Indian insurance investors often make the mistake of comparing ICICI Lombard (general insurance) with HDFC Life (life insurance) on similar metrics — P/E, book value, ROE. But these two businesses are structurally different in ways that make direct comparison meaningless without understanding the underlying accounting.
General Insurance: The Combined Ratio Framework
General insurance (motor, health, property, fire, marine) is a short-duration business — policies last 1-3 years, claims are paid within the policy period. The key profitability metric is the Combined Ratio = Loss Ratio + Expense Ratio. Loss Ratio = claims paid ÷ net premiums earned. Expense Ratio = operating expenses ÷ net premiums. A combined ratio below 100% means the insurance operations are profitable before investment income. ICICI Lombard consistently delivers 103-106% combined ratio — slightly unprofitable underwriting, made profitable by investment income on float.
Life Insurance: Duration, Float, and VNB
Life insurance is a long-duration business — policies run 10-30+ years. The float (premium collected upfront, invested until claims are paid) is massive relative to the current year's premiums. This is why Embedded Value (EV) — the present value of future profits plus adjusted net worth — is the correct valuation metric, not P/E. VNB margin (Value of New Business as a % of APE) measures how profitable the new policies being written today will be over their full lifetime.
- General insurance metric: Combined Ratio (below 100% = underwriting profit)
- Life insurance metric: VNB margin + EV growth
- ICICI Lombard combined ratio: ~103-106%
- Star Health (health-focused) combined ratio: ~97% (best-in-class)
- GWP growth — general insurance: 13-15% (India health insurance boom)
🔍 BBS Insight
The most attractive sub-segment in general insurance right now is health insurance — India's health insurance penetration is just 4% of population (vs 85% in the US), premiums are rising, and claim frequency is predictable enough for actuarial management. Star Health Insurance is a pure-play health insurer with consistent combined ratios below 100% — meaning it makes an underwriting profit before investment income. That is the highest-quality insurance business model. Track Star Health's loss ratio and renewals rate every quarter — those two numbers tell you everything about the health of the health insurance business.
