*CEO annual compensation is computed using the “options realized” and “options granted” compensation series for CEOs at the top 350 U.S. firms ranked by sales. The “options realized” series includes salary, bonus, restricted stock grants, options realized, and long-term incentive payouts for CEOs at the top 350 U.S. firms ranked by sales. The “options granted” series includes salary, bonus, restricted stock grants, value of options granted, and long-term incentive payouts.
**Annual compensation of the workers in the key industry of the firms in the sample.
***Based on averaging specific firm ratios and not the ratio of averages of CEO and worker compensation.

Notes: Projected value for 2017 is based on the change in CEO pay as measured from June 2016 to June 2017 applied to the full-year 2016 value. Projections for compensation based on options granted and options realized are calculated separately. “FH” denotes preliminary values from the “first half” of the year.
