We investigate the impact of stock‐based compensation on managerial ownership. We find that equity compensation succeeds in increasing incentives of lower‐ownership managers, but higher‐ownership managers negate much of its impact by selling previously owned shares. When executives exercise options to acquire stock, nearly all of the shares are sold. Our results illuminate dynamic aspects of managerial ownership arising from divergent goals of boards of directors, who use equity compensation for incentives, and managers, who respond by selling shares for diversification. The findings cast doubt on the frequent and important theoretical assumption that managers cannot hedge the risks of these awards.

We examine the practice of resetting the terms of previously-issued executive stock options. We identify properties of reset options, develop a model for valuing resettable options, and characterize the firms that have reset options. We find the vast majority of options are reset at-the-money, resulting, on average, in the strike price dropping 40%. Our valuation model suggests that resetting has only a small impact on the ex-ante value of an option award, but the ex-post gain can be substantial. Finally, we find resetting has a strong negative relation with firm performance even after correcting for industry performance.
