Internal capital markets (ICMs) provide firms an alternative to costly external financing; however, they also provide an avenue to avoid the monitoring associated with issuing external capital. We argue that firms operating inefficient internal capital markets will avoid outside financing. Consistent with this view, conglomerates that cross-subsidize divisions or engage in value-destroying investment avoid external capital market oversight by refraining from issuing both debt and equity. We further show that firms issuing bonds while engaging in value-destroying investment experience yield spreads that are, on average, 46 basis points higher than those of other diversified firms. They similarly experience yield spreads that are 18 basis points higher when they issue syndicated loans. Value-destroying conglomerates also witness SEO announcement returns that are, on average, 1% more negative than firms operating more efficient internal capital markets.

In a large sample of shareholder initiated class action lawsuits from 1996 to 2011, we find a significant increase in informed insider option exercises during the class action period compared to the preceding quarter, and we find that this change is positively related to the probability of litigation. The market reaction to the announcement of lawsuits is negatively related to abnormal informed option exercises, but positively related to suits that ultimately get dismissed. These results suggest that the market can at least partially anticipate the merits and severity of the class action suit. In subsequent analyses, we find that CEO turnover is positively related to litigation, but not option exercises. Collectively, our results indicate that insiders knowingly trade on their private information.
