Good corporate governance requirements.

f) Describe good corporate governance requirements relating to director’s responsibilities (e.g. for risk management and internal control) and the reporting responsibilities of auditors. [1]
I have written the following answer for the directors one but cannot find the auditors one would you like to justify my answer and suggest on good corporate governance requirements relating to auditor’s responsibility. Thank you.

The UK Corporate Governance Code is underpinned by the principles of all good governance: transparency, accountability and probity. It identifies good governance relating to various areas of director’s responsibilities such as;
Risk management and internal control: the board should at least, annually, conduct a review of the effectiveness of the company’s risk management and internal control systems and should report to shareholders that they have done so. The review should cover all material controls, including financial, operational and compliance controls.
Audit committee and auditors: the board should establish an audit committee with a balanced structure to ensure transparency. It suggests the committee should comprise at least three or in the case of small companies at least two independent non-executive directors.
