Using data from the 1998 proxy season, we find that higher levels of potential dilution from management-sponsored, executive-only stock option plans result in significantly negative cumulative abnormal returns in the 3-day period surrounding the proxy date. We also present evidence of a significantly negative relationship between the percentage vote against the option proposal and the percentage change in executive pay from the 1998 to 1999 compensation years. We interpret this finding to support the idea that boards of directors are responsive to shareholder concerns about CEO option awards following a high level of shareholder opposition.
