Tunneling, Propping, and Expropriation: Evidence from Connected Party Transactions in Hong Kong

This working paper was written by Yan-leung Cheung (City University of Hong Kong), P. Raghavendra Rau (Purdue University) and Aris Stouraitis (City University of Hong Kong).We examine a sample of 328 filings of "connected transactions" between Hong Kong listed companies and their controlling shareholders during 1998-2000. We address three questions: What types of connected transactions are likely to lead to expropriation of minority shareholders? Which firms are more likely to expropriate? Does the market anticipate the expropriation? On average, firms earn significant negative excess returns both around the initial announcement of the connected transactions (from -2.5 per cent for firms making cash payments to directors to -5.9 per cent for firms selling equity stakes to their controlling shareholders) and during the 12-month period following the announcement (from -7.2 per cent for firms acquiring assets from their substantial shareholders to -21.9 per cent for firms selling assets to them). Excess returns are significantly negatively related to percentage ownership by the controlling shareholder. They are also significantly negatively related to proxies for information disclosure. The likelihood of undertaking connected transactions is higher for firms whose ultimate owners can be traced to mainland China. Finally, we find limited evidence that the market anticipates the expropriation by discounting firms that undertake connected transactions.
