How a life & annuity insurer actually works
An insurer isn't a retailer with a margin. It's a balance sheet that takes on long-dated promises and invests against them. Understand the risks it absorbs and the spread it earns, and every other lens — capital, reinsurance, distribution, structure — falls into place.
The risks an insurer absorbs
People pay an insurer to carry risks they can't hold alone. Five pillars do most of the work — and the first two point in opposite directions, which is the industry's deepest hedge.
Life insurance pays a benefit if the policyholder dies during the term. The insurer loses if people die faster than its tables assume — a pandemic, say.
Annuities and pensions promise income for life. The insurer loses if people live longer than assumed and the payments outrun the reserve.
Health, disability, long-term-care and critical-illness covers pay when the insured can't work or needs care. Cost trends and claim duration drive the risk.
Premiums are invested in a general account of bonds, mortgages and alternatives. Rates, spreads and defaults move both the assets and the value of the promises.
Whether policyholders surrender, lapse or annuitize changes the economics — sometimes against the insurer (disintermediation when rates rise).
The economic engine: spread & fee
An insurer makes money two ways. It earns a spread between what it earns investing the premiums and what it credits or reserves for policyholders — and it earns fees on assets it manages (separate accounts, asset management).
This is why an insurer is read through its balance sheet, not a retailer's operating margin — see any firm's Fundamentals tab.
How the pieces connect
The operating loop ties every tenkviz lens together. Inflows create liabilities; liabilities are invested and must be backed by capital; risk is offloaded through reinsurance and captives; and the whole machine sits inside a legal-entity structure.
- 1DistributionAgents, IMOs, banks and broker-dealers bring in premiums and deposits.
- 2Reserves & liabilitiesThose promises become long-dated reserves on the balance sheet.
- 3General-account investingThe float is invested to earn the spread, matched to the liabilities.
- 4Capital & solvencyRegulators require a capital buffer sized to the risk — RBC, LICAT, Solvency II.
- 5Reinsurance & captivesRisk and reserve strain are ceded to reinsurers and affiliated captives.
- 6Entity structureAll of it sits in a web of legal entities across many jurisdictions.
How to read an insurer
Don't look for a fat operating margin. Look at the balance sheet: is net investment income covering the spread? Are reserves adequate? Is capital strong relative to the risk, and how much is financed through reinsurance or captives? Those questions — across the whole universe, traced to the filing — are what tenkviz is built to answer.
