The 2008 financial crisis highlighted weaknesses in the risk management, control and governance processes of banks as well as in their statutory audit and financial supervision. This led to increased scrutiny of the respective roles and interactions of banking supervisors and external auditors who are key contributors to market discipline. Auditors ensure that financial information is transparent and reliable while supervisors provide confidence in the financial systems. Both supervisors and auditors allow market players to make informed decisions and contribute to financial stability.
The present Guide draws together recommendations to improve the relationship between supervisors and external auditors illustrated by good practices from 35 supervisory authorities across Europe and Central Asia (ECA). It has been developed as a supplement to the 2015 World Bank Centre for Financial Reporting Reform (CFRR) report on Banking Supervisors and External Auditors: Building a Constructive Relationship. Its main objective is to assist banking supervisors in managing their relationships with banks' auditors and in developing their policies which will contribute to build enhanced auditing and supervisory practices.
The Guide also takes into account the 2014 Guidance of the Basel Committee on Banking Supervision (BCBS) on External Audits of Banks and the 2016 European Banking Authority (EBA) Guidelines on the Communication between auditors and competent authorities. The CFRR's report and its work are acknowledged in the EBA guidelines.

In the UK, the Prudential Regulation Authority (PRA) provides joint regular training for supervisors on auditor- supervisor engagement, with a focus on how they might better understand the work of auditors as well as encouraging a more open and in-depth dialogue. |
What is an audit?*
An external audit is a process by which an independent external auditor will obtain sufficient appropriate audit evidence to give reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error. This enables the auditor to express an opinion on whether the financial statements are prepared, in all material respects, in accordance with an applicable financial reporting framework, and to report on the financial statements in accordance with the auditor's findings. Reasonable assurance is a high, but not absolute level of assurance. The independent opinion enhances the degree of confidence of intended users in the financial statements.
Observation | Possible actions | ||
The majority of European supervisors can ask external auditors to perform additional tasks outside the scope of the audit. However, practices vary across ECA in terms of the scope of auditors' work, the extent of auditors' contributions to the supervisory process, and the type of assurance they provide. |

External auditors do not always have the statutory duty to disclose significant findings and fraud encountered during the course of their audit (statutory duty to report). Furthermore, not all the jurisdictions provide "safe haven" rules for auditors when reporting matters to supervisors that do not give rise to a statutory duty to report but may, nevertheless, be relevant to the supervisor's exercise of his/her functions (right to report). |

Auditor's 'duty to report' in the EU legislation*
For the purposes of strengthening the prudential supervision of institutions and the protection of clients of institutions, auditors should have a duty to report promptly to the competent authorities, wherever, during the performance of their tasks, they become aware of certain facts which are liable to have a serious effect on the financial situation or the administrative and accounting organization of an institution. For the same reason Member States should also provide that such a duty applies in all circumstances where such facts are discovered by an auditor during the performance of his tasks in an undertaking which has close links with an institution.
Regular exchanges of information between external auditors and banking supervisors enable both parties to perform their duties effectively. A strong and fruitful two-way relationship depends on the quality of interaction between auditors and supervisors. The objective is to have "the right discussions at the right level and at the right time",* using the most appropriate channels of communication so that supervisors can engage more effectively with external auditors.
All European supervisors meet with external auditors but meetings typically occur at a late stage, mainly after the audit work has been completed and the audit report has been issued. For most European supervisors, direct meetings with external auditors without the bank's management, are the preferred option. Confidentiality remains an issue in other jurisdictions. Few jurisdictions provide "safe haven" rules for auditors when reporting matters to supervisors. Finally, very few jurisdictions have a feedback system in place to assess and monitor the quality of the relationship between supervisors and auditors.

In Belgium, the National Bank of Belgium (NBB) uses a proportionate approach when interacting with external auditors based on the risk profile of the bank, its size, and whether it is headquartered in Belgium. A set of criteria determines Systemically Important Financial Institutions (SIFI). SIFI meetings are conducted every quarter, whereas non-SIFI meetings are only conducted once per year. The NBB delegation includes more senior staff for meetings with SIFI. The NBB sends a copy of most of the communication between the NBB and the bank to the external auditor. |

While most supervisors mentioned the ability to have ad-hoc meetings with external auditors, the communication with external auditors often takes place only after the audit opinion has been issued. |

Generally, supervisors either use formal channels or an equal mix of both formal and informal channels when communicating with external auditors. European supervisors prefer discussing some matters directly with external auditors, without the presence of the bank under supervision (i.e. Bilateral meetings). |

To obtain the auditors' perspectives, each auditor was also asked to provide the PRA with its overall assessment of the quality of the external auditor- supervisor relationship. To help ensure that the auditors' findings were comparable with the results of the supervisors' survey, the PRA shared the list of firms covered in the survey as well as the full suite of survey questions addressed to supervisors with the auditors. Following the survey and report on the quality of auditor-supervisor dialogue in the summer of 2014, the following actions were undertaken:
The PRA uses biannual bilateral meetings with the senior financial services partners of the largest external audit firms to provide and receive feedback on the external auditor-supervisor engagement compared to the PRA Code. Hence the level of co-operation is kept under constant review. |

The Importance of the Management Letter*
Key features
A modern audit follows a risk-based approach, which focuses on the risks of material misstatements and how the audited entity mitigates these risks through its internal control system.
The management letter is a key output of the audit addressed to management in which the deficiencies and weaknesses in a bank's organizational structure are identified and eventual recommendations from external auditors on how to improve these internal control issues are presented. The bank's management usually provides a written response to the external auditor's remarks which is integrated into the management letter. The follow-up audit work should assess the progress made by the bank to implement the recommendations of the initial audit or fix the problems highlighted in the management letter. The management letter is often shared with supervisors and is also a key topic for discussions between external auditors and audit committees.
Importance for supervisors
The management letter details weaknesses in internal controls that could cause a material misstatement in the financial statement. Thus this document raises important points and summarizes the key areas for the attention of banking supervisors.

