Communication, Disclosure and Professional Reporting for Actuaries

Updated 11 October 2026 · Fact-checked

Professional reporting means giving advice that the reader can understand and act on. You state the purpose, data, assumptions, results and limits. You say what you relied on from others, get your work reviewed where required, and disclose material facts and conflicts to clients and regulators.

Understand Communication, Disclosure and Professional Reporting

Actuarial advice has no value if the reader cannot understand or use it. A trustee, a board or a regulator is rarely an actuary. So the actuary must turn technical work into a clear message that fits the reader's needs.

A good report has a clear purpose and audience. It gives the key result first, then the basis: data, methods, assumptions and limits. It separates fact from opinion and says how uncertain the results are. It should be complete enough that another competent actuary could understand how you reached your conclusions.

Actuaries rarely build everything themselves. You may rely on data from a client, a model built by a colleague, or a report from a lawyer or an auditor. Reliance is allowed, but responsibility stays with you. You should check the work is reasonable, judge whether the source is competent, and tell the reader what you relied on and what checks you did or did not do.

Peer review is a second competent person checking your work before it goes out. It catches errors, tests assumptions and challenges judgement. Its depth should match the risk and materiality of the work. Peer review supports your work but does not replace your own responsibility.

Disclosure means telling the right people what they need to know. This covers material limitations, conflicts of interest, and matters that the client or regulator would want to know. It is balanced by confidentiality. You keep client information private unless the law, the regulator or the profession's standards require or allow disclosure. Check the exact wording of IAI standards and the Actuaries' Code for the case you face.

How to solve Communication, Disclosure and Professional Reporting questions

Use this method for any case study or written question on communication, reliance, peer review or disclosure.

  1. 1Identify who the audience is and what decision they must make. State their level of technical knowledge.
  2. 2Identify the purpose of the communication and any legal, regulatory or professional standard that applies.
  3. 3List what the actuary relied on: data, models, others' opinions. Say what checks are reasonable and what must be disclosed.
  4. 4Decide whether peer review is needed. Link the depth to materiality, complexity and risk of harm.
  5. 5Decide what must be disclosed and to whom: limitations, uncertainty, conflicts, material facts. Weigh this against confidentiality.
  6. 6Say how to communicate: key message first, plain language, clear assumptions, written record, and suitable format.
  7. 7Conclude with a clear recommendation or action, and note any follow-up such as escalation to the regulator or client.

Quickest way: AURORA check: Audience, Reliance, Review, Open disclosure

When to use it: Use it for short written answers and MCQs when you have only a few minutes.

  1. Audience: who reads it and what do they need?
  2. Reliance: what was relied on, and was it checked and stated?
  3. Review: was peer review done, and is it proportionate?
  4. Open disclosure: limits, uncertainty, conflicts and material facts shared with the right party.
  5. Close with the action: what the actuary should do next.

Common mistakes in Communication, Disclosure and Professional Reporting

  • Writing a technical answer that ignores the audience.

    Students show off method rather than answer the reader's need.

    Fix: Name the audience first. Put the conclusion up front and explain jargon in plain words.

  • Saying that relying on someone else removes the actuary's responsibility.

    Students confuse using others' work with transferring accountability.

    Fix: State that the actuary remains responsible for judging whether reliance is reasonable and for disclosing it.

  • Treating peer review as optional or as a rubber stamp.

    Time pressure in real work makes review look like a formality.

    Fix: Link review to materiality and risk. Say the reviewer must be competent and independent of the work.

  • Disclosing everything to everyone, ignoring confidentiality.

    Students over-apply the idea of transparency.

    Fix: Disclose what is material to the right party. Keep other client information private unless law or standards require otherwise.

  • Leaving out limitations and uncertainty.

    Students think caveats make the advice look weak.

    Fix: State data gaps, assumption sensitivity and model limits. This protects the reader and you.

  • Giving a generic answer that does not use the case facts.

    Students recall a list rather than apply it.

    Fix: Quote at least two facts from the case in each point and tie each to a principle.

Worked examples

Example 1

An actuary values a client's pension scheme using member data supplied by the client. She notices that some dates of birth look wrong. The trustees want the report within a week. What should she do and how should she report?

Show the solution
  1. Audience and purpose: the trustees are non-actuaries who need a reliable valuation to make funding decisions.
  2. Reliance: she may rely on client data, but must judge whether it is reasonable. The errors suggest the data may not be fit for use.
  3. Checks: she should run reasonableness tests, ask the client to correct or explain the errors, and note which items remain unresolved.
  4. If correction is not possible in time, she should make and state a clear assumption for the doubtful records and test how much the result changes.
  5. Disclosure: the report should state the data source, checks done, the issues found, the approach used and the effect on results.
  6. Peer review: given the data problem, a review by a competent colleague is sensible before release.
  7. Communication: put the key result first, then the caveats, in plain language.

Answer: She may rely on the client's data only after reasonable checks. She should resolve or allow for the errors, disclose the data issues, approach and sensitivity, get peer review, and give the trustees a clear report with limits stated. Time pressure does not remove these duties.

Example 2

A life insurer's appointed actuary finds that a new pricing model, built by another team, produces results she cannot fully verify. Management wants her to sign off the product launch. Discuss her professional reporting duties.

Show the solution
  1. Reliance: she can rely on the model only if she has reasonable grounds to trust it. Inability to verify is a warning sign.
  2. She should request documentation, testing evidence and independent validation, such as parallel runs or reasonableness checks.
  3. Peer review: an independent review of the model is appropriate because the product launch is material.
  4. Disclosure to management: she should state clearly what she has and has not verified, and the risks of proceeding.
  5. If concerns remain, she should record her advice in writing and escalate to senior management or the board. She should consider any duty to inform the regulator as required by law and professional standards.
  6. Confidentiality: she shares company information only with those entitled or required to receive it.

Answer: She should not sign off blindly. She should seek validation and peer review, disclose in writing the limits of what she has verified and the risks, escalate if needed, and consider regulatory disclosure duties. Her responsibility remains even though others built the model.

Exam tips

  • In case studies, name the audience and purpose in your first line. Examiners reward advice that fits the reader.
  • Always say reliance is allowed but responsibility stays with the actuary. Then say what checks you would do.
  • Tie peer review to materiality and complexity. Do not claim every piece of work needs the same depth.
  • Use facts from the case in every point. Generic lists score poorly.
  • For disclosure questions, balance transparency against confidentiality and mention the regulator when the facts suggest it.

Communication, Disclosure and Professional Reporting: frequently asked questions

Can an actuary rely on data supplied by a client?

Yes, but only after reasonable checks. You should judge whether the data is fit for the purpose, state what you relied on and disclose any problems and their effect on results.

Does peer review remove the actuary's responsibility?

No. Peer review is an extra check. The actuary who signs the advice is still responsible for it.

What must be disclosed in an actuarial report?

Disclose the purpose, data, key assumptions, methods, results, uncertainty, limitations, reliance on others and any conflicts of interest. Always check the exact IAI standards that apply to the work.

How is this topic tested in CB3?

It appears in case-study style written questions and in MCQs. You are asked to apply principles to a scenario, so use facts from the case and give a clear recommendation.
