NEW YORK (AP) — Wal-Mart Stores Inc. gave its CEO Mike Duke a pay package in 2012 worth $20.7 million, a 14 percent increase from the year before, according to an Associated Press analysis of a regulatory filing Monday.

Duke’s performance-based cash bonus jumped more than 50 percent for a year that saw the world’s largest retailer posting strong financial results despite a challenging economy for its low-income shoppers.
