Benchmark guidance

Insurance companies present unique challenges for materiality determination. Premium income drives the business, but the most significant balance sheet items — insurance contract liabilities and reserves — involve extensive actuarial estimation.

Choosing the right benchmark

Gross written premiums at 0.5–1% is the most common benchmark for insurance entities. Total assets at 0.5–1% is an alternative, particularly where investment portfolio management is as significant as underwriting.

Key audit considerations

Insurance contract liabilities under IFRS 17 involve significant actuarial estimates — fulfilment cash flows, risk adjustment, and the contractual service margin.

Claims reserves (both reported and IBNR) are the highest-risk area and typically warrant input from an auditor's actuarial expert.

Investment portfolio valuation may warrant specific materiality considerations.

Solvency II regulatory capital requirements create additional user needs beyond IFRS reporting.
