MetLife Inc. (MET)

MetLife is a diversified insurance company with operations across life insurance, annuities, employer benefits, property-casualty insurance, and asset management. It serves individuals, corporations, and institutions across the United States and a dozen countries. The company is a successor to the Metropolitan Life Insurance Company, founded in 1868, and trades as one of the largest financial-services companies by market capitalisation.

MetLife is an insurance conglomerate — a collection of different insurance businesses bundled under one corporate parent. Each business operates somewhat independently, with its own underwriting, pricing, and distribution, but they share infrastructure, brand, and capital. To understand MetLife, it helps to see the company not as a monolith but as a portfolio of distinct insurance franchises, each with its own economics and risks.

US Employee Benefits and Group Insurance

This segment offers health, disability, life, and accident insurance to employers and their employees. An employer contracts with MetLife to provide a menu of benefits — life insurance (say, twice salary), long-term disability (60 per cent of wages if unable to work), short-term disability, and supplemental coverages. Employees enrol in these plans, often subsidised by the employer, and pay premiums that MetLife collects.

This business is sticky. Once MetLife is the benefits provider, switching to a competitor requires administrative overhead, a new brokerage relationship, and employee re-education. Employers and employees tolerate existing plans until there is a compelling reason to change. The business generates steady, recurring premium income, though margins are modest because group insurance is commoditised and fiercely competitive.

The segment’s profitability depends on claims experience. If the insured group stays healthy and files few claims, underwriting profit is strong. If unexpected illness, death, or disability claims surge, profit erodes. MetLife manages this risk through careful underwriting (scrutinising the health and demographic profile of groups) and through reinsurance, which transfers some of the risk to specialist reinsurers.

Retirement and Income Solutions

This segment sells annuities — insurance products that trade cash today for guaranteed income tomorrow. A retiree might hand MetLife US$500,000 and receive US$2,500 per month for life. MetLife then invests that capital and makes profit if investment returns exceed the promised payments.

This segment is the earnings engine. Annuities carry higher margins than group insurance, and the business is large — MetLife holds billions of dollars in annuity reserves and is one of the largest pension de-risking providers in America. When a large pension plan wants to shed the risk of supporting retirees, MetLife often bids to assume those liabilities.

The profitability of annuities hinges on longevity assumptions and interest rates. MetLife models how long retirees will live; if actual lifespan exceeds the model, claims are larger and profit shrinks. Conversely, if mortality is better than expected (more people die earlier), profits rise. This is morbid arithmetic, but real: a company that underestimates lifespan on a large block of annuities faces a structural loss on that block.

Interest rates matter because MetLife invests the premiums in bonds and other fixed-income assets. When rates are high, new investments pay high returns, and annuity margins improve. When rates fall, new money earns less, squeezing margins on new sales.

Asia

MetLife operates in multiple Asian markets — Japan, South Korea, Hong Kong, Vietnam, and others — selling life insurance, disability insurance, and savings products. Asia is a growth region: rising middle-class incomes, improving life expectancy, and thin insurance penetration mean that demand for insurance is growing faster than in mature markets like the US.

Asian operations are profitable when the company wins market share and operates efficiently, but they carry regulatory risk (different countries impose different rules and reserve requirements) and market risk (insurance demand can swing sharply in a financial crisis). MetLife’s Asian business is a growth play, not yet a top contributor to earnings, but likely to become more important over time.

Property & Casualty Insurance

MetLife owns a significant property-casualty insurance business through subsidiaries, selling homeowner and auto insurance. This segment is highly competitive and cyclical: when price competition intensifies and claims are heavy, underwriting profit is thin. When pricing discipline holds and claims are light, profit can be strong. Catastrophic events — major hurricanes, floods, or wide-scale auto losses — can swing the segment’s annual profit sharply negative.

Property-casualty insurers manage this through pricing sophistication and reinsurance. MetLife uses detailed actuarial models to price policies, trying to charge each customer enough to cover expected claims. It also buys reinsurance to cap its exposure to catastrophic events, trading some profit for stability.

How MetLife actually makes money

Insurance company profit comes from two sources: underwriting profit (premiums exceed claims and expenses) and investment income (returns on the huge pool of money insurance companies manage). MetLife’s massive “float” — the cash and investments it holds on behalf of policyholders — generates billions in annual investment income. In years of high interest rates, this contribution is substantial and supports overall profitability.

The company is also active in asset management, running investment portfolios for institutional clients, which generates fee income.

Risks and competitive pressures

Insurance is highly capital-intensive and regulated. Regulators set reserve requirements (insurance companies must hold enough capital to cover potential claims) and enforce solvency rules. A major unexpected loss can threaten solvency if reserves are insufficient. MetLife manages this through conservative underwriting and excess capital, but stress events — a pandemic that drives up life-insurance claims, a catastrophic year for property damage — test those reserves.

There is also competitive pressure. Insurance distribution has been shifting online and toward direct-to-consumer channels, eroding broker relationships that MetLife historically relied on. Customers can now comparison-shop easily, which compresses margins on commoditised products like term life and auto insurance.

Regulatory risk is ever-present. Governments change rules around reserve requirements, minimum capital ratios, and product design. A significant rule change can alter the profitability of an entire segment.

Reading and understanding MetLife

The annual 10-K (SEC CIK 0001099219) is essential. It breaks revenue and profit by segment, discusses claims experience, reserve adequacy, and regulatory capital levels. Pay attention to the loss ratios in property-casualty (claims as a percentage of premiums) and to the changes in reserve levels for long-tail liabilities.

Watch for commentary on longevity trends and interest-rate assumptions. If management revises its assumptions about how long annuity holders will live, or if interest-rate forecasts change, reserves will shift and earnings will be affected.

Quarterly earnings calls reveal management’s stance on pricing in each segment and any emerging claims experience. In years with significant catastrophic losses, management will discuss how the company absorbed them and what adjustments are being made.

Finally, track capital ratios and the dividend. Insurance companies are valued partly on their capital efficiency — how much earnings they generate relative to the equity required to support the business. A strong capital position and a growing dividend signal confidence in underwriting and claims experience.
