(Reuters) - Wal-Mart Stores Inc
Eduardo Solorzano will step down as president and chief executive of the unit, and will be succeeded by Enrique Ostale. Solorzano will remain as chairman of the board of directors at Wal-Mart de Mexico
The move comes as the world's largest retailer remains under fire following a New York Times report in April 2012 that said Wal-Mart had intentionally stifled an internal probe in 2005 into allegations that Walmex officials had paid bribes to help build stores in Mexico.
Solorzano, 55, became the CEO of Walmex in early 2005 and held that role until early 2010, when he became president and CEO of Walmart Latin America.
Solorzano's career at Walmex began in 1985. According to the Times and emails released by U.S. lawmakers on Thursday, Wal-Mart executives were made aware of alleged bribery in the fall of 2005.
Wal-Mart has said it is cooperating with the U.S. Justice Department, the U.S. Securities and Exchange Commission and Mexican authorities in their investigations of the bribery allegations.
The timing of Solorzano leaving the Latin America job had nothing to do with the investigation, the company said.
"He will remain as chairman of the Walmart de Mexico Board of Directors. The changes we're announcing today are just part of our normal process as we work to develop global talent," Wal-Mart said in a statement.
Wal-Mart shares edged up 27 cents to $68.63 on Thursday.
Ostale, 52, had been president and CEO of Walmart Chile, formerly known as D&S, and will take on his new role in Mexico City on March 1, Wal-Mart said. He will be responsible for operations in Argentina, Brazil, Chile, Costa Rica, El Salvador, Guatemala, Honduras, Mexico and Nicaragua, which include 3,832 retail units and 373,000 employees.
Walmex's chief operating officer, Gian Carlo Nucci, will replace Ostale as president and CEO of Walmart Chile. Nucci, 43, joined Walmex in 1993.
Ostale joined D&S in 1989, left in 2000 and returned in 2006. Wal-Mart bought D&S in 2009. Wal-Mart said Ostale was key in leading the transformation of D&S to Walmart Chile.
Ostale is set to become the fourth CEO of Walmart Latin America since that position was created in 2004.
Separately, Danish pension fund PFA Pension said it would no longer invest in Wal-Mart, saying the retailer does not meet its standards for workers' rights, citing recent events such as a protest by U.S. workers the day after Thanksgiving, the busy shopping day known as Black Friday.
PFA Pension said it would withdraw an investment of 50 million Danish kroner ($8.79 million). The fund said it had pulled out of its Wal-Mart investment in the past, but then bought back in as it started to see improvements.
