Financial market integration and the value of global diversification: evidence from US acquirers in cross-border mergers and acquisitions

Bill B Francis, Iftekhar Hasan () and Xian Sun

Abstract: Using theories of internal capital markets, this paper examines the link between financial market integration and the value of global diversification. Based on a sample of 1,491 completed cross-border mergers and acquisitions (M&As) conducted by US acquirers during the 1990–2003 period, we find that, in general, US shareholders gain significant positive abnormal returns following the announcement of the merger/acquisition. Specifically, firms that acquire/merge with targets from countries with financially segmented markets experience significantly higher positive abnormal returns than those that acquire/merge with targets from countries with financially integrated capital markets. We find that the significantly higher positive returns are driven particularly by deals between firms from unrelated industries. These firms with higher announcement returns are also characterized by positive and significant post-merger operating performance. This finding is consistent with our event study results and suggests that the overall improvement in the merged firms’ performance is likely due to the influx of internal capital from wholly integrated acquirers to segmented targets, firms that, on average are usually faced with higher capital constraints.
