Overview of NAO

1.1 Overview of the NAO

The National Audit Office (NAO) is an independent public body established by the Constitution of the Republic of Mauritius. The Director of Audit is the head of the NAO and his appointment, independence, security of tenure, as well as his authority are spelt out in the Constitution while his duties and powers are laid down in the Finance and Audit Act.

In the international forum, NAO is referred to as the Supreme Audit Institution (SAI) of Mauritius. SAIs around the world are affiliated to the International Organisation of Supreme Audit Institutions (INTOSAI), an autonomous, independent and non-political organisation, which operates as an umbrella organisation for the external government audit community.

NAO forms an integral part of the governance system of Mauritius, promoting accountability, transparency and contributing to the improvement in the management of public funds. Public sector entities are accountable to the National Assembly for the use of public resources and powers conferred on them.

It is the responsibility of NAO to give independent assurance to the National Assembly and other oversight bodies that the public sector entities are operating and accounting for their performance in accordance with the purpose intended by the National Assembly. NAO, thus, plays a vital role in the accountability cycle.

1.2 NAO in the Accountability Process

The demand for public accountability on the part of the persons or entities managing public resources has become increasingly prominent over the years, such that, there is greater need for the accountability process in place to operate effectively. In Mauritius, the key stakeholders exercising financial control over public resources are:
● National Assembly
● Government Executives (Accounting Officers)
● Accountant-General
● National Audit Office (Director of Audit)
● Public Accounts Committee

The part played by these stakeholders in the accountability process is briefly described below:

National Assembly
  The only authority for the expenditure of public funds and for the raising of revenues by public bodies is that which is given by Parliament through the National Assembly. The National Assembly approves the Government Annual Estimates and this approval is given statutory force by the passing of an Appropriation Act each year, whereby the amount allocated for each Government service is set out under a series of “Votes”. Subsequently, the Appropriation Act is assented by the President of the Republic of Mauritius and gazetted.

Accounting Officers
  The Accounting Officers of Ministries and Government Departments are mainly the Senior Chief Executives, Permanent Secretaries and Administrative Heads. They are responsible for the efficient and effective management of funds entrusted to them, the collection of revenues falling under their responsibility and the delivery of services, as well as for the maintenance of an effective accounting and internal control systems. As such, they are accountable to the National Assembly for the management of public resources and for the performance of their departments.

Accountant-General
  The Accountant-General is the administrative head of the Treasury. He maintains the accounts of Government and ensures that accounting systems respond to Government’s needs for the proper processing, recording and accounting of financial transactions and for financial reporting. The Accountant-General prepares Annual Statements showing the financial transactions and financial position of the Republic of Mauritius and these are submitted to the Director of Audit. The statements give consolidated financial information on Ministries and Government Departments.

National Audit Office
  NAO plays an important role in the accountability process, providing a key link between the Legislature and the Executive. NAO gives an independent assurance to the National Assembly that Government entities are operating and accounting for their performance in accordance with the National Assembly’s purpose. Statutory responsibilities and powers have thus been conferred to the Director of Audit to enable him to fulfil his obligations. NAO examines the Annual Statements of the Republic of Mauritius, as well as the underlying records. The audit function and the submission of annual Audit Reports to the National Assembly by NAO is the first step in the process of oversight. After the Audit Reports are tabled, other important mechanisms are in place to ensure proper accountability.

Public Accounts Committee
  The Public Accounts Committee (PAC) represents Parliament and is one of the main stakeholders of the Report of the Director of Audit. It is a sessional Select Committee, appointed under the Standing Orders of the National Assembly, and consists of a Chairperson appointed by the Speaker and not more than nine members nominated by the Committee of Selection.

  As per the Standing Orders, the function of the Committee is to examine the audited accounts showing the appropriation of the sums granted by the Assembly to meet the public expenditure and such other accounts laid before the Assembly as the Assembly may refer to the Committee together with the Director of Audit’s report thereon. The Committee has the power, in the exercise of its duties, to send for persons and records, to take evidence, and to report from time to time. Also, the Rodrigues Regional Assembly (RRA) Standing Orders provide for the setting up of a PAC comprising a Chairperson and not more than four other members to examine the audited accounts showing the appropriation of the sums granted by the Regional Assembly to meet the public expenditure and other accounts laid before the Assembly together with the Report of the Director of Audit thereon.

1.3 Mandate of the NAO

1.3.1 Audit Portfolio

The Director of Audit has the responsibility to audit the accounts of:

  • All Ministries and Government Departments
  • All Commissions of the Rodrigues Regional Assembly
  • All Local Authorities
  • Most Statutory Bodies
  • Special Funds
  • Other Bodies and Donor-funded Projects
  • A few State-owned Companies
1.3.2 Types of Audit

  The NAO carries out two main types of audits, namely Regularity Audit and Performance Audit, to fulfill its audit mandate and to provide assurance to the National Assembly on the proper accounting and use of public resources.   Regularity Audit encompasses Financial Audit, Compliance Audit and Value for Money Audit, and involves:

  • Examination and evaluation of financial records and expression of opinions on financial statements
  • Attestation of financial accountability of the government administration as a whole
  • Audit of accounting systems and transactions including an evaluation of compliance with applicable statutes and regulations
  • Assessing whether expenditure is incurred with due regard to economy, efficiency and effectiveness.
  • Reporting of any other matters arising from or relating to the audit that the Supreme Audit Institution considers should be disclosed
  • Performance Audit is an independent, objective and reliable examination of whether Government undertakings, systems, operations, programmes, activities or organisations are operating in accordance with the principles of economy, efficiency and effectiveness.

