NEW YORK — John Menzer, vice-chairman of Wal-Mart Stores Inc. said he would be retiring from the retailer on March 1 with his “current responsibilities [to] be assumed by other leaders in the company,” the retailer said in a statement Friday. Lee Scott, president and chief executive officer, said Menzer “is probably best known for transforming Wal-Mart International into a well-organized, fast-growing and profitable business. But he is also a talented corporate strategist and I personally have found him to be a valued business counselor.” Menzer has been with the company since 1995.
