Special responsibilities of the chairman

The evidence submitted by ASIC, accepted by the Court as disclosing a reasonable cause of action against Mr Greaves, provides an insight into the possible obligations in particular circumstances of the chairman of a board in light of s180(1). ASIC tendered affidavits from two prominent chairmen of listed public companies as expert opinion evidence, describing the role of a reasonably careful and diligent chairman of a listed company as follows:

the chairman must adopt a leadership role in the conduct of the board's responsibilities and lead and manage the board in the discharge of its duties;
this role includes setting the agenda for the performance of the board's responsibilities, taking steps to ensure board meetings take place with sufficient frequency, for a sufficient length of time and with adequate information and ensuring that the board is kept properly informed of the financial position and performance of the company;
the chairman leads the board in the monitoring of management, the assessment of the company's financial position and performance and the detection and assessment of any material adverse developments;
this involves directing, if so advised by the audit committee, and requiring, the provision of material financial information to enable the board to discharge its responsibilities;
it also involves taking steps to ensure that he or she and the board are informed as to the adequacy of the cash reserves of the company, including, especially where debtors outstanding are very substantial, an analysis of debtors including an aged listing;
if the chairman has an experienced financial background, the chairman should ensure that the person appointed as finance director has appropriate qualifications, expertise and experience;
the chairman will be concerned to be personally satisfied about the accuracy of public statements made on a company's behalf, and the company's compliance with the ASX Listing Rules;
where the business of the company is being established, and expenditure exceeds and is expected to continue to exceed income, the chairman will take a close and active interest in the cash reserves of the company, including the steps that should be taken to ensure that cash reserves are maintained so as to enable the company to pay its debts as and when they fall due;
if the company is in start-up phase, the chairman should also take steps to ensure that systems are implemented to properly monitor the cash flow in and out of the company and that he or she is promptly informed of any matters materially affecting the company's cash flow;
the chairman will take steps to ensure that there is an active and functioning audit committee, among other things to assess the general standards of performance of the financial system and management;
the chairman will take steps to ensure that the company has a process of ongoing internal audit review by an internal auditor.
