The paper extends the ownership study by examining the different types of large shareholders in
relation to its impact on organizational outcome in Indonesia using a dataset consisting of 190
non-financial companies listed in Jakarta Stock Exchange in 2002. The study investigates the
effect of family ownership, foreign blockholder, domestic institutional shareholders, and the
board of directors on firm performance. The results confirm the different impact of different large
shareholders type on firm performance. Controlling family ownership is more likely to
exacerbate agency problems while the presence of foreign investor is related to superior firm
performance. Domestic blockholders is insignificantly related to firm performance. However, the
interaction effect between family and domestic blockholders ownership is negatively related to
firm performance, offering empirical evidence to the existence of interlocking blockholders in
Indonesia to deprive minority shareholders from their rights.
