The Financial Reporting Council (FRC) has today issued revised Technical Actuarial Guidance on Proportionality to support actuaries in applying principles-based Technical Actuarial Standards (TASs) in a proportionate and outcome driven manner.

The updated guidance includes additional material with new examples focused on general insurance pricing, illustrating the use of streamlined documentation and communication to support the efficient delivery of quality work within a tight time constraint. This update to the guidance follows feedback received during our TAS 200 consultation, where stakeholders indicated the value of further proportionality guidance in relation to general insurance pricing.

Quality actuarial work is vital to the effective functioning of the insurance market and pensions system. The principles-based TASs are designed to be applied proportionately and enable actuaries to tailor their approach based on the nature, scale, and complexity of the work whilst focusing on the core rationale behind the standards and supporting quality outcomes.

The revised Technical Actuarial Guidance on Proportionality is available on the FRC website.
