-Mart last year. It is a wholesale distributor of groceries and other items to convenience stores, drug stores, wholesale clubs, mass merchandisers, restaurants, theaters and other outlets. It was acquired by Wal-Mart in 1990. As is his habit, Buffett will leave the acquired company's existing management in place. Wal-Mart also agreed to sell its Merit Distribution trucking unit to Swift Transportation ( SWFT), a Phoenix-based national truckload carrier. Excluding a one-time gain, the transaction will have a dilutive effect on Wal-Mart's earnings of about 1 cent a share in fiscal 2004 and about 2 cents in fiscal 2005.
