Firms with more intangible assets are more likely to repurchase shares and have more positive repurchase announcement returns, as predicted. Because intangibles generally are unrecognized, share repurchases represent a potential cost to an incomprehensive accounting model. Idle cash is positively related to repurchase likelihood and negatively related to announcement returns, as predicted. Contrary to predictions, general information asymmetry is negatively related to repurchase likelihood, but announcement returns are positively related, as predicted. Tests include controls for stock option plans, dividends, and book-to-market ratios, which generally are significant as predicted. Using change variables in the repurchase likelihood tests yields consistent inferences.
