CEOs at large U.S. companies collectively realized at least $6 billion more in compensation than initially estimated in annual disclosures in the five years after the financial crisis first hit, according to a Reuters analysis. About 300 CEOs who served throughout the 2009-2013 period at S&P 500 companies together realized about $22 billion in compensation in the form of pay, bonuses and share and option grants, or an average of $73 million each, figures provided by executive compensation data firm Equilar show.
