Research limitations/implications – This research only takes some of the research and expects further research to sample that which is broad in vulnerable time study. And the research for measuring is limited, so it would add another variable to the equation in the future. Originality/value – The Audit Committee does not affect firm value. It is possible that the company only applies to comply with formal GCG. So the existence of the audit committee does not indicate an improvement in the company's performance.
