Life insurance is one of the most misunderstood sectors for equity investors, primarily because standard financial statement metrics — P/E, EBITDA, net profit margin — are nearly meaningless for evaluating insurance business quality. The sector has its own proprietary metrics, and understanding them is the price of entry for serious analysis.
Why PAT Is Misleading for Life Insurers
When an insurer sells a 20-year term policy, it receives a premium today but carries a liability to pay the death benefit (potentially) for 20 years. Accounting standards require the insurer to hold reserves — provisioning for future liabilities. These reserve requirements are determined by actuarial assumptions, not management discretion. The result: a highly profitable policy may actually show a PAT loss in Year 1 because the reserve provisioning exceeds the premium received.
Value of New Business (VNB) — The Right Profitability Metric
VNB is the present value of future profits from new policies written in the current year, calculated using actuarially determined assumptions. If an insurer writes ₹100 of new premium and its VNB is ₹25, its VNB margin is 25%. HDFC Life's VNB margin is consistently ~27-28%; SBI Life's is ~26-27%; LIC's is significantly lower at ~14-16%.
- HDFC Life VNB margin: ~27-28% | P/EV: ~2.5-3.0x
- SBI Life VNB margin: ~26-27% | P/EV: ~2.2-2.8x
- LIC VNB margin: ~14-16% | P/EV: ~0.8-1.1x (PSU discount)
- Key growth metric: APE (Annualised Premium Equivalent) growth
- Channel mix: bancassurance vs agency vs direct — affects cost ratio
🔍 BBS Insight
The three numbers to track every quarter for a life insurer: (1) APE growth — is the top-line growing? (2) VNB margin — is the quality of business improving (mix shift to higher-margin non-par and protection products)? (3) EV growth — is intrinsic value compounding? If all three are positive, the insurer is executing well regardless of what PAT says.
