Introduction

With the increase in corporate accounting scandals in the last decades, strict efforts are continuously being made by the accounting and auditing body for improving the quality of audit reporting. Accounting scandals such as the collapse of WorldCom, Enron and Lehman Brothers were a great shock to the whole world. It has resulted in the enhancement of reporting standards and requirements of auditing.

This report seeks to analyse and evaluate the role of the auditor in assuring the financial statement of entities and control the environment. The report will review and cover all the sections about the auditor role of ASX listed Company and will discuss independent auditor’s report, remuneration, role, functions, responsibilities, and key audit matters.

About the Company

 BHP Billiton is a multinational mining company headquartered in Melbourne, Australia. The company is engaged in the trading of mining, petroleum, and metals. Presently, Company is working with more than 60000 employees and earned revenue of US $38.285 billion in the year 2017 (BHP, 2017). The auditor of the Company is KPMG.

Auditor independence refers to the process of the audit which includes integrity and objectivity. Auditor independence requires an auditor to carry its responsibilities freely and in an objective manner.

As per section 307C of the Corporation Act, 2001, an auditor is required to give a declaration in writing that the auditor has not contravened the independent requirement of the auditor as per the act and code of professional conduct.

There is also no conflict of interest arise which is required to be disclosed by the auditor. The auditor did not commit any offence under subsection (2) of Section-324CA (BHP, 2017).

Non-audit Services

Non-audit services are services that have no connection with the audit process of an auditor and are provided by the auditor during the engagement of the audit period. Non-audit services of BHP Billiton are anti-corruption, insurance and security (Trompeter and Wright, 2010). The auditor of BHP Billiton may also provide other services such as the role of advocate, activities which normally take place under the function of management and may be required by the auditor to perform its own job.

Non-audit services of the Company have been approved under the process set for the provision of audit and other services by the external auditor. The company did not avail any non-audit services out of the policy.  Non-audit services are performed by Company with the prior approval of RAC. The services are incompatible with the general standards for the maintenance of auditor’s independence.

Analysis of the Auditor’s remuneration

As per the annual report of BHP Billiton, 2017 the remuneration of the auditor includes the fees payable to the group’s auditor for the purpose of assurance services, fees payable to the group’s auditors for other services (Norman et al., 2010). All amounts are paid to the KPMG and the affiliated firm of KPMG.

Furthermore, other services are related to corporate finance services such as divestment, rising of debt and acquisitions transactions. Other services also include non-statutory assurance based procedures, services related to tax compliances and advice on matters of accounting.

Key audit matters

The auditing standard 701 is for communication of key audit matters under the independent Auditor’s report. Key audit matters are those matters which require the significant judgment of the auditor (Mock and Turner, 2013). This matter offers additional information for the users of financial statements and is critically important for auditing financial statements. The matters provide an understanding of the vital management judgment in terms of financial statements being audited. The matters are assessed to be risky of material misstatement. The key audit matters as per the auditor’s report of BHP Billiton are here presented below:-

Further, comparing the assumptions of market observable data with risk-free rates.

Audit committee

BHP Billiton has an audit and risk committee comprising of three members having two non-executive directors and one chairperson who is not the chair of the board. The members are Frank Cooper (Chairman), David Crawford (Non-executive director) and Futhi Mtoba(Non-executive director). All the members are financial and accounting expertise and have a great understanding of the industry in order to discharge the mandate of the committee effectively.

            The responsibilities of the committee include the following:-

  • Monitoring and examine the related party transactions (Dechow, et. al., 2011).
  • Reviewing and monitoring the independence of external auditor and performance.

  • Overseeing the establishment, development, and management of risk management system in the light of risk appetite set by the board and appraise the effectiveness of the framework for risk management.

Auditor Opinion

The auditor of BHP Billiton has provided an unqualified opinion with respect to the financial statements and other compliances. Consolidated financial statements are also giving a true and fair picture of the group and properly prepared in consideration of international financial reporting standards.

The financial instruments and going concerning accounting is materially inconsistent as per the auditors and they have nothing to report in these respects.  The remuneration report of the Company is complying with section 300A of the Corporation Act, 2001.

Difference between Directors’ and Management’s responsibilities and auditor’s responsibilities

Directors are responsible for the preparation of financial statements which can provide a true and fair picture of financial position. Director0s are also requiring ensuring that the financial statements are as per the relevance framework of financial reporting. Further, directors are also responsible for the implementation of the necessary internal control which can enable the preparation of financial statements free from any fraud and error and does not contain any material misstatement (Arens, et. al., 2013).

Directors have to evaluate the ability of BHP Billiton to continue as a regular concern. For this proper disclosure on matters related to going concerned and use of accounting of going concerned unless they have any intention of ceasing the operations or liquidate the BHP Billiton and have no alternative realistic but to do so.

Auditors are responsible for obtaining reasonable assurance on fairness and truthfulness of financial statements and to ensure that financial statements are not materially misstated whether due to fraud, error or irregularities. Auditors are also required to issue auditor reports containing the opinion on the operations of BHP Billiton, internal control, risk management and other aspects required under the act.

Material subsequent events

In the year 2015, Company faced the Samarco dam failure which is in Minas Gerais, Brazil. There was the release of mine tailings, flooding which resulted in charges for the Company such as legal, advisory charges and loss of million amounted to $134 million (BHP, 2017). Dam failure impacted the communities of Gesteria, Bento Rodrigues, and Paracatu and other downstream communities. Samarco has been jointly owned by BHP Billiton has an equity investment of 50%.

The company identified contingent liabilities and provisions as a consequence of the failure of Dam. The company enters into a framework agreement and a preliminary agreement with the federal government and federal prosecutors in Brazil. This was executed with the purpose of developing and executive socio-economic programs in remediating the damage and outlining the negotiation for $20 billion.

Assessment of auditor report

The auditor report of BHP Billiton has demonstrated a clear view of the material and non-material information. Risk strategies, internal control system, operations and provision of remuneration have been observed by the auditor and presented in the report effectively (Murphy and Sandino, 2010).

Auditor has covered more on the financial statements and accounting but failed to put more light on the other non-financial information which can be material for the users of financial statements. The information in relation to the investment, divestment or risk management strategies could have also been stipulated in a more effective manner.

Effectiveness of material information

The failure of the Samarco dam seems to be under-reported. Although, Company has covered this material information in the annual report but failed to make it transparent. After such an incident, for an intended user, this information is extremely significant to understand the financial position of the Company.

Nevertheless, the annual report of BHP Billiton has covered useful information fully explained. But all the information should be included with simple statements understandable by an intended user. The company has complied with each regulation to cover up all material information.  

At the annual general meeting, I would like to ask the auditor of BHP Billiton about the matters in relation to the internal investigation of whistleblowers. I will also ask about the results of the mechanism. I will also for any deficiency in the internal control and if it is there then I will ask for an explanation in detail and any material weakness (Spira and Page, 2010). I will also ask for any unadjusted error schedule which has been disagreed with by management and the reason for not correcting such error.

Conclusion

The report went insight of the annual report and revealed many aspects of auditor included in the annual report of BHP Billiton. The report covered the requirement of independence, non-audit services, remuneration, responsibilities, key audit matters, and the audit committee. From the report, it has been learned that the auditor of the Company has performed its duty independently and effectively to a great extent. Material information should be provided with clarity by the auditor and must also get equal support from the director in doing so.
