Roles and responsibilities of audit committees

As an audit committee member, you have an essential role in contributing to your company’s success. Shareholders rely on your judgments as they make investment decisions. Your fellow board members depend on your insights as they consider the company’s risk landscape. Broader stakeholder groups, including regulators, management, employees, customers, and vendors, look to you to promote a culture of governance and compliance that can protect the company and enable it to thrive.

Your success in meeting this ever-expanding mandate requires a clear understanding of the audit committee’s roles and responsibilities. The latest edition of Deloitte’s Audit Committee Guide is intended to help you with this understanding.

While the guide is focused on requirements for US public companies, much of the content can be leveraged by those serving on nonpublic company audit committees.
