For the period 1990 through 2016 median CEO pay grew by over 400 percent. If annualized CEO pay growth thus far in the current decade continues for the rest of the decade, the end-of-decade median CEO pay level will have increased by more than 500 percent over the median CEO pay in 1990. Median CEO pay has grown at a rate faster than the indices noted at the beginning of this Bulletin. As also noted in this Bulletin, numerous factors have contributed to this. The most important probably is the proxy statement disclosure of CEO pay starting in the 1930s. The increasing portion of long-term incentive awards as part of annual CEO pay and the decade-by-decade growth of the stock markets also have been significant factors. Such factors are likely to cause continuing increase in CEO pay for the foreseeable future.
