The primary purpose of this paper is to examine the relationship betwe
en firm performance and the proportion of shares owned by directors fo
r a sample of small and medium sized companies in the U.K. The paper a
lso examines, however, the impact of organisational form on firm perfo
rmance. The results suggest that, in contrast to the majority of large
firm studies on the subject, a curvilinear relationship is found to e
xist between firm performance and the percentage of equity held by the
board of directors. The return on assets of firms is found to increas
e as director ownership increases up to a maximum at 68.2% of ownershi
p, after which it then decreases as director ownership approaches 100%
of equity. In addition, the results suggest that firms whose director
s are more highly remunerated and who hold directorships in other comp
anies are significantly more profitable. Furthermore, firms in which t
he owners perceive present management practices to be lacking in struc
ture are found to have significantly lower performance.
