January 2011Globalization, Governance, and the Returns to Cross-Border Acquisitions
with Jesse Ellis, Frederik P. Schlingemann, René M. Stulz: w16676
Using a sample of control cross-border acquisitions from 61 countries from 1990 to 2007, we find that acquirers from countries with better governance gain more from such acquisitions and their gains are higher when targets are from countries with worse governance. Other acquirer country characteristics are not consistently related to acquisition gains. For instance, the anti-self-dealing index of the acquirer has opposite associations with acquirer returns depending on whether the acquisition of a public firm is paid for with cash or equity. Strikingly, global effects in acquisition returns are at least as important as acquirer country effects. First, the acquirer's industry and the year of the acquisition explain more of the stock-price reaction than the country of the acquirer. Second, f...
September 2004Do Acquirers With More Uncertain Growth Prospects Gain Less From Acquisitions?
with Frederik P. Schlingemann, Rene M. Stulz: w10773
Behavioral finance models imply that an increase in shares outstanding leads to a lower stock price for firms with greater diversity in opinion among investors. Information asymmetry models imply that share issues by firms with greater information asymmetries are accompanied by larger share price decreases. Valuation models predict a negative relation between uncertainty resolution and share prices. Acquisition announcements are used to investigate these predictions. We find acquirer abnormal returns for acquisitions of public firms paid for with equity (but not for acquisitions of private firms paid for with equity) are lower for firms with higher dispersion of analyst forecasts, larger change in dispersion of analyst forecasts, and higher idiosyncratic volatility. The opposite result hol...

January 2004Wealth Destruction on a Massive Scale? A Study of Acquiring-Firm Returns in the Recent Merger Wave
with Frederik P. Schlingemann, Rene M. Stulz: w10200
Acquiring-firm shareholders lost 12 cents at the announcement of acquisitions for every dollar spent on acquisitions for a total loss of $240 billion from 1998 through 2001, whereas they lost $7 billion in all of the 1980s, or 1.6 cents per dollar spent. Though the announcement losses to acquiring-firm shareholders in the 1980s are more than offset by gains to acquired-firm shareholders, the losses of bidders exceed the gains of targets from 1998 through 2001 by $134 billion. The 1998-2001 aggregate dollar loss of acquiring-firm shareholders is so large because of a small number of acquisition announcements by firms with extremely high valuations. Without these announcements, the wealth of acquiring-firm shareholders would have increased. The large losses are consistent with the existence ...

March 2003Do shareholders of acquiring firms gain from acquisitions?
with Frederik P. Schlingemann, Rene M. Stulz: w9523
We examine a sample of 12,023 acquisitions by public firms from 1980 to 2001. Shareholders of these firms lost a total of $218 billion when acquisitions were announced. Though shareholders lose throughout our sample period, losses associated with acquisition announcements after 1997 are dramatic. Small firms gain from acquisitions, so that shareholders of small firms gained $8 billion when acquisitions were announced and shareholders of large firms lost $226 billion. We examine the cross-sectional variation in the announcement returns of acquisitions. Small firm shareholders earn systematically more when acquisitions are announced. This size effect is typically more important than how an acquisition is financed and than the organizational form of the assets acquired. The only acquisitions ...
