Firm characteristics and audit committees complying with ’best practice‘ membership guidelines

Abstract This study investigates demand and supply characteristics associated with firms that voluntarily established audit committees meeting ‘best practice’ membership guidelines. We focus on a set of best practice criteria rather than on the separate elements of the best practice criteria as in past studies. We conduct our tests using a sample of New Zealand listed companies that, relative to firms in other capital markets, are smaller and have more concentrated ownership. This setting differs from prior research because we expect the costs of voluntarily achieving best practice to be reasonably high. The results show that demand factors are not significantly related to the presence of an audit committee that conforms with best practice membership guidelines. However, supply factors (i.e. those firms with larger and more independent boards) are more likely to form audit committees that meet best practice. These results suggest that compliance costs will be greater for firms with smaller and less independent boards of directors if they are required to comply with best practice requirements.