Performance audit embraces:
● Audit of the economy of administration in accordance with sound administrative principles and practices, and management policies;

  • Audit of the efficiency of utilisation of human, financial and other resources, including examination of information systems, performance measures and monitoring arrangements, and procedures followed by audited entities for remedying identified deficiencies; and
  • Audit of the effectiveness of performance in relation to the achievement of the objectives of the audited entity, and audit of the actual impact of activities compared with the intended impact.
1.3.3 Legal Framework

  The legal framework within which NAO exercises its public-sector audit function is spelt out, primarily, in the following legislations:

  • The Constitution
  • Finance and Audit Act
  • Statutory Bodies (Accounts and Audit) Act
  • Local Government Act
  • Public Procurement Act
  • Financial Reporting Act
  • Agreements with several institutions/donor-funded agencies also empower the Director of Audit to audit their accounts.

 Constitution Section 110(2) provides that the public accounts of Mauritius and of all courts of law and all authorities and officers of the Government shall be audited and reported on by the Director of Audit. In the case of any body corporate directly established by law, the accounts of that body corporate shall be audited and reported on by the Director of Audit provided it is so prescribed.   Section 110(3) provides that the Director of Audit shall submit his reports to the Minister responsible for the subject of Finance, who shall cause them to be laid before the National Assembly.

1.4 Audit of Ministries and Government Departments – Finance and Audit Act

The duties of the Director of Audit are spelt out at Section 16 (1) of the Act. This subsection states that the Director of Audit shall satisfy himself –

Section 16(2) provides that the Director of Audit shall not be required to undertake any examination of accounts partaking of the nature of a pre-audit and involving acceptance by him of responsibility which would preclude him from full criticism of any accounting transactions after those transactions have been duly recorded. Section 19 provides that the Accountant-General shall within six months of the close of every fiscal year, sign and submit to the Director of Audit statements presenting fairly the financial transactions and financial position of Government on the last day of such fiscal year.

For the Rodrigues Regional Assembly, the Commissioner responsible for the subject of Finance must submit the respective statements within three months of the close of every fiscal year. Section 20 provides that the Director of Audit shall send to the Minister (responsible for the subject of Finance) copies of the statements submitted in accordance with Section 19 together with a certificate of audit and a report upon his examination and audit of all accounts relating to public money, stamps, securities, stores and other property –

1.8 The Public Procurement Act 6

Section 42 of the Public Procurement Act provides that the auditor of every public body (in our case the Director of Audit) shall state in his annual report whether the provisions of Part V of the Act on the Bidding Process have been complied with.

1.9 Audit Methodology

NAO conducts its audits in accordance with International Standards of Supreme Audit Institutions (ISSAIs) except for the audit of State-Owned companies (assigned to the Director of Audit) which are carried out in accordance with International Standards of Auditing. The audit approach of the NAO may be summarised as follows:

(a) NAO adopts a risk based approach by which audit resources are directed towards those areas of the financial statements that are more likely to contain material misstatements as a consequence of the risks faced by the client. We identify and assess the risks of material misstatement, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. (ISSAI 1315 Identifying and assessing the Risks of Material Misstatements through Understanding the Entity and Its Environment; ISSAI 1330 The Auditor’s Responses to Assessed Risks)

(b) We do not test all transactions but use sampling methods to select transactions and balances for testing. It is not cost effective to seek absolute certainty and therefore we look for reasonable assurance. Additionally, examining all data may still not provide absolute certainty because some data may not have been recorded. Audit sampling enables us to obtain and evaluate audit evidence about some characteristics of the items selected in order to form or assist in forming a conclusion concerning the population from which the sample is drawn. (ISSAI 1530 Audit Sampling)

(c) The primary responsibility for the prevention and detection of fraud rests with both those charged with governance of the entity and management. Our objective as auditors is to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatements, whether due to fraud or error. Owing to the inherent limitations of an audit (e.g. Client may provide incomplete information or falsify documents and use of sampling by audit), there is an unavoidable risk that some material misstatements of the financial statements may not be detected, even though the audit is properly planned and performed in accordance with the standards. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Consequently, fraud might remain concealed to us even if a thorough audit is conducted. (ISSAI 1240 The Auditor’s Responsibilities Relating to Fraud in an Audit of Financial Statements)

(d) Similarly, the primary responsibility for preventing and detecting corruption rests with the administrative or law enforcement authorities, such as the Police and the Independent Commission Against Corruption.
