Abstract
The major purposes of this study are two fold. First, we investigate whether or not the dilutive effect from stock options on the denominator of earnings per share is associated with the incurrence of stock repurchases. We use the FASB dilution and the economic dilution as the direct dilution measures and examine their relationship with stock repurchase decision. Second, we explore which of the extant measures of stock options can better explain the incurrence of stock repurchases. Six extant measures of stock options from previous studies are used: (1) the FASB's treasury-stock EPS dilution method, (2) the economic dilution measure based on Core, Guay and Kothari (2002), (3) the number of employee stock option exercises, (4) the number of stock option grants, (5) the number of total stock options outstanding, and (6) the number of exercisable stock options. Using a pooled cross-sectional sample from 1996–2000, we find a positive association between the likelihood of stock repurchases and the FASB dilution as well as the economic dilution in EPS, respectively. Thereby providing support for the undo-dilution hypothesis. The highest incremental explanatory power is found when we add the number of stock options exercisable to the baseline model. However, further analysis does not support the option-funding hypothesis suggested by Kahle (2002). We provide two explanations for why exercisable stock options better explain the stock repurchase decision.
