Abstract

This study aims to examine the effect of Good Corporate Governance on
Voluntary Disclosure. The company’s voluntary disclosure uses indicators
consisting of 3 categories: Strategic Information, Non Financial Information and
Financial Information. The Corporate Governance in this study uses 5 indicators,
namely the proportion of independent board of commissioners, the proportion of
independent audit committee, managerial ownership, institutional ownership, and
size of public accounting firm, and company size as control variable. By
proportional random sampling method, 70 annual reports of Indonesian
manufacturing companies were selected. Analytical tool to test the hypothesis is
multiple regression analysis using SPSS 16.0 program.
The results of this study indicate that the proportion of independent board of
commissioners, the proportion of independent audit committees, managerial
ownership, institutional ownership, and the size of public accounting firms
simultaneously affect voluntary disclosure. While in part, the results show that the
portion of the independent audit committee and the size of the public accounting
firm have a significant positive effect on voluntary disclosure. Institutional
ownership negatively affects voluntary disclosure. While the proportion of
independent board of commissioners, managerial ownership and firm size has no
significant effect on voluntary disclosure in the annual report.
