(Reuters) - Wal-Mart Stores Inc said on Wednesday it will shrink its board by three members to 12, bringing it closer to U.S. corporate norms in a move the largest U.S. retailer hopes would allow it to respond more nimbly to rapid market changes.
The change will take place after Wal-Mart's annual shareholders' meeting on June 3, it said in a statement.
The revamp includes the retirement of Jim Walton, 67, the youngest son of late Wal-Mart founder Sam Walton, after 11 years on the board, the retailer said. His son Steuart, 34, has been nominated for a board seat.
Also departing are Aida Alvarez, a former member of U.S. President Bill Clinton's cabinet, retail industry veteran Roger Corbett, and Mike Duke, who was Wal-Mart's chief executive from 2009 to 2014.
Wal-Mart, which posted a double-digit profit decline last year as the dollar appreciated and costs rose as it hiked entry-level wages, said a smaller board would lead to better and faster decision-making.
The average board size for companies in the Standard & Poor's 500 index was 10.8 last year, according to the Spencer Stuart board index.
"The changes we are making are designed to maximize our effectiveness as we adapt to ever-evolving customer requirements," James Cash, lead independent director, said in the statement.
Both Alvarez, 66, a member of the auditing committee, and Corbett, 73, the former CEO of Australian retailer Woolworths Ltd, had been on the board for a decade, the normal tenure for independent directors, Wal-Mart said.
Duke's departure two years after leaving the CEO post is also in line with historical standards, it said.
Wal-Mart also said Wednesday that current CEO Doug McMillon's total compensation, including cash and stock, was valued at $19.8 million in the year ending Jan. 31, up from $19.4 million in 2014.
Last year, Wal-Mart's operating income fell 11 percent to $24.1 billion and sales dropped 0.7 percent to $482 billion, reflecting a $1 billion outlay to raise wages and the firmer dollar, which cut the value of overseas sales.
Excluding currency impacts, Wal-Mart's sales rose 2.8 percent to $499.4 billion.
Its core U.S. operations have shown some improvement, with sales at existing stores rising 1 percent last year, excluding fuel. Greg Foran, head of the U.S. business, saw his compensation fall to $11.5 million from $19.5 million, as his stock awards were lower after a big allocation last year due to his promotion.
