“…In relation to the 'diligence of the audit committee' , Spangler and Braiotta (1990) argue that the leadership and style of the audit committee chairperson is important, which complements McMullen and Raghunandan (1996) who argue that expertise in accounting, internal controls and auditing, as well as frequency of meetings, can contribute to audit committee effectiveness. What emerges from the audit committee literature is a focus on the structural characteristics of the committee acting as proxies for effectiveness, for example, independence, financial expertise and meeting frequency (Bedard and Grendron 2010), with a rarity of presentations of 'how' and 'why' between audit committee attributes and other variables (Turley and Zaman 2007). Recurring themes include: (1) audit committees are important mechanisms for strengthening governance; (2) governance reforms have sought to improve accountability and the integrity of financial reporting and performance reporting; (3) audit committees are a mechanism to enhance financial reporting and audit independence; and (4) audit committees, as agents of councillors, can be a mechanism for monitoring and protecting the interests of the community.…”
