Financial ratio analysis for Insurance
Insurance company financial ratio analysis requires a specialised approach that accounts for the unique economics of underwriting and investment income. Traditional ratios like gross margin have limited meaning because the primary 'cost' — claims payments and reserve movements — is estimated rather than observed. The combined ratio (loss ratio + expense ratio), loss ratio, and Solvency II capital coverage ratio are the primary analytical metrics for insurance entities.
The Altman Z-Score is not applicable to insurance companies. Like banks, insurers operate with naturally high leverage and unique asset-liability structures that render the Z-Score meaningless. IFRS 17 (effective from 2023) has fundamentally changed how insurance contract revenue and liabilities are recognised, making pre-2023 ratio benchmarks less comparable. The contractual service margin (CSM) and risk adjustment components introduce new layers of estimation into the financial statements.
European insurance benchmarks from BACH show median ROE of 10.0% and median net margin of 8.0%. However, insurance profitability is highly cyclical — soft market conditions compress underwriting margins, while catastrophe events can cause sudden losses. When performing analytical procedures under ISA 520, auditors should compare loss ratios across accident years (not just calendar year), assess IBNR reserve adequacy trends, and analyse investment portfolio composition shifts that may indicate reaching for yield to offset underwriting losses.
