The requirement, and the seniority expectation

Paragraph R5300.4 restates the obligation: the practitioner shall comply with the fundamental principles set out in Section 5110 and apply the conceptual framework set out in Section 5120 to identify, evaluate and address threats. Paragraph 5300.1 warns that Sections 5300 to 5390 do not describe all of the facts and circumstances that could create threats, so the framework requires practitioners to remain alert for others.

Paragraph 5300.5 A2 adds the seniority dimension — the more senior the practitioner, the greater the ability and opportunity to access information and influence policies and decisions, and the greater the expectation to promote an ethics-based culture through ethics education and training, firm processes and reward criteria, ethics and whistle-blowing policies, and policies designed to prevent non-compliance with laws and regulations.

What changes the level of a threat

Paragraphs 5300.7 A1 to A8 group the factors into three environments.

The client and its operating environment

Paragraph 5300.7 A3 says the evaluation might be impacted by whether the client is one:

  • (a) for which the practitioner performs a sustainability assurance engagement within the scope of the Independence Standards in this Part;
  • (b) for which the practitioner also performs an audit engagement;
  • (c) for which other assurance or non-assurance services are also provided, and their nature; or
  • (d) which is a public interest entity — the Code notes that providing a non-assurance service to a public interest entity client might be perceived to result in a higher level of threat to objectivity in respect of the sustainability assurance engagement.

Paragraph 5300.7 A4 adds governance factors that might reduce the level of a threat: the client requires appropriate individuals other than management to ratify or approve the appointment; the client has competent employees with experience and seniority to make managerial decisions; the client has internal procedures facilitating objective choices in tendering non-assurance engagements; and the client has a governance structure providing appropriate oversight and communications regarding the firm's services.

Paragraph 5300.7 A4a adds the value-chain factor discussed under Subsection 5113 — geographic dispersion of suppliers and the use of different reporting frameworks raise the competence-and-due-care threat.

The firm and its operating environment

Paragraph 5300.7 A5 lists what in the firm's own environment affects the evaluation:

  • Leadership that promotes compliance with the fundamental principles and sets the expectation that team members will act in the public interest.
  • Policies or procedures for establishing and monitoring compliance by all personnel.
  • Compensation, performance appraisal and disciplinary policies that promote compliance.
  • Management of the reliance on revenue received from a single client.
  • The engagement leader having authority within the firm for decisions concerning compliance, including decisions about accepting or providing services to a client.
  • Educational, training and experience requirements.
  • Processes to facilitate and address internal and external concerns or complaints.

Paragraph 5300.7 A6 adds the technology environment — corporate oversight and internal controls over the technology, third-party assessments of quality and functionality, and regular training.

New information

Paragraph 5300.7 A8 gives examples of changes that might impact the level of a threat: the scope of a service is expanded; the client becomes a listed entity or acquires another business unit; the firm merges with another firm; the practitioner is jointly engaged by two clients and a dispute emerges between them; or there is a change in the practitioner's personal or immediate family relationships.

The safeguards the Code names

Paragraph 5300.8 A2 gives examples of actions that in certain circumstances might be safeguards — each tied to the threat it addresses:

SafeguardThreat it might address
Assigning additional time and qualified personnel to required tasks when an engagement has been acceptedSelf-interest
Having an appropriate reviewer who was not a member of the team review the work performed or advise as necessarySelf-review
Using different leaders and teams with separate reporting lines for the provision of non-assurance servicesSelf-review, advocacy or familiarity
Involving another firm to perform or re-perform part of the engagementSelf-interest, self-review, advocacy, familiarity or intimidation
Disclosing referral fees or commission arrangements received for recommending services or productsSelf-interest
Separating teams when dealing with matters of a confidential natureSelf-interest
A safeguard has to be capable of working

Paragraph 5300.8 A2 is a list of examples, not a menu of approved answers — it opens with the words "Safeguards vary depending on the facts and circumstances." Read it with paragraph 5120.10 A2, which defines safeguards as actions that effectively reduce threats to an acceptable level, and paragraph 5120.10 A1, which says some threats can only be addressed by declining or ending the activity.

Paragraph 5300.8 A4 defines the reviewer that two of those safeguards depend on: an appropriate reviewer is "a professional with the necessary knowledge, skills, experience and authority to review, in an objective manner, the relevant work performed or service provided to a sustainability assurance client." Such an individual might be a sustainability assurance provider — which means the reviewer need not be one, provided the four attributes are present. Authority is one of the four, and it is the one most often missing when a firm nominates a reviewer junior to the engagement leader.

Communicating with those charged with governance

Two requirements govern this:

  • R5300.9 — when communicating with those charged with governance under this Part, the practitioner shall determine the appropriate individual(s) within the client's governance structure. If communicating with a subgroup, the practitioner shall determine whether communication with all of those charged with governance is also necessary so that they are adequately informed.
  • R5300.10 — if communicating with individuals who have management responsibilities as well as governance responsibilities, the practitioner shall be satisfied that this adequately informs all of those in a governance role with whom the practitioner would otherwise communicate.

Paragraph 5300.9 A1 says the practitioner might consider the nature and importance of the circumstances and the matter to be communicated. Paragraph 5300.9 A2 gives examples of a subgroup: an audit committee, another committee tasked with oversight of sustainability information, or an individual member of those charged with governance. Paragraph 5300.10 A1 addresses the owner-managed entity — where all those charged with governance are involved in managing the client, communicating with those individuals satisfies the requirement.

Using another practitioner's non-assurance work

Paragraph R5300.11 requires a practitioner who intends to use non-assurance work performed by another practitioner for the purposes of a sustainability assurance engagement to exercise professional judgment to determine the appropriate steps to take, if any, in order to fulfil responsibilities under integrity, objectivity and professional competence and due care.

Paragraph 5300.11 A2 gives the factors: the reputation and competence of, and resources available to, the other practitioner; and whether that other practitioner is subject to applicable professional and ethics standards. Such information might be gained from prior association or from consulting others.

Two cross-references that do not resolve within Volume III

Paragraph 5300.11 A1 excludes the work of an external expert, directing the reader to Section 5390, and directs a practitioner intending to use assurance work performed by another practitioner to Section 5406.

Neither section appears in the Volume III contents page, which runs 5100, 5110, 5120, 5270, 5300, 5310, 5320, 5330, 5340, 5350, then 5400 onwards. Before relying on either cross-reference, check the printed volume and any subsequent ICAI announcement — do not assume the content of a section that is not there.

Practical checklist

  • Identify at acceptance whether the client is a public interest entity and what other services the firm provides to it.
  • List the governance features of the client that reduce the threat, and say so in the evaluation.
  • For each safeguard proposed, name the threat it addresses and how it does so.
  • Test a nominated reviewer against all four attributes — knowledge, skills, experience and authority.
  • Decide deliberately whether a subgroup communication is sufficient under R5300.9.
  • Before relying on another practitioner's non-assurance work, assess reputation, competence, resources and whether they are subject to ethics standards.
  • Re-run the evaluation on any 5300.7 A8 event — scope expansion, listing, acquisition, firm merger, client dispute, or a change in family relationships.

Common mistakes

  • Treating the 5300.8 A2 list as a set of approved safeguards rather than examples that must actually work.
  • Appointing a reviewer without authority relative to the engagement leader.
  • Communicating only with an audit committee without considering whether the full governance body needs to be informed.
  • Assuming a public interest entity client is treated the same as any other for non-assurance services.
  • Accepting another practitioner's work without checking whether they are subject to ethics standards at all.
  • Re-evaluating only at acceptance and not on the events listed in 5300.7 A8.
