The requirement

R5400.51 — "A network firm shall be independent of the sustainability assurance clients of the other firms within the network as required by this Part."

The obligation runs outward. A firm that has no relationship at all with a particular client, and may never have heard of it, must nonetheless be independent of that client if another of the network firms performs a sustainability assurance engagement for it. Paragraph 5400.51 A1 confirms the reach: the independence requirements in this Part that apply to a network firm apply to any entity that meets the definition of a network firm — entity, not just accounting firm.

What counts as a network

Paragraph 5400.50 A1 sets the test:

"Firms frequently form larger structures with other firms and entities to enhance their ability to provide professional services. Whether these larger structures create a network depends on the particular facts and circumstances. It does not depend on whether the firms and entities are legally separate and distinct. Reference may be made to the Guidelines of Network issued by the Institute from time to time in this regard."

Legal separateness is expressly not the test

The single most common error in this area is to reason from structure: separate partnerships, separate LLPs, separate ownership, therefore no network. The Code forecloses that reasoning in terms. The determination is substantive — what the arrangement actually is — and the Indian reference point is the Guidelines of Network issued by the Institute, which the Code directs the reader to and which are updated from time to time. Check the current Guidelines rather than relying on a historic conclusion about the same arrangement.

The consequence of a network determination is substantial, because the network appears throughout the Independence Standards and the ethics standards alike:

  • R5400.20 — the prohibition on assuming a management responsibility applies to a firm or a network firm.
  • R5400.31(b) — previous services by the firm or a network firm must be considered on a new client.
  • R5400.32 — the public interest entity acceptance prohibition covers services provided by the firm or the network firm.
  • 5400.31 A3 and 5400.32 A1 — the re-performance safeguards require a firm outside of the network, so network firms are expressly disqualified from that role.
  • 5400.9 — individuals from within or outside the firm's network who perform assurance procedures are engagement team members.
  • R5310.7 — conflicts of interest arising from the interests and relationships of a network firm must be considered.
  • 5400.4 — the firm's policies and procedures must address others subject to independence requirements, including network firm personnel.

Making it work in practice

The practical difficulty with R5400.51 is informational: a firm cannot be independent of clients it does not know about. What the provisions above imply operationally:

  • A shared client and engagement register across all the network firms, covering sustainability assurance engagements, is the only reliable way to discharge R5400.51.
  • Independence declarations must be tested against the clients of other network firms, not only the firm's own.
  • The "has reason to believe" standard in R5310.7 for conflicts, and the general obligation here, mean that a firm which has structured itself so as not to know is not thereby protected.
  • Where the network spans jurisdictions, the geographic factor in paragraph 5310.7 A1 applies — relevant relationships may sit in a member firm the engagement team has never dealt with.

Communication with those charged with governance

Paragraph 5400.40 A1 points to R5300.9 and R5300.10 for the requirements on communicating with those charged with governance — determining the appropriate individuals, and deciding whether communication with a subgroup is sufficient.

Paragraph 5400.40 A2 then adds an encouragement that goes further than the requirements:

"Even when not required by the Code, applicable professional standards, laws or regulations, regular communication is encouraged between a firm and those charged with governance of the client regarding relationships and other matters that might, in the firm's opinion, reasonably bear on independence."

The Code explains what such communication enables those charged with governance to do:

  • (a) Consider the firm's judgments in identifying and evaluating threats;
  • (b) Consider how threats have been addressed, including the appropriateness of safeguards when they are available and capable of being applied; and
  • (c) Take appropriate action.

It adds that such an approach "can be particularly helpful with respect to intimidation and familiarity threats" — the two threat categories where the firm's own judgment is most likely to have been shaped by the very relationship being evaluated. That is a sound reason to treat 5400.40 A2 as a working practice rather than an optional courtesy.

Practical checklist

  • Determine network membership on facts and circumstances, not on legal structure, and check the Institute's current Guidelines of Network.
  • Maintain a network-wide register of sustainability assurance clients and engagements.
  • Test independence declarations against network clients as well as the firm's own.
  • Remember that network firms cannot perform the re-performance safeguards in 5400.31 A3 and 5400.32 A1.
  • Include network firm personnel in the firm's independence policies and procedures (5400.4).
  • Communicate regularly with those charged with governance on independence matters, especially where intimidation or familiarity threats are in play.

Common mistakes

  • Concluding there are no network firms because the entities are legally separate.
  • Relying on a historic network determination without checking the current Guidelines.
  • Screening only the firm's own client list.
  • Using a network firm to evaluate or re-perform a non-assurance service.
  • Excluding network firm personnel from independence monitoring.
  • Communicating with governance only when required, missing the value 5400.40 A2 identifies.
