Our analysis is based on a comprehensive sample of 264 stock option exchanges announced between 2004 and 2009. For each exchange offer, we measure the degree of conformity to ISS’ guidelines by comparing the observed design to the set of restrictions required by ISS in order to receive a favorable voting recommendation. We then assess whether the degree of conformity with ISS voting criteria is related to subsequent firm performance and executive turnover.
Our analysis produces four important results. First, we find that the stock market reaction to the introduction of exchange plans is positive, but decreasing in the extent to which the exchange plan conforms to ISS guidelines. Second, we document that the increase in operating performance associated with introduction of exchange programs is a decreasing function of the degree of conformity with the ISS voting framework. Third, we show that firms with exchange plans that more closely follow ISS requirements experience higher executive turnover than firms with less restrictive plans.
Finally, patterns in insider trading activity during the months prior to the introduction of the exchange programs suggest that insiders‟ expectations about the effect of these programs are consistent with these results. Specifically, insiders are net buyers for firms conducting exchanges with positive performance consequences. These results are consistent with the conclusion that compliance with ISS guidelines on stock option exchanges limits the recontracting benefits of these transactions and are not value increasing for shareholders.
