The inaugural voting season for say-on-pay may be over, but the long war for better shareholder relations over executive pay is just beginning.

In the last proxy season, more than 276 companies in the Russell 3000 received negative recommendations from proxy advisory firm ISS Corporate Services. Of the 276 companies that suffered the bad marks, 36 of them flunked their say-on-pay advisory votes from shareholders—a 13 percent failure rate. Nay votes from the last proxy season signaled increased shareholder concerns over company pay practices.
