Wal-Mart has removed same store sales as a metric on which managers and executives are measured for performance based compensation. As a result CEO Duke sees his compensation increase in the last fiscal year from what it would be under the previous arrangement. Same store sales have declined for seven consecutive quarters at Wal-Mart. The new metric used instead of same store sales is total sales, which increased 3.4% in the last fiscal year. Duke's compensation was $18.7 million, of which $16 million was performance based, for the last fiscal year. Morgenson asks if Wal-Mart executives are being opportunistic when it comes to setting the metrics for performance based compensation.