In the Netherlands, supervisors have, by law, the choice to share information with external auditors, but are not required to do so. Sometimes supervisors become aware of circumstances that can endanger "solutions" when discussed with auditors. In such cases supervisors do not share this sensitive information. If the information has or could have a direct influence on the auditor's opinion, the supervisor will share this information with external auditors. |
Information that supervisors could provide to external auditors**
General accounting topics:
- Assessments of the quality of published financial statements, the appendixes and areas identified for improvement;
- Views on the appropriateness of accounting judgments and materiality thresholds used.
Risks:
- Views of existing and/or upcoming macro- and micro-economic risks that banks might face. These could include global systemic risks, such as liquidity and refinancing problems;
- Other risks could include those related to the valuation of certain financial instruments or technical provisions, credit risk level on certain portfolios or the level of impairment attached to some asset classes. Views on the bank's loan loss provisioning could include, whenever possible, a comparison with other institutions on an unnamed basis;
- Information on issues such as governance, risk management, compliance framework and internal control that have a potential impact on the quality of financial reporting and regulatory information produced by the bank. For this purpose, the supervisor might share findings derived from his/ her on-site inspections;
- Measures implemented by the supervisor to prevent or limit the consequences or generalization of an identified risk.
Regulatory and accounting developments:
- The prudential treatment of a new type of product or operation and its eventual impact on accounting;
- Views on the interactions of new regulatory requirements with financial reporting practices and requirements;
- Information on potential issues identified and related to the application of new accounting standards or reporting practices. For example, the eventual impact of the accounting treatment of a new type of financial instrument or financial transaction as well as the impact of the new standard on regulatory requirements;
- Significant disagreements on the application of a new accounting, regulatory or prudential standard by the bank under supervision;
- Information on the progress of prudential regulation projects and the perspective of supervisors on accounting regulation projects.
Other:
- Correspondence between the supervisor and the bank's management, including certain instructions and minutes of meetings;
- Any intervention from the supervisor;
- Feedback on publications from the accounting profession;
- In general, all items that could have a material impact on banks' financial statements.

EU audit reform legislation – Requirements for rotation and retendering*
Audit firm rotation and audit retendering
From June 2016 onwards, Public Interest Entities (PIEs) are required to change their audit firms after a maximum 10-year mandate. The 10-year mandate can be extended by up to 10 additional years if tenders are carried out, and by up to 14 additional years in the case of a joint audit. In some exceptional circumstances, supervisors are empowered to extend the term once for a further two years at the request of the audited entity. There is the possibility to adopt a shorter rotation term.
Rotation of key audit partners
EU legislation requires the key audit partners of PIEs to rotate at least every seven years with a cooling off period of three years.
Extract from the Basel Core Principles (BCP) for Effective Banking Supervision - Principle 27 on financial reporting and external audit*
A snapshot of some essential criteria:
- The supervisor holds the bank's board and management responsible for ensuring that financial statements are prepared in accordance with accounting policies and practices that are widely accepted internationally. Furthermore, the financial statements should be supported by recordkeeping systems in order to produce adequate and reliable data;
- The supervisor holds the bank's board and management responsible for ensuring that the financial statements issued annually to the public bear an independent external auditor's opinion. This will be the result of an audit conducted in accordance with internationally accepted auditing practices and standards;
- The supervisor has the power to reject and rescind the appointment of an external auditor who is deemed to have inadequate expertise or independence, or is not subject to, or does not adhere to, established professional standards;
- The supervisor determines whether banks rotate their external auditors (either the firm or individuals within the firm) from time to time.

Although most of the supervisors have communication lines with AOBs, the frequency of meetings and communication with AOBs varies depending on the jurisdictions. In many jurisdictions, the professional organization for auditors is responsible for quality assurance. In the EU, a single competent authority will be designated to bear ultimate responsibility for the audit public oversight system (mandatory from 2016). |

This publication presents key findings from the World Bank CFRR survey – Financial supervisors and external auditors: building a constructive relationship that was conducted during the second half of 2014, and discussions with regulators conducted in 2015.
Responses from 35 supervisory authorities from the European Union and other countries in Eastern Europe, South Eastern Europe and the South Caucasus suggest that stronger two-way interaction between external auditors and supervisors can improve the quality of external audits and enhance banking supervision. This report highlights some actionable insights based on reported good practices that can be helpful to banking supervisors in managing their relationships with banks’ auditors. The report is can be used to define the necessary policies and guidelines towards building an enhanced collaboration between auditors and supervisors contributing to better auditing and supervisory practices.
