FISHMAN: Well, and if you just look at the last three years, in 2009 and 2010, Wal-Mart opened five stores a week every week in both those years. And then, last year, they opened a new store every day of the year, 366 new stores. BLOCK: These allegations detailed in the New York Times, if they're true, could amount to violations of federal law, the Foreign Corrupt Practices Act, and Wal-Mart apparently has told the Justice Department that it's conducting an internal investigation on that. Apart, though, from the criminal implications here, what about Wal-Mart's own ethical code? What did you learn from studying the company? FISHMAN: One of the reasons this is so surprising is precisely because Wal-Mart had a kind of unbending almost obsessive adherence to even the trivialist elements of an ethical code.
