This research aims to examine the effect of good corporate governance
mechanisms, the quality of external auditors and financial performance on firm value. In
this study the mechanism of good corporate governance is proxied by the proportion of
independent commissioners, managerial ownership, and institutional ownership. The
company value is proxied by the Price earnings ratio (PER). Financial performance is
proxied by Return On Assets (ROA) and Retun On Equity (ROE).
Sampling uses a purposive sampling method with the criteria of mining
companies that publish annual reports for the period 2012-2016 and have data relating to
the proportion of independent commissioners, managerial leadership, institutional
ownership, quality of external auditors, ret on assets, return on equity and PER. The
analytical method used is multiple linear regression.
The results of this study indicate that institutional ownership has a positive
effect on firm value, while the proportion of independent commissioners, managerial
ownership, the quality of external auditors, return on assets and return on equity does not
affect the firm's value.
